Description

TECHNICAL AREA

[0001] The present application relates to the technical field of vehicle ventilation, in particular a porous-distributed dense mounting structure for a ventilation system of a vehicle seat and a vehicle seat. STATE OF THE ART

[0002] With the ever-increasing demands on driving comfort, ventilation systems for seats are finding widespread use in various seat types. However, there are currently several technical problems associated with installing ventilation systems on seats.

[0003] On the one hand, the method of fixing the ventilation bags is too monotonous and relies too heavily on mounting with double-sided adhesive tapes. This mounting method often leads to insufficient adhesion, especially in extreme positions where an effective seal cannot be achieved. This not only affects the stability of the ventilation system but can also lead to problems such as air leakage, which impairs the ventilation effect.

[0004] On the other hand, due to tolerances during the assembly of the ventilation holes with the foam, incomplete alignment of the ventilation holes often occurs. This obstructs the airflow channels of the ventilation system, impairing an even distribution of airflow and reducing ventilation efficiency.

[0005] Furthermore, some of the air blown out of the ventilation bag through the ventilation holes is absorbed by the foam, resulting in a loss of airflow and consequently reduced ventilation performance. This problem of reduced airflow significantly impairs the actual effectiveness of the seat ventilation system and prevents it from meeting user requirements for a comfortable ventilation experience. ILLUSTRATION OF THE USE SAMPLE

[0006] In view of the aforementioned defects or deficiencies in the prior art, the present application is intended to provide a porous-distributed dense assembly structure for a ventilation system of a vehicle seat, as well as a vehicle seat, to improve the ventilation effect.

[0007] In a first aspect, the present application proposes a porous-distributed dense assembly for a ventilation system of a vehicle seat, wherein the ventilation system comprises at least one ventilation bag in which a first cavity is provided, wherein a fan is provided on a side of the ventilation bag furthest from a foam layer, communicating with the first cavity, and wherein several air distribution holes are provided on a side of the ventilation bag near the foam layer, communicating with the first cavity, and wherein several ventilation holes are arranged continuously in the foam layer at the positions corresponding to the air distribution holes, wherein a dense air guide component is arranged at each air distribution hole, comprising an air guide section adapted to the ventilation hole.wherein at one end of the air duct section near the ventilation bag a mounting section is arranged for fixing the tight air duct component to the ventilation bag; wherein at least one layer of connecting structure is arranged circumferentially in a first direction on the outer wall surface at an end of the air guide section remote from the mounting section, which is designed to embed the air guide section in the corresponding ventilation hole, such that the outer wall surface of the air guide section is tightly connected to the inner wall surface of the corresponding ventilation hole in order to mount the ventilation bag to the foam layer; and wherein the air guidance section has an internal cavity that communicates with the first cavity, and a first air outlet is arranged at an end of the air guidance section remote from the assembly section, which communicates with the cavity.

[0008] According to a technical solution provided by an embodiment of the present application, the air guide section is connected to the foam layer via a press fit through the connecting structure when the air guide section is embedded in the corresponding ventilation hole.

[0009] According to a technical solution provided by an embodiment of the present application, a snap-fit ​​connection structure corresponding to the dense air guide component is arranged on the foam layer, comprising at least one locking element for snapping into the connection structure; wherein the connection structure is connected to the foam layer via a press fit and at least one layer of the connection structure is snap-fit ​​connected to the locking element when the air guide section is embedded in the corresponding ventilation hole.

[0010] According to a technical solution provided by an embodiment of the present application, the connecting structure comprises a first connecting element which is an annular slope arranged circumferentially around the outer wall surface of the air duct section.

[0011] According to a technical solution provided by an embodiment of the present application, the connecting structure comprises second connecting elements, which are several inclined studs arranged spaced apart from one another around the outer wall surface of the air duct section.

[0012] According to a technical solution provided by an embodiment of the present application, the connecting structure comprises a third connecting element, which is an annular collar formed by a radial extension of the flank of the air guide section at one end away from the mounting section, wherein the third connecting element bears against a surface of the side of the foam layer furthest from the ventilation bag when the air guide section is embedded in the corresponding ventilation hole.

[0013] According to a technical solution provided by an embodiment of the present application, the connecting structure comprises fourth connecting elements, which are several stud structure bodies arranged circumferentially spaced apart from one another around the outer wall surface of the air guide section, with a snap groove and a stiffening rib, wherein the locking element is engaged in the snap groove when the air guide section is embedded in the corresponding ventilation hole.

[0014] According to a technical solution provided by an embodiment of the present application, the mounting section is mounted on the side of the ventilation bag furthest from the foam layer, and the air guide section has at least one first air inlet recess, wherein the air guide section penetrates the air distribution hole and the cavity communicates with the first cavity via the first air inlet recess when the mounting section is mounted on a surface of the side of the ventilation bag furthest from the foam layer.

[0015] According to a technical solution provided by an embodiment of the present application, the mounting section is mounted on the side of the ventilation bag near the foam layer, wherein the mounting section is arranged within the air distribution hole and a second air outlet for communication between the first cavity and the cavity is arranged on the mounting section.

[0016] In a second aspect, the present application proposes a vehicle seat comprising a ventilation bag and a foam layer, wherein the ventilation bag is mounted to the foam layer by the above-described porous-distributed dense mounting construction for a vehicle seat ventilation system.

[0017] In comparison to the prior art, the advantageous effects of the present application are that by arranging a tight air guide component when mounting the ventilation bag on the foam layer, a tight connection can be achieved between the outer wall surface of the air guide section and the inner wall surface of the corresponding ventilation hole, thereby providing a reliable fixing method for the ventilation bag, avoiding poor sealing problems caused by insufficient adhesion of adhesive tapes, and ensuring that the ventilation bag can be firmly mounted on the vehicle seat in various operating environments, especially in extreme positions, thus guaranteeing the stability of the ventilation system.At the same time, the precise alignment of the ventilation holes and the reliable fixing method reduce airflow loss caused by improper installation. This allows the cavity in the air guide section to better direct the airflow and reduces air absorption by the foam, effectively minimizing the reduction in ventilation performance and ensuring that the air blown from the ventilation bag can more efficiently act on the seat surface through the ventilation holes. Furthermore, this porous, distributed, and dense mounting design allows the ventilation holes to be positioned anywhere on the seat, thus increasing the ventilated area and improving the overall effectiveness of the ventilation system.

[0019] The present application is explained in more detail below in conjunction with the accompanying drawings and embodiments. It is understood that the specific embodiments described herein serve only to interpret the invention and do not constitute a limitation of this invention. It should also be noted that, for the sake of clarity, only the parts dependent on the invention are shown in the accompanying drawings.

[0020] It should be noted that the embodiments and features in the embodiments in the present application may be combined with one another as long as there is no conflict. The present application is explained in detail below with reference to the accompanying drawings and in conjunction with the embodiments. Example 1

[0021] As mentioned in the prior art, the present application proposes, as a solution to the problems of the existing technology, a porous-distributed dense mounting structure for a ventilation system of a vehicle seat, as described with reference to Fig. 1, Fig. 2, Fig. 3 is shown, wherein the ventilation system comprises at least one ventilation bag 1 in which a first cavity is provided, wherein a fan is provided on a side of the ventilation bag away from a foam layer which communicates with the first cavity, and wherein several air distribution holes 4 are provided on a side of the ventilation bag 1 near the foam layer 3 which communicate with the first cavity, and wherein several ventilation holes 5 are arranged continuously at the positions in the foam layer 3 corresponding to the air distribution holes 4, wherein a tight air guide component is arranged at each of the air distribution holes 4, comprising an air guide section 22 which is adapted to the ventilation hole 5, and wherein a mounting section 23 for fixing the tight air guide component to the ventilation bag 1 is arranged at one end of the air guide section 22 near the ventilation bag 1; wherein at least one layer of connecting structure is arranged circumferentially in a first direction on the outer wall surface at an end of the air guide section 22 remote from the mounting section 23, which is designed to embed the air guide section 22 in the corresponding ventilation hole 5, such that the outer wall surface of the air guide section 22 is tightly connected to the inner wall surface of the corresponding ventilation hole 5 in order to mount the ventilation bag 1 to the foam layer 3. In particular, such a porous-distributed, dense mounting structure, compared to traditional designs (where ventilation holes are not placed in the corners of the foam due to air leakage), allows ventilation holes to be arranged at any position on the seat, resulting in an actual increase in the ventilated area.

[0022] The air guidance section 22 has an internal cavity that communicates with the first cavity, and at an end of the air guidance section 22 remote from the assembly section 23, a first air outlet is arranged that communicates with the cavity.

[0023] In particular, the air distribution hole 4, the ventilation hole 5, and the first air outlet are arranged coaxially when the air guide section 22 is embedded in the corresponding ventilation hole 5. The arrangement of the air guide section 22 and the connecting structure enables precise coaxial alignment of the air distribution hole 4, the ventilation hole 5, and the first air outlet during the assembly process. This effectively solves the problem of incomplete alignment of the ventilation holes 5 due to tolerances, ensures an unobstructed airflow channel, improves ventilation efficiency, allows for a uniform distribution of the air volume, and thus provides the user with a more comfortable ventilation experience.

[0024] In particular, the mounting section 23 is disc-shaped and is mounted to the ventilation bag 1 by welding to ensure a firm and secure connection between the mounting section 23 and the ventilation bag 1. During assembly, the mounting section 23 is aligned to the appropriate position on the ventilation bag 1 (either at the air distribution hole 4 on the side of the ventilation bag 1 near the foam layer 3 or at the projection point of the air distribution hole 4 on the side of the ventilation bag 1 furthest from the foam layer 3) and subjected to pressure so that the mounting section is firmly fixed to the ventilation bag 1.

[0025] The air guidance section 22 is provided on one side of the assembly section 23, wherein the air guidance section 22 has a cavity inside which communicates with the first cavity, and on a side of the air guidance section 22 away from the assembly section 23 a first air outlet is arranged which communicates with the cavity.

[0026] In particular, the air guide section 22 can be made of hard plastic or other materials with a certain degree of strength and wear resistance. The cavity inside it should be designed as a smooth channel to reduce flow resistance.

[0027] The length of the air guide section 22 can be adjusted according to actual requirements to ensure an effective connection between the ventilation bag 1 and the foam layer 3 and to enable a precise coaxial arrangement of the air distribution hole 4, ventilation hole 5, and first air outlet. During the manufacturing process, processes such as injection molding can be used to ensure the dimensional accuracy and quality stability of the air guide section 22.

[0028] In particular, the connection structure should be easy to handle and provide sufficient connection strength to prevent loosening or detachment while a vehicle is in motion.

[0029] In this embodiment, in particular, the extending tubular air guide section 22 and the foam layer 3 or the fleece on the B-surface of the foam layer 3 enable assembly and sealing, thereby reducing the layer of double-sided adhesive tape on the ventilation bag 1. This prevents air leaks or noise caused by insufficient adhesion of the double-sided adhesive tape, as well as odor problems associated with the double-sided adhesive tape.

[0030] During the practical assembly of the ventilation system, the mounting section 23 is first attached to the ventilation bag 1. Then, the outer wall surface of the air guide section 22 is tightly connected to the inner wall surface of the corresponding ventilation opening 5, so that the ventilation bag 1 is mounted to the foam layer 3. During the connection process, it must be ensured that the air distribution opening 4, the ventilation opening 5, and the first air outlet are fully coaxial to guarantee an unobstructed airflow channel for the ventilation system. Special assembly tools or aids can be used to assist with precise assembly and alignment. After completion of the assembly, checks and tests should also be carried out to ensure that the performance of the ventilation system meets the design requirements.

[0031] Furthermore, the air guide section 22 is connected to the foam layer 3 via a press fit through the connecting structure 2 when the air guide section 22 is embedded in the corresponding ventilation hole 5.

[0032] In particular, this embodiment relates to a direct connection of the connecting structure mounted on the air guide section 22 with the foam layer 3.

[0033] Furthermore, a snap-fit ​​connection structure corresponding to the dense air guide component is arranged on the foam layer 3, which includes at least one locking element 6 for snapping into the connection structure 2, wherein the connection structure 2 is connected to the foam layer 3 via a press fit and at least one layer of the connection structure 2 is snap-fit ​​connected to the locking element 6 when the air guide section 22 is embedded in the corresponding ventilation hole 5.

[0034] In particular, several layers of the locking elements can be arranged, wherein the locking elements can be locking rings pre-drilled into the foam layer 3 or attachments, e.g. perforated fleece, placed on the B-surface of the foam layer 3.

[0035] In particular, the snap-fit ​​structure 2 is mounted on the edge of the ventilation bag 1 to fix and seal the foam, reduce the spacing restriction at the edge of the ventilation bag and increase the control area of ​​the ventilation system.

[0036] Furthermore, with reference to the Fig. 1, Fig. 4, Fig. 8, Fig. 11, Fig. 12 and Fig. 19 the mounting section 23 is mounted on the side of the ventilation bag 1 near the foam layer 3, wherein the mounting section 23 is arranged inside the air distribution hole 4 and a second air outlet is arranged on the mounting section 23 for communication between the first cavity and the cavity.

[0037] In particular, a through-hole must be provided in the assembly section 23 so that the airflow within the ventilation bag 1 can flow into the cavity of the air guide section 22 and is then blown out through the ventilation hole 5, so that the ventilation work is completed when the assembly section 23 is mounted on the surface of the side of the ventilation bag 1 near the foam layer 3.

[0038] Furthermore, with reference to the Fig. 7, Fig. 14, Fig. 17 and Fig. 22 the mounting section 23 is mounted on the side of the ventilation bag 1 furthest from the foam layer 3 and the air guide section 22 has at least one first air inlet recess 25, wherein the air guide section 22 penetrates the air distribution hole 4 and the cavity communicates with the first cavity via the first air inlet recess 25 when the mounting section 23 is mounted on a surface of the side of the ventilation bag 1 furthest from the foam layer 3.

[0039] In particular, the connection structure 2 on the side of the ventilation bag 1 furthest from the foam layer 3 and the connection structure 2 on the side of the ventilation bag 1 near the foam layer 3 can be used in combination. In particular, with reference to Fig. 1 at the positions corresponding to fan 8 (the four upper middle ones in Fig. 1) The connecting structure 2 is used on the side of the ventilation bag 1 furthest from the foam layer 3. In all other positions except those corresponding to the fan 8, the connecting structure 2 is used on the side of the ventilation bag 1 closest to the foam layer 3.

[0040] In particular, the mounting section 23 is mounted on the inside surface of the side of the ventilation bag 1 furthest from the foam layer 3, specifically at the projection position of the air distribution hole 4, when the mounting section is mounted on the surface of the side of the ventilation bag 1 furthest from the foam layer 3. If the mounting section is mounted on the surface of the side of the ventilation bag 1 furthest from the foam layer 3, it is not necessary to provide holes in the mounting section 23. However, since the air guide section 22 is to penetrate the first cavity, a first air inlet recess 25 must be provided in the air guide section 22 so that the airflow can enter the cavity within the first cavity and then be expelled through the cavity via the first air outlet. An intake fan 8 can also be used.Under suction, the air inside the seat enters the air guide section 22 through the ventilation holes 5 of the foam layer 3, whereby the air flows from the air guide section 22 into the first cavity and can then be extracted by the intake fan 8.

[0041] In a preferred embodiment, with reference to the Fig. 18-22 the connecting structure 2 a third connecting element 29, which is a ring collar formed by a radial extension of the flank of the air guide section 22 at one end away from the assembly section 23, wherein the third connecting element 29 rests against a surface of the side of the foam layer 3 away from the ventilation bag 1 when the air guide section 22 is embedded in the corresponding ventilation hole 5.

[0042] In a preferred embodiment, with reference to the Fig. 3 and Fig. 4 the connecting structure 2 second connecting elements, which are several inclined studs 21, which are arranged circumferentially spaced apart from each other around the outer wall surface of the air guide section.

[0043] The angled stud 21 has a snap groove. The locking element 6 can snap into the snap groove of the angled stud 21 near the mounting section 23 or into the snap groove of the angled stud 21 furthest from the mounting section 23.

[0044] In particular, the two angled studs 21 can be used individually and are complementary devices. If the primary locking mechanism (the angled stud 21 on the side near the foam layer 3) fails, it automatically switches to the secondary locking mechanism (the angled stud 21 on the side furthest from the foam layer 3), thus ensuring snap-in stability. If the locking mechanism is accidentally released, it can be automatically reset by the occupant sitting down again.

[0045] In a preferred embodiment, with reference to the Fig. 8-10 and 24 the connecting structure 2 a first connecting element which is an annular slope 26 which is arranged circumferentially around the outer wall surface of the air duct section.

[0046] In particular, the connecting structure 2 is connected to the foam layer 3 via a press fit and the annular chamfer 26 is snap-fitted to the locking element 6 when the air guide section 22 is embedded in the corresponding ventilation hole 5.

[0047] In particular, the sharp corners of the ring-shaped slope 26 must be rounded to prevent damage to the foam from the sharp corners (except at the point on the parting line of the mold).

[0048] In particular, the ring-shaped slope 26 can be single-layered, i.e., form a single-layer grid structure ( Fig. 8, wherein Fig. 8a the condition before assembly and Fig. 8b shows the state after assembly), or be two-layered, i.e., form a two-layer grid structure ( Fig. 9, wherein Fig. 9a the condition before assembly and Fig. 9b shows the state after assembly), or be three-layered, i.e., form a three-layer grid structure (like the one in Fig. 11 three-layer grid structure shown, wherein Fig. 10 is an assembly view, where Fig. 10a the condition before assembly and Fig. 10b shows the state after assembly). Furthermore, within the ring-shaped slope 26 there is a crossing structure ( Fig. 12) provided, the intersecting structure serving to reinforce its strength.

[0049] Furthermore, the connecting structure comprises two fourth connecting elements, which are several studded structure bodies 27 arranged circumferentially apart from one another around the outer wall surface of the air guide section, with a snap groove 271 and a stiffening rib 28, wherein the locking element 6 is engaged in the snap groove 271 when the air guide section 22 is embedded in the corresponding ventilation hole 5.

[0050] In particular, with reference to the Fig. Four studded structure bodies 27 are arranged at points 15-17 and 23, each with a stiffening rib 28. The snap groove 271 is snap-fitted to the attachments on the B-surface of the foam layer 3. The snap groove 271 can be used independently. In this embodiment, the angled studs 21 can also be arranged, which are snap-fitted to the inner wall of the ventilation hole 5 of the foam layer 3 via an interference fit. The angled studs 21 can also be used independently. The snap groove 271 and the angled studs 21 are complementary devices that are simultaneously and firmly snap-fitted to each other, ensuring snap stability. If the snap mechanism fails or the detent is unintentionally released, the detent can be automatically reset by the occupant sitting down again.

[0051] In a preferred embodiment, an extension structure for mounting other elements of the ventilation system is provided on the side of the mounting section 23 furthest from the air guide section 22.

[0052] Alternatively, with reference to the Fig. 5, Fig. 6, Fig. 13, Fig. 21 and Fig. 22 the extension structure a rubber blind rivet which is mounted on a mounting hole 24 specified for the assembly section 23 and then the fan 8 is fixed to the rubber blind rivet 7.

[0053] Alternatively, the extension structure can also be a spring carrier clamp 9 to which a spring carrier is fixed.

[0054] Alternatively, the extension structure can also be a cable holder 10 for fixing the external cables of the fan 8. Example 2

[0055] Based on embodiment 1, this embodiment proposes a vehicle seat comprising a ventilation bag 1 and a foam layer 3, wherein the ventilation bag 1 is mounted on the foam layer 3 by the above-described porous-distributed dense mounting construction for a vehicle seat ventilation system.

[0056] In particular, a vehicle seat equipped with this tightly mounted design for a ventilation system with distributed air vents can enhance the seating experience. A stable and efficient ventilation system can provide occupants with a sustained feeling of coolness and effectively increase seat comfort, especially in hot weather or on long journeys. This reduces the discomfort caused by stifling heat, allowing occupants to be more relaxed and satisfied during the journey. Furthermore, good ventilation helps reduce moisture and heat buildup inside the seat, thus minimizing the risk of aging and damage to the seat material caused by moisture and high temperatures. At the same time, the reliable mounting design also reduces potential damage to the seat due to ventilation system malfunctions, extending the overall lifespan of the vehicle seat.
