Document Type and Number:
WIPO Patent Application WO/2019/183822
Kind Code:
A1
Abstract:
A differential gear drive apparatus, a stabilizing mechanism, a pan-tilt apparatus, and a photography device. The stabilizing mechanism (20) comprises a differential gear set (4), a first motor (2), a second motor (3), and a movement transformation component. The differential gear set (4) comprises a first axle shaft gear (41) and a second axle shaft gear (42) provided opposite to each other, and a first planetary gear (43) engaged with the first axle shaft gear (41) and the second axle shaft gear (42), separately. The second motor (2) is connected to the first axle shaft gear (41). The second motor (3) is connected to the second axle shaft gear (42). The first planetary gear (43) can not only perform spinning motion, but also perform revolution motion around the first axle shaft gear (41) and the second axle shaft gear (42). The motion transformation component is connected between a load and the first planetary gear (43) for transforming the revolution motion thereof into a motion of the load in a first direction, and transforming the spinning motion of the first planetary gear (43) into a motion of the load in a second direction.
