Description
Technical field
The utility model relates to the foldable luggage trolley that a kind of improved type launches to be formed bicycle.
Background technology
We often need a baggage car to carry luggage usually when long-term travel, 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, leave private car after short term travel in business district and scenic spot.But because the weight and volume of bicycle is all larger, except the pleasure trip on foot of special bicycle, almost nobody does not have possibility in constantly long-term travel way, also carry with a heavy bicycle yet, some bicycle also can fold and lighter, but still well beyond the possibility that tourist can conveniently carry with.
I had once invented " a kind of foldable luggage trolley launching to be formed bicycle " and had applied for Chinese patent for this reason, the patent No. is: ZL201220509258.0, patent application day is: on October 08th, 2012 (conveniently, the utility model adopts the dash number identical or relevant with former " a kind of launch the foldable luggage trolley that can form bicycle " to illustrate as far as possible).Former " a kind of launch the foldable luggage trolley that can form bicycle ", primarily of front-wheel, telescopic folding direction assembly 1, the double leval jib folding stand assembly 3 hinged respectively up and down with front and back assembly of trailing wheel, telescopic folding seat, driven unit 2 and centre is formed.Wherein, double leval jib folding stand assembly 3 comprises: middle folding four-bar linkage 13, respectively with four-bar linkage upper and lower two places hinged formed with front vehicle frame articulated bracket 6 not only be socketed turnably front hinged sleeve pipe 14 and respectively with four-bar linkage upper and lower two places hinged but also form the turnable rear hinged sleeve pipe 15 be socketed with Rear frame articulated bracket 11, when above-mentioned double leval jib folding stand assembly 3 be pulled transversely apart become bicycle rack time, in fact be all unequal non-parallel quadrangle on four limits by front hinged sleeve pipe 14 and rear hinged sleeve pipe 15 former and later two quadrangles hinged formed with the folding four-bar linkage in centre about 13, if the position of all flexible connection axles between the double leval jib that appropriate selection is mutually hinged, described double leval jib folding stand assembly 3 can be allowed to be formed dexterously and its front-wheel be socketed turnably, telescopic folding is direction assembly and trailing wheel, telescopic folding seat, driven unit collapsible is to being parallel during the width of baggage car, and it can form the front-wheel of bicycle when being launched into bicycle rack, telescopic folding is direction assembly, trailing wheel, telescopic folding seat, driven unit forms required angle of inclination with ground separately, a kind of stable trapezoidal state.
Because the footstep mechanism of above-mentioned " a kind of launch the foldable luggage trolley that can form bicycle " and integrated transmission shifting mechanism 9 casing are below telescopic folding seat, cause seeing on the whole, its footstep mechanism is obviously near the rear of whole bicycle.Like this, when bicyclist rides, centre of body weight compares and leans forward, and this posture compares and is suitable for riding fast, and some is as the mode of riding of bicycle racing, if ride slower, this posture will seem that some is awkward and uncomfortable.
Summary of the invention
For prior art above shortcomings, problem to be solved in the utility model is to provide the foldable luggage trolley that a kind of improved type launches to be formed bicycle, break former integrated transmission shifting mechanism 9 casing, allow and the bicycle middle shaft prerequisite as far as possible of footstep mechanism is installed, for this reason, scalable barre, the telescopic folding vehicle frame of bicycle also will make corresponding change, and reach the comfortable and women bicyclist of riding when going slowly and to like being seated the mode of riding of more lying fallow of straight and upright waist.
Due to the wheel diameter of small-wheel bicycle and wheel circumference too small, usually need the converter speed ratio strengthening driver train, namely strengthen foot-operated often revolving and turn around, all numbers of rear wheel, improve the riding speed of BMX (Bicycle Motocross).But no matter be chain sprocket drive or gear transmission, transmitting ratio is excessive, driving wheel diameter all can be caused excessive, namely our wheel disc of bicycle of usually saying or chain drum excessive.So the too small small-wheel bicycle of wheel adopts two-stage chain transmission sometimes.First order transmission, that a hinge wheel transmission is to a minor sprocket, form a transmitting ratio, a hinge wheel be coaxially connected again in transmission to another minor sprocket on this minor sprocket, form another transmitting ratio, the total transmitting ratio of such two-stage transmission is the relation that two sub-transmission ratios are multiplied, and has so both increased total transmitting ratio and has also reduced power wheel diameter dimension.We by chance can utilize this structure, allow power wheel that large steamboat of secondary transmission middle transition is coaxially connected as an action center, change type of drive and transmission position, to reach more comfortable object of riding.
In order to achieve the above object, the utility model have employed following technical scheme:
A kind of improved type launches the foldable luggage trolley that can form bicycle, its running part adopts two-stage type of drive, wherein, and first order Chain conveyer, be one and be connected in bull wheel-driving on axis to a steamboat, second stage transmission is that the bull wheel that is coaxially connected on this steamboat passes downwards again.Above-mentioned two-stage transmission, first order transmission distance is greater than the transmission distance of the second stage, the parts of second stage transmission are all installed together with trailing wheel, allow power wheel that large steamboat of two-stage transmission middle transition is coaxially connected as an action center, make whole first order transmission can along this pivot.This technology based on former " a kind of launch the foldable luggage trolley that can form bicycle " " front-wheel, telescopic folding direction assembly and trailing wheel, telescopic folding seat, driven unit they all can turn to, and they can be locked when all turning 90 degrees to same direction." thus the baggage car state of drawing sidewards could be formed, significantly can swing and create possible space so just to " foldable luggage trolley that a kind of improved type launches to be formed bicycle " whole first order transmission, because during baggage car, trailing wheel rotated ninety degrees is all followed in whole first order transmission and second stage transmission, also can not conflict with the four-bar linkage folded up even if it vertically gets up, thus can by during baggage car close to vertical position, after launching to form bicycle, swing to the position close to level, and then follow trailing wheel and second stage transmission together to returning rotated ninety degrees, the middle axle head of now first order transmission just drops on and to be opened after changing bottom by below the four-bar linkage midway location of evening up, insert the interior locking of locked groove that there is arranged.Thus change the transmission distance of horizontal direction, making axis from being close to rear hinged sleeve pipe 15 side during baggage car, moving to the car load middle part of bicycle state, and it is more comfortable to make to ride.
