Description

Technical Field

[0001] The invention relates to the technical field of running shoes, in particular to a pair of adaptive damping adjustable professional running shoes. Background Art

[0002] As living standards continue to improve, people have become keen on fitness, and aerobic exercise is very popular. Among them, jogging has very low requirements for the venue and equipment required, making jogging the most chosen sport. The adaptive damping adjustment professional running shoes are a kind of sports equipment that integrates advanced technology. It can adjust the damping in real time according to the runner's movement state and ground conditions, provide sufficient support and rebound force when running, help runners move forward more easily, improve running efficiency, and help improve sports performance. In addition, the adaptive damping adjustment can make the running shoes better adapt to different running scenarios, such as hard ground, soft ground, etc., provide a more comfortable landing feeling for the feet, and reduce the fatigue caused by long-term running.

[0003] At the same time, adaptive damping adjustment professional running shoes use advanced sensors and control systems, which can sense the runner's movement parameters in real time, such as speed, cadence, stride strength, etc., as well as external environmental factors such as ground hardness, and automatically adjust the damping without the runner's manual operation. However, the sensor and adjustment system may not react fast enough due to the small pressure sensing surface, resulting in the running shoes being unable to adjust the damping in time according to the movement state and ground changes. For example, when suddenly transitioning from hard ground to soft ground, the running shoes may not be able to increase the damping quickly, making the runner feel insufficiently supported, affecting the running experience, and may even increase the risk of injury.

[0004] In the patent document with the publication number CN110122970B, a fitness running shoe is disclosed, including a sole and an upper. When a person walks, the elastic support component can play a supporting role, and the user's wearing comfort is good. At the same time, when the human foot steps on the upper sole, a pair of support bodies of the elastic support part will be compressed and deformed. The deformed pair of support bodies can absorb and reduce the impact on the foot when landing, thereby protecting the foot.

[0005] When the above device is in use, it uses an elastic support component to support the shoe. Since the force used by the human body and the properties of the ground are different when running, the elastic support component is subjected to different pressures. Due to the properties of its own material, it is unable to provide relative cushioning force for athletes according to different scenarios, and thus the protection of the athlete's feet is poor.

[0006] Therefore, the present application proposes a professional running shoe with adaptive damping adjustment. Summary of the invention

The working piston slides down to different degrees according to the different forces transmitted during running, and then adaptively provides appropriate support force, thereby improving the running experience and reducing the occurrence of foot injuries to users.

DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] like Figure 1 As shown, the adaptive damping adjustment type professional running shoe proposed by the present invention comprises a first shoe layer 1, an airbag cushion assembly 2 is installed at the bottom of the first shoe layer 1, a second shoe layer 3 is installed on the side of the airbag cushion assembly 2 away from the first shoe layer 1, a plurality of buffer airbag assemblies 5 are fixedly installed at the bottom of the second shoe layer 3, and a sole 4 is fixedly installed on the side of the plurality of buffer airbag assemblies 5 away from the second shoe layer 3;

[0033] The first shoe layer 1 includes a rear sole positioning pad 101, a middle sole pad 103 is fixedly installed on one side of the rear sole positioning pad 101, and a forefoot positioning pad 102 is fixedly installed on the side of the middle sole pad 103 away from the rear sole positioning pad 101;

[0034] A first damping adjustment component 6 is installed between the second shoe layer 3 and the sole 4, just below the rear sole positioning pad 101; a second damping adjustment component 7 is installed between the second shoe layer 3 and the sole 4, just below the forefoot positioning pad 102. The first damping adjustment component 6 and the second damping adjustment component 7 have the same structure. Sensors are provided inside the first damping adjustment component 6 and the second damping adjustment component 7 for recording data such as the user's running speed and transmitted pressure. When the user usually runs, the force points are at the front and rear ends of the foot, that is, the positions of the rear sole positioning pad 101 and the forefoot positioning pad 102. When the user conducts pressure to the first shoe layer 1 while running, the pressure data and speed of the front end of the foot are collected by the first damping adjustment component 6, and the front end of the foot is better supported due to the adaptive vibration reduction of the second damping adjustment component 7, while the pressure at the rear end of the foot is better supported due to the adaptive vibration reduction of the first damping adjustment component 6, so that both force ends of the foot are protected, thereby improving the comfort and safety of the user's running.

[0035] The airbag cushion assembly 2 includes two groups of airbag blocks 202, one group of airbag blocks 202 is fixedly installed at the bottom of the rear sole positioning pad 101, and the other group of airbag blocks 202 is fixedly installed at the bottom of the forefoot positioning pad 102, a second conduction tube 205 is fixedly installed between the Y-axis airbag blocks 202, a first conduction tube 204 is fixedly installed between the X-axis airbag blocks 202, a second conduction tube 205 is fixedly installed between the Y-axis airbag blocks 202, and a first conduction tube 204 is fixedly installed between the X-axis airbag blocks 202, a hollow guide block 201 is fixedly installed at the bottom of the middle sole pad 103, a main transmission tube 203 is fixedly installed between the hollow guide block 201 and the second conduction tube 205, two groups of folding blocks 207 are fixedly installed on one side of the hollow guide block 201 toward the middle sole pad 103 through a lateral push block 206, and the two groups of folding blocks 207 form a V shape, such as Figure 1 - Figure 2 As shown, in the running state, the force is usually exerted at the forefoot positioning pad 102 and the rear foot positioning pad 101, and the middle part of the foot is obviously higher than the front and rear ends of the foot, so the middle part of the foot usually receives less support, such as Figure 4 When the front and rear ends of the user's foot exert force, the airbag ball 202 is squeezed, and the airbag ball 202 collects air to the main transmission tube 203 through the first transmission tube 204 and the second transmission tube 205, and then the main transmission tube 203 conducts the air to the sealed hollow guide block 201. The V-shaped tip of the hollow guide block 201 faces the middle sole pad 103. After receiving the air, the hollow guide block 201 passes through 207 toward the middle sole pad 103 and squeezes it, so that the middle of the foot of the user is better supported when running, and the pressure on the vibration-absorbing mechanism at the rear sole positioning pad 101 and the forefoot positioning pad 102 is reduced, thereby increasing the life of the running shoes.

[0036] like Figure 1 and Figure 3 As shown, the cushioning airbag assembly 5 includes an external airbag block 501 fixedly installed between the second shoe layer 3 and the sole 4, a telescopic airbag tube 503 is fixedly installed inside the external airbag block 501, a pushing block 502 is fixedly installed outside the telescopic airbag tube 503, and the pushing block 502 is fixedly installed on the inner wall of the external airbag block 501 at a side away from the telescopic airbag tube 503, as shown in FIG. Figure 1 and Figure 8 The external airbag block 501 is located between the second shoe layer 3 and the sole 4. The second shoe layer 3 transmits the pressure to the buffer airbag assembly 5. Under the pressure state that does not require a large load, the buffer airbag assembly 5 can be used to cushion the running process of the running shoes, reducing the loss of the first damping adjustment assembly 6. The external airbag block 501 is subjected to the pressure of the second shoe layer 3 and deforms downward together with the internal telescopic airbag tube 503. The telescopic airbag tube 503 is deformed outward under pressure, causing the pushing block 502 to increase the supporting effect on the surrounding side of the external airbag block 501, so that it is supported during the cushioning process and its own wear is reduced.

[0037] In this embodiment, the second shoe layer 3 includes an arc-shaped conduction block 301, the first damping adjustment component 6 includes an adaptive load-bearing block 602 fixedly installed at the bottom of the arc-shaped conduction block 301, a working piston 603 is rotatably installed at the bottom of the adaptive load-bearing block 602, an air shock-absorbing component 601 is fixedly installed on the top of the sole 4, a limited position slide 609 is fixedly installed inside the air shock-absorbing component 601, and a cleaning piston block 608 is slidably installed inside the limited position slide 609, such as Figure 5 - Figure 7 First, the damper is filled with silicone oil, which has good chemical stability and high and low temperature resistance. It can maintain relatively stable performance in a wide temperature range. Therefore, due to the stability and adjustability of silicone oil, it can provide stable and appropriate damping force for running shoes in different sports states and environments. For example, when running in cold weather, silicone oil will not increase viscosity significantly like some other liquids, and it can still ensure the normal operation of the damper and provide good cushioning and support for runners.

[0038] The viscosity range of silicone oil is wide. Since a sensor is provided in the load-bearing block 602, the staff can professionally repair the running shoes according to the data of the sensor, and can select silicone oils of different viscosities according to the needs to meet the requirements of the running shoe damper for different damping effects. At the same time, the silicone oil has good lubricity, which can reduce the wear of the internal parts of the damper and extend the service life of the damper.

[0039] When the adaptive load-bearing block 602 is subjected to the pressure transmitted by the arc-shaped conduction block 301, the adaptive load-bearing block 602 drives the working piston 603 to perform piston movement in the air shock-absorbing assembly 601, which will cause the silicone oil to flow between the chambers on both sides of the cleaning piston block 608. At this time, the working piston 603 will also move toward the bottom of the air shock-absorbing assembly 601 with the transmission of the silicone oil, that is, the silicone oil in the chamber on one side is squeezed and quickly flows to the chamber on the other side through the piston hole on the floating piston 610, and the chamber on the other side is between the floating piston 610 and the air shock-absorbing assembly 601. As the silicone oil at the bottom of the air shock-absorbing assembly 601 increases, the resistance of the floating piston 610 to move downward increases, which will give the floating piston 610 a reaction force, causing the silicone oil to reset and complete a vibration reduction action. In addition, during the flow of the silicone oil, severe friction and viscous resistance will be generated between its molecules and between the silicone oil and the working piston 603 and the air shock-absorbing assembly 601. Especially when passing through the narrow passage of the piston hole of the floating piston 610, a huge throttling damping will be generated, and the combined force of these effects forms a damping force, the direction of which is opposite to the movement direction of the working piston 603, thereby hindering the movement of the working piston 603;

[0040] Due to the damping force, the movement speed of the working piston 603 is gradually reduced. In this process, the pressure transmitted by the user when running is converted into the internal energy of the silicone oil molecules and dissipated in the form of heat energy, thereby achieving the purpose of damping energy consumption and reducing vibration. The working piston 603 slides down to different degrees according to the different forces transmitted during running, thereby adaptively providing appropriate support force, improving the running experience, and reducing the occurrence of foot injuries of users.

[0041] A thread 612 is provided on one side of the working piston 603 located inside the air shock absorber assembly 601. A sliding push block 607 is fixedly installed on the inner wall of the air shock absorber assembly 601. A positioning rod 606 is fixedly installed on one side of the sliding push block 607. The positioning rod 606 is slidably installed on the outer side of the thread 612. Figure 6 - Figure 7 As the working piston 603 is subjected to the pressure of the foot and moves downward along the air shock absorber assembly 601, the working piston 603 generates pressure between the thread 612 and the positioning rod 606 due to the limitation of the positioning rod 606. Since the inner wall shape of the thread 612 is arc-shaped, the working piston 603 rotates along the connection between the piston rod 604 and the adaption load-bearing block 602 according to the pressure conduction of the thread 612. At this time, the working piston 603 drives the cleaning piston block 608 to rotate together. Since there is a scraper at the bottom of the cleaning piston block 608, the cleaning piston block 608 stirs the silicone oil in transmission, thereby preventing the silicone oil from being too solidified and unable to be transmitted normally, thereby extending the service life of the damping.

[0042] A floating piston 610 is slidably mounted inside the air damping assembly 601, a spring 611 is arranged at the bottom of the floating piston 610, a piston rod 604 is rotatably mounted on the outside of the working piston 603, the piston rod 604 is slidably mounted on the outside of the air damping assembly 601, and a sealing airbag block 605 is installed on the top of the air damping assembly 601. Figure 6 As the working piston 603 moves downward, the piston rod 604 also moves downward along the air shock absorber assembly 601 synchronously, so that the working piston 603 and the interior of the air shock absorber assembly 601 are always wrapped by the piston rod 604, preventing the entry of external gas and causing problems with the air storage of the air shock absorber assembly 601, thereby extending the service life of the damping, and the sealing airbag block 605 forms a seal between the working piston 603 and the air shock absorber assembly 601 to prevent the leakage of silicone oil;

[0043] When the external force disappears, under the action of the cushioning airbag assembly 5, the spring 611 and the damping's own resilience, the working piston 603 will gradually return to the initial equilibrium position, and the silicone oil will also be redistributed in the damper to prepare for the next external force.
