A battery production and assembly system for new energy vehicles

Abstract

The invention discloses a battery production and assembly system for a new energy vehicle, comprising a battery box, a splint is arranged on both sides of the battery box, a top cover is located on the upper part of the battery box, and a top cover is arranged in the middle of both sides of the top cover. When the pull rod is squeezed, a threaded screw rod is fixed in the middle of the opposite side of the two splints, and the extrusion pull rod cooperates with the two threaded screw rods to clamp and fix the battery box. In the present invention, the extrusion rods are arranged on both sides of the top cover, so that the top cover is closed on the battery box, and the extrusion rods on both sides of the top cover tightly press and fit the two splints on the side ends of the battery box, and rotate and fix. The nut sleeve is rotated on the threaded screw rod until the fixed nut sleeve is screwed together to fix the lower end of the extrusion rod, so as to avoid the separation of the extrusion rod and the threaded screw rod. The entire installation process requires two nuts to be fixed. The entire battery unit can be combined, which is convenient and quick.

Description

technical field [0001] The invention belongs to the technical field of battery production for new energy vehicles, and in particular relates to a battery production and assembly system for new energy vehicles. Background technique [0002] With the rapid development of social economy, there are slight differences with the types of electric vehicles. In a pure electric vehicle equipped with only a battery, the role of the battery is the only power source for the vehicle drive system. When producing a battery for a new energy vehicle, it is necessary to assemble an independent battery, and a battery assembly fixture is used. For example, a new energy vehicle battery assembly fixture in the prior art includes a clamping shell, there are two clamping shells, a clamping screw is installed inside the clamping shell, and the clamping Both ends of the screw rod are provided with fixing bolts, the inner sides of the two clamping shells are provided with insulating rubber sleeves, an...

AI Technical Summary

Problems solved by technology

There are many defects in the similar battery production and assembly technology: for example, when the existing technology assembles and installs the battery pack, in order to fix the two splints to the battery box, four threaded screw rods are generally used to penetrate the battery box, and nuts are used to fix the battery box. Combining and fixing, the operation is cumbersome, and there are certain safety hazards in the four threaded screw rods penetrating the battery box, and it is also prone to the problem of battery board detachment or battery detachment, and the friction between the battery and the external contact plate in the prior art It is difficult to achieve the best configuration, and because the battery cannot withstand too much pressure, there is also a risk of unsafety when the battery receives external stress from contact with foreign objects
