Description

Technical Field

[0001] This utility model relates to the field of neck pillow technology, and in particular to a neck pillow with a built-in airbag. Background Technology

[0002] A neck pillow is a type of pillow placed around the neck to protect the cervical spine. Medical research shows that the human cervical spine is most comfortable when maintaining its natural physiological curve. Existing neck pillows are generally too soft and lack sufficient support to effectively support the head. The user's head remains at a significant tilt angle, causing muscle stretching and compression of the cervical spine. This results in a poor overall user experience, and prolonged exposure to this position increases the risk of cervical spondylosis. While some neck pillows on the market are made with relatively firm materials to improve support, these are inconvenient to store and carry. Therefore, this application discloses a neck pillow with an internal airbag as its "soft skeleton." This design gives the central part of the neck pillow a certain inherent structure and shape, while the outer wall of the airbag is covered with soft foam material, forming a structure that is soft on the outside and firm on the inside. This provides comfort while preventing the neck pillow from collapsing due to excessive softness; furthermore, the airbag allows for easy storage after deflation. Utility Model Content

[0003] The purpose of this utility model is to provide a neck pillow with a built-in airbag. Its structure is simple and reasonable and easy to use. It uses a built-in airbag as the "soft skeleton" of the neck pillow. When the airbag is inflated, the middle of the neck pillow has a certain inherent structure and shape. The outer wall of the airbag is covered with soft foam material, forming a structure that is soft on the outside and firm on the inside. While being comfortable to use, it avoids the neck pillow from collapsing due to being too soft. At the same time, it is easy to store after the airbag is deflated.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A neck pillow with built-in airbags includes a pillowcase and a pillow core;

[0006] The pillowcase is fitted onto the outer surface of the pillow core, and the pillowcase has an opening with a zipper at the opening.

[0007] The pillow core includes a foam layer and an air bladder;

[0008] The airbag has a U-shaped structure, and the foam layer is adhered to the outer wall of the airbag;

[0009] The foamed layer has a U-shaped structure with a U-shaped cavity in its middle;

[0010] The airbag is located inside a U-shaped cavity, and its outer wall is bonded to the inner wall of the U-shaped cavity.

[0011] The process of wrapping the airbag with the foam layer requires placing the airbag in the middle of the foaming molding cavity, so that the airbag floats in the air. This ensures that the airbag is in the center of the foam layer (which is also the center of the mold cavity). To ensure that the airbag is in the center of the mold cavity, several limiting slots are provided on the front and rear sides of the airbag. The upper mold of the mold is provided with several vertically downward pins, which are inserted into the limiting slots to restrict the freedom of the airbag in the front-back (left-right) direction. At the same time, the airbag is clamped at the top and bottom ends by ejector pins, which restrict the freedom of the airbag in the vertical direction (or the bottom of the ejector pin is provided with two vertically spaced pins). This allows the airbag to float in the middle of the mold cavity, and during foaming, the foam layer can evenly cover and adhere to the outer wall of the airbag.

[0012] The upper and lower ends of the foam layer are respectively provided with needle removal holes. After the foam layer is formed, the upper mold and the lower mold are separated, and the ejector pins and insert pins are pulled out from the foam layer and the limiting groove. After the ejector pins are pulled out, needle removal holes are formed.

[0013] Preferably, the top of the airbag is provided with several arc-shaped grooves to conform to the curve of the neck;

[0014] Preferably, the top of the foam layer is provided with several arc-shaped grooves to conform to the neck curve;

[0015] Preferably, the top and bottom of the airbag are provided with ribs, which are U-shaped strip structures used to maintain its U-shaped shape.

[0016] Preferably, the airbag has an inflation port (exhaust port) and a plug. A material removal hole is provided at the corresponding foam layer position of the inflation port, exposing the inflation port, and the inflation port is connected to the plug. The inflation port is located on the side of the pillowcase zipper.

[0017] The beneficial effects of this utility model are:

[0018] Its structural design is simple and reasonable, and it is convenient to use and store. It uses an internal airbag as the "soft skeleton" of the neck pillow. When the airbag is inflated, the middle of the neck pillow has a certain inherent structure and shape. The outer wall of the airbag is covered with soft foam material, forming a structure that is soft on the outside and firm on the inside. While being comfortable to use, it prevents the neck pillow from collapsing due to being too soft. At the same time, it is convenient to store after the airbag is deflated.

Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figures 1-5 As shown, a neck pillow with built-in airbags includes a pillowcase and a pillow core 2;

[0026] The pillowcase is fitted onto the outer surface of the pillow core 2, and the pillowcase has an opening with a zipper at the opening.

[0027] The pillow core 2 includes a foam layer 3 and an air bladder 4;

[0028] The airbag 4 has a U-shaped structure, and the foam layer 3 is adhered to the outer wall of the airbag 4;

[0029] The foamed layer 3 has a U-shaped structure with a U-shaped cavity in its middle;

[0030] The airbag 4 is located inside the U-shaped cavity, and its outer wall is bonded to the inner wall of the U-shaped cavity.

[0031] The process of wrapping the airbag 4 with the foam layer 3 requires placing the airbag 4 in the middle of the foaming molding cavity so that the airbag 4 floats in the air. This ensures that the airbag 4 is in the center of the foam layer 3 (which is also the center of the mold cavity). To ensure that the airbag 4 is in the center of the mold cavity, several limiting slots 5 are provided on the front and rear sides of the airbag 4. Several vertically downward pins are provided on the upper mold of the mold. The pins are inserted into the limiting slots 5 to restrict the freedom of the airbag 4 in the front-back (left-right) direction. At the same time, the airbag 4 is clamped by ejector pins at the top and bottom ends, restricting the freedom of the airbag 4 in the up-down direction. This allows the airbag 4 to float in the middle of the mold cavity. During foaming, the foam layer 3 can evenly cover and adhere to the outer wall of the airbag 4.

[0032] The upper and lower ends of the foam layer 3 are respectively provided with needle removal holes 31. After the foam layer 3 is formed, the upper mold and the lower mold are separated, and the ejector pin and the insertion pin are pulled out from the foam layer 3 and the limiting slot 5. After the ejector pin is pulled out, the needle removal hole 31 is formed.

[0033] Preferably, the top of the airbag 4 is provided with several arc-shaped grooves 41 to conform to the curve of the neck;

[0034] Preferably, the top of the foam layer 3 is provided with a plurality of arc-shaped grooves 41 to conform to the neck curve;

[0035] Preferably, the airbag 4 has ribs 42 at its top and bottom. The ribs 42 are U-shaped strip structures used to maintain the U-shaped shape of the airbag 4. When the airbag 4 is inflated, it forms a bulging U-shaped structure with a cylindrical cross-section. When the airbag 4 is deflated, it forms a flat U-shaped structure with a vertical strip cross-section. The figure shows the structural form of the airbag 4 after deflation.

[0036] Preferably, the airbag 4 is provided with an inflation port (exhaust port) and a plug. A material removal hole is provided at the corresponding position of the foam layer 3, exposing the inflation port, which is connected to the plug. The inflation port is located on the side of the pillowcase zipper.

[0037] Preferably, the bottom of the foam layer 3 is provided with a groove 32 that matches the curvature of the shoulder shape.

[0038] Preferably, the foam layer 3 is made of materials such as memory foam or polyether polyurethane foam sponge.
