Abstract

The utility model relates to a double driving electric vehicle, belonging to the technical field of the electric vehicle. The double driving electric vehicle of the utility model comprises a front wheel supporting a faucet, a vehicle frame connected with the faucet and a back wheel provided with a motor, an accumulator installed at the vehicle frame and a controller electrically connecting the back wheel motor and the accumulator. The improvement are that the front wheel is connected with a direct current electric motor arranged at the wheel axle to form an integration, and the accumulator is electrically connected with the front wheel motor through the controller. After being adopted the double driving structural scheme of the utility model, the front wheel and the back wheel are served as the driving wheels, so the dynamic characteristic of the electric vehicle is obviously improved. The double driving electric vehicle is easier and freer than the single driving electric vehicle no matter the slope starting or the cross-country. In the running process, the two motors are mutually served and mutually backup. Even if one motor can not work normally, the double driving electric vehicle can be ridden continuously, so the new requirement of the people to the electric vehicle can be better satisfied.

Description

The dual-driven electric car

Technical field

The utility model relates to a kind of battery-driven car, especially a kind of improvement of driving device for electric vehicle.

Background technology

At present, various Moped Scooters, Electrical Bicycle day by day become the running vehicle of more and more popularizing, and the integrated electric motor wheel on the various model battery-driven cars, speed setting controller, storage battery etc. all become the gauge member or the auxiliary equipment that can buy at any time on the market.Yet, understand according to the applicant, existing Moped Scooter, Electrical Bicycle are all taked the single motor-driven mode of trailing wheel, though drive mechanism is comparatively simple, but there is the not good enough shortcoming of dynamic characteristic, not only off-road capability is poor, the uphill starting difficulty, and motor will make troubles to the car owner when breaking down.

Along with people to the day by day deep familiar with understanding of various battery-driven cars, the existing single battery-driven car that drives has been difficult to satisfy the further demand of people.

Summary of the invention

The technical matters that will solve of the present utility model is: the above shortcoming at existing battery-driven car exists proposes the good dual-driven electric car of a kind of dynamic characteristic, thereby further satisfies the new demand of people to battery-driven car.

In order to solve above technical matters, dual-driven electric car of the present utility model comprises the front-wheel that supports tap, the vehicle frame that connects tap and translator trailing wheel, be placed in the storage battery on the vehicle frame, controller with back turbin generator and storage battery electrical connection, its improvements are: the DC machine at described front-wheel and wheel shaft place connects as one, and described storage battery is electrically connected with preceding turbin generator by controller.

After adopting above-mentioned pair of drive configuration scheme of the present utility model, forward and backward wheel all becomes drive wheel, the dynamic characteristic of battery-driven car be improved significantly, no matter be uphill starting, still cross-country, all much free and relaxed than single battery-driven car that drives.In the process of moving, two motors are not only auxiliary mutually, and backup each other, even a motor breaks down, also can continue to ride, and therefore can satisfy the new demand of people to battery-driven car better.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the structural representation of an embodiment of the utility model.

Fig. 2 is a trailing wheel quick-change structure scheme drawing among Fig. 1 embodiment.

Fig. 3 is the structural representation of stop pin among Fig. 2.

The specific embodiment

Embodiment one

The dual-driven electric bicycle of present embodiment as shown in Figure 1, speed governing brake lever 5 and source switch 6 are housed on the tap, the front-wheel that supports tap is and the motor driving wheel of DC machine 4 one, in the vehicle frame of connection tap and translator trailing wheel two controllers 2 and 3 is housed, and storage battery is housed.Back turbin generator 1 and preceding turbin generator 4 are electrically connected with storage battery by controller 2 and 3 respectively.

Like this, front-wheel and trailing wheel can be simultaneously as drive wheels, therefore Electrical Bicycle startup, upward slope even the off-road capability of present embodiment all obviously improve, and, because two-wheeled is controlled by controller separately respectively, therefore the bigger wheel of resistance will be exported corresponding bigger power, and the performance of compensation is better mutually.

Embodiment two

The dual-driven electric bicycle of present embodiment as shown in Figure 2, its basic structure is identical with embodiment 1.Difference is: vehicle frame only is equipped with a controller 2.Back turbin generator 1 and preceding turbin generator 4 are common by the electrical connection of controller 2 storage batterys.

Like this, front-wheel and trailing wheel have good synchronism, and power output is comparatively average.And circuit structure is comparatively simple and direct, and cost is also relatively economical.

In addition to the implementation, the utility model can also have other embodiments.For example, two drive configurations of above Electrical Bicycle are expanded to electro-tricycle, electric four-wheel vehicle, form the electro-tricycle of two-wheeled or three wheel drive, the electric four-wheel vehicle of four wheel drive, or the like.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.

Claims

1. dual-driven electric car, comprise the front-wheel that supports tap, the vehicle frame that connects tap and translator trailing wheel, be placed in the storage battery on the vehicle frame, controller with back turbin generator and storage battery electrical connection, it is characterized in that: the DC machine at described front-wheel and wheel shaft place connects as one, and described storage battery is electrically connected with preceding turbin generator by controller.
