Electric power-assisted steering controller steering controller housing assembly for preventing line interference

Abstract

The invention discloses an electric power-assisted steering controller steering controller housing assembly for preventing line interference. A motor power plug piece and a sensor signal plug piece are integrally injection-molded and are installed on the front side wall of a shield; a body power plug piece and a body signal plug piece are integrally injection-molded and are installed on the rear side wall of the shield; the motor power plug piece is transversely arranged, and the sensor signal plug piece, the body power plug piece and the body signal plug piece are vertically arranged; the height of the shield is gradually reduced from a central portion to a front portion and maintains unchanged from the central portion to a rear portion; the left and right middle branching lines of a controller housing are taken as boundaries, the motor power plug piece and the body power plug piece are disposed at a left side, and the sensor signal plug piece and the body signal plug piece are disposed at a right side; and a positioning projection extends into a positioning groove for realizing installation positioning between a base plate and the shield. The structure is compact, the size is quite small, and the line interference during assembly assembling is effectively eliminated.

Description

technical field [0001] The invention relates to an electric power steering controller shell assembly used for preventing interference between lines on an automobile, and belongs to the technical field of mechanical structures. Background technique [0002] The electric power steering controller is an essential part of the electric power steering control system, which consists of a circuit board, a bottom plate, a shield and a connector. The shield and the base plate together form a controller housing, and the circuit board is mounted on the base plate and located in the controller housing. The connectors are installed on the side wall of the shield, the connectors are all upright, and the entire controller housing is a standard square housing. [0003] The main problem of this structure is: due to the different sizes of the connectors, the size of the motor power connector is higher than that of the sensor signal connector, the body power connector and the body signal conne...

AI Technical Summary

Problems solved by technology

[0003] The main problem of this structure is: due to the different sizes of the connectors, the size of the motor power connector is higher than that of the sensor signal connector, the body power connector and the body signal connector. To meet the installation requirements of the motor power connector, the height should be increased correspondingly to match the connector, so that the entire controller appears bulky and brings a lot of trouble to the installation arrangement, especially in the case of limited space. Unable to install

At the same time, each connector is set separately. When the main engine factory assembles the assembly, it often produces inter-line interference, which affects the assembly efficiency.
