Abstract

The invention discloses an intelligent lock door opening self-charging system and method, and relates to the technical field of intelligent locks, the intelligent lock door opening self-charging system comprises one and more than one piezoelectric element, a door handle, a rotating rod, a rotating bearing, a charge processing unit, a charging management module and an electric quantity storage unit, and the adjacent piezoelectric elements are fixed through fixing blocks; the rotating bearing is arranged at the rotating position of the door handle, the rotating bearing is meshed with one end ofthe rotating rod, the other end of the rotating rod is connected with one side of the piezoelectric element through a fixing block, and the other side of the piezoelectric element is fixed in the intelligent lock; the piezoelectric elements are electrically connected with the input end of the charge processing unit, the output end of the charge processing unit is electrically connected with the input end of the electric quantity storage unit, and the charging management module is electrically connected with the charge processing unit and the electric quantity storage unit. Aiming at the technical problem of inconvenience in external charging when the intelligent lock is out of power, the electric quantity can be generated by rotating the handle to unlock the intelligent lock.

Description

technical field [0001] The invention relates to the technical field of smart locks, in particular to a self-charging system and method for opening a smart lock. Background technique [0002] The smart locks sold on the market are all powered by dry batteries or lithium batteries, and there is no smart lock with self-charging function. The battery-powered smart lock will have the problem that the battery power is too low and cannot be used normally after being used for a period of time. Smart locks powered by dry batteries need to be replaced with new batteries, and smart locks powered by lithium batteries need to be removed and charged. The current smart locks have the function of alarming when the battery is low. For most smart lock users, it takes some economic and time costs to replace the battery. However, for smart lock users who travel frequently or are away from home for a long time due to certain factors, it is easy to encounter the situation that the smart lock ca...
