The specific embodiment
Referring to figs. 1 through Fig. 3 as can be known, disturbed flow type windscreen wiper sheet assembly of the present invention comprises scraping blade adhesive tape 3, support 4, and scraping blade overcoat 2 (plug 1 is equipped with at its two ends) is housed on the described support 4, in this scraping blade overcoat 2 reed 7 is housed, and reed 7 links by clip 9 and scraping blade adhesive tape 3; Described scraping blade overcoat 2 (plays sunshade, aging-resistant protective effect to the scraping blade adhesive tape with reed 7, clip 9 and scraping blade adhesive tape 3 parcels for one; also replace former spoiler to make air-flow produce downforce to the scraping blade adhesive tape), scraping blade adhesive tape 3 (part) then is exposed to the outside of scraping blade overcoat 2.
Wherein, reed 7 is built in the scraping blade overcoat 2 (for plasthetics) as the spring steel shell fragment, as its real skeleton, makes it have flexural resilience, just because of its crooked soft, that elasticity well reaches pressure is even, and scraping blade adhesive tape and glass curve are fitted well; Be provided with flat filament 8 in the described scraping blade adhesive tape 3, to support the scraping blade adhesive tape better; The clip hook 12 of described clip 9 by its two ends be scraping blade adhesive tape 3 and solid being in the same place of flat filament 8 hoops, and the clip hangnail locking plate 14 of clip 9 by its both sides is stuck in the reed trough of reed 7 clip and reed and flat filament are linked together (as shown in Figure 3, Figure 4); As shown in Figure 1 and Figure 2, jump ring 6 is equipped with by jump ring pin 5 in described support 4 tops, is used to connect the floating rule of wiper.
Disturbed flow type windscreen wiper sheet assembly is exactly the metallic framework that has replaced conventional wiper blades adhesive tape (being the windscreen wiper sheet) rear portion with single-piece scraping blade overcoat, reed and a clip, flat filament etc. in fact.The exoskeletal rain brush that is called for short not is genuine " no bone ", but an adaptive reed (spring steel shell fragment) is built in the scraping blade overcoat, flat filament (two stainless elastic steel sheet) is built in the scraping blade adhesive tape, to form flexible and the moderate elastic body of rigidity, reed and flat filament (spring steel shell fragment and two stainless elastic steel sheets) respectively just like the spine and the rib of human body, replace and are better than the combination metallic framework in the conventional confguration.Scraping blade adhesive tape, reed and flat filament closely combine flexible and the moderate elastic body of rigidity, its combination relies on several clips to finish, two clip hooks of clip hook scraping blade adhesive tape and flat filament, scraping blade adhesive tape, reed and flat filament are closely combined, after two clip hangnail locking plates of clip pass the reed trough of reed, because of elasticity struts, clip hangnail locking plate is stuck in the reed trough of reed, clip promptly is lockable and can not extracts, and closely combines reliably to guarantee scraping blade overcoat, reed, clip, scraping blade adhesive tape and flat filament.
The intelligent adaptive spring steel shell fragment system that this cover is unique makes that the windscreen wiper sheet can rectangular distribution pressure, makes windscreen wiper sheet each several part stress balance, has improved the drawback of traditional rain brush to a great extent.Scraping blade adhesive tape (rain brush rubber) is the special brontosaurus technical finesse of process, the scraping blade overcoat of scraping blade adhesive tape and flat filament outsourcing has the effect of sunshade anti-aging, scraping blade adhesive tape (windscreen wiper sheet) adopts exoskeletal unsteady steel disc structure, the scraping blade adhesive tape is very pliable and tough, be not easy residual when wiper ice and snow, grit, can thoroughly eliminate original motion phenomenon of shaking, and the life-span long, in light weight (thereby prolong Wiper motor, connecting rod life-span), stronger than traditional rain brush adhesive ability, brush totallyer.
The common speed per hour of Modern Car has reached about 100 kilometers, F-Zero more reaches more than 200 kilometers, therefore the vehicle body of car and expose attachment design and should obey aerodynamics, the sky resistance coefficient of trying one's best low is arranged, take measures again, at the front and back end of vehicle body mounting guiding board and spoiler, to guarantee the driving safety of car.With the supporting Windshield Wiper that is installed in the front windshield glass outside face of vehicle body, because the effect of its high velocity air that heads on, have and make the windscreen wiper sheet raise the trend that breaks away from the front windshield glass surface, therefore, though originally floating rule is because the effect of spring produces thrust to the windscreen wiper sheet, but the windscreen wiper sheet can reduce generally to the pressure that front windshield glass produces, and can directly influence the wiper quality thus and makes and scrape cleanliness and reduce.For this reason, traditional solution is to increase by a cover spoiler device on the windscreen wiper sheet, and utilizing head-on, high velocity air produces pressure to spoiler, offset high velocity air produces thrust to the windscreen wiper sheet minimizing, its shortcoming is: cost increases, and windscreen wiper sheet weight increases, and windscreen wiper sheet force-bearing situation is degenerated.Therefore, the present invention makes the scraping blade overcoat outside face curved surface of disturbed flow type windscreen wiper sheet assembly the arc surface of parabola face or approximate parabola face.As Fig. 3, shown in Figure 5, the curved surface of described scraping blade overcoat 2 outside faces is parabola face or arc surface, is scraping blade overcoat flow-disturbing surface curve 11, has the flow-disturbing effect, to obtain aerodynamics effect preferably.
As shown in Figure 5, establish the P that makes a concerted effort to be of the airflow acting force that acts on the scraping blade overcoat flow-disturbing face, the point of action that the P that makes a concerted effort acts on the scraping blade overcoat flow-disturbing face is 01, and the point of action that the P that makes a concerted effort acts on the windshield plane 10 is O
2, the point of action of the application force P through being converted to scraping blade adhesive tape cutting edge is O
3, point of action O
2And O
3Between distance be L.The P that makes a concerted effort that then produces airflow acting force is converted to the application force P and the moment M:M=PLSin β of scraping blade adhesive tape cutting edge; The normal component of P on scraping blade overcoat flow-disturbing face is Pn with joint efforts, as calculated: Pn=PSin β; The component of P on windshield plane 10 is Pt with joint efforts, as calculated: Pt=PCos β (wherein the angle between windshield plane 10 and the horizontal surface 13 is β).Act on the airflow acting force P on scraping blade overcoat flow-disturbing face, the point of action that is converted to scraping blade adhesive tape cutting edge is O
3, this has just produced application force Pn, Pt and moment M, is respectively as calculated:
1. Pn=PSin β, this power has produced pressure for the effect owing to air-flow to the scraping blade adhesive tape, offset and the supporting Windshield Wiper that is installed in the front windshield glass outside face of vehicle body, because the head-on effect of high velocity air, its windscreen wiper sheet is raised broken away from the front windshield glass surface, originally floating rule is because the pressure minimizing that the effect of spring produces thrust and front windshield glass is produced the windscreen wiper sheet.
2. Pt=PCos β, this power is for because the effect of air-flow has produced upwards thrust to the scraping blade adhesive tape.Because Windshield Wiper is in a circulation of work, the load of half working cycle that makes progress is bigger than half downward working cycle, and upwards thrust has just in time played equilibrium activity.
3. M=PLSin β, this power is because the overturning couple that the effect of air-flow produces scraping blade adhesive tape cutting edge.Because the wiper of scraping blade adhesive tape requires, the corresponding upset of scraping blade adhesive tape cutting edge, be that the scraping blade adhesive tape is not when working, scraping blade adhesive tape cutting edge is vertical with driving surface glass, when wiper, the upset of scraping blade adhesive tape cutting edge, the angle of scraping blade adhesive tape cutting edge and sense of motion (angle of contact) must acutangulate (＜90 °), and this moment will help the corresponding upset of scraping blade adhesive tape cutting edge when half working cycle that makes progress, and help improving the wiper quality.
The present invention can be applicable to various Windshield Wipers supporting on the vehicle.
