Please refer to FIG. 1 , which is a schematic structural diagram of a unified embodiment of a box system of the present invention.

In one embodiment, the box system can be applied to household electrical appliances such as ovens, refrigerators, and microwave ovens. The box system includes a box 10 and a door 20. The box 10 is a container for placing items in the household electrical appliance. The door 20 can be opened or closed relative to the box 10, so that when the door 20 is opened, items can be placed in the box 10, and when the door 20 is closed, a relatively closed space is formed inside the box 10.

Of course, the cabinet system of this embodiment can also be applied to equipment with a cabinet 10 and a door 20 in other fields, which is not limited here.

Specifically, the door body 20 is connected to the box body 10 through the hinge device 30. In other words, the door body 20 is opened or closed relative to the box body 10 through the hinge device 30. The hinge device 30 is described in detail below based on the scenario where the box system is applied to an oven. It is understood that the hinge device 30 of the box system of this embodiment is not limited to the following description.

Please refer to Figures 2 to 4, Figure 2 is a schematic structural diagram of an embodiment of a hinge device of the present invention, Figure 3 is a schematic structural diagram of the hinge device shown in Figure 2 after omitting the shell, and Figure 4 is a schematic structural diagram of the exploded hinge device shown in Figure 2.

In one embodiment, the hinge device 30 includes a hinge swing arm 31. The hinge swing arm 31 is used to connect an external structure. Specifically, when the hinge device 30 is applied to the above-mentioned box system, the hinge swing arm 31 is arranged on the door body of the box system. The hinge swing arm 31 has a first end 311 and a second end 312 that are arranged opposite to each other.

The hinge device 30 further includes a driving assembly 32. The driving assembly 32 is a power source of the hinge device 30, and is used to drive the hinge swing arm 31 to swing, so as to open and close the hinge device 30. The swinging of the hinge swing arm 31 is specifically manifested as the second end 312 of the hinge swing arm 31 swinging around the first end 311.

The hinge device 30 further includes an elastic member 33. The driving assembly 32 is in transmission connection with the hinge swing arm 31 through the elastic member 33. Specifically, the driving assembly 32 can adjust the deformation of the elastic member 33 so that the hinge swing arm 31 can drive the external structures of different weights to swing, and when the driving assembly 32 stops adjusting the deformation of the elastic member 33, the user is allowed to manually drive the hinge swing arm 31 to swing.

Please refer to Figure 5a and Figure 5b. The deformation of the elastic member 33 affects the torque applied by the elastic member 33 to the hinge swing arm 31. In other words, by adjusting the deformation of the elastic member 33, the torque applied by the elastic member 33 to the hinge swing arm 31 can be adjusted. The torque applied by the elastic member 33 to the hinge swing arm 31 is the first torque T1, and the torque applied by the self-gravity of the hinge swing arm 31 and the external structure connected to it (such as the above-mentioned door body, etc.) to the hinge swing arm 31 is the second torque T2, wherein the first torque T1 is opposite to the second torque T2. When the hinge device 30 is opened, the first torque T1 is less than the second torque T2; and when the hinge device 30 is closed, the first torque T1 is greater than the second torque T2, that is, the drive assembly 32 provides an electric drive method to drive the hinge device 30 to open or close.

Furthermore, when the driving assembly 32 stops adjusting the deformation of the elastic member 33, the user can directly operate the external structure connected to the hinge swing arm 31 to open or close the hinge device 30, that is, the user is allowed to manually drive the hinge swing arm 31 to swing, providing a manual driving mode to drive the hinge device 30 to open or close. Therefore, the hinge device 30 of this embodiment has a switching function between a manual driving mode and an electric driving mode, and can achieve barrier-free switching between the manual driving mode and the electric driving mode of the hinge device 30.

In addition, the elastic member 33 of the hinge device 30 of this embodiment can buffer the rigid impact force generated during the switching of the driving mode, which can reduce the risk of damage to the hinge device 30 due to excessive rigid impact force, and is beneficial to improving the structural reliability of the hinge device 30.

Taking the hinge device 30 of this embodiment applied to the above-mentioned box system as an example, when the door body is closed relative to the box body, the elastic member 33 has an initial deformation; and when the door body is opened relative to the box body, the driving component 32 is adjusted based on the initial deformation of the elastic member 33, so that the hinge swing arm 31 can drive the door body to swing. The hinge device 30 of this embodiment can adapt to door bodies of different weights. Even if there are differences in the weight of the door bodies, the deformation of the elastic member 33 is adjusted by the driving component 32, that is, the initial deformation of the elastic member 33 is adjusted, and the normal opening and closing of the door body can also be controlled. Compared with the traditional hinge mechanism, the hinge device 30 of this embodiment does not need to design corresponding elastic members 33 for door bodies of different weights, which can simplify the design of the hinge device 30 and reduce production costs.

It should be noted that the elastic restoring force provided by the elastic member 33 of this embodiment makes the second end 312 of the hinge swing arm 31 have a tendency to rotate around the first end 311, and the hinge swing arm 31 as a whole has a tendency to swing toward the driving assembly 32. In this way, when the hinge device 30 of this embodiment is applied to the above-mentioned box system, the hinge swing arm 31 makes the door body have a tendency to rotate toward the box body, which can realize the design of automatic closing of the door body and keep the door body tightly closed after the door body is closed.

Optionally, the elastic member 33 may be a tension spring, a compression spring, a belt, etc., which is not limited here.

Please continue to refer to Figures 2 to 4. In one embodiment, the driving assembly 32 includes a driving member 321. Optionally, the driving member 321 can be a motor, etc. The driving member 321 drives the driving end to rotate, so that the driving gear 323 rotates, thereby driving the moving member 322 to move.

The driving assembly 32 further includes a moving member 322 . The moving member 322 is connected to the driving member 321 and the elastic member 33 , respectively. The driving member 321 is used to drive the moving member 322 to move toward or away from the hinge swing arm 31 to adjust the deformation amount of the elastic member 33 .

For example, the elastic member 33 is preferably always in a stretched state. When the driving member 321 drives the moving member 322 to move toward the hinge swing arm 31, the distance between the moving member 322 and the hinge swing arm 31 decreases, so that the elongation of the elastic member 33 decreases, that is, the deformation of the elastic member 33 decreases, so that the torque applied by the elastic member 33 to the hinge swing arm 31 decreases, thereby opening the hinge device 30; and when the driving member 321 drives the moving member 322 to move away from the hinge swing arm 31, the distance between the moving member 322 and the hinge swing arm 31 increases, so that the elongation of the elastic member 33 increases, that is, the deformation of the elastic member 33 increases, so that the torque applied by the elastic member 33 to the hinge swing arm 31 increases, thereby closing the hinge device 30.

Of course, in other embodiments of the present invention, the elastic member 33 may also be in a compressed state all the time, and the position of the elastic member 33 may be adjusted to ensure that the elastic restoring force provided by the elastic member 33 makes the hinge swing arm 31 as a whole have a tendency to swing toward the driving assembly 32. Even, the elastic member 33 may be in a compressed state during the opening process of the hinge device 30, and in a stretched state during the closing process of the hinge device 30, etc., which is not limited here.

Furthermore, the driving assembly 32 further includes a driving gear 323. The driving member 321 has a driving end, and the driving gear 323 is transmission-connected to the driving end. The driving member 321 drives the gear 323 to rotate via the driving end.

The driving assembly 32 further includes a driving rack 324. The driving rack 324 is disposed on the moving member 322. The driving gear 323 is meshed with the driving rack 324. The driving member 321 drives the driving gear 323 to rotate through the driving end, so that the driving gear 323 drives the driving rack 324 to move, and then drives the moving member 322 to move through the driving rack 324.

Further, the hinge device 30 includes a base 34. A driving member 321 is disposed on the base 34, and a moving member 322 is movably disposed on the base 34. A slide rail 341 is also disposed on the base 34, and the slide rail 341 extends toward the hinge swing arm 31, and the moving member 322 is slidably disposed on the slide rail 341, and the slide rail 341 is used to guide the moving member 322 to move toward or away from the hinge swing arm 31.

Furthermore, the hinge device 30 further includes a housing 35. The housing 35 is fixed to the above-mentioned base 34. The housing 35 surrounds a space, and the elastic member 33 and the moving member 322 are both located in the space. The hinge device 30 further includes a guide shaft 325, and the guide shaft 325 is passed through the moving member 322. In addition, a guide groove 351 is provided on the housing 35, and the guide groove 351 extends toward the hinge swing arm 31, and the guide shaft 325 is embedded in the guide groove 351, and the guide shaft 325 can move along the guide groove 351.

When the driving member 321 drives the moving member 322 to move, the slide rail 341 on the base 34 guides the moving member 322 to move toward or away from the hinge swing arm 31, and the guide shaft 325 moves along the guide groove 351 to cooperate with the slide rail 341 to guide the moving member 322 to move toward or away from the hinge swing arm 31.

Of course, in other embodiments of the present invention, the driving component 32 is not limited to the above-mentioned method of driving the movable member 322 to move by the driving gear 323 and the driving rack 324. The driving member 321 can also drive the movable member 322 to move by a linear screw or the like, which is not limited here.

Please continue to refer to Figures 2 to 4. In one embodiment, the hinge device 30 further includes a gear transmission assembly 36. The elastic member 33 is transmission-connected to the hinge swing arm 31 via the gear transmission assembly 36. In other words, the elastic member 33 applies torque to the hinge swing arm 31 via the gear transmission assembly 36.

For example, the gear transmission assembly 36 includes a first transmission gear 361 and a second transmission gear 362. The first transmission gear 361 is connected to the elastic member 33. The elastic restoring force provided by the elastic member 33 can drive the first transmission gear 361 to rotate. The second transmission gear 362 is provided on the hinge swing arm 31, and specifically, the first end 311 of the hinge swing arm 31 is provided with the second transmission gear 362. The hinge swing arm 31 and the second transmission gear 362 can rotate synchronously, that is, the hinge swing arm 31 can rotate synchronously with the second transmission gear 362. The first transmission gear 361 is meshed with the second transmission gear 362, and the first transmission gear 361 and the second transmission gear 362 can rotate relative to each other. The elastic member 33 applies torque to the first transmission gear 361, so that the first transmission gear 361 applies torque to the second transmission gear 362, and then applies torque to the hinge swing arm 31, so that the hinge swing arm 31 has a tendency to swing toward the driving assembly 32.

During the opening process of the hinge device 30, the first transmission gear 361 and the second transmission gear 362 rotate relative to each other, the deformation of the elastic member 33 increases, and the hinge swing arm 31 swings away from the driving assembly 32; and during the closing process of the hinge device 30, the first transmission gear 361 and the second transmission gear 362 rotate relative to each other, the deformation of the elastic member 33 decreases, and the hinge swing arm 31 swings toward the driving assembly 32.

Furthermore, the hinge device 30 further includes a first fixed shaft 363 and a second fixed shaft 364. The first transmission gear 361 is sleeved on the outer circumference of the first fixed shaft 363, and the first transmission gear 361 is rotatably disposed on the housing 35 through the first fixed shaft 363. The second transmission gear 362 is sleeved on the outer circumference of the second fixed shaft 364, and the second transmission gear 362 is rotatably disposed on the housing 35 through the second fixed shaft 364.

Of course, in other embodiments of the present invention, the gear transmission assembly 36 may include a larger number of transmission gears and is not limited to the above-mentioned first transmission gear 361 and second transmission gear 362, so as to ensure that the torque applied by the elastic member 33 to the hinge swing arm 31 through the gear transmission assembly 36 can make the hinge swing arm 31 have a tendency to swing toward the driving assembly 32, and no limitation is made here.

It should be noted that in other embodiments of the present invention, the hinge device 30 may not be provided with a gear transmission assembly 36, but the elastic member 33 is directly connected to the hinge swing arm 31 to ensure that the torque applied by the elastic member 33 to the hinge swing arm 31 makes the hinge swing arm 31 have a tendency to swing toward the driving assembly 32.

Please continue to refer to Figures 2 to 4. In one embodiment, the hinge device 30 further includes a damping assembly 37. The damping assembly 37 contacts the gears of the gear transmission assembly 36, such as the first transmission gear 361 and the second transmission gear 362. The damping assembly 37 applies a damping force to the gears of the gear transmission assembly 36 by contact friction to hinder the rotation of the gears.

In the above manner, the damping assembly 37 can increase the friction resistance of the gears of the gear transmission assembly 36 during the rotation process, that is, increase the resistance of the hinge swing arm 31 during the swinging process, so that the swinging speed of the hinge swing arm 31 is not too fast, and it is convenient to control the swinging speed of the hinge swing arm 31. In particular, when the hinge device 30 of this embodiment is applied to the above-mentioned box system, the swinging speed of the hinge swing arm 31 is controlled, that is, the rotation speed of the door body is controlled, which can avoid many safety hazards caused by the excessive rotation speed of the door body.

It should be noted that the torque applied by the elastic member 33 to the hinge swing arm 31 is the first torque T1, and the torque applied by the gravity of the hinge swing arm 31 and the external structure connected thereto to the hinge swing arm 31 is the second torque T2. The damping assembly 37 applies torque to the hinge swing arm 31 through the gear transmission assembly 36, and the torque applied by the damping assembly 37 to the hinge swing arm 31 is the third torque T3.

Please refer to Figures 5a and 5b. When the hinge device 30 is driven by an electric drive, the drive assembly 32 adjusts the deformation of the elastic member 33 so that the first torque T1 provided by the elastic member 33 is greater than the combined torque of the second torque T2 and the third torque T3. At this time, the direction of the first torque T1 is opposite to the direction of the combined torque, and the hinge swing arm 31 automatically swings toward the drive assembly 32, that is, the hinge device 30 is closed, as shown in Figure 5a; and the drive assembly 32 adjusts the deformation of the elastic member 33 so that the combined torque of the first torque T1 and the third torque T3 is less than the second torque T2. At this time, the direction of the second torque T2 is opposite to the direction of the combined torque, and the hinge swing arm 31 automatically swings away from the drive assembly 32, that is, the hinge device 30 is opened, as shown in Figure 5b.

Please refer to Figure 6a and Figure 6b together. The box body and the door body are omitted in Figure 6a and Figure 6b, and the movement process of the door body is illustrated by the hinge swing arm 31. Among them, the hinge swing arm 31 shown by the dotted line in Figure 6a and Figure 6b is the position of the hinge swing arm 31 when the door body is closed to the box body.

When the hinge device 30 is driven manually, the user can directly operate the hinge swing arm 31 to swing toward the driving assembly 32, that is, the hinge device 30 is closed, or the user can directly operate the hinge swing arm 31 to swing away from the driving assembly 32, that is, the hinge device 30 is opened. Among them, when the angle θ at which the door body is opened relative to the box body is less than or equal to the threshold, the first torque T1 is greater than the combined torque of the second torque T2 and the third torque T3, and the direction of the first torque T1 is opposite to the direction of the combined torque. At this time, after the user releases the hinge swing arm 31, the hinge swing arm 31 will automatically swing toward the driving assembly 32 until the door body is closed in the box body, as shown in Figure 6a. In other words, the hinge device 30 of this embodiment can realize the automatic closing of the door body when it is opened at a small angle, which can reduce the user's operating burden and is conducive to improving the ease of use of the box system.

When the door is closed to the box, the elastic member 33 still has a certain deformation, that is, the elastic member 33 is still in a stretched state, for example, the elastic member 33 deviates from the horizontal plane by a certain angle. At this time, the first torque T1 is still greater than the combined torque of the second torque T2 and the third torque T3, and the direction of the first torque T1 is opposite to the direction of the combined torque, thereby keeping the door tightly closed.

When the angle θ at which the door is opened relative to the box is greater than a threshold, the resultant torque of the first torque T1 and the third torque T3 is balanced with the second torque T2, that is, the resultant torque is equal to the second torque T2, and the direction of the resultant torque is opposite to the direction of the second torque T2. At this time, after the user releases the hinge swing arm 31, the hinge swing arm 31 stops swinging, that is, the door body hovers at the current position, as shown in FIG6b. In other words, the hinge device 30 of this embodiment can realize that the door body hovers at any position when it is opened at a larger angle, which is convenient for users to take items out of the box or put items into the box.

Optionally, the threshold value may be 5° to 10°, such as 8°, etc. By setting the threshold value reasonably, the requirements of the hinge device 30 for automatic closing at a small angle and hovering at any position at a large angle in most application scenarios can be met.

Further, the damping assembly 37 includes a damping member 371 and an adjusting member 372. The adjusting member 372 and the gear of the gear transmission assembly 36 clamp the damping member 371, for example, the damping member 371 is sandwiched between the adjusting member 372 and the first transmission gear 361, and/or the damping member 371 is sandwiched between the adjusting member 372 and the second transmission gear 362. The adjusting member 372 cooperates with the gear to clamp the damping member 371, so that the damping member 371 applies a damping force to the gear.

In addition, the distance between the adjusting member 372 and the gear of the gear transmission assembly 36 is adjustable, that is, by adjusting the distance between the adjusting member 372 and the gear, the clamping degree of the damping member 371 can be adjusted, thereby adjusting the damping force applied by the damping member 371 to the gear of the gear transmission assembly 36.

In other words, this embodiment can reasonably set the damping force provided by the damping member 371 according to the weight of the external structure (such as a door body, etc.) to which the hinge swing arm 31 is connected and the requirement for the rotation speed of the hinge swing arm 31, which can not only prevent the hinge swing arm 31 from rotating too fast, but also ensure the function of automatic closing at a small angle and hovering at any position at a large angle of the hinge device 30.

Furthermore, the gears of the gear transmission assembly 36 are provided with adjustment members 372 on both sides, and the adjustment members 372 on both sides cooperate with the clamping gear to fix the position of the gear on the fixed shaft. Based on the above-mentioned example of the first transmission gear 361 and the second transmission gear 362, the first transmission gear 361 is provided with adjustment members 372 on both sides, and the adjustment members 372 on both sides cooperate with the clamping of the first transmission gear 361 to fix the position of the first transmission gear 361 on the first fixed shaft 363; and/or, the second transmission gear 362 is provided with adjustment members 372 on both sides, and the adjustment members 372 on both sides cooperate with the clamping of the second transmission gear 362 to fix the position of the second transmission gear 362 on the second fixed shaft 364. In addition, the first transmission gear 361 is provided with damping members 371 on both sides, and/or the second transmission gear 362 is provided with damping members 371 on both sides.

In one embodiment, the hinge device 30 also includes a sensor (not shown). When the hinge device 30 is applied to the above-mentioned box system, the sensor can be arranged on the door body. The sensor is used to sense in real time whether there is a sudden change in the acceleration of the hinge swing arm 31, that is, to sense whether there is a sudden change in the acceleration of the door body. In the process of driving the hinge device 30 by electric drive, there is no obvious sudden change in the acceleration of the hinge swing arm 31, but when the user intervenes, there will be an obvious sudden change in the acceleration of the hinge swing arm 31. For example, in the process of driving the hinge device 30 by electric drive, the user suddenly manually operates the door body, intervenes in the opening and closing process of the door body, causes a sudden change in the acceleration of the door body, that is, there is a sudden change in the acceleration of the hinge swing arm 31, which is then sensed by the sensor.

When the sensor senses that there is a sudden change in the acceleration of the hinge swing arm 31, the drive assembly 32 stops adjusting the deformation of the elastic member 33, allowing the user to manually drive the hinge swing arm 31 to swing, that is, to switch from the electric drive mode to the manual drive mode without any obstacles. In the process of driving the hinge device 30 by manual drive, the hinge device 30 has the above-mentioned functions of automatic closing at a small angle and hovering at any position at a large angle. In other words, the hinge device 30 of this embodiment can be switched to the manual drive mode at any time during the process of being driven by the electric drive mode, and can be switched to the electric drive mode at any time during the process of being driven by the manual drive mode.

Furthermore, when the sensor senses that there is a sudden change in the acceleration of the hinge swing arm 31, the drive assembly 32 adjusts the deformation of the elastic member 33 back to the initial state, and then stops adjusting the deformation of the elastic member 33. The initial state is defined as the initial deformation of the elastic member 33. When the deformation of the elastic member 33 is in the initial state, when the angle at which the door body is opened relative to the box body is less than or equal to the threshold, the first torque is greater than the resultant torque of the second torque and the third torque, and the direction of the first torque is opposite to the direction of the resultant torque, and when the angle at which the door body is opened relative to the box body is greater than the threshold, the resultant torque of the first torque and the third torque is balanced with the second torque. In other words, the deformation of the elastic member 33 is in the initial state, which can ensure that the hinge device 30 can automatically close at a small angle and hover at any position at a large angle.

It should be noted that when the sensor senses that the acceleration of the hinge swing arm 31 has a sudden change, the driving member 321 drives the moving member 322 to move to the initial position, so that the deformation of the elastic member 33 is adjusted back to the initial state. In addition, the principle of the sensor sensing the sudden change of acceleration belongs to the understanding of those skilled in the art, and will not be repeated here.

In summary, the hinge device and box system provided by the present invention. The driving component of the hinge device is connected to the hinge swing arm through an elastic member, and the driving component can adjust the deformation of the elastic member so that the hinge swing arm drives external structures of different weights (such as door bodies, etc.) to swing. In other words, the hinge device of the present invention can adapt to external structures of different weights by adjusting the deformation of the elastic member, that is, the hinge device of the present invention has good compatibility, which is conducive to reducing the cost of the hinge device.
