[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-3 As shown in the figure, this utility model provides a multi-functional cargo gantry for automobiles, including two support frame structures, with a cargo platform 1 disposed between the two support frame structures. The cargo platform 1 has a plurality of grid holes and is used to carry at least automobile parts. An extension plate 5 is screwed to one side of the cargo platform 1, and a truss tube 16 is disposed on one side of the extension plate 5. The truss tube 16 is fixed to the extension plate 5 by bolts. A connecting plate 6 is screwed to one side of the support frame structure, and the cargo platform 1 is disposed above the connecting plate 6 and fixed by bolts.

[0021] In this specific embodiment, a loading platform 1 is provided between the two support frame structures. The loading platform 1 has several grid holes and is used to support at least automotive parts. An extension plate 5 is screwed to one side of the loading platform 1, and a truss tube 16 is provided on one side of the extension plate 5. The truss tube 16 is fixed to the extension plate 5 by bolts. A connecting plate 6 is screwed to one side of the support frame structure. The loading platform 1 is located above the connecting plate 6 and is fixed by bolts. A modular design is adopted, and the side plate 3, connecting plate 6, etc. are screwed together, which supports quick disassembly and assembly, facilitates transportation, storage, and partial replacement, and reduces maintenance costs. The extension plate and truss tube on one side of the loading platform are fixed by bolts, and accessories such as hooks and straps can be flexibly added to adapt to the fixing needs of goods of different sizes. The grid hole design has the functions of ventilation, weight reduction, and multi-directional fixing, preventing goods from sliding due to bumps.

[0022] Preferably, the support frame structure includes a vertical rod 4, one outer wall of which is welded to the truss tube 16; the welding of the vertical rod 4 to the truss tube 16 enhances the rigidity of the lateral support of the loading platform and prevents the extension plate 5 from deforming under stress.

[0023] Preferably, the support frame structure also includes a tie rod 2, and two horizontal bars 7 distributed from top to bottom are provided between the vertical rod 4 and the tie rod 2. The connecting plate 6 is bolted to the lower horizontal bar 7. The horizontal bars 7 distributed vertically between the vertical rod 4 and the tie rod 2 form a hierarchical structure of a trapezoidal frame, which improves the compressive strength. The connecting plate 6 is bolted to the lower horizontal bar 7 to ensure that the load of the loading platform 1 is evenly transferred to the support frame. Preferably, the support frame structure also includes a base rod 8, with both ends of the base rod 8 welded to the vertical rod 4 and the tie rod 2, respectively. The welding of the two ends of the base rod 8 to the vertical rod 4 and the tie rod 2 forms a closed bottom frame, further dispersing the load pressure and preventing the support frame structure from tilting due to uneven stress. The base rod 8 is also provided with threaded holes 10 for adding a second-layer loading platform.

[0024] Preferably, the bottom of the support frame structure is provided with two support legs 9, which are set on the bottom outer wall of the bottom rod 8 and welded to the bottom rod 8. The support legs 9 are welded to the bottom of the bottom rod 8 to increase the contact area with the vehicle, prevent the gantry from sliding during bumps, and avoid direct wear of the bottom rod 8.

[0025] Preferably, the support structure is trapezoidal in shape; the trapezoidal support structure transforms the vertical load into lateral support force through the mechanical properties of the inclined plane, reducing the risk of frame deformation.

[0026] Preferably, a side plate 3 is provided on one side of the support structure, and the side plate 3 is bolted to the crossbar 7. The bolted connection of the side plate 3 to the crossbar 7 not only enhances the lateral stability of the support frame, but also facilitates disassembly to adjust the layout of the loading space.

[0027] Example 1 A multi-functional cargo gantry for automobiles includes a cargo platform 1 positioned between two support frame structures. The cargo platform 1 has several grid holes and is used to support at least automobile parts. An extension plate 5 is screwed to one side of the cargo platform 1, and a truss tube 16 is installed on one side of the extension plate 5. The truss tube 16 is fixed to the extension plate 5 with bolts. A connecting plate 6 is screwed to one side of the support frame structure. The cargo platform 1 is positioned above the connecting plate 6 and fixed with bolts. The modular design allows for quick assembly and disassembly of the side plates 3 and connecting plates 6, facilitating transportation, storage, and partial replacement, thus reducing maintenance costs. The extension plate and truss tube on one side of the cargo platform (fixed with bolts) can be flexibly fitted with hooks, straps, and other accessories to accommodate the fixing needs of goods of different sizes. The grid hole design provides ventilation, weight reduction, and multi-directional fixing functions, preventing goods from sliding due to bumps.

[0028] Example 2 This embodiment further defines the support frame structure based on embodiment 1. The support frame structure includes vertical rods 4, one outer wall of which is welded to truss tubes 16. Welding the vertical rods 4 to truss tubes 16 enhances the rigidity of the lateral support of the loading platform and prevents deformation of the extension plate 5 under stress. The support frame structure also includes tie rods 2, with two horizontal bars 7 arranged from top to bottom between the vertical rods 4 and tie rods 2. A connecting plate 6 is bolted to the lower horizontal bar 7. The horizontal bars 7 arranged vertically between the vertical rods 4 and tie rods 2 form a trapezoidal frame hierarchical structure, improving compressive strength. The connecting plate 6 is bolted to the lower horizontal bar 7 to ensure that the load of the loading platform 1 is evenly transferred to the support frame. The support frame structure also includes a bottom rod 8, with both ends of the bottom rod 8 welded to the vertical rods 4 and tie rods 2 respectively. The bottom rod 8 is connected to the vertical rods 4 and tie rods 2 at both ends. Rod 4 and tie rod 2 are welded together to form a closed bottom frame, further dispersing the load pressure and preventing the support frame structure from tilting due to uneven stress. Two support legs 9 are provided at the bottom of the support frame structure. The support legs 9 are set on the bottom outer wall of the bottom rod 8 and are welded to the bottom rod 8. The support legs 9 are welded to the bottom of the bottom rod 8 to increase the contact area with the vehicle, prevent the gantry frame from sliding during bumps, and avoid direct wear of the bottom rod 8. The support structure is trapezoidal in shape. The trapezoidal support structure converts the vertical load into lateral support force through the mechanical properties of the inclined plane, reducing the risk of frame deformation. A side plate 3 is provided on one side of the support structure. The side plate 3 is bolted to the cross rod 7. The side plate 3 is bolted to the cross rod 7, which not only enhances the lateral stability of the support frame, but also facilitates disassembly to adjust the cargo space layout.
