A motor drive system for operating a mechanism for raising and lowering window coverings includes a motor operating under electrical power and an electrically powered drive system. The motor drive system advances a continuous cord loop in response to positional commands from a controller. An input-output device includes a capacitive touch strip that receives user inputs along an input axis, and an LEDs strip aligned with the input axis. A group mode module communicates the positional commands to other motor drive systems within an identified group to operate respective other mechanisms of the other motor drive systems. A set control module enables user calibration of a top position and a bottom position of travel of the window covering. The input-output device extends vertically on the exterior of a housing for the motor drive system, and the housing supports input buttons of the group mode module and the set control module.

The present disclosure relates to a method and a device for adjusting indoor illumination intensity. In the method, a target illumination intensity value is acquired when a target electric appliance is running and the target electric appliance is susceptible to illumination intensity in a room. In the method, a first indoor illumination intensity value in the room is collected, and an indoor illumination intensity adjustment device is controlled according to the first indoor illumination intensity value and the target illumination intensity value. The indoor illumination intensity adjustment device is controlled to change the first indoor illumination intensity value to achieve a second indoor illumination intensity value where the second indoor illumination intensity value conforms to the target illumination intensity value.

An electric curtain assembled with an accessory (900) includes a curtain rod (1), a frame (2, 3), and a coupling member (4A, 4B, 4C). The frame (2, 3) is detachably installed and movably fixed to an end of the curtain rod (1), and the fixed frame (2, 3) has a protruding structure (T1 or T2) protruding from an end of the curtain rod (1), and the protruding structure (T1 or T2) includes a fixed portion (25 or 35) with a driven wheel (23 or 24), and the coupling member (4A, 4B, 4C) is detachably connected between the protruding structure (T1 or T2) and the connected accessory (900) is disposed between the curtain rod (1) and the accessory (900). The electric fan has the effects of installing or moving the accessory (900) and the coupling member (4A, 4B, 4C), and adjusting the tightness of the belt effectively.

A non-return mechanism for a motor of an electric curtain is provided which comprises a motor and a gearbox that are successively connected; the output end of the gearbox is connected with a non-return component; the non-return component comprises a flange, an output shaft and a non-return block, the output end of the gearbox is provided with an output bracket; the output bracket is in unidirectional drive fit with one end of the output shaft toward the gearbox and they fit within the accommodating cavity; the output shaft and the non-return block, together with the unidirectional drive fit with the output bracket, a non-return force is effectively generated to steadily maintain the curtain at the required position when the motor stops without damaging the gearbox and the motor as the output shaft reversely drives the gearbox and the motor under the effect of an external force or gravity.

Disclosed are an electric spiraling piston and systems, devices, apparatuses, and methods utilizing same. An electric spiraling piston includes a drum around which the piston spirals as it is being retracted. A spinning axis of the drum is functionally connected to the drive shaft of a motor, such that motor torque is relayed to the axis. The axis, when spinning with the drum in a first direction, causes the piston to un-spiral and extend out of a housing —while rounding its cross section — to assume a straight, rigid position/orientation. The Axis, when spinning with the drum in a second direction, causes the piston to be retracted back into the housing — while flattening its cross section — to assume a spiral orientation within the housing.

A motor driven system for raising and lowering a window covering executes motor ramp trajectory speed control. The motor ramp trajectory limits acceleration of an external motor from the idle (stationary) state to full operating speed, and limits deceleration of the motor from full operating speed back to the idle state. This function reduces stresses on a continuous cord loop drive mechanism. A control system manages solar heating effects in response to sunlight entrance conditions such as system sensor outputs, external weather forecasts, and other data sources. The system automatically opens or close the window covering to increase or decrease admitted sunlight under appropriate conditions. The input interface of the control system includes a visual display and input axis, which are aligned vertically if the window covering mechanism raises and lowers the window covering, and are aligned horizontally if the window covering mechanism laterally opens and closes the window covering.

A telescopic electric curtain guiderail is provided which comprises a first guiderail piece in which a hollow telescopic receiving cavity is disposed and at a first side of which a first curtain guiderail is disposed; a second guiderail piece, sleeved into the telescopic receiving cavity to perform reciprocating movement along a length direction of the first guiderail piece in the telescopic receiving cavity, where a second curtain guiderail capable of combining with the first curtain guiderail is disposed on the second guiderail piece; and an adjusting mechanism, capable of controlling a sleeving length between the first guiderail piece and the second guiderail piece. The embodiments in the present invention has significantly improve the mounting efficiency of the telescopic electric curtain guiderail.

A curtain remote controller and a method for setting remote control stroke thereof are provided, and the curtain remote controller controls the curtain driving motor through remote-control buttons; the managing buttons are used to set the upper and lower stroke interval of the curtain, so that the curtain moves within the interval and free adjustment of the stroke interval according to specific requirements is achieved. Meanwhile, the curtain remote controller adopts a conversion switch to form the remote control module and the setting module of the curtain remote controller, so that the function modules of the buttons are clearly divided to avoid situations such as the user is confused by too many buttons; it is convenient for users to identify each function module with a simple operation interface; the logical relationship of the curtain remote controller is simplified, and misoperation of the user is avoided.
