These light rays entering the eyes of the driver make it possible for the driver to see a virtual image of the picture displayed on the HUD image source, which appears on the other side of the transparent imaging window. Meanwhile, because the imaging window is transparent, the ambient light on the other side of the imaging window can still be transmitted into the eyes of the driver through the imaging window, so that the driver can see the HUD imaging and can observe the road condition outside the vehicle in the driving process without influencing the driver.

Under the condition that a driver drives normally, the actual road condition observed by the driver through the transparent imaging window is three-dimensional, while a virtual image formed by the traditional HUD is two-dimensional, and the two-dimensional virtual image cannot be attached to the three-dimensional actual road condition for display, so that the visual experience of the driver is reduced; simultaneously, because the formation of image distance of virtual image is generally not adjustable, and the position of driver's eyes focus then can come from going to adjust according to driver's self demand, this is just so that the formation of image position of the virtual image on the windshield is often inconsistent with the position of driver's eyes focus, like this, when the driver need carefully watch the virtual image, then need adjust the position of self eyes focus constantly to unanimous with the virtual image, thereby can lead to producing the vergence conflict of vision, make the driver easily produce bad health such as tired, nausea.

At present, the HUD technique can become the driver and look at the distraction that the panel board leads to at the in-process of driving the motor vehicle head-down, improves and drives factor of safety, also can bring better driving simultaneously and experience, consequently, uses car windshield to carry out the HUD that images and is receiving more and more attention.

The HUD is an optical system designed through internal characteristics, some driving information is reasonably and vividly displayed in a driver sight line area, under the condition that a driver normally drives, the actual road condition observed by the driver through a transparent imaging window is three-dimensional, a virtual image formed by the traditional HUD is two-dimensional, the two-dimensional virtual image cannot be attached to the three-dimensional actual road condition for display, and the visual experience of the driver is reduced; simultaneously, because the formation of image distance of virtual image is generally not adjustable, and the position of driver's eyes focus then can come from going to adjust according to driver's self demand, this is inconsistent often with the position of driver's eyes focus just so that the formation of image position of the image on the windshield, like this, when the driver need carefully watch the virtual image, then need adjust the position of self eyes focus constantly to unanimous with the virtual image, thereby can lead to producing vergence conflict, make the driver easily produce bad health such as tired, nausea.

In order to solve the above technical problem, an embodiment of the present invention proposes a head-up display device, which includes a stereoscopic image source 100 and a reflection unit, as shown in fig. 1.

The head-up display device may be mounted on various vehicles, such as automobiles, trains, airplanes, mail ships, etc., and in this embodiment, the head-up display device is mounted on an automobile as an example.

Specifically, in the example of fig. 1, the head-up display device further includes a housing 400, the housing 400 is provided with a light outlet 401, in an actual application scenario, the stereoscopic image source 100 and the reflection unit are both disposed in the housing 400, the stereoscopic image source 100 is configured to emit light rays capable of forming a stereoscopic image, the light rays emitted via the stereoscopic image source 100 are reflected by the reflection unit, and the reflected light rays are emitted through the light outlet 401, so that the emitted light rays are reflected by the external imaging device 500 to form the virtual image 107.

In this embodiment, by setting the stereoscopic image source 100, light rays forming a stereoscopic image can be emitted, and since objects of the stereoscopic image and an actual environment are three-dimensional images, the stereoscopic image and the actual environment are more easily fused, and experience of an observer for observing the stereoscopic image is improved.

In order to adjust the imaging distance of the virtual image 107, the imaging position of the virtual image 107 is made to coincide with the position where the eyes of the driver are focused, and therefore, in the present embodiment, the head-up display device further includes a moving device (not shown in the figure) for moving the reflection unit so that the imaging position of the virtual image 107 is changed.

Optionally, the moving device may include a motor, a gear and a rack, and in an actual installation process, the reflecting unit may be fixed to the rack, an output shaft of the motor is rotatably connected to the gear, and the gear is further engaged with the teeth, so that when the motor drives the gear to rotate, the rack may drive the reflecting unit to move, and thus an imaging position of the virtual image 107 is changed.

Optionally, the moving device may include a cylinder, a sliding rail, and a sliding block, and in an actual installation process, the reflecting unit may be fixed to the sliding block, the sliding block is connected to the sliding rail in a sliding manner, and an output end of the cylinder is fixed to the sliding block, so that when the cylinder drives the sliding block to slide on the sliding rail, the sliding block may drive the reflecting unit to move, and thus an imaging position of the virtual image 107 is changed.

Based on the above, by moving the reflection unit, the distance between the reflection unit and the light emitted from the stereoscopic image source 100 can be changed accordingly, according to the principle of imaging, the imaging distance of the virtual image 107 and the distance between the light emitted from the stereoscopic image source 100 and the reflection unit are in a direct proportion, therefore, by moving the reflection unit, the distance between the reflection unit and the light emitted from the stereoscopic image source 100 can be changed, so that the imaging position of the virtual image 107 can be changed according to the position focused by the eyes of the driver, the imaging position of the virtual image 107 is ensured to be the same as the position focused by the eyes of the driver, the occurrence of vergence conflict is avoided, the occurrence of bad conditions such as fatigue and nausea of the driver is prevented, and the driving safety is improved.

As can be seen from the above, the stereoscopic image source 100 in the present embodiment is configured to emit light rays capable of forming a stereoscopic image, the reflection unit is configured to reflect the light rays, and the reflected light rays are emitted through the light outlet 401 and further reflected by the external imaging device 500 to form the virtual image 107.

The curved mirror 202 may be embodied as a concave mirror, and the concave mirror may converge the light emitted from the stereoscopic image source 100 to form the virtual image 107.

From the imaging properties of the curved mirror 202, it can be seen that: the image distance of the virtual image 107 formed by the light rays is increased along with the increase of the optical distance between the stereoscopic image source 100 and the curved reflector 202, that is, the larger the optical distance between the stereoscopic image source 100 and the curved reflector 202 is, the larger the distance between the driver and the image imaged by the curved reflector 202 viewed by the driver is, therefore, the reflecting unit may further include a plane reflector 201, and by arranging the corresponding plane reflector 201 between the stereoscopic image source 100 and the curved reflector 202, the light rays are increased by the corresponding reflection times, the propagation path of the light rays is increased, so that the optical distance between the stereoscopic image source 100 and the curved reflector 202 is increased, and the distance between the driver and the image imaged by the curved reflector 202 viewed by the driver is increased.

The curved mirror 202 can amplify an image and provide a longer imaging distance, and can also compensate for image distortion caused by the external imaging device 500, for example, when the external imaging device 500 is a curved surface type, light reflected by the external imaging device 500 can cause image distortion, the surface type design of the curved mirror 202 can counteract the distortion, and the planar mirror 201 can improve the space utilization rate and compress the volume of the head-up display device.

Further, the moving device may drive the plane mirror 201 to move along any one direction within an included angle formed by a reflection main axis of the plane mirror 201 and an incidence main axis, so that an imaging position of the virtual image is changed.

Preferably, referring to fig. 1, the moving device drives the plane mirror 201 to move along the normal direction of the light ray emitted from the stereoscopic image source 100 incident to the reflection unit, so that the imaging position of the virtual image 107 is changed, wherein the dotted line portion in fig. 1 represents the normal direction.

Illustratively, two virtual images 107 at positions a and B formed by the reflection unit before and after the movement are shown in fig. 1.

In some optional implementations of the present embodiment, the stereoscopic image source 100 includes: the stereoscopic image display device comprises a light source 101, a backlight module 102, an image generating element 103 and a stereoscopic conversion element, wherein the light source 101 is used for emitting light rays, the backlight module 102 is used for transmitting the light rays emitted by the light source 101, the image generating element 103 is used for converting the light rays transmitted by the backlight module 102 into image light rays, and the stereoscopic conversion element is used for converting the image light rays into light rays capable of forming a stereoscopic image.

Specifically, the Light source 101 is mainly used for Emitting Light, and the Light source 101 may include at least one electroluminescent element, which is excited by an electric Field to generate Light, such as a Light Emitting Diode (LED), an Organic Light-Emitting Diode (OLED), a Mini LED (Mini LED), a Micro LED (Micro LED), a Cold Cathode Fluorescent Lamp (CCFL), an LED Cold Light source 101211(Cold LED Light, CLL), an Electro Luminescence (EL), an electron Emission (Field Emission Display, FED), or a Quantum Dot Light source 101211(Quantum Dot, QD).

The light source 101 may include at least one of R (red)/G (green)/B (blue) monochromatic light sources 101, the light emitted after being turned on is transmitted through the backlight module 102 and then passes through the image generating element 103 to form corresponding image light, and if color display is to be implemented, the light source 101 may include R/G/B three-color light sources 101 at the same time, the R/G/B three-color light sources 101 are respectively turned on in a time-sequential manner, and the light emitted from the three-color light sources 101 is transmitted by the backlight module 102 and then passes through the image generating element 103 to form corresponding monochromatic images; since the time of the light emission interval between the three light sources 101 is short, human eyes cannot distinguish them according to the principle of persistence of vision, and the three monochromatic images incident to human eyes can be superimposed into a color image.

Further, as shown in fig. 2, the backlight module 102 includes a light guide element 1021, a direction control element 1022, and a diffusion element 1023, wherein the light guide element 1021 is used for transmitting the light emitted from the light source 101, the direction control element 1022 is used for converging the light transmitted through the light guide element 1021, and the diffusion element 1023 is used for diffusing the light converged through the direction control element 1022.
