AI Technical Summary

Technical Problem

In traditional battery collection modules, under vibration or impact conditions, the welding points between the shunt and the PCB are prone to cracking, the weak areas of the PCB are prone to deformation, and assembly is difficult, resulting in low PCB utilization.

Method used

Support parts are provided on the shell, and the spacing between the support parts is smaller than the thickness of the diverter. The elastic deformation of the shell is used to provide pre-pressure to offset the external impact force. The support parts directly fix the diverter instead of the PCB board, eliminating the risk of solder cracking and weak areas of the PCB.

Benefits of technology

It avoids the risk of solder cracking and breakage of weak parts of PCB, improves the utilization rate of PCB board and simplifies the assembly process.

Abstract

The utility model provides a battery acquisition module, which comprises a first shell, a second shell, a shunt and a PCB (printed circuit board), the shunt and the PCB are sequentially assembled between the first shell and the second shell, the shunt comprises a shunt body and a connecting part, and the PCB is fixed on one surface of the shunt body through soldering tin; the connecting part is exposed to be connected with a vehicle body; supporting parts extend out of the tops of the opposite side edges on the first shell and the tops of the opposite side edges on the second shell which are assembled on the two surfaces of the flow divider; the supporting part located on the first shell and the supporting part located on the second shell are matched with each other in position. The distance between the supporting parts matched with each other in position is smaller than the thickness of the flow divider; at least one of the first shell and the second shell is of an elastic structure; the first shell and the second shell are tightly fixed to the flow divider through the supporting part, so that at least any one of the first shell and the second shell is deformed, pre-pressure is provided, and the pre-pressure is used for being converted into supporting force under the working condition of vibration or impact so as to counteract impact of external force on soldering tin and the PCB.
