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 hydraulic pressure
Swinging wiper, it is a kind of completely enclosed structure, and noise is low, and not by outside
Environmental effect；Adhesive tape for wiper blade can preferably be fitted with windshield, and can shave rapidly.
The technical solution adopted for the present invention to solve the technical problems is: a kind of three scraping blades are soft
Property wall supporting rain brush swing hydraulic pressure wiper, drive machine including rain shaving electrical machine 36 and rain brush
Structure 70 and rain brush 31, is characterized in that: rain brush drive shaft 50 is divided into passive rain brush to drive
Moving axis 32 and actively rain brush drive shaft 49, and respectively with driven gear tooth bar oscillating oil cylinder
The passive oil cylinder gear shaft 51 of 34 and the active oil of driving gear tooth bar oscillating oil cylinder 47
Cylinder gear shaft 52 coaxially connects；Driven gear tooth bar oscillating oil cylinder 34 and drive gear teeth
Pass through hydraulic oil pipe 48 UNICOM between bar oscillating oil cylinder 47 and transmit moment of torsion；At driving tooth
Wheel tooth bar oscillating oil cylinder 47 is provided with a positive gear intermittent drive mechanism 53, its knot
Structure is: be provided with the actuating cylinder of coaxial linkage in the axial side of actuating cylinder gear shaft 52
Driving gear 38, the radially opposite sides at actuating cylinder gear shaft 52 are symmetrical arranged two and half
Knucle-gear, i.e. right semi-circle gear 41 and left semicircle gear 42, drive with actuating cylinder respectively
Moving gear 38 alternately engagement；Axial at right semi-circle gear 41 and left semicircle gear 42
Side arrange two respectively with right semi-circle gear 41 and left semicircle gear 42 coaxial linkage

Right driving gear 39 can be driven to become adverse movement with left driving gear 40, meanwhile, coaxially
The right semi-circle gear 41 of linkage also becomes adverse movement with left semicircle gear 42, due to the right side half
It is alternately to engage that Knucle-gear 41 and left semicircle gear 42 drive gear 38 with actuating cylinder,
When right semi-circle gear 41 drives gear 38 to engage with actuating cylinder, actuating cylinder drives
Gear 38 moves in one direction, and when left semicircle gear 42 drives tooth with actuating cylinder
During wheel 38 engagement, actuating cylinder drives gear 38 to move in the opposite direction, thus drives
Rain brush moves back and forth.Hydraulic oil pipe 48 is flexible pipe.
Described rain brush 31, is provided with adhesive tape for wiper blade fixed card slot 2 on the top of adhesive tape for wiper blade 1,
Bottom is provided with scraping blade 6, along windscreen wiper in the base plate 3 of described adhesive tape for wiper blade fixed card slot 2
The most symmetrical two tubular cavities that be arranged in parallel of adhesive tape 1, left cavity 17 and the right side
Cavity 16, forms left flexible wall 4 and right flexible wall 5 and median septum 12, base plate 3
Flexible wall supporting structure 7 is constituted with left cavity 17 and right cavity 16；At base plate 3
The lower end at both sides and middle part is respectively equipped with and sets along flexible wall supporting structure 7 is axially in parallel
The left scraping blade 10 put and right scraping blade 11 and middle scraping blade 14.Scraping blade supports at flexible wall
Can better adapt to the curved surface change of windshield under structure support, preferably laminating makes
Scraping cleanliness to increase, two tubular cavities, while ensureing flexible wall flexibility, possess again one
Fixed anti-excessive deformation also keeps stable effect, and three scraper structures are general singly scraping
Sheet 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 thickness
The most thinning gradual change shape.Left flexible wall 4 and the middle part outwardly convex of right flexible wall 5.
This design makes flexible wall supporting structure have again while having good flexibility very well
Stability.
The upper end of left scraping blade 10 and right scraping blade 11 and middle scraping blade 14 is respectively equipped with a left side and scrapes
Sheet inverted trapezoidal supporting station 9 and right scraping blade inverted trapezoidal supporting station 8 and middle scraping blade inverted trapezoidal prop up
Cushion cap 15.The design of inverted trapezoidal supporting station is to prevent scraping blade from lodging, and rises to support and add and pretends
With, strengthen the toughness of scraping blade and have the work preventing flexible wall supporting structure excessive deformation concurrently
With.
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, two tubular cavities, while ensureing flexible wall flexibility, possess again certain anti-mistake
Spending the effect deforming and keeping stable, single scraping blade that three scraper structures are general strikes off efficiency
Three times, thus improve rain shaving blade scrape cleanliness, it is possible to provide clear to driver rapidly
Transparent gaze area, provides sound assurance to safe driving.
