DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] Example 1

[0035] Please refer to Figure 1 , Figure 2 and Fig.10 , the present application provides a ventilation element, comprising:

[0036] An air guide layer 1, wherein the air guide layer 1 has an air source side 2 and an air guide side 3 arranged opposite to the air source side 2, the air guide layer 1 is wrapped with a sealing layer 4 on the outside, the sealing layer 4 is provided with an air source port 5 for connecting to the air port of the fan 12 on the air source side 2, and an air guide port 6 on the air guide side 3;

[0037] The hanging body 7 includes a mounting seat 71 and a mounting rod 72. The mounting seat 71 is arranged on the wind source side 2 and is fixedly connected to the side of the sealing layer 4 away from the wind guide layer 1. The mounting rod 72 is detachably connected to the mounting seat 71 and is used to connect the fan 12.

[0038] Specifically, the fan 12 can realize a blowing mode or a suction mode. When the air inlet of the fan 12 is connected to the air source port 5, the fan 12 cooperates with the seat ventilation to realize that the air on the seat surface is sucked into the fan through the air guide layer and then discharged into the vehicle cabin through the air outlet of the fan 12. This is called the suction mode. Fig. 9 and Fig.13 When the air outlet of the fan 12 is connected to the air source port 5, the air in the vehicle cabin is sucked in by the air inlet of the fan 12, enters the air guide layer 1 through the air source port 5, and then blows toward the seat surface of the car seat, which is called the blowing mode. Fig.12 In this embodiment, the fan 12 is a blowing type fan 12, which can realize the blowing mode. In a certain embodiment, please refer to Fig. 9 The fan 12 can also be a suction type fan 12, which can realize the suction mode. When the fan 12 is of the suction type, the air outlet position of the fan 12 changes, and the position of the wind source port 5 is adjusted corresponding to the air outlet position of the suction type fan 12.

[0039] Specifically, in a certain embodiment, the material of the sealing layer 4 can be plastic, rubber, metal or the like, and commonly used are PET film, non-woven fabric or both. The connection method between the mounting seat 71 and the sealing layer 4 can be selected according to the material of the sealing layer, and can be fixed by gluing, hot-melt welding, bolts or snaps.

[0040] Specifically, the mounting rod 72 is disposed perpendicular to the surface of the sealing layer 4 on which the mounting seat 71 is mounted, and is detachably connected to a side of the mounting seat 71 away from the sealing layer 4 .

[0041] Specifically, an adhesive layer 11 is provided on the sealing layer 4 located on the air guide side 3. By providing the adhesive layer 11, it is convenient to be attached and connected with other components, such as Fig.13 As shown, the air guide layer 1 is fixedly and sealedly connected to the seat foam 9 via the adhesive layer 11 .

[0042] Specifically, the air guide ports 6 are arranged in a plurality on the air guide side 3. By providing a plurality of the air guide ports 6, the ventilation effect is enhanced. By optimizing the position of the air guide ports 6, the air flow at a specific position can be guided. The sealing layer 4 is provided with ventilation holes corresponding to the air guide ports 6 and the wind source port 5. By reasonably arranging the air guide ports 6, the wind sensing area of ​​the entire seat surface can be reasonably arranged. Figure 4 , Fig.12 and Fig.13 shown.

[0043] Working principle: A sealing layer 4 is wrapped around the outside of the air guide layer 1, and the sealing layer 4 is provided with an air source port 5 and an air guide port 6. The fan 12 blows air from the air source port 5, and generates air flow at the air guide port 6 to achieve ventilation. The hanging body 7 is provided, and the hanging body 7 includes a mounting seat 71 and a mounting rod 72. The mounting seat 71 is fixedly connected to the side of the sealing layer 4 away from the air guide layer 1. The volume of the mounting seat 71 is very small compared to the volume of the entire hanging body 7. The sealing layer 4 does not need to have a hole. Since all the connections are operated outside the air guide layer 1, it is not affected by the air guide layer 1, and the operation is simple and convenient. Moreover, the mounting base 71 is relatively small in size, and the sealing layer 71 has little impact on subsequent transportation and packaging after installation; the mounting rod 72 can be detachably mounted on the mounting base 71, so that the fan 12 can be easily installed, and when the fan needs to be replaced, only the mounting rod 72 needs to be removed, and the operation is relatively simple; at the same time, since the mounting base 71 and the mounting rod 72 are detachably connected, when the mounting rod 72 is broken due to long-term vibration of the seat, the ventilation element can be repaired by replacing only the mounting rod 72, without replacing the entire suspension body 7, thereby saving maintenance costs and increasing the service life of the suspension body 7.

[0044] In one embodiment, please refer to Fig.11 , the sealing layer 4 can also be set to only wrap around the wind source side 2 of the wind guide layer 1. In this case, the entire wind guide side 3 of the wind guide layer 1 serves as the wind guide port 6. The advantages of this ventilation element are simple production process and low production cost. Since the hanging body 7 is made in a split type, and the volume of the mounting seat 71 is very small compared to the volume of the hanging body 7, a hole can be opened on the sealing layer 4, such as Fig.11 As shown, the base area of ​​the mounting seat 71 is larger than the size of the opening on the sealing layer 4, the size of the support portion 711 is smaller than the size of the opening on the sealing layer 4, the mounting seat 71 is fixed to the side of the sealing layer 4 away from the fan 12 by gluing or hot-melt welding, and the support portion 711 passes through the opening of the sealing layer 4. Since the size of the mounting seat 71 is much smaller than the size of the hanging body 7, it is little affected by the air guide layer 1, has operability, and does not affect subsequent processing and transportation.

[0045] For further information, please refer to Figure 2 A support portion 711 is provided on the mounting seat 71, and one end of the mounting rod 72 is detachably connected to the support portion 711, so that the sealing layer 4 will not be affected when installing and removing the mounting rod 72, which is convenient for operation; the mounting rod 72 has a plug-in section 721 and a mounting section 722, and the mounting section 722 is arranged close to the mounting seat 71 for installing and fixing the fan 12. The plug-in section is located at one end of the mounting section 722 away from the mounting seat 71, and is used to guide the installation of the mounting rod 72 and the fan 12, or serve as an installation support portion of the mounting rod 72 (i.e., the portion clamped by hands or tools).

[0046] Furthermore, the support portion 711 is arranged on a side of the mounting seat 71 away from the sealing layer 4, the support portion 711 is cylindrical and hollow inside, one side of the support portion 711 is provided with an opening connected to the inside, the cylindrical support portion 711 allows a certain interval between the fan 12 and the sealing layer 4 after installation, which can be used to place sheet metal parts or suspension springs to prevent the fan 12 from colliding with the seat support frame, and the hollow interior reduces the structural weight of the suspension body 7 and the burden on the wind guide layer 1; the end face of the support portion 711 away from the mounting seat 71 is provided with a snap-in groove 7111, the snap-in groove 7111 is connected to the inside of the support portion 711, the snap-in groove 7111 is circular and close to the seat support frame. A cutout 7112 is provided on one side near the opening, and the width of the cutout 7112 is smaller than the diameter of the snap-in groove 7111. A snap-in portion 723 is provided at the end of the mounting rod 72 near the mounting section 722. The snap-in portion 723 has diameters at both ends that are larger than the diameter of the middle portion, and the diameter of the middle portion matches the snap-in groove 7111. When in use, the middle portion of the snap-in portion 723 is snapped into the snap-in groove 7111 through the cutout 7112. Since the diameters at both ends of the snap-in portion 723 are larger, the mounting rod 72 is not easy to fall off from the snap-in groove 7111. At the same time, no other auxiliary parts are required for fixing during connection, which makes disassembly convenient and the mounting rod 72 easy to replace.

[0047] Furthermore, the mounting seat 71 and the mounting rod 72 may be made of the same material or different materials. In a certain embodiment, the mounting seat 71 is made of a non-deformable plastic material, such as PC, PA, ABS or reinforced with glass fiber, and the mounting rod 72 may be made of the above materials. The mounting rod 72 made of the above materials has high structural strength and is not easily damaged, thereby increasing the service life. The mounting rod 72 may also be made of a soft elastic material, such as a rubber material or a silicone material. The mounting rod 72 made of a rubber material or a silicone material may deform when subjected to force, thereby achieving a good shock absorption effect, thereby reducing the vibration transmitted by the fan 12 during operation and affecting the use effect. Of course, the mounting seat 71 may also be made of a soft elastic material.

[0048] Furthermore, when the mounting rod 72 is made of soft elastic material, such as rubber material or silicone material, the requirements for installation conditions are more tolerant. When installed on the seat, when the seat is deformed under force, the mounting rod 72 can follow the shape change. The mounting rod 72 can be compatible with changes in some dimensions to avoid breakage due to stress concentration.

[0049] For further information, please refer to Figure 2 and Figure 6, limiting portions 724 are respectively provided on the side walls at both ends of the mounting section 722, and the limiting portions 724 are columnar and the diameter gradually decreases from the end away from the plug-in section 721 to the end close to the plug-in section 721 to form a guide surface, so that it is convenient for the fan 12 to transition from the plug-in section 721 to the mounting section 722, and the fan 12 is clamped and fixed to the mounting section 722; the limiting portion 724 is preferably made of rubber or silicone, so that it is deformed when the mounting portion 121 of the fan 12 is inserted, and after the fan 12 enters the mounting section 722, the limiting portion 724 restores its deformation so that the fan 12 is clamped in the mounting section 722.

[0050] For further information, please refer to Figure 7 The mounting rod 72 can also be configured in different shapes to accommodate different types of fans 12. Figure 8 How different types of hanging bodies 7 are connected to the mounting parts 121 of other types of fans 12 will not be described in detail here. Figure 7 The mounting rod 72 and Figure 8 The installation part 121 in is not a corresponding relationship.

[0051] Furthermore, the hanging bodies 7 may be provided with a plurality of them on the sealing layer 4, and the adjacent hanging bodies 7 are connected by connecting rods 8 to form a hanging body assembly. In a certain embodiment, as shown in FIG3 , three hanging bodies 7 are provided, and the fan is fixed by three hanging bodies 7 so that the fixing effect is stronger. The structural strength between the hanging bodies 7 is stronger by providing the connecting rods 8, so as to prevent the stability of the fan 12 from being affected by the separation of one of the hanging bodies 7 from the sealing layer 4. Moreover, the three hanging bodies 7 are connected together and can be operated together, which can relatively reduce the number of assembly steps.

[0052] Example 2

[0053] Please refer to Figure 1 The present application provides a ventilation element, including a fan 12 and the ventilation element as described above, wherein the mounting rod 72 is engaged with the fan 12. The ventilation system can achieve the purpose of ventilation through the cooperation between the fan 12 and the ventilation element.

[0054] Example 3

[0055] Please refer to Figure 4 and Figure 5The present application provides a ventilated seat, comprising a seat cover, a seat foam 9, a support frame 10 and the ventilation element as described above, wherein the seat cover is placed on the side of the seat foam 9 close to the human body, the ventilation element is installed between the seat foam 9 and the support frame 10, and is connected to the bottom of the seat foam 9 through the adhesive layer 11, the fan 12 is located on the side of the support frame 10 away from the seat foam 9, the support frame 10 is provided with a through hole or a gap formed between steel wires corresponding to the hanging body 7, and the hanging body 7 is connected to the fan 12 across the through hole or the steel wire gap on the support frame 10.

[0056] Of course, if Figure 5 As shown, when there is no support frame 10 to fix the fan 12 and the air guide layer 1 at the connection position, the hanging body 7 can also fix the fan 12 without crossing the through hole or the gap between the steel wires.

[0057] The ventilation element is fixed to the seat foam 9 by the support frame 10, and the seat can be ventilated by the ventilation effect of the ventilation element; please refer to Fig.12 and Fig.13 The ventilation elements are respectively arranged at the bottom and the back of the seat, and the seat foam 9 is provided with a plurality of ventilation holes corresponding to the air guide port 6. The ventilation holes are provided to improve the ventilation efficiency of the seat.
