The following description will be made with reference to the specific embodiments of the present invention for further illustrating the matching structure of the fender and the front triangle to help those skilled in the art to understand the technical solution of the present invention more completely, accurately and deeply.

Example 1

The vehicle coordinate system is a special moving coordinate system used for describing the motion of the automobile; the origin of the automobile steering wheel coincides with the center of mass, when the automobile is in a static state on a horizontal road surface, the X axis is parallel to the ground and points to the front of the automobile, the Z axis points to the upper part through the center of mass of the automobile, and the Y axis points to the left side of a driver; the Y-direction surface is a plane parallel to the left-right central symmetry plane of the whole vehicle, the Z-direction surface is a plane parallel to the Y-direction surface and parallel to the plane passing through a longitudinal beam plane or a floor large surface of the vehicle body, and the X-direction surface is perpendicular to the Y-direction surface and the Z-direction surface. DTS means the design standard of clearance, face difference between the automobile body spare part, and the fender of this embodiment shortens size chain ring transfer path with preceding set square cooperation structure, can effectively guarantee fender and preceding set square DTS standard to whole car appearance quality has been promoted. As shown in fig. 1-2, the fender and front triangle mating structure of the present embodiment includes a quarter outer panel 10, a fender mounting bracket 20, a fender 30, and a front triangle 40. As shown in fig. 3, a first via 11, a second via 12, and a third via 13 are disposed on the Y-direction surface of the side wall outer panel 10, and the third via 13 is located above the first via 11 and the second via 12. As shown in fig. 4, the fender mounting bracket 20 comprises a Z-direction fender mounting surface 24 and a Y-direction side wall welding surface 21, wherein the Y-direction side wall welding surface 21 is provided with a main positioning hole 22 and an auxiliary positioning hole 23; the Z-direction fender mounting surface 24 is provided with a nut through hole 25, and the lower surface of the Z-direction fender mounting surface 24 is provided with a projection welding nut 26. As shown in fig. 5, the fender 30 includes an upper edge 32 as a mating surface, and the upper edge 32 is provided with a Z-direction control surface 31. As shown in fig. 6, the front surface 44 of the front triangle 40 serves as a mating surface, and it is an appearance visible surface. The rear surface of the front triangle 40 is provided with a main positioning mounting point 41, a sub positioning mounting point 42 and a Y-direction fixing mounting point 43. The main positioning hole 22 and the auxiliary positioning hole 23 are respectively positioned with the first through hole 11 and the second through hole 12 and weld and fix the Y-direction side wall welding surface 21 and the Y-direction surface of the side wall outer plate 10, the aperture of the first through hole 11 is larger than that of the main positioning hole 22, and the aperture of the second through hole 12 is larger than that of the auxiliary positioning hole 23.
