A telescopic curtain guide rail includes an inner rail, an outer rail and a transmission unit. The inner rail is embedded in the outer rail, the transmission unit includes a driving wheel connected with a motor, a driven wheel, two fixed pulleys and a conveyor belt. The driving wheel and the driven wheel are located at two ends of the curtain guide rail, the two fixed pulleys are respectively located at other ends of the inner rail and outer rail. The driving wheel and one fixed pulley are located at two ends of the inner rail or outer rail, the conveyor belt is wound on the driving wheel, the driven wheel and the two fixed pulleys. A telescopic operation of the curtain guide rail can change positions of the two fixed pulleys simultaneously, and the curtain guide rail is simple to use and has a small occupied area.

The present application provides a driving device including: a driven wheel configured to connect a pulling rope; a driving mechanism configured to drive the driven wheel to rotate; wherein the driving mechanism includes a driving motor, an output shaft, and a transmission assembly, the transmission assembly is connected between the driving motor and the output shaft, and the output shaft is connected to the driven wheel; when the output shaft is in a first state, the output shaft is coupled to the driven wheel and the transmission assembly respectively to form transmission connection; when the output shaft is in the second state, the output shaft is decoupled from the driven wheel and/or the transmission assembly to disconnect the transmission connection. The present application further provides an electric curtain having the driving device.

A drive assembly for moving a curtain of a vehicle includes a drive rack, an idle gear engaged with the drive rack, a motor assembly and an actuator. The motor assembly includes a drive gear engageable with the idle gear, a gearbox connected to the drive gear, and a motor connected to the gearbox for driving the drive gear. The actuator is for moving the motor assembly between an idle position, wherein the idle gear is idle, and a drive position, wherein the drive gear is engaged with the idle gear for driving the idle gear. When the motor assembly is in the drive position, the idle gear is drivable by the motor to move the idle gear along the drive rack. One of the drive rack and the idle gear is mountable on the curtain so as to move the curtain between a first and a second position.

A shower curtain closure device for automatically closing a shower curtain includes a housing having a front side, a back side, and a peripheral wall extending therebetween, defining an interior space. The front side has a shower rod recess therein that is configured to receive a portion of a shower curtain rod. A spool is positioned within the interior space. A cord having a spool end and a clip end is coupled to the housing. The spool end is attached to the spool and the cord is wrapped around the spool. The spool rotates to wrap and unwrap the cord, such that the cord retracts into and extends from the housing. A curtain clip is attached to the clip end that can removably engage a shower curtain ring. A motor is positioned within the interior space. The motor is coupled to the spool, rotating the spool to retract the cord.
