Description

[Technical field]

[0001] The present invention relates to a vehicle. [Background technology]

[0002] There is a freight vehicle (truck) equipped with a wind power generator for vehicles (see, for example, Patent Document 1). The wind power generator for vehicles disclosed in Patent Document 1 is installed above the passenger compartment of the freight vehicle. This vehicle has rotors that rotate when catching the wind while traveling. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2022 / 269938 Summary of the Invention [Problem to be solved by the invention]

[0004] The vehicle wind power generating device disclosed in Patent Document 1 is applied to a freight vehicle, for example, but it is also desirable to generate wind power in motorcycles or three-wheeled motor vehicles.

[0005] In consideration of the above, the present disclosure has an object to generate wind power in a motorcycle or three-wheeled vehicle. [Means for solving the problem]

[0006] The vehicle of the first aspect comprises a motorcycle or three-wheeled motorcycle body, a storage compartment, a wind turbine rotatably stored in the storage compartment around a rotation axis along the height direction of the vehicle body, and a turbine storage section provided on the vehicle body, the turbine storage compartment having an air intake port located forward of the storage compartment for taking in air into the storage compartment, and an exhaust port located rearward of the storage compartment and widthwise outward of the air intake port for discharging air within the storage compartment widthwise outward.

[0007] According to the above aspect, a turbine housing section is provided on the body of the motorcycle or three-wheeled motor vehicle. The turbine housing section has a housing chamber, a wind turbine, an air inlet, and an exhaust port. The wind turbine is housed in the housing chamber. The wind turbine is housed in the housing chamber so as to be rotatable about a rotation axis extending along the height direction of the vehicle body.

[0008] The air supply port is located forward of the storage chamber. Air is taken into the storage chamber through the air supply port. Meanwhile, the exhaust port is located rearward of the storage chamber and outward of the air supply port in the width direction. Air within the storage chamber is exhausted outward in the width direction through the exhaust port.

[0009] When the vehicle is moving, negative pressure is generated in the accommodation chamber by the wind flowing on the widthwise outer side of the exhaust port. This negative pressure causes air in the accommodation chamber to be exhausted from the exhaust port, and the wind (air) is taken into the accommodation chamber from the air intake port. At this time, the wind turbine receives the wind and rotates around a rotation axis aligned in the height direction of the vehicle body. The rotation of this wind turbine can be used to generate electricity.

[0010] In this way, by utilizing the negative pressure generated in the housing by the wind flowing outside the width direction of the exhaust port, the rotation efficiency of the wind turbine is improved, and the power generation efficiency is improved. In addition, the increase in running resistance due to wind power generation is suppressed.

[0011] In addition, the gyro effect caused by the rotation of the wind turbine helps maintain the vehicle's position, improving the stability of the vehicle.

[0012] A vehicle according to a second aspect is the vehicle according to the first aspect, wherein the vehicle body is provided with a pair of the turbine accommodating portions aligned in a width direction.

[0013] According to the above aspect, the vehicle body is provided with a pair of turbine housing sections aligned in the width direction. A wind turbine is housed in each of the housing chambers of the pair of turbine housing sections. As the vehicle travels, each wind turbine rotates about a rotation axis aligned in the height direction of the vehicle body. Power can be generated by utilizing the rotation of these wind turbines. Therefore, in this aspect, power generation efficiency is improved compared to when a single turbine housing section is provided in the vehicle body.

[0014] In addition, the gyro effect caused by the rotation of the wind turbines in the pair of turbine housings makes it easier to maintain the position of the vehicle body, thereby further improving the stability of the vehicle.

[0015] A vehicle according to a third aspect is the vehicle according to the second aspect, wherein the pair of turbine housing portions are symmetrical with respect to the front-rear direction of the vehicle body in a plan cross section seen from a height direction of the vehicle body.

[0016] According to the above aspect, the pair of turbine housings are symmetrical with respect to the center line along the front-rear direction of the vehicle body in a planar cross section seen from the height direction of the vehicle body. This makes it easier for the gyro effect caused by the rotation of the wind turbines to occur symmetrically with respect to the center line along the front-rear direction of the vehicle body in the pair of turbine housings. This further improves the stability of the vehicle.

[0017] A vehicle according to a fourth aspect is the vehicle according to the second aspect, wherein the air intake port is formed on a front surface of the turbine accommodating section, and the exhaust port is formed on a side surface of the turbine accommodating section.

[0018] According to the above aspect, the air intake is formed on the front surface of the turbine housing. Meanwhile, the exhaust is formed on the side surface of the turbine housing. This makes it easier to take in wind from the air intake into the housing, and makes it easier to exhaust the wind taken into the housing from the exhaust. This improves the rotation efficiency of the wind turbine.

[0019] A vehicle according to a fifth aspect is the vehicle according to the fourth aspect, wherein the side surface of the turbine accommodating section, in a planar cross section viewed from the height direction of the vehicle body, curves inward in the width direction from the exhaust port forward to the air intake port.

[0020] According to the above aspect, the side surface of the turbine housing section curves inward in the width direction from the exhaust port toward the front and reaches the air intake port in a planar cross section seen from the height direction of the vehicle body. As a result, when the vehicle is traveling, the traveling wind flows diagonally rearward along the side surface of the turbine housing section. Therefore, the air resistance of the turbine housing section is reduced.

[0021] In addition, the traveling wind that flows diagonally backward along the side surface of the turbine housing portion passes through the widthwise outer side of the exhaust port. In other words, the traveling wind that flows along the side surface of the turbine housing portion is collected on the widthwise outer side of the exhaust port. This increases the amount of traveling wind passing through the widthwise outer side of the exhaust port, and the negative pressure generated in the housing chamber increases.

[0022] As a result, the efficiency of exhaust from the exhaust port is further improved, and the efficiency of air intake from the air intake port is further improved, thereby further improving the rotation efficiency of the wind turbine.

[0023] The vehicle of the sixth aspect is the vehicle of the fourth aspect, wherein a wind direction guide portion protruding from a front edge portion of the exhaust port on the side surface of the turbine housing portion is provided, and the wind direction guide portion has a guide surface that inclines or curves outward in the width direction toward the rear in a plan cross section viewed from the height direction of the vehicle body.

[0024] According to the above aspect, a wind direction guide is provided at a front edge of the exhaust port on a side surface of the turbine housing section. The wind direction guide protrudes from the side surface of the turbine housing section. The wind direction guide has a guide surface that is inclined or curved outward in the width direction toward the rear in a planar cross section seen from the height direction of the vehicle body.

[0025] As a result, as the vehicle travels, the wind that flows rearward along the side of the turbine housing is guided diagonally rearward by the guide surface of the air direction guide section. This wind pulls the air near the exhaust port outward in the width direction, increasing the negative pressure generated in the housing chamber.

[0026] As a result, the efficiency of exhaust from the exhaust port is further improved, and the efficiency of air intake from the air intake port is further improved, thereby further improving the rotation efficiency of the wind turbine.

[0027] A vehicle according to a seventh aspect is the vehicle according to the sixth aspect, wherein the airflow direction guide portion is provided along the front edge portion of the exhaust port.

[0028] According to the above aspect, the airflow direction guide is provided along the front edge of the exhaust port. As a result, the airflow that flows rearward along the side of the turbine housing as the vehicle travels is guided outward in the width direction over a wider range by the guide surface of the airflow direction guide. This increases the negative pressure generated in the housing, further improving the rotation efficiency of the wind turbine.

[0029] The vehicle of the eighth aspect is the vehicle of the fourth aspect, further comprising a step provided on each side of the vehicle body in the width direction, and at least a portion of the step is located widthwise inward of the outermost width end of the side of the turbine accommodating section.

[0030] According to the above aspect, the step is provided on each of both sides in the width direction of the vehicle body. Here, at least a part of the step is located inward in the width direction from the outermost end in the width direction of the side surface of the turbine housing section. This prevents the traveling wind flowing along the side surface of the turbine housing section from hitting the legs (lower legs) of the occupant on the step while the vehicle is traveling. Therefore, air resistance caused by the legs of the occupant is reduced.

[0031] The vehicle of the 9th aspect is the vehicle of the 1st aspect, further comprising front wheels arranged at the front of the vehicle body and rear wheels arranged at the rear of the vehicle body, and the turbine housing section is arranged between the front wheels and the rear wheels.

[0032] According to the above aspect, the front wheels are disposed at the front of the vehicle body, while the rear wheels are disposed at the rear of the vehicle body, and the turbine housing portion is disposed between the front wheels and the rear wheels.

[0033] By disposing the turbine housing between the front and rear wheels in this manner, the posture of the vehicle body is more easily maintained by the gyro effect of the wind turbine as the vehicle travels, thus improving the stability of the vehicle body.

[0034] The vehicle of the tenth aspect is the vehicle of the first aspect, further comprising a generator mounted on the vehicle body and generating electricity as the wind turbine rotates, and a battery mounted on the vehicle body and storing the electricity generated by the generator.

[0035] According to the above aspect, the generator generates electricity in response to the rotation of the wind turbine as the vehicle travels. The electricity generated by the generator is stored in the battery. The electricity stored in the battery can then be supplied to, for example, a motor or the like as a drive source for the vehicle, thereby making it possible to extend the continuous travel distance of the vehicle. Effect of the Invention

[0036] As described above, according to the present disclosure, wind power generation can be achieved in a motorcycle or three-wheeled motor vehicle. [Brief description of the drawings]

[0038] Hereinafter, an embodiment will be described with reference to the drawings.

[0039] (vehicle) 1 shows a vehicle 10 according to this embodiment. As an example, the vehicle 10 is a motorcycle. Also, as an example, the vehicle 10 is an electric vehicle. The vehicle 10 includes a vehicle body 20, a front wheel 12, and a rear wheel 14.

[0040] It should be noted that the vehicle 10 is not limited to an electric vehicle, but may be, for example, a hybrid vehicle, a fuel cell vehicle, or a gasoline vehicle.

[0041] The vehicle body 20 is disposed between the front wheels 12 and the rear wheels 14. The vehicle body 20 is covered with a side cover 22. The vehicle body 20 has a main frame 20A and a seat frame (rear frame) 20B.

[0042] The main frame 20A constitutes the front part of the body 20, and supports a motor (not shown) as a drive source. A head pipe (not shown) to which a front fork 24 is attached is provided on the front end side of the main frame 20A. The main frame 20A is supported by the front wheel 12 disposed in front of the body 20 via the front fork 24.

[0043] A swing arm 26 is attached to the rear end of the main frame 20A via a pivot (not shown). The rear end of the main frame 20A is supported by the rear wheel 14 disposed at the rear of the vehicle body 20 via the swing arm 26. The rear wheel 14 is connected to the motor described above via a drive shaft (not shown) or the like, and is driven to rotate by the motor.

[0044] The seat frame 20B constitutes the rear of the vehicle body 20. This seat frame 20B extends rearward from the main frame 20A and supports the vehicle seat 28. The seat frame 20B also supports a battery 82 (see FIG. 5), a rear fender 30 that covers the rear wheel 14 from above, and the like.

[0045] The main frame 20A is provided with a pair of steps 16 on which an occupant seated in the vehicle seat 28 places his / her feet. The pair of steps 16 extend outward in the width direction from the main frame 20A. A brake pedal, a shift pedal, or the like (not shown) is provided in front of the steps 16.

[0046] A pair of wind power generating devices 40 for vehicles are provided at the front of the vehicle body 20 constructed in this manner.

[0047] (Wind power generation equipment for vehicles) As shown in Fig. 1, the pair of wind power generators 40 for vehicles are wind power generators that generate power by utilizing wind W generated by the vehicle 10 while the vehicle 10 is traveling. As shown in Fig. 2, the pair of wind power generators 40 for vehicles are arranged side by side in the width direction of the vehicle 10.

[0048] The pair of vehicle wind power generating devices 40 includes a turbine housing 42, a pair of wind turbines 70, a generator 80 (see FIG. 5), and a battery 82 (see FIG. 5).

[0049] In addition, the arrow X shown in each drawing indicates the front (front of the vehicle) of the vehicle 10 (vehicle body 20) and the wind power generation device 40 (turbine housing section 42). The arrow Y indicates the outside (right side) in the width direction (vehicle width direction) of the vehicle 10 (vehicle body 20) and the wind power generation device 40 (turbine housing section 42). Furthermore, the arrow Z indicates the upper side (upper side of the vehicle) of the vehicle 10 (vehicle body 20) and the wind power generation device 40 (turbine housing section 42).

[0050] The pair of vehicle-mounted wind power generators 40 are configured symmetrically with respect to a center line C along the front-rear direction of the vehicle 10 (vehicle body 20). Therefore, the configuration of the vehicle-mounted wind power generator 40 disposed on the right side of the center line C of the vehicle 10 will be described below, and a description of the vehicle-mounted wind power generator 40 disposed on the left side of the center line C of the vehicle 10 will be omitted.

[0051] (Turbine housing) 3, the turbine housing section 42 is a housing that houses a wind turbine 70 therein. The turbine housing section 42 has a side wall section 44 that forms a side surface of the vehicle 10. The turbine housing section 42 also has an accommodation chamber 50, an air intake passage 52, an air intake port 54, an exhaust passage 56, and an exhaust port 58.

[0052] (Containment Cell) The accommodation chamber 50 is disposed in the middle in the front-rear direction of the turbine accommodation section 42. The accommodation chamber 50 is formed in a cylindrical shape along the height direction of the vehicle body 20. In other words, the accommodation chamber 50 is formed in a circular shape in a plan cross section seen from the height direction of the vehicle body 20.

[0053] Specifically, a widthwise outer wall surface 50A of the storage chamber 50 is curved into an arc shape. A widthwise inner wall surface 50B of the storage chamber 50 is curved outward in the widthwise direction toward the rear. The wall surface 50B of the storage chamber 50 is continuous with widthwise inner wall surfaces 52B, 56B of the air intake passage 52 and the exhaust passage 56 described later.

[0054] When the vehicle 10 is traveling, a traveling wind W is supplied to the accommodation chamber 50 from the air intake port 54 through the air intake passage 52. The traveling wind W supplied to the accommodation chamber 50 is exhausted from the exhaust port 58 via the exhaust passage 56.

[0055] (air supply port) The air intake port 54 is formed on the front surface 42F of the turbine housing 42, and is located in front of the housing chamber 50. The air intake port 54 faces forward and is formed along the height direction of the vehicle 10. The air intake port 54 is disposed closer to the inside in the width direction of the housing chamber 50 (toward the center in the width direction of the vehicle 10). The air intake port 54 is connected to the front end of the housing chamber 50 via the air intake flow path 52.

[0056] (Air supply flow path) The air intake passage 52 is disposed in front of the accommodation chamber 50. The air intake passage 52 is formed along the height direction of the vehicle 10. A rear end of the air intake passage 52 is connected to an inner side of the accommodation chamber 50 in the width direction. The air intake passage 52 extends forward from the inner side of the accommodation chamber 50 in the width direction, and connects the accommodation chamber 50 to the air intake port 54. A widthwise outer wall surface 52A and a widthwise inner wall surface 52B of the air intake passage 52 are aligned along the front-rear direction.

[0057] (Exhaust port) The exhaust port 58 is formed in the side surface 42S (side wall portion 44) at the rear of the turbine housing portion 42, and is located rearward of the housing chamber 50 and outward in the width direction of the air intake port 54. The exhaust port 58 faces diagonally rearward (rearward and outward in the width direction) and is formed along the height direction of the vehicle 10. The exhaust port 58 is connected to the rear end portion of the housing chamber 50 via an exhaust flow path 56.

[0058] The direction of the exhaust port 58 is not limited to the diagonally rearward direction, but may be, for example, toward the outside in the width direction.

[0059] Here, the side surface 42S of the turbine housing section 42, in a planar cross section seen from the height direction of the vehicle body 20, is a curved surface that curves inward in the width direction forward from the front edge portion 58F of the exhaust port 58 and reaches the outer edge portion 54S on the outer side in the width direction of the air intake port 54. This side surface 42S of the turbine housing section 42 also functions as a cowl that reduces air resistance associated with the travel of the vehicle 10.

[0060] It should be noted that the side surface 42S of the turbine housing section 42 only needs to be curved inward in the width direction from the front edge portion 58F of the exhaust port 58 forward in a planar cross section viewed from the height direction of the vehicle body 20. Therefore, the side surface 42S of the turbine housing section 42 may partially include straight portions, inclined portions, uneven portions, etc. In addition, the side surface 42S of the turbine housing section 42 is not limited to the curved surface described above, and may be, for example, an inclined surface inclined with respect to the front-rear direction of the vehicle 10.

[0061] (Exhaust flow path) The exhaust flow path 56 is disposed rearward of the accommodation chamber 50. A front end of the exhaust flow path 56 is connected to an inner portion of the accommodation chamber 50 in the width direction. The exhaust flow path 56 curves outward in the width direction from the accommodation chamber 50 toward the rear, and connects the accommodation chamber 50 to an exhaust port 58. A wall surface 56A on the outer side in the width direction and a wall surface 56B on the inner side in the width direction of the exhaust flow path 56 are curved surfaces that curve outward in the width direction toward the rear.

[0062] (Wind direction guide) An airflow direction guide portion 60 is provided at a front edge portion 58F of the exhaust port 58 on the side surface 42S of the turbine housing portion 42. The airflow direction guide portion 60 is provided along the front edge portion 58F of the exhaust port 58. The airflow direction guide portion 60 also protrudes from the side surface 42S of the turbine housing portion 42. The airflow direction guide portion 60 has a guide surface 60G.

[0063] Guide surface 60G is an inclined surface that inclines rearward and outward in the width direction in a planar cross section seen from the height direction of vehicle body 20. This guide surface 60G guides traveling wind W that flows rearward along side surface 42S of turbine housing section 42 while vehicle 10 is traveling diagonally rearward (rearward and outward in the width direction).

[0064] The guide surface 60G may be a curved surface that curves rearward and outward in the width direction in a planar cross section seen from the height direction of the vehicle body 20. The airflow direction guide portion 60 may be omitted.

[0065] Here, a step 16 is provided behind the exhaust port 58. This step 16 is located inward in the width direction from the outermost end in the width direction on the side surface 42S of the turbine housing section 42. More specifically, the entire step 16 is located inward in the width direction from the rear end 60G1 of the guide surface 60G of the airflow direction guide section 60 provided on the side surface 42S of the turbine housing section 42. This prevents the running wind W flowing diagonally backward along the guide surface 60G of the airflow direction guide section 60 from hitting the legs of the occupant positioned on the step 16 when the vehicle 10 is running.

[0066] In addition, when the wind direction guide portion 60 is not provided on the side surface 42S of the turbine accommodating portion 42, the outermost end in the width direction on the side surface 42S of the turbine accommodating portion 42 is, for example, the front edge portion 58F of the exhaust port 58. In addition, at least a part of the step 16 may be positioned inward in the width direction from the outermost end in the width direction on the side surface 42S of the turbine accommodating portion 42.

[0067] (Wind Turbines) 4, the wind turbine 70 is a windmill that rotates about a rotation shaft 72 that runs along the height direction of the vehicle body 20 (the direction of the arrow Z). The wind turbine 70 has the rotation shaft 72, a pair of side bases 74, and a plurality of rotors 76. The pair of side bases 74 face each other in the height direction of the vehicle body 20.

[0068] 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.

[0069] When viewed in the width direction of the turbine accommodating section 42, the multiple support arm portions 74B extend radially outward from the outer periphery of the central portion 74A around the rotating shaft 72. Rotating blades 76 are respectively bridged across the support arm portions 74B of the pair of side bases 74.

[0070] 3, the rotors 76 rotate about the rotary shaft 72 by receiving the traveling wind W supplied from the air intake port 54 through the air intake passage 52. At this time, as shown by the arrow P, each rotor 76 rotates such that the rotor 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.

[0071] Each rotor 76 is formed into a hollow shape from metal, resin, etc. The cross-sectional shape of each rotor 76 is a blade shape that generates lift toward the radial outside of the rotor shaft 72 in response to wind supplied from the front in the rotation direction.

[0072] Specifically, the outer surface 76S1 of each rotor 76 is a curved surface that is convexly curved forward in the direction of rotation. On the other hand, the inner surface 76S2 of each rotor 76 is a curved surface that is convexly curved forward in the direction of rotation. The curvature of the inner surface 76S2 of the rotor 76 is smaller than the curvature of the outer surface 76S1 of the rotor 76. As a result, each rotor 76 generates lift toward the radial outside of the rotor shaft 72 in response to wind supplied from the front in the direction of rotation.

[0073] (Generator) As shown in Fig. 5, generators 80 are connected to both ends of the rotating shaft 72 of the wind turbines 70. Each generator 80 generates power as the pair of wind turbines 70 rotates. In other words, the generators 80 convert the rotational energy of the pair of wind turbines 70 into electrical energy. A battery 82 that stores the power generated by the generator 80 is connected to each generator 80.

[0074] At least one generator 80 can be connected to the rotating shaft 72 of the wind turbine 70. The location 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 housing section 42.

[0075] (action) Next, the operation of this embodiment will be described.

[0076] As shown in Fig. 3, when the vehicle 10 travels (forward), a negative pressure is generated in the exhaust flow passage 56 by a traveling wind W flowing on the outer side in the width direction of the exhaust port 58. This negative pressure causes air (traveling wind W) in the accommodation chamber 50 to be exhausted from the exhaust port 58, and also causes the traveling wind (air) to be taken into the accommodation chamber 50 from the air intake port 54. At this time, the wind turbine 70 receives the traveling wind W and rotates about a rotation axis 72 aligned in the height direction of the vehicle body 20. As the wind turbine 70 rotates, the generator 80 generates electricity. The electricity generated by the generator 80 is supplied to a battery 82.

[0077] In this way, by utilizing the negative pressure generated in the accommodation chamber 50 by the traveling wind W flowing outside the exhaust port 58 in the width direction, the rotation efficiency of the wind turbine 70 is improved. Therefore, the power generation efficiency can be improved. Also, an increase in the running resistance caused by wind power generation is suppressed. Furthermore, by supplying the electric power stored in the battery 82 to a motor or the like (not shown) serving as a drive source of the vehicle 10, the continuous running distance of the vehicle 10 can be increased.

[0078] In this embodiment, a pair of turbine housing sections 42 are provided on the vehicle body 20. The pair of turbine housing sections 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 each rotate as the vehicle 10 travels. As the wind turbines 70 rotate, the generators 80 each generate electricity.

[0079] Therefore, in this embodiment, power generation efficiency is improved compared to a case where one turbine accommodating portion 42 is provided in the vehicle body 20.

[0080] Moreover, the air intake port 54 is formed on the front surface 42F of the turbine housing section 42. Meanwhile, the exhaust port 58 is formed on the side surface 42S of the turbine housing section 42. This makes it easier for the traveling wind W to be taken into the housing chamber 50 from the air intake port 54, and also makes it easier for the traveling wind W taken into the housing chamber 50 to be discharged from the exhaust port 58. This improves the rotation efficiency of the wind turbine 70.

[0081] Furthermore, in a planar cross section seen from the height direction of the vehicle body 20, the side surface 42S of the turbine housing section 42 curves inward in the width direction from the exhaust port 58 toward the front, and reaches the air intake port 54. As a result, when the vehicle 10 is traveling, the traveling wind W flows diagonally backward along the side surface 42S of the turbine housing section 42. Therefore, the air resistance of the turbine housing section 42 is reduced.

[0082] Furthermore, the traveling wind W that flows diagonally rearward along the side surface 42S of the turbine housing section 42 passes through the widthwise outer side of the exhaust port 58. That is, the traveling wind W that flows along the side surface 42S of the turbine housing section 42 is collected on the widthwise outer side of the exhaust port 58. As a result, the amount of the traveling wind W that passes through the widthwise outer side of the exhaust port 58 increases, and the negative pressure generated in the housing chamber 50 increases.

[0083] As a result, the efficiency of exhaust from the exhaust port 58 is further improved, and the efficiency of intake from the intake port 54 is further improved. Therefore, the rotation efficiency of the wind turbine 70 is further improved.

[0084] Further, an airflow direction guide portion 60 is provided at a front edge portion 58F of the exhaust port 58 on the side surface 42S of the turbine housing portion 42. The airflow direction guide portion 60 protrudes from the side surface 42S of the turbine housing portion 42. The airflow direction guide portion 60 has a guide surface 60G that is inclined or curved outward in the width direction toward the rear in a planar cross section seen from the height direction of the vehicle body 20.

[0085] As a result, as the vehicle 10 travels, the traveling wind W that flows rearward along the side surface 42S of the turbine housing section 42 is guided diagonally rearward (rearward and outward in the width direction) by the guide surface 60G of the air direction guide section 60. The traveling wind W pulls the air near the exhaust port 58 outward in the width direction, so that the negative pressure generated in the housing chamber 50 increases.

[0086] As a result, the exhaust efficiency from the exhaust port 58 is further improved, and the air intake efficiency from the air intake port 54 is further improved. Therefore, the rotation efficiency of the wind turbine 70 is further improved.

[0087] In addition, the wind direction guide portion 60 is provided along the front edge portion 58F of the exhaust port 58. As a result, the running wind W that flows rearward along the side surface 42S of the turbine housing portion 42 as the vehicle 10 travels is guided obliquely rearward over a wider range by the guide surface 60G of the wind direction guide portion 60. This increases the negative pressure generated in the housing chamber 50, further improving the rotation efficiency of the wind turbine 70.

[0088] The posture of the vehicle body 20 is maintained by the gyro effect caused by the rotation of the wind turbine 70. Furthermore, the turbine housing 42 is disposed between the front wheels 12 and the rear wheels 14. This makes it easier to maintain the posture of the vehicle body 20 by the gyro effect of the wind turbine 70 caused by the running of the vehicle 10. Therefore, the stability of the vehicle body 20 is further improved.

[0089] In this embodiment, as described above, the pair of turbine housing sections 42 are provided side by side in the width direction on the vehicle body 20. This makes it easier to maintain the posture of the vehicle body 20 by the gyro effect caused by the rotation of the wind turbines 70 in the pair of turbine housing sections 42.

[0090] Particularly in this embodiment, the pair of turbine housing sections 42 are symmetrical with respect to a center line C along the front-rear direction of the vehicle body 20 in a planar cross section seen from the height direction of the vehicle body 20. This makes it easier for the gyro effect caused by the rotation of the wind turbine 70 to occur symmetrically with respect to the center line C of the vehicle body 20 in the pair of turbine housing sections 42. This further improves the stability of the vehicle 10.

[0091] Further, the step 16 is provided on each of both sides in the width direction of the vehicle body 20. Here, the step 16 is located on the width direction inner side of the outermost end in the width direction on the side surface 42S of the turbine housing section 42. More specifically, in this embodiment, the entire step 16 is located on the width direction inner side of the rear end 60G1 of the guide surface 60G of the airflow direction guide section 60 provided on the side surface 42S of the turbine housing section 42.

[0092] This prevents the traveling wind W flowing along the guide surface 60G of the airflow direction guide portion 60 from hitting the legs (lower legs) of the occupant standing on the step 16 while the vehicle 10 is traveling. Therefore, the air resistance caused by the legs of the occupant is reduced.

[0093] (Modification) Next, a modification of the above embodiment will be described.

[0094] In the above embodiment, the pair of vehicle wind power generators 40 (turbine housing sections 42) are configured symmetrically with respect to the center line C along the front-rear direction of the vehicle 10. However, the pair of vehicle wind power generators 40 (turbine housing sections 42) may be configured asymmetrically with respect to the center line C of the vehicle 10.

[0095] In the above embodiment, a pair of vehicle wind power generators 40 (turbine housing portions 42) are provided on the vehicle body 20. However, the vehicle body 20 may be provided with at least one vehicle wind power generator 40 (turbine housing portion 42).

[0096] In the above embodiment, the vehicle 10 is a motorcycle. However, the vehicle is not limited to a motorcycle, and may be a three-wheeled vehicle. In this case, the vehicle may be a three-wheeled vehicle with one front wheel and two rear wheels, or a three-wheeled vehicle with two front wheels and one rear wheel.

[0097] Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and one embodiment and various modified examples may be used in appropriate combination, and it is of course possible to implement the present invention in various forms without departing from the gist of the present invention.
