Description

[0002] As intelligent products play an increasingly important role in the automotive field, AR-HUD has become an indispensable part of car driving. The head-up display is used to project information on the windshield. Based on this function, AR-HUD can also mark road conditions, weather, temperature and other information, greatly improving driving efficiency and riding comfort. In order to achieve such an imaging effect, different reflectors need to work together.

[0003] The traditional head-up display's light reflection component has only one plane reflector. Under normal circumstances, the image is displayed normally. However, under special light, there will be a white flare in the image, which may hinder the driver's field of vision. The imaging unit needs to be adjusted to reduce the light impact and weaken the flare effect to achieve an ideal view. At the same time, because the traditional plane reflector is installed on the lower shell, considering the mold and molding, the light reflection space is exposed to the outside, forming additional stray light, which in turn affects the imaging effect.

[0004] Therefore, how to improve the imaging effect of the head-up display is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0055] The core of the utility model is to provide a light reflection component, a head-up display and a car, so as to improve the imaging effect of the head-up display.

[0056] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation methods.

[0057] Please refer to Figures 1 to 22 .

[0058] In a specific embodiment, the light reflection assembly provided by the specific embodiment of the utility model includes a first plane reflector 20, a second plane reflector 30, a diffusion film 10 and a light shielding shell 40, the second plane reflector 30 is used to receive the reflected light of the first plane reflector 20, the area of ​​the second plane reflector 30 is larger than the area of ​​the first plane reflector 20, preferably, the light from the first plane reflector 20 is projected to the second plane reflector 30, and the projection of the first plane reflector 20 is within the projection range of the second plane reflector 30, at this time, the second plane reflector 30 can fully receive the light of the first plane reflector 20, and disperse the light during reflection to prevent it from being reflected back to the first plane reflector 20 again to form white spot flare. Specifically, the specific area and shape of the first plane reflector 20 and the second plane reflector 30 are determined according to actual needs, and this application does not make specific restrictions.

[0059] The light reflected by the second plane reflector 30 is emitted through the diffusion film 10, and the light shielding shell 40 is provided with a light incident port for irradiating the light on the first plane. The first plane reflector 20, the second plane reflector 30 and the diffusion film 10 are all installed on the light shielding shell 40, and the first plane reflector 20, the second plane reflector 30, the diffusion film 10 and the light shielding shell 40 are enclosed to form a light shielding space. Specifically, the light shielding space enclosed by the first plane reflector 20, the second plane reflector 30, the diffusion film 10 and the light shielding shell 40 is only injected through the light incident port, and other positions are closed structures. When no light enters, the enclosed space is a light shielding space similar to a black room.

[0060] During specific assembly, Figure 1 As shown, the diffusion film 10 is flatly attached to the front of the light shielding shell 40. Fig.18 As shown, the light shielding shell 40 is provided with a first mounting hole 4010 for mounting the diffusion film 10. Fig.19 As shown, the light shielding shell 40 is provided with a second mounting hole 4011 for mounting the first plane reflector 20, and the light shielding shell 40 is provided with a third mounting hole 409 for mounting the first plane reflector 20. In order to limit the diffusion film 10, preferably, the light shielding shell 40 is provided with a limiting groove, and the diffusion film 10 is provided with a limiting protrusion adapted to the limiting groove, specifically, the limiting protrusion is a 3mm wide and 1.2mm thick protrusion.

[0061] When the light reflection component is used, the image light beam is emitted through the first plane reflection mirror 20 , the second plane reflection mirror 30 and the diffusion film 10 in sequence.

[0062] It can be seen from the above description that in the light reflection assembly provided by the present application, by setting the light shielding shell 40, the first plane reflector 20, the second plane reflector 30, the diffusion film 10 and the light shielding shell 40 enclose a light shielding space, which effectively avoids the influence of stray light. After the light beam is reflected by the first plane reflector 20, it is reflected again by the second plane reflector 30, which further reduces the influence of stray light, thereby eliminating flare and improving the imaging effect of the head-up display.

[0063] like Fig.16 As shown, in a specific embodiment, in order to improve the installation accuracy of the first plane reflector 20, preferably, the light shielding shell 40 is provided with a first positioning column 402, and the first plane reflector 20 is provided with a first positioning hole 603 adapted to the first positioning column 402. The first positioning hole 603 can be one or at least two, and the first positioning column 402 and the first positioning hole 603 correspond one to one. Preferably, the first positioning column 402 and the first positioning hole 603 are both cylindrical structures. There is an anti-collision groove 403 on the light shielding shell 40 at the position adapted to the corner of the first plane reflector 20. Specifically, there are three anti-collision grooves 403, which can prevent the edges and corners of the first plane reflector 20 from being damaged by collision when the first plane reflector 20 is placed.

[0064] like Fig.16 As shown, the light shielding shell 40 is provided with a first anti-error mounting portion 404 adapted to the first plane reflector 20. Specifically, the first anti-error mounting portion 404 is a 1mm×0.3mm bevel, and the first anti-error mounting portion 404 serves as an anti-error structure, wherein 1mm is the long side of the first anti-error mounting portion 404, and 0.3mm is the short side of the first anti-error mounting portion 404. Specifically, the first plane reflector 20 is also provided with an bevel of the same size at the same position, so that the first plane reflector 20 can only be placed at the preset position corresponding to the installation of the first plane reflector 20 on the light shielding shell 40 when the installation position is correct. The first anti-error mounting portion 404 at the first plane reflector 20 serves as an anti-error structure. If the first plane reflector 20 is flipped during installation, it cannot be placed in the light shielding shell 40.

[0065] The light-shielding shell 40 is provided with a first limiting piece 401 for clamping the first plane reflector 20. One first limiting piece 401 is installed on the left and right sides of the first plane reflector 20, and two first limiting pieces 401 are installed on the top and bottom. By adjusting the relative installation position of the first plane reflector 20 and the first limiting piece 401, the gap size of the first plane reflector 20 after assembly can be adjusted.

[0066] The light reflection assembly also includes a first bracket 60, through which the first plane reflector 20 is mounted on the light shielding shell 40, and a reflector mounting position 605 for mounting the first plane reflector 20 is provided on the first bracket 60. The first bracket 60 is detachably connected to the light shielding shell 40, and the first bracket 60 covers the light shielding surface of the first plane reflector 20, and the first bracket 60 is provided with a first elastic stopper 602 whose free end presses the light shielding surface of the first plane reflector 20. The first elastic stopper 602 can be a plastic sheet with a width of 6 mm and a length of 12 mm, and a thickness of 2 mm, which is distributed diagonally opposite to the first plane reflector 20, and its function is to press the first plane reflector 20 to prevent the first plane reflector 20 from moving.

[0067] Two first positioning posts 402 are provided on the light shielding shell 40, and a position adjustment hole 604 is provided on the first bracket 60. The two positioning posts are respectively installed in the first positioning hole 603 and the position adjustment hole 604, and the position adjustment hole 604 is a waist-shaped hole. Specifically, the two first positioning posts 402 are arranged at diagonal positions of the first plane reflector 20, and the diameter of the first positioning posts 402 is 2.6 mm and the height is 2 mm. The installation of the first bracket 60 and the light shielding shell 40 is limited by the two first positioning posts 402, and at the same time, the first bracket 60 is prevented from being deformed and causing the buckle to loosen.

[0068] The first positioning hole 603 is a cylindrical hole with a diameter of 3.1 mm and the position adjustment hole 604 is a strip hole with a length of 4.6 mm and a width of 3.1 mm.

[0069] To facilitate installation of the light reflecting assembly, the light shielding shell 40 is provided with three through holes arranged in a triangle with a diameter of 3.2 mm. The three through holes can be used to install the first bolt 70, the second bolt 80 and the third bolt 90 respectively to fix with other structures to realize installation of the light reflecting assembly.

[0070] The light shielding shell 40 is provided with a main positioning hole 405 with a diameter of 3.1 mm and a secondary positioning hole 406 with a diameter of 4.6 mm×3.1 mm. Specifically, the secondary positioning hole 406 can be a waist-shaped hole. When installing the light reflection component, one fastener is fixed to other structures through the main positioning hole 405, and the other fastener is fixed to other structures through the secondary positioning hole 406. Since the secondary positioning hole 406 is a bar-shaped hole, the positions of the fastener and the secondary positioning hole 406 can be adjusted, that is, the position of the light reflection component can be fine-tuned through the fastener.

[0071] The light shielding shell 40 is provided with a second anti-mistake mounting portion 408 adapted to the second plane reflector 30. Specifically, the second anti-mistake mounting portion 408 can be an oblique angle of 1 mm×0.3 mm. Specifically, the second plane reflector 30 is also provided with an oblique angle of the same size at the same position, so that the second plane reflector 30 can only be placed at the preset position corresponding to the installation of the second plane reflector 30 on the light shielding shell 40 when the installation position is correct. The second anti-mistake mounting portion 408 is provided at the position of the second plane reflector 30 as an anti-mistake structure. If the second plane reflector 30 is flipped at an angle during installation, it cannot be placed in the light shielding shell 40.

[0072] The light-shielding shell 40 is provided with a second stopper 407 that is clamped on the opposite sides of the second plane reflector 30. Specifically, the second stopper 407 can be a raised structure with a width of 2 mm, a height of 3 mm, and a thickness of 0.5 mm. Two second stoppers 407 are installed on the left and right sides of the second plane reflector 30, and the size change can be adjusted by this structure in the later stage. The light-shielding shell 40 is provided with a second anti-mistake mounting portion 408 that is adapted to the second plane reflector 30. The second anti-mistake mounting portion 408 is an oblique angle of 1 mm×0.3 mm. By setting the second anti-mistake mounting portion 408, if the angle of the second plane reflector 30 is flipped during installation, the second plane reflector 30 cannot be placed in the light-shielding shell 40.

[0073] like Figures 6 to 9 As shown, the light reflection assembly also includes a second bracket 50, and the second plane reflector 30 is installed on the light shielding shell 40 through the second bracket 50. The second bracket 50 is detachably connected to the light shielding shell 40. The second bracket 50 covers the light shielding surface of the second plane reflector 30, and the second bracket 50 is provided with a second elastic stopper 501 whose free end presses the light shielding surface of the second plane reflector 30. Specifically, the second elastic stopper 501 can be an elastic plastic part, and the second elastic stopper 501 can be one or at least two. The second elastic stopper 501 can be a plastic sheet with a width of 6mm and a length of 12mm, and a thickness of 2mm, which is distributed at the diagonal angle of the large plane mirror, and its function is to press the second plane reflector 30 to prevent the second plane reflector 30 from moving.

[0074] The light shielding shell 40 is provided with a second positioning column, and the second bracket 50 is provided with a second positioning hole 502 adapted to the second positioning column. In a specific embodiment, the diameter of the second positioning column is 2.6 mm and the height is 2 mm. Specifically, the sizes of the first positioning column 402 and the second positioning column are not limited to the above situation and can be adjusted according to actual needs. The second positioning hole 502 is used to limit the installation of the second bracket 50 and the light shielding shell 40, and at the same time, the deformation of the second bracket 50 is prevented to cause the light shielding shell 40 and the second bracket 50 to loosen the clamping position.

[0075] Specifically, the first bracket 60 is provided with a first buckle 601, and the second bracket 50 is provided with a second buckle 503, that is, the first buckle 601 and the second buckle 503 are snapped with the light shielding shell 40. Specifically, the first buckle 601 is that the first bracket 60 uses four female buckles as the first buckle 601 on the top and bottom, and the second bracket 50 uses two female buckles on the left and three female buckles on the right as the second buckle 503. The female buckles are all 10×7mm and 1.2mm thick. Male buckles are distributed at the corresponding positions of the light shielding shell 40. The male buckles are all 8×5mm, 1.2mm high, 1.5mm thick, and have uniform wall thickness. The male and female buckles are connected, and the side maintains a 1mm installation gap, and the front is zero sticking to ensure the installation strength.

[0076] The included angle between the first plane reflector 20 and the second plane reflector 30 is 67.05°-77.05°. Specifically, the included angle may be 69.05°-75.05°.

[0077] The included angle between the second plane reflector 30 and the diffusion film 10 is 46°-56°, and specifically, the included angle may be 48°-54°.

[0078] In a specific assembly method, first, the second plane reflector 30 is placed on the light shielding shell 40, and the second plane reflector 30 is surrounded by second stoppers 407. Then, the second bracket 50 is snap-connected with the light shielding shell 40, and the second plane reflector 30 is pressed by the second stoppers 407 on the second bracket 50. Specifically, the protective film of the second plane reflector 30 is torn off, and the second plane reflector 30 is placed flat in the second bracket 50. The second bracket 50 is snap-connected and clamped with the light shielding shell 40 by two snaps on the upper and lower sides. Next, the first plane reflector 20 is placed on the light shielding shell 40, and the first bracket 60 is snap-connected with the light shielding shell 40. The first plane reflector 20 is pressed by the second stoppers 407 on the first bracket 60. Specifically, the protective film of the first plane reflector 20 is torn off. Similarly, the first plane reflector 20 is placed flat in the light shielding shell 40, and the two snaps on the left side of the first bracket 60 and the three snaps on the right side are snap-connected and clamped with the light shielding shell 40. Finally, the diffusion film 10 is flatly attached to the light shielding shell 40 to form a plane mirror assembly product. After the installation is completed, the first plane reflector 20 is 72.06° flat with the second plane reflector 30, the inner space of the light shielding shell 40 forms a black room, and the diffusion film 10 and the second plane reflector 30 form an angle of 51°.

[0079] After the above assembly is completed, the protective film of the first plane reflector 20 and the second plane reflector 30 has been torn off, and the mirror surface is inside the light shielding shell 40, which effectively prevents the mirror surface from being dirty during the subsequent installation process. When disassembling, the buckles at the corresponding positions of the first plane reflector 20 and the second plane reflector 30 are directly opened to obtain the first plane reflector 20 and the second plane reflector 30, and they can be reused after post-processing, achieving the effect of convenient assembly and disassembly.

[0080] The reflection path of the light emitted by the imaging unit in the semi-finished plane mirror has a closed reflection space, which effectively avoids the influence of stray light, and controls the light reflection by placing the plane mirror and the diffusion film 10 at an angle to achieve the effect of eliminating flare, greatly improving the comfort and safety of the HUD (Head Up Display) imaging effect diagram for the driver, and solving the problem of white flare in HUD imaging that obstructs the driver's vision.
