Description
Art
The present invention relates to a kind of rain brush drive mechanism, belong to vehicle wiper field, especially
The hydraulicdriven wiper of flexible duct.
Background technology
At present, the rain brush drive mechanism majority of the wiper on market is link transmission, its
Noise during work is relatively big, and, jointed gear unit is open type, by external action
Relatively big, the most such as run into barrier obstruction and be easily caused rain shaving electrical machine and burn；On market
The supporting station of scraping blade of adhesive tape for wiper blade be the most all rigidity, owing to windshield is bent
Face shape, manufactures the reason such as reason and use process abrasion in addition and causes windshield table
Face random defect, the scraping blade under non-yielding prop is difficult to adapt to the change on windshield surface
Changing, and only one of which scraping blade, it is low to scrape cleanliness during striking off, and strikes off inefficient,
It is difficult to quickly shave, easily causes blurred vision, bring potential safety hazard to driving.
Summary of the invention
During in order to overcome existing wiper drive mechanism to work, noise is relatively big, and, connecting rod
Drive mechanism is open type, relatively big by external action, the most such as runs into barrier resistance
Gear is easily caused the drawback that rain shaving electrical machine burns；The scraping blade of adhesive tape for wiper blade is under non-yielding prop
Scraping blade is difficult to adapt to the change on windshield surface, scrapes water efficiency during striking off
Low, it is difficult to quickly shave, the present invention provides a kind of three scraping blade flexible wall supporting rain brush connecting rods
Vane formula wiper, it is a kind of completely enclosed structure, and noise is low, and not
By external environment influence；Adhesive tape for wiper blade can preferably be fitted with windshield, and can be fast
Speed shaves.
The technical solution adopted for the present invention to solve the technical problems is: a kind of three scraping blades are soft
Property wall circular hole inner support rain brush connecting rod vane formula wiper, including rain shaving electrical machine (36)
With rain brush drive mechanism (70) and rain brush (31), it is characterized in that: rain brush drive shaft
(50) passive rain brush drive shaft (32) and active rain brush drive shaft (49) it are divided into, and
Respectively with passive oil cylinder shaft (51) and the active blade of passive blade oscillating oil cylinder (34)
The actuating cylinder axle (52) of oscillating oil cylinder (47) coaxially connects；Passive oil cylinder shaft (51)
Be respectively equipped with passive oil cylinder dividing plate (33) and actuating cylinder on actuating cylinder axle (52)
Dividing plate (37), passive blade oscillating oil cylinder (34) and active blade oscillating oil cylinder (47)
Between by hydraulic oil pipe (48) UNICOM transmit moment of torsion；Active blade oscillating oil cylinder (47)
Being provided with a connecting rod driving mechanism for rocker arm (53), its structure is: in actuating cylinder axle (52)
Axially side is provided with the initiatively rocking arm (61) of coaxial linkage, and initiatively rocking arm (61) passes through

Described rain brush (31), is provided with adhesive tape for wiper blade on the top of adhesive tape for wiper blade (1) and fixes
Draw-in groove (2), bottom is provided with scraping blade (6), it is characterized in that: fix at described adhesive tape for wiper blade
Axial symmetrical parallel along adhesive tape for wiper blade (1) in the base plate (3) of draw-in groove (2)
Two tubular cavities, left cavity (17) and right cavity (16) are set, form left flexibility
Wall (4) and right flexible wall (5) and median septum (12), base plate (3) and left cavity
(17) and right cavity (16) constitute flexible wall supporting structure (7)；In base plate (3)
Lower end, both sides be respectively equipped with and prolong the left side that flexible wall supporting structure (7) is arranged in an axially parallel mode
Scraping blade (10) and right scraping blade (11) and middle scraping blade (14).Scraping blade props up at flexible wall
The lower curved surface change that can better adapt to windshield of bearing structure supporting, preferably fits
Making to scrape cleanliness to increase, two tubular cavities, while ensureing flexible wall flexibility, possess again
Certain anti-excessive deformation also keeps stable effect, and three scraper structures are general lists
Scraping blade strikes off three times of efficiency.
The wall thickness of left flexible wall (4) and right flexible wall (5) from the upper and lower side of wall to centre
In by the most thinning gradual change shape of thickness.In left flexible wall (4) and right flexible wall (5)
Portion's outwardly convex.While this design makes flexible wall supporting structure have good flexibility
There is again good stability.
The upper end of left scraping blade (10) and right scraping blade (11) and middle scraping blade (14) is respectively
Be provided with left scraping blade inverted trapezoidal supporting station (9) and right scraping blade inverted trapezoidal supporting station (8) and
Middle scraping blade inverted trapezoidal supporting station (15).The design of inverted trapezoidal supporting station is to prevent scraping blade from lodging,
Rise and support and booster action, strengthen the toughness of scraping blade and have concurrently and prevent flexible wall supporting structure
The effect of excessive deformation.
The invention has the beneficial effects as follows the rain brush drive mechanism flexible duct liquid of wiper
Pressure transmission, transmission moment of torsion is big, and volume is little, and response is rapid, owing to flexible duct hydraulic pressure passes
Dynamic, architectural limitation little during installation, and be enclosed construction, noise during work completely
Low, it is especially suitable for external environment condition structure complexity and long-distance transmission, it is possible to adapt to difference
Vehicle, and being independent of outside influences, it is to avoid because outer barrie thing causes rain shaving electrical machine to burn
Drawback, significantly reduce internal car noise, improve vehicle run time within comfortable
Property；Scraping blade rains the application of a surface degree with windshield more in the supporting of flexible supporting structure
Good, thus improve the cleanliness of scraping of rain shaving blade, two tubular cavities are ensureing flexible wall flexibility
While, possess again certain anti-excessive deformation and keep stable effect, three scraping blades knots
Single scraping blade that structure is general strikes off three times of efficiency, strikes off efficiency and improves, it is possible to gives rapidly
Driver provides Clear & Transparent gaze area, provides strong guarantor to safe driving
Barrier.
