Technical Field
[0001] This utility model relates to the field of automotive technology, and in particular to a reflector assembly and a head-up display device. Background Technology
[0002] Currently, head-up displays (HUDs) are widely used in automobiles. While the vehicle is in motion, the HUD allows the driver to obtain driving information without taking their eyes off the road, ensuring driving safety. A typical HUD consists of a housing, an image generation unit, and a reflector housed within the housing. The image generation unit generates an image containing driving information (such as vehicle speed and navigation information), and the reflector reflects the image out of the HUD and onto the vehicle's windshield, from where it is reflected into the driver's eyes. Existing reflectors are typically rotatably connected to the housing via bearing components, allowing the reflector to rotate relative to the housing to adjust the reflection angle and ensure the image is reflected to a set height.
[0003] However, existing bearing components are typically complex in structure and large in size, leading to assembly difficulties. Furthermore, due to the limited installation space within the head-up display device, bearing components need to be custom-made, resulting in higher device costs. Utility Model Content

[0028] Currently, existing bearing components are typically complex in structure and large in size, leading to assembly difficulties. Furthermore, due to the limited installation space within head-up display devices, bearing components need to be custom-made, resulting in high device costs.
[0029] To solve the above-mentioned technical problems, this utility model provides a reflector assembly and a head-up display device, which are small in size, easy to assemble, and have a simple structure, thus saving costs.
[0030] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below.
[0031] refer to Figures 1 to 5 This utility model provides a reflector assembly, including a bracket 1, a top cap 3, and a locking mechanism 4. Another embodiment of this utility model provides a head-up display device, including the aforementioned reflector assembly, a housing 6, and an image generation unit (not shown). A mounting base 2 is disposed inside the housing 6, and the mounting base 2 includes a groove 21. The locking mechanism 4 is detachably connected to the mounting base 2. The image generation unit is located within the housing 6 and is used to generate an image, which is reflected by the reflector assembly. This application does not limit the structural relationship between the groove 21 and the mounting base 2; the mounting base 2 may include the groove 21, meaning the mounting base 2 may be integrally formed with the groove 21. The mounting base 2 and the groove 21 may also be two independent components. Specifically, when the groove 21 and the mounting base 2 are two independent components, the mounting base 2 has a receiving space, and the groove 21 may be located within this receiving space.
[0032] For details, please refer to Figures 1 to 3 The bracket 1 is equipped with a reflector 5, and one end of the bracket 1 is equipped with a first rotating shaft 11. The end of the first rotating shaft 11 is equipped with a sphere 111. The sphere 111 is rotatably disposed in the groove 21. The side wall of the groove 21 near the first rotating shaft 11 is provided with a clearance opening 211, and the first rotating shaft 11 passes through the clearance opening 211.
[0033] Exemplarily, the inner surface of the groove 21 is spherical, and the shape of the groove 21 is adapted to the shape of the sphere 111, that is, the outer surface of the sphere 111 can fit against the inner surface of the groove 21. The top cap 3 is disposed on the side of the sphere 111 facing away from the groove 21, and the bottom surface of the top cap 3 contacts the sphere 111 to prevent the sphere 111 from falling out of the groove 21. This application does not limit the shape of the bottom surface of the top cap 3. In some embodiments, the bottom surface of the top cap 3 is flat, which facilitates processing by the operator. In other embodiments, the bottom surface of the top cap 3 can also be an inwardly concave spherical surface, and the shape of this spherical surface is adapted to the shape of the sphere 111, thereby enhancing the assembly stability of the top cap 3 and the sphere 111.
[0034] refer to Figures 2 to 4 The locking mechanism 4 is disposed outside the top cap 3 and is used to fix the position of the top cap 3 relative to the groove 21. The locking mechanism 4 includes a positioning member 41, which includes a pressing part 411 and a connecting part 412. Exemplarily, the pressing part 411 and the connecting part 412 are generally L-shaped, and ribs are provided between the two sides of the pressing part 411 and the two sides of the connecting part 412. The pressing part 411 is connected to one end of the connecting part 412, the pressing part 411 protrudes from the side wall of the connecting part 412 and directly or indirectly abuts against the top cap 3, and the other end of the connecting part 412 is detachably connected to the mounting base 2. This application does not limit the specific connection method between the connecting part 412 and the mounting base 2, which can be any method such as bolt connection, pin connection, snap connection, etc.
[0035] The reflector assembly provided in this application can replace the existing complex bearing assembly simply by setting a groove 21 and a top cap 3. When it is necessary to rotate the reflector 5, it is only necessary to rotate the ball 111 within the groove 21. The top cap 3 can prevent the ball 111 from falling out of the groove 21, making the structure safe and reliable. Compared with the prior art, this application can reduce the size of the components, facilitate assembly, and has a simple structure, thus saving costs.
[0036] Further, refer to Figure 3 and Figure 4 The locking mechanism 4 also includes an elastic element 42, which is disposed between the top cap 3 and the pressing part 411. One end of the elastic element 42 abuts against the top cap 3, and the other end of the elastic element 42 abuts against the pressing part 411. The top cap 3 has a hole 31, and a limiting post 32 is provided inside the hole 31. Figure 5As shown. The end of the elastic member 42 facing the top cap 3 is inserted into the hole 31 and sleeved on the limiting post 32. Exemplarily, the elastic member 42 is a compression spring. The limiting post 32 and the top cap 3 are an integral structure, and this application does not limit the cross-sectional shape of the limiting post 32. In some embodiments, the cross-sectional shape of the limiting post 32 is cross-shaped to facilitate the processing of the limiting post 32. In other embodiments, the cross-sectional shape of the limiting post 32 can also be triangular, quadrilateral, or hexagonal, etc. By providing the elastic member 42 between the top cap 3 and the pressing part 411, this application can avoid the problem of the top cap 3 and the ball 111 getting stuck, causing the ball 111 to be unable to rotate.
[0037] Optionally, refer to Figure 4 The connecting part 412 has a hook 4121 at one end away from the pressing part 411. The mounting base 2 has a limiting groove (not shown in the figure) that matches the shape of the hook 4121. The hook 4121 engages with the limiting groove. When the hook 4121 engages with the limiting groove, the elastic member 42 undergoes compression deformation to press the top cap 3 against the ball 111, so as to prevent the ball 111 from falling out of the groove 21.
[0038] Optionally, refer to Figure 1 The bracket 1 has a second rotating shaft 12 at the end opposite to the first rotating shaft 11. The second rotating shaft 12 and the first rotating shaft 11 are coaxially arranged. The reflector assembly also includes a driving component (not shown in the figure). The driving end of the driving component is connected to the second rotating shaft 12 and is used to drive the second rotating shaft 12 to rotate around its own axis. By setting the second rotating shaft 12 and the driving component, when it is necessary to rotate the reflector 5 and adjust the reflection angle, the driving component drives the second rotating shaft 12 to rotate, thereby driving the reflector 5 to rotate. At this time, the first rotating shaft 11 also rotates synchronously, and the sphere 111 on the first rotating shaft 11 rotates in the groove 21.
[0039] Optionally, refer to Figure 1 The reflector 5 has an inwardly concave arc-shaped reflective surface 51. By setting the reflective surface 51 to be arc-shaped, this application enables the reflective surface 51 to match the curvature of the vehicle's windshield, thereby effectively solving the problem of image distortion caused by the curvature of the windshield. By precisely matching the curvature of the reflective surface 51 with that of the windshield, it can be ensured that images containing driving information (such as vehicle speed, navigation information, etc.) can be accurately and clearly projected onto the windshield, improving the driving experience.
[0040] Optionally, the reflector assembly further includes a base, which includes a groove 21. An embodiment of this invention also provides a head-up display device, including any of the aforementioned reflector assemblies, a housing 6, and an image generation unit (not shown in the figure) disposed within the housing 6. A mounting base 2 is provided inside the housing 6. The base of the reflector assembly is detachably connected to the mounting base 2, and a locking mechanism 4 is detachably connected to the mounting base 2. The image generation unit generates an image, and the reflector assembly reflects the image. When the head-up display device is in operation, the image generation unit generates an image containing driving information and projects the image onto the reflector. The image is then reflected by the reflector 5 onto the windshield of the vehicle, and finally reflected through the windshield to the driver's eyes, allowing the driver to obtain driving information. This application does not limit the structural relationship between the housing 6 and the groove 21. In some embodiments, the housing 6 includes the groove 21, meaning the groove 21 is part of the housing 6. In other embodiments, the groove 21 and the housing 6 are independent components.
[0041] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
