[0058] Obviously, the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. Those skilled in the art can know that with the development of technology and the appearance of new scenes, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0059] The terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, product, or device.

[0060] In the current passenger car, an air conditioning system is generally configured to reduce the temperature in the vehicle to provide a comfortable driving experience for passengers. The air conditioning system of the passenger car includes an air conditioning box and a plurality of air conditioning air outlets, wherein the air conditioning box is used to generate air conditioning cold air, and the air conditioning air outlets are used to discharge the air conditioning cold air into the vehicle. Please refer to Figure 1 In order to meet the cooling needs of the rear passengers, the air conditioning air outlet is usually arranged at the rear side of the auxiliary instrument panel. However, the size of the auxiliary instrument panel is small, so the effective blowing area and the air guiding amount of the air conditioning air outlet are limited. In addition, since the auxiliary instrument panel is usually arranged at the middle of the vehicle, when there are many passengers in the rear, the air conditioning air outlet cannot consider all the passengers, for example, if the air conditioning air outlet guides air to the left side, it cannot blow air conditioning cold air to the passengers in the middle and the right side. In addition, for automobile manufacturers, arranging the air conditioning air outlet at the rear side of the auxiliary instrument panel will limit the storage space at the rear side of the auxiliary instrument panel, and various difficulties will be encountered in the specific structural arrangement.

[0061] The embodiments of the present application provide a seat for providing better cold air or warm air blowing effect for passengers of a vehicle.

[0062] The seat in the embodiments of the present application can be arranged in the cabin of various vehicles, for example, a car, an airplane, a train, and a ship, and an air conditioning box for generating air conditioning air flow is arranged in the vehicle. Please refer to Figure 2The seat in the embodiments of the present application comprises a seat cushion (a), a seat back (b) and an air duct (c). The air duct (c) comprises an inlet (d) and a first outlet (e). The inlet (d) is arranged at the bottom of the seat cushion (a) and is connected with a blowing air duct (f) of a vehicle, and the blowing air duct (f) is further connected with an air conditioning system (g) of the vehicle, so as to deliver air conditioning air flow generated by the air conditioning system (g) to the inlet (d). The air conditioning air flow can be air conditioning cold air or air conditioning warm air. The first outlet (e) is close to and faces the rear of the seat back (b), so as to discharge the air conditioning air flow from the rear of the seat back (b). Based on the above design, the passenger located at the rear of the seat can be directly blown by the air conditioning air flow, and the area of the rear of the seat is large, so as to ensure sufficient air guiding amount.

[0063] On the basis of the above, Figure 3 In a possible implementation, the seat further comprises a headrest (h), and the air duct (c) further comprises a second outlet (i) and a third outlet (j). The second outlet (i) is arranged at the headrest (h), so as to discharge the air conditioning air flow from the headrest (h). The third outlet (j) is close to and faces the front of the seat back (b), so as to discharge the air conditioning air flow from the front of the seat back (b). It should be understood that Figure 3 The two wavy symbols shown in the figure only represent the omission of the part of the air duct (c) except the second outlet (i) and the third outlet (j).

[0064] Please refer to Figure 4 In a possible implementation, the air duct (c) further comprises a first control valve (k) arranged inside the seat back (b), a first air duct (l) and a second air duct (m). The first control valve (k) is provided with a first interface (k1), a second interface (k2) and a third interface (k3), and further comprises a first flow guiding device (k4) arranged inside the first control valve (k). The first flow guiding device (k4) comprises a plurality of first wind blocking pieces (k5) arranged in a fan shape. One end of the first air duct (l) is the inlet (d), and the other end of the first air duct (l) is connected with the first interface (k1), so as to deliver the air conditioning air flow to the first interface (k1). The second interface (k2) is connected with one end of the second air duct (m), and the other end of the second air duct (m) is the first outlet (e). The third interface (k3) is connected with the second outlet (i) and the third outlet (j). The first flow guiding device (k4) is capable of rotating. When the plurality of first wind blocking pieces (k5) are located at a preset position, the first interface (k1), the second interface (k2) and the third interface (k3) are not blocked; or the first interface (k1), the second interface (k2) and the third interface (k3) are not blocked; or the first interface (k1), the third interface (k3) and the second interface (k2) are not blocked; or the first interface (k1), the second interface (k2) and the third interface (k3) are blocked.Figure 4 For example, Figure 4 The positions of the multiple first windbreaks (k5) shown are such that they do not obstruct the first interface (k1), the second interface (k2), or the third interface (k3). Alternatively, please refer to [link to relevant documentation]. Figure 5 The first diversion device (k4) is in Figure 4 After rotating 30 degrees clockwise from the position shown, the position is as follows: Figure 5 As shown. It is easy to see that the positions of the multiple first windshield components (k5) at this time are such that they do not block the first interface (k1), the second interface (k2), or the third interface (k3). Alternatively, please refer to Figure 6 The first diversion device (k4) is in Figure 4 After rotating 30 degrees counterclockwise from the position shown, the position is as follows: Figure 6 As shown. It is easy to see that the positions of the multiple first windshield components (k5) at this time are such that they do not block the first interface (k1), the second interface (k2), or the third interface (k3). Alternatively, please refer to Figure 7 The first diversion device (k4) is in Figure 4 After rotating 60 degrees clockwise from the position shown, the position is as follows: Figure 7 As shown. It is not difficult to see that at this time, the positions of the multiple first windshield components (k5) are exactly blocking the first interface (k1), blocking the second interface (k2), and blocking the third interface (k3).

[0065] In one possible implementation, please refer to Figure 8a The first wind deflector (k5) consists of a connecting rod (k501) and a deflector head (k502). The connecting rods (k501) of multiple first wind deflectors (k5) are connected to the same rotating shaft, allowing them to switch positions under the drive of the shaft. Because the connecting rods (k501) are small, they do not significantly obstruct the airflow of the air conditioner. The deflector heads (k502) of the multiple first wind deflectors (k5) are used to block any number of air vents from the first interface (k1), second interface (k2), and third interface (k3). Of course, Figure 8a The diagram shown is only one implementation of the first windshield (k5). The first windshield (k5) can also be implemented in other forms, such as replacing the connecting rod (k501) with other connecting devices with ventilation holes, or the shape of the windshield head (k502) can also be different. Figure 8a The shape settings shown are not detailed here.

[0066] In addition, the air duct (c) also includes a second control valve (n), a third air duct (o), a fourth air duct (p), and a fifth air duct (q), all located within the same chair back (b). Please refer to [link / reference]. Figure 8bThe fourth interface (n1), the fifth interface (n2) and the sixth interface (n3) are arranged on the second control valve (n), and the second control valve (n) is internally provided with a second flow guide device (n4). The second flow guide device (n4) comprises a plurality of second wind blocking pieces (n5) arranged in a fan shape. The third air duct (o) is connected with the third interface (k3) and the fourth interface (n1) at two ends, and the air conditioner airflow can enter the second control valve (n) through the third interface (k3), the third air duct (o) and the fourth interface (n1). The fifth interface (n2) is connected with one end of the fourth air duct (p), and one end of the sixth interface (n3) is connected with one end of the fifth air duct (q). The other end of the fourth air duct (p) and the other end of the fifth air duct (q) are the second outlet (i) and the third outlet (j) respectively. The second flow guide device (n4) can rotate. When the plurality of second wind blocking pieces (n5) are located at a preset position, the fourth interface (n1), the fifth interface (n2) and the sixth interface (n3) are not blocked; or the fourth interface (n1), the fifth interface (n3) and the sixth interface (n2) are not blocked; or the fourth interface (n1), the sixth interface (n3) and the fifth interface (n2) are not blocked; or the fourth interface (n1), the fifth interface (n2) and the sixth interface (n3) are blocked. The specific implementation principle is similar to the foregoing description of the first control valve (k), which will not be described here.

[0067] In a possible implementation, referring to Figure 8c The second wind blocking piece (n5) is composed of a connecting rod (n501) and a wind blocking head (n502). The connecting rods (n501) of the plurality of second wind blocking pieces (n5) are connected to the same rotating shaft, and are switched in position under the driving of the rotating shaft, and because the volume of the connecting rod (n501) is small, it will not block the air conditioner airflow too much. The wind blocking head (n502) of the plurality of second wind blocking pieces (n5) is used to block any number of air outlets in the fourth interface (n1), the fifth interface (n2) and the third interface (n3). Of course, Figure 8c The second wind blocking piece (n5) is only one of the implementation manners, and the second wind blocking piece (n5) can also be implemented in other forms, for example, the connecting rod (n501) is replaced by other connecting devices with air holes, or the shape of the wind blocking head (n502) can also be set without the shape shown in Figure 8c The specific details will not be described here.

[0068] By arranging the first control valve (k) and the second control valve (n), after the air conditioner airflow is delivered to the first interface (k1), whether the air conditioner airflow can be discharged from the first outlet (e), the second outlet (i) and the third outlet (j) can be flexibly controlled.

[0069] In a possible implementation, please refer to Figure 9 , the first air duct (l) can include an air purifier (r), a sixth air duct (s), and a seventh air duct (t). One end of the seventh air duct (t) is the inlet (d), and the other end of the seventh air duct (t) is connected with the air purifier (r). The air purifier (r) is also connected with one end of the sixth air duct (s), and the other end of the sixth air duct (s) is connected with the first interface (k1) described above. The air purifier (s) is also called an air cleaner, an air freshener, a purifier, etc., which refers to a product capable of adsorbing, decomposing or converting various air pollutants such as PM2.5, dust, pollen, odors, formaldehyde, etc. The application scenarios of the product mainly include household, commercial, industrial, and building. Various technologies can be applied in the air purifier (s), and common technologies include adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructure light mineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc. It also involves materials or equipment such as photocatalyst, activated carbon, synthetic fiber, HEPA high-efficiency material, and negative ion generator. Based on the above design, the air conditioner airflow first passes through the air purifier (s) and then is delivered from the sixth air duct (s) to the first interface (k1), ensuring the cleanliness of the air conditioner airflow.

[0070] Further, please refer to Figure 10 , the seventh air duct (t) includes a first bellows (t1), a first blow-molded air duct (t2), a second bellows (t3), and a second blow-molded air duct (t4). The first bellows (t1) is arranged at the bottom of the seat (a), and one end thereof is the inlet (d). The second bellows (t3) is arranged near the connection between the seat (a) and the back (b). The second blow-molded air duct (t4) is connected with the air purifier (r).

[0071] The bellows is a cylindrical thin-walled folded pipe with multiple transverse corrugations. The bellows has elasticity and can produce displacement under the action of pressure, axial force, lateral force, or bending moment. Therefore, based on the above design, when the seat moves forward and backward or the back (b) flips relative to the seat (a), the air duct (c) can also ensure the normal delivery of the air conditioner airflow. In a possible implementation, the two sides of the first bellows (t1) and the second bellows (t3) can also be provided with reinforcing strips, and the reinforcing strips are made of silica gel material and further provided with metal wires inside. Please refer to Figure 11 , which illustrates the top view and the side view of the first bellows (t1). Figure 11 The dashed line in Figure 11 represents the metal wires (t102) arranged inside the reinforcing strip (t101), and the reinforcing strip (t101) is a flat wing-shaped long strip. Through the above design, please refer to Figure 12Due to the reinforcing strip (t101) with the built-in metal wire (t102) on both sides, the metal wire (t102) can provide sufficient toughness, so that the first bellows (t1) and the second bellows (t3) will not affect the cross-sectional area even if they are bent with a large radius of rotation, further ensuring the normal delivery of air conditioning airflow. It should be noted that Figure 11 The manufacturing method of the first bellows (t1) shown in FIG. 1 can be injection molding. Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding method are fast production speed and high efficiency, operation can be automated, variety of colors and shapes, shape can be from simple to complex, size can be from large to small, product size is accurate, product is easy to update, can form complex parts, injection molding is suitable for mass production and complex shape products. The method is suitable for batch production of complex shaped parts. It is one of the important processing methods. By placing the metal wire (t102) in the corresponding position in the injection mold in advance, the first bellows (t1) shown in FIG. 1 can be obtained by one-piece injection molding. It should be understood that the structure and manufacturing method of the second bellows (t3) are similar to those of the first bellows (t1), which will not be described here. Figure 11

[0072] The other end of the aforementioned first outlet (e) can directly discharge the air conditioning airflow from the perforated skin at the back of the chair back (b), which means that the leather at the back of the chair back (b) has small holes that can ventilate and also bring a beautiful texture. Alternatively, please refer to Figure 13 The other end of the first outlet (e) can also be connected to the grille type air outlet device (u) provided at the back of the chair back (b) to discharge the air conditioning airflow from the grille type air outlet device (u). Alternatively, the above-mentioned grille type air outlet device (u) can also be replaced by an electric air outlet device, the difference lies in that the grille type air outlet device (u) needs to be manually adjusted, while the electric air outlet device can automatically adjust the air outlet direction.

[0073] The aforementioned second outlet (i) can directly discharge the air conditioning airflow from the perforated skin of the headrest (h), or please refer to Figure 14 The second outlet (i) can also be connected to the ring-shaped air outlet device (v) provided at the headrest (h) to discharge the air conditioning airflow from the ring-shaped air outlet device (v). Please refer to Figure 15 , Figure 15 The above-mentioned ring-shaped air outlet device (v) discharges air conditioning airflow, and the air conditioning airflow discharged by the ring-shaped air outlet device (v) to the occupant has the characteristics of low air pressure and comfortable touch.

[0074] ​Of course, the above-mentioned ring-shaped air outlet device (v) can also be replaced by a strip-shaped air outlet device with a width of 6 mm, and the air conditioning air flow discharged to the passenger also has the characteristics of low air pressure and comfortable touch.

[0075] The third outlet (j) can directly discharge the air conditioning air flow from the perforated skin at the front of the chair back (b).

[0076] It should be noted that in a possible implementation, the seat can also include the first air port (e), and in addition, one of the second outlet (i) and the third outlet (j). Correspondingly, the seat inside also does not need to be provided with the first control valve (k) and the second control valve (n) at the same time, but only needs to be provided with one control valve. Exemplarily, the control valve also includes three interfaces, namely interface 1, interface 2 and interface 3, the interface 1 is in communication with the inlet (d) of the air duct (c), the interface 2 is in communication with the first air port (e), and the interface 3 is in communication with one of the second outlet (i) and the third outlet (j).

[0077] Those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the system, device and unit described above can refer to the corresponding process in the foregoing method embodiments, which will not be repeated here.

[0078] In the several embodiments provided in the present application, it should be understood that the disclosed system, device and method can be implemented in other ways. For example, the device embodiments described above are only schematic. The division of the units is only a logical function division. There can be another division manner for actual implementation. For example, a plurality of units or components can be combined or integrated into another system, or some features can be ignored or not executed. In addition, the displayed or discussed mutual couplings or direct couplings or communication connections between the units can be indirect couplings or communication connections through some interfaces, devices or units, and can be electrical, mechanical or in other forms.

[0079] The units described as separate components can or can not be physically separate, and the components shown as units can or can not be physical units, that is, they can be located in one place, or can be distributed on a plurality of network units. Part or all of the units can be selected according to actual needs to achieve the purpose of the embodiment.

[0080] In addition, each functional unit in each embodiment of the present application can be integrated in one processing unit, or each unit can exist physically, or two or more units can be integrated in one unit. The above integrated unit can be realized in the form of hardware, or in the form of software functional unit.
