[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0035] like Figures 1-8 As shown, this embodiment discloses a car tailgate buffer assembly, which is used in conjunction with a car body sheet 1. It includes a base 2, and a limiting part 23 is provided on the outer periphery of the base 2. The car body sheet 1 is provided with a limiting hole 11 with a limiting plate 12 corresponding to the limiting part 23. The limiting part 23 includes a guide protrusion 23a. When the base 2 is screwed into the limiting hole, the guide protrusion 23a restricts the limiting plate 12 from moving out.

[0036] Combination Figures 2-3 As shown, the car tailgate buffer assembly in this embodiment includes a base 2 and a buffer cap 3. The inner hole of the base 2 has an internal thread 21, and the buffer cap 3 has an external thread 31 that mates with it. By adjusting the helix angle between the buffer cap 3 and the base 2, the height of the buffer cap 3 can be precisely adjusted to accommodate the gaps of different car tailgates. This design provides a flexible height adjustment method, ensuring that the device is compatible with various car models and improving its versatility and adaptability.

[0037] Furthermore, combined Figures 4-6 As shown, in this embodiment, two limiting parts 23 are symmetrically provided on the outer periphery of the base 2. The limiting part 23 further includes an abutting shoulder 23b and a limiting protrusion 23c. The guiding protrusion 23a, the abutting shoulder 23b and the limiting protrusion 23c all protrude from the outer periphery of the base 2, and the three together form a groove structure. When the base 2 is connected to the body sheet metal 1, the limiting plate 12 is located in the groove.

[0038] Furthermore, combined Figure 8 As shown, in this embodiment, the body sheet metal 1 has a roughly circular limiting hole 11. The inner edge of the limiting hole 11 extends inward to form a limiting plate 12. The limiting plate 12 is divided into four equal parts and spaced apart. The roughly circular limiting hole 11 is a toothed circular hole structure.

[0039] Further, in the embodiment, the guide protrusion 23a is obliquely arranged along the axial direction of the base 2, and the guide protrusion 23a is located on the outer circumferential surface of the base 2, and the abutting protrusion 23b is an arc-shaped protrusion arranged along the circumferential direction of the base 2. An annular groove 26 is arranged on the outer circumferential surface of the base 2, and the annular groove 26 is used to connect one end of the dustproof sleeve 22, and the other end of the dustproof sleeve 22 is a free end. When the base 2 is installed on the vehicle body panel 1, the free end of the dustproof sleeve 22 is tightly attached to the surface of the vehicle body panel 1 to play a dustproof and waterproof role. One side of the annular groove 26 has a shoulder 25 protruding from the outer circumferential surface of the base 2, and the shoulder 25 is close to the abutting protrusion 23b. The limiting protrusion 23c connects the shoulder 25 and the abutting protrusion 23b as a whole, and when the base 2 is installed in place on the vehicle body panel 1, the side edge of the limiting plate 12 close to the abutting protrusion 23b is tightly attached to the abutting protrusion 23b.

[0040] Further, in the embodiment, a part of the guide protrusion 23a protrudes from the abutting protrusion 23b, that is, the guide protrusion 23a, the abutting protrusion 23b, and the limiting protrusion 23c form a generally V-shaped cross section, wherein the height of the guide protrusion 23a protruding from the abutting protrusion 23b along the axial direction of the base 2 is lower than the height of the limiting protrusion 23c protruding from the abutting protrusion 23b along the axial direction of the base 2. For example, in the embodiment, the clockwise rotation of the base 2 is the installation direction, and the counterclockwise rotation of the base 2 is the disassembly direction. The clockwise limiting of the base 2 allows the limiting plate 12 to be clamped into the groove structure formed by the guide protrusion 23a, the abutting protrusion 23b, and the limiting protrusion 23c. The limiting protrusion 23c functions to prevent the limiting plate 12 from being separated from the groove structure when the base 2 is continuously rotated clockwise. When the base 2 is rotated counterclockwise, the guide protrusion 23a limits the rotation of the base 2 to a certain extent, and a greater force is required to rotate the base 2 out, that is, the rotation force of the base 2 out is greater than the rotation force of the base 2 in.

[0041] Specifically, referring to FIG. 2, Figure 5 As shown in FIG. 2, a guide portion 24 is arranged between each two adjacent limiting portions 23, and the guide portion 24 is used to guide the base 2 to move relative to the vehicle body panel 1 in the direction of rotation in and / or rotation out; the guide portion 24 has a first guide surface 24a, which is in contact with the limiting plate 12 and guides the base 2 to rotate into the vehicle body panel 1. The guide portion 24 has a second guide surface 24b, which is in contact with the limiting plate 12 and guides the base 2 to rotate out of the vehicle body panel 1.

[0042] Further, in the embodiment, two guide portions 24 are arranged on the outer periphery of the base 2, and the two guide portions 24 are staggered with the two limiting portions 23. The first guide surface 24a and the second guide surface 24b are symmetrically arranged on each guide portion 24, wherein the first guide surface 24a is in contact with the limiting plate 12, and is used for guiding the base 2 to move in the screwing-in direction and smoothly embed into the vehicle body panel 1; the second guide surface 24b is also in contact with the limiting plate 12, and is used for guiding the base 2 to stably separate from the connecting position when the base 2 is screwed out.

[0044] In some other embodiments, an automobile is disclosed, which comprises the back door system described in some other embodiments.
