Description
Technical field
The utility model relates to a kind of three-wheel folding bicycle that can be exchanged into seat, have ride, occupy stably fixed, conversion, folding convenient, characteristics such as simple in structure belong to the articles for daily use technical field.
Background technology
A kind of and the immediate prior art of the utility model is a kind of two-wheeled folding bicycle, its driver train is identical with traditional bicycle, the manpower that promptly acts on the pedal drives the chain wheel rotation by crank, by chain drive with the drive wheel coaxial flywheel rotation meshing with chain wheel, drive wheel rotates thereupon, is subjected to ground-surface counteraction to order about bicycle and advances.Described two-wheeled folding bicycle also has two kinds of folded forms except the form of riding, a kind of is the transition folded form, can have a rest for the people as stool, and another kind is final folded form, and this form minimum that takes up room adopts when depositing bicycle.Described two-wheeled folding bicycle is not suitable for the elderly and uses, and at first, as two-wheeled cycle, stable inadequately when riding, employed saddle is also safe inadequately, comfortable; Secondly, also stable inadequately as the transition folded form of stool, and, therefore be difficult to satisfy the needs of fully having a rest for parts or saddle that the people is seated.
The utility model content
The purpose of this utility model is a kind of three-wheel folding bicycle that can be converted to seat of design, have three wheels, no matter ride or take a load off one's feet, all more stable, safety, adopt seat to substitute saddle, traveling comfort improves, and still can fold simultaneously, be convenient to deposit, be suitable for the elderly and use.
See Fig. 1, shown in Figure 2, its structure of three-wheel folding bicycle that can be converted into seat of the utility model is, two trailing wheels 1 are installed in sides, vehicle frame 2 back, and two deflecting bars 3 are installed in vehicle frame 2 front sides; Driving front fork 4 one ends are installed on the front wheel spindle and can rotate around front wheel spindle, and driver train is installed in and drives on the front fork 4; Support front fork 5 one ends and also be installed on the front wheel spindle, the other end is connected with chassis 6; Fixed link 7 cross-over connections drive front fork 4 and support front fork 5, with the junction energy dismounting that drives front fork 4, can rotate with the junction of supporting front fork 5; Seat is positioned on the chassis 6, can adjust towards, see Fig. 1, shown in Figure 3, seat is made up of the seat 8 and the chair back 9, the chair back 9 can be around the shaft 10 upsets; Chassis 6 is positioned on the vehicle frame 2, and the two is connected by steering shaft 11.
Its technique effect of the utility model is, by the drive mechanism front-wheel, realizes advancing of this bicycle, make that by handling two deflecting bars 3 vehicle frame 2 and chassis 6 are axle with steering shaft 11, with respect to angle θ of craspedodrome direction swing, realize turning to of this bicycle, see shown in Figure 4.Because this bicycle has three wheels, and press the triangle distribution,, have good stable no matter make it as bicycle or as seat.Adopt seat to substitute existing bicycle saddle, traveling comfort, safety all are improved.Because seat be towards can adjusting, so be in when riding form when this bicycle, seat, is seen shown in Figure 3 with seat backwards during rest forward.The technical measures that realize folded form comprise, see shown in Figure 5, the one, with the chair back 9 discounts on seat 8; The 2nd, fixed link 7 is taken apart in the junction of the two with driving front fork 4, will drive then front fork 4 together with the driver train that is installed on it around front wheel spindle vehicle frame 2 belows of turning back, the other end of fixed link 7 still with support front fork 5 and be connected also sagging naturally.
Description of drawings
Fig. 1 is the overall structure front view of the utility model, and this figure double as is a Figure of abstract.Fig. 2 is the overall structure birds-eye view of the utility model.Fig. 3 be in the utility model seat backwards the state master look scheme drawing.Fig. 4 is that the utility model is realized the steering situation schematic top plan view.Fig. 5 is that the utility model folded form master looks scheme drawing.Fig. 6 is the concrete scheme schematic perspective view of the deflecting bar in the utility model.Fig. 7 is the support front fork in the utility model and the intubate shape and the structural perspective of one end.
The specific embodiment
See Fig. 1, shown in Figure 2, its structure of three-wheel folding bicycle that can be converted into seat of the utility model is, two trailing wheels 1 are installed in sides, vehicle frame 2 back, and two deflecting bars 3 are installed in vehicle frame 2 front sides.There is one section outwardly-bent part 12 deflecting bar 3 belows, to avoid chassis 6 when the handling maneuver to a certain extent, like this obtain less turn radius in convenient the manipulation, see shown in Figure 6.Deflecting bar 3 roots are connected with vehicle frame 2 through articulation joint 13, and when this bicycle was in folded form, deflecting bar 3 was folded to the below, realize folding greatly.Driving front fork 4 one ends are installed on the front wheel spindle and can rotate around front wheel spindle, and driver train is installed in and drives on the front fork 4.Driver train is made of pedal 14, crank 15, chain wheel 16, chain 17 and the flywheel that is installed on the front wheel spindle, and its structure and service condition are same as the prior art.Supporting front fork 5 one ends also is installed on the front wheel spindle, the other end is connected with chassis 6, a kind of concrete connectivity scenario is, supporting the intubate 18 of front fork 5 other ends inserts in two sleeve pipes 19 in 6 middle parts, chassis, see Fig. 2, shown in Figure 7, length in the intubate 18 insertion sleeve pipes 19 can be adjusted and is fixing, and this feature makes this bicycle can be fit to the long people of different legs first and rides, second can reduce space hold by inserting fully in the folded form of this bicycle.Fixed link 7 cross-over connections drive front fork 4 and support front fork 5, with the junction energy dismounting that drives front fork 4, can rotate with the junction of supporting front fork 5; Seat is positioned on the chassis 6, can adjust towards, see Fig. 1, shown in Figure 3, seat is made up of the seat 8 and the chair back 9, the chair back 9 can be around the shaft 10 upsets; Chassis 6 is positioned on the vehicle frame 2, and the two is connected by steering shaft 11.
