Novel electric vehicle controller structure

Abstract

The invention relates to a novel electric vehicle controller structure which comprises a shell. A circuit board is arranged in the shell, a rear end cover is fixedly connected with one end of the shell, a front end cover is fixedly connected with the other end of the shell, and one end of a pin insertion base is connected with the front end cover in an inserted mode and fixed through a fastening plate. An open hole is further formed in the shell, and a wiring unit is arranged on the open hole and connected with the circuit board in the shell. The novel electric vehicle controller structure is simple in structure and convenient to install; the waterproof sealing performance of a controller is improved through the fact that a sealing ring is embedded in the front end cover in a connected mode, and the stability of the pin insertion base on the front end cover is guaranteed through the installation of the fastening plate; meanwhile, the circuit board in the shell is connected with a wiring column in a wound mode, convenience is brought to testing and maintaining, and the structure mode that function wires of the circuit board are originally and directly led out is further avoided.

Description

technical field [0001] The invention relates to a controller, in particular to a novel electric vehicle controller structure. Background technique [0002] The electric vehicle controller is the core control device used to control the start, operation, advance and retreat, speed, stop of the electric vehicle motor and other electronic devices of the electric vehicle. It is an important part of the electric vehicle. As the central control part of the electric vehicle, it also It needs to have good waterproof, shockproof and heat dissipation performance. If the sealing is not good, the electric vehicle controller will get water, which will easily damage the circuit board components, which will cause the controller to work abnormally and cause the operation to malfunction. At present, the existing controller structure adopts the way that each function line is directly led out. One end of each lead-out line is welded on the integrated circuit board, and the other end is conn...

[0002] The electric vehicle controller is the core control device used to control the start, operation, advance and retreat, speed, stop of the electric vehicle motor and other electronic devices of the electric vehicle. It is an important part of the electric vehicle. As the central control part of the electric vehicle, it also It needs to have good waterproof, shockproof and heat dissipation performance. If the sealing is not good, the electric vehicle controller will get water, which will easily damage the circuit board components, which will cause the controller to work abnormally and cause the operation to malfunction.

At present, the existing controller structure adopts the way that each function line is directly led out. One end of each lead-out line is welded on the integrated circuit board, and the other end is connected to a functional connector. The plug-in of the function line is docked accordingly. This straight-line lead-out structure not only makes the controller time-consuming and laborious in the production process, but also affects the production efficiency. Offline leads to functional failure of electric vehicles
