[0023] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] See also Figures 1 to 5 The utility model provides a supporting structure for a car door strip corner, a car door and a car, including:

[0025] The corner body comprises a connected solid part 1 and a hollow part 2, wherein the hollow part 2 is bent toward the solid part 1, and its two ends are respectively used to connect the first extrusion section 3 and the second extrusion section 4;

[0026] The insert 5 is embedded in the solid part 1, and the insert 5 is attached to the hollow part 2, and a support section 501 is integrally formed at one end thereof. The support section 501 extends in the direction of the first extrusion section 3 so that its periphery is continuously attached to the solid part 1 and the hollow part 2, and is used to support the gap formed between the solid part 1 and the hollow part 2.

[0027] In this embodiment, the corner body includes a connected solid part 1 and a hollow part 2, the solid part 1 is used to fit on the car door, the hollow part 2 is bent in the direction of the solid part 1, and the two ends of the hollow part 2 are respectively used to connect the first extrusion segment 3 and the second extrusion segment 4, which are used to support the corner and the car door so that the corner body and the car door are closely fitted; at the same time, an insert 5 is embedded in the solid part 1, the insert 5 is fitted on the hollow part 2, and a support segment 501 is integrally formed at one end of the hollow part 2, and the support segment 501 extends in the direction of the first extrusion segment 3. The periphery of the support segment 501 is continuously fitted on the solid part 1 and the hollow part 2, which is used to fill the gap formed between the solid part 1 and the hollow part 2, and the position where the door strip corner and the car door are prone to collapse is filled by the support segment 501, so that the position where the corner body is prone to collapse becomes hardened, thereby improving the structural strength of the corner body itself and avoiding the collapse of the door strip corner and the car door.

[0028] The support segment 501 includes a first support area 502 and a second support area 503 connected in sequence. The first support area 502 is an arc-shaped structure for connecting the insert 5 and the second support area 503.

[0029] In this embodiment, the first support area 502 is an arc-shaped structure, and its function is to connect the insert 5 and the second support area 503. The arc-shaped structure is designed to better adapt to the shapes of the solid part 1 and the hollow part 2, and to facilitate giving way to the arc-shaped area of ​​the hollow part 2 to ensure good contact between the support segment 501 and the solid part 1 and the hollow part 2.
