Embodiment Construction

[0019] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0020] combine figure 1 — Figure 5 The electric power steering controller with reliable assembly shown is mainly composed of PCB board 1, base 2, cover plate 3, sensor signal connector 4, motor power connector 5, body signal connector 6 and body power connector 7 components.

[0021] A side wall extending downward is provided along the peripheral edge of the cover plate 3 , and together with the base 2 forms a rectangular controller housing. The PCB board 1 is mounted on the base 2 and located in the controller housing. The sensor signal connector 4 and the motor power connector 5 are integrally injection molded and installed on the front side wall of the cover plate 3 . The body signal connector 6 and the body power connector 7 are integrally injection-molded and installed on the rear side wall of the cover plate 3 . Every two connectors are integr...

Abstract

The invention discloses a reliably-assembled electric power-assisted steering controller, comprising a PCB, a base and a cover plate. Tapered support columns and a right-trapezoid thermal conduction seat are integrally formed on the base, the PCB is arranged on the tapered support columns, positioned by penetrating through the positioning columns of the PCB and fixed to the thermal conduction seat by combining a bolt, the two positioning columns have different cross sections, installation notches are formed in the right and left sides of the base, installation bulges having equal number, corresponding position and matching size with the installation notches are arranged on the right and left sides of the cover plate, the base and the cover plate are pressed together, the installation bulges are inserted into the corresponding installation notches, the tapered support columns are positioned in the cover plate, the base and the cover plate are caused to be buckled tighter and tighter, and a plurality of stripy thermal conduction grooves extending right and left are arranged on the back of the base. By applying the structure, the problems that the base and the cover plate, and the PCB and the base shake slightly after being installed, and the temperature of part of the PCB is too high are solved.

Description

technical field [0001] The invention relates to an electric power steering controller used in automobiles, belonging 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 PCB board, a base, a cover plate and a connector. The cover plate and the base together form a controller housing, and the PCB board is mounted on the base and located in the controller housing. There are four connectors in total, namely motor power connector, sensor signal connector, vehicle body power connector and vehicle body signal connector, and the four connectors are all installed on the side wall of the cover plate. [0003] The base and the cover are fixed together by pressing. In the actual production and use process, the base and the cover are occasionally pressed and not tightened after being pressed. The installation between the PCB board and ...
