In the 21st century, China's biometric technology has ignited campfires, which has enabled the fingerprint lock industry to develop 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. Fingerprint locks of the same model will have huge differences in their service life due to their different levels of design, manufacturing quality, use environment, and customer use and management.
First, the main factor in extending the life of fingerprint locks is reliability design.
There are three main designs 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 technologies that affect structural design are mainly the lock cylinder technology and the clutch motor technology. The most advanced lock cylinder technology is currently the best combination of three-dimensional structure and gear transmission structure.
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 in the world is the most solid and durable.
3. Lock body manufacturing process. The cylinders treated with electrophoretic paints are much longer than those of general zinc plating. The circuit boards are protected against corrosion and the surfaces of the locks are treated with anti-corrosion and anti-ultraviolet radiation. These are the "short-lived" protections of the door locks.
The load analysis method was used to accurately analyze the stress of the force components of the fingerprint lock, and a design to extend the life of the fingerprint lock was proposed. Specifically, a fingerprint lock was designed, and the reliability design mainly involved handles, cylinders, clutches and surface treatments. Four aspects.
The reliability of the handle design, the use of never-creased cylindrical positioning, with two-way positioning springs, to ensure horizontal state; the use of damping technology, should not produce friction between the metal body when opening; handle with oil storage nest, always have lubrication The oil will not affect the use due to the long use time and no friction of the lubricating oil. The idling design of the handle adopts the new “Segregated Fully-closed Motor Clutch Design†technology. When the clutch is closed, the handle is subjected to force when the clutch is disengaged. The handle is idle and the clutch is completely free from force. It truly prevents damage to the handle and prevents the door from being damaged by breaking the handle and damaging the internal structure.
The specification of the reliability design of the thin lock cylinder adopts steel materials. According to the principle of constant force transmission, the dual gear transmission structure ensures uniform force during transmission, and maximizes the force transmission to the unlocking mechanism when used, so as to obtain the opening The feel of light and sensitive. The inclined tongue adopts the guide rail positioning motion, and the anti-locking large tongue adopts the ramp type design, and the robustness and the durability are enhanced by five times, so that the overall service life and safety of the lock cylinder are effectively guaranteed.
The reliability design of the lock body material and surface treatment mainly includes the lock body adopting the precision all-metal cast steel integrated manufacturing process, free from chip processing, and there should be no artificial rivets and plastic parts inside, and the special process ensures that the door lock is more robust and durable. , Impact resistance, never loose, fully meet the use of the public environment, stronger resistance to damage, longer life. Similarly, the appearance of the surface should be treated with advanced nanotechnology (PVD technology, which can improve the corrosion protection of the substrate, can withstand the atmosphere, anti-ultraviolet radiation, high hardness, high abrasion resistance, appearance to ensure that the fingerprint lock is as new as ever.
Second, stability design usually affects the stability of the electronic lock, there are three major factors, including:
1. The above-mentioned lock cylinder structure and clutch structure stability and reliability;
2. The stability and reliability of the motor working state, the inspection criteria is to see if the use of a carbon brush motor;
3. The local stability and anti-interference of the logic circuit, the inspection criteria is to see if there is a protection circuit design.
Good maintainability & use of new materials If the fingerprint lock is easy to maintain and easy to repair, the “quick-cost quick repair†can be used to make the fingerprint locks always in a good technical condition. Once a malfunction occurs, it can be quickly repaired at a low cost. There is no need to replace new parts or new fingerprint locks, which actually extends the life of the fingerprint lock.
In addition, when designing fingerprint locks, the selection of suitable new materials based on fingerprint lock performance specifications and requirements is also a good way to extend the service life of fingerprint locks. For example, if the lock shell is made of alloy material and the nanometer-processed fingerprint lock, it is always better than plastic. The lock body must be durable and easy to maintain. Prerequisites: The fingerprint lock, password, and mechanical key are the three-in-one unlocking functions that are currently used in the market. The fingerprint lock is installed, and three types of opening methods are tested. After being qualified, under normal circumstances will no longer use the mechanical key password keyboard will be used often, but the case of using a password to open the door is also the role of a rare password is mainly used to power, in order to use fingerprints to open the door. From the perspective of the rationality of the design, the role of the password is very good. If the password is entered incorrectly, the fingerprint lock will not be powered on. The first is that the fingerprint cannot be used and the second is the power saving. Fingerprint locks, as the name suggests, use fingerprints to open the door. The cost of using a living human fingerprint is zero, and fingerprints are not a reasonable and unreasonable problem. Therefore, as long as you open the door with a fingerprint, you can ensure that the fingerprint lock is healthy and “short-lived†will not cause frequent occurrence of fingerprint lock failure, will not affect the normal use of the fingerprint lock, will not shorten the service life of the fingerprint lock, and will not make the fingerprint lock. damage.
In addition, the environmental factors in different regions will also affect the life of fingerprint locks, such as temperature and humidity, air pressure, pollution, light, rain and snow. When purchasing a fingerprint lock, you should not neglect the environmental factors you are in. You should select a fingerprint lock that meets the conditions. Many manufacturers have shown that their products are resistant to harsh environments, but it is best to make a decision after comparing them. The move.
Third, routine maintenance & timely maintenance and repair work is an important part of extending the life of the fingerprint lock, using reasonable maintenance methods can effectively extend the life of the fingerprint lock. Must do a good job of daily maintenance of the fingerprint lock, so that the fingerprint lock to maintain a good state of technology; to properly use and operate the fingerprint lock, reduce and prevent fingerprint lock failure caused by human error. We must do regular and irregular maintenance properly and reasonably, insist on the cleanliness and cleanliness of fingerprint locks, regularly check the technical status of fingerprint locks, find abnormalities and dispose of them in time, and timely tighten and adjust loose and misaligned parts. Preventive replacement of damaged parts.
The current domestic low-cost rapid repair method proposed by some domestic manufacturers is also an effective method to extend the lifespan of fingerprint locks or parts. In addition to the fingerprint lock design, this method adopts a maintenance design to improve the maintainability of the fingerprint lock. Exquisite technology, skilled operation, and thoughtful service are the indispensable conditions for extending the service life of fingerprint locks.
