Description

[Detailed Description of the Invention] Technical Field The present invention relates to a door mirror device for an automobile.

BACKGROUND OF THE INVENTION Automotive door mirror devices having a mirror holder attached to the front of a motor vehicle door and a mirror supported by the holder are well known in the art. Such mirror devices have the advantage of improving the appearance of the vehicle, and are therefore widely used in modern vehicles.

However, when this type of door mirror device is used, when the car is driving in the rain, the wind flowing from the front is blocked by the mirror device, so water droplets attached to the outer surface of the window glass of the door located behind it are not blown away. When the driver looks in the mirror, the attached water droplets may obstruct the driver's view. Therefore, the driver has to wipe the window glass each time, which is very cumbersome to operate.

In order to eliminate this kind of problem, the wind flowing from the front is directed to the part of the mirror holder between the mirror supported by the mirror holder and the part where this mirror holder is attached to the door. A door mirror device having a ventilation hole leading to the outside has been proposed (see Japanese Utility Model Application Publication No. 105542/1983). In this device, water droplets adhering to the outer surface of the window glass can be blown away by air passing through the ventilation holes.

However, in conventional door mirror devices of this type, the vertical position of the outer surface of the window glass, which can blow water droplets away by the wind passing through the ventilation holes, is always constant, so it was possible to clear the field of vision for some drivers. Even so, it may not be possible to clear the field of view for other drivers of different heights, and it cannot be expected to ensure complete visibility for all drivers.

Purpose The present invention was made based on the above-mentioned novel recognition, and its purpose is to eliminate the above-mentioned conventional drawbacks and to provide an automobile door mirror device that can clear the field of vision for drivers of any height. Our goal is to provide the following.

Configuration In order to achieve the above object, the present invention includes a mirror holder attached to the front part of an automobile door and a mirror supported by the holder, and the mirror supported by the mirror holder and the mirror. In a door mirror device for an automobile, a ventilation hole is formed in a portion of the mirror holder between the mirror holder and a portion where the mirror holder is attached to the door to guide wind flowing from the front to the outer surface of the window glass of the door. , proposes a door mirror device in which at least one movable guide member that adjusts the vertical direction of the air passing through the ventilation hole is rotatably supported in the vertical direction.

Function The movable guide member is tilted to adjust the vertical direction of the wind passing through the ventilation hole, thereby blowing away water droplets attached to the outer surface of the door window glass.

Examples Examples of the present invention will be described below with reference to the drawings.
In addition, the above-mentioned drawbacks of the conventional technology will be explained more specifically with reference to the drawings.

FIG. 1 is a perspective view showing the front of an automobile equipped with a door mirror device according to the present invention, in which 1 is a front window fixed to the vehicle body 2, and 3 is a door pivotally connected to the vehicle body 2 so as to be openable and closable. A door mirror device 5 is attached to a window frame 4 of this door 3. 11 is a window glass supported by the door 3 so as to be movable up and down.

The door mirror device 5 shown as an example in the figure is a mirror holder consisting of a mirror base 6 fixed to a window frame 4 and a mirror case 7 pivotally attached to the mirror base 6 so as to be rotatable in the direction of arrow A. 8
and a mirror 9 supported by a mirror case 7 of this mirror holder, and the mirror holder 8 is attached to the front part of the door 3. The driver seated in the driver's cab can drive while checking the rear visibility using the mirror 9, and if the mirror case 7 gets in the way, it can be folded by rotating it in the direction of arrow A. can.

Here, in the case of a door mirror device commonly used in the past, wind flowing from the front when the automobile is running flows around the mirror holder 8 as shown by arrow B and flows away backward. Conversely, the strong wind does not hit the outer surface of the window glass located behind the mirror holder 8. For this reason, when a car is driven in the rain, water droplets adhering to the outer surface of the window glass, which is not exposed to strong winds, are difficult to blow away and often remain attached there. As a result, when the driver tries to check the rear view by looking at the mirror 9, the water droplets on the outer surface of the window glass become an obstacle.
Visibility may be obstructed.

Therefore, in the illustrated mirror device 5, the flow from the front is applied to the mirror holder portion between the mirror 9 supported by the mirror holder 8 and the portion where the mirror holder 8 is attached to the door 3. A ventilation hole 10 is formed to guide wind to the outer surface of the window glass of the door 3. That is, the wind flowing from the front is made to flow through this ventilation hole 10 as shown by arrow C, and as shown in FIG. It was configured so that it could be blown away. However, if only the ventilation hole 10 is provided, it is difficult to completely clear the field of view because the flow of air is obstructed by parts of the mirror holder other than the ventilation hole.

This will be explained with reference to FIG. 3a. Fig. 3a is an explanatory view of the outside of the car from inside the car, and assuming that the window glass area surrounded by chain lines is the area where water droplets are blown away by the wind passing through the ventilation hole 10, the diagonal lines around it are Water droplets remain attached to the attached parts. At this time, when the driver P1 tries to look at the mirror 9, his visibility is obstructed by the water droplets shown with diagonal lines.

Therefore, suppose that the shape of the ventilation hole 10 is changed so that the wind passing through it hits the upper part surrounded by the broken line in FIG. However, if this is done, the visibility of the short driver P2, especially when seated at the rear, will be obstructed.

As described above, simply providing the ventilation holes 10 may not be able to clear the driver's field of vision depending on the body size and seating position of the driver, and it is difficult to expect complete visibility to be ensured with only the ventilation holes.

Therefore, in the door mirror device according to the present invention, as illustrated in FIG. 1 and FIGS. 4 to 6, at least one movable guide member 12 is provided to adjust the vertical direction of the air passing through the ventilation hole 10. In this embodiment, in addition to this movable guide member 12, another movable guide member 112 is provided above the mirror holder 8. These guide members 12, 112 are vertically rotatable between a retracted position shown in solid lines in FIGS. 1, 4, and 5 and an upright position shown in chain lines in these figures. It is supported by a mirror holder 8, and by adjusting the tilt position of the movable guide members 12, 112, the vertical direction of the wind flowing from the front can be freely regulated. That is, if the movable guide members 12 and 112 are brought to the upright position shown by the chain lines, these guide members 1
The wind flowing above No. 2,112 is regulated upward in its flow direction. On the contrary, the guide members 12, 11
If 2 is stored in the storage position shown by the solid line, the wind will flow almost horizontally.

Therefore, when the tall driver P1 is seated, for example, as shown in FIG. 3b, if the movable guide members 12, 112 are brought to the standing position, the wind guided by these It hits the outer surface of the window glass surrounded by the chain line in FIG. Therefore, the driver P1's visibility when looking at the mirror 9 is ensured. In addition, Fig. 3b
The diagonal line also indicates the part where water droplets have adhered (3rd
The same applies to Figure c).

On the other hand, as shown in FIG. 3c, when the short driver P2 is seated particularly at the rear, the movable guide members 12, 1112 are rotated to an appropriate position other than the standing position, and the driver P2 is guided by them. The water droplets in this area are removed by allowing the wind to blow against the area surrounded by the chain line in the figure, that is, the area of the outer surface of the glass below the area shown in the chain line in FIG. 3b. As a result, driver P2
Even when the person looks at the mirror 9, the field of view can be secured.

By rotating the movable guide members 12, 112 and adjusting their tilt positions as described above, the visibility when looking at the mirror 9 is ensured by an occupant of any size and seated in any position. can. Furthermore, when the window glass 11 is opened, by adjusting the inclination of the movable guide members 12 and 112, air can be directed to body parts according to the occupant's preference, allowing the occupant to enjoy a comfortable drive. It is.

Any structure for rotating the movable guide members 12, 112 can be adopted as appropriate, and an example thereof is shown in FIG. In FIG. 4, a motor case 13 is installed in the interior space of the mirror case 7, and the output shaft of a motor 14 housed here passes through the case 13, and a first bevel gear 15 is fixed to the tip thereof. . This gear 15 meshes with second and third bevel gears 18 and 19 fixed to one end of each operating shaft 16 and 17, and fourth and fifth bevel gears fixed to the other end of each operating shaft 16 and 17. Bevel gears 20, 21 are engaged with fifth and sixth bevel gears 24, 25 fixed to one end of each horizontally extending rotating shaft 22, 23. Also, each movable guide member 112, 12 is attached to each rotating shaft 22, 23.
is fixed. 26 and 27 are mirror drive motors for tilting the mirror 19, and these motors are also housed in the motor case 13.

By operating a switch (not shown) provided in the driver's cab, the motor 14 is activated, and its rotation is transmitted to each movable guide member 12, 112 via the aforementioned bevel gear etc., and moves these in the vertical direction. You can rotate it and adjust its tilt.

In the example shown in FIG. 4, the motor 14 is housed in a motor case 13, and the case 13 is waterproofed. Therefore, water does not enter the motor 14, making it possible to prevent its failure.

Even if the movable guide member 112 is omitted, the intended purpose of the present invention can be achieved. Further, the present invention can be widely applied to door mirror devices having a mirror holder that is not separated into a mirror base and a mirror case.

Effects According to the present invention, the vertical direction of the wind passing through the ventilation hole formed in the mirror holder can be adjusted using the movable guide member, so that the driver can easily hold the mirror regardless of the driver's height. It is possible to reliably secure the field of view when viewing.
