BACKGROUND OF THE INVENTION
The present invention relates to a vehicle wind direction adjusting device capable of blowing air from an instrument panel to a front window panel and a rear seat side.
[0002]
[Prior art]
An air conditioner is provided inside the instrument panel, and air adjusted to an appropriate temperature is blown out from various openings provided in the instrument panel into the vehicle interior. For example, there are a vent mode that blows air toward the front seat occupant, a foot mode that blows air toward the feet of the occupant, and a differential mode that blows out air toward the front window panel and eliminates cloudiness. Recently, there is also a rear seat mode that sends air to the rear seat occupant beyond the head of the front seat occupant (refer to Japanese Patent Laid-Open No. 10-287121 for similar technology).
[0003]
As the rear seat mode, a nozzle that rotates back and forth is provided at the top of the instrument panel. This nozzle is also used as a differential mode. By setting it to a forward angle, it becomes a differential mode in which air is blown to the front window panel side, and by setting it to a rear angle, it becomes a rear seat mode in which air is blown to the rear seat side.
[0004]
[Problems to be solved by the invention]
However, in such a conventional technique, since the nozzle protrudes from the upper part of the instrument panel, the upper structure of the instrument panel becomes complicated and the appearance of the vicinity of the instrument panel deteriorates. ing.

[0018]
DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention will be described below with reference to the drawings.
[0019]
1 to 8 are views showing a first embodiment of the present invention. FIG. 1 is a cross-sectional view showing the structure of the upper part of the instrument panel 1. A front window panel 2 is disposed in front of the instrument panel 1 in a state of being inclined rearward. An opening 3 for blowing out air is formed on the upper surface of the instrument panel 1, and an air conditioning duct 4 is connected to the opening 3 from the inside of the instrument panel 1.
[0020]
In the opening 3, eight louvers 5a to 5h are arranged in the front-rear direction. Each louver 5a to 5h has a structure that is long in the vehicle width direction, and the whole pivots downward about the shaft pin 6 projecting from the front end of both ends in the vehicle width direction to adjust the angle in the front-rear direction. It is free. In addition, guide pins 7 project from the rear ends of both ends of the louvers 5a to 5h in the vehicle width direction.
[0021]
The guide pins 7 of the louvers 5a to 5h are movably engaged in guide holes 9a to 9h formed in the upper part of the link 8. The link 8 has leg portions 10 at the front and rear, and a cam pin 11 projects from the lower end of the leg portion 10. The link 8 is supported so as to be movable only in the front-rear direction.
[0022]
A pair of front and rear cam gears 12 are provided for the front and rear leg portions 10 of the link 8, respectively. The cam gear 12 has a gear portion 12a at the center, and a cam groove 13 is recessed in the side surface. A cam pin 11 projecting from the lower end of the leg 10 is movably engaged in the cam groove 13. The cam groove 13 has a fully closed position 13a set so as to be positioned farthest from the center and on the rear side, and a differential position 13b set so as to be positioned slightly far and slightly on the rear side at both ends. The rear seat position 13c is set so as to be located closest to the center and on the most front side.
[0023]
The gear portions 12 a of the pair of cam gears 12 mesh with a gear portion 14 a provided at the center of the operation dial 14 as one “manual operation portion”. A part of the operation dial 14 is exposed upward from the instrument panel 1 and can be manually rotated. In this embodiment, the above-described link 8, cam gear 12, and operation dial 14 constitute “operation means”.
[0024]
As shown in FIG. 4, the guide holes 9 a to 9 h formed in the upper part of the link 8 basically have a shape in which the vertical holes 16 a to 16 h are formed upward from the rear ends of the horizontal holes 15 a to 15 h. The horizontal holes 15a to 15h gradually become closer to the vertical holes 16a to 16h toward the front side. In the guide hole 9h at the front end, the angle of the horizontal hole 15h matches the vertical hole 16h, and the guide hole 9h is linear. It has become. As the angle of the horizontal holes 15a to 15h increases, the amount of movement of the guide pin 7 in the horizontal direction decreases. Therefore, the amount of movement in the horizontal direction is minimum (zero) in the guide hole 9h at the front end, and the amount of movement in the horizontal direction is maximum in the guide hole 9a at the rear end. Further, the vertical holes 16a to 16h are inclined forward by an angle θ (see FIG. 6), and when the guide hole 9a or the like advances, the guide pin 7 can be lowered and guided to the horizontal hole 15a or the like.
[0025]
Next, the operation of this embodiment will be described.
[0026]
Fully closed mode (see Fig. 1)
In the state where the operation dial 14 is fully rotated in the closing direction, the cam pin 11 of the link 8 is engaged with the fully closed position 13a in the cam groove 13 of the cam gear 12, and the link 8 is in the most rearward position. ing. In this state, the guide pins 7 of the louvers 5a to 5h are positioned in the lateral holes 15a to 15h of the guide holes 9a to 9h, and the louvers 5a to 5h are all in a horizontal state and shield the opening 3. .
[0027]
Rear seat mode (see Fig. 2 and Fig. 7)
Next, when the operation dial 14 is rotated in the opening direction, the cam pin 11 engages with the rear seat position 13c, and the link 8 moves forward to the frontmost position. When the link 8 moves to the front side, the guide holes 9a to 9h also move forward relative to the guide pins 7 of the louvers 5a to 5h. When the guide holes 9a to 9h move forward, the vertical holes 16a to 16h are inclined forward by an angle θ, so that the guide pin 7 extends from the inside of the vertical holes 16a to 16h to the rear end position of the horizontal holes 15a to 15h. Pushed down. Then, all the guide pins 7 are moved forward by the same amount in a state where they are pushed to the rear ends of the horizontal holes 15a to 15h, and the louvers 5a to 5h rotate around the shaft pins 6 so that all the louvers 5a to 5h are in a diagonally rearward parallel state, and air can be blown out to the rear seat side.
[0028]
Differential mode (See Fig. 1 and Fig. 8)
When the operation dial 14 is further rotated in the opening direction, the cam pin 11 is engaged with the differential position 13b, and the link 8 is slightly retracted. When the link 8 is retracted, the guide holes 9 a to 9 h are also retracted relative to the guide pin 7. When the guide holes 9a to 9h are retracted, the front guide hole 9h has a large angle such as the horizontal hole 15h and the amount of the guide pin 7 that can move within the horizontal hole 15h (play amount) is small. The amount by which the guide pin 7 moves rearward is larger, and the rearmost louver 5a completely absorbs the backward movement of the guide pin 7 in the lateral hole 15a, and there is no change in angle as in the rear seat mode. Accordingly, as a result, the louvers 5a to 5h are in an upward radiating state, and air can be blown out in a diffused manner toward the front window panel 2, so that fogging of the front window panel 2 can be eliminated in a wide range. .
[0029]
According to this embodiment, since only the angle of the louvers 5a to 5h provided in the opening 3 of the instrument panel 1 is changed, the differential mode and the rear seat mode can be obtained. There is no need to provide a projection such as a nozzle, and the appearance near the top of the instrument panel 1 is improved. Further, the operability is good because the rear seat mode and the differential mode can be obtained by operating only one operation dial 14.
[0030]
9 to 11 are views showing a second embodiment of the present invention. In the second embodiment, eight louvers 5a to 5h are divided into four front groups 5e to 5h and rear groups 5a to 5d, respectively, and operating means (not shown) having the same structure as the previous embodiment. Operated by. In the second embodiment, in addition to the fully closed state, the following three effective states can be obtained.
[0031]
Simultaneous blowing in both modes (Figure 9)
The front groups 5e to 5h are set to the differential mode, the rear groups 5a to 5d are set to the rear seat mode, and the differential mode and the rear seat mode are obtained at the same time. Since the front groups 5e to 5h close to the front window panel 2 are set to the differential mode, it is possible to reliably apply the diffused air to the front window panel 2, and the air volume is half that of the total ventilation area of the opening 3. It can clear the cloudiness sufficiently. Further, since the rear groups 5a to 5d close to the rear seat are set to the rear seat mode, it is easy to allow air to reach the rear seat. Although it is possible to structurally blow out the def mode and the rear seat mode at the same time, it is not effective because they cancel each other out.
[0032]
Differential mode single blowout (Figure 10)
The front groups 5e to 5h were set to the differential mode, and the rear groups 5a to 5d were shielded. Since the rear groups 5a to 5d are shielded, the air momentum from the front groups 5e to 5h increases, and the effect as the differential mode increases. Although it is preferable to set the front groups 5e to 5h to the differential mode by the amount close to the front window panel 2, the front groups 5e to 5h can be shielded and the rear groups 5a to 5d can be set to the differential mode.
[0033]
Rear blowout on the rear board (Fig. 11)
The front groups 5e to 5h were shielded, and the rear groups 5a to 5d were set to the rear seat mode. Since the front groups 5e to 5h are shielded, the momentum of the air from the rear groups 5a to 5d increases, and the effect as the rear seat mode increases. Although it is preferable to set the rear groups 5a to 5d to the rear seat mode by the amount close to the rear seat, the rear groups 5a to 5d can be shielded and the front groups 5e to 5h can be set to the rear seat mode. .
[0034]
FIG. 12 is a diagram showing a third embodiment of the present invention. In the third embodiment, the opening 3 of the instrument panel 1 is covered with a perforated metal cover 17 that allows ventilation, and similar louvers 5a to 5h are provided therein. Since the internal structure (louvers 5a to 5h) of the opening 3 is hidden by the cover 17, the appearance is improved. The cover 17 may be made of a material that can be ventilated, and may be formed of a mesh or the like instead of the punching metal.
[0035]
【The invention's effect】
According to the present invention, the diff mode and the rear seat mode can be obtained simply by changing the angle of the louver provided at the opening of the instrument panel. Therefore, a projection like a conventional nozzle is formed on the top of the instrument panel. There is no need to provide it, and the appearance near the top of the instrument panel is improved.
