Composite material vehicle door including outer water cutting windowsill beam

Abstract

The invention provides a composite material vehicle door including an outer water cutting windowsill beam. The composite material vehicle door comprises a composite material vehicle door outer plate;a composite material automobile door inner plate; the outer water cutting windowsill beam which is arranged between the composite material automobile door outer plate and the composite material automobile door inner plate, wherein the outer water cutting windowsill beam comprises an outer water cutting windowsill beam body, first connecting structures located at the front end and the rear end of the outer water cutting windowsill beam body and connected with the composite automobile door outer plate, a second connecting structure located at the upper end of the outer water cutting windowsill beam body and connected with the composite automobile door outer plate, and a third connecting structure located at the lower end of the outer water cutting windowsill beam body; and a vehicle door outer handle reinforcing plate which is connected with the outer water cutting windowsill beam through the third connecting structure. According to the composite material vehicle door, various requirements of light weight, diversified shapes, simplified assembly, rapid maintenance development and the like of the whole vehicle provided by the modern vehicle industry are met at the same time.

Description

technical field [0001] The invention relates to the field of automobiles, and more particularly to a composite material vehicle door including an outer water cut sill beam. Background technique [0002] At present, in the traditional vehicle design, whether it is the inner and outer panels of the car door or the bearing parts, steel or aluminum alloy plates are still used for stamping + robot wrapping to connect the inner and outer panels. The steel plate is made of sheet metal. Although it has the advantages of good toughness and high strength, it is too heavy, and there are certain difficulties in disassembly and assembly in the future. Most of the stamping materials are cold rolled plates. If the parts stamped out of cold-rolled steel sheets are often exposed to the air, the surface of the parts is easy to oxidize. When the parts are in use, it takes a lot of time for surface treatment, electrophoresis, and painting. [0003] Now with the development of the automobile ...
