[0023] The following specific implementation methods will further illustrate the present application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0024] The embodiment of the present application provides a vehicle-mounted display system and a vehicle including the vehicle-mounted display system. The vehicle-mounted display system can project images at different positions of the vehicle through translation and / or rotational movement and modulation of the image light projection direction. Compared with the traditional liquid crystal display hard screen, the vehicle-mounted display system and vehicle of the embodiment of the present application have more flexible and convenient display positions, and can achieve high-definition display of various complex surfaces in the vehicle. In addition, the vehicle-mounted display system of the embodiment of the present application can also realize human-computer interaction based on the touch function, and realize multi-module linkage based on the signal feedback of the sensor.

[0025] See also Figure 1 The vehicle 1 of the embodiment of the present application includes a vehicle body 10 and a vehicle display system 20. The vehicle body 10 forms a vehicle space 11, and the vehicle display system 20 is located in the vehicle space 11 and connected to the vehicle body 10. The vehicle display system 20 is used to project image light to different positions in the vehicle space 11 to display a projected image.

[0026] In this embodiment, the vehicle 1 is a commercial vehicle with three rows of seats. Figure 1 and Figure 2 The vehicle body 10 includes a frame structure 12 and a side window 13 embedded in the frame structure 12. The vehicle 1 also includes a front projection screen 31, a rear projection screen 32, a cockpit seat 41, a second row of seats 42, a rear row of seats 43 and a table 50 located in the vehicle space 11. The front projection screen 31 and the rear projection screen 32 are respectively fixedly connected to the ceiling of the frame structure 12, wherein the front projection screen 31 is located between the cockpit seat 41 and the second row of seats 42, and the rear projection screen 32 is located between the rear row of seats 43 and the rear windshield of the vehicle (not shown). The vehicle display system 20 is connected to the ceiling of the frame structure 12 and is located between the front projection screen 31 and the rear projection screen 32. The table 50 is located at the second row of seats 42.

[0027] The straight line direction from the rear windshield of the vehicle to the front of the vehicle (that is, the direction of travel of the vehicle) is defined as the translation direction L1. In this embodiment, the vehicle-mounted display system 20 can be translated relative to the vehicle body 10 along the translation direction L1, and can be rotated around an axis L2 perpendicular to the ground where the vehicle 1 is located. The direction of the image light emitted by the vehicle-mounted display system 20 is adjustable, thereby realizing the display of the projection image on at least the front projection screen 31, the rear projection screen 32, the side window 13 and the table 50.

[0028] In this embodiment, the side window 13 is a color-changing glass that can directly display the projected image. The front projection screen 31 and the rear projection screen 32 can be rolled up when idle, and unfolded to display the projected image when in use. In this embodiment, the rear seats 43 are foldable. When the vehicle-mounted display system 20 projects image light onto the rear projection screen 32 to display an image, the rear seats 43 can be folded to prevent the rear seats 43 from affecting the propagation of the image light.

[0029] See also Figure 3 In this embodiment, the second row of seats 42 can rotate and translate relative to the vehicle body 10, so that users on the second row of seats 42 can approach and face the table 50. Therefore, when a projected image is displayed on the surface of the table 50, users on the second row of seats 42 and the rear row of seats 43 can observe the projected image on the table 50 together, which is particularly suitable for scenes such as meetings and entertainment.

[0030] For the vehicle-mounted display system 20 of the embodiment of the present application, Figure 2 and Figure 3 The projection positions are shown in the figure as examples only, but are not limited to Figure 2 and Figure 3 For example, in other embodiments of the present application, the vehicle 1 may further include other projection screens in addition to the front projection screen 31 and the rear projection screen 32. For example, in other embodiments of the present application, the direct light machine 21 may also display projection images on the armrests and backrests of each seat (cockpit seat 41, second row seat 42, rear row seat 43), etc.

[0031] See also Figure 4 In this embodiment, the table 50 can be used to display the projected image and also to realize the touch function. The table 50 of this embodiment includes a table body 51, a touch film 52 and a covering layer 53. The table body 51, as the main structure of the table 50, includes a long strip of supporting legs 511 and a table top 512 connected to one end of the supporting legs 511 and perpendicular to the supporting legs 511. The touch film 52 is arranged on the surface of the table top 512 away from the supporting legs 511. The covering layer 53 covers the side surfaces of the touch film 52 and the table top 512, which is used to protect the touch film 52 and play an aesthetic role.

[0032] In this embodiment, the touch film 52 is a pressure touch film (for example, including a pressure-sensitive material layer and array electrodes respectively located on both sides of the pressure-sensitive side material layer). When the user applies a pressure greater than a pressure threshold on the surface of the coating layer 53 (for example, a touch operation), the touch film 52 senses the pressure and generates a touch sensing signal. The table 50 also includes a signal line (not shown) electrically connected to the touch film 52 at one end and electrically connected to the vehicle display system 20 at the other end. The vehicle display system 20 can identify the touch coordinates of the user on the table 50 based on the touch sensing signal transmitted back by the signal line. The vehicle display system 20 can be used to display the corresponding projected image based on the identified coordinates. Therefore, based on the table 50 with integrated touch function, users in the vehicle space 11 can play chess and card games, edit documents, and can also enter the central control interface to adjust the temperature in the car, the position of tables and chairs, open and close windows, etc.

[0033] See also Figure 5 The vehicle display system 20 of this embodiment includes a direct light projector 21, a motion device 22 and a dimming device 23. The motion device 22 is connected to the frame structure 12 (see 10 and 12) of the vehicle body 10. Figure 2 ), the direct light machine 21 is movably connected to the side of the moving device 22 away from the vehicle body 10. The dimming device 23 is fixed on the direct light machine 21.

[0034] The direct light projector 21 has a light outlet 211 for emitting image light. The motion device 22 is used to drive the direct light projector 21 to translate and rotate relative to the vehicle body 10. The dimming device 23 is located in front of the light outlet 211 and is used to modulate the emission direction of the image light.

[0035] In this embodiment, the motion device 22 includes a guide rail 221 and a turntable 222. The guide rail 221 is fixedly connected to the ceiling of the vehicle body 10, the turntable 222 is slidably connected to the guide rail 221, and the direct light machine 21 is connected to a side of the turntable 222 away from the guide rail 221.

[0036] In this embodiment, the guide rail 221 is a long strip structure, which forms a track (not shown) extending along the translation direction L1, and the guide rail 221 is located between the front projection screen 31 and the rear projection screen 32. The turntable 222 is engaged in the track and can slide and translate in the track along the extension direction of the track. When the turntable 222 translates in the track, it synchronously drives the direct light machine 21 to translate along the extension direction of the track.

[0037] The turntable 222 is used to drive the direct projection light machine 21 to rotate around the axis L2. That is, the rotation plane when the turntable 222 drives the direct projection light machine 21 to rotate is parallel to the ground where the vehicle 1 is located. In this embodiment, the turntable 222 can drive the direct projection light machine 21 to rotate within an angle range of 0-180°, so that the direction of the image light projected by the direct projection light machine 21 can be adjusted within an angle range from toward the front of the vehicle to toward the rear of the vehicle. In at least one embodiment of the present application, the turntable 222 can drive the direct projection light machine 21 to rotate within an angle range of 0-360°.

[0038] The direct projector 21 includes a housing 212, and a light outlet 211 is provided on the housing 212. The dimming device 23 is connected to the housing 212 of the direct projector 21. The dimming device 23 includes a driving member 231 and a reflector 232 connected to the driving member 231. The driving member 231 is fixedly connected to the housing 212 of the direct projector 21. The reflector 232 is located in front of the light outlet 211 of the direct projector 21, and the surface of the reflector 232 facing the light outlet 211 is used to reflect the received image light. The driving member 231 is used to drive the reflector 232 to rotate around the axis L3 to change the angle state of the reflector 232. The axis L3 is perpendicular to the translation direction L1 and the axis L2, respectively.

[0039] The reflector 232 reflects the image light at different angles when in different angle states. Therefore, in this embodiment, the reflector 232 is driven to rotate by the driving member 231 to adjust the propagation direction of the image light after it is emitted from the light outlet 211, thereby guiding the image light to different positions in the vehicle 1 to display the projected image.

[0040] The reflector 232 has an initial angle state and a maximum rotation angle state, and in this embodiment, the angle difference between the initial angle state and the maximum rotation angle state is 90°, that is, the driving member 231 can drive the reflector 232 to rotate within an angle range of 0-90°. When the reflector 232 is in the initial angle state, it is moved out of the optical path of the image light, and the image light emitted from the direct light projector 21 is directly emitted from the light outlet 211 along the original path without passing through the reflector 232, and is projected to the corresponding position of the vehicle 1 to display the projection image. When the reflector 232 is in the maximum rotation angle state, it is introduced into the optical path of the image light, and the image light emitted from the direct light projector 21 can be reflected by the reflector 232 to the table 50 (see Figure 3 When the rotation angle of the reflector 232 is between 45° and 90°, the reflector 232 can reflect the image light to the seat armrest, seat back and other positions.

[0041] Please also read Figure 5 and Figure 6In this embodiment, the vehicle-mounted display system 20 further includes a control device 24, two angle sensors 25 and a displacement sensor 26. The motion device 22 further includes a translation driver 223 for driving the direct projection light machine 21 to translate and a rotation driver 224 for driving the direct projection light machine 21 to rotate. The translation driver 223, the rotation driver 224 and the driving member 231 are, for example, motors. The two angle sensors 25 are respectively connected to the turntable 222 and the reflector 232. The displacement sensor 26 is connected to the guide rail 221. The control device 24 is electrically connected to the direct projection light machine 21, the translation driver 223, the rotation driver 224, the two angle sensors 25 and the displacement sensor 26.

[0042] The control device 24 pre-stores multiple sets of position parameters. When the control device 24 outputs control signals to the translation driver 223, the rotation driver 224 and the driving member 231 based on different sets of position parameters, the translation driver 223 and the rotation driver 224 jointly drive the direct projection light machine 21 to translate and / or rotate so that the image light is projected to different positions in the vehicle. That is, each set of position parameters corresponds to a specific workstation of the direct projection light machine 21. When the current position parameters of the direct projection light machine 21 are consistent with a certain set of pre-stored position parameters, it indicates that the direct projection light machine 21 is now located at the workstation corresponding to the pre-stored set of position parameters. Among them, for any two different workstations, at least one of the parameters of the displacement of the direct projection light machine 21 along the translation direction L1, the rotation angle of the direct projection light machine 21 around the axis L2, and the rotation angle of the reflector 232 around the axis L3 is different.

[0043] The two angle sensors 25 are used to detect the rotation angles of the turntable 222 and the reflector 232, respectively, and the displacement sensor 26 is used to detect the displacement of the direct light machine 21 along the guide rail 221. When the direct light machine 21 is expected to be moved to a preset position, the control device 24 can be used to compare whether the rotation angles fed back by the two angle sensors 25 and the displacement fed back by the displacement sensor 26 are consistent with a set of preset position parameters corresponding to the preset position. If the rotation angle and the displacement are consistent with the preset set of position parameters, it indicates that the direct light machine 21 has moved to the preset position at this time, and the control device 24 controls the translation driver 223, the rotation driver 224 and the driving member 231 to stop driving. If the rotation angle and the displacement are consistent with the preset set of position parameters, the control device 24 continues to control the translation driver 223, the rotation driver 224 and the driving member 231 to drive.

[0044] The touch film 52 of the table 50 is electrically connected to the direct light projector 21 through a signal line, for example, a high definition multimedia interface (HDMI) of the direct light projector 21, thereby establishing a connection with the control device 24. The table 50 is used to transmit the touch sensing signal generated when the user performs a touch operation on the surface of the table 50 to the control device 24 in real time. The control device 24 is used to control the direct light projector 21 to display a corresponding image according to the touch sensing signal from the table 50.

[0045] In this embodiment, the direct projection light machine 21 also includes a projection lens (not shown) with variable focus, which is used to modulate the light from the light source to emit image light. Based on the zoom process, the size of the projected image at different projection distances can also be adjusted. The projection lens with variable focus may, for example, include a drive structure for adjusting the distance between optical lenses, and the control device 24 may be connected to the drive structure to control the working process of the drive structure to adjust the focal length of the projection lens. The control device 24 controls the focusing process of the projection lens so that the process of switching between different workstations of the direct projection light machine 21 is linked with the focusing process of the projection lens, thereby jointly realizing the display of a projection image of a specific size at a specific position of the vehicle.

[0046] In the embodiment of the present application, the control device 24 is a control circuit (or control chip) built into the housing 212 of the direct light machine 21. In at least one embodiment of the present application, the control device 24 may be a body control module (BCM) of the vehicle 1.

[0047] The vehicle-mounted display system 20 of the embodiment of the present application is applied in a vehicle 1. The vehicle-mounted display system 20 includes a motion device 22, and the motion device 22 includes a guide rail 221 and a turntable 222. The control device 24 drives the direct light machine 21 to translate along the translation direction L1 in the track of the guide rail 221 and rotate around the axis L2 by controlling the turntable 222, so that the direct light machine 21 can be switched to different workstations. The vehicle-mounted display system 20 also includes a dimming device 23, and the dimming device 23 includes a driving member 231 and a reflector 232. The control device 24 drives the reflector 232 to rotate around the axis L3 by controlling the driving member 231, and the image light from the light outlet 211 of the direct light machine 21 can be reflected at different angles through the reflector 232. That is, the dimming device 23 is controlled by the control device 24 to adjust the projection angle of the image light. In the embodiment of the present application, by switching the position of the direct projection light machine 21 and adjusting the projection angle of the image light, the image light can be projected to multiple different positions in the vehicle 1 (including but not limited to the front projection screen 31, the rear projection screen 32, the side window 13, the table 50, the seat armrest and the seat back, etc.) to display the projected image. Compared with the traditional LCD hard screen, the vehicle display system 20 and the vehicle 1 of the embodiment of the present application are more flexible and convenient in adjusting the display position of the projected image, and can achieve high-definition display of various complex surfaces in the vehicle.

[0048] In the embodiment of the present application, the direct projection light machine 21 also includes a zoom projection lens. The control device 24 controls the direct projection light machine 21 to translate along the translation direction L1 and coordinates the focusing of the projection lens to enable the direct projection light machine 21 to display a projection image of a specific size at a specific distance.

[0049] In the embodiment of the present application, the table 50 in the vehicle 1 is also integrated with a touch function based on pressure sensing (including a touch film 52). The control device 24 receives the touch sensing signal sent back by the touch film 52 through the direct projection light machine 21, and can identify the current touch coordinates of the user according to the touch sensing signal, and then control the direct projection light machine 21 to display the corresponding projection image according to the touch coordinates, which can facilitate human-computer interaction.

[0050] In the embodiment of the present application, the vehicle-mounted display system 20 also includes two angle sensors 25 and a displacement sensor 26, and the motion device 22 also includes a translation driver 223 and a rotation driver 224. The two angle sensors 25 are respectively used to detect in real time the rotation angle of the direct projection light machine 21 around the axis L2 and the rotation angle of the reflector 232 around the axis L3. The displacement sensor 26 is used to detect in real time the translation distance of the direct projection light machine 21 along the translation direction L1. Based on the rotation angle and displacement amount fed back by the two angle sensors 25 and the displacement sensor 26, the control device 24 feedback controls the driving process of the translation driver 223, the rotation driver 224 and the driving member 231, so as to move the direct projection light machine 21 to a preset position and emit the image light at a specific angle.

[0051] Furthermore, the control device 24 can pre-store multiple sets of position parameters corresponding to different workstations, and based on the rotation angle and displacement sent back by the two angle sensors 25 and the displacement sensor 26, it can realize one-click operation of the direct light machine 21 to the preset workstation.
