[0140] The minimum distance from the end of the decorative inner cavity close to the inner bottom plate 211 to the horizontal plane is greater than the minimum distance from the end of the decorative inner cavity far from the inner bottom plate 211 to the horizontal plane; this design optimizes the utilization of the internal space, and at the same time enhances the overall visual effect, making the decorative body box 201 more layered in appearance.

[0141] The decorative body box 201 is similar to a horn-shaped structure, with a small inner opening and a large outer opening; such a structural design facilitates the actual demolding operation and has various advantages in subsequent use.

[0142] The inner bottom plate 211 is tilted: The tilted setting of the inner bottom plate 211 helps the water to flow toward the external opening under the action of gravity, thereby achieving a better drainage effect.

[0143] The trumpet-like structural design makes it easier for water to be discharged from the external opening after entering the inner cavity of the ornament, thus avoiding water accumulation.

[0144] Inclined inner bottom plate 211: The inclined design of the inner bottom plate 211 not only facilitates drainage, but also reduces the accumulation of debris in the tail throat structure 2, thus keeping the interior clean.

[0145] The trapezoidal structure's internal space design allows debris to slide more easily toward the external opening for easy cleaning.

[0146] Furthermore, a side fog lamp mounting structure 4 is provided on the rear guard body 3 in the present invention; the provision of the side fog lamp mounting structure 4 facilitates the subsequent assembly of the side fog lamps on the entire vehicle, and the side fog lamp mounting structure 4 in the present invention includes a fog lamp mounting groove 41 provided on the rear guard body 3; the fog lamp mounting groove 41 is a through groove structure, which facilitates the subsequent installation of the side fog lamp on the rear guard body 3.

[0147] In the present invention, a fog lamp cover 42 is inserted into the fog lamp assembly groove 41; the fog lamp cover 42 is snapped onto the rear guard body 3; the fog lamp cover 42 essentially serves a decorative purpose. Generally, in low-end models, side fog lamps may not be installed to reduce costs. If the fog lamp assembly groove 41 is exposed, it will not only affect the appearance of the entire vehicle, but also be detrimental to ensuring the overall structural strength of the rear guard body 3.

[0148] Therefore, the present invention designs a fog lamp blocking cover 42 , which is inserted into the fog lamp assembly groove 41 when the rear guard body 3 is not equipped with a side fog lamp, and plays a good blocking role to ensure the integrity of the rear guard body 3 .

[0149] In the present invention, the side fog lamp mounting structure 4 is distributed at the corners of the rear guard body 3; in the present invention, the side fog lamp mounting structure 4 is distributed at the corners of the rear guard body 3; the injection molding shrinkage marks at the corners of the rear guard body 3 can be reduced; at the same time, the side fog lamp mounting structure 4 is distributed at the corners of the rear guard body 3 and can also increase the strength to avoid the rear guard body 3 from breaking at the corners.

[0150] In the present invention, the fog lamp assembly groove 41 is arranged on the rear guard body 3 .

[0151] The fog lamp assembly groove 41 is a through groove structure, and is designed to be a notch that passes through the rear protection body 3 .

[0152] To facilitate the subsequent installation of the side fog lamps, the side fog lamps can be installed on the rear guard body 3 through the assembly groove.

[0153] The fog lamp plug cover 42 is inserted into the fog lamp assembly groove 41; the fog lamp plug cover 42 is fixed on the rear bumper body 3 by a snap connection method.

[0154] In the case of not installing the side fog lamp, the fog lamp plug cover 42 plays a decorative role, plugs the fog lamp assembly groove 41, and ensures the integrity and appearance integrity of the rear bumper body 3.

[0155] The design of the through-groove structure of the fog lamp assembly groove 41 makes the installation of the side fog lamp more convenient, reducing the assembly time and cost.

[0156] The design of the fog lamp plug cover 42 ensures that when the side fog lamp is not installed on the low-equipped vehicle model, the appearance of the rear bumper body 3 is not affected and remains overall beautiful.

[0157] The plugging function of the fog lamp plug cover 42 not only ensures the integrity of the rear bumper body 3, but also enhances the structural strength, avoiding structural weaknesses caused by the exposure of the assembly groove.

[0158] The side fog lamp installation structure 4 is distributed at the corner of the rear bumper body 3, which can reduce the sink marks during the injection molding process and improve the product quality.

[0159] The design of the side fog lamp installation structure 4 can also increase the strength of the corner of the rear bumper body 3, avoiding breakage during use.

[0160] Furthermore, in the present invention, a lower fog lamp installation structure is provided on the lower trim panel 1; the lower fog lamp installation structure includes a lower fog lamp installation groove 12 provided on the lower trim panel 1; the setting of the lower fog lamp installation groove 12 facilitates the through-connection installation of the lower fog lamp on the lower trim panel 1 during actual use, and in the present invention, the lower fog lamp installation groove 12 is a stepped groove; such a setting can achieve the sunken installation of the lower fog lamp on the lower trim panel 1, avoiding the lower fog lamp protruding from the lower trim panel 1.

[0161] Here, the lower fog lamp installation groove 12 is a stepped groove. Mainly, the lower fog lamp installation groove 12 includes a first installation groove and a second installation groove, and the size of the first installation groove is larger than that of the second installation groove. Based on such a setting, the lower fog lamp installation groove 12 can achieve the installation positioning of the lower fog lamp.

[0162] In the present invention, the lower fog lamp installation structure further includes a fog lamp mounting seat 103 provided on the lower trim panel 1; the fog lamp mounting seat 103 is connected to the lower fog lamp to be installed through a fastener; during actual installation, the lower fog lamp is inserted into the lower trim panel 1, and then is connected to the lower trim panel 1 through at least three fog lamp mounting seats 103.

[0163] Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
