[0044] One aspect of the present disclosure relates to a display device for a front windshield of vehicle, comprising: a projector unit movably arranged below the front windshield and comprising a display screen; and an adjusting unit connected to the projector unit and comprising an electric motor, wherein the display screen of the projector unit faces the front windshield, and an angle between the display screen and the front windshield is adjustable by means of the electric motor.
[0045] In head-up displays or other existing projection-type display devices according to the prior art, the angle of the screen used for information display cannot be adjusted, which creates inconvenience for people who are taller or lower in height, in which the driver has to raise or lower his head in order to find a clearer perspective. This undoubtedly poses a driving hazard. Unlike the prior art, the display device according to the present disclosure comprises an adjusting unit connected to the projector unit, the adjusting unit comprises an electric motor, which is capable of adjusting an angle of the projector unit by forward and reverse rotation of the electric motor, thereby changing the relative position between the display screen of the projector unit and the front windshield, so as to provide an optimal viewing angle for the driver. In addition, the display device is arranged below the front windshield. On the one hand, the mirrored image of the display screen of the display device on the front windshield is positioned down and close to the road ahead, so that the driver does not need to deviate much from his or her sight to see the information provided by the mirrored image. On the other hand, most front windshields provide a black edge at their lower edge, which provides a good background for the mirrored image, resulting in a clearer mirrored projection.
[0046] According to one or more embodiments of the present disclosure, by means of the electric motor the projector unit is capable of being driven to rotate around a rotation axis. The projector unit comprises a connecting flange fixedly connected to the display screen. The connecting flange is fixed to a side of the display screen back away from front windshield. Torque provided by the electric motor is transferred to the connecting flange through a transmission mechanism, so that a rotation of the connecting flange is realized by an operation of the electric motor.

[0047] According to one or more embodiments of the present disclosure, the transmission mechanism comprises at least a worm leading from the electric motor and a worm gear engaged with the worm, wherein the wear gear is torsion-proof connected to the connecting flange. A rotation shaft having the rotation axis is provided, wherein the rotation shaft is torsion-proof connected to the connecting flange and the worm gear. As a result, the adjustment of the angle between the display screen of the projector unit and the front windshield is realized in a simple manner.
[0048] According to one or more embodiments of the present disclosure, the rotation shaft comprises a non-circular cross-section and passes through the connecting flange and the worm gear. Thus, the rotation of the rotation shaft leads directly to the rotation of the connecting flange and the worm gear.
[0049] Another aspect of the present disclosure relates to a display assembly, comprising: a cover panel embedded in a center console below a front windshield; and at least a display device above-mentioned, wherein the display device is arranged underneath the cover panel.

[0050] Another aspect of the present disclosure relates to a display system, comprising: at least a display device above-mentioned; and a motor drive for the electric motor of the display device, wherein the motor drive is configured to receive a control signal comprising an information about rotation direction and / or a stroke of the electric motor, wherein the electric motor rotates in accordance with the control signal.
[0051] According to one or more embodiments of the present disclosure, the display system further comprising a processor configured to receive and process an input signal and thereby generate the control signal, wherein the control signal is transmitted to the motor drive.
[0052] According to one or more embodiments of the present disclosure, the display system further comprising a host computer interface configured to send the control signals to the motor drive or to send the input signal to the processor.
[0053] According to one or more embodiments of the present disclosure, driver information and control signal and / or input signal corresponding thereto is stored in the host computer interface, which is configured to automatically send the control signals and / or input signals corresponding to a driver when the driver is identified, thereby causing the motor drive to automatically adjust the operation of the electric motor.
[0054] According to one or more embodiments of the present disclosure, the input signal comprises a touch signal, optical signal and / or sound signal.
[0055] FIG. 1 schematically illustrates a display assembly for a vehicle according to the present disclosure; FIG. 2 schematically illustrates a front view of the display assembly shown in FIG. 1, and FIG. 3 schematically illustrates a partial rear view of the display assembly shown in FIG. 1.

Light emitted by the display device 100 can be incident on the front windshield 200 through the transparent cover plate 300. In this case, the area at the lower edge of the front windshield 200 functions as a mirror, by means of which the image provided by the display device 100 is mirrored in front of the lower edge of the front windshield 200. This mirror image is close to the road surface in front of the vehicle so that the driver does not have to divert his / her sight from the road in order to obtain the information. According to an embodiment, the lower edge of the front windshield 200 is provided with a black edge, which is more favorable for clear mirrored imaging.
[0059] As shown in FIGS. 7 and 8, the display device 100 comprises a projector unit 10 and an adjusting unit 20.
[0060] The projector unit 10 comprises a plate-shaped display screen 12 having a front surface toward the front windshield 200 to project an image on the front windshield 200. The adjusting unit 20 comprises an electric motor 22, a motor shaft with a worm 24 leading from the electric motor 22 and a worm gear 26 engaged with the worm gear 26 having a center bore 26a. In order to connect the adjustment unit 20 to the display screen 12, a pair of mutually opposed connecting flanges 16 having connecting holes 16a are fixedly connected at the back of the display screen 12. A rotation shaft 28 having a rotation axis 28a extends through the connection holes 16a of the connecting flanges 16 and the center bore 26a of the worm gear 26, thereby arranging the worm gear 26 between these two connecting flanges 16. In an embodiment not shown, the connecting flange 16 may also be provided on the side of this display screen 12. In order to realize power transmission from the adjustment unit 20 to the projector unit 10, the rotation shaft 28 comprises a non-circular cross-section, and may for example comprise a circular notched cross-section as shown. Of course, in embodiments not shown, the rotation shaft 28 may comprise a polygonal or elliptical cross-section, for example having a rectangular, square or triangular cross-section. Accordingly, the connecting hole 16a of the connecting flange 16 and the center hole 26a of the worm gear 26 have corresponding shapes, and the rotation shaft 28 is shape-fitly embedded in the connecting hole 16a and center hole 26a. When the motor shaft rotates, the worm gear 24 rotates the worm gear 26 and rotates the connecting flange 16 as well as the display screen 12 around the rotation axis 28a. Thus, torque provided by the electric motor 22 can transmit to the display screen 12.
[0061] FIG. 9A to FIG. 9C show side views of the display device 100 in different states.
[0062] In FIG. 9A the front windshield 200 is schematically shown, below which the display device 100 is arranged in an initial position.
