Abstract
The utility model relates to an electric bicycle which aims to solve problems of an existing electric bicycle, and provides an electric bicycle with double back wheels. The electric bicycle with the double back wheels comprises two back wheels arranged side by side. The distance between the two back wheels is 15-30cm. Three supporting points exist between two back wheels and a front wheel and the ground, and therefore even if no external force is exerted, the double back wheels can still keep an erect state, and the phenomenon that the electric bicycle falls over to one side cannot occur. When a user drives the electric bicycle with the double back wheels, what is needed is to control the direction, and the user is needless to take effort to keep balance of a vehicle body. The distance between the two back wheels is 15-30cm and is basically the same as the width of the vehicle body above the back wheels, so the whole occupied space of the electric bicycle cannot increase because of the additional arrangement of a back wheel.
Description
Technical field
The utility model relates to a kind of Electrical Bicycle, relates in particular to a kind of double rear wheel electric bicycle.
Background technology
Electrical Bicycle, refer to storage battery as auxiliary energy on the basis of ordinary bicycle, the Personal Transporter of the electromechanical integration of the control member such as motor, controller, storage battery, handle brake lever and display instrument system has been installed.The maximum speed of electrician's bicycle is 20km/h, and its speed is far above bicycle.All only have a wheel before and after the Electrical Bicycle, therefore in the process of moving, not only need to control direction and also need to keep the car body balance, otherwise the phenomenon of will turning on one's side.
Summary of the invention
The problems referred to above that exist in order to solve existing Electrical Bicycle, the utility model provides a kind of double rear wheel electric bicycle.
The technical solution of the utility model:
A kind of double rear wheel electric bicycle, its special feature are, comprise two rear wheels that are arranged side by side, and the distance between two rear wheels is 15-30cm.Have three strong points between two rear wheels and the front vehicle wheel and between the ground, therefore, double rear wheel electric bicycle can keep upright state under the External Force Acting, can not occur to roll the phenomenon of falling to one.The user only need control direction and need not to take efforts maintenance car body balance when driving double rear wheel electric bicycle.Distance between two rear wheels is 15-30cm, and is basic identical with the width of the car body of rear wheel top, and the space that the integral body of Electrical Bicycle is taken becomes large.
In order to reduce Electrical Bicycle integral body and to take up room under the stable prerequisite of car body keeping, above-mentioned double rear wheel electric bicycle, preferred, the distance between two rear wheels is 20-25cm.
The beneficial effects of the utility model:
Adopt the design of two rear wheels, increased the stability of equilibrium of car body, reduced the probability that rollover occurs in the process of moving.Adopt specific distance between two rear wheels, under the prerequisite that keeps the car body balance and stability, can obviously not increase its floor area.Compare with existing Electrical Bicycle, double rear wheel electric bicycle of the present utility model, simple in structure, safety performance is high.
Description of drawings
Fig. 1 is the structural representation of double rear wheel electric bicycle;
Among the figure, 1. car body, 2. rear wheel.
The specific embodiment
Further specify below in conjunction with accompanying drawing.
Double rear wheel electric bicycle of the present utility model comprises car body 1 and two rear wheels 2.Its car body 1 part is identical with the structure of existing Electrical Bicycle.Basis at original Electrical Bicycle, a rear wheel 2 increases a rear wheel 2; Two rear wheels 2 are arranged side by side, and connect by wheel shaft.Distance between two rear wheels 2 is 20-25cm, so that the overall width of double rear wheel electric bicycle is not more than the overall width of existing Electrical Bicycle.
Claims (1)
