[0027] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] like Figures 1 to 4 As shown, one embodiment of this utility model provides a ventilated seat, including a seat foam 1, a fixing member 2, a fan 3, a first sealing structure 4, and a second sealing structure 5. The seat foam 1 is provided with an air duct and a pre-embedded part 6. The air duct has a ventilation opening 11 that penetrates the back of the seat foam 1 along a first direction. The pre-embedded part 6 is pre-embedded on the outside of the ventilation opening 11. Figure 3 D1 in the diagram represents the first direction.

[0029] The fastener 2 is connected to the embedded part 6, and the fan 3 is fixed on the side of the fastener 2 facing away from the seat foam 1. The fan 3 has a blow-in or suction port for blowing air into or drawing air from the air duct, and the fastener 2 has a through hole 21. The vent 11, the through hole 21, and the blow-in or suction port of the fan 3 are connected in sequence.

[0030] The first sealing structure 4 is located between the seat foam 1 and the fixing member 2, and the second sealing structure 5 is located between the fixing member 2 and the fan 3.

[0031] Understandably, the air duct also has a cooling port that runs through the front of the seat foam 1. When the blower 3 blows air into the air duct, the airflow flows into the air duct through the through hole 21 and the vent 11 in sequence, and flows out from the cooling port to cool the occupants on the seat; or, the blower 3 draws air from the air duct, and the air in front of the seat is drawn into the air duct through the cooling port, and then flows through the vent 11 and the through hole 21 in sequence to the blower 3, and is guided by the blower 3 to the rear of the vehicle.

[0032] The front of the seat foam 1 is the side covered with the skin, which is the side for passengers to sit on and support. Correspondingly, the back of the seat foam 1 is the side of the seat foam 1 that faces away from the passengers.

[0033] In this ventilated seat, the fixing member 2 is connected to the embedded part 6 on the seat foam 1, and the fan 3 is fixed to the fixing member 2, so that the fan 3 is installed on the seat foam 1 through the fixing member 2. Moreover, the through hole 21 of the fixing member 2 connects the blowing and suction port of the fan 3 and the ventilation port 11 of the air duct of the seat foam 1, so that the fan 3 can directly blow air into the air duct or draw air from the air duct to realize the ventilation function of the ventilated seat. A first sealing structure 4 is provided between the fixing member 2 and the seat foam 1, and a second sealing structure 5 is provided between the fixing member 2 and the fan 3 to ensure the airtightness of the entire channel when the fan 3 blows air into the air duct or draws air from the air duct.

[0034] Compared to the existing technology where the fan 3 is mounted on the seat frame or spring frame via a bracket and the fan 3 is connected to the ventilation opening 11 of the seat foam 1 via a duct, the fan 3 is mounted on the seat foam 1 via a fastener 2. The fan 3 and the ventilation opening 11 of the seat foam 1 do not need to be connected via a duct, which simplifies the structure, reduces the number of parts, lowers the cost, and facilitates later maintenance.

[0035] In one embodiment, the first sealing structure 4 is integrally formed with the back of the seat foam 1, and the first sealing structure 4 is arranged around the vent 11.

[0036] Since the material of seat foam 1 has certain shock absorption and sealing properties, the first sealing structure 4 can be formed by using the raw material of seat foam 1 during the processing of seat foam 1, without the need for additional sealing parts, thereby reducing the number of parts during the assembly of ventilated seats, reducing costs, and improving assembly efficiency.

[0037] Of course, in other embodiments, the first sealing structure 4 and the seat foam 1 can be set separately, and the first sealing structure 4 can be a sealing ring or sealing cotton.

[0038] In one embodiment, the second sealing structure 5 and the fixing member 2 are separately arranged. The fixing member 2 and the second sealing structure 5 require different performance characteristics. The fixing member 2 needs to have a certain structural strength to ensure the connection strength between the fixing member 2 and the fan 3 and the embedded part 6, while the second sealing structure 5 needs to have certain wear resistance and shock absorption performance to reduce the impact of the fan 3's vibration on the seat. Therefore, separating the second sealing structure 5 and the fixing member 2 allows them to be manufactured separately, simplifying the processing technology of the second sealing structure 5 and the fixing member 2.

[0039] In one embodiment, the second sealing structure 5 is sealing cotton, which surrounds the outside of the through hole 21 of the fixing member 2.

[0040] In one embodiment, sealing cotton adhesive is attached to the fastener 2.

[0041] In one embodiment, the sealing cotton is ring-shaped.

[0042] In one embodiment, the fixing member 2 is a fixing plate, with one side surface of the fixing plate pressing on the first sealing structure 4 and the second sealing structure 5 pressing on the other side surface of the fixing plate. The fixing plate has a simple structure and occupies little space.

[0043] In one embodiment, such as Figure 2 As shown, the fan 3 is detachably connected to the fixing part 2. When repairing or replacing the fan 3 in the future, the fan 3 can be removed from the fixing part 2 without removing the fixing part 2 from the seat foam 1, reducing the number of parts to be disassembled, facilitating the repair or replacement of the fan 3, and improving the convenience of after-sales replacement of the fan 3.

[0044] In one embodiment, the device further includes a plurality of elastic rivets 7. The fastener 2 is provided with a plurality of first connecting holes 22 that extend along the first direction. The fan 3 is provided with a plurality of pull holes 31. The plurality of first connecting holes 22 and the plurality of pull holes 31 are connected in a one-to-one correspondence. One end of the elastic rivet 7 passes through the first connecting hole 22 and is locked in the corresponding pull hole 31 to tighten the fan 3, so that the fan 3 is pressed on the second sealing structure 5.

[0045] Specifically, the elastic rivet 7 is a rubber rivet. The elastic rivet 7 has a certain elasticity. When the fan 3 rotates, the elastic rivet 7 can deform elastically to isolate or reduce the impact of fan vibration on the seat and improve the comfort of the ventilated seat.

[0046] In one embodiment, three elastic rivets 7 are provided. The fixing member 2 is provided with three first connecting holes 22 that are circumferentially spaced along the through hole 21. Correspondingly, the fan 3 is provided with three pull holes 31. The elastic rivet 7 includes a rod and a head connected to one end of the rod. The rod of each elastic rivet 7 passes through a first connecting hole 22 and is locked in the corresponding pull hole 31. The head of the elastic rivet 7 presses against the fixing member 2.

[0047] In one embodiment, such as Figure 2 As shown, the embedded part 6 and the fixing part 2 are detachably connected.

[0048] When repairing the ventilated seat later, the fastener 2, the fan 3 and the second sealing structure 5 fixed on the fastener 2 can be removed from the ventilated seat, so that the second sealing structure 5, the fastener 2 and the fan 3 can be repaired or replaced in a larger space, improving the convenience of after-sales maintenance and avoiding damage to the seat foam 1 and the embedded part 6 during destructive disassembly.

[0049] In one embodiment, such as Figure 2 and Figure 3 As shown, it also includes a threaded fastener 8. The fixing member 2 is provided with a second connecting hole 23 extending along the first direction. One end of the threaded fastener 8 passes through the second connecting hole 23 and is threadedly connected to the embedded part 6. The threaded fastener 8 has a simple structure and is easy to assemble and disassemble.

[0050] In one embodiment, the threaded fastener 8 is a self-tapping screw.

[0051] In one embodiment, the embedded part 6 includes an embedded head 61 and a connecting body 62. The connecting body 62 extends along a first direction, and the cross-sectional area of ​​the embedded head 61 is larger than that of the connecting body 62. One end of the connecting body 62 is connected to the embedded head 61, and the other end of the connecting body 62 extends out of the seat foam 1. A threaded fastener 8 is threadedly connected to the connecting body 62. Part of the connecting body 62 and the embedded head 61 are embedded in the seat foam 1 to increase the contact area between the embedded part 6 and the seat foam 1 and improve the firmness of the embedded part 6 on the seat foam 1.

[0052] In one embodiment, the embedded part 6 is a plastic part.

[0053] In one embodiment, such as Figure 2 As shown, the through hole 21 passes through the fixing member 2 along the first direction, and the ventilation port 11, the through hole 21 and the blow-in port of the fan 3 are connected in sequence along the first direction, so that the ventilation port 11, the through hole 21 and the blow-in port of the fan 3 form a channel extending along the first direction. The airflow flows unobstructed in the channel, so that the fan 3 can smoothly draw air from the air duct or blow air into the air duct.

[0054] In one embodiment, such as Figure 2 and Figure 4 As shown, there are three embedded parts 6, which are distributed at intervals along the circumference of the ventilation opening 11. Correspondingly, there are three second connecting holes 23 on the fixing part 2, and three self-tapping screws are provided. Each self-tapping screw passes through a second connecting hole 23 and is fastened in the corresponding embedded part 6.

[0055] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
