[0032] This embodiment provides a special-purpose vehicle and a spare tire rack for the special-purpose vehicle.

[0033] A special vehicle includes a vehicle frame and a plurality of special vehicle spare tire racks. The special vehicle spare tire racks are detachably mounted on the bottom of the vehicle frame. The plurality of special vehicle spare tire racks are arranged in parallel.

[0034] See Figure 1 and Figure 2 The dedicated vehicle spare tire rack 10 of this embodiment is used to store a spare tire 20. The dedicated vehicle spare tire rack 10 includes a first connecting beam 11, a second connecting beam 12, and a fastening structure 13. Specifically, in this embodiment, the first connecting beam 11 is disposed on the vehicle frame in a direction perpendicular to the vehicle's straight-ahead travel direction, representing a transverse arrangement. The second connecting beam 12 is disposed on the vehicle frame in a direction parallel to the vehicle's straight-ahead travel direction, representing a longitudinal arrangement.

[0035] One end of the first connecting beam 11 is bent into a step-like shape to form a first support portion 111, and the other end is provided with a first connecting member 112 for engaging with the vehicle frame. An inclined portion 115 is provided between the first supporting portion 111 and the end of the first connecting beam 11 provided with the first connecting member 112. Figure 3 The angle between the first support portion 111 and the inclined portion 115 is an obtuse angle. The size of the spare tire 20 placed on the first support portion 111 can be slightly larger or smaller, and the side surfaces of the spare tire can abut against the inclined portion 115 to ensure stable fixation of the spare tire 20.

[0036] The middle portion of the second connecting beam 12 is bent into a concave shape to form a second supporting portion 121. The second connecting beam 12 is detachably connected to the first connecting beam 11.

[0037] Specifically, the first connecting beam 11 has a first support portion 111, and a connecting plate 110 is provided at one end thereof. The connecting plate 110 is arranged parallel to the second connecting beam 12. Screw holes are provided in the connecting plate 110 of the first connecting beam 11. A plurality of screws are provided through the second support portion 121 of the second connecting beam 12, and the connecting plate 110 is fastened to the second support portion 121 of the second connecting beam 12 via the screws.

[0038] It can be understood that the first connecting beam 11 and the second connecting beam 12 can also be detachably connected by means of buckles, latches, bolts, etc.

[0039] Both ends of the second connecting beam 12 are equipped with second connecting members 122 for engaging with the vehicle frame. The first and second supporting portions 111, 121 are connected to form a storage space for the spare tire. Specifically, in this embodiment, the first and second supporting portions 111, 121 are arranged perpendicularly, allowing them to symmetrically withstand the pressure from the spare tire. This ensures that the spare tire is subjected to balanced forces within the storage space and remains stably placed on the dedicated spare tire rack.

[0040] The first connector 112 and the second connector 122 are positioned near the vehicle frame relative to the storage space. The first connector 112 and the two second connectors 122 form three connection points with the vehicle frame, ensuring the dedicated spare tire rack maintains a stable connection to the vehicle frame. Furthermore, both the first connector 112 and the second connector 122 engage the vehicle frame, facilitating installation and removal.

[0041] The first connecting member 112 is provided at one end of the first connecting beam 11. Furthermore, the first connecting beam 11 has a first connecting portion 113 near the first connecting member 112 for mounting the first connecting member 112. Similarly, the second connecting beam 12 is bent at both ends where the second connecting members 122 are provided, forming second connecting portions 123 for mounting the second connecting members 122. The first connecting portion 113 and the two second connecting portions 123 are parallel to each other and lie in the same plane. The three connecting portions ensure that the three connecting members remain stably fixed to the bottom of the frame, maintaining uniform force.

[0042] Specifically, in this embodiment, both the first connector 112 and the second connector 122 include a clamping block 141 and a fastening post 142. The clamping block 141 is configured to engage with the wing panel of the vehicle frame, while the fastening post 142 compresses the clamping block 141 and the wing panel. The clamping block 141 is directly mounted on the wing panel of the vehicle frame. The clamping block 141 is fixed to the fastening post 142. Adjusting the position of the fastening post 142 adjusts the position of the clamping block 141 relative to the wing panel.

[0043] The fastening column 142 is a fastening bolt. The fastening bolt is threadedly connected to the first connecting beam 11. By selecting and installing the fastening bolt, the compression state between the clamping block 141 and the wing plate can be adjusted.

[0044] The clamping blocks 141 of the first and second connectors 112, 122 are capable of retaining various types of vehicle frame wing panels. Furthermore, the fastening posts 142 are also independent of the type of frame wing panel. Therefore, the dedicated spare tire rack of this embodiment can be adapted to various vehicle frames with varying beam spacings, demonstrating its wide versatility.

[0045] In other embodiments, the first connecting member 112 and the second connecting member 122 may also be buckles, claws, etc., to achieve the snap connection between the first connecting beam 11 and the second connecting beam 12 and the vehicle frame. Therefore, the above-mentioned dedicated vehicle spare tire rack is mounted on the vehicle frame through the buckle, without the need for pre-drilling holes in the vehicle frame, and is easy to install and use.

[0046] The first connecting beam 11 has a reinforcing plate 114 at one end thereof where the first connecting member 112 is provided. The reinforcing plate 114 is arranged along the axial direction of the first connecting beam 11. The reinforcing plate 114 enhances the strength of the end thereof where the first connecting member 112 is provided, thereby ensuring safe use of the special vehicle spare tire rack.

[0047] To enhance the stability of the spare tire rack, screw holes are provided on one side of the first connecting beam 11 and the first connecting member 112. Screw holes are also provided on one side of the second connecting beam 12 and the two second connecting members 122. Bolts are used to reinforce the first and second connecting beams 11, 12 to the vehicle frame, maintaining a secure connection between the spare tire rack and the vehicle frame.

[0048] The fastening structure 13 is detachably connected to the first support portion 111. The fastening structure 13 includes a column 131 and a pressing portion 132 provided at one end of the column 131. The other end of the column 131 is provided on the first support portion 111. The pressing portion 132 moves closer to or further away from the first support portion 111 to press or release the spare tire.

[0049] Specifically, in this embodiment, the column 131 is a stud, and the pressing portion 132 is threadedly connected to the column 131 . The pressing portion 132 is rotated to adjust its position on the column 131 .

[0050] Please also see Figure 2 Specifically, the clamping portion 132 is long and narrow. A column 131 extends through the middle of the clamping portion 132. Hooks 134 are provided at each end of the clamping portion 132. Hooks 134 are used to clamp the spare tire's hub. The column 131 passes through the spare tire's axis, and the hooks 134 at each end of the clamping portion 132 engage the bolt holes in the spare tire's hub. Tightening the clamping portion 132 secures the spare tire.

[0051] In order to facilitate tightening the optional pressing part 132, the pressing part 132 is also provided with a handle 135. The handle 135 is fixedly arranged on the pressing part 132. By rotating the handle 135, the pressing part 132 is driven to rotate. The handle 135 is for the purpose of facilitating the rotation of the pressing part 132 and making it easy to hold.

[0052] The dedicated vehicle spare tire rack 10 further includes a fastening bottom plate 15. The fastening bottom plate 15 is provided at the connection between the first supporting portion 111 and the second supporting portion 121 and is located at the bottom of the storage space.

[0053] See Figure 4A slot 151 is provided on the fastening base plate 15, and a clip 133 is provided on one end of the column 131 near the first support portion 111. The clip 133 is square. The slot 151 is long and narrow. The slot 151 includes a large-diameter end 1511 and a small-diameter end 1512. The large-diameter end 1511 has a larger diameter so that the clip 133 can enter the slot 151. The slot 151 gradually decreases in diameter from the large-diameter end 1511 to the other end to form a small-diameter end 1512. The size of the small-diameter end 1512 can meet the sliding requirements of the column 131. The clip 133 is inserted from the large-diameter end 1511 of the slot 151, and the column 131 moves along the slot 151 to the small-diameter end 1512 and is engaged with the slot 151. The clip 133 and the small-diameter end 1512 of the slot 151 are stably fixed.

[0054] The fastening base plate 15 is in the shape of a right triangle, and a right-angled side 152 of the fastening base plate 15 is detachably connected to the second supporting portion 121 of the second connecting beam 12 .

[0055] The other right-angled side 153 of the fastening bottom plate 15 is detachably connected to the first supporting portion 111 of the first connecting beam 11. Specifically, the fastening bottom plate 15 is connected to the first connecting beam 11 and the second connecting beam 12 by screws.

[0056] Furthermore, the two right-angled sides 152 and 153 of the fastening base plate 15 are both provided with folded edges 154. The folded edges 154 are buckled with the first support portion 111 and the second support portion 121, and are fastened to the first support portion 111 and the second support portion 121 respectively by screws.

[0057] The fastening base plate 15 can be omitted, and the column 131 can be directly connected to the first connecting beam 11. The column 131 can be detachably connected to the first connecting beam 11 by screws, buckles, etc.

[0058] Furthermore, the connection point between the first connecting beam 11 and the second connecting beam 12 is biased to one side so that the fastening bottom plate 15 can be located in the middle of the storage space as much as possible, thereby ensuring a relatively stable placement of the spare tire.

[0059] Therefore, when the above-mentioned special vehicle spare tire rack is packaged and shipped, the first connecting beam 11, the second connecting beam 12, the fastening structure 13, the fastening base plate 15, and the connecting plate 110 can be disassembled and connected by bolts and screws. By removing the bolts and screws, the components can be disassembled and then sorted and packaged, saving the packaging space and logistics space of the special vehicle spare tire rack.

[0060] When a special-purpose vehicle carries two or more spare tires, two or more of the aforementioned spare tire racks are required. Furthermore, these two or more spare tire racks are mounted side by side horizontally at the bottom of the vehicle frame. The spare tire racks are arranged along the bottom surface of the vehicle frame, significantly reducing the longitudinal space occupied by the vehicle frame compared to carrying a single spare tire. Therefore, these spare tire racks effectively reduce the longitudinal space occupied by the vehicle frame, ensuring the vehicle's maneuverability.

[0061] The special-purpose vehicle and the special-purpose vehicle spare tire rack have simple structures, are easy to manufacture and install, are light in weight and low in cost, thus improving product competitiveness and being conducive to market promotion and application.
