Description

Technical Field

[0001] The present application relates to the field of image forming technology, and in particular to an image forming device. Background Art

[0002] An image forming device is a device that forms an image on a print medium based on input signals. Examples include printers, copiers, fax machines, and multifunction printers that integrate printer, copier, and fax functions. The image forming device's body houses a process cartridge. As printing consumables, the process cartridge frequently requires removal and replacement. Therefore, a removable door is provided on the body to allow access to the process cartridge. A chip in the process cartridge establishes an electrical connection with the body, allowing the printer's mainboard to obtain information about the process cartridge.

[0003] During the process of disassembling and assembling the processing box, the friction between the electrical connection contacts of the processing box chip and the body will cause the chip to be worn, affecting the recognition effect. Utility Model Content

[0004] The present application provides an image forming device for solving the problem of chip wear caused by friction between electrical connection points of a processing box chip and a machine body.

[0005] An embodiment of the present application provides an image forming device, comprising:

[0006] a processing box having a chip thereon;

[0007] A motion assembly, the motion assembly comprising a rotating member, the rotating member being provided with an electrical contact, the rotating member being capable of rotating so that the electrical contact abuts against the chip;

[0008] a valve, wherein when the valve is opened, the rotating member is driven to rotate in a first direction, so that the electrical contact moves away from the chip, and the process cartridge can be installed in or removed from the image forming device;

[0009] When the shutter is closed, the rotating member is driven to rotate in the second direction, so that the electrical contact moves toward the chip.

[0010] In one possible design, the motion component further includes an elastic member, which enables the rotating member to maintain a first state away from the chip and a second state abutting the chip. When the rotating member moves from the first state to the second state or from the second state to the first state, the elastic force exerted by the elastic member on the rotating member first increases and then decreases.

[0011] In one possible design, the first end of the elastic member is connected to a fixed component other than the rotating member in the image forming device, and the second end of the elastic member is connected to a rotating end of the rotating member. When the rotating member rotates, the first end of the elastic member is fixed and the second end swings with the rotating member.

[0012] When the rotating member moves to a certain specific position between the first state and the second state, the first end and the second end of the elastic member and the rotating axis of the rotating member are located on the same plane. At this time, the elastic force of the elastic member reaches the maximum value of the elastic force change. In the first state and the second state, the connection points between the second end of the elastic member and the rotating end are respectively located on both sides of the plane.

[0013] In a possible design, the image forming device further includes a shielding member, which is used to limit the rotation distance of the rotating member in the first direction, and the position where the rotating member is stopped by the shielding member is the position of the first state.

[0014] In a possible design, the electrical contact includes an annular ring and a connecting portion, the outer peripheral extension direction of the annular ring is arranged in the same direction as the rotation direction of the rotating member, and the connecting portion is used to connect the annular ring to the rotating member.

[0015] In a possible design, the connecting portion is elastic and is used to provide a thrust to the annular ring toward the chip.

[0016] In a possible design, the valve is provided with a driving portion, and the rotating member is correspondingly provided with a driven portion;

[0017] When the valve is opened, the driving portion drives the rotating member to rotate along the first direction through the driven portion. When the valve is closed, the driving portion drives the rotating member to rotate along the second direction through the driven portion.

[0018] In one possible design, the valve is an upper cover arranged on the top of the image forming device, the processing box is installed in the image forming device through the opening when the upper cover is opened, and when the processing box is installed in the image forming device, the chip faces below the plane where the chip is located.

[0019] In a possible design, the driving portion is a protrusion protruding downward from the upper cover, the side surface of the protrusion is recessed inward to form a hook portion, and the upper surface of the recess forms the pressing portion;

[0020] The driven part and the electrical contact are respectively located at two ends of the rotating member, and the rotating shaft of the rotating member is located between the driven part and the electrical contact;

[0021] When the upper cover is rotated upward to open, the hook portion hooks the driven portion upward to cause the electrical contact to rotate downward and separate from the chip;

[0022] When the upper cover is rotated downward and closed and the processing box is installed in the image forming device, the pressing portion presses the driven portion downward to cause the electrical contact to rotate upward until it abuts against the chip and stops, and when the upper cover is completely closed, the driven portion stops in the recess.

[0023] In one possible design, the process cartridge includes a photosensitive drum, and the chip is disposed on an outer surface of the process cartridge and on a side facing away from the photosensitive drum.

[0024] In the present application, the opening of the valve causes the rotating member to rotate in a first direction, separating the electrical contacts from the chip and simultaneously exposing the installation location of the process cartridge within the image forming device, allowing an operator to install or remove the process cartridge. During the installation and removal of the process cartridge, since the electrical contacts are separated from the chip, there is no friction between the electrical contacts and the chip, which does not cause wear of the electrical contacts or the chip, and thus does not affect the image forming device's ability to recognize the chip.

[0025] The closing of the valve drives the rotating member to rotate in a second direction (the second direction is opposite to the first direction), allowing the electrical contacts to contact the chip while simultaneously shielding the installation location of the process cartridge within the image forming device, providing protection for the process cartridge. The relationship between the contact and separation of the electrical contacts and the chip and the opening and closing of the valve facilitates the control of the contact and separation between the electrical contacts and the chip.

[0026] It should be understood that the foregoing general description and the following detailed description are merely illustrative and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0066] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0067] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0068] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0069] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0070] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.

[0071] The present application provides an image forming device, such as Figures 1 to 3 As shown, the image forming device 1 includes: a processing box 3, a moving component 2 and a valve, and a chip 31 is provided on the processing box 3; the moving component 2 includes a rotating member 21, and an electrical contact 4 is provided on the rotating member 21. The rotating member 21 can be rotated so that the electrical contact 4 abuts against the chip 31; when the valve is opened, the rotating member 21 is driven to rotate along a first direction P, so that the electrical contact 4 moves away from the chip 31, and the processing box 3 can be installed or removed in the image forming device 1; when the valve is closed, the rotating member 21 is driven to rotate along a second direction, so that the electrical contact 4 moves toward the chip 31.

[0072] In this embodiment, the opening of the shutter causes the rotating member 21 to rotate in the first direction P, separating the electrical contacts 4 from the chip 31. This simultaneously exposes the installation location of the process cartridge 3 within the image forming apparatus 1, allowing the operator to install or remove the process cartridge 3. During the installation and removal of the process cartridge 3, since the electrical contacts 4 are separated from the chip 31, no friction is generated between them, resulting in no wear of the electrical contacts 4 or the chip 31, and thus no impact on the image forming apparatus 1's ability to recognize the chip 31.

[0073] The closing of the shutter drives the rotating member 21 to rotate in a second direction (the second direction is opposite to the first direction P), causing the electrical contacts 4 to contact the chip 31. This simultaneously shields the installation location of the process cartridge 3 within the image forming apparatus 1, thus protecting the process cartridge 3. The interrelationship between the contact and separation between the electrical contacts 4 and the chip 31 and the opening and closing of the shutter facilitates control of the contact and separation between the electrical contacts 4 and the chip 31.

[0074] Specifically, such as Figures 3 to 5 As shown, the motion assembly 2 further includes an elastic member 22. The first end of the elastic member 22 is connected to a fixed component other than the rotating member 21 in the image forming apparatus 1, and the second end of the elastic member 22 is connected to the rotating end 211 of the rotating member 21. When the rotating member 21 rotates, the first end of the elastic member 22 remains stationary, while the second end swings with the rotating member 21, so that the electrical contact 4 can move closer to or further away from the chip 31 as the rotating member 21 swings. The driving member 22 may be a spring, a tension spring, or the like.

[0075] During the rotation of the rotating member 21, the elastic member 22 is always in a stretched state, so the second end of the elastic member 22 always applies an elastic force to the rotating member 21. The elastic force applied by the second end of the elastic member 22 to the rotating member 21 enables the rotating member 21 to maintain a first state away from the chip 31 and a second state abutting the chip 31.

[0076] Figure 3 The diagram shows a first state where the electrical contact 4 is away from the chip 31. In the first state, the force exerted by the elastic member 22 on the rotating member 21 causes the rotating member 21 to move away from the chip 31, so that the electrical contact 4 and the chip 31 remain separated.

[0077] Figure 4 The second state is shown, where the electrical contact 4 abuts against the chip 31. In the second state, the force exerted by the elastic member 22 on the rotating member 21 moves the rotating member 21 toward the chip 31, so that the electrical contact 4 and the chip 31 remain in contact.

[0078] When the rotating member 21 moves from the first state to the second state or from the second state to the first state, the elastic force of the elastic member 22 acting on the rotating member 21 first increases and then decreases.

[0079] When the rotating member 21 moves to a specific position between the first state and the second state, the first end and the second end of the elastic member 22 and the rotating shaft 111 of the rotating member 21 are located on the same plane. At this time, the elastic force of the elastic member 22 reaches the maximum value of the elastic force change. In the first state and the second state, the connection points between the second end of the elastic member 22 and the rotating end 211 are respectively located on both sides of the plane.

[0080] Figure 5 FIG. 2 shows a state where the first end and the second end of the elastic member 22 and the rotation axis of the rotating member 21 are located in the same plane (balanced state). Figure 5 As shown, the direction of the force exerted by the second end of the elastic member 22 on the rotating member 21 is parallel to the plane in which the first end, the second end, and the rotation axis of the rotating member 21 lie. That is, at this time, the force exerted by the elastic member 22 on the rotating member 21 does not drive the rotating member 21 to rotate. At this time, the length of the elastic member 22 is the longest. Therefore, when the first end, the second end, and the rotation axis of the rotating member 21 are in the same plane, the elastic force of the elastic member 22 reaches the maximum elastic force variation.

[0081] like Figure 3 As shown, in the first state, the elastic member 22 does not overlap with the rotating shaft 111 of the rotating member 21, and the elastic member 22 is located below the rotating shaft 111, so that the elastic force exerted by the second end of the elastic member 22 on the rotating member 21 drives the rotating member 21 to rotate along the first direction P.

[0082] like Figure 4 As shown, in the second state, the elastic member 22 does not overlap with the rotating shaft 111 of the rotating member 21, and the elastic member 22 is located above the rotating shaft 111, so that the elastic force exerted by the second end of the elastic member 22 on the rotating member 21 drives the rotating member 21 to rotate along the second direction.

[0083] It is understandable that the opening of the valve will drive the rotating member 21 to Figure 4 The status shown Figure 5 The status shown turns to Figure 3 In the state shown, the action of closing the valve will drive the rotating member 21 to Figure 3 The status shown Figure 5 The status shown turns to Figure 4 Status shown.

[0084] In addition, if Figure 4 As shown, when the valve is closed, the force applied by the rotating member 21 to the valve is in the second direction, which is helpful to keep the valve in a closed state more stably.

[0085] Furthermore, a driving portion 121 is provided on the valve, and a driven portion 212 is correspondingly provided on the rotating member 21; when the valve is opened, the driving portion 121 drives the rotating member 21 to rotate along the first direction P through the driven portion 212, and when the valve is closed, the driving portion 121 drives the rotating member 21 to rotate along the second direction through the driven portion 212.

[0086] Figure 6 FIG shows the state of the motion component 2 before it reaches the first state after the equilibrium state. Figure 6 As shown, the elastic member 22 does not coincide with the rotation axis 111 of the rotating member 21 , and the elastic member 22 is located below the rotation axis 111 , so that the elastic force exerted by the elastic member 22 on the rotating member 21 drives the rotating member 21 to rotate along the first direction P.

[0087] During the opening process of the valve, the elastic force can assist the valve in opening, reducing the force required to open the valve and improving the user experience. During the closing process of the valve, the elastic force can hinder or slow down the closing of the valve, reducing the noise generated during the closing process and preventing the valve from pinching the user's fingers.

[0088] Figure 7 FIG shows the state of the motion component 2 before it reaches the second state after the equilibrium state. Figure 7 As shown, the elastic member 22 does not coincide with the rotation axis 111 of the rotating member 21 , and the elastic member 22 is located above the rotation axis 111 , so that the elastic force exerted by the elastic member 22 on the rotating member 21 drives the rotating member 21 to rotate along the second direction.

[0089] During the closing process of the valve, this elastic force assists the valve in closing, achieving automatic closing of the valve. After the valve is closed, this elastic force drives the rotating member 21 to bring the electrical contact 4 close to the chip 31 and eventually abut against the chip 31. That is, the electrical contact 4 will only abut against the chip 31 when the valve is in the closed state. At this time, the user cannot touch the process cartridge 3, thereby preventing the user from electric shock and protecting the user's safety.

[0090] Furthermore, Figure 8 As shown, the image forming apparatus 1 further includes a blocking member 113 , which is used to limit the rotation distance of the rotating member 21 in the first direction P. The position where the rotating member 21 is stopped by the blocking member 113 is the position of the first state.

[0091] like Figure 8 As shown, a limiting portion 113a is provided on the shielding member 113, and the limiting portion 113a can abut against the rotating member 21 to limit the continued rotation of the rotating member 21, so that the rotating member 21 can remain in the first state after the valve is opened.

[0092] It can be understood that the shielding member 113 can cover at least part of the moving component 2. On the one hand, it reduces the user's contact with the internal structure of the body 11 when the user disassembles and replaces the processing box 3, preventing the user from damaging the image forming device 1 due to accidental touch. On the other hand, it makes the structure inside the body visible to the user simpler.

[0093] In one embodiment, the image forming apparatus 1 includes a main body 11 and an upper cover 12 rotatably connected to the main body 11, the upper cover 12 serving as a valve. The process cartridge 3 is installed within the main body 11 through an opening formed by the upper cover 12 when it is open. When the process cartridge 3 is installed within the main body 11, the chip 31 faces downward from the plane where the chip 31 resides.

[0094] Since the chip 31 faces downward from the plane where the chip 31 is located, powder leaked from the process box 3 will not stick to the chip 31 , thereby preventing poor contact between the chip 31 and the electrical contact 4 .

[0095] Furthermore, the driving portion 121 is a protrusion protruding downward from the upper cover 12 , the side surface of the protrusion is recessed inward to form a hook portion 121 a , and the recessed upper surface forms a pressing portion 121 b .

[0096] The driven portion 212 and the electrical contact 4 are respectively located at two ends of the rotating member 21 , and the rotating shaft 111 of the rotating member 21 is located between the driven portion 212 and the electrical contact 4 , so that the electrical contact 4 can be moved by applying a force to the driven portion 212 .

[0097] When the upper cover 12 is rotated upward to open, the hook portion 121a hooks the driven portion 212 upward, causing the electrical contact 4 to rotate downward and separate from the chip 31. That is, the rotating member 21 is moved downward under the action of the hook portion 121a of the driving portion 121. Figure 4 The status shown Figure 5 The status shown turns to Figure 6 Then the driving part 121 is separated from the driven part 212, and the rotating member 21 is rotated to Figure 3 The first state is shown.

[0098] When the upper cover 12 is rotated downward and closed and the process cartridge 3 is installed in the image forming apparatus 1, the pressing portion 121b presses the driven portion 212 downward to rotate the electrical contact 4 upward until it abuts against the chip 31 and stops. When the upper cover 12 is completely closed, the driven portion 212 stops in the recess, that is, after the rotating member 21 abuts against the pressing portion 121b, the rotating member 21 is pressed by the pressing portion 121b. Figure 6 The status shown Figure 5 The status shown turns to Figure 4 Status shown.

[0099] exist Figure 4 In the state shown, the driven portion 212 abuts against the hook portion 121 a , and the hook portion 121 a limits the rotation of the driven portion 212 along the second direction, so that the driven portion 212 stops in the recess, and the rotating member 21 remains in the second state.

[0100] In addition, the shielding member 113 has an escape groove 113b, into which the driven portion 212 and the driving portion 121 can extend, preventing the shielding member 113 from obstructing the movement of the driven portion 212 and the driving portion 121. At the same time, the escape groove 113b can also guide the movement of the driven portion 212 and the driving portion 121.

[0101] Optionally, the body 11 has a mounting portion 112 with a mounting hole, and the first end of the elastic member 22 is fixedly connected to the body 11 through the mounting portion 112. The rotating end 211 is provided with a hook 211a, and the second end of the elastic member 22 can be connected to the rotating end 211 through the hook 211a.

[0102] Optional, such as Figure 9 As shown, the driven portion 212 includes an extension portion 212a and a force-bearing portion 212b. The force-bearing portion 212b is connected to one end of the extension portion 212a away from the axial hole 213. The extension direction of the extension portion 212a is different from the extension direction of the force-bearing portion 212b, so that the driving portion 121 can contact the force-bearing portion 212b and apply force to the force-bearing portion 212b.

[0103] The angle between the extending direction of the extending portion 212a and the extending direction of the force-bearing portion 212b may be a right angle, an obtuse angle close to a right angle, or an acute angle.

[0104] Optionally, the mounting portion 112 is connected to the shielding member 113 and may be integrally formed with the shielding member 113 .

[0105] In a specific embodiment, Figure 10 As shown, the electrical contact 4 includes an annular ring 41 and a connecting portion 42 . The outer peripheral extension direction of the annular ring 41 is arranged in the same direction as the rotation direction of the rotating member 21 . The connecting portion 42 is used to connect the annular ring 42 to the rotating member 21 .

[0106] In this embodiment, when the rotating member 21 drives the electrical contact 4 close to the chip 31, the annular ring 41 can abut against the chip 31, thereby achieving communication between the body 11 and the process cartridge 3. The outer periphery of the annular ring 41 extends in the same direction as the rotation direction of the rotating member 21, thereby facilitating the rotating member 21 to drive the annular ring 41 into contact with or separate from the chip 31.

[0107] Furthermore, the connecting portion 42 is elastic, providing a thrust to the annular ring 41 against the chip 31. One end of the connecting portion 42 is connected to the movable end of the rotating member 21, and the other end is connected to the annular ring 41. When the annular ring 41 abuts the chip 31, the connecting portion 42 applies an elastic force to the annular ring 41. This elastic force pushes the annular ring 41 against the chip 31, improving the reliability of the electrical connection between the electrical contact 4 and the chip 31.

[0108] The connecting portion 42 may be elastic rubber, silicone or a spring.

[0109] Furthermore, the electrical contact 4 further includes a protective shell 43 having a mounting cavity. The mounting cavity houses a portion of the rotating end 211, a portion of the annular ring 41, and the connecting portion 42. The mounting cavity has multiple openings through which the annular ring 41 can pass to connect to the connecting portion 42. The openings also serve to separate and limit the annular ring 41.

[0110] In a specific embodiment, the process cartridge 3 includes a photosensitive drum 32 , and the chip 31 is disposed on an outer surface of the process cartridge 3 and on a side facing away from the photosensitive drum 32 .

[0111] At least a portion of the photosensitive drum 32 is exposed outside the process cartridge 3. When the process cartridge 3 is installed in the image forming apparatus 1, the photosensitive drum 32 is able to contact an intermediate transfer belt (not shown) within the image forming apparatus to transfer the toner image formed on the photosensitive drum 32 to the intermediate transfer belt. The chip 31 is disposed on the outer surface of the process cartridge 3, facing away from the photosensitive drum 32. This prevents any toner powder from the photosensitive drum 32 from coming into contact with the chip 31 and adhering to it, thereby affecting the electrical connection between the chip 31 and the electrical contacts 4.

[0112] In order to facilitate the abutment between the electrical contacts 4 and the chip 31 , the moving assembly 2 and the electrical contacts 4 are also arranged on the side of the processing box 3 facing away from the photosensitive drum 32 .

[0113] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
