The present embodiment provides a driving structure 20, wherein the driving structure 20 is used for a door lock, and includes a first transmission member 221, a first output member 231, and a second output member 232.

It should be noted that the terms "first", "second", and the like in the description and claims of the present application and in the above-described drawings are used for distinguishing different objects and not for describing a particular order.

The present embodiment provides a driving structure 20, which includes a first transmission element 221, a first output element 231, and a second output element 232. The three parts are mutually matched to enable the latch bolt, the lock tongue and the hook to slide so as to realize the locking and unlocking. The driving structure 20 according to the present embodiment can be applied to door locks of various fields and structures.

It should be noted that the rotation connection in the present application includes a direct rotation connection and an indirect rotation connection, and the sliding connection includes a direct sliding connection and an indirect sliding connection.

The driving structure 20 provided in this embodiment includes a first transmission member 221, and the first transmission member 221 can rotate to drive other components to rotate. In the present embodiment, the shape and size of the first transmission 221 are not limited. Alternatively, the first transmission 221 includes, but is not limited to, a gear having one circle of external teeth, a belt, or the like capable of rotating.

Optionally, the first transmission member 221 is connected to a motor. Therefore, the motor can control the first transmission piece 221 to rotate, so that the latch bolt, the lock tongue and the hook slide, thereby realizing automatic locking and unlocking. Alternatively, other components may be rotatably connected to the first transmission member 221, such as a knob, a lock cylinder 226, and the like, so that the first transmission member 221 is manually rotated to realize the locking and unlocking.

Alternatively, as shown in fig. 2, the first transmission piece 221 has a receiving space 221a, and the receiving space 221a is used for receiving the lock cylinder 226. Further alternatively, the first transmission piece 221 is a filter gear with external teeth, the filter gear has a receiving space 221a and a notch space communicated with each other, the lock cylinder 226 includes a lock cylinder 226 body and a protrusion, at least a part of the lock cylinder 226 body is disposed in the receiving space 221a of the filter gear, and at least a part of the protrusion is disposed in the notch space; when the lock cylinder 226 rotates, the protrusion portion can rotate toward a direction close to the first transmission member 221, so that the protrusion portion abuts against the first transmission member 221, and the lock cylinder 226 can drive the first transmission member 221 to rotate synchronously. Note that the filter finger is ring shaped with a notch.

In the embodiment, the accommodating space 221a for accommodating the lock cylinder 226 is additionally arranged in the first transmission piece 221, so that a way that a user can control the driving structure 20 from the outside through the lock cylinder 226 is increased, and because the first transmission piece 221 is a filter-shaped gear with external teeth, the lock cylinder 226, the first transmission piece 221 and other parts can be ensured to be in running fit, and the installation difficulty when the lock cylinder 226 is installed on the first transmission piece 221 is reduced and the installation efficiency is improved through a gap of the filter shape.

The driving structure 20 provided by the present embodiment further includes a first output element 231, and the first output element 231 can be connected to other components to drive the other components to rotate. The shape and size of the first output member 231 are not limited in this embodiment. In actual production, the first matching portion 2311 and the first output member 231 may be integrally formed structural members. The first mating portion 2311 is artificially named differently from the first output member 231 for ease of understanding. The shape of the first engagement portion 2311 is not limited in the present embodiment, and the first engagement portion 2311 may be engaged with the second engagement portion 2321. Optionally, the first output member 231 is a gear having one ring of external teeth. Specific structures of the first fitting portions 2311 will be described later.

The driving structure 20 provided by this embodiment further includes a second output element 232, and the second output element 232 can be connected to other components to drive the other components to rotate. In the present embodiment, the shape and size of the second output member 232 are not limited. In practical production, the second fitting portion 2321 and the second output member 232 may be integrally formed structural members. However, for ease of understanding, the second fitting 2321 is artificially named differently from the second output member 232. In the present embodiment, the shape of the second engagement portion 2321 is not limited, and it is only necessary to be able to engage with the first engagement portion 2311. Optionally, the second output 232 is a gear with one ring of external teeth. The specific structure of the second fitting portion 2321 will be described below.

Moreover, the rotation axis of the second output element 232 coincides with the rotation axis of the first output element 231, so that the first output element 231 can drive the second output element 232 to rotate to provide a basis when the subsequent first matching portion 2311 is matched with the second matching portion 2321. Optionally, the first output element 231 is sleeved on the second output element 232, or the second output element 232 is sleeved on the first output element 231, or both the first output element 231 and the second output element 232 penetrate through the first rotating shaft.

Specifically, when the first transmission member 221 rotates, the latch tongue can be driven to slide, and the first transmission member 221 can also drive the first output member 231 to rotate. Since the first output member 231 is provided with the first fitting portion 2311, the second output member 232 is provided with the second fitting portion 2321. First, when the first matching portion 2311 is separated from the second matching portion 2321, the first output element 231 and the second output element 232 can rotate independently, so when the first transmission element 221 drives the latch bolt to slide, the first transmission element 221 drives the first output element 231 to rotate, but the first output element 231 cannot drive the second output element 232 to rotate. In other words, the first transmission member 221 cannot drive the latch tongue connected to the second output member 232 and the ground hook. Secondly, when the first output element 231 rotates to the first matching portion 2311 and is abutted against the second matching portion 2321, the first output element 231 can drive the second output element 232 to rotate synchronously so as to control the movement of the lock tongue and the hook.

Therefore, in the present embodiment, the matching portion is disposed on the output member, so that the movement of the driving structure 20 for controlling the latch bolt is independent of the movement of the control latch bolt and the movement of the hook, thereby reducing the possibility of the mutual influence between the movement of the control latch bolt and the movement of the hook, and improving the working stability of the driving structure 20.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a driving structure according to another embodiment of the present disclosure. In one embodiment, the driving structure 20 further includes a third output member 233 and a limiting member 24, the third output member 233 is slidably connected to the first transmission member 221, and the limiting member 24 is configured to abut against or separate from a lock tongue or a hook connected to the second output member 232.

When the first transmission member 221 rotates, the third output member 233 is driven to rotate, so as to drive the limiting member 24 to slide along a direction away from the lock tongue and the top-bottom hook, so that the limiting member 24 is separated from the lock tongue and the top-bottom hook, and the lock tongue and the top-bottom hook can slide under the rotation of the second output member 232.

The driving structure 20 provided in this embodiment includes a third output member 233, and the third output member 233 can drive the limiting member 24 to slide. The present embodiment does not limit the shape and size of the third output device 233. Optionally, there are other components between the third output member 233 and the limiting member 24 to convert the rotation of the first transmission member 221 into sliding. Further optionally, the driving structure 20 further includes one of a rack and a dial, and the limiting member 24 is slidably connected to the rack or the dial. The third transmission member 223 can rotate to drive the rack to slide and/or the shifting piece to swing, so that the limiting member 24 slides.

The driving structure 20 provided by this embodiment further includes a limiting member 24, and the limiting member 24 is used for limiting a lock tongue and a top and bottom hook connected to the second output member 232. In the present embodiment, the shape and size of the stopper 24 are not limited. The position limiting member 24 has a position limiting state and an active state. When the limiting member 24 is in the limiting state, the limiting member 24 abuts against the lock tongue and the top and bottom hook connected with the second output member 232; when the position limiting member 24 is in the active state, the position limiting member 24 is separated from the lock tongue and the top and bottom hook connected to the second output member 232, and at this time, the lock tongue and the top and bottom hook can slide under the rotation of the second output member 232.

Specifically, when the position limiting element 24 is switched from the position limiting state to the active state, the first transmission element 221 rotates to drive the third output element 233 to rotate, so as to drive the position limiting element 24 to slide along the direction away from the lock tongue and the top-bottom hook, and further separate the position limiting element 24 from the lock tongue and the top-bottom hook. When the position limiting member 24 is switched from the active state to the position limiting state, the first transmission member 221 rotates in the opposite direction to drive the third output member 233 to rotate in the opposite direction, so as to drive the position limiting member 24 to slide in the direction close to the lock tongue and the top-bottom hook, and further to make the position limiting member 24 abut against the lock tongue and the top-bottom hook.

In the embodiment, by additionally arranging the limiting piece 24, when the lock tongue and the hook slide, the limiting piece 24 is in a movable state; when the lock tongue does not slide with the top and bottom hook, the position limiting member 24 is in the position limiting state, so that the probability that the lock tongue slides randomly with the top and bottom hook is reduced, and the reliability of the driving structure 20 is improved.

Optionally, as shown in fig. 5, the driving structure 20 further includes a second elastic member 245 and a first fixing member 246, one end of the second elastic member 245 is connected to the limiting member 24, and the other end is connected to the first fixing member 246; when the limiting piece 24 slides in a direction away from the lock tongue and the hook, the limiting piece 24 is separated from the lock tongue and the hook and the elastic piece is in a deformation state; the resilience of the second elastic member 245 enables the limiting member 24 to slide along the direction close to the lock tongue and the hook, and the limiting member 24 abuts against the lock tongue and the hook.

In this embodiment, the second elastic member 245 is additionally provided, so that the limiting member 24 can be switched from the active state to the limiting state under the action of the resilient force, thereby further reducing the probability that the lock tongue and the hook slide freely, and further improving the reliability of the driving structure 20. For example, when the motor stops moving, under the effect of the rebounding force, the limiting piece 24 is in a limiting state, and the bolt and the hook cannot slide, so that the locking and unlocking state of the door lock cannot be changed, the next locking and unlocking of the user is affected, and the difficulty of the locking and unlocking of the user is reduced.

Referring to fig. 6 to 7, fig. 6 is a schematic structural diagram of a first output device and a third output device according to an embodiment of the present disclosure. Fig. 7 is an exploded view of the first output element and the third output element according to an embodiment of the present disclosure. In one embodiment, the rotation axis of the third output member 233 coincides with the rotation axis of the first output member 231, the third output member 233 is provided with a third engagement portion 2331, and the first output member 231 is provided with a fourth engagement portion 2312.

When the position-limiting element 24 abuts against the lock tongue and the hook, and the third matching portion 2331 is separated from the fourth matching portion 2312, the first transmission element 221 can drive the third output element 233 to rotate relative to the first output element 231.

When the limiting member 24 is separated from the lock tongue and the top and bottom hook, and the third matching portion 2331 abuts against the fourth matching portion 2312, the third output member 233 can drive the first output member 231 to rotate synchronously, so as to drive the first output member 231 and the second output member 232 to rotate synchronously, so as to enable the lock tongue and the top and bottom hook to slide.

The third output member 233 provided in this embodiment is provided with a third engagement portion 2331, and the first output member 231 is provided with a fourth engagement portion 2312. In actual production, the third fitting portion 2331 and the third output member 233 may be integrally formed structural members. But the third fitting portion 2331 is artificially named differently from the third output member 233 for the convenience of understanding. The fourth mating portion 2312 and the first output member 231 may be integrally formed structural members. But the fourth mating part 2312 is artificially named differently from the first output member 231 for easy understanding. In the present embodiment, the shapes of the third and

fourth engagement portions

2331 and 2312 are not limited, and the third and

fourth engagement portions

2331 and 2312 may be engaged with each other. Specific structures of the third and fourth

fitting portions

2331 and 2312 will be described later.

Moreover, the rotation axis of the third output element 233 coincides with the rotation axis of the first output element 231, which provides a basis for the third output element 233 to drive the first output element 231 to rotate when the subsequent third matching portion 2331 matches with the fourth matching portion 2312. Optionally, the first output element 231 is sleeved on the third output element 233, or the third output element 233 is sleeved on the first output element 231, or both the first output element 231 and the third output element 233 penetrate through the second rotating shaft.

First, when the limiting member 24 is in the limiting state and the third matching portion 2331 is separated from the fourth matching portion 2312, the third output member 233 and the first output member 231 can rotate independently, so that when the first transmission member 221 rotates, the first transmission member 221 drives the third output member 233 to rotate, and further the limiting member 24 slides, but the third output member 233 cannot drive the first output member 231 to rotate. In other words, at this time, the first transmission member 221 cannot drive the latch tongue connected to the second output member 232 to slide along the hook. However, when the position-limiting element 24 is in the active state and the third matching portion 2331 abuts against the fourth matching portion 2312, the third output element 233 can drive the first output element 231 to rotate synchronously, so as to control the movement of the latch bolt and the hook.

Therefore, in the present embodiment, the engaging portions are disposed on the third output member 233 and the first output member 231, so that the movement of the driving structure 20 for controlling the limiting member 24 is independent of the movement of the control lock tongue and the movement of the hook, thereby reducing the possibility of the mutual influence between the movement for controlling the limiting member and the movement for controlling the lock tongue and the hook, and reducing the probability of the driving structure 20 being stuck, thereby improving the working stability of the driving structure 20.

In this embodiment, the first output element 231 and the third output element 233 are sleeved on the second output element 232, and the matching portion is disposed on the peripheral sidewall or one side surface of the output element, so that the occupied space of the first output element 231, the second output element 232 and the third output element 233 in the driving structure 20 is reduced, the integration level of the first output element 231, the second output element 232 and the third output element 233 is improved, more space can be left for other components in the driving structure 20, and the overall thickness of the driving structure 20 can be reduced.

Referring to fig. 2, fig. 8 and fig. 9 again, fig. 8 is a schematic structural view illustrating a fifth matching portion and a fourth output element of a driving structure according to an embodiment of the present disclosure being separated from each other. Fig. 9 is a schematic structural diagram of a fifth matching portion of a driving structure abutting against a fourth output member in an embodiment of the present application.

In one embodiment, the driving structure 20 further includes a fourth output member 234 slidably connected to the first transmission member 221, the fourth output member 234 is used for connecting the latch tongue, and the first transmission member 221 is provided with a fifth matching portion 2211.

When the fifth matching portion 2211 is separated from the fourth output element 234, the first transmission element 221 rotates to drive the first output element 231 to rotate, so as to drive the first output element 231 to drive the second output element 232 to rotate synchronously, so as to slide the latch bolt and the top and bottom hook; at the same time, the fifth matching part 2211 can be driven to rotate towards the direction close to the fourth output piece 234;

when the fifth matching portion 2211 abuts against the fourth output member 234, the first transmission member 221 can further drive the fourth output member 234 to slide, so as to slide the latch tongue.

The driving structure 20 of the present embodiment further includes a fourth output member 234, and the fourth output member 234 is capable of sliding relative to the housing to slide the latch. The shape and size of the fourth output member 234 are not limited in this embodiment. Further, the first transmission 221 of the present embodiment is provided with a fifth engagement portion 2211. In practical production, the fifth fitting portion 2211 and the first transmission member 221 may be integrally formed structural members. However, for the sake of easy understanding, the fifth fitting portion 2211 is named differently from the first transmission member 221. In the present embodiment, the shape of the fifth engagement portion 2211 is not limited, and it is sufficient that the fifth engagement portion 2211 can be engaged with the fourth output device 234. Optionally, the fifth mating portion 2211 is a protrusion.

First, when the fifth matching portion 2211 is separated from the fourth output element 234, the first transmission element 221 can rotate independently relative to the fourth output element 234, so when the first transmission element 221 rotates, the first transmission element 221 drives the first output element 231 and the second output element 232 to rotate, and further the latch bolt and the top-bottom hook slide, but the first transmission element 221 cannot drive the fourth output element 234 to slide. In other words, the first transmission member 221 cannot slide the latch tongue connected to the fourth output member 234. However, when the fifth matching portion 2211 contacts with the fourth output member 234, the first transmission member 221 can slide the fourth output member 234 to slide the latch tongue.

Therefore, in the present embodiment, the fifth engaging portion 2211 is disposed on the first transmission element 221, so that the movement of the driving mechanism 20 for controlling the latch bolt is independent of the movement of the control latch bolt and the movement of the hook, thereby further reducing the possibility of the mutual influence between the movement of the control latch bolt and the movement of the hook, further reducing the probability of the locking of the driving mechanism 20, and further improving the working stability of the driving mechanism 20.

Referring to fig. 10, fig. 10 is a schematic structural diagram of a driving structure according to another embodiment of the present application. In one embodiment, the driving structure 20 further includes a second transmission member 222 and a third transmission member 223. The second transmission piece 222 can rotate; and a third transmission member 223 rotatably connected to the first transmission member 221, the first output member 231, and the second transmission member 222.

When the second transmission member 222 rotates, the third transmission member 223 can be driven to rotate, so as to drive the first transmission member 221 to rotate, so that the latch bolt slides; when the third transmission member 223 rotates, the first output member 231 can be driven to rotate, so that the first output member 231 and the second output member 232 are driven to rotate synchronously, and the lock tongue and the top and bottom hook slide.

The driving structure 20 provided by the present embodiment further includes a second transmission member 222, and the second transmission member 222 can rotate to drive other components to rotate. In the present embodiment, the shape and size of the second transmission 222 are not limited.

And a fourth transmission member 224 rotatably connecting the first transmission member 221 and the second transmission member 222.

When the limiting member 24 abuts against the lock tongue and the hook, the second transmission member 222 can drive the fourth transmission member 224 to rotate, so as to drive the first transmission member 221 to rotate, so as to enable the latch bolt to slide.

The second transmission member 222 and the third transmission member 223 have been described above, and are not described herein again. The driving structure 20 of the present embodiment further includes a fourth transmission member 224, which can be connected to other components to drive the other components to rotate. In the present embodiment, the shape and size of the fourth transmission member 224 are not limited. Alternatively, fourth transmission member 224 includes, but is not limited to, a rotatable member such as a gear having a ring of external teeth, a belt, or the like.

Specifically, when the position limiting element 24 is in the position limiting state, since the position limiting element 24 abuts against the lock tongue and the top-bottom hook, the second output element 232 connecting the lock tongue and the top-bottom hook and the third transmission element 223 are relatively fixed. At this time, the second transmission member 222 can drive the first transmission member 221 to rotate through the fourth transmission member 224, so that the latch bolt slides to realize the locking and unlocking.

In the present embodiment, by additionally providing the second transmission member 222, the third transmission member 223 and the fourth transmission member 224, the driving structure 20 can control the movement of the latch tongue through the second transmission member 222, the fourth transmission member 224 and the first transmission member 221, so that the way for a user to control the latch tongue is increased, and the reliability of the driving structure 20 is improved.

Optionally, the second transmission member 222 has a first space 222a, the first transmission member 221 is disposed in the first space 222a, the third transmission member 223 and the fourth transmission member 224 are disposed in the first space 222a, the third transmission member 223 is rotatably connected between the second transmission member 222 and the first transmission member 221, and the fourth transmission member 224 is rotatably connected between the second transmission member 222 and the first transmission member 221.

In the present embodiment, the second transmission 222 may be regarded as a ring gear having one outer tooth and one inner tooth, the first transmission 221 may be regarded as a sun gear having one outer tooth, and the third transmission 223 and the fourth transmission 224 may be regarded as a planetary gear having one outer tooth. The arrangement can reduce the space occupied by the first transmission piece 221, the second transmission piece 222, the third transmission piece 223 and the fourth transmission piece 224 in the driving structure 20, and improve the space utilization rate.

Further optionally, the driving structure 20 further comprises at least one balance member 225, wherein the balance member 225 is rotatably connected to the second transmission member 222; the balance member 225 and the third transmission member 223 are disposed on two opposite sides of the first transmission member 221; and/or the balancing member 225 and the fourth transmission member 224 are disposed on opposite sides of the first transmission member 221. In the present embodiment, the balance member 225 is disposed to ensure that when the first transmission member 221, the second transmission member 222, the third transmission member 223, and the fourth transmission member 224 are mutually engaged, the probability of the second transmission member 222 being jammed due to imbalance is reduced, and the working stability of the driving structure 20 is improved.

Referring to fig. 10, and fig. 11-13 together, fig. 11 is an exploded view of a clutch assembly according to an embodiment of the present application. FIG. 12 is a schematic diagram of a clutch assembly in a synchronized state according to an embodiment of the present application. FIG. 13 is a schematic diagram of a clutch assembly in a free state according to an embodiment of the present application. Note that the motor is not shown in fig. 11 to 13.

In one embodiment, the driving structure 20 further comprises a motor and clutch assembly 40, and the clutch assembly 40 comprises a bracket 41, an oscillating member 42, and a clutch member 43. The holder 41 has an accommodating space 41a. The swinging member 42 is connected to the motor and rotatably connected to the bracket 41. And at least part of the clutch 43 is arranged in the accommodating space 41a, and the clutch 43 is rotatably connected with the second transmission piece 222.

Wherein when the motor drives the oscillating member 42 to rotate to a non-synchronized position with respect to the holder 41, the oscillating member 42 is disengaged from the clutch member 43 to enable the oscillating member 42 to rotate with respect to the clutch member 43; when the motor drives the swinging member 42 to rotate relative to the bracket 41 to a synchronous position, the swinging member 42 abuts against the clutch member 43, so that the motor can drive the swinging member 42, the bracket 41, the clutch member 43 and the second transmission member 222 to rotate synchronously.

The driving structure 20 of the present embodiment includes a motor and a clutch assembly 40, the motor is used for driving the clutch assembly 40 to move, the clutch assembly 40 has a synchronous state that the oscillating member 42 and the clutch member 43 synchronously rotate, and the clutch assembly 40 also has a free state that the oscillating member 42 and the clutch member 43 respectively and independently move. When the clutch assembly 40 is in a synchronous state, the motor can drive the bracket 41, the oscillating member 42, the clutch member 43, and the second transmission member 222 to move synchronously because the oscillating member 42 abuts against the clutch member 43. In other words, at this time, the motor drives the clutch assembly 40 to move, so as to drive the second transmission member 222 to rotate, so as to control the latch bolt, and the top and bottom hook to slide, thereby implementing the switch lock. When the clutch assembly 40 is in the free state, the oscillating member 42 is separated from the clutch member 43, and the oscillating member 42 and the clutch member 43 rotate independently, so that the motor cannot drive the second transmission member 222 to rotate at this time. However, in this case, the driving structure 20 can drive the latch bolt, and the hook to slide through the first transmission member 221, thereby implementing the locking and unlocking.

Alternatively, with a forward rotating motor, the oscillating member 42 can be rotated to a non-synchronized position to free the clutch assembly 40. The oscillating member 42 can also be rotated to the synchronized position by reversing the motor to transition the clutch assembly 40 from the disengaged state to the synchronized state.

The clutch assembly 40 in the present embodiment is composed of a holder 41, an oscillating member 42, and a clutch member 43. The bracket 41 is used for connecting with other components or supporting and fixing other components. The oscillating member 42 can be coupled to other components or rotated relative to the other components to effect mating of the various components. Clutch member 43 is adapted to be coupled to another component and capable of rotating relative to oscillating member 42 or rotating synchronously with oscillating member 42 to effect clutching of clutch assembly 40. The clutching of the clutch assembly 40 means that the motor is disconnected from the second transmission 222 through the clutch assembly 40, or the second transmission 222 is driven to rotate through the motor, and the two states respectively correspond to the free state of the clutch assembly 40 and the synchronous state of the clutch assembly 40.

In the embodiment, the clutch assembly 40 is arranged, so that the clutch assembly 40 is in a synchronous state when the motor is required to drive the latch bolt, the lock bolt and the hook to slide; when the motor is not required to drive the latch bolt, the lock bolt and the ground hook to slide, the clutch assembly 40 is in a clutch state, the motor controls the movement of the latch bolt, the lock bolt and the ground hook through the second transmission piece 222 and controls the movement of the latch bolt, the lock bolt and the ground hook through the first transmission piece 221 to be independent respectively, the probability of jamming of the driving structure 20 is reduced, and therefore the working stability of the driving structure 20 is improved.

Referring again to fig. 11-13, in one embodiment, the clutch assembly 40 further includes a first elastic member 44, and the first elastic member 44 connects the swinging member 42 and the bracket 41.

When the motor drives the swinging member 42 to rotate relative to the bracket 41 to the synchronous position, the swinging member 42 abuts against the clutch member 43 and the first elastic member 44 is in a deformed state; the repulsive force of the first elastic member 44 enables the swinging member 42 to rotate to the non-synchronized position with respect to the bracket 41, and the swinging member 42 is separated from the clutch member 43.

The embodiment further includes a first elastic member 44, and the first elastic member 44 is used for connecting other components, so that the components connected with the first elastic member can be restored to the original position after being rotated or moved. Specifically, when the motor stops moving, the swinging member 42 can be rotated to the asynchronous position due to the rebounding force of the first elastic member 44, so that the clutch assembly 40 is in the free state, and the separation of the movement of the motor for controlling the latch bolt, the locking bolt and the ground hook through the second transmission member 222 and the movement of the latch bolt, the locking bolt and the ground hook through the first transmission member 221 can be further ensured, so that the probability of the jamming of the driving structure 20 is further reduced, and the working stability of the driving structure 20 is further improved.

The third rotating member 45 in this embodiment is capable of cooperating with the oscillating member 42 to control the state of the clutch pack 40. In the present embodiment, the shape and size of the third rotor 45 are not limited. Alternatively, the third rotating member 45 includes, but is not limited to, a gear having one outer tooth, a belt, or the like capable of rotating. For ease of understanding, the three rotating members will also be referred to hereinafter as toothed discs. In the present embodiment, the shapes of the fourth contact portion 451 and the fifth contact portion 421 are not limited. Optionally, the fourth abutting portion 451 and the fifth abutting portion 421 are protrusions. In the present embodiment, the motor can control the clutch assembly 40 to be in the synchronized state or the clutch state by driving the third rotating member 45 to rotate to control the fourth contact portion 451 to rotate toward or away from the fifth contact portion 421.
