Description

Technical Field

[0001] The utility model relates to the field of battery pack assembly, in particular to a new energy lithium battery pack assembly structure. Background Art

[0002] Battery packs are divided into series and parallel. Parallel battery packs require that each battery has the same voltage, and the output voltage is equal to the voltage of one battery. Parallel battery packs can provide stronger current. The battery pack PACK assembly structure mainly assembles most batteries in the same sealed shell.

[0003] For example, the utility model with the publication (announcement) number: CN212434776U discloses a heat dissipation assembly structure for a battery pack, including a shell with an opening at the top and a cover plate hinged on the shell opening, the front side of the inner wall of the shell is slidably connected with an L-shaped clamp plate 1, and the rear side of the inner wall of the shell is slidably connected with an L-shaped clamp plate 2, the surfaces of the L-shaped clamp plate 1 and the L-shaped clamp plate 2 are both provided with heat dissipation holes, and the left and right sides of the shell are provided with movable components, and the rotation of the movable components will drive the L-shaped clamp plate 1 and the L-shaped clamp plate 2 to move, so as to adjust the internal space of the shell and clamp and fix the battery pack. The utility model realizes the ability to simply and quickly change the size of the internal space of the shell through the cooperation of the above-mentioned structures, which is convenient for clamping and fixing battery packs of different lengths, and the operation is simple and convenient, and the air circulation speed inside the shell is increased by setting the inlet fan and the outlet fan, which is convenient for heat dissipation of the battery pack.
