The control unit 29 is provided inside the instrument panel 11. The control unit 29 is electrically connected to the actuator 28. The control unit 29 controls driving of the actuator 28.

(Construction of center wrap and side flaps)
The center flap 31 is fixed to a rotating shaft 26 located at the center of the air outlet 35. The center flap 31 rotates together with the rotation shaft 26 when the rotation shaft 26 rotates.
The center flap 31 is a plate-shaped flap. The center flap 31 has a flat surface 31a and a flat surface 31b. Surface 31b is located on the opposite side of surface 31a.

The side flaps 32 are fixed to a rotating shaft 26 located on one side in the width direction of the center flap 31 (one side in the width direction of the vehicle 10). The side flaps 33 are fixed to a rotating shaft 26 located on the other side in the width direction of the center flap 31 (on the other side in the width direction of the vehicle 10).
That is, the center flap 31 and the side flaps 32, 33 are arranged at the same outlet 35.
The side flap 32 is a plate-shaped flap and has a flat surface 32a and a flat surface 32b. Surface 32b is a surface located on the opposite side of surface 32a.
The side flap 33 is a plate-shaped flap, and has a flat surface 33a and a flat surface 33b. Surface 33b is a surface located on the opposite side of surface 33a.

The first angle θ1 between the horizontal plane S perpendicular to the vertical direction and the surface 31a of the center flap 31 is smaller than the second angle θ2 between the horizontal plane S and the surfaces 32a and 33a of the side flaps 32 and 33. It is configured to be.
In the first embodiment, by making the first angle θ1 smaller than the second angle θ2, the opening ratio of the side flaps 32, 33 (the ratio of the air outlet 35 opened by the side flaps 32, 33) is reduced. The opening ratio of the center flap 31 (the ratio of the air outlet 35 opened by the center flap 31) is made larger.

(Regarding the first and second angles θ1 and θ2 when supplying temperature-controlled air to the front seats and rear seats)
Here, the first and second angles θ1 and θ2 when supplying temperature-controlled air to the front seat 13 and the rear seat 15 will be explained with reference to FIGS. 2 to 4.
In this case, the first angle θ1 is preferably set, for example, at an angle at which temperature-controlled air is supplied to the upper part of the center console.
Further, the second angle θ2 is preferably set, for example, at an angle at which temperature-controlled air is supplied to the upper part of the headrest of the front seat 13.
The postures of the center flap 31 and the side flaps 32 are maintained so as to satisfy the above two conditions (angles).

(Regarding the first and second angles θ1 and θ2 when supplying temperature-controlled air preferentially to the front seats)
Next, the first and second angles θ1 and θ2 when temperature-controlled air is preferentially supplied to the front seats 13 will be described with reference to FIGS. 5 to 9.
Note that in FIGS. 5 to 9, the same components as those of the structure shown in FIGS. 1 to 4 are given the same reference numerals. The arrows shown in FIGS. 6 to 9 indicate the direction in which the temperature-controlled air flows. Further, in FIG. 6, since it is difficult to illustrate the first angle θ1 shown in FIG. 2, illustration of the symbol θ1 is omitted.

In this case, the rotating shaft 26 is rotated so that the first angle θ1 becomes 0°. Specifically, the rotating shaft 26 is rotated to a position where the surface 31a of the center flap 31 faces downward and the surface 31a is parallel to the horizontal surface S.
In this state, the temperature-conditioned air supplied from the vehicle air conditioner 21 is blocked by the surface 31a of the center flap 31, so that the supply of temperature-conditioned air to the rear seat 15 is stopped.
The temperature-controlled air that has collided with the surface 31a of the center flap 31 flows toward the outside in the width direction of the center flap 31 (the J direction shown in FIG. 9).

As explained above, the second angle θ2 is configured to be larger than the first angle θ1, so even when the first angle θ1 is 0°, the second angle θ2 is , an angle larger than 0°. In other words, the side flaps 32 and 33 are in a state where the air outlet 35 is open.
Therefore, temperature-controlled air can be preferentially supplied to the front seat 13 via the side flaps 32 and 33.

Note that the temperature-controlled air supplied into the vehicle interior through the side flaps 32 and 33 is influenced by the temperature-controlled air flowing in the J direction (temperature-controlled air that collided with the surface 31a), and flows in the width direction of the vehicle 10. (K direction shown in FIG. 9).
As a result, when it is desired to preferentially supply temperature-controlled air to the front seats 13 of the vehicle 10, the temperature-controlled air is spread and supplied in the width direction of the front seats 13 (direction K shown in FIG. 9). can do.

(Effects of air blowing device for vehicle)
As described above, by making the first angle θ1 smaller than the second angle θ2 and making the opening ratio of the side flaps 32 and 33 larger than the opening ratio of the center flap 31, priority is given to the front seat 13. When supplying temperature-controlled air, by setting the angle to 0°, the temperature-controlled air that has collided with the center flap 31 is directed through the side flaps 32 and 33 in the width direction of the front seat 13 (vehicle 10 It can be spread out and supplied in the width direction).
On the other hand, when supplying temperature-controlled air to the front seats 13 and rear seats 15, by making the first angle larger than 0°, temperature-controlled air is supplied to the front seats 13 and rear seats 15. be able to.

Further, since it is only necessary to adjust the angles of the center flap 31 and the side flaps 32, 33 fixed to the same rotating shaft 26 in advance, it is possible to have a simple configuration.
In other words, with a simple configuration, the supply destination of temperature-controlled air led out from one outlet 35 can be switched between the front seat 13, the front seat 13 and the rear seat 15, and the front seat When supplying temperature-controlled air preferentially to the front seat 13, the temperature-controlled air can be spread and supplied in the width direction of the front seat 13.

<Second embodiment>
(Vehicle configuration)
A vehicle 40 equipped with a vehicle air blowing device 41 according to a second embodiment will be described with reference to FIGS. 10 to 13. Note that the arrows shown in FIGS. 11 to 13 schematically indicate the direction in which the temperature-controlled air flows. In FIGS. 10 to 13, the same components as those of the structure shown in FIGS. 1 to 9 are given the same reference numerals.

The vehicle 40 has the same configuration as the vehicle 10 except that it includes a vehicle air blowing device 41 instead of the vehicle air blowing device 20 that constitutes the vehicle 10 of the first embodiment.

(Configuration of vehicle air blowing device)
The vehicle air blowing device 41 has the same structure as the vehicle air blowing device 20 except that it has a center flap 43 instead of the center flap 31 that constitutes the vehicle air blowing device 20 of the first embodiment. ing.

(Center flap configuration)
The center flap 43 has a flat surface 43a and a convex curved surface 43b.
The plane 43a is arranged on the radially outer side of the rotating shaft 26. The plane 43a is a plane parallel to the axis O of the rotating shaft 26. The convex curved surface 43b is arranged to protrude outward in the radial direction of the rotating shaft 26. Both ends of the convex curved surface 43b arranged in the circumferential direction are connected to the flat surface 43a. The convex curved surface 43b is, for example, a part of a cylindrical surface.

The center flap 43 is fixed to the rotating shaft 26 such that a first angle θ3 formed between the horizontal surface S and the plane 43a is equal to a second angle θ4 formed between the horizontal surface S and the surfaces 32a and 33a.
In the second embodiment, the side flaps 32 and 33 are plate-shaped, and the center flap 43 is provided with a convex curved surface 43b that narrows the air outlet 35 and the flow path 36, so that the first angle θ3 and the second angle Even if θ4 is made equal, the aperture ratio of the side flaps 32 and 33 is configured to be larger than the aperture ratio of the center flap 43.

(Regarding the first and second angles θ3 and θ4 when supplying temperature-controlled air to the front seats and rear seats)
Here, the first and second angles θ3 and θ4 when supplying temperature-controlled air to the front seats and the rear seats will be explained with reference to FIGS. 11 to 13.
In this case, the first and second angles θ3 and θ4 can be appropriately set within a range that satisfies, for example, 180°<θ3<360° and 180°<θ4<360°.
By setting the first and second angles θ3 and θ4 within such ranges, the convex curved surface 43b does not narrow the air outlet 35 and the flow path 36 located on the rear side of the vehicle 40, and Since the air outlet 35 is not blocked by the side flaps 32 and 33, temperature-controlled air can be supplied to the front seats and rear seats of the vehicle 40.

(Regarding the first and second angles θ3 and θ4 when supplying temperature-controlled air preferentially to the front seats)
Next, the first and second angles θ3 and θ4 when temperature-controlled air is preferentially supplied to the front seats will be described with reference to FIGS. 14 to 16.
Note that in FIGS. 14 to 16, the same components as those of the structure shown in FIGS. 10 to 13 are given the same reference numerals. The arrows shown in FIGS. 14 to 16 indicate the direction in which the temperature-controlled air flows.

In this case, the first and second angles θ3 and θ4 can be appropriately set within a range that satisfies, for example, 0°≦θ3≦180° and 0°≦θ4≦180°.
By setting the first and second angles θ3 and θ4 within such ranges, the convex curved surface 43b makes it possible to narrow the air outlet 35 and the flow path 36 located on the rear side of the vehicle 40, and Since the air outlet 35 is no longer blocked by the side flaps 32 and 33, temperature-controlled air can be supplied preferentially to the front seats of the vehicle 40.

(Effects of air blowing device for vehicle)
With the above-described configuration, when supplying temperature-controlled air preferentially to the front seats, the convex curved surface 43b is located below the plane 43a and the flow path 36 and the air outlet located on the rear side of the vehicle 40. By arranging the convex curved surface 43b at a position where the mouth 35 is narrowed, it becomes possible to cause the temperature-adjusted air to collide with the convex curved surface 43b. Thereby, the temperature-controlled air that has collided with the convex curved surface 43b of the center flap 43 can be spread and supplied in the width direction of the front seat via the side flaps 32 and 33.

Furthermore, when supplying temperature-controlled air to the front seats and rear seats, the center flap can be moved to a position where the convex curved surface 43b does not narrow the flow path 36 and the air outlet 35 located on the rear side of the vehicle 40. 43 and the side flaps 32, 33, temperature-controlled air can be supplied to the front seats and the rear seats.
Furthermore, since the center flap 43 and the side flaps 32, 33 are fixed to the same rotating shaft 26, it is possible to have a simple structure.
In other words, with a simple configuration, the supply destination of temperature-controlled air led out from one air outlet 35 can be switched between the front seats, the front seats and the rear seats, and the front seats can be given priority. When supplying temperature-controlled air to the front seat, it can be spread across the width of the front seat.

Furthermore, when the vehicle 40 is not being driven (when the vehicle is stopped), by rotating the center flap 43 so that the flat surface 43a of the center flap 43 becomes the upper surface, the flat surface 43a of the center flap 43 and the side flaps 32 , 33 can be used to close the air outlet 35. Thereby, the aesthetic appearance of the upper surface 11a side of the instrument panel 11 can be improved.

<Third embodiment>
(Vehicle configuration)
A vehicle 50 equipped with a vehicle air blowing device 51 according to a third embodiment will be described with reference to FIGS. 17 and 18. Note that the arrows shown in FIG. 17 schematically indicate the direction in which the temperature-controlled air flows. In FIGS. 17 and 18, the same components as those of the structure shown in FIGS. 1 to 9 are given the same reference numerals.

The vehicle 50 has the same configuration as the vehicle 10 except that it includes a vehicle air blowing device 51 instead of the vehicle air blowing device 20 that constitutes the vehicle 10 of the first embodiment.

(Configuration of vehicle air blowing device)
The vehicle air blowing device 51 includes a first rotating shaft 52, a first actuator 53, and a second rotating shaft instead of the rotating shaft 26 and actuator 28 that constitute the vehicle air blowing device 20 of the first embodiment. It has the same structure as the vehicle air blowing device 20 except that it includes a shaft 55 and a second actuator 56.

The first rotating shaft 52 is a cylindrical rotating shaft, and is arranged at the air outlet 35 . The first rotating shaft 52 extends in the width direction of the vehicle 50 and is disposed at the center of the air outlet 35 in the longitudinal direction of the vehicle 50.
The first rotating shaft 52 has a notch 52A formed in the center. The cutout portion 52A extends in the width direction of the vehicle 50.

The first actuator 53 is connected to one end of the first rotating shaft 52. The first actuator 53 is electrically connected to the control section 29 and is controlled by the control section 29 . The first actuator 53 rotates the first rotating shaft 52 as necessary.

The second rotating shaft 55 is a rod-shaped rotating shaft having an outer diameter smaller than the inner diameter of the first rotating shaft 52. The second rotating shaft 55 is inserted inside the first rotating shaft 52 so that its axis line coincides with the axis of the first rotating shaft 52.
Thereby, a portion of the second rotating shaft 55 is exposed from the notch 52A formed in the first rotating shaft 52.

The second actuator 56 is connected to one end of the second rotating shaft 55. The second actuator 56 is electrically connected to the control section 29 and controlled by the control section 29 . The second actuator 56 rotates the second rotating shaft 55 as necessary.

The center flap 31 is fixed to a second rotating shaft 55 exposed from the notch 52A. Thereby, the center flap 31 rotates together with the second rotation shaft 55 when the second rotation shaft 55 is rotated.

The side flap 32 is fixed to the outer surface of the first rotating shaft 52 located on one side in the extending direction of the notch portion 52A (one side in the width direction of the vehicle 50). The side flap 33 is fixed to the outer surface of the second rotating shaft 55 located on the other side in the extending direction of the notch portion 52A (on the other side in the width direction of the vehicle 50). Thereby, the side flaps 32 and 33 rotate together with the first rotation shaft 52 when the first rotation shaft 52 is rotated.
That is, in the third embodiment, the rotation of the center flap 31 and the rotation of the side flaps 32 and 33 can be controlled separately.

The control unit 29 controls the aperture ratio of the side flaps 32, 33 by separately controlling the attitude of the center flap 31 and the attitude of the side flaps 32, 33 via the first and second actuators 53, 56. The aperture ratio is made larger than that of the center flap 31.

(Effects of air blowing device for vehicle)
With the above-described configuration, when supplying air to the front seats and the rear seats, the first and second actuators 53 and 56 are used to adjust the opening ratio of the side flaps 32 and 33 and the opening ratio of the center flap 31. It becomes possible to control both independently. Thereby, the degree of freedom in the supply direction of the temperature-controlled air led out from the air outlet 35 can be increased.

Although the preferred embodiments of the present disclosure have been described in detail above, the present disclosure is not limited to such specific embodiments, and various modifications may be made within the scope of the gist of the present disclosure described within the scope of the claims. It is possible to transform and change.

For example, in the first to third embodiments, the case where a pair of side flaps 32 and 33 are provided on both sides of the center flaps 31 and 43 has been described as an example, but it is also possible to provide one or more pairs of side flaps in the air outlet 35. Side flaps may also be provided.

<Additional notes>
The vehicle air blowing devices 20, 41, and 51 described in each embodiment can be understood, for example, as follows.

(1) The vehicular air blowing device 20, 41, 51 according to the first aspect includes the air blowing port 35 formed on the upper surface 11a of the instrument panel 11 of the vehicle 10, 40, 50 and the vehicular air conditioner 21. A casing 24 that defines a flow path 36 that guides temperature-controlled air to the air outlet 35, a center flap 31, 43 disposed at the center of the air outlet 35, and a width direction of the vehicle 10, 40, 50. and at least a pair of side flaps 32, 33 arranged to sandwich the center flaps 31, 43, the opening ratio of the side flaps 32, 33 being larger than the opening ratio of the center flaps 31, 43. It is configured to be.

In this way, by configuring the aperture ratio of the side flaps 32 and 33 to be larger than that of the center flaps 31 and 43, the center flaps 31 and 43 can be closed or the aperture ratio can be made as small as possible. By colliding with the center flaps 31, 43, it becomes possible to supply air that spreads in the width direction of the vehicle 10, 40, 50 from the side flaps 32, 33 to the front seat 13. As a result, if you want to preferentially supply temperature-controlled air to the front seats 13 of the vehicles 10, 40, 50, Temperature-controlled air can be distributed and supplied.

Moreover, by opening the center flaps 31, 43 within a range where the opening ratio of the center flaps 31, 43 is smaller than the opening ratio of the side flaps 32, 33, the front seats 13 and rear seats of the vehicle 10, 40, 50 can be opened. It becomes possible to supply temperature-controlled air to the seat 15.
That is, the supply destination of the air led out from one air outlet 35 can be switched between the front seat 13 and the front seat 13 and the rear seat 15.

(2) A vehicle air blowing device 20 according to a second aspect is the vehicle air blowing device 20 of (1), which extends in the width direction of the vehicle 10, is disposed at the blowing port 35, and has an axial line. The center flap 31 and the side flaps 32 and 33 are provided with a rotation shaft 26 that can rotate around O and an actuator 28 that rotates the rotation shaft 26. The first angle θ1 formed between the horizontal plane S orthogonal to the vertical direction and the center flap 31 is smaller than the second angle θ2 formed between the horizontal plane S and the side flaps 32 and 33. By making the first angle θ1 smaller than the second angle θ2, the aperture ratio of the side flaps 32 and 33 can be made larger than the aperture ratio of the center flap 31. Good too.

With this configuration, when preferentially supplying air to the front seats 13, the center flap 31 is placed in a position that blocks the air outlet 35, so that the air that collides with the center flap 31 is It can be spread and supplied in the width direction of the front seat 13 via the side flaps 32 and 33.
Furthermore, when supplying air to the front seats 13 and rear seats 15, air can be supplied to the front seats 13 and rear seats 15 by moving the center flap 31 to a position where the air outlet 35 is opened. can.

Moreover, since it is only necessary to adjust the angles of the center flap 31 and the side flaps 32, 33 that are fixed to the same rotation shaft 26, it is possible to have a simple configuration.
In other words, with a simple configuration, it is possible to switch the supply destination of air led out from one air outlet 35 to the front seat 13, the front seat 13 and the rear seat 15, and When preferentially supplying air, it can be spread out in the width direction of the front seat 13 and supplied.

(3) A vehicle air blowing device 41 according to a third aspect is the vehicle air blowing device 41 of (1), which extends in the width direction of the vehicle 40, is disposed at the blowing port 35, and has an axial line. A rotary shaft 26 rotatable around O, and an actuator 28 for rotating the rotary shaft 26, the center flap 43 and the side flaps 32, 33 are fixed to the rotary shaft 26, The center flap 43 has a flat surface 43a disposed radially outward of the rotating shaft 26, and a convex curved surface 43b that projects radially outward of the rotating shaft 26 and has both ends connected to the flat surface 43a. , the side flaps 32 and 33 are plate-shaped flaps, and a first angle θ3 formed between a horizontal plane S orthogonal to the vertical direction and the plane 43a of the center flap 43 is a first angle θ3 between the horizontal plane S and the side By making the second angle θ4 formed by the flaps 32 and 33 equal and the first angle θ3 and the second angle θ4 equal, the aperture ratio of the side flaps 32 and 33 is equal to that of the center flap 43. The aperture ratio may be larger than the aperture ratio.

With such a configuration, when supplying temperature-controlled air preferentially to the front seats 13, the convex curved surface 43b is located below the plane 43a and the flow path 36 located on the rear side of the vehicle 40. By arranging the convex curved surface 43b at a position where the air outlet 35 is narrowed, it becomes possible to cause the temperature-controlled air to collide with the convex curved surface 43b. Thereby, the temperature-controlled air that has collided with the convex curved surface 43b of the center flap 43 can be spread and supplied in the width direction of the front seat 13 via the side flaps 32 and 33.

In addition, when supplying temperature-controlled air to the front seats 13 and the rear seats 15, by moving the convex curved surface 43b to a position that does not narrow the flow path 36 and the air outlet 35 located on the rear side of the vehicle 40, Temperature-controlled air can be supplied to the front seat 13 and the rear seat 15 via the center flap 43 and the side flaps 32, 33.
Furthermore, since the center flap 43 and the side flaps 32, 33 are fixed to the same rotating shaft 26, it is possible to have a simple structure.
In other words, with a simple configuration, the supply destination of temperature-controlled air led out from one outlet 35 can be switched between the front seat 13, the front seat 13 and the rear seat 15, and the front seat When supplying temperature-controlled air preferentially to the front seat 13, the air can be spread out in the width direction of the front seat 13.

Furthermore, when the vehicle 40 is not being driven (when the vehicle is stopped), by rotating the center flap 43 so that the flat surface 43a of the center flap 43 becomes the upper surface, the flat surface 43a of the center flap 43 and the side flaps 32 , 33 can be used to close the air outlet 35. Thereby, the aesthetic appearance of the upper surface 11a side of the instrument panel 11 can be improved.

(4) A vehicle air blowing device 51 according to a fourth aspect is the vehicle air blowing device 51 of (1), which extends in the width direction of the vehicle 50, is disposed at the blowing port 35, and has an axial line. a first rotary shaft 52 rotatable in the periphery; a first actuator 53 for rotating the first rotary shaft 52; and a first actuator 53 extending in the width direction of the vehicle 50 and disposed at the air outlet 35; A second rotating shaft 55 that is rotatable around an axis, a second actuator 56 that rotates the second rotating shaft 55, and a control unit 29 that controls the first and second actuators 53 and 56. The side flaps 32 and 33 are fixed to the first rotating shaft 52, the center flap 31 is fixed to the second rotating shaft 55, and the control section 29 is fixed to the first rotating shaft 52. The aperture ratio of the side flaps 32 and 33 may be controlled to be larger than the aperture ratio of the center flap 31.

With this configuration, when supplying air to the front seat 13 and the rear seat 15, the first and second actuators 53, 56 are used to adjust the opening ratio of the side flaps 32, 33 and the center flap 31. Since it becomes possible to independently control the aperture ratio of the air outlet 35, the degree of freedom in the supply direction of the air led out from the air outlet 35 can be increased.
