Technical Field
[0001] This application generally relates to the field of automotive seat technology, and specifically to an automotive seat foam structure and an automotive seat. Background Technology
[0002] As people's demands for seating comfort continue to increase, massage and ventilation devices are becoming increasingly common in modern seat designs. However, in existing seat designs where the seat foam incorporates both massage and ventilation devices, the air ducts or air bags required for the massage device can lead to a loss of airflow, thus affecting ventilation performance; especially in existing designs, the large opening size results in a significant loss of airflow.
[0003] In existing technologies, baffle structures (including foam baffles, air jacket sponge rings or rubber rings, wrapping tape, etc.) are usually set on the foam on both sides of the air duct groove to form a barrier. Although this method can reduce air volume loss to some extent, it increases the number of parts and manufacturing processes, thereby increasing production costs and complexity. Utility Model Content

[0032] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.
[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0034] Example 1
[0035] Please refer to Figures 1-11 This application provides a car seat foam structure, comprising:
[0036] The foam body 1 is equipped with a ventilation device and a massage device, wherein the ventilation device is located on the side of the foam body 1 away from the human body.
[0037] The massage device includes: an air-using component 2 disposed on the side of the foaming body 1 close to the human body, and an air source component disposed on the side of the foaming body 1 away from the human body; the air-using component 2 and the air source component are connected by an air pipe 5.
[0038] Placement hole 3 is provided through the foam body 1, and air pipe 5 is provided through the placement hole 3. In this embodiment, air pipe 5 is a hollow tubular structure, and at least part of the outer wall of air pipe 5 is circumferentially abutted against the inner wall of placement hole 3, so as to prevent the ventilation device from communicating with the space of the foam body 1 near the human body through placement hole 3, thereby causing air volume loss.
[0039] Specifically, such as Figure 3 As shown, in this embodiment, a plurality of air-using components 2 are provided on the side of the foaming body 1 close to the human body. Each air-using component 2 is individually connected to the air source component through an air pipe 5. The air pipe 5 is used to pass the gas pumped out by the air source component. In this embodiment, the air-using component 2 is a massage air bag. The air source component includes an air pump for supplying air and a controller for distributing airflow.
[0040] Specifically, in this embodiment, at least a portion of the outer wall of the trachea 5 is in circumferential contact with the inner wall of the placement hole 3. For example, a section of the outer wall of the trachea 5 is in circumferential contact with the inner wall of the placement hole 3, or the entire outer wall of the trachea 5 is in circumferential contact with the inner wall of the placement hole 3.
[0041] In some embodiments, at least one airflow channel is provided through the foam body 1 along a first direction, and the airflow channel is connected to a ventilation device; the first direction is perpendicular to the back of the car seat; wherein, the ventilation device includes a fan 7 and a ventilation bag 9, the ventilation bag 9 is disposed on the side of the foam body 1 away from the human body, the ventilation bag 9 is formed by welding the edges of two layers of membrane structure, the membrane structure can be a TPU film or other films with similar properties, the ventilation bag 9 is filled with an air guiding structure, usually a 3D spaced mesh fabric, which has several woven mesh holes and a certain thickness, with good breathability and support, and can guide airflow through, and can also ensure ventilation effect when squeezed by the human body, the ventilation bag 9 has multiple air distribution holes on the side near the foam body 1, and the air distribution holes are connected to the airflow channel 8 one by one; the other side of the ventilation bag 9 is provided with a fan 7, and the fan 7 is connected to the ventilation bag 9; when the fan 7 is activated, the outside air is drawn in and delivered to the surface of the seat through the ventilation bag 9 and the airflow channel 8 in sequence to provide a comfortable riding experience and keep the seat surface dry and at a suitable temperature;
[0042] Working principle: Since at least part of the outer wall of the air tube 5 is circumferentially abutted against the inner wall of the placement hole 3, the foam structure at the placement hole 3 can tightly abut against the outer wall of the air tube 5, thereby blocking the connection between the seat A and B surfaces at the placement hole. The airflow generated by the fan 7 during operation will not leak at the placement hole 3, but will all flow through the airflow channel 8 on the foam to the passenger's back area. This avoids the problem in the prior art where some airflow is lost through the placement hole 3 after flowing out of the ventilation bag 9. In this way, not only can ventilation performance be guaranteed and a continuous and stable ventilation effect be provided to avoid insufficient airflow, but the user's physical comfort can also be enhanced; and no additional parts or processes are added.
[0043] In some embodiments, the placement hole 3 includes a windproof part 4, which is disposed inside the placement hole 3 and abuts against the outer wall of the air pipe 5.
[0044] Specifically, such as Figure 1 and Figure 2 As shown, the placement hole 3 includes a windbreak part 4, which is integrally formed with the foam body 1 during foaming. In this embodiment, the windbreak part 4 is disposed inside the placement hole 3 and abuts against the outer wall of the air pipe 5 to block the excess channels in the placement hole 3, preventing airflow from flowing out after entering the placement hole 3 when the ventilation device is in use, thus causing a loss of air volume. In this way, ventilation performance can be guaranteed, providing a continuous and stable ventilation effect without adding extra processes, saving costs.
[0045] In some embodiments, the windbreak 4 is an annular structure and is disposed in the middle of the placement hole 3. Of course, it can also be disposed in other positions of the placement hole 3. This application does not make specific limitations. The windbreak 4 has a through hole in the middle that matches the air pipe 5. The air pipe 5 passes through the through hole in the middle of the windbreak 4, and the outer wall of the air pipe 5 abuts against the inner wall of the windbreak 4.
[0046] In some embodiments, the width of the placement hole 3 near the gas source assembly is smaller than the width of the placement hole 3 near the gas consumption assembly 2, and the inner wall of the placement hole 3 near the gas source assembly abuts against the two side walls of the gas pipe 5 respectively.
[0047] Specifically, such as Figure 4 and Figure 5 As shown, the width of the placement hole 3 near the air source component is smaller than the width of the placement hole 3 near the air-using component 2. That is, in this embodiment, the placement hole 3 has a shape that is narrower at the back and wider at the front. The inner wall of the placement hole 3 near the air source component is circumferentially abutted against the outer wall of the air pipe 5, that is, the airflow is blocked from entering the placement hole 3 from the entrance position of the placement hole 3, preventing the airflow from flowing into the placement hole 3 when the ventilation device is in use, thus preventing the loss of air volume. Moreover, even if the passenger's sitting posture is tilted to one side and the side wing of the seat is squeezed, only the front end of the placement hole 3, that is, the wider end, will expand, while the rear end of the placement hole 3, that is, the narrower end, will remain unchanged, or even become tighter, still ensuring a good airflow blocking effect. In this way, ventilation performance can be guaranteed, providing a continuous and stable ventilation effect.
[0048] In some embodiments, the placement hole 3 is located near one end of the gas source assembly, where the extrusion pipe 5 is positioned.
[0049] Specifically, such as Figure 6 and Figure 7 As shown, the placement hole 3 is positioned near the end of the air source component to compress the air pipe 5. In this embodiment, the entrance of the placement hole 3 is slit-shaped. The air pipe 5 is generally made of TPU tubing, which has a certain degree of rigidity. When passing through the slit, the air pipe 5 will not be squeezed shut, and the slit of the placement hole 3 can be tightly attached to the outer wall of the air pipe 5 to achieve a good effect of blocking airflow and further prevent the loss of air volume of the ventilation device.
[0050] In some embodiments, the inner diameter of the placement hole 3 matches the outer diameter of the trachea 5, and the outer wall of the trachea 5 circumferentially abuts against the inner wall of the placement hole 3.
[0051] Specifically, such as Figure 8 and Figure 9 As shown, the inner diameter of the placement hole 3 matches the outer diameter of the air pipe 5, and the outer wall of the air pipe 5 circumferentially abuts against the inner wall of the placement hole 3. That is, the air pipe 5 completely fills the internal space of the placement hole 3 to prevent airflow from flowing into the placement hole 3 when the ventilation device is in use, thus preventing loss of air volume.
[0052] Example 2
[0053] Please refer to Figure 3 and Figure 11 As shown, this application provides an automobile seat, including the seat foam structure of any one of Embodiment 1.
[0054] Specifically, such as Figure 3 and Figure 11 As shown, this application provides a car seat, in which the seat foam provided in any of Embodiment 1 is installed on the car seat. The air-supply component 2 of the massage device is located on side A of the foam body 1, i.e., the side closer to the human body, while the air source component is located on side B of the foam body 1, i.e., the side farther from the human body. The two are connected by an air pipe. A ventilation device is also located on side B of the foam body 1, enabling the coordinated operation of the ventilation device and the massage device. Furthermore, because the outer wall of the air pipe 5 circumferentially abuts against the inner wall of the placement hole 3, airflow loss caused by the connection between the ventilation device and the placement hole 3 is effectively avoided. This design ensures stable ventilation performance, maintains a continuous and constant ventilation effect, prevents insufficient airflow, and improves the user's comfort level, without adding any extra parts or processes, thus balancing functionality and economy.
