[0030] The present application provides an eccentric rotation mechanism for a display screen, comprising: a first rotation bracket 1 and a second rotation bracket 5;

[0031] The first rotating bracket 1 is fixedly connected to the display screen 2. The connecting portion between the first rotating bracket 1 and the display screen 2 is located at a non-central position on the display screen 2. The first rotating bracket 1 is provided with a first limit block 3 and a second limit block 4.

[0032] The second rotating bracket 5 is rotatably connected to the first rotating bracket 1. The second rotating bracket 5 is provided with a third limit block 6, which is provided between the first limit block 3 and the second limit block 4.

[0033] When the display screen 2 is rotated to the vertical state and the horizontal state, the position height of the upper end thereof is the same.

[0034] For details, please refer to the attached Figure 1 With attached Figure 2 The display screen 2 is a plate-shaped structure, and the first rotating bracket 1 is a plate-shaped structure. The first rotating bracket 1 is arranged on the upper left side of the display screen 2. Its specific position should be determined according to the size of the display screen 2. It should be possible to make the top of the display screen 2 be at the same height position when the display screen 2 is in a vertical state and a horizontal state. The second rotating bracket 5 is arranged on the robot skeleton. The second rotating bracket 5 and the first rotating bracket 1 are rotatably connected. A first limit block 3 and a second limit block 4 are provided on the first rotating bracket 1, and a third limit block 6 is provided on the second rotating bracket 5. The third limit block 6 is arranged between the first limit block 3 and the second limit block 4. The first limit block 3 and the second limit block 4 can play a role of mutual limitation with the third limit block 6.

[0035] Based on the above embodiment, the first rotating bracket 1 is provided with a rotating shaft 7, and the second rotating bracket 5 is provided with a through hole. The rotating shaft 7 passes through the through hole. The through hole is a circular hole, and the diameter of the rotating shaft 7 is less than or equal to the diameter of the through hole.

[0036] Specifically, the first rotating bracket 1 and the rotating shaft 7 are snap-fitted or fixedly connected, and the rotating shaft 7 and the display screen 2 are fixedly connected. It should be noted that the rotating shaft 7 should be a special screw, and a through-hole corresponding to the cross-sectional shape of the rotating shaft 7 is provided on the first rotating bracket 1 to ensure the synchronous rotation of the first rotating bracket 1 and the display screen 2. In addition, a connecting component such as a screw can be provided to ensure the fixed connection between the first rotating bracket 1 and the display screen 2. The through-hole provided on the second rotating bracket 5 should be a circular hole, and the diameter should be slightly larger than or equal to the diameter of the rotating shaft 7 to ensure that the second rotating bracket 5 can rotate relative to the display screen 2.

[0037] On the basis of the above embodiment, a thread is provided on the outer periphery of the end of the rotating shaft 7 away from the first rotating bracket 1 , and the second rotating bracket 5 is rotatably connected to the first rotating bracket 1 via the nut 8 and the rotating shaft 7 .

[0038] Specifically, the rotating shaft 7 is set through the second rotating bracket 5, and the rotating shaft 7 passes through the end of the second rotating bracket 5 and is threadedly connected to the nut 8 to achieve a rotatable connection between the display screen 2 and the second rotating bracket 5, which is convenient for installation and disassembly and replacement.

[0039] Optionally, a through hole may be provided at one end of the rotating shaft 7 passing through the second rotating bracket 5 to achieve the same technical effect through a pin.

[0040] On the basis of the above embodiment, a plurality of spring pieces 9 are provided between the nut 8 and the second rotating bracket 5 , and the spring pieces 9 are sleeved on the outer circumference of the rotating shaft 7 .

[0041] Specifically, at least two springs 9 are provided between the nut 8 and the second rotating bracket 5 , and the springs 9 can increase the damping between the nut 8 and the second rotating bracket 5 , so that the display screen 2 can stop rotating at any angle without the need for additional positioning components.

[0042] Optionally, the spring piece 9 can be made of rubber, which is low in cost and easy to replace.

[0043] On the basis of the above embodiment, the connecting line between the first limiting block 3 and the rotating shaft 7 and the connecting line between the second limiting block 4 and the rotating shaft 7 are perpendicular to each other.

[0044] Specifically, the structural angle obtained by connecting the three components of the first limit block 3, the rotating shaft 7, and the second limit block 4 in sequence is 90°. Without considering the structural size and the collision area, the rotation range of the third limit block 6 is 90° (in fact, since the first limit block 3, the second limit block 4 and the third limit block 6 all have a certain volume, the angle of the first limit block 3, the rotating shaft 7, and the second limit block 4 connected in sequence should be slightly larger than 90°), so that the two extreme positions of the display screen 2 (when the third limit block 6 is in contact with the first limit block 3 and the second limit block 4, they are in the two extreme positions respectively) are that the display screen 2 is in a vertical state and a horizontal state.

[0045] In some embodiments, the first limit block 3, the rotation axis 7 and the second limit block 4 are on the same straight line.

[0046] Specifically, the structural angle obtained by connecting the three components of the first limit block 3, the rotating shaft 7, and the second limit block 4 in sequence is 180°. Without considering the structural size and collision area, the rotation range of the third limit block 6 is 180° (in fact, since the first limit block 3, the second limit block 4 and the third limit block 6 all have a certain volume, the angle of the first limit block 3, the rotating shaft 7, and the second limit block 4 connected in sequence should be slightly larger than 180°), so that the display screen 2 can be turned from the horizontal screen state to the vertical screen whether it is rotated clockwise or counterclockwise (this situation applies to the display screen 2 when the two extreme positions of the third limit block 6 are both vertical screens, and vice versa), avoiding damage caused by improper user operation.

[0047] On the basis of the above embodiment, the second rotating bracket 5 is provided with a hook structure and a supporting and fixing structure, and the supporting and fixing structure is a protrusion with a mounting hole.

[0048] Specifically, the second rotating bracket 5 is provided with a downwardly extending hook structure and a supporting fixing structure. The mounting holes are generally threaded holes, and the robot frame and the second rotating bracket 5 are fixedly connected by screws.

[0049] Optionally, the second rotating bracket 5 can be integrated with the robot frame to improve structural stability.
