Vehicle body controller shell

Abstract

The utility model relates to the technical field of vehicle-mounted electrical equipment, in particular to a vehicle body controller shell which comprises an upper shell body and a lower shell body, receding holes corresponding to circuit board pins are formed in the upper shell body, and a plurality of limiting ribs are arranged on the inner side of the lower shell body at intervals in the circumferential direction of the lower shell body. The limiting ribs are used for limiting the circuit board placed in the lower shell and preventing the circuit board from moving relative to the lower shell. Through the arrangement of the limiting ribs, the circuit board is ensured to be fixed relative to the lower shell after being mounted in the lower shell, so that when the upper shell is covered, the abdicating holes in the upper shell can be ensured to be aligned with the corresponding circuit board pins, and the problem that the circuit board pins are crushed by the upper shell due to the fact that the abdicating holes are not aligned with the circuit board pins is effectively prevented.

Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicle-mounted electrical equipment, and in particular to a vehicle body controller housing. Background Art

[0002] The body control module (BCM) is one of the important components of a car. It is generally used to control the vehicle's electric windows, electric rearview mirrors, air conditioning, headlights, turn signals, defrost devices, etc.

[0003] The body controller mainly includes a housing and a circuit board arranged in the housing. The housing is composed of an upper housing and a lower housing. The upper housing is provided with clearance holes corresponding to the multiple pins on the circuit board. During the assembly process of the body controller, the clearance holes on the upper housing should be aligned with the corresponding pins on the circuit board. However, in the actual production process, the assembly position of the circuit board on the lower housing sometimes has errors, resulting in the clearance holes on the upper housing not being well aligned with the corresponding pins on the circuit board. The force of closing the upper housing during assembly can easily cause damage to the pins. Summary of the invention

[0004] In order to solve the above problems, the present disclosure provides a vehicle body controller housing.

[0005] Specifically, the technical solution of the present disclosure is:

[0006] A vehicle body controller housing comprises an upper housing and a lower housing, wherein the upper housing is provided with a clearance hole corresponding to a pin of a circuit board, and the inner side of the lower housing is provided with a plurality of limiting ribs at intervals along the circumference of the lower housing, wherein the limiting ribs are used to limit the circuit board placed in the lower housing to prevent the circuit board from moving relative to the lower housing.

[0007] In one embodiment, the limiting rib includes a guide portion, a limiting portion and a supporting portion which are arranged in sequence from the upper shell to the lower shell, the guide portion has a guide slope, the guide slope is used to guide the circuit board when the circuit board is installed in the lower shell, the limiting portion is used to limit the circuit board placed in the lower shell, and the supporting portion is used to support the circuit board placed in the lower shell.

[0008] In one embodiment, the lower shell and the upper shell are both square structures, each having four corners, three of the corners of the lower shell are provided with lower bosses, the lower bosses face the upper shell, and one of the corners of the upper shell is provided with an upper boss, the upper boss faces the lower shell, and the upper boss corresponds to the corner of the lower shell without the lower boss.

[0009] Beneficial technical effects of the present disclosure:

[0010] The present invention provides limiting ribs to ensure that the relative position of the circuit board with the lower shell is fixed after the circuit board is installed in the lower shell, so that when the upper shell is covered, the clearance holes on the upper shell can be aligned with the corresponding circuit board pins, effectively preventing the problem that the circuit board pins are crushed by the upper shell due to the clearance holes not being aligned with the circuit board pins.

[0016] The present disclosure is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] In one embodiment, if Figures 1 to 5 As shown, the vehicle body controller housing provided by the present invention includes an upper housing 1 and a lower housing 2. The upper housing 1 is provided with a clearance hole 11 corresponding to the circuit board pin 31. The inner side of the lower housing 2 is provided with a plurality of limiting ribs 21 at intervals along the circumference of the lower housing 2. The limiting ribs 21 are used to limit the circuit board 3 placed in the lower housing 2 to prevent the circuit board 3 from moving relative to the lower housing 2.

[0018] By setting the limiting ribs 21, it can be ensured that the relative position of the circuit board 3 and the lower shell 2 is fixed after being installed in the lower shell 2, so that when the upper shell 1 is covered, the clearance holes 11 on the upper shell 1 can be aligned with the corresponding circuit board pins 31, preventing the problem that the clearance holes 11 are not aligned with the circuit board pins 31 and the circuit board pins 31 are crushed by the upper shell 1.

[0019] See also Figure 3In this embodiment, the limiting rib 21 includes a guide portion 211, a limiting portion 212 and a supporting portion 213 arranged in sequence from the upper shell 1 to the lower shell 2. The guide portion 211 has a guide slope, which is used to guide the circuit board 3 when the circuit board 3 is loaded into the lower shell 2, which helps the circuit board 3 to be loaded smoothly; the limiting portion 212 is used to limit the circuit board 3 placed in the lower shell 2, and the supporting portion 213 is used to support the circuit board 3 placed in the lower shell 2, so that the circuit board 3 is at a certain distance from the bottom of the lower shell 2. In other embodiments, the limiting rib 21 can also be other shapes.

[0020] Considering that the relative orientation error between the upper shell 1 and the lower shell 2 may also cause the clearance hole 11 to be unable to align with the corresponding circuit board pin 31, thereby crushing the circuit board pin 31 when the upper shell 1 is covered, in this embodiment, the lower shell 2 and the upper shell 1 are both square structures, each having four corners, see Figure 4 The lower shell 2 has three corners with lower bosses 22, and the lower bosses 22 face the upper shell 1. Figure 5 An upper boss 12 is provided at one corner of the upper shell 1, and the upper boss 12 faces the lower shell 2. The upper boss 12 corresponds to a corner of the lower shell 2 where the lower boss 21 is not provided. In this way, even if the relative directions of the upper shell 1 and the lower shell 2 are wrong when the upper shell 1 is covered, the upper shell 1 cannot be covered because the upper boss 12 abuts against the lower boss 21, thereby preventing the circuit board pins 31 from being crushed by the upper shell 1.

[0021] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. It should be noted that any modification, equivalent replacement, improvement, etc. made by a person skilled in the art within the spirit and principle of the present disclosure after reading this specification should be included in the protection scope of the present disclosure.
