Module box convenient to overhaul

Abstract

The invention relates to the technical field of electric automobiles, in particular to a module box convenient to overhaul. The module box comprises a top cover, a bottom plate, two first side plates and two second side plates; the top cover, the bottom plate, the first side plates and the second side plates can be combined into the complete module box; the top cover, the bottom plate, the first side plates and the second side plates are movably connected to form the module box; the bottom surface of the top cover is movably connected with a lithium battery module through a buckle assembly; a plurality of groups of limiting and damping assemblies are arranged at the edge, corresponding to the lithium battery module, of the top surface of the bottom plate; and the limiting and damping assemblies play a role in limiting and damping under the cooperation of the bottom plate, the first side plates and the second side plates. According to the module box of the invention, the top cover, the bottom plate, the first side plates and the second side plates are movably connected to form the module box, and the interior of the module box and the lithium battery module can be thoroughly overhauled during overhauling and dismounting, so that the overhauling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a module box which is convenient for maintenance. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream now. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metal state Lithium is rechargeable, and the fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996. Its safety, specific capacity, self-dischar...

AI Technical Summary

Problems solved by technology

[0003] At present, the battery pack for vehicles is a combination of many single lithium battery cells connected in parallel. The combined lithium battery modules are placed in the module box, and the module box plays the role of protecting the lithium battery module. Based on the current vigorous development of the electric vehicle industry, The output rate and utilization rate of battery packs are getting higher and higher. Correspondingly, the number of battery packs that need to be maintained is also increasing rapidly. Because the module box mainly plays the role of protecting lithium battery cells, and the use environment of automotive battery packs It is relatively harsh, so it has high requirements on its ability to resist external impacts. Usually, multiple studs are used to penetrate from multiple sides of the module box to fix the battery pack, and then multiple studs and a top cover are used to secure the top surface of the module box. The opening is closed, which is more integral and reliable, but when the battery pack needs to be maintained in the future, it will not only be cumbersome and time-consuming to disassemble the module box, but also because the battery pack and the module box are directly connected by studs, it is rigid This is not conducive to reducing the vibration of the battery pack during driving, thereby greatly reducing the service life of the battery pack, increasing the cost of use, and not conducive to the practice of the current environmental protection concept
