Abstract
Description
Technical Field
[0001] This utility model relates to the field of cushioning pad technology, and more specifically, to a novel hollow cushioning pad. Background Technology
[0002] In modern society, cushioning pads, as an important safety and comfort device, are widely used in various vehicle seats, sports equipment, furniture, industrial equipment, and construction. Traditional cushioning pads mostly use springs, foam plastics, or fluid-filled materials as shock-absorbing materials. While spring cushioning pads are simple in structure and low in cost, their response speed is slow when dealing with complex and varied impact forces, resulting in limited shock absorption. Furthermore, springs are prone to fatigue after long-term use, leading to performance degradation. Foam plastic cushioning pads, while having good shock absorption performance, have a difficulty in balancing density and hardness. Overly soft foam plastics may be comfortable but lack support, while overly hard foam plastics may cause injury to users. Fluid-filled cushioning pads can provide relatively uniform support, but their structure is complex, maintenance costs are high, and the fluid properties may change in extreme environments, affecting shock absorption.
[0003] Especially in applications requiring simultaneous vertical and horizontal impacts, such as sports field mats and vehicle seats, traditional cushioning pad designs prove inadequate. These applications often demand excellent shock absorption performance in the vertical direction while also providing some buffering capacity in the horizontal direction to cope with impacts from all directions. However, traditional cushioning pads often focus only on shock absorption in one direction, resulting in poor performance when dealing with complex impacts and a degraded user experience. Furthermore, while some high-end cushioning pads employ advanced materials and structural designs, such as pneumatic shock absorption systems or magnetic levitation technology, which improve shock absorption performance to some extent, their complex structure and high cost limit their widespread application. These high-end cushioning pads often require complex installation and maintenance processes, and repair costs are prohibitively high for ordinary users should a malfunction occur. Therefore, to address the aforementioned technical problems, a novel hollow cushioning pad is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a novel hollow cushioning pad. Through innovative structural design, it achieves efficient, economical, and multi-directional shock absorption and cushioning effects, providing an effective solution to the performance deficiencies of existing cushioning pads in complex impact environments.
[0005] This utility model is achieved through the following technical solution:
[0006] A novel hollow cushioning pad includes:
[0007] The buffer pad body has a first fixing plate fixedly connected to its inner side, a mounting base fixedly connected to the outside of the first fixing plate, a screw threadedly connected to the inner side of the mounting base, and a pressure plate fixedly connected to the end of the screw.
[0008] The shock absorber has slots on its upper and lower sides, and the pressure plate matches the slots. The inner side of the shock absorber has a cavity, which is spherical. The outer side of the shock absorber has an air inlet, which is connected to the cavity.
[0009] The buffer pillars are fixedly connected to the inner side of the buffer pad body, and there are several groups of buffer pillars arranged at equal intervals. A trapezoidal block is fixedly connected to the inner side of the buffer pad body, and the trapezoidal block abuts between two groups of buffer pillars.
[0010] A fixed rod is fixedly connected to the inner side of the buffer column. A fixed cylinder is fixedly connected to the outside of the fixed rod. A sliding rod is fixedly connected to the inside of the buffer column, and the end of the sliding rod is slidably connected to the inside of the fixed cylinder. A buffer mechanism is installed on the inside of the fixed cylinder.
[0011] Preferably, the number of the first fixing plates is several groups and they are arranged symmetrically.
[0012] Preferably, the cavity is made of rubber material, the buffer column is spherical, and the opening of the trapezoidal block of the vent hole is much smaller than the inner diameter of the buffer column.
[0013] Preferably, both the shock-absorbing block and the buffer column are made of rubber material.
[0014] Preferably, the buffer column is a hollow cylindrical structure.
[0015] Preferably, the fixing rod coincides with the central axis of the buffer column.
[0016] Preferably, the number of fixed cylinders is four sets arranged in a ring.
[0017] Preferably, the buffer mechanism includes a second fixed plate, a spring, and a limiting rod. The second fixed plate is fixedly connected to the end of the slide rod and slidably connected to the inner side of the fixed cylinder. The spring is fixedly connected to the outside of the fixed cylinder and the second fixed plate. The limiting rod is fixedly connected to the fixed cylinder and the spring is sleeved on the outside of the limiting rod. The spring and the fixed plate are close to each other.
[0018] The technical solution of this utility model has at least the following beneficial effects:
[0019] 1. When this novel hollow buffer pad is used, its outer surface is pressed. At this time, the pressure is transmitted through the first fixed plate and the mounting base, thereby controlling the screw to drive the pressure plate downward, so that the upper and lower sides of the shock absorber block are subjected to force, thus squeezing inward. At this time, the gas inside the cavity can be squeezed out through the air inlet. However, since the diameter of the air inlet is small, the air cannot be discharged in time. Therefore, during this process, air pressure will be quickly formed inside the cavity, thereby achieving an upward supporting force and realizing the shock absorption and buffering effect.
[0020] 2. This new type of hollow buffer pad, when subjected to pressure, can cushion the impact by squeezing the internal buffer columns, utilizing the material properties of the buffer columns themselves. Furthermore, the vertical sliding rod can be controlled to drive the spring for cushioning. Additionally, the trapezoidal block design converts downward pressure into lateral pressure on the buffer columns, which can also be cushioned by the horizontal sliding rod driving the spring. This greatly enhances the buffer pad's cushioning capacity. Moreover, the presence of a limiting rod inside the fixed cylinder, close to the second fixed plate, effectively limits the downward pressure of the buffer pad, preventing excessive shaking when people walk on it.

[0027] 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 skilled in the art without creative effort are within the scope of protection of this application.
[0028] Example
[0029] Please see Figure 1-5 This application discloses a novel hollow cushioning pad, comprising:
[0030] The buffer pad body 1 has a first fixing plate 2 fixedly connected to its inner side, and a mounting base 3 fixedly connected to the outer side of the first fixing plate 2. The mounting base 3 is set to facilitate the installation of the screw 4, so as to facilitate installation and disassembly. The screw 4 is threadedly connected to the inner side of the mounting base 3, and a pressure plate 5 is fixedly connected to the end of the screw 4.
[0031] The shock absorber 6 has slots 7 on its upper and lower sides, and the pressure plate 5 matches the slots 7. The inner side of the shock absorber 6 has a cavity 8, which is spherical. The outer side of the shock absorber 6 has an air inlet 9, which is connected to the cavity 8.
[0032] The buffer pillars 10 are fixedly connected to the inner side of the buffer pad body 1, and there are several groups of buffer pillars 10 arranged at equal intervals. A trapezoidal block 11 is fixedly connected to the inner side of the buffer pad body 1, and the trapezoidal block 11 abuts between two groups of buffer pillars 10.
[0033] A fixed rod 12 is fixedly connected to the inner side of the buffer column 10. A fixed cylinder 13 is fixedly connected to the outside of the fixed rod 12. A sliding rod 14 is fixedly connected to the inside of the buffer column 10, and the end of the sliding rod 14 is slidably connected to the inside of the fixed cylinder 13. A buffer mechanism is installed on the inside of the fixed cylinder 13.
[0034] The number of first fixing plates 2 is several groups arranged symmetrically, the cavity 8 is made of rubber material, the buffer column 10 is spherical, and the opening of the exhaust hole trapezoidal block 11 is much smaller than the inner diameter of the buffer column 10.
[0035] Both the shock absorber 6 and the buffer column 10 are made of rubber material, so the shock absorber 6 and the buffer column 10 can also achieve the buffering function.
[0036] The buffer column 10 is a hollow cylindrical structure, and the fixing rod 12 coincides with the central axis of the buffer column 10, which facilitates symmetrical design and maintains internal balance.
[0037] The number of fixed cylinders 13 is four sets arranged in a ring, which can provide buffering in both horizontal and vertical directions, greatly improving the buffering effect.
[0038] The buffer mechanism includes a second fixed plate 15, a spring 16, and a limiting rod 17. The second fixed plate 15 is fixedly connected to the end of the slide rod 14 and slidably connected to the inner side of the fixed cylinder 13. The spring 16 is fixedly connected to the outside of the fixed cylinder 13 and the second fixed plate 15. The limiting rod 17 is fixedly connected to the fixed cylinder 13 and the fixed cylinder 13, and the spring 16 is sleeved on the outside of the limiting rod 17. The spring 16 and the second fixed plate 15 are close to each other.
[0039] The working principle of the novel hollow buffer pad based on the embodiment is as follows: when the outer surface of the buffer pad is under pressure, the pressure is transmitted through the first fixed plate 2 and the mounting base 3, thereby controlling the screw 4 to drive the pressure plate 5 to press down, so that the shock absorber 6 is subjected to force on both the upper and lower sides, thereby squeezing inward. At this time, the gas inside the cavity 8 can be squeezed out through the air inlet 9. However, since the diameter of the air inlet 9 is small, it cannot expel the air in time. Therefore, during this process, air pressure will be quickly formed inside the cavity 8, thereby achieving an upward supporting force, thus achieving the effect of shock absorption and buffering.
[0040] Furthermore, when the buffer pad is subjected to pressure, the internal buffer column 10 can be squeezed to provide cushioning through its material properties. Additionally, the vertical slide rod 14 can be controlled to drive the spring 16 for cushioning. Moreover, due to the design of the trapezoidal block 11, the downward pressure is converted into lateral pressure on the buffer column 10, which can be further cushioned by the horizontal slide rod 14 driving the spring 16. This greatly improves the cushioning capacity of the buffer pad. Furthermore, since a limiting rod 17 is installed inside the fixed cylinder 13 that is close to the second fixed plate 15, it can limit the downward pressure of the buffer pad and prevent excessive shaking when people walk on the buffer pad.
[0041] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
