Low-power-consumption intelligent electronic tapered end

Abstract

The invention discloses a low-power-consumption intelligent electronic tapered end, relates to an electric combination lock, and in particular relates to a tapered end of an electric combination lock. The invention aims at providing a low-power-consumption intelligent electronic tapered end without a position detection device on a circuit control part and with relatively smaller volume. The low-power-consumption intelligent electronic tapered end comprises an electronic control circuit part and a miniature motor 21, wherein a shifting rod 22 is arranged on a miniature motor rotating shaft. The low-power-consumption intelligent electronic tapered end also comprises a trip assembly, wherein the trip assembly comprises an assembly frame body 31, a demilune body 32 and a limit wafer 33, eccentric columns 34 are inserted on the assembly frame body and the limit wafer, limit cams 35 are sleeved on the eccentric columns, a locking marble 36 is slidably connected in the demilume body, a pressure spring 37 is sleeved on the locking marble, an upper arm 351 and a lower arm 352 are respectively arranged on the limit cam, and an elastic reset part is arranged above the limit wafer. When the lower arm is shifted by the shifting rod, the lower arm is separated from the rotating rail of the shifting rod, and the upper arm is separated from the barrier of the elastic reset part to be unlocked; and the reset is completed by the elastic reset part.

Description

technical field [0001] The invention relates to an electric number lock, in particular to a lock head of an electric number lock. Background technique [0002] At present, there is a kind of passive electronic lock in the field of electronic locks. This kind of lock has low power consumption. A low-power electronic padlock, the single-chip microcomputer control circuit in it is powered by the power supply inside the electronic key when the electronic key is inserted, the single-chip microcomputer control circuit recognizes the opening authority of the electronic key and drives the power part to realize unlocking. There is another Chinese utility model patent with application number 200720044286.9, authorization announcement number CN201092778Y, and authorization announcement date of July 30, 2008, which discloses a low-power electronic lock control circuit and key circuit, which can identify keys ID of the chip and issue an unlock command to drive the motor. At present, th...
