SUNBLIND DRIVING APPARATUS HAVING RETURNING FUNCTION OF DRIVING WHEEL MEMBER

摘要

The present invention relates to the sunshade driving device comprising that: a returning function of a manually driving module (410) is actuated by a ball chain or a rotating string; a rotating shaft (421) is attachable/detachable to the power drive means or the rotating shaft stopping means separated from a manual driving module; at least one pick-up member (452, 452') to directly drive the sunshade rotating shaft or driving the rotating shaft (421) by the manual drive module (410); a wheel driving member (415') having a manual pulley (415a) or a manual driving wheel (412b) being fitted the ball chain or rotating string; wherein the wheel drive member (415') will be engaged to the manual rotating wheel (412b) and the manual pulley (415a) for rotating together in one direction, and the wheel driving member (415') will disengaged the manual rotating wheel (412b) and the manual pulley (415a) for independently rotating each other in opposite direction activated by a bi-directional driving clutch (415b).
