In addition, the manual control part 4 can be adjusted by people to output power to the transmission assembly 2, and then the power is transmitted to the output part 5 through the transmission assembly 2 so as to control the retraction or the deployment of the blind. Therefore, the blind can be controlled in a manual control mode, and can be controlled in an electric control mode, so that the applicability of the blind control mechanism is effectively improved, and the blind can be controlled conveniently by people.

The relief groove 13 is formed in the upper shell 11 and the lower shell 12, and the relief groove 13 is communicated with the accommodating cavity. The cover plate 14 is disposed on a side of the upper housing 11 away from the lower housing 12, and the cover plate 14 is disposed above the self-control portion 3 to protect the self-control portion 3.

Referring to fig. 2 and 3, the transmission assembly 2 includes an output rod 21, a worm 22, and a worm wheel 23, the output rod 21 being rotatably disposed in the lower housing 12, one end of the worm 22 being connected to the output rod 21. The worm wheel 23 is rotatably disposed between the upper housing 11 and the lower housing 12, and the worm wheel 23 is engaged with the worm 22. When the output lever 21 rotates, the worm wheel 23 rotates in synchronization with the rotation of the output lever 21, and the worm wheel 23 rotates in synchronization due to the meshing connection of the worm wheel 23 and the worm 22. It should be noted that, the worm wheel 23 and the worm 22 are mutually matched, and have self-locking property, so that reverse self-locking can be realized, that is, only the worm 22 drives the worm wheel 23, but not the worm wheel 23 drives the worm 22.

The automatic control part 3 comprises a driving piece 31, a speed changer 32, an output shaft 33, a driving gear 34 and a driven gear 35, wherein the driving piece 31 is arranged on one side, deviating from the lower shell 12, of the upper shell 11, the speed changer 32 is fixedly connected to the driving end of the driving piece 31, and the speed changer 32 is arranged to regulate the output power of the motor. One end of the output shaft 33 is connected to the transmission 32, the driving gear 34 is sleeved outside the output shaft 33, the driven gear 35 is sleeved outside one end of the output rod 21 far away from the worm 22, and the driving gear 34 is meshed with the driven gear 35. When the driving member 31 is operated, the power of the driving member 31 is transmitted to the output shaft 33 through the transmission 32, so that the output shaft 33 rotates to drive the driving gear 34 to rotate. Since the driving gear 34 is engaged with the driven gear 35, the driven gear 35 rotates synchronously to rotate the output lever 21, and the worm wheel 23 rotates synchronously with the rotation of the output lever 21, the worm wheel 23 rotates synchronously due to the engaged connection of the worm wheel 23 and the worm 22. In this embodiment, the driving member 31 is a motor, the output shaft 33 of the motor is connected to the input shaft of the transmission 32, and in other embodiments, the driving member 31 may be another driving member 31 capable of driving the output shaft 33 to rotate through the transmission 32.

The self-control portion 3 further includes a fixing seat 36 and a limiting block 37, the fixing seat 36 is disposed on one side of the upper housing 11 away from the lower housing 12, and one end of the output shaft 33 away from the transmission 32 is rotatably disposed on the top end of the fixing seat 36, so as to support the output shaft 33, so that the output shaft 33 can stably rotate. The limiting block 37 is sleeved at one end of the output shaft 33 far away from the speed changer 32, and the limiting block 37 is arranged between the driving gear 34 and the fixed seat 36 so as to effectively reduce the axial sliding condition of the motor.

The hand control part 4 comprises a hand control rod 41 and a supporting seat 42, one end of the hand control rod 41 penetrates into the lower shell 12, and one end of the hand control rod 41 penetrating into the lower shell 12 is connected with one end of the output rod 21 far away from the worm 22.

By manually rotating the manual lever 41, the output lever 21 is rotated in synchronization, the worm wheel 23 is rotated in synchronization with the rotation of the output lever 21, and the worm wheel 23 is rotated in synchronization due to the meshing connection of the worm wheel 23 and the worm 22.

The output part 5 includes an output hole 51, the output hole 51 is formed in the center of the worm wheel 23, the output hole 51 penetrates the worm wheel 23, and when the upper housing 11 and the lower housing 12 are connected to each other, the output hole 51 and the relief groove 13 are on the same axis. By inserting the control shaft of the blind into the output hole 51 from the escape groove 13 provided in the upper case 11 or the lower case 12, the retraction and deployment operations of the blind can be controlled by the automatic control unit 3 or the manual control unit 4.

In summary, in the manual/automatic dimming mechanism of the present utility model, when the blind needs to be adjusted, the driving member 31 and the transmission 32 transmit power to the output shaft 33, so that the output shaft 33 rotates to drive the driving gear 34 to rotate. Since the driving gear 34 is engaged with the driven gear 35, the driven gear 35 rotates synchronously to rotate the output rod 21, and the worm wheel 23 rotates synchronously with the rotation of the output rod 21, and since the worm wheel 23 is engaged with the worm 22, the worm wheel 23 rotates synchronously, and thus the retraction and deployment actions of the blind are controlled through the output hole 51 on the worm wheel 23. If power failure or failure occurs, the manual control lever 41 is manually rotated to synchronously rotate the output lever 21, and the retraction and deployment actions of the blind are controlled through the cooperation of the worm wheel 23 and the worm 22. Therefore, the blind can be controlled in a manual control mode, and can be controlled in an electric control mode, so that the applicability of the blind control mechanism is effectively improved, and the blind can be controlled conveniently by people.
