New energy automobile transmission protection device with heat dissipation structures

Abstract

A new energy automobile transmission protection device with heat dissipation structures is disclosed in the invention, and comprises a main body and a connecting piece, the outer side of the main bodyis wrapped with an insulating layer, the outer side of the insulating layer is fixedly provided with a shell in a bonding and wrapping manner, the left side of the shell is connected with a rotatingshaft through a key, and the left side of the rotating shaft is connected with an elastic piece through a key; a spring is welded to the interior of the elastic piece, a connecting piece is welded andfixed to the upper end of the shell, a connecting hole is formed in the shell, a connecting bolt is arranged in the connecting hole in a wrapped mode, and a heat dissipation plate is embedded, weldedand fixed in the shell. According to the new energy automobile transmission protection device with the heat dissipation structures, the multiple heat dissipation structures are arranged for heat dissipation, and a water circulation system is arranged for cooling and heat dissipation through water heat absorption, so the heat dissipation effect is better; and the batteries of the new energy automobile are all battery packs, and when one battery of each battery pack is damaged and needs to be replaced, one battery can be independently detached from the battery pack to be replaced, so that the maintenance cost is lower.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a transmission protection device for new energy vehicles with a heat dissipation structure. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with New technology, new structure of the car, the new energy vehicle transmission protection device is used to protect the new energy vehicle motor, and at the same time can be placed to fix the new energy vehicle battery. [0003] At present, the battery protection devices of new energy vehicles on the market do not have multiple heat dissipation structures for heat dissipation, and the non-water circulation system uses water to absorb heat to cool down and dissipate...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a new energy vehicle transmission protection device with a heat dissipation structure, which solves the problem that the battery protection device of the new energy vehicle on the market does not have multiple heat dissipation structures for heat dissipation, and the water circulation system does not use water to absorb heat Cool down and dissipate heat, and the heat dissipation effect is relatively general. The batteries of new energy vehicles are all battery packs. When one of the batteries in the battery pack is damaged and needs to be replaced, it is difficult to remove a single battery from the battery pack for replacement. The cost of replacing the entire battery pack Higher, and there is no insulating layer inside the battery protection shell to wrap the battery, the problem of low safety
