[0087] Figure 32B This is a schematic diagram of the developing cartridge involved in this utility model when it is installed; Figure 2A and Figure 2B This is a partial structural schematic diagram of the imaging device involved in this utility model; Figure 2A and Figure 2B This is a perspective view of the developing cartridge involved in this utility model.

[0088] like Figure 32A , Figure 32B and Figure 33A As shown, the developing cartridge 100 and the drum unit 900 are combined and installed together in the imaging device, or the developing cartridge 100 is directly installed in the imaging device. The developing cartridge 100 is provided with a chip, which is used to electrically connect / make contact with the electrical contact 004 provided in the imaging device, so as to establish a communication connection between the developing cartridge 100 and the imaging device. Furthermore, the electrical connection / contact between the chip and the electrical contact 004 can be a direct electrical connection / contact, or it can be an indirect electrical connection / contact through a conductive connector that makes electrical connection / contact with the chip and the electrical contact 004. Furthermore, the side wall 001 in the imaging device is located on one side of the developing cartridge 100, and the upper wall 002 and the lower wall 003 in the imaging device are arranged opposite to each other. The electrical contact 004 is provided on the upper wall 002.

[0089] To make the description clearer and more accurate, Figure 33B and Figure 33A Based on the state shown, the developing cartridge 100 has a first direction, a second direction, and a third direction. Specifically, the length direction / left-right direction of the developing cartridge 100 is defined as the first direction, the second direction / front-back direction intersects with the first direction, the developing cartridge 100 is installed and removed along the second direction, and the third direction / up-down direction intersects with the first direction and the second direction respectively. Preferably, the first direction, the second direction, and the third direction are perpendicular to each other.

[0090] like Figure 33B and Figure 34AAs shown, the developing cartridge 100 includes a housing 1 for containing developer and a developing element 11 rotatably disposed in the housing 1. The developing element 11 extends along a first direction / left-right direction and can rotate about a rotation axis L1 parallel to the first direction. In a second direction / front-back direction, the developing element 11 is located at one end of the housing 1. After the developing cartridge 100 is combined with the drum 900, the developing element 11 is opposite to the photosensitive element 910 disposed in the drum 900. The developing element 11 is used to transport the developer to the photosensitive element 910. The developing cartridge 100 also includes a driving force receiver 12 disposed at one end of the housing 1 in a first direction. The driving force receiver 12 is used to receive the driving force provided by the imaging device, thereby driving the developing element 11 to rotate. The developing cartridge 100 also includes a chip holder 3, a chip 4, a movable member 5, and a cover 21 located at one end of the housing 1 in the first direction. The chip 4 is disposed in the chip holder 3 and supported by the chip holder 3. The chip holder 3, the chip 4, and the movable member 5 can constitute a chip assembly. The chip 4 can move from a first position where it does not form an electrical connection / contact with the electrical contact pin 004 to a second position where it forms an electrical connection / contact with the electrical contact pin 004. The movable member 5 allows the chip 4 to move between the first position and the second position. In this invention, the chip holder 3, the chip 4, the movable member 5, and the cover 21 are located at the same end as the driving force receiver 12. In the first direction / left-right direction, the cover 21 and the housing 1 are interconnected. At least a portion of the driving force receiver 12 can be exposed to the outside through the cover 21. Furthermore, the upper wall 002 and the lower wall 003, facing each other, form a guide rail for guiding the developing cartridge 100. During the installation of the developing cartridge 100, the chip holder 3, together with the chip 4, is installed along the guide rail until the electrical contact portion 42 (described later) makes electrical connection / contact with the electrical contact pin 004.

[0091] Furthermore, the end where the driving force receiver 12 is located can be defined as the driving end, and the other end opposite to the driving end in the first direction can be defined as the non-driving end.

[0092] The developing cartridge 100 also includes a handle 13, which is combined with the housing 1 to facilitate the user's grip for installation and removal of the developing cartridge 100. In the second direction, the handle 13 and the developing component 11 are located at opposite ends of the housing 1.

[0093] Furthermore, along the first direction / left-right direction, the chip assembly is located on the left, and the opposite side is the right. Along the second direction / front-back direction, the developing element 11 is located in front, and the handle 13 is located in the rear. Figure 34B In the indicated state, the direction of gravity is downward, and vice versa. The installation direction of the developer cartridge 100 is forward, and the removal direction is backward.

[0094] Example 1

[0095] Figure 34CThis is an exploded view of some components of the developing cartridge according to Embodiment 1 of this utility model; Figure 34A-34C and Figure 35 This is a schematic diagram of the movable component involved in Embodiment 1 of this utility model; Figure 36A and Figure 36B This is a schematic diagram of the chip socket involved in Embodiment 1 of this utility model; Figure 37 This is a schematic diagram of the cover element involved in Embodiment 1 of this utility model; Figure 38 and Figure 39A This is a schematic diagram of the developing cartridge after the hidden parts of the developing cartridge are installed in place, according to Embodiment 1 of this utility model.

[0096] like Figure 39B , Figure 35 and Figure 36A As shown, in this embodiment, the chip assembly and the cover 21 are integrally or separately formed. Preferably, the chip assembly and the cover 21 are separately formed. The movable member 5 includes a first surface 51, an action part 52, and a third surface 53. The first surface 51 is parallel to the second direction. Further, the action part 52 is a plane (second surface) disposed on the movable member 5. The action part 52 is inclined relative to the first surface 51. The third surface 53 is inclined relative to the first direction and the second direction. The first surface 51 is used to support the chip holder 3. The action part 52 is used to guide the chip holder 3 to move upward in the third direction. The third surface 53 is used to contact the inclined surface 0011 disposed in the side wall 001. 011 is used to allow the movable member 5 to move in the second direction in the opposite direction to the installation direction; the movable member 5 also includes a baffle 54, which can restrict the movement of the movable member 5 in the second direction to prevent the movable member 5 from falling in the installation direction. The movable member 5 also includes an elastic member 59 for automatically resetting the movable member 5. The elastic member 59 can elastically deform in the second direction, for example, by stretching / extension. Optionally, the elastic member 59 can also deform in other directions. For example, a reset force can be applied to the movable member 5 by setting a conversion member. One end of the elastic member 59 abuts against the baffle 54, and the other end of the elastic member 59 abuts against the cover 21 described later. Furthermore, the baffle 54 is also provided with a protrusion 55, and the elastic member 59 can be fitted onto the protrusion 55 to prevent the elastic member 59 from shifting.

[0097] like Figure 36B and Figure 37As shown, chip 4 includes a chip substrate 41 and an electrical contact portion 42 disposed in the chip substrate 41. The electrical contact portion 42 is used for electrical connection / contact with the electrical contact 004. Chip holder 3 includes a chip mounting portion 31, a blocking portion 32, and a connecting portion 33. The connecting portion 33 is located between the chip mounting portion 31 and the movable member, and is used to make the chip mounting portion 31 move in response to the movement of the movable member 5. The chip mounting portion 31 is used to support the electrical contact portion 42 at least. The blocking portion 32 is used to engage with the positioning protrusion 0022 provided in the imaging device to position the chip 4 / chip holder 3 in a first direction, thereby making the electrical connection / contact between the chip 4 and the electrical contact 004 more stable and reliable. There is a gap portion 34 between the chip mounting portion 31 and the blocking portion 32. The gap portion 34 is used to engage with the positioning protrusion 0022. The connecting portion 33 includes an activated portion 331 and a second portion 332. The activated portion 331 is configured as the first portion 331, as shown in the figure. Figure 38 As shown, in the first direction, the affected part 331 is further away from the housing 1 than the second part 332. In the third direction, the affected part 331 is closer to the chip mounting part 31 than the second part 332. The affected part 331 includes a mating surface 3311, which is used to engage with the actuating part 52 of the movable member 5 so that the chip 4 / chip holder 3 moves upward in the third direction, thereby making the chip 4 electrically connected / contact with the electrical contact pin 004. The second part 332 is used to engage with the cover 21. The second part 332 includes a cantilever 3321 and a latching part 33211 provided at the end of the cantilever 3321. The latching part 33211 is used to engage with the cover 21 to restrict the movement of the chip holder 3 in the third direction, thereby preventing the chip holder 3 from falling off.

[0098] like Figure 37As shown, the cover 21 includes a cover body 210, a first plate 211, a second plate 212, a third plate 213, and a fourth plate 214 connected to the cover body 210. The first plate 211 and the second plate 212 are perpendicular to a third direction, while the third plate 213 and the fourth plate 214 are perpendicular to a second direction. A connecting plate 215 is provided between the first plate 211 and the second plate 212. Furthermore, the movable member 5 is supported by the first plate 211 and clamped by the first plate 211 and the second plate 212. Simultaneously, the movable member 5 is also secured by a first latch 2111 provided on the first plate 211 and a second latch 2121 provided on the second plate 212. This prevents the movable part 5 from falling off in the first direction. The fourth plate 214 is combined with the first plate 211. In the second direction, the chip holder 3 is clamped by the third plate 213 and the fourth plate 214. The chip holder 3 moves in the third direction along the guide channel formed between the third plate 213 and the fourth plate 214. The fourth plate 214 is also provided with a hole 2141, which can be used to accommodate the snap-fit ​​part 33211 of the chip holder 3, thereby preventing the chip holder 3 from falling off from the third direction upward. The third plate 213 is also used to combine with the baffle 54 in the second direction to prevent the movable part 5 from falling off from the second direction. The connecting plate 215 is used to abut against the other end of the elastic member 59.

[0099] like Figure 38 and Figure 37 As shown, when the developing cartridge 100 is not installed in the imaging device, the elastic member 59 is in its initial state. During the installation of the developing cartridge 100, the third surface 53 of the movable member 5 abuts against the inclined surface 0011 of the side wall 001, and the movable member 5 receives a force that moves in the opposite direction to the installation direction, thereby causing the elastic member 59 to undergo elastic deformation. At the same time, the chip holder 3 is driven upward by the movable member 5. After the developing cartridge 100 is installed in place, the chip 4 moves to the second position where it is electrically connected / in contact with the electrical contact 004. When the developing cartridge 100 is disassembled, the third surface 53 of the movable member 5 is not abutted by the inclined surface 0011. Under the elastic force of the elastic member 59, the movable member 5 is pushed to move in the installation direction, and the chip holder 3 moves downward under its own gravity, thereby driving the chip 4 to the first position where it is not electrically connected / in contact with the electrical contact 004.

[0100] Furthermore, the above operations can also be performed in other parts of the imaging device, not limited to the inclined plane 0011.

[0101] In other embodiments, the chip holder 3 may be integrally formed with or separate from the housing 1.

Figure 39B This is a schematic diagram of the developing cartridge after the hidden parts of the developing cartridge are installed in place, according to Embodiment 2 of this utility model.

[0104] This embodiment differs from the way the movable part 5 drives the chip holder 3 in Embodiment 1, as detailed below.

[0105] like Figure 39A and Figure 39B As shown, in this embodiment, the chip assembly and the cover 21 are integrally or separately formed. Preferably, the chip assembly and the cover 21 are separately formed. The chip assembly also includes an intermediate member 6 that is simultaneously engaged with the chip holder 3 and the movable member 5. In this embodiment, the intermediate member 6 is a gear, which is disposed in the cover 21 and can rotate about a rotation axis parallel to the first direction. The movable member 5 includes a first surface 51, an action part 52 disposed on the first surface 51, and a third surface 53. Further, the action part 52 is a first protrusion, which is used to engage with the second protrusion 61 of the gear 6. This allows the movable part 5 to rotate in the second direction when it is abutted by the imaging device, thereby driving the gear 6 to rotate. Furthermore, in the front-rear direction, the actuating part 52 is located at the front end of the first surface 51. The movable part 5 also includes a baffle 54, which restricts the movement of the movable part 5 in the second direction to prevent it from falling off along the installation direction. The movable part 5 also includes an elastic element 59 for automatically resetting the movable part 5. The elastic element 59 can extend / stretch in the second direction, with one end abutting against the baffle 54 and the other end abutting against the cover 21. In other embodiments, the intermediate part 6 can also be a bevel gear, or its rotation axis can be parallel to the second / third direction; the intermediate part 6 can also be positioned in other locations according to design requirements, and its rotation axis is not necessarily parallel to the second / third direction.

[0106] like Figure 40A and Figure 40BAs shown, the chip holder 3 includes a chip mounting portion 31, a blocking portion 32, and a connecting portion 33. The chip mounting portion 31 is used to connect with the chip 4, so that the chip 4 is mounted. The blocking portion 32 is used to connect with the positioning protrusion 0022 provided in the imaging device to position the chip 4 / chip holder 3 in a first direction, thereby making the electrical connection / contact between the chip 4 and the electrical contact pin 004 more stable and reliable. There is a gap portion 34 between the chip mounting portion 31 and the blocking portion 32, which is used to engage with the positioning protrusion 0022. The connecting portion 33 includes an activated portion 331 spaced along a third direction. Further, the activated portion 331 is configured as a third protrusion. The activated portion 331 is used to engage with the second protrusion 61 of the gear 6, so that the chip holder 3 can be driven by the gear 6 to move in a third direction, thereby making the chip 4 electrically connected / contact with the electrical contact pin 004. A cantilever 332 and a latching portion 3321 are provided on the side opposite to the activated portion 331 in the second direction. The latching portion 3321 is used to engage with the cover to restrict the movement of the chip holder 3 in the third direction, thereby preventing the chip holder 3 from falling off. The connecting portion 33 also includes a first clearance portion 333 located between the activated portion 331 and the cantilever 332. The first clearance portion 333 is used to engage with a part of the cover 21.

[0107] like Figure 41 As shown, the cover 21 includes a cover body 210, a first plate 211, a second plate 212, a third plate 213, and a fourth plate 214 connected to the cover body 210. The first plate 211 and the second plate 212 are perpendicular to a third direction, while the third plate 213 and the fourth plate 214 are perpendicular to a second direction. A connecting plate 215 is provided between the first plate 211 and the second plate 212. Furthermore, the movable member 5 is supported by the first plate 211 and clamped by the first plate 211 and the second plate 212. Simultaneously, the movable member 5 is also secured by a first latch 2111 on the first plate 211 and a second latch 2121 on the second plate 212, thereby preventing the movable member 5 from falling off in the first direction. The third plate 213... The fourth plate 214 is respectively combined with the first plate 211. A portion of the chip holder 3 is clamped by the third plate 213 and the fourth plate 214. Specifically, the first clearance portion 333 is used to accommodate the fourth plate 214 so that the acted portion 331 can engage with the gear 6. The chip holder 3 moves in the third direction along the guide channel formed between the third plate 213 and the fourth plate 214. The third plate 213 is also provided with a hole 2131, which can be used to accommodate the snap-fit ​​portion 3321 of the chip holder 3, thereby preventing the chip holder 3 from falling off upwards in the third direction. The third plate 213 is also used to combine with the baffle 54 in the second direction to prevent the movable part 5 from falling off in the second direction. The connecting plate 215 is used to abut against the other end of the elastic member 59. The cover 21 also includes a column 216 connected to the cover body 210. The column 216 extends in the first direction and is used to install the gear 6.

[0108] Furthermore, the aforementioned actuating part 52, second protrusion 61, and acted part 331 can be teeth or rough surfaces.

[0109] like Figure 42 and Figure 40A As shown, when the developing cartridge 100 is installed in place, the third surface 53 of the movable member 5 abuts against the inclined surface 0011 of the side wall 001, and the movable member 5 receives a force to move in the opposite direction to the installation direction, thereby compressing the elastic member 59. At the same time, the actuating part 52 of the movable member 5 drives the second protrusion 61 of the gear 6, causing the gear 6 to rotate in the direction r. The second protrusion 61 of the gear 6 then engages with the acted part 331 of the chip holder 3, thereby causing the chip holder 3 to move upward in the third direction, thereby electrically connecting / contacting the electrical contact pin 004.

[0110] Furthermore, the above operations can also be performed in other parts of the imaging device, not limited to the inclined plane 0011.

[0111] In other embodiments, the chip holder 3 may be integrally formed with or separate from the housing 1.

Figure 44 This is a schematic diagram of the developing cartridge after the hidden parts of the developing cartridge are installed in place, according to Embodiment 3 of this utility model.

[0114] The movement mode of the chip holder 3 in this embodiment differs from that in the above embodiments, as detailed below.

[0115] like Figure 45A , Figure 45BAs shown, in this embodiment, the chip assembly and the cover 21 are integrally / separately formed. Preferably, the chip assembly and the cover 21 are separately formed. The chip holder 3 is configured to rotate about a rotation axis parallel to the first direction. The chip assembly also includes an intermediate member 6 connected to the chip holder 3. In this embodiment, the intermediate member 6 is a gear, and the gear 6 is integrally / separately formed with the chip holder 3. Specifically, the movable member 5 includes a first surface 51, an action portion 52 disposed above the first surface 51, and a third surface 53. Further, the action portion 52 is configured as a first protrusion, and a second clearance portion 54 is provided between the first surface 51 and the action portion 52. The second clearance portion 54 is used to engage with a part of the cover 21. The action portion 52 is used to engage with the action portion 61 disposed on the gear 6. The action portion 61 is configured as a second protrusion. Further, along the vertical direction, the action portion 52 is located above the first surface 51. The movable member 5 also includes a receiving portion 55 with an opening facing the housing 1. The receiving portion 55 is used to engage with a part of the cover 21. The movable part 5 also includes an elastic part 59 that can extend and retract in the second direction. The elastic part 59 is accommodated by the receiving part 55. One end of the elastic part 59 abuts against the contact surface 551 of the receiving part 55, and the other end abuts against the cover 21.

[0116] As shown in the figure, the cover 21 includes a cover body 210, a first plate 211, a second plate 212, and a third plate 213 connected to the cover body 210. The first plate 211 can be used to support the movable member 5. The second plate 212 can be accommodated by the second clearance part 54, and the movable member 5 is fastened by the snap-fit ​​part 2123 provided on the second plate 212 to prevent the movable member 5 from falling off in the first direction. The third plate 213 is accommodated by the receiving part 55. At this time, the receiving part 55 can be regarded as a guide groove, and the third plate 213 can be regarded as a guide part. The other end of the elastic member 59 abuts against the third plate 213.

[0117] As shown in the figure, the chip holder 3 has a cylindrical structure. When viewed along the first direction, the chip holder 3 is an eccentric circle. Furthermore, the chip 4 / electrical contact part 42 is set in an arc shape. Along the radial direction of the chip holder 3, the side opposite to the chip 4 is set as a plane 301. Furthermore, the chip 4 and the plane 301 are located at opposite ends of the chip holder 3 in the radial direction. During the installation of the developing cartridge 100, the plane 32 can prevent the chip holder 3 from interfering with the imaging device, thereby ensuring smooth installation. The gear 6 can be directly connected to the chip holder 3, or it can be connected through the transmission part 63. The other side of the gear 6 is provided with a mating part 62, which is used to mate with the mated part 214 provided on the cover 21 to install the gear 6 and the chip holder 3.

[0118] After the developing cartridge 100 is installed in place, the third surface 53 of the movable part 5 abuts against the inclined surface 0011 of the side wall 001, as shown. Figure 46A and Figure 46BAs shown, the movable member 5 receives a force that moves in the opposite direction to the installation direction, thereby causing the elastic member 59 to deform elastically. At the same time, the actuating part 52 of the movable member 5 drives the acted part 61 of the gear 6, causing the gear 6 to rotate in the direction r, thereby causing the chip holder 3 to rotate in the direction r, and causing the chip 4 to rotate from facing downward to facing upward, thereby electrically connecting / making contact with the electrical contact pin 004.

[0119] In other embodiments, the chip holder 3 may be integrally formed with or separate from the housing 1.

[0120] [Transformation Method]

[0121] Figure 47A This is a schematic diagram of the chip holder and gear involved in a variation of Embodiment 3 of this utility model.

[0122] like Figure 47B As shown, based on Embodiment 3, in this modified embodiment, the chip 4 / electrical contact 42 is configured as a planar shape.

[0123] Furthermore, the above operations can also be performed in other parts of the imaging device, not limited to the inclined plane 0011.

[0124]

Example 4

[0125] Figure 43A This is a perspective view of the hidden components of the developing cartridge according to Embodiment 4 of this utility model; Figure 43B This is an exploded view of some components of the developing cartridge involved in Embodiment 4 of this utility model; Figure 44 This is a schematic diagram of the chip holder and movable component involved in Embodiment 4 of this utility model; Figure 45A This is a schematic diagram of the developing cartridge before it is installed in place, after the hidden parts of the developing cartridge are removed, according to Embodiment 4 of this utility model. Figure 45B This is a schematic diagram of the developing cartridge after the hidden parts of the developing cartridge are installed in place, according to Embodiment 4 of this utility model.

[0126] The difference between this embodiment and the above embodiment lies in the direction of movement of the movable member 5, as detailed below.

[0127] like Figure 46A , Figure 46B , Figure 47A , Figure 47B and ​As shown, similar to the above embodiment, the chip holder 3 includes a chip mounting portion 31, a blocking portion 32, and a spacer portion 34 between the chip mounting portion 31 and the blocking portion 32. The movable member 5 / chip assembly is integrally or separately formed with the cover 21. Preferably, the movable member 5 / chip assembly is separately formed with the cover 21. The difference is that in this embodiment, the movable member 5 can move upwards in the third direction. Furthermore, the movable member 5 is configured as an elastic component, for example, it can be a sponge, rubber, etc. The chip holder 3 is connected to the upper surface 51 of the movable member 5. The movable member 5 is installed in the first receiving cavity 211 provided in the cover 21, and the chip 4 is exposed from the opening 2111 facing upwards from the first receiving cavity 211. Furthermore, the movable member 5 is also provided with an error-proofing portion 52 to prevent the chip 4 from being installed incorrectly.

[0128] Before the developer cartridge 100 is installed, the movable part 5 is in its initial state. At this time, the movable part 5 is subject to its own weight and the weight of the chip holder 3. During the installation of the developer cartridge 100, the movable part 5 is compressed due to the restriction of the lowest point 0021 of the upper wall 002. When the developer cartridge 100 is installed in place, the movable part 5 releases its elasticity, thereby making the electrical contact part 42 of the chip 4 electrically connected / in contact with the electrical contact pin 004.

[0129] In other embodiments, the chip holder 3 can be omitted, and the chip 4 can be directly fixed on the movable part 5. This can reduce the number of parts and reduce the difficulty and complexity of assembly.

[0130] In other embodiments, the movable part 5 / chip assembly may be integrally formed with or separate from the housing 1.

[0133] The difference between this embodiment and the above embodiments lies in the structure of the movable part 5, as detailed below.

[0134] like ​ , ​ , ​ and ​As shown, similar to the above embodiment, the chip holder 3 includes a chip mounting portion 31, a blocking portion 32, and a spacer portion 34 between the chip mounting portion 31 and the blocking portion 32. The difference is that in this embodiment, the movable member 5 is disposed on the housing 1. The movable member 5 / chip assembly is integrally formed with or separate from the housing 1. Preferably, the movable member 5 / chip assembly is separately formed from the housing 1. Specifically, the movable member 5 has a cantilever / elastic member 51 extending in a first direction. Furthermore, the movable member 5 passes through a through hole 211 provided in the cover member 21 in the first direction, thereby exposing the chip 4.

[0135] Before the developing cartridge 100 is installed, the movable part 5 is in its initial state. During the installation of the developing cartridge 100, due to the restriction of the lowest point 0021 of the upper wall 002, the movable part 5 is pressed downward, and the elastic part 51 is deformed, so that the movable part 5 / chip 4 is tilted (not parallel to the first direction). When the developing cartridge 100 is installed in place, the elastic part 51 releases its elastic force, the movable part 5 returns to its initial state, and the movable part 5 / chip 4 is no longer tilted, so that the electrical contact part 42 of the chip 4 is electrically connected / in contact with the electrical contact pin 004.

[0136] Furthermore, the elastic element 51 can be made of materials such as silicone or natural rubber.

[0137] In other embodiments, the chip holder 3 can be omitted, and the chip 4 can be directly fixed on the movable part 5. This can reduce the number of parts and reduce the difficulty and complexity of assembly.

[0138] In other embodiments, the movable part 5 / chip assembly may be integrally formed with or separate from the cover 21.

[0141] The difference between this embodiment and the above embodiment lies in the way that the movable part 5 drives the chip holder 3 to move, as detailed below.

[0142] like ​ , ​ , ​ As shown, in this embodiment, the movable member 5 and the chip holder 3 are disposed in the cover member 21, that is, the chip assembly and the cover member 21 are integrally formed / separately formed. Preferably, the chip assembly and the cover member 21 are separately formed. The chip holder 3 includes a chip mounting part 31 and a blocking part 32. The chip mounting part 31 is used to engage with the chip 4 so that the chip 4 is mounted. The blocking part 32 is used to engage with the positioning protrusion 0022 provided in the imaging device to position the chip 4 / chip holder 3 in a first direction, thereby making the electrical connection / contact between the chip 4 and the electrical contact 004 more stable and reliable. There is a gap 34 between the chip mounting part 31 and the blocking part 32, which is used to engage with the positioning protrusion 0022. The chip mounting part 31 also includes two stops 35 disposed opposite to each other in a second direction. The two stops 35 are respectively used to engage with the cover member 21 and can also be used to guide the chip holder 3 / chip 4 to move in a direction intersecting with the third direction.

[0143] Continuing as shown in the figure, the chip assembly also includes an intermediate component 6 that engages with both the chip holder 3 and the movable component 5. In this embodiment, the intermediate component 6 is configured as a lever extending along a first direction. The lever 6 includes a main body 61 and recesses (one embodiment of a mating part) 62 and second protrusions (one embodiment of a transmission part) 63 disposed at both ends of the main body 61. The recesses 62 are used to engage with the movable component 5, and the main body 61 and the second protrusions 63 are used to engage with the chip holder 3. Preferably, the lever 6 can rotate about a rotation axis parallel to the second direction. Specifically, the lever 6 also includes a mounting part 64 extending in the second direction. The main body 61 is connected to the mounting part 64, and the mounting part 64 is used to engage with the cover 21 to allow the lever 6 to rotate.

[0144] As shown in the figure, the movable member 5 is configured to extend along a third direction. The movable member 5 includes a third clearance portion 51, a first protrusion 52, a contact portion 53, and a blocking member 55 accommodated by the third clearance portion 51. The first protrusion 52 is used to engage with the recess 62 of the lever 6, and the contact portion 53 is used to engage with the top plate 006. During the installation of the developing cartridge 100, the contact portion 53 is abutted by the top plate 006 and moves downward along the third direction as the developing cartridge 100 continues to move toward the installation direction, causing the lever 6 to rotate. This causes the second protrusion 63 of the lever 6 to tilt upward, thereby causing the chip holder 3 / chip 4 to move upward and make electrical connection / contact with the electrical contact pin 004. The third clearance portion 51 also accommodates an elastic member 59 that can extend and retract in the third direction. One end of the elastic member 59 abuts against the upper end of the third clearance portion 51, and the other end abuts against the blocking member 55. The blocking member 55 is used to abut against the cover 21. When the movable member 5 moves downward along the third direction, the elastic member 59 undergoes elastic deformation. Preferably, the blocking member 55 is provided with a protrusion 551, which is used to position the elastic member 59 to prevent the elastic member 59 from shifting.

[0145] like ​ and ​ As shown, the cover 21 includes a cover body 210, a first receiving cavity 211 and a second receiving cavity 212 connected to the cover body 210. The first receiving cavity 211 is used to receive the chip holder 3 / chip 4, and the second receiving cavity 212 is used to receive a part of the movable part 5. Further, the first receiving cavity 211 has an upward-facing first opening 2111 and a guide groove 2112. The first opening 2111 is used to expose the chip 4 upward, and the guide groove 2112 is used to engage with the stop 35 of the chip holder 3 to guide the chip holder 3 / chip 4 to move upward. The number of guide grooves 2112 corresponds to the number of stop 35, that is, two are set, so that the movement of the chip holder 3 / chip 4 can be more stable. Further, the second receiving cavity 212 is provided through in a third direction. The second receiving cavity 212 has two holes 2121 disposed opposite to each other in the first direction to facilitate the movement of the movable member 5 in the third direction. The holes 2121 are used to receive the protrusions 54 provided on the movable member 5 to limit the range of movement of the movable member 5 in the third direction. The protrusions 54 can also prevent the movable member 5 from falling off in the third direction. Furthermore, the cover 21 also includes a mounting part 213 disposed below the second receiving cavity 212. The mounting part 213 is used to engage with the mounting part 64 to install the lever 6. The mounting part 64 and the mounting part 213 are engaged in a shaft-hole engagement. Specifically, the mounting part 64 can be configured as a shaft-shaped structure and the mounting part 213 as a hole-shaped structure, or the mounting part 64 can be configured as a hole-shaped structure and the mounting part 213 as a shaft-shaped structure.

[0146] As shown in Figures 24A(1) and 24A(2), when the developing cartridge 100 is installed, the second protrusion 63 of the lever 6 does not tilt upward, and the chip 4 is located in the first receiving cavity 211. As the developing cartridge 100 continues to be installed, the movable part 5 is abutted by the top plate 006 and moves downward, causing the second protrusion 63 of the lever 6 to tilt upward, thereby driving the chip holder 3 / chip 4 to move upward, and the elastic part 59 is compressed. As shown in Figures 24B(1) and 24B(2), when the developing cartridge 100 is installed in place, the chip 4 protrudes from the first receiving cavity 211 and is electrically connected / contacted with the electrical contact pin 004.

[0147] Furthermore, the upward movement of chip 4 can be either diagonally upward or vertically upward, as long as it achieves electrical connection / contact between chip 4 and electrical contact pin 004. In other embodiments, the chip assembly can be configured to be integrally formed with or separate from the housing 1.

[0150] like ​ , ​ and ​As shown, the chip holder 3 includes a chip mounting portion 31, a blocking portion 32, and a handle portion 341. The chip mounting portion 31 is used to engage with the chip 4 to mount the chip 4. The blocking portion 32 is used to engage with the positioning protrusion 0022 provided in the imaging device to position the chip 4 / chip holder 3 in a first direction, thereby making the electrical connection / contact between the chip 4 and the electrical contact pin 004 more stable and reliable. There is a gap portion 34 between the chip mounting portion 31 and the blocking portion 32, which is used to engage with the positioning protrusion 0022. The handle portion 341 extends in a second direction and includes an abutment surface 338a, a fourth clearance portion 338b, and a contact portion 338c. The cover 21 includes a cover body 210 and a handle portion connected to the cover body 210. The guide plate 211 includes a first guide surface 2111 and a second guide surface 2112. The first guide surface 2111 is parallel to the second direction, and the second guide surface 2112 intersects the second direction. The second guide surface 2112 is used to engage with the abutment surface 338a to guide the chip assembly to move upward. The fourth clearance part 338b is used to hook a finger to facilitate the removal of the chip assembly. The contact part 338c is used to abut against the rear cover 005 of the imaging device. As the rear cover 005 is gradually closed, the chip assembly is pushed by the rear cover 005 along the installation direction, thereby causing the abutment surface 338a to move along the second guide surface 2112 and causing the chip 4 to move upward, thereby electrically connecting / making contact with the electrical contact pin 004.

[0151] [Transformation Method 1]

[0152] ​ This is a perspective view of the hidden components of the developing cartridge, which is a variation of Embodiment 7 of this utility model.

[0153] like ​ As shown, based on Embodiment 7, the chip holder 3 in this modified embodiment further includes a locking part 334, which is used to engage with the locking part 212 provided in the cover body 210, so that after the developing cartridge 100 is installed in place, the chip assembly is limited to prevent the chip 4 / chip assembly from moving, thereby ensuring the stability of the communication connection between the developing cartridge 100 and the imaging device.

[0154] [Transformation Method Two]

[0155] ​ This is a schematic diagram of the chip assembly involved in a variation of Embodiment 7 of this utility model; ​ This is a schematic diagram of the installation process before the chip assembly is installed in place, according to a variation of Embodiment 7 of this utility model. ​ This is a schematic diagram of the chip assembly after it has been installed in place, according to a variation of Embodiment 7 of this utility model.

[0156] like ​ , ​ ,​ As shown, based on Embodiment 7, in this modified embodiment, the handle portion 341 is further provided with a downwardly extending abutment portion 334. The abutment portion 334 is elastic, and the end portion 335 of the abutment portion 334 is used to abut against the lower wall 003. The handle portion 341 also includes an extension portion 336 extending outward from the end portion 335. When viewed along the first direction, the abutment portion 334 and the extension portion 336 intersect each other.

[0157] During the closing of the back cover 005, the chip holder 3 is pushed by the back cover 005 and moves along the installation direction. During the movement, the chip holder 3 is abutted by the upper wall 002 and the lower wall 003. Specifically, the chip mounting part 31 is abutted by the upper wall 002, and the end 335 of the abutting part 334 is abutted by the lower wall 003, causing the abutting part 334 to undergo elastic deformation (compression). When the chip mounting part 31 passes the lowest point 0021 of the upper wall 002, the abutting part 334 is further compressed. As the chip assembly is installed in place, the end 335 of the abutting part 334 enters the lowest point 0032 of the lower wall 003, the abutting part 334 is stuck, and the chip assembly is positioned. As the back cover 005 gradually closes, the chip assembly is pushed by the back cover 005 along the installation direction, thereby causing the abutting surface 338a to move along the second guide surface 2112 and causing the chip 4 to move upward, thereby making electrical connection / contact with the electrical contact pin 004.

[0158] In this embodiment and its variations, the handle portion 341 can be regarded as at least a part of the movable member 5. In this way, at least a part of the movable member 5 is integrally formed with the chip holder 3, which can reduce the number of parts and reduce costs.

[0159] Furthermore, the chip holder 3 can be removed, and the chip 4 can be directly connected to the movable part 5 / handle part 341.

[0160] In this embodiment and its variations, the chip holder 3 is integrally or separately formed with the housing 1 or the cover 21. When the chip holder 3 is separately formed with the housing 1 or the cover 21, the chip assembly can be transported and sold as an independent component.

[0161] Furthermore, in the above embodiments one to seven, in the first position, chip 4 is in a retracted state, and in the second position, chip 4 is in an extended state.

[0162] By making the chip assembly movable in the above embodiments one to seven, the chip assembly will not interfere with the components in the imaging device before the developing cartridge is installed in place, thereby making the developing cartridge installation smooth and protecting the chip from damage.

[0165] During the installation of the developing cartridge 100 into the imaging device along the installation direction, the chip holder 3 disposed in the developing cartridge 100 will move along the upper wall 002 (e.g., the developing cartridge 100) along the developing cartridge 100. ​ and ​ (As shown) Move, and then install in place, so that chip 4 and electrical contact 004 (as shown) are connected. ​ and ​ (As shown) Electrical connection / electrical contact.

[0166] The difference between this embodiment and Embodiment 5 lies in the structure of the chip assembly, as detailed below.

[0167] like ​ and ​ As shown, in this embodiment, the movable component 5 is omitted, and the chip holder 3 is directly mounted on the cover 21 or the housing 1. Alternatively, the chip holder 3 and the movable component 5 can be considered as being integrally formed. Preferably, the chip holder 3 is mounted on the cover 21; the chip 4 is mounted on the chip holder 3 and supported by the chip holder 3. In some embodiments, the chip holder 3 can also be mounted on a component connected to the housing 1, such as a bearing plate or a bracket.

[0168] Furthermore, the chip holder 3 includes a chip mounting portion 31 and a connecting member. The chip mounting portion 31 is used to mount / support the chip 4. Further still, a guide surface 311 is provided on the side of the chip mounting portion 31 near the housing 1. This guide surface 311 has a guiding function, used to guide the positioning protrusion 0022, so that the engagement / contact between the chip mounting portion 31 and the positioning protrusion 0022 is smoother, thereby preventing the chip mounting portion 31 from being stuck and unable to be installed in place. In this embodiment, the chip holder 3 also includes a spacer portion 34. After the developing cartridge 100 is installed in place, the spacer portion 34 is used to accommodate / avoid the positioning protrusion 0022 in the imaging device, so that the positioning protrusion 0022 restricts the movement of the chip holder 3 in the first direction, so that the chip 4 maintains a stable electrical connection / contact with the electrical contact pin 004, thereby maintaining a stable communication connection between the developing cartridge 100 and the imaging device. The connecting member is used to combine with the cover 21 to allow the chip... The chip holder 3 is installed. In this embodiment, preferably, the connecting member includes a first connecting part 361 and a second connecting part 362. The first connecting part 361 is used to engage with a first connected part 218a provided on the cover 21, and the second connecting part 362 is used to engage with a second connected part 218b provided on the cover 21. Further, the first connecting part 361 and the first connected part 218a are in a shaft-hole fit, preferably an interference fit, so that the chip holder 3 is disposed on the cover 21. Preferably, in this embodiment, the first connected part 218a and the second connecting part 362 are configured as a shaft structure, and the second connected part 218b and the first connecting part 361 are configured as a hole structure. Further, the engagement of the first connecting part 361 with the first connected part 218a and the engagement of the second connecting part 362 with the second connected part 218b can prevent the chip holder 3 from swinging around the axis (first connecting part 361) parallel to the first direction. In other embodiments, the connecting member can also be configured as a square structure, and the connection member combined with the cover 21 can also prevent the chip holder 3 from swinging.

[0169] In some imaging devices, the positioning protrusion 0022 for guidance is not provided, and in this case, the chip holder 3 may not have the spacer 34.

[0170] In some embodiments, in the second direction, at least a portion of the first connecting portion 361 and / or the second connecting portion 362 is closer to the developing element 11 than the chip 4. In some embodiments, the free end of the first connected portion 218a is also provided with a latch, which is used to fasten the end of the first connecting portion 361 in the first direction; or, the free end of the second connecting portion 362 is provided with a latch, which is used to fasten the end of the second connected portion 218b in the first direction; or, both the free ends of the first connected portion 218a and the second connecting portion 362 are provided with latches. In this way, the latches can prevent the chip holder 3 from falling off the cover 21.

[0171] Furthermore, at least a portion of the chip holder 3 is made of a soft, elastic material, such as silicone or rubber. During the installation of the developing cartridge 100, the chip holder 3 can deform when it comes into contact with the upper wall 002 in the imaging device, thus avoiding interference with the upper wall 002 and allowing the developing cartridge 100 to be installed smoothly. Preferably, the entire chip holder 3 is made of a soft, elastic material, so that even if the chip holder 3 collides with the imaging device during the installation of the developing cartridge 100, it is not easily damaged. In addition, the chip holder 3 is not easily damaged when the developing cartridge 100 is dropped.

[0172] Furthermore, during the installation of the developing cartridge 100, the chip holder 3 can deform downward along a third direction, thereby causing the chip mounting part 31 to move downward. When the developing cartridge 100 is installed in place, the chip holder 3 recovers under its own elastic force and drives the chip mounting part 31 to move upward, thereby making the chip 4 electrically connected / contact with the electrical contact pin 004.

[0173] In some embodiments, the chip assembly further includes a conductive connector for electrically connecting / contacting the electrical contact pin 004 and the chip 4, with the chip holder 3 configured to support at least a portion of the conductive connector.

[0174] Example 9

[0175] ​ and ​ This is a schematic diagram of the chip assembly involved in Embodiment Nine of this utility model.

[0176] like ​ and ​As shown, the chip holder 3 can be connected to the housing 1 or to a component (e.g., a bearing plate, a bracket, etc.) independently disposed on the housing 1. In this embodiment, the chip holder 3 is preferably disposed on the cover 21. The chip holder 3 includes a chip mounting part 31 and a connecting component. Further, the chip mounting part 31 is used to mount / support the chip 4. More further, a guide surface 311 is provided on the side of the chip mounting part 31 near the housing 1. The guide surface 311 has a guiding function to guide the positioning protrusion 0022, so that the cooperation / contact between the chip mounting part 31 and the positioning protrusion 0022 is smoother, thereby preventing the chip mounting part 31 from being stuck and unable to be installed in place. In this embodiment, the chip holder 3 also includes a spacer 34. After the developing cartridge 100 is installed in place... The spacer 34 is used to accommodate / avoid the positioning protrusion 0022 in the imaging device, so that the positioning protrusion 0022 restricts the movement of the chip holder 3 in the first direction, so that the chip 4 and the electrical contact pin 004 maintain a stable electrical connection / contact, thereby making the communication connection between the developing cartridge 100 and the imaging device stable; the connecting member is used to combine with the cover 21 to install the chip holder 3. In this embodiment, preferably, the connecting member includes a first connecting part 361 and a second connecting part 362. In this embodiment, during the installation of the developing cartridge 100, when the chip holder 3 abuts against the upper wall 002 in the imaging device, the chip holder 3 deforms in the second direction; preferably, a cutout 371 is provided between the chip mounting part 31 and the first connecting part 361.

[0177] Furthermore, at least a portion of the chip holder 3 is made of a soft, elastic material, such as silicone or rubber. During the installation of the developing cartridge 100, the chip holder 3 can deform when it comes into contact with the upper wall 002 in the imaging device, thus preventing the chip mounting portion 31 from having a hard collision with the upper wall 002. Moreover, compared to Embodiment 8, the hollow portion 371 allows for a greater degree of deformation of the chip holder 3, thereby making the developing cartridge 100 easier to install and better preventing damage to the chip holder 3. Preferably, the chip holder 3 is made entirely of a soft, elastic material, so that it is not easily damaged even if it collides with the imaging device during the installation of the developing cartridge 100. In addition, the chip holder 3 is not easily damaged when the developing cartridge 100 is dropped.

[0178] Furthermore, during the installation of the developing cartridge 100, the chip holder 3 can deform backward in the second direction, causing the chip mounting part 31 to move backward to avoid damage. When the developing cartridge 100 is installed in place, the chip holder 3 recovers under its own elastic force and drives the chip mounting part to move forward, thereby making the chip 4 electrically connected / contact with the electrical contact pin 004.

[0179] In some imaging devices, the positioning protrusion 0022 for guidance is not provided, and in this case, the chip holder 3 may not have the spacer 34.

[0180] In some embodiments, in the second direction, at least a portion of the first connecting portion 361 and / or the second connecting portion 362 is closer to the developing element 11 than the chip 4.

[0181] In some embodiments, the chip assembly further includes a conductive connector for electrically connecting / contacting the electrical contact pin 004 and the chip 4, with the chip holder 3 configured to support at least a portion of the conductive connector.

[0183] ​ This is a perspective view of the hidden components of the developing cartridge according to Embodiment 10 of this utility model; ​ This is an exploded view of some components of the developing cartridge involved in Embodiment 10 of this utility model; ​ This is a schematic diagram of the chip assembly involved in Embodiment 10 of this utility model.

[0184] The chip holder 3 can be connected to the housing 1 or to a component (e.g., a bearing plate, a bracket, etc.) independently disposed on the housing 1. In this embodiment, the chip holder 3 is preferably disposed on the cover 21. The chip holder 3 includes a chip mounting part 31 and a connecting component. Further, the chip mounting part 31 is used to mount / support the chip 4. Moreover, a guide surface 311 is provided on the side of the chip mounting part 31 near the housing 1. The guide surface 311 has a guiding function to guide the positioning protrusion 0022, so that the cooperation / contact between the chip mounting part 31 and the positioning protrusion 0022 is smoother, thereby preventing the chip mounting part 31 from being stuck and unable to be installed in place. In this embodiment, the chip holder 3 further includes a spacer 34. After the developing cartridge 100 is installed in place, the spacer 34 is used to accommodate / avoid the positioning protrusion 0022 in the imaging device, so that the positioning protrusion 0022 restricts the movement of the chip holder 3 in the first direction, so that the chip 4 and the electrical contact pin 004 maintain a stable electrical connection / contact, thereby making the communication connection between the developing cartridge 100 and the imaging device stable. The connecting member is used to combine with the cover 21 to install the chip holder 3. In this embodiment, preferably, the connecting member includes a first connecting part 361 and a second connecting part 362. Furthermore, in this embodiment, the chip assembly is also provided with an elastic member, as follows.

[0185] like ​As shown, the first connecting portion 361 is used to engage with the first connected portion 218a provided on the cover 21. Further, the first connecting portion 361 and the first connected portion 218a are in a shaft-hole fit. Further, the first connecting portion 361 allows the chip holder 3 to rotate relative to the cover 21 about an axis parallel to the first direction (coaxial with the first connecting portion 361). Preferably, in this embodiment, the first connecting portion 361 is configured as a hole structure, the first connected portion 218a is configured as a shaft structure, and the second connecting portion 362 is used to engage with the elastic member 59 described later. In this embodiment, the chip assembly... It also includes an elastic element 59. Further, one end of the elastic element 59 is used to connect to the second connecting part 362, and the other end is used to connect to the second connected part 218b provided on the cover 21. In some embodiments, the other end of the elastic element 59 can also be connected to a component or housing 1 independent of the cover 21. The elastic element 59 can be configured as a compression spring, a tension spring, or a torsion spring, etc. Preferably, the elastic element 59 is configured as a tension spring. Further, the free end of the second connected part 218b is provided with a third latching part 218b1, which is used to prevent the elastic element 59 from falling off in the first direction.

[0186] Furthermore, the first connecting portion 361 includes an outer circular portion 381 and an inner circular portion 382. The free end of the first connected portion 218a is provided with a first latching portion 218a1 for engaging with the inner circular portion 382. When the first latching portion 218a1 engages with the end of the inner circular portion 382, ​​the chip holder 3 is locked, thereby preventing the chip holder 3 from falling off the cover 21. In the first direction, the left end of the inner circular portion 382 is closer to the cover 21 than the left end of the outer circular portion 381. This arrangement allows the first latching portion 218a1 to engage with the inner circular portion 382. In the first direction, the first latching part 218a1 will not protrude from the outer circle part 381 / first connecting part 361, thereby preventing the first latching part 218a1 from protruding from the outer circle part 381 / first connecting part 361 and interfering with the components in the imaging device, thus preventing the developing cartridge 100 from being installed smoothly. Furthermore, the inner circle part 382 is provided with a notch part 3821. When the chip holder 3 rotates to the point where the notch part 3821 is opposite to the first latching part 218a1, the locking of the chip holder 3 is released, and the chip holder 3 can be removed from the cover 21.

[0187] Furthermore, in this embodiment, the chip socket 3 can be made of a soft elastic material or a hard material, and there is no limitation on this.

[0188] In some imaging devices, the positioning protrusion 0022 for guidance is not provided, and in this case, the chip holder 3 may not have the spacer 34.

[0189] In some embodiments, in the second direction, at least a portion of the first connecting portion 361 and / or the second connecting portion 362 is closer to the developing element 11 than the chip 4.

[0190] In some embodiments, the chip assembly further includes a conductive connector for electrically connecting / contacting the electrical contact pin 004 and the chip 4, with the chip holder 3 configured to support at least a portion of the conductive connector.

[0191] Through Embodiments 8 to 10, the chip assembly is configured such that at least a portion of it is movable relative to the housing of the developing cartridge. Before the developing cartridge is installed in place, the chip holder can deform or deflect after colliding with components in the imaging device, thereby avoiding damage to the chip holder and also making the installation of the developing cartridge smooth.

[0192] Example 11

[0193] It should be noted that the chip assembly in Embodiments 11 to 13 includes at least a chip 4 and a chip socket 3. Preferably, in the chip assembly in Embodiments 11 to 13, at least a portion of the movable member 5 overlaps with the chip socket 3.

[0194] In Examples 11 to 13, the driving end is defined as C1, and the non-driving end is defined as C2.

[0195] ​ This is a perspective view of the developing cartridge according to Embodiment Eleven of this utility model; ​ This is a perspective view of the hidden components of the developing cartridge according to Embodiment Eleven of this utility model; ​ This is an exploded view of some components of the developing cartridge according to Embodiment Eleven of this utility model; ​ This is an exploded view of the chip assembly involved in Embodiment Eleven of this utility model; ​ This is a perspective view of the chip socket according to Embodiment Eleven of this utility model; ​ and ​ This is a schematic diagram of the cover element involved in Embodiment Eleven of this utility model.

[0196] like ​ , ​ and ​ As shown, the chip assembly is disposed on the cover 21 / shell 1. In this embodiment, preferably, the chip assembly is disposed on the cover 21, and the chip assembly and the cover 21 are integrally formed / separately formed. Preferably, the chip assembly and the cover 21 are separately formed.

[0197] like ​ and ​As shown, the chip assembly includes at least a chip holder 3 and a chip 4 disposed on the chip holder 3. The chip holder 3 is disposed on the cover 21. The chip 4 is used for electrical connection / electrical contact with the electrical contact 004. Further, the chip 4 includes at least a chip substrate 41 and an electrical contact portion 42 disposed on the chip substrate 41. The electrical contact portion 42 is used for electrical connection / electrical contact with the electrical contact 004.

[0198] Continue as ​ and ​ As shown, the chip holder 3 includes at least a chip mounting portion 31 and a connecting portion 33. The chip mounting portion 31 is used to mount the chip 4, and the connecting portion 33 is used to connect with the cover 21 so that the chip holder 3 is mounted on the cover 21. Furthermore, the chip mounting portion 31 has a receiving space 312a, a first opening 312b, and a second opening 312c. The receiving space 312a is used to receive the chip 4. The first opening 312b exposes the electrical contact portion 42 of the chip 4 to allow for electrical connection / contact with the electrical contact pin 004. The second opening 312c facilitates the user to remove the chip 4 from the chip mounting portion 31, and the chip 4 can be mounted into the receiving space 312a through the second opening 312c. The chip mounting portion 31 also has a first locking portion 312d, a second locking portion 312e, and a clearance space. In section 312f, the first locking portion 312d and the second locking portion 312e are used to prevent the chip 4 from falling from the chip mounting portion 31 in the first direction / left-right direction. Specifically, the first locking portion 312d is used to abut against the first blocked portion 411a provided on the chip substrate 41 to prevent the chip 4 from being installed incorrectly, and the second locking portion 312e is used to abut against the second blocked portion 411b of the chip substrate 41. Furthermore, the second locking portion 312e has a blocking surface 312e1 facing the chip 4, and the blocking surface 312e1 abuts against the second blocked portion 411b.

[0199] Continue as ​ and ​ As shown, the connecting part 33 is provided with a first connecting part 361 and an abutting member 337 for abutting against the cover 21. The first connecting part 361 is used to cooperate with the cover 21 so that the chip holder 3 can be installed on the cover 21. Preferably, the first connecting part 361 and the cover 21 are configured to cooperate with a shaft hole. For example, the first connecting part 361 can be configured as a slot / hole structure or a protrusion / shaft structure. In this embodiment, the first connecting part 361 is configured as a slot / hole extending along the first direction / left-right direction.

[0200] Continue as ​ and ​As shown, the chip socket 3 also includes a connector 370 that connects the chip mounting portion 31 and the connecting portion 33. The connector 370 has a cutout portion 371. The cutout portion 371 allows the chip socket 3 to move backward relative to the housing 1. Furthermore, the chip socket 3 is made of an elastic material, such as silicone or rubber. In this embodiment, the chip socket 3 is made of silicone, so the chip socket 3 itself is elastic.

[0201] Before the developing cartridge 100 is installed in place, the chip holder 3 is set to be subjected to a forward bias force. In order to overcome the bias force and make the electrical contact portion 42 of the chip 4 and the electrical contact pin 004 electrically connected / made contact, as follows: ​ and ​ As shown, the chip holder 3 is also provided with a limiting part 313. In the front-rear direction, the limiting part 313 is located in front of the chip mounting part 31. During the installation of the developing cartridge 100, the limiting part 313 is used to abut against the front side 0024 of the guide rail (as shown in Figure 2). As the developing cartridge 100 is further installed, the chip holder 3 overcomes the forward biasing force and moves backward relative to the housing 1. Under the elastic force of the chip holder 3 itself, the chip holder 3 has a tendency to move forward and / or upward, thereby ensuring the stability of the electrical connection / contact between the electrical contact part 42 / chip 4 and the electrical contact pin 004. Furthermore, when the cutout part 371 is provided, the rearward deformation of the connector 370 of the chip holder 3 is greater, which is more conducive to the stability of the electrical connection / contact between the electrical contact part 42 and the electrical contact pin 004.

[0202] like ​ and ​ As shown, the cover 21 includes a cover body 210, a first connected portion 218a disposed on the cover body 210, and an enclosing portion 217. The first connected portion 218a is used to cooperate with the first connecting portion 361 of the chip holder 3 to install the chip holder 3. Specifically, the first connected portion 218a can be configured as a slot / hole structure or a protrusion / shaft structure. In this embodiment, the first connecting portion 361 is configured as a slot / hole extending along a first direction / left-right direction. Therefore, the first connected portion 218a is configured as a shaft protruding from the cover body 210 along the first direction / left-right direction in a direction away from the housing 1 (driving end C1) to cooperate with the slot / hole 361. Further, the first connected portion 218a is configured as a mating shaft with at least one plane, and the first connecting portion 361 is configured as a mating slot / hole of corresponding shape. In this way, the chip holder 3 will not rotate around the first connected portion 218a, which is more conducive to the stability of the electrical connection / contact between the electrical contact portion 42 and the electrical contact pin 004.

[0203] Continue as ​ and ​As shown, the enclosure portion 217 extends from the cover body 210 along a first direction / left-right direction away from the housing 1 (driving end C1) and forms an enclosure space 217a. The enclosure space 217a is used to enclose the abutment member 337 of the connecting portion 33. Furthermore, the enclosure space 217a is configured to correspond to the shape of the abutment member 337 to further prevent the chip holder 3 from rotating around the first connected portion 218a, thereby further ensuring the stability of the electrical connection / contact between the electrical contact portion 42 and the electrical contact pin 004. The enclosure portion 217 is also provided with a non-closed portion 217b, which is used to prevent the chip holder 3 from being too tightly attached to the cover 21 and thus unable to be disassembled.

[0204] Example 12

[0205] ​ and ​ This is a perspective view of the hidden components of the developing cartridge according to Embodiment Twelve of this utility model; ​ This is an exploded view of some components of the developing cartridge according to Embodiment Twelve of this utility model; ​ This is a schematic diagram of some components of the chip assembly involved in Embodiment Twelve of this utility model.

[0206] like ​ and ​ , ​ and ​ As shown, in this embodiment, at least a portion of the chip assembly is separately formed from the cover 21 / housing 1. Specifically, the chip assembly includes at least a chip holder 3 and a chip 4 disposed on the chip holder 3. Preferably, the chip holder 3 is separately formed from the cover 21 / housing 1 and is movable relative to the cover 21 / housing 1, and the chip 4 is disposed on the chip holder 3. In some embodiments, the chip holder 3 is integrally formed with the cover 21 / housing 1.

[0207] Furthermore, the chip 4 includes at least a chip substrate 41 and an electrical contact portion 42 disposed on the chip substrate 41. The electrical contact portion 42 is used for electrical connection / contact with the electrical contact pin 004. When the developing cartridge 100 is installed in the imaging device, the electrical contact surface 421a of the electrical contact portion 42 or the chip substrate 41 is parallel to the upper surface 0023 of the guide rail to increase the stability when the electrical contact portion 42 is electrically connected / contacted with the electrical contact pin 004. During the installation of the developing cartridge 100, the chip 4 is prevented from being scraped off by the electrical contact pin 004. Preferably, a straight line is drawn through the contact position between the electrical contact pin 004 and the electrical contact surface 421a or the chip substrate 41, and perpendicular to the electrical contact surface 421a or the chip substrate 41. This straight line is parallel to the third direction / up and down direction.

[0208] Furthermore, the chip assembly includes a sponge 391 (an embodiment of the chip holder 3). Because the sponge 391 is elastic, it is movable relative to the cover 21 / housing 1 in a third direction / vertical direction. In this embodiment, the chip 4 is disposed on the sponge 391. Specifically, the sponge 391 has an upper receiving space 391a for receiving the chip 4. In the third direction / vertical direction, the receiving space 391a is recessed downward relative to the upper end of the sponge 391. At this time, in the second direction / front-back direction, a first protective portion 392a is formed in front of the receiving space 391a, and a second protective portion 392b is formed behind the receiving space 391a. Along the front-to-back direction, the first protective portion 392a, the receiving space 391a, and the second protective portion 392b are connected. b. The first protective part 392a and the second protective part 392b are arranged sequentially to abut against the first blocked part 411a of the chip 4. When the chip 4 is accommodated by the accommodating space 391a, in the third direction / up-down direction, the first protective part 392a protrudes upward from the end of the chip 4, that is, the electrical contact surface 421a of the electrical contact part 42, to prevent the chip 4 from being scraped off during the installation of the developing cartridge 100. The second protective part 392b may protrude from the end of the chip 4 or be flush with the end of the chip 4. In some embodiments, the first protective part 392a may also be set to be flush with the end of the chip 4. Furthermore, in the first direction / left-right direction, there is a gap g between the sponge 391 and the end face of the cover 21 on the side away from the housing 1. The gap g allows the sponge 391 to have room for movement, thereby improving the automatic adjustment capability of the chip holder 3.

[0209] Furthermore, the cover 21 is provided with a support base, which has a concave space 393 and an upward-facing end face 394. At least a portion of the sponge 391 is accommodated in the concave space 393. The sponge 391 is disposed in the concave space 393. Since the sponge 391 has a deformation amount in the third direction / up and down direction, it will be squeezed downward when it abuts against the guide rail during the installation of the developing cartridge 100. Therefore, the sponge 391 is configured to protrude from the end face 394 in the third direction / up and down direction. Furthermore, in the third direction / up and down direction, when the electrical contact part 42 is electrically connected / in contact with the electrical contact pin 004, the protrusion amount of the sponge 391 protruding from the end face 394 is h1. The range of the protrusion amount h1 is 8mm-15mm, preferably, the range of the protrusion amount h1 is 9.5mm-13.5mm.

[0210] In some implementations, silicone or rubber components may be used instead of sponge components.

[0213] like ​ , ​ , ​ , ​ , ​ , ​ and ​ As shown, in this embodiment, the chip assembly and the cover 21 / housing 1 are separately formed. The chip assembly includes at least a chip holder 3, a chip 4 disposed on the chip holder 3, and a second elastic member 395. The chip holder 3 is rotatable relative to the cover 21 / housing 1 about a rotation axis L2 intersecting the second direction / front-back direction (coaxial with the first connected portion 218a described later). The second elastic member 395 is used to provide a reset force to the chip holder 3. The structure of the chip 4 can be referred to the description in Embodiment Eleven.

[0214] The chip mount 3 includes at least a chip mounting portion 31 and a connecting portion 33. Further, the structure of the chip mounting portion 31 can be referred to the description in Embodiment 11. The connecting portion 33 has a first connecting portion 361 and a second connecting portion 362. The first connecting portion 361 and the second connecting portion 362 are used to mount the chip mount 3 onto the cover 21. Specifically, the first connecting portion 361 is used to cooperate with the first connected portion 218a provided on the cover 21, and the second connecting portion 362 is used to cooperate with the first end 395a of the second elastic member 395. The cover 21 is also provided with… The second connected portion 218b is used to engage with the second end 395b of the second elastic member 395. That is, the elastic member 395 connects the second connecting portion 362 and the second connected portion 218b. The elastic member 395 can be configured as a tension spring, compression spring, torsion spring, elastic cord, etc. Preferably, the elastic member 395 is a tension spring. After the chip holder 3 is installed into the developing cartridge 100, before the developing cartridge 100 is installed, in its natural state, when viewed along a third direction / up / down direction, the chip substrate 41 overlaps with the rotation axis L2 (e.g., ...). ​(As shown). Furthermore, the first connected portion 218a and the second connected portion 218b are configured to protrude from the cover body 210 toward the drive end C1 along a first direction / left-right direction.

[0215] Furthermore, the first connecting portion 361 includes an outer circular portion 381 and an inner circular portion 382. More specifically, along the first direction / left-right direction, a first latching portion 218a1 is provided at the left end of the first connected portion 218a. The first latching portion 218a1 is used to engage with the left end of the inner circular portion 382. When the first latching portion 218a1 engages with the left end of the inner circular portion 382, ​​the chip holder 3 is locked, thereby preventing the chip holder 3 from falling off the cover 21. In the first direction / left-right direction, the left end of the inner circular portion 382 is closer to the left end of the outer circular portion 381. In the first direction / left-right direction, the first latching part 218a1 does not protrude from the outer circle part 382. When the first latching part 218a1 engages with the inner circle part 382, ​​it can prevent the first latching part 218a1 from interfering with the components in the imaging device, thus preventing the developing cartridge 100 from being installed smoothly. Furthermore, the inner circle part 382 is provided with a notch part 3821. When the chip holder 3 rotates to the point where the notch part 3821 is opposite to the first latching part 218a1, the locking of the chip holder 3 is released, and the chip holder 3 can be removed from the cover 21.

[0216] Furthermore, a second latching part 3621 is provided at the left end of the second connecting part 362, and a third latching part 218b1 is provided at the left end of the second connected part 218b. When the second elastic member 395 connects the second connecting part 362 and the second connected part 218b, the second latching part 3621 and the third latching part 218b1 are used to prevent the second elastic member 395 from falling off.

[0217] Furthermore, the first connecting portion 361 and the first connected portion 218a are engaged by a shaft hole. Specifically, the first connecting portion 361 can be configured as a slot / hole extending along the first direction / left-right direction, and the first connected portion 218a can be configured as a protrusion / shaft protruding towards the drive end C1 along the first direction / left-right direction. Alternatively, the first connecting portion 361 can be configured as a protrusion / shaft extending along the first direction / left-right direction, and the first connected portion 218a can be configured as a slot / hole extending along the first direction / left-right direction.

[0218] The chip holder 3 also includes a connector 370 and a spacer 34. The connector 370 has a cutout portion 371 and a second cutout portion 371b. In the first direction / left-right direction, the cutout portion 371 is located to the left of the second cutout portion 371b, that is, the cutout portion 371 is further away from the housing 1 / cover 21 than the second cutout portion 371b. In the first direction / left-right direction, the spacer 34 is located to the right / right end of the chip mounting portion 31, that is, the spacer 34 is closer to the housing 1 / cover 21 than the chip mounting portion 31. Furthermore, when the developing cartridge 100 is installed in the imaging device, the spacer 34 is used to accommodate / avoid the positioning protrusion 0022 in the imaging device, so that the positioning protrusion 0022 restricts the movement of the chip holder 3 in the first direction / left-right direction, thereby making the electrical connection / contact between the chip 4 and the electrical contact pin 004 more stable.

[0219] like ​ As shown, when the developing cartridge 100 is installed into the imaging device, the chip holder 3 is pushed by the guide rail to rotate along the direction r1, thereby making the electrical contact portion 42 of the chip 4 electrically connected / in contact with the electrical contact pin 004. At the same time, the second elastic member 395 is stretched, and the chip holder 3 has a tendency to rotate in the opposite direction to the direction r1, thereby making the electrical connection / in contact between the electrical contact portion 42 of the chip 4 and the electrical contact pin 004 more stable. At this time, when viewed along the third direction / up and down direction, the rotation axis L2 is located in front of at least a part of the electrical contact portion 42.

[0220] When the developing cartridge 100 is removed from the imaging device, the chip holder 3 is reset by rotating in the opposite direction to the direction r1 under the elastic force of the second elastic element 395.

[0221] Furthermore, in this embodiment, the chip socket 3 can be made of a soft elastic material or a hard material, and there is no limitation on this.

[0222] In some imaging devices, the positioning protrusion 0022 for guidance is not provided, and in this case, the chip holder 3 may not have the spacer 34.

[0223] Examples 11 to 13, by setting the chip holder to be deformable or biasable, prevent the chip holder from colliding with other components in the imaging device and being damaged during the installation of the developing cartridge, thereby protecting the chip holder. In addition, it also makes the installation of the developing cartridge smooth.

[0224] In the above embodiments, the developing cartridge 100 can be directly installed to the imaging device, or it can be first installed to the drum stand 900 and then installed to the imaging device together with the drum stand 900.
