Description
Technical field
The present invention relates to middle technical field of polymer materials, especially a kind of wiper soft-hard coextrusion flow-disturbing wing and preparation method thereof.
Background technology
The flow-disturbing wing is vapour Novel vehicle without one of core component of bone windscreen wiper, windscreen wiping system for automobile by motor, connecting rod, rocking arm and wiper blade four parts form, keep Windshield outside face to clean to guarantee that sleety weather gets a clear view and traffic safety, the indispensable parts of power actuated vehicle, wherein rain shaving blade again by the flow-disturbing wing, scrape glue bar, metallic support sheet, plastic tip and attaching parts and form.
Tradition rain brush has various structures, wherein a kind of steel bar structure windscreen wiper being typically generally 6 to 8 fulcrums, the elasticity of steel bar is relied on to make rain shaving blade be close to Windshield by 6 to 8 fulcrums, not only heavier-weight, complex structure, and unbalance stress, make the wiper life-span short, noise is large, as shown in Figure 1.Because its scraping blade back side is not designed with the flow-disturbing wing, make when automobile driving speed is higher, powerful windage will make rain shaving blade by air lifting, can not complete laminating windshield surface, make to scrape water effect greatly to decline, and shake easily occurs and sends larger noise.
Another typical traditional windscreen wiper is considered and is utilized air resistance and make scraping blade fit tightr on the windshield, devises and installed flow-disturbing plastic sheet additional on steel structure wiper bracket, as shown in Figure 2.This spoiler is that injection moulding is produced, length is short, area is comparatively large and heavier-weight, air draught lifting when the thrust utilizing air draught to produce during use makes rain shaving blade do not run at high speed, make scraping blade can compress windscreen surface all the time, but due to pressure distribution inequality, but effect is not very desirable, and structural adhesion is complicated, itself due to volume large, Heavy Weight, self windage is larger.
Summary of the invention
The object of the invention is: a kind of wiper soft-hard coextrusion flow-disturbing wing and preparation method thereof, it can be pressed on windscreen surface by whole piece windscreen wiper uniformly, air draught lifting when rain shaving blade is not run at high speed, can better by water scraped clean on glass, avoid shaking, and compact, to overcome the deficiencies in the prior art.
The present invention is achieved in that the wiper soft-hard coextrusion flow-disturbing wing, comprises assembling skeleton and flow-disturbing wing main body, the thermoplastic plastic of the material of assembling skeleton to be shore hardness be 95-100 degree; The thermoplastic elastic material of the material of flow-disturbing wing main body to be shore hardness be 60-62 degree; Assembling skeleton is trench structure, is provided with assembling draw-in groove in the inner side of assembling skeleton; The composition of flow-disturbing wing main body comprises the wind-engaging body of arcuate structure, supporter and connector, wind-engaging body, is interconnected and is integrated, and form a cavity between supporter and connector between its join domain; Connector is connected with assembling skeleton.
The supporter of flow-disturbing wing main body is that wind-engaging body provides support, and can keep specific shape and be not easy distortion.
The cavity effect that flow-disturbing wing main body is formed makes the limit wall thickness in flow-disturbing wing main body as far as possible even, when being convenient to extrude, plastic liquid distribution of pressure is even, is convenient to formed product, can alleviate product weight by actv. simultaneously, cost-saving, the flow-disturbing wing can also be made to keep better elasticity.
Assembling skeleton provides enough intensity and rigging position for the flow-disturbing wing is longitudinal, improve the melt strength extruding stock simultaneously, be convenient to product extrusion molding, also play and keep product size to stablize, be unlikely to easily tensile deformation to occur, guarantee the reliable effect used.
The wind surface of described wind-engaging body is made up of the arc surface of 4 sections of smooth connections, the radius ratio R1:R2:R3:R4 of 4 sections of arc surfaces is 1:25:18:26, the arc length of 4 sections of circular arcs is 1:12:4:2 than L1:L2:L3:L4, wherein second segment arc surface is the main wind surface of wind-engaging body, and the ratio of its arc length L2 and radius R 2 is 6:7.Smooth connection refers to that the junction tangent line of arc surface is overlapping.
The relation of the arc length L2 of the length L of bearing surface and the main wind surface of wind-engaging body is L:L2 is 3:3.8-4.2.
The overall width W1 of assembling skeleton, the relation of hard-edge width W 2 and thickness D is, W1:W2=5:1, W1:D=16:1.Guarantee that the flow-disturbing wing and windscreen wiper component connect reliably, while is convenient for assembly again.
The assembling draw-in groove arranged inside flow-disturbing wing main body is for assembling with metal spring sheet, and the width between assembling draw-in groove is slightly less than windscreen wiper sheetmetal width, makes flow-disturbing wing energy close fit on the sheetmetal of wiper, and is unlikely to slide or come off.
Shore hardness is the thermoplastic plastic of 95-100 degree and shore hardness by the wiper preparation method of the soft-hard coextrusion flow-disturbing wing is the mode one-shot forming of thermoplastic elastic material with composite co-extruding of 60-62 degree, obtains the profile shapes of said structure.
Owing to have employed technique scheme, compared with prior art, the present invention, according to aerodynamic principle, adopts the spoiler surface of special radian, makes automobile in the process of moving, on windscreen wiper, air resistance directly acts on flow-disturbing wing surface, make its uniform force, the thrust of generation directly acts on whole piece windscreen wiper swept area of wiper blade, makes it fit tightly windshield, windscreen wiper by water scraped clean on glass, can better not shaken; Make rain brush can normal function under circumstances, and reduction work noise, extend its service life, it is simple that the present invention disturbs structure, volume is little, can strengthen the driver and conductor visual field, and assembles easy for installation when changing, its slightly wide flow-disturbing face main body can also block ultraviolet, greatly extends effects such as scraping glue bar service life.。Structure of the present invention is simple, and easily produce, with low cost, result of use is good.
