Description
Technical field
The utility model relates to technology of transportation vehicle, relates in particular to a kind of lying type precursor two wheel rickshaw.
Background technology
Bicycle and man is still used by the most of residents of China, be mainly used in the instrument of riding instead of walk, taking exercise, especially along with deterioration of world wide environment pollution in recent years and rising violently of international oil price, the bicycle and man of environmental protection and energy saving more and more is subjected to people's high praise.The maximum bicycle and mans that use at present are to be the two-wheeled structure mostly, but the seat of such bicycle and man is less than normal, being clipped in two rides between striding, be unfavorable for that the people's is healthy, main harm has can cause private parts hyperemia, congestion of prostate, cause inflammation, cause hyperplasia of prostate and prostatitis etc.In addition, when the shank of this bicycle scrunched, buttocks did not have acting point, scrunched effort, and center of gravity is very high, and it is stable to be unfavorable for riding etc., and owing to adopt back-wheel drive, the chain gear distance is longer, scrunches effort.
Summary of the invention
The utility model for address the above problem provide a kind of sitting posture comfortable, scrunch laborsaving, underslung lying type precursor two wheel rickshaw.
For reaching above-mentioned purpose, the technical scheme that the utility model adopted is: a kind of lying type precursor two wheel rickshaw, include vehicle frame, lean against formula seat, man power driving mechanism, front-wheel and trailing wheel, it is characterized in that: vehicle frame comprises front vehicle frame, back vehicle frame, the front vehicle frame front end is installed man power driving mechanism, the centre is installed front-wheel, end and back vehicle frame and flexibly connected the revolute pair that formation can swing, on the front vehicle frame between front-wheel and the revolute pair, be connected with handle, front-wheel and man power driving mechanism chain-driving; Be connected with on the back vehicle frame and lean against the formula seat, the rear wheel frame end is equipped with trailing wheel.
Preferably, the utility model also comprises following technical characterictic:
Described front vehicle frame is terminal to be connected by oscillating bearing with the back vehicle frame, and the front vehicle frame end is connected with vertical pivot, and vertical pivot runs through front vehicle frame and axis refers to ground, and vertical pivot respectively cooperates an oscillating bearing in two up and down, and oscillating bearing uses nut to be connected in the head end of back vehicle frame.
Described back vehicle frame comprises seat frame and rear wheel frame, and the seat frame head end is connected with front vehicle frame is terminal, and seat frame is upward to be stretched and connect and lean against the formula seat, and seat frame and rear wheel frame head end are hinged, rear wheel frame end installation trailing wheel.
Be connected with damping spring between described seat frame and the rear wheel frame.
Described front vehicle frame connects man power driving mechanism and partly is upturned.
The utility model employing leans against the formula seat and the human body area of contact is big, lie when riding and scrunch by formula, solved standard bicycle cause because of seat less, being clipped in two rides between striding and causes the problem of private parts hyperemia, improved the traveling comfort of driving, and buttocks has acting point when scrunching, make scrunch stronger; Adopt f-w-d, abandoned the mode of traditional back-wheel drive, shortened the chain gear distance, it is more laborsaving to ride; Front vehicle frame is connected by oscillating bearing with seat frame, has both satisfied turning to requirement flexibly, has improved front-wheel centering effect again; Whole car center of gravity is low, is beneficial to the stability of riding.

The specific embodiment
In order to understand the utility model better, be described further below in conjunction with specific embodiment and accompanying drawing content, but the utility model is not limited to the following examples utility model.Referring to accompanying drawing 1 to 5:
Press a kind of lying type precursor two wheel rickshaw that the utility model is implemented, vehicle frame comprises front vehicle frame 2 and back vehicle frame 6, front vehicle frame 2 is installed man power driving mechanism 1 and front-wheel 3 and handle 4, back vehicle frame 6 is installed backrest type seat and trailing wheel 7, front vehicle frame 2 and back vehicle frame 6 are connected to form revolute pair, thereby realize turning to of car.Specifically be achieved by the following scheme:
In order to strengthen the traveling comfort of driving, back vehicle frame 6 is divided into seat frame 601 and rear wheel frame 603, be connected with damping spring 602 between seat frame 601 and the rear wheel frame 603, seat frame 601 head ends and 2 terminal connections of front vehicle frame, seat frame 601 is upward to be stretched and connects and lean against formula seat 5, seat frame 601 is hinged with rear wheel frame 603 head ends, the rear wheel frame 603 terminal trailing wheels 7 of installing.Leaning against formula seat 5 is by human engineering design-calculated curve shape and glass-felt plastic one-shot forming, lean against the height of bicyclist's buttocks contact site on the formula seat 5 and the height of front-wheel 3 core wheels and remain basically stable, so car load adds underslung many than standard bicycle of center of gravity behind the bicyclist when riding.And owing to lean against formula seat 5 and increase greatly with people's area of contact, will seat when riding be clipped in stride between, improve traveling comfort.In addition, will lean against the top that formula seat 5 is arranged on oscillating bearing 201, after front vehicle frame turns to like this, make rear wheel frame 603 follow front vehicle frame after people's the action of gravity and turn to, improve car to neutrality.Be convenient to have an effect in order to scrunch, and pedal and ground do not interfere, so front vehicle frame 2 front end settings are the shape that is upturned.Front-wheel 3 and trailing wheel 7 are provided with brake gear, and the structure of brake gear is identical with existing bicycle brake device structure, is braked by the damper brake 402 that is arranged on the handle 401.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalence of being done according to this real utility model application claim changes, and still belongs to protection domain of the present utility model.
