[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] like Figures 1 to 16 As shown, the present embodiment provides an air suction type automobile seat back ventilation structure, comprising an air bag 1, a bracket 2 and a fan 4; a plurality of ventilation holes 15 are arranged on one side of the air bag 1, and an air inlet hole 17 is arranged on the other side of the air bag 1, and the plurality of ventilation holes 15 are connected with the air inlet hole 17 inside the air bag 1; the fan 4 is arranged on the other side of the air bag 1 through the bracket 2, and the air inlet 42 of the fan 4 corresponds to the position of the air inlet hole 17; the air bag 1 is used to be arranged between the frame and the foaming structure of the seat.

[0042] In this specific embodiment, a seal 3 is provided between the bracket 2 and the air inlet 42 of the fan 4. The seal 3 can be specifically made of a ring-shaped high-elasticity closed-cell sponge, which is bonded to the periphery of the air inlet 42 of the fan 4 by double-sided adhesive. When the fan 4 and the bracket 2 are connected, the seal 3 is compressed to fill the gap between the fan 4 and the bracket 2. The closed-cell sponge can play a sealing role between the air inlet 42 of the fan 4 and the bracket 2. At the same time, it can prevent the abnormal sound caused by the collision between the fan 4 and the bracket 2 due to the bumps during the driving of the car.

[0043] The air bag 1, the bracket 2 and the fan 4 are connected by a glue nail 5, one end of the glue nail 5 is provided with a bracket fixing position 53, the middle of the glue nail 5 is provided with a fan fixing position 52, and the other end of the glue nail 5 is a handle 51. The bracket fixing position 53 is used to match the ventilation fixing hole 16 on the air bag 1, and the fan fixing position 52 corresponds to the mounting holes around the fan 4. There are four fixing holes on the fan 4. The glue nail 5 is first fixed on the bracket 2, and then the handle 51 is passed through the four fixing holes of the fan 4 and tightened to fix the fan 4 on the bracket 2.

[0044] The air bag 1 includes a first PU film 11, a ventilation net 12, a second PU film 13 and a felt layer 14 arranged in sequence, and the edges of the first PU film 11, the ventilation net 12, the second PU film 13 and the felt layer 14 are connected by welding. The front of the backrest and the air bag 1 are fixed together by ultrasonic welding. The ventilation net 12 is made of a high air permeability material that has both strength and allows air to pass through. In this specific embodiment, the ventilation net 12 is made of a sandwich net.

[0045] The air bag 1 is placed between the seat foam and the frame, and the side close to the frame is a felt layer 14, the felt layer 14 and the bracket 2 are fixed by ultrasonic welding, and the opening of the air inlet 42 of the fan 4 is close to the side of the frame. A ventilation hole 15 and a system fixing hole 21 are opened on the side close to the foam, and the ventilation system is fixed on the foam through the system fixing hole 21.

[0046] When the fan 4 is working, air enters the ventilation bag 1 through the ventilation holes 15, then enters from the air inlet 42 of the fan 4, and flows out from the air outlet 43, thereby achieving an air suction effect of the seat.

[0047] The bracket 2 is a square plate structure, which is made of ABS plastic injection molding. A round hole is set in the middle of the bracket 2 as a wind hole. Four through positioning holes are set around the bracket 2. The positioning holes correspond to the positions of the ventilation fixing holes 16 on the air bag 1, which are used to fix the ventilation system on the seat back. The whole chair fixing method of the ventilation system is as follows Fig.15 and 16 As shown, four fixing columns are pre-buried on the backrest foam, corresponding to the system fixing holes 21 of the ventilation system, so as to fix the ventilation system. The plastic welding surface 22 of the bracket 2 is used to connect with the sealing member 3.

[0048] Four buckles 41 are arranged around the air inlet 42 of the fan 4 . The buckles 41 are of a barbed hook structure and are used to connect with the air holes of the bracket 2 .

[0049] The diameters of the multiple ventilation holes 15 on one side of the air bag 1 increase as the distance from the air inlet 42 of the fan 4 increases. Fig.14As shown, the ventilation holes R1-R7 become larger in sequence according to the distance from the air inlet 42 of the fan 4. For example, R1 is closest to the air outlet, and the diameter of the air hole of R1 is a, R2 is a+0.5b, R3 is a+1b, R4 is a+1.5b, and so on.

[0050] The farther away from the air inlet 42, the worse the air intake effect. By gradually increasing the diameter of the air holes, the ventilation volume is increased, so that the ventilation effects of the ventilation holes 15 at different distances are more uniform.
