Abstract
An electric hub-driven double-seat four-wheeled minicar is provided with two seats (a left one and a right one) with a small volume. An electric motor arranged in the wheel hub provides power for a battery arranged on the car, and the power supply controls the car speed by an electric speed controller. The utility model is suitable for short-distance application such as on/off duty and shopping in city.
Description
Affiliated technical field
The utility model relates to a kind of electronlmobil that is used as power with storage battery, mainly is a kind of cell type electrocar of miniature vehicle body.
Background technology
At present, various cell type electronlmobils all are that the driving engine on the automobile, fuel tank are replaced with electrical motor and battery, are provided power to drive and are carried out speed governing by speed governing system by battery.Because current battery unit volume capacity is less, the flying power of electronlmobil is very limited, makes popularizing and development of electronlmobil, is very limited.Practical electronlmobil is also seldom arranged so far on the market.
Summary of the invention
Because the restriction of battery technology, it is very difficult to develop large-scale, heavily loaded, long-range electronlmobil, and the electrocar that develops miniature, underloading, short distance is feasible, and it can be given full play to, and the battery-driven car expense is low, pollution-free, noise is low, control is convenient, the characteristics of ride comfort.Under the condition of existing battery technology, the utilization ratio that how to improve battery is to make the key of electrocar.
The technical scheme that the utility model adopted is: adopt following three methods to improve the utilization ratio of electrocar battery simultaneously.1, reduces the weight and the resistance of car with little vehicle body, the battery box of two seats and anterior packed battery side by side about only establishing in the car.2, replace common wheel hub with electric wheel hub, the direct drive tire is saved the intermediate drive link, and electric wheel hub can be used on four wheels, before also can only being used on the two-wheeled of on the two-wheeled or back.3, in the electrical control, battery is controlled the rotating speed of electric wheel hub (wheel) by the chopper-type electronic controller.
Use the electrocar of said method, can reach practical purpose.40～50 kilometers of maximum speed per hours, with 48 volts of 100AH batteries, once charging can be travelled 80～100 kilometers.This car only limits a people or two people to take, and is applicable to short distances uses such as the city is on and off duty, shopping.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the profile scheme drawing of car.
Fig. 2 is an electrical schematic diagram of the present utility model.
Among Fig. 1,1, vehicle body, 2, battery box, 3, front-wheel, 4, trailing wheel, 5, car door.
Among Fig. 2, battery is powered to two (or four) electric wheel hubs by controller, and charger uses 220 volts of alternating current to charge to battery after conversion.
The specific embodiment
In Fig. 1, about 2 meters of the length of vehicle body (1), wide about 1.3 meters, high about 1.3 meters, the first half of outer appearance general car, two seats are located at the car rear portion abreast, anterior battery box (2) for the discharge pond, the door (5) of driving in the both sides, seat, body contour adopts streamline contour.Front-wheel (3) and trailing wheel (4) adopt the tire of 0.4～0.5 meter of external diameter, and two trailing wheels (4) wheel hub direct current drive wheel hub, the power of each electric wheel hub be at 800～1000 watts, 48 volts of rated voltages, 600～700 rev/mins of rated speed of rotation.
In Fig. 2, battery adopts efficient lead-acid sealed battery, 48 volts of total voltages, capacity 100AH, available four 12 volts of 100AH batteries series connection.Also can adopt other high-capacity battery.Controller adopts the chopper-type dc controller, and the rotating speed size of the output voltage control direct current drive wheel hub of controller is with the control speed of a motor vehicle.Car is provided with special charger, can in time charge to battery.
Others such as chassis, turn to, brake, keep away shake, damping, illumination etc. can adopt the general car technology.Because vehicle is less, the speed of a motor vehicle is lower, and suitable simplification can be carried out in these aspects, with cost-cutting.
Claims (3)
1. an electrocar of being made up of wheel, vehicle body, battery, motor, controller etc. is characterized in that: two seats about having only in the vehicle body.
2. according to the described electrocar of claim 1, it is characterized in that: the wheel hub of front or rear wheel is the electric wheel hub that motor is housed.
3. according to the described electrocar of claim 1, it is characterized in that: the speed of electric wheel hub is passed through the chopper-type electronic controller controls by battery.
