[0035] While the terms first, second, etc., are used in some examples herein to refer to various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, first interface and second interface, etc., are used. Furthermore, as used herein, the singular forms “a,” “an,” and “the” are intended to also include the plural forms unless the context indicates otherwise.

[0038] A head-up display (HUD), also known as a head-up display system, projects important driving information such as speed and navigation onto the windshield in front of the driver, allowing the driver to see this information without looking down or turning their head.
[0039] Currently, existing in-vehicle HUDs only have the device installed in the driver's seat. Vehicle information is transmitted to the driver's eyes through the windshield, meaning only the driver can see the information. Passengers in the front passenger seat cannot see the information, negatively impacting their riding experience.
[0040] In view of this, the present disclosure provides a device positioned between the driver and passenger seats, capable of displaying a first suspended image toward the driver's seat and a second suspended image toward the passenger's seat, so that both the driver and passenger seats can see the vehicle's driving information without interfering with each other, thus improving the passenger's riding experience.
[0041] Figure 1 shows the imaging principle diagram of the related technology. In the example in Figure 1, the optical waveguide plate 61 is set horizontally, the reflector 63 is parallel to the optical waveguide 61, and the display 62 is set at an angle relative to the horizontal plane. The display 62 is set on the side of the reflector 63 away from the windshield and closer to the driver. This arrangement, on the one hand, occupies a lot of space in the front and rear space of the vehicle body due to the limitation of the optical path, and on the other hand, it wastes part of the area of the optical waveguide plate 61 (such as the part of the optical waveguide plate 61 closer to the driver). If the front and rear space is reduced, the reflector 63 and the display 62 need to be moved towards the windshield 50, which will cause the suspended image 64 to move towards the driver, thus affecting the driver's viewing experience. The image is too large or too close, which affects driving safety. On the other hand, due to the influence of vertical space, the distance between the display component 62 and the reflector 63 is small, which makes the light path short. This results in some images not being effectively reflected. In order to ensure that the image is reflected as much as possible, the area of the reflector 63 needs to be made larger, which occupies more horizontal space in the vehicle body and further restricts the installation space of other modules in the vehicle body. At the same time, this installation method means that when providing imaging for the passenger, it can only be achieved by rotating the entire imaging device. This requires the addition of a rotating gimbal and corresponding functional circuits or devices, which further restricts the installation space.
[0042] Figure 2 shows a schematic diagram of the overall structure of the vehicle-mounted imaging device in an embodiment of this disclosure. In the example of Figure 2, the vehicle-mounted imaging device includes a housing 10, a first imaging component, a second imaging component, and an optical waveguide plate 40.
[0043] The housing 10 has a mounting cavity 101. The first imaging component and the second imaging component are symmetrically disposed in the mounting cavity 101. The light emitted by the first imaging component and / or the second imaging component forms a suspended image along the light path, the light path passing through the windshield, and the suspended image is located on the inner or outer side of the windshield. The optical waveguide plate 40 is disposed in the mounting cavity 101 and located above the first imaging component and the second imaging component. The optical waveguide plate 40 is used to mirror the light emitted by the first imaging component and / or the second imaging component and project it onto the windshield; the suspended image faces the driver's seat and / or the passenger's seat.
[0044] Exemplarily, the light path includes a first light path and a second light path. The suspended imaging includes a first suspended imaging 21 and a second suspended imaging 31. Exemplarily, the light emitted by the first imaging component forms a first suspended imaging 21 (shown in FIG. 3) located on the inner or outer side of the windshield along the first light path passing through the windshield. The light emitted by the second imaging component forms a second suspended imaging 31 (shown in FIG. 5) located on the inner or outer side of the windshield along the second light path passing through the windshield. The first suspended imaging 21 faces the driver's seat, and the second suspended imaging 31 faces the passenger's seat.
[0045] Those skilled in the art will understand that the present disclosure provides a device positioned between the driver and passenger seats, capable of displaying a first suspended image 21 facing the driver's seat and a second suspended image 31 facing the passenger's seat, so that both the driver and passenger seats can see vehicle information without interfering with each other, thus improving the passenger's riding experience.
[0046] Compared to existing imaging methods, this disclosure reduces energy consumption and equipment complexity. Furthermore, it allows for flexible adjustment of the imaging device's layout within a limited space, adapting it to the internal structures of different vehicle models and potentially reducing interference with the driver's vision. Notably, the tilted arrangement helps reduce light reflection loss between the first reflector and the waveguide plate. Therefore, compared to existing methods, this application allows light to pass through a better reflection angle before reaching the waveguide plate, reducing light loss during propagation. This enables more effective control of the light propagation path, improving imaging quality and brightness.
[0047] For example, the optical waveguide plate 40 is disposed at an angle relative to the horizontal plane in the mounting cavity 101. The optical waveguide plate 40 is used to mirror the light emitted by the first imaging component / second imaging component and direct it toward the windshield.
[0048] In the example shown in Figure 2, a light-emitting port 102 is formed on the top of the housing 10, allowing the mounting cavity 101 to communicate with the outside. That is, the light emitted by the first imaging component passes through the light waveguide plate 40 and exits through the light-emitting port 102, forming the first suspended image 21 located inside or outside the windshield after reflection by the windshield. Similarly, the light emitted by the second imaging component passes through the light-emitting port 102 after passing through the light waveguide plate 40. Exemplarily, the inner wall of the mounting cavity 101 of the housing 10 is coated with a light-shielding layer (not shown in the figure) to prevent unnecessary reflection of light from the inner wall of the housing 10, which could affect the driver's vision.
[0049] Figure 3 shows a schematic diagram of the first light path in an embodiment of this disclosure. In the example of Figure 3, the first light path is shown by the dashed line in Figure 3. In the examples of Figures 2 and 3, the first imaging assembly further includes a first display element 22 and a first reflector 23 disposed opposite to the first display element 22. The first display element 22 and the first reflector 23 in the first imaging assembly are both disposed at an angle relative to the vertical direction. Exemplarily, the distance between the first display element 22 and the first reflector 23 increases from bottom to top. The first light path is implemented as follows: the light emitted by the first display element 22 is reflected by the first reflector 23 and then directed towards the light waveguide plate 40, and after being output by the light waveguide plate 40, it is directed towards the windshield 50, and then reflected by the windshield 50 to the inner side of the windshield 50. The height of the first suspended imaging 21 is approximately at the same horizontal level as the eye level of the driver in the driver's seat.
[0050] Figure 4 shows a schematic diagram of the optical path of the first imaging component in an embodiment of this disclosure. In the example of Figure 4, the first display element 22 forms a first primary virtual image 231 in the first reflector 23, and the optical waveguide plate 40 is used to form a first secondary virtual image 51 on the first primary virtual image 231. The first secondary virtual image 51 is symmetrical about the optical waveguide plate 40 with respect to the first primary virtual image 231. At this time, the light emitted by the optical waveguide plate 40 that forms the first secondary virtual image 51 is reflected by the windshield 50, thereby forming the first suspended image 21 with the windshield 50 as the axis of symmetry and symmetrical about the first secondary virtual image 51. Those skilled in the art will understand that the first primary virtual image 231 and the first secondary virtual image 51 are not at the same horizontal level as the driver's eyeballs in the driver's seat, and the tilt angle is not suitable for the driver to view, so they will not cause visual impact on the driver.
[0051] Figure 5 shows a schematic diagram of the first light path in an embodiment of this disclosure. In the example of Figure 5, the second light path is shown by the dashed line in Figure 2. In the examples of Figures 2 and 5, the second imaging component further includes a second display element 32 and a second reflector 33 disposed opposite to the second display element 32. The second display element 32 and the second reflector 33 in the second imaging component are both disposed at an angle relative to the vertical direction. Exemplarily, the distance between the second display element 32 and the second reflector 33 moves away from bottom to top. The second light path is implemented as follows: the light emitted by the second display element 32 is reflected by the second reflector 33 and then directed towards the light waveguide plate 40, and after being output by the light waveguide plate 40, it is directed towards the windshield 50, and then reflected by the windshield 50 to the inside of the windshield 50. At this time, the height of the second suspended imaging 31 is approximately at the same level as the eye level of the passenger in the front passenger seat. At this time, the passenger does not need to spend too much energy to view relevant information, which greatly alleviates the energy consumption during the ride and has a certain auxiliary effect for long-distance driving.
[0052] Figure 6 shows a schematic diagram of the optical path of the second imaging component in an embodiment of this disclosure. In the example of Figure 6, the second display element 32 forms a second primary virtual image 331 in the second reflector 33. The optical waveguide plate 40 is used to form a second secondary virtual image 52 on the second primary virtual image 331. The second secondary virtual image 52 is symmetrical about the optical waveguide plate 40 with respect to the second primary virtual image 331. At this time, the light emitted by the optical waveguide plate 40 to form the second secondary virtual image 52 is reflected by the windshield 50, thereby forming a second suspended image 31 with the windshield 50 as the axis of symmetry and symmetrical about the second secondary virtual image 52. Those skilled in the art will understand that the second primary virtual image 331 and the second secondary virtual image 52 are not at the same horizontal level as the eyeballs of the passenger in the front passenger seat, and the tilt angle is not suitable for the passenger in the front passenger seat to view, so they will not cause visual impact on the passenger in the front passenger seat.
[0053] Exemplarily, the first display element 22 and the second display element 32 are implemented as screens capable of displaying different content, such as vehicle speed, navigation instructions, fuel consumption, etc. The first reflector 23 and the second reflector 33 are implemented as plane mirrors. Those skilled in the art will understand that the first primary virtual image 231 and the second primary virtual image 331 are formed by plane mirrors to increase the optical path within the limited space of the mounting cavity 101 of the housing 10, thereby enhancing the clarity and brightness of the display. The optical waveguide plate 40 is implemented as a planar optical waveguide plate 40.
[0054] For example, the field of view (FOV) of the first suspended image 21 is set to be invisible to the passenger seat; and / or, the field of view (FOV) of the second suspended image 31 is set to be invisible to the driver seat. Those skilled in the art will understand that the required field of view (FOV) in the embodiments of this disclosure needs to be adjusted according to the size, placement, and angle of the optical waveguide plate to achieve the above objectives.
[0055] For example, the windshield 50 is implemented as a wedge-shaped PVB film sandwiched within the interlayer. The windshield 50 acts similarly to an optical prism, changing the propagation direction of the second reflected light to the same angle of entry into the eye as the first reflected light, thereby avoiding image ghosting.
[0056] In another embodiment, the vehicle imaging may not include the optical waveguide plate. Instead, the position and angle between the first display element and the first reflector in the first imaging assembly are adjusted so that the light emitted from the first display element is reflected by the first reflector and directed towards the windshield, then reflected by the windshield to the driver's eyes, ultimately forming an image located outside the windshield in the driver's line of sight. It is understood that the second imaging assembly is configured in the same way as described above.
[0057] Figure 7 shows a top view of the vehicle-mounted imaging device in an embodiment of this disclosure. In the example of Figure 7, the length direction of the top of the first display element 22 is parallel to the length direction of the top of the first reflector 23 in the top view, and the width direction of the first suspended imaging 21 is also parallel to the length direction of the top of the first reflector 23 in the top view. Correspondingly, the length direction of the top of the second display element 32 is parallel to the length direction of the top of the second reflector 33 in the top view (as shown in Figure 7), and the width direction of the second suspended imaging 31 is also parallel to the length direction of the top of the second reflector 33 in the top view. In the example of Figure 7, the first imaging component and the second imaging component are symmetrical with respect to the central axis between the driver's seat and the passenger seat. It can be understood that the first suspended imaging 21 and the second suspended imaging 31 are also symmetrical with respect to the central axis between the driver's seat and the passenger seat.
[0058] For example, the angle between the first display element 22 and the second display element 32, as well as the angle between the first reflector 23 and the second reflector 33, are both adjustable. Further for example, the angle between the first display element 22 and the second display element 32, as well as the angle between the first reflector 23 and the second reflector 33, are adjusted synchronously so that the first suspended image 21 and the second suspended image 31 face the symmetrically arranged driver's seat and passenger seat.
[0059] Those skilled in the art will understand that the included angle between the first display element 22 and the second display element 32, and the included angle between the first reflector 23 and the second reflector 33, can be determined before assembly by taking into account the length and width of the vehicle to which the vehicle imaging device is installed, as well as the height difference between the vehicle imaging device and the driver's seat, and then, according to the determined parameters, the first display element 22 and the second display element 32, and the first reflector 23 and the second reflector 33 are fixedly connected (bolted or bonded) to the mounting cavity 101 according to the above included angle parameters.
[0060] In this embodiment, the opening at the angle between the first reflector 23 and the second reflector 33 faces the outer side of the windshield 50 (i.e., the direction of vehicle movement), thus aligning the first suspended image 21 towards the driver's seat and the second suspended image 31 towards the passenger's seat. In another embodiment, the opening at the angle between the first reflector 23 and the second reflector 33 faces the inner side of the windshield 50 (i.e., the direction of vehicle reversing), thus allowing the positions of the first and second imaging components to be interchanged, so that the first suspended image 21 faces the driver's seat and the second suspended image 31 faces the passenger's seat.
[0061] For example, the tilt angles of the first suspended image 21 and the second suspended image 31 relative to the vertical direction are both in the range of 0 degrees to 15 degrees. The advantage of this setting is that by changing the tilt angles of the first suspended image 21 and the second suspended image 31, passengers of different heights can all obtain a better visual experience. Those skilled in the art will understand that, with the tilt angle of the windshield 50 fixed, the tilt angles of the first reflector 23 and the second reflector 33 relative to the vertical direction formed by the reflection from the windshield 50 can be adjusted. Alternatively, the above objective can be achieved by adjusting the angle between the first display element 22 and the first reflector 23, or between the second display element 32 and the second reflector 33.
[0062] For example, the imaging modes of the first display 22 and the second display 32 may include RGB (red, green, blue) light-emitting diodes (LEDs), LCD (Liquid Crystal Display), LCOS (Liquid Crystal on Silicon) devices, OLED (Organic Light-Emitting Diode) arrays, projection, lasers, laser diodes, or any other suitable display or stereoscopic display, without limitation.
[0063] Another embodiment of this disclosure provides a vehicle, including the windshield 50 and the vehicle-mounted imaging device. The vehicle-mounted imaging device is disposed inside the windshield 50 and located between the driver's seat and the passenger seat. Preferably, the vehicle-mounted imaging device is located in the middle of the driver's seat and the passenger seat and does not protrude from the center console (not shown in the figure) below the windshield, so as to ensure the flatness of the vehicle's center console.
[0064] In summary, this disclosure provides a vehicle-mounted imaging device and a vehicle for its application. The vehicle-mounted imaging device includes a housing, a first imaging component, a second imaging component, and an optical waveguide plate. The housing has a mounting cavity. The first and second imaging components are symmetrically disposed in the mounting cavity. Light emitted by the first and / or second imaging components forms a suspended image along a light path, the light path passing through the windshield, and the suspended image is located inside or outside the windshield. The optical waveguide plate is disposed in the mounting cavity and above the first and second imaging components, and is used to mirror the light emitted by the first / second imaging components and project it onto the windshield; wherein the suspended image faces the driver's seat and / or the passenger's seat. The vehicle includes the windshield and the vehicle-mounted imaging device. This disclosure allows both the driver and passenger seats to see vehicle information without interference, improving the passenger experience in the passenger seat.
[0065] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
