Intrinsic safety type direct current power supply device suitable for wearing

Abstract

The present invention discloses an intrinsic safety type direct current power supply device suitable for wearing. The device comprises: a battery module configured to supply electric quantity and a complementary electric quantity; a power management protection module configured to control charge and discharge control of the battery module to output a usage voltage of preventing the battery modulefrom over-charge or over-discharge and stabilizing an output voltage of the battery module to an external device; and an output module configured to safely output the voltage stably output by the power management protection module to the external device for power supply. The intrinsic safety type direct current power supply device special for the coal mine industry is achieved.

Description

technical field [0001] The invention relates to an intrinsically safe device, in particular to an intrinsically safe DC power supply device suitable for wearing. Background technique [0002] With the widespread application of portable electronic devices (such as smart phones, tablet computers, etc.), due to the technical bottleneck of the battery of portable electronic devices, the battery life is very limited, and the power bank itself has a power storage unit that can directly charge portable electronic devices. , and the charging treasure is easy to carry, therefore, the use of charging treasure is becoming more and more extensive. [0003] figure 1 It is a schematic structural diagram of an existing charging treasure. See figure 1 , the existing power bank 10 includes a power management chip 12 and a battery 14, the power management chip 12 is provided with a boost circuit 122 and a charging circuit 123, and the power management chip 12 can be connected via a USB (Un...

AI Technical Summary

Problems solved by technology

[0006] 1. As a DC power supply device, the conventional power bank is a non-intrinsically safe device and does not have waterproof and explosion-proof capabilities;

[0007] 2. The USB current output standard provided is 5v, which does not have the special voltage output capability for mining equipment, and is not suitable for mine use;

[0008] 3. It is unable to provide the ability to increase battery capacity in parallel, which is not conducive to the demand for battery life in special operations;

[0009] 4. Unable to provide waterproof and explosion-proof interfaces and intrinsically safe power lines and data lines;

[0010] 5. Lack of remote display function for charging or remaining power
