Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a spare tire support device. Background Technology

[0002] A spare tire, also known as a backup tire, is used to temporarily replace a tire that has been damaged during driving. Most cars carry a spare tire, which is the same size as the original tire. In the event of a tire blowout or other problems, the spare tire can be used to quickly replace the damaged tire, preventing the car from breaking down.

[0003] Depending on the vehicle model, the spare tire will be placed in different locations. For example, in common sedans, it is placed directly in the trunk, while off-road vehicles or large SVUs may use either under-mounted or rear-mounted spare tires. However, regardless of the method, when securing the spare tire, fasteners are passed through the center of the spare tire and then secured. The lack of a structure to limit the spare tire's position and provide lateral support can easily cause the spare tire to shift, which may then squeeze or collide with other parts of the vehicle, resulting in unnecessary damage.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a spare tire support device, including a base plate 1, a frustum support column 2 fixedly installed on the top of the base plate 1, the frustum support column 2 facing the central through hole of the spare tire, the frustum support column 2 being locked to the spare tire by a main fastener 4, side support frames 3 connected to the four sides of the base plate 1 by a spacing adjustment component 5, the top of the side support frame 3 having an L-shaped inclined slope 301, the edge of the spare tire abutting against the L-shaped inclined slope 301, mounting holes connecting the base plate 1 and the vehicle being opened at the four corners of the base plate 1, the frustum support column 2 being inserted into the central through hole of the spare tire to support the spare tire and position its center, and then the four side support frames 3 supporting the spare tire. The spare tire is locked to the frustum support column 2 by the main fastener 4. The frustum support column 2 and the side support frame 3 form a support and limiting structure. When the spare tire is mounted on the back, the frustum support column 2 and one side support frame 3 can support the spare tire, while the other three side support frames 3 limit the spare tire, which can effectively prevent the spare tire from shifting position. When the spare tire is mounted on the bottom or placed in the trunk, the four side support frames 3 serve the purpose of limiting the position, which can also prevent the spare tire from shifting position. The bottom plate 1 and the side support frame 3 are connected by the spacing adjustment component 5, which is used to adjust the position of the side support frame 3 according to the size of the spare tire, so as to ensure that when the spare tire is supported by the frustum support column 2, it can also rest on the L-shaped inclined slope 301.

[0022] The main fastener 4 includes a threaded rod 401, which is fixedly installed on the top of the base plate 1. The threaded rod 401 passes through the central through hole of the spare tire. A pressure plate 404 is slidably sleeved on the outer wall of the threaded rod 401. A hexagonal nut 402 is threadedly sleeved on the outer wall of the threaded rod 401. The pressure plate 404 presses on the spare tire. An elastic washer 403 is slidably sleeved on the threaded rod 401. The elastic washer 403 presses on the pressure plate 404. The hexagonal nut 402 presses on the elastic washer 403. By rotating the hexagonal nut 402, the elastic washer 403 is pushed down, which in turn drives the pressure plate 404 down, pressing the pressure plate 404 tightly on the spare tire. The downward pressure of the pressure plate 404 on the spare tire will also press the spare tire tightly on the frustum support column 2 and the L-shaped inclined slope 301.

[0023] The spacing adjustment assembly 5 includes a threaded rod 501 and a connecting column 504. The threaded rod 501 is fixedly installed on the outer side wall of the base plate 1. The outer wall of the threaded rod 501 is threaded with an internal threaded tube 502. The outer wall of the internal threaded tube 502 is rotatably fitted with a J-type connecting rod 503. The end of the J-type connecting rod 503 away from the base plate 1 is fixedly connected to the bottom of the connecting column 504. Both ends of the internal threaded tube 502 are provided with outward extensions, and the diameter of the extensions is larger than the diameter of the internal threaded tube 502. The top of the connecting column 504 is fixedly installed with a threaded rod 505. The threaded rod 505 passes through the inner wall of the top of the side support frame 3 and is locked to the side support frame 3 by a nut. The threaded rod 505 connects the connecting column 504 and the side support frame 3, thereby connecting the side support frame 3 and the J-type connecting rod 503. By rotating the internal threaded tube 502, the position of the J-type connecting rod 503 is adjusted, thereby adjusting the position of the side support frame 3.

[0024] The top of the hex nut 402 is fixedly connected to an internal hex block 8. The internal hex block 8 is provided so that it can be turned with an internal hex wrench, thereby turning the hex nut 402. The edge of the pressure plate 404 is provided with an integrally formed extension body 9. The extension body 9 has a threaded hole 901. The extension body 9 and the threaded hole 901 are provided for installing other things on the pressure plate 404, such as a license plate mounting bracket.

[0025] The outer wall of the connecting column 504 is fixedly fitted with an inner support body 7. The inner support body 7 is located inside the side support frame 3 and is supported inside the side support frame 3. The inner support body 7 is used to support the side support frame 3 from the inside of the side support frame 3 to increase the deformation resistance of the side support frame 3.

[0026] A hexagonal sleeve 6 is fixedly connected to one end of the internally threaded tube 502 away from the J-type connecting rod 503. The hexagonal sleeve 6 is slidably fitted on the threaded rod 501. The hexagonal sleeve 6 is used to rotate the internally threaded tube 502, and its shape also makes it easy to rotate with a wrench.

[0027] Working principle: In use, according to the size of the spare tire, rotating the hexagonal sleeve 6 drives the internal threaded tube 502 to rotate, causing the internal threaded tube 502 to move the J-shaped connecting rod 503, which in turn moves the connecting column 504 and the threaded rod 505. The movement of the threaded rod 505 moves the side support frame 3, so that the distance between the side support frame 3 and the truncated cone support column 2 matches the size of the spare tire. Then, the spare tire is placed on the truncated cone support column 2 and the L-shaped inclined slope 301. When placing it, the center through hole of the spare tire is aligned with the truncated cone support column 2. After placement, the pressure plate 404 and the elastic washer 403 are sequentially put on the threaded rod 401, and then the hexagonal nut 402 is tightened. Rotating the hexagonal nut 402 causes the hexagonal nut 402 to push the elastic washer 403 to move, which in turn pushes the pressure plate 404 to move until the pressure plate 404 presses tightly on the spare tire. At this time, the four side support frames 3 also support and limit the spare tire, which can effectively prevent the spare tire from shifting and colliding with other parts of the car.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
