DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present utility model will be further described below with reference to the accompanying drawings:

[0024] In the paragraphs of the detailed description, the orientation nouns involved are only for the convenience of those skilled in the art to understand the technical solutions recorded in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, terms such as "set", "installed", "connected", etc. should be understood in a broad sense. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0025] As Figures 1 to 4 shown, an installation structure of an automobile wheel arch sealing strip includes a door body 100, a wheel arch sealing strip 200, and an exterior wheel arch 300. A first fixing hole 101 is provided on one side of the door body 100, a second fixing hole 102 is provided on the other side, and a fixing through hole 103 is also provided that penetrates from one side to the other side; the wheel arch sealing strip 200 is arranged on one side of the door body 100 and is fixedly connected to the first fixing hole 101; the exterior wheel arch 300 is arranged on the other side of the door body 100 and is fixedly connected to the second fixing hole 102; wherein, a plurality of fixing screws 201 are further provided on the wheel arch sealing strip 200, and one end of the fixing screw 201 passes through the door body 100 and is fixedly connected to the exterior wheel arch 300. In this way, after the wheel arch sealing strip 200 and the exterior wheel arch 300 are respectively abutted against and fixed to the door body 100, the wheel arch sealing strip 200 and the exterior wheel arch 300 are on the same straight line as the fixing through hole 103, that is, the wheel arch sealing strip 200 and the exterior wheel arch 300 share a fixing point, which not only improves the fitting degree of the wheel arch sealing strip 200, the exterior wheel arch 300 and the door body 100, but also improves the connection strength and stability between the two and the door body 100.

[0026] As Figure 5 shown, a collapse groove 202 is provided at one end of the wheel arch sealing strip 200. In this way, when the collapse groove 202 of the wheel arch sealing strip 200 is subjected to an external force, its two sides will deform and collapse inward, thereby improving the sealing performance between the door body 100 and the vehicle body on the premise of ensuring that the closing of the door body 100 is not affected.

[0027] As Figure 5 shown, a plurality of first buckles 203 are installed on the side wall of the end of the wheel arch sealing strip 200 away from the collapse groove 202, and the buckles protrude to the other side of the wheel arch sealing strip 200 and are connected to the first fixing hole 101. In this way, the wheel arch sealing strip 200 not only plays a positioning role but also a preliminary fixing role through the plurality of first buckles 203. This makes the assembly process of the wheel arch sealing strip 200 more convenient and more accurate.

[0028] As Figure 5As shown, mounting holes 204 penetrating from one side to the other side of the wheel arch seal strip 200 are respectively provided at both ends of the first buckle 203, and are adapted to the fixing screws 201. In this way, through the positioning and preliminary fixing of the first buckle 203, the mounting holes 204 can be accurately adapted to the fixing through holes 103 to ensure that the two are on the same straight line, facilitating the connection of the fixing screws 201.

[0029] As Figure 6 shown, a plurality of bosses 301 are provided on the side of the exterior wheel arch 300 facing the door body 100, and second buckles 302 adapted to the second fixing holes 102 are embedded at the ends of some of the bosses 301. In this way, the second buckles 302 are similar in function to the first buckles 203 and are used for the positioning and preliminary fixing of the exterior wheel arch 300 and the door body 100.

[0030] As Figure 6 shown, positioning posts 303 are provided at the ends of the bosses 301 adjacent to the second buckles 302, and the positioning posts 303 are adaptively connected to the second fixing holes 102. In this way, the exterior wheel arch 300 can assist in the connection between the second buckles 302 and the door body 100 through the positioning posts 303, so that the second buckles 302 can be accurately and quickly connected to the door body 100.

[0031] As Figure 6 shown, spring nut 304 is installed at the end of the boss 301 adjacent to the positioning post 303, and spring nut 304 is also installed in the fixing through hole 103 opposite thereto. In this way, through the cooperation of the second buckle 302 and the positioning post 303, the spring nut 304 on the positioning post 303 and the spring nut 304 in the fixing pupil can be on the same straight line for connection with the fixing screw 201.

[0032] As Figure 7 and Figure 8 shown, the mounting holes 204, the fixing through holes 103, and the bosses 301 opposite to the fixing through holes 103 are on the same straight line and are connected by fixing screws 201. In this way, the three are on the same straight line, enabling the wheel arch seal strip 200 and the exterior wheel arch 300 to share a fixing point for connection and fixation with the door body 100. Thus, compared with the traditional fixing method, the connection strength and connection stability between the wheel arch seal strip 200 and the exterior wheel arch 300 and the door body 100 are effectively improved, making it less likely for the wheel arch seal strip 200 and the exterior wheel arch 300 to displace or fall off from the door body 100 under harsh working conditions.

[0033] Finally, although this specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
