Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a display device for a vehicle. This application also includes an instrument panel device using such a display device. Background Technology

[0002] Typically, vehicles have an instrument panel located in front of the steering wheel, which displays vehicle information (such as speed, fuel level, etc.). The driver needs to look down to read the information on the instrument panel.

[0003] In some vehicles, the windshield has a black display area adjacent to its lower edge. Vehicle driving information is projected into this display area, allowing the driver to read the information with little or no need to look down. However, the content displayed is often monotonous, which can easily cause driver eye strain. Summary of the Invention

[0004] To address the aforementioned technical problems, a first aspect of this application provides a display device for a vehicle. The display device includes a first image generating unit, a second image generating unit, and an imaging unit. The first image generating unit is adapted to generate a first luminescent image. The second image generating unit is adapted to generate a second luminescent image. The first image generating unit and the second image generating unit face each other and are spaced apart. The imaging unit is disposed between the first image generating unit and the second image generating unit. The imaging unit is semi-transparent and has an imaging surface facing the first image generating unit. Light emitted from the first luminescent image is adapted to illuminate the imaging surface, causing the first luminescent image to be displayed on the imaging surface; or light emitted from the second luminescent image is adapted to pass through the imaging unit and be displayed; or the first luminescent image and the second luminescent image are adapted to be superimposed and displayed.

[0005] In one embodiment, the first image generation unit has a planar first display surface, and the first display surface forms a first angle between 15 degrees and 90 degrees with the imaging surface.

[0006] In one embodiment, the second image generation unit has a planar second display surface, which forms a second angle with the imaging surface between 0 and 150 degrees.

[0007] In one embodiment, the imaging surface is adapted to reflect light incident on it from the first luminescent image.

[0008] In one embodiment, the imaging surface is adapted to diffusely reflect light incident on it from the first luminescent image.

[0009] In one embodiment, the first image generation unit has a planar first display surface, the first display surface has a first center point along the length direction of the vehicle, and the imaging surface has a third center point corresponding to the first center point along the length direction of the vehicle; the first distance between the first center point and the third center point is between 50mm and 300mm.

[0010] In one embodiment, the second image generation unit has a planar second display surface, and the second display surface has a second center point along the length direction of the vehicle; a third center point on the imaging surface corresponds to the second center point; and a second distance between the second center point and the third center point is between 0 mm and 200 mm.

[0011] In one embodiment, the imaging surface is adapted to specularly reflect light incident from the first luminescent image onto it, such that the imaging surface displays a virtual image of the first luminescent image. A first distance is less than a second distance, such that the virtual image is in front of the second image generation unit; or a first distance is greater than a second distance, such that the virtual image is behind the second image generation unit.

[0012] In one embodiment, the imaging surface is a plane.

[0013] In one embodiment, the imaging surface extends in an arc shape along the width direction of the vehicle.

[0014] In one embodiment, the imaging surface is arc-shaped, and the radius of the arc is between 4000mm and 8000mm.

[0015] In one embodiment, at least a portion of the imaging surface is concave.

[0016] In one embodiment, the imaging unit includes a light-transmitting main plate and a semi-transparent layer. The light-transmitting main plate has an inner surface facing the interior of the vehicle and an outer surface opposite to the inner surface. The semi-transparent layer is attached to the inner or outer surface of the main plate, or disposed inside the main plate.

[0017] In one embodiment, the second image generation unit includes a light guide plate and a light source. The light guide plate includes an incident light surface and an exit light surface. The exit light surface faces the imaging unit and is constructed with a texture corresponding to the second emitted image. The light source is configured to correspond to the incident light surface. Light emitted by the light source is adapted to enter the light guide plate through the incident light surface, exit from the exit light surface, and then pass through the imaging unit.

[0018] A second aspect of this application provides an instrument panel device. The instrument panel device includes an instrument panel body and a display device for a vehicle as described above. The instrument panel body includes a first trim panel and a second trim panel, the second trim panel being positioned above the first trim panel and defining a receiving space. A first image generating unit is assembled with the first trim panel, an imaging unit is vertically positioned between the first and second trim panels, and a second image generating unit is disposed within the receiving space.

[0019] In one embodiment, the imaging plane forms a third angle with the horizontal plane between 30 and 90 degrees.

[0020] The beneficial effects of this application are as follows: After the display device for vehicles of this application is installed on a vehicle, as needed, a first luminescent image can be displayed on the imaging surface, or a second luminescent image can be displayed through the imaging unit, or the first and second luminescent images can be superimposed. One of the first and second luminescent images can be vehicle driving information, and the other can be a background image. In this way, the display device can display multiple images, making it less likely for the driver to experience visual fatigue. In addition, the imaging unit is generally located in front of the driver, so the driver can see the vehicle driving information without looking down or with minimal need to look down, which helps to improve vehicle driving safety.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Figure 1 A vehicle 1 according to one embodiment of this application is schematically shown. Figure 1 As shown, vehicle 1 includes a windshield 101 and an instrument panel assembly 102 adjacent to the windshield 101. Figure 1 and Figure 2 As shown, the instrument panel device 102 includes an instrument panel body 2 and a display device 3 for the vehicle (hereinafter referred to as the display device 3).

[0031] like Figure 4As shown, the dashboard body 2 includes a first trim panel 201 and a second trim panel 202 that is generally positioned above the first trim panel 201 along the vehicle's height direction H. The first trim panel 201 and the second trim panel 202 extend generally along the vehicle's width direction X. In one embodiment, the first trim panel is generally parallel to the horizontal direction, and the second trim panel is configured to match the vehicle's interior environment. The second trim panel 202 also defines a receiving space 203. A display device 3 is mounted on the dashboard body 2 and spaced apart from the windshield 101 along the vehicle's length direction Y.

[0032] The display device 3 will now be described.

[0033] Reference Figure 3 and Figure 4 The display device 3 includes a first image generating unit 31, a second image generating unit 32, and an imaging unit 33. The first image generating unit 31 and the second image generating unit 32 face each other and are spaced apart. The imaging unit 33 is semi-transparent and has an imaging surface 331 and a rear surface 332 opposite to the imaging surface 331. The imaging unit 33 is disposed between the first image generating unit 31 and the second image generating unit 32, with the imaging surface 331 facing the first image generating unit 31 and the rear surface 332 facing the second image generating unit 32.

[0034] After the display device 3 is installed onto the dashboard body 2, the first image generation unit 31 is assembled with the first trim panel 201, the second image generation unit 32 is disposed within the receiving space 203, and the imaging unit 33 is positioned vertically (e.g., generally along the vehicle's height direction H) between the first trim panel 201 and the second trim panel 202. In one embodiment, the display device 3 further includes a mounting bracket 34, through which the first image generation unit 31 and the second image generation unit 32 are assembled with the dashboard body 2.

[0035] The first image generation unit 31 has a planar first display surface and is used to generate a first luminous image (not shown in the figure), and the second image generation unit 32 has a planar second display surface and is used to generate a second luminous image (not shown in the figure). The imaging surface can be configured to specularly reflect light illuminating it from the first luminous image, causing the imaging unit to display a virtual image of the first luminous image. Alternatively, the imaging surface can be configured to diffusely reflect light illuminating it from the first luminous image, causing the imaging unit to display the first luminous image. In one embodiment, the imaging surface that diffusely reflects light is a rough surface. For example, a rough surface can be formed by coating, screen printing, etching, etc., which will not be elaborated here. For simplicity, the following description uses specular reflection of light by the imaging surface as an example to illustrate the technical solution of this application.

[0036] In one embodiment, the first luminescent image includes vehicle driving information (e.g., driving information may include speed, mileage, remaining fuel, remaining battery power, warning information, navigation information, etc.). In some cases, the first luminescent image may also include a decorative pattern. The second luminescent image is a decorative pattern. Preferably, the decorative pattern does not overlap with the vehicle driving information to avoid making the vehicle driving information unclear. Of course, depending on the actual situation, the decorative pattern and the vehicle driving information may at least partially overlap. It should be understood that in some embodiments, the second luminescent image includes vehicle driving information and a decorative pattern (if any), and the first luminescent image is a decorative pattern. Alternatively, both the first and second luminescent images may include vehicle driving information and a decorative pattern (if any). For simplicity, the following description of the technical solution of this application will use the example of the first luminescent image including vehicle driving information and the second luminescent image being a decorative pattern.

[0037] When using the display device 3, after the first image generation unit 31 is lit, it generates a first luminous image. The light emitted from the first luminous image illuminates the imaging surface 331 of the imaging unit 33, causing the imaging unit 33 to display a virtual image 301 corresponding to the first luminous image, which the driver can see. After the second image generation unit 32 is lit, it generates a second luminous image. The light emitted from the second luminous image passes through the imaging unit 33, and the driver can see the second luminous image. When the first image generation unit 31 and the second image generation unit 32 are lit simultaneously, the driver can see the superimposed virtual image 301 of the first luminous image and the second luminous image. Therefore, the display device 3 of this application can display multiple images as needed, reducing driver eye fatigue.

[0038] Also refer to Figure 1 and Figure 2 The imaging unit 33 is located in front of the driver and inside the windshield 101 (e.g., the imaging unit 33 is adjacent to the windshield 101). In this way, the driver can see the vehicle's driving information displayed by the imaging unit 33 without having to look down or with minimal need to look down, which helps improve the safety of driving.

[0039] For example Figure 4 As shown, the second image generating unit 32 is disposed within the receiving space 203. In this way, light from the external environment will not illuminate the rear surface 332 of the imaging unit 33, nor will it illuminate the second image generating unit 32, which helps to make the second luminous image display clearer.

[0040] The imaging surface 331 extends generally in an arc shape along the width direction X of the vehicle to match the vehicle's shape. The shape of the first image generating unit 31 matches the shape of the imaging surface 331. In this way, both the area of ​​the first image generating unit 31 and the area of ​​the imaging surface 331 are relatively large, enabling the display device to display rich information and / or patterns.

[0041] In one embodiment, the imaging surface 331 extends in an arc shape along the width direction of the vehicle. For example, the radius of the arc is between 4000mm and 8000mm. In this way, the driver is less likely to experience dizziness when viewing the virtual image of the first luminous image and / or the second luminous image while the vehicle is in motion, which helps to improve the driver's driving experience.

[0042] In one embodiment, the imaging surface is concave. This concave surface bulges generally toward the windshield. In other words, the imaging surface is generally grooved along the width direction X of the vehicle, so that the cross-section of the imaging surface along the height direction H of the imaging unit is generally arc-shaped. Alternatively, the imaging surface can be concave and extend generally along the width direction X of the vehicle in an arc shape, which will not be elaborated here. Of course, depending on the actual situation, a portion of the imaging surface can also be constructed as concave.

[0043] In one embodiment, the imaging surface 331 is planar. This ensures that the virtual image of the first luminescent image and the second luminescent image are essentially undistorted, helping the driver to clearly read vehicle driving information.

[0044] In one embodiment, the first display surface of the first image generation unit 31 forms a first angle between 15 and 90 degrees with the imaging surface 331. For example, the angle of the first angle can be 15, 40, 50, 60, 65, 70, or 90 degrees. The imaging surface 331 forms a third angle between 30 and 90 degrees with the horizontal plane. For example, the angle of the third angle can be 30, 45, 50, 60, 65, 70, or 90 degrees. This allows the virtual image 301 of the first luminescent image displayed by the imaging unit 33 to be substantially vertical, facilitating the driver's reading of vehicle driving information. Of course, depending on the actual situation, the first and third angles can also be other angles, which will not be elaborated here.

[0045] In one embodiment, the first angle between the first display surface and the imaging surface 331 of the first image generation unit 31 is between 15 degrees and 90 degrees (as described above). The second display surface of the second image generation unit 32 forms a second angle between the second display surface and the imaging surface 331 between 0 degrees and 150 degrees. For example, the second angle can be 0 degrees, 30 degrees, 45 degrees, 60 degrees, 70 degrees, 90 degrees, 100 degrees, or 150 degrees. This allows the virtual image of the first luminous image and / or the second luminous image to be well superimposed and displayed.

[0046] For example Figure 4 As shown, the first display surface of the first image generation unit 31 has a first center point 315 along the length Y direction of the vehicle, the second display surface of the second image generation unit 32 has a second center point 325 along the length Y direction of the vehicle, and the imaging surface 331 has a third center point 335 along the length Y direction of the vehicle. The third center point 335 corresponds to the first center point 315 and the second center point 325. There is a first distance between the first center point 315 and the third center point 335, and there is a second distance between the second center point 325 and the third center point 335. For example, the first distance is between 50mm and 300mm, and the second distance is between 0mm and 200mm. In this way, the thickness of the display device 3 is small, which facilitates the use of the display device 3 in a confined space.

[0047] As needed, the first distance can be greater than the second distance, so that the virtual image 301 of the first luminescent image is located behind the second image generation unit 32 (e.g., Figure 4 (As shown), or by making the first distance smaller than the second distance, so that the virtual image 301 of the first luminous image is in front of the second image generation unit 32. In this way, the driver can perceive the layering of the superimposed virtual image of the first luminous image and / or the second luminous image, thereby further improving the display effect of the display device 3. Of course, the virtual image of the first luminous image can also be positioned on the second image generation unit 32 by adjusting the first distance and / or the second distance.

[0048] For example Figure 2 As shown, the display device 3 also includes two electronic rearview mirrors 205. The two electronic rearview mirrors 205 are positioned on either side of the imaging unit 33 along the width direction X of the vehicle. For example, the two electronic rearview mirrors 205 are connected to the imaging unit 33. Thus, while the vehicle is in motion, the driver can not only see the image of the vehicle's driving information displayed by the imaging unit 33, but also conveniently see the surrounding environment of the vehicle through the two electronic rearview mirrors 205, thereby helping to improve the driver's driving experience.

[0049] In one embodiment, such as Figure 5As shown, the second image generation unit 32 includes a light guide plate 321 and a light source 322. The light guide plate 321 has an incident light surface 323 and an emitting light surface 324. For example, the incident light surface 323 is an edge surface of the light guide plate 321, and the emitting light surface 324 faces the imaging unit 33 and forms a second display surface. A texture (not shown in the figure) corresponding to the second emitted image is also formed on the emitting light surface 324. The light source 322 is, for example, an LED and is configured to correspond to the incident light surface 323. In this way, the second image generation unit 32 is a side-lit backlight type, which makes the thickness of the second image generation unit 32 smaller, making it easier for the second image generation unit 32 to be used in a confined space. The light guide plate is well known to those skilled in the art and will not be described in detail here.

[0050] After the light source 322 is lit, the light emitted by the light source 322 enters the light guide plate 321 through the light incident surface 323, exits from the light emitting surface 324, and then passes through the imaging unit 33. In this way, the driver can see the second luminous image through the imaging unit. It should be understood that, in this case, the second luminous image is a static pattern. As an example, the second luminous image includes at least one of the following: brushed pattern, checkered pattern, starry sky pattern, imitation stone pattern, wood grain pattern, fabric pattern, landscape pattern, crystal pattern, three-dimensional relief, text, letters, graphics, symbols, numbers, beacons, and trademarks. In one embodiment, the texture on the light guide plate may also be colored, so that the second luminous image is colored to improve the display effect of the display device.

[0051] Depending on the specific requirements, the second image generation unit may include multiple light guide plates. These light guide plates are stacked, and each light guide plate has a different texture. Furthermore, a light source is provided for each of these light guide plates. Thus, by controlling the illumination and extinguishing of these light sources, the second luminous image generated by the second image generation unit can correspond to the texture on one light guide plate, or it can correspond to the superposition of textures on multiple light guide plates. Therefore, the display device can display various images as needed, reducing driver visual fatigue.

[0052] The second image generation unit can also be a display panel to display appropriate decorative patterns. The decorative patterns can be dynamic or static. For example, the display panel can be an LCD panel, OLED panel, MiniLED panel, QD-MiniLED panel, or MicroLED panel. Of course, depending on the actual situation, the second image generation unit can also be in other forms, which are not limited here. Furthermore, the second image generation unit can be composed of multiple display panels spliced ​​along the width direction X of the vehicle, or it can be a single display panel. The same applies to the first image generation unit, which will not be elaborated further here.

[0053] Figure 6a , Figure 6b and Figure 6cSome embodiments of the imaging unit are shown schematically.

[0054] like Figure 6a As shown, the imaging unit 33 includes a light-transmitting main plate 336 and a semi-transparent and semi-reflective layer 337 attached to the main plate 336.

[0055] The main body plate 336 has an inner surface 338 facing the interior of the vehicle and an outer surface 339 opposite to the inner surface 338.

[0056] The semi-transparent and semi-reflective layer 337 is, for example, implemented as an optical film. Such optical films are well known to those skilled in the art and will not be described in detail here. The optical film can be disposed on the inner surface 338 of the body plate 336 (e.g., Figure 6a (As shown). It should be understood that, as Figure 6b As shown, the optical film can also be disposed on the outer surface 339 of the main body plate 336. Also as... Figure 6c As shown, the optical film can also be disposed inside the main body plate 336. For example, the main body plate 336 includes a first plate 333 and a second plate 334 stacked together, with the optical film sandwiched between the first plate 333 and the second plate 334.

[0057] In one embodiment, the semi-transparent and semi-reflective layer may also be a coating layer applied to the main body panel, which will not be described in detail here.
