[0070] Embodiment 4
[0071] As Figure 1 and Figure 2 As shown, this embodiment provides a spare tire mounting structure, including a spare tire fixing bracket 400, a spare wheel carrier 300, and a spare wheel carrier mounting bracket. The spare tire fixing bracket 400 is installed at the bottom of the rear floor 200; the spare wheel carrier 300 is located below the spare tire fixing bracket 400 and is detachably connected to the rear floor 200 through the spare wheel carrier mounting bracket; the spare tire 100 is installed in the spare wheel carrier 300 and connected to the spare tire fixing bracket 400. This structure has a lightweight design, is simple in structure, and is convenient for installation and disassembly.
[0072] The difference between this embodiment and the above embodiments is that:
[0073] As Figure 8As shown in the figure, the spare tire 100 is connected to the spare tire fixing bracket 400 through the spare tire bracket 600, which facilitates the fixing of the spare tire 100 on the spare tire fixing bracket 400. One end of the spare tire bracket 600 is connected to the spare tire fixing bracket 400 through the third bolt, and the other end of the spare tire bracket 600 is connected to the spare tire 100 through the disassembly and assembly tool 800.
[0074] Specifically, the spare tire bracket 600 includes a bracket support 603, a fixing plate 602, and a limiting block 601 that are connected in sequence from top to bottom. A third bolt installation space is formed between the bracket support 603 and the fixing plate 602. The third bolt is pre-hung on the bracket support 603. The spare tire 100 is provided with a limiting block installation hole that cooperates with the limiting block 601. The limiting block 601 has a through hole 6011 from top to bottom. A tool installation hole is opened on the fixing plate 602. The disassembly and assembly tool passes through the through hole 6011 and the tool installation hole and is connected to the fixing plate 602.
[0075] The bracket support 603 is in a "C" shape, which increases the axial space and reserves enough space for the connection between the bracket support and the spare tire fixing bracket 400 through the third bolt.
[0076] The fixing plate 602 is preferably a circular steel plate.
[0077] The cross-section of the limiting block 601 is circular, and the material is rubber, which facilitates the installation and fixing of the inner hole of the spare tire 100 and the limiting block 601, and the friction between the two is large, avoiding the downward sliding of the spare tire.
[0078] A through hole 6011 is opened inside the limiting block 601, and the disassembly and assembly tool 800 is inserted into the through hole 6011 to temporarily fix the spare tire 100.
[0079] As Figure 9 shown in the figure, the disassembly and assembly tool 800 is provided with a limiting post and a block connected below the limiting post. The shape of the limiting post is adapted to the through hole 6011, and the block can limit the spare tire 100 from disengaging from the limiting block 601 along the axis.
[0080] The central axis of the spare tire 100 is installed deviating from the central axis of the rear floor 200.
[0081] Specifically, the spare tire and the spare tire installation structure are arranged below the rear part of the rear floor 200, offset to the left side, and a space is left on the right side to arrange the exhaust (fuel version and hybrid version) or other parts (pure electric version).
[0082] The installation and disassembly process of the spare tire using a spare tire installation structure of the present invention is as follows:
[0083] When installing the spare tire 100:
[0084] First, connect the spare tire bracket 600 to the spare tire fixing bracket 400 through the third bolt. Then, use a manipulator to lift the spare tire 100 to the specified position, so that the limit block 601 of the spare tire bracket 600 penetrates into the inner hole of the spare tire 100. Next, insert the disassembly and assembly tool 800 into the hole 6011 to temporarily fix the position of the spare tire 100, and then withdraw the manipulator. Hook the spare wheel rack 300 to the hook part 3011, and then rotate the first bolt 3012 downward. The lower end of the first bolt 3012 abuts against the upper part of the spare wheel rack 300 to prevent the spare wheel rack 300 from unhooking. Finally, remove the disassembly and assembly tool 800.
[0085] When disassembling the spare tire 100:
[0086] Rotate the first bolt 3012 upward to unhook the spare wheel rack 300. The spare wheel rack 300 tilts downward under the action of gravity, leaving a space for disassembling the spare tire 100. Rotate the spare tire 100 downward to complete the disassembly of the spare tire 100.
