Entering the 21st century, China's biometrics technology has ignited a beacon fire, making the fingerprint lock industry developed rapidly. But the working life of some fingerprint locks is short, and it is difficult to meet the requirements of users for durability, convenience, safety and fashion. The same type of fingerprint lock, due to the design level, manufacturing quality, the use of the environment and customer use and management level is different, its service life will be greatly different. The key factors that affect the life of fingerprint lock are briefly discussed below, so as to discuss with readers.
According to the information of a domestic fingerprint lock manufacturer, the reliability design is the main factor to prolong the service life of the fingerprint lock. There are three main points that affect the service life of fingerprint lock:
1. lock structure design. The door lock is not safe, and the mechanical structure design of the lock is very critical. The key technologies that affect the structural design are lock core technology and clutch motor technology. At present, the most advanced lock core technology is the best combination of three-dimensional structure and gear transmission structure, such as: the United States standard five-tongue linkage electronic lock core, it is the safest product in line with ANSI international standards. Clutch motor technology should adopt the fifth generation of the world's most advanced variable speed gear clutch design, high reliability coefficient.
2. the overall manufacturing structure and material selection of the lock body. At present, the fingerprint lock with the most popular cast steel integrated structure is the most durable and durable.
3. the manufacturing process of the lock body. The life of the lock core treated with electrophoretic paint is much longer than that of the ordinary colored zinc plating. The circuit board is treated with anticorrosion, and the surface of the lock is treated with anticorrosion and anti-ultraviolet nanometer. All these are the technological guarantee of the long life of the door lock.
Some domestic companies have used the load analysis method to analyze the stress of the fingerprint lock accurately, and put forward the design of prolonging the life of the fingerprint lock (longevity design). As a specific fingerprint lock, its reliability design mainly involves four aspects: handle, lock core, clutch and surface treatment.
The reliability design of the handle should adopt permanent cylindrical positioning with bi-directional positioning springs to ensure horizontal state; with damping technology, friction sound should not occur between the metal bodies when opening; the handle should carry oil storage nest, always keep lubricating oil, and will not be affected by long time without lubricating oil friction. The clutch is in a state of idle rotation when the clutch is off, and the clutch is totally free of force. The clutch can prevent the clutch from destroying the handle and from destroying the internal structure by destroying the handle. The door lock.
The reliability design of American standard thin lock core adopts steel material. According to the principle of constant force transmission, double gear transmission structure ensures uniform force transmission, and transfers the force to the unlocking mechanism to the maximum extent when in use, so as to obtain the lightness and sensitivity when opening. The inclined tongue is positioned by rail type, and the anti-lock square tongue is designed by slope type. Its ruggedness and durability are enhanced five times, so that the overall service life and safety of the lock core are effectively guaranteed.
Variable speed gear clutch refers to the "core" part of the ripple lock. Its reliability design is shown in the following aspects: stainless steel pin, double balance spring design, double gear technology with gearbox. The material is imported from GE Company, USA, and the rotating power of the motor is not directly used. The rotating power of the motor is enlarged by 10% by using double gear drive. The higher the torque, the higher the rotational speed, the higher the reliability, the longer the service life, the 50% lower the power consumption, thus reducing the power consumption, prolonging the service life of the battery, improving the overall reliability and increasing the service life. The traditional clutch uses direct drive method, which uses the rotating force of the motor to drive the bar directly. The torque obtained is very small, the rotating speed is also small, and the power consumption is very large. It can not guarantee the "long life" of the fingerprint lock.
The reliability design of lock material and surface treatment mainly includes that lock body should adopt the integrated manufacturing technology of precision all-metal cast steel, no chip processing, no artificial rivet and plastic parts in the lock body. The special technology ensures that the lock is more durable, impact-resistant, never loose, and fully meets the public environment. More destructive and longer service life. The same surface treatment should adopt advanced nano-technology (PVD) treatment, can improve the corrosion protection ability of the substrate electronic lock, can resist atmospheric, ultraviolet radiation, high hardness, high wear resistance, in appearance to ensure that the fingerprint lock is as new as ever.
