Description
Technical field
The present invention relates to a kind of multipurpose bicycle, is a kind of being convenient for carrying specifically, the Collapsible bicycle that a car is multiplex.
Background technology
We often need a baggage car to be convenient for carrying luggage conventionally when long-term travel, and in general baggage car can fold, but few people make other purposes with it.Perhaps, we more need a bicycle in travelling in fact, conveniently descended aircraft and train, have left after private car the short term travel in business district and scenic spot.But because the weight and volume of bicycle is all larger, except special bicycle pleasure trip on foot, almost nobody does not have possibility constantly in long-term travel, also carrying a heavy bicycle yet, some bicycle also can fold and be lighter, but still the possibility that can conveniently carry well beyond tourist.To the greatest extent possessor attempts to design the bicycle that can be transformed into baggage car, but also all exists many serious defects and lack practical value.
In newer background technology, there is a product that approaches this case, also commercialization most, has numerous producers producing, the domestic folding bicycle with small wheels A-bike that can morely see, it comes from newer patented technology abroad, is known as the lightest, the minimum folding bicycle in the whole world.Because this car has adopted integrated transmission shifting mechanism and scalable vehicle frame technology, folding, contraction is got up smaller and more exquisite, and because of a large amount of aluminum alloy materials that adopt, weight is also low weight.Also have the patent of invention of a domestic mandate also very similar, application number and Granted publication number are respectively 200910103736.0 and CN 101544259B, but in market, also can not see corresponding product.Below deficiency and the defect of conventional art are mainly described around these two newer technology.
For simplified structure and expendable weight as much as possible, the vehicle frame of these two kinds of cars all adopts succinct and stable triangular structure or is A font structure, thereby can after keeping under the prerequisite of small volume and less weight like this, launching, can reach manned firm requirement of riding by vehicle frame.
But because A font structure upper end is too little, cannot pull open needed distance between handlebar and vehicle seat, therefore it has adopted three methods to expand: the 1st, on the top of A word, added a bit of crossbeam, and make the upper end of A a little wide, again not larger the stable of structure that affect.The 2nd, between handlebar and verticle stem of handlebar, also added a bit of crossbeam, handlebar is leant out forward, so just equal handlebar to the segment distance that moved forward.The 3rd, the needle beam adding on A word top below utilize below flexible vehicle frame to add two hinged bars with flexible vehicle frame, when vehicle frame launches and vehicle frame form another one triangle, the special vehicle seat of installing, this is equivalent between vehicle frame and vehicle seat, also add a bit of crossbeam, makes vehicle seat move backward a segment distance.However, handlebar reach, saddle rear-moving, centre are widened, and it is still less than normal that three sections of extended ranges are added up, and this car of riding still has thigh will encounter the sensation of handlebar while turning.And design like this vehicle frame and produced new safety problem.First, the handlebar leaning out forward, particularly new-type straight handle, the heart do not overlap with front-wheel steering center, after move, cause while turning, be not one hold forward, another hold just having turned backward, but two hands are drawn arc somewhere in the place ahead, front-wheel steering center simultaneously.The not all people of this mode can adapt in the short time, it is violent that to ride this car easily swaying, so and standard bicycle, handlebar is just in time contrary to the cart style handlebar operation skill of palintrope, the reach of handlebar turning center, give to ride and be used to standard bicycle, change suddenly the people who rides this car and increased danger.Secondly, the shortcoming that the scalable central frame beam of A font is high still cannot solve, its main car frame that can only stretch, the function main flexible, locking of his handlebar and vehicle seat is can not separate together with flexible, the lock function unit design with main car frame, not the even flexible modes of vehicle frame of independent Telescopic handle, vehicle seat, then there is people to ride over flexible expansion, when this car of middle high high-crowned vehicle frame is ridden in the street, look what monster was blamed, ride also very uncomfortable.Most of women particularly, do not like rear knee leg to get on the bus, while getting off, more need to draw leg before fast speed, be that women gets on or off the bus and all in the place ahead of car, carries out, this phenomenon was embodied in when summer, women wore skirt especially, because now cannot get on the bus from rear at all, this makes this vehicle have obvious sex preference.In addition, women, also comprise many underactions, when individual short the and older male sex faces a danger by bike, sudden stop descendant alter forward, if be now traditional women's bicycle of large camber beam, just can diverge both legs lands, walking vehicle is making oneself to avoid falling down on camber beam, but if 28 inches of man's bicycles of high straight beam are just difficult in the past, the car of this new A font vehicle frame particularly, vehicle frame is above likely also high than vehicle seat, under she or he not car just can only fall down heavyly, but also may press against, hinder crotch, give cyclist particularly women cyclist bring larger danger.
In addition, above-mentioned front a kind of merchandizing A font telescopic folding BMX (Bicycle Motocross), although volume after folding is less, but cannot or be inconvenient to draw row, and no matter be to shoulder, remove, carry on the back, or portable long-distance fulfiling of bicycle, still have an Arabian Nights, road is far without underloading after all.A kind of A font telescopic folding BMX (Bicycle Motocross) then, just on former basis, carry out a little and add improvement, the difficulty that does not solve this vehicle rides, the subject matter such as impracticable, and slightly aobvious loaded down with trivial details again when design variations becomes baggage car, use while putting two ready-made wheels differences, designs again a wheel back of the body after car, not only the ugly weight that also increased more, have the suspicion of drawing a snake and add feet to it, thereby the more difficult people of having is ready merchandizing.
Summary of the invention
For prior art above shortcomings, problem to be solved by this invention is to provide a kind of foldable luggage trolley that launches to form bicycle, both can facilitate tourist to carry, pull heavier luggage travelling, but also can launch when needed to form a light touring bicycle, and the position of this vehicle carriage is lower, convenient for femalely rides and use.Adopt independent foldable chassis, independent scalable handlebar, independent scalable vehicle seat design simultaneously, can allow height, the distance between them etc. separately of handlebar and vehicle seat more reasonable, solution comfortable, the practical problem of riding, more can not produce the danger that while turning, knee touches handlebar, and under these prerequisites, reach equally effect and the object of volume after folding small volume and less weight.
