[0063] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0064] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0065] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "fixed," and the like should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections, or communication between them; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0066] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples described in this specification without mutual contradiction.

[0068] In the related art, during the separation process of the chip in the powder cartridge and the spring contact of the main body, the chip and the spring contact slide against each other, causing wear on the chip contacts and shortening the chip's lifespan. The inventors have discovered that this problem occurs because during the separation process of the chip in the powder cartridge and the spring contact of the main body, the chip and the spring contact slide against each other, generating sliding friction between the chip and the spring contact, which wears the chip contacts and shortens the chip's lifespan.

[0069] In order to solve the above problems, an embodiment of the present invention provides a processing box, a processing box group and an image forming device, in which the chip is separated from the spring along the width direction of the body, thereby preventing the contacts of the chip and the spring from sliding against each other, thereby reducing the wear on the contacts on the chip and improving the life of the chip.

[0070] The following describes in detail the process cartridge, process cartridge assembly, and image forming apparatus provided by the embodiments of the present invention in conjunction with specific embodiments.

[0071] like Figures 1 to 3 As shown, an embodiment of the present invention provides an image forming apparatus, including a body 10 , a drawer 20 and a processing box 30 .

[0072] The main body 10 is provided with a spring (not shown in the figure). Figure 1 and Figure 2As shown, the length direction of the body 10 is the X-axis direction, the width direction of the body 10 is the Y-axis direction, and the height direction of the body 10 is the Z-axis direction. The X-axis, Y-axis and Z-axis are perpendicular to each other.

[0073] The drawer 20 is used to accommodate the processing cartridge 30. The drawer 20 can be inserted into the body 10 and can also be pulled out from the body 10. In some examples, the insertion direction of the drawer 20 is along the +X axis direction, and the pulling direction of the drawer 20 is along the -X axis direction.

[0074] The drawer 20 is provided with a driving assembly, and the driving assembly is configured to move under the action of the body 10 when the drawer 20 is inserted into the body 10 .

[0075] The processing cartridge 30 is housed in the drawer 20. The drawer 20 may house one processing cartridge 30 or multiple processing cartridges 30. In some examples, see Figure 3 As shown, the drawer 20 can accommodate four processing boxes 30. The four processing boxes 30 are arranged in sequence along the length direction of the body 10. The four processing boxes 30 are arranged in sequence along the length direction of the body 10 and accommodated in the drawer 20. The four processing boxes 30 form a processing box group.

[0076] The processing box 30 provided in the embodiment of the present invention includes a box body 31 (see Figure 5 As shown), the telescopic component and the chip 32, the telescopic component is installed on the box body 31, and the chip 32 is set on the telescopic component.

[0077] The telescopic assembly is configured such that, when the drawer 20 is inserted into the body 10, the drive assembly drives the chip 32 to move along the width of the body 10. The chip 32 moves to a first position, thereby electrically connecting the spring clip on the chip 32 with the body 10. Specifically, when the drawer 20 is inserted into the body 10, the drive assembly moves under the force of the body 10, driving the telescopic assembly, which drives the chip 32 to move along the width of the body 10. The chip 32 moves to the first position, electrically connecting the contacts of the chip 32 and the spring clip on the body 10, thereby enabling communication between the body 10 and the chip 32.

[0078] It should be noted that when the chip 32 is electrically connected to the contacts of the spring of the body 10 (see Figure 7 and Figure 12 As shown), the position of the chip 32 relative to the box body 31 is the first position.

[0079] When the drawer 20 is not inserted into the body 10, there is a gap between the chip 32 and the spring of the body 10 in the width direction of the body 10. Figure 3 and Figure 9As shown), the position of the chip 32 relative to the box body 31 is the second position, that is, when the chip 32 is in the initial state, the position of the chip 32 relative to the box body 31 is the second position.

[0080] When the drawer 20 is inserted into the main body 10 and the chip 32 is engaged with the contacts of the spring clip on the main body 10, the chip 32 moves along the width direction of the main body 10 and toward the spring clip of the main body 10 under the drive of the telescopic component, which can prevent the chip 32 from sliding against the contacts of the spring clip in the length direction of the main body 10, thereby reducing the wear on the contacts on the chip 32 and improving the life of the chip 32.

[0081] When the drawer 20 is pulled out of the body 10 , the chip 32 moves to the second position along the width direction of the body 10 , so that the chip 32 is separated from the elastic piece.

[0082] During the separation process of the chip 32 and the spring clip of the main body 10, the chip 32 is driven by the telescopic component to move away from the spring clip of the main body 10 along the width direction of the main body 10, and the chip 32 moves to the second position, so that the chip 32 is separated from the spring clip, which can prevent the chip 32 from sliding against the spring clip contact in the length direction of the main body 10, thereby reducing the wear on the contacts on the chip 32 and improving the life of the chip 32.

[0083] It should be noted that when the drawer 20 is pulled out from the body 10, the telescopic assembly can move the chip 32 under its own force or under the action of an external force. In this embodiment, when the drawer 20 is pulled out from the body 10, the telescopic assembly drives the chip 32 under its own force, causing the chip 32 to move along the width direction of the body 10 to the second position.

[0084] In one possible implementation, see Figure 2 As shown, the driving assembly includes a driving member 21, a third reset member 22 and at least one toggle member 23, the toggle member 23 is rotationally connected to the drawer 20, the driving member 21 is fixedly connected to the toggle member 23, and the third reset member 22 is connected between the driving member 21 and the drawer 20.

[0085] Exemplarily, there are multiple toggling members 23 , each of which is rotatably connected to the drawer 20 , and the driving member 21 is fixedly connected to the multiple toggling members 23 .

[0086] The driving member 21 may be a driving rod, a driving block, a driving plate, etc., and is not specifically limited here.

[0087] The driving member 21 is configured to abut against the main body 10 when the drawer 20 is inserted into the main body 10 and drive the plurality of toggles 23 to move, so that the plurality of toggles 23 respectively drive the telescopic assembly of one processing box 30 .

[0088] The driving member 21 is located on one side of the drawer 20 in the width direction of the body 10, and the driving member 21 extends along the length direction of the body 10. Figure 5 and Figure 6 As shown, when the drawer 20 is inserted into the main body 10, the driving member 21 abuts against the main body 10 at one end in the +X axis direction. As the drawer 20 is inserted into the main body 10, the driving member 21 moves along the -X axis direction under the pressure of the main body 10 because the main body 10 is fixed.

[0089] The third restoring member 22 is used to drive the driving member 21 to return to its initial state when the drawer 20 is pulled out from the body 10 .

[0090] See also Figure 3 As shown, when the drawer 20 is not inserted into the body 10 , the state of the driving member 21 is the initial state of the driving member 21 .

[0091] The third reset member 22 may be an elastic member. In this embodiment, the third reset member 22 may be a tension spring.

[0092] See also Figure 3 As shown, when the drawer 20 is not inserted into the body 10 , the state of the third restoring member 22 is the initial state of the third restoring member 22 .

[0093] The toggle member 23 may be a toggle rod, a toggle block, a toggle plate, etc., and is not specifically limited here.

[0094] See also Figure 3 As shown, when the drawer 20 is not inserted into the body 10 , the state of the toggle member 23 is the initial state of the toggle member 23 .

[0095] The plurality of toggles 23 are located on one side of the drawer 20 in the width direction of the body 10 . The driving member 21 and the plurality of toggles 23 are located on the same side of the drawer 20 in the width direction of the body 10 .

[0096] The number of the toggle members 23 is equal to the number of the process cartridges 30. Each toggle member 23 corresponds to a telescopic assembly of a process cartridge 30. Each toggle member 23 is provided with a rotating shaft 231 (see FIG. Figure 4 As shown), the rotating shaft 231 is rotatably connected to the drawer 20.

[0097] See 5 and Figure 6As shown, when the drawer 20 is inserted into the body 10, one end of the driving member 21 in the +X axis direction contacts the body 10. Under the pressure of the body 10, the driving member 21 moves along the -X axis direction, and the driving member 21 drives the multiple toggle members 23 to rotate clockwise. That is, each toggle member 23 rotates along the +W direction until each toggle member 23 contacts the corresponding telescopic component of the processing cartridge 30. Figure 7 and Figure 8 As shown, the driving member 21 continues to move along the -X axis direction, and multiple toggle members 23 respectively drive the telescopic components of a processing box 30. Each telescopic component drives the chip 32 to move along the width direction of the main body 10. Each chip 32 moves to the first position, which can electrically connect the chip 32 with the contacts of the spring of the main body 10.

[0098] When the drawer 20 is pulled out from the main body 10, the driving member 21 is disengaged from the main body 10 at one end in the +X axis direction, and the driving member 21 is restored to the initial state of the driving member 21 under the action of the elastic force of the third reset member 22. During the process of the driving member 21 returning to the initial state of the driving member 21, the driving member 21 moves along the +X axis direction, and the driving member 21 drives the multiple toggle members 23 to rotate counterclockwise, that is, each toggle member 23 rotates along the -W direction, and the multiple toggle members 23 are respectively disengaged from the telescopic components of the corresponding processing box 30.

[0099] It should be noted that, when the driving member 21 is in the initial state, the third restoring member 22 and the toggle member 23 are respectively in their respective initial states.

[0100] In one possible implementation, see Figure 3 、 Figure 5 、 Figure 9 and Figure 10 As shown, the telescopic assembly includes a chip holder 33, a rotating block 34 and a movable block 35. The chip holder 33 is connected to the box body 31. The chip holder 33 has an active space. The rotating block 34, the movable block 35 and the chip 32 are arranged in the active space in sequence along the width direction of the main body 10. The toggle member 23 can drive the rotating block 34 to rotate. The rotating block 34 can drive the chip 32 to move along the width direction of the main body 10 through the movable block 35, and the chip 32 moves to the first position.

[0101] The chip holder 33 is located on one side of the box body 31 in the width direction of the main body 10 .

[0102] The chip holder 33 can be fixed to the box body 31 by welding, bonding or clamping.

[0103] The chip holder 33 is provided with an opening 332 on one side in the width direction of the body 10 (see Figure 9As shown), that is, the chip holder 33 is provided with an opening 332 on one side in the +Y axis direction, and the opening 332 is communicated with the activity space.

[0104] See also Figure 9 、 Figure 10 and Figure 11 As shown, the rotating block 34 has a driven portion 341 exposed outside the chip holder 33. The driven portion 341 can be a driven block, a driven rod or a driven plate, etc., without specific limitation.

[0105] The rotating block 34 further includes a rotating body 342, which is connected to the driven portion 341. The rotating body 342 and the driven portion 341 can be integrally formed or connected together by welding or bonding.

[0106] The rotating body 342 is located in the movable space of the chip holder 33 .

[0107] The chip holder 33 is provided with an escape hole 331 (see Figure 9 As shown in FIG. 3 , the driven portion 341 passes through the avoidance hole 331. When the drawer 20 is inserted into the body 10, the toggle member 23 rotates clockwise until it abuts against the driven portion 341, and can cause the driven portion 341 to rotate counterclockwise, thereby causing the rotating block 34 to rotate counterclockwise.

[0108] See also Figure 11 As shown, the rotating block 34 is provided with an engagement surface 343 and a driving surface 344. The engagement surface 343 and the driving surface 344 are located on the rotating body 342. The driving surface 344 is connected to the edge of the engagement surface 343. The engagement surface 343 is a flat surface, while the driving surface 344 is an arcuate surface. The driving surface 344 has a first driving position 3441 and a second driving position 3442 in the width direction of the body 10. The second driving position 3442 is closer to the chip 32 than the first driving position 3441 in the width direction of the body 10.

[0109] See also Figure 9 and Figure 10 As shown, when the drawer 20 is not inserted into the body 10 , the state of the rotating block 34 is the initial state of the rotating block 34 , the state of the movable block 35 is the initial state of the movable block 35 , and the state of the chip 32 is the initial state of the chip 32 .

[0110] See also Figure 12 As shown, the movable block 35 has a first mating surface 351a mating with the engagement surface 343 and a second mating surface 351b mating with the driving surface 344 . The first mating surface 351a is flat, and the second mating surface 351b is an arcuate surface.

[0111] When the chip 32 is in the initial state, the first mating surface 351 a is parallel to the bonding surface 343 , the first mating surface 351 a is engaged with the bonding surface 343 , and the second mating surface 351 b is not in contact with the driving surface 344 .

[0112] See also Figure 13 and Figure 14 As shown, when the rotating block 34 rotates counterclockwise, the driving surface 344 contacts the second mating surface 351b, and the first driving position 3441 of the rotating block 34 first contacts the second mating surface 351b of the movable block 35. The rotating block 34 continues to rotate until the second driving position 3442 contacts the second mating surface 351b of the movable block 35. At this time, the chip 32 is electrically connected to the spring clip of the main body 10.

[0123] When the drawer 20 is pulled out of the body 10, the driving member 21 is disengaged from the body 10 at one end in the +X-axis direction. The driving member 21 is restored to its initial state under the elastic force of the third return member 22. During the process of returning to its initial state, the driving member 21 moves along the +X-axis direction, driving the plurality of toggles 23 to rotate counterclockwise. The plurality of toggles 23 are respectively disengaged from the driven portions 341 of the rotating block 34 of the telescopic assembly of the corresponding process cartridge 30. The rotating block 34 is restored to its initial state under the elastic force of the first return member 36. The rotating block 34 is disengaged from the movable block 35. The movable block 35 moves along the -Y-axis direction under the elastic force of the second return member 37 and is restored to its initial state. At this time, the first mating surface 351a is engaged with the engagement surface 343. When the movable block 35 moves along the -Y axis direction, the movable block 35 will apply a pulling force to the chip 32, and the spring piece of the main body 10 will apply a pushing force to the chip 32, so that the chip 32 moves along the -Y axis direction, so that the chip 32 returns to the initial state of the chip 32 along the width direction of the main body 10, thereby separating the chip 32 from the spring piece.
