Description

The body frame structure for automotive of child's tricycle

Technical field

The utility model relates to a kind of body frame structure for automotive of child's tricycle, refers to a kind of body frame structure for automotive that is applied to have the child's tricycle of Shock absorber especially.

Background technology

Child's tricycle is because the purpose that has body-building and play can make children reach the effect of body-building when driving, so favored by the head of a family.The present existing child's tricycle structure of detailed sight, it is fixed vehicle frame, is not provided with to supply folding structure for vehicle frame folding, and saves placing room with this, and real is blemish in an otherwise perfect thing.Add, three-wheel vehicle now drives more comfortablely for making, and it is greatly more than implementing in conjunction with Shock absorber on the vehicle frame.Yet it is but bulky far beyond the three-wheel vehicle of conventional fixed that a new generation has the structure of child's tricycle of Shock absorber, and therefore, the three-wheel vehicle structure that this kind has shock-proof effect more needs folding design, is beneficial to reduce the volume after placing.

The utility model content

The purpose of this utility model is to provide a kind of body frame structure for automotive of Foldable child three-wheel vehicle.

For achieving the above object, technical solution of the present utility model is: a kind of body frame structure for automotive of child's tricycle, comprise handle, vehicle frame, seat and Shock absorber, handle is plugged in the vertical tube of vehicle frame front end with its vertical tube, vehicle frame is divided into forward and backward two sections of mutual pivot joint, and the seat front end is articulated in the vehicle frame leading portion, wherein:

This seat back segment articulates an end of Shock absorber, and the other end of Shock absorber then is articulated in the vehicle frame back segment; And vehicle frame leading portion rear end is provided with the protruding tip in addition and has the lug of knock hole, and vehicle frame back segment front end then correspondence is provided with a horizontal tip block and and draws button; The protruding tip and horizontal tip block keep off mutually, draw button to wear in the knock hole that is butted on lug.

After adopting such scheme, because the utility model is divided into vehicle frame forward and backward two sections of mutual pivot joint, when folding, as long as draw button, make it break away from knock hole, the back segment of vehicle frame can be folded by relative leading portion, fold volume thereby dwindle, and then reach the effect of simplifying its storage and transportation volume, and this structure operation is convenient.
