Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as Figure 1-7 Shown: a multi-directional shockproof 3D printed helmet energy-absorbing buffer layer, the 3D printed helmet energy-absorbing buffer layer is fixed on the inner side of the helmet shell;

[0023] The energy-absorbing cushioning layer of the 3D printed helmet is in the shape of a head as a whole, and consists of five split parts: a front split part 1, a rear split part 3, a left split part 4, a right split part 5 and an upper split part 2 put together;

[0024] The five slice parts all include an upper unit 6, a lower unit 7, a through hole 9 and several through rods 8, and the slice parts pass through the through rod holes 9 on the upper unit 6 and the lower unit 7 through the through rods 8 connected;

[0025] The opening cross-sectional area of ​​the through-rod hole 9 is larger than the cross-sectional area of ​...

Abstract

The invention discloses a multidirectional shockproof 3D printing helmet energy absorption buffer layer. The 3D printing helmet energy absorption buffer layer is fixed to the inner side of a helmet shell. The 3D printing helmet energy absorption buffer layer is integrally in a head shape and is formed by splicing a front fragmentation part, a rear fragmentation part, a left fragmentation part, a right fragmentation part and an upper fragmentation part. Each fragmentation part comprises an upper layer unit, a lower layer unit, a through rod hole and a plurality of through rods, and the fragmentation parts are formed by penetrating through the through rod holes in the upper layer units and the lower layer units through the through rods in a connected mode. According to the invention, energycan be fully absorbed through twice crumpling deformation of the buffer layer, and the impact force acting time is delayed; in addition, damage to the head and the spine caused by rotating force can be reduced through staggered sliding between the upper buffer layer unit and the lower buffer layer unit, and in addition, the buffer layer has the advantages of being comfortable to wear, good in ventilation, light in weight, capable of being used for personalized customization and the like.

Description

technical field [0001] The invention belongs to the technical field of helmets, in particular to a multi-directional shockproof 3D printed helmet energy-absorbing buffer layer. Background technique [0002] The function of the helmet is to reduce the damage to the head due to inertia and collision in the event of an accident. A traditional helmet consists of a rigid shell, a helmet lining, and a suspension system. The helmet lining, as the most important energy dissipation component inside the helmet, is the design focus of the helmet's impact resistance. [0003] When the head is subjected to external impact, the impact force can be decomposed into vertical impact force and shear impact force. The vertical impact force causes the translational acceleration of the head, causing injuries such as skull fractures, and the shear impact force causes the rotational acceleration of the head. , resulting in spinal torsion and other injuries. Traditional helmet linings are often ma...
