The invention provides a collision protecting device of a power battery pack body. The collision protecting device comprises a first mounting plate and a second mounting plate, wherein the first mounting plate is arranged above the second mounting plate, the second mounting plate slides along the lower surface of the first mounting plate, the first mounting plate is fixed on an auxiliary frame, and the second mounting plate is connected with a vehicle body bracket.The first mounting plate (namely upper mounting plate) is mainly used for forming a plane on the bottom of the vehicle, the second mounting plate (namely lower mounting plate) is mainly used for separating from a vehicle body after collision with a barrier, so a sliding rolling log is formed between the barrier and the whole vehicle, the whole vehicle slides relative to the barrier, and through the whole sliding and friction process, the direction of the impact force is changed continuously and the impact force is reduced.
