Embodiment

[0025] The acceleration sensor collects the acceleration of the electronic product and sends it to the information processing circuit: the digital accelerometer U3 receives control commands and sends acceleration information through the serial port composed of PIN5 and PIN6, and the chip U2 receives the acceleration from the digital accelerometer U3 through the serial port composed of PIN9 and PIN10. Chip U1 is responsible for converting the TTL serial port level of chip U2 to RS232 level. When the acceleration read by U2 is greater than or equal to the free fall acceleration, U2 sends a control signal to Q2 through PIN7, and Q2 is responsible for turning off Q1, thereby cutting off the power supply, thereby Protect the internal circuit from being burned out after the electronic product falls.

Abstract

The invention provides a power-off protection system for an electronic product drop process. The system comprises an acceleration sensor, wherein the acceleration sensor is connected with an information processing circuit; the processing information of the information processing circuit is controlled by a control circuit; and the acceleration sensor, the information processing circuit and the control circuit are all arranged in an electronic product. Compared with the prior art, the power-off protection system for the electronic product drop process can sense whether the electronic product is in a dropping state or not and cut off the power before the electronic product touches the ground so as to protect the internal circuit of the electronic product from further burnout.

Description

technical field [0001] The invention relates to a power-off protection system for an electronic product, in particular to a power-off protection system for an electronic product during a falling process, which can effectively avoid circuit burnout after the electronic product falls. Background technique [0002] During the use of electronic products, if they are used improperly, they will occasionally fall from a high place to the ground, which will cause electronic products to be bruised. However, if the electronic product is damaged when it is turned on, it is easy to cause a short circuit in the internal circuit, thereby further burning the internal electronic circuit. Most electronic products use reinforced structures to reduce product drop damage. However, thin and light electronic products, even if the structure is reinforced, will inevitably damage the internal circuit after falling. Contents of the invention [0003] The technical task of the present invention is...
