[0078] Working principle of the small driving device for the track-type curtain

[0079] Overall structure and function

[0080] The small driving device for the track-type curtain is mainly composed of components such as a motor 30, a reducer 40, a motor output turntable 50, a transmission box 60, and a motor control circuit board 90. The device generates power through the motor, reduces the speed and increases the output torque through the reducer, and finally drives the transmission system to realize the automatic opening and closing of the curtain.

[0081] The working process is as follows:

[0082] Starting process: The user sends a start signal through the motor control circuit board 90, and the motor 30 starts to operate under the command of the control circuit board. The motor control circuit board is connected in the motor housing 10 through plug-in connection. After receiving the user input or automatic program control signal, it outputs an electrical signal to the motor to start the operation of the motor.

[0083] Power output: After the motor 30 operates, its output shaft transmits the rotational power to the reducer 40. The input shaft barrel 43 of the reducer is connected to the motor output shaft and transmits the high-speed rotational power to the first-stage sun gear 44 inside the reducer. The reducer 40 realizes the reduction of speed and the increase of torque through the internal planetary gear set (the first-stage planetary gear set 45 and the second-stage planetary gear set 48), and finally transmits the reduced power to the second-stage output turntable 49. The reducer output shaft barrel on the second-stage output turntable 49 is connected to the motor output turntable 50 to further transmit the power to the transmission system.

[0084] Operation of the transmission system: The motor output turntable 50 transmits the rotational power to the track system of the curtain through the transmission gear 70. The transmission shaft 71 of the transmission gear 70 is inserted into the shaft disc of the motor output turntable and rotates synchronously with the motor output turntable. The transmission box 60 is connected to the curtain track through the track plug interface 61, converts the rotational motion of the transmission gear into the linear motion of the curtain, and realizes the opening and closing of the curtain. The U-shaped transmission cavity 621 and the U-shaped stud cavity 622 provide the functions of support and guidance to ensure the stable operation of the transmission gear.

[0085] Control and Adjustment: The motor control circuit board 90 can adjust the operating state of the motor in real time through sensor feedback to ensure the smooth operation of the curtain on the track. The motor control circuit board can automatically adjust the opening and closing speed and position of the curtain according to the set program, and can also accept manual instructions for opening and closing adjustment. The system supports automatically opening and closing the curtain at a preset time to achieve intelligent control.

[0086] Protection and Maintenance: The bottom cover 410 and the top cover 411 of the gear barrel provide sealing protection for the reducer to prevent dust and foreign objects from entering. The motor housing 10 and the housing cover plate 20 are connected by bolts and buckles, which facilitates the disassembly and maintenance of the device. A modular design is adopted between the components, which is convenient for replacement and repair.

[0087] In specific implementation, the following additional functions can be realized in combination with the existing technology:

[0088] Intelligent Control: It can cooperate with the smart home system to achieve remote control through a mobile phone or a voice assistant.

[0089] Safety Protection: It has overload protection and power failure self-locking functions to ensure the safe operation of the system.

[0090] Energy-saving Design: The motor control circuit board is equipped with an energy-saving mode to reduce standby power consumption during non-use periods.
