Description

A kind of expansion can form the foldable luggage trolley of bicycle
Technical field
The present invention relates to a kind of multipurpose bicycle, specifically one kind is convenient for carrying, a car it is multiplex it is foldable voluntarily Car.
Background technology
We generally generally require a luggage truck in long-distance travel to be convenient for carrying luggage, and in general luggage truck is Can fold, but few people make other purposes with it.We facilitate perhaps with greater need for a bicycle in travelling in fact Descended aircraft and train, leave private car after in business district and the excursion of scenic spot.But due to the weight and body of bicycle , all than larger, except special bicycle is gone hiking, almost nobody also cannot be also carry-on in constantly long-distance travel for product A bicycle for heaviness is carried, some bicycles can also be folded and relatively lighter, but still can be square well beyond traveller Just the possibility carried with.Although someone is attempted to be transformed into the bicycle of luggage truck, also all exist perhaps More serious defect and lack practical value.
In newer background technology, have it is a closest to this case, also commercialization, have numerous producers production product, The folding bicycle with small wheels A-bike that the country more can see, it comes from external newer patented technology, is known as the whole world most gently, most Small folding bicycle.Because this car employs integrated transmission shifting mechanism and scalable vehicle frame technology, fold, shrink Compare compact, and aluminum alloy materials are used because a large amount of, weight is also relatively lighter.The also a domestic patent of invention for authorizing also very class Seemingly, application number and Authorization Notice No. are respectively the B of 200910103736.0 and CN 101544259, but also can not see phase in market The product answered.The deficiency and defect of conventional art are illustrated mainly around this two newer technologies below.
In order to simplify structure as much as possible and mitigate weight, the vehicle frame of both cars is all using succinct and stabilization triangle Structure is A font structures, so that can be on the premise of such small volume and less weight is kept, expansion Rear frame can reach manned The firm requirement ridden.
But because A font structures upper end is too small, it is impossible to pull open distance required between handlebar and vehicle seat, therefore it is used Three methods are extended:1 is to have added a bit of crossbeam on the top of A words, makes the upper end of A a little wide and not larger Influence the stabilization of structure.2 is also to have added a bit of crossbeam between handlebar and verticle stem of handlebar, handlebar is leant out forward, thus Equal to handlebar to the segment distance that moved forward.3 is below using flexible behind the needle beam added on A words top with flexible vehicle frame Vehicle frame has added two hinged bars, and another triangle is formed with vehicle frame when vehicle frame launches, and specially installs vehicle seat, This makes vehicle seat be moved back by a segment distance equivalent to a bit of crossbeam has also been added between vehicle frame and vehicle seat.Even so, handlebar Reach, saddle rear-moving, centre are widened, and three sections of extended ranges add up still less than normal, and the car of riding still has the thigh to touch when turning To the sensation of handlebar.And so design vehicle frame generates new safety problem.First, the handlebar for leaning out forward, particularly newly The straight grip of formula, the heart and front-wheel steer center is misaligned, rear shifting, when causing to turn, be not holding forward, another Holding can just turn backward, but two hands somewhere draw arc simultaneously in front of front-wheel steer center.This side What the not all people of formula can adapt in the short time, it is violent that to ride this car easy to be swaying, thus with it is traditional voluntarily Car, the cart style handlebar operation skill contrast that handlebar moves forward to palintrope, handlebar turning center, tradition has been used to voluntarily to riding Car, changes suddenly and rides the people of this car and increased danger.Secondly, the scalable central frame beam of A fonts shortcoming high still cannot be solved Certainly, it can only stretch main car frame, and his handlebar and main flexible, locking the function of vehicle seat are flexible, the locking with main car frame What function global design can not be separated together, be not the flexible modes of independent Telescopic handle, vehicle seat or even vehicle frame, then someone Flexible expansion is ridden over, when this car of middle high-crowned vehicle frame high is ridden in the street, it appears that strange, ride also very It is uncomfortable.Particularly most of women, do not like rear knee leg and get on the bus, with greater need for draw leg, i.e. women upper and lower before quickly when getting off Car is carried out in front of car, and this phenomenon is especially embodied in summer women when wear skirt, because now at all cannot be from Rear is got on the bus, and this causes that this vehicle has obvious boy preference.In addition, women, also include many underactions, individual short and year Age male bigger than normal is cycled when facing a danger, and the descendant that brings to a halt alters forward, if being now traditional women's bicycle of big camber beam, just Both legs can be diverged to land, walking vehicle across oneself is made from falling down on camber beam, but if being 28 English of straight beam high in the past Very little man's bicycle is difficult to, and the car of particularly this new A font vehicle frames, vehicle frame above is possible to also higher than vehicle seat, she or Car can only just not fall down heavyly under him, but also may press against and hinder crotch, to cyclist particularly women cyclist with Carry out larger danger.
In addition, the A font telescopic folding BMXs of above-mentioned former commercialization, although volume after folding is smaller, But cannot or be inconvenient to draw row, regardless of whether be to shoulder, remove, carrying on the back, or a portable bicycle is long-distance to fulfil, or You Dian old name for the Arabian countries in the Middle Easts Night Tan, road is remote without underloading after all.And latter A font telescopic folding BMXs, a little addition is simply carried out in original basis and is changed Enter, without solve the difficulty that this vehicle is present ride, the subject matter such as impracticable, and design variations are into slightly showing numerous again during luggage truck It is trivial, used when putting ready-made two wheels difference, and design a wheel more and carried on the back after car, it is not only ugly to also add weight Amount, there is the suspicion drawn a snake and add feet to it, thus more difficult someone is ready commercialization.
The content of the invention
For deficiencies of the prior art, problem to be solved by this invention is to provide a kind of expansion and can be formed certainly The foldable luggage trolley of driving, can both facilitate traveller to carry with, and pull heavier luggage travelling, but also can need Shi Zhankai forms a light touring bicycle, and the position of the vehicle carriage is relatively low, convenient for female to ride and use.Adopt simultaneously With single foldable chassis, individually scalable handlebar, individually scalable vehicle seat design, can allow each of handlebar and vehicle seat From height, they the distance between etc. more rationally, solve the problems, such as comfortable, practical, knee when will not more produce turning of riding The danger of handlebar is touched, and under these premises, equally reaches the effect and purpose of volume after folding small volume and less weight.
