Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a side ventilator mounted on an automobile.
[0002]
[Prior art]
In an automobile, an operation knob (which may be a dial) for moving a louver or the like attached to an outlet of a side ventilator is operated to direct a wind blown from the ventilator to a desired direction in a vehicle compartment. At this time, the air volume is adjusted by moving a shut valve with an operation dial separately provided.
[0003]
[Problems to be solved by the invention]
In the related art, in a case where it is not desired to blow the wind blown from the side ventilator toward the occupant, the direction in which the occupant is avoided, for example, the wind direction is directed to the outside of the passenger compartment. However, it is not preferable that the vertical louver is directed to the outside of the cabin more than a predetermined angle, and that the blowing air such as the cool air from the side ventilator is directly applied to the window glass. For this reason, it has been necessary to operate another operation dial provided at the outlet of the side ventilator and adjust the air volume with the shut valve in the side ventilator.
[0004]
In view of such circumstances, the present invention does not require the operation of a plurality of operation dials, and connects the operation of the vertical louver and the shut valve by a series of link mechanisms to operate both of them with a single operation dial. The purpose of the present invention is to prevent the blowing of wind on the inner wall of the room.
[0005]
[Means for Solving the Problems]
The present invention has been made to solve the above-mentioned problems, and employs the following technical means. That is, in the configuration of the present invention, a vertical louver in a vehicle side ventilator in which a vertical louver in a side ventilator and a shut valve are connected by a series of link mechanisms and both a vertical louver and a shut valve can be operated with one operation dial. A technical measure is adopted in which the shut-off valve moves so as to close the ventilation path in the side ventilator when the rotation limit reaches the side facing the side of the passenger compartment.
[0006]
Further, in addition to the configuration of the invention, a technical means for rotating the shut valve in the same direction as the rotating direction of the vertical louver is employed.
[0007]
【Example】
Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a perspective view showing a side ventilator of the present invention, and FIGS. 2 (a) and 2 (b) to 4 (a) and 4 (b) show an open / close state of a shut valve 7 of a side ventilator and a vertical louver 3 of the side ventilator of the present invention. Shows a bottom view and a cross-sectional view showing a state in which the vehicle faces inward. FIG. 5 is a longitudinal sectional view of the side ventilator of the present invention.
[0008]
First, a series of operations of the present invention will be described with reference to FIGS.
As can be understood from the vertical sectional view of FIG. 5, the operation dial 2 is connected to the vertical louver 3 by the link mechanism 4, and the vertical louver 3 is further mounted on the side ventilator 1 by the cam mechanism 5. 7 is connected. With this structure, when the operation dial 2 is operated, the vertical louver 3 rotates left and right via the link mechanism 4, the cam mechanism 5, and the engagement pin 6, and the shut valve 7 opens and closes in conjunction with each other. In order to fix the operation dial 2 and the cam mechanism 5, a washer 8 was attached so that an appropriate sliding torque was generated so that the occupant could operate more smoothly.
[0009]
The operation flow is as follows. First, by turning the operation dial 2 to the outside of the vehicle compartment B from the state where the vertical louver 3 is directed to the vehicle interior side A (see FIG. 1), the vertical louver 3 is moved to the vehicle exterior direction B. Turn to After the vertical louver 3 reaches the rotation limit, the operation dial 2 is further rotated to the outside B of the vehicle, so that the shut valve 7 in the side ventilator 1 is turned to the vertical louver with the vertical louver 3 facing the outside B of the vehicle. 3 is closed in the same direction as the rotation direction.
[0010]
Thus, a series of operations from the adjustment of the direction of the vertical louver 3 to the opening and closing of the shut valve 7 in the side ventilator 1 can be ensured by operating only one operation dial 2.
[0011]
Next, the configuration of the shut valve 7 in the side ventilator 1 will be described. For example, when getting into a car parked outdoors in the summer, cool air is first blown to the occupants, and after cooling down to the desired indoor temperature for a while, the occupants do not blow directly to the occupants. It is assumed that the setting is made such that In this case, the vertical louver 3 is directed more toward the outside B of the passenger compartment than the occupant so as not to blow the wind from the side ventilator toward the occupant. At this time, the vertical louver 3 is directed to the outside B of the vehicle from a predetermined angle, and the shut valve is linked in the closing direction so as not to blow the cold blowing wind directly on the window glass. I am holding it down.
[0012]
In the present invention, the shut-off valve 7 is turned from the state shown in FIG. 2 (b) to the state shown in FIG. 3 (b) by the rotation operation of the operation dial 2, that is, in the same rotation direction as the rotation direction of the vertical louver 3. 7 is turned, and most of the wind flowing through the ventilation path in the side ventilator 1 is collected on the vehicle exterior side B by the shut valve 7 to form an air wall (d in FIG. 3B) flowing parallel to the window glass. I do. The wind (b, c in FIG. 3 (b)) directed toward the window glass on the outside B of the vehicle by the vertical louver 3 is along the wall of air (d in FIG. 3 (b)) flowing parallel to the window glass. Since the direction is changed to the rear of the passenger compartment, it is possible to prevent the blown wind from directly hitting the window glass. In particular, immediately before the shut-off valve 7 completely closes the ventilation path in the side ventilator 1, the flow velocity of the wall of the air flowing parallel to the window glass becomes fastest, and the effect is increased. Even if the shut-off valve 7 is not completely closed, even if the vertical louver 3 is directed to the vehicle exterior side B beyond a predetermined angle, the blown wind does not directly hit the window glass. In addition, the airflow can be formed rearward of the passenger compartment without directly blowing the blowing air to the occupant.
[0013]
Next, the operation of the side ventilator 1 of the present invention will be described.
(1) When the vertical louver 3 is directed toward the vehicle interior (occupant side) A, the wind blown from the side ventilator 1 is blown toward the vehicle interior side (occupant side) A.
(2) When the operation dial 2 is rotated from the vehicle interior side A to the vehicle interior side B, and the vertical louver 3 is directed to the vehicle interior side B, the air blown from the side ventilator 1 is blown toward the window glass.
(3) In the conventional side ventilator, when the vertical louver is directed to the vehicle outside B from a predetermined angle, the wind comes to hit the window glass.
(4) Then, from the state where the vertical louver 3 is directed to the vehicle exterior B (the rotation limit of the vertical louver 3), the operation dial 2 is further rotated to the vehicle exterior B. Then, as described above, the shut valve 7 in the side ventilator 1 closes in the same rotation direction as the rotation direction of the vertical louver 3, and most of the wind flowing through the ventilation passage in the side ventilator 1 is collected on the vehicle exterior B. As a result, the wall of the air flowing parallel to the window glass is formed, so that the wind can be prevented from directly hitting the window glass, and can be sent to the rear of the passenger compartment without directly blowing the occupant to the blowing wind.
(5) When the operation dial 2 is further turned to the outside B of the vehicle compartment, the shut valve 7 completely closes the ventilation passage in the side ventilator 1. Thereby, the blowing of the wind from the side ventilator 1 is stopped.
[0014]
The side ventilator 1 and the link mechanism 4 are made of ABS (acrylonitrile-butadiene-styrene copolymer). The operation dial 2 and the cam mechanism 5 are made of polyacetal. The vertical louver 3, the engagement pin 6, and the shut valve 7 are made of PPC (composite material obtained by adding an additive to polypropylene). And the washer 8 is made of nylon. However, these constituent members are not limited to the above materials, and can be appropriately selected and used.
[0015]
【The invention's effect】
According to the present invention, as a result of employing the above configuration, the following effects can be obtained.
(1) A series of operations of the vertical louver and the shut valve of the side ventilator can be performed with only one operation dial.
(2) The vertical louver of the side ventilator is rotated to the outside of the cabin, and when the vertical louver reaches the rotation limit on the side facing the side of the cabin, the shut valve closes the ventilation passage in the side ventilator. You can stop the wind blowing toward you.
(3) Since the shut-off valve in the side ventilator moves in the same direction as the turning direction of the vertical louver at the turning limit, much of the wind flowing through the ventilation path in the side ventilator is collected outside the vehicle compartment by the shut-off valve, and the window is opened. It forms a wall of air flowing parallel to the glass. Due to the presence of the air wall, even if the vertical louver is directed to the outside of the passenger compartment from a predetermined angle, it is possible to prevent the wind blown toward the window glass from directly hitting the window glass.
