[0057] Specifically, the principle of the present utility model is:

[0058] Controller housing design:

[0059] The controller housing of this utility model is divided into two parts, each designed as a semicircular open sleeve. This design allows the device to be easily inserted into the gap between the handle mechanical lock panel and the door panel from both sides. The two parts are connected by a guide shaft to form a single unit, ensuring the stability of the device and making the installation process extremely simple. In addition, this design allows the device to be used on door panels of varying thicknesses, expanding its application range.

[0060] Center distance adjustability:

[0061] To accommodate various brands and models of mechanical locks on the market, this device features an adjustable center distance. Specifically, the upper and lower half-circles of the housing can be adjusted to a preset distance of 50, 58, 68, 72, 85, or 92 mm, depending on actual needs. This flexible adjustment mechanism allows the device to easily adapt to a wide range of locks, whether standard or custom sizes.

[0062] Metal protective compartment and mechanical password lock:

[0063] The metal protective cage is a crucial security component, designed to protect the key inserted into the lock cylinder from external interference. A special hook structure is incorporated into the cage. When locked, the hook engages the cage, preventing unauthorized rotation. More importantly, the cage works seamlessly with the mechanical combination lock. Only when the user enters the correct combination does the mechanical combination lock release the cage, allowing the user to proceed. This design not only enhances security but also makes it more difficult for unauthorized intruders to access the cage.

[0064] Automation and intelligent control:

[0065] The protective compartment houses a gear compartment connected to an electronic control system. Under normal circumstances, the electronic control system actuates the mechanism within the compartment, enabling automatic locking and unlocking. This means users can control the lock's status electronically through pre-set electronic means (such as a mobile app or Bluetooth), eliminating the need to directly access a mechanical key. This intelligent operation significantly improves daily convenience and reduces the inconvenience caused by forgetting your keys.
