JPS59128035A - Wiping mechanism of windshield for automobile - Google Patents

Abstract

PURPOSE:To enable to wipe effectively a rain drop and dust adhered to a windshield, by a method wherein high pressure air is injected from a nozzle and this high pressure air flow is made to collide against the windshield of an automobile by leading it through a diffusing reflecting plate. CONSTITUTION:A high pressure air flow is injected from an air nozzle 1, which is blown against the surface of a windshield 3 of an automobile by making the high pressure air flow reflect and diffuse through a diffusing reflecting plate 2 of an air leading type and a rain drop and dust sticked to the surface are wiped off. A cloud of the windshield 3 is eliminated by heating the above high pressure air flow appropriately. With this construction, the appropriate field of vision of the windshield can be secured easily.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile windshield wiping mechanism.

Automobile windshield wipers are of the oscillating type, which wipe the surface with a fibre. This is because the bra song effect is certainly rotten, but branon nog is done intermittently.

It is impossible to continuously wipe away the 111 drops that are poured without interruption. If the oscillation period is shortened to make it nearly continuous, the oscillation motion will conversely cause the field of view to be significantly distorted.

The conventional wiping mechanism is not desirable from the standpoint of safe driving.

The present invention was made in view of the above circumstances, and
The purpose is to provide a new wiping mechanism for automobiles that utilizes air pressure.

The mechanism of the present invention basically blows air onto the windshield to destroy raindrops, dust, etc. that have landed on the windshield. Reflect 1. This is an automobile windshield wiping mechanism characterized by comprising an inductive type diffuse reflection plate that is guided, diffused, and collided with the windshield.

Next, the present invention will be explained with reference to the drawings of the machinery building.

FIG. 1 is a schematic diagram for explaining the present invention machine 1'7/7%.

(1) is an air nozzle, and (2) is an air-guide type diffuser reflector that diffuses and blows the high-pressure air flow jetted from (1) onto the wiped surface of the windshield (3).

The airflow ejected from the nozzle (1) is narrowed to some extent by the nozzle hole or slit, so the spray area is limited;
The light is efficiently guided along the surface, diffused and reflected, and collides with the windshield wiper surface. The reflector has two functions: reflecting airflow and guiding diffusion.

It is desirable that the pressure of the airflow colliding with the front surface be uniform throughout, so in order to avoid this, the gap between the nozzles,
Angle, Air pressure 1 Angle of anti-sealing plate (Flo/To glass and 6
)1 curvature etc. can be changed as appropriate. If necessary, these Konotro-11 mechanisms can be made into a mechanism that can be operated automatically inside the vehicle.

High-pressure air is generated by a compressor (not shown in Figure 9). The power for this tank can be sufficiently provided by diversion of engine power. It is also necessary to provide an appropriate filter at the air intake port to prevent the windshield 4D from being scratched by dust in the air.

If the windshield is heavily soiled, the jet nozzle may be provided with a switching function to jet the cleaning water as appropriate.

Another feature of the present invention is that fogging of the windshield can be eliminated by heating the air blown. When there are large differences in temperature and humidity between the inside and outside of a car, visibility becomes poor due to fogging on the glass, but this can be resolved by heating the air.

Figure 2 schematically shows the state of wiping the glass surface when the present invention is installed in pairs on the left and right sides of the windshield at the bottom. The area indicated by the 9-dotted line is thereby wiped out.

Unlike conventional methods, the present invention utilizes air to remove raindrops and dust, and no matter how heavy the rain, a clear γ+rI field of view can always be ensured.

It has a unique feature that can also solve the problem of clouds on the windshield.
