[0043] The driving device 40 cooperates with the moving module 20 and the rotating module 30, the driving device 40 can drive the moving module 20 to move and drive the rotating module 30 to rotate, so that the display screen 200 is switched between a first state and a second state, the first state can be a horizontal screen state, the second state can be a vertical screen state, or the first state is a vertical screen state and the second state is a horizontal screen state, the driving device 40 can be one, which simultaneously drives the moving module 20 to move and the rotating module 30 to rotate, the driving device 40 can also be two, which respectively drives the moving module 20 and the rotating module 30.

[0044] That is, when the display screen 200 switches the state, under the action of the driving device 40, the rotating module 30 drives the display screen 200 to rotate, and the moving module 20 drives the display screen 200 to move up and down, so that the display screen 200 can have rotating and moving actions. For example, when the display screen 200 switches from the first state to the second state, the display screen 200 can rotate and descend at the same time, and then when it switches to the second state, the upper edge of the display screen 200 will not be too high to affect the driving sight line; when the display screen 200 switches from the second state to the first state, the display screen 200 can rotate and move up at the same time, and then when it switches to the first state, the height can be adjusted to achieve a better display viewing angle and provide a comfortable use experience.

[0069] As shown in FIG. 6, in some embodiments, when the driving device 40 drives the rotating module 30 to rotate to switch the display screen 200 from the first state to the second state, the moving module 20 moves downward, and the rotation axis of the rotating module 30 can be perpendicular to the display screen 200 and coincide with the geometric center of the display screen 200. FIG. a shows that the display screen 200 is in the first state, and FIG. b shows that the display screen 200 is in the second state. When the moving module 20 moves downward, the geometric center of the display screen 200 moves downward, so that the upper edge of the display screen 200 is not too high when the display screen 200 is switched to the second state, thereby avoiding that the switching of the display screen 200 affects the user's line of sight.

[0070] As shown in FIG. 6, the display screen 200 is roughly rectangular, and the upper edge of the display screen 200 in the first state is at the same height as the upper edge of the display screen 200 in the second state. Therefore, the upper edge of the display screen 200 will not be too high to affect the driving line of sight, and the display screen 200 can always be kept at a suitable height position to achieve a suitable display viewing angle, thereby providing a safe and comfortable use experience.

[0071] As shown in FIG. 7, the control mode of the display screen according to the embodiment of the present disclosure comprises:

[0072] S1, receiving a switching instruction of a display screen;

[0073] S2, drive the driving device to work, control the moving module to move and the rotating module to rotate.

[0074] According to the control method of the display screen, when the switching instruction is received, the moving module and the rotating module are driven to move and rotate by the driving device, so that the display screen can realize the switching between the second state, and the display screen can adjust the moving position to achieve a suitable display viewing angle when switching between the first state and the second state, thereby providing a safe and comfortable use experience.

[0075] In some embodiments, after the moving module is controlled to move and the rotating module is controlled to rotate, the method further comprises:

[0076] S3, judging whether the display screen moves to the position;

[0077] S4, when the display screen moves to the position, controlling the display content to be adaptively adjusted.

[0078] The switching instruction can be any one of a key, a voice, and a gesture.

[0079] In addition, the judgment of whether the display screen moves to the position can be detecting information of the driving device, for example, detecting a current of a driving motor. Since the rotating module rotates to the position, the driving motor is blocked (when the first limiting member on the rotating module cooperates with the second limiting member on the moving module, the driving motor is limited to further rotate), the current of the driving motor suddenly increases, and the display screen moves to the position can be determined by detecting the change of the current. Of course, a sensor can also be arranged to detect whether the display screen moves to the position.

[0080] According to the control method of the display screen, after the display screen moves to the position, the display content is adaptively adjusted, and the use experience can be further improved.

[0081] In some embodiments, when the instruction of switching the display screen 200 is received, the driving motor 41 of the driving device 40 starts to work, and after the power is transmitted to the connecting piece 32 of the rotating module 30 through the first worm 421 and the second worm 411, the connecting piece 32 connects the rotating disc 31 through the clamping convex 321, drives the rotating disc 31 to rotate, the gear ring 422 on the second worm 411 transmits the power to the rotating gear 221 of the rotating piece 22 through the gear 423, and then transmits the power to the lead screw 11, under the guidance of the sliding groove 12 of the fixed support 10, the movement of the lead screw 11 makes the whole driving device 40, the moving module 20 and the rotating module 30 move vertically downward relative to the fixed support 10, when the rotating disc 31 rotates to the position, the first limiting piece 36 on the rotating disc 31 cooperates with the second limiting piece of the moving body 21 to block the rotation, the motor stops moving, the whole mechanism is locked, and the movement is completed; the movement in the opposite direction only needs to change the rotating direction of the motor, so as to realize the combined movement of the rotation of the rotating disc 31 and the vertical movement.

[0082] Other configurations and operations of the vehicle according to the embodiments of the present disclosure are known to those skilled in the art, and will not be described in detail herein. Among them, the up-down direction, the left-right direction and the front-rear direction are based on the up-down direction, the left-right direction and the front-rear direction shown in the figure.
