Preferably, the fixed end of the buffer shaft is detachably connected with the moving plate. The buffer shaft can be replaced according to the external environment, so that the application range of the device is enlarged.

Preferably, the anti-collision mechanism comprises a connecting plate, a group of mounting plates are arranged on one side face of the connecting plate, the mounting plates are arranged oppositely, and a plurality of anti-collision wheels are arranged between the mounting plates.

Preferably, the free end of the buffer shaft is detachably connected with the other side surface of the connecting plate.

Preferably, the anti-collision wheel is rotatably connected with the mounting plate.

Preferably, the anti-collision wheel is made of rubber structural members.

Preferably, the buffer shaft is a hydraulic telescopic shaft.

Compared with the prior art, the invention has the advantages that: the buffer device for the robot chassis is simple in structure, and the impact force of the buffer mechanism is reduced by the double buffer effect of the buffer mechanism, so that the problem that the robot is easy to topple and damage due to the impact force generated by the collision between the buffer mechanism and the obstacle in the moving process of the robot is solved.

The beneficial effects of other embodiments of the present application are:

1. when the magnetic part peer relatively generates repulsive force, the repulsive force is gradually increased when the device is impacted and the movable plate moves close to the fixed plate, so that the moving speed of the movable plate relative to the fixed plate can be gradually reduced, the larger the impact on the movable plate is, the closer the movable plate is to the fixed plate, the larger the repulsive force is, the stress state can be automatically adjusted according to the impact degree of the movable plate, and the movable plate has a good buffering effect on the impact on the movable plate.
