Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicles, and in particular to a four-wheel electric vehicle which utilizes wind energy to generate electricity and increase range. Background Art

[0002] Cars are one of the most widely used means of transportation. Cars can be divided into fuel cars and new energy cars. The power of fuel cars and new energy cars comes from engines and batteries respectively. At present, the driving mileage of cars is basically determined by the amount of fuel in the tank or the amount of electricity stored in the battery. During driving, there is no additional energy replenished, so the driving mileage of a single trip cannot be extended, and the overall energy consumption and energy saving are still insufficient. With the increase in environmental awareness, the attention to automobile energy consumption is also getting stronger and stronger. Therefore, there is an urgent need for a car that can have a certain energy-saving effect and can guarantee the driving range.

[0003] As a new energy vehicle, especially a pure electric vehicle, its direct power source is the on-board power DC power supply, which can be a chemical storage battery, namely a lead-zinc battery, a lithium-ion battery, and a power supply device converted from hydrogen energy. However, due to the limitations of the available space and vehicle load of the vehicle, it is impossible for chemical storage batteries to fully meet the requirements of the vehicle's range, so the on-board power supply device needs to be supplemented with electricity after the vehicle has traveled a certain mileage. Installing solar panels can increase the range, but due to the limited area of ​​the vehicle body and the constraints of the weather, the effect is not good. For this reason, the present invention proposes a four-wheel electric vehicle that uses wind power generation to increase the range. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a four-wheel electric vehicle that utilizes wind energy to generate electricity and extend its range, which has a reasonable structural design and is convenient for promotion.

The motor drives the wheels to move through the vehicle control system to convert electrical energy into mechanical energy output. The battery pack stores energy to provide power for the vehicle.

[0007] An air inlet passage is provided at the front end of the vehicle body, and the air inlet passage is connected to the wind power generation system;

[0008] The wind power generation system includes a generator set, a wind power boosting device, a piezoelectric power generation unit, a rectifier unit, a voltage stabilizing unit, a power storage unit and a controller.

The power generation unit includes a generator, a fan impeller connected to the rotor assembly of the generator, and a controller whose input end is electrically connected to the stator assembly of the generator, and the output end of the controller is electrically connected to the power storage unit.

[0009] Preferably, the controller can automatically adjust the power of the generator according to the position and speed of the vehicle to maximize the use of wind energy.

[0010] Preferably, when the vehicle is traveling at a high speed, the efficiency of the wind power generation system is low, and the power of the generator is low; when the vehicle is traveling at a slow speed, the efficiency of the wind power generation system is high, and the power of the generator is high, so as to make full use of wind energy.

[0011] Preferably, the piezoelectric power generation unit is arranged on the generator set, which generates electric energy in the form of alternating current with the help of wind power. The alternating current is converted into direct current by a rectifying unit, and the direct current is filtered and stabilized by a voltage stabilizing unit before being stored in a power storage unit.

[0012] Preferably, the air inlet passage is arranged at the front headlight position of the vehicle body, or at the top or bottom of the vehicle body.

[0013] Preferably, the air inlet passage is arranged at the top or bottom of the vehicle body.

By arranging an air inlet channel on the vehicle body and converting wind energy into electrical energy for storage through a wind power generation system, it can not only reduce battery consumption and increase the cruising range, but also optimize energy utilization efficiency through automatic control, thereby further improving the performance and practicality of the vehicle.

[0027] like Figure 1 As shown, a four-wheel electric vehicle that uses wind energy to generate electricity and extend its range includes a vehicle chassis 101, a motor, a vehicle control system, a battery pack, and a wind energy generation system 200;

[0028] The vehicle chassis 101 is used to support the entire vehicle body 100. Wheels 102 are installed at both sides of the bottom of the vehicle body 100. The motor drives the wheels 102 to move through the vehicle control system, converting electrical energy into mechanical energy output; the battery pack stores energy to provide power for the vehicle;

[0029] An air inlet passage 103 is provided at the front end of the vehicle body 100, and the air inlet passage 103 is connected to the wind power generation system 200; the air inlet passage 103 is provided at the front headlight position of the vehicle body 100, or at the top or bottom of the vehicle body 100. In another embodiment, the air inlet passage 103 is provided at the top or bottom of the vehicle body 100.

[0030] The wind power generation system 200 includes a generator set 201, a wind power booster 202, a piezoelectric power generation unit 203, a rectifier unit 204, a voltage stabilizing unit 205, a power storage unit 206 and a controller 209. The generator set 201 includes at least one group of power generation units, and the power generation unit includes a generator 207, a fan impeller 208 connected to the rotor assembly of the generator 207, and a controller 209 whose input end is electrically connected to the stator assembly of the generator 207, and the output end of the controller 209 is electrically connected to the power storage unit 206.

[0031] The controller 209 can automatically adjust the power of the generator 207 according to the position and speed of the vehicle to maximize the use of wind energy.

[0032] When the vehicle is traveling at a high speed, the efficiency of the wind power generation system 200 is low, and the power of the generator 207 is low; when the vehicle is traveling at a slow speed, the efficiency of the wind power generation system 200 is high, and the power of the generator 207 is high, so as to make full use of wind energy.

[0033] The piezoelectric power generation unit 203 is arranged on the generator set 201 , and generates electric energy in the form of alternating current by means of wind power. The alternating current is converted into direct current by the rectifying unit 204 , and the direct current is filtered and stabilized by the voltage stabilizing unit 205 before being stored in the power storage unit 206 .

[0034] Working principle:

[0035] The wind power generation system is used to convert the wind energy entering the air intake channel during the driving of the car into electrical energy for storage, which is used to increase the cruising range of the electric vehicle; the wind power generation system can convert wind power through two driving methods. One is to use it directly in the generator set to generate electricity through the fan impeller, and the other is to use the wind power booster 202 and the piezoelectric power generation unit 203 to generate alternating current electricity with the help of wind power for wind power conversion.

[0036] The controller can also automatically adjust the power of the generator according to the vehicle's position and speed to maximize the use of wind energy. For example, when the vehicle is driving on a highway, the efficiency of the wind power generation system may be low, and the power of the generator can be reduced to save more battery energy. When driving on urban roads, the efficiency of the wind power generation system may be higher, and the power of the generator can be increased to make full use of wind energy.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
