Description

Technical Field

[0001] This utility model relates to the field of batteries, and in particular to a novel battery box. Background Technology

[0002] In the field of battery applications, the battery box, as a core component that carries and protects the battery and enables electrical connection between the battery and external devices, directly affects assembly efficiency, circuit connection stability, and ease of use. Currently available traditional battery boxes have significant limitations in structural layout and functional implementation:

[0003] On the one hand, traditional battery boxes often use screws or complex snap-fit ​​structures to connect the bottom box and cover. Assembly requires tools to operate one by one, which is not only cumbersome but also prone to problems such as stripped screws and misaligned snaps, resulting in low assembly efficiency and making it difficult to meet the high-efficiency assembly requirements of mass production scenarios. On the other hand, the structures used to install electrodes in traditional battery boxes are mostly closed slots or welded interfaces. The installation and replacement of electrode components require disassembling the entire box or performing welding operations, further increasing the difficulty of assembly and maintenance.

[0004] On the other hand, traditional battery boxes typically rely on external wires to connect the positive and negative terminals of different batteries when implementing series and parallel battery connections, and then lead the wires to external devices. This method not only requires additional cutting and tidying of a large number of wires, increasing material costs and wiring complexity, but may also lead to safety hazards such as poor contact and short circuits due to loose wire joints or damaged insulation. In addition, the presence of wires occupies internal space in the battery box, limiting the battery arrangement density and making it difficult to adapt to the needs of miniaturized and integrated devices.

[0005] As electronic devices evolve towards lighter weight and longer battery life, higher demands are placed on battery box assembly efficiency, space utilization, and circuit connection reliability. The shortcomings of traditional battery box structural design can no longer meet the current needs for efficient production and stable use. Therefore, there is an urgent need for a new battery box structure that can simplify the assembly process, facilitate battery series and parallel connections, and reduce reliance on wiring.
