Description

Technical Field

[0001] This utility model relates to the field of automotive sealing strips, specifically to a sealing strip for the upper part of a car window. Background Technology

[0002] Sealing strips are products used to seal various items, making them difficult to open, while also providing functions such as shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation. They are widely used in the automotive, electronics, and construction industries.

[0003] When a car is in motion, the gap between the car window glass and the top of the window can easily generate wind noise. Because some existing car windows use a gear and toothed belt to raise the window, the introduction of the toothed belt can easily cause the window glass to drop slightly after contacting the top. This can lead to poor sealing of the conventional upper sealing strip, which can easily cause vibration and increase wind noise. Utility Model Content

[0004] The purpose of this invention is to solve the problem of excessive wind noise caused by vibration in conventional automotive window upper sealing strips. This invention provides a window upper sealing strip that can effectively hold the window glass and reduce the vibration of the window glass and window sheet metal when the vehicle is in motion.

[0005] To achieve the above objectives, this utility model provides a sealing strip for the upper part of a vehicle window, characterized in that it comprises:

[0006] The first clip has a first protruding strip at its bottom end on the side closest to the window glass;

[0007] The second clip is disposed on the side of the first clip away from the window glass to fix the upper sealing strip of the window;

[0008] The third clamping strip is disposed on the side of the first clamping strip near the window glass to form a clamping structure. The clamping structure has a cavity, and a support strip is disposed at the top of the third clamping strip toward the first clamping strip.

[0009] A sound insulation component is disposed inside the cavity. The sound insulation component includes several single strips arranged along the length of the cavity and two connecting strips disposed at both ends of the single strips.

[0010] Preferably, the first clip has a plurality of spaced second protrusions on the side away from the window glass.

[0011] Preferably, at least one extension strip is provided on the side of the second clip near the window glass, and the extension strip is offset downward in a direction away from the second clip.

[0012] Preferably, a third protrusion is provided on the top of the third clip near the window glass.

[0013] Preferably, the top ends of both the first and third clips are configured as arcs offset towards the window glass.

[0014] The above technical solution uses a first and a second clamping strip to fix the sealing strip to the window sheet metal. The first clamping strip, the first protruding strip, the support strip, and the third clamping strip form a stable triangular pressing structure. This allows the third clamping strip to press the window glass closer to the window glass, thereby reducing the vibration amplitude of the window glass. By setting a cavity inside the pressing structure and setting several single strips and connecting strips in the cavity as sound insulation components, the vibration amplitude of the window sheet metal can be further reduced, which can also indirectly reduce the vibration amplitude of the window glass. This effectively reduces wind noise caused by excessive vibration amplitude of the window sheet metal and window glass. Attached Figure Description

[0020] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0021] like Figure 1-3As shown, this utility model provides an upper sealing strip for a vehicle window. The upper sealing strip includes a first clip 1, a second clip 2, a third clip 3, and a sound insulation component. The first clip 1 has a first protrusion 11 at its bottom end near the window glass 9. The second clip 2 is located on the side of the first clip 1 away from the window glass 9 to fix the upper sealing strip. The third clip 3 is located on the side of the first clip 1 near the window glass 9 to form a clamping structure. A cavity 4 is provided in the clamping structure. The top of the third clip 3 extends towards the first clip 1. A support strip 5 is provided, and the sound insulation component is disposed inside the cavity 4. The sound insulation component includes several single strips 6 arranged along the length direction of the cavity 4 and two connecting strips 7 disposed at both ends of the single strips 6. This design uses the first clamping strip 1 and the second clamping strip 2 to fix the upper sealing strip of the vehicle window to the vehicle window sheet metal 8. The first clamping strip 1 and the third clamping strip 3 provide clamping for the vehicle window glass 9. At the same time, a sound insulation component is also provided in the cavity 4 of the clamping structure to reduce wind noise. In some embodiments, the remaining space in the cavity 4 is filled with porous materials, such as sponge, which can further reduce wind noise.

[0022] In the technical solution provided by this utility model, the first clamping strip 1 and the second clamping strip 2 are used to fix the sealing strip to the car window sheet metal 8. The first clamping strip 1, the first protruding strip, the support strip 5 and the third clamping strip 3 form a stable triangular pressing structure, so that the side of the third clamping strip 3 close to the car window glass 9 presses the car window glass 9 to reduce the vibration amplitude of the car window glass 9. By setting a cavity 4 inside the pressing structure, and setting several single strips 6 and connecting strips 7 in the cavity 4 to serve as sound insulation components, the vibration amplitude of the car window sheet metal 8 can be further reduced, and the vibration amplitude of the car window glass 9 can also be indirectly reduced, thereby effectively reducing the wind noise caused by excessive vibration amplitude of the car window sheet metal 8 and the car window glass 9.

[0023] like Figure 1 As shown, the first clamping strip 1 has a plurality of spaced second protrusions 12 on the side away from the window glass 9, and the second clamping strip 2 has at least one extension strip 21 on the side near the window glass 9. The extension strip 21 is offset downward along the direction away from the second clamping strip 2. This design utilizes the cooperation of the second protrusions 12 and the extension strip 21 to achieve a better clamping effect. In some embodiments, an adhesive strip is provided on the side of the second protrusions 12 near the window sheet metal 8 to obtain a better fixing effect.

[0024] According to the technical solution provided by this utility model, a third protrusion 31 is provided at the top of the third clamping strip 3 on the side near the window glass 9. When the upper sealing strip of the window clamps the window glass 9, the side of the third clamping strip 3 away from the window glass 9 is a triangular stable structure, which provides stable support for the third protrusion. In use, it can greatly reduce gaps, thereby reducing wind noise.

[0025] In some embodiments, the top ends of the first clip 1 and the third clip 3 are both set to be arc-shaped and offset towards the window glass 9. This design can reduce the installation difficulty of the upper sealing strip of the window.

[0026] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
