Description

Technical Field

[0001] This utility model relates to a DMS mounting structure for a low-pressure injection molded A-pillar trim panel. Background Technology

[0002] With EU regulations requiring vehicles to be equipped with Driver Monitoring Systems (DMS), and given the crucial role DMS plays in enhancing vehicle safety, intelligence, and driving experience, modern cars often incorporate this system. The A-pillar trim panel is one of the available locations for DMS devices, especially for already developed models where it's often the optimal placement. A-pillar trim panel manufacturing processes typically include textured injection molding and low-pressure injection molding. For low-pressure injection molded A-pillar trim panels, limitations in manufacturing processes, styling, and DMS camera placement prevent one-piece molding. Therefore, disassembly is required to assemble the DMS camera to meet the angle requirements for facial recognition, improve the efficiency of facial recognition algorithms, increase assembly efficiency, and reduce production costs. Based on this, this application addresses the DMS camera assembly problem when existing low-pressure injection molded A-pillar trim panels cannot be integrally molded. Utility Model Content

[0003] This utility model provides a DMS mounting structure for a low-pressure injection molded A-pillar trim panel to solve the problems existing in the prior art.

[0004] The technical solutions adopted in this utility model are as follows:

[0005] A DMS mounting structure for a low-pressure injection molded A-pillar trim panel, including

[0006] The A-pillar trim panel body has mounting holes.

[0007] A camera assembly, wherein the camera assembly is disposed in the mounting hole and is fixed to the A-pillar upper trim panel body;

[0008] The DMS cover plate is fixed to the outside of the A-pillar trim panel to seal the mounting holes. The DMS cover plate has holes for the probe of the camera assembly to be exposed.

[0009] Furthermore, the mounting hole is surrounded by several insertion holes, and the DMS cover plate is provided with welding ribs that are adapted to the insertion holes.

[0010] Furthermore, the inner wall of the DMS cover plate is provided with several raised reinforcing ribs.

[0011] Furthermore, several BOSS pillars are distributed on the inner end face of the A-pillar trim panel and around the mounting holes.

[0012] Furthermore, the camera assembly includes a camera bracket and a camera, with the camera fixed to the camera bracket and the camera bracket fixed to the corresponding BOSS column.

[0013] This utility model has the following beneficial effects:

[0014] By designing a DMS camera and A-pillar trim panel installation structure that fully guarantees the freedom of shape, the defect rate of A-pillar trim panels using low-pressure injection molding process is greatly reduced. This not only meets the angle requirements of face recognition and improves the efficiency of face recognition algorithm operation, but also improves the assembly efficiency of DMS camera device and reduces production costs.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] The DMS camera and A-pillar trim panel installation structure designed in this utility model have been fully verified in actual matching and installation processes, fully meeting the design requirements and ensuring the realization of functional components. The following is a further detailed description of this utility model in conjunction with the accompanying drawings.

[0021] like Figures 1 to 5 A DMS mounting structure for a low-pressure injection molded A-pillar trim panel includes an A-pillar trim panel body 1, a DMS cover plate 2, and a camera assembly.

[0022] The A-pillar trim panel body 1 has mounting holes 11, and several BOSS pillars 12 are distributed on the inner end face of the A-pillar trim panel body around the mounting holes 11. The DMS cover plate 2 is fixed at the mounting holes 11 and is located on the outside of the A-pillar trim panel body. The DMS cover plate 2 is used to close the mounting holes 11.

[0023] The camera assembly is located inside the DMS cover plate 2 and is fixed to the A-pillar trim panel body 1. The DMS cover plate has a hole for the camera 4 in the camera assembly to be exposed.

[0024] The camera assembly includes a camera bracket 3 and a camera 4. The camera 4 is fixed to the camera bracket 3, and the camera bracket 3 is fixed to the corresponding BOSS column 12.

[0025] A number of insertion holes 13 are provided around the mounting hole 11, and welding ribs 21 that are adapted to the insertion holes 13 are provided on the DMS cover plate 2.

[0026] The camera bracket 3 is fixed to the BOSS pillar 12 of the A-pillar trim assembly by two self-tapping screws. Several raised reinforcing ribs 22 are provided on the inner wall of the DMS cover plate 2. The reinforcing ribs 22 can increase the strength of the DMS cover plate 2. During the assembly of the DMS cover plate 2, the internal reinforcing ribs 22 also play a role in limiting the position of the camera 4, that is, the camera 4 abuts against the reinforcing ribs 22, controlling the gap of the camera 4 assembly.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
