[0039] A cabin frame structure comprises a rod group and a connecting assembly. The rod group is connected through the connecting assembly to form a frame structure. The connecting nodes are stable and reliable and easy to assemble.

[0040] See also Figure 1 The rod group of this embodiment includes a plurality of longitudinal beams 11, a plurality of transverse beams 12 and a plurality of columns 13. The longitudinal beams 11, the transverse beams 12 and the columns 13 are all made of profiles. Specifically, the profiles are pultruded. Please refer to Figure 2 The tube wall 101 of the profile is made of fiber-reinforced materials, such as carbon fiber, basalt fiber, or glass fiber, and the inside of the tube wall 101 is filled with foaming material 102, such as foaming polyurethane, foaming polymethacrylimide, foaming epoxy resin and other low-density materials.

[0041] This embodiment uses the above-mentioned material settings to give the profile the characteristics of high strength, high rigidity, light weight, corrosion resistance and low thermal conductivity.

[0042] In this embodiment, the longitudinal beam 11 is arranged along the first direction, the cross beam 12 is arranged along the second direction, and the column 13 is arranged along the third direction. The first direction, the second direction and the third direction are perpendicular to each other. The longitudinal beam 11 and the cross beam 12 cooperate to form a two-layer planar structure, and the column 13 is arranged between the two-layer planar structure, so that four of the columns 13 are respectively cooperated with the end of a cross beam 12 and the end of a longitudinal beam 11 to form eight angular nodes. The eight angular nodes are eight vertical angles of the overall structure, and the remaining columns 13 are respectively cooperated with the ends of two cross beams 12 and the end of a longitudinal beam 11 to form a number of double T-shaped nodes.

[0043] For further information, see Figure 1The connection assembly of this embodiment includes an angle connector 21 and a double T-shaped connector 22. The angle connector 21 corresponds to the angle node one by one. The angle connector 21 is configured to connect a column 13, a cross beam 12 and a longitudinal beam 11 to form the angle node. The double T-shaped connector 22 corresponds to the double T node one by one. The double T-shaped connector 22 is configured to connect a column 13, two cross beams 12 and a longitudinal beam 11 to form the double T node. Preferably, the angle connector 21 and the double T-shaped connector 22 are made of metal materials.

[0044] In this embodiment, the longitudinal beams 11, the cross beams 12 and the columns 13 are assembled by the corner connectors 21 and the double T-shaped connectors 22 to form a frame structure. The assembly is simple and efficient, and drilling holes on the longitudinal beams 11, the cross beams 12 and the columns 13 is avoided, thereby ensuring the stability of the connection nodes.

[0045] Specifically, in this embodiment, the longitudinal beam 11 is arranged along the first direction, the cross beam 12 is arranged along the second direction, the first direction is perpendicular to the second direction, and the longitudinal beam 11 and the cross beam 12 cooperate to form a two-layer planar structure, the column 13 is arranged between the two-layer planar structure along the third direction, and the first direction, the second direction and the third direction are perpendicular to each other. Preferably, a plurality of longitudinal beams 11 located in the same layer of the planar structure are evenly spaced along the second direction, and two cross beams 12 are arranged between two adjacent longitudinal beams 11, that is, two cross beams 12 are arranged between the two ends of one longitudinal beam 11 and the two ends of the other longitudinal beam 11 of the two adjacent longitudinal beams 11.

[0046] The longitudinal beams 11, transverse beams 12 and columns 13 of this embodiment are made of a fiber composite material with an internally filled foam material 102, and are further fixed by corner connectors 21 and double T-shaped connectors 22 to form a frame of the cabin, and have the characteristics of light weight, high strength, corrosion resistance, easy assembly, and stable and reliable connection nodes.

[0047] See also Figure 3 The corner connector 21 includes a first rectangular tube 211 and two first C-shaped members 212. One end of the first rectangular tube 211 is blocked, and one end of the two first C-shaped members 212 is circumferentially welded to two adjacent side walls of the first rectangular tube 211. A C-shaped groove is formed inside the first C-shaped member 212 to accommodate the crossbeam 12 or the longitudinal beam 11. The frame is initially fixed. One groove wall of the two first C-shaped members 212 is flush with the blocked end of the first rectangular tube 211 to ensure that the longitudinal beam 11 and the crossbeam 12 located on the same plane structure can be respectively accommodated in the C-shaped grooves of the two first C-shaped members 212.

[0048] Preferably, during the assembly process, one end of the column 13 forming the angle node extends into the first rectangular tube 211 and abuts against the blocked end, and the cross beam 12 and the longitudinal beam 11 forming the corresponding angle node extend into the C-shaped grooves of the two first C-shaped members 212 respectively to complete the preliminary fixation. Further preferably, the surface of the C-shaped groove of the first C-shaped member 212 is roughened, such as knurling, to increase the surface roughness, improve the friction coefficient with the longitudinal beam 11 or the cross beam 12, and improve the stability of the connection node.

[0049] Furthermore, a hydraulic device is used to extrude the first rectangular tube 211 and the first C-shaped member 212, so that partial areas of the two groove walls of the first C-shaped member 212 and partial areas of the first rectangular tube 211 are recessed inward and embedded in the longitudinal beam 11, the transverse beam 12 and the column 13, and the longitudinal beam 11, the transverse beam 12 and the column 13 produce elastic deformation, thereby improving the connection strength between the corner connector 21 and the longitudinal beam 11, the transverse beam 12 and the column 13 forming the corner node, thereby improving the stability of the connection node.

[0050] In order to further improve the connection strength between the corner connector 21 and the longitudinal beam 11, the transverse beam 12 and the column 13 forming the angled node, and to prevent the longitudinal beam 11 or the transverse beam 12 from detaching from the corner connector 21, in this embodiment, the inner wall of the groove bottom of one of the first C-shaped members 212 in the corner connector 21 is arranged to face the outer wall of the groove bottom of the other first C-shaped member 212. After accommodating the longitudinal beam 11 or the transverse beam 12, the two ports of one of the first C-shaped members 212 of the corner connector 21 face outwards. In this embodiment, a first connecting plate is provided to connect the two outward ports of the first C-shaped member 212, that is, the first connecting plate is connected between the two groove walls of the first C-shaped member 212 facing away from the groove bottom, so as to prevent the longitudinal beam 11 or the transverse beam 12 from detaching through the notch of the first C-shaped member 212. Preferably, the first connecting plate is welded to the first C-shaped member 212, and is made of metal material, so as to have a high connection strength.

[0051] See also Figure 4 The double T-shaped connecting member 22 includes a second rectangular tube 221 and two second C-shaped members 222. The axis of the second rectangular tube 221 is perpendicular to the axis of the two second C-shaped members 222. Both ends of the second rectangular tube 221 are open. The two cross beams 12 forming the double T-shaped node extend into the second rectangular tube 221 from the openings at both ends of the second rectangular tube 221 respectively. One ends of the two second C-shaped members 222 are circumferentially welded to the two adjacent side walls of the second rectangular tube 221 respectively. A C-shaped groove is formed inside the second C-shaped member 222 to accommodate the longitudinal beam 11 or column 13 forming the corresponding double T-shaped node, thereby preliminarily fixing the frame.

[0052] In this embodiment, the groove bottoms of two second C-shaped members 222 are parallel and oriented in the same direction. In other feasible embodiments, the groove bottoms of the second C-shaped members 222 may be oriented in other directions as long as they can respectively and simultaneously accommodate the longitudinal beams 11 and columns 13 forming corresponding double T-shaped nodes, and no specific limitation is made here.

[0053] Preferably, during the assembly process, the two crossbeams 12 forming the double T-shaped node are respectively extended from the two ends of the second rectangular tube 221, and the columns 13 and the longitudinal beams 11 forming the corresponding double T-shaped nodes are respectively extended into the C-shaped grooves of the two second C-shaped members 222 to complete the preliminary fixation. Further preferably, the surface of the C-shaped groove of the second C-shaped member 222 is roughened, such as knurling, to increase the surface roughness, improve the friction coefficient with the longitudinal beam 11 or the column 13, and improve the stability of the connection node.

[0054] Furthermore, a hydraulic device is used to extrude the second rectangular tube 221 and the second C-shaped member 222, so that partial areas of the two groove walls of the second C-shaped member 222 and partial areas of the second rectangular tube 221 are recessed inward and embedded in the longitudinal beam 11, the column 13 and the cross beam 12, and the longitudinal beam 11, the column 13 and the cross beam 12 produce elastic deformation, thereby improving the connection strength between the double T-shaped connecting member 22 and the longitudinal beam 11, the column 13 and the cross beam 12 forming the double T-shaped node, thereby improving the stability of the connection node.

[0055] In order to further improve the connection strength between the double T-shaped connector 22 and the longitudinal beam 11, the cross beam 12 and the column 13 forming the double T-shaped node, and to prevent the longitudinal beam 11 or the cross beam 12 from being separated from the double T-shaped connector 22, the present embodiment is provided with a second connection plate, each double T-shaped connector 22 is connected to at least one second connection plate, and the second connection plate is connected to the notch of the second C-shaped member 222, that is, the first connection plate is connected between the two groove walls of the second C-shaped member 222 away from the groove bottom, so as to prevent the longitudinal beam 11 or the cross beam 12 from being separated through the notch of the second C-shaped member 222. Preferably, the second connection plate is welded to the second C-shaped member 222, and is made of metal material, so as to have a high connection strength.

[0056] Optionally, a cabin frame structure provided in this embodiment is provided with at least four lifting points, and the four lifting points are connected to form a rectangle. Specifically, fixing bolts are prefabricated on the double T-shaped connector 22, and the fixing bolts form the lifting points. Through the above arrangement, during the lifting process of the cabin frame structure, the lifting hanger is connected to the fixing bolts, the stress distribution is uniform, and the frame structure is less deformed.

[0057] In order to further improve the lightweight of a cabin frame structure, the cabin frame structure provided in this embodiment removes two columns 13 in the middle area while ensuring the stability of the overall structure. The original double T-shaped node forms a T-shaped node after the columns 13 are removed.

[0058] Specifically, in the area where the support of the columns 13 is removed, at one layer of the plane structure, two ends of a longitudinal beam 11 form two T-shaped nodes with the adjacent cross beams 12 on both sides thereof, and two T-shaped nodes are also formed at the corresponding positions of another layer of the plane structure.

[0059] Suitably, the connection assembly further includes a T-shaped connector 23, which corresponds to the T-shaped node one by one, and is configured to connect two cross beams 12 and one longitudinal beam 11 forming the T-shaped node, and the connection is firm, which further optimizes the lightweight structure, and avoids drilling holes on the longitudinal beam 11 and the cross beam 12, thereby ensuring the stability of the connection node. Preferably, the T-shaped connector 23 is made of metal material.

[0060] See also Figure 5 The T-shaped connecting member 23 includes two third C-shaped members 231, one end of one of the third C-shaped members 231 is circumferentially welded to the middle area of ​​the outer wall of the groove bottom of the other third C-shaped member 231, and the two cross beams 12 forming the T-shaped node extend into the C-shaped groove of one of the third C-shaped members 231 relatively, and the longitudinal beam 11 forming the corresponding T-shaped node extends into the C-shaped groove of the other third C-shaped member 231, thereby preliminarily fixing the frame.

[0061] The groove bottom of the third C-shaped member 231 may be oriented in other directions as long as it can simultaneously accommodate the longitudinal beam 11 and the transverse beam 12 forming the corresponding T-shaped node, and no specific limitation is made here.

[0062] Preferably, during the assembly process, the two crossbeams 12 forming the T-shaped node extend relatively into the C-shaped groove of one of the third C-shaped members 231, and the longitudinal beam 11 forming the corresponding T-shaped node extends into the C-shaped groove of the other third C-shaped member 231 to complete the preliminary fixation. Further preferably, the surface of the C-shaped groove of the third C-shaped member 231 is roughened, such as knurling, to increase the surface roughness, improve the friction coefficient with the longitudinal beam 11 or the column 13, and improve the stability of the connection node.

[0063] Furthermore, a hydraulic device is used to extrude the third C-shaped member 231 so that partial areas of the two groove walls of the third C-shaped member 231 are recessed inward and embedded in the longitudinal beam 11 and the transverse beam 12, and the longitudinal beam 11 and the transverse beam 12 produce elastic deformation, thereby improving the connection strength between the T-shaped connector 23 and the longitudinal beam 11 and the transverse beam 12 forming the T-shaped node, thereby improving the stability of the connection node.

[0064] In order to further improve the connection strength between the T-shaped connector 23 and the longitudinal beam 11 and the transverse beam 12 forming a T-shaped node, and to prevent the longitudinal beam 11 or the transverse beam 12 from being separated from the T-shaped connector 23, the present embodiment is provided with a third connecting plate, specifically, the third connecting plate is connected to the notch of the third C-shaped member 231, that is, the third connecting plate is connected between the two groove walls of the third C-shaped member 231 on the side away from the groove bottom. Preferably, the third connecting plate is welded to the third C-shaped member 231, and a metal material is selected.
