DETAILED DESCRIPTION

[0038] The following will be combined with the implementation methods of this application to clearly and completely describe the technical solutions in the implementation methods of this application. Obviously, the described implementation methods are only part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] It should be understood that the terms used in this specification of the embodiments of the present application are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present application. As used in the specification of the embodiments of the present application and the appended claims, unless the context clearly indicates otherwise, the singular forms of "a", "an" and "the" are intended to include plural forms.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] The first aspect of the present application provides a detachable multifunctional neck guard, comprising a neck guard body 1 (such as Figure 1 As shown), a jacket 2 covering the neck guard body 1 (as shown Figure 3 , 4 As shown) and the connection structure 3 (as Figure 4 The two ends of the neck guard are connected together by a connecting structure 3 to form a surrounding support for the neck.

[0042] like Figure 1 , which is a structural diagram of the unfolded state of the neck guard body 1. The neck guard body 1 comprises an elongated outer support layer 11, an inner support body 12 embedded in the outer support layer, and a support block 13 embedded in the inner support body.

[0043] like Figure 2 , which is a plan view of the unfolded state of the outer support layer 11. The outer support layer 11 is an elongated strip with an axisymmetric structure as a whole, and the edges at both ends are arc-shaped so as to better fit the neck structure. Figure 2 The view shown is the front. Along the direction of the long axis extension of the outer support layer 11, a plurality of first through holes 111 are arranged to penetrate the outer support layer 11 from front to back. The first through holes 111 include an intermediate through hole 1111 arranged in the middle part and end through holes 1112 arranged at both ends. The intermediate through hole 1111 is an axisymmetric structure, and is consistent with the axis of symmetry of the outer support layer 11. The axis of symmetry of the intermediate through hole 1111 and the outer support layer 11 is the first axis of symmetry 14. There is one end through hole 1112 at each end of the outer support layer 11, and the axis of symmetry of the outer support layer 11 is arranged as the axis of symmetry. Any one of the end through holes 1112 itself is also an axisymmetric structure, and its axis of symmetry is the second axis of symmetry 15. Optionally, any one of the end through holes 1112 itself is a centrosymmetric structure, and its center of symmetry is in the middle of the second axis of symmetry 15.

[0044] like Figure 2As shown, in one embodiment, the outer supporting layer 11 is an axisymmetric structure, and the plurality of first through holes 111 include at least one middle through hole 1111 located in the middle of the outer supporting layer 11 and end through holes 1112 located at both ends of the outer supporting layer; the middle through hole 1111 is also an axisymmetric structure, and has the same symmetry axis as the outer supporting layer 11. There is one end through hole 1112 located at each end of the outer supporting layer, and the two end through holes 1112 form an axisymmetric structure, and the symmetry axis is the same as the symmetry axis of the outer supporting layer 11.

[0045] Specifically, the middle part of the outer support layer 11 is bent downward along the direction of the first symmetry axis 14, and the two ends of the outer support layer 11 are bent upward along the direction of the second symmetry axis 15, together forming an outer support layer 11 with curved upper and lower edges, so as to conform to ergonomics, fit the shape of the neck, and improve comfort and support. Figure 2 As shown, taking the left side of the first symmetry axis 14 as an example, the intersection A of the first symmetry axis 14 and the upper edge of the outer support layer 11 is the lowest point of the upper edge of the entire outer support layer 11, and the intersection B of the second symmetry axis 15 and the upper edge of the outer support layer 11 is the highest point of the upper edge of the entire outer support layer 11. Point O in the figure is the intersection of the first symmetry axis 14 and the horizontal line, and the angle θ is the angle between the AB line and the horizontal line, representing the curvature of the downward bend of the middle part of the outer support layer. From point B to point A, the upper edge of the outer support layer 11 forms a convex curve and slowly transitions to point A, so that the overall outer support layer 11 transitions naturally, is more ergonomic, and fits the neck. Point B is the highest point of the upper edge, and the left edge of point B bends downward to form a curved side edge, so that the side edge fits the neck better when the two ends of the neck guard are connected together. The height difference between point A and point B in the direction of the symmetry axis extension is h, and neck guards with different curvatures can be designed by adjusting the range of angle θ and height difference h.

[0046] Preferably, the angle θ is in the range of 10° to 30°, and the height difference h is in the range of 0.5 to 1.5 cm.

[0047] Specifically, the material of the outer supporting layer is natural latex, which is a thermoplastic synthetic resin of the rubber type. It is characterized by high elasticity, good film-forming properties during bonding, and flexibility of the film. As a result, the film has excellent flexural resistance, shock resistance and creep resistance, and is suitable for bonding dynamic components and bonding between materials with different thermal expansion coefficients.

[0048] Specifically, Figure 2 As shown, the upper and lower edges of the middle through hole 1111 change with the curvature of the middle of the outer supporting layer 11 , and the upper and lower edges of the middle through hole 1111 are approximately parallel to the corresponding upper and lower edges of the outer supporting layer 11 .

[0049] like Figure 1 As shown, the neck guard of the present application further comprises a plurality of detachable inner support bodies 12, which are adapted to the shapes of the plurality of first through holes 111, so that when the inner support bodies 12 are embedded in the first through holes 111, the supporting effect of the neck guard during use is enhanced.

[0050] Specifically, Figure 1 and 2 As shown in combination, the inner support body 12 includes an intermediate support body 121 and an end support body 122; the intermediate support body 121 is adapted to the number, position and edge shape of the intermediate through hole 1111, and when the intermediate support body 121 is embedded in the intermediate through hole 1111, the support of the middle part of the neck guard is enhanced; the end support body 122 is adapted to the number, position and edge shape of the end through hole 1112; when the end support body 122 is embedded in the end through hole 1112, the support of both ends of the neck guard is enhanced.

[0051] Optionally, the middle support body 121 is shaped like a rectangle with upper and lower edges bent in the same direction and four arc-shaped corners; and the end support body 122 is shaped like a square with four sides concave inward and four arc-shaped corners protruding outward. Such a shape can have both support and elasticity, thereby enhancing the softness and comfort of the neck guard.

[0052] Specifically, the material of the inner support body 12 can be polyurethane, and the compression strength is greater than that of the outer support layer. Therefore, the support is stronger than the outer support layer. The outer support layer is closer to the skin and requires a relatively soft and skin-friendly material. In order to ensure the support of the back neck and the side neck, it is necessary to design an inner support body 12 with better support at the corresponding position. Optionally, the inner support body 12 is fixedly embedded in the first through hole 111 of the outer support layer 11 by gluing or suturing to form a support structure that is soft on the outside and hard on the inside.

[0053] Specifically, Figure 2 As shown, each of the inner support bodies 12 is provided with at least one second through hole 123, and a plurality of detachable support blocks 13 are provided to match the shape of the second through hole 123, so that when the support blocks 13 are embedded in the second through holes 123, the supporting effect of the neck guard is enhanced when in use, and the support blocks 13 are detachably provided, so that the user can install or remove the support blocks 13 according to the support needs or usage scenarios during use.

[0054] In one embodiment, the support block 13 matched with the second through hole 123 of the end support body 122 is a centrally symmetrical structure, and the center of symmetry coincides with the center of symmetry of the end support body 122, so that the strength of the two ends of the neck guard body 1 is balanced; the support block 13 matched with the second through hole 123 of the middle support body 121 is a centrally symmetrical structure, and the center of symmetry is on the symmetry axis of the outer support layer 11, so that the strength of the middle part of the neck guard body 1 is balanced; the support strength of the neck guard body is adjusted by disassembling or installing the support block.

[0055] In one embodiment, a second through hole 123 is provided on each of the intermediate support bodies 121 and each of the end support bodies 122, and the shapes may be the same or different. A plurality of support blocks 13 are also provided that match the number, position and shape of the second through holes, and the support strength of the neck guard body 1 can be adjusted when the support blocks 13 are removed or installed. The shapes of the second through holes 123 and the support blocks 13 may be symmetrical structures such as squares, rectangles, circles, or irregular shapes of symmetrical structures. Preferably, the shapes of the second through holes 123 and the support blocks 13 are cross-shaped, specifically as follows Figure 1 The four corners of the square shown protrude outward to form a cross structure, which can have a certain degree of elasticity while maintaining sufficient support, thereby improving comfort.

[0056] In one embodiment, the support block 13 is made of one or more materials selected from rubber, polyurethane, an inflatable airbag, memory foam, and a polyolefin elastomer film material, and has higher compression strength and support than the inner support body 12 .

[0057] like Figure 3 As shown, the detachable multifunctional neck guard of the present application further includes a jacket 2, wherein the jacket 2 covers the neck guard body 1, and a zipper 21 is provided to facilitate taking out the neck guard body and washing the jacket 2 separately.

[0058] like Figure 4 FIG. 2 is a schematic diagram of the wraparound structure of the detachable multifunctional neck guard of the present application. A connecting structure 3 is provided at one end of the jacket 2, and the two ends of the neck guard can be wrapped around and connected to form a support for the neck. Preferably, the connecting structure can be an adjustable snap-on buckle or Velcro, which is not shown in the figure.

[0059] The outer cover 2 is closely attached to and covers the inner outer support layer 11. In the assembled state, the outline of the outer support layer can be observed from the surface of the outer cover 2. Figure 5 , which is a schematic cross-sectional view of the outer supporting layer 11 .

[0060] like Figure 5As shown, the transition between the top and bottom surfaces of the outer support layer 11 and the side surfaces is a curved transition, and an inclined surface with a certain slope is formed. Taking the surface where the top surface 23 is located as the horizontal plane, the inner side surface 25 and the outer side surface 26 are perpendicular to the top surface 23. Specifically, the upper edge of the outer support layer 11 includes a top surface 23 parallel to the horizontal plane, an inner inclined surface 22 that forms an angle with the horizontal plane and is inclined toward the inner side surface 25, and an outer inclined surface 24 that forms an angle with the horizontal plane and is inclined toward the outer side surface 26. The inner inclined surface 22 is located between the inner side surface 25 and the top surface 23 to form a connection. The outer inclined surface 24 is located between the outer side surface 26 and the top surface 23 to form a connection. The connection between the inner inclined surface 22 and the outer inclined surface 24 and the top surface 23 and the side surface is an arc connection. The arc transition makes the outer support layer as a whole fit the neck structure better and improves comfort. Similarly, the lower edge also has the same inclined surface structure as the upper edge.

[0061] Optional, such as Figure 8 , Fig. 9 and Fig.10 As shown, in the second embodiment, the neck guard body includes an outer supporting layer 11, and a plurality of slots are arranged on the outer supporting layer 11, wherein the depth of the slots is less than the thickness of the outer supporting layer 11, forming a groove 4;

[0062] The detachable inner support bodies are adapted to the shapes of the slots, so that when the inner support bodies are embedded in the slots, the supporting effect of the neck guard is enhanced during use.

[0063] When the card slot passes through the outer support layer, the card slot is the aforementioned first through hole. When the card slot does not pass through the outer support layer, but is a semi-embedded card slot, such as Figure 8 The figure is a structural diagram of the semi-embedded structure of the neck guard body of this embodiment. A plurality of semi-embedded slots, i.e., grooves 4, are arranged on one side of the outer support layer, and an inner support body adapted to and detachably connected to the semi-embedded slots is arranged. When viewed from the side, the surface of the inner support body and the surface of the outer support layer are on the same plane. When in use, the user installs or removes the inner support body as needed.

[0064] Optionally, a second slot or a second through hole is provided on the inner support body, and a support block adapted to the second slot or the second through hole is provided. The second through hole has the same features as the second through hole in the aforementioned embodiment.

[0065] Specifically, in the third embodiment, if Fig.11 , Fig.12 and Fig.13As shown, the neck guard body includes an outer support layer 11 and a fitting layer 16. The fitting layer 16 is arranged on one side or both sides of the outer support layer 11. The outer contour of the fitting layer 16 is at least partially consistent with the outer contour of the outer support layer 11, but the area is smaller than the area of ​​the outer support layer 11. The fitting layer 16 can be fixedly connected to the outer support layer 11, or it can be connected together with Velcro to form a detachable connection to meet the support needs of different users. Optionally, a plurality of fitting through holes 161 can be provided on the fitting layer 16 for placing support blocks. The shape of the support block is consistent with the fitting through hole, and the structural principle is consistent with the above-mentioned support block.

[0066] Specifically, in the fourth embodiment, if Fig.14 , Fig.15 and Fig.16 As shown, the neck guard body includes an outer supporting layer 11 and a fitting layer 16, the fitting layer 16 is arranged on one side or both sides of the outer supporting layer 11, and the outer contour of the fitting layer 16 is at least partially consistent with the outer contour of the outer supporting layer 11, but the area is smaller than the area of ​​the outer supporting layer 11. The fitting layer 16 can be fixedly connected to the outer supporting layer 11, or connected together with Velcro to form a detachable connection to meet the support needs of different users.

[0067] Specifically, in some embodiments, the card slots provided on the outer support layer 11 may be long strips, and the long strips of card slots are adapted to be matched with the long strips of support bodies 17. A plurality of strips of support bodies 17 are connected to each other to form a Fig.17 The "Z"-shaped support structure 18 shown, or Fig.18 The mesh support structure 19 shown, or Fig.19 A honeycomb support structure 20 is shown.

[0068] A second aspect of the present application is to provide a method for using a detachable multifunctional neck guard, comprising:

[0069] Unzip the jacket and remove or install support blocks according to support needs;

[0070] Determine how to wear the neck guard based on the usage scenario;

[0071] Adjust the position of the neck guard and connect the two ends of the neck guard together through the connecting structure.

[0072] Use scenarios include:

[0073] The middle support body supports the back of the neck, such as Figure 6As shown, it is suitable for riding in a vehicle or sitting for rest in daily life. When the backrest is too low to support the neck, or the backrest is too hard to support the neck, the neck protector of the present application is used to support and protect the neck. The middle support body supports the back of the neck so that the neck can lean back. At the same time, the end support bodies on both sides form limit positions on the left and right sides to prevent the head from tilting to the left or right when sitting for rest, causing abnormal neck twisting. The support area is mainly the back of the neck and the left and right sides of the cheeks.

[0074] The middle support body supports the front neck, such as Figure 7 As shown, it is suitable for working, studying or browsing on the phone to prevent the neck from being in an abnormal forward state for a long time and causing cervical health problems. The supporting area is mainly the front neck below the chin. The front neck is supported by the middle support body to prevent lowering and extending the head, adjust and correct the neck position, and help improve the health of the cervical spine.

[0075] In summary, the present application provides a detachable multifunctional neck guard, including a neck guard body, the neck guard body including: an elongated outer support layer, on which a plurality of first through holes are arranged; a plurality of detachable inner support bodies, adapted to the shapes of the plurality of first through holes, so that when the inner support bodies are embedded in the first through holes, the supporting function of the neck guard when in use is enhanced; wherein each of the inner support bodies is provided with at least one second through hole, and a detachable support block is adapted to the shape of the second through hole, so that when the support block is embedded in the second through hole, the supporting function of the neck guard when in use is enhanced.
