Technical Field

[0001] This utility model belongs to the field of BMS installation technology, and specifically relates to an adjustable BMS mounting bracket. Background Technology

[0002] With the booming development of new energy vehicles, the Battery Management System (BMS) is a key component in lithium battery applications such as electric vehicles and energy storage systems. Battery pack designs are becoming increasingly compact and complex, demanding higher requirements for space utilization, ease of assembly, and functional integration of structural components. However, different vehicle models and battery pack designs vary greatly. As the capacity requirements of battery systems increase, power battery systems typically consist of hundreds of cells. A single BMS motherboard cannot directly monitor all individual cells. Passenger vehicle battery pack systems often adopt a distributed BMS architecture (multiple acquisition boards, commonly known as "slave boards").

[0003] Existing BMS mounting brackets are often custom-developed, resulting in low versatility and poor assembly compatibility. In addition, BMS plug-ins are limited by space constraints, making subsequent maintenance and plug-in / removal difficult, which increases the complexity of the process to some extent.

Both sets of mounting plate assemblies are provided with guide grooves; the BMS board is equipped with guide components, which are slidably connected to the guide grooves; this enables the directional movement of the BMS board, facilitating subsequent maintenance and troubleshooting, and improving the efficiency of production assembly.

[0006] Furthermore, the mounting plate assembly includes a first mounting plate and a second mounting plate; the second mounting plate is fixedly mounted on the inner sidewall of the first mounting plate; a BMS plate is mounted on both the first and second mounting plates; the guide assembly includes a slide plate, bolts, and nut blocks; a slide plate is fixedly mounted on both the first and second mounting plates; the nut blocks are movably mounted within the slide plate. The bolts pass through the BMS plate and guide groove in sequence and are fixedly connected to the nut block.

[0007] Furthermore, the first mounting plate is Z-shaped and the second mounting plate is L-shaped, allowing for simple and stable staggered installation of the BMS board.

[0008] Furthermore, the guide components on the first mounting plate and the guide components on the second mounting plate are installed in opposite directions, which improves the ease of installation and disassembly of the upper and lower BMS boards.

[0009] Furthermore, a waist-shaped groove is provided on the side wall of the first mounting plate, which reduces the weight of the first mounting plate.

[0010] Furthermore, ribs are fixedly provided on the outer wall of the first mounting plate, which improves the strength and stability of the first mounting plate.

[0011] Furthermore, the ribs are triangular in shape.
