Description

{Thermostatic temperature control and shock absorbing IoT helmets}

The present invention relates to an IoT hard hat capable of temperature control and shock absorption using a thermoelectric element, and more particularly, the inner skin of the hard hat forms a predetermined distance from the wearer's wearing part, so that air circulation is possible inside the work cap, and the outer skin of the work cap It is possible to efficiently distribute external shock by composing a hexagonal cell assembly, and it relates to an IoT hard hat capable of temperature control and shock absorption using a thermoelectric element that can control internal heat through cooling/heating due to the control of the thermoelectric element. .

Electronic cooling using thermoelectric conversion materials is a semiconductor cooling method that uses the Peltier effect, in which one end heats up and the other end absorbs heat when a direct current is applied between both ends of the material. It is friendly, has a simple structure and high reliability, and there is no noise and vibration because there are no mechanical moving parts, and it has the advantages of selectively cooling a local part of the circuit. Accordingly, in recent years, in response to the trend of miniaturization, high power, and high-density mounting of electronic components, the electronic cooling method is applied to local cooling of various electronic devices and IC products such as infrared sensor, laserdiode, and focal plate cooling of CCD devices in advanced countries. In addition to scientific measuring equipment and medical equipment, the scope of application is gradually expanding in the home appliance industry such as refrigerators, air conditioners and heat exchangers.

In Korea, we are already working in various home appliances fields such as water purifier using electronic cooling method, kimchi-dok, cold and hot storage for automobiles, and towel maker, as well as electronic parts such as computer CPU chip cooler, laser diode modulator for optical communication, and constant temperature control of ink jet printer head. The electronic cooling method is applied to mobile communication unmanned base stations and electronic component cabinets for communication.

Specifically, the thermoelectric module (Thermoelectric module) is used in the form of a module in which n, p type thermoelectric semiconductors are electrically connected in series and thermally in parallel in a ð-type. When DC current flows here, a temperature difference occurs on both sides of the module due to the thermoelectric effect, and power generation occurs at the same time. In general, a thermoelectric module refers to a solid state heat pump that uses a cooling effect caused by the Peltier phenomenon.

The thermoelectric phenomenon is a phenomenon in which the flow of heat and electricity is related and appears together, and it appears as three effects: the Seebeck effect, the Peltier effect, and the Thomson effect.

A worker wearing a conventional hemispherical work hat cannot protect the worker from a poor work environment due to the structure of the work cap that is not ventilated and cannot control heat, leading to human injury.

In addition, the thermoelectric method was difficult to apply to the helmet due to its volume and weight.

Therefore, to solve the problems of the prior art, the inner skin of the hard hat forms a predetermined distance from the wearing part of the worker, so that air can be circulated inside the working cap, and the outer shock of the working cap is composed of an assembly of hexagonal cells. It is an urgent situation to develop technology for an IoT safety helmet that can control temperature and absorb shock using a thermoelectric element that can efficiently disperse the temperature and can control internal heat through cooling/heating due to the control of the thermoelectric element.
