Description

Technical Field

[0001] The utility model relates to the field of air cushions, and particularly to a TPU air cushion. Background Art

[0002] In many application scenarios such as outdoor exploration, sports fitness, and emergency rescue, the air cushion, as a key equipment for human support and protection, its design and performance directly affect the user experience and safety. However, the traditional air cushion design often adopts a whole-piece inflatable structure. This design not only has problems of material waste and excessive weight, but also has low inflation efficiency and long inflation time due to a large amount of inflation. These limitations not only restrict the portability and use efficiency of the air cushion, but also affect the user experience and safety, and urgently need to be improved and optimized through innovative design. Summary of the Utility Model

[0003] In view of this, the utility model provides a TPU air cushion. The inflatable frame serves as the core support structure of the air cushion, and the outer cover on the outer periphery of the inflatable frame provides a protective function. The inflatable cross tube serves as a key support structure inside the air cushion, which not only increases the stability of the air cushion, but also reduces the weight, lowers the cost, improves the inflation efficiency, and is more portable for storage.

[0004] The purpose of the utility model is achieved through the following technical solutions:

The inflatable cross tube is communicated with the inflatable frame, and the inflatable cross tube is located inside the outer cover.

[0006] The inflatable frame serves as the core support structure of the air cushion, which not only bears the human weight, but also ensures the stability and safety of the air cushion during use through its unique structural design. The outer cover covering the outer periphery of the inflatable frame not only provides additional protection for the air cushion, but also improves the user comfort and experience through its soft touch and breathability. The inflatable cross tube serves as a key support structure inside the air cushion, which increases the stability of the air cushion, disperses the pressure of the human body on the air cushion through its unique layout, and improves the comfort and support of the air cushion. The setting of the inflatable cross tube not only increases the stability of the air cushion, but also reduces the weight, lowers the cost, improves the inflation efficiency, and is more portable for storage. The reduction in weight makes carrying and handling easier and more convenient. In outdoor exploration and camping activities, the lightweight air cushion design can significantly reduce the burden on the backpack, improve the traveling speed and comfort, and bring a more relaxed and comfortable carrying experience for outdoor enthusiasts. In addition, the communication design between the inflatable cross tube and the inflatable frame not only simplifies the inflation process of the air cushion, but also can achieve the balance of the overall inflation state of the air cushion through the inflation of the inflatable cross tube, improving the stability and use experience of the air cushion.

[0007] This TPU air mattress can be used alone as an outdoor camping mat, or as the bottom mat of a rooftop tent, or the bottom mat of a water tent, etc. Through its inflatable frame, the outer cover covering it, and the ingeniously designed inflatable cross tubes, it not only significantly improves the comfort, stability and durability of the air mattress, but also realizes the optimization of the air mattress structure and the upgrade of the user experience, bringing an unprecedented comfortable and safe experience to outdoor and sports enthusiasts. These breakthroughs in innovative designs not only reflect the comprehensive consideration of structural stability, comfort experience and durability in modern air mattress design, but also indicate the development trend of air mattress products towards higher-end, more comfortable and more durable. Through continuous innovation and optimization, future air mattress products will be able to better meet the market and consumers' demands for high-quality, high-comfort and durable products, promote the entire industry to develop towards higher-end, more comfortable and more durable, provide a more comfortable and safe user experience for outdoor and sports enthusiasts, and inject new vitality and inspiration into the field of modern outdoor and sports products.
