Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a novel spare tire fixing structure for automobiles. Background Technology

[0002] In the automotive manufacturing industry, the spare tire is one of the essential components of a vehicle. Its fixing structure is crucial to ensuring the stability and safety of the spare tire during vehicle operation. However, the existing spare tire fixing structure is mainly bolt-fixed, that is, the spare tire is fixed to the bottom of the vehicle or a specific position in the trunk by bolts.

[0003] However, existing spare tire fixing structures for automobiles have some drawbacks in practical use. For example, during vehicle operation, especially when traversing bumpy roads, traditional fixing structures may loosen, causing the spare tire to wobble. With bolt-fixed systems, if the bolts loosen, the spare tire may shift or even fall off, posing a threat to vehicle safety. Summary of the Invention

[0004] In view of this, this application proposes a novel spare tire fixing structure for automobiles, which has the advantage of strong fixing stability and solves the problems mentioned in the background art.

[0006] The central fixed wheel has a circular structure with a star-shaped reinforcing structure at the center, which is distributed outwards from the center.

[0007] One end of the connecting arm is connected to the central fixed wheel, and the other end is connected to the mounting point in the trunk of the car.

[0008] The shock absorber is disposed between the central fixed wheel and the vehicle body, and is shaped like a "Z".

[0009] The adjustment device is mounted on the connecting arm;

[0010] The fixing assembly includes a fixing buckle and auxiliary fixing components. The fixing buckle is located on the right side of the connecting arm, and the auxiliary fixing components are located at both ends of the right side of the connecting arm, cooperating with the mounting point of the car trunk.

[0011] In one embodiment of the utility model, the star-shaped reinforcing structure is formed by multiple blade-like components that radiate outward from the center in a uniform manner, and the whole structure is symmetrically distributed, which can fit closely with the wheel hub.

[0012] In one embodiment of the utility model, the fixing buckle is a U-shaped clip structure, used to clamp the connecting arm and engage it with the trunk of a car.

[0013] In one embodiment of the utility model, there are two auxiliary fixing components, located at both ends on the right side of the connecting arm.

[0014] In one embodiment of the utility model, the adjusting device includes a screw and a nut, the screw being inserted into the adjusting hole of the connecting arm, and the effective length of the connecting arm being adjusted by rotating the nut.

[0015] In one embodiment of the utility model, the auxiliary fixing component is provided with a boss that cooperates with the mounting point of the car trunk.

[0016] In one embodiment of the utility model, bolt holes are provided on the central fixed wheel disk. The bolt holes are evenly distributed in a ring, and one bolt hole is provided between every two blade components of the star-shaped reinforcing structure.

[0017] In one embodiment of the utility model, the shock absorber is fixed from one end to the left side of the connecting arm, and the other end contacts the trunk of the car, thus playing a role in buffering and absorbing shock.

[0018] In one embodiment of the utility model, the connecting arm and the central fixed wheel are fixedly connected by welding.

[0019] In one embodiment of the utility model, the diameter of the central fixed wheel is adapted to the diameter of the spare tire center hole, and the position of the bolt hole corresponds one-to-one with the position of the bolt hole in the spare tire center hole.

[0020] The beneficial effects of this utility model are as follows: This novel spare tire fixing structure enhances overall strength and stability through a circular structure with a central fixed wheel disc and a star-shaped reinforcement design; the connecting arm ensures a stable connection between the spare tire and the trunk, and its square adjustment device allows for flexible adjustment of the length and shape of the connecting arm to accommodate various specifications; the "Z"-shaped shock absorber effectively buffers vibrations and prevents the spare tire from loosening and being damaged; the fixing buckle and auxiliary fixing device form multiple fixings to prevent the spare tire from shaking or shifting, comprehensively ensuring driving safety and the lifespan of the spare tire.

[0029] Specific references Figure 1As a novel spare tire fixing structure for automobiles according to this utility model, the device includes: a central fixing wheel 110, a connecting arm 120, a shock absorber 124, an adjusting device 123, and a fixing assembly; the central fixing wheel 110 has a circular plate-like structure, with a star-shaped reinforcing structure 112 at its center, which is distributed outwards from the center; the shock absorber 124 is disposed between the central fixing wheel 110 and the vehicle body, and is shaped like a "Z"; the adjusting device 123 is disposed on the connecting arm 120; the fixing assembly includes a fixing buckle 121 and an auxiliary fixing component 122, the fixing buckle 121 is disposed on the right side of the connecting arm 120, and the auxiliary fixing component 122 is disposed at both ends of the right side of the connecting arm 120, cooperating with the mounting point of the automobile trunk.

[0030] In this example, the star-shaped reinforcing structure 112 is formed by multiple blade-like components that radiate outwards from the center in a symmetrical manner. This structure matches the shape of the center hole of the spare tire hub, which can enhance the support rigidity of the wheel disc and effectively prevent radial swaying after the spare tire is installed.

[0031] In this example, the fixing buckle 121 is a U-shaped clamp structure, which is installed on the right side of the connecting arm 129 to clamp the connecting arm 120 and engage it with the trunk of the car, further fixing the connecting arm 120 and preventing it from loosening or shifting during vehicle operation.

[0032] In this example, there are two auxiliary fixing components 122, located at both ends of the right side of the connecting arm 120. Each auxiliary fixing component has a boss that cooperates with the corresponding mounting point in the car trunk to enhance the stability of the entire fixing structure and ensure that the connecting arm will not undergo lateral or longitudinal displacement during driving.

[0033] In this example, a plurality of bolt holes 111 are evenly distributed on the central fixed wheel 110. A bolt hole is provided between the blade components of every two star-shaped reinforcing structures 112. These bolt holes correspond one-to-one with the bolt hole positions of the spare tire center hole. By passing a bolt through the bolt holes of both and tightening it, the spare tire is securely fixed to the wheel 110.

[0034] In this example, a Z-shaped shock absorber 124 is installed on the left side of the connecting arm 120. One end of the shock absorber 124 is fixed to the connecting arm 120, and the other end contacts the trunk of the car. When the vehicle travels over bumpy roads, the shock absorber can effectively buffer the vibration and prevent the spare tire from becoming loose or damaging surrounding parts due to vibration.

[0035] In this example, the diameter of the central fixed wheel 110 is matched with the diameter of the spare tire center hole to ensure accurate positioning during installation.

[0036] In this example, the adjusting device 123 is installed in the middle of the connecting arm 120 and mainly consists of a screw and a nut. The screw passes through the adjusting hole of the connecting arm 120, and by rotating the nut, the effective length of the connecting arm can be adjusted to adapt to the trunk space of different vehicle models and the installation requirements of spare tires of different sizes.

[0037] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
