Description

Technical Field

[0001] The utility model relates to the technical field of battery management, and more specifically to a BMS bracket. Background Art

[0002] The BMS battery system is commonly known as a battery nanny or battery butler. Its main function is to intelligently manage and maintain each battery unit, monitor the battery status, prevent the battery from overcharging and over-discharging, and extend the battery life. A bracket structure is required when installing and positioning the BMS battery system.

[0003] In the prior art, a patent document with publication number CN219476771U provides a bracket structure for BMS, which fixes the BMS body by passing bolts through a first fixing hole. A plurality of elastic clamping and fixing arms are arranged on both sides of the bracket body, so that the BMS can be clamped when external force is removed, thereby reducing the overall cost of the bracket structure and increasing the stability of the structure.

[0004] Although the device has many beneficial effects, the following problems still exist: during the use of the device, the BMS needs to be fixed with bolts, and it is not convenient to disassemble and remove the BMS when replacing or repairing the BMS; during use, the wires of the BMS are placed randomly, which makes it difficult for staff to distinguish them, and needs to be improved. In view of this, we propose a BMS bracket. Utility Model Content

The movement of the moving block 303 causes the first connecting rod 305 hinged to the moving block 303 to rotate, thereby driving the pressing plate 307 hinged to the first connecting rod 305 to move downward to press the BMS body 5. The slider 315 slidably connected to the slide groove 201 makes the pressure plate 307 move up and down more stably, and the wires connected to the BMS body 5 are arranged. The tip of the cable tie 405 passes through the hole in the locking part 404, and the one-way tooth 406 locks the cable tie 405 in the locking part 404 in one direction, so as to fix the wires in order. The cable tie 405 is rotated counterclockwise to a suitable angle and stops. The spring 410 pulls the pawl 407 to make it stuck in the tooth gap of the ratchet 403, so that the cable tie 405 is fixed. When replacement or maintenance is needed, the handle 314 is rotated in the opposite direction, and the BMS body 5 can be removed after the pressure plate 307 moves up.
