"Below," "under," and "below" the first feature in relation to the second feature includes the first feature directly below and diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[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 2 As shown, this embodiment provides a sealing strip for a frameless car door side panel. The sealing strip includes a sealing skeleton 1, a sealing adhesive layer 2, and a sealing lip 3. The sealing skeleton 1 can be connected to the side panel plastic trim 4; the sealing adhesive layer 2 wraps around the sealing skeleton 1 and can adhere to the side panel plastic trim 4; the sealing lip 3 is connected to the sealing adhesive layer 2 and can abut against the door glass 5; wherein the sealing skeleton 1, the sealing adhesive layer 2, and the sealing lip 3 are a co-extruded integral structure.

[0030] The sealing strip for frameless car door side panels provided by this utility model eliminates the problems of installation difficulties and poor matching appearance caused by the prior art, where the sealing skeleton 1 needs to be installed with the sealing adhesive layer 2 and sealing lip 3 after being rolled and formed. With the sealing strip for frameless car door side panels of this utility model, after the sealing skeleton 1 is rolled and formed, the sealing skeleton 1, sealing adhesive layer 2 and sealing lip 3 can be extruded into an integral structure. This design eliminates the need to install the sealing skeleton 1 with the sealing adhesive layer 2 and sealing lip 3 again, and it can be directly connected to the side panel plastic trim 4. The installation is simple and convenient, and it effectively solves the problems of installation difficulties and poor matching appearance between the sealing strip and the side panel plastic trim 4 in the prior art.

[0031] In some embodiments, both the sealant layer 2 and the sealing lip 3 are made of rubber, and the hardness of the sealant layer 2 is greater than that of the sealing lip 3. This design ensures that the sealant layer 2 does not deform significantly when it is attached to the side plastic trim 4, thus guaranteeing a good seal. The sealing lip 3, being less hard than the sealant layer 2, is more prone to deformation, preventing damage to the door glass 5.

[0032] Furthermore, the materials of the sealant layer 2 and the sealing lip 3 include, but are not limited to, EPDM rubber or thermoplastic vulcanized rubber. Among them, EPDM rubber has strong UV resistance and elasticity; thermoplastic vulcanized rubber has strong oil resistance and service life.

[0033] In this embodiment, the shapes of the sealing frame 1 and the sealing layer 2 match the shape of the side plastic outer trim 4. This arrangement allows for a better match between the sealing frame 1, the sealing layer 2, and the side plastic outer trim 4, improving aesthetics.

[0034] In some embodiments, the sealing frame 1 includes a first frame 11 and a second frame 12 connected to each other. The first frame 11 and the second frame 12 are perpendicular to each other to match the shape of the side panel plastic trim 4 and to connect the first frame 11 to the side panel plastic trim 4. This improves the connection strength between the sealing strip for the frameless door side panel and the side panel plastic trim 4.

[0035] In this embodiment, the first frame 11 and the side plastic outer trim 4 are riveted together. The riveting connection method has a high sealing effect and connection strength.

[0036] Alternatively, the first frame 11 and the side plastic trim 4 can be connected by screws, which can also ensure a high sealing effect and connection strength.

[0037] Alternatively, the first frame 11 and the side plastic exterior trim 4 can be snapped together, which facilitates installation and disassembly.

[0038] In some embodiments, the sealing lip 3 includes a first lip 31 and a second lip 32 connected to each other. The first lip 31 is connected to the sealant layer 2, and the second lip 32 is capable of abutting against the door glass 5. This facilitates abutting against the door glass 5.

[0039] Specifically, the sealing frame 1 is made of metal. This ensures the structural strength of the sealing strip used for the side panels of frameless doors.

[0040] This embodiment also provides a frameless car door, including the sealing strip for the side panel of the frameless car door as described above. The frameless car door provided by this invention eliminates the problems of installation difficulties and poor matching appearance caused by the prior art where, after the sealing frame 1 is rolled and formed, it still needs to be installed with the sealing layer 2 and the sealing lip 3. With the frameless car door of this invention, after the sealing frame 1 is rolled and formed, the sealing frame 1, the sealing layer 2, and the sealing lip 3 can be extruded together into an integral structure. This eliminates the need to install the sealing frame 1 with the sealing layer 2 and the sealing lip 3 again, allowing direct connection to the side panel plastic trim 4. Installation is simple and convenient, effectively solving the problems of installation difficulties and poor matching appearance between the sealing strip and the side panel plastic trim 4 in the prior art.

[0041] It should be noted that the manufacturing process of the sealing strip used for the side panel of the frameless car door is as follows: the metal sealing skeleton 1 is rolled into shape and then extruded together with the sealing adhesive layer 2 and the sealing lip 3 into an integral structure; then the sealing skeleton 1 is bent to make it consistent with the upper curvature of the side panel plastic outer trim 4.

[0042] This embodiment also provides an automobile, including the frameless door described in the above-mentioned solution. The automobile using this invention eliminates the problem in the prior art where, after the sealing frame 1 is rolled and formed, it still needs to be installed with the sealing layer 2 and the sealing lip 3, leading to installation difficulties and poor matching appearance. With this invention, after the sealing frame 1 is rolled and formed, the sealing frame 1, the sealing layer 2, and the sealing lip 3 can be extruded together into an integral structure. This eliminates the need to install the sealing frame 1 with the sealing layer 2 and the sealing lip 3 again, allowing direct connection to the side plastic exterior trim 4. Installation is simple and convenient, effectively solving the problems of installation difficulties and poor matching appearance between the sealing strip and the side plastic exterior trim 4 in the prior art.

[0043] 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.
