When advance, driving mechanism 5 is opened that time of starting, the motion principle of front-wheel is as follows: due to the friction of tire 12 and ground,
Wheel hub 1 maintains the original state i.e. stationary with tire 12, and eccentric gear 2 is moved up along ring gear 11 at this time.And due to
Eccentric gear 2 is limited in eccentric limit space 35 by wheel shell 3, so as eccentric gear 2 moves up, bias limit
Space 35 can also move up, and then rotate with motor car wheel shell 3.At this point, since toy car needs to advance, so wheel shell
3 be to rotate clockwise, and at the same time, vehicle frame is moved up with eccentric gear 2, and then limited block 41 can be along limit sliding chutes 32
It moves up, slides to the second limit point 322 from the first limit point 321；When limited block 41 is moved to the second limit point 322, vehicle
Hub cap 3 just stops operating, and eccentric gear 2 drives the rotation of ring gear 11 in turn, to drive vehicle wheel rotation, and then drives
Toy car marches forward.Hereafter, it is limited due to the gravity of vehicle frame itself so vehicle frame can move down during wheel advances
Position block 41 can come back to the first limit point 321 again.The motion principle of rear-wheel is as follows: the motion principle and front-wheel substantially one of rear-wheel
Sample, but unlike, eccentric gear 2 is moved down along ring gear 11, and band motor car wheel shell 3 rotates, and then drives limit
Block 41 moves down.But since limited block 41 has been at the first limit point 321, so limited block 41 can not be still further below
It is mobile, so that wheel shell 3 can not also rotate, so eccentric gear 2 will not move down, but drive ring gear 11
Rotation, so that rear-wheel be driven to advance.
Secondly, wheel hub 1 is with tire 12 since inertia also maintains originally when toy car inverts suddenly while advancing
The trend of advance.Due to the powerful reactive torque that driving mechanism 5 exports, eccentric gear 2 can be along ring gear 11 from bottom to top
It is mobile, to be rotated counterclockwise with motor car wheel shell 3；At the same time, vehicle frame rear end moves up, and shows the state of tilting,
Also, limited block 41 is moved along limit sliding chutes 32 to the second limit point 322 from the first limit point 321.Front-wheel during this
The movement of rear-wheel is similar when movement starts as described above, so the front end of vehicle frame will not tilt.
Furthermore when toy car brakes suddenly while advancing, driving mechanism shuts down suddenly, the eccentric gear of rear-wheel
2 shut down, and wheel hub 1 is rotated counterclockwise since inertia still maintains original forward travel state.Again due to eccentric gear 2 with it is interior
Gear ring 11 engages, so wheel hub 1 will drive eccentric gear 2 and move up, while eccentric limit space 35 also moves up therewith,
So that wheel shell 3 rotates counterclockwise, 4 rear end of vehicle frame is tilted and limited block 41 is limited along limit sliding chutes 32 from first
Point 321 slides to the second limit point 322.Same principle analysis front-wheel, front-wheel does not tilt at this time.

The other end of 1 affixed point 711, second connection end 72 and vehicle frame 4 is fixedly linked to form the second affixed point 721.The fender bracket 7 is main
It plays a protective role, protection toy car is against damages, to extend the service life of toy car.Secondly, fender bracket 7 is preferably
Arc；When toy car inverts suddenly, since toy car also keeps the inertia of original advance, in addition rear-wheel tilts, so toy
Vehicle meeting tip forwards, i.e. toy car turn upside down.If adding arc fender bracket in toy car upper end, toy car is just
It can use inertia, along arc, and be flipped back to and, so that the rolling of toy car is realized, so that the operation of toy car is more
Sample, interest are stronger.Further, the first connecting pin 71 and the outer edge of the car body close to the first connecting pin 71 are tangent,
And/or the outer edge of the car body of second connection end 72 and close second connection end 72 is tangent.In this way, when car body rolling,
