A cushion layer is adhesively bonded to the lower surface of the shock-absorbing layer.

[0003] The above insole has a complex structure. Moreover, if the reset spring is compressed and extended for a long time, the elastic force value of the reset spring will decrease, affecting the buffer shock-absorbing effect of the insole and having a short service life. When the reset spring and the elastic airbag are in use fatigue, the buffer component cannot be replaced, resulting in waste of resources. Summary of the Invention

Specific embodiments

[0024] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the embodiments does not limit the present utility model.

[0025] Embodiment 1

[0026] As Figure 1-5 shown, a buffer and shock-absorbing insole includes a bottom layer 1, a buffer layer 2 and a surface layer 3. The upper end surface of the buffer layer 2 abuts against the lower end surface of the surface layer 3, and the lower end surface of the buffer layer 2 abuts against the upper end surface of the bottom layer 1. The four peripheral edges of the bottom layer 1 extend upward to form a limiting plate 4. The bottom layer 1 and the limiting plate 4 enclose an accommodating groove 5. The buffer layer 2 and the surface layer 3 are both placed in the accommodating groove 5. The limiting plate 4 is provided with a plurality of spaced clamping grooves 41. The edge of the surface layer 3 extends into the corresponding clamping grooves 41 with clamping blocks 31. The clamping blocks 31 are clamped with the corresponding clamping grooves 41.

[0027] A buffer and shock-absorbing insole of the utility model has a simple structure, strong practicability, is convenient for replacing the buffer layer 2, and saves resources. At the same time, after the user wears the shoes with this insole, during walking, the buffer layer 2 relieves the walking pressure on the user's feet, plays a role of buffering and shock absorption, protects the feet from being damaged, and improves the comfort of the soles. At the same time, the limiting plate 4 is arranged around the four peripheral edges of the bottom layer 1 to fit the shoe shape, so that the longitudinal section of the insole is U-shaped, which has a balancing effect. According to the ergonomic design, the insole fits the foot more closely, avoiding the insole from loosening and discomfort. During assembly, the surface layer 3 and the buffer layer 2 are placed in the accommodating groove 5 from top to bottom. The clamping block 31 of the surface layer 3 is clamped with the corresponding clamping groove 41. The mutual cooperation of the clamping block 31 and the clamping groove 41 makes the surface layer 3 and the buffer layer 2 not easily separated from the accommodating groove 5 during use. Correspondingly, when the buffer layer 2 needs to be replaced, only the clamping block 31 needs to be disengaged from the corresponding clamping groove 41, the surface layer 3 is removed, and then the new buffer layer 2 is used to replace the old buffer layer 2. The operation is simple, convenient for timely replacing the buffer layer 2, time-saving and labor-saving, and improves the wearing experience.

[0028] In this embodiment, a plurality of the clamping grooves 41 are respectively opened at the front end, the rear end and both ends of the middle part of the limiting plate 4. Correspondingly, a plurality of the clamping blocks 31 are arranged at the front end, the rear end and both ends of the middle part of the surface layer 3. The clamping blocks 31 are clamped with the corresponding clamping grooves 41, so that the four sides of the surface layer 3 are firmly connected to the limiting plate 4, avoiding the surface layer 3 from being easily displaced during the use of the insole, and at the same time preventing the surface layer 3 and the buffer layer 2 from separating from the accommodating groove 5, and improving the wearing experience.

[0029] Furthermore, the buffer layer 2 includes a reinforcing member 21 located in the middle of the buffer layer. Buffer members 22 are arranged at both the front end and the rear end of the reinforcing member 21. The reinforcing member 21 is a reinforcing member 21 with a convex surface. In this embodiment, the position of the reinforcing member 21 corresponds to the arch of the foot. The convex-shaped reinforcing member 21 is used to increase the height of the middle part of the insole and also to support the arch, making people walk more comfortably. Preferably, the elasticity of the reinforcing member 21 is smaller than that of the buffer member 11, which can play a good supporting role for the arch.

[0030] Further, each of the buffer members 22 includes a bearing plate 221. A plurality of shock-absorbing blocks 223 are arranged at intervals and protrude upward from the bearing plate 221. The shock-absorbing blocks 223 are made of a flexible material. In this embodiment, the shock-absorbing blocks 223 are made of rubber material, which has excellent resilience and good wear resistance. It can generate large deformation under a very small external force and can return to its original state after the external force is removed. Specifically, during the walking process, the front and rear soles of the foot will apply pressure to the two buffer members 22 respectively. At this time, the pressure will be transmitted to the shock-absorbing blocks 223. The shock-absorbing blocks 223 are deformed by the force, playing a buffering role during the process of stepping on the sole, reducing the pressure on the foot and improving the wearing experience.

[0031] Further, a first accommodating cavity 224 is provided in the shock-absorbing block 223, and a gas is provided in the first accommodating cavity 224, which can reduce the weight of the insole and make it easy to wear.

[0032] Further, a plurality of the shock-absorbing blocks 223 are arranged to form multiple rows of shock-absorbing block groups. The multiple rows of shock-absorbing block groups are arranged in sequence along the length direction of the bearing plate 221. Each shock-absorbing block group includes a plurality of shock-absorbing blocks 233 arranged in sequence along the width direction of the bearing plate 221, which is convenient for the shock-absorbing blocks 223 to play a good buffering and shock-absorbing role for the user during the walking process.

[0033] Further, a plurality of second accommodating cavities 222 are provided in the bearing plate 221 at intervals along the length direction of the bearing plate 221. The second accommodating cavities 222 are located at the lower ends of the corresponding rows of shock-absorbing block groups. The number of the second accommodating cavities 222 is the same as the number of the shock-absorbing block groups. The first accommodating cavities 224 of the shock-absorbing blocks 223 in the same shock-absorbing block group communicate with the corresponding second accommodating cavities 222. Specifically, during the walking process, the front and rear soles of the foot will apply pressure to the two shock-absorbing members respectively. At this time, the pressure will be transmitted to the plurality of shock-absorbing blocks 223, squeezing the shock-absorbing blocks 223. During the process, the gas in the first accommodating cavities 224 of the shock-absorbing blocks 223 in the same shock-absorbing block group flows through the second accommodating cavities 222 and circulates between the first accommodating cavities 224 of the same row for buffering and unloading force. On the one hand, it reduces the risk of the shock-absorbing blocks 223 being damaged due to excessive force, and on the other hand, it can play a buffering role during the process of stepping on the sole, reducing the vibration of the human foot during walking. And during the process of gas flow, fluctuations will occur on the surface of the shock-absorbing blocks 223, and this kind of fluctuation can also play a certain massage role for the foot. At the same time, since the buffering and deformation are completed by the outflow of gas, there will be no counter-vibration.

[0034] Further, the card slot 41 communicates with the bottom layer 1. The length of the card slot 41 from top to bottom is greater than the thickness of the buffer layer 2, that is, the bottom of the card slot 41 communicates with the bottom layer 1. A first connecting member 6 is provided at the upper end of the bottom layer 1, and a second connecting member 7 is provided at the lower end of the surface layer 3. When the buffer layer 2 is removed from the insole, the surface layer 3 is disposed on the upper end of the bottom layer 1, and the second connecting member 7 is used for detachably connecting with the first connecting member 6. The length of the card slot 41 from bottom to top is greater than the thickness of the buffer layer 2, which facilitates the engagement of the clamping block 31 with the corresponding card slot 41 when the buffer layer 2 is removed from the insole. Specifically, when the user does not need to add the buffer layer 2 to the insole, the clamping block 31 is only required to be disengaged from the corresponding card slot 41, the surface layer 3 is removed, then the buffer layer 2 is taken, the first connecting member 6 of the surface layer 3 is connected to the second connecting member 7, so that the surface layer 3 and the bottom layer 1 are firmly connected, and the clamping block 31 is engaged with the corresponding card slot 41, so that the surface layer 3 and the limiting plate 4 are firmly connected, avoiding the surface layer 3 being easily separated from the accommodating groove 5 during use and improving the wearing experience. In this embodiment, both the first connecting member 6 and the second connecting member 7 are magic tapes, and the structure is simple.

[0035] Further, an arch support 8 for matching with the arch area of the foot is protruded on the upper surface of the surface layer 3. The arch support 8 can play a good supporting role for the arch area of the user and improve the wearing experience of the user.

[0036] Further, an antibacterial layer 9 is provided at the upper end of the surface layer 3. The material of the antibacterial layer 9 is bamboo charcoal fiber. It can effectively inhibit the growth of bacteria in the insole, thereby reducing the growth of bacteria in the shoe and on the feet, and effectively ensuring the foot health of the user.

[0037] Embodiment 2

[0038] Different from Embodiment 1, a first accommodating cavity 224 is provided in the shock-absorbing block 223 in this Embodiment 2. A liquid is provided in the first accommodating cavity 224, so that the shock-absorbing block 223 can absorb part of the heat of the foot and has the function of quickly cooling down, improving the wearing experience. Preferably, the liquid is a mixture of Na2SO4·10H2O crystals and Na2SO4 solution. The melting point and freezing point of Na2SO4·10H2O are about 32.4 °C, while the normal temperature of the human body is 37 °C. When the foot contacts the shock-absorbing block 223, the crystals in the first accommodating cavity 224 absorb heat and melt, making the foot feel cool. If all the crystals in the first accommodating cavity 224 melt, when the insole is not in use, the solution releases heat and the Na2SO4·10H2O crystals precipitate out, and it can be reused, with high utilization rate and strong practicability.

[0039] Further, a plurality of second accommodating cavities 222 are provided in the bearing plate 221 at intervals along the length direction of the bearing plate 221. Each second accommodating cavity 222 is correspondingly arranged with each row of shock-absorbing blocks 223, and the first accommodating cavity 224 of each row of shock-absorbing blocks 223 communicates with the corresponding second accommodating cavity 222. Specifically, during the walking process of people, the front and rear soles of the feet will respectively apply pressure to the two shock-absorbing members. At this time, the pressure will be transmitted to a plurality of shock-absorbing blocks 223, squeezing the shock-absorbing blocks 223. During the process, the liquid in the first accommodating cavity 224 of the shock-absorbing blocks 223 in the same shock-absorbing block group flows between the first accommodating cavities 224 of the other rows in the same row through the second accommodating cavity 222 for buffering and unloading force. On the one hand, it reduces the risk of the shock-absorbing blocks 223 being damaged due to excessive force, and on the other hand, it can play a buffering role during the process of stepping on the sole of the foot, reducing the vibration of the human foot during walking. And during the flow of the liquid, fluctuations will occur on the surface of the shock-absorbing blocks 223, and this kind of fluctuation can also play a certain massage role on the feet. At the same time, since the buffering and deformation are completed by the outflow of the liquid, there will be no counter-vibration.
