[0005] The electronic device includes a main body, a first rotating structure, and a clutch structure. The main body includes a display portion and a host portion. The first rotating structure is fixed to the host portion and includes a first power component and a first connecting component. The power end of the first power component is connected to the display portion via the first connecting component to drive the display portion to rotate. The clutch structure is disposed between the first power component and the first connecting component, and has a first state and a second state. In the first state, the clutch structure cuts off the power transmission between the first power component and the first connecting component, allowing the first connecting component to rotate relative to the first power component. In the second state, the clutch structure restores the power transmission between the first power component and the first connecting component, allowing the first power component to drive the first connecting component to rotate.

The power end of the first power element is connected to the driving gear via the worm, and the first driven gear is connected to the first connecting element via the friction resistance element. In a first state, the worm and the driving gear are locked together, and the locking force between the worm and the first driving gear is greater than the friction force between the friction resistance element and the first connecting element, so as to cut off the power transmission between the first power element and the first connecting element. In a second state, the worm and the driving gear are released from the locking engagement, so as to enable the first power element to drive the first connecting element to rotate.

[0008] In one possible implementation of this application, the first gear set further includes a second driven wheel, which is connected to the first connecting member in a transmission manner. The electronic device further includes a first detection element, which is disposed on the second driven wheel to detect the rotation angle of the power end of the first power member.

[0010] In one possible implementation of this application, the electronic device further includes a second rotating structure, which includes a second power member and a second connecting member. The power end of the second power member is connected to the second connecting member for driving the second connecting member to rotate. One of the second power member and the second connecting member is fixedly connected to the first connecting member, and the other of the second power member and the second connecting member is fixedly connected to the display part for connecting the first connecting member to the display part. The rotation axis of the power end of the first power member is at an angle to the rotation axis of the power end of the second power member.

[0011] In one possible implementation of this application, the second rotating structure further includes a housing and a second detection element. Both the second power element and the second detection element are disposed within the housing, and the second detection element is electrically connected to the second power element to detect the rotation angle of the power end on the second power element.

[0012] In one possible implementation of this application, the second rotating structure further includes a signal transmission line, one end of which is electrically connected to the second detection element, and the other end of which is electrically connected to the host unit. The signal transmission line is configured via a second connector to transmit the detection information of the second detection element to the host unit.

[0013] In one possible implementation of this application, the second rotating structure further includes a second gear set, the second connecting member is a connecting shaft, and the power end of the second power member is connected to the second connecting member via the second gear set, so as to make the rotation axis of the power end of the second power member parallel to the rotation axis of the second connecting member.

[0014] In one possible implementation of this application, the second rotating structure includes a second base, and the second connector is rotatably disposed on the second base; the electronic device further includes a second damping structure disposed between the second connector and the second base to increase the frictional force between the second connector and the second base.

[0032] With the rapid development of electronic devices, such as laptops, tablets, and all-in-one computers, they have become essential tools for people's daily work and life. However, the rotation of the display portion in these devices lacks flexibility and cannot adapt to the needs of different scenarios. The electronic device provided in this application can be a laptop, tablet, all-in-one computer, or similar device.

[0033] This application provides an electronic device, with reference to... Figures 1 to 5 and Figure 9 The electronic device includes a main body, a first rotating structure 1, and a clutch structure 2. The main body includes a display portion 6 and a host portion 7. The first rotating structure 1 is fixed to the host portion 7 and includes a first power component 11 and a first connecting component 12. The power end of the first power component 11 is connected to the display portion 6 via the first connecting component 12 to drive the display portion 6 to rotate. The clutch structure 2 is disposed between the first power component 11 and the first connecting component 12, and has a first state and a second state. In the first state, the clutch structure 2 cuts off the power transmission between the first power component 11 and the first connecting component 12 to allow the first connecting component 12 to rotate relative to the first power component 11. In the second state, the clutch structure 2 restores the power transmission between the first power component 11 and the first connecting component 12 to allow the first power component 11 to drive the first connecting component 12 to rotate.

[0034] In this embodiment, the device body refers to the physical carrier and frame of the electronic device. The device body includes a display part 6 and a host part 7; the display part 6 may include a screen, touch screen, etc.; the host part 7 may include a computing unit such as a CPU, motherboard, and battery.

[0035] In the embodiments of this application, reference is made to Figure 9 The first rotating structure 1 is a structure that enables the display portion 6 to rotate horizontally relative to the host portion 7. Horizontal rotation refers to the rotation of the display portion 6 within a horizontal plane parallel to the upper surface of the host portion 7 after it has been opened to a certain angle relative to the host portion 7. With the host portion 7 remaining stationary, the display portion 6 rotates about an axis that forms an angle with the upper surface of the host portion 7. This rotation can change the relative orientation between the display portion 6 and the host portion 7, so that there is an angle between the extension direction of the length of the display portion 6 and the extension direction of the length of the host portion 7, or form any angle between 0° and 180°.

[0036] In this embodiment, the first power component 11 can provide the driving force for rotational power. The first power component 11 can be a stepper motor, a servo motor, or a coreless motor, and may also include a reduction gearbox 134 to provide the torque.

[0037] For example, the first power component 11 can be a coreless motor, which can output a large torque. A magnetic structure and a damper can be added to the coreless motor. Through the control performance and large torque of the coreless motor body, the minimum holding force is increased. The damper can make the rotational force conversion smoother and more compliant, and can compensate for the shortcomings of the coreless motor in micro-torque control, thereby making the rotation process smoother and reducing the occurrence of two-stage forces.

[0038] In this embodiment, the first connector 12 is connected to the display portion 6 and transmits the power of the first power member 11 to the display portion 6. The first connector 12 can be a gear, a shaft, a connecting rod, or a mounting base, etc.

[0039] In this embodiment, the clutch structure 2 is disposed between the first power member 11 and the first connecting member 12, enabling the clutch structure 2 to control the association between the first power member 11 and the display part 6. In the first state, the clutch structure 2 cuts off the power transmission path. At this time, the rotation of the first power member 11 and the first connecting member 12 is decoupled, allowing the first connecting member 12 to rotate independently. The user can manually rotate the display part 6 without being affected by the internal resistance of the motor (such as gear meshing friction and electromagnetic resistance of the motor), and without causing damage to the internal rotation of the gears when the user manually rotates the display part 6, thereby achieving effortless and smooth manual operation.

[0040] In the second state, the clutch structure 2 restores the power transmission path. At this time, the first power component 11 and the first connecting component 12 are rigidly connected or connected through the transmission component. The torque output by the motor can be effectively transmitted to the display part 6 to realize electric control rotation.

[0041] In the electronic device of this application embodiment, since the first rotating structure 1 is fixed to the main unit 7, the first rotating structure 1 includes a first power member 11 and a first connecting member 12. The power end of the first power member 11 is connected to the display unit 6 through the first connecting member 12. Therefore, the power end of the first power member 11 can drive the display unit 6 to rotate relative to the main unit 7. Since the clutch structure 2 is disposed between the first power member 11 and the first connecting member 12, and the clutch structure 2 has a first state and a second state, when the clutch structure 2 is in the first state, the clutch structure 2 cuts off the power transmission between the first power member 11 and the first connecting member 12, that is, the torque transmission path between the first power member 11 and the first connecting member 12, so that the first connecting member 12 can rotate freely independently of the first power member 11. Since the first connecting member 12 is connected to the display unit 6, in the first state of the clutch structure 2, the display unit 6 can rotate independently of the first power member 11. At this time, if the user applies external force to the display unit 6, the display unit 6 will rotate smoothly around the rotating structure, that is, the user can rotate the display unit 6 manually. In the second state, the clutch structure 2 restores the mechanical connection between the first power component 11 and the first connecting component 12. The rotational torque output by the first power component 11 can be transmitted to the first connecting component 12 through the clutch structure 2, allowing the first connecting component 12 to rotate under the drive of the output shaft of the first power component 11. At this time, the first power component 11 becomes the power source, controlling the rotation of the display part 6. Thus, by changing the state of the clutch structure 2, the rotation of the display part 6 can be switched between manual control and control by the first power component 11, thereby flexibly adapting to different needs or application scenarios.

[0042] In some possible embodiments of this application, reference is made to Figure 3 , Figure 4 and Figure 5 The first rotating structure 1 also includes a first gear set 13, and the power end of the first power member 11 is connected to the first connecting member 12 through the first gear set 13.

[0043] In this embodiment of the application, the first gear set 13 may include at least one gear, and the first gear set 13 may also include multiple reduction gears 134. The multiple reduction gears 134 mesh with each other, which can reduce the speed of the output shaft and amplify the output torque.

[0044] In the electronic device of this application embodiment, since the power end of the first power member 11 is connected to the first connector 12 through the first gear set 13, the first gear set 13 enables the first power member 11 to output greater torque to drive the display part 6, while improving the accuracy and stability of the rotation control of the display part 6; the gear transmission of the first gear set 13 also optimizes the flexibility of the motor layout. The first gear set 13 works in conjunction with the clutch structure 2, and amplifies the resistance in reverse through the gear ratio during manual operation, reducing the situation where the first power member 11 is accidentally forcibly reversed, thereby enhancing reliability and protection.

[0045] In some possible embodiments of this application, reference is made to Figure 3 , Figure 4 and Figure 5 The first gear set 13 includes a driving gear 131 and a driven gear 132 connected by transmission. The clutch structure 2 includes a worm 21 and a friction resistance element 22. The power end of the first power element 11 is connected to the driving gear 131 by transmission through the worm 21, and the first driven gear 132 is connected to the first connecting member 12 by transmission through the friction resistance element 22. In the first state, the worm 21 is locked to the driving gear 131, and the locking force between the worm 21 and the first driving gear 131 is greater than the friction force between the friction resistance element 22 and the first connecting member 12, so as to cut off the power transmission between the first power element 11 and the first connecting member 12. In the second state, the worm 21 is released from the locking to the driving gear 131, so as to make the first power element 11 drive the first connecting member 12 to rotate.

[0046] In this embodiment, one end of the friction resistance member 22 is coaxially connected to the first driven wheel 132, and the other end of the friction resistance member 22 is connected to the first connecting member 12.

[0047] In this embodiment, the first driven wheel 132 is provided with a torque plate 15, and the clamping torque of the torque plate 15 is greater than the maximum rotational inertia torque of the display part 6. In the case of manual rotation, that is, in the first state of the clutch structure 2, the display structure rotates under the force of the operator, and the friction resistance member 22 rotates alone relative to the first driven wheel 132. At this time, the clamping force of the torque plate 15 is greater than the force of the friction resistance member 22 when it rotates. Therefore, the friction resistance member 22 cannot drive the first driven wheel 132 to rotate. In this way, the damage to the worm gear 21 or the internal structure of the first gear set 13 caused by the first gear set 13 rotating under the action of the friction resistance member 22 can be reduced.

[0048] In this embodiment of the application, when the first power member 11 drives the first gear set 13 to rotate, that is, in the second state of the clutch structure 2, since the frictional force between the structure of the first driven wheel 132 and the torque plate 15 and the frictional resistance member 22 is greater than the holding force of the frictional resistance member 22 itself, the frictional resistance member 22 will rotate under the drive of the first driven wheel 132.

[0049] In the electronic device of this application embodiment, due to the locking of the worm gear 21 and the drive wheel 131, and the locking force of the worm gear 21 and the drive wheel 131 being set to be greater than the frictional force between the frictional resistance member 22 and the first connecting member 12, the irreversible characteristic of the worm gear 21 transmission can be utilized in the first state, i.e., the drive wheel 131 cannot drive the worm gear 21, completely locking the output end of the first power member 11. At this time, when the user manually rotates the display part 6, the driving torque can only overcome the small frictional force provided by the frictional resistance member 22 and make it rotate, but cannot drive the worm gear 21 and the motor in the reverse direction, thereby cutting off the power transmission path and realizing efficient, labor-saving and stable manual rotation of the display part 6. At the same time, it reduces the reverse impact or damage to the motor. The frictional resistance member 22 can eliminate motion jitter during rotation and improve the operating feel. In the second state, the worm gear 21 and the drive wheel 131 are unlocked, and the motor can smoothly transmit torque through the worm gear 21, gear set and frictional resistance member 22 to drive the display part 6 to rotate.

[0050] In some possible embodiments of this application, reference is made to Figure 3 , Figure 4 and Figure 5 The first gear set 13 also includes a second driven wheel 133, which is connected to the first connecting member 12 in a transmission manner. The electronic device also includes a first detection member 3, which is disposed on the second driven wheel 133 to detect the rotation angle of the power end of the first power member 11.

[0051] In this embodiment, the second driven wheel 133 can mesh with the first driven wheel 132, and the second driven wheel 133 can also mesh with other gears in the first gear set 13. When the display part 6 rotates relative to the main body part, all the gears in the first gear set rotate relative to each other, so that the rotation between the second driven wheel 133 and the display part 6 is synchronous and in a fixed proportion.

[0052] In this embodiment, the first detection element 3 is an angle sensor, such as an encoder or potentiometer. The first detection element 3 is mounted on the second driven wheel 133 and is used to detect the rotation angle of the second driven wheel 133. Since the second driven wheel 133 and the first connecting member 12 are connected by a transmission, there is a fixed transmission ratio between the rotation of the second driven wheel 133 and the first connecting member 12. Therefore, by detecting the rotation angle of the second driven wheel 133 and calculating based on the transmission ratio, the rotation angle of the power end of the first power member 11 can be indirectly calculated, and thus the rotation angle of the display part 6 can be determined.

[0053] For example, the first detection element 3 can be a magnetic encoder. One of the magnets or the encoder chip is mounted on the shaft of the second driven wheel 133, and the other is disposed on another structure near the first detection element 3. When the second driven wheel 133 rotates, the encoder chip calculates the angle by detecting the change in the magnetic field.

[0054] In the electronic device of this application embodiment, since the second driven wheel 133 is connected to the first connecting member 12 and the first detection member 3 is disposed on the second driven wheel 133, the actual rotation angle of the power end of the first power member 11 can be indirectly calculated by detecting the rotation angle of the second driven wheel 133, and then the real-time rotation position of the display part 6 can be inferred. The first detection member 3 is disposed on the second driven wheel 133, which is equivalent to a gap between the first detection member 3 and the first power member 11. The angle change is amplified by the gear transmission ratio in the first gear set 13, which improves the resolution of angle detection and the accuracy of system control, and provides feedback signals and data support for the electronic device to realize intelligent hovering, precise positioning and automatic adjustment.

[0055] In some possible embodiments of this application, reference is made to Figure 3 , Figure 4 and Figure 5 The first rotating structure 1 includes a first base 14, which is fixed to the main unit 7. The first connector 12 is rotatably disposed on the first base 14. The electronic device also includes a first damping structure 4, which is disposed between the first connector 12 and the first base 14 to increase the friction between the first connector 12 and the first base 14.

[0056] In this embodiment, the first base 14 serves as the mounting foundation and load-bearing frame for the first rotating structure 1. The first base 14 is disposed on the main unit 7, and the first power component 11, the first gear set 13, and the first connecting component 12 are all directly or indirectly mounted on the first base 14. The first base 14 can be a two-part housing 53, with the two housing parts enclosing a receiving space. The first power component 11 and the first gear set 13 are both disposed within the receiving space, and the first connecting component 12 is disposed on the surface of one of the housing parts 53. The two housing parts 53 are connected by screws.

[0057] In this embodiment of the application, the first damping structure 4 includes a butterfly-shaped spring 41, which is disposed between the friction resistance member 22 and the first base 14. The butterfly-shaped spring 41 is used to provide a stable elastic force between the friction resistance member 22 and the first base 14, and can limit the position between the friction resistance member 22 and the first base 14.

[0058] In this embodiment of the application, the first damping structure 4 further includes a bearing 42, which is sleeved on the outer periphery of the friction resistance member 22 and located between the friction resistance member 22 and the first base 14, thereby enabling the friction resistance member 22 to rotate relative to the first base 14.

[0059] In this embodiment of the application, the first damping structure 4 further includes a fixed friction plate 43, which is disposed between the first connector 12 and the first base 14. The fixed friction plate can also be disposed between the friction resistance member 22 and the first base 14, providing fixed friction resistance during the rotation of the first connector 12 relative to the first base 14 or during the rotation of the friction resistance member 22 relative to the first base 14.

[0060] In the electronic device of this application embodiment, since the first damping structure 4 is disposed between the first connector 12 and the first base 14, and the first base 14 is fixed to the host part 7, the first damping structure 4 can provide frictional resistance, thereby increasing the smoothness and stability of the rotation of the first connector 12 relative to the first base 14. The damping force provided by the first damping structure 4 can not only counteract the "smiling" problem caused by the change of screen gravitational torque, so that the screen can be stably suspended at any angle, but also absorb the vibration and noise generated by the motor transmission when the first power component 11 is driven, and improve the operating feel during manual operation.

[0061] In some possible embodiments of this application, reference is made to Figure 1 , Figure 6 and Figure 7 The electronic device also includes a second rotating structure 5, which includes a second power member 51 and a second connecting member 52. The power end of the second power member 51 is connected to the second connecting member 52 for driving the second connecting member 52 to rotate. One of the second power member 51 and the second connecting member 52 is fixedly connected to the first connecting member 12, and the other of the second power member 51 and the second connecting member 52 is fixedly connected to the display part 6 for connecting the first connecting member 12 to the display part 6. The rotation axis of the power end of the first power member 11 is at an angle to the rotation axis of the power end of the second power member 51.

[0062] In this embodiment, the second rotating structure 5 is used to drive the display part 6 to rotate around the axis of the second rotating structure. The axis of the second rotating structure 5 is the same as the axis of the connection area between the display part 6 and the host part 7. That is, the second rotating structure 5 is used to drive the display part 6 to rotate vertically relative to the host part 7. It can also be understood as vertical rotation. That is, through the second rotating structure 5, the display part 6 can be attached to or rotated to an angled state relative to the host part 7.

[0063] In this embodiment, both the first connector 12 and the second connector 52 have internal threaded holes. The first connector 12 and the second connector 52 are connected by screws or bolts, so that the second connector 52 can rotate with the first connector 12.

[0064] In this embodiment, the display portion 6 can be rotated in two dimensions through the cooperation of the first rotating structure 1 and the second rotating structure 5. For example, the second rotating structure 5 can be used to rotate the mutually fitted display portion 6 and the main body portion open to 90 degrees, and then the second rotating mechanism can be used to rotate the display portion 6 around an axis perpendicular to the main body portion, so that the display portion 6 has an angle with the main body portion in both spatial directions. In this embodiment, the angle of rotation of the display portion 6 relative to the main body portion can be any angle between 0 degrees and 360 degrees, and this application does not limit this angle.

[0065] In the electronic device of this application embodiment, since the power end of the second power member 51 is connected to the second connector 52 through a transmission connection, the driving force of the second power member 51 can drive the second connector 52 to rotate. One of the second power member 51 and the second connector 52 is fixedly connected to the first connector 12, that is, the first connector 12 can rotate under the drive of the second power member 51, and the first connector 12 can also rotate under the drive of the second connector 52. The other of the second power member 51 and the second connector 52 is fixedly connected to the display part 6. Thus, the first rotation structure 1 and the display part 6 can be connected through the second rotation structure 5. Without affecting the function of the first rotation structure 1, the second power member 51 can independently drive the display part 6 to rotate relative to the host part 7. This allows the electronic device to realize a composite rotation function of the display part 6 with multiple degrees of freedom and without mutual interference through the rotation of the display part 6 relative to the host part 7 by the first rotation structure 1 and the second rotation structure 5, thereby expanding the usage mode of the electronic device.

[0066] In some possible embodiments of this application, reference is made to Figure 6 , Figure 7 and Figure 8 The second rotating structure 5 also includes a housing 53 and a second detection element 54. The second power element 51 and the second detection element 54 are both disposed in the housing 53, and the second detection element 54 is electrically connected to the second power element 51 to detect the rotation angle of the power end on the second power element 51.

[0067] In this embodiment, the housing 53 provides external protection for the second rotating structure 5 and serves as the mounting base for its internal structure. For example, both the second power component 51 and the second detection component 54 are housed within the housing 53. The power output shaft 511 extends out of the housing 53 and connects to the second connecting component 52. In this embodiment, the second detection component 54 is an angle sensor, which can be a magnetic encoder, an optical encoder, or a positioner.

[0068] In the electronic device of this application embodiment, since both the second detection element 54 and the second power element 51 are disposed within the housing 53 and are electrically connected, the second detection element 54 can detect the rotation angle of the output shaft of the second power element 51 in real time, and thus can calculate the rotation angle of the display part 6 relative to the host part 7. At the same time, since both the second power element 51 and the second detection element 54 are disposed within the housing 53, it not only saves space and simplifies the overall structural layout, but also reduces external interference to the second detection element 54, thereby improving the reliability and accuracy of angle detection.

[0069] In some possible embodiments of this application, reference is made to Figure 6 , Figure 7 and Figure 8 The second rotating structure 5 also includes a signal transmission line 55, one end of which is electrically connected to the second detection element 54, and the other end of which is electrically connected to the host unit 7. The signal transmission line 55 is provided via the second connector 52 to transmit the detection information of the second detection element 54 to the host unit 7.

[0070] In this embodiment, the signal transmission line 55 is a flexible cable (such as a flat panel cable, FPC). The signal transmission line 55 is responsible for transmitting the angle data signal generated by the second detection element 54 and / or the power required by the second power element 51. In this embodiment, the fact that one end of the signal transmission line 55 is electrically connected to the second detection element 54 and the other end is electrically connected to the host part 7 means that the starting point of the signal transmission line 55 is inside the housing 53, directly connected to the sensor, and the other end of the signal transmission line 55 sends the signal to the host motherboard.

[0071] In this embodiment, a snap-fit ​​structure 531, a wire groove, or a fixing post is provided inside the housing 53, at the outlet, or outside the housing 53. For example, a snap-fit ​​structure 531 is provided on the outer surface of the housing 53, and the signal transmission line 55 can be snapped in the snap-fit ​​mechanism to limit the signal transmission line 55, reduce the loosening of the signal transmission line 55 inside or outside the housing 53, and reduce the interference between the signal transmission line 55 and moving parts such as gears, which could lead to wear or displacement.

[0072] In this embodiment, the second connector 52 has a through hole 521, through which a transmission line can be arranged from inside the housing 53 via the snap-fit ​​structure 531 and the second connector 52, and connected to the main body from the through hole 521 of the second connector 52. In one embodiment, both ends of the second connector 52 are provided with a housing 53, a second power member 51, and a second detection member 54, and both are provided with signal transmission lines 55. The signal transmission lines 55 at both ends of the second connector 52 converge at the through hole 521 and pass through the through hole 521 to connect to the main body.

[0073] In the electronic device of this application embodiment, since one end of the signal transmission line 55 is electrically connected to the second detection element 54, and the other end of the signal transmission line 55 is electrically connected to the host part 7 after being arranged through the second connector 52, a stable and reliable signal path can be established between the second detection element 54 and the host main control unit. At the same time, the signal transmission line 55 is set through the second connector 52, which serves as the fixing and routing path of the signal transmission line 55. This can reduce the wear or breakage of the signal line caused by arbitrary bending during rotation, and effectively reduce the noise impact of electromagnetic interference on weak detection signals, thereby improving the stability of angle feedback.

[0074] In some possible embodiments of this application, reference is made to Figure 6 , Figure 7 and Figure 8 The second rotating structure 5 also includes a second gear set 56, and the second connecting member 52 is a connecting shaft. The power end of the second power member 51 is connected to the second connecting member 52 through the second gear set 56, so as to make the rotation axis of the power end of the second power member 51 parallel to the rotation axis of the second connecting member 52.

[0075] In this embodiment, the second gear set 56 may include an output bearing 561, a motor bracket 562, and at least one gear. The motor bracket 562 is used to fix the second power member 51, enabling the gear of the second power member 51 to mesh correctly with other gears; at least one gear is mounted on the driving gear on the motor output shaft; the output bearing 56142 connects to the power output shaft 511, and the output bearing 56142 serves the output shaft of the second power member 51, improving the stable connection between the second power member 51 and the second connecting member 52. The second gear set 56 may also include a damper 563, which can improve the rotational stability of the second rotating structure 5.

[0076] In the electronic device of this application embodiment, since the power end of the second power member 51 is connected to the second connecting member 52, which serves as a connecting shaft, through the second gear set 56, and the rotation axis of the second power member 51 is parallel to the rotation axis of the second connecting member 52, the power direction can be transmitted in the same direction through the gear set, and the torque can also be amplified. This allows the torque output by the second power member 51 to stably drive the display part 6 to rotate, reducing the generation of two forces. At the same time, the parallel axis reduces the overall thickness of the second rotating structure 5.

[0077] In some possible embodiments of this application, reference is made to Figure 6 , Figure 7 and Figure 8 The second rotating structure 5 includes a second base 57, and a second connector 52 is rotatably disposed on the second base 57; the electronic device also includes a second damping structure, which is disposed between the second connector 52 and the second base 57 to increase the friction between the second connector 52 and the second base 57.

[0078] In this embodiment, the second base 57 serves as the mounting base for the second connecting structure. For example, the second base 57 can be fixed to the first connector 12 by screws or other means. The second base 57 is disposed around the periphery of the second connector 52, thus shielding the second connector 52.

[0079] In this embodiment, the second connector 52 can be mounted on the second base 57 by means of a structure such as a bearing 42 or a bushing, so that the second connector 52 can rotate freely relative to the second base 57.

[0080] In this embodiment of the application, the second damping structure provides frictional resistance to the rotation of the second connector 52. For example, a friction disk can be provided on the rotating shaft of the second connector 52, and a friction surface can be provided at a corresponding position on the second base 57. A wave spring provides a clamping force between the friction disk and the friction surface, and the magnitude of the damping force is set by adjusting the preload of the wave spring.

[0081] The electronic device of this application embodiment, since the second damping structure is disposed between the second connector 52 and the second base 57, can provide stable frictional resistance and reduce the unexpected movement of the second connector 52 during rotation; and the damping force of the second damping structure can offset the "smiling" problem caused by the change of gravitational torque of the display part 6, so that the display part 6 can be stably suspended at any angle rotated by the second rotating structure 5, and can absorb vibration and noise when driven by the second power member 51.

[0082] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.

In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
