Technical Field

[0001] The invention relates to a vehicle-mounted cabin structure, in particular to a special-shaped cabin structure with light weight and high strength, belonging to the technical field of vehicle-mounted cabins. Background Art

[0002] The vehicle-mounted cabin is a box-type equipment installed on a vehicle platform for field operations such as geological exploration, water conservancy projects, construction projects, emergency rescue, and communication command. In order to meet the needs of vehicles carrying cabins passing through road or railway tunnels, the protective cabin adopts a polyhedral special-shaped structure and is often used to shield and protect some equipment installed on the vehicle platform.

[0003] At present, the protective cabin panels are mostly made of two layers of aluminum panels inside and outside, with a light steel profile skeleton structure filled with a foam material layer in the middle, which ensures the overall strength of the protective cabin and meets the needs of personnel climbing to the top. The disadvantage is that the overall mass is large, which affects the maneuverability of the vehicle. There are also protective cabins made of carbon fiber materials. The protective cabin panels are made of two layers of carbon fiber plates inside and outside, with a carbon fiber tube skeleton in the middle that is fixed with glue rivets and also sandwiched with a foam material layer. The appearance consistency of the protective cabin with this structure is poor, and there are many rivets. The rivet holes reduce the mechanical properties of the carbon fiber material, which seriously affects the strength and stiffness of the protective cabin. Summary of the invention

[0025] Figure 1 and Figure 2The right side of the carbon fiber special-shaped protective cabin shown is an inclined facade 3, and a shutter 4 is provided at the right end of the inclined facade 3. A bottom rod 31 is provided at the bottom of the inclined facade 3. The bottom rod 31 is a special-shaped cross-section carbon fiber tube whose shape matches the lower side of the inclined facade 3. The lower ends of the three vertical rods 32 arranged at intervals are respectively connected to the bottom rod 31 vertically by gluing, and the upper ends are respectively connected to the right side of the composite top plate 1 vertically by gluing. The vertical rod 32 is a rectangular cross-section carbon fiber tube. The vertical connection between the vertical rod 32 and the bottom rod 31 is fixed by gluing and riveting on both sides, the lower side of the composite end panel 2 and the side of the adjacent bottom rod 31, respectively, to improve the structural strength and rigidity of the present invention, and improve the stability of the overall structure.
