The three-scraping-piece flexible wall supported wiper connecting rod blade hydraulic type windscreen wiper that a wiper driving mechanism of the windscreen wiper performs hydraulic drive through a flexible pipe, is large in transfer torque, small in size and quick in response, is small in structural limitation during installation due to the fact that the hydraulic drive by means of the flexible pipe is adopted, is completely of a closed structure, is low in noise during working, is especially suitable for a complicated external environment structure and remote transmission and is not influenced by the outside, the defect that the wiper motor is burned down due to an external obstacle is avoided, interior noise is effectively reduced, the interior comfort of a vehicle in running is improved, a wiper rubber strip is supported by a flexible wall and can be well fit with a windscreen, and the efficiency of a three-scraping-piece structure is triple of the scraping efficiency of a common single scraping piece.
Description
Art
The present invention relates to a kind of rain brush driver train, belong to vehicle wiper field, the especially hydraulicdriven wiper of flexible duct.
Background technology
At present, the rain brush driver train majority of the wiper on market catches up with transmission for connecting, and noise during its work is comparatively large, and, connect and catch up with transmission device to be open type, comparatively large by external action, operationally easily cause rain shaving electrical machine to burn as run into barrier obstruction; The supporting station of the scraping blade of the adhesive tape for wiper blade on market is all rigidity usually, because windshield is curve form, in addition manufacture the reason such as reason and use procedure wearing and tearing and cause windshield surface imperfection defect, scraping blade under non-yielding prop is difficult to adapt to the change on windshield surface, and only has a scraping blade, and in the process struck off, scrape cleanliness low, strike off efficiency difference, not easily quick scraping, easily causes blurred vision, brings potential safety hazard to driving.
Summary of the invention
Comparatively large in order to overcome noise when existing wiper driver train works, and, connect and catch up with transmission device to be open type, comparatively large by external action, operationally as run into the drawback that barrier obstruction easily causes rain shaving electrical machine to burn; The scraping blade of scraping blade under non-yielding prop of adhesive tape for wiper blade is difficult to the change adapting to windshield surface, water efficiency is scraped low in the process struck off, not easily quick scraping, the invention provides a kind of three scraping blade flexible wall supporting rain brush connecting rod vane formula wipers, it is a kind of complete fully enclosed structure, noise is low, and not by external environment influence; Adhesive tape for wiper blade can be fitted with windshield better, and can scraping rapidly.
The technical solution adopted for the present invention to solve the technical problems is: a kind of three scraping blade flexible wall supporting rain brush connecting rod vane formula wipers, comprise rain shaving electrical machine (36) and rain brush driver train (70) and rain brush (31), it is characterized in that: rain brush axle drive shaft (50) is divided into passive rain brush axle drive shaft (32) and active rain brush axle drive shaft (49), and coaxially connects with the passive oil cylinder axle (51) of passive blade oscillating oil cylinder (34) and the actuating cylinder axle (52) of active blade oscillating oil cylinder (47) respectively; Passive oil cylinder axle (51) and actuating cylinder axle (52) are respectively equipped with passive oil cylinder dividing plate (33) and actuating cylinder dividing plate (37), between passive blade oscillating oil cylinder (34) and active blade oscillating oil cylinder (47), pass through hydraulic oil pipe (48) UNICOM and transmitting torque; Active blade oscillating oil cylinder (47) is provided with a connecting rod driving mechanism for rocker arm (53), its structure is: the initiatively rocking arm (61) being provided with coaxial linkage in actuating cylinder axle (52) axial side, initiatively rocking arm (61) is connected with the motor rocking arm (60) of motor gear (63) coaxial linkage by connecting rod (62), motor gear (63) is meshed with worm screw (46), one end of worm screw (46) connects with rain shaving electrical machine axle (45), and connecting rod driving mechanism for rocker arm (53) is located in closed structure.Hydraulic oil pipe (48) is flexible tube.
Described rain brush (31), adhesive tape for wiper blade fixed card slot (2) is provided with on the top of adhesive tape for wiper blade (1), bottom is provided with scraping blade (6), the both sides of the base plate (3) in adhesive tape for wiper blade fixed card slot (2) form left flexible wall (4) and right flexible wall (5) respectively to downward-extension, and this left and right flexible wall and the both sides of flexible wall base plate (13) being located at scraping blade (6) upper end cross the flexible wall supporting structure (7) of formation one hollow; Be respectively equipped with in the both sides of flexible wall base plate (13) bottom and middle part and prolong the left scraping blade (10) and right scraping blade (11) and middle scraping blade (14) that flexible wall supporting structure (7) axially be arranged in parallel.Scraping blade can adapt to the curved surface change of windshield better under the supporting of flexible wall supporting structure, and laminating makes to scrape cleanliness better increases, and three scraper structures are three times that general single scraping blade strikes off efficiency.
The wall thickness of left flexible wall (4) and right flexible wall (5) is by thick gradual change shape thinning gradually from the upper and lower side of wall to centre.The middle part outwardly convex of left flexible wall (4) and right flexible wall (5); Have weighting material (18) in described flexible wall supporting structure (7), weighting material is foamed rubber.This design has again good stability and non-deformability while making flexible wall supporting structure have good flexibility.
The upper end of left scraping blade (10) and right scraping blade (11) and middle scraping blade (14) is respectively equipped 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 prevents scraping blade from lodging, and rises and support and booster action, strengthens the toughness of scraping blade and have the effect preventing flexible wall supporting structure excessive deformation concurrently.
The invention has the beneficial effects as follows the rain brush driver train flexible duct hydrostatic drive of wiper, transmitting torque is large, volume is little, response rapidly, due to flexible duct hydrostatic drive, little by structural limitations during installation, and be enclosed construction completely, during work, noise is low, is especially applicable to external environment condition complex structure and long-distance transmission, can adapts to different automobile types, and not by external action, avoid the drawback because outer barrie thing causes rain shaving electrical machine to burn, significantly reduce internal car noise, improve the traveling comfort of inside during vehicle operating; Scraping blade rains better with the application of a surface degree of windshield in the supporting of flexible supporting structure, three scraper structures are three times that general single scraping blade strikes off efficiency, thus improve rain shaving blade scrape cleanliness, Clear & Transparent gaze area can be provided to driver rapidly, provide sound assurance to safe driving.
