Claim 0:
1. An intelligent electric wheel hub comprising a gear motor, a flywheel mechanism and a cylindrical freehub body; wherein
the intelligent electric wheel hub further comprises a cylindrical battery pack, a wheel hub left end cover, a cylindrical wheel hub housing, a wheel hub left half shaft, a wheel hub right half shaft, a riding state sensing device and a controller panel; wherein
the freehub body is sleeved on the wheel hub right half shaft by supporting bearing; wherein
the wheel hub left end cover is sleeved on the wheel hub left half shaft by supporting bearing and is fixedly connected to the left end of the wheel hub housing; wherein
the flywheel mechanism comprises an outer flywheel ring and an inner flywheel ring that are matched by ratchet-pawl and nested by supporting bearing, the inner flywheel ring fixedly connected to the freehub body, and the outer flywheel ring fixedly connected to the right end of the wheel hub housing to form a wheel hub inner cavity accommodating the gear motor and the battery pack; wherein
a motor housing of the gear motor is fixedly connected to the wheel hub left half shaft and the wheel hub right half shaft, and the gear motor is connected to the wheel hub left end cover through a decelerating mechanism to drive the wheel hub left end cover to rotate; wherein
the battery pack is fixedly sheathed outside the motor housing; wherein
the battery pack is electrically connected to the controller panel to power the controller panel; wherein
the controller panel comprises a riding state sensing device and a processor, a motor driving module, wherein the riding state sensing device comprises a multi-pole magnetic ring rotating with the freehub body, and a Hall sensor sensing the rotation direction of the multi-pole magnetic ring, the Hall sensor signal connected to the processor, the motor driving module connected to the processor, and the motor driving module electrically connected to a coil of the stator, wherein the processor controls the motor driving module to drive the gear motor to run.
