Multi-functional digital display alarm emergency power supply with safety warning

Abstract

The invention provides a multi-functional digital display alarm emergency power supply with safety warning. The power supply comprises a power supply main body, a high magnification cell and an MCU control circuit board. A magnetic suction device which can fixedly absorb a product and metal is arranged on the back or front lower end face of the casing body of the power supply main body. A digital display which displays power supply in percentage, a red and blue light strobe alarm light and an alarm sign are arranged on the front of the casing body. A flashlight / SOS / burst flash LED light, a 5V power output interface and a 12V power automobile ignition output interface are arranged on one side of the side wall of the casing body. A switch button which is used for power display, flashlight, burst flash, SOS and red and blue light strobe alarm light work mode switching, a Mic USB power input interface and a solidified electronic whistle are arranged on the other side of the side wall of the casing body. The power supply provided by the invention can be used for 12V automobile emergency ignition start and used as the supplement power supply of most of 5V police electronic equipment, has the functions of disaster relief field police work lighting and red and blue light safety warning, is portable, practical and convenient, and is practically convenient for people and police.

Description

technical field [0001] The invention belongs to the technical field of electric energy storage system of power supply or power distribution circuit device, and specifically relates to a multifunctional digital display police emergency power supply with safety warning, which can be used for emergency ignition start of 12V automobiles and supplementary power supply of most 5V police electronic equipment .

[0002] At present, the design of police emergency mobile power supply products is mainly to realize the design of power supply, lighting, positioning, and solar charging functions. However, in the face of emergency situations such as law enforcement vehicles going out unexpectedly and citizens' vehicles unexpectedly turning off, it seems that helpless

In addition, the emergency starting power supply that can realize the emergency start of the car is complementary to the auxiliary police functions related to police duty and law enforcement, such as flashlight, SOS, strobe LED lighting, red and blue strobe lights, and the functional design of the help method is not enough. Comprehensive defects; in addition, any of the above-mentioned portable mobile devices need to be held or supported by the platform to achieve long-term power supply. The mobile power supply is placed horizontally or erected somewhere. How to prevent the accidental fall of the high-rate batteries that are not to be dropped or shaken from the support platform has not seen an effective solution so far, so the following improvements are proposed
