Description

Technical Field

[0001] This application relates to the field of optical technology, and in particular to a lens, a head-up display device, and a vehicle. Background Technology

[0002] A head-up display (HUD) is a driver assistance device that projects important information such as speed and navigation onto the windshield in front of the driver using optical reflection. This eliminates the need for the driver to look down at the instrument panel, improving driving safety and convenience. The HUD lens is a crucial component, reflecting the light from the image generation unit onto the windshield.

[0003] In practical applications, HUD lenses are susceptible to interference from backlighting, resulting in stray light. Under strong sunlight, external sunlight shines through the windshield onto the edges of the HUD lenses. Due to manufacturing limitations, the lens edges often cannot achieve the ideal design during injection molding, resulting in small rounded corners of about 0.2mm. When exposed to sunlight, these corners become bright spots that are reflected through the windshield into the eye area, producing stray light and impairing image quality. Currently, the main solution is to add additional blocking components, such as sun visors, lens hoods, or side blocking strips, to reduce stray light generation.

[0004] In implementing the embodiments of this application, the inventors discovered that additional obstructing components not only increase the complexity and cost of the head-up display system, but also obstruct the driver's field of vision, affecting the driver's comprehensive observation of the road conditions ahead.

[0031] The present application will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present application, but do not limit the present application in any way. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present application. These all fall within the protection scope of the present application.

[0032] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0033] It should be noted that, unless there is a conflict, the various features in the embodiments of this application can be combined with each other, all of which are within the protection scope of this application. Furthermore, although functional modules are divided in the device schematic diagram, in some cases, they can be divided differently from those in the device. In addition, the terms "first" and "second" used herein do not limit the data or execution order, but only distinguish between identical or similar items with essentially the same function and effect.

[0034] In the head-up display device, please refer to Figure 1 and Figure 2 The image light generated by image generation unit 1 is reflected by lenses 2 and 3 and projected onto the windshield 4. The windshield 4 reflects the light into the eye box area 5, allowing the driver to observe clear image information. If backlighting occurs, firstly, during the design process, the edges of the lenses are often sharp angles. However, in actual injection molding, these angles often cannot achieve the ideal design, resulting in a small rounded corner of about 0.2mm. This small rounded corner will create bright spots and stray light when backlighting occurs. Secondly, refer to... Figure 2 Due to the issue of reflective coatings being applied to non-imaging areas during lens manufacturing, especially to the lens edges, stray light can be generated when sunlight backflow occurs, as the edges reflect sunlight. Please refer to [link to relevant documentation]. Figure 1 Sunlight will pass through the windshield 4 and shine onto the edge of the lens 3. The edge of the lens 3 reflects or converges the sunlight, causing the light to be reflected back through the windshield 4 and then enter the eye box area 5, affecting the image quality. Please refer to [link / reference]. Figure 2 When sunlight passes through the windshield 4, it shines on the edge of the lens 3. The edge of the lens 3 reflects the sunlight, causing the sunlight to enter the propagation path of the image light, resulting in the image light overlapping with the sunlight, which reduces the clarity and visibility of the image.

[0035] To improve the above-mentioned technical problems, this application provides a lens 100, a head-up display device, a vehicle, and a method for manufacturing the lens 100, thereby reducing the risk of stray light appearing at the edge of the lens 100 and improving image quality.

[0036] In the first aspect, embodiments of this application provide a lens 100, please refer to... Figures 3 to 5 The lens 100 includes a lens substrate 10 and a reflective film 20.

[0037] In some embodiments, please refer to Figure 3 and Figure 5 The lens substrate 10 includes a first surface 11 and a second surface 12 disposed opposite to each other. The first surface 11 is provided with a mounting area 111 and an edge area 112. The mounting area 111 is used to mount the reflective film 20, and the edge area 112 is disposed around the mounting area 111. The edge area 112 is provided with a first texture, which at least partially covers the edge area 112. The first texture is used to absorb light that shines on the edge area 112, thereby reducing the risk of stray light being formed due to reflection from the edge area 112.

[0038] In some embodiments, the first texture completely covers the edge region 112 so that when light from different incident angles strikes the edge region 112, it can effectively diffuse the light and further reduce the generation of stray light.

[0039] In some embodiments, the first texture is one or more fine structures such as serrated, wavy, or dot-matrix patterns. In some embodiments, the first texture is evenly distributed in the edge region 112, which not only ensures light absorption but also improves the overall aesthetics of the lens 100. In some embodiments, the first texture is periodically distributed in the edge region 112, which is beneficial to the consistency and stability of the first texture.

[0040] In some embodiments, please refer to Figure 3 and Figure 5 A reflective film 20 is disposed in the mounting area 111 to form a reflective area of ​​the lens 100. This reflective area is used to reflect preset incident light to a preset target area. The reflective film 20 is made of an optical material with high reflectivity and low absorption characteristics, such as one or more metal films like aluminum films and dielectric films, depending on the specific application requirements. In some examples, in head-up display applications, the reflective area formed by the reflective film 20 and the mounting area 111 is used to reflect image light from the image generation unit onto the windshield.

[0041] In some embodiments, the edge region 112 is an arc surface, with one end of the arc surface away from the mounting region 111 connected to the second surface 12, making the transition between the edge region 112 and the second surface 12 smoother and reducing the risk of light focusing caused by sharp edges. At the same time, the arc surface can provide a wider reflection angle, allowing the light illuminating the edge region 112 to be more fully absorbed by the first texture.

[0042] In some embodiments, the width of the projected area of ​​the edge region 112 along the direction from the first surface 11 to the second surface 12 is within a first preset range. In some examples, the first preset range is 0.2 mm to 0.5 mm. In some examples, the first preset range is 0.5 mm to 1 mm. Of course, the first preset range can also be greater than 1 mm, depending on the actual situation, and is not limited here.

[0043] In some embodiments, please refer to Figure 3 The first surface 11 is further provided with an isolation region 113, which is disposed between the mounting region 111 and the edge region 112. The isolation region 113 surrounds the mounting region 111, and the edge region 112 surrounds the isolation region 113. The isolation region 113 isolates the edge region 112 from the mounting region 111 used to mount the reflective film 20, so as to avoid direct contact between the edge of the reflective film 20 and the edge region 112 during processing or use, thereby preventing stray light from being generated due to the reflective film 20 entering the edge region 112, and further enhancing the imaging effect.

[0044] In some embodiments, the width of the isolation region 113 is within a second preset range along the direction from the mounting area 111 to the edge region 112. This second preset range is specifically determined based on factors such as the overall dimensions of the lens 100, the mounting requirements of the reflective film 20, and the processing needs of the edge region 112. In some examples, the second preset range refers to a numerical range of 0.5 mm to 1 mm, which depends on the mounting tolerance of the lens substrate 10 on the mold during the coating of the reflective film 20 onto the mounting area 111.

[0045] In some embodiments, please refer to Figure 4 and Figure 5 The second surface 12 is provided with a second texture, which at least partially covers the second surface 12. The second texture is used to absorb the light that shines on the second surface 12, thereby reducing the interference of light transmitted from the second surface 12, i.e. the back of the lens 100, on the imaging effect.

[0046] In some embodiments, the second texture completely covers the second surface 12 to further prevent light transmitted through the back of the lens 100 from interfering with the reflection effect of the reflective area of ​​the lens 100.

[0047] In some embodiments, the second texture is one or more fine structures such as serrated, wavy, or dot-matrix patterns. In some embodiments, the second texture is uniformly distributed on the second surface 12 to ensure light absorption effect. In some embodiments, the second texture is periodically distributed on the second surface 12, which is beneficial to the consistency and stability of the second texture.

[0048] In some embodiments, please refer to Figure 3 and Figure 4The lens 100 also includes a first mounting component 30 and a second mounting component 40, which are respectively disposed on both sides of the lens substrate 10. The first mounting component 30 and the second mounting component 40 are used to connect with external devices to install and fix the lens 100 to the external devices.

[0049] In some embodiments, the first mounting member 30 is provided with a third texture, which at least partially covers the first mounting member 30. The third texture is used to reduce the impact of reflected light or internally transmitted light generated on the surface of the mounting member on the reflection effect of the reflective area of ​​the lens 100.

[0050] In some embodiments, the second mounting member 40 is provided with a third texture, which at least partially covers the second mounting member 40. Optionally, the texture on the second mounting member 40 may be the same as or different from the texture on the first mounting member 30.

[0051] In some embodiments, the third texture completely covers the first mounting member 30 and / or the second mounting member 40 to further reduce the interference of the mounting members on the reflective effect of the lens 100.

[0052] In some embodiments, the third texture is one or more fine structures such as serrated, wavy, or dot-matrix patterns. In some embodiments, the third texture is uniformly distributed to ensure diffuse reflection. In some embodiments, the third texture is periodically distributed, which is beneficial to the consistency and stability of the third texture.

[0053] In some embodiments, the first, second, and third textures are all identical, which simplifies the manufacturing process and ensures the consistency of optical performance between the lens substrate 10 and the mounting components, thus improving overall image quality and reducing stray light interference. In other embodiments, at least two of the first, second, and third textures are different to accommodate the functional requirements and light reception conditions of different parts of the lens 100. In some examples, since the first surface 11 faces more direct sunlight, while the second surface 12 and the mounting components mainly face interference from internal transmitted light, the texture density of the first texture is greater than that of the second and third textures to enhance the diffuse reflection effect of the first surface 11 and reduce production costs. Texture density refers to the number of textures per unit area or the total length of the textures.

[0054] It is understood that the structure of the lens 100 is not limited to the above-mentioned limitations, and may also be other structures. For example, in some embodiments, the lens 100 further includes an adjustment mechanism connected to the first mounting component 30 and the second mounting component 40. The adjustment mechanism is used to adjust the angle and position of the first mounting component 30 and the second mounting component 40, thereby adjusting the angle and / or position of the lens 100 to adapt to the different vision needs of different drivers or the differences in vehicle installation environment.

[0055] In this embodiment, by providing a first texture in the edge region 112 of the lens substrate 10, external sunlight illuminating the edge region 112 is effectively absorbed, preventing the formation of bright spots in the edge region 112 and thus significantly reducing stray light generation in the lens 100. By providing an isolation region 113 between the edge region 112 and the mounting region 111, stray light problems caused by deviations in the coating process of the reflective film 20 are effectively reduced, enhancing the clarity and stability of the image.

[0056] Secondly, this application also provides an embodiment of a head-up display device, which includes the lens 100 described above. The structure and function of the lens 100 can be found in the above embodiments, and will not be repeated here.

[0057] Thirdly, this application also provides an embodiment of a vehicle. In some embodiments, the vehicle includes the aforementioned lens 100. The structure and function of the lens 100 can be found in the aforementioned embodiments and will not be repeated here. In other embodiments, the vehicle includes the aforementioned head-up display device. The structure and function of the head-up display device can be found in the aforementioned embodiments and will not be repeated here.

[0058] Fourthly, this application also provides an embodiment of a manufacturing method for lens 100; please refer to [link to embodiment]. Figure 6 The manufacturing method includes the following steps:

[0059] Step S10: Provide a substrate having a first surface.

[0060] Specifically, the substrate can be made of glass or plastic materials such as PC (polycarbonate) or COC (cyclic olefin copolymer). In some embodiments, please refer to [further details omitted]. Figure 7 The substrate is made of PC material using injection molding technology. The preparation process includes the following steps:

[0061] Step S11: Pre-treat the PC material.

[0062] The PC material is dried to a moisture content of less than or equal to 0.02% to reduce the risk of abnormal appearances such as bubbles and silver streaks during injection molding, as well as a decrease in the mechanical strength of the molded substrate. In some examples, the PC material is dried using a hot air dryer at 120°C for 3 to 5 hours.

[0063] Step S12: Provide an injection mold.

[0064] The specific shape of the injection mold matches the preset shape of the substrate.

[0065] Step S13: Injection molding.

[0066] Pre-treated PC material is added to the hopper of the injection molding machine, and parameters such as injection temperature, pressure, speed, and cooling time are set. When the injection molding machine starts working, the PC material is first heated to a molten state, with a temperature between 240℃ and 320℃. The specific temperature depends on factors such as the properties of the PC material, the shape, size, and performance requirements of the pre-molded substrate, and the structure of the injection mold. Next, it is injected under high pressure into the mold cavity through the mold's runner system. The injection mold temperature is between 70℃ and 120℃ to reduce the risk of PC material decomposition due to excessively high mold temperatures, which could lead to a darker color of the molded substrate, surface defects such as silver streaks, dark lines, black spots, and bubbles, and a decline in physical and mechanical properties. The specific mold temperature depends on factors such as the properties of the PC material, the shape, size, and performance requirements of the pre-molded substrate, and the structure of the injection mold. Then, within the mold cavity, the molten PC material fills the entire cavity and rapidly solidifies under the action of the mold's cooling system, forming a substrate with the pre-set shape.

[0067] Step S20: Divide the first surface into an edge area and an installation area, with the edge area surrounding the installation area.

[0068] Specifically, please refer to Figure 8, which shows a sub-process of step S20 in the figure. The steps of dividing the first surface into an edge area and a mounting area, with the edge area surrounding the mounting area, include:

[0069] Step S21: Divide the first surface into an edge area, a mounting area, and an isolation area. The isolation area is located between the edge area and the mounting area. The edge area surrounds the isolation area, and the isolation area surrounds the mounting area.

[0070] Along the direction from the mounting area to the edge area, the width of the edge area is within a first preset range, and the width of the isolation area is within a second preset range. In some embodiments, the first preset range refers to a numerical range of 0.5 mm to 1 mm. The second preset range refers to a numerical range of 0.5 mm to 1 mm, which depends on the mounting tolerance of the lens substrate on the mold during the process of applying the reflective film to the mounting area.

[0071] Step S30: Texture the edge area to form a first texture in the edge area, and obtain the lens substrate.

[0072] Specifically, the edge area is textured using methods such as laser engraving and chemical etching to form a first texture. The first texture is one or more fine structures such as serrated, wavy, or dot-matrix patterns. The first texture at least partially covers the edge area and is evenly and / or periodically distributed. In some embodiments, please refer to [further details omitted]. Figure 9 The figure shows a sub-process of step S30 in the figure, which is a step of texture processing of the edge area, and further includes:

[0073] Step S31: Provide a protective film and apply it to the substrate except for the edge area.

[0074] Protective films are used to protect non-edge areas of the substrate during texture processing, preventing damage or contamination to these areas. Protective films can be made of materials with high temperature resistance, high adhesion, and easy peelability, such as PVA (polyvinyl alcohol) films or polyester films.

[0075] Step S32: Provide a masking material and set the masking material on the edge area to mask the area on the edge area except for the texture pattern.

[0076] The texture pattern is a preset pattern of the first texture. The masking material is used to protect the portion of the edge area outside the preset pattern of the first texture from damage or contamination. The masking material can be a masking tape, masking film, or sprayed substance that is resistant to chemical corrosion or high temperature.

[0077] Step S33: Provide an etching solution and immerse the substrate in the etching solution to etch the area of ​​the texture pattern to form a first texture.

[0078] The etching solution can be, for example, hydrofluoric acid, nitric acid, or a mixed solution, depending on the substrate material and the desired etching effect. During the etching process, the textured areas not covered by the masking material react with the etching solution, thereby etching out the predetermined first texture shape. Parameters such as etching time, temperature, and solution concentration are determined according to actual requirements.

[0079] Step S34: Remove the protective film and masking material from the substrate.

[0080] The protective film and masking material are removed by means of sandblasting, mechanical peeling or chemical solvent cleaning to obtain a lens substrate with a first texture in the edge area.

[0081] Step S40: Provide a reflective film material and deposit the reflective film material onto the mounting area to form a reflective film in the mounting area.

[0082] The lens substrate is placed in a vacuum environment, and the reflective film material is heated to its evaporation temperature, causing the reflective film material to be uniformly deposited in gaseous form on the surface of the mounting area, thereby forming a reflective film. The reflective film material can be aluminum, silver, or other optical materials with high reflectivity and low absorption characteristics, and the specific choice depends on the required reflective properties and application scenario.

[0083] In some embodiments, please refer to Figure 6 ,exist Figure 6 Before step S30 in the manufacturing method shown, that is, before the step of texturing the edge area, the method further includes:

[0084] Step S50: Chamfer the edge area.

[0085] Specifically, the edges of the substrate are chamfered and polished using a rounding machine or a digital lathe to form an edge area with a curved surface.

[0086] In some embodiments, please refer to Figure 6 The substrate further includes a second surface, which is disposed opposite to the first surface, and the manufacturing method further includes:

[0087] Step S60: Texture the second surface to form a second texture on the second surface, the second texture at least partially covering the second surface.

[0088] The second surface is textured using methods such as laser engraving and chemical etching to form a second texture. The second texture is one or more fine structures, such as serrated, wavy, or dot-matrix patterns, and is evenly and / or periodically distributed. It is understood that the second texture and the first texture may be the same or different. The steps of texturing the second surface and texturing the edge area can be performed simultaneously or separately, depending on production requirements.

[0089] In some embodiments, please refer to Figure 10 The manufacturing methods for lenses also include:

[0090] Step S70: Provide the first mounting component and the second mounting component.

[0091] The first and second mounting components can be made of metal, plastic, or other materials, depending on the connection requirements of the lens substrate and compatibility with external devices.

[0092] Step S80: Texture the first mounting component and / or the second mounting component to form a third texture, the third texture at least partially covering the first mounting component and / or the second mounting component.

[0093] A third texture is formed by texturing the mounting component using methods such as laser engraving and chemical etching. The third texture is one or more fine structures such as serrated, wavy, or dot-matrix patterns, and it is evenly and / or periodically distributed. It is understood that the first, second, and third textures can be the same, or at least two of the first, second, and third textures can be different. The steps of texturing the mounting component, texturing the second surface, and texturing the edge area can be performed simultaneously or separately.

[0094] Step S90: Fix the first mounting component and the second mounting component to both sides of the lens substrate, respectively.

[0095] The first and second mounting components are installed and fixed to both sides of the lens substrate by means of adhesive bonding or screw fixing to obtain a lens. The first and second mounting components are used to connect to external devices, thereby mounting the lens onto the external devices.

[0096] In this embodiment, the lens manufacturing method described above introduces a first texture into the edge area of ​​the lens substrate, effectively absorbing external sunlight that illuminates the edge area and preventing the formation of bright spots in the edge area, thereby effectively reducing the generation of stray light from the lens. Simultaneously, by setting an isolation area and depositing a reflective film on the mounting area, stray light problems caused by deviations during the reflective film deposition process are effectively reduced, enhancing the clarity and stability of the image.
