The specific embodiment
Fig. 1 shows a wiper system 10.This device comprises a support tube 12, and it respectively has a Wiper bearing 14 at the two ends of its longitudinal length.Be fixed with a motor bearing 16 at support tube 12 in addition, the above is equipped with a Windshield Wiper motor 18.This Windshield Wiper motor 16 drives wiper shafts 22 by push rod 20, and these wiper shafts 22 are bearing in 24 li of the supporting sections of Wiper bearing 14.
Fig. 2 shows an embodiment according to Wiper bearing 14 of the present utility model.As shown in Figure 2, Wiper bearing 14 comprises fixed parts 26, decoupling zero parts 30, bearing frame 32 and supporting section 24.Wherein, supporting section 24 has central through hole 34, and this through hole 34 is used for supporting wiper shaft 22; Bearing frame 32 comprises fixed sleeving 36, and it is substantially perpendicular to the Axis Extension of supporting section 24, and inserts and be fixed in the support tube 12.Bearing frame 32 forms extension 38 to the part that fixed parts 26 extends, and this extension 38 forms endless member 40 around fixed parts 26.Wherein fixed sleeving 36, extension 38 and endless member 40 all are the parts of bearing frame 32.
As shown in Figure 2, decoupling zero parts 30 have the crooked muscle 28 that extends shape by many and consist of, and these muscle 28 are connected from fixed parts 26 lateral extensions and with the endless member 40 of bearing frame 32.Simultaneously, these muscle 28 roughly are outward extending along its corresponding radial direction (for clear not shown) respectively, and namely these radial direction are consistent with corresponding muscle 28 bearing of trend roughly.As shown in Figure 2, these radial direction are coplanar, and each radial direction is determined same plane (P).Yet in other embodiments, these are coplanar radially also can determine a plurality of planes of being parallel to each other.
For architectural feature and the design considerations that is illustrated more clearly in decoupling zero parts 30, the particularly shape of muscle 28 and architectural feature, Fig. 3 and Fig. 4 further show the embodiment of decoupling zero parts among Fig. 2.By reading Fig. 3 and Fig. 4 and corresponding explanation thereof, will be appreciated that many muscle 28 of decoupling zero parts 30 are crooked extension the on any one direction in two direction in spaces randomly, perhaps crooked extension the on described two direction in spaces simultaneously.
Fig. 3 is the birds-eye view of Wiper bearing 14 shown in Figure 2, namely towards perpendicular to the view of seeing in conjunction with the direction of plane that Fig. 2 describes (P).As shown in Figure 3, many muscle 28 of decoupling zero parts 30 prolong respectively corresponding radial direction undulate and extend out to endless member 40 from fixed parts 26.
For many muscle 28 that decoupling zero parts 30 are described extend along the bending of space other direction, Fig. 4 schematically shows an independent muscle 28 is extended in the bending of space both direction.It will be appreciated that shown in Figure 4 is not the physical form of muscle 28 reality.As shown in FIG., defined space coordinates that are made of x, y and z axes, its midplane xOy is parallel with the described plane of Fig. 2 (P), the y axle with shown in radial direction corresponding to muscle 28 parallel.Also defined both direction D1 and D2, wherein D1 is perpendicular to plane xOy, and namely perpendicular to plane (P), the radial direction that D2 is parallel with plane (P) and corresponding with muscle 28 is vertical.
Defined direction D1 and D2 help to understand an independent muscle 28 and extend in the bending of space both direction.On the one hand, as shown in the figure, be understood that easily that because D1 is perpendicular to plane (P), the cross sectional shape S1 of the muscle of seeing towards the D1 direction is corresponding with the waveform shown in Fig. 3.The cross sectional shape S2 of the muscle of seeing towards the D2 direction on the other hand, also undulate stretches out.
By above-mentioned explanation one of ordinary skill in the art will appreciate that the true form of each bar muscle 28 of decoupling zero parts 30 among Fig. 2 be for two cross sections be that corrugated its cross sectional shape of cylinder V1(is S1) and its cross sectional shape of V2(be S2) at the common factor in space.
Its cross sectional shape of the muscle that provides in above-described embodiment is the quadrangle with fillet, and the cross sectional shape of muscle can be that circle, prismatic, polygon and other are irregularly shaped in other embodiments.
Should be noted and be understandable that, although many muscle 28 of the decoupling zero parts 30 shown in Fig. 2 embodiment all are that undulate extends, only see toward the direction that the undulate extension also is fine on D1 and D2 both direction.For example, every muscle in these many muscle 28 only sees that towards D1 direction (namely vertical with plane (P) direction) undulate stretches out, perhaps, every muscle in these many muscle 28 only sees that towards D2 direction (i.e. the direction vertical with plane (P) parallel and corresponding with this muscle radial direction) undulate stretches out.
Based on above-mentioned understanding, those of ordinary skills can easily utilize cad tools, and CATIA for example designs the structure of decoupling zero parts 30 shown in Figure 2.Constructing respectively the cross section by the wave-like of setting first is two cylinder V1 and the V2 that has vertical relation on waveform and the space, can obtain a muscle 28 by two cylinders are carried out intersection operation.Then the muscle that obtains along the circumferential direction being repeated to arrange forms many muscle 28, thereby obtains decoupling zero parts 30.
