Fixing frame of lithium battery

Abstract

The invention discloses a fixing frame of a lithium battery. The fixing frame is a hollow cubical frame, and an accommodating chamber is formed in the middle part of the fixing frame and is used for containing a lithium battery cell and fixing the lithium battery cell in the fixing frame; a plurality of lock catches are arranged at the left and right sides of the fixing frame, and the lock catches at one side and the lock catches at the other side separately extend towards opposite directions in the depth direction of the fixing frame, so that the fixing frame and other fixing frames in the depth direction can be connected in a bidirectional locked manner; a pair of L-shaped bulges which are arranged oppositely are arranged on each of the upper and lower sides of the fixing frame, a square through hole is formed in each bulge, an accommodating groove is formed below each square through hole, and nuts are arranged in the accommodating grooves and are used for fixing a signal acquisition wire harness in the accommodating grooves, thereby realizing protecting of the signal acquisition wire harness.

Description

technical field [0001] The invention relates to a lithium battery fixing device, in particular to a lithium battery fixing frame and a battery module. Background technique [0002] Soft-pack lithium-ion power batteries have been widely used in the field of new energy pure electric vehicles and hybrid new energy vehicles. The application in this field has higher requirements for the use environment of lithium battery packs. The vehicle generates a lot of vibration during driving, so the lithium battery pack is required to be firm and not loose, the signal collection harness is not loose, and the signal collection is accurate. Therefore, how to ensure that the lithium battery pack is assembled firmly, adapts to the normal operation in the vehicle vibration environment, and at the same time satisfies fast production assembly and convenient on-site maintenance has become an important link in the lithium battery assembly design process. At present, most of the side baskets used ...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a lithium battery fixing frame, which effectively solves the problem of loose assembly of the existing soft-pack lithium battery, effectively solves the phenomenon that the soft-pack lithium battery pack module signal acquisition wire harness cannot be fixed and is easy to fall off, and significantly optimizes the soft-pack lithium battery assembly. The compactness of the module greatly improves the assembly process time of the soft pack lithium battery, thereby improving the service life and maintenance cycle of the soft pack lithium battery pack
