Description

A kind of Foldable pedal parts of foldable double-seat three-wheeled electric vehicle

Technical field

The present invention relates to a kind of folding electric three-wheel vehicle, relate in particular to the pedal parts of folding electric three-wheel vehicle.

Background technology

Along with increasing of social elderly population, social senilization's problem is more and more outstanding, and old man's year and disabled person's trip problem also is not well solved.Although now for they have developed electro-tricycle or three-wheeled electric tricycle for the disabled, also there is following defective in actual use in existing electro-tricycle:

1. these vehicles all are that manual tricycle develops and to come, and the front vehicle frame of this class electro-tricycle is old-fashioned hurdle-type, and the elderly and the disabled's trick does not resemble the normal youngster flexible, gets on or off the bus very inconvenient.

2. car load does not possess the function of unfolding, park floor area large, for the elderly who lives the cities and towns high-rise building, the storage problem of electro-tricycle is very outstanding, especially the family that does not have the garage, even children give presents to one's elders the old man and buy an electro-tricycle and give them, the old men also dare not want, and are placed on the outside and are afraid of to steal, put too large because of volume again at home, weight cannot be taken upstairs greatly, can not go upstairs by elevator, and carrying is inconvenient.

3. function singleness does not possess and sits the leisure function such as lie, and can only mannedly the walking of existing electro-tricycle when the old man feels fatigue, can not be satisfied old man's seat, the leisure function such as lie.

4. existing Portable electric three-wheel vehicle can only be for single, picks child inadaptable old age and go to school or be with my old man's requirement of going together.

5. the monolateral stability of getting on the bus is bad, is easy to rollover, and safety in utilization is poor.

The defective that exists in order to overcome existing three-wheeled electric vehicle, the applicant has successfully developed a kind of multifunctional foldable two-seater three-wheeled electric vehicle, and it has following features:

1. car load is collapsible, and the thickness after folding is 45 millimeters ~ 50 millimeters, and volume is less, can advance elevator and can enter house, tows conveniently, puts that to account for the tool space at home little;

2. HOP ON–HOP OFF is accessible, can not produce rollover, guarantees to get on the bus and get off safety;

3. have two seats, and the seat of back can receive and can put, can a people ride, also can two people take, adapt to the old requirement of picking that child goes to school or going together with my old man.

4. possess and sit the leisure function of lying, satisfied old man's seat, the leisure requirement of lying.

This three-wheeled electric vehicle is simple in structure, and convenient driving, driving safety are particularly suitable for the old man and use.The Foldable pedal parts are one of critical components of this foldable double-seat three-wheeled electric vehicle.

Summary of the invention:

The Foldable pedal parts that the purpose of this invention is to provide a kind of foldable double-seat three-wheeled electric vehicle, it is the foot piece that people get on or off the bus, also being affects critical component folding between front vehicle frame, rear vehicle frame, the dibit seat component.

The technical scheme that the present invention takes is:

A kind of Foldable pedal parts of foldable double-seat three-wheeled electric vehicle, it is characterized in that: comprise left-hand tread plate, right-hand tread plate, pipe link, front support hole, rear support hole, peg and rear pin, left-hand tread plate is captiveed joint by pipe link with right-hand tread plate and is integral, front end at left-hand tread plate and right-hand tread plate is provided with the front support hole, be provided with the rear support hole in the rear end of left-hand tread plate and right-hand tread plate, the axis in front support hole is parallel with the axis in rear support hole, and rear guide is contained in the rear support hole, and rear pin is horizontally fixed on the lower end of peg.

Such Foldable pedal parts have been arranged, could fold between ability front frame component, rear frame part, the dibit seat component three, it can make the electro-tricycle car load collapsible, and volume after folding is less, can advance elevator and can enter house, and institute takes up space little; All-in-one-piece stretcher is more convenient for taking the people and is got on or off the bus freely, can not produce rollover, guarantees to get on the bus and get off safety; Be provided with two seats, but and the seat folding and unfolding of back, solely the people rides, and also can two people take, and adapts to pick child old age and go to school or be with my old man's requirement of going together.Possess simultaneously and sit the leisure function of lying, satisfied old man's seat, the leisure requirement of lying.
