Anti-knocking single-lock-tongue double-system intelligent padlock

Abstract

The invention discloses an anti-knocking single-lock-tongue double-system intelligent padlock. A lock body is rotationally connected with an anti-knocking module positioned between a first unlocking part and a second unlocking part; a lock tongue is provided with a fit opening; the anti-knocking module comprises an anti-knocking rotating part and a return torsional spring; the anti-knocking rotating part comprises a head part rod body, a middle rod body perpendicular to a head part, and a rotating rod body extending down from the end, opposite to the head part, of the middle connecting rod; afirst driving rod and a second driving rod extend from the rotating rod body to the first unlocking part and the second unlocking part; the first unlocking part and the second unlocking part are provided with a first extrusion surface and a second extrusion surface corresponding to a first driving rod and a second driving rod; the first extrusion surface and the second extrusion surface can be rotated along with the first unlocking part and the second unlocking part to drive the rotating rod body before unlocking of the lock tongue to enable the head part rod body to deviate from the fit opening; and the return torsional spring is used for maintaining the head part rod body in the fit opening to prevent unlocking of the lock tongue.

Description

technical field [0001] The invention relates to the field of locks, in particular to an anti-knock single-bolt dual-system intelligent padlock. Background technique [0002] See figure 1 The Chinese invention patent with the publication number CN107419974A (identical to the applicant of the present application) discloses a padlock, comprising a lock body, a U-shaped lock beam, and an electronic lock core and a mechanical lock core fixed in the lock body. The beam includes a long lock bar, a short lock bar, and a connecting bar connecting the long lock bar and the short lock bar. The electronic lock core and the mechanical lock core are used to drive the lock tongue to cooperate with the lock beam to lock or Unlocking; the electronic lock cylinder includes a motor, a first rotating column parallel to the motor shaft, and a first connecting portion connecting the motor shaft with the first rotating column and the motor; the mechanical lock cylinder includes A lock cylinder s...

AI Technical Summary

Problems solved by technology

[0004] The elastic force of the locking compression spring of the padlock must be very large. This is because when the padlock lock body is struck suddenly, the lock body moves quickly. If the elastic force of the spring is relatively small, it is easy to cause the deadbolt to remain unchanged or change in position due to inertia. The small case causes the notch of the lock beam to separate from the lock tongue. If the spring force is relatively large, the output torque of the motor must be large. In order to meet the battery life requirements of the smart padlock, the battery capacity needs to be relatively large. This not only Increased cost will lead to larger volume of motor and battery
