Description
Technical field
The present invention relates to a kind of folded bicycle, especially a kind of multifunction folding trolley.
Background technology
Current social family-sized car is more and more universal, also brings the problem of parking difficulty simultaneously, if go the emporium shopping, usually needs car is stopped to far place, then the walking even the market that takes bus again.So country greatly develops public big public transport, also need walking one segment distance or have only the distance on ground, one or two station to need the situation of moveing backward again but also can occur getting off when taking pubic transport the destination.The employee on business trip is to the other places, take taxi fare with high, the situation of taking transit bus and can occur but frequently moveing backward apart from not far, the increase expense that wastes time influences efficient, residential quarter and factory's campus floor area are increasing now, small vehicles is preferably arranged when these place flows of personnel or shopping, the shortening time raises the efficiency, the common vehicle or the existing vehicle carry upstairs or put all inconveniences of subterranean room, so be badly in need of a kind of vehicle of carrying, folded bicycle or electric motor bicycle with folding, folding fuel vehicle are first-selected, but existing folded bicycle has following problem:
1. stem can only be folding to the side because can't pack up with the relation of front-wheel, and volume after folding is big, carries inconvenience.
2. function singleness can only be carried on the back by portable shoulder after folding, and steamboat is assisted in increasing in addition again of also having.
3. some folded bicycle volume after folding is also smaller, but the wheel footpath is too little, and to bicyclist's technical requirements height, road pavement requires high, and safety is low.
4. the Auxiliary Power Unit setting position is unreasonable, takes up room.
Following patent is the relevant Chinese patent that the applicant retrieves, but they all have various deficiencies.As: the patent No. is 02205062.0 to need in addition additional steamboat to increase equipment, can not the loading walking after folding, and stem folds into front-wheel one side and takes up room.The patent No. is 200620175391.1 to be difficult three case ﹠ wheel types of riding.Application number is 200410102431.5, folding back vehicle frame is the same with common folded bicycle to be marginal another side with vehicle seat standpipe and stem, volume is big, stem folds into front-wheel one side and takes up room in addition, can easily not move after folding, especially can not the loading horizontal positioned, can not use as the rest article of stool one class.Application number is 200610069682.7 difficult three case ﹠ wheel types of riding, and needs the two-stage chain.Application number is that 200710073549.3 trailing wheel is folding to forward position front and back wheel connection lead direction from the back, and volume after folding is big, does not have other functions.The patent No. is to move the formula folded bicycle behind the 03239646.5 saddle standpipe, moves vertical use behind the saddle standpipe and does not have other folding modes, and volume is big.The patent No. is the folded bicycle that can stand and drag after 200420003447.6 foldings, and when three-wheel vehicle is ridden and variant on common overall height degree and the mode, volume after folding is big, does not have other functions.The patent No. is 200420048787.0 1 kinds of auto-folder vehicle frames, and just the front and back vehicle frame is folding to the center on vertical direction, and volume is big, does not have other functions.The patent No. is 200520074587.7 Electrical Bicycle folding stands, and back vehicle frame vertical direction is folding forward, can't draw row, acomia horizontal positioned after volume is folding greatly.The patent No. is 200720181353.1 telescopic box-shaped folded bicycles, though folding back volume is little, but because mechanism problem own and common car have very big difference, the position of riding when riding is firmly unreasonable for riding when riding, and does not highly also meet the human body requirement of riding.
