The central axis of the second rotating shaft 221 is parallel to the central axis of the first rotating shaft 211. The second rotating shaft 221 can move along Rotate in the first direction. The rotational movement of the second rotating shaft 221 in the first direction can also be understood as the swinging movement of the display screen bracket 200 in the first direction, which is equivalent to the leftward and rightward swinging motion of the display screen bracket 200 described above. The other end of the link mechanism 230 is connected to the second rotating shaft 221 and can rotate together with the rotational motion of the second rotating shaft 221 . Specifically, one end of the third rod 2331 and the fourth rod 2332 in the link mechanism 230 away from the balance rod 232 is connected to the second rotating shaft 221 . In other words, the link mechanism 230 can be driven by the second rotating shaft 221 to perform rotational movement in the first direction. Under this setting, the display screen 100 and the link mechanism 230 can be linked. That is, when the link mechanism 230 is driven by the second rotating shaft 221 to rotate in the first direction, the display screen 100 can be driven by the link mechanism 230 to rotate in the first direction.

The second motor 223 includes a second motor body 2231 and a second power shaft 2232 connected to the second motor body 2231. The second power shaft 2232 is coaxially connected to the second rotating shaft 221, and the second rotating shaft 221 is rotationally connected to the second connection base. 222, and the second rotating shaft 221 is connected to the link mechanism 230.

When the link mechanism 230 rotates along the first direction, it drives the display screen 100 to rotate, so that the display screen 100 can face different directions. The rotational motion of the display screen 100 in the first direction can also be understood as the swinging motion in the first direction, which is equivalent to the swinging motion of the display screen 100 to the left and right.

It can be understood that by providing the second motor 223, the second rotating shaft mechanism 220 can convert electrical energy into mechanical energy to automate the rotation of the second rotating shaft 221, thereby driving the display screen 100 to automatically rotate in the first direction.

Based on the above description, it should be understood that the second rotating shaft 221 drives the link mechanism 230 to rotate, thereby driving the display screen 100 to rotate, thereby increasing the rotation angle of the display screen 100 in the first direction. That is, on the basis that the first rotating shaft 211 rotates in the first direction to rotate the display screen 100, the second rotating shaft 221 rotates in the first direction to cause the display screen 100 to perform rotational motion, which can also provide a rotation angle for the display screen 100 again. Thereby, the rotation angle of the display screen 100 in the first direction is increased.

Variety.

Under this setting, the first link group 231 can drive the display screen 100 to move in the second direction and the third direction. Specifically, as the angle between the first link group 231 and the second link group 233 becomes smaller, that is, the quadrilateral area of the first parallelogram mechanism 2301 becomes smaller, the movement of the display bracket 200 is 200 is contracted and moved close to the external support body, and the display bracket 200 is swinging upward or downward in the third direction. When the quadrilateral area of the first parallelogram mechanism 2301 becomes larger, the movement of the display screen bracket 200 is the movement of the display screen bracket 200 extending away from the external support, and the display screen bracket 200 moves upward or downward in the third direction.

That is to say, the relative position of the second connecting rod group 233 and the second connecting seat 222 changes, and the relative position of the first connecting rod group 231 relative to the second connecting rod group 233 changes.

For example, when the areas of the first parallelogram mechanism 2301 and the second parallelogram mechanism 2302 become smaller, the movement of the display screen bracket 200 is the moving action of the display screen bracket 200 contracting and approaching the external support body. When the areas of the first parallelogram mechanism 2301 and the second parallelogram mechanism 2302 become larger, the movement of the display screen bracket 200 is the movement of the display screen bracket 200 extending away from the external support.

It should be noted that if the lengths of the swingable sides of the first parallelogram mechanism 2301 and the second parallelogram mechanism 2302 are different, the contraction and extension actions of the display screen bracket 200 can also drive the display screen 100 to move in the second direction. The aforementioned two embodiments are only two motion situations of the display screen bracket 200 , the changes in the quadrilateral shape of the first parallelogram mechanism 2301 , the changes in the quadrilateral shape of the second parallelogram mechanism 2302 , the rotation of the first rotating shaft 211 and the second The rotation of the rotating shaft 221 moves independently, and the display screen bracket 200 can perform different movements according to different scenarios.
