Automobile doorsill protective plate mounting structure

Abstract

The invention relates to an automobile doorsill protective plate mounting structure which comprises a doorsill protective plate body, wherein a doorsill protective plate decorative strip is welded on the front surface of the doorsill protective plate body, a plurality of decorative strip welding wings are arranged at the periphery of the doorsill protective plate decorative strip which is welded with the doorsill protective plate body by virtue of the decorative strip welding wings to form an integral body; a plurality of buckling bases are arranged on the back surface of the doorsill protective plate body at intervals; metal buckles are arranged on the buckle bases; the metal buckles are connected to a metal plate. Mounting points of the doorsill and the metal plate are distributed on the doorsill protective plate body below the decorative strip, the doorsill protective plate body is welded with the decorative strip to form a doorsill protective plate decorative assembly, and then the doorsill assembly is integrally arranged on the metal plate, so that the mounting strength is greatly improved, the mould structure is simplified, the used and maintenance costs for a mould are reduced, the product qualified rate is increased, the production cost is lowered, the finished product competitiveness is increased, and the profits of the automobile enterprises are increased.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to an installation structure of an automobile door sill guard plate. Background technique [0002] At present, the traditional installation structure of the car door sill guard plate is completed by the card seat that grows on the inner surface of the door sill through plastic clamping, which leads to the following problems: [0003] (1) The installation strength of the sill plate is insufficient. [0004] (2) Due to the layout of the card seat and the inner surface of the A-pillar, it is easy to cause sink marks on the outer surface, which will affect the appearance quality of the door sill guard. [0005] (3) Due to the lack of core-pulling space inside the sill guard body, the strength of the mold is directly insufficient and the service life is short. [0006] (4) The threshold is a force-bearing part. After a long period of trampling, the plastic clips are prone to f...
