Specifically, the armrest 10 is rotatably connected with the backrest frame 20 between the open state and the folded state. The gear adjustment assembly is arranged between the armrest 10 and the backrest frame 20, and the gear adjustment assembly has at least one gear that limits the rotation angle of the armrest 10 between the open state and the folded state.

Therefore, according to the armrest assembly 100 of the embodiment of the present utility model, by setting the gear adjustment assembly between the armrest 10 and the backrest frame 20, the adjustable positions of the armrest assembly 100 are increased, and the armrest 10 can have multiple use positions. The use flexibility is improved to meet the needs of users of different heights.

It should be noted that, in related technologies, the armrest can only be switched between the open state and the folded state, and the use position is single, which cannot meet the needs of users of different heights. However, according to the armrest assembly 100 of the embodiment of the present invention, by providing a gear adjustment assembly between the armrest 10 and the backrest frame 20, the adjustable positions of the armrest 10 are increased, and the flexibility of use is improved.

Specifically, according to an embodiment of the present invention, the backrest frame 20 is provided with a fixed shaft 22, and the armrest 10 is provided with assembly holes 11 passing through both sides of the armrest 10. One end of the fixed shaft 22 is connected with the backrest frame 20, and the other end is Through the assembly hole 11 and connected with the nut 23 , the armrest 10 is rotatably mounted on the fixed shaft 22 . As shown in FIG. 1 , the back frame 20 is provided with a fixed shaft 22 , and one end of the fixed shaft 22 is connected with the back frame 20 . The lower end of the armrest 10 is provided with assembly holes 11 through both sides of the armrest 10, so that the armrest 10 can be inserted on the fixed shaft 22, and the other end of the fixed shaft 22 can be fixed with a nut 23.

Further, as shown in FIG. 1 , the armrest assembly 100 may further include a fixing plate 21 through which the fixing shaft 22 is mounted on the backrest frame 20 . That is, the fixed plate 21 is connected to the backrest frame 20 , and one end of the fixed shaft 22 is connected to the fixed plate 21 . In some specific implementations of the present invention, the armrest assembly 100 may further include a decorative cover 14 disposed on the other side of the assembly hole 11 . The cross-sectional shape of the decorative cover 14 is adapted to the cross-sectional shape of the assembly hole 11 , so that one end of the decorative cover 14 can be inserted into the assembly hole 11 and cover the assembly hole 11 and the components therein. The shapes of the mounting hole 11 and the decorative cover 14 can be various, for example, the shapes of the mounting hole 11 and the decorative cover 14 can be respectively formed as a circular hole and a circular cover (as shown in FIG. 1 ).

According to an embodiment of the present utility model, the gear adjustment assembly includes a support plate 12 , a tooth plate 30 and a locking block 40 . Specifically, the support plate 12 is disposed on the side of the armrest 10 adjacent to the back frame 20 , and the tooth plate 30 is rotatably mounted on the side of the support plate 12 adjacent to the back frame 20 relative to the support plate 12 . The tooth plate 30 is provided with a plurality of gear teeth 31 spaced along its circumference, and the tooth plate 30 is fixedly connected with one end of the fixed shaft 22 . The locking block 40 is pivotably installed on the support plate 12 adjacent to the position of the tooth plate 30, and the locking block 40 is provided with a limit tooth 41 adapted to the structure of the gear tooth 31, and the limit tooth 41 has a plurality of The position on the gear tooth 31 is switchable.

Thus, when the armrest 10 rotates, the support plate 12 can rotate synchronously with the armrest 10 . The support plate 12 and the tooth plate 30 rotate relatively, the locking block 40 on the support plate 12 rotates relative to the tooth plate 30, and after the handrail 10 rotates a certain angle, the limit tooth 41 meshes with the gear tooth 31, and the gear tooth 31 Clamping the limiting tooth 41 prevents the locking block 40 from continuing to rotate, thereby locking the gear adjustment assembly, restricting the rotational position of the support plate 12 and fixing the position of the armrest 10 . When the limit teeth 41 mesh with the gear teeth 31 at different positions on the tooth plate 30 respectively, the position of the locking block 40 relative to the tooth plate 30 changes. Correspondingly, the use position of the armrest 10 also changes, so that the armrest 10 can be switched between different positions.

It should be noted that when the gear tooth 31 is engaged with the limit tooth 41, pressing down on the armrest 10 will not disengage the gear tooth 31 from the limit tooth 41; The tooth 31 will be disengaged from the limiting tooth 41 . Therefore, when the armrest 10 is fixed at the use position and used, the position change will not occur due to a large downward force, and the use is relatively safe and reliable. According to an embodiment of the present invention, the tooth plate 30 is provided with a fixing hole 32 , and the tooth plate 30 is sheathed on one end of the fixed shaft 22 . Wherein, the fixing hole 32 may be formed as a square hole, one end of the fixing shaft 22 may be formed as a square column, and the other end of the fixing shaft 22 is provided with a screw thread 221 adapted to the nut 23 . A washer 24 can also be used to improve the fastening effect when installing the nut 23 .

In other words, after the tooth plate 30 is installed on the fixed shaft 22 , the position of the tooth plate 30 relative to the fixed shaft 22 does not change any more. During the rotation of the armrest 10 , the tooth plate 30 maintains the initial position without rotation, and the locking block 40 on the armrest 10 rotates relative to the tooth plate 30 , so that the rotation angle of the armrest 10 can be adjusted. In addition, the shapes of the fixing hole 32 and one end of the fixing shaft 22 can also be other structures capable of fixing and installing the gear plate 30 , for example, one end of the fixing shaft 22 can be a triangular prism, and the fixing hole 32 can be a triangular hole.

Thus, the tooth plate 30 can be fixedly connected with the backrest frame 20 through the prism structure at one end of the fixed shaft 22 . When the armrest 10 rotates, the tooth plate 30 and the backrest frame 20 do not move, the support plate 12 rotates relative to the tooth plate 30 , and makes the locking block 40 rotate relative to the tooth plate 30 . When the handrail 10 rotates to a certain angle, the gear tooth 31 of the tooth plate 30 meshes with the limit tooth 41 of the locking block 40, and the gear tooth 31 blocks the limit tooth 41 so that the locking block 40 cannot continue to rotate, and then The gear adjustment assembly is locked, the armrest 10 cannot continue to rotate, and the position of the armrest 10 is fixed.

The mounting structure of the locking block 40 on the support plate 12 can be various. Optionally, according to an embodiment of the utility model, the gear adjustment assembly further includes a fixed pin 15, and the fixed pin 15 is arranged on one side of the support plate 12. On the side, the locking block 40 is pivotably mounted on the fixing pin 15 . Further, the gear adjustment assembly further includes a torsion spring 50 , which is sheathed on the fixing pin 15 and abutted between the support plate 12 and the locking block 40 .

Specifically, when the armrest 10 is in the folded state, the limit teeth 41 on the locking block 40 and the gear teeth 31 on the tooth plate 30 are in a separated and non-engaged state, the torsion spring 50 is in a tightened state, and the locking block 40 The non-limiting tooth portion of the tooth plate abuts against the outer peripheral surface of the tooth plate 30, so that the locking block 40 is in a static state. When the armrest 10 is rotated from the folded state to the open state, the armrest 10 rotates relative to the tooth plate 30, and the support plate 12 rotates thereupon, so that the locking block 40 moves along the outer peripheral surface of the tooth plate 30, and the locking block 40 is twisted at the same time. The spring 50 pivots along the fixing pin 15 under the action of the torsion force of the spring 50, so that the torsion spring 50 is gradually relaxed. When the handrail 10 rotates to a certain angle so that the limit tooth 41 on the locking block 40 reaches the position of the gear tooth 31 on the tooth plate 30, the handrail can be stopped from turning. The limit teeth 41 on the locking block 40 are quickly engaged with the gear teeth 31 on the tooth plate 30 under the action of the torsion force of the torsion spring 50, the locking block 40 stops rotating, the gear adjustment assembly is locked, and the position of the armrest 10 can be adjusted. fixed.

In addition, when the armrest 10 is reset from the open state to the folded state, turning the armrest 10 can separate the gear tooth 31 on the tooth plate 30 from the limit tooth 41 on the locking block 40, and the gear adjustment assembly is unlocked, and the armrest 10 can be Continue to turn until armrest 10 is fully drawn in. During this process, the locking block 40 will move along the outer peripheral surface of the tooth plate 30, and the non-limiting tooth portion on the locking block 40 will abut against the outer peripheral surface of the tooth plate 30 to rotate, so that the torsion spring 50 is gradually retracted. Tight, and eventually return to the state when the armrest 10 is folded, and the locking block 40 also returns to the position when the armrest 10 is folded.

Further, according to an embodiment of the present invention, the tooth plate 30 is provided with a first limiting portion 33 and a second limiting portion 34 . The gear adjustment assembly further includes a limiting pin 13 , which is disposed on one side of the support plate 12 and located between the first limiting portion 33 and the second limiting portion 34 . Thus, when the limiting pin 13 is in contact with the first limiting portion 33, the armrest 10 can be in the limit position of the retraction, that is, the armrest 10 is in the non-use retracting position; when the limiting pin 13 is in contact with the second limiting portion 34 When in contact, the armrest 10 is in the lowest open position, ie the lowest use position of the armrest 10 .

Considering that the limit tooth 41 is to be switched at different positions on the gear tooth 31, and when the limit tooth 41 meshes with the gear tooth 31, the gear adjustment assembly is locked, and the limit tooth 41 will not be able to continue in the limit position. Position switching is performed on the tooth 41 , therefore, it is also necessary to provide an unlocking structure so that the position limiting tooth 41 can perform position switching on the gear tooth 31 . Optionally, according to an embodiment of the present utility model, the gear adjustment assembly further includes a sliding piece 60, and the sliding piece 60 is arranged between the tooth plate 30 and the support plate 12 and between the locking block 40 and the limit pin 13 . The sliding piece 60 is rotatable relative to the support plate 12 , and the outer peripheral surface of the tooth plate 30 is generally formed as an arc surface. The gear tooth 31 includes a high gear tooth 311 at the top and a low gear tooth 312 at the bottom. The arc length of the surface is equal to the arc length from the low gear tooth 312 to the first limiting portion 33 .

Specifically, when the armrest 10 rotates to a certain angle, the limit tooth 41 on the locking block 40 meshes with the high gear tooth 311 on the tooth plate 30, and under the action of the torsion force of the torsion spring 50, the locking block 40 is firmly locked. Block the high gear tooth 311, so that the armrest 10 is in the highest use position. When the force applied to the armrest 10 fails to overcome the torsion force of the torsion spring 50, the armrest 10 cannot continue to rotate.

If the handrail 10 is pressed down hard, when the applied force is greater than the torsion force of the torsion spring 50, the stop pin 13 on the support plate 12 can push the slide plate 60 to rotate, and the second end 62 of the slide plate 60 abuts against the lock. The stop block 40 is made to pivot along the fixed pin 15 against the torsion force of the torsion spring 50 , so that the limit tooth 41 and the high gear tooth 311 are disengaged. The limiting tooth 41 moves down along with the armrest 10 and reaches the position of the low gear tooth 312 and meshes with the low gear tooth 312 . The gear adjustment assembly is thus locked, and the armrest 10 is fixed at the lowest use position.

At this time, when the armrest 10 is rotated upward, the limit tooth 41 will disengage from the low gear tooth 312, so that the gear adjustment assembly is unlocked. The limit tooth 41 moves upward along with the handrail 10. When the limit tooth 41 moves to the last tooth position of the tooth plate 30, it stops applying an active force to the handrail 10. Under the action of the torsion force of 50, it is firmly stuck on the corresponding gear tooth 31, so that the armrest 10 is limited at this angular position, and the position switching of the limiting tooth 41 on the gear tooth 31 is realized. Rotate the armrest 10 upwards sequentially, and the limit teeth 41 can mesh with the gear teeth 31 in turn, so as to realize switching of the armrest 10 at different heights.

It can be understood that the number of fixed use positions of the handrail 10 depends on the number of gear positions on the gear teeth 31, when the limit tooth 41 meshes with a gear position on the gear teeth 31, the handrail 10 has a use position. Location. The specific number of gear teeth 31 can be reasonably adjusted according to actual needs. Specifically, the number of gear positions on the gear teeth 31 can be increased or decreased according to actual conditions to increase or decrease the use position of the armrest 10 .

Furthermore, according to an embodiment of the present utility model, a pin shaft 35 may also be provided on the gear plate 30, and an arc-shaped groove (not shown) adapted to its rotation track is provided on the sliding plate 60, and the pin shaft 35 Part of it extends into the arc groove. Further, the length of the arc-shaped groove is equal to the distance between the high gear tooth 311 and the low gear tooth 312 . Specifically, the pin shaft 35 is set such that the rotatable angle of the sliding piece 60 is equal to the arc corresponding to the arc groove, that is, equal to the arc corresponding to the high gear tooth 311 and the low gear tooth 312 .

Since the sliding piece 60 can push the tooth plate 30 to move, the limit tooth 41 can be completely switched from the high gear tooth 311 to the low gear tooth 312, thereby realizing the switching of the armrest 10 between the highest and lowest use positions. When the limit tooth 41 meshes with the low gear tooth 312, the pin shaft 35 will be at one end of the arc-shaped groove, and prevent the slide plate 60 from moving further, and then cannot continue to push the locking block 40, so that the limit tooth 41 can be aligned with the low gear. The gear teeth 312 are firmly engaged together. Wherein, the shape of the first end 61 of the sliding piece 60 can be adapted to the shape of the second stop portion 34, and the shape of the second end 62 of the sliding piece 60 can be adapted to the shape of the limiting tooth 41, so as to better Realize the pushing action of slide plate 60.

The use status of the armrest assembly 100 according to the embodiment of the present utility model will be described in detail below.

As shown in Figures 3 and 4, when the armrest 10 is in the limit position of the retraction, that is, when it is not in the retracted state, the limit pin 13 abuts against the first limit portion 33 on the tooth plate 30, and the gear plate 30 is in gear. The tooth 31 and the limiting tooth 41 of the locking block 40 are in a disengaged state. The torsion spring 50 is in a tightened state, and the non-limiting tooth portion of the locking block 40 abuts against the outer peripheral surface of the tooth plate 30 .

The armrest 10 is opened downward, the tooth plate 30 is fixed on the fixed shaft 22 and does not rotate, and the support plate 12 rotates around the fixed shaft 22 relative to the tooth plate 30 . At the same time, the locking block 40 moves along the outer peripheral surface of the tooth plate 30 , and pivots along the fixing pin 15 under the torsion force of the torsion spring 50 , and the torsion spring 50 gradually relaxes. When the handrail 10 rotates to a certain angle, the limit tooth 41 on the locking block 40 will mesh with the high gear tooth 311 on the gear plate 30 . The gear tooth 31 thus blocks the limiting tooth 41 so that the locking block 40 cannot continue to rotate, and at this moment the gear adjustment assembly is locked. The rotational position of the support plate 12 is restricted, and the position of the armrest 10 is fixed. As shown in Figures 5 and 6, the armrest 10 is fixed at the highest use position. The first end 61 of the sliding piece 60 abuts against the limiting pin 13 , and the second end 62 of the sliding piece 60 abuts against the locking block 40 .

At this time, if the handrail 10 is pressed down hard, when the applied force to the handrail 10 is greater than the torsion force of the torsion spring 50, the stop pin 13 continues to rotate with the support plate 12, and pushes the sliding plate 60 to rotate under the guidance of the pin shaft 35, And make the second end 62 of the sliding plate 60 push the locking block 40 , so that the locking block 40 can overcome the torsion force of the torsion spring 50 and pivot along the fixing pin 15 . Thus, the limit tooth 41 on the locking block 40 disengages from the high gear tooth 311 on the tooth plate 30 and moves down to the position of the low gear tooth 312, stops pressing down on the armrest 10, and the limit tooth on the locking block 40 Under the action of the torsion force of the torsion spring 50 , the gear teeth 41 will quickly mesh with the low gear teeth 312 on the gear plate 30 . As a result, the positions of the stop teeth 41 of the locking block 40 and the gear teeth 31 of the tooth plate 30 are switched, and the use position of the armrest 10 is thus changed, and the armrest 10 is fixed at the lowest use position, as shown in FIGS. 7 and 8 . Show. At this time, the limit pin 13 abuts against the second limit portion 34 on the tooth plate 30 and the first end 61 of the sliding piece 60, and the pin shaft 35 is located at one end of the arc-shaped groove, so that the sliding piece 60 cannot continue to move forward. Push the stop tooth 41 to move. Under the action of the torsion force of the torsion spring 50 , the limit tooth 41 and the low gear tooth 312 are firmly engaged together.

Turn the armrest 10 upwards, the locking block 40 rotates around the fixed pin 15, the limit tooth 41 will disengage from the low gear tooth 312, and the gear adjustment assembly is unlocked. The limit tooth 41 moves upward along with the handrail 10. When the limit tooth 41 moves to the last tooth position of the tooth plate 30, the limit tooth 41 on the locking block 40 is firmly locked under the torsion force of the torsion spring 50. On the corresponding gear teeth 31 , the armrest 10 is limited to this angular position, and the position switching of the gear teeth 41 on the gear teeth 31 is realized. Rotate the armrest 10 upwards sequentially, and the limit teeth 41 can mesh with the gear teeth 31 in turn, so as to realize switching of the armrest 10 at different heights.

When the armrest 10 is fixed at the highest use position, continue to rotate the armrest 10 upwards, the locking block 40 will rotate around the fixed pin 15, and then the limit tooth 41 and the gear tooth 31 will be disengaged. The gear adjustment assembly is thus unlocked, and the armrest 10 can continue to rotate until the armrest 10 is fully folded. During this process, the locking block 40 will move along the outer peripheral surface of the tooth plate 30, and the non-limiting tooth portion on the locking block 40 will abut against the outer peripheral surface of the tooth plate 30 to rotate, so that the torsion spring 50 is gradually retracted.
