Title:
DRIVING DEVICE, OPERATION METHOD THEREFOR, LASER MEASUREMENT DEVICE, AND MOBILE PLATFORM
Document Type and Number:
WIPO Patent Application WO/2018/176292
Kind Code:
A1
Abstract:
A driving device comprises: a rotor assembly, rotating around a preset rotating shaft; a stator assembly, used for driving the rotor assembly to rotate around the rotating shaft; and at least one positioning member, used for limiting the rotation of the rotor assembly that uses the rotating shaft as the center. The positioning member comprises a rotating portion, a fixing portion, and a rolling body. The rotating portion is coupled to the fixing portion by means of the rolling body, so that the rotating portion rotates relative to the fixed portion. The rotating portion can move in the direction of the rotating shaft relative to the fixing portion, so that the rotating portion and the fixing portion jointly press against the rolling body when a push force is applied to the rotating portion.
