Abstract
The invention discloses a product drop impact-resisting protecting method. By collecting data of a micro mechanical gyroscope and an accelerated speed sensitive combination external component, the state of a product in a drop process is calculated in real time, and the dangerousness grade of the product is judged timely. When the dangerousness grade of the product exceeds the grade that the product is damaged but the function of the product is not affected, a product drop impact-resisting system activates an airflow jet device to change the motion state of the product. When the dangerousness grade of the product exceeds the grade that the product is damaged and the function of the product is affected, the product drop impact-resisting system activates a safety airbag, and collision damage to the product is reduced through the safety airbag. The product drop impact-resisting protecting method effectively solves the problem that the interior of the product is damaged when the product suffers drop impact. The product drop impact-resisting protecting method achieves use convenience, low price of the system, convenient operation and convenient control.
