Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a camera bracket for automotive windshields that can avoid contamination by adhesive oil film. Background Technology

[0002] With the rapid development of automotive intelligence and networking, various electronic components are being integrated into vehicles. Among them, cameras, as an important environmental perception element, are installed in various parts of the vehicle: the front, rear, windshield, rearview mirrors, B-pillars, etc. Cameras collect image information about the vehicle's surroundings and transmit this information to the control system for analysis and processing, which is used for the vehicle's driver assistance functions.

[0003] The camera on the car's windshield is fixed in place by a plastic bracket, which is glued to the windshield with PU adhesive. During the curing process of the PU adhesive and in high-temperature environments under direct sunlight, organic matter will volatilize. The volatilized matter will condense on the windshield to form a foggy oil film. If an oil film forms in the camera's imaging area, it will be unable to capture external image information, thus causing the driver assistance function to fail.

[0004] Therefore, it is evident that the existing technology has the following problems:

[0005] 1. During the curing process of PU adhesive and in high-temperature environments under direct sunlight, organic matter will volatilize. The volatilized matter will condense and form a fogged oil film on the camera imaging area of ​​the windshield, making it impossible to collect external image information, thus causing the driver assistance function to fail.

[0006] 2. The edge of the camera image usually has only one raised rib. There will be a certain gap between the raised rib and the windshield. The volatile substances of PU glue can enter the camera's field of view through the gap and form an atomized oil film. Utility Model Content

[0007] Therefore, this utility model provides a car windshield camera bracket that can avoid oil film contamination of the adhesive layer, in order to overcome the problem in the prior art that PU adhesive will produce volatilized organic matter during the curing process and in the high temperature environment of direct sunlight, and the volatilized matter will condense on the windshield to form a fogging oil film.

[0008] To achieve the above objectives, this utility model provides a car windshield camera bracket that avoids contamination from adhesive oil film. It is a one-piece molded structure, comprising:

[0009] The bracket has a first surface and a second surface;

[0010] The first mounting groove is a U-shaped groove provided on one side of the bracket opening direction;

[0011] The second mounting groove is a wedge-shaped groove located on one side of the bracket in the closing direction and gradually recessed relative to the first surface. The end of the wedge-shaped structure is provided with a through hole adapted to the camera.

[0012] A multi-layer sealing structure is provided at the edge of the second mounting groove to seal the connection between the windshield and the bracket.

[0013] Furthermore, the first surface also includes a third mounting groove symmetrically disposed at the end of the bracket in the opening direction and which is a square recess relative to the first surface.

[0014] Furthermore, the first surface also includes a fourth mounting groove symmetrically disposed in the middle of the bracket near the first mounting groove and being a square recess relative to the first surface.

[0015] Furthermore, the second surface is provided with several boss structures and several reinforcing ribs.

[0016] Furthermore, the first surface also includes a fifth mounting groove symmetrically disposed in the middle of the bracket near the fourth mounting groove and being a square recess relative to the first surface.

[0017] Furthermore, a square through hole adapted to the buckle of the outer shell is provided on the end face of the square recess of the third mounting groove.

[0018] Furthermore, the square recess of the fourth mounting groove has a square through hole on its end face that is adapted to the buckle of the outer shell.

[0019] Furthermore, the plurality of boss structures include a first boss structure, a second boss structure, and a third boss structure disposed on the second surface, as well as a first protrusion and a second protrusion.

[0020] Furthermore, the plurality of reinforcing ribs include a first reinforcing rib disposed on the wedge-shaped protrusion surface of the second surface, a second reinforcing rib disposed on the upper end face of the second boss structure, a third reinforcing rib disposed between the first protrusion and the third mounting groove on the first boss structure of the second surface, and a fourth reinforcing rib disposed on the side of the third reinforcing rib.

[0021] Furthermore, the multi-layer sealing structure can be composed of various materials such as elastomeric materials, foamed materials, and multi-layer raised ribs.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] Furthermore, by setting a multi-layer sealing structure on the first surface of the bracket, a better seal with the windshield can be achieved, which can greatly reduce the diffusion of volatiles, prevent the formation of an oil film in the camera area, protect the camera components, and reduce maintenance costs.

[0024] Furthermore, the bracket housing mounted on the second surface of the bracket can be made more secure by using various snap-fit ​​and groove structures.

[0025] Furthermore, by reducing the formation of oil film in the camera area, the camera components can better perceive the surrounding environment, improving the user's intelligent driving experience and increasing driving safety.

[0026] Furthermore, the multi-layer sealing structure set on the bracket has a wide variety of replaceable materials, which greatly reduces the difficulty of manufacturing. Moreover, the structure is simple and easy to promote. Attached Figure Description
