Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a seat cushion fan installation structure. Background Art

[0002] As the frequency of car use increases, passengers' requirements for car comfort are gradually increasing. At present, some car seats are equipped with car seat fans. Existing car seat fans are mostly installed on the car seat frame through connectors and connected to the wind bag through ventilation ducts to supply air to the wind bag. The wind in the wind bag passes through the seat foam and enters the top of the seat, thereby cooling the buttocks, thighs and other parts of the human body; but the ventilation duct is complex and easily compressed, which makes the seat fan have a small ventilation volume, large wind resistance, low ventilation efficiency, and high cost. Utility Model Content

[0003] In view of the problems existing in the above-mentioned prior art, the utility model aims to provide a seat cushion fan installation structure to solve the problem of low ventilation efficiency of the existing seat cushion fan.

[0004] In order to achieve the above-mentioned purpose, the utility model proposes a seat cushion fan mounting structure, comprising a fan, an air bag and a seat basin sheet metal, the seat basin sheet metal is provided with a vent, the fan is mounted below the vent, the air outlet of the fan is docked with the vent, and a sealing ring is connected to the air outlet of the fan, the air bag is mounted above the seat basin sheet metal, and the sealing ring passes through the vent and is connected to the air inlet of the air bag.

[0005] In the above scheme: the fan is fixed to the seat basin sheet metal by rubber rivets, and is thus installed below the vent of the seat basin sheet metal, which has a simple structure and is easy to install.

[0006] In the above scheme: the sealing ring is clamped in the vent, the front side of the sealing ring is bonded and fixed to the air inlet of the wind bag, the sealing ring can be integrated with the fan, and the sealing ring is passed through the vent and bonded and fixed to the wind bag during assembly. It has a simple structure and is easy to install, and the sealing ring is clamped in the vent to avoid abnormal noise caused by friction.

[0007] In the above scheme: the seat cushion fan installation structure also includes a seat cushion foam, the wind bag is bonded and fixed to the back of the seat cushion foam, and the seat cushion foam is provided with ventilation holes that are connected to the air outlet holes of the wind bag. The structure is simple and the installation is convenient.

[0008] In the above scheme: the back of the foamed seat cushion is provided with an installation cabin for embedding the air bag, which saves installation space and is convenient for installation.

[0009] In the above scheme: triangular limiting protrusions are provided on the left, right and front sides of the air bag, and limiting grooves matching with the limiting protrusions are provided on the seat cushion foam. The limiting protrusions cooperate with the limiting grooves to limit the air bag front, back, left and right.

[0010] The beneficial effect of the utility model is that by arranging the vents on the seat basin sheet metal, the air outlet of the fan passes through the vents through the sealing ring and is directly connected to the air inlet of the air bag. Compared with the traditional seat cushion fan system (the fan is connected to the air bag through the ventilation duct), the utility model effectively improves the ventilation efficiency of the seat cushion fan, reduces wind resistance, and eliminates the ventilation duct parts, which is conducive to reducing costs.
