Detailed Description

The technical solution of the present invention will be further described in detail with reference to the following detailed description, but the present invention is not limited thereto.

Example 1:

as shown in fig. 1-3, a shock attenuation running shoes, include the shoes body 1, fix the outsole 2 in the shoes body 1 bottom, outsole 2 is equipped with the opening and upwards arranges inner chamber 3, be equipped with in proper order in the inner chamber 3 and be used for the shock-absorbing buffer layer 4 of sole, be used for the shock-absorbing torsional spring module of heel, the torsional spring module is including fixing at the fixed axle 11 of inner chamber 3, around the first swing arm 8 of fixed axle 11 luffing motion, winding torsional spring 9 on fixed axle 11, the downside at inner chamber 3 bottom and first swing arm 8 is fixed respectively to the upper and lower extreme of torsional spring 9, first swing arm 8 and the shoes body 1 bottom fixed connection.

The implementation principle is that the buffer layer 4 and the torsion spring module are arranged to respectively perform targeted shock absorption on the sole and the heel so as to meet different stress conditions, most of force is concentrated on the heel in the general walking process, and the compression and rebound effects at the position are particularly required to be enhanced; during initial state, first swing arm 8 is under the elasticity of torsional spring 9, prop up the bottom of the shoes body 1, the foot steps on the bottom of the shoes body 1, push down first swing arm 8, can descend around fixed axle 11 luffing motion because of first swing arm 8, the absorbing effect of buffering has been reached, torsional spring 9 is compressed, the back is lifted up to the heel, torsional spring 9 rebounds rapidly and resumes, promote first swing arm 8 and prop up the bottom of the shoes body 1 again, with the duty cycle of treating next time, adopt the compression of mechanical type and the mode of resilience, it can resume fast after the damping to realize running shoes slow compression, provide powerful support and feel.

In practical application, the first swing arm 8 is of a T-shaped structure, the horizontal end of the first swing arm 8 is arranged at one side far away from the fixed shaft 11, and the upper end of the torsion spring 9 is fixedly connected with the horizontal end of the first swing arm 8; the first swing arm 8 is arranged in the middle of the fixed shaft 11, and the torsion springs 9 are respectively arranged on two sides of the first swing arm 8.

In order to improve the resilience effect of the first swing arm 8, the contact area of the first swing arm 8 and the bottom of the shoe body 1 is increased, the contact area of the first swing arm 8 and the torsion springs 9 is increased, and when the contact area is increased, two or even a plurality of torsion springs 9 can be arranged to provide stronger resilience; in order that the first swing arm 8 is in the lifting process everywhere, the atress is even, provides good comfort and stability, first swing arm 8 sets up the middle part position of fixed axle 11, and torsional spring 9 divides and establishes in the both sides of first swing arm 8.

In specific implementation, the upper end and the lower end of the torsion spring 9 are correspondingly provided with a first bend 10 and a second bend 12 for increasing the contact area, the first bend 10 is fixedly connected with the bottom of the inner cavity 3, and the second bend 12 is fixedly connected with the lower side of the first swing arm 8.

The purpose of setting up is, through the mode that sets up bend 10, increases the area of contact at the torsional spring 9 both ends to improve firm in connection intensity, all act on first swing arm 8 with the torsion of torsional spring 9 simultaneously, improve the resilience effect.

In practical use, the torsion spring module further comprises a sleeve 7 in rotating fit with the fixed shaft 11, and a second swing arm 6 fixed on the sleeve 7; the second swing arm 6 and the first swing arm 8 are identical in structure, the second swing arm and the first swing arm are arranged on two opposite sides of the sleeve 7 in a mirror image mode, and the first swing arm 8 is fixedly connected with the outer wall of the sleeve 7.

The sleeve 7 is arranged, the first swing arm 8 is fixed on the sleeve 7, and the sleeve 7 rotates on the fixed shaft 11, so that the first swing arm 8 swings up and down around the fixed shaft 11; the second swing arm 6 is arranged and used for limiting the lifting swing amplitude of the first swing arm 8, and the first swing arm 8 and the second swing arm 6 swing in opposite directions due to the fact that the mirror images are arranged on the two opposite sides of the sleeve 7; in an initial state, the first swing arm 8 props up the bottom of the shoe body 1, and the second swing arm 6 tightly props up the bottom of the inner cavity 3; when the first swing arm 8 descends to the bottom of the inner cavity 3, the second swing arm 6 ascends and tightly pushes the bottom of the shoe body 1 to achieve the limiting effect, the bottom of the shoe body 1 has a certain thickness, and the shoe body does not have a stabbing feeling.

The first swing arm 8 is arranged on one side far away from the buffer layer 4 and accords with the stress distribution of feet.

The buffer layer 4 is of a wavy structure, and wave crests on the upper side and the lower side of the buffer layer 4 are fixedly connected with the shoe body 1 and the bottom of the inner cavity 3 respectively.

The buffer layer 4 achieves the buffering effect by utilizing the wavy structure of the buffer layer 4, and elastically deformable spaces are reserved between the wavy structure of the buffer layer 4 and the bottoms of the shoe bodies 1 and the inner cavities 3, the buffer layer 4 generally adopts TPU elastic plastic parts, and the soles of feet step on the bottoms of the shoe bodies 1, so that the buffer layer 4 is pressed downwards, the buffer layer 4 is elastically deformed, the heights of the upper side and the lower side are reduced, and the effect of compression buffering and shock absorption is achieved.

Further improvement, still be equipped with in the inner chamber 3 and be used for dragging the telescopic band 5 that first swing arm 8 rose, telescopic band 5 is fixed between buffer layer 4 and first swing arm 8.

The modified purpose is, through setting up elastic telescopic band 5, utilizes the extension and the shrink characteristic of telescopic band 5, pulls first swing arm 8, makes first swing arm 8 accelerate to recover, and first swing arm 8 is located the upside of fixed axle 11, and buffer layer 4 and first swing arm 8 are fixed respectively at the both ends of first swing arm 8.

The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be equivalent replacement modes, and all are included in the scope of the present invention.
