Description

Technical Field

[0001] This utility model relates to the technical field of locks and their peripheral supporting facilities, and in particular to a waterproof electronic lock. Background Technology

[0002] Achieving waterproofing in existing lock technologies consistently faces structural challenges. When a lock is locked, its core components are enclosed in a sealed cavity, forming a basic waterproof barrier through the physical isolation of the shell. However, unlocking triggers the mechanical transmission mechanism, creating an opening that directly connects the sealed cavity to the external environment. This opening becomes a weak point in the waterproofing function.

[0003] When unlocked, external water, moisture, and dust can directly enter the lock through this opening, rendering it waterproof after unlocking. Adding a waterproof structure inside the interconnected opening presents technical challenges due to the moving parts. The moving part of a lock is typically the latch, which needs to reciprocate during unlocking and locking, and its trajectory must traverse the boundary between the sealed cavity and the outside environment. Achieving reliable waterproofing on moving parts is far more complex than on static structures.

[0004] Electronic locks eliminate the need for traditional keys and support multiple unlocking methods such as fingerprint, password, and facial recognition. Due to their high convenience, electronic locks are increasingly favored by users. However, waterproofing electronic locks requires dual protection for both mechanical moving parts and electronic components, and they also face the aforementioned challenges. Furthermore, because electronic locks have a large number of additional electronic components compared to mechanical locks, such as circuit boards, sensors, and battery compartments, these components are more sensitive to water and moisture. If waterproofing fails, it can not only cause mechanical jamming but also directly lead to electrical faults such as short circuits and component corrosion, severely affecting the lock's functionality.

[0005] Existing electronic locks typically place the unlocking mechanism and the PCBA (Printed Circuit Board Assembly) in the same cavity, sealing the entire structure for waterproofing. However, waterproofing has always been a challenge for electronic locks due to the presence of moving parts in the unlocking mechanism and the opening between the cavity and the outside after unlocking.

[0006] Therefore, how to change the current situation where it is difficult to achieve waterproof performance in electronic locks has become an urgent problem to be solved by those skilled in the art. Utility Model Content
