Description

Technical Field

[0001] The present invention belongs to the technical field of automotive glass, and particularly relates to a bearing device and an automotive windshield. Background Art

[0002] With the increasing popularity of automotive Advanced Driving Assistance System (ADAS), more and more vehicles have started to be equipped with camera modules. An automotive windshield provided with a camera module generally includes a glass substrate, which has a perspective area. The camera module is arranged facing the perspective area of the windshield, and the camera module can observe the driving environment through the perspective area of the windshield. The camera module is usually installed on a base inside the automotive windshield to make the structure of the camera module stable.

[0003] However, due to different vehicle models, the specific installation positions of the camera modules are different, resulting in different installation angles of the camera modules. Most of the existing mounting brackets for camera modules are rigidly fixed, and the angles of the camera modules are fixed. The mounting brackets for camera modules with fixed angles cannot meet the multi-shooting angle requirements of the camera modules, that is, the existing mounting brackets for camera modules have poor applicability and cannot meet the installation angle adjustment of the camera modules. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a bearing device and an automotive windshield, aiming to solve the problems of how to improve the applicability of the bearing device and the stability of adjusting the pitching angle of the camera module.

[0005] To achieve the above purpose, the technical solution adopted in the present application is:

[0006] In a first aspect, a bearing device is provided for bearing a camera module. The bearing device includes a base, a fixing bracket for fixing the camera module and rotatably connected to the base, an elastic member disposed between the fixing bracket and the base and having an elastic deformation force, and a locking member connected to the fixing bracket. The fixing bracket can rotate around a preset axis to adjust the pitching angle of the camera module relative to the base. Two ends of the elastic member are respectively connected to the fixing bracket and the base. The locking member has a locking state and an unlocking state. When the locking member is in the locking state, the locking member restricts the fixing bracket from rotating around the preset axis; when the locking member is in the unlocking state, the locking member releases the restriction on the rotation of the fixing bracket.

[0007] In some embodiments, the fixed bracket is provided with a connection hole, and the locking member movably passes through the connection hole. When the locking member is in the locked state, the locking member abuts against the base to limit the rotation of the fixed bracket around the preset axis; when the locking member is in the unlocked state, the locking member is separated from the base.

[0008] In some embodiments, the elastic member is a spring, and the spring is sleeved outside the locking member.

[0009] In some embodiments, the base includes a bottom wall spaced from the fixed bracket and a limiting boss protruding from a surface of the bottom wall facing the fixed bracket. The spring is sleeved outside the limiting boss. When the locking member is in the locked state, the locking member abuts against the limiting boss.

[0010] In some embodiments, the carrying device further includes a buffer member. The buffer member is disposed between the camera module and the inner wall of the fixed bracket. The buffer member is made of an elastic material and is in a compressed state. The buffer member is used to buffer the vibration generated by the fixed bracket on the camera module.

[0011] In some embodiments, the fixed bracket includes a bottom plate for supporting the camera module and side plates connected to the bottom plate. The side plates are hinged to the base. Two side plates are arranged at intervals, and the two side plates are respectively connected to opposite sides of the bottom plate. The buffer member is disposed between the camera module and the bottom plate.

[0012] In some embodiments, along the direction from the camera module pointing to the bottom plate, the radial dimension of the buffer member gradually increases.

[0013] In some embodiments, the bottom plate is provided with a first avoidance hole for the camera of the camera module to expose, and the base is provided with a second avoidance hole for the camera of the camera module to expose. The second avoidance hole corresponds to the first avoidance hole.

[0014] In some embodiments, the connection hole is configured as a long strip through hole, and the length direction of the connection hole is perpendicular to the preset axis.

[0015] In a second aspect, a vehicle windshield is provided, which includes the above-mentioned carrying device. The vehicle windshield further includes a glass substrate and a camera module, and the carrying device is connected to the glass substrate.

[0016] The bearing device provided by this application can adjust the pitching angle of the camera module relative to the base by setting the base and the fixed bracket rotatably connected to the base. The fixed bracket can rotate around a preset axis to adjust the pitching angle, and the pitching angle of the camera module is fixed by a locking member, thereby realizing flexible multi-angle adjustment of the installation angle of the camera module, adapting to the installation environments of different vehicle models, and improving the applicability of the bearing device. Moreover, the elastic member can provide an elastic supporting force to the fixed bracket. Even when the locking member is in the unlocked state and the fixed bracket rotates freely, the position of the fixed bracket can still be kept stable, making it more convenient for the locking member to lock and unlock the fixed bracket, thus improving the stability of the pitching angle adjustment of the camera module.

[0030] Please refer to Figures 1 to 6, an embodiment of the present application provides a carrier device 100 for carrying a camera module 300. The carrier device 100 includes a base 10, a fixing bracket 20 for fixing the camera module 300 and rotatably connected to the base 10, an elastic member 30 disposed between the fixing bracket 20 and the base 10 and having an elastic deformation force, and a locking member 40 connected to the fixing bracket 20. The fixing bracket 20 can rotate around a preset axis to adjust the pitching angle of the camera module 300 relative to the base 10. The two ends of the elastic member 30 are respectively connected to the fixing bracket 20 and the base 10. The locking member 40 has a locked state and an unlocked state. When the locking member 40 is in the locked state, the locking member 40 restricts the fixing bracket 20 from rotating around the preset axis; when the locking member 40 is in the unlocked state, the locking member 40 releases the restriction on the rotation of the fixing bracket 20.

[0031] In a specific embodiment, the carrier device 100 can be applied to an automotive windshield. The automotive windshield generally includes a glass substrate 200, and a camera module 300 is installed on the glass substrate 200. The camera module 300 can observe the driving environment through the perspective area of the windshield. The carrier device 100 can be used to fix the camera 310 module inside the glass substrate 200 to make the structure of the camera 310 module stable. Specifically, the base 10 of the embodiment of the present application can be used for fixed installation on the glass substrate 200.

[0032] In the embodiment of the present application, when the locking member 40 is in the locked state, the locking member 40 restricts the fixing bracket 20 from rotating around the preset axis, that is, at this time, the fixing bracket 20 cannot rotate freely, and the camera module 300 remains at a preset installation angle; when the locking member 40 is in the unlocked state, the locking member 40 releases the restriction on the rotation of the fixing bracket 20. At this time, the fixing bracket 20 is in a free rotation state, and at this time, the pitching angle of the camera module 300 relative to the base 10 can be adjusted according to actual needs.

[0033] It should be noted that the elastic member 30 is disposed between the fixing bracket 20 and the base 10, and the elastic member 30 has an elastic deformation force. The elastic member 30 separates the fixing bracket 20 and the base 10 and can apply elastic forces in opposite directions to the fixing bracket 20 and the base 10 respectively. When the base 10 is fixed, the elastic member 30 can provide an elastic supporting force for the fixing bracket 20. When the pitching angle of the camera module 300 needs to be adjusted, the fixing bracket 20 can be manually rotated to increase or decrease the angle between the fixing bracket 20 and the base 10. The elastic member 30 can support the fixing bracket 20 well, so that even when the locking member 40 is in the unlocked state and the fixing bracket 20 rotates freely, the position of the fixing bracket 20 can still be kept stable, making the locking and unlocking actions of the locking member 40 more convenient, and further making the adjustment of the pitching angle of the camera module 300 more stable.

[0034] The carrier device 100 provided by the present application is provided with a base 10 and a fixed bracket 20 rotatably connected to the base 10. The fixed bracket 20 can rotate around a preset axis to adjust the pitching angle of the camera module 300 relative to the base 10, and the pitching angle of the camera module 300 is fixed by a locking member 40, so as to realize flexible multi-angle adjustment of the installation angle of the camera module 300, and further adapt to the installation environments of different vehicle models, improving the applicability of the carrier device 100. Moreover, the elastic member 30 can provide an elastic supporting force to the fixed bracket 20. Even when the locking member 40 is in the unlocked state and the fixed bracket 20 rotates freely, the position of the fixed bracket 20 can still be kept stable, making it more convenient for the locking member 40 to lock and unlock the fixed bracket 20, thereby improving the stability of the pitching angle adjustment of the camera module 300.

[0035] In addition, the carrier device 100 of the embodiment of the present application has a simple structure, is easy to process and manufacture, and has a simple operation. It can simplify the installation process, improve the installation efficiency, and improve the convenience of installation.

[0036] In some embodiments, as Figures 1 to 3 shown, the fixed bracket 20 is provided with a connection hole 211, and the locking member 40 movably passes through the connection hole 211. When the locking member 40 is in the locked state, the locking member 40 abuts against the base 10 to limit the rotation of the fixed bracket 20 around the preset axis; when the locking member 40 is in the unlocked state, the locking member 40 is separated from the base 10. Locking and unlocking are achieved by the locking member 40 abutting against the base 10 or separating from the base 10. The operation method is simple, does not consume too much manpower, can save labor costs,

[0037] Optionally, the locking member 40 is an adjusting bolt. By rotating the adjusting bolt clockwise or counterclockwise, the distance between the adjusting bolt and the base 10 can be changed, so that the locking and unlocking actions of the locking member 40 are more relaxed and convenient, and the installation and fixation of the camera module 300 can be made more reliable. Moreover, the manufacturing cost of the adjusting bolt is low and it is easy to replace, thus reducing the maintenance cost.

[0038] In some embodiments, the elastic member 30 is a spring, and the spring is sleeved outside the locking member 40. By sleeving the spring outside the locking member 40, the locking member 40 and the spring share the same axis, realizing coaxial integration, with a compact structure, high space utilization rate, reducing the overall volume, being beneficial to the miniaturization of the carrier device 100, and the coaxial design can ensure uniform compression of the spring, preventing the spring from bending or shifting during compression, avoiding tilting and affecting the supporting effect. In this way, when adjusting the angle, the locking is more reliable and will not loosen due to spring deformation. In the embodiment of the present application, each module of the spring and the adjusting bolt is independently designed, which is convenient for maintenance and replacement.

[0039] In other possible embodiments, the elastic member 30 may also be constructed as an elastic block, and the two ends of the elastic block may respectively press against the fixed bracket 20 and the base 10, which can also make the installation of the fixed bracket 20 and the base 10 more stable. The embodiment of the present application does not make a sole limitation on the specific structure of the elastic member 30.

[0040] In some embodiments, Figure 4 As shown, the base 10 includes a bottom wall 11 spaced apart from the fixing bracket 20 and a limiting boss 13 protruding from the bottom wall 11 facing the fixing bracket 20. The spring is sleeved outside the limiting boss 13. When the locking member 40 is in a locked state, the locking member 40 abuts against the limiting boss 13. By providing the limiting boss 13 and sleeved the spring outside the limiting boss 13, the limiting boss 13 can limit the spring. The outer diameter of the limiting boss 13 forms a gap with the inner diameter of the spring to ensure that the spring always moves along the axis when compressed or extended, preventing lateral deviation or lateral movement. The limiting boss 13 also has a guiding and positioning function. During installation, the operator only needs to sleeve the spring into the limiting boss 13 to automatically center it, which can effectively reduce the assembly time.

[0041] In some embodiments, the base 10 further includes a retaining wall 14 spaced apart from the limiting boss 13. The retaining wall 14 is also convexly disposed on the side of the bottom wall 11 facing the fixed bracket 20. The spring clip is disposed between the limiting boss 13 and the retaining wall 14. The retaining wall 14 can resist the side of the spring away from the limiting boss 13, thereby further improving the limiting effect on the spring. Optionally, one retaining wall 14 can be provided, so as to resist the spring from one direction. Of course, multiple retaining walls 14 can also be provided at intervals, and multiple retaining walls 14 are provided around the circumference of the limiting boss 13, so as to limit the spring from multiple directions, further improving the limiting effect on the spring.

[0042] In some embodiments, the carrying device 100 further includes a buffer 50, which is disposed between the camera module 300 and the inner wall of the fixed bracket 20. The buffer 50 is made of an elastic material and is in a compressed state. The buffer 50 is used to buffer the vibration of the fixed bracket 20 on the camera module 300. The buffer 50 can absorb vibration and impact during the driving of the vehicle, reduce the impact on the camera module 300, thereby improving image stability, and preventing damage to precision components such as the sensor and lens mount of the camera module 300. In addition, the buffer 50 can isolate the fixed bracket 20 from the housing of the camera module 300, and prevent the fixed bracket 20 from directly and rigidly contacting the camera module 300, thereby effectively preventing scratches on the surface of the camera module 300.

[0043] Optionally, the material of the buffer member 50 is silica gel. Silica gel has good elasticity and can effectively absorb and disperse impact force. Moreover, the silica gel buffer member 50 has good electrical insulation performance and is suitable for occasions with high electrical insulation requirements, such as electronic devices. Furthermore, silica gel also has the property of chemical corrosion resistance. It can resist the erosion of most chemical substances and is not easily damaged by substances such as acids, alkalis, and solvents, thereby improving the stability of the buffer member 50. Of course, in other possible embodiments, the material of the buffer member 50 can also be rubber, sponge, etc., and the specific material of the buffer member 50 in the embodiments of the present application is not uniquely limited.

[0044] In the embodiments of the present application, two buffer members 50 are provided, and the two buffer members 50 are arranged at intervals, so as to further improve the absorption effect of vibration and impact. Of course, in other possible embodiments, the number of the buffer members 50 can also be three, four, five or more, and the specific number of the buffer members 50 in the embodiments of the present application is not uniquely limited.

[0045] In some embodiments, the fixed bracket 20 includes a bottom plate 21 for supporting the camera module 300 and side plates 22 connected to the bottom plate 21. The side plates 22 are hinged to the base 10. Two side plates 22 are arranged at intervals and the two side plates 22 are respectively connected to opposite sides of the bottom plate 21. The buffer member 50 is disposed between the camera module 300 and the bottom plate 21. It can be understood that by disposing the buffer member 50 between the camera module 300 and the bottom plate 21, the buffer member 50 can more directly absorb the vibration and impact from the camera module 300. The bottom plate 21 serves as a platform for the camera module 300, and the buffer member 50 can more effectively isolate the vibration here. Moreover, since the bottom plate 21 is in direct contact with the camera module 300, the buffer member 50 can directly absorb the vibration of the camera itself and avoid transmitting the vibration to the base 10 and the windshield, thereby reducing the vibration of the overall structure.

[0046] In addition, the base 10 further includes hinge walls 12 protruding from the bottom wall 11. Two hinge walls 12 are arranged at intervals. The fixed bracket 20 is disposed between the two hinge walls 12, and the two side plates 22 are respectively hinged to the two hinge walls 12, so as to enable the rotation of the fixed bracket 20. It can be understood that the connection holes 211 are formed in the bottom plate 21.

[0047] In some embodiments, along the direction in which the imaging module 300 points towards the bottom plate 21, the radial dimension of the buffer member 50 gradually increases. That is to say, along the direction in which the imaging module 300 points towards the bottom plate 21, the dimension of the buffer member 50 is arranged in a gradually expanding manner. With such a design, the end with a smaller dimension of the buffer member 50 precisely fits the bottom of the imaging module 300, preventing local overpressure from damaging the imaging module 300. The end with a larger dimension of the buffer member 50 is connected to the bottom plate 21, and the impact energy is absorbed through large deformation, which can further improve the buffering effect. The end with a smaller dimension and the end with a larger dimension of the buffer member 50 respectively correspond to the imaging module 300 and the bottom plate 21, which can eliminate the ineffective space of the traditional cylindrical buffer member 50 and improve the space utilization rate. The conical structure is lighter than a cylindrical shape of the same volume, which is beneficial to achieving lightweight. Specifically, the shape of the buffer member 50 is conical.

[0048] In some embodiments, as Figure 5 shown, the bottom plate 21 is provided with a first avoidance hole 212 for the camera 310 of the imaging module 300 to expose, and the base 10 is provided with a second avoidance hole 111 for the camera 310 of the imaging module 300 to expose. The second avoidance hole 111 corresponds to the first avoidance hole 212. By providing the first avoidance hole 212 and the second avoidance hole 111 for the camera 310 of the imaging module 300 to expose, the camera 310 will not be blocked, ensuring the normal operation of the imaging module 300. The other inner walls of the fixing bracket 20 can effectively surround and block the imaging module 300, which can improve the protection effect on the imaging module 300, that is, provide protection for the imaging module 300 in terms of waterproof, dustproof, and sunscreen, effectively improving the service life of the imaging module 300.

[0049] In some embodiments, the connection hole 211 is configured as a long strip-shaped through hole, and the length direction of the connection hole 211 is perpendicular to the preset axis. By configuring the connection hole 211 as a long strip-shaped through hole, the coverage area of the connection hole 211 can be increased. The locking member 40 can slide relative to the connection hole 211 within the range of the long hole. When the connection hole 211 rotates with the fixing bracket 20, the locking member 40 can still correspond to the connection hole 211, allowing the relative positions of the locking member 40 and the connection hole 211 to be adjusted within a certain range, preventing the locking member 40 and the connection hole 211 from not being aligned due to production errors, offset or inclination of the connection hole 211, thereby improving the installation freedom.

[0050] In addition, in the embodiments of the present application, both the fixing bracket 20 and the base 10 are made of high-strength lightweight engineering plastics, so that the fixing bracket 20 and the base 10 have sufficient strength and rigidity. Optionally, the materials of the fixing bracket 20 and the base 10 are polypropylene, which is a plastic material with low density, high molecular weight, high rigidity and high strength. Its weight is only about one-third of that of metal, and it has good corrosion resistance, heat resistance, fatigue resistance and electrical insulation. Polypropylene products are widely used in fields such as automobiles, electrical appliances, medical treatment and food packaging. Of course, in other possible implementation manners, the materials of the fixing bracket 20 and the base 10 can also be polyurethane, polycarbonate, polyamide, polystyrene, etc. The embodiments of the present application do not uniquely limit the specific materials of the fixing bracket 20 and the base 10.

[0051] In some embodiments, the bottom wall 11 is provided with a plurality of mounting holes 112, and the plurality of mounting holes 112 are arranged at intervals. By providing a plurality of mounting holes 112 at different positions, the carrying device 100 can adapt to the mounting requirements of different vehicle models.

[0052] As Figure 6 shown, the present application also proposes an automotive windshield, which includes a carrying device 100, and the specific structure of the carrying device 100 refers to the above embodiments. Further, the automotive windshield further includes a glass substrate 200 and a camera module 300. The carrying device 100 is connected to the glass substrate 200, and the carrying device 100 is used to fix the camera module 300 to make the position of the camera module 300 stable, so as to ensure the stability of data collection.

[0053] To sum up, for the carrying device 100 provided by the present application, by providing the base 10 and the fixing bracket 20 rotatably connected to the base 10, the fixing bracket 20 can rotate around a preset axis to adjust the pitching angle of the camera module 300 relative to the base 10, and the pitching angle of the camera module 300 is fixed by the locking member 40, so as to realize the multi-angle flexible adjustment of the installation angle of the camera module 300, and then adapt to the installation environments of different vehicle models, improving the applicability of the carrying device 100; moreover, the elastic member 30 can provide an elastic supporting force for the fixing bracket 20. Even when the locking member 40 is in the unlocked state and the fixing bracket 20 rotates freely, the position of the fixing bracket 20 can still be kept stable, making it more convenient for the locking member 40 to lock and unlock the fixing bracket 20, thereby improving the stability of the pitching angle adjustment of the camera module 300.

[0054] The above are only optional embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
