Abstract: A clutch switching device for electric rolling doors contains: a housing, a rotating plate, and a shifting bar. The rotating plate is provided in the housing for connecting with the clutch pulling cord. The shifting bar is coupled with the rotating plate and is pulled to drive the rotating plate to move toward a manual mode position or an automatic mode position. The rotating plate has a wrenching portion for matching with a wrench tool so as to wrench the rotating plate. The housing includes a movable fixing element, the rotating plate has a first positioning aperture and a second positioning aperture, such that when the rotating plate is located at a manual mode position, the first positioning aperture aligns and retains with the movable fixing element; when the rotating plate is located at the automatic mode position, the second positioning aperture aligns and retains with the movable fixing element.

Abstract: The present invention relates to an electrical garage door with a secondary power supply, comprising: a garage door mechanism, a driving mechanism, a power receiving device, and a controlling and boosting device. In the present invention, it mainly installs the power receiving device and the controlling and boosting device to the garage door mechanism; therefore, once the city power discontinues to supply power to the controlling device and the driving mechanism of the garage door mechanism, user may connect a car cigarette lighter power cable to the power receiving device and provide a secondary power to the power receiving device, and then the controlling and boosting device can convert the voltage value of the secondary power to a target voltage value, and then the controlling and boosting device outputs the secondary power with the target voltage value for driving the driving mechanism to operate.

Abstract: The present invention discloses a driving machine with a detachable battery for electric garage doors and electric rolling doors, which is electrically driven to open or close an electric garage door or electric rolling door, and which comprises a driving device and a spare power device. The spare power device can be detachably assembled to and electrically connected with the driving device. The spare power device has a rechargeable battery, which provides the driving device with power required to open or close the electric garage door or electric rolling door in electric outage.
