Moving contact component of power battery pack of full electric vehicle

Abstract

The invention discloses a moving contact component of a power battery pack of a full electric vehicle. The moving contact component comprises a sealing head (3), a moving contact seat (4), a moving contact (5) and a joint bearing (6), wherein the moving contact (5) adopts a columnar structure and penetrates through a center hole of the moving contact seat (4); a moving contact press head (5a) is integrally formed in the front end of the moving contact (5); the sealing head (3) is fixed between the rear end of the moving contact seat (4) and the moving contact (5); and the front end of the moving contact seat (4) and the moving contact (5) are supported through the embedded joint bearing (6). According to the moving contact component of the power battery pack of the full electric vehicle, by means of self-alignment function of the moving contact, the position of a static contact can be automatically adapted to, good contact between the moving contact and the static contact is guaranteed, so that not only are the power transmission efficiency and reliability improved, but also arc discharge or electric conduction interruption due to instantaneous separation of end faces of the moving contact and the static contact is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a dynamic contact assembly of a power battery pack on a pure electric vehicle. Background technique [0002] At present, new energy vehicles, especially pure electric vehicles, have gradually matured and entered the stage of test and demonstration operation. During the use of pure electric vehicles, electric energy must be supplemented. At present, there are two modes for electric energy supplementation for pure electric vehicles. One is to charge electric vehicles, which takes a long time, usually several hours; the other mode It is to replace the battery pack of the electric vehicle, that is, to replace the battery pack of the electric vehicle. First, the battery pack that has run out of power consumption is quickly replaced, and then the fully charged battery pack is quickly installed on the electric vehicle, so as to quickly replenish the electric energy...

AI Technical Summary

Problems solved by technology

[0003] When replacing the battery pack on the chassis of a car, because the moving contacts are installed on the battery pack and the static contacts are installed on the vehicle chassis, and there are various errors in different battery packs, the contacts can only transmit electricity through end contact. The contact area and contact vibration will affect the transmission efficiency, poor contact, and the instantaneous separation between the contact surfaces due to the vehicle running vibration is easy to arc and burn the contact
