The main reason is that the size of the screen is limited by the size of the smart device. In order to solve this problem, people have invented a folding screen and applied it to smart devices. Through the folding design, the smart device can not only meet people's requirements in terms of carrying, but also expand the screen of the smart device by unfolding when needed.

[0018] (3) The utility model ensures the firmness of the connection between the connecting plate and the rotating sleeve rod by setting the first extension plate and the second extension plate, the first fixed plate body on the first extension plate, and the second fixed plate body on the second extension plate.

The structure is ingenious, convenient and practical.

[0023] (8) The utility model provides a positioning rod at the bottom of the rotating plate and a positioning hole corresponding to the positioning rod in the embedding groove, thereby ensuring the accurate installation of the rotating plate and the embedding groove, and ensuring the stability and firmness of the connection between the rotating plate and the connecting plate after being fixed by a locking member.

[0024] (9) The utility model provides a button and a lock hook on the bamboo basket, and a lock slot on the sub-frame. The button is used to control the locking and disengagement of the lock hook and the lock slot. On the one hand, the stability and safety of the sub-frame in the initial position or when it is rotated and reset are ensured. On the other hand, the sub-frame is prevented from automatically popping open under the action of the first damping block and the side guide surface. The force of the sub-frame automatically popping open is overcome by the cooperation of the lock hook and the lock slot, thereby ensuring the safety and stability of the sub-frame in the initial state.

[0025] (10) The utility model provides a pressure inclined surface on the main frame and a side inclined surface on the sub-frame. Through the cooperation of the pressure inclined surface and the side inclined surface, the sub-frame is effectively prevented from having a hard collision with the main frame when rotating and resetting, thereby ensuring the safety and smoothness of the sub-frame during rotation.

[0060] The main frame 6 is provided with a pressing inclined surface 63, and the sub-frame 7 is provided with a side inclined surface 71 corresponding to the pressing inclined surface 63. After the sub-frame 7 is rotated to be flush with the upper end surface of the main frame 6, the side inclined surface 71 on the sub-frame 7 presses against the pressing inclined surface 63 of the main frame 6.

[0061] Working principle of the utility model: During the installation process of the utility model, a rotating component 1 with a synchronous transmission component 2 and a rotating component 1 without a synchronous transmission component 2 are first installed in the installation base 10. The rotating component 1 with the synchronous transmission component 2 drives the corresponding long shaft 13 to rotate during the rotation of the rotating plate 3. The long shaft 13 drives the first transmission block 21 and the second transmission block 23 to rotate. The first driving curved surface 211 on the first transmission block 21 acts on the second driving curved surface 221 on the synchronous transmission block 22. Therefore, the synchronous transmission block 22 slides on the two long shafts 13 under the drive of the first transmission block 21. At the same time, the fourth driving surface 231 on the second transmission block 23 acts on the third driving curved surface 222 of the synchronous transmission block 22. When the first driving curved surface 211 is completely fitted with the second driving curved surface 221, the third driving curved surface 222 and the fourth driving curved surface 231 are only partially pressed. Similarly, when the third driving curved surface 211 is fully fitted with the second driving curved surface 221, the third driving curved surface 222 and the fourth driving curved surface 231 are only partially pressed. When 222 and the fourth driving curved surface 231 are completely fitted together, the first driving curved surface 211 and the second driving curved surface 221 are only partially pressed against each other, so the synchronous transmission block 22 slides between the first transmission block 21 and the second transmission block 23 under the combined drive of the first transmission block 21 and the second transmission block 23, thereby driving the other long axis 13 to rotate, and driving the rotating sleeve rod 12 on the other long axis 13 and the rotating plate 3 on the rotating sleeve rod 12 to rotate, thereby realizing the synchronous rotation of each rotating plate 3 on the same rotating component 1, and each different rotating component 1 is synchronously rotated through the connecting plate 5, the rotating plate 3 on one side of each rotating component 1 is fixed on the same connecting plate 5, and the rotating plate 3 on the other side of each rotating component 1 is also fixed on the same connecting plate 5, the two connecting plates 5 are located on both sides of the mounting base 10 and are arranged in parallel, and the two connecting plates 5 are respectively fixedly connected to the main frame 6 and the sub-frame 7, and the main frame 6 and the sub-frame 7 are electrically connected through the FPC soft board 4;

[0062] The cooperation of the first damping block 121 and the first damping groove 141 enables the sub-frame 7 to automatically pop open after being unlocked. The cooperation of the first damping block 121 and the second damping groove 143 enables the sub-frame 7 to open to a card point at an angle of 180° with the main frame 6. The cooperation of the second damping block 122 and the third damping groove 161 enables the sub-frame 7 to open to a card point at an angle of 120° with the main frame 6.

[0063] When the operator presses the button 62, the lock hook 63 is disengaged from the lock groove 72. At this time, the first damping block 121 is located on the side guide surface 142. After unlocking, the first damping block 121 slides into the first damping groove 141 through the guidance of the side guide surface 142. When the first damping block 121 slides into the first damping groove 141, the angle between the sub-frame 7 and the main frame 6 is 70°, and it can be stuck at the 70° position without external force. When external force is applied, the first damping block 121 is disengaged from the first damping groove 141, and the second damping block 122 slides into the second damping groove 143, that is, the manual opening to the main frame 6 and the sub-frame 7. When the angle is greater than 100°, when the second damping block 122 automatically slides into the second damping groove 143, the clamps of the main frame 6 and the sub-frame 7 will be maintained at 120°. When the second damping block 122 is disengaged from the second damping groove 143 and the first damping block 121 enters the third damping groove 161, that is, when the angle between the main frame 6 and the sub-frame 7 is greater than 160°, after the first damping block 121 automatically slides into the third damping groove 161, the angle between the main frame 6 and the sub-frame 7 will be stuck at 180°, thereby realizing the hovering of the rotating plate 3, the connecting plate 5 fixed on the rotating plate 3, and the sub-frame 7 fixed on the connecting plate 5 at different angles.

[0064] Compared with the existing hinge, the utility model realizes the synchronous rotation between the two long shafts 13 by setting the first transmission block 21, the synchronous transmission block 22 and the second transmission block 23 on the long shaft 13, replacing the problem of realizing the synchronous transmission between the two long shafts 13 by a gear set or a gear pair in the prior art. By setting the first transmission block 21, the synchronous transmission block 22 and the second transmission block 23 on the long shaft 13, the installation space can be greatly saved in the installation base 10, avoiding the problem of squeezing and collision between the hinge mechanism and the folding part due to the small space in the prior art, ensuring the high efficiency and safety of the rotation of each part, thereby ensuring the safety and smoothness between the main frame 6 and the sub-frame 7, and ensuring the overall service life of the smart device, with ingenious structure, stable and practical.
