The descriptions in this section are merely illustrative and explanatory, and should not be construed as limiting the scope of protection of this application. Specifically, the described embodiments are only some embodiments of this application, not all embodiments.

[0020] It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0021] Example 1 As mentioned in the background section, in order to solve the problems existing in the prior art, this embodiment provides an automotive seat ventilation system, including: Seat foam 1, with multiple first ventilation holes 11 provided on the seat foam 1; Air guide assembly 2 is disposed on seat foam 1. The air guide assembly 2 has a first ventilation zone 101 inside, and the first ventilation zone 101 is connected to a plurality of first ventilation holes 11. Ventilation fan 3 is located on the side of air guide assembly 2 away from seat foam 1. Ventilation fan 3 is used to drive gas to flow within the first ventilation hole 11 and the first ventilation zone 101. The support structure is located on one side of the first ventilation zone 101, and the support structure can form a second ventilation zone 102 adjacent to the first ventilation zone 101 between the seat foam 1 and the ventilation fan 3.

[0022] like Figure 1 As shown, seat foam 1 is a cover for a car seat. First ventilation holes 11 are formed along the thickness direction of the backrest portion of seat foam 1 on the backrest portion, connecting a first surface of seat foam 1 near the occupant and a second surface away from the occupant. An air guide assembly 2 is fixed to the side of seat foam 1 away from the occupant. The air guide assembly 2 has a first ventilation zone 101 inside, connecting each of the first ventilation holes 11 and the ventilation fan 3. A support structure is located on one side of the first ventilation zone 101, supporting the air guide assembly 2 to form a second ventilation zone adjacent to the first ventilation zone 101. The ventilation fan 3 in the air zone 102 has an axial air inlet and a circumferential air outlet. When the air inlet of the ventilation fan 3 is connected to the air guide assembly 2, its air outlet is located outside the air guide assembly 2. The ventilation fan 3 can drive the gas from the side of the seat foam 1 closest to the human body, through the first ventilation hole 11 and the two ventilation zones, to the side away from the human body. When the air outlet of the ventilation fan 3 is connected to the air guide assembly 2, its air inlet is located outside the air guide assembly 2. The ventilation fan 3 can drive the gas from the side of the seat foam 1 away from the human body, through the two ventilation zones and the first ventilation hole 11, to the side closer to the human body.

[0023] By setting a support structure to support the first ventilation zone 101, a second ventilation zone 102 is formed on one side of the first ventilation zone 101. This allows the gas to flow within the first ventilation zone 101 and the second ventilation zone 102, driven by the ventilation fan 3. This increases the ventilation space and ventilation speed of the ventilation system, effectively avoids the problem of increased wind resistance caused by compression, and greatly improves the overall ventilation volume of the ventilation system.

[0024] Furthermore, the seat foam 1 has an installation groove 12, which is connected to a plurality of first ventilation holes 11. An air guide assembly 2 is provided at the installation groove 12. The air guide assembly 2 includes a pressure-bearing air guide 21, which is filled in the installation groove 12 to form the first ventilation zone 101.

[0025] For details, please refer to Figure 1 The mounting groove 12 is approximately a cuboid recess and is located on the second surface of the seat foam 1. All the first ventilation holes 11 are connected to the bottom of the mounting groove 12. The air guide assembly 2 is located in the mounting groove 12. The pressure-bearing air guide 21 is also approximately a cuboid structure. The pressure-bearing air guide 21 can be made of 3D spacer mesh fabric in the prior art. The 3D spacer mesh fabric has several woven mesh holes, which gives it good air permeability. The pressure-bearing air guide 21 is located in the mounting groove 12. Its own porous structure has a rectifying effect, which balances the gas pressure when the gas passes through, thereby forming the first ventilation zone 101.

[0026] Optionally, the air guide assembly 2 may adopt the structure of any of the following embodiments; correspondingly, the support structure may adopt the structure corresponding to the air guide assembly 2 in any of the following embodiments.

Specifically, the first sealing layer 22 is an elastic membrane structure made of TPU material. The first sealing layer 22 covers the opening of the mounting groove 12. The space formed by the first sealing layer 22 and the mounting groove 12 is filled with a pressure-bearing air guide 21.

[0028] Optionally, the support structure is a foamed boss 31, at least one foamed boss 31 is integrally formed in the mounting groove 12, and the free end of the foamed boss 31 abuts against the pressure-bearing air guide 21 so that a second ventilation zone 102 is formed between the pressure-bearing air guide 21 and the seat foam 1.

[0029] Specifically, the foaming protrusion 31 is fixed in the mounting groove 12 and integrally formed with the seat foam 1. The foaming protrusion 31 is offset from the first ventilation hole 11. The free end of the foaming protrusion 31 extends along the axial direction of the first ventilation hole 11 and abuts against the side of the pressure-bearing air guide 21 near the seat foam 1, so that the part of the pressure-bearing air guide 21 corresponding to the foaming protrusion 31 forms a recess away from the seat foam 1, thereby forming a second ventilation zone 102 between the seat foam 1 and the pressure-bearing air guide 21. The number and shape of the foaming protrusion 31 can be adjusted according to the actual situation and are not specifically limited here. Preferably, the length of the foaming protrusion 31 along the axial direction of the first ventilation hole 11 is greater than 10mm to ensure that the second ventilation zone 102 has sufficient space to improve the ventilation volume of the ventilation system.

[0030] Optionally, the support structure is a fastener 32, at least one fastener 32 is provided in the mounting groove 12, and the free end of the fastener 32 abuts against the pressure-bearing air guide 21 so that a second ventilation zone 102 is formed between the pressure-bearing air guide 21 and the seat foam 1.

[0031] Specifically, the fastener 32 is embedded in the seat foam 1. The fastener 32 is also offset from the first ventilation hole 11. The free end of the fastener 32 extends along the axial direction of the first ventilation hole 11 and abuts against the side of the pressure-bearing air guide 21 near the seat foam 1, so that the part of the pressure-bearing air guide 21 corresponding to the fastener 32 forms a recess away from the seat foam 1, thereby forming a second ventilation zone 102 between the seat foam 1 and the pressure-bearing air guide 21. The number and shape of the fastener 32 can be adjusted according to the actual situation and are not specifically limited here. Preferably, the length of the part of the fastener 32 extending out of the seat foam 1 along the axial direction of the first ventilation hole 11 is greater than 10mm, to ensure that the second ventilation zone 102 has sufficient space to improve the ventilation volume of the ventilation system.

[0032] Optionally, the support structure is a support air guide 33; The supporting air guide 33 is disposed between the seat foam 1 and the pressure-bearing air guide 21. The two ends of the supporting air guide 33 abut against the seat foam 1 and the pressure-bearing air guide 21 respectively, so that a second ventilation zone 102 is formed between the seat foam 1 and the pressure-bearing air guide 21. Alternatively, the supporting air guide 33 may be disposed between the first sealing layer 22 and the pressure-bearing air guide 21, with both ends of the supporting air guide 33 abutting against the first sealing layer 22 and the pressure-bearing air guide 21 respectively, so that a second ventilation zone 102 is formed between the pressure-bearing air guide 21 and the first sealing layer 22.

[0033] Specifically, the supporting air guide 33 also has a porous structure, which has good air permeability and support performance. The supporting air guide 33 can be set on either side of the pressure-bearing air guide 21 so that a second ventilation zone 102 is formed between the pressure-bearing air guide 21 and the seat foam 1 / first sealing layer 22. The supporting air guide 33 can be set on one side of the pressure-bearing air guide 21 by filling, or fixed to the pressure-bearing air guide 21 by bonding or welding.

[0034] Please refer to Figure 3-7 One embodiment of a car seat ventilation system is shown, wherein: The air guide assembly 2 also includes a second sealing layer 23, which is disposed in the mounting groove 12. The edge of the second sealing layer 23 is sealed to the edge of the first sealing layer 22. A plurality of second ventilation holes 231 are provided on the second sealing layer 23, and each second ventilation hole 231 is correspondingly connected to each first ventilation hole 11. A pressure-bearing air guide component 21 is provided between the first sealing layer 22 and the second sealing layer 23.

[0035] Specifically, the second sealing layer 23 is also made of TPU material to form an elastic membrane structure. The edge of the second sealing layer 23 is sealed and welded to the edge of the first sealing layer 22 to form an elastic bladder. The pressure-bearing air guide 21 is filled between the second sealing layer 23 and the first sealing layer 22. The second sealing layer 23 is attached to the mounting groove 12 so that each second ventilation hole 231 is connected to each first ventilation hole 11.

[0036] Optionally, the support structure is a foamed boss 31, at least one foamed boss 31 is integrally formed in the mounting groove 12, and the free end of the foamed boss 31 abuts against the pressure-bearing air guide 21 so that a second ventilation zone 102 is formed between the pressure-bearing air guide 21 and the seat foam 1. Specifically, the foamed protrusion 31 is fixed in the mounting groove 12 and integrally formed with the seat foam 1. The foamed protrusion 31 is offset from the first ventilation hole 11. A through hole 232 is opened on the second sealing layer 23 corresponding to the foamed protrusion 31. The through hole 232 is also offset from the second ventilation hole 231. The free end of the foamed protrusion 31 passes through the through hole 232 along the axial direction of the first ventilation hole 11 and abuts against the side of the pressure-bearing air guide 21 near the seat foam 1, so that the part of the pressure-bearing air guide 21 corresponding to the foamed protrusion 31 forms a recess that moves away from the seat foam 1, thereby forming a second ventilation area 102 between the second sealing layer 23 and the pressure-bearing air guide 21. The number and structure of the foamed protrusion 31 are the same as in the previous embodiment, and will not be described again here.

[0037] Optionally, the support structure is a fastener 32, at least one fastener 32 is provided in the mounting groove 12, and the free end of the fastener 32 abuts against the pressure-bearing air guide 21 so that a second ventilation zone 102 is formed between the pressure-bearing air guide 21 and the seat foam 1. Specifically, the fastener 32 is embedded in the seat foam 1. The fastener 32 is also offset from the first ventilation hole 11. A through hole 232 is opened on the second sealing layer 23 corresponding to the fastener 32. The through hole 232 is also offset from the second ventilation hole 231. The free end of the fastener 32 extends axially along the first ventilation hole 11, passes through the through hole 232, and abuts against the side of the pressure-bearing air guide 21 near the seat foam 1. This causes the part of the pressure-bearing air guide 21 corresponding to the fastener 32 to form a recess on the side away from the seat foam 1, thereby forming a second ventilation zone 102 between the second sealing layer 23 and the pressure-bearing air guide 21. The number and structure of the fastener 32 are the same as in the previous embodiment, and will not be described again here.

[0038] Optionally, the support structure is a support air guide 33; The supporting air guide 33 is disposed between the second sealing layer 23 and the pressure-bearing air guide 21. The two ends of the supporting air guide 33 abut against the second sealing layer 23 and the pressure-bearing air guide 21 respectively, so that a second ventilation zone 102 is formed between the second sealing layer 23 and the pressure-bearing air guide 21. Alternatively, the supporting air guide 33 may be disposed between the first sealing layer 22 and the pressure-bearing air guide 21, with both ends of the supporting air guide 33 abutting against the first sealing layer 22 and the pressure-bearing air guide 21 respectively, so that a second ventilation zone 102 is formed between the pressure-bearing air guide 21 and the first sealing layer 22. Specifically, the supporting air guide 33 is also a porous structure with good air permeability and support performance. The supporting air guide 33 can be set on either side of the pressure-bearing air guide 21 so that a second ventilation zone 102 is formed between the pressure-bearing air guide 21 and the second sealing layer 23 / first sealing layer 22.

Driven by ventilation fan 3, gas passes through the first ventilation hole 11 and two ventilation zones in sequence and is then drawn in through the air inlet of ventilation fan 3, and then discharged through the air outlet of ventilation fan 3 to the side of the car seat away from the human body. When the air outlet of ventilation fan 3 is sealed to the air guide assembly 2, ventilation fan 3 is activated. Driven by ventilation fan 3, gas is drawn in through the air inlet of ventilation fan 3, and then discharged through the air outlet of ventilation fan 3 into the air guide assembly 2, and then passes through the two ventilation zones and the first ventilation hole 11 in sequence before being discharged to the side of the car seat closer to the human body.
