Power exchange device and installation method thereof

Abstract

The invention discloses a power exchange device and an installation method thereof. The power exchanged device comprises a battery pack fixing base, locking mechanisms and a vehicle body end electrical connector; a battery pack containing cavity used for containing a battery pack is formed in the battery pack fixing base, lock shafts are arranged on the two sides of the battery pack respectively,and the locking mechanisms are fixedly arranged on the two sides of the battery pack containing cavity respectively. The vehicle body end electrical connector faces a battery end connector of the battery pack. The vehicle body electrical connector and the battery end connector are both provided with corresponding poles. When the locking shafts reach locking points of the locking mechanisms, the poles of the battery end connectors are abutted against the poles of the vehicle end electrical connector. After the battery pack is locked to the right position, the battery end electrical connector can be reliably and electrically conected with the vehicle body end connector, and the reliability and power exchange efficiency of applying the power exchange device to performing power exchange on electric vehicles can be improved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a battery swapping device and an installation method thereof. Background technique [0002] The battery pack installation methods of existing electric vehicles are generally divided into fixed type and replaceable type, wherein the fixed type battery pack is generally fixed on the car, and the car is directly used as the charging object when charging. The replaceable battery pack is generally installed in a movable manner, and the battery pack can be removed at any time and replaced with a new battery pack. [0003] In the process of replacing a new battery pack, the locking and unlocking of the battery pack is involved. Generally speaking, lock shafts are installed on the left and right sides of the battery pack; the locking mechanism is fixed on the battery pack fixing base to assemble a power exchange device, and the power change device is installed on the chassis of the elec...

AI Technical Summary

Problems solved by technology

[0005] However, in the prior art, the locking mechanism and the electrical connection device are independently provided, and it is easy for the locking mechanism to lock the battery pack in place, but the reliable electrical connection between the battery pack and the electrical connection device cannot be realized. , or the battery pack and the electrical connection device can be electrically connected relatively reliably, but the battery pack cannot be locked in place

That is to say, it is difficult for the power exchange device in the prior art to realize the synchronous function of the locking mechanism and the electrical connection device, which easily affects the efficiency and reliability of the power exchange.
