[0023] Reference Figure 1-2 This utility model provides a plug structure for automotive underbody protection plates, comprising:

[0024] The car underbody protection plate 1 has a recessed cover plate recess 11, and the cover plate recess 11 has a maintenance hole 12 in the center. The maintenance hole 12 has a threaded hole 13 and an insertion hole 14 on both sides.

[0025] The cover plate 2 has an installation hole 21 on one side and a cover plate tongue 22 extending outward on the other side. The cover plate tongue 22 is used to be inserted into the insertion hole 14.

[0026] Bolt 3 is used to pass through the mounting hole 21 and connect to the threaded hole 13.

[0027] The maintenance hole 12 of this utility model's plug cover structure is positioned directly opposite the oil leak interface. The maintenance hole 12 is sealed by a removable plug cover plate 2. During installation, the two cover tongues 22 are inserted into the insertion hole 14, and the plug cover plate 2 is moved to the right until the two cover tongues 22 are engaged in the insertion hole 14, aligning the mounting through hole 21 with the threaded hole 13. Then, the bolt 3 is passed through the mounting through hole 21 and connected to the threaded hole 13 to lock the plug cover plate 2 in place. This utility model's plug cover plate 2 is connected to the vehicle's underbody protection plate 1 via the cover tongues 22 and bolts 3, making installation and disassembly convenient. When performing routine maintenance such as oil changes, it is not necessary to completely remove the entire underbody protection plate; only the plug cover plate 2 needs to be removed. This simplifies vehicle maintenance operations, improves maintenance efficiency, and reduces maintenance costs.

[0028] In a preferred embodiment, the threaded hole 13 is formed by riveting the nut 4 into the recessed platform 11 of the cover plate. The underbody protection plate 1 is mostly made of plastic or thin metal sheet. Due to its thinness, the threads formed by direct tapping have shallow profiles and weak load-bearing capacity. Repeated disassembly and reassembly can easily lead to stripping and failure. In contrast, the nut 4 is made of metal, has complete thread profiles, and is firmly connected to the underbody protection plate. It can withstand greater tightening torque and is not limited by the thickness or material of the underbody protection plate.

[0029] As a preferred embodiment, the cover tongue 22 is lower than the plug cover 2, and the two are connected by an arc-shaped transition section. When the two cover tongues 22 are inserted into the insertion hole 14 and the plug cover 2 is moved to the right, the plug cover 2 is in close contact with the cover plate counters 11, and the final arc-shaped transition section abuts against the edge of the insertion hole 14, which can prevent the end of the plug cover 2 from loosening.

[0030] As a preferred embodiment, both the cover plate 2 and the cover plate recess 11 are rectangular and matched in size. After the cover plate 2 is installed, the edge of the cover plate recess 11 limits its movement to prevent translation.

[0031] As a preferred embodiment, the top of the cover plate 2 is fixed with two reinforcing ribs 23 to increase the strength of the cover plate 2.

[0032] In a preferred embodiment, the number of cover tongues 22 is two.

[0033] As a preferred embodiment, the bolt 3 is a hexagonal flange bolt, which is easy to tighten and can press the cover plate 2 on top.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
