[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] like Figures 1 to 5 As shown, this embodiment provides a sealing strip structure for a frameless car door, which includes a plastic bracket 1 and a snap-fit ​​component 2. The plastic bracket 1 has a snap-fit ​​structure 11 with a guide 12, allowing the sealing strip to be installed. The snap-fit ​​component 2 has a first snap-fit ​​cavity 21, a second snap-fit ​​cavity 22, and a snap-fit ​​hole 23. The snap-fit ​​hole 23 communicates with the first snap-fit ​​cavity 21. The snap-fit ​​structure 11 snaps into the first snap-fit ​​cavity 21. The guide 12 is located within the snap-fit ​​hole 23 and engages with it. The opening direction of the first snap-fit ​​cavity 21 is opposite to that of the second snap-fit ​​cavity 22, allowing the second snap-fit ​​cavity 22 to snap into automotive sheet metal parts.

[0030] The sealing strip structure for frameless car doors provided by this invention involves snapping the snap-fit ​​structure 11 into the first snap-fit ​​cavity 21, while the guide member 12 is positioned within the snap-fit ​​hole 23 and engages with it. This arrangement enhances the snap-fit ​​strength between the snap-fit ​​member 2 and the plastic bracket 1, preventing them from detaching. Furthermore, the second snap-fit ​​cavity 22 is snapped into the automotive sheet metal, further strengthening the snap-fit ​​strength between the sealing strip and the sheet metal. This sealing strip structure for frameless car doors effectively solves the problem of detachment between the sealing strip and the automotive sheet metal when using spring clips in the prior art.

[0031] In some embodiments, the guide member 12 includes, but is not limited to, a guide block, wherein the guide block has a guide surface 121, which is inclined toward the direction away from the opening of the first snap-fit ​​cavity 21. This configuration allows the guide surface 121 to act as a guide when the snap-fit ​​structure 11 and the first snap-fit ​​cavity 21 are snapped together, facilitating installation.

[0032] In this embodiment, the sidewall of the snap-fit ​​hole 23 has an anti-rotation surface 231, wherein the anti-rotation surface 231 is matched with the sidewall of the guide member 12 to limit the rotation of the snap-fit ​​member 2, thereby preventing it from falling off the plastic bracket 1 and further ensuring the snap-fit ​​strength between the snap-fit ​​member 2 and the plastic bracket 1.

[0033] In some embodiments, the anti-rotation surface 231 is, but is not limited to, a plane. This allows the plane to engage with the sidewall of the guide member 12, preventing the snap-fit ​​member 2 from rotating.

[0034] In some embodiments, the snap-fit ​​component 2 includes a snap-fit ​​plate 24 and a first bent plate 25 and a second bent plate 26 connected to both ends of the snap-fit ​​plate 24. A first snap-fit ​​cavity 21 is formed between the snap-fit ​​plate 24 and the first bent plate 25, and a second snap-fit ​​cavity 22 is formed between the snap-fit ​​plate 24 and the second bent plate 26. The first bent plate 25 has snap-fit ​​holes 23. This configuration allows the snap-fit ​​component 2 to engage with the first snap-fit ​​cavity 21 formed between the snap-fit ​​plate 24 and the first bent plate 25, and to engage with the automotive sheet metal through the second snap-fit ​​cavity 22 formed between the snap-fit ​​plate 24 and the second bent plate 26.

[0035] Furthermore, the snap-fit ​​plate 24 has a first barb 241, wherein the first barb 241 extends toward the first bent plate 25, and can abut against the plastic bracket 1 through the first barb 241, further enhancing the snap-fit ​​strength between the snap-fit ​​plate 24 and the snap-fit ​​structure 11.

[0036] Similarly, the second bending plate 26 has a second barb 261, which extends toward the snap-fit ​​plate 24. The second barb 261 can abut against the automotive sheet metal parts. This arrangement can enhance the snap-fit ​​strength between the automotive sheet metal parts and the snap-fit ​​parts 2.

[0037] In this embodiment, both the first barb 241 and the second barb 261 are V-shaped. This enhances the connection strength between the snap-fit ​​component 2, the snap-fit ​​structure 11, and the automotive sheet metal.

[0038] In some embodiments, there are multiple snap-fit ​​structures 11 and multiple snap-fit ​​elements 2, wherein the multiple snap-fit ​​structures 11 are distributed at intervals along the length direction of the plastic bracket 1, and the multiple snap-fit ​​structures 11 and multiple snap-fit ​​elements 2 are arranged in a one-to-one correspondence. This arrangement can further enhance the snap-fit ​​strength between the plastic bracket 1 and the automotive sheet metal.

[0039] This embodiment also provides an automobile, including the sealing strip structure described above. Using the automobile provided by this invention, the snap-fit ​​structure 11 is snapped into the first snap-fit ​​cavity 21, while the guide member 12 is located within the snap-fit ​​hole 23 and engages with it. This arrangement improves the snap-fit ​​strength between the snap-fit ​​member 2 and the plastic bracket 1, ensuring that the snap-fit ​​member 2 and the plastic bracket 1 will not detach. Furthermore, the second snap-fit ​​cavity 22 is snapped into the automobile sheet metal, further enhancing the snap-fit ​​strength between the sealing strip and the automobile sheet metal. The automobile using this invention effectively solves the problem in the prior art where the sealing strip and the automobile sheet metal easily detach when snapped together using spring clips.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
