Description

Folding tricycle

Technical field

The present invention relates to a kind of tricycle, be specifically related to a kind of folding tricycle.

Background technology

Children's tricycle is the normally used toy of child, at present, on market, also occurred that children's three-wheel that some can be folding voluntarily, but existing children's three-wheel voluntarily can only be folding at bicycle front fork and vehicle frame place, such folding children's tricycle still occupies larger space after folding, generally compared with the boot of roadlice, can not put into, the rear-box of some automobiles is larger, but just cannot put into again other article after putting into existing folding children's tricycle, existing folding children's tricycle is placed can occupy no small space at home equally.

The patent No. is that CN101357657 discloses a kind of folding children's three-wheel vehicle, its objective is that handlebar can fold, but the folding meeting of normal time of handlebar causes handlebar skew, and cause at child's handlebar in driving procedure and be offset suddenly, will inevitably cause child injured, so must fold in other positions of child's bicycle, make bicycle should save space, can guarantee the performance that it is stable again.

Summary of the invention

The technical problem to be solved in the present invention has: the three-wheel vehicle of the prior art large shortcoming that takes up room.

In order to solve the problems of the technologies described above, the invention provides a kind of folding tricycle, comprise front fork, vehicle frame and saddle, front fork lower end is provided with front-wheel, front fork upper end is provided with the handlebar that can control front-wheel steering, thereby be provided with on front-wheel for folding tricycle user pin, step on and controls the foot drive device that folding tricycle travels, and vehicle frame front end is fixedly connected with front fork, saddle is arranged on vehicle frame, and both sides, vehicle frame rear are provided with trailing wheel.The vehicle frame of telling comprises connection pipe, saddle pillar and rear vehicle frame, between the rearward end of connection pipe and the leading section of saddle pillar for being flexibly connected, between saddle pillar rearward end and rear vehicle frame leading section for being flexibly connected; Saddle is fixedly connected with saddle pillar, and saddle rear is provided with backrest and is fixedly connected with saddle pillar, and saddle and backrest are all positioned at rear vehicle frame top.

Adopt the folding tricycle of such scheme, can by between the rearward end of connection pipe and the leading section of saddle pillar be flexibly connected and saddle pillar rearward end and rear vehicle frame leading section between be flexibly connected, three-wheel vehicle is folded.Structure for tricycle after folding is compacter, takes up room less.

As preferred version, connection pipe is downward-sloping, and the angle between connection pipe and front fork is acute angle; Saddle pillar cross-sectional plane is that U-shaped groove and side are quadrilateral structure, and saddle pillar bottom surface is horizontally disposed with.

Adopt after such structure, can make between connection pipe and saddle pillar angle less, and then car body is at utmost folded.

As preferred version, saddle pillar front end is provided with front latch hook, between front latch hook and saddle pillar, for being flexibly connected, is provided with the front pinning adapting with front latch hook on connection pipe; On rear vehicle frame, be provided with rear latch hook, between rear latch hook and rear vehicle frame, for being flexibly connected, saddle pillar rear end is provided with the rear pinning adapting with rear latch hook.

Adopt after such structure, can guarantee the stability of this topic, and then guarantee children's safety.

As preferred version, backrest rear is fixedly connected with long handle handrail.

Adopt after such structure, the head of a family can control travel direction and the speed of car by long handle handrail, avoid children to cause danger.
