Shell structure of automobile body control module (BCM)

Abstract

The invention provides a shell structure of an automobile body control module (BCM). The shell structure consists of an upper cover and a lower cover, wherein a circuit board is arranged between the upper cover and the lower cover; the upper cover is fixed on an automobile frame through a fixing support; the upper cover is in interference fit with the fixing support, thus connecting fastener components and assembly processes thereof are omitted; notches of electrical couplers on a shell achieve common mode through additionally arranging embedded lumps on a plastic mould, thereby meeting different circuit board assembly requirements; reinforcing ribs in the upper and lower covers can be used for enhancing the integrated intensity of the shell, reducing the shell deformation caused by high temperature, low temperature, vibration and impact, eliminating the resonance vibration brought by deformation, reducing the automobile noise, prolonging the service lives of the shell parts of the BCM, improving the reliability of electron components in the MCM and prolonging the service life of the BCM; drain holes are arranged in the shell and are used for preventing water accumulated in the shell from causing the function invalidity of the BCM; under the condition that a certain distance exists between an automobile body fixing point and a BCM placement position, through assembling different installing supports, the installation reliability of the BCM and an automobile body also can be ensured.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a mounting structure for automotive electronic equipment, in particular to a shell structure of an automotive body control module. Background technique [0002] Body Control Module (BCM for short) is widely used in the intelligent control of automobile body. [0003] The fixing method of the body control module in the car is often connected by bolts between the shell and the body. For the following two cases: [0004] For the different markets of the same model, the shape of the body control module (circuit system) does not change much due to the left and right hand controls or the difference between automatic and manual gears, and the placement and fixed position of the body control system in the car changes. [0005] For different models, due to the difference in the internal structure of the car, although the shape of the body control module (circuit system) does not change much, al...
