[0030] like Figures 1 to 6 As shown, a mobile home skeleton structure includes a chassis assembly 3, a roof assembly 4, a column assembly 2, and support legs 30. The chassis assembly 3 is located below the roof assembly 4, with the column assembly 2 disposed between the chassis assembly 3 and the roof assembly 4. The support legs 30 are vertically disposed on the lower surface of the chassis assembly 3.

[0031] The pillar assembly 2 includes a front door assembly 5, a rear door assembly 6, a pillar 10, and a window assembly.

[0032] The front door assembly 5 is provided at one end in the longitudinal direction of the chassis assembly 3 and the roof assembly 4, with its bottom connected to the chassis assembly 3 and its top connected to the roof assembly 4. The rear door assembly 6 is provided at the other end in the longitudinal direction of the chassis assembly 3 and the roof assembly 4, with its bottom connected to the chassis assembly 3 and its top connected to the roof assembly 4.

[0033] The window assembly is disposed at one end in the transverse direction between the chassis assembly 3 and the ceiling assembly 4, with its bottom connected to the chassis assembly 3 and its top connected to the ceiling assembly 4. The pillar 10 is disposed at the other end in the transverse direction between the chassis assembly 3 and the ceiling assembly 4, with its bottom connected to the chassis assembly 3 and its top connected to the ceiling assembly 4.

[0034] The columns 10 are provided in at least four groups and are evenly arranged in the longitudinal direction. The spacing between two adjacent columns 10 is 300mm-2000mm. The columns 10 are square tube structures with a cross-section width of 1200mm, a height of 120mm, and a wall thickness of 4mm.

[0035] The window assembly includes an upper window crossbeam 7, a lower window crossbeam 8, and window side support columns 9. The window side support columns 9 are vertically arranged on the chassis assembly 3, and their upper ends are connected to the ceiling assembly 4. The window side support columns 9 are used for glass installation and for supporting the ceiling assembly 4 and bearing the weight of the ceiling assembly 4. Their functions are the same as those of the columns 10. The upper window crossbeam 7 is connected between the upper end of the window side support column 9 and the rear door assembly 6, and the lower window crossbeam 8 is connected between the lower end of the window side support column 9 and the rear door assembly 6.

At the same time, the upper window crossbeam 7 is connected to the ceiling assembly 4, and the lower window crossbeam 8 is connected to the chassis assembly 3. The window side support columns 9 can be adjusted according to the size of the window.

[0036] Through the above-mentioned arrangement, the stability of the overall structure of the house is ensured while the number of columns 10 is reduced. The ceiling assembly 4 and the chassis assembly 3 are located at one end of the window assembly and the support effect is achieved only by a group of window-side support columns 9. This can realize the design of large viewing windows, improve the lighting of the house, and enhance the user's living experience.

[0037] As a supplement to the technical solution of the present invention, since only one window side support column 9 is provided at the position of the window assembly, in order to ensure the overall structural strength of the reinforced keel, a window side reinforcement ring 1 is also included. The window side reinforcement ring 1 is provided at one end in the transverse direction of the chassis assembly 3 and the ceiling assembly 4, and is located on the outside of the window assembly. It includes a first annular reinforcement ring 11 and a first annular reinforcement ring column 12. The upper portion of the first annular reinforcement ring 11 is connected to the ceiling assembly 4, the lower portion is connected to the chassis assembly 3, the front portion is connected to the front door assembly 5, and the rear portion is connected to the rear door assembly 6. The first annular reinforcement ring column 12 is vertically provided on the first annular reinforcement ring 11, with its upper end connected to the upper portion of the first annular reinforcement ring 11 and its lower end connected to the lower portion of the first annular reinforcement ring 11. The first annular reinforcement ring column 12 is arranged opposite to the window side support column 9, which can avoid the technical problem of the first annular reinforcement ring column 12 blocking sunlight. Since the window side assembly lacks the column 10, the window side reinforcement ring 1 is provided to share the load of the ceiling assembly 4, and the first annular reinforcement ring column 12 is provided to further enhance the bearing capacity of the window side reinforcement ring 1.

[0038] As a supplement to the above technical solution, the outer periphery of the window side reinforcement ring 1 is uniformly arrayed with square tubes, which connect to the ceiling assembly 4, chassis assembly 3, front door assembly 5, and rear door assembly 6. The square tubes on both sides of the window side reinforcement ring 1 in the longitudinal direction are straight square tubes, while the square tubes on both sides of the window side reinforcement ring 1 in the vertical direction are oblique square tubes, which can serve as reinforcement ribs between the window side reinforcement ring 1 and the ceiling assembly 4.

[0039] As a preferred technical solution of the present invention, a door-side reinforcement ring 13 is further included. It is arranged at one end of the chassis assembly 3 and the roof assembly 4 in the transverse direction, away from the window-side reinforcement ring 1. It includes a second annular reinforcement ring 14 and a second annular reinforcement ring column 15. The upper portion of the second annular reinforcement ring 14 is connected to the roof assembly 4, the lower portion is connected to the chassis assembly 3, the front portion is connected to the front door assembly 5, and the rear portion is connected to the rear door assembly 6. The second reinforcement ring column 10 is vertically arranged on the second annular reinforcement ring 14, with its upper end connected to the upper portion of the second annular reinforcement ring 14 and its lower end connected to the lower portion of the second annular reinforcement ring 14. The provision of the second annular reinforcement ring 14 shares the load of the roof assembly 4, and the provision of the second reinforcement ring column 10 further enhances the bearing capacity of the door-side reinforcement ring 13. The second annular reinforcement ring columns 15 are provided in at least four groups. One group of second annular reinforcement ring columns 15 is positioned opposite the first annular reinforcement ring columns 12. The second annular reinforcement ring columns 15 positioned opposite the first annular reinforcement ring 11 are square tube structures with a cross-sectional width of 100 mm, a height of 50 mm, and a wall thickness of 4 mm. The remaining second annular reinforcement ring columns 15 are 50 mm wide, 50 mm high, and 4 mm thick. Furthermore, the second annular reinforcement ring columns 15 are positioned opposite each group of columns 10 in the column assembly, reducing light obstruction and improving daylighting.

[0040] As a supplement to the above technical solution, the door-side reinforcement ring 13 is evenly arrayed with square tubes around its periphery, connecting it to the roof assembly 4, chassis assembly 3, front door assembly 5, and rear door assembly 6. The square tubes on either side of the door-side reinforcement ring 13 in the longitudinal direction are straight, while the square tubes on either side of the door-side reinforcement ring 13 in the vertical direction are oblique square tubes, which serve as reinforcement ribs between the door-side reinforcement ring 13 and the roof assembly 4.
