Description

Technical Field

[0001] This invention relates to the field of electrophotographic imaging, and more particularly to a processing box that can be detachably installed in an electrophotographic imaging device. Background Technology

[0002] Chinese patent application CN113574469A (hereinafter referred to as the cited patent application) discloses a force output component (main component side driving force transmission unit) 203 disposed in an imaging device M, such as Figure 2E (Cited patent application) Figure 43 As shown in the figure, the force output member 203 has a rotation axis M1 and includes a driving force output member (drum drive coupling) 180 that outputs driving force and a braking force output member (including a first braking coupling member 204 and a second braking coupling member 208) that outputs braking force. When the force output member 203 outputs driving force to the driving force receiving member X4 described below, the braking force output member is driven by the driving force output member 180 and rotates together with the driving force output member.

[0003] like Figure 2G (Cited patent application) Figure 45 As shown in the figure, along the rotation axis M1, the two ends of the driving force output component 180 are respectively provided with a driving force output surface (driving transmission surface) 180d and a flange portion 180a; as Figure 2E As shown, the first braking coupling member 204 has a flange portion 204a and a coupling coupling portion 204b protruding from the flange portion 204a. The coupling coupling portion 204b is configured to protrude like a claw toward the rotation axis M1 of the force output member. The second braking coupling member 208 also has a flange portion 208a and a coupling coupling portion 208b protruding from the flange portion 208a. The coupling coupling portion 208b is also configured to protrude like a claw toward the rotation axis M1 of the force output member. Along a radial direction perpendicular to the rotation axis M1, the first braking coupling member 204 is located outside the second braking coupling member 208, and the coupling coupling portion 204b is located outside the coupling coupling portion 208b. The first braking coupling member 204 and the second braking coupling member 208 can rotate simultaneously about the rotation axis M1.

[0004] Figure 1 It is a perspective view of a rotating component with an existing drive force receiver installed.

[0005] The Chinese patent application CN113574469A also discloses, as follows: Figure 1The diagram shows a rotating member 21 fitted with an existing drive force receiver X4. The rotating member 21 and the drive force receiver X4 are adapted to an existing processing box, which includes a first unit and a second unit coupled together, and a drive force receiver X4 for receiving drive force from an imaging device. The first unit includes a first unit housing and a first rotating member 11 rotatably mounted in the first unit housing. The second unit includes a second unit housing and a second rotating member 21 rotatably mounted in the second unit housing. The drive force receiver is disposed at a longitudinal end of the processing box C and drives at least one of the first rotating member 11 and the second rotating member 21 to rotate.

[0006] Taking the rotation of the second rotating component 21 around the rotation axis L21 as an example, as follows Figure 1 As shown, the driving force receiving component X4 is combined with the second rotating component 21, including a chassis X42, a base X43 and a connecting part X44. Along the rotation axis L21, the chassis X42, the base X43 and the connecting part X44 are arranged in sequence. The connecting part X44 includes a central column X45 and a driving force receiving part X46 extending radially outward along the central column X45. The driving force receiving part X46 is provided with a guide surface X463 that extends spirally in the circumferential direction around the rotation axis L21, and a driving surface X464 and a braking surface X465 that are adjacent to the guide surface. Along the rotation axis L21, the guide surface X463 is located above the braking surface X465.

[0007] During the installation of the processing box C, the guide surface X463 abuts against at least the coupling engagement portion 208b in the second braking engagement member 208 to guide the driving force receiving part X46 into the space between the driving force output surface 180d and the coupling engagement portion 208b / 204b; when the processing box C is in operation, the driving force output surface 180d outputs driving force to the driving surface X464 to drive the rotating member 21 to rotate, and the braking force output member is used to apply braking force to the braking surface X465 downstream of the rotation direction of the driving force receiving part X46.

[0008] Processing boxes typically contain a chip for storing processing box information and a charging electrode assembly for powering the charging components. The chip has electrical contacts that are electrically connected to the imaging device, while the charging electrode assembly includes charging electrodes that are electrically connected to the imaging device. The charging electrodes and electrical contacts are usually located at both ends of the processing box or in different directions. This design makes the electrical components of the matching imaging device more complex, and the charging electrodes or electrical contacts near the drive end are easily affected by the movement of the imaging device's drive head during operation, which can affect the stability of the electrical connection. Utility Model Content

[0009] This invention provides a processing box to further develop the above-mentioned technology, the specific solution of which is as follows:

[0010] A processing cartridge, detachably mounted in an imaging device, includes: a driving force receiver; a housing having a driving end on one side where the driving force receiver is located and a non-driving end on the opposite side; a photosensitive drum rotatably disposed within the housing, the photosensitive drum being driven by a driving force received by the driving force receiver, the driving force receiver being exposed from the driving end; a charging unit for charging the photosensitive drum; a charging electrode assembly including a power receiving part for receiving power and a power transmitting part for electrically connecting to the charging unit, the power receiving part being electrically connected to the power transmitting part; a chip including a storage part storing processing cartridge information and an electrical contact part electrically connected to the storage part; and a developing roller rotatably disposed within the housing, the photosensitive drum and the developing roller being mounted on the lower side of the housing; wherein the electrical contact part and the power receiving part are disposed above the non-driving end and exposed upwards towards the housing.

[0011] In some embodiments, the housing includes a first unit housing, a second unit housing, and a second end cover mounted on the non-driving end. The second end cover is combined with the first unit housing and the second unit housing. An electrical contact portion is disposed on the second end cover, and a charging electrode assembly is disposed on the second unit housing.

[0012] In some embodiments, both the electrical contact and the power receiving part face upwards.

[0013] In some embodiments, the housing includes a first unit housing, a second unit housing, and a second end cover mounted on the non-driving end. The second end cover is combined with the first unit housing and the second unit housing. The second end cover is also provided with an electrical contact cavity, in which at least the power receiving part is located.

[0014] In some embodiments, the imaging device further includes a door cover and a top plate provided with a power output component and a stylus, both of which are exposed downwards. Before the door cover is closed, the top plate does not abut against the processing box. When the door cover is closed, the top plate abuts against the processing box, and the electrical contact part is electrically connected to the stylus, and the power receiving part is also electrically connected to the power output component.

[0015] In some embodiments, the power receiving part is in contact with the lower conductive surface or the side conductive surface of the power output part.

[0016] In some embodiments, the processing box further includes a toggle member for toggling the power receiving unit, causing the power receiving unit to switch from a first state where it cannot receive power to a second state where it can receive power.

[0017] In some embodiments, the charging component is rotatably supported on the housing by a bracket, and a spring is provided between the bracket and the housing. The charging component is kept in contact with the photosensitive drum by the pushing force of the spring.

[0018] In some embodiments, the processing box further includes a friction element disposed adjacent to and in contact with the charging element, the friction element extending along the rotation axis of the driving force receiver, and the charging element being rotatably supported on the housing by a bracket.

[0019] In some embodiments, the charging component is driven to rotate by the frictional force between the surface of the photosensitive drum and the surface of the charging component. When the charging component loses its power source, the frictional force between the friction element and the charging component forces the charging component, which continues to rotate due to inertia, to stop rotating.

[0020] In some embodiments, the friction element is an elastic component.

[0021] In some embodiments, the friction element is configured as a sponge.

[0022] In some embodiments, the imaging device further includes a force output member, which includes a driving part and a braking part, and the braking part is rotatable together with the driving part. The driving force receiving member includes a driving force receiving part and an auxiliary part, which is used to engage with the force output member to receive driving force. The auxiliary part is configured to be rotatable about the rotation axis of the driving force receiving member, and at least a portion of the auxiliary part is used to separate the driving part and the braking part in the rotation direction of the force output member.

[0023] In some embodiments, the auxiliary member is configured to be movable along the rotation axis of the driving force receiver.

[0024] In some embodiments, the driving force receiving member further includes a joint portion and a base that are joined together. The driving force receiving portion is disposed in the joint portion, and the base is cylindrical and includes an outer wall and an inner wall of the base that are radially arranged and form a spacer groove between them. A portion of the auxiliary member is accommodated by the spacer groove.

[0025] In some embodiments, the driving force receiving member further includes a main body portion on which the driving force receiving portion is provided, at least a portion of which is accommodated by an auxiliary member; the auxiliary member is provided with a limiting portion, and the main body portion is provided with a limiting portion for engaging with the limiting portion.

[0026] In some embodiments, the auxiliary component includes a carrier and a separating component protruding from the carrier. The limited portion is disposed on the carrier or the separating component. The auxiliary component is sleeved on the outside of the main body. The separating component is provided with a guide surface. During the movement of the driving force receiving component toward the force output component, the guide surface abuts against the braking component and forces the braking component away from the driving component in the rotation direction.

[0027] In some embodiments, the separator is further provided with a barbed surface for engaging with the braking part, the barbed surface being used to prevent the force output part from separating from the driving force receiving part.

[0028] In some embodiments, the separator includes a separator body and a tip that are joined together, a guide surface is disposed on the separator body, and the tip extends from the guide surface in a direction further away from the carrier.

[0029] In some embodiments, the auxiliary component is fitted onto the housing.

[0030] In some embodiments, when the driving force receiving member and the force output member are fully engaged, at least a portion of the auxiliary member enters the space between the driving part and the braking part, and the driving force receiving member engages with the driving part or the braking part.

[0031] The beneficial effects of this invention are as follows: Compared to the existing technology that places the power receiving part on the side of the processing box end cover, this embodiment innovatively integrates the charging electrode assembly onto the second unit housing and fixes it with the power receiving part facing upwards (top plate). This design eliminates the need for electrode exposure openings on the second end cover, thus avoiding structural weaknesses caused by openings. This not only simplifies the design and manufacturing process of the end cover but also significantly enhances the overall strength and impact resistance of the second end cover, improving the reliability and service life of the device.

[0107] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. For ease of understanding, except for the driving force receiving element, the numbering and structure of the processing box and its components mentioned in the background patent application will be directly referenced below.

[0108] like Figure 3A and Figure 3B As shown, the processing box C includes a first unit 100 and a second unit 200. The first unit 100 includes a first unit housing 1 and a first rotating member 11 rotatably mounted in the first unit housing 1. The second unit 200 includes a second unit housing 2 and a second rotating member 21 rotatably mounted in the second unit housing 2. The housing of the processing box C includes the first unit housing 1, the second unit housing 2, a first end cap 300, and a second end cap 400. A driving force receiving member 4 is disposed at one longitudinal end of the processing box C and drives at least one of the first rotating member 11 and the second rotating member 21 to rotate.

[0109] It is understood that the first rotating member 11 and / or the second rotating member 21 can be directly driven by the driving force receiving member 4 or indirectly driven; the processing box C can include both the first unit 100 and the second unit 200, or only either the first unit 100 or the second unit 200. The developer is contained in the first unit housing 1. The side where the driving force receiving member 4 is provided is called the driving end C1, and the opposite end is called the non-driving end C2. The driving end cover / first end cover 300 is installed on the driving end C1, and the driving force receiving member 4 is exposed from the driving end C1. The non-driving end cover / second end cover 400 is installed on the non-driving end C2. The first unit 100 and the second unit 200 can be connected to each other through the first end cover 300 and the second end cover 400, or they can be connected by means such as pins or buckles. The first end cover 300 and the second end cover 400 can be part of the first unit 100 or the second unit 200, or they can be components independent of the first unit 100 or the second unit 200, as long as the first unit 100 and the second unit 200 can be connected. The components 200 can be combined. The first end cap 300 is combined with the first unit housing 1 and the second unit housing 2, and the second end cap 400 is also combined with the first unit housing 1 and the second unit housing 2. The first rotating component 11 can be a developing roller rotatably disposed in the first unit housing 1, and the second rotating component 21 can be a photosensitive drum rotatably disposed in the second unit housing 2. However, the first rotating component 11 and the second rotating component 21 can also be other components in the processing box that need to rotate, such as a charging component 24 for charging the photosensitive drum, a supply component 102 for supplying developer to the developing roller, a stirring component for stirring the developer, etc. As long as the driving force receiving component 4 can receive driving force from the force output component provided in the imaging device and drive the rotating component to rotate, that is, the photosensitive drum 21, the charging component 24, the developing roller 11, the supply component 102, the stirring component, etc., which are rotatably installed in the processing box C can all be called rotating components. The driving force receiving component 4 drives the rotating component to rotate by receiving driving force from the device. Therefore, the combination of the rotating component and the driving force receiving component 4 can be collectively referred to as a rotating assembly.

[0110] When the processing cartridge C is in operation, the photosensitive drum 21 contacts the developing roller 11, and the developing roller 11 supplies developer to the photosensitive drum 21. In the following text, the driving force receiver is indicated by the number 4. The driving force receiver 4 is fixedly installed at one longitudinal end of the rotating component, so that the driving force receiver 4 and the rotating component have the same axis of rotation.

[0111] Figure 3A and Figure 3BThis is a perspective view of the processing cartridge according to the present invention. The processing cartridge C includes a first unit 100 and a second unit 200. The housing of the processing cartridge C includes a first unit housing 1, a second unit housing 2, a first end cap 300 and a second end cap 400. The rotating components include a photosensitive drum 21 and a developing roller 11 rotatably disposed in the housing.

[0112] For ease of description below, the following definitions apply: the side of the processing cartridge C where the photosensitive drum 21 and the developing roller 11 are installed, pointing towards the side where the photosensitive drum 21 and the developing roller 11 are not installed, is the upper side; the side opposite to the upper side is the lower side; the direction from the first unit 100 to the second unit 200 is the front side; the side opposite to the front side is the rear side; the side receiving the driving force is the left side; the side opposite to the left side is the right side; the processing cartridge C is installed in the device from top to bottom along the vertical direction; the left side is the driving end C1; the right side is the non-driving end C2; the first end cover 300 is installed on the driving end C1; the second end cover 400 is installed on the non-driving end C2; the first driving force receiver 3 (also referred to as the "developing driving force receiver 3") for receiving driving force for the developing roller 11 and the driving force receiver 4 for receiving driving force for the photosensitive drum 21 are both exposed from the first end cover 300.

[0113] Furthermore, the processing cartridge C also includes a reset member C3 disposed between the first unit 100 and the second unit 200. When a separation force is applied to the processing cartridge, the reset member C3 undergoes elastic deformation. When the separation force is removed, the reset member C3 releases its elastic force, and the developing roller 11 and the photosensitive drum 21 return to their contacting position.

[0114] The following description will take the example of the driving force receiver 4 being directly mounted at the end of the photosensitive drum 21.

[0115] Force output components in imaging equipment

[0116] To make the following description clearer, it is necessary to further describe the force output element 203 with reference to the drawings of the patent application (referenced patent application) described in the background art.

[0117] Figure 2A It is a 3D view of the existing force output component; Figure 2B It is a partial 3D view of the existing force output component; Figure 2C This is a partial 3D view of the existing force output components after the braking force output component has been hidden. Figure 2D This is a top view taken along the rotation axis of the existing force output component.

[0118] like Figures 2A-2DAs shown, the driving force output component 180 includes a cylindrical portion 180c and flange portions 180a and a driving portion 180h located at both ends of the cylindrical portion 180c, respectively. The braking force output component includes a first braking engagement member 204 and a second braking engagement member 208 that are coupled to each other. Figure 2I (Referencing patent application figure 48) and Figure 19 As shown, the driving force output component 180 and the braking force output component can rotate in the same direction about the rotation axis M1 along the rotation direction r, and the braking force output component can rotate together with the driving force output component 180. Before the processing box C is installed in the equipment, the driving force output component 180 and the braking force output component partially overlap.

[0119] The driving force output component 180 includes a first driving force output portion 180h and a second driving force output portion 180m arranged opposite to each other along the radial direction of the force output component. The braking force output component includes a first braking force output portion 203a and a second braking force output portion 203b arranged opposite to each other along the radial direction of the force output component, such as... Figure 2D As shown, along the rotation direction, the first driving force output unit 180h, the first braking force output unit 203a, the second driving force output unit 180m, and the second braking force output unit 203b are arranged sequentially.

[0120] like Figure 2D As shown, draw a dividing line x passing through the rotation axis M1, between the first braking force output section 203a and the second driving force output section 180m, and between the first driving force output section 180h and the second braking force output section 203b. Figure 2D In the diagram, the dividing line x separates the force output component 203 into a first force output section 2031 and a second force output section 2032. The first force output section 2031 includes a first driving force output section 180h and a first braking force output section 203a. The second force output section 2032 includes a second driving force output section 180m and a second braking force output section 203b. The first driving force output section 180h and the second driving force output section 180m have the same structure, as do the first braking force output section 203a and the second braking force output section 203b. The connection process between the driving force receiving component 4 and the first force output section 2031 and the second force output section 2032 is the same.

[0121] For ease of description, the following description takes the combination process of the first force output unit 2031 and the driving force receiving unit 4 as an example; further, the first driving force output unit 180h in the first force output unit 2031 is simply referred to as the driving force output unit / driving unit 180h, and the first braking force output unit 203a in the first force output unit 2031 is simply referred to as the braking unit 203a. Along the rotation direction r, the braking unit 203a is located downstream of the driving unit 180h. The driving unit 180h and the braking unit 203a can rotate in the same direction around the rotation axis M1, and the braking unit 203a can rotate together with the driving unit 180h. Before the processing box is installed on the device, the driving unit 180h and the braking unit 203a partially overlap.

[0122] The braking unit 203a includes a first braking engagement member 204 and a second braking engagement member 208. Along the radial direction of the force output member 203, the first braking engagement member 204 is located outside the second braking engagement member 208, such as... Figure 2E As shown, the first braking coupling member 204 and the second braking coupling member 208 are coupled through the rotation stop recess 204c and the rotation stop protrusion 208c. Therefore, the first braking coupling member 204 and the second braking coupling member 208 can rotate together around the axis M1.

[0123] Furthermore, the force output component 203 also includes a first spring (drum drive coupling spring) 210 and a second spring (brake engagement spring) 211. The first spring 210 abuts against the brake transmission component 207, and the flange portion 207a of the brake transmission component 207 abuts against the second brake engagement component 208. Simultaneously, as... Figure 2F (Cited patent application) Figure 44 As shown, the protrusion 207f of the brake transmission member 207 also abuts against the contact surface 180f of the drive force output member; the second spring 211 abuts against the flange portion 204a of the first brake coupling member 204. Along the axis M1, the first brake coupling member 204, the second brake coupling member 208, and the drive portion 180h are configured to retract and extend along the axis M1, that is, along... Figure 2IThe first braking structure 204 and the second braking connecting member 208 can both retract and extend along axis M1 simultaneously. In some imaging devices, they can also retract and extend along axis M1 separately. When the first braking connecting member 204 moves along axis M1 in the direction shown in M1A (near the flange portion 180a), the rotation stop recess 204c and the rotation stop protrusion 208c disengage, and the first braking connecting member 204 can rotate freely around axis M1. When the second braking connecting member 208 moves along axis M1 in the direction shown in M1A, the first braking connecting member 204 will also move along axis M1 in the direction shown in M1A through the rotation stop recess 204c and the rotation stop protrusion 208c. Finally, both the first braking connecting member 204 and the second braking connecting member 208 can rotate freely around axis M1.

[0124] Furthermore, such as Figure 2H (Referencing patent application figure 47) and Figure 2D As shown, the second braking coupling member 208 also has an inwardly projecting portion 208e that protrudes radially inward from the coupling coupling portion 208b, and an inwardly projecting portion 208e along M1B (as shown in M1A) in the opposite direction to M1A. Figure 2I As shown in the diagram, the inwardly protruding portion 208e is located at the free end of the second braking coupling member 208. Figures 2A-2D As shown, the driving force output surface 180d is located on the driving part 180h. Along the rotation direction of the force output member 203, the driving part 180h is opposite to the first braking engagement member 204. That is, with the point through which the rotation axis M1 passes as the center, a circle is drawn in a plane perpendicular to the rotation axis M1. This circle will pass through at least a part of the driving part 180h and at least a part of the first braking engagement member 204 at the same time.

[0125] Continue to refer to Figure 2A-2D The second braking coupling member 208 has an inner protrusion 208e protruding toward the rotation axis M1. Further, along the rotation direction r of the force output member 203, the first braking coupling member 204 has an outer output surface 204g located downstream of the first braking coupling member body 204z, and the second braking coupling member 208 has an inner output surface 208f located downstream of the second braking coupling member body 208z. The inner protrusion 208e protrudes radially inward / towards the rotation axis M1 from the second braking coupling member body 208z. Along the rotation direction r, the inner protrusion 208e has a downstream plane 208g, which is adjacent to the inner output surface 208f. Further, as... Figure 2BAs shown, along the rotation axis M1, the drive unit 180h has a drive end surface 180y at the end, the first brake coupling member 204 has a first brake end surface 204y at the end, and the second brake coupling member 208 has a second brake end surface 208y at the end. The end refers to the end of the drive unit 180h, the first brake coupling member 204, and the second brake coupling member 208 that is furthest from the flange portion 180a.

[0126] When the drive unit 180h and the brake unit 203a approach each other, the drive unit 180h and the brake unit 203a do not come into full contact with each other, such as Figure 2D As shown, along the rotation direction r, a gap is formed between the first braking end surface 204y and the driving part 180h, and the minimum value of this gap is s, that is, the closest distance between the first braking end surface 204y and the driving part 180h is s.

[0127] like Figure 2C As shown, the drive units 180h are arranged in two opposite directions along the radial direction of the drive force output member 180. The drive force output member 180 also includes a connector 180k connecting the two drive units. The connector 180k includes an intermediate member 183 and a first connector 181 and a second connector 182 located on the radial sides of the intermediate plate 183, respectively. The positioning boss 180i protrudes from the intermediate plate 183 along the rotation axis M1. The first connector 181 and the second connector 182 have the same structure and are connected to one drive unit, respectively.

[0128] Furthermore, the drive unit 180h has a lower protrusion 180g on its side surface (drive force output surface) 180d facing the first brake coupling member 204. Along the rotation direction r, the drive unit 180h also has an inclined surface 180j adjacent to the drive force output surface 180d. The first brake coupling member 204 has an upper protrusion 204f on its side surface facing the drive unit 180h. Before the processing box 100 is installed, the drive unit 180h and the first brake coupling member 204 approach each other along the rotation direction r. Along the rotation axis M1, the upper protrusion 204f and the lower protrusion 180g are opposite to each other / overlap.

[0129] Overall, the lower protrusion 180g is integrally formed with the first connector 181. The driving force output surface 180d protrudes from the lower protrusion 180g along the rotation axis M1. Along the rotation direction r, the lower protrusion 180g can also be regarded as protruding from the first connector 181 / driving force output surface 180d. The end of the lower protrusion 180g is formed as a front surface 180g1 that can rotate with the drive part 180h. Furthermore, along the rotation direction r, the first connector 181 also has a sub-front surface 180g2 located downstream in the rotation direction. The front surface 180g1 and the sub-front surface 180g2 are connected, and both the front surface 180g1 and the sub-front surface 180g2 are located at the downstream end of the first connector 181. Therefore, the front surface 180g1 and the sub-front surface 180g2 can be collectively referred to as the downstream end surface of the first connector 181.

[0130] Along the rotation direction r, the force output member 203 has a first space K1, a second space K2, and a third space K3. The first space K1 refers to the space between the front surface 180g1 and the braking part 203a. The second space K2 refers to the space between the braking part 203a and the driving part 180h located downstream of the braking part. Specifically, as shown... Figure 2D As shown, the second space K2 refers to the space between the first braking force output section 203a and the second driving force output section 180m, or the space between the second braking force output section 203b and the first driving force output section 180h. The third space K3 refers to the space between the driving section 180h / driving force output surface 180d and the first braking engagement member 204. When the driving section 180h and the braking section 203a partially overlap, as shown... Figure 2D As shown, along the rotation direction r, the second space K2 is greater than the first space K1 / the third space K3.

[0131] like Figure 4A As shown, the driving force receiving member 4 of the present invention has a rotation axis L21 and includes a connecting part 41, a chassis 42, a base 43, and a connecting part 44. Along the rotation axis L21, the connecting part 41, chassis 42, base 43, and connecting part 44 are arranged in sequence. The connecting part 41 is directly or indirectly connected to the rotating member and is used to transmit driving force to the rotating member to drive the rotating member to rotate. The chassis 42 abuts against the rotating member, so that the driving force receiving member 4 is positioned relative to the rotating member. The base 43 extends from the chassis 42, and the base 43 and the connecting part 41 are respectively located on both sides of the chassis 42. The connecting part 44 extends from the base 43 in a direction away from the chassis 42. As a simplified structure, the chassis 42 can be omitted, and the base 43 extends directly from the connecting part 41. In a more simplified case, the base 43 can also be omitted, and the connecting part 44 extends from the connecting part 41.

[0132] The structure of the joint 44 will be described below, and other structures of the driving force receiver 4 are not limited here. To more clearly illustrate the structure of the driving force receiver of the present invention, only the driving force receiver 4 is shown below. However, it should be understood that the driving force receiver 4 can be applied to various rotating parts in the processing box. According to the actual needs of the product, those skilled in the art can combine the following embodiments and their variations.

[0133] [Drive force receiver]

[0134] [Example 1]

[0135] Figure 4A This is a perspective view of the photosensitive drum of the driving force receiving device according to Embodiment 1 of the present invention; Figure 4B This is a perspective view of the first type of driving force receiving device according to Embodiment 1 of the present invention; Figure 4C This is a side view of the first type of driving force receiving device according to Embodiment 1 of the present invention when viewed along its rotation axis.

[0136] The photosensitive drum 21 has a rotation axis L21, and the driving force receiver 4 includes a connecting part 41 (such as...). Figure 4B As shown), the drive force receiver 4 is connected to the photosensitive drum 21 by embedding the drive force receiver 4 inside the photosensitive drum 21. The chassis 42 abuts against the photosensitive drum 21, so that the drive force receiver 4 is positioned relative to the photosensitive drum 21. The base 43 extends from the chassis 42, and the joint 44 extends from the base 43 in a direction away from the chassis 42. As a simplified structure, the chassis 42 can be omitted, and the base 43 extends directly from the joint 41. In a more simplified case, the base 43 can also be omitted, and the joint 44 extends from the joint 41.

[0137] The structure of the joint 44 will be described below, and other structures of the driving force receiving member 4 are not limited here.

[0138] The connecting part 44 includes a central post 45 and a driving force receiving part 46 extending radially outward from the central post 45. The rotation axis L21 passes through the central post 45, and the two driving force receiving parts 46 are arranged radially opposite to each other on the periphery of the central post 45. Figure 4A and Figure 4B As shown, each drive force receiving part 46 includes a base 461 connected to a central post 45 and a protrusion 462 located radially outside the base 461. Along the radial direction of the drive force receiving member 4, the protrusion 462 is located radially outside the base 461, and a guide surface 463 extends from the base 461 toward the protrusion 462. The protrusion 462 has a first surface / drive surface 464 and a second surface / brake surface 465 adjacent to the guide surface 463, and both the first surface 464 and the second surface 465 are parallel to the rotation axis L21.

[0139] As the processing box C is installed toward the device, the guide surface 463 guides the braking part 203a to move relative to the driving part 180h, so that the driving force receiving part 46 reaches between the driving part 180h and the braking part 203a, that is, the driving force receiving part 46 enters the third space K3, as... Figure 4C As shown, the driving force output surface 180d abuts against the first surface 464, and the second surface 465 is spaced apart from the braking part 203a. When the driving part 180h rotates in the rotation direction r, the driving force is transmitted to the joint part 44 through the first surface 464, and then the photosensitive drum 21 is driven to rotate around the rotation axis L21.

[0140] Since the second surface 465 and the braking part 203a are spaced apart, that is, when the driving force receiver 4 stops working, it no longer needs to be braked. During the process of the processing box C returning from the working state to the non-working state or the process of the photosensitive drum 21 returning from the rotating state to the non-rotating state, the braking part 203a does not apply force / braking force to the driving force receiver 4 along the circumferential direction of the photosensitive drum 21. It is equivalent to the braking part 203a being shielded, which helps to reduce the wear of the driving force receiver 4 during operation. Furthermore, after adopting the driving force receiver 4 involved in this embodiment, the braking part 203a in the device no longer needs to return to the position that is close to or partially overlaps with the driving part 180h, which helps to simplify the structure of the device. For the driving part 180h and the braking part 203a that are already in a separated state, the driving force receiver 4 of the next processing box does not need to be provided with the guide surface 463, and the structure of the processing box C can also be simplified.

[0141] [Example 2]

[0142] Figure 5A This is a perspective view of the driving force receiving device according to Embodiment 2 of the present invention; Figure 5B This is a side view of the driving force receiving device according to Embodiment 2 of the present invention when viewed along its rotation axis.

[0143] For ease of understanding, structures identical to the first type of driving force receiver 4 described above will be designated with the same numbering.

[0144] The structure of the driving force receiving unit 46 in this embodiment differs from that in Embodiment 1. For example... Figure 5A As shown, in this embodiment, the driving force receiving part 46 is simplified to at least one independent protrusion 462, which also has a first surface 464 and a second surface 465 opposite each other. Along the rotation direction r, the first surface 464 is located upstream of the second surface 465. When the processing box C is installed in the predetermined position of the device, the first surface 464 reaches the downstream space K2 (second space K2) of the braking part 203a. At this time, the first surface 464 is opposite to the braking part 203a.

[0145] When the processing box C starts working, the braking part 203a rotates together with the driving part 180h. At this time, the braking part 203a abuts against the first surface 464 and drives the driving force receiving member 4 to rotate in the rotation direction r. Similar to Embodiment 1, the driving force receiving member 4 in this embodiment does not need to be braked by the braking part when it stops working, which helps to reduce the wear of the driving force receiving member 4 during operation. During the process of the processing box C returning from the working state to the non-working state or the process of the photosensitive drum 21 returning from the rotating state to the non-rotating state, the driving part 180h does not apply force / braking force to the driving force receiving member along the circumferential direction of the photosensitive drum 21, which is equivalent to the driving part 180h being shielded.

[0146] In this embodiment, the structure of the driving force receiver 4 is simplified, and the contact surface between the driving force receiver 46 and the force output member 203 is increased, which improves the bonding stability of the driving force receiver 46 and the force output member 203 and the force stability of the driving force receiver 46, making it less likely for the driving force receiver 46 and the force output member 203 to detach.

[0147] On the other hand, since the second space K2 is the largest, the driving force receiving part 46 is more likely to enter the second space K2 than the driving force receiving part 46 enters the first space K1 or the third space K3. Therefore, the scheme of using the braking part 203a to drive the driving force receiving part 4 can also improve the connection efficiency between the driving force receiving part 4 and the force output part 203 and prevent misalignment between the driving force receiving part 4 and the force output part 203.

[0148] [Example 3]

[0149] Figure 6 This is a perspective view of the driving force receiving device according to Embodiment 3 of the present invention.

[0150] In this embodiment, the aforementioned braking surface 465 is eliminated. As shown in the figure, the driving force receiving part 46 is only provided with a driving surface 464 and a guide surface 463. The guide surface 463 extends spirally upward from the base 43. After the processing box C with the driving force receiving part 46 / driving force receiving element 4 is installed in the imaging device, the guide surface 463 can also be opposite to the coupling engagement portion 204b / 208b of the braking part 203a and play the same role as the braking surface 465. Therefore, the structure of the driving force receiving part 46 is simplified, which is beneficial to improving the production efficiency of the driving force receiving part 46 and the driving force receiving element 4 with the driving force receiving part 46.

[0151] Furthermore, the driving force receiving part 46 also includes a flange part 47, which is disposed along the outer circumference of the central post 45. In other words, the flange part 47 protrudes radially outward from the outer circumferential surface of the central post 45. Preferably, along the rotation axis L21, the flange part 47 is located at the free end 451 of the central post 45 (the end away from the connecting part 41). When viewed along a direction perpendicular to the rotation axis L21, the driving force receiving part 46 and the flange part 47 do not coincide. Along the radial direction of the driving force receiving member 4, the protrusion of the flange part 47 is... The dimensions of the base 461 / driving surface 464 / guide surface 463 do not exceed the size of the base 461 / driving surface 464 / guide surface 463. During the process of engaging the driving force receiving member 4 with the force output member 203, the coupling engagement portion 204b / 208b of the braking part 203a hooks onto the flange portion 47 to achieve the engagement of the driving force receiving member 4 and the force output member 203. This can effectively prevent the driving surface 464 of the driving force receiving member 4 from disengaging from the driving force output surface 180d of the force output member 203, thereby ensuring that the driving force receiving member 4 can stably receive driving force from the force output member.

[0152] [Example 4]

[0153] Figure 7 This is an exploded view of the driving force receiving device according to Embodiment 4 of the present invention; Figure 8A This is a perspective view of the starting point of the connection between the driving force receiving component and the force output component according to Embodiment 4 of the present invention; Figure 8B This is a perspective view of the combined driving force receiving component and force output component according to Embodiment 4 of the present invention; Figure 8C This is a side view of the driving force receiver and the force output device after they are combined, viewed in a direction perpendicular to the rotation axis of the driving force receiver, according to Embodiment 4 of the present invention.

[0154] In this embodiment, the connecting portion 44 is configured to move relative to the second rotating member / photosensitive drum 21 or the connecting portion 41 along the rotation axis L21. That is, the connecting portion 44 can move between a position close to the connecting portion 41 (connecting portion retracted state) and a position far from the connecting portion 41 (connecting portion extended state).

[0155] As shown in the figure, the connecting part 44 is separately formed from the base 43. The driving force receiving member 4 also includes an active cavity 432 formed inside the base 43 and a retaining member 49 for holding the connecting part 44 away from the second rotating member / photosensitive drum 21 or the connecting part 41. The retaining member 49 is preferably a compression spring. At this time, the driving force receiving member 4 can be decomposed into a connected part 4z including the connecting part 41, the chassis 42 and the base 43, a connecting part 44 separately formed from the connected part 4z, and a retaining member 49 located between the connected part and the connecting part. The connected part 4z is used to transmit the driving force received by the connecting part 44, and the retaining member 49 is used to push the connecting part 44 away from the connected part 4z along the rotation axis L21. The connecting part 44 includes a base plate 441, a central column 45 extending from one side of the base plate 441 and a driving force receiving part 46, and a driving force transmitting part 442 extending from the other side of the base plate 441. Along the rotation axis L21, the central column 45 and the driving force receiving part 46 extend away from the connecting part 41, and the driving force transmitting part 442 extends towards the connecting part 41.

[0156] The driving force receiving unit 46 still has a guide surface 463 and a driving surface 464. During the engagement of the driving force receiving member 4 and the force output member 203, the guide surface 463 is used to force the braking member 203a to rotate relative to the driving member 180h, thereby separating the braking member 203a and the driving member 180h from each other. The driving surface 464 is used to receive the driving force. In this embodiment, the driving force receiving unit 46 does not have a braking surface for receiving braking force.

[0157] The driving force transmission part 442 is used to engage with the base 43 to transmit the driving force received by the driving force receiving part 46 to the base 43, thereby driving the rotating member 21 connected to the connecting part 41 to rotate. In some embodiments, the driving force transmission part 442 is configured as a protrusion extending from the base plate 441 toward the connecting part 41 along the rotation axis L21. Correspondingly, the side wall of the movable cavity 432 is provided with a groove 433 that can cooperate with the protrusion, or the positions of the protrusion and the groove are interchanged. The base plate 42 is formed as the bottom wall of the movable cavity 432. One end of the compression spring 49 abuts against the base plate 42, and the other end abuts against the side surface of the base plate 441 facing the connecting part 41.

[0158] Furthermore, the connecting part 44 also includes a guide connecting post 443 disposed on the same side as the driving force transmission part 442. Correspondingly, the chassis 42 is provided with a guide hole 421 that cooperates with the guide connecting post 443. The guide connecting post 443 is configured as a cantilever that can elastically deform in the direction intersecting with the rotation axis L21. The end of the cantilever is provided with a snap-fit ​​protrusion 444. During the installation of the connecting part 44, the guide connecting post 443 is squeezed and undergoes elastic deformation, and the snap-fit ​​protrusion 444 snaps into the guide hole 421. The connecting part 44 and the connecting part 41 / base 43 can achieve a stable connection. During the movement of the connecting part 44 along the rotation axis L21, the cooperation between the guide connecting post 443 and the guide hole 421 can ensure that the movement trajectory of the connecting part 44 does not deviate.

[0159] When the driving force receiver 4 is combined with the force output member 203, the guide surface 463 forces the braking part 203a to rotate in the rotation direction r and separate it from the driving part 180h. Subsequently, the driving surface 464 faces the driving force output surface 180d, and the driving force receiver 4 and the force output member 203 are combined. The driving force receiver 4 can then receive the driving force output by the driving part 180h.

[0160] In this embodiment, the braking part 203a is gradually retracted towards the retracted state while being pushed and guided by the guide surface 463. When the driving surface 464 is opposite to the driving force output surface 180d, the braking part 203a can be in a state of being pressed by the guide surface 463 or in an extended state of no longer being pressed by the guide surface 463. Regardless of the state of the braking part 203a, it will not affect the driving force output surface 180d from outputting driving force to the driving surface 464. At this time, the braking part 203a will not apply braking force to the driving force receiving member 4 and can be regarded as being shielded.

[0161] Unlike the above embodiments, the connecting part 44 in this embodiment is designed to be retractable. During the connection process between the driving force receiving member 4 and the force output member 203, the braking part 203a is pressed by the guide surface 463, and conversely, the guide surface 463 is also pressed by the braking part 203a. The connecting part 44 will retract towards the connecting part 41 / photosensitive drum 21, and the compression spring 49 will also undergo elastic deformation. In this way, the driving force receiving part 46 will be pushed towards the force output member 203 by the compression spring 49. That is to say, the driving force receiving part 46 can follow the movement of the driving part 180h / braking part 203a. Finally, the driving force receiving member 4 and the force output member 203 can also maintain a stable and tight connection.

[0162] [Example 5]

[0163] Figure 9A This is a perspective view of the driving force receiving device according to Embodiment 5 of the present invention; Figure 9BThis is a side view taken along the rotation axis of the driving force receiving device according to Embodiment 5 of the present invention; Figure 10 This is a perspective view of the combined driving force receiving component and force output component according to Embodiment 5 of the present invention; Figure 11 The driving force receiving component and the force output component involved in Embodiment 5 of the present invention are combined, and then... Figure 10 A sectional view cut along the AA direction.

[0164] Based on the structure of the force output member 203, the driving force receiving member 4 in this embodiment is configured such that when the driving force receiving member 4 is combined with the force output member 203, the driving force receiving member 4 is combined with the front surface 180g1 of the driving part 180h.

[0165] like Figure 9A and Figure 9B As shown, the driving force receiving part 46 includes a base 461 and a protrusion 462 located radially outside the central post 45. The protrusion 462 is further away from the rotation axis L21 than the base 461. The protrusion 462 forms a strip-shaped body extending along the rotation axis L21 and is still provided with a guide surface 463 and a driving surface 464. The guide surface 463 is configured as an inclined surface or a spiral surface that is inclined relative to the rotation axis L21. The driving surface 464 is disposed adjacent to the guide surface 463 and can match the front surface 180g1.

[0166] like Figure 10 As shown, when the driving force receiving member 4 is combined with the force output member 203, the guiding surface 463 enters between the driving part 180h / driving force output surface 180d and the braking part 203a under the guidance of the inclined surface 180j, and the driving surface 464 is opposite to the front surface 180g1. As the force output member 203 rotates, the driving force is transmitted to the driving surface 464 through the front surface 180g1. Preferably, the front surface 180g1 and the driving surface 464 are both set to be parallel to the rotation axis L21 / M1.

[0167] Furthermore, the driving force receiving part 46 also includes a reinforcing part 46e. Along the rotation direction r, the protrusion 462 and the reinforcing part 46e are spaced apart. The protrusion 462 is used to receive driving force and can be referred to as the driven part 46d. The reinforcing part 46e is used to enhance the strength of the driving force receiving member 4, prevent the driving force receiving member 4 from being broken during the process of receiving driving force, and also prevent the driving force receiving member 4 from being tumbled and broken by an external collision before it is combined with the force output member 203.

[0168] like Figure 11As shown, when the driving force receiving member 4 is combined with the force output member 203, the front surface 180g1 of the first connecting member 181 abuts against the driven part 46d, and the reinforcing part 46e abuts against the second connecting member 182. This not only ensures a stable connection between the driven part 46d and the front surface 180g1, but also serves to position the driven part 46d.

[0169] In the modified version of this embodiment, the following continues... Figure 11 As shown, the driving surface 464 can also be configured to receive driving force by abutting against the front surface 180g2. Along the rotation direction r, the front surface 180g2 is opposite to and separated from the first braking engagement member 204. When the driving surface 464 abuts against the front surface 180g2, the protrusion 462 will not contact the first braking engagement member 204. It can be seen that in this modified mode, it is not necessary to separate the driving part 180h from the braking part 203a so that the driving part 180h can output driving force to the protrusion 462.

[0170] [Example 6]

[0171] Figure 12A This is an exploded view of the driving force receiving device according to Embodiment Six of the present invention; Figure 12B This is an exploded view of the driving force receiving component after it is separated from the second unit housing in a modified embodiment of Embodiment Six of the present invention; Figure 12C It is along Figure 12B Cross-sectional view after cutting along the DD direction; Figure 13A This is a perspective view of the driving force receiving device according to Embodiment Six of the present invention; Figure 13B This is a side view taken along the rotation axis of the driving force receiving device according to Embodiment Six of the present invention; Figure 14A and Figure 14B This is a state diagram of the driving force receiving device and the force output device after being combined according to Embodiment Six of the present invention.

[0172] Similar to Embodiment 5, in this embodiment, the driving force receiver 4 is configured such that when the driving force receiver 4 is combined with the force output member 203, the driving force receiver 4 is combined with the front surface 180g1 of the driving part 180h.

[0173] If the driving force receiver 4 and the force output unit 203 are connected in the manner described in the above embodiment, where the braking part 203a outputs driving force to the driving force receiver 4, the imaging device will produce unacceptable noise in actual testing. According to preliminary analysis, the noise is caused by the collision between the driving part 180h and the braking part 203a, which are close to each other, or by the contact between the component of the force output unit 203 and the inner wall of the imaging device, or by the braking part 203a retracting into the cylindrical part 180c.

[0174] Therefore, this embodiment provides a driving force receiver 4 that can eliminate the aforementioned noise. For example... Figure 12A As shown, the driving force receiver 4 includes a connecting part 41, a chassis 42, a main body 4x, and an auxiliary part 4y. The main body 4x is connected to the connecting part 41 or the chassis 42. The auxiliary part 4y is configured to rotate relative to the main body 4x / processing box housing / photosensitive drum 21. At least a portion of the auxiliary part 4y and the connecting part 41 are located on opposite sides of the chassis 42. Specifically, the main body 4x includes a base 43 connected to the connecting part 41 or the chassis 42 and a connecting part 44 disposed on the base 43. The connecting part 44 includes a central column 45 and a driving force receiving part 46 extending radially outward along the central column 45. The rotation axis L21 passes through the central column 45. The driving force receiving part 46 includes a base 461 and a protrusion 462. Along the radial direction of the driving force receiving part 4 / connecting part 44, the protrusion 462 is located radially outside the base 461. As described above, the connecting part 44 also includes a base plate 441. The central column 45 extends from one side of the base plate 441 along the direction of the rotation axis L21. The connecting part 44 is connected to the base 43 through the base plate 441. In this embodiment, at least a portion of the base plate 441 can be regarded as the base 461.

[0175] The protrusion 462 is configured as a columnar body extending along the rotation axis L21, and a driving surface 464 for receiving driving force is provided on the protrusion 462. Preferably, the main body 4x is integrally formed with the connecting part 41 and the chassis 42, and the base 43 and the connecting part 44 are also integrally formed. The protrusion 462 also has a fourth surface 4621. Along the rotation axis L21, the fourth surface 4621 is the surface of the protrusion 462 furthest from the connecting part 41. Along the rotation axis L21, when the protrusion 462 extends beyond the central column 45, the fourth surface 4621 is the end surface 4w of the driving force receiving member 4. Preferably, the fourth surface 4621 is a plane, and more preferably, the fourth surface 4621 is a plane perpendicular to the rotation axis L21.

[0176] The driving force receiving member 4 also includes a main body 4x with a driving force receiving portion 46, at least a portion of which is accommodated by an auxiliary member 4y. The auxiliary member 4y has a limiting portion 4y4, and the main body 4x has a limiting portion 434 for engaging with the limiting portion 4y4. Specifically, the auxiliary member 4y includes a carrier 4y1, a separating member 4y2 protruding from the carrier 4y1, and a limiting portion 4y4 disposed on the carrier 4y1 or the separating member 4y2. In some embodiments, the auxiliary member 4y / carrier 4y1 is sleeved on the outside of the main body 4x, and the main body 4x also has a limiting portion 434 for engaging with the limiting portion 4y4. Through the engagement of the limiting portion 4y4 and the limiting portion 434, the auxiliary member 4y is restricted along the rotation axis L21, and is not restricted along the rotation direction r. In some embodiments, the carrier 4y1 is configured as an annular body with an internally formed receiving cavity 4y6, at least a portion of the main body 4x is received by the receiving cavity 4y6, and the limiting portion 4y4 is configured as a locking protrusion protruding radially from the annular body 4y1 toward the receiving cavity 4y6. The limiting portion 434 is a locking groove provided on the outer surface of the base 43 or the connecting portion 44, and the locking groove 434 extends in the rotation direction r. Conversely, the locking groove can also be provided on the annular body 4y1, and the locking protrusion 4y4 can also be provided on the base 43 or the connecting portion 44. The locking protrusion can extend a full circle in the rotation direction r, or it can only extend a predetermined angle in the rotation direction r.

[0177] In some embodiments, to facilitate the engagement of the engagement protrusion 4y4 and the engagement groove 434, the auxiliary member 4y is also provided with an elastic arm 4y3 connected to the ring body 4y1. The engagement protrusion 4y4 / engagement groove 434 is provided on the elastic arm 4y3. The elastic arm 4y3 can elastically deform relative to the ring body 4y1, thereby achieving a convenient engagement between the auxiliary member 4y and the main body 4x. Preferably, the elastic arm 4y3 is integrally formed with the main body 4y1, and a gap is formed between the elastic arm 4y3 and the main body 4y1 to allow the elastic arm 4y3 to elastically deform relative to the main body 4y1. More preferably, when the elastic arm 4y3 is provided, the engagement part 4y4 / engaged part 434 is only provided on the elastic arm 4y3, which is more conducive to the convenient engagement between the auxiliary member 4y and the main body 4x.

[0178] In some embodiments, the auxiliary component 4y can also be sleeved on the housing of the processing box. Similarly, the limited portion 4y4 can be provided on the auxiliary component 4y, and a limiting portion for limiting the limited portion 4y4 can be provided on the housing, as long as it is ensured that the auxiliary component 4y can rotate about a direction parallel to the rotation axis L21 and that the auxiliary component 4y will not detach from the housing. For example, the limitation of the auxiliary component 4y can be achieved by the housing abutting against the end face of the auxiliary component 4y. Based on this inventive concept, the auxiliary component 4y has a variety of installation positions. For example, the auxiliary component 4y can be sleeved on at least one of the charging component, the supply component, and the stirring component.

[0179] Specifically, such as Figure 12B and Figure 12C As shown, the main body 4y1 still has an elastic arm 4y3, which has a locking part 4y4. The housing / second unit housing 2 includes a support member 25 and a limiting part 434 disposed in the support member 25. As shown, the auxiliary member 4y is rotatably supported by the support member 25. Along the rotation axis L21, the locking part 4y4 abuts against the limiting part 434. Therefore, the auxiliary member 4y is restricted in the direction of the rotation axis L21, but not in the rotation direction r. Furthermore, the auxiliary member 4y is sleeved on the outside of the main body 4x, or in other words, the main body 4x enters the receiving cavity 4y6, and the auxiliary member 4y can rotate around the main body 4x.

[0180] In some embodiments, the auxiliary component 4y can also be rotatably installed in a pre-set positioning groove in the housing or main body 4x. In this structure, it is not necessary to set up a component to support the auxiliary component 4y in the positioning groove. The positioning of the auxiliary component 4y can be achieved by using the inner wall of the positioning groove. Thus, the carrier 4y1 can also be set as a solid, as long as the carrier 4y1 can rotate relative to the housing / photosensitive drum 21.

[0181] Preferably, when the auxiliary member 4y is coaxially arranged with the main body 4x, the separating member 4y2 and the protrusion 462 are spaced apart from each other along the radial direction of the driving force receiving member 4, so that the auxiliary member 4y with the separating member 4y2 can rotate freely around the rotation axis L21.

[0182] Furthermore, the separating member 4y2 is provided with a guide surface 463 and a barb surface 46f. Along the rotation axis L21, the separating member 4y2 has a tip portion 4y22 furthest from the connecting portion 41. The guide surface 463 is used to guide the separating member 4y2 to a predetermined position. The barb surface 46f is set to be inclined relative to the rotation axis L21, and the inclination direction of the barb surface 465 is such that when viewed along a direction perpendicular to the rotation axis L21, the barb surface 46f faces the connecting portion 41. Therefore, the barb surface 46f can prevent the braking portion 203a from moving towards the flange portion 180a, that is, the barb surface 46f can prevent the force output member 203 from separating from the driving force receiving member 4.

[0183] At least a portion of the auxiliary member 4y is used to separate the drive part 180h and the brake part 203a in the rotational direction of the force output member 203. During the movement of the drive force receiving member 4 toward the force output member 203, at least a portion of the auxiliary member 4y enters the space between the drive part 180h and the brake part 203a, and the guide surface 463 abuts against the brake part 203a, forcing the brake part 203a away from the drive part 180h in the rotational direction r. Subsequently, in the rotational direction r, the separating member 4y2 enters the third space K3 between the drive part 180h and the brake part 203a, and the separating member 4y2 is opposite to the drive force output surface 180d. At the same time, the protrusion 462 reaches the downstream of the front surface 180g1 and is located in the first space K1, the front surface 180g1 is opposite to the drive surface 464, and the drive force receiving part 46 is engaged with the drive part 180h.

[0184] When the force output member 203 starts to rotate, the driving force output by the drive unit 180h is transmitted to the drive force receiving member 4 through the contact between the front surface 180g1 and the drive surface 464. The barb surface 46f is combined with the brake part 203a. Since the barb surface 46f is set as an inclined surface as described above, the brake part 203a is "hooked" by the barb surface 46f and will not move towards the flange part 180a along the rotation axis L21. The barb surface 46f can also be regarded as an embodiment of the anti-detachment part.

[0185] The driving part 180 and the braking part 203a are separated by the separating member 4y2, or in other words, at least a part of the separating member 4y2 enters the third space K3. When the driving force receiving member 4 in this embodiment receives the driving force output by the force output member 203, the noise emitted by the imaging device is eliminated. Accordingly, as long as the separating member 4y2 can enter the third space K3, so that the driving part 180h and the braking part 203a are separated from each other in the rotation direction r, the barb surface 46f does not need to be provided.

[0186] As described above, in this embodiment, the separator 4y2 is configured to become movable as the carrier 4y1 rotates relative to the housing / photosensitive drum 21. Therefore, during the installation and removal of the processing box C, the movable carrier 4y1 / separator 4y2 improves the installation and removal flexibility of the processing box C and reduces the risk of interference between the processing box C and the imaging device.

[0187] [Example 7]

[0188] Figure 15 This is a perspective view of the driving force receiving device according to Embodiment 7 of the present invention; Figure 16 This is a state diagram of the driving force receiving device and the force output device after being combined according to Embodiment 7 of the present invention.

[0189] The difference between this embodiment and embodiment six is ​​that in this embodiment, the driving force receiving member 4 does not abut against the front surface 180g1 to receive the driving force, but abuts against at least one of the outer output surface 204g and the inner output surface 208f of the braking part 203a to receive the driving force.

[0190] The protrusion 462 is provided with a driving surface 464 that can match at least one of the external output surface 204g and the internal output surface 208f. Both the external output surface 204g and the internal output surface 208f extend spirally relative to the rotation axis L21, and their extension direction is opposite to the rotation direction r. Figure 16 As shown, when the driving surface 464 engages with the inner output surface 208f, as the force output member 203 rotates in the rotation direction r, the driving surface 464 receives the driving force from the first braking engagement member 204. However, the protrusion 462 also applies a reaction force to the first braking engagement member 204 toward the flange portion 180a. This reaction force causes the second braking engagement member 208 to tend to move toward the flange portion 180a. Therefore, there is a risk that the driving surface 464 and the inner output surface 208f will disengage from each other.

[0191] However, when the barbed surface 46f provided in the separator 4y2 is engaged with the braking part 203a, the braking part 203a tends to be pulled away from the flange part 180a or towards the connecting part 41. The tendency of the braking part 203a to move towards the flange part 180a is stopped. In this way, the driving surface 464 and the inner output surface 208f can achieve a stable engagement.

[0192] As described above, in this embodiment, the driving surface 464 is engaged with the inner output surface 208f. However, in some embodiments, the driving surface 464 can also be engaged with the outer output surface 204g. For example, the auxiliary member 4y is rotatably mounted in a receiving groove provided in the base 43. Along the radial direction of the driving force receiving member 4, the receiving groove is located radially inside the protrusion 462. During the engagement of the driving force receiving member 4 and the force output member 203, the separating member 4y2 enters between the driving part 180h and the braking part 203a, separating the driving part 180h and the braking part 203a from each other along the rotation direction r, and the protrusion 462 reaches the second space K2. In general, at least a portion of the auxiliary member 4y enters the space between the driving part 180h and the braking part 203a, and the driving force receiving part 46 is engaged with the braking part 203a.

[0193] [Example 8]

[0194] Figure 17 This is a perspective view of the driving force receiving device according to Embodiment 8 of the present invention; Figures 18A-18D This is a schematic diagram of the combination process of the driving force receiving device and the force output device involved in Embodiment 8 of the present invention.

[0195] Based on Embodiments 6 and 7, this embodiment further optimizes the structure of the auxiliary component 4y.

[0196] As described above, the auxiliary component 4y is configured to rotate freely relative to the main body 4x about the rotation axis L21. Before the driving force receiving component 4 and the force output component 203 are combined, the stopping position of the auxiliary component 4y relative to the main body 4x along the rotation direction r will be random. That is to say, the position of the separating component 4y2 relative to the main body 4x is uncertain.

[0197] In order to ensure that the separating member 4y2 can accurately enter the space between the driving part 180h / driving force output surface 180d and the braking part 203a (third space K3), the driving force receiving member 4 in this embodiment adopts the following scheme.

[0198] The auxiliary component 4y also includes at least one auxiliary protrusion 4y5 protruding from the ring body 4y1. The auxiliary protrusion 4y5 assists the separating component 4y2 and / or the driving surface 464 in reaching a predetermined position. Specifically, along the rotation direction r, the separating component 4y2 enters the third space K3, and the protrusion 462 with the driving surface 464 enters the second space K2. The driving surface 464 is opposite to at least one of the outer output surface 204g and the inner output surface 208f. When multiple auxiliary protrusions 4y5 are provided, preferably, four auxiliary protrusions 4y5 are spaced apart along the circumferential direction of the auxiliary component 4y; more preferably, the four auxiliary protrusions 4y5 are distributed at equal intervals along the circumferential direction of the auxiliary component 4y.

[0199] like Figure 18A As shown, when the driving force receiving member 4 approaches the force output member 203 along the rotation axis L21 / M1, the separating member 4y2 is not opposite to the third space K3 along the direction of the rotation axis L21 / M1, and the separating member 4y2 deviates to be opposite to the second space K2; as the driving force receiving member 4 continues to move, as Figure 18B As shown, the auxiliary protrusion 4y5 abuts against the drive unit 180h and / or the brake unit 203a. When the processing box C reaches the installation position, the auxiliary protrusion 4y5 still abuts against the drive unit 180h and / or the brake unit 203a.

[0200] like Figure 18C As shown, when the force output member 203 begins to rotate in the rotation direction r, the separating member 4y2 begins to abut against the downstream surface (outer output surface 204g and inner output surface 208f) of the braking part 203a. As the force output member 203 continues to rotate, the braking part 203a is pressed by the separating member 4y2 and moves towards the flange portion 180a (towards the interior of the cylindrical portion 180c) until the braking part 203a passes the tip portion 4y22 of the separating member 4y2; subsequently, the braking part 203a begins to abut against the guide surface 463, as... Figure 18D As shown, the separating member 4y2 enters the third space, and along the rotation direction r, the braking part 203a gradually moves away from the driving part 180h.

[0201] Similarly, as the driving force receiving member 4 approaches the force output member 203, along the rotation axis L21 / M1, regardless of whether the protrusion 462 is directly opposite the second space K2, or opposite the downstream surface 204g / 208f of the braking part 203a, or opposite the first braking end surface 204y and / or the second braking end surface 208y, or opposite the driving part 180h, as long as the force output member 203 starts to rotate in the rotation direction r, the protrusion 462 can directly enter the second space K2, or enter the second space K2 by pressing the force output member 203, and the driving surface 464 can eventually abut against the downstream surface of the braking part 203a.

[0202] When the driving force receiver 4 is configured such that the driving surface 464 abuts against the external output surface 204g to receive the driving force, in an extreme case, as the driving force receiver 4 approaches the force output component 203, along the rotation axis L21 / M1, the protrusion 462 is exactly opposite the third space K3. To prevent the protrusion 462 from entering the third space K3, it is possible that the minimum dimension of the fourth surface 4621 is greater than the distance s along the rotation direction r. When the extreme case occurs, the fourth surface 4621 can simultaneously abut against the driving end surface 180y and the first braking end surface 204y. As the force output component 203 rotates, the protrusion 462 can still enter the second space K2.

[0203] [Example 9]

[0204] Figure 19 This is a perspective view of the driving force receiving device according to Embodiment Nine of the present invention.

[0205] Similar to the inventive concept of Embodiment 8, the auxiliary component 4y is provided with a plurality of mutually spaced separation components 4y2 along the rotation direction r. When the driving force receiving component 4 approaches the force output component 203 along the rotation axis L21 / M1, any one of the plurality of separation components 4y2 can enter the third space K3 along the rotation axis L21 / M1. After the protrusion 462 with the driving surface 464 enters the second space K2, the driving force receiving component 4 can smoothly receive the driving force output by the force output component 203, and the noise that the imaging device may emit is eliminated.

[0206] Similar to Embodiment 7, in this embodiment and Embodiment 8, after the driving force receiving member 4 is combined with the force output member 203, the braking surface 465 is combined with the braking part 203a. By utilizing the inclined surface structure of the braking surface 465, the tendency of the braking part 203a to move towards the flange part 180a is stopped, and the driving surface 464 can stably receive the driving force.

[0207] Of the plurality of separating members 4y2, except for the separating member 4y2 that enters the third space K3, the other separating members 4y2 can be regarded as the auxiliary protrusions 4y5 in Embodiment 8. Similarly, multiple separating members 4y2 that are equivalent to the auxiliary protrusions 4y5 can also be provided. The four auxiliary protrusions 4y5 are distributed at intervals along the circumferential direction of the auxiliary member 4y. Preferably, the four auxiliary protrusions 4y5 are distributed at equal intervals along the circumferential direction of the auxiliary member 4y.

[0208] Furthermore, the separating element 4y2 can also be set to five or six, and the five or six separating elements 4y2 are equally spaced along the circumferential direction of the auxiliary element 4y. When the number of separating elements 4y2 is less than four, the separating elements 4y2 may not be able to enter the third space K3, resulting in misalignment. When the number of separating elements 4y2 is more than six, the separating elements 4y2 may interfere with the force output element 203, causing the driving force receiving element 4 and the force output element 203 to not be able to combine smoothly.

[0209] [Example 10]

[0210] Figure 20 This is a perspective view of the second unit according to Embodiment 10 of the present invention after the hidden parts are shown; Figure 21 It is a cross-sectional view of the processing box having the second unit according to Embodiment 10 of the present invention, cut along a plane perpendicular to the rotation axis of the photosensitive drum.

[0211] As described above, when the driving force receiver 4 receives the driving force, it drives the photosensitive drum 21 along... Figure 21 As shown in r1, the charging component 24, which is in contact with the photosensitive drum 21, is driven by the frictional force between the surface of the photosensitive drum 21 and the surface of the charging component 24 to rotate in the direction shown in r2.

[0212] Generally, for a charging component 24 configured to contact the photosensitive drum 21 for charging, the charging component 24 includes a metal shaft 241 and an elastomer / coating layer 242 covering the outer surface of the metal shaft. Obviously, the density of the metal shaft is greater than that of the elastomer, and correspondingly, the inertia of the metal shaft is also greater than that of the elastomer. When the photosensitive drum 21 stops rotating, the charging component 24 will lose its power source, but under the action of inertia, the metal shaft will cause the charging component 24 to continue rotating. Thus, the friction between the surface of the charging component 24 and the surface of the photosensitive drum 21 may cause the photosensitive drum 21 to continue rotating as well.

[0213] In the prior art, the braking part 203a provided in the force output member 203 applies braking force to the driving force receiver 4 used to drive the photosensitive drum 21 to rotate, and the possible continued rotation of the photosensitive drum 21 can be stopped; however, the structure of the force output member 203 provided with the braking part 203a will become complicated, which not only increases the manufacturing difficulty of the imaging device and the driving force receiver 4, but also increases the control difficulty of the imaging device.

[0214] Based on the above embodiments, this embodiment provides a simple structure that can prevent the photosensitive drum 21 from continuing to rotate, such as... Figure 20 and Figure 21 As shown, the processing box C also includes a friction member 24a that is adjacent to and in contact with the charging member 24. The friction member 24a extends along the rotation axis L21. When the charging member 24 loses its power source, the friction between the friction member 24a and the charging member 24 forces the charging member 24, which continues to rotate due to inertia, to stop rotating. Therefore, the risk of the photosensitive drum 21 continuing to rotate can be eliminated.

[0215] Commonly, the friction element 24a can be set as an elastic component such as a sponge or rubber. When the charging element 24 is driven to rotate by the photosensitive drum 21, the friction element 24a will not apply excessive friction force to the charging element 24, thereby increasing the load on the charging element 24. However, when the charging element 24 is no longer driven by the photosensitive drum 21, the friction force between the friction element 24a and the charging element 24 is sufficient to force the charging element 24, which continues to rotate due to inertia, to stop rotating.

[0216] On the other hand, during the operation of the processing box C, the high-speed rotating photosensitive drum 21 causes the developer on its surface to detach from the photosensitive drum 21 under the action of centrifugal force and reach the surface of the charging component 24. The developer reaching the surface of the charging component 24 will reduce the charging efficiency of the charging component 24 to the photosensitive drum 21. The friction member 24a can also clean the surface of the charging component 24. As the charging component 24 rotates, the developer reaching the surface of the charging component 24 can be absorbed or scraped by the friction member 24a. Therefore, the charging component 24 can charge the photosensitive drum 21 efficiently.

[0218] Figure 22A This is a perspective view of the driving force receiving device according to Embodiment Eleven of the present invention; Figure 22B This is a side view viewed along a direction perpendicular to the rotation axis of the driving force receiving member according to Embodiment 11 of the present invention.

[0219] Based on the inventive concept of the above embodiments, the structure of the separator 4y2, the structure of the protrusion 462, and the structure of the flange 47 of the driving force receiving member 4 in this embodiment are different from those in the above embodiments, and will be described separately below.

[0220] In this embodiment, the protrusion 462 is provided with a driving surface 464 that can be combined with the outer output surface 204g or the inner output surface 208f of the braking part 203a. Preferably, the protrusion 462 is also provided with a sub-driving surface 464a adjacent to the driving surface 464. The sub-driving surface 464a is used to abut against the plane 208g and can receive the driving force of the plane 208g. Furthermore, the driving surface 464 can also be referred to as the main driving surface, and the sub-driving surface 464a can also be referred to as the slave driving surface.

[0221] The driving force receiving member 4 can receive driving force by abutting the braking part 203a through at least one of the main driving surface 464 and the driven surface 464a, thereby the driving force receiving member 4 can stably receive driving force.

[0222] The separating component 4y2 includes a separating component body 4y21 and a tip 4y22 that are joined together. The separating component body 4y21 is provided with the aforementioned guide surface 463 and barb surface 46f. The tip 4y22 extends from the guide surface 463 in a direction further away from the carrier 4y1. Preferably, the tip 4y22 is cone-shaped. Along the rotation direction r, the tip 4y22 is located upstream of the separating component 4y2. The guide surface 463 extends from the separating component body 4y21 to the tip 4y22. Along the rotation axis L21, the further away the tip 4y22 is from the carrier 4y1, the smaller its volume becomes. Therefore, when the driving force receiving component 4 and the force output component 203 begin to engage, the tip 4y22 can enter the third space K3 more quickly and accurately.

[0223] During the engagement of the driving force receiver 4 and the force output member 203, a portion of the flange portion 47 guides the braking portion 203a, ensuring that the braking portion 203a always reaches the upstream side of the main driving surface 464 and / or the driving surface 464a. This portion of the flange portion 47 can be considered an embodiment of a braking portion guide; specifically, the flange portion 47 is configured to extend radially outward from the outer surface of the central post 45. Preferably, two flange portions 47 are arranged radially opposite each other on the outer surface of the central post 45, forming a guide groove 472 between the two flange portions 47 along the rotation direction r, and the surface of the flange portion 47 facing the guide groove 472 is formed as a positioning guide surface 471. More preferably, along the rotation direction, the main driving surface 464 / driving surface 464a is located downstream of at least a portion of the guide groove 472 / positioning guide surface 471. In some embodiments, the brake guide 47 may not extend radially outward from the outer surface of the central post 45, but may be recessed radially inward from the outer surface of the central post 45, as long as the guide groove 472 and / or positioning guide surface 471 can be formed.

[0224] Preferred, such as Figure 22BAs shown, when the connecting part 41 or the chassis 42 is taken as a reference, along the rotation axis L21, the separating member 4y2 extends further than the protrusion 462. That is, along the rotation axis L21, the separating member 4y2 protrudes further than the main driving surface 464 / driven surface 464a. Thus, when the driving force receiving member 4 and the force output member 203 approach each other, the separating member 4y2 first enters the third space K3 to complete the separation of the driving part 180h and the braking part 203a. Then, the main driving surface 464 / driven surface 464a abuts against the corresponding position of the braking part 203a. This structure can effectively prevent the separating member 4y2 from being unable to separate the driving part 180h and the braking part 203a after the main driving surface 464 / driven surface 464a abuts against the corresponding position of the braking part 203a. Ultimately, the imaging device will produce unacceptable noise during operation.

[0225] like Figures 23A-26C As shown, before the driving force receiver 4 and the force output component 203 begin to combine, along the rotation axis L21, the tip 4y22 is opposite to the third space K3, and the protrusion 462 is opposite to the second space K2. As the driving force receiver 4 and the force output component 203 gradually approach each other, the tip 4y22 begins to enter the third space K3. Subsequently, the braking component 203a begins to be guided by the guiding surface 463. Along the rotation direction r, the driving component 180h and the braking component 203a gradually separate from each other. The outer output surface 204g and the inner output surface 208f gradually approach the main driving surface 464, and the plane 208g gradually approaches the driving surface 464a. Finally, the separating component 4y2 enters the third space K3, the protrusion 462 enters the second space K2, and the driving force receiver 4 and the force output component 203 complete their combination.

[0226] Furthermore, such as Figure 23B , Figure 23C , Figure 24B , Figure 24C , Figure 25B , Figure 25C , Figure 26B and Figure 26C As shown, when the driving force receiver 4 and the force output member 203 begin to engage, the inward protrusion 208e in the braking part 203a enters the guide groove 472 and is guided by the positioning guide surface 471. Therefore, the relative position of the main body 4x of the driving force receiver 4 and the force output member 203 is determined. It can be seen that the guide groove 472 / positioning guide surface 471 plays a role in positioning the main driving surface 464 and / or the driving surface 464a by guiding the inward protrusion 208e. Along the rotation axis L21, the closer the flange 47 is to the free end 451 of the central column, the earlier the inward protrusion 208e can be guided by the guide groove 472 / positioning guide surface 471. Therefore, the engagement of the driving force receiver 4 and the force output member 203 is smoother.

[0227] Specifically, along the rotation direction r, since the outer output surface 204g and the inner output surface 208f are both located downstream of at least a portion of the inward protrusion 208e, and the main drive surface 464 and the driven surface 464a are located downstream of at least a portion of the guide groove 472, when the inward protrusion 208e is guided by the guide groove 472 / guide positioning surface 471, along the rotation axis L21, at least a portion of the main drive surface 464 and at least a portion of the driven surface 464a will be opposite to the second space K2, and along the rotation direction r, the drive surface 464 and the driven surface 464a will be opposite to the braking part 203a. Thus, the driving force receiving member 4 and the force output member 203 can be more smoothly combined.

[0228] Before the driving force receiver 4 and the force output member 203 begin to engage, along the rotation axis L21, when the tip 4y22 is not opposite to the third space K3, the braking part 203a can determine the relative position of the driving force receiver 4 and the force output member 203 by being guided by the guide groove 472 / guide positioning surface 471 through the inward protrusion 208e. Furthermore, the protrusion 462, which is provided with the main driving surface 464 and the driven surface 464a, can also be opposite to the second space K2. As the force output member 203 rotates... When the separation part 4y2 is rotated, it can also enter the third space K3 along with the tip part 4y22. It can be seen that even if the driving force receiver 4 is not provided with the auxiliary part 4y, as long as the guide groove 472 / guide positioning surface 471 is provided, the driving force receiver 4 can be combined with the force output part 203. Without considering that the imaging device may produce unacceptable noise due to the proximity of the driving part 180h and the braking part 203a, the driving force receiver 4 can still be driven by the force output part 203 to work.

[0229] With the auxiliary component 4y provided, when the guide groove 472 / guide positioning surface 471 guides the inner protrusion 208e, so that the main driving surface 464 and the driven surface 464a are opposite to the braking part 203a, but the tip 4y22 has not yet entered the third space K3, the position of the tip 4y22 can be one of the following:

[0230] Along the rotation axis L21, the tip 4y22 is opposite to the braking part 203a. As the force output member 203 rotates, the tip 4y22 enters the third space K3 after passing the braking part 203a.

[0231] Along the rotation axis L21, the tip 4y22 is opposite to the drive part 180h. As the force output member 203 rotates, the tip 4y22 first enters the second space K2, and then enters the third space K3 after passing the braking part 203a.

[0232] [Example Twelve]

[0233] Figure 27 This is an exploded view of the driving force receiving device according to Embodiment Twelve of the present invention; Figure 28 This is a cross-sectional view of the driving force receiving member according to Embodiment Twelve of the present invention, cut along a plane passing through its axis of rotation.

[0234] As described above, during the engagement of the driving force receiver 4 and the force output component 203, when the separating component 4y2 cannot smoothly enter the third space K3, the separating component 4y2 will abut against the driving part 180h and / or the braking part 203a. To prevent the driving force receiver 4 and the force output component 203 from failing to engage smoothly due to the separation component 4y2 abutting against the driving part 180h and / or the braking part 203a exceeding the maximum deformation of the first spring 210 / second spring 211, the auxiliary component 4y / separating component 4y2 in this embodiment is configured to be movable along the rotation axis L21.

[0235] As shown in the figure, under the above-mentioned inventive concept of auxiliary member 4y, a compression spring 49 as a retaining member is disposed between auxiliary member 4y and main body 4x. Specifically, the driving force receiving member 4 includes a base 412 disposed in the connecting part 41, a first step surface 435 disposed on the base 412, an intermediate member 430 extending from the base 412 along the rotation axis L21, and a connecting part 44 connected to the intermediate member 430. The base 412 is formed as part of the main body 4x, and an auxiliary member receiving part 411 is formed between the base 41 and the inner wall of the connecting part 41 to accommodate the auxiliary member 4y. Specifically, along the radial direction of the driving force receiving member 4, the connecting part 41 surrounds at least a part of the base 412 on the outside of the base 412, and the auxiliary member receiving part 411 is located between the connecting part 41 and the base 412.

[0236] Along the radial direction of the driving force receiving member 4, the diameter of the base plate 441 of the joint is larger than the diameter of the intermediate member 430, and at least a portion of the diameter of the base 412 is larger than the diameter of the intermediate member 430. Therefore, the limiting part 434 is formed between the base plate 441 and the base 412. One end of the compression spring 49 abuts against the first step surface 435, and the other end abuts against the auxiliary member 4y / the limiting part 4y4.

[0237] When the auxiliary member 4y / separator 4y2 comes into contact with the drive unit 180h and / or the brake unit 203a, even if the first spring 210 / second spring 211 has reached its maximum deformation, the auxiliary member 4y / separator 4y2 can retract toward the connecting part 41 by compressing the compression spring 49 to undergo elastic deformation. When the auxiliary member 4y / separator 4y2 no longer comes into contact with the drive unit 180h and / or the brake unit 203a, the compression spring 49 releases its elastic force, and the auxiliary member 4y / separator 4y2 extends away from the connecting part 41.

[0238] Preferably, along the rotation axis L21, the driving force receiving member 4 further includes a second step surface 436 that is further away from the connecting portion 41 than the first step surface 435. The base plate 441 is formed as part of the main body portion 4x. Therefore, the base plate 441 can also be regarded as the upper limit plate 437 of the limiting portion 434, and the component forming the second step surface 436 can be regarded as the lower limit plate of the limiting portion 434. The limited portion 4y4 can move between the lower surface 4371 of the upper limit plate 437 and the second step surface 436 of the lower limit plate along the rotation axis L21.

[0239] In some embodiments, the second step surface 436 may also be flush with the first step surface 435, thus simplifying the structure of the driving force receiving member 4, allowing both the compression spring 49 and the limited portion 4y4 to move between the lower surface 4371 of the upper limit plate 437 and the second step surface 436 of the lower limit plate.

[0240] According to the inventive concept of this embodiment, the compression spring 49 can also be replaced by an elastic arm, sponge, rubber, etc., or the function of the above-mentioned retaining member can also be achieved by replacing the compression spring 49 with a tension spring.

[0241] As described above, by configuring the separator 4y2 to be able to move elastically relative to the connecting part 41 / photosensitive drum along the rotation axis L21, it is possible to avoid the separator 4y2 from abutting the driving part 180h and the braking part 203a and being unable to move along the rotation axis M1, thereby improving the flexibility of the connection between the driving force receiving part 4 and the force output part 203 and effectively preventing interference between the driving force receiving part 4 and the force output part 203.

[0242] [Example Thirteen]

[0243] Figure 29 This is an exploded view of the driving force receiving component after it is separated from the driving end cover, according to Embodiment Thirteen of the present invention. Figure 30 This is a cross-sectional view taken along the EE direction of the rotation axis of the driving force receiving device according to Embodiment Thirteen of the present invention.

[0244] like Figure 20 and Figure 21As shown, the charging component 24 is used to charge the surface of the photosensitive drum 21. The charging component 24 rotates by contacting the photosensitive drum 21 and utilizing the friction between the surface of the photosensitive drum 21 and the surface of the charging component 24. To ensure good contact between the photosensitive drum 21 and the charging component 24, the processing box also includes an elastic component 28 for applying a force to the charging component 24, causing the charging component 24 to move closer to the photosensitive drum 21. The elastic component 28 can be a compression spring that applies a pushing force to the charging component 24, or a tension spring that applies a pulling force to the charging component 24. Under the force applied by the elastic component 28, the surface of the charging component 24 maintains good contact with the surface of the photosensitive drum 21. The following description uses a compression spring as an example of the elastic component 28. When the elastic component 28 is a tension spring, the structures involved in this embodiment, as well as embodiments fourteen and fifteen, are also applicable.

[0245] It is understood that the elastic force applied by the elastic member 28 to the charging member 24 will be transmitted to the driving force receiving member 4, which is exposed from the driving end cover 300. Under the action of this elastic force, the friction between the base 43 of the driving force receiving member 4 and the driving end cover 300 will also increase. In particular, in the driving force receiving member 4 provided with the auxiliary member 4y, the auxiliary member 4y is located radially outside the base 43. That is to say, in the driving force receiving member 4 provided with the auxiliary member 4y, the friction between the auxiliary member 4y and the driving end cover 300 and / or the friction between the auxiliary member 4y and the connecting part 44 / main body 4x will increase. The auxiliary member 4y needs to be set to rotate relative to the main body 4x / processing box housing / photosensitive drum 21. The higher the flexibility of the rotation of the auxiliary member 4y, the smoother the connection process between the driving force receiving member 4 and the force output member 203.

[0246] Therefore, based on the above embodiments, one of the objectives of this embodiment is to prevent the resistance from increasing when the auxiliary component 4y rotates, thereby maintaining the rotational flexibility of the auxiliary component 4y.

[0247] The driving force receiver 4 includes a coupled portion 4z and a coupled portion 44, which are joined together, and an auxiliary member 4y rotatable relative to the coupled portion 44. The driving force receiver 4 has a rotation axis L21. In a radial direction perpendicular to the rotation axis L21, the auxiliary member 4y is located between the coupled portion 44 and the coupled portion 4z. Specifically, the coupled portion 4z includes a connecting portion 41, a chassis 42, and a base 43. The base 43 is connected to at least one of the connecting portion 41 and the chassis 42. If the chassis 42 is not provided, the base 43 will be directly connected to the connecting portion 41. As described above, the driving force receiver 4 can also be considered as including a main body portion 4x and a connecting portion 41 and / or a chassis 42 connected to the main body portion 4x. The main body portion 4x includes the base 43 and the coupled portion 44, which are joined together.

[0248] The driving force receiving member 4 includes a connecting part 44 and a base 43 that are connected to each other. The driving force receiving part 46 is disposed in the connecting part 44. The base 43 is cylindrical and includes an outer wall 438 and an inner wall 439 of the base that are arranged radially and form a spacer groove 43c between them. A portion of the auxiliary member 4y is accommodated by the spacer groove 43c. Specifically, the base 43 is cylindrical in shape and includes a radially arranged outer wall 438 and an inner wall 439. The outer wall 438 is further away from the rotation axis L21 than the inner wall 439. Along the radial direction of the driving force receiving member 4, the outer wall 438 and the inner wall 439 are spaced apart to form a gap groove 43c. The inner wall 439 is provided with a protrusion 433 protruding towards the rotation axis L21. The connecting part 44 is provided with a groove that can cooperate with the protrusion 433. Alternatively, the protrusion 433 is provided on the connecting part 44 and the groove is provided on the inner wall 439, as long as the driving force can be transmitted between the connecting part 44 and the connected part 439.

[0249] The auxiliary component 4y in this embodiment can adopt the auxiliary component structure of any of the above embodiments. For example, the auxiliary component 4y includes a carrier 4y1, a separating component 4y2 protruding from the carrier 4y1, an elastic arm 4y3 connected to the carrier 4y1, and a limiting portion 4y4 disposed on the elastic arm 4y3. The carrier 4y1 is annular, forming a receiving cavity 4y6 that can accommodate the connecting portion 44. Preferably, the elastic arm 4y3 is formed by cutting a part of the carrier 4y1, that is, the elastic arm 4y3 can be regarded as part of the carrier 4y1. In this embodiment, at least a portion of the carrier 4y1 is accommodated by the spacer groove 43c. Therefore, along the radial direction of the driving force receiving component 4, the carrier 4y1 is located between the inner wall 439 and the outer wall 438 of the base.

[0250] The connecting part 44 includes a base plate 441, a central column 45 extending from one side of the base plate 441, a driving force receiving part 46, and a driving force transmitting part 442 extending from the other side of the base plate 441. The driving force transmitting part 442 is used to engage with the protrusion 433 to realize the transmission of driving force between the connecting part 44 and the connected part 4z. At least a portion of the base plate 441 can be regarded as the base 461 of the driving force receiving part 46. The driving force receiving part 46 also includes a protrusion 462 that is further away from the rotation axis L21 / central column 45 than the base 461. The protrusion 462 is used to receive driving force.

[0251] Furthermore, the connecting part 44 also includes a flange part 47 for guiding the braking part 203a. Similar to the preferred embodiment eleven, a guide groove 472 is formed between the two flange parts 47, and the surface of the flange part facing the guide groove 472 is formed as a positioning guide surface 471. During the process of the driving force receiving member 4 and the force output member 203 engaging, the inward protrusion 208e in the braking part 203a enters the guide groove 472 and is guided by the positioning guide surface 471, so that the relative position of the main body part 4x of the driving force receiving member 4 and the force output member 203 is determined. Finally, the driving force receiving member 4 and the force output member 203 can be engaged smoothly.

[0252] In some embodiments, the joining portion 44 and the joined portion 4z are formed separately, such as Figure 29 As shown, the connecting part 44 also includes a guide connecting part 443 disposed on the same side as the driving force transmission part 442 and a snap-fit ​​protrusion 444 disposed at the end of the guide connecting part 443. The connecting part 44 and the connected part 4z are connected through the snap-fit ​​protrusion 444. Specifically, the snap-fit ​​protrusion 444 is connected to the connecting part 41 or the chassis 42.

[0253] The drive end cap 300 includes an end cap body 301 and a mounting hole 302 disposed on the end cap body 301. The drive force receiving member 4 is exposed outward through the mounting hole 302, and the mounting hole 302 has an inner surface 3021. Figure 30 As shown, to more clearly illustrate the internal structure of the driving force receiver 4 and the driving end cover 300, the joint 44 is not shown in the figure; when the driving end cover 300 is installed, the base 43 will enter the mounting hole 302, and correspondingly, the outer wall 438 of the base, the inner wall 439 of the base, and the carrier 4y1 located between the outer wall 438 and the inner wall 439 of the base will also enter the mounting hole 302.

[0254] As described above, the carrier 4y1 is located between the outer wall 438 and the inner wall 439 of the base. That is, the outer surface 4y11 of the carrier will not contact the inner surface 3021 of the mounting hole. As long as the gap between the outer wall 438 and the inner wall 439 of the base is greater than the radial dimension of the carrier 4y1, the auxiliary component 4y with the carrier 4y1 can rotate freely. At this time, the outer surface of the outer wall 438 of the base contacts the inner surface 3021 of the mounting hole. Even if the pushing force applied by the elastic member 28 to the charging member 24 is transmitted to the base 43, it will only cause an increase in the friction between the base 43 / outer wall 438 and the inner surface 3021 of the mounting hole, without affecting the auxiliary component 4y. It can be seen that the resistance encountered by the auxiliary component 4y when rotating will not increase, and its rotational flexibility can be maintained.

[0255] In some embodiments, the spacer 43c is arranged along the entire circumference of the driving force receiver 4, so that the rotation trajectory of the auxiliary member 4y will be more stable.

[0256] In other embodiments, the spacer groove 43c is provided with a predetermined arc along the circumferential direction of the driving force receiver 4. Preferably, the direction of the pushing force applied by the elastic member 28 to the charging member 24 passes through the spacer groove 43c. In other words, along the radial direction of the driving force receiver 4, the spacer groove 43c is located in the direction of the pushing force applied by the elastic member 28 to the charging member 24. This also prevents the auxiliary member 4y from contacting the inner wall 3021 of the mounting hole, reduces the resistance encountered by the auxiliary member 4y when rotating, and greatly improves its rotational flexibility. It can be seen that along the radial direction of the driving force receiver 4, at least a portion of the spacer groove 43c / base outer wall 438 is located in the direction of the pushing force applied by the elastic member 28 to the charging member 24, or in other words, at least a portion of the spacer groove 43c / base outer wall 438 is located in the direction of the pushing force of the elastic member 28 to the charging member 24.

[0257] In other embodiments, the spacer groove 4c can also be provided on the auxiliary member 4y. Correspondingly, the mating part 4z is provided with a protrusion for mating with the spacer groove 4c. For example, the outer wall 438 or the inner wall 439 of the base can be regarded as an embodiment of the protrusion. When the inner wall 439 of the base is mated with the spacer groove 4c provided on the auxiliary member 4y, the outer wall 438 of the base can be eliminated. Alternatively, when the outer wall 438 of the base is mated with the spacer groove 4c provided on the auxiliary member 4y, the outer surface of the carrier 4y1 will be directly opposite to the inner wall 3021 of the mounting hole. Even if the auxiliary member 4y is subjected to the pushing force from the elastic member 28, the resistance to the rotation of the auxiliary member 4y will not increase, and its rotational flexibility can be maintained.

[0258] Furthermore, a lubricant can be applied between the outer surface of the carrier 4y1 and the inner wall 3021 of the mounting hole, or the outer surface of the carrier 4y1 and the inner wall 3021 of the mounting hole can be made into smooth surfaces, thereby reducing the resistance experienced by the auxiliary component 4y when rotating.

[0259] [Example Fourteen]

[0260] Figure 31 This is a state diagram of the driving force receiving device after it is separated from the driving end cover according to Embodiment Fourteen of the present invention; Figure 32 This is a cross-sectional view taken along the EE direction of the rotation axis of the driving force receiving device according to Embodiment Fourteen of the present invention.

[0261] In this embodiment, the driving force receiving member 4 does not need to be modified as described in Embodiment Thirteen, and correspondingly, the structure of the driving end cover 300 is changed.

[0262] like Figure 31 and Figure 32 As shown, the driving force receiving member 4 has a rotation axis L21 and includes a connecting part 41, a chassis 42, a base 43, a connecting part 44, and an auxiliary member 4y rotatable relative to the connecting part 44. Along the radial direction perpendicular to the rotation axis L21, the size of the chassis 42 is larger than the size of the connecting part 41 and the base 43. The auxiliary member 4y is located radially outside the connecting part 44, or in other words, the connecting part 44 is located in the receiving cavity 4y6 of the auxiliary member 4y.

[0263] The drive end cap 300 includes an end cap body 301 and a mounting hole 302 provided on the end cap body 301. The drive force receiving member 4 is exposed through the mounting hole 302. Furthermore, the drive end cap 300 also includes a blocking portion 303 extending from the end cap body 301. When the drive end cap 300 is installed, at least a portion of the base 43, at least a portion of the auxiliary member 4y, and the connecting portion 44 ( Figure 32 At least a portion (not shown) enters the mounting hole 302, while the blocking part 303 abuts against the driving force receiving member 4.

[0264] Preferably, the blocking part 303 abuts against the chassis 42, such as Figure 32 As shown, along the radial direction, the blocking part 303 is located outside the mounting hole 302; when the charging member 24 is pressed against the photosensitive drum 21 by the elastic force applied by the elastic member 28, the pressure on the driving force receiving member 4 will be eliminated due to the contact between the blocking part 303 and the chassis 42, and the position of the auxiliary member 4y in the mounting hole 302 will not change. That is to say, the free rotation state of the auxiliary member 4y will not be affected, and correspondingly, the resistance of the auxiliary member 4y when rotating will not increase, and its rotational flexibility can be maintained.

[0265] More preferably, along the pushing direction k of the pushing force applied by the elastic member 28 to the charging member 24, the blocking part 303 abuts against the chassis 42. At this time, the free rotation state of the auxiliary member 4y can be better maintained. It can be seen that along the radial direction of the driving force receiving member 4, at least a part of the blocking part 303 is located on the pushing direction k of the pushing force applied by the elastic member 28 to the charging member 24, or in other words, at least a part of the blocking part 303 is located on the pushing direction k of the elastic member 28 pushing the charging member 24.

[0266] In some embodiments, the blocking part 303 may also be configured to abut against other parts of the driving force receiving member 4. For example, the blocking part 303 abuts against the connecting part 41, which can also prevent the resistance from increasing when the auxiliary member 4y rotates, thereby maintaining the rotational flexibility of the auxiliary member 4y.

[0267] [Example 15]

[0268] Figure 33This is an exploded view of the driving force receiving device according to Embodiment 15 of the present invention; Figure 34 This is a perspective view of the drive end cap according to Embodiment 15 of the present invention; Figure 35 This is a cross-sectional view taken along the EE direction of the rotation axis of the driving force receiving device according to Embodiment 15 of the present invention.

[0269] In this embodiment, the structure of the driving force receiver 4 and the structure of the driving end cover 300 are changed at the same time, but the auxiliary component 4y is not limited and can adopt the structure described in any of the above embodiments. As mentioned above, the driving force receiver 4 can also be regarded as including the coupled part 4z and the coupled part 44 that are coupled together, and the auxiliary component 4y that is rotatable relative to the coupled part 44. The driving force receiver 4 has a rotation axis L21. The coupled part 4z includes a connecting part 41, a chassis 42 and a base 43. The base 43 is connected to at least one of the connecting part 41 and the chassis 42. If the chassis 42 is not provided, the base 43 will be directly connected to the connecting part 41. The auxiliary component 4y is located radially outside the coupled part 44, or in other words, the coupled part 44 is located in the receiving cavity 4y6 of the auxiliary component 4y.

[0270] In this embodiment, the structure of the connecting part 44 is the same as that of the connecting part in embodiment thirteen. The base 43 has a movable cavity 432 and a protrusion 433 located in the movable cavity 432. The connecting part 44 and the base 43 are connected in the same way as in embodiment thirteen, and will not be described again here.

[0271] Furthermore, the driving force receiving member 4 also includes a base 412 disposed in the connecting part 41 and a first stepped surface 435 disposed on the base 412. At least a portion of the base 43 extends from the base 412 along the rotation axis L21. The joined part 4z is also provided with a limiting groove 413. The driving end cover 300 is provided with a limited protrusion 304 that engages with the limiting groove 413. Through the engagement of the limited protrusion 304 with the limiting groove 413, the movement of the photosensitive drum 21 in the radial direction can be restricted.

[0272] The auxiliary component 4y is supported by the first stepped surface 435. Along the radial direction of the driving force receiving component 4, the limiting groove 413 is located on the radial outer side of the auxiliary component 4y. Therefore, the position of the auxiliary component 4y in the mounting hole 302 will not change, the free rotation state of the auxiliary component 4y will not be affected, and correspondingly, the resistance of the auxiliary component 4y when rotating will not increase, and its rotational flexibility can be guaranteed.

[0273] Specifically, the limiting groove 413 can be disposed on either the connecting part 41 or the chassis 42. Along the radial direction, the limiting groove 413 is located radially outside the base 43, or in other words, the limiting groove 413 is further away from the rotation axis L21 than the base 43, and in the radial direction, the limiting groove 413 and the base 43 form the first stepped surface 435. For example... Figure 34 As shown, the drive end cap 300 includes an end cap body 301, a mounting hole 302 disposed on the end cap body 301, and a limiting protrusion 304 extending from the end cap body 301. The limiting protrusion 304 is used to engage with the limiting groove 413. Preferably, the limiting protrusion 304 extends from the radial edge of the mounting hole 302 along the direction of the rotation axis L21. That is, the limiting protrusion 304 surrounds and forms the mounting hole 302.

[0274] In some embodiments, the positions of the limiting groove 413 and the limited protrusion 304 can be interchanged, that is, the limiting groove 413 is provided on the drive end cover 300, and the limited protrusion 304 is provided on the joined portion 4z; similar to the above embodiment, along the radial direction of the driving force receiving member 4, at least a portion of one of the limiting groove 413 and the limited protrusion 304 is located in the direction of the pushing force applied by the elastic member 28 to the charging member 24, or in other words, at least a portion of one of the limiting groove 413 and the limited protrusion 304 is located in the direction in which the elastic member 28 pushes the charging member 24.

[0275] In summary, by setting mutually interlocking limiting members and restricted members along the radial direction of the driving force receiver 4, it is possible to prevent the elastic member 28 from applying a force towards the photosensitive drum 21 to the charging member 24, thereby preventing the driving force receiver 4, which is coaxially arranged with the photosensitive drum 21, from being indirectly forced to push, which would cause the auxiliary member 4y located on the driving force receiver 4 to be squeezed against the inner wall 3021 of the mounting hole on the driving end cover 300, or the auxiliary member 4y to be squeezed against the connecting part 44 / main body part 4x, resulting in increased rotational resistance of the auxiliary member 4y, reduced rotational flexibility of the auxiliary member 4y, and finally, the driving force receiver 4 from being able to smoothly connect with the force output member 203.

[0276] Based on the inventive concept of this invention, along the radial direction of the driving force receiving member 4, the outer surface 4y11 of the supporting member 4y is configured not to contact the inner wall 3021 of the mounting hole, that is, a gap is formed between the outer surface 4y11 and the inner wall 3021 of the mounting hole, or even if the outer surface 4y11 contacts the inner wall of the mounting hole 3021, no compression occurs between the two. In this way, the rotational resistance of the auxiliary member 4y will not increase, and the rotational flexibility of the auxiliary member 4y can be maintained. Therefore, the driving force receiving member 4 and the force output member 203 can be smoothly combined.

[0277] After the limiting member and the limited member are combined, even if the driving force receiving member 4 indirectly receives the force from the elastic member 28, the auxiliary member 4y will not be squeezed against the inner wall 3021 of the mounting hole, or the auxiliary member 4y will not be squeezed against the connecting part 44 / main body 4x. The friction between the auxiliary member 4y and the inner wall 3021 of the mounting hole and / or the friction between the auxiliary member 4y and the connecting part 44 / main body 4x will not increase. Therefore, the resistance when the auxiliary member 4y rotates will not increase, and the rotational flexibility of the auxiliary member 4y can be maintained.

[0278] Preferably, the charging member 24 is forced along the elastic member 28 toward the approach direction k toward the photosensitive drum 21, and at least a portion of the restrained member and one of the restraining members are located in the approach direction k, that is, the restraining member and the restrained member are engaged at least in the approach direction k along the radial direction of the driving force receiving member.

[0279] According to Embodiments Thirteen and Fourteen, the restricted member may be a spacer groove 43c provided in the joined portion 4z, or a chassis 42 / connecting portion 41 provided in the joined portion 4z, or a limiting groove 413 provided in the joined portion 4z. The restricted member may be a part of the auxiliary member 4y itself, or a blocking portion 303 provided on the drive end cover 300, or a limited protrusion 304 provided on the drive end cover 300. In the deformable embodiment, the positions of the restricted member and the restricted member may be interchanged.

[0280] As described above, the charging unit 24 is used to charge the photosensitive drum. Correspondingly, the processing box C is also provided with a charging electrode for receiving power from the imaging device and supplying it to the charging unit 24 (the "charging electrode" and "power receiving unit" mentioned in this specification refer to the same component). The top plate 94 is also provided with a power output component that can make electrical contact with the charging electrode. As the door is closed, the top plate 94 moves downward and abuts against the processing box C, and the power output component makes electrical contact with the charging electrode, thus positioning the processing box C in the imaging device. At the same time, the charging electrode can receive the power output by the power output component. Conversely, when the door is opened, the top plate moves upward away from the processing box C, and the charging electrode loses contact with the power output component.

[0281] Generally, the processing box C also includes a chip that can establish a communication connection with the imaging device. The top plate 94 is equipped with a contact pin that can make electrical contact with the chip. The contact pin is designed to be retractable. As the top plate 94 moves downward, the contact pin abuts against the chip to achieve electrical contact. To simplify the internal circuitry of the imaging device, the chip and the charging electrode are located at the same longitudinal end of the processing box. When the processing box is installed in the predetermined position, the electrical contact portion of the chip for making electrical contact with the contact pin and the charging electrode are both fixed with their faces upward (top plate). In this way, the contact between the contact pin and the electrical contact portion and the contact between the power output component and the charging electrode can be achieved simultaneously.

[0282] However, to achieve a stable electrical connection between the processing unit and the imaging device, namely, stable contact between the stylus and the electrical contact part and stable contact between the power output component and the charging electrode, it is necessary to ensure that the installation position of the charging electrode is accurate. Otherwise, it is difficult to achieve contact between the stylus and the electrical contact part and contact between the power output component and the charging electrode at the same time.

[0283] Therefore, the present invention also provides the following embodiments to improve the stable electrical connection between the processing box and the imaging device; it should be understood that those skilled in the art can also combine at least any of the following embodiments with at least any of the above embodiments according to design requirements. The following description will take the imaging device provided with the drawer-type receiving part and its applicable processing box C as an example.

[0284] Regarding the structure of the processing box C, which is the same as that in the above embodiment, it will not be described again.

[0285] The processing box C also includes a chip C7 for establishing a communication connection with the imaging device. The chip C7 includes a storage section for storing information of the processing box and an electrical contact section C71 electrically connected to the storage section. The electrical contact section C71 and the storage section can be integrated on the same board or set separately. However, the electrical contact section C71 always faces upward and is exposed to the top of the processing box. When the door is closed, the electrical contact section C71 makes electrical contact with the stylus 95.

[0286] Furthermore, the processing box C also includes a charging electrode assembly 8 (such as...) for supplying power to the charging component 24. Figure 36 As shown, the charging electrode assembly 8 is used for electrical contact with the power output component 96. The charging component 24 is rotatably supported by the bracket 26. A spring 28 is disposed between the bracket 26 and the second unit housing 2. The charging component 24 is kept in contact with the photosensitive drum 21 by the pushing force of the spring 28. When the processing cartridge C is working, the metal shaft 241 receives power from the imaging device, causing the charging component 24 to charge the surface of the photosensitive drum 21. When the laser beam carrying imaging information irradiates the surface of the charged photosensitive drum, an electrostatic latent image is formed in the area to be imaged. Subsequently, the developer on the surface of the developing roller 11 develops the electrostatic latent image. In some embodiments, the charging electrode assembly 8 supplies power to the charging component 24 by directly abutting against the metal shaft 241. In other embodiments, the bracket 26 may be made of a conductive material, so that the charging electrode assembly 8 supplies power to the charging component 24 by abutting against the spring 28 or the bracket 26. In the following description of the electrical connection between the charging electrode assembly 8 and the charging component 24, any one of the three abutment methods mentioned above is included.

[0287] Preferably, the electrical contact C71 and the charging electrode assembly 8 are disposed at the non-driving end C2. It is understood that the electrical contact C71 and the power receiving part A81 are disposed at the non-driving end. This prevents vibrations at the driving end from causing instability in the electrical contact between the electrical contact C71 and the stylus 95, and between the charging electrode assembly 8 and the power output component 96. Furthermore, it simplifies the circuitry within the imaging device, allowing components that supply power to the processing box (such as the aforementioned stylus 95 and power output component 96) to be disposed at the non-driving end C2 of the processing box C.

[0288] In some embodiments, the positions of the electrical contact C71 and the charging electrode assembly 8 should not be limited. For example, the electrical contact C71 and the charging electrode assembly 8 may be disposed on any one of the first unit housing 1, the second unit housing 2, and the second end cover 400, respectively or together.

[0289] The electrical contact C71 is located on the second end cover 400. If it is necessary to replace the chip C7 but the chip is difficult to disassemble, the chip C7 and the second end cover 400 can be replaced together. Moreover, since the electrical contact C71 is located on the second end cover 400, the chip C7 and the second end cover 400 can be assembled into a component in advance during the assembly of the processing box.

[0290] The charging electrode assembly 8 is mounted on the second unit housing 2, resulting in a more compact overall layout and easier assembly. Moreover, since the second unit housing 2 is located relative to the second end cover 400, it provides a more stable mounting platform. The charging electrode assembly 8 is less prone to displacement due to external vibrations, further enhancing the stability of the electrical connection.

[0291] Compared to the existing technology that places the power receiving unit A81 on the side of the processing box end cover, this embodiment innovatively integrates the charging electrode assembly 8 onto the second unit housing 2, and fixes it with the power receiving unit A81 facing upwards (top plate). This design eliminates the need for electrode exposure openings on the second end cover 400, thus avoiding structural weaknesses caused by openings. This not only simplifies the design and manufacturing process of the end cover but also significantly enhances the overall strength and impact resistance of the second end cover 400, improving the reliability and service life of the device.

[0292] The following description uses the example of the electrical contact portion C71 and the charging electrode assembly 8 being simultaneously provided on the second end cover 400.

[0293] [Example Sixteen]

[0294] Figure 36 This is a perspective view of the processing box as seen from the non-driving end of the processing box according to Embodiment Sixteen of the present invention; Figure 37This is a side view of the processing box according to Embodiment Sixteen of the present invention when a portion of its components are hidden, viewed from left to right in the left-right direction; Figure 38 This is a perspective view of the top plate in an imaging device to which the processing box of the present invention is applicable; Figure 39A This is a simplified side view of the processing box according to Embodiment Sixteen of the present invention, viewed from left to right in the left-right direction before it comes into contact with the top plate. Figure 39B This is a simplified side view of the processing box according to Embodiment Sixteen of the present invention when viewed from left to right in the left-right direction after it comes into contact with the top plate.

[0295] Before describing the processing box of this embodiment, the power output component 96 will be described first, such as... Figure 38 As shown, with the processing box C installed in the imaging device, the top plate 94 also has the above-mentioned up-down, left-right, and front-back directions. The stylus 95 and the power output component 96 are both exposed downwards. The number of stylus 95 corresponds to the number of electrical contacts C71 of the chip 7. The power output component 96 is a conductor that protrudes downwards from the top plate 94 and has a front conductive surface 962 facing forward, a rear conductive surface 961 facing backward, a left conductive surface 963 facing left, a right conductive surface 965 facing right, and a lower conductive surface 964 facing downward.

[0296] like Figure 37 As shown, the charging electrode assembly A8 includes a power receiving part A81 for receiving power and a power transmitting part A82 for being electrically connected to the charging component 24. The power receiving part A81 and the power transmitting part A82 are electrically connected. Preferably, the power receiving part A81 and the power transmitting part A82 are integrally formed. In this embodiment, the power receiving part A81 and the power transmitting part A82 are integrally formed of conductive material.

[0297] like Figure 36 As shown, the electrical contact C71 and the power receiving part A81 are disposed on the upper part of the non-driving end and exposed upwards towards the housing. Further, the second end cover 400 is also provided with an electrical contact cavity 400a. When the imaging device door is closed, at least the power receiving part A81 is located in the electrical contact cavity 400a. In this embodiment, the power receiving part A81 is fixedly installed in the electrical contact cavity 400a; specifically, the power receiving part A81 is fixed to the front side of the electrical contact cavity 400a. During the downward pressing of the top plate 94, at least a portion of the power output component 96 enters the electrical contact cavity 400a. The electrical contact cavity 400a serves as a positioning guide for the power output component 96 to ensure precise connection between the power output component 96 and the power receiving part A81 and to maintain good electrical contact, thereby maintaining good print quality.

[0298] Before the imaging equipment door is closed, the top plate 94 is in the position as follows: Figure 39AAt the position shown, the top plate 94 is not in contact with the processing box C in the vertical direction, the stylus 95 is separated from the electrical contact C71, and the power output component 96 is also separated from the power receiving component A81. As the imaging device door closes, the top plate 94 gradually moves downward. When the door is fully closed, the top plate 94 comes into contact with the processing box C, the stylus 95 comes into contact with the electrical contact C71 and retracts into the top plate 94, at least a portion of the power output component 96 enters the electrical contact cavity 400a, and the front conductive surface 962 comes into contact with the power receiving component A81. Finally, the electrical contact C71 and the stylus 95 are electrically connected, and the power receiving component A81 and the power output component 96 are also electrically connected. The electrical connection between the processing box and the imaging device will become stable. At the same time, by using the stylus 95 to abut against the electrical contact C71, the processing box C can be stably positioned in the imaging device.

[0299] As a variation of this embodiment, the power receiving unit A81 can also be disposed on the rear side of the electrical contact cavity 400a. When at least a portion of the power output member 96 enters the electrical contact cavity 400a, the rear conductive surface 961 of the power output member 96 contacts the power receiving unit A81. At this time, the force that the power receiving unit A81 may exert on the power output member 96 will be forward. This method can also ensure that the electrical connection between the processing box and the imaging device becomes stable.

[0300] As described above, when the door is closed and the top plate 94 abuts against the processing box C, at least a portion of the power output component 96 enters the electrical contact cavity 400a, and the power receiving part A81 abuts against the side conductive surface (non-bottom conductive surface) of the power output component 96. The force that the power receiving part A81 may exert on the power output component 96 is backward, and the top plate 94 will only be subjected to the upward reaction force exerted by the electrical contact part C71 on the stylus 95. Therefore, the contact between the electrical contact part C71 and the stylus 95 and the contact between the power receiving part A81 and the power output component 96 can be stably achieved, and the electrical connection between the processing box and the imaging device will also become stable.

[0301] [Example 17]

[0302] Figure 40 This is a perspective view of some components in the processing box according to Embodiment Seventeen of the present invention; Figure 41 This is a partial perspective view of the processing box after it comes into contact with the top plate according to Embodiment Seventeen of the present invention.

[0303] Compared to Embodiment Sixteen, the contact position between the charging electrode assembly B8 and the power output component 96 is different in this embodiment, such as... Figure 40 As shown, the power receiving unit B81 is fixedly installed on the right side of the electrical contact cavity 400a, as... Figure 41As shown, when the top plate 94 comes into contact with the processing box C downwards, at least a portion of the power output component 96 enters the electrical contact cavity 400a, the contact pin 95 is electrically connected to the electrical contact part C71, and at the same time the right conductive surface 965 of the power output component 96 contacts the power receiving part B81 to achieve electrical connection.

[0304] Similarly, in this embodiment, the force that the power receiving unit B81 may exert on the power output unit 96 is to the left, and the top plate 94 will only be subjected to the upward reaction force exerted by the electrical contact C71 on the stylus 95. Therefore, the contact between the electrical contact C71 and the stylus 95 and the contact between the power receiving unit B81 and the power output unit 96 can be stably achieved, and the electrical connection between the processing box and the imaging device will also become stable.

[0305] As a variation of this embodiment, the power receiving unit B81 can also be disposed on the left side of the electrical contact cavity 400a. When at least a portion of the power output member 96 enters the electrical contact cavity 400a, the left conductive surface 963 of the power output member 96 makes contact. At this time, the force that the power receiving unit B81 may exert on the power output member 96 will be directed to the right. This method can also ensure that the electrical connection between the processing box and the imaging device becomes stable.

[0306] [Example 18]

[0307] Figure 42 This is a perspective view of some components in the processing box according to Embodiment 18 of the present invention; Figure 43 This is a simplified side view of the processing box according to Embodiment 18 of the present invention when viewed from left to right in the left-right direction before contact with the top plate and after hiding some components; Figure 44 This is a simplified side view of the processing box according to Embodiment 18 of the present invention when viewed from left to right in the left-right direction after it comes into contact with the top plate.

[0308] As shown in the figure, the charging electrode assembly C8 in this embodiment includes a power receiving part C81, a power transmitting part C82, and a toggle member C83. The toggle member C83 is used to toggle the power receiving part C81, so that the power receiving part C81 changes from a first state where it cannot receive power to a second state where it can receive power. Thus, the power from the power output part 96 is transmitted to the charging part 24 in sequence through the toggle member C83, the power receiving part C81, and the power transmitting part C82, or the power is transmitted to the charging part 24 in sequence through the power receiving part C81 and the power transmitting part C82.

[0309] In this embodiment, the toggle member C83 is configured to rotate around a rotation axis. This rotation axis should not be restricted. For example, the rotation axis can be parallel to the left-right direction, parallel to the front-back direction, or parallel to the up-down direction. The power receiving part C81 and the power transmitting part C82 are configured as an integrally formed tension spring. The power receiving part C81 and the power transmitting part C82 are the two ends of the tension spring, respectively. The power receiving part C81 is connected to the toggle member C83, and the power transmitting part C82 is electrically connected to the charging member 24.

[0310] In this embodiment, the rotation axis of the actuating member C83 is parallel to the left-right direction, and the actuating member C83 is made of a non-conductive material. As shown in the figure, the actuating member C83 includes a pressed part C831, a actuating part C832, and a rotating part C833, wherein the pressed part C831 and the actuating part C832 protrude from the rotating part C833. Before the door is closed, or before the top plate 94 abuts against the processing box C, the power receiving part C81 is pulled upward by the tension spring (power receiving part C81), and the pressed part C831 faces downward. Preferably, the pressed part C831 protrudes from the second unit housing 2. When the top plate 94 begins to abut against the processing box C, the pressed part C831 is pressed by the top plate 94 and rotates around the rotation axis. The pressed part C831 moves upward, and at the same time, the actuating part C832 drives the power receiving part C81 to move downward. When the door is fully closed, the pressed part C831 is pressed to the bottom by the top plate 94, and at least a portion of the power output part 96 enters the electrical contact cavity 400. a. The actuating part C832 drives the power receiving part C81 to contact the power output part 96. At the same time, the stylus 95 is electrically connected to the electrical contact part C71. The power receiving part C81 can contact any one of the side conductive surfaces (including conductive surface 962, rear conductive surface 961, left conductive surface 963, and right conductive surface 965) of the power output part 96. At this time, the force that the power receiving part C81 may apply to the power output part 96 is not upward. Therefore, the contact between the electrical contact part C71 and the stylus 95 and the contact between the power receiving part C81 and the power output part 96 can be stably achieved, and the electrical connection between the processing box and the imaging device also becomes stable.

[0311] It should be noted that in this embodiment, the power receiving part C81 can also contact the lower conductive surface 964 of the power output part 96. In this case, although the force applied by the power receiving part C81 to the power output part 96 may be upward, the power receiving part C81 is one end of a tension spring. Therefore, even if the downward pressure applied by the power output part 96 to the power receiving part C81 is large, the power receiving part C81 can offset the large pressure by contracting downward, so that the contact between the power output part 96 and the power receiving part C81 will not weaken the electrical connection between the electrical contact part C71 and the stylus 95. Therefore, in this case, the contact between the electrical contact part C71 and the stylus 95 and the contact between the power receiving part C81 and the power output part 96 can be stably achieved, and the electrical connection between the processing box and the imaging device also becomes stable.

[0312] [Example 19]

[0313] Figure 45 This is a perspective view of some components in the processing box according to Embodiment Nineteen of the present invention; Figure 46 This is a simplified side view of the processing box according to Embodiment 19 of the present invention when viewed from left to right in the left-right direction after it comes into contact with the top plate.

[0314] Compared to Embodiment 18, the actuating element D83 in this embodiment is made of metal. Therefore, in this embodiment, when the top plate 94 abuts against the processing box C, the actuating element D83 does not need to move the power receiving part D81 to contact the power output part 96. Instead, the actuating element D83 itself contacts the power output part 96, and then the actuating element D83 transmits power to the power receiving part D81. Preferably, the actuating part D832 of the actuating element D83 contacts the power output part 96. In this way, the movement path of the power receiving part D81 in the processing box C can be reduced, or even the power receiving part D81 does not need to move, as long as it is ensured that the power receiving part D81 can maintain good electrical contact with the movable actuating element D83.

[0315] Similar to Embodiment 18, when the top plate 94 abuts against the processing box C, at least a portion of the power output component 96 enters the electrical contact cavity 400a, and the actuating component D83 can contact any conductive surface of the power output component 96. Preferably, the actuating part D832 of the actuating component D83 contacts the side conductive surface of the power output component 96.

[0317] Figure 47A and Figure 47BThese are simplified side views of the processing box according to Embodiment 20 of the present invention, viewed from left to right in the left-right direction before and after contact with the top plate.

[0318] In this embodiment, the charging electrode assembly E8 includes a power receiving part E81, a power transmitting part E82, and a toggle member E83. The power transmitting part E82 is electrically connected to the charging part 24, and the toggle member E83 is used to switch the power receiving part E81 from a first state where it cannot receive power to a second state where it can receive power. Unlike embodiments eighteen and nineteen, at least a portion of the toggle member E83 in this embodiment is configured as a rack that can slide in the up and down direction.

[0319] As shown in the figure, the actuating member E83 includes a rack E831, an actuating part E832, and a rotating part E833. The rack E831 extends in the vertical direction, and the actuating part E832 protrudes from the rotating part E833. The rack E831 and the rotating part E833 are provided with teeth that can mesh with each other. At the same time, the power receiving part E81 is connected to the actuating member E83 / actuating part E832, and the power transmitting part E82 is electrically connected to the charging member 24.

[0320] According to Embodiments 18 and 19, the actuating part E832 can be made of either a conductive or non-conductive material. When the top plate 94 is not in contact with the processing box C, preferably, the rack E831 protrudes upwards from the second end cover 400 / second unit housing 2. As the top plate 94 moves downwards towards the processing box C, the upper end of the rack E831 begins to be abutted by the top plate 94, and the rack E831 moves downwards. Subsequently, the rotating part E833 rotates in the direction shown by r5, and the actuating part E832 itself or the actuating part E832 drives the power receiving part E81 to move upwards, as... Figure 47B As shown, when the top plate 94 presses the rack E831 to its lowest position, at least a portion of the power output component 96 enters the electrical contact cavity 400a. The actuating part E832 drives the power receiving part E81 to contact the power output component 96, or the actuating part E832 itself contacts the power output component 96. At the same time, the stylus 95 is electrically connected to the electrical contact part C71. The power receiving part E81 / actuating part E832 can contact any conductive surface of the power output component 96. Therefore, the contact between the electrical contact part C71 and the stylus 95 and the contact between the power receiving part E81 and the power output component 96 can be stably achieved, and the electrical connection between the processing box and the imaging device also becomes stable.

[0321] [Example 21]

[0322] Figure 48A and Figure 48B These are simplified side views of the processing box according to Embodiment 21 of the present invention, viewed from left to right in the left-right direction before and after contact with the top plate.

[0323] Compared with Embodiment 20, in this embodiment, the actuating part F832 of the actuating member F83 is also configured as a rack, the rotating part F833 is located between the rack F831 and the rack F832, the actuating part F832 can be made of either a conductive material or a non-conductive material, the power receiving part F81 is connected to the rack F832, and the rack F832 is used to switch the power receiving part F81 from a first state where it cannot receive power to a second state where it can receive power. As the top plate 94 approaches the processing box C, at least a portion of the power output component 96 gradually enters the electrical contact cavity 400a. The rack F831 gradually moves downward, and through the rotating part F833, the rack F832 gradually moves upward. Finally, the power receiving part E81 contacts the power output component 96, or the rack F832 itself contacts the power output component 96. At the same time, the stylus 95 is electrically connected to the electrical contact part C71. The power receiving part F81 / toggle part F832 can contact any conductive surface of the power output component 96. Therefore, the contact between the electrical contact part C71 and the stylus 95, and the contact between the power receiving part F81 and the power output component 96, can be stably achieved, and the electrical connection between the processing box and the imaging device also becomes stable.

[0324] As a variation of the above embodiment, at least a portion of the separation contact mechanism 5 can also serve as the toggle member. During the movement of the top plate 94 toward the processing box C, the top plate 94 interacts with the separation contact mechanism 5, thereby forcing at least a portion of the separation contact mechanism 5 to move. The at least a portion of the separation contact mechanism 5 causes the power receiving unit to switch from a first state where it cannot receive power to a second state where it can receive power.
