[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided, but those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0026] The spare tire anti-loosening and anti-theft device 100 according to a first aspect embodiment of the present invention is described below with reference to the accompanying drawings.

[0027] According to an embodiment of the present invention, the spare tire anti-loosening and anti-theft device 100, such as Figure 1 and Figure 2As shown, the spare tire anti-detachment and anti-theft device 100 is used to cooperate with the spare tire 200 on the vehicle. The spare tire anti-detachment and anti-theft device 100 includes a main body 1, an anti-detachment component 2, and an anti-theft component 3. The main body 1 is connected to the vehicle body, the anti-detachment component 2 is fixedly connected to the main body 1, and at least a portion of the anti-detachment component 2 extends under the spare tire 200 to support the spare tire 200. The anti-theft component 3 is detachably installed on the anti-detachment component 2. The anti-theft component 3 and the anti-detachment component 2 together lock and limit the spare tire 200. The anti-theft component 3 includes an irregularly shaped anti-theft structure, which is configured to be operated by a special tool.

[0028] To cope with emergencies such as tire blowouts and leaks, most cars are equipped with a spare tire. In related technologies, the spare tire is located outside the vehicle and stored and retrieved using a spare tire lifting mechanism. However, spare tires located outside the vehicle are susceptible to detachment and theft, indicating room for improvement.

[0029] Therefore, the present invention proposes a spare tire anti-detachment and anti-theft device 100. The spare tire anti-detachment and anti-theft device 100 of the present invention is used to reduce the risk of the spare tire 200 being detached and stolen.

[0030] The main body 1 is the connecting part between the spare tire anti-detachment and anti-theft device 100 and the vehicle body. One end of the main body 1 is connected to the vehicle body, and the other end of the main body 1 is fixedly connected to the anti-detachment component 2, thereby connecting the anti-detachment component 2 and the anti-theft component 3 to the vehicle body. For example, the main body 1 has a certain degree of flexibility, which can absorb the vibration generated during vehicle operation, reduce the degree of vibration transmission to the anti-detachment component 2 and the anti-theft component 3, and improve the working stability of the spare tire anti-detachment and anti-theft device 100.

[0031] The anti-detachment component 2 is fixedly connected to the main body component 1 and extends from the main body component 1 toward the spare tire 200. A portion of the anti-detachment component 2 extends below the spare tire 200, and this portion serves to support the spare tire 200. When the spare tire 200 detaches, it moves downwards until it contacts the anti-detachment component 2. The portion of the anti-detachment component 2 extending below the spare tire 200 mechanically interferes with the spare tire 200. The anti-detachment component 2 supports the spare tire 200 and restricts its downward movement, keeping the spare tire 200 near its storage position.

[0032] The anti-detachment component 2 maintains a definite connection with the vehicle body through the main body component 1. The anti-detachment component 2 forms a load-bearing path independent of the original constraint of the spare tire 200. Even if the original constraint of the spare tire 200 fails, the anti-detachment component 2 can still support the spare tire 200, thereby reducing the risk of the spare tire 200, which is located outside the vehicle, falling off.

[0033] For example, when the spare tire 200 is normally stored, the portion of the anti-detachment component 2 extending below the spare tire 200 maintains a predetermined gap with the spare tire 200, and the anti-detachment component 2 and the spare tire 200 are in a non-contact state. This can reduce friction and abnormal noise between the anti-detachment component 2 and the spare tire 200 during vehicle operation, and help extend the service life of the spare tire anti-detachment and anti-theft device 100.

[0034] The spare tire anti-detachment and anti-theft device 100 is also equipped with an anti-theft component 3, which is detachably installed on the anti-detachment component 2. When the anti-theft component 3 and the anti-detachment component 2 are installed together, the anti-theft component 3 and the anti-detachment component 2 together lock and limit the spare tire 200. When the anti-theft component 3 is removed from the anti-detachment component 2, the lock on the spare tire 200 can be released, and the spare tire 200 can be removed.

[0035] The anti-theft component 3 includes an irregularly shaped anti-theft structure. The outer contour of this structure is non-standard and does not match the working parts of conventional general-purpose tools. Therefore, the working parts of conventional general-purpose tools cannot effectively cooperate with the irregularly shaped anti-theft structure. A matching special tool is used to work with the irregularly shaped anti-theft structure, and force is applied to it, allowing the anti-theft component 3 to be quickly removed from the anti-detachment component 2. It is worth noting that the working parts of conventional general-purpose tools refer to the parts that directly contact the fasteners and transmit torque, such as the inner wall of a socket or the inner side of a wrench jaw.

[0036] In this way, without specialized tools, it is difficult for the operator to remove the anti-theft device 3 from the anti-detachment device 2, and it is also difficult to release the locking limit of the anti-theft device 3 and the anti-detachment device 2 on the spare tire 200. This reduces the risk of the spare tire 200, which is located on the outside of the vehicle, being stolen. It is understandable that it is not impossible to remove the anti-theft device 3 without specialized tools; for example, hydraulic pliers can be used to cut the irregularly shaped anti-theft structure directly, thereby removing the anti-theft device 3 from the anti-detachment device 2. Rather, without specialized tools, the operation of removing the anti-theft device 3 from the anti-detachment device 2 is more difficult and requires more complicated tools, greatly increasing the chance of the operator being discovered. This reduces the risk of the spare tire 200, which is located on the outside of the vehicle, being stolen.

[0037] Furthermore, the anti-theft component 3 and the anti-detachment component 2 are compactly arranged in structure and work together in function. The anti-theft component 3 is mainly used to deal with active disassembly, while the anti-detachment component 2 is mainly used to deal with passive loosening. Together, the anti-theft component 3 and the anti-detachment component 2 provide dual security for the spare tire 200. The compact arrangement of the anti-theft component 3 and the anti-detachment component 2 reduces the number of parts and the space occupied by the spare tire anti-detachment and anti-theft device 100 on the vehicle. It also requires only one installation operation during assembly, which helps to reduce manufacturing costs and improve assembly efficiency.

[0038] According to an embodiment of the present invention, the spare tire anti-detachment and anti-theft device 100 includes an anti-detachment component 2 and an anti-theft component 3. The anti-detachment component 2 has a portion that supports the spare tire 200 from below, thereby supporting the spare tire 200 when it falls off, reducing the risk of the spare tire 200 falling off. The anti-theft component 3 has an irregularly shaped anti-theft structure, making it difficult for the operator to remove the anti-theft component 3 from the anti-detachment component 2 without special tools, and also difficult to release the locking and limiting effect of the anti-theft component 3 and the anti-detachment component 2 on the spare tire 200, thereby reducing the risk of the spare tire 200 being stolen. Furthermore, the spare tire anti-detachment and anti-theft device 100 has a compact structure and few parts, which helps to improve assembly efficiency.

[0039] In some embodiments of the present invention, such as Figures 3-5 As shown, the anti-theft component 3 includes a bolt 31 and a nut 32. The anti-loosening component 2 has a threaded hole 21a. The head of the bolt 31 is located above the upper end face of the anti-loosening component 2. The shank 311 of the bolt 31 is threadedly engaged with the threaded hole 21a and extends out of the lower end face of the anti-loosening component 2. The nut 32 is threadedly connected to the shank 311 of the bolt 31. The nut 32 has an irregular anti-theft structure, and the outer contour of the nut 32 has an irregular structure.

[0040] The anti-detachment component 2 has a threaded hole 21a, which penetrates the anti-detachment component 2 along its thickness direction. The head of the bolt 31 is located above the upper end face of the anti-detachment component 2, and the shank 311 of the bolt 31 passes through the threaded hole 21a. The external thread of the shank 311 and the internal thread of the threaded hole 21a are engaged with each other. The bolt 31 and the anti-detachment component 2 are connected by the threaded engagement.

[0041] The head of bolt 31 is located above the anti-loosening component 2, and the head restricts the downward movement of bolt 31 relative to the anti-loosening component 2. The shank 311 of bolt 31 passes through the threaded hole 21a and extends out of the lower end face of the anti-loosening component 2. The part of the shank 311 extending out of the lower end face of the anti-loosening component 2 is located below the anti-loosening component 2.

[0042] Understandably, when assembling a spare tire, the upper part of the spare tire should be close to the vehicle body structure to minimize interference between the spare tire and the external environment. Therefore, bolt 31 is installed from top to bottom, with its head positioned above the upper surface of the anti-loosening component 2, i.e., above the spare tire, between the spare tire and the vehicle body structure. Firstly, this space is extremely small, making it difficult for tools to reach. Secondly, the external environment needs to pass through other structures to reach this space, which may act as obstructions, such as the spare tire itself. Therefore, no special modifications to the bolt are necessary, saving manufacturing costs.

[0043] Nut 32 is screwed onto the part of the rod 311 that extends out of the lower end face of the anti-detachment component 2. The head of bolt 31 and nut 32 are located on the upper and lower sides of spare tire 200, respectively. After nut 32 and bolt 31 are tightened, spare tire 200 is clamped between nut 32 and anti-detachment component 2, and nut 32 and anti-detachment component 2 jointly lock and limit spare tire 200. After nut 32 is loosened in the reverse direction, nut 32 is removed from bolt 31, and the constraint between spare tire 200 and nut 32 and anti-detachment component 2 is released.

[0044] The outer contour of nut 32 is an irregular shape, which does not match the working parts that can be engaged by conventional general-purpose tools. Therefore, the working parts of conventional general-purpose tools cannot effectively engage with the outer contour of nut 32. Even if the operator can access nut 32, a special tool compatible with the irregular shape is required to apply torque to nut 32 and rotate it relative to the shank 311 of bolt 31. This reduces the risk of the spare tire 200, located externally on the vehicle, being stolen.

[0045] It is worth noting that the anti-theft component 3 adopts a separate structure of bolt 31 and nut 32. Bolt 31 is threadedly engaged with anti-loosening component 2, and nut 32 is threadedly connected to the shank 311 of bolt 31. Spare tire 200 is clamped between nut 32 and anti-loosening component 2. Therefore, tightening nut 32 locks spare tire 200, and loosening nut 32 releases the lock. The locking and unlocking of spare tire 200 are accomplished by the same set of threaded parts. The anti-theft structure and the threaded connection structure are combined into a single part, nut 32, eliminating the need for a separate locking component. The number of parts in anti-theft component 3 and anti-loosening component 2 is small, and only one nut 32 needs to be tightened using a special tool during assembly, which reduces the difficulty of operation and improves operational efficiency.

[0046] In some embodiments of the present invention, such as Figure 5 and Figure 6 As shown, the outer contour of nut 32 is petal-shaped.

[0047] The outer contour of nut 32 alternately protrudes outward and inward in the circumferential direction of nut 32, and the outer contour as a whole presents a continuous petal shape.

[0048] Compared to the polygonal contours used in conventional fasteners, the petal-shaped contour lacks regular planes for general-purpose tools to grip at various points along the circumference, resulting in a lack of stable mating points between the nut 32 and the general-purpose tool. Understandably, conventional wrenches, sockets, and other general-purpose tools rely on the jaws or the inner wall of the socket to engage with two opposing planes on the outer contour of the nut 32, applying torque through these planes. With the petal-shaped outer contour of the nut 32, there are no two opposing planes for the jaws of a general-purpose tool to engage, making it difficult to establish stable surface contact between the tool and the nut 32. When the operator applies force to the nut 32, the tool easily slips off the outer contour, making it difficult to transmit the torque required to remove the spare tire 200 to the nut 32. A specialized tool with a working part compatible with the petal-shaped contour can establish stable surface contact with the nut 32 and transmit torque to it, improving operational efficiency.

[0049] In this way, the outer contour of the nut 32 is petal-shaped, making it difficult for conventional tools to form a stable fit with the nut 32. The matching special tool can apply torque to the nut 32, making it easy to remove the nut 32. The locking of the spare tire 200 by the anti-loosening component 2 and the anti-theft component 3 is not easily unlocked by operators without special tools, which helps to reduce the risk of the spare tire 200, which is located on the outside of the vehicle, being stolen.

[0050] In some embodiments of the present invention, the outer contour of the nut 32 is rotationally symmetrical with respect to the central axis of the nut 32. For each rotation of the nut 32 relative to the shank 311 of the bolt 31, the outer contour of the nut 32 coincides with the outer contour before the rotation. When the operator uses a special tool to tighten the nut 32, there is no need to find a specific initial angle, which makes it convenient to operate the nut 32 in the space below the spare tire 200.

[0051] In some embodiments of the present invention, such as Figure 5 and Figure 6 As shown, the nut 32 has eight petals 321, the outer end face of the petals 321 is an arc-shaped surface, and adjacent petals 321 are connected by a concave arc-shaped surface.

[0052] Eight petals 321 are distributed circumferentially along the nut 32. The outer end face of each petal 321 is an arc-shaped surface, meaning the surface of the petal 321 facing outwards towards the nut 32 is an outwardly convex arc-shaped surface. Adjacent petals 321 are connected by concave arc-shaped surfaces, and the arc-shaped surfaces between adjacent petals 321 are concave towards the inside of the nut 32. Thus, the outer contour of the nut 32 is formed by alternating convex and concave arc-shaped surfaces in the circumferential direction, with each junction on the outer contour being an arc-shaped transition.

[0053] The outer end face of the petal 321 is an arc-shaped surface, and two adjacent petals 321 are connected by an inwardly concave arc-shaped surface. All positions on the outer contour of the nut 32 are curved surfaces. There are neither two opposing planes on the outer contour for a general-purpose tool to fit against, nor corners that can be gripped by the jaws of a general-purpose tool. It is difficult for a general-purpose tool to find a stable force application point on the outer contour of the nut 32. A special tool whose shape matches the eight petals 321 can reliably fit with the nut 32 and transmit torque to the nut 32.

[0054] In this way, the outer contour of the nut 32 is composed of the outer end faces of eight lobes 321 and the concave arc-shaped surfaces between two adjacent lobes 321. There is no plane on the outer contour of the nut 32 for a general-purpose tool to clamp, making it difficult for a general-purpose tool to apply torque to the nut 32, which helps to reduce the risk of the spare tire 200 located outside the vehicle being stolen.

[0055] In some specific embodiments of the present invention, eight segments 321 are evenly distributed along the circumference of the nut 32, and the included angle between any two adjacent segments 321 is the same. After the special tool is rotated relative to the nut 32 through any angle corresponding to one of the segments 321, the fit between the special tool and the nut 32 remains unchanged. When the operator uses the special tool to tighten the nut 32, there is no need to find a specific initial angle, which facilitates operation of the nut 32 in the space below the spare tire 200.

[0056] In some embodiments of the present invention, such as Figure 1 As shown, the anti-theft component 3 also includes a rubber pad 33, which is sleeved on the shank 311 of the bolt 31 and sandwiched between the head of the bolt 31 and the anti-loosening component 2.

[0057] A rubber pad 33 is fitted onto the shank 311 of the bolt 31, and the rubber pad 33 surrounds the shank 311 circumferentially. The rubber pad 33 is located on the side where the upper end face of the anti-loosening component 2 is located, and the head of the bolt 31 abuts against the upper end face of the anti-loosening component 2 via the rubber pad 33, that is, the rubber pad 33 is clamped between the head of the bolt 31 and the upper end face of the anti-loosening component 2.

[0058] By placing a rubber pad 33 between the head of the bolt 31 and the anti-loosening component 2, the rubber pad 33 absorbs some of the vibration energy under vibration conditions and provides elastic preload between the head of the bolt 31 and the anti-loosening component 2. The locking state of the spare tire 200 is relatively stable during vehicle operation, which helps to improve the working reliability of the spare tire anti-loosening and anti-theft device 100. Furthermore, the rubber pad 33 has a simple structure and low cost. During assembly, it is only necessary to put the rubber pad 33 onto the shank 311 of the bolt 31, which reduces the number of assembly steps.

[0059] In some embodiments of the present invention, such as Figure 1 , Figure 3 and Figure 4 As shown, the anti-detachment component 2 includes a first plate portion 21, on which a threaded hole 21a is provided in the vertical direction. The first plate portion 21 is located above the spare tire 200. The bolt 31 passes through the first plate portion 21 and extends into the lower part of the spare tire 200. The nut 32 is threadedly connected to the shank portion 311 of the bolt 31 and is located below the spokes 210 of the spare tire 200.

[0060] The first plate portion 21 is the part of the anti-slip member 2 located above the spare tire 200. The bolt 31 passes through the first plate portion 21 and extends below the spokes 210 of the spare tire 200. The nut 32 is threadedly connected to the shank portion 311 of the bolt 31 and is located below the spokes 210 of the spare tire 200. Thus, the nut 32 moves axially along the shank portion 311 toward the spare tire 200 until it abuts against the spokes 210 of the spare tire 200 and is then tightened. The spare tire 200 is clamped between the first plate portion 21 and the nut 32, and the vertical position of the spare tire 200 relative to the anti-slip member 2 is determined.

[0061] In this way, the nut 32 can not only lock the spare tire 200, but also support the spare tire 200 below the spokes 210. The nut 32 abuts against the lower end face of the spokes 210. The cooperation of the nut 32 and the bolt 31 supports the spare tire 200 and restricts the downward movement of the spare tire 200, keeping the spare tire 200 near the storage position, which can further reduce the risk of the spare tire 200, which is located outside the vehicle, falling off.

[0062] The anti-theft component 3 and the anti-detachment component 2 work together in function. The anti-theft component 3 can also be used to deal with passive loosening. The anti-theft component 3 and the anti-detachment component 2 together constitute a double security guarantee for the spare tire 200, which is conducive to improving the working reliability of the spare tire anti-detachment and anti-theft device 100.

[0063] In some embodiments of the present invention, such as Figure 1 , Figure 3 and Figure 4 As shown, the anti-detachment component 2 also includes a second plate portion 22, which is located below the first plate portion 21 and below the spare tire 200. The second plate portion 22 is used to support the lower end face of the spoke 210 of the spare tire 200. The anti-detachment component 2 also includes a third plate portion 23, which passes through the spoke 210 and connects the first plate portion 21 and the second plate portion 22.

[0064] The second plate portion 22 is located below the first plate portion 21 and below the spare tire 200. After the spare tire 200 is stowed in place, the lower end face of the spokes 210 of the spare tire 200 faces downwards, and the upper end face of the second plate portion 22 is opposite to the lower end face of the spokes 210 of the spare tire 200. The second plate portion 22 supports the lower end face of the spokes 210 of the spare tire 200, that is, it supports the spokes 210 of the spare tire 200 from below. The first plate portion 21 is located above the spare tire 200, and the second plate portion 22 is located below the spare tire 200. The anti-slip member 2 has parts that mate with the spare tire 200 on both the upper and lower sides of the spare tire 200, thereby limiting the upper and lower movement of the spare tire 200.

[0065] The third plate 23 passes through the spokes 210. The upper end of the third plate 23 is connected to the first plate 21, and the lower end of the third plate 23 is connected to the second plate 22. The third plate 23 connects the first plate 21 located above the spare tire 200 and the second plate 22 located below the spare tire 200, thus forming the anti-detachment component 2 into a continuous integral structure.

[0066] In this way, the anti-detachment component 2 supports the lower end face of the spoke 210 of the spare tire 200 via the second plate portion 22, forming a support portion below the spare tire 200. If the original restraints of the spare tire 200 fail and the spare tire 200 moves downwards, the second plate portion 22 can support the spare tire 200 and limit its movement, thereby reducing the risk of the spare tire 200, which is located outside the vehicle, falling off.

[0067] Optionally, the first plate 21, the second plate 22 and the third plate 23 can be integrally formed. The strong integrity of the first plate 21, the second plate 22 and the third plate 23 is conducive to improving the structural stability of the anti-detachment part 2.

[0068] Alternatively, the first plate 21, the second plate 22, and the third plate 23 can be formed separately and then connected together.

[0069] In some embodiments of the present invention, when the spare tire 200 is normally stored, the second plate portion 22 is in clearance fit with the spokes 210 of the spare tire 200, and the distance between the second plate portion 22 and the spokes 210 of the spare tire 200 is 1mm-2mm. The second plate portion 22 and the spare tire 200 are in a non-contact state, thereby reducing the friction and abnormal noise generated between the second plate portion 22 and the spare tire 200.

[0070] Furthermore, the distance between the second plate portion 22 and the spokes 210 of the spare tire 200 is 1mm-2mm, which is relatively small. When the spare tire 200 moves downward relative to the vehicle body, the lower end face of the spokes 210 of the spare tire 200 only needs to move downward a very small distance to abut against the second plate portion 22. The second plate portion 22 can promptly support the spare tire 200 and limit its downward movement. Therefore, friction and abnormal noise are less likely to occur between the second plate portion 22 and the spokes 210 of the spare tire 200, and the anti-detachment component 2 can also promptly support the spare tire 200.

[0071] In the event that the spare tire lifting device 300 fails to restrain the spare tire 200, the weight of the spare tire 200 and the impact load during vehicle operation act on the clamping fit formed between the nut 32 and the first plate 21. This clamping fit is maintained by the tightening force of the nut 32 and the elastic preload of the rubber pad 33. When the load acting on this clamping fit causes relative slippage between the threaded fit between the nut 32 and the rod 311 of the bolt 31, and the nut 32 moves downward along the rod 311, the spoke 210 moves downward relative to the anti-loosening component 2, and the gap between the second plate 22 and the lower end face of the spoke 210 closes accordingly. After the lower end face of the spoke 210 moves downward by 1mm-2mm, it abuts against the second plate 22, and the second plate 22 begins to support the spoke 210 and restricts the downward movement of the spoke 210. In other words, the conditions for the second plate 22 and the wheel spoke 210 to close and for the second plate 22 to begin supporting the spare tire 200 are that the threaded engagement between the nut 32 and the shank 311 of the bolt 31 experiences relative slippage, and the wheel spoke 210 moves downward relative to the anti-slip member 2. Furthermore, the anti-slip member 2 is fixedly connected to the vehicle body via the main body 1, and the downward movement of the spare tire 200 relative to the vehicle body is equivalent to the downward movement of the wheel spoke 210 relative to the anti-slip member 2; both movements are simultaneous.

[0072] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the spare tire 200 has multiple through holes 2101 on its spokes 210. The bolts 31 and the third plate 23 both pass through the through holes 2101 to extend into the underside of the spokes 210. The anti-detachment component 2 and the anti-theft component 3 together limit the spare tire 200 in the vertical direction and together limit the spare tire 200 in the horizontal direction.

[0073] The spare tire 200 has multiple through holes 2101 on its spokes 210, which are spaced apart from each other. The bolt 31 and the third plate 23 both extend from the top of the spokes 210 to the bottom of the spokes 210 through the through holes 2101. The first plate 21 of the anti-detachment component 2 is located above the spare tire 200, the second plate 22 is located below the spare tire 200, and the third plate 23 passes through the through holes 2101 to connect the first plate 21 and the second plate 22. After passing through the through holes 2101, the bolt 31 is threadedly connected to the nut 32 located below the spokes 210.

[0074] The first plate 21 of the anti-slip component 2 is located above the spare tire 200, and the nut 32 of the anti-theft component 3 is located below the spare tire 200. The first plate 21 constrains the spare tire 200 from the upper side, and the nut 32 constrains the spare tire 200 from the lower side. Thus, the anti-slip component 2 and the anti-theft component 3 together limit the spare tire 200 in the vertical direction. Furthermore, the second plate 22 of the anti-slip component 2 is located below the spare tire 200, and the anti-slip component 2 can also limit the spare tire 200 in the vertical direction.

[0075] Bolt 31 passes through a through hole 2101 on the spoke 210, with the shank 311 located within the through hole 2101 and engaging with the wall of the through hole 2101. Third plate 23 also passes through the through hole 2101 on the spoke 210 and engages with the wall of the through hole 2101. Therefore, the horizontal movement range of the spare tire 200 is jointly limited by bolt 31 and third plate 23.

[0076] In this way, the movement of the spare tire 200 in the vertical direction is restricted, and the movement of the spare tire 200 in the horizontal direction is also restricted. The position of the spare tire 200 relative to the vehicle body is relatively stable, and the spare tire 200 is not easy to shake during vehicle operation, which can improve the installation stability of the spare tire 200.

[0077] In some embodiments of the present invention, such as Figure 3 and Figure 7 As shown, the through hole 2101 includes a first through hole 2101a, through which the bolt 31 passes to extend below the spoke 210, and the outer diameter of the nut 32 is larger than the diameter of the first through hole 2101a.

[0078] The shank 311 of bolt 31 passes through the first through hole 2101a and extends below the spoke 210. Nut 32 is located below the spoke 210 and is threadedly connected to the shank 311 of bolt 31. The first plate 21 of anti-slip member 2 and nut 32 are located on the upper and lower sides of spoke 210, respectively. Speaker 210 is clamped between the first plate 21 of anti-slip member 2 and nut 32. Nut 32 thus becomes a locking component for spare tire 200. That is, the position of spare tire 200 relative to anti-slip member 2 is determined by nut 32. To remove spare tire 200, nut 32 must first be unscrewed from the shank 311 of bolt 31 and removed from below spoke 210.

[0079] The outer diameter of nut 32 is larger than the diameter of the first through hole 2101a. Nut 32 cannot move from below the spoke 210 through the first through hole 2101a to above the spoke 210. Nut 32 is held on the shank 311 of bolt 31 below the spoke 210. Therefore, the position of spare tire 200 relative to anti-detachment component 2 can only be changed by rotating nut 32 relative to the shank 311 of bolt 31. Spare tire 200 cannot be detached from anti-detachment component 2 by pushing nut 32 or pushing spare tire 200. The locking relationship of anti-theft component 3 to spare tire 200 is not easily bypassed.

[0080] The nut 32 is constructed with an irregularly shaped anti-theft structure. The outer contour of the nut 32 is irregular, and its outer diameter is the maximum dimension of its outer contour. After the nut 32 is held below the wheel spokes 210, even if the operator can access the nut 32 below the wheel spokes 210 from outside the vehicle, a special tool compatible with the irregular structure is required to apply torque to the nut 32. Conventional tools are difficult to use effectively with the nut 32. Removing the lock of the anti-theft device 3 on the spare tire 200 requires a special tool. Without the special tool, it is difficult for an operator to remove the spare tire 200 from the spare tire anti-theft device 100, thereby reducing the risk of the spare tire 200, which is located outside the vehicle, being stolen.

[0081] In addition, the outer diameter of the nut 32 is larger than the diameter of the first through hole 2101a, and the nut 32 also serves to limit the position of the spare tire 200. The nut 32 is located below the wheel spoke 210 and abuts against the lower end face of the wheel spoke 210. The nut 32 cannot move upward through the first through hole 2101a from below the wheel spoke 210. Therefore, the nut 32 restricts the downward movement of the wheel spoke 210, keeping the spare tire 200 near the storage position, thereby reducing the risk of the spare tire 200, which is located outside the vehicle, falling off.

[0082] In some embodiments of the present invention, such as Figure 3 and Figure 7As shown, the via 2101 also includes a second via 2101b, the third plate portion 23 passes through the second via 2101b, the second plate portion 22 extends in a direction away from the anti-theft component 3, and the length of the second plate portion 22 is greater than the diameter of the second via 2101b.

[0083] The via 2101 also includes a second via 2101b, which is spaced apart from the first via 2101a and is formed on the spoke 210. The third plate portion 23 passes through the second via 2101b, and the upper end of the third plate portion 23 is connected to the first plate portion 21 located above the spoke 210, while the lower end of the third plate portion 23 is connected to the second plate portion 22 located below the spoke 210.

[0084] The second plate portion 22 extends away from the anti-theft component 3, that is, the second plate portion 22 extends from the position of the third plate portion 23 to the side away from the anti-theft component 3. The length of the second plate portion 22 is greater than the diameter of the second through hole 2101b. The projection of the second plate portion 22 in the vertical direction overlaps with the lower end face of the spoke 210. The second plate portion 22 cannot move directly upward through the second through hole 2101b in the vertical direction to the top of the spoke 210.

[0085] Therefore, the second plate 22 cannot be directly removed from the second through hole 2101b, and the spare tire 200 cannot be removed from the side where the anti-detachment component 2 is located. In other words, to remove the spare tire 200 from the spare tire anti-detachment and anti-theft device 100, the nut 32 must first be unscrewed from the rod 311 of the bolt 31 so that the spokes 210 are no longer clamped by the first plate 21 and the nut 32. Only then can the spare tire 200 be rotated so that the second plate 22 passes through the second through hole 2101b along its length, and the spare tire 200 can be removed.

[0086] The nut 32 has an irregular anti-theft structure. The special tool can apply torque to the nut 32, making it difficult for operators without the special tool to remove the nut 32, and thus difficult to remove the spare tire 200, thereby reducing the risk of the spare tire 200, which is located on the outside of the vehicle, being stolen.

[0087] Therefore, the anti-detachment component 2 and the anti-theft component 3 work together in terms of anti-theft function, and the operation of taking the spare tire 200 can only be carried out through the anti-theft component 3, which can improve the anti-theft performance of the spare tire anti-detachment and anti-theft device 100.

[0088] The anti-detachment component 2 and the anti-theft component 3 also work together to limit the movement of the spare tire 200. Vertically, the first plate 21 is located above the spare tire 200, and the nut 32 is located below the wheel spokes 210. The first plate 21 constrains the spare tire 200 from above, and the nut 32 constrains it from below, clamping the spare tire 200 between the first plate 21 and the nut 32. Furthermore, the second plate 22 is located below the wheel spokes 210, and both the first plate 21 and the second plate 22 limit the vertical movement of the spare tire 200.

[0089] In the horizontal direction, the shank 311 of bolt 31 passes through and is located within the first through hole 2101a, engaging with the wall of the first through hole 2101a. The third plate 23 passes through and is located within the second through hole 2101b, engaging with the wall of the second through hole 2101b. This restricts the horizontal movement range of the wheel spoke 210 relative to the anti-detachment component 2. The smaller horizontal movement range of the spare tire 200 prevents it from wobbling relative to the vehicle body during vehicle operation, thus improving the installation stability of the spare tire 200.

[0090] In some embodiments of the present invention, such as Figure 4 As shown, the first plate portion 21 includes a connecting section 211 located on the side of the third plate portion 23 closer to the anti-theft component 3, and the first plate portion 21 also includes a clearance section 212 located on the side of the third plate portion 23 away from the anti-theft component 3, the length of the clearance section 212 being less than half the length of the second plate portion 22.

[0091] The connection between the third plate portion 23 and the first plate portion 21 divides the first plate portion 21 into two parts. The part of the third plate portion 23 located on the side closer to the anti-theft component 3 is the connecting section 211, and the part of the third plate portion 23 located on the side farther away from the anti-theft component 3 is the clearance section 212. A threaded hole 21a is formed on the connecting section 211, which is used to cooperate with the bolt 31.

[0092] By designing the avoidance section 212 to be shorter, the spare tire 200 and the first plate 21 are less likely to interfere with each other during the assembly and disassembly of the spare tire 200 and the spare tire anti-detachment and anti-theft device 100, thus reducing the difficulty of operation.

[0093] It is worth noting that when installing the spare tire anti-detachment and anti-theft device 100 with the spare tire 200, the anti-detachment component 2 is first connected to the spare tire 200. At this time, both the anti-detachment component 2 and the spare tire 200 can move freely. Since the length of the second plate 22 is greater than the diameter of the second through hole 2101b, the anti-detachment component 2 is rotated relative to the spare tire 200, and the second plate 22 passes through the second through hole 2101b along its length. After passing through, the anti-detachment component 2 is rotated relative to the spare tire 200 again, so that the length of the second plate 22 extends horizontally. During the above two rotation processes, by designing the avoidance section 212 to be relatively short, the spare tire 200 and the first plate 21 are less likely to interfere, which helps to reduce the operational difficulty of assembling the spare tire 200 and the anti-detachment component 2.

[0094] Next, connect the anti-theft device 3 to the spare tire 200.

[0095] Similarly, when removing the spare tire 200 from the spare tire anti-theft device 100, the installation sequence is reversed.

[0096] First, disconnect the anti-theft device 3 from the spare tire 200 by unscrewing the nut 32 from the shank 311 of the bolt 31, and then remove the bolt 31 from the first through hole 2101a to disconnect the anti-theft device 3 from the spare tire 200.

[0097] Next, rotate the spare tire 200 or rotate the anti-detachment component 2 to rotate the second plate portion 22 located below the spare tire 200 to extend along the axial direction of the spare tire 200, so that the second plate portion passes through the second through hole 2101b along the length direction, and move the second plate portion 22 from below the spare tire 200 to above the spare tire 200, and the spare tire 200 is removed from the anti-detachment component 2.

[0098] In some embodiments of the present invention, such as Figure 4 As shown, the end of the avoidance section 212 is an arc-shaped surface, and the avoidance section 212 is connected to the third plate 23 in an arc transition, and the second plate 22 is connected to the third plate 23 in an arc transition.

[0099] The end of the clearance section 212 is an arc-shaped surface, meaning the end of the clearance section 212 has a smooth curved surface. Because the end of the clearance section 212 is arc-shaped, there are no sharp corners. This makes it less likely for the operator to be scratched when touching the end of the clearance section 212 during the removal of the spare tire 200. Furthermore, when the spare tire 200 rotates and comes into contact with the end of the clearance section 212, there is surface contact between the two, making it less likely for scratches to occur on the surface of the spare tire 200.

[0100] The connection between the clearance section 212 and the third plate 23, as well as between the second plate 22 and the third plate 23, is an arc-shaped transition. The connection between the clearance section 212 and the third plate 23, and the connection between the second plate 22 and the third plate 23, are the load-bearing parts on the anti-slip component 2. After the arc transition at the two connection points, the change in the direction of the load is relatively gentle when it is transmitted at the two connection points, and the stress concentration at the two connection points is small. When the anti-slip component 2 bears the weight of the spare tire 200, it is not easy for it to deform or crack at the bending point.

[0101] It is worth noting that the anti-detachment component 2 can be formed by bending a flat plate. The connection between the avoidance section 212 and the third plate 23, as well as the connection between the second plate 22 and the third plate 23, are all bending points of the anti-detachment component 2. By using an arc transition at the bending point, the structural strength of the anti-detachment component 2 can be improved, and the working stability of the anti-detachment component 2 can be enhanced.

[0102] In some embodiments of the present invention, the third plate portion 23 also passes through the first through hole 2101a, the second plate portion 22 extends in a direction away from the anti-theft member 3, and the maximum distance between the end of the second plate portion 22 away from the third plate portion 23 and the bolt 31 is greater than the diameter of the first through hole 2101a.

[0103] The shank 311 and the third plate 23 of bolt 31 pass through the spoke 210 via the same first through hole 2101a. The wall of the first through hole 2101a simultaneously constrains both the shank 311 and the third plate 23 of bolt 31. The second plate 22 extends away from the anti-theft component 3. The second plate 22 extends from the position of the third plate 23 away from the anti-theft component 3. The end of the second plate 22 away from the third plate 23 is the free end of the second plate 22. The maximum distance between the end of the second plate 22 away from the third plate 23 and bolt 31 is greater than the diameter of the first through hole 2101a. In other words, the maximum distance between the free end of the second plate 22 and bolt 31 is greater than the diameter of the first through hole 2101a. Therefore, the second plate 22 cannot be directly removed from the first through hole 2101a, and the spare tire 200 cannot be removed from the side where the anti-detachment component 2 is located.

[0104] In other words, to remove the spare tire 200 from the spare tire anti-theft device 100, the nut 32 must first be unscrewed from the shank 311 of the bolt 31, so that the wheel spokes 210 are no longer clamped by the first plate 21 and the nut 32. Only then can the spare tire 200 be removed from the anti-theft component 2. The nut 32 has an irregularly shaped anti-theft structure, and a special tool can apply torque to it. Operators without the special tool will find it difficult to remove the nut 32, and therefore difficult to remove the spare tire 200, thus reducing the risk of the spare tire 200 being stolen from the vehicle's exterior. Therefore, the anti-theft component 2 and the anti-theft component 3 work together in terms of anti-theft function. Removing the spare tire 200 can only be done through the anti-theft component 3, which improves the anti-theft performance of the spare tire anti-theft device 100.

[0105] The anti-detachment component 2 and the anti-theft component 3 also work together to limit the position of the spare tire 200. In the vertical direction, the first plate 21 is located above the spare tire 200, and the nut 32 is located below the wheel spokes 210. The first plate 21 constrains the spare tire 200 from the upper side, and the nut 32 constrains the spare tire 200 from the lower side. The spare tire 200 is clamped between the first plate 21 and the nut 32. Furthermore, the second plate 22 is located on the wheel spokes 210. Below the spoke 210, the maximum distance between the end of the second plate portion 22 away from the third plate portion 23 and the bolt 31 is greater than the diameter of the first through hole 2101a. The second plate portion 22 extends a large range below the spoke 210. When the spare tire 200 falls off, the spare tire 200 moves downward so that the lower end face of the spoke 210 abuts against the second plate portion 22. The second plate portion 22 supports the spare tire 200 and restricts the downward movement of the spare tire 200.

[0106] In the horizontal direction, the shank 311 and the third plate 23 of the bolt 31 pass through the spoke 210 via the same first through hole 2101a. The wall of the first through hole 2101a simultaneously constrains both the shank 311 and the third plate 23 of the bolt 31, thereby limiting the horizontal movement range of the spoke 210 relative to the anti-detachment component 2. The spare tire 200 has a smaller horizontal movement range, making it less prone to wobbling relative to the vehicle body during vehicle operation, thus improving the installation stability of the spare tire 200.

[0107] In some embodiments of the present invention, such as Figure 1 As shown, the main body 1 includes a fixing part 11 and an extension part 12. The fixing part 11 is fixedly connected to the vehicle body, and the extension part 12 is connected to the fixing part 11. The extension part 12 includes a steel wire rope and a rubber sheath. The steel wire rope connects the fixing part 11 and the anti-detachment component 2, and the rubber sheath covers the outside of the steel wire rope.

[0108] The fixing part 11 is fixedly connected to the vehicle body, and the main body 1 is constrained to the vehicle body by the fixing part 11. The extension part 12 is connected to the fixing part 11 and includes a steel wire rope. The steel wire rope connects the fixing part 11 and the anti-detachment component 2. The force borne by the anti-detachment component 2 and the anti-theft component 3 is transmitted to the fixing part 11 via the steel wire rope, and then transmitted to the vehicle body by the fixing part 11.

[0109] A rubber sheath covers the steel wire rope, extending along its length and surrounding it. As an elastic element, the sheath absorbs some of the vibrations generated during vehicle operation, reducing the vibrations transmitted to the steel wire rope and anti-loosening component 2, thus improving the operational stability of the spare tire anti-loosening and anti-theft device 100. Furthermore, the rubber sheath isolates the steel wire rope from the external environment, reducing corrosion and extending its service life.

[0110] In some embodiments of the present invention, the fixing part 11 includes a fixing ear plate with bolt holes. The fixing ear plate is fixedly connected to the vehicle body through the bolt holes. For example, fasteners pass through the bolt holes on the fixing ear plate and are connected to nuts on the vehicle body, thereby fixing the main body 1 to the vehicle body.

[0111] The extension 12 also includes a fixing joint, which integrally welds the wire rope and the fixing ear plate, resulting in a high connection strength between the wire rope and the fixing ear plate. The anti-detachment component 2 also includes a connector, one end of which is fixedly connected to the wire rope, and the other end of which is connected to other parts of the anti-detachment component 2.

[0112] In this way, the main body 1 is fixedly connected to the vehicle body via the fixing part 11 and connected to the anti-detachment part 2 via the extension part 12. The constraint reference of the anti-detachment part 2 and the anti-theft part 3 is established on the vehicle body. Even if the original constraint of the spare tire 200 fails, the anti-detachment part 2 can still support the spare tire 200, which can reduce the risk of the spare tire 200, which is located outside the vehicle, falling off. Furthermore, the extension part 12 adopts a composite structure of steel wire rope and rubber sheath. The steel wire rope bears the tension to ensure the load-bearing capacity of the extension part 12, and the rubber sheath absorbs vibration and reduces the corrosion of the steel wire rope, which can improve the working stability and service life of the spare tire anti-detachment and anti-theft device 100.

[0113] The following is a reference appendix. Figure 1-8 The structure and operation of a spare tire anti-loosening and anti-theft device 100 according to a specific embodiment of the present invention are described.

[0114] The spare tire 200 is stored outside the vehicle via a spare tire lifting device 300. The spare tire lifting device 300 includes a connector 310, which is connected to the center of the spokes 210 of the spare tire 200. The spokes 210 of the spare tire 200 are provided with multiple through holes 2101, including a first through hole 2101a and a second through hole 2101b.

[0115] The spare tire anti-detachment and anti-theft device 100 includes a main body 1, an anti-detachment component 2, an anti-theft component 3, and a fixing ring 4. The anti-detachment component 2 is fixedly connected to the main body 1, and the anti-theft component 3 is detachably installed on the anti-detachment component 2.

[0116] The main body 1 includes a fixing part 11 and an extension part 12. The fixing part 11 is fixedly connected to the vehicle body. The extension part 12 includes a steel wire rope, a rubber sheath, and a fixing joint. The fixing joint integrally welds the steel wire rope and the fixing ear plate. The rubber sheath covers the outside of the steel wire rope. The steel wire rope is connected to the anti-detachment component 2 via a connector. The fixing ring 4 is connected between the steel wire rope and the connector 310 of the spare tire lifting device 300.

[0117] The anti-slip component 2 includes a first plate portion 21, a second plate portion 22, and a third plate portion 23. The first plate portion 21 is located above the spokes 210 of the spare tire 200. The first plate portion 21 has a threaded hole 21a that runs vertically through it. The part of the first plate portion 21 located on the side of the third plate portion 23 closer to the anti-theft component 3 is a connecting section 211, and the part of the third plate portion 23 located on the side away from the anti-theft component 3 is a clearance section 212. The length of the clearance section 212 is less than half the length of the second plate portion 22. The end of the clearance section 212 is an arc-shaped surface. The clearance section 212 and the third plate portion 23, as well as the second plate portion 22 and the third plate portion 23, are connected by an arc-shaped transition. The third plate portion 23 extends downward from the first plate portion 21 through the second through hole 2101b on the spoke 210. The second plate portion 22 is located below the first plate portion 21 and below the spoke 210. The second plate portion 22 extends in a direction away from the anti-theft component 3. The length of the second plate portion 22 is greater than the diameter of the second through hole 2101b. The second plate portion 22 maintains a distance of 1mm-2mm from the lower end face of the spoke 210.

[0118] The anti-theft component 3 includes a bolt 31, a nut 32, and a rubber washer 33. The head of the bolt 31 is located above the first plate 21. The rubber washer 33 is fitted onto the shank 311 of the bolt 31 and sandwiched between the head of the bolt 31 and the first plate 21. The shank 311 of the bolt 31 passes through and is threaded into the threaded hole 21a on the first plate 21. After extending out of the lower end face of the first plate 21, the shank 311 passes through the first through hole 2101a on the spoke 210 and extends into the lower part of the spoke 210. The nut 32 is threadedly connected to the shank 311 of the bolt 31 and is located below the spoke 210. The outer diameter of the nut 32 is larger than the diameter of the first through hole 2101a. The outer contour of the nut 32 is petal-shaped, and the nut 32 has eight petals 321. The outer end face of the petal 321 is an arc-shaped surface. Adjacent petals 321 are connected by an inwardly concave arc-shaped surface. The nut 32 has an irregular anti-theft structure, and the nut 32 can be quickly removed by using a special tool.

[0119] During installation, first hang the spare tire 200 on the connector 310 of the spare tire lifting device 300, and then lift the spare tire 200 to the storage position through the spare tire lifting device 300. Next, connect the fixing ring 4 between the connector 310 of the spare tire lifting device 300 and the main body 1.

[0120] Then install the anti-slip component 2. First, align the second plate portion 22 along its length with the second through hole 2101b on the spoke 210, so that the second plate portion 22 and the third plate portion 23 pass through the second through hole 2101b in sequence, with the first plate portion 21 positioned above the spoke 210 and the second plate portion 22 reaching below the spoke 210. Then rotate the spare tire 200 so that the second plate portion 22 extends below the spoke 210, forming a gap of 1mm-2mm between the second plate portion 22 and the lower end face of the spoke 210. Next, pass the shank 311 of the bolt 31 through the threaded hole 21a on the first plate portion 21 and the first through hole 2101a on the spoke 210, so that the shank 311 of the bolt 31 extends below the spoke 210. Finally, using a special tool, screw the nut 32 onto the shank 311 of the bolt 31 and tighten it. The spokes 210 of the spare tire 200 are clamped between the first plate 21 and the nut 32, and the spare tire anti-detachment and anti-theft device 100 is installed.

[0121] When disassembling the spare tire 200, first remove the retaining ring 4 from between the connector 310 and the main body 1 of the spare tire lifting device 300, releasing the retaining ring 4 from the main body 1 and the connector 310. When the spare tire lifting device 300 is activated, the movement of the connector 310 will no longer drive the main body 1 and the anti-detachment component 2. Then, use a special tool to unscrew the nut 32 from the shank 311 of the bolt 31 and remove the nut 32 from below the spoke 210. Next, remove the bolt 31 from the threaded hole 21a on the first plate 21, so that the shank 311 of the bolt 31 exits from the first through hole 2101a on the spoke 210. Then, rotate the spare tire 200 so that the second plate 22 is aligned with the second through hole 2101b along its length, and remove the second plate 22 from below the spoke 210 through the second through hole 2101b. The constraint between the spare tire 200 and the anti-detachment component 2 is released. Finally, the spare tire 200 is removed using the spare tire lifting device 300 and taken off the spare tire anti-detachment and anti-theft device 100.

[0122] When the vehicle is in normal driving condition, the spokes 210 of the spare tire 200 are clamped between the first plate 21 and the nut 32. The second plate 22 maintains a distance of 1mm-2mm from the lower end face of the spokes 210. The second plate 22 and the spare tire 200 are in a non-contact state. There is no friction or abnormal noise between the anti-detachment component 2 and the spare tire 200. The shank 311 and the third plate 23 of the bolt 31 are located in the first through hole 2101a and the second through hole 2101b on the spokes 210, respectively. The range of movement of the spare tire 200 in the horizontal direction is restricted. When the spare tire lifting device 300 fails to restrain the spare tire 200 and the spare tire 200 moves downward, the wheel spoke 210 moves downward relative to the anti-detachment part 2, the gap between the second plate 22 and the lower end face of the wheel spoke 210 closes, the lower end face of the wheel spoke 210 abuts against the second plate 22, and the cooperation of the nut 32 and the bolt 31 also supports the spare tire 200, the downward movement of the spare tire 200 is restricted, and the spare tire 200 is kept near the storage position, thereby reducing the risk of the spare tire 200, which is located outside the vehicle, falling off.

[0123] According to a second aspect of the present invention, a vehicle includes a spare tire 200, a spare tire lifting device 300, and a spare tire anti-detachment and anti-theft device 100. The spare tire lifting device 300 includes a connector 310 connected to the center of the spokes 210 of the spare tire 200; the spare tire anti-detachment and anti-theft device 100 is the same as that according to a first aspect of the present invention, and further includes a retaining ring 4 connected between the connector 310 and the main body 1.

[0124] The spare tire 200 is located on the exterior of the vehicle, and the spare tire lifting device 300 is used for storing and removing the spare tire 200. The spare tire lifting device 300 includes a connector 310, which is connected to the center of the spokes 210 of the spare tire 200. The weight of the spare tire 200 is borne by the spare tire lifting device 300 via the connector 310. When the spare tire lifting device 300 is activated, the connector 310 moves the spare tire 200 up and down, thereby moving the spare tire 200 between a stored position and a lowered position.

[0125] The retaining ring 4 connects the extension 12 of the main body 1 to the connector 310 of the spare tire lifting device 300. Part of the weight of the spare tire 200 is transferred to the main body 1 via the retaining ring 4, and then from the main body 1 to the vehicle body. In other words, the spare tire anti-detachment and anti-theft device 100 is connected to the spare tire lifting device 300. The spare tire anti-detachment and anti-theft device 100 forms another load-bearing path outside the spare tire lifting device 300. The spare tire anti-detachment and anti-theft device 100 and the spare tire lifting device 300 jointly bear the weight of the spare tire 200, improving the connection stability of the spare tire 200. Furthermore, even if the constraint of the spare tire lifting device 300 on the spare tire 200 fails, the spare tire anti-detachment and anti-theft device 100 can still support the spare tire 200.

[0126] According to the vehicle of the present invention, by providing the spare tire anti-detachment and anti-theft device 100 of the first aspect embodiment described above, when the constraint of the spare tire lifting device 300 on the spare tire 200 fails, the spare tire anti-detachment and anti-theft device 100 can support the spare tire 200, and the spare tire anti-detachment and anti-theft device 100 is locked by the anti-theft component 3, which can further reduce the risk of the spare tire 200, which is arranged outside the vehicle, falling off and being stolen, and improve the overall performance of the vehicle.
