Description

Technical Field

[0002] A processing cartridge is a consumable that is detachably installed in an electrophotographic imaging device (hereinafter referred to as "device"). It is provided with at least one rotating component for stirring toner stored in the processing cartridge, forming an electrostatic latent image on its surface, or carrying toner to supply to the component forming the electrostatic latent image, etc.

[0003] Regardless of the function of the rotating component, it needs to receive driving force from the device when the processing box is imaging. Generally, the driving force output component in the device includes a rotating shaft on the device side and multiple force output protrusions on the rotating shaft. The processing box contains a driving force receiver, which has multiple claws for engaging with the force output protrusions. In this way, the driving force output component can output driving force to the driving force receiver. However, in actual operation, during the installation of the processing box along the installation direction, the driving force receiver is prone to interference with the driving force output component. Similarly, during the disassembly of the processing box, the driving force receiver is also prone to interference with the driving force output component, causing damage to the driving components and increasing the difficulty of installing / disassembling the processing box.

Detailed Implementation

[0032] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0033] [Overall structure of the processing box]

[0034] like Figure 1 As shown, the processing box C can be detachably installed onto a device equipped with a device-side action device 90. The device-side action device 90 includes adjacent and spaced-apart device-side action blocks 91 and a driving force output member 92. The driving force output member 92 includes a device-side rotation shaft 921 and a force output protrusion 922, wherein the force output protrusion 922 protrudes from the device-side rotation shaft 921. For example, two force output protrusions 922 are radially opposite to each other on the outer surface of the device-side rotation shaft 921.

[0035] The processing cartridge C includes at least one of a first unit 100 and a second unit 200. The first unit 100 includes a first housing 11 and a developing roller 12 rotatably disposed in the first housing 11. The developing roller 12 is used to carry toner contained in the first housing 11. The second unit 200 includes a second housing 21 and a photosensitive drum 22 rotatably disposed in the second housing 21. Therefore, the first unit 100 is also referred to as a developing unit, the first housing 11 is also referred to as a developing housing, the second unit 200 is also referred to as a drum unit, and the second housing 21 is also referred to as a drum housing. The photosensitive drum 22 is arranged opposite to the developing roller 12. When the processing cartridge C performs imaging, the two can either contact each other or be spaced apart. The surface of the photosensitive drum 22 is used to form an electrostatic latent image. The developing roller 12 supplies the toner carried on its surface to the photosensitive drum 22, so that the electrostatic latent image is developed.

[0036] Furthermore, the processing box C also includes a driving force receiving component 30 for receiving driving force from the device. The developing roller 12 and the photosensitive drum 22 are directly or indirectly driven by the driving force receiving component 30 to rotate about their respective rotation axes. That is, the driving force receiving component 30 can be disposed in either the first unit 100 or the second unit 200.

[0037] For ease of description, the direction of the rotation axis of the developing roller 12 or the rotation axis of the photosensitive drum 22 is defined as the longitudinal direction. Along the longitudinal direction, the side where the driving force receiving component 30 is located is the driving side, and the side opposite to the driving side is the non-driving side. The direction from the driving side to the non-driving side is left, and the opposite is right. The direction intersecting the longitudinal direction is the transverse direction. Along the transverse direction, the processing box C is installed forward into the device and removed backward from the device.

[0038] The following description takes the example of the driving force receiving component 30 being set in the second unit 200 and the driving force receiving component 30 directly driving the photosensitive drum 22. In this case, the driving force receiving component 30 will be coaxial with the photosensitive drum 22, or the driving force receiving component 30 will directly engage with the photosensitive drum 22 to transmit driving force.

[0039] In some embodiments, the rotation axis of the drive force receiving component 30 may be parallel to the rotation axis of the photosensitive drum 22.

[0040] As described above, the processing cartridge C includes at least one of a first unit 100 and a second unit 200. Therefore, the processing cartridge C can be simplified to include a housing and a rotating member rotatably disposed in the housing. The housing is at least one of a first housing 11 and a second housing 21, and the rotating member is at least one of a developing roller 12 and a photosensitive drum 22. The driving force receiving assembly 30 and the rotating member are collectively referred to as the rotating assembly.

[0041] It should be understood that the rotating component may also be a toner feeding roller or a stirring frame rotatably disposed in the first housing 11, the stirring frame being used to stir the toner contained in the first housing 11, the toner feeding roller contacting the developing roller 12, and the toner feeding roller being used to supply toner toward the developing roller 12; the rotating component may also be a charging roller rotatably disposed in the second housing 21, the charging roller contacting the photosensitive drum 22, and being used to charge the surface of the photosensitive drum 22. Therefore, the rotating component should be understood as a component rotatably disposed in the housing, which can be directly / indirectly driven by the driving force received from the driving force receiving assembly 30.

[0042] Furthermore, the processing box C also includes an end cap 13, a handle 15, and a bearing plate 23. The end cap 13 is fixedly connected to the housing (first housing 11) and is used to protect the components in the processing box C (e.g., the gear set that transmits driving force inside the processing box). The handle 15 is disposed on the housing (first housing 11), and the user can install or remove the processing box C by gripping the handle 15. In the longitudinal direction, the end cap 13 is disposed on the same side as the driving force receiving assembly 30. The bearing plate 23 is fixedly mounted on the housing (second housing 21), and in the longitudinal direction, a portion of the driving force receiving assembly 30 passes through the bearing plate 23.

[0043] like Figure 3A As shown, the bearing plate 23 includes a plate body 231, a through hole 232, a first positioning part 233, and a second positioning part 234. The bearing plate 23 is fixedly mounted on the housing (second housing 21) through the plate body 231. The driving force receiving member 32 passes through the through hole 232, so that at least the driving body 322 is exposed outside the plate body 231. The first positioning part 233 is used to position and guide the control member 342, and the second positioning part 234 is used to position the force applying member (lifting member) 341, so that the clutch member 33 can rotate relative to the lifting member 341.

[0044] [Drive Force Receiving Component]

[0045] (Example 1)

[0046] like Figure 2 , Figure 3A , Figure 3B , Figure 4A and Figure 4B As shown, the driving force receiving assembly 30 includes a hub 31, a driving force receiving element 32, a clutch element 33, and a control mechanism 34. The driving force receiving element 32 is used to engage with the driving force output element 92 to receive driving force. The hub 31 is used to transmit the driving force received by the driving force receiving element 32. For example, the hub 31 directly transmits the driving force to the rotating element. The clutch element 33 is disposed between the driving force receiving element 32 and the hub 31 and is configured to move between a transmission position and a disconnection position. In the transmission position, the driving force receiving element 32 and the hub 31 transmit force through the clutch element 33. In the disconnection position, the driving force receiving element 32 and the hub 31 cannot transmit force through the clutch element 33. The control mechanism 34 is used to control the clutch element 33 to switch between the transmission position and the disconnection position.

[0047] The hub 31 is configured as a cylindrical body, including a cylindrical body 311, a driving force transmission part 312, and a driven part 313. The cylindrical body 311 has an internal movable cavity 314. The driven part 313 is disposed in the movable cavity 314 and is used to receive driving force from the clutch 33. The driving force transmission part 312 is used to transmit the driving force received by the driven part 313. For example, when the driving force receiving assembly 30 is coaxially arranged with the photosensitive drum 22, the cylindrical body 311 can directly transmit the driving force received by the driven part 313 to the photosensitive drum 22. The driving force transmission unit 312 can transmit the driving force to other components. When the driving force receiving component 30 is not coaxial with the photosensitive drum 22, the driving force receiving unit 312 can transmit the driving force to the photosensitive drum 22. A part of the driving force receiving component 32, at least a part of the clutch component 33, and a part of the control mechanism 34 are all located in the movable cavity 314. It can be seen that the driving force receiving component 30 can be used as a whole independently of the rotating component. Therefore, the driving force receiving component 30 has a certain degree of versatility.

[0048] The driving force receiving component 32 includes a shaft 321 and a driving body 322 connected to each other, or the shaft 321 and driving body 322 can be integrally formed. The shaft 321 is connected to the clutch 33 in a force-transmitting manner, for example, the shaft 321 and the clutch 33 are fixedly connected, or the shaft 321 and the clutch 33 are movably connected along the axial direction. Therefore, the shaft 321 / driving force receiving component 32 and the clutch 33 can move together in the longitudinal direction, or the clutch 33 can move relative to the shaft 321 in the longitudinal direction. Preferably, in this embodiment, the clutch 33 is designed to... The drive body 322 is designed to move longitudinally relative to the shaft 321. It includes a chassis 3221 and multiple drive force receiving units 3222 mounted on the chassis 3221. The chassis 3221 is connected to the shaft 321. In the longitudinal direction, the drive force receiving units 3222 extend from the chassis 3221 away from the shaft 321 to engage with the drive force output unit 922 to receive drive force. Therefore, the drive force receiving units 3222 and the shaft 321 are located on opposite sides of the chassis 3221. At least one drive force receiving unit 3222 is provided. Figure 3A and Figure 3B As shown, two drive force receiving parts 3222 are arranged opposite each other in the radial direction of the chassis 3221. Along the rotation direction of the drive force receiving member 32, or in other words, along the circumferential direction / rotation direction of the drive force receiving member 32, an inlet 3223 is formed between two adjacent drive force receiving parts 3222 to allow the drive force output member 92 / equipment-side rotating shaft 921 to enter.

[0049] The clutch 33 includes a first body 331 and an active part 332 and a mating part 333 disposed on the first body 331. The first body 331 is used to cooperate with the shaft 321. Along the rotation direction of the driving force receiving member 32, the first body 331 and the shaft 321 can transmit force, or in other words, the clutch 33 and the driving force receiving member 32 can transmit force. The active part 332 is used to transmit driving force, and the mating part 333 is used to cooperate with the control mechanism 34. In the transmission position, along the rotation direction of the driving force receiving member 32, the active part 332... At least a portion of the active part 332 is opposite to / overlaps with at least a portion of the driven part 313, so that force can be transmitted between the active part 332 and the driven part 313. In the disconnected position, along the rotation direction of the driving force receiver 32, the active part 332 and the driven part 313 are not opposite to / overlap, so that force cannot be transmitted between the active part 332 and the driven part 313. In this embodiment, both the active part 332 and the driven part 313 are provided as protrusions. Preferably, along the longitudinal direction, the driven part 313 is provided near the left end of the cylinder 311.

[0050] The control mechanism 34 includes a force-applying component (a lifting component in this embodiment) 341, a control component 342, and a reset component 343. The lifting component 341 is connected to both the clutch component 33 and the control component 342. Specifically, the lifting component 341 includes a second body 3411, a mating part 3412, and a positioning part 3413. The mating part 3412 and the positioning part 3413 are both connected to or integrally formed with the second body 3411. The mating part 3412 is used to engage with the clutch component 342. The mating part 333 provided in section 3 cooperates to restrict the lifting member 341 and the clutch member 33 in the longitudinal direction; the positioning part 3413 is configured to protrude from the second body 3411, specifically as a protrusion extending toward the driving force receiving part 3222, for cooperating with the second positioning part 234 other than the control mechanism 34 to restrict the lifting member 341 from rotating along the rotation direction of the driving force receiving part 32, that is, the lifting member 341 and the clutch member 33 can rotate relative to each other.

[0051] The control element 342 is configured as a flexible element for connecting with the lifting element 341 and interacting with the driving force receiving element 32. In one embodiment, the first positioning part 233 is configured as a through hole penetrating the plate 231 in the longitudinal direction. The control element 342 passes through the first positioning part 233 and is positioned. At the same time, the control element 342 can also be guided by the first positioning part 233.

[0052] The control element 342 includes a third body 3420, a first end 3421, a second end 3422, and an action part 3423. The first end 3421 and the second end 3422 are located at opposite ends of the third body 3420 / control element 342. The first end 3421 receives an external force that compels the control element 342 to move. The second end 3422 connects to a lifting member 341, allowing the external force to be transmitted to the lifting member 341. Through the engagement of the mating part 333 and the mated part 3412, the clutch 33 also moves with the lifting member 341. The action part 3423 is configured to move in sync with the movement of the third body 3420. The action part 3423 can be either part of the third body 3420 or a component connected to the third body 3420. When an external force is applied to the control element 342, the action part 3423 is driven by the external force and interacts with the driving force receiving member 32. The friction between the components 32 causes the driving force receiving component 32 to rotate by a certain angle to avoid or reduce interference between the driving force receiving component 32 and the driving force output component 92. More specifically, it avoids or reduces interference between the driving force receiving part 3222 and the force output protrusion 922, thereby making the driving force receiving component 32 and the driving force output component 92 more smoothly engage or disengage. The reset component 343 is used to force the clutch component 33 to move along the longitudinal direction / rotation axis L1 of the driving force receiving component 32, so that the clutch component 33 returns from the transmission position to the disengagement position, or from the disengagement position to the transmission position. The direction of the reset force applied by the reset component 343 to the clutch component 33 is opposite to the direction of the force applied by the action force to the clutch component 33. In this embodiment, the action force is used to force the clutch component 33 to move from the transmission position to the disengagement position, and the reset component 343 is used to force the clutch component 33 to return from the disengagement position to the transmission position. Therefore, the reset component 343 is set as an elastic component that directly or indirectly contacts the clutch component 33.

[0053] In this embodiment, the functional part 3423 is configured as part of the third main body 3420, such as Figure 3A and Figure 3B As shown, a portion of the third body 3420 is wound around the shaft 321 of the driving force receiver 32 as the working part 3423. The reset member 343 is configured as a compression spring with one end in contact with the lifting member 341, and the other end of the reset member 343 is in contact with the driving force receiver 32.

[0054] In some implementations, the control element 342 may be configured as an elastic cord.

[0055] In some embodiments, the other end of the reset member 343 may also contact the bearing plate 23.

[0056] In some embodiments, the reset member 343 may also be configured as a tension spring with one end in contact with the clutch member 33, in which case the other end of the reset member 343 will contact the cylinder 311 or the shell.

[0057] In some embodiments, the actuating part 3423 may not need to be wound around the shaft 321. As long as the actuating part 3423 contacts the shaft 321, the friction between the two is sufficient to make the driving force receiving member 32 rotate. For example, the surface of the actuating part 3423 or the surface of the shaft 321 is set as a rough surface, or the surface of the actuating part 3423 or the surface of the shaft 321 is covered with a component that can generate friction, such as rubber or sponge.

[0058] In some implementations, the first end 3421 can be pulled directly by the user's hand, that is, the force is the pulling force applied by the user's hand to the control 342.

[0059] In some embodiments, the first end 3421 may also be connected to a handle 15, which is configured to be movable relative to the housing. When a user grips the handle 15 to install or remove the processing box C, a force can be applied to the first end 3421 as the handle 15 moves.

[0060] In some embodiments, the force may also come from the imaging device. For example, the first end 3421 is connected to the door cover of the imaging device, and the first end 3421 is pulled by the door cover during the opening or closing process.

[0061] In some embodiments, the processing box C is also provided with a guide portion 14 for guiding the control member 342. For example, the guide portion 14 is configured as a groove formed on the end cap 13, and a part of the control member 342 is guided by the groove to control the movement trajectory of the control member 342, and also to enable the force to be effectively transmitted in the control member 342.

[0062] The following is combined with Figure 4A and Figure 4B Describe the process of the drive force receiving component 30 / drive force receiving element 32 and drive force output element 92 being combined with each other.

[0063] like Figure 4A As shown, before the drive force receiving assembly 30 / drive force receiving element 32 and drive force output element 92 begin to engage, the clutch 33 is in the transmission position. For the drive force receiving element 32, the position of the drive force receiving part 3222 will be random. Therefore, along the installation direction, the drive force receiving element 32 / inlet 3223 and the equipment-side rotating shaft 921 may have the following two positional relationships:

[0064] In the first position, the inlet 3223 is not opposite to the rotating shaft 921 on the device side; in other words, the driving force receiving part 3222 is opposite to the rotating shaft 921 on the device side. The position of the driving force receiving part 3222 in this case can be referenced... Figure 4B The driving force receiving component 30 / driving force receiving element 32 will interfere with the driving force output element 92.

[0065] In the second position, the inlet 3223 is opposite to the rotating shaft 921 on the equipment side, or in other words, the driving force receiving part 3222 is not opposite to the rotating shaft 921 on the equipment side. Figure 4A As shown, the driving force receiving component 30 / driving force receiving element 32 will not interfere with the driving force output element 92.

[0066] In the second position described above, the processing box C can be installed smoothly, and the driving force receiving component 30 / driving force receiving element 32 and the driving force output element 92 can be successfully combined.

[0067] In the first position described above, the control member 342 moves upon receiving an external force. The second end 3422 of the control member 342 pulls the lifting member 341. Through the engagement of the mating part 333 and the mated part 3412, the lifting member 341 drives the clutch member 33 to move from the transmission position to the disengagement position. At this time, the driving force receiving member 32 will be able to rotate freely, and the reset member 343 will undergo elastic deformation. As the processing box C is further installed, even if the driving force receiving member 32 and the driving force output member 92 interfere with each other, the driving force output member 92 applies a thrust to the driving force receiving member 32 that is opposite to the installation direction of the processing box C. Under the action of this thrust, the driving force receiving member 32 can rotate to the second position, or in other words, under the action of this thrust, the driving force receiving member 32 rotates to a position that allows the driving force receiving member 32 and the driving force output member 92 to engage smoothly, and the processing box C can be installed smoothly.

[0068] Furthermore, when the control component 342 receives an external force, the action part 3423 will also rub against the driving force receiving component 32, causing the driving force receiving component 32 to rotate at a certain angle, so that the driving force receiving component 32 directly reaches the second position. Then, during the installation of the processing box C, the driving force receiving component 32 will no longer interfere with the driving force output component 92. That is to say, the driving force receiving component 32 will no longer receive the thrust, so that the processing box C can be installed more smoothly.

[0069] When the control element 342 no longer receives external force, the reset element 343 releases the reset force, the clutch element 33 returns from the disconnected position to the transmission position, the driving force receiving element 32 and the driving force output element 92 engage with each other, and as the driving force output element 92 outputs driving force to the driving force receiving element 32, the driving force is transmitted to the cylinder 311 in sequence through the driving force receiving element 32, the active part 332 on the clutch element 33 and the driven part 313 on the hub 31.

[0070] Conversely, when the processing box C needs to be removed from the device, the inlet 3223 and the device-side rotating shaft 921 may also have the above two positional relationships along the installation direction. Obviously, in the second position, the driving force receiving member 32 and the driving force output member 92 can be smoothly disengaged, and the processing box C can be smoothly removed from the device.

[0071] In the first position described above, the user can also apply an external force to the control unit 342, causing the clutch unit 33 to move from the transmission position to the disengagement position. At this time, the drive force receiving unit 32 will be able to rotate freely, and the reset unit 343 will undergo elastic deformation. Even if the drive force receiving unit 32 and the drive force output unit 92 interfere with each other, the drive force receiving unit 32 can still rotate to the second position, or in other words, the drive force receiving unit 32 can rotate to a position that allows the drive force receiving unit 32 and the drive force output unit 92 to disengage smoothly, and the processing box C can be smoothly removed.

[0072] When the control element 342 no longer receives external force, the reset element 343 releases the reset force, and the clutch element 33 returns from the disengaged position to the transmission position.

[0073] (Example 2)

[0074] like Figure 5 As shown, the control unit 342 in this embodiment includes a first control part 342a and a second control part 342b formed separately. The first control part 342a is used to control the clutch 33 to move from the transmission position to the disengagement position, and the second control part 342b is used to contact the driving force receiving member 32 and generate friction force, thereby controlling the rotation of the driving force receiving member 32.

[0075] The first control unit 342a includes a first control unit body 3420a, a first end 3421, and a second end 3422, with the first end 3421 and the second end 3422 located at opposite ends of the first control unit body 3420a. The second control unit 342b includes a second control unit body 3420b, an action part 3423, and a third end 3424, with the action part 3423 and the third end 3424 located at opposite ends of the second control unit body 3420b. In this embodiment, the third body 3420 will include the first control unit body 3420a and the second control unit body 3420b. Similarly, the action part 3423 is used to contact the driving force receiving member 32. When the third end 3424 receives an external force, friction is generated between the action part 3423 and the driving force receiving member 32. Under the action of this friction, the driving force receiving member 32 rotates by a certain angle.

[0076] As described above, when the clutch 33 is in the disengaged position, the drive force receiver 32 can rotate freely. When the drive force receiver 32 receives a thrust from the drive force output member 92, the drive force receiver 32 will be able to rotate to the second position under the action of the thrust, or in other words, the drive force receiver 32 will rotate to a position that allows the drive force receiver 32 and the drive force output member 92 to engage smoothly under the action of the thrust. It can be seen that even if the actuating part 3423 does not need to interact with the drive force receiver 32, the drive force receiver 32 can still engage smoothly with the drive force output member 92. That is to say, the control mechanism 34 is at least used to control the clutch 33 to switch between the transmission position and the disengagement position.

[0077] Alternatively, with the clutch 33 in the disengaged position, if the inlet 3223 is also in the first position, the user can also rotate the drive force receiver 32 to the second position by operating the control unit 342 (second control unit 342b) before the drive force receiver 32 and the drive force output unit 92 come into contact with each other. In this way, the drive force receiver 32 and the drive force output unit 92 can be engaged more smoothly.

[0078] In this embodiment, the control unit 342 is configured to include the first control unit 342a and the second control unit 342b. On the one hand, this helps to reduce the external force required by each control unit. On the other hand, it can prevent the user from operating the second control unit 342b, causing the driving force receiving unit 32, which was originally in the second position, to be driven by the frictional force to rotate to the first position.

[0079] (Example 3)

[0080] In the above embodiment, before the driving force receiving component 32 and the driving force output component 92 are engaged, the clutch component 33 is in the transmission position. When the control component 342 receives an external force, the clutch component 33 is pulled by the control component 342 and moves to the right in the longitudinal direction. The clutch component 33 moves from the transmission position to the disengagement position, and the reset component 343 undergoes elastic deformation. The driving force receiving component 32 and the driving force output component 92 can be smoothly engaged. When the control component 342 no longer receives an external force, the reset component 343 releases the reset force, and the clutch component 33 returns from the disengagement position to the transmission position.

[0081] Unlike the above embodiments, the transmission and disconnection positions of the driving force receiving component 32 are changed in this embodiment. Specifically, before the driving force receiving component 32 engages with the driving force output component 92, the clutch component 33 is in the disconnected position. Therefore, the driving force receiving component 32 and the driving force output component 92 can be smoothly engaged. Subsequently, under the action of the external force received by the control component 342, the clutch component 33 moves to the right in the longitudinal direction. The clutch component 33 moves from the disconnected position to the transmission position, and the driving force receiving component 32 can transmit the driving force output by the driving force output component 92 to the cylinder 311.

[0082] In this embodiment, in order for the clutch 33 to remain in the transmission position, the control element 342 needs to remain in the state of receiving external force. For this purpose, a holding mechanism can be provided on the control element 342 or the housing, so that the control element 342 remains in the state of receiving external force after being pulled directly by the user or pulled by the handle 15 or other means.

[0083] In some embodiments, the external force may also come from the door cover of the device. As the door cover closes, the door cover applies an external force to the control member 342. When the door cover is closed, the control member 342 is held by the door cover in the state of receiving the external force. Therefore, the door cover can also be regarded as a type of holding mechanism.

[0084] like Figure 6 As shown, compared to the position of the driven part 313 in the cylinder 311 in the above embodiment, the driven part 313 in this embodiment will be closer to the right end of the cylinder 311 in the longitudinal direction, so that the driven part 313 can cooperate with the active part 332 in the clutch 33 after being pulled to the right.

[0085] When the control unit 342 in this embodiment is configured the same as in Embodiment 2, when the clutch 33 is in the transmission position, it is only necessary to ensure that the first end 3421 remains in the state of receiving external force, and the second control unit 342b does not need to receive external force. When the clutch 33 is in the disengaged position, in one embodiment, neither the first control unit 342a nor the second control unit 342b needs to receive external force. Even if there is interference between the driving force receiving unit 32 and the driving force output unit 92, since the driving force receiving unit 32 can rotate freely, the driving force receiving unit 32 can also be smoothly disengaged from the driving force output unit 92. In another embodiment, the first control unit 342a does not need to receive external force, but the second control unit 342b can receive external force, so that the driving force receiving unit 32 rotates a certain angle to reach the second position.

[0086] (Example 4)

[0087] Unlike the embodiments described above, the functional part 3423 in this embodiment is configured as a component different from the third main body 3420, such as... Figure 7 As shown, in this embodiment, the actuating part 3423 is configured as a friction member mounted on the third body 3420 (second control body 3420b). Compared with the third body 3420 (second control body 3420b), the contact area between the actuating part 3423 and the driving force receiving member 32 is larger. Correspondingly, the friction force generated between the actuating part 3423 and the driving force receiving member 32 is also greater. Thus, the driving force receiving member 32 can be driven more easily, or the driving force receiving member 32 can rotate at a larger angle.

[0088] (Example 5)

[0089] Unlike the above embodiments, the driving force receiving component 32 in this embodiment is configured to extend and retract along its rotation axis L1. In addition, in this embodiment, the action part 3423 of the control member 342 is located on the first protrusion 235 of the bearing plate 23 or on the outside of the first protrusion 235.

[0090] Specifically, such as Figures 8 to 12A , Figure 12BAs shown, the driving force receiving assembly 30 includes a hub 31, a driving force receiving element 32, a clutch element 33, and a control mechanism 34. The driving force receiving element 32 is used to engage with the driving force output element 92 to receive driving force. The hub 31 is used to transmit the driving force received by the driving force receiving element 32. For example, the hub 31 directly transmits the driving force to the rotating element. The clutch element 33 is disposed between the driving force receiving element 32 and the hub 31 and is configured to move between a transmission position and a disconnection position. In the transmission position, the driving force receiving element 32 and the hub 31 transmit force through the clutch element 33. In the disconnection position, the driving force receiving element 32 and the hub 31 cannot transmit force through the clutch element 33. The control mechanism 34 is used to control the clutch element 33 to switch between the transmission position and the disconnection position.

[0091] The hub 31 is configured as a cylindrical body, including a cylindrical body 311, a driving force transmission part 312, and a driven part 313. The cylindrical body 311 has an internal movable cavity 314. The driven part 313 is disposed in the movable cavity 314 and is used to receive driving force from the clutch 33. The driving force transmission part 312 is used to transmit the driving force received by the driven part 313. For example, when the driving force receiving assembly 30 is coaxially arranged with the photosensitive drum 22, the cylindrical body 311 can directly transmit the driving force received by the driven part 313 to the photosensitive drum 22. The driving force transmission unit 312 can transmit the driving force to other components. When the driving force receiving component 30 is not coaxial with the photosensitive drum 22, the driving force receiving unit 312 can transmit the driving force to the photosensitive drum 22. A part of the driving force receiving component 32, at least a part of the clutch component 33, and a part of the control mechanism 34 are all located in the movable cavity 314. It can be seen that the driving force receiving component 30 can be used as a whole independently of the rotating component. Therefore, the driving force receiving component 30 has a certain degree of versatility.

[0092] The driving force receiving component 32 includes a shaft 321 and a driving body 322 connected to each other, or the shaft 321 and driving body 322 can be integrally formed, such as... Figure 9BAs shown, the shaft 321 and the clutch 33 are connected in a force-transmitting manner. Preferably, the shaft 321 and the clutch 33 are engaged with each other in the axial direction. Therefore, the shaft 321 / driving force receiver 32 and the clutch 33 can move together in the longitudinal direction. The shaft 321 / driving force receiver 32 and the clutch 33 can also rotate together around the rotation axis L1 of the driving force receiver 32. The end of the shaft 321 away from the drive body 322 is accommodated by the movable cavity 314 of the hub 31. The drive body 322 includes a chassis 3221. A plurality of drive force receiving parts 3222 are disposed on the chassis 3221, which is connected to the shaft 321. Along the longitudinal direction, the drive force receiving parts 3222 extend from the chassis 3221 in a direction away from the shaft 321 to engage with the drive force output part 922 to receive drive force. Therefore, the drive force receiving parts 3222 and the shaft 321 are respectively located on both sides of the chassis 3221. At least one drive force receiving part 3222 is provided; in this embodiment, two drive force receiving parts 3222 are preferred. Figure 9A and Figure 9B As shown, two drive force receiving parts 3222 are arranged radially opposite each other along the chassis 3221. Along the rotation direction of the drive force receiving member 32, or in other words, along the circumferential direction / rotation direction of the drive force receiving member 32, an inlet 3223 is formed between adjacent drive force receiving parts 3222 to allow the drive force output member 92 / equipment-side rotating shaft 921 to enter. In other embodiments, the shaft 321 and the clutch member 33 can also be configured as a fixed connection / integral molding.

[0093] The clutch 33 includes a first body 331 and an active part 332 and a mating part 333 disposed on the first body 331. The first body 331 is used to engage with the shaft 321. Along the rotation direction of the driving force receiving member 32, the first body 331 and the shaft 321 can transmit force, or in other words, the clutch 33 and the driving force receiving member 32 can transmit force. The active part 332 is used to transmit driving force. In the transmission position, along the rotation direction of the driving force receiving member 32, at least a portion of the active part 332 is opposite to / overlaps with at least a portion of the driven part 313, thus, force can be transmitted between the active part 332 and the driven part 313. In the disengagement position, along the rotation direction of the driving force receiving member 32, the active part 332 and the driven part 313 are not opposite to / overlap, thus, force cannot be transmitted between the active part 332 and the driven part 313. In this embodiment, both the active part 332 and the driven part 313 are configured as protrusions. Preferably, such as... Figure 11 As shown, the driven part 313 extends along the inner wall of the cylinder 311 in the left-right direction along the longitudinal direction.

[0094] like Figure 9BAs shown, the mating part 333 is used to engage with the shaft 321 of the driving force receiver 32. Preferably, in this embodiment, the mating part 333 is a protrusion, and the shaft 321 is provided with a groove that engages with the protrusion. The clutch 33 is also provided with a limiting protrusion 334, which is used to prevent the shaft 321 of the driving force receiver 32 from shifting radially, thereby improving the accuracy of the engagement between the driving force receiver 32 and the driving force output member 92.

[0095] Furthermore, the active part 332 of the clutch 33 and the driven part 313 of the hub 31 can be a protrusion and groove fit, or other fit methods such as snap-fit, as long as force transmission can be achieved. Furthermore, the driven part 313 is provided in at least one place, preferably, the driven part 313 is provided in four places evenly distributed.

[0096] The control mechanism 34 includes a force-applying component (a pressing component in this embodiment) 341, a control component 342, and a reset component 343. In this embodiment, the pressing component 341 and the control component 342 are integrally formed. Optionally, the pressing component 341 and the control component 342 can also be separately formed. Specifically, the pressing component 341 includes a second body 3411 and a positioning part 3413. The positioning part 3413 is used to connect the control component 342 and the second body 3411. The positioning part 3413 is connected to or integrally formed with the second body 3411. The second body 3411 is located between the bearing plate 23 and the clutch 33. The second body 3411 is movably engaged with the shaft 321 of the driving force receiving member 32. The positioning part 3413 is configured to protrude from the second body 3411, specifically as a protrusion extending toward the driving force receiving part 3222. The positioning part 3413 is used to cooperate with the second positioning part 234 of the bearing plate 23 to restrict the pressure member 341 from rotating in the rotation direction of the driving force receiving member 32. That is, the pressure member 341 and the clutch 33 can rotate relative to each other.

[0097] The control element 342 interacts with the device-side action block 91. The control element 342 includes an action part 3423. During the installation of the processing box C into the device, the action part 3423 of the control element 342 is pressed by the device-side action block 91, thereby causing the pressing element 341 to push the clutch 33 in the longitudinal direction. Since the clutch 33 and the driving force receiving element 32 are engaged with each other, the clutch 33 and the driving force receiving element 32 move simultaneously in the longitudinal direction / rotation axis L1 of the driving force receiving element 32. In this embodiment, when the action part 3423 / control element 342 is pressed, the clutch 33 and the driving force receiving element 32 are driven to move to the left in the longitudinal direction / rotation axis L1 of the driving force receiving element 32. The clutch 33 moves from the transmission position to the disengagement position, thereby preventing the driving force receiving element 32 from interfering with the force output protrusion 922 of the driving force output element 92, so that the processing box C can be installed smoothly.

[0098] like Figure 10 As shown, the bearing plate 23 in this embodiment includes a plate body 231, a through hole 232, and a second positioning part 234. The through hole 232 and the second positioning part 234 penetrate the bearing plate 23 along the longitudinal direction / direction of the rotation axis L1 of the driving force receiver 32. The through hole 232 is used to movably engage with the shaft body 321 of the driving force receiver 32. The driving force receiver 32 extends outward from the through hole 232 and is radially positioned by the bearing plate 23. The actuating part... 3423 / Control element 342 passes through the second positioning portion 234 of the bearing plate 23 and is radially positioned by the bearing plate 23; in this embodiment, the bearing plate 23 is also provided with a first protrusion 235, which extends from the plate body 231 away from the end cover 13 in the longitudinal direction. When viewed from right to left in the longitudinal direction, the first protrusion 235 is in an arc shape surrounding a portion of the driving force receiving element 32. The first protrusion 235 is used to contact and position the processing box with the device-side action block 91. In this embodiment, as Figure 12A As shown, the action portion 3423 of the control member 342 is preferably disposed on the outer side of the first protrusion 235 (in the radial direction, on the side away from the driving force receiving member 32). In other words, the action portion 3423 is further away from the driving force receiving member 32 than the first protrusion 235, so as to make more stable contact with the device-side action block 91. Further, the outer side of the first protrusion 235 has a stepped surface 236 extending radially. In the longitudinal direction, the stepped surface 236 protrudes outward (away from the end cover 13) from the surface of the plate body 231 of the bearing plate 23. The stepped surface 236 is used to guide the processing box C to contact the device-side action block 91, thereby improving the installation and positioning accuracy of the processing box C. In the longitudinal direction, at least a portion of the action portion 3423 extends from the second positioning portion 234 and protrudes from the stepped surface 236.

[0099] Furthermore, the actuating part 3423 is provided with a first sliding surface 34231 and a second sliding surface 34232. Preferably, the intersection point 34233 of the first sliding surface 34231 and the second sliding surface 34232 is the vertex of the actuating part 3423. The first sliding surface 34231 and the second sliding surface 34232 are used to reduce the friction force of the actuating part 3423 being repeatedly rubbed by the device-side actuating block 91, so as to reduce component wear, extend component life, thereby reducing replacement frequency and reducing usage costs.

[0100] The reset member 343 is located between the clutch member 33 and the hub 31. The reset member 343 forces the clutch member 33 to move along the longitudinal direction / rotation axis L1 of the driving force receiving member 32, causing the clutch member 33 to return from the transmission position to the disengagement position, or vice versa. The direction of the reset force applied by the reset member 343 to the clutch member 33 is opposite to the direction of the force applied by the applied force to the clutch member 33. In this embodiment, the applied force forces the clutch member 33 to move from the transmission position to the disengagement position, and the reset member 343 forces the clutch member 33 back from the disengagement position to the transmission position. Therefore, the reset member 343 is configured as an elastic element that directly or indirectly contacts the clutch member 33. Preferably, in this embodiment, the reset member 343 is a compression spring.

[0101] When the processing box C enters the equipment along the installation direction, the control element 342 is not pressed by the equipment-side action block 91, the separation element 33 is in the transmission position, and the reset element 343 is in its natural state. The clutch element 33, the pressing element 341, and the driving force receiving element 32 are supported by the reset element 343. The driving force receiving part 3222 of the driving force receiving element 32 and the action part 3423 of the control element 342 extend outward. When pushed along the installation direction, the equipment-side action block 91 presses the action part 3423, and the action part 3423... 23 drives the pressing component 341, the clutch component 33, and the driving force receiving component 32 to move in the longitudinal direction, causing the driving force receiving part 3222 to retract toward the bearing plate 23. At this time, the driving force receiving part 3222 avoids the force output protrusion 922 to avoid interference. When the installation continues to be pushed along the installation direction, the equipment side action block 91 disengages from the action part 3423. At this time, the driving force receiving part 3222 re-extends under the action of the reset component 343 and completes engagement with the force output protrusion 922.

[0102] [Beneficial Effects]

[0103] (Examples 1 to 4)

[0104] 1. The driving force receiving component 32 involved in Embodiments 1 to 4 does not need to extend or retract along its rotation axis L1, nor does it need to be configured to be omnidirectional. The rotation axis L1 always remains parallel or collinear with the rotation axis of the rotating component. Before the driving force receiving component 32 and the driving force output component 92 are fully coupled, the rotation axis L1 and the driving force output component L2 are parallel to each other. After the driving force receiving component 32 and the driving force output component 92 are fully coupled, the rotation axis L1 and the rotation axis L2 are collinear. This not only reduces the manufacturing and assembly accuracy requirements of the driving force receiving component 32 / driving force receiving assembly 30, but also simplifies the structure of the driving force receiving component 32 / driving force receiving assembly 30.

[0105] 2. In Embodiment 1, the switching of the clutch 33 between the transmission position and the disengagement position and the rotation of the driving force receiving component by a certain angle can be simultaneously controlled by the control mechanism 34, thereby simplifying the structure of the driving force receiving component 30.

[0106] 3. During the installation and disassembly of the processing box C, the control mechanism 34 can control the clutch 33, causing the clutch 33 to change from the transmission position to the disengagement position. As a result, the driving force receiving component 32 can rotate freely to avoid or reduce interference with the driving force output component 92, so that the driving force receiving component 32 and the driving force output component 92 can be smoothly engaged or disengaged. Correspondingly, the processing box C can be smoothly installed or disassembled.

[0107] 4. The control component 342 is configured as a flexible component, so that the arrangement of the control component 342 in the processing box C is not limited by the structure of the processing box C. Thus, the control component 342 has a higher degree of installation freedom. Furthermore, the control component 342 also has better compatibility and can be used with a variety of processing boxes.

[0108] 5. When the control unit 342 is configured to include a first control unit 342a and a second control unit 342b, the control of the clutch 33 in the transmission position and the disengagement position, as well as the control of the rotation of the driving force receiving unit 32 at a certain angle, can be controlled separately. As a result, the service life of the first control body 3420a and the second control body 3420b can be extended, and the external force required by the first control body 3420a and the external force required by the second control body 3420b can be reduced.

[0109] 6. Based on Article 5, the user may operate only the first control unit 342a without operating the second control unit 342b. Only if the driving force receiver 32 and the driving force output unit 92 still interfere after operating the first control unit 342a should the second control unit 342b be operated. This not only helps to reduce the user's operation steps, but also prevents the simultaneous operation of the first control unit 342a and the second control unit 342b, or the operation of the first control unit 342a first and then the second control unit 342b, which would cause the driving force receiver 32 to interfere with the driving force output unit 92 again.
