Description

Technical Field

[0001] The present invention relates to the technical field of door lock components, in particular to an intelligent door lock. Background Art

[0002] Smart door locks refer to locks that are improved on the basis of traditional mechanical locks and are more intelligent and simple in terms of user security, identification, and management. Smart door locks are the executive components of door locks in access control systems. Smart door locks are different from traditional mechanical locks and are composite locks with greater security, convenience, and advanced technology. Existing smart door locks are mainly unlocked through fingerprints, passwords, and induction cards. After the internal chip is processed, the control motor drives the transmission parts to achieve the unlocking action. However, during use, the motor is damaged or the motor connection line is short-circuited and damaged, causing the motor to fail to operate. The motor output shaft is usually linked to the transmission parts through gears. After the motor loses power, the transmission parts will be locked, resulting in the inability to open the door lock normally through the handle or key, affecting the use of smart door locks and reducing the user experience.

It can be disengaged from the motor during the unlocking action, thereby smoothly unlocking the door by operating a key or an inner door handle.

[0004] To achieve the above-mentioned purpose, the present invention provides an intelligent door lock, including a shell, in which a driving motor, a main lock tongue, a beveled tongue, a square shaft, a lock core and a driving gear are arranged, the square shaft is drivingly connected with the beveled tongue and the main lock tongue, the lock core is drivingly connected with the beveled tongue and the main lock tongue, the lock core and the square shaft are drivingly connected with the driving gear through a transmission member, the driving gear is rotatably arranged in the shell, the driving motor is arranged at a position corresponding to the driving gear, a clutch is slidably sleeved on the output shaft of the driving motor, a positioning groove and a positioning block are arranged between the clutch and the driving gear, the positioning groove and the positioning block are engaged to form a driving motor driving the driving gear to rotate, and a resetting member is also arranged between the output shaft of the driving motor and the clutch. The clutch has a first return spring, and a swinging member is also provided in the shell, one end of the swinging member is provided with a resistance plate, and the other end is bent to form a first touch rod, and the clutch is circumferentially provided with a push groove, and the first touch rod extends in the push groove, and the swinging member also extends to the square shaft. A driving sleeve is sleeved on the square shaft, and the driving sleeve is provided with a driving flange corresponding to the position of the second touch rod for resisting the second touch rod to make the swinging member slide and drive the clutch to disengage from the driving gear. The shell is slidably provided with a driving plate for being driven and slipped by the lock core dial wheel corresponding to the position of the lock core, and the driving plate is provided with a driving step corresponding to the position of the resistance plate for resisting the resistance plate to make the swinging member slide and drive the clutch to disengage from the driving gear.

[0005] The beneficial effect of such arrangement is that, in normal use, the driving motor can be used to drive the transmission member to achieve unlocking; when the key is operated, the dial wheel on the lock core is rotated by the key, so that the dial wheel drives the driving plate to slide, and the driving plate drives the step corresponding to the contact plate position, thereby driving the swing member to swing, and the first contact rod at the other end of the swing member contacts the side wall of the push groove, thereby driving the clutch member to slide, so that the positioning block disengages from the positioning groove, so that the key continues to be turned to drive the main lock tongue and the oblique tongue to retract, thereby achieving the unlocking action; when unlocking by the inner door handle, the handle rotates to drive the square shaft to rotate, thereby causing the driving sleeve on the square shaft to rotate, and the driving flange on the driving sleeve contacts the second contact rod, driving the swing member to swing. When the first locking cam is engaged, the first contact rod at the other end of the swinging member abuts against the side wall of the pushing groove, thereby driving the clutch member to slide, so that the positioning block is disengaged from the positioning groove, so that the handle continues to be turned to drive the main locking tongue and the oblique tongue to retract, and the unlocking action is realized, which can effectively disengage the driving gear from the driving motor to avoid the driving gear being stuck by the driving motor. After the operation is completed, after the overall lock is reset, that is, after the main locking tongue and the oblique tongue are reset, under the action of the reset spring, the positioning groove and the positioning block are engaged, so that the driving gear can be driven by the active motor, thereby completing the action of electric unlocking and locking.
