Description

Technical Field

[0001] The utility model relates to an optical instrument, in particular to a head-up display and a vehicle. Background Art

[0002] With the development of automotive technology, head-up displays (HUDs) are increasingly being used in vehicles. They can project important information, such as speed and navigation instructions, directly in front of the driver's line of sight, improving driving safety. However, when using a HUD, ambient light can affect the photoelectric components within the HUD. Consequently, a shield is typically added to the HUD's housing. However, some ambient light is reflected from the photoelectric components onto the shield, and then refracted back onto the windshield. This can cause a "light spot" on the windshield, interfering with the driver's field of view and impacting the driving experience. Therefore, a HUD that can better mitigate the effects of ambient light interference is urgently needed. Utility Model Content

[0003] The purpose of the present utility model is to provide a head-up display and a vehicle to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] A head-up display according to an embodiment of the first aspect of the present invention is applied to a vehicle provided with a front windshield, comprising:

[0005] The housing has a light outlet on its top side that is connected to the interior;

[0006] An instrument panel cover is connected to the top side of the housing, and the instrument panel cover is formed with a hole above the light outlet;

[0007] an instrument panel connected to the rear top side of the instrument panel cover;

[0008] The image display component can emit light to the front windshield through the light outlet and the hole, and the ambient light passing through the front windshield and irradiating the image display component and then refracted is used as interference light. The interference light passes through the light outlet and the hole and is projected outside the instrument panel cover and the instrument panel.

[0009] This technical solution has at least the following beneficial effects: the image display component is used to display the image on the front windshield, the instrument panel cover is on the top side of the shell and is arranged around the light outlet of the shell, which can reduce the interference of foreign objects on the image display component in the shell, especially reduce the situation where the external ambient light enters the interior of the shell at the height of the light outlet of the shell, and the instrument panel is connected to the top side of the rear part of the instrument panel cover, that is, at the top side of the instrument panel cover close to the driver, and the instrument panel is used to further prevent the light inside the vehicle from entering the interior of the shell. When the external ambient light passes through the front windshield and shines on the image display component and is refracted outward, the interference light formed is not projected onto the instrument panel cover and the instrument panel, but is directly projected from above the instrument panel to the ceiling area of ​​the vehicle. In this way, it can reduce the light entering the interior of the shell and reduce the interference with the image display component, and can also effectively reduce the adverse effects of the external ambient light refracting from the image display component to the instrument panel cover and then refracting from the instrument panel cover to the front windshield to form light spots, thereby improving the driver's user experience and driving safety.

[0010] According to some embodiments of the present invention, the rear portion of the instrument panel and the instrument panel are positioned close to the interfering light. Positioning the instrument panel and instrument panel as close as possible to the interfering light not only effectively blocks ambient light from entering the housing, but also reduces the risk of interfering light being refracted through the instrument panel or instrument panel toward the front windshield.

[0011] According to some embodiments of the present invention, a first matte layer is provided on the inner side of the instrument panel cover. The first matte layer can effectively absorb ambient light refracted onto the instrument panel cover, thereby further preventing the ambient light refracted onto the instrument panel cover from being further refracted onto the front windshield.

[0012] According to some embodiments of the present invention, the first matte layer is a first flocking layer. The first flocking layer has good wear resistance and can effectively absorb light. The reflectivity of the flocking can reach less than 1%. In addition, light-colored flocking generally has a higher reflectivity than dark-colored flocking. Therefore, the first flocking layer can further reduce the refraction of ambient light and improve the driver's driving experience.

[0013] According to some embodiments of the present invention, a second matte layer is provided on a side of the instrument panel near the opening. Similarly, the second matte layer can effectively absorb ambient light refracted onto the instrument panel, thereby further preventing the ambient light refracted onto the instrument panel from being further refracted onto the front windshield.

[0014] According to some embodiments of the present invention, the second matte layer is a second flocking layer. Similarly, the second flocking layer has good wear resistance and can effectively absorb light. The second flocking layer can further reduce the refraction of ambient light and improve the driver's driving experience.

[0015] According to some embodiments of the present invention, the image display assembly includes a light emitting device, a first reflector, and a second reflector installed in the housing. The light emitting device is capable of emitting light toward the first reflector. The first reflector refracts the light emitted by the light emitting device toward the second reflector. The second reflector refracts the refracted light of the first reflector out of the light outlet and the hole and projects it onto the front windshield. The interfering light is the light refracted after being irradiated by the second reflector. The light emitting device is an electronic component that displays images, such as an LCD screen. The light emitting device refracts the light first through the first reflector to the second reflector, and then from the second reflector to the front windshield. After being refracted by the first and second reflectors, the image can be magnified and projected onto the front windshield for display.

[0016] According to some embodiments of the present invention, the second reflector is a cylindrical mirror. Using a cylindrical mirror as the second reflector helps reduce or eliminate the problem of stray light refracted onto the front windshield. The cylindrical mirror can better focus light and reduce the scattering angle of light, so that the external ambient light that enters the second reflector is concentrated, which helps reduce or eliminate the light reflected onto the instrument panel and instrument panel, thereby further reducing the impact of external ambient light on the driver's driving.

[0017] According to some embodiments of the present invention, the instrument panel extends around the opening, and a downwardly extending stop plate is connected to the front of the instrument panel. The stop plate abuts the instrument panel cover in front of the opening. During installation, the stop plate is inserted into the opening and abuts the instrument panel cover in front of the opening, quickly aligning the instrument panel cover and instrument panel, greatly improving overall assembly efficiency.

[0018] A vehicle according to an embodiment of the second aspect of the present utility model includes an instrument panel and the above-mentioned head-up display, wherein the housing is connected to the instrument panel.

[0019] This technical solution has at least the following beneficial effects: the above-mentioned head-up display is installed on the instrument panel, and the head-up display is used when driving the vehicle. Since the head-up display can reduce the external ambient light from entering the inner part of the shell and reduce the interference with the image display component, it can also effectively reduce the adverse effects such as the external ambient light being refracted from the image display component to the instrument panel cover and then refracted from the instrument panel cover to the front windshield to form light spots, thereby improving the driver's user experience and driving safety.

[0030] Reference Figure 1 According to an embodiment of the first aspect of the present invention, a head-up display is applied to a vehicle, wherein the vehicle is provided with a front windshield 500 and includes a housing 100, an instrument panel cover 200, an instrument panel 300, and an image display assembly, wherein:

[0031] The interior of the housing 100 is enclosed to form a space for installing external objects. A light outlet is provided on the top side of the housing 100, and the light outlet is communicated with the interior of the housing 100.

[0032] The instrument panel cover 200 is connected to the top side of the housing 100. The instrument panel cover 200 is formed with a hole above the light outlet. In actual use, the bottom side of the instrument panel cover 200 can be inserted into the light outlet, in which case the hole is directly formed along the light outlet. Alternatively, the instrument panel cover 200 can be directly connected and fixed to the top side of the housing 100, in which case the hole is formed above the light outlet.

[0033] The instrument panel 300 is connected to the rear top side of the instrument panel cover 200;

[0034] The image display component can emit light to the front windshield 500 through the light outlet and the hole, and the ambient light passing through the front windshield 500 and irradiating the image display component and then refracted is interference light. The interference light passes through the light outlet and the hole and is projected outside the instrument panel cover 200 and the instrument panel 300.

[0035] As can be seen from the above, the image display component is used to display the image on the front windshield 500. The instrument panel cover 200 is on the top side of the shell 100 and is arranged around the light outlet of the shell 100, which can reduce the interference of foreign objects on the image display component in the shell 100, especially reduce the situation where the external ambient light enters the shell 100 at the height of the light outlet. In addition, the instrument panel 300 is connected to the top side of the rear part of the instrument panel cover 200, that is, at the top side of the instrument panel cover 200 close to the driver. The instrument panel 300 is used to further prevent the light inside the car from entering the shell 100. When the external ambient light enters the shell 100, the instrument panel 300 is connected to the top side of the rear part of the instrument panel cover 200, that is, at the top side of the instrument panel cover 200 close to the driver. When the ambient light from the outside world passes through the front windshield 500 and illuminates the image display component and is refracted outward, the interference light formed is not projected onto the instrument panel cover 200 and the instrument panel 300, but is directly projected from above the instrument panel 300 to the ceiling area of ​​the vehicle. This can not only reduce the light entering the interior of the housing 100 and reduce the interference with the image display component, but also effectively reduce the adverse effects of the external ambient light being refracted from the image display component to the instrument panel cover 200 and then refracted from the instrument panel cover 200 to the front windshield 500 to form light spots, thereby improving the driver's user experience and driving safety.

[0036] The instrument panel 300 is installed on the top side of the instrument panel cover 200 and can be installed at a position relatively far back from the hole. At this time, after the interfering light passes through the hole formed by the instrument panel cover 200, since the installation position of the instrument panel 300 is far away from the hole, the interfering light is effectively avoided from being projected onto the instrument panel 300. Although this can effectively reduce the possibility of the interfering light passing through the instrument panel 300 and then refracting to the front windshield 500, it will weaken the effect of the instrument panel 300 in blocking the external ambient light from entering the outer shell 100. Therefore, in order to better take into account the light blocking function of the instrument panel 300, in this embodiment, the rear part of the instrument panel cover 200 and the instrument panel 300 tend to be close to the interfering light. During production, the instrument panel cover 200 and the instrument panel 300 are moved forward as far as possible so that interfering light from the interior of the vehicle tends to be projected onto the instrument panel cover 200 or the instrument panel 300. By positioning the instrument panel cover 200 and the instrument panel 300 as close as possible to the position of the interfering light, it is possible to ensure that the external ambient light is blocked from entering the interior of the housing 100, and to reduce the risk of interfering light being refracted through the instrument panel cover 200 or the instrument panel 300 toward the front windshield 500.

[0037] In actual applications, there are multiple beams of interference light formed by the external ambient light. Therefore, the interference light can form an interference area. When adjusting the positions of the instrument panel cover 200 and the instrument panel 300, the interference area formed by refraction can be confirmed through eye ellipses, glass inclination, glass curvature, etc. The instrument panel cover 200 and the instrument panel 300 are installed as close to the interference area as possible, so that the instrument panel cover 200 and the instrument panel 300 form a step to avoid the interference light.

[0038] When ambient light strikes the image display assembly, it is primarily reflected by the second reflector 430. Therefore, in the above embodiment, the focus is on projecting the light refracted by the second reflector 430 onto a location outside the instrument panel 300 and instrument cover 200. However, in actual applications, components within the image display assembly other than the second reflector 430 may also refract light, causing some ambient light to be refracted onto the instrument panel 200. Therefore, to further reduce interference caused by ambient light refracted by the image display assembly, in this embodiment, a first matte layer is provided on the inner side of the instrument panel 200. The first matte layer effectively absorbs ambient light refracted onto the instrument panel 200, thereby further preventing the ambient light refracted onto the instrument panel 200 from being further refracted onto the front windshield 500.

[0039] The first matte layer is mainly used to matte the light refracted onto the instrument panel cover 200. There are various structural forms, such as providing a frosted layer on the instrument panel cover 200, or providing leather grain or spray coating on the instrument panel cover 200. The reflectivity of leather grain is generally around 7%, and the reflectivity of spray coating is around 2% to 3%. In this embodiment, the first matte layer is a first flocking layer. The first flocking layer has good wear resistance and can effectively absorb light. The reflectivity of flocking can reach below 1%, and light-colored flocking generally has a higher reflectivity than dark-colored flocking. Therefore, the use of the first flocking layer can further reduce the refraction of ambient light and improve the driver's driving experience.

[0040] Similarly, components within the image display assembly other than the second reflector 430 also refract light, causing some ambient light to be refracted onto the instrument panel 300. Therefore, to further reduce interference caused by ambient light refracted by the image display assembly, in this embodiment, a second matte layer is provided on the side of the instrument panel 300 near the opening. This second matte layer effectively absorbs ambient light refracted onto the instrument panel 300, further preventing the ambient light refracted onto the instrument panel 300 from being further refracted onto the front windshield 500.

[0041] The second matte layer is primarily used to de-gloss the light refracted onto the instrument panel 300. This layer can be implemented in a variety of ways, such as by providing a frosted layer on the instrument panel 300, or by applying a leather grain or spray coating to the instrument panel 300. In this embodiment, the second matte layer is a second flocking layer. The second flocking layer has excellent wear resistance and effectively absorbs light. This second flocking layer further reduces the refraction of ambient light, enhancing the driver's driving experience.

[0042] The image display component is mainly used to project light onto the front windshield 500, and its structural forms are various. In this embodiment, the image display component includes a light emitting device 410, a first reflector 420 and a second reflector 430 installed in the shell 100. The light emitting device 410 can emit light to the first reflector 420, and the first reflector 420 refracts the light emitted by the light emitting device 410 to the second reflector 430. The second reflector 430 refracts the refracted light of the first reflector 420 out of the light outlet and the hole, and projects it onto the front windshield 500. The interfering light is the light refracted after being irradiated by the second reflector 430. The light emitting device 410 is an electronic component for displaying images, such as an LCD screen. Through the light emitting device 410, light is first refracted through the first reflector 420 to the second reflector 430, and then refracted from the second reflector 430 to the front windshield 500. After being refracted by the first reflector 420 and the second reflector 430, the image can be magnified and projected onto the front windshield 500 for display. In actual application, the light emitting device 410 is located between the first reflector 420 and the second reflector 430. The first reflector 420 is located relatively close to the driver relative to the second reflector 430. The external ambient light is mainly refracted by the second reflector 430 to form interference light.

[0043] The second reflector 430 is primarily used to refract the light refracted by the first reflector 420 back onto the front windshield 500. In some head-up displays, it also has the effect of magnifying the image. A plane mirror can be used for the second reflector 430. In this embodiment, the second reflector 430 is a cylindrical mirror to better converge the light and further reduce the amount of light projected onto the instrument panel 200 and instrument panel 300. Using a cylindrical mirror as the second reflector 430 helps reduce or eliminate stray light when it is refracted onto the front windshield 500. Furthermore, a cylindrical mirror can better focus light and reduce the scattering angle of light, converging ambient light that strikes the second reflector 430. This helps reduce or eliminate light reflected onto the instrument panel 200 and instrument panel 300, further minimizing the impact of ambient light on the driver's driving.

[0044] In the above embodiment, the instrument panel 300 can be a heightened structural member directly mounted on the top side of the rear portion of the instrument panel cover 200. In the present embodiment, the instrument panel 300 can also be a structural member similar to the instrument panel cover 200 and arranged around the light outlet. Specifically, Figure 2 As shown, the instrument panel 300 extends around the opening. A downward-extending stopper plate 310 is connected to the front of the instrument panel 300. The stopper plate 310 abuts the instrument panel cover 200 in front of the opening. During installation, the stopper plate 310 is inserted into the opening and abuts the instrument panel cover 200 in front of the opening, allowing the instrument panel cover 200 and the instrument panel 300 to be quickly aligned, greatly improving overall assembly efficiency. The instrument panel 300 can be further secured to the instrument panel cover 200 using snaps, screws, or adhesive, thereby creating a stepped surface between the rear of the instrument panel 300 and the rear of the instrument panel cover 200, further preventing interfering light from radiating outward. Alternatively, the instrument panel cover 200 can also be secured to the housing 100 using snaps, screws, or adhesive, providing flexible and diverse installation options.

[0045] A vehicle according to an embodiment of the second aspect of the present invention includes an instrument panel and the above-mentioned head-up display, and the housing 100 is connected to the instrument panel. The vehicle can be a private car, such as a sedan, SUV, MPV or pickup truck. The vehicle can also be an operating vehicle, such as a van, bus, small truck or large trailer. The vehicle needs to have an electric motor that can output power or store mechanical energy as a generator. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.

[0046] In this vehicle, the above-mentioned head-up display is installed on the dashboard. When the head-up display is used while driving the vehicle, the head-up display can not only reduce the external ambient light from entering the interior of the housing 100 and reducing interference with the image display component, but also effectively reduce the external ambient light from being refracted from the image display component to the instrument panel cover 200 and then refracted from the instrument panel cover 200 to the front windshield 500 to form light spots and other adverse effects, thereby improving the driver's user experience and driving safety.

[0047] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
