[0002] To adapt to the needs of users, footwear design has been continuously developing in order to find and determine technical solutions that can provide people with the best comfort.

[0003] In a patent document with a published patent number of "CN113389830A" and a patent name of "Shock-absorbing Spring and Insole", a shock-absorbing spring is disclosed, and the shock-absorbing spring has the following characteristics: it includes a plurality of spring units arranged in sequence, the spring unit is formed by bending an elastic wire, the spring unit has a first buffer portion, a second buffer portion, and an upper support portion and a lower support portion arranged at intervals in the front and rear, the first end of the first buffer portion is connected to the upper support portion disposed on the front side, the second end of the second buffer portion is connected to the lower support portion disposed on the rear side, the first end of the second buffer portion is connected to the upper support portion, and the second buffer portion is connected to the lower support portion of the spring unit adjacent to the rear side. In this patent, an external object or a human body comes into contact with the shock-absorbing spring, and the shock-absorbing spring is subjected to external loads. The spacing between each spring unit becomes smaller, and the upper support part moves toward or away from the lower support part. Twisting occurs between the first buffer part and the upper support part and between the first buffer part and the lower support part. The spring unit stores deformation energy through elastic deformation, thereby achieving a buffering and shock-absorbing effect in the longitudinal direction; each upper support part comes into contact with and supports the object, so that the force is evenly applied to each part of the object, thereby improving the overall supporting effect and buffering effect of the shock-absorbing spring.

[0004] However, there is such a situation: when the user walks, the foot applies downward pressure to the shock-absorbing spring, the upper support part moves downward under the force, and the spring unit will continuously restore the distance between the upper support part and the lower support part through its deformation ability. Over time, the distance between the upper support part and the lower support part gradually decreases, the deformation ability of the spring unit deteriorates, the shock-absorbing spring loses its buffering and shock-absorbing effect, and the life of the shock-absorbing spring is reduced.

[0028] In the embodiment of the present utility model, Figure 1 and Figure 2This case provides a buffer spring insole, including a spring body 100, the spring body 100 includes a plurality of groups of spring units 110 arranged in sequence, the spring unit 110 includes a first support bar 120, a second support bar 130, a first elastic support portion 140 and a second elastic support portion 150. The first support bar 120 and the second support bar 130 are arranged up and down, the first support bar 120 and the second support bar 130 both have a first end and a second end, the first elastic support portion 140 connects the first ends of the first support bar 120 and the second support bar 130, and the second elastic support portion 150 connects the second end of the first support bar 120 and the second end of the second support bar 130 of the adjacent spring unit 110. It also includes a buffer pad 200, a limiting ring 210 extending from the edge of the buffer pad 200, the limiting ring 210 and the buffer pad 200 form an installation cavity 220, and the spring body 100 is installed in the installation cavity 220; the buffer pad 200 is provided with a plurality of transversely arranged protrusions 230, a recessed groove 240 is formed between the two protrusions 230, and the second supporting cross bar 130 abuts against the upper end of the recessed groove 240.

[0029] Specifically, when the insole is subjected to pressure, it can provide more uniform and effective buffering through the synergistic effect of multiple spring units 110. At the same time, the first support bar 120 and the second support bar 130 divide the spring body 100 into an upper and lower two-layer structure, so that the spring body 100 has a good support and elastic buffering effect. The protrusion on the buffer pad 200 is used to abut against the spring unit 110, and the recessed groove 240 is used to place the second support bar 130. When the user's foot presses down to apply pressure to the buffer spring insole, the first elastic support part 140 and the second elastic support part 150 are deformed by force, and the first support bar 120 moves in the deformation direction, and the protrusion 230 abuts against the first elastic support part 140 and the second elastic support part 150, so that the two stop deforming under the reverse support force, thereby limiting the movement stroke of the first support bar 120. With this design, the spring body 100 has a buffering and shock-absorbing effect while enhancing the life of the spring body 100.

[0030] In another embodiment of the utility model, Figure 1-3As shown, the protrusion 230 includes a front end face 231 and a rear end face 232; the front end face 231 is arranged perpendicular to the buffer pad 200, and the rear end face 232 is arranged obliquely downward, and the first elastic support portion 140 and the second elastic support portion 150 are both subjected to force to abut against the rear end face 232. Specifically, due to the structural design of the first elastic support portion 140 and the second elastic support portion 150 of the next spring unit 110, when pressed down and deformed, both are deformed toward the rear end face of the protrusion 230, and the first support bar 120 also approaches in its direction, and the rear end face 232 of the protrusion 230 abuts against the first elastic support portion 140 and the second elastic support portion 150, so as to prevent the first elastic support portion 140 and the second elastic support portion 150 from further deformation, and the first support bar 120 also moves further. The rear end surface 232 of the protrusion 230 is tilted downward, which supports and limits the first elastic support part 140 and the second elastic support part 150, ensures that the protrusion 230 is not easily deformed under pressure, and enhances the durability of the buffer spring insole.

[0031] In another embodiment of the utility model, Figure 1-3 As shown, the angle between the front end face 231 and the rear end face 232 is an acute angle, and the supporting capacity of the protrusion 230 is optimal within the range of 0-90 degrees.

[0032] In another embodiment of the utility model, Figure 2 As shown, the front end and the rear end of the buffer pad 200 are both provided with abutting ends 300, and the front end and the rear end of the spring body 100 are both abutted against the abutting ends 300. Specifically, the front end and the rear end of the buffer pad 200 are provided with abutting ends 300, and the front end and the rear end of the spring body 100 are received in the front end and the rear end of the installation cavity 220, so that the front end and the rear end of the spring body 100 are not easily damaged by the outside world.

[0033] In another embodiment of the utility model, Figure 3 As shown, the end of the rear end face 232 is kept at an equal distance from the front end face 231 of the next protrusion 230. Specifically, since the spring unit 110 is deformed when pressed down, the second support bar 130 at the bottom is easy to slide off, and the end of the rear end face 232 of the protrusion 230 is kept at an equal distance from the front end face 231 of the next protrusion 230 to form a concave groove 240, which can ensure that the second support bar 130 is not easy to detach; and the spring body 100 is formed by bending a steel wire, and the adjacent second support bars 130 are kept at the same distance, so the end of the rear end face 232 of the protrusion 230 is kept at an equal distance from the front end face 231 of the next protrusion 230, which is conducive to preventing the second support bar 130 from sliding out.

[0034] In another embodiment of the utility model, the transverse length of the protrusion 230 is adapted to the shape of the spring body 100, that is, the buffer pad 200 is designed according to the shape of the spring body 100. The buffer pad 200 can protect the spring body 100 from external collisions, resulting in reduced durability.

[0035] In another embodiment of the utility model, the protrusion 230 is made of a hard material, preferably TPU material. TPU material has high load-bearing capacity, impact resistance and shock absorption performance, and can effectively protect the internal structure and product safety.

[0036] In another embodiment of the utility model, Figure 3 As shown, the first elastic support portion 140 and the second elastic support portion 150 have the same height, so that all the first support bars 120 are on the same plane, and all the second support bars 130 are on the same plane, thereby achieving planar support for the human foot.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
