[0031] In the following description, many specific details are explained in combination with the embodiments to facilitate a full understanding of the present invention, but it should be understood that the following embodiments and detailed descriptions are only for illustrative purposes and do not limit the scope of protection of the present invention.

[0032] Example 1

[0033] like Figure 2 and 3 As shown, the processing box 100 of the embodiment includes a first unit 10 and a second unit 20 combined with each other, the first unit 10 includes a first unit housing 11 and a photosensitive member 13 rotatably arranged in the first unit housing 11, and the second unit 20 includes a second unit housing 21 and a developing member (not visible in the figure) rotatably arranged in the second unit housing 21, the developing member is arranged opposite to the photosensitive member 13, and is used to transport unused toner stored in the second unit housing 21 toward the photosensitive member 13, so as to develop the electrostatic latent image formed on the surface of the photosensitive member 13.

[0034] The longitudinal end of the photosensitive member 13 is also provided with a first driving assembly for receiving and / or transmitting driving force, and the first driving assembly can be one component or two components. Figure 2 and 3 As shown, the first driving assembly includes a first driving force receiving member 15 for receiving driving force and a driving force transmitting member 14 for transmitting driving force. The first driving force receiving member 15 is used to receive driving force, and the driving force transmitting member 14 is used to transmit driving force to the developing member.

[0035] Along the axial direction of the photosensitive member 13 or the longitudinal direction Y of the process cartridge 100, the side provided with the first driving assembly is the driving side of the process cartridge 100, and the other side opposite to the driving side is the non-driving side. Figure 3 As shown, a guided portion 131 is provided at the longitudinal end of the process cartridge 100 located on the non-driving side, and the guided portion 131 is arranged to be movable along the longitudinal direction Y. In the process of installing the process cartridge 100 into the electrophotographic image forming apparatus, the guided portion 131 can move toward the inner direction of the process cartridge 100 when abutting against the locking member 200, so that the guided portion 131 can pass over the locking member 200 and continue to move along the guide rail H1012, thereby allowing the process cartridge to be installed in place.

[0036] Further, the guided portion 131 may be installed at the end of the photosensitive member 13 relative to the first driving force receiving member 15. Figure 4 and Figure 5 As shown, the end of the photosensitive member 13 is provided with a connecting sleeve 132, at least a portion of the connecting sleeve 132 extends into the interior of the photosensitive member 13, and the guided portion 131 is movably connected with the connecting sleeve 132 and can move along the axial direction of the photosensitive member 13. An elastic element 133 is provided between the guided portion 131 and the connecting sleeve 132, and the elastic element 133 is used to apply an elastic force to the guided portion 131 to move it toward the outside of the processing box. The elastic element 133 can be a spring, but is not limited thereto.

[0037] A guide groove 1321 is provided on the peripheral wall of the connecting sleeve 132, and the guided portion 131 has an elastic arm 1312 and a protrusion 1313 formed on the elastic arm 1312, and the protrusion 1313 is arranged in the guide groove 1321. Under the elastic force of the elastic element 133, a part of the guided portion 131 is located in the inner cavity of the connecting sleeve 132, and a part of the guided portion 131 extends out of the connecting sleeve 132 and can move along the guide rail H1012, and is supported and positioned by the guide rail H1012 when the processing cartridge is installed in place.

[0038] The guided portion 131 is provided with abutment surfaces 1311 on opposite sides of the processing box installation direction X. When the abutment surfaces 1311 abut against the locking member 200, the guided portion can move toward the inner direction of the processing box 100 to avoid the locking member 200, so that the guided portion 131 can pass over the locking member 200 and continue to move along the guide rail H1012, thereby allowing the processing box 100 to be smoothly installed and removed.

[0039] In Embodiment 1, the abutting surface 1311 is formed as an inclined surface or an arc surface that is tilted or has an angle relative to the installation direction X. As a variation, the guided portion 131 may be provided with a hemispherical abutting surface or an abutting surface of other shapes for abutting the locking member 200, as long as the guided portion 131 can be moved to avoid the abutting locking member 200.

[0040] Furthermore, in Example 1, the guided portion 131 can be made of a conductive material and configured to be electrically connected to an electronic photographic imaging device to transmit power to the photosensitive member 13 directly or indirectly through an intermediate conductive member, for example, the protrusion 1313 of the guided portion 131 contacts the photosensitive member 13 to transmit power to the photosensitive member 13.

[0041] As a variation of Embodiment 1, the guided portion 131 is configured to be elastically deformable, for example, by using an elastic arm structure. Specifically, when the guided portion 131 abuts against the locking member 200, it will be elastically deformed to avoid the locking member 200, so that the guided portion 131 can pass over the locking member 200 and continue to move along the guide rail H1012, thereby allowing the process cartridge to be smoothly installed in place or removed.

[0042] Example 2

[0043] like Figure 6 As shown, in Embodiment 2, the longitudinal end portion of the process cartridge 100 located on the non-driving side is provided with a guided portion 100E2 and an unlocking portion 202, and the unlocking portion 202 is arranged on the downstream side of the guided portion 100E2 in the installation direction X of the process cartridge. The unlocking portion 202 is used to move the locking member 200 to the unlocking position to allow the guided portion 100E2 to pass over the locking member 200 and continue to move along the guide rail H1012.

[0044] Further, the photosensitive member 13 is relative to the first driving force receiving member 15 (see Figure 2 ) is provided at the end portion thereof with a conductive member 201, which can be electrically connected to the electronic photographic imaging device to transmit power to the photosensitive member 13 directly or indirectly through an intermediate conductive member.

[0045] In Embodiment 2, the guided portion 100E2 can be disposed on the first unit housing 11 and is disposed to surround the conductive member 201. The guided portion 100E2 can be a circular, elliptical or polygonal structure, and the unlocking portion 202 can be directly connected to or disposed adjacent to the guided portion 100E2. Specifically, the unlocking portion 202 can be a roughly V-shaped structure, and its pointed end can be oriented toward the downstream side of the process cartridge installation direction X. In this way, during the installation of the process cartridge, the pointed end of the unlocking portion 202 can be inserted between the free end of the locking member 200 and the side wall of the guide rail H1012, and the locking member 200 can be pushed toward the unlocking position, and then the guided portion 100E2 will further push the locking member 200 away and continue to move along the guide rail H1012, so that the process cartridge can be smoothly installed in place.

[0046] Furthermore, in order to facilitate the removal of the processing box 100 from the electronic photographic imaging device, the processing box of Example 2 is also provided with an unlocking and holding mechanism, which is configured to keep the locking member 200 in the unlocking position to allow the guided portion 100E2 to withdraw from the guide rail H1012, so that the processing box can be smoothly removed.

[0047] Specifically, Figure 6As shown, the unlocking and holding mechanism in Embodiment 2 includes a transition portion 203 and a spring 204, the two ends of the transition portion 203 are connected to the spring 204 and the guided portion 100E2 respectively, and the end of the spring 204 away from the transition portion 203 is connected to the connecting portion 205, and the connecting portion 205 is arranged on the first unit housing 11. The arrangement of the transition portion 203 enables the locking member 200 to slide relatively from abutting against the guided portion 100E2 to abutting against the spring 204. That is, during the installation of the processing cartridge, after the guided portion 100E2 passes over the locking member 200, the transition portion 203 and the spring 204 will abut against the locking member 200 in sequence and slide relatively; in this process, the spring 204 can be deformed to adapt to the shape of the guide rail H1012. The spring 204 can be a tubular spring.

[0048] like Figure 7 As shown, after the process cartridge is installed in place, the spring 204 still abuts against the locking member 200 to keep the locking member 200 in the unlocked position. In this way, when the process cartridge 100 is taken out of the electrophotographic imaging device, the locking member 200 will sequentially contact and slide with the spring 204, the transition portion 203 and the guided portion 100E2, so that the guided portion 100E2 can be withdrawn from the guide rail H1012, ensuring that the process cartridge can be taken out smoothly.

[0049] For other descriptions of Example 2, please refer to Example 1 and will not be repeated here.

[0050] Example 3

[0051] like Figure 8 As shown, the difference between Embodiment 3 and Embodiment 2 is that in Embodiment 3, the spring 204 is replaced by an elastic tube or elastic rod 206 capable of elastic deformation. During the installation of the process cartridge, the elastic tube or elastic rod 206 can be deformed to match the shape of the guide rail H1012.

[0052] For other descriptions of Example 3, please refer to Example 1 and Example 2, which will not be repeated here.

[0053] Example 4

[0054] The difference between Example 4 and Example 2 lies in the different structural designs of the unlocking and holding mechanism.

[0055] Specifically, Fig. 9 and 10 As shown, the unlocking and holding mechanism in Example 4 includes a rocker arm 301 and a connecting rod 302; wherein, the first end of the rocker arm 301 is rotatably connected to the conductive member 201, and the second end of the rocker arm 301 forms a rotational sliding fit with the first end of the connecting rod 302; a connecting shaft 303 is provided on the first unit housing 11, and the second end of the connecting rod 302 forms a rotational sliding fit with the connecting shaft 303.

[0056] During the installation of the processing box, after the guided part 100E2 passes over the locking member 200, the locking member 200 will abut against the rocker arm 301 and the connecting rod 302 in turn and slide relatively; during this process, the shapes of the rocker arm 301 and the connecting rod 302 will change accordingly to adapt to the shape of the guide rail H1012.

[0057] like Fig.10 As shown, after the process cartridge is installed in place, the connecting rod 302 still abuts against the locking member 200 to keep the locking member 200 in the unlocked position. In this way, when the process cartridge 100 is taken out of the electrophotographic imaging device, the locking member 200 will sequentially contact and slide with the connecting rod 302, the swing arm 301 and the guided portion 100E2, so that the guided portion 100E2 can withdraw from the guide rail H1012, ensuring that the process cartridge can be taken out smoothly.

[0058] For other descriptions of Example 4, please refer to Example 1 and Example 2, which will not be repeated here.

[0059] Example 5

[0060] like Fig.11 As shown, in the process cartridge 100 of Embodiment 5, the conductive member 201 is located at the non-driving side of the process cartridge 100. Specifically, the conductive member 201 can be disposed at the end of the photosensitive member 13 and electrically connected to the photosensitive member 13. After the process cartridge is installed in place, the conductive member 201 can receive power from the electrophotographic imaging device.

[0061] In Embodiment 5, the conductive member 201 is arranged to move along the guide rail H1012 but is not directly or indirectly supported by the guide rail H1012. Furthermore, no guided portion supported and positioned by the guide rail H1012 is arranged on the outer periphery of the conductive member 201.

[0062] In order to enable the conductive member 201 to pass over the locking member 200, the process cartridge 100 of the fifth embodiment has a forced pushing portion 111, which is arranged on the non-driving side of the first unit housing 11. During the installation and removal of the process cartridge, the forced pushing portion 111 can abut against the locking member 200 to move the locking member 200 to the unlocking position, thereby allowing the conductive member 201 to move along the guide rail H1012 to a position electrically connected to the electrophotographic imaging device during the installation of the process cartridge 100, and allowing the conductive member 201 to withdraw from the guide rail H1012 during the removal of the process cartridge 100. The specific process of unlocking the locking member 200 using the forced pushing portion 111 can refer to the prior art, and will not be described in detail here.

[0063] Furthermore, if Fig.11 and 12As shown, the non-driving side of the process box 100 in Embodiment 5 may be provided with a guided portion 100E1 and a guided portion 21E1, which are guided and supported by corresponding guide rails in the electrophotographic imaging device. The guided portion 100E1 may be a convex column extending toward the outside of the process box 100 in the longitudinal direction Y of the process box, and the guided portion 21E1 may be located on the inner side of the guided portion 100E1 in the longitudinal direction Y of the process box.

[0064] The guided portion 21E1 may be provided on the second unit 20. Specifically, the second unit 20 includes a second unit non-driving side terminal piece 21E located on the non-driving side of the processing cartridge 100, and the second unit non-driving side terminal piece 21E is formed integrally or separately with the second unit housing 21. When the second unit non-driving side terminal piece 21E is in the form of a separate body, the second unit non-driving side terminal piece 21E will be combined with the second unit housing 21 in the form of an end cap. The guided portion 21E1 may be a part of the non-driving side terminal piece 21E, or a contact piece mounted on the non-driving side terminal piece 21E. Preferably, at least a part of the guided portion 21E1 faces the rear of the mounting direction X; along the longitudinal direction Y, the guided portion 21E1 does not protrude from the second unit non-driving side terminal piece 21E, so that it is not easily broken.

[0065] Furthermore, the non-driving side of the process cartridge 100 is provided with both the guided portion 100E1 and the guided portion 21E1, so that the process cartridge 100 can be stably supported.

[0066] For other descriptions of Example 5, please refer to Example 1 and will not be repeated here.

[0067] Example 6

[0068] like Fig.13 As shown, the difference between the embodiment 6 and the embodiment 5 is that the conductive member 201 in the embodiment 6 is an elastic conductive member, and the elastic conductive member 201 can produce elastic deformation to pass over the locking member 200 when it abuts against the locking member 200, so as to continue to move along the guide rail H1012 to allow the processing box 100 to be installed in place and taken out smoothly. In other words, the embodiment 6 does not need to set the forced pushing portion 111 as in the embodiment 5, so as to simplify the structure of the processing box.

[0069] Specifically, the conductive member 201 may have two arc-shaped conductive sheets, and during the installation and removal of the process cartridge, the arc-shaped conductive sheets are elastically deformed when they abut against the locking member 200 to avoid the locking member 200. As a variation, the conductive member 201 may also have only a single arc-shaped conductive sheet.

[0070] Similar to the fifth embodiment, although the conductive member 201 in the sixth embodiment is arranged to move along the guide rail H1012, it is also not directly or indirectly supported by the guide rail H1012, and the outer periphery of the conductive member 201 is not provided with a guided portion 100E2 supported and positioned by the guide rail H1012.

[0071] For other descriptions of Example 6, please refer to Example 1 and Example 5, which will not be repeated here.

[0072] It should be noted that, unless there are any contradictions or exclusions, the different embodiments disclosed above may be quoted, referenced or combined with each other, and the technical features / components of different embodiments may also be combined and / or replaced with each other.

[0073] Although the present invention is described above through embodiments, it should be understood that the above embodiments are only used to exemplarily describe the feasible implementation methods of the present invention, and should not be interpreted as limiting the protection scope of the present invention. That is, any replacement or change made by those skilled in the art in accordance with the present invention should also be covered by the protection scope of the claims of the present invention.
