In order to realize the switching of the connection and disconnection states of the first transmission assembly 410 and the second transmission assembly 420, the clutch device 400 is further provided with a clutch pushing assembly 430 for pushing the first transmission assembly 410 and the second transmission assembly 420 to approach each other or to separate from each other. The first transmission assembly 410 and the second transmission assembly 420 can be respectively provided with a matching connection structure, so that the first transmission assembly 410 and the second transmission assembly 420 can be stably connected and conveniently separated.

In some embodiments, the clutch pushing assembly 430 is provided with a pushing sleeve 431 that can be sleeved on the second transmission assembly 420. During assembly, the second transmission assembly 420 is embedded in the push sleeve 431, so that the second transmission assembly 420 can be stably fixed, and meanwhile, the second transmission assembly 420 can be indirectly pushed to move by pushing the push sleeve 431, so that the second transmission assembly 420 is prevented from being directly contacted, and the operating state of the second transmission assembly 420 is prevented from being influenced; ensuring the structural stability of the second transmission assembly 420 may also be achieved by pushing the second transmission assembly 420 in its entirety.

The clutch pushing assembly 430 is further provided with a push rod 432 for matching with and pushing the pushing sleeve 431, the pushing sleeve 431 is moved along the first direction through the push rod 432, the second transmission assembly 420 is integrally pushed to be close to the first transmission assembly 410, and connection is established; or by operating the push rod 432, the push sleeve 431 is caused to move in the reverse direction of the first direction, so that the second transmission assembly 420 is away from the first transmission assembly 410, and the connection is disconnected.

Referring to fig. 2, in some embodiments, the second transmission assembly 420 is provided with a first transmission member 421, which is in transmission connection with the first transmission assembly 410. A connecting end 4211 can be arranged on the first transmission piece 421 for connecting the first transmission assembly 410; the first transmission member 421 may further be provided with a pushing end 4212 for being embedded in the pushing sleeve 431, thereby forming a stable fixing structure. Accordingly, the connection end 4211 may protrude from the push sleeve 431, so as to ensure that the connection end 4211 is smoothly connected with the first transmission assembly 410.

Referring to fig. 5, 6, 7 and 8, in some embodiments, in order to improve the smoothness and convenience of connection and separation of the first transmission assembly 410 and the connection end 4211, a slot 411 capable of accommodating the connection end 4211 in a matching manner may be formed in the first transmission assembly 410, and the shape of the slot 411 may be set to a structural shape of engaging with the connection end 4211 in a matching manner, so that a connection transmission engagement state with stable connection can be established through a one-way pushing operation and a convenient engaging process, and the reliability of the transmission state is ensured; meanwhile, when the connection is disconnected, the connection can be quickly and smoothly separated through convenient one-way pushing, and the influence on the state and the structural stability of the first transmission piece 421 and the first transmission assembly 410 can be reduced.

In some embodiments, internal teeth 413 may be provided on a groove wall surface of the catching groove 411 based on one-way approaching and departing engagement and separation operations, and external teeth 4215 may be provided on an outer circumferential surface of the coupling end 4211 in cooperation, and engagement and disengagement of the internal teeth 413 and the external teeth 4215 are achieved as the first transmission member 421 moves.

In some embodiments, in order to meet the meshing requirement of the first transmission member 421 in a rotating state under some working conditions, a gap between two adjacent internal teeth 413 in the slot 411 may be set to be larger than a width of the external teeth 4215, so that a sufficient accommodation space is provided to facilitate the engagement of the external teeth 4215 in place, so as to efficiently establish a meshing connection state.

In some embodiments, the gap between adjacent two inner teeth 413 may be set to more than twice the width of the outer teeth 4215.

In some embodiments, the gap between two adjacent external teeth 4215 on the outer peripheral surface of the connection end 4211 may also be set to be larger than the width of the internal teeth 413, so that a sufficiently large accommodation space is provided for the internal teeth 413 to be fitted in place to efficiently establish the meshing connection state.

In some embodiments, the gap between adjacent two outer teeth 4215 may be set to more than twice the width of the inner teeth 413.

In some embodiments, the first transmission assembly 410 may be engaged to establish a transmission relationship with other structures, and the first transmission assembly 410 may be configured as a first transmission gear, and accordingly, the locking slot 411 may be opened at an axial end of the first transmission gear. The first transmission member 421 moves along the axial direction of the first transmission gear to realize connection and disconnection.

In some embodiments, in order to adapt to the working state of rotation of the first transmission gear, the locking slots 411 may be provided as circular slots, and the internal teeth 413 may be arranged on the wall surface of the circular slots at equal intervals, and the number is at least two; the number of the teeth 413 can be set to six or eight, and the specific number can be set according to the specification of the card slot 411. In cooperation, the outer shape surface of the connecting end 4211 can also be set to be circular, and the outer teeth 4215 can be arranged on the wall surface of a circular groove at equal intervals, and the number of the outer teeth is at least two; the number of teeth 413 can also be set to six, eight; the specific number may be the same as the number of the internal teeth 413.

The central shaft hole 412 of the first transmission gear and the circular clamping groove 411 are coaxially arranged, and meshing efficiency and stability of the inner teeth 413 are guaranteed. An extension cylinder 414 may be coaxially disposed at the opening of the central shaft hole 412 to facilitate stable fixation to the base 600 in cooperation with the embedded rotation shaft.

In some embodiments, since the pushing end 4212 is embedded in the pushing sleeve 431, when the first transmission member 421 rotates, the rotation posture is easily unstable due to the excessively large contact surface, and the abrasion amount is excessively large, a plurality of spacing bosses 4216 arranged at intervals may be arranged on the outer circumferential surface, so as to space the inner surface of the pushing sleeve 431 and the outer circumferential surface of the pushing end 4212 apart from each other, leaving a certain uniform gap, greatly reducing the contact area, reducing the abrasion degree, and ensuring the stability of the rotation posture of the first transmission member 421.

In some embodiments, the stop boss 4216 slidingly abuts against the inner surface of the pushing sleeve 431, thereby further reducing the wear. Can set up self-lubricating material layer on spacing boss 4216, reduce coefficient of friction, promote wearability, increase of service life.

In some embodiments, spaced protrusions may be further provided on the outer peripheral surface of the limit boss 4216 to further lower the contact surface.

In some embodiments, in order to achieve a stable pushing of the first transmission member 421, a support flange 4213 may be further provided on the first transmission member 421 for resting on an end surface of the push sleeve 431. A support flange 4213 may be disposed between the coupling end 4211 and the ejection end 4212. The transmission member 421 can be integrally formed, and it is not excluded that the transmission member is assembled after being separately molded.

In some embodiments, in order to ensure the structural strength, the first transmission member 421, the pushing sleeve 431, etc. often need a certain thickness; after assembly, the overall height tends to be high, and the required assembly space is correspondingly large. For this purpose, a counter-sunk seat 4313 can be provided on the end face of the thrust sleeve 431 for receiving the support flange 4213, reducing the overall height. To some extent, the rotation axis of the first transmission 421 can be maintained stable.

In some embodiments, in order to meet the requirement of the transmission connection between the first transmission member 421 and the upstream structure, it is necessary to provide a connection structure on the first transmission member 421. Therefore, the second transmission component 420 is further provided with a second transmission member 422, which is used for driving the first transmission member 421 and is connected with the upstream structure, so as to transmit the transmission torque.

In some embodiments, considering that the first transmission member 421 needs to move along the first direction and further needs to satisfy the torque transmission, the first transmission member 421 may be sleeved on the second transmission member 422 and may rotate along with the second transmission member 422 to achieve the torque transmission; at the same time, it is movable in a first direction relative to second transmission 422.

In some embodiments, in order to realize relative sliding and following rotation of the first transmission member 421 and the second transmission member 422, an axial through groove 4217 is formed on an inner surface 4214 of the first transmission member, and a latch 4222 which can be embedded in the axial through groove 4217 is formed on an outer surface 4221 of the second transmission member, so that the first transmission member 421 can rotate along with the second transmission member 422. Meanwhile, the latch 4222 can also slide along the axial through slot 4217, so that the first transmission piece 421 can slide in the first direction relative to the second transmission piece 422.

To meet torque transfer requirements, a drive shaft 423 may be coaxially secured within second transmission 422 for connection to upstream drive structure 110, driving second transmission 422.

In some embodiments, in order to fix the transmission shaft 423 in the second transmission member 422, a transmission shaft hole 4223 is formed in the second transmission member 422, a first limiting surface 4224 is disposed on the transmission shaft hole 4223, and a second limiting surface 4231 is disposed on an outer circumferential surface of the transmission shaft 423, wherein when the transmission shaft 423 is embedded in the transmission shaft hole 4223, the second limiting surface 4231 abuts against the first limiting surface 4224, so as to limit the rotation of the transmission shaft 423 relative to the second transmission member 422.

In some embodiments, to meet the requirement of manufacturability and simplify the forming process, the transmission shaft 423 may be configured as a cylindrical member, and a tangential plane may be configured on the outer circumferential surface of the cylindrical member to form the second stopper surface 4231. In cooperation, the transmission shaft hole 4223 is configured in a cooperating shape.

In some embodiments, the first transmission component 410 and the second transmission component 422 are coaxially sleeved on the transmission shaft 423, so that the second transmission component 420 can stably move towards or away from the first transmission component 410 along the axial direction of the transmission shaft 423, and the stability of connection and disconnection of the first transmission component 410 and the second transmission component 420 is ensured.

In some embodiments, the pushing sleeve 431 is movable in a first direction, and the pushing rod 432 is movable in the first direction.

In some embodiments, since the overall thickness space is small, the formation in the thickness direction is also relatively small, and the specification of the pushing structure is set to be small for direct pushing in the first direction, which undoubtedly greatly increases the difficulty in molding and assembling. Therefore, a structure for changing direction and pushing can be arranged; a first pushing surface 4311 in a non-parallel state with the first direction may be disposed on the pushing sleeve 431, so that a pushing operation along the pushing direction can be realized by pushing the first pushing surface 4311, and the pushing rod 432 pushes the first pushing surface 4311 to push the pushing sleeve 431 to the first transmission assembly 410.

In some embodiments, in order to optimize the pushing efficiency, the angle between the first pushing surface 4311 and the first direction may be set to be in a range of 30 degrees to 60 degrees, such as 30 degrees, 45 degrees, or 60 degrees.

In some embodiments, an included angle between the pushing direction of the push rod 432 and the first direction can be controlled according to 90 degrees, so as to minimize an arrangement space required by the matching arrangement of the push rod 432 and the second transmission assembly 420, and reduce the overall volume scale of the device.

In some embodiments, in order to improve the stability of the direction-changing pushing, a second pushing surface 4321 in contact with the first pushing surface 4311 may be disposed on the push rod 432, so as to improve the force uniformity of the first pushing surface 4311 by way of surface-to-surface contact pushing dislocation, thereby ensuring the stability of the moving posture of the pushing sleeve 431.

In some embodiments, in order to balance the force applied to the pushing sleeve 431, the number of the first pushing surfaces 4311 may be two, and the corresponding push rod 432 is also provided with two push arms 4323 for pushing the two first pushing surfaces 4311 correspondingly; thereby ensuring the force uniformity of the pushing sleeve 431 in a two-point force application mode. And two push arms 4323 can be connected to the same connecting portion 4324, so as to achieve synchronous action, ensure the magnitude of the applied force to be consistent, and ensure the uniform stress of the push sleeve 431. Correspondingly, the two pushing arms 4323 are respectively provided with a second pushing surface 4321.

In some embodiments, two first pushing surfaces 4311 may be disposed on opposite sides of the pushing sleeve 431, two pushing arms 4323 are disposed in parallel, and a second pushing surface 4321 is disposed on an end of the pushing arm 4323 away from the connecting portion 4324, so that the pushing operation can be achieved by pushing the connecting portion 4324.

In some embodiments, the number of the first pushing surface 4311, the second pushing surface 4321 and the pushing arm 4323 may be two or more according to the specification of the pushing sleeve 431.

In some embodiments, in order to limit the rotation of the pushing sleeve 431, a first pushing groove 4312 may be formed in the pushing sleeve 431, and the push rod 432 and the pushing sleeve 432 are connected into a whole by embedding the push rod 432 in the pushing groove 4312, so as to limit the circumferential relative rotation, and ensure the reliability of the pushing operation.

In some embodiments, the first pushing groove 4312 may be provided in two, the push rod 432 may be provided in two pushing arms 4323 arranged in parallel, and the two pushing arms 4323 are connected by a connecting portion 4324. The two first pushing grooves 4312 are arranged on two opposite sides of the pushing sleeve 431, so that two points are stably limited, and the stress stability of the pushing sleeve 431 is ensured. Correspondingly, the groove walls of the two first pushing grooves 4312 are respectively provided with a first pushing surface 4311.

In some embodiments, the two pushing arms 4323 may be provided with second pushing surfaces 4321 at ends thereof away from the connecting portion 4324, and the two second pushing surfaces 4321 are in contact with the two first pushing surfaces 4311.

In order to limit the radial offset of the push sleeve 431, limit baffles 4322 may be respectively disposed on the two push arms 4323, and specifically, the limit baffles 4322 are disposed on a side of the push arm 4323 away from the other push arm, so that the two limit baffles 4322 are blocked on two opposite sides of the push sleeve.

In order to perform the pushing operation of the push rod 432, a linear driver 433 may be connected to the push rod 432, and the push rod 432 is pushed in the second direction or reset, so that the push sleeve 431 is pushed by the linear driver 433 to move in the second direction, thereby realizing the connection between the first transmission assembly 410 and the second transmission assembly 420, and establishing a torque transmission structure of the clutch device. When the linear driver 433 is reset, the push rod 432 releases the pushing sleeve 431, so that the first transmission assembly 410 and the second transmission assembly 420 are disconnected, and the torque transmission structure of the clutch device is disconnected.

In some embodiments, the linear actuator 433 may employ a linear actuator assembly such as an electromagnetic push rod, a ball screw, or the like.

In some embodiments, the drive is provided as a reduction motor, or a motor equipped with a reduction gearbox, to enable reasonable control of output torque and rotational speed.

When clutch control is executed, the push rod 432 is pushed to move towards the push sleeve 431 through the action of the linear driver 433, the second push surface 4321 arranged at the head end of the push rod 432 pushes the first push surface 4311 to realize upward dislocation of the push sleeve 431, so that the push sleeve 431 moves towards the first transmission component 410, and meanwhile, the first transmission piece 421 of the second transmission component 420 is driven to move towards the first transmission component 410 until the connecting end 4211 of the first transmission piece 421 is embedded into the clamping groove 411 of the first transmission piece 410 to establish a circumferential transmission connection relation, at the moment, the linear driver 433 stays at the current position, and the push sleeve 431 is supported at the bottom through the push rod 432, so that a transmission connection state is maintained; the driver rotates to drive the second transmission member 422 to rotate, and then drives the first transmission member 421 and the first transmission assembly 410 to rotate, so as to implement power output. When the connection needs to be disconnected, the linear driver 433 resets, the pushing sleeve 431 naturally falls under the action of self weight, the connecting end 4211 is gradually separated from the clamping groove 411 until the connection between the first transmission piece 421 and the first transmission assembly 410 is disconnected, and the power output is interrupted. In the process, the first transmission member 421 can axially slide relative to the second transmission member 422, so that the vertical position is changed, and circumferential transmission is realized through the clamping and embedding action of the clamping block 4222 and the axial through groove 4217 in the first transmission member 421 and the second transmission member 422. It should be noted that the timing of the linear driver 433 does not necessarily precede the operation time of the driver, i.e., there is no necessary delay sequence between the two.
