Electric lockset

Abstract

The invention provides an electric lockset. A separation and reunion mechanism composed of a driven gear and a rotating disc is adopted. A mounting position where the rotating disc is embedded is arranged on the first face of the driven gear, an arc-shaped concave position is arranged on the side wall of the mounting position, an arc-shaped convex block corresponding to the arc-shaped concave position is arranged on the outer side wall of the rotating disc, the central angle corresponding to the arc-shaped concave position is marked as alpha, the central angle corresponding to the arc-shaped convex block is marked as beta, and alpha and beta meet the condition that (alpha-beta) is greater than or equal to 180 degrees. Based on the structure, a rotating virtual position which is greater than or equal to 180 degrees exists between the driven gear and the rotating disc, that is, regardless of any angles, at which the gear drives the rotating disc to rotate, the gear can rotate at least 180 degrees, so that a rotary knob can stay in multiple positions when a lock is manually locked and unlocked. The electric lockset has the advantages of being high in practicality, good in operating hand feeling, free of reference with power supply stability and the like, and is simple in structure, simple in control logic and low in design cost.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to an electric lock. Background technique [0002] In addition to relying on the motor to control the switch, the existing electric locks can also manually rotate the switch, which brings some problems: since the lock body and the motor inside the lock are always connected, when the lock is manually switched, the motor will be turned on and off. Driven in reverse, thus generating reverse electromotive potential energy, which interferes with the stability of the power supply; moreover, the resistance generated by the motor makes the user have to use a large force to twist the lock body, which has a poor hand feel and cannot be locked quickly. [0003] In view of the above problems, the electric locks currently on the market are generally equipped with a motor return mechanism, that is, after the motor drives the lock body to perform the opening and closing action, the motor returns in ...

[0002] In addition to relying on the motor to control the switch, the existing electric locks can also manually rotate the switch, which brings some problems: since the lock body and the motor inside the lock are always connected, when the lock is manually switched, the motor will be turned on and off. Reverse drive, thus generating reverse electromotive potential energy, which interferes with the stability of the power supply; moreover, the resistance generated by the motor makes the user have to use a large force to twist the lock body, which has poor hand feeling and cannot be locked quickly

However, the motor back-off mechanism generally has problems such as complex structure, complex control logic, and high design cost, which is not conducive to popularization and application.
