Detailed Implementation
[0032] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.
[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0034] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0035] Example 1
[0036] A tailgate spoiler mounting structure, such as Figures 1-3 As shown, it includes a tailgate assembly 1, a spoiler assembly 2, a connecting component 3, and a cover 4.
[0037] The tailgate assembly 1 includes an outer tailgate panel 11 and an inner tailgate panel 12, with a through hole on the inner tailgate panel 12. The spoiler assembly 2 includes an outer spoiler panel 21 and an inner spoiler panel 22. The connecting component 3 includes a bolt 31 and a nut 32.
[0038] The tailgate outer panel 11 and tailgate inner panel 12 are connected, the spoiler outer panel 21 and spoiler inner panel 22 are connected, the nut 32 is installed on the spoiler inner panel 22, and the bolt 31 can pass through the through hole of the tailgate inner panel 12 and the through hole of the tailgate outer panel 11 and be detachably connected to the nut 32 to realize the connection between the tailgate outer panel 11 and the spoiler inner panel 22. A cover 4 is detachably installed on the through hole.
[0039] Example 2
[0040] A tailgate spoiler mounting structure is provided. In this embodiment, the outer tailgate panel 11 and the inner tailgate panel 12 are plastic parts, connected by tailgate adhesive 13. The outer spoiler panel 21 and the inner spoiler panel 22 are connected by a spoiler connecting structure 23. The connecting assembly 3 also includes a clip 33, which is installed on the inner spoiler panel 22 and can engage with the outer tailgate panel 11. The rest is the same as in embodiment 1.
[0041] Example 3
[0042] A tailgate spoiler mounting structure, the structure of bolt 31 is as follows Figure 4 As shown, an annular limiting structure is provided between the head and the rod of the bolt 31. The diameter of the annular limiting structure is larger than the through hole of the tailgate outer panel 11. When the rod of the bolt 31 passes through the through hole and is threadedly connected to the nut 32, the tailgate outer panel 11 can be clamped by the annular limiting structure and the nut 32.
[0043] Furthermore, in this embodiment, the shielding member 4 is as follows: Figure 5 The cover shown can be detachably engaged with the through hole in the inner panel 12 of the tailgate via a latch. The rest is the same as in Embodiment 2.
[0044] Example 4
