Abstract

La présente invention se rapporte au domaine technique des plaques écologiques. L'invention concerne une plaque élastique écologique, qui comprend une première couche de surface et une deuxième couche de surface, une couche centrale élastique d'amortissement étant disposée entre la première couche de surface et la deuxième couche de surface, et la couche centrale d'amortissement étant pourvue à l'intérieur d'une pluralité d'espaces d'amortissement pour l'amortissement. Dans la plaque élastique écologique, la couche centrale d'amortissement formée par liaison mutuelle d'une pluralité de matériaux écologiques incurvés d'amortissement est disposée entre la première couche de surface et la deuxième couche de surface, et la pluralité d'espaces d'amortissement est formée dans la couche centrale d'amortissement ; au moyen de la coopération mutuelle entre la couche centrale d'amortissement, qui est reliée à une couche résistante aux chocs, et la couche résistante aux chocs, qui est formée en reliant mutuellement deux plaques incurvées résistant aux chocs ayant des sommets plus denses et est reliée à la première couche de surface et à la deuxième couche de surface, un support plus dense est fourni par la couche incurvée résistant aux chocs pour la première couche de surface ou la deuxième couche de surface, de façon à améliorer la résistance aux chocs de la première couche de surface et de la deuxième couche de surface. La couche centrale d'amortissement peut améliorer la performance élastique, et la combinaison desdites deux performances peut mieux protéger un produit.
