  However, in the above-described conventional example, the wind turbine is not arranged in consideration of the layout of the vehicle component parts. When such a layout is taken into consideration, depending on the arrangement position of the wind turbine, the wind turbine may be connected to the heat exchanger. There is a possibility of impeding the supply of traveling wind or affecting the shock absorption performance at the time of vehicle collision.

  The present invention has been made in view of such points, and an object of the present invention is to provide a windmill by devising an arrangement of the windmill when an in-vehicle wind power generator including the windmill is mounted on the vehicle. However, there is an attempt to suppress the supply of vehicle travel wind to the heat exchanger or the impact absorption performance at the time of a vehicle collision.

  In order to achieve the above object, according to the present invention, the wind turbine is arranged on the outer side in the vehicle width direction than the front side frame in the front portion of the vehicle.

  Specifically, in the first aspect of the invention, the vehicle is mounted on a vehicle including a pair of left and right front side frames and a heat exchanger disposed between the front side frames, and is rotated by the vehicle traveling wind. An in-vehicle wind power generator including a windmill and a generator driven by the rotation of the windmill is an object.

  And the said windmill shall be arrange | positioned in the vehicle width direction outer side rather than the said front side frame in the said vehicle front part.

  With the above configuration, the wind turbine is disposed on the side opposite to the side on which the heat exchanger (shroud) is disposed with respect to the front side frame, so that the supply of vehicle running wind to the heat exchanger is obstructed. Therefore, it is possible to appropriately perform heat exchange in the heat exchanger. In addition, in the case of a light vehicle collision, the windmill will not contact the heat exchanger and damage the heat exchanger. In the case of a heavy collision, the windmill will not cause the dash panel to move backward. Shock absorption performance equivalent to that of vehicles not equipped with can be obtained.

  According to a second aspect of the present invention, in the first aspect of the invention, the vehicle includes a bumper reinforcement that is coupled to the two front side frames and extends in the vehicle width direction in front of the heat exchanger. It is assumed that the vehicle is disposed behind the bumper reinforcement and in front of the front wheels of the vehicle.

  As a result, since there is a relatively large empty space at the rear of the vehicle and in front of the front wheels relative to the bumper reinforcement at the side of the vehicle, the space can be used effectively. Further, it is possible to sufficiently supply the vehicle traveling wind to the blades of the windmill.

  According to a third aspect of the invention, in the first or second aspect of the invention, the vehicle includes a bumper fascia, the bumper fascia being provided at a substantially central portion in the vehicle width direction of the bumper fascia and A central wind guide opening for guiding the heat exchanger, and an outer wind guide opening provided outside the central wind guide opening in the vehicle width direction and for guiding the vehicle traveling wind to the wind turbine. It shall be.

  By doing so, it is possible to reliably supply the vehicle traveling wind to the heat exchanger or the like and also to reliably supply the vehicle traveling wind to the blades of the windmill.

  According to a fourth aspect of the present invention, in the third aspect of the present invention, the bumper fascia has a curved shape such that a central portion in the vehicle width direction projects in front of the vehicle with respect to both ends in a plan view. A duct for setting the outer wind guide opening as an inlet for vehicle running wind and an opening provided in front of the front wheel on the side surface of the vehicle as an outlet for the vehicle running wind introduced from the inlet; The said windmill shall be accommodated in the said duct.

  As described above, when the bumper fascia has a curved shape such that the center in the vehicle width direction projects in front of the vehicle with respect to both ends in plan view, the wind speed is considerably high at the front portion of the front wheel on the side surface of the vehicle. Negative pressure is generated. As a result, by providing the duct outlet at the front portion of the front wheel on the side surface of the vehicle, the flow velocity in the duct can be increased by the suction effect, and the inflow and outflow of the vehicle running wind into the duct can be made smooth. it can. Therefore, high power generation performance can be obtained even when the vehicle is traveling at a low speed.

  According to a fifth aspect of the present invention, in the fourth aspect of the present invention, the portion between the introduction port and the windmill in the duct is provided with closing means capable of switching the portion to be closed and openable. To do.

  That is, for example, when the electrical load of the generator is lost, the rotational speed of the generator becomes too high, increasing the mechanical burden on the wind turbine and the generator, or generating a high voltage in the case of a DC generator. May damage other electrical equipment. However, in the present invention, the supply of the vehicle traveling wind to the blades of the windmill can be shut off by closing the outer air guide opening by the closing means, and as a result, the generator can be prevented from over-rotating. It is possible to prevent damage to wind turbines, generators, electrical equipment, and the like.

  According to a sixth aspect of the present invention, in the invention according to any one of the first to fifth aspects, the generator is supported by the front side frame via a bracket.

  As a result, the generator, which is a heavy object, can be reliably and firmly supported, and the generator can be disposed in the vicinity of the windmill, and the rotation of the rotating shaft of the windmill can be easily transmitted to the generator. be able to.

  As described above, according to the in-vehicle wind power generator of the present invention, the wind turbine is disposed on the outer side in the vehicle width direction from the front side frame at the front portion of the vehicle, thereby sufficiently supplying the vehicle wind to the heat exchanger. In addition, it is possible to appropriately perform heat exchange in the heat exchanger, and it is possible to prevent the windmill from affecting the impact absorption performance at the time of the vehicle collision. High safety performance can be maintained even with the.

  Outer wind guide openings 9c and 9c are provided on the outer side in the vehicle width direction of the lower wind guide opening 9a in the lower part of the bumper fascia 9 (portions corresponding to the left and right sides of the front surface of the vehicle). Further, side opening portions 9d and 9d are respectively provided at the left and right end portions of the bumper fascia 9 (the portion corresponding to the front of the front wheel on the side surface portion of the vehicle) (in FIG. 1, the one on the right side of the vehicle). Is not visible).

  The vehicle is equipped with an in-vehicle wind power generator, and the in-vehicle wind power generator is driven by two propeller-type wind turbines 31 and 31 that are rotated by the vehicle traveling wind and the rotation of each wind turbine 31. And a battery 32 (not shown) mounted on the vehicle by the operation of the generator 32.

  The two windmills 31 are respectively disposed on the left and right sides of the front portion of the vehicle such that the rotation shaft 31a of the windmill 31 extends in the vehicle front-rear direction. Specifically, the wind turbine 31 on the left side of the vehicle is on the vehicle width direction outer side (vehicle left side) than the front side frame 1 on the left side of the vehicle in the front part of the vehicle, behind the bumper reinforcement 6 and on the left side of the vehicle. It is disposed in front of the front wheel. Further, the wind turbine 31 on the right side of the vehicle is on the vehicle width direction outer side (the vehicle right side) than the front side frame 1 on the right side of the vehicle in the front part of the vehicle, behind the bumper reinforcement 6 and in front of the front wheel on the right side of the vehicle. Arranged in position.

  Ducts 35 and 35 are respectively provided on both left and right side portions (outer in the vehicle width direction than the front side frame 1) in the front portion of the vehicle, and the windmills 31 are accommodated in the ducts 31, respectively. . Each of the ducts 35 serves as an inlet for the vehicle running wind, and the side opening 9d serves as an outlet for the vehicle running wind introduced from the inlet.

  The generator 32 is arranged on the rear side of each windmill 31. As shown in an enlarged view in FIG. 4, each of the generators 32 is supported by the front side frame 1 via two brackets 37 and 37 that are arranged apart from each other in the vehicle front-rear direction. Each duct 35 is provided with one through hole 35a through which the two brackets 37.37 pass, and a portion between the brackets 37.37 in the through hole 35a is a lid member (not shown). It is supposed to be blocked.

  The rotating shafts 31a of the wind turbines 31 also serve as the rotating shafts of the generators 32, whereby the wind turbines 31 are supported by the generators 32 (and thus the front side frame 1). Become. A hub 31c having three blades 31b, 31b,... Attached to the outer peripheral surface thereof at substantially equal intervals in the circumferential direction at the front end portion of the rotating shaft 31a of each wind turbine 31 rotates integrally with the rotating shaft 31a. To be fixed.

  As shown in FIG. 3, each windmill 31 has a rotational space (more precisely, a part of the rotational space) of the blade 31b of the windmill 31 overlapping with each outer air guide opening 9c when viewed from the front of the vehicle. It is arranged like this. That is, in the vehicle front view, the inner portion of the rotation locus circle C at the outer peripheral tip of the blade 31b is a rotation space of the blade 31b, and the lower portion of the rotation space from the rotation shaft 31a overlaps with the outer air guide opening 9c. is doing.

  In the present embodiment, the generator 32 is a DC generator. Since the generated voltage pulsates, the generator 32 is converted into a constant DC voltage by the AC / DC converter, and further, a predetermined voltage is generated by the DC / DC converter. The battery is charged after being converted to voltage.

  In each duct 35, a portion between the introduction port (outside air guide opening 9c) and the wind turbine 31 is provided with closing means 39 that can switch the portion to be closed and open (FIG. 2). And FIG. 4). As shown in FIG. 4, the closing means 39 is attached to a rotating shaft 40 extending in the vehicle width direction, a wind shielding plate 41 having a base end fixed to the rotating shaft 40, and an upper wall surface of the duct 35. The support members 43 and 43 that are fixed and rotatably support both ends of the rotation shaft 40 and the one support member 43 (the support member 43 outside the vehicle in FIG. 4) are fixedly mounted and rotated. The motor 44 is configured to rotate the shaft 40 in both forward and reverse directions.

  A helical gear 45 is attached and fixed to an end portion (vehicle outer end portion) of the rotating shaft 40 on which the motor 44 is disposed, and the helical gear 45 is attached to a rotating shaft of the motor 44. A worm gear 46 that meshes with 45 is attached and fixed. With this, the windshield plate 41 can be rotated together with the rotation shaft 40 by the motor 44. The wind shield plate 41 has a state in which the tip end portion is positioned substantially directly below the base end portion and extends in a substantially vertical direction by the motor 44 (a state indicated by a solid line in FIGS. 2 and 4), and the tip end. The part is switched to a state (a state indicated by a two-dot chain line in FIGS. 2 and 4) located in front of the vehicle with respect to the base end part and substantially along the upper wall surface of the duct 35. The wind shield plate 41 is in a state of extending in a substantially vertical direction by abutting against a stopper 47 fixed to the support member 43 on the side opposite to the motor 44 (center side in the vehicle width direction), and the tip portion is By abutting on the upper wall surface of the duct 35, the state substantially follows the upper wall surface of the duct 35.

  When the wind shield plate 41 extends in a substantially vertical direction, the wind shield plate 41 closes a portion between the outer wind guide opening 9c and the wind turbine 31 to the blade 31b of the wind turbine 31. However, when the windshield 31 is in a state substantially along the upper wall surface of the duct 35, the vehicle running wind is supplied to the blades 31b of the windmill 31. Is made.

  The vehicle running wind is not supplied to the windmill 31 in this way, for example, when the electrical load on the generator 32 is lost (when the battery is fully charged). When the electrical load on the generator 32 is lost, the rotational speed of the generator 32 becomes too high, increasing the mechanical burden on the windmill 31 and the generator 32, or generating high voltage and damaging other electrical equipment. Since the closing means 39 is in the closed state, the generator 32 can be prevented from over-rotating, and damage to the windmill 31, the generator 32, and the electrical equipment can be prevented. be able to.

  Therefore, in the present embodiment, the windmill 31 and the generator 32 are disposed outside the front side frame 1 in the vehicle front direction in the vehicle width direction, behind the bumper reinforcement 6 and in front of the front wheels. Therefore, the windmill 31 and the generator 32 are not positioned in front of the shroud 10 and the supply of vehicle travel wind to the condenser 11 and the radiator 12 is not hindered. As a result, heat exchange between the capacitor 11 and the radiator 12 can be performed appropriately. Further, at the time of a light vehicle collision, the windmill 31 and the generator 32 do not come into contact with the capacitor 11 to damage the capacitor 11 and the radiator 12, and at the time of a heavy collision, the windmill 31 and the generator 32 move backward from the dash panel. Therefore, the impact absorbing performance equivalent to that of a vehicle not equipped with the on-vehicle wind power generator can be obtained.

  Further, since the outer wind guide opening 9c for guiding the vehicle running wind to the wind turbine 31 is provided separately from the lower and upper wind guiding openings 9a and 9b for guiding the wind to the condenser 11 and the radiator 12, the vehicle running Wind can be supplied to the condenser 11 and the radiator 12 more reliably, and can also be reliably supplied to the wind turbine 31. Moreover, since the wind turbine 31 is accommodated in the duct 35 and the discharge port of the duct 35 is a side opening 9d provided in the front portion of the front wheel on the side surface of the vehicle, the flow velocity in the duct 35 is reduced by the suction effect. You can speed up. That is, when the bumper fascia 9 has a curved shape such that the center in the vehicle width direction protrudes forward of the vehicle with respect to both ends in plan view, the wind speed is considerably high at the front portion of the front wheel on the side surface of the vehicle. Since negative pressure is generated, the discharge speed of the vehicle traveling wind introduced from the introduction port (outside air guide opening 9c) can be increased. Therefore, high power generation performance can be obtained even when the vehicle is traveling at a low speed.

  In the above embodiment, the windmill 31 is accommodated in the duct 35. However, if the rotational space of the blade 31b of the windmill 31 overlaps with the outer wind guide opening 9c in the front view of the vehicle, the outer wind guide opening 9c. Since the vehicle traveling wind from 9c can be guided to the windmill 31, the duct 35 is not necessarily required. However, housing the windmill 31 in the duct 35 is advantageous in terms of arrangement because it is not necessary for the rotational space of the blade 31b of the windmill 31 to overlap the outer wind guide opening 9c in the front view of the vehicle. In addition, as described above, the suction effect is surely obtained, which is advantageous in improving the power generation performance.

  Further, the wind turbine 31 may be disposed anywhere outside the front side frame 1 in the vehicle width direction at the front portion of the vehicle. However, as in the above-described embodiment, the wind turbine 31 is located behind the bumper reinforcement 6 and the front wheel of the vehicle. The forward position is advantageous in terms of space, and can sufficiently supply the vehicle running wind to the blades 31b of the windmill 31.

  Furthermore, in the said embodiment, although the generator 32 was supported by the front side frame 1, the generator 32 does not necessarily need to be supported by the front side frame 1, and other members, such as the crash can 5 and a bumper reinforcement. You may make it support. However, the generator 32 is securely and firmly supported in the vicinity of the windmill 31 (the rotation of the rotating shaft 31a of the windmill 31 can be easily transmitted to the generator 32 if arranged near the windmill 31). Therefore, it is preferable to support the front side frame 1 as in the above embodiment.

  Further, the type of the windmill 31 is not limited to the propeller type, but other types may be used, but the propeller type windmill is excellent in terms of high power generation efficiency.
