Abstract

The invention relates to a power-saving actuator of a direct-current electronic lock, comprising a first shell, a second shell, a piezoelectric ceramic steel disc assembly, a circuit board and a convex tip unit, wherein the first shell and the second shell are combined and fixed mutually, and the top of the second shell is provided with a through hole; the piezoelectric ceramic steel disc assembly is formed by laminating a first piezoelectric ceramic steel disc and a second piezoelectric ceramic steel disc, wherein the first end of the second piezoelectric ceramic steel disc is a free end; the circuit board is electrically connected to the piezoelectric ceramic steel disc assembly; and the convex tip unit comprises a convex tip and a spring which are sleeved with each other, and the convex tip unit is positioned between the top of the first end of the second piezoelectric ceramic steel disc and a through hole. The circuit board applies a voltage to the piezoelectric ceramic assembly so that the first end of the second piezoelectric ceramic steel disc generates upwards inflected displacement changes and pushes the convex tip of the convex tip unit to outwards extend from the through hole, thereby a lock bolt is interfered and actuated.

Description

technical field [0001] The invention relates to an actuator, in particular to a power-saving actuator for a direct current (DC) electronic lock. Background technique [0002] The electronic lock is to control the extension or retraction of the deadbolt in an electric way, so as to achieve the function of locking or unlocking. [0003] There are generally two types of actuators for electronic locks according to their actuation methods. One is a motor-driven type, which drives the lock tongue through the gear through the rotation of the motor rotor to achieve the actuation effect; the other is a solenoid structure (so1enoid), also known as a solenoid valve, which uses an electromagnetic coil to generate magnetic force to control a protruding shaft. Drive the lock tongue to achieve the actuation effect. [0004] However, these existing known actuators all use the principle of coils to generate sufficient magnetic force, so they must be driven with a relatively large current a...
