Description

Technical Field

[0001] This utility model relates to the field of automotive sealing strips, and more particularly to an automotive sealing strip that is easy to replace. Background Technology

[0002] Automotive weatherstripping is a crucial sealing component on a vehicle, playing vital roles in waterproofing, sealing, sound insulation, dustproofing, antifreeze, shock absorption, heat insulation, and energy conservation. It is one of the automotive parts with the largest rubber usage besides tires, primarily used in door frames, windows, hoods, and trunk lids. It effectively prevents rainwater, dust, noise, and other external substances from entering the vehicle, making it an important component for improving vehicle sealing and comfort. Automotive weatherstripping is mainly composed of a metal frame, solid EPDM rubber strips, and foamed EPDM rubber strips.

[0003] As a critical sealing component of the car body, automotive weatherstripping must withstand rain, ultraviolet radiation, temperature changes, and mechanical friction over long periods, making it prone to aging and cracking. While current mainstream automotive weatherstripping has solved problems such as interior odors and poor adhesion between the frame and the adhesive, the replacement process still presents challenges due to its cumbersome installation and difficult replacement methods. Disassembly requires peeling off the double-sided adhesive and then using tools to pry open the clips, making it time-consuming for a single person and difficult for ordinary car owners to perform. Therefore, this application proposes an easy-to-replace automotive weatherstripping to address these technical issues. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-2 The present invention provides an embodiment of an easy-to-replace automotive sealing strip, comprising a main body 1, a skeleton 2 provided on the inner wall of the main body 1, an adhesive strip 3 fixedly connected to the outer wall of the main body 1, a plurality of clamping barbs 5 fixedly connected to the inner side of the main body 1, a mounting seat 6 provided on the bottom side of the main body 1, a plurality of fixing grooves 11 provided at the top of the mounting seat 6, a sealing groove 12 provided at the top of the mounting seat 6, a limiting groove 13 provided in the middle of the mounting seat 6, the inner wall of the mounting seat 6 being connected to the adhesive strip 3 through a fixing component, and an adhesive component provided on the bottom side of the mounting seat 6.

[0017] Specifically, the main body 1 is expanded PTFE, replacing the original foamed rubber to avoid toxic odors in the vehicle. The skeleton 2 is a special polymer skeleton, which is more firmly attached to the main body 1. When using it, first attach the mounting base 6 to the required position using the adhesive components. The fixing components of the mounting base 6 are distributed 30 centimeters apart to fix the main body 1. Then, slide the main body 1 and the adhesive strip 3 into the mounting base 6 along the sealing groove 12, fixing groove 11 and limiting groove 13, and then the installation is complete.

[0018] Reference Figures 2-3 The fixing component includes a connecting block 14 that is slidably connected to the inner wall of the mounting base 6. An unlocking block 7 is fixedly connected to the top side of the connecting block 14, and a clamping block 15 is fixedly connected to the bottom side of the connecting block 14. A limit block 16 is fixedly connected to the middle of the connecting block 14. A spring 17 is provided on the bottom side of the limit block 16. The clamping block 15 is connected to the rubber strip 3. One end of the spring 17 is connected to the limit block 16, and the other end of the spring 17 is connected to the rubber strip 3. Pressing the unlocking block 7 will cause the clamping block 15 on the bottom side of the connecting block 14 to move downward, thereby reducing the fixation of the rubber strip 3 on the outer wall of the main body 1. After installation, the unlocking block 7 is released, and the spring 17 resets the limit block 16, which will then drive the connecting block 14 to work with the clamping block 15 to fix the rubber strip 3 and prevent it from sliding.

[0019] The adhesive assembly includes double-sided adhesive 8 located on the bottom side of the mounting base 6, with a protective film 9 on the bottom side of the double-sided adhesive 8. The outer wall of the protective film 9 has multiple easy-tear teeth 10. When installing the mounting base 6, by bending the mounting base 6, the easy-tear teeth 10 will protrude from the protective film 9, making the protective film 9 easier to peel off, thus exposing the double-sided adhesive 8 on the inside. The mounting base 6 can be installed to the required part of the vehicle through the double-sided adhesive 8. Through the multiple easy-tear teeth 10, the protective film 9 can be easily peeled off from the double-sided adhesive 8 regardless of its position on the mounting base 6.

[0020] The main body 1 has a buffer cavity 4 on the top side to buffer impact. The bottom outer wall of the main body 1 is connected to the sealing groove 12, the outer wall of the rubber strip 3 is connected to the limiting groove 13, the outer wall of the clamping barb 5 is connected to the fixing groove 11, and the main body 1 is connected through multiple mounting grooves opened by the mounting base 6 to form a labyrinth groove, which can prevent rainwater from seeping in.

[0021] Working principle: When in use, by bending the mounting base 6, the easy-tear teeth 10 will protrude from the protective film 9, making the protective film 9 easier to peel off, thus exposing the double-sided adhesive 8 on the inside. The mounting base 6 can be installed to the required part of the vehicle through the double-sided adhesive 8. Then, the main body 1 and the adhesive strip 3 are slid into the mounting base 6 along the sealing groove 12, fixing groove 11 and limiting groove 13. When installing, pressing the unlocking block 7 will drive the clamping block 15 on the bottom side of the connecting block 14 to move downward, thereby reducing the fixation of the adhesive strip 3 on the outer wall of the main body 1. After installation, release the unlocking block 7. The spring 17 will reset the limiting block 16 and drive the connecting block 14 to clamp the adhesive strip 3 to fix it and prevent it from sliding. Then the installation is complete.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
