TECHNICAL FIELD OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiper device for an automobile, and more particularly, to a wiper device installed on both sides of a window glass to remove air resistance and sweep down rainwater or foreign matter from above. will be.

[Prior art]

As is well known, the wiper device of an automobile is a device that secures the driver's view by wiping the window glass surface that is dirty due to rain or foreign matter while driving.

Conventionally known structures of such wiper devices are shown in FIGS. 1 and 2.

A wiper 2 is installed on the cowl grill at the lower part of the front of the window glass 1 of the vehicle, and the wiper 2 moves to remain in contact with the window glass 1 and wipes rain water or foreign matter, and It consists of a wiper arm that supports the blade and is pivotally driven by a motor. Moreover, the nozzle which sprays washer liquid is provided in the arbitrary position of the said cowl grill.

Such a wiper device operates the wiper 2 while spraying the washer liquid when the surface of the window glass 1 is dirty, and operates only the wiper 2 when rainwater flows down, thereby securing a driver's front view.

[Technical problem to be achieved]

The above-mentioned conventional wiper pivots upward while being installed in a horizontal state on the lower side of the window glass, and sweeps up foreign matter or rainwater. By this action, foreign matter or rainwater collects in the part visible to the driver's eyes. There is a problem that is difficult to secure visibility.

In addition, the wiper provided in the horizontal direction in the window glass obstructs the flow of air, which is the main cause of the generation of wind noise during high-speed running of the vehicle.

In addition, the spraying of the washer liquid hits the wiper arm or the blade to prevent uniform spraying.

The present invention has been made to solve the problems of the prior art, the present invention is to collect rain water or foreign matter to the bottom of the window glass to ensure a clean view of the driver, improve the structure to block the flow of air wind It suppresses the occurrence of noise and enables uniform spraying of the washer liquid.

[Configuration and Function of Invention]

As a means for realizing the above object, the wiper device of a motor vehicle according to the present invention includes a blade which contacts the window glass and wipes its surface, and a wiper arm that supports the blade and is pivotally driven by a motor.

Subsequently, the blade is installed by the wiper arm in a state parallel to both side edges of the window glass, and is driven from the top to the bottom by the driving of the motor, and sweeps off the foreign matter or rain water to collect the window glass below.

Accordingly, the wiper device sweeps down rainwater or foreign matter on the upper side of the window glass that obstructs the driver's field of view. In addition, the wiper blade is installed long in the air flow direction, it is possible to prevent wind noise due to air resistance.

In addition, since the spray nozzle of the washer liquid is formed in the cowl panel between the wipers disposed on both sides of the window glass, interference with the blade and the wiper arm generated during spraying can be prevented, thereby achieving uniform spraying of the washer liquid.

EXAMPLE

EMBODIMENT OF THE INVENTION Hereinafter, the preferred embodiment for implementing this invention is demonstrated in detail based on an accompanying drawing.

3 is a perspective view showing the wiper device of the vehicle according to this embodiment, which is a perspective view seen from the front side of the vehicle body, and FIG. 4 is a sectional view showing the B-B line of FIG.

In describing this embodiment, the same reference numerals are used for the same structure of the present invention as the drawings cited in the prior art, and will not be described again for the sake of clarity.

Reference numeral 1 in the drawings refers to the front window glass mounted to the vehicle body. In addition, reference numeral 2 refers to the entire wiper.

Unlike the prior art, the wiper 2 according to this embodiment is provided in a state where it is open to both sides of the window glass 1.

More specifically, the wiper 2 is composed of a blade 4 in contact with the window glass 1 to wipe its surface, and a wiper arm 3 supporting the blade 4 and rotated by a motor. ; The blade 4 is installed so as to be parallel to both side edges of the window glass (1).

The wiper 2 is pivotally driven from the top of the window glass 1 to the bottom by the driving of a motor (not shown).

The washer liquid injection nozzles 5 are installed on the front cowl panel of the window glass 1 at equal intervals between the two side wipers 2.

According to this configuration, the wiper 2 is pivotally driven from the upper side to the lower side by the motor while sweeping the foreign matter, rain water or washer fluid toward the lower edge of the window glass 1 to correspond to the driver's eye height. You can keep your view clear.

In addition, the wiper blade 4 is installed long in the air flow direction, it is possible to remove the air resistance generated by the conventional blade, thereby suppressing the generation of wind noise.

In addition, since the washer liquid sprayed by the injection nozzle 5 is prevented from interfering with the wiper 2, uniform spraying can be realized.

[Effects of the Invention]

Through the embodiments described above, it can be seen that the wiper device of the vehicle according to the present invention substantially solves the problems of the prior art.

That is, this invention collects and removes rain water and foreign substances to the lower side of a window or glass, and there exists an advantage which is advantageous in ensuring the driver's view. By removing the air resistance by the blades, the generation of wind noise can be minimized, and uniform spraying of the washer liquid is realized.

On the other hand, while the present invention has been shown and described with respect to specific preferred embodiments, this invention is not limited to the above-described embodiments, the invention belongs without departing from the gist of the invention claimed in the claims. Anyone of ordinary skill in the art will be able to implement various modifications.
