Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a door mirror of an automobile that is used to actively introduce wind from the vehicle into the interior of the vehicle.

(Prior art) Opening the window glass while the car is running to let the wind into the car cabin gives the occupants a refreshing feeling, but in cars that do not have so-called triangular windows in the front door, the driver's seat and The reality is that it is difficult for this driving wind to blow into the front seat side where the passenger seat is located. Therefore, as disclosed in Japanese Utility Model Application Publication No. 54-53253, there is a system that uses a door mirror installed in front of the front door to actively introduce wind from the vehicle toward the front seat side. . As shown in FIG. 1, the depth of the mirror case 3 of the door mirror 2 provided on the front door 1 is increased, and the side surface 3a of the case 3 on the vehicle interior side is inclined from the front outside toward the rear vehicle interior. The side surface 3a is formed to have a smooth surface, and the wind is guided into the vehicle interior by the side surface 3a.

However, according to the above-mentioned invention, wind can be effectively introduced into the vehicle interior by lowering the window glass, but since the direction of the introduced wind is constant, for example, the seat position may be adjusted by the occupant. When the passenger is moved back and forth, the introduced wind may not be able to effectively hit the occupant. Furthermore, the wind that hits the side surface 3a of the mirror case 3 always blows into the vehicle interior when the window glass is opened, which is even more inconvenient when the user does not want to be exposed to the wind. In particular, if the vehicle is driven with the window glass open during rain, rain will enter the vehicle interior. Furthermore, when the window glass is closed, the wind whose direction is changed by the side surface 3a of the mirror case 3 hits the window glass, so the wind noise while driving becomes even louder, and the air blows at high speed along the window glass. The flow causes a phenomenon in which the glass is sucked out, causing the glass to vibrate and making the noise even louder.

(Purpose of the invention) The present invention solves the above-mentioned inconveniences when using door mirrors to introduce wind into the vehicle interior. In addition to making it possible to
When the introduction of the wind is unnecessary, it can be shut off, thereby allowing the running wind to be introduced into the vehicle interior as necessary and in an optimal condition. In addition, when the window glass is closed, the wind deflected by the door mirror hits the glass, preventing wind noise, and actively utilizes the wind that hits the window glass during rain. The purpose is to improve the visibility of the door mirror by removing raindrops adhering to the window glass by appropriately setting the air volume and direction.

(Structure of the invention) The automobile door mirror according to the invention is structured as follows in order to achieve the above object. That is, in a door mirror provided on a front door equipped with a window glass that can be raised and lowered, there is a base of the door mirror main body, and upper and lower wall shapes that are connected to the upper and lower ends of the base and extend outward from the outer surface of the window glass. and the side surface of the mirror case on the window glass side provided between both wall-shaped parts form a ventilation duct. The slope slopes from the rear toward the passenger compartment. A fin for controlling the wind direction is provided in the ventilation duct, which can close the duct and whose degree of opening can be adjusted.

According to such a configuration, while the car is running,
If you leave the window glass open, the wind passing through the ventilation duct will be redirected by the side of the mirror case on the window glass side and blown into the passenger compartment through the window. The position of the fins can be arbitrarily adjusted, and by closing the duct with the fins, it is also possible to prevent wind from blowing into the vehicle interior. In addition, when the window glass is closed, it is possible to prevent the noise caused by the wind from colliding with the window glass, and when it rains, by adjusting the direction and strength of this wind, the window glass can be Adhering raindrops can be removed to ensure good visibility of the door mirror through the window glass.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

As shown in FIG. 2, a corner bracket 14 is provided at the front of a front door 12 of an automobile 11 at a corner where a sash 13 of the door 12 stands diagonally rearward, and a door mirror 20 is attached to the bracket 14. It is being Here, a groove 14a is provided at the rear end of the corner bracket 14 to guide the elevation of the window glass 15, as shown in FIG.
is provided.

As shown in FIGS. 3 to 5, the main body 21 of the door mirror 20 includes a base 21a and upper and lower walls connected to the upper and lower ends of the base 21a and extending horizontally outward from the outer surface of the window glass 15. shaped portions 21b, 21
c, and a mirror case 21d connected to the ends of both wall-shaped parts 21b and 21c, the mirror 22 is housed in the mirror case 21d, and the base 21a is connected to the corner bracket of the front door 12. 14 through a seal packing 23 with a screw 24. A side surface 2 of the mirror case 21d on the window glass 15 side
1d' is an inclined surface that is spaced from the outer surface of the window glass 15 and slopes from the front outside to the rear passenger compartment side, and this side surface 21d' and the upper and lower wall portions 21b, 21
c and the base 21a form a ventilation duct 25 that directs into the vehicle interior from the front through the window.

In this ventilation duct 25, there is a swingable fin 2 for controlling the wind direction and closing the ventilation duct 25.
6 is provided. As shown in FIG. 5, one side of the fin 26 is provided with a vertical shaft 26a, whose upper and lower ends are supported by a bearing member 27 from the outside, and at the center of the shaft 26a. The portion is supported from the inside by a presser plate 28. In this state, the bearing member 27 is attached to the base portion 21a with the presser plate 28 in between by screws 29...29. As a result, the fins 26 are made swingable around the shaft portion 26a, and from the position where the ventilation duct 25 is maximally opened as shown by the solid line in FIG.
It can be set at any position up to a position where it contacts the side surface 21d' of d and closes the duct 25. In this case, the presser plate 28 provides resistance to the shaft portion 26a, so that the position of the fin 26 does not change easily even if the fin 26 is exposed to wind while traveling.

A frame 31 is attached to the mirror case 21d on pillars 30 erected from the inner bottom surface of the case, and a pivot 32 is provided at the center of the frame 31. By fitting the holding member 33 to the mirror pivot 32, the mirror 2
2 is maintained so that the mirror surface can be set in any direction.

According to the above configuration, when the window glass 15 is opened while the automobile 11 is running, the fin 2 provided in the ventilation duct 25 of the door mirror 20 is opened.
6 is set at the position shown by the solid line in FIG. 4, the direction of the running wind entering the ventilation duct 25 is changed by the door-side side surface 21d' of the mirror case 21d forming the duct 25, and is blown into the vehicle interior. .
In that case, the fins 26 are swingable around the shaft portion 26a and can be set at any position, so the direction and volume of the running air blown into the vehicle interior from the ventilation duct 25 can be changed, and the seat position or running speed can be changed. You can adjust the wind direction and volume according to your preference.

On the other hand, when the fin 26 is set so that the tip end 26b contacts the door-side side surface 21d' of the mirror case 21d as shown by the chain line in FIG. 4, the ventilation duct 25 is closed by the fin 26, This means that the wind entering the vehicle interior is blocked. As a result, even if the vehicle runs with the window glass 15 lowered when the vehicle does not want to be exposed to more wind than necessary or when it is raining lightly, unnecessary wind blowing and rain can be prevented from entering. In addition, since the ventilation duct 25 is closed by the fin 26, the window glass 15
When the window glass 1 is closed, the window glass 1 passes through the ventilation duct 25.
This prevents the vehicle from being hit hard by the wind while the vehicle is traveling, thereby preventing the wind noise from increasing while the vehicle is traveling or from causing the window glass to vibrate due to the suction. Furthermore, when it rains, by adjusting the position of the fins 26 with the window glass 15 closed, the wind from the vehicle can be applied to an appropriate position on the window glass 15 with an appropriate strength. to remove raindrops adhering to the window glass 15,
Good visibility of the door mirror 22 through the glass 15 can be obtained.

Next, another embodiment of the present invention shown in FIG. 6 will be described. In this embodiment, the fins provided in the ventilation duct are provided on the mirror case side of the door mirror body.
