Description

The luggage bicycle structure

Technical field

The utility model is relevant for a kind of luggage bicycle structure, refers to that especially a kind of a kind of the riding that can carry baggage container, shopping basket use carrier, and a kind of luggage bicycle of folding rapidly.

Background technology

Modern's out on tours or to be in harmony public chance very frequent, and the most normal accessory appliances that uses of durante absentia is baggage car, does not more take up space in order to stress the carrying convenience of going out, but advanced at present baggage car design all is a folding.

For example, the foldable structure improvement of No. 557886 baggage car of TaiWan, China patent is a typical typical example, it consists predominantly of base, folding pull bar and permanent seat are formed, the fixedly carrier of this base and two portable plates are coupling with its axis part contraposition, this two portable plates bottom surface is installed with road wheel, the inboard has been horizontally set with at least one axis part, the position can supply a slide plate setting in fixing carrier bottom surface, and this slide plate can be gone forward in fixing carrier bottom surface, slide in the back, move being positioned at the end fluting of portable plate in order to do the card projection that makes the slide plate both sides, portable plate can movablely be folded, or the card projection is moved in the positioning embeded groove, and reach the location when portable plate launched; Assembly is all collapsible folds by two portable plates of base and folding pull bar etc., in order to do making overall volume obviously to dwindle, meets to have and does not take up space and portably use effect easily to fill part.In addition, also have many other identical this type of improvement design, give unnecessary details no longer one by one in this.

Only, though known general baggage car, shopping cart integral structure experience many improvement in design, but when use is moved, often can only draw walking with pulley, travel rate is very low very loses time, and in the streets another kind of being known as has the collapsible bicycle of taking in function, its structure is often because heavy, and the forfeiture locomotivity, so, still can increase many puzzlements when needs up and down during public transportation.

Summary of the invention

For effectively improving above-mentioned known general baggage car and the existing shortcoming of folding bicycle, the utility model the people study especially with great concentration, and development and Design goes out a kind of have concurrently convenience and practicality and multi-functional innovation structure.

Main purpose of the present utility model is providing a kind of luggage bicycle structure, and it comprises: but the handlebar stem, that can draw commutation has the base plate of travelling wheel, a Combined chair and the transmission group that a rotation direction folds; This handlebar stem, dilatory commutation is articulated in the base plate front end, and the handlebar stem below is provided with preceding travelling wheel; This base plate, on handlebar stem, floor below has back travelling wheel to the upset folding by pivot; This Combined chair, rotation direction fold or launch to stride frame between handlebar stem and base plate and; This transmission group has chain and gear cluster and is equipped on behind the base plate between the travelling wheel and handlebar stem.

Thus, during composition, drive also working power motor-driven bicycle,, when placing handlebar stem the place ahead, then can work as Kickboard Scooter and use if with Combined chair bending collection but can be used as bicycle.And this base plate can further be set as the movable telescopic lengthening, cooperates Combined chair folding or expansion, to put baggage container, shopping basket, uses as baggage car, shopping cart.Also base plate upset folding can be against on the handlebar stem, and present best folding state sample.
