Multifunctional and large-size in-vehicle display terminals that can be connected to mobile phones, computers or the Internet have become the mainstream trend of future development. In order to increase the storage function in the car, a storage box is often provided at the bottom of the existing in-vehicle display terminal. The in-vehicle display terminal is connected to a transmission device, which drives the in-vehicle display terminal to open or close the storage box.

[0003] The existing transmission device includes a manual drive mode and an automatic drive mode. The automatic drive mode is used to drive the vehicle display terminal to rotate when the power is on. When the vehicle is in a power-off mode when maintenance is required or the whole vehicle is being assembled, the manual drive mode is required to drive the vehicle display terminal to rotate. In the manual drive mode, the transmission device uses damping to achieve the slow lifting or lowering of the vehicle display terminal, but the damping will also work in the automatic drive mode. Furthermore, the number of working times of the transmission device in the automatic drive mode is much greater than the number of working times of the transmission device in the manual drive mode. Therefore, if the damping works in both the manual drive mode and the automatic drive mode, the service life of the damping will be greatly reduced, resulting in the phenomenon that the damping is easily damaged.

The damping assembly 10 of the present application is applied to the field of automobile manufacturing. In one embodiment, the damping assembly 10 of the present application is applied to the transmission of the vehicle-mounted display terminal. Further, the damping assembly 10 of the present application is used to realize the rotation of the vehicle-mounted display terminal.

[0026] Attached Figure 11 is a schematic diagram of a structure between the damping assembly 10 and the transmission assembly 20 of the present application in the first driving mode. Figure 2 This is a schematic diagram of a structure between the damping assembly 10 and the transmission assembly 20 in the second driving mode of the present application. Figure 1 And attached Figure 2 As shown, the first direction X of the present application refers to the length direction of the damping assembly 10, that is, the direction from left to right of the damping assembly 10 or the direction from right to left of the damping assembly 10.

In the first driving mode, the damping unit 100 is connected to the first transmission part 712 of the transmission assembly 20, and the transmission assembly 20 is in manual mode. In the manual mode, the damping unit 100 participates in the work to slow down the rotation speed of the transmission assembly 20. In the second driving mode, the damping unit 100 is separated from the first transmission part 712 of the transmission assembly 20, and the transmission assembly 20 is in automatic mode. In the automatic mode, the transmission assembly 20 works alone. Therefore, the damping unit 100 only participates in the work in the first driving mode, and does not participate in the work in the second driving mode, which reduces the working time of the damping unit 100 and further increases the service life of the damping unit 100.

[0028] Please refer to the attached Figure 1 And attached Figure 2 As shown, the damping assembly 10 of the present application includes a damping unit 100, and a first rotation axis 110 is provided in the damping unit 100 along the first direction X. The damping unit 100 can rotate around the first rotation axis 110 driven by the transmission assembly 20. Among them, the damping unit 100 includes a damping shell 120 and a damping core 130, and the damping core 130 is installed in the damping shell 120. The damping core 130 interacts with the damping shell 120 to slow down the rotation speed of the damping core 130. Further, a second transmission part is provided on the damping core 130, and a first transmission part 712 is provided on the transmission assembly 20. The second transmission part on the damping core 130 is transmission-connected with the first transmission part 712 on the transmission assembly 20 to form a first driving mode.

[0029] In one embodiment, the transmission method between the first transmission part 712 and the second transmission part is friction transmission or gear transmission. Further, the first transmission part 712 and the second transmission part are gear transmission, and the relative position between the damping component 10 and the transmission component 20 is fixed before moving, and the transmission component 20 is in a stopped transmission device. Therefore, the relative position between the second transmission part of the damping core 130 and the first transmission part 712 of the transmission component 20 is fixed, and no misalignment occurs.

[0030] Please refer to the attached Figure 1 And attached Figure 2 As shown, the damping assembly 10 of the present application also includes a moving unit 200, which is used to drive the damping unit 100 to move along the first direction X to drive the second transmission part of the damping unit 100 to approach or move away from the first transmission part 712 of the transmission assembly 20. When the damping unit 100 moves, the damping unit 100 and the transmission assembly 20 include a first driving mode and a second driving mode.

[0031] The mobile unit 200 includes a first mobile structure 210 and a second mobile structure 220, the first mobile structure 210 and the second mobile structure 220 are located at two ends of the damping unit 100 along the first direction X, and the first mobile structure 210 is used to drive the damping unit 100 to move toward the first transmission location 712 of the transmission assembly 20, so as to achieve transmission connection between the second transmission location on the damping core 130 and the first transmission location 712 on the transmission assembly 20. The second mobile structure 220 is used to drive the damping unit 100 to move away from the first transmission location 712 of the transmission assembly 20, so as to achieve separation of the second transmission location on the damping core 130 from the first transmission location 712 on the transmission assembly 20.

[0032] The second moving structure 220 automatically drives the damping unit 100 away from the first transmission position 712 of the transmission assembly 20 after the transmission assembly 20 rotates to the right position. The specific operation process will be further described in Embodiment 2. In one embodiment, the second moving structure 220 is an elastic structure.

The specific structure of the first moving structure 210 will be described in the attached Figure 7 Further explanation in.

[0034] Please refer to the attached Figure 1 And attached Figure 2As shown, in order to further realize the unidirectional rotation of the damping unit 100, the damping assembly 10 of the present application is also provided with a limit unit 300. In the prior art, the unidirectional rotation of the damping unit 100 is realized by a built-in unidirectional bearing. However, the damping unit 100 of the present application is bidirectionally rotatable, and the unidirectional rotation of the damping assembly 10 is realized by an external limit unit 300.

[0035] Please refer to the attached Figure 1 And attached Figure 2 As shown, the limiting unit 300 of the present application includes a first limiting structure 310 and a second limiting structure 320. The surface of the damping housing 120 is circumferentially arranged with a plurality of first limiting structures 310 at intervals. The second limiting structure 320 is located on one side of the damping housing 120 along the second direction Y. The first limiting structure 310 and the second limiting structure 320 interact with each other to ensure that the damping housing 120 rotates unidirectionally around the first rotation axis 110. The specific structures of the first limiting structure 310 and the second limiting structure 320 will be described in the attached Figure 3 And attached Figure 4 Further described in .

[0036] Attached Figure 3 Schematic diagram of a structure between the damping unit 100 and the limiting unit 300 of the present application. Figure 4 This is another structural diagram of the damping unit 100 and the limiting unit 300 of the present application. Figure 3 And attached Figure 4 As shown, the rotation direction of the damping core 130 of the present application includes forward rotation A around the first rotation axis 110 and reverse rotation B around the first rotation axis 110, and the rotation directions of the forward rotation A and the reverse rotation B are opposite. When the damping core 130 rotates forward A, the transmission assembly rotates in the reverse direction. At this time, the second limiting structure 320 cannot constrain the first limiting structure 310, and the damping core 130 rotates synchronously with the damping shell. When the damping core 130 rotates reversely B, the transmission assembly rotates forward. At this time, the second limiting structure 320 and the first limiting structure 310 constrain each other. At this time, the damping core 130 rotates in the damping shell 120 and serves to slow down the rotation speed of the transmission assembly 20.

[0037] The first limiting structure is a first limiting protrusion arranged on the surface of the damping housing 120, the bottom of the first limiting protrusion is connected to the surface of the damping housing 120, and both sides of the first limiting protrusion have slopes 314, the slopes 314 are arranged around the circumference of the damping housing 120, and the slopes 314 are tangent to the damping housing 120. The first limiting protrusion is provided with a first limiting groove 311 along the first direction, and the first limiting groove 311 includes two correspondingly arranged first side surfaces 312 and second side surfaces 313, the first side surface 312 to the second side surface 313 is the positive direction, and the second side surface 313 to the first side surface 312 is the reverse direction, the first side surface 312 and the second side surface 313 are arranged around the circumference of the damping housing 120, the inclination angle of the first side surface 312 is greater than the inclination angle of the second side surface 313, and the height of the first side surface 312 in the radial direction is higher than the height of the second side surface 313 in the radial direction.

[0038] The second limiting structure 320 includes a second limiting protrusion 321 and a first elastic member 322. The first end of the first elastic member 322 is connected to the second limiting protrusion 321, and the second end of the first elastic member 322 is against the fixed point. The second limiting protrusion 321 is provided with a protrusion on the side facing the damping shell 120, and the protrusion is adapted to the first limiting groove 311. When the damping core 130 rotates, the protrusion can escape from the first limiting groove 311 when the protrusion acts on the first side surface 312, and the damping core 130 rotates synchronously with the damping shell 120. When the damping core 130 rotates, the protrusion is limited in the first limiting groove 311 when the protrusion acts on the second side surface 313, and the damping core 130 rotates alone in the damping shell.

[0039] In the initial state, the protrusion of the second limiting protrusion 321 is located in the first limiting groove 311 of a first limiting protrusion. When entering the first driving mode, if the transmission assembly 20 rotates in the opposite direction B, the damping core 130 rotates in the positive direction A around the first rotation axis 110, and after the protrusion of the second limiting protrusion 321 abuts against the first limiting surface 422, the protrusion of the second limiting protrusion 321 cannot limit the rotation of the first limiting protrusion, and the second limiting protrusion 321 floats upward and disengages from the first limiting groove 311 in the current first limiting protrusion. At this time, the damping shell and the damping core 130 rotate synchronously until the second limiting protrusion 321 enters the next first limiting groove 311 in the rotation direction and the rotation ends.

[0040] In the initial state, the protrusion of the second limiting protrusion 321 is located in the first limiting groove 311 of a first limiting protrusion. When entering the first driving mode, if the transmission assembly 20 rotates forward A, the damping core 130 rotates reversely B around the first rotation axis 110. After the protrusion of the second limiting protrusion abuts against the second limiting surface 610, the protrusion of the second limiting protrusion 321 limits the rotation of the first limiting protrusion. At this time, the damping shell remains stationary, and the damping core 130 rotates alone in the damping shell.

In one embodiment, the transmission device of the present application is applied to the transmission of the vehicle-mounted display terminal. Further, the transmission device of the present application is used to realize the rotation of the vehicle-mounted display terminal.

[0042] Please refer to the attached Figure 5 As shown, the first direction X of the present application refers to the length direction of the transmission device, that is, the direction from left to right of the transmission device or the direction from right to left of the transmission device.

[0043] Attached Figure 5 This is a schematic diagram of the structure of the transmission device of this application. Figure 5 As shown, the transmission device of the present application includes a transmission component 20. In the present application, the transmission component 20 can realize manual rotation and automatic rotation.

The other components of the present application are connected to the rotating shaft 410 in a rotating connection, a fixed connection, or an axially movable connection.

[0045] Please refer to the attached Figure 5As shown, the transmission assembly 20 of the present application also includes a rotating member 420 and a first driving member 500, and the rotating member 420 is rotatably connected with the rotating shaft 410. Further, the rotating member 420 is sleeved outside the rotating shaft 410, and the rotating member 420 rotates around the rotating shaft 410. The rotating member 420 itself and the rotation do not form power transmission, and the rotating member 420 needs to be used in conjunction with the moving member 600 to form power transmission with the rotating shaft 410. The first driving member 500 is in transmission connection with the rotating member 420. Further, the rotating member 420 forms a rotation under the drive of the first driving member 500. If the rotating member 420 and the moving member 600 cooperate at this time, the automatic transmission state of the transmission assembly 20 is formed, that is, the first driving member 500 can directly drive the rotating shaft 410 to rotate through the cooperation of the rotating member 420 and the moving member 600.

[0046] Please refer to the attached Figure 1 As shown, the transmission assembly 20 of the present application also includes a moving member 600 and a second driving member 710. The moving member 600 is arranged on one side of the rotating member 420. The moving member 600 and the rotating shaft 410 are axially movable and connected, and the rotating shaft 410 and the moving member 600 are synchronously rotated and connected. The second driving member 710 is used to drive the moving member 600 to approach the rotating member 420, and the first moving structure 210 is used to drive the moving member 600 away from the rotating member 420.

[0047] Furthermore, the movable member 600 of the present application is formed with a second limiting groove 620 on the side close to the fixed ring 711 , and the damping unit 100 is provided with a movable ring 140 on the side close to the movable member 600 , and the movable ring 140 is located in the second limiting groove 620 to realize synchronous movement of the movable member 600 and the damping unit 100 .

[0050] Please refer to the attached Figure 5 As shown, the transmission assembly 20 of the present application includes a first limit member, which is used to achieve locking of the relative position or disengagement of the relative position between the rotating member 420 and the movable member 600. The first limit member is used in conjunction with the second driving member 710, the first movable structure 210 and the third driving member 820 to form an automatic transmission state, a manual transmission state, and an extreme position state of the transmission assembly 20.

[0051] Further, the moving member 600 moves away from the rotating member 420 under the drive of the first moving structure 210, and under the drive of the third driving member 820, the first stopper 720 between the rotating member 420 and the moving member 600 is misaligned to form a manual transmission state of the transmission assembly 20. In the manual transmission state, the relative position of the first stopper between the rotating member 420 and the moving member 600 is disengaged, and the rotating shaft 410 realizes autonomous rotation by manually rotating the first connecting member 810. Under the drive of the rotating shaft 410, the relative position of the first stopper between the rotating member 420 and the moving member 600 is correspondingly set, and under the drive of the second driving member 710, the moving member 600 moves close to the rotating member 420 to form an automatic transmission state of the transmission assembly 20, in which the first stopper between the rotating member 420 and the moving member 600 is locked with each other, and the first driving member 500 drives the rotating member 420, the moving member 600, the rotating shaft 410 and the first connecting member 810 to rotate in sequence.

[0052] Please refer to the attached Figure 5 As shown, the second driving member 710 of the present application includes a fixed ring 711, which is sleeved outside the rotating shaft 410, the fixed ring 711 is fixedly connected to the rotating shaft 410, and the fixed ring 711 is spaced apart from the moving member 600. The second driving member 710 also includes a second elastic member 713, which is sleeved outside the rotating shaft 410, the first end of the second elastic member 713 is against the moving member 600, and the second end of the second elastic member 713 is against the fixed ring 711. Thus, the second elastic member 713 always gives the moving member 600 a driving force to move axially toward the rotating member 420, and when the first stopper 720 between the rotating member 420 and the moving member 600 is correspondingly arranged, under the drive of the first elastic member 322, the moving member 600 moves close to the rotating member 420.

[0053] Furthermore, the first transmission part 712 of the transmission assembly 20 is arranged on the fixing ring 711 .

[0054] Please refer to the attached Figure 5 As shown, the transmission assembly 20 of the present application further includes a first connecting member 810 , the rotating shaft 410 is connected to the object to be transmitted via the first connecting member 810 , and the first connecting member 810 and the rotating shaft 410 rotate synchronously.

[0055] Furthermore, the first connecting member 810 is fixedly connected to the rotating shaft 410 , and a fixed connection point between the first connecting member 810 and the rotating shaft 410 is located on the circumferential surface of the rotating shaft 410 or the end surface of the rotating shaft 410 .

[0057] Attached Figure 6 This is a schematic diagram of the structure of the first driving member 500 of the present application. Figure 6 As shown, the driving connection between the first driving member 500 and the rotating member 420 of the present application can be a pulley transmission or a gear meshing transmission. When the first driving member 500 and the rotating member 420 are driven by a pulley, a rotating belt is sleeved between the first driving member 500 and the rotating member 420, and the first driving member 500 drives the rotating member 420 to rotate. When the first driving member 500 and the rotating member 420 are driven by a gear meshing transmission, the first driving member 500 has a driving gear, and the rotating member 420 is a driven gear, and the first driving member 500 drives the rotating member 420 to rotate.

[0058] In one embodiment, the first driving member 500 and the rotating member 420 are gear-engaged. Further, the first driving member 500 includes a driving motor 510 and a power transmission mechanism 520, and the power transmission mechanism 520 is respectively connected to the driving motor 510 and the rotating member 420.

[0059] The power transmission mechanism 520 includes a first transmission worm 521, a transmission worm 522 and a second transmission worm 523. The first transmission worm 521 is arranged at the output end of the driving motor 510. The driving motor 510 directly drives the first transmission worm 521 to rotate. The transmission worm 522 is meshed with the first transmission worm 521 to realize the synchronous rotation between the first transmission worm 521 and the transmission worm 522. The second transmission worm 523 is connected with the transmission worm 522 to realize the synchronous rotation between the second transmission worm 523 and the transmission worm 522. Further, the second transmission worm 523 is connected to the rotating member 420 in a transmission manner, so as to realize the rotation of the rotating member 420 driven by the first driving member 500. The meshing between the second transmission worm 523 and the rotating member 420 can realize the self-locking between the rotating member 420 and the first driving member 500, so as to avoid the moving member 600 driving the rotating member 420 to rotate in the manual transmission state.

[0060] Attached Figure 7 This is a structural diagram of the first drive structure of the application. Please refer to the attached Figure 7As shown, the first movable structure 210 of the present application includes a rotating handle 211 and a rotating body 212. The rotating handle 211 is arranged on one side of the rotating body 212. The rotating handle 211 is fixedly connected to the rotating body 212. A second rotating axis 410 line 214 is arranged on the rotating body 212. When the user turns the rotating handle 211, the rotating body 212 rotates around the second rotating axis 410 line 214, thereby further driving the movable member 600 to move.

[0061] In the present application, the first driving structure may also be a pull rod, which pulls the moving member 600 to move away from the rotating member 420 .

[0062] Attached Figure 8 This is a schematic diagram of the structure of the third driving member 820 of the present application. Figure 8 As shown, the third driving member 820 of the present application includes a fixing sleeve 821 , which is sleeved outside the rotating shaft 410 , and the fixing sleeve 821 is fixedly connected to the rotating shaft 410 .

[0063] In one embodiment, the fixing sleeve 821 is fixedly connected to the rotating shaft 410 by a key connection. The fixing sleeve 821 and the rotating shaft 410 are not limited to the key connection, and other connection methods such as welding can also be used.

[0064] The third driving member 820 also includes a third elastic member 822, which is sleeved outside the fixed sleeve 821. The first end and / or the second end of the third elastic member 822 extends outward and abuts against the limit position to form a rotational force that drives the rotating shaft 410 to rotate circumferentially. The transmission assembly 20 of the present application is compressed in the automatic transmission state, thereby storing force for the circumferential rotation of the rotating shaft 410, and the circumferential rotation of the rotating shaft 410 is to form a misalignment between the relative positions of the third limiting structure 721 and the fifth limiting structure 723. When the transmission assembly 20 of the present application is switched from the automatic transmission state to the manual transmission state, the third elastic member 822 releases the stored force for circumferential rotation, thereby forming a misalignment between the third limiting structure 721 and the fifth limiting structure 723.

[0065] In one embodiment, the third elastic member 822 is a torsion spring.

[0066] In one embodiment, the first end of the third elastic member 822 is fixedly connected to the fixing sleeve 821 , and the second end of the third elastic member 822 extends outward and abuts against the limit position.

[0067] Attached Fig. 9 Schematic diagram of the structure of the moving part 600 of the present application. Fig.10 This is another structural diagram of the moving member 600 of the present application. Fig. 9 And attached Fig.10As shown, the moving member 600 of the present application is provided with a through hole, and the moving member 600 is sleeved on the outside of the rotating shaft 410 through the through hole, and a keyway is provided in the through hole, so as to facilitate key connection with the rotating shaft 410. The first end of the moving member 600 has a second limiting surface 610, and the second end of the moving member 600 has a second limiting groove 620, that is, the moving member 600 is formed with a second limiting groove 620 on the side close to the fixed ring 711, and the second limiting groove 620 is formed by a first limiting ring 630 and a second limiting ring 640 arranged at intervals along the first direction X, the first limiting ring 630 and the second limiting ring 640 are arranged to protrude from the outer surface of the moving member 600, the first limiting ring 630 is arranged away from the fixed ring 711 relative to the second limiting ring 640, and the first moving structure 210 is arranged on the side of the first limiting ring 630 away from the fixed ring 711, and the first moving structure 210 can drive the moving member 600 to move when it contacts the first limiting ring 630.

[0068] In the present application, the transmission assembly 20 is switched from the automatic transmission state to the extreme position state, and the moving member 600 rotates along the third direction, which is clockwise or counterclockwise in the present application. A fourth limiting structure 722, a second limiting surface 610, and a fifth limiting structure 723 are sequentially arranged on one side end surface of the moving member 600 along the third direction.

[0069] Further, the fourth limiting structure 722 is arranged on the second limiting surface 610, and the fourth limiting structure 722 is a part of the first limiting member 720, and the fourth limiting structure 722 is one of a limiting protrusion and a limiting groove. In the present application, the limiting groove is adapted to the limiting protrusion. The fifth limiting structure 723 is also arranged on the second limiting surface 610, and the fifth limiting structure 723 is the same type as the fourth limiting structure 722.

[0070] In one embodiment, the fourth limiting structure 722 and the fifth limiting structure 723 are both limiting grooves. Further, the axial depth of the fourth limiting structure 722 is greater than the axial depth of the fifth limiting structure 723, and the radial width of the fourth limiting structure 722 is greater than the radial width of the fifth limiting structure 723.

[0071] Among them, the fourth limiting structure 722 and the fifth limiting structure 723 are both composed of two limiting side surfaces and a limiting bottom surface, the limiting side surfaces are located on both sides of the fourth limiting structure 722 and the fifth limiting structure 723, and the limiting bottom surface is located at the bottom of the fourth limiting structure 722 and the fifth limiting structure 723. An angle is formed between the two limiting side surfaces and the limiting bottom surface to form a guiding effect on the third limiting structure 721. The angle between the limiting side surface and the limiting bottom surface of the fourth limiting structure 722 is consistent with the angle between the limiting side surface and the limiting bottom surface of the fifth limiting structure 723. In the present application, the angle between the limiting side surface and the limiting bottom surface of the fourth limiting structure 722 is consistent with the angle between the limiting side surface and the limiting bottom surface of the fifth limiting structure 723, which is only an embodiment of the present application, so that the third limiting structure 721 has a good fit with the fourth limiting structure 722 and the fifth limiting structure 723.

[0072] Attached Fig.11 4 is a schematic diagram of the structure of the rotating member 420 of the present application. Fig.12 This is another structural schematic diagram of the rotating member 420 of the present application. Fig.11 And attached Fig.12 As shown, a positioning hole 423 is provided through the rotating member 420 of the present application, and the rotating member 420 is sleeved on the outside of the rotating shaft 410 through the positioning hole 423. The rotating member 420 is connected to rotate around the rotating shaft 410. In the present application, the rotating member 420 cannot directly drive the rotating shaft 410 to rotate. One side end face of the rotating member 420 is the first limiting surface 422, and the third limiting structure 721 is provided on the first limiting surface 422, and the third limiting structure 721 is a part of the first limiting member 720, and the third limiting structure 721 is another type of limiting protrusion and limiting groove. In the present application, the limiting groove is adapted to the limiting protrusion.

[0073] In one embodiment, the third limiting structure 721 is a limiting protrusion. The axial depth of the third limiting structure 721 is not less than the axial depth of the fourth limiting structure 722 , and the radial width of the third limiting structure 721 is not less than the radial width of the fourth limiting structure 722 .

[0074] Among them, the third limiting structure 721 is composed of two side surfaces and a top surface, and there is an angle between the two side surfaces of the third limiting structure 721 and the top surface of the third limiting structure 721. The angle between the two side surfaces of the third limiting structure 721 and the top surface of the third limiting structure 721 is consistent with the angle between the limiting side surfaces and the limiting bottom surface of the fourth limiting structure 722 and the fifth limiting structure 723. In the present application, the angle between the two side surfaces of the third limiting structure 721 and the top surface of the third limiting structure 721 is consistent with the angle between the limiting side surfaces and the limiting bottom surface of the fourth limiting structure 722 and the fifth limiting structure 723, which is only an implementation method of the present application, in order to have a good fit between the third limiting structure 721 and the fourth limiting structure 722 and the fifth limiting structure 723.

[0075] In one embodiment, the rotating member 420 is coaxially disposed with the rotating shaft 410 .

[0076] Attached Figure 2 This is a schematic diagram of a structure between the damping assembly 10 and the transmission assembly 20 in the second driving mode of the present application. Figure 2 As shown, when the damping assembly 10 and the transmission assembly 20 of the present application are in the second driving mode, the transmission assembly 20 is also in the manual transmission state. Figure 2As shown, when the automatic transmission state is switched to the manual transmission state, the first mobile structure 210 rotates to the right side and abuts against the first limiting ring 630 to drive the moving member 600 to move to the left. During the movement, the third limiting structure 721 gradually disengages from the fourth limiting structure 722. Until the third limiting structure 721 completely disengages from the fourth limiting structure 722, due to the presence of the third driving member 820, the moving member 600 rotates to form a misalignment between the third limiting structure 721 and the fourth limiting structure 722. Further, due to the presence of the second driving member 710, the second driving member 710 drives the moving member 600 to move toward the rotating member 420, so that the third limiting structure 721 and the second limiting surface 610 abut. In this case, the animal to be transferred and the first connecting member 810 can be manually rotated, and then the rotating shaft 410 and the moving member 600 are rotated, so that the animal to be transferred forms an angle change. The manual transmission state refers to that the angle change of the animal to be transferred is driven manually, rather than driven by the first driving member 500. At the same time, during the movement, the first limiting ring 630 contacts the movable ring 140 and drives the damping unit 100 to move toward the first transmission part 712 on the fixed ring 711 until the second transmission part on the damping unit 100 is engaged with the first transmission part 712 on the fixed ring 711, and the second movable structure 220 is compressed. At this time, due to the misalignment between the third limiting structure 721 and the fourth limiting structure 722, the second transmission part on the damping unit 100 can be kept engaged with the first transmission part 712 on the fixed ring 711. Under this condition, the transmission assembly 20 can drive the damping core 130 to rotate, the transmission assembly 20 rotates in the reverse direction B, and the damping core 130 rotates in the forward direction A. At this time, the second limiting structure 320 cannot constrain the first limiting structure 310, and the damping core 130 rotates synchronously with the damping shell. When the damping core 130 rotates in the reverse direction B, the transmission assembly 20 rotates in the forward direction A. At this time, the second limiting structure 320 and the first limiting structure 310 constrain each other. At this time, the damping core 130 rotates in the damping shell and serves to slow down the rotation speed of the transmission assembly 20.

[0077] When the rotation angle of the object to be transmitted needs to be further increased in the manual transmission state, the object to be transmitted and the first connecting member 810 are continued to be manually rotated, and then the rotating shaft 410 and the moving member 600 are rotated, so that the rotation angle of the object to be transmitted is further increased until the third limiting structure 721 enters the fifth limiting structure 723. The fifth limiting structure 723 is provided to allow the user to have a certain perception ability during the manual rotation process, so as to remind the user that the object to be transmitted forms the maximum rotation angle after the third limiting structure 721 enters the fifth limiting structure 723. The extreme position state is an extreme case of the manual transmission state. In the present application, if it is necessary to switch the manual transmission state to the automatic transmission state, it is necessary to reversely rotate the animal B to be transmitted and the first connecting member 810 until the third limiting structure 721 and the fourth limiting structure 722 are correspondingly arranged. When the third limiting structure 721 and the fourth limiting structure 722 are correspondingly arranged, due to the existence of the second driving member 710, the second driving member directly drives the fourth limiting structure 722 and the third limiting structure 721 to form a self-locking. At this time, the second transmission part of the damping unit 100 and the first transmission part 712 of the transmission assembly 20 are always in a meshing state.

[0078] Attached Figure 1 This is a schematic diagram of a structure between the damping assembly 10 and the transmission assembly 20 of the present application in the first driving mode. Figure 1 As shown, the rotating shaft 410 is further rotated by the animal to be transmitted, and the moving member 600 is driven to rotate at the same time, until the third limiting structure 721 corresponds to the fourth limiting structure 722, and under the drive of the second elastic member 713, the fourth limiting structure 722 enters the third limiting structure 721 to enter the automatic transmission state. At this time, the moving member 600 moves toward the rotating member 420 at the same time, and the second limiting ring 640 and the moving ring 140 are against each other, and the second transmission part of the damping core 130 is separated from the first transmission part 712 on the fixed ring 711. Further, the second mobile structure 220 drives the damping unit 100 to move toward the limiting plate 650 until the moving ring 140 and the limiting plate 650 are against each other. At this time, the limiting plate 650 is located between the first limiting ring 630 and the second limiting ring 640, which can ensure that the moving ring 140 does not contact the first limiting ring 630 and the second limiting ring 640 when the transmission assembly 20 is automatically transmitted, thereby ensuring the stability of the transmission assembly 20 when it is automatically transmitted. Furthermore, the existence of the second movable structure 220 and the limiting plate 650 can ensure the relative stability of the position of the damping unit 100 in the second driving mode, thereby preventing the damping unit 100 from making a relative movement.
