Electric vehicle controller with waterproof and moistureproof functions

Abstract

The invention relates to the technical field of electric vehicle controllers, and discloses an electric vehicle controller with waterproof and damp-proof functions. The electric vehicle controller comprises an inner shell and an outer shell, wherein the inner shell is located in the outer shell, a waterproof structure and a heat dissipation structure are arranged between the inner shell and the outer shell, and the waterproof structure comprises a socket, a screw block, a fixing bolt, a fixing plate, a wiring chamber, a rubber pad, a jack and a plug; the socket is arranged on the right side surface of the inner shell, the jack is formed in the outer shell surface on the right side of the socket, the fixing plate is installed on the outer shell surface on the right side of the jack throughthe fixing bolt, and the plug is arranged on the left side of the fixing plate. According to the invention, the fixing plate with the plug and the wiring chamber is fixed on the surface of the shell,the plug can be inserted into the socket to conduct electricity, the electricity is conducted to the electric vehicle through a wire at the same time, and water can be prevented from entering the controller in the inner shell during use. Meanwhile, the fixing plate is fixed to the surface of the outer shell through the fixing bolt, and the situation that the use is affected due to open circuit caused by falling of the plug can be avoided.

Description

technical field [0001] The invention relates to the technical field of electric vehicle controllers, in particular to an electric vehicle controller with waterproof and moisture-proof functions. Background technique [0002] At present, the electric vehicle controller is the core control device used to control the start, operation, advance and retreat, speed, stop and other electronic devices of the electric vehicle motor. It is like the brain of the electric vehicle and is an important part of the electric vehicle. Components, because the wire of the controller passes directly out of the shell to the outside, there is a gap between the position where it passes out and the shell, which may cause moisture to enter the interior, causing water to enter and damage the internal components. [0003] Patent No. CN201621038435.6 discloses a non-leakage connecting line electric vehicle controller, including the electric vehicle controller main body, the top of the shell is provided w...

Problems solved by technology

[0004] When realizing this technical solution, there are at least the following defects: 1. The wiring harness is connected through the socket, and the controller is used in the bumpy environment in the electric vehicle for a long time, so that the socket is relatively easy to fall off, resulting in a circuit break; 2. The wiring harness used is not waterproof, and the connectors of the wiring harness are easy to enter water, which will affect the use
