Abstract
The utility model discloses a safety helmet shell structure, which is characterized in that a concave-convex structure is formed on the inner surface of a shell. With the concave-convex structure, and when the safety helmet is impacted, the acting time which is changed by the speed can be greatly prolonged (i.e. improve delta t), and the acceleration (the value of a) can be reduced so as to reduce the acting force (the value of F); therefore, the concave-convex structure can improve the rigidness of the shell and increase the contact area between the shell and a buffering layer inside the safety helmet so as to realize the buffering effect and to absorb more impact energy, so the head of the human body can be effectively protected; moreover, under the requirement of the same impact resistance, the shell adopting the concave-convex structure can reduce the application quantity of the shell material, reduce the weight of the safety helmet and can improve the application comfort.
Description
Technical field
The utility model is the safety cap structure about composite or injection mo(u)lding, is meant a kind of safety cap cap shell structure especially.
Background technology
In many occasions, since dangerous higher, therefore must cap safe in utilization.When safety cap can be subjected to clashing at people's head, farthest protect head to preserve from, this just needs the cap shell of safety cap must have high strength.Yet the intensity of cap shell but is not high more good more, and on the contrary, the dealer makes the cap shell break behind the powerful external force collision being subjected to when design cap shell usually, could eliminate maximum energy like this.Its reason is: according to mechanics principle, and directed force F=ma (m is a quality, and a is an acceleration), wherein quality is an invariant, so desire reduces and to make firmly F, and a is diminished; And a=Δ V/ Δ t (Δ V is a velocity variable, and Δ t is a time variation amount), wherein velocity variable can't change, and therefore will reduce acceleration, the action time of just necessary prolongation power; That is to say, in the process that the cap shell breaks, just can prolong action time, thereby reduce impulsive force, make head be subjected to as far as possible little injury.Here it is, and the said in the industry safety cap that can not break not is best safety cap.
But, though the dealer can eliminate energy by the mode that makes safety cap cap shell destroy, can when practical application, but as one wishes not to the utmost.This be because: it is limited after all that the cap shell destroys the time that can prolong, so when being subjected to strong impact force, still can't effectively protect head.For improving the impact resistance of safety cap cap shell, mostly the dealer is to realize by the thickness that increases the cap shell, but this certainly will cause the increase of cap shell weight, the raising of material cost.
The utility model content
The purpose of this utility model is to provide a kind of shock resistance effect that can effectively promote the cap shell, reduces the safety cap cap shell structure that cap shell weight reaches the economical with materials cost simultaneously.
For achieving the above object, technical solution of the present utility model is:
A kind of safety cap cap shell structure, wherein: be to be formed with concaveconvex structure at cap shell inner surface.
Described cap shell also is provided with lower jaw, and the lower jaw inner surface also is formed with concaveconvex structure.
Described concaveconvex structure is the total inner surface that is formed at cap shell or lower jaw.
Described concaveconvex structure is the local location that is formed at cap shell or lower jaw inner surface.
Described concaveconvex structure is the rib that is formed at cap shell or lower jaw inner surface.
Described concaveconvex structure is protruding grain, concave point or the pit that is formed at cap shell or lower jaw inner surface.
Described pit is circle, quadrangle or polygon.
Described concaveconvex structure is the projection that is formed at cap shell or lower jaw inner surface protrusion.
Described projection is circle, quadrangle or polygon.
After adopting such scheme, because the cap shell inner surface of the utility model safety cap forms concaveconvex structure, when safety cap was subjected to impacting, it is the action time (promptly improving Δ t) of extending speed change greatly, reach and reduce acceleration (a value), and then reduce active force (F value), therefore, this concaveconvex structure can promote cap shell rigidity, the contact area of cushion in increase and the safety cap, reach the effect of buffering, absorb more impact energy, allow human body head be effectively protected; And under equal shock resistance required, the cap shell of employing concaveconvex structure can reduce the use amount of cap shell material, reduces the weight of safety cap, improves the comfortableness of using.

Fig. 2 is the sectional view of the utility model embodiment one cap shell;
Fig. 3 is the structural representation of the utility model embodiment two;
Fig. 4 is the sectional view of the utility model embodiment two cap shells.
The specific embodiment
Safety cap cap shell structure of the present utility model, it mainly is to be formed with concaveconvex structure on the inner surface of cap shell, if the cap shell also is provided with lower jaw 3, then also is formed with concaveconvex structure on the inner surface of lower jaw 3.
As shown in Figure 1, 2, be the utility model embodiment one: the concaveconvex structure of cap shell 1 and lower jaw 3 inner surfaces is the regular hexagon pit 2 that is clouded on the inner surface.
Shown in Fig. 3,4, be the utility model embodiment two: the concaveconvex structure of cap shell 1 and lower jaw 3 inner surfaces is the circular concave point 3 that is clouded on the inner surface.
Certainly, above-mentioned concaveconvex structure is the total inner surface that is distributed in cap shell 1 and lower jaw 3, also can be at the local location that is distributed in cap shell 1 and lower jaw 3 inner surfaces.And this concaveconvex structure not only is confined to said structure, also can be set to concavo-convex rib, protruding grain or circle, quadrangle or polygonal projection, pit.In addition, this safety cap cap shell can be adopted injection mo(u)lding or multiple material forming.
The setting of this concaveconvex structure just, make safety cap cap shell when safety cap is subjected to impacting, it is the action time (promptly improving Δ t) of extending speed change greatly, reaches to reduce acceleration (a value), and then reduce active force (F value), therefore, this concaveconvex structure can promote cap shell rigidity, increase with safety cap in the contact area of cushion (EPS), reach the effect of buffering, absorb more impact energy, allow human body head be effectively protected; And under equal shock resistance required, the cap shell of employing concaveconvex structure can reduce the use amount of cap shell material, reduces the weight of safety cap, improves the comfortableness that safety cap uses.
