Description

Technical Field

[0001] This utility model relates to the field of insole technology, and in particular to an insole with a compressed air bladder. Background Technology

[0002] As an important component of shoes, insoles have become increasingly diverse in function. Traditional insoles primarily serve to cushion, absorb sweat, and improve comfort within the shoe. However, with the increasing demands for sports and foot health, the functions of ordinary insoles are no longer sufficient.

[0003] During exercise, the feet endure significant pressure and impact, which can lead to foot fatigue, pain, and even injury. While some existing cushioning insoles can reduce impact to some extent, their cushioning effect is limited, and their performance gradually declines with prolonged use. Furthermore, ordinary insoles cannot be flexibly adjusted to suit different sports scenarios and individual needs.

[0004] Therefore, there is a need to develop a new type of insole that can provide more efficient and durable cushioning performance and can be adjusted according to actual conditions to meet people's higher requirements for foot protection and comfort. Utility Model Content

[0005] The purpose of this application is to provide an insole with a compressed air bladder to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: an insole with a compressible airbag, comprising an upper insole and a lower insole located below the upper insole;

[0007] The first cushioning airbag has two symmetrically fixedly installed on the top of the lower insole at the corresponding position of the foot.

[0008] The second cushioning airbag is provided and fixedly installed at the top of the lower insole at the corresponding position of the heel;

[0009] An annular compressed gas airbag is fixedly installed in an annular groove near the edge of the top of the lower insole to supply air to the first and second cushioning airbags.

[0010] A first pressure sensor is fixed to the top of the first cushioning airbag to detect pressure at the sole of the foot.

[0011] The second pressure sensor is fixed to the top of the second cushioning airbag to detect pressure at the heel.

[0012] A controller, embedded inside the lower insole, is used to control the air intake and exhaust of the first and second cushioning airbags.

[0013] Preferably, the first buffer airbag is connected to the annular compressed gas airbag through a first connecting pipe, and a first airflow valve electrically connected to the controller is fixedly installed on the first connecting pipe.

[0014] Preferably, the second buffer airbag is connected to the annular compressed gas airbag through a second connecting pipe, and a second airflow valve electrically connected to the controller is fixedly installed on the second connecting pipe.

[0015] Preferably, the upper insole includes an upper bamboo charcoal fiber pad and a silicone pad fixed to the lower end of the bamboo charcoal fiber pad.

[0016] Preferably, an inflation valve connected to an annular compressed gas bladder is fixedly installed on one side of the lower insole, and the inflation valve is electrically connected to a controller.

[0017] Preferably, a deflation valve is fixedly installed on one side of the lower insole, which is connected to the first cushioning airbag and the second cushioning airbag respectively, and the deflation valve is electrically connected to the controller.

[0018] In summary, the technical effects and advantages of this utility model are as follows:

[0019] By placing two first cushioning airbags at the corresponding position on the sole of the foot and a second cushioning airbag at the corresponding position on the heel, precise cushioning can be provided for the pressure characteristics of different areas. The first and second pressure sensors detect the pressure at the sole and heel in real time, and the controller controls the air intake and exhaust of the first and second cushioning airbags, so that the cushioning effect is dynamically adjusted according to the actual pressure conditions, effectively reducing the pressure on various parts of the foot, reducing the risk of sports injuries, and improving wearing comfort.

[0020] An annular compressed gas bladder is fixedly installed in an annular groove near the edge of the top of the lower insole, providing a stable gas supply to the first and second cushioning air bladders. This annular design not only makes full use of the insole space but also distributes the gas evenly, ensuring that each cushioning air bladder receives the necessary gas in a timely manner, thus guaranteeing efficient and stable cushioning performance.

[0030] Example: Manufacturing Process and Assembly

[0031] Component manufacturing

[0032] Insole making: First, prepare a bamboo charcoal fiber pad 12 and a silicone pad 13. Cut the bamboo charcoal fiber material into a suitable insole shape, and use a mold to injection mold the silicone material into a silicone pad 13 that matches the bamboo charcoal fiber pad 12. Then, use glue or hot pressing to fix the silicone pad 13 to the lower end of the bamboo charcoal fiber pad 12 to form the upper insole 2.

[0033] Insole manufacturing: The insole 1 is made of materials with a certain strength and flexibility, such as plastic or rubber. During the manufacturing process, an annular groove is made at the top of the insole 1 near the edge to install the annular compressed gas bladder 3; space is also reserved for embedding the controller.

[0034] Airbag fabrication: The first airbag 4 and the second airbag 5 are made of elastic rubber material. The rubber material is molded into a closed cavity using a mold, ensuring good sealing performance.

[0035] Sensor and valve fabrication: Suitable pressure sensors are selected as the first pressure sensor 6 and the second pressure sensor 7 to ensure accurate pressure detection. The first airflow valve 9, the second airflow valve 11, the inflation valve 14, and the deflation valve 15 are electronically controlled airflow valves to ensure precise control of gas inflow and outflow.

[0036] Component assembly

[0037] Two first cushioning airbags 4 are symmetrically fixedly installed on the top of the lower insole 1 at the corresponding position of the foot, and a second cushioning airbag 5 is fixedly installed on the top of the lower insole 1 at the corresponding position of the heel.

[0038] Place the annular compressed gas bladder 3 into the annular groove at the top of the lower insole 1 and ensure that it is securely fixed.

[0039] The first buffer airbag 4 is connected to the annular compressed gas airbag 3 using the first connecting pipe 8, and the first airflow valve 9 is installed on the first connecting pipe 8; the second buffer airbag 5 is connected to the annular compressed gas airbag 3 using the second connecting pipe 10, and the second airflow valve 11 is installed on the second connecting pipe 10.

[0040] The first pressure sensor 6 is fixed to the top of the first airbag 4, and the second pressure sensor 7 is fixed to the top of the second airbag 5, and they are electrically connected to the controller.

[0041] Install the inflation valve 14 on one side of the lower insole 1 and connect it to the annular compressed gas bladder 3; install the deflation valve 15 on one side of the lower insole 1 and connect it to the first cushioning bladder 4 and the second cushioning bladder 5 respectively, and electrically connect the inflation valve 14 and the deflation valve 15 to the controller.

[0042] Finally, place the upper insole 2 over the lower insole 1 to complete the assembly of the entire insole.

[0043] Work process

[0044] Initial inflation: The inflation valve 14 is opened by the controller, and an external inflation device is used to inflate the annular compressed gas bladder 3 through the inflation valve 14, so that the annular compressed gas bladder 3 stores a certain amount of compressed gas, which is ready to supply air to the first buffer bladder 4 and the second buffer bladder 5.

[0045] Pressure detection and regulation

[0046] When a person wears shoes equipped with this insole and walks or exercises, the first pressure sensor 6 detects the pressure at the ball of the foot, the second pressure sensor 7 detects the pressure at the heel, and transmits the detected pressure signal to the controller.

[0047] If the first pressure sensor 6 detects excessive pressure at the foot, the controller will open the first airflow valve 9, allowing gas from the annular compressed gas bladder 3 to enter the first buffer bladder 4 through the first connecting pipe 8, increasing the air pressure inside the first buffer bladder 4 and improving the cushioning performance at the foot; when the pressure returns to normal, the controller will close the first airflow valve 9.

[0048] Similarly, if the second pressure sensor 7 detects excessive pressure at the heel, the controller will open the second airflow valve 11, allowing the gas in the annular compressed gas bladder 3 to enter the second buffer bladder 5 through the second connecting pipe 10, increasing the air pressure in the second buffer bladder 5 and improving the cushioning performance at the heel; when the pressure returns to normal, the controller will close the second airflow valve 11.

[0049] Deflator operation: When it is necessary to reduce the air pressure inside the first buffer airbag 4 or the second buffer airbag 5, the controller controls the deflation valve 15 to open, so that the gas inside the first buffer airbag 4 or the second buffer airbag 5 is discharged, thereby reducing the air pressure.

[0050] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
