Description

Technical Field

[0001] The present application relates to the field of vehicle ventilation technology, and in particular to a porous distributed closed installation structure of a vehicle seat ventilation system and a vehicle seat. Background Art

[0002] As people's requirements for riding comfort continue to increase, seat ventilation systems have been widely used in various types of seats. However, there are many technical problems in arranging ventilation systems for seats.

[0003] On the one hand, the air bag is fixed in a single way, relying too much on double-sided tape for installation. This installation method often results in loose adhesion, especially in extreme positions, and cannot achieve effective sealing. This not only affects the stability of the ventilation system, but may also cause problems such as air leakage, reducing the ventilation effect.

[0004] On the other hand, during the assembly of the vents and the foam, due to tolerances, the vents often fail to be perfectly aligned, which blocks the airflow path of the ventilation system and affects the uniform distribution of air volume and ventilation efficiency.

[0005] In addition, the air volume blown out by the ventilation bag through the ventilation holes will be partially absorbed by the foam, resulting in air volume loss, thereby weakening the ventilation performance. This air volume attenuation problem seriously affects the actual effect of the seat ventilation system and cannot meet the user's demand for a good ventilation experience. Summary of the invention

[0006] In view of the above-mentioned defects or deficiencies in the prior art, the present application aims to provide a porous distributed closed installation structure of a car seat ventilation system and a car seat to improve the ventilation effect.

[0011] According to the technical solution provided in the embodiment of the present application, the connection structure includes a second connection member, which is a plurality of inclined protrusions arranged at intervals along the circumferential direction of the outer wall surface of the air guide portion.

[0012] According to the technical solution provided in the embodiment of the present application, the connecting structure includes a third connecting member, which is an annular flange formed by radially extending from the edge of one end of the air guide portion away from the mounting portion, and when the air guide portion is embedded in the corresponding ventilation hole, the third connecting member abuts against a side of the foam layer away from the ventilation bag side.

[0013] According to the technical solution provided in the embodiment of the present application, the connection structure includes a fourth connecting member, which is a plurality of protrusion structures with snap-in grooves and reinforcing ribs arranged circumferentially along the outer wall surface of the air guide portion. When the air guide portion is embedded in the corresponding ventilation hole, the snap-in member is snapped into the snap-in groove.

In addition, with such a porous distributed closed installation structure, the ventilation holes can be set at any position of the seat, which can expand the ventilation area and improve the actual effect of the ventilation system.

[0020] 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.

[0021] 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.

[0022] Example 1 As mentioned in the background technology, in order to solve the problems in the prior art, this application proposes a multi-porous distributed closed installation structure for a car seat ventilation system, please refer to Figure 1 , 2 As shown in Figure 3, the ventilation system at least includes a ventilation bag 1, wherein the ventilation bag 1 has a first cavity, a fan connected to the first cavity is provided on the side of the ventilation bag away from the foam layer, and a plurality of air distribution holes 4 connected to the first cavity are provided on the side of the ventilation bag 1 close to the foam layer 3, a plurality of ventilation holes 5 are penetrated at positions corresponding to the foam layer 3 and the air distribution holes 4, and a closed air guide component is respectively provided at each of the air distribution holes 4, and the closed air guide component includes an air guide portion 22 matching the ventilation holes 5, and an installation portion 23 is provided at one end of the air guide portion 22 close to the ventilation bag 1, and the installation portion 23 is used to install the closed guide The wind assembly is fixed on the ventilation bag 1; the outer wall surface of the air guide portion 22 away from the mounting portion 23 is provided with at least one layer of connection structure along the first direction and circumferentially, and the connection structure is used to embed the air guide portion 22 into the corresponding ventilation hole 5, so that the outer wall surface of the air guide portion 22 is tightly connected with the inner wall surface of the corresponding ventilation hole 5, so as to install the ventilation bag 1 on the foam layer 3; specifically, compared with the traditional structure (because air leakage will not set the ventilation hole in the corner position of the foam), with such a porous distributed closed mounting structure, the ventilation hole can be set at any position of the seat, so as to achieve the actual effect of expanding the ventilation area. The air guide portion 22 has a hollow cavity connected to the first cavity inside, and the end of the air guide portion 22 away from the mounting portion 23 is provided with a first air outlet connected to the hollow cavity.

[0023] Specifically, when the air guide 22 is embedded in the corresponding ventilation hole 5, the air distribution hole 4, the ventilation hole 5 and the first air outlet are coaxially arranged. The air guide 22 and the connection structure are arranged so that the air distribution hole 4, the ventilation hole 5 and the first air outlet can be accurately coaxially arranged during the installation process. This effectively solves the problem that the ventilation hole 5 cannot be completely aligned due to tolerance reasons, ensures that the air flow channel is unobstructed, improves ventilation efficiency, and enables the air volume to be evenly distributed, providing users with a more comfortable ventilation experience.

[0024] Specifically, the mounting portion 23 is in the shape of a disc and is mounted on the ventilation bag 1 by welding, ensuring that the mounting portion 23 is firmly connected to the ventilation bag 1 and will not fall off easily. During installation, align the mounting portion 23 with a suitable position on the ventilation bag 1 (the ventilation bag 1 close to the air distribution hole 4 on the side of the foam layer 3 or the projection of the ventilation bag 1 away from the foam layer 3) and apply a certain pressure to firmly fix it on the ventilation bag 1.

[0025] An air guide portion 22, the air guide portion 22 being disposed on one side of the mounting portion 23, the air guide portion 22 having a hollow cavity in communication with the first cavity, and the air guide portion 22 having a first air outlet in communication with the hollow cavity on a side away from the mounting portion 23; Specifically, the air guide portion 22 can be made of hard plastic or other materials with certain strength and wear resistance. The hollow cavity inside it should be designed as a smooth channel to reduce air flow resistance.

[0026] The length of the air guide 22 can be adjusted according to actual needs to ensure that the ventilation bag 1 and the foam layer 3 can be effectively connected, and the air distribution hole 4, the ventilation hole 5 and the first air outlet can be accurately coaxially arranged. In the manufacturing process, injection molding and other processes can be used to ensure the dimensional accuracy and quality stability of the air guide 22.

[0027] Specifically, the connection structure should be easy to operate and be able to provide sufficient connection strength to ensure that it will not loosen or fall off during the driving of the vehicle.

[0028] Specifically, in this embodiment, the air guide portion 22 of the extended tubular structure can be installed and sealed with the foam layer 3 and the non-woven fabric on the foam layer 3B, thereby reducing the double-sided tape layer of the ventilation bag 1 and avoiding air leakage, abnormal noise, and odor problems caused by loose adhesion of the double-sided tape.

[0029] When actually installing the ventilation system, first install the mounting portion 23 on the ventilation bag 1, then seal the outer wall surface of the air guide portion 22 with the inner wall surface of the corresponding ventilation hole 5, and install the ventilation bag 1 on the foam layer 3. During the connection process, ensure that the air distribution hole 4, the ventilation hole 5 and the first air outlet are completely coaxial to ensure that the air flow channel of the ventilation system is unobstructed. Specialized installation tools or auxiliary devices can be used to help achieve accurate installation and alignment. At the same time, after the installation is completed, inspection and testing should be carried out to ensure that the performance of the ventilation system meets the design requirements.

[0030] Furthermore, when the air guiding portion 22 is embedded in the corresponding ventilation hole 5 , the air guiding portion 22 is interference-connected with the foam layer 3 through the connecting structure 2 .

[0031] Specifically, in this embodiment, the connection structure provided on the air guiding portion 22 is directly connected to the foam layer 3 .

[0032] Furthermore, a snap-fit ​​structure corresponding to the closed air guide component is provided on the foam layer 3, and the snap-fit ​​structure includes at least one snap-fit ​​part 6 for snapping with the connecting structure 2; when the air guide part 22 is embedded in the corresponding ventilation hole 5, the connecting structure 2 is interference connected with the foam layer 3, and at least one layer of the connecting structure 2 is snap-fitted with the snap-fit ​​part 6.

[0033] Specifically, multiple layers of the snap-fitting parts may be provided. The snap-fitting parts may be snap rings pre-buried in the foam layer 3 or may be attachments attached to the B surface of the foam layer 3. Exemplarily, the attachments are perforated non-woven fabrics.

[0034] Specifically, the clamping structure 2 is installed to the edge of the ventilation bag 1 to lock the foam and seal it, thereby reducing the distance limit of the edge of the air bag and increasing the control area of ​​the ventilation system.

[0035] For further information, please refer to Figure 1 , Figure 4 , Figure 8 , Fig.11 , Fig.12 , Fig.19 As shown, the mounting portion 23 is installed on a side of the ventilation bag 1 close to the foam layer 3, the mounting portion 23 is arranged in the air distribution hole 4, and a second air outlet for connecting the first cavity and the hollow cavity is provided on the mounting portion 23.

[0036] Specifically, when the mounting portion 23 is installed on the surface of the ventilation bag 1 close to the foam layer 3, a through hole must be opened on the mounting portion 23 so that the airflow in the ventilation bag 1 can flow into the hollow cavity of the air guide portion 22 and then be blown out through the ventilation hole 5 to complete the ventilation work.

[0037] For further information, please refer to Figure 7 , Fig.14 , Fig.17 , Fig. 22 As shown, the mounting portion 23 is mounted on the side of the ventilation bag 1 away from the foam layer 3, and the air guide portion 22 has at least one first air inlet groove 25. When the mounting portion 23 is mounted on the surface of the ventilation bag 1 away from the foam layer 3, the air guide portion 22 passes through the air distribution hole 4 and the hollow cavity is connected to the first cavity through the first air inlet groove 25.

[0038] Specifically, the connection structure 2 on the side of the ventilation bag 1 away from the foam layer 3 and the connection structure 2 on the side of the ventilation bag 1 close to the foam layer 3 can be mixed. For details, please refer to Figure 1 As shown, it is located at the corresponding position of the fan 8 ( Figure 1 The four located in the middle at the top) use the connection structure 2 on the side of the ventilation bag 1 away from the foam layer 3, and the other positions except the corresponding positions of the fan 8 use the connection structure 2 on the side of the ventilation bag 1 close to the foam layer 3.

[0039] Specifically, when the mounting portion 23 is mounted on the surface of the ventilation bag 1 away from the foam layer 3, it is mounted on the inner side of the surface of the ventilation bag 1 away from the foam layer 3, and at the projection position of the air distribution hole 4. When it is mounted on the surface of the ventilation bag 1 away from the foam layer 3, the mounting portion 23 does not need to have a hole. However, since the air guide portion 22 needs to pass through the first cavity, it is necessary to have a first air inlet groove 25 on the air guide portion 22 so that the air flow in the first cavity can enter the hollow cavity and then be blown out from the first air outlet through the hollow cavity. In addition, the suction type fan 8 can also be used. Under the action of suction, the air inside the seat enters the air guide portion 22 through the ventilation hole 5 of the foam layer 3, and the air flows from the air guide portion 22 into the first cavity, and then can be sucked out by the suction type fan 8.

[0040] In a preferred embodiment, please refer to Figure 18-Figure 22 As shown, the connecting structure 2 includes a third connecting member 29, which is an annular flange radially extending from the edge of one end of the air guide portion 22 away from the mounting portion 23. When the air guide portion 22 is embedded in the corresponding ventilation hole 5, the third connecting member 29 abuts against a side of the foam layer 3 away from the ventilation bag 1.

[0041] In a preferred embodiment, please refer to Figure 3 , Figure 4 As shown, the connection structure 2 includes a second connection member, which is a plurality of inclined surface protrusions 21 arranged at intervals along the circumferential direction of the outer wall surface of the air guide portion.

[0042] The inclined surface protrusion 21 has a clamping groove, and the clamping member 6 can be clamped in the clamping groove of the inclined surface protrusion 21 close to the mounting portion 23 or in the clamping groove of the inclined surface protrusion 21 far from the mounting portion 23 .

[0043] Specifically, the two inclined protrusions 21 can be used separately as complementary devices. In case of assembly failure of the primary buckle (the inclined protrusion 21 close to the foam layer 3), it will automatically switch to the secondary buckle (the inclined protrusion 21 away from the foam layer 3) to ensure the stability of the buckle. Moreover, when the buckle automatically disengages, the buckle can be automatically reset after the occupant takes the seat for the second time.

[0044] In a preferred embodiment, please refer to Figure 8-Figure 10 as well as Fig.24 As shown, the connection structure 2 includes a first connection member, which is an annular ramp 26 arranged along the circumference of the outer wall of the air guide portion.

[0045] Specifically, when the air guide portion 2 is embedded in the corresponding ventilation hole 5 , the connection structure 2 is interference-connected with the foam layer 3 , and the annular ramp 26 is engaged with the engaging member 6 .

[0046] Specifically, the sharp corners of the annular ramp 26 need to be chamfered to prevent the sharp corners from scratching the foam (except at the mold parting line).

[0047] Specifically, the annular ramp 26 can be a layer, that is, a layer of snap-fit ​​structure is formed ( Figure 8 ,in Figure 8 a is before assembly, Figure 8 b is after assembly), it can also be two layers, that is, a two-layer buckle structure is formed ( Fig. 9 ,in Fig. 9 a is before assembly, Fig. 9 b is after assembly), it can also be three layers, that is, a three-layer buckle structure is formed (such as Fig.11 The three-layer buckle structure shown, Fig.10 is the assembly drawing, where Fig.10 a is before assembly, Fig.10 b is after assembly), further, a cross structure is provided inside the annular ramp 26 ( Fig.12 ), in which a cross structure is used to reinforce its strength.

[0048] Furthermore, the connecting structure 2 includes a fourth connecting member, which is a plurality of protrusion structures 27 with snap-in grooves 271 and reinforcing ribs 28 arranged circumferentially along the outer wall surface of the air guide portion. When the air guide portion 22 is embedded in the corresponding ventilation hole 5, the snap-in member 6 is snapped into the snap-in groove 271.

[0049] Specifically, please refer to Figure 15-17 as well as Fig.23As shown, four convex block structures 27 are provided, and reinforcing ribs 28 are provided on the convex block structures 27. The clamping groove 271 is clamped with the B surface attachment of the foam layer 3, and the clamping groove 271 can be used alone. In this embodiment, the inclined surface convex block 21 can also be provided, and the inclined surface convex block 21 is clamped with the inner wall of the ventilation hole 5 of the foam layer 3 by interference fit, and the inclined surface convex block 21 can be used alone. The clamping groove 271 and the inclined surface convex block 21 are complementary devices, and are clamped and fixed at the same time to ensure the clamping stability. If the clamping device fails or the buckle is accidentally disengaged, the buckle can be automatically reset after the occupant rides for the second time.

[0050] In a preferred embodiment, an extension structure is provided on the side of the mounting portion 23 away from the air guiding portion 22 , and the extension structure is used for mounting other components of the ventilation system.

[0051] Optionally, refer to Figure 5 , Figure 6 , Fig.13 , Fig.21 and Fig. 22 As shown, the extension structure is a rubber rivet 7 , and the rubber rivet 7 is installed in the hole position of the mounting hole 24 reserved in the mounting portion 23 , and then the fan 8 is fixed on the rubber rivet 7 .

[0052] Optionally, the extension structure may also be a spring frame clamp 9, which is fixed to the spring frame.

[0053] Optionally, the extension structure may also be a wiring harness buckle 10 for fixing an external wiring harness of the fan 8 .

[0054] Example 2 On the basis of Example 1, this example proposes a car seat, comprising a ventilation bag 1 and a foam layer 3, wherein the ventilation bag 1 is installed on the foam layer 3 through the porous distributed closed installation structure of the car seat ventilation system described above.

[0055] Specifically, the vehicle seats equipped with the distributed air vents and closed mounting structure of the automobile seat ventilation system can enhance the riding experience. The stable and efficient ventilation system can provide passengers with a continuous cool feeling, especially in hot weather or when driving for a long time, effectively improving the comfort of the seats. It reduces the discomfort caused by stuffiness and makes passengers more relaxed and happy during the ride. In addition, the good ventilation effect helps to reduce the accumulation of moisture and heat inside the seats, and reduces the risk of aging and damage of seat materials due to moisture and high temperature. At the same time, the reliable mounting structure also reduces the potential damage to the seats caused by ventilation system failures, extending the overall service life of the automobile seats.
