The specific embodiment
Fig. 1 shows the cross-sectional plane of the wiper strip of the present invention's suggestion.This cross-sectional plane is divided into fixed part 1 and water wiping lip 3, and they are interconnected by centre portion 2.
According to the embodiment of Fig. 1, fixed part 1 has the roughly cross-sectional plane of T shape.Form groove 12 in the wiper strip both sides thus, can act on an anchor fitting on it, this anchor fitting is arranged on the end of scraping the water arm.Fixed part can be made by a kind of poly-mer for 1 this moment.Cross-sectional plane shown in Figure 1 can be constant on the whole longitudinal extension length of wiper strip.Can move like this and scrape the water arm and at random locate along the longitudinal extension length of wiper strip.But fixed part 1 only is provided with along the longitudinal extension length of wiper strip on preposition in another kind of form of implementation of the present invention, thereby has determined the clearly location of wiper strip on the arm of wiper device.Wiper strip be not that the remainder that is used for fixing then has the cross-sectional plane different with Fig. 1, for example fixed part 1 can fully phase out and cross-sectional plane has straight dorsal surface.
To scrape the water result and/or obtain abrasion protection in order to improve, can coat a kind of coating on side 18a and/or side 18b and/or the areal of support 19, it for example has hydrophobic property.According to particular case, this coating also can improve the hardness of the material in the water wiping lip zone and play additional abrasion protection thus.This coating can be used to improve the sliding properties of water wiping lip 3 on Windshield in addition.This coating for example can comprise a kind of plasma polymer that contains hydro-carbon.
The shaping form of water wiping lip 3 for example can improve extrusion process or extrusion molding to be realized.Alternatively, side 18 or areal of support 19 also can carry out the back processed by cutting or non-cutting, for example by grinding or cutting.
In order to realize the above-mentioned flip-flop movement of water wiping lip 3, be provided with an elastomeric centre portion 2.In this centre portion 2, be furnished with spring rail bar 10.This spring rail bar can be for example with the plastics or the spring steel band manufacturing of hardness greatly.Spring rail bar 10 task at this moment is to distribute on the longitudinal extension length of wiper strip by the pressure that is directed on the wiper strip with scraping water arm point-like.Thus water wiping lip 3 with each contact point of Windshield on whole length, be subjected to constant the pushing of power.
Realized water wiping lip movement in the horizontal by a cavity 4, this cavity has the cross-sectional plane of general triangular in the embodiment according to Fig. 1.Cavity side face 4 this moment is limited by two sidewall 5a and 5b, and is limited by the contact surface with fixed part 1.
For water wiping lip 3 can freely be moved, centre portion 2 is by another kind of material manufacture.For example fixed part 1 and centre portion 2 can be made extruding in the processing jointly of two kinds of different plastic material with water wiping lip 3, thereby obtain having the fixed part 1 of big hardness and centre portion 2 and the water wiping lip 3 with less hardness in a manufacturing procedure.Especially can consider that thermoplastic elastomer or elastomeric material are as the material that is used for wiper strip.
The wall thickness of sidewall 5a and 5b is selected according to the modulus of elasticity of the material that uses this moment, makes the friction force that acts on the water wiping lip 3 by areal of support 19 be enough to water wiping lip 3 is overturn on against sense of motion.
For fear of upset and wiper strip et out of order too consumingly thus, in cavity 4, also be provided with stop part 6 with spring rail bar 10.This stop part 6 has a shape roughly complementary with cavity 4 at this moment.In the embodiment in figure 1, cavity 4 has the cross-sectional plane of general triangular.Correspondingly, stop part 5 also has the shape of general triangular.
The movement of the requirement of water wiping lip 3 for example can guarantee in this wise that promptly stop part 6 is constructed roughly more lessly than cavity 4.In a kind of preferred form of implementation, stop part 6 has recessed outside face 8a and 8b, the outside face 5a and the 5b mating reaction of the projection of itself and restricted arm.Water wiping lip 3 remaining movements are determined by the size of remaining cavity 4 except the modulus of elasticity of restricted arm 5a and 5b and thickness thus.
The stop part 6 of general triangular has stop surface 7, stop part by this stop surface apical grafting to spring rail bar 10 and be fixed on like this in the cavity 4 of centre portion 2.With respect to stop surface 7, stop part 6 has seamed edge 9.This seamed edge can be constructed for 9 this moments in this wise, makes it and water wiping lip 3 mesh and limit the run-on point of water wiping lip flip-flop movement.
Of the present invention a kind of expansion scheme in, stop part 6 and spring rail bar 10 also can be unified into a mono-member.This member is for example made in common extrusion molding by two kinds of different plastics.The stop part of being made by thermoplastic elastomer or rubber can contain metallo-spring rail bar 10 in addition, and the latter for example is embedded in press casting procedure in the stop part 6.
Fig. 2 shows another form of implementation of the present invention.Different with the diagram of wiper strip for carrying shown in Figure 1, Fig. 2 shows the cross-sectional plane of wiper strip under deformation state, and this is to form when the surface engaged of water wiping lip 3 and Windshield 11.
The similar of the structure of wiper strip shown in Figure 2 and the wiper strip of Fig. 1.But be noted that fixed part 1 and centre portion 2 are integrally to be made by commaterial.Between fixed part 1 and centre portion 2, form groove 12 equally, can insert in the groove and scrape the water arm.The shape that is noted that the cross-sectional plane of fixed part 1 only is to select for example.Also can consider other shape of cross section of fixed part 1 according to the difference of scraping the functional element on the water arm.Instruction of the present invention does not lie in the principle that is provided as solution with groove 12.As described in conjunction with Fig. 1, fixed part 1 can be provided with or only divide section ground to be provided with on the whole length of wiper strip.
Fig. 2 show when wiper strip when direction 16 has been loaded pressing force, this pressing force is for example applied by the water arm of scraping of automobile, according to the cross-sectional plane of the wiper strip of the present invention's suggestion.Wiper strip moves on Windshield 11 along direction 17 in addition.The surface engaged of following seamed edge 19 and Windshield 11.Have thus with sense of motion 17 oppositely directed friction force and act on the water wiping lip 3.This friction force causes the cross-sectional deformation of centre portion 2.Be applied a pressure on sense of motion lower wall 5b shown in Figure 2, this pressure causes sidewall bending and diminishes at a side upper plenum 4 that deviates from sense of motion.Sidewall 5b contacts with the restriction face 8b of stop part 6 thus.
On a relative side of this profile, a tension is on face 5a, thereby cavity 4 is held between the stop surface 8a of sidewall 5a and stop part 6.
Exempted from the excessive upset of water wiping lip 3 owing to act on trying hard to avoid on the sidewall 5b by stop part 6.Form roughly 35 ° between the side 18a of water wiping lip 3 and the surface of Windshield to 55 ° angle roughly.It is not bending curvature constant on all directions at Windshield on the path on the Windshield that this angular range is enough to compensate water wiping lip, thereby surperficial water wiping lip 3 is to lift and cause having not by the surface region of wiper from Windshield.
In case wiper strip reaches its position of turning back, pressure 16 maintenances exist, and sense of motion is reverse.This causes pulling force of effect in the sidewall 5b of cavity 4, and this pulling force causes sidewall 5b to lift from the restriction face 8b of stop part 6.Thereby pressure of effect on sidewall 5a, sidewall 5a leans on the stop surface 8a of stop part 6 thus.Cavity 4 diminishes in a side that deviates from sense of motion thus, thereby the profile of wiper strip becomes the shape with the diagram minute surface symmetry of Fig. 2 when sense of motion is reverse.
Fig. 3 shows the another kind of shape of cross section of wiper strip of the present invention.Fig. 3 shows a water wiping lip 3 and a centre portion 2 at this moment, as describing in conjunction with Fig. 2.But being illustrated on its whole length, Fig. 3 do not have constant cross-sectional plane.The wiper strip of opposite Fig. 3 has one first section, is connected on the centre portion 2 at this Duan Zhongyi fixed part 1, for example a kind of fixed part 1 as shown in Fig. 1 or 2.
Wiper strip has at least one second section in addition, has cross-sectional plane shown in Figure 3 in this section.This section is characterised in that has arranged that a bumper/spoiler 20 replaces fixed part 1.This bumper/spoiler 20 has wind-guiding face 14 and flow-disturbing seamed edge 15.Arrange wind-guiding limit 14 this moment in this wise, the feasible wind 18 that travels flows through from it and is diverted on the direction of flow-disturbing seamed edge 15 simultaneously.Produce additional pressure 19 by this air flows, lift from Windshield 11 even this pressure also prevents the water wiping lip 3 of wiper strip under higher speed.
Bumper/spoiler 20 also can equally with fixed part 1 be formed on the centre portion by means of a kind of common extrusion molding or die-casting technique.The modulus of elasticity of the material that uses according to centre portion 2, the professional adopts identical materials to be used for this bumper/spoiler 20 or adopts the material with different hardness, especially has the material of big hardness.
The wiper strip of being advised in a kind of preferred implementing form has in the middle of being disposed generally on first section, and this section comprises a fixed part 1 and second section of this both sides of first section, all is furnished with bumper/spoiler 20 for this second section.Wiper strip can also have two first section on its longitudinal extension part in another kind of form of implementation, and this first section has a fixed part 1 respectively, and three second section, be furnished with three bumper/spoilers 20 for this second section.The professional can be corresponding to selecting the longitudinal extension part branch is divided into first section and second section at the attachment point of scraping the wiper strip that is provided with on the water arm with corresponding to the pressure 19 of the hope that acts on by bumper/spoiler 20.
