[0046] Example 1

[0047] This embodiment provides Figures 1 to 3 The airbag insole shown includes a base pad 1 on which a plurality of inflatable airbags 2 are fixed;

[0048] The inflatable airbags 2 are connected via a connecting hose 3;

[0049] The inflatable airbag 2 is connected to the outside world through a ventilation hose 4;

[0050] The bottom cushion 1 is provided with a placement groove 11 that matches the inflatable airbag 2, the connecting hose 3 and the ventilation hose 4;

[0051] The inflatable airbag 2 is installed in the placement groove 11 through the buckle structure 7.

[0052] The airbag insole is composed of a base pad 1, an inflatable airbag 2, a connecting hose 3, and a ventilation hose 4. A placement groove 11 is provided on the base pad 1 for placing the inflatable airbag 2, the connecting hose 3, and the ventilation hose 4 to prevent the inflatable airbag 2, the connecting hose 3, and the ventilation hose 4 from moving off course during inflation and affecting the overall feel of the insole.

[0053] The inflatable airbag 2 is installed in the placement groove 11 of the base pad 1 through the snap structure 7. The connecting hose 3 is placed in the placement groove 11 and connects each inflatable airbag 2. One end of the ventilation hose 4 is connected to the inflatable airbag 2, and the other end is connected to the outside of the base pad 1. The airbag insole is finally sewn or hot-melt to the bottom end of the ordinary insole.

[0054] Furthermore, the placement groove 11 includes a forefoot groove 111 , an arch groove 112 , a heel groove 113 , and a hose groove 114 ;

[0055] The forefoot groove 111 is located at the center of the front part of the insole 1, that is, the area where the human foot contacts the insole: the forefoot area;

[0056] The arch groove 112 is located at the arch of the foot in the middle of the base pad 1, that is, where the arch of the human foot is suspended;

[0057] The heel groove 113 is located at the center of the rear portion of the base pad 1, i.e., at the heel of a human foot;

[0058] The hose groove 114 is located on the arch side of the insole 1. The arch side of the insole 1 is not the point of contact between the foot and the insole. Providing the hose groove 114 on the left side can effectively prevent the connecting hose 3 from being subjected to pressure from the insole, and also prevent the patient from having an unusual bulging feeling when wearing the insole, which would affect the correction of the arch of the foot.

[0059] A circle of tongues 115 is provided on the top of the groove wall of the placement groove 11, and the edge of the inflatable airbag 2 is plugged into the annular space formed by the tongues 115 and the placement groove 11. The elastic tongues 115 also prevent the edge of the insole from feeling strange after the inflatable airbag 2 is inflated.

[0060] Furthermore, the inflatable airbag 2 is made of two connecting surfaces 8 , and a clamping edge 24 is provided at the connection between the two connecting surfaces 8 .

[0061] Further, such as Figure 5As shown, one of the two connecting surfaces 8 is an elastic surface 81, and the other connecting surface 8 is a bottom surface 82. The inflatable airbag 2 is made of an elastic surface 81 made of a TPU film on the upper connecting surface 8, which is welded to the hard bottom surface 82 on the lower layer by heat-melting. A 3-5 mm welded edge 24 is formed on the edge of the film, and a sealed airbag cavity is formed inside the edge 24. The TPU film has excellent elasticity and wear resistance, and can withstand large external forces without causing a large amount of deformation of the body. The use of this material for one-piece molding makes the insole more stable and less prone to leakage and rupture.

[0062] The inflatable airbag 2 with a hard bottom surface 82 can only bulge upward, which in disguise reduces the degree to which the inflatable airbag 2 can bulge, greatly increases the comfort of the patient using the airbag insole, and reduces the strange feeling caused by the stability of the airbag fabric when walking.

[0063] Furthermore, the inflatable airbag 2 specifically includes three airbags, namely a forefoot airbag 21, an arch airbag 22 and a heel airbag 23, all of which are fixed in the placement groove 11 by a snap structure 7;

[0064] The forefoot airbag 21 is fixed in the forefoot groove 111 by the buckle structure 7. The shape of the forefoot airbag 21 is fully adapted to the shape of the forefoot sole. The shape of the forefoot sole of a person is similar to the shape of an animal's kidney, which is also the actual shape of the sole of a person's foot. When inflated, the insole can fully fit the forefoot sole, providing a cushioning effect on the sole and reducing the pressure on the sole caused by long-term walking.

[0065] The arch airbag 22 is fixed in the arch groove 112 by the buckle structure 7. The arch airbag 22 is shaped like a crescent moon. When inflated, it can properly support the position of the arch of the foot and fit the insole as closely as possible to reduce the strange feeling after inflating.

[0066] The heel airbag 23 is fixed in the heel groove 113 by the buckle structure 7. The heel airbag 23 is located at the center of the rear part of the base pad 1. Its shape fits the shape of the heel bone when the human foot is exerting force, that is, the disc shape.

[0067] The connecting hose 3 is snap-fitted into the hose groove 114 so that the connecting hose 3 will not bend and overflow from the base pad 1 during daily walking, thereby avoiding the pressure inside the inflatable airbag 2 caused by the possible compression caused by the connecting hose 3.

[0068] Further, such as Figure 4 As shown, the buckle structure 7 includes a convex strip 71 installed on the upper end surface of the clamping edge 24, and also includes a hook 72 matching the convex strip 71;

[0069] The hook 72 is fixedly disposed on the lower end surface of the tongue 115;

[0070] The ridge 71 can be engaged in the engaging space formed by the hook 72 and the placement groove 11. The ridge 71 matches the hook 72. Due to the particularity of the buckle structure 7, after the inflatable airbag 2 is inflated, the ridge 71 will not be pulled out of the engaging space without a reverse force. Therefore, the inflatable airbag 2 can be better clamped in the placement groove 11. When the inflatable airbag 2 needs to be replaced, the gas of the inflatable airbag 2 only needs to be released, and then the inflatable airbag 2 is pulled, and the ridge 71 can be pulled out of the engaging space under the action of external force.

[0071] The snap structure 7 allows the patient to quickly replace the inflatable airbag 2 by simply inserting the clip edge 24 of the inflatable airbag 2 that needs to be replaced and installed into the placement groove 11. Even if the inflatable airbag 2 is not perfectly placed in the placement groove 11, when a convex strip 71 is pressed into the clamping space of the hook 72, continuing to press can place the inflatable airbag 2 upright during the clamping process, so that the inflatable airbag 2 can be placed in the correct position, which is more beneficial to the patient's arch correction.

[0072] Further, such as Figure 1 and Figure 3 As shown, the right side of the heel airbag 23 is connected to the ventilation hose 4 , one end of the ventilation hose 4 is inserted into the heel airbag 23 , and the other end extends to the right outside the bottom pad 1 .

[0073] Furthermore, one end of the ventilation hose 4 is connected to the heel airbag 23 and is equipped with a first one-way air inlet device 5, and the other end extends outside the insole and is provided with a first ventilation port 41 and a second ventilation port 42, wherein the first ventilation port 41 is equipped with a second one-way air inlet device 6, and the second ventilation port 42 serves as a ventilation end;

[0074] The first one-way air inlet device 5 and the second one-way air inlet device 6 have the same air inlet direction, which is from the outside of the insole to the heel airbag 23;

[0075] The arrangement of the first one-way air inlet device 5 and the second one-way air inlet device 6 enables the ventilation hose 4 to form a structure similar to an air pump, so that the patient can use a syringe to pump air back and forth continuously under special circumstances, effectively solving the problem of arch pain caused by the patient continuing to wear the insole in an emergency. At the same time, the patient can also use the air pumping equipment normally to inflate and deflate the insole at home.

[0076] Furthermore, an air inlet pipe 51 is provided on the inner wall of the first one-way air inlet device 5. A support ring 52 is fixedly connected to the bottom end of the inner wall of the air inlet pipe 51. A return spring 53 is fixedly connected to the support ring 52. A blocking ball 54 is fixedly connected to the top of the return spring 53.

[0077] The second one-way air intake device 6 has the same structure as the first one-way air intake device 5 .

[0078] When inflating, the air pressure outside the first one-way air inlet device 5 rises, and the gas squeezes the sealing ball 54 to move inward, squeezing the return spring 53 together. The return spring 53 is tightened under the joint squeezing of the return spring 53 and the support ring 52, so that a gap is formed between the sealing ball 54 and the air inlet pipe 51, and the gas enters the inflatable airbag 2 from the air inlet pipe 51. After completing the inflation operation, the sealing ball 54 is again pressed against the air inlet pipe 51 under the action of the return spring 53, preventing the gas in the inflatable airbag 2 from overflowing; when deflation is required, the first one-way air inlet device 5 can be extended through the second air exchange port 42, and the sealing ball 54 can be manually squeezed. Since the air pressure in the inflatable airbag 2 is relatively high, the gas will automatically flow out to the outside, completing the deflation operation.

[0079] Example 2

[0080] The difference from Example 1 is that the inflatable airbag 2 adopts Figure 6 The airbag structure shown in the figure has two connecting surfaces 8, each of which is made of elastic surfaces 81 made of TPU film. The two elastic surfaces 81 are formed by double-layer hot-melt welding. A 3-5 mm thick edge 24 is formed at the edge of the film. The interior of the edge 24 forms a closed cavity for filling with gas.

[0081] The inflatable airbag 2 made of two elastic surfaces 81 has a larger gas filling volume, so that the inflatable airbag 2 can swell to a greater extent, which greatly increases the overall elasticity of the airbag insole, provides greater support for the patient's sole, and increases the shock absorption effect. It is more suitable for patients with higher requirements for sole support.

[0082] When in use: first place each inflatable airbag 2 of the airbag insole into the placement groove 11, and press the protruding strip 71 of the buckle structure 7 into the hook 72 by pressing the latch tongue 115, so that each inflatable airbag 2 is clamped on the placement groove 11 as a whole; under normal circumstances, the inflation device can be directly connected to the second air exchange port 42 for inflation. Under the action of the first one-way air intake device 5, the gas will not overflow in the opposite direction after being filled into the inflatable airbag 2. Since the second one-way air intake device 6 has the same air intake direction as the first one-way air intake device 5, the gas will not overflow from the second one-way air intake device 6 when inflating. When going out or in emergency, the patient can inflate the air through the second ventilation port 42 with a syringe carried with him. When the syringe is filled with gas for inflating, the first one-way air inlet device 5 and the second one-way air inlet device 6 will normally not affect the inflow of gas. When the syringe is used to draw air, the first one-way air inlet device 5 prevents the gas in the inflatable airbag 2 from being extracted, and the second one-way air inlet device 6 allows the gas to flow into and fill the syringe. The reciprocating operation can complete the inflation process of the syringe. After the inflation is completed, the second ventilation port 42 can be sealed with a plug.

[0083] Specifically, the connecting hose 3 and the ventilation hose 4 are inserted into the hose by cutting an opening in the TPU film, and then the hose and the TPU film are welded to form a whole. This process makes the overall structure of the insole more stable and less prone to air leakage. It also makes the three inflatable airbags 2 tightly connected, the air pressure more stable, and a better wearing experience is obtained.

[0084] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
