Description

  The present invention relates to a vehicle wind direction adjusting device provided with a plurality of louvers that can be opened and closed at a position of an air conditioning air outlet of a duct.

2. Description of the Related Art Conventionally, as a vehicle wind direction adjusting device, a plurality of louvers connected by a link are provided at a curved air outlet formed on one end side of a cylindrical case having both ends open, and can be opened and closed. When the air outlet is fully closed, the louvers are stored along the curve of the air outlet, and between the louver and the link, when the air outlet is fully opened by the louver, the louvers are in the same direction. What is connected with the link so that it may face is known (for example, refer to patent documents 1).
Japanese Patent No. 3507950

  However, in the conventional vehicle wind direction adjusting device, a plurality of louvers connected by links so as to face the same direction are provided at the air outlet formed on one end side of the cylindrical case so as to be freely opened and closed. Therefore, the middle part of the air outlet becomes an air guide at the adjacent louver, and wind direction adjustment is obtained, but the end of the air outlet becomes an air guide by the inner surface of the louver and the cylindrical case. Sex cannot be obtained.

  As described above, the conventional vehicle wind direction adjusting device has a configuration in which the air guide does not operate at the end of the air blowing port and the wind direction is not stable, and therefore, the direction of all the blowing winds from the air blowing port is the same. For example, an air curtain that regulates the wind direction in a narrow range cannot be formed. In addition, since the plurality of louvers are all opened and closed while maintaining a parallel relationship, it is not possible to obtain a nozzle-like wind direction adjusting property for concentrating the blowing air and a diffuser-like air direction adjusting property for diffusing the blowing air. There was a problem that it was not possible to control the wind direction with a high degree of freedom optimal for the blowout mode.

  The present invention has been made paying attention to the above problem, and provides a vehicle wind direction adjusting device capable of controlling the wind direction with a high degree of freedom by a louver angle aimed at the total amount of conditioned air flowing in a duct. With the goal.

In order to achieve the above object, in the present invention, in the vehicle wind direction adjusting device provided with a plurality of louvers that can be opened and closed at the position of the air conditioning air outlet of the duct,
The plurality of louvers are opposed to a first louver that opens and closes around a first rotation axis that is set along one side of the duct end surface that surrounds the air-conditioning air outlet, and the one side duct end surface. It has the 2nd louver which opens and closes around the 2nd axis of rotation set along the duct end face of the other one side which carries out.

Therefore, in the vehicle wind direction adjusting device of the present invention, when adjusting the wind direction from the air-conditioning wind outlet, the first louver opens and closes around the first rotation axis set along the duct end surface of one side. The second louver opens and closes around a second rotation axis set along the duct end surface of the other side facing the duct end surface of the one side.
That is, the first louver and the second louver are movable duct members that extend a pair of opposing duct end faces at an arbitrary louver angle, and the total amount of conditioned air flowing in the duct is between the first louver and the second louver. Is blown out.
For this reason, the wind direction can be adjusted by setting the louver angles of the first louver and the second louver to a predetermined angle with respect to the air-conditioning air blowing axis of the duct. Further, for example, when the first louver and the second louver are set parallel to each other, all the blowing winds can be blown out in parallel. Further, for example, if the first louver and the second louver are set to approach each other toward the louver tip, all the blowing air can be blown out as nozzle air. Further, for example, if the first louver and the second louver are set so as to be away from each other toward the louver tip, all the blowing air can be blown out as a diffuser wind.
As a result, the wind direction can be controlled with a high degree of freedom by the louver angle aimed at the total amount of the conditioned air flowing in the duct.

  Hereinafter, the best mode for realizing the vehicle wind direction adjusting apparatus of the present invention will be described based on Example 1 shown in the drawings.

  As shown in FIG. 2, the roof duct 4 is disposed in an oblique space 14 between the roof 9 and the roof lining 10. The roof cross section of the roof duct 4 has a flat cross section so as not to narrow the vehicle interior space. The roof duct 4 is surrounded by a lower end on the side window 7 side by a pair of long-side duct end faces along the axial direction of the roof duct 4 and a pair of short-side duct end faces in the direction orthogonal to the axis of the roof duct 4. An air curtain outlet 6 having a rectangular opening is opened.

  As shown in FIG. 2, the first air curtain louver 11 is a louver that opens and closes around a first rotation shaft 21 set along the end face of the long side duct on the side window 7 side. The first air curtain louver 11 rotates from the closed position shown in FIG. 2 counterclockwise to the maximum open position (see FIG. 7).

  As shown in FIG. 2, the second air curtain louver 12 is a louver that opens and closes around a second rotating shaft 22 set along the end face of the long side duct on the vehicle interior side. The second air curtain louver 12 rotates from the closed position shown in FIG. 2 counterclockwise to the maximum open position (see FIG. 7), and the rotation angle is larger than that of the first air curtain louver 11.

  As shown in FIG. 2, the roof cover 13 is rotated at the position of the air-conditioning air blowing opening 15 opened in the roof lining 10 by the rotation around the third rotation shaft 23 on the roof duct 4 side. A cover for opening and closing the outlet opening 15. The roof cover 13 rotates from the closed position shown in FIG. 2 clockwise to the maximum open position (see FIG. 7). Note that the same material (for example, non-woven fabric) as the inner surface of the roof lining 10 is attached to the surface of the roof cover 13 on the passenger compartment side.

  The drive gear mechanism 30 drives the first rotation shaft 21 of the first air curtain louver 11, the second rotation shaft 22 of the second air curtain louver 12, and the third rotation shaft 23 of the roof cover 13. This is a synchronous drive mechanism that is driven using a motor 40. As shown in FIG. 2, the drive gear mechanism 30 is set at the side position of the roof duct 4 where the shaft ends of the first rotating shaft 21, the second rotating shaft 22, and the third rotating shaft 23 are exposed. Has been. As shown in FIG. 3, the drive gear mechanism 30 includes a first gear 31 provided at the shaft end of the first rotation shaft 21 and a first gear provided at the shaft end of the second rotation shaft 22. Two gears 32, a third gear 33 provided at the shaft end of the third rotating shaft 23, a first idler gear 34 meshing with the first gear 31, and the first idler gear 34 and the third gear. 33 and a plurality of meshing gears constituted by a main drive gear 35 that is rotationally driven by the drive motor 40 and a second idler gear 36 that meshes with the first gear 31 and the second gear 32. The number of gear teeth is set such that first gear 31> main drive gear 35> second gear 32> third gear 33> first idler gear 34> second idler gear 36.

  The drive motor 40 is set at the rear position of the rear seat where the rear air conditioning unit 3 is disposed (for example, the position inside the rear panel, the trunk room, etc.), and as shown in FIG. The main drive gear 35 of the mechanism 30 is rotationally driven.

  The rear air-conditioning controller 50 is a wind direction adjustment drive control means for driving and controlling the drive motor 40 in accordance with the selected blow-out mode, and in accordance with an operation on the rear control panel 51, the blow-out mode (closes the air curtain blow-out port). Mode, side air curtain mode, roof side vent mode, side window differential mode, etc.) are selected.

Next, the operation will be described.
As shown in FIG. 4, a conventional vehicle wind direction adjusting device has a configuration in which a plurality of louvers that are linked by links so as to face the same direction are provided in an air blowing port formed on one end side of a cylindrical case so as to be openable and closable. It is.
For this reason, the middle part of the air outlet serves as an air guide for the adjacent louver, and the wind direction can be adjusted by bending the wind direction. However, the end of the air outlet is the air formed by the inner surfaces of the louver and the cylindrical case. It becomes a guide, wind direction adjustment is not obtained, and the wind direction is difficult to bend.

  In this way, with respect to the solution of the conventional device that the air guide does not operate at the extreme end of the air outlet, attention is paid to the fact that the louver setting position is moved from the duct internal position to the duct end face position. When adjusting the wind direction from the outlet, the first louver opens and closes around the first rotation axis set along the duct end surface of one side, and the second louver is the other side facing the duct end surface of one side. A configuration that opens and closes around the second rotation axis set along the end face of the duct is adopted.

  By adopting this configuration, the first louver and the second louver become a movable duct member that extends a pair of opposing duct end faces at an arbitrary louver angle, and the total amount of conditioned air flowing in the duct is the first louver. And the second louver is blown out. As a result, the wind direction can be controlled with a high degree of freedom by the louver angle aimed at the total amount of the conditioned air flowing in the duct.

  Hereinafter, the wind direction adjusting action by the vehicle wind direction adjusting device of the first embodiment is as follows: “in air curtain outlet closed mode”, “in side air curtain mode”, “in roof side vent mode”, “in side window differential mode” It is divided and explained.

[In air curtain outlet closed mode]
In the closed mode of the air curtain outlet 6, as shown in FIG. 2, in the rear air conditioning controller 50, the air curtain outlet 6 is closed by the first air curtain louver 11, and the second air curtain louver 12 is moved along the roof duct 4. The position of the flexible wire 41 connected to the drive motor 40 (= the position of the main drive gear 35) is controlled so that the air-conditioning wind blowing opening 15 is closed by the roof cover 13 at the avoidance position.

  Therefore, not only the air curtain outlet 6 is blocked, but also the air-conditioning air outlet opening 15 is blocked by the roof cover 13 so that even the presence of the air curtain outlet 6 is not noticed by passengers in the vehicle. In particular, in Example 1, since the same material as the inner surface of the roof lining 10 is attached to the surface of the roof cover 13 on the passenger compartment side, the roof lining 10 and the roof cover 13 are integrated, and the appearance is improved.

[In side air curtain mode]
FIG. 5 is an explanatory diagram of the wind direction adjusting operation in the side air curtain mode in the vehicle wind direction adjusting apparatus according to the first embodiment.

  In the side air curtain mode, as shown in FIG. 5, in the rear air conditioning controller 50, the air conditioning wind blowing opening 15 is opened by the roof cover 13, and the first air curtain louver 11 and the second air curtain louver 12 are connected to the side window 7. The position of the flexible wire 41 connected to the drive motor 40 (= the position of the main drive gear 35) is controlled so as to be arranged in parallel with each other.

  That is, when the main drive gear 35 is rotated from the position in the closed mode by the rotation angle θ, the first air curtain louver 11 is rotated counterclockwise in FIG. 5 by θ1, and the second air curtain louver 12 is illustrated. 5, the air curtain louvers 11 and 12 are arranged in parallel along the side window 7.

  Therefore, if the side air curtain mode is selected when the horizontal solar radiation enters the vehicle interior from the side window 7, an air curtain is formed at the inner position of the side window 7 by cold air or the like, and the temperature rise in the vehicle interior is suppressed, thereby cooling the vehicle. The performance can be improved and the radiant heat to the rear seat occupant can be reduced.

  In this side air curtain mode, the air curtain louvers 11 and 12 may be fixed in parallel arrangement along the side window 7, but in the rear air-conditioning controller 50, the main drive gear 35 is set at the rotational angle θ position. By rotating forward and backward as the center, the first air curtain louver 11 and the second air curtain louver 12 that are arranged in parallel along the side window 7 have a minute angle range (for example, ± 5 °) in which the parallelism is maintained. Degree).

  Therefore, when the main drive gear 35 is rotated forward and backward when the side air curtain mode is selected, both the air curtain louvers 11 and 12 become swing louvers, which substantially increases the thickness of the air curtain. In comparison, the radiant heat to the occupant can be more effectively reduced.

[In roof side vent mode]
FIG. 6 is an explanatory diagram of the wind direction adjusting operation in the roof side vent mode in the vehicle wind direction adjusting apparatus according to the first embodiment.

  In the roof side vent mode for blowing cool air, as shown in FIG. 6, in the rear air conditioning controller 50, the air cover air blowing opening 15 is opened by the roof cover 13, and the first air curtain louver 11 and the second air curtain louver 12 are Driven so as to be inclined toward the vehicle interior, and the inclination angle of the first air curtain louver 11 toward the vehicle interior is set to be larger than the inclination angle of the second air curtain louver 12 toward the vehicle interior. The position of the flexible wire 41 connected to the motor 40 (= the position of the main drive gear 35) is controlled.

  That is, when the main drive gear 35 is rotated from the position in the closed mode by an angle (θ−α) slightly smaller than the rotation angle θ of the parallel arrangement, the first air curtain louver 11 rotates counterclockwise in FIG. The second air curtain louver 12 rotates by (θ2-b) counterclockwise in FIG. 6. In this case, the inclination angle b from the position along the side window 7 of the second air curtain louver 11 is larger than the inclination angle a from the position along the side window 7 of the first air curtain louver 11. Both air curtain louvers 11 and 12 are opened toward the vehicle interior side and from the blowing width of the air curtain blowing port 6.

  Therefore, when it is detected by the occupant sensor or the like that no occupant is seated in the rear seat, by selecting the roof side vent mode that blows out the cold air, the cool air diffused from the air curtain outlet 6 is The rear passenger compartment can be effectively cooled.

[In side window differential mode]
FIG. 7 is an explanatory diagram of the wind direction adjusting operation in the side window differential mode in the vehicle wind direction adjusting apparatus of the first embodiment.

  In the side window differential mode, as shown in FIG. 7, in the rear air conditioning controller 50, the air-conditioning air blowing opening 15 is opened by the roof cover 13, and the first air curtain louver 11 and the second air curtain louver 12 are connected to the side window 7. And the inclination angle of the second air curtain louver 12 toward the side window 7 is set to be larger than the inclination angle of the first air curtain louver 11 toward the side window 7. The position of the flexible wire 41 connected to the motor 40 (= the position of the main drive gear 35) is controlled.

  That is, when the main drive gear 35 is rotated from the position in the closed mode by an angle (θ + β) slightly larger than the rotation angle θ of the parallel arrangement, the first air curtain louver 11 is rotated counterclockwise in FIG. 7 (θ1 + c). The second air curtain louver 12 is rotated counterclockwise by (θ2 + d) in FIG. In this case, the inclination angle d of the second air curtain louver 12 from the position along the side window 7 is larger than the inclination angle c from the position of the first air curtain louver 11 along the side window 7. Both the air curtain louvers 11 and 12 face toward the vehicle side window 7 and are closed by the blowing width of the air curtain blowing port 6.

  Therefore, in the summer, the side window 7 can be cooled to a non-condensing level by blowing the cold air from the air curtain outlet 6 toward the side window 7 with the nozzle wind, and the rear seat occupant Radiant heat from the side window 7 can be reduced. On the other hand, in the winter season, by blowing warm air from the air curtain outlet 6 toward the side window 7 with the nozzle wind, it is possible to prevent the side window 7 from being fogged and to warm the side window 7. The radiant heat taken away by the rear seat occupant can be reduced.

Next, the effect will be described.

The opening / closing operation of the cover 12 and the roof cover 13 can be controlled.

  (4) The air direction adjusting drive control means (rear air conditioning controller 50) closes the air curtain outlet 6 with the first air curtain louver 11 and closes the second air curtain louver 12 when the air curtain outlet 6 is in the closed mode. Is the avoidance position along the roof duct 4 and the roof cover 13 closes the air-conditioning air blowing opening 15 so that the air curtain blowing opening 6 is not exposed to the vehicle interior when the closed mode of the air curtain blowing opening 6 is selected. , You can achieve the appearance of creating a luxury car feeling.

  (5) In the side air curtain mode, the wind direction adjusting drive control means (rear air conditioning controller 50) opens the air conditioning wind blowing opening 15 by the roof cover 13, and the first air curtain louver 11 and the second air curtain. Since the louver 12 is arranged in parallel along the side window 7, when the side solar curtain mode is selected when the horizontal solar radiation enters the vehicle interior from the side window 7, the cooling performance can be improved and the rear Radiant heat to the seat occupant can be reduced.

  (6) In the side air curtain mode, the wind direction adjusting drive control means (rear air-conditioning controller 50) sets the first air curtain louver 11 and the second air curtain louver 12 arranged in parallel along the side window 7 in parallelism. In order to make the swing within a very small angle range, the air curtain louvers 11 and 12 are swung when the side air curtain mode is selected, so that the radiant heat to the occupant is more effective than in the louver fixed mode. Can be reduced.

Can be cooled.

  (8) In the side window differential mode, the wind direction adjusting drive control means (rear air conditioning controller 50) opens the air conditioning air blowing opening 15 by the roof cover 13, and the first air curtain louver 11 and the second air curtain. The louver 12 is inclined toward the side window 7, and the inclination angle of the second air curtain louver 12 toward the side window 7 is larger than the inclination angle of the first air curtain louver 11 toward the side window 7. Therefore, by selecting the side window differential mode in which the cold wind is blown strongly by the nozzle wind in the summer, the side window 7 can be cooled to a level without condensation, and the rear seat occupant from the side window 7 Radiant heat can be reduced. In addition, by selecting the side window differential mode in which warm air is blown strongly by the nozzle wind in winter, it is possible to prevent the side window 7 from being fogged and to reduce the radiant heat taken away by the rear seat occupant. .
