[0029] Please refer to Figure 1 This embodiment provides a lens support structure 100, including a frame and a support plate 110. The two ends of the support plate 110 are rotatably connected to the frame. At least two sets of bonding bosses 120 are provided on the surface of the support plate 110. Each set of bonding bosses 120 includes multiple bonding bosses 121 of the same shape. The bonding bosses 121 of any two sets of bonding bosses 120 have different shapes. The bonding bosses 121 are used to align and bond with the bonding surface 221 on the lens 210. The curvature of the curved surface formed by connecting the top surfaces of the multiple bonding bosses 121 of each set of bonding bosses 121 is equal to the curvature of the corresponding bonding area of ​​the lens 210.

[0030] Specifically, the lens support structure 100 includes a frame and a support plate 110. The frame has two support rods. Correspondingly, two rotating shafts 111 are respectively provided at opposite ends of the support plate 110. The plate surface of the support plate 110 is rotatably connected to the frame through the two rotating shafts 111. When the lens 210 is placed on the plate surface of the support plate 110, the image position can be adjusted by rotating the support plate 110.

[0031] The support plate 110 has at least two sets of bonding bosses 120 on its surface. Each set of bonding bosses 120 includes multiple bonding bosses 121 of the same shape, and the shapes of the bonding bosses 121 in any two sets of bonding bosses 120 are different. By setting the number of sets of bonding bosses 120, a corresponding number of lenses 210 can be matched, and each different type of lens 210 corresponds to one set of bonding bosses 120.

[0032] For example, in one specific embodiment of this application, such as Figure 1As shown, the support plate 110 has two sets of bonding bosses 120 on its surface. One set of bonding bosses 121 consists of cylindrical bonding bosses 121 of the same shape and size, while the other set consists of hexagonal bonding bosses 121 of the same shape and size. Therefore, the support plate 110 can be matched with two types of lenses 210.

[0033] In this application, there is no limitation on the specific number of bonding boss groups 120. There can be two, three, four or more bonding boss groups 120. At the same time, there is no limitation on the number of bonding bosses 121 included in each bonding boss group 120, as long as it is ensured that the lens 210 is evenly stressed when it is bonded to multiple bonding bosses 121 during installation.

[0034] The side of the lens 210 facing the support plate 110 has an adhesive surface 221. The adhesive surfaces 221 of different types of lenses 210 correspond to the adhesive bosses 121 of different adhesive boss groups 120. For example, in one specific embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, since it has two sets of adhesive bosses 120, the support plate 110 can be matched with two types of lenses 210. When one type of lens 210 is connected to the support plate 110, the adhesive surface 221 on the lens 210 is circular, and the position of the adhesive surface 221 corresponds to the position of multiple cylindrical adhesive bosses 121, so that the adhesive surface 221 can be bonded to the circular adhesive bosses 121. Similarly, when the other type of lens 210 is connected to the support plate 110, the adhesive surface 221 on the lens 210 is hexagonal, and the position of the adhesive surface 221 corresponds to the position of multiple hexagonal adhesive bosses 121, so that the adhesive surface 221 can be bonded to the hexagonal adhesive bosses 121.

[0035] The differences in windshield surface shape and installation position of different car models necessitate the use of various different surface shapes of lens 210. Since the curvature of different surface shapes of lens 210 is usually different, it is difficult to adapt them to the same lens 210 bracket. Therefore, a special support structure must be developed for each type of lens 210, resulting in a large number of parts and high mold costs.

[0036] To address the aforementioned issues, a single lens support structure 100 can simultaneously accommodate lenses 210 with different surface shapes. In this lens support structure 100, the curvature of the curved surface formed by the top surfaces of multiple bonding bosses 121 connected in each group of bonding bosses 121 is equal to the curvature of the bonding area of ​​the corresponding lens 210. This arrangement ensures that when each type of lens 210 is connected to its corresponding bonding boss 121 via the bonding surface 221, a stable connection is achieved through matching curvatures. Furthermore, this arrangement ensures uniform adhesive wall thickness between different lenses 210 and the support plate 110, thereby guaranteeing dimensional stability and consistent image quality for the lens 210 assembly under high and low temperature conditions.

[0037] It should be noted that, in one possible embodiment of this application, firstly, the bonding boss 121 is a polygonal prism or a cylinder. The polygonal prism can be a triangular prism, a square prism, etc., and this application does not impose any restrictions on its specific structure. This arrangement ensures that the top surface of the bonding boss 121 is flat, providing a larger contact area when its top surface contacts the bonding surface 221 of the lens 210, thereby enhancing the bonding strength.

[0038] Second, a damping structure (not shown in the figure) is provided at the rotational connection between the support plate 110 and the frame. The damping structure can apply a certain resistance force to the rotation process, making the rotation process of the support plate 110 more stable, allowing the support plate 110 to rotate at a relatively slow and controllable speed, thereby achieving precise adjustment of the HUD imaging position.

[0039] The lens support structure 100 provided in this application includes a frame and a support plate 110. The opposite ends of the support plate 110 are rotatably connected to the frame. When the lens 210 is placed on the support plate 110, the support plate 110 can synchronously drive the lens 210 to rotate relative to the frame, thereby adjusting the image position. To improve the adaptability and flexibility of the lens support structure 100, at least two sets of adhesive bosses 120 are provided on the surface of the support plate 110. Each set of adhesive bosses 120 includes multiple adhesive bosses 121 of the same shape. The number of sets of adhesive bosses 120 is related to the number of lens supports. The lens holder structure 100 is adapted to a corresponding number of lens types 210; the bonding bosses 121 of any two sets of bonding bosses 120 have different shapes to adapt to different types of lenses 210 respectively; the bonding bosses 121 are used to bond with the bonding surface 221 on the lens 210, so that the lens 210 is fixedly connected to the support plate 110; the curvature of the curved surface formed by the top surfaces of multiple bonding bosses 121 in each set of bonding bosses 121 is equal to the curvature of the corresponding bonding area of ​​the lens 210, so that the support plate 110 can simultaneously meet the assembly connection of multiple lenses 210. The above-mentioned lens holder structure 100 can adapt to multiple lenses 210, improving adaptability and flexibility of use, and reducing production costs.

[0040] In one possible implementation of this application, such as Figure 1 As shown, the multiple bonding bosses 121 of each bonding boss group 120 are evenly distributed on the surface of the support plate 110. This even distribution ensures that the support plate 110 experiences more uniform force when connected to the lens 210, and also guarantees uniform adhesive wall thickness when bonding the bonding bosses 121 to the lens 210. This ensures that the lens 210 assembly maintains dimensional stability and stable imaging quality under high and low temperature environments.

[0041] For example, such as Figure 1 As shown, the support plate 110 is also provided with at least one positioning structure 130 for engaging with the mating structure 230 on the lens 210 for positioning; when the positioning structure 130 engages with the mating structure 230 on the lens 210, the adhesive boss 121 aligns with and is bonded to the adhesive surface 221 on the lens 210.

[0042] Specifically, to ensure that the adhesive surface 221 on the lens 210 and the adhesive protrusion 121 on the support plate 110 can be aligned and bonded when the lens 210 is installed with the support plate 110, such as... Figure 1As shown, a positioning structure 130 is also provided on the support plate 110, and correspondingly, a mating structure 230 adapted to the positioning structure 130 is provided on the lens 210. Preferably, there are multiple positioning structures 130, which are evenly distributed on the support plate 110; the number of mating structures 230 is equal to the number of positioning structures 130 and their positions correspond, and the multiple mating structures 230 are engaged with the multiple positioning structures 130 one-to-one, so as to further improve the connection stability between the lens 210 and the support plate 110.

[0043] In one specific embodiment of this application, the positioning structure 130 is a limiting hole and the mating structure 230 is a limiting post; in another specific embodiment of this application, the positioning structure 130 is a limiting post and the mating structure 230 is a limiting hole, and the lens support structure 100 can achieve the alignment and installation of the lens 210 and the support plate 110 through the snap-fit ​​of the limiting hole and the limiting post.

[0044] In another aspect of this application embodiment, a HUD lens assembly is also provided, including a lens 210 and a lens support structure 100; the back of the lens 210 is provided with an adhesive area group 220, the adhesive area group 220 includes a plurality of adhesive surfaces 221 of the same shape, and the adhesive surfaces 221 of the adhesive area group 220 are correspondingly provided with adhesive protrusions 121 of any adhesive protrusion group 120 of the lens support structure 100.

[0045] Specifically, the HUD lens assembly includes a lens 210 and a lens support structure 100. Different bonding area groups 220 are provided on the back of the lenses 210 with different surface shapes, so as to be adapted to different bonding boss groups 120 provided on the surface of the support plate 110.

[0046] like Figure 2 and Figure 3 As shown, each bonding area group 220 includes multiple bonding surfaces 221 with the same shape. When the lens 210 is bonded to the support plate 110, the shape and position of the bonding surface 221 can correspond to the bonding boss 121 of the matching bonding boss group 120.

[0047] This arrangement significantly enhances the robustness of the connection between the lens 210 and the lens holder structure 100. By bonding multiple matching adhesive surfaces 221 to corresponding adhesive protrusions 121, the lens 210 is more stably fixed on the holder. Even when encountering bumps, vibrations, or other complex road conditions during vehicle operation, the lens 210 remains in the correct position, ensuring that the clarity and accuracy of the HUD image are unaffected. Furthermore, it further demonstrates the versatility and flexibility of the entire HUD lens assembly. Since the lens holder structure 100 has multiple sets of adhesive protrusions 120 of different shapes, the corresponding lens 210 only needs to have an adhesive area 220 of a corresponding shape on its back according to its own design characteristics to adapt to different types of lens holder structures 100.

[0048] It should be noted that, in addition to the above-described embodiment of providing an adhesive boss assembly 120 on the support plate 110 and an adhesive area assembly 220 on the bonding surface 221 of the lens 210, it is also possible to provide an adhesive area assembly 220 on the support plate 110 and an adhesive boss assembly 120 on the bonding surface 221 of the lens 210. As long as the adhesive boss assembly 120 and the adhesive area assembly 220 can be well adapted to ensure stable bonding, this application does not impose any restrictions on the specific arrangement.

[0049] For example, such as Figure 2 and Figure 3 As shown, the lens 210 has at least one mating structure 230 on the side facing the lens support structure 100, which is used to engage and position with the positioning structure 130 on the support plate 110 of the lens support structure 100, so that the bonding boss 121 is aligned with the bonding surface 221 and bonded.

[0050] Specifically, the lens 210 is provided with a mating structure 230 that can be adapted to the positioning structure 130 on the support plate 110. The number of mating structures 230 is equal to the number of positioning structures 130 and their positions correspond. Multiple mating structures 230 are engaged with multiple positioning structures 130 one by one to further improve the connection stability between the lens 210 and the support plate 110.

[0051] In one specific embodiment of this application, the mating structure 230 is a limiting post and the positioning structure 130 is a limiting hole; in another embodiment of this application, the mating structure 230 is a limiting hole and the positioning structure 130 is a limiting post. The HUD lens assembly can achieve the alignment and installation of the lens 210 and the support plate 110 through the snap-fit ​​of the limiting hole and the limiting post.

[0052] For example, to ensure that the limiting post can be stably engaged in the limiting hole, the length of the limiting post is greater than the thickness of the adhesive boss 121. This is to avoid the situation where the limiting post cannot be engaged in the limiting hole when the adhesive boss 121 is bonded to the adhesive surface 221 due to the limiting post being too short. The length direction of the limiting post and the thickness direction of the adhesive boss 121 are both in the same direction as the thickness direction a of the support plate 110.

[0053] The above description is merely an optional embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0054] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
