Description

Technical Field

[0001] The invention belongs to the technical field of protective equipment, and in particular relates to a freely movable helmet load transfer device and a working method thereof. Background Art

[0002] Helmets, as core head protection equipment, play a crucial role in protecting the user's head. As the protection level and intelligence level of protective helmets increase, their weight also increases significantly. For example, some smart helmets, after integrating intelligent modules, can weigh up to 1.5-2kg. The long-term load of the helmet is concentrated on the user's head and cervical spine, leading to excessive cervical spine load and accumulated muscle fatigue. This can cause headaches, shoulder and neck strain, and even chronic injuries during long missions, seriously damaging the user's health and affecting work efficiency and safety.

[0003] To solve the load problem, currently commonly used technologies mainly adopt two types of solutions. One is to disperse local pressure by optimizing the lining material of the helmet. This solution can make the head bear the force evenly, but it cannot change the direction of the force. The cervical spine still needs to bear most of the weight of the helmet; the other is to add a metal / plastic bracket under the helmet to connect the shoulders. Although this solution can transfer part of the load, it sacrifices the flexibility of the head. The freedom of movement of the head is severely restricted, making it difficult to adapt to dynamic sports scenes. Summary of the Invention

[0004] The purpose of the present invention is to provide an efficient and freely movable helmet load transfer device and its working method, which can transfer the weight of the helmet to the shoulders through a mechanical path while ensuring the freedom of movement of the head, thereby reducing the load on the neck and head.

[0005] To achieve the purpose of the present invention, on the one hand, the present invention provides a freely movable helmet load transfer device, comprising a head connection module, a load-bearing rod, a middle connection piece, an elastic rod, a ball joint, a quick-release buckle, and a platform support piece;

[0006] The head connection module is used to provide an upward pulling force for the helmet, reduce the load weight of the wearer, and provide a degree of freedom of left and right rotation;

[0007] The load-bearing rod and the elastic rod are used to form the main force transmission path of the device, and through synergistic action, the helmet load is evenly transmitted downward to the two shoulders;

[0008] The middle connecting piece is used to fix the load-bearing rod and the elastic rod, and cooperates with the load-bearing rod to quickly adjust the height to suit different people;

[0009] The ball joint is used to provide the freedom of pitching forward and backward and rotating left and right, allowing the head to move freely;

[0010] The quick-release buckle is installed on the platform support and is used to quickly separate the device from the platform support to complete the quick release and quick installation of the helmet;

[0011] The platform support is used to evenly transfer the load transferred from the head to the two shoulders.

[0012] The head connection module is connected to one end of the load-bearing rod, the other end of the load-bearing rod is connected to the connection hole of the middle connecting piece, the connection hole of the middle connecting piece is connected to the upper end connection hole of the elastic rod, the upper end connection hole of the elastic rod is connected to the ball of the ball joint, the ball socket of the ball joint is connected to the quick-release male buckle of the quick-release buckle, the quick-release female buckle of the quick-release buckle is connected to the quick-release buckle connection hole of the platform support, and the webbing hole of the platform support is connected to the fixed end on the user's shoulder.

[0013] On the other hand, the present invention also provides a working method of a freely movable helmet load transfer device, wherein the platform support is connected to the exoskeleton on the shoulder through a webbing, and the quick-release male buckle on the elastic rod is locked to the quick-release female buckle of the platform support through a magnetic lock to realize the connection between the load transfer device and the shoulder; when the load transfer device is working, the user wears a helmet, connects the head connection module of the load transfer device to the helmet, and the platform support is connected to the shoulder, and the load-bearing rod is adjusted to a comfortable height. The load-bearing rod gives the helmet an upward pulling force, which is then transmitted downward through the deformation of the elastic rod, so that the weight of the helmet can be evenly transferred to both shoulders, thereby achieving the effect of load transfer; when the user's head rotates left and right, it can drive the bearing part and the ball joint of the head connection module to rotate together, and the user's head pitches back and forth, which can drive the elastic rod to deform downward, and at the same time the ball joint rotates together, thereby realizing flexible movement of the head.

[0014] Compared with the prior art, the present invention has significant improvements in that: the present invention effectively reduces the head load, and the rotatable bearing of the head and the movable ball joint of the shoulder allow the head to move flexibly and perform dynamic movements.
