Lithium polymer battery pack with excellent safety performance

The utility model relates to the technical field of lithium polymer battery packs, in particular to a lithium polymer battery pack with excellent safety performance, which comprises a shell and a cover plate, a fixing component is arranged in the shell, the top end of the shell is in contact with the cover plate, a heat dissipation mechanism is arranged in the cover plate, a damping sleeve is arranged in the shell, and the damping sleeve is arranged in the shell. And a sliding rod is slidably connected into the damping sleeve, a spring is arranged on the outer side of the sliding rod, and a protection plate is fixedly connected to the end, away from the shell, of the sliding rod. By arranging the damping sleeve and the sliding rod, when the protection plate is stressed, the sliding rod is driven to move, the sliding rod moves in the damping sleeve, the force borne by the protection plate is consumed through friction, and the problems that when the protection plate protects a battery pack, external force is st
