Secure Locking Mechanisms for Mobile Phone Cases
25 patents in this list
Updated:
Mobile device case design has evolved from simple protective shells to sophisticated mechanisms incorporating multiple functions. Current designs must accommodate wireless charging, card storage, and medical sterilization requirements while maintaining device protection—all within strict dimensional constraints of less than 15mm total thickness and precise tolerances for button and port access.
The fundamental challenge lies in creating secure locking mechanisms that maintain robust protection while allowing convenient access and integrating additional functionality.
This page brings together solutions from recent research—including tension-spring-assisted covers for foldable devices, sterilizable enclosures with contamination seals, magnetic mounting systems for wireless charging, and secure wallet combinations with remote locking capabilities. These and other approaches demonstrate how manufacturers are addressing both security and functionality requirements in modern mobile case design.
1. Electronic Device Housing Locking Mechanism with Identity-Driven Actuation
LENOVO BEIJING CO LTD, LENOVO CO LTD, 2023
Locking device for electronic devices that allows secure disassembly without specialized tools. The device has a locking component between the device's housings that can move between locked and unlocked positions. A driving member moves the locking component. An identity recognition module connects to the driving member and identifies user identity. When an unauthorized user is detected, the module keeps the locking component locked. For authorized users, it unlocks the device. This prevents unauthorized disassembly while allowing authorized servicing without special tools.
2. Locking Mechanism with Elastic Rod Force Transmission and Arc-Shaped Lock Tongue for Foldable Electronic Devices
RONGYAO TERMINAL CO LTD, 2023
Locking mechanism for foldable electronic devices like folding phones that reduces friction and improves durability compared to existing mechanisms. The mechanism has a button, a locking member, and a linkage member. The locking member has a lock tongue that engages with the device housing. The linkage member connects the button to the locking member. The button moves the linkage member to slide the lock tongue between locked and unlocked positions. Elastic rods between the button and linkage provide force transmission without direct contact. This prevents friction between the button and locking member. The arc-shaped lock tongue contacts the housing smoothly. The button protrusions and housing grooves align. This reduces friction when folding/unfolding. The protrusions and grooves also align the button and housing for consistent assembly.
3. Cellphone Case with Integrated Bore and Retention Ring for Magnetic Wireless Charger Mounting
ANNEX PRODUCTS PTY. LTD., 2023
Mounting a wireless cellphone charger to a cellphone case for charging a cellphone when secured. A cellphone case has a bore, recess, and retention ring.

Applying pressure flexes a portion of the outer stand to release the lock and close the stand.
5. Protective Cover with Tension Spring Mechanism for Foldable Electronic Devices
CASE-MATE, INC., 2021
A tension-spring-assisted protective cover for foldable electronic devices like smartphones that prevents unintended opening or closing.

6. Electronic Device Housing with Automatic Locking Mechanism Featuring Interacting Latch and Action Member
WISTRON CORP, 2021
An electronic device housing with an automatic locking mechanism that eliminates the need for manual latching. The locking module has a base, a latch, and an action member. The latch moves between positions and has a groove. The action member also moves between positions and has a fixing part. In the unlocked state, the latch is in one position, the action member is in another position, the latch is in the groove, and the fixing part is separate. In the locked state, the latch moves, the action member moves, and the fixing part detaches from the groove. This automatic locking is triggered by the device body pushing the action member when closed.
7. Mobile Device Case with Automated Camera Lens Cover Mechanism
Eric Vélez Justiniano, 2021
This is a mobile device case with a camera lens cover that automatically opens and closes when the phone is unlocked and locked. When the phone is locked, the cover is closed. When the phone is unlocked, the cover automatically opens.
8. Friction-Based Mobile Phone Locking Mechanism with Fingerprint-Activated Motor and Lock Plate
BEIJING IEQUIP TECH DEVELOPMENT CO LTD, BEIJING IEQUIP TECHNOLOGY DEVELOPMENT CO LTD, 2020
Structure for locking a mobile phone by friction to provide an easy way to securely lock and unlock a phone without needing a padlock hole.

19. Mobile Phone Card Slot Locking Mechanism with Lever, Springs, and Sensor-Controlled Telescoping Plate
成都意町工业产品设计有限公司, 2018
Locking mechanism for mobile phone card slots to prevent unauthorized removal of SIM cards. The mechanism uses a lever, springs, and a sensor. When a card is inserted, a telescoping plate extends into the slot and separates the lever from a first spring. The lever then pushes out the baffle, compressing a second spring. A sensor at the bottom detects the card and sends a signal to a controller. The controller extends the telescoping plate again, locking the lever and baffle in place. This prevents card removal without the correct PIN or fingerprint. The lever and baffle are connected by springs to allow card insertion/removal.
