Safety door structure made of PDCPD (Polydicyclopentadiene) material

Abstract

The invention discloses a safety door structure made of a PDCPD (Polydicyclopentadiene) material. The safety door structure comprises a U-shaped reinforcing framework welded at the inner side of an automobile door outer panel and an anti-collision beam which is transversely welded in the middle of the U-shaped reinforcing framework; an outer side reinforcing plate and an inner side reinforcing plate are respectively and transversely welded at the inner and outer sides of the top of the U-shaped reinforcing framework; a gap is formed between the outer side reinforcing plate and the inner side reinforcing plate and is used for mounting automobile door glass; the periphery of the U-shaped reinforcing framework and two ends of the anti-collision beam are respectively fixed with a PDCPD automobile door inner panel through a plurality of auxiliary connecting pieces. According to the safety door structure, the U-shaped reinforcing framework is adopted; the aim of light weight is achieved while the requirements on strength and rigidity of an automobile are met; better energy-saving and environment-friendly performances are realized; the anti-collision beam mainly bears side collision and is used for protecting a living space of a driver, thereby improving the side safety of the automobile. The anti-collision beam adopts a rectangular section; the inside of the anti-collision beam is filled with foamed aluminum so as to enhance the collision energy absorption property; compared with similar materials, the PDCPD material is lighter and higher in strength and rigidity.

AI Technical Summary

Benefits of technology

This patented technology uses special materials for vehicles' doors that are stronger and less expensive compared to older methods like iron or wood panels. These new designs improve their overall performance while reducing weight without compromising on its ability to absorb shock loads effectively during collision events. Additionally, they have better appearance due to being colored black instead of gray white when painted properly. They may include other technical features such as heat dissipation, waterproofness, chemical resistant surfaces, etc., making them ideal for applications where there will be harms caused from accidents involving cars.

Problems solved by technology

This patented describes an issue in vehicle doors where there can be issues such as weight reduction while maintaining sufficient security for passengers or reducing air pollution during operation. Current designs involve multiple layers that require different types of metals like stainless steal laminate, chrome finishes, copper alloys, etc., which leads to increased costs compared to what they were designed without these added features.
