Description

Technical Field

[0001] The utility model relates to the technical field of image forming equipment, in particular to an adapter and a processing box. Background Art

[0002] Image forming devices such as laser printers, copiers, and multifunction printers all have a process cartridge (also called a toner cartridge) inside them. The process cartridge is an important component in image forming devices and contains consumable chips.

[0003] The existing processing box includes a powder bin, a waste powder bin, a drive end cover, a conductive end cover, a bracket, and a chip. The conductive end cover is provided with a bracket, and the chip is installed on the bracket. When the processing box is placed on the drawer and the drawer is pushed into the printer at the same time, the chip on the processing box will contact the main body spring. When pushed to the installation position, the conductive contacts on the chip can conduct electricity through the main body spring.

[0004] In the above description, the main body spring is fixed on the frame of the image forming device, and has no telescopic structure. It can be elastically deformed through the interference fit with the processing box chip to achieve contact and conduction between the two. When the drawer is pushed into the machine body, the electrical contacts of the chips on the four processing boxes K, M, C, and Y (representing four colors) will contact the main body spring. As the processing box is pushed in, the contacts of the main body spring and the electrical contacts of the box chip undergo a long displacement of dry friction until the processing box is pushed into place, the dry friction ends, and the contacts of the main body spring and the electrical contacts of the processing box chip are in static contact. During the repeated pushing and pulling of the drawer, the contacts of the main body spring will cause significant wear on the electrical contacts on the surface of the processing box chip. This results in unstable conductive contact of the processing box chip, making it impossible for the printer to correctly identify the processing box chip, affecting the normal use of the printer, and thus reducing the printer quality and user experience.

[0060] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0061] On the one hand, in order to solve the technical problem that the friction between the main body contact 60 of the image forming device and the electrical contact 21 of the processing box chip causes great wear on the electrical contact 21, an embodiment of the present utility model provides an adapter for being installed on the processing box, and the processing box can be detachably installed on the image forming device. The image forming device has a main body contact 60, and the adapter includes a driven part 20. The driven part 20 is provided with an electrical contact 21 for electrically connecting to the main body contact 60. When the processing box is installed on the image forming device, the driven part 20 can move relative to the box body of the processing box under the action of external force. The driven part 20 has a first position and a second position during the movement. When the driven part 20 is in the first position, the electrical contact 21 is not electrically connected to the main body contact 60; when the driven part 20 moves to the second position, the electrical contact 21 is electrically connected to the main body contact 60.

[0062] Furthermore, the adapter also includes a power transmission member 10. When the processing box is installed in the image forming device, the power transmission member 10 can move under the action of external force, and the power transmission member 10 resists the driven member 20 during the movement, pushing the driven member 20 to move from the first position to the second position.

[0063] In the embodiment provided by the present utility model, a forced pushing portion 11 is provided on the power transmission member 10, a forced pushing portion 22 is provided on the driven member 20, and a forced pushing inclined surface is provided on the forced pushing portion 11 and / or the forced pushing portion 22. Figure 6 as well as Figure 7 As shown, the forced pushing portion 11 has a first forced pushing inclined surface 111, and the forced pushing portion 22 has a second forced pushing inclined surface 221. The inclination direction and angle of the first forced pushing inclined surface 111 and the second forced pushing inclined surface 221 are consistent. When the power transmission member 10 moves downward, the first forced pushing inclined surface 111 abuts against the second forced pushing inclined surface 221, and the force acting on the second forced pushing inclined surface 221 can be decomposed into a component force in the second direction D2. The component force pushes the driven member 20 to move from the first position to the second position, thereby realizing the electrical connection between the electrical contact 21 and the body contact 60.

[0064] Reference Figures 1 to 5As shown, the adapter provided in the embodiment of the present invention further includes a first elastic member 40. The first elastic member 40 is connected between the power transmission member 10 and a first predetermined portion of the cartridge body to allow the power transmission member 10 to elastically return to its original position when the external force disappears. As the power transmission member 10 is moved by the driving member 30, the first elastic member 40 accumulates elastic force. When the cartridge is to be withdrawn from the image forming apparatus, the downward pressure of the driving member 30 on the power transmission member 10 is released, and this elastic force acts on the power transmission member 10, causing it to move in the opposite direction and return to its original position.

[0065] In other embodiments, the first elastic member 40 may be other structures or components that can accumulate elastic force and act on the power transmission member 10 , which is not limited here.

[0066] In the embodiment provided by the present invention, the processing box also includes a bracket body 50, and the first preset part of the box body of the processing box is this bracket body 50. In a feasible implementation manner, the first elastic member 40 is a tension spring, one end of the tension spring is connected to the power transmission member 10, and the other end of the tension spring is connected to the bracket body 50. The tension spring accumulates elastic force during the downward movement of the power transmission member 10. After the driving member 30 releases the external force on the power transmission member 10, the elastic force acts on the power transmission member 10 to return the power transmission member 10 to its original position.

[0067] In other embodiments, the first elastic member 40 may be other structures or components that can accumulate elastic force and act on the power transmission member 10 , which is not limited here.

[0068] The processing box also includes a second elastic member, which is connected between the driven member 20 and a second preset position of the box body of the processing box, so that the driven member 20 can return to the first position from the second position when the external force disappears, so that the electrical contact 21 is away from the main body contact 60, thereby avoiding unnecessary friction between the electrical contact 21 and the main body contact 60 during the extraction of the processing box.

[0069] During the process of the driven part 20 moving under the action of the power transmission part 10, the second elastic part accumulates elastic force. When the power transmission part 10 moves back to its original position, the driven part 20 is no longer affected by the force of the power transmission part 10. The elastic force of the second elastic part acts on the driven part 20, so that the driven part 20 moves in the opposite direction and returns to the first position.

[0070] In a feasible embodiment, the second preset part of the box body of the processing box is the bracket body 50, and the second elastic member is a compression spring. One end of the compression spring is connected to the driven member 20, and the other end of the compression spring is connected to the bracket body 50. The compression spring is compressed during the process of the driven member 20 moving from the first position to the second position, thereby accumulating elastic force. After the power transmission member 10 releases the external force on the driven member 20, the compression spring stretches and releases the elastic force. The elastic force acts on the driven member 20, so that the driven member 20 moves in the opposite direction and the driven member 20 returns to the first position.

[0071] In other embodiments, the second elastic member may be other structures or components that can accumulate elastic force and act on the driven member 20, which is not limited here.

[0072] Reference Figure 1 、 Figure 2 、 Figure 3 as well as Figure 5 As shown, a first guide portion 51 and a second guide portion 52 are provided on the bracket body 50. The first guide portion 51 extends along the first direction D1, and the power transmission member 10 forms a guiding fit with the first guide portion 51. Under the action of the first guide portion 51, the power transmission member 10 can only move back and forth along the first direction D1 to prevent the power transmission member 10 from being offset when moving in the first direction D1, avoiding the deflection of the external force acting on the driven member 20, resulting in affecting the movement of the driven member 20.

[0073] The second guide portion 52 extends along the second direction D2, and the driven member 20 forms a guiding fit with the second guide portion 52. Under the action of the second guide portion 52, the driven member 20 can only move back and forth along the second direction D2, thereby avoiding the displacement of the driven member 20 during movement, so that good electrical contact effect can be maintained between the electrical contact 21 on the driven member 20 and the main body contact 60.

[0074] The second direction D2 is the moving direction of the driven component 20 approaching the body contact 60 , and the second direction D2 is orthogonal to the first direction D1 .

[0075] In the embodiment provided by the present invention, the process cartridge includes a chip board 23, with electrical contacts 21 disposed on the chip board 23. A first chip mounting portion 24 is provided on the driven member 20, with the chip board 23 disposed on the first chip mounting portion 24. The chip board 23 extends perpendicularly to the second direction D2. The first chip mounting portion 24 is disposed at the end of the driven member 20 that faces the inner sidewall of the image forming device. Because the chip board 23 extends perpendicularly or nearly perpendicularly, the electrical contacts 21 maintain a large contact surface with the body contacts 60, and the springs on which the body contacts 60 are mounted are less likely to slip off the electrical contacts 21.

[0076] In another feasible embodiment, the electrical contacts 21 on the driven part 20 can also be adapters between the processing box chip and the printer body contacts 60. Specifically, the processing box includes a chip board, and the electrical contacts are also used to electrically connect to the contacts of the chip board.

[0077] Furthermore, the image forming apparatus further includes a movable driving member 30. When the adapter is mounted on the process cartridge, and the process cartridge is mounted on the image forming apparatus, the driving member 30 can abut against the power transmission member 10 during movement, causing the power transmission member 10 to move. After the driving member 30 rotates until it abuts against the power transmission member 10, it continues to apply force to the power transmission member 10 as it moves, causing the power transmission member 10 to move downward, thereby driving the driven member 20 to move. As the driving member 30 continues to rotate, the power transmission member 10 continues to move downward. When the driven member 20 moves to the point where the electrical contact 21 contacts the body contact 60 and cannot move further, the driven member 20 reaches the second position, establishing an electrical connection between the electrical contact 21 and the body contact 60.

[0078] In a second aspect, the present invention provides a process cartridge that can be detachably mounted in an image forming device, wherein the image forming device has a body contact 60 and a driving member 30, and the process cartridge includes a cartridge body, a power transmission member 10 and a driven member 20 provided on the cartridge body, wherein:

[0079] The power transmission component 10 can move along the first direction D1 under the action of external force. In the embodiment provided by the present invention, the first direction D1 is preferably the direction of gravity or has a certain angle with the direction of gravity. The power transmission component 10 is arranged above the driven component 20 in the direction of gravity.

[0080] The driven member 20 is arranged at the end of the box body, and the electrical contact 21 is arranged on the driven member 20. When the processing box is installed in the image forming device, the driven member 20 can move relative to the box body under the action of external force. The driven member 20 has a first position and a second position during the movement. When the driven member 20 is in the first position, the electrical contact 21 is not electrically connected to the main body contact 60; when the driven member 20 moves to the second position, the electrical contact 21 is electrically connected to the main body contact 60.

[0081] Preferably, the driven member 20 moves along a second direction D2, which is orthogonal to the first direction D1. The second direction D2 is the moving direction of the driven member 20 approaching the main body contact 60. During the process of installing the processing box to the image forming device and after it is installed in place, the driven member 20 is in the first position, the electrical contact 21 is not electrically connected to the main body contact 60, and there is a certain distance between the electrical contact 21 and the main body contact 60. This distance is not enough to form non-contact power supply between the electrical contact 21 and the main body contact 60. During the process of pushing the processing box in or out, no contact is generated between the electrical contact 21 and the main body contact 60, thereby avoiding friction between the electrical contact 21 and the main body contact 60, thereby preventing wear on the electrical contact 21 caused by friction.

[0082] After the processing box is installed in the image forming device, the driving member 30 rotates to abut against the power transmission member 10. During the continued movement, the driving member 30 continues to apply force to the power transmission member 10, causing the power transmission member 10 to move downward, thereby driving the driven member 20 to move. As the driving member 30 continues to rotate, the power transmission member 10 continues to move downward. When the driven member 20 moves to the point where the electrical contact 21 contacts the main body contact 60 and cannot move further, the driven member 20 reaches the second position, and an electrical connection is formed between the electrical contact 21 and the main body contact 60.

[0083] In the embodiment provided by the present utility model, a forced pushing portion 11 is provided on the power transmission member 10, a forced pushing portion 22 is provided on the driven member 20, and a forced pushing inclined surface is provided on the forced pushing portion 11 and / or the forced pushing portion 22. Figure 6 as well as Figure 7 As shown, the forced pushing portion 11 has a first forced pushing inclined surface 111, and the forced pushing portion 22 has a second forced pushing inclined surface 221. The inclination direction and angle of the first forced pushing inclined surface 111 and the second forced pushing inclined surface 221 are consistent. When the power transmission member 10 moves downward, the first forced pushing inclined surface 111 abuts against the second forced pushing inclined surface 221, and the force acting on the second forced pushing inclined surface 221 can be decomposed into a component force in the second direction D2. The component force pushes the driven member 20 to move from the first position to the second position, thereby realizing the electrical connection between the electrical contact 21 and the body contact 60.

[0084] Reference Figures 1 to 5 As shown, the process cartridge provided in an embodiment of the present invention further includes a first elastic member 40, which is connected between the power transmission member 10 and a first predetermined portion of the cartridge body to allow the power transmission member 10 to elastically return to its original position when the external force disappears. As the power transmission member 10 is moved by the driving member 30, the first elastic member 40 accumulates elastic force. When the process cartridge needs to be withdrawn from the image forming apparatus, the downward pressure of the driving member 30 on the power transmission member 10 is released, and this elastic force acts on the power transmission member 10, causing it to move in the opposite direction and return to its original position.

[0085] In other embodiments, the first elastic member 40 may be other structures or components that can accumulate elastic force and act on the power transmission member 10 , which is not limited here.

[0086] In the embodiment provided by the present invention, the processing box also includes a bracket body 50, and the first preset part of the box body is this bracket body 50. In a feasible implementation manner, the first elastic member 40 is a tension spring, one end of the tension spring is connected to the power transmission member 10, and the other end of the tension spring is connected to the bracket body 50. The tension spring accumulates elastic force during the downward movement of the power transmission member 10. After the driving member 30 releases the external force on the power transmission member 10, the elastic force acts on the power transmission member 10 to return the power transmission member 10 to its original position.

[0087] In other embodiments, the first elastic member 40 may be other structures or components that can accumulate elastic force and act on the power transmission member 10 , which is not limited here.

[0088] The processing box also includes a second elastic member, which is connected between the driven member 20 and a second preset position of the box body, so that the driven member 20 can return to the first position from the second position when the external force disappears, so that the electrical contact 21 is away from the main body contact 60, thereby avoiding unnecessary friction between the electrical contact 21 and the main body contact 60 during the extraction of the processing box.

[0089] During the process of the driven part 20 moving under the action of the power transmission part 10, the second elastic part accumulates elastic force. When the power transmission part 10 moves back to its original position, the driven part 20 is no longer affected by the force of the power transmission part 10. The elastic force of the second elastic part acts on the driven part 20, so that the driven part 20 moves in the opposite direction and returns to the first position.

[0090] In a feasible embodiment, the second preset component is a bracket body 50, and the second elastic member is a compression spring. One end of the compression spring is connected to the driven member 20, and the other end of the compression spring is connected to the bracket body 50. The compression spring is compressed during the process of the driven member 20 moving from the first position to the second position, thereby accumulating elastic force. After the power transmission member 10 releases the external force on the driven member 20, the compression spring stretches and releases the elastic force. The elastic force acts on the driven member 20, so that the driven member 20 moves in the opposite direction and the driven member 20 returns to the first position.

[0091] In other embodiments, the second elastic member may be other structures or components that can accumulate elastic force and act on the driven member 20, which is not limited here.

[0092] Reference Figure 1 、 Figure 2 、 Figure 3 as well as Figure 5 As shown, a first guide portion 51 and a second guide portion 52 are provided on the bracket body 50. The first guide portion 51 extends along the first direction D1, and the power transmission member 10 forms a guiding fit with the first guide portion 51. Under the action of the first guide portion 51, the power transmission member 10 can only move back and forth along the first direction D1 to prevent the power transmission member 10 from being offset when moving in the first direction D1, avoiding the deflection of the external force acting on the driven member 20, resulting in affecting the movement of the driven member 20.

[0093] The second guide portion 52 extends along the second direction D2, and the driven member 20 forms a guiding fit with the second guide portion 52. Under the action of the second guide portion 52, the driven member 20 can only move back and forth along the second direction D2, thereby avoiding the displacement of the driven member 20 during movement, so that good electrical contact effect can be maintained between the electrical contact 21 on the driven member 20 and the main body contact 60.

[0094] Reference Figure 6 as well as Figure 8 As shown, in a feasible embodiment, an abutting portion 31 is provided on the driving member 30, and an arc-shaped abutting surface 311 is formed on the abutting portion 31. An abutted portion 12 is provided at one end of the power transmission member 10 close to the driving member 30, and the abutted portion 12 is used to abut with the arc-shaped abutting surface 311. When the driving member 30 moves, the arc-shaped abutting surface 311 abuts against the abutted portion 12. As the driving member 30 continues to move, based on the shape characteristics of the arc-shaped abutting surface 311, the arc-shaped abutting surface 311 and the abutted portion 12 always maintain an abutting state, and the abutted portion 12 can be continuously subjected to a downward force, thereby enabling the power transmission member 10 to continue to move along the first direction D1. Since the forced pushing portion 11 of the power transmission member 10 abuts against the forced pushing portion 22 of the driven member 20, the driven member 20 is pushed to move along the second direction D2. A connecting column 13 is further provided at one end of the power transmission member 10 close to the driven member 20 . The connecting column 13 is used to connect to one end of the first elastic member 40 .

[0095] In the embodiments provided by the present utility model, Figure 7 As shown, the electrical contacts 21 are provided on a chip board 23. A chip mounting portion 24 is provided on the driven component 20. The chip board 23 is provided on the first chip mounting portion 24, and the chip board 23 extends perpendicularly to the second direction D2. The first chip mounting portion 24 is provided at the end of the driven component 20 that faces the inner sidewall of the image forming device. Because the chip board 23 extends vertically or nearly vertically, the electrical contacts 21 maintain a large contact surface with the body contacts 60, and the springs on which the body contacts 60 are located are less likely to slip off the electrical contacts 21.

[0096] In a feasible embodiment, the electrical contacts 21 on the driven part 20 can also be adapters between the processing box chip and the printer's main body contacts 60. Specifically, the processing box also includes a chip board and a second chip mounting portion, and the second chip mounting portion is used to mount the chip board; when the chip board is mounted on the second chip mounting portion, the electrical contacts 21 of the driven part 20 are also used to electrically connect with the contacts of the chip board.

[0097] Multiple processing cartridges can be installed in the image forming device to achieve presentation of different colors. The driven members 20 at the ends of the processing cartridges of different colors can extend forward to different distances, and need to be set according to actual conditions to form a stepped arrangement.

[0098] Based on the above embodiments, the processes of electrically connecting and disconnecting the process cartridge provided by the present invention and the image forming device are as follows:

[0099] After the processing box is installed to the mounting part of the image forming device, the driven part 20 is initially in the first position, the electrical contact 21 is not electrically connected to the main body contact 60, the driving part 30 starts to rotate downward, and after the abutting part 31 abuts against the power transmission part 10, the driving power transmission part 10 starts to move downward. As the driving part 30 continues to rotate, the power transmission part 10 continues to apply force to the driven part 20. Under the action of the pushing part 11 and the forced pushing part 22, the driven part 20 moves toward the inner side wall of the image forming device. When the driven part 20 reaches the second position, the electrical contact 21 is electrically connected to the main body contact 60.

[0100] When the processing box needs to be pulled out, the driving member 30 rotates upward, and the abutment portion 31 and the power transmission member 10 are no longer in abutment with each other. The elastic force accumulated by the first elastic member 40 in the process of the power transmission member 10 moving downward acts on the power transmission member 10, so that the power transmission member 10 returns to its original position. The second elastic member also releases the elastic force to the driven member 20, so that the driven member 20 returns to the first position from the second position, and the electrical contact 21 no longer contacts the main body contact 60.

[0101] The following introduces other embodiments of process cartridges, which, like the process cartridge provided by the present invention, can solve the problem of protecting electrical contacts from wear.

[0102] Example 1

[0103] A sponge block is installed under the processing cartridge chip / chip contact. When the processing cartridge is not installed in the image forming device, the processing cartridge chips / chip contacts of each color are ensured to extend to the same height under the action of the sponge.

[0104] When the processing box is installed in the image forming device and the processing box chip contacts come into contact with the main body electrical contacts, the sponge is compressed to different heights at different positions of the processing box chip / chip contacts under the action of force, ensuring stable contact between the processing box chip and the main body electrical contacts at each position.

[0105] Example 2

[0106] The chips / chip contacts on each color process cartridge are at the same height. When each color process cartridge is installed in the image forming device, the chip contacts on each process cartridge make interference contact with the electrical contacts on the main body. In this solution, the chip contacts are made of rigid material to increase the wear resistance between the chip contacts and the main body electrical contacts, ensuring normal chip communication when the process cartridge is installed within the image forming device. Alternatively, the height of the bracket supporting the chip / chip contacts on the process cartridge is designed to have a certain tolerance within the manufacturing tolerance range. This tolerance is used to reduce friction between the chip contacts of the process cartridge and the electrical contacts of the main body, ensuring normal communication between the chip contacts of the process cartridge and the electrical contacts of the main body.

[0107] Example 3

[0108] When the processing boxes are produced, it is ensured that the chip contacts of two processing boxes of adjacent colors in one group remain the same in protruding height. When the processing boxes are installed in the image forming device, there is a group of processing boxes among the four processing boxes with the chip contacts protruding at the same height. When they come into contact with the contacts of the main body, the interference fit is used to ensure normal communication between the main body and the processing box chip.

[0109] In a third aspect, the present invention provides an image forming device comprising the aforementioned process cartridge. During installation and removal of the process cartridge from the image forming device, the electrical contacts 21 at the ends of the process cartridge do not contact the body contacts 60 on the inner sidewall of the image forming device, thereby protecting the electrical contacts 21 and reducing wear. Furthermore, the conductive contact of the chip of the process cartridge remains stable, and the image forming device can recognize the chip of the process cartridge and operate normally, thereby improving the imaging effect of the image forming device and extending its service life.

[0110] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
