Technical Field
[0001] The utility model relates to the field of 3D printing, and more specifically, to a 3D printed U-shaped pillow. Background Art
[0002] As people's pace of life accelerates and their working methods change, neck health issues are becoming increasingly prominent. Working and studying with the head down for long periods of time and overusing electronic devices put tremendous pressure on the neck, and the need for neck care has become more urgent.
[0003] People are increasingly aware of the importance of neck health and expect to prevent and alleviate neck diseases through effective neck protection measures. However, existing neck protection products and technologies have many shortcomings. On the one hand, traditional neck protection products are relatively simple in design and often cannot adapt well to the differences in neck shape and size of different people, resulting in poor fit and inability to provide accurate support and protection. Many neck protection products have fixed shapes and cannot be flexibly adjusted according to the actual situation of individuals, which limits their applicability. On the other hand, in terms of material selection, some neck protection products may have problems such as poor air permeability and hard texture, which are not comfortable to wear, and long-term use may cause skin discomfort and other problems. Moreover, some existing neck protection devices are difficult to relax and soothe the neck muscles while providing support, and cannot fully meet the needs of neck protection. In addition, traditional manufacturing processes have difficulties in meeting personalized needs, and cannot quickly and efficiently tailor neck protection products for different individuals. These shortcomings often make people feel troubled when looking for suitable neck protection solutions, and cannot effectively solve neck health problems. Utility Model Content
[0004] The utility model aims to overcome at least one defect of the above-mentioned prior art and provide a 3D printed U-shaped pillow, which is used to provide a U-shaped pillow that is more comfortable, breathable and has better support.
[0005] The technical solution adopted by the utility model is:
[0006] The utility model provides a 3D printed U-shaped structure, wherein the U-shaped pillow is an overall U-shaped structure, and the U-shaped pillow comprises an outer skin layer with a hollow structure, and an inner support layer arranged in the outer skin layer to support the outer skin layer;
[0007] The inner support layer is composed of a 3D printed lattice, and the outer skin layer and the inner support layer are integrally printed;
[0008] The U-shaped pillow comprises two shoulder pillow parts forming the left and right sides of the U-shaped structure, and a backrest part connecting the rear ends of the two shoulder pillow parts and forming the middle connecting part of the U-shaped structure;
[0009] The front end of the upper surface of each shoulder pillow portion is set as a face fitting area, and the rear end is set as a neck fitting area, and an arc-shaped raised first hump is set between the face fitting area and the neck fitting area; a second arc-shaped raised hump is set at the connecting end of each shoulder pillow portion and the backrest portion.
[0010] By arranging a hollow elastic 3D printed lattice structure inside the U-shaped pillow and restricting it with a hollow outer skin layer on the outside, the U-shaped pillow has good elasticity and air permeability; at the same time, the corresponding parts on the shoulder pillow parts on both sides are respectively set as the face fitting area and the neck fitting area, and the first hump and the second hump are set to make it easier to limit the head during actual use of the U-shaped pillow, thereby improving stability. At the same time, when the head leans against the shoulder pillow parts on both sides, the first hump and the second hump can provide certain support for the head, and the face fitting area and the neck fitting area are recessed downward by means of the arc-shaped protrusions of the first hump and the second hump, so that they can fit well with the face and the neck respectively, thereby greatly improving the comfort of the U-shaped pillow.

[0023] Compared with the prior art, the beneficial effects of the utility model are:
[0024] 1. The U-shaped pillow of the utility model is a U-shaped structure as a whole, and is integrally formed by 3D printing. The interior is an elastic inner support layer composed of a hollow 3D printed lattice, and the exterior is an outer skin layer with a hollow structure.

[0031] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.
[0032] Example 1
[0033] like Figure 1 and Figure 2 As shown, this embodiment provides a 3D printed U-shaped pillow, which is U-shaped as a whole, and includes an outer skin layer 100 with a hollow structure, and an inner support layer 200 arranged in the outer skin layer 100 to support the outer skin layer 100; wherein the inner support layer 200 is composed of a 3D printed lattice, and the outer skin layer 100 and the inner support layer 200 are printed and formed in one piece;
[0034] by Figure 1As a reference, the U-shaped pillow includes two shoulder pillows 110 on the left and right sides of the U-shaped structure of the U-shaped pillow, and a backrest 120 connecting the rear ends of the two shoulder pillows 110 and forming the middle connecting part of the U-shaped structure; in this embodiment, in order to better fix the U-shaped pillow on the human neck, as Figure 4 As shown, the U-shaped structure of the U-shaped pillow is symmetrical on the left and right, and the two shoulder pillow parts 110 are in a certain arc shape, bending toward the inside of the U-shaped structure, corresponding to the shape of the human neck, "wrapping" the neck, and can better fit the neck.
[0035] like Figure 1 As shown, in accordance with the ergonomic structure and the headrest habit, the front end of the upper surface of each shoulder pillow portion 110 is set as a face fitting area, so that when the human head leans to the left front and right front, the human face can lean against the face fitting area, so that the U-shaped pillow fits and supports the face; correspondingly, the rear end of the upper surface of each shoulder pillow portion 110 is set as a neck fitting area, so that when the human head leans to the left and right sides, the human neck can lean against the neck fitting area, so that the U-shaped pillow fits and supports the neck;
[0036] Further, such as Figure 1 , Figure 2 and Figure 3 As shown, an arc-shaped first hump 111 is provided between the face fitting area and the neck fitting area of each shoulder pillow 110, and an arc-shaped second hump 112 is provided at the connection end of each shoulder pillow 110 and the backrest 120. The face fitting area and the neck fitting area, and the neck fitting area and the backrest 120 are separated by the first hump 111 and the second hump 112 respectively; because the first hump 111 and the second hump 112 are both arc-shaped, the first hump 111 and the second hump 112 form an arc-shaped depression with the corresponding first hump 111 and the second hump 112 in the process of separating the face fitting area and the neck fitting area, and the neck fitting area and the backrest 120, so that the head can be better limited and the head can be better fitted with the head when resting on the corresponding area, thereby improving the comfort of the U-shaped pillow. At the same time, the protrusions of the first hump 111 and the second hump 112 can provide certain support for the face, thereby improving the stability of the head when leaning against the U-shaped pillow.
[0037] In this embodiment, if Figure 4As shown, the upper surface of the outer skin layer 100 is set as a solid bonding layer 130, and the rest of the outer skin layer 100 is set as a breathable layer 140 composed of a polygonal mesh structure, and a plurality of breathable holes 131 are set on the solid bonding layer 130. In a preferred embodiment, the setting of the solid bonding layer 130 is set according to ergonomics and people's pillow habits. Specifically, the solid bonding layer 130 of the pillow part 120 is set on the upper surface of the pillow part 120, and the solid bonding layer 130 of the shoulder pillow part 110 is set on the inner side of the upper surface of the U-shaped structure of the shoulder pillow part 110, so as to improve the contact between the head and the corresponding part of the solid bonding layer 130 when the head rests on the U-shaped pillow, and further improve the comfort of the U-shaped pillow.
[0038] Preferably, the thickness of the solid bonding layer 130 is the same as the thickness of the breathable layer 140 , which can facilitate the integrated printing and molding of the U-shaped pillow while reducing printing materials to a certain extent.
[0039] In this embodiment, the front ends of the two shoulder pillows 110 are respectively provided with connection structures 113, and the connection structures 113 are used to set adjustable connectors. By setting the connection structures 113 and the adjustable connectors, the fit between the U-shaped pillow and the neck can be better adjusted, which facilitates the fixation and fit of the U-shaped pillow.
[0040] In a preferred embodiment, at least two connecting holes can be set on the connecting structure 113, and the two connecting holes are connected by a through structure that passes through the interior of the shoulder pillow portion 110. Correspondingly, the adjustable connecting piece can be set as a connecting rope or connecting belt with an adjustment fixing mechanism, such as an elastic buckle. The adjusting connecting piece realizes the connection of the two shoulder pillow portions 110 through the connecting holes and the through structure of the two shoulder pillow portions 110, so that the U-shaped pillow can be better fixed around the neck of the human body, and the degree of fit between the U-shaped pillow and the neck can be well adjusted; wherein, the inner wall of the through structure is provided with a solid inner layer, which can prevent the adjusting connecting piece from wearing the interior of the shoulder pillow portion 110 during the adjustment process.
[0041] In a preferred implementation of this embodiment, the 3D printed lattice can be set as a body-centered lattice structure, one of the body-centered lattice structures includes a plurality of lattice beams, one end of the plurality of lattice beams of the body-centered lattice structure is connected to each other to form a body center, and the other end of the plurality of lattice beams of the body-centered lattice structure is correspondingly connected to other body-centered lattice structures. The body-centered lattice structure has a simple structure and has very good elasticity and support, which can make the elastic support inner layer have good elasticity and support, and improve the comfort of the neck protector.
[0042] Correspondingly, the mesh structure can be set as a hexagonal mesh structure. The hexagonal mesh structure can be well matched with the body-centered lattice structure, convenient for printing and forming with the elastic support inner layer, and the hexagon has good ductility and can well maintain the shape of the neck guard.
[0043] It should be noted that the structure of the 3D printed lattice and the shape of the grid structure can be set according to the actual parameters of the specific U-shaped pillow.
[0044] Furthermore, in this embodiment, if Figure 3 As shown, the bottoms of the two shoulder pillows 110 are both arched structures that are open in the left and right directions, that is, they are concave upwards. The bottom of the shoulder pillow 110 is set as an arched structure and is open in the left and right directions. When the U-shaped pillow is set, it can fit well with the shoulders, improving the comfort of the U-shaped pillow.
