The structure is ingenious and easy to use.

[0031] As a preference, Figure 2 As shown, the clutch module 2 includes a clutch part 21 , and the output module 3 includes a transmission part 31 . The clutch part 21 moves along the axial direction to engage with or disengage from the transmission part 31 .

[0033] Thus, the drive shaft 11 is pulled toward the end away from the transmission part 31 , and due to the limiting of the snap ring 23 , the clutch part 21 moves synchronously with the drive shaft 11 .

[0034] Preferably, the transmission part 31 is coaxially sleeved on the driving shaft 11 to ensure coaxiality.

[0035] As a preference, Figure 1 As shown, the driving unit 1 also includes a base 12, the driving shaft 11 is installed on the base 12 and its two shaft ends pass through the base 12, its front end output end is connected to the clutch module 2, and its rear end input end is connected to the control module 4.

[0036] As a preference, Figure 3 As shown, the control module 4 includes: a steel wire rope 41, which is connected to the drive shaft 11 and is used to pull the drive shaft 11; and an elastic member 42, which is used to push the drive shaft 11 to reset.

[0037] Preferably, the control module 4 also includes: a mounting seat 43, which is installed at the rear end of the driving part 1, and one end of the driving shaft 11 and the wire rope 41 extends into the mounting seat 43 for docking; and a connecting seat 44 arranged in the mounting seat 43, and the connecting seat 44 is connected between the driving shaft 11 and the wire rope 41; an elastic member 42 is installed between the connecting seat 44 and the mounting seat 43.

[0042] Embodiment 2

[0043] The components of this embodiment that are the same as or corresponding to those in the above embodiment are marked with the same reference numerals as those in the above embodiment. For the sake of simplicity, only the differences from the above embodiment are described below. The differences between this embodiment and the above embodiment are:

[0044] As a preference, Figure 2 , 5 As shown, a clamping block 211 is axially protruded on the end surface of the clutch part 21 facing the transmission part 31 , and a clamping groove 311 is axially recessed on the end surface of the transmission part 31 facing the clutch part 21 , and the clamping block 211 is matched and clamped in the clamping groove 311 .

[0046] Therefore, when the transmission connection action is restored, if the clamping block 211 is misaligned with the clamping slot 311 , the transmission part 31 only needs to slightly rotate to make the clamping block 211 fall into the clamping slot 311 again.

[0047] When the rolling door needs to be electrically controlled to be raised or lowered, the driving unit 1 drives the output module 3 to rotate; when the rolling door needs to be manually pushed or pulled, the wire rope 41 is pulled to disengage the clutch unit 21 from the transmission unit 31, that is, the driving unit 1 and the output module 3 are disconnected from the transmission connection, and the rolling door can now be easily pushed or pulled manually.

[0048] When it is necessary to restore the transmission connection between the drive unit 1 and the output module 3, the wire rope 41 is loosened, and the drive shaft 11 and the clutch unit 21 are axially moved and reset under the elastic force of the elastic member 42, so that the clutch unit 21 and the transmission unit 31 are restored to engage with each other. It should be noted that even if the block 211 and the slot 311 are misaligned at this time, the block 211 can fall back into the slot 311 when the transmission unit 31 rotates slightly, thereby realizing rapid restoration of the transmission connection.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
