Embodiment Construction

[0018] In the following, the present invention will be further explained through the embodiments and the accompanying drawings:

[0019] Combine Figure 1-Figure 5 The rectangular box type electric power steering controller shown is mainly composed of PCB board 1, base 2, cover 3, sensor signal connector 4, motor power connector 5, body signal connector 6 and body power connector Composition of 7 pieces.

[0020] Both the base 2 and the cover 3 are made of aluminum alloy by injection molding, and a downwardly extending side wall is provided along the circumferential edge of the cover 3, which together with the base 2 forms a rectangular controller housing. The PCB board 1 is installed on the base 2 and is located in the controller housing. The sensor signal connector 4 and the motor power connector 5 are integrally injection molded, and are installed on the front side wall of the cover 3. The body signal connector 6 and the body power connector 7 are integrally molded by injectio...

Abstract

The invention discloses a rectangular case type electric power-assisted steering controller which comprises a PCB (Printed Circuit Board), a base and a cover board, wherein a conical support column and a heat conducting seat are integrally formed on the base; the PCB is arranged on the conical support column, is positioned through two positioning columns penetrating through the PCB, and is then fixed on the heat conducting seat by combining with screws; the base and the cover board are pressed together; installation bulges are inserted into corresponding installation notches; the conical support column is positioned in the cover board and enables the cover board and the base to be fastened tighter and tighter; four circular columns which are in rectangular distribution and extend upwards are integrally formed on the base; and the back side of the base is provided with four thread installation blind holes corresponding to the four circular columns in position. The structure effectively avoids the problem of unfirm connection between the base and the cover board as well as between the PCB and the base after installation and effectively avoids the problem of overhigh local temperature of the PCB, and has a dustproof effect.

Description

Technical field [0001] The invention relates to an electric power steering controller for automobiles, and belongs to the technical field of mechanical structures. Background technique [0002] The electric power steering controller is an indispensable part of the electric power steering control system, which consists of a PCB board, a base, a cover, and connectors. The cover plate and the base jointly enclose a controller housing, and the PCB board is installed on the base and located in the controller housing. There are a total of four connectors, namely the motor power connector, the sensor signal connector, the body power connector and the body signal connector. The four connectors are all installed on the side wall of the cover. [0003] The base and the cover are fixed together by press-fitting. In the actual production and use process, the press-fitting is not tight occasionally after the press-fitting of the base and the cover, the installation between the PCB board and th...
