Abstract
The invention provides a double-blade windshield wiper bar and a manufacturing method thereof. The manufacturing method comprises a hot-press forming step, a cutting step, a folding step and a bonding step which is preferably added. In the hot-press forming step, a rubber sheet is pressed into a rubber product which comprises a plurality of connective windshield wiper bars and a plurality of kinked guiding grooves. In the cutting step, the rubber product is cut into a plurality of independent windshield wiper bars so that each independent windshield wiper bar is provided with a pair of blades which are opposite in the extending direction. In the folding step, all the independent windshield wiper bars are folded along the kinked guiding grooves so that the blades, which are opposite in the extending direction, are parallel to each other. Preferably, by utilizing the bonding step, the folded windshield wiper bars can be permanently set so that the more durable double-blade windshield wiper bars are formed.
Description
Technical field
The present invention relates to a kind of pair of scraping blade rain brush bar and method for making thereof, refer to make a kind of integrated pair of scraping blade rain brush bar especially, via hot-forming, cut apart, amount to and step such as bonding, make it to produce a pair of rain brush scraping blade parallel to each other.
Background technology
Windshield on the vehicle normally utilizes Wiper arm to drive the rain brush group and scrapes in the mode of back and forth wiping away and cleaned, its rain brush group comprise Wiper strip carrier and rain brush bar both.The rain brush bar of rubber system still is considered to be adapted at most wiping off on the Windshield rain brush bar of rainwater so far.
A kind of rain brush group is arranged at present, and two of assemblings or how parallel rain brush bar are wiped away clean effect with enhancing above, disclose as following patent:
The U.S. the 5th, 168, No. 595 patents " Windshield scraping article and rain brush group " disclose a kind of rain brush group, are articulated in a Wiper arm with single Wiper strip carrier, and the first rain brush bar and the second rain brush bar are housed on Wiper strip carrier.
The U.S. the 4th, 745, No. 653 patents " scraping article that has wiping/strike off/clean concurrently of conveying arrangement glass " disclose a kind of scraping article of multiple-cutting-edge, and the scraping article with two kinds of different profile constructions contacts with the cleaning face, and one of them has jagged section shape.
The U.S. the 4th, 567, No. 621 patents " combined type Windshield rain brush group " disclose a kind of rain brush group and are provided with a pair of branch rain brush scraping article element at a certain distance, are equipped with thin on it respectively and the rubber-like scraping blade.One scrapes packaged being located between the two rain brush scraping article elements, outside the thin and rubber-like in its corner outstanding two is scraped.
The U.S. the 4th, 339, No. 839 patents " Windshield rain brush " disclose a kind of rain brush and have the spaced scraping blade of pair of parallel, and a brushing tool is contained in the groove between two scraping blades.
The U.S. the 3rd, 916, No. 473 patents " rain brush that Windshield is used " disclose a kind of rain brush bar that contains the strip of long ditch, on rain brush bar base portion perforate are arranged, the liquid that can provide rain brush essence and so on via the passage that passes base portion flows to windscreen surface to long ditch along whole piece rain brush bar.
The rain brush of two scraping blades can provide more efficient and wipe away clean effect, because when wiping away, can tentatively scrape earlier examination by the first road scraping blade the preceding, then with after the second road scraping blade scrape with equidirectional finishing.
Above skill of lifting relevant two scraping blade rain brush, it makes with assembly cost higher and difficult, and in these related art techniques documents not mentioned how stock production with the production of the rain brush that reduces two scraping blades and the method for assembly cost.
Summary of the invention
The objective of the invention is to be to provide a kind of pair of scraping blade rain brush bar and method for making thereof, to overcome the defective of prior art.
