Description

A kind of multifunctional foldable two-seater three-wheeled electric vehicle

Technical field

The utility model relates to a kind of electro-tricycle, relates in particular to a kind of Foldable 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, and it is very inconvenient to get on or off the bus.

2. car load does not possess the function of unfolding, it is large to park floor area, and 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.

Must develop for this reason drive simple, travel saferly, be fit to the three-wheeled electric vehicle product that the old man uses.This class electro-tricycle should satisfy following requirement:

1. car load is collapsible, and volume is little, can advance elevator upstairs after folding, puts that to account for the tool space at home little;

2. get on or off the bus and to make things convenient for, obstacle can not be arranged, more can not produce rollover, guarantee to get on the bus and get off safety;

3. two seats to be arranged, 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.

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

Through retrieval, the patented technology of domestic relevant folding electric-tricycle has 33, but also there is not a electro-tricycle can satisfy above-mentioned requirements, Jiang Fujun is disclosed folding electric-tricycle in 201210102303.5 at number of patent application, although two seats are also arranged, whole car body can fold front and back, can reduce collection space, but complex structure, folding rear size is also larger, and does not possess the leisure function of lying of sleeping; Simultaneously, the stretcher of this three-wheeled electric vehicle partly vertically folds, and the stretcher area is little, is not easy to the old man and gets on or off the bus, and also has the potential safety hazards such as rollover.
