Description

Blades for Car Wipers

The present invention relates to a blade for an automobile wiper, and more particularly, to an improved blade for cleaning the windshield to reduce waste of washer liquid.

The wiper of the car removes the windshield (front window) or the rear window (hereinafter referred to as the windshield) when the car gets wet due to the snow, and removes it for safe visibility. It is a device that sprays the washer liquid to the foreign matter on the shield to secure a clear view.

The wiper is composed of a link mechanism connected to the wiper motor and a blade which is connected to the end of the link mechanism and the wiper arm angular movement and connected to the windshield to remove water and foreign matter directly.

The blade is composed of rubber material, which is directly connected to the windshield to remove water and foreign matters, and a support that supports the edge by forming a plurality of protrusions on both sides from above the edge. It is a configuration that is accommodated in the packing consisting of coupled by the bridge connected to the wiper arm.

Conventionally, since the blade has a single edge and the washer liquid is concentrated in one place, it has a problem such as that the water or foreign matter on the windshield cannot be removed smoothly.

Especially when the washer fluid is sprayed to remove foreign substances on the windshield on a clear day, the washer fluid is sprayed only to a certain position from the bottom of the windshield (cover between the hood panel or hood panel and the windshield). The washer fluid is distributed throughout the windshield by the angularly moving blade.

However, the sprayed washer liquid is not evenly distributed throughout the windshield by one wiping operation, and thus, the sprayed washer liquid is scattered to the windshield as well as the roof panel and the rear window to contaminate the vehicle. And washer fluid is wasted unnecessarily.

Therefore, in the present invention, the blades are designed to solve the above problems, and the blades are provided with a plurality of edges and the blades can be directly supplied between the plurality of edges to smoothly clean the windshield even with a small amount of washer fluid. Its purpose is to provide ease of performance and visibility, and to prevent waste of washer fluid.

Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

Sectional view along the line BB of Figure 2, Figure 5 will be described together as a state diagram of use of the present invention.

When the windshield of the car is wet due to the snow or foreign matters, the wiper 10, which serves to remove it for securing a safe field of view, is connected to the link mechanism receiving the power of the wiper motor, and the wiper moves angularly. The arm 11 is connected.

A bridge 13 is connected to the wiper arm 11, and the bridge 13 is coupled to a pad 12 accommodating a blade 16 made of rubber material formed of an edge 14 and a support 15. Configuration.

In the related art, since the blade 16 has a single edge 14 and the washer liquid is injected below the windshield, it is not possible to smoothly remove the moisture or foreign matter from the windshield, thereby preventing a clean front view. Of course, there is a problem described above such that unnecessary washer liquid is wasted.

Considering the above problems, the blade 16 to which the technique of the present invention is applied is shown in FIGS. 2 to 4, which will be described in detail as follows.

The blade 16 of the present invention protrudes a plurality of edges 14 on both sides under one support 15 having a wider width, and a nozzle receiving hole for spraying washer liquid between the edge 14 and the edge 14. (20,21) are formed in many places at equal intervals.

The nozzle accommodation holes (20, 21) is in communication with the nozzle pipe inlet groove 22 formed to be recessed in the upper surface of the support (15), the nozzle accommodation holes (20, 21) and the nozzle pipe inlet groove 22 in the washer fluid tank In the nozzle tube body 26 is connected to the washer liquid pipe 23 extending through the bottom of the wiper arm 11 and composed of a plurality of nozzles 24 and a nozzle tube 25 connecting them.

It is preferable to form a plurality of uneven protrusions 27 and 28 in order to prevent the end of the nozzle 24 constituting the nozzle body 26 from being easily separated from the nozzle accommodation holes 20 and 21.

According to the present invention configured as described above, since the edges 14 of the blades 16 are formed in plural, when the wiper 10 operates in rainy weather, the blades 16 reciprocate to remove moisture from the windshield. (16) After the primary water is removed by the leading edge 14 during the reciprocating motion, the rear edge 14 smoothly removes the remaining water, thereby easily securing the forward clock.

In addition, when the washer fluid is sprayed to remove foreign matters on the windshield in the clear weather without rain, the washer fluid pipe 23 extending from the washer fluid tank to the blade 16 through the bottom of the wiper arm 11 is a blade. The washer liquid is supplied to the nozzle tube 26 condensed on (16).

The nozzle body 26 supplied with the washer fluid sprays the washer fluid through the nozzles 24 press-fitted between the edges 14 and the edges 14 formed on the both sides under the support 15 and the blades 16. Pinging is performed more smoothly, and unnecessary waste of washer liquid can be prevented.

The present invention as described above has the effect of preventing unnecessary waste of washer liquid by spraying the washer liquid in the necessary place, and forming a plurality of edges to facilitate the removal of foreign substances as well as moisture, thereby ensuring a forward clock. .
