This design not only ensures the stability of the structure, but also gives the tent mattress better support and stability, especially in outdoor camping environments, it can effectively resist the pressure and influence of the external environment;

[0042] The tent mattress composed of the air cushion bed body 1, the bag frame body 2, the air guide hose 3, and the pressure relief component 4, when being inflated, the gas is pumped to the air guide hose 3 by the air pump 17, and then the air guide hose 3 delivers the gas to the bag frame body 2. After the bag frame body 2 is saturated, the excess gas will enter the air cushion bed body 1 through the pressure relief component 4. In other words, the tent mattress first fills the upper bag frame body 2 with gas, and then inflates the air cushion bed body 1. This design enables the bag frame body 2 to first obtain sufficient supporting force to ensure the overall shape and stability of the tent mattress. Subsequently, after the air cushion bed body 1 is replenished with gas, the comfort and adaptability of the mattress can be further increased. In addition, due to the existence of the bag frame body 1, the tent mattress can maintain overall stability while also being able to adjust the softness and hardness of the mattress by the inflation amount of the air cushion bed body 1 to meet the sleeping needs of different people.

Air guide holes 13 are reserved at both ends of each drawstring 12 (the air guide holes 13 reserved at both ends of each drawstring 12 are conducive to the uniform distribution and flow of gas, ensuring that the mattress can expand quickly and evenly when inflated, thereby improving the comfort of use). The upper bag membrane 14 and the lower bag membrane The opposite end surfaces of 15 are all arranged in a wave shape (this design increases the support area of ​​the mattress, so that it can better fit the human body curve and improve sleeping comfort. At the same time, the wave shape also helps the mattress to better disperse pressure when under force and reduce body fatigue), and the junctions of the side bag membrane 11, the upper bag membrane 14 and the side bag membrane 11, the lower bag membrane 15 are connected with stirrups 16 (significantly enhancing the strength and stability of the edge of the mattress to prevent the mattress from deforming or collapsing during use), and the surface of the side bag membrane 11 and one side of the air pump 17 are embedded with a No. 1 exhaust valve 18 (the No. 1 exhaust valve 18 embedded in the surface of the side bag membrane 11 is convenient for users to adjust the inflation volume of the mattress as needed to achieve the best sleeping effect. At the same time, the design of the exhaust valve also allows the mattress to be quickly deflated when not in use, which is convenient for storage and carrying).

This design not only enhances the overall stability of the bag frame body 2, but also forms a solid support frame above the mattress. The arch structure can effectively resist external pressure, especially in environments such as outdoor camping, and can provide additional protection). The third bag column 23 is connected to the highest point of the arch structure of the first bag column 21 and the second bag column 22 (the third bag column 23 is connected to the highest point of the arch structure of the first bag column 21 and the second bag column 22. This design further enhances the structural strength of the bag frame body 2. The third bag column 23 not only serves as the connection point of two parallel bag columns, but also can provide additional support in the vertical direction, making the entire bag frame body more stable). The first bladder column 21, the second bladder column 22, and the third bladder column 23 are connected (the first bladder column 21, the second bladder column 22 and the third bladder column 23 are connected. This design allows the gas to be quickly and evenly distributed throughout the entire bladder frame during inflation. This ensures that the bladder frame can quickly reach a predetermined shape and strength after inflation, improving the convenience and efficiency of use), the air guide hose 3 is connected to one end of the first bladder column 21, the pressure relief component 4 is installed at one end of the second bladder column 22, and a No. 2 exhaust valve 24 is embedded on the surface of the first bladder column 21 (the air guide hose 3 is connected to one end of the first bladder column 21, which is convenient for introducing gas from the inflation pump 17. The pressure relief component 4 is installed at one end of the second bladder column 22.
