Description

A kind of collapsible two-seater four-wheel electric motor car
Technical field
The present invention relates to a kind of battery-driven car, relate in particular to a kind of folding four-wheel electric motor car.
Background technology
Along with the development of society and the raising of people's living standard, the popularity rate of battery-driven car increases fast, drives because it need not manpower; Do not want consume fuel again, as long as the adapted rechargeable battery, rechargeable battery utilizes low ebb; Not only economy but also environmental protection; Therefore it is the upgraded product of bicycle, and is popular to people deeply, and it has become the desirable running vehicle of people's short distance trip.Yet the prior electric car mainly contains two and takes turns two types of battery-driven car and three-wheeled electric vehicles, and two take turns battery-driven car mainly is applicable to person between twenty and fifty, and three-wheeled electric vehicle mainly is applicable to the elderly.Though the prior electric car has brought convenience for people's short distance trip; But along with the quickening of urbanization pace of construction in recent years; The building height that the resident lives constantly increases, and parking, charging of battery-driven car is very inconvenient, and this has become the limiting condition that battery-driven car further develops.The prior electric three-wheel develops from manual tricycle and comes, and the elderly uses the old-fashioned formula headstock of hurdling very inconvenient, and their trick does not resemble the youngster flexible, and the elderly gets on or off the bus very inconvenient.Three-wheel vehicle walking simultaneously stable bad if Turning radius is too small, steering angle is excessive, inclined to one side seat centre-of gravity shift etc. all is easy to produce rollover, causes car to turn over the accident of people's wound in the process of walking.Must develop for this reason drive simple, go saferly, be fit to the four-wheel electric motor car product that the old man uses.This type car should satisfy following requirement:
It is light that the weight of car load is wanted, and volume is little, can go upstairs by an elevator, collapsible putting at home; Get on or off the bus and to make things convenient for, obstacle can not be arranged; Two seats are arranged, be fit to two people and take.
For this reason, people are also in continuous exploration, and have obtained certain effect, but can't satisfy people's requirement fully.For example the Liu Guang of Chinese Shandong Province discloses " a kind of small four-wheel battery-driven car " in Chinese patent CN201932295U; It comprises car body; At the car body front end foldable pedal is set, behind the car body seat, boot is installed, the back box lid of reserve is hinged on the casing; Side at car body is installed steering hardware, and it can make the rider fully unfold both legs, and both legs are placed on the optional position of stretcher; Take advantage of seat comfortable, can foldable pedal is folding after getting off, it is little to take up room when parking; The trip shopper can be placed on boot with article, and case cover is opened the increase storage space, can transport large piece article; There is not the obstacle of bearing circle in this invention, and the rocking bar that turns to that is installed in a side of car body through swing is realized turning to, and is simple in structure; Easy to use, the chassis of battery-driven car is lower, is fit to action inconvenient the elderly and disabled person and uses.
This little four-wheel electric motor car can only be realized the collapsible of stretcher part; Can't fold between the front and back wheel, the volume of car body is also too big, and the seat has only one; Only be fit to single trip; Can't satisfy two old men travel requirement simultaneously, nonfloating rail, the old man inconvenience of getting on or off the bus is all arranged about the seat simultaneously.
