A small and compact automotive power steering controller assembly

Abstract

The invention discloses a small and compact automobile power steering controller assembly, in which a motor power supply connector and a sensor signal connector are integrally injection-molded and installed on the front side wall of a shield; The connectors are integrally injection molded and installed on the rear side wall of the shield; the motor power connector is placed horizontally, and the sensor signal connector, body power connector and body signal connector are placed vertically; the shield is from the middle to the front The height of the center gradually decreases, and the height from the middle to the rear remains unchanged; the positioning protrusion extends into the positioning groove to realize the installation and positioning of the bottom plate and the shield; the mounting bracket is composed of a horizontal plate, located in the middle of the horizontal plate and perpendicular to the horizontal plate It is composed of connected vertical plates, and the bottom plate and the mounting bracket are fastened together by three bolts and nuts. The compact structure effectively eliminates the inter-line interference during the assembly of the assembly, and the installation is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of electric power steering control systems, in particular to a combined structure of a power steering controller and a mounting bracket, which belongs to a mechanical mounting 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 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 c...

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.
