Electronic control unit (ECU) mounting structure for automobile

Abstract

The invention discloses an electronic control unit (ECU) mounting structure for an automobile. The ECU mounting structure comprises an ECU bracket and an ECU, wherein the upper end and the lower end of the ECU are provided with two mounting support lugs with bolt holes respectively; the ECU bracket is L-shaped; the upper end of the ECU bracket has two bolt through holes, and a horizontal part at the lower end of the ECU bracket have two clamping holes; ECU sheaths are clamped in the clamping holes; and the two mounting support lugs at the upper end of the ECU are fixedly connected with the ECU bracket through the bolt holes and bolts for the bolt through holes, and the two mounting support lugs at the lower end of the ECU are clamped in the two ECU sheaths respectively. By the mounting structure, the friction and the abrasion between the ECU and the ECU bracket can be reduced, abnormal noise can be effectively reduced, requirements on the accuracy of the ECU bracket can be reduced, and the service life of the ECU can be prolonged.

Description

technical field [0001] The invention relates to an installation structure of automobile parts, in particular to an installation structure of an automobile ECU. Background technique [0002] The central electronic control unit ECU is an important part of the car, which monitors and controls the various circuit units on the car to perform related functions. In the car, the ECU is fixed and supported by the ECU bracket. The upper and lower ends of the ECU are respectively provided with two mounting lugs with bolt holes. The existing ECU bracket is I-shaped, and its upper and lower ends are respectively provided with two The installation method of the ECU is as follows: the four mounting lugs of the ECU are fixedly connected to the ECU bracket with bolts through the bolt holes and the bolt holes, and the ECU and the ECU bracket are rigidly connected, and there is a large friction And wear, it is easy to cause abnormal noise; at the same time, this installation method has high r...
