Description

Technical Field

[0001] This utility model relates to the field of electronic lock technology, and in particular to a cabinet door electronic lock structure. Background Technology

[0002] An electronic lock is an electronic device that uses electronic passwords, fingerprint recognition, and card swiping for opening and closing. A sensor-operated electronic lock is an electronic lock that unlocks automatically through sensing technology. It is widely used in various places, such as shopping malls, hotels, bathroom lockers, and food storage cabinets. It does not require a physical key and can be unlocked with a card, making it convenient and fast.

[0003] Existing electronic locks for cabinets typically employ a locking hook within the cabinet frame and a sliding plate inside the door. Upon closing, a motor drives the sliding plate, causing a latch on the plate to engage with the locking hook, thus locking the cabinet. A specific access card control circuit board then reverses the motor, causing the sliding plate to slide and disengage from the latch, unlocking the cabinet. However, the motor inside the door is often battery-powered. If the battery runs out, there is a possibility that the lock will fail to engage or disengage, rendering the electronic lock ineffective and reducing the user experience.

[0004] In response to the aforementioned technologies, there is an urgent need to design and develop an electronic lock structure for cabinet doors. A mechanical unlocking port is provided on the cabinet frame. Normally, the cabinet door can be opened and closed using an access card. When the battery inside the cabinet door is depleted, the cabinet door can be unlocked through the mechanical unlocking port, thereby improving the user experience. Utility Model Content

[0053] The implementation principle of the electronic lock structure for a cabinet door 3 in this application embodiment is as follows:

[0054] During the closing of cabinet door 3, limit switch 34 rotates with cabinet door 3 and abuts against cabinet frame 1. Lock hook 2 is inserted into through groove 33. Then motor 8 drives gear 2 81 to rotate. Under the connection of gear 2 81, tooth groove 42 and slide plate 4, slide plate 4 moves down, so that lock hole 41 is engaged with lock hook 2, which makes it easy to lock cabinet door 3.

[0055] When the lock hook 2 is stuck in the lock hole 41, the cabinet door 3 is locked, and the battery 310 is depleted, the mechanical lock 7 can be unlocked using the spare key. The sliding handle 53 drives the gear 52 to slide until it meshes with the rack 51. Rotating the handle 53 drives the gear 52 to rotate. Through the connection between the gear 52, the rack 51, and the slide plate 4, the slide plate 4 is moved upward, so that the lock hook 2 is no longer stuck in the lock hole 41, thus releasing the locked state of the cabinet door 3. This avoids the possibility of the electronic lock failing and causing the cabinet door 3 to be unable to unlock or unlock, improving the user experience.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
