Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of lockset, specifically relates to an electronic lock. BACKGROUND

[0002] Electronic lock, as an important part of modern smart home and security field, realizes the intelligent control of door lock through the combination of electronic technology and mechanical structure. It can not only be unlocked by password, fingerprint, card and other ways, but also has advanced functions such as automatic locking and alarm prompt, which greatly improves the security and convenience of the door lock.

[0003] In the field of electronic lock technology, the existing electronic lock products have realized the function of automatic locking. This design uses the elastic expansion mechanism of the lock tongue. When the door leaf is closed and the lock tongue touches the door frame, the lock tongue will automatically expand and contract, thereby realizing the locking state of the door leaf. This mechanism is particularly useful in outdoor environments, significantly improving the security of the door lock and effectively preventing unauthorized entry, providing a more secure living environment for users.

[0004] However, when the electronic lock is applied to indoor environments, its automatic locking function exposes some problems. In indoor spaces, users often need to frequently enter and exit rooms, for example, in a home environment, family members may need to frequently enter and exit the bedroom, kitchen, living room and other areas; in an office area, employees may need to frequently enter and exit meeting rooms, offices and other places. At this time, if the electronic lock continues to perform the automatic locking function, it will bring great inconvenience to the user.

[0005] Specifically, if the electronic lock continues to automatically lock in an indoor environment, the user needs to perform an unlocking operation each time they enter or exit the room, which not only interrupts the user's normal activity process and reduces efficiency, but also may cause unnecessary trouble and distress. For example, when the user is holding an object or in an emergency, frequent unlocking may increase the user's burden and risk. In addition, for some special groups such as the elderly, children or the disabled, frequent unlocking may become a major problem in their lives.

[0006] In addition, from the perspective of production and manufacturing, the existing electronic lock structure is relatively complex, containing multiple precise mechanical components and electronic elements. This not only increases production costs, but also may lead to increased failure rates and increased assembly difficulty during production. Therefore, simplifying the structure of the electronic lock and improving production efficiency have become a technical problem to be solved. INVENTION CONTENTS

[0018] Compared with the prior art, the utility model has many aspects, including but not limited to:

[0019] The motor, the locking assembly and the lock tongue of the electronic lock are sequentially connected in drive, so that the movement of the lock tongue is more accurate and controllable. The power provided by the motor ensures that the lock tongue can stably reach the predetermined first lock position, and the introduction of the magnetic attraction assembly further enhances the stability of the lock tongue in the position, reducing the risk of lock tongue loosening caused by vibration or external force interference. The traditional electronic lock often relies on a single mechanical or electronic lock tongue to realize locking, and the electronic lock of the utility model drives the locking assembly by the motor, and then drives the lock tongue to move to the first lock position, and uses the magnetic attraction assembly to locally attract the lock tongue out of the lock body for locking. This design not only increases the complexity of locking, making it more difficult for illegal intrusion, but also can provide a smoother and faster unlocking experience when the user is authorized to unlock, because the magnetic attraction can assist the rapid homing or release of the lock tongue.

[0020] The magnetic attraction assembly of the electronic lock only needs to locally attract the lock tongue during the locking process, compared with completely relying on mechanical force or a larger power motor to control the movement of the lock tongue, the utility model is more efficient in energy utilization efficiency. At the same time, due to the magnetic attraction, the direct friction between the lock tongue and the door frame is reduced, which helps to reduce the wear of parts in the long run and prolong the service life of the electronic lock.

[0021] The electronic lock of the utility model can realize accurate control of the movement of the lock tongue through the cooperation of the control unit and the motor. When needed, the control unit can instruct the motor to drive the locking assembly, so that the lock tongue remains in the unlocked state, thereby avoiding the automatic locking of the lock tongue due to the closure of the door body. This design enables the user to not need to perform unlocking operation every time when frequent access is needed, greatly improving the use experience. Since the lock tongue can remain in the unlocked state for a long time or be unlocked through the magnetic attraction assembly, the electronic lock of the utility model is particularly suitable for indoor environments that need to frequently open and close doors, such as homes, offices, hospitals and the like.
