Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a camera decorative cover structure and an automobile. Background Art

[0002] At present, automobiles are developing rapidly in the direction of intelligent driving. In-cabin monitoring plays an important role in the safety configuration of intelligent driving. It can monitor the facial expressions, mental states, body movements, and information such as children and items left behind by the main driver, co-driver, and rear passengers, and provide monitoring information for the driver and the driving system. At present, the in-cabin monitoring system is divided into DMS and OMS. DMS monitors the driver, and OMS provides monitoring information for the co-driver and rear passengers. Due to the particularity of the driving environment, infrared light sources are required for fill light in low-light environments to provide the camera with a sufficient brightness environment for shooting and recording in the cabin, and for algorithm recognition. This has high requirements for the camera's stray light processing and image quality.

[0003] Currently, mainstream in-cabin surveillance cameras use decorative cover structural components in conjunction with IR_LED for infrared transmission fill light; however, the light from the infrared light source will be diffusely reflected in the decorative cover structure to the lens to form stray light crosstalk. In addition, the infrared light from the IR_LED will be reflected from the opponent to the camera to form stray light interference, which will reduce image quality, affect algorithm recognition, and reduce safe driving capabilities.

[0004] Therefore, there is an urgent need for a camera decorative cover structure and a car to solve the technical problems existing in the prior art to a certain extent. Utility Model Content

Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0047] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.

[0048] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0049] Although terms such as "first," "second," and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms.

[0065] Specifically, the area ratio of the first infrared cutoff region 5 , the infrared transmission region 11 , and the second infrared cutoff region 6 is 24:5:11.

[0066] Combination Figure 1 As shown, the widths of the first infrared cutoff area 5, the infrared transmission area 11 and the second infrared cutoff area 6 are the same, which is the width of the mounting plate. Therefore, the above-mentioned area ratio is actually the length of the first infrared cutoff area 5, the infrared transmission area 11 and the second infrared cutoff area 6 along the length direction of the mounting plate.

[0067] In this embodiment, a first mounting hole 7 is formed on the second infrared cut-off region 6 , and the first mounting hole 7 is used for mounting a camera.

[0069] Specifically, a connecting hole is provided in the middle of the connecting bracket 8, and in actual use, a bolt can pass through the connecting hole.

[0070] In this embodiment, the infrared cut-off region is formed on the mounting board 2 by using a laser process.

[0071] Specifically, combined Figure 3 As shown, area p is the non-laser process infrared transmission area 11, o1, o2, and o3 are infrared rays directly incident through area p, areas q1 and q2 are laser process areas (i.e., area q1 is the first infrared cut-off area, and q2 is the second infrared cut-off area), and n1, n2, n3, and n4 are the routes of infrared rays diffusely reflected when passing through areas q1 and q2. Figure 3 It can be seen that the reflection path of the light prevents it from being reflected to the lens, thus overcoming the problem of stray light crosstalk.

[0072] Embodiment 2

[0073] Combine the following Figure 4-Figure 6 , a camera decorative cover structure provided in this embodiment is described in detail.

[0074] In this embodiment, a camera decorative cover structure is provided, which can install a camera and an LED lamp; the camera decorative cover structure includes a substrate 1 and a mounting plate 2.

[0075] Specifically, the mounting plate 2 is arranged on one side of the substrate 1, and is combined with Figure 1 As shown, the mounting plate 2 is a groove-shaped structure, one end of which is closed and the other end is open, and a first mounting cavity 3 is formed between the closed end and the side wall.

[0076] Specifically, the substrate 1 is a cylindrical structure, and is surrounded by a second mounting cavity 4 communicating with the first mounting cavity 3 . The camera and the LED lamp are both mounted in the second mounting cavity 4 .

[0077] Specifically, the mounting plate 2 is divided into two infrared cutoff areas and one infrared transmission area 11, and the infrared transmission area 11 is arranged between the two infrared cutoff areas; the infrared cutoff area can cut off infrared light and prevent infrared light from reaching the camera through internal reflection of the substrate 1 and the mounting plate 2 to form stray light crosstalk; the infrared transmission area 11 can provide fill light for the camera through infrared light.

[0078] Specifically, the infrared cut-off area is formed on the mounting board 2 by using a laser process.

[0079] In summary, the present application can cut off the passing infrared light, limit the IR_LED FOV, avoid the reflection of infrared light to the camera to form stray light crosstalk, effectively improve the image quality, improve the algorithm recognition ability, and improve the safe driving ability.

[0080] In this embodiment, the length direction of the mounting plate 2 is parallel to the width direction of the substrate 1 , and the width direction of the mounting plate 2 is parallel to the length direction of the substrate 1 , so that the mounting plate 2 and the substrate 1 form a T-shaped structure.

[0081] Specifically, the two infrared cut-off regions on the mounting plate 2 are respectively a first infrared cut-off region 5 and a second infrared cut-off region 6;

[0082] The first infrared cut-off region 5 , the infrared transmission region 11 , and the second infrared cut-off region 6 are sequentially arranged along the length direction of the mounting plate 2 and extend along the width direction of the mounting plate 2 .

[0083] Specifically, the area ratio of the first infrared cut-off region 5 , the infrared transmission region 11 , and the second infrared cut-off region 6 is 0.31:0.7:0.31.
