[0044] The head-up display system (HUD), also known as the 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 important driving information such as speed and navigation without lowering or turning his head.

[0045] At present, the existing vehicle HUDs are installed only in the main driver's seat, and the vehicle information is transmitted to the driver's eyes through the windshield of the main driver's side, so that only the main driver's seat can see the corresponding vehicle information. The passenger sitting in the co-pilot seat cannot see it, which affects the passenger's riding experience.

[0046] In view of this, the embodiment of the present disclosure provides a device which is located between the main driver's seat and the co-pilot's seat and can present a first suspended imaging toward the main driver's seat and a second suspended imaging toward the co-pilot's seat, so that both the main driver's seat and the co-pilot's seat can see the vehicle's driving information without interfering with each other, thereby improving the riding experience of the co-pilot's seat passenger.

[0047] Figure 1 The imaging principle diagram of the related technology is shown in FIG. Figure 1 In the example, in the related art, the light guide plate 61 is horizontally arranged, the reflector 63 is parallel to the light guide 61, the display element 62 is inclined relative to the horizontal plane, and the display element 62 is arranged on the side of the reflector 63 away from the windshield and close to the driver. On the one hand, due to the limitation of the light path, this method will occupy more space in the front and rear space of the vehicle body, and will cause part of the area of ​​the light guide plate 61 to be wasted (such as the part of the light guide plate 61 close to the driver's side). If the front and rear space is reduced, the reflector 63 and the display element 62 need to be moved toward the windshield direction 50, which will cause the suspended image 64 to move toward the driver, thereby causing the driver to see 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 element 62 and the reflector 63 is small, which makes the light path shorter and causes part of the image to be unable to be effectively reflected. In order to ensure that the image is reflected as much as possible, it is necessary to make the area of ​​the reflector 63 larger, which occupies more horizontal space in the vehicle body, further limiting the installation space of other modules in the vehicle body. At the same time, this installation method results in that when providing imaging for the co-pilot, it can only be achieved by rotating the entire imaging device, which requires the additional addition of a rotating gimbal and corresponding functional circuits or devices, which further limits the installation space.

[0048] Figure 2 The figure shows the overall structure of the vehicle-mounted imaging device in the embodiment of the present disclosure. Figure 2 In the example, the vehicle-mounted imaging device includes a housing 10 , a first imaging component, a second imaging component and an optical waveguide plate 40 .

[0049] The housing 10 has a mounting cavity 101. The first imaging component and the second imaging component are symmetrically arranged in the mounting cavity 101. The light emitted by the first imaging component and / or the second imaging component forms a suspended imaging along the light path, and the light path passes through the windshield, and the suspended imaging is located on the inside or outside of the windshield. The optical waveguide plate 40 is arranged in the mounting cavity 101 and is 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 then project it toward the windshield; the suspended imaging is directed toward the main driver's seat and / or the co-driver's seat.

[0050] 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 ( 31 ) located inside or outside the windshield along the first light path passing through the windshield. Figure 3 The light emitted by the second imaging component forms a second suspended image 31 (located inside or outside the windshield) along the second light path passing through the windshield. Figure 5 ). The first suspended image 21 is oriented toward the main driver's seat, and the second suspended image 31 is oriented toward the co-driver's seat.

[0051] Those skilled in the art will appreciate that the embodiment of the present disclosure provides a device that is located in the middle of the main and co-pilot seats and can present a first suspended image 21 toward the main driver's seat and a second suspended image 31 toward the co-pilot seat, so that both the main and co-pilot seats can see the vehicle information without interfering with each other, thereby improving the riding experience of the co-pilot seat passenger.

[0052] Compared with the imaging method in the prior art, the present invention reduces energy consumption on the one hand and the complexity of the equipment on the other hand, and can flexibly adjust the layout of the imaging device within a limited space to adapt it to the internal structure of different vehicle models, while also potentially reducing interference with the driver's line of sight; it is worth mentioning that since the inclined setting helps to reduce the reflection loss of light between the first reflector and the optical waveguide plate, the present application can allow the light to pass through a more optimal reflection angle before reaching the optical waveguide plate, thereby reducing the loss of light during the propagation process, thereby more effectively controlling the propagation path of the light and improving the quality and brightness of the imaging.

[0053] Exemplarily, the optical waveguide plate 40 is disposed in the installation cavity 101 at an angle relative to a horizontal plane. The optical waveguide plate 40 is used to mirror the light emitted by the first imaging component / the second imaging component and then emit it to the windshield.

[0054] exist Figure 2 In the example, a light outlet 102 is formed on the top of the housing 10 for connecting the mounting cavity 101 with the outside. That is, the light emitted by the first imaging component is emitted from the light outlet 102 after passing through the optical waveguide plate 40, and forms the first suspended image 21 located on the inside or outside of the windshield after being reflected by the windshield. The light emitted by the second imaging component also passes through the light outlet 102 after passing through the optical 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 on the inner wall of the housing 10 and affect the driver's sight.

[0055] Figure 3 , which is a schematic diagram of the first light path in the embodiment of the present disclosure. Figure 3 In the example, the first light path is as follows Figure 3 Indicated by the dashed line. Figure 2 and Figure 3 In the example, the first imaging component also includes a first display element 22 and a first reflector 23 arranged opposite to the first display element 22. The first display element 22 and the first reflector 23 in the first imaging component are both arranged obliquely relative to the vertical direction. Exemplarily, the distance between the first display element 22 and the first reflector 23 is farther 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 emitted to the optical waveguide plate 40, and then emitted to the windshield 50 after being output by the optical waveguide plate 40, and then reflected by the windshield 50 to the inner side of the windshield 50. The height of the first suspended imaging 21 is roughly on the same horizontal plane as the eye height of the driver in the main driving seat.

[0056] Figure 4 The figure shows a schematic diagram of the optical path of the first imaging component in the embodiment of the present disclosure. Figure 4 In the example, the first display element 22 forms a first main virtual image 231 in the first reflective element 23, and the optical waveguide plate 40 is used to form a first secondary virtual image 51 for the first main virtual image 231, wherein the first secondary virtual image 51 is symmetrical with respect to the first main virtual image 231 with the optical waveguide plate 40 as the axis of symmetry, and the light output by the optical waveguide plate 40 to form 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 with the first secondary virtual image 51. It can be understood by those skilled in the art that the first main virtual image 231 and the first secondary virtual image 51 are not in the same horizontal plane as the eyeball height of the driver in the main driving seat, and the inclination angle is not suitable for the driver in the main driving seat to watch, so it will not cause visual impact on the driver in the main driving seat.

[0057] Figure 5 , which is a schematic diagram of the first light path in the embodiment of the present disclosure. Figure 5 In this example, the second light path is as follows: Figure 2 Indicated by the dashed line. Figure 2 and Figure 5In the example, the second imaging assembly further includes a second display element 32 and a second reflector 33 arranged opposite to the second display element 32. The second display element 32 and the second reflector 33 in the second imaging assembly are both arranged obliquely relative to the vertical direction. Exemplarily, the distance between the second display element 32 and the second reflector 33 is away from each other 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 emitted to the light waveguide plate 40, and then emitted to the windshield 50 after being output by the light waveguide plate 40, and then reflected to the inner side of the windshield 50 by the windshield 50. At this time, the height of the second suspended imaging 31 is roughly at the same level as the eye height of the passenger in the co-pilot seat. At this time, the passenger does not need to spend too much energy to view the relevant information, which greatly alleviates the energy loss during the ride, which has a certain auxiliary effect for remote driving.

[0058] Figure 6 The figure shows a schematic diagram of the optical path of the second imaging component in the embodiment of the present disclosure. Figure 6 In the example, the second display element 32 forms a second main virtual image 331 in the second reflective element 33, and the optical waveguide plate 40 is used to form a second secondary virtual image 52 for the second main virtual image 331, wherein the second secondary virtual image 52 is symmetrical with respect to the second main virtual image 331 with the optical waveguide plate 40 as the axis of symmetry, and the light output by the optical waveguide plate 40 to form the second secondary virtual image 52 is reflected by the windshield 50, thereby forming the second suspended image 31 with the windshield 50 as the axis of symmetry and symmetrical with the second secondary virtual image 52. It can be understood by those skilled in the art that the second main virtual image 331 and the second secondary virtual image 52 are not at the same level as the eyeball height of the passenger in the front passenger seat, and the inclination angle is not suitable for the passenger in the front passenger seat to watch, so it will not cause visual impact on the passenger in the front passenger seat.

[0059] Exemplarily, the first display element 22 and the second display element 32 are implemented as screens that can display different contents, such as vehicle speed, navigation instructions, fuel consumption, etc. The first reflector 23 and the second reflector 33 are implemented as plane reflectors. It can be understood by those skilled in the art that the first main virtual image 231 and the second main virtual image 331 are formed by plane reflectors to increase the optical path in the limited installation cavity 101 of the housing 10, thereby enhancing the clarity and brightness of the display. The optical waveguide plate 40 is implemented as a plane optical waveguide plate 40.

[0060] Exemplarily, the field of view (FOV) of the first suspended imaging 21 is set to be invisible to the co-pilot seat; and / or the field of view (FOV) of the second suspended imaging 31 is set to be invisible to the main driver's seat. It can be understood by those skilled in the art that the field of view (FOV) required in the embodiment of the present disclosure needs to be adjusted according to the size, placement position and angle of the optical waveguide plate to meet the above purpose.

[0061] Exemplarily, the windshield 50 is implemented as a wedge-shaped PVB film inside the interlayer. The windshield 50 plays a role similar to an optical prism, changing the propagation direction of the second reflected light to the same angle as the first reflected light, thereby avoiding image ghosting.

[0062] In another embodiment, the vehicle-mounted imaging may not include the optical waveguide plate, and only by adjusting the position and angle between the first display element and the first reflector in the first imaging assembly, the light hole emitted by the first display element is reflected by the first reflector and then emitted to the windshield, and then reflected by the windshield to the driver's eyes, and finally an image located outside the windshield is formed in the driver's sight. It can be understood that the setting method of the second imaging assembly is the same as the above method.

[0063] Figure 7 FIG. 1 is a top view of a vehicle-mounted imaging device in an embodiment of the present disclosure. Figure 7 In the example, 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 a top view, and the width direction of the first suspended image 21 is also parallel to the length direction of the top of the first reflector 23 in a 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 a top view (such as Figure 7 The width direction of the second suspended image 31 is also parallel to the length direction of the top of the second reflector 33 in a top view. Figure 7 In the example, the first imaging component and the second imaging component are symmetrical relative to the central axis between the main driving seat and the co-pilot seat. It can be understood that the first suspended imaging 21 and the second suspended imaging 31 are also symmetrical relative to the central axis between the main driving seat and the co-pilot seat.

[0064] Exemplarily, the angle between the first display element 22 and the second display element 32 and the angle between the first reflector 23 and the second reflector 33 are both adjustable. Further exemplarily, the angle between the first display element 22 and the second display element 32 and the angle between the first reflector 23 and the second reflector 33 are synchronously adjusted to make the first suspended image 21 and the second suspended image 31 face the symmetrically arranged main driving seat and the co-driving seat.

[0065] Those skilled in the art may understand that, before assembly, the angle between the first display component 22 and the second display component 32 and the angle between the first reflector 23 and the second reflector 33 may be considered as a whole and the angle parameters may be determined based on the length and width of the vehicle on which the vehicle-mounted imaging device is installed and the height difference between the vehicle-mounted imaging device and the driver's seat, and then, based on the determined parameters, the first display component 22 and the second display component 32 and the first reflector 23 and the second reflector 33 may be fixedly connected (bolted or bonded) to the mounting cavity 101 according to the above-mentioned angle parameters.

[0066] In this embodiment, the opening of the angle between the first reflector 23 and the second reflector 33 faces the outside of the windshield 50 (i.e., the direction in which the vehicle is moving forward), so that the first suspended imaging 21 faces the main driver's seat, and the second suspended imaging 31 faces the co-driver's seat. In another embodiment, the opening of the angle between the first reflector 23 and the second reflector 33 faces the inside of the windshield 50 (i.e., the direction in which the vehicle is moving backward), so that the first suspended imaging 21 faces the main driver's seat, and the second suspended imaging 31 faces the co-driver's seat by swapping the positions of the first imaging component and the second imaging component.

[0067] Exemplarily, the inclination angle range of the first suspended image 21 and the second suspended image 31 relative to the vertical direction is 0 degrees to 15 degrees. The advantage of the above arrangement is that by changing the inclination angle of the first suspended image 21 and the second suspended image 31, passengers of different heights can obtain a better visual experience. It can be understood by those skilled in the art that, when the inclination angle of the windshield 50 is fixed, the inclination angle of the first suspended image 21 / the second suspended image 31 formed by the reflection of the windshield 50 relative to the vertical direction can be adjusted by changing the angle of the first reflector 23 / the second reflector 33. Alternatively, the above purpose can be achieved by adjusting the angle between the first display element 22 and the first reflector 23 / the second display element 32 and the second reflector 33.

[0068] Exemplarily, the imaging modes of the first display element 22 and the second display element 32 may include RGB (red, green, blue) light emitting diodes (LED), LCD (Liquid Crystal Display), LCOS (Liquid Crystal on Silicon) devices, OLED (Organic Light-Emitting Diode) arrays, projections, lasers, laser diodes or any other suitable displays or stereoscopic displays, without limitation.

[0069] Another embodiment of the present disclosure provides a vehicle, comprising the windshield 50 and the vehicle-mounted imaging device. The vehicle-mounted imaging device is disposed inside the windshield 50 and between the main driver's seat and the co-driver's seat. Preferably, the vehicle-mounted imaging device is disposed in the middle of the main driver's seat and the co-driver's seat and does not protrude from the center console (not shown in the figure) below the windshield to ensure the flatness of the vehicle center console.

[0070] In summary, the embodiments of the present disclosure provide a vehicle-mounted imaging device and a vehicle using the same, wherein the vehicle-mounted imaging device comprises a housing, a first imaging component, a second imaging component and an optical waveguide plate. The housing has a mounting cavity. The first imaging component and the second imaging component are symmetrically arranged in the mounting cavity.

The vehicle comprises the windshield and the vehicle-mounted imaging device. The embodiments of the present disclosure enable both the main and co-pilot seats to see the information of the vehicle without interfering with each other, thereby improving the riding experience of the co-pilot seat passenger.
