Abstract:
1. An improved structure for car cover comprising: a main unit with a compartment and a conduit at each corner of the main unit to provide the compartment with external connectivity; a transmission component that can be driven by external power supply and is located inside the compartment of the main unit and has at least one drive unit that can be driven by the power supply; multiple passive components located at the peripheral of the transmission component inside the compartment, with at least one driven unit and one wire duct on each passive component and each driven unit being able to connect with the drive unit of the transmission component to move synchronously and wire duct being wrapped around by a flexible elastic cable that has an active end to pass through a conduit to the outside of the compartment; multiple link mechanisms provided in each conduit at each corner of the main unit, each mechanism having multiple longer first links and multiple shorter second links, wherein each longer first link and each shorter second link forming a pair of link mechanism in a repetitive bending fashion, being linked for extension and shrinkage of the car cover, through connecting one end to the main unit and the other end to an active end of different flexible elastic cables, enabling synchronous movement of the link mechanism by every flexible elastic cable and allowing extension and shrinkage in length, and a soft piece of shield that is attached to the multiple link mechanisms and able to varies with the length through extension and shrinkage of the multiple longer first links and multiple shorter second links of the multiple link mechanisms to change the coverage area.
