Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a glass bracket for mounting ADAS in automobiles. Background Technology

[0002] With the widespread application of autonomous driving technology, the installation of Advanced Driver Assistance Systems (ADAS) in automobiles has become an industry standard.

[0003] ADAS (Advanced Driver Assistance Systems) are typically installed on the upper-middle part of the inside of a car's windshield to obtain a good field of vision. However, the windshields of different car models vary greatly in terms of curvature, tilt angle, and curvature, which means that ADAS mounting brackets often need to be customized and developed for specific car models, making it impossible to achieve cross-model compatibility.

[0004] In the current technology, the common practice in the industry is to develop a plastic bracket that matches the curvature of the glass for each model and fix it to the inside of the glass by adhesive. This method not only increases the cost and cycle of component development, but also brings risks in mold development, quality verification and supply chain management. In addition, ADAS usually requires fine-tuning of the angle after installation to meet the vision requirements, but traditional fixed brackets often lack convenient and reliable angle adjustment mechanisms. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a glass bracket for installing ADAS in automobiles, which can effectively solve the shortcomings of the prior art.

[0006] A glass bracket for mounting ADAS in automobiles, comprising:

[0007] A bracket structure that is attached to the inside-of-vehicle side of the car's windshield;

[0008] An ADAS structure connected to the side of the bracket structure away from the vehicle's windshield;

[0009] A locking assembly for connecting one end of the ADAS structure is provided on the bracket structure. The locking assembly includes ball-head locking structures connected to both sides of one end of the ADAS structure and corresponding fasteners provided on the bracket structure for connecting the ball-head locking structures.

[0010] A rotating assembly is provided on the bracket structure for connecting the end of the ADAS structure away from the foot assembly. The rotating assembly includes an extension portion connected to both sides of the end of the ADAS structure away from the foot assembly, a mounting shaft connected to the side of the extension portion away from the ADAS structure, a bushing structure sleeved on the mounting shaft, a mounting seat for abutting against the bushing structure, and a spring piece structure with one end connected to the mounting seat for abutting against the mounting shaft. The bushing structure includes a bushing body sleeved on the mounting shaft, an anti-rotation portion connected to the side of the bushing body facing the extension portion and with both ends abutting against the ADAS structure, and an abutting portion connected to the side of the bushing body facing the mounting seat for abutting against the mounting seat.

[0011] Compared with existing technologies, the advantages of this invention are as follows: Through the modular design of the bracket structure, ADAS structure, clamping pin assembly, and rotating assembly, the same bracket structure can be adapted to the ADAS installation requirements of different vehicle models. Cross-platform compatibility can be achieved with only minor adjustments to local structures, significantly reducing the types of parts and the number of molds required. The bushing body, anti-rotation part, abutment part, mounting base, and spring structure in the rotating assembly work together to achieve precise rotational adjustment of the ADAS structure around the mounting axis. The anti-rotation part contacts the ADAS structure to prevent self-rotation, and the abutment part cooperates with the mounting base to provide a stable support surface. By replacing bushing structures of different thicknesses, stepless or graded adjustment of the ADAS structure's pitch angle can be achieved, ensuring the accuracy of vision calibration and improving the overall system performance. The ball joint clamping pin structure and the snap fastener provide a connection method that combines flexibility and rigidity, absorbing vibrations during vehicle operation and preventing the ADAS structure from falling off under extreme conditions, thus improving the system's reliability in complex environments. All connection structures are designed with plug-in, snap-fit, or screw connections, allowing for the installation and angle adjustment of the ADAS structure without complex tools, reducing assembly difficulty and training costs on the production line.

[0012] Furthermore, the mounting base includes a mounting base body, a slot disposed on the side of the mounting base body facing the mounting shaft for abutting against the abutting part, and a spring holder disposed on the mounting base body for connecting one end of the spring structure.

[0013] Furthermore, a limiting member is provided on the top of the spring holder for abutting against the end of the spring structure facing the mounting shaft.

[0014] Furthermore, a groove for connecting the mirror structure is provided on the side of the bracket structure facing the windshield of the car, and the camera of the ADAS structure is positioned facing into the groove.

[0015] Furthermore, a sealant applicator groove for applying glass glue is provided on the side of the bracket structure facing the windshield of the car, and the bracket structure is attached to the side of the windshield facing the interior of the car by glass glue.

[0016] Furthermore, a bracket limiting block for abutting against the windshield is provided on the side of the bracket structure facing the windshield of the vehicle, and the bracket limiting block is located on the side of the bracket structure away from the groove.

[0017] Furthermore, the bracket structure is also provided with mounting slots for installing solar and rain sensors.

[0018] Furthermore, a plastic spring structure for abutting against the ADAS structure is provided on the side of the bracket structure away from the windshield of the car. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Please see Figures 1 to 6 The glass bracket for installing ADAS in automobiles according to embodiments of the present invention includes:

[0032] A bracket structure 10 is attached to the side of the car's windshield facing the inside of the vehicle.

[0033] ADAS structure 20 is connected to the side of the bracket structure 10 away from the windshield of the vehicle.

[0034] A locking pin assembly 30 is provided on the bracket structure 10 for connecting one end of the ADAS structure 20. The locking pin assembly 30 includes ball-head locking pin structures 31 connected to both sides of one end of the ADAS structure 20, and a buckle 32 provided on the bracket structure 10 corresponding to the ball-head locking pin structures 31 for connecting the ball-head locking pin structures 31.

[0035] A rotating assembly 40 is disposed on the bracket structure 10 for connecting the end of the ADAS structure 20 away from the foot clamp assembly 30. The rotating assembly 40 includes an extension portion 41 connected to both sides of the end of the ADAS structure 20 away from the foot clamp assembly 30, a mounting shaft 42 connected to the side of the extension portion 41 away from the ADAS structure 20, a bushing structure 43 sleeved on the mounting shaft 42, a mounting seat 44 for abutting against the bushing structure 43, and a spring piece structure 45 connected at one end to the mounting seat 44 for abutting against the mounting shaft 42. The bushing structure 43 includes a bushing body 431 sleeved on the mounting shaft 42, an anti-rotation portion 432 connected to the side of the bushing body 431 facing the extension portion 41 and with both ends abutting against the ADAS structure 20, and an abutting portion 433 connected to the side of the bushing body 431 facing the mounting seat 44 for abutting against the mounting seat 44.

[0036] Understandably, through the modular design of the bracket structure 10, the ADAS structure 20, the clamping pin assembly 30, and the rotating assembly 40, the same bracket structure 10 can be adapted to the ADAS installation requirements of different vehicle models. Cross-platform compatibility can be achieved with only minor adjustments to the local structure, significantly reducing the types of parts and the number of molds required. The bushing body 431, the anti-rotation part 432, the abutment part 433, the mounting base 44, and the spring sheet structure 45 in the rotating assembly 40 work together to achieve precise rotational adjustment of the ADAS structure 20 around the mounting shaft 42. The anti-rotation part 432 contacts the ADAS structure 20 to prevent rotation, and the abutment part 433... The bushing 33, in conjunction with the mounting base 44, provides a stable support surface. By replacing the bushing structure 43 with different thicknesses, the pitch angle of the ADAS structure 20 can be adjusted steplessly or in stages, ensuring the accuracy of the field of vision calibration and improving the overall system performance. The ball joint clamp structure 31 and the fastener 32 provide a connection method that combines flexibility and rigidity, which can absorb vibrations during vehicle operation and prevent the ADAS structure 20 from falling off under extreme conditions, thus improving the reliability of the system in complex environments. All connection structures are designed with plug-in, snap-fit, or screw connections, allowing the installation and angle adjustment of the ADAS structure 20 to be completed without complicated tools, reducing the assembly difficulty and training costs on the production line.

[0037] Furthermore, the mounting base 44 includes a mounting base body 441, a slot 442 disposed on the mounting base body 441 facing the mounting shaft 42 for abutting against the abutting part 433, and a spring plate seat 443 disposed on the mounting base body 441 for connecting one end of the spring plate structure 45.

[0038] Understandably, the slot 442 provides a clear installation position for the abutment part 433 of the bushing structure 43, ensuring that the bushing structure 43 will not shift during installation, thereby ensuring the adjustment accuracy of the ADAS structure 20 angle; the setting of the spring plate seat 443 allows the spring plate structure 45 to be directly installed on the mounting base 44, forming an integrated force-bearing system, which enhances the rigidity and fatigue resistance of the overall structure and avoids the risk of loosening or breakage caused by the separate installation of the spring plate structure 45.

[0039] Furthermore, a limiting member 444 is provided on the top of the spring holder 443 for abutting against the end of the spring structure 45 facing the mounting shaft 42.

[0040] Understandably, the limiting member 444 can effectively constrain the maximum stroke of the spring structure 45 and prevent it from breaking.

[0041] Furthermore, a groove 11 for connecting the mirror structure 12 is provided on the side of the bracket structure 10 facing the windshield of the car, and the camera of the ADAS structure 20 is positioned facing into the groove 11.

[0042] Understandably, by precisely designing the depth and tilt angle of the groove 11, the angle between the camera optical axis of the ADAS structure 20 and the windshield can be in the optimal range, reducing image distortion caused by glass refraction and improving the recognition accuracy of the ADAS structure 20; at the same time, the optical arrangement requirements are integrated into the design of the bracket structure 10, avoiding the need to add a light shield or adjust the bracket, saving space and cost.

[0043] Furthermore, a glue-applying groove 13 for applying glass glue is provided on the side of the bracket structure 10 facing the windshield of the car, and the bracket structure 10 is attached to the side of the windshield facing the interior of the car by glass glue.

[0044] Understandably, the glue applicator 13 can guide the glue to spread evenly on the bonding surface, avoiding insufficient glue or overflow, and ensuring bonding strength and aesthetics.

[0045] Furthermore, a bracket limiting block 14 for abutting against the windshield is provided on the side of the bracket structure 10 facing the windshield of the vehicle, and the bracket limiting block 14 is provided on the side of the bracket structure 10 away from the groove 11.

[0046] It should be noted that, specifically in this embodiment, the stent limiting block 14 is a limiting block that can be partially removed.

[0047] Understandably, by setting a partially removable limiting block on the side of the bracket structure 10 facing the windshield of the car, the same bracket structure 10 body can adapt to windshields with different curvatures. During installation, the bracket limiting block 14 only needs to be trimmed according to the actual curved surface of the glass to make the bracket structure 10 fit well with the glass. Therefore, it is not necessary to develop a special bracket for each curved surface of the glass. Only a few standard brackets and adjustable limiting block solutions need to be stocked, which greatly simplifies material management and after-sales maintenance spare parts system.

[0048] Furthermore, the bracket structure 10 is also provided with a mounting slot 15 for mounting a solar and rain sensor.

[0049] Understandably, integrating the ADAS structure 20 and the sunlight and rain sensor, two devices typically located on the upper part of the windshield, onto the same bracket structure 10 maximizes the use of the limited space at the top of the glass, leaving room for the placement of other devices (such as the rearview mirror and DMS camera).

[0050] Furthermore, a plastic spring structure 16 for abutting against the ADAS structure 20 is provided on the side of the bracket structure 10 away from the windshield of the vehicle.

[0051] Understandably, the plastic spring structure 16 provides upward elastic support at the bottom of the ADAS structure 20, forming a front-to-back elastic fixing system with the spring structure 45 at the rear end, making the ADAS structure 20 more evenly stressed and reducing stress concentration or structural deformation caused by single-point hard connection; the plastic spring structure 16 allows a certain amount of deformation, which can compensate for the manufacturing tolerance of the ADAS structure 20 housing or the minor deviations in the installation process of the bracket structure 10, ensuring that the ADAS structure 20 can always be installed in place stably and without stress.

[0052] In summary, the glass bracket for installing ADAS in automobiles according to the above embodiments of the present invention, through the modular design of the bracket structure, ADAS structure, clamping components, and rotating components, allows the same bracket structure to be adapted to the ADAS installation requirements of different vehicle models. Cross-platform compatibility can be achieved with only minor adjustments to local structures, significantly reducing the types of parts and the number of molds required. The bushing body, anti-rotation part, abutment part, mounting base, and spring structure in the rotating component work together to achieve precise rotational adjustment of the ADAS structure around the mounting axis. The anti-rotation part contacts the ADAS structure to prevent self-rotation, and the abutment part cooperates with the mounting base. Providing a stable support surface, the ADAS structure's pitch angle can be infinitely or steppedly adjusted by changing bushing structures of different thicknesses, ensuring the accuracy of vision calibration and improving the overall system performance. The ball joint clamp structure and the fastener provide a connection method that combines flexibility and rigidity, which can absorb vibrations during vehicle operation and prevent the ADAS structure from falling off under extreme conditions, improving the system's reliability in complex environments. All connection structures are designed with plug-in, snap-fit, or screw connections, allowing the installation and angle adjustment of the ADAS structure to be completed without complicated tools, reducing the assembly difficulty and training costs on the production line.
