At the same time, the supporting rod 203 rotates outward to open and compresses the shock absorber 208. The first spring 206 cooperates with the shock absorber 208 to buffer the chassis body 1, thereby protecting the battery in the battery compartment. When the obstacle collides with the second protection mechanism 3, the buffer roller 306 is arranged to first contact the obstacle and then rotate to unload the force. At the same time, the mounting frame 304 inclines to the side of the impacted buffer roller 306, and the third spring 305 above the impacted buffer roller 306 is compressed, and the other third spring 305 is stretched. As the vehicle advances, the obstacle contacts the buffer roller 306 in the middle of the mounting frame 304 and presses the mounting frame 304 upward, and the telescopic rod 301 and the second spring 303 are compressed. The second spring 303, the third spring 305 and the buffer roller 306 cooperate to buffer and protect the bottom of the chassis body 1, so that the battery in the chassis body 1 is not damaged. The first protection mechanism 2 and the second protection mechanism 3 are arranged to buffer and protect the chassis body 1 from multiple directions, thereby protecting the battery in the battery compartment and avoiding direct impact of the battery compartment in the chassis body 1 on the obstacle, thereby avoiding safety hazards.
