[0028] best practice
[0029] figure 1 with 2 It is a top view and a side view of a wiper with a windshield according to an exemplary embodiment of the present invention. In these figures, the windshield wiper 10 of the present invention includes a main fork arm 12, an auxiliary rod 14, a plurality of fork brackets 16, and a rubber blade 18. The connector that the arm is connected, the auxiliary rod 14 is pivotally supported on two opposite ends of the main fork arm, and each fork 16 is pivotally supported on one end or two opposite ends of the auxiliary rod 14 place, and there are jaws, and the rubber scraper 18 is clamped by the jaws, and the rubber scraper 18 is used to wipe glass surfaces 20 such as windshields (see image 3 ). In addition, the wiper also includes a windshield 22 arranged in front of the airflow of the main fork arm 12 .
[0030] The wind deflector 22 is pressed, for example, in order to be integral with the above-mentioned main wishbone 12 , and the ...

A wiper blade (10) for use in motor vehicles is provided, which comprises a wind deflector (22) which is provided in front of an air stream and supported in position on a main yoke through a support of reduced width support, wherein the wiper blade comprises said wind deflector which has been formed to have such a configuration in its cross section in which it consists of a plate-like pressure-receiving surface section (28) which is provided along the air stream so as to generate downward forces, an air stream-weir section (30) which is provided to extend from the rear end of the pressure-receiving surface section so as to reduce a velocity of the air stream, and an air stream-splitting section (26) which extends downwardly from the end of the pressure-receiving surface section so as to form a water-weir section below the pressure-receiving surface section, and a distance (H) between the lower edge of said air stream-splitting section (26) of the wind deflector (22) and the shield glass (20) is greater than the height (h) of the blade rubber (18), whereas there may be such a relationship between this height (H) and a clearance (S) to be formed between the upper end of said air stream-weir (30) of the wind deflector (22) and the main yoke (12) as; 1>(S / H)> / =(1 / 5).
Description
technical field [0001] The invention relates to a wiper for automobiles, in particular to a device which can effectively suppress the performance reduction of the wiper due to wind pressure and other factors when the automobile is running at high speed, and is used to significantly improve the wiper performance. device for aerodynamic characteristics. Background technique [0002] In order to suppress the reduction of the wiping performance of the car wiper due to the wind pressure at high speed, many devices have been used. The various devices used are listed below: a device with a blade-like blade, a device that generates part of the downward wind pressure by forming a portion of a rod on a blade-like profile, a device that includes a windshield The device of the board and a part, the wind deflector shown is used to protect the air flow impinging on the rubber blade, the distance between the lower surface of the wind deflector on the said part and the glass surface is det...
