[0051] The fixing portion 7 is further provided with a through portion 10 and at least one first connecting portion 11 . The first connecting portion 11 is used to mount a fan 12 . The through portion 10 passes through the fixing portion 7 and is arranged corresponding to the air outlet position of the fan 12 .

[0052] The size of the fixing portion 7 can be set to be much larger than the radial size of the supporting portion 8, so that the fixing portion 7 has a larger contact area with the sealing layer 3, and the connection between the fixing portion 7 and the sealing layer 3 is more secure. Based on the larger size of the fixing portion 7, a through portion 10 and at least one first connecting portion 11 are provided on the fixing portion 7. Specifically, the first connecting portion 11 is a through hole passing through the fixing portion 7. The fan 12 can be fixed to the first connecting portion 11 by passing through the sealing layer 3 through a rubber rivet, and then the fan 12 is fixed to the side of the sealing layer 3 away from the supporting layer 4, so that the fixing portion 7 plays the role of an adapter used when connecting the traditional fan 12, thereby eliminating the need for the adapter. Moreover, since the fixing portion 7 is installed between the sealing layer 3 and the supporting layer 4, the fan 12 can be effectively prevented from falling off due to the falling off of the fixing portion 7; the through portion 10 is a through hole passing through the fixing portion 7. When the fan 12 is installed, the through portion 10 corresponds to the air outlet position of the fan 12. Correspondingly, a ventilation opening is opened on the sealing layer 3 between the through portion 10 and the fan 12, thereby achieving conduction between the air outlet of the fan 12 and the supporting layer 4.

[0053] Further, at least one clamping portion 13 is provided on the fixing portion 7. The clamping portion 13 penetrates through the sealing layer 3, and a clamping groove 14 for clamping with the seat back spring 15 is provided on one side of the clamping portion 13.

[0054] Specifically, the clamping portion 13 is provided on the side of the fixing portion 7 close to the sealing layer 3. The clamping portion 13 penetrates through the sealing layer 3, and a clamping groove 14 is formed on the side wall of the clamping portion 13. During installation, in addition to bonding the fixing portion 7 to the sealing layer 3, the clamping portion 13 can be clamped to the seat back spring 15 through the clamping groove 14, so as to further fix the fixing portion 7, further prevent the fixing portion 7 from falling off, and at the same time prevent the airbag 2 from falling off the seat foam 1.

[0055] Further, a plurality of first connecting portions 11 and a plurality of clamping portions 13 are provided. The plurality of first connecting portions 11 are arranged along the circumferential direction of the penetrating portion 10, and the plurality of clamping portions 13 are provided on the side of the plurality of first connecting portions 11 away from the penetrating portion 10.

[0056] Specifically, to further improve the connection strength between the fixing portion 7 and the fan 12, as well as the connection strength between the fixing portion 7 and the seat back spring 15, a plurality of first connecting portions 11 and clamping portions 13 can be provided. Refer to Figure 5 and Figure 6 , in this embodiment, four first connecting portions 11 and four clamping portions 13 are provided. The four first connecting portions 11 are arranged evenly along the circumferential direction of the penetrating portion 10. The four first connecting portions 11 correspond to a plurality of installation positions on the circumferential side of the fan 12. During installation, they are connected one by one through rubber rivets, so that the fan 12 is fixed more firmly; refer to the figure. In this embodiment, a plurality of clamping portions 13 are provided. The plurality of clamping portions 13 are arranged along the circumferential direction of the penetrating portion 10 and are provided on the side of the first connecting portions 11 away from the penetrating portion 10. By providing a plurality of clamping portions 13, the fixing portion 7 can be connected to different positions of the seat back spring 15 respectively, further preventing the fixing portion 7 from falling off.

[0057] Embodiment 3

[0058] Refer to Figure 10 and Figure 11 , this embodiment provides another fixing structure. The same content as that in Embodiment 2 will not be described in detail. The differences are as follows:

[0059] A second connecting portion is provided on the fixing portion 7. The second connecting portion is used for installing the seat massage controller 16, and the installation portion 9 is also used for fixing the air pipe 17 led out by the seat massage controller 16.

[0060] Specifically, for a seat with a massage function, a seat massage controller 16 for controlling the air passage between the air pump 21 and the inflatable bag can also be installed inside the seat. By providing a second connecting portion on the fixing portion 7, the seat massage controller 16 can be fixed in the same way as the fan 12. The seat massage controller 16 is connected to different inflatable bags by leading out a plurality of air pipes 17. When the air pipes 17 are not fixed, they will collide with the internal structure of the seat during inflation and deflation, generating abnormal noises. The air pipes 17 can also be fixed by binding them to the installation portion 9.

[0061] Embodiment 4

[0062] Reference Figure 12 and Figure 13 In this embodiment, another fixing structure is provided. The same content as in Embodiment 1 or Embodiment 2 or Embodiment 3 will not be described in detail. The difference is that the support portion 8 is hollow inside and has an opening on one side wall. The installation portion 9 is provided at the end of the support portion 8 away from the fixing portion 7 and penetrates the end wall of the support portion 8. The installation portion 9 is spaced from the opening on the side wall of the support portion 8 by a part of the support portion 8.
