Arrangement structure of a seat ventilation device

Abstract

The invention discloses an arrangement structure of a seat ventilation device. The structure comprises a seat cushion bearing basin, a sponge bearing pad, a fan, a wind guide layer and a breathable skin, the sponge bearing pad is arranged on the seat cushion bearing basin and provided with a sunk fan framework area which is provided with an air inlet passage hole penetrating through the sponge bearing pad, the seat cushion bearing basin is provided with an airway circulating hole communicated with the air inlet passage hole, the fan is arranged in the sunk fan framework area, and the wind guide layer and the breathable skin are arranged on the sponge bearing pad and positioned on an upper side of the fan. By arranging the sponge bearing pad in the sunk fan framework area, noise inhibition of the fan is effectively realized, and better and quieter environmental comfortableness is provided for a seat user.

Description

technical field [0001] The invention relates to the technical field of car seats, and more specifically, relates to an arrangement structure of a seat ventilation device. Background technique [0002] In recent years, with the advancement of seat comfort system technology, the seat with air exchange function has become a new type of comfortable product that is gradually accepted by people. Through the air exchange between the seat surface and the interior of the seat surface, a better local environmental interface between the seat and the body surface of the occupant can be achieved. Especially in summer and other seasons when the human body is prone to sweating, it is more conducive to perspiration and refreshing on the body surface of the seat occupant. [0003] A simple application of this type of seat ventilation is to place a small fan under a vehicle seat, such as on the seat pan. This type of ventilation device is to use the wind generated by the fan to act on the h...

Problems solved by technology

[0004] However, due to the continuous improvement of people's requirements for a comfortable environment, the noise problem caused by the operation of the fan has gradually become an important factor for users to complain

The fan is arranged under the vehicle seat, such as the relatively open external space on the seat bottom, so that such technical products often cause users to complain about the wind noise and mechanical noise generated by the fan

[0005] At the same time, the above-mentioned technical products also have the problem that because the fan is in a relatively open external space, it often runs in a relatively dirty air environment such as dust, which leads to accelerated loss of the fan shaft and reduces the effective service life of the entire ventilation device.
