[0094] The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be construed as being limited to the embodiments described herein. Instead, these embodiments are provided to provide a more thorough and complete understanding of the present application. It should be understood that the drawings and embodiments of the present application are only for exemplary purposes and are not intended to limit the scope of protection of the present application.

[0095] It should be understood that the various steps described in the method implementation of the present application can be performed in different orders and / or performed in parallel. In addition, the method implementation may include additional steps and / or omit the steps shown. The scope of the present application is not limited in this respect.

[0096] The term "including" and its variations used in this document are open inclusions, that is, "including but not limited to". The term "based on" means "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment"; the term "some embodiments" means "at least some embodiments". Relevant definitions of other terms will be given in the description below. It should be noted that the concepts of "first", "second", etc. mentioned in this application are only used to distinguish different devices, units or units, and are not used to limit the order or interdependence of the functions performed by these devices, units or units.

[0097] It should be noted that the modifications of "one" and "plurality" mentioned in the present application are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0098] The image forming device may be a printer, a copier, etc., in which the box and the main body are separated, and the electrical contacts of the main body need to be in contact with the box through the identification unit to achieve communication connection between the image forming device and the box. After the main body is in electrical contact with the identification unit through the electrical contacts of the main body, the identification unit identifies that the box is installed in place, or identifies whether the installed box is an original box. Only after the identification is completed can the normal image output operation be performed.

[0099] Taking an image forming device using a toner cartridge as an example, a chip can be installed on the toner cartridge. When a user manually pushes the toner cartridge into the image forming device, the chip installed on the toner cartridge can contact the electrical contacts of the main component of the image forming device through sliding friction. The inventors have found that during the sliding friction between the chip installed on the toner cartridge and the electrical contacts of the main component of the image forming device, it is easy to cause wear on the chip installed on the toner cartridge. For example, when a user uses a large thrust to push the toner cartridge into the image forming device, it is very easy to wear the chip installed on the toner cartridge, causing scratches on the chip on the toner cartridge, thereby reducing the life of the chip and further affecting the printing quality.

[0100] In view of the above problems, an embodiment of the present application provides a cartridge, which includes a transmission mechanism, which can push the identification unit to contact the electrical contacts of the main component, so as to reduce the risk of wear and scratching the identification unit and increase the service life of the identification unit while ensuring normal communication between the cartridge and the image forming device. The cartridge here can be a toner cartridge with a toner cartridge, etc.

[0101] Figure 1 An exploded schematic diagram of a transmission mechanism according to an embodiment of the present application is shown. Figure 2 FIG. 1 is a schematic diagram showing a transmission mechanism according to an embodiment of the present application. Figure 1 and Figure 2As shown, the transmission mechanism disclosed in the embodiment of the present application includes a support module 101, a first thrust mechanism 102 and a driving module 103. It should be understood that various possible descriptions of the relevant structures and functions of the transmission mechanism involved below can be applicable to the functional realization of the box.

[0102] Figure 3A It shows a schematic diagram of the structural state of the transmission mechanism installed in the box in the embodiment of the present application when the identification unit is in the initial position, Figure 3B A schematic diagram of the structure state of the transmission mechanism installed in the box in the embodiment of the present application when the identification unit is located at the target position is shown. Figure 3A and Figure 3B As shown, the first thrust mechanism 102 is used to push the bracket module 101. The driving module 103 is in transmission connection with the first thrust mechanism 102. At this time, the driving module 103 is used to drive the first thrust mechanism 102, so that the first thrust mechanism 102 pushes the bracket module 101 to drive the identification unit A to move from the initial position to the target position within a preset time, thereby achieving contact between the identification unit A and the electrical contact B of the main component.

[0103] In some embodiments, Figure 1 and Figure 2 As shown, when the identification unit A includes a storage medium, the storage medium includes a storage element and an electrical contact surface. The storage unit can be a read-only memory, an access memory, etc. The specific type can refer to the relevant technology and will not be described in detail here.

[0104] The electrical contact surface can be electrically connected to a storage unit. The storage element is used to store information about the cartridge, such as cartridge specifications, toner type, manufacturer, etc. The contact surface is used to electrically connect to an electrical contact B of a main component of an image forming device, so that the image forming device reads the relevant information stored in the storage unit through the electrical contact B of the main component and the contact surface of the storage unit to determine whether the cartridge meets the requirements of the image forming device. It can be seen that the storage medium can be used as an electrical detection unit installed on the cartridge to assist the image forming device in completing cartridge information detection.

[0105] In some embodiments, Figure 1 and Figure 2 As shown, the identification unit A can be a conductive unit, which is used to be electrically connected to the electrical contact B of the main component of the image forming device. For example, the conductive unit can be a high-voltage contact of the imaging member, and the image forming device can normally power the cartridge by the electrical contact B of the main component in contact with the high-voltage contact.

[0106] In some embodiments, Figure 1 and Figure 2As shown, the identification unit A is an adapter electrically connected to the chip of the box. For example, the chip of the box may refer to the storage medium mentioned above, or may refer to a microchip with computing processing capabilities. When the image processing device is electrically connected to the adapter through the electrical contact B of the main component, and the electrical contact B is further indirectly electrically connected to the box chip, the box chip does not have to be limited to the position of the electrical contact B of the main component, and the position setting can be more flexible. Moreover, even if the adapter is worn to a certain extent due to long-term use, it only needs to be replaced, thereby effectively reducing costs.

[0107] like Figure 1 and Figure 2 As shown, the identification unit A may have multiple communication terminals, each of which forms a conductive contact, and the multiple conductive contacts include a VCC contact, an SDA contact, a GND contact, and an SCL contact. The VCC contact is used to contact and conduct with an external power supply unit to obtain the voltage required for the cartridge chip to work, the SDA contact is a data communication contact, the GND contact is a ground contact, and the SCL contact is a clock signal contact. These four conductive contacts are respectively in contact with the corresponding electrical contacts B of the main assembly on the image forming device, thereby realizing the electrical connection between the image forming device and the cartridge chip.

[0108] In practical applications, such as Figure 3A and Figure 3B As shown, when the first thrust mechanism 102 pushes the bracket module 101 to move, the identification unit A supported by the bracket module 101 can contact the electrical contact B of the main component of the image forming device in a surface-to-surface contact manner. At this time, there is no need for sliding friction between the identification unit A supported by the bracket module 101 and the electrical contact B of the main component of the image forming device, but the contact is achieved in a surface-to-surface contact manner. Therefore, the technical solution of the embodiment of the present application can reduce the probability of wear and scratches on the identification unit A, thereby increasing the service life of the identification unit A. Moreover, when the first thrust mechanism 102 pushes the bracket module 101 to drive the identification unit A to move from the initial position to the target position within a preset time, the first thrust mechanism 102 can apply a force to the bracket module 101, so that the identification unit A is in close contact with the electrical contact B of the main component.

[0109] like Figure 3A As shown, the initial position may refer to the position of the identification unit A supported by the bracket module 101 when the identification unit A is not in contact with the electrical contact B of the main component. Figure 3BAs shown, the target position may refer to the position of the identification unit A when the identification unit A contacts the electrical contact B of the main component. The driving module 103 may be controlled manually or mechanically to drive the first thrust mechanism 102, so that the first thrust mechanism 102 pushes the bracket module 101 within a preset time to drive the identification unit A to move from the initial position to the target position.

[0110] In some embodiments, Figure 3A and Figure 3B As shown, after the user places the cartridge in the image forming device, the position of the identification unit A in the image forming device can be defined as the first initial position. When it is detected that the cartridge is placed in the image forming device, the driving module 103 can be controlled to drive the first thrust structure to push the bracket module 101 within a preset time, so that the bracket module 101 drives the identification unit A to move from the initial position to the target position. When the identification unit A reaches the target position, the identification unit A can be in the position where it contacts the electrical contact B of the main component.

[0111] In other embodiments, Figure 3A and Figure 3B As shown, after the image forming device forms an image (for example, the printer performs a printing operation), if the bracket module 101 drives the recognition unit A to retreat from the target position to a certain position, so that the recognition unit A is separated from the electrical contact B of the main component, but has not returned to the first initial position, the position where the recognition unit A is located is defined as the second initial position. At this time, the second initial position is located between the first initial position and the target position.

[0112] When the image forming device performs the next image formation, Figure 3A and Figure 3B As shown, the first thrust mechanism 102 can be driven by the driving module 103 so that the first thrust mechanism 102 pushes the bracket module 101 within a preset time period to drive the identification unit A to move from the initial position to the target position, thereby allowing the identification unit A to re-contact the electrical contact B of the main component.

[0113] In some possible implementations, such as Figure 3A and Figure 3B As shown, the first thrust mechanism 102 may be a forced push member, which drives the forced push member to push the bracket module 101 to drive the identification unit A to move from the initial position to the target position along a straight line within a preset time period through the driving module 103.

[0114] In practical applications, such as Figure 1 , Figure 2 , FIG. 3A to FIG. 3BAs shown, the forced push member can be a linear motion mechanism. Exemplarily, the forced push member is a reciprocating linear motion mechanism such as a piston or a linear guide rail, and the support module 101 is arranged at the moving end of the reciprocating linear motion mechanism, such as the end of the piston or the slider of the linear guide rail. The drive module can be a pneumatic drive mechanism, an electric drive mechanism or a hydraulic drive mechanism. Therefore, the drive module 103 can drive the reciprocating linear motion mechanism to perform linear reciprocating motion, so that the reciprocating linear motion mechanism can push the support module 101 to reciprocate between the initial position and the target position.

[0115] like Figure 1 , Figure 2 , FIG. 3A to FIG. 3B As shown, when the reciprocating linear motion mechanism pushes the bracket module 101 to drive the identification unit A along Figure 2 The recognition unit A moves linearly from the initial position to the target position from right to left, so that the recognition unit A contacts the electrical contact B of the main component. When the recognition unit A and the electrical contact B of the main component need to be separated, the driving module 103 controls the piston to perform linear reciprocating motion, so that the reciprocating linear motion mechanism can push the bracket module 101 to drive the recognition unit A along the Figure 2 The identification unit A is moved linearly from the target position to the initial position in the direction from left to right, thereby separating the electrical contact B of the main assembly from the identification unit A.

[0116] It is understandable that if Figure 1 , Figure 2 , FIG. 3A to FIG. 3B As shown, whether the identification unit A is along Figure 2 Move from the initial position to the target position in a straight line from right to left, or recognize unit A along Figure 2 Move in a straight line from the target position to the initial position from left to right. The initial position may be the first initial position described above or the second initial position described above.

[0117] In some possible implementations, such as FIG. 3A to FIG. 3B As shown, when the box includes an imaging member, the driving module 103 can be used to rotate along the imaging member to drive the first thrust mechanism 102 to push the bracket module 101 to drive the identification unit A to move from the initial position to the target position within a preset time.

[0118] The rotational motion can be a forward rotational motion or a reverse rotational motion of the imaging member. Here, the forward rotational motion can be set to be the same as the rotational direction of the imaging member, and the reverse rotational motion of the imaging member is different from the reverse direction of the imaging member.

[0119] In practical applications, such as FIG. 3A to FIG. 3BAs shown, the driving module 103 of the embodiment of the present application can convert the rotational motion into the linear motion, so that the driving module 103 can use the linear motion to push the bracket module 101 to move linearly. In this process, whether it is the forward rotational movement or the reverse rotational movement of the imaging member, within the preset time, the first thrust mechanism 102 can be used to push the bracket module 101 to drive the recognition unit A to move from the initial position to the target position along the axis direction of the imaging member, so that the recognition unit A contacts the electrical contact B of the main component.

[0120] like FIG. 3A to FIG. 3B As shown, when the recognition unit A moves from the initial position to the target position along the axis direction of the imaging member, the recognition unit A can gradually contact the electrical contact B of the main component along the direction perpendicular to the surface of the electrical contact B of the main component until the recognition unit A contacts the electrical contact B of the main component. This contact mode not only realizes surface-to-surface contact, but also does not generate sliding friction with the electrical contact B of the main component, which can effectively alleviate the problem of scratching and wearing the recognition unit A, thereby extending the life of the recognition unit A.

[0121] like Figure 3A and Figure 3B As shown, taking the end surface M of the imaging component away from one end of the bracket module 101 as a reference, when the recognition unit A is located at the initial position, the distance between the bracket module 101 and the end surface M of the imaging component is L1; when the recognition unit A is located at the target position, the distance between the bracket module 101 and the end surface M of the imaging component is L2, satisfying the relationship: L2>L1.

[0122] like Figure 3A and Figure 3B As shown, it can be Figure 3A and Figure 3B The middle right end face is the end face M of the imaging member, and the axial direction along the imaging member can be a direction perpendicular to the end face M of the imaging member. The distance between the end face M of the imaging member and the surface of the identification unit A at the initial position is set to be equal to L1, and the distance between the end face M of the imaging member and the surface of the identification unit A at the target position is set to be equal to L2.

[0123] like Figure 3A and Figure 3B As shown, when the first thrust mechanism 102 pushes the bracket module 101 to drive the identification unit A to move from the initial position to the target position within the preset time, it is actually a process in which the first thrust mechanism 102 pushes the bracket module 101 to drive the identification unit A away from the end surface M of the imaging component. Therefore, L1<L2.

[0124] It should be noted that if Figure 1 , Figure 2 , Figure 3A and Figure 3BAs shown, the side of the first bracket 1011 of the embodiment of the present application further has a reset structure 1016, and the first bracket 1011 is used to drive the identification unit A to move toward the direction close to the first thrust mechanism 102 when the reset structure 1016 is subjected to force. For example, the reset structure 1016 may include a reset surface located on the side of the first bracket 1011, and the reset surface is an inclined surface.

[0125] like Figure 1 , Figure 2 , Figure 3A and Figure 3B As shown, when the identification unit A needs to be separated from the electrical contact B of the main component, a pushing force can be applied to the inclined surface through the second thrust mechanism, and the pushing force has a component force in the axial direction of the imaging member on the inclined surface, and points to the direction of the first thrust mechanism 102, thereby pushing the first bracket 1011 to drive the identification unit A to move along the direction of the contact surface perpendicular to the electrical contact B of the main component. At this time, not only can the separation of the identification unit A and the electrical contact B of the main component be achieved, but also the friction between the identification unit A and the electrical contact B of the main component can be reduced to the maximum extent, thereby further alleviating the possibility of the identification unit A being worn and scratched, and improving the service life of the identification unit A.

[0126] In some embodiments, Figure 1 , Figure 2 , Figure 3A and Figure 3B As shown, the inclined surface can be set to a non-smooth surface, that is, the inclined surface can be set to a rough surface, so that the friction between the first thrust mechanism 102 and the inclined surface can be increased to increase the contact time between the first thrust mechanism 102 and the inclined surface, thereby more reliably realizing the separation of the identification unit A and the electrical contact B of the main component.

[0127] like Figure 1 , Figure 2 , Figure 3A and Figure 3B As shown, the first thrust mechanism 102 may be disposed on a movable structure in the image forming device, and the movable structure may be controlled manually or by the image forming device to separate the identification unit A from the electrical contact B of the main component. The movable structure here may refer to the implementation method of the above-mentioned forced pusher to push the reset surface of the reset structure 1016, so that the bracket module 101 may drive the identification unit A to move from the target position to the initial position, so as to achieve the purpose of retracting the identification unit A.

[0128] In some possible implementations, such as Figure 1 and Figure 2As shown, the bracket module 101 of the embodiment of the present application includes a first bracket 1011, and the first bracket 1011 is provided with a support surface, which is used to support the identification unit A, and the first thrust mechanism 102 can be located on a side of the first bracket 1011 away from the support surface.

[0129] In practical applications, Figure 4A FIG. 2 shows a schematic diagram of the three-dimensional structure of the first thrust mechanism of the embodiment of the present application. Figure 4A As shown, the driving module 103 includes a driving gear 1031, and the first thrust mechanism 102 includes a transmission gear 1021 and a pusher 1022. The transmission gear 1021 is used to mesh with the driving gear 1031, so that the driving gear 1031 can drive the transmission gear 1021 to rotate. The pusher 1022 is arranged on one side of the transmission gear 1021 and faces the end surface of the first bracket 1011. Therefore, the pusher 1022 can rotate with the rotation of the transmission gear 1021, and can push the first bracket 1011 during the rotation, so that the first bracket 1011 can drive the identification unit A to move from the initial position to the target position.

[0130] In an alternative approach, Figure 5A FIG. 1 shows a three-dimensional structural diagram of a support module 101 according to an embodiment of the present application. Figure 5A As shown, a force-bearing member 1012 is provided on the end surface of the first bracket 1011 facing the pushing member 1022. When the transmission gear 1021 is engaged with the driving gear 1031 and driven, the force-bearing member 1012 is pushed by the pushing member 1022, driving the first bracket 1011 to move in a direction away from the transmission gear 1021, so that the identification unit A moves from the initial position to the target position. Here, the pushing member 1022 and the force-bearing member 1012 can constitute a motion conversion mechanism, so that the rotational motion of the transmission gear 1021 can be converted into a linear motion of the force-bearing member 1012 moving along the axial direction of the imaging member.

[0131] For example, Figure 4A and Figure 5A As shown, the end surface of the pushing member 1022 facing the force-bearing member 1012 is provided with at least one toggle tooth P, and the end surface of the force-bearing member 1012 facing the pushing member 1022 is provided with at least one driven protrusion Q. The toggle tooth P is used to contact the side surface of the corresponding driven protrusion Q when the transmission gear 1021 is driven by the driving gear 1031, so as to push the force-bearing member 1012, so that the first bracket 1011 moves in a direction away from the transmission gear 1021, and the identification unit A moves from the initial position to the target position.

[0132] like Figure 4A and Figure 5AAs shown, since the pusher 1022 is disposed on one side of the transmission gear 1021 and faces the end surface of the first bracket 1011, when the transmission gear 1021 is driven by the driving gear 1031, the transmission gear 1021 rotates and drives the pusher 1022 to rotate. Since the pusher 1022 is provided with at least one shifting tooth P on the end surface facing the force receiving member 1012, the pusher 1022 can also drive the shifting tooth P to contact the side surface of the driven protrusion Q during the rotation process, so that the side surface of the shifting tooth P applies a force to the side surface of the corresponding driven protrusion Q, so that the driven protrusion Q transmits the force to the first bracket 1011 through the force receiving member 1012, so that the first bracket 1011 moves in a direction away from the transmission gear 1021, and drives the identification unit A to move from the initial position to the target position.

[0133] like Figure 4A and Figure 5A As shown, the side of the driven protrusion Q includes a first inclined surface Q1 and a first curved surface Q2. The first inclined surface Q1 and the first curved surface Q2 are connected continuously, and the continuous connection here may refer to that the first inclined surface Q1 is tangent to the first curved surface Q2. The side of the toggle tooth P includes a second inclined surface P1 and a second curved surface P2, and the second inclined surface P1 and the second curved surface P2 are connected continuously, and the continuous connection here may refer to that the second inclined surface P1 is tangent to the second curved surface P2. When the side of the toggle tooth applies a force to the side of the driven protrusion Q, the first inclined surface Q1 contacts the second inclined surface P1. At this time, the force has a component force pointing to the direction of the force-bearing member 1012 in the axial direction of the imaging member. Therefore, the driven protrusion Q can drive the first bracket 1011 to move in a direction away from the transmission gear 1021 through the force-bearing member 1012 under the toggle of the toggle tooth, and drive the identification unit A to move from the initial position to the target position.

[0134] For example, Figure 4A As shown, a plurality of tooth-like structures (such as three) can be provided on the end face of the pushing member 1022, and can be provided on the end face of the pushing member 1022 in a serrated shape along the circumferential direction of the pushing member 1022. Each tooth-like structure can be a symmetrical structure, and the two symmetrical sides of the tooth-like structure form a 45° angle.

[0135] like Figure 2 , Figure 4A and Figure 5A As shown, when the driving gear 1031 drives the transmission gear 1021 to rotate, since the two symmetrical sides of the tooth structure form a 45° angle, no matter the transmission gear 1021 rotates forward or reversely, the first bracket 1011 can be pushed through the end surface between the pushing member 1022 and the force-bearing member 1012, so that the first bracket 1011 drives the identification unit A to move from the initial position to the target position, thereby achieving contact between the identification unit A and the electrical contact B of the main component, thereby realizing normal communication.

[0136] In some embodiments, Figure 4B A cross-sectional schematic diagram showing a first thrust mechanism 102 installed on a frame according to an embodiment of the present application is shown. Figure 4C Another cross-sectional schematic diagram showing the first thrust mechanism 102 installed on the frame according to an embodiment of the present application, Figure 5B FIG. 1 is a cross-sectional schematic diagram of a bracket module 101 according to an embodiment of the present application. Figure 4A to Figure 4C , Figure 5A and Figure 5B As shown, the force-bearing member 1012 and the pushing member 1022 of the embodiment of the present application are both sleeve structures. The force-bearing member 1012 is provided with a first connecting member 1013, and the first connecting member 1013 is used to connect the frame 104 of the box. The first connecting member 1013 can move relative to the frame 104. The pushing member 1022 is provided with a second connecting member 1023, and the second connecting member 1023 is used to connect the frame 104 of the box, and the second connecting member 1023 can rotate relative to the frame 104.

[0137] like Figure 2 , Figure 4B , Figure 4C and Figure 5B As shown, when the force-bearing member 1012 is pushed by the pushing member 1022 and drives the first bracket 1011 to move in a direction away from the transmission gear 1021, the first connecting member 1013 will not be affected by the frame 104 when it is driven away from the frame 104 by the force-bearing member 1012. At the same time, since the second connecting member 1023 is arranged on the pushing member 1022, and the pushing member 1022 is arranged on one side of the transmission gear 1021 and faces the first bracket 1011, when the transmission gear 1021 is driven by the driving gear 1031 to perform a rotational movement, the second connecting member 1023 will also rotate. Since the second connecting member 1023 can rotate relative to the frame 104, during the rotation of the second connecting member 1023, the rotational movement of the second connecting member 1023 will not affect the frame 104, thereby realizing the motion decoupling between the second connecting member 1023 and the frame 104. It can be seen that when the first connecting member 1013 of the embodiment of the present application can move relative to the frame 104 and the second connecting member 1023 can rotate relative to the frame 104, the first connecting member 1013 can be movably connected to the frame 104 of the box in the axial direction of the imaging component, thereby ensuring that the identification unit A can move between the initial position and the target position.

[0138] Exemplarily, when the recognition unit A moves from the initial position along the axis direction of the imaging member between the initial position and the target position, the movement trajectory of the first bracket can be constrained to minimize the possibility of deviation of the movement trajectory of the recognition unit A. For example, the movement trajectory of the first bracket can be constrained by adding an end cap. The trajectory constraint principle of the end cap is described below in conjunction with the accompanying drawings.

[0139] Fig. 6A The schematic diagram of the structure of the end cover and the frame of the embodiment of the present application in the disassembled state is shown. Figure 6B FIG. 1 is a schematic diagram showing the structure of the end cap, frame and drive mechanism of an embodiment of the present application in an assembled state. Fig. 6A and Figure 6B As shown, the box of the embodiment of the present application further includes an end cover 106 , and the end cover 106 of the box is located on a side of the first thrust mechanism 102 close to the first bracket 1011 .

[0140] like Figure 2 , Figure 5A and Figure 5B As shown, the first bracket 1011 may also be provided with a limiting portion 1014. Fig. 6A and Figure 6B As shown, the end cover 106 has a window G for the first bracket 1011 and the limiting portion 1014 to pass through. The limiting portion 1014 is used to cooperate with the window G of the end cover 106 to limit the first bracket 1011 from rotating relative to the end cover 106.

[0141] like Figure 2 , Figure 3A , Figure 5A , Figure 5B , Fig. 6A and Figure 6B As shown, when the identification unit A is located at the initial position, the first bracket 1011 and the identification unit A provided on the supporting surface of the first bracket 1011 may be located in the window G of the end cover 106, or located on the side of the end cover 106 close to the first thrust mechanism 102. At this time, the end cover 106 may be equivalent to a protective cover for the bracket module 101, the first thrust mechanism 102 and the driving module 103.

[0142] like Figure 3B and Figure 6B As shown, when the identification unit A is located at the target position, the first bracket 1011 can extend from the end surface of the end cover 106 away from the first thrust mechanism 102 through the window G of the end cover 106, so that the identification unit A can contact the electrical contact B of the main component.

[0143] like Figure 2 , Figure 3A , Figure 5A , Figure 5B , Fig. 6Aand Figure 6B As shown, when the first thrust mechanism 102 pushes the bracket module 101 to drive the identification unit A to move from the initial position to the target position, the first bracket 1011 and the limiting portion 1014 provided on the first bracket 1011 can pass through the window G in the axial direction of the imaging member in a direction away from the first thrust mechanism 102. The window G can constrain the moving direction of the first bracket 1011 by cooperating with the limiting portion 1014, so as to ensure that the first bracket 1011 moves along the axial direction of the imaging member without rotating relative to the end cover 106.

[0144] In some embodiments, Figure 2 , Figure 3A , Figure 5A , Figure 5B , Fig. 6A and Figure 6B As shown, when the limiting portion 1014 is a columnar structure and is disposed on the upper end surface of the first bracket 1011, the window G may include a first window G1 and a second window G2, wherein the second window G2 is located above the first window G1 and is connected to the first window G1. The first window G1 allows the first bracket 1011 to pass through, and the second window G2 allows the limiting portion 1014 to pass through. In addition, the size and contour shape of the second window G2 may be matched with the size and contour shape of the limiting portion 1014 of the columnar structure, so as to ensure that when the limiting portion 1014 passes through the second window G2, the second window G2 may strictly constrain the moving track of the limiting portion 1014, so that the limiting portion 1014 moves along the axial direction of the imaging member as much as possible. Since the limiting portion 1014 is disposed on the first bracket 1011, even if the size of the first window G1 for the first bracket 1011 to pass through is relatively large, it is possible to ensure that the first bracket 1011 moves along the axial direction of the imaging member without causing the problem of the moving track deviating from the axial direction of the imaging member.

[0145] It can be seen that when the first bracket 1011 drives the identification unit A to move from the initial position to the target position along the axial direction of the imaging component under the push of the first thrust mechanism 102, the movement trajectory of the first bracket 1011 is constrained in the axial direction of the imaging component with the cooperation of the limiting portion 1014 and the window G, so that the identification unit A can be directly in contact with the electrical contact B of the main component without the problem of sliding friction contact, or the movement path of the identification unit A is offset, resulting in poor contact between the identification unit A and the electrical contact B of the main component, affecting the printing quality. When the first bracket 1011 drives the recognition unit A to move from the target starting position to the initial position along the axis direction of the imaging component, the movement trajectory of the first bracket 1011 is constrained in the axis direction of the imaging component under the cooperation of the limiting portion 1014 and the window G, so that the recognition unit A can be moved away from the electrical contact B of the main component along the direction perpendicular to the contact surface of the electrical contact B of the main component, so that there will be no sliding friction between the recognition unit A and the electrical contact B of the main component during the separation process, thereby reducing the possibility of scratches and wear of the recognition unit A and improving the service life of the recognition unit A. For example, Figure 5A and Figure 5B As shown, the first bracket 1011 is further provided with a guide portion 1015, and the guide portion 1015 is used to guide the first bracket 1011 to be installed to the frame 104. The guide portion 1015 can be installed on the end surface of the first bracket 1011 facing the first thrust mechanism 102.

[0146] like Figure 5B As shown, considering that the force-bearing member 1012 is a sleeve structure, the first connecting member 1013 and the guide portion 1015 can be arranged in the force-bearing member 1012, thereby improving the integration of the bracket module 101, facilitating the miniaturization of the bracket module 101, and reducing unnecessary space occupation. Since the end surface of the force-bearing member 1012 facing the pushing member 1022 is provided with at least one driven protrusion Q, and the force-bearing member 1012 is a sleeve structure, when the first connecting member 1013 and the guide portion 1015 are both arranged in the force-bearing member 1012, the first clamping portion K1, the first connecting member 1013 and the guide portion 1015 are all surrounded by the driven protrusion Q.

[0147] In one example, if Figure 4A and Figure 4CAs shown, the second connecting member 1023 can be a first L-shaped hook, which is used to connect to the first slot R1 of the frame 104, and the first L-shaped hook can move relative to the first slot R1. For example, when the frame 104 has a connecting shaft, the first slot R1 can be an annular groove opened on the outer side wall of the connecting shaft, and the hook of the first L-shaped hook can be hooked in the annular groove. Since the pusher 1022 of the second connecting member 1023 is arranged on one side of the transmission gear 1021 and faces the end surface of the first bracket 1011, the hook of the first L-shaped hook arranged on the second connecting member 1023 can rotate along the annular groove during the rotation of the second connecting member 1023, so that the second connecting member 1023 will not affect the frame 104 of the box during the rotation, and it can ensure that the second connecting member 1023 rotates more stably on the frame 104.

[0148] In some embodiments, Figure 2 As shown, the driving gear 1031 of the embodiment of the present application can be installed on the driving shaft 105, and the driving gear 1031 is provided with a third connecting member 1032. The third connecting member 1032 can be a second L-shaped hook. The second L-shaped hook is used to connect the second slot R2 of the driving shaft 105, and the second L-shaped hook can move relative to the second slot R2. Here, the second slot R2 can be an annular groove provided on the driving shaft 105, and the hook of the second L-shaped hook can be stuck in the second annular groove.

[0149] For example, when the driving gear 1031 is fixed on the driving shaft 105, the driving shaft can drive the driving gear 1031 to rotate during the rotation of the driving shaft. When the driving gear 1031 rotates along with the driving shaft, the second annular groove can guide the hook of the second L-shaped hook on the driving gear 1031 to prevent the driving gear 1031 from shaking during the rotation.

[0150] like Figure 2 As shown, the above-mentioned drive shaft 105 can be a drive shaft in the box. The drive shaft 105 can be a shaft added on the basis of relevant technology, or the existing rotating shaft in the box (such as the toner drum shaft) can be compatible with the function of the drive shaft 105, that is, the drive shaft 105 is compatible with the function of the existing rotating shaft in the box (such as the toner drum shaft).

[0151] For example, Figure 2 As shown, when the driving gear 1031 is rotatably disposed on the driving shaft 105, during the rotation of the driving gear 1031, the second annular groove can guide the second L-shaped hook disposed on the driving gear 1031, so that the driving gear 1031 will not affect the driving shaft 105 during the rotation. In this way, when the transmission mechanism is used in the box, it is only necessary to install the driving gear 1031 on the existing driving shaft 105, thereby simplifying the complexity of the box modification.

[0152] like Fig. 6A and Figure 6B As shown, when the existing rotating shaft in the box (such as the toner drum shaft) is compatible with the function of the driving shaft 105, a mounting hole H can be set on the end cover 106 of the box, and the driving shaft 105 is installed in the mounting hole H to ensure the installation stability of the driving shaft 105.

[0153] For example, Figure 2 As shown, the driving gear 1031 may be an electric driving gear 1031, or a battery may be provided on the driving gear 1031 or other parts to supply power to the driving gear 1031. Within a preset time period, the battery may supply power to the driving gear 1031, so that the driving gear 1031 drives the transmission gear 1021 to rotate within a preset time period, so that the pushing member 1022 provided on the transmission gear 1021 may push the force-bearing member 1012, so that the force-bearing member 1012 moves from the initial position to the target position within the preset time period.

[0154] For example, Figure 2 , Fig. 6A and Figure 6B As shown, an electronic switch can be configured for the battery, and the electronic switch can be controlled by the image forming device. If it is necessary to push the identification unit A to contact the electrical contact B of the main component, a reset signal can also be sent to the electronic switch through the image forming device, so that the electronic switch is turned on in response to the reset signal. In this way, the battery can supply power to the driving gear 1031, so that the driving gear 1031 drives the transmission gear 1021 to rotate, and then the pushing member 1022 of the transmission gear 1021 cooperates with the force-bearing member 1012 provided on the first bracket 1011, pushing the first bracket 1011 to drive the identification unit A to move from the initial position to the target position, so that the identification unit A contacts the electrical contact B of the main component. As shown Figure 1 and Figure 2 As shown, in order to further improve the reliability of the identification unit A contacting the electric contact B of the main component when the identification unit A is at the target position, the bracket module 101 is locked when the identification unit A is at the target position. This can prevent the identification unit A from accidentally separating from the electric contact B of the main component due to insufficient thrust of the first thrust mechanism 102.

[0155] like Figure 2 , Figure 4A to Figure 4C , Figure 5A and Figure 5B As shown, the first connecting member 1013 of the embodiment of the present application includes a first clamping portion K1, which is used to clamp with a second clamping portion K2 provided on the frame 104, so that the first bracket 1011 is locked when the identification unit A is located at the target position.

[0156] like Figure 4CAs shown, a third clamping portion K3 may be further provided on the frame 104 of the cartridge, and the first clamping portion K1 is further used to clamp with the third clamping portion K3 provided on the frame 104, so that the first bracket 1011 is locked when the recognition unit A is located at the initial position. When the recognition unit A moves from the initial position to the target position along the axis direction of the imaging member, the third clamping portion K3 and the second clamping portion K2 are distributed in the direction away from the frame 104 along the axis direction of the imaging member.

[0157] like Figure 2 , Figure 4A , Figure 4C , Figure 5A and Figure 5B As shown, considering that the force-bearing member 1012 is pushed by the pushing member 1022, driving the first bracket 1011 to move in a direction away from the transmission gear 1021, the first connecting member 1013 is driven by the force-bearing member 1012 to move away from the frame 104 along the axis direction of the imaging member, and the third clamping portion K3 and the second clamping portion K2 can be set to be on the same straight line, and the direction of the straight line can be the same as the axis direction of the imaging member. When the first connecting member 1013 is driven by the force-bearing member 1012 to move away from the frame 104 along the axis direction of the imaging member, the first clamping portion K1 can be separated from the third clamping portion K3 at the initial position, and when the identification unit A is located at the target position, the first clamping portion K1 is clamped with the second clamping portion K2 at the target position.

[0158] like Figure 2 , Figure 4A , Figure 4C , Figure 5A and Figure 5B As shown, when the frame 104 can be a solid structure, the first connecting member 1013 and the guide portion 1015 are both located outside the solid structure, and the second clamping portion K2 can be arranged on the outer side wall of the solid structure. When the frame 104 can be a hollow structure, the first connecting member 1013 and the guide portion 1015 can be located outside the hollow structure or inside the hollow structure. When the frame 104 is a hollow structure, the first connecting member 1013 is arranged on the inner side wall of the frame 104, and the driven protrusion Q is arranged on the outer side wall of the frame 104. At this time, the first connecting member 1013 and the driven protrusion Q are separated by the outer side wall of the frame 104.

[0159] like Figure 2 , Figure 4A , Figure 4C , Figure 5A and Figure 5BAs shown, the frame 104 may have a connecting shaft, which passes through the driving gear 1031 and enters into the sleeve structure of the pusher 1022. The first L-shaped hook and the second clamping portion K2 may be located on both sides of the transmission gear 1021, and the first L-shaped hook and the third clamping portion K3 may be located on both sides of the transmission gear 1021.

[0160] like Figure 2 , Figure 4A , Figure 4C , Figure 5A and Figure 5B As shown, when the connecting shaft is a solid structure, the second clamping portion K2 and the third clamping portion K3 can be arranged on the outer wall of the connecting shaft. At this time, the first clamping portion K1 and the guide portion 1015 are both located between the connecting shaft and the inner wall of the sleeve structure of the pusher 1022. In another example, when the connecting shaft is provided with a cavity having an opening, the opening is oriented in the direction of the first bracket 1011. At this time, the first clamping portion K1 and the guide portion 1015 can both penetrate into the cavity through the opening. At this time, the second clamping portion K2 and the third clamping portion K3 can be arranged on the inner wall of the cavity.

[0161] In one example, if Figure 2 , Figure 4A , Figure 4C , Figure 5A and Figure 5B As shown, when the first clamping portion K1 is a clamping hole, the clamping hole is used to clamp with a buckle provided on the frame 104, so that the first bracket 1011 is locked when the identification unit A is located at the target position. Here, the second clamping portion K2 and the third clamping portion K3 can both be implemented in the form of a buckle. In another example, the first clamping portion K1 is a buckle, which is used to clamp with a clamping hole provided on the frame 104, so that the first bracket 1011 is locked when the identification unit A is located at the target position. Here, the second clamping portion K2 and the third clamping portion K3 can both be implemented in the form of a clamping hole.

[0162] In order to facilitate understanding of the movement process of the recognition unit from the initial state to the target state in the embodiment of the present application, Fig. 7A A schematic diagram showing a three-dimensional structural state of a transmission mechanism of an identification unit in an embodiment of the present application in an initial position is shown. Figure 7B The schematic diagram of the cross-sectional structure state of the transmission mechanism of the identification unit in the embodiment of the present application in the initial position is shown. Fig. 7A and Figure 7B Give a description.

[0163] like Fig. 7A and Figure 7BAs shown, when the transmission gear 1021 is driven to rotate by the driving gear 1031, the transmission gear 1021 can drive the pusher 1022 to rotate, and the toggle tooth P provided on the pusher 1022 can contact the side of the driven protrusion Q provided on the force-bearing member 1012, and apply a force to the side of the driven protrusion Q. The side of the driven protrusion Q is inclined, and a component force can be generated in the axial direction of the imaging member, and point to the direction where the first bracket 1011 is located. In this way, the first clamping portion K1 gradually disengages from the third clamping portion K3, and moves in a direction close to the second clamping portion K2. Correspondingly, the force-bearing member 1012 provided with the driven protrusion Q can drive the identification unit A to move from the initial position in a direction away from the transmission gear 1021, that is, in a direction close to the target position, through the first bracket 1011.

[0164] Fig. 8A A schematic diagram showing a three-dimensional structural state of a transmission mechanism of an identification unit in an embodiment of the present application at a target position is shown. Figure 8B FIG. 2 is a schematic diagram showing a cross-sectional structural state of a transmission mechanism of an identification unit in an embodiment of the present application at a target position. Fig. 8A and Figure 8B As shown, when the first engaging portion K1 moves to the position of the second engaging portion K2, the first engaging portion K1 gradually engages with the second engaging portion K2, and the identification unit A moves from the initial position to the target position, so that the identification unit A contacts the electrical contact B of the main component.

[0165] It should be noted that Fig. 7A and Figure 7B , Fig. 8A and Figure 8B A connecting shaft is provided on the frame 104, and the connecting shaft passes through the transmission gear 1021. A cavity with an opening is provided at one end of the connecting shaft facing the first bracket 1011, and the connecting shaft has an opening cavity. The connecting shaft is provided with a third clamping portion K3 and a second clamping portion K2 away from the transmission gear 1021. Both the second clamping portion K2 and the third clamping portion K3 are clamping holes, and the first clamping portion K1 is a buckle. The first connecting member 1013 extends into the cavity through the opening, and the first clamping portion K1 provided on the first connecting member 1013 is clamped with the third clamping portion K3. The clamping hole is a through hole that passes through the side wall of the connecting shaft. Both the first connecting member 1013 and the guide portion 1015 can extend into the cavity through the opening.

[0166] like Figure 1 , Figure 2 , Fig. 7A and Figure 7B , Fig. 8A and Figure 8BAs shown, in order to improve the autonomous retraction capability of the first bracket 1011, the transmission mechanism may further include an elastic member S, one end of the elastic member S may be connected to the inside of the force-bearing member 1012, and the other end may be connected to the inside of the pushing member 1022, and the elastic member S may be sleeved on the connecting shaft. When the first bracket 1011 is subjected to a force directed in the direction of the transmission gear 1021, on the one hand, the first clamping portion K1 of the first connecting member 1013 may be separated from the second clamping portion K2, and under the rebound effect of the elastic member S, the first bracket 1011 provided with the force-bearing member 1012 is quickly pulled to drive the identification unit A to return from the target position to the initial position.

[0167] In some alternatives, Fig.9A A schematic diagram of a connection structure between a driving gear and a driving shaft in an embodiment of the present application is shown. Fig. 9B An exploded schematic diagram of the connection between the drive gear and the drive shaft of an embodiment of the present application is shown. Fig.9A and Fig. 9B As shown, the driving gear 1031 of the embodiment of the present application can be a one-way rotating bearing structure. The driving shaft 105 can be connected to the driving gear 1031 through a one-way bearing 1033. For example, the one-way bearing 1033 can be sleeved on the driving shaft 105, and the driving gear 1031 can be arranged on the one-way bearing.

[0168] like Fig.9A and Fig. 9B As shown, when the driving gear 1031 is arranged on the driving shaft 105, if the driving shaft 105 is compatible with other functions, such as the toner cartridge shaft function, the driving shaft 105 and the driving gear 1031 can be decoupled under certain conditions through the one-way rotating bearing structure.

[0169] like Fig.9A and Fig. 9B As shown, taking the image forming device in which the drive shaft 105 is compatible with the function of the drum shaft as an example, when the cartridge is installed in the image forming device, the drive shaft 105 can drive the one-way bearing 1033 to rotate along the first rotation direction, thereby driving the drive gear 1031 to rotate along the first rotation direction with the drive shaft 105. When the drive gear 1031 rotates, the drive gear 1031 drives the transmission gear 1021 to rotate, so as to use the pusher 1022 provided on the transmission gear 1021 to push the bracket module 101, so that the bracket module 101 drives the identification unit A to move from the initial position to the target position. When the image forming device recognizes the identification unit A, the drive shaft 105 rotates along the second rotation direction to perform the printing operation.

[0170] The first rotation direction and the second rotation direction are two opposite rotation directions. For example, when the first rotation direction is a forward rotation direction of the imaging member, the second rotation direction is a reverse rotation direction of the imaging member.

[0171] Exemplarily, the positive rotation direction of the imaging member can be a clockwise rotation direction or a counterclockwise rotation direction. For example, when the first rotation direction is a clockwise rotation direction, the second rotation direction is a counterclockwise rotation direction. For another example, when the first rotation direction is a counterclockwise rotation direction, the second rotation direction is a clockwise rotation direction.

[0172] like Fig.9A and Fig. 9B As shown, when the image forming device performs a printing operation, the drive shaft 105 is compatible with the toner drum shaft function, so the drive shaft 105 will rotate along the second rotation direction. Since the one-way bearing 1033 is sleeved on the drive shaft 105 and the drive gear 1031 is fixed on the one-way bearing 1033, the one-way bearing 1033 and the drive gear 1031 fixed on the one-way bearing 1033 will not rotate as the drive shaft 105 rotates along the second rotation direction. This can not only ensure the normal operation of the image forming device, but also reduce the risk of tooth collision between the drive gear 1031 and the transmission gear 1021, thereby avoiding the noise generated by tooth collision between the drive gear 1031 and the transmission gear 1021, which affects the user experience. On the other hand, if tooth collision occurs between the drive gear 1031 and the transmission gear 1021, one of the drive gear 1031 and the transmission gear 1021 or both of them will be damaged, affecting the service life of the box.

[0173] In some alternatives, Fig. 10A A schematic diagram showing the structural state of the identification unit in the embodiment of the present application in the initial position when the transmission gear is missing teeth is shown. Fig. 10B The schematic diagram of the structure state of the recognition unit in the embodiment of the present application at the target position when the transmission gear is missing teeth is shown. Fig. 10A and Fig. 10B As shown, the transmission gear 1021 of the embodiment of the present application includes a toothless portion 1021A and a toothed portion 1021B, and the circumferential length of the toothed portion 1021B is greater than the circumferential length of the toothless portion 1021A.

[0174] like Fig. 10A and Fig. 10BAs shown, when the identification unit A is in the initial position, the driving gear 1031 meshes with the toothed portion 1021B of the transmission gear 1021. Taking the printer as an example, after the cartridge is placed in the toner cartridge drawer of the printer, the printer can detect that the front cover is closed, and can control the driving shaft 105 to drive the driving gear 1031 to reverse, and the driving gear 1031 drives the transmission gear 1021 to rotate, so as to push the bracket module 101 through the pusher 1022 provided on the transmission gear 1021, so that the bracket module 101 drives the identification unit A to move from the initial position to the target position, so that the identification unit A can contact the electrical contact B of the main component. At this time, the driving gear 1031 contacts the toothless portion 1021A of the transmission gear 1021.

[0175] like Fig. 10A and Fig. 10B As shown, when the printer performs a printing operation, although the driving gear 1031 rotates, since the identification unit A can contact the electrical contact B of the main component, the driving gear 1031 contacts the toothless portion 1021A of the transmission gear 1021. Therefore, although the driving gear 1031 is still rotating with the driving shaft 105 (such as the driving shaft 105 drives the driving gear 1031 to rotate forward), the transmission gear 1021 no longer rotates, which can effectively prevent the problem of tooth collision between the driving gear 1031 and the transmission gear 1021. After the printer performs a printing operation, the identification unit A can be returned to the initial state, at which time the driving gear 1031 is meshed with the toothed portion 1021B of the transmission gear 1021.

[0176] The present application also provides an image forming device, which can reduce the risk of wear and scratch of the recognition unit through the box provided therein, thereby ensuring the life of the chip. Here, the image forming device can be a printer, a copier, etc., but is not limited thereto.

[0177] Fig.11 FIG. 2 shows a schematic diagram of an exploded structure of an image forming device according to an embodiment of the present application. Fig.11 As shown, the image forming device disclosed in the embodiment of the present application may include an electrical contact B of a main component and a cartridge 100, and the cartridge 100 is detachably mounted on the image forming device. The identification unit A included in the cartridge is electrically connected to the electrical contact B of the main component at a target position. It should be understood that Fig.11 Only some structures are identified. Although the unidentified structures are described in detail in the embodiments of the present application, they can be determined by referring to the relevant technology.

[0178] In practical applications, the electrical contact B of the main component may refer to the main body contact of the image forming device, the cartridge may refer to a photosensitive device such as a toner cartridge, and the identification unit A may refer to a device that can contact the electrical contact B of the main component to achieve data communication. Taking a printer as an example, the cartridge may be pushed into the cartridge installation portion in the printer, and then the identification unit A in the cartridge is electrically connected to the electrical contact B of the main component at the target position, thereby completing the detachable installation of the cartridge.

[0179] like Fig.11 As shown, the image forming apparatus of the embodiment of the present application may further include a second bracket 201. For example, the second bracket 201 may be a track of a drawer for placing the box, and the box is installed in the image forming apparatus by pulling the drawer open, placing the box in the drawer, and then pushing the box into the drawer using the second bracket 201 as a track.

[0180] In some alternatives, such as Fig.11 As shown, the side of the first bracket 1011 included in the cartridge 100 of the embodiment of the present application has a reset structure 1016, and the image forming device may further include a second thrust mechanism 202 provided on the second bracket 201, and the second thrust mechanism 202 matches the reset structure 1016. When the identification unit A contacts the electrical contact B of the main component, the second thrust mechanism 202 acts on the reset structure 1016 of the cartridge and applies a force to separate the identification unit A from the electrical contact B of the main component.

[0181] In order to more clearly understand the process of installing and removing the cartridge in the image forming device according to the embodiment of the present application, Fig. 12A A schematic diagram showing the process of installing and removing a cartridge in a printer is shown, Fig. 12B A schematic diagram showing the positional relationship between the reset structure and the first thrust mechanism 102 during the printing operation is shown. Fig. 12C The positional relationship between the reset structure and the first thrust mechanism 102 after printing is completed is shown. The following figures describe the cartridge installation and removal process of the embodiment of the present application. Figures 12A to 12C As shown, the method for installing and removing a cartridge in a printer according to an embodiment of the present application may include the following steps:

[0182] Step 1201: When the cartridge is installed in the printer, there is a gap between the identification unit and the electrical contact B of the main component of the printer. For example, when the cartridge 100 includes the end cover 106, the identification unit A provided by the bracket module 101 is retracted on the side of the end cover 106 close to the first thrust mechanism 102. It can also be understood that the end cover 106 includes an inner side and an outer side, the inner side is close to the first thrust mechanism 102, and there is a gap between the identification unit A and the electrical contact B of the main component of the printer, that is, the identification unit A is located on the inner side of the end cover 106.

[0183] Step 1202: The printer sends a print instruction to the motor driver of the drive shaft.

[0184] Step 1203: The motor driver controls the motor to drive the drive shaft to rotate in response to the print instruction. The drive shaft 105 here can be a rotating shaft independent of the drum shaft, or a drum shaft (also called OPC shaft) compatible with the function of the drive shaft.

[0185] Step 1204: During the rotation of the driving shaft, the driving shaft drives the driving gear to rotate, and the driving gear drives the transmission gear to rotate.

[0186] Step 1205: The transmission gear drives the pusher to push the first bracket, so that the first bracket drives the identification unit to move from the initial position to the target position.

[0187] like Fig.11 , Figures 12A to 12C As shown, when the box 100 includes the end cover 106, the process of the identification unit A moving from the initial position to the target position is actually extending from the side of the end cover 106 close to the first thrust mechanism 102 to the side of the end cover 106 away from the first thrust mechanism 102. When the identification unit A is at the target position, the pushing end of the second thrust mechanism 202 provided on the second bracket 201 is opposite to the reset structure 1016 provided on the side of the first bracket 1011.

[0188] Step 1206: When the recognition unit is at the target position, the recognition unit contacts the electrical contacts of the main component, so that the printer recognizes the recognition unit and performs a printing operation.

[0189] like Fig.11 , Figures 12A to 12C As shown, when the identification unit A contacts the electrical contact B of the main component, the identification unit A can communicate with the electrical contact B of the main component, and the printer can then perform printing operations normally. If the printer's toner drum shaft is compatible with the function of the drive shaft, during the process of the identification unit A moving from the initial position to the target position, if the toner drum shaft rotates clockwise, then after the printer successfully identifies the identification unit A, the toner drum shaft rotates counterclockwise to perform the printing operation; conversely, during the process of the identification unit A moving from the initial position to the target position, if the toner drum rotates counterclockwise, then after the printer successfully identifies the identification unit A, the toner drum shaft rotates clockwise to perform the printing operation.

[0190] like Fig.11 , Figures 12A to 12C As shown, the toothing solution between the driving gear 1031 and the transmission gear 1021 can refer to the above Fig.9A and Fig. 9B The disclosed technical solution can also be referred to Fig. 10A and Fig. 10B Another technical solution disclosed in the present invention is shown.

[0191] like Fig.11 , Figures 12A to 12C As shown, after the printing operation is completed, the identification unit A and the electrical contact B of the main component can remain in contact, or can be separated manually or by other control methods. For example, while the identification unit A and the electrical contact B of the main component are kept in contact, the next printing operation can be waited for. When the next printing operation starts, it will return to step 1202 and re-execute steps 1202 to 1206.

[0192] For example, Fig.11 , Figures 12A to 12C As shown, when a reset structure is provided on the first bracket 1011, the identification unit A can be separated from the electrical contact B of the main component manually or by the printer control after the printing operation. Taking the manual separation of the identification unit A from the electrical contact B of the main component as an example, the following steps may also be included:

[0193] Step 1207: Open the door of the printer installation box and pull the drawer of the installation box to retract the installed identification unit into the end cover.

[0194] like Fig.11 , Figures 12A to 12C As shown, when the door of the printer installation box 100 is opened, the drawer in which the box 100 is placed is pulled, so that the drawer drives the box 100 to gradually approach the second thrust mechanism 202 under the guidance of the second bracket 201, until the reset structure 1016 set on the side of the first bracket 1011 in the box 100 collides with the second thrust mechanism 202, so that the first bracket 1011 drives the identification unit A to retreat into the end cover 106.

[0195] like Fig.11 , Figures 12A to 12C As shown, when the first bracket 1011 drives the identification unit A to retract into the end cover 106, the identification unit A is separated from the electrical contact B of the main assembly. If the box 100 needs to be replaced or removed, step 1207 can be performed.

[0196] Step 1208: After the drawer is pulled out, take out the box in the drawer or replace it with a new one. Fig.11 , Figures 12A to 12C As shown, if a new cartridge 100 is replaced, the process may return to step 1201. Here, during the printing operation of the printer, the identification unit A contacts the electrical contact B of the main assembly.

[0197] like Fig.11 , Figures 12A to 12C As shown, after the printing operation is completed, you can follow Fig. 12B The drawer is manually pulled in the direction of the arrow shown, so that the drawer moves along the second bracket 201 to Fig. 12AThe first bracket 1011 moves in the direction of the arrow shown, so that the reset surface on the first bracket 1011 gradually approaches the push end of the second thrust mechanism 202 provided on the second bracket 201, and finally collides with the push end of the second thrust mechanism 202 provided on the second bracket 201. At this time, since the reset surface on the first bracket 1011 is an inclined surface, under a large reaction force, it will generate a component force pointing to the direction of the transmission gear 1021 in the axial direction of the imaging member, so that the first bracket 1011 drives the identification unit A to separate from the electrical contact B of the main component and retreat to a certain extent, while the box continues to move along the axis of the imaging member driven by the drawer. Fig. 12B Move in the direction of the arrow until Fig. 12C Status shown.

[0198] For example, Fig.11 , Fig. 12B and Fig. 12C As shown, when the second thrust mechanism 202 is a blocking block provided on the second bracket 201. After the printing operation is completed, the front door of the printer can be opened and the powder box drawer can be pulled so that the powder box drawer drives the first bracket 1011 to gradually contact the blocking block, and then the blocking block can exert a force on the reset surface on the first bracket 1011, thereby separating the identification unit A from the electrical contact B of the main component.

[0199] It should be noted that if Fig.11 , Figures 12A to 12C As shown, the first bracket 1011 drives the identification unit A to separate from the electrical contact B of the main component and retracts to a certain extent. In addition to being completed manually, the retraction operation can also be integrated into the control logic of the printer, and the printer can be used to control other possible pushing mechanisms to apply force to the reset surface to separate the identification unit A from the electrical contact B of the main component.

[0200] For example, Fig.11 , Figures 12A to 12C As shown, the second thrust mechanism 202 may be a trigger controlled by the printer, for example, the trigger may be a reciprocating mechanism, such as a piston, a cam, etc. When the second thrust mechanism 202 is a trigger, after the printer detects that the printing operation is completed, it may actively send a retraction instruction to the trigger, so that the trigger applies a force on the reset surface on the first bracket 1011, thereby separating the identification unit A from the electrical contact B of the main assembly.

[0201] Another implementation method may be as follows Fig.11 , Figure 12A to Figure 12BAs shown, taking the printer as an example, the cartridge 100 is installed in the printer, the printer is powered on, and the reset mechanism of the identification unit A inside the printer (i.e., the mechanism that realizes the function of the second thrust mechanism) is started, pushing the identification unit A to reset. At this time, the consumables module on the printer first determines whether the identification unit A is in contact with the electrical contact B of the main component through the IIC communication protocol. If so, the printer reports an error. If not, the printer notifies the driving gear in the driving module 103 inside the printer to drive the transmission gear 1021 to rotate. The transmission gear 1021 rotates and pushes the bracket module 101 to move, so that the identification unit A moves from the initial position to the target position, so that the identification unit A is in contact with the electrical contact B of the main component. The consumables module on the printer secondly determines whether the identification unit A is in contact with the electrical contact B of the main component through the IIC communication protocol. If the identification unit A is in contact with the electrical contact B of the main component, the printer is ready and the printer can print normally. If the identification unit A is not in contact with the electrical contact B of the main component, the printer reports an error. The printer can also report the error information to the data display module (such as the display panel of the printer), and the display module displays the printer error information when the identification unit A is not in contact with the electrical contact B of the main component. The identification unit A can maintain contact with the electrical contact B of the main component, or the second thrust mechanism 202 acts on the reset structure 1016 of the box and applies a force to separate the identification unit A from the electrical contact B of the main component.

[0202] During shutdown of the image forming apparatus, Fig.11 , Figures 12A to 12C As shown, if the identification unit A contacts the electrical contact B of the main component, the second thrust mechanism 202 can cooperate with the reset structure 1016, and with reference to the above description, the identification unit A can be separated from the electrical contact B of the main component, so that the identification unit A returns to the initial position. When the image forming device is turned on, the image forming device will restart the transmission mechanism in the box 100 to make the identification unit A contact the electrical contact B of the main component again, so that the identification unit A can communicate with the electrical contact B of the main component, and the image forming device will detect the identification unit A through the electrical contact B of the main component to determine whether the box 100 is installed in place, and can further determine whether the box 100 is the original box of the image forming device.

[0203] Taking a printer as an example, the following describes the process of detecting the box installation status of the printer during the printer startup process. Fig.13 The figure shows a flow chart of the installation status of the printer detection box in the embodiment of the present application. Fig.13 As shown, the method for the printer to detect the installation status of the box in the embodiment of the present application includes the following steps:

[0204] Step 1301: Turn on the printer. Before turning on the printer, the printer box can be installed in the printer, such as Fig. 7A and Figure 7B As shown, the identification unit A is in a separated state from the electrical contact B of the main component, and the identification unit A is in an initial position.

[0205] Step 1302: The identification unit installed on the printer control box is reset / or the identification unit is in a reset state when the box is installed on the printer. Fig.11 , Figures 12A to 12C As shown, the resetting of the identification unit A here can be understood as the process of the identification unit A retreating from the target position to the initial position. For example, after the printer completes a printing operation, the identification unit A of the cartridge 100 is reset by the printer control operation, so that the identification unit A is separated from the electrical contact B of the main component. Or the position of the identification unit A is at the initial position, which can be understood as when the cartridge 100 is installed in the printer, there is a gap between the identification unit A and the electrical contact B of the main component, that is, the identification unit A and the electrical contact B of the main component are separated.

[0206] Step 1303: The printer detects for the first time whether the electrical contact B of the main component is in contact with the identification unit A through the IIC communication protocol.

[0207] like Fig.11 , Figures 12A to 12C As shown, after executing step 1302, there will be no contact between the electrical contact B of the main component and the identification unit A. Therefore, if the printer detects that the electrical contact B of the main component is in contact with the identification unit A for the first time within a non-preset time period, it means that the identification unit A is abnormal. At this time, it means that the box 100 is not installed in place in the printer, or the box 100 is not an original box of the image forming device. Step 1304 can be executed. When the printer detects for the first time that the electrical contact B of the main component is not in contact with the identification unit A (i.e., separated), it means that the identification unit is normal and the identification unit is in the initial position. Step 1305 can be executed.

[0208] Step 1304: The printer determines that the identification unit does not match the printer. When the identification unit A does not match the printer, the printer may generate an error status and report the error on the printer's operation panel. For example, Fig.11 As shown, the error status can be displayed through the panel display area on the printer, which means that the box 100 is not installed properly in the printer, or the box 100 is not an original box of the image forming device.

[0209] Step 1305: The printer controls the driving motor of the driving shaft to reverse, so as to control the driving shaft to drive the transmission mechanism to push the identification unit.

[0210] like Fig.11 , Figures 12A to 12CAs shown, the drive shaft 105 can rotate clockwise or counterclockwise. When the transmission mechanism in the box 100 pushes the identification unit A, the identification unit A can be pushed from the initial position to the target position within a preset time, so that the identification unit contacts the electrical contacts of the main component.

[0211] Step 1306: The printer detects whether the electrical contact B of the main component is in contact with the identification unit A for the second time, that is, within a preset time period, through the IIC communication protocol.

[0212] like Fig.11 , Figures 12A to 12C As shown, if the printer does not receive the contact information between the electrical contact B of the main component and the identification unit A detected for the first time, it means that the printer can control the transmission mechanism to push the identification unit A to contact the electrical contact B of the main component within the preset time, and steps 1305 and 1306 can be executed.

[0213] like Fig.11 As shown, if the printer receives the first detection that the electrical contact B of the main component is in contact with the identification unit A, it means that the identification unit A does not match the printer.

[0214] Step 1307: The printer is ready. After the printer is ready, if a printer operation needs to be performed, step 1308 can be performed.

[0215] Step 1308: The printer performs a printing operation. After the printing operation is completed, Fig.11 , Figures 12A to 12C As shown, if the user needs to replace the cartridge 100, the front door of the printer (i.e., the openable and closable door of the printer where the cartridge 100 is installed) can be opened.

[0216] Step 1309: Manually pull out the drawer of the installation box to reset the identification unit. Fig.11 , Figures 12A to 12C As shown, after the identification unit A retreats, the front door of the printer is closed, and the process returns to step 1303. When the printer is not in use, step 1310 may be selectively performed.

[0217] Step 1310: The printer is turned off. If the user turns the printer on again, the process returns to step 1301.

[0218] It should be noted that if Fig.11 , Figures 12A to 12C As shown, the box of the embodiment of the present application may also include an end cover 106. When the identification unit A is located at the initial position, the bracket module 101, the first thrust mechanism 102, the drive module 103 and the identification unit A are arranged inside the end cover 106; when the identification unit A is located at the target position, the identification unit A is located outside the end cover 106.
