Description

[0001] The present patent application claims priority to the prior application with the name "Box", application number 202221515641.7, filed on June 16, 2022, and the prior application with the name "A container", application number 202221531540.9, filed on June 17, 2022, the entire contents of which are incorporated herein by cross-reference. TECHNICAL FIELD

[0002] The present application relates to the field of electrophotographic imaging, and in particular to a box for an electrophotographic imaging device and a driving force receiving assembly arranged in the box. BACKGROUND

[0003] A common toner cartridge contains toner that can be supplied to an imaging device, and also has a rotating member for stirring or conveying the toner, which is driven to rotate by a driving force from the imaging device when the toner cartridge is in operation in the imaging device. Generally, the toner cartridge includes an integrated structure and a split structure. The integrated structure refers to a toner cartridge that includes both a powder reservoir containing unused toner and a waste powder reservoir containing used toner. The split structure refers to a toner cartridge that includes only the aforementioned powder reservoir.

[0004] To this end, the imaging device will need to be provided with a driving force output member, and the toner cartridge will be provided with a driving force receiving assembly that can be combined with the driving force output member. When the toner cartridge is installed in the imaging device, the driving force receiving assembly is combined with the driving force output member, and when the toner cartridge needs to be removed from the imaging device, the driving force receiving assembly is disengaged from the driving force output member.

[0005] A technology is disclosed in the existing US patent (US20220179355), in which a driving force receiving member and a conversion member are arranged in the driving force receiving assembly. During the process of combining the driving force receiving assembly with the driving force output member, the driving force output member abuts against the conversion member and applies a force to the conversion member, causing the driving force receiving member to deform and thereby complete the combination with the driving force output member. However, this structure requires the conversion member to combine the driving force receiving member and the driving force output member, which is relatively complex. SUMMARY

[0006] The present application provides a driving force receiving assembly and a box, in which the driving force receiving assembly and the driving force output member in the imaging device can smoothly achieve combination and disengagement. On this basis, the structure of the driving force receiving assembly is effectively simplified, and the specific scheme is as follows:

[0011] The driving force receiving assembly further comprises a protruding portion, at least a portion of the protruding portion is radially inside the driving force receiving member, the protruding portion protrudes from the support portion, the limiting slot is recessed radially inward from an outer surface of the protruding portion in a radial direction of the base.

[0012] When the driving force receiving assembly gradually approaches the driving force output member, the driving force receiving member directly contacts the driving force output member and deforms in a direction away from the axis of rotation until the driving force receiving portion enters the combining port, the driving force receiving portion extends / protrudes towards the axis of rotation in a radial direction of the base.

[0013] The protruding portion is movable relative to the support portion along the axis of rotation.

[0014] When the driving force receiving assembly gradually approaches the driving force output member, the driving force receiving member directly contacts the driving force output member and deforms in a direction close to the axis of rotation until the driving force receiving portion enters the combining port, the driving force receiving portion extends / protrudes away from the axis of rotation in a radial direction of the base.

[0045] Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0046] Figure 1 is a perspective view of the cartridge according to the present application; Figure 2 is a perspective view of the driving force output member in the image forming apparatus according to the present application.

[0047] The cartridge 100 includes a housing 1 in which toner is contained, and a rotating member 2 rotatably installed in the housing 1, which can be selected according to the structural characteristics of the cartridge 100. For example, when the cartridge 100 is provided with a developing assembly including a developing member and / or a toner feeding member, the rotating member 2 can be any one of the developing member, the toner feeding member, and a stirring member (not shown) for stirring the toner, which is used to supply the toner outward. Further, when the cartridge 100 is provided with the developing assembly and an image forming assembly including a photosensitive member, the rotating member 2 can be any one of the developing member, the toner feeding member, the stirring member, and the photosensitive member. When the cartridge 100 is not provided with the developing assembly, the rotating member 2 is generally the stirring member. In this case, the cartridge 100 can be a toner cartridge or a toner bag, etc. The stirring member prevents the toner from being agglomerated and also supplies the toner outward during the operation / image forming process of the cartridge 100.

[0048] As shown in Figure 1 , the cartridge 100 has a length direction which is a longitudinal direction, one longitudinal end of which is provided with a driving force receiving assembly 3, which can be referred to as a driving end F, and the other end opposite to the driving end F is a non-driving end E. The driving force receiving assembly 3 is used to be combined with a driving force output member 200 provided in an image forming apparatus, and to receive the driving force outputted by the driving force output member 200 to drive the rotating member 2 to rotate.

[0049] As shown in Figure 2 , the driving force output member 200 includes a driven portion 201 for receiving the driving force provided by a driving force source, a barrel 202 extending from the driven portion 201, and a combination port 205 provided on the circumferential wall of the barrel 202. A part of the driven portion 201 becomes a bottom wall 206 of the barrel 202. An accommodation space 203 is formed inside the barrel 202. An opening 207 is formed on the side opposite to the bottom wall 206. An end face 204 is formed on the side where the opening 207 is located. When the cartridge 100 is installed, a part of the driving force receiving assembly 3 enters the combination port 205. With the rotation of the driving force output member 200 around a rotation axis L1, one of the faces 205a / 205b of the combination port 205 serves as a driving face to be combined with the driving force receiving assembly 3, thereby driving the driving force receiving assembly 3 to rotate.

[0050] Embodiment One

[0051] Figure 3 is a perspective view of the driving force receiving assembly involved in the first embodiment of the present application; Figure 4 is an exploded view of the driving force receiving assembly involved in the first embodiment of the present application; Figure 5 is a view of the combined state of the driving force receiving assembly and the driving force output member involved in the first embodiment of the present application.

[0052] As shown in Figure 3 , the driving force receiving assembly 3 has an axis of rotation L2, and comprises a base 31, a support portion 32 extending from the base 31, and a driving force receiving member 34 supported by the support portion 32, the driving force receiving member 34 is arranged to be movable in the radial direction of the base 31 or the radial direction of the circular track formed around the axis of rotation L2, so as to realize the combination and disengagement of the driving force receiving assembly 3 and the driving force output member 200.

[0053] As shown in Figure 4 , along the axis of rotation L2, two support portions 32 spaced apart from each other extend from the base 31, respectively, and a space 33 is formed between them, and the space 33 is provided with an opening in a direction perpendicular to the axis of rotation L2, further, at least a part of the driving force receiving member 34 is located radially outside the space 33; the driving force receiving member 34 is rotatably supported by the support portion 32, the driving force receiving member 34 comprises a rotating portion 341, a pressing portion 342 and a driving force receiving portion 343 connected to the rotating portion 341, respectively, the driving force receiving portion 343 has a force receiving portion 343a for combination with the driving force output member 200, optionally, the force receiving portion 343a can be a face, also can be a point, also can be a line, that is, the force receiving portion 343a and the driving force output member 200 can form at least any one of face combination, point combination and line combination.

[0054] The driving force receiving member 34 and the support portion 32 are axially matched, generally, either an axle can be arranged on the rotating portion 341 and a hole can be arranged on the support portion 32, or vice versa, a hole can be arranged on the rotating portion 341 and an axle can be arranged on the support portion 32. As shown in Figure 4As shown, the driving force receiving assembly 3 further comprises a shaft 38 combined with the rotating part 341, which can increase the convenience of combining the driving force receiving part 34 with the supporting part 32, i.e. the driving force receiving part 34 is first inserted into the space 33, and then the shaft 38 is sequentially inserted through the hole pre-set on the supporting part 32 and the rotating part 341; the shaft 38 can also be integrally formed with the rotating part 341, at this time, the length of the shaft 38 will be slightly greater than the distance between the two supporting parts 32, and the rotating part 341 provided with the shaft 38 is directly installed to the supporting part 32. When the driving force receiving assembly 3 is assembled, along the rotation axis L2, at least a part of the pressed part 342 is closer to the base 31 than the driving force receiving part 343, and at least a part of the pressed part 342 is located outside the space 33, in the radial direction of the base 31, the size of the supporting part 32 is smaller than the inner diameter of the cylinder 202, and the minimum distance from the pressed part 342 to the rotation axis L2 is greater than half of the inner diameter of the cylinder 202, so that the pressed part 342 can abut against the cylinder 202, so that the driving force receiving part 343 is away from the rotation axis L2, in the direction perpendicular to the rotation axis L2, the driving force receiving part 343 is entirely located in the space 33, which is to prevent the driving force receiving part 343 protruding from the space 33 from interfering with the driving force output part 200, when the size of the supporting part 32 in the direction perpendicular to the rotation axis L2 is set to be much smaller than the inner diameter of the cylinder 202, the driving force receiving part 343 will be allowed to be located outside the space 33, but the maximum size of the combination of the supporting part 32 and the driving force receiving part 343 in the direction perpendicular to the rotation axis L2 is still smaller than the inner diameter of the cylinder 202, further, the space 33 can be referred to as a limiting groove, at least a part of the limiting groove is closer to the rotation axis L2 than the driving force receiving part 34 in the radial direction of the base 31 / driving force receiving assembly 3, the limiting groove can accommodate at least a part of the driving force receiving part 34, so that the driving force receiving part 34 will not be broken under external force.

[0055] As Figure 5As shown, when the driving force receiving assembly 3 gradually approaches the driving force output member 200, for example, the driving force receiving assembly 3 gradually approaches the driving force output member 200 along with the installation of the cartridge 100, a part of the combination formed by the support portion 32 and the driving force receiving portion 343 enters the receiving space 203 of the barrel 202, the end face 204 of the driving force output member 200 is in contact with the pressed portion 342, as the driving force receiving assembly 3 continuously moves towards the driving force output member 200, the end face 204 extrudes the pressed face 342, further causing the driving force receiving member 34 to rotate around the rotating portion 341, the driving force receiving portion 343 enters the combination port 205, along the circumferential direction of the driving force receiving assembly 3, the stress portion 343a is opposite to the driving face 205a / 205b, the rotation axis L1 and the rotation axis L2 are substantially collinear, at the same time, along the rotation axis L1 / L2, the driving force receiving portion 343 is also combined with the limiting face 2051 of the combination port 205, to prevent the driving force receiving assembly 3 and the driving force output member 200 from being separated from each other, the limiting face 2051 can be the same face as the driving face 205a / 205b, or can be a different face, for example, the limiting face 2051 can also be Figure 2 of the other two faces in the combination port 205 that is close to the end face 204 in the axial direction, in this way, the driving force receiving assembly 3 completes the combination with the driving force output member 200.

[0056] When the driving force output member 200 rotates around the rotation axis L1, the driving face 205a / 205b transmits the driving force to the stress portion 343a, finally, the driving force receiving assembly 3 is driven, at the same time, the driving force receiving assembly 3 can also transmit the driving force outwards through the driving force transmission member arranged on the base 31, the driving force transmission member can be a gear (illustrated as a gear), can also be an irregular polygon, etc. When the driving force receiving assembly 3 needs to be separated from the combination with the driving force output member 200, only needs to apply a force to the driving force receiving assembly 3 in the direction opposite to the combination direction, for example, the driving force receiving assembly 3 gradually moves away from the driving force output member 200 along with the removal of the cartridge 100, so that the driving force receiving portion 343 is separated from the limiting face.

[0057] Further, the driving force receiving assembly 3 can further be provided with a reset member combined with the driving force receiving member 34, the reset member being used to force the driving force receiving member 34 to a position not interfering with the barrel 202, in particular, the reset member is used to force the driving force receiving part 343 to move in a direction away from the position where the driving force receiving part 343 is combined with the driving force output member 200. When the pressed part 342 is pressed by the end face 204, the reset member accumulates a reset force, when the end face 204 is no longer pressed by the pressed part 342, the reset force of the reset member forces the driving force receiving member 34 to rotate again (in a direction making the driving force receiving part 343 away from the combined port 205), and the driving force receiving part 343 returns to the position not interfering with the inner wall of the barrel 202 again.

[0058] Embodiment Two

[0059] Figure 6 is a perspective view of the driving force receiving assembly involved in Embodiment Two of the present application; Figure 7 is an exploded view of the driving force receiving assembly involved in Embodiment Two of the present application; Figure 8 is a view of the combined state of the driving force receiving assembly and the driving force output member involved in Embodiment Two of the present application.

[0060] The same components in this embodiment as those in the above embodiments will be given the same reference numerals. As shown in Figure 6 and Figure 7 The driving force receiving assembly 3 comprises a base 31, a support part 32 combined with the base 31, a driving force receiving member 34 supported by the support part 32, and a reset member 35 combined with the driving force receiving member 34. In this embodiment, the driving force receiving member 34 is arranged to be movable along the rotation axis L2, the base 31 is provided with a limiting part 311 forming a limiting cavity 312, the reset member 35 is an elastic member limited by the limiting part 311, the reset member 35 is accommodated into the limiting cavity 312 and is limited by the limiting part 311 to prevent deviation, preferably, the reset member 35 is a compression spring, the support part 32 is a solid body extending from the base 31, comprising a base part 321 and a combined part 322 connected with the base part 321, the driving force receiving member 34 is arranged to be movably combined with the combined part 322, one end of the reset member 35 enters the limiting cavity 312 and abuts against the base 31, and the other end abuts against the driving force receiving member 34.

[0061] The driving force receiving member 34 comprises a main body 344, a pressed part 342 connected with the main body 344, and a driving force receiving part 343 combined with the pressed part 342. The main body 344 has a bottom wall 348 and a side wall extending from the bottom wall 348 along the rotation axis L2. An opening 346 is formed on the side wall, and a cavity 347 is formed between the opposite side walls. An abutting part 345 extends from the side wall towards the cavity 347. The pressed part 342 extends towards the cavity 347. Preferably, at least two pressed parts 342 are provided, and the at least two pressed parts 342 gradually approach each other along the extension direction of the pressed part 342. Correspondingly, the combined part 322 is provided with a pushing surface 323 gradually approaching the rotation axis L2. Further, the opening 346 can be referred to as a limiting slot, which can accommodate at least a part of the driving force receiving member 34, for example, a part or the whole of the driving force receiving part 343.

[0062] As shown in Figure 8 When the driving force receiving assembly 3 gradually approaches the driving force output member 200, for example, the driving force receiving assembly 3 gradually approaches the driving force output member 200 along with the installation of the cartridge 100, the driving force receiving member 34 enters the receiving space 203 of the barrel 202, and the reset member 35 is compressed and gradually deformed to accumulate the reset force. At the same time, the inclined pushing surface 323 gradually pushes the pressed part 342, so that the pressed part 342 drives the driving force receiving part 343 to deform away from the rotation axis L2, until the driving force receiving part 343 enters the combined port 205. At this time, the rotation axis L1 and the rotation axis L2 are substantially collinear. Along the circumferential direction of the driving force receiving assembly 3, the stressed part 343a is opposite to the driving surface 205a / 205b, and the driving force receiving part 343 is also limited by the limiting surface 2051 in the combined port 205. Therefore, the driving force receiving assembly 3 will not be separated from the driving force output member 200.

[0063] When the driving force output member 200 starts to rotate around the rotation axis L1, the driving surface 205a / 205b applies a driving force to the stressed part 343a, and the driving force receiving assembly 3 can be driven to rotate around the rotation axis L2.

[0064] When an acting force is applied in a direction opposite to the direction in which the driving force receiving assembly 3 is combined with the driving force output member 200, for example, the driving force receiving assembly 3 gradually moves away from the driving force output member 200 along with the removal of the cartridge 100, the driving force receiving part 343 is no longer limited by the limiting surface, the reset member 35 releases the reset force, and the driving force receiving part 343 gradually moves towards the rotation axis L2 to be separated from the combined port 205. In this way, the driving force receiving assembly 3 is separated from the driving force output member 200.

[0065]

Embodiment Three

[0066] Figure 9 is a perspective view of the driving force receiving assembly involved in the third embodiment of the present application; Figure 10 is a side view of the driving force receiving assembly involved in the third embodiment of the present application, viewed along the rotation axis thereof; Figure 11 is a schematic view of the driving force receiving assembly involved in the third embodiment of the present application, combined with the driving force output member.

[0067] The same components as those in the above embodiments will be designated by the same reference numerals. As shown in Figure 9 the driving force receiving assembly 3 comprises a base 31, a support portion 32 connected with the base 31, and driving force receiving members 34 supported by the support portion 32, the support portion 32 being a pedestal extending from the base 31, the two driving force receiving members 34 being oppositely arranged along the radial direction of the base 31, specifically, the driving force receiving member 34 being a cantilever extending from the support portion 32, comprising a connecting arm 349 connected with the support portion 32, and a driving force receiving portion 343 combined with the connecting arm 349, the two driving force receiving portions 343 being oppositely arranged along the direction perpendicular to the rotation axis L2, both of the two driving force receiving portions 343 extending / protruding toward the rotation axis L2 in the radial direction of the base 31, and the minimum distance between the two driving force receiving portions 343 being less than the diameter of the opening 207; further, the driving force receiving member 34 further comprises a pressed portion 342 arranged adjacent to the driving force receiving portion 343, at least a part of the pressed portion 342 being farther away from the base 31 than the driving force receiving portion 343 along the rotation axis L2.

[0068] As shown in Figure 11 when the driving force receiving assembly 3 gradually approaches the driving force output member 200, for example, when the driving force receiving assembly 3 gradually approaches the driving force output member 200 along with the installation of the cartridge 100, the end face 204 presses the pressed portion 342, and the driving force receiving member 34 reaches the outside of the barrel 202, so that the two driving force receiving members 34 are deformed in the direction away from the rotation axis L2 until the distance between the two driving force receiving portions 343 exceeds the diameter of the opening 207, and then, as the driving force receiving assembly 3 continues to approach the driving force output member 200, the driving force receiving portion 343 enters the combined opening 205 and moves in the direction approaching the rotation axis L2, the stress receiving portion 343a is opposite to the driving face 205a / 205b, and the rotation axis L1 and the rotation axis L2 are substantially collinear, when the driving force output member 200 starts to rotate around the rotation axis L2, the driving face 205a / 205b transmits driving force to the stress receiving portion 343a, and thus, the driving force receiving assembly 3 is driven. During the combination of the driving force receiving assembly 3 and the driving force output member 200, the driving force receiving member 34 directly abuts / contact with the driving force output member 200, without the need of deforming the driving force receiving member 34 through another component, and thus, the structure of the driving force receiving assembly 3 can be simplified.

[0069] When an external force is applied in a direction opposite to the direction in which the driving force receiving assembly 3 approaches the driving force output member 200, for example, the driving force receiving assembly 3 gradually moves away from the driving force output member 200 as the cartridge 100 is taken out, the driving force receiving portion 343 moves again in a direction away from the rotation axis L2 until the driving force receiving portion 343 is disengaged from the engaging opening 205, and finally, the driving force receiving assembly 3 is completely disengaged from the driving force output member 200.

[0070] Further, as shown in Figure 9 and Figure 10 , the driving force receiving assembly 3 in the embodiment further comprises a protruding portion 313 arranged between the driving force receiving members 34, that is, at least a part of the protruding portion 313 is located radially inward of the driving force receiving members 34, or at least a part of the driving force receiving members 34 is located radially outward of the protruding portion 313, the protruding portion 313 protrudes from the support portion 32, and the protruding direction of the protruding portion 313 is the same as the protruding direction of the driving force receiving members 34 along the rotation axis L2, a limiting groove 314 radially opposite to the driving force receiving members 34 is formed on the protruding portion 313, the limiting groove 314 is recessed radially inward from the outer surface of the protruding portion 313 along the radial direction of the base 31, further, at least a part of the limiting groove 314 is closer to the rotation axis L2 than the driving force receiving members 34 along the radial direction of the base 31 / driving force receiving assembly 3, the limiting groove 314 can accommodate at least a part of the driving force receiving members 34, when the driving force receiving assembly 3 is not engaged with the driving force output member 200, a part of the driving force receiving portion 343 enters the limiting groove 314, which can avoid the external force acting on the driving force receiving members 34 to cause them to break.

[0071] Further, as shown in Figure 10 , along the rotation axis L2, it can be observed that the pressing portion 342 and the driving force receiving portion 343 are not blocked, so that the structure of the driving force receiving assembly 3 can be further simplified.

[0073] Figure 12A is a perspective view of the driving force receiving assembly involved in Embodiment Four of the application; Figure 12B is an exploded view of the driving force receiving assembly involved in Embodiment Four of the application; Figure 13 is a schematic view of the state of the driving force receiving assembly and the driving force output member involved in Embodiment Four of the application after being engaged; Figure 14 is a schematic view of a variant of Embodiment Four of the application.

[0074] Unlike Embodiment Three, the driving force receiving assembly 3 in the embodiment reaches the engaging opening 205 from the inside of the barrel 202, as shown in Figure 12A and Figure 12BAs shown, the driving force receiving assembly 3 includes a base 31, a support portion 32 connected to the base 31, and driving force receiving members 34 supported by the support portion 32. The support portion 32 is a limiting portion 311 extending from the base 31. Two driving force receiving members 34 extend from the support portion 32 in a direction away from the base 31. In the radial direction of the base 31, both driving force receiving portions 343 extend / protrude in a direction away from the rotation axis L2.

[0075] The driving force receiving member 34 includes a connecting arm 349 connected to the support portion 32, a driving force receiving portion 343 disposed on the connecting arm 349, and a pressed portion 342 disposed adjacent to the driving force receiving portion 343. Along the rotation axis L2, at least a portion of the pressed portion 342 is further away from the base 31 than the driving force receiving portion 343. Thus, when the driving force receiving assembly 3 is combined with the driving force output member 200, the pressed portion 342 is first pressed by the driving force output member 200, causing the driving force receiving member 34 to deform. Furthermore, along the rotation axis L2, it can be observed that the pressed portion 342 and the driving force receiving portion 343 are not obstructed, which simplifies the structure of the driving force receiving assembly 3.

[0076] like Figure 13 As shown, when the driving force receiving component 3 gradually approaches the driving force output component 200, for example, as the driving force receiving component 3 gradually approaches the driving force output component 200 with the installation of the box 100, the end face 204 presses the pressed part 342, and the driving force receiving component 34 reaches the interior of the cylinder 202, causing the two driving force receiving components 34 to deform in the direction closer to the rotation axis L2 until the distance between the two driving force receiving parts 343 is less than the diameter of the opening 207. As the driving force receiving component 3 continues to approach the driving force output component 200, the driving force receiving part 343 enters the joint 205 and moves in the direction away from the rotation axis L2. The force receiving part 343a is opposite to the driving surface 205a / 205b, and the rotation axis L1 and the rotation axis L2 are basically collinear. When the driving force output component 200 begins to rotate around the rotation axis L1, the driving surface 205a / 205b transmits driving force to the force receiving part 343a, and thus, the driving force receiving component 3 is driven. During the process of combining the driving force receiving component 3 with the driving force output component 200, the driving force receiving component 34 directly abuts / contacts with the driving force output component 200 without the need for deformation of the driving force receiving component 34 through additional components. This simplifies the structure of the driving force receiving component 3.

[0077] When the force is applied in the direction opposite to the direction in which the driving force receiving assembly 3 approaches the driving force output member 200, for example, the driving force receiving assembly 3 gradually moves away from the driving force output member 200 as the cartridge 100 is taken out, the driving force receiving part 343 moves again in the direction approaching the rotation axis L2 until the driving force receiving part 343 is disengaged from the engaging opening 205, and finally, the driving force receiving assembly 3 is completely disengaged from the driving force output member 200.

[0078] Further, as shown in Figure 12B the driving force receiving assembly 3 in the embodiment further comprises a protruding part 313 arranged between the driving force receiving members 34, that is, at least a part of the protruding part 313 is located radially inside the driving force receiving members 34, or at least a part of the driving force receiving members 34 is located radially outside the protruding part 313, the protruding part 313 protrudes from the support part 32 but is not connected to the support part 32, that is, the protruding part 313 is movable relative to the support part 32, and the restoring member 35 is arranged between the protruding part 313 and the support part 32 for urging the protruding part 313 in the direction away from the base 31; at the same time, the support part 32 is further provided with a guide protrusion 315 so that the protruding part 313 moves along a predetermined track.

[0079] The protruding direction of the protruding part 313 is the same as the protruding direction of the driving force receiving member 34 along the rotation axis L2, and a limiting groove 314 radially opposite to the driving force receiving member 34 is formed on the protruding part 313, the limiting groove 314 is recessed radially inward from the outer surface of the protruding part 313 along the radial direction of the base 31, further, at least a part of the limiting groove 314 is closer to the rotation axis L2 than the driving force receiving member 34 along the radial direction of the driving force receiving assembly 3, the limiting groove 314 can accommodate at least a part of the driving force receiving member 34, and when the driving force receiving member 34 moves in the direction approaching the rotation axis L2, the limiting groove 314 can limit the movement distance of the driving force receiving member 34 to prevent the driving force receiving member 34 from being broken; in addition, when the driving force output member 200 applies driving force to the driving force receiving assembly 3, the side of the driving force receiving member 34 not subjected to force is in contact with the limiting groove 314 to prevent the driving force receiving member 34 from being broken due to excessive driving force, and at the same time, the connecting arm 349 can also be protected by the limiting groove 314. It can be understood that the limiting groove 314 in Embodiment Three also has the same effect.

[0080] Based on the inventive idea of the embodiment, the driving force receiving assembly 3 can also have a structure as shown in Figure 14In the shown deformation design, the driving force receiving member 34 is still provided with the connecting arm 349 connected with the support part 32 and the driving force receiving part 343 combined with the connecting arm 349, the pressed part 342 is arranged adjacent to the driving force receiving part 343 along the rotation axis L2, and at least a part of the pressed part 342 is farther away from the base 31 than the driving force receiving part 343. Further, along the rotation axis L2, it can be observed that the pressed part 342 and the driving force receiving part 343 are not blocked, so that the structure of the driving force receiving assembly 3 can be simplified.

[0081] In the process of combining the driving force receiving assembly 3 with the driving force output member 200, the end face 204 abuts against the pressed part 342, so that the driving force receiving member 34 is deformed towards the direction close to the rotation axis L2 until the driving force receiving part 343 enters the combined port 205, at which time the driving force receiving part 343 is deformed towards the direction away from the rotation axis L2.

[0082] Further, the support part 32 is also provided with the accommodating groove 37, when the driving force receiving member 34 is deformed towards the direction close to the rotation axis L2, the pressed parts 342 close to each other can be accommodated by the accommodating groove 37, so that the interference between the driving force receiving member 34 and the driving force output member 200 can be avoided. In the embodiment, the accommodating groove 37 has the same function as the limiting groove 314 described above, and the accommodating groove 37 can also be called a limiting groove. Similarly, in the process of combining the driving force receiving assembly 3 with the driving force output member 200, the driving force receiving member 34 directly abuts against / contacts the driving force output member 200, without the need for deforming the driving force receiving member 34 through another component, so that the structure of the driving force receiving assembly 3 can be simplified.

[0083]

Embodiment Five

[0084] Figure 15 is a perspective view of the driving force receiving assembly involved in Embodiment Five of the application; Figure 16 is an exploded view of the driving force receiving assembly involved in Embodiment Five of the application; Figure 17 is a schematic view of the combined state of the driving force receiving assembly and the driving force output member involved in Embodiment Five of the application.

[0085] In the above embodiments, the pressed part 342 and the driving force receiving part 343 in the driving force receiving member 34 are combined in a mutual contact manner, in the embodiment, the pressed part 342 and the driving force receiving part 343 no longer contact each other, and the two interact with each other through magnetic force.

[0086] As Figures 15-17As shown, the driving force receiving assembly 3 in the embodiment includes a base 31, a support portion 32 connected with the base 31, a driving force receiving member 34 supported by the support portion 32, and a reset member 35 between the base 31 and the driving force receiving member 34. In addition to the driving force receiving portion 343 and the pressed portion 342, the driving force receiving member 34 further includes a magnetic action assembly 36 between the pressed portion 342 and the driving force receiving portion 343. The pressed portion 342 forces the driving force receiving portion 343 to move between a first position where the driving force can be received and a second position where the driving force cannot be received, by the attraction force or repulsion force of the magnetic action assembly 36.

[0087] The magnetic action assembly 36 includes a first magnetic member 361 mounted on the pressed portion 342 and a second magnetic member 362 mounted on the driving force receiving portion 343. The driving force receiving portion 343 is arranged to be rotatable about an axis, and the pressed portion 342 is arranged to be movable relative to the base 31 along the rotation axis L2. Before the driving force receiving assembly 3 is combined with the driving force output member 200, the first magnetic member 361 and the second magnetic member 362 do not interact under the action of the reset member 35. At this time, the pressed portion 342 is in an extended position, or in other words, along the rotation axis L2, the pressed portion 342 is in a position away from the base 31, and the driving force receiving portion 343 is in the second position close to the rotation axis L2 and cannot receive the driving force. When the driving force receiving assembly 3 starts to be combined with the driving force output member 200, the driving force receiving portion 343 does not interfere with the cylinder body 202. When the pressed portion 342 starts to contact the bottom wall 206 of the cylinder body 202, the reset member 35 is elastically deformed to accumulate a reset force, the pressed portion 342 gradually approaches the base 31, the first magnetic member 361 and the second magnetic member 362 gradually approach each other and gradually start to interact, and under the action of the attraction force or repulsion force between the first magnetic member 361 and the second magnetic member 362, the driving force receiving portion 343 rotates about the axis in a direction away from the rotation axis L2 to reach the first position where the driving force can be received. Further, the groove where the driving force receiving portion 343 is located can be referred to as a limiting groove. At least a portion of the limiting groove is closer to the rotation axis L2 than the driving force receiving member 34 in the radial direction of the base 31 / driving force receiving assembly 3, and the limiting groove can accommodate at least a portion of the driving force receiving member 34. In some embodiments, the driving force receiving portion 343 can be omitted, and the second magnetic member 362 can be regarded as a driving force receiving portion, so that the structure of the driving force receiving assembly 3 can be simplified.

[0088] When the driving force receiving assembly 3 receives a force in the opposite direction of the direction in which the driving force receiving assembly 3 and the driving force output 200 are combined, for example, the driving force receiving assembly 3 gradually moves away from the driving force output 200 as the cartridge 100 is removed, the reset member 35 releases the reset force, and the pressed part 342 gradually moves away from the base 31, the first magnetic member 361 and the second magnetic member 362 gradually move away from each other and gradually stop interacting with each other, and the driving force receiving part 343 gradually moves from the first position in which driving force can be received to the second position in which driving force cannot be received.

[0089] It can be implemented that the reset member 35 is cancelled, and during the process in which the driving force receiving assembly 3 and the driving force output 200 are combined, the magnetic force of the magnetic action assembly 36 is also used to force the pressed part 342 to gradually move away from the base 31, so that the driving force receiving part 343 gradually moves from the first position in which driving force can be received to the second position in which driving force cannot be received.

Embodiment Six

[0091] Figure 18 is a perspective view of the driving force receiving assembly involved in Embodiment Six of the application; Figure 19 is an exploded view of the driving force receiving assembly involved in Embodiment Six of the application.

[0092] Unlike Embodiment Five, this embodiment also uses the magnetic action assembly 36 to realize the mutual combination and disengagement of the driving force receiving assembly 3 and the driving force output 200, and the difference is that the driving force receiving part 343 moves in a translational manner between the first position and the second position.

[0093] As shown in Figure 18 and Figure 19 , the protruding part 313 protrudes from the support part 32, the limiting groove 314 is arranged on the protruding part 313, and the second magnetic member 362 is movably mounted on the limiting groove 314; further, the second magnetic member 362 and the driving force receiving part 343 can also be integrally formed, which can further simplify the structure of the driving force receiving assembly 3, and at the same time, the driving force receiving part 343 and the pressed part 342 can not have to be in contact by using the action of the magnetic action assembly 36, which not only can reduce the friction between them, but also can simplify the structure of the driving force receiving assembly 3.

Embodiment Seven

[0095] Figure 20 is a schematic view of the state of the driving force receiving assembly involved in Embodiment Seven of the application before being combined with the driving force output; Figure 21 is a schematic view of the state of the driving force receiving assembly involved in Embodiment Seven of the application after being combined with the driving force output; Figure 22This is a comparison diagram of the state changes of the driving force receiving component before and after it is combined with the driving force output component according to Embodiment 7 of the present invention.

[0096] This embodiment is a variation of embodiment four, such as... Figure 20 As shown, the driving force receiving member 34 in this embodiment includes a first part 34a and a second part 34b that are connected to each other. When the driving force receiving member 34 is pressed by the driving force output member 200, the first part 34a and the second part 34b can move relative to the base 31 at the same time. Preferably, the first part 34a and the second part 34b have the same structure and are mirror images of each other relative to the rotation axis L2.

[0097] Taking Part 1, 34a as an example, such as Figure 20 As shown, the first part 34a includes a connecting arm 349 connected to the support part 32 and an adapter arm 340 connected to the connecting arm 349. The part between the connecting arm 349 and the adapter arm 340 is the driving force receiving part 343. A pressed part 342 is formed on the side of the adapter arm 340 away from the connecting arm 349. The pressed part of the first part 34a and the pressed part of the second part 34b are combined to form the pressed part 342 of the driving force receiving member 34.

[0098] The connecting arm 349 and the adapter arm 340 are both inclined relative to the rotation axis L2 and intersect. The intersection of the two can be regarded as the driving force receiving part 343, such as... Figure 22 As shown, before the driving force receiving component 3 and the driving force output component 200 are combined, there is a first distance between the two driving force receiving parts 343 in the direction perpendicular to the rotation axis L2. This first distance is less than the inner diameter of the cylinder 202. At this time, the driving force receiving component 3 can be successfully combined with the driving force output component 200. A part of the support part 32 and the driving force receiving component 34 can be successfully entered into the receiving space 203. When the bottom wall 206 of the cylinder 202 contacts the pressed part 342, the driving force receiving component 34 begins to deform towards the base 31. At this time, the distance between the two driving force receiving parts 343 gradually increases to a second distance greater than the inner diameter of the cylinder 202 and enters the joint 205. The pressed part 342 will be pressed by the bottom wall 206 of the cylinder 202 so that the driving force receiving part 343 and the driving surface 205a / 205b remain opposite. Therefore, the driving force receiving component 3 can receive the driving force output by the driving force output component 200.

[0099] When the bottom wall 206 of the cylinder 202 no longer presses the pressed part 342, the driving force receiving member 34 can be reset by its own elastic force or a reset member between the driving force receiving member 34 and the support part 32 / base 31, the distance between the two driving force receiving parts 343 returns from the second distance to the first distance, and the driving force receiving assembly 3 can be smoothly disengaged from the driving force output member 200. Similarly, the driving force receiving member 34 in the embodiment can still be provided with the accommodating groove 37 accommodating the pressed part 342.

[0100] The above embodiments introduce the combination and disengagement of the driving force receiving assembly 3 and the driving force output member 200 based on one inventive concept, and the following introduces how the driving force receiving assembly 3 moves towards the driving force output member 200 and away from the driving force output member 200 based on another inventive concept.

[0101]

Embodiment Eight

[0102] Figure 23 is a perspective view of the driving force receiving assembly involved in the eighth embodiment of the application; Figure 24A and Figure 24B is a comparison diagram of the state of the driving force receiving assembly involved in the eighth embodiment of the application before and after being combined with the driving force output member.

[0103] The driving force receiving assembly 3 includes a driving force receiving member A31, a trigger member A32, and a magnetic assembly A33, the trigger member A32 is used to receive a trigger signal to trigger the magnetic assembly A33, the magnetic assembly A33 applies a force to the driving force receiving member A31, so that the driving force receiving member A31 is combined with or disengaged from the driving force output member 200.

[0104] In the embodiment, after the trigger member A32 sends a trigger signal, the magnetic assembly A33 forces the driving force receiving member A31 to move by magnetic force. The trigger member A32 is provided as a rotating lever that can rotate around a rotation axis, including a receiving end A321 for receiving a trigger signal, a trigger end A322 for triggering the magnetic assembly A33, and a rotating part A323, the magnetic assembly A33 includes a driving member A332 and a driven member A331 arranged oppositely, wherein the trigger end A322 is combined with the driving member A332, and the driven member A331 is combined with the driving force receiving member A31, in the embodiment, at least one of the driving member A332 and the driven member A331 is a magnet, and when one of them is a magnet, the other can also be a magnetizable metal.

[0105] The trigger signal received by the trigger end A321 can be the operation of closing the door cover of the imaging device, when the door cover touches the trigger end A321, the trigger A32 starts to move, the trigger signal can also be generated by the interaction between the cartridge 100 and the imaging device during the process of installing the cartridge 100 to the imaging device, for example, when the cartridge 100 contacts a certain position of the guide part of the imaging device, the force of the guide part on the cartridge 100, or the force generated during the gradual opening of the protective component installed on the cartridge 100 during the installation process of the cartridge 100.

[0106] The active element A332 and the trigger end A322 are combined in a shaft hole matching mode, as shown in the figure, the trigger end A322 is provided as a long hole, the connecting shaft is connected with the trigger end A322 and enters the long hole A322, further, the connecting shaft is integrated with the active element A322 or is formed separately; further, the driving force receiving assembly 3 further comprises a guide groove A34, the active element A332 is movably arranged in the guide groove A34.

[0107] As shown in Figure 24A and Figure 24B , before receiving the trigger signal, the active element A332 and the driven element A331 are in a state of moving away from each other, the driving force receiving element A31 is not combined with the driving force output element 200, when the trigger end A321 receives the trigger signal, the trigger A32 rotates around the rotating part A323, at the same time, the trigger end A322 drives the active element A332 to move along the direction d to approach the driven element A331, through the repulsive force between the active element A332 and the driven element A331, the driving force receiving element A31 combined with the driven element A331 is forced to move in the direction of approaching the driving force output element 200, until Figure 24B , the driving force receiving element A31 is combined with the driving force output element 200.

[0108] Further, the driving force receiving assembly 3 further comprises a reset element 35 combined with the driving force receiving element A31 or the driven element A331, when the driving force receiving element A31 is combined with the driving force output element 200, the reset element 35 is deformed to accumulate reset force, when the active element A332 gradually moves away from the driven element A331, the reset element 35 releases the reset force to make the driving force receiving element A31 and the driving force output element 200 disengage. Preferably, the reset element 35 is a tension spring, one end of which is connected with the driving force receiving element A31, and the other end is connected with the shell 1.

[0109]

Example Nine

[0110] Figure 25 is the perspective view of the driving force receiving assembly before it is combined with the driving force output element involved in the ninth embodiment of the present application.

[0111] In this embodiment, the driving member A332 and the driven member A331 are still provided as magnets, and the driving member A332 is arranged to be rotatable about the rotation axis L, and through the rotation of the driving member A332, the magnetic force between the driving member A332 and the driven member A331 is changed from attraction to repulsion, or from repulsion to attraction.

[0112] The same components as in Embodiment Eight will be given the same reference numerals. As shown in Figure 25 the driving force receiving assembly 3 comprises a driving force receiving member A31, a triggering member A32, a magnetic assembly A33 and a transmission member A36, the triggering member A32 is arranged in the form of a gear and a rack to trigger the magnetic assembly A33 after receiving a triggering signal, specifically, the triggering member A32 is arranged as a rack, the transmission member A36 is arranged as a gear meshing with the rack, and any one end of the rack A32 can be considered as a receiving end A321, and the teeth arranged on the rack A32 for meshing with the gear A36 are triggering ends A322; the magnetic assembly A33 comprises a driving member A332 combined with the gear A36 and a driven member A331 combined with the driving force receiving member A31, and the driving member A332 and the driven member A331 can interact with each other through magnetic force, thereby achieving the purpose of controlling the combination and disengagement of the driving force receiving member A31 and the driving force output member 200.

[0113] When the driving force receiving member A31 is in a state of disengagement from the driving force output member 200, the driving member A332 and the driven member A331 can either be attracted to each other by attraction, or the position of the driving member A332 can be controlled so that the driving member A332 and the driven member A331 do not attract or repel each other. When the receiving end A321 receives a triggering signal, the driving gear A36 rotates, and the driving member A332 rotates with the rotation of the gear A36, and the triggering time / strength of the triggering signal can be set to make the angle through which the rack A32 drives the gear A36 satisfy the repulsion between the driving member A332 and the driven member A331, and the driving force receiving member A31 will gradually approach the driving force output member 200 along the direction d to complete the combination.

[0114] When the driving force receiving member A31 needs to disengage from the driving force output member 200, the triggering member A32 is triggered again, the gear A36 continues to rotate in the original direction or in the opposite direction, and the driving member A332 and the driven member A331 will generate an attractive force, thereby forcing the driving force receiving member A31 to move in the direction opposite to the direction d to disengage from the driving force output member 200.

[0115] In this embodiment, the driving member A332 is arranged to rotate to switch the magnetic force between the driving member A332 and the driven member A331 between attraction and repulsion, thereby achieving the purpose of controlling the driving force receiving member A31 to move along the direction d to combine with the driving force output member 200 and move along the direction opposite to the direction d to disengage from the driving force output member 200. The reset member 35 in Embodiment Eight can be omitted, so that the overall structure of the driving force receiving assembly 3 can be simplified. From the aspect of the working stability of the driving force receiving assembly 3, the reset member 35 can also be arranged in the driving force receiving assembly 3 to ensure that the disengagement process of the driving force receiving member A31 from the driving force output member 200 is faster.

[0116] As a variation of this embodiment, the mechanism for rotating the driving member A332 can be a connecting rod mechanism, a cam swing lever mechanism, a belt transmission mechanism, etc. in addition to the rack and pinion engagement mechanism described above, which can rotate the driving member A332 by at least 180°.

[0117] As another variation of this embodiment, the positions of the rack A32 and the pinion A36 can also be interchanged, i.e., the pinion A36 as a trigger and the rack A32 as a transmission. In this variation, the movement of the driving member A332 will be the same as in Embodiment One, which will not be described here.

[0118]

Embodiment Ten

[0119] Figure 26 is a perspective view of the driving force receiving assembly according to Embodiment Ten before being combined with the driving force output member.

[0120] The driving force receiving assembly 3 in this embodiment still includes the driving force receiving member A31, the trigger A32, and the magnetic assembly A33. The trigger A32 is an electrical signal control unit, and the magnetic assembly A33 includes the driving member A332 connected to the electrical signal control unit A32 and the driven member A331 combined with the driving force receiving member A31. Specifically, the driving member A332 is an electromagnet, and when the electrical signal control unit A32 receives a trigger signal, the coil of the electromagnet A332 is energized to generate a magnetic force between the electromagnet A332 and the driven member A331.

[0121] It can be understood that when the coil of electromagnet A332 receives a current in one direction, the electromagnet A332 and the driven piece A331 will generate one of the attractive force or repulsive force, and when the coil of electromagnet A332 receives a current in another direction, the electromagnet A332 and the driven piece A331 will generate the other of the attractive force or repulsive force, so that the magnetic force generated between the electromagnet A332 and the driven piece A331 can be determined according to the needs of the driving force receiving piece A31, specifically, when the driving force receiving piece A31 needs to be combined with the driving force output piece 200, the electromagnet A332 and the driven piece A331 will generate a repulsive force, thereby making the driving force receiving piece A31 gradually approach the driving force output piece 200 along the direction d, and when the driving force receiving piece A31 needs to be separated from the driving force output piece 200, the electromagnet A332 and the driven piece A331 will generate an attractive force, thereby making the driving force receiving piece A31 gradually move away from the driving force output piece 200 along the direction opposite to the direction d. Figure 26 Figure 26

[0122] Therefore, the magnetic force generated inside the magnetic assembly A33 in the embodiment can be converted between the attractive force and the repulsive force according to the movement needs of the driving force receiving piece A31, compared with the ninth embodiment, the driving piece A332 in the embodiment is replaced by an electromagnet, and the volume of the driving force receiving assembly 3 can be reduced; further, the driving force receiving assembly 3 in the embodiment can also continue to be provided with a reset piece 35, to ensure that the separation process of the driving force receiving piece A31 and the driving force output piece 200 is faster.

[0123] Embodiments eight to ten describe that the driving force receiving piece A31 is combined with and separated from the driving force output piece 200 by the control of the trigger piece A32 on the driving piece A332, it can be realized that the driving piece A332 and the driven piece A331 can also be interchanged in position, or in other words, the driving force receiving piece A31 is combined with and separated from the driving force output piece 200 by the control of the trigger piece A32 on the driven piece A331; compared with the existing mechanical structure for realizing the extension and contraction control of the driving force receiving piece A31, the above-mentioned scheme realizes the extension and contraction control of the driving force receiving piece A31 by using magnetic field force, so that the overall structure of the driving force receiving assembly 3 can be effectively simplified, and the wear inside the driving force receiving assembly 3 is smaller.

[0124] In summary, the driving force receiving assembly 3 structure involved in the application is simplified, and the driving force receiving piece 34 is also not easy to be broken, at the same time, the driving force receiving assembly 3 can also smoothly realize the combination and separation with the driving force output piece 200.​​
