[0066] The embodiments of the present application will be described in detail below with reference to the drawings. For the purpose of convenience, the numbering and structure of the processing cartridge and its components mentioned in the patent application of the background art will be directly quoted in the following description. It can be understood that the first rotating member 11 and / or the second rotating member 21 mentioned in the patent application of the background art can be directly driven by the driving force receiving member X4 or indirectly driven, and the processing cartridge C can simultaneously include the first unit 100 and the second unit 200 or only include any one of the first unit 100 and the second unit 200. The processing cartridge C can be detachably installed into an image forming apparatus provided with a force output member. The processing cartridge C includes a housing, a rotating member rotatably arranged in the housing, and a driving force receiving member X4 located at a longitudinal end of the housing. The side provided with the driving force receiving member X4 is referred to as a driving end C1, and the other end opposite to the driving end C1 is referred to as a non-driving end C2. A driving end cover 300 is installed at the driving end C1, and the driving force receiving member X4 is exposed from the driving end cover C1. A non-driving end cover 400 is installed at the non-driving end C2. The first rotating member 11 can be a developing member, and the second rotating member 21 can be a photosensitive member. However, the first rotating member 11 and the second rotating member 21 can also be other components in the processing cartridge that need to be rotated, such as a charging member for charging the photosensitive member, a supply member for supplying a developer to the developing member, an agitating member for agitating the developer, and the like, as long as the driving force receiving member X4 can receive the driving force from the force output member provided in the image forming apparatus and drive the rotating member to rotate.

[0067] For the purpose of making the following description clearer, it is necessary to further describe the force output member 203 in combination with the drawings of the patent application of the background art (the cited patent application).

[0068] As shown in FIG. 43 of the cited patent application, the force output member 203 further comprises a first spring (drum drive coupling spring) 210 and a second spring (brake engagement spring) 211. The first spring 210 abuts against the brake transmission member 207, and the flange portion 207a of the brake transmission member 207 abuts against the second brake engagement member 208. Meanwhile, the protrusion 207f of the brake transmission member 207 also abuts against the contact surface 180f (as shown in FIG. 44 of the cited patent) of the drive force output member 180. The second spring 211 abuts against the flange portion 204a of the first brake engagement member 204, and the first brake engagement member 204 and the second brake engagement member 208 are coupled by the rotation stop recess 204c and the rotation stop protrusion 208c. Thus, the first brake engagement member 204 and the second brake engagement member 208 can rotate together around the axis M1, and the first brake engagement member 204, the second brake engagement member 208 and the drive force output member 180 can all retract along the axis M1, i.e. move in the direction indicated by M1A in FIG. 48 of the cited patent. When the first brake engagement member 204 moves along the axis M1 in the direction indicated by M1A, the rotation stop recess 204c and the rotation stop protrusion 208c are uncoupled, and the first brake engagement member 204 and the second brake engagement member 208 can rotate freely around the axis M1. When the second brake engagement member 208 moves along the axis M1 in the direction indicated by M1A, the first brake engagement member 204 will also move along the axis M1 in the direction indicated by M1A, through the rotation stop recess 204c and the rotation stop protrusion 208c.

[0069] Further, as shown in FIG. 47 of the cited patent, in the radial direction of the drive force output member 180, the first brake engagement member 204 is located radially outward of the second brake engagement member 208. The second brake engagement member 208 further has an inward protrusion 208e protruding radially inward from the coupling engagement portion 208b, and the inward protrusion 208e is located at the free end of the second brake engagement member 208 in the direction indicated by M1B (as shown in FIG. 48) which is opposite to the direction indicated by M1A. In the rotation direction of the force output member 203, the drive force output portion 180h is opposite to the first brake engagement member 204, i.e. taking the point through which the rotation axis M1 passes as the center of a circle, a circle is drawn in the plane perpendicular to the rotation axis M1, and the circle will pass through at least part of the drive force output portion 180h and at least part of the first brake engagement member 204.

[0070] Further, the drive force output portion 180h is provided with a lower protrusion 180g on a side surface (drive force output surface) 180d facing the first brake engagement member 204, and the first brake engagement member 204 is provided with an upper protrusion 204f on a side surface facing the drive force output portion 180h, and before the process cartridge 100 is mounted, the drive force output portion 180h and the first brake engagement member 204 are brought close to each other in the rotational direction r along the rotational axis M1, and the upper protrusion 204f and the lower protrusion 180g are opposed.

[0071] As shown in Figure 3A The utility model relates to a drive force receiving piece 4 with a rotational axis L21, comprising a connecting portion 41, a base plate 42, a base 43 and a combination portion 44, along the rotational axis L21, the connecting portion 41, the base plate 42, the base 43 and the combination portion 44 are arranged in turn, the connecting portion 41 is directly or indirectly combined with the rotating piece, and is used for transmitting drive force to the rotating piece to drive the rotating piece to rotate, the base plate 42 abuts against the rotating piece, so that the drive force receiving piece 4 is positioned relative to the rotating piece, the base 43 extends from the base plate 42, and the combination portion 44 extends from the base 43 in a direction away from the base plate 42, as a simplified structure, the base plate 42 can be omitted, and the base 43 directly extends from the connecting portion 41, and more simply, the base 43 can also be omitted, and the combination portion 44 extends from the connecting portion 41.

[0072] The structure of the combination portion 44 will be described below, and other structures of the drive force receiving piece 4 are not limited herein. In order to more clearly show the structure of the drive force receiving piece according to the utility model, only the drive force receiving piece 4 is shown below, but it should be understood that the drive force receiving piece 4 can be applied to each rotating piece in the process cartridge.

[0073] [Embodiment One]

[0074] Figure 3A is a perspective view of the drive force receiving piece according to the embodiment one of the utility model; Figure 3B is a side view of the drive force receiving piece according to the embodiment one of the utility model, observed in a direction perpendicular to the rotational axis of the drive force receiving piece; Figure 3C is a side view of the drive force receiving piece according to the embodiment one of the utility model, observed along the rotational axis of the drive force receiving piece.

[0075] The combination portion 44 comprises a center column 45 and a drive force receiving portion 46 extending outward along the radial direction of the center column 45, and the rotational axis L21 passes through the center column 45, and the drive force receiving portion 46 can be arranged in one or multiple along the circumferential direction of the center column 45; further, the drive force receiving portion 46 can also be regarded as being formed along the rotational axis L21 from the base 43.

[0076] Taking one of the driving force receiving parts 46 as an example, the driving force receiving part 46 includes a base 461 connected to the central column 45 and a driving surface 464, a braking surface 465, and a contact surface 463 disposed on the base 461. Along the rotation direction of the driving force receiving member 4, the driving surface 464 and the braking surface 465 are arranged opposite to each other. During the installation of the driving force receiving member 4 towards the imaging device along with the processing box C, the contact surface 463 abuts against at least one of the coupling engagement portion 204b of the first braking engagement member 204 and the coupling engagement portion 208b of the second braking engagement member 208, causing the driving force receiving part 46 to reach the position where the driving force output surface 180d and the driving surface 464 are opposite. When the force output member 203 rotates, the driving force receiving member 4 / driving force receiving part 46 moves along... Figure 3C Rotate in the direction indicated by r.

[0077] Along the rotation direction of the driving force receiver 4, the base 461 includes an adjacent first portion 461a and a second portion 461b, wherein the driving surface 464 and the braking surface 465 are located in the first portion, and the contact surface 463 extends simultaneously in the first portion 461a and the second portion 461b. Along the radial direction of the driving force receiver 4, the first portion 461a protrudes further than the second portion 461b. Preferably, the first portion 461a and the second portion 461b are integrally formed.

[0078] In this embodiment, the contact surface 463 is formed as the end surface of the base 461, such as Figure 3B As shown, when viewed along a direction perpendicular to the rotation axis L21, the contact surface 463 is perpendicular to the rotation axis L21. Specifically, along the rotation direction of the driving force receiving member 4, the contact surface 463 includes a first contact surface 463a corresponding to the first part 461a and a second contact surface 463b corresponding to the second part 461b. Both the first contact surface 463a and the second contact surface 463b are perpendicular to the rotation axis L21. In this way, the structure of the driving force receiving part 46 can be simplified, which is beneficial to improving the production efficiency of the driving force receiving part 46 and the driving force receiving member 4 including the driving force receiving part 46.

[0079] When the process cartridge C provided with the driving force receiving member 4 is mounted, the contact surface 463 abuts against the end of the brake force output member (the first brake engagement member 204 and the second brake engagement member 208), and as the process cartridge C is further mounted, the brake force output member is compressed toward the inside of the image forming apparatus, the first brake engagement member 204 is disengaged from the brake force transmission member 207 in the background art patent application, the driving surface 464 reaches a position opposite to the driving force output surface 180d, and the brake surface 465 is not opposite to the brake force output member. When the process cartridge C is stopped, the driving force output surface 180d no longer outputs the driving force to the driving surface 464, and the brake force output member no longer applies the brake force to the brake surface 465. In the present embodiment, the contact surface 463 functions as a compression surface that compresses the brake force output member toward the inside of the image forming apparatus, and thus the contact surface 463 can also be referred to as a compression surface. During the operation of the process cartridge C, the brake force output member can be configured to apply the brake force to the brake surface 465 or not to apply the brake force to the brake surface 465.

[0080] When viewed in a direction perpendicular to the rotation axis L21, the first contact surface 463a and the second contact surface 463b can be arranged in alignment or out of alignment. When the first contact surface 463a and the second contact surface 463b are arranged out of alignment, a height difference is formed between the first contact surface 463a and the second contact surface 463b. During the mounting of the process cartridge C, the first contact surface 463a and the second contact surface 463b still compress the brake force output member toward the inside of the image forming apparatus, but because the first contact surface 463a and the second contact surface 463b are still arranged as planes perpendicular to the rotation axis L21, this structure is still advantageous in improving the production efficiency of the driving force receiving portion 46 and the driving force receiving member 4 including the driving force receiving portion 46, as compared with the guide surface X463 arranged in a spiral shape in the prior art.

[0081] Preferably, when viewed in a direction perpendicular to the rotation axis L21, the first contact surface 463a and the second contact surface 463b are arranged in alignment. More preferably, when viewed in a direction perpendicular to the rotation axis L21, the first contact surface 463a and the second contact surface 463b are integrated. That is, the first contact surface 463a and the second contact surface 463b together constitute the end surface of the driving force receiving portion 46, and the end surface is perpendicular to the rotation axis L21. With reference to the surface CP of the process cartridge housing that is farthest from the driving end C1 at the non-driving end C2, when measured in the direction of the rotation axis L21, the distance from the first contact surface 463a to the surface CP is h1, and the distance from the second contact surface 463b to the surface CP is h2, and h1 = h2. Thus, the structure of the driving force receiving portion 46 can be simplified, and this is advantageous in improving the production efficiency of the driving force receiving portion 46 and the driving force receiving member 4 including the driving force receiving portion 46.

[0084] As shown, the second part 461b is cut off, the first part 461a is reserved, the overall structure of the driving force receiving part 46 is further simplified, and similarly, along the rotation axis L21, the end face 463a of the first part 461a is the contact face, and the contact face 463a is also perpendicular to the rotation axis L21; along the radial direction of the driving force receiving member 4, the contact face 463a, the driving face 464 and the braking face 465 all extend to the end of the base 461, as shown. Figure 4B As shown, along the radial direction of the driving force receiving member 4, the contact face 463a, the braking face 465 and the driving face 464 are respectively E, F and G at the most outer points in the radial direction, and the distance from the rotation axis L21 to the points E, F and G is equal, so that the production efficiency of the driving force receiving part 46 and the driving force receiving member 4 including the driving force receiving part 46 can be improved.

Figure 5A is a side view of the driving force receiving member according to the embodiment one of the present application, viewed along the rotation axis of the driving force receiving member.

[0087] Similarly to the above deformation structure one, the end face 463a of the first part 461a is set to be not perpendicular to the rotation axis L21, but is set to be an inclined face inclined relative to the rotation axis L21 or a spiral face extending along the rotation direction of the driving force receiving member 4, and along the radial direction of the driving force receiving member 4, the guide face 463, the driving face 464 and the braking face 465 all extend to the end of the base 461, and the distance from the rotation axis L21 to the points at the most outer points in the radial direction of the contact face 463a, the braking face 465 and the driving face 464 is equal, so that the production efficiency of the driving force receiving part 46 and the driving force receiving member 4 including the driving force receiving part 46 can be improved.

[0090] Unlike the background art, the driving force receiving part 46 in the present embodiment further comprises a protruding part 463c provided on the guide surface 463, as shown in Figure 6B When measured along the direction of the rotation axis L21, the distance from the guide surface 463 to a certain fixed surface (for example, the surface of one of the base 43, the chassis 42 and the connecting part 41 perpendicular to the rotation axis L21) of the driving force receiving member 4 or to a certain fixed surface (for example, the surface CP mentioned above) of the process cartridge will no longer be a fixed value or a gradient value, but will be converted between values in size with the protrusion of the protruding part 463c, as shown in Figure 6B With the surface CP as the reference surface, along the rotation direction r, a point B1 upstream of the protruding part 463c where the guide surface 463 is located, a point B2 upstream of the protruding part 463c where the guide surface 463 intersects, and the highest point B3 of the protruding part 463c are selected, the point B1 is located at the most upstream of the rotation direction r, the point B3 is located at the most downstream of the rotation direction r, measured along the rotation axis L21, the distance from the point B1 to the surface CP is h3, the distance from the point B2 to the surface CP is h4, and the distance from the point B3 to the surface CP is h5, h3>h5>h4; during the installation of the process cartridge C, the protruding part 463c abuts against the brake force output member, which can reduce the friction between the driving force receiving member 4 and the brake force output member, so that the driving force receiving part 46 can be more easily combined with the driving force receiving member, at the same time, the protruding part 463c can also slow down the combination speed of the brake surface 465 and the shaft coupling joint part 204b / 208b in the brake force output member, so that the noise during the combination of the driving force receiving member 4 and the brake force output member can be reduced, which is also beneficial to prevent the brake force output member from being damaged.

[0091] During the installation of the process cartridge C, when the driving force output member 180 and the brake force output member are close to each other, the guide surface 463 is used to separate the driving force output surface 180d and the shaft coupling joint part 204b / 208b in the brake force output member from each other, so that the driving force output surface 180d is opposite to the driving surface 464, and the shaft coupling joint part 204b / 208b is opposite to the brake surface 465; during the working process of the process cartridge C, the driving force output surface 180d applies driving force to the driving surface 464, when the process cartridge C stops working, the driving force output surface 180d no longer outputs driving force to the driving surface 464, the shaft coupling joint part 204b / 208b applies brake force to the brake surface 465 on the downstream side of the rotation direction of the driving force receiving part 46, and the driving force receiving member 4 / the driving force receiving part 46 stops rotating.

[0095] [Embodiment Three]

[0096] Figure 8A is a perspective view of the driving force receiving member according to the third embodiment of the present application; Figure 8B is a sectional view along a plane perpendicular to the rotation axis and passing through the braking surface in the Figure 8A .

[0097] Unlike the background art, the driving force receiving part 46 in the present embodiment further comprises a flange part 47 located radially outward of at least one of the driving surface 464 and the braking surface 465, preferably, the flange part 47 extends outward along the radial direction of the guide surface 463, and along the rotation axis L21, the surface of the flange part 47 away from the base 43 / chassis 42 / connecting part 41 is coplanar with the guide surface 463, thus at least a part of the guide surface 463 can also be regarded as being located radially outward of at least one of the driving surface 464 and the braking surface 465.

[0098] The process cartridge C having the driving force receiving part 46 / driving force receiving member 4 according to the present embodiment can more easily reach the position opposite to the braking surface 465 by combining with the flange part 47 during the installation process towards the image forming device.

[0099] [Example Four]

[0100] Figure 9 is a perspective view of a driving force receiving member according to an embodiment of the present application.

[0101] In this embodiment, the above-mentioned braking surface 465 is cancelled, as shown in the figure, the driving force receiving part 46 is only provided with a driving surface 464 and a guide surface 463, the guide surface 463 extends spirally upward from the base 43, after the processing cartridge C provided with the driving force receiving part 46 / driving force receiving member 4 is installed to the image forming device, the guide surface 463 can also play the same role as the braking surface 465 in relative to the shaft coupling part 204b / 208b of the braking force output member, thus, the structure of the driving force receiving part 46 is simplified, which is beneficial to improve the production efficiency of the driving force receiving part 46 and the driving force receiving member 4 provided with the driving force receiving part 46.

[0102] Further, the flange part 47 is arranged along the outer circumference of the center column 45, or in other words, the flange part 47 is formed by protruding radially outward from the outer circumferential surface of the center column 45, along the rotation axis L21, the flange part 47 is located at the free end 451 of the center column 45 (the end far away from the connecting part 41), when viewed along the direction perpendicular to the rotation axis L21, the driving force receiving part 46 does not coincide with the flange part 47, along the radial direction of the driving force receiving member 4, the protruding size of the flange part 47 does not exceed the size of the base 461 / driving surface 464 / guide surface 463, in the process of combining the driving force receiving member 4 with the force output member, the shaft coupling part 204b / 208b of the braking force output member hooks the flange part 47 to realize the combination of the driving force receiving member 4 and the force output member, which can effectively prevent the driving surface 464 of the driving force receiving member 4 from being separated 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 driving force from the force output member 203.

[0103] (Variation)

[0104] Figure 10 is a perspective view of a driving force receiving member according to an embodiment of the present application.

[0105] In this variation, along the rotation axis L21, relative to the free end of the center column 45, the flange part 47 is arranged towards the position close to the connecting part 41 (the position far away from the free end 451 of the center column), along the radial direction of the driving force receiving member 4, the protruding size of the flange part 47 does not exceed the size of the base 461 / driving surface 464 / guide surface 463.

[0106] As shown in Fig. 44 of the patent application in the background art, the force output member has a positioning column (positioning boss) 180i in the driving force output member 180 in addition to the driving force output member 180 and the braking force output member, when the driving force receiving member 4 is combined with the force output member, as shown in Fig. 51 of the patent application in the background art, the positioning column 180i in the force output member enters the positioning hole 452 of the center column 45, the flange portion 47 will gradually approach the braking force output member along with the driving force receiving portion 46 until the shaft coupling joint portions 204b / 208b hook the flange portion 47, thus, the flange portion 47 is arranged towards the position close to the connecting portion will make the shaft coupling joint portions 204b and the flange portion 47 can be combined more closely, and the driving surface 464 and the driving force output surface 180d can be more effectively prevented from being combined, so that the driving force receiving member 4 can more stably receive the driving force from the force output member.

[0107] [Embodiment five]

[0108] Figure 11 is a perspective view of the driving force receiving member involved in the embodiment five of the utility model; Figure 12A is a perspective view of the driving force receiving member involved in the embodiment five of the utility model starting to combine with the force output member; Figure 12B is a perspective view of the driving force receiving member involved in the embodiment five of the utility model after being combined with the force output member; Figure 12C is a side view of the driving force receiving member involved in the embodiment five of the utility model after being combined with the force output member, viewed in the direction perpendicular to the rotation axis of the driving force receiving member.

[0109] The driving force receiving member 4 in the embodiment is arranged such that at least a part of the combining portion 44 can move in the direction intersecting with the rotation axis L21, as shown in the figure, when viewed from the combining portion 44 towards the connecting portion 41 along the rotation axis L21 of the driving force receiving member, the driving force receiving member 4 can rotate around the rotation axis L21 in the direction r (clockwise direction), along the rotation direction r, the combining portion 44 is divided into a plurality of sub-combining portions spaced from each other.

[0110] The following is an example of a four sub-combination provided, in the direction of rotation r, the first sub-combination 4a, the second sub-combination 4b, the third sub-combination 4c and the fourth sub-combination 4d, wherein the first sub-combination 4a and the third sub-combination 4c are radially opposite, the second sub-combination 4b and the fourth sub-combination 4d are radially opposite, and at least one of the second sub-combination 4b and the fourth sub-combination 4d is provided to be movable relative to the first sub-combination 4a and the third sub-combination 4c, each sub-combination includes a portion of the center column 45; the first sub-combination 4a and the third sub-combination 4c can also be referred to as fixed combinations, and the second sub-combination 4b and the fourth sub-combination 4d can also be referred to as movable combinations, and the movable combination is movable relative to the fixed combination.

[0111] Preferably, the structure of the first sub-combination 4a and the structure of the third sub-combination 4c are the same, the structure of the second sub-combination 4b and the structure of the fourth sub-combination 4d are the same; the fixed combination and the movable combination are both extended from the connecting portion 41 / chassis 42 / base 43, wherein the movable combination is provided as a cantilever extended from the connecting portion 41 / chassis 42 / base 43, for example, in the radial direction of the driving force receiving member 4, the size of the connection between the movable combination and the connecting portion 41 / chassis 42 / base 43 is smaller than the size of the connection between the fixed combination and the connecting portion 41 / chassis 42 / base 43; more preferably, the fixed combination and the movable combination are both extended from the side of the base 43 away from the connecting portion 41.

[0112] The fixed combination includes a base plate 450, a base 461 and a protrusion 462, which are arranged in the radial direction perpendicular to the rotation axis L21 in turn and gradually away from the rotation axis L21, the base plate 450 is a part of the center column 45, the base 461 is provided with a guide surface 463, the protrusion 462 is provided with a driving surface 464, the driving surface 464 is located upstream of the guide surface 463 in the direction of rotation r, and the base 461 is also formed with an abutting surface 466 along the rotation axis L21; the movable combination includes a base plate 450, a flange portion 47 protruding radially outward from the free end 451 of the base plate 450 (the free end of the center column), and a pressing portion 48 provided on the base plate 450, the pressing portion 48 extends from the base plate 450 in a direction away from the rotation axis L21, and a pressing surface 481 is formed at the end away from the connecting portion 41.

[0113] Preferably, when viewed in a direction perpendicular to the rotation axis L21, the abutment surface 466 is substantially flush with the pressing surface 481 and perpendicular to the rotation axis L21, further, along the rotation axis L21, the abutment surface 466 and the pressing surface 481 are both separated from the free end 451 of the center column, or in other words, the abutment surface 466 and the pressing surface 481 are both closer to the connecting portion 41 than the free end 451 of the center column, and the pressing surface 481 and the free end 451 of the center column form a limiting space 482.

[0114] To more clearly show the coupling process of the driving force receiving member 4 and the force output member 180, the force output member 180 in the present embodiment and the following embodiments is cut off in part, so that the driving force output member 180 and the brake force output member 204 / 208 are exposed.

[0115] As shown in FIG. 4A, when the driving force receiving member 4 is gradually close to the force output member 180 along the rotation axis L21 with the process cartridge C, the guide surface 463 begins to abut against the inward protruding portion 208e of the second brake coupling member 208, and as the process cartridge C continues to be installed, the second brake coupling member 208 begins to be pushed away by the guide surface 463 in the rotation direction r, and thus the first brake coupling member 204 also moves in the rotation direction r, that is, the entire brake force output member gradually moves away from the driving force output member 180 in the rotation direction r, and at the same time, along the rotation axis L21, the upper protruding portion 204f and the lower protruding portion 180g are no longer opposite to each other and gradually staggered, and the entire brake force output member also retracts towards the cylindrical portion 180c / inside of the image forming apparatus (retracted state), so that the driving force output portion 180h is not driven to retract towards the cylindrical portion 180c / inside of the image forming apparatus together with the brake force output member 204 / 208. Figure 12A Figure 12B Figure 12C As shown in FIG. 4A, when the driving force receiving member 4 is gradually close to the force output member 180 along the rotation axis L21 with the process cartridge C, the guide surface 463 begins to abut against the inward protruding portion 208e of the second brake coupling member 208, and as the process cartridge C continues to be installed, the second brake coupling member 208 begins to be pushed away by the guide surface 463 in the rotation direction r, and thus the first brake coupling member 204 also moves in the rotation direction r, that is, the entire brake force output member gradually moves away from the driving force output member 180 in the rotation direction r, and at the same time, along the rotation axis L21, the upper protruding portion 204f and the lower protruding portion 180g are no longer opposite to each other and gradually staggered, and the entire brake force output member also retracts towards the cylindrical portion 180c / inside of the image forming apparatus (retracted state), so that the driving force output portion 180h is not driven to retract towards the cylindrical portion 180c / inside of the image forming apparatus together with the brake force output member 204 / 208.

[0116] As shown in FIG. 4A, when the driving force receiving member 4 is gradually close to the force output member 180 along the rotation axis L21 with the process cartridge C, the guide surface 463 begins to abut against the inward protruding portion 208e of the second brake coupling member 208, and as the process cartridge C continues to be installed, the second brake coupling member 208 begins to be pushed away by the guide surface 463 in the rotation direction r, and thus the first brake coupling member 204 also moves in the rotation direction r, that is, the entire brake force output member gradually moves away from the driving force output member 180 in the rotation direction r, and at the same time, along the rotation axis L21, the upper protruding portion 204f and the lower protruding portion 180g are no longer opposite to each other and gradually staggered, and the entire brake force output member also retracts towards the cylindrical portion 180c / inside of the image forming apparatus (retracted state), so that the driving force output portion 180h is not driven to retract towards the cylindrical portion 180c / inside of the image forming apparatus together with the brake force output member 204 / 208.

[0117] ​​It should be noted that, in the process of the driving force receiving member 4 and the force output member 203 combination, if the brake force output member (the second brake engagement member 204) is guided by the guide surface 463 and then passes the abutting surface 466 to reach the opposite side of the pressing surface 481, the brake force output member (the second brake engagement member 204) can still be kept in the retracted state, that is, the pressing surface 481 has the effect of preventing the brake force output member (the second brake engagement member 204) from stretching out from the retracted state to the initial state (the stretched out state).

[0118] In the embodiment, the brake force output member is kept in the retracted state, so that the brake force output member will not output the brake force to the driving force receiving member 4 during the working process of the process cartridge, and the friction between the brake force output member and the driving force receiving member during the process cartridge taking-out process can be reduced; further, in the process of the driving force receiving member 4 and the force output member 203 combination, the movable combination part is pressed by the brake force output member (the second brake engagement member 204) and deformed towards the direction close to the rotation axis L21 until the inward protruding part 208e passes the flange part 47 into the limiting space 482, then the movable combination part resets and the inward protruding part 208e is combined (clamped) with the flange part 47, so it can be seen that the movable combination part in the embodiment can swing relative to the fixed combination part between the direction close to the rotation axis L21 and the direction away from the rotation axis L21, and at the same time, the inward protruding part 208e also abuts against the abutting surface 466, so that the stable combination of the force output member 203 and the driving force receiving member 4 can be kept.

[0119] [Embodiment six]

[0120] Figure 13A is the perspective view of the driving force receiving member related to the embodiment six of the utility model; Figure 13B is the exploded schematic view of the driving force receiving member related to the embodiment six of the utility model.

[0121] The driving force receiving member 4 in the embodiment still comprises the fixed combination part and the movable combination part, and the difference from the embodiment five is that the movement mode of the movable combination part in the embodiment is set as sliding, specifically, the movable combination part can slide relative to the fixed combination part in the direction intersecting with the rotation axis L21, and preferably, the sliding direction of the movable combination part is perpendicular to the rotation axis L21.

[0122] As shown, further, the base 43 in the embodiment is also cut, that is, the fixed and movable joints in the embodiment also include a part of the base 43, for the convenience of description, the base in the fixed joint is referred to as the first base 43a, the base in the movable joint is referred to as the second base 43b, the base 461 and the protrusion 462 are both above the first base 43a (away from the connecting part 41), a part of the center column 45 extends upward from the second base 43b, the flange part 47 is located at the free end of the center column 45, the second base 43b is further provided with a guided part 431, the chassis 42 is provided with a guide part 421, through the cooperation of the guide part 421 and the guided part 431, the movable joint can slide in the direction intersecting the rotation axis L21; preferably, the guided part 431 is provided as a guided groove, the guide part 421 is provided as a guide protrusion, at least one of the guided groove 431 and the guide protrusion 421 is further provided with a limiting protrusion 422 limiting the movement of the movable joint towards the rotation axis L21.

[0123] In some embodiments, the positions of the guided groove and the guide protrusion can also be interchanged.

[0124] In some embodiments, the driving force receiving part 4 further includes an anti-disengagement part 4f for limiting the movement of the movable joint away from the rotation axis L21, the anti-disengagement part 4f and the limiting protrusion 422 jointly limit the movement range of the movable joint in the radial direction of the driving force receiving part 4, on the one hand, making the combination of the driving force receiving part 4 and the force output part 203 more stable, on the other hand, making the driving force receiving part 4 and the force output part 203 more easily disengage from the combination; as Figure 13B shown, the base 43 is provided with a mounting part 483 for engaging with the anti-disengagement part 4f, preferably, the anti-disengagement part 4f is an elastic member sleeved on the outer surface of the base 43, the mounting part 483 is a mounting groove provided on the base 43, the anti-disengagement part 4f is mounted in the mounting groove 483, when the movable joint is forced to move away from the rotation axis L21 by the acting force, the movable joint forces the elastic member to elastically deform, when the acting force is removed, the elastic member forces the movable joint to move towards the rotation axis L21.

[0125] In some embodiments, the driving force receiver 4 is further provided with a pushing member for pushing the movable engagement portion away from the rotation axis L21. When the driving force receiver 4 and the force output member 203 are engaged, under the pushing force of the pushing member, the flange portion 47 and the inward protrusion 208e of the second braking engagement mechanism can be engaged more tightly. When the processing box needs to be removed, as the driving force receiver 4 is pulled away from the force output member 203, the inward protrusion 208e squeezes the flange portion 47 to overcome the pushing force of the pushing member, and the movable engagement portion moves towards the rotation axis L21 until the inward protrusion 208e disengages from the flange portion 47. Subsequently, the pushing member again forces the movable engagement portion to move away from the rotation axis L21.

[0126] [Example 7]

[0127] Figure 14 Figure 15 is a perspective view of the driving force receiving device according to Embodiment 7 of this utility model; Figure 16 is a perspective view of the driving force receiving device according to Embodiment 7 of this utility model starting to be combined with the force output device. Figure 15B This is a perspective view of the combined driving force receiving component and force output component according to Embodiment 7 of this utility model; Figure 15C This is a side view of the drive force receiver and the force output component after they are combined, viewed along a direction perpendicular to the rotation axis of the drive force receiver, according to Embodiment 7 of this utility model.

[0128] like Figure 14 As shown, the connecting part 44 includes a central post 45, a base 461, and a protrusion 462. Along the radial direction perpendicular to the rotation axis L21 of the driving force receiving member, the central post 45, the base 461, and the protrusion 462 are successively away from the rotation axis L21. In this embodiment, the base 461 extends around the outer circumferential surface of the central post 45, that is, the central post 45 is surrounded by the base 461. Therefore, the base 461 can also be regarded as a pressing part, and the end face of the base 461 is the pressing surface 481. Along the rotation axis L21, the protrusion 462 extends further away from the connecting part 41 than the base 461, that is, the protrusion 462 extends beyond the pressing surface 481. At the same time, a driving surface 464 for receiving driving force is also formed on the protrusion 462.

[0129] Furthermore, the joint 44 also includes a flange 47 provided at the free end of the central column 45, and a limiting space 482 is formed between the flange 47 and the pressing surface 481 along the rotation axis L21.

[0130] like Figure 15A As shown, before the driving force receiving member 4 and the force output member 203 are combined, the driving force output part 180h and the braking force output member are separated along the rotation direction r. The connecting part 44 does not need to be provided with a guide surface for separating the braking force output member and the driving force output part 180h, and the structure of the connecting part 44 can be simplified.

[0131] In the process of the driving force receiving member 4 combining with the force output member 203, the brake force output member (the inward protruding part 208e of the second brake engagement mechanism) is first compressed to retract by the flange part 47, and as the process cartridge C is being installed, the inward protruding part 208e of the second brake engagement mechanism is pressed against the flange part 47 and finally goes over the flange part 47 into the limiting space 482, and at the same time, the brake force output member (the inward protruding part 208e of the second brake engagement mechanism) is compressed by the compression surface 481 and cannot extend, the inward protruding part 208e combines with the flange part 47, the lug 462 enters between the driving force output part 180h and the brake force output member, the driving force output surface 180d is opposite to the driving surface 464, the driving force receiving member 4 and the force output member 203 complete the combination, and as the driving force output member 180 starts to rotate in the direction indicated by r, the driving force output surface 180d outputs the driving force to the driving surface 464, the driving force receiving member 4 also rotates in the direction indicated by r, and the brake force output member will no longer output the brake force to the driving force receiving member 4.

[0134] In the embodiment, the combining part 44 is arranged to be movable relative to the connecting part 41 along the rotation axis L21, that is, the combining part 44 is movable between a position close to the connecting part 41 (combining part retracted state) and a position away from the connecting part 41 (combining part extended state).

[0135] As shown in the figure, the combining part 44 is formed separately from the base 43, and the driving force receiving member 4 further comprises a movable cavity 432 formed inside the base 43 and a retaining member 49 for retaining the combining part 44 in the position away from the connecting part 41, and the retaining member 49 is preferably arranged as a compression spring. The combining part 44 comprises a bottom plate 441, a central column 45 extending from one side of the bottom plate 441 and a driving force receiving part 46, and a driving force transmission part 442 extending from the other side of the bottom plate 441, along the rotation axis L21, the central column 45 and the driving force receiving part 46 extend in the direction away from the connecting part 41, and the driving force transmission part 442 extends in the direction close to the connecting part 41.

[0136] The driving force receiving part 46 is still provided with a guide surface 463 and a driving surface 464, wherein, in the combination process of the driving force receiving part 4 and the force output part 203, the guide surface 463 is used to force the brake force output part to rotate relative to the driving force output part 180h so as to separate the brake force output part and the driving force output part 180h from each other, and the driving surface 464 is used to receive the driving force. The driving force receiving part 46 in the embodiment is not provided with a brake surface for receiving the brake force.

[0137] The driving force transmission part 422 is used to combine with the base 43 to transmit the driving force received by the driving force receiving part 46 to the base 43, and further drive the rotating part 21 connected with the connecting part 41 to rotate. In some embodiments, the driving force transmission part 422 is provided as a protrusion extending from the bottom plate 441 to the direction close to the connecting part 41 along the rotating axis L21, and correspondingly, the side wall of the movable cavity 432 is provided with a groove 433 which can cooperate with the protrusion, or the positions of the protrusion and the groove are interchanged; the bottom disc 42 is formed as the bottom wall of the movable cavity 432, one end of the compression spring 49 abuts against the bottom disc 42, and the other end abuts against the side surface of the bottom plate 441 facing the connecting part 41.

[0138] Further, the combination part 44 further comprises a guide combination column 443 provided on the same side as the driving force transmission part 422, and correspondingly, the bottom disc 42 is provided with a guide hole 421 cooperating with the guide combination column 443, and the guide combination column 443 is provided as a cantilever which can be elastically deformed in the direction intersecting with the rotating axis L21, and the end of the cantilever is provided with a clamping protrusion 444, wherein, in the installation process of the combination part 44, the guide combination column 443 is pressed to be elastically deformed, and the clamping protrusion 444 is clamped with the guide hole 421; in the movement process of the combination part 44 along the rotating axis L21, the cooperation of the guide combination column 443 and the guide hole 421 can ensure that the movement track of the combination part 44 does not deviate.

[0139] When the driving force receiving part 4 combines with the force output part 203, the guide surface 463 forces the brake force output part to rotate in the rotating direction r to separate from the driving force output part 180h, and then the driving surface 464 is opposite to the driving force output surface 180d, the combination of the driving force receiving part 4 and the force output part 203 is completed, and the driving force receiving part 4 can receive the driving force output by the driving force output part 180h.

[0140] In the embodiment, the brake force output part is gradually retracted to the retracted state while being forced to rotate by the guide surface 463, and when the driving surface 464 is opposite to the driving force output surface 180d, the brake force output part can be in the state of being pressed by the guide surface 463 or in the extended state of not being pressed by the guide surface 463 and being extended, and no matter what state the brake force output part is in, it will not affect the driving force output surface 180d to output the driving force to the driving surface 464.

[0141] As described above, different from the above-mentioned embodiments, the coupling portion 44 in the present embodiment is arranged to be retractable, during the coupling of the driving force receiving member 4 and the force output member 230, the braking force output member is pressed by the guide surface 463, in turn, the guide surface 463 is pressed by the braking force output member 230, the coupling portion 44 will move towards the retracted state of the coupling portion, at the same time, the compression spring 49 will also be elastically deformed, thus, the driving force receiving portion 46 will be forced by the compression spring 49 towards the force output member 203, that is, along the rotation axis L21, the driving force receiving portion 46 is arranged to be movable along with the force output member / driving force output portion 180h / braking force output member, finally, the driving force receiving member 4 and the force output member 203 can also be kept in stable and close coupling.

[0143] Figure 18 is the exploded view of the driving force receiving member involved in the ninth embodiment of the present application; Figure 19A is the state diagram of the driving force receiving member in the process cartridge before the driving force receiving member and the force output member are coupled involved in the ninth embodiment of the present application; Figure 19B is the perspective view of the driving force receiving member before the driving force receiving member and the force output member are coupled involved in the ninth embodiment of the present application; Figure 20 is the state diagram of the driving force receiving member in the process cartridge after the driving force receiving member and the force output member are coupled involved in the ninth embodiment of the present application.

[0144] The coupling portion 44 in the eighth embodiment can move along with the driving force output portion 180h / braking force output member under the forcing of the compression spring 49 to ensure that the driving force receiving member 4 and the force output member 203 are kept in stable and close coupling, that is, the coupling portion 44 can actively move along with the driving force output portion 180h / braking force output member, the coupling portion 44 in the present embodiment will be arranged to passively move along with the driving force output portion 180h / braking force output member.

[0145] As shown in the figure, the retaining member 49 is preferably arranged as a tension spring, the tension spring 49 is used to keep the coupling portion 44 in the retracted state of the coupling portion. The driving force receiving member 4 further comprises an action rod 4e, the action rod 4e is movably installed on the driving end cover 300 / non-driving end cover 400 / first unit housing 1 / second unit housing 2, when receiving external force, the action rod 4e forces the coupling portion 44 to move from the retracted state towards the extended state.

[0146] The structure of the coupling portion 44 and the structure of the coupling of the coupling portion 44 and the base 43 are the same as those in the above-mentioned embodiments, here, the action rod 4e and its movement process will be mainly described.

[0147] The action lever 4e comprises an intermediate lever 4e1 and a force receiving portion 4e2 and a pushing portion 4e3 at two ends of the intermediate lever 4e1 respectively, the pushing portion 4e3 is provided in a fork shape, comprising two pushing levers 4e31 connected with the intermediate lever 4e1, at least one pushing lever 4e31 is provided with a pushing surface 4e32 inclined relative to the rotation axis L21, and a containing space 4e30 is formed between the two pushing levers 4e31.

[0148] Figure 19A An example in which the action lever 4e is mounted on the drive end cover 300 is shown, before the driving force receiving member 4 is combined with the force output member 203, the combination portion 44 is in a combination portion retracted state, the pushing surface 4e32 faces the surface of the bottom plate 441 on the side facing the connecting portion 41; as the force receiving portion 4e2 receives external force, the pushing surface 4e32 starts to push the bottom plate 441, and then the combination portion 44 gradually moves towards the combination portion extended state, as shown in Figure 19B The guide surface 463 provided in the combination portion 44 forces the brake force output member to move away from the driving force output portion 180h in the rotation direction r, and then the driving surface 464 faces the driving force output surface 180d, under the pushing action of the pushing lever 4e31, the combination portion 44 and the force output member 203 can maintain a stable and close combined state.

[0149] Preferably, the driving force receiving member 4 further comprises a reset member (not shown) for forcing the action lever 4e to reset, for example, the reset member is a compression spring or a tension spring mounted between the action lever 4e and the process cartridge shell / end cover; as shown in Figure 20 The combination portion 44 is in the combination portion extended state, the reset member is elastically deformed, when the external force F applied to the force receiving portion 4e2 is removed, the reset member releases the reset force, the action lever 4e resets, and at the same time, the tension spring 49 pulls the combination portion 44 from the extended state to the retracted state.

[0150] In some embodiments, the external force can come from the door cover of the image forming device, during the closing of the door cover, the door cover applies force to the force receiving portion 4e2.

[0151] In some embodiments, the external force can also come from the inner wall of the imaging device. There is an imaging device provided with a drawer type accommodating part, and a processing box is installed in the drawer type accommodating part. When the processing box needs to be installed or taken out, the door cover is opened, the drawer type accommodating part is first lifted for a distance along with the opening of the door cover, and then is pulled out. After the processing box is installed or taken out, the drawer type accommodating part is pushed to a predetermined position towards the inside of the imaging device, and finally, in the process of closing the door cover, the drawer type accommodating part is lowered for a distance again. For such an imaging device, the external force can be generated by the mutual interference between the inner wall of the imaging device and the force receiving part 4e2 in the process of pushing the drawer type accommodating part towards the inside of the imaging device, or can be generated by the mutual interference between the inner wall of the imaging device and the force receiving part 4e2 in the process of lowering the drawer type accommodating part when closing the door cover.

[0154] The above describes an embodiment of applying driving force to the driving force receiving member 4 by the driving force output surface 180d provided in the driving force output part 180h, however, the braking force output member will also rotate along with the driving force output part 180h in the working process of the force output member 203, and thus the braking force output member can also serve as a component for applying driving force to the driving force receiving member 4. The following will describe an embodiment of transmitting driving force by the combination of the braking force output member and the driving force receiving member 4.

[0155] As Figure 21As shown, the driving force receiving part 46 still comprises a base part 461 and a protrusion 462 located radially outside the center column 45, wherein the protrusion 462 is further away from the rotation axis L21 than the base part 461, and the protrusion 462 is provided with a driving surface 464 for receiving the driving force, which driving surface 464 can be combined with both the first brake engagement mechanism 204 and the second brake engagement mechanism 208, and the embodiment will describe the combination of the driving surface 464 and the second brake engagement mechanism 208.

[0156] As described above, along the radial direction of the force output part 203, the second brake engagement mechanism 208 is located inside the first brake engagement mechanism 204, and preferably, along the rotation direction r, the driving surface 464 will be opposite to the second brake engagement mechanism 208.

[0157] As shown, along the rotation direction r, the second brake engagement mechanism 208 has an inner output surface 208f located downstream, which is arranged spirally upward relative to the rotation axis L21 in the direction opposite to the rotation direction r, and preferably, the driving surface 464 is arranged as a spiral surface matched with the inner output surface 208f.

[0158] As Figure 22A , Figure 22B , Figure 23A and Figure 23B As shown, in order to more clearly show the combination state of the second brake engagement mechanism 208 and the driving force receiving part 2, Figure 23B the driving force output part 180h and the first brake engagement mechanism 204 are hidden in

[0159] Before the driving force receiving part 4 is combined with the force output part 203, along the rotation direction r, the driving force output part 180h and the brake force output part are away from each other, and during the combination of the driving force receiving part 4 and the force output part 203, if the brake force output part abuts against the protrusion 462, the brake force output part will be compressed and retracted, and as the force output part 203 rotates, when the driving force output part 180h abuts against the brake force output part, the driving force output part 180h rotates along the direction indicated by r together with the brake force output part, until the protrusion 462 no longer abuts against the brake force output part and the driving force output part 180h, the brake force output part and the driving force output part 180h will be extended, as Figure 23B shown, the inner output surface 208f abuts against the driving surface 464, the second brake engagement mechanism 208 starts to output the driving force to the driving force receiving part 4, and the brake force output part will no longer apply the brake force to the driving force receiving part.

[0160] As Figure 24As shown, before the driving force receiver 4 and the force output member 203 are engaged, the driving force output part 180h and the braking force output member approach each other along the rotation direction r. With the installation of the processing box C, the protrusion 462 presses the driving force output part 180h and / or the braking force output member, and the driving force output part 180h and / or the braking force output member retracts. As the driving force output part 180h rotates, the driving force output part 180h will push the braking force output member to rotate together. When the driving force output part 180h and / or the braking force output member is no longer pressed by the protrusion 462, the driving force output part 180h and / or the braking force output member extends. Subsequently, the inner output surface 208f abuts against the driving surface 464, the second braking engagement mechanism 208 begins to output driving force to the driving force receiver 4, and the braking force output member will no longer apply braking force to the driving force receiver.

[0161] Furthermore, the base 461 is also provided with a retaining surface 4611. Along the rotation axis L21, the retaining surface 4611 faces the connecting part 41. In 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 mechanism abuts against the retaining surface 4611, and the braking force output member can be held in a stable and tight engagement with the driving force receiving member 4.

[0162] [Example 11]

[0163] Figure 25 This is a perspective view of the driving force receiving device according to Embodiment Eleven of this utility model; Figure 26A This is a perspective view of the driving force receiving component and the driving force output component combined according to Embodiment Eleven of this utility model; Figure 26B This is a side view of the drive force receiving device and drive force output device after they are combined, viewed in a direction perpendicular to the rotation axis of the drive force receiving device, according to Embodiment Eleven of this utility model.

[0164] Unlike Embodiment 10, in this embodiment, the driving force receiving member 4 is driven by the first braking engagement mechanism 204 along the rotation direction r. The first braking engagement mechanism 204 has an external output surface 204g located downstream, which is also configured to extend spirally upward in the opposite direction to the rotation direction r.

[0165] like Figure 25 As shown, the driving force receiving part 46 in this embodiment includes a base 461 and a protrusion 462 located radially outside the central column 45. The protrusion 462 is further away from the rotation axis L21 than the base 461. A driving surface 464 that can cooperate with the external output surface 204g is provided on the protrusion 462. Along the radial direction perpendicular to the rotation axis L21, a clearance part 468 is also formed between the driving surface 464 and the central column 45.

[0166] As Figure 26A shown, the first brake engagement mechanism 204 is hidden in the figure for more clearly showing the function of the avoiding portion 468. The combination process of the combination portion 44 / the driving force receiving member 4 and the force output member 203 in the present embodiment is the same as that of the tenth embodiment, and will not be described herein again. However, when the driving force receiving member 4 and the force output member 203 are combined, the second brake engagement mechanism 208 enters the avoiding portion 468, as shown in Figure 26B the figure. The outer output surface 204g and the driving surface 464 abut against each other, the second brake engagement mechanism 208 starts to output the driving force to the driving force receiving member 4, and the brake force output member will no longer apply the brake force to the driving force receiving member.

[0167] Preferably, the base portion 461 in the present embodiment can also be provided with the above-mentioned retaining surface 4611. When the outer output surface 204g and the driving surface 464 abut against each other, the inner protruding portion 208e of the second brake engagement mechanism 208 entering the avoiding portion 468 also combines with the retaining surface 4611. Thus, the brake force output member can be kept in a state of being stably and closely combined with the driving force receiving member 4.

[0168] Optionally, when the retaining surface 4611 is not provided in the combination portion 44, the base portion 461 can also be omitted, and the structure of the combination portion 44 can be simplified.
