Detailed Implementation
[0055] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0056] In the embodiments described in this application, it should be noted that, unless otherwise stated and limited, the term "connection" should be interpreted broadly. For example, it can be an electrical connection, or a connection between two internal components. It can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above term according to the specific circumstances.
[0057] It should be noted that the terms "first," "second," and "third" used in the embodiments of this application are merely used to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted. It should be understood that the objects distinguished by "first," "second," and "third" can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein.
[0058] The connection device and electronic device described in the embodiments of this application will be described in detail below with reference to Figures 1 to 13.
[0059] The connecting device includes: a base 100, a first rotating shaft assembly 200, and a drive assembly 300. The first rotating shaft assembly 200 is rotatably connected to the base 100, and a first damping structure 400 is provided between the first rotating shaft assembly 200 and the base 100; the drive assembly 300 is disposed on the base 100, and a second damping structure 500 is provided between the drive assembly 300 and the first rotating shaft assembly 200; the drive assembly 300 is used to drive the first rotating shaft assembly 200 to rotate through the second damping structure 500; the damping force of the second damping structure 500 is less than the static torque of the drive assembly 300; wherein, the driving torque provided by the drive assembly 300 to the first rotating shaft assembly 200 through the second damping structure 500 is greater than the damping torque provided by the first damping structure 400 to the first rotating shaft assembly 200.
[0060] During operation, the drive assembly 300 can drive the first rotating shaft assembly 200 to rotate through the second damping structure 500. Here, the first damping structure 400 can provide damping force for the rotation of the first rotating shaft assembly 200.
[0061] When an external force is applied to the first rotating shaft assembly 200 to cause the first rotating shaft assembly 200 to rotate, the first damping structure 400 provides damping force for the rotation of the first rotating shaft assembly 200, and the second damping structure 500 also provides damping force for the rotation of the first rotating shaft assembly 200. Since the damping force of the second damping structure 500 is less than the static torque of the drive assembly 300, the drive assembly 300 remains stationary.
[0062] In related technologies, the rotating shaft structure of the connection structure is generally rotated manually, resulting in a limited rotation mode and poor adaptability. However, the connection device of this application can automatically drive the first rotating shaft assembly 200 to rotate via the drive component 300, and can also be rotated by external force, thereby greatly improving the adaptability of the connection device.
[0063] In this embodiment, the structure of the base 100 is not limited. For example, the base 100 can be a plate-like structure or a block-like structure.
[0064] As an example, as shown in Figure 2, the base 100 may include a base plate 110, a mounting plate 120, and a cover plate 130. The mounting plate 120 and the cover plate 130 may be fixedly connected by means of bonding, snap-fitting, welding, etc.; alternatively, the mounting plate 120 and the cover plate 130 may be different parts of a single structural component. The base plate 110 and the mounting plate 120 may be fixedly connected by means of bonding, snap-fitting, welding, etc.; alternatively, the base plate 110 and the mounting plate 120 may both be fixed to other structures. Of course, the base plate 110, the mounting plate 120, and the cover plate 130 may also be different parts of a single structural component. An installation space may be defined between the base plate 110 and the mounting plate 120, and at least a portion of the first damping structure 400, the second damping structure 500, and the drive assembly 300 may be disposed within this installation space. The first rotating shaft assembly 200 may be rotatably connected to both the mounting plate 120 and the base plate 110, and a portion of the first rotating shaft assembly 200 may be located within the installation space.
[0065] In one application, as shown in Figures 2 and 3, the base plate 110 has a first mounting hole 111; the mounting plate 120 has a second mounting hole 125; the connecting device may further include: a first bearing 920, the inner ring of the first bearing 920 being sleeved on the outside of the first rotating shaft assembly 200, and the outer ring of the first bearing 920 being installed in the second mounting hole 125; the first end of the first rotating shaft assembly 200 is rotatably disposed at the first mounting hole 111 through the mounting space; the second end of the first rotating shaft assembly 200 is located outside the mounting plate 120, and the first rotating shaft assembly 200 can be rotated by applying an external force to the first rotating shaft assembly 200 through the second end of the first rotating shaft assembly 200.
[0066] In this embodiment, the structure of the first rotating shaft assembly 200 is not limited. For example, the first rotating shaft assembly 200 may include only one shaft. As another example, as shown in Figures 2 and 3, the first rotating shaft assembly 200 may include a first rotating shaft member 210 and an adjusting member 220; the adjusting member 220 can be rotatably connected to a first end of the first rotating shaft member 210 via a threaded structure to adjust the axial distance between the adjusting member 220 and the second end of the first rotating shaft member 210. Here, the first rotating shaft member 210 may be a hollow shaft, and the adjusting member 220 may also be a cylindrical structure, so that a connecting line is provided in the cavity in the middle of the first rotating shaft member 210 and the adjusting member 220. Of course, in other examples, the first rotating shaft assembly 200 may also include only the first rotating shaft member 210.
[0067] The method by which the first rotating shaft assembly 200 is rotatably connected to the base 100 is not limited. For example, the first rotating shaft assembly 200 can be rotatably connected to the base 100 through a mounting hole. As an example, the first rotating shaft assembly 200 includes a first rotating shaft member 210 and an adjusting member 220. The base plate 110 has a first mounting hole 111; the mounting plate 120 has a second mounting hole 125; the adjusting member 220 is rotatably disposed in the first mounting hole 111; the inner ring of the first bearing 920 is sleeved on the outer side of the first rotating shaft member 210; and the outer ring of the first bearing 920 is installed in the second mounting hole 125.
[0068] In the embodiments of this application, the form of the first damping structure 400 is not limited. For example, the first damping structure 400 can be a structure formed directly between the surface of the first pivot assembly 200 and the surface of the seat 100. As another example, the first damping structure 400 can also be a structure formed between the first pivot assembly 200 and the seat 100 and the first pivot assembly 200 or the seat 100.
[0069] In this embodiment, the structure of the drive assembly 300 is not limited. For example, the drive assembly 300 may include a drive member 310 and a gear assembly, wherein the drive member 310 is capable of driving the gear assembly to rotate, and the rotation of the gear assembly drives the first rotating shaft assembly 200 to rotate via the second damping structure 500. Here, the structure of the drive member 310 is not limited. For example, the drive member 310 may include a motor. The structure of the gear assembly is not limited; for example, the gear assembly may include at least one gear. As another example, the gear assembly may include a worm gear 330 and a worm 340.
[0070] In the embodiments of this application, the form of the second damping structure 500 is not limited. For example, the second damping structure 500 can be a structure formed directly between the surface of the first rotating shaft assembly 200 and the surface of the drive assembly 300. As another example, the second damping structure 500 can also be a structure formed between the first rotating shaft assembly 200 and the drive assembly 300 and the first rotating shaft assembly 200 or the drive assembly 300.
[0071] Because the damping force of the second damping structure 500 is less than the static torque of the drive assembly 300, when an external force is applied to the first rotating shaft assembly 200, the first rotating shaft assembly 200 rotates while the drive assembly 300 remains stationary, with the second damping structure 500 providing the damping force for rotation. Simultaneously, when the drive assembly 300 operates, because the driving torque provided by the drive assembly 300 to the first rotating shaft assembly 200 through the second damping structure 500 is greater than the damping torque provided by the first damping structure 400, the drive assembly 300 can drive the first rotating shaft assembly 200 to rotate through the second damping structure 500. The second damping structure 500 allows the first rotating shaft assembly 200 to rotate both through external force and through the drive assembly 300, thus greatly improving the adaptability of the connecting device. Furthermore, the first damping structure 400 provides damping force for the rotation of the first rotating shaft assembly 200.
[0072] During the rotation of the first rotating shaft assembly 200, the value of the damping force provided by the first damping structure 400 can be fixed or varied. When the value of the damping force provided by the first damping structure 400 varies, the first damping structure 400 can provide different tactile forces when an external force is applied to the rotation of the first rotating shaft assembly 200. By providing different tactile forces, the first damping structure 400 can provide a prompt to the operator for rotating the first rotating shaft assembly 200.
[0073] In some optional implementations of the embodiments of this application, the connecting device may further include a second rotating shaft assembly 600, which is connected to the first rotating shaft assembly 200; the axis of the second rotating shaft assembly 600 is different from the axis of the first rotating shaft assembly 200, so that the connecting device can rotate about the axis of the first rotating shaft assembly and about the axis of the second rotating shaft assembly 600.
[0074] In this implementation, the axis of the second rotating shaft assembly 600 and the axis of the first rotating shaft assembly 200 can be parallel or intersecting. As an example, as shown in FIG1, the axis of the second rotating shaft assembly 600 is perpendicular to the axis of the first rotating shaft assembly 200, thereby enabling the connecting device to rotate in two perpendicular directions.
[0075] In this implementation, the method of connecting the second rotating shaft assembly 600 to the first rotating shaft assembly 200 is not limited. For example, the second rotating shaft assembly 600 can be directly connected to the first rotating shaft assembly 200 by welding, snap-fitting, bonding, or other methods. As an example, when the first rotating shaft assembly 200 includes a first rotating shaft member 210, the second rotating shaft assembly 600 can be directly connected to the first rotating shaft member 210 by welding, snap-fitting, bonding, or other methods.
[0076] For example, as shown in Figures 1 and 2, the connecting device may further include a first connecting member 940. The first connecting member 940 can be fixed to the first rotating shaft assembly 200 by means of snap-fitting, bonding, welding, etc. The first connecting member 940 and the second rotating shaft assembly 600 can be fixedly connected by means of snap-fitting, bonding, welding, etc. When an external force is applied to the second rotating shaft assembly 600 to generate torque, the second rotating shaft assembly 600 rotates. When an external force is applied to the second rotating shaft assembly 600 to generate torque in the first rotating shaft assembly 200, the second rotating shaft assembly 600 drives the first rotating shaft assembly 200 to rotate.
[0077] In this implementation, as shown in Figures 1 and 3, the second rotating shaft assembly 600 may include a second rotating shaft member 620 and a fixed housing 610; the second rotating shaft member 620 may be rotatably disposed on the fixed housing 610; the fixed housing 610 may be directly connected to the first rotating shaft assembly 200, or may be connected to the first rotating shaft assembly 200 through the first connector 940.
[0078] Here, the connecting device may further include a second connector 950, which can be connected to the second rotating shaft assembly 600 so that the second rotating shaft assembly 600 can be connected to other structures via the second connector 950. As an example, the second connector 950 and the second rotating shaft 620 can be fixedly connected by means of snap-fitting, bonding, welding, etc.; when an external force is applied to the second connector 950, the second connector 950 can drive the second rotating shaft 620 to rotate relative to the fixed housing 610.
[0079] In some optional implementations of the embodiments of this application, the first damping structure 400 may include at least one first mating part 410 and at least one second mating part 420. The at least one first mating part 410 is disposed on the outer side of the first rotating shaft assembly 200; the at least one second mating part 420 is disposed on the seat 100; the second mating part 420 is located on the rotation path of the first mating part 410; when the positions of the first mating part 410 and the second mating part 420 are misaligned, the first damping structure 400 provides a first damping force; when the positions of the first mating part 410 and the second mating part 420 are corresponding, the first damping structure 400 provides a second damping force; the first damping force and the second damping force are different, so that the value of the damping force provided by the first damping structure 400 can be varied through the first mating part 410 and the second mating part 420.
[0080] Of course, in other implementations, the first damping structure 400 may not include the first mating part 410 and the second mating part 420. The first damping structure 400 may be formed by the overall outer surface of the first rotating shaft assembly 200 in the circumferential direction mating with the surface of the seat 100. As an example, the seat 100 may have an annular groove on the outer side of the first rotating shaft assembly 200, and the outer surface of the first rotating shaft assembly 200 may contact the bottom and / or side surfaces of the annular groove to have a damping force.
[0081] In this implementation, the first mating part 410 can be directly disposed on the outside of the first rotating shaft assembly 200, where the first rotating shaft assembly 200 includes the first mating part 410. Of course, the first mating part 410 can also be disposed on other structures on the outside of the first rotating shaft assembly 200, where the first rotating shaft assembly 200 does not include the first mating part 410.
[0082] In this implementation, the second mating part 420 can be directly disposed on the base 100, where the base 100 includes the second mating part 420. Of course, the second mating part 420 can also be disposed on other structures at the base 100, where the base 100 does not include the second mating part 420.
[0083] In this implementation, the structure of the first mating part 410 and the second mating part 420 is not limited.
[0084] For example, one of the first mating part 410 and the second mating part 420 can be a protruding structure, and the other of the first mating part 410 and the second mating part 420 can be a groove structure. When the protruding structure is located inside the groove structure, the second damping force between the protruding structure and the groove structure can be small, or the second damping force can be zero. When the protruding structure is located outside the groove structure, the first damping force between the area outside the protruding structure and the groove structure can be large, and the first damping force can be greater than the second damping force.
[0085] Here, the location of the protruding structure is not limited. For example, the protruding structure can be radially protruding; the groove structure can be located in the radial direction of the protruding structure. As another example, the protruding structure can be axially protruding, and the groove structure can be located in the axial direction of the protruding structure.
[0086] In this implementation, the number of first mating parts 410 and second mating parts 420 is not limited. For example, the number of first mating parts 410 and second mating parts 420 can both be two. The two first mating parts 410 can be arranged opposite each other, and the two second mating parts 420 can be arranged opposite each other.
[0087] Example 1, as shown in Figures 7, 8 and 9, the first mating part 410 can be a protruding structure, and the second mating part 420 can be a groove structure.
[0088] In Example 1, the base 100 has a first guide ramp 121 and a second guide ramp 122 on opposite sides of the groove structure along the rotation direction of the first rotating shaft assembly 200, so that the protruding structure slides into the groove structure via the first guide ramp 121 or the second guide ramp 122; thereby, through the guiding effect of the first guide ramp 121 and the second guide ramp 122, a varying tactile force can be provided for the rotation of the first rotating shaft assembly 200. Here, when an external force is applied to the rotation of the first rotating shaft assembly 200, and the protruding structure passes through the first guide ramp 121 or the second guide ramp 122, no further external force needs to be applied, and the first rotating shaft assembly 200 can automatically enter the groove structure through the guiding effect of the first guide ramp 121 or the second guide ramp 122, thereby providing the operator with a varying tactile force.
[0089] Here, the angle between the first guide slope 121 and the second guide slope 122 in the rotation direction can be greater than the deviation angle of the drive assembly 300 driving the first rotating shaft assembly 200 to rotate relative to the seat 100.
[0090] The deviation angle is the difference between the actual angle at which the drive assembly 300 drives the first rotating shaft assembly 200 to rotate and the target angle. The target angle is the angle at which the controller controls the drive assembly 300 to drive the first rotating shaft assembly 200 to rotate. Because the angles of the first guide slope 121 and the second guide slope 122 in the rotation direction are greater than the deviation angle during the rotation of the drive assembly 300 relative to the seat 100, the guiding effect of the first guide slope 121 and the second guide slope 122 allows the angle at which the first rotating shaft assembly 200 automatically rotates to compensate for the deviation angle. This ensures that the angle at which the drive assembly 300 drives the first rotating shaft assembly 200 to rotate reaches the target angle via either the first guide slope 121 or the second guide slope 122, thus improving the accuracy of the angle at which the drive assembly 300 drives the first rotating shaft assembly 200 to rotate.
[0091] In Example 1, the seat 100 may also have a first protrusion 123 and a second protrusion 124 on opposite sides of the groove structure along the rotation direction of the first rotating shaft assembly 200. The first protrusion 123 is adjacent to the first guide slope 121 and is located on the side of the first guide slope 121 away from the groove structure; the second protrusion 124 is adjacent to the second guide slope 122 and is located on the side of the second guide slope 122 away from the groove structure. During the rotation of the raised structure driven by the first rotating shaft assembly 200, the raised structure enters the groove structure via the first protrusion 123 and the first guide slope 121; or, the raised structure enters the groove structure via the second protrusion 124 and the second guide slope 122. When the raised structure enters the groove structure, the damping force of the first damping structure 400 increases when it passes the first protrusion 123 or the second protrusion 124; when the raised structure passes the first guide slope 121 or the second guide slope 122, the damping force of the first damping structure 400 decreases. The first damping force of the first damping structure 400 first increases and then decreases, which can provide a more obvious change in tactile force, thereby providing a more obvious indication for the operator.
[0092] Here, the seat 100 may have a groove 126, and a portion of the first rotating shaft assembly 200 may be located within the groove 126. The groove structure, the first guide slope 121, the second guide slope 122, the first protrusion 123, and the second protrusion 124 may be located on the sidewall of the groove 126, as shown in Figures 7, 8, and 9. The protrusion structure may be located on the outer periphery of the first rotating shaft assembly 200. The groove structure, the first guide slope 121, the second guide slope 122, the first protrusion 123, and the second protrusion 124 may also be located on the bottom wall of the groove 126, and the protrusion structure may be located on the end side of a portion of the first rotating shaft assembly 200.
[0093] In one application, when the first mating part 410 and the second mating part 420 are in corresponding positions, the protruding structure and the groove structure are in corresponding positions, with the protruding structure located within the groove structure. The first rotating shaft assembly 200 can rotate relative to the seat 100 to a first torsional position. In the first torsional position, the damping force of the first damping structure 400 can be minimized. When it is necessary to rotate the first rotating shaft assembly 200 relative to the seat 100 away from the first torsional position, the damping force of the first damping structure 400 increases, requiring a larger external force to be applied to the first rotating shaft assembly 200 so that the protruding structure passes through the first guide ramp 121 and the second guide ramp 122, as well as the first protrusion 123 or the second protrusion 124. When the protruding structure passes over the first protrusion 123 or the second protrusion 124, the damping force of the first damping structure 400 decreases. Here, the protruding structure can contact the side wall or bottom wall of the slide groove 126. By setting a first torsional position corresponding to the value of the damping force of the first damping structure 400, the operator can determine that the first shaft assembly 200 rotates to the first torsional position, thereby greatly improving the adaptability of the connecting device.
[0094] In some optional implementations of the embodiments of this application, as shown in Figures 2 and 3, the first rotating shaft assembly 200 may include: a first rotating shaft member 210, which is rotatably connected to the base 100; the first damping structure 400 may include: a first damping sheet 430. The first damping plate 430 is fixed to the first region of the first rotating shaft 210, and the first damping plate 430 is located on the outer periphery of the first rotating shaft 210; there is a damping force between the first damping plate 430 and the seat 100; the second damping structure 500 may include: a second damping plate 510, the second damping plate 510 is fixed to the second region of the first rotating shaft 210, and the second damping plate 510 is located on the outer periphery of the first rotating shaft 210; there is a damping force between the second damping plate 510 and the drive assembly 300; by separating the first damping plate 430 and the second damping plate 510 from the first rotating shaft 210, it is convenient to process and manufacture the first rotating shaft 210, the first damping plate 430 and the second damping plate 510.
[0095] Of course, in other implementations, the connecting device may include only one of the first damping plate 430 and the second damping plate 510. Alternatively, the connecting device may not include the first damping plate 430 and the second damping plate 510.
[0096] In this implementation, the first rotating shaft 210 is rotatably connected to the base 100 in a manner similar to the above-described implementation of the first rotating shaft assembly 200 being rotatably connected to the base 100, and will not be repeated here.
[0097] In this implementation, the first damping plate 430 can be fixed to the first rotating shaft 210 by means of bonding, snap-fitting, welding, etc.
[0098] The shape of the first damping plate 430 is not limited. For example, as shown in Figures 2 and 3, the first damping plate 430 can be a ring-shaped structure. The first damping plate 430 can be engaged in the first region of the first rotating shaft 210 through a non-circular inner hole so that the first damping plate 430 can rotate together with the first rotating shaft 210.
[0099] The manner in which the damping force is achieved between the first damping plate 430 and the seat 100 is not limited. For example, the outer periphery of the first damping plate 430 contacts the seat 100 and thus has a damping force. Or, for another example, the first damping plate 430 contacts the seat 100 at its end and thus has a damping force.
[0100] During the rotation of the first rotating shaft 210, the damping force between the first damping plate 430 and the seat 100 can be fixed or varied. This variation can be achieved by providing a convex-concave structure on the first damping plate 430 or the seat 100. As an example, there is a damping force between the outer periphery of the first damping plate 430 and the inner wall of the seat 100. Here, a through hole 431 can also be provided near the outer periphery of the first damping plate 430 to give the first damping plate 430 elasticity.
[0101] As another example, the first damping plate 430 may have at least one first mating portion 410, and the seat 100 may have at least one second mating portion 420. When the first mating portion 410 and the second mating portion 420 are misaligned, the first damping structure 400 provides a first damping force; when the first mating portion 410 and the second mating portion 420 are aligned, the first damping structure 400 provides a second damping force; the first damping force and the second damping force are different. In one application, as shown in Figures 7, 8, and 9, two first mating portions 410 are provided on the outer periphery of the first damping plate 430. The two first mating portions 410 are arranged opposite each other, and the seat 100 has two oppositely arranged second mating portions 420; the first mating portions 410 and the second mating portions 420 have been described in the above embodiments and will not be repeated here.
[0102] In this implementation, the second damping plate 510 can be fixed to the first rotating shaft 210 by means of bonding, snap-fitting, welding, etc.
[0103] The shape of the second damping plate 510 is not limited. For example, as shown in Figures 2 and 3, the second damping plate 510 can be a ring-shaped structure. The second damping plate 510 can be engaged in the second region of the first rotating shaft 210 through a non-circular inner hole so that the second damping plate 510 can rotate together with the first rotating shaft 210.
[0104] The manner in which the damping force is achieved between the second damping plate 510 and the drive assembly 300 is not limited. For example, the outer peripheral side of the second damping plate 510 contacts the drive assembly 300 and thus has a damping force. Another example is that the second damping plate 510 contacts the drive assembly 300 at its end and thus has a damping force. As an example, the end side of the second damping plate 510 has a damping force between it and the drive assembly 300.
[0105] During the rotation of the first rotating shaft 210, the value of the damping force between the second damping plate 510 and the drive assembly 300 can remain constant.
[0106] As an example, the drive assembly 300 may include an output member 320 and a drive member 310. The output member 320 is rotatably sleeved outside the first rotating shaft member 210; a second damping plate 510 is pressed between the output member 320 and the first flange 221 on the outer side of the first rotating shaft member 210; the drive member 310 is used to drive the output member 320 to rotate, so as to drive the first rotating shaft member 210 to rotate through the second damping plate 510.
[0107] Because the second damping plate 510 is pressed between the output member 320 and the first flange 221 on the outer side of the first rotating shaft member 210, there is a damping force between the end face of the second damping plate 510 and the output member 320. When the driving member 310 drives the output member 320 to rotate, the output member 320 drives the second damping plate 510 to rotate through the damping force, and the second damping plate 510 drives the first rotating shaft member 210 to rotate.
[0108] By fitting the output component 320 outside the first rotating shaft component 210, the contact area between the output component 320 and the second damping plate 510 can be increased, and the installation space of the output component 320 can be reduced.
[0109] The first pivot member 210 may include a first flange 221. Of course, the first pivot member 210 may also not include the first flange 221. As shown in Figures 2 and 3, the first pivot assembly 200 may also include an adjusting member 220, and the first flange 221 may be disposed on the adjusting member 220.
[0110] The method by which the driving member 310 drives the output member 320 to rotate is not limited. For example, the output member 320 may include a gear one, and a gear two may be fixed on the output shaft of the driving member 310, with gear two meshing with gear one, and the axis of the output shaft of the driving member 310 being parallel to the axis of the first rotating shaft member 210.
[0111] For example, as shown in Figures 2 and 3, the drive assembly 300 may further include a turbine 330 and a worm gear 340. The turbine 330 is rotatably sleeved outside the first rotating shaft 210 and connected to the output member 320; the worm gear 340 is connected to the output shaft of the drive member 310, as shown in Figures 5 and 6; the worm gear 340 and the turbine 330 mesh. Here, the axis of the output shaft is not parallel to the axis of the first rotating shaft 210; the axis of the output shaft and the axis of the first rotating shaft 210 may be perpendicular. The turbine 330 and the output member 320 can be connected by means of bonding, snap-fitting, threaded structure, etc. By separating the output member 320 and the turbine 330, it is convenient to make the output member 320 and the turbine 330 with different materials. As an example, the material of the turbine 330 may be copper, and the material of the output member 320 may be steel. Of course, in other examples, the turbine 330 and the output member 320 may also be a single structural component. The worm gear 340 and the output shaft of the drive component 310 can be connected by snap-fit, welding or other methods.
[0112] Here, as shown in Figures 5 and 6, the connecting device may further include a fixing frame 960, which can be connected to the driving component 310 by snap-fit or adhesive bonding. The driving component 300 can be fixedly mounted by the fixing frame 960, which can be connected to the base 100 by snap-fit or adhesive bonding.
[0113] Of course, in other examples, the drive assembly 300 may also include an adjustment shim 930, which may be rotatably fitted outside the first rotating shaft 210 and pressed between the second damping plate 510 and the output member 320, so that if the output member 320 is not axially sized enough to contact the second damping plate 510, the adjustment shim 930 can contact the second damping plate 510.
[0114] In some optional implementations of the embodiments of this application, the connecting device may further include: an encoder 910, which is used to detect the angle by which the drive component 300 drives the first rotating shaft component 200 to rotate, so that the drive component 300 drives the first rotating shaft component 200 to rotate by a target angle.
[0115] In this implementation, the structure of encoder 910 is not limited. As long as encoder 910 can detect the angle at which drive assembly 300 drives first rotating shaft assembly 200 to rotate, it is acceptable.
[0116] For example, encoder 910 may include a first gear 911, a second gear 912, and a detection component 916. The first gear 911 may be fixed outside the first rotating shaft assembly 200. The second gear 912 meshes with the first gear 911. During the process of the first rotating shaft assembly 200 driving the first gear 911 to rotate, the first gear 911 drives the second gear 912 to rotate. The detection component 916 is used to detect the rotation angle of the first rotating shaft assembly 200 by detecting the rotation angle of the second gear 912.
[0117] Here, the second gear 912 can be fixed to the mounting base 913 by means of snap-fit, threaded structure, welding, etc., and the mounting base 913 can be rotatably mounted on the base body 100 by means of the second bearing 914. For example, the outer ring of the second bearing 914 is fixed to the mounting plate 120, and the inner ring of the second bearing 914 can be sleeved on the protrusion of the mounting base 913, so that the second gear 912 and the mounting base 913 can be rotatably mounted by means of the second bearing 914.
[0118] Here, the encoder 910 may also include a magnet 915, which may be disposed on the second gear 912 or the mounting base 913. The detection component 916 may detect the rotation angle of the second gear 912 through the magnet 915, and thus detect the rotation angle of the first rotating shaft assembly 200.
[0119] Here, the detection component 916 can be fixed to the base 100 by means of snap-fit, adhesive, or other methods. As an example, as shown in Figures 3 and 4, the detection component 916 is fixed to the base plate 110 of the base 100.
[0120] This application also describes an electronic device, including: a first body 700, a base 100, a first rotating shaft assembly 200, a drive assembly 300, and a second body 800. A seat 100 is disposed on a first body 700; a first rotating shaft assembly 200 is rotatably connected to the seat 100, and a first damping structure 400 is provided between the first rotating shaft assembly 200 and the seat 100; a drive assembly 300 is disposed on the seat 100, and a second damping structure 500 is provided between the drive assembly 300 and the first rotating shaft assembly 200; the drive assembly 300 is used to drive the first rotating shaft assembly 200 to rotate through the second damping structure 500; the damping force of the second damping structure 500 is less than the static torque of the drive assembly 300; wherein, the driving torque provided by the drive assembly 300 to the first rotating shaft assembly 200 through the second damping structure 500 is greater than the damping torque provided by the first damping structure 400 to the first rotating shaft assembly 200; a second body 800 is connected to the first rotating shaft assembly 200; the second body 800 is used to rotate relative to the first body 700 through the first rotating shaft assembly 200.
[0121] In this embodiment, the base 100 can be attached to the first body 700 by means of snap-fit, adhesive, threaded structure, etc.
[0122] In this embodiment, the second body 800 can be directly connected to the first rotating shaft assembly 200 by means of bonding, snap-fitting, welding, etc. The second body 800 and the first rotating shaft assembly 200 can also be connected by other structural components. For example, the second body 800 can be connected to the first rotating shaft assembly 200 via a first connector 940.
[0123] The above embodiments have already described the base 100, the first rotating shaft assembly 200, and the drive assembly 300, and will not be repeated here.
[0124] As an example, the electronic device may also include: a second pivot assembly 600 connected to a first pivot assembly 200; and a second body 800 rotatably connected to the second pivot assembly 600 so that the second body 800 can rotate both via the first pivot assembly 200 and via the second pivot assembly 600.
[0125] The second rotating shaft assembly 600 has been described in the above embodiments and will not be repeated here.
[0126] Here, the second body 800 can be directly connected to the second shaft part 620 of the second shaft assembly 600 by means of bonding, welding, snap-fitting, etc., or it can be connected to the second connector 950 by means of bonding, welding, snap-fitting, etc.
[0127] In this embodiment, the orientation of the first rotating shaft assembly 200 is not limited. For example, the first rotating shaft assembly 200 is disposed along the thickness direction of the first body 700; here, the second body 800 is used to rotate relative to the first body 700 via the first rotating shaft assembly 200, and the second body 800 can switch between the state shown in FIG10 and the state shown in FIG11 via the first rotating shaft assembly 200.
[0128] Here, the first pivot member 210 can be arranged along the thickness direction of the first body 700.
[0129] In this embodiment, the orientation of the axis of the second pivot assembly 600 is not limited. For example, the axis of the second pivot assembly 600 and the axis of the first pivot assembly 200 can be perpendicular; the first pivot member 210 can be arranged along the thickness direction of the first body 700; here, the second body 800 is used to rotate relative to the first body 700 via the first pivot assembly 200, and the second body 800 is also used to open and close via the rotation of the second pivot assembly 600 relative to the first body 700; the second body 800 can be engaged with the first body 700 from the state shown in FIG. 10 via the rotation of the second pivot assembly 600 relative to the first body 700, so as to facilitate the carrying of the electronic device. The second body 800 can be rotated from the state shown in FIG. 12 to the state shown in FIG. 13 via the second pivot assembly 600 relative to the first body 700, so as to adjust the pitch angle of the second body 800.
[0130] In this embodiment, during the rotation of the first rotating shaft assembly 200, the value of the damping force provided by the first damping structure 400 changes; under the action of external force, the damping force of the first damping structure 400 is used to determine the first torsional position of the second body 800 relative to the first body 700 via the first rotating shaft assembly 200; or, when the drive assembly 300 drives the second body 800 to torsion relative to the first body 700 via the first rotating shaft assembly 200, the guiding effect of the first damping structure 400 is used to torsion the second body 800 relative to the first body 700 to the first torsional position; at the first torsional position, the second body 800 is used to achieve a locking state by rotating the second rotating shaft assembly 600 relative to the first body 700.
[0131] Here, the first torsional position can be as shown in Figure 10. In the first torsional position, the second body 800 can achieve a locking state by rotating relative to the first body 700 via the second rotating shaft assembly 600. In the locking state, the second body 800 can be substantially stacked on one side of the first body 700, with virtually no misalignment between the second body 800 and the first body 700. As an example, in the locking state, on a projection plane parallel to the first surface, the projection area of the second body 800 is located within the projection area of the first body. The first surface can be the surface of the first body 700 that contacts the bearing surface, and the bearing surface can be the surface that carries the electronic device. As another example, on a projection plane parallel to the first surface, the projection outline of the second body 800 and the projection outline of the first body are approximately the same distance in all directions.
[0132] Here, the above embodiments have already described the implementation of the change in the value of the damping force provided by the first damping structure 400 and the first torsional position, which will not be repeated here.
[0133] At the first torsional position, the damping force of the first damping structure 400 can be either minimum or maximum.
[0134] Here, the guiding function of the first damping structure 400 is not limited in its implementation. For example, the guiding function of the first damping structure 400 can be the guiding function of the first guide slope 121 or the second guide slope 122.

The input component 710 may be disposed on the first body 700. The display component 810 may be disposed on the second body 800.
