Problems solved by technology

[0004] At present, most of the existing protective materials and structures are static structures, and their performance characteristics cannot be adjusted according to needs.
Typical materials such as Kevlar, glass fiber, etc., although they have high strength, are too soft in some application scenarios and need to be coated with resin materials to form composite materials

Embodiment 1

[0023] figure 1 It is a schematic diagram of the layered structure of the present invention. Among them, 1 is a flexible wrapping layer, 2 is a hollow storage array, 3 is a liquid metal phase change filling material, 4 is a temperature control fluid, 5 is a liquid pump, 6 is a fluid pipeline, 7 is a refrigeration module, 8 is a control circuit, and 9 is a heating module. The liquid metal phase change filling material 3 is filled inside the hollow storage array 2 . The hollow storage array 2 is an array with a cavity structure made of flexible material such as silicone or rubber. The hollow storage array 2 is attached to the flexible wrapping layer 1. When the liquid metal phase-change filling material 3 is in a liquid state, the entire hollow storage array 2 is also in a flexible state. Under the action of external force, the flexible wrapping layer 1 and the hollow storage array 2 will be deformation, such as image 3 shown.

Abstract

The invention provides a flexible changeable protection structure. The structure comprises a flexible wrapping layer, a hollow storage array, a liquid-state metal phase change filling material, temperature control fluid, a liquid pump, a fluid pipeline, a refrigeration module, a heating module and a control circuit. Through the refrigeration module and the heating module, the temperature control fluid can be cooled or heated, the liquid pump is used for enabling the temperature control fluid to flow in the fluid pipeline, the liquid-state metal phase change filling material is in the solid phase or liquid phase state through temperature, and therefore the hardness of the flexible changeable protection structure can be changed, and switching between flexibility and rigidity can be achieved. The structure can be used for fields of police equipment, industrial production protection, military equipment and the like.

Description

technical field [0001] The invention belongs to the technical field of safety protection, in particular to a flexible and variable protection structure. Background technique [0002] Liquid metal is a metal material with a melting point below 300°C, which exhibits solid metal properties at low temperatures and liquid form at normal or high temperatures. Liquid metals are usually dominated by gallium metal and its alloys, including gallium-indium alloys and gallium-indium-tin alloys. It has good electrical and thermal conductivity, metallic luster, good fluidity and surface tension in a liquid state. Liquid metal has certain wettability, and liquid metal ink can be used to make flexible mechanical sensors, and it can also be combined with its conductivity and flow properties to make electromagnetic pumps that can be directly driven by electricity. [0003] In military, public security, and industrial production, security protection is a very important requirement. Generall...
