The advantage is that through the cooperation between the waterproof strip 12 and the positioning groove 11, a stable whole can be formed between the baffle 4, the waterproof strip 12 and other components, thereby enhancing the structural strength of the sealing plug, reducing deformation and loosening during use, and improving the overall sealing and stability.

[0028] Specifically, the waterproof strip 10 is made of one of ethylene propylene diene monomer rubber EPDM, chloroprene rubber CR, silicone rubber and polyvinyl chloride PVC, and the waterproof strip 2 12 is made of one of butyl rubber, foamed polyurethane and rubber-plastic blended materials. The advantage is that the design of the waterproof strip 10 can adapt to extreme temperature conditions in high and low temperature environments, and can effectively enhance the service life of the overall sealing component 1. The design of the waterproof strip 2 12 can not only improve the sealing performance of the overall sealing component 1, but also reduce noise.

[0029] Specifically, the edges of the seal 1, the baffle 4, the waterproof strip 10 and the waterproof strip 12 are all designed with arc-shaped chamfers, and two identical slots 13 are provided. The two slots 13 are symmetrically distributed about the center line of the seal 1. The advantage is that the arc-shaped chamfer design can make the contact between the seal 1, the baffle 4, the waterproof strip 10 and the waterproof strip 12 and the vehicle door tighter and smoother, reducing the problem of loose sealing caused by sharp edges, further improving the overall sealing performance, and the design of the two slots 13 also facilitates the installation of the seal 1 and the vehicle door.

[0030] Working principle: When in use, the multi-bump combination design of the bump 1 8 and the bump 2 9 can increase the support points of the seal 1 in contact with the vehicle door, so that the seal 1 is not easily displaced or deformed when subjected to external force, and maintains a stable sealing state. The design of the reinforcement area 2 of the cross-shaped structure can provide support and stability in multiple directions. When opening and closing the vehicle door, it can effectively resist the impact and extrusion generated when the door is opened and closed, thereby improving the durability of the seal 1. The design of the recessed area 1 3 can change the stress distribution of the reinforcement area 2 to avoid stress concentration and make the force more uniform. The design of the recessed area 2 7 can provide avoidance space for other structures without increasing the overall volume, making the layout of the seal 1 more reasonable and compact. The arc-shaped chamfer can reduce sharp edges and reduce scratches on personnel during installation, maintenance or use. Or the risk of stabbing, through the cooperation of the waterproof strip 2 12 and the positioning groove 11, the baffle strip 4, the waterproof strip 2 12 and other components can form a stable whole, thereby enhancing the structural strength of the sealing plug, reducing deformation and loosening during use, and improving the overall sealing and stability. Through the design of the waterproof strip 10, it can adapt to extreme temperature conditions in high and low temperature environments, and can effectively enhance the service life of the overall seal 1. The design of the waterproof strip 2 12 can not only improve the sealing of the overall seal 1, but also reduce noise. The arc chamfer design can make the contact between the seal 1, the baffle strip 4, the waterproof strip 10 and the waterproof strip 2 12 and the vehicle door closer and smoother, reducing the problem of loose sealing caused by edges and corners, and further improving the overall sealing performance. The design of the two slots 13 also facilitates the installation of the seal 1 and the vehicle door.
