Abstract

The utility model provides a rubber strip of making an uproar falls that uses on wiper, includes the wiper body, and this wiper body includes fixed part, windscreen wiper portion and connects the fulcrum portion between fixed part and windscreen wiper portion, forms the swing groove between this fixed part and the windscreen wiper portion, still includes a plurality of lugs of interval arrangement in proper order along wiper body length direction to this a plurality of lugs are established on the opposite face between fixed part and the windscreen wiper portion. The noise reduction rubber strip has the advantages that the structural design is ideal, the design of the plurality of lugs on the opposite surfaces between the fixing portion and the wiper portion is adopted, and in the process of swinging back and forth left and right of the wiper blade, the original surface-to-surface contact mode between the bottom surface of the wiper portion and the top surface of the fixing portion is changed into the point-to-surface contact mode, so that the contact area between the bottom surface of the wiper portion and the top surface of the fixing portion is reduced, the noise is greatly reduced, and the noise reduction rubber strip has the effect. Due to the existence of the collision effect of the plurality of convex blocks, the deformation amplitude of the wiper part during left-right back-and-forth swinging is reduced, the fulcrum part is not easy to damage, and the service life of the wiper rubber strip is prolonged.

Description

Noise reduction adhesive tape used on windscreen wiper

Technical Field

The utility model relates to a wiper specifically indicates the adhesive tape of making an uproar that falls that uses on the wiper.

Background

A wiper, also known as a wiper, a wiper blade, or a windshield wiper, is a device for wiping off raindrops and dust attached to a windshield of a vehicle, so as to improve visibility of a driver and increase driving safety. The windscreen wiper is a sheet type structure arranged in front of a windshield and comprises a motor, a speed reducer, a connecting rod mechanism, a wiper arm mandrel, a wiper rubber strip and the like. Taking a wiper strip as an example, the existing wiper strip generally includes a wiper body, the wiper body includes a fixing portion, a wiper portion and a fulcrum portion connected between the fixing portion and the wiper portion, and a swing groove is formed between the fixing portion and the wiper portion. When the wiper rubber strip works, the wiper blade on the wiper part can swing back and forth left and right by taking the fulcrum part as a center, so that the wiping operation of rain spots and dust on the windshield of the vehicle is realized. The existing windscreen wiper rubber strip is not ideal in structural design, and the contact area between the bottom surface of the windscreen wiper part and the top surface of the fixed part is large in the process that the windscreen wiper part of the windscreen wiper body swings left and right back and forth, so that noise is easy to generate; and the deformation amplitude of the left-right back-and-forth swing of the wiper part is large, the fulcrum part is easy to damage, and the service life of the wiper rubber strip is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a rubber strip of making an uproar falls that uses on wiper, its aim at mainly overcome current windscreen wiper adhesive tape structural design ideal inadequately, produce the noise easily, fulcrum portion harms easily moreover, influences shortcomings such as life of windscreen wiper adhesive tape.

In order to solve the technical problem, the technical scheme of the utility model as follows:

the utility model provides a rubber strip of making an uproar falls that uses on wiper, includes the wiper body, and this wiper body includes fixed part, windscreen wiper portion and connects the fulcrum portion between fixed part and windscreen wiper portion, forms the swing groove between this fixed part and the windscreen wiper portion, still includes a plurality of lugs of interval arrangement in proper order along wiper body length direction to this a plurality of lugs are established on the opposite face between fixed part and the windscreen wiper portion.

Furthermore, the side edge of the fixing part is provided with a groove for clamping the windscreen wiper support, and the plurality of bumps are arranged on the top surface of the fixing part.

Further, the plurality of convex blocks are divided into two rows, and the two rows of convex blocks are symmetrically arranged left and right by taking the fulcrum parts as central lines.

Further, the plurality of bumps and the fixing portion are integrally formed.

Further, the wiper portion is provided with a main wiper blade at the top thereof and left and right sub wiper blades at both sides of the bottom thereof.

Further, each bump is in a strip shape.

From the above description of the present invention, compared with the prior art, the advantages of the present invention lie in: the noise reduction rubber strip has the advantages that the structural design is ideal, the design of the plurality of lugs on the opposite surfaces between the fixing portion and the wiper portion is adopted, and in the process of swinging back and forth left and right of the wiper blade, the original surface-to-surface contact mode between the bottom surface of the wiper portion and the top surface of the fixing portion is changed into the point-to-surface contact mode, so that the contact area between the bottom surface of the wiper portion and the top surface of the fixing portion is reduced, the noise is greatly reduced, and the noise reduction rubber strip has the effect. And the existence of a plurality of lug conflict effects for the deformation range when windscreen wiper portion back and forth swing reduces, and fulcrum portion is difficult to damage, has improved the life of windscreen wiper adhesive tape.

Detailed Description

The following describes a specific embodiment of the present invention with reference to fig. 1 to 4.

Reference is made to figures 1, 2 and 3. A noise reduction rubber strip used on a windscreen wiper comprises a windscreen wiper body 1, wherein the windscreen wiper body 1 comprises a fixing part 10, a windscreen wiper part 11 and a fulcrum part 12 connected between the fixing part 10 and the windscreen wiper part 11, and a swing groove 13 is formed between the fixing part 10 and the windscreen wiper part 11; the windscreen wiper further comprises a plurality of bumps 2 which are sequentially arranged at intervals along the length direction of the windscreen wiper body 1, and the bumps 2 are arranged on the opposite surfaces between the fixing part 10 and the windscreen wiper part 11.

Reference is made to figures 1, 2 and 3. The side of fixed part 10 is seted up and is used for going into the recess 14 of going into the wiper support, a plurality of lugs 2 are established on the top surface 100 of fixed part 10, and every lug 2 is the bar form, and the outer tip of every lug 2 outwards extends and is close to the border department to fixed part 10 top surface 100. The plurality of convex blocks 2 are divided into two rows, the two rows of convex blocks are symmetrically arranged at left and right sides by taking the fulcrum part 12 as a central line, and the convex blocks at each row are arranged at equal intervals. The plurality of projections 2 and the fixing portion 10 are integrally formed. The wiper portion 11 is provided with a main wiper blade 110 at the top thereof and left and right

sub wiper blades

111 and 112 at both sides of the bottom thereof.

In addition, the plurality of bumps 2 may also be disposed on the bottom surface of the wiper portion 11, which may specifically refer to fig. 4 of the specification; the plurality of bumps 2 may also be respectively disposed on the bottom surface of the wiper portion 11 and the top surface 100 of the fixing portion 10 in a one-to-one correspondence manner, so that the original surface-to-surface contact manner between the bottom surface of the wiper portion 11 and the top surface of the fixing portion 10 is changed into a point-to-point contact manner, and thus the contact area between the two is smaller, and the effect of reducing noise is further improved.

The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
