Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to an air circulation structure, a seat assembly, and a vehicle. Background Technology

[0002] In hot weather, some users want the seat to quickly dissipate heat using a blowing mode; while in humid environments or after long periods of sitting, some users want the seat to keep the surface dry and comfortable using a suction mode. To address this, related technologies provide a combined fan that integrates an axial fan and a centrifugal fan in the same housing. By controlling the operation of the axial fan or the centrifugal fan, the combined fan can be set to suction or blowing mode.

[0003] However, the housing design results in the combined fan occupying a large volume. When the seat support of the seat assembly is thin, passengers may feel a foreign object sensation caused by the combined fan when leaning against the seat. In order to eliminate the foreign object sensation, the overall thickness of the seat needs to be increased, which leads to an increase in the volume occupied by the seat assembly.

[0004] Therefore, there is an urgent need for a seat assembly to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an air circulation structure, a seat assembly, and a vehicle that can reduce the thickness of the seat support, reduce the feeling of foreign objects when passengers lean against it, and thus improve the comfort of the seat assembly.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The first aspect provides an air circulation structure, including a first fan, a second fan, and an air duct. The air duct is located between the first fan and the second fan, and the first fan and the second fan are connected through the air duct. The air duct is a structure that can deform along the direction of fan movement. Of the first fan and the second fan, one is a blowing fan and the other is a suction fan.

[0008] As an optional technical solution for the above-mentioned air circulation structure, the air duct includes a deformable part and two connecting parts. Each end of the deformable part is provided with a connecting part, and the deformable part is connected to the connecting parts. Of the two connecting parts, one is connected to the first fan and the other is connected to the second fan.

[0009] As an optional technical solution for the above-mentioned air circulation structure, the deformable part has at least one deformable unit, and the plane passing through the central axis of the air duct is set as a preset plane, and the shape of the deformable unit in the preset plane is V-shaped or U-shaped.

[0010] As an optional technical solution for the aforementioned air circulation structure, the air duct includes a flexible hose.

[0011] Secondly, a seat assembly is provided, comprising:

[0012] skeleton;

[0013] In the air circulation structure described in any of the above embodiments, the first fan and the second fan are respectively disposed on both sides of the frame, and the air duct passes through the frame and connects the first fan and the second fan.

[0014] As an optional technical solution for the above-mentioned seat assembly, the seat assembly further includes a seat support body installed on one side of the frame. The seat support body is provided with a mounting groove, and one of the first fan and the second fan is installed in the mounting groove, while the other is installed on the frame.

[0015] As an optional technical solution for the above-mentioned seat assembly, the seat assembly further includes a seat support body installed on one side of the frame, the first fan is a blower fan, the first fan is disposed on the side of the frame facing the seat support body, and an isolation member is disposed between the frame and the first fan, the isolation member being used to seal and isolate the air generated by the first fan from the side of the frame facing the seat support body.

[0016] As an optional technical solution for the above-mentioned seat assembly, the seat assembly further includes a seat back panel installed on the other side of the frame, the seat support has ventilation holes, the isolation member has a sealing layer and a mesh layer, the sealing layer is disposed on the side of the mesh layer facing the seat back panel, the sealing layer has a through hole for the air duct to pass through, and the mesh layer communicates with the ventilation holes.

[0017] As an optional technical solution for the aforementioned seat assembly, the seat assembly further includes a fixing plate, which is mounted on the seat support and connected to the first fan.

[0018] Thirdly, a vehicle is provided, including the seat assembly or the air circulation structure described in any of the above embodiments.

[0019] This utility model has at least the following beneficial effects:

[0020] The air circulation structure provided by this utility model has an air duct that can deform along the direction of fan movement. Under the action of external force, the air duct can be compressed and shortened. The air duct is located between the first fan and the second fan, so the overall volume of the air circulation structure is reduced. The first fan can move towards the air duct. When the passenger leans against the seat, the seat deforms and the first fan moves towards the air duct. In this way, the air circulation structure will move relative to the passenger, thereby reducing the feeling of foreign objects when the passenger leans against it and improving the passenger's riding experience.

[0021] The seat assembly and vehicle provided by this utility model have a first fan installed in a mounting slot and a second fan installed on the side of the seat back facing the seat support. This reduces the space occupied by the air circulation structure in the seat support and the thickness of the seat support, thereby reducing the manufacturing cost of the seat support. When a passenger leans against the seat, the seat support is compressed. The deformation of the seat support will transfer the compressive force to the first fan and the air duct. The air duct deforms after being compressed, causing the first fan to move, thereby reducing the foreign body sensation caused by the passenger leaning against the seat. In addition, one of the first fan and the second fan is a blowing fan and the other is a suction fan. This can keep the surface of the seat assembly dry or quickly dissipate the stuffiness as needed, thereby improving passenger comfort. Attached Figure Description

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and 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 utility model based on the specific circumstances.

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] like Figures 1 to 7 As shown, this utility model provides an air circulation structure and a seat assembly. The air circulation structure can be reduced in volume under external force to allow relative movement with the passenger, reducing the feeling of foreign objects when the passenger leans against it while achieving both air intake and air blowing. This seat assembly can reduce the thickness of the seat support 3, further reducing the feeling of foreign objects when the passenger leans against it, thereby improving the comfort of the seat assembly.

[0036] like Figures 1 to 5 As shown, the air circulation structure 4 includes a first fan 41, a second fan 43 and an air duct 42. The air duct 42 is located between the first fan 41 and the second fan 43, and the first fan 41 and the second fan 43 are connected through the air duct 42. The air duct 42 is a structure that can deform along the direction of fan movement. Of the first fan 41 and the second fan 43, one is a blowing fan and the other is a suction fan.

[0037] Since the air duct 42 can deform along the direction of fan movement, it can be compressed and shortened under the action of external force. Since the air duct 42 is located between the first fan 41 and the second fan 43, the overall volume of the air circulation structure 4 will be reduced. The first fan 41 can move towards the air duct 42. When the passenger leans against the seat, the first fan 41 will move towards the air duct 42 after the seat is deformed. In this way, the air circulation structure 4 will move relative to the passenger, thereby reducing the feeling of foreign objects when the passenger leans against it and improving the passenger's riding experience.

[0038] In some embodiments, the air duct 42 includes a flexible hose that can be bent and deformed under external force and return to its original shape after the external force is removed. In this way, the hose can absorb the leaning force applied by the passenger and provide space for the first fan 41 or the second fan 43 to move backward.

[0039] Specifically, such as Figure 3As shown, the air duct 42 includes a deformable part 421 and two connecting parts 422. Each end of the deformable part 421 is provided with a connecting part 422. The deformable part 421 communicates with the two connecting parts 422. One of the two connecting parts 422 is connected to the first fan 41 and the other is connected to the second fan 43. The connecting part 422 is used to connect with the first fan 41 and the second fan 43, while the deformable part 421 is used to absorb the leaning force applied by the passenger, so that the positions of the first fan 41 and the second fan 43 are relatively moved, so as to reduce the discomfort of the passenger being pressed by the air circulation structure 4 after sitting, reduce the feeling of foreign objects, and improve the passenger's riding comfort.

[0040] For example, the deformable part 421 has at least one deformable unit, and the plane passing through the central axis of the air duct 42 is set as a preset plane. The shape of the deformable unit in the preset plane is V-shaped or U-shaped. The V-shape or U-shape can provide deformation space for the deformable part 421, so that the two connecting parts 422 can move closer to each other under the action of external force to reduce the volume of the air circulation structure 4. The deformable part 421 can guide the gas while providing space for the first fan 41 to move backward.

[0041] It is understandable that when there is only one deformation unit, the shape of the deformation unit in the preset plane is V-shaped or U-shaped. When there are two or more deformation units, all deformation units can be V-shaped, all deformation units can be U-shaped, or some deformation units can be V-shaped and some deformation units can be U-shaped.

[0042] Of course, in some other embodiments, the air duct 42 includes a bellows that can deform and be stretched under the action of an external force, so that the first fan 41 can move away from the passenger when the passenger leans against it, thereby reducing the foreign body sensation caused by the passenger leaning against the seat assembly. When the force applied by the passenger disappears, the first fan 41 pulls the air duct 42 back to its original position. The connection between the first fan 41 and the air duct 42 enables the air duct 42 to be stretched to return to its original position.

[0043] In some embodiments, both the first fan 41 and the second fan 43 abut against the air duct 42 to achieve communication. That is, the air duct 42 is clamped by the first fan 41 and the second fan 43, which move closer together to compress the air duct 42. This ensures that the air duct 42 always tends to return to its original position, guaranteeing that the air duct 42 remains in close contact with the first fan 41 and the second fan 43. Of course, the first fan 41 and the second fan 43 are fixedly connected to the air duct 42. For example, the air duct 42 and the first fan 41 and the second fan 43 can be fixedly connected by adhesive or by fasteners.

[0044] The air circulation structure 4 provided by this utility model has a blowing mode and a suction mode, and the purpose of blowing and suction is achieved by switching modes.

[0045] For example, the first fan 41 is a blowing fan, and the second fan 43 is a suction fan. The first fan 41 and the second fan 43 are connected by an air duct 42 to form an airflow path. The two fans, the first fan 41 and the second fan 43, can switch between blowing and suction modes. Through the integrated blowing and suction design and the realization of the independent operation function of the two fans, users can independently select the suction mode or blowing mode of the seat, meeting the ventilation needs of different environments and user preferences, greatly improving the comfort of the seat. This structure can achieve both rapid cooling through suction and the feel of blowing air, satisfying the diverse needs of users.

[0046] like Figure 4 As shown, when the blowing mode is activated, the first fan 41 operates, while the second fan 43 remains inactive. Airflow passes through the first fan 41 from the outside of the seat to the inside, thus achieving the blowing function. Figure 5 As shown, when the suction mode is activated, the second fan 43 works while the first fan 41 does not work. The airflow flows from the inside of the seat to the outside of the seat through the second fan 43, thus achieving the suction function.

[0047] In addition, this utility model also provides a seat assembly, such as Figure 6 and Figure 7 As shown, the seat assembly includes a frame 1 and an air circulation structure 4 provided in this embodiment of the invention. The seat back panel 2 and the seat support 3 are both mounted on the frame 1. The seat back panel 2 is mounted on one side of the frame 1, while the seat support 3 is mounted on the other side of the frame 1. Figure 6 and Figure 7 As shown, the first fan 41 and the second fan 43 are respectively disposed on both sides of the frame 1, and the air duct 42 passes through the frame 1 and connects the first fan 41 and the second fan 43.

[0048] The seat assembly provided by this utility model has a first fan 41 and a second fan 43 located on both sides of the frame 1. The air duct 42 can deform along the direction of fan movement, thus reducing the space occupied by the air circulation structure 4 in the seat support 3 and reducing the thickness of the seat support 3, thereby reducing the manufacturing cost of the seat support 3. When the passenger leans against the seat, it will squeeze the first fan 41 and the air duct 42. The air duct 42 can deform along the direction of fan movement, causing the first fan 41 to move in position, so as to reduce the foreign body sensation caused by the passenger leaning against the seat. In addition, one of the first fan 41 and the second fan 43 is a blowing fan and the other is a suction fan, so that the surface of the seat assembly can be kept dry or the stuffy feeling can be quickly dissipated as needed, thereby improving the comfort of the passenger.

[0049] It is understandable that the first fan 41 and the second fan 43 are located on both sides of the frame 1. Since the air duct 42 connects the first fan 41 and the second fan 43, the frame 1 has a through hole for the air duct 42 to pass through, so as to avoid interference between the frame 1 and the air duct 42 and achieve the purpose of connecting the first fan 41 and the second fan 43 by the air duct 42.

[0050] In some embodiments, the seat assembly further includes a seat support 3 disposed on one side of the frame 1. The seat support 3 is provided with a mounting groove. Of the first fan 41 and the second fan 43, one is installed in the mounting groove, while the other is installed on the side of the frame 1 away from the seat support 3. The mounting groove can provide accommodating space for the first fan 41 or the second fan 43, and the mounting groove can further reduce the overall thickness of the seat assembly.

[0051] For example, the seat support 3 is a foam structure, and the seat support 3 is provided with ventilation holes 31. The ventilation holes 31 can guide the airflow on both sides of the seat support 3 so that the airflow enters or flows out through the ventilation holes 31.

[0052] The air circulation structure 4 is installed on the seat support 3. The air duct 42, including the hose, takes into account the limited internal space and usage characteristics of the seat. The combination of the first fan 41, the second fan 43 and the air duct 42 allows it to adapt to different adjustment movements of the seat and will not affect the ventilation function due to changes in the shape of the seat.

[0053] The seat assembly also includes a seat back panel 2 located on the other side of the frame 1. The first fan 41 is a blower fan, which increases the airflow generated by the first fan 41 out of the seat support 3. In order to allow more air blown by the first fan 41 to flow out of the seat support 3 and not leak from the seat back panel 2, refer to 6 and... Figure 7 In some embodiments, the first fan 41 is disposed on the side of the frame 1 facing the seat support 3, and an isolation member 5 is disposed between the frame 1 and the seat support 3. The isolation member 5 is used to seal and isolate the wind generated by the first fan 41 on the side of the frame 1 facing the seat support 3. That is, the isolation member 5 can block the wind generated by the first fan 41, so that as much wind generated by the first fan 41 as possible flows out through the seat support 3.

[0054] In addition, to increase the air volume, the seat support 3 has multiple ventilation holes 31, which can provide guidance and passage for air. Specifically, in order to fix the isolation member 5 to the air duct 42, the isolation member 5 and the air duct 42 can be fixedly connected by adhesive bonding.

[0055] For example, the spacer 5 is partially located in the mounting groove, and the portion of the spacer 5 located in the mounting groove is bonded to the side wall of the mounting groove.

[0056] Specifically, such as Figure 6 As shown, the isolation member 5 has a sealing layer 51 and a mesh layer 52. The sealing layer 51 is disposed on the side of the mesh layer 52 facing the seat back panel 2. The sealing layer 51 has a through hole for the air duct 42 to pass through. Specifically, the upper part of the sealing layer 51 is fixedly connected to the seat support 3 to fix the sealing layer 51. Of course, in other embodiments, the sealing layer 51 can also be connected to the frame 1. One end of the air duct 42 passes through the sealing layer 51 and abuts against the first fan 41, while the other end of the air duct 42 abuts against the second fan 43. It can be understood that the air duct 42 passes through the through hole of the sealing layer 51 and is press-fitted to the sealing layer 51 so that one end of the air duct 42 is inserted into the sealing layer 51. This can both connect the air duct 42 to the isolation member 5 and seal the air generated by the first fan 41 to prevent leakage, thus preventing the airflow from going towards the seat back panel 2 and increasing the airflow towards the seat support 3.

[0057] In some embodiments, combined with Figure 6 and Figure 7 As shown, the seat assembly also includes a fixing plate 6, which is installed on the seat support 3. For example, the fixing plate 6 is embedded or pasted on the side of the seat support 3 facing the seat back panel 2. The fixing plate 6 is connected to the first fan 41 to provide a mounting support point for the first fan 41.

[0058] Furthermore, the fixing plate 6 is located within the mounting groove of the seat support 3. Specifically, the fixing plate 6 is installed on the groove wall away from the seat back panel 2. The fixing plate 6 has mounting holes to facilitate the installation of the first fan 41. The fixing plate 6 provides a mounting point for the first fan 41, preventing the first fan 41 from being directly connected to the seat support 3 and causing the first fan 41 to separate from the seat support 3 due to an unstable connection point.

[0059] In some embodiments, the seat assembly further includes a first resilient fastener 7, through which the first fan 41 is fixed to the mounting plate 6. The first resilient fastener 7 passes through a mounting hole in the mounting plate 6 and is embedded in the seat support 3. For example, the first resilient fastener 7 includes a rubber nail.

[0060] In some embodiments, the seat assembly further includes a second resilient fastener 8, by which the second fan 43 is secured to the side of the seat back panel 2 facing the seat support 3. For example, the second resilient fastener 8 includes a rubber stud.

[0061] Specifically, the first elastic fastener 7 and the fixing plate 6 are both pre-embedded or pasted into the seat support 3. The first fan 41 is fixedly connected by the first elastic fastener 7 and the fixing plate 6. The second elastic fastener 8 passes through the second fan 43 and is installed on the sheet metal of the frame 1 and is set towards the seat back panel 2.

[0062] The isolation component 5, the first fan 41, and the second fan 43 work together to ensure that the airflow can flow smoothly and efficiently within the air circulation structure 4, resulting in high ventilation efficiency and good stability.

[0063] The seat assembly provided by this utility model can realize both blowing and suction. Users can choose to blow or suction according to their needs to meet different scenarios. It is easy to install, and the air circulation structure is lightweight and small in size.

[0064] The seat assembly is assembled as follows:

[0065] First, the first elastic fastener 7 and the fixing plate 6 are pre-embedded or glued in the seat support body 3. Then, the first fan 41 is installed to the seat support body 3 through the first elastic fastener 7. After sealing the first fan 41 and the isolation part 5 through the sealing layer 51 on the isolation part 5, it is then attached to the corresponding mounting groove on the seat support body 3. Then, the air duct 42 passes through the sealing layer 51 of the isolation part 5 and is connected to the blower fan. Then, the seat support body 3 with the first fan 41 assembled is installed on the frame 1. Then, the second elastic fastener 8 is installed on the sheet metal of the frame 1. Then, the second fan 43 is installed on the seat back panel 2 through the second elastic fastener 8. Finally, the seat back panel 2 is fastened to the frame 1 to fix the seat back panel 2 and the frame 1.

[0066] This utility model also provides a vehicle, including the seat assembly or the air circulation structure provided in the embodiments of this utility model.

[0067] The vehicle also includes a chassis, with the seat assembly mounted on top of the chassis for support, and the chassis enabling the seat assembly to move.

[0068] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
