Description

Technical Field

[0001] This utility model belongs to the field of sports shoe technology, specifically relating to a shock-absorbing sports running shoe. Background Technology

[0002] Running shoes are shoes designed primarily for running and other sports. They need to have good comfort, support, and durability so that people can engage in outdoor activities for extended periods. Among these, the shock absorption performance of running shoes is directly related to their comfort. Good shock absorption performance can not only provide good comfort but also reduce pressure on the joints of the lower limbs, thus playing a good protective role.

[0003] In related prior art, such as Chinese Patent No. CN221785487U, a sports shoe sole with anti-slip and shock-absorbing functions is disclosed. It includes a main body and a cushioning and shock-absorbing mechanism, with the latter located at the inner end of the main body. The main body includes a sports shoe sole body, a connecting edge, and an anti-slip block. The connecting edge is fixedly installed at the upper end of the sports shoe sole body, and the anti-slip block is fixedly installed at the lower end. The main body also includes anti-slip protrusions, anti-slip strips, anti-slip patterns, and a wear-resistant layer. The anti-slip protrusions are fixedly installed at the lower end of the sports shoe sole body, located in the middle of the anti-slip block, and the anti-slip strips are fixedly installed in the middle of the lower end of the sports shoe sole body. This sports shoe sole with anti-slip and shock-absorbing functions, by installing a shock-absorbing mechanism, facilitates improved shock absorption and cushioning effects, enhances wearer comfort during exercise, meets wearer needs, and improves practicality.

[0004] However, in actual use, sports shoes often involve local compression, bending, and twisting deformations. The movement direction of the shock absorber is limited by its stroke, and it cannot bend or twist freely. As a result, sports shoes will bring a large lateral torsional shear force to the shock absorber during use, which may lead to damage to the shock absorber. In other words, the reliability of the above-mentioned shock absorption structure is low and it is not conducive to actual use. Utility Model Content

[0005] The present invention aims to provide a shock-absorbing running shoe to solve the problem of low reliability of existing shock-absorbing structures in sports shoes mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing running shoe, comprising...

[0007] The sole comprises a bottom layer, a middle layer, and a top layer arranged sequentially from bottom to top. The middle layer has an internal cavity, and the cavity has a partition strip in the middle.

[0008] The shock-absorbing structure includes airbags, molded foam, and one-way ventilation components. Airbags are installed on both sides of the partition strip. The airbags are located in the receiving cavity. The molded foam is filled in the airbags. The airbags have multiple one-way ventilation components, and the ventilation direction of at least one one-way ventilation component on the airbag is opposite to the ventilation direction of the other one-way ventilation components.

[0009] The upper is installed on the top layer.

[0010] The principle and effects of this technical solution:

[0011] 1. The airbag design absorbs and cushions the vibrations from stepping on the sole. The one-way ventilation component allows the air pressure inside the airbag to be relieved when compressed, thus providing shock absorption and protecting the airbag. After stepping off the shoe, air can enter the airbag through the one-way ventilation component to restore its shape. At the same time, the air intake and exhaust of the airbag brings cool air into the shoe, ensuring breathability. Local bending or twisting deformation of the sole will not damage the cushioning structure.

[0012] 2. The molded foam supports the shape of the airbag, preventing significant compression and deformation of the sole thickness when the wearer steps on it, even when the internal air pressure of the airbag is the same as the external pressure. This avoids safety accidents caused by large deformation, and the molded foam can also restore the airbag to its original shape after the pressure is removed due to its own elasticity.

[0013] 3. By installing the airbag in the middle layer, it provides better protection for the airbag. The addition of a partition strip strengthens the connection between the top and bottom layers. The airbag is divided into two parts, with the forefoot and heel each having their own airbag area. This ensures that the wearer can enjoy shock absorption when the foot contacts the ground in segments (when walking, the foot usually touches the ground partially before landing as a whole, specifically the forefoot first and then the heel. With a one-piece airbag, the airbag is partially compressed and gas leaks out when the forefoot contacts the ground, resulting in a decrease in shock absorption. The shock absorption effect is also weaker when the heel subsequently contacts the ground).

[0014] The present invention is further configured as follows: the one-way ventilation component includes a ventilation channel, a movable belt, a sealing plug and a magnetic component. One end of the ventilation channel is connected to the airbag, and the other end of the ventilation channel passes through the top layer and is connected to the outside. One end of the movable belt is installed on the ventilation channel, and the other end of the movable belt is magnetic. The sealing plug is fixed on the movable belt and is adapted to the ventilation channel. The magnetic component is installed on the ventilation channel.

[0015] The principle and effect of this technical solution are as follows: By setting a sealing plug, a movable band, and a magnetic absorbing element outside the ventilation channel, the magnetism of the movable band and the magnetic absorbing element can seal the ventilation channel. External air pressure is pressed against the movable band and cannot enter the ventilation channel. On the other side, when the gas is pressurized, the gas pressure can overcome the magnetism between the movable band and the magnetic absorbing element, causing the movable band to move away from the ventilation channel, thereby releasing the seal on the ventilation channel and allowing gas to flow out through the ventilation channel. This component provides one-way ventilation. When the airbag is compressed (when the wearer puts on shoes and steps on the ground), the pressure can drive the airbag to compress, making the atmospheric pressure inside the airbag greater than the external atmospheric pressure. The gas inside the airbag can flow out of the airbag through the one-way ventilation component. After the pressure is released (when the wearer puts on shoes and leaves the ground), under the effect of the restoring force of the shaping sponge and the pressure difference between the airbag and the outside air (gas loss), atmospheric gas can enter the airbag through the one-way ventilation component in the opposite direction, thereby restoring the airbag.

[0016] The present invention is further configured such that: the ventilation duct includes a ventilation area and a control area, the radial dimension of the control area is larger than the radial dimension of the ventilation area, the sealing plug is adapted to the ventilation area, the movable belt is installed in the control area, and the magnetic suction component is fixed to the side of the ventilation area close to the control area.

[0017] The principle and effect of this technical solution: By setting up a control zone with a large aperture and a ventilation zone with a small aperture, when gas enters the ventilation zone from the control zone, the movable belt can reliably seal the ventilation zone through magnetic attraction and gas thrust. When gas reaches the control zone from the ventilation zone, the movable belt can be driven to rotate in the control zone by air pressure, thereby causing the sealing plug to leave the ventilation zone and play a role in ventilation. After the air pressure disappears, the sealing plug is reset under the magnetic attraction of the movable belt.

[0018] The present invention is further configured such that: the airbag has multiple relief grooves, springs are installed in the relief grooves, protective pads are fixed at both ends of the springs respectively, and the protective pads at both ends abut against the bottom layer and the top layer respectively, and the protective pads are fixed to the airbag.

[0019] The principle and effect of this technical solution: By setting up springs and protective pads, they can play a shock-absorbing role in sync with the airbag. At the same time, the springs' own rebound force can drive the protective pads to reset, thereby pulling the airbag to recover through the protective pads, which facilitates the entry of gas into the airbag.

[0020] The present invention is further configured such that a rubber ring is fitted inside the relief groove, and the spring is located inside the rubber ring.

[0021] The principle and effect of this technical solution: The rubber ring can protect the airbag and prevent the airbag from being punctured by spring deformation, which would cause the airbag to malfunction.

[0022] The present invention is further configured such that the bottom layer is made of rubber.

[0023] The principle and effect of this technical solution: By using rubber, the bottom layer has a certain degree of flexibility while also having good wear resistance and hardness, thus providing protection for the airbag.

[0024] This invention is further characterized by having a rubber protective layer covering both the front and rear ends of the bottom layer. The principle and effect of this technical solution are as follows: by using a hard rubber protective layer, the sole can be further protected, preventing sharp objects from puncturing the bottom layer and damaging the air bladder, thereby enhancing the reliability of the shoe.

[0036] Example:

[0037] As attached Figure 1-5 As shown, this utility model discloses...

[0038] A shock-absorbing running shoe includes a sole 100, a cushioning structure, and an upper 300. The sole 100 includes a bottom layer 110, a middle layer 120, and a top layer 130 arranged sequentially from bottom to top. The middle layer 120 has a cavity 121 inside, and a partition strip 122 is located in the middle of the cavity 121. The upper 300 is installed on the top layer 130. The bottom layer 110 is made of soft rubber, which provides good contact deformation and cushioning energy absorption. The front and rear ends of the bottom surface of the bottom layer 110 are covered with rubber protective layers. The rubber protective layers are made of hard rubber, which provides good protection, slip resistance, and wear resistance.

[0039] The shock-absorbing structure includes an airbag 200, a molded sponge, and a one-way ventilation component. Airbags 200 are installed on both sides of the partition strip 122. The airbags 200 are located in the receiving cavity 121. The molded sponge is filled in the airbags 200. The airbags 200 have multiple one-way ventilation components, and the ventilation direction of at least one one-way ventilation component on the airbag 200 is opposite to the ventilation direction of the other one-way ventilation components.

[0040] The one-way ventilation assembly includes a ventilation channel 410, a movable belt 420, a sealing plug 430, and a magnetic element 440. One end of the ventilation channel 410 is connected to the airbag 200, and the other end of the ventilation channel 410 passes through the top layer 130 and is connected to the outside. The ventilation channel 410 includes a ventilation area 411 and a control area 412. The radial dimension of the control area 412 is larger than the radial dimension of the ventilation area 411. The sealing plug 430 is adapted to the ventilation area 411. The movable belt 420 is installed in the control area 412. When one-way ventilation is required, the movable belt 420 can rotate around the installation side. The other end of the movable belt 420 is magnetic. The sealing plug 430 is fixed to the movable belt 420 and is adapted to the ventilation channel 410 (e.g., Figure 5 As shown), the magnetic suction component 440 is installed on the ventilation channel 410. The magnetic suction component 440 is fixed to the side of the ventilation area 411 near the control area 412. The movable band 420 can be a rubber material with a certain deformation capability (it can deform to a certain extent and has elastic recovery capability to adapt to the deformation of the shoe and the reset after deformation), so that it can better fit and deform the control area 412. Magnetic material is mixed at the end of the movable band 420 so that the magnetic suction component 440 can magnetically attract the magnetic material. Specifically, the magnetic suction component 440 can be a magnet. The magnetic attraction force is small and is only used for one-way sealing.

[0041] The airbag 200 has multiple clearance grooves 210, and a spring 220 is installed in each clearance groove 210. Protective pads 230 are fixed to both ends of the spring 220, and the protective pads 230 abut against the bottom layer 110 and the top layer 130 respectively. The protective pads 230 are fixed to the airbag 200. A rubber ring 240 is sleeved inside the clearance groove 210, and the spring 220 is located inside the rubber ring 240. The above description is merely an embodiment of this utility model. Commonly known technical solutions or characteristics are not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
