Description

Technical Field

[0001] This utility model relates to the field of windshield technology, and in particular to a windshield, a camera mounting structure thereon, and an automobile. Background Technology

[0002] Dashcams, consisting of a camera and other components, have become an essential part of automobiles, recording information from the driver's field of vision while driving. Currently, most newly released car models integrate the camera into the vehicle during the manufacturing process; the specific installation method is as follows... Figure 1 As shown, the shooting device 1 is fixed inside the vehicle by the mounting frame 2, with its lens facing the windshield 3, to collect the field of view information in front of the vehicle. As a device for recording the field of view in front of the vehicle during driving, the shooting device 1 requires a large field of view to ensure the completeness of the information collected. Therefore, it is necessary to ensure that there are no obstructions between the shooting device 1 and the windshield 3 to maintain a certain clearance space 4, so that the shooting device 1 has a large field of view when shooting. Specifically... Figure 1 The installation method in the middle requires that the mounting frame 2 be placed below the shooting device 1 and leave a certain distance from the windshield 3 to ensure that the shooting device 1 has a large shooting field of view.

[0003] However, this installation method also has some problems. To ensure a sufficiently large field of view for the shooting device 1, the mounting frame 2 is spaced a certain distance from the windshield 3, leaving no obstruction between them. This causes light from inside the vehicle to reflect off the windshield 3 and enter the field of view of the shooting device 1, resulting in light pollution and affecting the video quality. Furthermore, since the mounting frame 2 does not separate the shooting device 1 from the vehicle interior, pollutants from inside the vehicle can adhere to the shooting device 1 over time, also affecting the video quality.

[0004] In view of this, the purpose of this utility model is to provide a windshield and a camera mounting structure thereon, as well as an automobile, to solve the above-mentioned problems.

[0005] This utility model provides a windshield, including a windshield body, the windshield body having opposing outer and inner surfaces, a lens on the outer surface of the windshield body, one surface of the lens being fitted to and shaped with the outer surface of the windshield body; the lens is a convex lens.

[0006] Optionally, the lens has an elliptical cross-sectional shape, with the major axis of the lens's cross-section extending in the same direction as the length of the windshield body, and the minor axis of the lens's cross-section extending in the same direction as the width of the windshield body.

[0007] Optionally, the convex surface of the lens is divided into a first curved surface and a second curved surface connected in sequence along the extension direction of the minor axis of its cross-section, the first curved surface being located above the second curved surface, and the average curvature of the first curved surface being greater than the average curvature of the second curved surface.

[0008] Optionally, the lens and the windshield body are integrally formed.

[0009] Optionally, the lens is bonded to the windshield body.

[0010] Optionally, it also includes an optically transparent adhesive, through which the lens is bonded to the windshield body.

[0014] This utility model also provides a car, including the windshield as described above or the camera mounting structure as described above.

[0015] The beneficial effects of this utility model are as follows: by setting a lens on the windshield body to increase the field of view of the camera, the camera has a larger field of view when shooting, so there is no need to reserve a large space between the camera and the windshield body to meet the field of view of the camera. The frame for mounting the camera can be configured to completely isolate the camera from the windshield body, preventing light inside the car from being reflected by the windshield body into the camera's field of view and causing light pollution.

[0022] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

They are used only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.

[0026] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0027] like Figure 2 As shown, this embodiment provides a windshield, including a windshield body 10. The windshield body 10 has opposing outer and inner surfaces. The outer surface is the surface of the windshield body 10 facing the vehicle, and the inner surface is the surface of the windshield body 10 facing the interior of the vehicle. A lens 20 is provided on the outer surface of the windshield body 10. One surface of the lens 20 is fitted to and shaped with the outer surface of the windshield body 10. The lens 20 is a convex lens. The position of the lens 20 on the windshield body 10 corresponds to the camera 30 inside the vehicle. External light rays are refracted by the lens 20 and enter the lens of the camera 30. Since the lens 20 is a convex lens, it can refract and concentrate the light rays in front of the vehicle into a smaller area, so that a large space does not need to be reserved between the front of the camera 30 and the windshield body 10 to meet the shooting field of view of the camera 30.

[0028] In this embodiment, the windshield uses a lens 20 to refract and concentrate the light from the front of the vehicle into a smaller area. The camera 30 receives the light refracted by the lens 20, allowing the camera 30 to acquire the light from the front of the vehicle without requiring a large space between it and the windshield body 10. Specifically, as shown... Figure 2 As shown, Figure 2 The angle between the two inherent field-of-view boundary lines is the initial field-of-view angle of the camera 30 lens. After the light is refracted by the lens 20, the angle between the two corrected field-of-view boundary lines is significantly larger than the angle between the two inherent field-of-view boundary lines, thereby improving the shooting angle of the camera 30. The mounting frame for the camera 30 can connect to the inner surface of the windshield body 10, isolating the camera 30 from the vehicle interior space and preventing light from the vehicle interior from entering the lens of the camera 30 after being refracted by the windshield body 10, thus affecting the shooting quality. It also prevents dust from the vehicle interior from falling into the lens of the camera 30 and causing lens contamination.

[0029] Furthermore, Figure 2The lens 20 shown has a longitudinal section and an elliptical cross-section. The major axis of the lens 20's cross-section extends in the same direction as the length of the windshield body 10, while the minor axis extends in the same direction as the width of the windshield body 10. The cross-sectional shape of the lens 20 is not limited to an ellipse; it can also be rectangular, etc., characterized by a length greater than its width. The camera 30 at the front of the vehicle collects information about the forward view during vehicle operation, primarily focusing on the road surface and recording interactions between the vehicle and pedestrians or other vehicles, such as pedestrians, oncoming traffic, or vehicles ahead. It does not collect much information about the sky above the vehicle. Therefore, the cross-sectional shape of the lens 20 is an ellipse or a near-elliptical irregular shape with a length greater than its width. This minimizes the size of the lens 20 and avoids aesthetic issues caused by an excessively large lens 20 resulting in a large uneven surface on the windshield body 10.

[0030] Specifically, the length of lens 20 is 85mm-95mm, the width of lens 20 is 55mm-65mm, and the height of lens 20 is 4mm-6mm. In this embodiment, the length (corresponding to the major axis) of lens 20 is 90mm, the width (corresponding to the minor axis) of lens 20 is 60mm, and the height of lens 20 is 5mm.

[0031] Furthermore, such as Figure 2As shown, the convex surface of lens 20 is divided into a first curved surface 21 and a second curved surface 22 connected sequentially along the extension direction of the minor axis. The first curved surface 21 is located above the second curved surface 22, and the average curvature of the first curved surface 21 is greater than the average curvature of the second curved surface 22. Specifically, on lens 20, this means that the average height of the portion corresponding to the first curved surface 21 is less than the average height of the portion corresponding to the second curved surface 22; in other words, the thickness of the portion corresponding to the second curved surface 22 on lens 20 is greater than the thickness of the portion corresponding to the first curved surface 21. The purpose of this configuration is that the information collected by the camera 30 during vehicle movement is more focused on the ground, while the thickness of the part corresponding to the second curved surface 22 of the lens 20 is made larger, so that more light from the ground can be refracted through the lens 20 into the field of view of the camera 30. The part corresponding to the first curved surface 21 on the lens 20 is more inclined to refract light from the field of view above the vehicle. The camera 30 does not need to collect too much information from above the vehicle. Therefore, the convex surface of the lens 20 is configured such that the average curvature of the first curved surface 21 is greater than the average curvature of the second curved surface 22. This is also to minimize the volume of the lens 20 and avoid the aesthetic problem of large-scale unevenness on the outer surface of the windshield body 10 due to the excessive volume of the lens 20. Furthermore, the average curvature of the second curved surface 22 is less than the average curvature of the first curved surface 21, making the convex surface of the lens 20 an inclined surface. The lens 20 is located on the windshield body 10, ensuring that at least the first curved surface 21 of the lens 20 is smoothly transitioned to the windshield body 10, so that the convex surface of the lens 20 matches the shape of the windshield body 10, reducing the aesthetic impact of the lens 20 on the outer surface of the windshield body 10.

[0032] In some embodiments, the lens 20 and the windshield body 10 are integrally formed.

[0033] In some embodiments, the lens 20 is bonded to the windshield body 10 using optically transparent adhesive. The optically transparent adhesive is transparent, does not affect the aesthetics of the windshield body 10, and provides a strong bond. Furthermore, bonding the lens 20 to the windshield body 10 with optically transparent adhesive allows the lens 20 to be manufactured separately, adapting to windshields from multiple manufacturers without requiring modifications to the windshield design; the lens 20 can simply be bonded to mass-produced windshields.

[0034] In some embodiments, the windshield body 10 has a black coating area 11, and the lens 20 is located below the black coating area 11. Since the lens 20 increases the shooting angle of the camera 30, the black coating area 11 on the windshield body 10 does not need to avoid the shooting angle of the camera 30, which facilitates the design of the shape of the black coating area 11 on the windshield body 10 and makes the vehicle more aesthetically pleasing.

[0035] In summary, the windshield provided in this embodiment, by adding a lens 20 to the windshield body 10, allows the in-vehicle camera 30 to collect forward field of view information. External field of view light is refracted into the lens of the camera 30 through the lens 20. This eliminates the need to reserve a large field of view space for the camera 30, making it easier for the mounting frame of the camera 30 to connect with the inner surface of the windshield body 10. This isolates the camera 30 from the interior space, preventing light from the interior from being reflected into the camera 30 and causing light pollution. It also prevents dust from the interior from falling into the camera 30 and causing lens contamination.

[0036] like Figure 2 As shown, this embodiment also provides a camera mounting structure, including a camera 30, a mounting base 40, and a windshield as described above. The camera 30 is mounted inside the vehicle via the mounting base 40, and the lens of the camera 30 faces the lens 20 on the windshield body 10. The mounting base 40 has a decorative cover plate 41, which is located below the camera 30 and is connected to the inner surface of the windshield body 10 to isolate the camera 30 from the vehicle interior space.

[0037] In summary, the camera mounting structure provided in this embodiment can increase the shooting angle of the camera 30 through the lens 20, thereby eliminating the need to reserve space below the mounting base 40 for the camera 30 to meet the shooting field of view. The camera 30 is isolated from the vehicle interior space by connecting the decorative cover 41 to the inner surface of the windshield body 10 (either by abutment or adhesion), preventing light from the vehicle interior from being reflected by the windshield body 10 into the lens of the camera 30 and affecting the shooting effect, or preventing dust from the vehicle interior from entering the camera 30 and causing lens contamination.

[0038] This embodiment also provides a vehicle, including the windshield as described above.

[0039] This embodiment also provides a car, including the camera mounting structure described above.

Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
