[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0031] According to the first aspect of this application, referring to Figures 1 to 6 This disclosure provides a head-up display device 100, which may be used, but is not limited to, in aircraft, vehicles and other means of transportation.

[0032] The head-up display 100 emits light to the eye box 400, which is a three-dimensional area within the head-up display 100 where the user's eyes can move, and within this area, the user can clearly see the information projected by the head-up display 100.

[0033] The head-up display device 100 is provided with an information display area 210. Taking the application of the head-up display device 100 in a vehicle as an example, the information display area 210 may display, but is not limited to, vehicle speed information, navigation instruction information, or track information, etc.

[0034] The information display area 210 can be located at different positions on the head-up display device 100, with each information display area 210 corresponding to a different position of the eye box 400. It can be understood that the head-up display device 100 changes the position of the information display area 210 to alter its optical path, thereby changing the position of the eye box 400 to meet the user's needs for the eye box 400 in different positions.

[0035] There are many ways to position the information display area 210 at different locations on the head-up display device 100. In some embodiments, the head-up display device 100 includes a display area, and the information display area 210 can be located at different positions within that display area. For example, the head-up display device 100 includes a first display unit with a display area, and the information display area 210 can be located at different positions within that display area. This allows the head-up display device 100 to change the position of the eye box 400 using only a first display unit, which helps reduce the structural complexity of the head-up display device 100. Furthermore, the first display unit can be, but is not limited to, configured as a liquid crystal display (LCD). However, this design is not limited to this; in some other embodiments, the head-up display device 100 includes multiple display units, and the information display is located in one of the multiple display units. The display unit can be, but is not limited to, configured as a liquid crystal display (LCD).

[0036] The shapes of the display area and the information display area 210 can vary. In some embodiments, the display area is rectangular, and the information display area 210 is also rectangular, with the length direction of the display area coinciding with the length direction of the information display area 210. However, this design is not limited to this; in some other embodiments, the display area is circular, and the information display area 210 is triangular.

[0037] In some embodiments, the head-up display device 100 includes a display device 200 and a reflector 300. The display device 200 emits light, and the reflector 300 reflects the light to the eye box 400. The information display area 210 can be located at different positions on the display device 200. It is understood that the reflector 300 can change the optical path of the information display area 210, making the placement of the head-up display device 100 in a vehicle more flexible. However, this design is not limited to this; in some other embodiments, the reflector 300 can be omitted to reduce the manufacturing cost of the head-up display device 100. It is worth noting that the display device 200 includes at least one display unit.

[0038] In some embodiments, the reflector 300 is fixed relative to the display device 200. That is, the reflector 300 is stationary relative to the display device 200.

[0039] This allows the head-up display device 100 to change the optical path of the information display area 210, and thus the position of the eye box 400, without the need for the mirror 300 to rotate. This helps reduce the noise emitted by the head-up display device 100 and greatly improves the user experience.

[0040] This allows the head-up display device 100 to eliminate the need for a transmission mechanism and drive components that change the relative position of the reflector 300 and the display device 200. Consequently, noise generated by the operation of these transmission mechanisms and drive components can be eliminated. This reduces the noise emitted by the head-up display device 100 and improves the user experience.

[0041] Furthermore, by eliminating the transmission mechanism and drive components that change the relative position of the reflector 300 and the display device 200, it is also beneficial to reduce the failure rate of the head-up display device 100.

[0042] However, this design is not limited to this. In some other embodiments, the reflector 300 includes a base, a mirror surface disposed on the base, and a first driving member and a first transmission mechanism disposed on the base. The first driving member drives the mirror surface to rotate relative to the base through the first transmission mechanism, thereby changing the relative position of the mirror surface and the display device 200. This makes the way the head-up display device 100 changes the optical path more flexible.

[0043] In some embodiments, the reflector 300 is configured as a concave mirror. Thus, the concave mirror can magnify the image in the information display area 210, which is beneficial for the user to obtain the information displayed in the information display area 210. However, this design is not limited to this; in some other embodiments, the reflector 300 is configured as a plane mirror.

[0044] In some embodiments, the number of reflectors 300 is one. This makes the structure of the head-up display device 100 more compact, which helps to reduce the manufacturing cost of the head-up display device 100. In addition, it also helps to reduce optical losses. However, this design is not limited to this; in some other embodiments, the number of reflectors 300 can be multiple.

[0045] Secondly, embodiments of this utility model provide a vehicle including the aforementioned head-up display device 100. This head-up display device 100 employs all the technical solutions of all the above embodiments, and therefore possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here. The vehicle can be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this disclosure does not specifically limit it in this regard.

[0046] In some embodiments, the vehicle includes a windshield 600, and light emitted from the head-up display 100 forms a virtual image 500 through the windshield 600 and is reflected by the windshield 600 to the eye box 400. The head-up display 100 is fixed relative to the windshield 600. This allows the vehicle to eliminate the need for a transmission mechanism and drive unit that alters the relative position of the head-up display 100 and the windshield 600. This eliminates noise generated by the operation of the transmission mechanism and drive unit, thus reducing vehicle noise and improving the user experience. Furthermore, eliminating the transmission mechanism and drive unit that alters the relative position of the windshield 600 and the head-up display 100 also helps reduce the failure rate of the head-up display 100. However, this design is not limited to this. In some other embodiments, the vehicle includes a body, a windshield 600 disposed on the body, a head-up display 100 disposed on the body, and a second drive member and a second transmission mechanism respectively disposed on the body. The second drive member drives the head-up display 100 to move relative to the windshield 600 through the second transmission mechanism, thereby changing the relative position of the head-up display 100 and the windshield 600, and thus changing the position of the eye box 400. This makes the way the vehicle changes the position of the eye box 400 more flexible. The second transmission mechanism can be connected to the reflector 300 in the head-up display 100 to drive the reflector 300 to move or rotate. The second transmission mechanism can also be connected to the display device 200 in the head-up display 100 to make the display device 200 move or rotate.

[0047] In some embodiments, the information display area 210 can be located at different positions of the head-up display device 100 along the height direction of the vehicle, and the information display area 210 at different positions is used to correspond to the eye box 400 at different positions along the height direction of the vehicle.

[0048] For example, in the vertical direction of the vehicle, the information display area 210 is located in the center of the display device 200. At this time, the light emitted by the display device 200 shines directly onto the concave mirror at a fixed emission angle. The light emitted from the information display area 210 illuminates the concave mirror, is reflected by the mirror surface onto the windshield, and then reflected again by the windshield 600, projecting the light emitted from the information display area 210 onto the eye box 400. When the human eye is positioned within the eye box 400, this light can be received. Furthermore, the light reflected by the reflector 300 also forms a virtual image 500 through the windshield 600. To accommodate drivers of shorter stature, the information display area 210 can be adjusted upwards along the vehicle's height, causing the eye box 400 to lower. To accommodate drivers of taller stature, the information display area 210 can be adjusted upwards along the vehicle's height, causing the eye box 400 to rise.

[0049] However, this design is not limited to this. In some other embodiments, the information display area 210 is located at different positions of the head-up display device 100 along the width direction of the vehicle. The information display area 210 at different positions corresponds to the eye box 400 at different positions along the width direction of the vehicle. This facilitates switching between the eye box 400 in the driver's cab and the passenger's cab, allowing the passenger in the passenger's cab to directly obtain the information displayed in the information display area 210. For example, in the vertical direction of the vehicle, the information display area 210 is located in the middle of the display device 200. At this time, the light emitted by the display device 200 shines directly onto the concave mirror at a fixed emission angle. The light emitted by the information display area 210 illuminates the concave mirror, is reflected by the surface of the concave mirror onto the windshield, and is then reflected by the windshield 600, emitting the light emitted by the information display area 210 to the eye box 400, where the human eye can receive the light when it is located in the eye box 400. Furthermore, the light reflected by the reflector 300 forms a virtual image 500 through the windshield 600. To allow the passenger in the front passenger seat to directly access the information displayed in the information display area 210, the information display area 210 can be adjusted to the right of the vehicle, assuming the passenger seat is to the right of the driver's seat, so that it is closer to the passenger seat, thus bringing the eyepiece 400 closer to the passenger seat. Similarly, to allow the driver in the front passenger seat to directly access the information displayed in the information display area 210, the information display area 210 can be adjusted to the left of the vehicle, so that it is closer to the driver's seat, thus bringing the eyepiece 400 closer to the driver's seat.
