[0002] A battery pack is a battery system composed of multiple battery cells. A battery cell is the basic unit of a battery, and a battery pack is a system that connects multiple battery cells together to form a larger capacity or higher voltage system. The shell of a battery pack refers to the outer shell structure of the battery pack. Its main function is to protect the battery cells, cells or battery components inside the battery, while providing mechanical support and insulation. The existing shell structure for battery packs is to select batteries of appropriate specifications and install them in the battery pack shell. The positive and negative electrodes of the battery are connected to the positive and negative electrodes in the shell. During the installation process, the negative electrode of the battery will squeeze the spring to achieve installation and fixation. During the installation process, the spring is squeezed and easily bent. The bending of the spring on the negative electrode sheet will cause poor contact of the battery, thereby affecting the battery performance, and it is easy to cause the spring to lose elasticity, affecting the cycle life of the battery.
[0003] Therefore, it is necessary to design a battery pack housing structure with a positioning structure that can position the spring on the negative electrode sheet when it is squeezed to prevent the spring from bending and affecting the battery cycle life. Utility Model Content
