Description

Technical Field

[0001] The present application relates to the technical field of electrophotographic imaging, and particularly relates to a coupling device, a processing cartridge, a coupling, and a rotating member. Background Art

[0002] In the related art, energy-consuming structures such as dampers are provided inside a printer. When the driving device of the printer drives the coupling, it will also drive the energy-consuming structure to rotate simultaneously. However, when the rotational speed of the energy-consuming structure is not synchronized with that of the coupling, it is easy to cause the connecting part between the coupling and the driving device to be deformed under force, resulting in easy damage to the coupling and high maintenance costs. Summary of the Utility Model

[0003] In view of this, the main purpose of the embodiments of the present application is to provide a coupling device, a processing cartridge, a coupling, and a rotating member with a low risk of damage.

[0004] To achieve the above object, the technical solution of the embodiments of the present application is implemented as follows:

[0005] A first aspect of the embodiments of the present application provides a coupling device for cooperating with a driving device, characterized in that the driving device includes an energy-consuming component, a connecting component, and a driving main body, and the energy-consuming component and the driving main body together form a clutch structure. In a state where the clutch structure is in an engaged state, the driving main body can drive the energy-consuming component to rotate;

[0006] The coupling device includes a coupling and a rotating member located on the coupling. One of the coupling and the rotating member is an active part, and the other is a driven part. The driven part has a joint surface and an abutting surface, and the abutting surface protrudes toward the side close to the driving device relative to the joint surface to form a pushing step. The energy-consuming component is rotatably arranged on the connecting component, and the connecting component has a connecting part;

[0007] When the connecting part abuts against the joint surface, the clutch structure is in the engaged state; when the connecting part switches to abut against the abutting surface, the driven part pushes the connecting part and the energy-consuming component to make the clutch structure in a disengaged state;

[0008] The driving main body is respectively drivingly connected to the active part and the connecting component, and the driving main body can drive the active part to rotate relative to the driven part within a set angle so that the connecting part switches between abutting against the abutting surface and the joint surface respectively.

[0009] In one implementation, the coupling includes a central shaft, the rotating member has a first connection hole, and the central shaft is movably inserted into the first connection hole.

[0010] In one embodiment, the rotating member is the driving part and the coupling is the driven part;

[0011] The coupling includes a pushing member that extends circumferentially around the central axis. A partial area on the side of the pushing member close to the driving device forms the engaging surface, and another partial area on the side of the pushing member close to the driving device protrudes to form the abutting surface; and / or,

[0012] On the pore wall of the first connection hole, a driving part with a driving surface is formed by protrusion. The driving body is in contact with the driving surface to drive the rotating member to rotate relative to the coupling within a set angle.

[0013] In one embodiment, the coupling is the driving part and the rotating member is the driven part;

[0014] The coupling includes a driving part with a driving surface. The driving part is arranged on the circumferential side of the central axis. The driving body is in contact with the driving surface; and / or,

[0015] A partial area on the outer end surface of the rotating member forms the engaging surface, and another partial area on the outer end surface of the rotating member protrudes to form the abutting surface.

[0016] In one embodiment, the coupling further includes a first convex block located on one side of the central axis along the circumferential direction. On the pore wall of the first connection hole of the rotating member, a second convex block is formed by protrusion. The first convex block and the second convex block are arranged at intervals along the circumferential direction of the central axis. The coupling device further includes a first elastic member arranged at the interval between the first convex block and the second convex block;

[0017] When the driving body drives the driving part to rotate, the first convex block and the second convex block move towards each other, so that the first elastic member is compressed, and the connecting part switches from abutting against the engaging surface to abutting against the abutting surface;

[0018] When the driving force of the driving body is withdrawn, the first elastic member rebounds, and the first convex block and the second convex block move away from each other, so that the connecting part switches from abutting against the abutting surface to abutting against the engaging surface.

[0019] In one embodiment, the driven part further has a guiding surface. One end of the guiding surface is connected to the engaging surface, the other end is connected to the abutting surface, and the guiding surface is inclined relative to the engaging surface and the abutting surface.

[0020] In one embodiment, the coupling device further includes an end cap and a retaining ring. The end cap has a receiving cavity, and the retaining ring has a second connection hole. The rotating member is rotatably disposed in the receiving cavity. The retaining ring is disposed on one side of the end cap to limit the axial movement of the rotating member. The central axis extends into the receiving cavity from the other side of the end cap to pass through the first connection hole and the second connection hole.

[0021] A second aspect of the embodiments of the present application provides a processing cartridge, which includes the coupling device according to any one of the above.

[0022] A third aspect of the embodiments of the present application provides a coupling, which is the coupling according to any one of the above.

[0023] A fourth aspect of the embodiments of the present application provides a rotating member, which is the rotating member according to any one of the above.

[0024] The embodiments of the present application provide a coupling device, a processing cartridge, a coupling, and a rotating member. One of the coupling and the rotating member of the coupling device is the driving part, and the other is the driven part. The driven part has a mating surface and an abutting surface. The abutting surface protrudes toward the side close to the driving device relative to the mating surface to form a pushing step. When the connecting part of the connecting assembly abuts against the mating surface, the clutch structure is in the engaged state. Thus, when the connecting part abuts against the mating surface, the driving body can drive the energy-consuming component to rotate while driving the coupling device to rotate, and the energy-consuming component can achieve a better energy-consuming effect during the rotation of the driving body. When the connecting part switches to abut against the abutting surface, the driven part pushes the connecting part and the energy-consuming component, so that the clutch structure is in the disengaged state. At the same time, since the energy-consuming component and the connecting assembly are rotatable, the driving body is separated from the energy-consuming component, and the driving body cannot continue to drive the energy-consuming component to rotate, and the energy-consuming component will not function. During this process, the driving body can still drive the coupling device to rotate, so there will be no problem of asynchronous rotation speed between the coupling device and the energy-consuming component. Furthermore, it will not cause the connecting part between the coupling device and the driving device to be easily deformed due to asynchronous rotation speed, so the damage risk of the coupling device can be reduced, and the maintenance cost of the coupling device can be reduced accordingly.

[0046] In the present application, the "axial" and "radial" orientation or positional relationship is based on the orientation or positional relationship shown in the appended Figure 15 figures. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present application.

[0047] The first embodiment of the present application provides a coupling device 10 for cooperating with a driving device 20. Please refer to Figure 1 , Figures 4 to 7 . The driving device 20 includes an energy-consuming component 21, a connection component 22 and a driving main body 23. The driving main body 23 is drivingly connected to the connection component 22. The energy-consuming component 21 and the driving main body 23 together form a clutch structure. In the engaged state of the clutch structure, the driving main body 23 can drive the energy-consuming component 21 to rotate.

[0048] Please refer to Figures 1 to 3, the coupling device 10 includes a coupling 11 and a rotating member 12 located on the coupling 11. One of the coupling 11 and the rotating member 12 is the driving part, and the other is the driven part. The driven part has a joint surface 11a and an abutting surface 11b. The abutting surface 11b protrudes towards the side close to the driving device 20 relative to the joint surface 11a to form a pushing step. The energy-consuming component 21 is rotatably arranged on the connecting component 22, and the connecting component 22 has a connecting portion 2221.

[0049] Please refer to Figures 14 to 19 , when the connecting portion 2221 abuts against the joint surface 11a, the clutch structure is in the engaged state; when the connecting portion 2221 switches to abut against the abutting surface 11b, the driven part pushes the connecting portion 2221 and the energy-consuming component 21 to make the clutch structure in the disengaged state;

[0050] The driving main body 23 is respectively drivingly connected to the driving part and the connecting component 22. The driving main body 23 can drive the driving part to rotate relative to the driven part within a set angle so that the connecting portion 2221 switches between abutting against the abutting surface 11b and the joint surface 11a respectively.

[0051] The second embodiment of the present application provides a processing cartridge, and the processing cartridge includes the coupling device 10 described in any embodiment of the present application.

[0052] The third embodiment of the present application provides an imaging device, and the imaging device includes the coupling device 10 described in any embodiment of the present application and a driving device 20. The driving device 20 is drivingly connected to the coupling device 10.

[0053] The fourth embodiment of the present application provides a coupling 11, and the coupling 11 is the coupling 11 described in any embodiment of the present application.

[0054] The fifth embodiment of the present application provides a rotating member 12, and the rotating member 12 is the rotating member 12 described in any embodiment of the present application.

[0055] Specifically, the imaging device can be any type of imaging device such as a printer, a copier, a fax machine, etc.

[0056] The coupling device 10 is used to connect the driving device 20 of the imaging device and the photosensitive drum cylinder 30. Thus, the driving device 20 can drive the coupling device 10 to rotate to drive the photosensitive drum cylinder 30 to rotate.

[0057] The energy-consuming component 21 of the driving device 20 is a device that can provide resistance to motion and consume motion energy. For example, the energy-consuming component 21 includes a damper 211.

[0058] The driving body 23 is the main structure of the driving device 20 for driving the coupling device 10 to rotate. For example, the driving body 23 includes a rotatable driving sleeve, and the energy-consuming component 21 and the connecting component 22 are arranged inside the driving sleeve. Of course, part of the regions of the energy-consuming component 21 and the connecting component 22 may extend outside the driving sleeve, or all regions may be located inside the driving sleeve.

[0059] The connecting component 22 is a part of the structure of the driving device 20 for docking with the coupling device 10. Its specific structure can be set according to the actual situation. For example, the connecting component 22 includes an outer claw 221 and an inner claw 222. The inner claw 222 and the outer claw 221 enclose an enclosed cavity 22a, and one end of the energy-consuming component 21 extends into the enclosed cavity 22a.

[0060] The energy-consuming component 21 and the driving body 23 together form a clutch structure, which means that at least part of the region of the energy-consuming component 21 can be combined with at least part of the region of the driving body 23 to form a clutch structure. The clutch structure refers to a combined structure with an engaged state and a disengaged state.

[0061] When the clutch structure is in the engaged state, the energy-consuming component 21 is engaged with the driving body 23, and the energy-consuming component 21 can rotate synchronously with the rotation of the driving body 23.

[0062] When the clutch structure is in the disengaged state, the energy-consuming component 21 is disengaged from the driving body 23, and the energy-consuming component 21 cannot rotate synchronously with the rotation of the driving body 23.

[0063] It should be noted that the specific structural form of the clutch structure is not limited.

[0064] Exemplarily, please refer to Figure 16 and Figure 19 , the energy-consuming component 21 includes a first protrusion 213, and the driving body 23 includes a second protrusion 231. When the energy-consuming component 21 is in contact with the driving body 23, at least part of the region of the first protrusion 213 and at least part of the region of the second protrusion 231 are in the same radial plane. Thus, when the driving body 23 rotates, the second protrusion 231 can abut against the first protrusion 213, so as to drive the energy-consuming component 21 to rotate by pushing the first protrusion 213. When the energy-consuming component 21 and the driving body 23 are axially separated, the first protrusion 213 and the second protrusion 231 are no longer in the same radial plane, thereby enabling the dislocation of the two, and further preventing the energy-consuming component 21 from rotating with the driving body 23.

[0065] One side of the coupling 11 is used to connect with the photosensitive drum cylinder 30, and the other side is used to install the rotating member 12 and connect with the driving device 20.

[0066] According to the actual situation, in some embodiments, the coupling 11 may be the driving part and the rotating part 12 may be the driven part. The rotating part 12 has a joint surface 11a and an abutting surface 11b. Of course, in other embodiments, the rotating part 12 may be the driving part and the coupling 11 may be the driven part. The coupling 11 has a joint surface 11a and an abutting surface 11b.

[0067] Both the joint surface 11a and the abutting surface 11b are docking surfaces on the side of the coupling device 10 close to the driving device 20, and are used for docking with the connecting part 2221 of the connecting component 22.

[0068] Among them, the abutting surface 11b protrudes towards the driving device 20 relative to the joint surface 11a. Thus, a height difference is formed between the abutting surface 11b and the joint surface 11a in the axial direction, that is, a pushing step is formed. The connecting part 2221 of the connecting component 22 can move on the pushing step.

[0069] The energy-consuming component 21 and the connecting component 22 can rotate relative to each other. The energy-consuming component 21 does not rotate synchronously with the connecting component 22, and the two are separated. That is to say, a clutch is not formed between the energy-consuming component 21 and the connecting component 22, or the clutch formed between the energy-consuming component 21 and the connecting component 22 is always in a disengaged state.

[0070] It should be noted that the specific way to achieve the separation between the energy-consuming component 21 and the connecting component 22 is not limited. For example, it can be achieved by removing the clutch between the energy-consuming component 21 and the connecting component 22.

[0071] Another example, please refer to Figure 16 and Figure 19 , the energy-consuming component 21 includes a third protrusion 214, and the connecting component 22 includes a fourth protrusion 223. When the energy-consuming component 21 and the connecting component 22 are connected to the coupling device 10, through the axial cooperation between the coupling device 10 and the connecting component 22, the fourth protrusion 223 and the third protrusion 214 are axially misaligned, thereby preventing the fourth protrusion 223 and the third protrusion 214 from jointly forming a clutch in the engaged state, and thus the purpose of preventing the energy-consuming component 21 from rotating synchronously with the connecting component 22 throughout the process can be achieved.

[0072] Since the joint surface 11a is recessed relative to the abutting surface 11b, through the axial height dimension cooperation, when the connecting part 2221 is docked with the joint surface 11a, the clutch structure can be in the engaged state. At the same time, since the abutting surface 11b protrudes relative to the joint surface 11a, when the connecting part 2221 is docked with the abutting surface 11b, the connecting part 2221 and the energy-consuming component 21 can be pushed, so that the energy-consuming component 21 is separated from the driving main body 23.

[0073] It should be noted that the driving body 23 is respectively drivingly connected to the connecting component 22 and the driving part, so that both the connecting component 22 and the driving part can rotate synchronously with the rotation of the driving body 23. Since the rotating part 12 is located on the coupling 11, the connection between the rotating part 12 and the coupling 11 is not an immovable connection, and the rotating part 12 can rotate relative to the coupling 11 by a set angle, that is, the driving part and the driven part can rotate by a set angle relative to each other. Thus, under the rotational drive of the driving body 23, the connecting component 22 and the driving part can be driven to rotate synchronously. Since the driving part and the driven part can rotate by a set angle relative to each other, relative rotation can be formed between the connecting component 22 and the driven part, that is, the connecting part 2221 can move relative to the pushing step, so that the connecting part 2221 can be switched between abutting against the abutting surface 11b and the joint surface 11a respectively, and further the clutch structure can be switched between the engaged state and the disengaged state.

[0074] It should be noted that in some embodiments, when the driving device 20 does not apply a driving force, the connecting part 2221 may abut against the joint surface 11a. As the driving body 23 gradually rotates, the connecting part 2221 moves to abut against the abutting surface 11b, and after the driving device 20 withdraws the driving force, the connecting part 2221 resets to abut against the joint surface 11a. It should be noted that in this embodiment, along the rotation direction of the connecting component 22, the joint surface 11a is located upstream of the abutting surface 11. That is, when the driving device 20 does not apply a driving force, the joint surface 11a is closer to the connecting part 2221 than the abutting surface 11.

[0075] Certainly, in other embodiments, when the driving device 20 does not apply a driving force, the connecting part 2221 may abut against the abutting surface 11b. As the driving body 23 gradually rotates, the connecting part 2221 moves to abut against the joint surface 11a, and after the driving device 20 withdraws the driving force, the connecting part 2221 resets to abut against the abutting surface 11b. It should be noted that in this embodiment, along the rotation direction of the connecting component 22, the abutting surface 11 is located upstream of the joint surface 11a. That is, when the driving device 20 does not apply a driving force, the abutting surface 11 is closer to the connecting part 2221 than the joint surface 11a.

[0076] Exemplarily, when the driving body 23 just starts to rotate, the connecting portion 2221 is at the joint surface 11a, and the clutch structure between the energy-consuming component 21 and the driving body 23 is in an engaged state. Thus, during the initial rotation of the driving body 23, the energy-consuming component 21 can be made to function, achieving a better energy-consuming effect. The driving body 23 drives the driving portion and the connecting assembly 22 to rotate synchronously, causing the driving portion to rotate a set angle relative to the driven portion, and causing the connecting portion 2221 to switch from abutting against the joint surface 11a to abutting against the joint surface 11a. Thus, the clutch structure switches from the engaged state to the disengaged state. After the driving portion rotates a set angle relative to the driven portion and abuts against the driven portion, the driven portion, the driving portion, and the connecting assembly 22 rotate synchronously, while the energy-consuming component 21 fails.

[0077] In summary, in the coupling device 10 of the embodiment of the present application, when the connecting portion 2221 abuts against the joint surface 11a, the driving body 23 can drive the energy-consuming component 21 to rotate while driving the coupling device 10 to rotate, enabling the energy-consuming component 21 to achieve a better energy-consuming effect during the rotation of the driving body 23. When the connecting portion 2221 switches to abutting against the abutting surface 11b, the driven portion pushes the connecting portion 2221 and the energy-consuming component 21, causing the clutch structure to be in a disengaged state. At the same time, since the energy-consuming component 21 and the connecting assembly 22 are rotatable relative to each other, the driving body 23 is separated from the energy-consuming component 21, and the driving body 23 cannot continue to drive the energy-consuming component 21 to rotate, and the energy-consuming component 21 will not function. During this process, the driving body 23 can still drive the coupling device 10 to rotate, so there will be no problem of asynchronous rotation speed between the coupling device 10 and the energy-consuming component 21. Furthermore, there will be no problem that the connecting portion 2221 of the coupling device 10 and the driving device 20 is easily deformed due to asynchronous rotation speed. Therefore, the damage risk of the coupling device 10 can be reduced, and the maintenance cost of the coupling device 10 can be further reduced.

[0078] In one embodiment, please refer to Figure 3 and Figure 13 , the coupling 11 includes a central shaft 111, and the rotating member 12 has a first connection hole 12a. The central shaft 111 is movably inserted into the first connection hole 12a. Thus, it is possible to facilitate the rotating member 12 to rotate a set angle relative to the coupling 11, and after rotating the set angle, it can push the coupling 11 to rotate synchronously.

[0079] In one embodiment, please refer to Figure 14 and Figure 17, the rotating member 12 is the active part, and the coupling 11 is the driven part. The coupling 11 includes a pushing member 112. The pushing member 112 extends circumferentially around the central axis 111. A partial area on the side of the pushing member 112 close to the driving device 20 forms a joint surface 11a, and another partial area on the side of the pushing member 112 close to the driving device 20 protrudes to form an abutting surface 11b.

[0080] Specifically, the connecting portion 2221 of the connecting assembly 22 is used to abut against the pushing member 112 of the coupling 11. The pushing member 112 is an arc-shaped structure extending circumferentially around the central axis 111. Thus, during the rotation of the connecting assembly 22, the connecting portion 2221 can move well along the joint surface 11a and the abutting surface 11b without disengaging from the pushing step.

[0081] In one embodiment, please refer to Figure 14 and Figure 17 , the rotating member 12 is the active part, and the coupling 11 is the driven part. A driving portion 121 with a driving surface 121a is formed by protruding on the hole wall of the first connecting hole 12a of the rotating member 12. The driving main body 23 is attached to the driving surface 121a to drive the rotating member 12 to rotate relative to the coupling 11 within a set angle.

[0082] Specifically, a partial area of the hole wall of the first connecting hole 12a protrudes to form the driving portion 121, and the driving main body 23 pushes the driving surface 121a of the driving portion 121, so as to achieve the purpose of driving the rotating member 12 to rotate by the driving main body 23.

[0083] In one embodiment, please refer to Figure 12 and Figure 13 , the coupling 11 is the active part, and the rotating member 12 is the driven part. The coupling 11 includes a driving portion 121 with a driving surface 121a. The driving portion 121 is arranged on the circumferential side of the central axis 111, and the driving main body 23 is attached to the driving surface 121a.

[0084] Specifically, by arranging the driving portion 121 on the circumferential side of the central axis 111 and the driving main body 23 pushing the driving surface 121a of the driving portion 121, the purpose of driving the coupling 11 to rotate by the driving main body 23 can be achieved.

[0085] In one embodiment, please refer to Figure 12 and Figure 13 , the coupling 11 is the active part, and the rotating member 12 is the driven part. A partial area of the outer end surface of the rotating member 12 forms a joint surface 11a, and another partial area of the outer end surface of the rotating member 12 protrudes to form an abutting surface 11b.

[0086] That is to say, a contact surface 11b is formed by protruding a partial area of the outer end surface of the rotating member 12, so that the connecting portion 2221 of the connecting assembly 22 is used to contact the contact surface 11b and the bonding surface 11a of the rotating member 12, and it can also enable the connecting portion 2221 to move well along the bonding surface 11a and the contact surface 11b without disengaging from the pushing step.

[0087] In one embodiment, please refer to Figure 14 and Figure 17 , the coupling 11 further includes a first convex block 113 located on one side of the central axis 111 in the circumferential direction. A second convex block 122 is formed by protruding on the hole wall of the first connection hole 12a of the rotating member 12. The first convex block 113 and the second convex block 122 are arranged at intervals in the circumferential direction of the central axis 111. The coupling device 10 further includes a first elastic member 24 arranged at the interval between the first convex block 113 and the second convex block 122.

[0088] When the driving main body 23 drives the driving portion to rotate, the first convex block 113 and the second convex block 122 move towards each other, so that the first elastic member 24 is compressed, and the connecting portion 2221 switches from contacting the bonding surface 11a to contacting the contact surface 11b.

[0089] When the driving main body 23 cancels the driving force, the first elastic member 24 rebounds, and the first convex block 113 and the second convex block 122 move away from each other, so that the connecting portion 2221 switches from contacting the contact surface 11b to contacting the bonding surface 11a. Thus, after the driving device 20 cancels the driving force, the energy-consuming component 21, the connecting assembly 22 and the driving portion can be reset, so that the clutch structure returns to the engaged state, facilitating the driving main body 23 to drive the coupling device 10 to rotate next time.

[0090] Specifically, the central axis 111 of the coupling 11 is movably inserted into the first connection hole 12a, and the rotating member 12 can rotate relative to the coupling 11 by a set angle. Among them, the specific angle range of the set angle depends on the interval distance between the first convex block 113 and the second convex block 122.

[0091] Actually, the rotating member 12 has an initial state and a contact state. When the rotating member 12 is in the initial state, the second convex block 122 is located at the initial position farthest from the first convex block 113, and the connecting portion 2221 contacts the bonding surface 11a. When the driving portion rotates by a set angle under the drive of the driving main body 23, the second convex block 122 moves relatively to the contact position closest to the first convex block 113, and the rotating member 12 switches to the contact state, and the connecting portion 2221 contacts the contact surface 11b. Thus, the driving main body 23 can drive the driving portion to push the driven portion to rotate synchronously. At this time, the first elastic member 24 is in a compressed state.

[0092] When the driving body 23 withdraws the driving force, under the action of the resilience of the first elastic member 24, the second bump 122 moves relatively to reset to the initial position, and the connecting portion 2221 resets to abut against the joint surface 11a.

[0093] It can be understood that the first elastic member 24 can be a spring or other elastic structures with elastic force.

[0094] In one embodiment, please refer to Figure 14 , the driven part further has a guiding surface 11c. One end of the guiding surface 11c is connected to the joint surface 11a, the other end is connected to the abutting surface 11b, and the guiding surface 11c is inclined relative to the joint surface 11a and the abutting surface 11b.

[0095] Specifically, the guiding surface 11c is an inclined surface located between the joint surface 11a and the abutting surface 11b. The guiding surface 11c has the function of guiding the movement of the connecting portion 2221. Thus, it is convenient for the connecting portion 2221 to switch between the joint surface 11a and the abutting surface 11b.

[0096] In one embodiment, please refer to Figure 3 , the coupling device 10 further includes an end cover 13 and a retaining ring 14. The end cover 13 has a receiving cavity 13a, the retaining ring 14 has a second connection hole 14a, the rotating member 12 is rotatably arranged in the receiving cavity 13a, the retaining ring 14 is arranged on one side of the end cover 13 to limit the axial movement of the rotating member 12, and the central axis 111 extends into the receiving cavity 13a from the other side of the end cover 13 to pass through the first connection hole 12a and the second connection hole 14a. Thus, while facilitating the connection between the connecting shaft and the driving device 20, the axial connection stability between the rotating member 12 and the coupling 11 can be improved.

[0097] Specifically, by providing the retaining ring 14, it can cooperate with the end cover 13 to limit the rotating member 12 in the receiving cavity 13a. At the same time, since the retaining ring 14 has a second connection hole 14a, the central axis 111 of the coupling 11 can pass through the first connection hole 12a and the second connection hole 14a to facilitate the connection with the driving device 20.

[0098] It should be noted that the specific connection method between the end cover 13 and the retaining ring 14 is not limited. For example, the end cover 13 and the retaining ring 14 can be connected by snap connection, bonding or by setting snap elements for fastening, etc.

[0099] In one embodiment, please refer to Figures 7 to 11The connecting component 22 includes an outer claw 221 and an inner claw 222 with a connecting portion 2221. The inner claw 222 and the outer claw 221 enclose an enclosed cavity 22a. The energy-absorbing component 21 includes a damper 211 and a connecting rod 212. One end of the connecting rod 212 is connected to the damper 211, and the other end of the connecting rod 212 extends into the enclosed cavity 22a and forms a clutch structure together with the driving body 23.

[0100] The driving device 20 further includes a second elastic member 25 and a third elastic member 26 . The second elastic member 25 is disposed between the outer claw 221 and the damper 211 , and the third elastic member 26 is disposed between the connecting rod 212 and the damper 211 .

[0101] When the driving body 23 cancels the driving force, the connecting portion 2221 moves to abut against the joint surface 11a under the action of the second elastic member 25, and the connecting rod 212 is engaged with the driving body 23 under the action of the third elastic member 26. Therefore, when the driving device 20 cancels the driving force, it is easy to reset the connecting component 22 and the energy consumption component 21.

[0102] Specifically, the connecting rod 212 mainly plays a connecting role, and can be connected to the driving body 23 to form a clutch structure. In addition, one end of the connecting rod 212 away from the damper 211 extends into the enclosed cavity 22a, and the connecting rod 212 can rotate relative to the outer claw 221.

[0103] It should be noted that the active portion may also be provided with an outer claw guide surface 11 c , thereby being able to guide the movement of the outer claw 221 .

[0104] In a specific embodiment, the connection assembly 22 includes an outer claw 221 and an inner claw 222, and a portion of the outer claw 221 extends toward one side of the coupling device 10 to form a connection portion 2221. That is, in this embodiment, the connection portion 2221 is formed by the outer claw 221, and then the outer claw 221 is driven to rotate by the driving body 23 to drive the connection portion 2221 to switch between abutting against the joint surface 11a and abutting against the abutting surface 11b. In this way, the outer claw 221 can be used to cooperate with the coupling device 10.
