Compared with ordinary mechanical locks, the design of intelligent door locks is more convenient to use and has a higher safety factor. It not only supports fingerprints, passwords, magnetic cards, but also supports mobile phone APP connection. There are many different ways to open the door lock. In the process of designing intelligent door locks, designers consider appearance design, structural design, hand board production, material selection, man-machine, color matching, etc., and pay attention to details. The design of the intelligent door lock is inspired by the appearance of the sports car. The appearance design is simple and atmospheric, and the shape is unique and novel. It outlines an elegant form with concise lines, pursues a sense of speed and strength, and reduces the bulky atmosphere of metal. In the design process of the intelligent door lock, people's usage habits are fully taken into account. The door handle is hollowed out to facilitate the cost of opening the key. The handle is located at the upper end, and the lock hole is avoided at the lower part. The shield outline reflects the safe brand culture. The edge of the intelligent lock adopts curved design to enhance the comfort of the hand, and the sliding door is more labor-saving. Fingerprint unlocking is located in the front section, when entering the password to unlock, the numbers in the keyboard area will emit bright light, and the numbers can be seen very intuitively and clearly, which is convenient to use. The material selection is metal and the design of a large-area black translucent acrylic panel, which forms a sharp contrast; the lock body is made of high-quality zinc alloy integrated precision die-casting, with a built-in C- class anti-theft lock cylinder, which perfectly combines traditional mechanical technology and modern high-tech Fingerprint identification technology; the workmanship is exquisite and the surface treatment is smooth. The installation and design of the intelligent door lock are very simple, and it does not require professional personnel to carry out the installation operation. It can be installed by itself according to the instructions, which is very convenient.
