Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
As shown in Figure 1, ecto-entad of the present invention is followed successively by: shell 1, buffer body 3 and nonrigid connector 4, inner casing 2, chin belt 6.Wherein inner casing is made up of hard formation 21 and liner 22 again.Shell 1 and hard formation 21 adopt hard material to make.Buffer body 3 and shell rigidity consolidation, but can slide relative to inner casing.The concrete structure of buffer body 3 as shown in Figure 4 and Figure 5.Its structure is by fixed head 31, and pole 32, slide block 33, back-moving spring 34 and buffer spring 35 are formed.Buffer body 3 is fixed on shell by modes such as riveted joint, bolts by fixed head 31.Pole 32 is hinged with fixed head 31 and slide block 33 respectively.Every middle and lower part of root pole is connected with the middle position of fixed head by back-moving spring 34.Slide block 33 can slide in the chute 7 of hard layer top, and has buffer spring 35 to be connected (Fig. 7) between the bottom of slide block 33 and chute 7.In the present invention, the quantity of fixed head upper rack posts is at least 4, and the angle between adjacent struts is equal, is hinged on the edge of fixed head respectively.The quantity of pole is more, and the effect of damping is better.For convenience of description and illustrate, accompanying drawing has selected pole quantity to be the situation of 12.Nonrigid connector 4 and shell rigidity consolidation, but can slide relative to inner casing.The concrete structure of nonrigid connector 4 as shown in Figure 6.Its structure is made up of fixed head 41, spring 42 and slide block 43.Nonrigid connector is fixed on shell by modes such as riveted joint, bolts by fixed head 41.The hollow cylinder that spring 42 is placed in fixed head 41 and slide block 43 is inner.This spring 42 can provide radial elastic buffer.Slide block 43 can slide in the chute 6 of hard formation lower edge, and shell can be moved downward (Fig. 7) relative to inner casing.In the present invention, the quantity of nonrigid connector is at least 6.When being subject to impacting, shell moves downward, the back-moving spring 34 of buffer body and buffer spring 35 acting in conjunction, and the elastic buffer that can produce upwards is made a concerted effort.Liner 22 directly contacts with human body head, adopts the piecemeal airbag structure be communicated with or the solid construction be made up of the material such as flexible foam, sponge and fabric.An entirety is connected into by gluing between hard formation 21 and liner 22.
As shown in Figure 8, when safety cap suffers the impact 8 from top, moment shell 1 will relatively and inner casing 2 move downward.The slide block 33 of buffer body 3 and the slide block 43 of nonrigid connector 4 are also along chute slide downward.Buffer spring 35 is compressed, and back-moving spring 34 is stretched, and the two produces elastic buffer upwards jointly.Thus extend the action time of shock loading, reduce the power passing in impact process and come.Pole 32 can be distributed to passing the power of coming on the chute 7 of hard formation 21.Again because the rigidity of hard formation 21 is comparatively large, the power at chute 7 place can be distributed on larger area.This part power passed over will continue buffering by liner.Finally only having very little a part of impulsive force is delivered to head.When the active position of shock loading 8 has a certain deviation relative to center position, shell also can produce the trend of rotation while having downward movement tendency.At this moment the radial direction at safety cap is stretched or is compressed by nonrigid connector 4, and namely spring 42 is stretched or compresses.The making a concerted effort of spring 42 produce resistance torque relative to the active position of shock loading 8, hinder the rotation of shell.So just extend the action time of shock loading, reduce the turning moment being delivered to head.
