AI Technical Summary
Existing remote-controlled central locking systems lack a double-locking structure, making them vulnerable to forced entry and unable to effectively resist attacks from professional thieves.
After the main bolt is inserted into the lock cylinder sleeve, the pop-out magnet on the lock cylinder sleeve attracts the pop-out magnet on the second bolt, causing the second bolt to pop out and insert into the slot, forming a double locking structure and enhancing the anti-theft performance.
This makes it more difficult for doors or locked objects to be forcibly pried open, significantly improving anti-theft and security performance and effectively preventing illegal intrusion.
