Definitions

  • the present invention relates to a sports helmet, and specifically, to a steam-formed double-layer shock-absorption sports helmet, which belongs to the technical field of sports equipment.
  • a safety helmet is a fitting for protecting head of people.
  • vehicle-used helmet or baseball sport helmets and other sports helmets are indispensable tools for people in transportations or sports.
  • Most of helmets are generally in a semicircular shape and each includes a shell and a liner.
  • a shock absorption structure is arranged between the shell and the liner. This structure is required to have certain hardness, anti-hitting performance, certain softness and certain cushioning performance.
  • the existing shock absorption structure employs the following manner: the liner of the structure is made of EPS that is a high-density material. Although the EPS material has a little elasticity, the hardness is high so the shock absorption effect is poor.
  • FR 2 379 262 discloses a helmet with a shock-absorption layer comprising a layer of expanded polyethylene (EPE) and a layer of expanded polystyrene (EPS).
  • EPE expanded polyethylene
  • EPS expanded polystyrene
  • WO 2016/112987 discloses a helmet with a shock-absorbing layer comprising expanded polystyrene (EPS) or expanded polypropylene (EPP).
  • EPS expanded polystyrene
  • EPP expanded polypropylene
  • the present invention aims at solving the technical problems that the helmet cannot have both the anti-hitting capability and the softness and is poor in use comfort by providing a steam-formed double-layer shock-absorption sports helmet.
  • the steam-formed double-layer shock-absorption sports helmet of the present invention includes a helmet body; the helmet body includes a surface hard shell, an EPS material layer and an EPP material layer; the surface hard shell, the EPS material layer and the EPP material layer are successively mounted in a fitting manner; the surface hard shell is wrapped on an outer surface of the EPS material layer; and the EPP material layer is wrapped on an inner surface of the EPS material layer.
  • the EPS material layer is made of an EPS material.
  • the EPP material layer is made of an EPP material.
  • the steam-formed double-layer shock-absorption sports helmet consists of the surface hard shell, the middle EPS material layer and the lower EPP material layer, has good anti-hitting performance, water resistance, heat resistance and thermal insulation properties.
  • 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.
  • the EPP material layer has light weight, so that the article weight can be greatly reduced.
  • 1 helmet body
  • 2 hard surface shell
  • 3 EPS material layer
  • 4 EPP material layer
  • a steam-formed double-layer shock-absorption sports helmet includes a helmet body 1; the helmet body 1 includes a surface hard shell 2, an EPS material layer 3 and an EPP material layer 4; the surface hard shell 2, the EPS material layer 3 and the EPP material layer 4 are successively mounted in a fitting manner; the surface hard 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.
  • the EPS material layer 3 is made of an EPS material.
  • the EPP material layer 4 is made of an EPP material.
  • the present invention relates to a helmet used for cycling sports and outdoor sports, and in particular relates to an EPP structure for a helmet, which can achieve a shock-absorption and cushioning effect, and is suitable for vehicle-used helmets, baseball sports helmet and other sports helmets.
  • the helmet mainly consists of the surface hard shell 2, the middle EPS material layer 3 and the lower EPP material layer 4; the surface hard shell 2 is mainly used to resist the external hit; the EPS material layer 3 is mainly made of an expandable polystyrene material and has functions of water resistance, heat resistance and heat insulation, thereby effectively improving the wearing comfort; the EPP material layer 4 is mainly made of a polypropylene plastic foam material, has good shock resistance and energy absorption performance, high deformation recovery rate and good heat resistance, oil resistance and thermal insulation properties; and furthermore, the EPP material layer has light weight, so that the article weight can be greatly reduced.
  • the steam-formed double-layer shock-absorption sports helmet consists of the surface hard shell, the middle EPS material layer and the lower EPP material layer, has good anti-hitting performance, water resistance, heat resistance and thermal insulation properties. Moreover, the EPP material layer having the characteristics of 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.
