Description

[0001] This application claims the priority of a prior Chinese application with an application date of July 28, 2023, an application number of 202322024324.6, and an invention title of "Drive Force Receiving Component and Cartridge", and all the contents of the prior application are cross-referenced in this application. Technical Field

[0002] The present utility model relates to the field of electrophotographic imaging, and particularly to a cartridge detachably installed in an electrophotographic imaging device and a drive force receiving component located in the cartridge. Background Art

[0003] A cartridge is a container detachably installed in an electrophotographic imaging device (hereinafter referred to as "imaging device"), which contains toner required for the operation of the imaging device. When the imaging device performs imaging, the cartridge receives a driving force from the imaging device to drive a rotatable member rotatably provided therein, and through this rotatable member, the toner is agitated or conveyed outward.

[0004] U.S. Patent No. US11693333B2 discloses a toner cartridge provided with a baffle and a drive force receiving member. The baffle is used not only to close the powder outlet of the cartridge but also to receive a driving force from the imaging device to drive a rotatable member provided in the cartridge to rotate. As the drive force receiving member gradually engages with the drive force output member in the imaging device, the baffle abuts against a predetermined position in the imaging device and gradually no longer closes the powder outlet.

[0005] However, in actual use, this structure has the following defects:

[0006] 1. The process of engaging the drive force receiving member with the drive force output member and the process of the baffle moving from the closed position closing the powder outlet to the open position opening the powder outlet occur simultaneously, which places high requirements on the dimensional accuracy and installation position of the baffle, such that the baffle can only abut against a predetermined position in the imaging device. Otherwise, it may occur that the drive force receiving member and the drive force output member have been engaged, but the baffle has not yet moved from the closed position to the open position.

[0007] 2. During the process of the baffle moving towards the open position, the baffle also exerts a force on the drive force receiving member, thereby forcing the drive force receiving member to be able to engage with the drive force output member. This requires the initial position of the baffle to be accurately determined. Otherwise, it may occur that the baffle and the drive force receiving member interfere with each other, resulting in both being unable to move.

[0008] 3. When the engagement process between the drive force receiving member and the drive force output member gets stuck, even if the baffle has reached the open position, the rotatable member cannot receive the driving force, and the toner contained in the cartridge will not be able to reach the powder outlet smoothly.

[0009] 4. The structure of the driving force receiving member is relatively complex, which is not conducive to the assembly of the driving force receiving member. Summary of the Utility Model

[0010] The present utility model provides a driving force receiving assembly and a cartridge adopting the following technical solutions to solve at least one of the above technical problems. The specific solutions are as follows:

[0011] A driving force receiving assembly is used to be combined with a driving force output member provided in an imaging device to receive a driving force. The driving force output member includes a device-side driving main body and a driving force output surface provided on the device-side driving main body. The device-side driving main body is divided into a device-side first driving main body and a device-side second driving main body which are radially oppositely arranged through a strip-shaped groove provided therein.

The strip-shaped groove extends in the front-rear direction to the rear end of the device side driving member. The driving force output surface is located on the device side first driving body and the device side second driving body.

[0021] In some embodiments, the driving force receiving assembly further includes a second reset member for forcing the connecting member to move forward. One end of the second reset member is connected to the connecting member, and the other end is connected to the cartridge side driving body.

[0055] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0056] [Imaging device and cartridge]

[0057] Figure 1 It is a perspective view of the cartridge involved in the present utility model and the imaging device to which it is applicable being separated from each other.

[0058] The cartridge C can be detachably installed on the imaging device P. The cartridge C can be either a toner cartridge that only contains toner, or a developing cartridge that contains toner and a developing component, or a processing cartridge that contains toner, a developing component, and an imaging component. The developing component includes a developing roller for carrying toner on its surface, and the imaging component includes a photosensitive drum for forming an electrostatic latent image on its surface. A rotatable member is provided in each of the toner cartridge, the developing cartridge, and the processing cartridge. The rotatable member can be used for stirring toner, conveying toner outwards, or forming an electrostatic latent image on its surface, etc., and the rotatable member always receives driving force from the imaging device P.

[0059] The imaging device P includes a main component 101, a cover door 102, a cartridge installation cavity 103, and a driving force output member 4. The cover door 102 is rotatably connected to the main component 101. The cartridge installation cavity 3 is open towards the side of the main component 101. When the cover door 102 rotates from the cartridge detachable position to the cartridge positioning position along the Figure 1 direction shown by r1 in the figure, the cartridge installation cavity 103 is closed, and the cartridge C is positioned in the main component 101. On the contrary, when the cover door 102 is alongFigure 1 When rotating from the cartridge positioning position to the cartridge detachable position in the opposite direction of the direction shown by r1, the cartridge installation cavity 103 is opened, and the cartridge C can be installed or detached.

[0060] Both the cartridge installation cavity 103 and the driving force output member 4 are provided in the main assembly 101. Specifically, the driving force output member 4 is provided in the cartridge installation cavity 103.

[0061] The cartridge C includes a cartridge body 1, a driving force receiving assembly 2, and a shutter assembly 3. Both the driving force receiving assembly 2 and the shutter assembly 3 are provided in the cartridge C in a manner movable relative to the cartridge body 1. Among them, the driving force receiving assembly 2 is used to engage with the driving force output member 4 to receive the driving force, and the shutter assembly 3 is used to move between a closed position where the powder outlet 1d1 of the cartridge C can be closed (as Figure 3 shown) and an open position where the powder outlet 1d1 is opened. When the shutter assembly 3 is in the closed position, the powder outlet 1d1 is closed, and the toner accommodated in the cartridge body 1 cannot flow out. When the shutter assembly 3 is in the open position, the powder outlet 1d1 is opened, and the toner accommodated in the cartridge body 1 can flow out.

[0062] The driving force receiving assembly 2 shown can be switched between a driving state and a stationary state. When the driving force receiving assembly 2 is driven by the driving force output member 4, the driving force receiving assembly 2 switches from the stationary state to the driving state. When the driving force output member 4 no longer outputs the driving force to the driving force receiving assembly 2, the driving force receiving assembly 2 switches from the driving state to the stationary state.

[0063] It should be understood that there is no association between the driving state of the driving force receiving assembly 2 and the open position of the shutter assembly 3, nor between the stationary state of the driving force receiving assembly 2 and the closed position of the shutter assembly 3. When the driving force receiving assembly 2 is driven, the shutter assembly 3 can either have already reached the open position or start moving from the closed position towards the open position. The force used to force the shutter assembly 3 to move from the closed position towards the open position can come either from the mutual abutment between the shutter assembly 3 and the main assembly 101, or from the driving force output member 4, or from the driving force receiving assembly 2. In the latter two cases, when the driving force receiving assembly 2 is driven, the driving force output member 4 directly outputs a force to the shutter assembly 3, or the driving force receiving assembly 2 can output a force to the shutter assembly 3.

[0064] The following takes the example of the shutter assembly 3 moving from the closed position to the open position by mutually abutting against the main assembly 101 for illustration.

[0065] As Figure 1As shown, at least a part of the driving force receiving component 2 protrudes from the cartridge body 1. The installation direction of the cartridge C is defined as the front, the disassembly direction of the cartridge C is defined as the rear, the front and the rear are opposite to each other, the direction intersecting the front-rear direction is the left-right direction, the left and the right are opposite to each other, and the direction intersecting both the front-rear direction and the left-right direction is the up-down direction, the up and the down are opposite to each other; preferably, the front-rear direction, the left-right direction, and the up-down direction are perpendicular to each other. Along the left-right direction, the driving force receiving component 2 is arranged closer to the right, and along the up-down direction, the driving force receiving component 2 is arranged closer to the bottom; the cartridge installation cavity 103 opens backward.

[0066] The cartridge body 1 may include only a single component or may include a plurality of components combined with each other, such as Figure 1 As shown, the cartridge body 1 includes a first body 1a, a second body 1b, and a third body 1c arranged in sequence from front to back in the front-rear direction, and the driving force receiving component 2 protrudes from the first body 1a.

[0067] [Embodiment 1]

[0068] Figure 2 is a perspective view of the cartridge having the driving force receiving component according to Embodiment 1 of the present invention; Figure 3 and Figure 4 is an exploded view of the driving force receiving component according to Embodiment 1 of the present invention separated from the housing of the cartridge; Figure 5 is a perspective view of the driving force receiving component according to Embodiment 1 of the present invention after being combined with the driving force output member.

[0069] (Driving force output member)

[0070] First, the structure of the driving force output member 4 will be introduced below.

[0071] The driving force output member 4 has a rotation axis L4 extending in the front-rear direction, such as Figure 2 As shown, the driving force output member 4 includes a device-side driving member 41 and a device-side driving gear 42 connected to each other. Among them, the device-side driving gear 42 is used to receive driving force from a driving source provided in the imaging device to drive the device-side driving member 41 to rotate. The device-side driving member 41 includes a device-side driving main body 411 and a driving force output surface 413 provided on the device-side driving main body 411. Overall, the device-side driving member 41 is formed as a cylinder, in which a coupling cavity 414 is formed. Along the circumferential direction, the device-side driving main body 411 is separated by a strip-shaped groove 412 provided therein into a device-side first driving main body 411a and a device-side second driving main body 411b arranged radially opposite to each other. The strip-shaped groove 412 extends in the front-rear direction to the rear end of the device-side driving member 41. The strip-shaped groove 412 and the coupling cavity 414 open backward and communicate with the outside in the radial direction of the device-side driving member 41 through the strip-shaped groove 412.

[0072] The front end of the coupling cavity 414 forms an abutting end face 415, and the rear end of the device-side main body 411 forms an end portion 416. Since the coupling cavity 414 also opens backward, the end portion 416 can also be regarded as formed at the rear end of the coupling cavity 414. The surfaces of the device-side first driving main body 411a facing the strip-shaped groove 412 and the device-side second driving main body 411b facing the strip-shaped groove 412 respectively form a first driving force output surface 413a and a second driving force output surface 413b. Along the rotation direction r4 of the driving force output member 4, the first driving force output surface 413a and the second driving force output surface 413b are oppositely arranged, and both the first driving force output surface 413a and the second driving force output surface 413b can output driving force to the driving force receiving assembly 2.

[0073] (Shield assembly)

[0074] Continue as Figure 2 shown, the cartridge C further includes a powder outlet portion 1d connected to the cartridge main body 1 / second main body 1b. At least a part of a rotating member (not shown) is rotatably provided in the powder outlet portion 1d. The driving force receiving assembly 2 is directly or indirectly connected to the rotating member to drive the rotating member to rotate. The rotating member can be, for example, a stirring member for stirring toner, or a member for transmitting driving force to other components in the cartridge C, etc. The powder outlet portion 1d is provided with a powder outlet 1d1 that opens downward (as Figure 3 shown), and a part of the shield assembly 3 moves between the open position and the closed position by moving in a direction intersecting the up-down direction.

[0075] The shield assembly 3 includes a shielding member 31, an abutting member 32, a guiding member 33, and a first restoring member 34. The shielding member 31 is used to shield the powder outlet 1d1 or communicate with the powder outlet 1d1. The abutting member 32 is used to abut against the main assembly 101 to drive the shielding member 31 to move, so that the shielding member 31 moves from the closed position towards the open position. The guiding member 33 is used to guide the shielding member 31 so that the shielding member 31 moves along a predetermined path. The first restoring member 34 is used to provide a restoring force for the shielding member 31 so that the shielding member 31 moves from the open position towards the closed position. The first restoring member 34 can be set as a compression spring, rubber, sponge, tension spring, etc. Preferably, the shielding member 31 and the abutting member 32 are integrally formed, which is not only beneficial to simplifying the structure of the shield assembly 3, but also can improve the transmission efficiency of the pushing force that forces the shielding member 31 to move from the closed position towards the open position. At least one of the shielding member 31 and the abutting member 32 is also integrally formed with the guiding member 33 to more precisely control the movement trajectory of the shielding member 31.

[0076] In some embodiments, the abutting member 32 is further provided with an abutting portion 321 for abutting against the abutted member 104 in the imaging device. Preferably, the abutting portion 321 is a groove provided on the abutting member 32.

[0077] The shielding member 31 is provided with a communication port 311. When the communication port 311 is offset from the powder outlet 1d1, the powder outlet 1d1 is closed and the shielding member 31 is in the closed position. When the communication port 311 is opposite to the powder outlet 1d1, the powder outlet 1d1 is opened and the shielding member 31 is in the open position. Therefore, when the abutting member 32 abuts against the abutted member 104, the shielding member 31 can reach the open position from the closed position either by moving backward or by moving forward.

[0078] (Driving force receiving assembly)

[0079] The driving force receiving assembly 2 includes a driving force receiving member 21 and a driving force transmitting member 22 which are connected to each other. The driving force receiving member 21 is used to combine with the driving force output member 4 to receive the driving force, and the driving force transmitting member 22 is used to transmit the driving force. For example, the driving force transmitting member 22 directly or indirectly drives the rotating member to rotate, or the driving force transmitting member 22 directly or indirectly forces the shielding member 31 to move from the closed position to the open position.

[0080] The driving force receiving member 21 includes a cartridge-side driving main body 211, a connecting member 213 and an acting member 214. The cartridge-side driving main body 211 is provided in a cylindrical shape and forms an activity cavity 212 inside. The connecting member 213 is connected to both the cartridge-side driving main body 211 and the acting member 214 at the same time. When the driving force receiving member 21 combines with the driving force output member 4, the acting member 214 is used to enter the strip-shaped groove 412. As the driving force output member 4 rotates around the rotation axis L4 in the direction shown by r4, the acting member 214 abuts against the driving force output surface 413 to receive the driving force. Subsequently, the driving force is transmitted to the cartridge-side driving main body 211 through the connecting member 213. In this embodiment, the acting member 214 is arranged to be movable between a close position close to the rotation axis L2 and a far position away from the rotation axis L2. When the acting member 214 is in the far position, as the driving force output member 4 rotates, the driving force is transmitted from the driving force output member 4 to the driving force receiving member 21. When the acting member 214 is in the close position, the driving force cannot be transmitted from the driving force output member 4 to the driving force receiving member 21.

[0081] Preferably, the two connecting members 213 are arranged opposite to each other in the radial direction of the driving force receiving member 21. Correspondingly, the two acting members 214 are also arranged opposite to each other in the radial direction of the driving force receiving member 21.

[0082] In some embodiments, even if only one connecting member 213 and one acting member 214 are provided, they can still receive the driving force from the driving force output member 4.

[0083] In this embodiment, the cassette-side driving main body 211 has a rotation axis L2 extending in the front-rear direction. The connecting member 213 is a cantilever formed on the cassette-side driving main body 211. Along the front-rear direction (the extending direction of the rotation axis L2), one end of the connecting member 213 is connected to the cassette-side driving main body 211, and the acting member 214 is connected to the other end of the connecting member 213. Along the rotation direction r2, there is an interval between the connecting member 213 and the cassette-side driving main body 211. In this way, when an external force acts on the acting member 214, the connecting member 213 can swing around one end of the connecting member. Therefore, the connecting member 213 can be regarded as a part of the cassette-side driving main body 211, or rather, the connecting member 213 is formed by cutting the cassette-side driving main body 211. Similar to the device-side driving main body 411, along the rotation direction r2, the cassette-side driving main body 211 is also separated by the connecting member 213 into a first cassette-side driving main body 211a and a second cassette-side driving main body 211b that are radially opposed. The connecting member 213 is located between the first cassette-side driving main body 211a and the second cassette-side driving main body 211b, and there are intervals between the connecting member 213 and the first cassette-side driving main body 211a and between the connecting member 213 and the second cassette-side driving main body 211b. This can not only enable the connecting member 213 to swing effectively but also prevent the connecting member 213 from breaking due to excessive driving force.

[0084] The acting member 214 is a protrusion protruding from the connecting member 213. Before an external force acts on the acting member 214, at least a part of the acting member 214 protrudes from the circumferential surface of the cassette-side driving main body 211. The acting member 214 has a squeezing force receiving surface 215, a driving force receiving surface 216, and a guiding surface 217. Among them, the squeezing force receiving surface 215 is used to receive the squeezing force applied substantially in the up-down direction, thereby forcing the acting member 214 to drive the connecting member 213 to swing around one end of the connecting member. Along the rotation direction r2 / r4, the driving force receiving surface 216 is used to face the driving force output surface 413 to receive the driving force. During the combination of the driving force receiving member 2 and the driving force output member 4, the guiding surface 217 is used to abut against the driving force output member 4 / device-side driving main body 411 to reduce the combination resistance between the driving force receiving member 2 and the driving force output member 4.

[0085] (Combination of the driving force receiving member and the driving force output member)

[0086] When the cartridge C is pushed forward in the cartridge mounting cavity 103, the rotation axes L2 and L4 are substantially coaxial. Along the radial direction of the cartridge-side drive body 211, at least a part of the actuator 214 protrudes from the cartridge-side drive body 211. Along the rotation axis L2, when the actuator 214 is aligned with the strip groove 412, the actuator 214 directly enters the strip groove 412. At this time, along the rotation direction r2 / r4, the driving force receiving surface 216 is directly opposite to the driving force output surface 413, and the cartridge-side drive body 211 enters the engagement cavity 414. As the driving force output member 4 rotates, the driving force is transmitted to the driving force receiving member 21.

[0087] In another case, along the rotation axis L2, when the actuator portion 214 is not aligned with the strip groove 412, the actuator 214 cannot directly enter the strip groove 412. At this time, the guide surface 217 abuts against the rear end (end portion 416) of the device-side drive body 411. Therefore, the actuator 214 will move into the movable cavity 212, or rather, the actuator 214 moves in the direction close to the rotation axis L2. The connecting member 213 also moves relative to the cartridge-side drive body 211, so that the cartridge-side drive body 211 can smoothly enter the engagement cavity 414. At the same time, the device-side drive body 411 presses the extrusion force receiving surface 215, and the actuator 214 moves in the direction close to the rotation axis L2 until it no longer protrudes from the cartridge-side drive body 211. The circumferential outer surface of the cartridge-side drive body 211 contacts the circumferential inner surface of the device-side drive body 411. In this way, the driving force receiving assembly 2 can receive the driving force more stably.

[0088] In some embodiments, when the cartridge-side drive body 211 enters the device-side drive body 411, the circumferential outer surface of the cartridge-side drive body 211 and the circumferential inner surface of the device-side drive body 411 may not contact. At this time, the actuator 214 may still be in a position protruding from the cartridge-side drive body 211, but compared with before the cartridge-side drive body 211 enters the device-side drive body 411, the actuator 214 will be closer to the rotation axis L2.

[0089] As the driving force output member 4 rotates 0°-180° around the rotation direction r4, the actuator 214 enters the strip groove 412, the extrusion force receiving surface 215 is no longer squeezed by the device-side drive body 411, and the driving force receiving surface 216 is opposite to the driving force output surface 413. Finally, the driving force is transmitted from the driving force output member 4 to the driving force receiving member 21.

[0090] In this embodiment, during the combination of the driving force receiving assembly 2 and the driving force output member 4, the shielding plate assembly 3 makes the shielding member 31 move from the closed position to the open position by abutting against the abutted member 104. Compared with the prior art, the structure of this embodiment has the following beneficial effects:

[0091] 1. The movement of the driving force receiving component 2 and the movement of the shutter component 3 are independent of each other, and their movements do not interfere with each other. In this way, the dimensional accuracy requirements and the installation position accuracy requirements of the shutter component 3 can be reduced, and the shutter component 3 / abutment 32 can be selected to abut against more positions in the imaging device, as long as the shielding member 31 can reach the open position from the closed position. The design freedoms of both the driving force receiving component 2 and the shutter component 3 are improved.

[0092] 2. The movement of the driving force receiving component 2 can also be associated with the movement of the shutter component 3, but the shutter component 3 is arranged to move in response to the movement of the driving force receiving component 2, that is, after the driving force receiving component 2 starts to move, the shutter component 3 starts to move. For example, the shielding member 31 is driven by the driving force receiving component 2 to reach the open position from the closed position. This method can ensure that the opening of the powder outlet 1d1 does not occur earlier than the driving force receiving component 2 receives the driving force, and can ensure the smooth output of toner.

[0093] [Embodiment 2]

[0094] Figure 6A is a perspective view of the driving force receiving component related to Embodiment 2 of the present utility model; Figure 6B is a cross-sectional view of the driving force receiving component related to Embodiment 2 of the present utility model after being cut by a plane passing through its rotation axis; Figure 7A is a perspective view of the driving force receiving component related to Embodiment 2 of the present utility model after being combined with the driving force output member; Figure 7B is a cross-sectional view of the driving force receiving component related to Embodiment 2 of the present utility model after being combined with the driving force output member and cut by a plane passing through the rotation axis of the driving force receiving component.

[0095] Different from Embodiment 1, the driving force receiving component 2 in this embodiment further includes a pressing member 24 and a second reset member 23 movably disposed in the movable cavity 212. The pressing member 24 is arranged to move in the front-back direction along the rotation axis L2, and is used to press the acting member 214 away from the position. The second reset member 23 is used to push the pressing member 24 forward away from the driving force transmission member 22.

[0096] In the first embodiment, before the driving force receiving component 2 is combined with the driving force output member 4, along the radial direction of the driving force receiving member 21, the connecting member 213 does not extend beyond the circumferential surface of the box-side driving main body 211. Preferably, the radial outer surface of the connecting member 213 and the circumferential surface of the box-side driving member 211 are on the same circumferential surface; in this embodiment, before the driving force receiving component 2 is combined with the driving force output member 4, along the radial direction of the driving force receiving member 21, the connecting member 213 also does not extend beyond the circumferential surface of the box-side driving main body 211, but the radial outer surface of the connecting member 213 is closer to the rotation axis L2 than the circumferential surface of the box-side driving member 211. This setting can reduce the size of the driving force receiving member 21 in the radial direction.

[0097] The pressing member 24 includes a guiding portion 241 and a pressing portion 242. The guiding portion 241 extends in the front-rear direction and is used to guide the movement of the pressing member 24. The pressing portion 242 is used to press the acting portion 214 in a direction away from the rotation axis L2. The second reset member 23 can be set as a compression spring, rubber, sponge, or a tension spring, etc. Preferably, the second reset member 23 is a compression spring with one end abutted against the pressing member 24 and the other end abutted against the driving force receiving member 21 or the driving force transmission member 22.

[0098] In some embodiments, the pressing portion 242 is arranged as a cone. When measured along a direction perpendicular to the rotation axis L2, the distance from the outer surface of the pressing portion 242 to the rotation axis L2 gradually decreases from front to back. Overall, the pressing portion 242 is formed into a horn shape with a gradually increasing size from back to front.

[0099] The acting member 214 in this embodiment still has a pressing force receiving surface 215. Different from the first embodiment, the pressing force receiving surface 215 in this embodiment is arranged such that at least a part of it faces the rotation axis L2, as Figure 7B shown. As the driving force receiving component 2 moves forward, the pressing portion 242 begins to abut against the abutting end surface 415 and moves backward. The second reset member 23 undergoes elastic deformation and stores elastic force. The outer surface of the pressing portion 242 gradually begins to press the pressing force receiving surface 215, causing the acting member 214 to move in a direction away from the rotation axis L2. The connecting member 213 swings around the end where it is connected to the box-side driving main body 211 until the acting member 214 enters the strip-shaped groove 412, and the driving force output surface 413 faces the driving force receiving surface 216. At this time, at least a part of the acting member 214 extends beyond the circumferential surface of the box-side driving main body 211, and the box-side driving main body 211 enters the engaging cavity 414.

[0100] When the driving force receiving component 2 moves backward, the second reset member 23 releases the elastic force, causing the pressing member 24 to tend to move forward, and the acting member 214 is gradually no longer pressed and resets in a direction closer to the rotation axis L2.

[0101] In some embodiments, the driving force receiving component 2 further includes a guiding portion 218 disposed in the movable cavity 212. The movement of the pressing member 24 in the front-rear direction is guided by the guiding portion 218. Specifically, the guiding portion 218 can be formed as a rod-shaped body or a groove-shaped body.

[0102] In some embodiments, the structure of the pressing member 24 can also be simplified to only have a pressing portion 242, as long as the pressing portion 242 is abutted by the abutting end face 415 and forces the acting member 214 to move in a direction away from the rotation axis L2.

[0103] [Embodiment III]

[0104] Figure 8A is a perspective view of the driving force receiving component related to Embodiment III of the present invention before being combined with the driving force output member; Figure 8B is a side view of the driving force receiving component related to Embodiment III of the present invention when observed along a direction perpendicular to the rotation axis of the driving force receiving component before being combined with the driving force output member; Figure 9A is a perspective view of the driving force receiving component related to Embodiment III of the present invention after being combined with the driving force output member; Figure 9B is a side view of the driving force receiving component related to Embodiment III of the present invention when observed along a direction perpendicular to the rotation axis of the driving force receiving component after being combined with the driving force output member.

[0105] Different from the above embodiments, the connecting member 213 in this embodiment is formed separately from the connecting member main body 211 on the box side. However, the same as the above embodiments, the connecting member 213 in this embodiment is arranged to be rotatable / swingable about an axis L21 intersecting the rotation axis L2, and the acting member 214 connected to the connecting member 213 can move between a close position close to the rotation axis L2 and a far position away from the rotation axis L2 as the connecting member 213 rotates / swings.

[0106] Such as Figure 8AAs shown, the connecting member 213 includes an intermediate portion 213a, a deformation portion 213b, a connecting portion 213c, and a force-receiving portion 213d. Among them, the deformation portion 213b and the connecting portion 213c are both connected to the intermediate portion 213a, and the force-receiving portion 213d is connected to the deformation portion 213b, and the two can be integrally formed. The acting member 214 is connected to the connecting portion 213c. The connecting member 213 is rotatably connected to the box-side driving main body 211 through the intermediate portion 213a, and the connection between the two can be achieved by means of shaft-hole fitting, pin connection, etc. The deformation portion 213b and the intermediate portion 213a can be integrally formed or separately formed. Preferably, the deformation portion 213b is an elastic arm connected to the intermediate portion 213a. The force-receiving portion 213d is used to abut against the end portion 416 of the device-side driving main body 411 to cause the deformation portion 213b to undergo elastic deformation. At the same time, the connecting member 213 rotates around the rotation axis L21, and the acting member 214 moves from the close position close to the rotation axis L2 to the far position away from the rotation axis L2. Therefore, the size of the force-receiving portion 213d needs to meet the requirement that along the rotation direction r2 / r4, the arc length of the force-receiving portion 213d is greater than the arc length of the strip-shaped groove 412.

[0107] Furthermore, the driving force receiving assembly 2 further includes a limiting groove 221, and at least a part of the deformation portion 213b is received in the limiting groove 221. The limiting groove 221 can be provided in either the driving force receiving member 21 or the driving force transmitting member 22. Through this structure, on the one hand, the possible displacement of the deformation portion 213b is suppressed, and on the other hand, the driving force received by the acting member 214 can also be transmitted to the driving force receiving member 21 or the driving force transmitting member 22 through the deformation portion 213b, the wear of the acting member 214 can be reduced, and the transmission of the driving force is more efficient.

[0108] Preferably in this embodiment, when the driving force receiving member 21 starts to be combined with the driving force output member 4, along the radial direction of the driving force receiving member 21, the acting member 214 is in a state of not exceeding the circumferential surface of the box-side driving main body 211. Along the rotation axis L2, if the acting member 214 is not aligned with the strip-shaped groove 412, then the acting member 214 will enter the combining cavity 414 together with the box-side driving main body 211. As the driving force receiving member 21 continues to move forward, the end portion 416 starts to abut against the force-receiving portion 213d, and the deformation portion 213b starts to undergo elastic deformation. However, due to the acting member 214 being restricted by the inner wall of the device-side driving main body 411, the elastic deformation amount of the deformation portion 213b is limited.

[0109] As the driving force output member 4 rotates, the acting member 214 aligns with the strip-shaped groove 412. The rotation of the connecting member 213 will no longer be restricted, and the deformation portion 213b further undergoes elastic deformation. The acting member 214 enters the strip-shaped groove 412. Along the rotation direction r2 / r4, the driving force output surface 413 faces the driving force receiving surface 216, and the driving force can be transmitted from the driving force output member 4 to the driving force receiving member 21.

[0110] [Embodiment 4]

[0111] Figure 10 is a perspective view before the combination of the driving force receiving assembly and the driving force output member according to Embodiment 4 of the present invention; Figure 11A is a perspective view during the combination process of the driving force receiving assembly and the driving force output member according to Embodiment 4 of the present invention; Figure 11B is a perspective view after the combination of the driving force receiving assembly and the driving force output member according to Embodiment 4 of the present invention.

[0112] In the above embodiment, the connecting member 213 is arranged to rotate or swing, and the movement track of the acting member 214 will present an arc. In this embodiment, the movement track of the acting member 214 is a straight line.

[0113] As Figure 10 shown, the connecting member 213 and the acting member 214 are integrally formed. The acting member 214 is slidably arranged in the sliding groove 219 on the box-side driving main body 211. The sliding groove 219 can be either through or non-through in the direction intersecting the front-rear direction, as long as it does not affect the sliding of the acting member 214 in the sliding groove 219.

[0114] Furthermore, the driving force receiving assembly 2 further includes the above-mentioned pressing member 24 and the second reset member 23. The second reset member 23 is used to make the pressing member 24 have a tendency to move forward. Under the supporting action of the pressing member 24, at least a part of the acting member 214 protrudes from the circumferential surface of the box-side driving main body 211.

[0115] When the driving force receiving member 21 and the driving force output member 4 start to combine, along the rotation axis L2, if the acting member 214 aligns with the strip-shaped groove 412, as the box-side driving main body 211 enters the combination cavity 414, the acting member 214 will directly enter the strip-shaped groove 412. Along the rotation direction r2 / r4, the driving force output surface 413 faces the driving force receiving surface 216, and the driving force output member 4 can output the driving force to the driving force receiving member 21.

[0116] Along the rotation axis L2, if the acting member 214 does not align with the strip-shaped groove 412, as Figure 11AAs shown, by abutting the guiding surface 217 against the end portion 416 of the device-side driving main body 411, the acting member 214 / connecting member 213 moves from the far position away from the rotation axis L2 towards the near position close to the rotation axis L2. Eventually, the acting member 214 and the cartridge-side driving main body 211 enter the engaging cavity 414 together. The inner surface of the device-side driving main body 411 presses the acting member 214. At the same time, the acting member 214 / connecting member 213 presses the pressing member 24, forcing the second reset member 23 to elastically deform, and the pressing member 24 moves backward.

[0117] As the driving force output member 4 rotates, along the radial direction of the driving force receiving member 21 / driving force output member 4, the acting member 214 is aligned with the strip-shaped groove 412. The second reset member 23 releases the elastic force, and the acting member 214 protrudes from the cartridge-side driving main body 211 again. Along the rotation direction r2 / r4, the driving force receiving surface 216 faces the driving force output surface 413, and the driving force output member 4 can output the driving force to the driving force receiving member 21.

[0118] [Embodiment Five]

[0119] Figure 12 is an exploded view of the components of the driving force receiving assembly according to Embodiment Five of the present utility model; Figure 13A is a perspective view of the driving force receiving assembly and the driving force output member before combination according to Embodiment Five of the present utility model; Figure 13B is along Figure 13A a side view when observing the driving force receiving assembly along the rotation axis; Figure 14A is a perspective view of the driving force receiving assembly and the driving force output member after combination according to Embodiment Five of the present utility model; Figure 14B is along Figure 14A a side view when observing the driving force receiving assembly along the rotation axis.

[0120] In this embodiment, the connecting member 213 is arranged to be rotatable about the rotation axis L21. As Figure 12 shown, the connecting member 213 includes an intermediate portion 213a, a force-receiving portion 213d, and a connecting portion 213c. The acting member 214 is connected to the connecting member 213. Similarly, the connecting portion 213c can be regarded as the acting member 214. The connecting pin 25 passes through the intermediate portion 213a and enters the connecting hole 211c located on the cartridge-side driving main body 211. In this way, the connecting member 213 and the cartridge-side driving main body 211 are rotatably connected; overall, the connecting member 213 is formed in a V shape; when two connecting members 213 are provided, the connecting pin 25 passes through the two connecting members 213 simultaneously.

[0121] The driving force receiving component 2 in this embodiment also includes an extrusion member 24. However, the extrusion member 24 in this embodiment is no longer arranged in the movable cavity 212, but is arranged outside the box-side driving main body 211. As shown in the figure, the extrusion member 24 is a circular ring sleeved outside the box-side driving main body 211. Preferably, the extrusion member 24 is coaxially arranged with the box-side driving main body 211.

[0122] Furthermore, the driving force receiving component 2 further includes a limiting portion 211d arranged on the box-side driving main body 211. The limiting portion 211d is used to position the initial position of the connecting member 213 / acting member 214. Preferably, the limiting portion 211d is a protrusion with an inclined surface arranged in the movable cavity 212.

[0123] As Figure 13A and Figure 13B shown, before the driving force receiving member 21 starts to engage with the driving force output member 4, the extrusion member 24 is located between the force receiving portion 213d and the connecting portion 213c / acting member 214. The acting member 214 is supported by the limiting portion 211d and is positioned at the initial position. Along the front-back direction, the connecting portion 213c / acting member 214, the extrusion member 24, and the force receiving portion 213d are arranged in sequence from front to back. Along the radial direction of the driving force receiving member 21, the connecting portion 213c / acting member 214 does not extend beyond the circumferential surface of the box-side driving main body 211.

[0124] As the device-side driving main body 211 enters the engaging cavity 414, the extrusion member 24 is abutted by the end portion 416 and moves backward. At the same time, the extrusion member 24 also pushes the force receiving portion 213d, causing the connecting member 213 to rotate around the rotation axis L21. The connecting portion 213c / acting member 214 gradually extends beyond the box-side driving main body 211. After the extrusion member 214 enters the strip-shaped groove 412, along the rotation direction r2 / r4, the driving force output surface 413 and the driving force receiving surface 216 face each other, and the driving force output member 4 can output driving force to the driving force receiving member 21.

[0125] Preferably, the driving force receiving component 2 can also be provided with a second resetting member that abuts against the extrusion member 24. When the driving force receiving member 21 engages with the driving force output member 4, the second resetting member undergoes elastic deformation. During the process of the driving force receiving member 21 disengaging from the driving force output member 4, the second resetting member releases elastic force, forcing the extrusion member 24 to return to the position between the force receiving portion 213d and the connecting portion 213c / acting member 214. Furthermore, the extrusion member 24 pushes the connecting portion 213c / acting member 214 back to the initial position.

[0126] [Embodiment Six]

[0127] Figure 15 is a perspective view before the driving force receiving component and the driving force output member involved in the sixth embodiment of the present invention are combined; Figure 16It is a perspective view of the combination of the driving force receiving component and the driving force output member involved in Embodiment VI of the present utility model.

[0128] Similar to Embodiment IV, the connecting member 213 / acting member 214 in this embodiment is also arranged to be slidable along a straight line along the sliding groove 219 provided on the box side driving main body 211. The difference is that before the driving force receiving member 21 and the driving force output member 4 start to be combined, the acting member 214 is in a close position close to the rotation axis L2. Preferably, at this time, along the radial direction of the driving force receiving member 21, the driving force acting member 214 does not extend beyond the circumferential surface of the box side driving main body 211.

[0129] Furthermore, the driving force receiving component 2 in this embodiment further includes a force applying member 27 that forces the pressing member 24 to move forward. In practice, the force applying member 27 can apply a thrust force or a pulling force to the pressing member 24. As Figure 15 and Figure 16 shown, the force applying member 27 includes a pushed portion 271, an extending portion 272, and a force applying portion 273. Among them, the extending portion 272 extends in the front-rear direction. The pushed portion 271 is used to receive the thrust of the cover door 102. The force applying portion 273 is used to apply a thrust force or a pulling force to the pressing member 24. The extending portion 272 can be arranged either inside the box main body 1 or outside the box main body 1. When observing along a direction intersecting the front-rear direction, at least a part (such as the extending portion 272) of the force applying member 27 overlaps with the box main body 1.

[0130] During the forward movement of the pressing member 24, it pushes the acting member 214 to move along the sliding groove 219 from the close position to the far position. At least a part of the acting member 214 gradually extends beyond the circumferential surface of the box side driving main body 211. When the acting member 214 enters the strip-shaped groove 412, along the rotation direction r2 / r4, the driving force output surface 413 and the driving force receiving surface 216 are opposite, and the driving force output member 4 can output a driving force to the driving force receiving member 21.

[0131] Furthermore, the driving force receiving component 2 further includes the second reset member 23. When the pushed portion 271 is pushed by the cover door 102, the second reset member 23 undergoes elastic deformation. When the cover door 102 is opened, the second reset member 23 releases the elastic force, and the force applying member 27 and the pressing member 24 are reset. Specifically, the second reset member 23 can be connected to the force applying member 27 or the pressing member 24, as long as the second reset member 23 can achieve the above reset function.

[0132] [Embodiment VII]

[0133] Figure 17 It is an exploded schematic diagram of the components of the driving force receiving component involved in Embodiment VII of the present utility model; Figure 18AIt is a perspective view of the process of the driving force receiving component and the driving force output member being combined in Embodiment 7 of the present utility model; Figure 18B It is a perspective view of the driving force receiving component and the driving force output member being combined in Embodiment 7 of the present utility model after completion.

[0134] Different from Embodiment 4 and Embodiment 6, in this embodiment, the connecting member 213 / acting member 214 is arranged to move in a direction parallel to the front-rear direction, such as Figure 17 shown, the connecting member 213 includes an intermediate portion 213a, a connecting portion 213c and a force-receiving portion 213d. Both the connecting portion 213c and the force-receiving portion 213d are connected to the intermediate portion 213a. The acting member 214 is connected to the connecting portion 213c, and the force-receiving portion 213d is also connected to the connecting portion 213c. Preferably, the acting member 214, the force-receiving portion 213d and the connecting portion 213c are integrally formed. The intermediate portion 213a is formed as a guide rod / guide groove / guide hole, etc. that can guide the connecting member 213 to move in the front-rear direction.

[0135] The driving force receiving component 2 involved in this embodiment also includes the above-mentioned second reset member 23. One end of the second reset member 23 is connected to the connecting member 213, and the other end is connected to the box-side driving main body 211, and is used to force the connecting member 213 to have a tendency to move forward.

[0136] Before the driving force receiving member 21 and the driving force output member 4 are combined and after the driving force receiving member 21 and the driving force output member 4 are combined, along the radial direction of the driving force receiving member 21, at least a part of the connecting member 213 / acting member 214 extends beyond the circumferential surface of the box-side driving main body 211.

[0137] Such as Figure 18A and Figure 18B shown, during the process of the driving force receiving member 21 and the driving force output member 4 being combined, the box-side driving main body 211 enters the combining cavity 414. Along the front-rear direction / the direction extending along the rotation axis L2, when the acting member 214 is aligned with the strip-shaped groove 412, the acting member 214 will directly enter the strip-shaped groove 412, so that the driving force output surface 413 and the driving force receiving surface 216 face each other along the rotation direction r2 / r4, and the driving force output member 4 can output a driving force to the driving force receiving member 21.

[0138] In the direction extending along the front-rear direction / rotation axis L2, when the acting member 214 is misaligned with the strip-shaped groove 412, the acting member 214 / the force-receiving portion 213d will abut against the end portion 416, causing the acting member 214 to move backward. At the same time, the second reset member 23 undergoes elastic deformation. As the driving force output member 4 rotates around the rotation axis L4, the acting member 214 gradually aligns with the strip-shaped groove. The second reset member 23 releases the elastic force, and the acting member 214 enters the strip-shaped groove 412, causing the driving force output surface 413 and the driving force receiving surface 216 to face each other along the rotation direction r2 / r4. The driving force output member 4 can output the driving force to the driving force receiving member 21.

[0139] [Embodiment VIII]

[0140] Figure 19 It is a three-dimensional view after the combination of the driving force receiving assembly and the driving force output member involved in Embodiment VIII of the present utility model.

[0141] In the above embodiment, when the driving force receiving member 21 is combined with the driving force output member 4, the box-side driving main body 211 enters the combination cavity 414. However, in this embodiment, the diameter of the movable cavity 212 located radially inside the box-side driving main body 211 is enlarged, and the equipment-side driving main body 411 realizes the combination of the driving force receiving member 21 and the driving force output member 4 by entering the movable cavity 212. However, it can be realized that the equipment-side driving main body 411 in the above embodiments can also be arranged to enter the movable cavity 212, thereby realizing the combination of the driving force receiving member 21 and the driving force output member 4.

[0142] As Figure 19 shown, the connecting member 213 is arranged in a cantilever shape, and the acting member 214 is connected to the connecting member 213. Since the rotation axis L2 and the rotation axis L4 are coaxial, along the radial direction of the driving force receiving member 21 / the radial direction of the driving force output member 4, the distance from the end of the acting member 214 facing the rotation axis L2 to the rotation axis L2 is less than the distance from the circumferential surface of the equipment-side driving main body 411 to the rotation axis L4.

[0143] During the combination of the driving force receiving member 21 and the driving force output member 4, along the rotation axis L2, when the acting member 214 is aligned with the strip-shaped groove 412, the acting member 214 can directly enter the strip-shaped groove 412. Along the rotation direction r2 / r4, the driving force output surface 413 and the driving force receiving surface 216 face each other, and the driving force output member 4 can output the driving force to the driving force receiving member 21.

[0144] Along the rotation axis L2, when the acting member 214 is misaligned with the strip-shaped groove 412, the acting member 214 is squeezed by the end portion 416 and moves from the close position towards the far position. Subsequently, the acting member 214 faces the circumferential surface of the device-side driving main body 411. At this time, the acting member 214 is squeezed by the device-side driving main body 411 and held in the far position. As the driving force output member 4 rotates, along the radial direction of the driving force output member 4, the acting member 214 gradually faces the strip-shaped groove 412 and enters the strip-shaped groove 412. Along the rotation direction r2 / r4, the driving force output surface 413 and the driving force receiving surface 216 face each other, and the driving force output member 4 can output the driving force to the driving force receiving member 21. It can be seen that in this embodiment, when the acting member 214 is in the close position, as the driving force output member 4 rotates, the driving force is transmitted from the driving force output member 4 to the driving force receiving member 21. When the acting member 214 is in the far position, the driving force cannot be transmitted from the driving force output member 4 to the driving force receiving member 21.

[0145] [Embodiment Nine]

[0146] Figure 20 is an exploded view of the components of the driving force receiving assembly according to Embodiment Nine of the present utility model; Figure 21 is a perspective view of the driving force receiving assembly and the driving force output member combined and completed according to Embodiment Nine of the present utility model.

[0147] Different from the above embodiment, the driving force receiving member 21 in this embodiment is arranged to be movable relative to the driving force transmission member 22. As Figure 20 shown, the driving force receiving member 21 and the driving force transmission member 22 are formed separately. The driving force receiving member 21 includes a box-side driving main body 211, a connecting member 213, and an acting member 214. Among them, the connecting member 213 is connected to the box-side driving main body 211, and the acting member 214 is connected to the connecting member 213. Preferably, the connecting member 213 is connected to the box-side driving main body 211 in the form of a cantilever. Before the driving force receiving member 21 is combined with the driving force output member 4, the acting member 214 is in a close position close to the rotation axis L2.

[0148] Furthermore, the driving force receiving assembly 2 in this embodiment further includes a squeezing member 24, and the squeezing member 24 is used to squeeze the acting member 214 from the close position towards the far position. Preferably, the squeezing member 24 is fixedly connected to the driving force transmission member 22. More preferably, the squeezing member 24 is integrally formed with the driving force transmission member 22; the squeezing member 24 also has a conical squeezing portion 242.

[0149] Similarly, when the driving force receiving member 21 starts to engage with the driving force output member 4, along the rotation axis L2, when the acting member 214 aligns with the strip groove 412, the acting member 214 will directly enter the strip groove 412. At the same time, the driving force receiving member 21 is abutted by the abutting end face 415 and moves in the direction closer to the driving force transmitting member 22. During this process, the pressing portion 242 presses the acting member 214, causing the acting member 214 to gradually move from the close position to the far position. Finally, along the rotation direction r2 / r4, the driving force output surface 413 faces the driving force receiving surface 216, and the driving force output member 4 can output the driving force to the driving force receiving member 21.

[0150] Along the rotation axis L2, when the acting member 214 does not align with the strip groove 412, the acting member 214 will enter the engaging cavity 414 together with the cartridge side driving main body 211. As the cartridge continues to be installed, the cartridge side driving main body 211 is abutted by the abutting end face 415 and moves from the close position to the far position. The pressing force receiving surface 215 of the acting member 214 is pressed by the inner wall of the device side driving main body 411, or the pressing force receiving surface 215 is restricted by the inner wall of the device side driving main body 411. As the driving force output member 4 rotates, along the radial direction of the driving force receiving member 21 / the radial direction of the driving force output member 4, the acting member 214 faces the strip groove 412. Therefore, the acting member 214 moves from the close position to the far position. Finally, along the rotation direction r2 / r4, the driving force output surface 413 faces the driving force receiving surface 216, and the driving force output member 4 can output the driving force to the driving force receiving member 21.

[0151] Furthermore, the driving force receiving assembly 2 involved in this embodiment further includes a second reset member 23 disposed between the driving force receiving member 21 and the driving force transmitting member 22. When the driving force receiving member 21 is abutted by the abutting end face 415, the second reset member 23 undergoes elastic deformation. When the driving force transmitting member 22 moves backward with the cartridge body 1, the second reset member 23 releases the elastic force, forcing the driving force receiving member 21 and the driving force output member 22 to move away from each other, and the acting member 214 moves from the far position to the close position.

[0152] In some embodiments, the second reset member 23 may not be provided. During the process of the driving force transmitting member 22 moving backward with the cartridge body 1, the driving force receiving member 21 and the driving force output member 22 can still move away from each other. Under the elastic action of the connecting member 213 itself, the acting member 214 moves from the far position to the close position.

[0153] In some embodiments, the driving force between the driving force receiving member 21 and the driving force transmitting member 22 can be transmitted through a pin connection, or the driving force receiving member 21 and the driving force transmitting member 22 can be in surface contact to directly transmit the driving force.

[0154] [Embodiment Ten]

[0155] Figure 22 is a perspective view of the driving force receiving assembly and the driving force output member before combination in Embodiment Ten of the present utility model; Figure 23 is a perspective view of the driving force receiving assembly and the driving force output member after combination in Embodiment Ten of the present utility model.

[0156] In this embodiment, the connecting member 213 is arranged to be movable relative to the cartridge side driving main body 211. As Figure 22 shown, the connecting member 213 is connected to the cartridge side driving main body 211 in the form of a cantilever. The acting member 214 is connected to the connecting member 213. The acting member 214 has a squeezing force receiving surface 215, a driving force receiving surface 216, and a guiding surface 217. When the squeezing force receiving surface 215 receives a squeezing force towards the rotation axis L2, the acting member 214 moves from the far position towards the near position. When the squeezing force receiving surface 215 is no longer squeezed, the acting member 214 returns from the near position to the far position.

[0157] In some embodiments, along the radial direction of the driving force receiving member 21, the distance from the squeezing force receiving surface 215 to the rotation axis L2 is greater than the distance from the inner wall of the device side driving main body 411 to the rotation axis L4. Thus, during the combination process of the driving force receiving member 21 and the driving force output member 4, along the front-back direction, when the acting member 214 is aligned with the strip-shaped groove 412, the acting member 214 directly enters the strip-shaped groove 214. Along the rotation direction r2 / r4, the driving force output surface 413 is opposite to the driving force receiving surface 216, and the driving force can be transmitted from the driving force output member 4 towards the driving force receiving member 21.

[0158] Along the front-back direction, when the acting member 214 is not aligned with the strip-shaped groove 412, the guiding surface 217 abuts against the end portion 416 to force the connecting member 213 to move relative to the cartridge side driving main body 211. The acting member 214 undergoes elastic deformation to store a restoring force and moves from the far position towards the near position. When the acting member 214 enters the combination cavity 414, the squeezing force receiving surface 215 is squeezed by the inner wall of the device side driving main body 411 to keep the acting member 214 in the near position; as the driving force output member 4 rotates, along the radial direction of the driving force receiving member 21 / the radial direction of the driving force output member 4, the acting member 214 is opposite to the strip-shaped groove 412, the connecting member 213 moves relative to the cartridge side driving main body 211 again, the acting member 214 releases the restoring force, moves from the near position towards the far position, and enters the strip-shaped groove 412. Along the rotation direction r2 / r4, the driving force output surface 413 is opposite to the driving force receiving surface 216, and the driving force can be transmitted from the driving force output member 4 towards the driving force receiving member 21.

[0159] In some embodiments, before the driving force receiving member 21 is combined with the driving force output member 4, the acting member 214 can also be in the close position. Then, during the combination of the driving force receiving member 21 and the driving force output member 4, whether the acting member 214 is aligned with the strip-shaped groove 412 or not, the acting member 214 can smoothly enter the combination cavity 414.

[0160] As the cartridge continues to be installed, the acting member 214 begins to abut against the abutting end face 415 and undergoes elastic deformation. The acting member 214 gradually moves from the close position towards the far position. If the acting member 214 is aligned with the strip-shaped groove 412, then the acting member 214 will directly enter the strip-shaped groove 412. If the acting member 214 is not aligned with the strip-shaped groove 412, then the extrusion force receiving surface 215 will be extruded by the inner wall of the device-side driving main body 411. As the driving force output member 4 rotates (the angle range is 0° - 180°), along the radial direction of the driving force receiving member 21 / the radial direction of the driving force output member 4, the acting member 214 is opposite to the strip-shaped groove 412, and the acting member 214 enters the strip-shaped groove 412; as the driving force receiving member 21 is separated from the driving force output member 4, the acting member 214 no longer abuts against the abutting end face 415, and the acting member 214 begins to gradually return from the far position to the close position. Thus, the acting member 214 can smoothly escape from the combination cavity 414.

[0161] As described above, in Embodiment 1, Embodiment 3, Embodiment 8, Embodiment 9, and Embodiment 10, the driving force receiving assembly 2 does not need to be additionally provided with a second reset member 23, but rather uses the elastic action of the connecting member 213 itself to enable the acting member 214 to move between the close position and the far position.

[0162] Based on the inventive concept of the present utility model, when the driving force receiving assembly 2 is linked with the shutter assembly 3, all the above embodiments do not need the second reset member 23. At this time, the reset of each component in the driving force receiving assembly 2 can be achieved by using the reset force provided by the first reset member 34 provided in the shutter assembly 3. Thus, the structure of the driving force receiving assembly 2 can be further simplified.
