Abstract
The invention relates to application of a particle damping technology in daily necessities. A safety helmet based on a particle damping structure comprises a shell, a buffer layer, an inner shell, a damping layer and a lining layer in sequence from outside to inside, wherein the damping layer is composed of multiple damping cavities, and each cavity is filled with particle damping. According to the safety helmet based on the particle damping structure, on one hand, penetration caused by external force can be prevented; on the other hand, buffering is conducted on the force, and the energy brought by impacts can be consumed through resonance. The safety helmet based on the particle damping structure has the advantages of being simple in design and good in shock resistance.
Description
Technical field
The present invention relates to the application of particle damping in daily necessities, particularly relate to a kind of safety cap based on particle damping structure.
Background technology
Traditional safety cap shock absorption principle is: the gap having 25 ~ 50mm between cap shell and hat lining, and when object hits safety cap, cap shell does not directly have influence on crown portion because of stress deformation; Cap shell is oval or hemispherical, smooth surface, and when object falls on cap shell, object can not stop landing immediately; And the holding capacity that cap shell overwhelms a little is transmitted towards periphery, by the Li Keda more than 2/3 that hat lining buffering reduces, remaining power passes to the cranium of people through the whole area of hat lining, so just impetus is become focusing surface, thus it is concentrated to avoid impulsive force certain some stress on cap shell, decreases unit are stressed.
The cap shell of conventional security cap makes with rigid plastics, if when running into sharp-pointed pendant thing, will be pierced, thus threaten the safety of people when decline kinetic energy reaches certain value cap shell.
Therefore, how to design the better safety cap of a security performance and become one of the research and development problem in future.
Summary of the invention
In view of this, we provide a kind of safety cap based on particle damping structure, there is better security performance.
Safety cap based on particle damping structure of the present invention, comprises from outside to inside successively: shell, cushion, inner casing, damping layer and inner liner; Wherein, described damping layer is made up of multiple damper housing, and each cavity is filled with particle damping, for resonating to consume the energy that shock brings.
Preferably, described particle damping, its surface characteristic comprises: surface nontrentment, rough surface and surface finish process.
Preferably, described particle damping, its geometry comprises spherical.
Preferably, described particle damping, its diameter range is between 1-12mm, and the density range of particle is at 1-20g/m
3between.
Preferably, shell and inner casing all adopt hard material.
Preferably, described cushion is made up of spring or air bag, is highly 20mm-30mm.
Preferably, also chin strap is comprised.
Consume by friction and percussion between the molecule of filling in constrained space the energy that object falls on cap shell in the present invention, thus decrease the active force being assigned to head, ensure within the scope of its Biological Strength that can bear at people's cervical vertebra, and must safety cap be two-layer owing to forming enclosure space, also prevent sharp-pointed pendant thing to pierce through the danger generation of cap shell.
Accompanying drawing explanation
Fig. 1 is the generalized section based on the safety cap of particle damping structure in the present invention.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage more clear, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, be depicted as the generalized section based on the safety cap of particle damping structure in the present invention.The described safety cap based on particle damping structure comprises from outside to inside successively: shell 1, cushion 2, inner casing 3, damping layer 4 and inner liner 5.
Described safety cap adopts duplex shell structure, and namely shell 1 and inner casing 3, all adopting hard material, being penetrated by safety cap for preventing external force.
Between shell 1 and inner casing 3, be provided with the cushion 2 between 20mm-30mm, described cushion is made up of spring, air bag or special padded coaming etc., from the angle of mechanics or material, provides elastic buffer.
Damping layer, between about 10-20mm, is made up of multiple damper housing, is at least filled with the particle damping of 10%-30% in each cavity, for being consumed the energy clashing into and bring by resonance.
Described particle damping, its surface characteristic comprises surface nontrentment, rough surface and surface finish process, and the geometry of particle comprises spherical, and diameter range is between 1-12mm, and the density range of particle is at 1-12mm.
The embodiment of the common particle damping of table 1
More traditional humanized of the shock absorption principle of particle damping safety cap, but due to many one deck shells, particle will be loaded in addition, its weight must be made greatly to increase, wearer is born a heavy burden increase, head flexibility ratio reduces, and considers cost of manufacture simultaneously, so the particle loaded should be selected more cheap a little compared with lightweight, price.
It should be noted that, volume, the shape of each point of cavity are different, and the filling rate of the particle damping of its best configuration is also different, and object is in order to the resonant frequency of damping and lathe can be made to reach optimum Match degree.Damping structure of the present invention, when vibrating, noise and when causing cycle, aperiodic oscillation, there is the freely-movable that similar electronics is excited in the particle damping be enclosed in damper housing, mutual shock, frictional dissipation is macro-energy comparatively, for absorbing and consume the vibrational energy of external force, actually increases the damping of system, vibration velocity is decayed rapidly, or during resonance, amplitude diminish.
Described inner liner 5, adopts soft material to form, better wraps up head, enlarge active surface, and mainly it can distribute pendant thing decline kinetic energy to whole head, and cooperation chin strap 6 can be fixed cap and is not easy landing.
The Biological Strength that the cervical vertebra of people bears is limited, the kinetic energy that pendant thing declines only is assigned to whole head by hat lining by conventional security cap completely, there is no the stage that energy reduces, and consume by friction and percussion between the molecule of filling in constrained space the energy that object falls on cap shell based on the Novel safety cap of particle damping, thus decrease the active force being assigned to head, ensure within the scope of its Biological Strength that can bear at people's cervical vertebra, and must safety cap be two-layer owing to forming enclosure space, also prevent sharp-pointed pendant thing to pierce through the danger generation of cap shell.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
