Why do smart locks use free handles?

When buying a smart lock, I often hear that sales staff will say that the handle is free when introducing the handle, and the handle clutch design technology is adopted. For non-industry personnel, they often hear it at a loss, then what is free Where's the handle? What is a free handle? The free handle is also known as the safety handle. The free handle is only for semi-automatic smart locks. Before passing the authentication (using fingerprints, passwords, proximity cards, etc. to unlock instructions), the handle is in an unstressed state. When you press down on the handle, the handle will turn, but it will not drive any device and cannot be unlocked. Lock. Only after passing the certification, the motor drives the clutch, and then presses down the handle to unlock it. Advantages of using free handles 1. Anti-violence and strong pressure on the handle. Under normal circumstances, people will not force the handle after knowing that the door is locked. However, some people with ulterior motives will destroy the internal parts of the lock by forcing the handle to achieve the purpose of illegal unlocking. The use of free handles leaves them nowhere to use force, so that the security performance of the smart lock can be improved. 2. Extend the life of electromechanical components. Children’s natural movement is fun, and they also love to play games of opening and closing doors. Not only do they play their own homes, but they also like to press and open the doorknobs of other people’s homes. Many children are because Playing the door opening and closing game more or less has been injured, and often pressing down the handle will affect the service life of the smart lock. The design principle of the free handle: After the smart lock is correctly authorized, the motor drives the clutch to close, and the handle is forced; after a few seconds, the motor stops working, the clutch is disengaged, and the handle is idling. This design can prevent the damage of the handle from affecting the life of the electromechanical components, and can also reduce the injuries caused by children playing with the door handle. 3. The anti-trailing free handle also has an important function to prevent trailing. The time for the motor to drive the clutch is only 6-10 seconds. As long as the lock is quickly locked after entering the house, when the person behind presses down the handle, it is idling again, which completely eliminates the possibility of trailing. 4. Reverse lock is more convenient. With this design, users only need to gently lift the handle to achieve reverse lock after going out, which is safe and saves time and effort.
