The clutch pushing assembly 240 is used for performing a pushing operation of the drive connection assembly 230.

Referring to fig. 2, 3 and 10, in some embodiments, the clutch urging assembly 240 may include an urging sleeve 241 and a push rod 242; wherein, the pushing sleeve 241 is connected to the transmission connection assembly 230, and the pushing rod 242 is used for pushing the pushing sleeve 41, so as to push the transmission connection assembly 230, so that the transmission connection assembly 230 can smoothly perform connection and disconnection operations with the first transmission assembly 210.

The clutch device 200 provided in the embodiment of the application is connected between a driving mechanism of a door opening and closing device and a door opening and closing executing mechanism connected with a door body, and connection between the driving mechanism and the door opening and closing executing mechanism is established or cut off, so that the problem that the door opening and closing device of electrical equipment is easy to interfere with a manually operated door body is solved. Specifically, a first transmission assembly 210 and a second transmission assembly 220 are respectively provided, and are used for respectively connecting a driving mechanism and a door opening and closing mechanism, and a transmission connecting assembly 230 connected with the second transmission assembly 220 is provided and detachably connected to the first transmission assembly 210, so that the first transmission assembly 210 and the second transmission assembly 220 are detachably connected, and the clutch operation between the driving mechanism and the door opening and closing executing mechanism is convenient to implement; and the pushing sleeve 241 connected to the transmission connection assembly 230 is pushed by the pushing rod 242 to stably push the first transmission assembly 210 to be separated from or connected with the transmission connection assembly 230, so that the first transmission assembly 210 and the second transmission assembly 220 can be stably separated from or connected with each other in a working state, and the convenience, smoothness and safety of door operation of electrical equipment are improved.

Referring to fig. 7, in some embodiments, the drive connection assembly 230 may be configured as a drive connection member having a connection end 231 and a pushing end 232, and connected to the pushing sleeve 241 by the pushing end 232, so that the drive connection member is pushed to move by the pushing sleeve 241, so that the connection end 231 can be detachably connected to the first drive assembly 210, thereby connecting or disconnecting the first drive assembly 210.

In some embodiments, the transmission connection assembly 230 may be integrally disposed with the second transmission assembly 220 or fixed to the second transmission assembly 220, so that the second transmission assembly 220 moves integrally, thereby enabling connection and disconnection with the first transmission assembly 210, and simplifying the molding and assembling operations of the assembly.

In some embodiments, the connection end 231 may be movably disposed on the second transmission assembly 220 such that the connection end 231 can move relative to both the first transmission assembly 210 and the second transmission assembly 220, while the first transmission assembly 210 and the second transmission assembly 220 may be in a relatively stable position and posture, without having to create movement in a non-transmission operating direction, to facilitate a stable connection with upstream and downstream equipment, thereby maintaining a stable working state.

Referring to fig. 4 and fig. 5, in some embodiments, a clamping groove 211 may be formed on the first transmission assembly 210, and the connecting end 231 may be fastened by an adapter card, so that the operation that the connecting end 231 is separated from the clamping groove 211 can be smoothly implemented, and stability and reliability of the clutch operation are ensured.

Referring to fig. 5, in some embodiments, the first transmission assembly 210 may be configured as a first transmission gear 212 that transmits the driving force by way of a gear mesh transmission. In consideration of the operation mode of the gears rotating around their axes, the clamping grooves 211 may be provided on the axial end face of the first transmission gear 212, so that the connection state and disconnection state of the connection end 231 with the first transmission gear 212 are established, and the influence on the operation state of the rotation and tooth engagement thereof is reduced.

It should be noted that, for the working posture of the first transmission gear 212, the movement manner of the second transmission assembly 220 should be similar to the rotation manner of the first transmission gear 212 around a shaft, so as to realize synchronous rotation transmission.

Referring to fig. 6, in some embodiments, the second transmission assembly 220 may be provided with a second transmission gear 222, and the first transmission gear 212 and the second transmission gear 222 may be provided in a coaxial rotary configuration; the connection end 231 is disposed on the second transmission gear 222, and the connection end 231 is connected to the first transmission gear 212 by pushing the pushing end 232, so that the first transmission gear 212 and the second transmission gear 222 are connected and synchronously rotated, and a communicating driving force transmission path is established.

Referring to fig. 2, 3, 11, and 12, in some embodiments, in order to fulfill the rotation requirements of the first and second transmission gears 212 and 222, a rotation shaft structure may be provided on the base 900 to guide the first and second transmission gears 212 and 222 to be assembled and rotated. Specifically, a common rotating shaft 920 may be disposed on the base 900, and the first transmission gear 212 and the second transmission gear 222 are sleeved on the common rotating shaft 920 along the axial direction, so as to ensure the stable rotation function of the gears.

In some embodiments, the common rotation shaft 920 may be configured as a variable cross-section shaft, and a support column 921 and a rotation shaft column 922 sequentially arranged upward from the base 900, wherein the diameter of the support column 921 is greater than the diameter of a shaft hole formed in the second transmission gear 222, and the diameter of the rotation shaft column 922 may be adapted to the diameter of the shaft hole of the second transmission gear 222, so that the second transmission gear 222 may rest on the support column 921 and be sleeved on the rotation shaft column 922, so that the second transmission gear 222 is at a certain height from the base 900 and may stably rotate. The first transmission gear 212 may be stacked on the second transmission gear 222 and sleeved on the rotating shaft column 922 to realize rotation.

In some embodiments, the connection end 231 may be fixed on an axial end surface of the second transmission gear 222, and by pushing the pushing end 232, the second transmission gear 222 is pushed toward or away from the first transmission gear 212, so that the connection end 231 is engaged with the clamping groove 211 or disengaged from the clamping groove 211. The whole operation is simple, the forming of the structural member is relatively simple, and the assembly operation is simple and efficient.

Referring to fig. 6, in some embodiments, a hole 221 may be disposed on the second transmission gear 222, and the connection end 231 is movably embedded in the hole 221, so as to push the pushing end 232, so that the connection end 231 moves relative to the hole 221, approaches the first transmission gear 212, and is further snapped into the slot 211, and a connection between the first transmission gear 212 and the second transmission gear 222 is established. When the connection end 231 is disengaged from the clamping groove 211, the connection end 231 also moves relative to the clamping hole 221; during the process, the movement operation of the transmission connection member has a low influence on the positions and attitudes of the first transmission gear 212 and the second transmission gear 222, so that the positions and attitudes of the rotation of the transmission connection member are conveniently kept, and the working state and the operation reliability of the device are maintained.

In some embodiments, the clamping groove 211 may also be disposed to axially penetrate through the through hole of the first transmission gear 212, so that unnecessary disturbance caused by the connection end 231 directly pushing against the bottom of the clamping groove 211 can be avoided, and stability of the rotation process of the first transmission gear 212 is maintained.

In some embodiments, considering the rotation of the first transmission gear 212 and the second transmission gear 222, in order to increase the efficiency of the connection end 231 being snapped into the clamping groove 211, the connection end 231 may be provided with a plurality of connection arms 2311, and accordingly, the number of the clamping grooves 211 may be the same as or greater than the number of the connection arms 2311, so as to reduce the difficulty of the connection arms 2311 being snapped into the clamping grooves 211.

It should be noted that the rotation track of the card slot 211 should intersect with the movement track of the connection arm 2311, so that the connection arm 2311 may be inserted into the card slot 211.

In some embodiments, the distance from the connection arm 2311 to the rotation axis of the second transmission gear 222 and the distance from the clamping groove 211 to the rotation axis of the first transmission gear 212 should be consistent, so that the clamping groove 211 can be stably clamped and separated from the connection arm 2311 in the axis direction. Therefore, the pushing force to the pushing end 231 is along the axis direction of the rotating shaft of the second transmission gear 222, and the axis of the rotating shaft can be used as a reference during processing and assembling, so that the clutch pushing assembly 240 is convenient to set, assemble and push.

It should be noted that, the distance from the connection arm 2311 to the rotation axis of the second transmission gear 222 and the distance from the clamping groove 211 to the rotation axis of the first transmission gear 212 may also be inconsistent, only the rotation track of the clamping groove 211 should intersect with the movement track of the connection arm 2311, and when there are multiple connection arms 2311 and clamping grooves 211, the intervals between the multiple connection arms 2311 and the intervals between the multiple clamping grooves 211 are reasonably set to avoid the incapability of stable embedding.

In some embodiments, the plurality of connection arms 2311 may be equally spaced on a circular track, and correspondingly, the plurality of clamping grooves 211 may also be equally spaced on the circular track, so that a well-adapted position and spacing pattern can be formed, and clamping is facilitated.

It should be noted that, in order to increase the efficiency of the fitting between the connection arm 2311 and the card slot 211, the number of card slots 211 may be increased appropriately, and the number of card slots 211 may be set to be an integer multiple of the number of connection arms 2311, so that the efficiency of the fitting between the connection arm 2311 and the card slot 211 may be increased substantially when the card slots 211 and the connection arms are arranged at equal intervals.

In some embodiments, the plurality of connection arms 2311 may also be disposed on a plurality of circular tracks, and accordingly, an adapted number of the clamping grooves 211 should be disposed on the first transmission gear 212 with reference to the circular tracks to ensure stable engagement.

In some embodiments, the pushing end 232 of the transmission connection member is directly connected to the pushing sleeve 241, and the transmission connection member may be configured to rotate around the rotation axis of the second transmission gear 222 in consideration of the direction of pushing being perpendicular to the rotation directions of the second transmission gear 222 and the first transmission gear 212; the pushing end 232 is rotatably arranged on the pushing sleeve 241, so that the working state of rotation and axial movement of the transmission connecting piece can be considered.

The pushing end of the transmission connecting piece comprises an annular seat, and the annular seat is rotatably connected to the pushing sleeve 241, so that the working states of rotation and axial movement of the transmission connecting piece are realized. On the other hand, the pushing sleeve 241 only needs to axially push the annular seat, and the rotating state of the pushing sleeve is not needed to be considered, so that the structural arrangement and the installation configuration of the clutch pushing assembly 240 are greatly simplified.

It should be noted that, in order to reduce the interference of the moving operation of the transmission connection piece on the first transmission gear 212 and the second transmission gear 222, the ring seat may be disposed on a side of the second transmission gear 222 away from the first transmission gear 212, and the connection arm shaft 2311 passes through the second transmission gear 222 and may further move to be clamped into the clamping groove 211, so that the operation of pushing the ring seat may not extend between the two transmission gears, and may keep the two relatively stable.

Referring to fig. 8, in some embodiments, the pushing sleeve 241 is used as a pushing medium, a shaft sleeve portion 2412 and a pushing portion 2411 may be provided on the pushing sleeve 241, and the annular seat may be sleeved on the shaft sleeve portion 2412, so as to keep the rotatable state of the annular seat; accordingly, the pushing portion 2411 is configured to receive the pushing force of the pushing rod 242, so that the pushing sleeve 241 moves along the axis direction of the rotation shaft of the first transmission gear 212, thereby performing the pushing operation of the transmission connection member.

In some embodiments, the moving direction of the pushing sleeve 241 is the axial direction of the rotation shaft of the second transmission gear 222, and the moving direction of the pushing sleeve 241 is defined as the first direction for convenience of description. In order to reduce the overall thickness of the device and reduce the molding and assembly difficulty, the pushing sleeve 241 can be pushed by adopting a direction-changing pushing manner, that is, the pushing direction of the push rod 242 is not in the first direction, but a certain angle exists, so that the space occupation requirement in the first direction is reduced.

Referring to fig. 8, 9 and 10, a first pushing surface 2413 may be specifically provided on the pushing portion 2411, a second pushing surface 2421 may be provided on the push rod 242, the first pushing surface 2413 and the second pushing surface 2421 may contact and may slide relatively, and the first pushing surface 2413 may be disposed at an acute angle with respect to the first direction, so that the pushing sleeve 241 along the first direction may be implemented by pushing the first pushing surface 2413, and further, the transmission connection may be pushed toward the first transmission gear 222.

In some embodiments, to optimize the efficiency of the pushing operation, the angle between the first pushing surface 2413 and the first direction may be set in a range of 30 degrees to 60 degrees, for example, 30 degrees, 45 degrees, or 60 degrees.

In some embodiments, the angle between the pushing direction of the push rod 242 and the first direction can be controlled according to 90 degrees, so as to reduce the arrangement space required by the matching relationship between the push rod 242 and the transmission connecting piece as much as possible, and reduce the overall volume scale of the device.

Referring to fig. 9 and 10, in some embodiments, in order to balance the force applied by the pushing sleeve 241, the number of the first pushing surfaces 2413 may be two, and the corresponding pushing rods 242 are also provided with two pushing arms 2422, which correspondingly push the two first pushing surfaces 2413; thereby ensuring the stress uniformity of the pushing sleeve by a two-point force application mode. And two pushing arms 2422 can be connected to the same connecting part 2423, so that synchronous action is realized, the consistent force application is ensured, and the even stress of the pushing sleeve 241 is ensured. Correspondingly, the two pushing arms 2422 are respectively provided with a second pushing surface 2421.

In some embodiments, two first pushing surfaces 2413 may be disposed on opposite sides of the pushing sleeve 241, two pushing arms 2422 may be disposed in parallel, and a second pushing surface 2421 may be disposed on an end portion of the pushing arms 2422 away from the connecting portion 2423, so that the pushing operation may be performed by pushing the connecting portion 2423.

In some embodiments, the number of the first pushing surface 2413, the second pushing surface 2421 and the pushing arms 2422 may be more than two according to the specification of the pushing sleeve.

Referring to fig. 2 and 3, in order to perform the pushing operation of the push rod 242, a linear driver 243 may be connected to the push rod 242 to push the push rod 242 in the second direction or reset the push sleeve 241 to move in the first direction by the linear driver. When the linear actuator 243 is reset, the push rod 242 releases the push sleeve 241.

In some embodiments, the linear drive 243 may employ a linear drive assembly such as an electromagnetic push rod, a ball screw, or the like.

In some embodiments, the drive is provided as a gear motor, or a motor provided with a reduction gearbox, so that the output torque and the rotational speed can be reasonably controlled.

Referring to fig. 12, in some embodiments, in order to reduce impact vibrations between the push rod 242 and the base 900 and between the base 900 and the pushing sleeve 241, shock pads 244 may be provided between the base 900 and the push rod 242 and between the pushing sleeve 241 and the base 900.

In some embodiments, there is a tendency for circumferential rotation due to the axial friction of the annular seat against the ejection sleeve 241, which tends to affect engagement with the clutch ejection assembly 240. An anti-rotation mechanism 930 may be disposed on the base 900 and engaged in the pushing sleeve 241 along the first direction, for stopping the circumferential rotation of the pushing sleeve 241.

Referring to fig. 8 and 12, in some embodiments, the anti-rotation mechanism 930 may include an anti-rotation rib 931, and the anti-rotation rib 931 may slide relative to the pushing sleeve 241 in a first direction, so as to achieve both the effect of preventing the pushing sleeve 241 from rotating circumferentially and sliding in the first direction. Generally, the pushing sleeve 241 may be provided with an anti-rotation slot 2414 adapted to the anti-rotation rib 931, and the anti-rotation rib 931 may slide along a first direction.

A locking member 262 may be provided at the other end of the fastening through hole to lock the headed bolt. The locking member 262 may alternatively be a bolt or nut.

In some embodiments, the connecting member 261 may be configured as a connecting shaft, one end of the connecting shaft is fixed on the base 900, and the first transmission assembly 210, the second transmission assembly 220 and the pushing sleeve 241 are sleeved on the connecting shaft to limit the detachment along the radial direction of the connecting shaft; the stop 263 is configured as a baffle, and the baffle is fixedly arranged at the other end of the connecting shaft, so that axial limiting along the connecting shaft is realized, and the first transmission assembly 210, the second transmission assembly 220 and the pushing sleeve 241 are stopped to be separated along the axial direction.
