When understanding the smart lock, users often know the relevant structure and performance of the clutch first. There are three kinds of clutches in the smart lock: external, central and internal, but do you know which of these three clutches is safer? Xiaobian will introduce you to the difference between these three clutches today.
Due to the different positions of clutches, they are usually divided into external clutches, middle clutches and internal clutches.
External clutch
At present, the clutch scheme most used by various manufacturers, that is, the clutch actuator assembled in the outer guard plate of the intelligent door lock, generally controls the position movement of the clutch pin through the electric control device, resulting in manual idling or driving the lock body to unlock. Because most domestic security doors (engineering doors) are double-layer iron door structures, they are easy to be stolen.
Center clutch
Also known as in-lock clutch, electronic control auxiliary structures and devices are implanted in the mechanical lock to form the clutch working state, which belongs to the later improved optimization scheme, but its cost is high, the specifications are incomplete, the structure is complex, and it is extremely easy to steal it by using special tools.
Internal clutch
The clutch device installed in the inner guard plate of the door is safer and more reliable compared with the double protection of the outer guard plate and the door body.
Due to the characteristics of double-action and double-speed quick unlocking body, the clutch device should not only meet the needs of daily normal unlocking and clutch, but also have the basic preventive ability against large torsion and large torque damage. Only by effectively solving the structural safety shortcomings can we create a safe and convenient intelligent door lock. The core competitiveness of the post-intelligent lock era is the struggle for intelligent hardware security that supports various intelligent control schemes!
