[0031] In order to make the person skilled in the art better understand the scheme of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0032] The first, second and the like ordinal numbers used in the present text are used to distinguish different parts with the same name, and do not represent a specific order or primary and secondary relationship. Several in the present text can be one, or two or more.

[0033] For the convenience of understanding and description, the vehicle front-view camera module and the mounting device thereof are described below, and the beneficial effects are not repeated.

[0034] In the embodiment, the vehicle front-view camera module includes a plurality of cameras and a mounting device, each camera is mounted on the mounting device, and then mounted on the front side of the vehicle through the mounting device, for example, can be mounted on the front windshield. The number and type of cameras are related to the needs of the Advanced Driving Assistance System (ADAS) of the vehicle, and can be flexibly set according to needs, which is not limited here.

[0035] Please refer to Figure 1 and Figure 2 , Figure 1 is an exploded view of the mounting device of the vehicle front-view camera module provided in an embodiment of the present application, Figure 2 is Figure 1 partial structure exploded view of the mounting device.

[0036] In the embodiment, the mounting device of the vehicle front-view camera module includes a bracket 10, the bracket 10 includes a plurality of mounting cavities 11, and the mounting cavities 11 are used to mount the cameras; each mounting cavity 11 is provided with a cover body 20, the cover body 20 seals the open end of the mounting cavity 11, and the cover body 20 is detachably connected with the bracket 10.

[0037] The above mounting device can be used by first mounting the camera in the corresponding mounting cavity 11 of the bracket 10, and then mounting the cover body 20 at the open end of the corresponding mounting cavity 11. In this way, after all the cameras of the vehicle front-view camera module are installed, the bracket 10 is installed on the vehicle. When it is necessary to replace or maintain the camera, the corresponding cover body 20 can be detached, and then the camera to be replaced or maintained is detached, and the replaced or maintained camera is installed in the mounting cavity 11, and the cover body 20 is reinstalled. The operation is convenient. By decoupling the camera from the bracket 10, when the camera is replaced or maintained, the entire bracket 10 does not need to be detached from the vehicle, and the state of other cameras is not affected, and other cameras do not need to be recalibrated. The workload of maintaining the vehicle front-view camera module can be reduced, and the maintenance cost can be reduced.

[0038] The mounting device can be used in multiple application scenarios, for example, it can be used in a vehicle ADAS test car to realize stable acquisition and analysis of camera image signals in the early development stage of the ADAS domain controller. The mounting device can also be used in other application scenarios, not limited to test cars.

[0039] In Figure 1 and Figure 2In the shown example, the bracket 10 is provided with three installation cavities 11, which are arranged in a straight line. Correspondingly, the vehicle-mounted front-view camera module includes three cameras, which are respectively installed in the three installation cavities 11, and the mounting device is provided with three cover bodies 20, which are respectively matched with the three installation cavities 11.

[0040] For example, the three cameras can be used to implement TSR (Traffic Sign Recognition, traffic sign recognition), LKA (Lane Keep Assist, lane keeping assistance) and AEB (Autonomous Emergency Braking-Vehicle, automatic emergency braking) functions.

[0041] In other embodiments, when the bracket 10 is provided with a plurality of installation cavities 11, the arrangement mode of the plurality of installation cavities 11 can be determined according to the needs of the driving assistance system, and is not limited to the above-mentioned straight-line arrangement mode.

[0042] In a specific implementation, the bracket 10 can be installed on the front windshield of the vehicle and located in the interior space of the vehicle. The bracket 10 includes opposite first and second sides 10A and 10B, the first side 10A faces the front windshield, and the second side 10B faces away from the front windshield. The surface shape of the bracket 10 at the first side 10A can match the outer shape of the front windshield to fit the front windshield. For example, the surface of the bracket 10 at the first side 10A can be connected with the front windshield by means of adhesion or the like.

[0043] The open end of the installation cavity 11 is located at the second side 10B of the bracket 10, that is, the cover body 20 is arranged at the second side 10B of the bracket 10, so as to facilitate dismounting the cover body 20 and thus dismounting the corresponding camera.

[0044] Please refer to Figure 3 and Figure 4 , Figure 3 for Figure 1 the structure diagram of the bracket; Figure 4 for Figure 1 the structure diagram of the maintenance cover plate.

[0045] In some embodiments, the bracket 10 has a maintenance opening 12, and the mounting device includes a maintenance cover plate 30 for sealing the maintenance opening 12, and the maintenance cover plate 30 is detachably connected with the bracket 10.

[0046] The area between the first side 10A of the bracket 10 and the front windshield after the bracket 10 is installed behind the front windshield of the vehicle can have dust accumulation or water vapor, which affects the imaging quality of the camera. After the installation device sets the access opening 12 and the matching access cover plate 30, in application, the access cover plate 30 can be removed as needed to clean the area between the first side A of the bracket 10 and the front windshield through the access opening 12, without the need to disassemble the entire bracket 10 for cleaning, and the maintenance workload of recalibrating the camera caused by disassembling the bracket 10 is also avoided.

[0047] In specific implementations, the access cover plate 30 is installed on the bracket 10 from the second side 10B of the bracket 10 to block the access opening 12. In this way, the access cover plate 30 can be conveniently removed from the inside of the vehicle to clean and maintain the area between the bracket 10 and the front windshield.

[0048] The bracket 10 is provided with a first mounting portion 14 at the second side 10B, and the access cover plate 30 is provided with a second mounting portion 31. The second mounting portion 31 of the access cover plate 30 can be connected to the first mounting portion 14 through a screw or other fastener.

[0049] The first mounting portion 14 can be provided with multiple first mounting portions 14, and the multiple second mounting portions 14 can be arranged at intervals around the periphery of the access opening 12. The number and position of the second mounting portion 31 of the access cover plate 30 match the first mounting portion 14.

[0050] For example, the first mounting portion 14 can be a columnar structure with a threaded hole, and the second mounting portion 31 can be a plate-shaped structure with a mounting hole. The screw can be threadedly connected to the threaded hole of the first mounting portion 14 through the mounting hole of the second mounting portion 31. The connection is reliable and convenient to disassemble and assemble.

[0051] In the illustrated example, the access opening 12 is in the shape of a quadrilateral, and the first mounting portion 14 is provided with four first mounting portions 14, respectively located at the four corner positions of the access opening 12. The shape of the access cover plate 30 matches the access opening 12, and the four second mounting portions 31 are respectively arranged at the four corner positions of the access cover plate 30.

[0052] In other embodiments, the access opening 12 can have other forms, such as an oval or a circle, and the access cover plate 30 can be matched.

[0053] Please refer to Figure 5 , Figure 5 for a structural schematic diagram of the installation device in specific embodiments. Figure 5 The oblique section line in FIG. 1 indicates the area where the bracket 10 is provided with a reflective layer at the first side 10A.

[0054] In some embodiments, the bracket 10 has a recess 13 formed from the first side 10A to the second side 10B of the bracket 10. It can be understood that the recess 13 is recessed away from the front windshield. The recess 13 includes a bottom wall portion 131 and a side wall portion provided on the periphery of the bottom wall portion 131, and the aforementioned access hole 12 is specifically provided on the bottom wall portion 131. The side wall portion has a number of through holes 1324 corresponding to the number of the mounting cavities 11, and the through holes 1324 are in communication with the mounting cavities 11. In this way, after the camera is mounted in the mounting cavities 11, the lens of the camera is positioned corresponding to the through holes 1324, and the lens of the camera is directed to the front of the vehicle through the through holes 1324 to facilitate image shooting.

[0055] It can be understood that the through holes 1324 are provided on the first side 10A of the bracket 10, and the open ends of the mounting cavities 11 are located on the second side 10B of the bracket 10.

[0056] Specifically, the side wall portion includes a first side wall portion 1321, a second side wall portion 1322 and a third side wall portion 1323, and the second side wall portion 1322 and the third side wall portion 1323 are located on both sides of the first side wall portion 1321. After the bracket 10 is mounted on the front windshield, the first side wall portion 1321 extends substantially along the width direction of the vehicle. The through holes 1324 in communication with the mounting cavities 11 are provided on the first side wall portion 1321 to ensure that the lens of the camera is directed to the front of the vehicle after the camera is mounted. It can be understood that the cavity wall portion forming the mounting cavities 11 includes part of the first side wall portion 1321.

[0057] In some embodiments, the surface of the access cover plate 30 facing the first side 10A is provided with a first light reflection layer 40, i.e. the surface of the access cover plate 30 facing the front windshield is provided with the first light reflection layer 40. In this way, the light entering the recess 13 through the front windshield can form irregular diffuse reflection on the surface of the first light reflection layer 40, weakening the light and avoiding the light directly reflecting to the camera through the surface of the access cover plate 30 to form glare and reduce the imaging quality of the camera.

[0058] In some embodiments, at least one of the surface of the second side wall portion 1322, the surface of the third side wall portion 1323 and the surface of the bottom wall portion 131 facing the first side 10A is provided with a second light reflection layer 50. In this way, the light can also be avoided from directly reflecting to the camera through the surface of the second side wall portion 1322, or the surface of the third side wall portion 1323, or the surface of the bottom wall portion 131 to form glare and reduce the imaging quality of the camera.

[0059] In specific implementation, the second reflective layer 50 can be arranged on the surface of the second side wall 1322 only, or on the surface of the third side wall 1323 only, or on the surface of the bottom wall 131 only; or the second reflective layer 50 can be arranged on the surface of the second side wall 1322 and the surface of the third side wall 1323, or on the surface of the second side wall 1322 and the surface of the bottom wall 131, or on the surface of the second side wall 1322, the surface of the third side wall 1323 and the surface of the bottom wall 131, and so on; or the second reflective layer 50 can be arranged on the surface of the second side wall 1322, the surface of the third side wall 1323 and the surface of the bottom wall 131 as shown in FIGS. 13B and 13C. Figure 1 and Figure 5 the surface of the second side wall 1322, the surface of the third side wall 1323 and the surface of the bottom wall 131.

[0060] The first reflective layer 40 and the second reflective layer 50 can be made of the same reflective material or different reflective materials. For example, the first reflective layer 40 and the second reflective layer 50 can be made of reflective velvet. For example, the reflective velvet can be fixed to the corresponding surface of the bracket 10 by pasting.

[0061] For a better understanding, Figure 6 it can be understood that, in the case where no reflective layer is arranged, as shown in FIG. 13A, the light entering the recess 13 through the front windshield is directly reflected to the camera through the surface of the recess 13, which is easy to form glare; while after the reflective layer is arranged, as shown in FIGS. 13B and 13C, the light entering the recess 13 through the front windshield is diffusely reflected through the first reflective layer 40 or the second reflective layer 50, which can avoid the formation of glare, thereby improving the imaging quality of the camera. Figure 6 Figure 6 (b) shows, the light entering the recess 13 through the front windshield is diffusely reflected through the first reflective layer 40 or the second reflective layer 50, which can avoid the formation of glare, thereby improving the imaging quality of the camera.

[0062] In specific implementation, the second side wall 1322 of the recess 13 is arranged to be inclined away from the third side wall 1323 at the wall segment away from the first side wall 1321, and the third side wall 1323 is arranged to be inclined away from the second side wall 1322 at the wall segment away from the first side wall 1321. In this way, the second side wall 1322 and the third side wall 1323 of the recess 13 away from the first side wall 1321 are substantially V-shaped at one end, so as to meet the shooting requirements of the camera.

[0063] Specifically, the opening shape and size of the recess 13 away from the first side wall 1321 are related to the field of view angle of the camera.

[0064] For a better understanding, Figures 7 to 9 , Figure 7 FIG. 14 is a structure schematic view of another perspective of the mounting device in the specific embodiment, Figure 8 FIG. 15 is an A-A cross-sectional view of FIG. 14, Figure 7 FIG. 16 is a local enlarged view of B part of FIG. 15. Figure 9 Figure 8 FIG. 16 is a local enlarged view of B part of FIG. 15.

[0065] ​​In the embodiment, the cover 20 and the bracket 10 can be detachably connected by fasteners such as screws. In combination with Figure 2 , the cover 20 can be provided with lugs 21 having through holes, and the bracket 10 is provided with threaded holes at positions corresponding to the through holes of the lugs 21 at the open end of the mounting cavity 11. The fasteners such as screws can be threadedly connected through the through holes of the lugs 21 and the threaded holes of the bracket 10.

[0066] Figure 2 In the example shown, the cover 20 is generally square in structure, and two opposite side walls of the cover 20 are provided with lugs 21. Correspondingly, the mounting cavity 11 can be provided with threaded holes matched with the two lugs 21. In this way, the stability and reliability of the connection between the cover 20 and the bracket 10 can be ensured. In other embodiments, the structure of the cover 20 and the number and layout of the lugs 21 can be adjusted adaptively as needed.

[0067] In a specific implementation, the cover 20 has a first end wall 22 facing the bracket 10, and the bracket 10 has a second end wall 15 facing the cover 20. After the cover 20 is connected to the bracket 10, the first end wall 22 of the cover 20 corresponds in position to the second end wall 15. In actual installation, a reserved gap d is provided between the first end wall 22 and the second end wall 15, as shown in Figure 9 . In this way, when the cover 20 and the bracket 10 are connected by fasteners, the aforementioned reserved gap d can be eliminated by the locking force of the fasteners, so that the inner end wall 23 of the cover 20 is pressed against the camera mounted in the mounting cavity 11, forming a setting similar to an interference fit. By using the cover 20 to press and fix the camera, the stability of the position of the camera on the bracket 10 can be ensured, and the camera can be prevented from shaking during vehicle driving or in other situations, so that the imaging quality of the camera can be improved.

[0068] Exemplarily, the reserved gap d can be 0.5 mm.

[0069] The embodiments of the present application also provide a vehicle, which comprises a front windshield and a vehicle-mounted forward-looking camera module mounted on the front windshield. The vehicle-mounted forward-looking camera module is the vehicle-mounted forward-looking camera module described in the foregoing embodiments, and has similar technical effects to the vehicle-mounted forward-looking camera module.

[0070] Exemplarily, the vehicle can be a test vehicle used for early-stage research and development of an ADAS domain controller.

[0071] The principles and implementation modes of the present application are described by using specific examples in the present application. The above description of the embodiments is only used to help understand the method of the present application and its core idea. It should be noted that, for those skilled in the art, without departing from the principles of the present application, some improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
