Copper bar protection structure, battery pack and electric vehicle

The invention discloses a copper bar protection structure which comprises an upper shell and a lower shell which are in butt joint with each other, the butt joint faces of the upper shell and the lower shell are each provided with a containing groove, the two containing grooves form a copper bar containing space, phase-change material layers are laid on the inner walls of the containing grooves, and when the copper bar accommodating space accommodates a copper bar, the copper bar is wrapped by the phase-change material layers. According to the copper bar protection structure, the copper bar containing space is designed between the upper shell and the lower shell which are in butt joint, the phase-change material layers are laid on the inner walls, then the copper bar is wrapped, and the copper bar protection structure achieves the effect of cooling the copper bar while achieving installation protection of the copper bar. The invention further provides a battery pack and an electric vehicle. 本发明公开一种铜排保护结构，包括相互
