Embodiment Construction

[0010] Such as figure 1 The schematic diagram of the structure of the explosion-proof monitoring device for smart phone batteries is shown, including thermal conductive adhesive 1 , several patch piezoelectric sensors 2 , two patch temperature sensors 3 , connecting cables 4 and a microprocessor 5 . The microprocessor 5 is respectively connected to the piezoelectric sensor 2 and the temperature sensor 3 via the connection cable 4 . Wherein: the piezoelectric sensor 2 can monitor the volume change of the battery in real time, and send the information to the microprocessor 5 for data processing. The temperature sensor 3 can monitor the temperature data of the battery in real time, and send the temperature data to the microprocessor 5 .

[0011] When the data sent by the patch piezoelectric sensor 2 to the microprocessor exceeds the preset value, and the temperature data sent by the patch temperature sensor 3 to the microprocessor 5 exceeds the preset temperature, the microproce...

Abstract

The invention relates to an anti-explosion monitoring device for a smartphone battery. The anti-explosion monitoring device comprises heat-conduction fixing glue, a plurality of surface-mounted piezoelectric sensors, two surface-mounted temperature sensors and a microprocessor, wherein the heat-conduction fixing glue is dead against to the smartphone battery; the size of the heat-conduction fixing glue is matched with the size of the battery; the surface-mounted piezoelectric sensors and the surface-mounted temperature sensors are positioned between the heat-conduction fixing glue and the smartphone battery; the piezoelectric sensors are used for monitoring the size change of the battery in real time; the temperature sensors are used for monitoring temperature data of the battery; and data acquired by the piezoelectric sensors and the temperature sensors are transmitted to the microprocessor. The device has a function of making an early warning about the potential safety hazard of the battery in time, can be mounted inside a smartphone perfectly, can be directly charged through a power supply inside the smartphone, and has an active heat-dissipation function specific to battery released heat.

Description

technical field [0001] The invention relates to a monitoring device, in particular to an explosion-proof monitoring device for smart phone batteries. Background technique [0002] With the development of modern technology, the penetration rate of smartphones has increased by leaps and bounds. At the same time, there are more and more models to choose from on the market. Various functions, larger and larger battery capacity and battery life have undoubtedly become It is one of the main criteria for people to choose mobile phones. At present, lithium-ion batteries are commonly used in mobile phones. With the increase in the frequency and time of use of smartphones, the anode and cathode separators of the battery are partially thinned, and short circuits are prone to occur when the insulating tape does not completely cover the plate coating, resulting in abnormal heating of the battery. , In extreme cases, spontaneous combustion or explosion may occur, and the use of mobile ph...
