[0035] As shown in FIG. 1, the automobile seat includes a seat foam 200 and an automobile seat ventilation structure 100, and the automobile seat 200 is provided with a mounting area 201, and the automobile seat ventilation structure 100 is installed on the mounting area 201. Figures 1-3 As shown in FIG. 1, the automobile seat includes a seat foam 200 and an automobile seat ventilation structure 100, and the automobile seat 200 is provided with a mounting area 201, and the automobile seat ventilation structure 100 is installed on the mounting area 201.

[0036] The sealing layer 13 can be a non-woven adhesive layer, which has a sealing effect and can prevent air leakage of the air blown or sucked by the fan 30. The air guide layer 20 is specifically a 3D spacer fabric, which has a certain thickness and hardness, good elasticity and support, and forms a plurality of pores when woven to form a plurality of air paths to achieve the air guide effect. The air distribution layer 14 is provided with a first air guide hole 141, which is arranged correspondingly to the air vent hole 202 of the seat foam 200.

[0042] In another specific embodiment, as shown in Figures 4-5As shown, two fixing positions 12 are arranged around the mounting area 11, and the two fixing positions 12 are arranged on the left and right sides of the mounting area 11. In other embodiments, the two fixing positions 12 can also be arranged at other positions around the mounting area 11, for example, one of the fixing positions 12 is arranged above the mounting area 11, and the other fixing position 12 is arranged below the mounting area 11, or one of the fixing positions 12 is arranged above the mounting area 11, and the other fixing position 12 is arranged on the right side of the mounting area 11.

[0043] In another specific embodiment, a plurality of fixing positions 12 are arranged around the mounting area 11, and at least one fixing position 12 is arranged above the mounting area 11. For example, Figures 6-7 As shown, three fixing positions 12 are arranged around the mounting area 11, and the three fixing positions 12 are arranged above, on the left side and on the right side of the mounting area 11, respectively, and the three fixing positions 12 form a triangle along the circumferential line of the mounting area 11. In other embodiments, the three fixing positions 12 can also be arranged at other positions around the mounting area 11, for example, two of the fixing positions 12 are arranged above the mounting area 11, and the other fixing position 12 is arranged below the mounting area 11.

[0044] In another specific embodiment, as shown, Figures 8-9 As shown, four fixing positions 12 are arranged around the mounting area 11, and two of the fixing positions 12 are arranged on the left side of the mounting area 11, and the other two fixing positions 12 are arranged on the right side of the mounting area 11, and the four fixing positions 12 form a quadrilateral along the circumferential line of the mounting area 11. In other embodiments, the four fixing positions 12 can also be arranged at other positions around the mounting area 11, for example, one of the fixing positions 12 is arranged on the left side of the mounting area 11, and the other fixing position 12 is arranged on the right side of the mounting area 11, the third fixing position 12 is arranged above the mounting area 11, and the last fixing position 12 is arranged below the mounting area 11.
