DETAILED DESCRIPTION

[0055] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0056] In the present disclosure, unless otherwise stated, directional words such as "up, down, front, and rear" generally refer to the orientation of the vehicle seat 100 after it is normally installed on the vehicle. The up, down, front, and rear directions of the vehicle seat 100 are the same as the up, down, left, and right directions of the vehicle. "Inside and outside" refer to the inside and outside of the contours of the relevant parts. These directional words are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present disclosure. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0057] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0058] like Figures 1 to 32 As shown, according to one aspect of the present disclosure, a vehicle seat 100 is provided, which includes a seat cushion 10 and a backrest 20. A first internal air duct is provided in the seat cushion 10, and a first air outlet 11 for communicating with the first internal air duct is provided on the side of the seat cushion 10 for contact with the human body, for example, communicating with the air outlet of the first internal air duct. A second internal air duct is provided in the backrest 20, and a second air outlet 21 for communicating with the second internal air duct is provided on the side of the backrest 20 for contact with the human body, for example, communicating with the air outlet of the second internal air duct. A neck air outlet 22 is also provided at the upper part of the backrest 20, and the air flow flowing out of the neck air outlet 22 is used to act on the neck of the human body, that is, the position of the neck air outlet 22 on the backrest 20 can roughly correspond to the neck of the human body, so that the air flow flowing out of the neck air outlet 22 can act on the neck of the human body. The vehicle seat 100 further includes an air supply mechanism 30 , which is respectively connected to the air inlet of the first internal air duct, the air inlet of the second internal air duct and the neck air outlet 22 to provide warm air / cold air to the seat cushion 10 and to provide warm air / cold air to the backrest 20 .

[0059] In the vehicle seat 100 provided by the present disclosure, since the first air outlet 11 and the second air outlet 21 are respectively provided on the seat cushion 10 and the backrest 20, the air flowing into the vehicle seat 100 can be exchanged with the air in the vehicle's passenger compartment, so that the vehicle seat 100 can be ventilated, reducing the risk of breeding bacteria and generating odor. Moreover, by providing an air supply mechanism 30, warm air / cold air can be provided to the seat cushion 10 and the backrest 20 of the vehicle seat 100, and the vehicle seat 100 can be heated / cooled, which can meet the needs of the driver and passenger for rapid heating / cooling of the vehicle seat 100. In addition, since the vehicle seat 100 is also provided with a neck air outlet 22, in winter, the neck air outlet 22 is provided with warm air by the air supply mechanism 30, which can provide air supply health care to the neck of the driver and passenger, play a protective role on the human neck, and is conducive to providing customers with a more comfortable driving experience.

[0060] Among them, Figure 1 As shown, there may be multiple first air outlet holes 11 and multiple second air outlet holes 21, and the multiple first air outlet holes 11 and the second air outlet holes 21 may be smaller holes. The multiple first air outlet holes 11 may be evenly arranged on the seat cushion 10, and the multiple second air outlet holes 21 may be evenly arranged on the backrest 20 and correspond to the positions of the human back.

[0061] In addition, optionally, a ventilation bag (not shown) can be arranged at the lower end of the seat cushion 10. The lower end of the ventilation bag is sealed and provided with an air inlet, and its upper surface is provided with a porous air outlet structure, which can correspond to the holes in the seat sponge layer. An independent uniform wind structure can be set in the middle of the ventilation bag to evenly release the heated / cooled air on the seat sponge layer. The leather layer on the surface of the seat is provided with many micropores, that is, the above-mentioned first air outlet 11 and second air outlet 21. In this way, the air can eventually be exchanged with the air in the cockpit from the first air outlet 11 and the second air outlet 21.

[0062] In the present disclosure, the air supply mechanism 30 for supplying air to the seat cushion 10 and the backrest 20 may share one or may have separate air supply mechanisms, which is not limited in the present disclosure. Figure 2As shown, the air supply mechanism 30 may include a first air supply mechanism 40 and a second air supply mechanism 50, the first air supply mechanism 40 is used to provide warm air / cold air to the seat cushion 10, and the second air supply mechanism 50 is used to provide warm air / cold air to the backrest 20. In this embodiment, the seat cushion 10 and the backrest 20 use separate air supply mechanisms 30. In this way, the first air supply mechanism 40 and the second air supply mechanism 50 can be flexibly set to the corresponding structure and layout position according to the position and structure of the seat cushion 10 and the backrest 20, which is conducive to simplifying the structure. For example, the position and structure of the first air supply mechanism 40 and the second air supply mechanism 50 can be flexibly arranged according to the position of the air inlet of the first internal air duct and the air inlet of the second internal air duct on the seat cushion 10 and the backrest 20.

[0063] The present disclosure does not limit the specific structure of the first air supply mechanism 40. Optionally, Figure 3 and Figure 4 As shown, in one embodiment of the present disclosure, the first air supply mechanism 40 may include a first air supply member 41 and a first external air duct 42, the air outlet of the first external air duct 42 is connected to the air inlet of the first internal air duct, and the first air supply member 41 is used to deliver the air inside the vehicle to the air inlet of the first external air duct 42. The first external air duct 42 may be installed on the bottom side of the seat cushion 10, and the first air supply member 41 may be a fan or a blower.

[0064] like Figure 5 As shown, the first air supply mechanism 40 also includes a semiconductor cooling sheet 60 disposed in the first external air duct 42, the semiconductor cooling sheet 60 includes a first material portion 61, a second material portion 62, and a first partition plate 63 for thermally isolating the first material portion 61 from the second material portion 62, the air flowing through the first material portion 61 can flow into the first internal air duct, the first external air duct 42 is provided with a first exhaust outlet, and the air flowing through the second material portion 62 flows out from the first exhaust outlet 4243. The first air supply mechanism 40 also includes a first conversion switch (not shown), the first conversion switch is electrically connected to the semiconductor cooling sheet 60, and is used to convert the cold end and the hot end of the semiconductor cooling sheet 60, so as to heat / cool the air from the vehicle by using the first material portion 61 and dissipate heat by using the second material portion 62 through the Peltier effect.

[0065] In this embodiment, the first material portion 61 of the semiconductor refrigeration sheet 60 is one of the N-type material and the P-type material, and the second material portion 62 of the semiconductor refrigeration sheet 60 is the other of the N-type material and the P-type material. When the semiconductor refrigeration sheet 60 is powered on, according to the Peltier effect, one of the N-type material and the P-type material can heat the air of the first air supply member 41, and the other cools it. The first material portion 61 and the second material portion 62 of the semiconductor refrigeration sheet 60 can be formed as a hot end and a cold end. Moreover, the cold end and the hot end of the semiconductor refrigeration sheet 60 can be switched by the first switching switch. In this way, in summer, the first material portion 61 can be used as a cold end. In winter, the first material portion 61 can be used as a hot end to heat / cool the air, thereby providing warm air / cold air to the seat cushion 10 of the vehicle seat 100 to achieve heating / cooling of the seat cushion 10 of the vehicle seat 100. The air flowing through the second material portion 62 can flow out into the vehicle cabin through the first exhaust port 4243 , realizing the heat dissipation of the semiconductor refrigeration plate 60 itself, thereby facilitating the normal operation of the semiconductor refrigeration plate 60 and ensuring the heating / cooling effect of the air flowing to the seat cushion 10 .

[0066] Furthermore, since the temperature regulation of the seat cushion 10 is independent of the vehicle air conditioning system, when there are fewer people in the vehicle, the vehicle air conditioning system can be turned off, and the temperature of the vehicle seat 100 can be regulated using the air supply mechanism alone, which is beneficial to energy saving.

[0067] The principle of the semiconductor cooling sheet 60 using the Peltier effect to heat / cool the airflow is well known to those skilled in the art, so it will not be described in detail here.

[0068] It should be noted that, in addition to using the Peltier effect to heat or cool the air, in other embodiments of the present disclosure, other heating / cooling structures may also be used, such as being connected to the vehicle's air conditioning system, or using other heating / cooling hot standby to heat / cool the air.

[0069] In addition, the above describes an embodiment in which the first external air duct 42 is used to supply air to the seat cushion 10 . However, in other embodiments of the present disclosure, the first air supply mechanism 40 may be integrated inside the seat cushion 10 .

[0070] The present disclosure does not limit the specific structure and shape of the first external air duct 42. Figure 3 and Figure 4As shown, in one embodiment of the present disclosure, the first external air duct 42 may include a main body section 421 and a first outlet section 422, the semiconductor cooling sheet 60 is installed on the main body section 421, and the size of the air inlet of the first outlet section 422 is adapted to the size of the cross section of the first material portion 61 of the semiconductor cooling sheet 60. "Adaptation" here means that the size of the air inlet of the outlet section is equal to or approximately equal to the size of the cross section of the first material portion 61 of the semiconductor cooling sheet 60. In this way, the heated / cooled air flowing out through the first material portion 61 can basically all flow into the first internal channel through the outlet section, and then flow into the seat cushion 10, which can enhance the heating / cooling effect on the seat cushion 10, and at the same time, it is also helpful to reduce the size of the outlet section, and correspondingly, it is helpful to reduce the size of the opening on the seat cushion 10 of the vehicle seat 100 that docks with the outlet section.

[0071] Furthermore, in the main body section 421, in order to prevent the airflow from the first material portion 61 and the second material portion 62 from mixing and affecting the heating / cooling of the seat cushion 10, in one embodiment of the present disclosure, a wind baffle (not shown) may be provided in the main body section 421 to block the airflow from the first material portion 61 and the second material portion 62.

[0072] In order to facilitate the quick connection of the first external air duct 42 and the first internal air duct, as shown in FIG. Figure 3 As shown, in one embodiment of the present disclosure, a first slot 4251 is provided on the outer wall of the first external air duct 42, and a first elastic latch (not shown) for engaging with the first slot 4251 is provided in the first internal air duct. In this way, after the first external air duct 42 is inserted into a certain position in the first internal air duct, the first elastic latch can engage with the first slot 4251, thereby achieving connection between the two, which is convenient for operation. Figure 3 As shown, the first slot 4251 may be disposed on an outer side wall of the first outlet section 422 .

[0073] The present disclosure does not limit the specific structure and shape of the first external air duct 42. Optionally, Figure 3 and Figure 4 , Figures 6 to 10 As shown, in the present disclosure, the first external air duct 42 includes a first transition air duct 426 section, a first shell 423, a second shell 424 and a third shell 425, the second shell 424 and the third shell 425 are respectively matched with the first shell 423 up and down to form an air duct, wherein the third shell 425 and the corresponding part of the first shell 423 are defined as the outlet section of the first external air duct 42, and the air duct section defined by the corresponding part of the second shell 424 and the first shell 423 and the passing air duct section together constitute the main section 421 of the first external air duct 42. The semiconductor cooling sheet 60 is installed on the air duct section defined by the corresponding part of the second shell 424 and the first shell 423.

[0082] The specific structure of the second air supply mechanism 50 is not limited in the present disclosure.

[0083] The second air supply mechanism 50 further includes another semiconductor cooling sheet 60 disposed in the second external air duct 52. The structure of the other semiconductor cooling sheet 60 may be the same as that of the semiconductor cooling sheet 60 in the first external air duct 42. Figure 5 As shown, the semiconductor cooling sheet 60 includes a first material portion 61, a second material portion 62, and a partition 63 for thermally isolating the first material portion 61 from the second material portion 62.

[0084] As mentioned above, the first material portion 61 of the semiconductor refrigeration sheet 60 is one of the N-type material and the P-type material, and the second material portion 62 of the semiconductor refrigeration sheet 60 is the other of the N-type material and the P-type material. When the semiconductor refrigeration sheet 60 is powered on, according to the Peltier effect, one of the N-type material and the P-type material can heat the air of the second air supply member 51, and the other cools it. The first material portion 61 and the second material portion 62 of the semiconductor refrigeration sheet 60 can be formed as a hot end and a cold end. And through the second conversion switch, the cold end and the hot end of the semiconductor refrigeration sheet 60 can be converted. In summer, the first material portion 61 can be used as a cold end. In winter, the first material portion 61 can be used as a hot end to heat / cool the air, thereby providing warm air / cold air to the backrest 20 of the vehicle seat 100, so as to achieve heating / cooling of the backrest 20 of the vehicle seat 100. The air flowing through the second material part 62 can flow out into the vehicle cabin through the second exhaust port 527, realizing the heat dissipation of the semiconductor refrigeration plate 60 in the second external air duct 52, which is beneficial to the normal operation of the semiconductor refrigeration plate 60 and ensures the heating / cooling effect of the air flowing to the backrest 20.

[0085] It should be noted that the above describes an embodiment in which the second external air duct 52 is used to supply air to the backrest 20 . However, in other embodiments of the present disclosure, the second air supply mechanism 50 may be integrated inside the backrest 20 .
