[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] See also Figure 1-5 The utility model provides a technical solution: an automobile sealing strip with a snap-fit structure, comprising a sealing strip body 1 and an automobile connecting portion 5, a waterproof spacer 2 is provided on the sealing strip body 1, the number of the waterproof spacer 2 is two, an arc-shaped card groove 101 is provided on the sealing strip body 1, and an arc-shaped card block 501 is provided on the automobile connecting portion 5. The arc-shaped card block 501 cooperates with the arc-shaped card groove 101, which can facilitate the snap-fitting between the sealing strip body 1 and the automobile connecting portion 5, thereby improving the fixing effect of the sealing strip body 1. The sealing strip body 1 is provided with a card slot for accommodating the sealing strip body 1. Groove 102, there are two accommodating grooves 102, and a bending plate 4 is matched in the accommodating groove 102. The bending plate 4 is a long copper metal sheet, which can improve the bending effect of the sealing strip body 1 and facilitate the installation of the sealing strip body 1. An arc-shaped buffer plate 6 is provided on the top of the sealing strip body 1. A buffer chamber 601 is provided between the top of the sealing strip body 1 and the arc-shaped buffer plate 6. The arc-shaped buffer plate 6 is an arc-shaped elastic rubber sheet, which can effectively protect the sealing strip body 1, prevent the car door from squeezing the sealing strip body 1, and improve the service life of the sealing strip body 1.
[0024] The automobile connecting portion 5 is provided with positioning grooves 502 . The positioning grooves 502 are arranged in two rows, and each row contains three positioning grooves 502 .
[0025] The waterproof isolation member 2 includes a base plate 201, on which an elastic inclined plate 202 is provided. The elastic inclined plate 202 is inclined at a forty-five degree angle to the base plate 201. The elastic inclined plate 202 is an elastic rubber sheet, which can ensure that the elastic inclined plate 202 and the automobile connection part 5 are tightly fitted. There are seven elastic inclined plates 202, and a sealing gasket 2021 is provided on the elastic inclined plate 202. The sealing gasket 2021 contacts the surface of the automobile connection part 5. The surface of the sealing gasket 2021 has rubber protrusions, which can increase the friction between the elastic inclined plate 202 and the automobile connection part 5, thereby improving the fixing effect of the sealing strip body 1.
[0026] When installing the sealing strip body 1, align the arc-shaped card groove 101 on the sealing strip body 1 with the arc-shaped card block 501 on the automobile connecting part 5, and then press the sealing strip body 1 onto the automobile connecting part 5 so that the arc-shaped card block 501 is stuck in the arc-shaped card groove 101. In the process of pressing the sealing strip body 1 onto the automobile connecting part 5, the waterproof spacers 2 arranged on both sides of the sealing strip body 1 are in contact with the surface of the automobile connecting part 5 respectively. The extrusion generated by the waterproof spacers 2 and the automobile connecting part 5 causes the elastic inclined plate 202 on the waterproof spacer 2 to undergo elastic bending deformation, so that the inclined angle between the elastic inclined plate 202 and the bottom plate 201 becomes smaller, and the elastic inclined plate The rebound force generated by the elastic deformation of 202 makes the sealing gasket 2021 on the elastic inclined plate 202 fit tightly with the surface of the automobile connecting part 5, thereby making the seven elastic inclined plates 202 of the two waterproof isolation parts 2 fit tightly with the automobile connecting part 5. When the sealing strip body 1 ages due to long-term use, the gap between the waterproof isolation part 2 and the automobile connecting part 5 is filled by the rebound of the elastic inclined plate 202, so that the elastic inclined plate 202 still fits tightly with the surface of the automobile connecting part 5. Through the seven elastic inclined plates 202 on the waterproof isolation part 2, the sealing strip body 1 has a seven-fold protection function, which greatly enhances the sealing and waterproof properties of the sealing strip body 1.
[0027] An elastic cavity tube 3 is provided on the sealing strip body 1. The elastic cavity tube 3 is an elastic rubber cavity tube body, which can ensure the elastic deformation effect of the elastic cavity tube 3. The number of elastic cavity tubes 3 is two rows, and the number of elastic cavity tubes 3 in one row is three. A positioning protrusion 301 is provided on the elastic cavity tube 3, and the positioning protrusion 301 cooperates with the positioning groove 502.
[0028] During the installation of the sealing strip body 1, the automobile connecting part 5 contacts the two rows of elastic cavity tubes 3 provided on the sealing strip body 1 and makes the positioning protrusions 301 on the elastic cavity tubes 3 snap into the corresponding positioning grooves 502 on the automobile connecting part 5. Since the gap between the two rows of elastic cavity tubes 3 is much smaller than the width of the position where the automobile connecting part 5 is snapped into the inner part of the sealing strip body 1, the automobile connecting part 5 squeezes the elastic cavity tubes 3. The squeezing force generated causes the elastic cavity tubes 3 to be flattened and elastically deformed. The rebound force generated by the compression of the elastic cavity tubes 3 makes the elastic cavity tubes 3 fit tightly with the surface of the automobile connecting part 5. When the sealing strip body 1 ages due to long-term use, the elastic cavity tubes 3 have elasticity, so that the elastic cavity tubes 3 still maintain a tight fit with the surface of the automobile connecting part 5 after rebounding, so that the tube cavities of the two rows of elastic cavity tubes 3 still have a good sound insulation effect.
