A center of gravity biasing device and an electronic apparatus according to an embodiment of the present application are described below with reference to fig. 1 to 9.

The application provides a gravity center biasing device which can be applied to electronic equipment such as a tablet personal computer and a mobile phone, in particular to a large-screen mobile phone such as a folding screen or a scroll screen.

Fig. 1 is a schematic structural diagram of a gravity center biasing device according to the present application, and fig. 2 is a schematic explosive structural diagram of a gravity center biasing device according to the present application. Some embodiments of the present application provide a center of gravity biasing device 100 that includes a housing 1, a mass 2, and a balancing mechanism 3. The shell 1 is provided with a chute 11, and the mass block 2 is slidably arranged in the chute 11. The balance mechanism 3 is connected to both ends of the mass 2 in the sliding direction thereof, respectively, and applies forces in opposite directions to both ends of the mass 2, respectively. In the first state of the housing 1, the mass 2 is in the middle position of the slide 11 by the balancing device 3. With the housing 1 in the second state, the mass 2 can slide to one end of the chute 11 under the force of its gravity, shifting the center of gravity of the center of gravity biasing means. Wherein the sliding direction of the mass block 2 is consistent with the length direction of the chute 11.

Specifically, the first state of the housing 1 is a state when the groove bottom of the chute 11 is parallel to the horizontal plane, and the second state of the housing 1 may be a state when one end of the chute 11 is inclined downward with respect to the horizontal plane. The middle position of the chute 11 refers to a position between two ends of the chute 11 in the length direction, and when the mass block 2 is located at the middle position of the chute 11, a certain distance exists between the two ends and the housing 1. Alternatively, the mass 2 is located at the very center in the length direction of the chute 11 when the housing 1 is in the first state. The mass 2 has a first end 21 and a second end 22 in its sliding direction. The balance mechanism 3 is connected to the first end 21 and the second end 22, respectively, to apply opposing forces to the masses 2, respectively.

When the housing 1 is in the first state, the forces of the balancing mechanism 3 on the first end 21 and the second end 22 are equal and opposite. At this time, the mass 2 is positioned at the middle position of the chute 11 under the forces in the two directions of the balance mechanism 3, and the gravity center biasing device 100 is in a horizontal balance state. When the housing 1 is in the second state, the mass 2 slides relative to the chute 11 under the action of gravity and reaches one end of the chute 11. At this time, the center of gravity biasing device 100 is in the center of gravity biasing state.

The second end 22 of the mass 2 is defined as a first direction pointing in the direction of the first end 21, and the direction of the first end 21 pointing in the second end 22 is defined as a second direction.

For example, when a person holds the mobile phone, the mobile phone is tilted with respect to the horizontal plane, so that the side of the housing 1 of the gravity center biasing device 100 near the first end 21 is tilted downward in the gravity direction with respect to the side thereof near the second end 22, the mass 2 slides in the first direction. Conversely, if the side of the housing 1 near the second end 22 is inclined downward in the direction of gravity with respect to the side thereof near the first end 21, the mass 2 slides in the second direction.

In some of these embodiments, the counterbalance mechanism 3 applies a first directional force to the first end 21 and a second directional force to the second end 22. In other embodiments, the counterbalance mechanism 3 applies a force in the second direction to the first end 21 and a force in the first direction to the second end 22.

According to the gravity center biasing device 100 provided by the application, the sliding groove 11 is arranged in the shell 1, the mass block 2 is arranged in the sliding groove 11, so that the mass block 2 can slide to one end of the sliding groove 11 under the action of gravity of the shell 1 in the second inclined state, and the gravity center of the gravity center biasing device is offset. By providing the balancing mechanism 3, the balancing mechanism 3 keeps the mass 2 in the middle position of the chute 11 when the housing 1 is in the first state. When the center of gravity biasing device 100 is attached to an electronic device, a user can adjust the center of gravity of the electronic device in the direction of the palm of the hand by the center biasing device, thereby improving the problem of discomfort of the wrist caused by holding a large-sized electronic device with one hand of the user.

In the embodiment of the present application, when the housing 1 is in the first state, the resultant force of the forces applied to the first end 21 and the second end 22 by the balance mechanism 3 is zero; when the housing 1 is in the second state, the magnitude of the resultant force of the forces of the balance mechanism 3 on the first end 21 and the second end 22 changes.

According to some embodiments of the present application, as shown in fig. 1 and 2, the balance mechanism 3 includes two elastic restoring members 31, and the two elastic restoring members 31 are respectively located between both ends of the mass 2 in the sliding direction thereof and the housing 1. The elastic restoring member 31 may be a restoring spring, a restoring spring piece, or other structural members that can provide elastic restoring force.

Wherein both elastic restoring members 31 may be in a compressed state or in a stretched state or in a state neither compressed nor stretched. The present application is specifically illustrated with two elastic restoring members 31 in a compressed state.

Specifically, the two elastic restoring members 31 are a first elastic restoring member and a second elastic restoring member, respectively. The first elastic restoring member has both ends connected to the first end 21 and the housing 1, respectively, and applies a force in a second direction to the first end 21. The two ends of the second elastic restoring member are respectively connected with the second end 22 and the shell 1, and force in the first direction is applied to the second end 22.

With the housing 1 in the first state, the two elastic restoring elements 31 delimit the mass 2 in the center position of the slide 11. With the housing 1 in the second state, the mass 2 slides relative to the housing 1 under its weight and eventually reaches one end of the chute 11. When the housing 1 is restored from the second state to the first state, the mass 2 is restored to the intermediate position of the chute 11 by the elastic restoring force of the two elastic restoring members 31.

For example, the side of the housing 1 near the first end 21 is inclined downward in the gravitational direction with respect to the side thereof near the second end 22, the amount of compression of the first elastic restoring member increases, and the elastic restoring force applied to the mass 2 increases; the compression amount of the second elastic restoring member decreases, and the elastic restoring force applied to the mass 2 decreases. Thereby forming resistance to the sliding of the mass 2, and having a buffering function, the center of gravity of the center of gravity biasing device 100 is shifted more smoothly.

It should be noted that, when the side of the housing 1 near the second end 22 is inclined downward in the gravity direction relative to the side near the first end 21, the action mechanism of the elastic restoring member 31 can be similarly pushed according to the above embodiment, and will not be described herein.

According to some embodiments of the application, as shown in fig. 1 and 2, the balancing mechanism 3 further comprises two electromagnetic driving members 32. The electromagnetic driving members 32 include oppositely disposed coils and permanent magnets, one of the coils and permanent magnets of each electromagnetic driving member 32 being connected to the housing 1 as a fixed end 321 of the electromagnetic driving member 32, and the other being connected to the mass 2 as a driving end 322 of the electromagnetic driving member 32. The fixed ends 321 of the two electromagnetic driving members 32 are respectively opposed to both ends in the sliding direction of the mass 2.

Specifically, the coil is connected with a direct current power supply, and electromagnetic force is generated between the coil and the corresponding permanent magnet. As shown in fig. 1, the two electromagnetic drivers 32 are a first electromagnetic driver and a second electromagnetic driver, respectively. The driving end 322 of the first electromagnetic driving member is connected with the first end 21 of the mass 2, and the driving end 322 of the second electromagnetic driving member is connected with the second end of the mass 2. The fixed ends of the two electromagnetic driving members 32 are respectively opposed to both ends of the mass 2 in the sliding direction thereof.

One of the coil and the permanent magnet of each electromagnetic driving member 32 serves as a fixed end, and the other serves as a driving end 322, and the present application is not particularly limited as to the specific arrangement positions of the coil and the permanent magnet. As long as the magnetic force generated by the first electromagnetic driving piece is opposite to the magnetic force generated by the second electromagnetic driving piece. When the permanent magnets of the two electromagnetic driving members 32 are both used as the driving end 322 and the magnetic pole directions of the two permanent magnets are the same, the permanent magnets of the two electromagnetic driving members 32 may be in an integrally formed structure.

When the magnetic pole directions of the coil and the permanent magnet of the electromagnetic driving member 32 are opposite, a repulsive force is generated between the coil and the permanent magnet, the first electromagnetic driving member applies a repulsive force in a second direction to the mass block 2 through the driving end 322 thereof, and the second electromagnetic driving member applies a repulsive force in a first direction to the mass block 2 through the driving end 322 thereof.

When the magnetic pole directions of the coil and the permanent magnet of the electromagnetic driving member 32 are the same, suction force is generated between the coil and the permanent magnet, the first electromagnetic driving member applies suction force in a first direction to the mass block 2 through the driving end 322 thereof, and the second electromagnetic driving member applies suction force in a second direction to the mass block 2 through the driving end 322 thereof.

With the housing 1 in the first state, the two electromagnetic drives 32 delimit the mass 2 in the middle position of the slide 11. With the housing 1 in the second state, the mass 2 slides relative to the housing 1 under its weight and eventually reaches one end of the chute 11.

For example, the side of the housing 1 near the first end 21 is inclined downward in the direction of gravity with respect to the side thereof near the second end 22, the distance between the coil of the first electromagnetic driving member and the permanent magnet decreases, the electromagnetic force thereof against the mass 2 increases, the distance between the coil of the second electromagnetic driving member and the permanent magnet increases, and the electromagnetic force thereof against the mass 2 decreases. When the magnetic poles of the coil and the permanent magnet of the electromagnetic drive 32 are opposite, the impact force of the mass 2 with the housing 1 is reduced. When the magnetic pole directions of the coil and the permanent magnet of the electromagnetic driver 32 are the same, the sliding of the mass 2 is promoted, and the sensitivity of the gravity center biasing device 100 is improved.

It should be noted that, when the side of the housing 1 near the second end 22 is inclined downward in the gravity direction relative to the side near the first end 21, the action mechanism of the electromagnetic driving member 32 may be similarly deduced according to the above embodiment, and will not be described herein.

Further, according to some embodiments of the present application, the balancing mechanism 3 comprises two elastic return members 31 and two electromagnetic driving members 32 simultaneously. In the first state of the housing 1, the two elastic restoring elements 31 and the two electromagnetic drives together define the mass 2 in the center of the slot 11. In the case that the housing 1 is in the second state, the mass 2 slides relative to the housing 1 under the action of gravity, and the action mechanism of the two elastic restoring members 31 and the two electromagnetic driving members 32 on the mass 2 can be referred to the above embodiments, which are not described herein. The present embodiment can improve the reliability of the balance mechanism 3 by providing the elastic restoring member 31 and the electromagnetic driving member 32.

According to some embodiments of the present application, as shown in fig. 1 and 2, the gravity center biasing device further includes two plate capacitors 33, and the two plate capacitors 33 are arranged at intervals along the sliding direction of the mass 2 and are respectively in one-to-one correspondence with the two electromagnetic driving members 32. The two electrode plates 331 of each plate capacitor 33 are oppositely disposed at two sides of the sliding chute 11 in the sliding direction of the mass 2 and are electrically connected to two ends of the coil of the corresponding electromagnetic driving member 32.

With the housing 1 in the first state, the mass 2 is located between the two plate capacitors 33. With the housing 1 in the second state, the mass (2) may be offset toward one of the plate capacitors 33 and inserted between the two electrode plates 331 of the plate capacitor 33, eventually reaching one end of the chute 11.

In the case where the case 1 is in the first state, the mass 2 is located between the two plate capacitors 33, which means that the mass 2 is located entirely outside the two plate capacitors 33, or that both ends of the mass 2 in the sliding direction thereof are located between the two electrode plates 331 of the two plate capacitors 33, respectively, that is, both ends thereof extend partially into between the two electrode plates 331 of the two plate capacitors 33, respectively.

The following embodiment will specifically describe an example in which both ends of the mass 2 in the sliding direction thereof are respectively located between the two electrode plates 331 of the two plate capacitors 33 when the housing 1 is in the first state.

Specifically, the two plate capacitors 33 are a first plate capacitor and a second plate capacitor, respectively. The first plate capacitor and the second plate capacitor are arranged at intervals along the sliding direction of the mass block 2, the coils of the first plate capacitor and the first electromagnetic driving piece are connected in parallel with the two ends of the direct current power supply, and the coils of the second plate capacitor and the second electromagnetic driving piece are connected in parallel with the two ends of the direct current power supply.

Fig. 3 is a schematic view showing a gravity center biasing device according to the present application in a first state, in which the mass 2 is located between two plate capacitors 33 with the housing 1 in the first state. As shown in fig. 4, when the side of the housing 1 near the first end 21 is inclined downward in the gravity direction relative to the side near the second end 22, the mass 2 slides in the direction of the first plate capacitor and is inserted between the two electrode plates 331 of the first plate capacitor.

The mass 2 may be an insulator or a conductor. When the first end of the mass 2 is inserted between the two electrode plates of the first plate capacitor, the other end is drawn out from between the two electrode plates 331 of the second plate capacitor. So that the potential difference across the first plate capacitor is reduced while the potential difference across the second plate capacitor is increased. Thereby reducing the force of the first electromagnetic drive against the mass 2 and increasing the force of the second electromagnetic drive against the mass 2.

It should be noted that, when the side of the housing 1 near the second end 22 is inclined downward in the gravity direction relative to the side near the first end 21, the action mechanism of the mass 2 and the plate capacitor 33 can be similarly deduced according to the above embodiment, and will not be repeated here.

Wherein the amount of change in the force of the electromagnetic driver 32 against the mass 2 due to the change in the potential difference of the plate capacitor 33 is greater than the amount of change in the force of the mass 2 due to the change in the spacing between the coils and the permanent magnets of the electromagnetic driver 32. Thus when a plate capacitor 33 is provided, a change in the potential difference of the plate capacitor 33 causes the electromagnetic drive 32 to dominate a change in the force of the mass 2. When the magnetic pole directions of the coil and the permanent magnet of the electromagnetic driving member 32 are the same, the attraction force to the end of the mass block 2 close to the sliding direction thereof is reduced, and the attraction force to the end of the mass block 2 far from the sliding direction thereof is increased, so that the impact force between the mass block 2 and the housing 1 can be reduced, and the gravity center offset of the gravity center offset device 100 is more stable.

When the magnetic pole directions of the coil and the permanent magnet of the electromagnetic driving member 32 are opposite, the repulsive force thereof against the end of the mass 2 close to the sliding direction thereof is reduced, while the repulsive force against the end of the mass 2 away from the sliding direction thereof is increased. In the case where the mass of the mass 2 is small or the sliding condition of the mass 2 and the housing 1 is insufficient, the sliding of the mass 2 can be promoted, and the sensitivity of the gravity center biasing device 100 can be improved.

According to some embodiments of the application, the gravity center biasing device further comprises a dielectric plate 34, wherein the dielectric plate 34 is arranged on the mass 2. And can move between the two electrode plates 331 of the plate capacitor 33 under the sliding drive of the mass block 2.

The dielectric plate 34 may be integrally formed with the mass 2 or may be provided as an independent component inside or outside the mass 2, so long as it can be driven by the mass 2 to move between the two electrode plates 331 of the two plate capacitors 33. The effect of the movement of the dielectric plate 34 between the plates of the plate capacitor 33 on the capacitance of the plate capacitor 33 is the same as the effect of the mass 2 on the capacitance of the plate capacitor 33, and will not be described again.

According to some embodiments of the present application, when the magnetic pole directions of the coil and the permanent magnet of the electromagnetic driver 32 are the same, and both ends of the mass 2 in the sliding direction thereof are respectively located between the two electrode plates 331 of the two plate capacitors 33 with the case 1 in the first state, the gravity center biasing device further includes two piezoresistors 35. Fig. 5 is a schematic structural diagram of another gravity center biasing device according to the present application, where two piezoresistors 35 are disposed corresponding to coils of two electromagnetic driving members 32, and the piezoresistors 35 are connected in parallel to two ends of the coils.

For example, when the housing 1 is in the second state, the mass 2 slides in the first direction. The mass 2 or the mass 2 together with the dielectric plate 34 is inserted between the two electrode plates 331 of the first plate capacitor, and the potential difference between the two electrode plates 331 of the first plate capacitor gradually increases, so that the attraction force of the first electromagnetic driving member to the mass 2 gradually decreases. The potential difference between the two electrode plates 331 of the second plate capacitor gradually increases, so that the attraction force of the second electromagnetic driving member to the mass 2 gradually increases.

Wherein the voltage across the varistor 35 gradually increases when the potential difference between the two electrode plates 331 of the second plate capacitor gradually increases, and the current does not pass through the coil of the second electromagnetic driver in parallel therewith when increasing to its nominal voltage. Thereby releasing the suction of the second electromagnetic driving member 32 to the mass 2. While the first electromagnetic drive still has a suction force in the first direction on the mass 2, so that the current bias state of the mass 2 is maintained. Only when the housing 1 is switched from the second state to the first state, the mass block 2 slides in the second direction, and when the voltage across the piezoresistor 35 is restored to be lower than the nominal voltage, the attraction force of the second electromagnetic driving member to the mass block 2 is restored.

It should be noted that, when the side of the housing 1 near the second end 22 is inclined downward in the gravity direction relative to the side near the first end 21, the action mechanism of the piezo-resistor 35 can be similarly deduced according to the above embodiment, and will not be described herein.

According to some embodiments of the application, as shown in fig. 1-5, when the housing 1 is in the first state, the mass 2 and the chute 11 are coincident with a center line perpendicular to the length of the chute 11, the mass 2 dividing the chute 11 into two chambers symmetrical with respect to said center line. Two elastic restoring elements 31 are respectively positioned in the two cavities. The fixed ends 321 of the two electromagnetic driving members 32 are symmetrical with respect to the center line. The two plate capacitors 33 are symmetrical with respect to the center line. The two electrode plates 331 of each plate capacitor 33 are respectively located at two sides of the chute 11.

Further, the gravity center biasing device further includes a rolling member 4. The rolling element 4 is arranged between the mass 2 and the chute 11. The rolling elements 4 serve to reduce the friction of the sliding of the mass 2 in the chute 11. For example, the rolling element 4 includes a plurality of balls, and the inner surface of the chute 11 is provided with a ball cage in which the balls are disposed. For another example, the rolling element 4 includes a plurality of rolling rings, and the plurality of rolling rings can be sleeved on the outer side of the mass 2 in a rolling manner. The cross section shape of the rolling ring is round.

According to some embodiments of the present application, as shown in fig. 2, the coil and the electrode plate 331 are respectively inserted into the case 1. Permanent magnets and dielectric plates 34 are inserted in the mass 2, respectively. Specifically, the housing 1 is provided with two first slots 12 and four second slots 13. The two coils of the two electromagnetic driving members 32 are respectively inserted into the two first slots 12 in a one-to-one correspondence manner. The four electrode plates 331 of the two plate capacitors 33 are respectively inserted into the four second slots 13 in a one-to-one correspondence manner. The mass block 2 is provided with two third slots 14 and a fourth slot 15, and two permanent magnets of the two electromagnetic driving pieces 32 are respectively inserted in the two third slots 14 in a one-to-one correspondence manner. The dielectric plate 34 is inserted into the fourth slot 15.
