Steam-formed double-layer shock-absorption sports helmet

Abstract

The present invention discloses a steam-formed double-layer shock-absorption sports helmet, including a helmet body. The helmet body includes a surface hard shell, an EPS material layer and an EPP material layer successively mounted together in a fitting manner. The surface hard shell is wrapped on an outer surface of the EPS material layer. The EPP material is wrapped on an inner surface of the EPS material layer. The EPS material layer is made of an EPS material and the EPP material layer is made of an EPP material. The present invention has good anti-hitting performance, water resistance, heat resistance and thermal insulation properties. Moreover, the EPP material layer with good shock resistance and energy absorption properties, high deformation recovery rate, and good heat resistance, oil resistance and thermal insulation properties is used. Furthermore, the EPP material layer has light weight, so that the article weight can be greatly reduced.

What is claimed is: 
     
         1 . A steam-formed double-layer shock-absorption sports helmet, comprising a helmet body ( 1 ), wherein the helmet body ( 1 ) comprises a hard surface shell ( 2 ), an EPS material layer ( 3 ) and an EPP material layer ( 4 ); the hard surface shell ( 2 ), the EPS material layer ( 3 ) and the EPP material layer ( 4 ) are successively mounted together in a fitting manner; the hard surface shell ( 2 ) is wrapped on an outer surface of the EPS material layer ( 3 ), and the EPP material layer ( 4 ) is wrapped on an inner surface of the EPS material layer ( 3 ). 
     
     
         2 . The steam-formed double-layer shock-absorption sports helmet of  claim 1 , wherein the EPS material layer ( 3 ) is made of an EPS material. 
     
     
         3 . The steam-formed double-layer shock-absorption sports helmet of  claim 1 , wherein the EPP material layer ( 4 ) is made of an EPP material.
