Modularized vehicle door with steel, aluminum and plastic mixed

Abstract

The invention relates to a modularized vehicle door with steel, aluminum and plastic mixed. Compared with a total complex structure of a traditional vehicle door, according to the modularized vehicle door with steel, aluminum and plastic mixed, the original complex vehicle door structure is modularized, and the vehicle door structure is divided into three functional modules which include a vehicle door outer plate, a vehicle door frame, a vehicle door inner plate and an accessory module. According to the functionality of all parts of the vehicle door, traditional vehicle door modules are functionalized, and good vehicle door manufacturing and assembling manufacturability is achieved. The modularized vehicle door with steel, aluminum and plastic mixed is specifically characterized in that the vehicle door outer plate is not a main stressed part in the vehicle door structure, the strength and rigidity requirements are moderate, and the purpose generally lies in the effect that the functional requirements for meeting external shapes are improved; the vehicle door inner plate is not a main stressed part, either, and can be made of composite materials or plastic. According to the modularized vehicle door with steel, aluminum and plastic mixed, factors in all the aspects of strength, rigidity, appearance and weight are taken into comprehensive consideration, the vehicle door outer plate can be made of thinner metal material plates and aluminum alloy materials, and the aluminum alloy materials are light, small in specific gravity, high in strength, good in ductility, and high in corrosion resistance and meanwhile has good forming performance, machinability and the like.

Description

technical field [0001] The invention relates to a vehicle body door assembly, in particular to a steel-aluminum-plastic mixed modular vehicle door, which belongs to the technical field of vehicle design and manufacture. Background technique [0002] The car body is one of the three major assemblies of the car and occupies an extremely important position in the car design. The car door is an important part of the side wall of the car body, and directly affects the appearance and safety of the car. The design of the car door is extremely important. The traditional car door structure usually consists of three parts: the door body, the door accessories and the interior cover. The door body includes the inner and outer panels of the door, the door reinforcement beam, the door reinforcement plate, etc., the hinge, the door lock mechanism, the inner and outer handles, the glass and the glass regulator and the sealing strip, etc. constitute the accessories of the door, and the inte...

AI Technical Summary

Problems solved by technology

[0005] As mentioned above, the traditional existing car door structure is usually a steel plate structure, which has certain requirements in terms of stiffness, strength, and dent resistance. Usually, many reinforcement plates are designed, which have the disadvantages of heavy weight, complicated process operation, high cost, and modularization. The shortcoming of being low, and the long development and design cycle of the door, the large investment in molds and other conditions
