In the 21st century, China's biometric technology has ignited a bonfire, and the fingerprint lock industry has developed rapidly. However, some fingerprint locks have a short working life and it is difficult to meet the requirements of users for durability, convenience, safety and fashion. The same type of fingerprint lock has a huge difference in service life due to different levels of design, manufacturing quality, use environment, and customer usage and management. The following briefly introduces the key factors affecting the life of the fingerprint lock to discuss with the reader.
According to the relevant information of a fingerprint lock manufacturer in China, the main factor for extending the service life of the fingerprint lock is reliability design. There are three main points in the design that affect the life of the fingerprint lock:
1. The structural design of the lock. The door lock is not safe and the mechanical design of the lock is critical. The technology that affects structural design is mainly the lock core technology and clutch motor technology. Currently most advanced cylinder technology is the best combination of three-dimensional structure and the structure of the transmission gear, such as: American Standard latch linked electronic lock core, which is in line with international standards of ANSI safest products. Clutch motor technology should adopt the fifth generation of the world's most advanced variable speed gear clutch design with high reliability factor.
2. The overall manufacturing structure and material selection of the lock body. At present, the fingerprint lock using the most popular cast steel integrated structure in the world is the most sturdy and durable.
3. The manufacturing process of the lock body. The lock core treated with electrophoretic paint has a much longer service life than the general zinc plating. The circuit board is treated with anti-corrosion treatment, and the lock surface is treated with anti-corrosion and anti-ultraviolet nano-treatment. These are the technical guarantees for the “longevity” of the door lock. .
Domestic companies have used load analysis methods to accurately analyze the stress of the force-receiving parts of the fingerprint lock, and proposed a design to extend the life of the fingerprint lock (longevity design), specifically to a fingerprint lock, its reliability design is mainly It involves four aspects: handle, lock cylinder, clutch and surface treatment.
The reliability design of the handle should adopt a cylindrical positioning that is never loose, with a two-way positioning spring to ensure the horizontal state; using damping technology, the friction sound should not be generated between the metal bodies when opening; the handle should be with the oil storage nest, always keep Lubricating oil, will not affect the use due to long use time and no friction of lubricating oil; the idling design of the handle adopts the new "detached fully enclosed motor clutch design" technology, when the clutch is closed, the handle is stressed, when the clutch When disengaged, the handle is idling, the clutch is completely unstressed, and it is truly prevented from damaging the handle, and the internal structure is prevented from being broken by breaking the handle.
The reliability design of the American standard thin lock cylinder adopts steel material. According to the principle of constant force transmission, the double gear transmission structure ensures the uniform force during transmission, and the force is transmitted to the unlocking mechanism to the maximum extent during use. Lightweight and sensitive when opened. The inclined tongue adopts the rail type positioning movement, and the anti-locking large tongue adopts the slope type design, and the sturdiness and durability are enhanced by five times, so that the overall service life and safety of the lock cylinder are effectively guaranteed.
The variable speed gear clutch is the "core dirty" part of the fingerprint lock. Its reliability design is characterized by: stainless steel execution pin, double-fixed spring design, double gear technology with gear box, material imported by American GE company, not directly Using the rotational force of the motor, the driving force of the double gear is used to amplify the rotational force of the motor by 10 times to obtain the speed ratio and increase the torque. The greater the torque, the higher the speed, the higher the reliability, the longer the service life, and the lower the power consumption. %, thereby reducing power consumption, extending battery life, improving reliability and increasing service life as a whole. The conventional clutch adopts the direct drive method, and directly drives the lever by the rotational force of the motor. The obtained torque is very small, the rotation speed is small, and the power consumption is large, and the "longevity" of the fingerprint lock cannot be guaranteed.
The reliability design of the lock body material and surface treatment mainly includes the lock body should adopt the precision all-metal cast steel integrated manufacturing process, free of chip processing, and there should be no artificial rivets and plastic parts inside. The special process ensures that the door lock is more sturdy. Durable, impact resistant, never loose, fully meet the needs of the public environment, more resistant to damage, longer service life. The same surface treatment should be treated with advanced nano (PVD) technology to improve the base electronic lockCorrosion protection ability, can withstand the atmosphere, UV protection, high hardness, high wear resistance, in the appearance of ensuring fingerprint locks for many years.
