Abstract
Description
Technical Field
[0001] The present application relates to the field of automobile seat ventilation devices, and in particular to a ventilation sealing device for improving seat comfort. Background Art
[0002] The seats of some current mid- to high-end vehicles need to ensure the comfort of the drivers and passengers in harsh environments. When the vehicle enters high-temperature areas and hot environments, the drivers and passengers can turn on the seat ventilation function on the vehicle to achieve the need to cool down the drivers and passengers.
[0003] The current traditional ventilation device includes an air bag and a blower connected to the air bag. After the driver or passenger turns on the ventilation function, the blower will blow air into the air bag, and the air will be dispersed to the seat cushion and / or backrest through the air outlet of the air bag.
[0004] However, the inventor believes that due to the relatively poor sealing of traditional air bags, the air output of the seat is slightly insufficient and cannot meet the comfort requirements of the driver and passengers. Therefore, it is necessary to design a device with better sealing to meet the comfort needs of the passengers. Utility Model Content

[0006] The present application provides a ventilation and sealing device for improving seat comfort, which adopts the following technical solution:
[0007] A ventilation sealing device for improving seat comfort comprises an air bag and a blower connected to the air bag, the air bag comprises an air bag body and a PP sealing bag, the PP sealing bag is coated on the outside of the air bag body or the air bag body is coated on the outside of the PP sealing bag, an air inlet is arranged at one end of the air bag body, a first sealing sleeve pipe is connected to the air inlet, the first sealing sleeve pipe is connected to a U-shaped air duct, the U-shaped air duct is connected to an air outlet interface of the blower, a plurality of air outlet holes are arranged on the side of the air bag body facing the seat cushion, and through holes are arranged on the PP sealing bag, the positions and numbers of which match those of the air outlet holes.
[0008] Optionally, the air bag body and the PP sealing bag are fixedly connected by ultrasonic welding.
[0009] Optionally, the air bag body and the PP sealing bag have the same shape.
[0010] Optionally, the U-shaped air duct is connected to the air outlet interface of the blower via a second sealing sleeve pipe, and the air outlet interface of the blower is connected to the second sealing sleeve pipe by a snap-fitting manner.
[0011] Optionally, a snap-in protrusion is provided at the air outlet interface of the blower, and a snap-in groove matched with the snap-in protrusion is provided on the inner wall of the connecting end of the second sealing sleeve pipe and the air outlet interface of the blower.
[0012] Optionally, the air inlet of the blower is arranged on the side opposite to the air outlet of the air bag body.
[0013] To summarize, the present application includes at least one of the following beneficial technical effects: by arranging a PP sealing bag and a U-shaped air duct in the air bag to achieve sealing between the air bag and the blower, and connecting the air inlet and the U-shaped air duct through a first sealing sleeve, the sealing performance is further improved, thereby increasing the air outlet of the seat, changing the problem of low ventilation volume of traditional car seats, and improving the ventilation performance and cooling effect of car seats, so as to better meet the comfort needs of drivers and passengers.
