The first power mechanism 111 and the first transmission mechanism 112 are arranged at the rearmost end of the display screen 101; the second power mechanism 121 and the second transmission mechanism 122 are disposed on the front side of the first power mechanism 111 and the first transmission mechanism 112, and are relatively close to the display screen 101; the third power mechanism 131 and the third transmission mechanism 132 are disposed on the front sides of the second power mechanism 121 and the second transmission mechanism 122, and are relatively close to the display screen 101. This setting makes power unit and drive mechanism keep away from the display screen, very big reduction display screen rear space, can realize effectual noise isolation simultaneously. It should be understood that the positions of the first rotation mechanism 110, the second rotation mechanism 120, and the third rotation mechanism 130 relative to the display screen 101 and relative to each other may also have other forms, for example, the positions of the second rotation mechanism 120 and the third rotation mechanism 130 may be interchanged. The application is not limited to the specific form of the display screen angle adjusting device.
In one possible design, as shown in fig. 4, the second power mechanism 121 and the third power mechanism 131 may be disposed inside the first base 190, and the first gear 1123 in the first transmission mechanism 112 is fixedly connected with the first base 190, at this time, during the rotation of the first rotation shaft 113, the first base will rotate along with the first gear 1123, and meanwhile, during the revolution around the first rotation shaft 113, the second power mechanism 121 and the third power mechanism 131 do not have relative movement with the respective transmission mechanisms, so that the corresponding angles of the Y/Z axes remain unchanged when the display screen rotates around the X axis.
Fig. 5 is a general assembly view of the display screen angle adjusting apparatus, which further includes a support case 180. The display screen angle adjusting device is modularized through the structure, so that the display screen angle adjusting device is easy to assemble and disassemble, and the universality of the device is improved.
Further, the embodiment of the present application provides a display screen angle adjustment system, where the display screen angle adjustment system includes a controller, such as any one of the display screen angle adjustment devices shown in fig. 1 to 5, where the controller is respectively connected to the display screen 101, the first power mechanism 111, the second power mechanism 121, and the third power mechanism 131 in the display screen angle adjustment device, and the controller acquires angle information to be adjusted of the display screen 101 by acquiring input signals of the display screen 101, so as to control the first power mechanism 111, the second power mechanism 121, and the third power mechanism 131 to start and stop, so as to implement three-dimensional angle adjustment of the display screen 101 around the Y axis, the Z axis, and the X axis. Three ways of adjusting the system to control the rotation of the display 101 about the Y, Z and X axes are further described below with reference to fig. 6-8, respectively. Fig. 6 is a power flow diagram of a display screen angle adjusting system provided by an embodiment of the present application for controlling a display screen to rotate around a Y-axis. Fig. 7 and 8 are respectively power flow diagrams for controlling the display screen to rotate around the Z axis and the X axis.
(1) Angle adjustment for rotation of display screen around Y-axis direction
Specifically, in the angle adjustment in which the display screen 101 rotates around the Y-axis direction, the display screen 101 transmits angle information to be adjusted to the controller, and the angle information may be, for example, X, Y, Z axis constituting one coordinate information in the three-dimensional coordinate system; the controller controls the second power mechanism 121, i.e. the motor to work according to the angle information, drives the second gear 1223 and/or the first screw 1222 in the second transmission mechanism 122 to rotate, and under the action of the guide rod 124, makes the first screw nut 1221 implement linear translation, and further drives the first push rod 123 to move, so as to push the display screen 101 to rotate around the Y axis. The angular adjustment range of the display screen rotating around the Y axis can be set as desired, for example, in one possible setting, the angular adjustment range of the display screen rotating around the Y axis can be [ -30 °,30 ° ].
Optionally, while the system adjusts the display screen to rotate around the Y axis, the controller may also acquire the current state and the rotation angle of the display screen recorded by the gyroscope inside the display screen 101, compare the current state and the rotation angle with the input angle information, and if the values match, control the second power mechanism 121 to stop working, so as to realize closed-loop control of the system.
(2) Angle adjustment for rotation of display screen around Z-axis direction
Also, in the angle adjustment of the rotation of the display screen 101 around the Z-axis direction, the display screen 101 transmits the angle information to be adjusted to the controller, and the controller controls the third power mechanism 131 to work according to the angle information, so as to drive the third gear 1323 and/or the second screw 1322 to rotate, and under the action of the guide rod 134, the second screw nut 1321 realizes linear translation; and then drives the second push rod 133 to move to push the display screen 101 to rotate around the Z axis. Optionally, when the system adjusts the display screen 101 to rotate around the Z axis, the controller compares the acquired current state and rotation angle of the display screen with the input angle information, and further controls the motor to stop working, so that closed-loop control of the system can be realized. The angular adjustment range of the display screen about the Z axis may be set as desired, for example, in one possible setting, the angular adjustment range of the display screen about the Z axis may be [ -30 °,30 ° ].
(3) Angle adjustment for rotation of display screen around X-axis direction
In the angular adjustment of the display screen rotating around the X-axis direction, since both the Y-axis and the Z-axis are connected to the display screen 101, the angles of the Y-axis and the Z-axis also change during the rotation of the display screen 101, so that the Y-axis and the Z-axis also need to rotate synchronously. The display screen transmits the angle information to be adjusted to the controller, and the controller controls the first power mechanism 111 to work according to the angle information so as to drive the first transmission mechanism 112; which in turn drives the first rotation shaft 113 to rotate. Meanwhile, the controller also controls the second power mechanism 121 and the third power mechanism 131 to work and drives the components of the respective rotating mechanisms to work, so that the constant angles of the Y axis and the Z axis of the display screen 101 are realized in the process of rotating the X axis.
Secondly, if the angle adjustment information of the controller includes the angle information rotating around the Y or Z axis, the display screen 101 transmits the angle signal to the controller, and the controller controls the first power mechanism 111, the second power mechanism 121 and the third power mechanism 131 to operate simultaneously and drive the components of the respective rotating mechanisms to operate, so as to realize the angle adjustment of the display screen rotating around the Y/Z axis while ensuring that the display screen 101 rotates around the X axis. The angular adjustment range of the display screen about the X-axis may be set as desired, for example, in one possible setting, the angular adjustment range of the display screen about the X-axis may be [0 °,180 ° ].
In addition to the automatic adjustment mode, a manual adjustment mode may be provided in the system. In a manual adjustment mode, sensing pressure generated when the display screen is pushed by a hand through a pressure sensor, wherein the pressure sensor transmits corresponding pressure information to a controller; and the controller controls the corresponding power mechanism to work according to the pressure information. Optionally, a pressure threshold value can be set in the controller, and when the controller detects that the pressure represented by the received pressure information reaches the threshold value, the corresponding motor is controlled to work, so that the adjustment of the corresponding angle of the display screen is realized. When the display screen is adjusted in place, the pressure signals corresponding to the pressure sensors are weakened, and if the pressure of each shaft is lower than a threshold value set in the controller, the controller does not perform any feedback or output; after the adjustment is completed, the current state is saved and the manual adjustment mode is exited, and at the same time, the controller will not react to the sensor signal, thereby achieving the locking of the display screen position.
Optionally, the current threshold value of each power mechanism can be set in the controller, the controller detects the current of each power mechanism, when the current exceeds the set threshold value, the motor is controlled to stop working, and meanwhile, the controller can also control the power mechanism with the current exceeding the threshold value to reverse a certain angle, so that the anti-clamping function is realized.
Further, the controller can also receive control signals of upper-layer application software, so that the application software control of the display screen is realized, and further, more intelligent angle adjustment is realized. For example, automatic vertical screen in the case of navigation, automatic horizontal screen in movie, game mode, vibration in music mode, etc.
The controller can also be matched with other devices, such as a camera, a loudspeaker and the like, so as to realize a more humanized man-machine interaction function. For example, the controller can determine the sound source position through sound information collected by the loudspeaker, or determine the position information of personnel in the vehicle through image collected by the camera, and then control the rotation angle of the display screen to adjust in real time, or control the display screen to nod, shake the head, and the like, so as to realize more intelligent communication and interaction. The display screen angle memorizing function with more intellectualization and convenience can be realized through the account information binding of the driver.

It should be appreciated that the upper level control information may be from a display screen, a controller, a pressure sensor, etc., and may include upper level road condition information, driver adjustment information, entertainment system simulation information, camera information, etc.
