Abstract

The invention provides an automobile doorsill which is good in stamping performance and high in sealing performance. The bottom of the automobile doorsill is high in corrosion prevention performance. The automobile doorsill structurally comprises a side wall shell plate and a doorsill body, the section of the side wall shell plate is 'C'-shaped, the side wall shell plate and the doorsill body are relatively fixedly welded to form a cavity structure, the section of the cavity structure is 'square', a plurality of wedge-shaped bosses are arranged among the lower portion of the doorsill body and welded edges of the side wall shell plate, and leaking liquid holes are arranged on the wedge-shaped bosses. The wedge-shaped bosses are formed on the lower portion of a doorsill assembly and can realize effects of reinforcing ribs and rebounding ribs, so that the rigidity and the strength of the doorsill assembly are improved, and the wedge-shaped bosses are favorable for stamping of the doorsill assembly. Besides, the leaking liquid holes are arranged on the wedge-shaped bosses, difficulty in spraying sealants at the bottom of the doorsill is reduced, working hours and consumption of the sealants are also reduced, and the sealing performance of a cavity of the doorsill is improved.

Description

technical field [0001] The invention relates to the technical field of automobile body-in-white manufacturing, in particular to an automobile threshold. Background technique [0002] The threshold is a key component in the body-in-white, which has an important impact on the stiffness, strength and crash performance of the vehicle. The sill structure is usually welded by the side wall outer panel and the sill body, and its cross-section is in the shape of a "mouth"; the lower welding edges of the two are of the same size, and the welding edge of the sill assembly is a straight line. In the currently developed sill structure, the sill body is easy to rebound, and there are many installation holes and process holes; at the same time, in order to ensure the coating effect, many leakage bosses are set up. The bottom of the vehicle is often affected by harsh environments such as stone impact, sewage, dust, etc., and the protection requirements are relatively high. The lower par...
