Description
Technical Field
[0001] This utility model relates to the field of HUD display system technology, and more specifically, to a reflector bracket and a head-up display. Background Technology
[0002] A vehicle-mounted HUD (Head-Up Display) is a display system that projects driving information into the driver's line of sight through optical reflection, effectively reducing driver eye deviation and improving driving safety. As one of the core components of a HUD, the stability and adjustment precision of the reflector's axis directly determine the clarity and dynamic adaptability of the projected image.

Such designs lack elastic compensation mechanisms and are prone to problems such as rotation jamming, vibration noise, and image jitter due to assembly gaps, which seriously reduces the adjustment accuracy. The axial limiting of some rotating shafts relies on tension springs to apply pressure to the edge of the mirror to maintain stability, but this method is prone to causing local deformation of the mirror surface, affecting the imaging quality, and increasing the complexity of the mirror manufacturing process.

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] Please refer to Figure 1 and Figure 5This embodiment provides a reflector bracket 100, including a rotating shaft 110 and two elastic limiting members 120, which are respectively sleeved on opposite ends of the rotating shaft 110; the rotating shaft 110 is used to set a reflector 220, which is located between the two elastic limiting members 120; the elastic limiting members 120 have a first elastic part 121 and a second elastic part 122 spaced apart along the axial direction of the rotating shaft 110, and the first elastic part 121 and the second elastic part 122 are respectively attached to the outer wall of the rotating shaft 110.
[0031] Specifically, such as Figure 1 As shown, the reflector bracket 100 includes a rotating shaft 110 and two elastic limiting members 120. The rotating shaft 110 plays the role of supporting and positioning the reflector 220 in the entire reflector bracket 100 system. The elastic limiting members 120 not only fit on both ends of the rotating shaft 110, but also play a certain limiting role on the reflector 220 located in the middle from both sides, preventing the reflector 220 from moving axially on the rotating shaft 110 at will.
[0032] Existing reflector brackets mostly use rigid metal springs or fixed structures to axially limit the rotating shaft. Since these limiting components are not elastic, they are prone to problems such as rotation jamming, vibration noise and image jitter due to assembly gaps, which seriously reduces the adjustment accuracy.
[0033] To solve the above problem, please refer to Figure 2 and Figure 3 The elastic limiting member 120 of this application includes a first elastic part 121 and a second elastic part 122. When the rotating shaft 110 is subjected to external force and may undergo axial displacement, the first elastic part 121 and the second elastic part 122, by virtue of their own elasticity, can provide a reverse force to limit the displacement of the rotating shaft 110. For example, when vibration occurs during vehicle operation, causing the rotating shaft 110 to have an axial movement tendency, these two elastic parts will play a role, using their own elastic deformation to counteract this displacement tendency, thereby ensuring the stability of the reflector 220, and thus ensuring the clarity and stability of the projected image of the vehicle HUD system. Compared with the rigid metal spring or fixed structure in the prior art, this elastic limiting method can better adapt to assembly gaps and reduce rotational jamming, vibration noise, and image jitter problems.
[0034] While existing technologies also employ elastic elements to reduce rotational jamming, they typically involve axially mounting a tension spring on the rotating shaft 110 to apply pressure to the edge of the reflector 220. This method easily causes localized deformation of the mirror surface, affecting image quality and increasing the manufacturing complexity of the reflector 220. In contrast, this application directly provides a first elastic portion 121 and a second elastic portion 122 on the elastic limiting member 120, preventing localized deformation of the mirror surface and simplifying the manufacturing complexity of the reflector 220.
[0035] It should be noted that, as Figure 3 As shown, in one possible embodiment of this application, the elastic limiting member 120 further includes a connecting plate 123, the sidewalls of which are respectively connected to the first elastic part 121 and the second elastic part 122; the connecting plate 123 has a mounting hole 1231 for inserting a fixing member.
[0036] Specifically, such as Figure 3 As shown, the connecting plate 123 can connect the first elastic part 121 and the second elastic part 122, so that the first elastic part 121 and the second elastic part 122 can work together. When the rotating shaft 110 is affected by external force, through the transmission of the connecting plate 123, the two elastic parts can jointly apply an elastic limiting force to the rotating shaft 110, ensuring that the function of the entire elastic limiting member 120 is effectively realized.
[0037] Mounting holes 1231 are provided on the connecting plate 123 for fasteners to pass through. The fasteners can be common connectors such as bolts and rivets. By setting the connecting plate 123, the reflector bracket 100 can be installed inside the housing 210 of the head-up display 200, thereby improving the stability and reliability of the overall structure.
[0038] Compared with the prior art, this application can not only limit the axial movement of the rotating shaft 110 by setting the elastic limiting member 120, but also improve the rotational stability of the rotating shaft 110 through its own elasticity; the first elastic part 121 and the second elastic part 122 are directly set on the elastic limiting member 120, which will not cause pressure on the reflector 220, thus improving the reliability of the reflector bracket 100.
[0039] In one possible implementation of this application, such as Figure 2 As shown, the first elastic part 121 includes a first collar 1211 and a plurality of first elastic pressure plates 1212 connected to each other. The first collar 1211 is sleeved on the outer wall of the rotating shaft 110. The plurality of first elastic pressure plates 1212 are spaced apart on the outer wall of the rotating shaft 110 along the circumferential direction of the rotating shaft 110, and the first elastic pressure plates 1212 are disposed on the side of the first collar 1211 away from the reflector 220.
[0040] Specifically, such as Figure 2 As shown, the first elastic part 121 is part of the elastic limiting member 120 and is composed of a first collar 1211 and a plurality of first elastic pressure plates 1212.
[0041] The first ring 1211 is fitted onto the outer wall of the rotating shaft 110. It not only provides a basic mounting carrier for the first elastic part 121, allowing the entire first elastic part 121 to be firmly attached to the rotating shaft 110, but also provides preliminary protection and positioning for the rotating shaft 110 to a certain extent. Multiple first elastic pressure plates 1212 are distributed around the circumference of the rotating shaft 110, with intervals between them. This interval arrangement allows each pressure plate 1212 to work independently yet collaboratively when applying elastic force to the rotating shaft 110, adapting to external forces from different directions. The arrangement of multiple first elastic pressure plates 1212 allows for pre-tightening of the rotating shaft 110 of the reflector 220, eliminating any gaps in the fit of the rotating shaft 110. This application does not impose any limitation on the specific number of first elastic pressure plates 1212; the number can be 6, 4, 10, etc.
[0042] Optionally, the width of the first elastic pressure plate 1212 on the side closer to the first collar 1211 is greater than the width of the first elastic pressure plate 1212 on the side farther from the first collar 1211, and the width direction a is in the same direction as the circumferential direction of the rotating shaft 110, so that the first elastic pressure plate 1212 has a trapezoidal sheet structure.
[0043] The wider portion near the first collar 1211, due to its relatively large area, provides a more stable connection foundation when connected to the first collar 1211, making the connection between the first elastic pressure plate 1212 and the first collar 1211 more reliable. Simultaneously, the wider portion can better distribute pressure when subjected to external forces, enhancing the structural stability of the entire first elastic part 121. The narrower side, farther from the first collar 1211, while maintaining a certain elastic function, is relatively flexible, facilitating appropriate elastic deformation under external forces to effectively limit the movement of the rotating shaft 110.
[0044] Optionally, such as Figure 2 As shown, a pressure block 1213 is also provided on the outer wall of the first elastic pressure plate 1212. One end of the pressure block 1213 is fixedly connected to the first collar 1211. This connection method can effectively combine the first elastic pressure plate 1212 and the first collar 1211 more tightly, enhancing their collaborative working ability. When the rotating shaft 110 is subjected to external force, this connection structure can transmit force more stably, enabling the first elastic part 121 to better limit and buffer the rotating shaft 110, ensuring the stable installation of the reflector 220 on the rotating shaft 110, thereby ensuring that the projection effect of the vehicle HUD system is not affected.
[0045] It should be noted that, firstly, such as Figure 2As shown, the width of the side of the pressure block 1213 closest to the first collar 1211 is greater than the width of the side of the pressure block 1213 furthest from the first collar 1211, and the width direction a is in the same direction as the circumferential direction of the rotating shaft 110; the projected area of the pressure block 1213 is smaller than the projected area of the first elastic pressure plate 1212, wherein the projection direction is the stacking direction of the pressure block 1213 and the first elastic pressure plate 1212.
[0046] On the one hand, the wider side closer to the first ring 1211 can provide a more stable connection base, making the fixed connection between the pressure block 1213 and the first ring 1211 more reliable and better able to distribute pressure when subjected to external forces; on the other hand, the narrower side farther from the first ring 1211 is relatively flexible, which is conducive to the pressure block 1213 generating appropriate elastic deformation when subjected to external forces, and working together with the first elastic pressure plate 1212 to effectively limit and buffer the rotating shaft 110.
[0047] Furthermore, the projected area of the pressure block 1213 is smaller than that of the first elastic pressure plate 1212, which allows the pressure block 1213 to be reasonably arranged on the outer wall of the first elastic pressure plate 1212 without affecting the main function of the first elastic pressure plate 1212. In addition, while ensuring structural stability, it does not increase the weight and volume too much, which helps to optimize the design and improve the performance of the entire reflector bracket 100.
[0048] Second, preferably, each first elastic pressure plate 1212 is provided with a pressure block 1213; of course, it is also possible that some of the first elastic pressure plates 1212 are provided with pressure blocks 1213 to save on the production cost of the reflector bracket 100. The first elastic pressure plates 1212 provided with pressure blocks 1213 are disposed opposite to each other on the outer wall of the rotating shaft 110 to ensure that the rotating shaft 110 is subjected to uniform force.
[0049] In another possible embodiment of this application, the second elastic part 122 includes a second elastic pressure plate 1221, which is circumferentially disposed on the outer wall of the rotating shaft 110 along the circumferential direction of the rotating shaft 110; the inner wall of the second elastic pressure plate 1221 has a plurality of abutting protrusions 1221a spaced apart along the circumferential direction of the rotating shaft 110, and the abutting protrusions 1221a are used to press against the outer wall of the rotating shaft 110.
[0050] Specifically, the second elastic pressure plate 1221 is arranged around the circumference of the rotating shaft 110, so that the second elastic pressure plate 1221 can apply a uniform elastic force to the rotating shaft 110 in the circumferential direction. Multiple abutment protrusions 1221a are distributed on the inner wall of the second elastic pressure plate 1221. These abutment protrusions 1221a are arranged at intervals along the circumferential direction of the rotating shaft 110.
[0051] Each abutment protrusion 1221a directly contacts and applies pressure to the outer wall of the rotating shaft 110. When the rotating shaft 110 is subjected to external force and tends to displace, the abutment protrusion 1221a can generate frictional force and elastic reaction force to prevent the rotating shaft 110 from displacing by pressing against the outer wall of the rotating shaft 110. The coordinated work of multiple abutment protrusions 1221a enhances the limiting effect of the second elastic pressure plate 1221 on the rotating shaft 110, further improving the stability and reliability of the entire reflector bracket 100 system. It also allows for a more relaxed tolerance grade for the precision positioning hole, reducing processing costs.
[0052] Of course, in addition to the above-described implementation methods, such as Figure 3 As shown, the second elastic part 122 may further include a second collar 1222 and a plurality of second elastic pressure plates 1221; the second collar 1222 is sleeved on the outer wall of the rotating shaft 110 and located on the side of the first elastic part 121 near the reflector 220; the second collar 1222 includes a body 1222a and an extension plate 1222b, one end of the extension plate 1222b is connected to the body 1222a, and the other end extends along the axial direction of the rotating shaft 110 to connect with the first collar 1211, so that the second collar 1222... A receiving portion 1223 is formed between the extension plate 1222b and the first sleeve ring 1211. The receiving portion 1223 is located on opposite sides of the extension plate 1222b along the circumferential direction of the rotating shaft 110. The second elastic pressure plate 1221 extends along the circumferential direction of the rotating shaft 110 and is disposed in the receiving portion 1223. At least one end of the second elastic pressure plate 1221 is connected to the side wall of the extension plate 1222b. The inner wall of the second elastic portion 122 has an abutting protrusion 1221a, which is used to press against the outer wall of the rotating shaft 110.
[0053] Specifically, the second ring 1222 is fitted onto the outer wall of the rotating shaft 110, and it consists of a body 1222a and an extension plate 1222b. For example... Figure 3 As shown, the main body 1222a is the main part of the second ring 1222 fitted onto the outer wall of the rotating shaft 110. One end of the extension plate 1222b is connected to the main body 1222a, and then extends along the axial direction of the rotating shaft 110, eventually connecting with the first ring 1211. This connection method forms a receiving portion 1223 between the second ring 1222 and the first ring 1211. The connection of the extension plate 1222b enhances the structural stability between the first ring 1211 and the second ring 1222, making the entire elastic limiting member 120 more stable.
[0054] like Figure 3As shown, the second elastic pressure plate 1221 is distributed around the circumferential path of the rotating shaft 110 within the space of the receiving portion 1223. Furthermore, at least one end of the second elastic pressure plate 1221 is connected to the side wall of the extension plate 1222b. This connection method allows the second elastic pressure plate 1221 to be fixed within the receiving portion 1223. When the rotating shaft 110 is subjected to external force, the second elastic pressure plate 1221, through its connection with the extension plate 1222b, transmits the elastic force to the entire structure composed of the second collar 1222 and the first collar 1211, thereby effectively limiting the rotation of the shaft 110. The multiple second elastic pressure plates 1221 working collaboratively within the receiving portion 1223 further enhance the elastic limiting effect of the second elastic portion 122 on the rotating shaft 110.
[0055] like Figure 4 As shown, an abutting protrusion 1221a is provided on the inner wall of the second elastic pressure plate 1221. The abutting protrusion 1221a enhances the limiting effect of the second elastic pressure plate 1221 on the rotating shaft 110, further improving the stability and reliability of the entire reflector bracket 100 system. It can also appropriately relax the tolerance grade of the precision positioning hole and reduce the processing cost.
[0056] It should be noted that, in the embodiments of this application, this application does not impose any limitation on the number of extension plates 1222b, and the number of extension plates 1222b is at least one; when the number of extension plates 1222b is multiple, the multiple extension plates 1222b are evenly distributed on the side of the second ring 1222 close to the first ring 1211.
[0057] When there is only one extension plate 1222b, the second elastic pressure plates 1221 on the side walls of both sides of the extension plate 1222b can be connected to form a ring-like structure. When there are multiple extension plates 1222b, for example, when there are two extension plates 1222b, two receiving portions 1223 are formed accordingly, and each receiving portion 1223 can be provided with at least one second elastic pressure plate 1221. Similarly, the extension plates 1222b can also be set to three, four, etc., and the number of receiving portions 1223 and second elastic pressure plates 1221 can also be increased accordingly, as long as it can be ensured that multiple extension plates 1222b are evenly distributed on the side of the second ring 1222 close to the first ring 1211, so that the force on the rotating shaft 110 is uniform.
[0058] Another aspect of the embodiments of this application, such as Figure 6 As shown, a head-up display 200 is also provided, including a housing 210, a reflector 220 and a reflector bracket 100. The reflector 220 is disposed on the reflector bracket 100, and the reflector bracket 100 is fixedly disposed inside the housing 210.
[0059] Specifically, the housing 210 is the external protective structure of the entire head-up display 200. It provides a mounting base and protection for other internal components, resisting the impact of external factors such as dust and impacts on the internal components. The reflector 220 is an important component in the head-up display 200 responsible for reflecting images or information into the driver's field of vision. Its performance and positional accuracy play a crucial role in the display effect. The reflector bracket 100 is a component used to support and fix the reflector 220. It ensures that the reflector 220 maintains a stable position and orientation during operation, enabling the reflector 220 to accurately project information to the appropriate location.
[0060] The reflector 220 is mounted on the rotating shaft 110 of the reflector bracket 100, and the rotating shaft 110 can be fixedly connected to the housing 210 through the elastic limiting member 120. When the rotating shaft 110 rotates relative to the elastic limiting member 120, it can synchronously drive the reflector 220 to rotate to adjust the image position. The specific structure and beneficial effects of the elastic limiting member 120 have been described in detail above and will not be repeated here.
[0061] 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.
[0062] 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.
