Referring to fig. 1 and 2, in some alternative embodiments, the guide groove 18 may have a first plane and a second plane substantially parallel to each other in the compression direction of the elastic body 2, wherein the clearance between the first plane and the second plane support may be greater than the height of the guide body 17 in the compression direction of the elastic body 2, that is, the size of the frame 16 is smaller than that of the guide groove 18 in the compression direction of the elastic body 2, and the frame 16 can move relative to the wiper strip 3 along the compression direction of the elastic body 2, so that the wiper strip 3 can adapt to different gaps between the top cover 1 and the glass 5, and simultaneously due to the limitation of the guide groove 18, under the action of the elastic body 2 and the glass 5, the movable range of the framework 16 is limited between the first plane and the second plane, so that the friction surface 4 of the bottom surface of the wiper strip 3 can be always attached to the outer surface of the glass 5, and the wiper strip 3 is prevented from being disconnected from the framework 16.
The principle of the wiper provided by the embodiment of the invention is as follows:
because the bottom of the top cover 1 is fixed with the elastic body 2, and one end of the elastic body 2 far away from the top cover 1 is connected with the wiper strip 3, namely, the gap between the top cover 1 and the wiper strip 3 can be adjusted by compressing the elastic body 2, namely, when the gap between the outer surface of the glass 5 and the top cover 1 is changed, the wiper strip 3 can be ensured to be attached to the glass 5 through the elastic body 2, not only different cambered surfaces of a vehicle glass can be met, but also windshields of various different vehicle types can be adapted to a certain extent, the types of the wiper are reduced, compared with the prior art that an interference amount is left at one end of the wiper strip 3 far away from the top cover 1 to be adapted to the gap between the wiper strip and the glass 5, the friction surface 4 of the bottom surface of the wiper strip 3 can be maintained to be attached to the outer surface of the glass 5 through the elastic body 2, but not attached to the glass 5 through the side bending deformation of the wiper strip 3, because the outer surface of the glass 5 can be adapted to a plane all the time, the side need not be switched in order to adapt to the direction of blowing rain at the in-process of making a round trip to blow rain, the deflection when blowing rain the switching-over reduces by a wide margin, the switching-over abnormal sound that the deformation leads to also can weaken, thereby realize the silence of blowing rain, improve driver's driving experience, therefore, can guarantee through elastomer 2 that the friction surface 4 of wiper strip 3 laminates the surface of glass 5 all the time, accomplish the cleaning work of wiper, improve the clean effect of wiper, simultaneously because the surface of laminating glass 5 has only friction surface 4 always when making a round trip to blow rain, needn't also change the surface of laminating glass 5 when blowing rain switching-over wiper strip 3, the deformation of wiper strip 3 in the switching-over process has been reduced, thereby reduce the abnormal sound when blowing rain the switching-over, improve driver's driving experience.
