A reinforcement structure of safety helmet and a manufacturing method thereof. The reinforcement structure includes a helmet body formed of a cushion foam material; and a structure body integrated with the helmet body. The structure body is a texture at least composed of multiple strip members arranged in an array. The structure body is formed with a substantially cellular structure. The helmet body is defined with a top section and a peripheral section and the structure body is defined with a first section and a second section connected to the first section corresponding to the top section and peripheral section of the helmet body. The cushion foam material is injected into a molding module to enclose the first and second sections to form an integrated complex reinforcement structure, which is easier to manufacture and has higher structural strength, lighter weight and higher security.
