Driving lever rear portion 622 is rotationally worn in the through hole, driving lever rear portion 622 and turning-bar 61 are rotatablely connected；With direction
Disk 12 rotates, and driving lever front 621 rotates with it, 622 left-right rotation of driving lever rear portion, so that turning-bar 61 is driven to move left and right, band
Left front wheel carrier 21a, off-front wheel frame 21b difference around the pivot a1, pivot a2 rotation are moved, realizes and turns to.Turning machine in the present embodiment
Cost is relatively low for structure.
Above-mentioned perambulator can be children's electric motor vehicle, using left rear wheel 4a and off hind wheel 4b as driving wheel, on left rear wheel 4a
Motor 41 equipped with one for driving it to rotate, off hind wheel 4b are equipped with a motor 41 for driving it to rotate.
It should be noted that: in above-mentioned each pivot, the axial line of each pivot extended in left-right direction is parallel to each other
And horizontal extension, the axial line of each pivot vertically extended are parallel to each other and extend vertically.
The working principle of the perambulator is as follows:
It is tilted to the left when taking children's torso on the seat, 1 two sides unbalance stress of vehicle frame, front rod mechanism 3 connects with after
The four-bar mechanism of linkage 5 can corresponding deformation, allow vehicle frame 1 around central shaft rod 110 rotate and be tilted to the left；When children's body
Body is tilted to the right, and vehicle frame 1 is rotated around central shaft rod 110 and is tilted to the right.
Not when steering wheel rotation 11, vehicle straight trip.When steering wheel 11 rotates, driving lever 62 is rotated with it, and then with turn
It being moved left and right to bar 61, left front wheel carrier 21a, off-front wheel frame 21b are rotated at pivot a1, pivot a2 relative to fore-stock 20 respectively,
The near front wheel 2a and off-front wheel 2b are turned to the left or to the right, and vehicle can turn to the left or to the right.Perambulator in motion, due to seat
The gravity of upper children and the elastic force of hydraulic cylinder, front rod mechanism 3 and the four-bar mechanism of back link mechanism 5 can be strained mutually
Shape, each hydraulic cylinder can accordingly stretch, and vehicle frame 1 and seat opposing front wheels and rear-wheel is allowed to generate the movement of up and down direction.
The vehicle frame 1 of the perambulator can tilt to the left or to the right；Pass through the deformation of the four-bar mechanism of the left and right sides, hydraulic air
Cylinder it is flexible, vehicle frame 1 and children thereon opposing front wheels and rear-wheel can have the displacement of up and down direction in the process of moving, also make
Relatively steady in vehicle motion process, experience effect is preferable, increases interest.
The above embodiments are only for explaining the technical ideas and features of the present invention, is preferred embodiment, purpose
It is that person skilled in the art can understand the content of the utility model and implement accordingly, can not be limited with this practical
Novel protection scope.Equivalent transformation or modification made by all Spirit Essences according to the present utility model, should all cover in this reality
Within novel protection scope.
