Detailed Description

Embodiments of the present invention are described below with reference to the drawings.

The drawings are for easy understanding of the present invention and show only the main structure, and the structure or specific shape thereof which does not affect the understanding of the technical means of the present invention may be omitted. In different embodiments, the same reference signs are used for the same or similar elements to facilitate comparison and understanding. In the following description, up, down, left, right, front, and rear are based on the direction viewed by an occupant seated in the seat. In addition, the following embodiments are drawn to show the seat as an example, only the portion related to the technical solution of the present application is expressed, and other portions (for example, the specific configuration, shape, etc. of the exterior and the interior of the seat) can adopt the technical solution known to those skilled in the art. At the same time, it will be appreciated by those skilled in the art that the teachings of the present application can be reasonably applied to similar seating structures.

Fig. 1 is a schematic sectional view of a vehicle seat according to an embodiment of the present invention. The vehicle seat 100 of the present embodiment may include two portions, namely, a seat back 102 and a seat bottom 104, which may selectively have a seat cover 110, a seat cushion 120, an air conditioning portion 130, and a ventilation duct 140, which may have air permeability, respectively or simultaneously. The seat skin 110 covers the seat cushion 120, and at least a part of the seat skin 110 is made of high performance fiber, for example, wherein a moisture absorbing material is used on one side contacting with the occupant, and a moisture discharging material is used on the other side. In this manner, moisture (e.g., perspiration) from the occupant can be absorbed by the seat skin 110 on the side in contact with the occupant, pass through the seat skin 110, and exit on the other side, wherein the temperature of the hygroscopic surface decreases as the moisture evaporates, giving the occupant a cooling sensation.

The air conditioning part 130, which is, for example, a bag combined with high performance fiber and made of a flexible material such as rubber, is located at the occupant side of the seat cushion body 120 and at the inner face of the seat skin 110, is connected to the ventilation duct 140, and is internally filled with a three-dimensional support structure. The three-dimensional support structure is, for example, a net structure formed by interlacing thermoplastic resin fibers. The air conditioner 130 is adapted to generate an internal volume change in response to a position change of a passenger, and to drive air to flow. The air conditioning part 130 made of the high performance fiber also has a dehumidifying function, and allows moisture to be discharged into the air conditioning part 130 along with the flow of air. The ventilation duct 140 is disposed in the seat cushion 120, and one end of the ventilation duct 140 is connected to the air conditioning unit 130, and the other end thereof penetrates through the seat skin 110 on the back side of the seat cushion 120 and is communicated with the outside. The air inside the air conditioner part 130 may be exchanged with the external air through the ventilation duct 140.

In other words, the air conditioning unit 130 and the ventilation duct 140 according to the present embodiment may be configured to allow air to enter or exit the air conditioning unit 140 through the ventilation duct 140 in response to a change in the position of the occupant on the vehicle seat 100, for example, deformation of the air conditioning unit due to vehicle running vibration. Air can penetrate through the seat cover 110 having air permeability to perform heat exchange between the occupant and the air conditioning part 140, thereby eliminating stuffiness of the occupant and improving comfort of the occupant.

Fig. 2 is a schematic view of the ventilation duct 140 according to the present embodiment. The ventilation duct 140 of the present embodiment includes an air intake passage 142 and an air exhaust passage 144 which are independent from each other, wherein in response to the deformation of the air conditioning portion 130, air on the back side of the seat cushion body 120 can enter the air conditioning portion 130 through the air intake passage 142, and air in the air conditioning portion 130 can leave the air conditioning portion 130 through the air exhaust passage 144 and be exhausted to the back side of the seat cushion body 120. Thus, since the air inlet path 142 and the air outlet path 144 are independent of each other, the mixture of the sucked air and the discharged air can be prevented, and a good air convection and heat exchange effect can be achieved.

In addition, in the present embodiment, it is also optional to provide switches in the intake passage 142 and the exhaust passage 144, respectively, for example, the intake passage 142 has a first switch 142a that can be opened or closed by the sucked air, and the exhaust passage 144 has a second switch 144a that can be opened or closed by the exhausted air. The first switch member 142a and the second switch member 144a are, for example, check valves driven by the forward air flow to prevent the reverse flow of the sucked air and the discharged air. In this way, the intake passage 142 and the exhaust passage 144 can be effectively distinguished, and the mixture of the sucked air and the exhausted air is avoided, thereby improving the efficiency of air exchange.

On the other hand, the air discharged from the ventilation duct 140 may affect the comfort of the other occupants when seated. For example, as shown in fig. 1, when the ventilation duct 140 is provided in the seat back 102 of, for example, a driver's seat or a passenger's seat, the discharged air may be blown toward other occupants behind the seat 100. Accordingly, the outlet structure or position of the ventilation duct 140 may be designed.

Fig. 3 is a schematic view of a ventilation duct of one embodiment of the present invention. In the present embodiment, a cover 150 is added to the ventilation duct 140 provided in the seat back 102 at the opening 148 of the ventilation duct 140. The housing 150 is spaced from the opening 148 to provide airflow in and out and covers the opening 148. Thus, the air duct 140 is not only aesthetically pleasing, but also prevents foreign matter from entering the air duct 140 to some extent, and also prevents the air discharged from the air duct 140 from being blown directly to other occupants in the rear, thereby preventing the other occupants from feeling uncomfortable.

Fig. 4 is a schematic view of a ventilation duct of one embodiment of the present invention. In the present embodiment, the ventilation duct 140 provided in the seat 104 is designed in the direction thereof. Specifically, the ventilation duct 140 in the seat bottom 104 extends toward the vehicle floor 10 to discharge air downward, so as to prevent the air discharged from the ventilation duct 140 from blowing directly onto other occupants. In addition, the design of this embodiment also allows for air exchange under the seat 104. For example, air blown out to the occupant's feet by the in-vehicle air conditioning system 12 is sucked in from below the seat bottom 104, and comfortable air is sent to the occupant through the air conditioning unit 130 and the ventilation duct 140, thereby improving the riding comfort.

As described above, the present invention improves the structure of a vehicle seat, and allows air to flow and exchange in the seat in response to a change in position of a passenger on the seat without using a fan or other device that consumes power and without consuming electric power of the vehicle. In addition, the independent air intake passage and the independent air exhaust passage can be used as ventilation pipelines, and the air intake passage and the air exhaust passage can be respectively provided with a switch piece, so that the corresponding technical effect is achieved. In order to avoid the influence of exhaust on other passengers, an outer cover can be arranged at the opening of the ventilation pipeline, and the trend of the ventilation pipeline can also be adjusted. The utility model can provide a vehicle seat which can eliminate stuffiness feeling of passengers and improve the comfort of the passengers under the condition of reducing unnecessary electric energy loss during the running of a vehicle.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
