[0016] (2) In the present invention, the sliding component is set to drive the conveyor belt to operate by a driving motor. The cooperation between the first slider on the stop block and the first slide rail on the bottom plate can, on the one hand, guide the movement of the stop block, and on the other hand, ensure the smoothness and stability of the movement of the stop block, which is convenient and practical.

[0017] (3) In the present invention, two second sliders are arranged at the bottom of the stop plate. Through the cooperation between the second sliders and the second slide rails, while guiding the movement of the stop plate, the stability and smoothness of the movement of the stop plate are also ensured.

By setting the armrest plate as a combination of an armrest part and a connection part, on the one hand, the stability of the overall movement of the armrest plate is ensured, and at the same time, the armrest part has an arc-shaped armrest surface, which conforms to ergonomics, can make the elbow placed on the armrest part more comfortable. At the same time, the control module can accurately adjust the position of the armrest plate, so that the armrest plate adapts to the position of the driver instead of the driver adapting to the position of the armrest plate, thereby ensuring the comfort of the driver, which is efficient and practical.

[0019] (5) In the present invention, a cover plate is arranged on the cup holder, and an adjustment component is used to control the opening and closing of the cup holder. Limit slide grooves are arranged on each side rod. The side sliders at both ends of the cover plate cooperate with the limit slide grooves. On the one hand, the movement of the cover plate can be limited and guided, and on the other hand, the stability and safety of the cover plate during movement can be ensured.

[0020] (6) In the present invention, the side rod is set as a straight rod part and an arc rod part. The straight slide groove on the straight rod part can drive the cover plate to slide in the horizontal direction, and the arc slide groove on the arc rod part can drive the cover plate to slide in the arc direction, which can effectively ensure the smoothness of the sliding of the side sliders on both sides of the cover plate on the sliding path, and at the same time ensure the stability of the cover plate during sliding, which is stable and practical.

[0021] (7) In the present invention, a side motor on the adjustment component drives a push rod to push upward. During the upward push of the push rod, the push rod drives a double-speed chain and a limit connecting rod on the double-speed chain to drive the cover plate to move. The cooperation between the double-speed chain and the limit slide rail ensures the stability of the sliding of the double-speed chain and also guides the sliding of the double-speed chain, and also avoids the double-speed chain from shifting during the sliding process, and can accurately and stably drive the cover plate to move up or down, which is stable and practical.

[0022] (8) By means of the cooperation between the lead screw and the threaded holes on the connecting block, while ensuring the stable movement of the push rod, the displacement amount of the upward or downward movement of the cover plate can also be accurately controlled, avoiding excessive movement or damage to the side slider or the limit chute of the cover plate, and ensuring the safety during the movement of the cover plate.

[0023] (9) By arranging an arc-shaped slide rail on the connecting plate, on the one hand, it can be smoothly connected with the limit slide rail to ensure the smoothness of the movement of the double-speed chain, and on the other hand, it also supports the double-speed chain during the movement of the double-speed chain, and at the same time avoids the deviation of the double-speed chain during the sliding process, which is safe and practical.
