Abstract
The invention belongs to field of vehicles, on one side the stroke greatly that cooperates by triangle frame with vehicle frame is adjusted the bucket type seat and the single-arm suspension cable wire priming hub formula wheel flutter of the band handlebar of position, transmission system, compositions such as Running System.Can select for use the high, normal, basic position that waits to ride, satisfy the requirement of various uses, when riding with low position, empty resistance coefficient is 0.65-0.75, resistance is little, and laborsaving, good stability, physical efficiency performance and personal weight distribution more become rationally, the enjoyment of riding that can obtain to enrich by conversion difference positions.Vehicle frame can be amounted to, structure is trendy, can be used as daily traffic and physical training or amusement and travel car.
Description
The invention belongs to field of vehicles, be suitable for daily riding instead of walk or the traffic of middle and long distance and physical training etc.
Existing bicycle keeps the shape and structure of Britain's design-calculated " Jinyang light " board bicycle in 1907 basically, ditrigon vehicle frame and V shape front and rear suspension, saddle seat, handlebar and foot-operated between also can only realize the adjustment of the simple trace that distance is last.Riding posture is the mono-sitting posture that leans forward, and wind area is big, personal weight distribution is undesirable, and power transmission efficiency is not high, influenced effective performance of muscle power, and air resistance big (coefficient of aerodynamic drag is 0.9), in ride for a long time tired easily, structure is complicated, and pattern is outmoded.Ha Pu (HyPer) has been though the backrest type bicycle that company releases has overcome some shortcomings of old-fashioned car, and it is single also to exist the position of riding, and volume is bigger than normal, and complex structure such as can not amount at problem.
The present invention be directed to the deficiency of above-mentioned existing bicycle and design-calculated a kind of can according to different situations such as road, purposes, the speed of a motor vehicle and require convenient adjust change, seat, handlebar significantly and ride between the relation of angle and position, the high position chair type of low speed is ridden and the low position hypsokinesis backrest type of high speed is ridden in the realization, and can amount to.
Foldable cycles adapted (accompanying drawing is wherein a kind of embodiment) of different rider's position needs is made up of a upright triangular form vehicle frame and transmission system, steering system, Running System, brake system and seat, the preceding inclined tube of spider 1. front end is that 2. the forward mounting of single arm, top are connected with articulated with the back inclined tube, back inclined tube is with two parallel seat slide rails, 3. the bottom is connected at the crossbeam rear portion with lower oblique tube with movable riveting pin, lower oblique tube also is the parallel compositions of two arms, and device hangs drive wheel after transmission system and V shape are arranged, and front end hangs the top with cranking arm of preceding inclined tube and 5. is connected with knot that can be undone by a pull.Front-wheel adopts cable wire priming hub core type to turn to and the braking of hub formula.On the back inclined tube slide rail device have the band handlebar the bucket type seat 4., handlebar is fixed on the seat front upper place or the bottom side can the labour contractor be located to lower swing and on specific angle for the center of circle, and can on the inclined tube slide rail of back, move up and down synchronously or lock with seat, trailing wheel adopts jaw type or the braking of hub formula.When using high position to ride do short range, seat is pulled to the vehicle frame top and locks can be riding.Unclamping the seat tab when using low position to ride as middle-long distance moves to the slide rail bottom with seat and can make the hypsokinesis backrest type and ride.Also can select for a post the meaning position on slide rail rides.Elder generation's folding and unfolding seat is to the bottom when amounting to, and unclamps and the knot that can be undone by a pull of mentioning the crossbeam front end is folded to preceding inclined tube that the rear portion is fixing to get final product again.
The present invention can satisfy the requirement of various uses, when riding with low position, air resistance is little, empty to hinder coefficient between 0.65-0.75, low, the good stability of center of gravity, has good road-holding property, can bring into play physical efficiency to large extent effectively, personal weight distribution is reasonable, in the indefatigability of riding for a long time, by adjusting the enjoyment of riding that different positions can obtain to enrich, structure letter refining, modern design, in light weight, amount to conveniently.
Accompanying drawing such as one of them embodiment of the present invention are among the figure: 1. be preceding inclined tube; 2. be the back inclined tube; 3. be lower oblique tube; 4. for being with the bucket type seat of handlebar; 5. be knot that can be undone by a pull.
