Several sheets are welded to form several inflatable units, and the connecting part on the sheet material and the connecting part realize the connection and communication between the several inflatable units in the same processing and forming direction, thereby ensuring the simplicity of the inflatable support structure while facilitating the design of automated mass production.

The four inflatable units cooperate with the setting of the connecting part to realize the selective arrangement of different air path connections, thereby achieving different soft and hard adjustment effects in different regions, thereby improving the comfort of the support effect.

[0012] The utility model is further configured as follows: the communication portion comprises a first communication portion and a second communication portion, the first communication portion is formed at the first connecting portion, and the second communication portion is formed at the second connecting portion.

[0054] The second connecting portion 32 can be selectively opened on the second connecting portion 22 by designing the gas path. In this embodiment, each second connecting portion 22 is formed with the second connecting portion 32. The first connecting portion 21, the second connecting portion 22, the first connecting portion 31 and the second connecting portion 32 are all formed on the surface of the sheet 4. The processing direction of the inflatable unit 1 formed by high-frequency welding is the same as the processing direction of connecting and connecting several inflatable units 1, so that the overall operation direction of the inflatable support body during the molding process is consistent, thereby facilitating the automated mass production design of the inflatable support body.

[0056] Embodiment 2, an inflatable support, such as Figure 6 , 7As shown, it includes a number of inflatable units 1 with the same length direction and supporting direction, and a connection part 2 connecting adjacent inflatable units 1 and a connecting part 3 connecting adjacent inflatable units 1 are formed on adjacent surfaces of the inflatable units 1. The difference from Example 1 is that in this embodiment, the first connection part 21 is the sheet surface of the sheet 4 body, the second connection part 22 can be a ventilation quick connector preformed on the sheet 4, and the second connecting part 32 is an air hole opened at the connection of the ventilation quick connector.

The first sheet 41 and the second sheet 42 are high-frequency welded to form a first edge unit group 51, and the fourth sheet 44 and the third sheet 43 are high-frequency welded to form a second edge unit group 52; combined Fig.10 , Fig.14 The second sheet 42 is high-frequency welded with the second sheet 42 to form a first internal unit group 61; Fig.15 , 16 , the third sheet 43 and the third sheet 43 form a second internal unit group 62. In this embodiment, there are 24 sheets 4 in total, and the number of the first edge unit group 51 and the second edge unit group 52 formed is 1 each, and the number of the first internal unit group 61 and the second internal unit group 62 are 5 each.

The second connecting portion 32 is two circular holes spaced apart on the second connection portion 22. A second connection portion 22 is formed on the sheet 4 for every two first connection portions 21, that is, it is formed for every other inflatable unit 1. The second connection portion 22 formed on the second sheet 42 is located at a molding position on the inflatable unit 1 adjacent to the first connection portion 21 on one side, and the second connection portion 22 formed on the third sheet 43 is located at a molding position on the inflatable unit 1 adjacent to the first connection portion 21 on the other side, and when the first internal unit group 61 and the second internal unit group 62 are connected by welding through the second connection portion 22, the second connection portion 22 on the second sheet 42 and the second connection portion 22 on the third sheet 43 are kept horizontally aligned, and the connection and staggered arrangement of adjacent inflatable units 1 in the second direction after connection are realized by the staggered second connection portions 22. In this embodiment, the third inflatable unit 13 and the fourth inflatable unit 14 of the first edge unit group 51, the second edge unit group 52, the first internal unit group 61, and the second internal unit group 62 are all the same size, and are the same size as the first inflatable unit 11 of the first edge unit group and the second inflatable unit 12 of the first internal unit group 61; and the width of the complementary unit 111 of the second edge unit group 52 and the first internal unit group 61 is smaller than the second inflatable unit 12, so that the short side surface of the inflatable support body formed by the staggered arrangement of several inflatable units 1 is a flat side surface, ensuring the squareness and beauty of the overall structure of the inflatable support body.

When assembling the inflatable bed, the inner lining cover 71 is put on the inflatable support body 7 after the inflatable support body 7 is inflated, so as to improve its integrity and facilitate assembly with the comfort layer 8 in the bed sheet 9.

[0061] The working principle and beneficial effects of the utility model are as follows: multiple vertically supported inflatable units 1 are integrally formed and the air paths are interconnected. When the pressure applied by the human body on the support surface changes, the airflow in the inflatable unit 1 at the support position flows to the inflatable units 1 at other positions through the connecting portion 3, thereby achieving a multi-point support and comfort effect. The connecting portion 2 and the connecting portion 3 on the inflatable unit 1 are both formed on the adjacent surfaces of the inflatable unit 1, so that when the inflatable support body 7 is formed, the forming direction of the connecting portion 2 and the connecting portion 3 is consistent with the forming direction of several inflatable units 1, and the connecting portion 2 and the connecting portion 3 can be formed in the same direction as several inflatable units 1, thereby ensuring the simple structure of the inflatable support body 7 while facilitating the design of automated mass production. The inflatable support body 7 is assembled into an inflatable mattress, which cooperates with the comfort layer 8 to provide comfortable support to the human body and enhance the user experience of the inflatable mattress.
