Manufacturing method of novel explosion-proof shell and novel explosion-proof shell

Abstract

The invention relates to a manufacturing method of a novel explosion-proof shell. The manufacturing method comprises the following steps that S1, the novel explosion-proof shell is manufactured by using aluminum, magnesium or high polymer materials as base materials, so that the weight of the novel explosion-proof shell is reduced; and S2, the inner surfaces of the base materials are pretreated and sprayed with polyurea to form an explosion-proof layer so as to realize the explosion-proof performance of the novel explosion-proof shell and meet the explosion-proof water pressure test requirement. The invention also relates to the novel explosion-proof shell. According to the manufacturing method, and the novel explosion-proof shell which is light in weight and can meet the explosion-proof design requirement can be prepared.

Description

technical field [0001] The invention relates to the field of electric vehicles, and more specifically, relates to a method for manufacturing a novel explosion-proof casing and a novel explosion-proof casing manufactured by the method. Background technique [0002] As the country continues to increase support for new energy electric vehicles and charging infrastructure, planning and deployment from top-level design, policy support, etc., electric vehicles are ushering in a period of rapid development. The safety of electric vehicles has also received increasing attention. In order to ensure the safety of electric vehicles, explosion-proof motors and explosion-proof motor control devices are usually used, and special explosion-proof housings are used to accommodate explosion-proof motors and explosion-proof motor control devices to achieve safety. [0003] In the prior art explosion-proof casing, in order to meet the standard requirements of explosion-proof design such as exp...

AI Technical Summary

Problems solved by technology

However, copper or iron is not only expensive but also heavy, thus causing the explosion-proof case to be too heavy.

However, light-weight magnesium-aluminum and other substrates are prone to sparks, and their strength and compression resistance are not enough, and they are also prone to deformation, so they cannot meet the needs of explosion-proof environments.
