Description

Technical Field

[0001] This utility model relates to the field of thermal insulation technology for mobile cabins, and in particular to a lightweight carbon fiber composite large panel. Background Technology

[0002] Containerized modular units (CMUs) were originally developed to meet the needs of battlefield operations. Due to their excellent battlefield mobility, rapid response capabilities, suitable working environment for equipment and personnel, and certain battlefield protection performance, they are widely used by the militaries of various countries. In recent years, with the increasing demand for CMUs across various industries, they have also been widely applied in civilian fields such as medical care, firefighting, meteorology, emergency communications, and command. Currently, traditional CMUs mainly adopt a structure assembled from large metal panels, which suffers from problems such as excessive weight, easy corrosion of the metal skin, and poor insulation. These issues cannot meet the requirements of the next generation of CMUs for lightweight design, multi-modal transport by sea, land, and air, and use in all environments. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Reference Figures 1 to 2 A lightweight carbon fiber composite panel includes two frames 10, an outer skin 2, an inner skin 3, and a heat insulation component. The heat insulation component includes several partitions 4 and an air venting component. The outer skin 2 and the inner skin 3 are both made of carbon fiber composite material. The air venting component connects the frame 10 and the several partitions 4. The outer skin 2 is located at the top of the frame 10 and one of the partitions 4, and the inner skin 3 is located at the bottom of one of the partitions 4. In this invention, two frames 10 are connected by an air outlet assembly, and each partition 4 is spaced apart. After the external air extraction device is connected to the air outlet assembly, it extracts air from the spacer 4, forming a vacuum and achieving better heat insulation. The outer skin 2 and the inner skin 3 are both made of carbon fiber composite material, which has advantages such as light weight, high strength, and strong corrosion resistance compared with traditional metal materials. It can not only improve the load-bearing ratio of the large plate, but also greatly improve the applicability of the large plate in harsh environments. In terms of weight reduction, under the same load, the carbon fiber composite large plate is more than 30% lighter than the traditional metal skin. The spaced partitions 4 reduce the overall weight of the large plate. At the same time, the frame 10 can be made of aluminum to further reduce the weight of the large plate.

[0016] As a preferred embodiment of this utility model, it may also have the following additional technical features:

[0017] In this embodiment, the skeleton 10 includes an outer frame 101 and a plurality of reinforcing ribs 102. The reinforcing ribs 102 are disposed within the outer frame 101 to improve the stability of the outer frame 101.

[0018] In this embodiment, the outer frame 101 is provided with a pre-embedded plate 1011. The pre-embedded plate 1011 is used to fix related facilities and equipment such as fixed components on the large panel of the container, so as to facilitate the fixing of equipment.

[0019] In this embodiment, the air outlet assembly includes a horizontal pipe 5 and a vertical pipe 6. The horizontal pipe 5 connects the frame 10 and the vertical pipe 6, and the vertical pipe 6 connects to several partitions 4. The vertical pipe 6 has several air holes 601, and the horizontal pipe 5 has a valve. An external air extraction device works by extracting air between the partitions 4 through the air holes 601 on the horizontal pipe 5 and the vertical pipe 6, thus improving the heat insulation effect of the partitions 4. Specifically, the vertical pipe 6 is fixedly connected to the partitions 4.

[0020] In this embodiment, the horizontal tube 5 is provided with threads; the air outlet assembly also includes a nut 7, which is screwed to the horizontal tube 5. One end of the horizontal tube 5 passes through one side of the frame 10 and is screwed to the nut 7, which facilitates installation and disassembly.

[0021] In this embodiment, two thermal insulation bridges 8 are also included, which are respectively disposed at the bottom of the frame 10, thereby improving the thermal insulation performance of the large panel.
