Integral structure of automotive plastic back door

Abstract

The technical field of auto parts of the present invention relates in particular to a highly integrated and modularized automotive plastic back door integrated structure, which includes an outer panel, an inner panel and a back door trim connected sequentially from outside to inside; the invention sets the car back door There are three modular structures for the inner panel, outer panel and back door trim. The inner panel and the outer panel highly integrate the existing functional parts and assembly structures. During assembly, only the inner panel and outer panel need to be assembled. Assemble the panel and the back door trim, and then install each assembly on the corresponding assembly installation structure, thus realizing the modular overall assembly of the car back panel, greatly reducing the assembly process of the back door assembly, and improving the assembly efficiency and assembly quality; at the same time, the inner panel and the outer panel realize the integration of the assembly structure of each assembly, which facilitates the installation of each assembly on the back door and reduces the assembly and manufacturing cost of the back door.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a highly integrated and modularized automotive plastic back door integrated structure. Background technique [0002] With the development of the global automobile industry and the increase in car ownership, environmental pollution is becoming more and more serious. Energy conservation and environmental protection have become the most important research and development topics in the automotive industry. At present, one solution is energy-saving and new energy vehicle technology, and the other is vehicle lightweight technology. The car back door is an important part of the car. Using non-metallic materials to replace the traditional metal sheet metal door panels, the design has obvious weight reduction effect and can achieve the purpose of weight reduction. [0003] Existing automobile back doors are usually composed of sheet metal parts, and the sheet metal back door is compos...

AI Technical Summary

Problems solved by technology

[0003] Existing automobile back doors are usually composed of sheet metal parts, and the sheet metal back door is composed of back door welding assembly, back door hinge assembly, handle box assembly, back door interior trim assembly, back door exterior trim assembly , rear windshield, spoiler assembly, camera assembly, high-mount brake light assembly, rear window wiper motor assembly, lock mechanism, rear door wire harness assembly, license plate light wire harness assembly, tail decoration Light assembly, license plate light assembly, back door brace, etc. The car back door needs to be assembled one by one on the welding line or final assembly line. The production process is long, the process is scattered, and the quality of each process It is not easy to detect and control, which increases the difficulty of assembly and management, and the manufacturing cost of the car back door, and it is difficult to guarantee the overall quality of the back door
