Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and in particular relates to an automobile front baffle assembly structure. Background Art

[0002] In the process of implementing the utility model, the inventor found that the prior art has at least the following problems:

[0003] The front fender of a car is usually an independent sheet metal with a large area, spanning the entire front of the car in the Y direction. In order to facilitate stamping, the structure is relatively simple, but in general, the front fender is thin, and is mainly connected to surrounding parts by MIG welding. The sheet metal thickness is about 0.7 to 1.2 mm, and the strength is relatively low. At present, SPR is partially used to connect the front fender reinforcement plate to increase the strength, but for the WCBS (brake system) product, which is more powerful and relatively heavy, the local mode of the front fender is only 37.3HZ, which is far from the design requirements, and the rigidity is poor and easy to deform.

[0004] CN101913381A-A car front fender assembly structure discloses a car front fender assembly structure, including a front fender, wherein a plurality of mounting areas are provided on the front fender, a mounting area is provided with mounting holes, a mounting area is provided with bosses, and the bosses are formed by deformation of the plate material of the front fender. By adopting the above technical solution, bosses are provided for all mounting areas of the front fender to play the role of reinforcing ribs; reinforcing ribs are also provided for planes with larger areas to optimize the structure of the front fender body; adding crossbeams and longitudinal beams on the front fender cannot solve the above technical problems.
