Thus, when assembling the rear bumper assembly 4 and the rear apron assembly, the rear bumper buckle 421 can be aligned with the rear apron buckle hole, and when embedded in the rear apron buckle hole, the rear bumper buckle 421 deforms. Thus, after penetrating the rear apron buckle hole, the rear bumper buckle 421 restores the deformation and forms a clamping connection with the first rear bumper support.

[0073] Thus, the clamping connection between the first rear bumper support 2 and the limiting support 42 can limit the assembly of the rear bumper assembly 4 and the rear apron assembly at the middle position, improving the assembly efficiency. When assembling the rear bumper assembly 4 and the rear apron assembly, the clamping connection between the first rear bumper support 2 and the limiting support 42 can be completed in advance, so that the rear bumper assembly 4 and the rear apron assembly can be positioned in the Y direction during assembly.

[0074] One or more utility model embodiments, the rear bumper limiting structure 4101 includes a rear bumper limiting hole for embedding a rear apron limiting boss of the rear apron assembly to limit the rear bumper assembly 4. Or, the rear bumper limiting structure 4101 includes a rear bumper limiting boss embedded in a rear apron limiting hole formed on the rear apron assembly to limit the rear bumper assembly 4.

[0075] The rear apron limiting structure 32 can include at least one rear apron limiting boss, and if the rear apron limiting boss is at least two, at least two rear apron limiting bosses are distributed along the length direction of the second support body 31, for example, at least two rear apron limiting bosses are distributed on both sides of the guide flange 33.

The limiting space 301 and the connecting structure 21 as a whole limit the assembly of the rear bumper assembly 4 and the rear apron assembly in Z direction. Therefore, the assembly of the rear bumper assembly 4 and the rear apron assembly is completed, and the assembly efficiency of the rear bumper assembly 4 is improved.

[0076] In one or more embodiments, the rear apron limiting structure 32 can include at least one rear apron limiting hole, and if the rear apron limiting hole is at least two, at least two rear apron limiting holes are distributed along the length direction of the second support body 31, for example, at least two rear apron limiting holes are distributed on both sides of the guide flange 33. Correspondingly, the rear bumper assembly 4 is provided with a rear bumper limiting boss, and when the rear bumper assembly 4 is inserted into the limiting space 301, the rear bumper limiting boss is close to the rear apron limiting hole. Wherein, the edge of the rear apron limiting hole close to the rear apron limiting boss is deformed under the pressure of the rear apron limiting boss, so that the rear apron limiting boss enters the rear bumper limiting hole, and the assembly limiting of the rear bumper assembly 4 and the rear apron assembly in X direction is formed. The limiting space 301 and the connecting structure 21 as a whole limit the assembly of the rear bumper assembly 4 and the rear apron assembly in Z direction. Therefore, the assembly of the rear bumper assembly 4 and the rear apron assembly is completed, and the assembly efficiency of the rear bumper assembly 4 is improved.

[0077] In summary, through the cooperation of the boss and the limiting hole structure, the position limitation of the rear bumper assembly 4 and the rear apron assembly on both sides can be realized, so that the assembly efficiency can be improved.

[0078] During the assembly of the rear bumper assembly 4 and the rear apron assembly, the rear bumper assembly 4 can be pushed along the X direction and lifted to the highest point along the rear apron limiting boss, which is the highest installation point of the rear bumper assembly 4. When the rear bumper limiting hole corresponding to the rear bumper assembly 4 is lower than the guide flange 33, the installation is not a problem; when the rear bumper limiting hole corresponding to the rear bumper assembly 4 is higher than the guide flange 33, the installation is difficult. Thus, the assembly height difference and the assembly accuracy can be accurately checked.

[0079] In summary, the utility model discloses an embodiment of a kind of rear apron assembly and vehicle, the rear apron assembly can include rear apron outer plate 1, rear bumper first support 2 and two rear bumper second supports 3, the rear bumper first support 2 is fixed on the rear apron outer plate 1, connection structure 21 is provided on the rear bumper first support 2, to be connected with the limiting support 42 of rear bumper assembly 4. Two rear bumper second supports 3 are distributed on the two sides of the rear bumper second support 3, wherein the rear bumper second support 3 includes second support body 31, at least two rear apron limiting structures 32 and guide flange 33, the second support body 31 is connected with the rear apron outer plate 1, the rear apron limiting structure 32 is provided on the second support body 31, and cooperates with rear bumper limiting structure 4101 of rear bumper assembly 4, to limit the position of the rear apron outer plate 1 and rear bumper assembly 4. The guide flange 33 extends outward from the second support body 31, and a limiting space 301 is formed between the second support body 31 to limit the rear bumper assembly 4 inserted into the limiting space 301. Through the connection of the rear bumper first support 2 and the limiting support 42 of the rear bumper assembly 4, the cooperation of the rear apron limiting structure 32 on the rear bumper second support 3 and the rear bumper limiting structure 4101 of the rear bumper assembly 4, and the limiting space 301 formed by the guide flange 33 on the rear bumper second support 3 for the insertion of the rear bumper assembly 4, the assembly of the rear apron assembly and the rear bumper assembly 4 is realized.
