Description

Technical Field

[0001] Embodiments of the present invention relate to the field of optical technologies, and in particular, to a lens, a head-up display device, a vehicle, and a manufacturing method of the lens. Background Art

[0002] A head-up display device (HUD) is an auxiliary driving device. Centered on the driver, through the principle of optical reflection, important information such as speed and navigation is projected onto the windshield in front of the driver, enabling the driver to avoid looking down at the dashboard during driving, thus improving driving safety and convenience. Among them, the HUD lens is an important component of the head-up display device, which is used to reflect and project the image light of the image generation unit onto the windshield.

[0003] In practical applications, the HUD lens is easily interfered by the problem of sunlight backflow, generating stray light. Under strong sunlight conditions, external sunlight irradiates the edge of the HUD lens through the windshield. Due to process problems, in the actual injection molding process, the edge of the lens often cannot reach the ideal design state, forming small rounded corners of about 0.2 mm. After being irradiated by sunlight, high-brightness spots will be formed, which are reflected by the windshield and enter the eye box range, generating stray light and causing defects in the imaging effect. Currently, mainly by adding additional shielding components, such as sun visors, light shields, or side shielding strips, etc., to reduce the generation of stray light.

[0004] In the process of implementing the embodiments of the present invention, the inventors found that: the additional shielding components not only increase the complexity and cost of the head-up display system, but also cause a certain degree of obstruction to the driving vision, affecting the driver's comprehensive observation of the road conditions ahead.

[0034] The present invention will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made. These all belong to the protection scope of the present invention.

[0035] For ease of understanding of this application, the following provides a more detailed description of this application in conjunction with 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 those skilled in the technical field to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not used to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0036] It should be noted that if there is no conflict, the various features in the embodiments of the present invention can be combined with each other, and all are within the protection scope of this application. In addition, although functional module division is carried out in the device schematic diagram, in some cases, it can be different from the module division in the device. In addition, the terms "first", "second", etc. used herein do not limit the data and execution order, but only distinguish the same items or similar items with basically the same function and role.

[0037] In the head - up display device, please refer to Figure 1 and Figure 2, the image light generated by the image generation unit 1 is reflected by the lens 2 and the lens 3 and then projected onto the windshield 4. The windshield 4 reflects the light to the eye box area 5, enabling the driver to observe clear image information. In the event of sunlight backflow, on the one hand, during the design process, the edges of the lens are often sharp corners. In the actual injection molding process, it is often impossible to achieve the ideal design state, and small round corners of about 0.2 mm will be formed. These small round corners will form bright spot stray light when sunlight backflows. On the other hand, referring to Figure 2 , due to the problem that the reflective film is coated on the non-imaging area during the lens manufacturing process, especially on the edge of the lens, when sunlight backflows, the edge will reflect sunlight, thus forming stray light. Please refer to Figure 1 , sunlight will pass through the windshield 4 and shine on the edge of the lens 3. The edge of the lens 3 reflects or converges and reflects the sunlight, causing the light to be reflected back through the windshield 4 and enter the eye box area 5, affecting the imaging effect. Please refer to Figure 2 , sunlight passes through the windshield 4 and 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 overlap of the image light and the sunlight, reducing the clarity and visibility of the image.

[0038] To improve the above technical problems, the embodiments of the present application provide a lens 100, a head-up display device, a vehicle, and a manufacturing method of the lens 100, reducing the risk of stray light appearing at the edge of the lens 100, thereby improving the imaging quality.

[0039] In a first aspect, the embodiments of the present 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.

[0040] 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 that are oppositely arranged. The first surface 11 is provided with an installation area 111 and an edge area 112. The installation area 111 is used to install the reflective film 20, and the edge area 112 is arranged around the installation area 111. The edge area 112 is provided with a first texture. The first texture at least partially covers the edge area 112, and the first texture is used to absorb the light irradiating on the edge area 112, reducing the risk of stray light formed due to the reflection of the edge area 112.

[0041] In some embodiments, the first texture completely covers the edge area 112, so that when light with different incident angles irradiates on the edge area 112, the light can be effectively diffusely reflected, further reducing the generation of stray light.

[0042] In some embodiments, the first texture is one or more of fine structures such as serrated, wavy, or dot matrix patterns. In some embodiments, the first texture is uniformly distributed in the edge region 112, which not only ensures the light absorption effect 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.

[0043] In some embodiments, referring to Figure 3 and Figure 5 , the reflective film 20 is disposed in the mounting area 111 to form a reflective area of the lens 100, and the reflective area is used to reflect preset incident light to a preset target area. The reflective film 20 is made of an optical material having a high reflectivity and low absorption characteristics, such as one or more of metal films and dielectric films such as aluminum films, and is specifically determined according to actual application requirements. In some examples, in the head-up display application scenario, the reflective area formed by the reflective film 20 and the mounting area 111 is used to reflect the image light of the image generation unit and project it onto the windshield.

[0044] In some embodiments, the edge region 112 is an arc surface, and one end of the arc surface away from the mounting area 111 is connected to the second surface 12, so that the transition between the edge region 112 and the second surface 12 is smoother, reducing the risk of light focusing caused by sharp edges. At the same time, the arc surface can provide a wider reflection angle, so that the light irradiated to the edge region 112 can be more fully absorbed by the first texture.

[0045] In some embodiments, along the direction from the first surface 11 to the second surface 12, the width of the projected area of the edge region 112 is within a first preset range. In some examples, the first preset range is from 0.2 mm to 0.5 mm. In some examples, the first preset range is from 0.5 mm to 1 mm. Of course, the first preset range can also be greater than 1 mm, which is specifically selected according to the actual situation and is not limited here.

[0046] In some embodiments, referring to Figure 3 , the first surface 11 is further provided with an isolation area 113, and the isolation area 113 is disposed between the mounting area 111 and the edge region 112. The isolation area 113 surrounds the mounting area 111, and the edge region 112 surrounds the isolation area 113. The isolation area 113 isolates the edge region 112 and the mounting area 111 for mounting the reflective film 20 to prevent the edge of the reflective film 20 from directly contacting the edge region 112 during processing or use, thereby preventing the generation of stray light caused by the reflective film 20 entering the edge region 112 and further enhancing the imaging effect.

[0047] In some embodiments, along the direction from the installation area 111 to the edge area 112, the width of the isolation area 113 is within a second preset range, and the second preset range is specifically determined according to factors such as the overall size of the lens 100, the installation requirements of the reflective film 20, and the needs of processing the edge area 112. In some examples, the second preset range refers to a numerical range of 0.5 mm to 1 mm, and this numerical range depends on the installation tolerance of the lens substrate 10 when installed in the mold during the process of coating the reflective film 20 on the installation area 111.

[0048] In some embodiments, refer to Figure 4 and Figure 5 , the second surface 12 is provided with second texture lines, and the second texture lines at least partially cover the second surface 12. The second texture lines are used to absorb the light incident on the second surface 12, thereby reducing the interference of the light transmitted through the second surface 12, that is, the back surface of the lens 100, on the imaging effect.

[0049] In some embodiments, the second texture lines completely cover the second surface 12 to further avoid the interference of the light transmitted through the back surface of the lens 100 on the reflection effect of the reflection area of the lens 100.

[0050] In some embodiments, the second texture lines are one or more of microstructures such as serrated, wavy, or dot matrix patterns. In some embodiments, the second texture lines are evenly distributed on the second surface 12 to ensure the light absorption effect. In some embodiments, the second texture lines are periodically distributed on the second surface 12, which is beneficial to the consistency and stability of the second texture lines.

[0051] In some embodiments, refer to Figure 3 and Figure 4 , the lens 100 further includes a first mounting member 30 and a second mounting member 40. The first mounting member 30 and the second mounting member 40 are respectively disposed on both sides of the lens substrate 10. The first mounting member 30 and the second mounting member 40 are used to connect to an external device to mount and fix the lens 100 to the external device.

[0052] In some embodiments, the first mounting member 30 is provided with third texture lines, and the third texture lines at least partially cover the first mounting member 30. The third texture lines are used to reduce the influence of the reflected light generated on the surface of the mounting member or the internally transmitted light on the reflection effect of the reflection area of the lens 100.

[0053] In some embodiments, the second mounting member 40 is provided with third texture lines, and the third texture lines at least partially cover the second mounting member 40. Optionally, the texture lines on the second mounting member 40 are the same as or different from the texture lines on the first mounting member 30.

[0054] 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 member on the reflection effect of the lens 100.

[0055] In some embodiments, the third texture is one or more of fine structures such as a serrated shape, a wavy shape, or a dot matrix pattern. In some embodiments, the third texture is evenly distributed to ensure a diffuse reflection effect. In some embodiments, the third texture is periodically distributed, which is beneficial to the consistency and stability of the third texture.

[0056] In some embodiments, the first texture, the second texture, and the third texture are all the same texture, which is beneficial to simplifying the manufacturing process and ensuring the consistency of the optical properties of the lens substrate 10 and the mounting member, helping to improve the overall imaging quality and reduce stray light interference. In some other embodiments, at least two of the first texture, the second texture, and the third texture are different to adapt to the functional requirements and light-receiving conditions of different parts of the different lenses 100. In some examples, since the first surface 11 faces more direct sunlight irradiation and the second surface 12 and the mounting member mainly face the interference of internal transmitted light, the texture density of the first texture is greater than the texture density of the second texture and the texture density of the third texture to enhance the diffuse reflection effect of the first surface 11 and reduce the production cost. The texture density refers to the number of textures or the total length of the textures per unit area.

[0057] It can be understood that the structure of the lens 100 is not limited to the above, and it can also be other structures. For example, in some embodiments, the lens 100 further includes an adjustment mechanism, and the adjustment mechanism is connected to the first mounting member 30 and the second mounting member 40. The adjustment mechanism is used to adjust the angles and positions of the first mounting member 30 and the second mounting member 40, so as to adjust the angle and / or position of the lens 100 to adapt to the line-of-sight requirements of different drivers or the differences in the vehicle installation environment.

[0058] In the embodiments of the present application, by providing the first texture in the edge area 112 of the lens substrate 10, the external sunlight irradiating the edge area 112 is effectively absorbed, avoiding the formation of high-brightness spots by the sunlight in the edge area 112, thereby significantly reducing the generation of stray light of the lens 100. By providing the isolation area 113 between the edge area 112 and the mounting area 111, the problem of stray light caused by the deviation in the coating process of the reflective film 20 is effectively reduced, enhancing the clarity and stability of imaging.

[0059] In a second aspect, the present application also provides an embodiment of a head-up display device. The head-up display device includes the above-mentioned lens 100. For the structure and function of the lens 100, reference can be made to the above embodiments, and details are not described herein again.

[0060] In a third aspect, the present application also provides an embodiment of a vehicle. In some embodiments, the vehicle includes the above-mentioned lens 100. For the structure and function of the lens 100, reference may be made to the above embodiments, and details will not be repeated here. In other embodiments, the vehicle includes the above-mentioned head-up display device. For the structure and function of the head-up display device, reference may be made to the above embodiments, and details will not be repeated here.

[0061] In a fourth aspect, the present application also provides an embodiment of a manufacturing method of the lens 100. Please refer to Figure 6 , and the manufacturing method includes the following steps:

[0062] Step S10: Provide a substrate, and the substrate is provided with a first surface.

[0063] Specifically, the substrate can be made of a glass material or a plastic material such as PC (polycarbonate), COC (cycloolefin copolymer), etc. In some embodiments, please refer to Figure 7 , the substrate is made of PC material by an injection molding technique, and the preparation process includes the following steps:

[0064] Step S11: Pretreat the PC material.

[0065] The PC material is dried so that the moisture content of the PC material is less than or equal to 0.02% to reduce the risk of abnormal appearances such as bubbles and silver streaks during the injection molding process and the reduction of the mechanical strength of the formed substrate. In some examples, drying the PC material includes drying the PC material at a temperature of 120°C for 3 to 5 hours by a hot air dryer.

[0066] Step S12: Provide an injection mold.

[0067] The specific shape of the injection mold matches the preset shape of the substrate.

[0068] Step S13: Injection molding.

[0069] The pre-treated PC material is added into 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 to work, the PC material is first heated to a molten state, and the temperature of the molten PC material is between 240°C and 320°C. The specific temperature depends on factors such as the properties of the PC material, the shape, size, and performance requirements of the preset molded substrate, and the structure of the injection mold. Then, it is injected into the mold cavity under high pressure through the runner system of the injection mold. The temperature of the injection mold is between 70°C and 120°C to reduce the decomposition of the PC material caused by too high mold temperature, thereby preventing problems such as the color of the molded substrate becoming darker, the appearance of silver streaks, dark stripes, black spots, bubbles, etc. on the surface, and the decline of 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 preset molded substrate, and the structure of the injection mold. Then, in the mold cavity, the molten PC material fills the entire cavity and quickly solidifies and forms under the action of the cooling system of the mold to form a substrate with a preset shape.

[0070] Step S20: Divide the first surface into an edge area and an installation area, and the edge area is arranged around the installation area.

[0071] Specifically, please refer to FIG. 8 together. The figure is a sub-process of step S20 in the figure. The step of dividing the first surface into an edge area and an installation area, with the edge area arranged around the installation area, includes:

[0072] Step S21: Divide the first surface into an edge area, an installation area, and an isolation area. The isolation area is located between the edge area and the installation area. The edge area is arranged around the isolation area, and the isolation area is arranged around the installation area.

[0073] Along the direction from the installation 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, and this numerical range depends on the installation tolerance of the lens substrate in the mold during the process of coating the reflective film on the installation area.

[0074] Step S30: Perform texture treatment on the edge area to form a first texture on the edge area and obtain the lens substrate.

[0075] Specifically, the edge area is texture-treated by means such as laser engraving and chemical etching to form the first texture. The first texture is one or more of fine structures such as serrated, wavy, or dot matrix patterns. The first texture at least partially covers the edge area, and the first texture is evenly distributed and / or periodically distributed. In some embodiments, please refer to FIG. Figure 9 , the figure is a sub-process of step S30 in the figure. The step of performing texture treatment on the edge area further includes:

[0076] Step S31: Provide a protective film and affix the protective film to the area of the substrate other than the edge area.

[0077] The protective film is used to protect the area of the non-edge region of the substrate during the texture processing, preventing the area of the non-edge region from being damaged or contaminated. The protective film can be a material with high heat resistance, high adhesion, and easy peel-off properties, such as a PVA (polyvinyl alcohol) film or a polyester film, etc.

[0078] Step S32: Provide a masking material and dispose the masking material in the edge area to mask the area on the edge area other than the texture pattern.

[0079] The texture pattern is a preset pattern of the first texture. The masking material is used to protect the part of the edge area other than the preset pattern of the first texture from being damaged or contaminated. The masking material can be a masking tape, a masking film, or a spraying substance that is resistant to chemical corrosion or high temperature, etc.

[0080] Step S33: Provide an etching solution and immerse the substrate in the etching solution to etch the area of the texture pattern to form the first texture.

[0081] The etching solution can be, for example, hydrofluoric acid, nitric acid, or a mixed solution, etc. The specific selection depends on the material of the substrate and the required etching effect. During the etching process, the area of the texture pattern not covered by the masking material reacts with the etching solution, and thus the preset shape of the first texture is etched out. Parameters such as the etching time, temperature, and solution concentration are determined according to actual requirements.

[0082] Step S34: Remove the protective film and the masking material from the substrate.

[0083] Remove the protective film and the masking material by means such as sandblasting, mechanical peeling, or chemical solvent cleaning, etc., to obtain a lens substrate with the first texture in the edge area.

[0084] Step S40: Provide a reflective film material and evaporate the reflective film material onto the mounting area to form a reflective film on the mounting area.

[0085] Place the lens substrate in a vacuum environment, heat the reflective film material to its evaporation temperature, and make the reflective film material uniformly deposit on the surface of the mounting area in a gaseous form, thereby forming a reflective film. The reflective film material can be aluminum, silver, or other optical materials with high reflectivity and low absorption characteristics. The specific selection depends on the required reflective characteristics and application scenarios.

[0086] In some embodiments, refer to Figure 6 , in Figure 6 the manufacturing method shown, before step S30, that is, before the step of performing texture processing on the edge area, the method further includes:

[0087] Step S50: Chamfer the edge area.

[0088] Specifically, a rounding machine or a digital lathe is used to chamfer and grind the edges of the substrate to form an arc-shaped edge area.

[0089] In some embodiments, referring to Figure 6 , the substrate further includes a second surface, which is disposed opposite to the first surface, and the manufacturing method further includes:

[0090] Step S60: Texture the second surface to form a second texture on the second surface, and the second texture at least partially covers the second surface.

[0091] The second surface is textured by means such as laser engraving and chemical etching to form the second texture. The second texture is one or more of fine structures such as serrated, wavy or dot matrix patterns, and the second texture is evenly distributed and / or periodically distributed. It can be understood that the textures of the second texture and the first texture may be the same or different, and the step of texturing the second surface and the step of texturing the edge area may be carried out simultaneously or separately, depending on production requirements, etc.

[0092] In some embodiments, referring to Figure 10 , the manufacturing method of the lens further includes:

[0093] Step S70: Provide a first mounting component and a second mounting component.

[0094] The first mounting component and the second mounting component can be made of metal, plastic or other materials, specifically depending on the connection requirements of the lens substrate and the compatibility with external devices.

[0095] Step S80: Texture the first mounting component and / or the second mounting component to form a third texture, and the third texture at least partially covers the first mounting component and / or the second mounting component.

[0096] The mounting component is textured by means such as laser engraving and chemical etching to form the third texture. The third texture is one or more of fine structures such as serrated, wavy or dot matrix patterns, and the third texture is evenly distributed and / or periodically distributed. It can be understood that the first texture, the second texture and the third texture may be the same texture, or at least two of the first texture, the second texture and the third texture have different textures. The step of texturing the mounting component, the step of texturing the second surface, and the step of texturing the edge area may be carried out simultaneously or separately.

[0097] Step S90: Fix the first mounting component and the second mounting component on both sides of the lens substrate respectively.

[0098] The first mounting component and the second mounting component are mounted and fixed on both sides of the lens substrate by means of paste fixation or screw fixation, etc., so as to obtain a lens. The first mounting component and the second mounting component are used to connect with an external device, so as to mount the lens on the external device.

[0099] In the embodiment of the present application, through the above-mentioned manufacturing method of the lens, a first texture is introduced into the edge area of the lens substrate, effectively absorbing the external sunlight irradiated to the edge area, avoiding the formation of high-brightness highlights in the edge area, and thus effectively reducing the generation of lens stray light. At the same time, by setting an isolation area and evaporating a reflective film on the mounting area, the problem of stray light caused by the deviation in the process of coating the reflective film is effectively reduced, and the clarity and stability of imaging are enhanced.

[0100] It should be noted that the description and drawings of the present invention give preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification.
