Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive sealing strip applications, specifically a lip used to eliminate abnormal noise when the glass is lowered. Background Technology
[0002] Window seals are an important component of every car. They prevent water, dust, and other pollutants from entering the vehicle. In addition, window seals help keep the interior clean and dry, play a crucial role in controlling temperature changes inside the car, and also isolate external noise from the windows.
[0003] After the window sealing strip is installed, based on the single-rail lift door, the glass will only stop rising after it rises to the top and triggers a stall force. This force will cause the glass to deflect outwards, eventually causing the inner wall of the small lip to contact and be squeezed together with the small pillar. When the glass falls, the inner wall of the small lip will separate from the small pillar, making an abnormal noise, which will affect the customer's use. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a lip for eliminating abnormal noise when glass is lowered, so as to solve the technical problems mentioned in the background above.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a lip for eliminating abnormal noise when the glass is lowered, comprising an outer side of the car door, an inner side of the car door, an inner mounting groove for the car window, and a car window glass. A car window sealing strip is installed inside the inner mounting groove for the car window, and the car window sealing strip is composed of a sealing strip body, a small lip, and a small post. A sealing sheet is provided on the side of the small post, and PE cotton is installed on the outside of the sealing sheet.
[0006] By adopting the above technical solution, multiple sets of inclined sealing plates are set inside the sealing strip body for installing PE cotton. The PE cotton can then isolate the small lip and the small pillar, thus preventing them from contacting each other, eliminating adhesion and abnormal noise, and improving the user experience. Since multiple sets of sealing plates are inclined inside the sealing strip body, the PE cotton has a larger area when wrapping multiple sets of sealing plates. The PE cotton has the function of absorbing noise, which can reduce the noise of friction between the car window glass and the small lip.
[0007] The present invention is further configured such that the window sealing strip is movably installed inside the mounting groove inside the window, and the window sealing strip is engaged between the outer side of the door and the inner side of the door.
[0008] By adopting the above technical solution, the window sealing strip can be used to seal the window glass and isolate water, dust and noise from the inside and outside of the vehicle.
[0009] The present invention is further configured such that the window glass is fitted inside the sealing strip body, and the sealing strip body is used to seal both sides of the window glass.
[0010] By adopting the above technical solution, and by setting a window sealing strip, the window glass is fitted into the interior of the sealing strip body, and the sealing strip body can play a sealing role for the window glass.
[0011] The present invention is further configured such that multiple sets of sealing sheets are provided, and PE cotton is installed on the outside of the multiple sets of sealing sheets, which can isolate noise.
[0012] By adopting the above technical solution and setting multiple sets of sealing sheets, not only can they be used to support the installation of PE cotton, thus increasing the installation area of PE cotton, but they also help PE cotton absorb noise from the car window glass.
[0013] The present invention is further configured such that multiple sets of sealing sheets are inclined, and the included angle between the sealing sheets and the small column is less than 90°.
[0014] By adopting the above technical solution, and by setting multiple sets of sealing strips at an angle, the PE cotton can be better applied when the car window glass is lowered. The gaps between the multiple sets of sealing strips do not affect the lowering of the car window glass.
[0015] The present invention is further configured such that the window sealing strip and the sealing sheet are made of EPDM material, and the window sealing strip and the sealing sheet are injection molded as a whole.
[0016] By adopting the above technical solution and setting EPDM rubber strips, EPDM material has high strength and high flexibility.
[0017] In summary, the present invention has the following main advantages:
[0018] This invention uses multiple sets of inclined sealing sheets inside the sealing strip body to install PE cotton. The PE cotton can then isolate the small lip and the small pillar, preventing them from contacting each other, eliminating adhesion and noise, and improving the user experience. Since multiple sets of sealing sheets are inclined inside the sealing strip body, the PE cotton has a larger surface area when wrapping around these sealing sheets. The PE cotton also absorbs noise, reducing the noise from friction between the car window glass and the small lip. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0028] The following describes an embodiment of the present invention based on its overall structure.
[0029] A type of lip used to eliminate rattling noise when glass is lowered, such as Figure 1-7 As shown, the vehicle includes an outer side of the door 1, an inner side of the door 2, an inner window mounting groove 3, and a window glass 4. A window sealing strip 5 is installed inside the inner window mounting groove 3. The window sealing strip 5 consists of a sealing strip body 501, a small lip 502, and a small pillar 503. A sealing sheet 6 is provided on the side of the small pillar 503, and PE cotton 7 is installed on the outside of the sealing sheet 6. By setting multiple sets of inclined sealing sheets 6 inside the sealing strip body 501 for installing PE cotton 7, the PE cotton 7 can isolate the small lip 502 and the small pillar 503, thereby preventing the small lip 502 and the small pillar 503 from contacting each other, eliminating adhesion and abnormal noise, and improving the user experience. Since multiple sets of sealing sheets 6 are inclined inside the sealing strip body 501, the PE cotton 7 has a larger area when wrapping multiple sets of sealing sheets 6. The PE cotton 7 has the function of absorbing noise and can reduce the noise of friction between the window glass 4 and the small lip 502.
[0030] Please see Figure 1The window sealing strip 5 is movably installed inside the window mounting groove 3, and the window sealing strip 5 is engaged between the outer side 1 and the inner side 2 of the door. By setting the window sealing strip 5, it can be used to seal the window glass 4 and isolate water, dust and noise from the inside and outside of the car.
[0031] Please see Figure 3 The window glass 4 is fitted inside the sealing strip body 501. The sealing strip body 501 is used to seal both sides of the window glass 4. By setting the window sealing strip 5, the window glass 4 is fitted inside the sealing strip body 501, and the sealing strip body 501 can play a sealing role for the window glass 4.
[0032] Please see Figure 4 Multiple sets of sealing sheets 6 are provided, and PE cotton 7 is installed on the outside of multiple sets of sealing sheets 6. PE cotton 7 can isolate noise. By setting multiple sets of sealing sheets 6, not only can they be used to support the installation of PE cotton 7, but the installation area of PE cotton 7 is also increased, which helps PE cotton 7 absorb noise from the car window glass 4.
[0033] Please see Figure 4 Multiple sets of sealing sheets 6 are set at an angle, and the included angle between the sealing sheet 6 and the small column 503 is less than 90°. By setting multiple sets of sealing sheets 6 at an angle, the PE cotton 7 can be better applied when the window glass 4 is lowered. There are gaps between the multiple sets of sealing sheets 6, so as not to affect the lowering of the window glass 4.
[0034] Please see Figure 1 The window sealing strip 5 and sealing sheet 6 are made of EPDM material, and the window sealing strip 5 and sealing sheet 6 are injection molded into a whole. By setting the rubber strip of EPDM material, the EPDM material has high strength and high flexibility.
[0035] The working principle of this utility model is as follows: First, the operator installs the window sealing strip 5 into the inner mounting groove 3 of the window, and the window sealing strip 5 is engaged between the outer side 1 and the inner side 2 of the door. Then, when the user opens and closes the window glass 4, the rise or fall of the window glass 4 will cause the small lip 502 to move. The PE cotton 7 is located between the small lip 502 and the small pillar 503. Thus, the PE cotton 7 can isolate the small lip 502 and the small pillar 503, thereby eliminating the sticky noise between the small lip 502 and the small pillar 503. When the window glass 4 falls, it will act on the PE cotton 7, and the noise generated by the friction between the window glass 4 and the window sealing strip 5 will be absorbed by the PE cotton 7, thereby reducing the noise generation and improving the user experience.
