Problems solved by technology

[0004] The Chinese patent with the publication number CN101890901A discloses a quick-change mechanism for electric vehicle power batteries. The battery sliding mechanism used is connected by rolling balls arranged in the positioning seat to the bottom surface of the battery box. The contact between the balls and the bottom surface of the battery box is point contact. , the impact on the battery box during vehicle bumps will cause deformation of the battery box. The electrical connection interface and electrical connector used are also set on the rear end side of the battery box, and the insertion is completed when the battery box slides in. , the connector is also rigid, there will be arcing phenomenon during use, and the electrical connector will also bend and deform during the bumping process

Abstract

The invention provides a sliding bottom electricity-taking and self-locking electric bus battery quick-change pellet device. The electric bus battery quick-change tray device comprises a pellet and a locking and unlocking mechanism (3) mounted on the pellet. According to the invention, the battery box can be correctly positioned and reliably locked reasonably; the force is reasonably applied to the battery box; simple structure and simple and reasonable power wire splicing mode are obtained; and the arc discharge phenomenon can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of battery trays for electric vehicles, in particular to a tray capable of realizing quick battery replacement in a safe and reliable manner. technical background [0002] With the rapid development of the electric vehicle industry, its battery system technology is also developing in the direction of quick change and fast charging. For this reason, a power battery quick change system that is simple, reliable, reasonably designed and highly automated is required to complete the replacement of the power battery. The current electric vehicle power battery replacement system is limited by many aspects such as the connection mode of power and communication lines, the unreasonable structure of the locking and unlocking mechanism of the battery box, etc., resulting in the replacement of the power battery cannot be truly automated. For example, if the direction of the force applied to the positioning and clamping o...
