| my country is a country with frequent natural disasters,such as earthquakes,landslides,and landslides.Taking earthquakes as an example,in the 2020 National Conference of Earthquake Directors,the "Seismic Annual Report 2019" released by the China Earthquake Administration showed that there were 30 earthquakes of magnitude5 and above in China in 2019,and natural disasters such as earthquakes occurred frequently and were harmful The degree is deep,causing many casualties.There are a large number of official and private rescue organizations and rescue personnel in the country.However,at this stage,the protective function clothing of rescuers is relatively simple.There is still a lot of research space to improve the safety guarantee coefficient of rescuers.In the communication with the staff responsible for clothing procurement of the largest private rescue organization in China,I learned that in the current situation of disaster relief,only the helmets of the equipment worn by the rescuers have a certain protective effect,and most of the clothes worn only have rain protection,tear resistance,The basic functions such as the iconic color and the reflective warning of the fabric have no protective effect when they encounter fatal injuries such as impact and extrusion.At present,the intelligent functional research in the field of textiles and garments at home and abroad has become a trend."Made in China 2025" and "Industry 4.0" have further enhanced the depth of intelligent clothing research in China.However,protective clothing and construction workers for natural disaster rescuers The research of protective functional clothing against squeeze and impact needs a long time to improve.This subject is aimed at this situation,based on the performance of flexible pressure sensors,from the perspective of protective clothing protection functionality and dressing physiological comfort,design and research of airbag-type passive protective device functional clothing,with a view to alleviating the wearing object caused by squeeze impact injury Life safety threats.The research of this topic mainly includes the following aspects:First,it elaborated the research background of this subject and data on earthquakes,landslides,construction accidents,etc.,clarified the research content,and highlightedthe research significance and innovation direction.According to the different fields of use,it categorizes and summarizes the existing products in the airbag protective clothing market at home and abroad.Second,introduce the flexible pressure sensor,explain the relationship in a progressive manner of sensor,pressure sensor,flexible pressure sensor,classify and introduce their application status and development trend.Starting from the components of the flexible pressure sensor,the material performance of each part is analyzed,and the material combination of the flexible pressure sensor that is most suitable for this subject is summarized.Third,analyze the influencing factors of airbag design from the aspects of airbag material and manufacturing process.Fourth,through the analysis of the wearing object,the double-layer airbag structure is designed to achieve the protection function of the squeeze on the fatal parts of the body.In the structural design of the double-layer airbag,the first layer of airbag is deployed according to the distribution of sweating in the male body,which is used as the link medium of the flexible sensor.The structure of the second layer of airbags is structured according to the injury type of 96 collapse accidents and squeeze injury cases.The structural design makes the airbags vulnerable to the body 's neck,shoulders,spine,ribs,pelvis,etc.Extrusion impact damage parts play a good protective role.Fifth,other design of airbag protective functional clothing system,including the fabric performance requirements and structural design of the liner,the fabric performance requirements and structural design of the outer jacket,and the selection of types of compressed gas cylinders. |
