Description

Technical Field

[0001] This utility model belongs to the field of insole technology, specifically relating to a 3D intelligent arch cushioning insole. Background Technology

[0002] When standing, the soles of the feet bear approximately 50% of the body weight in static pressure. When walking, the instantaneous pressure on a single foot can reach 2-3 times the body weight. The elasticity of the arch of the foot can absorb more than 90% of the impact force from the ground, protecting the spine, joints, and internal organs from shock damage. If ordinary people have problems such as collapsed arches (e.g., flat feet), it can lead to misalignment of the lower limb force lines, such as the arch, calcaneus, and metatarsals, causing compensatory lesions such as knee valgus and pelvic tilt.

[0003] Insoles, as a crucial connection between the foot and the ground, primarily work in conjunction with the shoe's outsole and midsole, conforming to the shoe's shape and size chart. Ordinary insoles are flat and lack arch support. While many orthotic insoles are now used in orthopedic and rehabilitation hospitals, these products are typically medical aids, requiring custom-made designs based on the patient's arch shape. They are often expensive and unsuitable for most people with insufficient arch strength who do not meet medical criteria. Furthermore, orthotic insoles often cannot balance comfort and versatility. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a 3D arch-shaped intelligent cushioning insole, which solves the problem of mechanical support for the arch and foot in the insole in the background art, and further solves the problems of comfort and versatility of the insole.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a 3D intelligent arch cushioning insole is provided, including a main body and a surface layer; the main body has an arc-shaped bulge in the area corresponding to the arch, an air cushion is provided inside the arc-shaped bulge, and a supporting rib is provided inside the air cushion; the main body has a central bulge in the area corresponding to the palm; the outer thickness of the main body in the area corresponding to the heel is greater than the inner thickness, and several S-shaped grooves are opened laterally at the bottom of the main body in this area; the surface layer is attached to the upper surface of the main body.

[0006] In a preferred embodiment of this utility model, the main body is made of silicone material and has several vent holes.

[0007] In a preferred embodiment of this utility model, the surface layer comprises titanium silver alloy fiber cloth or graphene conductive fiber cloth.

[0008] In a preferred embodiment of this utility model, the forefoot area of ​​the main body is provided with several cutting lines, and the cutting lines have a structure in which the middle section convexes towards the toe of the shoe.

[0009] In a preferred embodiment of the present invention, the S-shaped groove protrudes towards the rear edge of the heel near the outer side of the heel and protrudes towards the arch of the foot near the inner side of the heel.

[0010] In a preferred embodiment of this utility model, the depth of the S-shaped groove is 1 / 5 to 1 / 3 of the thickness of the main body of the corresponding area of ​​the heel.

[0011] In a preferred embodiment of this utility model, the inner edge of the arc-shaped bulge is arc-shaped, the outer edge is adapted to the shape of the insole, the included angle of the tangent of the arc is 170°, and the height from the highest point of the arc-shaped bulge to the bottom surface of the main body is no more than 1.7cm.

[0012] In a preferred embodiment of this utility model, the supporting ribs are arranged vertically to divide the air cushion into several irregular slots; the top of the slots is closed and the bottom is open.

[0013] In a preferred embodiment of this utility model, the central bulge is a circular or elliptical bulge with a smooth transition between its edge and the surface of the main body.

[0014] In a preferred embodiment of the present invention, the insole is further provided with an edge, which covers the periphery of the main body and the surface layer.

[0015] This technical solution achieves overall support and cushioning for the insole through the specific structure of each functional area, and has the following advantages compared with the prior art:

[0016] 1. This solution features an arc-shaped bulge in the arch area with an internal air cushion. The air cushion contains supporting ribs, which not only ensures support for the arch but also solves the problem of insufficient elasticity after filling with a single silicone material, thus achieving arch support with elasticity and strong adaptability.

[0017] 2. This design features a central bulge in the foot area that smoothly connects with the insole surface. This bulge helps to support the foot, correct the force line, and neutralize the abruptness caused by the arch bulge, thus increasing the comfort of wearing the insole.

[0018] 3. This design features a shallow height difference in the heel area, making the outer side slightly higher than the inner side, and incorporates an S-shaped groove with a specific bending direction. This ensures the required insole thickness in the heel area while meeting the shock absorption needs of the heel during walking and reducing the overall weight of the insole.

[0019] 4. This design incorporates cuttable lines in the forefoot area to prevent the thin and soft insole from slipping and deforming during walking;

[0020] 5. This solution uses thermoplastic polyurethane elastomer silicone material and has through-holes from bottom to top. The main body can be molded in one piece, which is convenient for processing and can be cut and adjusted at will, with good adaptability.

[0021] 6. This solution involves attaching a surface layer to the main body of the insole and setting an edge binding. On the one hand, it reinforces the flexible main body to maintain its shape, and on the other hand, it reduces static electricity by using titanium silver alloy fiber cloth or graphene conductive fiber fabric, making it smoother and more comfortable to wear.

[0022] 7. The bottom of the main body of this design is equipped with anti-slip texture to prevent the insole from slipping. Attached Figure Description

[0032] Example

[0033] This embodiment of a 3D intelligent arch cushioning insole includes a main body 1, a surface layer 2, and an edging. The main body 1 is made of silicone and has several through-holes 11 extending upwards in a flat, non-functional area (0.2cm thick). The surface layer 2 is attached to the upper surface of the main body 1 and is made of titanium silver alloy fiber cloth or graphene conductive fiber fabric. The edging, approximately 0.3-0.4cm wide, covers the periphery of the main body 1 and the surface layer 2. The insole main body 1 has functional areas corresponding to the foot region, specifically including:

[0034] The main body 1 has an arc-shaped bulge 12 in the area corresponding to the arch of the foot, and an air column 13 is set inside the arc-shaped bulge 12. The inner edge of the arc-shaped bulge 12 is arc-shaped, and the outer edge is adapted to the shape of the insole. The included angle of the tangent of the arc is 170°, and the height from the highest point of the arc-shaped bulge 12 to the bottom surface of the main body 1 is no more than 1.7cm. The air column 13 is set vertically and is a cylindrical hole with a closed top and an open bottom, which is distributed inside the arc-shaped bulge 12. In this embodiment, an air cushion adapted to the shape of the arc-shaped bulge 12 is set inside the arc-shaped bulge 12. Several supporting ribs 131 are set vertically inside the air cushion 13. The supporting ribs 131 divide the air cushion 13 into several slots 132 of different heights. The top of the slot 132 is closed and the bottom is open, which not only ensures the support of the arch position, but also solves the problem of insufficient elasticity after filling with a single silicone material.

[0035] The main body 1 has a central ridge 14 in the corresponding area of ​​the palm; the central ridge 14 is a circular or elliptical ridge with a smooth transition between the edge and the surface of the main body 1, with a maximum height of about 0.5cm, which helps to support the foot, correct the force line, and avoid a large height difference caused by the direct connection between the arch ridge and the non-functional area.

[0036] The thickness (or height) H of the main body 1 on the outer side of the area corresponding to the heel is greater than the thickness (or height) h on the inner side. Several S-shaped grooves 15 are laterally formed at the bottom of the main body 1 in this area. The S-shaped grooves 15 are open at both ends and arranged side-by-side. The S-shaped grooves 15 protrude towards the rear edge of the heel near the outer side of the heel and towards the arch of the foot near the inner side of the heel. The depth of the S-shaped grooves 15 is 1 / 5 to 1 / 3 of the thickness of the main body 1 in the area corresponding to the heel. In this embodiment, the thickness of the main body 1 at the heel is 1.5 cm, the width of a single S-shaped groove 15 is approximately 0.3 cm, and the depth is 0.3-0.4 cm. A reinforcing plate 16 can also be provided on the upper surface of the main body 1 from the S-shaped grooves 15 on the outer side of the heel.

[0037] In this embodiment, the thickness of the forefoot area 1 is 0.2cm, and 5-6 cutting lines 17 are provided. The cutting lines 17 have a structure with the middle section convex towards the toe of the shoe, which can ensure the shape of the forefoot area, avoid deformation when walking, and facilitate the insertion of the insole into the shoe.

[0038] The insole of this embodiment can form a mechanical cushioning system in conjunction with the structure of the foot arch, heel bone, metatarsal bones, etc., especially providing elastic support for the arch area. Combined with the cushioning function of other areas, it intelligently adapts to the balance of most human skeletal structures and force lines, achieving good wearing comfort and universality.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
