Description

[Technical Field]

[0001] The present application relates to the technical field of vehicle ventilation, and in particular to a porous distributed sealing mounting structure for a vehicle seat ventilation system and a vehicle seat. [Background technology]

[0002] As people's demands for riding comfort continue to increase, seat ventilation systems have been widely applied to various seats, but conventional seats have various technical problems in the arrangement of ventilation systems.

[0003] The air bag is fixed in a single way, relying too heavily on double-sided tape, which often results in insufficient adhesion and an ineffective seal, especially at extreme locations, which not only affects the stability of the ventilation system but also leads to problems such as air leakage and reduces the ventilation effect.

[0004] Meanwhile, during the assembly process between the ventilation holes and the foam, due to tolerances, the ventilation holes often cannot be perfectly aligned, which further causes the airflow path of the ventilation system to become uneven, affecting the uniform distribution of airflow and ventilation efficiency.

[0005] In addition, a portion of the airflow blown out from the ventilation bag through the ventilation holes is absorbed by the foam, resulting in airflow loss and reduced ventilation performance. This problem of reduced airflow severely affects the effectiveness of the seat ventilation system and fails to meet users' needs for a good ventilation experience.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The present application will be described in more detail below with reference to the drawings and examples. The specific examples described herein do not limit the present invention, but are merely used to interpret the related invention. For ease of description, only parts relevant to the invention are shown in the drawings.

[0020] Hereinafter, the present application will be described in detail with reference to the accompanying drawings, in which: FIG.

[0021] Example 1 As mentioned in the Background Art, in order to solve the problems of the prior art, the present application provides a multi-hole distributed sealed mounting structure for an automobile seat ventilation system, and as shown in Figures 1, 2 and 3, the ventilation system includes at least a ventilation bag 1, a first cavity is provided inside the ventilation bag 1, a fan is provided on the side of the ventilation bag away from the foam layer and communicates with the first cavity, several air distribution holes 4 are provided on the side of the ventilation bag close to the foam layer 3 and communicate with the first cavity, several ventilation holes 5 are arranged in the foam layer 3 at positions corresponding to the air distribution holes 4 so as to pass through, each of the air distribution holes 4 is provided with a sealed air guide unit, the sealed air guide unit includes an air guide section 22 corresponding to the ventilation hole 5, and one end of the air guide section 22 close to the ventilation bag 1 is provided with an attachment section 23 for fixing the sealed air guide unit to the ventilation bag 1, At least one layer of connecting structure is provided circumferentially along the first direction on the outer wall surface of one end of the air guide section 22 remote from the mounting section 23, and the connecting structure fits the air guide section 22 into the corresponding ventilation hole 5, sealingly connecting the outer wall surface of the air guide section 22 and the inner wall surface of the corresponding ventilation hole 5, thereby attaching the ventilation bag 1 to the foam layer 3. Specifically, compared to the traditional structure (where ventilation holes are not located at foamed corners due to air leakage), this type of porous distributed sealed mounting structure allows ventilation holes to be located at any position on the seat, thereby achieving the effect of expanding the ventilation area.

[0022] A hollow cavity communicating with the first cavity is provided inside the airflow guidance section 22, and a first exhaust port communicating with the hollow cavity is provided at one end of the airflow guidance section 22 away from the mounting section 23.

[0023] Specifically, when the air guide section 22 is fitted into the corresponding ventilation hole 5, the air distribution hole 4, the ventilation hole 5, and the first exhaust port are coaxially arranged. By arranging the air guide section 22 and the connecting structure, the air distribution hole 4, the ventilation hole 5, and the first exhaust port can be precisely and coaxially arranged during the installation process. This effectively solves the situation where the ventilation holes 5 cannot be perfectly aligned due to tolerances, ensures smooth passage of the airflow path, improves ventilation efficiency, and distributes the air volume evenly, providing users with a better ventilation experience.

[0024] Specifically, the mounting part 23 is disk-shaped and is attached to the ventilation bag 1 by welding, ensuring a strong connection between the mounting part 23 and the ventilation bag 1 and making it difficult to come off. When attaching, the mounting part 23 is aligned with an appropriate position on the ventilation bag 1 (the four air distribution holes on the side of the ventilation bag 1 close to the foam layer 3, or the projection of the air distribution holes 4 on the side of the ventilation bag 1 away from the foam layer 3), and a certain pressure is applied to firmly fix it to the ventilation bag 1.

[0025] The air guide section 22 is provided on one side of the mounting section 23, and a hollow cavity communicating with the first cavity is provided inside the air guide section 22, and a first exhaust port communicating with the hollow cavity is provided on the side of the air guide section 22 away from the mounting section 23.

[0026] Specifically, the airflow guide 22 is made of hard plastic or other materials with certain strength and wear resistance, and the hollow cavity therein should be designed as a smooth passage to reduce airflow resistance.

[0027] The length of the air guide section 22 can be adjusted according to actual needs to effectively connect the ventilation bag 1 and the foam layer 3, and ensure that the air distribution holes 4, ventilation holes 5 and first exhaust port are precisely and coaxially arranged. During the manufacturing process, the size precision and quality stability of the air guide section 22 are ensured through processes such as injection molding.

[0028] Specifically, the connection structure should be easy to operate and provide sufficient connection strength to ensure that it will not come off or loosen during vehicle travel.

[0029] Specifically, in this embodiment, the air guide section 22, which has an extending tubular structure, is attached and sealed to the foam layer 3 and the nonwoven fabric on side B of the foam layer 3, thereby reducing the number of double-sided tape layers in the ventilation bag 1 and avoiding the problems of air leakage, abnormal noise, and the smell of double-sided tape caused by insufficient adhesion of the double-sided tape.

[0030] When actually installing the ventilation system, first, the mounting part 23 is attached to the ventilation bag 1, the outer wall surface of the air guide part 22 is sealed to the inner wall surface of the corresponding ventilation hole 5, and the ventilation bag 1 is then attached to the foam layer 3. During the connection process, the air distribution hole 4, the ventilation hole 5, and the first exhaust port must be perfectly coaxially aligned to ensure the airflow path of the ventilation system. Specialized installation tools or auxiliary devices are used to ensure accurate installation and alignment. After installation is complete, the ventilation system should be inspected and tested to ensure its performance meets the design requirements.

[0031] Furthermore, when the air guide section 22 is fitted into the corresponding ventilation hole 5, it is connected to the foam layer 3 by the connecting structure 2 with a tight fit.

[0032] Specifically, in this embodiment, the connection structure provided in the airflow guidance section 22 is directly connected to the foam layer 3 .

[0033] Furthermore, the foam layer 3 is provided with a locking structure corresponding to the sealed air guide unit, and the locking structure includes at least one engaging member 6 for locking to the connecting structure 2, and when the air guide section 22 is fitted into the corresponding ventilation hole 5, the connecting structure 2 is connected to the foam layer 3 with a tight fit, and at least one layer of the connecting structure 2 is locked to the engaging member 6.

[0034] Specifically, the engaging member may be arranged in multiple layers, and the engaging member may be a snap ring embedded inside the foam layer 3, or an attachment attached to side B of the foam layer 3, and for example, the attachment is an open nonwoven fabric.

[0035] Specifically, the locking structure 2 is attached to the edge of the ventilation bag 1 to lock and seal the foam, reducing the distance restriction of the air bag edge and expanding the control area of ​​the ventilation system.

[0036] Furthermore, as shown in Figures 1, 4, 8, 11, 12 and 19, the mounting portion 23 is attached to the side of the ventilation bag 1 close to the foam layer 3 and is provided within the air distribution hole 4, and the mounting portion 23 is provided with a second exhaust port for connecting the first cavity and the hollow cavity.

[0037] Specifically, when the mounting portion 23 is attached to the surface of the ventilation bag 1 that is close to the foam layer 3, only if a through hole is opened in the mounting portion 23, the air flow inside the ventilation bag 1 flows into the hollow cavity of the air guidance portion 22 and is then blown out through the ventilation hole 5, thereby completing the ventilation operation.

[0038] Furthermore, as shown in Figures 7, 14, 17 and 22, the mounting part 23 is attached to the side of the ventilation bag 1 away from the foam layer 3, and the air guide part 22 is provided with at least one first air intake groove 25, and when the mounting part 23 is attached to the surface of the ventilation bag 1 away from the foam layer 3, the air guide part 22 passes through the air distribution hole 4, and the hollow cavity is connected to the first cavity by the first air intake groove 25.

[0039] 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 used together. Specifically, as shown in Figure 1, the connection structure 2 on the side of the ventilation bag 1 away from the foam layer 3 is used for the corresponding positions of the fans 8 (the four in the upper middle in Figure 1), and the connection structure 2 on the side of the ventilation bag 1 close to the foam layer 3 is used for other positions except for the corresponding positions of the fans 8.

[0040] Specifically, when the mounting part 23 is attached to the surface of the ventilation bag 1 away from the foam layer 3, it is attached to the inside of the surface of the ventilation bag 1 away from the foam layer 3 and is located at the projection position of the air distribution hole 4. When the mounting part 23 is attached to the surface of the ventilation bag 1 away from the foam layer 3, there is no need to drill a hole in the mounting part 23. However, since the air guide part 22 passes through the first cavity, by opening a first air intake groove 25 in the air guide part 22, the air flow in the first cavity enters the hollow cavity and is then blown out from the first exhaust port through the hollow cavity. In addition, by using the air intake type fan 8, the air inside the seat enters the air guide part 22 through the ventilation holes 5 in the foam layer 3 by the air intake action, flows from the air guide part 22 into the first cavity, and is then sucked out by the air intake type fan 8.

[0041] In a preferred embodiment, as shown in Figures 18 to 22, the connection structure 2 includes a third connection member 29 which is an annular flange formed by extending radially from the edge of one end of the air guide section 22 away from the mounting section 23, and when the air guide section 22 is fitted into the corresponding ventilation hole 5, the third connection member 29 abuts against the surface of the foam layer 3 away from the ventilation bag 1.

[0042] In a preferred embodiment, as shown in Figures 3 and 4, the connection structure 2 includes a second connection member which is a plurality of inclined protrusions 21 spaced apart in the circumferential direction along the outer wall surface of the air guidance section.

[0043] The inclined protrusion 21 has a locking groove, and the engaging member 6 is locked in the locking groove of the inclined protrusion 21 close to the mounting portion 23 or in the locking groove of the inclined protrusion 21 away from the mounting portion 23.

[0044] Specifically, the two inclined protrusions 21 can be used separately and are complementary devices. When the assembly of the single-stage buckle (the inclined protrusion 21 closest to the foam layer 3) becomes invalid, it automatically switches to the two-stage buckle (the inclined protrusion 21 away from the foam layer 3), ensuring the stability of the fastening. When the buckle is automatically released, the buckle can be automatically reset after the passenger gets in the car for the second time.

[0045] In a preferred embodiment, as shown in FIGS. 8 to 10 and 24, the connection structure 2 includes a first connection member that is an annular inclined base 26 that is arranged in the circumferential direction along the outer wall surface of the air guidance section.

[0046] Specifically, when the air guide part 2 is fitted into the corresponding ventilation hole 5 , the connecting structure 2 is connected to the foam layer 3 by a tight fit, and the annular ramp 26 is locked onto the engaging member 6 .

[0047] Specifically, in order to prevent sharp corners from damaging the foam (excluding the parting line of the mold), it is necessary to chamfer the sharp corners of the annular ramp 26 .

[0048] Specifically, the annular ramp 26 may be one-layer, i.e., form a one-layer buckle structure (see FIG. 8, FIG. 8a is before assembly and FIG. 8b is after assembly), or two-layer, i.e., form a two-layer buckle structure (see FIG. 9, FIG. 9a is before assembly and FIG. 9b is after assembly), or even three-layer, i.e., form a three-layer buckle structure (the three-layer buckle structure in FIG. 10, FIG. 10 is an assembly diagram, FIG. 10a is before assembly and FIG. 10b is after assembly), and a cross-shaped cross structure (FIG. 12) is further provided within the annular ramp 26, which increases its strength.

[0049] Furthermore, the connection structure 2 includes a fourth connection member which is a plurality of protrusion structures 27 having locking grooves 271 and reinforcing ribs 28 arranged at intervals in the circumferential direction along the outer wall surface of the air guidance section, and when the air guidance section 22 is fitted into the corresponding ventilation hole 5, the engaging member 6 is locked in the locking groove 271.

[0050] 15-17 and 23, four protrusion structures 27 are provided, each having a reinforcing rib 28, and the locking groove 271 is engaged with an attachment on surface B of the foam layer 3. The locking groove 271 can be used separately. In this embodiment, the inclined protrusion 21 can be provided, and the inclined protrusion 21 is engaged with the inner wall of the ventilation hole 5 of the foam layer 3 by a tight fit. The inclined protrusion 21 can be used separately. The locking groove 271 and the inclined protrusion 21 are complementary devices that are simultaneously locked and fixed to ensure the stability of the lock. If the locking device becomes ineffective or the buckle is accidentally released, the buckle can be automatically reset after the occupant gets in the car for the second time.

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

[0052] Preferably, as shown in Figures 5, 6, 13, 21 and 22, the extension structure is a rubber rivet 7, and the rubber rivet 7 is attached to the hole position of the mounting hole 24 pre-arranged in the mounting portion 23, and then the fan 8 is fixed to the rubber rivet 7.

[0053] Preferably, the extension structure may further be a spring clamp 9 secured to the spring.

[0054] Preferably, the extension structure may further be a harness buckle 10 for securing an external harness of the fan 8 .

[0055] Example 2 Based on Example 1, this example provides an automobile seat, which includes a ventilation bag 1 and a foam layer 3, and the ventilation bag 1 is attached to the foam layer 3 by the above-described porous distributed sealed mounting structure for automobile seat ventilation system.

[0056] Specifically, vehicle seats equipped with this distributed vent-sealed mounting structure for automobile seat ventilation systems can improve the riding experience. The stable and efficient ventilation system can provide passengers with a sustained feeling of coolness, effectively improving seat comfort, especially in hot weather or during long drives. It also reduces the discomfort caused by humidity and makes passengers feel more relaxed and comfortable during the ride. The excellent ventilation effect reduces the accumulation of moisture and heat inside the seat, reducing the risk of deterioration and damage to the seat material caused by moisture and high temperatures. The secure mounting structure also reduces potential damage to the seat due to ventilation system failure, extending the overall service life of the automobile seat.

The above is only a preferred embodiment of the present application, where the literal expression is limited and objectively there are infinite specific structures.
