[0030] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] The embodiment of the present invention provides a double-acting rotating mechanism, including a rotating shaft body, a torque assembly and an electric drive assembly. The rotating shaft body is a rotating structure, and the rotating shaft structure is driven to rotate manually or electrically, so as to drive the device to be rotated to rotate a set angle. During manual rotation and electric rotation, damping is provided by a device integrated inside the mechanism, and there is no need to provide a damping device separately, thereby effectively optimizing the structure of the mechanism.

[0032] like Figures 1 to 4 As shown, in the embodiment of the present invention, one end of the shaft body 10 is used to connect the device 40 to be rotated; the torsion assembly 20 includes a first torsion structure 21 and a second torsion structure 22, the first torsion structure 21 is connected to the other end of the shaft body 10, and is used to rotate synchronously with the shaft body 10, and the second torsion structure 22 is sleeved on the circumference of the shaft body 10; the electric drive assembly 30 is connected to the second torsion structure 22, and is used to drive the second torsion structure 22 to rotate; for example, the device 40 to be rotated is a display screen of an electronic device, and in order to increase the diversity of the rotation of the display screen, the display screen can adopt a double-action mode, that is, manual rotation and electric rotation. In the embodiment of the present invention, under the action of the first torsion structure 21 and the second torsion structure 22, torque can be provided for rotation, thereby providing a damping effect during the double-action process.

[0033] Among them, the torque between the second torsion structure 22 and the shaft body 10 is greater than the gravity of the device 40 to be rotated. Based on this, when manually driven, the shaft body 10 used for manual driving rotates. At this time, the electric drive component 30 limits the second torsion structure 22 to rotate, and as the driving force increases, the shaft body 10 and the second torsion structure 22 rotate relative to each other, thereby generating a torque, which provides damping for manual rotation. When electrically driven, the electric drive component 30 drives the second torsion structure 22 to rotate. Since the torque between the second torsion structure 22 and the shaft body 10 is greater than the gravity of the device 40 to be rotated, the second torsion structure 22 rotates synchronously with the shaft body 10. As the shaft body 10 rotates, the first torsion structure 21 generates a torque, which provides damping for electric rotation.

[0034] Continue to refer Figures 1 to 4 As shown, in the embodiment of the present invention, the shaft body 10 also includes a base 11, and a mounting groove 12 is provided on the base 11. The outer side of the shaft body 10 is sleeved with a bearing 13. The shaft body 10 and the bearing 13 are arranged in the mounting groove 12, and one end of the shaft body 10 passes through the bottom of the mounting groove 12. When the double-acting rotating mechanism is connected to the electronic device, it can be connected to the housing or mounting structure of the electronic device through the base 11. Among them, the double-acting rotating mechanism also includes a shaft connecting column 50 with a set height, one end of the shaft connecting column 50 is connected to one end of the shaft body 10, and the other end is connected to the device 40 to be rotated. The shaft connecting column 50 has a set height, and the device 40 to be rotated can be set at a certain height, and the shaft connecting column 50 can transmit driving force during manual rotation operation.

[0035] Furthermore, a bearing 13 is sleeved on the outer side of the shaft body 10 . The bearing 13 is disposed in the mounting groove 12 . The shaft body 10 can freely rotate relative to the base 11 through the bearing 13 .

[0036] In the embodiment of the present invention, the first torsion structure 21 and the second torsion structure 22 are integrated on the shaft body 10. Compared with the structure of the traditional independent damper, the integrated structure occupies less space while satisfying the damping effect. For example, the first torsion structure 21 includes a torsion plate 211 and a torsion nut 212; the torsion plate 211 is sleeved on the circumference of the shaft body 10, and the torsion plate 211 and the shaft body 10 are connected by a limiting structure, the torsion nut 212 is connected to the other end of the shaft body 10, and the torsion plate 211 and the torsion nut 212 rotate synchronously with the shaft body 10.

[0037] For example, Figure 4As shown, a horizontal section is set on the surface of the shaft body 10, so that the cross-sectional shape of this part of the shaft body 10 is non-circular. Similarly, the sleeve hole in the middle of the torsion plate 211 is also non-circular, and its cross-sectional shape is the same as the cross-sectional shape of the shaft body 10. After the torsion plate 211 is sleeved on the shaft body 10, the two will not produce relative rotation, thereby achieving the purpose of limiting. In addition, the number of torsion plates 211 can be one or more.

[0038] In the embodiment of the present invention, the limiting structure is not limited thereto, and it may also be other limiting structures, such as a snap-fit ​​or auxiliary connection structure.

[0039] For example, the second torsion structure 22 includes a flange 221, which is connected to the electric drive assembly 30; the flange 221 is sleeved on the circumference of the shaft body 10, and the torsion between the flange 221 and the shaft body 10 is greater than the gravity of the device 40 to be rotated. Figure 4 As shown, the shaft body 10 includes an annular circumferential surface (a portion without a horizontal section), that is, the cross-section of this partial structure is circular, and the inner wall of the sleeve hole of the flange 221 fits with the circumferential surface of the shaft body 10 and can rotate relatively.

[0040] Under the condition that the torque between the rotating shaft body 10 is greater than the gravity of the device to be rotated 40. When manually rotating, the rotating shaft body 10 rotates, and the flange 221 cannot rotate under the action of the electric drive assembly 30, and a torque is generated between the rotating shaft body 10 and the flange 221. When electrically rotating, under the action of the electric drive assembly 30, the flange 221 rotates, and the rotating shaft body 10 and the flange 221 rotate synchronously. At this time, the torsion plate 211 will also rotate with the rotating shaft body 10, and the torsion plate 211 and the structure superimposed thereon will generate a torque.

[0041] Continue to refer Figures 1 to 4 As shown, for example, the electric drive assembly 30 includes a bearing inner ring 31, a bearing outer ring 32 and a drive motor module 33; the bearing outer ring 32 is sleeved on the outer side of the bearing inner ring 31 and is overlapped with the flange 221, the bearing outer ring 32 is fixedly connected to the base 11, and the bearing inner ring 31 is connected to the flange 221; the inner ring of the bearing inner ring 31 is provided with annular teeth, the drive motor module 33 is connected to the bearing outer ring 32, and the output shaft of the drive motor module 33 is connected to the drive gear, and the drive gear is meshed with the annular teeth.

[0042] The output shaft of the drive motor module 33 rotates forward or reversely to control the forward or reverse rotation of the annular gear, so that the rotation direction of the device to be rotated 40 can be adjusted along two rotation directions. For example, the mechanism includes multiple groups of drive motor modules 33, and the multiple groups of drive motor modules 33 are evenly distributed along the circumference of the inner ring 31 of the bearing. As shown in the figure, the mechanism includes two groups of drive motor modules 33, and the two groups of drive motor modules 33 rotate synchronously to achieve simultaneous driving of the annular gear. By setting a larger number of drive motor module groups, the stability and accuracy of the annular gear drive can be improved.

[0043] Continue to refer Figures 1 to 4 As shown, in the embodiment of the present invention, the mechanism further includes an angle measuring component 60; the angle measuring component 60 is used to measure the rotation angle of the shaft body 10. The rotation angle information of the shaft body 10 can be obtained through the angle measuring component 60, and the rotation angle information can be sent to the control device, and the rotation angle information can be fed back to the user through the control device. In the case of electric rotation, it can be determined when to stop the rotation according to the information fed back by the angle measuring component 60.

[0044] For example, the angle measurement assembly 60 includes an angle counter gear 61 and an angle counter 62; the angle counter gear 61 includes a sleeve hole in the middle part, the angle counter gear 61 is sleeved on the circumferential surface of the rotating shaft body 10 through the sleeve hole, and the angle counter gear 61 is connected to the rotating shaft body 10 through a limiting structure; the angle counter 62 is arranged on the bearing outer ring 32, and the angle counter 62 includes a counting gear, and the counting gear is meshed with the angle counter gear 61.

[0045] For example, the limiting method between the angle counter gear 61 and the shaft body 10 is the same as the limiting method between the torque plate 211 and the shaft body 10, or other limiting methods such as snap-fit ​​or auxiliary connection structures may be used.

[0046] When the angle measuring assembly 60 is in use, the angle counter gear 61 rotates synchronously with the shaft body 10 , thereby driving the angle counter 62 to rotate. The angle counter 62 determines the rotation angle of the shaft body 10 according to the number of rotations.

[0047] In the embodiment of the present invention, the bearing 13, the flange 221, the angle counter gear 61, the torque plate 211 and the torque nut 212 are sequentially stacked on the circumferential surface of the shaft body 10 from one end to the other end of the shaft body 10. The torque plate 211 is stacked between the angle counter gear 61 and the torque nut 212, and the torque plate 211 can generate torque when it rotates.

[0048] like Figure 5As shown, an embodiment of the present invention further provides an electronic terminal device, including the above-mentioned double-action rotating mechanism, the electronic terminal device includes a host and a display screen, and the double-action rotating mechanism is arranged in the host. For example, the electronic terminal device is a conference machine, and the double-action rotating structure, except for the shaft connecting column 50, is arranged in the body structure of the conference machine, and the shaft connecting column 50 is connected to the display screen, and the display screen is set at a certain height. When the user uses it, the display screen can be rotated manually or electrically.

[0049] The present invention provides a double-acting rotating mechanism and an electronic terminal device, which can realize manual rotation and electric rotation when in use. When manually rotating, the shaft body 10 rotates, and the second torsion structure 22 does not rotate synchronously under the action of the electric drive assembly 30, which plays a damping role. When electrically driven, since the torsion between the second torsion structure 22 and the shaft body 10 is greater than the gravity of the device 40 to be rotated, the second torsion structure 22 drives the shaft body 10 to rotate under the action of the torsion, and the torsion between the second torsion structure 22 and the shaft body 10 plays a damping role. The technical solution of the present invention can realize the functions of electric rotation and manual rotation, and the two rotation modes are independently operated without interfering with each other. In the operation process, there is no need to install a damper independently, and damping is achieved by the structure itself. The structure is simple and easy to implement, and the cost is lower.
