[0068] Reference Figures 1 to 15 , shows a structural schematic diagram of a display screen device described in an embodiment of the present application and its application to an instrument panel, the instrument panel has an instrument panel 600, and the display screen device includes: a display mechanism 100, a position adjustment mechanism 200 and a driving mechanism 300; the position adjustment mechanism 200 is used to connect the instrument panel, the display mechanism 100 is movably connected to the position adjustment mechanism 200, and the driving mechanism 300 is connected to the display mechanism 100; the driving mechanism 300 drives the display mechanism 100 to move along the position adjustment mechanism 200, so that the display mechanism 100 moves between a use position and a storage position, in which the display mechanism 100 is at least partially exposed on the instrument panel 600 in the use position, and is stored in the instrument panel 600 in the storage position.

[0069] In the embodiments of this application, Figure 7 , a schematic diagram of the display mechanism 100 in the use position, the storage position, and the intermediate position is shown. When the display mechanism 100 needs to be used, the driving mechanism 300 can drive the display mechanism 100 to move along one end of the position adjustment mechanism 200 to the other end, so that the display mechanism 100 is at least partially exposed outside the instrument panel 600. Figure 2 As shown, the user can use the exposed display mechanism 100. When the display mechanism 100 is not needed, the driving mechanism 300 can reversely drive the display mechanism 100 to move along the other end of the position adjustment mechanism 200 to one end, and the display mechanism 100 is not exposed but stored in the instrument panel 600, as shown in FIG. Figure 3As shown, the risk of the user accidentally touching the display mechanism 100 is reduced, reducing damage to the display mechanism 100 and reducing the risk of bumps and injuries to the user, thereby improving the safety of the display screen device. In this way, the display mechanism 100 can be switched between the use position and the storage position. In addition, the display mechanism 100 can be located in any position between the use position and the storage position, and can be set according to user needs. The embodiment of the present application does not limit the specific position where the display mechanism 100 moves to on the position adjustment mechanism 200.

[0070] For example, in an embodiment of the present application, the position adjustment mechanism 200 can be disposed below the instrument panel 600, and the position adjustment mechanism 200 is tilted, having one end close to the instrument panel 600 and the other end away from the instrument panel 600. In the use position, the drive mechanism 300 drives the display mechanism 100 to move to the end of the position adjustment mechanism 200 close to the instrument panel 600, so that the distance between the display mechanism 100 and the instrument panel is relatively close, and at least a portion of the display mechanism 100 is exposed on the instrument panel 600. In the storage position, the drive mechanism 300 drives the display mechanism 100 to move to the end of the position adjustment mechanism 200 away from the instrument panel 600, so that the distance between the display mechanism 100 and the instrument panel is relatively far, so that the display mechanism 100 is stored below the instrument panel 600.

[0071] Optionally, in the embodiment of the present application, the display mechanism 100 can be rotatably connected to the position adjustment mechanism 200 in the use position to adjust the display angle of the display mechanism 100. In this way, the display mechanism 100 can be rotated relative to the position adjustment mechanism 200 to adjust the display angle of the display mechanism 100 to a more suitable angle for user viewing, according to the needs of different users. This avoids the problem of the existing art in which the fixed display mechanism 100 cannot be adjusted and is difficult to accommodate different users' viewing angles.

[0072] For example, in the embodiments of the present application, Figure 4 As shown, the left side is an illustration of the user's perspective. In the use position, the adjustment angle of the display mechanism 100 can be between angle a and angle b, and the difference between angle a and angle b can be 25°, 20° or 30°, etc., that is, the adjustment range of the display mechanism 100 can be 25°, 20° or 30°, etc. The adjustment range can be set according to actual needs, and the embodiment of the present application may not limit the adjustment range of the display mechanism 100.

[0073] In the embodiment of the present application, the position adjustment mechanism 200 optionally includes a slide rail 210 and a connecting plate 220 connected to the slide rail 210, with a slide groove 211 provided on the slide rail 210. The display screen device further includes a movable assembly 400, which is connected to the display mechanism 100 and movably connected to the slide groove 211. The driving assembly drives the movable assembly 400 to move along the slide groove 211, thereby moving the display mechanism 100 along the position adjustment mechanism 200. In this way, the movement trajectory of the display mechanism 100 can be designed by the shape of the slide groove 211, and the movable connection between the display mechanism 100 and the position adjustment mechanism 200 can be achieved through the movable assembly 400. Specifically, the movable component 400 can rotate in the slide groove 211 and move along the slide groove 211 at the same time, so that there is rolling friction between the movable component 400 and the slide groove 211, which has smaller friction resistance, reduces transmission loss, improves transmission efficiency, reduces friction loss between the movable component 400 and the slide rail 210, reduces noise and vibration, improves operation smoothness, and also reduces energy consumption of the driving component.

[0074] Optionally, in an embodiment of the present application, the slide groove 211 includes a linear groove and a curved groove that are interconnected. The movable component 400 drives the display mechanism 100 to perform linear motion along the linear groove, and the movable component 400 drives the display mechanism 100 to perform rotational motion along the curved groove. In this way, the display mechanism 100 can adjust its position within a large range through the movement of the movable component 400 along the linear groove, and the display mechanism 100 can adjust the orientation of the display screen 110 of the display mechanism 100 through the movement of the movable component 400 along the curved groove, for example, rotating the display screen 110 facing downward to face forward or upward. And through the rotational motion of the display mechanism 100 along the curved groove, the display angle of the display mechanism 100 is adjusted to the optimal viewing angle suitable for the user.

[0075] For example, in the embodiment of the present application, the rotation angle of the display mechanism 100 can be designed by designing the curvature of the curved groove, which can be set according to actual needs. The embodiment of the present application does not limit the specific setting method of the curvature of the curved groove.

[0076] Optionally, in the embodiment of the present application, the slide groove 211 includes a first slide groove 212 and a second slide groove 213, and the first slide groove 212 is arranged parallel to the second slide groove 213; the movable assembly 400 includes a first movable member 410 and a second movable member 420 arranged at intervals, the first movable member 410 is connected to the display mechanism 100, and the first movable member 410 is movably connected to the first slide groove 212, and the second movable member 420 is connected to the display mechanism 100, and the second movable member 420 is movably connected to the second slide groove 213. In this way, the first movable member 410 and the second movable member 420 are arranged at intervals and move within the first slide groove 212 and the second slide groove 213 respectively, so that the two connection points with a certain distance between them can achieve a better restraining effect on the display mechanism 100, thereby ensuring that the display mechanism 100 has better movement stability and reliability along the slide groove 211 of the slide rail 210.

[0077] Optionally, in the embodiment of the present application, the movable assembly 400 includes a fastener 430 and a sleeve 440 sleeved on the fastener 430; the fastener 430 and the sleeve 440 are inserted into the slide groove 211, and the fastener 430 is connected to the display mechanism 100. When the display mechanism 100 moves along the position adjustment mechanism 200, the sleeve 440 and the slide groove 211 are subjected to rolling friction. In this way, the fastener 430 realizes the connection between the movable assembly 400 and the display mechanism 100, and the sleeve 440 realizes the rotation and movement between the movable assembly 400 and the slide groove 211. In addition, the sleeve 440 and the slide groove 211 are subjected to rolling friction, which has a small friction resistance, reduces transmission loss, improves transmission efficiency, reduces friction loss between the sleeve 440 and the slide rail 210, reduces noise and vibration, improves operation smoothness, and also reduces energy consumption of the drive assembly.

[0078] For example, in the embodiment of the present application, the fastener 430 may be a screw, a bolt, or a stud, etc., and may be configured according to actual production needs. The embodiment of the present application does not limit the type of the fastener 430.

[0079] In the embodiment of the present application, optionally, the number of the slide rails 210 includes two, and the two slide rails 210 are respectively connected to the two ends of the connecting plate 220; the two slide rails 210 and the connecting plate 220 enclose a receiving cavity, and part of the display mechanism 100 is arranged in the receiving cavity, and a avoidance opening 230 is formed between the connecting plate 220 and the slide rails 210. In this way, other structures on or near the dashboard in the vehicle, such as air conditioners, are avoided through the avoidance opening 230, meeting the vehicle mounting requirements and avoiding interference between the display screen device and other structures. And part of the display mechanism 100 is arranged in the receiving cavity. Specifically, the mounting plate 120 of the display mechanism 100 can be arranged in the receiving cavity, reducing the space required to be occupied by the display mechanism 100, improving space utilization, and facilitating the structural layout of the vehicle interior space.

[0080] For example, the number of connecting plates 220 can be two, and the two connecting plates 220 are spaced apart at the two ends of the two slide rails 210. The two connecting plates 220 and the two slide rails 210 form a rectangular or quasi-rectangular avoidance opening 230. In addition, the shape of the avoidance opening 230 can also be a trapezoid or a trapezoid, etc., and the number of connecting plates 220 can also be three or four, etc., which can be set according to actual conditions. The embodiment of the present application does not limit the specific formation method and shape type of the avoidance opening 230.

[0081] Optionally, in the embodiment of the present application, the drive mechanism 300 includes a driver 310 and a transmission structure connected to the driver 310. The transmission structure is connected to the display mechanism 100. The driver 310 activates the transmission structure, which drives the display mechanism 100 to move along the position adjustment mechanism 200. In this way, the driver 310 provides a relatively stable and reliable power source for the transmission structure, which transmits force through the transmission structure and drives the display mechanism 100 to move on the position adjustment mechanism 200.

[0082] In the embodiment of the present application, for example, when the display mechanism 100 is moved from the storage position to the use position, the driver 310 drives the transmission structure to move the display mechanism 100 to one end of the slide slot 211. At this time, the movable assembly 400 abuts against one end of the slide slot 211, and the driver 310 stops operating. When it is necessary to move the display mechanism 100 from the use position to the storage position, the driver 310 rotates in the opposite direction, driving the transmission structure to move the display mechanism 100 in the opposite direction to the other end of the slide slot 211. At this time, the movable assembly 400 abuts against the other end of the slide slot 211, and the driver 310 stops operating.

[0083] For example, in the embodiment of the present application, the driver 310 may be an electric motor or the like, and may be configured according to actual power requirements. The embodiment of the present application does not limit the specific type of the driver 310.

[0084] Optionally, in an embodiment of the present application, the transmission structure includes a worm gear assembly and a screw nut assembly, wherein the worm gear assembly is connected to the driver 310, and the screw nut assembly is connected to the display mechanism 100. In this way, two-stage transmission can be achieved through the worm gear assembly and the screw nut assembly, thereby reducing the torque transmitted to the display mechanism 100 by the screw nut 360, etc., so that the display mechanism 100 can achieve relatively stable movement at a lower speed. And the transmission direction of the force output by the driver 310 can also be changed by the worm gear assembly, and the specific force transmission method can be designed according to the spatial layout, which is conducive to improving space utilization and realizing the miniaturization design of the product. In addition, the rotational motion output by the worm gear assembly can be converted into a linear motion along the axial direction of the screw 350 by the screw nut assembly, thereby driving the display mechanism 100 to move in the slide groove 211.

[0085] In the embodiment of the present application, optionally, as Figure 10 As shown, the worm gear assembly includes a transmission worm 320, a worm gear 330, and a transmission gear 340; the transmission worm 320 is connected to the output end of the driver 310, the worm gear 330 is meshed with the transmission worm 320, and the transmission gear 340 is meshed with the worm gear 330. Specifically, the worm gear 330 includes a worm wheel and a worm 331 that mesh with each other, wherein the worm wheel meshes with the transmission worm 320, and the worm 331 meshes with the transmission gear 340, and the axial direction of the worm wheel is parallel to the axial direction of the worm 331. For example, the worm wheel and the transmission gear 340 can be helical gears. In this way, the power output from the driver 310 is transmitted to the worm wheel of the worm gear 330 via the transmission worm 320. The axial direction of the transmission worm 320 is perpendicular to the axial direction of the worm wheel of the worm gear 330. This changes the rotation of the driver 310 about the axial direction of the transmission worm 320 into rotation about the axial direction of the worm wheel of the worm gear 330. The power is then transmitted to the worm 331 of the worm gear 330, which changes the rotation about the axial direction of the worm 331 into rotation about the axial direction of the transmission gear 340. The axial direction of the worm 331 is perpendicular to the axial direction of the transmission gear 340. This changes the direction of the force transmitted from the driver 310 to the transmission worm 320 by 180° and then outputs it to the lead screw and nut assembly. This allows the transmission worm 320 and the lead screw 350 of the lead screw and nut assembly to be arranged in parallel, significantly reducing the layout space of the driver 310 and the transmission structure.

[0086] For example, in the embodiment of the present application, the axial direction of the transmission worm 320 and the axial direction of the worm wheel of the worm gear 330 can also be set at an angle, such as 80°, 60°, 30° or 100°, etc. Similarly, the axial direction of the worm 331 of the worm gear 330 and the transmission gear 340 can also be set at an angle, such as 80°, 60°, 30° or 100°, etc. In addition, the axial direction of the worm wheel of the worm gear 330 and the axial direction of the worm 331 can also be perpendicular, or set at an angle, which can be set according to the actual layout requirements, and the embodiment of the present application does not limit this.

[0087] In other optional embodiments of the present application, the driver 310 can also directly drive the screw 350 to rotate, for example, by using a reduction motor to drive the screw 350 to rotate, and the screw 350 drives the nut 360 to move along the axial direction of the screw 350, and can also drive the display mechanism 100 to move more smoothly in the slide groove 211 at a lower speed. The embodiments of the present application may not limit the specific implementation methods of the driver 310 and the transmission structure.

[0088] Optionally, the display screen device further includes a rotating member 500, which is rotationally connected to the lead screw and nut assembly, and the display mechanism 100 is rotationally connected to the rotating member 500. Specifically, the rotating member 500 is rotationally connected to the nut 360 of the lead screw and nut assembly, and the display mechanism 100 is rotationally connected to the rotating member 500 via the movable assembly 400. In this way, when the movable assembly 400 moves from the linear groove of the slide groove 211 to the curved groove, the rotation of the rotating member 500 relative to the lead screw and nut assembly, and the rotation of the movable assembly 400 relative to the rotating member 500, enable rotational freedom between the rotating member 500, the display mechanism 100, and the transmission structure, thereby achieving relatively stable and smooth transmission of torque.

[0089] For example, in the embodiment of the present application, the rotating member 500 may be a rotating plate having a first opening 510 and a second opening 520 formed therein. A connecting sleeve 362 is disposed on the outer surface of the connecting shaft 361 of the nut 360. The connecting shaft 361 and the connecting sleeve 362 are both inserted through the first opening 510, and the connecting sleeve 362 is rotatable within the first opening 510. Furthermore, a first gasket 441 is disposed between the connecting shaft 361 and the rotating member 500 to effectively buffer and absorb friction and other energy between the nut 360 and the rotating member 500. Furthermore, the fastener 430 and the sleeve 440 of the movable assembly 400 are inserted through the second opening 520, and the sleeve 440 is rotatable within the second opening 520. Furthermore, a second gasket is disposed between the fastener 430 and the connecting plate 220 to effectively buffer and absorb friction and other energy between the fastener 430 and the rotating member 500.

[0090] In the embodiment of the present application, optionally, the screw and nut assembly includes a screw 350 and a nut 360, part of the worm gear assembly is sleeved on the screw 350, the nut 360 is sleeved on and meshed with the screw 350, and the nut 360 is rotatably connected to the rotating member 500. Specifically, the transmission gear 340 of the worm gear assembly is sleeved on the screw 350, the transmission gear 340 drives the screw 350 to rotate, the nut 360 is meshed with the screw 350, and the screw 350 drives the nut 360 to move along the axial direction of the screw 350, thereby converting the rotational motion of the screw 350 into a linear motion of the nut 360 along the axial direction of the screw 350, and then driving the display mechanism 100 to move along the slide groove 211 through the rotating member 500 and the movable assembly 400.

[0091] Optionally, in an embodiment of the present application, the driving mechanism 300 includes a housing 370, and the driver 310, the transmission worm 320, the worm gear 330, the transmission gear 340, the lead screw 350 and the nut 360 are all arranged in the housing 370; the housing 370 is provided with an opening 372 extending along the axial direction of the lead screw 350, and the nut 360 is provided with a protruding connecting shaft 361, at least part of the connecting shaft 361 extends out of the opening 372, and the connecting shaft 361 can be rotatably connected to the rotating member 500. The shell 370 has a cavity, which provides installation space for various transmission parts such as the driver 310 and the transmission worm 320, the worm gear 330, the transmission gear 340, the screw 350 and the nut 360. An opening 372 extending along the axial direction of the screw 350 is opened in the shell 370, so that at least part of the connecting shaft 361 of the nut 360 can extend out of the opening 372 and move along the axial direction of the screw 350, providing space for the nut 360 to drive the movement of the rotating part 500, thereby avoiding interference of the shell 370 with the movement of the rotating part 500 driven by the nut 360.

[0092] For example, in an embodiment of the present application, two bearings 351 can also be installed in the housing 370, and the two bearings 351 are arranged at intervals. The two ends of the screw 350 are respectively installed on the two bearings 351, so that the screw 350 can rotate more flexibly and smoothly in the housing 370. For example, two end caps 371 are respectively provided at both ends of the housing 370, one end cap 371 is used to close the end of the housing 370 close to the driver 310, and the other end cap 371 is used to close the end of the housing 370 close to the worm gear assembly. For example, by opening the two end caps 371 respectively, the driver 310 and the transmission worm 320, the worm gear 330, the transmission gear 340, the screw 350 and the nut 360 located inside the housing 370 can be assembled. After the assembly is completed, the two end caps 371 are respectively connected to the two ends of the housing 370 to achieve the sealing of the housing 370.

[0093] In the embodiment of the present application, the display mechanism 100 optionally includes a display screen 110 and a mounting plate 120. The display screen 110 is connected to the mounting plate 120, and the mounting plate 120 is movably connected to the position adjustment mechanism 200. The mounting plate 120 is provided with a mounting hole 121. In this way, the display mechanism 100 and the position adjustment mechanism 200 are movably connected through the mounting plate 120, thereby avoiding any impact on the display screen 110. The mounting hole 121 is provided on the mounting plate 120, so that the fastener 430 and the shaft sleeve 440 of the movable assembly 400 are inserted into the mounting hole 121 for assembly.

[0094] For example, in an embodiment of the present application, the number of mounting holes 121 can be two, and the two mounting holes 121 are arranged at intervals, corresponding to the first slide groove 212 and the second slide groove 213 respectively, and the first movable member 410 passes through one of the mounting holes 121 and the first slide groove 212, and the first movable member 410 is movably connected to the first slide groove 212; the second movable member 420 passes through the other mounting hole 121 and the second slide groove 213, and the second movable member 420 is movably connected to the second slide groove 213.

[0095] Optionally, in the embodiment of the present application, Figure 9 As shown, there are two drive mechanisms 300, each connected to one side of the display mechanism 100. The two drive mechanisms 300 simultaneously provide driving force to both sides of the display mechanism 100, so that the display mechanism 100 is subjected to a more uniform force along both sides of the position adjustment mechanism 200, resulting in a more stable and reliable movement effect.

[0096] In the embodiment of the present application, optionally, as Figure 15 As shown, the driving mechanism 300 is disposed in the middle area of the position adjustment mechanism 200. The display screen device further includes a connecting rod (not shown in the figure), which is connected to the display mechanism 100. Specifically, the connecting rod can be connected to the rotating member 500, the rotating member 500 is movably connected to the movable assembly 400, and the movable assembly 400 is movably connected to the display mechanism 100. That is, the connecting rod is connected to the display mechanism 100 via the rotating member 500 and the movable assembly 400.

[0097] For example, in an embodiment of the present application, the connecting rod may extend toward one side of the display mechanism 100, and through the rotating member 500 and the movable assembly 400, the connecting rod transmits force to one side of the display mechanism 100. In another embodiment of the present application, the opening 372 of the housing 370 of the drive mechanism 300 may face away from the display mechanism 100, and the connecting rod may extend to both sides of the display mechanism 100. Through the rotating member 500 and the movable assembly 400, the connecting rod transmits force to both sides of the display mechanism 100 simultaneously. The specific configuration of the connecting rod and the drive mechanism 300 is not limited in this embodiment of the present application.

[0098] In addition, in the embodiment of the present application, the number of driving mechanisms 300 can also be one, and one driving mechanism 300 can be located on the left or right side of the display mechanism 100, and perform unilateral driving on the movement of the display mechanism 100 relative to the position adjustment mechanism 200, and can also realize the storage and use of the display mechanism 100, as well as the adjustment of the display angle of the display mechanism 100, etc. The embodiment of the present application may not limit the specific setting method of the driving mechanism 300.

[0099] For example, in an embodiment of the present application, the assembly process of the display screen device may be as follows: first, the connecting sleeve 362 is installed into the first opening 510 of the rotating member 500, and the two sleeves 440 are respectively mounted on the two fasteners 430. Then, the mounting plate 120 of the display mechanism 100 is placed in the accommodating cavity of the position adjustment mechanism 200. One fastener 430 is sequentially passed through the first opening 510 of the rotating member 500, the first gasket 441, the first slide groove 212, and a mounting hole 121 of the mounting plate 120. The mounting hole 121 may be a threaded hole, and the fastener 430 may be a screw, which is threadedly connected to the threaded hole. Another fastener 430 is sequentially passed through the second opening 520 of the rotating member 500, the second gasket, the second slide groove 213, and another mounting hole 121 of the mounting plate 120, thereby assembling the two fasteners 430 with the display device and the slide rail 210 of the position adjustment structure, respectively.

[0100] Then, the transmission worm 320 is connected to the output end of the driver 310, and the driver 310 is installed in the housing 370. The end cap 371 near the driver 310 is connected to the housing 370, for example, by screws. Next, two bearings 351 are installed in the housing 370, and the transmission gear 340 is sleeved on one end of the lead screw 350. The lead screw 350 and the transmission gear 340 are installed in the housing 370 and respectively mounted on the two bearings 351. The nut 360 is sleeved on the threaded structure of the lead screw 350, and the connecting shaft 361 on the nut 360 extends out of the opening 372 on the side of the housing 370. The worm gear 330 is then installed in the housing 370, meshing with the transmission worm 320 and the transmission gear 340 respectively. Then, the end cap 371 near the worm gear 330 is connected to the housing 370 to achieve the sealing of the end of the housing 370.

[0101] Finally, the connecting shaft 361 of the nut 360 is inserted into the first opening 510 of the rotating member 500, so that the connecting shaft 361 is embedded in the connecting shaft sleeve 362, completing the assembly of the entire display screen device. The above assembly sequence can be adjusted according to actual needs, and some assembly steps can be performed in a different order or simultaneously. This is merely an example and does not limit the present invention.

[0102] In summary, the display screen device described in the embodiments of the present application can at least include the following advantages:

[0103] In an embodiment of the present application, the display screen device is applied to an instrument panel, the instrument panel having an instrument panel, and the display screen device includes: a display mechanism, a position adjustment mechanism, and a drive mechanism; the position adjustment mechanism is used to connect to the instrument panel, the display mechanism is movably connected to the position adjustment mechanism, and the drive mechanism is connected to the display mechanism; the drive mechanism drives the display mechanism to move along the position adjustment mechanism so that the display mechanism moves between a use position and a storage position, wherein the use position at least partially exposes the instrument panel, and the storage position at least partially stores the display mechanism in the instrument panel. In this way, when the display mechanism is needed, the drive mechanism can drive the display mechanism to move along one end of the position adjustment mechanism to the other end, so that the display mechanism at least partially exposes the instrument panel, so that the user can use the exposed display mechanism. When the display mechanism is not needed, the drive mechanism can reversely drive the display mechanism to move along the other end of the position adjustment mechanism to one end, so that the display mechanism is not exposed but stored in the instrument panel, thereby reducing the risk of the user accidentally touching the display mechanism, reducing damage to the display mechanism, and reducing bumps and injuries to the user, thereby improving the safety of the display screen device.

[0104] Reference Figures 16 to 18 , shows a flowchart of the steps of a display screen control method proposed in an embodiment of the present application, wherein the display screen control method is applied to the display screen device, and the method includes:

[0105] Step 101: Obtain control instructions.

[0106] For example, in the embodiment of the present application, the driver 310 of the drive mechanism 300 can directly obtain a control instruction, such as an opening instruction, so that the display mechanism 100 moves along the position adjustment mechanism 200 to the use position, or a storage instruction, so that the display mechanism 100 moves along the position adjustment mechanism 200 to the storage position. In addition, the control instruction can also be sent to the driver 310 by the vehicle controller, and this embodiment of the present application is not limited to this.

[0107] Optionally, the control command includes a touch command generated by pressing a touch button, a voice command, or a command to identify a target person at a target location. That is, a user can trigger a control command for the display device by pressing a touch button, thereby manually controlling the display device. Alternatively, a control command can be triggered by issuing a voice command, such as "turn on the display" or "turn off the display."

[0108] In addition, the control instructions are obtained by identifying the target person at the target location. For example, the image of the target location can be analyzed by the camera. When the target person in the image of the target location appears or disappears, the recognition instruction is sent, triggering the control instructions of the display device, thereby automatically controlling the display device. For example, the camera is used to obtain information about the passenger in the front passenger seat. When the passenger appears in the front passenger seat, the display device automatically receives the control instruction to open. When the passenger disappears, the display device automatically receives the control instruction to fold.

[0109] For example, in an embodiment of the present application, the passenger information of the front passenger seat can also be obtained through the seat pressure sensor, so as to implement the recognition instruction of the target person at the target location. For example, when the pressure sensor of the front passenger seat detects a pressure signal within the preset threshold range, it is determined that there is a passenger in the front passenger seat, and a recognition instruction is sent, which triggers the display device to automatically obtain the opening control instruction. When the pressure sensor of the front passenger seat detects that the pressure signal is not within the preset threshold range, it is determined that the passenger in the front passenger seat has left, and a recognition instruction is sent, which triggers the display device to automatically obtain the storage control instruction.

[0110] Step 102: Based on the control instruction, the driving mechanism 300 drives the display mechanism 100 to move along the position adjustment mechanism 200 so that the display mechanism 100 moves between the use position and the storage position. In the use position, the display mechanism 100 is at least partially exposed on the dashboard 600, and in the storage position, the display mechanism 100 is stored in the dashboard 600.

[0111] After the display screen device receives a control command, the drive mechanism 300 drives the display mechanism 100 to move along the position adjustment mechanism 200 so that the display mechanism 100 moves to a position corresponding to the control command. For example, if the touch button receives a touch command by being pressed once, or if the camera detects the presence of a passenger in the passenger seat, the display screen device is instructed to open the display mechanism 100. The drive mechanism 300 drives the display mechanism 100 to move along the position adjustment mechanism 200 so that it is exposed on the instrument panel 600 and moves to a use position for user use. If the touch button receives a touch command by being pressed again or double-clicked, or if the camera detects the absence of the passenger in the passenger seat, or if the pressure sensor detects the passenger leaving the passenger seat, the display screen device is instructed to retract the display mechanism 100. The drive mechanism 300 drives the display mechanism 100 to move along the position adjustment mechanism 200 so that it is retracted below the instrument panel 600 and moves to the retracted position, thereby implementing the retractable function of the display mechanism 100.

[0112] Optionally, the method may further include step 103: acquiring a current display angle between the display mechanism 100 and the user in the use position.

[0113] At this time, the display mechanism 100 is in the open state and can identify the position or height of the passenger through the camera. For example, the current display angle between the display mechanism 100 and the user can be determined by the distance and angle between the passenger's eye position and the display screen 110 of the display mechanism 100, as well as the tilt angle of the display mechanism 100.

[0114] Step 104 : When the current display angle exceeds the target display angle, the driving mechanism 300 adjusts the display angle of the display mechanism 100 to the target display angle.

[0115] Specifically, the aforementioned camera can identify parameters such as the passenger's position or height, as well as the passenger's eye position, and calculate an optimal display angle range between the display mechanism 100 and the passenger as a target display angle. The target display angle can be a threshold range. If the current display angle between the display mechanism 100 and the user obtained in step 103 exceeds the target display angle, the drive mechanism 300 will drive the display mechanism 100 to rotate along the position adjustment mechanism 200 to adjust the display angle of the display mechanism 100 until the display angle is adjusted to the target display angle, which is within the optimal display angle range between the passenger and the display mechanism 100.

[0116] In the embodiment of the present application, optionally, while the display mechanism 100 automatically adjusts the display angle, the user can also rotate the display mechanism 100 to manually adjust its display angle, so that the display mechanism 100 is adjusted to a display angle that is optimal for the user's viewing experience.

[0117] After the display angle of the display mechanism 100 in the use state is confirmed, the driving mechanism 300 stops outputting the driving, so that the display mechanism 100 is in a locked state.

[0118] like Figure 17 , shows a schematic flow chart of the steps of manually opening the display device and adjusting the display angle of the display mechanism 100 when the touch button is pressed under the touch command in the embodiment of the present application. Figure 18 , shows a schematic flow chart of the steps of automatically opening the display screen device and adjusting the display angle of the display mechanism 100 in response to the recognition instruction of the target person at the target position in an embodiment of the present application. The specific steps are as described above, and the embodiment of the present application will not be repeated here.

[0119] In summary, the display screen control method described in the embodiments of the present application can at least include the following advantages:

[0120] In an embodiment of the present application, the display screen control method includes: obtaining a manipulation instruction; based on the manipulation instruction, a driving mechanism drives the display mechanism to move along the position adjustment mechanism so that the display mechanism moves between a use position and a storage position, wherein in the use position, the display mechanism is at least partially exposed on the instrument panel, and in the storage position, the display mechanism is stored in the instrument panel. In this way, when the display mechanism needs to be used, the driving mechanism can drive the display mechanism to move along one end of the position adjustment mechanism to the other end, so that the display mechanism is at least partially exposed on the instrument panel, so that the user can use the exposed display mechanism. When the display mechanism is not needed, the driving mechanism can reversely drive the display mechanism to move along the other end of the position adjustment mechanism to one end, and the display mechanism is not exposed but stored in the instrument panel, thereby reducing the risk of the user accidentally touching the display mechanism, reducing damage to the display mechanism, and reducing bumps and injuries to the user, thereby improving the safety of the display screen device.

In the use position, the display mechanism is at least partially exposed on the instrument panel, and in the storage position, the display mechanism is stored in the instrument panel. In this way, when the display mechanism needs to be used, the drive mechanism can drive the display mechanism to move along one end of the position adjustment mechanism to the other end, so that the display mechanism is at least partially exposed on the instrument panel, so that the user can use the exposed display mechanism. When the display mechanism is not needed, the driving mechanism can reversely drive the display mechanism to move along the other end of the position adjustment mechanism to one end. The display mechanism is not exposed but is stored in the instrument panel, thereby reducing the risk of the user accidentally touching the display mechanism, reducing damage to the display mechanism, and reducing bumps and injuries to the user, thereby improving the safety of the display screen device.
