Description

Technical Field

[0001] This utility model relates to the field of automotive water barrier technology, specifically a silicone water barrier strip for automobiles. Background Technology

[0002] Most car sunroofs now come with built-in sealing strips, and silicone rubber is often chosen as the primary material for these sealing strips because of its excellent heat resistance and weather resistance. These properties stem from the flexibility and chemical inertness of the silicone rubber molecular structure. Compared to ethylene propylene diene monomer (EPDM) or polyvinyl chloride (PVC), silicone rubber is less prone to hardening or cracking under prolonged exposure to sunlight, effectively maintaining its sealing performance. It is especially widely used in high-end vehicles.

[0003] Some products add a self-adhesive layer to connect with the sunroof frame. Although this design can effectively seal the car sunroof, after long-term use, the corners may still come unglued, resulting in a failure to prevent rainwater from entering the car. Utility Model Content

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] Please see Figures 1-3 It includes a rubber strip 1, with a waterproof component 2 at the top of the rubber strip 1 to prevent rainwater from entering the vehicle, and a connecting component 3 at the bottom of the rubber strip 1 for connecting with the car sunroof.

[0025] The connecting component 3 includes a connecting silicone 301 installed at the bottom of the adhesive strip 1. The top of the connecting silicone 301 is fixedly connected to the middle line of the bottom of the adhesive strip 1. The height of the connecting silicone 301 is h3, and the length of the height h3 is 4 mm. One end of the connecting silicone 301 is fixedly connected to a pointed tip 302. The width of the pointed tip 302 is the same as the width of the connecting silicone 301, which is a2. The length of the width a2 is 4 mm. The bottom of the adhesive strip 1 is fixedly connected to two abutting adhesives 4, which are symmetrically installed on the middle line of the adhesive strip 1.

[0026] The outer wall of the pointed tip 302 is symmetrically equipped with a snap-fit ​​area 303, and the snap-fit ​​area 303 is designed to be inclined. The angle between the snap-fit ​​area 303 and the pointed tip 302 is b, and the degree b is 45°.

[0027] The length between the two contact areas 303 is a3, and the length a3 is 4.6 mm;

[0028] The thickness of the adhesive strip 1 is h2, and the height of the thickness h2 is 2 mm.

[0029] When installation is required, the user pinches the silicone strip body. Due to the elasticity of the silicone strip, it contracts, facilitating subsequent installation. At this time, pushing the guide head 201 moves the filler 202, which in turn moves the silicone strip 1. The silicone strip 1 then moves the connecting silicone 301, which in turn moves the pointed tip 302. The pointed tip 302 then moves the two locking areas 303. Simultaneously, the silicone strip 1 moves the two abutting adhesives 4. When the desired position is reached, the rebound of the abutting adhesives 4... The adhesive 4 abuts against the bottom of the window frame, which in turn moves the adhesive strip 1. The adhesive strip 1 abuts against the filler adhesive 202, which in turn moves the guide head 201, the connecting silicone 301, the connecting silicone 301, the pointed head 302, and the pointed head 302. The snap-fit ​​area 303 moves, thus snapping the window frame with one snap-fit ​​and the window glass with the other snap-fit ​​area 303. This effectively increases waterproofing and prevents rainwater from seeping into the car through gaps.
