ELECTRIC CURTAIN AND DRIVING DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/012214
Kind Code:
A1
Abstract:
An electric curtain and a driving device (1) therefor. The driving device (1) is used for being fixed to curtain cloth (3) so as to drive the curtain cloth (3) to move in the axial direction of a guide rail (5), and comprises: a housing (10); a traveling wheel (12) pivoted to the housing (10) and pressing against the guide rail (5); a driving mechanism (14) assembled in the housing (10) and used for driving the traveling wheel (12) to roll in the axial direction of the guide rail (5); a limiting rolling wheel (17), which has the two ends pivoted to corresponding movable shaft seats (16) and is assembled on the housing (10) by means of the movable shaft seats (16); and elastic members (18) used for elastically pushing the movable shaft seats (16) to enable the limiting rolling wheel (17) to press against the guide rail (5). The traveling wheel (12) and the limiting rolling wheel (17) press against the guide rail (5) from the upper side and the lower side of the guide rail (5) respectively. The traveling wheel (12) and the limiting rolling wheel (17) tightly press against the guide rail (5) from the upper side and the lower side of the guide rail (5) respectively, so that the guide rail (5) is limited, thus guaranteeing that the wheel face of the traveling wheel (12) tightly presses against the guide rail (5) all the time, and achieving stable opening and closing of the curtain cloth (3).
