Description

Automotive Ventilated Seat Structure

technical field

The utility model relates to a seat structure, in particular to an automobile ventilated seat structure with good ventilation effect.

Background technique

At present, the automobile industry is developing rapidly, and it is necessary to pursue comfort while improving technology. In order to improve the comfort when driving and riding in a car, some cars are equipped with ventilated seats, which can take away heat and improve comfort when the human body is in contact with the seat.

Taiwan Patent No. 093213364 discloses a breathable car seat structure. The seat structure uses a fan to introduce air into a three-layer breathable cushion and then leads it out through a cushion cover and a backrest cover with vent holes to take away the human body. Heat at the point of contact with the seat. In this seat structure, since the air passes through at least three layers of air-permeable cushions, the air is exported through the cushion cover and the back-to-back cover. Ventilation holes will also become blocked due to extrusion, especially the vent holes on the contact surface between layers, causing most of the air to flow back, reducing the ventilation effect, and its air cushion is multi-layered and has a complex structure. It is more troublesome.

In addition, Taiwan Patent No. 092211450 also discloses a car heat dissipation seat, which is provided with an air inlet and an air outlet on the elastic seat body or the outer layer relative to the cage mesh liner, and the air flow is sent into the seat through the air inlet. The cage net liner is then covered by the outer layer, and flows along the range covered by the cage net liner to the air outlet for discharge. In the heat dissipation seat, since there is a connecting channel between the air inlet and the air outlet, when the air enters the seat through the air inlet, most of the air will be discharged from the air outlet through the connecting channel between the air inlet and the air outlet without hindrance. The airflow entering the cage mesh pad can only account for a small part of the airflow at the air inlet under the action of the pressure of the human body seat, so its heat dissipation effect is relatively low.

In order to solve the defects of low cooling effect and complex structure in the above-mentioned prior art, the designer of the utility model finally created a car ventilated seat structure through continuous research and experiments.

Utility model content

The purpose of the utility model is to provide a car ventilated seat structure, which has good heat dissipation effect, simple structure and easy manufacture.

The automobile ventilated seat structure of the utility model comprises a seat, a backrest and an air supply device respectively installed on the seat and the backrest; the seat includes a seat cover, a seat foam, a seat bottom, the seat foam Cotton is arranged on the seat bottom plate, and the seat cover is coated on the seat foam; the backrest includes a back seat cover, a back foam, a back frame, a back trim, and the back trim is covered on the back frame On the outside, the back foam is arranged on the back frame, and the back seat cover is covered on the back foam; it is characterized in that at least one through-air air hole is opened on the seat foam and the back foam, close to One side of the human body seat surface, along the periphery of the air intake hole, radiates a number of air flow channels with a certain depth, and the air flow channels communicate with the air intake hole; the seat cover and the back seat cover are composed of The surface layer of the air hole and the filter layer are composed. The air supply device is connected with the air intake hole of the seat foam and the back foam, and the air is sent into each air flow channel through the air intake hole, and then passed through the seat cover. And the filter screen layer of the back seat cover and the ventilation holes of the surface layer make the air contact with the human body to realize heat exchange.

A ventilation rib is added to the upper and lower ends of the back trim relative to the back frame, through which the ventilation rib contacts the back frame to form a gap between the back trim and the back frame to enhance the air flow and improve the heat exchange effect.

The back-to-back air supply device is a fan, and the fan is fixed on the back foam through an inserted plastic part, so that the fan can maintain a certain distance from the back foam to ensure the ventilation effect.
