Abstract

An auxiliary electrical power apparatus for electrical vehicle is comprised of air intake ducts having a funnel shaped air intake with a forward opening in the front of the vehicle, two air outlets located on opposite sides of the vehicle, a turbine chamber connected to the narrow-mouthed pass of funnel shaped air intake ducts, an electrical generator placed in the vehicle and driven by blades of the turbine. The wind resistance produced by running vehicle makes blades of the turbine rotate, so as to generate auxiliary electrical energy.

Description

TECHNICAL FIELD

The invention relates to an electric energy auxiliary device for an electric vehicle. Background technique

As automotive applications become more widespread, the use of fuel in automotive engines can cause significant environmental pollution. Because the pollution level is very serious, recently, with the help of the development of Kezhi, cars or motorcycles were gradually replaced by electric drives. In general, when the electric car or electric motorcycle is driving, the front end of the car body causes a sensed wind resistance. The wind resistance is a negative impact on the driving and has a certain degree of impact on the loss of electrical energy. .

In view of this, an object of the present invention is to provide an electric energy auxiliary device for an electric vehicle, which applies the resistance of a wind resistance to a charging device and effectively converts the resistance into electrical energy. Allow the rechargeable battery to get extra power while driving. Summary of the Invention

In order to achieve the above object, the present invention proposes an electric energy auxiliary device for an electric vehicle, particularly an auxiliary device that uses an electric wind resistance to convert it into electric energy and feeds it back to a battery while driving. The device includes: An air outlet is set in the front, and an air outlet is provided on the side of the car body. A wind turbine driven generator is connected in series between the two. The generator is located in a wind drum connected to the air pipe inside the car body. A drum is connected forward to the air collecting opening, and the air collecting opening extends inward and is provided with an obstruction, which acts on the blades of the generator.

The air outlet can also be provided on other acceptable windward sides of the vehicle body.

The power generating device can be set in multiple groups. For details of the present invention, please refer to the accompanying drawings as follows. Brief description of the drawings

Figure 1 is a block diagram of the power structure of a general electric vehicle;

FIG. 2 is a block diagram of a structural application of the present invention;

Figure 3 is an embodiment of the present invention;

FIG. 4 is an application diagram for implementing the present invention. Detailed description of the preferred embodiment

First, please refer to FIG. 1. A general electric vehicle includes a rechargeable battery 1 that can be recharged at any time. The battery 1 is charged by an electric charger 11. Generally, the battery 1 can be connected with external electric energy or can be installed in a car body. The power generation engine of the vehicle obtains electric energy to charge the battery 1. The electric power of the battery 1 is mainly the power motor 2 supplying the vehicle body 10, and other device systems such as a lamp system 3, a signal system 4, a horn 5, Air-conditioning system 6 and hydraulic system 7 etc.

Because the car is affected by air resistance while traveling, and this resistance has a negative impact on the car's battery, wasting battery power. Therefore, the present invention particularly utilizes a wind power generating device 80, which is opposite to the air collecting opening 9 and converts kinetic energy via blades 81 to form electric energy, so as to supplementarily charge the battery.

Please refer to FIG. 3 again, the present invention is applied to a vehicle body 10. The front end of the vehicle body 10 is provided with an air collecting opening 9, and the air collecting opening 9 extends into an obstruction opening 90.

As shown in FIG. 4, the obstacle 90 is opposite to a power generating device 80. The power generating device 80 has a wind drum 91. A generator 8 and blades 81 are disposed inside the wind drum 91. The other end is provided with a diversion air duct 92 which is guided to the outside of the vehicle body, and the airflow entering through the air collection opening 9 is discharged through an air outlet 93.

Oncoming wind when the car is running acts on the blade 81 to rotate it, the blade moves to drive the generator 8 to generate electricity, and the electric energy is charged into a battery, so that the battery 1 In this way, the auxiliary charging effect can be obtained while driving.

The air collecting opening 9 is in a state of oblique guiding, so that the oncoming wind force can generate a larger flow velocity, and the obstruction opening 90 acts on the blade 81. With the larger flow velocity, the blade 81 can be made. Generates a faster slew rate, which in turn allows the generator to emit a higher current and provide it to the battery.

The position of the blade 81 is set in such a way that the single blade surface is directly facing the obstruction of the obstruction 90, and the oncoming air flow can be directly applied to the blade surface of the blade 81, and is guided by the air duct 92 and discharged by the air outlet 93. Pressure, the port of the exhaust port 93 faces the rear end of the vehicle body. Because the car body cuts through the surrounding air, it creates a vacuum at the air outlet and causes a negative pressure. The negative pressure is guided to the back of the blade 81 by the air duct 92 to make the blade. 81 A two-way driving effect is obtained, so that the kinetic energy generated when the car is running can make the generator 8 more gainful.

In addition, the charging device of the present invention is provided to face the air outlet. However, the air outlet may be provided on the roof or the side of the vehicle body according to the design form of the vehicle body, or may be provided with multiple groups of charging devices according to the size of the vehicle model. For example, the main charging device can be set on the windward side, while the attached charging device can be set on the car side.

Industrial applicability

The electric energy auxiliary device for electric vehicles proposed by the present invention can apply the resistance of wind resistance to the charging device, and effectively convert the resistance into electric energy. Allow the rechargeable battery to get extra power while driving.

In addition, when the present invention is implemented, in addition to the direct auxiliary charging of the car body battery, it can also directly provide applications such as car body sound and light equipment through other circuit device means.
