The side wall of axis is connected, and the side wall of second boss is connected with the side wall of rear shaft.Since each position of windshield has centainly
Curvature varying, therefore side protecting cover 3 can the generation turn of opposite central skeleton 1 with the variation of the curvature of windshield in stroke
It is dynamic, if first boss 6 and second boss during rotation departing from the front-rear side walls of central skeleton 1, then position limiting structure
Limit effect will lose effect, and therefore, the side wall of first boss 6 is connected with the side wall of front rotary shaft, and the side wall of second boss is with after
The side wall efficiency of shaft, strong ensure that first boss 6 and second boss always can be with the front-rear side walls phases of central skeleton 1
It supports, then limit effect is by continuous and effective.Preferably, the quantity of first boss 6 is four, and four first boss 6 are rotating around preceding
Shaft is uniformly distributed, and the quantity of second boss is also four, and four second boss are uniformly distributed rotating around rear shaft.
Preferably, as shown in figure 4, on the front-rear side walls of the end for being connected with side protecting cover 3 of rain shaving blade 2
Equipped with the card slot 7 that length extends in left-right direction, side protecting cover 3 is set there are two being respectively used to the card being mutually clamped with two clamp bar slots 7
Son 8.By the cooperation of clamp 8 and card slot 7 to fix rain shaving blade 2, assembly is simple, is easy to grasp.
Preferably, side protecting cover 3 is equipped with third boss 9, third boss 9 is located between two clamps 8, and third is convex
Platform 9 is against on the upper wall of rain shaving blade 2.By the effect of third boss 9, increases side protecting cover 3 and the local support of rain shaving blade 2 is imitated
Fruit makes to blow rain effect more preferable.
Preferably, further including the left branch 10 being located between two side protecting covers 3 and right point as shown in Figure 2 and Figure 5
Branch 11, left branch 10 and right branch 11 arc protruding upward in middle part；Left part of the middle part of left branch 10 with central skeleton 1
Hingedly, the both ends of left branch 10 are connected with rain shaving blade 2；The middle part of right branch 11 is hinged with the right part of central skeleton 1, right branch 11
Both ends be connected with rain shaving blade 2.By the effect of left branch 10 and right branch 11, increases the supporting point to rain shaving blade 2, be to blow rain
Effect is more preferable.Preferably, the left part of central skeleton 1 is equipped with mounting hole 15, and left branch 10 is equipped with opposite with the mounting hole 15
The matching hole answered, central skeleton 1 and left branch 10 are connected by passing through mounting hole 15 with branch's shaft 16 that matching hole matches,
Similarly, the articulated form of right branch 11 is identical as left branch 10.
Preferably, the hinge joint of left branch 10 and central skeleton 1 is equipped with the rotation model for limiting left branch 10
The left latch closure 12 enclosed；The hinge joint of right branch 11 and central skeleton 1 is equipped with the right side for limiting the slewing area of right branch 11
Latch closure 13.Pass through the slewing area of effect the limitation left branch 10 and right branch 11 of latch closure.
Preferably, connector includes the central protecting cover 14 to match with central skeleton 1 and is located at central protecting cover 14
On interconnecting piece, central protecting cover 14 is covered on central skeleton 1.Preferably, the section of central protecting cover 14 and side protecting cover 3 is equal
It is streamlined, windage when high vehicle speeds is reduced, oil consumption is reduced.Preferably, side protecting cover 3 is made of plastics, and is conducive to
The lightweight of vehicle.
The principle of the present embodiment is, is that first boss 6 and second is convex in the present embodiment by the setting of position limiting structure
Platform, first boss 6 and second boss are against respectively on the front-rear side walls of central skeleton 1, effectively prevent shaft 4 in through-hole 5
Axial float occurs；Increase the supporting point to rain shaving blade 2 by the effect of left branch 10 and right branch 11, so that rain shaving blade 2
Each section be more uniformly stressed, avoid because the discontinuity in each portion of rain shaving blade 2 and bring is scraped windscreen wiper and is not done
Only, tend to have and remain water stain problem, therefore, this windscreen wiper to blow rain effect preferable.
The beneficial effects of the utility model are, by position limiting structure to limit axial movement of the shaft 4 in through-hole 5,
To prevent side protecting cover 3 from axial float occurs with central skeleton 1 place that is hinged, effectively avoiding windscreen wiper, to blow rain effect bad
The problem of；Increase the supporting point to rain shaving blade 2 by the effect of left branch 10 and right branch 11, so that each portion of rain shaving blade 2
That divides is more uniformly stressed.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be right
