Electric power steering controller assembly

Abstract

The invention discloses an electric power steering controller assembly. A motor power source plug connector and a sensor signal plug connector are integrally formed in an injection molding mode and installed on the front side wall of a cover plate; an automobile body power source plug connector and an automobile body signal plug connector are integrally formed in an injection molding mode and installed on the rear side wall of the cover plate; the motor power source plug connector is transversely arranged, and the sensor signal plug connector, the automobile body power source plug connector and the automobile body signal plug connector are vertically arranged; the height of the cover plate gradually decreases from the middle to the front and is kept unchanged from the middle to the rear; a positioning protrusion stretches into a positioning groove so that a bottom plate and the cover plate can be installed and positioned; an installing support is composed of a horizontal plate and a vertical plate located in the middle of the horizontal plate and vertically connected with the horizontal plate, and the bottom plate and the installing support are fastened together through three bolt and nut assemblies. The electric power steering controller assembly is compact in structure, the interference between wires is effectively eradicated when the assembly is assembled, and the electric power steering controller assembly is stable and reliable when being installed.

Description

technical field [0001] The invention relates to the technical field of electric power steering control systems, in particular to a power steering controller assembly with a mounting bracket, which belongs to a mechanical installation structure. Background technique [0002] The controller is an essential part of the electric power steering control system, which consists of a circuit board, a bottom plate, a cover plate and a connector. The cover plate 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 cover, and 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 signa...

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.
