[0014] Preferably, the support frame includes a vertical plate and a bottom plate, and the reducer is fixed on the vertical plate.
[0015] By adopting the above technical solution, the reducer is fixed on the vertical plate and remains stationary, and the support frame bears the reducer.
[0016] Preferably, the slider 1 and the slider 3 are fixed above the vertical plate, and the slider 2 and the slider 4 are fixed below the vertical plate.
[0017] By adopting the above technical solution, the slider is kept stationary and the guide rail can slide through the slider.
[0018] Preferably, the base plate is fixed to the vehicle body.
[0019] By adopting the above technical solution, the weight borne by the support frame can be transferred to the vehicle body through the bottom plate.
[0020] Preferably, the load-bearing plate, the carrying box and the rack are parallel along the length direction.
[0021] By adopting the above technical solution, when the rack drives the load-bearing plate to move, and then drives the load-bearing box to slide back and forth, it can ensure that the force is balanced during the movement, the operation is smooth, and the friction is small.
[0022] Preferably, a detachable inspection panel is provided on the side of the carrying box close to the interior of the carriage.
[0023] By adopting the above technical solution, installation is facilitated, and when a fault occurs inside the carrying box, it can be repaired by removing the inspection panel, thereby reducing repair costs.
