Description

Seat and vehicle Technical Field

[0001] The embodiments of the present application relate to the field of mechanical and electronic technology, and in particular to a seat and a vehicle. Background Art

[0002] In traditional passenger cars, in order to meet the cooling needs of rear passengers, air-conditioning vents are usually set on the rear side of the sub-dashboard.

[0003] However, due to the size of the sub-dashboard, the effective airflow area of ​​the air conditioning vents is limited, and the air flow is insufficient. Furthermore, if there are multiple rear passengers, the air conditioning vents cannot provide adequate airflow for all rear passengers. For example, if the air conditioning vents direct air to the left, they will not be able to cover the passengers in the middle and right seats.

[0018] In one possible implementation, the air duct further includes a first control valve disposed within the seat back. The first control valve includes a first port, a second port, and a third port. The air duct inlet communicates with the first port, the second port communicates with the first outlet, and the third port communicates with the second outlet and the third outlet. Under preset conditions, the first control valve is configured such that the first port communicates with at least one of the second port and the third port.

[0019] In the present application, by providing a first control valve, the discharge of the air-conditioning airflow from each outlet can be controlled.

[0020] In one possible implementation, the air duct further includes a second control valve, which includes a fourth interface, a fifth interface, and a sixth interface. The fourth interface communicates with the third interface, and the fifth and sixth interfaces communicate with the second outlet and the third outlet, respectively. The second control valve is configured under preset conditions so that the fourth interface communicates with at least one of the fifth and sixth interfaces. The preset conditions may be user instructions or vehicle control information, and at least one of the fifth and sixth interfaces may be either the fifth or sixth interface, or may include both interfaces.

[0059] The following describes the embodiments of the present application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. It is known to those skilled in the art that with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0060] The terms "first," "second," and the like in the specification and claims of this application and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to these processes, methods, products, or apparatus.

[0061] Current passenger cars are typically equipped with air conditioning systems to lower the interior temperature and provide a comfortable ride. A passenger car's air conditioning system consists of an air conditioning unit (AC) and multiple air outlets. The AC unit generates cool air, while the air outlets discharge it into the vehicle. As shown in Figure 1 , to meet the cooling needs of rear passengers, the vents are typically located behind the center console. However, the small size of the console limits the effective airflow area and airflow volume of these vents. Furthermore, since the console is typically located in the middle of the vehicle, when there are multiple rear passengers, the vents cannot provide adequate airflow for all passengers. For example, if the vents direct air to the left, they cannot reach passengers in the middle or right. Furthermore, for automakers, placing the vents behind the console limits storage space and presents various challenges in their specific structural design.

[0062] An embodiment of the present application provides a seat for providing better cooling or warm air blowing effects for passengers in a vehicle.

[0063] The seat in the embodiment of the present application can be set in the cabin of various vehicles, such as cars, airplanes, trains and ships, and an air conditioning box for generating air conditioning air is set in the above-mentioned vehicles. Referring to Figure 2, the seat in the embodiment of the present application includes a seat (a), a seat back (b) and an air duct (c). The air duct (c) includes an inlet (d) and a first outlet (e). The inlet (d) is set at the bottom of the seat (a) and is connected to the air supply duct (f) of the vehicle. The air supply duct (f) is also connected to the air conditioning system (g) of the vehicle and is used to transport the air conditioning air generated by the air conditioning system (g) to the inlet (d). The air conditioning air flow can be air conditioning cooling air or air conditioning heating air. The first outlet (e) is close to and faces the rear of the seat back (b), so that the air conditioning air flow can be discharged from the rear of the seat back (b). Based on the above design, the passengers located at the rear of the seat can be directly blown by the air conditioning air flow, and the rear area of ​​the seat is large, which can ensure sufficient air flow.

[0064] Based on the above, please refer to Figure 3. In one possible implementation, the seat further includes a headrest (h), and the air duct (c) further includes a second outlet (i) and a third outlet (j). The second outlet (i) is located at the headrest (h), thereby discharging the conditioned airflow from the headrest (h); the third outlet (j) is located close to and facing the front of the seatback (b), thereby discharging the conditioned airflow from the front of the seatback (b). It should be understood that the two wavy symbols shown in Figure 3 only indicate that the portion of the air duct (c) other than the second outlet (i) and the third outlet (j) has been omitted.

[0065] Please refer to Figure 4. In a possible implementation, the air duct (c) also includes a first control valve (k), a first air duct (l) and a second air duct (m) arranged inside the chair back (b). The first control valve (k) is provided with a first interface (k1), a second interface (k2) and a third interface (k3). A first flow guide device (k4) is also provided inside the first control valve (k). The first flow guide device (k4) includes a plurality of first wind shielding members (k5) distributed in the form of fan blades. One end of the first air duct (l) is an inlet (d), and the other end of the first air duct (l) is connected to the first interface (k1), thereby delivering the air-conditioning airflow to the first interface (k1). The second interface (k2) is connected to one end of the second air duct (m), and the other end of the second air duct (m) is a first outlet (e). The third interface (k3) is connected to the second outlet (i) and the third outlet (j). The first flow guide device (k4) is capable of rotating. When the plurality of first wind shields (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 third interface (k3), and the second interface (k2) are blocked; or, the first interface (k1), the second interface (k2), and the third interface (k3) are blocked. Taking FIG4 as an example, the plurality of first wind shields (k5) shown in FIG4 are located at a position that does not block the first interface (k1), the second interface (k2), and the third interface (k3). Alternatively, referring to FIG5, the first flow guide device (k4) is located at a position shown in FIG5 after being rotated 30 degrees clockwise based on the position shown in FIG4. It is not difficult to see that at this time, the positions of the multiple first wind shields (k5) do not block the first interface (k1), the second interface (k2), and the third interface (k3). Alternatively, please refer to Figure 6. After the first flow guide device (k4) is rotated 30 degrees counterclockwise based on the position shown in Figure 4, the position is as shown in Figure 6. It is not difficult to see that at this time, the positions of the multiple first wind shields (k5) do not block the first interface (k1), the second interface (k2), and the third interface (k3). Alternatively, please refer to Figure 7. After the first flow guide device (k4) is rotated 60 degrees clockwise based on the position shown in Figure 4, the position is as shown in Figure 7. It is not difficult to see that at this time, the positions of the multiple first wind shields (k5) do not block the first interface (k1), the second interface (k2), and the third interface (k3).

[0066] In a possible implementation, please refer to Figure 8a, the first windshield member (k5) is composed of a connecting rod (k501) and a windshield head (k502). The connecting rods (k501) of multiple first windshield members (k5) are connected to the same rotating shaft, and the position is switched under the drive of the rotating shaft. Since the connecting rod (k501) is small in size, it will not cause too much obstruction to the air conditioning airflow; the windshield heads (k502) of multiple first windshield members (k5) are used to block any number of air outlets in the first interface (k1), the second interface (k2) and the third interface (k3). Of course, Figure 8a shows only one implementation of the first windshield member (k5). The first windshield member (k5) can also be implemented in other forms, such as replacing the connecting rod (k501) with other connecting devices with air vents, or the shape of the windshield head (k502) can also be set in a different shape from that shown in Figure 8a. The details will not be repeated here.

[0067] 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) arranged inside the same chair back (b). Referring to Figure 8b, the second control valve (n) is provided with a fourth interface (n1), a fifth interface (n2), and a sixth interface (n3). A second flow guide device (n4) is also provided inside the second control valve (n), and the second flow guide device (n4) includes a plurality of second wind shields (n5) distributed in the form of fan blades. The two ends of the third air duct (o) are respectively connected to the third interface (k3) and the fourth interface (n1), and the air conditioning air flow 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 to one end of the fourth air duct (p), and one end of the sixth interface (n3) is connected to 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) is rotatable. When the plurality of second wind shielding members (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 sixth interface (n3), and the fifth interface (n2) are 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 above-mentioned introduction to the first control valve (k), and will not be repeated here.

[0068] In a possible implementation, please refer to Figure 8c, the second windshield (n5) is composed of a connecting rod (n501) and a windshield head (n502). The connecting rods (n501) of multiple second windshields (n5) are connected to the same rotating shaft, and the position is switched under the drive of the rotating shaft. Since the connecting rod (n501) is small in size, it will not cause too much obstruction to the air conditioning airflow; the windshield heads (n502) of multiple second windshields (n5) are used to block any number of air outlets in the fourth interface (n1), the third interface (n2) and the third interface (n3). Of course, Figure 8c shows only one implementation of the second windshield (n5). The second windshield (n5) can also be implemented in other forms, such as replacing the connecting rod (n501) with other connecting devices with air holes, or the shape of the windshield head (n502) can also be set in a different shape than that shown in Figure 8c. The specific details will not be repeated here.

[0069] By setting the first control valve (k) and the second control valve (n), after the air-conditioning airflow is delivered to the first interface (k1), it is possible to flexibly control whether the air-conditioning airflow can be discharged from the first outlet (e), the second outlet (i) and the third outlet (j).

[0070] In a possible implementation, please refer to Figure 9, the first air duct (l) may 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 an inlet (d), and the other end of the seventh air duct (t) is connected to the air purifier (r). The air purifier (r) is also connected to one end of the sixth air duct (s), and the other end of the sixth air duct (s) is connected to the aforementioned first interface (k1). The air purifier (s) is also called an air cleaner, air freshener and purifier, etc., which refers to a product that can adsorb, decompose or transform various air pollutants such as PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, and effectively improve the cleanliness of the air. Its application scenarios are mainly divided into household, commercial, industrial and building. Air purifiers (s) can employ a variety of different technologies, including adsorption, negative (positive) ionization, catalysis, photocatalysis, superstructured light mineralization, HEPA high-efficiency filtration, and electrostatic dust collection. Other technologies include photocatalysts, activated carbon, synthetic fibers, HEPA high-efficiency materials, and negative ion generators. Based on the aforementioned design, the air conditioning airflow first passes through the air purifier (s) and is then delivered to the first interface (k1) via the sixth air duct (s), ensuring the cleanliness of the air conditioning airflow.

[0071] Furthermore, referring to Figure 10, the seventh air duct (t) includes a first bellows (t1), a first blown air duct (t2), a second bellows (t3), and a second blown air duct (t4). The first bellows (t1) is located at the bottom of the seat (a), with one end thereof serving as an inlet (d); the second bellows (t3) is located near the connection between the seat (a) and the backrest (b); and the second blown air duct (t4) is connected to the air purifier (r).

[0072] A bellows is a cylindrical, thin-walled, corrugated pipe with multiple transverse corrugations. The bellows is elastic and can be displaced under pressure, axial force, transverse force, or bending moment. Therefore, based on the above design, when the seat moves forward and backward or the backrest (b) flips relative to the seat (a), the air duct (c) can also ensure the normal delivery of air-conditioning air. In a possible implementation, reinforcement strips can be provided on both sides of the first bellows (t1) and the second bellows (t3). The material of the reinforcement strips is silicone, and metal wires are also provided inside the reinforcement strips. Please refer to Figure 11, which takes the first bellows (t1) as an example for explanation. Figure 11 shows a top view and a side view of the first bellows (t1). The dotted line in Figure 11 represents the metal wire (t102) provided inside the reinforcement strip (t101). The reinforcement strip (t101) is a flat, wing-shaped strip. With the above design, please refer to Figure 12. Due to the reinforcement strips (t101) with built-in metal wires (t102) on both sides, the metal wires (t102) can provide sufficient toughness, so that even if the first bellows (t1) and the second bellows (t3) are bent with a large turning radius, the cross-sectional area will not be affected, further ensuring the normal transmission of the air conditioning airflow. It should be noted that the manufacturing method of the first bellows (t1) shown in Figure 11 can be injection molding, which is also known as injection molding. It is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed and high efficiency, automated operation, a wide variety of colors and patterns, shapes from simple to complex, sizes from large to small, and precise product dimensions. The product is easy to update and can be made into complex-shaped parts. Injection molding is suitable for mass production and molding processing fields such as complex-shaped products. At a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, and cooled and solidified to obtain a molded product. This method is suitable for mass production of complex-shaped parts and is one of the important processing methods. By placing the metal wire (t102) in the corresponding position in the injection mold in advance and then performing integral injection molding, the first bellows (t1) shown in Figure 11 can be obtained. It should be understood that the structure and manufacturing method of the second bellows (t3) are similar to those of the first bellows (t1) and will not be described again here.

[0073] The other end of the aforementioned first outlet (e) can directly discharge the air-conditioning airflow from the perforated leather at the rear of the chair back (b). Perforated leather refers to the leather at the rear of the chair back (b) having small holes that allow air to pass through, while also providing an aesthetically pleasing texture. Alternatively, referring to FIG13 , the other end of the first outlet (e) can also be connected to a grille-type air outlet device (u) provided at the rear of the chair back (b) to discharge the air-conditioning airflow from the grille-type air outlet device (u). Alternatively, the aforementioned grille-type air outlet device (u) can also be replaced with an electric air outlet device. The difference is that the grille-type air outlet device (u) requires manual adjustment of the air outlet direction, while the electric air outlet device can automatically adjust the air outlet direction.

[0074] The aforementioned second outlet (i) can directly discharge the conditioned airflow through the perforated cover of the headrest (h). Alternatively, as shown in Figure 14, the second outlet (i) can also be connected to an annular air outlet device (v) provided on the headrest (h), discharging the conditioned airflow through the annular air outlet device (v). Figure 15 shows a schematic diagram of the conditioned airflow discharged from the annular air outlet device (v). The conditioned airflow discharged toward the occupant by the annular air outlet device (v) has low pressure and a comfortable feel.

[0075] Of course, the annular air outlet device (v) can also be replaced by a strip-shaped air outlet device. The width of the strip-shaped air outlet device is 6 mm, and the air-conditioning airflow discharged to the passengers also has the characteristics of low wind pressure and comfortable touch.

[0076] The third outlet (j) can directly discharge the air-conditioned air from the perforated leather at the front of the seat back (b).

[0077] It should be noted that, in a possible implementation, the seat may also include a first air outlet (e), in addition to one of a second outlet (i) and a third outlet (j). Correspondingly, the seat does not need to be provided with both a first control valve (k) and a 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. Interface 1 is connected to the inlet (d) of the air duct (c), interface 2 is connected to the first air outlet (e), and interface 3 is connected to one of the second outlet (i) and the third outlet (j).

[0078] Those skilled in the art will clearly understand that, for the convenience and brevity of description, the specific working processes of the systems, devices and units described above can refer to the corresponding processes in the aforementioned method embodiments and will not be repeated here.

[0079] In the several embodiments provided in this application, it should be understood that the disclosed systems, devices and methods can be implemented in other ways. For example, the device embodiments described above are merely schematic. For example, the division of the units is merely a logical function division. In actual implementation, there may be other division methods, such as multiple units or components can be combined or integrated into another system, or some features can be ignored or not executed. Another point is that the mutual coupling or direct coupling or communication connection shown or discussed can be an indirect coupling or communication connection through some interfaces, devices or units, which can be electrical, mechanical or other forms.

[0080] The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units, that is, they may be located in one place or distributed across multiple network units. Some or all of these units may be selected to achieve the purpose of this embodiment according to actual needs.

[0081] In addition, the functional units in the various embodiments of the present application may be integrated into a single processing unit, or each unit may exist physically separately, or two or more units may be integrated into a single unit. The aforementioned integrated units may be implemented in the form of hardware or software functional units.
