Therefore, the combination of the rotating member and the driving force receiving member X4 can be collectively referred to as a rotating component.

[0090] When the processing box C is working, the photosensitive drum 21 contacts the developing roller 11, and the developing roller 11 supplies the developer to the photosensitive drum 21.

Before the processing box is installed on the device, the driving part 180h and the braking part 203a partially overlap.

[0102] The braking portion 203a includes a first braking engagement member 204 and a second braking engagement member 208. In the radial direction of the force output member 203, the first braking engagement member 204 is located outside the second braking engagement member 208, as described in the cited patent application Fig.43 As shown, the first brake engaging member 204 and the second brake engaging member 208 are coupled via the rotation stopping recess 204 c and the rotation stopping protrusion 208 c , so that the first brake engaging member 204 and the second brake engaging member 208 can rotate together around the axis M1 .

[0103] Further, the force output member 203 further includes a first spring (drum drive coupling spring) 210 and a second spring (brake combination spring) 211, the first spring 210 abuts against the brake transmission member 207, the flange portion 207a of the brake transmission member 207 abuts against the second brake combination member 208, and at the same time, the protrusion 207f of the brake transmission member 207 also abuts against the contact surface 180f of the driving force output member (as described in the cited patent application Fig.44 ) abuts; the second spring 211 abuts against the flange portion 204a of the first brake engaging member 204. Along the axis M1, the first brake engaging member 204, the second brake engaging member 208 and the driving portion 180h are configured to be able to retract and extend along the axis M1, that is, along the axis of the cited patent application Fig.48 The first brake structure 204 and the second brake combination member 208 can be retracted and extended along the axis M1 at the same time, and in some imaging devices, the two can also be retracted and extended along the axis M1 respectively; when the first brake combination member 204 moves along the axis M1 toward the direction indicated by M1A (the direction close to the flange portion 180a), the rotation stop recess 204c and the rotation stop protrusion 208c are disengaged, and the first brake combination member 204 can rotate freely around the axis M1; when the second brake combination member 208 moves along the axis M1 toward the direction indicated by M1A, through the rotation stop recess 204c and the rotation stop protrusion 208c, the first brake combination member 204 will also move along the axis M1 toward the direction indicated by M1A. Finally, the first brake combination member 204 and the second brake combination member 208 can both rotate freely around the axis M1.

[0104] Further, as mentioned in the cited patent application Fig.47 and this patent application Figure 2D As shown, the second brake engaging member 208 also has an inward protrusion 208e protruding radially inward from the coupling engaging portion 208b, along M1B (as shown in the cited patent application) in the opposite direction to M1A. Fig.48 In the direction shown in FIG. 2 , the inward protrusion 208e is located at the free end of the second brake engaging member 208. Figure 2A-2DAs shown, the driving force output surface 180d is located on the driving part 180h, and along the rotation direction of the force output member 203, the driving part 180h is opposite to the first brake coupling component 204. That is to say, a circle is drawn in a plane perpendicular to the rotation axis M1 with the point through which the rotation axis M1 passes as the center. The circle will pass through at least a part of the driving part 180h and at least a part of the first brake coupling component 204 at the same time.

[0105] Continue to refer Figures 2A-2D , the second brake combination member 208 has an inner protrusion 208e protruding toward the rotation axis M1, further, along the rotation direction r of the force output member 203, the first brake combination member 204 has an outer output surface 204g located downstream of the first brake combination member body 204z, the second brake combination member 208 has an inner output surface 208f located downstream of the second brake combination member body 208z, the inner protrusion 208e protrudes radially inward / toward the rotation axis M1 from the second brake combination member body 208z, and along the rotation direction r, the inner protrusion 208e has a plane 208g located downstream, and the plane 208g is adjacent to the inner output surface 208f; further, as Figure 2B As shown, along the rotation axis M1, the driving portion 180h has a driving end surface 180y located at the end, the first brake coupling member 204 has a first brake end surface 204y located at the end, and the second brake coupling member 208 has a second brake end surface 208y located at the end, and the end refers to the end of the driving portion 180h, the first brake coupling member 204 and the second brake coupling member 208 farthest from the flange portion 180a.

[0106] When the driving part 180h and the braking part 203a are close to each other, the driving part 180h and the braking part 203a are not in close contact with each other. Figure 2D As shown, along the rotation direction r, a gap is formed between the first braking end surface 204y and the driving portion 180h, and the minimum value of the gap is s, that is, the shortest distance between the first braking end surface 204y and the driving portion 180h is s.

[0107] like Figure 2C As shown, the driving parts 180h are arranged as two radially opposite to each other along the driving force output member 180, and the driving force output member 180 also includes a connecting member 180k connecting the two driving parts, and the connecting member 180k includes an intermediate member 183 and a first connecting member 181 and a second connecting member 182 respectively located on both sides of the radial direction of the intermediate plate 183, and the following positioning boss 180i protrudes from the intermediate plate 183 along the rotation axis M1, and the first connecting member 181 and the second connecting member 182 have the same structure and are respectively connected to one driving part.

[0108] Furthermore, a lower protrusion 180g is provided on a side surface (driving force output surface) 180d of the driving portion 180h facing the first brake coupling member 204, and along the rotation direction r, the driving portion 180h is also provided with an inclined surface 180j adjacent to the driving force output surface 180d, and an upper protrusion 204f is provided on a side surface of the first brake coupling member 204 facing the driving portion 180h. Before the processing box 100 is installed, the driving portion 180h and the first brake coupling member 204 approach each other along the rotation direction r, and along the rotation axis M1, the upper protrusion 204f and the lower protrusion 180g are relative / overlapping.

[0109] On the whole, the lower protrusion 180g is formed integrally with the first connecting member 181, and the driving force output surface 180d protrudes from the lower protrusion 180g along the rotation axis M1. Along the rotation direction r, the lower protrusion 180g can also be regarded as protruding from the first connecting member 181 / driving force output surface 180d, and the end of the lower protrusion 180g is formed as a front surface 180g1 that can rotate along the driving part 180h; further, along the rotation direction r, the first connecting member 181 also has a sub-front surface 180g2 located downstream in the rotation direction, the front surface 180g1 is connected to the sub-front surface 180g2, and the front surface 180g1 and the sub-front surface 180g2 are both located at the downstream end of the first connecting member 181, and therefore, the front surface 180g1 and the sub-front surface 180g2 can be collectively referred to as the downstream end surface of the first connecting member 181.

[0110] Along the rotation direction r, the force output member 203 has a first space K1, a second space K2 and a third space K3, wherein the first space K1 refers to the space between the front surface 180g1 and the braking portion 203a, and the second space K2 refers to the space between the braking portion 203a and the driving portion 180h located downstream of the braking portion. Specifically, Figure 2D As shown, the second space K2 refers to the space between the first braking force output portion 203a and the second driving force output portion 180m, or the space between the second braking force output portion 203b and the first driving force output portion 180h, and the third space K3 refers to the space between the driving portion 180h / driving force output surface 180d and the first braking combination member 204; when the driving portion 180h and the braking portion 203a partially overlap, as shown in FIG. Figure 2D As shown, along the rotation direction r, the second space K2 is larger than the first space K1 / the third space K3.

[0111] like Figure 4AAs shown, the driving force receiving member 4 involved in the utility model has a rotation axis L21, includes a connecting portion 41, a chassis 42, a base 43 and a coupling portion 44, along the rotation axis L21, the connecting portion 41, the chassis 42, the base 43 and the coupling portion 44 are arranged in sequence, the connecting portion 41 is directly or indirectly coupled to the rotating member, and is used to transmit the driving force to the rotating member to drive the rotating member to rotate, the chassis 42 abuts against the rotating member, so that the driving force receiving member 4 is positioned relative to the rotating member, the base 43 extends from the chassis 42, and the base 43 and the connecting portion 41 are respectively located on both sides of the chassis 42, and the coupling portion 44 extends from the base 43 in a direction away from the chassis 42; as a simplified structure, the chassis 42 can be omitted, and the base 43 extends directly from the connecting portion 41, and more simply, the base 43 can also be omitted, and the coupling portion 44 extends from the connecting portion 41.

[0112] The structure of the coupling portion 44 will be described below, and other structures of the driving force receiving member 4 are not limited here. In order to more clearly show the structure of the driving force receiving member involved in the utility model, only the driving force receiving member 4 is shown below, but it should be understood that the driving force receiving member 4 can be applied to various rotating members in the processing box. According to the actual needs of the product, those skilled in the art can also combine the following embodiments and their modified implementations with each other.

[0113]

Drive force receiving part

[0114] [Example 1]

[0115] Figure 4A It is a three-dimensional diagram of a photosensitive drum of a driving force receiving member involved in the first embodiment of the utility model; Figure 4B It is a three-dimensional diagram of the first driving force receiving member involved in the first embodiment of the utility model; Figure 4C It is a side view of the first driving force receiving member involved in the first embodiment of the utility model when observed along its rotation axis.

[0116] The photosensitive drum 21 has a rotation axis L21, and the driving force receiving member 4 includes a connecting portion 41 (eg, Figure 4B As shown), a chassis 42, a base 43 and a coupling portion 44, the coupling portion 42 realizes the connection between the driving force receiving member 4 and the photosensitive drum 21 by being embedded in the photosensitive drum 21, the chassis 42 abuts against the photosensitive drum 21, so that the driving force receiving member 4 is positioned relative to the photosensitive drum 21, the base 43 extends from the chassis 42, and the coupling portion 44 extends from the base 43 away from the chassis 42; as a simplified structure, the chassis 42 can be omitted, and the base 43 extends directly from the coupling portion 41, and more simply, the base 43 can also be omitted, and the coupling portion 44 extends from the coupling portion 41.

[0117] The structure of the coupling portion 44 will be described below, and other structures of the driving force receiving member 4 are not limited here.

[0118] The coupling portion 44 includes a central column 45 and a driving force receiving portion 46 extending radially outward from the central column 45, the rotation axis L21 passes through the central column 45, and two driving force receiving portions 46 are arranged radially opposite to each other on the periphery of the central column 45. Figure 4A and Figure 4B As shown, each driving force receiving portion 46 includes a base 461 connected to the center column 45 and a protrusion 462 located radially outside the base 461. Along the radial direction of the driving force receiving member 4, the protrusion 462 is located radially outside the base 461, and the guide surface 463 extends from the base 461 toward the protrusion 462. The protrusion 462 has a first surface / driving surface 464 and a second surface / braking surface 465 adjacent to the guide surface 463, and the first surface 464 and the second surface 465 are both parallel to the rotation axis L21.

[0119] As the process cartridge C is installed toward the device, the guide surface 463 guides the braking portion 203a to move relative to the driving portion 180h, so that the driving force receiving portion 46 reaches between the driving portion 180h and the braking portion 203a, that is, the driving force receiving portion 46 enters the third space K3. Figure 4C As shown, the driving force output surface 180d abuts against the first surface 464, and the second surface 465 is spaced apart from the braking portion 203a. When the driving portion 180h rotates along the rotation direction r, the driving force is transmitted to the coupling portion 44 through the first surface 464, and then the photosensitive drum 21 is driven to rotate around the rotation axis L21.

[0120] Since the second surface 465 and the braking portion 203a are spaced apart from each other, that is, the driving force receiving member 4 no longer needs to be braked when it stops working, and in the process of the processing box C returning from the working state to the non-working state or the process of the photosensitive drum 21 returning from the rotating state to the non-rotating state, along the circumferential direction of the photosensitive drum 21, the braking portion 203a does not apply the force / braking force to the driving force receiving member 4, which is equivalent to the braking portion 203a being shielded, which is beneficial to reducing the wear of the driving force receiving member 4 during operation. Furthermore, after adopting the driving force receiving member 4 involved in this embodiment, the braking portion 203a in the device no longer needs to return to a position close to or partially overlapping with the driving portion 180h, which is beneficial to simplify the structure of the device. For the driving portion 180h and the braking portion 203a that are already in a separated state, the driving force receiving member 4 of the next processing box does not need to be provided with a guide surface 463, and the structure of the processing box C can also be simplified.

[0121] [Example 2]

[0122] Figure 5A is a three-dimensional diagram of a driving force receiving member involved in the second embodiment of the present utility model; Figure 5B It is a side view of the driving force receiving member involved in the second embodiment of the present utility model when observed along its rotation axis.

[0123] For ease of understanding, the same structures as those of the first driving force receiving member 4 described above will be assigned the same reference numerals.

[0124] The structure of the driving force receiving portion 46 in this embodiment is different from that in the first embodiment. Figure 5A As shown, in this embodiment, the driving force receiving portion 46 is simplified to at least one independent protrusion 462, and the protrusion 462 also has a first surface 464 and a second surface 465 relative to each other. Along the rotation direction r, the first surface 464 is located upstream of the second surface 465. When the processing box C is installed to the predetermined position of the device, the first surface 464 reaches the downstream space K2 (second space K2) of the braking portion 203a. At this time, the first surface 464 is opposite to the braking portion 203a.

[0125] When the processing box C starts to work, the braking part 203a rotates together with the driving part 180h. At this time, the braking part 203a abuts against the first surface 464 and drives the driving force receiving member 4 to rotate along the rotation direction r. As in the first embodiment, the driving force receiving member 4 in this embodiment does not need to be braked by the braking part when it stops working, which is beneficial to reduce the wear of the driving force receiving member 4 during operation; in the process of the processing box C returning from the working state to the non-working state or the process of the photosensitive drum 21 returning from the rotating state to the non-rotating state, along the circumferential direction of the photosensitive drum 21, the driving part 180h does not apply a force / braking force to the driving force receiving member, which is equivalent to the driving part 180h being shielded.

[0126] The structure of the driving force receiving member 4 in this embodiment is simplified, and at the same time, the contact area between the driving force receiving part 46 and the force output member 203 is increased, thereby improving the combination stability of the driving force receiving part 46 and the force output member 203 and the force stability of the driving force receiving part 46, and the driving force receiving part 46 and the force output member 203 are not easy to separate.

[0127] On the other hand, since the second space K2 is the largest, the driving force receiving part 46 is more likely to enter the second space K2 than the driving force receiving part 46 entering the first space K1 or the third space K3. Therefore, the solution of using the braking part 203a to drive the driving force receiving member 4 can also improve the combination efficiency of the driving force receiving member 4 and the force output member 203, and prevent the driving force receiving member 4 from being misaligned with the force output member 203. [Example 3]

[0128] Figure 6 It is a three-dimensional diagram of the driving force receiving member involved in the third embodiment of the present utility model.

[0129] In the present embodiment, the braking surface 465 is cancelled. As shown in the figure, the driving force receiving portion 46 is only provided with a driving surface 464 and a guide surface 463. The guide surface 463 extends upward in a spiral from the base 43. After the processing box C having the driving force receiving portion 46 / driving force receiving member 4 is installed to the imaging device, the guide surface 463 can also be opposite to the coupling coupling part 204b / 208b of the braking portion 203a and play the same role as the braking surface 465. Therefore, the structure of the driving force receiving portion 46 is simplified, which is conducive to improving the production efficiency of the driving force receiving portion 46 and the driving force receiving member 4 having the driving force receiving portion 46.

[0130] Furthermore, the driving force receiving portion 46 further includes a flange portion 47, which is arranged along the outer circumference of the center column 45, or in other words, the flange portion 47 protrudes radially outward from the outer circumferential surface of the center column 45. Preferably, along the rotation axis L21, the flange portion 47 is located at the free end 451 of the center column 45 (the end away from the connecting portion 41). When viewed in a direction perpendicular to the rotation axis L21, the driving force receiving portion 46 and the flange portion 47 do not overlap. In the radial direction of the driving force receiving member 4, the protruding size of the flange portion 47 is The dimensions of the base 461 / driving surface 464 / guide surface 463 do not exceed those of the base 461 / driving surface 464 / guide surface 463. During the process of the driving force receiving member 4 with this structure being combined with the force output member 203, the coupling combining portion 204b / 208b of the braking portion 203a hooks the flange portion 47 to realize the combination of the driving force receiving member 4 and the force output member 203, which can effectively prevent the driving surface 464 of the driving force receiving member 4 from being disengaged from the driving force output surface 180d of the force output member 203, thereby ensuring that the driving force receiving member 4 can stably receive the driving force from the force output member.

[0131] [Example 4]

[0132] Figure 7 It is an exploded schematic diagram of the driving force receiving member involved in the fourth embodiment of the utility model; Fig. 8A It is a three-dimensional diagram of the driving force receiving member involved in the fourth embodiment of the present utility model beginning to be combined with the force output member; Figure 8B It is a three-dimensional diagram of the driving force receiving member and the force output member involved in the fourth embodiment of the utility model after being combined; Figure 8C It is a side view of the driving force receiving member and the force output member involved in the fourth embodiment of the present utility model after being combined, observed in a direction perpendicular to the rotation axis of the driving force receiving member.

[0133] In this embodiment, the coupling portion 44 is configured to be movable along the rotation axis L21 relative to the second rotating member / photosensitive drum 21 or the connecting portion 41, that is, the coupling portion 44 can move between a position close to the connecting portion 41 (a retracted state of the coupling portion) and a position away from the connecting portion 41 (an extended state of the coupling portion).

[0134] As shown in the figure, the coupling part 44 is formed separately from the base 43, and the driving force receiving member 4 also includes an active cavity 432 formed inside the base 43 and a retaining member 49 for maintaining the coupling part 44 at a position away from the second rotating member / photosensitive drum 21 or the connecting part 41, and the retaining member 49 is preferably configured as a compression spring; at this time, the driving force receiving member 4 can be decomposed into a coupled part 4z including the connecting part 41, the chassis 42 and the base 43, a coupling part 44 formed separately from the coupled part 4z, and a retaining member 49 located between the coupled part and the coupling part, the coupled part 4z is used to transmit the driving force received by the coupling part 44, and the retaining member 49 is used to push the coupling part 44 in a direction away from the coupled part 4z along the rotation axis L21. The coupling portion 44 includes a base plate 441, a center column 45 and a driving force receiving portion 46 extending from one side of the base plate 441, and a driving force transmitting portion 442 extending from the other side of the base plate 441. Along the rotation axis L21, the center column 45 and the driving force receiving portion 46 extend in a direction away from the connecting portion 41, and the driving force transmitting portion 442 extends in a direction close to the connecting portion 41.

[0135] The driving force receiving part 46 is still provided with a guide surface 463 and a driving surface 464, wherein, during the combination process of the driving force receiving member 4 and the force output member 203, the guide surface 463 is used to force the braking part 203a to rotate relative to the driving part 180h so that the braking part 203a and the driving part 180h are separated from each other, and the driving surface 464 is used to receive the driving force. The driving force receiving part 46 in this embodiment is not provided with a braking surface for receiving the braking force.

[0136] The driving force transmitting portion 442 is used to be combined with the base 43 to transmit the driving force received by the driving force receiving portion 46 to the base 43, thereby driving the rotating member 21 connected to the connecting portion 41 to rotate. In some embodiments, the driving force transmitting portion 442 is configured as a protrusion extending from the bottom plate 441 toward the direction close to the connecting portion 41 along the rotation axis L21, and accordingly, the side wall of the active cavity 432 is provided with a groove 433 that can cooperate with the protrusion, or the positions of the protrusion and the groove are interchanged; the chassis 42 is formed as the bottom wall of the active cavity 432, one end of the compression spring 49 abuts against the chassis 42, and the other end abuts against a side surface of the bottom plate 441 facing the connecting portion 41.

[0137] Furthermore, the coupling part 44 also includes a guide coupling column 443 arranged on the same side as the driving force transmission part 442. Correspondingly, a guide hole 421 cooperating with the guide coupling column 443 is arranged on the chassis 42. The guide coupling column 443 is arranged to be a cantilever that can elastically deform in a direction intersecting the rotation axis L21. A snap-in protrusion 444 is arranged at the end of the cantilever. During the installation process of the coupling part 44, the guide coupling column 443 is squeezed and elastically deformed, and the snap-in protrusion 444 is snap-fitted with the guide hole 421, so that the coupling part 44 and the connecting part 41 / base 43 can be stably coupled; during the movement of the coupling part 44 along the rotation axis L21, the cooperation between the guide coupling column 443 and the guide hole 421 can ensure that the movement trajectory of the coupling part 44 is not offset.

[0138] When the driving force receiving member 4 is combined with the force output member 203, the guide surface 463 forces the braking part 203a to rotate along the rotation direction r and separate from the driving part 180h. Subsequently, the driving surface 464 is opposite to the driving force output surface 180d, and the driving force receiving member 4 is combined with the force output member 203. The driving force receiving member 4 can receive the driving force output by the driving part 180h.

[0139] In this embodiment, the braking portion 203a will gradually retract towards a retracted state while being pushed and guided by the guide surface 463. When the driving surface 464 is opposite to the driving force output surface 180d, the braking portion 203a can be in a state of being compressed by the guide surface 463, or it can be in an extended state where it is no longer compressed by the guide surface 463. No matter what state the braking portion 203a is in, it will not affect the driving force output surface 180d from outputting the driving force to the driving surface 464. At this time, the braking portion 203a will not apply braking force to the driving force receiving component 4 and can be regarded as being shielded.

[0140] Different from the above-mentioned embodiment, the coupling part 44 in this embodiment is configured to be retractable. During the coupling process between the driving force receiving member 4 and the force output member 203, the braking part 203a is pressed by the guide surface 463. Conversely, the guide surface 463 is also pressed by the braking part 203a. The coupling part 44 will retract in the direction close to the connecting part 41 / photosensitive drum 21, and the compression spring 49 will also undergo elastic deformation. In this way, the driving force receiving part 46 will be pushed toward the force output member 203 by the compression spring 49. In other words, the driving force receiving part 46 can follow the movement of the driving part 180h / braking part 203a. Finally, the driving force receiving part 4 and the force output member 203 can also maintain a stable and tight coupling.

[0143] The above describes an embodiment of applying driving force to the driving force receiving member 4 by utilizing the driving force output surface 180d provided in the driving portion 180h. However, during the operation of the force output member 203, the braking portion 203a will also rotate following the driving portion 180h. Therefore, the braking portion 203a can also be used as a component for applying driving force to the driving force receiving member 4. The following describes an embodiment of combining the braking portion 203a with the driving force receiving member 4 to transmit driving force.

[0144] like Fig. 9 As shown, the driving force receiving portion 46 still includes a base 461 and a protrusion 462 located radially outside the center column 45, wherein the protrusion 462 is farther away from the rotation axis L21 than the base 461, and the protrusion 462 is provided with a driving surface 464 for receiving the driving force, and the driving surface 464 can be combined with the first brake combining component 204, and can also be combined with the second brake combining component 208. This embodiment will describe the combination of the driving surface 464 and the second brake combining component 208.

[0145] As described above, along the radial direction of the force output member 203 , the second brake engagement member 208 is located inside the first brake engagement member 204 . Preferably, along the rotation direction r, the driving surface 464 is opposite to the second brake engagement member 208 .

[0146] As shown in the figure, along the rotation direction r, the second brake engagement component 208 has an inner output surface 208f located downstream. Relative to the rotation axis L21, the inner output surface 208f is arranged to rise in a spiral in the direction opposite to the rotation direction r. Preferably, the driving surface 464 is arranged to be a spiral surface matching the inner output surface 208f.

[0147] like Fig. 10A , Fig. 10B , Fig.11A and Fig. 11B As shown, in order to more clearly show the combination state of the second brake combination member 208 and the driving force receiving member 2, Fig. 11B The driving portion 180h and the first brake engaging member 204 are hidden in FIG.

[0148] Before the driving force receiving member 4 is combined with the force output member 203, the driving part 180h and the braking part 203a are separated from each other along the rotation direction r. During the process of the driving force receiving member 4 and the force output member 203 being combined, if the braking part 203a abuts against the protrusion 462, the braking part 203a will be compressed and retracted. As the force output member 203 rotates, when the driving part 180h abuts against the braking part 203a, the driving part 180h and the braking part 203a rotate together along the direction indicated by r until the protrusion 462 no longer abuts against the braking part 203a and the driving part 180h, and the braking part 203a and the driving part 180h extend out, as shown in FIG. Fig. 11B As shown, the inner output surface 208 f abuts against the driving surface 464 , the second brake engaging member 208 starts to output the driving force to the driving force receiving member 4 , and the braking portion 203 a will no longer apply a braking force to the driving force receiving member 4 .

[0149] like Fig.12 As shown, before the driving force receiving member 4 is combined with the force output member 203, the driving portion 180h and the braking portion 203a are close to each other along the rotation direction r. As the process cartridge C is installed, the protrusion 462 presses the driving portion 180h and / or the braking portion 203a, and the driving portion 180h and / or the braking portion 203a retracts. As the driving portion 180h rotates, the driving portion 180h will push the braking portion 203a to rotate together. When the driving portion 180h and / or the braking portion 203a When a is no longer squeezed by the protrusion 462, the first spring / drum drive coupling spring 210 and / or the second spring / brake combining spring 211 arranged in the force output member 203 release the elastic force to make the driving part 180h and / or the braking part 203a extend out, and then the inner output surface 208f abuts against the driving surface 464, the second brake combining component 208 starts to output the driving force to the driving force receiving member 4, and the braking part 203a will no longer apply braking force to the driving force receiving member 4.

[0150] Furthermore, the base 461 is also provided with a retaining surface 4611. Along the rotation axis L21, the retaining surface 4611 faces the connecting portion 41. Along the radial direction perpendicular to the rotation axis L21, the retaining surface 4611 is closer to the rotation axis L21 than the driving surface 464. When the inner output surface 208f abuts against the driving surface 464, the inner protrusion 208e of the second braking engagement member abuts against the retaining surface 4611, and the braking portion 203a can be maintained in a state of stable and tight combination with the driving force receiving member 4. Therefore, the retaining surface 4611 can be regarded as an embodiment of the anti-slip portion 47.

[0151] Furthermore, the base 461 further includes a guide surface 463 disposed adjacent to the retaining surface 4611. Fig. 10A and Fig. 10B As shown, during the combination of the driving force receiving member 4 and the force output member 203, the guide surface 463 abuts against the braking portion 203a to guide the inner protrusion 208e to a position combined with the retaining surface 4611 and to lead the outer output surface 204g / inner output surface 208f to a position opposite to the driving surface 464.

[0152] [Example 6]

[0153] Fig.13 is a three-dimensional diagram of a driving force receiving member involved in Embodiment 6 of the present utility model; Fig.14A is a three-dimensional diagram of the driving force receiving member and the driving part involved in the sixth embodiment of the utility model after being combined; Fig. 14B It is a side view of the driving force receiving member involved in the sixth embodiment of the present utility model after being combined with the driving part, when viewed along a direction perpendicular to the rotation axis of the driving force receiving member.

[0154] Different from the fifth embodiment, the driving force receiving member 4 in this embodiment is driven by the first brake coupling member 204, and along the rotation direction r, the first brake coupling member 204 has an outer output surface 204g located downstream, and the outer output surface 204g is also arranged to extend spirally upward in the direction opposite to the rotation direction r.

[0155] like Fig.13 As shown, the driving force receiving portion 46 in this embodiment includes a base 461 and a protrusion 462 located radially outside the center column 45, and the protrusion 462 is farther away from the rotation axis L21 than the base 461. A driving surface 464 that can cooperate with the outer output surface 204g is arranged on the protrusion 462, and an avoidance portion 468 is also formed between the driving surface 464 and the center column 45 along the radial direction perpendicular to the rotation axis L21. Specifically, the avoidance portion 468 is formed on the protrusion 462.

[0156] like Fig.14AAs shown in the figure, in order to more clearly show the function of the avoidance portion 468, the first brake combination member 204 is hidden in the figure. The combination process of the combination portion 44 / driving force receiving member 4 and the force output member 203 in this embodiment is the same as that in the fifth embodiment, and will not be repeated here. However, when the driving force receiving member 4 and the force output member 203 are completely combined, at least a part of the second brake combination member 208 enters the avoidance portion 468, as shown in FIG. Fig. 14B As shown, the outer output surface 204 g abuts against the driving surface 464 , the first brake engaging member 204 starts to output the driving force to the driving force receiving member 4 , and the braking portion 203 a will no longer apply a braking force to the driving force receiving member 4 .

[0157] Preferably, the base 461 in this embodiment may also be provided with the above-mentioned retaining surface 4611 or a rough surface or a surface with attached elastic rubber. While the outer output surface 204g abuts against the driving surface 464, the inner protrusion 208e of the second braking coupling component 208 entering the avoidance portion 468 is also combined with the retaining surface 4611 / rough surface / surface with attached elastic rubber. Therefore, the braking portion 203a can be maintained in a state of stable and tight combination with the driving force receiving member 4.

[0158] Optionally, when the retaining surface 4611 is not provided in the coupling portion 44, the base 461 forming the retaining surface 4611 may be omitted, but along the radial direction of the driving force receiving member 4, the bottom plate 441 located between the center column 45 and the protrusion 462 may be regarded as the base 461, and the structure of the coupling portion 44 may be simplified.

[0159] As described above, the retaining surface 4611 can be used to prevent the driving force receiving member 4 from being detached from the force output member 203. Therefore, the retaining surface 4611 is either set as a rough surface or set as a surface with elastic rubber attached, which can also be regarded as an embodiment of the anti-detachment part 47. In various embodiments of the anti-detachment part 47, technicians in this field can make a selection according to design requirements to ensure that the driving force receiving member 4 and the force output member 203 are stably and tightly combined.

[0160] [Example 7]

[0161] Fig.15 is a three-dimensional diagram of a driving force receiving member involved in Embodiment 7 of the present utility model; Fig.16 It is a schematic diagram of a state where the coupling portion of the driving force receiving member involved in the seventh embodiment of the present utility model is separated from the base; Fig.17 is a side view when viewed in a direction perpendicular to the rotation axis of the driving force receiving member involved in the seventh embodiment of the present utility model; Fig.18 It is a side view of the driving force receiving member and the force output member involved in the seventh embodiment of the present utility model after being combined, when viewed along a direction perpendicular to the rotation axis of the driving force receiving member.

[0162] Similar to the fourth embodiment, in this embodiment, the combining portion 44 and the combined portion 4z are also formed separately, so that the combining portion 44 and the combined portion 4z can be made of different materials. For example, the combining portion 44 is made of metal, and the combined portion 4z is made of resin material. The combining portion 44 used for combining with and disengaging from the force output member 203 will become more wear-resistant and have higher hardness. In some embodiments, the combining portion 44 and the combined portion 4z can also be made of the same material.

[0163] like Fig.16 As shown, the coupling portion 44 has a bottom plate 441 and a driving force transmitting portion 442 extending from one side of the bottom plate 441, and correspondingly, the coupled portion 4z is provided with an active cavity 432 which can be coupled with the driving force transmitting portion 442, and the center column 45 and the driving force receiving portion 46 are both extended from the other side of the bottom plate 441, that is, the driving force receiving portion 46 is connected to the center column 45 through the bottom plate 441, and therefore, at least a portion of the bottom plate 441 can also be regarded as a base 461.

[0164] The driving force receiving portion 46 includes a base 461 and a protrusion 462 located radially outside the center column 45, and the protrusion 462 is farther away from the rotation axis L21 than the base 461. The driving force receiving portion 46 is configured to be combined with the braking portion 203a. When the force output member 203 rotates along the rotation direction r, at least one of the outer output surface 204g and the inner output surface 208f in the braking portion 203a outputs driving force to the driving force receiving portion 46.

[0165] Similar to the sixth embodiment, an escape portion 468 is further formed between the driving surface 464 and the center column 45 along the radial direction perpendicular to the rotation axis L21. Specifically, the escape portion 468 is provided on the protrusion 462. When the driving force receiving member 4 is combined with the force output member 203, the second braking combination member 208 enters the escape portion 468, and the first braking combination member 204 is opposite to the driving surface 464. Therefore, there are the following three ways for the force output member 203 to output the driving force to the driving force receiving member 4:

[0166] In the first case, the outer output surface 204g of the first brake coupling member 204 is coupled to the driving surface 464, the second brake coupling member 208 does not contact the surface in the avoidance portion 468, and the driving force of the force output member 203 is transmitted from the first brake coupling member 204 to the driving force receiving member 4;

[0167] The second type is that the outer output surface 204g of the first brake combination member 204 is not combined with the driving surface 464, and the second brake combination member 208 is in contact with the surface in the avoidance portion 468, and the driving force of the force output member 203 is transmitted to the driving force receiving member 4 by the second brake combination member 208. At this time, the surface of the driving force receiving portion 46 for receiving the driving force will be the surface in the avoidance portion 468;

[0168] The third type is that the outer output surface 204g of the first brake coupling component 204 is coupled to the driving surface 464, and the second brake coupling component 208 is also in contact with the surface in the avoidance portion 468. The driving force of the force output component 203 is transmitted to the driving force receiving component 4 by the first brake coupling component 204 and the second brake coupling component 208 at the same time. At this time, the driving surface 464 and the surfaces in the avoidance portion 468 are both surfaces for receiving the driving force.

[0169] Furthermore, the driving force receiving portion 46 also includes a protrusion 469 arranged on the surface for receiving the driving force. When the driving force receiving member 4 is combined with the force output member 203, the protrusion 469 is combined with the braking portion 203a. In the process of the braking portion 203a outputting the driving force to the driving force receiving member 4, the braking portion 203a will be subjected to the reaction force from the driving force receiving member 4 and has a tendency to disengage from the driving force receiving member 4. The setting of the above-mentioned protrusion 469 can increase the friction between the braking portion 203a and the driving force receiving member 4, thereby preventing the driving force receiving member 4 from disengaging from the braking portion 203a. Therefore, the protrusion 469 can also be regarded as an embodiment of the above-mentioned anti-detachment portion 47.

[0170] The surface for receiving the driving force (taking the driving surface 464 as an example) has a shape matching the outer output surface 204g and / or the inner output surface 208f, and a plurality of protrusions 469 are provided on the surface for receiving the driving force, such as Fig.17 and Fig.18 As shown, the surface for receiving the driving force is set as a spiral surface extending around the rotation axis L21. When viewed in a direction perpendicular to the rotation axis L21, the protrusion 469 is tilted toward one side of the photosensitive drum 21 / connecting portion 41 as a whole, and has a surface 4691 facing the photosensitive drum 21 / connecting portion 41, thereby increasing the friction between the force output member 203 and the driving force receiving member 4; alternatively, the plurality of protrusions 469 can also be replaced by a rough surface, elastic rubber, etc.

[0171] When the engaging portion 44 and the engaged portion 4z do not need to be made of different materials, the engaging portion 44 and the engaged portion 4z may also be formed integrally, and thus, the manufacturing of the driving force receiving member 4 becomes easier.

[0172] [Embodiment 8]

[0173] Fig.19 It is a stereoscopic diagram of the driving force receiving member involved in the eighth embodiment of the present utility model.

[0174] Based on the seventh embodiment, the present embodiment further simplifies the structure of the protrusion 462. As shown in the figure, an avoidance portion 468 is also formed between the driving surface 464 and the center column 45 along the radial direction perpendicular to the rotation axis L21. However, the avoidance portion 468 is no longer formed on the protrusion 462, but is located between the protrusion 462 and the center column 45. That is to say, along the radial direction perpendicular to the rotation axis L21, the space between the protrusion 462 and the center column 45 is the avoidance portion 468.

[0175] When the driving force receiving member 4 is combined with the force output member 203, the second braking combination component 208 enters the avoidance portion 468, and the driving surface 464 arranged on the protrusion 462 is opposite to the outer output surface 204g, and the driving force output by the force output member 203 is transmitted to the driving surface 464 from the outer output surface 204g.

[0176] Alternatively, the driving force receiving member 4 can be configured such that when the driving force receiving member 4 is combined with the force output member 203 , the driving surface 464 is opposite to the inner output surface 208 f , and the driving force output by the force output member 203 is transmitted to the driving surface 464 from the inner output surface 208 f .

[0177] [Example 9]

[0178] Fig. 20 is a three-dimensional diagram of a driving force receiving member involved in Embodiment 9 of the present utility model; Fig.21 It is a three-dimensional diagram of the driving force receiving member and the force output member involved in the ninth embodiment of the present utility model after being combined.

[0179] According to the structure of the force output member 203 , the driving force receiving member 4 in this embodiment is configured to engage with the plane 208 g of the second brake engaging member 208 when the driving force receiving member 4 is engaged with the force output member 203 .

[0180] The driving force receiving portion 46 includes a guide surface 463 disposed on the protrusion 462 and a driving surface 464 disposed adjacent to the guide surface 463, wherein the driving surface 464 is a surface matching the plane 208g. Fig. 20 As shown, the drive surface 464 is parallel to the rotation axis L21.

[0181] Preferably, the guide surface 463 is configured as a helical surface extending around the rotation axis L21, such as Fig.21 As shown, during the process of combining the driving force receiving member 4 with the force output member 203, the guide surface 463 is guided by the outer output surface 204g or the inner output surface 208f, so that the driving force receiving part 46 can smoothly reach the position where the plane 208g is relative to the driving surface 464. As the force output member 203 rotates, the driving force is transmitted from the plane 208g to the driving surface 464.

[0182] [Example 10]

[0183] Fig.22A is a three-dimensional diagram of a driving force receiving member involved in Embodiment 10 of the present utility model; Fig. 22B is a side view when viewed along the rotation axis of the driving force receiving member involved in the tenth embodiment of the present utility model; Fig.23 It is a three-dimensional diagram of the driving force receiving member and the force output member involved in the tenth embodiment of the utility model after being combined; Fig.24 The driving force receiving member and the force output member of the tenth embodiment of the present utility model are combined, along Fig.23 Section view taken along the AA direction.

[0184] According to the structure of the force output member 203 , the driving force receiving member 4 in this embodiment is arranged so that when the driving force receiving member 4 is combined with the force output member 203 , the driving force receiving member 4 is combined with the front surface 180g1 of the driving portion 180h.

[0185] like Fig.22A and Fig. 22B As shown, the driving force receiving portion 46 includes a base 461 and a protrusion 462 located radially outside the center column 45, wherein the protrusion 462 is farther away from the rotation axis L21 than the base 461, and the protrusion 462 forms a strip body extending along the rotation axis L21, and is still provided with a guide surface 463 and a driving surface 464, wherein the guide surface 463 is arranged as an inclined surface or a spiral surface inclined relative to the rotation axis L21, and the driving surface 464 is arranged adjacent to the guide surface 463, and the driving surface 464 can match the front surface 180g1.

[0186] like Fig.23 As shown, when the driving force receiving member 4 is combined with the force output member 203, the guide surface 463 enters between the driving portion 180h / driving force output surface 180d and the braking portion 203a under the guidance of the inclined surface 180j, and the driving surface 464 is opposite to the front surface 180g1. As the force output member 203 rotates, the driving force is transmitted to the driving surface 464 through the front surface 180g1. Preferably, the front surface 180g1 and the driving surface 464 are both arranged to be parallel to the rotation axis L21 / M1.

[0187] Furthermore, the driving force receiving portion 46 also includes a reinforcing portion 46e, and along the rotation direction r, the protrusion 462 is spaced apart from the reinforcing portion 46e, wherein the protrusion 462 is used to receive the driving force and can be called the driven portion 46d, and the reinforcing portion 46e is used to enhance the strength of the driving force receiving member 4 to prevent the driving force receiving member 4 from being broken during the process of receiving the driving force, and can also prevent the driving force receiving member 4 from being rolled over and broken by an unexpected collision before combining with the force output member 203.

[0188] like Fig.24As shown, when the driving force receiving member 4 is combined with the force output member 203, the front surface 180g1 of the first connecting member 181 abuts against the driven part 46d, and the reinforcing part 46e abuts against the second connecting member 182, which not only ensures the stable combination of the driven part 46d and the front surface 180g1, but also plays a role in positioning the driven part 46d.

[0189] In a variation of this embodiment, continue as Fig.24 As shown, the driving surface 464 can also be configured to receive the driving force by abutting against the sub-front surface 180g2. Along the rotation direction r, the sub-front surface 180g2 is relative to and separated from the first brake engaging member 208. When the driving surface 464 abuts against the sub-front surface 180g2, the protrusion 462 will not contact the first brake engaging member 208. It can be seen that in this deformation mode, the driving part 180h does not need to be separated from the braking part 203a, and the driving force can be output from the driving part 180h to the protrusion 462.

[0190] [Example 11]

[0191] Fig.25A It is an exploded schematic diagram of the driving force receiving member involved in the eleventh embodiment of the utility model; Fig.25B It is an exploded schematic diagram of a modified embodiment of the eleventh embodiment of the utility model after the driving force receiving member is separated from the second unit housing; Fig.25C is along Fig.25B Sectional view after cutting in the middle DD direction; Fig.26A is a three-dimensional diagram of a driving force receiving member involved in the eleventh embodiment of the present utility model; Fig.26B is a side view of the driving force receiving member according to the eleventh embodiment of the present utility model when viewed along the rotation axis; Fig.27A and Fig.27B This is a state diagram of the driving force receiving member and the force output member involved in the eleventh embodiment of the utility model after being combined.

[0192] Similar to the tenth embodiment, the driving force receiving member 4 in this embodiment is configured such that when the driving force receiving member 4 is combined with the force output member 203, the driving force receiving member 4 is combined with the front surface 180g1 of the driving portion 180h.

[0193] If the driving force receiving member 4 and the force output member 203 adopt the combination method of using the braking part 203a to output the driving force to the driving force receiving member 4 as described in the above embodiment, in actual testing, the imaging device will produce unacceptable noise. According to preliminary analysis, the noise is caused by the collision between the driving part 180h and the braking part 203a that are close to each other, or by the contact between the parts of the force output member 203 and the inner wall of the imaging device, or by the retraction of the braking part 203a toward the inside of the cylindrical part 180c.

[0194] To this end, this embodiment provides a driving force receiving member 4 that can eliminate the above-mentioned noise. Fig.25A As shown, the driving force receiving member 4 includes a connecting portion 41, a chassis 42, a main body 4x and an auxiliary member 4y, wherein the main body 4x is connected to the connecting portion 41 or the chassis 42, the auxiliary member 4y is arranged to be rotatable relative to the main body 4x / processing box shell / photosensitive drum 21, and at least a part of the auxiliary member 4y and the connecting portion 41 are respectively located on both sides of the chassis 42; specifically, the main body 4x includes a base 43 connected to the connecting portion 41 or the chassis 42 and a connecting portion 44 arranged on the base 43, and the connecting portion 44 includes a central column 45 and a central column 45 along the central column 45. The driving force receiving portion 46 extends radially outward, and the rotation axis L21 passes through the center column 45. The driving force receiving portion 46 includes a base 461 and a protrusion 462. Along the radial direction of the driving force receiving member 4 / combination portion 44, the protrusion 462 is located radially outside the base 461; as described above, the coupling portion 44 also includes a bottom plate 441, and the center column 45 extends from one side of the bottom plate 441 along the rotation axis L21. The coupling portion 44 is connected to the base 43 via the bottom plate 441. In this embodiment, at least a portion of the bottom plate 441 can be regarded as the base 461.

[0195] The protrusion 462 is configured as a columnar body extending along the rotation axis L21, and a driving surface 464 for receiving a driving force is configured on the protrusion 462. Preferably, the main body 4x is formed integrally with the connection portion 41 and the chassis 42, and the base 43 and the coupling portion 44 are also formed integrally. The protrusion 462 also has a fourth surface 4621. Along the rotation axis L21, the fourth surface 4621 is the surface of the protrusion 462 that is farthest from the connection portion 41. Along the rotation axis L21, when the protrusion 462 extends beyond the central column 45, the fourth surface 4621 is the end surface 4w of the driving force receiving member 4. Preferably, the fourth surface 4621 is a plane, and more preferably, the fourth surface 4621 is a plane perpendicular to the rotation axis L21.

[0196] The auxiliary part 4y includes a carrier body 4y1, a separating part 4y2 protruding from the carrier body 4y1, and a limited portion 4y4 arranged on the carrier body 4y1 or the separating part 4y2. In some embodiments, the auxiliary part 4y / carrier body 4y1 is sleeved on the outside of the main body 4x, and the main body 4x is also provided with a limiting portion 434 for combining with the limited portion 4y4. Through the combination of the limited portion 4y4 and the limiting portion 434, the auxiliary part 4y is restricted along the direction of the rotation axis L21, and the auxiliary part 4y is not restricted along the rotation direction r. In some embodiments, the carrier 4y1 is configured as a ring body with an accommodating cavity 4y6 formed inside, at least a portion of the main body 4x is accommodated in the accommodating cavity 4y6, and the limiting portion 4y4 is configured as a snap-fit ​​protrusion that protrudes radially from the ring body 4y1 toward the accommodating cavity 4y6, and the limiting portion 434 is a snap-fit ​​groove arranged on the outer surface of the base 43 or the combining portion 44, and the snap-fit ​​groove 434 extends along the rotation direction r; conversely, the snap-fit ​​groove can also be arranged on the ring body 4y1, and the snap-fit ​​protrusion 4y4 can also be arranged on the base 43 or the combining portion 44, and the snap-fit ​​protrusion can extend a full circle along the rotation direction r, or only extend a predetermined angle along the rotation direction r.

[0197] In some embodiments, in order to facilitate the combination of the snap-fit ​​protrusion 4y4 and the snap-fit ​​groove 434, the auxiliary component 4y is further provided with an elastic arm 4y3 connected to the ring body 4y1, and the snap-fit ​​protrusion 4y4 / the snap-fit ​​groove 434 is provided on the elastic arm 4y3, and the elastic arm 4y3 can be elastically deformed relative to the ring body 4y1, so as to realize the convenient combination of the auxiliary component 4y and the main body 4x; preferably, the elastic arm 4y3 and the main body 4y1 are formed integrally, and a gap is formed between the elastic arm 4y3 and the main body 4y1 so that the elastic arm 4y3 can be elastically deformed relative to the main body 4y1; more preferably, in the case of providing the elastic arm 4y3, the snap-fit ​​portion 4y4 / the snap-fit ​​portion 434 is only provided on the elastic arm 4y3, which is more conducive to the convenient combination of the auxiliary component 4y and the main body 4x.

[0198] In some embodiments, the auxiliary component 4y can also be sleeved on the shell of the processing box, and the limited portion 4y4 can also be set on the auxiliary component 4y, and a limiting portion for limiting the limited portion 4y4 can be set on the shell. It is sufficient to ensure that the auxiliary component 4y can rotate in a direction parallel to the rotation axis L21 and that the auxiliary component 4y will not be separated from the shell; for example, the auxiliary component 4y can be restricted by abutting the end faces of the shell and the auxiliary component 4y; based on the inventive concept of the utility model, the auxiliary component 4y has multiple installation positions. For example, the auxiliary component 4y is sleeved on at least one of the charging component, the supply component and the stirring component.

[0199] Specifically, Fig.25B and Fig.25CAs shown, the main body 4y1 is still provided with an elastic arm 4y3, and the elastic arm 4y3 has a snap-fitting portion 4y4. The housing / second unit housing 2 includes a support member 25 and a limiting portion 434 provided in the support member 25. As shown in the figure, the auxiliary member 4y is rotatably supported by the support member 25. Along the rotation axis L21, the snap-fitting portion 4y4 abuts against the limiting portion 434, so that the auxiliary member 4y is limited in the direction of the rotation axis L21, but is not limited in the rotation direction r. Further, the auxiliary member 4y is sleeved on the outside of the main body 4x, or in other words, the main body 4x enters the accommodating cavity 4y6, and the auxiliary member 4y can rotate around the main body 4x.

[0200] In some embodiments, the auxiliary component 4y can also be installed in a rotatable manner in a preset positioning groove of the shell or the main body 4x. In this structure, there is no need to set up a component to support the auxiliary component 4y in the positioning groove. The inner wall of the positioning groove can be used to position the auxiliary component 4y. Therefore, the carrier 4y1 can also be set as a solid body, as long as the carrier 4y1 can rotate relative to the shell / photosensitive drum 21.

[0201] Preferably, when the auxiliary member 4y is coaxially arranged with the main body 4x, the separator 4y2 and the protrusion 462 are spaced apart from each other along the radial direction of the driving force receiving member 4, so that the auxiliary member 4y provided with the separator 4y2 can rotate freely around the rotation axis L21.

[0202] Furthermore, the separation member 4y2 is provided with a guide surface 463 and a hook surface 46f, and along the rotation axis L21, the separation member 4y2 has a tip portion 4y22 farthest from the connecting portion 41, wherein the guide surface 463 is used to guide the separation member 4y2 to a predetermined position, the hook surface 46f is arranged to be inclined relative to the rotation axis L21, and the inclination direction of the hook surface 465 is such that when viewed in a direction perpendicular to the rotation axis L21, the hook surface 46f faces the connecting portion 41, and thus, the hook surface 46f can prevent the braking portion 203a from moving toward the flange portion 180a, that is, the hook surface 46f can prevent the force output member 203 from separating from the driving force receiving member 4.

[0203] During the movement of the driving force receiving member 4 toward the force output member 203, the guide surface 463 abuts against the braking portion 203a and forces the braking portion 203a to move away from the driving portion 180h along the rotation direction r. Subsequently, along the rotation direction r, the separating member 4y2 enters the third space K3 between the driving portion 180h and the braking portion 203a, and the separating member 4y2 is opposite to the driving force output surface 180d. At the same time, the protrusion 462 reaches downstream of the front surface 180g1 and is located in the first space K1, and the front surface 180g1 is opposite to the driving surface 464.

[0204] When the force output member 203 starts to rotate, the driving force output by the driving portion 180h is transmitted to the driving force receiving member 4 through the abutment between the front surface 180g1 and the driving surface 464, and the hook surface 46f is combined with the braking portion 203a. Since the hook surface 46f is set to be an inclined surface as described above, the braking portion 203a is "hooked" by the hook surface 46f and will not move along the rotation axis L21 toward the flange portion 180a. The hook surface 46f can also be regarded as an embodiment of the anti-slip portion.

[0205] The driving part 180 and the braking part 203a are separated by the separating member 4y2, or in other words, at least a part of the separating member 4y2 enters the third space K3. When the driving force receiving member 4 described in this embodiment receives the driving force output by the force output member 203, the noise emitted by the imaging device is eliminated. Accordingly, as long as the separating member 4y2 can enter the third space K3, so that the driving part 180h and the braking part 203a are separated from each other along the rotation direction r, the barb surface 46f does not need to be set.

[0206] As described above, the separator 4y2 in this embodiment is configured to become movable as the carrier 4y1 rotates relative to the housing / photosensitive drum 21. Therefore, during the installation and removal of the processing box C, the movable carrier 4y1 / separator 4y2 improves the installation flexibility and removal flexibility of the processing box C, and reduces the risk of interference between the processing box C and the imaging device.

[0207] [Example 12]

[0208] Fig.28 is a three-dimensional diagram of a driving force receiving member involved in Embodiment 12 of the present utility model; Fig.29 This is a state diagram of the driving force receiving member and the force output member involved in the twelfth embodiment of the utility model after being combined.

[0209] The difference between this embodiment and the eleventh embodiment is that the driving force receiving member 4 in this embodiment does not abut against the front surface 180g1 to receive the driving force, but abuts against at least one of the outer output surface 204g and the inner output surface 208f of the braking portion 203a to receive the driving force.

[0210] The projection 462 is provided with a driving surface 464 which can match at least one of the outer output surface 204g and the inner output surface 208f. The outer output surface 204g and the inner output surface 208f both extend spirally relative to the rotation axis L21, and the extending direction is opposite to the rotation direction r. Fig.29As shown, when the driving surface 464 is combined with the inner output surface 208f, as the force output member 203 rotates along the rotation direction r, the driving surface 464 receives the driving force from the first brake coupling component 208, but the protrusion 462 also applies a reaction force toward the flange portion 180a to the first brake coupling component 208. This reaction force makes the second brake coupling component 208 tend to move toward the flange portion 180a. Therefore, there is a risk of the driving surface 464 and the inner output surface 208f being separated from each other.

[0211] However, when the barbed surface 46f provided in the separation member 4y2 is combined with the braking portion 203a, the braking portion 203a has a tendency to be pulled in a direction away from the flange portion 180a or in a direction close to the connecting portion 41, and the tendency of the braking portion 203a to move toward the flange portion 180a is stopped, so that the driving surface 464 and the inner output surface 208f can be stably combined.

[0212] As described above, the driving surface 464 in this embodiment is combined with the inner output surface 208f, however, in some embodiments, the driving surface 464 can also be configured to be combined with the outer output surface 204g. For example, the auxiliary part 4y can be rotatably installed in the receiving groove provided on the base 43. Along the radial direction of the driving force receiving part 4, the receiving groove is located on the radial inner side of the protrusion 462. In the process of the driving force receiving part 4 being combined with the force output part 203, the separating part 4y2 enters between the driving part 180h and the braking part 203a and separates the driving part 180h and the braking part 203a from each other along the rotation direction r, and the protrusion 462 reaches the second space K2.

[0213] [Example 13]

[0214] Fig.30 is a three-dimensional diagram of a driving force receiving member involved in Embodiment 13 of the present utility model; Figures 31A-31D It is a schematic diagram of the combination process of the driving force receiving member and the force output member involved in the thirteenth embodiment of the utility model.

[0215] On the basis of the eleventh and twelfth embodiments, this embodiment further optimizes the structure of the auxiliary component 4y.

[0216] As described above, the auxiliary part 4y is configured to rotate freely around the rotation axis L21 relative to the main part 4x. Before the driving force receiving part 4 is combined with the force output part 203, the stop position of the auxiliary part 4y relative to the main part 4x along the rotation direction r will be random, that is, the position of the separation part 4y2 relative to the main part 4x is uncertain.

[0217] In order to enable the separation member 4y2 to accurately enter between the driving portion 180h / driving force output surface 180d and the braking portion 203a (third space K3), the driving force receiving member 4 in this embodiment adopts the following solution.

[0218] The auxiliary member 4y also includes at least one auxiliary protrusion 4y5 protruding from the ring body 4y1, and the auxiliary protrusion 4y5 is used to assist the separator 4y2 and / or the driving surface 464 to reach a predetermined position, and the predetermined position is specifically that along the rotation direction r, the separator 4y2 enters the third space K3, the convex block 462 provided with the driving surface 464 enters the second space K2, and the driving surface 464 is opposite to at least one of the outer output surface 204g and the inner output surface 208f. When the auxiliary protrusion 4y5 is provided in plurality, preferably, the auxiliary protrusion 4y5 is provided as four spaced apart distributions along the circumferential direction of the auxiliary member 4y, and more preferably, the four auxiliary protrusions 4y5 are distributed in the circumferential direction of the auxiliary member 4y in an equidistant manner.

[0219] like Fig.31A As shown, when the driving force receiving member 4 approaches the force output member 203 along the rotation axis L21 / M1, the separation member 4y2 is not opposite to the third space K3 along the rotation axis L21 / M1, and the separation member 4y2 deviates to be opposite to the second space K2; as the driving force receiving member 4 continues to move, as shown in FIG. Fig.31B As shown, the auxiliary protrusion 4y5 abuts against the driving portion 180h and / or the braking portion 203a, and when the processing box C reaches the installation position, the auxiliary protrusion 4y5 still abuts against the driving portion 180h and / or the braking portion 203a.

[0220] like Fig.31C As shown in FIG. 1 , when the force output member 203 starts to rotate along the rotation direction r, the separator 4y2 starts to abut against the downstream surface (the outer output surface 204g and the inner output surface 208f) of the braking portion 203a. As the force output member 203 continues to rotate, the braking portion 203a is pressed by the separator 4y2 and moves toward the direction close to the flange portion 180a (towards the inside of the cylindrical portion 180c) until the braking portion 203a passes over the tip portion 4y22 of the separator 4y2; then, the braking portion 203a starts to abut against the guide surface 463, as shown in FIG. Fig.31D As shown, the separation member 4y2 enters the third space, and along the rotation direction r, the braking portion 203a gradually moves away from the driving portion 180h.

[0221] Similarly, in the process of the driving force receiving member 4 approaching the force output member 203, along the rotation axis L21 / M1, no matter the protrusion 462 is directly opposite to the second space K2, or opposite to the downstream surface 204g / 208f of the braking portion 203a, or opposite to the first braking end surface 204y and / or the second braking end surface 208y, or opposite to the driving portion 180h, as long as the force output member 203 starts to rotate along the rotation direction r, the protrusion 462 can directly enter the second space K2, or can enter the second space K2 by pressing the force output member 203, and the driving surface 464 can eventually abut against the downstream surface of the braking portion 203a.

[0222] When the driving force receiving member 4 is configured such that the driving surface 464 abuts against the outer output surface 204g to receive the driving force, in an extreme case, when the driving force receiving member 4 approaches the force output member 203, along the rotation axis L21 / M1, the projection 462 is just opposite to the third space K3. To prevent the projection 462 from entering the third space K3, it is achievable that along the rotation direction r, the minimum size of the fourth surface 4621 is greater than the distance s. When the extreme case occurs, the fourth surface 4621 can abut against the driving end surface 180y and the first braking end surface 204y at the same time, and as the force output member 203 rotates, the projection 462 can still enter the second space K2.

[0223] [Example 14]

[0224] Fig.32 It is a stereoscopic view of the driving force receiving member involved in the fourteenth embodiment of the present utility model.

[0225] Similar to the inventive concept of Example thirteen, along the rotation direction r, the auxiliary part 4y is provided with a plurality of separation parts 4y2 spaced apart from each other, when the driving force receiving part 4 approaches the force output part 203 along the rotation axis L21 / M1, any one of the plurality of separation parts 4y2 can enter the third space K3 along the rotation axis L21 / M1, and after the protrusion 462 provided with the driving surface 464 enters the second space K2, the driving force receiving part 4 can smoothly receive the driving force output by the force output part 203, and the noise that may be emitted by the imaging device is eliminated.

[0226] Similar to the twelfth embodiment, after the driving force receiving member 4 in this embodiment and the thirteenth embodiment is combined with the force output member 203, the braking surface 465 is combined with the braking portion 203a, and by utilizing the inclined surface structure of the braking surface 465, the tendency of the braking portion 203a to move toward the flange portion 180a is prevented, and the driving surface 464 can stably receive the driving force.

[0227] Among the multiple separating parts 4y2, except the separating part 4y2 entering the third space K3, other separating parts 4y2 can be regarded as the auxiliary protrusions 4y5 in Example thirteen. Similarly, a plurality of separating parts 4y2 equivalent to the auxiliary protrusions 4y5 can also be provided. Along the circumferential direction of the auxiliary part 4y, four auxiliary protrusions 4y5 are distributed at intervals. Preferably, the four auxiliary protrusions 4y5 are distributed at equal intervals along the circumferential direction of the auxiliary part 4y.

[0228] Furthermore, the separating parts 4y2 can also be set to five or six, and the five or six separating parts 4y2 are evenly spaced along the circumferential direction of the auxiliary part 4y. When the number of separating parts 4y2 is less than four, the separating parts 4y2 may not be able to enter the third space K3 and cause misalignment in combination. When the number of separating parts 4y2 is more than six, the separating parts 4y2 may interfere with the force output part 203 and cause the driving force receiving part 4 and the force output part 203 to fail to combine smoothly.

[0229] [Example 15]

[0230] Fig.33A is a three-dimensional diagram of a driving force receiving member involved in Embodiment 15 of the present utility model; Fig.33B It is a side view when viewed along a direction perpendicular to the rotation axis of the driving force receiving member involved in the fifteenth embodiment of the present utility model.

[0231] Based on the inventive concept of the above embodiment, the structure of the separating member 4y2, the structure of the protrusion 462 and the structure of the flange portion 47 of the driving force receiving member 4 in this embodiment are different from those of the above embodiment, and are described below respectively.

[0232] The protrusion 462 in this embodiment is provided with a driving surface 464 that can be combined with the outer output surface 204g or the inner output surface 208f of the braking portion 203a. Preferably, the protrusion 462 is also provided with a sub-driving surface 464a adjacent to the driving surface 464, and the sub-driving surface 464a is used to abut against the plane 208g and receive the driving force of the plane 208g. Furthermore, the driving surface 464 can also be called the main driving surface, and the sub-driving surface 464a can also be called the slave driving surface.

[0233] The driving force receiving member 4 can receive the driving force by causing at least one of the main driving surface 464 and the secondary driving surface 464 a to abut against the braking portion 203 a , so that the driving force receiving member 4 can stably receive the driving force.

[0234] The separator 4y2 includes a separator body 4y21 and a tip portion 4y22 which are combined with each other, wherein the separator body 4y21 is provided with the above-mentioned guide surface 463 and the barbed surface 46f, and the tip portion 4y22 extends from the guide surface 463 in a direction further away from the carrier 4y1. Preferably, the tip portion 4y22 is arranged to be conical, and along the rotation direction r, the tip portion 4y22 is located upstream of the separator 4y2, and the guide surface 463 extends from the separator body 4y21 to the tip portion 4y22. Along the rotation axis L21, the farther the tip portion 4y22 is from the carrier 4y1, the smaller its volume is, so that when the driving force receiving member 4 begins to combine with the force output member 203, the tip portion 4y22 can enter the third space K3 faster and more accurately.

[0235] In the process of combining the driving force receiving member 4 with the force output member 203, a part of the flange portion 47 is used to guide the braking portion 203a, so that the braking portion 203a can always reach the upstream side of the main driving surface 464 and / or the slave driving surface 464a, and the part of the flange portion 47 can be regarded as an embodiment of the braking portion guide member, and specifically, the flange portion 47 is arranged to extend radially outward from the outer surface of the center column 45. Preferably, the two flange portions 47 are arranged radially opposite to each other on the outer surface of the center column 45, and a guide groove 472 is formed between the two flange portions 47 along the rotation direction r, and the surface of the flange portion 47 facing the guide groove 472 is formed as a positioning guide surface 471; more preferably, along the rotation direction, the main driving surface 464 / slave driving surface 464a is located downstream of at least a part of the guide groove 472 / positioning guide surface 471. In some embodiments, the brake guide 47 may not extend radially outward from the outer surface of the center column 45, but may be recessed radially inward from the outer surface of the center column 45, as long as the guide groove 472 and / or positioning guide surface 471 can be formed.

[0236] Preferably, Fig.33B As shown, when the connecting part 41 or the chassis 42 is taken as a reference, along the rotation axis L21, the separating member 4y2 extends farther than the protrusion 462, that is, along the rotation axis L21, the separating member 4y2 protrudes farther than the main driving surface 464 / the slave driving surface 464a. In this way, when the driving force receiving member 4 and the force output member 203 approach each other, the separating member 4y2 first enters the third space K3 to complete the separation of the driving part 180h and the braking part 203a, and then the main driving surface 464 / the slave driving surface 464a abuts against the corresponding position of the braking part 203a. This structure can effectively prevent the separating member 4y2 from being unable to separate the driving part 180h from the braking part 203a after the main driving surface 464 / the slave driving surface 464a abuts against the corresponding position of the braking part 203a first, and finally the imaging device produces unacceptable noise during operation.

[0237] like Figure 34A-Figure 37CAs shown, before the driving force receiving member 4 and the force output member 203 begin to combine, along the rotation axis L21, the tip portion 4y22 is opposite to the third space K3, and the protrusion 462 is opposite to the second space K2. As the driving force receiving member 4 and the force output member 203 gradually approach each other, the tip portion 4y22 begins to enter the third space K3, and then the braking portion 203a begins to be guided by the guide surface 463. Along the rotation direction r, the driving portion 180h and the braking portion 203a gradually separate from each other, and the outer output surface 204g and the inner output surface 208f gradually approach the main driving surface 464, and the plane 208g gradually approaches the slave driving surface 464a. Finally, the separating member 4y2 enters the third space K3, the protrusion 462 enters the second space K2, and the driving force receiving member 4 and the force output member 203 complete the combination.

[0238] Further, such as Fig.34B , Fig.34C , Fig.35B , Fig.35C , Fig.36B , Fig.36C , Fig.37B and Fig.37C As shown, when the driving force receiving member 4 and the force output member 203 begin to combine, the inward protrusion 208e in the braking portion 203a enters the guide groove 472 and is guided by the positioning guide surface 471. Therefore, the relative position of the main body 4x of the driving force receiving member 4 and the force output member 203 is determined. It can be seen that the guide groove 472 / positioning guide surface 471 plays a role in positioning the main driving surface 464 and / or the slave driving surface 464a by guiding the inward protrusion 208e. Along the rotation axis L21, the closer the flange portion 47 is to the free end 451 of the center column, the earlier the inward protrusion 208e can be guided by the guide groove 472 / positioning guide surface 471. Therefore, the combination of the driving force receiving member 4 and the force output member 203 is smoother.

[0239] Specifically, along the rotation direction r, since the outer output surface 204g and the inner output surface 208f are both located downstream of at least a portion of the inward protrusion 208e, and the main drive surface 464 and the slave drive surface 464a are located downstream of at least a portion of the guide groove 472, then, when the inward protrusion 208e is guided by the guide groove 472 / the guide positioning surface 471, along the rotation axis L21, at least a portion of the main drive surface 464 and at least a portion of the slave drive surface 464a will be opposite to the second space K2, and along the rotation direction r, the active surface 464 and the slave drive surface 464a will be opposite to the braking portion 203a, so that the driving force receiving member 4 and the force output member 203 can be combined more smoothly.

[0240] Before the driving force receiving member 4 and the force output member 203 begin to engage, along the rotation axis L21, when the tip portion 4y22 is not opposite to the third space K3, the braking portion 203a can be guided by the guide groove 472 / guide positioning surface 471 through the inward protrusion 208e to determine the relative position of the driving force receiving member 4 and the force output member 203, and then, the protrusion 462 provided with the main driving surface 464 and the slave driving surface 464a can also be opposite to the second space K2, and as the force output member 203 rotates , the separation member 4y2 can also enter the third space K3 together with the tip portion 4y22. It can be seen that even if the driving force receiving member 4 is not provided with the auxiliary member 4y, as long as the guide groove 472 / guide positioning surface 471 is provided, the driving force receiving member 4 can be combined with the force output member 203. Without considering that the imaging device may produce unacceptable noise due to the proximity of the driving part 180h and the braking part 203a, the driving force receiving member 4 can still be driven by the force output member 203 to work.

[0241] In the case where the auxiliary member 4y is provided, when the guide groove 472 / the guide positioning surface 471 guides the inner protrusion 208e so that the main driving surface 464 and the secondary driving surface 464a are opposite to the braking portion 203a, but the tip portion 4y22 has not yet entered the third space K3, the position of the tip portion 4y22 may be as follows:

[0242] Along the rotation axis L21, the tip portion 4y22 is opposite to the braking portion 203a. As the force output member 203 rotates, the tip portion 4y22 passes over the braking portion 203a and enters the third space K3.

[0243] Along the rotation axis L21, the tip portion 4y22 is opposite to the driving portion 180h. As the force output member 203 rotates, the tip portion 4y22 first enters the second space K2, and then enters the third space K3 after crossing the braking portion 203a.

[0244] [Example 16]

[0245] Fig.38 It is a stereoscopic view of the driving force receiving member involved in the sixteenth embodiment of the present utility model.

[0246] In this embodiment, the structure of the separator 4y2 is restored to be the same as that of the eleventh embodiment, that is, the separator 4y2 is not provided with a tip portion 4y22.

[0247] As described above, during the combination of the driving force receiving member 4 and the force output member 203, the tip portion 4y22 can enter the third space K3 faster and more accurately, so that the separation member 4y2 as a whole can enter the third space K3 more smoothly, and finally the driving part 180h and the braking part 203a can be separated smoothly along the rotation direction r.

[0248] However, in the case where the tip portion 4y22 is not provided, when the driving force receiving member 4 involved in the present embodiment is combined with the force output member 203, even if the separating member 4y2 is not opposite to the third space K3 along the rotation axis L21, as the driving portion 180h rotates, the separating member 4y2 is pressed and guided by the driving portion 180h and / or the braking portion 203a, and the separating member 4y2 can eventually enter the third space K3.

[0249] [Example 17]

[0250] Fig.39 It is a stereoscopic view of the driving force receiving member involved in the seventeenth embodiment of the present utility model.

[0251] Different from the sixteenth embodiment, the driving force receiving member 4 in this embodiment is no longer provided with the flange portion 47, but the separating member 4y2 is provided with the tip portion 4y22.

[0252] During the combination of the driving force receiving member 4 and the force output member 203, along the rotation axis L21, when the tip portion 4y22 is opposite to the third space K3, the tip portion 4y22 can smoothly enter the third space, and then, the separation member 4y2 as a whole can also smoothly enter the third space; when the tip portion 4y22 is not opposite to the third space K3, as the force output member 203 rotates, the tip portion 4y22 is pressed and guided by the separation member 4y2 through the driving portion 180h and / or the braking portion 203a, and can eventually be opposite to the third space K3.

[0253] For the protrusion 462, during the combination process of the driving force receiving member 4 and the force output member 203, along the rotation axis L21, when the protrusion 462 is opposite to the second space K2, after the separation member 4y2 separates the driving part 180h and the braking part 203a along the rotation direction r, the protrusion 462 can smoothly enter the second space K2; when the protrusion 462 is not opposite to the second space K2, as the force output member 203 rotates, the protrusion 462 is pressed by the braking part 203a by the protrusion 462, and the protrusion 462 can eventually enter the second space K2.

[0254] [Embodiment 18]

[0255] Fig.40 It is a schematic diagram of the exploded components of the driving force receiving member involved in the eighteenth embodiment of the present utility model; Fig.41 It is a cross-sectional view of the driving force receiving member involved in the eighteenth embodiment of the present utility model cut along a plane passing through the rotation axis thereof.

[0256] As described above, during the combination process of the driving force receiving member 4 and the force output member 203, when the separating member 4y2 cannot smoothly enter the third space K3, the separating member 4y2 will abut against the driving part 180h and / or the braking part 203a. In order to prevent the separating member 4y2 from abutting against the driving part 180h and / or the braking part 203a to exceed the maximum deformation of the first spring 210 / the second spring 211, thereby causing the driving force receiving member 4 and the force output member 203 to be unable to combine smoothly, the auxiliary member 4y / separating member 4y2 in this embodiment is configured to be movable along the rotation axis L21.

[0257] As shown in the figure, under the inventive concept of the above-mentioned auxiliary part 4y, a compression spring 49 as a retaining member is arranged between the auxiliary part 4y and the main body 4x. Specifically, the driving force receiving part 4 includes a base 412 arranged in the connecting part 41, a first step surface 435 arranged on the base 412, an intermediate part 430 extending from the base 412 along the rotation axis L21, and a coupling part 44 connected to the intermediate part 430. The base 412 is formed as a part of the main body 4x, and an auxiliary part accommodating part 411 that can accommodate the auxiliary part 4y is formed between the base 41 and the inner wall of the connecting part 41. Specifically, along the radial direction of the driving force receiving part 4, the connecting part 41 surrounds at least a part of the base 412 on the outside of the base 412, and the auxiliary part accommodating part 411 is located between the connecting part 41 and the base 412.

[0258] Along the radial direction of the driving force receiving member 4, the diameter of the bottom plate 441 of the coupling portion is larger than the diameter of the middle member 430, and the diameter of at least a portion of the base 412 is larger than the diameter of the middle member 430, so that the limiting portion 434 is formed between the bottom plate 441 and the base 412, and one end of the compression spring 49 abuts against the first step surface 435, and the other end abuts against the auxiliary member 4y / limited portion 4y4.

[0259] When the auxiliary part 4y / separating part 4y2 abuts against the driving part 180h and / or the braking part 203a, even if the first spring 210 / the second spring 211 has reached the maximum deformation, the auxiliary part 4y / separating part 4y2 can be retracted toward the direction close to the connecting part 41 by compressing the compression spring 49 to undergo elastic deformation. When the auxiliary part 4y / separating part 4y2 no longer abuts against the driving part 180h and / or the braking part 203a, the compression spring 49 releases the elastic force, and the auxiliary part 4y / separating part 4y2 extends toward the direction away from the connecting part 41.

[0260] Preferably, along the rotation axis L21, the driving force receiving member 4 also includes a second step surface 436 which is arranged farther away from the connecting portion 41 than the first step surface 435, and the bottom plate 441 is formed as a part of the main body 4x. Therefore, the bottom plate 441 can also be regarded as an upper limit plate 437 of the limiting portion 434, and the component forming the second step surface 436 can be regarded as a lower limit plate of the limiting portion 434, and the limited portion 4y4 can move along the rotation axis L21 between the lower surface 4371 of the upper limit plate 437 and the second step surface 436 of the lower limit plate.

[0261] In some embodiments, the second step surface 436 can also be flush with the first step surface 435. In this way, the structure of the driving force receiving member 4 will become simple, and the compression spring 49 and the limited portion 4y4 can move between the lower surface 4371 of the upper limit plate 437 and the second step surface 436 of the lower limit plate.

[0262] According to the inventive concept of this embodiment, the compression spring 49 can also be replaced by an elastic arm, sponge, rubber, etc., or the compression spring 49 can be replaced by a tension spring to achieve the function of the above-mentioned retaining member.

[0263] As described above, the separating member 4y2 is configured to be elastically movable relative to the connecting portion 41 / photosensitive drum along the rotation axis L21, so that the separating member 4y2 can avoid abutting the driving portion 180h and the braking portion 203a so that they cannot move along the rotation axis M1, thereby improving the flexibility of the combination of the driving force receiving member 4 and the force output member 203 and effectively preventing interference between the driving force receiving member 4 and the force output member 203.

[0264] [Example 19]

[0265] Fig.42 It is an exploded schematic diagram of the driving force receiving member after the driving force receiving member involved in the nineteenth embodiment of the present utility model is separated from the driving end cover;

[0266] Fig.43 It is a cross-sectional view taken along the EE direction through the rotation axis of the driving force receiving member involved in the nineteenth embodiment of the present utility model.

[0267] As shown above, the charging member is used to charge the surface of the photosensitive drum 21, and the charging member is rotated by contacting the photosensitive drum 21 and driven by the friction between the surface of the photosensitive drum 21 and the surface of the charging member. To ensure that the photosensitive drum 21 and the charging member are in good contact, the processing box also includes an elastic member for applying a force to the charging member so that the charging member approaches the photosensitive drum 21. The elastic member can be a compression spring that applies a pushing force to the charging member, or a tension spring that applies a tension force to the charging member. Under the action of the force applied by the elastic member, the surface of the charging member is in good contact with the surface of the photosensitive drum 21. The following description takes the elastic member as a compression spring as an example. When the elastic member 28 is set as a tension spring, the structures involved in this embodiment and embodiment 20 and embodiment 21 are also applicable.

[0268] It can be understood that the elastic force applied to the charging member by the elastic member 28 will be transmitted to the driving force receiving member 4, and the driving force receiving member 4 is exposed from the driving end cover 300. Under the action of this elastic force, the friction between the base 43 of the driving force receiving member 4 and the driving end cover 300 will also increase accordingly, especially in the above-mentioned driving force receiving member 4 provided with the auxiliary member 4y, the auxiliary member 4y is located radially outside the base 43; that is, in the driving force receiving member 4 provided with the auxiliary member 4y, the friction between the auxiliary member 4y and the driving end cover 300 and / or the friction between the auxiliary member 4y and the driving force receiving part 44 / the main body 4x will increase, and the auxiliary member 4y needs to be arranged to rotate relative to the main body 4x / the processing box shell / the photosensitive drum 21, and the higher the flexibility of the rotation of the auxiliary member 4y, the smoother the combination process of the driving force receiving member 4 and the force output member 203.

[0269] To this end, based on the above-mentioned embodiment, one of the purposes of this embodiment is to prevent the increase of resistance during the rotation of the auxiliary part 4y, thereby maintaining the rotation flexibility of the auxiliary part 4y.

[0270] The driving force receiving member 4 includes a coupled portion 4z and a coupling portion 44 coupled to each other, and an auxiliary member 4y rotatable relative to the coupling portion 44, the driving force receiving member 4 has a rotation axis L21, and the auxiliary member 4y is located between the coupling portion 44 and the coupled portion 4z along a radial direction perpendicular to the rotation axis L21. Specifically, the coupled portion 4z includes a connecting portion 41, a chassis 42, and a base 43, the base 43 is connected to at least one of the connecting portion 41 and the chassis 42, and in the case where the chassis 42 is not provided, the base 43 will be directly connected to the connecting portion 41, as described above, the driving force receiving member 4 can also be regarded as including a main body 4x and a connecting portion 41 and / or a chassis 42 connected to the main body 4x, the main body 4x including a base 43 and a coupling portion 44 coupled to each other.

[0271] The base 43 is cylindrical as a whole, and includes a radially arranged base outer wall 438 and a base inner wall 439, wherein the base outer wall 438 is farther away from the rotation axis L21 than the base inner wall 439, and along the radial direction of the driving force receiving member 4, the base outer wall 438 and the base inner wall 439 are arranged at intervals, and a spacing groove 43c is formed therebetween, and the base inner wall 439 is provided with a protrusion 433 protruding toward the rotation axis L21, and the coupling part 44 is provided with a groove that can cooperate with the protrusion 433, or the protrusion 433 is provided on the coupling part 44, and the groove is provided on the base inner wall 439, as long as the driving force can be transmitted between the coupling part 44 and the coupled part 4z.

[0272] The auxiliary member 4y in this embodiment can adopt the auxiliary member structure in any of the above embodiments. For example, the auxiliary member 4y includes a carrier 4y1, a separation member 4y2 protruding from the carrier 4y1, an elastic arm 4y3 connected to the carrier 4y1, and a limited portion 4y4 arranged on the elastic arm 4y3. The carrier 4y1 is annular and encloses a receiving cavity 4y6 that can accommodate the coupling portion 44. Preferably, the elastic arm 4y3 is formed by cutting a part of the carrier 4y1, that is, the elastic arm 4y3 can be regarded as a part of the carrier 4y1. In this embodiment, at least a part of the carrier 4y1 is accommodated by the spacing groove 43c, so that along the radial direction of the driving force receiving member 4, the carrier 4y1 is located between the base inner wall 439 and the base outer wall 438.

[0273] The coupling portion 44 includes a bottom plate 441, a center column 45 extending from one side of the bottom plate 441 and a driving force receiving portion 46, and a driving force transmitting portion 442 extending from the other side of the bottom plate 441, wherein the driving force transmitting portion 442 is used to be combined with the protrusion 433 to realize the driving force transmission between the coupling portion 44 and the coupled portion 4z, and at least a portion of the bottom plate 441 can be regarded as a base 461 of the driving force receiving portion 46, and the driving force receiving portion 46 also includes a protrusion 462 which is farther away from the rotation axis L21 / center column 45 than the base 461, and the protrusion 462 is used to receive the driving force.

[0274] Furthermore, the coupling portion 44 also includes a flange portion 47 for guiding the braking portion 203a. Similar to the preferred method of Example 15, a guide groove 472 is formed between the two flange portions 47, and the surface of the flange portion facing the guide groove 472 is formed as a positioning guide surface 471. In the process of coupling between the driving force receiving member 4 and the force output member 203, the inward protrusion 208e in the braking portion 203a enters the guide groove 472 and is guided by the positioning guide surface 471, so that the relative position of the main body 4x of the driving force receiving member 4 and the force output member 203 is determined. Finally, the driving force receiving member 4 and the force output member 203 can be smoothly coupled.

[0275] In some embodiments, the combining portion 44 and the combined portion 4z are formed separately, such as Fig.42 As shown, the coupling part 44 also includes a guide coupling part 443 arranged on the same side as the driving force transmission part 442 and a clamping protrusion 444 arranged at the end of the guide coupling part 443. Through the combination of the clamping protrusion 444 and the coupled part 4z, the coupling part 44 and the coupled part 4z are combined. Specifically, the clamping protrusion 444 is combined with the connecting part 41 or the chassis 42.

[0276] The driving end cover 300 includes an end cover body 301 and a mounting hole 302 disposed on the end cover body 301. The driving force receiving member 4 is exposed to the outside through the mounting hole 302. The mounting hole 302 has an inner surface 3021 of the mounting hole. Fig.43 As shown, in order to more clearly show the internal structure of the driving force receiving member 4 and the driving end cover 300, the driving force receiving part 44 is not shown in the figure; when the driving end cover 300 is installed, the base 43 will enter the mounting hole 302, and accordingly, the base outer wall 438, the base inner wall 439 and the carrier 4y1 located between the base outer wall 438 and the base inner wall 439 will also enter the mounting hole 302.

[0277] As described above, the carrier 4y1 is located between the outer wall 438 of the base and the inner wall 439 of the base, that is, the outer surface 4y11 of the carrier will not contact the inner surface 3021 of the mounting hole. As long as the gap between the outer wall 438 of the base and the inner wall 439 of the base is larger than the radial dimension of the carrier 4y1, the auxiliary part 4y with the carrier 4y1 will be able to rotate freely. At this time, the outer surface of the outer wall 438 of the base is in contact with the inner surface 3021 of the mounting hole. Even if the thrust force applied to the charging part by the elastic part 28 is transmitted to the base 43, it will only increase the friction between the base 43 / the outer wall 438 of the base and the inner surface 3021 of the mounting hole, and will not affect the auxiliary part 4y. It can be seen that the resistance encountered by the auxiliary part 4y during rotation will not increase, and its rotation flexibility can be maintained.

[0278] In some embodiments, the spacing grooves 43c are provided along the entire circumferential direction of the driving force receiving member 4, so that the rotation trajectory of the auxiliary member 4y will become more stable.

[0279] In other embodiments, along the circumferential direction of the driving force receiving member 4, the spacing groove 43c is only set with a predetermined curvature. Preferably, the direction of the thrust applied by the elastic member 28 to the charging member passes through the spacing groove 43c. In other words, along the radial direction of the driving force receiving member 4, the spacing groove 43c is located in the direction of the thrust applied by the elastic member 28 to the charging member. Similarly, the auxiliary member 4y will not contact the inner wall 3021 of the mounting hole, the resistance encountered by the auxiliary member 4y during rotation can be reduced, and its rotation flexibility can be greatly improved. It can be seen that along the radial direction of the driving force receiving member 4, at least a portion of the spacing groove 43c / base outer wall 438 is located in the direction of the thrust applied by the elastic member 28 to the charging member, or, in other words, at least a portion of the spacing groove 43c / base outer wall 438 is located in the direction of the elastic member 28 pushing the charging member.

[0280] In other embodiments, the spacing groove 4c can also be provided on the auxiliary part 4y, and accordingly, a protrusion for combining with the spacing groove 4c is provided on the combined part 4z. For example, the above-mentioned base outer wall 438 or the base inner wall 439 can be respectively regarded as an embodiment of the protrusion. When the base inner wall 439 is combined with the spacing groove 4c provided on the auxiliary part 4y, the base outer wall 438 can be cancelled. Alternatively, when the base outer wall 438 is combined with the spacing groove 4c provided on the auxiliary part 4y, the outer surface of the carrier 4y1 will be directly opposite to the inner wall 3021 of the mounting hole. Even if the auxiliary part 4y is subjected to the forced thrust from the elastic part 28, the resistance encountered by the auxiliary part 4y during rotation will not increase, and its rotation flexibility can be maintained.

[0281] Furthermore, lubricant may be applied between the outer surface of the carrier 4y1 and the inner wall 3021 of the mounting hole, or the outer surface of the carrier 4y1 and the inner wall 3021 of the mounting hole may be set as smooth surfaces, thereby reducing the resistance encountered by the auxiliary component 4y during rotation.

[0282] [Example 20]

[0283] Fig.44 This is a state diagram of the driving force receiving member and the driving end cover after being separated from each other according to the twentyth embodiment of the utility model; Fig.45 It is a cross-sectional view taken along the EE direction through the rotation axis of the driving force receiving member involved in the twenty-second embodiment of the present utility model.

[0284] In this embodiment, the driving force receiving member 4 does not need to be modified as described in the nineteenth embodiment, and accordingly, the structure of the driving end cover 300 is changed.

[0285] like Fig.44 and Fig.45As shown, the driving force receiving member 4 has a rotation axis L21, includes a connecting portion 41, a chassis 42, a base 43, a coupling portion 44 and an auxiliary member 4y rotatable relative to the coupling portion 44. Along the radial direction perpendicular to the rotation axis L21, the size of the chassis 42 is larger than that of the connecting portion 41 and the base 43, and the auxiliary member 4y is located radially outside the coupling portion 44, or in other words, the coupling portion 44 is located in the accommodating cavity 4y6 of the auxiliary member 4y.

[0286] The driving end cover 300 includes an end cover body 301 and a mounting hole 302 provided on the end cover body 301, through which the driving force receiving member 4 is exposed. Further, the driving end cover 300 also includes a blocking portion 303 extending from the end cover body 301. When the driving end cover 300 is installed, at least a portion of the base 43, at least a portion of the auxiliary member 4y, and the driving force receiving portion 44 ( Fig.45 At least a portion of the driving force receiving member 4 (not shown) enters the mounting hole 302, and at the same time, the blocking portion 303 abuts against the driving force receiving member 4.

[0287] Preferably, the blocking portion 303 abuts against the bottom plate 42, such as Fig.45 As shown, along the radial direction, the blocking portion 303 is located on the outside of the mounting hole 302; when the charging member is squeezed by the elastic force applied by the elastic member 28 to squeeze the photosensitive drum 21, the squeezing force exerted on the driving force receiving member 4 will be eliminated due to the abutment between the blocking portion 303 and the chassis 42, and the position of the auxiliary member 4y in the mounting hole 302 will not change, that is, the free rotation state of the auxiliary member 4y will not be affected, and accordingly, the resistance of the auxiliary member 4y during rotation will not increase, and its rotation flexibility can be maintained.

[0288] More preferably, along the pushing direction k of the pushing force applied by the elastic member 28 to the charging member, the blocking portion 303 abuts against the chassis 42. At this time, the free rotation state of the auxiliary member 4y can be better maintained. It can be seen that along the radial direction of the driving force receiving member 4, at least a portion of the blocking portion 303 is located in the pushing direction k of the pushing force applied by the elastic member 28 to the charging member, or in other words, at least a portion of the blocking portion 303 is located in the pushing direction k of the elastic member 28 to push the charging member.

[0289] In some embodiments, the blocking portion 303 can also be configured to abut against other parts of the driving force receiving member 4. For example, the blocking portion 303 abuts against the connecting portion 41, which can also prevent the increase in resistance during the rotation of the auxiliary member 4y, thereby maintaining the rotation flexibility of the auxiliary member 4y.

[0290] [Example 21]

[0291] Fig.46 It is an exploded schematic diagram of the driving force receiving member involved in the twenty-first embodiment of the utility model; Fig.47 is a three-dimensional diagram of the driving end cover involved in Embodiment 21 of the present utility model; Fig.48 It is a cross-sectional view taken along the EE direction through the rotation axis of the driving force receiving member involved in Example 21 of the utility model.

[0292] In this embodiment, the structure of the driving force receiving member 4 and the structure of the driving end cover 300 are changed at the same time, but the auxiliary member 4y is not limited and can adopt the structure described in any of the above embodiments. As mentioned above, the driving force receiving member 4 can also be regarded as including a coupled part 4z and a coupling part 44 coupled to each other and an auxiliary member 4y rotatable relative to the coupling part 44, wherein the driving force receiving member 4 has a rotation axis L21, the coupled part 4z includes a connecting part 41, a chassis 42 and a base 43, the base 43 is connected to at least one of the connecting part 41 and the chassis 42, and when the chassis 42 is not provided, the base 43 will be directly connected to the connecting part 41, and the auxiliary member 4y is located radially outside the coupling part 44, or in other words, the coupling part 44 is located in the accommodating cavity 4y6 of the auxiliary member 4y.

[0293] In this embodiment, the structure of the coupling part 44 is the same as that of the coupling part in the nineteenth embodiment. An active cavity 432 and a protrusion 433 located in the active cavity 432 are formed in the base 43. The coupling method of the coupling part 44 and the base 43 is the same as that in the nineteenth embodiment, which will not be repeated here.

[0294] Furthermore, the driving force receiving member 4 also includes a base 412 arranged in the connecting portion 41 and a first step surface 435 arranged on the base 412. Along the rotation axis L21, at least a portion of the base 43 is extended from the base 412; the coupled portion 4z is also provided with a limiting groove 413, and the driving end cover 300 is provided with a limited protrusion 304 combined with the limiting groove 413. Through the combination of the limited protrusion 304 and the limiting groove 413, the movement of the photosensitive drum 21 in the radial direction can be limited.

[0295] The auxiliary part 4y is supported by the first step surface 435. Along the radial direction of the driving force receiving part 4, the limiting groove 413 is located on the radial outside of the auxiliary part 4y. Therefore, the position of the auxiliary part 4y in the mounting hole 302 will not change, and the free rotation state of the auxiliary part 4y will not be affected. Accordingly, the resistance of the auxiliary part 4y during rotation will not increase, and its rotation flexibility can be guaranteed.

[0296] Specifically, the limiting groove 413 can be set on the connecting portion 41 or on the chassis 42. Along the radial direction, the limiting groove 413 is located radially outside the base 43, or in other words, the limiting groove 413 is farther away from the rotation axis L21 than the base 43, and in the radial direction, the first step surface 435 is formed between the limiting groove 413 and the base 43. Fig.47 As shown, the driving end cover 300 includes an end cover body 301, a mounting hole 302 arranged on the end cover body 301, and a limited protrusion 304 extending from the end cover body 301, wherein the limited protrusion 304 is used to combine with the limiting groove 413. Preferably, the limited protrusion 304 is extended from the radial edge of the mounting hole 302 along the rotation axis L21, that is, the limited protrusion 304 encloses the mounting hole 302.

[0297] In some embodiments, the positions of the limiting groove 413 and the limited protrusion 304 can also be interchanged, that is, the limiting groove 413 is set on the driving end cover 300, and the limited protrusion 304 is set on the combined part 4z; the same as the above-mentioned embodiment, along the radial direction of the driving force receiving member 4, at least a portion of the limiting groove 413 and one of the limited protrusions 304 is located in the direction of the thrust force applied by the elastic member 28 to the charging member, or in other words, at least a portion of the limiting groove 413 and one of the limited protrusions 304 is located in the direction in which the elastic member 28 pushes the charging member.

[0298] In summary, along the radial direction of the driving force receiving member 4, by arranging limiting members and restricted members that can be combined with each other, it is possible to prevent the elastic member 28 from applying a force toward the photosensitive drum 21 to the charging member, so that the driving force receiving member 4 coaxially arranged with the photosensitive drum 21 is indirectly forced to be pushed, thereby causing the auxiliary member 4y on the driving force receiving member 4 to be squeezed against the inner wall 3021 of the mounting hole on the driving end cover 300, or the auxiliary member 4y to be squeezed against the driving force receiving part 44 / the main body 4x, resulting in an increase in the rotational resistance of the auxiliary member 4y and a decrease in the rotational flexibility of the auxiliary member 4y. Finally, the driving force receiving member 4 cannot be smoothly combined with the force output member 203.

[0299] Based on the inventive concept of the utility model, along the radial direction of the driving force receiving member 4, the outer bearing surface 4y11 of the auxiliary member 4y is arranged not to contact the inner wall 3021 of the mounting hole, that is, a gap is formed between the outer surface 4y11 and the inner wall 3021 of the mounting hole, or, even if the outer surface 4y11 contacts the inner wall of the mounting hole 3021, no extrusion is generated between the two. In this way, the rotational resistance of the auxiliary member 4y will not increase, and the rotational flexibility of the auxiliary member 4y can be maintained. Therefore, the driving force receiving member 4 and the force output member 203 can be smoothly combined.

[0300] After the limiting member and the restricted member are combined with each other, even if the driving force receiving member 4 indirectly receives the force from the elastic member 28, the auxiliary member 4y will not be squeezed against the inner wall 3021 of the mounting hole, or the auxiliary member 4y will not be squeezed against the driving force receiving part 44 / the main body 4x, and the friction force between the auxiliary member 4y and the inner wall 3021 of the mounting hole and / or the friction force between the auxiliary member 4y and the driving force receiving part 44 / the main body 4x will not increase. Therefore, the resistance during the rotation of the auxiliary member 4y will not increase, and the rotation flexibility of the auxiliary member 4y can be maintained.

[0301] Preferably, along the approach direction k where the elastic member 28 forces the charging member to approach the photosensitive drum 21, at least a portion of the restricted member and one of the restricting members is located in the approach direction k, that is, along the radial direction of the driving force receiving member, the restricting member and the restricted member are combined at least in the approach direction k.

[0302] According to Example 20 and Example 21, the restricted member may be a spacing groove 43c arranged on the coupled part 4z, or a chassis 42 / connecting part 41 arranged on the coupled part 4z, or a limiting groove 413 arranged on the coupled part 4z. The restricted member may be a part of the auxiliary member 4y itself, or a blocking part 303 arranged on the driving end cover 300, or a limited protrusion 304 arranged on the driving end cover 300. In a deformable embodiment, the positions of the restricted member and the restricted member may be interchangeable.
