Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The core of the invention is to provide a clutch which can simplify the structure of an intelligent curtain driving system and reduce the cost. The other core of the invention is to provide an intelligent curtain driving system comprising the clutch, which has a simple structure and can reduce the cost.

Referring to fig. 1 to 11, a first embodiment of a clutch provided by the present invention includes a clutch cover 2 and a clutch sleeve 3 axially fixed to one end of the clutch cover 2.

The clutch cover 2 is rotatably connected with a clutch piece 43, and the clutch piece 43 is axially movable. The clutch cover 2 is provided with a first axial through hole 21 to connect the clutch block 43 with an external device.

A drive block 5 is rotatably connected to the clutch sleeve 3. The clutch sleeve 3 is provided with a second axial through hole 31 to connect the driving block 5 with an external device. As shown in fig. 4, the driving block 5 is rotatably coupled to the second axial through hole 31 by a second bearing 53, and the second bearing 53 is axially positioned on the driving block 5 by a second snap ring 52.

Between the clutch block 43 and the drive block 5, the spring 1 and the electromagnetic assembly are arranged. Specifically, the elastic member 1 is a compression spring, and two ends of the elastic member respectively abut against the pressing surfaces corresponding to the clutch block 43 and the driving block 5, and may also be a spring plate or other elastic structures in other embodiments. Specifically, when the electromagnetic assembly is powered on, the provided magnetic force is opposite to the elastic force direction of the elastic member 1 and is greater than the elastic force of the elastic member 1, so that the deformation degree of the elastic member 1 can be increased.

As shown in fig. 5, 10 and 11, when the electromagnetic assembly is de-energized, the clutch block 43 and the driving block 5 are kept separated by the elastic force of the elastic member 1, so that the clutch block 43 and the driving block 5 move independently.

When the electromagnetic assembly shown in fig. 4, 8 and 9 is energized, the electromagnetic assembly provides a magnetic force to overcome the elastic force of the elastic member 1, so that the clutch block 43 is axially approached and connected to the driving block 5, so that the driving block 5 can rotate synchronously with the clutch block 43.

The clutch in this embodiment is applied to an intelligent curtain driving system, the clutch block 43 is connected to the driving motor 10 in a transmission manner, and the driving block 5 is connected to the curtain body in a transmission manner. In the using process, if the electromagnetic assembly is powered on, as shown in fig. 4, the clutch block 43 can be driven by the magnetic force provided by the electromagnetic assembly to overcome the elastic resetting force of the elastic member 1 until the clutch block 43 is connected with the driving block 5, at this time, if the driving motor 10 drives the clutch block 43 to rotate, the driving block 5 can synchronously rotate along with the clutch block 43, and then the curtain body is driven to be pulled open or closed; on the contrary, as shown in fig. 5, if the electromagnetic assembly is powered off and the magnetism disappears, the clutch block 43 is far away from the driving block 5 under the action of the reset elasticity of the elastic member 1, so that the clutch block 43 is disconnected from the driving block 5, the clutch block 43 is separated from the driving block 5, the clutch block 43 can not drive the driving block 5 to rotate any more, and at this time, no matter whether the driving motor 10 continues to operate, the corresponding curtain body can not be driven by the driving block 5. Of course, in other embodiments, the driving block 5 may be connected to the driving motor in a transmission manner, and the clutch block 43 may be connected to the curtain body.

The clutch in the embodiment can enable the clutch block 43 to axially move under the action of the electromagnetic assembly and the elastic part 1 only by controlling the on-off of the electromagnetic assembly, so that the clutch block 43 and the driving block 5 are connected and separated, load equipment connected with the clutch can be driven by the driving motor 10 or not controlled by the driving motor, the structure is simple, the control is convenient, the structure of a driving system is simplified, and the cost is reduced.

Furthermore, an inserting structure is arranged between the clutch block 43 and the driving block 5, so that when the electromagnetic assembly is electrified, the clutch block 43 and the driving block 5 are inserted and matched through the inserting structure to rotate synchronously. In the embodiment, the rotation freedom degree between the clutch block 43 and the driving block 5 is limited through the insertion and matching, so that the clutch block and the driving block keep synchronous rotation, the structure is simple, and the processing is convenient.

Further, as shown in fig. 6 and 7, the insertion structure includes a bevel gear structure provided on the axial end surfaces of both the clutch block 43 and the drive block 5 that are close to each other. More specifically, the bevel gear structure comprises a bevel gear meshing female end 41 arranged on the clutch block 43 and a bevel gear meshing male end 51 arranged on the driving block 5, and after the two are axially plugged, through meshing fit, circumferential limiting and synchronous rotation between the clutch block 43 and the driving block 5 can be realized. Adopt the conical gear structure as grafting structure, can improve transmission effect, simultaneously, because conical gear has the inclined plane, has the guide effect, can guarantee that conical gear meshing male end 51 and conical gear meshing female end 41 can automatic circumference adjustment position relation in order to mesh in the axial motion in-process.

Of course, in other embodiments, the insertion structure may also include a plug disposed on the clutch block 43 and a socket disposed on the driving block 5, and the circumferential limitation of the clutch block 43 and the driving block 5 is realized by the insertion of the plug and the socket. In addition, the clutch block 43 and the driving block 5 may be connected to limit the circumferential direction by using a frictional force between the two instead of the insertion structure.

Further, as shown in fig. 4 and 5, the clutch further includes a rotating block 42 rotatably connected to the first axial through hole 21, and the position of the rotating block 42 in the axial direction is not changed. Specifically, the rotating block 42 may be coupled to a first bearing 45 via a first snap ring 44 and rotatably coupled to the first axial through hole 21 via the first bearing 45. The turning block 42 and the clutch block 43 are arranged in this order in the axial direction and in the direction of approach to the drive block 5.

The clutch block 43 and the rotating block 42 constitute an input structure 4, and the clutch block 43 is connected to an external device such as the drive motor 10 through the rotating block 42. Specifically, as shown in fig. 2 and 4, a partial structure of the turning block 42 axially protrudes through the first axial through hole 21 to connect external equipment through the input structure fastening bolt 46.

Wherein, the rotating block 42 is connected with the clutch block 43 through the rotation limiting structure and rotates synchronously, and the clutch block 43 can move axially relative to the rotating block 42, wherein, the axial movement of the clutch block 43 relative to the rotating block 42 is realized through the driving of the elastic piece 1 and the electromagnetic assembly. Specifically, as shown in fig. 5 to 7, the rotation limiting structure includes a square column fixed on the rotating block 42 and a square hole opened on the clutch block 43, the square column and the square hole are in insertion fit along the axial direction, and the square column can guide the axial movement of the clutch block 43 and simultaneously limit the clutch block 43 to rotate synchronously with the rotating block 42.

In this embodiment, since the axial position of the rotating block 42 is not changed, it is convenient for connecting the rotating block with an external device. When the rotating block 42 rotates, the clutch block 43 can be driven to rotate synchronously no matter how the axial position relation between the clutch block 43 and the rotating block 42 is. Specifically, when the clutch block 43 moves axially to be connected with the driving block 5, the rotating block 42 can drive the clutch block 43 and the driving block 5 to rotate synchronously; when the clutch block 43 moves axially to be separated from the driving block 5, the rotating block 42 drives the clutch block 43 to rotate but does not drive the driving block 5. Of course, in other embodiments, the turning block 42 may not be provided, but may be directly in transmission connection with the driving motor 10 via the clutch block 43.

Further, as shown in fig. 4, the electromagnetic assembly includes an electromagnet 6 and a flapper 7 that can be magnetically attracted. Optionally, the movable baffle 7 is made of a metal member such as an iron plate that can be magnetically attracted, or the movable baffle 7 is a magnet. The electromagnet 6 is arranged in the clutch sleeve 3, and the movable baffle 7 is connected with the clutch block 43 and can synchronously move axially. Wherein, the attraction force of the electromagnet 6 to the movable baffle 7 must be larger than the elastic force of the elastic piece 1.

In this embodiment, the movable baffle 7 is connected to the clutch block 43 and drives the clutch block 43 to move axially, and compared with the embodiment in which the electromagnet 6 is connected to the clutch block 43, the structure such as a line connected with the electromagnet 6 does not need to move axially, which is beneficial to simplifying the equipment.

Further, as shown in fig. 3 and 4, the electromagnet 6 is a ring-shaped electromagnet sleeved on the driving block 5. Because the electromagnet 6 is of a circular ring structure, the electromagnet 6 can be matched with the second axial through hole 31 to support the driving block 5, and the stability of the driving block 5 is improved. Of course, in other embodiments, the electromagnet 6 may be a bar or other shape.

Further, as shown in fig. 4, the electromagnet 6 is fixedly connected to the clutch sleeve 3, and the movable baffle 7 is rotatably sleeved outside the clutch block 43.

The electromagnet 6 is provided with a guide post 61, the movable baffle 7 is provided with a guide hole 71 which is sleeved with the guide post 61, so that the movable baffle 7 and the electromagnet 6 move synchronously in the circumferential direction through the sleeve connection of the guide post 61 and the guide hole 71, and correspondingly, the movable baffle 7 can keep static in the circumferential direction along with the electromagnet 6 and cannot rotate along with the clutch block 43 because the electromagnet 6 keeps static in the circumferential direction. In addition, the flapper 7 is capable of moving axially under the guidance of the guide post 61. Of course, in other embodiments, the guide post 61 may be provided on the flapper 7 and the guide hole 71 may be provided on the electromagnet 6.

In this embodiment, since the electromagnet 6 is fixedly connected to the clutch sleeve 3, the circuit of the electromagnet 6 can also be kept stationary, which is convenient for the electrical connection of the circuit of the electromagnet 6 and the stable transmission of signals. In addition, due to the sleeving connection of the guide post 61 and the guide hole 71, the stability of the axial movement of the movable baffle 7 can be ensured. In addition, the movable baffle 7 is limited by the electromagnet 6 in the circumferential direction and cannot rotate along with the clutch block 43, so that the number of parts needing to rotate in the clutch can be reduced, and the shaking condition in the running process is reduced.

Further, as shown in fig. 4 and 7, the clutch block 43 includes a stepped shaft structure, and specifically, a tapered gear engagement female end 41 and the stepped shaft structure are provided on the clutch block 43 in this order in a direction axially away from the drive block 5. In the axial direction, the large-diameter section 433 and the small-diameter section 432 of the stepped shaft structure are arranged in sequence in a direction away from the driving block 5. The small diameter section 432 is sleeved with the movable baffle 7, and the movable baffle 7 is specifically a circular ring plate. The movable baffle 7 abuts against a shaft shoulder 431 between the small-diameter section 432 and the large-diameter section 433 to limit the limit position of the movable baffle 7 close to the electromagnet 6 along the axial direction.

In this embodiment, the movable baffle 7 is connected to the stepped shaft structure of the clutch block 43, so that the assembly is facilitated, and the reliable axial movement of the movable baffle 7 and the clutch block 43 can be ensured. Specifically, when the electromagnet 6 is powered on, the movable baffle 7 is attracted by the electromagnet 6, and presses the shaft shoulder 431 of the stepped shaft structure to drive the clutch block 43 to move towards the driving block 5; when the electromagnet 6 is powered off, the clutch block 43 is driven by the elasticity of the elastic piece 1 to be far away from the driving block 5, and the shaft shoulder 431 of the stepped shaft pushes the movable baffle 7 to move synchronously along the axial direction.
