Collapsible clothes hanger structure

Abstract

A collapsible clothes hanger structure includes a frame including a pair of supporting legs and a rail. A rail is secured between the supporting legs. A tent is provided on the frame and the tent covers a portion of the rail. A transmission unit includes a transmission gear meshing with a transmission belt. The transmission gear and the transmission belt are disposed in the rail. Multiple hanging units are movably disposed in the rail in sequence. A motor is connected to and drives the transmission unit in the rail to control the hanging units to slide along the rail. A control unit is coupled with a light sensor, a water drop sensor, and a timer. The control unit collects signals from any of the light sensor, the water drop sensor, and the timer to control the motor and the hanging unit. By the structure, the collapsible clothes hanger is automatically expanded or retracted according to light and rain or the pre-set time.
