Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0023] Example 1

[0024] like Figure 1-5 As shown, this is the first embodiment of the present invention. This embodiment provides a foldable spare tire cover for a car trunk, including a spare tire cover 100. The spare tire cover 100 is provided in three sets, and the three sets of spare tire cover 100 are hinged together to form a Z-shaped fold. The support assembly 200 includes a storage groove 210 located on both sides of the bottom of the spare tire cover 100, a support leg 220 located in the inner cavity of the storage groove 210, a limiting guide rail 230 for limiting and supporting the support leg 220, a sleeve 240 and a limiting connecting rod 250 for limiting the movement of the support leg 220, and a buckle 260 for fixing the support leg 220 when it is stored.

[0025] like Figure 1-5 As shown, the three sets of spare tire covers 100 are hinged to form a Z-shaped folding structure, which allows the whole to be folded and retracted segment by segment along the crease when not in use. Compared with the traditional one-piece flat structure, the Z-shaped folding can reduce the original length, greatly reduce the longitudinal space occupied, and adapt to the narrow trunk environment. The hinge connection ensures that the rotation angle between each segment is controllable, avoiding disorderly bending that may cause structural damage or operational difficulties.

[0026] The storage slots 210 in the support assembly 200 are located on both sides of the bottom of the spare tire cover 100, providing dedicated space for the outriggers 220. One end of the outrigger 220 is rotatably connected to the inner wall of the storage slot 210 via a pivot, allowing the outrigger 220 to rotate flexibly. It can be easily deployed when support is needed and conveniently retracted into the slot when stored. The limiting guide rail 230 is fixedly connected to the inner wall of the storage slot 210, providing precise guidance for the deployment and support of the outrigger 220, ensuring that the outrigger 220 does not deviate from the predetermined position during movement and guaranteeing the stability of the support. The sleeve 240 is fitted onto the surface of the outrigger 220 and fits tightly with it, moving as the outrigger 220 rotates. One end of the limiting link 250 is fixed to the sleeve 240. One end is connected to the other end, which is slidably connected to the inner cavity of the limiting guide rail 230. Through this connection method, the limiting link 250 can slide within the limiting guide rail 230 as the outrigger 220 moves, further limiting the range of motion of the outrigger 220 and enhancing the stability of the outrigger 220 in the supported state. The buckle 260 is fixedly connected to the inner wall of the storage slot 210. When the outrigger 220 is stored, its other end can be engaged with the inner cavity of the buckle 260, thereby firmly fixing the outrigger 220 in the storage slot 210, preventing the outrigger 220 from accidentally popping out during vehicle operation, and improving the safety of use. The unfolded spare tire cover 100 can be used as an outdoor travel table with the support of the support component 200, thereby increasing the functionality of the spare tire cover 100.

[0027] Example 2

[0028] Reference Figure 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0029] In this embodiment, the spare tire cover 100 includes a sandwich layer 110, a lower surface layer 120 located at the bottom of the sandwich layer 110, an upper surface layer 130 located at the top of the sandwich layer 110, a non-woven fabric layer 140 that wraps the sandwich layer 110, the lower surface layer 120 and the upper surface layer 130, and a cushioning sponge 150 fixed to both sides of the bottom of the spare tire cover 100.

[0030] The sandwich layer 110, the lower surface layer 120 and the upper surface layer 130 are bonded together with adhesive, and the bottom of the cushioning sponge 150 is in contact with the spare tire box.

[0031] The storage slot 210 is located at the bottom of the spare tire cover 100, and one end of the support leg 220 is rotatably connected to the inner wall of the storage slot 210 via a pivot.

[0032] The limiting guide rail 230 is fixedly connected to the inner wall of the storage groove 210, and the sleeve 240 is sleeved on the surface of the support leg 220.

[0033] One end of the limiting link 250 is fixedly connected to the sleeve 240, and the other end of the limiting link 250 is slidably connected to the inner cavity of the limiting guide rail 230.

[0034] The buckle 260 is fixedly connected to the inner wall of the storage slot 210, and the other end of the support leg 220 is engaged with the inner cavity of the buckle 260.

[0035] like Figure 1-5 As shown, the spare tire cover 100 adopts a multi-layer structure design, in which the sandwich layer 110 is located in the middle, providing the main strength support for the cover. The lower surface layer 120 and the upper surface layer 130 are located at the bottom and top of the sandwich layer 110, respectively, and are bonded to the sandwich layer 110 by adhesive. This bonding method ensures a tight bond between the layers and enhances the overall integrity of the cover.

[0036] The non-woven fabric layer 140 wraps the sandwich layer 110, the lower surface layer 120 and the upper surface layer 130, which not only protects each layer, but also makes the surface of the cover plate smoother and more beautiful. The cushioning sponge 150 fixed to the bottom sides of the spare tire cover plate 100 has its bottom in contact with the spare tire box. When the spare tire cover plate 100 is placed on the spare tire box, it can effectively reduce the friction and collision between the two.

[0037] The sandwich layer 110 can be made of any one of honeycomb paperboard, EPP foam, or XPS extruded board, which has the characteristics of high compressive strength and low density. The upper surface layer 130 and the lower surface layer 120 can be made of any one of PET, ABS, or PP sheets, which provides surface hardness and abrasion resistance. The non-woven fabric layer 140 is made of polyester fiber or polypropylene fiber to ensure surface flexibility and tear resistance. The cushioning sponge 150 is made of closed-cell EVA foam material, which has high resilience and aging resistance. The materials of each layer are compounded by hot melt adhesive or water-based adhesive to ensure environmental protection and bonding strength.

[0038] When in use, to unfold the spare tire cover 100, simply unfold the three sets of spare tire cover 100 along the hinge axis to form a flat support surface. Then, rotate the support leg 220 out of the storage slot 210. The sleeve 240 slides along the surface of the support leg 220, driving the limiting link 250 to move synchronously within the limiting guide rail 230. When the support leg 220 is unfolded to a vertical state, the limiting link 250 slides to the end of the limiting guide rail 230, forming a mechanical limit, thus completing the stable support. The unfolded spare tire cover 100 can be used as an outdoor travel table. When it needs to be stored, rotate the support leg 220 in the opposite direction to retract it into the storage slot 210. The support leg 220 is fixed by the buckle 260. The three sets of spare tire cover 100 can be quickly folded along the Z-shaped crease, finally forming a compact rectangular block, which is convenient to place on the side wall of the trunk or next to the spare tire box. The whole process can be completed with one hand.

[0039] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0040] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
