Omni-directional anti-collision structure of safety helmet

Abstract

The invention discloses an omnidirectional crashproof structure for a safety helmet. The structure includes a shell and a combination of a filler and an elastic carrier enclosed in the shell. The elastic carrier is provided with a wall forming a skeleton structure and a plurality of well-shaped structure regions, defined by the wall, with geometric contours. Protruding wings are formed on peripheral regions of the well-shaped structure regions (or directions toward the centers of the well-shaped structure regions) to make each well-shaped structure region define a first region, a second regionand an accessory region connected between the first region and the second region. Furthermore, the filler connects the shell and the elastic carrier to form an integral form. Under the condition of improving the strength of the whole structure, the elastic carrier can produce flexible deformation effects of different degrees according to different head shape contours, and so functions of comprehensively covering heads, cushioning, absorbing and transmitting external crash force, increasing wearing comfortableness and fitness and the like can be achieved.

Description

technical field [0001] The present invention relates to an omnidirectional anti-collision structure of a safety helmet; in particular, it relates to a combined design of an application (cushion foam) filler combined with a shell and an elastic carrier, and the elastic carrier has a wall forming a skeleton structure and a plurality of geometric shapes Contoured well-shaped structure area, composite molding technology of a monolithic structure. Background technique [0002] It is an existing technology to use a plastic shell to form an impact-resistant filler formed by heating a foam material, and make the plastic shell tightly cover and bond the foam filler to complete a safety helmet or helmet structure. For example, U.S. Patent No. 4466138 "Safety Helmet with A Shell Injected from Thermoplastics And Method for The Manufacture of Said Helmet" and Taiwan No. 85101810 "Method for Manufacturing Safety Helmet" provide typical embodiments. [0003] The structure of this type of ...

Problems solved by technology

A problem related to the structural characteristics and application of this type of thin-layer liner is that the addition of a thin-layer liner inside the safety helmet not only increases the troublesome situation of the assembly process, but also its material properties and thin-layer structure cannot be effectively improved. Wearing comfort for the user or reducing the stuffiness of wearing for a long time

[0005] At the same time, limited by the structure and characteristics of the thin-layer liner, in order to increase the coverage and fit between the interior of the safety helmet and the wearer's head as much as possible, it is necessary to provide different pads according to the size of the wearer's head in practice. Specifications of helmet products significantly increase the production cost; and this situation is not what we expected

[0006] Another problem related to the structural type and application of this type of safety helmet combined thin-layer liner is that even if the existing helmets provide helmet products of different sizes, it is still impossible to make the helmet and thin-layer liner compatible with different wearers. The entire head shape contour or the curved surface of the head form a real comprehensive coverage and fit

[0007] That is to say, although existing safety helmets are provided with different sizes or specifications, they cannot fully conform to the entire head shape contour or head arc surface of the wearer's head in three-dimensional directions; Coverage and fit on the wearer's head

This will affect the protection and safety of the wearer's head when the wearer's head is impacted by external forces.
