[0002] The toner cartridge is a component that can be installed in an image forming device and replenishes developer for the image forming device. The toner cartridge usually includes a storage component for storing information related to the toner cartridge (e.g., the type of the toner cartridge, the capacity of the developer, the amount of the remaining developer, the color of the developer, etc.), and during the operation of the image forming device, the toner cartridge establishes a communication connection with the image forming device and transmits the related information to the image forming device.

[0003] In the related art, the toner cartridge usually establishes a communication connection with the image forming device by driving the electrical contacts of the storage component to rise to the position of the electrical contacts of the image forming device and to be electrically connected with the electrical contacts of the image forming device.

[0047] In order to make the purpose of the embodiments of the present application, the technical scheme and the technical effect more clear, the technical scheme of the toner cartridge of the present application will be described clearly and completely in combination with the drawings. Obviously, the described embodiments are only a preferred embodiment of the present application, not all embodiments, based on the embodiments of the present application, other embodiments obtained by the skilled in the art without creative labor, all belong to the protection scope of the present application.

[0048] Embodiment 1:

[0049] Please refer to Figures 1 to 14 The present application provides a toner cartridge 100 which can be installed in an image forming device (not shown), the toner cartridge 100 can establish a communication connection with the image forming device, so as to send the relevant information (for example, the type of the toner cartridge 100, the capacity of the developer, the amount of the remaining developer, the color of the developer, etc.) of the toner cartridge 100 to the image forming device, and receive the control instruction of the image forming device through the established communication connection. Specifically, the image forming device comprises a first electrical contact 201, the storage assembly 20 which stores the relevant information of the toner cartridge 100 comprises a second electrical contact 21, and the toner cartridge 100 realizes the communication connection with the image forming device through the electrical connection between the first electrical contact 201 and the first electrical contact 201 of the image forming device.

[0050] As Figure 1 and Figure 2As shown, the toner cartridge 100 includes a housing 10, which is a cavity structure such as a box or case. A handle may be provided on the housing 10 for user convenience. The housing 10 has a first receiving cavity 11 for containing developer and a first opening 12 communicating with the first receiving cavity 11, through which the developer can exit the toner cartridge 100. The housing 10 has a first side 13 and a second side 14 separated from the first side 13 in a first direction, which is the extending direction of the housing 10. A first end cap 15 is detachably connected to the first side 13 of the housing 10, and a second end cap 16 is detachably connected to the second side 14 of the housing 10. In a direction intersecting the first direction, the housing 10 has a third side 101 and a fourth side 102 oppositely disposed. Preferably, the third side 101 is the front side of the housing, and the fourth side 102 is the rear side of the housing.

[0051] like Figure 2 , Figures 12 to 14 As shown, the delivery assembly 80 is rotatably supported between the first side 13 and the second side 14 of the housing 10. One end of the delivery assembly 80 is located at the first opening 12. During the process of adding developer to the imaging device by the toner cartridge 100, the delivery assembly 80 can rotate about its own first axis A1 to directionally deliver the developer to the location of the first opening 12.

[0052] The stirring rack 110 is rotatably supported between the first side 13 and the second side 14 of the housing 10. The stirring rack 110 is used to stir the developer in the first receiving cavity 11 to prevent the developer from clumping. The stirring rack 110 includes a stirring rack shaft 111, which is rotatable about its own second axis A2.

[0053] The gear system of the toner cartridge 100 is rotatably supported within the space formed between the first side 13 and the first end cover 15 of the housing 10. The gear system may include a drive gear 120, a stirring frame gear 110, an input gear, and several intermediate gears 130. The drive gear 120 receives external driving force from the toner cartridge 100 and drives the other gears to rotate. The stirring frame gear 112 is connected to one end of the stirring frame shaft 111 and meshes with the drive gear 120. When the drive gear 120 rotates, it drives the stirring frame gear 112 to rotate, which in turn drives the stirring frame shaft 111 to rotate. The stirring frame shaft 111 then drives the stirring frame 110 to rotate, and the rotating stirring frame 110 can stir the developer in the first receiving cavity 11. The conveying gear 81 is connected to one end of the conveying assembly 80. The conveying gear 81 may directly mesh with the stirring frame gear 112 or the drive gear 120, or indirectly mesh with the stirring frame gear 112 or the drive gear 120 through several intermediate gears 130. When the drive gear 120 rotates, the conveying gear 81 rotates in tandem with the drive gear 120. When the conveying gear 81 rotates, it can drive the conveying assembly 80 to rotate around the first axis A1, thereby conveying the developer inside the housing 10 in a directional manner.

[0054] like Figure 1 and Figure 2 As shown, the storage component 20, electrical connector 30 and linkage component 40 of the toner cartridge 100 are located on the second side 14 of the housing 10 and are located in the space between the second end cover 16 and the side wall of the second side 14 of the housing 10.

[0055] The linkage assembly 40 is used to receive the driving force of the actuating component (not shown, e.g., a door cover) of the imaging device. Specifically, the linkage assembly 40 has a mating surface 401 facing the fourth side 102 of the housing 10. The actuating component of the imaging device can approach and act on the mating surface 401. The storage assembly 20 includes a circuit board 22 and a second electrical contact 21 connected to the circuit board 22. Under the action of the actuating component of the imaging device, the linkage assembly 40 can drive the storage assembly 2 to a first position (e.g., on the second side 14 away from the housing 10) along a first direction. Figure 3 As shown), and the second position near the second side 14 of the housing 10 (as shown). Figure 4 As shown, when the storage component 20 moves to the second position, the second electrical contact 21 is electrically connected to the first electrical contact 201 of the imaging device; the electrical connector 30 is a conductive component, and its first end 31 is connected to the second electrical contact 21 of the storage component 20. The electrical connector 30 can move along with the storage component 20. Here, the first position is closer to the first side 13 of the housing 10 than the second position.

[0056] In the initial state when the toner cartridge 100 is installed to the image forming device and the door cover is not closed, the storage assembly 20 is located at the first position away from the second side 14 of the housing 10, at this time, the first end 31 of the electrical connecting member 30 abuts against the second electrical contact 21 of the storage assembly 20, the second end 32 of the electrical connecting member 30 does not abut against the first electrical contact 201 of the image forming device, the communication between the toner cartridge 100 and the image forming device is disconnected. After the door cover of the image forming device is closed, the door cover acts on the engaging surface 401 of the linkage assembly 40, drives the linkage assembly 40 to move, the linkage assembly 40 drives the storage assembly 20 to gradually move from the first position away from the second side 14 of the housing 10 to the second position close to the second side 14 of the housing 10. During the movement, the second electrical contact 21 on the storage assembly 20 moves along with the storage assembly 20 and transmits the driving force to the first end 31 of the electrical connecting member 30 to drive the electrical connecting member 30 to also move along with the movement of the storage assembly 20 and move towards the position where the first electrical contact 201 is located. When the storage assembly 20 moves to the second position close to the second side 14 of the housing 10, the second end 32 of the electrical connecting member 30 abuts against the first electrical contact 201 of the image forming device, at this time, the two ends of the electrical connecting member 30 abut against the first electrical contact 201 of the image forming device and the second electrical contact 21 of the toner cartridge 100 respectively, and the communication connection between the toner cartridge 100 and the image forming device is established.

[0057] Optionally, the toner cartridge 100 further comprises an elastic member 44, the elastic member 44 is used to bias the engaging surface 401 of the linkage assembly 40 towards the fourth side 102 of the housing 10. When the door cover of the image forming device is opened, the door cover no longer acts on the engaging surface 401 of the linkage assembly 40, the linkage assembly 40 can move to the initial position under the action of the elastic member 44, the linkage assembly 40 drives the storage assembly 20 to move from the second position close to the second side 14 of the housing 10 to the first position away from the second side 14 of the housing 10 when the linkage assembly 40 moves. Specifically, one end of the elastic member 44 is connected to the second end cover 16 or the side wall of the second side 14 of the housing 10, the other end of the elastic member 44 is connected to the linkage assembly 40, the elastic member 44 is elastically deformed and stores elastic potential energy during the process that the actuating component acts on the linkage assembly 40 and the linkage assembly 40 drives the storage assembly 20 to move to the second position close to the second side 14 of the housing 10, when the actuating component does not act on the linkage assembly 40, the elastic member 44 releases the elastic potential energy and drives the linkage assembly 40 to return to the initial position, the linkage assembly 40 drives the storage assembly 20 to move towards the first position away from the second side 14 of the housing 10.

[0058] Here, the first end 31 of the electrical connecting piece 30 is connected to the second electrical contact 21 of the toner cartridge 100, the linkage assembly 40 can drive the storage assembly 20 to move between the first position away from the second side 14 of the housing 10 and the second position close to the second side 14 of the housing 10, and when the storage assembly 20 moves to the second position, the second end 32 of the electrical connecting piece 30 gradually approaches the first electrical contact 201 of the image forming device and finally connects with the first electrical contact 201, thereby realizing the communication connection between the toner cartridge 100 and the image forming device. The second electrical contact 21 of the toner cartridge 100 will not rub with the first electrical contact 201 of the image forming device, and at the same time, the second end 32 of the electrical connecting piece 30 will only abut with the first electrical contact 201 of the image forming device and will not rub and move along the surface of the first electrical contact 201 of the image forming device, which can effectively reduce the wear of the second electrical contact 21 of the toner cartridge 100, the electrical connecting piece 30 and the first electrical contact 201 of the image forming device, and help to improve the reliability of the communication connection between the toner cartridge 100 and the image forming device.

[0059] As shown in Figure 2 , Figure 7 and Figure 8 , the linkage assembly 40 includes a driving part 41, a rotating part 42 and a moving part 43. When the actuating member acts on the linkage assembly 40, the driving part 41 on the linkage assembly 40 moves relative to the second side 14 of the housing 10. The rotating part 42 is connected to the driving part 41, and the driving part 41 drives the rotating part 42 to rotate when the driving part 41 moves. The moving part 43 is connected to the rotating part 42, and the rotating part 42 drives the moving part 43 to move when the rotating part 42 rotates. The moving direction of the moving part 43 is different from the moving direction of the driving part 41, and the moving directions of the two are at an angle. The storage assembly 20 is connected to the moving part 43, and the moving part 43 can drive the storage assembly 20 to move between the first position and the second position.

[0060] As an example, the driving part 41 and the rotating part 42 are configured as a crank and connecting rod structure, the driving part 41 is configured as a connecting rod, and the rotating part 42 is configured as a crank. The driving part 41 drives the rotating part 42 to rotate when the driving part 41 moves. The rotating part 42 and the moving part 43 are configured as a screw and nut structure, the rotating part 42 is configured as a screw, and the moving part 43 is configured as a nut. The rotating part 42 drives the moving part 43 to move when the rotating part 42 rotates.

[0061] As another example, the driving part 41 and the rotating part 42 are configured as a flexible belt and a roller structure, the driving part 41 is configured as a flexible belt, the rotating part 42 is configured as a roller, one end of the flexible belt is fixedly connected to the roller and wound on the circumferential surface of the roller, when the actuating component acts on the linkage assembly 40, the one end of the flexible belt is driven to gradually move away from the roller, and the flexible belt drives the roller to rotate in the process of moving away from the roller. The rotating part 42 and the moving part 43 are configured as a linear driving device, the rotating part 42 is configured as an input end of the linear driving device, and the moving part 43 is configured as an output end of the linear driving device. When the rotating part 42 rotates, the moving part 43 is driven to move linearly.

[0062] By adopting the above technical solutions, the rotating part 42 can rotate following the movement of the driving part 41, and the moving part 43 can drive the storage assembly 20 to move between the first position and the second position following the rotation of the rotating part 42. Through the coordination between the driving part 41 and the rotating part 42, and the coordination between the rotating part 42 and the moving part 43, the accurate movement of the storage assembly 20 between the first position and the second position can be realized, which helps to improve the stability and reliability of the toner cartridge 100.

[0063] Alternatively, as shown in Figures 2 to 4 、 Figure 7 and Figure 8 , the driving part 41 includes a rack 411, the rotating part 42 includes a gear part 421 and a first threaded part 422 connected to the gear part 421, and the moving part 43 includes a second threaded part 431.

[0064] The gear part 421 is adapted to the rack 411, the gear part 421 is engaged with the rack 411, and the gear part 421 can rotate following the movement of the rack 411. The gear part 421 can be configured as a full-tooth gear, or can be configured as a gear with partial teeth. The gear part 421 can include a first gear 4211 and a second gear 4212 engaged with the first gear 4211, the first gear 4211 is engaged with the rack 411, and the first threaded part 422 is connected to the second gear 4212.

[0065] The first threaded part 422 and the second threaded part 431 are adapted to each other, the second threaded part 431 is threadedly connected with the first threaded part 422, the first threaded part 422 can rotate following the rotation of the gear part 421, and the second threaded part 431 can drive the storage assembly 20 to move between the first position and the second position following the rotation of the first threaded part 422.

[0066] Specifically, after the toner cartridge 100 is installed to the image forming device, the actuating component of the image forming device acts on the engagement surface 401 of the linkage assembly 40, drives the rack 411 in the linkage assembly 40 to move relative to the sidewall of the second side 14 of the housing 10, the rack 411 drives the gear portion 421 to rotate when moving, the gear portion 421 drives the first threaded portion 422 fixedly connected thereto to rotate, the first threaded portion 422 rotates along the thread between the second threaded portion 431, so that the second threaded portion 431 gradually approaches the second side 14 of the housing 10, while driving the storage assembly 20 to gradually approach the second side 14 of the housing 10.
