Abstract

The utility model relates to a front-driving middle-steering folding tricycle, which is provided with one large driving front wheel and two small idle rear wheels; the entire tricycle consists of two frames which move corresponding to each other, and the rear half frame fixes the two rear wheels, and the front half frame fixes the front wheel, and a connection part of the frame is a steering mechanism of the tricycle. The steering mechanism is arranged behind the front wheel and is lower than the height of the front wheel, and the axes of the steering mechanism is arranged below the butt of the human body, and an angle of 80 to 40 degrees is formed between the axis of the steering mechanism and the horizontal direction, and the contact point between the extension line of the axis of the steering mechanism and the ground is arranged behind the grounding point of the front wheel. A saddle of the tricycle is made of flexible textile, and one end of the flexible textile is connected with the frame which is relatively fixed on the rear end of the tricycle, and the other end is fixed on the frame (handle) which is fixedly connected with the front wheel, and the human body can lie or sit on the textile. The direction of the tricycle can be controlled by hand through a handle which is connected with the front wheel frame and also can be changed by the leftward-rightward leaning of the human body.

Description

Turn to folding tricycle among the forerunner

Affiliated technical field

The utility model turns to the three-wheel vehicle that can fold in the middle of relating to a kind of f-w-d, belongs to a kind of vehicle of individual manpower field of traffic, also has recreational functions simultaneously concurrently, and for no arm or arm the disabled's trip being arranged also is a kind of selection.

Background technology

The bicycle that existing market exists mostly is sitting type structure, its seat is a similar leg-of-mutton structure, the people is placed on the total weight of health above the three-legged structure of crotch portion pelvis when riding, like this can to the trigonum of human body particularly perineal position cause extruding, ride for a long time can be to human body healthy unfavorable.Simultaneously present standard bicycle people human body when riding is upright, and the both hands handle is ridden for a long time and can be felt to have a pain in the back locked wrist.Similarly structure and drawback also are present in above the existing three-wheel vehicle simultaneously.And the three-wheel vehicle that exists at present all mostly is loading and Foldable type not, lack can amusement and leisure bicycle.

The recumbent bicycle of having applied for a patent also because a variety of causes too big as taking up an area of, should not fold, complex structure, cost is too high and recreational not high reason can't be implemented, the experience that the utility model draws has in the past been avoided above-mentioned shortcoming, selects emphasis, advantage and merges and form.

Summary of the invention

The utility model provides a kind of new bicycle that can address the above problem.This three-wheel vehicle has a relative less inertia trailing wheel with two of relatively big driving front-wheel to constitute, car load is made of two movable relatively vehicle frames, the latter half vehicle frame is fixed two trailing wheels, and first half is front-wheel fixedly, and the linking of vehicle frame partly is the steering hardware of car load.Steering hardware is lower than the height of front-wheel at the rear of front-wheel, the axle center of steering hardware below the buttocks of human body, axis and horizontal direction be 80 to 40 the degree angles, along axis direction extend to the ground contact point in front-wheel touchdown point back.The vehicle seat of this car is made of soft fabric, and on soft fabric one end connection and the relatively-stationary vehicle frame in car rear end, the other end is fixed on above the vehicle frame of fixing with front-wheel (handlebar), and people's health places on the fabric, can be lie shape or sitting shape.The control of car direction can be finished by the handlebar that hand shift links to each other with front wheel frame, also can change the direction that car travels by people's tilting of health.

Actv. of the present utility model has solved the drawback of existing bicycle, has realized the purpose that real health exercising and suitable long-distance trip drive, and can not produce the discomfort sensation of the health except that fatigue.The function of the vehicle is realized combining with the function that amusement and recreation are taken exercise.Also taken into account simultaneously cripple's demand.

Below in conjunction with drawings and Examples the utility model is further specified.

The specific embodiment

The structure that shows car load among Fig. 2.Wherein 1 trailing wheel, 2 after poppets, 3 after poppets and girder connecting pin, 4 girders, 5 headrests, 22 pull the latter half that tight steel rope constitutes car, and 11 handlebars, 12 front-axle beams, 13 sprocket shaft bowls, 14 sprocket shafts, 15 cranks, 16 foot-operated, 17 chain protective stents, 18 sprocket wheels, 19 front-wheels constitute the first half of car.On 6 nets, 7 axis, 8 axis in bowl, 9 axis steel ball circles, following bowl of 10 axis, the 20 after poppet adapter sleeves, 21 axle bush constitute the centre portion of car, play the first half and the latter half of connection car.Seat net 6 and handlebar 11, girder 4, reach that available spring is connected between the front-axle beam 12, to play the effect of damping.People's weight drops on above the net 6, and buttocks is near axis 7, and both legs are crossed handlebar 11, and front-axle beam 12 is clipped between the both legs.Turn to and to control the handle of handlebar 11 upper ends and the inclination of health is finished by arm, also can directly finish by the extruding seat net 6 that tilts of health.

Folding the finishing of this car can be by removing the fixedly realization of two after poppets 2 and axis 7.Its method is seen Fig. 4 and Fig. 5.When car is folding, two after poppets 2 respectively by among Fig. 4 with fastening semicircle watt A and the B and the axis 7 tight sockets of after poppet 2 one, its, semicircle watt A above the middle after poppet and the cylindrical side of B have screw thread, this screw thread matches with the negative thread of after poppet adapter sleeve, by upwards screwing after poppet adapter sleeve 20 two after poppets 2 closely is connected then.Two point of connection of such two after poppets 2 by constituting with after poppet and girder connecting pin 3 form triangle connection modes with fixed connection points following and that axis 7 constitutes, have so just limited the activity of two after poppets 2.In order to strengthen the bearing capacity of car, below two after poppets 2, increased by two connecting pins, pull tight steel rope 22 and two after poppets are linked to each other once more by two connecting pins.The car carrying time is pulled tight steel rope 22 and is in and tightens strained condition, pulls tight steel rope 22 after car is folding and is in lax flexible state.

The car folding mode is seen Fig. 5 and Fig. 3.Fig. 5 is the folding figure of car latter half.For car load is folding the first step earlier handlebar 11 is separated with front-axle beam 12 place so that, next step is to remove being connected of two after poppets 2 and axis 7, just after poppet adapter sleeve 20 being rotated down the semicircle watt A that makes above the after poppet separates with B, form the state of Fig. 5, mentioning girder 4 then draws close itself and front-axle beam 12, again two after poppets 2 are rotated inwards by top two points with after poppet is connected with girder connecting pin 3 itself and front-wheel 19 are drawn close, last again handlebar 11 and front-wheel 19 close proximity are formed final folding.Final folding back view is seen the folding three-view diagram of Fig. 3.The process of launching is the inverse operation that folds.

For the usefulness that ordinary people's amusement and recreation and traffic are ridden instead of walk, the utility model can select to use handgrip brake and two kinds of brake mode of service brake.For for the handicapped disabled person of upper limbs, can only select the brake mode of service brake, adopt brake flower-drum or other service brake pattern.
