[0042] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0043] In the description of this utility model, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

[0044] Furthermore, terms such as "long," "short," "inner," and "outer" indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.

[0045] The following is in conjunction with the appendix Figure 1-5 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0046] Please refer to Figure 1 and Figure 2 This utility model provides a pillow, including a headrest part 1 and a neck rest part 2.

[0047] The headrest 1 has an adjustment notch 11, which is open on one side of the headrest 1. The neck pillow 2 is embedded in the adjustment notch 11 and is exposed to the outside of the headrest 1 through the opening side of the adjustment notch 11. The neck pillow 2 can be adjusted to be positioned on the headrest 1 through the opening side of the adjustment notch 11 to change the extension length of the neck pillow 2 relative to the headrest 1.

[0048] In some embodiments, refer to Figure 2 and Figure 3The adjustment notch 11 is recessed from the outside to the inside at the bottom of the headrest 1, and the adjustment notch 11 opens on one side of the edge of the headrest 1. At this time, the neck pillow 2 can be inserted into the adjustment notch 11. The adjustment notch 11 provides positioning for the headrest 1, so that the headrest 1 and the neck pillow 2 are connected to each other and are not easy to loosen or shift during use.

[0049] In other embodiments, the adjustment notch 11 is recessed inward from one side of the edge of the headrest portion 1, thereby forming an adjustment notch 11 with an opening on one side of the headrest portion 1. In this case, the headrest portion 1 can be inserted into the adjustment notch 11, and the adjustment notch 11 can provide positioning for the headrest portion 1, so that the two are not easy to loosen or shift during use.

[0050] It is understandable that the adjustment notch 11 is used to provide positioning for the neck pillow 2. Regardless of the specific opening method of the adjustment notch 11, as long as the embedded positioning effect is achieved, it should be included in the scope of this solution.

[0051] Based on this, a portion of the neck pillow 2 is embedded in the adjustment recess 11 to cooperate with the headrest 1. Meanwhile, another portion of the neck pillow 2 extends out to the outside of the headrest 1 through one side opening of the adjustment recess 11, and the exposed portion has a raised structure. When the user lies flat, the exposed portion of the neck pillow 2 can provide support for the user's neck to conform to the reverse curvature of the cervical spine and provide a comfortable support experience.

[0052] Furthermore, the neck pillow 2 can be adjusted relative to the head pillow 1 via the opening side of the adjustment notch 11. This allows the neck pillow 2 to move closer to or further away from the head pillow 1, thereby changing the extension length. By changing the extension length of the neck pillow 2, the neck support needs of different users can be met.

[0053] The pillow provided in this application embodiment achieves flexible neck support by constructing an adjustable neck support, meeting the neck support needs that vary from person to person, and solving the problem of inflexible neck support in pillows.

[0054] In some embodiments, continue to refer to Figure 2 and Figure 3 To allow the neck pillow 2 to be adjustablely mounted on the headrest 1, multiple slots 3 are provided at the adjustment notch 11. The multiple slots 3 are arranged at intervals along the adjustment direction of the neck pillow 2. The neck pillow 2 is provided with positioning protrusions 4 that are inserted and engaged with the slots 3.

[0055] Specifically, the slot 3 is recessed in the recessed wall of the adjustment recess 11, and the positioning protrusion 4 is located on the side surface of the neck pillow 2 facing the adjustment recess 11. When the neck pillow 2 is inserted into the adjustment recess 11, the positioning protrusion 4 is inserted into the positioning slot 3. This allows the neck pillow 2 and the headrest 1 to be mutually restricted, making it difficult for them to move relative to each other during use, thus maintaining a stable usage state and optimizing the user's actual user experience.

[0056] Based on this, users can further insert the positioning protrusion 4 into different slots 3, so that the neck pillow 2 can be mutually limited between the head pillow 1 at multiple different positions, thereby enabling the neck pillow 2 to stay stably at different extended positions and realize the position adjustment function.

[0057] It is understandable that the specific number of card slots 3 can be adjusted according to actual needs, such as two, three or four, and there is no limit to the specific number of card slots 3 here.

[0058] Alternatively, in some other embodiments, the adjustment notch 11 is provided with a plurality of positioning protrusions 4, the plurality of positioning protrusions 4 are arranged at intervals along the adjustment direction of the neck pillow 2, and the neck pillow 2 is provided with a slot 3 for the positioning protrusions 4 to be inserted and engaged.

[0059] Specifically, the positioning protrusion 4 is set in the concave wall of the adjustment recess 11, and the slot 3 is recessed on the surface of the neck pillow 2 facing the adjustment recess 11. With the cooperation of the positioning protrusion 4 and the slot 3, the neck pillow 2 and the head pillow 1 can be mutually limited to achieve a stable use state. Correspondingly, the specific number of positioning protrusions 4 can be adjusted according to actual needs, and no specific example is given here.

[0060] Therefore, regardless of the specific placement of the slot 3 and the positioning protrusion 4, as long as an insertion positioning method is used between the headrest 1 and the neck pillow 2, it should be included in the scope of this solution.

[0061] In some embodiments, in order to make the neck pillow 2 adjustable on the headrest 1, the headrest 1 is provided with a plurality of first zippers, the plurality of first zippers are arranged at intervals along the adjustment direction of the neck pillow 2, and the neck pillow 2 is provided with a second zipper that is detachably connected to the first zippers.

[0062] Specifically, the first zipper is located in the recessed wall of the adjustment notch 11, and the second zipper is located on the surface of the neck pillow 2 facing the adjustment notch 11. It can be understood that the first zipper can be installed on the headrest 1 directly or indirectly, and correspondingly, the second zipper can be installed on the headrest 1 directly or indirectly. No restrictions are placed on the specific installation method of the first zipper and the second zipper.

[0063] Based on the above settings, by connecting the first zipper and the second zipper to each other, the headrest 1 and the neck pillow 2 are fixed to each other, achieving a mutual limiting effect and making the usage state more stable. Furthermore, by connecting the second zipper to different first zippers, the adjustment function is realized.

[0064] It is understandable that the specific number of first zippers can be adjusted according to actual needs, and no limit is placed on the specific number of first zippers here.

[0065] In other embodiments, the headrest portion 1 is provided with a first Velcro fastener, and the neck pillow portion 2 is provided with a second Velcro fastener that is detachably connected to the first Velcro fastener.

[0066] Specifically, the first and second hook and loop fasteners can be silent hook and loop fasteners. The first hook and loop fastener is laid on the concave wall of the adjustment recess 11, and the second hook and loop fastener is laid on the area of ​​the headrest 1 facing the adjustment recess. In this case, the first hook and loop fastener can be set as a velvet structure and the second hook and loop fastener can be set as a hook and loop structure; or the first hook and loop fastener can be set as a hook and loop structure and the second hook and loop fastener can be set as a velvet structure.

[0067] Based on the above design, on the one hand, the headrest 1 and neck pillow 2 can be positioned in multiple locations due to the interconnection of the first and second hook and loop fasteners, thus enabling the neck pillow 2 to be adjusted for convenient use. On the other hand, the use of a silent hook and loop fastener structure effectively reduces the noise generated during the opening and closing of the first and second hook and loop fasteners, making it suitable for quiet use scenarios such as nurseries or reclining environments, thus optimizing and improving the user experience.

[0068] It is understood that the first Velcro strap can be installed on the headrest 1 by direct or indirect means, and the second Velcro strap can also be installed on the neck pillow 2 by direct or indirect means. No restrictions are placed on the specific assembly method of the first and second Velcro straps.

[0069] Alternatively, in other embodiments, the headrest 1 is provided with a plurality of first fastening positions, which are arranged at intervals along the adjustment direction of the neck pillow 2, and the neck pillow 2 is provided with second fastening positions that are detachably connected to the first fastening positions.

[0070] Specifically, the first fastener is located on the concave wall of the adjustment recess 11, and the second fastener is located on the area of ​​the headrest facing the adjustment recess. It can be understood that the first fastener can be a button or a buttonhole, and correspondingly, the second fastener can be a button or a buttonhole. For example, when the first fastener is a button, the second fastener is a buttonhole, or when the first fastener is a buttonhole, the second fastener is a button.

[0071] In addition, the specific number of the first buckle can be adjusted according to actual needs, and no limit is placed on the specific number of the first buckle here.

[0072] Based on the above settings, the headrest 1 and neck pillow 2 can be detached and fixed together by the mutual interlocking action of the first and second fasteners. On this basis, the second fastener can be fastened to different first fasteners, thereby realizing the adjustable connection between the headrest 1 and neck pillow 2. The operation is simple and quick.

[0073] Continue to refer to Figure 2 and Figure 3 The middle part of the occipital portion 1 is recessed to form a pillow 12, and a first pillow protrusion 13 and a second pillow protrusion 14 are formed on opposite sides of the pillow 12. The first pillow protrusion 13 is located on the side of the pillow 12 closer to the neck and occipital portion 2, and the second pillow protrusion 14 is located on the side of the pillow 12 away from the neck and occipital portion 2.

[0074] Based on the above configuration, the pillow 12 can support the back of the user's head, and the first pillow protrusion 13 and the second pillow protrusion 14 provide support to both sides of the back of the head to improve support stability. In addition, in one embodiment, the user's head can lean against the first pillow protrusion 13, which can be used in conjunction with the neck pillow 2 to support the user's neck, thus providing more comprehensive support. In another embodiment, the user's head can also lean against the second pillow protrusion 14, in which case the user can use the headrest 1 alone to provide different support feel needs. Thus, the structure is flexible and versatile in its use, which can meet the needs of different users.

[0075] Furthermore, the first occipital protrusion 13, the second occipital protrusion 14, and the occipital cavity 12 are transitioned by a continuous curved surface.

[0076] Based on the above settings, the continuous curved surface can provide flexible support for the user's head, thus optimizing and improving the user experience.

[0077] Furthermore, in some embodiments, the height of the second bolster 14 is greater than the height of the first bolster 13.

[0078] Based on the above settings, by setting the height of the second pillow protrusion 14 to be greater than the height of the first pillow protrusion 13, the second pillow protrusion 14 can meet the needs of some users for higher support height, while the first pillow protrusion 13 can meet the height support needs of most users. The universal performance of the pillow is optimized and improved, and the user experience is also optimized.

[0079] Reference Figure 2 The distance between the first bolster 13 and the second bolster 14 is 240mm-300mm.

[0080] It should be explained that the distance between the first occipital protrusion 13 and the second occipital protrusion 14 can be regarded as the horizontal distance between the two highest points. The distance between them also represents the overall span of the occipital cavity 12. Here, the distance between the first occipital protrusion 13 and the second occipital protrusion 14 is defined as L.

[0081] When the distance between the first pillow protrusion 13 and the second pillow protrusion 14 is less than 240mm, the pillow nest 12 will be too narrow, causing the second pillow protrusion 14 to squeeze the user's head, resulting in discomfort. When the distance between the first pillow protrusion 13 and the second pillow protrusion 14 is greater than 300mm, the support distance between the first pillow protrusion 13 and the second pillow protrusion 14 will be too large, resulting in a decrease in the support stability of the pillow. Therefore, by setting the distance between the first pillow protrusion 13 and the second pillow protrusion 14 to 240mm-300mm, both suitable comfort and good support stability can be obtained.

[0082] Optionally, the distance L between the first bolster 13 and the second bolster 14 can be 240mm, 250mm, 260mm, 270mm, 280mm, 290mm, or 300mm. It is understood that the distance between the first bolster 13 and the second bolster 14 can be set according to actual needs, and no specific restrictions are imposed here.

[0083] Furthermore, in practical applications, to enhance the user experience, pillowcases are usually provided for the headrest 1 and neck support 2. There are several ways to install these pillowcases:

[0084] In one embodiment, reference is made to Figure 4 It also includes a first pillowcase 5 and a second pillowcase 6, with the first pillowcase 5 fitted onto the headrest 1 and the second pillowcase 6 fitted onto the neckrest 2.

[0085] Specifically, the first pillowcase 5 and the second pillowcase 6 can be made of elastic knitted surface.

[0086] Based on the above settings, on the one hand, the first pillowcase 5 and the second pillowcase 6 can be made detachable, so that they can be cleaned according to the specific condition of the stains, making the disassembly and washing more flexible; on the other hand, they can provide a good tactile feel, and the user experience is optimized and improved.

[0087] It should be explained that when the headrest 1 is covered with a first pillowcase 5 and the neck pillow 2 is covered with a second pillowcase 6, in order to position the headrest 1 and the neck pillow 2 together, features such as a slot 3, a positioning protrusion 4, a first zipper, a first Velcro strap, and a first fastener are provided on the first pillowcase 5 near the adjustment notch 11; correspondingly, features such as a slot 3, a positioning protrusion 4, a second zipper, a second Velcro strap, and a second fastener are provided on the second pillowcase 6. In this way, each structure can be indirectly assembled onto the headrest 1 and the neck pillow 2 through the first pillowcase 5 or the second pillowcase 6, ultimately achieving mutual positioning between the headrest 1 and the neck pillow 2.

[0088] Alternatively, in another embodiment, refer to Figure 5 It also includes a third pillowcase 7, which is simultaneously fitted onto the headrest 1 and the neckrest 2.

[0089] Specifically, the third pillowcase 7 can also use an elastic knitted surface layer.

[0090] Based on the above settings, on the one hand, the third pillowcase 7 is designed to be removable, which makes it easy to remove and wash the third pillowcase 7 and makes it more convenient to use. On the other hand, the third pillowcase 7 can also provide a good tactile feel, and the user experience is optimized and improved.

[0091] It should be explained that when the outer sides of the headrest 1 and the neck pillow 2 are simultaneously placed inside the third pillowcase 7, features such as the slot 3, the positioning protrusion 4, the first zipper, the first Velcro, and the first fastener are directly set at the adjustment recess 11. Correspondingly, features such as the slot 3, the positioning protrusion 4, the second zipper, the second Velcro, and the second fastener are directly set on the neck pillow 2, ultimately achieving mutual positioning between the headrest 1 and the neck pillow 2.

[0092] In conclusion, whether the number of pillowcases is set to one or more, it should be included in the interpretation of this solution.

[0093] Reference Figure 5 The thickness of the neck pillow 2 gradually increases from the side closer to the head pillow 1 to the side farther away from the head pillow 1, and the concave contour of the adjustment notch 11 matches the neck pillow 2.

[0094] Based on the above settings, by setting the thickness of the neck pillow 2 to be progressively thicker, on the one hand, a raised structure can be formed to support the neck, which is ergonomic. On the other hand, as the extension distance of the neck pillow 2 increases, the height of the first pillow protrusion 13 will decrease accordingly, thus conforming to the physiological curve of the head of users with longer necks. Conversely, as the extension distance of the neck pillow 2 decreases, the height of the first pillow protrusion 13 will increase accordingly, thus conforming to the physiological curve of the head of users with shorter necks, and the ergonomic experience is significantly improved.

[0095] Reference Figure 6 A shoulder-accommodating recess 21 is provided at the edge of the neck pillow 2 away from the head pillow 1.

[0096] Specifically, there are two shoulder receiving recesses 21, which are located near the opposite sides of the neck pillow portion 2.

[0097] Based on the above configuration, when the user is lying on their side, the shoulder accommodating recess 21 can provide accommodating space for the user's shoulder to avoid discomfort caused by structural interference.

[0098] Furthermore, the headrest 1 and neck pillow 2 are made of biodegradable bio-based materials. Specifically, the raw materials of the headrest 1 and neck pillow 2 are made of environmentally friendly polymer materials extracted from plants such as soybeans and cashews using biotechnology. They are naturally biodegradable, conform to the concept of sustainable development, and are designed for low odor and low VOC control, aiming to meet general safety and environmental protection requirements such as RoHS and REACH.

[0099] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
