[0039] Head-up display (HUD) technology is increasingly used in automobiles. It improves driving safety and convenience by projecting important driving information, including but not limited to driving speed, mileage, fuel level, safe distance, surrounding obstacles, reversing images, etc., into the driver's field of vision.

[0040] The dual-focal length HUD can display information on different focal planes, such as close focus to display vehicle speed and vehicle status, and far focus to display navigation and traffic information, further improving the convenience of driving. The dual-focal length HUD can provide an immersive experience for drivers, by displaying information on different focal planes, providing richer information display, and enhancing the three-dimensional sense and immersiveness of information.

[0041] However, the dual-focal length HUD in related technologies is usually large in size and difficult to achieve miniaturized design.

[0042] Based on this, the present application provides a head-up display device and a vehicle, which can realize dual-focal plane display while reducing the size of the head-up display device, thereby facilitating the miniaturization design of the head-up display device.

[0043] Referring to FIG. 1 and FIG. 2 , FIG. 1 is a schematic diagram of the structure of a head-up display device 10 in an embodiment of the present application. FIG. 2 is a schematic diagram of the light path propagation of the head-up display device 10 in an embodiment of the present application. The head-up display device 10 includes a light-emitting element 100, a first optical component 300, and a second optical component 400. The light-emitting element 100 is used to emit a first imaging light 110 and a second imaging light 120.

[0044] In some embodiments, the first imaging light 110 forms a near-focus image, which can be used to display basic information such as vehicle speed and fuel level, etc. The second imaging light 120 forms a far-focus image, which can be used to display complex information such as vehicle navigation and traffic signs.

[0045] The first optical component 300 is disposed on the light-emitting side of the light-emitting element 100, and the first optical component 300 is used to receive the first imaging light 110 and form a first virtual image on the first imaging plane. The second optical component 400 is disposed on the light-emitting side of the light-emitting element 100 and is adjacent to the first optical component 300. The second optical component 400 is used to receive the second imaging light 120 and form a second virtual image on the second imaging plane. The first imaging plane and the second imaging plane are different imaging planes.

[0046] In this way, the two paths of imaging light are transmitted respectively through the first optical component 300 and the second optical component 400, thereby reducing the risk of mutual interference between the two paths of imaging light, and further facilitating the improvement of the imaging quality of far-focus and near-focus images.

[0047] The head-up display device 10 of the present application can realize dual-path propagation by using one light-emitting element 100 to form two virtual images. Compared with the related art in which two light-emitting elements 100 are used to emit two paths of light respectively, the head-up display device 10 of the present application can realize dual-focal plane display while being conducive to realizing the miniaturized design of the head-up display device 10 of the present application. The first optical component 300 and the second optical component 400 of the present application are arranged adjacent to each other, which is conducive to further reducing the volume of the head-up display device 10 and facilitating the miniaturized design of the head-up display device 10.

[0048] In some embodiments, the partition plate 200 is disposed on the light-emitting side of the light-emitting element 100 and is disposed between the first imaging light 110 and the second imaging light 120 to avoid interference between the far-focus image and the near-focus image. The arrangement of the partition plate 200 is conducive to improving the imaging quality of the far-focus image and the near-focus image. At the same time, the first optical component 300 and the second optical component 400 are arranged to respectively transmit the two imaging lights, further reducing the risk of mutual interference between the two imaging lights, thereby further helping to improve the imaging quality of the far-focus image and the near-focus image.

[0049] In some embodiments, referring to FIG. 1 and FIG. 2 , the first optical assembly 300 includes a first near-focus optical element 310 and a second near-focus optical element 320. Along the propagation direction of the first imaging light 110 emitted by the light emitting element 100, the first near-focus optical element 310 and the second near-focus optical element 320 are sequentially arranged between the light emitting element 100 and the first imaging surface to propagate the first imaging light 110 to the first imaging surface. In this way, the first imaging light 110 emitted by the light emitting element 100 passes through the first near-focus optical element 310 and the second near-focus optical element 320 in sequence, and finally propagates to the first imaging surface for imaging. The design of two near-focus optical elements is conducive to effectively reducing aberrations, improving imaging quality, improving light efficiency and brightness, and forming clear and accurate images. At the same time, there is no need for too many optical lenses to propagate light, which is conducive to further reducing the volume of the head-up display device 10 and realizing the miniaturization design of the head-up display device 10.

[0050] In some embodiments, as shown in FIG2 , the first near-focus optical element 310 and the second near-focus optical element 320 are both reflective optical elements, and the reflective surface of the first near-focus optical element 310 faces the light-emitting element 100 to reflect the first imaging light 110 to the second near-focus optical element 320. It can be understood that the reflective surfaces of the first near-focus optical element 310 face the light-emitting element 100 and the second near-focus optical element 320, respectively. In this way, the first imaging light 110 emitted by the light-emitting element 100 is repeatedly bent, which is beneficial to reducing the volume of the head-up display device 10 and facilitating the miniaturization design of the head-up display device 10.

[0051] In some embodiments, the first near-focus optical element 310 is a fixed mirror, that is, a micro-electromechanical system micro-vibration mirror, which can accurately control the propagation direction of light. It has the advantages of miniaturization and high integration, so it is easy to be integrated into the housing of the head-up display device 10, which is convenient for realizing the miniaturization design of the head-up display device 10. The first near-focus optical element 310 uses a fixed mirror, which also has the advantage of fast response, can quickly adjust the direction of light, and is conducive to improving the image display effect.

[0052] In some embodiments, the second near-focus optical element 320 is a rotating mirror, that is, a polyhedral rotating scanning mirror, whose side is coated with a reflective layer. When the rotating mirror rotates at high speed driven by the electrode, the light is incident on the rotating mirror surface, and the reflected light will sweep out a bright line to form a grating, thereby realizing the reflection and propagation of the light. In this way, the second near-focus optical element 320 has the advantage of a wide scanning range. The rotating mirror can cover a larger scanning range by rotation, which is conducive to having a wider field of view. At the same time, the second near-focus optical element 320 also has the advantages of simple structure, low cost and maintenance cost, and the ability to dynamically adjust the position of the dotted line to further improve the display effect.

[0053] In some embodiments, referring to FIG. 1 and FIG. 2 , the second optical assembly 400 includes a first afocal optical element 410 and a second afocal optical element 420. Along the propagation direction of the second imaging light 120 emitted by the light emitting element 100, the first afocal optical element 410 and the second afocal optical element 420 are sequentially arranged between the light emitting element 100 and the second imaging plane to propagate the second imaging light 120 to the second imaging plane. In this way, the second imaging light 120 emitted by the light emitting element 100 passes through the first afocal optical element 410 and the second afocal optical element 420 in sequence, and finally propagates to the second imaging plane for imaging. The design of two afocal optical elements is conducive to effectively reducing aberrations, improving imaging quality, improving light efficiency and brightness, and forming clear and accurate images. At the same time, there is no need for too many optical lenses to propagate light, which is conducive to further reducing the volume of the head-up display device 10 and realizing the miniaturization design of the head-up display device 10.

[0054] In some embodiments, referring to FIG. 1 and FIG. 2 , the first far-focus optical element 410 and the first near-focus optical element 310 are arranged side by side on the light-emitting side of the light-emitting element 100, and along the first direction F1, the first far-focus optical element 410 and the first near-focus optical element 310 are arranged at intervals. The second near-focus optical element 320 is arranged on one side of the first near-focus optical element 310 along the second direction F2, and the second far-focus optical element 420 is arranged on one side of the first far-focus optical element 410 along the second direction F2, and along the first direction F1, the second near-focus optical element 320 and the second far-focus optical element 420 are arranged at intervals. The first direction F1 and the second direction F2 intersect with each other. In other words, the first far-focus optical element 410 and the first near-focus optical element 310 are arranged adjacent to each other, and the second far-focus optical element 420 and the second near-focus optical element 320 are arranged adjacent to each other. In this way, the distance between the first optical component 300 and the second optical component 400 is reduced, the volume of the head-up display device 10 is further reduced, and the miniaturized design of the head-up display device 10 is realized.

[0055] In some embodiments, the first afocal optical element 410 and the second afocal optical element 420 are both reflective optical elements, and the reflective surface of the first afocal optical element 410 faces the light emitting element 100 to reflect the second path of imaging light 120 to the second afocal optical element 420. It can be understood that the reflective surfaces of the first afocal optical element 410 face the light emitting element 100 and the second afocal optical element 420 respectively, and such an arrangement makes the second path of imaging light 120 emitted by the light emitting element 100 bend repeatedly, which is beneficial to reducing the volume of the head-up display device 10 and realizing the miniaturized design of the head-up display device 10.

[0056] In some embodiments, the first afocal optical element 410 is a fixed mirror, that is, it can be a micro-electromechanical system micro-vibration mirror, which can accurately control the propagation direction of light. Therefore, the first afocal optical element 410 has the advantages of miniaturization and high integration, which is conducive to the integration and installation of the first afocal optical element 410 into the housing of the head-up display device 10, and is convenient for realizing the miniaturization design of the head-up display device 10. The first afocal optical element 410 adopts a fixed mirror, which also has the advantage of fast response, can quickly adjust the direction of light, and is conducive to improving the image display effect.

[0057] In some embodiments, the second afocal optical element 420 is a rotating mirror. That is, it can be a polyhedral rotating scanning mirror, and a reflective layer is plated on its side. When the rotating mirror rotates at high speed driven by the electrode, the light is incident on the rotating mirror surface, and the reflected light will sweep out a bright line to form a grating, thereby realizing the reflection and propagation of the light. The second afocal optical element 420 has the advantage of a wide scanning range. The rotating mirror can cover a larger scanning range by rotation, which is conducive to having a wider field of view. At the same time, the second afocal optical element 420 also has the advantages of simple structure, low cost and maintenance cost, and can dynamically adjust the position of the dotted line to further improve the display effect.

[0058] In some embodiments, the first near-focus optical element 310, the second near-focus optical element 320, the first far-focus optical element 410 and the second far-focus optical element 420 are all formed by coating an aluminum film layer on the surface of a base layer. In this way, a small amount of stray light generated by the mutual interference of a small part of the first imaging light 110 and the second imaging light 120 can be absorbed by the first near-focus optical element 310, the second near-focus optical element 320, the first far-focus optical element 410 and the second far-focus optical element 420, which helps to further weaken the interference between the first imaging light 110 and the second imaging light 120, and helps to improve the dual-light path imaging quality of the head-up display device 10.

[0059] In some embodiments, referring to FIG. 1 and FIG. 2, in combination with FIG. 3, FIG. 3 is a schematic diagram of the structure of the partition plate 200 and the light-emitting element 100 in one embodiment of the present application. The light-emitting element 100 includes a light-emitting surface, and the light-emitting surface includes a first light-emitting portion 130 and a second light-emitting portion 140. The first light-emitting portion 130 is used to emit a first imaging light 110, and the second light-emitting portion 140 is used to emit a second imaging light 120. The partition plate 200 is arranged between the first light-emitting portion 130 and the second light-emitting portion 140. In this way, the first light-emitting portion 130 and the second light-emitting portion 140 emit light independently, which is conducive to improving the imaging quality of the first imaging light 110 and the second imaging light 120.

[0060] The present application also provides a vehicle, characterized in that it includes the head-up display device 10 and the windshield 500 described in any of the above embodiments. In some embodiments, the first imaging plane and the second imaging plane are both located on the windshield 500 and are located at different positions of the windshield 500, so as to achieve far-focus and near-focus imaging. The first imaging light 110 emitted by the first light-emitting portion 130 of the light-emitting element 100 of the head-up display device 10 passes through the first near-focus optical element 310 and the second near-focus optical element 320 in sequence to form a first virtual image on the first imaging plane, and the second imaging light 120 emitted by the second light-emitting portion 140 of the light-emitting element 100 passes through the first far-focus optical element 410 and the second far-focus optical element 420 in sequence to form a second virtual image on the second imaging plane, so as to achieve dual-focal plane display.

[0061] The head-up display device 10 of the present application can realize dual-path propagation by using one light-emitting element 100 to form two virtual images. Compared with the related art in which two light-emitting elements 100 are used to emit two paths of light respectively, the head-up display device 10 of the present application can realize dual-focal plane display while being conducive to realizing the miniaturized design of the head-up display device 10 of the present application. In addition, the first optical component 300 and the second optical component 400 of the present application are arranged adjacent to each other, which is conducive to further reducing the volume of the head-up display device 10 and facilitating the miniaturized design of the head-up display device 10. At the same time, the partition plate 200 is arranged between the first imaging light 110 and the second imaging light 120 to avoid mutual interference between the far-focus and near-focus images, and the first optical component 300 and the second optical component 400 are arranged to respectively propagate the two imaging lights, further reducing the risk of mutual interference between the two imaging lights, thereby further facilitating improving the imaging quality of the far-focus and near-focus images.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
