Technical Field
[0001] This utility model relates to the field of shock-absorbing pad technology, and more specifically, to a shock-absorbing pad that utilizes air breathing. Background Technology
[0002] In the field of fitness and exercise equipment, treadmills, as an important tool for aerobic exercise, have become indispensable fitness equipment in homes, gyms, and various sports venues due to their advantages of not being limited by weather or location. However, with people paying increasing attention to exercise and health, the shock absorption performance of treadmills has become one of the important indicators for measuring their quality. Traditional treadmill shock absorption technology, while playing a role in mitigating impact to some extent, still reveals many shortcomings in practical applications.
[0003] Traditional spring-based shock absorption systems typically use metal springs as the shock-absorbing element, absorbing the impact force generated during running through the elastic deformation of the spring. However, this shock absorption method has two main problems: first, the shock absorption effect of the spring is limited, making it difficult to completely eliminate the impact on joints such as the knees and ankles during running; second, the shock absorption performance of the spring lacks dynamic adaptability, failing to automatically adjust the shock absorption effect according to the user's weight, running speed, and running posture, resulting in significant differences in the shock absorption experience when different users use the same treadmill.
[0004] In recent years, with the continuous advancement of materials science and mechanical design technology, a novel air-breathing shock absorption technology has gradually attracted attention. This technology utilizes the compressibility and elasticity of air, and through structural design, allows air to be compressed or released under specific conditions, thereby achieving shock absorption and cushioning. However, existing air-breathing shock absorption devices are mostly used in automotive suspension systems or high-end sports shoes, with relatively few applications in treadmills, and currently suffer from problems such as slow response speed and uneven shock absorption effect. Therefore, to address the above-mentioned technical problems, this paper proposes an air-breathing shock absorption pad. Utility Model Content
[0005] The purpose of this invention is to provide an air-breathing shock-absorbing pad that can generate air pressure within the shock-absorbing rubber for cushioning and shock absorption. In addition, it is combined with multiple spring structures for cushioning, which greatly improves the cushioning effect of the shock-absorbing pad and significantly enhances the user's comfort.
[0006] This utility model is achieved through the following technical solution:
[0007] An air-breathing shock-absorbing pad includes:
[0008] The shock-absorbing pad body has a cavity inside and a through hole on the outside;
[0009] A rubber block is fixedly connected to the upper and lower sides of the cavity. A connector is fixedly connected to the outside of the rubber block. The inner side of the connector is threaded to a screw. A pressure plate is fixedly connected to the other end of the screw.
[0010] The shock-absorbing rubber has slots on both its upper and lower sides, and the pressure plate is engaged inside the slots. An air cavity is formed inside the shock-absorbing rubber, and an exhaust hole is formed on the outside of the shock-absorbing rubber, with the exhaust hole connected to the air cavity.
[0011] A sponge block is fixedly connected to the upper and lower sides inside the air cavity, and a buffer mechanism is installed inside the air cavity.
[0012] Preferably, the number of through holes is several groups arranged at equal intervals.
[0013] Preferably, the shock-absorbing rubber is made of rubber material, the air cavity is spherical, and the opening of the exhaust hole is much smaller than the inner diameter of the air cavity.
[0014] Preferably, the buffer mechanism includes a mounting cylinder, a sliding rod, a fixing plate, and a first spring. The mounting cylinder and the sliding rod are both fixedly connected to the inside of the air cavity, and there are two sets of mounting cylinders and sliding rods arranged in a centrally symmetrical manner. The end of the sliding rod is slidably connected to the inside of the mounting cylinder.
[0015] Preferably, the fixing plate is fixedly connected to the end of the slide rod, and a first spring is fixedly connected to the inner side of the mounting cylinder, and the other end of the first spring is fixedly connected to the fixing plate.
[0016] Preferably, the cavity has fixed blocks fixedly connected to its upper and lower sides, and the number of fixed blocks is several groups arranged at equal intervals. A second spring and a damper are fixedly connected between two groups of fixed blocks installed vertically and vertically, and the second spring is sleeved on the outside of the damper.
[0017] Preferably, the shock-absorbing pad body is externally fixedly connected with anti-slip strips, and the number of anti-slip strips is several groups arranged at equal intervals.
[0018] The technical solution of this utility model has at least the following beneficial effects:
[0019] This device utilizes an air-breathing shock-absorbing pad. When installed on a treadmill, the user's feet apply downward pressure to the pad's main body as they run. This pressure is transmitted through the rubber blocks and connectors, controlling the screw to push the pressure plate downwards. This causes the shock-absorbing rubber to be compressed inwards from both sides. This compression forces air out of the vent through the exhaust port. However, due to the small diameter of the exhaust port, air cannot be expelled quickly enough. Therefore, during this process, air pressure rapidly builds up inside the air chamber, creating an upward supporting force. The device effectively absorbs and cushions shocks. During the compression of the shock-absorbing rubber, the sliding rods on both sides slide symmetrically inside the mounting cylinder. At this time, the first spring is compressed by the fixed rod, which helps to buffer and reduce shocks, improving the cushioning effect. Furthermore, when the main body of the shock-absorbing pad is compressed, the second spring installed inside it also plays a certain role in cushioning. In addition, the damper helps to maintain structural stability. In summary, this device can create air pressure inside the shock-absorbing rubber for cushioning and shock absorption, and with the help of multiple sets of spring structures, it maximizes the cushioning effect of the shock-absorbing pad and greatly improves the user's comfort.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0029] Example
[0030] Please see Figure 1-7 This application discloses an air-breathing shock-absorbing pad, comprising: a shock-absorbing pad body 1, a rubber block 4, a shock-absorbing rubber 8, and a sponge block 16. The shock-absorbing pad body 1 has an internal cavity 2 and an external through hole 3. The rubber block 4 is fixedly connected to the upper and lower sides of the internal cavity 2, and a connector 5 is fixedly connected to the external side of the rubber block 4. The inner side of the connector 5 is threadedly connected to a screw 6, and the other end of the screw 6 is fixedly connected to a pressure plate 7. The shock-absorbing rubber 8 has slots 9 on both the upper and lower sides, and the pressure plate 7 is engaged inside the slots 9. An air cavity 10 is formed inside the shock-absorbing rubber 8, and an exhaust hole 11 is formed on the external side of the shock-absorbing rubber 8, and the exhaust hole 11 is connected to the air cavity 10. The sponge block 16 is fixedly connected to the upper and lower sides of the internal air cavity 10, and a buffer mechanism is installed inside the air cavity 10.
[0031] The number of through holes 3 is several groups arranged at equal intervals. The through holes 3 are set to facilitate timely replenishment of air into the air cavity 10 to form air pressure for shock absorption.
[0032] The shock-absorbing rubber 8 is made of rubber material and can have a certain buffering and shock-absorbing effect. The air cavity 10 is spherical and the opening of the exhaust hole 11 is much smaller than the inner diameter of the air cavity 10, which makes it easier to form air pressure inside the air cavity 10.
[0033] The buffer mechanism includes a mounting cylinder 12, a sliding rod 13, a fixing plate 14, and a first spring 15. The mounting cylinder 12 and the sliding rod 13 are both fixedly connected to the inside of the air cavity 10. There are two sets of mounting cylinders 12 and sliding rods 13, which are arranged in a centrally symmetrical manner. The end of the sliding rod 13 is slidably connected to the inside of the mounting cylinder 12.
[0034] The fixing plate 14 is fixedly connected to the end of the slide rod 13. The first spring 15 is fixedly connected to the inner side of the mounting cylinder 12, and the other end of the first spring 15 is fixedly connected to the fixing plate 14.
[0035] The cavity 2 is fixedly connected to the upper and lower sides with fixed blocks 17. There are several groups of fixed blocks 17 arranged at equal intervals. A second spring 18 and a damper 19 are fixedly connected between two groups of fixed blocks 17 installed at the upper and lower sides. The second spring 18 is sleeved on the outside of the damper 19. The damper 19 can ensure that the outer surface of the shock absorber pad body 1 can quickly return to a stable state and avoid internal imbalance.
[0036] The shock-absorbing pad body 1 is externally fixedly connected with anti-slip strips 20, and the number of anti-slip strips 20 is several groups arranged at equal intervals. The anti-slip strips 20 are made of wear-resistant material and their outer surface is roughened.
[0037] The working principle of the air-breathing shock-absorbing pad according to the embodiment is as follows: When the shock-absorbing pad is installed on a treadmill, the user's feet apply downward pressure to the main body 1 of the shock-absorbing pad as they run on it. At this time, the pressure is transmitted through the rubber block 4 and the connecting piece 5, thereby controlling the screw 6 to drive the pressure plate 7 to press downward, so that the shock-absorbing rubber 8 is subjected to force on both the upper and lower sides, thus squeezing inward. At this time, the gas inside the air cavity 10 can be discharged through the exhaust hole 11 through the squeezing. However, since the diameter of the exhaust hole 11 is small, the air cannot be discharged in time. Therefore, during this process, air pressure will quickly form inside the air cavity 10, thereby achieving an upward supporting force. This achieves a shock absorption and cushioning effect. During the compression of the shock-absorbing rubber 8, the sliding rods 13 on both sides slide symmetrically inside the mounting cylinder 12. At this time, the first spring 15 is compressed by the fixed rod, which can cooperate to buffer and absorb shock, improving the cushioning effect. When the main body 1 of the shock-absorbing pad is compressed, the second spring 18 installed inside it can also play a certain cushioning role. In addition, the damper 19 can maintain the stability of the structure. In summary, this device can form air pressure in the shock-absorbing rubber 8 for cushioning and shock absorption, and cooperate with multiple sets of spring structures for cushioning, which greatly improves the cushioning effect of the shock-absorbing pad and greatly improves the user's comfort.
