Airbag helmet and special helmet accelerometer thereof

Abstract

The invention discloses an airbag helmet and a special helmet accelerometer thereof. When a driver encounters a dangerous situation and the head collides to the ground in the riding process, namely afirst linear elastic block or a second linear elastic block is fallen down to the ground and can produce acceleration collision under the attack, while a piezoelectric energy conversion block is in electric connection with an airbag on the airbag helmet through a control circuit so as to convert impact mechanical energy to voltage signals through the piezoelectric energy conversion block to supplyelectricity for opening of the airbag when the driver encounters the dangerous situation and the helmet falls down to the ground by collision and impact, and the airbag can be opened rapidly to protect the head of the driver; meanwhile, a self-contained power is not needed, so that safety protection can be effectively achieved, while the weight of the helmet is reduced; and in addition, the larger the acceleration of the airbag helmet is, the larger the voltages generated by the piezoelectric energy conversion block are, and at the same time, a larger voltage can be generated under small acceleration in order to ensure the smooth opening of the airbag and triggering reliability.

Description

technical field [0001] The invention relates to the technical field of airbag helmets, in particular to an airbag helmet and a special helmet accelerometer thereof. Background technique [0002] Traffic accidents occur frequently, and the fatality rate and injury rate remain high. Two-wheeled vehicles such as motorcycles, bicycles, and electric vehicles are widely accepted by the public with their advantages of portability and low cost, and become one of the necessary means of transportation for families. However, because two-wheeled vehicles have poor stability, unstable speed, and lack of corresponding protection facilities, the risk of driving this type of vehicle is extremely high. Therefore how to increase effective protection for two-wheeled vehicles is particularly important. The current protective measures are mainly to wear helmets to protect the fragile head organs and tissues of the human body. The helmets on the market are similar, and the main focus is on the...

Problems solved by technology

As for the helmet, due to the limitations of the structure of the helmet, if the airbag is designed with a power supply, it not only needs to maintain the power supply from time to time, but also is relatively heavy. Once the maintenance is forgotten or there is a problem with the power supply during use, the airbag will not be triggered. open and other issues, affecting security
