Abstract

A wiper blade for the wiper of motor-driven vehicle features that the existing single-finger palm-shaped wiper blade is changed into three-finger palm-shaped wiper blade, so opening-type cleaning is changed into enclosed one, preventing the cleaning liquid from being blown to dry, effectively wiping the mosquito and moth on windscreen by wiper in high-speed running, increasing service life of wiper blade by 30% and saving cleaning liquid by more than 20%.

Description

Scraping blade

The utility model relates to the scraping blade on a kind of self-propelled vehicle Windshield Wiper.

Sleet that adheres on the front windshield glass and dirt can influence driver vision, therefore, wind wiper are housed all on the automobile.Windshield Wiper then can influence the sight line of chaufeur in driving if scrape dirt on the clean air regulator, so Windshield Wiper is the automotive safety requisite parts of driving a vehicle.Windshield Wiper exposed parts onboard has scraping arm and Wiper blade, and Wiper blade is divided into two parts again, and the part that contacts with air regulator is the scraping blade made from elastomeric material, and the support scraping blade is support.The existing plate shape of scraping all is to be single fingers and palms shape, and as the 431955425 type Wiper blades that the dynamo-electric factory in your boat group ten thousand river produces, under the effect of the spring on the scraping arm, the head of scraping on the scraping blade tightly is squeezed on the air regulator, is directly undertaking the function that scrapes off dirt on the air regulator.Working specification requires: glass does not use Windshield Wiper under dry situation, in order to avoid damage glass or scraping blade.In addition, if the dirt that will scrape off earlier is moistening, then scraping glass is easier, therefore, the front windshield glass scrubber is housed all on automobile, and it is with a little impounding kettle.Scrubber can to the scraping blade cleansing fluid that ejection on the glass surface of scraping is enough, be referred to as the open type washing in the Windshield Wiper oscillation period.The main chemical compositions of cleansing fluid is a methyl alcohol, and it can dissolve the dirt and the organic matter of glass surface rapidly, helps the timely scraping air regulator of Windshield Wiper, but volatile.Now; because a large amount of constructions of express highway; make the speed of a motor vehicle accelerate, in running at high speed, be sprayed on the cleansing fluid of glass surface; also have little time to dissolve dirt; but can be done by wind very soon, the speed of a motor vehicle dries up also about fast more soon, especially in summer of sweltering heat; when temperature is very high; evaporation of liquid is also very fast, and like this, wind adds evaporation; make not only a large amount of cleansing fluids slattern; cause crucial moment no cleansing fluid to use, but also have a strong impact on clean result, in addition " a flying moth darts into the fire " of meeting through regular meeting in summer; the automobile that a large amount of mosquito moths are run at high speed collides to death on front windshield glass; very fast by air-dry,, under the help that can not get cleansing fluid be difficult to front windshield glass scraping with Windshield Wiper this moment; had a strong impact on traffic safety, made chaufeur have to stop and carry out manual removal.

The purpose of this utility model just provides a kind of scraping blade; the cleansing fluid that it can prevent to be sprayed on the front windshield glass is done or is evaporated by wind, makes it effectively to dissolve dirt, and being convenient to Windshield Wiper can be in galloping; also can the scraping front windshield glass, the protection driver vision is interference-free.

For solving above-mentioned task, technical solution of the present utility model is: will have a both sides of scraping of the scraping blade that is single fingers and palms shape now, and respectively increase one and auxiliaryly scrape head, and make whole scraping blade be three fingers and palms shapes.Two auxiliary main head weak points of scraping of length of scraping head, its shape is basic identical with main scraping blade.Like this, when Wiper blade during to left movement, the main head of scraping is scraped head with left redundant and is contacted with front windshield glass, thereby crosses aquaporin at reverse U shape of square one-tenth on glass, and right redundant is scraped a then perk and left glass surface at this moment; When Wiper blade moved right, the main head of scraping was scraped head with right redundant and is contacted with front windshield glass, also forms a reverse U shape and cross aquaporin above glass, and left redundant is scraped a perk and left glass surface at this moment, like this about repeatedly.Whenever a certain auxiliary head of scraping with main when scraping capitiform and becoming aquaporin, it is main that to scrape head identical with existing single fingers and palms shape to the pressure and the function of front windshield glass, assisting scraping blade then is to be pressed in glass surface gently.

At the middle part of scraping blade, in a water pipe is housed.The water inlet of water pipe is connected by the water route of a flexible pipe and scrubber, and the water outlet of water pipe reaches main narrow neck place of scraping head, crosses aquaporin with the main reverse U shape of scraping a both sides and connects.When Wiper blade during to left movement, main to scrape head crooked to the right, makes the winner scrape the narrow neck place extruding on head the right, force the water outlet closure of right passage, and the water outlet of left passage opened.From the cleansing fluid of scrubber, flow into main head and the left redundant of scraping by water pipe and scrape in the mistake aquaporin that capitiform becomes; When Wiper blade moved right, it is crooked left that the master scrapes head, makes the winner scrape the narrow neck extruding on a left side, force the water outlet closure of left passage, and the water outlet of right passage is opened, and from the cleansing fluid of scrubber, flows into main head and the right redundant of scraping by water pipe and scrapes in the mistake aquaporin that capitiform becomes.Back and forth, the maintenance on glass that will scrape at scraping blade is moistening all the time so.

Adopt the present technique solution; make cleansing fluid enter aquaporin by water pipe; form closed washing; realize zone directly moistening and that the dissolving scraping blade is about to scrape; cleansing fluid has been the protection of aquaporin; avoided drying up and evaporating, not only made the Windshield Wiper mosquito moth on scraping front windshield glass surface timely and effectively, improved 30% in service life of Wiper blade, save cleansing fluid more than 20% but also make.

Describe in detail below in conjunction with accompanying drawing:

Fig. 1 is the assembly figure of existing Wiper blade;

Fig. 2 is a section-drawing of the present utility model;

In Fig. 1, (0) is scraping arm, and (1) is support, and (2) are scraping blades, and (3) are strengthening rib strips, and (4) are to scrape head.

In Fig. 2, (5) are water pipes, and (6) are to assist to scrape head, and (7) are water outlets.At the middle part of water pipe, and fluted with the strengthening rib strip contact position, week is with the constraint water pipe.The installation site of water pipe is at scraping blade and scraping arm termination relative motion smaller part.After cleansing fluid entered aquaporin, under hydraulic pressure, gravity and action of centrifugal force, the glass surface that scraping blade is about to scrape was moistening rapidly.

Claims (2)

1, the scraping blade on a kind of self-propelled vehicle Windshield Wiper, it by strengthening rib strip (3), scrape head (4) and form, it is characterized in that: scrape a both sides main, auxiliary scrape (6) are respectively arranged.

2, scraping blade according to claim 1 is characterized in that: at the middle part of scraping blade, water pipe (5) is installed, the water inlet of water pipe is connected to scrubber, and water outlet passes to the main aquaporin of crossing of scraping a both sides.
