Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] Such as figure 1 As shown, a connection structure between a collection piece and a busbar includes a busbar 1 and a collection piece 2 . The head 21 of the acquisition chip 2 is connected to the busbar 1, and the tail end is connected to the FPC3. FPC is also a flexible circuit board. The connection structure of the acquisition chip and the busbar plus the FPC is used to collect the voltage of the battery in the power battery. The busbar 1 is connected to the positive and negative poles of the battery, and the FPC is provided with a voltage acquisition circuit. busbar 1, such as figure 2 As shown, a chip groove 11 is provided at the connection between the busbar 1 and the collecting chip 2 . The head 21 of the collection sheet 2 is stuck in the sheet slot 11 , and the head 21 of the collection sheet 2 is fixed and connected to the busbar 1 through...

Abstract

The invention discloses a processing method of an acquisition sheet and a busbar connecting structure, and the connecting structure. The connecting structure comprises a busbar and the acquisition sheet. And the busbar is provided with a sheet groove. And a head of the acquisition sheet is clamped in the sheet groove to form a clamping structure between the busbar and the acquisition sheet. And the busbar and the acquisition sheet are connected and fixed in the sheet groove through a riveting portion and a laser welding spot. And the riveting portion is formed in a way that a riveting column arranged in the sheet groove penetrates through a riveting hole arranged in the head of the acquisition sheet and then the riveting column is processed by adopting a hot riveting processing technology.And the laser welding spot is formed after laser welding is performed around a periphery of the riveting portion. Compared with the prior art, by using the method and the structure of the invention,the connecting structure is firm and the acquisition sheet is not easy to fall off.

Description

technical field [0001] The invention relates to a connection mechanism for connecting a collection piece of a voltage collection device and a busbar through a busbar. Background technique [0002] With the support of national strategies and the development of related industrial systems, the market for new energy passenger vehicles is gradually expanding under the support of policies and its environmental protection and energy saving features. More and more new energy vehicles have entered thousands of households. What follows is that the public pays more attention to the safety of new energy vehicles. [0003] The current new energy vehicles are pure electric vehicles. The biggest safety hazard of pure electric vehicles is battery fire and explosion. In many electric vehicle fire accidents, the low-voltage information collection failure of the module accounts for a large part. Low-voltage information collection is roughly divided into three categories: wiring harness, FPC, ...
