It is rotated counterclockwise therewith to brace rod 64, the second cardan universal joint component 66 and gear 63, and then rack gear 62 moves right, Zuo Heng
Bar 61a and right cross bar 61b move right, and left front wheel carrier 21a, off-front wheel frame 21b distinguish around the pivot a1, pivot a2 turns counterclockwise
Dynamic, the near front wheel 2a and off-front wheel 2b are turned to the left, and vehicle turns to the left.Similarly, when steering wheel 11 rotates clockwise, vehicle is to the right
It turns to.
Children's electric motor vehicle in motion, due to the gravity of children and the elastic force of hydraulic spring grease cup on seat 12, the four of left side
Link mechanism and the four-bar mechanism on right side meeting corresponding deformation, each hydraulic spring grease cup and direction brace rod 64 can accordingly stretch,
Vehicle frame 1 and 12 opposing front wheels of seat and rear-wheel are allowed to generate the movement of up and down direction.
The vehicle frame 1 of the children's electric motor vehicle can tilt to the left or to the right；By the deformation of the four-bar mechanism of the left and right sides,
The rotation of rear connecting rod 51, hydraulic spring grease cup and direction brace rod 64 it is flexible, vehicle frame 1 and children thereon can travel
Opposing front wheels and rear-wheel have the displacement of up and down direction in the process, also make in vehicle motion process relatively steadily, experience effect is preferable.
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.
