Replacement method of buffer spring of battery module damping structure

Abstract

The invention discloses a replacement method of a buffer spring of a battery module damping structure. The method comprises the following steps: enabling a push pin to slide in a sliding rail so as toenable the push pin to drive a mounting shaft to compress a second spring and extend into an accommodating groove; then enabling a shelving plate to drive the power supply module to be separated fromthe buffer spring; after the shelving plate is separated from the buffer spring, enabling connecting strips to compress the first spring, and when the two connecting strips compress the first springs, the two clamping blocks are driven to be separated from the clamping grooves so that the two clamping blocks are separated from the interiors of the mounting grooves; and a buffer plate and the buffer spring on the buffer plate are replaced. Through the design of movable connection among the shelving plate, the buffer plate and the accommodating cavity, the buffer spring can be fatigued and damaged after being stressed for a long time, the buffer plate and the buffer spring can be conveniently and quickly replaced, when different battery modules are replaced and mounted, the buffer spring does not need to be replaced at the same time, and more cost is saved during replacement.

Description

[0001] This application is a divisional application of a patent with an application date of May 4, 2018, an application number of 2018104213096, and a patent title of "A New Energy Vehicle Battery Module Damping Structure". technical field [0002] The invention relates to the field of shock absorbing structures, in particular to a method for replacing a buffer spring of a shock absorbing structure of a battery module. Background technique [0003] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines, including fuel cell vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles. Its exhaust emissions are relatively low. According to incomplete statistics, there are more than 4 million liquefied petroleum gas vehicles and more than 1 million natural gas vehicles in the world. At present, most of the new energy vehicles on sale in the Chinese market are hybrid vehicles and pure electric vehicles. [0004] In the shock-absorbi...

Problems solved by technology

[0004] In the shock-absorbing structure technology currently used for new energy vehicle battery modules, most battery modules are shock-absorbed by installing buffer springs at the bottom of the housing, resulting in , The buffer spring will be fatigued and damaged if it is stressed for too long. Not only is it inconvenient to disassemble and replace, but also when replacing and installing different battery modules, it is necessary to drive the buffer spring to be replaced together, resulting in higher consumption costs. For this reason, we design A new energy vehicle battery module shock-absorbing structure and a method for replacing the buffer spring of the battery module shock-absorbing structure are proposed to solve the above problems
