Description

Technical Field

[0001] The utility model relates to the field of automobile electronics, and in particular to a HUD image display unit fixing device. Background Art

[0002] A head-up display, also known as a head-up display or HUD, is a driver-centric, blind-operated, multi-function instrument panel that projects driving information such as speed and navigation onto the windshield in front of the driver, allowing the driver to see the navigation and speed information without lowering or turning his head.

[0003] Most of the current HUD products use image display units with screens. As the most important component of the image display unit, the screen is required to be fixed stably, easy to install, and have clear images. There are usually two existing screen assembly methods: 1. The screen and the bracket are snap-fitted. The disadvantage is that the screen and the bracket are elastically matched, and the bracket applies force directly to the screen, which will cause slight shaking of the screen and yellowing of the screen, affecting the image quality. 2. The screen and the bracket are fixed by glue. The disadvantage is that the screen and the bracket are directly fixed, and the deformation of the bracket will be directly transmitted to the screen, which can easily cause the screen to yellow and affect the image quality; and there are obvious sharp edges around the borderless screen, which can easily increase the risk of worker injury. Utility Model Content

[0004] In view of this, the utility model provides a HUD image display unit fixing device which can improve the force applied to the screen and avoid problems such as deformation and yellowing of the screen.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A HUD image display unit fixing device comprises a bracket, a screen panel and a glass panel, wherein the screen panel is fixedly attached to the glass panel and is located between the bracket and the glass panel, and at least two blank areas are provided on the glass panel, wherein the blank areas are the distances between the edges of the glass panel and the edges of the screen panel; a plurality of positioning blocks are provided on the bracket, the blank areas are fixed on the positioning blocks, and there is a gap between the screen panel and the bracket.

[0007] In the above technical solution, the blank areas on the glass panel are fixed by multiple positioning blocks on the bracket, ensuring the precise positioning of the glass panel and the screen panel during the assembly process. In addition, the arrangement of the glass panel and the blank areas enables the screen panel not to contact the bracket, thereby improving the stress on the screen panel. As a result, the screen panel is neither affected by the force applied by the bracket nor by the deformation of the bracket, effectively improving the problem of screen panel yellowing and enhancing the imaging quality. Moreover, due to the presence of the blank areas, the sharp edges of the screen panel can be effectively avoided, preventing damage to the operators during assembly.

[0008] Optionally, in a possible implementation, the blank areas are located at the edges on the opposite sides of the glass panel, and each blank area corresponds to one or more of the positioning blocks.

[0009] The above arrangement of the blank areas and the positioning blocks can, on the one hand, make the glass panel more stably fixed on the bracket and facilitate positioning and installation, and on the other hand, the combined design of the blank areas and the positioning blocks helps to optimize the stress distribution. When the HUD image display unit is subjected to external forces, the stress can be more evenly distributed to each positioning block, avoiding damage or deformation caused by local stress concentration, thereby extending the service life of the HUD system and improving its reliability.

[0010] Optionally, in a possible implementation, the positioning block is an "L"-shaped block structure.

[0011] In the above technical solution, the positioning block with an "L"-shaped structure has two perpendicular contact surfaces, facilitating the assembly and cooperation with the glass panel, resulting in a larger contact area between the glass panel and the positioning block, thus greatly enhancing the stability and firmness of the fixation, and also being more convenient for subsequent disassembly and maintenance.

[0012] Optionally, in a possible implementation, the bracket is a frame-type structure with a cavity and an open top, and multiple positioning blocks are spaced apart and distributed on the top edge of the bracket, and the screen panel is placed inside the cavity.

[0013] In the above technical solution, the frame-type structure of the bracket and the open-top design provide a closed and safe installation environment for the screen panel. The screen panel is placed inside the cavity, which can not only effectively prevent dust, moisture, and other pollutants from entering, but also reduce the impact of external shocks and vibrations on the screen panel, thereby extending its service life.

[0014] Optionally, in a possible implementation, the glass panel and the screen panel are bonded by an adhesive.

[0015] In the above technical solution, the multiple connection methods provided enable technicians to select the most suitable connection method according to specific application scenarios, installation conditions, and cost budgets. This flexibility not only meets diverse installation requirements but also improves installation efficiency and adaptability.

[0016] Optionally, in a possible implementation, the blank area and the bracket are adhesively bonded with an adhesive or snap-connected with a buckle.

[0017] In the above technical solution, the connection between the glass panel and the bracket is made more flexible by the multiple connection methods provided. All of the above multiple connection methods can stably fix the glass panel on the bracket, ensuring both stability and meeting the requirements of different materials.

[0018] Optionally, in a possible implementation, both the screen panel and the glass panel are rectangular structures, and the size of the glass panel is larger than that of the screen panel and can completely cover the screen panel.

[0019] In the above technical solution, since the size of the glass panel is larger than that of the screen panel, it can completely cover the screen panel to provide additional protection. This design not only prevents the screen panel from being directly exposed to potential threats such as dust, water vapor, scratches, and impacts in the external environment but also improves the durability and service life of the screen panel.

[0020] Optionally, in a possible implementation, the four corners of the glass panel are all rounded.

[0021] In the above technical solution, the rounded corner design can effectively reduce the risk of damage when the glass panel is impacted or collided. Compared with the right-angle design, the rounded corners can disperse the impact force, thus improving overall safety. And the rounded corner design makes the edges of the glass panel smoother, reducing the discomfort or risk of scratches that users may experience when touching or wiping.

[0022] Optionally, in a possible implementation, the glass panel is a sapphire transparent glass plate.

[0023] In the above technical solution, sapphire has high hardness and wear resistance to effectively resist scratches, abrasion, and various physical damages that may be encountered in daily use. And it also has high thermal conductivity, which helps to dissipate heat quickly, reduce the heat accumulation generated by the screen panel during long-term operation, and thus maintain the stable operation of the system and extend the service life.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Usually, the components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application to be protected, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0034] Please refer to Figures 1-5, this embodiment provides a fixing device for a HUD image display unit, including a bracket 1, a screen panel 2, and a glass panel 3. The screen panel 2 is fixedly attached to the glass panel 3, and the screen panel 2 is located between the bracket 1 and the glass panel 3. That is, the screen panel 2 is fixedly installed on the bracket 1 through the glass panel 3. There are at least two blank areas 31 on the glass panel 3, and the blank area 31 is the distance between the edge of the glass panel 3 and the edge of the screen panel 2. There are multiple positioning blocks 4 on the bracket 1, and the blank area 31 is fixed on the positioning blocks 4. There is a gap 5 between the screen panel 2 and the bracket 1. Among them, the blank area 31 on the glass panel 3 is fixed on the positioning blocks 4, so that both the glass panel 3 and the screen panel 2 can be fixed on the bracket 1, and the screen panel 2 never contacts the bracket 1, so that the bracket 1 will not affect the screen panel 2.

[0035] In this embodiment, the blank area 31 on the glass panel 3 is fixed by multiple positioning blocks 4 on the bracket 1, ensuring the precise positioning of the glass panel 3 and the screen panel 2 during the assembly process. In addition, the setting of the glass panel 3 and the blank area 31 can prevent the screen panel 2 from contacting the bracket 1, thereby improving the force on the screen panel 2. The screen panel 2 is neither affected by the force exerted by the bracket 1 nor affected by the deformation of the bracket 1. In this way, the problem of the screen panel 2 turning yellow can be effectively improved, and the imaging quality can be improved. And due to the existence of the blank area 31, the sharp edges of the screen panel 2 can also be effectively avoided, so that the damage to the operator caused by the sharp edges can be effectively avoided during assembly.

[0036] Please refer to Figure 5 , in this embodiment, the blank areas 31 are located at the edges on the opposite sides of the glass panel 3, and each blank area 31 corresponds to one or more positioning blocks 4. The two relatively arranged blank areas 31 can make the force on the glass panel 3 more balanced, that is, the force on the glass panel 3 can be effectively dispersed.

[0037] The arrangement of the above-mentioned blank area 31 and the positioning block 4 can, on the one hand, make the glass panel 3 more stably fixed on the bracket 1 and facilitate positioning and installation. On the other hand, the combined design of the blank area 31 and the positioning block 4 helps to optimize the stress distribution. When the HUD image display unit is subjected to an external force, the stress can be more evenly dispersed to each positioning block 4, avoiding damage or deformation caused by local stress concentration, thereby extending the service life of the HUD system and improving its reliability.

[0038] Please refer to Figure 6, It should be noted that the positioning block 4 in this embodiment is an "L"-shaped block structure. The "L"-shaped positioning block 4 has two perpendicular contact surfaces, which is convenient for assembling and cooperating with the glass panel 3, enabling the glass panel 3 and the positioning block 4 to have a larger contact area, thus greatly enhancing the stability and firmness of fixation, and at the same time making subsequent disassembly and maintenance more convenient.

[0039] Of course, as another implementation method, the positioning block 4 can also be a rectangular block structure, and the glass panel 3 can be directly fixed on the surface of the positioning block 4. Or, the positioning block 4 can be a block structure in the shape of a Chinese character "pin", which has the same function as the "L"-shaped structure but has higher strength.

[0040] In this embodiment, the bracket 1 is a frame-type structure with a cavity and an open top. A plurality of positioning blocks 4 are spaced apart and distributed on the top edge of the bracket 1, and the screen panel 2 is placed in the cavity. The cavity can be used to place other electronic components at the same time, such as circuit boards and power supplies.

[0041] The frame-type structure and the open-top design of the bracket 1 in this embodiment provide a closed and safe installation environment for the screen panel 2. The screen panel 2 is placed in the cavity, which can not only effectively prevent dust, water vapor and other pollutants from entering, but also reduce the impact of external shocks and vibrations on the screen panel 2, thereby extending its service life. In addition, the frame-type structure of the bracket 1 makes the installation process of the screen panel 2 simpler and more intuitive. The operator only needs to align the screen panel 2 with the opening of the bracket 1 and then fix it using the positioning block 4, which can reduce the installation steps and difficulty and improve the installation efficiency.

[0042] In this embodiment, the glass panel 3 and the screen panel 2 are bonded by an adhesive. In addition, the blank area 31 and the bracket 1 are bonded by an adhesive or clamped by a buckle. Among them, the blank area 31 is connected to the positioning block 4 on the bracket 1.

[0043] The various connection methods provided in this embodiment enable technicians to select the most suitable connection method according to specific application scenarios, installation conditions and cost budgets. For example, adhesive bonding can provide strong adhesion to ensure the close fit between the screen panel 2 and the glass panel 3; snap clamping provides a stable connection through mechanical locking. This flexibility not only meets diverse installation requirements but also improves installation efficiency and adaptability. And the various connection methods provided can also make the connection between the glass panel 3 and the positioning block 4, or the connection between the glass panel 3 and the screen panel 2 more flexible, and the above-mentioned various connection methods can all stably fix the glass panel 3 on the positioning block 4, ensuring both stability and meeting the requirements of different materials.

[0044] In this embodiment, both the screen panel 2 and the glass panel 3 are rectangular structures. The size of the glass panel 3 is larger than that of the screen panel 2 and can completely cover the screen panel 2. Since the size of the glass panel 3 is larger than that of the screen panel 2, it can completely cover the screen panel 2 to provide additional protection. This design not only prevents the screen panel 2 from being directly exposed to potential threats such as dust, moisture, scratches, and impacts in the external environment, but also improves the durability and service life of the screen panel 2.

[0045] In this embodiment, the rectangular screen panel 2 and glass panel 3 are taken as examples. The glass panel 3 completely covers the screen panel 2. The four side edges of the glass panel 3 can extend relative to the four side edges of the screen panel 2, or only the opposite two sides can extend while the other two sides are flush, that is, there can be four blank areas 31 or two blank areas 31. The sizes and widths of the blank areas 31 can be the same or different, and can be designed according to actual needs. It can be understood that the installation of the glass panel 3 can be completed by simply placing the two opposite blank areas 31 on the corresponding positioning blocks 4, which is simple and convenient.

[0046] It should be noted that the four corners of the glass panel 3 are all rounded. The rounded corner design can effectively reduce the risk of damage when the glass panel 3 is impacted or collided. Compared with the right-angle design, the rounded corners can disperse the impact force, thus improving the overall safety. And the rounded corner design makes the edge of the glass panel 3 smoother, reducing the discomfort or risk of scratching that may occur when the user touches or wipes it.

[0047] The glass panel 3 of this embodiment is a sapphire transparent glass plate. Sapphire has high hardness and wear resistance, which can effectively resist scratches, abrasions, and various physical damages that may be encountered in daily use. And it also has high thermal conductivity, which helps to dissipate heat quickly, reduce the heat accumulation generated by the screen panel 2 during long-term operation, and thus maintain the stable operation of the system and extend the service life.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present utility model.

[0049] Furthermore, the terms "first" and "second" are used for descriptive purposes only and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.
