[0053] In one embodiment, a first retaining edge 301 is disposed on the periphery of the supporting member 300 to prevent the spare tire from slipping out from between the supporting member 300 and the vehicle frame.

[0054] Combination Figure 1 and Figure 3 In the embodiment of the utility model, the periphery of the supporting member 300 is provided with a first retaining edge 301. When the spare tire is placed on the supporting surface, the first retaining edge 301 can prevent the spare tire from moving outward from the supporting member 300, thereby preventing the spare tire from falling off between the supporting member 300 and the vehicle frame, and preventing the spare tire from being disengaged from the fixed position due to vibration during the driving of the vehicle, thereby improving the firmness and safety of the spare tire fixation. Specifically in this embodiment, the supporting member 300 provided with the first retaining edge 301 is disc-shaped, and the shape and size of the supporting member 300 match the outer shape of the spare tire, with a simple structure, easy to manufacture, and low processing cost.

[0055] In one embodiment, the spare tire fixing device also includes a protective member, which is arranged on the side of the frame facing the bracket assembly 100. The side of the protective member facing the bracket assembly 100 is provided with a contact surface for contacting the spare tire. In the fixed position, the supporting member 300 and the protective member clamp both sides of the spare tire.

[0056] In an embodiment of the present utility model, the protective member is arranged on the side of the bracket assembly 100 facing the vehicle frame. When the bracket assembly 100 is in a fixed position, the supporting member 300 and the protective member jointly clamp the upper and lower sides of the spare tire, ensuring that the spare tire is firmly fixed. Moreover, the protective member contacts the spare tire through the contact surface, and the contact area between the protective member and the spare tire is large, avoiding the vehicle frame leaving indentations on the surface of the spare tire, further ensuring the durability of the spare tire and extending its service life.

[0057] In one embodiment, a second edge is provided on the periphery of the protective member to prevent the spare tire from slipping out between the supporting member 300 and the protective member; and / or,

[0058] At least one of the supporting member 300 and the protective member is provided with a weight-reducing hole 302.

[0059] In an embodiment of the present utility model, a second edge is provided on the periphery of the protective member. When the spare tire is placed between the supporting member 300 and the protective member, the second edge can prevent the spare tire from moving outward relative to the protective member, thereby preventing the spare tire from falling off between the supporting member 300 and the protective member, and avoiding the spare tire being disengaged from the fixed position due to vibration during vehicle driving, improving the firmness and safety of the spare tire fixation. Specifically in this embodiment, the shape and size of the protective member are the same as those of the supporting member 300, presenting an inverted disc shape, with a simple structure, easy to manufacture, reducing the types of parts and having a low processing cost.

[0060] In an embodiment of the present utility model, referring to Figure 5 , a weight-reducing hole 302 can be provided on the supporting member 300 to reduce the weight of the supporting member 300; or a weight-reducing hole 302 can be provided on the protective member to reduce the weight of the protective member. By providing the weight-reducing hole 302, the spare tire fixing device is made more lightweight, improving the convenience during assembly and use.

[0061] In one embodiment, the locking assembly 200 includes:

[0062] A hook 210; and

[0063] A locking member 220, provided with a hanging hole corresponding to the hook 210. One of the hook 210 and the locking member 220 is arranged on the vehicle frame, and the other of the hook 210 and the locking member 220 is arranged on the bracket assembly 100;

[0064] Wherein, the hook 210 passes through the hanging hole so that the locking assembly 200 is in a locked state, and the hook 210 disengages from the hanging hole so that the locking assembly 200 is in an unlocked state.

[0065] Referring to Figure 2, in the embodiment of the present utility model, the locking assembly 200 includes a hook 210 and a locking member 220. It can be realized by arranging the hook 210 on the vehicle frame and the locking member 220 on the bracket assembly 100, or by arranging the locking member 220 on the vehicle frame and the hook 210 on the bracket assembly 100. A hanging hole corresponding to the hook 210 is provided on the locking member 220. When the hook 210 is inserted into the hanging hole, the hook 210 and the locking member 220 are connected together, thereby locking the bracket assembly 100 to the vehicle frame and preventing the bracket assembly 100 from rotating; when the hook 210 withdraws from the hanging hole, the hook 210 is separated from the locking member 220, and the bracket assembly 100 can rotate relative to the vehicle frame. The structure of the locking assembly 200 is simple, easy to manufacture, and has a low manufacturing cost.

[0066] In an embodiment, the hook 210 is arranged on the vehicle frame. The spare tire fixing device further includes an adjusting assembly 400 arranged on the bracket assembly 100. The locking member 220 has opposite first and second ends. The first end is provided with a hanging hole, and the second end is movably inserted through the adjusting assembly 400. The adjusting assembly 400 is used to adjust the distance that the first end extends out of the adjusting assembly 400.

[0067] Refer to Figures 3 to 4, in the embodiment of the present utility model, the locking assembly 200 is configured by providing a locking member 220 on the vehicle frame and a hook 210 on the bracket assembly 100. The spare tire fixing device further includes an adjusting assembly 400. A hanging hole is provided at the first end of the locking member 220, and the second end is passed through the adjusting assembly 400. The distance that the first end extends out of the adjusting assembly 400 can be adjusted through the adjusting assembly 400. Specifically, when the hook 210 is inserted into the hanging hole, the distance that the locking member 220 extends out of the adjusting assembly 400 generally corresponds to the thickness of the spare tire, which not only prevents the spare tire from shaking up and down in the bracket assembly 100 but also prevents the hook 210 from disengaging from the hanging hole during vehicle driving; when it is necessary to disengage the hook 210 from the hanging hole, the distance that the locking member 220 extends out of the adjusting assembly 400 can be increased through the adjusting assembly 400, so that the bracket assembly 100 can be slightly flipped to drive the locking member 220 to move up and down, thereby disengaging the hook 210 from the hanging hole; when it is necessary to insert the hook 210 into the hanging hole again, at this time, the distance that the locking member 220 extends out of the adjusting assembly 400 is greater than the thickness of the spare tire, which is convenient for operating the hook 210 to be inserted into the hanging hole; after the hook 210 is inserted into the hanging hole, in order to prevent the spare tire from shaking up and down and the hook 210 from bumping out, at this time, the distance that the locking member 220 extends out of the adjusting assembly 400 can be reduced through the adjusting assembly 400, so that the distance that the locking member 220 extends out of the adjusting assembly 400 corresponds to the thickness of the spare tire again, thereby fixing the spare tire firmly. Among them, the adjustment of the extension height of the locking member 220 can be achieved by threading the locking member 220 and the adjusting assembly 400, or by providing protrusions on the outer wall of the locking member 220 and providing a plurality of grooves corresponding to the protrusions along the height direction on the adjusting assembly 400, and the different extension heights of the locking member 220 are realized by inserting the protrusions into different grooves.

[0068] In one embodiment, the adjusting assembly 400 includes:

[0069] A mounting member 410, provided on the bracket assembly 100. The mounting member 410 is provided with a through hole, and the outer peripheral wall of the second end is provided with an external thread and passes through the through hole;

[0070] A first nut 420, provided on the side of the mounting member 410 away from the hook 210. The first nut 420 is threadedly connected to the locking member 220, and the distance that the first end extends out of the adjusting assembly 400 is adjusted by rotating the first nut 420.

[0071] Refer to Figure 4In the embodiment of the utility model, the adjustment component 400 includes a mounting member 410 and a first nut 420. The mounting member 410 is fixed on the bracket assembly 100. The first nut 420 is arranged on the side of the mounting member 410 away from the hook 210. By adjusting the position of the first nut 420 on the locking member 220, the relative position of the mounting member 410 and the locking member 220 is changed, so that the height of the locking member 220 extending out of the adjustment component 400 can be adjusted. For example, when the first nut 420 is screwed toward the direction close to the ground, the mounting member 410 can drive the bracket assembly 100 downward, which is equivalent to the height of the locking member 220 extending out of the mounting member 410 increasing. The adjustment component 400 in this embodiment has a simple structure, is easy to implement, and has low cost.

[0072] In one embodiment, the adjustment assembly 400 further includes a second nut 430, which is disposed on a side of the mounting member 410 away from the first nut 420 and is threadedly connected to the locking member 220, and is used to clamp the mounting member 410 with the first nut 420; and / or,

[0073] The adjustment assembly 400 further includes a third nut 440 , which is disposed on a side of the first nut 420 away from the mounting member 410 and is threadedly connected to the locking member 220 , and is used to prevent the first nut 420 from moving in a direction away from the mounting member 410 .

[0074] Reference Figure 4 In an embodiment of the utility model, the adjustment assembly 400 also includes a second nut 430, and the second nut 430 is arranged on the side of the mounting member 410 away from the first nut 420. The first nut 420 and the second nut 430 are screwed in a direction approaching each other, so that the mounting member 410 can be clamped and locked to prevent the mounting member 410 from shaking up and down during the driving of the vehicle, thereby ensuring the stability of the locking assembly 200 and the bracket assembly 100, and thus improving the stability of the spare tire fixation.

[0075] Reference Figure 4 In an embodiment of the utility model, the adjustment assembly 400 also includes a third nut 440, which prevents the first nut 420 from loosening, ensures the stability of the relative position of the locking member 220 and the mounting member 410, thereby ensuring the reliability of the locking assembly 200 when it is in a locked state, reducing the possibility of accidental unlocking of the locking assembly 200, and thus improving the safety of the spare tire fixing device.

[0076] In one embodiment, the bracket assembly 100 includes:

[0077] A vertical support 110, one end of which is rotatably connected to the frame, and the other end of which extends toward the ground, and two vertical supports 110 are provided at intervals;
