Electroencephalogram safety helmet lining

Abstract

The invention provides an electroencephalogram safety helmet lining. The lining comprises a helmet lining body and an elastic boss, an electroencephalogram electrode used for making contact with a human body is fixedly arranged on the boss, and the boss is fixed to the helmet lining body through an elastic accessory or an inflatable airbag; and the boss comprises a groove part and a supporting wall, the groove part is used for fixedly installing the electroencephalogram electrode, the interior of the supporting wall is of a hollow structure, one end of the supporting wall is used for being connected with the groove part, and the other end of the supporting wall is fixedly installed on the elastic accessory or the inflatable air bag. According to the electroencephalogram safety helmet lining, through the arrangement of the elastic accessory or the inflatable air bag, the comfort of a wearer can be guaranteed, meanwhile, the elasticity can be recovered, a tiny gap between the helmet lining and the forehead is effectively avoided, and electroencephalogram collection and analysis are not affected.

Description

technical field [0001] The invention relates to a safety helmet, in particular to an EEG safety helmet lining installed on the safety helmet. Background technique [0002] The existing EEG safety helmet is to directly fix the EEG electrodes on the existing cap liner, and detect whether the safety helmet is worn by means of EEG signal collection. When wearing a safety helmet, it is impossible to screw it very tightly. Due to the action of gravity, there will be a small gap between the helmet lining of the prior art and the forehead when people are moving, especially when the head is bowed. This gap will affect the collection and analysis of EEG , The contact between the human head and the EEG electrodes is not good, resulting in poor signal, which makes the basic functions of the equipment impossible to realize. At the same time, the contact feeling between the existing electrodes and the human body is not good, causing long-term wearing discomfort; when working dynamically,...
