Problems solved by technology

[0003] Traditional electronic locks using lithium batteries use 8.4V power supply and cannot use 3.7V power supply, because the access voltage of 3.7V lithium battery power supply is lower than the voltage of dry batteries, so lithium battery power supply cannot work

Abstract

The invention provides an electronic lock wide voltage circuit simultaneously supporting a lithium battery and a dry battery, and an electronic lock. The electronic lock wide voltage circuit comprisesa main control part and a communication part, wherein the electricity is supplied to electricity use devices of the main control part by the voltage of the dry battery through a first dry battery input end, and the electricity is supplied to a microprocessor unit by the voltage of the dry battery through a first step-down transformer; the voltage of the dry battery sequentially enters a second step-down transformer and an MOS tube through a second dry battery input end, and is then input into electricity use devices of the communication part; the voltage of the lithium battery is input into adiode through a lithium battery input end and is then merged into the output end of the MOS tube to be input into the electricity use devices of the communication part; and the microprocessor unit isconducted with the lithium battery input end after the electronic lock is awakened. The lithium battery and the dry battery can be simultaneously supported; and the condition that the lithium battery cannot work cannot occur.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to an electronic lock wide voltage circuit and an electronic lock supporting both lithium batteries and dry batteries. Background technique [0002] Traditional electronic locks are usually powered by 6V dry batteries (4 1.5V), and some are also powered by lithium batteries (using the energy density of lithium batteries), but there is no way to replace them dynamically (users have no way to choose dry batteries or lithium batteries according to their own needs). The main control part of the electronic lock system generally uses 2.7-3.6V power supply. In order to maintain low standby power consumption, a low-power linear regulated power supply chip is usually used for the main control part (when the chip performs power conversion, the input and output current No change, the difference between the input voltage and the output voltage is lost on the power chip, and the work...
