The adjustment block 16 is mounted on the mounting frame 11. The adjustment block 16 is made of rubber, and friction exists between the end wall of the adjustment block 16 and the side wall of the mounting frame 11. The armrest body 19 is mounted on the adjustment block 16. The armrest housing 21 is provided with a first adjustment groove 22, into which the armrest body 19 is inserted. The armrest body 19 is provided with a second adjustment groove 20. The armrest housing 21 is slidably connected to the armrest body 19.

The top wall of the slider 34 is provided with a placement groove 35. The connecting block 36 is fixedly connected to the groove wall of the placement groove 35.

[0073] In order to adjust the position of the armrest shell 21 on the armrest body 19 , a lock is further provided. The lock includes: a button block 24 , a bend 25 , a reset block 26 , and a first spring 28 .

[0074] The armrest housing 21 is provided with a button slot 23 that communicates with the first adjustment slot 22. A button block 24 is slidably connected within the button slot 23, and an elbow 25 is fixedly connected to the end wall of the button block 24. Two symmetrically positioned spring slots 27 are provided on the sidewalls of the button slot 23. One end of a first spring 28 is fixedly connected to the slot wall of the spring slot 27, and the other end of the first spring 28 is fixedly connected to a reset block 26. The reset block 26 has two symmetrically positioned spring slots that are fixedly connected to the button block 24 and slidably connected within the spring slots 27. A shift slot 42 is provided on the armrest body 19 and communicates with the second adjustment slot 20. Multiple shift slots 43 are evenly spaced along the slot wall of the second adjustment slot 20. The shift slot 42 and the second adjustment slot 20 are respectively connected to the multiple shift slots 43, and the elbow 25 extends into the shift slots 43.

[0075] A limiting component is provided for limiting the sliding position of the slider 34 , and the limiting component includes: a limiting block 38 , a guide column 41 , and a second spring 39 .

[0076] Two connecting grooves 37 are symmetrically positioned on the sidewall of the slider 34. Multiple stoppers 38 are symmetrically positioned and slideably connected within the connecting grooves 37. A guide hole 40 is defined on one sidewall of the stopper 38, and an arcuate surface 44 is defined on the other end of the stopper 38. The ends of the guide post 41 are inserted into the guide holes 40 on either side. The second spring 39 is sleeved onto the guide post 41, and the ends of the second spring 39 are fixedly connected to the stoppers 38 on either side.

[0077] Working or installation process:

[0078] Initial position: The elbow 25 is inserted into the second adjustment groove 20 and a portion of the elbow 25 extends into the shift groove 43. The groove wall of the shift groove 43 is in smooth contact with the outer wall of the elbow 25. The limit blocks 38 on both sides extend out of the connecting groove 37 and into the clamping grooves 32 on both sides. The arc surfaces 44 on the limit blocks 38 are in smooth contact with the clamping grooves 32. At this time, the second spring 39 is in a non-compressed state.

[0079] Insert the bolt into the fixing hole 12 and securely connect the mounting bracket 11 to the seat via the bolt. Align the threaded shaft 17 and the limiting shaft 18 on the adjusting rotary block 16 with the threaded hole 14 and the waist-shaped groove 15, respectively, and thread the threaded shaft 17 into the threaded hole 14. Install the adjusting rotary block 16 on the mounting bracket 11, and limit the limiting shaft 18 via the waist-shaped groove 15, so that the adjusting rotary block 16 can only tilt and rotate to a certain extent around the axis of the threaded hole 14. Since the adjusting rotary block 16 is made of rubber and there is friction between the end wall of the adjusting rotary block 16 and the mounting seat 13, the adjusting rotary block 16 will not rotate easily when not subjected to a large external force.

[0080] When the inclination angle of the armrest body 19 needs to be adjusted, the armrest body 19 is directly moved, and the armrest body 19 drives the adjustment block 16 to rotate, so that the inclination angle of the armrest pad 45 is adjusted;

[0081] When the position of the armrest pad 45 needs to be adjusted, the button block 24 is pressed, and the button block 24 drives the reset block 26 to slide in the spring groove 27 and squeeze the first spring 28. The first spring 28 is deformed under pressure, and the elbow 25 follows the button block 24 to move toward the shift groove 42, and the elbow 25 moves out of the gear groove 43. The groove wall of the gear groove 43 no longer limits the elbow 25, and the elbow 25 slides into the shift groove 42. While pinching the button block 24, the armrest shell 21 is pulled to move on the armrest body 19, thereby adjusting the length of the armrest shell 21 extending from the armrest body 19, and when the elbow 25 moves to a certain When the armrest is in the locked position, the button block 24 is released and no longer pressed. The button block 24 no longer drives the reset block 26 to press the first spring 28. The first spring 28 uses its own elastic potential energy to push the reset block 26 in the opposite direction. The reset block 26 drives the button block 24 to move away from the armrest body 19, and the button block 24 drives the elbow 25 to move away from the shift groove 42 until the elbow 25 moves into one of the gear grooves 43 again, and the groove wall of the gear groove 43 limits the elbow 25 again. At this time, the armrest housing 21 can no longer slide on the armrest body 19 and is fixed in a limited position.

[0082] The second spring 39 is pressed against the stop blocks 38 on both sides, so that the arc surface 44 on the stop blocks 38 moves out of the connecting groove 37 again and extends into the slot 32, and the side walls of the stop blocks 38 are limited to a certain extent by the slot walls of the slot 32.

[0083] By changing the tilt angle of the armrest body 19 , the extension length through the armrest shell 21 is adjusted, and the horizontal position of the armrest pad 45 is adjusted, thereby achieving multi-directional adjustment of the armrest pad 45 .

[0084] The above description is only an illustration of some preferred embodiments of the present disclosure and the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
