Problems solved by technology

[0003]At present, the connection components on electric vehicles are basically planar connections, and the planar connectors mainly squeeze the working surfaces of the inner battery box and the outer battery box Pressed together, there is a flexible connection between the two without forming a rigid whole. When the external force generated by the bumping and inertial extrusion of the electric vehicle acts on the connecting components, relative motion or friction will occur between the planar connectors. In severe cases It will cause instant separation between the connectors, resulting in virtual connection. For high-voltage electrodes, it is easy to generate discharge phenomenon, causing the electrodes to burn, which seriously affects the normal operation of the vehicle.
Because there is no good dustproof and waterproof measures for plane connection, there will be dust or adhesive moisture between the connectors, and discharge may occur at any time, causing partial or overall burning of the connected components and affecting the normal operation of the entire vehicle
In addition, the existing planar connection mainly adopts a decentralized connection method, the installation size is large, and the relative position between the connection components is difficult to ensure, which brings certain difficulties to the processing and is not conducive to the standardization of production and installation.

Abstract

The invention discloses a connection method and structure for an inner battery box and an outer battery box. In the invention, the inner battery box (1) is connected with the outer battery box (2) in a drawer manner; an elastic limited seat generates pre-pressure to the inner battery box (1) between the front end of the inner battery box (1) and the outer battery box (2); and a bolt (4) on the inner battery box (1) is connected with a keyhole (5) in the outer battery box (2) in an inserting manner, so as to ensure no displacement of the relative positions of the inner battery box (1) and the outer battery box (2). The connection method and structure can improve the connection reliability between the inner battery box and the outer battery box, and avoid sudden breakaway and electric discharge to result in connector burning to affect the normal operation of a vehicle due to relative movement and friction between the inner battery box and the outer battery box.

Description

technical field [0001] The invention relates to a connection method and structure of an inner and outer box of a battery, and belongs to the technical field of battery box replacement for electric vehicles. Background technique [0002] The battery is the main power unit of the electric vehicle, and the reliability of the battery connection plays a vital role in the operation safety of the electric vehicle. The battery outer box is installed on the electric vehicle, and the battery pack is contained in the battery inner box. Both the battery inner box and the battery outer box are equipped with an electrical connection group, and the battery inner box and the battery outer box are connected through a connection assembly. Since the electric vehicle is a moving carrier, the bumps of the electric vehicle during the movement and the inertial extrusion of the electric vehicle during acceleration and braking will affect the reliability of the connection components between the bat...
