Abstract: A driving mechanism drives a vehicle window to move up and down. The driving mechanism includes a housing, and a driving assembly and a transmission assembly. The driving assembly is engaged with the transmission assembly. The driving assembly is partially received in the housing. The transmission assembly includes a first transmission member connected to the driving assembly, a second transmission member engaging with the first transmission member, and a planetary gear set. The planetary gear set connects to an external device. The driving assembly drives the first transmission member which in turn drives the second transmission member to rotate. The second transmission member drives the planetary gear set which in turn drives the vehicle window to move.

Abstract: A power tool includes a main body and a working portion. The working portion is rotatably coupled to the main body. A single phase brushless motor is mounted in the main body to drive the working portion to rotate bidirectionally. In comparison with a traditional motor, the single phase brushless motor make the power tool has a reduced size and reduced cost while ensuring the stable performance.

Abstract: An actuator and its clutch are provided. The clutch includes a driving shaft; a mounting base fixed to the driving shaft for rotation with the driving shaft; a connecting base for connecting with a load, the connecting base including fingers surrounding an outer circumference of the driving shaft; resilient member including a resilient member, the resilient member having two ends respectively fixed to the mounting base and the connecting base, the resilient member surrounding an outer circumference of the connecting tabs. When a rotation speed of the driving shaft is greater than a rotation speed of the connecting base, an inner diameter of the resilient member gradually decreases so as to gradually couple the coupling portion with the driving shaft, such that the rotation speed of the coupling portion gradually approaches or reaches the rotation speed of the driving shaft.

Abstract: An actuator for a vehicle door lock mechanism has a motor, a first gear, a second gear and a third gear. The motor has a shaft to which the first gear is connected. The motor rotates the first gear, which in turn drives the second gear and the third gear. A non-tooth part is formed on the second gear. A projection is formed on the third gear. Stops are arranged for stopping rotation of the third gear. When the second gear rotates to a position where the non-tooth part corresponds to the third gear, the projection is spaced from one stop by an angle. When the second gear rotates further, the gears re-mesh and the third gear rotates till the projection contacts the stop.

Abstract: A driving apparatus for a washing machine includes a single-phase outer rotor brushless motor and a driving wheel. The motor drives the driving wheel and includes a stator and a rotor. The stator includes a stator core and windings wound around the stator core. The rotor includes a rotor yoke, and a permanent magnet. An inner surface of the permanent magnet and an outer surface of a tooth tip are opposed to each other and define an uneven gap there between for allowing the rotor to rotate relative to the stator. A radial width of the gap associated with each magnetic pole progressively increases from a center portion toward circumferential ends of the magnetic pole, and a radial width of the gap associated with each magnetic pole is symmetrical with respect to a center axis of the magnetic pole along the circumferential direction.

Abstract: A drive apparatus for an electric bike includes a hollow housing body, an internal ring gear fixed to the housing body, and a main shaft. At least two motor units are mounted in the housing body. Each motor unit includes a support bracket and a number of motors mounted on the support bracket. Each motor drives the internal gear through a transmission mechanism to rotate the housing body about the main shaft. The motors share one controller. Peaks of the motor cogging torque can be staggered.

Abstract: An actuator for adjusting a seat includes a motor, a gear-box, and an output member. The gear-box includes a casing accommodating a two stage gear train connecting the motor to the output member. The gear train has a first and second transmission mechanisms. The first transmission mechanism includes a worm on a shaft of the motor, and a worm wheel meshed with the worm. The second transmission mechanism is a movable teeth gear transmission mechanism and has an eccentric wheel that rotates with the worm wheel, an internally toothed ring gear fixed to the casing, a fluted disc with radial grooves formed in its outer periphery, and rollers mounted in the radial grooves. The eccentric wheel drives the rollers to mesh with the ring gear to rotate the fluted disc, to drive the output member.

Abstract: The planetary gear train includes a first sun gear driven by the motor, a first ring gear, a first carrier, and a plurality of first planetary gears arranged at one side of the first carrier and meshing with the first sun gear and the first ring gear. The first sun gear, first planetary gears and first ring gear are helical gears so that meshing surface is increased. Helical teeth formed on an inner surface of the first ring gear mesh with the helical teeth of the first planetary gears. Therefore, the operation is stable and the noise is low. The planetary gears are made of plastic to further decrease the noise. The first ring gear is made by sintered powder metallurgy.
