Description

Technical Field

[0001] This utility model relates to the field of automotive electronic equipment installation, and in particular to a connection structure for an ADAS forward-looking camera. Background Technology

[0002] With the development of automotive intelligent technology, Advanced Driver Assistance Systems (ADAS) have become standard equipment in modern cars. As one of the core sensors of ADAS systems, the in-vehicle camera is typically installed on the upper inner side of the windshield. To ensure the camera's image quality and optical axis pointing accuracy, existing installation solutions usually include a windshield bracket pre-adheded to the glass surface. The conventional connection method utilizes a positioning structure extending from the camera housing, combined with a limiting groove and elastic clamping element on the windshield bracket, to secure the camera housing to the windshield bracket.

[0003] However, in practical applications, different vehicle platforms or product configurations have varying performance requirements for cameras. This leads to differences in the camera's internal electronic structure (such as circuit board size and number of layers) and optical component specifications. These internal differences directly cause changes in the overall dimensions of the camera housing, which in turn alters the mounting points on the camera housing (such as clip positions and locating pin positions).

[0004] To address the above issues, current solutions require either introducing corresponding windshield brackets for each camera of different sizes or modifying existing windshield bracket molds to match the new mounting points. This necessitates frequent creation of new bracket molds or modification of existing ones, resulting in significant mold costs and consequently high development costs. The design, mold making, and verification processes for new brackets are also time-consuming, making it difficult to meet the time pressures of rapid iteration in automotive projects. Furthermore, these conventional solutions lead to a wide variety of components, increasing the difficulty of material management and warehousing, and hindering product standardization and platform-based promotion. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a connection structure for ADAS forward-looking cameras, so as to realize the universality of windshield brackets. One bracket can be used to adapt to multiple cameras, which significantly reduces the development and material costs of OEMs.

[0006] This utility model proposes a connection structure for an ADAS forward-looking camera, including an extension sleeve fitted onto the locking posts on both sides of the camera housing, and the extension sleeve and the locking posts are detachably connected. The extension sleeve is available in various sizes to match locking posts of different camera housing sizes; the extension sleeve is fixed to the locking post to form a locking assembly, thereby extending the length of the locking post so that the locking assembly can be locked into the snap-fit ​​structure of the windshield bracket at the end furthest from the camera housing, thus enabling the installation of cameras of different sizes without replacing the windshield bracket.

[0007] Preferably, the extension sleeve includes a fixing seat for connecting the locking pin and a locking part that engages with the locking buckle, the locking part being fixedly connected to the fixing seat.

[0008] Preferably, the fixing seat has a groove at the end away from the snap-fit ​​portion, the groove matching the snap-fit ​​post so that the snap-fit ​​post can be inserted into the groove axially.

[0009] Preferably, at least one first threaded hole is provided on the side wall of the fixing seat, the first threaded hole extends radially into the groove, and a second threaded hole corresponding to the first threaded hole is provided on the side wall of the locking post, the first threaded hole and the second threaded hole are connected by a screw.

[0010] Preferably, the snap-fit ​​structure includes a limiting spring and a limiting platform; the limiting spring can switch between an avoidance position and a limiting position; when the limiting spring reaches the limiting position, the limiting spring and the limiting platform cooperate to constrain the snap-fit ​​portion.

[0011] Preferably, the snap-fit ​​portion is curved on the side wall located on one side of the limiting spring, so that the snap-fit ​​portion fits into the limiting spring.

[0012] Preferably, the contact surface between the snap-fit ​​part and the limiting platform is planar, so that the snap-fit ​​part can fit snugly against the limiting platform.

[0013] Preferably, the snap-fit ​​portion has a through hole along the axial direction, the through hole extends to the groove, and the size of the through hole is smaller than the size of the groove, so that the bottom of the groove forms a locking step.

[0014] As described above, the connection structure of the ADAS forward-looking camera involved in this utility model has the following beneficial effects:

[0015] This invention utilizes various extension sleeves to match the locking posts of camera housings of different specifications. The extension sleeves are fixed to the locking posts to form a locking assembly, thereby extending the length of the locking posts. This allows the locking assembly to engage with the snap-fit ​​structure of the windshield bracket at the end furthest from the camera housing, enabling the installation of cameras of different specifications without replacing the windshield bracket. This invention features a simple overall process, low cost, and achieves windshield bracket universality; one bracket can be adapted to multiple cameras, significantly reducing development and material costs for OEMs. Attached Figure Description

[0028] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are only for illustrative purposes and to aid those skilled in the art in understanding and reading the content disclosed herein. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms used in this specification, such as "upper," "lower," "left," "right," and "middle," are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0029] Regarding ADAS forward-facing cameras, it should be noted that, as Figure 1 As shown, the ADAS forward-facing camera includes a camera housing 140 and a camera module 130. The camera module 130 is fixed to the camera housing 140. The camera housing 140 has locking posts 120 on both sides that engage with the windshield bracket. The locking posts 120 are located at the rear of the camera housing 140. Mounting blocks 110 are fixed at both ends of the front of the camera housing 140, and arc-shaped positioning portions are fixed on the mounting blocks 110.

[0030] like Figures 2 to 9 An embodiment of a connection structure for an ADAS forward-looking camera includes an extension sleeve 300 fitted onto two retaining posts on both sides of a camera housing 140. The extension sleeve 300 is connected to the retaining posts 120, and the connection method includes, but is not limited to, a threaded connection, as long as the extension sleeve 300 can be removed from the retaining posts 120. The extension sleeve 300 is available in various sizes to match retaining posts 120 of different camera housing sizes. The extension sleeve 300 is fixed to the retaining post 120 to form a snap-fit ​​assembly, thereby extending the length of the retaining post 120. This allows the snap-fit ​​assembly to snap into the snap-fit ​​structure 400 of the windshield bracket 500 at the end furthest from the camera housing, thus enabling the installation of cameras of different sizes without replacing the windshield bracket 500.

[0031] In use, the specifications of the extension sleeve 300 are determined according to the specifications of the front-view camera to be installed. This can be understood as follows: the spacing between the locking posts on both sides of the camera housing differs for different camera housing specifications. The specifications of the extension sleeve 300 are determined based on the different camera housing specifications, allowing it to be installed on the corresponding locking posts, extending the length of the locking post 120 to the snap-fit ​​structure 400 of the windshield bracket. Since the windshield bracket is pre-fixed to the windshield, the mounting block 110 located on the rear side of the camera housing 140 is inserted into the fixing structure 510 on the front side of the windshield bracket (e.g., ...). Figure 3 (As shown). Rotate the camera housing 140. Under the action of the arc-shaped positioning part, rotate the camera housing 140 towards the windshield bracket 500, so that the extension sleeve 300 can be snapped into the snap-fit ​​structure 400 of the windshield bracket at the end away from the camera housing 140 (as shown). Figure 4 (As shown), and then the installation is completed. This embodiment avoids replacing the windshield bracket according to different camera housing specifications, realizing the universality of the windshield bracket. One bracket can be adapted to multiple cameras, significantly reducing the development and material costs for OEMs.

[0032] In one embodiment, such as Figure 8 and Figure 9 As shown, the extension sleeve 300 includes a fixing seat 310 for connecting the locking post 120 and a locking part 320 that cooperates with the snap-fit ​​structure 400. The locking part 320 is fixedly connected to the fixing seat 310. In this embodiment, in a preferred manner, the locking part 320 and the fixing seat 310 are integrally formed, and the fixing seat 310 and the locking post 120 can be detachably connected by snap-fit, threaded connection, screw connection, etc.

[0033] In one embodiment, such as Figures 7 to 9 As shown, the fixing base 310 has a groove 311 at the end away from the locking part 320. The groove 311 matches the locking post 120, that is, the outer shape of the groove 311 is the same as that of the locking post 120, so that the locking post 120 can be inserted into the groove 311 axially. The locking post 120 and the groove 311 are fitted with a clearance fit, and the locking post 120 and the fixing base 310 are fixedly connected by a connector, which makes disassembly and assembly convenient.

[0034] In one embodiment, such as Figure 8 As shown, at least one first threaded hole 312 is provided on the side wall of the fixing base 310. The first threaded hole extends radially into the groove. A second threaded hole corresponding to the first threaded hole 312 is provided on the side wall of the retaining post. The first threaded hole 312 and the second threaded hole are connected by screws. In a preferred embodiment, multiple first threaded holes 312 are provided along the side wall of the fixing base 310, and each first threaded hole is arranged circumferentially to improve the stability of the fixing base 310 during installation. The first threaded hole 312 and its corresponding second threaded hole can be determined according to the actual working conditions.

[0035] In one embodiment, such as Figure 7 and Figure 9 As shown, the snap-fit ​​portion 320 has a through hole 321 along the axial direction, which extends to the groove 311. The size of the through hole 321 is smaller than the size of the groove 311, forming a locking step at the bottom of the groove 311. When the snap-fit ​​post 120 is installed in place, the end of the snap-fit ​​post 120 abuts against the locking step, effectively preventing the snap-fit ​​post from being over-inserted. In this embodiment, the through hole 321, while ensuring the structural strength of the snap-fit ​​portion 320, achieves material savings and overall component weight reduction, thus reducing manufacturing costs.

[0036] In one embodiment, such as Figure 5 As shown, the latching structure 400 includes a limiting spring 410 and a limiting platform 420. The limiting spring 410 can switch between an avoidance position and a limiting position. When the limiting spring 410 reaches the limiting position, the limiting spring 410 and the limiting platform 420 cooperate to constrain the latching part 320.

[0037] Furthermore, the snap-fit ​​portion 320 has a curved sidewall on the side of the limiting spring piece, so that the snap-fit ​​portion 320 and the limiting spring piece 410 fit tightly together, effectively increasing the contact area and making the snap-fit ​​portion 320 fit tightly together with the limiting spring piece 410.

[0038] During installation, the mounting block 110 located on the rear side of the camera housing 140 is inserted into the fixing structure on the front side of the windshield bracket. The camera housing 140 is rotated towards the windshield bracket 500. The locking part 320 applies a pushing force to the end of the limiting spring 410, causing the end of the limiting spring 410 to overcome its own elasticity and move from the limiting position to the clearance position, so that the locking part 320 can enter the limiting platform 420. When the locking part 320 smoothly enters the limiting platform 420, the pushing force applied to the end of the limiting spring is greatly reduced, and at the same time, the compressed limiting spring 410 releases its elasticity, causing the end of the limiting spring 410 to return from the clearance position to the limiting position, thus constraining the locking part 320 between the limiting platform 420 and the limiting spring 410. The limiting spring 410 has a limiting structure at its end. The inner side of the limiting structure is arc-shaped and fits against the side wall of the locking part 320 to ensure stable locking.

[0039] Furthermore, the contact surfaces of the locking part 320 and the limiting platform 420 are arranged in a planar manner, which effectively increases the contact area and allows the locking part 320 to fit snugly against the limiting platform 420, greatly limiting the micro-movements and shaking that may occur when the locking part is subjected to force, and maintaining the locking stability.

[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
