Description

  The present invention relates to a vehicle side mirror that is attached to the outside of a vehicle such as an automobile or a truck, and relates to a raindrop removing device for a vehicle side mirror with good visibility that can easily check the back even in rainy weather. .

In general, vehicles such as automobiles and trucks are equipped with a rearview mirror that is attached to the inside of the vehicle and side mirrors that are attached to the left and right sides of the vehicle (for example, door mirrors, fender mirrors, etc.). Since the rearview mirror is mounted inside the vehicle, it is not affected by the outside air environment, but the side mirror is mounted outside the vehicle, so it is easily affected by the outside air environment, especially when driving in rainy weather. , Raindrops are attached to the side mirror, making it difficult to check backwards.
If these raindrops adhere to the side mirror, the visibility is poor even during daytime running, and even more difficult at night.

  Various inventions have been proposed for such problems. For example, in Japanese Patent Application Laid-Open No. 11-151979, an inclined portion inclined in the traveling direction is attached to the upper portion of the side mirror, the wind taken along the inclined portion is reversed, and the wind in the opposite traveling direction is applied to the mirror surface. An invention is provided in which water droplets adhering to the mirror surface are removed by wind pressure.

  JP-A-2006-36111 discloses that a raindrop removal device can be mounted on the peripheral wall above the side mirror, takes in the wind generated by the running of the vehicle, and reverses the wind taken in the same way as in the prior art, There has been provided an invention in which the wind is blown to the mirror surface and water droplets attached to the mirror surface are allowed to flow down.

Japanese Patent Laid-Open No. 11-151979 JP 2006-36111 A

In the case of the raindrop removal apparatus as described above, winds caused by wind pressure during traveling (hereinafter referred to as “traveling wind”) are always blown onto the mirror surface when the vehicle travels, regardless of whether it is sunny or rainy. That is, in all cases, the intake port for taking in the traveling wind generated when the vehicle is running is always open, and if the vehicle travels, the traveling wind from the intake port, regardless of the weather, whether it is sunny or rainy. Will always be captured. Therefore, if the wind blows strongly and dust is mixed, or if you run in an environment where yellow sand flies and dust is mixed, the dust and sand may collide with the mirror and damage the mirror surface. There is. In addition, when the insects run during the spring season, small insects are taken in, and the insects collide with the mirror surface of the side mirror and stain the mirror surface, which in turn deteriorates visibility.
In addition, all raindrop removal devices are the same, but because it is structured to blow the traveling wind to the mirror surface of the side mirror by reversing the traveling wind, dust, sand dust and insects taken in from the traveling wind intake are It stays in the reverse part, and the flow of the traveling wind is worsened.
In addition, since the captured traveling wind is reversed, the air resistance is increased, the traveling performance is deteriorated, and the flow of the traveling wind gives vibration to the side mirror, thereby deteriorating the visibility.

In recent years, most of the side mirrors are installed in doors, and the side mirrors can be seen through the door windows, and raindrops attached to the door windows have deteriorated the visibility. . Some vehicle owners are equipped with a door visor at the top of the door frame. When this door visor is equipped, the door visor is attached to the outside of the vehicle body, so that wind generated during traveling by the door visor is blown out to the outside of the vehicle body. As a result, the door window portion in front of the door window, particularly near the side mirror that must be seen through the window, becomes negative pressure, and raindrops are likely to adhere to the door window. When raindrops adhere to the door window, the visibility deteriorates further due to the synergistic action with the raindrops attached to the side mirror.
An object of the present invention is to solve the above-mentioned various problems and to provide a raindrop removal device for a vehicle side mirror that has good visibility even in rainy weather.

The present invention is mounted on a peripheral wall of a side mirror in a vehicle such as an automobile or a truck, and takes in a running wind from vehicle traveling, an outlet that reverses the running wind and blows it to a mirror surface of the side mirror, and these inlets. A ventilation path connecting the outlet and an opening / closing valve at the inlet, and opening the opening / closing valve allows the running wind taken from the inlet to blow out the raindrops adhering to the mirror surface of the side mirror. A raindrop removing device for a side mirror for a vehicle, wherein the raindrop removing device is characterized by being blown away.
The present invention is attached to a peripheral wall of a side mirror in a vehicle such as an automobile or a truck, and takes in an intake for taking in a running wind from running of the vehicle, an outlet for allowing the running wind to pass through, and a side mirror by inverting the running wind. A discharge port that blows on the mirror surface, a ventilation path that connects the intake port to the discharge port and the discharge port, and an open / close valve in the vicinity of the discharge port and the discharge port, and opens the open / close valve from the intake port. The vehicle is characterized in that the taken-in traveling air is blown out from the discharge port, and the opening / closing valve is closed to blow out the raindrops adhering to the side mirror mirror surface from the discharge port. This is a raindrop removal device for a side mirror.

Further, a partition wall is formed in the ventilation path, the traveling wind flowing in the ventilation path is branched by the partition wall, a part of the traveling wind is blown to the door window, and the remaining part is blown to the mirror surface of the side mirror. A raindrop removal device for a vehicle side mirror.
In addition, the on-off valve is driven to open and close in conjunction with the wiper drive, or the on-off valve drive switch is mounted on the in-vehicle instrument panel to open and close the on-off valve. This is a raindrop removing device for a vehicle side mirror.

According to the first aspect of the present invention, an opening / closing valve is provided at the intake of the traveling wind, and the opening / closing valve can be opened / closed by opening / closing the opening / closing valve. By opening the open / close valve, air flow is introduced from the intake port to send the wind to the mirror surface of the side mirror, and the raindrops attached to the mirror surface are blown off. By closing the valve and closing the intake port, it is possible to prevent dust and insects from entering through the intake port, so that the mirror surface of the side mirror is not damaged or the mirror surface is not soiled.
In addition, since the intake is opened only when it rains, even if dust or insects accumulate in the reversing part of the raindrop removal device, it can be washed away with rainwater that has entered from the intake, and the inside of the ventilation path can be kept clean. .
When driving in fine weather, closing the intake allows the driving wind to flow along the outer periphery of the raindrop removal device, so the air resistance caused by the reversal of the driving wind can be significantly reduced and the side mirrors vibrate. There is no influence such as letting.

  In addition, according to the invention of claim 2, of course, the above-mentioned effect is obtained. However, the on-off valve is provided in the vicinity of the discharge port and the discharge port, and the on-off valve is opened when the weather is fine. Since the driving wind taken in from the entrance is blown out from the discharge port, the air resistance is further reduced, and when it rains, it is closed and the driving wind is introduced into the discharge port, and the driving wind is sent to the mirror surface of the side mirror, Raindrops adhering to the mirror surface can be blown off, and the visibility of the side mirror can always be significantly improved.

According to the third aspect of the present invention, the partition wall is formed in the ventilation path, the traveling wind flowing in the ventilation path is branched, a part of the traveling wind is blown to the door window, and the remainder is blown to the side mirror mirror surface. Both the raindrops attached to the door window and the mirror surface of the side mirror can be blown away, and the visibility of the side mirror seen through the door window can be remarkably improved.
According to the invention of claim 4, if the opening and closing of the wind intake is linked to the driving of the wiper, the intake of the raindrop removal device can be opened and closed together with the operation of the wiper. , Without forgetting to close the intake, it is easy to check the back and can run comfortably.
Moreover, since the opening / closing valve can be operated in the vehicle by installing a switch in the vehicle such as an instrument panel, the same effect can be obtained.

The best mode of a raindrop removing device for a vehicle side mirror according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a sectional side view showing the best mode of a raindrop removing device for a vehicle side mirror according to the present invention. In the figure, reference numeral 1 denotes a side mirror. The side mirror 1 has a mirror housing 2, and a power unit 3 is provided in the mirror housing 2 so that the mirror unit 4 can be tilted up and down and left and right by a tilting device. Yes.

The part of is opened.
The mirror unit 4 includes a mirror 41 having a mirror surface and a mirror holder 42 that holds the mirror 41, and the mirror holder 42 is attached to the power unit 3 so as to be tiltable. By driving the mirror holder 42 by the power unit 3, the mirror surface of the mirror 41 can be tilted vertically and horizontally at the opening of the mirror housing 2.
Note that other configurations relating to the side mirror are not related to the gist of the present invention, and thus detailed description thereof is omitted.

Reference numeral 5 denotes a raindrop removing device. The raindrop removing device 5 is formed in a flat and substantially box-like shape, and is attached to a peripheral wall on the upper side of the side mirror 1, and an air passage 6 is formed inside. An intake 7 for the traveling wind 12 is opened at the tip (vehicle traveling direction side) of the raindrop removing device 5, and an opening / closing valve 10 that opens and closes the intake 7 is connected to the side wall of the raindrop removing device 5. It is pivotally supported. The rear end (mirror unit 4 side) is formed in an arc shape to form a reversing portion 8, and a discharge port 9 is opened facing the mirror unit 4. The intake 7 from the intake 7 to the discharge 9 of the traveling wind 12 is connected by the ventilation path 6. When the traveling wind 12 is introduced from the intake port 7 equipped in the raindrop removal device 5 by the traveling of the vehicle, the traveling wind 12 flows along the ventilation path 6 as shown in FIG. As indicated by the arrows, the reversing unit 8 inverts the mirror unit 4 in the direction of the mirror unit 4, blows out from the discharge port 9 formed at the rear end of the raindrop removing device 5, and blows onto the mirror surface of the mirror 41. The raindrops adhering to the mirror surface of the mirror 41 are blown off by the wind pressure and always maintain a clean surface.
The raindrop removing device 5 may be directly fixed to the mirror housing 2, or the raindrop removing device 5 is divided into a main body and a base, and the base is fixed to the mirror housing 2 on the upper peripheral wall of the side mirror 1, The air passage 6 may be formed integrally by fitting the main body to the base.
Needless to say, the shape of the reversing portion 8 is not limited to the arc shape shown in the present embodiment, but may be formed by bending it into a reverse or U shape. In this embodiment, the discharge port 9 is simply opened. However, if the discharge port 9 is formed in a nozzle shape, the pressure at which the traveling wind 12 blows out can be increased, and raindrops attached to the mirror surface of the mirror 41 are removed. It goes without saying that the effect of doing this is further improved.

FIG. 2 is a perspective view showing a rotating cylindrical on-off valve 10 that is pivotally supported by the intake port 7 of the raindrop removing device 5. As shown in the figure, a cylindrical on-off valve 10 is pivotally supported at the intake port 7 on the side wall of a raindrop removal device 5 indicated by a one-dot chain line.
