Abstract

The utility model relates to a bicycle, particularly a sitting-sleeping type high speed bicycle. The sitting-sleeping type high speed bicycle is composed of a bicycle frame, a front wheel, a back wheel, an ordinary chain wheel, a variable speed chain wheel, a handle bar, a universal joint, a pinion, etc. Since the structures of a bicycle seat and a bicycle body of an original bicycle are changed, a drive component is added and the centre of gravity is decreased. Therefore, the utility model has the advantages of high bicycle speed, smooth running, safety, comfortableness, etc. Simultaneously, because the bicycle seat can move front and back, the bicycle is suitable for people with different stature to ride.

Description

Sitting-sleeping type high speed bicycle

The utility model relates to a kind of bicycle.

At present, the employed bicycle majority of people is two kinds of ordinary bicycle and variable speed bicycles, the ordinary bicycle speed of a motor vehicle is slower, vehicle frame and seat are higher, get on and off to people and to bring a lot of inconvenience, for derailleur, although the speed of a motor vehicle is fast, but because the center of gravity height also can bring danger to people when running into emergency situation and descending.

The purpose of this utility model is to provide that a kind of center of gravity is low, speed is high, the seat horizontal high-speed bicycle of safety and comfort.

The purpose of this utility model is to realize like this, this bicycle is by vehicle frame, front-wheel, trailing wheel, common chain wheel, the speed change chain wheel, handlebar, universal-joint, the parts such as vehicle seat that have movable backrest constitute, its handlebar links to each other with front fork by a universal-joint, the vehicle frame front end is equipped with the chain wheel that links to each other with pedal, the rear end is equipped with a chain wheel, have a miniature gears on the same axle, the centre is equipped with two speed change chain wheels on the both sides of change-speed box, change-speed box is fixed on the vehicle frame, be connected with a miniature gears on the axle of previous speed change chain wheel, be connected with chain wheel on the axle of back one speed change chain wheel, on vehicle frame, be equipped with the vehicle seat that moves forward and backward that has moving backrest.

The utility model has increased drive disk assembly owing to changed the structure of original bicycle body and vehicle seat, has reduced center of gravity, so have speed of a motor vehicle height, travel steadily, advantage such as safety and comfort, because the seat can move forward and backward, therefore, the people who is fit to different statures drives simultaneously.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is for sitting horizontal high-speed bicycle structure scheme drawing.

Fig. 2 is for sitting horizontal high-speed bicycle running part structural representation.

Below in conjunction with the accompanying drawing detail concrete structure of the present utility model and condition of service are described, this bicycle is by vehicle frame (1), front-wheel (4), trailing wheel (7), common chain wheel (11), (13), (15), speed change chain wheel (9), (10), handlebar (2), universal-joint (3), miniature gears (14), (16) etc. major part is formed, its handlebar (2) links to each other with front fork by a universal-joint (3), the vehicle frame front end is equipped with the chain wheel (13) that links to each other with pedal (8), the rear end is equipped with a chain wheel (11), have a miniature gears (16) on the same axle, the centre is equipped with two speed change chain wheels (9) on the both sides of change-speed box (5), (10), on the axle of last speed change chain wheel (9), be connected with a miniature gears (14), be connected with chain wheel (15) on the axle of back one speed change chain wheel (10), change-speed box (5) is connected on the vehicle frame (1), is equipped with a vehicle seat that moves forward and backward (6) that has a moving backrest on vehicle frame (1).

The utility model is by the chain wheel (13) of three diameter 15cm, (15), (11) and two be 15cm by diameter, 10cm, the speed change chain wheel (9) that three chain wheels of 5cm are formed, (10), two miniature gearss (14) that diameter is 5cm, (16), constitute driving system with a small flywheel (12), when travelling, driving chain wheel (13) by foot-operated pedal (8) rotates, give miniature gears (14) by chain gear, pass to two speed change chain wheels (9) again, (10), drive miniature gears (16) by chain wheel (15), pass to flywheel (12) by chain wheel (11) at last and make bicycle running, on different road surfaces, can regulate the moving velocity of car by change-speed box.

Claims (1)

1, a kind of bicycle, particularly a kind of seat horizontal high-speed bicycle, it is by vehicle frame (1), front-wheel (4), trailing wheel (7), common chain wheel (11), (13), (15), speed change chain wheel (9), (10), major parts such as handlebar (2), universal-joint (3), miniature gears (14), (16) are formed, and it is characterized in that:
