  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a truck 2 as an example of a vehicle equipped with an in-vehicle wind power generator 1 according to the present invention, and FIGS. 2 and 3 show details of the in-vehicle wind power generator 1. The truck 2 is provided with a luggage compartment 4 that is taller than the driving cabin 3 behind the driving cabin 3, and the in-vehicle wind power generator 1 is mounted on the roof of the driving cabin 3.

  The in-vehicle wind power generator 1 includes a wind turbine 6 rotatably supported on a casing 5 having a lateral width close to the lateral width of the driving cabin 3 with the rotation axis p being laterally directed, and a generator coupled to one end of the wind turbine 6. 7 and is equipped with accommodation equipment.

  The wind turbine 6 is a cross-flow type in which a large number of wind receiving blades 8 that are concavely curved toward the upper side in the rotational direction are arranged at a constant pitch in the circumferential direction and configured in a cylindrical bowl shape. The rotating support shaft 9 is supported by the side plate 10 at both left and right ends, and the generator 7 is coaxially connected to one end of the rotating support shaft 9.

  An external air flow inlet 11 is opened in the front portion of the casing 5 in a horizontally long manner, and a lower air guide 12 and an upper air guide 13 are provided below and above the external air flow inlet 11. The back is narrowed up and down from the front end opening.

  The lower air guide 12 is formed so as to guide the airflow from the front upward and rearward so as to guide it in a substantially tangential direction with respect to the tip rotation locus of the wind receiving blade 8 in the wind turbine 6, and the upper air guide 13 Is formed so as to guide the airflow from the front downward and downward to join the airflow guided by the lower airflow guide 12 at the narrowed portion of the external airflow inlet 11.

  An external airflow outlet 14 is provided on the upper surface of the rear part of the casing 5, and the airflow that has passed through the windmill 6 is smoothly guided to the upper side of the luggage compartment 4.

  The in-vehicle wind power generator 1 according to the present invention is configured as described above, and when the truck 2 travels, the windmill 6 is rotated by the outside air that flows backward above the operation cabin 3, thereby generating the generator 7. Is driven to rotate to generate electricity, and the generated electricity is charged to the battery.

  At this time, since the air flow guided by the lower wind guide 12 is guided in a substantially tangential direction with respect to the tip rotation locus of the wind receiving blade 8 in the wind turbine 6, the flow pressure of the air current is efficiently converted into the rotation of the wind turbine 6.
