[0044] In order to make the purpose, technical scheme and technical effect of the embodiment of the present invention clearer, the technical scheme of the processing box of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is only a preferred embodiment of the present invention, not all embodiments. Based on the embodiment of the present invention, other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present invention.

[0045] Example 1

[0046] like Figure 1 , which is a schematic diagram of the structure of the process box 1 in Embodiment 1 of the present invention. The process box 1 comprises: a housing 2, in which a developer is stored; a first side wall 3 and a second side wall 4, which are arranged at both side ends of the process box 1 along the longitudinal direction of the process box 1; a developing roller 5, which is rotatably supported between the first side wall 3 and the second side wall 4; and a driving assembly 6, which is arranged on the first side wall 3, receives a driving force from the image forming device and drives the developing roller 5 to rotate.

[0047] like Figure 2 and Figure 3 , which is a schematic diagram and a cross-sectional view of the exploded structure of the driving assembly 6. The driving assembly 6 includes a power receiving assembly 8, a retaining component 9, a flange component 7, and a limiting component 10. The power receiving assembly 8 can receive the driving force of the image forming device and rotate. The flange component 7 can be operably connected to the power receiving assembly 8 to receive the driving force transmitted by the power receiving assembly 8 and rotate. The flange component 7 drives the developing roller 5 (see FIG. 1 ) through a gear train (not shown in the figure). Figure 1) rotate. The power receiving kit 8 includes a main body 11, and the main body 11 can rotate around its own axis X1. For the convenience of description, the rotation axis X1 of the main body 11 is called the rotation axis of the power receiving kit 8. The main body 11 has a first end connected to the flange member 7, and a coupling groove 11b and a power transmission part 11c are formed on the first end. The limiting component 10 is clamped on the coupling groove 11b to prevent the power receiving kit 8 from escaping from the flange member 7. In this embodiment, the limiting component 10 is specifically constructed as a retaining spring; the power transmission part 11c is a protruding block protruding in the radial direction of the main body 11, and cooperates with the force receiving part (not shown in the figure) provided in the flange member 7 to transmit the driving force to the flange member 7. There is also a second end on the main body 11 opposite to the first end, and a mounting groove 11a is formed on the second end. The power receiving claw 12 and the control part 13 of the power receiving claw 12 are installed in the mounting groove 11a together. Specifically, a first protrusion 11d is formed in the mounting groove 11a, and a second protrusion 13b is formed on the control part 13 of the power receiving claw 12. One end of the elastic member 14 is engaged with the first protrusion 11d, and the other end is engaged with the second protrusion 13b. Therefore, the control part 13 of the power receiving claw 12 is elastically connected in the mounting groove 11a and can be extended and retracted along the axis X1. In this embodiment, the elastic member 14 is specifically constructed as a compression spring. The power receiving claws 12 are arranged in a pair and are symmetrical about the axis X1. The pair of power receiving claws 12 are both provided with a guide slide 12a. The control portion 13 of the power receiving claw 12 is similar to an arch bridge shape, and a pair of through holes 13a1, 13a2 are arranged on one side thereof. An opening 13c is formed between the pair of through holes 13a1, 13a2. The connecting pin 15 passes through the through hole 13a1, the guide slide 12a and the through hole 13a2 in sequence to install the power receiving claw 12 in the opening 13c of the control portion 13. When the control portion 13 of the power receiving claw 12 telescopically moves along the axis X1 due to the elastic force of the elastic component 14, the connecting pin 15 can move along the guide slide 12a of the power receiving claw 12, thereby driving the power receiving claw 12 to move in the mounting groove 11a. The specific process will be described in detail later.

[0048] like Figure 2As shown, the main body 11 of the power receiving kit 8 is also formed with a positioning portion 11e on the first end, and the positioning portion 11e is a cylindrical protruding block extending radially along the main body 11, and the retaining component 9 is arranged between the positioning portion 11e and the power transmission portion 11c. The retaining component 9 is mounted on the processing box housing 2 near the bracket (not shown in the figure) of the power receiving kit 8 to limit rotation. Specifically, the bracket is provided with a protrusion that can be inserted into the retaining component 9 to prevent the retaining component 9 from rotating with the power receiving kit 8. The retaining component 9 includes a cylindrical protrusion 9a and an adjusting component 16, and the adjusting component 16 is mounted on the cylindrical protrusion 9a. In this embodiment, the cylindrical protrusion 9a and the adjusting component 16 are specifically set to two. The adjusting component 16 is specifically constructed as a pair of torsion spring structures, one end 16a1 of which abuts on the regulated portion 11f of the main body 11, and the other end 16a2 abuts on the inner surface of the retaining component 9. The cross-sectional shape of the regulated portion 11f of the main body 11 is approximately elliptical, and due to the elastic force of the regulating member 16, the short side portion of the elliptical cross-sectional shape of the regulated portion 11f is clamped in the regulating member 16, thereby limiting the installation posture of the power receiving claw 12 by limiting the stop position of the main body 11. In this embodiment, the retaining member 9 defines the installation posture of the power receiving claw 12 as follows, and the penetration direction S of the opening formed between the power receiving claws 12 faces the drive head in the image forming device, that is, the retaining member 9 can keep the penetration direction S of the opening formed between the power receiving claws 12 always maintained at a predetermined angle.

[0049] like Figure 4, which is a schematic diagram of the structure of the power receiving claw 12 cooperating with the mounting groove 11a of the main body 11. A limiting portion 11a1 is formed on the mounting groove 11a of the main body 11, and a limited portion 12b is formed on the power receiving claw 12. The limiting portion 11a1 cooperates with the limited portion 12b to limit the movement of the power receiving claw 12 in the mounting groove 11a along the opening 13c of the control portion 13 in the direction of the axis X1. When the elastic force of the elastic member 14 pushes the control part 13 upward, the connecting pin 15 is in the first position in the guide sliding part 12a of the power receiving claw 12, and the power receiving claw 12 is in the first position. Specifically, the first position is the position where the connecting pin 15 is at the bottom of the guide sliding part 12a. At this time, the power receiving claw 12 is in a relatively outer position in a direction perpendicular to the axis X1; when the control part 13 is pressed by external force, the guide sliding part 12a of the power receiving claw 12 slides along the connecting pin 15 in the control part 13. Since the limiting part 11a1 of the mounting groove 11a limits the movement of the limited part 12b of the power receiving claw 12 along the axis X1 direction, the power receiving claw 12 can only move in a direction perpendicular to the axis X1. At this time, the power receiving claw 12 is in the second position. Specifically, the second position is the position where the connecting pin 15 is at the top of the guide sliding part 12a. At this time, the power receiving claw 12 is in a relatively inner position in a direction perpendicular to the axis X1. That is to say, the power receiving claw 12 can move between a first position relatively outside in a direction perpendicular to the axis X1 and a second position relatively inside in a direction perpendicular to the axis X1. For the convenience of description, the first position is called an open position and the second position is called a closed position.

[0050] Combine the following Figure 2 , Figure 5 , Figure 7 and Figure 8 The process of the drive assembly 6 engaging with the drive head 100 of the image forming device when the processing box 1 is installed in the image forming device is specifically described. The drive head 100 has a bottom end column 101 and a pair of power output arms 102, and the drive head 100 is driven by the motor in the image forming device to rotate. When the drive assembly 6 moves toward the drive head 100 along the installation direction M, the retaining component 9 on the drive assembly 6 causes the power receiving kit 8 to rotate and causes the through direction S of the opening formed between the power receiving claws 12 to face the drive head 100. Since the power receiving claws 12 are in the open position, this open position is set so that the distance between the pair of power receiving claws 12 is greater than the distance between the pair of power output arms 102 of the drive head 100, thereby avoiding interference between the power receiving claws 12 and the power output arms 102 of the drive head 100.

[0051] As the drive assembly 6 is further installed, the bottom end column 101 of the drive head 100 abuts against the control part 13 and applies a pressure F to the control part 13. The control part 13 overcomes the elastic force of the elastic component 14 and retracts inward near one side of the flange component 7. During the inward retraction of the control part 13, the connecting pin 15 moves from the bottom end to the top end of the guide sliding part 12a of the power receiving claw 12, and the power receiving claw 12 moves from the open position to the closed position. When the power receiving claw 12 is in the closed position, the power receiving claw 12 can engage with the power output arm 102 of the drive head 100 to receive the driving force of the drive head 100.

[0052] Combine the following Figure 2 , Figure 6 , Figure 7 and Figure 8 The process of disengaging the drive assembly 6 from the drive head 100 of the image forming device when the processing box 1 is removed from the image forming device is specifically described. When the processing box is taken out from the image forming device, the bottom end column 101 of the drive head 100 no longer presses the control part 13 of the power receiving claw 12, so the elastic component 14 recovers its elastic deformation and extends the control part 13 from the retracted position. The control part 13 causes the power receiving claw 12 to move from the closed position to the open position during the extension process. At this time, the power receiving claw 12 disengages the power output arm 102 of the drive head 100, and the retaining component 9 causes the power receiving kit 8 to rotate and causes the penetration direction S of the opening formed between the power receiving claws 12 to face the drive head 100, so that the processing box 1 can be smoothly taken out of the image forming device.

[0053] In this embodiment, the limiting portion for limiting the movement of the power receiving claw 12 in the axial direction is specifically arranged on the main body of the driving component, which is only a preferred embodiment. Optionally, the limiting portion can also be arranged in the flange component 7, for example, two protrusions with snaps are extended from the flange component, and the protrusions are combined with the power receiving claw to limit the movement of the power receiving claw 12 in the axial direction.

[0054] Example 2

[0055] like Fig. 9 As shown, the difference between the embodiment 2 provided by the present invention and the embodiment 1 is that the control mechanism for controlling the movement of the power receiving claw in the embodiment 2 is different from that in the embodiment 1. The same parts in the embodiment 2 as those in the embodiment 1 are marked with the same reference numerals, and their descriptions will be omitted. In this embodiment, the processing box 1 includes a control rod 25, and the opening and closing of the power receiving claw in the driving assembly 601 can be controlled by moving the control rod 25.

[0056] like Fig.10As shown, similar to the embodiment 1, the power receiving kit 801 in the driving assembly 601 in this embodiment is also provided with an adjusted portion 1101f, and the adjusting component 16 cooperates with the adjusted portion 1101f to adjust the penetration direction of the opening between the power receiving claws to stay in a predetermined direction. In this embodiment, the retaining component 9 is installed in the power receiving kit 801 and is limited by the first retaining spring 1001, and the power receiving kit 801 passes through the flange member 7 and is limited by the second retaining spring 1002.

[0057] like Fig.11 As shown, the main body 1101 of the power receiving kit 801 in this embodiment has a hollow structure, and a core-pulling connecting rod mechanism is installed in the hollow structure. The core-pulling connecting rod structure has a core-pulling part 1102, a connecting rod 23, and a power receiving claw 1201 connected to the connecting rod 23. The top of the core-pulling part 1102 is provided with a first connecting rod hinge part 1102a, and the end of the connecting rod 23 close to the core-pulling part 1102 is provided with a core-pulling hinge part 23, and an axle pin (not shown in the figure) passes through the first connecting rod hinge part 1102a and the core-pulling hinge part 23 to connect the core-pulling part 1102 and the connecting rod 23. Specifically, the first connecting rod hinge part 1102a and the core-pulling hinge part 23 are both set as hole structures, and the core-pulling part 1102 and the connecting rod 23 remain hinged. A claw hinge 23b is provided on the side of the connecting rod 23 close to the power receiving claw 1201, and a second connecting rod hinge 1201b cooperating with the claw hinge 23b is provided on the power receiving claw 1201. An axle pin 22 passes through the second connecting rod hinge 1102a and the claw hinge 23 to connect the power receiving claw 1201 and the connecting rod 23. Specifically, the second connecting rod hinge 1102a and the claw hinge 23 are both configured as hole structures, and the power receiving claw 1201 and the connection 23 are also hinged. One end of the elastic member 20 abuts against the main body 1101, and the other end abuts against the core pulling part 1102, which is used to control the movement of the core pulling part 1102 in the axial direction of the main body 1101. A limiting axle pin mounting hole is arranged at one end of the main body 1101 close to the power receiving claw 1201, and a sliding groove 1201a is arranged on the power receiving claw 1201. A limiting axle pin 21 passes through the limiting axle pin mounting hole and the sliding groove 1201a. The sliding groove 1201a can slide along the limiting axle pin 21, and the limiting axle pin can limit the movement of the power receiving claw 1201 in the axial direction of the main body 1101. A through hole 1101b is also provided on the main body 1101 and penetrates the main body 1101b in the radial direction. A force-bearing component mounting hole 1102b is provided on the core-pulling part 1102. A force-bearing component 24 passes through the through hole 1101b and the force-bearing component mounting hole 1102b. The length of the through hole 1101b in the axial direction of the main body 1101 is greater than the length of the force-bearing component 24. The force-bearing component 24 can bear force and drive the core-pulling part 1102 to move in the axial direction of the main body 1101.

[0058] like Fig.12 and Fig.13 The figures show schematic structural parts when the power receiving claw 1201 is in the open position and the closed position respectively. Fig.12 The force-bearing component 24 is in a state where there is no force on it. The elastic force of the elastic component 20 pushes the core-pulling part 1102 to move outward, and the core-pulling part 1102 pushes the power receiving claw 1201 to move through the connecting rod 23. Since the limiting shaft pin 21 limits the movement of the power receiving claw 1201 in the axial direction, the power receiving claw 1201 moves along a direction perpendicular to the axial direction of the main body 1101 under the push of the connecting rod 23, and when the limiting shaft pin 21 is located on the inner side of the sliding groove 1201a close to the axis, the power receiving claw 1201 stops moving, and at this time the power receiving claw is in the open position. Fig.13 When the force-bearing member 24 receives an inward force F1, it overcomes the elastic force of the elastic member 20 and drives the core-pulling part 1102 to move inward. At the same time, the core-pulling part 1102 drives the power receiving claw 1201 from the open position to the closed position through the connecting rod part 23. When the limit pin 21 is located on the outer side of the sliding groove 1201a away from the axis, the power receiving claw 1201 stops moving. The rotatable method of controlling the movement stroke of the power receiving claw 1201 can also be controlled by adjusting the length of the through hole 1101b in the axial direction. Specifically, the movement stroke of the force-bearing member 24 in the axial direction is adjusted by adjusting the length of the through hole 1101b in the axial direction, and finally the movement stroke of the power receiving claw 1201 is controlled.

[0059] like Fig.14 and Fig.15 As shown, the control mechanism for controlling the movement of the power receiving claw 1201 in this embodiment specifically includes a control rod 25 that can rotate around a fulcrum and a force transmission member 26 that contacts the force receiving member 24. In this embodiment, the flange member is configured to drive the photosensitive drum 30 in the process cartridge to rotate and is specifically arranged at an axial end of the photosensitive drum 30. When the process cartridge is not installed in the image forming device, the control rod 25 does not receive external force, and the power receiving claw 1201 is in a state as shown in FIG. Figure 4 When the process cartridge is installed into the image forming apparatus along the installation direction M, the opening of the power receiving claw 1201 is opened in the penetration direction S (see Figure 2) is still installed in a posture facing the drive head 100, and at this time, the power receiving claw 1201 is also in the open position, the process cartridge can be smoothly installed to the predetermined position, and then the machine door cover of the image forming device (not shown in the figure) is closed, and the control lever 25 is pressed by the machine door cover of the image forming device, so that the control lever rotates around the fulcrum 25a and presses the force transmission member 26, the force transmission member 26 transmits the received force to the force receiving member 24 and presses the force receiving member 24 to move inward, and the power receiving claw 1201 moves from the open position to the closed position and engages with the power output arm 102 of the drive head 100. When it is necessary to take out the process cartridge, the machine door cover of the image forming device is opened, the machine door cover releases the pressing of the control lever 25, the elastic member 20 pushes the core pulling part 1102 to move the power receiving claw 1201 from the closed position to the open position, and then the adjustment component 16 adjusts the penetration direction of the opening of the power receiving claw 1201 so that it can be taken out of the image forming device in a posture facing the drive head 100.

[0060] Example 3

[0061] Next, the embodiment 3 provided by the process cartridge of the present invention is described. The difference between the embodiment 3 and the embodiment 2 is only that the control mechanism for controlling the movement of the power receiving claw 1201 is different. The same parts in the embodiment 3 as those in the embodiment 2 are marked with the same reference numerals, and their description will be omitted.

[0062] like Fig.16 and Fig.17 As shown, the control mechanism of this embodiment includes a control rod 2501, a rotating cam 2601 connected to the control rod, and a conversion cam 2602. An elastic member 27 is arranged between the control rod 2501 and the processing box housing. One end of the elastic member 27 abuts against the control rod 2501, and the other end abuts against an abutment 28 arranged on the processing box housing. A hook 2501a is arranged at one end of the control rod 2501 close to the force-bearing member 24, and a bayonet 2601a that cooperates with the hook 2501a is arranged on the rotating cam 2601. The hook 2501a and the buckle 2601a are movably matched, and when the control rod 2501 moves, the rotating cam 2601 can be driven to rotate. The conversion cam 2602 is provided with an inclined surface 2602b, and the rotating cam 2601 is provided with an inclined surface pressing portion 2601b that can press the inclined surface 2602b, wherein the conversion cam 2602 is provided with a protruding piece 2602c, and the protruding piece 2602c is inserted into the holding member 9 (see Fig.10), and then a bracket (not shown) provided at the attachment of the power receiving kit is used to limit the rotation of the conversion cam 2602 and the retaining component 9. When the control rod 2501 is moved by an external force and drives the rotating cam 2601 to rotate, the rotating cam 2601 presses the inclined surface 2602b on the conversion cam 2602 through the inclined surface pressing portion 2601b, so that the conversion cam 2602 moves inward along the axis, and the conversion cam 2602 presses the force-bearing member 24 to drive the core-pulling portion 1102 to move inward along the axis.

[0063] like Fig.16 As shown, in this embodiment, when the processing box is not installed in the image forming device, the control rod 2501 slides to the left under the elastic force of the elastic member 27, which drives the rotating cam 2601 to rotate clockwise. At this time, the rotating cam 2601 does not press the conversion cam 2602, and the power receiving claw is in an open state. When the processing box is installed in the image forming device and the machine door cover is closed, the machine door cover presses the control rod 2501 and causes the control rod 27 to move to the right against the elastic force of the elastic member 27. While the control rod 2501 moves to the right, it drives the rotating cam 2601 to rotate counterclockwise. During the counterclockwise rotation, the rotating cam 2601 presses the conversion cam 2602 so that the rotating cam 2602 moves inward along the axis direction and finally drives the power receiving claw to the closed position. The process of removing the processing box is opposite to the process of installing the processing box, which will not be repeated here.

[0064] Example 4

[0065] Next, a description will be given of Embodiment 4 provided by the process cartridge of the present invention. Embodiment 4 differs from Embodiment 2 only in the control mechanism for controlling the movement of the power receiving claw 1201.

[0066] like Fig.18 and Fig.19 As shown, the control mechanism used in this embodiment is an electromagnetic structure, and the control mechanism includes an electromagnet 40, and the electromagnet 40 has an electromagnetic head 40a. The side end of the core-pulling part 1102 close to the electromagnetic head 40a is magnetic, and one end of the wire 40b connected to the electromagnet 40 is connected to the electromagnet 40, and the other end is connected to the battery (not shown in the figure) set on the processing box. Before the processing box of this embodiment is installed in the image forming device, a magnetic repulsive force is formed between the electromagnetic head 40a of the electromagnet 40 and the core-pulling part 1102, so that the power receiving claw 1201 is in an open position. When the processing box is installed in a predetermined position in the image forming device, the machine door cover of the image forming device is closed, and the machine door cover presses and triggers the electrical switch (not shown in the figure) set on the processing to form a magnetic attraction between the electromagnetic head 40a and the core-pulling part 1102, and the power receiving claw 1201 moves from the open position to the closed position to engage with the drive head of the image forming device. The process of removing the processing box is opposite to the process of installing the processing box, which will not be repeated here.

[0067] The present invention provides a new driving assembly and a processing box, wherein the driving assembly enables the processing box to be smoothly installed in and removed from an image forming device through the translation of a power receiving claw, and the power receiving claw does not interfere with the driving head of the image forming device, has a simple structure, and has stable power transmission. The technical problem in the prior art that the power receiving part may be stuck during the deflection process due to repeated deflection and cannot be normally engaged with the driving head of the image forming device is solved.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
