Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an airbag massage device and a car seat. Background Technology

[0002] When the massage airbags 2 of a car seat are installed in the foam layer 5, multiple massage airbags 2 need to be connected in series into an airbag string using connectors 4 such as TPU. The connection method is usually welding; for example... Figure 1 As shown, when the foam layer 5 is formed, a cavity 3 is left to accommodate the entire air bag string. During installation, the air bag string is embedded in the cavity 3, and both ends of the air bag string extend to the back of the foam layer 5 for fixation. The air bag string is also bonded to the bottom surface of the cavity 3 with adhesive backing.

[0003] The connector 4 is generally connected to the same side of multiple air bags. During installation, in order to ensure the flatness and firmness of the adhesive backing, the entire connector 4 needs to be flatly bonded to the bottom surface of the cavity 3. That is, the bottom surface of the entire cavity 3 is a plane, and the part of the cavity 3 that accommodates the air bags and the part that only accommodates the connector 4 (the part of the connector 4 between adjacent air bags) have the same depth.

[0004] However, this raises a problem: while the multiple massage airbags 2 are all located on one side of the connector 4, and the massage airbags 2 can completely fill the corresponding areas of the recessed cavity 3, areas outside the massage airbags 2 cannot, leaving a depression. If this depression is not addressed, the corresponding area will collapse after the seat is covered with the surface layer, affecting the overall quality of the product. Therefore, in existing technologies, a large area of ​​foam 1 is additionally filled into the recessed areas before covering the surface layer, which increases costs. Utility Model Content

[0005] The present invention aims to provide an airbag massage device and a car seat to solve the problem that existing airbag massage devices require filling with foam before covering, which increases costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an air bag massage device, comprising a foam layer, a connector, and a plurality of massage air bags. The surface of the foam layer is provided with a plurality of mutually spaced concave cavities. The connector is embedded in the foam layer and passes through the bottom surface of each concave cavity in sequence and is connected to the bottom surface of the concave cavity. The plurality of massage air bags are respectively located in each concave cavity, and the massage air bags are connected to the connectors on the bottom surface of the concave cavities.

[0007] Furthermore, the bottom of the massage air bag is provided with a connecting post, and the connector is provided with a corresponding connecting hole at the bottom surface of the concave cavity, and the connecting post and the connecting hole are engaged.

[0008] Furthermore, the connector is an elastic connector, the connecting hole is a through hole, and the connecting post is a stepped post. The connecting post passes through the connecting hole, and its steps are locked at the end of the connecting hole.

[0009] Furthermore, the end of the connecting column near the foam layer is hemispherical.

[0010] Furthermore, the end of the connecting column near the foam layer is conical.

[0011] Furthermore, the connector is compositely connected to the bottom surface of the cavity.

[0012] Furthermore, the foam layer has clearance holes at the corresponding connection holes, and the diameter of the clearance holes is larger than that of the connection holes.

[0013] Furthermore, the clearance hole is a through hole.

[0014] Furthermore, the massage air bag is a TPU air bag, and the connecting column is a plastic column, which are welded together.

[0015] The technical principle and technical effects of this utility model are as follows:

[0016] To meet the standards mentioned in the background section, existing technologies typically use another material to fill the depressions outside the airbag. Any optimization focuses on the filling material itself: for example, what materials offer better support, are more readily available and cheaper, and are easier to process; what shapes provide better overall integrity; and what filling methods are easier to implement and yield better results. No researchers have considered, or reported, the possibility of fundamentally changing the way the airbag is secured, thereby altering the overall structure of the airbag massage device. This would not only meet the standards but also reduce costs and streamline processes.

[0017] This application breaks with conventional thinking, bypassing the inevitable filling of depressions and fundamentally eliminating them. Before foaming, the connector is placed in the mold; after foaming, the connector is directly embedded within the foam layer. This results in the cavities on the surface of the foam layer being spaced apart, with the connector portion between adjacent cavities concealed and fixed within the integrally molded foam layer. The entire surface of the foam layer, except for the spaced cavities, is flat. Once the airbags fill the cavities, the entire surface of the foam layer is completely flat, eliminating the need for additional fillers to maintain flatness. This structure, when used in car seats, prevents sagging after the surface layer is applied.

[0018] In this process, the connectors sequentially pass through the bottom surfaces of each cavity, forming the airbag string mentioned in the background technology. This satisfies the requirement of stringing the airbags together as a whole. Furthermore, the flat pre-embedding of the connectors ensures that the molded connectors are in a flat state. Since the connectors are placed into the mold during foaming, they become bonded together with the molded components after foaming. This includes not only the portion of the connector located between adjacent cavities but also the portion passing through the bottom surface of the cavity. The connectors can be bonded to the bottom surface of the cavity, resulting in a stable connection and reducing the need for adhesive bonding as in existing technologies. This reduces adhesive usage, which is environmentally friendly, and also reduces the number of gluing steps, thus improving overall production efficiency.

[0019] There are many ways to connect the massage air bag and the connector, as long as the connection can be achieved. The connection method in this application is a snap-fit ​​between the connecting post and the connecting hole. This connection is convenient and can reduce the amount of glue used due to adhesive bonding, which is undoubtedly more environmentally friendly.

[0020] By employing elastic connectors and using a stepped post and through-hole snap-fit ​​method, operation becomes more convenient. Simply align the stepped post with the through-hole on the elastic connector and press it down. The stepped post will deform and expand, allowing it to pass through the through-hole and finally snap into place at the end of the connection hole. It's worth noting that the foam itself is soft and can deform under pressure, forming a cavity to accommodate the stepped post passing through the connection hole. However, for easier operation and a more secure and stable connection, clearance holes are provided in the foam layer corresponding to the connection hole to prevent the portion of the stepped post from passing through the connection hole, thus accommodating that portion. The diameter of the clearance holes is set larger than the diameter of the connection hole, allowing the stepped post to easily snap into place at the end of the connection hole. In addition, the settings can be further optimized by making the clearance hole a through hole. This is convenient for molding, and when the stepped column is pressed into the connecting hole, the air in that local space will be compressed, which will hinder the movement of the stepped column. The through hole can allow air to escape, thus avoiding this situation.

[0021] For ease of connection, this application also features a special design for the end of the connecting post near the foam layer, making it hemispherical or conical. This facilitates pressing the connecting post into the connecting hole or even the clearance hole, and serves as a guide during the pressing process.

[0022] This application also provides another technical solution, namely a car seat that includes the above-mentioned airbag massage device. Attached Figure Description

[0029] The following detailed description provides further details on specific implementation methods.

[0030] It should be understood that in the description of the specific embodiments, the terms "longitudinal", "lateral", "vertical", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0031] The reference numerals in the accompanying drawings include: 1. foam, 2. massage air bag, 3. cavity, 4. connector, 5. foam layer, 6. connecting post, 7. clearance hole, and 8. connecting hole.

[0032] Example 1:

[0033] This embodiment provides an airbag massage device, such as Figure 2 , Figure 3 As shown, the airbag massage device includes a foam layer 5, a connector 4, and several massage airbags 2. The surface of the foam layer 5 has several recesses 3, which are spaced apart from each other and arranged in a row. In this embodiment, there are four recesses 3. The connector 4 is strip-shaped and preferably made of elastic material, such as felt or TPU. In this embodiment, felt is used; specifically, a felt strip.

[0034] The connector 4 is embedded within the foam layer 5, achieved by pre-embedding it within the mold before foaming. The connector 4 is laid flat inside the foam layer 5, passing sequentially through the bottom surfaces of the four recesses 3 and forming a composite connection with the bottom surfaces of the recesses 3. That is, when viewed from above, the connector 4 is visible, yet it is also connected to the bottom surfaces of the recesses 3. This connection is achieved in one step during foaming, eliminating the need for a separate bonding process after foaming. Therefore, when viewed from above, the final massage device shows the spaced connectors 4, with the foam layer 5 separating the connectors 4.

[0035] The connector 4 is provided with a connecting hole 8 at the center of each cavity 3. The connecting hole 8 is a through hole. The foam layer 5 is provided with a clearance hole 7 at the position of each connecting hole 8. The clearance hole 7 is also a through hole. The clearance hole 7 is formed simultaneously during foaming. The clearance hole 7 is coaxial with the connecting hole 8, and the diameter of the clearance hole 7 is larger than the diameter of the connecting hole 8.

[0036] In this embodiment, there are four massage air bags 2, each located within one of the four recessed cavities 3. Each massage air bag 2 has a connecting post 6. In this embodiment, the connecting post 6 is a stepped post with one step. The diameter of the step closer to the foam layer 5 is larger than the diameter of the other step. Figure 4 As shown, the end of the connecting post 6 near the foam layer 5 is hemispherical. In this embodiment, the connecting post 6 is a plastic post to ensure its rigidity; while the massage air bag 2 in this embodiment is a TPU air bag; the connecting post 6 and the air bag are welded together.

[0037] The connecting post 6 passes through the connecting hole 8, and its step is engaged at the end of the connecting hole 8, while the larger diameter step extends into the clearance hole 7 of the foam layer 5, thereby realizing the connection between the massage air bag 2 and the connector 4.

[0038] The airbag massage device in this embodiment is implemented as follows: Before the foam layer 5 is formed, the connector 4 is placed in the molding mold, and then the foam is formed. In this way, the formed foam is stably embedded in the foam layer 5. Then, the massage airbags 2 of this embodiment are sequentially placed into the various cavities 3 of the foam layer 5 and pressed firmly towards the foam layer 5 until the step of the connecting post 6 is stuck at the end of the connecting hole 8. In this way, the massage airbags 2 are connected in series into a whole, and the connector 4 is also laid flat and connected in the foam layer 5, which not only meets the standard requirements, but also reduces the production cost.

[0039] This embodiment also provides a car seat, such as Figure 5As shown, the car seat includes the aforementioned airbag massage device. Specifically, this embodiment includes two airbag massage devices, namely two rows of concave cavities 3 and corresponding massage airbags 2; the foam layers 5 of the two airbag massage devices are integrally formed, together serving as the foam layer 5 of the car seat backrest.

[0040] Example 2:

[0041] The only difference between this embodiment and Embodiment 1 is that the end of the connecting column 6 near the foaming layer 5 is conical, such as... Figure 6 As shown, the rest is the same as in Example 1.

[0042] For those skilled in the art, without departing from the concept of the present utility model, several modifications and improvements can be made, and these should also be considered within the scope of protection of the present utility model. These will not affect the effectiveness of the implementation of the patent or the practicality of the patent.
