Battery module bottom limiting mechanism of battery compartment

Abstract

The invention provides a battery module bottom limiting mechanism of a battery compartment. The battery module bottom limiting mechanism enables positioning of a battery module to be time-saving and labor-saving and ensures battery replacement efficiency, and comprises a lower groove in a bottom plate, a ferrule assembly and a press-spring mechanism assembly, the ferrule assembly comprises a ferrule shaft and a ferrule, the ferrule shaft comprises a middle bent protrusion, the ferrule is mounted in a linear section of the middle bent protrusion in a sleeved manner, and two ends of the ferruleshaft are connected at corresponding positions of the bottom plate in a welded manner respectively; the press-spring mechanism assembly comprises linear springs, spring limiting columns a limiting plate and limiting frame, the bottom of each spring limiting column is welded at the bottom of the lower groove, one linear spring is mounted on each spring limiting column in a sleeved manner, the lowerend of each linear spring is fixedly mounted at the bottom of the lower groove while the upper end of the same is fixedly mounted on the limiting plate, the lifting frame and the limiting plate are welded into a whole, and the limiting plate is provided with avoiding holes at positions corresponding to the spring limiting columns.

Description

technical field [0001] The invention relates to the technical field of battery compartment structures, in particular to a limit mechanism for the battery module bottom of the battery compartment. Background technique [0002] Existing battery compartments used in electric vehicles are time-consuming and labor-intensive when replacing battery modules, and many parts need to be disassembled, which affects the installation efficiency of battery replacement. The reason is that the limit of the battery module needs to be continuously adjusted, resulting in Interference occurs between adjacent battery modules and between the battery modules and the battery compartment casing, so a limiting mechanism that can quickly position the battery modules is needed. Contents of the invention [0003] In view of the above problems, the present invention provides a limit mechanism at the bottom of the battery module of the battery compartment, which saves time and labor for the positioning o...
