[0046] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0047] In the prior art, when the image forming device 20 needs to replace the processing box 10, the electrical connection between the processing box 10 and the image forming device 20 and the clutch of the drive connection need to be operated separately, which is cumbersome and the structures of the processing box 10 and the image forming device 20 are relatively complex.

[0048] In order to simplify the structure of the processing box 10 and the image forming device 20 and improve the operating performance. Figures 5 to 9As shown, the present invention provides a process cartridge 10 that can be detachably mounted on an image forming device 20. The process cartridge 10 has a first end and a second end along a first direction D1. In a feasible embodiment, the first direction D1 is the length direction of the process cartridge 10. The first end of the process cartridge 10 has an electrical contact portion 11 and a drive mating portion 12. The second end of the process cartridge 10 has a force-bearing portion 13, wherein:

[0049] The electrical contact portion 11 is used to directly or indirectly achieve electrical connection with the main body side electrical contact point 22 in the image forming device 20. When the electrical contact portion 11 is in direct contact with the main body side electrical contact point 22, the electrical contact portion 11 and the main body side electrical contact point 22 are directly electrically connected. When the electrical contact portion 11 and the main body side electrical contact point 22 are electrically connected through components such as springs mentioned later, the electrical contact portion 11 and the main body side electrical contact point 22 are indirectly electrically connected. The drive mating portion 12 is used to achieve drive mating with the drive portion 23 in the image forming device 20.

[0050] When the processing box 10 is installed to the image forming device 20, the processing box 10 may have a first position and a second position. When the force-bearing part 13 is subjected to external force or the external force received exceeds a threshold value, the processing box 10 can move from the second position to the first position along the first direction D1. When the external force received by the force-bearing part 13 disappears or the external force received is lower than the threshold value, the processing box 10 can move from the first position to the second position along the first direction D1.

[0051] When the processing box 10 is located at the first end of the moving path (such as the first position mentioned above), the electrical contact part 11 is directly or indirectly electrically connected to the main body side electrical contact point 22 in the image forming device 20, and the drive matching part 12 is drive matched with the drive part 23 in the image forming device 20; when the processing box 10 is located at the first end of the moving path (such as the second position mentioned above), the electrical contact part 11 is disconnected from the electrical connection with the main body side electrical contact point 22 in the image forming device 20, and the drive matching part 12 is disconnected from the drive matching with the drive part 23 in the image forming device 20.

[0052] By arranging the electrical contact portion 11 and the drive mating portion 12 on the same side of the processing box 10, when the processing box 10 is replaced, the electrical contact portion 11 and the electrical contact on the main body side can be disengaged, and the drive mating portion 12 and the drive portion 23 can be disengaged at the same time, which is convenient for operation and can simplify the structure of the processing box 10 and the image forming device 20.

[0053] The process cartridge 10 also includes some conventional functional components that require high-voltage power supply (such as a charging roller, a developing roller, etc.) and consumable chips for storing information. Preferably, the electrical contact portion 11 includes a high-voltage electrical contact for providing high voltage to the process cartridge 10 or a chip electrical contact for providing low voltage to the consumable chips in the process cartridge 10. Two electrical contact portions 11 may be provided, and the two electrical contact portions 11 are arranged on opposite sides of the bottom of the first end of the process cartridge 10 to avoid interference with the drive mating portion 12. This can also increase the contact area between the electrical contact portion 11 and the main body-side electrical contact point 22, thereby improving the electrical connection effect.

[0054] In a feasible embodiment, referring to Figure 6 as well as Figure 7 As shown, the electrical contact portion 11 includes a conductive elastic member 111 and a box-side electrical contact point 112. The conductive elastic member 111 has both conductive and reset functions. After the processing box 10 is installed in the image forming device 20, the conductive elastic member 111 contacts the box-side electrical contact point 112 and the body-side electrical contact point 22 respectively to achieve electrical connection. When it is necessary to separate the conductive elastic member 111 from the body-side electrical contact point 22, the conductive elastic member 111 can also provide a reset force to the processing box 10 along the first direction D1 from the first position to the second position, so that the box-side electrical contact point 112 can be electrically disconnected from the body-side electrical contact point 22.

[0055] In another possible way, refer to Figure 8 as well as Figure 9 As shown, the electrical contact portion 11 includes a cartridge-side electrical contact 112, to which a first elastic return member 113 is connected. The cartridge-side electrical contact 112 does not have a reset function and requires at least one first elastic return member 113 to perform the reset function of the process cartridge 10. After the process cartridge 10 is installed in the image forming apparatus 20, the cartridge-side electrical contact 112 is electrically connected to the body-side electrical contact 22. When the cartridge-side electrical contact 112 and the body-side electrical contact 22 need to be separated, the first elastic return member 113 can provide a reset force to the process cartridge 10 along the first direction D1 from the first position to the second position, thereby disconnecting the electrical contact portion 11 from the body-side electrical contact 22. Of course, in another feasible embodiment, the first elastic return member can be provided at any position on the first end of the process cartridge 10, as long as it can reset the process cartridge 10.

[0056] Based on the process cartridge 10 provided in the above embodiment, Figures 1 to 19As shown, the utility model provides an image forming device 20, including a mounting portion 21, the mounting portion 21 is used for detachably mounting a processing box 10, the processing box 10 has a first end and a second end along a first direction D1, the first end of the processing box 10 has an electrical contact portion 11 and a drive mating portion 12; the second end of the processing box has a force-bearing portion 13.

[0057] Reference Figure 5 As shown, the mounting portion 21 has a first side and a second side along a first direction D1 (i.e., the length direction of the processing box 10), and a main body side electrical contact point 22 and a driving portion 23 are provided on the first side of the mounting portion 21. When the processing box 10 is installed in the image forming device 20, the first side of the mounting portion 21 is opposite to the first end of the processing box 10, and a force-applying member 24 is provided on the second side of the mounting portion 21. The force-applying member 24 can move along a preset trajectory, and the second end of the processing box 10 is located on the preset trajectory. When the force-applying member 24 moves along the preset trajectory, it can be offset from the force-bearing portion 13 of the processing box 10. During the movement of the force-applying member 24, the processing box 10 is driven to move along the first direction D1. After the force-applying member 24 moves to the end of the preset trajectory, the processing box 10 can be maintained at the first end of the moving path. When the force-applying member 24 moves back along the preset trajectory, the processing box 10 can also return to the second end of the moving path under the action of external force.

[0058] When the processing box 10 is located at the first end of the moving path, the electrical contact part 11 is directly or indirectly electrically connected to the electrical contact point 22 on the main body side. At the same time, the driving matching part 12 is driven by the driving part 23. The driving part 23 can drive the components in the processing box 10 to work and print the image.

[0059] When the processing box 10 is located at the second end of the moving path, the electrical contact part 11 is disconnected from the main body side electrical contact point 22, and the driving mating part 12 is disconnected from the driving part 23, so that the processing box 10 can be taken out of the image forming device 20.

[0060] By providing an electrical contact portion 11 and a drive mating portion 12 at the first end of the processing box 10, providing a force-bearing portion 13 at the second end of the processing box 10, and providing a main body side electrical contact point 22 and a drive portion 23 on the first side of the mounting portion 21 of the image forming device 20, a force-applying member 24 on the second side of the mounting portion 21 is used to apply force to the force-bearing portion 13 of the processing box 10 to drive the processing box 10 to move along the first direction D1 toward the first side close to the mounting portion. Only the force-applying member 24 needs to be operated to achieve the engagement and disengagement of the electrical contact portion 11 and the main body side electrical contact point 22, as well as the engagement and disengagement of the drive mating portion 12 and the drive portion 23, thereby simplifying the image forming device structure 20 while having higher reliability and operability.

[0061] In a feasible embodiment, referring to Figure 13 、 Figure 18as well as Figure 19 As shown, the force-applying member 24 includes a swing arm 241 and a driving rod 242. The swing arm 241 is pivotally connected to the mounting portion 21. The driving rod 242 is connected to the swing arm 241. The driving rod 242 can drive the swing arm 241 to move along a preset trajectory. The preset trajectory is a rotation trajectory centered on the pivot axis. The swing arm 241 rotates around the pivot axis to apply force to the processing box 10.

[0062] In the initial state, the processing box 10 is located at the second end of the moving path. During the rotation of the swing arm 241, the swing arm 241 rotates to abut against the force-bearing part 13 of the processing box 10. The driving rod 242 drives the swing arm 241 to rotate continuously, so that the swing arm 241 pushes the processing box 10 to move along the first direction D1. When the electrical contact part 11 is electrically connected with the electrical contact point 22 on the main body side, and the driving mating part 12 is driven by the driving part 23, the swing arm 241 stops rotating and keeps the processing box 10 at the first end of the moving path. After the swing arm 241 rotates in the opposite direction, the processing box 10 can return to the second end of the moving path.

[0063] When the electrical contact portion 11 of the process cartridge 10 does not have a reset function, in order to enable the process cartridge 10 to smoothly return to the second end of the moving path, in the embodiment provided by the present application, reference is made to Figure 13 as well as Figure 18 As shown, the first side of the mounting portion 21 has a second elastic recovery member 25, and the second elastic recovery member 25 is connected to the first end of the processing box 10. When the processing box 10 moves toward the first end of the moving path, the second elastic recovery member 25 undergoes elastic deformation and accumulates elastic recovery force. When it is necessary to disconnect the electrical connection and drive cooperation between the processing box 10 and the image forming device 20, the swing arm 241 rotates in the opposite direction, and the elastic recovery force of the second elastic recovery member 25 is released, driving the processing box 10 to move toward the second end of the moving path.

[0064] In a feasible embodiment, the second elastic return member 25 includes a spring. When the processing box 10 is located at the first end of the moving path, the opposite ends of the spring are respectively in contact with the first side of the mounting portion 21 and the first end of the processing box 10. During the movement of the processing box 10 toward the first end of the moving path, the spring is compressed and accumulates elastic return force. When the processing box 10 needs to be replaced, the elastic return force of the spring is released, thereby driving the processing box 10 to move toward the second end of the moving path.

[0065] Furthermore, the spring is made of a conductive material, thereby realizing electrical connection between the main body side electrical contact point 22 and the electrical contact portion 11. When the processing box 10 is located at the first end of the moving path, the opposite ends of the spring respectively abut against the main body side electrical contact point 22 and the electrical contact portion 11. Since the spring is conductive, even if the main body side electrical contact point 22 and the electrical contact portion 11 fail to contact and connect, electrical connection between the two can still be achieved, so that the image forming device 20 can operate normally.

[0066] The embodiments provided by the present invention refer to Figure 10 As shown, a processing box drawer 26 is provided in the mounting portion 21, and the processing box 10 is provided in the processing box drawer 26. Since the second elastic recovery member 25 is in direct contact with the electrical contact portion 11, in order to prevent the second elastic recovery member 25 from scratching and damaging the electrical contact portion 11 during the process of the processing box drawer 26 being separated from the mounting portion 21, a guide matching portion 261 is provided on the processing box drawer 26, and a guide portion 27 is provided on the first side of the mounting portion 21. When the processing box drawer 26 moves along the second direction D2, a guide matching portion 261 is formed with the guide portion 27, so that the processing box drawer 26 can move in the first direction D1 toward the second side of the mounting portion 21.

[0067] The second direction D2 is perpendicular to the first direction D1. The second direction D2 is the direction in which the processing box drawer 26 is pulled out from the mounting portion 21, that is, the width direction of the processing box 10. Under the cooperation of the guide matching portion 261 and the guide portion 27, the processing box drawer 26 moves along the first direction D1 toward the second side of the mounting portion 21, thereby driving the processing box 10 on the processing box drawer 26 to move toward the second side of the mounting portion 21, so that the first end of the processing box 10 is away from the second elastic recovery member 25, thereby effectively preventing the elastic recovery force of the second elastic recovery member 25 from being unable to completely push the electrical contact portion 11 away from the second elastic recovery member 25. When the processing box drawer 26 is extracted, the continuous contact between the electrical contact portion 11 and the second elastic recovery member 25 causes friction damage.

[0068] In a feasible embodiment, the guide portion 27 includes a guide protrusion, and the guide matching portion 261 includes a guide slope. When the processing box drawer 26 moves along the second direction D2 toward the outside of the mounting portion 21, the guide protrusion abuts against the guide slope. As the processing box drawer 26 continues to move, the guide protrusion applies a force in the first direction D1 to the guide slope, so that the processing box drawer 26 moves along the first direction D1 toward the second side of the mounting portion 21, thereby realizing that the first end of the processing box 10 is away from the second elastic return member 25.

[0069] Preferably, reference Figure 11 as well as Figure 12As shown, a mounting plate 29 is provided on the first side of the mounting portion 21. The mounting plate 29 includes a first plate 291 and a second plate 292. The first plate 291 is fixed to the first side of the mounting portion 21. The first plate 291 and the second plate 292 are perpendicular to each other. The second plate 292 extends along the second direction D2. A guide protrusion is provided on the open end of the first plate 291 near the mounting portion 21. The surface of the first plate 291 facing the process cartridge 10 is provided with a plurality of latches 293 for securing the mounting plate 29 to the image forming device 20. The mounting position can be adaptively adjusted according to the position of the process cartridge drawer 26.

[0070] Reference Figure 2 As shown, the image forming device 20 is pivotally connected to a front door 28 at the opening of the mounting portion 21 , and the end of the driving rod 242 away from the swing arm 241 is connected to the front door 28 , thereby realizing the linkage between the front door 28 and the force applying member 24 , wherein:

[0071] When the front door 28 is closed, the front door 28 is rotated so that the driving rod 242 drives the swing arm 241 to rotate until it abuts against the force-bearing part 13 of the processing box 10, and continues to push the processing box 10 to move toward the first end of the moving path. When the front door 28 is completely closed, the electrical contact point 22 on the main body side is electrically connected to the electrical contact part 11, the driving matching part 12 and the driving part 23 achieve driving matching, and the swing arm 241 and the force-bearing part 13 of the processing box 10 still maintain an abutting state.

[0072] When the front door 28 is opened, the driving rod 242 drives the swing arm 241 to rotate to a state where the swing arm 241 is released from the force-bearing part 13 of the processing box 10. After the swing arm 241 is disengaged from the force-bearing part 13 of the processing box 10, the processing box 10 moves toward the second end of the moving path under the action of the elastic restoring force applied by the second elastic restoring member 25.

[0073] Based on the above embodiments, refer to Figures 13 to 16 As shown, when the electrical contact portion 11 of the process cartridge 10 does not have a reset function, the working process of installing the process cartridge 10 in the image forming apparatus 20 of the present application is as follows:

[0074] First, multiple processing boxes 10 are fixed in the processing box drawer 26, and then the processing box drawer 26 is moved from the opening of the mounting portion 21 along the second direction D2 to the mounting portion 21. After the processing box drawer 26 is installed in the mounting portion 21, the front door 28 is rotated so that the driving rod 242 drives the swing arm 241 to rotate until it abuts against the force-bearing portion 13 of the processing box 10. As the front door 28 continues to rotate, the swing arm 241 continuously applies a force in the first direction D1 to the force-bearing portion 13, so that the processing box 10 moves toward the first end of the moving path. During the movement, the second elastic return member 25 is compressed to accumulate elastic return force; when the front door 28 is completely closed, the electrical contact point 22 on the main body side is electrically connected to the electrical contact portion 11, and at the same time, the driving mating portion 12 is driven to cooperate with the driving portion 23. At this time, the swing arm 241 and the second end of the processing box 10 still remain in a state of abutment.

[0075] When the processing box 10 needs to be replaced, the front door 28 is opened. Under the action of the driving rod 242, the swing arm 241 rotates to disengage from the second end of the processing box 10, that is, the state of resistance is released. The elastic restoring force accumulated in the second elastic restoring member 25 acts on the processing box 10, driving the processing box 10 to move along the first direction D1 toward the second end of the moving path. After the front door 28 is fully opened, the processing box 10 reaches the second end of the moving path. At this time, the processing box drawer 26 can be taken out from the mounting portion 21, and then the processing box 10 can be replaced.

[0076] During the movement of the processing box drawer 26, under the guidance and cooperation of the guide portion 27 of the mounting portion 21 and the guide cooperation portion 261 of the processing box drawer 26, the processing box drawer 26 moves along the first direction D1 toward the second side of the mounting portion 21, thereby driving the first end of the processing box 10 away from the second elastic return member 25 on the first side of the mounting portion 21, thereby avoiding friction damage caused by continuous contact between the electrical contact portion 11 and the second elastic return member 25.

[0077] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
