The utility model has two driving methods, with convenience, saved power and safety.
Description
Technical field:
The utility model belongs to a kind of running vehicle, relates to a kind of front-wheel that both can semi-lying type drives and advances, and can drive the adjustable semi-lying type bicycle of driving that trailing wheel advances by sitting posture again.
Background technology:
Bicycle is since invention, develop towards comfortable, laborsaving, quick, safe direction always, but today, the development of bicycle still was unsatisfactory, also exist many shortcomings: (1) seat gesture is uncomfortable, and vehicle seat is a triangle, and front end places two femoribus internus, the skin so rub easily in the time of by bike, and just in time push cyclist's perineal position, make the people feel numb on every side for a long time by bike, and be unfavorable for healthy.(2) both shoulders are stressed big, and the locations of structures of vehicle seat and handlebar is impelled cyclist's forward lean, so both shoulders are stressed greatly, the both shoulders of riding for a long time can be felt to ache.(3) speed is slow, and it is vertical that vehicle seat and pedal are bordering on, and this structure is pedaled firmly insufficient, so speed is slow.(4) vehicle seat height, the centre of body weight height is unfavorable for balance, poor safety performance is not suitable for children and old man and uses.
Summary of the invention:
The purpose of driving of the present utility model is adjustable semi-lying type bicycle is to overcome the above-mentioned deficiency of existing ordinary bicycle, improve the structure of bicycle, realize the semi-lying type bicycle sit gesture comfortable, drive laborsaving, driving safety steadily, flexible operation, fireballing characteristics.
The utility model drives adjustable semi-lying type bicycle content Description:
The utility model is made up of handlebar, vehicle frame, vehicle seat, wheel and transmission device.Handlebar (15) adopts the flat handle modeling of ordinary bicycle: vehicle frame (3) adopts low early and high after form, and horizontal coupling hook pipe (17) and standpipe (4) before and after the last pipe (14), chain stay (5) form lune with upright fork (8) and standpipe (4) and be connected; Vehicle seat is made up of seat cushion (12) and backrest (11) two parts, two parts all adopt spring pin (13) to be fixed on the vehicle frame (3), seat cushion (12), backrest (11) and rocking arm (10) be by hinge-coupled, and have two fixed positions, forms semi-lying type posture and sitting posture posture by bike by bike.Wheel adopts small one and large one design, and front-wheel (2) adopts 18 inches tire, and trailing wheel (6) adopts 26 inches tires.Two cover driver trains lay respectively at the front portion of middle part and jaw pipe (17), form by sprocket wheel (21), flywheel (1), chain (23), crank (19), foot-operated (18).The transmission principle of it and ordinary bicycle, outstanding advantage has two kinds of modes of riding, comfortable, laborsaving, safety exactly.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is seat moulding and riser upper structural representation.
Among Fig. 1:
