[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0036] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0037] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0038] like Figures 1-8 As shown, a foam ventilation structure for a car seat can be used on, but not limited to, the backrest of a car seat, and can also be used on, but not limited to, the seat cushion of a car seat. It mainly includes: a foam body 1, a shielding foam 2, and a reinforcing cloth 3.

[0039] like Figure 4-Figure 5 As shown, the foam body 1 has a ventilation cavity 10 and a plurality of ventilation openings 102 connected to the ventilation cavity 10. The ventilation cavity 10 has an opening 101. Specifically, the ventilation cavity 10 is provided on the back side of the foam body 1, i.e., the B side. The plurality of ventilation openings 102 all penetrate the foam body 1. The plurality of ventilation openings 102 extend from the back side of the foam body 1 to the front side of the foam body 1, i.e., the A side. The ventilation cavity 10 is located 10 mm to 20 mm away from the B side of the foam body 1.

[0040] like Figure 1-Figure 3 as well as Figure 6-Figure 8 As shown, the shielding foam 2 is integrally formed with the foam body 1 and is disposed at the opening 101 of the ventilation cavity 10. The shielding foam 2 can shield the opening 101. An air inlet 20 is provided on the shielding foam 2 and communicates with the ventilation cavity 10. In actual use, air from the fan enters through the air inlet 20 on the shielding foam 2, passes through the ventilation cavity 10, and is blown out through the vent 102 on the foam body 1 toward the passengers.

[0041] Specifically, the connection between the foam body 1 and the shielding foam 2 of this embodiment has a rotating edge 120. The shielding foam 2 can rotate along the rotating edge 120, allowing the shielding foam 2 to be controlled to cover or expose the opening 101 in the foam body 1. Because the foam material is flexible, that is, the shielding foam 2 is a flexible member, during use, the shielding foam 2 can rotate outward along the rotating edge 120, exposing the opening 101 of the ventilation cavity 10. The shielding foam 2 can also rotate inward along the rotating edge 120, covering the opening 101 of the ventilation cavity 10.

[0042] The obstructing foam 2 of this embodiment is rectangular. It has a first side edge 21 and a second side edge 22 adjacent to the rotating edge 120, as well as an opposite side edge 23 located opposite the rotating edge 120. The first side edge 21 and the second side edge 22 are connected at both ends of the rotating edge 120 and at both ends of the opposite side edge 23. In actual use, the first side edge 21, the second side edge 22, and the opposite side edge 23 can all be attached to the foam body 1 using adhesive. Specifically, the foam body 1 is provided with a first step surface 11, a second step surface 12, and a third step surface 13, which are respectively opposite to the first side edge 21, the second side edge 22, and the opposite side edge 23. That is, the first step surface 11 corresponds to the first side edge 21, the second step surface 12 corresponds to the second side edge 22, and the third step surface 13 corresponds to the opposite side edge 23. The first side edge 21 can be fixed to the first step surface 11 by adhesive bonding, the second side edge 22 can be fixed to the second step surface 12 by adhesive bonding, and the opposite side edge 23 can be fixed to the third step surface 13 by adhesive bonding. After spraying glue on the first step surface 11, the second step surface 12, and the third step surface 13, the shielding foam 2 can be attached thereto. The fixing of the shielding foam 2 is simple and reliable.

[0043] During use, the shielding foam 2 of this embodiment is integrally formed with the foam body 1 and can be rotated along the rotating edge 120 to cover the opening 101 of the ventilation cavity 10. The shielding foam 2 is affixed to the foam body 1 with adhesive. Air from the fan enters through the air inlet 20 of the shielding foam 2, passes through the ventilation cavity 10, and is blown out through the vent 102 of the foam body 1, toward the passengers. The integrally formed shielding foam 2 and foam body 1 eliminates the need for post-attachment felt, air bags, and mullers, simplifying the assembly process and saving material and labor costs, effectively reducing costs.

[0044] Preferably, a reinforcing cloth 3 is provided on the surface of the ventilation cavity 10 along the foaming body 1 of this embodiment, and on the inner surface of the shielding foam 2. The setting of the reinforcing cloth 3 can enhance the strength of the shielding foam 2, ensuring that the shielding foam 2 will not be torn or detached from the foaming body 1 during the rotation of the shielding foam 2.
