Power exchange device and installation method thereof

Abstract

The invention discloses a power exchange device and an installation method thereof. The battery replacement device includes a battery pack fixing seat, a locking mechanism and an electrical connector at the car body end. The battery pack holder is formed with a battery pack accommodation chamber for accommodating the battery pack, the battery pack is provided with locking shafts on both sides, and the locking mechanism is fixed on both sides of the battery pack accommodation chamber. The vehicle body electrical connector is disposed in the battery pack accommodating cavity, and the vehicle body electrical connector faces the battery terminal connector of the battery pack. Both the vehicle body electrical connector and the battery electrical connector have a plurality of corresponding poles. When the lock shaft reaches the locking point of the locking mechanism, the pole of the electric connector at the battery end abuts against the pole of the electric connector at the vehicle body end. After the battery pack is locked in place, the battery terminal electrical connector can be reliably electrically connected to the vehicle body terminal connector, which can improve the reliability and efficiency of battery exchange for electric vehicles using the battery exchange device.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a power exchange device and an installation method thereof. Background technique [0002] The existing battery pack installation methods of electric vehicles are generally divided into fixed type and replaceable type. The fixed 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 an active way, 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 holder to assemble a power exchange device, and the power exchange device is installed on the chassis of the electric vehicle together...

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.
