Device capable of being used at any angles but powering off when being suffered from impact of external force

Abstract

The invention discloses a device capable of being used at any angles but powering off when being suffered from impact of external force. The device comprises a PCBA board base material, an impact switch, a single chip microcomputer, a silicon control and necessary electrical components, wherein the impact switch comprises a vibration sensor, a wireless communication module, a switch control moduleand a power switch, the single chip microcomputer is used as a core controller, is connected with the impact switch, installed on a PCBA board, and used for controlling each module; the silicon control is used for controlling the product power, and the necessary electrical components comprise components such as electrical inductances. A threshold of the external force is set through the single chip microcomputer, and when the external force on the device exceeds the set threshold, the device powers off automatically. According to the device capable of being used at any angles but powering offwhen being suffered from the impact of the external force, the defects caused by angle limitation during use of original falling devices are overcome, automatic power off is achieved when the deviceis subjected to the excessive external force, and safety performance is higher; and a method combining software and hardware is adopted, the sensitivity of the device is improved, the needs of marketcustomers are met, and the requirements of corresponding safety specifications and laws and regulations are met.

Description

technical field [0001] The invention relates to an intelligent power-off device in a PCBA board, in particular to a device that can be used at any angle but is powered off by external force impact. Background technique [0002] With the continuous development of communication technology and micro-sensor technology and the continuous progress of the information society, the development of convenient and reliable intelligent power-off devices has become a new direction. [0003] In the prior art, the intelligent power-off and falling device in the PCBA board has always stayed at the level controlled by the angle. Generally, the inclination angle of the ordinary falling device is 45 degrees, that is, the power is cut off at an angle of 45 degrees. If the customer adjusts the angle, However, due to the limitation of the 45-degree angle, the product cannot work normally, and if the product is tilted 45 degrees for other human reasons under normal circumstances, the power will be ...

[0003] In the prior art, the intelligent power-off and falling device in the PCBA board has always stayed at the level controlled by the angle. Generally, the inclination angle of the ordinary falling device is 45 degrees, that is, the power is cut off at an angle of 45 degrees. If the customer adjusts the angle, However, due to the limitation of the 45-degree angle, the product cannot work normally, and if the product is tilted by 45 degrees for other human reasons under normal circumstances, the power will be cut off, which is very inconvenient
