[0037] The spare tire rack device and the vehicle provided by the present invention are now described.

[0038] like Figures 1 to 4 As shown, the spare tire rack device provided by the first embodiment of the present invention includes a swing arm mounting base 10, a swing arm assembly 20, a spare tire mounting assembly 30 and a traction assembly. The swing arm mounting base 10 is used to be connected to the vehicle body 70; the swing arm assembly 20 is rotatably connected to the swing arm mounting base 10; the spare tire mounting assembly 30 is connected to the swing arm assembly 20 for mounting the spare tire 60; the traction assembly is connected to the swing arm assembly 20 or the spare tire mounting assembly 30 for retracting or releasing the swing arm assembly 20.

[0039] Compared with the prior art, the spare tire rack device provided in this embodiment is more convenient in that, when in use, the swing arm mounting base 10 and the swing arm assembly 20 are rotated together, and the swing arm assembly 20 is released by the pulling assembly, so that the spare tire mounting assembly 30 can be lowered to the ground under the vehicle. The spare tire 60 is then mounted on the spare tire mounting assembly 30, and the swing arm assembly 20 is retracted by the pulling assembly, so that the spare tire 60 is lifted and stored inside the vehicle body 70. When the spare tire 60 is needed, the swing arm assembly 20 is released by the pulling assembly, so that the spare tire 60 is lowered to the ground under the vehicle, and the spare tire 60 is removed from the spare tire mounting assembly 30. This makes it more convenient to remove and place the spare tire, avoiding the time and effort of getting in and out of the vehicle to remove and place the spare tire.

[0040] like Figures 1 to 10 As shown, the present invention provides a specific implementation method based on the first implementation method as follows.

[0041] like Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, the spare tire rack device also includes a spare tire support 50. The spare tire support 50 is used to be installed on the vehicle body 70 and is used to support the swing arm assembly 20 and / or the spare tire 60. This limits the angle of the swing arm assembly 20 and directs the swing arm assembly 20's rotation axis between the swing arm mounting base 10 and the swing arm assembly 20 toward the inner side of the vehicle body. In this way, the swing arm assembly 20 and the spare tire 60 can be pressed against the spare tire support 50 by gravity, making the swing arm assembly 20 more stable when stowed. To further enhance stability, the spare tire support 50 can be connected and fixed to the swing arm assembly 20 and / or the spare tire 60 by bolting, pinning, or snapping. To increase strength, a local reinforcement structure 22 is provided on the swing arm assembly 20 where it contacts the spare tire support 50.

[0042] like Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, a first limiting plate 11 is provided on the swing arm mounting seat 10, and a second limiting connecting plate 21 is provided on the swing arm assembly 20. The first limiting plate 11 and the second limiting connecting plate 21 are connected by limiting connecting parts such as bolts or spring pins, so that a fixed connection is formed between the swing arm mounting seat 10 and the swing arm assembly 20 to prevent the swing arm assembly 20 from moving around after being folded, which affects driving safety.

[0043] like Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, the swing arm assembly 20 includes a curved plate 23, a reinforcement plate 24, and a swing arm sleeve 25. The swing arm sleeve 25 is provided at one end of the curved plate 23 for rotational connection with the swing arm mounting base 10. The other end of the curved plate 23 is fixedly connected to the spare tire mounting assembly 30. The reinforcement plate 24 is perpendicular to the curved plate 23 to reinforce the curved plate 23. This structure can ensure the strength of the swing arm assembly 20 while reducing its weight. Moreover, by adjusting the curvature of the curved plate 23, the overall center of gravity can be lowered, allowing the spare tire 60 to be in a more suitable position after being stowed.

[0044] like Figure 1-4 、 Figure 5 and Figure 6 As shown, the swing arm mounting seat 10 includes a base 12, a mounting seat sleeve 13 and a flip pin 14. The base 12 is used to connect with the vehicle body 70; the mounting seat sleeve 13 is arranged on the base 12; the flip pin 14 is passed through the mounting seat sleeve 13 and the swing arm sleeve 25 to form a rotational connection between the base 12 and the curved plate 23.

[0045] In order to improve the connection strength, a plurality of mounting seat reinforcement plates 15 may be provided between the base 12 , the mounting seat sleeve 13 and the first limiting plate 11 .

[0046] like Figure 9 As shown, an oil filling cup 141 is provided at one end of the flip pin 14, and oil channels 142 are provided on the flip pin 14 at the locations adjacent to the mounting seat sleeve 13 and the swing arm sleeve 25. An oil channel 143 is provided inside the flip pin 14, which is connected to the oil filling cup 141 and the oil channel 142, to ensure lubrication of the rotating parts.

[0047] like Figure 1-4 、 Figure 7 and Figure 8 As shown, the spare tire mounting assembly 30 includes a mounting plate 31, a stud 32, a spare tire stop 33, a locking nut 34 and a limit pin 35. The mounting plate 31 is connected to the swing arm assembly 20; the stud 32 is provided on the mounting plate 31 to pass through the center hole of the spare tire 60; the spare tire stop 33 is passed through the stud 32 to block the spare tire 60; the locking nut 34 cooperates with the stud 32 to fix the spare tire stop 33 on the spare tire 60 to fix the spare tire 60; the limit pin 35 is provided on the mounting plate 31 to pass through the bolt hole in the spare tire 60 to limit the spare tire 60 and prevent the spare tire 60 from rotating.

[0048] In this manner, the spare tire 60 can be conveniently and firmly fixed, preventing the spare tire 60 from rotating and causing the locking nut 34 to loosen, thereby improving driving safety.

[0049] like Figure 10 As shown, the locking nut 34 is provided with several extended handles 341 , which are curved rod structures, with one end fixedly connected to the locking nut 34 and the other end extending outward, so that the user can twist the locking nut 34 more easily through the extended handles 341 .

[0050] like Figure 1-4 As shown, the traction assembly includes a winch 41, several pulley assemblies 43 and a traction rope 42. The winch 41 is used to be installed on the vehicle body 70; the several pulley assemblies 43 are used to be installed on the vehicle body 70; one end of the traction rope 42 is connected to the winch 41, the middle part passes around the several pulley assemblies 43, and the other end is connected to the swing arm assembly 20 or the spare tire mounting assembly 30.

[0051] The hoist 41 can be used to conveniently drive the swing arm assembly 20 to be folded or released, and the hoist 41 can be installed at a position on the vehicle body where the space is more suitable or the position is more convenient for operation through the guidance of the pulley assembly 43.

[0052] A second embodiment of the present invention provides a vehicle including the above-mentioned spare tire rack device.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
