ABSTRACT:
A collapsible car shield structure comprises a main body, a primary worm, a number of worm gears, a number of large belt pulleys, a number of small belt pulleys, a number of primary legs, a number of secondary legs, and a number of driving belts. The main body is formed with a number of slots each having at least two upstanding side plates. The primary worm is centrally pivotally mounted on the main body. The large belt pulleys are respectively firmly fixed on the upstanding side plates of the slots of the main body. The primary leg includes a proximal end and a distal end in which the proximal end is pivoted on the upstanding side plates of the main body by a short shaft. The worm gear is firmly secured to the proximal end of the primary leg and engages with the primary worm. The secondary leg includes a proximal end and s distal end, in which the proximal end is firmly secured with the small belt pulley and is pivoted on the distal end of the primary leg. The small belt pulley and the large belt pulley are coupled by the driving belt, so that when the primary worm drives the worm gears to swing the primary legs, the secondary legs swing relative to the primary legs to quickly and easily expand or withdraw the collapsible car shield structure.
