[0035] Refer to Figure 1 and Figure 2, an embodiment of the present application provides a flip screen device, including a screen mechanism 1, a driving mechanism 2 and a driven mechanism 3. Among them, the screen mechanism 1 includes a mounting base 11 and a screen assembly 12. The screen assembly 12 is rotatably arranged on the mounting base 11, so that the screen assembly 12 can be separated from the mounting base 11 when needed and fit with the mounting base 11 when not in use, to protect the screen assembly 12 and solve the problem of aging of the screen assembly 12 due to long-term exposure to the outside. The driving mechanism 2 is used to drive the screen assembly 12 to rotate, so that the screen assembly 12 can reciprocally rotate between the open position and the closed position and can hover at any position between the open position and the closed position, which is convenient for the operator to use. The driven mechanism 3 is used to enhance the stability of the screen assembly 12 on the mounting base 11, assist the screen assembly 12 to rotate, and enhance the stability of the screen assembly 12 during rotation.

[0036] Specifically, the mounting base 11 has a mounting surface for installation and a fitting surface arranged opposite to the mounting surface, and the mounting surface is parallel to the fitting surface. The screen assembly 12 has a mounting shaft 13, and the screen assembly 12 is rotatably connected to the mounting base 11 through the mounting shaft 13, and the screen assembly 12 has a display surface. When the screen assembly 12 is in the closed position, the display surface of the screen assembly 12 fits on the fitting surface of the mounting base 11 and is parallel to the fitting surface of the mounting base 11, so as to protect the display surface of the screen assembly 12. When the screen assembly 12 is in the open position, the angle between the display surface of the screen assembly 12 and the fitting surface of the mounting base 11 is greater than or equal to 90° and less than 140°, so that the user can view the content on the display surface of the screen assembly 12.

[0037] Refer to Figures 1 - 3The driving mechanism 2 includes a driver 21 and a gear assembly 22. The driver 21 and the gear assembly 22 are spaced apart in the mounting seat 11 along an axial direction perpendicular to the mounting shaft 13. The driver 21 is connected to one axial end of the mounting shaft 13 through the gear assembly 22 to drive the screen assembly 12 to rotate so that the screen assembly 12 can fit into or separate from the mounting seat 11. Specifically, the gear assembly 22 has an input end and an output end arranged vertically, the driver 21 is a driving motor, the motor shaft of the driving motor is connected to the input end of the gear assembly 22, and the output end of the gear assembly 22 is provided with a first rotating shaft 23, and the first rotating shaft 23 is coaxially connected to the installation shaft 13. When the driving motor is working, it can drive its motor shaft to rotate, so that the gear assembly 22 drives the first rotating shaft 23 and the installation shaft 13 to rotate, so that the screen assembly 12 can be attached to or separated from the mounting seat 11. When the screen assembly 12 is in the open position, the screen assembly 12 is separated from the mounting seat 11, so that the user can view the content on the display surface of the screen assembly 12. When the screen assembly 12 is in the closed position, the screen assembly 12 is attached to the mounting seat 11, so that the display surface of the screen assembly 12 is protected. In addition, the driving mechanism 2 also includes a circuit board 24, and the driver 21 is electrically connected to the circuit board 24 to realize the control of the driver 21 through the circuit board 24.

[0038] The driven mechanism 3 is arranged in the mounting seat 11 and is transmission-connected to the other axial side of the mounting shaft 13. Specifically, the driven mechanism 3 includes a coupling, and the mounting shaft 13 is transmission-connected to the coupling. Compared with the gear connection, the coupling can directly connect the mounting shaft 13 with the driven mechanism 3, thereby reducing noise while ensuring the stability of the mounting shaft 13. That is, relative to the gear transmission structure, the driven mechanism 3 with the coupling is simple and efficient in structure, and there is no noise from the gear meshing process in the gear transmission structure, which can effectively reduce noise. More specifically, the coupling includes a second rotating shaft 31, and the side of the mounting shaft 13 facing away from the first rotating shaft 23 is connected to the second rotating shaft 31.

[0039] The flip screen device of the present application drives the screen assembly 12 to rotate through the driver 21, so that the screen assembly 12 can be separated from the mounting base 11 when needed, so that the user can view the content on the display surface of the screen assembly 12, and fit with the mounting base 11 when not in use, so as to protect the screen assembly 12, so that the display surface of the screen assembly 12 will not be exposed to the outside for a long time, reducing the possibility of damage. At the same time, by reasonably arranging the driving mechanism 2, the driver 21 and the gear assembly 22 of the driving mechanism 2 are arranged at an axial interval perpendicular to the mounting axis 13, which can effectively reduce the axial size of the mounting base 11 along the mounting axis 13, thereby saving the occupied space of the device.

[0040] See also Figures 2 - 3In one embodiment, the mounting shaft 13 is provided with a mounting channel extending through the mounting shaft 13 in the axial direction thereof, and the gear assembly 22 is provided with a first rotating shaft 23, which is inserted into and fixed inside one axial end of the mounting channel to increase the contact area between the gear assembly 22 and the mounting shaft 13, thereby increasing the connection stability between the gear assembly 22 and the mounting shaft 13. The driven mechanism 3 includes a second rotating shaft 31, which is inserted into and fixed inside the other axial end of the mounting channel to increase the contact area between the driven mechanism 3 and the mounting shaft 13, thereby increasing the connection stability between the driven mechanism 3 and the mounting shaft 13.

[0041] In one embodiment, a mounting groove 14 is provided on the mounting seat 11, and the mounting shaft 13 is rotatably disposed in the mounting groove 14 to save space occupied by the device. Specifically, the mounting seat 11 has a mounting surface for mounting and fixing and a fitting surface disposed away from the mounting surface, and also has a connecting surface connecting the mounting surface and the fitting surface. The mounting groove 14 opens on the connecting surface and extends a distance toward the inside of the mounting seat 11, and the mounting groove 14 penetrates the mounting surface and the fitting surface. The mounting shaft 13 is disposed in the mounting groove 14, and the axial ends of the mounting shaft 13 are respectively connected to the first rotating shaft 23 and the second rotating shaft. When the driver 21 drives the first rotating shaft 23 to rotate through the gear, the mounting shaft 13 rotates in the mounting groove 14 accordingly, and at the same time drives the screen assembly 12 and the second rotating shaft 31 to rotate.

[0042] See also Figure 3 In one embodiment, the mounting base 11 includes a base 111 and a top cover 112, the base 111 is provided with a seating groove, the driving mechanism and the driven mechanism 3 are both arranged in the seating groove, the top cover 112 is arranged on the base 111, and the orthographic projection of the top cover 112 on the base 111 covers the orthographic projection of the seating groove on the base 111.

[0043] Specifically, the mounting surface and the fitting surface are respectively located on the base 111 and the top cover 112. A placement groove is provided on the side of the base 111 away from the mounting surface, and the top cover 112 covers the notch of the placement groove to shield and protect the driving mechanism and the driven mechanism 3 in the placement groove. More specifically, an auxiliary groove is provided on the side of the top cover 112 away from the fitting surface, and a receiving space for accommodating the driving mechanism and the driven mechanism 3 is provided in the mounting seat 11, and the receiving space is surrounded by the placement groove and the auxiliary groove. By making the top cover 112 also accommodate part of the driving mechanism and the driven mechanism 3, the driving mechanism and the driven mechanism 3 in the base 111 can be partially located outside the placement groove. Compared with the setting method in which the driving mechanism and the driven mechanism 3 are all located in the placement groove, the setting method in which the driving mechanism and the driven mechanism 3 are partially located outside the placement groove is more convenient for the installer to install the driving mechanism and the driven mechanism 3.

[0044] See alsoFigures 1 - 3 In one embodiment, the flip screen device further includes a first shock absorber 4 and a second shock absorber 5. The first shock absorber 4 is disposed between the mounting base 11 and the driving mechanism 2 to reduce the resonance generated when the driving mechanism 2 operates and reduce noise. The second shock absorber 5 is disposed between the mounting base 11 and the driven mechanism 3 to enhance the buffering and shock absorption effect of the driven mechanism 3 within the mounting base 11 and reduce the resonance generated when the screen assembly 12 rotates and reduce noise.

[0045] Specifically, the driving mechanism 2 has a first outer shell. The first shock absorber 4 is passed through the first outer shell and abuts against two opposite side surfaces of the first outer shell, so that the first shock absorber 4 not only functions to shock-absorb the driving mechanism but also functions to mount the driving mechanism on the mounting base 11. The driven mechanism 3 has a second outer shell. The second shock absorber 5 is passed through the second outer shell and abuts against two opposite side surfaces of the second outer shell, so that the second shock absorber 5 not only functions to shock-absorb the driven mechanism 3 but also functions to mount the driven mechanism 3 on the mounting base 11.

[0046] Refer to Figure 1 、 Figure 3 and Figure 4 In one embodiment, the first shock absorber 4 includes a first shock-absorbing column 41 and two first shock pads 42. The first shock-absorbing column 41 is passed through the outer shell along the axial direction perpendicular to the mounting shaft 13. The two first shock pads 42 are both disposed on the first shock-absorbing column 41 and respectively abut against two opposite side surfaces of the first outer shell. Specifically, a first groove is provided on the first outer shell, and a first connecting plate parallel to the mounting surface is provided in the first groove. The first shock-absorbing column 41 is passed through the first connecting plate along the axial direction perpendicular to the mounting shaft 13. The two first shock pads 42 are respectively disposed at the two axial ends of the first shock-absorbing column 41 and respectively abut against two opposite side surfaces of the first connecting plate.

[0047] In one embodiment, the second shock absorber 5 includes a second shock-absorbing column and two second shock pads. The second shock-absorbing column is passed through the second outer shell along the axial direction perpendicular to the mounting shaft 13.
