[0042] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-4 The tube beam 100 according to a first aspect embodiment of the present invention is described.

[0043] like Figures 1-4 As shown, the tube beam 100 according to the first aspect of the present invention includes a tube beam body 1 and a reflective film (not shown).

[0044] Specifically, a reflective film is disposed on at least a portion of the surface of the tube beam body 1. The reflective film is adapted to reflect light to achieve the vehicle head-up display function. For example, the tube beam body 1 can be a conventional tube beam structure in the steering system of the vehicle 400. That is, other parts of the conventional tube beam can remain unchanged to ensure the function of the tube beam body 1 in the steering system 300, while a reflective film is disposed on a portion or all of the surface of the tube beam body 1. The reflective film can be applied or plated onto the aforementioned at least a portion of the surface. For example, the reflective film can be covered only on the surface of the tube beam body 1 facing the windshield 401 of the vehicle 400.

[0045] When the tube beam 100 is used in the display system 200 of the vehicle 400, the light emitted by the image generation unit 201 of the display system 200 can propagate to the reflective film, be reflected at the reflective film, and then propagate to the windshield 401. After secondary reflection, it propagates to the eyes of the driver or passenger, so that the driver or passenger in the vehicle can see a virtual image 2 that is the same as the image of the image generation unit 201 through the windshield 401, thus realizing the vehicle head-up display function (that is, the function of the vehicle head-up display system mentioned later in this invention, the display principle is as follows). Figure 5 (As shown). The virtual image 2 is formed on the outside of the windshield 401, and the driver or passengers inside the vehicle can see the floating virtual image 2 through the windshield 401.

[0046] This design has several advantages. First, by reusing the existing tube beam 100 structure (tube beam body 1) on the vehicle, only the surface of the tube beam body 1 needs to be coated with a reflective film. By utilizing the existing tube beam body 1 to achieve optical path modulation, the volume of the display system 200 can be reduced by more than 50%, thus reducing the space occupied by the display system 200 in the dashboard. Furthermore, by eliminating the processing and calibration steps for reflectors and mechanical rotating devices, the coating process for the reflective film is completed simultaneously with the manufacturing of the tube beam body 1, reducing production costs (mass production costs decrease by more than 30%) and providing an integrated, low-cost alternative to the display system 200. Second, it enables multiple uses for a single tube beam 100, enriching its functionality and improving its performance.

[0047] According to the first aspect of this utility model, the tube beam 100 achieves multiple uses, enriches its functionality, and improves its performance. Furthermore, by setting a reflective film on the tube beam body 1, optical path modulation is achieved using the existing tube beam body 1, reducing the space occupied by the display system 200 within the instrument panel. Moreover, the processing and calibration steps for the reflector, mechanical rotation device, and reflective film are eliminated; the coating process of the reflective film is completed simultaneously with the manufacturing of the tube beam body 1, reducing production costs and providing an integrated, low-cost alternative to the display system 200.

[0048] According to some embodiments of the present invention, at least a portion of the surface of the tube beam body 1 is formed as a curved surface or a plane.

[0049] For example, the upper surface of the tube beam body 1 can maintain its original planar structure or be curved. When the light emitted by the image generation unit 201 is reflected by the reflective film to the edge of the windshield 401 (e.g., the light-blocking area of ​​the windshield 401), the curvature at the edge is small, and at this time, at least part of the surface of the tube beam body 1 can be set as a planar surface. When the light emitted by the image generation unit 201 is reflected by the reflective film to the middle of the windshield 401 (e.g., the light-transmitting area of ​​the windshield 401), the curvature at the middle is large, and at this time, at least part of the surface of the tube beam body 1 can be set as a curved surface to adapt to the structure of the windshield 401, so that the driver or passenger can see a complete image.

[0050] According to some embodiments of the present invention, when at least a portion of the surface of the tube beam body 1 is formed as a curved surface, at least a portion of the surface of the tube beam body 1 is formed as a spherical surface, a cylindrical surface, or a free-form surface.

[0051] like Figure 2 and Figure 3As shown, at least a portion of the surface of the tube beam body 1 is formed as a freeform surface. The term "spherical surface" can be understood as a part of a sphere, and "cylindrical surface" can be understood as a part of the outer surface of a cylinder. That is, the shape of the aforementioned at least a portion of the surface of the tube beam body 1 can be a part of a sphere, a part of a cylinder, or a varying curved surface (e.g., a change in curvature or a change in bending direction). It should be noted that the aforementioned curved surface can be a surface concave towards the center of the tube beam body 1, or a surface convex towards the side away from the center of the tube beam body 1. Specifically, it can be defined based on the positional relationship between the tube beam 100, the image generation unit 201, and the windshield 401, as well as the shape of the windshield 401. Furthermore, this enriches the selection of curved surface shapes, allowing the tube beam 100 to be applicable to more application scenarios.

[0052] According to some embodiments of the present invention, when at least a portion of the surface of the tube beam body 1 is formed as a curved surface, the curved surface is a surface formed by the inward concavity of at least a portion of the surface of the tube beam body 1.

[0053] For example, in Figure 2 In the example, the side of the tube beam body 1 facing the windshield 401 is formed as an inwardly concave curved surface. With this configuration, the light from the image generation unit 201 diverges after being reflected by the reflective film, thus magnifying the image and making the image seen by the driver or passenger larger and clearer. Furthermore, the curved surface reflects and modulates the light, ensuring that the image seen by the driver after secondary reflection on the windshield 401 better matches the shape of the windshield 401, improving the occupant's experience. The specific light propagation path is: image generation unit 201 emits light → incident on the curved surface of the reflective film → reflected and modulated (magnified / collimated) by the curved surface → projected onto the windshield 401 → reflected into the driver's or passenger's field of vision to form a virtual image 2.

[0054] According to some embodiments of the present invention, the curvature of at least a portion of the surface of the tube beam body 1 is R, where R satisfies:

[0055] in, D is the distance between the image generation unit 201 and the reflective film, and θ is the reflection angle of the illuminated object.

[0056] For example, D can be understood as the distance between the image generation unit 201 and the reflection position on the reflective film, and the illuminated object can be understood as the windshield 401 of the vehicle 400. Of course, the illuminated object can also be other components that emit light secondaryly. Thus, by adjusting the distance between the image generation unit 201 and the reflective film, as well as the reflection angle of the illuminated object, the curvature of the surface can be determined, thereby making the formed virtual image 2 more compatible with the structure of the illuminated object, and making the image seen by the driver or passengers inside the vehicle clearer and more continuous. For example, the surface of the tube beam body 1 is processed into a concave surface with a preset curvature, and the radius of curvature matches the reflection angle requirement of the windshield 401, ensuring that light can be projected onto the windshield 401 after reflection. It should be noted that the above-mentioned curvature can also be understood as the curvature of the part of the surface where the light reflection position is located. That is, when the curvature of at least part of the surface of the tube beam 100 is not uniform, the curvature at the point on the tube beam 100 opposite to the reflection position of the reflective film only needs to meet the above requirements.

[0057] According to some embodiments of this utility model, at least a portion of the surface of the tube beam body 1 is a smooth, closed surface. The aforementioned "smooth, closed surface" can be understood as a continuous, complete, smooth curved surface, or a surface without gaps or other structures. Therefore, when the mounting angle of the image generation unit 201 changes, or when the angle of the light emitted by the image generation unit 201 changes, the light can be reflected to the illuminated object from any position on the aforementioned at least a portion of the surface. This allows the tube beam 100 to be applicable to various application scenarios and also enables adjustment of the image position seen by passengers passing through the illuminated object. Furthermore, smoothing and closing a single outer surface of the tube beam body 1 does not affect its basic function, allowing the tube beam 100 to be used normally in the steering system 300.

[0058] According to some other embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the tube beam body 1 includes the tube beam main body 11 and 111, the reflective substrate 111 is disposed on the main body 11 of the tube beam, and the reflective film is disposed on at least a portion of the surface of the reflective substrate 111.

[0059] For example, in Figure 3 and Figure 4In the example, the main body 11 of the tube beam can be understood as a tube beam structure in conventional technology. The reflective substrate 111 is connected to the main body 11 of the tube beam. The reflective film can be provided only on at least a portion of the side of the reflective substrate 111 away from the main body 11 of the tube beam, or it can be provided on the outer surface of the reflective substrate 111. With this configuration, during the production process of the tube beam 100, the reflective film can be first placed on the reflective substrate 111, and then the reflective substrate 111 can be connected to the main body 11 of the tube beam. This facilitates the adjustment of the shape of the aforementioned at least a portion of the surface of the reflective substrate 111 to adapt to the requirements of different scenarios. At the same time, the main body 11 of the tube beam can be mass-produced using conventional processes. Optionally, the shape of the reflective film is adapted to the shape of the reflective substrate 111.

[0060] According to some embodiments of the present invention, the main body 11 of the tube beam has a mating part (not shown in the figure), and the reflective substrate 111 is disposed on the mating part. For example, the side of the tube beam 100 facing the windshield 401 has a mating part, through which the reflective substrate 11 can be connected to the tube beam body 11. During the assembly of the tube beam 100, the reflective film can be first applied to the reflective substrate 11, and then the reflective substrate 11 can be installed at the mating part. This arrangement facilitates the connection between the tube beam body 11 and the reflective substrate 111, simplifying the assembly and use of the tube beam 100. Furthermore, the tube beam body 11 can be a traditional tube beam structure, allowing it to be used in the display system 200 without structural modifications, thus realizing the vehicle head-up display function.

[0061] According to some embodiments of this utility model, the area of ​​the reflective film is larger than the area of ​​the main body 11 of the tube beam. For example, the area of ​​the main body 11 of the tube beam can be understood as... Figure 4 The area at the junction of the main body 11 of the tube beam and the reflective substrate 111 is shown. That is, the area of ​​one side along the thickness direction of the main body 11 of the tube beam. Therefore, the area of ​​the reflective film can be set according to the usage requirements of the tube beam 100, so that the area of ​​the reflective film is not limited by the area of ​​the main body 11 of the tube beam. Furthermore, while the reflective substrate 11 provides support for the reflective film, it allows light to be reflected by a larger area of ​​the reflective film, enabling more flexible adjustment of the virtual image 2 seen by the driver or passenger.

[0062] According to some embodiments of this utility model, the reflectivity of the reflective film is r, where r satisfies: 90% ≤ r ≤ 99%. Therefore, by setting a reflective film with high reflectivity, light utilization and conversion efficiency can be increased, thereby improving the visual effect of the display system 200 and enhancing the user experience. The high-reflectivity reflective film can be formed using vacuum evaporation or magnetron sputtering processes, and light modulation is achieved through the reflective film and its tightly curved surface design.

[0063] According to some embodiments of this utility model, the thickness of the reflective film is d, where d satisfies: 100nm≤d≤500nm.

[0064] For example, the thickness of the reflective film can be understood as the dimension in the assembly direction between the reflective film and the tube beam body 1. When the thickness of the reflective film is less than 100nm, the film is too thin, which is not conducive to light propagation and the coating of the reflective film, increasing the difficulty of the process. When the thickness of the reflective film is greater than 500nm, the film is too thick, and the performance improvement is not significant while increasing the amount of material used. Therefore, by setting the thickness d of the reflective film to satisfy 100nm≤d≤500nm, the thickness of the reflective film is moderate, which is conducive to light reflection and the processing of the reflective film, thus facilitating the production of the tube beam 100.

[0065] According to some embodiments of this utility model, the reflective film is a high-temperature resistant and / or corrosion-resistant reflective film.

[0066] For example, the reflective film can withstand high temperatures of 100℃ (e.g., it can be used in temperatures ranging from -40℃ to 100℃), allowing it to be applied in various temperature environments. This improves the film's aging resistance and extends its service life, thereby extending the service life of the tube beam 100. It also facilitates the coating process. Furthermore, the aforementioned corrosion resistance includes resistance to acids and alkalis, hand sweat, salt spray, and other chemicals, ensuring long-term stable use and further extending the film's service life.

[0067] According to some embodiments of this utility model, the reflective film is a metal reflective film. Thus, through optical interference or the reflective properties of metal, light is deflected within the visible light range (400-700nm), ensuring that the light received by the human eye does not experience color distortion, while also adapting to the complex environment of the vehicle.

[0068] According to some embodiments of this utility model, the reflective film is an aluminum film or a gold film. Therefore, the reflective film has a good reflective effect, thereby improving the visual effect for the driver or passengers. Furthermore, aluminum film is low in cost, easy to process, and has high visible and near-infrared reflectivity, offering excellent cost-effectiveness. Gold film has extremely high infrared reflectivity and strong stability, and is resistant to oxidation and corrosion, making it suitable for use in harsh environments such as high temperature and high humidity, thus improving the applicability of the reflective film.

[0069] The display system 200 according to the second aspect embodiment of the present utility model, such as Figure 6 As shown, it includes a tube beam 100 according to the first aspect embodiment described above.

[0070] According to the second aspect embodiment of the present invention, the display system 200, employing the aforementioned tube beam 100, reduces the number of components in the display system 200, thereby reducing the space occupied by the display system 200 within the dashboard of the vehicle 400, which is beneficial for the arrangement and installation of components within the dashboard. Furthermore, compared to conventional vehicle head-up displays, the processing and calibration steps for reflectors and mechanical rotating devices are eliminated, and the coating process for the reflective film can be completed simultaneously with the tube beam body 1, reducing operational steps, thereby reducing the number of components in the display system 200, lowering the processing cost of the display system 200, and reducing processing difficulty. For example, the display system 200 can be a vehicle head-up display system, or it can be a display on the vehicle 400 or other instruments; no specific limitation is made here.

[0071] According to some embodiments of this utility model, such as Figure 6 As shown, the display system 200 also includes an image generation unit 201. The light emitted by the image generation unit 201 illuminates the reflective film of the tube beam 100 and is reflected by the reflective film to the illuminated object.

[0072] For example, the image generation unit 201 can be installed inside the dashboard and located on the driver-facing side of the tube beam 100. The image generation unit 201 is rotatable relative to its installation position to adjust the angle of the emitted light. The image generation unit 201 can be configured as an optical engine. When the display system 200 is operating, the light emitted by the image generation unit 201 illuminates the reflective film of the tube beam 100, and after reflection, illuminates an object such as the windshield 401 for secondary reflection before reaching the eyes of the driver or passenger. Thus, the user sees the same image as that emitted by the image generation unit 201. Therefore, the configuration of the image generation unit 201 ensures the ability to change and switch between images, facilitating user adjustment of the display. For example, the image generation unit 201 communicates with the vehicle 400's dashboard to synchronize the image display. It should be noted that the image generation unit 201 can be a pre-purchased display device or can be adjusted according to usage.

[0073] According to some embodiments of the present invention, the image generation unit 201 includes a light source and a display screen. For example, the light source can be located on the side of the display screen away from the tube beam 100. When the image generation unit 201 is working, the light emitted by the light source after illuminating the display screen illuminates the reflective film to ensure the transmission of the image on the display screen.

[0074] Optionally, the light source may include white light.

[0075] When the light source is white light, which is essentially a mixture of multiple wavelengths of light (red, green, and blue are the three primary colors, i.e., RGB), setting the light source to white light can maximize the reproduction of the image and picture quality on the display screen, thereby reducing the interference of the light source on the display screen and further improving the display performance and picture quality of the display system 200. It should be noted that the color of the light source can be detected using a spectral measurement device. For example, when the detected color coordinate range of the light source is 0.32-0.34, the light source can be considered white light.

[0076] According to some embodiments of the present invention, the display screen includes a thin-film transistor display screen, a digital light processing display screen, or a microdisplay chip display screen.

[0077] The display screen includes FTF (Thin Film Transistor) screens, DLP (Digital Light Processing) screens, or LCOS (Liquid Crystal on Silicon) screens. TFT is the core technology for driving pixels, and its core advantages lie in the fine detail, response speed, and practicality of flat-panel displays. DLP uses a DMD chip (million-micromirror array) to reflect light for imaging, and its core advantages are high brightness, high contrast, and portability in projection scenarios. LCOS combines "liquid crystal light control + silicon-based chip driving," and its core advantages are high resolution, high image quality, and low power consumption in miniaturized scenarios. Furthermore, all of the above display screens can ensure a good visual viewing experience for the driver and passengers within 400 meters of the vehicle, enhancing the user experience of the display system.

[0078] According to some optional embodiments of this utility model, the white light includes LED white light and / or white laser. This configuration can reproduce the true colors of the display screen and adapt to various types of screen content. Furthermore, the light is close to natural light, without the strong stimulation of monochromatic light, reducing eye strain during prolonged viewing and improving the clarity of image details. In addition, LED white light is low-cost and portable, which is more conducive to the installation and production of the display system 200. White laser has high brightness and a wide color gamut, remaining clear even in strong light environments, further enhancing the image quality.

[0079] According to some embodiments of this utility model, the display system 200 is a vehicle head-up display system. Therefore, road information, speed information, surrounding environment information, and even entertainment interaction information from the dashboard can be projected onto the driver's front through the display system 200, allowing the driver to raise their line of sight and significantly improving driving safety. Moreover, it is easy to use, has good image quality, and further enhances the user experience.

[0080] The steering system according to a third aspect of the present invention includes a tube beam 100 according to the first aspect of the present invention.

[0081] According to the third aspect embodiment of the present invention, the steering system 300, by employing the aforementioned tube beam 100, allows a portion of the tube beam 100 to be used as part of the display system 200. This enables the tube beam 100 to perform steering functions while also facilitating the display of the screen in the display system 200, thus enriching the functionality of the steering system 300 and improving its performance. For example, in conjunction with... Figure 6 The steering system 300 includes a steering column 301 and a tube beam 100. One end of the steering column 301 is connected to the steering wheel (not shown in the figure), and the steering column 301 is connected to the tube beam 100. The tube beam 100 can be used to fix the steering column 301 so as to facilitate the normal use of the steering column 301.

[0082] The vehicle 400 according to the fourth aspect of the present invention includes the tube beam 100 according to the first aspect of the present invention, or the display system 200 according to the second aspect of the present invention, and / or the steering system 300 according to the third aspect of the present invention.

[0083] According to the fourth aspect embodiment of the present utility model, the vehicle 400, by adopting the above-mentioned tube beam 100, display system 200, or steering system 300, has a richer function. While realizing the steering operation of the steering system 300, it also helps to reduce the volume occupied by the display system 200 in the dashboard, making the installation of the display system 200 more convenient and improving the space utilization rate in the dashboard, thereby further improving the performance of the vehicle 400 and enhancing the driver's driving experience.

[0084] According to some embodiments of this utility model, refer to Figure 6 The vehicle 400 also includes a windshield 401 with a visible area. Light emitted from the image generation unit 201 of the display system 200 is irradiated onto the reflective film of the tube beam 100 and reflected by the reflective film to the visible area of ​​the windshield 401.

[0085] With this configuration, light reflected by the reflective film can propagate to the windshield 401, and after secondary reflection by the windshield 401, it reaches the eyes of the driver or passenger. Thus, the windshield 401 serves as a carrier for light propagation, and also allows the driver or passenger inside the vehicle to see the virtual image 2 formed on the outside of the windshield 401 through its visible area. Furthermore, it does not affect the normal functioning of the windshield 401, enriching its functionality and improving its performance.

[0086] According to some embodiments of the present invention, the windshield 401 includes a light-transmitting area, and a visible area is formed in the light-transmitting area. And / or, the windshield 401 includes a light-shielding area, and a visible area is formed in the light-shielding area.

[0087] For example, the windshield 401 can be configured in the following ways: First, the entire windshield 401 is a light-transmitting area, and the visible area is formed within the light-transmitting area. Second, a portion of the windshield 401 is a light-blocking area, and the visible area is formed within the light-blocking area. Third, most of the windshield 401 is a light-transmitting area, and the outer periphery of the light-transmitting area is a light-blocking area. In this case, the visible area can be entirely formed within the light-transmitting area, entirely formed within the light-blocking area, or partially formed within the light-blocking area and partially formed within the light-transmitting area.

[0088] This configuration allows the driver and passengers inside the vehicle to see the formed virtual image 2 through both the shaded and translucent areas. This expands the visible area and the display options of the display system 200, further enhancing the visual experience for both drivers and passengers and making the display system 200 more adaptable to various angles and scenarios. Furthermore, when the visible area is formed within the shaded area, the shaded area not only reduces interference from external light on the virtual image formation but also increases contrast, resulting in a clearer image and a better visual experience for the driver and passengers.

[0089] According to some embodiments of this utility model, when the visible area is formed in the light-transmitting area, a ghosting correction element is provided inside the windshield 401. Since the windshield 401 is typically transparent glass, with the light-transmitting area being completely transparent, and the windshield 401 has a certain thickness, light incident on the windshield 401 will be reflected on both the inner and outer surfaces, resulting in ghosting. Therefore, by adding a ghosting correction element between the layers of the windshield 401, ghosting correction can be achieved, making the view clearer for the driver and passengers inside the vehicle, and further improving driving safety.

[0090] According to some embodiments of this utility model, the ghosting correction element is a wedge-shaped angle film.

[0091] For example, wedge-shaped corner films can be directly purchased and installed in the interlayer of the windshield 401. This precisely solves the problem of image shift and ghosting that often occurs in laminated glass. Furthermore, the wedge-shaped corner film, through its pre-designed micro-wedge structure, can specifically compensate for differences in light refraction, eliminating ghosting from an optical perspective, with a direct and precise correction effect. In addition, the wedge-shaped corner film is extremely thin (typically on the micrometer scale), and when applied to the windshield 401 or its interlayer, it hardly changes the overall thickness, light transmittance, or structural strength of the glass, ensuring clear visibility without compromising the original safety protection (shatterproof, splashproof) and durability of the laminated glass.

[0092] According to some embodiments of this utility model, a ceramic coating is provided in the light-shielding area. Here, "light-shielding area" can be understood as a portion of the windshield 401 where transparency is reduced; for example, it can be formed by applying a colored film layer. The light-shielding area can be formed by screen printing to create a colored ceramic coating, which can be sandwiched within the layers of the windshield 401, or it can be manufactured as a single, integral windshield 401 with a light-shielding area through a high-temperature sintering process. Thus, the light-shielding area not only reflects light as a light-transmitting area but also blocks some of the strong light from outside the vehicle, thereby alleviating driver visual fatigue and light stimulation.

[0093] According to some embodiments of the present invention, the windshield 401 is laminated glass or tempered glass.

[0094] With this design, when the windshield 401 is laminated glass, the safety performance of laminated glass is excellent. For example, if laminated glass breaks, the PVB (polyvinyl butyral) film in the middle will hold the fragments together, preventing them from flying and causing injury. Tempered glass breaks into small, blunt-edged particles, significantly reducing the risk of cuts and impact injuries. In addition, tempered glass has high hardness, strong impact resistance, and resistance to temperature changes (such as rapid temperature changes that prevent cracking), making it suitable for complex road conditions. Moreover, the mechanical strength of tempered glass is 3-5 times that of ordinary glass, making it less prone to breakage from minor impacts. Furthermore, both laminated glass and tempered glass can achieve secondary reflection of light after reflection by the reflective film, ensuring the normal display of the display system 200.

[0095] According to some embodiments of the present invention, the windshield 401 is a front windshield.

[0096] This setup eliminates the need for users to look down at the dashboard, keeping their gaze primarily on the road ahead. This significantly reduces time spent looking away from the road, lowering the risk of accidents caused by distraction. Furthermore, key information such as vehicle speed, navigation guidance, and driver assistance prompts are projected directly into the driver's field of vision, overlaid with road conditions, allowing the driver to quickly receive information without shifting their visual focus. Additionally, the windshield is a fixed surface directly facing the driver's line of sight, ensuring stable information placement, unobstructed by other components inside the vehicle, and highly adaptable to various lighting conditions (some models feature automatic dimming), providing clear visibility both day and night. It also avoids neck fatigue caused by frequent head tilting, making long drives more comfortable, while simultaneously creating a high-tech feel and enhancing driving convenience. It should be noted that the windshield can also be positioned at other locations within the vehicle (400mm) for passengers to use the display system (200mm).
