The embodiments of the present disclosure effectively solve the problems resulting from the use of magnetic separation in realizing engaging and disengaging functions of an existing clutch.

The present invention has provided a system and method for controlling an electric curtain, which comprises a remote controller end and a curtain end; the remote controller end comprising a first processor, a radio frequency transmitting module, and a button module; the button module and the radio frequency transmitting module are both in electrical connection with the first processor; the curtain end comprises a second processor, a curtain motor, and a radio frequency receiving module; the curtain motor and the radio frequency receiving module are both in electrical connection with the second processor, and the remote controller end further comprises a first NFC communication module in electrical connection with the first processor, and a second NFC communication module with a curtain motor ID; the first NFC communication module and the second NFC communication module are in communication connection, proving the efficiency of the matching of the electric curtain control system.

Provided is an extendable rail, comprising a main rail and an auxiliary rail arranged in parallel with the main rail, the main rail is shifted in longitudinal direction relative to the auxiliary rail, wherein the main rail is configured with a driving wheel and a first reverse wheel; the auxiliary rail is configured with a second reverse wheel, a first guiding wheel and a second guiding wheel arranged inside; a belt loop with fixed length wraps around the driving wheel, the first reverse wheel, the first guiding wheel, the second reverse wheel, the second guiding wheel, and the driving wheel in turn. The total length of the extendable rail can be adjusted according to the practical needs of consumers by adjusting the length of the overlapped area of the main rail and the auxiliary rail, which provides easy adjustment, high universal applicability and operation performance without size customization.

An electric curtain track structure includes a guiding track assembly, a first actuator, a transmission assembly and a decorative assembly. The guiding track assembly includes a guiding track main body having first and second bending sections opposite from each other. The first actuator is installed on the first bending section. The transmission assembly includes a transmission cable and first hooks. The transmission cable is inserted into the guiding track main body and driven by the first actuator to move along the guiding track main body. The decorative assembly includes a decorative panel and heads. The decorative panel is attached onto an outer side of the guiding track main body, and two ends of the decorative panel protruded out of the guiding track man body for the decorative heads to correspondingly install on an outer side of the first and second bending sections. Consequently, the overall appearance thereof is improved.

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.

An electric guide rail type conveying system comprises a driving motor, a guide rail, a main transmission case, an auxiliary transmission case, a conveying member, and a moving trolley. Both ends of the conveying member are elastically deformably wound on the first rotating member and the second rotating member of a main transmission case body in two opposite winding direction. Before installation, the conveying member is basically wound on the first rotating member and the second rotating member. When a relative outer portion of the conveying member wound on the first rotating member is separated from the rotating member, a first elastic resilience opposite to one of the two opposite winding direction is generated; with the increase of a portion, separated from the first rotating member, of the conveying member, the first elastic resilience will increase; otherwise, the first elastic resilience will decrease.

A device for moving objects by a driving cable. The device features two cable spools enabled to wind and unwind the cable on both sides. A remote cable pulley is arranged for guiding, at a remote location (X), the cable. The cable spools are arranged to exert, by means of constant torque springs, a cable pretension force in a direction (T) contrary to the unwinding direction (U) of the spools. Electric driving means are provided to be coupled either to the one or to the other cable spool, thus causing the cable to move from the one to the other cable spool or reversely, in order to move said one or more objects connected to the cable, or to be disengaged from both cable spools in order to enable manual operation of said one or more objects connected to the cable.
