Description

Technical Field

[0001] The utility model relates to the field of insoles, in particular to a protective insole foam. Background Art

[0002] The structure of a pair of sports shoes can be divided into the upper, insole, midsole and outsole. These parts are usually made of flexible materials, which are comfortable to wear and can wrap and cushion the feet. The insole is generally made of foam punching.

[0003] However, the protective performance of flexible materials for the feet is not ideal, especially in the arch area, which is prone to twisting due to lack of sufficient support, causing injuries to the wearer. A common solution is to set a mid-waist protective plate at an important part of the sports shoe, but the mid-waist protective plate does not directly fit the arch of the foot, and the support and protection of the arch of the foot is still insufficient. The purpose of the utility model is to propose a foam for preparing insoles to solve the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide a protective insole foam to solve the problems mentioned in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a foam main body, an arch pad and a support block, the shape of the arch pad is the same as the shape of the orthographic projection of the arch of the foot on the insole, the arch pad is regularly placed on the foam main body in a matrix shape and connected to the foam main body, the support block includes a flexible shell and a non-Newtonian fluid filled in the flexible shell, and the top surface of the support block is connected to the bottom surface of the arch pad.

[0006] In order to optimize the above technical solution, further measures are taken: the support block is in the shape of a cone with a larger top and a smaller bottom. The asymmetric structure can improve the support block's ability to respond to external forces. Such a structural support block can reduce the impact of the support block on the bending performance of the foam insole while supporting the arch of the foot.

[0007] As a further improvement of the above technical solution: the support blocks are distributed in columns and are respectively located on the inner side, the middle part and the outer side of the arch pad. The column-like distribution can improve the bending performance of the foam-supported insole along the width direction of the insole.

[0008] As a further improvement of the technical solution: along the inner side of the arch pad to the outer side of the arch pad, the size of the support blocks in different rows gradually increases, and the height of the human arch gradually increases from the outside to the inside. This design is intended to improve the matching of the insole and the physiological structure of the arch, and to improve the support performance for the outer side of the arch.

[0009] As an improvement to the aforementioned technical solution: the sizes of the support blocks in different rows gradually increase from the inner side of the arch pad to the outer side of the arch pad. This design is intended to improve the matching between the insole and the physiological structure of the arch, and to improve the support performance for the outer side of the arch.

[0010] Furthermore: the support blocks are oriented in the same direction and their regular distribution ensures the arch support performance of the support blocks while helping the bending flexibility of the insole.

[0011] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0012] The utility model provides a protective insole foam, which supports the arch of the foot by arranging regularly distributed support blocks, thereby improving the protection during wearing and preventing the wearer's arch from being sprained due to insufficient support. In addition, the support blocks are independent of each other and will not interfere with the deformation of the insole, which can provide protection without affecting the wearing comfort and sportiness of the insole.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example

[0020] See also Figure 1-3The utility model provides a protective insole foam, comprising a foam body 1, an arch pad 2 and a support block 3. The shape of the arch pad 2 is the same as the positive projection shape of the arch of the foot on the insole. The arch pad 2 is regularly placed on the foam body 1 in a matrix shape and connected to the foam body 1.

[0021] The support block 3 is in the shape of a truncated cone that is larger at the top and smaller at the bottom. The support block 3 includes a flexible shell 301 and a non-Newtonian fluid filled in the flexible shell 301. The top surface of the support block 3 is connected to the bottom surface of the arch pad 2 and the support blocks 3 are oriented in the same direction. The support blocks 3 are distributed in columns and are respectively located on the inner side of the arch pad 2, the middle part of the arch pad 2 and the outer side of the arch pad 2. From the inner side of the arch pad 2 to the outer side of the arch pad 2, the sizes of the support blocks 3 in different columns gradually increase.

[0022] The non-Newtonian fluid refers to a fluid in the prior art that does not satisfy Newton's experimental law of viscosity, and the shear stress and shear strain rate are not in a linear relationship. It belongs to the prior art content and is known to those skilled in the art, so no further explanation of its specific composition and working principle will be given. In implementation, technicians can select non-Newtonian fluid layers of different compositions according to actual needs, which will not have a substantial impact on the technical effect.

[0023] Working principle: The foam is cut to form an insole according to the position of the arch pad 2 on the foam body 1. The arch pad 2 matches the arch of the foot. During wearing, the arch pad 2 can support the arch of the foot to avoid sprains and improve the protection of the wearer's foot.

[0024] When the wearer's foot lands on the ground, the support block 3 is subjected to an instantaneous impact, and the viscosity of the non-Newtonian fluid will increase to improve the support of the insole to the arch of the foot, which can improve the protection of the foot during exercise to avoid sprains. At the same time, since the supporting blocks 3 are independent of each other, they will not affect the bending flexibility of the insole while playing a supporting role.

[0025] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
