New description: [New technical field] This creation is related to lightweight and flexible cushioning, especially for a cushioning element in which most foaming particles are buried in the elastomer to reduce weight. [Prior Art] A cushioning element generally used in footwear, sports equipment, or computer peripherals, usually by the elasticity of the material itself to form a shock absorbing effect and protect the user. This type of cushioning element is generally of a single individual type, such as Artemisin (GEL), etc., of a single material. However, this type of cushioning element usually has problems of being soft but not strong enough, and therefore often breaks when subjected to strong external force. Furthermore, cushioning elements made of a single material such as Arthur Glue have considerable weight and are not conducive to the current trend of lightweight design of sports equipment. The improved cushioning element developed in the foregoing case is a conventional airbag structure on the market, and the manufacturer of the general airbag hopes that the airbag can be provided with multiple advantages of good elasticity, good strength and light weight. . However, in actual use, the airbag must directly withstand a relatively large impact force, especially when the airbag is placed in the sole. Because of the M339607, the outer layer of the airbag must be designed to have a considerable strength, but this will make it impossible to fully exert its elasticity when subjected to pressure. In order to overcome the lack of the aforementioned conventional cushioning elements, the creator of the present invention has previously developed a composite cushioning element (2) which is light in weight and excellent in cushioning effect, and has been approved by the Office of the Patent Publication No. 259868, which is a composite cushioning element system. The cover body, the elastic core body, the bridge film and the air bag are coated on the outer side of the elastic core body, and the bridge thin film is interposed between the elastic core body and the cover body to form a The active interface layer, the inner hollow air bag is disposed in the elastic core body. Thereby, the weight can be reduced by the airbag and the cushioning effect is excellent. In practical manufacturing, the airbag is placed in a mold for manufacturing the elastic core before, and then the liquid elastic core material is poured into the mold, and the elastic material is solidified to obtain the desired elasticity. Core body. However, in the process of solidification of the elastic core material, due to the light weight and large volume of the airbag, the lightweight airbag can easily float to the upper position of the mold, resulting in the elastic core wrapped around the airbag. Uneven thickness • Even, it may even cause a thin layer of elastic core on one side of the airbag. This uneven structure is likely to cause uneven dispersion of the cushioning element on a large airbag. It may also cause a problem that the cushioning member is broken after being stressed. On the other hand, such a multi-layered composite cushioning element must be pre-manufactured by the 6 M339607 process, so that the overall manufacturing process is large, and the manufacturing cost is also difficult to reduce. Therefore, the aforementioned composite buffer element structure is in need of further improvement. [New Content] ^ The main purpose of this creation is to solve the above problems and provide a cushioning element that is lightweight and meets the requirements of both elasticity and strength. For the purpose of the foregoing, the cushioning element of the present invention is intended to comprise: an elastomer which is a solid material made of a material having elasticity; a plurality of particles, which are made of an expandable polymer and embedded in the elasticity Inside the body. Since the expandable polymer is both bulky and lightweight, it is possible to achieve weight reduction by replacing the weight of the same volume of the elastomer with the foamed particles embedded in the elastomer. ® In addition, the swellable polymer is mixed into the 'raw material of the elastomer when it is not foamed, and then poured into the mold, and foamed into particles during the heating process of the elastomer molding, thereby simplifying the process. And reduce manufacturing costs. In addition, the granules of the swellable polymer can provide a buffering capacity different from that of the elastomer, so that the entire cushioning member has multiple buffer layers of different elastic coefficients at the same time, and the cushioning effect can be improved. 7 M339607 The above and other objects and advantages of the present invention will be readily understood from the following detailed description of the embodiments and the accompanying drawings. Of course, the present invention may be different in some of the parts, or the arrangement of the parts, but the selected embodiments are described in detail in the present specification, and the construction thereof is shown in the drawings. [Embodiment] _ Please refer to FIG. 1 and FIG. 2, FIG. 1 is a schematic view of the appearance of the embodiment, and FIG. 2 is a schematic cross-sectional structural view of the present invention. The cushioning element 1 of the present invention is composed of a covering body 11 covered with an elastic body 12, and a plurality of particles 2 are embedded in the elastic body 12. The covering 11 is a solid made of a material fused with the elastic body 12 and has suitable toughness; the elastic body 12 is a solid having a predetermined shape and good elasticity; and most of the particles 2 are It is made of a swellable polymer. • According to the actual test results, the covering 11 is made of polyurethane, which is suitable for its malleability and toughness. The elastomer 12 may be a polyurethane resin obtained by combining an appropriate amount of a polyhydric alcohol with a polyisocyanate, and the weight ratio of the two is preferably between 100:5 and 100:20. Each of the particles 2 is made by foaming polystyrene (EPS) as a main material. In addition to foamed polystyrene (EPS), the material of the pellets can also be foamed by foaming 8 M339607 ♦ propylene (EPP), blister polyethylene (EpE) or foamed polylactic acid (). Everything can be. In the process of clothing 4 of Beiwu, the Department of Creation first fully blended the blended elastomeric materials with the unformed materials, and then poured them into the mold, and then, '吏八处; 2G l〇GC environment In the process, the granular material is foamed and expanded to form particles, 2 and the elastomer raw material is condensed into a solid elastomer η; and then sprayed, coated or soaked, so that a proper amount of liquid coating material is attached to the elastic The outer edge of the body forms a cushioning element by creating a firm bond between the elastomer of the polyamine lysate and the coating of the polyamine S material. & In the process of solidifying the raw material of the raw material, the granules can be expanded until the elastomer raw material is not solidified, such as =^_ is equal to the expandable polymerization. The bulk of the elastomeric material of the bulk of the material is replaced by the same volume of the elastomer and the granules 2 after the hair/package to effectively reduce the weight of the elastomer 12. Float: However, the particle 2 may also be placed at a position above the mold, and the body is cut by M, and its volume is proportional to the viscosity of the material of the bulk material. Therefore, the particle 2 is bombarded. The situation of the second will be reported slightly. Even if some of the particles are in the 2 position = uniformity in the elastic body 12, the effect of the dispersion of the old body 12 (4) is not affected. M339607 The above-mentioned covering body 11 can be completely covered on the entire surface of the elastic body 12. In practical use, it can also be laminated on the elastic body 12 in an appropriate thickness. A part of the surface, or concentrated in a small part with a considerable area. That is, the covering body 11 can be covered only with a portion that can withstand an external force. Please refer to Figure 3, which is a schematic diagram of the creation and dispersion of external forces. When the cushioning member 1 is subjected to the external force P, the cushioning member 1 first absorbs and disperses a part of the external force by the covering body 11 and the elastic body 12; and then, by the plurality of particles dispersed in the elastic body 12, respectively 2 Interacting with the elastic body 12 to absorb and disperse the external force, so that the external force is continuously weakened to achieve the buffering effect. Since each of the particles 2 is made by expanding the expansion of the expandable polymer by several tens of times, each of the particles 2 has a good buffering capacity different from that of the elastomer 12, and the particles 2 interact with the elastomer 12 to absorb external forces. Under the action of the device, the buffer element of the present invention can have multiple buffer coefficients of different elastic coefficients at the same time, and the cushioning effect can be improved. Further, the swellable polymer of the granule is mixed into the raw material for manufacturing the elastic body when not foamed, and then poured into the mold, and is foamed into the granule 2 during the heating process of the solidification molding of the elastomer, so that Effectively streamline processes and reduce manufacturing costs. Further, in practical use, the elastomer 12 can be modified with a thermoplastic material or a thermosetting material M339607 as the main material in addition to the above-mentioned polyurethane resin material, so that the same effects as those of the foregoing embodiment can be achieved. From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objectives, and it has been in compliance with the provisions of the Patent Law and has filed a patent application.
