Abstract
The invention provides a jet wiper arm assembly, which comprises wiper arm lining seats, a wiper bodies, a fan, an air flow inlet and an air flow outlet, wherein the wiper arm lining seats are fixed on output shafts of wiper motor connecting rods; both of the wiper bodies have two deflecting and reversing arc faces between which an air flow channel is formed; the fan is used for supplying wind; and the air flow inlet is wider than the air flow outlet which is a narrow and long outlet. The wiper bodies are made of transparent glass fiber reinforced plastics. The jet wiper arm assembly can remove water traces on a front windscreen in a jet mode, which has the advantages of reducing unnecessary wear friction loss, removing sand, dust and the like and achieving better wiping effect compared with the conventional wiper direct contact mode. The transparent wiper arms are made of the glass fiber reinforced plastics, so a contrast ratio is lowered and the interference of the wiper arms with the sight of drivers is relieved.
Description
Technical field
The present invention relates to automotive field, especially a kind of jet wiper arm assembly.
Background technology
At present, the windscreen wiper sheet is divided into two kinds of skeleton type windscreen wiper and no bone windscreen wipers (also being flat scraping blade), the transmission of pressure of the two all is to be delivered on the interface arrangment of scraping blade by point on the floating rule, and then by skeleton structure or stage clip (steel disc, or title elasticity sliver) power is delivered on the adhesive tape.The two all is to remove water mark on glass by the direct contact of adhesive tape and glass, and adhesive tape is under the motion of long-term pressurized, and very easily wearing and tearing belong to consumable accessory, and is easy to generate shake, abnormal sound, scrapes phenomenons such as unclean.In addition, traditional windscreen wiper sheet can cause nonvolatil damage to the adhesive tape cutting edge of scraping blade when being used for removing the grains of sand on the front windshield glass, and scraping cleanliness will be badly damaged.And, need expend many electric power because overcome the acting of contact friction resistance.
Also have, for people's vision system, the object in the picture, especially body in motion, contrast ratio is big more, can cause the attention of sight line more, and disturbing can be big more.Just attention can be disperseed, and can not concentrate on the road conditions in the place ahead.The scraping arm scraping blade of traditional black monotone can cause interference to driver vision when windscreen wiper arm and scraping blade motion.
Summary of the invention
The object of the present invention is to provide a kind of windscreen wiper sheet of removing the washmarking of front windshield glass with jet mode.
Air flow inlet concerns than below existing with the air flow outlet gas pressure intensity: P1/P2=S2/S1, be the P1*S1=P2*S2 (pressure that P1 is an air-flow when the scraping arm inlet enters, S1 is the cross-sectional area of air flow inlet, and P2 is the pressure of air flow outlet, and S2 is the cross-sectional area of air stream outlet).Be the gas of identical flow velocity and pressure, by the different bore of cross-sectional area, its pressure and cross-sectional area are inversely proportional to.That is to say that if the cross-sectional area of air flow inlet is bigger, and the finedraw cross-sectional area of air stream outlet is very little, just can produce very big pressure at air flow outlet.So under the certain situation of the power of blowing engine, enlarge the cross-sectional plane product moment of air flow inlet and air stream outlet, the washmarking in the time of can producing very big pressure front windshield glass is rained is removed clean.
For achieving the above object, a kind of jet wiper arm assembly provided by the invention comprises: the scraping arm liner clamp is used for fixing on rain shaving electrical machine connecting rod output shaft; The scraping blade body has two cambered surfaces that play water conservancy diversion commutation effect, forms gas channel between two cambered surfaces; Blowing engine is used to provide wind-force; And air flow inlet and air stream outlet, air flow inlet wider width wherein, the narrower in width of air stream outlet is the elongated shape outlet.
Wherein, the width of air flow inlet is 30mm-50mm; The width of air stream outlet is 2mm-5mm.
Further, blowing engine is communicated with air flow inlet by rubber tubing, and air-flow carries out airflow-reversing through the gas channel that forms between two cambered surfaces.
Further, the scraping blade body is made by transparent glass fiber reinforced plastics.
The motor connection lever mechanism of wiper is with traditional the same among the present invention.
The present invention adopts the jet-driven mode to remove the washmarking of front windshield glass, has reduced unnecessary frictional loss than traditional scraping blade direct contact type, and can remove the grains of sand, dust etc., and wiper is effective.The transparent scraping arm that uses glass-felt plastic to make owing to reduced contrast ratio, has reduced the interference of scraping arm to pilot's line of vision.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is specifically described.
As shown in Figure 1, 2, jet wiper arm assembly comprises: scraping arm liner clamp 1 is used for fixing on rain shaving electrical machine connecting rod output shaft; Scraping blade body 7 has two cambered surfaces 4,5 that play guide functions, plays the effect that changes air flow line.Form gas channel between two water conservancy diversion cambered surfaces 4,5; Blowing engine 6, the storage battery acquisition electric energy from automobile front chamber is used to provide wind-force; Air flow inlet 2 and air stream outlet 3.
When blowing engine 6 energising running, air communication is crossed rubber tubing and is entered from the air flow inlet 2 of wider width, commutates through the gas channel that forms between two cambered surfaces 4,5, goes out from very narrow air stream outlet 3.The rain shaving electrical machine connecting rod mechanism is also started working in the time of blowing engine 6 motions, and the rotation of output shaft drives the jet-propelled arm assembly of scraping and moves reciprocatingly, and the high speed and high pressure gas of jet-propelled scraping arm ejection can be removed the washmarking of glass surface.For guaranteeing the speed and the amount of air inlet, it is enough that the width of air flow inlet 2 is wanted, and it is enough that the width of rubber tubing is also wanted; Usually this nozzle diameter is relatively good in 30mm-50mm left and right sides effect.In order to guarantee enough pressure removing washmarkings, air extractor duct must be narrow, usually the optional 2mm-5mm of this width.A large amount of gas is gone out from narrow slit, can produce very big pressure.
In sum, core of the present invention is to allow a large amount of gas go out from narrow slit, produces the washmarking that enough pressure is removed front windshield.And scraping arm employing transparent glass fiber reinforced plastics, can reduce the interference of chaufeur vision.
The present invention can not only remove the rainwater when raining, but also can remove the dust and the grains of sand that adhere on the front windshield glass.
