Electric motor units.
In one embodiment of the invention, wheel hub motor 100 has what at least one drive hub 20 rotated
Electric motor units.In the present embodiment, wheel hub motor 100 has the electric motor units that a drive hub 20 rotates, and is the first electricity
Machine unit 30.
In one embodiment of the invention, each electric motor units includes at least be mutually arranged in correspondence with
Individual stator and at least one rotor.In the present embodiment, the first electric motor units 30 includes the first stator 31 He of corresponding setting
The first rotor 32.
In one embodiment of the invention, wheel hub 20 is pivotally connected to wheel shaft 10 phase；It is to say, at wheel
During hub motor 100 operating, wheel hub 20 rotates, and wheel shaft 10 does not rotates.As it is shown in figure 1, in the present embodiment, wheel hub 20 with
A set of bearing 11 it is provided with between wheel shaft 10.
In one embodiment of the invention, the both sides of wheel shaft 10 respectively have an end, one end therein
It is fixedly installed the first end cap 41.
In the present embodiment, about the secure fit between wheel shaft 10 and the first end cap 41, such as Fig. 1 and as indicated with 2, first
End cap 41 has the axle sleeve 410 coordinated with wheel shaft 10, and wheel shaft 10 through the axis hole in axle sleeve 410 and is socketed solid with axle sleeve 410
Fixed.In the present embodiment, the first end cap 41 is vertically arranged with wheel shaft 10.
In one embodiment of the invention, at least one stator of the first electric motor units 30 is fixedly installed in
On one end cap 41, at least one rotor of the first electric motor units 30 is fixedly installed on wheel hub 20；It is to say, rotor is with wheel hub
20 rotate together with, and stator is fixed on the first end cap 41, thus fix relative to wheel shaft 10.
In the present embodiment, the first stator 31 of the first electric motor units 30 by coaxial and fixing in the way of be installed on the first end

300 have folded state and deployed condition relative to wheel hood 200；Fixed one ride respectively on the both sides inwall of wheel hood 200
Plate stop part 50, when pedal 300 is in deployed condition, the side end near wheel hood 200 of pedal 300 upwards supports
It is held in pedal stop part 50, thus the stress on pedal 300 is delivered to pedal stop part 50, due to pedal stop part
50 fixing with wheel hood 200 are connected, and therefore, the stress on pedal 300 can disperse be delivered to by pedal stop part 50
In wheel hood 200, preferably pedal 300 can be maintained deployed condition；Furthermore, in addition to the dispersion of stress is transmitted,
Active force between pedal 300 and wheel hood 200 is above-below direction, is possible to prevent to take turns hood 300 (such as metal shell)
It is deformed in the lateral direction.
Seeing Fig. 4, pedal stop part 50 has the stopper protrusion 51 extended laterally, when pedal 300 is in expansion
During state, the side end near wheel hood 200 of pedal 300 is upwards held in stopper protrusion 51.
In the present embodiment, pedal stop part 50 can be one-body molded with wheel hood 200 (inwall).
In the present embodiment, two, the left and right pedal stop part 50 on the both sides inwall of wheel hood 200 is respectively with first
End cap 41 and the second end cap 42 realize being removably secured connection by fixing connector (not shown)；Fixing connector can
To use the securing member of such as screw etc.It is to say, be only installed in two, the left and right pedal of wheel hood 200 both sides inwall
Block piece 50 fixes connector and the first end cap 41 and dismountable fixing connection of the second end cap 42 by one respectively, thus realizes
Dismounting between wheel hood 200 and wheel hub motor 100 and assembling.
In the present embodiment, electric motor car is Self-balance electric vehicle.
