|The downforce on which the wiper blade is bonded to the glass will be sharply lost when the wiper is scraped back, and may not even fit well on the glass surface. Under such a high airflow, the movement of the wiper becomes very unstable. Due to the inclination of the glass, the wiper is only like a downwind when scraping upwards, and the wiper blade is easy to scrape, and the downward scraping is due to The effect of wind resistance on the wiper blade will make the movement difficult. In severe cases, the wiper blade is blown away from the glass due to the lift of the airflow and does not work properly.|
It is generally stipulated that the design of the wiper needs to take into account the influence of the airlift lift. Different scraper blade shapes and body design will affect the airlifting force. In general, the boneless blade has a significant increase in aerodynamic performance due to the special spoiler shape. Compared to bone scrapers, boneless scrapers are less likely to be blown up.
In order to improve the ability of the bone wiper to resist air lift, an anti-fog can be added to the bone wiper. The windward side of the flutter protects the airflow from a downward force, allowing the wiper to withstand greater wind.
