DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small and lightweight water droplet removing device capable of sufficiently removing water droplets attached to a door mirror of a vehicle such as an automobile.

[0002]

2. Description of the Related Art In a passenger car equipped with a front door mirror, a blower is provided in an engine room, a nozzle for blowing air to the door mirror is provided, and a blowout port of the blower and a base end of the nozzle communicate with each other. Water drop removing device communicated via a pipe (Japanese Patent Laid-Open No. 58-61047)
Publication).

A water accumulator tank and an air compressor are provided in a trunk room at the rear of the vehicle body, and a water droplet removing device (Japanese Utility Model Application Laid-Open Publication No. Heisei 4 (1996) -1992) is provided in which the accumulator tank and a base end of a nozzle for blowing a door mirror are connected by a hose. -69364).

[0004]

Among the above-mentioned conventional water drop removing apparatuses, the former water drop removing apparatus ejects air from a nozzle to form an air film called an air curtain on a mirror surface of a door mirror. Although water droplets are prevented from adhering to the mirror surface of the door mirror, a large amount of air cannot be supplied to the mirror surface of the door mirror because the supply tube that connects the pressure accumulator and the nozzle is thin, and water droplets adhere to the mirror surface of the door mirror beforehand. Can not be stopped,
Moreover, it was almost impossible to remove water droplets once attached to the mirror surface of the door mirror.

In the latter water drop removing device, high pressure air in the pressure storage tank can be blown to the mirror surface of the door mirror vigorously, so that water droplets on the mirror surface of the door mirror can be removed. And the distance between the nozzle of the door mirror and the
The air resistance in the hose was increased, and as a result, the air pressure drop in the hose became large, and the pressure of the filling air in the accumulator tank was increased. Further, since a large-sized pressure storage tank is separately required, an increase in vehicle body weight cannot be avoided.

[0006]

SUMMARY OF THE INVENTION The present invention relates to an improvement of a water droplet removing device for a vehicle which solves such a problem, and blows air supplied from an air supply means to a door mirror to adhere to the mirror surface. In the water droplet removing device for a vehicle that blows out the dropped water droplets, the air supply means includes an air compressor, a pressure accumulator for storing high-pressure air pressurized by the air compressor, and air blowing from the pressure accumulator to the door mirror. It is provided with a valve interposed in a ventilation path up to a mouth to openably close the ventilation path, and the pressure accumulator is constituted by a hollow sealed impact beam for reinforcing a door.

[0007] Since the present invention is configured as described above, the valve in the ventilation path from the accumulator to the air outlet to the door mirror is closed, and the air compressor is operated to operate the accumulator. After filling the inside with high-pressure air, if the valve is opened, high-pressure air is blown out from the air outlet toward the mirror surface of the door mirror, and water droplets attached to the door mirror mirror surface are blown off. Can be removed.

In the case of this air blowing, since high-pressure air blows vigorously onto the mirror surface of the door mirror, water droplets on the mirror surface of the door mirror can be sufficiently removed.

In addition, since the door mirror and the pressure accumulator formed by the impact beam in the door are close to each other, the distance from the pressure accumulator to the air outlet is reduced, and the ventilation from the pressure accumulator to the air outlet is reduced. The pressure drop in the road is reduced,
As a result, the charging pressure of the pressure accumulator is reduced, and the pressure accumulator is reduced in size, and there is no fear of air leaking from the pressure accumulator to the air outlet.

Further, since the pressure accumulator is formed of a hollow space impact beam, it is not necessary to separately prepare a pressure accumulator, and the weight and cost of the vehicle can be reduced.

The impact beam 13 for increasing the strength and rigidity of the door body 3 of the front door 2, particularly the strength and rigidity with respect to the body-side direction force, is formed by airtightly fitting caps 15 to both ends of a hollow pipe 14. It is configured as a pressure accumulator having a hollow hermetic structure, and as shown in FIG.
