The main structure is composed of buffer structures 61 and buffer mechanisms 71 staggered and arranged in a ring shape.

[0030] Working principle: The reverse trapezoidal structure 21 is a downward driving device, and its surface is compressed and resettable and foldable. The reverse trapezoidal structure 21 has the characteristic of being folded and hardened under force, so that it exhibits strain hardening behavior under the compression of impact force. The surface of the reverse trapezoidal structure 21 is a smooth curved surface, which is conducive to the upward dispersion and downward gathering of force. When the lower side is compressed, it is compressed inward to force the inner side to expand the contact area, disperse the force and achieve a buffering effect, thereby reducing the impact force. The positive trapezoidal structure 31 has the same characteristics as the reverse trapezoidal structure 21. When compressed, the force is dispersed downward and gathered upward. The cross-sectional size is equal to the reverse trapezoidal structure 21. Two first flexible beams 42 crossing at forty-five degrees are provided in the middle of the middle-layer cross-spring type flexible hinge 41, and the two second flexible beams 42 are forty-five degrees. The upper and lower first connecting plates 43 are connected by two flexible beams 42 and can rotate around the d-axis. The first middle-layer cross-spring type flexible hinge 41 with the characteristic of being resettable after bending has a connecting plate cross-sectional size of the positive trapezoidal structure 21. The lower side cross-section of the trapezoidal structure 31 has the same arc radius of f, and two flexible beams 52 crossing at forty-five degrees are arranged in the middle of the second middle cross-spring type flexible hinge 51. The two flexible beams 52 are forty-five degrees, and the upper and lower second connecting plates 53 are connected by the two flexible beams 52 and can rotate around the d axis. The second middle cross-spring type flexible hinge 51 has the characteristic of being resettable after bending, and the cross-sectional size of its connecting plate is the same as the upper side cross-section of the positive trapezoidal structure 31, and the arc radius is g; the buffer structure 61 composed of the upper reverse trapezoidal structure 21, the second middle cross-spring type flexible hinge 51, and the lower positive trapezoidal structure 31, the buffer mechanism 71 composed of the upper positive trapezoidal structure 31, the first middle cross-spring type flexible hinge 41, and the lower reverse trapezoidal structure 21, the buffer structure 61 and the buffer mechanism 71 are staggered and arranged in a ring to form a structural main body 11, which has the characteristics of being resettable after compression and being resettable after bending. The composite structure can be made of plastic material, which is easy to clean and lightweight and breathable.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
