The following examples are only used to illustrate the possible implementation aspects of the present invention, but they are not intended to limit the scope of protection of the present invention, and are described first.

Please refer to FIG. 1 to FIG. 8, which show an embodiment of the present invention. The buffer structure of the present invention includes a body 1.

In more detail, the body 1 is provided with a first surface 2 and a second surface 3, defining a distance from the first surface 2 to the second surface 3 as a predetermined thickness, and a plurality of recesses are provided on the first surface 2 The first hole 21 has a plurality of second holes 31 recessed on the second surface 3, and the plurality of first holes 21 and the plurality of second holes 31 are all located within the predetermined thickness. Wherein, the side walls 212 of the plurality of first holes 21 are integrally and continuously connected to the plurality of first holes The side walls 312 of the two slots 31, in other words, the side wall 212 of the first slot 21 is composed of the side walls 312 of the second slot 31, and vice versa. Therefore, when subjected to an external force (such as the impact of a collision) (Gravity when riding), the side walls 212, 312 that are directly subjected to the force can transmit the distributed force synchronously and quickly, which can avoid stress concentration.

In more detail, the main body 1 is made of a soft and elastic material (such as rubber), and the plurality of first holes 21 and the plurality of second holes 31 are arranged in a staggered manner, which makes the main body 1 more general It has a multi-grid staggered structure. When external force is applied, the side walls 212 of the plurality of first holes 21 and the side walls 312 of the plurality of second holes 31 can have enough space to deform, so as to achieve the effects of shock absorption and cushioning. Please further refer to Figures 7 and 8 to illustrate with a partial structure. When an external force is applied to the first surface 2, the side walls 212, 312 will bend and deform in the direction of the external force, and they are generally in the shape of "ㄑ" ( It is like the bending of the legs of the human body) to absorb and disperse external forces to achieve the purpose of cushioning. In addition, when the external force is removed, the main body 1 can rebound to the initial state, so as to ensure that it can have a cushioning effect when used next time. In addition, if a part of the side walls 212, 312 are broken, due to the multi-grid staggered structure, the side walls 212, 312 with other sound structures can also maintain sufficient supporting force to ensure that the plurality of first holes 21 and the plurality of second holes The two-hole slot 31 retains a certain space size, and can continuously provide a buffering effect.

It is worth mentioning that when the body 1 is covered with a kit (such as a leather case) for use, the side walls 212, 312 will simultaneously squeeze each of the first holes 21 and each of the second holes during the deformation process. When the air in the hole 31 is squeezed in a certain space, its fluid characteristics will produce viscous resistance, which can increase the cushioning effect.

Preferably, the edge 211 of the plurality of first holes 21 and the bottom wall 313 of the plurality of second holes 31 are integrally and continuously connected. In addition to improving the overall structural strength, the first surface 2 is more The continuous and smooth surface has more contact area with foreign objects (such as the buttocks of the human body), so as to more evenly distribute the force and provide uniform cushioning. In the same way, it can be further designed that the edge 311 of the plurality of second holes 31 and the bottom wall 213 of the plurality of first holes 21 are integrally and continuously connected.

Preferably, the body 1 further includes a plurality of conductive grooves 4, and the opening direction of each of the conductive grooves 4 is transverse to the opening direction of each of the first hole grooves 21, and each of the conductive grooves 4 is located in the first hole groove. Between the side wall 212 of the second hole 31 and the side wall 312 of the second hole 31, the opening of one end of each of the conductive grooves 4 is opened in the side wall 212 of the first hole 21, and the opening of the other end of each of the conductive grooves 4 is The side wall 312 of the second hole 31 is opened, and each of the conductive grooves 4 communicates with the first hole 21 and the second hole 31. This allows air to circulate freely between the plurality of first holes 21 and the plurality of second holes 31 to increase air permeability, so as to quickly disperse heat without heat accumulation, and ensure better comfort. In this embodiment, each of the conducting grooves 4 extends along the direction of the predetermined thickness to form a long and narrow shape, allowing gases at different depths to circulate at the same time.

More preferably, the bottom wall 213 of each first hole 21 is provided with a first through hole 214, and the first through hole 214 communicates with the first hole 21 and the outside. The bottom wall of each second hole 31 A second through hole 314 is formed through 313, and the second through hole 314 communicates with the second hole groove 31 and the outside. It can be understood that the plurality of conducting grooves 4 provide lateral gas flow, and the first through hole 214 and the second through hole 314 further provide gas vertical flow, so as to provide gas to circulate in more directions, and more Good breathability.

In this embodiment, the plurality of first holes 21 and the plurality of second holes 31 have the same shape and size, therefore, the first surface 2 and the second surface 3 can provide the same cushioning effect when in use .

More specifically, one side wall 212 of the first hole 21 is connected to the four side walls 312 of the second hole 31, and each of the first holes 21 gradually moves from the first surface 2 to the second surface 3. When shrinking, each of the second hole grooves 31 is tapered from the second surface 3 toward the first surface 2, and each of the first hole grooves 21 and each of the second hole grooves 31 are conical. In addition, each of the first through holes 214 and each of the second through holes 314 has a circular shape. When the main body 1 is manufactured by injection molding, the circular shape facilitates smooth demolding.

More specifically, the ratio of the maximum radial dimension of the opening of each first hole 21 to the maximum value of the predetermined thickness is between 0.8 and 0.9, and the diameter of the first through hole 214 is equal to that of the first hole. The ratio of the opening diameter of 21 is between 0.2 and 0.4. It should be added that the first side 2 and the second side 3 are in parallel It is not limited to being arranged in parallel, nor is it limited to a plane (it can be any curved surface), so the predetermined thickness can be varied rather than fixed.

In summary, the buffer structure of the present invention can effectively disperse the external force and take into account the structural strength through the design that the side walls of the first holes are integrally connected to the side walls of the second holes. In addition, the design of the conduction groove, the first and second through holes can allow the gas to circulate smoothly in each of the first hole groove, the second hole groove and the outside with excellent air permeability and improve comfort.
