AI Technical Summary
Existing battery pack wiring harness fixing structures have a wide variety of components and high costs, resulting in low production efficiency. Furthermore, traditional fixing methods are prone to failure under mechanical durability conditions, affecting the stability and safety of signal transmission.
The box beam structure is adopted, and the mounting components are directly set on the main beam, including the limiting part and the transition cavity, which reduces the types and number of parts. The arc plate structure and one-piece molding design ensure that the wiring harness is firmly fixed in the battery pack.
This technology enables the wire harness to be securely fixed within the battery pack, improving production efficiency and structural reliability, simplifying assembly and maintenance processes, optimizing space utilization, and ensuring the stability and safety of signal transmission.
