Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an air blowing device for a vehicle that sends air from an air conditioner into a vehicle interior.

(Conventional technology) The conventionally used air blowing device was developed in the 1980s.
-Although it is also shown in Publication No. 106044, for example, No. 6
As shown in the figure, the air outlet a is opened and closed by a single opening/closing plate c provided at the rear of the outlet grill body b to adjust the volume of air blown out from the air outlet. . This opening/closing plate c is configured to be rotated about the upper side of the opening/closing plate c as a fulcrum by an operating lever d provided beside the air outlet a.

(Problem to be solved by the invention) However, when opening the air outlet a, such an opening/closing plate c protrudes rearward by a length that is approximately equal to the vertical width of the air outlet a. It is necessary to secure a space in the ventilation duct that does not hinder the movement of the air conditioner c, and the disadvantage is that the ventilation duct must be enlarged or the air outlet a must be made to protrude into the passenger compartment.

Therefore, an object of this invention is to provide an air blowing device for a vehicle in which the rearward protruding length of the opening/closing plate is reduced to reduce the space required for installation.

(Means for Solving the Problems) Therefore, the gist of this invention is to provide a rotatable blow-off grill main body having a wind direction changing plate at the air blow-off port, and to The air outlet is divided into a plurality of sections, covered with a plurality of opening/closing plates that are rotatably supported in the direction of the dividing line of the air outlet, and the plurality of opening/closing plates are connected so as to be interlocked by a connecting device. The operation lever provided on the opening/closing plate allows other opening/closing plates to simultaneously open and close the air outlet.

(Function) Therefore, the air outlet is opened and closed by a plurality of opening/closing plates supported in the direction of the dividing line that bisects the air outlet. The length can be reduced to 1/2, and therefore the above object can be achieved.

(Example) An example of this invention will be described below with reference to the drawings.

In FIG. 3, an operation panel 1 of an air blowing device installed in a ventilation duct of an air conditioner for an automobile is shown. The operation panel 1 has a rectangular shape made of synthetic resin, and has a panel frame 2 on its periphery that bulges toward the passenger compartment. The lower part is an inclined surface recessed toward the rear of the operation panel 1 in a plane parallel to the operating panel 1. Two light frames 3, 3 with a rectangular cross section projecting rearward are provided on the upper plane in the longitudinal direction of the operation panel 1, and within these light frames 3, 3, a square lens 4 and a rectangular lens 4 are provided.
A spotlight 6 consisting of a light emitting device 5 and a light emitting device 5 assembled at the rear of the spotlight 6 is housed. Further, in a portion closer to the center of the operation panel 1 than the respective light frames 3, 3, switches 7, 7 for turning on and off the light emitting bodies of the respective light emitting devices 5, 5 are provided. On the other hand, on the inclined surface, air blowing frames 8, 8 having a rectangular cross section and projecting rearward are provided at two places on the left and right, and elongated holes 22, 22 extending in the vertical direction are provided at approximately the center of the operation panel 1. is formed. The air outlet 9 is also shown in FIGS. 1 and 2, and is composed of the air blowing frame 8 and an opening/closing plate holding frame 10 connected to the rear of the air blowing frame. The opening/closing plate holding frame 10 has a cylindrical shape that matches the cross-sectional shape of the air blowing frame 8, and has an opening/closing plate 11 (described later) that opens and closes the air outlet 9 on the rear end surface.
a and 11b are provided.

The blowout grill main body 12 is provided at the air blowout port 9, and specifically, a semicircular notch is formed in each of the frames 8 and 10 at the joint portion between the air blowout frame 8 and the opening/closing plate holding frame 10. support hole 14 facing each other.
Horizontal shafts 15, 15 protruding from both sides of the blow-off grille 12 are rotatably supported in the support hole 14. A plurality of wind direction changing plates 16 are axially mounted on the vertically opposing sides of the outlet grill main body 12, connected to a common horizontal rod 17 via hinges, and connected to a knob 18 provided on the central wind direction changing plate 16a. can be tilted as a unit in the same direction.

Two opening/closing plates 11a and 11b are provided on the upper and lower sides of the air outlet 9, and are formed to have a size that divides the air outlet 9 into two approximately equally at the upper and lower sides, and one side is attached to both the left and right end surfaces of the opening/closing plate holding frame 10. The other one is rotatably supported on one longitudinal side at the lower end of both side surfaces, approximately at the center. Both opening/closing 11a, 1
1b are connected by a U-shaped connector 19 via a protruding plate formed on the back surface, and when one opening/closing plate 11a moves, the other opening/closing plate 11b follows and opens the air outlet 9. It has a structure that allows it to be opened and closed at the same time. Further, the upper opening/closing plates 11a, 11b are provided with a driving lever 20 extending along the side surface of the opening/closing plate holding frame 10, and an operating lever 21 is connected via this driving lever 20.

The operating lever 21 includes an arm portion 21a and a head portion 21 formed by protruding the tip of the arm portion 21a.
b, and the elongated hole 22 of the operation panel 1.
Insert the arm part 21a from the vehicle interior side, provide the moderation holding plate 23 on the arm part 21a behind the operation panel 1, sandwich the operation panel 1 between the moderation holding plate 23 and the head 21b, and then It is slidably attached to the hole 22. The connection with the drive lever 20 is through a cam groove 24 formed in the drive lever 20.
This is done by locking a pin 25 that passes through the operating lever 21.

In the above configuration, when the operating lever 21 is lowered to the lower end of the elongated hole 22 as shown in FIG. It is not being sent. If the operating lever 21 is gradually raised from this state to the upper end of the elongated hole 22 as shown in FIG. At the same time as the rotation, the lower opening/closing plate 11b connected to the upper opening/closing plate 11a via the connector 19 also rotates, and the air outlet 9 gradually opens. When the operating lever 21 is at the upper end of the elongated hole 22, the air outlet 9 is also in its most open state, and both the opening/closing plates 11a and 11b are horizontal. Note that since the operation 21 moves in parallel when sliding through the elongated hole 22, the head 21b of the operation lever 21 does not protrude in an arc from the surface of the operation panel 1, resulting in a good appearance. becomes.
Further, in this embodiment, there are two opening/closing plates for opening and closing the air outlet, but the number is not limited to this, and a plurality of opening/closing plates, such as three, may be used.

(Effects of the invention) As described above, according to this invention, a plurality of opening/closing plates connected by connectors are provided at the rear of the outlet grill body provided at the air outlet, and each opening/closing plate is connected to the air outlet. By pivoting the outlet in the direction of the dividing line, multiple opening/closing plates can open and close the air outlet at the same time, so the length of the opening/closing plate protruding from the rear of the air outlet can be shortened to one-fold. , the space required for installation can be reduced.
