Description

Three scraping blade flexible wall circular hole inner support rain brush cable type wipers
Affiliated technical field
The present invention relates to a kind of wiper, belong to vehicle wiper field, especially use driven by quill shaftWiper.
Background technology
At present, the rain brush driving mechanism majority of the wiper on market is link transmission, its workTime noise larger, and jointed gear unit is open type, is subject to external action larger,When work, stop and easily cause rain shaving electrical machine to burn as run into barrier; Adhesive tape for wiper blade on marketThe supporting station of scraping blade is all rigidity conventionally, because windshield is curve form, manufactures in additionThe reasons such as reason and use procedure wearing and tearing cause windshield surface imperfection defect, in rigidityScraping blade under supporting is difficult to adapt to the variation on windshield surface, and only has a scraping blade,In the process of striking off, scrape cleanliness low, strike off efficiency poor, be difficult for quick scraping, easily cause sight line mouldStick with paste, bring potential safety hazard to driving.
Summary of the invention
While work in order to overcome existing wiper driving mechanism, noise is larger, and connecting rod passesActuation mechanism is open type, is subject to external action larger, in the time of work, stops easily as run into barrierThe drawback that causes rain shaving electrical machine to burn; The scraping blade of the scraping blade of adhesive tape for wiper blade under non-yielding prop veryThe difficult variation that adapts to windshield surface is scraped water efficiency low in the process of striking off, and is difficult for fastSpeed scraping, the invention provides a kind of three scraping blade flexible wall circular hole inner support rain brush cable type windscreen wipersDevice, it is a kind of complete totally enclosed structure, noise is low, and is not subject to external environment influence;Adhesive tape for wiper blade can be better and windshield laminating, and scraping rapidly.
The technical solution adopted for the present invention to solve the technical problems is: a kind of three scraping blade flexibilitiesWall circular hole inner support rain brush cable type wiper, comprises rain shaving electrical machine 36 and rain brush driving mechanism70 and rain brush 31, it is characterized in that: rain brush driving shaft 50 is divided into passive rain brush driving shaft 32With active rain brush driving shaft 49, and the passive rain brush of being located at respectively passive tooth holder 34 drivesIn the active rain brush drive shaft hole 52 of moving axis hole 51 and driving tooth holder 47. Passive rain brushOn driving shaft 32 and active rain brush driving shaft 49, be respectively equipped with driven gear 33 and driving gear37, between driven gear 33 and driving gear 37, connect and transmitting torque by flexible axle 35.On driving gear 37, be provided with a positive gear intermittent drive mechanism 53, its structure is:Be provided with the driving tooth driven wheel 38 of coaxial linkage in the axial side of driving gear 37, leadingThe radially bilateral symmetry of moving rain brush driving shaft 49 arranges two semi-circle gears, i.e. right semi-circle gear41 and left semicircle gear 42, alternately engage with driving tooth driven wheel 38 respectively. On the right side partlyAn axial side of Knucle-gear 41 and left semicircle gear 42 arrange two respectively with right semi-circle gear41 and right driven wheel 39 and the left driven wheel 40 of left semicircle gear 42 coaxial linkages,Between right driven wheel 39 and left driven wheel 40, being provided with one drives with right driven wheel 39 and a left sideThe worm screw 46 that moving gear 40 is meshed, one end of worm screw 46 and rain shaving electrical machine axle 45 join.In the time that rotating, worm screw 46 can drive 40 one-tenth of right driven wheel 39 and left driven wheels oppositely to transportMoving, meanwhile, the right semi-circle gear 41 of coaxial linkage also becomes oppositely fortune with left semicircle gear 42Moving, because right semi-circle gear 41 and left semicircle gear 42 are to hand over driving tooth driven wheel 38For engagement, in the time that right semi-circle gear 41 engages with driving tooth driven wheel 38, driving tooth drivesMoving gear 38 moves towards a direction, and when left semicircle gear 42 and driving tooth driven wheelWhen 38 engagement, driving tooth driven wheel 38 moves in the opposite direction, thereby drives rain brush to doMove back and forth. Flexible axle 35 outsides are provided with flexible shaft protecting 48, shield, and flexible axle 35For flocking spiral flexible axle.
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, it is characterized in that: at the windscreen wiper glue of described adhesive tape for wiper blade fixed card slot 2Interior axial symmetrical two the tubulose skies that be arranged in parallel along adhesive tape for wiper blade 1 of clamp bar slot base plate 3Chamber, left cavity 17 and right cavity 16, form left flexible wall 4 and right flexible wall 5 and inNext door 12, adhesive tape for wiper blade draw-in groove base plate 3 and left cavity 17 and right cavity 16 form flexibleWall supporting structure 7; Be respectively equipped with in the lower end, both sides of adhesive tape for wiper blade draw-in groove base plate 3 along flexibleLeft scraping blade 10 and right scraping blade 11 and middle scraping blade 14 that wall supporting structure 7 axially parallels arrange.The curved surface that scraping blade can adapt to better windshield under the supporting of flexible wall supporting structure becomesChange, laminating makes to scrape cleanliness better increases, and two tubular cavities are ensureing flexible wall flexibilityMeanwhile, possess again certain anti-excessive deformation and keep stable effect, and three scraper structuresIt is three times that general single scraping blade strikes off efficiency.
The wall thickness of left flexible wall 4 and right flexible wall 5 from the upper and lower side of wall be to centre by thick byThe gradual change shape that gradual change is thin. The middle part outwardly convex of left flexible wall 4 and right flexible wall 5. ThisDesign has again well stable when making flexible wall supporting structure have good flexibilityProperty.
The upper end of left scraping blade 10 and right scraping blade 11 and middle scraping blade 14 is respectively equipped with left scraping bladeTrapezoidal supporting station 9 and right scraping blade inverted trapezoidal supporting station 8 and middle scraping blade inverted trapezoidal supporting station15. The design of inverted trapezoidal supporting station is to prevent scraping blade lodging, rises and supports and booster action, strengthensThe toughness of scraping blade also has the effect that prevents flexible wall supporting structure excessive deformation concurrently.
The invention has the beneficial effects as follows the rain brush driving mechanism soft axle transmission of wiper, andBe enclosed construction completely, when work, noise is low, be especially applicable to external environment condition complex structure withAnd long-distance transmission, can adapt to different automobile types, and not be subject to external action, avoided because of outsideThe drawback that portion's barrier causes rain shaving electrical machine to burn, has reduced internal car noise effectively, improvesThe comfortableness of inside when vehicle operating. Scraping blade rains and wind in the supporting of flexible supporting structureThe application of a surface degree of gear glass is better, thus improve rain shaving blade scrape cleanliness, two tubulose skiesChamber, in ensureing flexible wall flexibility, possesses again certain anti-excessive deformation and keeps stableEffect, three scraper structures are three times that general single scraping blade strikes off efficiency, strike off efficiency and carryHeight, can provide Clear & Transparent sight line region to driver rapidly, provides to safe drivingSound assurance.
