A process cartridge according to an aspect of the present application includes a driving assembly detachably mounted in an image forming apparatus to receive a driving force, the driving assembly including: a power receiving port and a hub; the power receiving opening receives driving force from the image forming apparatus and transmits the driving force to the hub, the power receiving opening is further provided with a pair of claws, and the image forming apparatus is different from the related art in that: the driving assembly further comprises a control mechanism, and the control mechanism can control the clamping jaws on the power receiving openings to be in preset positions. The predetermined position is an avoidance position, and the claw at the predetermined position can avoid interference in the process of loading and unloading the processing box. The predetermined position may be that the driving assembly is mounted into the image forming apparatus in a mounting direction, and the control mechanism controls one of the claws on the power receiving port to be positioned above the other claw as viewed in the mounting direction.
Specifically, the driving assembly can be detachably matched with a driving part arranged in the image forming device in an indirect or direct mode to receive driving force, the clamping jaw is used for being clamped with the driving part and can be driven by the driving part to rotate, the power receiving port can transmit the driving force received from the driving part to the hub,
the control mechanism is capable of controlling a pair of the jaws to be in a predetermined position to avoid the driving member in the mounting direction.
The control mechanism can adopt two control modes:
the first mode is as follows: the control mechanism can stop the pair of jaws at the predetermined position after the power receiving port loses the driving force from the driving member. This is used for examples four to seven and examples nine to eleven.
In order to further improve the avoidance effect, the power receiving port may be moved in a direction away from the driving member in the axial direction to a disengaged state from the driving member after the pawl is stopped at the predetermined position. This action can be automatically achieved in the process of mounting and dismounting the process cartridge by the structural design, such as the seventh embodiment and the eleventh embodiment; the control mechanism may be operated by applying an external force thereto, as in the ninth and tenth embodiments.
The second mode is as follows: after the driving part stops driving the power receiving port to rotate, external force is directly applied to the control mechanism and the control mechanism acts, and therefore the pair of clamping jaws rotate to the preset position. This is true for all of examples one to three and example eight.
Similarly, in order to improve the avoidance effect, the control mechanism can also move the power receiving port in the direction away from the driving component along the axial direction under the action of external force through structural improvement, such as the first to third embodiments.
On the basis of this, in order to facilitate the application of external force to the control mechanism, a transmission mechanism connected to the control mechanism will be described in some embodiments.
The technical solution of the present application is described in detail by examples below.
Example one
Fig. 1 is a perspective view of a process cartridge 10 according to the present application, in which a power receiving port 11 for receiving rotational power from an image forming apparatus is provided at a longitudinal end of the process cartridge 10.
The following describes in detail how to realize the control of the power receiving port by the control mechanism to be engaged with the driving mechanism in the image forming apparatus to transmit power by using the solution of the present application.
Fig. 2 is a partial structural view of the present embodiment. A hub 13 is arranged at the longitudinal end part of the processing box, a locating ring 14 is coaxially arranged on the hub, and the power receiving port 11 penetrates through the locating ring 14 and is arranged on the hub 13. When the process cartridge is mounted in the image forming apparatus, the power receiving port 11 is engaged with a driving mechanism 100 in the image forming apparatus to transmit power. The hub 13 can be directly connected with a rotating part of the processing box, for example, connected with the photosensitive element 12, and the photosensitive element 12 is driven to rotate after receiving power from the image forming device through the power receiving port 11; the hub 13 is provided with a gear 130 on the outer circumference thereof, and the gear 130 transmits the rotational power to other rotating components of the process cartridge 10. The hub 13 may be configured to engage with another transmission gear on the image forming apparatus, and transmit the rotational power to the rotational member of the process cartridge 10 through the transmission gear.
Fig. 3 is a view showing a state in which the power receiving port 11 is engaged with the driving mechanism 100 in a process in which the process cartridge 10 is mounted into the image forming apparatus.
Fig. 4 is a view showing a relative positional state of the power receiving port 11 and the driving mechanism 100 during the process of mounting the process cartridge 10 into the image forming apparatus.
A pair of jaws 111 are symmetrically arranged on one free end part of the power receiving port 11, and a space 112 is arranged between the jaws; one free end part of the driving mechanism 100 is 102, a pair of symmetrically arranged bulges 101 are arranged on the driving mechanism and used for being engaged with a claw 111 arranged at the free end part of the power receiving port 11, when the power receiving port 11 is engaged with the driving mechanism 100, the free end part 102 is positioned in a space 112, and the driving mechanism 100 is driven by a motor arranged in the image forming device and can drive the power receiving port 11 to rotate.
As shown in fig. 3, the depth of engagement between the pawl 111 on the power receiving port 11 and the driving mechanism protrusion 101 is H1. When the process cartridge 10 is mounted in the image forming apparatus in the direction of arrow X shown in fig. 4, the power receiving port pawl 111 is positioned opposite to the projection 101 of the driving mechanism 100, and interference occurs, so that the process cartridge 10 cannot be mounted smoothly.
Therefore, in order to solve this problem, it is necessary to retract the power receiving port 11 in the direction of the rotation axis (Y direction in fig. 4) thereof by a distance, or at least by a distance H1, by a control mechanism before or during the mounting of the process cartridge to the image forming apparatus, so that the pawl 111 of the power receiving port 11 is spaced from the projection 101 of the driving mechanism 100.
Fig. 5 is a schematic view of the pawl 111 on the power receiving port and the protrusion 101 on the driving mechanism being in an avoidance state after the power receiving port is retracted by a distance H1 along the Y direction.
As shown in fig. 5, the height of the pawl 111 is H2, the height of the free end 102 of the driving mechanism 100 is H3, H3 is the distance from the end surface of the free end of the driving mechanism 100 to the portion of the protrusion 101 closest to the end surface, and when the H2 is greater than or equal to the H3, the power receiving port 11 is allowed to descend by the minimum height of H1. Of course, the control mechanism lowers the power receiving port 11 by at least HI plus H3, which is the most ideal situation, so that the power receiving port 11 and the driving mechanism 100 can completely avoid each other, and interference in mounting the process cartridge can be prevented.
However, since the image forming apparatuses are different in model, there is a difference in the internal structure of the apparatuses, and it is directly impossible to lower the power receiving port 11 by a sufficient height to achieve avoidance interference. Therefore, according to the technical scheme provided by the application, under the condition that the process cartridge is in the most limited state, namely when the allowed descending stroke of the power receiving port 11 is only H1, the problem that the power receiving port 11 does not interfere with the driving mechanism in the process of mounting the process cartridge can be solved, and the aims of smoothly mounting the process cartridge 10 and smoothly meshing the power receiving port and the driving mechanism are fulfilled.
The technical scheme provided by the application is that after ensuring that the power receiving port 11 descends by at least the height of H1, the power receiving port 11 is controlled by the control mechanism to rotate, so that in the process of installing the processing box into the image forming device along the direction X shown in the figure, the space 112 between the pair of symmetrical clamping jaws 111 on the power receiving port 11 faces the free end part 102 of the driving mechanism 100, as shown in FIG. 6, even if the central connecting line of the pair of symmetrical clamping jaws 111 of the power receiving port 11, which is perpendicular to the rotation axis of the power receiving port 11, is perpendicular to the installation direction X of the processing box. Fig. 7 shows a sectional view taken along the direction of the mounting direction X of the process cartridge, the space 112 between the claw portions 111 of the inlet 11 being capable of allowing the free end portion 102 of the driving mechanism to pass through.
When the process cartridge 10 enters the image forming apparatus and is mounted in place, the force applied to the power receiving port 11 by the control mechanism is cancelled, the power receiving port 11 extends in the direction of the rotation axis thereof toward the driving mechanism 100, and the pawl 111 engages with the projection 101 to transmit power after the image forming apparatus is started.
How the control mechanism provided by the present application enables the power receiving port to achieve telescopic and rotary motions will be further described below in conjunction with the structure of the control mechanism.
Fig. 8 is an exploded view of an embodiment of a control mechanism and a power receiving port provided in this embodiment.
The control mechanism of the present embodiment includes a hub 13, a retainer ring 14, a guide bush 15, and an adjustment member 16. The hub 13 has a hollow portion 131 with an opening therein, and the guide bush 15 and the adjustment member 16 are installed in the hollow portion 131 through the opening. The power receiving opening 11 is arranged along the axial direction of the hub 13 through the guide sleeve 15 and the adjusting component 16. The positioning ring 14 is matched with the guide sleeve 15 and arranged at the opening of the hub 13 along the axial direction of the hub 13.
The present embodiment also provides an elastic element 17, which is arranged inside the hub 13 in the axial direction of the hub 13; an end cap 103 for fixedly fitting to a longitudinal end portion of the process cartridge and for passing a free end portion of the power receiving port 11 therethrough; the end cap 103 is used for supporting the hub 13.
Fig. 9 is a partially exploded view for explaining an embodiment of the present application.
As shown in fig. 9, a through hole 143 is formed in the middle of the retainer ring 14 for allowing the power receiving port 11 to pass through. The inner circumference of the positioning ring 14 is provided with a first boss 141; meanwhile, a through hole is formed in the middle of the guide sleeve 15 and used for allowing the power receiving port 11 to penetrate through, a second boss 151 is further arranged on the guide sleeve 15, and the surface of the second boss 151 is an inclined surface 1511; the retainer ring 14 is further provided with an acted part 144 for receiving external acting force. After assembly, the retainer ring 14 is supported by the guide sleeve 15, and the first boss 141 on the retainer ring 14 is supported by the upper surface 152 of the guide sleeve 15; a clamping block 1031 is further arranged on the end cover 103, and a blocking part 153 is further arranged on the upper surface of the guide sleeve 15; after assembly, the latch 1031 on the end cap 103 engages the stop 153 on the guide sleeve 15, as shown in fig. 10.
Since the end cap 103 is fixedly mounted on the process cartridge, the latching members 1031 on the end cap 103 cooperate with the blocking portions 153 on the guide sleeve 15 to prevent the guide sleeve 15 from rotating about its rotation axis. Therefore, when an external force acts on the positioning ring 14 and causes the positioning ring to rotate, the guide sleeve 15 does not rotate relative to the end cover 103.
Fig. 11 and 12 are schematic views showing the cage 14 receiving an external force.
As shown in fig. 11, when an external force F acts on the acted-on portion 144 of the positioning ring 14 in the direction shown in the drawing and the positioning ring 14 rotates in the direction shown in the drawing W around the rotation axis thereof, the first boss 141 provided in the inner circumferential direction of the positioning ring 14 rotates with respect to the upper surface 152 of the guide sleeve 15.
As shown in fig. 12, after the retainer ring 14 rotates, the first boss 141 abuts against the second boss 151 of the guide sleeve 15, and the guide sleeve 15 slides in the Y direction shown in the figure by forcibly pushing the inclined surface 1511 of the second boss 151. A clamp spring 18 is arranged on the outer circumference of the main body 113 of the power receiving port 11, and the clamp spring 18 protrudes outside the main body 113 of the power receiving port 11 along the radial direction and is abutted against the lower bottom surface of the guide sleeve 15; when the guide sleeve 15 slides along the Y direction by the positioning ring 14, the guide sleeve 15 slides along the Y direction by the power receiving port 11 through the snap spring 18. Meanwhile, the sliding stroke of the power receiving port 11 along the Y direction can be controlled by a height difference H4 formed by the inclined surface 1511 along the axial direction of the guide sleeve 15, wherein the height difference H4 is the distance from the upper surface 152 of the guide sleeve 15 to the top of the second boss 151 and is greater than or equal to H1, so as to ensure that the sliding stroke of the power receiving port 11 along the rotation axial direction thereof is at least H1.
As shown in fig. 9, the control mechanism further includes an adjustment member 16. The lower end of the positioning ring 14 is provided with a first engaging portion 142, the first engaging portion 142 includes a first toothed portion 1421 and a second toothed portion 1422, and a plane 145 is arranged between the first toothed portion 1421 and the second toothed portion 1422; the upper end of the adjusting component 16 is provided with a second engaging portion 161, the second engaging portion 161 includes a third toothed portion 1611 and a fourth toothed portion 1612, and a plane 162 is disposed between the third toothed portion 1611 and the fourth toothed portion 1612. The first engaging portion 142 and the second engaging portion 161 are engaged with each other when the control mechanism is assembled. When the positioning ring 14 is rotated by an external force, the positioning ring 14 and the adjusting component 16 are engaged with each other, that is, when the positioning ring 14 is rotated, the adjusting component 16 is rotated.
Fig. 13 is a structural view of the hub 13. The interior of the hub 13 is a hollow part 131, and a pair of first force-bearing columns 134 symmetrically arranged along the inner circumferential direction of the hub and a pair of second force-bearing columns 135 symmetrically arranged are distributed on the inner circumference of the hub; a pair of symmetrically arranged first gaps 132 and a pair of symmetrically arranged second gaps 133 are arranged between the first force bearing column 134 and the second force bearing column 135.
Fig. 14 is a schematic view of the assembly between the hub 13 and the adjustment member 16. As shown in fig. 13, the adjusting member 163 is provided with a stud 163 in an outer circumferential direction, the stud 163 has a side surface 1631 and an inclined surface 1632; a side face of the first force-bearing column 134 arranged in the inner circumferential direction of the hub 13 is an inclined face 1341, the second force-bearing column 135 is provided with a side face 1351, and the first gap 132 is arranged between the inclined face 1341 and the side face 1351; the other side of the first force-bearing column is 1342, the other side of the second force-bearing column is 1352, and the second gap 133 is disposed between the side 1342 and the side 1352.
When the adjustment member 16 is assembled into the hub 13, a pair of symmetrically disposed studs 163 of the adjustment member 16 are placed in the first gap 132, a side surface 1631 of the stud 163 is opposite to the side surface 1351 of the second force-receiving stud 135, and an inclined surface 1632 on the other side of the stud 163 is opposite to the inclined surface 1341 on the one side of the first force-receiving stud 134.
The first engaging portion 142 of the positioning ring 14 engages with the second engaging portion 161 of the adjusting member 162, and when the positioning ring 14 is rotated by an external force, the positioning ring 14 drives the adjusting member 16 to rotate; side 1631 now engages side 1351 on hub 13 and drives the hub to rotate; meanwhile, a transmission pin 19 is arranged to penetrate through the body 113 of the power receiving port 11 in the radial direction, and when the power receiving port 11 is assembled, the two free end portions of the transmission pin 19 are arranged in the second gap 133, and when the hub 13 is driven, the power receiving port 11 is driven to rotate under the action of the transmission pin 19.
Therefore, through the technical scheme provided by the application, the power receiving port can rotate around the rotation axis of the power receiving port, and the power can slide along the rotation axis direction. Further, the present application provides a control mechanism that performs an operation of controlling rotation and sliding of the power receiving port.
After the processing box is installed in place, the power receiving port 11 is meshed with a driving mechanism 100 in the image forming device, the driving mechanism 100 drives the power receiving port 11 to rotate around the W direction, and then a transmission pin 19 arranged on the power receiving port 11 drives the hub 13 to rotate; after the hub 13 rotates in the direction W, the inclined surface 1341 formed on the inner circumference of the hub 13 abuts against the inclined surface 1632 formed on the outer circumference of the adjusting member 16, and the axial component force generated when the inclined surfaces abut against each other disengages the engaging portions 161 and 142 between the adjusting member 16 and the retainer ring 14, so that the adjusting member 16 and the retainer ring 14 rotate relatively. The gear part is arranged on the outer circumference of the hub, and the gear part can transmit the rotary power to other rotary parts in the processing box.
In the process of mounting the process cartridge, before the process cartridge is not completely mounted in place, the power receiving port is rotated by the control mechanism to the relative position shown in fig. 6 between the power receiving port 11 and the driving mechanism 103, even if the center line of the pair of mutually symmetrical claws 111 of the power receiving port 11 perpendicular to the rotation axis of the power receiving port 11 is perpendicular to the mounting direction X of the process cartridge, the space 112 between the claws 111 of the power receiving port 11 can allow the free end portion 102 of the driving mechanism to pass through. This situation is the most desirable one. However, the solution provided by the present application can achieve that the relative position between the jaw of the free end of the power receiving port 11 and the driving mechanism is within a certain range, and still achieve that the power receiving port 11 passes over the free end of the driving mechanism 100 and smoothly engages with the driving mechanism 100.
The following will describe how the power receiving port is controlled to pass over and engage the free end of the drive mechanism 100 during cartridge installation.
FIG. 15 is a partial structural view of the present embodiment, wherein FIG. A-A is a sectional view taken in a direction perpendicular to the rotational axis of the power receiving port.
As shown in fig. 15, the first engaging portion 142 is a portion of the lock ring 14, the second engaging portion 161 is a second engaging portion of the adjusting member 16, and the first engaging portion 142 and the second engaging portion 161 are engageable with each other to transmit power; the first engagement portion 142 includes a pair of engagement portions 142a and 142b symmetrical to each other when viewed in a cross-sectional view a-a; the second engagement portion 161 includes a pair of engagement portions 161a and 161b symmetrical to each other.
Fig. 16 is a schematic diagram showing a relative state of the bezel 14 and the adjustment member 16. In this embodiment, the relative positions of the pair of claws 111 on the power receiving port 11 and the pair of engaging portions 161a and 161b on the adjusting member 16 are set to be fixed, and the relative positions can be determined by the relative positions of the power receiving port 11 and the adjusting member 16 with the hub 13, and when the relative positions of the power receiving port 11 and the hub 13 are determined and the relative positions of the adjusting member 16 and the hub 13 are also determined, the relative positions of the pair of claws 111 on the power receiving port 11 and the pair of engaging portions 161a and 161b on the adjusting member 16 can be fixed.
The dimension of the outer periphery of the free end portion of the driving mechanism 100 of the image forming apparatus is set to d, and when the shortest distance between the pair of claws 111 of the power receiving port 11 is N1, that is, when N1 is d, the claws 111 of the power receiving port 11 can just avoid interfering with the free end portion 102 of the driving mechanism 100 during the process cartridge is mounted into the image forming apparatus, and the line connecting the positions of the second engaging portions 161a and 161b of the regulating member 16 is set to L1.
Fig. 17 shows that when the shortest distance between the jaws 111 on the power receiving port 11 is N1, and N1 is d, the adjusting member 16 and the power receiving port 11 are located at another position, the jaws 111 just can avoid interference with the free end 102 of the driving mechanism 100, and the connecting line between the engaging portions 161a and 161b is L2.
The angle between the connecting lines L1 and L2 of the engaging portions at two positions of the adjusting component shown in fig. 16 and 17 is related to the external dimension d of the free end 102 of the driving mechanism 100, when the claws 111 on the power receiving port 11 are not in the range of the angle, the power receiving port 11 is not interfered with the free end of the driving mechanism 100 when the processing box is installed, and when the claws 111 of the power receiving port 11 are in the range of the angle, the power receiving port 11 needs to be controlled by a control mechanism to rotate around the rotation axis thereof, so that the power receiving port 11 can avoid interference with the driving mechanism during the installation process.
When the jaws 111 of the power receiving port 11 are located within the range of the included angle, the power receiving port 11 is driven to rotate by a control mechanism, which is described below with reference to fig. 18 to 22.
When the shortest distance N between the jaws 111 is smaller than d, the power receiving port 11 will interfere with the driving mechanism 100 in the installation process; when the shortest distance N between the jaws 111 is greater than or equal to d, the power receiving port 11 will avoid interference with the driving mechanism 100 during installation.
The positioning ring 14 is used for receiving external force and acts on the adjusting component 16 to drive the adjusting component 16 to rotate, α degrees can be set after the positioning ring 14 is stressed, α degrees can be simultaneously rotated by the power receiving port 11 after the positioning ring 14 controls the adjusting component 16 to rotate α degrees, and interference with the driving mechanism 100 can be avoided, and fig. 18 and 19 are schematic diagrams showing that when the positioning ring 14 receives external force F, the adjusting component 16 and the power receiving port 11 rotate α degrees along the direction W shown in the figure.
Fig. 20 to 22 are schematic views of a state that the positioning ring 14 controls the rotation of the adjusting component 16 and the power receiving port 11 under the condition that the first engaging portion 142 on the positioning ring 14 is not engaged with the second engaging portion 161 on the adjusting component 16 at the initial position.
As shown in fig. 20, when the retainer ring 14 is at the initial position, the angle between the first engaging portion 142 and the initial position of the second engaging portion 161 of the adjusting member 16 is β, fig. 21 shows that the first engaging portion 142 engages with the second engaging portion 161 after the retainer ring 14 is rotated by β degrees in the W direction after being applied with the force F, and fig. 22 shows that the adjusting member 16 and the power receiving port 11 reach the position after being driven to rotate by α minus β degrees after the retainer ring 14 is further rotated by α minus β degrees after being applied with the force F.
When the power receiving port 11 is at the initial position, the shortest distance between the jaws is N2, wherein N2 is smaller than d; as shown in fig. 22, after the power receiving port 11 is controlled to rotate, the distance N3 between the jaws 111 on the power receiving port 11 is greater than d, so that the power receiving port 11 can be prevented from interfering with the driving mechanism during installation.
In this technical solution, the control mechanism can simultaneously control the power receiving port 11 to retract along its rotation axis and rotate around its rotation axis, and the elastic element 17 is used to extend the power receiving port 11 along its rotation axis after the power receiving port 11 is installed in place.
In this embodiment, the control mechanism includes the positioning ring 14, the guide sleeve 15, and the adjusting component 16.
In order to realize the source of the external acting force, the internal structure of the machine does not need to be borrowed, and the external acting force can be provided only when a user installs the processing box, so that the effect of stable source of the external acting force can be achieved. The present solution provides the preferred solution as shown in fig. 23.
Fig. 23 is a schematic structural view of the control mechanism. The control mechanism is arranged on a housing 101 of the processing box 10, the power receiving port 11 is arranged on one end of the processing box in the longitudinal direction and is used for being meshed with a driving mechanism 100 arranged in the image forming device to transmit power, and when the power receiving port 11 and the driving mechanism 100 are meshed with each other, the power receiving port 11 and the driving mechanism 100 are in a coaxial state.
As shown in fig. 23, the control mechanism 9 of the present embodiment includes a push rod 91, wherein the push rod 91 is further provided with a first rack 911; the control structure further includes intermediate transfer gear sets 92 and 93, a second rack 94, a link 95, a pressing plate 96, and an elastic member 97.
The intermediate transfer gear set includes a first transfer gear 92, and a second transfer gear 93; the second transmission gear 93 is coaxially provided with a first external gear 931, and a second external gear 932.
The first rack 911 of the push rod 91 is engaged with the first transmission gear 92, and the first transmission gear 92 is simultaneously engaged with the first external gear 931 of the second transmission gear 93; a second external gear 932 on the second transfer gear 93 is meshed with the second rack 94; the second rack 94 is hinged with one end of the connecting rod 95; the other end of the connecting rod 95 is hinged with one end of the pressing plate 96; the elastic member 97 is disposed between the pressing plate and the casing 101 of the process cartridge 10.
One end of the push rod 91 is connected with the positioning ring 14; when the user holds the process cartridge 10 and presses the pressing plate 96, the pressing power is transmitted to the push rod 91 through the link 95 and the rack 94, the gears 93 and 92 are transmitted, and the bezel 14 is pushed to rotate by the push rod 91. The force of holding the processing box by a user can be used as the source of the external acting force F, so that the aim of avoiding interference with the driving mechanism 100 and smoothly installing the processing box 10 can be fulfilled by controlling the installation process of the power receiving port 11 through the control mechanism.
Thus, in this embodiment, the control mechanism further includes a pressing plate 96, an elastic member 97, a link 95, a rack 94, transfer gears 93 and 92, and a push rod 91.

Fig. 37 is a perspective view of a hub 23 according to the present embodiment, and fig. 38 is a cross-sectional view of the hub 23.
The hub 23 is a rotary body and is rotatable relative to the casing of the process cartridge; the hub 23 is internally provided with a hollow part 232, the inner circumferential direction of the hub is also provided with a pair of force-bearing columns 233, at least one pair of force-bearing columns 233 is arranged, a gap 231 is also arranged between the force-bearing columns 233, the upper surface of each force-bearing column 233 is 2331, and the lower surface of each force-bearing column 233 is 2332.
FIG. 39 shows a partial structural view of the present embodiment, wherein the sliding blocks are disposed in the axial direction of the power receiving port 21, as shown, the sliding blocks are disposed in the gaps 231 between the force receiving posts 233, in this case, the gaps 231 are sliding grooves, the sliding grooves 231a and 231b are inclined with respect to the rotation axis L4 of the hub 23, as shown in FIG. 38, the direction K shown in FIG. 38 is a direction parallel to the direction in which the sliding grooves 231 are disposed, and the direction K forms an angle with the axis L4. the sliding blocks are disposed in a pair, respectively 24a and 24b, the sliding blocks 24a and 24b are disposed in the sliding grooves 231a and 231b, respectively, the sliding blocks 24 are slidable in the sliding grooves 231. the sliding grooves 231a and 231b are disposed in the hub 23 in directions not parallel to each other, and are both in an angular relationship with the rotation axis L4 of the hub 23.
Referring to fig. 39, a first transmission pin 25 and a second transmission pin 26 are provided along a main body portion of the power receiving port 21, and the transmission pins 25 and 26 pass through the main body portion of the power receiving port 21 and protrude in a radial direction of the main body portion.
Referring to fig. 40, the second transmission pin 26 is used for cooperating with the sliding block 24a (24b), the bottom of the sliding block 24a (24b) is provided with a guide surface 24a1(24b1), and the guide surface 24a1(24b1) is an inclined surface; when the power receiving port 21 is engaged with a driving mechanism 100 in the image forming apparatus to transmit power and the power receiving port 21 is rotated around a direction W1, the power receiving port 21 drives the second transmission pin 26 to rotate around a direction W1 and pushes the guide surface 24a1(24b1), so that the sliding block 24a (24b) extends along the sliding groove 231a (231b) to the end part direction close to the claw 211 of the power receiving port 21, and the second transmission pin 26 can abut against the lower bottom surface 2332 of the hub 23 to limit the distance of the power receiving port 21 to slide along the axial direction; when the sliders 24a and 24b extend in the direction toward the end where the pawl 211 close to the power receiving opening 21 is located, as shown in fig. 41, when the power receiving opening 21 is engaged with a driving member 100 (not shown) in the image forming apparatus to transmit power, the power receiving opening 21 is rotated around the direction W1, and the first transmission pin 25 is driven to rotate around the direction W1, at this time, the first transmission pin 25 can be engaged with the slider 24a (24b) to transmit power, and the hub 23 is driven to rotate around the direction W1 through the force-receiving column 233. In this embodiment, when the sliding block 24 does not extend in the direction of the end portion near the claw 211 of the power receiving opening 21, the first transmission pin 25 is supported by the upper surface 2331, and the power receiving opening 21 does not rotate to drive the hub 23 to rotate.

When the power receiving port 21 drives the second transmission pin 26 to rotate around the direction W1, so that the sliding blocks 24a and 24b extend in the direction close to the end where the claw 211 of the power receiving port 21 is located, the bosses 24a2 and 24b2 act on the elastic element 27 and compress the elastic element 27; when the power receiving port 21 stops rotating, the sliders 24a and 24b slide in the sliding groove 231 in a direction away from the end where the claws 211 of the power receiving port 21 are located under the resilient force of the elastic element 27.
Fig. 42 to 44 are schematic views showing a state in which the driving member 100 drives the power receiving port 21 to rotate after the image forming apparatus is started when the power receiving port 21 is engaged with the driving member 100 in the image forming apparatus.
Fig. 42 shows an initial state of the power receiving port 21. In the initial state, the top of the second protrusion 282 of the adjusting member 28 abuts against the bottom of the sliding member 291, and the slider 24 is disposed below the adjusting member 28.
Fig. 43 is a view showing a state after the power receiving port 21 is driven to rotate in the direction of W1. When the driving member 100 is engaged with the power receiving port 21 to transmit power, the power receiving port 21 is driven to rotate in the direction of W1, the first protruding portion 212 protruding in the radial direction of the power receiving port 21 pushes the third protruding portion 2902 on the rotating member 290, and the rotating member 290 rotates in the direction of W2, the second protruding portion 2901 forces the second protruding portion 2922 of the torsion spring 292 to twist in the direction of W2, and the second protruding portion 2922 of the torsion spring 292 contacts the third protrusion 2911 on the sliding member to push the sliding member 291 to slide along the sliding groove 223 on the positioning ring 22, i.e. to slide in the direction of T shown in the figure; meanwhile, the power receiving port 21 drives the second transmission pin 26 to rotate around the direction W1, and the sliding blocks 24a and 24b slide along the sliding grooves 231a and 231b arranged in the hub 23 to extend towards the direction close to the jaws 211 on the power receiving port 21 through the guide surfaces 24a1 and 24b1 on the bottoms of the sliding blocks 24a and 24b, and abut against the bottom surface of the adjusting component 28, so that the adjusting component 28 is lifted up towards the jaws 211; when the power receiving opening 21 rotates to be out of contact with the second protrusion 2902 of the rotating member 290, the torsion spring 292 rebounds, the second protrusion 2922 contacts the fourth pillar 2912 of the sliding member 291, and forces the sliding member 291 to slide in the direction opposite to the T direction and contact the inclined surface 2821 of the first pillar 282 of the adjusting member 28, and at this time, the sliding member 291 is stopped from sliding in the direction opposite to the T direction by the first pillar 292.
Fig. 44 shows a partial structural view. As can be seen from fig. 44, when the rotating member 290 is forced to rotate in the direction of W2 by the first protrusion 212 on the power receiving port 21, the torsion spring 292 can be twisted by the rotating member 290, and the sliding member 291 can be driven to slide.
FIG. 45 is a view showing a position where the power receiving port 21 stops rotating when the image forming apparatus stops after the power receiving port 21 is driven to rotate, when the first projection 212 of the power receiving port 21 is located on the back side of the fourth column 2912 of the slide member 291, as shown in FIG. 45, when the power receiving port 21 is located at a position where the center line L3 of the latch 211 is parallel to the process cartridge mounting direction (the X direction shown in FIG. 46), when one latch 211 of the power receiving port 21 is located behind the driving member 100 as seen in the process cartridge mounting direction, when a process cartridge is taken out in the direction opposite to the process cartridge mounting direction, the power receiving port 21 cannot be disengaged from the driving member 100, so that the process cartridge cannot be detached from the image forming apparatus.
At this time, in order to detach the process cartridge from the image forming apparatus, the power receiving port 21 needs to be controlled by the control mechanism to rotate around its rotation axis after stopping its rotation, and the process cartridge needs to be detached by avoiding the above-mentioned position.
With the technical solution provided by this embodiment, after the power receiving opening 21 stops rotating, the second protruding portion 2922 on the torsion spring 292 releases its twisting force and abuts against the fourth pillar portion 2912 on the sliding member 292, so as to force the sliding member 291 to move in the direction opposite to the direction T in the sliding groove 223; while the sliding member 291 moves, the adjusting member 28 is forced to slide in a direction away from the claw 211 by the inclined surface 2821; the adjustment member 28 slides while forcing the sliders 24a and 24b to slide in the slide slot 231 in a direction away from the jaws 211 of the power receiving port 21 until the first transmission pin 25 is disengaged from the sliders 24a and 24b when the bottom surfaces 24a2 and 24b2 of the sliders 24a and 24b, which were originally engaged with the first transmission pin 25, are lower than the upper surface 2331 of the hub; at this time, the restriction of the rotation of the power receiving port 21 around the rotation axis disappears; when the fourth pillar portion 2912 of the sliding member 291 contacts the first protrusion 212 of the power receiving port 21, the power receiving port 21 is forced to rotate in the direction of W1, while the driving member 100 remains stationary, so that the latch 211 at the end of the power receiving port 21 is disengaged from the protrusion 101 of the driving member 100.
After the power receiving port 21 is rotated, the state shown in fig. 47 can be realized, that is, the state shown in fig. 47 is reached by the technical solution provided by this embodiment, that is, the power receiving port 21 is in the state shown in fig. 46, and the state shown in fig. 47 is that the central connecting line L3 of the clamping jaw 211 on the power receiving port 21 is in the state intersecting with or approximately perpendicular to the mounting direction X of the process cartridge.
EXAMPLE five
Fig. 48 to 56 show still another embodiment provided by the present application, which can be implemented such that before the process cartridge is mounted into the image forming apparatus, the center line of the pawl at the end of the power receiving port on the process cartridge is in a direction substantially perpendicular to the mounting direction of the process cartridge, as shown in fig. 34 and 35 in the above-described embodiment.
Fig. 48 is a perspective view of a power receiving port 31 according to the present embodiment. The free end parts of the power receiving ports 31 are provided with a pair of clamping jaws 311 along the axial direction and are symmetrically arranged around the rotating axis; the power receiving port 31 further comprises a main body 313, wherein a boss part 312 protruding in the radial direction is arranged on the main body 313, the boss is arranged in a cam structure, the cross section of the cam can be arranged in an oval shape, or a rhombic shape or other shapes with unequal widths in the directions perpendicular to each other and crossing each other are arranged.
Fig. 49 is an assembly view showing a part of the structure of the present embodiment. The processing box is also provided with a hub 33 with a rotation axis, and the power receiving port 31 is arranged in the hub 33 in a penetrating way along the axial direction of the hub 33. The control mechanism comprises an elastic element, the elastic element is arranged on the processing box, one part of the elastic element is relatively fixedly arranged with the shell of the processing box, and the other part of the elastic element is abutted against the power receiving port 31.
The elastic element may be the elastic sheet member 32 shown in fig. 49, one end 321 of the elastic sheet member 32 is disposed on the end cap 103 fixed to the process cartridge housing (as shown in fig. 50), and the other free end 322 of the elastic sheet member 32 abuts against the outer surface of the boss portion 312 disposed on the power receiving port 31 (as shown in fig. 49).
Fig. 51 shows the relative positional state of the elastic member 32 and the power receiving port 31 before the process cartridge is mounted in place in the image forming apparatus. Referring to fig. 51, in a natural state, the free end 322 of the spring member 32 abuts against the side surface of the boss portion 312 on the power receiving port 31 and abuts against a position where the boss portion 312 is closer to the rotation axis of the power receiving port 31 in the radial direction of the power receiving port 31. Since the positions of the claws 311 on the power receiving ports 312 and the boss parts 312 are relatively fixed, the claws 311 can be in a position relatively fixed with the casing of the process cartridge by pushing the boss parts 312 through the spring members 32. Thus, as will be understood by those skilled in the art, the center line of the claws 311 is brought into a state of being substantially perpendicular to the mounting direction of the process cartridge (X direction in fig. 51) by urging the boss portions 312 on the power receiving ports 31 by the resilient piece members 32, thereby allowing the end portions 102 of the driving member 100 provided in the image forming apparatus to pass through the gaps between the claws 311 during the mounting of the process cartridge, thereby completing the mounting of the process cartridge.
Fig. 52 is a schematic view showing the state of the resilient member in the process of engaging the power receiving opening 31 with the driving member 100 to transmit power after the process cartridge is mounted in place.
After the driving member 100 drives the power receiving port 31 to rotate around the direction of W1, the boss portion 312 is always abutted against the free end 322 of the elastic sheet member 32, and the boss portion 312 urges the free end 322 to swing around the bending portion 323 connecting the fixed end 321 and the free end 322 on the elastic sheet member 32 between the position of a1 and the position of a 2.
When the driving member 100 of the image forming apparatus stops operating, the power receiving port 31 stops rotating. When the power receiving port 31 stops and the elastic sheet part 322 abuts against the longer width part of the cross section of the boss part 312 of the power receiving port, the boss part 312 is pushed to force the power receiving port 31 to rotate around the rotation axis of the power receiving port under the action of the resilience force of the free end 322 until the free end 322 has no or almost no resilience force at the shorter width part of the cross section of the free end 322 of the elastic sheet part 32 and the boss part 312.
The elastic member 32 in the present embodiment may also be a spring 32A as shown in fig. 53 to 53. One end of the spring 32A is fixed to the casing of the process cartridge, and when the larger width of the cross section of the boss 312 provided in the radial direction on the power receiving port 31 abuts against one end of the spring 32A (as shown in fig. 53), the spring 32A is in a compressed state; when the driving member 100 of the image forming apparatus stops operating and the power receiving port 31 stops rotating, the resilient force of the spring 53 urges the boss portion 312 and the power receiving port 31 to rotate about the rotation axis thereof.
The elastic member 32 in this embodiment may also be a torsion spring 32B as shown in fig. 55 to 56. The torsion spring 32B is sleeved on a portion of the torsion spring 32B relatively fixed to the casing of the process cartridge, for example, on the end cover 103 which can be relatively fixedly disposed to the process cartridge, the torsion spring 32B is sleeved on the positioning post 1031a disposed on the end cover 103, the first protruding portion 32B1 of the torsion spring 32B abuts against the side surface of the boss portion 312, and the second protruding portion 32B2 of the torsion spring member 32B abuts against a portion of the torsion spring 32B relatively fixed to the process cartridge, for example, against the stopper 1031B disposed on the end cover 103.
The principle of the above-mentioned springs 32A and 32B controlling the relative position of the power receiving port 31 on the rotation axis thereof and the process cartridge by their resilient force is the same as the principle of the spring member 32, and will not be described herein again.

From the above description, those skilled in the art will understand that with the solution provided in this embodiment, the power receiving port 61 can be controlled by the control mechanism to be in the retracted state in the Y direction before the process cartridge 30 is installed into the image forming apparatus.
Referring to fig. 68, after the process cartridge 30 is installed in the image forming apparatus and is installed in place, an external force F is applied to the first push rod 305, the first push rod 305 drives the gear unit 307 to rotate, and the second gear 3072 on the gear unit 307 is engaged with the rack 3061 on the second push rod 306, so that the second push rod 306 retracts in the direction opposite to the direction X in the figure against the elasticity of the elastic element 308, and drives the positioning ring 62 to rotate in the direction opposite to the direction W in the figure 75; at this time, the second engaging portion 621 of the positioning ring 62 is disengaged from the first engaging portion 3031 of the end cap, and the power receiving port 61 is extended in the direction opposite to the Y direction by the resilient force of the elastic member 68 and is engaged with the driving member 100 in the image forming apparatus.

When the door cover is opened, the external force F is weakened or disappears, and the second push rod 306 is forced to push the positioning ring 62 to rotate around the direction W shown in fig. 75 under the resilience of the elastic element 308.
How to make the center connecting line L3 of the pawl 611 on the power receiving port 61 in a state substantially perpendicular to the mounting direction of the process cartridge before the process cartridge is mounted into the image forming apparatus by the technical solution of the present embodiment will be described below by referring to fig. 77 and 78.
Referring to fig. 77, the torsion spring member 65 is disposed between the sleeve 64 and the adjusting member 66, and the first free end 651 of the torsion spring member 65 is engaged with the second engaging groove 641 of the sleeve 64, and the second free end 652 of the torsion spring member 65 is engaged with the first engaging groove 661 of the adjusting member 66; according to the above-mentioned relation, after the sleeve 64, the torsion spring member 65, and the adjusting member 66 are assembled, the three are coaxially arranged and constrained to each other in the circumferential direction; meanwhile, a transmission pin 67 is arranged to penetrate through the power receiving port 61 along the radial direction of the main body 612 of the power receiving port 61, the power receiving port 61 is arranged to penetrate through the adjusting component 64, and meanwhile, two ends of the transmission pin 67 extending out along the radial direction of the power receiving port 61 are arranged between the placement grooves 642 axially arranged on the sleeve 64, and the placement grooves 642 are a pair and symmetrically arranged along the circumferential direction of the power receiving port 61.
When one of the sleeve 64, the torsion spring member 65 and the adjusting member 66 is driven to rotate around the rotation axis thereof, the other two members are driven to rotate around the rotation axis; for example, when the fourth engaging portion 662 of the adjusting member 66 is engaged with the third engaging portion 622 of the positioning ring 62 and is rotated by the positioning ring 62, the sleeve 64 and the torsion spring member 65 are rotated; or, when the power receiving port 61 is engaged with the driving member disposed in the image forming apparatus to transmit power, the power receiving port 61 is driven to rotate, the sleeve 64 is driven to rotate by the transmission pin 67, the sleeve 64 drives the torsion spring member 65 to rotate, and then the torsion spring member drives the adjusting member 66 to rotate.
Therefore, through the above description, it can be known that after the power receiving port 61, the transmission pin 67, the sleeve 64, the torsion spring member 65 and the adjusting member 66 are assembled, the relative positions of the transmission pin 67 and the pawl 611 on the power receiving port 61 are fixed, so that the positions of the pawl 611 on the power receiving port 61 and the fourth engaging portion 662 arranged on the adjusting member 66 are also fixed relatively.
The fourth engaging portions 662 provided on the adjusting member 66 are a pair and are symmetrically provided in the circumferential direction of the adjusting member 66, as shown in fig. 77. Thus, it can be understood that when the third engaging portion 622 on the positioning ring 62 is engaged with the fourth engaging portion 662 provided on the adjusting member 66, the adjusting member 66 is rotated and the power receiving opening 61 is rotated.
Referring to fig. 78, the maximum sliding stroke of the second push rod 306 is N4, and the maximum angle of rotation of the positioning ring 62 can be controlled to be θ, so that when the fourth engaging portion 662 of the adjusting member 66 is within the range of the rotating stroke of the positioning ring 62, the positioning ring 62 can drive the adjusting member 66 to rotate, and then the power receiving port 61 is driven to rotate by the adjusting member 66, so that the relative state of the center connecting line L3 of the claw 611 on the power receiving port 61 and the mounting direction X of the process cartridge can be adjusted.
Referring to fig. 79a to 79b, the dimension of the outer periphery of the free end portion of the driving mechanism 100 in the image forming apparatus is set to d, and when the shortest distance between the pair of claws 611 in the power receiving port 61 is N1, that is, when N1 is d, the claws 611 just avoid interfering with the free end portion 102 of the driving mechanism 100 during the process cartridge is mounted into the image forming apparatus, and the line connecting the positions of the fourth engaging portions 662(662a, 662b) of the regulating member 66 is set to L1.
Fig. 17 shows another position of the adjusting member 66 and the power receiving port 61 when the shortest distance between the claws 611 on the power receiving port 11 is N1, and N1 is d, and the claws 611 just avoid interfering with the free end 102 of the driving mechanism 100, and the connecting line between the engaging portions 662a and 662b is L2.
The angle between the connecting lines L1 and L2 of the engaging portions at two positions of the adjusting component 66 shown in fig. 79a and 79b is related to the external dimension d of the free end 102 of the driving mechanism 100, when the claws 611 on the power receiving port 61 are not in the range of the angle, the power receiving port 11 is not interfered with the free end of the driving mechanism 100 when the process cartridge is installed, and when the claws 611 of the power receiving port 61 are in the range of the angle, the power receiving port 61 needs to be controlled by a control mechanism to rotate around the rotation axis thereof, so that the power receiving port 61 can be prevented from interfering with the driving mechanism during the installation process, and the free end of the driving mechanism 100 is positioned in the space between the claws 611 on the power receiving port 61, and the power receiving port 61 can be smoothly engaged with the driving mechanism 100 (as shown in fig. 80).
After the processing box is installed into the image forming device, the power receiving port is meshed with a driving part 100 arranged in the image forming device; after the image forming apparatus is started, the driving member 100 drives the power receiving port 61 to rotate around the W direction shown in fig. 75, the power receiving port 61 drives the sleeve 64 to rotate through the transmission pin 67, and the sleeve 64 cooperates with the second locking groove 641 on the sleeve 64 through the first free end 651 of the torsion spring member 65 and drives the torsion spring member 65 to rotate; referring to fig. 76, after the first free end 651 of the torsion spring member 65 rotates around its own rotation axis, the torsion spring member 65 simultaneously embraces the outer surface of the first cylindrical body 64 of the sleeve 64 and the outer surface of the cylinder 632 arranged in the hub 63 on the inner circumference of the torsion spring member 65, and the hub 63 is simultaneously driven to rotate by the embracing action (i.e., tight fit) of the torsion spring member 65; meanwhile, the cross section of the torsion spring part 65 is of a rectangular structure, and in order to increase the contact area between the torsion spring part 65 and the sleeve 64 and between the torsion spring part and the hub 63, the torsion spring part is convenient to drive the parts to rotate by holding tightly.
It should be noted that when the torsion spring member 65 rotates in the direction opposite to the direction W, the torsion spring member 65 does not have a holding effect on the hub 63 and the cylindrical outer surface of the sleeve 64.
Referring to fig. 81a to 81b, the third engagement portion 622 of the positioning ring 62 is provided with a first inclined surface 6221 on one side and a first engagement surface 6222 on the other opposite side; a fourth engaging portion 662 provided on the adjusting member 66, one side of which is provided with a second inclined surface 6622, and the other side of which is provided with a second engaging surface 6621; when the first engaging surface 6222 of the positioning ring 62 is engaged with the second engaging surface 6621 of the adjusting member 66, the positioning ring 62 actively rotates to drive the adjusting member 66 to rotate; when the positioning ring 62 is rotated reversely, the first inclined surface 6221 on the positioning ring 62 is engaged with the second inclined surface 6622 on the adjusting member 66, and the first inclined surface 6221 and the second inclined surface 6622 slide relatively, so that the adjusting member 66 cannot be driven to rotate.

The control mechanism is further provided with an elastic element 404, one end of the elastic element 404 abuts against the second push rod 403 in the moving direction of the second push rod 403, and the other end abuts against a part of the relatively fixed processing box shell 401; the resilient member 404 may preferably be a spring.
When the elastic element 404 is in a natural extension state, the second push rod 403 extends in the direction of the arrow shown in fig. 82; when the first push rod 402 receives an external force, the second push rod 403 is moved in the direction opposite to the arrow shown by the action of the rack and pinion against the elastic force of the elastic element 404.

The control mechanism is further provided with a positioning ring 78, a guide sleeve 72, a limiting part 77 and an end cover 79, and fig. 84 and 85 show the assembly schematic diagram of the positioning ring 78, the guide sleeve 72, the limiting part 77 and the end cover 79. The limiting part 77 is matched with the end cover 79 and can be used for limiting the rotation of the guide sleeve 72 relative to the rotation axis of the guide sleeve. Preferably, one or more first limit stoppers 721 are arranged on the guide sleeve 72, one or more first limit interfaces 771 are arranged on the limiting component 77, and the first limit stoppers 721 can pass through the first limit interfaces 771; the limiting component 77 is further provided with a second limiting clamping block 772, the end cover 79 is provided with a second limiting interface 791, and the second limiting clamping block 772 is matched with the second limiting interface 791. When the assembly is completed, the end cap 79 is fixed relative to the process cartridge case 401, and the guide bush 72, and the stopper member 77 are restricted in the degree of freedom in the rotational axis thereof.
Referring to fig. 83 to 85, the positioning ring 78 is provided with an inclined surface 781, and the guide sleeve 72 is provided with an inclined surface 7211; the positioning ring 78 is connected with the second push rod 403, and the rotation of the positioning ring 78 on the rotation axis thereof is controlled by the movement of the second push rod 403.
After the positioning ring 78 is controlled to rotate around the direction W shown in fig. 85, the inclined surface 781 provided on the positioning ring 78 is matched with the inclined surface 7211 provided on the guide sleeve 72, and the guide sleeve 72 is forced to slide along the axial direction (the direction Y shown in fig. 85) because the rotation freedom of the guide sleeve 72 is limited.
Fig. 86 is an assembled half sectional view of the components shown in fig. 83. The processing box is also provided with a hub 74 along the length direction, the hub 74 is a rotary body, the positioning ring 78, the limiting part 77 and the guide sleeve 72 are coaxially arranged along the rotary axis direction of the hub 74; meanwhile, the power receiving port 71 penetrates through the end cover 79, the positioning ring 78, the limiting part 77 and the guide sleeve 72 and is arranged in the hub 74.
A first snap spring 701 is arranged on the periphery of the power receiving port 71 along the radial direction and is abutted against one bottom surface of the guide sleeve 72; after the positioning ring 78 controls the guide sleeve 72 to slide along the Y direction, the guide sleeve 72 can be abutted against the first snap spring 701 at the same time, so that the power receiving port 71 is forced to move along the Y direction.
Referring to fig. 83, the end of the hub 74 is provided with a first engagement portion 741, and engages with a second engagement portion 751 provided on a transmission member 75 to transmit power. In an initial state of completed assembly, the first engagement portion 741 provided on the hub 74 and the second engagement portion 751 are engaged with each other (see fig. 83); a first boss portion 713 is arranged in the radial direction of the power receiving port 71, and when the guide sleeve 72 is controlled by the positioning ring 78 to drive the power receiving port 71 to slide along the Y direction, the transmission member 75 is forced to slide along the Y direction by the first boss portion 713, and the second engagement portion 751 is disengaged from the first engagement portion 741.
An elastic element 73, preferably a spring, is further sleeved along the direction of the rotation axis of the power receiving opening 71. One end of the elastic element 73 is abutted against the inner surface of the hub 74 in the radial direction, and the other end is abutted against the bottom surface of the guide sleeve 72 in the radial direction; the power receiving port 71 is further provided with a second boss portion 714 along the radial direction, and the second boss portion 714 is abutted to the upper surface of the guide sleeve 72. When the power receiving port 71 slides along the Y direction, the elastic element 73 is compressed; when the rotation power applied to the positioning ring 78 is cancelled, the elastic element 73 rebounds, so that the guide sleeve 72 is forced to drive the power receiving opening 71 to extend out in the opposite direction of the Y direction. The radial direction of the power receiving port 71 is also provided with a second snap spring 702 which is clamped with the periphery of the power receiving port 71 and used for limiting the transmission component 75 to be disengaged from the power receiving port 71.
The lower end of the power receiving port 71 is matched with the transmission component 75 to form a non-circular cylinder, a non-circular hole is formed in the middle of the transmission component 75 to be matched with the non-circular cylinder, and the transmission component 75 can be driven to rotate simultaneously after the power receiving port 71 is driven to rotate.
How to smoothly mount the process cartridge 40 into the image forming apparatus and how to smoothly dismount the process cartridge 40 from the image forming apparatus will be described below with reference to the present preferred embodiment.
Referring to fig. 87, a perspective view of the power receiving port 71 is shown. The power receiving port 71 is provided with a cam portion 712 along the axial direction thereof, and the illustration B-B is a cross-sectional view of the cam portion 712.
Referring to fig. 83 and 88, the control mechanism further includes an elastic member 76, and the elastic member 76 urges the cam portion. In the present preferred embodiment, the elastic member 76 is provided as a pair of torsion spring members, a first torsion spring member 761, and a second torsion spring member 762, for more stably controlling the position of the cam portion 712.
Specifically, the torsion spring member 76 is mounted on the limiting member 77 through a positioning post 773 provided on the limiting member 77. The torsion spring member 76 includes two free ends, one of which 7612 and 7622 abuts against the inner surface of the restricting member, and the other of which 7611 and 7612 abuts against the outer peripheral surface of the cam portion 712 of the power receiving port 71, and has a resilient action on the power receiving port 71.
Fig. 89 shows a front view and a corresponding top view of the power receiving port 71, wherein a pair of jaws 711 which are symmetrical to each other are arranged at the end part of the power receiving port 71, and a line L3 which connects the end points of the pair of jaws 711 and intersects with the axis of the power receiving port 71 is a central line of the pair of jaws 711.
Fig. 90 and 91 are schematic views showing a state in which the cam portion 712 is controlled by the torsion spring member 76 to restrict the position of the pair of pawls 711 on the power receiving port 71. The cam part 712 is connected with the power receiving port 71, and when the power receiving port 71 rotates around the rotation axis of the power receiving port, the cam part 712 is driven to rotate around the rotation axis of the power receiving port (the rotation is in the direction of the arrow shown in fig. 91), so that the position of the cam part is changed, acting force is generated on the free ends 7611 and 7621 of the torsion spring part 76, and the free ends of the torsion spring part 76 generate resilience force after being rotationally tightened; when the rotary power of the power receiving port 71 is removed, the resilience force of the torsion spring member 76 is released, so that the cam portion 712 is forced to rotate to the initial position, and the power receiving port 71 is simultaneously driven to rotate.
Specifically, referring to fig. 90 and 91, since the relative positions of the pawl 711 and the cam portion 712 are fixed, the cam portion 712 can be controlled by the torsion spring member 76 to control the position of the pawl 712 in the rotation circumferential direction of the power receiving port 71, when the respective members are assembled, the free ends 7611 and 7621 of the torsion spring member 76 abut against the outer circumferential surface of the cam portion 712 to force the cam portion 712 to be in a relatively fixed position with respect to the cartridge housing when no external force is applied, and thus, the pawl 711 is also in a relatively fixed position with respect to the cartridge housing in the initial state, the X direction of fig. 90 is the direction in which the cartridge is mounted into the image forming apparatus, and in the initial state, the center connecting line L3 of the pair of pawls 711 forms a relatively fixed angle with the mounting direction X of the cartridge, which angle is formed by the position of the cam preset by the designer, the designer controls the position of the cam portion 712 by setting the torsion spring member 76 such that the angle is an arbitrary value between 0 ° and 180 °.
In order to prevent the engagement of the pawl 711 with the free end 102 of the driving mechanism 100 provided in the image forming apparatus as shown in fig. 92 when the process cartridge is mounted into the image forming apparatus in the X direction, thereby preventing the process cartridge from being smoothly mounted into the image forming apparatus, or in order to prevent the engagement of the pawl 711 with the end of the driving mechanism 100 as shown in fig. 93 when the process cartridge is removed from the image forming apparatus in the reverse direction in the X direction, thereby preventing the removal of the process cartridge, it is necessary to control the center line L3 of the pawl 711 by the cam member 712 so as to prevent the angle of 0 ° or 180 ° from being formed with the mounting direction X direction of the process cartridge, the optimum value being 45 ° to 135 °, and the optimum value being when the angle is 90 °, therefore, the pair of pawls 711 should be controlled to the initial positions so that the pair of pawls 711 are distributed on both sides 71 parallel to the mounting direction of the process cartridge and passing through the plane including the power receiving port, i.e., when viewed from the mounting direction X direction, the one pawl is located above, and the other pawl is located below the mounting direction, thereby achieving the purpose of the process cartridge.
According to the technical scheme of the embodiment, before the processing box is installed in the image forming device, the power receiving port slides for a distance H along the rotation axis direction of the power receiving port through the control mechanism.
Referring to fig. 94, before the process cartridge is mounted in the image forming apparatus, the power receiving port 71 is moved by a distance H in the direction of the rotation axis (shown as the Y direction) thereof by the control mechanism while disengaging the first engaging portion 741 on the hub 74 from the second engaging portion 751 on the transmitting member 75, so that the power receiving port 71 and the hub 74 are relatively rotatable; when the process cartridge is mounted in the image forming apparatus, the power receiving port 71 is extended in the reverse direction of the Y direction by the control mechanism, and drives the transmission member 75 to extend to reengage with the hub 74; when the process cartridge is mounted in place, the power receiving port 71 receives rotational power from the driving mechanism 100 provided in the image forming apparatus, and drives the hub to rotate.
Referring to fig. 95, after the process cartridge is assembled, the elastic element 404 pushes the push rod 403 to control the positioning ring 78 to be at the position K1, and the position of the claws of the power receiving opening 71 and the position of the process cartridge housing are fixed relatively by the positioning ring 78; after the processing box is installed in the image forming device, external force is applied to the first push rod 402, and power is transmitted through the gear rack, so that the second push rod 403 drives the positioning ring to rotate to the position shown in the figure K2 by an angle theta 1; at this time, the power receiving port realizes the transition from the state of being initially positioned to retract towards the inside of the process cartridge to the state of being extended towards the outside of the process cartridge; after the external force is removed, under the action of the resilience force of the elastic element 404, the second push rod 403 drives the positioning ring 78 to return to the position K1, and the power receiving port 71 returns to the retracted state from the extended state.
Example ten
According to the concept of the technical solution of the present application, a person skilled in the art can appropriately change or optimize the specific structure. The embodiment is one of structural optimization performed according to the concept of the present application.
Referring to fig. 96, in the present embodiment, the structures of the guide sleeve 72 and the restricting member 77 in the ninth embodiment are optimized to simplify the structure. Specifically, the guide sleeve 72 and the limiting member 77 are designed into a whole through optimization, the guide sleeve 82 is matched with the end cover 84, and other parts, such as the positioning ring 83, the power receiving opening 81 and the torsion spring member 85, keep the structure basically similar to that of the ninth embodiment.
The guide sleeve 82 is provided with an inclined surface 821 for matching with an inclined surface 831 arranged on the positioning ring 83; the guide sleeve is provided with a limiting interface 823 which is used for being provided with a limiting fixture block 841 on the end cover; after being assembled, the end cover 84 is fixed relative to the housing of the processing box, so that the degree of freedom of the guide sleeve 82 rotating around the rotation axis direction thereof can be limited by the limiting fixture block 841; therefore, when the retainer ring 83 rotates relative to the casing, the inclined surface 821 of the guide sleeve is forced by the inclined surface 831 of the retainer ring to slide the guide sleeve in the axial direction thereof, and the power receiving opening 81 is controlled to move in the axial direction by the abutment of the lower bottom surface of the guide sleeve 82 with the upper surface of the snap spring member 86. The guide sleeve 82 is also provided with a positioning column 822 for mounting the torsion spring part 85; because the torsion spring component 85 is fixed relative to the guide sleeve, when the guide sleeve 82 controls the power receiving port 81 to move axially, the torsion spring component 85 and the power receiving port 81 move simultaneously, and the outer surface of the cam portion 812 is prevented from being damaged due to friction between the torsion spring component 85 and the cam portion 812 on the power receiving port 81 when the torsion spring component 85 and the power receiving port 81 move relatively.
The torsion spring member described in the present embodiment is only one preferable embodiment of the elastic element, and may be a spring, an elastic body, a magnet, or the like that can return the cam portion.

The power receiving port C210 is disposed in the hub C250, and the elastic member C279 is disposed between the inner bottom of the hub C250 and the power receiving port C210 and provides an elastic force; the fixed ring C271 is sleeved on the power receiving port C210 so that the rotation axis of the power receiving port C210 is parallel or coincident with the rotation axis of the hub C250; the control member C275 is arranged on the end cover C290, one end of the control member C275 is fixed on the fixing part C299 of the end cover C290, the other end of the control member C275 is in contact with the power receiving port C210 and makes it reset when not receiving the driving force of rotation, and the control member C275 can be a part with elastic restoring force, such as plastic or metal sheet, torsion spring, etc.; the end cover C290 is arranged on one side of the hub C250, and a part of the power receiving port C210, the elastic element C279, the control piece C275 and the fixing ring C271 are arranged between the end cover C290 and the hub C250.
The first and second rotary power receiving members of the power receiving port C210 are provided with pawls C211a, C211b, inclined surfaces C216a, C216b, a transmission portion C219a, C219b, a convex displacement portion C215a, C215b, and a slide groove C218b and a projection C218a which are slidably fitted to each other, the slide groove C218b is provided in the second rotary power receiving member C210b, and the projection C218a is provided in the first rotary power receiving member C210 a; the hub C250 is provided with gears on the outer surface and a force-receiving column C259 therein for receiving the rotational driving force from the transmission parts C219a, C219 b. In addition, the processing box C is further provided with an axial pushing component C300 matched with the driving component C200, the axial pushing component C300 comprises a pushing surface C301, an inclined surface C302, an abutting surface C303 and a stress end C309, and a height difference H5 exists between the pushing surface C301 and the abutting surface C303; an elastic member C279 has one end abutting against the force receiving end C309 of the axial urging member C300 and the other end abutting against the one end side wall b1 of the process cartridge C, and the urging surface C301, the inclined surface C302, and the abutting surface C303 of the axial urging member C300 are pressed by the external force of the force receiving end C309 to be applied to the inclined surface C216a/C216b of the first/second rotary power receiving member to control the axial extension or retraction movement of the first/second rotary power receiving member C210a/C210b with respect to the hub C250 or the end cap C290.
As shown in fig. 102 to 104, the first and second rotary power receiving parts C210a and C210b are provided in the hub C250, the first and second rotary power receiving parts C a and C210b are individually extendable or retractable in the axial direction by the provision of the elastic member C279 at the bottom of the rotary power receiving part C210a/C210b, when the axial urging member C300 is not pressed by an external force on the process cartridge C, the axial urging member C300 is moved backward with respect to the hub C250 by the elastic force of the elastic member C279 at one end of the axial urging member C300, the urging surface C301 at the front end of the axial urging member C300 is brought into contact with the top of the inclined surface C216a/C216b at the b end of the rotary power receiving part C210/C210 b to bring the rotary power receiving part C210C a/C210b into a pressed state, and the rotary power receiving part C a/C210C b is kept retracted inward with respect to the hub C250,
as shown in fig. 105 to 109, which are operation diagrams when the driving assembly C200 mounted in the process cartridge C is mounted in the image forming apparatus together with the process cartridge C, the process cartridge C is mounted in the image forming apparatus in the mounting direction X with its power receiving port C210 gradually approaching the driving part 100 provided in the image forming apparatus as the process cartridge C moves, the control mechanism 300 maintains an initial state by the elastic force of the elastic member C279, and the urging surface C301 of the axial urging member C300 is pressed against the inclined surface C216a/C216b of the rotary power receiving member C210a/C210b to maintain the rotary power receiving member C210a/C210b in a retracted state with respect to the hub C250. When the process cartridge C is mounted in place in the image forming apparatus, its power receiving opening C210 is kept substantially coaxial with the driving part 100 of the image forming apparatus, the axial urging member C300 is moved forward in the mounting direction X of the process cartridge C by an external force (such as a door cover, an urging mechanism in the image forming apparatus, or a manual force of a user) applied to the force-receiving end C309 of the axial urging member C300 from outside the process cartridge C, since the process cartridge C has been mounted in place in the image forming apparatus, during the displacement of the axial urging member C300 relative to the process cartridge C, the urging surface C301 of the front end of the axial urging member C300 will no longer contact the top of the inclined surface C216a/C316b of the power receiving port C210a/C210b, the resilient member C279 disposed at the bottom of the power receiving port C210 is thus released from compression and releases the resilient force to allow the power receiving port C210 to project outwardly relative to the hub C250 in the axial direction Y thereof into contacting engagement with the driving member 100.
As shown in fig. 110, 111, in the process that the power receiving port C210 is projected outward in the axial direction Y thereof into contact engagement with the driving part 100, the structure of the stopper F111 thereof overlaps with the structure of the driving part 100 as viewed in the axial direction Y, the first rotary power receiving member C210a in the power receiving port C210 is directly brought into contact engagement with the driving part 100 without interference during the projection, and the second rotary power receiving member C210b in the power receiving port C210 is resisted by the projecting end F111a of the stopper F111 during the projection so that the second rotary power receiving member C210b cannot be further projected into contact engagement with the driving part 100. After the first rotary power receiving part C210a is extended into contacting engagement with the driving part 100, the top of the inclined surface C216a of the first rotary power receiving part C210a also abuts the abutment surface C303 of the axial urging part C300 preventing excessive extension displacement of the first rotary power receiving part C210 a. In addition, as the second rotary power receiving element C210b is abutted by the protruding end F111a, the projection C218a of the first rotary power receiving element C210a may continue to move outwardly within the slide groove C218b of the second rotary power receiving element C210b with the displacement of the first rotary power receiving element C210 a.
After the above-mentioned cooperation is completed, the user starts the driving part 100 in the image forming apparatus and operates it, as shown in fig. 111, even if only one of the rotary power receiving members (i.e., the first rotary power receiving member C210a) of the power receiving port C210 is protruded to be in contact engagement with the driving part 100, the driving part 100 can transmit the rotational driving force through the first rotary power receiving member C210 a. At this time, the pawls C211a at the top of the first rotary power receiving element C210a are in abutting engagement with the protrusions 101 of the driving member 100 to receive the rotary driving force from the driving member 100, and at the same time, the power transmitting portion C219a of the first rotary power receiving element C210a is immediately in abutting engagement with the force receiving post C259 of the hub C250 to transmit the rotary force to the hub C250, so that the power receiving port C210 as a whole and the hub C250 can rotate with the rotation of the driving member 100.
As shown in fig. 112 and 113, as the power receiving port C210 is rotated integrally, the second rotary power receiving member C210b, which is in abutment with the projecting end F111a of the stopper F111, is rotated to turn to the other side with respect to the rotational shaft of the hub C250 or the driving part 100, the second rotary power receiving member C210b is no longer in abutment with the projecting end F111a, and the first rotary power receiving member C210a is engaged with the driving part 100 in the previous projecting state, so that the first rotary power receiving member C210a does not form structural interference with the projecting end F111a of the stopper F111 after the rotation. Since the second rotary power receiving part C210b does not come into abutting interference with the protruding end F111a, the resilient element C279 at the bottom of the second rotary power receiving part C210b continues to release the resilient force to continue the outward extension of the second rotary power receiving part C210 b. Thus, the second rotary power receiver C210b can be brought into contact engagement with the driving member 100, and the pawls C211b of the second rotary power receiver C210b are brought into abutting engagement with the other projection 101 of the driving member 100 to receive the driving force of the rotation. After the second rotary power receiving part C210b is extended into contacting engagement with the driving part 100, the top of the inclined surface C216b of the second rotary power receiving part C210b also abuts the abutment surface C303 of the axial urging part C300 preventing excessive extension displacement of the second rotary power receiving part C210 b. Through the above-mentioned action cooperation, the power receiving port C210 is engaged with the driving member 100 as a whole, and finally, the power receiving port C210 transmits the rotational driving force to the rotating element (such as a photosensitive element, a developing element, etc.) in the process cartridge C through the hub to operate the rotating element, thereby participating in the developing operation.
When the user takes out the process cartridge C from the image forming apparatus after the power receiving port C210 is completely engaged with the driving part 100, the axial urging part C300 is caused to move backward in the direction-X relative to the boss C250 by the releasing action of the elastic force of the elastic member C279, without any further action of the external force.
Due to the randomness that the driving member 100 stops driving, the protrusion 101 of the driving member 100 drives the jaws C211a and C211b to stop rotating, the power receiving port C210 will take the following two states:
the first state: as shown in fig. 114 to 118, when the axial urging member C300 moves backward in the direction-X after the power receiving port C210 stops rotating, the inclined surface C302 of the axial urging member C300 may simultaneously act on the inclined surface C216a of the first rotating power receiving member C210a and the inclined surface C216b of the second rotating power receiving member C210b to retract the power receiving port C210 as a whole inward with respect to the hub C250. Since the overlapping engagement height H1 of the pawls C211a, C211b with the projection 101 is smaller than the distance H5 between the bottoms of the pawls C211a, C211b and the opposing face of the projecting end F111a, the power receiving port C210 is controlled to be disengaged from the driving member 100 by the inclined face C302 of the axial urging member C300 being pressed down to the inclined faces C216a, C216 b. In addition, even if the bottoms of the pawls C211a, C211b of the first and second rotary power receiving members C210a, C210b form abutting interference with the projecting end F111a of the stopper F111 during inward retraction, and cannot be further retracted axially inward, since the power receiving port C210 has been disengaged from the driving part 100, when the process cartridge C is taken out in the taking-out direction-X by the user, the inner edges C211a1, C211b1 of the pawls C211a, C211b do not form structural interference with the main body 102 of the driving part 100, that is, the pawls C211a, C211b do not form structural overlap with the main body 102 of the driving part 100 as viewed in the taking-out direction-X, so that the power receiving ports can move outward in accordance with the taking-out movement of the process cartridge C.
And a second state: as shown in fig. 119 to 121, when the axial urging member C300 moves backward in the direction-X after the power receiving port C210 stops rotating, due to the provision of the single rotary power receiving member in the power receiving port C210, the first rotary power receiving member C210a has a certain probability of being located forward in the mounting direction X of the process cartridge C with respect to the second rotary power receiving member C210b as the driving member 100 rotates, whereas the second rotary power receiving member C210b is located rearward, so that the inclined surface C302 thereof alone acts on the inclined surface C216a of the first rotary power receiving member C210a and retracts the first rotary power receiving member C210a inward when the axial urging member C300 moves backward in the direction-X, and the pawls C211a thereof disengage from the projections 101, so that the pawls C211a of the second rotary power receiving member C210a are higher than the pawls C211b of the first rotary power receiving member C210b as viewed from the side of the hub C250 under the control mechanism, whereas the pawl C211b of the second rotary power receiving part C210b protrudes further outward from the hub C250 than the pawl C211a of the first rotary power receiving part C210a, seen in the axial direction of the hub C250. However, during the inward retraction of the first rotary power receiving member C210a, the bottom of the pawls C211a come into abutting interference with the projecting ends F111a of the stoppers F111 so that the first rotary power receiving member C210a cannot be further retracted axially inward. In contrast to the above state one: just as the first rotary power receiving element C210a is located forward of the second rotary power receiving element C210b in the mounting direction X of the process cartridge C, when the user takes out the process cartridge C in the take-out direction-X, although the pawl C211a does not interfere with the projection 101 of the drive member 100 due to the inward retraction of the first rotary power receiving element C210a, when the first rotary power receiving element C210a moves in the direction-X, the inner edge of its pawl C211a comes into structural interference (overlapping area a) with the main body 102 of the drive member 100, i.e., the pawl C211a comes into structural overlap with the main body 102 of the drive member 100 as viewed in the take-out direction-X, so that it is difficult for the user to take out the process cartridge C from the image forming apparatus.
Therefore, when the power receiving opening of the process cartridge C is engaged with the driving member 100 in the second state, the power receiving opening can be displaced by the control member having one end thereof disposed on the end cap C290 so as to avoid the interference with the structure of the driving member 100.
As shown in fig. 122 and 123, in the second state, when the inclined surface C302 of the axial urging member C300 does not act on the inclined surface C216a of the first rotary power receiving member C210a, the displacement portion C215a of the first rotary power receiving member C210a does not contact with the other end C275a of the check member C275, and therefore, the first/second rotary power receiving member displacement portion C215a/C215b of the power receiving port C210 does not contact with the other end C275a of the check member C275 to affect the rotation thereof in the process of the contact engagement of the power receiving port C210 with the driving member 100 and the transmission of the rotational force. When the inclined surface C302 of the axial urging member C300 acts on the inclined surface C216a of the first rotary power receiving member C210a, the first rotary power receiving member C210 is pressed and retracted inwardly, the displacement portion C215a thereof comes into pressing abutment with the other end C275a of the check member C275 during the inward retraction, and since one end of the check member C275 is already fixed to the fixing portion C299 of the end cover C290, the other end C275a of the check member C275 exerts a resilient force upon the displacement portion C215a of the first rotary power receiving member C210 upon being pressed to displace and turn the first rotary power receiving member C210a, and the second rotary power receiving member C210b engaged with the first rotary power receiving member C210a is also displaced and turned in accordance therewith, that the entirety of the control member C210 is urged by the resilient force of the one end of the check member C275 to effect a partial turning in the counterclockwise direction, when the displacement portion C215a of the first rotary power receiving member C210a is turned with it and no longer comes into abutment with the other end C275a of the check member C275, the power receiving port C210 is no longer pushed to rotate as a whole.
As shown in FIG. 124, when the power receiving port C210 is rotated integrally, and viewed from the taking-out direction-X, under the action of the control member C275, one of the claws C211a1 is higher than the other claw C211b1, and the claws C211a1/C211b1 are not overlapped with the main body 102 of the driving member 100, so that when the power receiving port C210 moves along the direction-X, the inner edges C211a1/C211b1 of the claws C211a/C211b are not interfered with the main body 102 of the driving member 100, and thus the power receiving port C210 can be disengaged from the driving member 100. In addition, as shown in fig. 126, after the power receiving port C210 is pushed to rotate integrally, the inclined surface C216a/C216b also generates a rotational displacement along with the same, and the inclined surface C302 of the axial pushing component C300 can simultaneously exert a pressing action on the inclined surface C216a/C216b and control the inward retraction of the first rotating power receiving member C210a and the second rotating power receiving member C210b, thereby generating an auxiliary action on the disengagement of the power receiving port C210 and the driving component 100 integrally.
Finally, the power receiving port C910 in the second state can move outward with the removal of the process cartridge C after the whole process cartridge C is moved by the displacement.
In the above-described embodiment, the elastic member C279 may be a spring, a magnet, an elastic sponge, or the like.
In the above embodiment, the axial urging member C300 and the control member C275 may be provided separately or integrally.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
