Abstract

PURPOSE:To unnecessitate any wiper to thereby improve the field of vision and enhance stability at the time of running at high velocity, by provising a vane form plate in a substantially horizontal or downwardly directed condition above and on the fronst side of a windshield, with a spacing between it and the windshield. CONSTITUTION:The vane form plate 8 in a substantially horizontal or downwardly bent form or in a flat plate form is provided above and on the front side of the windshield 2 of the automobile 1, with a spacing between it and the windshield 2, so that raindrops 6 do not impinge directly on the windshield 2 and the field of vision for driving is maintained to be favorable. By this, an airflow 3 from the front side of the automobile 1 is split into an airflow 9 passing between the windshield 2 and the plate 8 and an airflow 10 on the outside of the plate 8, with the velocity V1 of the airflow 10 higher than the velocity V2 of the airflow 9. Accordingly, vortex flows are prevented from being generated on a roof 4, and running performance is enhanced. In addition, since raindrops are shielded by the vane form plate 8 when it rains, the wiper is unnecessitated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a windshield device for an automobile, etc., characterized in that a wing-like plate is provided above the front of the windshield, with a space therebetween, and extending substantially horizontally or downwardly. Eliminating conventional wipers improves visibility and reduces fuel consumption.

Figure 1 shows a conventional running car, in which airflow (3) hits the windshield (2) from the front of the car (1) and rises.
) does not flow along the surface of the roof (4) and forms a swirl (5), which increases the air resistance of the vehicle body and increases fuel efficiency.
6) falls not only while driving but also when the vehicle is stopped, so rainwater from the windshield must be removed by moving the wiper (7) left and right. This obstructs the driver's field of vision and can lead to traffic accidents. It was something.

In order to eliminate this wiper, attempts were made to treat the windshield surface with water repellent or hydrophilic treatment, but
The vehicle speed is not sufficient to blow away the water film, and the uneven flow of raindrops and water film on the glass surface disrupts the visibility, making it impractical.

The present invention solves all of the conventional problems as described above, and is an epoch-making invention since the beginning of the automatic industry.

Fig. 2 shows an embodiment of the present invention.In order to prevent rain (6) from directly shining on the windshield (2) of an automobile (2) and to maintain the driver's field of view through the windshield, a A substantially horizontal or downwardly curved or flat wing-shaped plate (8) is provided at a distance from the glass. This allows airflow (3) from the front of the car (1).
) is divided into an airflow (9) between the windshield (2) and the airfoil (8) and an airflow (10) outside the airfoil (8), and the flow velocity of the airflow (10) is the airflow The flow velocity becomes faster than the flow velocity V2 of (9), and the swirl that is about to form on the roof (4) is beaten by the airflow (10) and its occurrence is suppressed, so that fuel consumption can be reduced.

In addition, when the car is running at a relatively low speed, and the falling speed of the rain is 3 and the speed of the car is 2 in the vector diagram shown, the rain tries to hit the windshield (2) at a speed of 5, but the wing-like plate (8) and does not hit the windshield (2), thus eliminating the need for a wiper. Of course, an auxiliary wiper may be provided, but in this case, since there is a gap (11) between the wing plate (8) and the windshield (2), the wiper can be provided in this space so as to be able to operate freely. Also,
There is an advantage that when wiping the windshield, you can insert your hand into this gap (11).

Furthermore, when the car is running at high speed, the rain (6)
) was blown backwards, and the rain did not hit the windshield.

The wing plate (8) is made of a transparent, opaque, smoked or colored plastic plate, and as shown in Figure 3, the cross-sectional shapes are a flat plate (12), a downwardly curved plate (13), a Clark Y-shaped cross section (14), and an upwardly curved plate. There are plate (15), reverse Clark Y-shaped cross section (16), etc.

Figure 4A shows an inverted Clark Y-shaped cross section plate (16) as a wing plate.
This is an embodiment of the present invention in which the windshield (2) is provided at the upper front of the windshield (2), and since the flow velocity V+ on the Clark 7 curved surface is greater than the flow velocity Vz on the Clark Y plane, the rain (6) is guided from the front to the rear and is almost horizontal. Since the rain is blown backward through the gap (11), there is no need for wipers to cover the windshield.

Further, due to V and >Vλ, the wing plate (16) is pressed downward, that is, toward the vehicle body, and can be stably supported by the vehicle body, and the vehicle body is held down and the front wheels are pressed against the ground, so the vehicle can run stably.

Further, as shown in Figure 4B, the entire lower surface of the slope (13) is coated with translucent plating (17) so that it can be used as a rearview mirror for use by the driver (18), or it can be curved upward as shown in Figure 4C. Mirror plating (19) can be applied to the half-width rising portion of the plate (15) to form a rearview mirror.

Further, as shown in FIG. 5, a smoked or colored plastic plate (20) can be used also as a sun visor. In this way, the wing plate (8) is conveniently located because it also has other functions.

Figures 6, 7, and 8 show an embodiment of the present invention in which the wing-shaped plate is provided integrally with the vehicle body in advance during the manufacture of the automobile. ) to support the wing plate (8), or attach a U-shaped transparent panel (22) with the wing plate (8) at the top as shown in Figure 7, or extend it from the roof (4) as shown in Figure 8. The arm (23) supports the wing plate (8).

Figure 9 shows an embodiment of the present invention in which the present invention is attached to a ready-made automobile using an adapter.
4), and connect the lower ends of these pillars to the car body's bonnet 7).
It is inserted into the recess of (25), inserted, and fixed with screws, etc.

10 and 11, a mirror (26) inclined approximately 45 degrees forward and/or a mirror (27) inclined approximately 45 degrees rearward is provided on the wing plate (8), and the mirror (
28), and the driver (18) has a mirror (26) (2
This is an embodiment of the present invention in which the front of the vehicle is viewed with the line of sight (29) reflected by the mirror 6-(27) (28), or the rear of the car is viewed with the line of sight (3o) reflected by the mirror 6-(27) (28>). (
27) is located in a high position, so it has a wide field of view and can be viewed like a telescope.

FIG. 12 shows the present invention in which the wing-like plate (8) rotates around the support shaft (31) to change the inclination angle, and the end of the wing-like plate is fixedly supported by the bending arm (32). This is an example.

The present invention has the following many advantages due to the above-mentioned configuration.

(1) It is possible to reduce fuel consumption by reducing the drag coefficient C,) caused by turbulence such as swirls in the airflow surrounding the traveling vehicle body.

(2) Even if it rains when driving at high speeds, the airflow generated by the wing plates will blow the rain away from the windshield, and the airflow generated by the wing plates will blow the rain away from the windshield, preventing rain from adhering to the windshield. In addition, when driving at low speeds, the wing-like plate directly blocks rain from hitting the windshield, eliminating the need for wipers, which were used exclusively in the past, and eliminating the need for anything to obstruct the field of view, ensuring a complete view. Also, since there are no operating parts such as wipers, there is no possibility of failure.

(3) It can also be used as a sun visor, and in particular can completely block sunlight over a wider range and angle than conventional sun visors.

(4) The lower surface can also be used as a rearview mirror, and in this case, the rearview mirror is much wider and easier to see than conventional rearview mirrors.

(5) When equipped with a mirror function, a telescope function can be obtained.

(6) Since the force that presses the wing-like plate downward can be exerted by the airflow when the car is running, the wing-like plate can be stably fixed to the vehicle body.

(7) In the case of the previous item, as the vehicle speed increases, the pressing force of the wing plate attached to the vehicle body becomes stronger, which prevents the front wheels of the vehicle from slipping on the ground, automatically improving high-speed driving performance. improve.

As described above, the present invention eliminates the need for wipers for automobiles, simplifies the structure, improves driving safety, reduces fuel consumption by preventing eddy currents around the vehicle body, and greatly improves the performance of Sanno, Miza, rearview mirrors, telescope functions, and high-speed driving stability. This is a groundbreaking invention that brings about the following effects.

It goes without saying that the present invention includes the wing-shaped plate itself, as well as automobiles, ships, aircraft, etc. provided with the wing-shaped plate.

In addition to the embodiments described above, various modifications are all included in the present invention.
