The wind power generation device for a vehicle disclosed in Patent Document 1 is installed on the passenger compartment of a freight vehicle. This vehicle has rotor blades that rotate in response to wind while traveling.

International Publication No. 2022/269938

The wind power generation device for a vehicle disclosed in Patent Document 1 is applied to a freight vehicle, as an example, but it is desired to generate wind power also in a motorcycle or a tricycle.

In consideration of the above facts, the present disclosure aims to generate wind power in a motorcycle or a tricycle.

A vehicle according to a first aspect includes a body of a motorcycle or a tricycle, a storage chamber, a wind turbine rotatably housed in the storage chamber about a rotation axis along a height direction of the vehicle body, and An air supply port is located in front of the storage chamber and takes in air into the storage chamber; and a turbine accommodating portion provided in the vehicle body.

According to the above aspect, the turbine accommodating portion is provided in the body of the motorcycle or tricycle. The turbine housing section has a housing chamber, a wind turbine, an air supply port, and an exhaust port. A wind turbine is housed in the housing chamber. The wind turbine is rotatably housed in the housing chamber about a rotation axis along the height direction of the vehicle body.

The air supply port is located in front of the accommodation chamber. Air is taken into the storage chamber through this air supply port. On the other hand, the exhaust port is located at the rear of the storage chamber and outside the air supply port in the width direction. From this exhaust port, the air inside the storage chamber is discharged outward in the width direction.

Here, when the vehicle runs, negative pressure is generated in the storage chamber due to the running wind flowing outside the exhaust port in the width direction. Due to this negative pressure, the air in the storage chamber is discharged from the exhaust port, and the traveling wind (air) is taken into the storage chamber from the air supply port. At this time, the wind turbine receives the traveling wind and rotates about a rotation axis along the height direction of the vehicle body. By utilizing the rotation of this wind turbine, it is possible to generate electricity.

In this way, by utilizing the negative pressure generated in the storage chamber by the traveling wind flowing outside the exhaust port in the width direction, the rotational efficiency of the wind turbine is increased. Therefore, power generation efficiency can be increased. Additionally, an increase in running resistance due to wind power generation is suppressed.

Additionally, the gyroscopic effect that accompanies the rotation of the wind turbine maintains the attitude of the vehicle. Therefore, the stability of the vehicle is improved.

A vehicle according to a second aspect is the vehicle according to the first aspect, in which the vehicle body is provided with a pair of the turbine accommodating portions lined up in the width direction.

According to the above aspect, the vehicle body is provided with a pair of turbine accommodating portions lined up in the width direction. A wind turbine is housed in each of the housing chambers of the pair of turbine housing sections. Each wind turbine rotates about a rotation axis along the height direction of the vehicle body as the vehicle travels. By utilizing the rotation of these wind turbines, it is possible to generate electricity. Therefore, in this aspect, the power generation efficiency is improved compared to the case where one turbine accommodating portion is provided in the vehicle body.

Furthermore, the posture of the vehicle body is easily maintained due to the gyro effect caused by the rotation of the wind turbines in the pair of turbine housing sections. Therefore, the stability of the vehicle is further improved.

In the vehicle according to a third aspect, in the vehicle according to the second aspect, the pair of turbine accommodating portions are symmetrical with respect to the front-rear direction of the vehicle body in a plane cross section viewed from the height direction of the vehicle body. Ru.

Thereby, in the pair of turbine accommodating parts, the gyro effect accompanying the rotation of the wind turbine tends to occur symmetrically with respect to the center line along the longitudinal direction of the vehicle body. Therefore, the stability of the vehicle is further improved.

A vehicle according to a fourth aspect is the vehicle according to the second aspect, in which the air supply port is formed on a front surface of the turbine housing section, and the exhaust port is formed on a side surface of the turbine housing section.

According to the above aspect, the air supply port is formed on the front surface of the turbine accommodating portion. On the other hand, the exhaust port is formed on the side surface of the turbine accommodating portion. This makes it easier to take the traveling wind into the storage chamber from the air supply port, and also makes it easier to discharge the traveling wind taken into the storage chamber from the exhaust port. Therefore, the rotational efficiency of the wind turbine is increased.

In the vehicle according to a fifth aspect, in the vehicle according to the fourth aspect, the side surface of the turbine accommodating portion is located inward in the width direction from the exhaust port forward in a plane cross section viewed from the height direction of the vehicle body. and reaches the air supply port.

According to the above aspect, the side surface of the turbine accommodating portion curves inward in the width direction from the exhaust port toward the front in a plane cross section viewed from the height direction of the vehicle body, and reaches the air supply port. As a result, when the vehicle runs, the running wind flows diagonally backward along the side surface of the turbine accommodating portion. Therefore, air resistance in the turbine accommodating portion is reduced.

Further, the traveling wind that has flowed diagonally backward along the side surface of the turbine accommodating portion passes through the outside of the exhaust port in the width direction. In other words, the traveling wind flowing along the side surface of the turbine accommodating portion is collected on the outside in the width direction of the exhaust port. As a result, the amount of traveling air passing outside the exhaust port in the width direction increases, so that the negative pressure generated in the storage chamber increases.

As a result, the efficiency of exhaust air from the exhaust port is further increased, and the efficiency of air supply from the air supply port is further increased. Therefore, the rotational efficiency of the wind turbine is further increased.

The wind direction guide portion protrudes from the side surface of the turbine housing portion. The wind direction guide portion has a guide surface that is inclined or curved toward the rear and outward in the width direction in a plane cross section viewed from the height direction of the vehicle body.

As a result, as the vehicle travels, the wind flowing backward along the side surface of the turbine accommodating portion is guided obliquely backward by the guide surface of the wind direction guide portion. This running wind pulls the air near the exhaust port outward in the width direction, increasing the negative pressure generated in the storage chamber.

As a result, the efficiency of exhaust air from the exhaust port is further increased, and the efficiency of air supply from the air supply port is further increased. Therefore, the rotational efficiency of the wind turbine is further increased.

A vehicle according to a seventh aspect is the vehicle according to the sixth aspect, in which the wind direction guide section is provided along the front edge section of the exhaust port.

Thereby, as the vehicle travels, the traveling wind that flows backward along the side surface of the turbine accommodating portion is guided outward in the width direction over a wider range by the guide surface of the wind direction guide portion. Therefore, the negative pressure generated in the storage chamber is increased, so that the rotational efficiency of the wind turbine is further increased.

A vehicle according to an eighth aspect is the vehicle according to the fourth aspect, including steps provided on both sides of the vehicle body in the width direction, and at least a part of the steps are located at the widthwise end of the side surface of the turbine accommodating portion.

Here, at least a portion of the step is located on the inner side in the width direction than the outermost end in the width direction on the side surface of the turbine accommodating portion. This prevents the wind flowing along the side surface of the turbine accommodating portion from hitting the legs (lower limbs) of the occupant on the steps when the vehicle is running. Therefore, air resistance due to the occupant's legs is reduced.

(wind turbine)
As shown in FIG. 4, the wind turbine 70 is a windmill that rotates around a rotation axis 72 along the height direction of the vehicle body 20 (arrow Z direction). This wind turbine 70 has a rotating shaft 72, a pair of side bases 74, and a plurality of rotary blades 76. The pair of side bases 74 face each other in the height direction of the vehicle body 20.

The pair of side bases 74 have a central portion 74A and a plurality of (four in this embodiment) support arm portions 74B. The central portion 74A is formed in a circular shape when viewed from the width direction of the turbine accommodating portion 42.

The plurality of support arm portions 74B extend radially outward from the outer peripheral portion of the central portion 74A centering on the rotation shaft 72 when viewed from the width direction of the turbine accommodating portion 42. The rotary blades 76 are bridged over the support arm portions 74B of the pair of side bases 74, respectively.

As shown in FIG. 3, the plurality of rotary blades 76 rotate about the rotation shaft 72 by receiving the traveling wind W supplied from the air supply port 54 through the air supply flow path 52. At this time, each of the rotary blades 76 is arranged such that, as shown by arrow P, the rotary blade 76 located in front of the rotary shaft 72 passes inside the rotary shaft 72 in the width direction and heads toward the rear of the rotary shaft 72.

Each rotor blade 76 is hollow and made of metal, resin, or the like. Further, the cross-sectional shape of each rotary blade 76 is a blade shape that generates a lift force directed outward in the radial direction of the rotary shaft 72 with respect to wind supplied from the front in the rotation direction.

Specifically, the outer surface 76S1 of each rotary blade 76 is a curved surface that curves convexly forward in the rotation direction. On the other hand, the inner surface 76S2 of each rotor blade 76 is a curved surface that curves convexly forward in the rotation direction. The curvature of the inner surface 76S2 of the rotor blade 76 is smaller than the curvature of the outer surface 76S1 of the rotor blade 76. As a result, a lift force directed outward in the radial direction of the rotary shaft 72 is generated in each rotary blade 76 with respect to the wind supplied from the front in the rotation direction.

(Generator)
As shown in FIG. 5, generators 80 are connected to both ends of the rotating shaft 72 of the wind turbine 70, respectively. Each generator 80 generates power as the pair of wind turbines 70 rotate. That is, the generator 80 converts the rotational energy of the pair of wind turbines 70 into electrical energy. Each generator 80 is connected to a battery 82 that stores the power generated by the generator 80.

Note that at least one power generator 80 can be connected to the rotating shaft 72 of the wind turbine 70. Further, the arrangement of the generator 80 can be changed as appropriate, and for example, the generator 80 may be attached to the vehicle body 20 instead of the turbine accommodating part 42.

(effect)
Next, the operation of this embodiment will be explained.

As shown in FIG. 3, when the vehicle 10 travels (moves forward), negative pressure is generated in the exhaust flow path 56 by the traveling wind W flowing outside the exhaust port 58 in the width direction. Due to this negative pressure, the air (traveling wind W) in the storage chamber 50 is discharged from the exhaust port 58, and the traveling wind (air) is taken into the storage chamber 50 from the air supply port 54. At this time, the wind turbine 70 receives the traveling wind W and rotates about a rotation axis 72 along the height direction of the vehicle body 20. As the wind turbine 70 rotates, the generator 80 generates electricity. Electric power generated by the generator 80 is supplied to the battery 82.

By utilizing the negative pressure generated in the storage chamber 50 by the traveling wind W flowing outside the exhaust port 58 in the width direction in this manner, the rotational efficiency of the wind turbine 70 is increased. Therefore, power generation efficiency can be increased. Additionally, an increase in running resistance due to wind power generation is suppressed. Furthermore, by supplying the electric power stored in the battery 82 to a motor (not shown) or the like as a drive source of the vehicle 10, the continuous traveling distance of the vehicle 10 can be increased.

Further, in this embodiment, a pair of turbine accommodating portions 42 are provided in the vehicle body 20. The pair of turbine accommodating portions 42 are arranged side by side in the width direction. The wind turbines 70 housed in the housing chambers 50 of the pair of turbine housing sections 42 rotate as the vehicle 10 travels. As these wind turbines 70 rotate, each generator 80 generates power.

Therefore, in this embodiment, the power generation efficiency is improved compared to the case where one turbine accommodating part 42 is provided in the vehicle body 20.

Further, the air supply port 54 is formed on the front surface 42F of the turbine accommodating portion 42. On the other hand, the exhaust port 58 is formed on the side surface 42S of the turbine accommodating portion 42. This makes it easier to take in the traveling wind W into the accommodation chamber 50 from the air supply port 54, and also makes it easier to discharge the traveling wind W taken into the accommodation chamber 50 from the exhaust port 58. Therefore, the rotational efficiency of the wind turbine 70 is increased.

Furthermore, the side surface 42S of the turbine accommodating portion 42 curves inward in the width direction from the exhaust port 58 toward the front in a plane cross section viewed from the height direction of the vehicle body 20, and reaches the air supply port 54. Thereby, when the vehicle 10 travels, the traveling wind W flows obliquely rearward along the side surface 42S of the turbine accommodating portion 42. Therefore, the air resistance of the turbine accommodating portion 42 is reduced.

Further, the traveling wind W flowing obliquely backward along the side surface 42S of the turbine accommodating portion 42 passes outside the exhaust port 58 in the width direction. That is, the traveling wind W flowing along the side surface 42S of the turbine accommodating portion 42 is collected outside the exhaust port 58 in the width direction. As a result, the amount of the traveling wind W passing through the outside of the exhaust port 58 in the width direction increases, so that the negative pressure generated in the storage chamber 50 increases.

As a result, the efficiency of exhaust air from the exhaust port 58 is further increased, and the efficiency of air supply from the air supply port 54 is further increased. Therefore, the rotational efficiency of the wind turbine 70 is further increased.

Further, a wind direction guide portion 60 is provided at the front edge portion 58F of the exhaust port 58 on the side surface 42S of the turbine accommodating portion 42. The wind direction guide section 60 protrudes from the side surface 42S of the turbine housing section 42. The wind direction guide portion 60 has a guide surface 60G that is inclined or curved toward the rear and outward in the width direction in a plan cross section viewed from the height direction of the vehicle body 20.

As a result, as the vehicle 10 travels, the traveling wind W flowing backward along the side surface 42S of the turbine accommodating portion 42 is directed diagonally backward (backward and outward in the width direction) by the guide surface 60G of the wind direction guide portion 60. You will be guided to. This traveling wind W pulls the air near the exhaust port 58 outward in the width direction, so that the negative pressure generated in the storage chamber 50 increases.

As a result, the efficiency of exhaust air from the exhaust port 58 is further increased, and the efficiency of air supply from the air supply port 54 is further increased. Therefore, the rotational efficiency of the wind turbine 70 is further increased.

Further, the wind direction guide portion 60 is provided along the front edge portion 58F of the exhaust port 58. As a result, the traveling wind W flowing backward along the side surface 42S of the turbine accommodating section 42 as the vehicle 10 travels is guided obliquely backward over a wider range by the guide surface 60G of the wind direction guide section 60. . Therefore, since the negative pressure generated in the storage chamber 50 increases, the rotational efficiency of the wind turbine 70 is further increased.

Further, the attitude of the vehicle body 20 is maintained by the gyro effect caused by the rotation of the wind turbine 70. Further, the turbine accommodating portion 42 is arranged between the front wheel 12 and the rear wheel 14. Thereby, the attitude of the vehicle body 20 is easily maintained by the gyroscopic effect of the wind turbine 70 as the vehicle 10 travels. Therefore, the stability of the vehicle body 20 is further improved.

Further, in this embodiment, as described above, the pair of turbine housing portions 42 are provided in the vehicle body 20 side by side in the width direction. As a result, the attitude of the vehicle body 20 is easily maintained by the gyroscopic effect accompanying the rotation of the wind turbines 70 in the pair of turbine accommodating portions 42 .

In particular, in the present embodiment, the pair of turbine accommodating portions 42 are symmetrical with respect to the center line C along the longitudinal direction of the vehicle body 20 in a plane cross section viewed from the height direction of the vehicle body 20. Thereby, in the pair of turbine accommodating parts 42, the gyroscopic effect accompanying the rotation of the wind turbine 70 tends to occur symmetrically with respect to the center line C of the vehicle body 20. Therefore, the stability of the vehicle 10 is further improved.

Furthermore, the steps 16 are provided on both sides of the vehicle body 20 in the width direction.
