[0030] In an embodiment of the utility model, support subassembly 3 is established to installation board 1 outside, support subassembly 3 includes first asynchronous motor 31, and first asynchronous motor 31 output shaft outside fixed mounting is in the center inside of driving gear 32, bearing sleeve 33 is fixedly installed on the bottom of fixed seat 2, and ball 34 is arranged in the inside of bearing sleeve 33 and rolls, driven gear ring 35 is rotatably installed in the inside of bearing sleeve 33, driving gear 32 engages driven gear ring 35, and arc slot 36 is formed in the outer wall of driven gear ring 35, ball 34 rolls and is attached on arc slot 36, and large arm 37 is fixedly installed on the bottom of bearing sleeve 33, and hydraulic cylinder 38 fixed end is hingedly installed on the outside of large arm 37, in addition, arc slot 36 is provided with two groups, and two groups of arc slot 36 are located on the upper and lower ends of driven gear ring 35 respectively, and ball 34 in single group arc slot 36 is provided with multiple groups, so that large arm 37 rotates more stably, and hydraulic cylinder 38 piston end is hingedly installed on small arm 39, and small arm 39 one end is hingedly installed on the inside of large arm 37 bottom end, and small arm 39 other end is fixedly installed with driving frame 310, and driving frame 310 outside is fixedly installed with second asynchronous motor 311, and second asynchronous motor 311 output shaft outside is fixedly installed with driven frame 312, and driven frame 312 outside is fixedly installed with third asynchronous motor 313, and third asynchronous motor 313 output shaft is fixedly installed on the center outer wall of frame 314 one end, and frame 314 inside is clamped with display screen 315.

[0031] In this embodiment, when the angle of the display screen 315 needs to be adjusted to realize multi-angle display of video content, the first asynchronous motor 31 is started, the rotation of the output shaft of which drives the driving gear 32 to rotate synchronously. When the driving gear 32 rotates, the teeth of the driving gear 32 exert a force on the teeth of the driven gear ring 35. According to the gear meshing transmission principle, the driven gear ring 35 starts to rotate around its axis under the driving of the force. In the rotation process of the driven gear ring 35, the arc-shaped grooves 36 roll along the outer side of the balls 34. Since the multiple groups of balls 34 are distributed in the bearing sleeve 33, and the two arc-shaped grooves 36 are respectively located at the upper and lower ends of the driven gear ring 35, this structure design makes the driven gear ring 35 receive supporting forces from multiple directions during rotation, ensuring the stability of its rotation. Because the bottom of the bearing sleeve 33 is fixedly installed with the large arm 37, the stable rotation of the driven gear ring 35 drives the large arm 37 to make a circular motion, realizing the stable rotation of the large arm 37. When the hydraulic cylinder 38 is started, since the fixed end of the hydraulic cylinder 38 is connected with the outer side of the large arm 37 by hinging, and the piston end is also connected with the small arm 39 by hinging, when the piston makes extension and retraction motion, an acting force is exerted on the small arm 39. According to the lever principle and the characteristics of the hinged structure, the acting force makes the small arm 39 swing around the hinge point relative to the large arm 37, thereby changing the angle of the small arm 39. When the second asynchronous motor 311 on the driving frame 310 is started, the rotation of the output shaft of the second asynchronous motor 311 drives the driven frame 312 to rotate around the axis of the output shaft of the second asynchronous motor 311. When the third asynchronous motor 313 on the driven frame 312 is started, the output shaft of the third asynchronous motor 313 starts to rotate, driving the frame 314 to rotate around the axis of the output shaft of the third asynchronous motor 313. The frame 314 has the display screen 315 clamped inside. The rotation of the frame 314 drives the display screen 315 to rotate together. Through the rotation of the large arm 37, the swing of the small arm 39, and the rotation of the frame 314, the multi-axis motion of the display screen 315 is realized, so that the video content can be displayed to the people in the vehicle from different angles.
