Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicles, and in particular to an electric vehicle which generates electricity using wind energy. Background Art

[0002] Electric vehicles in the prior art are usually equipped with a number of batteries. The larger the battery capacity and the greater the number of batteries, the longer the endurance of the electric vehicle. However, the batteries are still charged in a single way using AC power. When the user forgets to charge, the electric vehicle cannot be used. When the user is traveling long distances, if there is a power outage, it is inconvenient to use.

[0003] At present, there are some electric vehicles with wind power generation devices installed on them to charge the batteries of the electric vehicles when the vehicles are moving forward. For example, the document with publication number CN201457670U discloses a power generation electric vehicle, on which the wind turbine installed can convert wind energy into electrical energy by relying on natural wind or wind generated by the electric vehicle, and supply the electrical energy to a power supply device installed on the electric vehicle to enable the electric vehicle to travel. The electric vehicle can travel continuously without frequent charging, is easy to use, and saves energy. However, the structural design is unreasonable, the wind energy utilization efficiency is low, and the wind blades are exposed, which are easy to be damaged and may cause harm to people, resulting in poor safety. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide an electric vehicle which uses wind energy to generate electricity.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is an electric vehicle that uses wind energy to generate electricity, comprising:

[0006] Electric vehicle body;

[0007] A wind power generation module, which is arranged in the front housing of the electric vehicle body and is used to generate electricity using wind energy generated during the forward movement of the electric vehicle body;

[0008] A storage module, which is arranged in the electric vehicle body and is used to store electric energy;

The wind collecting hood is fixedly connected to the front side shell of the electric vehicle body, and the wind collecting hood is opened at the front and rear to form an air duct. The rotating shaft of the wind impeller is coaxial with the wind collecting hood, and the rotating shaft of the wind impeller is connected to the rotating shaft of the generator, so as to realize the conversion of mechanical energy into electrical energy. The generator is electrically connected to the storage module through a rectifier transformer and a circuit switching controller;

[0011] The storage module includes a battery pack 1, a battery pack 2, and a battery pack 3. The storage module is electrically connected to a motor on an electric vehicle body through a circuit switching controller, thereby providing power for the electric vehicle body. The charging port on the electric vehicle body is electrically connected to the storage module through the circuit switching controller.

[0012] The protective device comprises a protective net fixedly arranged at the front end of the wind collecting cover.

[0013] Furthermore, the diameter of the wind collecting hood gradually decreases from the front end to the rear end, forming a bell-mouth shape, which is more conducive to wind collection.

[0014] Furthermore, the battery pack 1, the battery pack 2 and the battery pack 3 all work independently, so that at the same time, one of the battery pack 1, the battery pack 2 and the battery pack 3 is in a charging state, one is in a standby state, and the last one is in a use state.

[0015] Furthermore, the protective net is fixedly connected to the wind collecting cover by bolts, so that it can be disassembled, which makes it easy to remove the protective net for inspection and maintenance of the wind power generation module.

[0016] Furthermore, the protective device also includes a dust cover, which is arranged at the front end of the wind collecting hood and located on the outside of the protective net.

[0017] Furthermore, a threaded connection portion that cooperates with each other is provided between the dust cover and the wind collecting cover or the electric vehicle body. The dust cover and the wind collecting cover or the electric vehicle body are connected by threads, which is convenient for disassembly and assembly.

[0018] Furthermore, the shaft of the wind impeller is connected to the shaft of the generator through an acceleration box. The shaft of the wind impeller is connected to the input shaft of the acceleration box, and the shaft of the generator is connected to the output shaft of the acceleration box, so that electricity can be generated even when the vehicle speed is low or the air speed is low.

[0019] Furthermore, the speed-up box adopts a gear speed-up box.

[0020] Furthermore, the protective net is made of a metal net and the surface is coated with anti-rust paint, so that it is not easily damaged and increases the aesthetics.

[0021] The advantages of the present invention compared with the prior art are: the present invention arranges a through hole in the middle of the front shell of the electric vehicle for arranging a wind collecting hood, which not only optimizes the shell structure of the electric vehicle and reduces wind resistance, but also can better concentrate wind energy through the wind collecting hood, which is beneficial to power generation and improves power generation efficiency. The wind impeller is arranged in the wind collecting hood, which is not easy to be damaged and will not cause harm to the human body, with high personal safety and good overall vehicle aesthetics. Three groups of batteries are used, one group is in a charging state, one group is in a standby state, and one group is in use at the same time, thereby ensuring that the storage module is stably and effectively charged and discharged, ensuring the normal use of the electric vehicle, safe and reliable.

[0030] A wind power generation module, which is arranged in the front housing of the electric vehicle body 1 and is used to generate electricity using wind energy generated during the forward movement of the electric vehicle body 1;

[0031] A storage module, which is arranged in the electric vehicle body 1 and is used to store electric energy;

[0032] A protective device, wherein the protective device is used to protect the wind power generation module;

[0033] A through hole is provided in the middle of the front end shell of the electric vehicle body 1, which can effectively reduce wind resistance and facilitate the subsequent arrangement of a wind power generation module. The wind power generation module includes a wind collecting hood 2, a wind impeller 3, and a generator 4. The wind collecting hood 2 is arranged inside the front shell of the electric vehicle body 1 through the through hole, and the front end contour of the wind collecting hood 2 is matched with the front end contour of the through hole. The end shape and size of the wind collecting hood 2 are designed according to the actual shape and size of the front shell of the electric vehicle body 1, so that when installed, the end of the wind collecting hood 2 is flush with the front shell of the electric vehicle body 1, so as to have a better aesthetics. The wind collecting hood 2 and the electric vehicle body 1 is fixedly connected to the front shell of the wind collecting cover 2, and the fixed connection can be fixed by bolts or by snaps, so as to facilitate loading and unloading. The wind collecting cover 2 has front and rear openings to form an air duct. The rotating shaft of the wind impeller 3 is coaxial with the wind collecting cover 2, and the rotating shaft of the wind impeller 3 is connected to the rotating shaft of the generator 4. When the electric vehicle body 1 moves forward, wind passes through the air duct in the wind collecting cover 2, drives the wind impeller 3 to rotate, drives the rotating shaft of the generator 4 to rotate, and the generator 4 works, thereby realizing the conversion of mechanical energy into electrical energy. The generator 4 is electrically connected to the storage module through a rectifier transformer and a circuit switching controller to realize the storage of electrical energy;

[0034] The storage module includes a battery pack 1 5, a battery pack 2 6, and a battery pack 3 7. The storage module is electrically connected to the motor on the electric vehicle body 1 through a circuit switching controller, thereby providing power for the electric vehicle body 1.

The storage module is arranged at a suitable position on the electric vehicle body 1 according to actual needs, such as being arranged on the internal support beam of the footrest part of the electric vehicle body 1, or being arranged on the support beam in the shell below the seat cushion, which is not limited here;

[0035] The protective device includes a protective net 9 fixedly mounted on the front end of the wind collecting hood 2. By setting the protective net 9, which is a mesh net, it can ensure that the wind passes through the protective net 9 smoothly into the wind collecting hood 2, and can effectively prevent foreign objects such as leaves and floating larger particles from entering the wind collecting hood 2 during the forward movement of the electric vehicle body 1, thereby ensuring the normal operation of the wind impeller 3. At the same time, it also prevents foreign objects such as leaves and floating larger particles from entering the wind collecting hood 2 when the electric vehicle body 1 is parked, and prevents people around from manually driving the wind impeller 3 out of curiosity, thereby achieving effective protection for the wind impeller 3.

[0036] In specific application, during the riding of the electric vehicle, wind passes through the air duct in the wind collecting cover 2, drives the wind impeller 3 to rotate, drives the rotating shaft of the generator 4 to rotate, and the generator 4 works, thereby converting mechanical energy into electrical energy, and storing the electrical energy in the storage module through the rectifier transformer and the circuit switching controller. The battery pack 1 5, battery pack 2 6, and battery pack 3 7 in the storage module all work independently, so that the battery pack 1 5, battery pack 2 6, and battery pack 3 7 are in the same state at the same time: one is in a charging state, one is in a standby state, and the last one is in a use state. For example, battery pack 1 5 is in a charging state for charging, battery pack 2 6 is in a standby state, and battery pack 3 7 is in a use state to provide electrical energy for the electric vehicle, thereby ensuring that the storage module is stably and effectively charged and discharged, and ensuring the normal use of the electric vehicle.

[0037] In this embodiment, the diameter of the wind collecting hood 2 gradually decreases from the front end to the rear end, forming a trumpet shape, which is more conducive to wind collection. The rear end of the wind collecting hood 2 is also fixedly connected to the shell of the electric vehicle body 1 by bolts, so that the wind collecting hood 2 is firmly installed.

[0038] In this embodiment, the protective net 9 is fixedly connected to the wind collecting cover 2 by bolts, so that the protective net 9 can be disassembled, which facilitates the removal of the protective net 9 for inspection and maintenance of the wind power generation module.
