Background technique

At present, in the footwear products, the air cushion has a wide range of applications due to its buffer function. The usual air cushion is a pneumatic pressurized air cushion to provide better energy feedback. The energy feedback of the air cushion increases due to the increased motion impact, when the amount of motion impact is large. The energy feedback will be too large to increase the discomfort of the leg and even cause injury; when the amount of exercise impact is small, the rebound provided will be insufficient, which will affect the performance of the exercise.

detailed description

1 to 8, the present invention is an airbag ventilation structure and an insole and a shoe. The airbag ventilation structure has a first airbag 1 and a second airbag 2, and the pressure relief valve 3, the differential pressure valve 4, and the gas damper 5 may be disposed between the first airbag 1 and the second airbag 2. This achieves different motion states and produces corresponding energy feedback. The pressure relief valve 3, the differential pressure valve 4 and the gas damper 5 are bonded or integrally formed between the first airbag 1 and the second airbag 2, so that the cost is low and the production is convenient.

Referring specifically to FIG. 4, the pressure relief valve 3 includes a tubular body 61, a valve 62 that is contracted in the tubular body 61 to form a stepped shape, and a reciprocable piston 63. A spring 64 is disposed between the piston 63 and the tubular body 61. At the reset piston 63, the piston 63 blocks the valve 62 when the spring 64 is in a natural state. The piston 63 is on the side close to the second airbag 2, and the valve 62 is on the side close to the first airbag 1, and the pressure relief valve 3 is similar to the one-way valve, so that the air pressure generated by the first airbag 1 can quickly push the piston 63 to move. The pressure relief valve belongs to the prior art, but the existing pressure relief valve is mostly a metal component, and the structure is complicated, and the pressure relief valve needs to be adapted in different application fields. The pressure relief valve 3 in this embodiment has a simple structure. Easy to make.

Referring specifically to FIG. 5, the differential pressure valve 4 includes a tubular body 61, a valve 62 that is contracted in the tubular body 61 to form a stepped shape, and a reciprocable piston 63. A spring 64 is disposed between the piston 63 and the tubular body 61. In the reset piston 63, there is a gap between the piston 63 and the valve 62 when the spring 64 is in a natural state. The piston 63 is on the side close to the first airbag 1, and the valve 62 is on the side close to the second airbag 2, so that the air pressure generated by the first airbag 1 can quickly push the piston 63 to move.

The gas damper 5 has two principles, one is to use a gas to flow through a narrow long tube to slow down the flow rate, and the other is to use gas recoil to counteract the impact. Referring specifically to Fig. 6, the gas damper 5 includes a tubular body 61. The inner diameter of a length of the tubular body 61 is contracted to form a narrow flow passage. The inner diameter of both ends of the tubular body 61 is larger than the narrow flow passage, and the narrow flow passage serves as a speed reducing member. This corresponds to the first principle. Referring specifically to Figure 6, the side wall of the gas damper 5 is provided with a plurality of curved tubes 65. When the inlet of the curved tube 65 follows the direction of the air flow and the outlet is opposite to the direction of the air flow, the gas flow is blocked, and vice versa. 7, the left end elbow 65 of the gas damper 5 blocks the flow of gas from left to right, and the right end of the elbow 65 blocks the flow of gas from right to left, respectively, and two kinds of elbows 65 having opposite inlet directions are respectively disposed, and thus The two-way choke of the gas is realized, and the elbow 65 serves as a deceleration member. However, the gas damper 5 of Fig. 5 is simple and practical.

Referring to Fig. 1, a pressure relief valve 3 and a gas damper 5 are disposed between the first airbag 1 and the second airbag 2. When the first airbag 1 is subjected to a large impact, the pressure relief valve 3 is turned on to reduce the first airbag 1 pair. The rebound of the foot is more comfortable. When the impact is small, the pressure relief valve 3 is blocked, so that the first airbag 1 retains most of the gas, providing a large amount of rebound and becoming comfortable. After the third transposed pressure relief valve 3 is additionally disposed between the first airbag 1 and the second airbag 2, the port of the pressure relief valve 3 is exchanged, and the second airbag 2 can also bring about the above effects when the second airbag 2 is impacted. . This airbag ventilation structure is mainly used in sports shoes, which can effectively protect the athlete's feet, and a good rebound also contributes to sports bouncing. Referring to Fig. 7, since the first airbag 1 is mainly subjected to an impact, the volume of the first airbag 1 is large, and it is possible to provide a plurality of second airbags 2 around the first airbag 1.

Referring to Fig. 2, a differential pressure valve 4 and a gas damper 5 are disposed between the first airbag 1 and the second airbag 2, and the rebound is reduced when the first airbag 1 is greatly impacted, and has good elasticity at the time of small impact. Of course, after the third transposed differential pressure valve 4 is additionally provided between the first airbag 1 and the second airbag 2, the above effect can also be obtained when the second airbag 2 is subjected to an impact.

Referring to Fig. 3, a pressure relief valve 3 and a differential pressure valve 4 are disposed between the first airbag 1 and the second airbag 2, and each of the pressure relief valve 3 and the differential pressure valve 4 has a respective critical pressure. The critical pressure P1 of the differential pressure valve 4 is set to be smaller than the critical pressure P2 of the pressure relief valve 3, if the first airbag 1 generates a pressure shock of P3, when P3 is between P1 and P2, the differential pressure valve 4 and the pressure relief The valve 3 is not turned on, the gas in the first air bag 1 cannot flow, and the rebound can be reduced; otherwise, under the P3 pressure, the pressure difference valve 4 is not turned on, and the pressure relief valve 3 is turned on. The first airbag 1 in the case is relatively soft.

Referring to FIG. 8, an airbag ventilation structure may include a first airbag and a plurality of second airbags, and a first pressure relief valve, a differential pressure valve or a gas damper is disposed between the first airbag and each of the second airbags. Two.

In use, the air bag ventilation structure of Figures 2 and 3 can be used in other non-shoe fields as needed.

An insole comprising a soft midsole incorporating a balloon venting structure as described in the above scheme, wherein the midsole is made of a foamed plastic or other material capable of transmitting deformation, which facilitates triggering the first bladder 1. Since the first airbag 1 is mainly subjected to an impact at the time of design, the first airbag 1 is placed at the forefoot or rear heel position of the insole.

A shoe that uses an insole as described above.

A shoe comprising a soft midsole, the direct midsole is embedded with the airbag ventilation structure as described in the above scheme, and the upper part of the midsole is made of foamed plastic or other material capable of transmitting deformation, so that the first airbag 1 is easily triggered. Since the first airbag 1 is mainly subjected to an impact at the time of design, the first airbag 1 is usually placed at the midsole position.

When the airbag ventilation structure is installed, the pressure relief valve 3, the differential pressure valve 4 and the gas damper 5 can be appropriately connected to the first airbag 1 or the second airbag 2 through a hose, such that the pressure relief valve 3 and the differential pressure valve 4 and the position of the gas damper 5 can be arranged more flexibly.

Of course, the design creation is not limited to the above embodiment, and a combination of different features of the above embodiments can also achieve good results. Equivalent variations or substitutions may be made by those skilled in the art without departing from the spirit of the invention, and such equivalents and modifications are intended to be included within the scope of the appended claims.
