In existing stepless adjustment handrails, one-way adjustment is generally performed, and the handrail can be reset only after reaching the vertical position. Moreover, the existing stepless adjustment handrails have problems such as complex structure, uneven adjustment, and easy wear. SUMMARY

[0015] The unlocking mechanism further comprises a pushing piece, the pushing piece is connected with the unlocking piece through a pull cable, and the pushing piece can drive the pushing piece through the pull cable;

[0019] Further, the pushing piece is rotatably arranged in the handrail, and the pushing piece comprises a pushing piece and a pressing plate fixedly connected with the pushing piece, the pull cable is connected on the pushing piece, and the pressing plate movably abuts against the first limiting block and the second limiting block respectively.

[0020] Further, the pushing piece is provided with a first spring, the elastic force of the first spring acts on the pushing piece, so that the pressing plate has a tendency to move in a direction of pressing the first limiting block and the second limiting block.

[0021] Further, a second spring is arranged between the first friction plate and the second friction plate, one end of the second spring is connected with the first friction plate, and the other end of the second spring is connected with the second friction plate.

[0022] The elastic force of the second spring makes the first friction plate and the second friction plate have a tendency to move close to each other.

For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0041] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0042] like Figures 1-7 As shown, an adjustable armrest assembly mainly includes: a mounting body 1, an armrest 2, a locking mechanism 3 and an unlocking mechanism 4. The locking mechanism 3 mainly includes: a first friction plate 31, a second friction plate 32 and a second spring 30. When the locking mechanism 3 is locked, it can limit the rotational freedom of the armrest 2; the unlocking mechanism 4 mainly includes an unlocking member 40, a push member 41, a cable 42 and a first spring 43. The unlocking mechanism 4 can unlock the locking mechanism 3, thereby releasing the rotation restriction of the locking mechanism 3 on the armrest 2, so that the armrest 2 can be adjusted 360 degrees steplessly.

[0043] like Figure 1 and Figure 7As shown, an armrest shaft 10 is provided on the mounting body 1. The mounting body 1 can facilitate the installation of the entire adjustable armrest assembly of this embodiment on the side of the car seat. The armrest shaft 10 is fixedly mounted on the mounting body 1, and in order to facilitate the installation of other components, a shell 11 is also fixed on the armrest shaft 10. The shell 11 is fixed to the slot on the armrest shaft 10 by a retaining spring, that is, the mounting body 1, the armrest shaft 10 and the shell 11 are fixedly connected.

[0044] A rotating base 20 is provided on the armrest 2, and the rotating base 20 is rotatably provided on the armrest shaft 10, that is, the armrest 2 is rotatably mounted on the armrest shaft 10 through the rotating base 20. When the armrest 2 is rotated and adjusted, the rotating base 20 rotates around the armrest shaft 10, that is, the armrest 2 rotates around the armrest shaft 10.

[0045] like Figures 4-5 As shown, the locking mechanism 3 has a locked state and an unlocked state. The locking mechanism 3 includes a first friction plate 31 and a second friction plate 32 that are movably connected. When the locking mechanism 3 is in the locked state, the first friction plate 31 and the second friction plate 32 abut against the rotating base 20, restricting the rotation of the armrest 2. When the locking mechanism 3 is switched to the unlocked state, the first friction plate 31 and the second friction plate 32 move toward each other and disengage from the rotating base 20, releasing the rotation restriction on the armrest 2. Specifically, the rotating base 20 has a curved inner wall 201. The first friction plate 31 and the second friction plate 32 both have a curved outer wall 313. When the locking mechanism 3 is switched to the locked state, the curved outer walls 313 of the first friction plate 31 and the second friction plate 32 abut against and rub against the curved inner wall 201 of the rotating base 20. The first friction plate 31 and the second friction plate 32 are preferably made of a wear-resistant material and are used to brake the rotating base 20.

[0046] Further specifically, the first friction plate 31 is provided with a first connecting piece 311 which is integrally arranged or fixedly connected with the first friction plate 31. The second friction plate 32 is provided with a second connecting piece 321 which is integrally arranged or fixedly connected with the second friction plate 32. The first connecting piece 311 and the second connecting piece 321 are rotatably connected through a hinge shaft. The first connecting piece 311 and the second connecting piece 321 are respectively located at one end of the first friction plate 31 and the second friction plate 32, and the other end of the two is respectively provided with a first limiting block 312 and a second limiting block 322, that is, the first friction plate 31 is provided with the first limiting block 312, and the second friction plate 32 is provided with the second limiting block 322. The pushing piece 41 is in movable abutment with the first limiting block 312 and the second limiting block 322 respectively. By extruding the first limiting block 312 and the second limiting block 322 through the pushing piece 41, the first friction plate 31 and the second friction plate 32 can be away from each other, and the two are abutted on the arc-shaped inner arm of the rotating base 20, so as to lock the rotating base 20, that is, to lock the handrail 2. The first friction plate 31 and the second friction plate 32 are provided with a second spring 30, one end of the second spring 30 is connected with the first friction plate 31, and the other end of the second spring 30 is connected with the second friction plate 32. The elastic force of the second spring 30 makes the first friction plate 31 and the second friction plate 32 have a tendency to approach each other. When the pushing piece 41 does not extrude the first limiting block 312 and the second limiting block 322, the second spring 30 pulls the first friction plate 31 and the second friction plate 32 to make the rotating base 20 recoverable, that is, the handrail 2 is rotatable and adjustable.

[0047] In use, when the locking mechanism 3 is switched to the unlocked state, the rotating base 20 can rotate 360° relative to the handrail shaft 10, so that the handrail 2 can be adjusted by 360 degrees, that is, it can be adjusted by 360 degrees steplessly. When the rotating base 20 rotates at any angle relative to the handrail shaft 10, the locking mechanism 3 is switched to the locked state, so that the handrail 2 is suspended at any angle.

[0048] As Figures 1-3 and in combination Figures 4-6The unlocking mechanism 4 includes an unlocking member 40 movably arranged on the armrest 2 and capable of driving the locking mechanism 3 to switch to the unlocking state. The unlocking mechanism 4 further includes a pushing member 41 connected with the unlocking member 40 through a cable 42 and capable of driving the pushing member 41 through the cable 42. The pushing member 41 is capable of driving the first friction plate 31 and the second friction plate 32 to move away from each other and abut against the rotating base 20. The pushing member 41 is rotatably arranged in the armrest 2 and includes a pushing piece 411 and a pressing plate 412 fixedly connected with the pushing piece 411. The cable 42 is connected with the pushing piece 411, and the pressing plate 412 movably abuts against the first limiting block 312 and the second limiting block 322, respectively. A first spring 43 is connected with the pushing piece 411 and exerts a force on the pushing piece 411 to make the pressing plate 412 have a tendency to move in a direction to press the first limiting block 312 and the second limiting block 322, i.e., the first spring 43 can ensure that, in a normal state, the pushing member 41 is pulled to make the pressing plate 412 press the first limiting block 312 and the second limiting block 322, so that the locking mechanism 3 is in the locking state and the structural stability of the armrest 2 is ensured. In order to save labor, the cable 42 can be combined with a plurality of movable pulleys and a fixed pulley to pass through the movable pulleys and the fixed pulley and then be connected with the pushing member 41, so that labor is saved when the unlocking member 40 is operated.

[0049] In use, in a normal state, the armrest 2 is suspended on the side of the seat of the vehicle, and at this time, the locking mechanism 3 is in the locking state, and the pressing plate 412 on the pushing member 41 presses the first limiting block 312 and the second limiting block 322 outward, so that the first friction plate 31 and the second friction plate 32 abut against the inner wall of the rotating base 20 to limit the rotation of the rotating base 20, i.e., the armrest 2 is locked. When it is necessary to rotate and adjust the armrest 2, the unlocking member 40 is pushed to make the pushing member 41 rotate through the cable 42, so that the pressing plate 412 on the pushing member 41 no longer presses the first limiting block 312 and the second limiting block 322 outward. Under the action of the pulling force of the second spring 30, the first friction plate 31 and the second friction plate 32 move inward to each other and are separated from the abutment against the rotating base 20, so that the rotating base 20 recovers the degree of freedom of rotation, i.e., the armrest 2 can be rotated and adjusted. When the adjustment of the armrest 2 is completed, the unlocking member 40 is pulled to make the pushing member 41 reversely rotate through the cable 42, so that the pushing member 41 again presses the first limiting block 312 and the second limiting block 322 outward, and the first friction plate 31 and the second friction plate 32 move away from each other and abut against the arc-shaped inner wall 201 of the rotating base 20, so that the armrest 2 is locked.

[0050] In the scheme, the armrest 2 can be rotated and adjusted in a 360-degree stepless manner in any direction, and after the adjustment, the armrest 2 can be suspended and locked at any angle. The overall structure is simple and stable.
