Battery container locking system and installation method of electric vehicle

Abstract

The invention relates to battery container locking system and installation method of an electric vehicle. The battery container locking system comprises a battery container guiding and positioning device, a battery container pre-tightening device and a battery container locking device, wherein the battery container guiding and positioning device is used for guiding and positioning a battery container during the process of installing the battery container; the battery container pre-tightening device is used for tightly compressing the battery container so as to improve installation rigidity of the battery container; and the battery container locking device is used for locking and fixing the battery container in a battery box. In the invention, the battery container can be installed and locked quickly and efficiently, and the stable work of the battery container is ensured.

Description

technical field The invention relates to a battery box locking system for quick-change electric vehicles, belonging to the technical field of power battery devices for electric vehicles. Background technique As a representative of new energy vehicles, electric vehicles have received more and more attention due to their cleanliness and economy. However, due to the battery capacity and charging time, the development of electric vehicles is limited. In recent years, the combination of electric vehicle replacement stations combined with the concept of automatic quick-change equipment has ushered in the dawn of the development of electric vehicles. The concept of electric vehicle battery replacement is that when the battery of the electric vehicle is about to run out, the battery box of the battery swap station is removed and replaced with a fully charged battery box. The whole battery replacement process is completed under the action of the automatic battery replacement equipm...

AI Technical Summary

Problems solved by technology

The existing electric vehicle battery box loading and unloading structure such as CN200910142368.0, although a method for replacing the battery is proposed, and a lock mechanism driven by a motor and detected by a sensor is provided, but its disadvantage is that it does not provide a guiding and positioning structure, which makes the replacement The electric mechanism needs to accurately locate the vehicle position, which increases the complexity of the battery replacement equipment; the second disadvantage is that it does not have a mechanism with a pre-tightening function, which makes the installation rigidity of the battery box low, and it is easy to move against the vehicle body under the bumpy driving conditions of the electric vehicle. Vibration, increased noise, increased impact and wear of joints
