battery module

Abstract

The present invention provides a battery module, the second fixed case of the battery module includes at least one guiding structure and at least one guiding hole. The guiding structure extends from the bottom plate of the second fixed case in an accommodating space. The guide hole is located on the bottom plate, and the positions of the guide hole and the guide structure correspond to each other. And the pins of the electrode sheet pass through the guide hole, extend along the guide structure, and are electrically connected to the connection pad of the circuit board. Therefore, the pins of the electrode sheet can be effectively guided, so that the free ends of the pins can be located on the connection pads of the circuit board. Through this design, in addition to omitting the wires in the prior art, the electrical connection structure and electrical connection procedures between the circuit board and multiple battery devices can be simplified, thereby reducing manufacturing costs and reducing the cost of assembling the battery module. working hours.

Description

technical field [0001] The invention relates to a battery module, in particular to a battery module with an electrical connection structure between a circuit board and a battery device. Background technique [0002] With the advancement of science and technology, transportation vehicles have progressed from using gasoline as fuel for automobiles and locomotives to using natural gas as fuel for automobiles and as the power supply for automobiles and locomotives to operate. Bicycles have traditionally been driven by human power. Used as power for the bicycle to operate. Of course, with the gradual reduction of fuel raw materials, rising prices, and the rise of environmental awareness, transportation tools including electric bicycles, electric locomotives, and gasoline-electric vehicles have been developed. [0003] However, with the development of transportation vehicles and the emphasis on electric transportation vehicles towards the green energy industry, battery modules th...

Problems solved by technology

[0006] However, in order to transmit the voltage of the battery device 110 by piercing or lap-welding the pins 113 of the electrode sheet 112 to the wire 130, a plurality of wires 130 and connectors 131 must be used to transmit the voltage of each battery device 110. Therefore, the cost of manufacturing is increased, and in assembly, these wires 130 must be sorted out and plugged between the connector 131 and another connector, which causes inconvenience in assembly and increases production time.

[0007] Especially when other wires (not shown) for connecting to the outside are included, the wires and wires in the entire battery module 100 will be more messy, and it will also cause difficulty in assembly
