A seat with a zoned ventilation function

Abstract

A seat with zoned ventilation includes seat foam, an A-side fan, an A-side ventilation medium, a B-side fan, and another B-side ventilation medium. The A-side of the seat foam has N ventilation zones, each with an inner groove. A wire-passing hole is located at the bottom of the inner groove. The A-side fan is positioned within the inner groove of the seat foam. The A-side ventilation medium covers the A-side foam and serves to fix the A-side fan while simultaneously distributing the airflow from the A-side fan evenly within the ventilation zones. The B-side fan is connected to the B-side ventilation medium and then fixed to the B-side of the seat foam, directing airflow through the B-side ventilation medium into the ventilation holes on the A-side of the seat foam. This seat miniaturizes and zones the fans, solving the problem of insufficient space for electrical components in the seat. It also allows for different combinations of ventilation methods, such as localized ventilation and zoned blowing / suction, as needed.

[0007] As a preferred embodiment of this utility model, the A-side fan is connected to the A-side ventilation medium, and the wires on the A-side fan pass through the wire hole and are connected to the controller inside the seat. The B-side fan is connected to the B-side ventilation medium, and the B-side ventilation medium is embedded in the B-side of the seat foam. The B-side ventilation medium has an internal air duct and is airtight around it. The air is directed to the ventilation holes of the A-side of the seat foam through the B-side ventilation medium.

[0008] As a preferred embodiment of this utility model, the ventilation medium on side A is a 3D mesh structure, and the ventilation medium on side B is a 3D mesh structure covered with an airtight layer.

[0009] As a preferred embodiment of this utility model, the ventilation medium on surface A is a 3D mesh structure that mimics the shape of the seat in the corresponding ventilation area.

[0010] Advantages and beneficial effects of this utility model:

[0011] (1) The seat provided by this utility model can use a small fan on the backrest, so it can reserve more space for the backrest area and avoid interference with the kneading massage structure installed inside the backrest.

[0012] (2) The miniaturized and partitioned arrangement of the seat fan provided by this utility model can be flexibly arranged according to the actual situation, solving the problem of insufficient space for electrical components in the seat.

[0013] (3) After the seat provided by this utility model is divided into different areas for ventilation, the B-side fan or A-side fan of the seat can be powered on individually or simultaneously to realize different combinations of ventilation methods such as local ventilation and zoned blowing and suction, so as to meet the needs of different drivers and passengers.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0019] like Figures 1 to 3 As shown, this embodiment provides a seat with zoned ventilation function, including seat foam 3, A-side fan 4, A-side ventilation medium 5, B-side fan 1, B-side ventilation medium 2, and seat cover 6; wherein, the A-side of the seat foam has N ventilation areas, and this embodiment has 4, namely the left wing ventilation area A, the right wing ventilation area B, the left shoulder ventilation area C, and the right shoulder ventilation area D. Each ventilation area has an inner groove 302, and the bottom of the inner groove has a wire hole 303. The A-side fan is set (installed by embedding) in the inner groove 302 of the seat foam 3, and the wire on it passes through the wire hole 303 and connects to the controller inside the seat. The A-side of the seat foam is covered with the A-side ventilation medium 5, which is used to fix the A-side fan 4 and at the same time distribute the air drawn out by the A-side fan 4 evenly in the ventilation area;

[0020] The B-side fan 1 is connected to the B-side ventilation medium 2 and then fixed to the B-side of the seat foam 3. The B-side ventilation medium 2 has an internal air duct and is airtight. The A-side of the seat foam 3 has a ventilation hole 301 that communicates with the air duct in the B-side ventilation medium 2 at a position opposite to the B-side ventilation medium. The air is guided into the ventilation hole 301 on the A-side of the seat foam through the B-side ventilation medium. There are multiple ventilation holes 301 and they are arranged at intervals in the central ventilation area E of the seat.

[0021] The seat cover 6 covers the ventilation medium 5 on side A. The seat cover 6 has perforations or ventilation structures to ensure that the air volume transmitted in the ventilation medium on side A and side B can reach the seat surface through the seat cover 6.

[0022] Furthermore, in this embodiment, the A-side fan 4 is connected to the A-side ventilation medium 5, the B-side fan 1 is connected to the B-side ventilation medium 2, and the B-side ventilation medium 2 is embedded in the B-side of the seat foam 3; the A-side ventilation medium 5 is a 3D mesh fabric (also known as 3D spacer fabric) structure, and the B-side ventilation medium 2 is a 3D mesh fabric structure covered with an airtight layer.

[0023] Furthermore, such as Figure 3As shown, in this embodiment, the ventilation medium 5 on surface A is a 3D mesh structure that mimics the shape of the seat corresponding to the left wing ventilation area A, right wing ventilation area B, left shoulder ventilation area C, and right shoulder ventilation area D.

[0024] In this embodiment, the traditional large fan is divided into multiple independent small fans and arranged in zones according to area. This method allows for the use of small fans on the backrest, thus reserving more space for the backrest area and avoiding interference with the kneading massage structure installed inside the backrest. In addition, the miniaturized and zoned arrangement of the fans can be flexibly arranged according to actual conditions, solving the problem of insufficient space for electrical components in the seat. Finally, after the seat is divided into different areas for ventilation, the B-side fan or A-side fan of the seat can be powered individually or simultaneously to achieve different combinations of ventilation methods such as local ventilation and zoned blowing and suction, in order to meet the needs of different drivers and passengers.
