[0046] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.

[0047] Below is a combination of the following drawings 1- Figure 8The specific implementation of the embodiment of the present application is further explained.

[0048] See also Figure 1a-Figure 1c According to an embodiment of the present application, an insole 1 comprises:

[0049] The main body 11 is configured to be in a shape that matches the sole, and the main body 11 includes at least one accommodating groove, which is provided at a position corresponding to the forefoot and / or at a position corresponding to the heel. The embodiment of the present application includes two accommodating grooves, namely the forefoot accommodating groove 111 and the heel accommodating groove 112. Of course, only the forefoot accommodating groove 111 or only the heel accommodating groove 112 may also be provided.

[0050] The main body 11 further includes an air bag 12 corresponding to the receiving groove, and a pressure sheet 13 .

[0051] The airbags 12 are respectively disposed in at least one accommodating groove. The airbags 12 contain inert gas to support the airbags 12 to fill the accommodating groove and provide support and rebound to the forefoot and the heel respectively.

[0052] The pressure sheet 13 is disposed between the airbag 12 and the accommodating grooves 111 , 112 , so that the airbag 12 is pressed downward as a whole in a planar shape and rebounds as a whole.

[0053] The airbag in the embodiment of the present application matches the shape of the sole and is not easy to rupture, and the insole can be applied to various sports scenes.

[0054] In long-distance sports scenarios such as marathons, the airbag needs to bear a large pressure and is prone to rupture. However, the pressure plate 13 shares the pressure that the airbag needs to bear to the pressure plate, protecting the airbag and avoiding damage to the human body caused by the rupture of the airbag, so that the embodiment of the present application can be applied to multiple sports scenarios.

[0055] The shape of the pressure sheet 13 in the embodiment of the present application is adapted to the upper surface of the airbag 12 , and fully or partially covers the surface of the airbag 12 that contacts the receiving groove.

[0056] The inert gas in the airbag 12 is nitrogen, which keeps the temperature of the airbag 12 stable during running, reduces the possibility of bursting, and also reduces blisters on the soles of the feet caused by excessive friction in the shoes.

[0057] See also Figure 1a-Figure 1c If the pressure sheet 13 partially covers the middle position of the airbag, it can better avoid the occurrence of local contact force loss and increase the rebound efficiency.

[0058] Specifically, the pressure sheet 13 is attached to the upper surface of the airbag 12 through the snap-fit ​​buckles at both ends of the receiving grooves (forefoot receiving groove 111; heel receiving groove 112). Grooves are arranged at both ends of the receiving groove, and the snap-fit ​​buckles have protruding ends, which are arranged in the grooves to achieve snap-fit, so that the pressure sheet 13 is fixed to the upper surface of the airbag 12, avoiding the friction of the protrusions caused by the installation of the pressure sheet 13 on the sole of the foot.

[0059] Specifically, see Figure 1a The pressure sheet 13 is attached to the upper surface of the airbag 12 by bonding, so that the pressure sheet 13 is fixed to the upper surface of the airbag 12 to avoid friction of the protrusion caused by the installation of the pressure sheet 13 on the sole of the foot.

[0060] The pressure sheet 13 is made of carbon plate material, and its shape is adapted to the strip or other shapes on the surface of the airbag. Since the carbon plate material can provide resilience, the pressure sheet made of carbon plate material can further increase the resilience of the insole.

[0061] In some specific implementations of the embodiments of the present application, the insole 1 further includes a receiving groove (not shown in the figure) arranged at the arch position, an air bag 12 corresponding to the receiving groove, and a pressure plate 13.

[0062] Since some users have flat feet, they usually use special flat foot insoles to adjust their walking or running posture. The embodiment of the present application uses a receiving groove (not shown in the figure) and an air bag 12 and a pressure sheet 13 arranged at the arch position to provide additional support for the arch, which can effectively improve the muscle leverage caused by flat feet and improve body defects.

[0063] In some specific implementations of the embodiments of this application, see Figure 2 as well as Figure 3 , the airbag 12 comprises:

[0064] The gas charging and discharging valve 121 comprises a valve cover 1211, a valve body 1212 and a valve cavity 1213 arranged inside the valve body, the valve cavity 1213 comprises a first accommodating space 12131 and a second accommodating space 12132, a partition plate 1214 is arranged between the first accommodating space 12131 and the second accommodating space 12132, the first accommodating space 12131 accommodates a first spring 1215, the second accommodating space 12132 accommodates a second spring 1216, one end of the first spring 1215 is clamped on one side of the valve cover 1211, and the second end of the first spring 1215 is clamped on the other side of the valve cover 1211. Connected to the first accommodating space 12131, one end of the second spring 1216 is clamped on the other side of the valve cover 1211, and the second end of the second spring 1216 is clamped in the second accommodating space 12132; the second spring 1216 is sleeved on the outside of the first spring 1215, and the elastic force of the first spring 1215 and the second spring 1216 makes the valve cover 1211 cover the valve port 12121 of the valve body 1212, when receiving external force, the first spring 1215 and the second spring 1216 are compressed, the valve cover 1211 is opened, and the inert gas enters and exits the valve body 1212 through the valve port 12121.

[0065] Specifically, the partition 1214 is an annular partition arranged around the axis of the first spring 1215 and the second spring 1216 .

[0066] In the embodiment of the present application, when the valve cover 1211 receives external pressure, the first spring 1215 and the second spring 1216 are compressed, the valve cover 1211 is opened, and the inert gas can enter the valve body 1212 or be discharged from the valve body 1212 through the valve port 12121. When the external pressure disappears, the elastic force of the first spring 1215 and the second spring 1216 causes the valve cover 1211 to cover the valve port 12121 of the valve body 1212, thereby preventing the inert gas from entering the valve body 1212 or being discharged from the valve body 1212 through the valve port 12121.

[0067] In the embodiment of the present application, a partition 1214 is provided to divide the valve cavity 1213 into a first accommodating space 12131 and a second accommodating space 12132, so that one end of the first spring 1215 is clamped in the first accommodating space 12131, and one end of the second spring 1216 is clamped in the second accommodating space 12132, thereby ensuring that the double spring structure can be quickly installed in the valve cavity 1213. The advantage of such a setting is that the partition 1214 is used to separate the first spring 1215 and the second spring 1216, thereby avoiding the first spring 1215 and the second spring 1216 from overlapping each other, resulting in the problem of excessive resistance of the first spring 1215 and the second spring 1216 when the inflation and deflation valve 121 is opened, ensuring that the inflation and deflation valve 121 can be opened normally, the opening amplitude of the inflation and deflation valve 121 reaches the normal range, the inert gas can pass smoothly, and the user experience is good. In addition, the elastic force provided by the first spring 1215 and the second spring 1216 of the present application can further ensure that the valve cover 1211 tightly covers the valve port 12121 of the valve body 1212, thereby preventing the loss of inert gas from affecting the resilience of the airbag 12. The insole 1 of the present application embodiment can prevent the loss of inert gas even in high-intensity sports such as marathons, thereby further achieving the provision of resilience, protecting the sole of the foot, and improving running performance.

[0068] In the application of the embodiment of the present application, if the valve cover 1211 needs to be opened to allow the inert gas to enter the valve body 1212 through the valve port 12121, the inflator 2 presses the valve cover 1211, and the pressing bracket 21 of the inflator 2 presses the valve cover 1211, the first spring 1215 and the second spring 1216 into the airbag 12, and the airbag 12 is inflated through the inflator nozzle 22, so that the inert gas enters the valve body 1212 and then enters the airbag 12. After the inflation is completed, the inflator 2 only needs to stop applying the pressing force to the valve cover 1211, and the valve cover 1211 can, under the rebound force of the first spring 1215 and the second spring 1216, abut the cover body 12111 against the valve port 12121, maintain the closedness of the airbag 12, and prevent the loss of inert gas.

[0069] The method for inflating the airbag 12 in the embodiment of the present application is simple and convenient, and the airbag 12 can be inflated through independent operation by the user.

[0070] Furthermore, the airbag 12 of the embodiment of the present application is replaceable, and the user can also replace the airbag 12 for the insole. The user can further reduce the use cost of the insole 1 by purchasing the airbag 12 separately.

[0071] Specifically, see Figure 3The valve cover 1211 also includes a cover body 12111 and a telescopic rod 12112. The cover body 12111 and the telescopic rod 12112 move synchronously. A spring clamp 12113 corresponding to the upper and lower parts of the partition is arranged on the cover body 12111. The spring clamp 12113 is used to clamp the first ends of the first spring 1215 and the second spring 1216 respectively. The spring clamp 12113 receives the elastic force of the first spring 1215 and the second spring 1216 to push the cover body 12111 to the valve port 12121.

[0072] The embodiment of the present application transmits the rebound force of the first spring 1215 and the second spring 1216 to the cover body 12111 through the cover body 12111, the telescopic rod 12112 and the spring seat 12113, so that the valve cover 1211 and the valve port 12121 are better sealed, maintaining the sealing of the airbag 12 and preventing the loss of inert gas.

[0073] In some specific implementations of the embodiments of this application, see Figure 4 An elastic rubber sealing cover 1217 is provided on the outer periphery of the valve cover 1211 . The radius of the sealing cover 1217 is larger than the radius of the valve opening 12121 . Under the action of the rebound force, the sealing cover 1217 is pushed to seal and block the valve opening 12121 .

[0074] Specifically, the sealing cover 1217 is a silicone sealing cover. The sealing cover 1217 is arranged around the valve cover 1211 and has a radius greater than the radius of the valve port 12121, so as to prevent the valve cover 1211 from being pushed against the valve port 12121, resulting in a gap between the valve cover 1211 and the valve port 12121, thereby preventing the loss of inert gas. In high-intensity sports such as marathons, even if the airbag is subjected to great pressure, or even subjected to great pressure for a long time, the embodiment of the present application can prevent the loss of inert gas.

[0075] In the specific implementation of the first embodiment of the present application, see Figure 5 The gas charging and discharging valve 121 further includes:

[0076] The sealant layer 1218 covers the upper surface of the valve cover 1211 , and the valve cover 1211 seals the valve port of the valve body through the sealant layer 1218 .

[0077] Specifically, the sealant layer 1218 is an adhesive tape, which is attached to the upper surface of the valve cover 1211. If the inflation and deflation valve 121 is opened, the adhesive tape can be torn off, and the sealant layer 1218 is replaceable, thereby further avoiding the loss of the inert gas.

[0078] In the specific implementation of the first embodiment of the present application, see Figure 6 , the insole 1 also includes:

[0079] The pressure sensor 14 is arranged inside or on the outer surface of the airbag 12, corresponding to the position of the forefoot and the heel. The pressure sensor 14 is used to sense the pressure of the forefoot and the heel, and send the sensed pressure value to the controller 3, so that the controller 3 determines whether to increase or decrease the inert gas in the airbag according to the pressure value.

[0080] Specifically, the pressure sensor 14 senses the pressure of the forefoot and the rear foot, and sends the sensed pressure value to the controller 3. The controller 3 can be set on the insole 1 or on the shoe, or even on other portable devices of the user. The pressure sensor 14 sends the pressure value to the controller 3 through the communication interface, and the sending method can be wired or wireless.

[0081] For example, the pressure sensor 14 is connected to a USB cable via a USB port to send the pressure value sensed during daily use of the insole to the controller. For another example, the pressure sensor 14 sends the pressure value sensed during daily use of the insole to the controller via a Bluetooth interface.

[0082] The present application does not limit the manner in which the pressure sensor 14 transmits pressure values. The pressure values ​​sensed by the pressure sensor 14 include at least one of the following: a pressure value during running, a pressure value during walking, a pressure value during stationary state, and a pressure value when not in use.

[0083] Specifically, the pressure value during running includes the pressure values ​​during running at different paces and at different times.

[0084] The present application can determine the pressure conditions of the insole 1 in different usage scenarios by sensing the pressure values ​​of different usage states, and adjust the inert gas in the air cushion 12 in the insole 1 according to different usage scenarios, so that the insole 1 can better meet the needs of rebound force in different usage scenarios and achieve better sports effects.

[0085] In the specific implementation of the first embodiment of the present application, see Figure 7 , the insole 1 also includes:

[0086] The distance sensor 15 is arranged inside or on the outer surface of the airbag 12, corresponding to the position of the forefoot and the heel. The distance sensor 15 is used to sense whether there is a gap between the forefoot, the rear foot and / or the arch and the airbag, so that the controller 3 determines whether to increase or decrease the inert gas in the airbag according to the gap.

[0087] Specifically, the distance sensor 15 senses whether there is a gap between the forefoot, the rear foot and / or the arch and the airbag, and sends the sensed gap to the controller 3 .

[0088] The distance sensor 15 sends the pressure value to the controller 3 via the communication interface, and the sending method can be wired or wireless.

[0089] For example, the distance sensor 15 is connected to a USB cable via a USB port, and sends the gap sensed during daily use of the insole to the controller. For another example, the distance sensor 15 sends the gap sensed during daily use of the insole to the controller via a Bluetooth interface.

[0090] The present application does not limit the manner in which the distance sensor 15 transmits the gap. The gap sensed by the distance sensor 15 includes at least one of the following: a gap during running, a gap during walking, a gap during stationary state, and a gap during non-use.

[0091] Specifically, the intervals during running include intervals during running at different paces and different times.

[0092] The present application can determine the gap conditions of the insole 1 in different usage scenarios by sensing the gaps in different usage states, and adjust the inert gas in the air cushion 12 in the insole 1 according to different usage scenarios, so that the insole 1 can better meet the needs of different usage scenarios for rebound force and achieve better sports effects.

[0093] Furthermore, since the airbag 12 arranged at the arch position is to reduce the impact of flat feet on daily body shape and muscle strength, the embodiment of the present application adjusts the height of the airbag 12 according to the improvement state of flat feet by adjusting the inert gas in the airbag 12 at the arch position, thereby improving the fit between the insole and the arch.

[0094] The embodiment of the present application can make the insole 1 adapt to users with different flat feet by adjusting the inert gas in the airbag 12 at the arch position, thereby greatly improving the user experience.

[0095] In a specific implementation of the first embodiment of the present application, the controller 3 calculates according to the pressure value and the gap, determines the opening and deflation time or the opening and inflation time of the inflation and deflation valve of the airbag 12, and controls the inflation and deflation valve to open or close.

[0096] Specifically, the controller 3 in the embodiment of the present application can calculate the opening and deflation time or the opening and inflation time of the inflation and deflation valve of the airbag 12 according to a preset model and using artificial intelligence.

[0097] For example, the preset model is trained using the user's daily running data, and the training samples include: pressure values ​​in different use states and gaps in different use states, and at least one of the user's weight, height, gender, exercise habits, etc. The trained model calculates the opening and deflation time or opening and inflation time of the inflation and deflation valve of the airbag 12 according to the input pressure value and gap, so that the inert gas in the airbag 12 better meets the needs of the user and improves the user experience.

[0098] For example, the inert gas filled for a 50 kg female and a 75 kg male may be different. The embodiment of the present application can fill the inert gas according to the user's own situation to meet the needs of different users.

[0099] In the embodiment of the present application, the controller 3 is used to control the opening and deflation time or the opening and inflation time of the inflation and deflation valve of the airbag 12 , and the controller 3 may also be used to control the opening or closing of the inflation and deflation valve 121 .

[0100] Specifically, when there is too much inert gas in the airbag, the inert gas is discharged from the airbag by opening the inflation and deflation valve 121 of the airbag 12, so that the inert gas in the airbag 12 can be adjusted during the use of the insole 1. The airbag adjustment can be achieved without stopping the movement, meeting the requirement of movement continuity.

[0101] In the specific implementation of the first embodiment of the present application, see Figure 8 In order to facilitate ventilation and perspiration, the insole 1 also includes a plurality of ventilation holes 16 for ventilation and perspiration.

[0102] The embodiment of the present application further provides an airbag 12, and the airbag 12 includes the above-mentioned inflation and deflation valve 121, which will not be described in detail in this application.

[0103] The above implementation methods are only used to illustrate the embodiments of the present application, and are not limitations on the embodiments of the present application. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the embodiments of the present application.
