Document Type and Number:
WIPO Patent Application WO/2021/027522
Kind Code:
A1
Abstract:
A press type spring switch mechanism and an electric/manual switchable window opener thereof. The window opener comprises a motor (100). An output shaft of the motor (100) is provided with a first worm gear mechanism (201, 202); the first worm gear mechanism (201, 202) drives a first gear (301), a second gear (302) and a third gear (303) to rotate by means of a transmission shaft; the second gear (302), a mode switch (400) at the upper part, and a spring (500) at the lower part constitute a press type spring switch mechanism, capable of carrying out switching of an electric/manual mode; a manual mode rotation shaft (900) rotatably matching the third gear (303) has an upper part designed as a cuboid shape, which can match a corresponding handle to rotate, so as to control expansion and contraction of a chain; under an electric mode, the mechanism normally controls transmission; under a manual mode, the mode switch (400) is pressed, at this time, the handle is used for rotating the manual mode rotation shaft (900) to control opening and closing of a window, and the mode switch (400) is pressed again to return to transmission under the electric mode.
