Technical Field

[0001] The present invention relates to the technical field of mobile cabin structures. More specifically, the present invention relates to a cabin panel structure and a cabin body. Background Art

[0002] The existing common cabin panel structure is generally composed of a metal skin and a metal skeleton, and polyurethane foam is filled in the skeleton. Resin is scraped on both sides of the metal skeleton and polyurethane foam structure, and then the metal skin is bonded on both sides. It is formed by hot pressing with a large plate press. Using the metal cabin panel forming and manufacturing method, the lightweight design of the mobile cabin cannot be effectively realized.

[0003] Some existing cabin panel structures use composite materials to meet the lightweight requirements. However, most composite materials have low strength. Generally, only the skin or some areas can use composite materials, and the large-scale use of composite materials cannot be realized, resulting in the inability to achieve better lightweight. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention innovatively provides a cabin panel structure and a cabin body, which can solve the problem that the composite material strength in the prior art is insufficient, resulting in the inability to realize the lightweight design of the cabin panel structure.

[0005] To achieve the above technical purpose, in the first aspect of the present invention, a cabin panel structure is disclosed, including a frame, a skin, and a filling block.

[0009] Further, the skin includes three layers of carbon fiber twill cloth.

[0010] Wherein, an included angle of 40° - 50° is formed between the twills of adjacent two layers of carbon fiber twill cloth.

[0012] Further, a resin bonding layer is provided between the three layers of carbon fiber twill cloth of the skin, and the resin bonding layer bonds adjacent two layers of carbon fiber twill cloth into one body.

[0013] Further, the wrapping layer is formed by stacking six layers of carbon fiber twill fabrics,

[0014] and an included angle of 40°-50° is formed between the twills of adjacent two layers of carbon fiber twill fabrics.

[0015] Further, the twill angle on adjacent two layers of the carbon fiber twill fabrics increases by 45°.

[0016] Further, an included angle of 40°-50° is formed between the twills of the two layers of carbon fiber twill fabrics connected to the skin and the framework.

[0017] Further, the filling block is made of polyurethane foam material, and a connecting layer is adhesively attached to the surface of the filling block, and the connecting layer is used for adhesively connecting with the skin and the framework.

[0028] The following will combine the accompanying drawings of the specification to give a detailed explanation and description of the cabin board structure and the cabin body provided by the present invention.

[0029] All parts of the cabin board structure provided by the present invention are made of carbon fiber composite materials, realizing a lightweight design. By optimizing the twill angles of each layer of carbon fiber twill cloth, an included angle is formed between the twills of adjacent carbon fiber twill cloths, thereby increasing the strength of the overall structure. After forming the cabin board structure, the cabin board has high strength in multiple directions, thus meeting the strength requirements of the shelter. The following will introduce the present invention in detail with specific embodiments:

[0030] In some embodiments, the present invention provides a cabin board structure, as Figure 1 shown, including a frame 1, a skin 2 and a filling block 3. A hollow structure is formed on the frame 1, the filling block 3 is filled into the hollow structure, and the skin 2 is arranged on both sides of the frame 1 and adhered to both sides of the frame 1 and the filling block 3 to form a cabin board structure.

[0031] The frame 1 is composed of a skeleton and a wrapping layer. The skeleton is formed by cutting a foam board with a machine tool, and the wrapping layer wraps the skeleton. Optionally, as Figure 2 shown, there are multiple support rods 11 in the skeleton separated into a hollow structure. The connection points of the support rods 11 usually form a cross-shaped or T-shaped structure, and stress concentration usually occurs at these connection points, which is likely to cause the connection points to be stressed and broken. Optionally, at the connection points, the two support rods 11 are fixed by the wrapping layer in a cross-winding manner, for example, wound in a connection manner similar to a two-way, three-way or four-way connection.

[0032] In some embodiments, as Figure 3 shown, both the wrapping layer and the skin 2 are made of carbon fiber twill cloth 4. The carbon fiber twill cloth 4 is evenly distributed with parallel twills on the surface, making the carbon fiber twill cloth 4 have the strongest load-bearing capacity in the extending direction of the twills.

[0033] Optionally, the wrapping layer is composed of multiple layers of carbon fiber twill cloth 4. Among the multiple layers of carbon fiber twill cloth 4 of the wrapping layer, optionally, the wrapping layer includes up to six layers of carbon fiber twill cloth 4. An included angle is formed between the twills of adjacent two layers of carbon fiber twill cloth 4, so that it can have a high load-bearing capacity in different directions. Optionally, an included angle of 40° - 50° is formed between the twills of adjacent two layers of carbon fiber twill cloth 4, for example, a 45° included angle is formed. The multiple layers of carbon fiber twill cloth 4 of the wrapping layer are formed in a way of being wound around the skeleton in a single pass, and a layer of resin glue is applied after each winding of a layer of carbon fiber twill cloth 4 to enable bonding and fixing with the next layer of carbon fiber twill cloth 4, and it can ensure that each layer of carbon fiber twill cloth 4 can be tightly wound without loosening, playing a role in strengthening the skeleton.

[0034] In some embodiments, the skin 2 is composed of multiple layers of carbon fiber twill cloth 4. Among the multiple layers of carbon fiber twill cloth 4 of the skin 2, an angle is formed between the twills on adjacent two layers of carbon fiber twill cloth 4. Since the skin 2 is not a main load-bearing member, its thickness should not be too large. Optionally, as Figure 4 shown, the skin 2 includes three layers of carbon fiber twill cloth 4. Among them, an angle of 40° - 50° is formed between the twills on adjacent two layers of carbon fiber twill cloth 4. For example, the angle is 45°. The setting of the three layers of carbon fiber twill cloth 4 enables the thickness of the skin 2 not to be too large, and can ensure its good load-bearing performance in multiple directions. Further, the twills on the outer two layers of carbon fiber twill cloth 4 of the skin 2 are perpendicular to each other. For example, the twill angle on adjacent two layers of carbon fiber twill cloth 4 increases by 45°, that is, when each layer of the skin 2 is laid, each layer of carbon fiber twill cloth 4 is inclined 45° in the same direction compared with the twill of the next lower layer, so that the plies of the skin 2 can cross, ensuring that the properties in all directions of the carbon fiber twill cloth 4 are complementary, making the skin 2 isotropic or nearly isotropic, and can improve the structural strength of the skin 2 in all directions.

[0035] Optionally, a resin bonding layer is provided between the three layers of carbon fiber twill cloth 4 of the skin 2. The resin bonding layer bonds adjacent two layers of carbon fiber twill cloth 4 into one body, and forms the skin 2 after resin bonding and curing. The skin 2 is formed separately from the frame 1, that is, the skin 2 is formed by overlapping three layers of carbon fiber twill cloth 4 and bonding and curing them with resin glue, and then bonding and forming with the framework through resin glue or other bonding adhesives.

[0036] In some embodiments, an angle of 40° - 50° is formed between the twills of the two layers of carbon fiber twill cloth 4 connected between the skin 2 and the framework, for example, the angle is 45°, so that the connection has good load-bearing capacity in different directions, and further improves the overall load-bearing capacity of the cabin panel structure.

[0037] In some embodiments, the filling block 3 is made of polyurethane foam material, and a connecting layer is pasted on the surface of the filling block 3. The connecting layer is used for bonding with the skin 2 and the framework. Optionally, the connecting layer includes at least one layer of carbon fiber twill cloth 4, and an angle of 40° - 50° is formed between the twills of the carbon fiber twill cloth 4 where the connecting layer is connected to the skin 2 and the framework, for example, the angle is 45°.

[0038] In some embodiments, the present invention also provides a cabin body, which includes a base, side plates and a top plate. Among them, at least the side plates and the top plate are composed of the above-mentioned cabin panel structure.

[0039] By optimizing the angles between the plies of the skin 2 and the wrapping layer of the frame 1 of the cabin panel structure, the present invention can optimize the anisotropic properties of the cabin panel structure into isotropic properties, so that the structural strength values in all directions of the composite material can reach the maximum, ensuring that the overall structural strength of the cabin panel structure is greatly improved, and thus improving the overall structural strength of the cabin body.
