Abstract

The utility model discloses a pedal-type folding tricycle which comprises a front driving steering system, wherein the front driving steering system comprises a front wheel, a front fork, pedals, steering handles and the like; the front driving steering system is connected with a saddle and rear wheels behind by a frame and folding parts. The pedal-type folding tricycle is characterized in that the limitation that a common hand-operated tricycle needs to be operated when both upper limbs are sane is broken through; the pedal-type driving front wheel is adopted, so that the direction is controlled by the upper limbs and when a user operates the tricycle by an unaffected extremity, an affected extremity also can be exercised; due to the design of moving handrails, the pedal-type folding tricycle is more convenient to use; due to adoption of the folding frame, a storage space is saved and the pedal-type folding tricycle is convenient to transport; due to consideration of the problems that certain users have a poor lower limb function and needs to exercise passively and a user is tired when riding for a long distance, two rear wheels can be further designed into an electric driving wheel and a traveling wheel. Due to the advantages of the pedal-type folding tricycle, it is believed that the life of more aged people and physical handicapped people can be greatly improved.

Description

A kind of foot-operated folding tricycle

Affiliated technical field:

The utility model relates to a kind of vehicle, particularly a kind of foot-operated folding tricycle.

Background technology:

Manual tricycle has employing back-wheel drive, also there is f-w-d, with regard to f-w-d, have to adopt chain drum is set on headstock, hand stirs crank and drives chain drum, by chain drive front-wheel, also have lever and connecting rod are set on headstock, hand is pulled lever, lever drives the crank at front axle two ends to drive front-wheel by connecting rod, but these two kinds of three-wheel vehicles all must two upper limbs all sound people could use, while using in addition, the function of lower limb is also not used, someone has developed a kind of tricycle for old people for this reason, adopt foot-operated driving front-wheel, but this three-wheel vehicle general structure is all fairly simple, car load is integrated vehicle frame, can not fold, large and inconvenience transportation takes up room, vehicle seat is also smaller, stretcher is also the stretcher of Regular Bicycle, healthy people can use, but man at an advanced age and lower limb function chump are with regard to bad use, pin is easy to slide from stretcher, handrail and safety strap are not protected in vehicle seat both sides yet in addition, the old,weak,sick and disabled person can not use at all.

Summary of the invention:

For overcoming the above problems, the technical solution adopted in the utility model is: comprise front-wheel, front axle, crank, stretcher, front fork, steering handle, main car frame, folded piece, bogie side frame, handrail, trailing wheel and vehicle seat, it is characterized in that front-wheel, front axle, front fork, crank, stretcher, steering handle connects to form forerunner and steering swivel system successively, the rotating main car frame front end that is connected in of this forerunner and steering swivel system, main car frame is connected with side frames by folded piece, vehicle seat both sides are connected in side frames, two trailing wheels are individually fixed on the frame of the left and right sides, in order to prevent lower limb function, too poor user's pin is stepped on incessantly stretcher, the danger that easily landing causes, described stretcher is all or part of sole type, this stretcher is all or part of around a protrusion upwards, there is the foot of putting of depression at heel place, side is provided with the foot-binding belt of sticking belt or frenulum and so on, described handrail is movable hand rail, when user gets on or off the bus, handrail can be packed up, on described vehicle seat both sides or backrest, be also provided with safety strap, described vehicle seat can fold, and centre is provided with a core, is provided with bedpan below, between described front axle and front-wheel, be also provided with flywheel and flywheel lock, release flywheel lock, front-wheel can slide forward in the situation that front axle is motionless, during use, working as three-wheel vehicle has certain inertia or has outer trying hard to recommend, user's lower limb just can intermittently be had a rest, locking flywheel lock, the wheel function of flywheel is ineffective, front-wheel and front axle run-in synchronism, the problem of being short of physical strength when considering that some user's limb function is too poor and needing passive exercise and user to go on a journey at a distance, the utility model is further that two described trailing wheels can be designed to a powered wheel and a loose wheel, and this powered wheel is controlled by the controller being arranged on steering handle.

Actual gain:

1; Solved the problem that general foot tricycle can not be folding.

2; Solved man at an advanced age and disabled people scholar while using pin step on incessantly stretcher, the easily unsve problem of landing.

3; Solved the too poor problem that can not go on a journey at a distance of some user's muscle power.

Accompanying drawing explanation:

Fig. 1 is side schematic view

Fig. 2 is foldable structure schematic diagram

In figure: 1, front-wheel; 2, front axle; 3, crank; 4, stretcher; 5, front fork; 6, steering handle; 7, main car frame; 8, folded piece; 9, handrail; 10, bogie side frame; 11, trailing wheel; 12, vehicle seat.

The specific embodiment:

Below in conjunction with accompanying drawing, the utility model embodiment is illustrated, in the drawings, front-wheel 1, front axle 2, crank 3, stretcher 4, front fork 5 and steering handle 6 connect to form forerunner's steering swivel system successively, the rotating front end that is connected in main car frame 7 of this forerunner's steering swivel system, main car frame 7 is hinged by folded piece 8 and bogie side frame 10, handrail 9 is articulated with bogie side frame 10 backrest places, rear end, vehicle seat 12 both sides are fixed on bogie side frame 10, two trailing wheels 11 are individually fixed in side frames 10 outsides, the utility model is further also provided with flywheel and flywheel lock between front-wheel 1 and front axle 2, release flywheel lock, front-wheel can slide forward in the situation that front axle is motionless, during use, working as three-wheel vehicle has certain inertia or has outer trying hard to recommend, user's lower limb just can intermittently be had a rest, locking flywheel lock, the wheel function of flywheel is ineffective, front-wheel and front axle run-in synchronism, the problem of being short of physical strength when considering that some user's limb function is too poor and needing passive exercise and user to go on a journey at a distance, the utility model is further that two described trailing wheels can be designed to a powered wheel and a loose wheel, and this powered wheel is controlled by the controller being arranged on steering handle.
