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.

Disclosed is a double-drum type curtain drum module, comprising a shell base having two compartments, a first guide wheel, a second guide wheel, an auxiliary cord rotator installed in a first compartment, and two cord drums installed in a second compartment. At least two reinforcing bars in parallel are formed in the first compartment. A plurality of first wheel-connecting grooves are formed on the reinforcing bars for installing the first guide wheel. The second compartment has a plurality of second wheel-connecting grooves formed on a bottom surface of the shell base for installing the second guide wheel. A connecting channel is formed between the reinforcing bars and exposed from the bottom surface of the shell base. The connecting channel extends into the second compartment for coupling the first wheel-connecting grooves and the second wheel-connecting grooves. A control cord reset opening is formed from the first guide wheel to a first end of the connecting channel to align between the curtain auxiliary cord access holes. A control cord transferred opening is formed from the second guide wheel to a second end of the connecting channel. Accordingly, what is solved is the rubbing issue of conventional control cord against the topmost curtain sunshade blade caused by conventional control cord being oblique to the curtain auxiliary cords adjacent to the control cord access holes.

The present invention discloses a retractable curtain rail. including a guiding rail body, wherein the guiding rail body includes an external guiding rail, an internal guiding rail and a transmission case, the internal guiding rails are configured to be two pieces and respectively inserted at both ends of the external guiding rail, which is connected with the internal guiding rails by means of a connector, and the transmission cases are configured to be two pieces and respectively fixed on the ends of the two internal guiding rails, a driving wheels is movably connected inside the two transmission boxes, respectively, a transmission belt is connected between the two driving wheels, the transmission belt is fixedly connected with two curtain heads. The retractable curtain rail has following beneficial effects.

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 curtain structure 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 motorized window covering system is presented having a rotatable drive element having a guide structure and a plurality of idler attachment elements and at least one drive element positioned over the rotatable drive element. A motor is connected to the rotatable drive element and controls operation of the window covering. An external battery tube assembly is connected by a conduit to the rotatable drive element and is configured to provide power to the motor. The external battery tube assembly includes a switch and controls operation of the motorized window covering. When pulled or lifted the external battery tube assembly initiates movement, stops movement or reverses movement of the motor. In this way, the system provides a unique way of controlling operation of a motorized window covering.

The present invention relates to an intelligent motorized curtain mechanism, wherein a first mounting box, a second mounting box, a bead chain length adjustment mechanism and a bead chain are provided, and a power control mechanism and a master drive mechanism are fixedly installed inside the first mounting box. The power control mechanism is arranged to drive the master drive mechanism, which forms a synchronous belt connecting with the bead chain through the slave mechanism and enables the master drive mechanism to move the bead chain.

A ribbon-type device effects undulation of a curtain for gathering the same in the vertical or horizontal direction. A functional unit comprises two tapes of fabric, each of which extends in an undulating manner to form a plurality of alternating positively and negatively curved arcs. An arc of positive curvature of a first fabric tape is set so as to oppose an arc of negative curvature of a second fabric tape and an arc of negative curvature of the first fabric tape is set so as to oppose an arc of positive curvature of the second fabric tape. The two fabric tapes are joined to each other at each transition between an arc of positive curvature and an arc of negative curvature by means of tie-off stitching (tie-offs). A plurality of such tie-offs accommodate a pull cord of a curtain.
