Description

Technical Field

[0001] This utility model relates to the field of automotive body technology, and in particular to a wheel arch assembly drainage structure. Background Technology

[0002] Traditional automotive rear wheel arch outer panels are one-piece molded structures. First, the inner wheel arch panel, shock absorber mounting plate, brackets, and other components are welded together to form the rear wheel arch assembly. Then, this assembly is welded to the upper rear section of the side panel inner panel assembly and the side panel outer panel assembly to form the side panel assembly. After welding, the wheel arch outer panel and the side panel outer panel form an inner cavity. Therefore, the fuel filler cap must be designed for external drainage via a sloped surface; otherwise, leakage will occur into the inner cavity due to poor sealing, leading to body corrosion. Furthermore, the external drainage fuel filler cap must have a draft angle of at least 3° in the Y direction, and the distance between the edge of the fuel filler cap mounting hole and the edge of the side panel outer panel must be at least 13mm. Otherwise, molding problems will occur in the side panel outer panel, affecting surface quality. In summary, when the opening size below the fuel filler cap mounting hole is limited, a new structure for external drainage on the inner side of the vehicle body needs to be designed to meet the layout requirements. Utility Model Content

[0003] The purpose of this utility model is to provide a drainage structure for a wheel cover assembly, which solves the drainage problem when the opening size below the fuel filler box mounting hole is limited.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A wheel arch assembly drainage structure includes an inner wheel arch panel, an outer wheel arch panel, and a side panel. A fuel filler pipe mounting bracket is fixedly connected to the lower end of the outer wheel arch panel. A fuel filler port box is fixedly connected to the fuel filler pipe mounting bracket. A drain hole is provided at the bottom of the side of the fuel filler port box facing the inside of the vehicle. The drain hole is used to drain water towards the inside of the vehicle.

[0006] Preferably, in conjunction with the above scheme, a fuel filler sealing box is fixedly connected between the outer side of the wheel arch outer plate and the inner side of the side panel outer plate, and the fuel filler box is disposed in the fuel filler sealing box.

[0007] Preferably, in conjunction with the above scheme, the side of the fuel filler cap sealing box facing the inside of the vehicle is fixedly connected to the fuel filler pipe mounting bracket by welding, and the side of the fuel filler pipe mounting bracket facing the inside of the vehicle is fixedly connected to the wheel arch outer plate by welding.

[0008] Preferably, in conjunction with the above scheme, the side of the refueling pipe mounting bracket extends into a fixed edge, which is fixedly connected to the outer plate of the wheel cover and the refueling port sealing box.

[0009] Preferably, in conjunction with the above scheme, a filler groove is provided on the outer side panel at the opening corresponding to the filler seal box.

[0010] Preferably, in conjunction with the above scheme, the inner wheel cover plate and the outer wheel cover plate are fixedly connected by welding.

[0011] Preferably, in conjunction with the above scheme, the refueling pipe mounting bracket is provided with a refueling pipe mounting hole.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a drainage structure for a wheel arch assembly. When the opening size below the fuel filler cap mounting hole is limited, the existing wheel arch outer panel design can be divided into a wheel arch outer panel and a fuel filler pipe mounting bracket. The wheel arch outer panel and the wheel arch inner panel are sealed with sealant and then welded together, forming a sealed cavity between the inner and outer panels. Since the fuel filler cap is mounted on the fuel filler pipe mounting bracket, and a drainage hole is opened at the bottom of the fuel filler cap, the water accumulated in the fuel filler cap can flow through the drainage hole to the tire direction on the inside of the vehicle body and be discharged outside the vehicle, effectively solving the problems of drainage and layout limitations. At the same time, this utility model has a simple structure, which can reduce the stamping difficulty, reduce the number of modifications to the wheel arch outer panel mold, and reduce the mold development cycle.

[0013] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0021] like Figures 3 to 7The wheel arch assembly drainage structure shown includes an inner wheel arch panel 1, an outer wheel arch panel 2, and a side panel 3. A fuel filler pipe mounting bracket 4 is fixedly connected to the lower end of the outer wheel arch panel 2. A fuel filler port box 5 is fixedly connected to the fuel filler pipe mounting bracket 4. A drain hole 51 is provided at the bottom of the side of the fuel filler port box 5 facing the inside of the vehicle. The drain hole 51 is used to drain water towards the inside of the vehicle and towards the mudguard.

[0022] In order to effectively seal the gap between the outer wheel arch panel 2, the outer side panel 3, and the fuel filler box 5, a fuel filler sealing box 6 is fixedly connected between the outer side of the outer wheel arch panel 2 and the inner side of the outer side panel 3. The gap between the fuel filler sealing box 6 and the outer side panel 3 can be fixed and sealed by expanding adhesive. The fuel filler box 5 is set in the fuel filler sealing box 6.
