Embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
A kind of vapor-permeable type helmet shell of the present utility model, its structure is as shown in figure 1, outside including the helmet in half elliptic
Shell body 1, helmet shell body 1 includes being located at the full cladding area 2 at the top of helmet shell body 1 and positioned at helmet shell body 1
The anchor ring ventilating area 3 of side, as shown in Fig. 2 anchor ring ventilating area 3 offers some air-vents 4, the central shaft of air-vent 4 with thoroughly
The angle of the surface normal of helmet shell body 1 where the center of stomata 4 is 15 °~45 °.
As shown in figure 3, the ear region that helmet shell body 1 is located at both sides offers multiple sound transmission apertures 5, sound transmission aperture 5 exists
The ear region that helmet shell body 1 is located at both sides is distributed in a ring.
The aperture of sound transmission aperture 5 is 2mm~5mm.
Helmet shell body 1 is made up of titanium alloy.
Air-vent 4 is diamond hole or slotted eye.
As shown in figure 4, the diamond hole length of side is 2mm.
As shown in figure 5, the major axis of slotted eye is 3.5mm, short axle is 1.5mm.
Anchor ring ventilating area 3 includes multiple ventilative aperture areas 31 and multiple entity areas 32, and breathe freely aperture area 31 and entity area 32
It is arranged at intervals, ventilative aperture area 31 is set to sector, the symmetrical distribution on helmet shell body 1 of aperture area 31 of breathing freely,
Angle is 15 °~18 ° between each ventilative aperture area, between two ventilative aperture areas 31 of the junction of helmet shell body 1 or so
Angle is 30 ° or 45 °, and the fan angle of each ventilative aperture area 31 is 20~45 °.
When making a kind of vapor-permeable type helmet shell of the present utility model, according to normal human's head shape design helmet shell
Contour shape, it is determined that design size on the basis of shape, design size needs to be thought of as later stage helmet liner and suspension arrangement
Installation reserve space.
Helmet shell entirety gabarit is elliposoidal, and ellipsoid major axis radius is 273mm, ellipsoid minor axis radius 247mm, outside the helmet
Shell depth 208mm, helmet shell thickness is 2.0mm.
The division of helmet shell cladding area and ventilating area is determined, on the basis of helmet top apex, 30mm is offset downward true
Determine cross section, be full cladding area 2 by the region division between at the top of the cross section and the helmet.
The full cladding area 2 of helmet shell body 1, remaining region is anchor ring ventilating area 3, the upper selection 6 in anchor ring ventilating area 3
Individual sector region is as ventilative aperture area 31, and the symmetrical distribution on helmet shell body 1 of aperture area 31 of breathing freely is each ventilative
Angle is 15 °~18 ° between aperture area, and angle is between two ventilative aperture areas 31 of the junction of helmet shell body 1 or so
30 ° or 45 °, the fan angle of each ventilative aperture area 31 is 20~45 °, close to the front portion of helmet shell body 1 i.e. close to face
The fan angle of the ventilative aperture area 31 in portion region takes smaller value, and the rear portion of nearly helmet shell body 1 is close to hindbrain region
The rear portion of helmet shell body 1 takes higher value.
The full cladding area 2 on the top of helmet shell body 1 is entity clad structure, and this subregion primary protection is to human body
Damage the surface of maximum and its falling object of radiating surface.
Anchor ring ventilating area 3 is offered outside some air-vents 4, the helmet where the central shaft of air-vent 4 and the center of air-vent 4
The angle of the surface normal of shell body 1 is 15 °~45 °, and the design of angling hole makes outside any direction perpendicular to the block of helmet curved surface
Shape splash, it is impossible to directly through the air-vent 4 opened, while helmet safety is ensured, greatly improve the helmet
Gas permeability, can so increase the comfortableness of wearer.
In the two sides ear region of helmet shell body 1, a number of permeability sound transmission aperture 5 is provided with, as shown in fig. 6,
Sound transmission aperture 5 is circumferentially distributed along helmet surface, and aperture is about 2~5mm, and the central area for pressing close to ear is entity clad structure, this
One design makes external sound wave pass through the sound transmission aperture 5 that annulus is distributed, and clearly incoming wearer ear, in ear center, then adds
Plus entity protection, prevent splash from being damaged to ear.
There is continuous entity area 32 between the anchor ring ventilating area 3 of whole helmet shell body 1, each region breathable microporous, this
A little regions can give over to the location and installation position of later stage lining assembling, while the overall distribution state-visibility of entity area makees a kind of add
Strengthening tendons structure, it is ensured that the full cladding area 2 of overall helmet shell body 1 and the continuity intensity of anchor ring ventilating area 3.The whole helmet
Material can use titanium alloy, steel, engineering plastics etc., preferably titanium alloy, the more traditional steel of titanium alloy can loss of weight about 40%~
45%, strength level maintains an equal level, thus total has higher specific strength and specific stiffness.
