Mirror ratchet mutually-standby hand cranking power generation mechanism and non-power-source electronic lock

Abstract

The invention discloses a mirror ratchet mutually-standby hand cranking power generation mechanism which comprises a shell, a drive gear, a handle rotating shaft and two power source generation mechanisms. The drive gear is rotationally supported on the shell. The handle rotating shaft is connected with the drive gear. The two power source generation mechanisms are symmetrically arranged in the left-right direction. Each power generation mechanism comprises a drive gear, a ratchet mechanism, a power generator and a fixing plate. The power generators are installed on the fixing plates. The twodriven gears are engaged with the drive gear and are connected with rotors of the power generators through ratchet mechanisms correspondingly. By means of the power generation mechanism, double-power-source output is achieved. The invention further discloses a non-power-source electronic lock which comprises a shell, a rotating handle, a lock cylinder, a circuit board and the mirror ratchet mutually-standby hand cranking power generation mechanism. The mirror ratchet mutually-standby hand cranking power generation mechanism is installed in the shell, the rotating handle is installed on the handle rotating shaft, and the power output ends of the two power generators are electrically connected with two sets of control systems of a circuit board correspondingly. By means of the non-power-source electronic lock, a circuit is simplified.

Description

technical field [0001] The invention relates to a mirror image ratchet mutual backup type manual power generating mechanism, and also relates to a passive electronic lock using the mirror image ratchet mutual backup type manual power generation mechanism for power supply. Background technique [0002] The passive electronic locks currently on the market are to transfer the power of the lock to the key of the electronic lock. The operation of unlocking is the process of the key supplying power to the lock and mutual access. This is exactly in line with people's daily habits. After the work is over, the key can be connected to the background to upload the record, and indirectly achieve the same as the access control system, saving the opening and closing records of the relevant objects. [0003] The Chinese patent application number 201611129600.3 discloses a self-powered passive electronic lock, which adopts a dual power supply structure, one of which is generated by a manua...

AI Technical Summary

Problems solved by technology

[0004] 1. When in use, it is necessary to carry an inductive power supply to supply power to the control system through the inductive charging module, but the carrying of the inductive power supply brings inconvenience to the user;

[0005] 2. The power supply on one side needs to be electrically connected to two sets of control systems at the same time, and it needs to supply power to the two sets of control systems at the same time, and the two power supply circuits must be isolated in case of failure, which greatly increases the circuit in the passive electronic lock. Complexity;

[0006] 3. The manual charging mechanism cannot use the energy generated by inertia
