Disclosed is a vehicle body anti-collision structure, which is mounted within a vehicle body covering and used for buffering an impact force applied to a vehicle body (1), the structure comprising two buffering frames (41) capable of buffering the applied impact force and a connecting frame (42), wherein the connecting frame (42) is disposed at the bottom end of the vehicle body and fixed to a chassis (2) of the vehicle body, and the two buffering frames (41) are respectively disposed at the front end and rear end of the vehicle body and are fixed to both ends of the connecting frame (42). The above-mentioned vehicle body anti-collision structure is of an overall structure, such that when the buffering frames at the front and rear of the vehicle body are impacted, the impact force will be dispersed to the whole vehicle body anti-collision structure and the chassis, instead of being completely withstood by themselves, so that a greater impact force can be withstood, improving the safety of the vehicle body.
