[0031] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown in the figure, this application discloses a telescopic mechanism for a seat armrest, including a base plate 1 and two side plates 8. A drive plate 9 is disposed below the base plate 1, and an adjustment assembly 14 is disposed between the two side plates 8, with the adjustment assembly 14 located below the drive plate 9. The adjustment assembly 14 includes a bidirectional lead screw 141, two drive blocks 144, two sets of inclined plates 143, and two fixed blocks 142. The bidirectional lead screw 141 is rotatably connected between the two side plates 8. The two drive blocks 144 are threadedly connected to the outside of the bidirectional lead screw 141, allowing the drive blocks 144 to move by rotating the bidirectional lead screw 141. The two fixed blocks 142 are fixedly connected to the bottom of the drive plate 9. There are four sets of inclined plates 143, which are rotatably connected to the outside of the corresponding fixed blocks 142 and drive blocks 144. The inclined plates 143 rotate when the drive blocks 144 move, facilitating the position adjustment of the drive plate 9 above the fixed blocks 142.

[0032] like Figure 1 , Figure 2 as well as Figure 5 As shown, a cushion 2 is provided on one side of the backrest panel 4. The cushion 2 is filled with sponge, which makes it soft and provides better back support when the user leans on it. The softness of the sponge also enhances the comfort of use. The two armrests 7 are fitted with removable soft covers 6 to improve comfort when the hands are placed on them. The two side panels 8 are fixedly connected to the bottom of the base plate 1. Multiple vertical grooves 12 are provided between the two side panels 8 and the base plate 1. Vertical rods 5 are slidably embedded in the grooves 12. The tops of the vertical rods 5 are... Two armrest supports 7 are fixedly connected. They slide inside the vertical groove 12 via a vertical rod 5, ensuring that the armrest supports 7 can move stably after the vertical rod 5 moves. A backrest board 4 is fixedly connected to the rear side of the base plate 1. A pillow 3 is fixedly connected to the top of the backrest board 4. The pillow 3 can support the neck during use, further improving the overall comfort. Two support frames 10 are fixedly connected to the bottom of the base plate 1. The two support frames 10 are arranged in a U-shape. A connecting rod 15 is fixedly connected between the two support frames 10. The support frames 10 can provide support and are reinforced by the connecting rod 15.

[0033] like Figures 2-3 As shown, each of the multiple vertical slots 12 has a through slot 11 on its inner side. Each of the multiple through slots 11 has a connecting block 16 slidably connected inside. The multiple connecting blocks 16 are fixedly connected to the opposite side of the drive plate 9 and the vertical rod 5. By setting the connecting blocks 16 to slide inside the through slots 11, the connecting blocks 16 connect the vertical rod 5 and the drive plate 9. When the connecting blocks 16 slide, the vertical rod 5 and the drive plate 9 can be driven to move synchronously. The drive plate 9 is slidably connected to the outside of the two support frames 10, which facilitates the stability of the drive plate 9 when it moves.

[0034] like Figure 2 and Figure 4 As shown, one of the side plates 8 is provided with a rotating handle 13. One end of the rotating handle 13 is installed inside the side plate 8 and extends outward to be fixedly connected to one end of the bidirectional lead screw 141. The rotating handle 13 facilitates the rotation of the bidirectional lead screw 141.

[0035] The working principle of the telescopic mechanism of the seat armrest in this embodiment is as follows: When using the seat, the height of the armrest support 7 needs to be adjusted according to the needs of people of different heights. Rotating the handle 13 drives the bidirectional lead screw 141 to rotate. The bidirectional lead screw 141 then moves the drive block 144. Under the relative movement of the drive block 144, the inclined plate 143 can be rotated, driving the fixed block 142 and the upper drive plate 9 to move. After the drive plate 9 moves, the vertical rod 5 can be moved through the connecting block 16. After the vertical rod 5 moves, the position of the armrest support 7 can be adjusted to a suitable height for people of different heights. This allows for adjustments to be made for people of different heights, greatly improving the comfort during use. At the same time, the soft cover 6 and the backrest 2 further enhance the comfort.
