And control device, the axletree 13 has two, and the two ends of stator axis 12 with external rotor electric machine 8 are fixedly linked respectively, wheel 1 with
The rotor 11 of external rotor electric machine 8 is fixedly linked, and the outer side surface of the chuck 2 is provided with helicla flute 15, and the middle part of chuck 2 passes through bearing
On axletree 13, the positioning disk 5 is the annular disk being fixedly linked with wheel 1, is rotated with wheel 1, positioning disk 5
Multiple pilot holes 14 are provided with, the pilot hole 14 is radial direction through hole, and multiple pilot holes 14 uniformly divide along the circumferencial direction of positioning disk 5
Cloth, described one end of support bar 4 forms slidably secondary, the other end of support bar 4 in pilot hole 14 with corresponding pilot hole 14
Provided with the claw 3 that can be slided on chuck 2 in helicla flute 15；
The commutator 6 is enclosed in the stator axis 12 of external rotor electric machine 8, and the one end of commutator 6 passes through the first spline 16 and card
Disk 2 remains engaged transmission, and the other end is provided with the second spline 17 that can be engaged with the rotor 11 of external rotor electric machine 8, commutator 6
Can along stator axis 12 axially free slip, between chuck 2 and commutator 6 be provided with spring 7 and electromagnet 9, external rotor electric machine 8
Rotor case is provided with corresponding with electromagnet 9 and opposite polarity permanent magnet 10, and the electromagnet 9 passes through control device control
Dead electricity is obtained, the commutator 6, toward the movement of the direction of external rotor electric machine 8, is nibbled under the effect of spring 7 with the rotor 11 of external rotor electric machine 8
Close, it is electric by controlling electromagnet 9 to obtain, commutator 6 can be controlled to be moved toward the direction of chuck 2 so that commutator 6 and external rotor electric machine
8 rotor 11 is separated.
Lubricating grease is provided between the support bar 4 and pilot hole 14, prevents foreign matter from entering while lubrication is provided.
The end of support bar 4 is connected with claw 3 using spherical pair.
The particular number of pilot hole 14 on the positioning disk 5 can be selected according to the size of wheel 1, it is considered to complicated
Property, 3-16 are typically chosen, pilot hole 14 is uniformly distributed on positioning disk 5, the inner ring of the positioning disk 5 is more than the diameter of chuck 2.

Operation principle：
During electric car normal work, the dead electricity of electromagnet 9, in the presence of spring 7, the one end of commutator 6 is nibbled with chuck 2 all the time
Close, the other end is engaged with the rotor 11 of external rotor electric machine 8, and positioning disk 5 is fixedly linked with wheel 1, wheel 1 and external rotor electric machine
8 rotor 11 is fixedly linked, therefore positioning disk 5 and the synchronous rotary of chuck 2, and support bar 4 does not occur relatively radially outside with chuck 2
It is mobile；
When electric vehicle parking car locking, electromagnet 9 is controlled to obtain by control device electric, electromagnet 9 and permanent magnet produce phase
Repulsion compression spring 7 so that commutator 6 is moved toward the direction of chuck 2, commutator 6 is separated with the rotor 11 of external rotor electric machine 8, changed
Remain engagement to device 6 and chuck 2, chuck 2 under the drive of commutator 6 no longer as external rotor electric machine 8 rotates, this
When positioning disk 5 continue to rotate in the case where the rotor 11 of external rotor electric machine 8 drives, therefore the support bar 4 in the pilot hole 14 just with
Chuck 2 relatively rotates and stopped after a few, and the claw 3 of the end of support bar 4 is on chuck 2 in the rotary course of helicla flute 15, card
Pawl 3 along chuck 2 with being constantly moved outwards, and the support bar 4 being connected with claw 3 stretches out also along outer move of pilot hole 14, stretches out
Support bar 4 outside wheel hinders wheel 1 normally to rotate on patch ground, reaches antitheft purpose.
Control external rotor electric machine 8 to rotate the number of turns by control device, support bar 4 can be controlled to be rotated relative to chuck 2 and enclosed
Number, so as to control support bar 4 from the length outside the stretching of pilot hole 14.
Protection scope of the present invention is not limited to the above embodiments, it is clear that those skilled in the art can be to this hair
It is bright to carry out various changes and deform without departing from scope and spirit of the present invention.If these are changed and deformation belongs to power of the present invention
