Anti-deformation structure of automobile battery box

By setting a pressure plate and an elastic drive component between the movable plate and the fixed plate of the car battery box, the relative rotation of the pressure plate consumes external force, which solves the problem of insufficient deformation resistance of the lower tray, improves the buffering and shock absorption effect, and prevents damage to the battery module.

AI Technical Summary

Technical Problem

In the existing technology, the lower tray of the automotive battery box is insufficient in terms of resistance to deformation, which makes the battery module easy to be damaged. In addition, the force transmission method in the buffering process is simple, mainly along the vertical direction, and lacks a flexible and versatile shock absorption structure.

Method used

An anti-deformation structure for an automotive battery box was designed. By setting a first pressure plate and a second pressure plate between a movable plate and a fixed plate and connecting them with an elastic drive component, the pressure plates rotate in opposite directions under the action of external force, generating friction to consume energy. Combined with traditional compression deformation, torsion is achieved to consume external force.

Benefits of technology

The lower tray has improved its resistance to deformation, and the friction force dissipates external forces to prevent damage to the battery module. It also enhances the buffering and shock absorption effect and prevents short circuits and thermal runaway caused by deformation.

Abstract

The utility model relates to new energy power battery technical field, concretely relates to an anti-deformation structure of automobile battery box, include: the lower tray of battery box, with the movable plate fixed connection of lower tray, the fixed plate for connecting the automobile chassis, the movable connection of fixed plate and movable plate, the first pressure plate of one end with fixed plate rotation is connected and mutually pastes the first pressure plate. The utility model discloses through setting up the first pressure plate and the second pressure plate between the movable plate and the fixed plate of mutual interval, and through the both ends of elastic drive part and the first pressure plate and the second pressure plate link to each other, makes elastic drive part rotate to drive or drive the first pressure plate and the second pressure plate and rotate in the opposite direction when being pressed, and then makes two pressure plates and movable plate and fixed plate rub, thereby realizing traditional compression deformation buffer, and also can produce torsion, further consume external force, play the effect of the buffer shock attenuation of lower tray.
