Abstract

The invention provides an engaging-disengaging structure and a fingerprint lock, wherein the engaging-disengaging structure includes a protrusion and a cavity which may cooperate with each other to limit the relative rotation of an output shaft and an auxiliary gear; the protrusion is made of an elastic material. When torsion having magnitude of K is applied to the protrusion, the protrusion elastically deforms and slides out of the cavity; K is greater than the magnitude of driving force of the output shaft driving the auxiliary gear to rotate, wherein the protrusion is arranged on the sidewall of the output shaft; the cavity is arranged in the auxiliary gear and is used for being fitted the wall of a shaft hole of the output shaft, and alternatively, the protrusion is arranged on the auxiliary gear and used for being fitted to the wall of the shaft hole of the output shaft; the cavity is arranged in the sidewall of the output shaft. The engaging-disengaging structure can prevent tooth breaking for a transmission gear in a transmission case.

Description

technical field [0001] The invention belongs to the technical field of locks, in particular to a clutch structure and a fingerprint lock. Background technique [0002] Existing fingerprint locks generally include a fingerprint verification unit, a motor that is driven and connected to the fingerprint verification unit, a cover that is driven and connected to the motor, a transmission that is connected between the cover and the motor, and a housing for rotating and installing the cover. , wherein the initial state of the cover is open (relative to the housing open), when the fingerprint verification is passed, the fingerprint verification unit drives the motor to start, the motor transmits the driving force through the gearbox and drives the cover to rotate to the closed state. Since the cover plate in the open state is easily rotated by the action of external force, and the external force acts on the transmission gear of the gearbox through the transmission of the cover plat...
