Problems solved by technology
[0003] The current new energy battery packs are fixed by using the upper and lower shells. Many fixing methods are fixed by welding. Although the fixing is simple, although the strength and sealing can be guaranteed by welding, it is difficult to disassemble and maintain. , directly through threaded connection, and the new energy battery pack is also directly fixed by bolts. This fixing method is prone to misalignment after the car is used bumpy, causing the liquid in the battery pack to leak.

The invention provides a battery pack outer frame, which includes two horizontal frames and two longitudinal frames opposite to each other. Both ends of each horizontal frame are chamfered and connecting grooves are disposed at the chamfers. The longitudinal frames are formed by engaging a first longitudinal frame and a second longitudinal frame. The ends of the first longitudinal frame and the second longitudinal frame away from the engagement ends are provided with engagement blocks connected to the connecting grooves. One side of each horizontal frame is provided with symmetric engagement grooves. A positioning through hole is disposed in the middle of each horizontal frame. Fastening connectors are disposed on the two sides of the positioning through hole. A side of each horizontal frame away from the engagement groove is provided with a connection plate A. Each connection plate A is provided with connection holes. The battery pack outer frame provided by the present invention is convenient to assemble and disassemble and has good sealing performance.
Description
technical field [0001] The invention relates to an automobile battery, in particular to an outer frame of a battery pack. Background technique [0002] Car battery packs are an essential part of cars and can be divided into traditional lead-acid batteries and maintenance-free batteries. Because the battery uses lead-calcium alloy as the grid, the amount of water decomposition generated during charging is small, and the amount of water evaporation is also low. In addition, the outer shell adopts a sealed structure, and the sulfuric acid gas released is also very little, so it is compared with traditional batteries. , has the advantages of no need to add any liquid, docking the pile head, and long power storage time. [0003] The current new energy battery packs are fixed by using the upper and lower shells. Many fixing methods are fixed by welding. Although the fixing is simple, although the strength and sealing can be guaranteed by welding, it is difficult to disassemble an...
