[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figure 1-6 , the present utility model provides a technical solution: a sensing insole provided with a flexible force-bearing structure, including an edge wrapping 1, a slotting 2, a sweat-absorbing pad 3, a buffer layer 4, a rebound pad 5, an airbag 6, an isolation film 7, a sensing layer 8, a pressure sensing point 9, an interlayer bag 10, and a wear-resistant layer 11.

[0031] Embodiment 1: The sensing insole is provided with a flexible force-bearing structure, so that the sweat-absorbing pad 3 fits with the rubber pad to protect the feet. Specifically:

[0032] The edge wrapping 1 is set as an irregular annular structure, and further includes a slot 2. The side surface of the edge wrapping 1 is provided with the slot 2. The edge wrapping 1 is connected with a flexible force-bearing structure, and the flexible force-bearing structure can flexibly support the sole of the foot through a rebound pad 5 when the sweat-absorbing pad 3 is pressed. The flexible force-bearing structure includes a sweat-absorbing pad 3, and the sweat-absorbing pad 3 is fixedly installed on the inner wall surface of the edge wrapping 1. The lower surface of the sweat-absorbing pad 3 is connected with a buffer layer 4, and a rebound pad 5 is embedded and connected to the upper surface of the buffer layer 4. An airbag 6 is fixedly installed on the inner wall surface of the rebound pad 5. The airbag 6 is set as an elliptical cylindrical structure, and a plurality of airbags 6 are installed at equal intervals. The rebound pad 5 is set as an irregular shape, and there are 3 rebound pads 5;

[0033] The sensing insole is provided with a sweat-absorbing pad 3. The sweat-absorbing pad 3 is arranged on the uppermost layer of the inner wall surface of the edge wrapping 1. The sweat-absorbing pad 3 can quickly absorb the sweat generated by the feet, avoid the accumulation of sweat between the insole and the feet, so as to keep the feet dry. A buffer layer 4 is connected to the lower surface of the sweat-absorbing pad 3. The rebound pads 5 embedded and installed on the upper surface of the buffer layer 4 correspond to the forefoot, the arch of the foot and the heel respectively. When walking, the rebound pads 5 will be squeezed in turn, so that the rebound pads 5 reduce the burden on the feet during exercise. The buffer layer 4 and the rebound pads 5 can effectively absorb and disperse these impact forces, reduce the damage to the foot joints, bones and soft tissues, and an airbag 6 is installed on the inner wall of the rebound pad 5. As Figure 5 shown, the airbag 6 can be adaptively adjusted according to the foot shapes and pressure distributions of different people. When the foot steps on the insole, the airbag 6 will deform according to the magnitude and direction of the pressure, so as to provide a more fitting and personalized support for the foot. During exercise, the shape and force-bearing conditions of the foot will change continuously, and the airbag 6 can respond to these changes in real time, providing dynamic support, so that the pressure sensing structure collects pressure more accurately.

[0034] Embodiment 2: The sensing insole is further provided with a pressure sensing structure, which can monitor the sole pressure in real time. Specifically:

[0035] The lower surface of the buffer layer 4 is fixedly connected with an isolation film 7. The isolation film 7 is made of an insulating material. The edge wrapping 1 is also connected with a pressure sensing structure. The pressure sensing structure can be connected to the pressure sensing points 9 through the chip hardware installed inside the sandwich bag 10 to receive pressure data. The pressure sensing structure includes a sensing layer 8. An isolation film 7 is covered and connected to the upper surface of the sensing layer 8. A plurality of pressure sensing points 9 are arranged on the upper surface of the sensing layer 8. A sandwich bag 10 is arranged on the upper surface of the sensing layer 8. A chip hardware is installed inside the sandwich bag 10, and the chip hardware is connected to the pressure sensing points 9. The lower surface of the sensing layer 8 is connected with a wear-resistant layer 11. The wear-resistant layer 11 is fixedly installed on the inner wall surface of the edge wrapping 1, and the lower surface of the wear-resistant layer 11 is flush with the lower surface of the edge wrapping 1. The side surface opening of the sandwich bag 10 corresponds to the slot 2;

[0036] Furthermore, the isolation film 7 fixedly connected to the lower surface of the buffer layer 4 covers the upper surface of the sensing layer 8. The isolation film 7 can effectively block external conductive substances and prevent them from directly contacting the electronic components in the sensing layer 8, thereby reducing the risk of short circuit. When the foot moves on the insole, friction and extrusion may occur. The isolation film 7 can play a certain physical protection role, reducing the wear of the external factors on the electronic components on the upper surface of the sensing layer 8. The isolation film 7 can buffer these acting forces and extend the service life of the electronic components. A plurality of pressure sensing points 9 are arranged on the upper surface of the sensing layer 8, which can quickly and accurately transmit the sensed pressure signals to the chip in the sandwich bag 10. The chip hardware is installed in the sandwich bag 10, and the position of the sandwich bag 10 is under the sole of the foot, ensuring the reliability and stability of the pressure signal transmission. The connection between the pressure sensing point 9 and the chip adopts advanced electronic technologies and designs, which can effectively reduce signal interference and data loss. Even in complex usage environments, such as severe vibrations and sweating during exercise, it can ensure the accurate transmission and processing of pressure data. The side surface opening of the sandwich bag 10 corresponds to the slot 2, enabling the chip hardware to be replaced according to different requirements and application scenarios. Finally, a wear-resistant layer 11 is provided on the bottom surface, which has a certain roughness or anti-slip performance, can increase the friction between the insole and the inner bottom surface of the shoe, and make the insole more stable in the shoe and not prone to displacement.

[0037] Working principle: When using the sensing insole provided with the flexible force-bearing structure, the flexible force-bearing structure is provided, so that while the sole of the foot can be adaptively supported, the pressure sensing structure is more accurately pressed, can timely sense the change of the foot pressure, and increases the overall practicability.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
