Further, the second connecting portion front section is provided with the avoidance portion of upwarping, and the avoidance portion is fixedly connected with the bending portion.
The beneficial effects are that: the bottom surface height difference of the avoidance part bottom surface and the second connecting part is greater than or equal to the thickness of the bending part, so that the second bending part is attached to the mounting part, and the welded structural strength is further ensured.
Further, the bicycle frame comprises a front hub shroud, wherein the front hub shroud is fixedly connected with the upper surface of the front longitudinal beam of the bicycle frame, and the bottom surface of the bending part is fixedly connected with the upper surface of the front hub shroud.
The beneficial effects are that: a frame with high rigidity is formed by the front longitudinal beam, the automobile front coaming and the front hub shroud, so that the overall strength of the automobile body is improved.
Further, a connecting plate is arranged between the automobile front coaming and the front hub shroud, one side of the connecting plate is fixedly connected with the front longitudinal beam of the frame, and the other side of the connecting plate is bent upwards and supports the front hub shroud.
The beneficial effects are that: utilize the connecting plate to support preceding hub shroud to the force that receives preceding hub shroud and the coaming before the car is transmitted to the frame front longitudinal beam, and then transmits to automobile body suspension installing support, and the coaming atress is too big before avoiding the car, leads to the coaming fracture before the car, improves the security of car.
