Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a silent wiper strip. Background Art

[0002] The wiper is an important accessory installed on the windshield of the car, and the wiper strip is an important part of the wiper. The wiper strip is tightly attached to the windshield and reciprocates on the windshield, thereby sweeping away the rain, snow and dust on the windshield that obstruct the view.

[0003] The wiper strip is a solid body as a whole, and its sections have the same structure along the length direction of the wiper strip. The width of the connecting strip 1 between the support arm 1 and the support arm 2, and the width of the connecting strip 2 between the support arm 2 and the support arm 3 of the existing wiper strip are mostly the same, so that when the wiper portion of the wiper strip tilts once during operation, the bending order of the connecting strip 1 and the connecting strip 2 is not fixed, resulting in the contact order of the support arm 1 with the support arm 2, and the contact order of the support arm 2 with the support arm 3 is not fixed, which not only generates a large noise, but also affects the service life of the wiper strip. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology and provide a silent wiper strip.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is a silent wiper strip: comprising a mounting portion and a wiper portion, the wiper strip is mounted on the wiper through the mounting portion, the wiper portion comprises a triangular rubber strip knife, a support arm one arranged on both sides of the lower portion of the triangular rubber strip knife, a connecting portion one is provided at the lower end of the wiper portion, a support arm two is symmetrically provided on both sides at a lower end of the connecting portion, a connecting portion two is provided at the lower end of the support arm two, a support arm three is symmetrically provided on both sides at the lower end of the connecting portion two, a connecting portion three is provided at the lower end of the support arm three, the connecting portion three is connected to the mounting portion, and the wiper strip is integrally formed; the width of the connecting portion one is greater than the width of the connecting portion two.

[0006] Furthermore, one end of the support arm is inclined downward.

[0007] Furthermore, the length relationship among the support arm 1, support arm 2 and support arm 3 is as follows: when the wiper portion tilts to one side, the end of the support arm 1 abuts against the support arm 2, and the end of the support arm 2 abuts against the support arm 3.

[0008] Furthermore, the length relationship among the support arm one, support arm two and support arm three is as follows: when the wiper portion tilts to one side, the end of the support arm one abuts against the support arm three, and the end of the support arm two abuts against the support arm three.

[0009] Furthermore, the groove formed between the second support arm and the third support arm is inclined upward.

[0010] The advantages of the present invention compared with the prior art are: the present invention designs the width of the connection part one to be greater than the width of the connection part two, so that when the wiper is tilted in one direction, the connection part two is bent first, so that the end of the second support arm is first in contact with the support arm three, and then the connection part one is bent, so that the end of the one support arm is in contact with the second support arm or the third support arm, thereby ensuring that the tilting angle of the connection part two is smaller than that of the traditional wiper, the movement is regular, and a slight sound is generated, which is close to silent. At the same time, it is not easy to be damaged and has a long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] Embodiment 1, in combination with Figure 1-2A silent wiper strip comprises a mounting portion 1 and a wiper portion 2, wherein the wiper strip is mounted on a wiper through the mounting portion 1, the wiper portion 2 comprises a triangular rubber blade 3, and support arms 4 are arranged on both sides of the lower portion of the triangular rubber blade 3, a connecting portion 5 is arranged at the lower end of the wiper portion 2, support arms 6 are symmetrically arranged at the lower end of the connecting portion 5 on both sides, a connecting portion 2 7 is arranged at the lower end of the support arm 2 6, support arms 3 8 are symmetrically arranged at the lower end of the connecting portion 2 7 on both sides, a connecting portion 3 9 is arranged at the lower end of the support arm 3 8, the connecting portion 3 9 is connected to the mounting portion 1, and the wiper strip is integrally formed; the width of the connecting portion 5 is greater than the width of the connecting portion 2 7.
