Description

Vehicle charging system and vehicle including the same

Technical Field

The invention relates to a vehicle charging system and a vehicle comprising the vehicle charging system.

Background technique

With the rise of environmental awareness and the rapid consumption of oil, energy crisis has been brought about. Therefore, electric vehicles are developing rapidly nowadays, which use electricity instead of gasoline as the main power source of vehicles. However, ordinary electric vehicles need to rely on external charging methods to input power to charge the battery, so they need to go to the charging station to charge. If the power is exhausted before reaching the charging station, the vehicle will be unable to drive.

In addition, when a car is driving, the airflow will be separated after hitting the car. Part of the airflow will flow along the roof, and part of the airflow will flow along the body. The airflow flowing along the roof and the airflow flowing along the bottom of the car will form a negative pressure area and vortex behind the rear of the car, resulting in an increase in the overall air resistance of the vehicle, causing power consumption of the electric vehicle.

Detailed ways

The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention. The "one" or "at least one" preceding the nouns mentioned in the text does not limit the quantity, and can also be "plural" according to needs. This change in quantity is also within the scope of protection, which should be explained first.

Please refer to Figures 1 to 6, which show a preferred embodiment of the present invention. The vehicle charging system 1 of the present invention is provided on a vehicle body 300. The vehicle body 300 includes a rear end 301 and a chassis 303. The rear end 301 includes a rear end 302. The vehicle charging system 1 includes a wind guide channel 10 and a wind power generation device 20.

The wind guide channel 10 includes an air inlet 11 and an air outlet 12, the air inlet 11 is provided on the chassis 303, and the air outlet 12 is provided on the rear end 302 of the rear end 301 of the vehicle; the wind power generation device 20 includes a fan blade unit 21 and a power generation unit 22, the power generation unit 22 is connected to the fan blade unit 21, the fan blade unit 21 is provided on the wind guide channel 10, and the power generation unit 22 generates electricity by the rotation of the fan blade unit 21. In this embodiment, the power generation unit 22 is provided on the vehicle body 300. The fan blade unit 21 can be a turbo fan or a cross flow fan. In this embodiment, the air inlet 11 is provided on the chassis 303 near the rear end 301 of the vehicle.

Thus, when the vehicle body 300 moves forward, an external airflow is introduced into the wind guide channel 10 so that the wind power generation device 20 generates electricity by wind power; and the negative pressure generated at the rear end 301 of the vehicle body 300 can be reduced. Further explanation: during the driving of the vehicle 300, the external airflow will reversely enter the lower part of the chassis 303 of the vehicle 300. The external airflow is introduced into the air guide channel 10 through the air inlet 11, thereby reducing the airflow volume under the chassis 303 of the vehicle 300 and providing the vehicle 300 with downward pressure to increase the grip of the vehicle 300. The external airflow is then discharged from the air outlet 12 to the negative pressure area behind the rear end 301 of the vehicle, and is able to disperse the vortex formed at the rear end 301 of the vehicle 300 to reduce the wind resistance generated during the driving of the vehicle 300. At the same time, the external airflow introduced into the air guide channel 10 drives the fan blade unit 21 to rotate, so that the power generation unit 22 generates electricity. Furthermore, the air inlet 11 is arranged on the chassis 303 to better maintain the original structure of the vehicle 300.

Preferably, the vehicle body 300 defines a first direction L1 , the first direction L1 is opposite to the forward direction of the vehicle body 300 , and the air outlet 12 is open toward the first direction L1 .

The vehicle body 300 defines a center line, which is parallel to the first direction L1 and passes through the air inlet 11 .

The air outlet 12 is higher than the air inlet 11. The air guide channel 10 further includes a rear guide section 13, which is located between the fan blade unit 21 and the air outlet 12. The rear guide section 13 extends obliquely from the fan blade unit 21 to the air outlet 12 away from the chassis 303. The air inlet 11 can be provided on the bumper or tailgate of the rear end 301 of the vehicle. Therefore, the external airflow is discharged obliquely from the air outlet 12 to facilitate the dispersion of the vortex behind the rear end 301 of the vehicle.

The air inlet 11 is provided with a guide unit 30, which extends obliquely toward the bottom of the vehicle body 300 to protrude from the chassis 303. In this embodiment, the guide unit 30 is a guide plate, and may also be a guide pipe or other guide elements. This facilitates the introduction of a large amount of external airflow below the chassis 303 of the vehicle body 300 to the air guide channel 10. In other embodiments, the guide plate may swing relative to the air inlet to change the amount of airflow introduced.

The fan blade unit 21 is at least partially located outside the air guide channel 10 , so that the external airflow can smoothly drive the fan blade unit 21 to rotate.

The wind power generation device 20 further includes a transformer 40, which is electrically connected to the power generation unit 22 and a power storage unit 50. The power generation unit 22 can supply power to the power storage unit 50 through the transformer 40. In this embodiment, the vehicle body 300 is an electric vehicle, and the power storage unit 50 can supply energy to the electric vehicle motor. The power storage unit 50 is a battery. The power storage unit 50 is arranged on the vehicle body 300.

The wind power generation device 20 further includes at least one inertia wheel 23, which is connected to the fan blade unit 21 for rotation. In the present embodiment, the wind power generation device 20 includes a plurality of inertia wheels 23, which are arranged on two opposite sides of the fan blade unit 21 and outside the wind guide channel 10. Accordingly, when the fan blade unit 21 is driven by wind to rotate, each of the inertia wheels 23 will rotate together, so when the vehicle body 300 moves forward or/and stops after driving, each of the inertia wheels 23 can be kept rotating forward by inertia, so that the fan blade unit 21 can continue to rotate and provide continuous charging, thereby increasing the charging time.

The wind power generation device 20 further includes a first wheel body 24 and a transmission belt 25. The first wheel body 24 is connected to the fan blade unit 21 in a rotational manner. The power generation unit 22 includes a second wheel body 26. The transmission belt 25 is wound around the first wheel body 24 and the second wheel body 26. The power generation unit 22 generates electricity through the rotation of the second wheel body 26. The second wheel body 26 moves with a rotating shaft 27 of the power generation unit 22. The first wheel body 24 drives the second wheel body 26 and the rotating shaft 27 to rotate through the transmission belt 25 to generate electricity.

The fan blade unit 21 includes a drive shaft 211 and a fan blade body 212, and the drive shaft 211 rotatably passes through the fan blade body 212, the plurality of inertia wheels 23 and the first wheel body 24; the first wheel body 24 is located between one of the inertia wheels 23 and the fan blade body 212, so that the plurality of inertia wheels 23 can stably drive the first wheel body 24 and the fan blade body 212 to rotate during inertial rotation, and the center of gravity of the wind power generation device 20 is stable; the wind power generation device 20 further includes a plurality of support seats 28, and the plurality of support seats 28 are provided on the vehicle body 300, and the drive shaft 211 is rotatably provided and passed through the plurality of support seats 28.

The vehicle charging system 1 further includes a cover body 31, which is swingably disposed on the air outlet 12, and the cover body 31 can swing between a covering position and an open position; when the cover body 31 is in the covering position, the cover body 31 covers the air outlet 12; when the cover body 31 is in the open position, the cover body 31 opens the air outlet 12; in this embodiment, the cover body 31 is pivotally disposed on the vehicle body 300. Preferably, an elastic member 32 is further included, and the elastic member 32 is connected between the cover body 31 and the vehicle body 300. The elastic member 32 allows the cover body 31 to elastically cover the air outlet 12 in a normal state. The elastic member 32 is a torsion spring, and the torsion spring is arranged on the cover body 31. An elastic arm 321 of the elastic member 32 is elastically against the vehicle body 300, and an elastic arm 322 of the elastic member 32 is connected to the cover body 31; the cover body 31 keeps covering the air outlet 12 and is not easy to open arbitrarily. It needs to be subjected to a large force (such as the airflow discharged from the air outlet 12) to push it open to open the air outlet 12, so as to prevent external airflow or external impurities from entering the air guide channel 10 from the air outlet 12.

The air inlet 11 is covered with a first mesh cover 60, and the air outlet 12 is covered with a second mesh cover 70. The first mesh cover 60 and the second mesh cover 70 can be used to block external impurities.

The power generation unit 22 may be disposed in the rear compartment of the vehicle body 300 .
