Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a shock-absorbing and anti-slip spare tire cover for automobiles. Background Technology

[0002] The spare tire cover in a car trunk is an important interior component that covers the spare tire, primarily used to conceal the spare tire, keep the trunk tidy, and provide additional storage space. Traditional covers typically consist of a multi-layered structure, including an outer decorative material (such as non-woven fabric or PVC leather), a middle support layer (such as MDF fiberboard or PP honeycomb board), and a bottom anti-slip mat (such as rubber or EVA foam). Its design must balance load-bearing capacity, lightweight construction, and aesthetics to ensure convenience and durability for daily use.

[0003] However, existing spare tire covers still suffer from insufficient shock absorption, mediocre anti-slip performance, and excessive weight. Specifically: the rigid support layer (such as MDF) cannot effectively absorb vibrations; when items are placed on the cover and the vehicle encounters bumps, it fails to provide adequate shock absorption, easily leading to damage. The bottom layer uses only a simple rubber pad, which is prone to shifting during vehicle bumps and offers insufficient anti-slip properties. The surface material is easily worn, and may deform or crack after prolonged use; furthermore, damage to the surface layer necessitates replacing the entire cover, increasing operating costs. Contaminated surfaces require the entire cover to be removed from the trunk for cleaning. To address these shortcomings, the design needs to be optimized to improve shock absorption and anti-slip performance, thereby enhancing driving comfort. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a shock-absorbing and anti-slip car spare tire cover.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a shock-absorbing and anti-slip car spare tire cover, comprising a structural support layer, an intermediate buffer layer fixedly connected to the upper surface of the structural support layer, a detachable surface layer fixed to the upper surface of the intermediate buffer layer, a wear-resistant and anti-slip layer provided on the upper surface of the surface layer, and a strong anti-slip layer fixed to the lower surface of the structural support layer, the strong anti-slip layer being arranged along the side of the lower surface of the structural support layer in a ring shape.

[0006] Furthermore, the strong anti-slip layer and the structural support layer, as well as the intermediate buffer layer and the structural support layer, are all bonded and fixed with adhesive.

[0007] Furthermore, the wear-resistant and anti-slip layer is a coating.

[0008] Furthermore, the structural support layer has multiple screw holes on its side, and the intermediate buffer layer and the surface layer each have multiple through holes corresponding to the screw holes on their side. Bolts are provided to match the multiple screw holes, with a knob fixed to the top of the bolt and the bottom of the bolt passing through the through hole and screwed into the screw hole.

[0009] Furthermore, multiple Velcro straps are fixed to the upper surface side of the intermediate buffer layer and the lower surface side of the surface layer, with the Velcro straps on the intermediate buffer layer and the surface layer having a hook side and a rough side, respectively.

[0010] Furthermore, the strong anti-slip layer is made of magnetic sheet material.

[0011] Furthermore, a handle is fixed to the upper surface of the surface layer.

[0012] The beneficial effects of this utility model are:

[0013] 1. In use, this utility model provides a shock-absorbing and anti-slip car spare tire cover, which is composed of a structural support layer, an intermediate buffer layer, a surface layer, a wear-resistant and anti-slip layer, and a strong anti-slip layer. The added intermediate buffer layer can play a shock-absorbing role. When items are placed on the surface of the cover and the vehicle encounters bumps, the intermediate buffer layer can protect the items. The wear-resistant and anti-slip layer on the top can increase the friction when items are placed, improving the stability of the items. The strong anti-slip layer makes the cover more stable and secure when placed inside the trunk.

[0014] 2. When in use, this utility model provides a shock-absorbing and anti-slip car spare tire cover, which includes a structural support layer, an intermediate buffer layer, a surface layer, a wear-resistant and anti-slip layer, and a strong anti-slip layer. The surface layer and the wear-resistant and anti-slip layer are an integral structure, and the surface layer can be removed from the surface of the intermediate buffer layer, making it easy to remove the surface layer for cleaning.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a shock-absorbing and anti-slip car spare tire cover is provided, including a structural support layer 1, an intermediate buffer layer 2 fixedly connected to the upper surface of the structural support layer 1, a removable surface layer 3 fixed to the upper surface of the intermediate buffer layer 2, a wear-resistant and anti-slip layer 4 provided on the upper surface of the surface layer 3, and a strong anti-slip layer 5 fixed to the lower surface of the structural support layer 1. The strong anti-slip layer 5 is arranged along the side of the lower surface of the structural support layer 1 and is in a ring shape.

[0024] In this embodiment, the structural support layer 1 is made of PP (polypropylene) material, and its structure is honeycomb. By using PP (polypropylene) material instead of traditional MDF, the structural support layer 1 has good support strength, while also achieving lightweighting and reducing the weight of the overall cover plate.

[0025] The strong anti-slip layer 5 and the structural support layer 1, as well as the intermediate buffer layer 2 and the structural support layer 1, are all fixed together with adhesive.

[0026] In this embodiment, the intermediate buffer layer 2 is made of high-density EVA foam, which has high elasticity and excellent shock absorption performance, effectively absorbing vibrations and noise during vehicle operation. Its closed-cell structure is moisture-proof and corrosion-resistant, easy to process and mold, and has a moderate cost.

[0027] The strong anti-slip layer 5 uses magnetic sheet material.

[0028] In this embodiment, the strong anti-slip layer 5 is made of magnetic sheet material or silicone anti-slip particles, so that when the cover is placed inside the trunk, the strong anti-slip layer 5 is in contact with the iron frame on the side of the spare tire. The strong anti-slip layer 5 can increase the friction when the cover is placed, thereby improving the stability of the cover when it is placed and avoiding the cover from shifting due to large bumps.

[0029] The wear-resistant and anti-slip layer 4 is a coating.

[0030] In this embodiment, the surface layer 3 is made of needle-punched nonwoven fabric, PVC leather, or fiber fabric, and the wear-resistant and anti-slip layer 4 is made of TPU (thermoplastic polyurethane). The wear-resistant and anti-slip layer 4 is fixed to the surface of the surface layer 3 by coating, and the specific structure of the wear-resistant and anti-slip layer 4 adopts a 3D three-dimensional texture. The wear-resistant and anti-slip layer 4 can increase the friction of items placed on the surface of the cover plate and prevent items from sliding.

[0031] The structural support layer 1 has multiple screw holes 6 on its side. The intermediate buffer layer 2 and the surface layer 3 each have multiple through holes 7 corresponding to the positions of the screw holes 6. Bolts 8 are matched with the multiple screw holes 6. A knob is fixed to the top of the bolt 8, and the bottom of the bolt 8 passes through the through hole 7 and is screwed into the screw hole 6.

[0032] In this embodiment, there are at least four screw holes 6. After the surface layer 3 is placed on the surface of the intermediate buffer layer 2, the through holes 7 on the surface layer 3 coincide with the through holes 7 on the intermediate buffer layer 2. Then, the bolts 8 are passed through the through holes 7 and screwed into the screw holes 6. The knob is located on the upper surface of the surface layer 3 to fix the surface layer 3. When it is necessary to remove the surface layer 3 for cleaning, each bolt 8 is unscrewed in turn to remove the surface layer 3 from the upper surface of the intermediate buffer layer 2.

[0033] Multiple Velcro straps 9 are fixed to the upper side of the intermediate buffer layer 2 and the lower side of the surface layer 3. The Velcro straps 9 on the intermediate buffer layer 2 and the surface layer 3 are hook side and hook side, respectively.

[0034] In this embodiment, in addition to fixing the surface layer 3 with bolts 8, it is also attached to the upper surface of the intermediate buffer layer 2 with Velcro 9 on its lower surface. The Velcro 9 further fixes the surface layer 3 to the upper surface of the intermediate buffer layer 2, preventing the sides of the surface layer 3 from peeling off. When actually removing the surface layer 3, first unscrew the bolts 8, then peel the surface layer 3 off the surface of the intermediate buffer layer 2.

[0035] A handle 10 is fixed to the upper surface of the surface layer 3. The handle 10 facilitates pulling the cover to open upwards inside the trunk.

[0036] Working Principle: During production, the cover plate is assembled by adhesive bonding, with the intermediate buffer layer 2 fixed to the upper surface of the structural support layer 1. Similarly, the strong anti-slip layer 5 is fixed to the lower surface of the structural support layer 1 using adhesive bonding. The surface layer 3 is then attached to the upper surface of the intermediate buffer layer 2, first secured with Velcro 9, and then fixed with bolts 8. When items are placed on the surface layer 3, they actually contact the wear-resistant anti-slip layer 4, increasing friction and preventing slippage. The structural support layer 1 is attached to the metal frame on the side of the spare tire in the trunk via the strong anti-slip layer 5, increasing friction and improving stability. The intermediate buffer layer 2 acts as a cushioning and shock absorber. To clean the surface layer 3, simply unscrew the bolts 8 and peel the surface layer 3 off the upper surface of the intermediate buffer layer 2.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
