The driving gear 24 rotates and drives the rotating gear 23 to start working. The rotating gear 23 rotates and drives the four support frames 11 to rotate through the clamping teeth 22 on the direction rotating frame 21, thereby driving the telescopic component 1 to rotate. The telescopic component 1 indirectly drives the electronic screen 9 to rotate through the ball head 17 and the connecting component 6 to complete the horizontal and vertical screens. In this embodiment, when the rotating gear 23 rotates 90 degrees counterclockwise and collides with the end limit block 51 of the angle limiter 5, it stops rotating. At this time, the large screen is horizontal. When the rotating gear 23 rotates 90 degrees clockwise and collides with the end limit block 51 of the top angle limiter 5, it stops rotating. At this time, the large screen is vertical;

[0057] When adjusting the tilt direction, the four power telescopic components are adjusted according to the adjustment needs of the electronic screen 9. The angle encoder 15 calculates the number of rotations of the telescopic motor 14 to calculate the extended length of the telescopic rod 12. The telescopic motor 14 drives the telescopic rod 12 to extend and retract, and the telescopic rod 12 indirectly drives the ball head 17 to extend and retract, so as to adjust the direction angle of the electronic screen 9. Fig.16As shown, the support frames 11 of the four power telescopic components a, b, c, and d are extended to the same length, and the electronic screen 9 is in a vertical shape. The support frames 11 of the power telescopic components a and b are stationary, and the support frames 11 of the power telescopic components c and d are extended, and the electronic screen 9 flips upward. The support frames 11 of the power telescopic components a and b are extended, and the support frames 11 of the power telescopic components c and d are stationary, and the electronic screen 9 flips downward. The support frames 11 of the power telescopic components b and c are extended, and the support frames 11 of the power telescopic components a and d are stationary, and the electronic screen 9 flips to the left. The support frames 11 of the power telescopic components a and d are extended, and the support frames 11 of the power telescopic components b and c are stationary, and the electronic screen 9 flips to the right. The support frame 11 of the power telescopic component a is stationary, and the support frames 11 of the power telescopic components b, c, and d are extended, and the electronic screen 9 flips obliquely upward. Similarly, by adjusting the extended length of the support frames 11 of the four power telescopic components, the electronic screen 9 can be tilted and flipped in various directions.

[0058] During the braking and clamping operation, when the support frame 11 is rotated into place or the extension and retraction is completed, the brake assembly 4 intervenes in the operation in time. During operation, the clamping motor 46 drives the screw 44 to rotate through the reduction gear box 45. In this patent, the brake bracket 41 is tightened when the screw 44 rotates forward, and the brake bracket 41 is loosened when the screw 44 reverses. The screw 44 moves axially through the nut 43 to realize the upper end of the brake bracket 41 and the lower end of the brake bracket 41 to approach and complete the clamping of the column structure formed by assembling multiple support frames 11, so that the column structure formed by assembling multiple support frames 11 is more firmly connected to the fixing assembly 3, and at the same time, the electronic screen 9 will be fixed more firmly, and it will be more stable when the hand touches the screen.

[0059] The present invention patent proposes a large universally adjustable rotating screen that can perform human-computer interaction in a variety of ways during use, mainly including the following aspects.

[0060] 1. Manual adjustment: There are touch buttons for up, down, left, right, tilt angle, rise, fall, rotation, etc. on the electronic screen 9. By touching the corresponding buttons, the tilt angle and rotation of the electronic screen 9 can be adjusted.

[0061] 2. Quick adjustment: Set several commonly used electronic screen 9 tilt angles as shortcuts, and you can customize the name. By touching the shortcut key, the electronic screen 9 is directly adjusted to the corresponding angle.

[0062] 3. Memory adjustment: Automatically memorize the last adjusted angle. When the adjustment is triggered, it will automatically adjust to the last angle or the commonly used angle, eliminating the need for special adjustment steps.

[0063] 4. Interaction adjustment: By setting interaction rules with the app, when the set rules are met, the angle adjustment of the electronic screen 9 is triggered. For example, when navigation starts, the electronic screen 9 automatically rotates and tilts to a common angle. For example, when the vehicle speed reaches the set 120km / h, the electronic screen 9 automatically tilts toward the driver's side to ensure safe driving for the driver, reduce the time of turning the head to view the electronic screen 9, and improve viewing accuracy.

[0064] 5. Voice adjustment: You can interact through the car voice assistant. For example, say that the electronic screen 9 is tilted toward the driver's side, specify the tilt direction and angle, and the tilt angle and rotation of the electronic screen 9 can be interactively adjusted through voice.

[0065] 6. Intelligent adjustment: (1) To enhance the atmosphere, based on the existing technology, when the vehicle passes the key (including NFC key) and determines the regular driver, in addition to the conventional front and rear adjustment, height adjustment and steering wheel height adjustment of the driver's seat, the camera in the front of the workshop captures the height of the human eye, and the background calculation is used to obtain the inclination angle of the electronic screen 9, and automatically adjust the inclination angle of the electronic screen 9 to be perpendicular to the eye light, so as to make it look the best and increase the atmosphere of the workshop.

[0066] (2) When the vehicle is driving, the electronic screen 9 reflects light, causing the viewing angle to decrease. The tilt angle of the electronic screen 9 can be obtained through large-scale model cloud computing based on the height of human eyes, the direction of eye light, the position of the sun, the driving direction, etc., so as to achieve the best viewing experience and make adjustments in real time.

[0067] (3) Through regular adjustments, recording user preferences, and continuous training, the tilt angle and rotation scene of the electronic screen 9 are made more in line with user habits.

Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of this patent are within the scope of protection of the technical solution of this patent.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this patent, rather than to limit it. Although this patent has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents, but these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of this patent.
