Description

[Technical field]

[0001] The present disclosure relates to a wind power generating device for a vehicle and a freight 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 wind power generator for vehicles has rotors that rotate when catching the wind while the vehicle is running. [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] In the wind power generating device for vehicles disclosed in Patent Document 1, there is room for further improvement in order to increase the power generation efficiency.

[0005] In consideration of the above, the present disclosure has an object to improve power generation efficiency in a vehicle wind power generation device installed above a passenger compartment of a freight vehicle. [Means for solving the problem]

[0006] The vehicle wind power generation device of the first embodiment has a wind turbine, a storage chamber that houses the wind turbine so that it can rotate around a rotation axis along the width direction, an air intake port located forward of the storage chamber and taking in air into the storage chamber, and an exhaust port located rearward of the storage chamber and above the air intake port and discharging the air in the storage chamber upward, and is equipped with a casing that is installed on the passenger compartment of a cargo vehicle, and a fairing vane that is provided on the casing, positioned above the exhaust port, and curved convexly downward when viewed in the width direction of the casing.

[0007] According to the above aspect, the housing is installed on the passenger compartment of the cargo vehicle with the air intake facing forward. When the cargo vehicle travels in this state, negative pressure is generated in the accommodation chamber by the running wind flowing above the exhaust port, and the air in the accommodation chamber is discharged upward from the exhaust port, while the running wind (air) is taken into the accommodation chamber from the air intake port. At this time, the wind turbine receives the running wind and rotates around a rotation axis along the width direction of the housing. The rotation of this wind turbine can be used to generate electricity.

[0008] The housing is also provided with airflow fins. The airflow fins are disposed above the exhaust port. When the freight vehicle moves, the wind that flows along the upper surface of the housing passes above and below the airflow fins.

[0009] Here, the airflow wing is curved in a downward convex shape when viewed from the width direction of the housing. As a result, the airflow passing under the airflow wing flows along the underside of the curved airflow wing due to the Coanda effect, and flows diagonally upward from the rear end of the airflow wing. As a result, negative pressure is created on the underside of the airflow wing, i.e., near the exhaust port, and the airflow inside the accommodation chamber is pulled diagonally upward from the exhaust port.

[0010] This improves the exhaust efficiency of the wind passing through the accommodation chamber and being exhausted from the exhaust port, which in turn improves the supply efficiency of the wind supplied to the accommodation chamber from the air inlet, thereby improving the rotation efficiency of the wind turbine and thus the power generation efficiency.

[0011] In addition, by covering the exhaust port from above with the airfoil, for example, rain or snow is prevented from entering the accommodation chamber through the exhaust port. Furthermore, even if the wind turbine becomes detached from the housing while the freight car is traveling, the wind turbine interferes with the airfoil, preventing the wind turbine from falling.

[0012] The second aspect of the wind turbine generator for vehicles is the wind turbine generator for vehicles of the first aspect, wherein the exhaust port is formed on the upper surface of the housing, and the front end of the air guide wing is located forward of the leading edge of the exhaust port and above the upper surface of the housing.

[0013] According to the above aspect, the exhaust port is formed on the upper surface of the housing. Furthermore, the front end of the airflow guide wing is located forward of the leading edge of the exhaust port and above the upper surface of the housing. This prevents the traveling wind discharged from the exhaust port from passing over the front end of the airflow guide wing and flowing around to the upper surface side of the airflow guide wing. This further improves the exhaust efficiency of the traveling wind discharged from the exhaust port.

[0014] A wind turbine generator for vehicles according to a third aspect is the wind turbine generator for vehicles according to the second aspect, wherein an upper surface of the housing curves downward and forward from a front edge of the exhaust port.

[0015] According to the above aspect, the upper surface of the housing is curved downward from the front edge of the exhaust port toward the front. As a result, when the freight vehicle moves, the running wind flows obliquely upward along the upper surface of the housing. Therefore, the air resistance of the housing is reduced.

[0016] In addition, the traveling wind that flows diagonally upward along the upper surface of the housing passes above and below the airflow stabilization wing. In other words, the traveling wind that flows along the upper surface of the housing is collected by the airflow stabilization wing. This increases the amount of traveling wind passing above and below the airflow stabilization wing, so that, as described above, the traveling wind in the accommodation chamber is more likely to be pulled diagonally upward from the exhaust port. This further improves the exhaust efficiency from the exhaust port and the intake efficiency from the intake port.

[0017] A wind turbine generator for vehicles according to a fourth aspect is the wind turbine generator for vehicles according to the third aspect, wherein side wall portions on both sides of the housing each have a protrusion that protrudes upward beyond an upper surface of the housing.

[0018] According to the above aspect, the side wall portions on both sides of the housing each have a protrusion that protrudes upward beyond the top surface of the housing.

[0019] When a freight vehicle is moving, the wind that flows diagonally upward along the top surface of the housing is faster than the wind that flows backward along the side of the housing, and the air pressure on the top side of the housing becomes lower than the air pressure on the side of the housing. As a result, a vortex is generated that wraps around from the side to the top of the housing, which can increase the air resistance of the housing.

[0020] In contrast, in this embodiment, as described above, the side wall of the housing has a protruding portion that protrudes upward from the upper surface of the housing. This protruding portion prevents air from flowing from the side surface of the housing to the upper surface. As a result, the generation of vortexes that flow from the side surface of the housing to the upper surface is suppressed. Therefore, the air resistance of the housing is reduced.

[0021] A wind power generator for vehicles according to a fifth aspect is the wind power generator for vehicles according to the fourth aspect, wherein the protrusion extends from the front end side to the rear end side on the upper surface of the housing.

[0022] According to the above aspect, the protrusion extends from the front end side to the rear end side on the upper surface of the housing. This suppresses the generation of vortexes that wrap around from the side side to the upper surface of the housing from the front end side to the rear end side on the upper surface of the housing when the freight vehicle is traveling. This further reduces the air resistance of the housing.

[0023] A wind turbine generator for vehicles according to a sixth aspect is the wind turbine generator for vehicles according to the fourth aspect, wherein the air guide vanes are bridged across the protruding portions on both sides.

[0024] According to the above aspect, the airflow stabilizer is bridged across the protruding portions on both sides. This airflow stabilizer enhances the rigidity of the protruding portions, thereby suppressing vibrations of the protruding portions that occur when the freight car is traveling.

[0025] The wind turbine generator for a vehicle of the seventh aspect is the wind turbine generator for a vehicle of the first aspect, further comprising an angle adjustment mechanism that is provided on the housing, rotatably supports the air guide vane around a rotation axis along the width direction of the housing, and holds the air guide vane at a predetermined rotation angle.

[0026] According to the above aspect, the housing is provided with an angle adjustment mechanism. The angle adjustment mechanism rotatably supports the airflow stator around a rotation axis along the width direction of the housing and holds the airflow stator at a predetermined rotation angle. By using this angle adjustment mechanism, for example, the rotation angle of the airflow stator can be adjusted so that the rear end of the airflow stator is at the same height as the upper surface of the bed of the freight vehicle, thereby reducing the air resistance of the bed.

[0027] The wind turbine generator for vehicles according to an eighth aspect is the wind turbine generator for vehicles according to the first aspect, wherein a rear end portion of the airflow straightening vane is positioned higher than a front end portion of the airflow straightening vane.

[0028] According to the above aspect, the rear end of the airfoil is located higher than the front end of the airfoil. This makes it easier for the wind passing under the airfoil to flow obliquely upward from the rear end of the airfoil when the freight car is traveling. This further improves the exhaust efficiency from the exhaust port and the intake efficiency from the intake port.

[0029] The ninth aspect of the wind power generation device for vehicles is the wind power generation device for vehicles of the first aspect, wherein the housing has a partition wall portion that divides the storage chamber into a plurality of separate storage chambers in the width direction of the housing, and each of the separate storage chambers houses a wind turbine, and the front end side of the partition wall portion tapers toward the front in a cross-sectional plan view, and the rear end side of the partition wall portion tapers toward the rear in a cross-sectional plan view.

[0030] According to the above aspect, the housing has a partition wall portion. The partition wall portion divides the accommodation chamber in the width direction of the housing into a plurality of divided accommodation chambers. Each of the divided accommodation chambers accommodates a wind turbine.

[0031] Here, the front end of the partition wall is tapered toward the front in a plan view. As a result, when the freight vehicle is traveling, the wind generated by the traveling of the vehicle supplied from the air intake port to the accommodation chamber is guided by the front end of the partition wall to the wind turbines accommodated in the separate accommodation chambers on both sides of the partition wall. This further increases the rotation efficiency of the wind turbines.

[0032] In addition, the rear end of the partition wall is tapered toward the rear in a plan cross-sectional view, which makes it easier for wind to flow from the separate storage compartments on both sides of the partition wall toward the exhaust port when the freight vehicle is traveling, thereby further improving the rotation efficiency of the wind turbine.

[0033] The wind power generating device for vehicles according to a tenth aspect is the wind power generating device for vehicles according to the ninth aspect, further comprising a generator that is provided inside the partition wall and generates electricity in conjunction with rotation of the wind turbine.

[0034] According to the above aspect, the generator that generates electricity in association with the rotation of the wind turbine is provided inside the partition wall. By accommodating the generator inside the partition wall in this manner, it is possible to reduce the size of the housing.

[0035] The eleventh aspect of the wind power generator for vehicles is the wind power generator for vehicles of the first aspect, wherein the side wall portions on both sides of the housing are provided with air intake guide portions that are located forward of the storage chamber and that, when viewed in a cross-sectional view, incline inward in the width direction of the housing toward the rear.

[0036] According to the above aspect, the housing has side walls on both sides provided with an air intake guide portion. The air intake guide portion is located forward of the accommodation chamber and is inclined inward in the width direction of the housing toward the rear in a plan cross-sectional view.

[0037] As a result, when the freight vehicle is traveling, the wind generated by the traveling is supplied from the air intake port along both side walls of the housing to the accommodation chamber, and is guided by the air intake guide to the inside of the housing in the width direction, i.e., to the wind turbine accommodated in the accommodation chamber, thereby further improving the rotation efficiency of the wind turbine.

[0038] A twelfth aspect of the present invention is the wind power generator for vehicles of the first aspect, wherein side wall portions on both sides of the accommodation chamber are inclined rearward and outward in the width direction of the housing in a plan cross-sectional view.

[0039] According to the above aspect, the side walls of the storage compartment are inclined rearward and outward in the width direction of the housing in a plan view. This makes it easier for the wind to flow from the storage compartment toward the exhaust port when the freight vehicle is traveling. This further increases the rotation efficiency of the wind turbine.

[0040] The thirteenth aspect of the wind power generation device for a vehicle is the wind power generation device for a vehicle of the first aspect, and is further provided with an opening / closing plate whose lower end is rotatably supported on the housing around a pivot axis extending in the width direction of the housing and which opens and closes the air intake port, the housing has an air intake flow path connecting the air intake port and the storage chamber, and the opening / closing plate is inclined relative to the floor surface of the air intake flow path when rotated toward the storage chamber to open the air intake port.

[0041] According to the above aspect, the device includes an opening / closing plate that opens and closes the air intake port. The opening / closing plate has a lower end that is supported by the housing so as to be rotatable around a rotation axis that extends in the width direction of the housing. The housing has an air intake flow path that connects the air intake port and the storage chamber. The opening / closing plate is inclined with respect to the floor surface of the air intake flow path when rotated toward the storage chamber to open the air intake port.

[0042] When the freight vehicle is traveling, if the wind flows along the floor surface of the air intake passage, air resistance increases due to friction with the floor surface and the like.

[0043] In contrast, in this embodiment, as described above, the opening / closing plate is inclined with respect to the floor surface of the air intake passage when it is rotated toward the accommodation compartment to open the air intake port. As a result, when the freight vehicle is traveling, the running wind supplied to the air intake passage flows obliquely upward along the opening / closing plate and moves away from the floor surface of the air intake passage. Therefore, air resistance such as friction generated between the running wind and the floor surface is reduced.

[0044] The wind power generating apparatus for vehicles according to a fourteenth aspect is the wind power generating apparatus for vehicles according to the first aspect, further comprising an outdoor unit for air conditioning.

[0045] According to the above aspect, the vehicle includes an outdoor unit for air conditioning, whereby, for example, the outdoor unit can be operated by electric power generated by the wind power generation device for a vehicle.

[0046] A cargo vehicle according to a fifteenth aspect comprises a passenger cabin, a luggage compartment arranged behind the passenger cabin and having an upper surface higher than an upper surface of the passenger cabin, and a vehicle wind power generation device according to any one of the first to fourteenth aspects installed above the passenger cabin.

[0047] According to the above aspect, by installing the vehicle wind power generation device above the passenger compartment, it is possible to reduce the air resistance of the cargo bed and generate electricity by utilizing the wind generated by the cargo vehicle as it travels. Effect of the Invention

[0048] As described above, according to the present disclosure, it is possible to improve the power generation efficiency in a vehicle wind turbine generator installed above a passenger compartment of a freight vehicle. [Brief description of the drawings]

[Figure 8] 8 is a cross-sectional view taken along line 8-8 in FIG. 7. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0050] Hereinafter, one embodiment will be described with reference to the drawings.

[0051] (Freight cars) 1 shows a cargo vehicle 10 equipped with a wind power generating device 20 for vehicles according to this embodiment. The cargo vehicle (lorry) 10 is, for example, a van-type truck. The cargo vehicle 10 includes a vehicle body 12 and a luggage compartment 16.

[0052] The front end side of the vehicle body 12 is defined as a passenger compartment 14. A driver's seat is provided inside the passenger compartment 14. A luggage compartment 16 is disposed behind the passenger compartment 14.

[0053] The luggage compartment (luggage platform) 16 is installed on the rear of the vehicle body 12. The luggage compartment 16 is formed, for example, in a box shape and is capable of accommodating luggage therein. An upper surface 16U of the luggage compartment 16 is disposed at a higher position than an upper surface 14U of the passenger compartment 14. In other words, a step is formed between the upper surface 14U of the passenger compartment 14 and the upper surface 16U of the luggage compartment 16. A wind power generation device 20 for a vehicle is installed on the upper surface 14U of the passenger compartment 14 so as to fill the step.

[0054] The luggage compartment 16 is a concept that also includes a box-shaped container of a refrigerated vehicle or a freezer vehicle. The cargo vehicle 10 may be, for example, an electric vehicle, a hybrid vehicle, a fuel cell vehicle, or a gasoline vehicle.

[0055] (Wind power generation equipment for vehicles) As shown in Fig. 1, the wind power generator 20 for vehicles is a wind power generator that is installed on the upper surface 14U of the passenger compartment 14 of the freight vehicle 10 and generates electricity by utilizing wind W generated by the movement of the freight vehicle 10. As shown in Fig. 2, the wind power generator 20 for vehicles includes a housing 30, a generator 60 (see Fig. 5), a pair of wind turbines 70 (see Fig. 5), a baffle 80, and an opening / closing plate 90.

[0056] In addition, the arrow X shown in each drawing indicates the front (front of the vehicle) of the freight vehicle 10 and the wind power generation device 20 (housing 30). The arrow Y indicates the outside in the width direction (vehicle width direction) of the freight vehicle 10 and the wind power generation device 20 (housing 30). Furthermore, the arrow Z indicates the top (top of the vehicle) of the freight vehicle 10 and the wind power generation device 20 (housing 30).

[0057] (Housing) 2 and 3, the housing 30 is formed into a box shape as a whole. The housing 30 is made of, for example, metal. The housing 30 has a lower wall portion 32, an upper wall portion 34, a pair of side wall portions 36, and a rear wall portion 38. The lower wall portion 32 is placed on an upper surface 14U of the passenger compartment 14. The upper wall portion 34 is disposed above the lower wall portion 32 (in the direction of the arrow Z).

[0058] 2, the upper surface 34U of the upper wall portion 34 is a curved surface that curves downward toward the front (arrow X direction) when viewed from the width direction (arrow Y direction) of the housing 30. The upper wall portion 34 also functions as a wind guide plate (windshield, air deflector).

[0059] The pair of side walls 36 extend upward from both ends of the lower wall 32 in the width direction (arrow Y direction) and face each other in the width direction of the housing 30. Similarly to the upper surface 34U of the upper wall 34, the upper ends of the pair of side walls 36 are curved downward and forward when viewed from the width direction of the housing 30.

[0060] The upper end sides of the pair of side wall portions 36 are protruding portions 36A that protrude upward from the upper surface 34U of the upper wall portion 34. The pair of protruding portions 36A extend from the front end side to the rear end side of the upper surface 34U of the housing 30. The pair of protruding portions 36A suppresses the generation of a vortex that turns around the upper surface 34U side of the housing 30 as indicated by the arrow V in the traveling wind W that flows along the side surface (outer surface) 36S of the side wall portion 36 of the housing 30 when the freight vehicle 10 is traveling.

[0061] The rear ends of the pair of side wall portions 36 are connected by a rear wall portion 38. The rear wall portion 38 extends upward from the rear end of the lower wall portion 32.

[0062] (Containment Cell) As shown in Fig. 4, the housing 30 has an accommodation chamber 40, an air intake passage 42, an air intake port 44, an exhaust passage 46, and an exhaust port 48. The accommodation chamber 40 is disposed in the middle of the housing 30 in the front-rear direction. The accommodation chamber 40 also spans a pair of side wall portions 36. The accommodation chamber 40 is divided into a plurality of separate accommodation chambers 40E by partition wall portions 50 (see Fig. 5), which will be described later. Each separate accommodation chamber 40E accommodates a wind turbine 70.

[0063] The accommodation chamber 40 is formed in a circular shape when viewed from the width direction of the housing 30. Specifically, a ceiling surface 40A of the accommodation chamber 40 is a curved surface that is curved in an arc shape. In addition, a floor surface 40B of the accommodation chamber 40 is a curved surface that is curved upward toward the rear. The floor surface 40B of the accommodation chamber 40 is continuous with floor surfaces 42B, 46B of the intake air flow path 42 and the exhaust air flow path 46, which will be described later.

[0064] When the freight vehicle 10 is traveling, a traveling wind W is supplied to the accommodation chamber 40 from the air intake port 44 through the air intake passage 42. In addition, the traveling wind W supplied to the accommodation chamber 40 is exhausted from the exhaust port 48 via the exhaust passage 46.

[0065] (air supply port) The air intake port 44 is formed on the front end side (lower end side) of the curved upper wall portion 34 (upper surface 34U) so as to face forward. The air intake port 44 is disposed at the lower part of the front end side of the housing 30, and is located in front of the storage chamber 40. The air intake port 44 extends across a pair of side wall portions 36 of the housing 30. The air intake port 44 is connected to the lower part of the front side of the storage chamber 40 via an air intake flow path 42.

[0066] (Air supply flow path) The air intake passage 42 is disposed in front of the accommodation chamber 40. The rear end of the air intake passage 42 is connected to the front lower part of the accommodation chamber 40. The air intake passage 42 extends forward from the lower part of the accommodation chamber 40, and connects the accommodation chamber 40 to the air intake port 44. A ceiling surface 42A and a floor surface 42B of the air intake passage 42 are aligned in the front-rear direction. The air intake passage 42 also spans a pair of side walls 36 of the housing 30.

[0067] (Exhaust port) The exhaust port 48 is formed facing upward on the rear end side (upper end side) of the curved upper wall portion 34 (upper surface 34U). The exhaust port 48 reaches the rear wall portion 38 of the housing 30. In other words, the upper end portion of the rear wall portion 38 forms a rear edge portion 48R of the exhaust port 48.

[0068] In this embodiment, the rear edge 48R of the exhaust port 48 is positioned at approximately the same height as the front edge 48F of the exhaust port 48. However, the position of the rear edge 48R of the exhaust port 48 may be lower or higher than the front edge 48F of the exhaust port 48.

[0069] The exhaust port 48 is disposed on the upper end side of the rear part of the housing 30, and is located rearward of the accommodation chamber 40 and above the air supply port 44. The exhaust port 48 also spans the pair of side walls 36 of the housing 30. The exhaust port 48 is connected to the rear lower part of the accommodation chamber 40 via an exhaust flow path 46.

[0070] (Exhaust flow path) The exhaust flow path 46 is disposed at the rear of the accommodation chamber 40. The front end of the exhaust flow path 46 is connected to the rear lower portion of the accommodation chamber 40. The exhaust flow path 46 curves upward from the accommodation chamber 40 toward the rear, and connects the accommodation chamber 40 to the exhaust port 48. The ceiling surface 46A and the floor surface 46B of the exhaust flow path 46 are curved surfaces that curve upward toward the rear. The exhaust flow path 46 spans a pair of side wall portions 36 of the housing 30.

[0071] (Partition wall) 5, the storage chamber 40 is provided with a partition wall portion 50. The partition wall portion 50 is disposed along the front-rear direction. The partition wall portion 50 divides the storage chamber 40 in the width direction of the housing 30 into a plurality of divided storage chambers 40E (two in this embodiment).

[0072] Each of the multiple divided storage chambers 40E accommodates a wind turbine 70, which will be described later. The front end side of the partition wall portion 50 is a front tapered portion 50F that tapers forward in a plan cross-sectional view. As a result, when the freight vehicle 10 is traveling, the traveling wind W supplied to the partition wall portion 50 from the air intake passage 42 is guided by the front tapered portion 50F to the wind turbines 70 accommodated in the divided storage chambers 40E on both sides of the partition wall portion 50, as shown by arrow a1.

[0073] Further, an air intake guide portion 52 is provided on each of the pair of side wall portions 36 of the housing 30. Each air intake guide portion 52 is disposed in the air intake flow path 42 in front of the accommodation chamber 40. Each air intake guide portion 52 is formed in a plate shape and is inclined toward the inside (center) in the width direction of the housing 30 toward the rear in a plan cross-sectional view.

[0074] As a result, when the freight vehicle 10 is traveling, the traveling wind W flowing along the side wall portion 36 of the air intake passage 42 into the storage chamber 40 is guided by the air intake guide portion 52 to the wind turbine 70 accommodated in the divided storage chamber 40E, as shown by arrow a2. Note that the air intake guide portion 52 may be omitted.

[0075] The rear end side of the partition wall 50 is a rear tapered portion 50R that tapers toward the rear in a planar cross section. In addition, the side wall portions 36 on both sides of the housing 30 are inclined toward the rear at a predetermined angle θ toward the outside in the width direction of the housing 30 (toward the arrow Y side) with respect to the front-rear direction of the housing 30 in a planar cross section. This causes the cross-sectional areas of the intake air flow path 42, the storage chamber 40, and the exhaust air flow path 46 to increase toward the rear. Therefore, when the freight vehicle 10 is traveling, the traveling wind W easily passes through (escapes) the intake air flow path 42, the storage chamber 40, and the exhaust air flow path 46.

[0076] A generator 60 is housed inside the partition wall 50. Rotating shafts 72 of a pair of wind turbines 70 are connected to the generator 60. The generator 60 generates electricity as the pair of wind turbines 70 rotate. In other words, the generator 60 converts the rotational energy of the pair of wind turbines 70 into electrical energy. A battery (not shown) or the like that stores the electricity generated by the generator 60 is connected to the generator 60.

[0077] The housing 30 may be provided with a plurality of partition wall portions 50. Also, the partition wall portion 50 may be omitted. Also, the generator 60 is not limited to being housed inside the partition wall portion 50, and may be housed in another portion of the housing 30, or may be installed in the car body 12 of the freight vehicle 10, for example.

[0078] (Wind Turbines) The wind turbine 70 is a windmill that rotates about a rotation shaft 72 that is aligned in the width direction of the housing 30. The wind turbine 70 has the rotation shaft 72, a pair of side bases 74, and a plurality of rotor blades 76. The pair of side bases 74 face each other in the width direction of the housing 30.

[0079] 4, each side base 74 has 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 in the width direction of the housing 30. When viewed in the width direction of the housing 30, the plurality of support arm portions 74B extend radially outward from the outer periphery of the central portion 74A with the rotation shaft 72 as the center. A rotor 76 is bridged across each of the support arm portions 74B of the pair of side bases 74.

[0080] The multiple rotors 76 rotate around the rotary shaft 72 by receiving the traveling wind W supplied from the air intake port 44 through the air intake passage 42. 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 below the rotary shaft 72 and heads toward the rear of the rotary shaft 72.

[0081] 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.

[0082] 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.

[0083] A plurality of recesses 78 that receive the traveling wind W supplied from the air intake passage 42 are formed on the outer surface 76S1 of each rotor 76. These recesses 78 make it easier for the rotor 76 to rotate in the arrow P direction.

[0084] The number and arrangement of the recesses 78 can be changed as appropriate. The recesses 78 may be omitted. The number, arrangement, shape, etc. of the rotors 76 can be changed as appropriate.

[0085] (straightening blade) The housing 30 is provided with a straightening wing 80. The straightening wing 80 is a wing that improves the exhaust efficiency from the exhaust port 48 by straightening the running wind W that flows upward (upward and rearward) along the upper surface 34U of the housing 30 and passes above the exhaust port 48 when the freight vehicle 10 is traveling.

[0086] The airflow control wing 80 is disposed above the exhaust port 48, and covers the front side of the exhaust port 48 from above. The airflow control wing 80 is bridged across the protruding portions 36A of the side wall portions 36 on both sides of the housing 30. The upper ends of the protruding portions 36A of the side wall portions 36 protrude upward beyond the upper surface 80U of the airflow control wing 80. The range over which the airflow control wing 80 covers the exhaust port 48 from above can be changed as appropriate.

[0087] The front end 80F of the airflow wing 80 is located above the upper surface 34U of the housing 30. As a result, when the freight vehicle 10 is traveling, the traveling wind W that flows obliquely upward (upward and rearward) along the upper surface 34U of the housing 30 passes above and below the airflow wing 80.

[0088] The front end portion 80F of the airflow wing 80 is located forward of the leading edge portion 48F of the exhaust port 48. This prevents the traveling wind W discharged from the exhaust port 48 from flowing around the front end portion 80F of the airflow wing 80 to the upper surface 80U side of the airflow wing 80.

[0089] The airflow wing 80 is curved downwardly convexly when viewed from the width direction of the housing 30. Specifically, the upper surface 80U and the lower surface 80L of the airflow wing 80 are curved surfaces that are curved downwardly convexly. As a result, when the freight vehicle 10 is traveling, the traveling wind W passing under the airflow wing 80 flows along the lower surface 80L of the airflow wing 80 due to the Coanda effect, and heads obliquely upward from the rear end portion 80R of the airflow wing 80. Furthermore, the rear end portion 80R of the airflow wing 80 is located above the front end portion 80F of the airflow wing 80. As a result, the traveling wind W passing under the airflow wing 80 is easily directed obliquely upward from the rear end portion 80R of the airflow wing 80.

[0090] The position of the rear end 80R of the airflow straightening vane 80 is not limited to being above the front end 80F of the airflow straightening vane 80, and may be at the same height as the front end 80F of the airflow straightening vane 80, for example.

[0091] (Opening and closing plate) An opening / closing plate 90 is provided in the housing 30. The opening / closing plate 90 is formed in a plate shape capable of opening and closing the air intake port 44, and is disposed within the air intake flow path 42 of the housing 30. A lower end of the opening / closing plate 90 is rotatably supported by the housing 30 via a rotating shaft 92. The rotating shaft 92 is disposed along the width direction of the housing 30, and is supported by the side wall portions 36 on both sides of the housing 30.

[0092] The opening / closing plate 90 is capable of transitioning between a closed state in which the air supply port 44 is closed, as indicated by a two-dot chain line, and an open state in which the opening / closing plate 90 rotates from the closed state to the accommodation chamber 40 side about a rotation shaft 92, as indicated by a solid line, to open the air supply port 44. In the open state, the opening / closing plate 90 is inclined with respect to the floor surface 40B of the air supply flow path 42.

[0093] More specifically, when the opening / closing plate 90 is viewed in the open state from the width direction of the housing 30, the opening / closing plate 90 is inclined upward and rearward with respect to the floor surface 40B of the air intake passage 42. As a result, the running wind W supplied to the air intake passage 42 from the air intake port 44 flows obliquely upward (upward and rearward) along the upper surface 90U of the opening / closing plate 90 in the open state, as shown by arrow a3. Note that the opening / closing plate 90 may be omitted.

[0094] (action) Next, the operation of this embodiment will be described.

[0095] (straightening blade) First, the operation of the wind power generating device 20 for vehicles will be described, along with the function of the airflow straightening vanes.

[0096] 4 shows the wind power generator 20 for vehicles installed on the upper surface 14U (see FIG. 1) of the passenger compartment 14 of the freight vehicle 10. The wind power generator 20 for vehicles is installed with the air intake port 44 facing forward. The opening / closing plate 90 of the wind power generator 20 for vehicles is in the open state.

[0097] When the freight vehicle 10 travels (forward) in this state, a negative pressure is generated in the exhaust flow path 46 by the traveling wind W flowing above the exhaust port 48, and the air in the accommodation chamber 40 is exhausted obliquely upward (upward and rearward) from the exhaust port 48 through the exhaust flow path 46. As a result, the traveling wind W is taken into the accommodation chamber 40 through the air intake port 44 and the air intake flow path 42. At this time, the multiple rotors 76 of the wind turbine 70 receive the traveling wind W and rotate in the direction of arrow P around the rotation shaft 72. As these rotors 76 rotate, the generator 60 generates electricity. The electricity generated by the generator 60 is supplied to, for example, a battery (not shown).

[0098] In addition, when the freight vehicle 10 travels, the traveling wind W flows obliquely upward along the upper surface 34U of the casing 30, and passes above and below the airflow wing 80. Here, the airflow wing 80 is curved in a downward convex shape when viewed from the width direction of the casing 30.

[0099] As a result, the traveling wind W passing under the airflow wing 80 flows along the lower surface 80L of the curved airflow wing 80 due to the Coanda effect, and flows obliquely upward from the rear end portion 80R of the airflow wing 80. As a result, the lower surface side of the airflow wing 80, i.e., the vicinity of the exhaust port 48, becomes negative pressure, and the traveling wind W in the accommodation chamber 40 and the exhaust flow path 46 is pulled backward.

[0100] This improves the exhaust efficiency of the traveling wind W exhausted from the exhaust port 48. As a result, this also improves the supply efficiency of the traveling wind W supplied to the accommodation chamber 40 from the intake port 44. This improves the rotation efficiency of the wind turbine 70, thereby improving the power generation efficiency.

[0101] In addition, the rear end 80R of the airflow wing 80 is located higher than the front end 80F of the airflow wing 80. This makes it easier for the traveling wind W passing under the airflow wing 80 to flow obliquely upward from the rear end 80R of the airflow wing 80 when the freight vehicle 10 is traveling. This further improves the exhaust efficiency from the exhaust port 48.

[0102] Furthermore, the front end 80F of the airflow straightening wing 80 is located forward of the front edge 48F of the exhaust port 48 and above the upper surface 34U of the housing 30. This prevents the traveling wind W discharged from the exhaust port 48 from passing over the front end 80F of the airflow straightening wing 80 and going around to the upper surface 80U side of the airflow straightening wing 80. Therefore, the exhaust efficiency of the traveling wind W discharged from the exhaust port 48 is further improved.

[0103] In addition, the airflow straightening vanes 80 cover the exhaust port 48 from above. This prevents, for example, rain or snow from entering the accommodation chamber 40 through the exhaust port 48. Furthermore, even if the wind turbine 70 becomes detached from the housing 30 while the freight vehicle 10 is traveling, the wind turbine 70 interferes with the airflow straightening vanes 80, preventing the wind turbine 70 from falling.

[0104] In addition, the upper surface 34U of the housing 30 is curved downward toward the front. As a result, when the freight vehicle 10 travels, the traveling wind flows obliquely upward along the upper surface 34U of the housing 30. Therefore, the air resistance of the housing 30 is reduced.

[0105] Furthermore, the traveling wind W that flows obliquely upward along the upper surface 34U of the housing 30 passes above and below the air straightening wing 80. That is, the traveling wind W that flows along the upper surface 34U of the housing 30 is collected by the air straightening wing 80. This increases the amount of traveling wind W passing above and below the air straightening wing 80, so that, as described above, the traveling wind W in the accommodation chamber 40 is more likely to be pulled obliquely upward from the exhaust port 48. Therefore, the exhaust efficiency from the exhaust port 48 is further improved, and the intake efficiency from the intake port 44 is further improved.

[0106] As shown in FIG. 2, the side walls 36 on both sides of the housing 30 each have a protrusion 36A that protrudes upward beyond the upper surface 34U of the housing 30.

[0107] Here, when the freight vehicle 10 travels, the flow speed of the traveling wind W flowing diagonally upward along the upper surface 34U of the housing 30 becomes faster than the flow speed of the traveling wind W flowing backward along the side surface 36S of the housing 30, and the air pressure on the upper surface 34U side of the housing 30 becomes lower than the air pressure on the side surface side of the housing 30. As a result, a vortex is generated that wraps around from the side surface 36S side of the housing 30 to the upper surface 32U side, which may increase air resistance.

[0108] In contrast, in this embodiment, as described above, the side wall 36 of the housing 30 has a protruding portion 36A that protrudes upward from the upper surface 34U of the housing 30. This protruding portion 36A prevents air from flowing from the side surface 36S of the housing 30 to the upper surface 32U, as shown by the arrow V. As a result, the generation of vortexes that flow from the side surface 36S of the housing 30 to the upper surface 32U is suppressed, thereby reducing the air resistance of the housing 30.

[0109] Furthermore, the protrusion 36A extends from the front end side to the rear end side of the upper surface 34U of the housing 30. This suppresses the generation of vortexes that wrap around from the side surface 36S side of the housing 30 to the upper surface 32U side from the front end side to the rear end side of the upper surface 34U of the housing 30 when the freight vehicle 10 is traveling. This further reduces the air resistance of the housing 30.

[0110] The airflow wing 80 is bridged over the protruding portions 36A on both sides. The airflow wing 80 increases the rigidity of the protruding portions 36A, suppressing vibration of the protruding portions 36A caused by the running of the freight car 10. The protruding portions 36A also suppress the generation of wingtip vortices at the ends of the airflow wing 80.

[0111] (Containment Cell) Next, the function of the storage chamber 40 will be described.

[0112] 5, a partition wall portion 50 is provided in the accommodation chamber 40 of the housing 30. The partition wall portion 50 divides the accommodation chamber 40 in the width direction of the housing 30 into a plurality of divided accommodation chambers 40E. Each of these divided accommodation chambers 40E accommodates a wind turbine 70.

[0113] The front end side of the partition wall portion 50 is a front tapered portion 50F that tapers forward in a planar cross-sectional view. As a result, when the freight vehicle 10 is traveling, the traveling wind W supplied to the accommodation chamber 40 is guided by the front tapered portions 50F of the partition wall portion 50 to the wind turbines 70 accommodated in the divided accommodation chambers 40E on both sides of the partition wall portion 50, as shown by arrow a1. This increases the rotation efficiency of the wind turbines 70.

[0114] Further, air supply guide portions 52 are provided on the side walls 36 on both sides of the housing 30. The air supply guide portions are located forward of the accommodation chamber 40, and are inclined inward in the width direction of the housing 30 toward the rear in a plan cross-sectional view.

[0115] As a result, when the freight vehicle 10 is traveling, the traveling wind W supplied from the air intake port along both side walls of the housing 30 to the accommodation chamber 40 is guided by the air intake guide parts to the inside in the width direction of the housing 30, i.e., to the wind turbine 70 accommodated in the accommodation chamber 40, as shown by arrow a2. This further increases the rotation efficiency of the wind turbine 70.

[0116] Next, the rear end side of the partition wall portion 50 is formed as a rear tapered portion 50R that tapers toward the rear in a plan cross-sectional view. This makes it easier for the traveling wind W to flow from the divided accommodation chambers 40E on both sides of the partition wall portion 50 toward the exhaust port 48 while the freight vehicle 10 is traveling. This further increases the rotation efficiency of the wind turbine 70.

[0117] In addition, the side walls 36 on both sides of the storage chamber 40 are inclined at a predetermined angle θ toward the rear and outward in the width direction of the housing 30 in the front-rear direction in a planar cross-sectional view. This makes it easier for the running wind W to flow from the storage chamber 40 toward the exhaust port 48 when the freight vehicle 10 is running. This further increases the rotation efficiency of the wind turbine 70.

[0118] Furthermore, a generator 60 that generates power in accordance with the rotation of the wind turbine 70 is provided inside the partition wall 50. By accommodating the generator 60 inside the partition wall 50 in this manner, the size of the housing 30 can be reduced.

[0119] (Opening and closing plate) Next, the function of the opening and closing plate 90 will be described.

[0120] 4, the housing 30 is provided with an opening / closing plate 90 that opens and closes the air intake port 44. The opening / closing plate 90 has a lower end portion supported by the housing 30 so as to be rotatable about a rotation shaft 92 that extends in the width direction of the housing 30. This opening / closing plate 90 is inclined with respect to the floor surface 42B of the air intake flow path 42 when in an open state in which the opening / closing plate 90 is rotated toward the accommodation chamber 40 to open the air intake port 44.

[0121] Here, when the freight vehicle 10 is traveling, if the traveling wind W flows along the floor surface 40B of the air intake passage 42, air resistance increases due to friction with the floor surface 40B and the like.

[0122] In contrast, in this embodiment, as described above, the opening / closing plate 90 is inclined with respect to the floor surface 40B of the air intake passage 42 in the open state. As a result, when the freight vehicle 10 is traveling, the traveling wind W supplied to the air intake passage 42 flows obliquely upward along the opening / closing plate 90 as shown by arrow a3, and moves upward away from the floor surface of the air intake passage 42. Therefore, air resistance such as friction generated between the traveling wind W and the floor surface 40B is reduced.

[0123] Furthermore, in the closed state where the air intake port 44 is closed by the opening / closing plate 90, snow, foreign objects, etc. are prevented from entering the accommodation chamber 40 through the air intake port 44. Therefore, damage to the wind turbine 70, etc. is prevented.

[0124] (Modification) Next, a modification of the above embodiment will be described.

[0125] 6, an angle adjustment mechanism 100 that adjusts the rotation angle of the airflow control vanes 80 is provided on the housing 30. The angle adjustment mechanism 100 has a rotation shaft 102 and a fixing device (not shown).

[0126] The rotating shaft 102 is provided integrally with the front end portion 80F of the airflow straightening wing 80. This rotating shaft 102 is disposed along the width direction of the housing 30, and is rotatably supported by the protruding portions 36A on both sides of the housing 30. This allows the airflow straightening wing 80 to rotate about the rotating shaft 102.

[0127] Both ends of the rotating shaft 102 pass through through holes (not shown) formed in the protruding portions 36A on both sides of the housing 30. Both ends of the rotating shaft 102 are provided with male threads (not shown). A pair of nuts is attached to each male thread. The pair of nuts clamps the protruding portion 36A from both sides, thereby restricting the rotation of the rotating shaft 102 relative to the protruding portion 36A, and the air straightening vane 80 is held at a predetermined rotation angle.

[0128] Here, for example, depending on the type of cargo vehicle 10, the height of the upper surface 16U of the luggage compartment 16 may differ. In such a case, in this modification, for example, the rotation angle of the air flow straightening wing 80 is adjusted by the angle adjustment mechanism 100 so that the rear end portion 80R of the air flow straightening wing 80 is at the same height as the upper surface 16U of the luggage compartment 16 of the cargo vehicle 10. This makes it possible to reduce the air resistance of the front surface 16F of the luggage compartment 16. Therefore, the versatility of the vehicle wind power generation device 20 is improved.

[0129] 7 and 8, the wind power generating device 20 for vehicles includes an outdoor unit 110 for air conditioning. As shown in Fig. 7, the outdoor unit 110 is connected to an indoor unit 112 arranged in the passenger compartment 14, for example, and configures a refrigeration cycle (cooling cycle) together with the indoor unit 112.

[0130] A control unit 114 (see FIG. 8) is connected to the outdoor unit 110 and the indoor unit 112. The control unit 114 controls the operations of the outdoor unit 110 and the indoor unit 112. A battery 116 provided in the body 12 of the cargo vehicle 10, for example, is connected to the outdoor unit 110, the indoor unit 112, and the control unit 114.

[0131] The outdoor unit 110 is disposed on an upper surface 14U of the passenger compartment 14 and at the rear side of the housing 30. Specifically, the housing 30 has an equipment room 120. The equipment room 120 is disposed at the rear of the accommodation chamber 40 and below the exhaust flow path 46. The equipment room 120 is defined by a bottom wall portion 32, a pair of side wall portions 36, and a rear wall portion 38 of the housing 30.

[0132] The pair of side walls 36 in the equipment room 120 are formed with an air supply port 124 that takes in air (outside air) into the equipment room 120. Also, the rear wall 38 in the equipment room 120 is formed with an opening 122. The outdoor unit 110 is disposed in this opening 122.

[0133] The outdoor unit 110 is attached to a stay 18 attached to the outer surface of the rear wall of the passenger compartment 14. This prevents the load of the outdoor unit 110 from acting on the upper surface 14U of the passenger compartment 14, or reduces the load of the outdoor unit 110 acting on the upper surface 14U of the passenger compartment 14.

[0134] The outdoor unit 110 is disposed with the air outlet 110A facing rearward and facing the front surface 16F of the luggage compartment 16. The air outlet 110A of the outdoor unit 110 is disposed outside the equipment room 120. On the other hand, the air inlet 110B of the outdoor unit 110 is disposed inside the equipment room 120.

[0135] By installing the outdoor unit 110 in the equipment room 120 utilizing the space below the exhaust flow path 46 in this manner, the vehicle wind power generation device 20 can be made smaller in size.

[0136] Furthermore, by supporting the outdoor unit 110 by the stays 18 attached to the outer surface of the rear wall portion of the passenger compartment 14, the load on the upper surface 14U of the passenger compartment 14 can be reduced.

[0137] Although one embodiment of the present disclosure has been described above, the present disclosure 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 disclosure in various forms without departing from the gist of the present disclosure.
