Description

Technical Field

[0001] This utility model relates to the field of protective pad technology, specifically a layered buffer silicone protective pad. Background Technology

[0002] In the field of protective gasket technology, silicone is widely used for cushioning and protection in electronic devices, precision instruments, and household goods due to its excellent elasticity, aging resistance, and chemical stability. However, most silicone protective gaskets on the market today use a single material or a simple composite structure design, which reveals many performance shortcomings in actual use and makes it difficult to meet the high-efficiency protection needs in various scenarios. In terms of cushioning performance, existing protective pads generally suffer from a single cushioning system. Most products rely solely on solid silicone or single-density foamed silicone for cushioning, failing to provide tiered responses to impacts of varying intensities. While solid silicone offers some support, its high hardness limits its impact absorption capacity. When subjected to strong impacts, energy is easily transferred directly to the protected object, leading to shell damage or internal component damage. While single-foamed silicone can absorb some impact energy, its insufficient structural strength makes it prone to excessive deformation under pressure. Over time, its elastic recovery capacity decreases, failing to provide stable support for the protected object. This is particularly problematic in scenarios requiring high precision, such as the transport of precision instruments, where excessive cushioning can cause equipment displacement. Therefore, a layered cushioning silicone protective pad is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a layered buffer silicone protective pad, which solves the problem of poor buffering effect of protective pads.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a layered buffer silicone protective pad, comprising a protective pad body, wherein anti-slip protrusions are fixedly installed on the inner surface of the protective pad body; The protective pad body is equipped with a buffer mechanism, which includes anti-slip texture, solid silicone pad and foamed silicone pad. The solid silicone gasket is bonded to the lower surface of the protective gasket body.

[0005] Preferably, the anti-slip texture is formed on the upper surface of the protective pad body, and the anti-slip texture surface is arranged in a stripe pattern.

[0006] Preferably, the foamed silicone pad is bonded to the lower surface of the solid silicone pad, and the foamed silicone pad has triangular air holes inside.

[0007] Preferably, the buffer mechanism further includes a foam composite gasket, which is bonded to the lower surface of the foamed silicone gasket, and the foam composite gasket has stacked rectangular air holes inside.

[0008] Preferably, the anti-slip textured surface is arranged in a grid pattern.

[0009] Compared with the prior art, the present invention provides a layered buffer silicone protective pad, which has the following beneficial effects: 1. This layered buffer silicone protective pad constructs a three-level buffer system through the layered combination of solid silicone pads, foamed silicone pads, and foam composite pads. The solid silicone pads bear external forces and transmit them evenly, avoiding over-buffering. The honeycomb-shaped pores of the foamed silicone pads compress and deform, absorbing most of the impact energy. The bubble structure of the foam composite pads attenuates residual vibrations, serving as the last line of defense. This layered design can cope with impacts of different intensities. Compared with single-material pads, it can more efficiently and comprehensively disperse external forces, significantly reducing the risk of damage to the protected object, and is suitable for various scenarios such as transportation and daily protection.

[0010] 2. This layered buffer silicone protective pad features anti-slip textures on its upper surface, increasing friction resistance with the object being placed on it. The mesh pattern, in particular, prevents sliding in both directions. Anti-slip protrusions are fixed to the inner surface of the pad, physically locking into gaps in the protected object and enhancing the fit between the pad and the protective carrier. Together, these features solve two major problems: the object sliding on the pad and the pad shifting itself. For example, during the transport of electronic equipment, this design can both secure the equipment and ensure that the pad does not shift within the packaging box, guaranteeing accurate protective positioning.

[0013] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-3 This utility model provides a new technical solution: a layered buffer silicone protective pad, including a protective pad body 1, and anti-slip protrusions 3 are fixedly installed on the inner surface of the protective pad body 1. The protective pad body 1 is provided with a buffer mechanism, which includes anti-slip texture 2, solid silicone pad 4 and foamed silicone pad 5. Among them, the solid silicone gasket 4 is bonded to the lower surface of the protective gasket body 1.

[0015] Furthermore, anti-slip texture 2 is formed on the upper surface of the protective pad body 1, and the surface of the anti-slip texture 2 is striped.

[0016] Furthermore, the foamed silicone gasket 5 is bonded to the lower surface of the solid silicone gasket 4, and the foamed silicone gasket 5 has triangular air holes inside.

[0017] Furthermore, the cushioning mechanism also includes a foam composite gasket 6, which is bonded to the lower surface of the foamed silicone gasket 5. The foam composite gasket 6 has stacked rectangular air holes inside.

[0018] Furthermore, the anti-slip texture 2 is arranged in a grid pattern on the surface; Structural Explanation: Protective Gasket Body 1: The protective gasket body 1 is the basic framework and core support component of the entire protective gasket. It integrates all functional components. The anti-slip protrusions 3 fixed on the inner surface can enhance the fit with the protected object and prevent the gasket from shifting. Its upper and lower surfaces are respectively connected to the anti-slip texture 2 and the solid silicone gasket 4, which not only serve as the connecting carrier for each component, but also provide initial protection and shape support for the whole through its own structure. It is the key to ensuring the integrity and basic function of the gasket.

[0019] Anti-slip texture 2: The anti-slip texture 2 has a crisscross grid structure, which forms friction resistance in both the horizontal and vertical directions. In scenarios with multi-directional forces, the grid-like lines can block sliding in two directions at the same time, preventing items from shifting or becoming misaligned on the pad. Combined with the layered cushioning mechanism, it achieves dual protection of anti-slip and cushioning.

[0020] Anti-slip protrusion 3: The anti-slip protrusion 3 is fixedly installed on the inner surface of the protective pad body 1. It is an anti-slip design for the contact surface between the pad and the protected object. The protrusion structure can be embedded or fit into the tiny gaps on the surface of the protected object to form a physical jamming effect, further enhancing the connection stability between the pad and the protected object. Even under slight external vibration or displacement force, the overall slippage of the pad can be reduced through the interlocking action of the protrusion, ensuring the accuracy of the protective position.

[0021] Solid silicone pad 4: The solid silicone pad 4 is connected to the lower surface of the protective pad body 1 and is the middle load-bearing layer in the layered buffer structure. It is made of solid silicone material, which has a certain degree of hardness and elasticity. It can not only bear the pressure from the body 1 and evenly transmit it to the foamed silicone pad 5 below, but also provide basic buffering by relying on the elastic deformation of its own material. At the same time, the solid structure can avoid insufficient support caused by excessive buffering, and provide a stable force foundation for the overall buffer system.

[0022] Foamed silicone pad 5: Foamed silicone pad 5 is connected to the lower surface of solid silicone pad 4 and is the core reinforcing layer of layered buffer. When subjected to external impact or pressure, the pores will absorb and disperse energy through compression deformation, greatly reducing the impact of the impact on the protected object. Compared with solid silicone, honeycomb pores can achieve shock absorption and buffering more efficiently, while maintaining the lightweight of the material and improving the protective performance and user comfort of the pad.

[0023] Foam composite gasket 6: Foam composite gasket 6 is connected to the lower surface of foamed silicone gasket 5 and is the outermost buffer layer of the entire protective gasket. Its internal bubble structure gives it the characteristics of being soft and highly elastic, and it can serve as the last line of defense against impact. After the impact force passes through the first two layers of buffer, the foam composite gasket 6 can further attenuate the remaining vibration and impact through the further compression and rebound of the bubbles. At the same time, its soft material can reduce the friction and hard collision between the gasket and the external contact surface, improving the softness and comprehensiveness of the overall protection.

[0024] When an object presses or impacts the upper surface of the layered buffer silicone protective pad 1, the body 1 transmits the external force to the solid silicone pad 4 on the lower surface. The solid silicone pad 4 first undergoes slight compression deformation, which transmits the force to the lower layer of foamed silicone pad 5. Under pressure, its honeycomb pores are squeezed and contracted, absorbing some energy. The force that is not completely absorbed continues to be transmitted to the bottom layer of foam composite pad 6, where the internal air bubbles are compressed, further consuming the impact force. When the external pressure is removed, the honeycomb pores of the foamed silicone pad 5 and the air bubbles of the foam composite pad 6 recover their original shape due to their own elasticity, causing the solid silicone pad 4 and the protective pad body 1 to reset in sequence. The entire device returns to its initial state, waiting for the next external force.

[0025] Example 1: Mesh-like anti-slip texture in the cushioning scenario of electronic equipment transportation like Figure 2 As shown: During express delivery, electronic devices such as laptops and tablets need to be protected with cushioning pads to prevent the devices from shifting, the outer shell from being scratched, or the internal components from being damaged due to bumps and collisions. The layered cushioning silicone protective pads with grid-like anti-slip texture 2 are cut to the size of the device and attached to the inner wall of the transport packaging box to achieve double fixation between the device and the packaging box. The mesh-like anti-slip texture 2 is composed of crisscrossing raised lines, forming dense square grid units. When the electronic device is placed in the packaging box, the device shell makes full contact with the mesh texture. Each raised node of the grid unit can form point contact friction with the device surface. When the transport vehicle brakes suddenly, turns, or bumps, the device will have a tendency to move laterally and longitudinally. The crisscrossing lines of the mesh texture can simultaneously resist the force in both directions. The lateral lines restrict the device from sliding left and right, and the longitudinal lines restrict the device from moving forward and backward, forming a two-way anti-slip lock. In addition, the gaps between the grids can accommodate bubble wrap fragments inside the packaging box. Alternatively, cushioning cotton can be used to further enhance the fit between the equipment and the pad, preventing the equipment from shaking within the gap. The three-dimensional structure of the grid pattern has a more comprehensive force distribution capability than the striped pattern, and can cope with complex multi-directional impacts during transportation. At the same time, the air circulation gaps formed by the grid protrusions can provide ventilation when the equipment generates slight moisture due to temperature changes, preventing the equipment shell from getting damp. This pattern design enables the protective pad to achieve both anti-slip fixation and, together with the lower cushioning mechanism, the foamed silicone pad 5 and the foam composite pad 6 form a dual protection of anti-slip and cushioning, significantly reducing the damage rate of electronic equipment during transportation.
