ETPU (expanded thermoplastic polyurethane) is a foamed thermoplastic polyurethane particle having a closed cell structure. The high-elasticity high-resilience wear-resistant rubber has the characteristics of high elasticity, excellent resilience, good wear resistance, high tensile strength, good chemical stability, environmental friendliness and the like, and is still very soft and rich in elasticity at extremely low temperature. Although ETPU has better wear resistance, the cushion using the ETPU is easily scratched by sharp tools such as blades and the like at present. Here the utility model discloses to the cushion of using ETPU further improvement to solve the cushion and easily by the problem of sharp weapon fish tail.

Please refer to fig. 1, which is a schematic structural diagram of a seat cushion according to an embodiment of the present invention. The seat cushion 1 can be applied to a vehicle such as a sharing bicycle, a sharing moped, a wheelchair, a tricycle, a motorcycle, an automobile or an electric vehicle or a sofa. The seat cushion 1 includes: a skin layer 11, an ETPU layer 12, and a base plate 13. In some embodiments, the thickness of the ETPU layer 12 is greater than or equal to 5mm and less than or equal to 30mm, and is within the thickness, so that the stability of the cushion performance can be ensured, the cushion is not too thick, the weight does not exceed the normal standard, and better use experience can be provided for users. Wherein, the surface layer 11 is usually made of leather or cloth material. The surface layer 11 and the ETPU layer 12 can be glued to form an integral detachable structure and mounted on the bottom plate 13, that is, the surface layer 11 and the ETPU layer 12 adopt an integral detachable structure. The surface layer 11 is preferably a leather layer; or selecting ETPU or EVA with good elasticity, good resistance to damage and no water absorption.

In other embodiments, when the seat cushion 1 is a sports seat cushion, the center of the front end of the seat cushion 1 is hollow, for example, the ETPU layer 12 may also be hollow. The ETPU layer 12 is arranged adjacent to the bottom 111 of the surface layer, and the bottom 121 of the ETPU layer is divided into a plurality of modules 1211; in some embodiments, the ETPU layer 12 is adhesively secured to the skin layer 11 by, but not limited to, water vapor, PU foam, or glue. In one embodiment, the ETPU layer 12 may be a unitary structure, i.e., the modules 1211 are integrally formed with the remainder of the ETPU layer 12 using a mold. In one embodiment, the ETPU layer 12 may be formed by gluing a plurality of modules 1211 to the bottom of an ETPU layer 12.

The bottom plate 13 is disposed adjacent to the bottom 121 of the ETPU layer.

Namely, the bottom 121 of the ETPU layer is divided into a plurality of modules 1211, the bottom 121 of the ETPU layer is designed in a modularized mode, interaction force among foaming particles is dispersed, and the cushion is softer. The foaming polyurethane can be skinned at the position contacting with the grinding tool, the skinning physical and mechanical properties are very good, the module 1211 is an independent module, when the cushion is scratched, the plurality of independent modules have a blocking effect on the blades, and the irregular arrangement of the module 1211 prevents the blades from being scratched to the gaps, so that the blades are prevented from being damaged greatly when being scratched to the end. Meanwhile, the modules 1211 can well buffer the pressure on the surface layer 11, relieve the pain of the buttocks caused by bumping and the like during riding of a user, and improve the user experience. In addition, the upper surface of the ETPU layer 12 is a complete layer, and the ETPU itself has good scratch resistance, i.e., the upper surface of the ETPU layer 12 is not easily damaged by ordinary knife cutting. On the other hand, the ETPU has good hydrophobicity, so that even if the upper surface of the ETPU layer 12 is damaged, the ETPU layer can not store water, and a large amount of water can not emerge to wet trousers and skirts when the cushion is pressed.

The shape of the module 1211 may include one or more of the following: trilateral, quadrilateral, pentagonal, and hexagonal or hexagonal. And the bottom 121 of the ETPU layer may be formed by one or more shaped modules 1211 when applied, that is, the bottom 121 of the ETPU layer may be formed by one shaped module 1211 or by a plurality of different shaped modules 1211, which is not limited herein.

In some embodiments, the shapes of the modules 1211 can be selected to be combined according to the stress points and the stress deformation difficulty of different parts, so as to reduce the deformation and the aging of the cushion as much as possible. For example, in one embodiment, the stressed portion is honeycomb hexagonal and the other unstressed portion is circular. Or in another embodiment, the arrangement density of the modules 1211 may be the same, or in another embodiment, the effect of reducing deformation and aging of the cushion may be achieved by the arrangement density of the modules 1211, that is, the distribution density of the modules 1211 is in direct proportion to the stress degree thereof, the region with large stress is dense, the region with small stress is sparse, and the design rationality of the cushion and the comfort for the user are further improved. The module 1211 can adjust the shape and density of each position according to the stress condition to obtain better riding experience.

As shown in fig. 2, in order to further improve the elasticity of the seat cushion 1, to improve the damping effect, and to improve the comfort of the user during use, the seat cushion 1 further includes a foaming layer 14 disposed between the ETPU layer 12 and the bottom plate 13.

Wherein the foamed layer 14 may be composed of at least one layer of an elastic filler. And the foamed layer 14 may be comprised of one or more elastomeric fillers. Also, the ETPU layer 12 may be bonded to the foam layer 14 (e.g., by glue), or the ETPU layer 12 may be formed integrally with the foam layer 14 by secondary casting. That is, the ETPU layer 12 is poured first, and after solidification, the foaming layer 14 is poured, and the expansion process of the foaming material will fill the gaps of the modules 1211 of the ETPU layer 12 poured before, so as to achieve the effect of engagement. The ETPU layer 12 can well relieve the deformation of the single foaming layer 14 after long-term use, and improve the comfort of the cushion.

Referring to fig. 3, a schematic view of the application of the cushion of the present invention in one embodiment is shown. The cushion 1 includes a surface layer 11, an ETPU layer 12, a bottom plate 13, and a foam layer 14. The ETPU layer 12 is disposed adjacent to the bottom 111 of the skin layer; the foamed layer 14 is disposed adjacent to the bottom 121 of the ETPU layer; the base plate 13 is disposed adjacent to the bottom of the foamed layer 14. Through bottom 121 at the ETPU layer set up foaming layer 14 can improve the elasticity of cushion as far as possible through the elasticity on foaming layer, strengthen the cushion travelling comfort under the state of riding of jolting, improve user experience. In some embodiments, the bottom 111 of the ETPU layer shown in fig. 3 may be divided into a plurality of modules, i.e., to form the structure of the cushion 1 shown in fig. 2.

In some embodiments, the upper surface of the ETPU layer 12 and/or the lower surface of the ETPU layer 12 are sloped. Such as the seat cushions shown in fig. 1-3. Wherein the gradient is, for example, 0-5 °. Whether the ETPU layer 12 is provided with the slope and the setting size of the slope can be adjusted according to the aging degree of the actual cushion pressed deformation, and the setting is not limited by whether the module 1211 or the foaming layer 14 is arranged at the bottom of the ETPU layer 12. When the lower surface of the ETPU layer 12 is sloped, the upper surface of the adjacently disposed foam layer 14 is also correspondingly sloped to better conform to the ETPU layer 12. When the upper surface of the ETPU layer 12 is sloped, the upper surface of the adjacently disposed foam layer 14 may be a planar layer to better conform to the lower surface of the ETPU layer 12. Additionally, in some embodiments, both the lower surface of the ETPU layer 12 and the lower surface may be provided with a slope to provide better comfort and aging resistance.

In some embodiments, the thickness of the front end of the ETPU layer 12 is designed to be greater than the thickness of the rear end of the ETPU layer 12, such as the seat cushions shown in fig. 1-3. The front end of the ETPU layer 12 and the rear end of the ETPU layer 12 are divided according to the installation direction of the seat cushion 1, the portion of the seat cushion 1 close to the handlebar is the front end of the ETPU layer 12, and the portion of the seat cushion 1 away from the handlebar is the rear end of the ETPU layer 12. Wherein the thickness of the front end of the ETPU layer is 1-2mm thicker than the thickness of the tail end of the ETPU layer. Here, the function of setting the front end of the ETPU layer 12 to have a higher thickness is similar to the effect of setting the upper surface of the ETPU layer 12 and/or the lower surface of the ETPU layer 12 to have a slope with a certain slope in the above embodiment, and details are not repeated here.

In some embodiments, the depth of the module 1211 disposed at the bottom of the leading end of the ETPU layer 12 is less than the depth of the module 1211 disposed at the bottom of the trailing end of the ETPU layer 12. Thereby relieving the situation that the front end of the cushion 1 collapses after long-term use. The depth described herein refers to the depth of the gap opening between the modules 1211.

For example, the depth of the module 1211 disposed at the bottom of the front end of the ETPU layer 12 is 0.5-5mm smaller than the depth of the module 1211 disposed at the bottom of the rear end of the ETPU layer 12; wherein the depth of the module 1211 is related to the density of the distribution of the module 1211. For example, the denser the distribution of the modules 1211, the smaller its corresponding depth.

The present invention is further described with reference to the following specific examples, and fig. 4 is a schematic view illustrating an application of the cushion according to an embodiment of the present invention. In this embodiment, the seat cushion 2 is applied to a shared bicycle or a shared moped, and fig. 4 is an exploded view of the seat cushion 2, wherein the seat cushion 2 includes: a skin layer 21, an ETPU layer 22, a foam layer 23, and a base plate 24. Wherein the thickness of the ETPU layer 22 is greater than or equal to 5mm and less than or equal to 30 mm. The surface layer 21 and the ETPU layer 22 are glued to form a whole and are detachably arranged on the foaming layer 23.
