Document Type and Number:
WIPO Patent Application WO/2020/258054
Kind Code:
A1
Abstract:
Provided is a roller shutter driving device, comprising drivers (7) arranged in a winding drum (5), a shaft rod (8) inserted into the winding drum (5), and a transmission mechanism (9). Each of the drivers (7) comprises a housing (70) fixed relative to the winding drum (5), a rotation power member (71) arranged in the housing (70), a driving gear (73) fixed to an output shaft (72) of the rotation power member (71) and coaxial to the output shaft (72), and a first transmission gear (74) arranged on the housing (70) in a pivoting manner and meshing with the driving gear (73), and the roller shutter driving device is provided with at least two drivers (7) that are sequentially and linearly connected, wherein the driving gear (73) of one driver (7) adjacent to the transmission mechanism (9) is in transmission fit connection with the transmission mechanism (9), and the driving gear (73) of each of the other drivers (7) meshes with the first transmission gear (74) of the adjacent driver (7) on one side, close to the transmission mechanism (9), of the drivers. The roller shutter driving device can output a good amount of power to the outside, is convenient to assemble, and can realize combined adjustment of the driving force.
