Description

[Detailed Description of the Invention] The present invention relates to a rectifier plate that controls airflow hitting the windshield of an automobile or the like.

Normally, in a car, especially a passenger car type car, the airflow 2 during driving is generally in the state shown in FIG. 1 A and B due to the angle and curved shape of the windshield 1. Therefore, when the wiper 3 has a wiping pattern X, X' as shown in the figure, the portion P where the airflow 2 and the wiper 3 intersect at right angles is likely to receive lift, and therefore, the wiper 3 floats during high-speed operation. There is a problem that the wiping performance deteriorates. Therefore, conventionally, in automobiles that run at extremely high speeds such as racing cars, a rectifier plate 5 is provided on the hood 4 of the vehicle body below the windshield 1, as shown in FIG. An air curtain is formed by flowing upward to prevent the wiper 3 from floating, improving wiping performance and preventing the adhesion of mud, insects, etc., but it is not widely used because it obstructs visibility. .

The present invention was devised in view of the above-mentioned conventional problems, and does not impede forward visibility during normal driving without using wipers.
The purpose of this invention is to reduce the lift force exerted on the wiper blade when the wiper is used during rain, thereby improving the wiping performance.

Therefore, in this invention, the wiper blade
Provided on a vehicle having a wiper device stored in a storage position below the lower inverted position during wiping operation, a rectifying plate body is provided below the windshield of the vehicle and in a part of the vehicle body in front of the windshield. The base end of the rectifier plate is pivoted, and the rectifying plate body is rotatable from an upright position in which it stands upwards to a stored state in which the tip of the rectifier plate body contacts the windshield, and is rotated by a spring in the stowed state. The base end of the stay, which is biased in the direction of the current plate and can be folded into the current plate body, is pivotally supported near the tip of the current plate body, and between the current plate main body and the stay, there is a structure in which the stay is in an upright state. A stopper is provided that comes into contact with the
The stay is urged by a spring in the direction of the upright state, and further, in the upright state of the stay, the tip of the stay abuts the windshield between the lower reversed position and the retracted position of the wiper blade. The purpose of the present invention is to achieve the intended purpose by providing a rectifying plate for a vehicle that is designed to have the following characteristics.

The present invention will be described below with reference to illustrative embodiments.

A is a concealed type wiper device having a rise-up function, and is composed of a wiper blade 11, a blade stay 12, a fin 13, etc. When the wiper device a is not in use, the wiper blade 11 moves downward during wiping operation. It is designed to be stored between the lower end of the windshield 14 below the side reversal position and the hood panel 15 of the vehicle.

Reference numeral b denotes a current plate, which is composed of a current plate main body 16 and a stay 17.

The base end 16a of the current plate main body 16 is located below the windshield 14 and
The hood panel 1 is a part of the front vehicle body of 4.
The current plate main body 16 is rotatably supported inside the end edge of the current plate 16 via a support shaft 18, and when the current plate main body 16 is in an upwardly erect state, the tip 16b of the current current plate main body 16 touches the windshield 14. It can be rotated to the stored state where it touches. Furthermore, a spring 19 is interposed in the support shaft 18 to bias the current plate main body 16 in the direction of the stored state, and is configured to urge the tip 16b of the current current plate main body 16 toward the windshield 14. There is.

The base end 17a of the stay 17 is rotatably supported on the inner surface near the tip 16b of the current plate main body 16 via a support shaft 21, and is foldable on the inner surface of the current plate main body 16. . moreover,
A spring 22 with a relatively strong spring force that biases the stay 17 in the direction of the upright state is interposed on the support shaft 21, and when the stay 17 is in the upright state, the tip 17b of the stay 17 is connected to the wiper. The current plate main body 1 is brought into contact with the windshield 14 between the lower inverted position and the retracted position of the blade 11.
6 is supported so as to be substantially parallel to the windshield 14.

Reference numeral 20 denotes a stopper for holding the stay 17 in an upright state. In the embodiment, the stopper 20 is provided protruding from the inner surface near the tip 16b of the current plate main body 16, so that the stay 17 is held in the upright state. Although the stopper 20 is brought into contact with the outer surface near the base end 17a, the stopper 20 is provided to protrude from the outer surface near the base end 17a of the stay 17, and when the stay 17 is in the upright state, the tip 16b of the current plate main body 16 It may be made to come into contact with the inner surface of the.

Now, when the wiping operation of the wiper device a is stopped, the fins 13 of the wiper device a push the stay 17 of the rectifying plate b, folding the stay 17 against the spring force of the spring 22, and the wiper device The wiper blade 11 of a is stored between the windshield 14 and the hood panel 15, and the current plate b is housed between the current plate main body 16 and the stay 17.
The folded state is stored between the windshield 14 and the hood panel 15 by the spring force of the spring 19. (See Figure 4) When the wiper switch (not shown) is turned on to operate the wiper device a from the above state,
The wiper blade 11 of the wiper device a rises from the storage position to the lower inverted position during the wiping operation shown in FIG.
Since the current plate b slides while pressing the outer surface of the current plate b, the current plate b is pushed up against the spring force of the spring 19. Then, the top part 13a of the fin 13 is connected to the stay 1.
7, the stay 17 rotates in the opening direction around the support shaft 21 due to the spring force of the spring 23, and its tip 17b abuts the windshield 14 surface, and furthermore, The rectifying plate body 16 is supported substantially parallel to the surface of the windshield 14, and the rectifying plate b is automatically set.

In the above embodiment, the fins for undulating the rectifying plate b were formed into a substantially inverted V shape for illustration purposes;
The shape is not limited and may be any suitable shape, or the fins may be eliminated and the blade stay 12 may be used instead. Another possible method of operation is to use a drive device such as a motor, solenoid valve, or air cylinder, but this is not preferable because the structure will be complicated, the number of parts will increase, and the product will be expensive. .

As described above, according to the present invention, a rectifying plate for adjusting wind pressure, etc. is rotatably mounted between the lower part of the windshield and the vehicle body, and is installed at a predetermined position only when the wiper device is in operation. When in use, it is stored between the windshield and the vehicle body, so the forward visibility is not obstructed during normal driving without the wiper device in use, and when the wiper is in use during rain, etc., the rectifier plate By creating an air curtain in front of the windshield surface, it is possible to decelerate the airflow on the windshield surface, reduce the lift force exerted on the wiper blade, and improve the wiping performance, allowing comfortable driving. Further, according to the present invention, since the current plate is automatically operated by the rise-up mechanism of the wiper, the structure is simple and can be provided at low cost.
