Elastic contact on end face of powder battery of full electric vehicle

Abstract

The invention discloses an elastic contact on the end face of a powder battery of a full electric vehicle. A moving contact (5) in a moving contact component penetrates through a central hole of a moving contact pedestal (4), a moving contact pressure head (5a) is integrally formed at the front end of the moving contact (5), and the front end of the moving contact pedestal (4) supports against the moving contact (5) through an embedded knuckle bearing (6); and a fixed contact component is located in front of the moving contact component and is composed of a fixed contact (8), a fixed contact pedestal (9), an end cap (10) and a spring (11), and the rear end of the fixed contact (8) is provided with a fixed contact pressure head (8a) matched with the moving contact pressure head (5a). By using the elastic contact, the contact end faces of the moving contact and the fixed contact can be kept to have a certain positive pressure, and the moving contact has a self-alignment function and can be automatically adapted to the position of the fixed contact, so that the mixing contact and the static contact are kept to be in good contact, the power transmission efficiency increased, the power transmission reliability is improved, and the condition of arcing or conduction interruption caused by the instant separation of the end faces of the moving contact and the fixed contact is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to an elastic contact on the end face of a power battery 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 ene...

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
