Problems solved by technology

[0002] At present, mechanical locks represented by tumbler locks and smart locks represented by fingerprint locks are widely used. The keys (mechanical keys or fingerprints) of these two types of locks are easy to be extracted and copied, and the security is insufficient.
The "Optical Key" (Patent No. CN102926587A) proposed in the past few years using flash frequency identification can be cracked by adding a photosensitive element inside the lock body to record it; Classification and matching of light sources with different wavelengths is very costly; "A Holographic Optical Lock" (Patent No. CN102383669A) uses the surface optical characteristics of the key to identify, which is very difficult to identify and is very susceptible to external factors such as temperature, humidity, and pressure. interference, while the cost is very high

Embodiment Construction

[0017] The key includes 1. key shaft, 2. key handle, 3. key rib body, 4. key body alignment hole. 1. The key shaft is made of translucent hard material with random cracks inside; 2. The key handle is made of hard wear-resistant plastic, which is easy to hold; 3. The key rib is made of semi-transparent hard wear-resistant material or wear-resistant material , fit the lock hole; 4. The alignment hole of the key body is a small hole opened on the 3. key rib, which is used to interact with the 13. alignment transmitter and 14. alignment receiver to determine whether the key is inserted correctly. Location.

[0018] The lock body includes 5. Cylinder body, 6. Rib fitting groove, 7. Linkage alignment protrusion, 8. Inner cylinder wall, 9. Outer cylinder wall, 10. Cylinder support frame, 11. Light source array, 12. Photosensitive Array, 13. Alignment transmitter, 14. Alignment receiver, 15. Linkage alignment groove, 16. Sensing / air guide hole, 17. Motor turntable, 18. Cable manageme...

Abstract

The invention provides a dynamic recognition multi-segment optical lock in order to increase the difficulty of key replication, decrease the mutual opening probability and improve the safety. A motordrives a key body for rotation and synchronous recording so as to obtain inside and outside all-around information of a key, the complexity is increased, and the safety is improved.

Description

technical field [0001] The invention relates to a lock, especially an optical lock. Background technique [0002] At present, mechanical locks represented by tumbler locks and smart locks represented by fingerprint locks are widely used. The keys (mechanical keys or fingerprints) of these two types of locks are easy to be extracted and copied, and the security is insufficient. The "Optical Key" (Patent No. CN102926587A) proposed in the past few years using flash frequency identification can be cracked by adding a photosensitive element inside the lock body to record it; Classification and matching of light sources with different wavelengths is very costly; "A Holographic Optical Lock" (Patent No. CN102383669A) uses the surface optical characteristics of the key to identify, which is very difficult to identify and is very susceptible to external factors such as temperature, humidity, and pressure. interference, and the cost is very high. In "Polarization-Based Optical Locks...
