As used in this specification and the appended claims, the singular forms "a," "an" and "the" include plural referents unless the content clearly dictates otherwise.

[0040] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in other ways different from those described herein without departing from the scope of the present application, and those skilled in the art can make similar extensions without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

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

[0042] As shown in Figure 1 , it is an unfolded state structure diagram of the neck guard body 1. The neck guard body 1 comprises an outer support layer 11 in the shape of a long strip, an inner support body 12 embedded in the outer support layer, and a support block 13 embedded in the inner support body.

[0043] As shown in Figure 2 , it is a plan view of the unfolded state of the outer support layer 11. The outer support layer 11 is a long strip of axisymmetric structure as a whole, and the edges at both ends are in the shape of a circular arc so as to be more fitted to the structure of the neck. The view shown in Figure 2 is the front. Along the extension direction of the long axis of the outer support layer 11, a plurality of first through holes 111 are provided to penetrate the outer support layer 11 front and back. The first through holes 111 include intermediate through holes 1111 provided at the middle part and end through holes 1112 provided at both ends. The intermediate through holes 1111 are axisymmetric structures, and are consistent with the axis of symmetry of the outer support layer 11. The axis of symmetry of the intermediate through holes 1111 and the axis of symmetry of the outer support layer 11 are the first axis of symmetry 14. There is one end through hole 1112 at each end of the outer support layer 11, and they are provided with the axis of symmetry of the outer support layer 11 as the axis of symmetry. Any one end through hole 1112 itself is also an axisymmetric structure, and its axis of symmetry is the second axis of symmetry 15. Alternatively, any one end through hole 1112 itself is a central symmetric structure, and its center of symmetry is at the middle position of the second axis of symmetry 15.

[0044] As shown in Figure 2As shown, in an embodiment, the outer support layer 11 is an axisymmetric structure, and the first through holes 111 include at least one middle through hole 1111 located in the middle of the outer support layer 11 and end through holes 1112 respectively located at two ends of the outer support layer 11. The middle through hole 1111 is also an axisymmetric structure and has the same axis of symmetry as the outer support layer 11. Each of the end through holes 1112 is located at one end of the outer support layer 11, and the two end through holes 1112 form an axisymmetric structure and have the same axis of symmetry as the outer support layer 11.

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