Drawers or cabinets are an important storage space in our daily lives. In general, there are multiple drawers in the home or office. Most of the things in the drawer are personal items. To protect personal privacy or belongings, we usually use a lock for drawer or cabinet to lock. However, problems such as the loss of keys and the inability to open the drawers and cabinets are often encountered. These are the problems that need to be solved in the development of home automation.
Why choose the gear motor from ZHAOWEI
In order to improve the reliability of unlocking and locking of the intelligent drawer, Zhaowei uses the industry’s smaller 3.4MM, 4MM planetary gearbox to achieve the transmission demand of small volume and large torque. The gearbox structure has two-stage, three-stage, four-stage transmission changes,so the reduction ratio can be changed and and the input speed and torque of the gearbox can be adjusted according to the design requirements of the starter motor of the drawer lock. After the information is transmitted, the correct information is checked and make feedback. The corresponding feedback is sent by sending different commands to the circuit board that can accept the Bluetooth information, and then the motor starts to drive the gear and the straight rack, and pushes the bolt up and down,realizing the effect of the switch.
The unlocking latch of the general cabinet lock is controlled by the front panel, and the Zhaowei intelligent drawer cabinet lock gearbox solution uses the reduction gearbox and the motor in the transmission of the lock cylinder. The cylinder can effectively be controlled through the transmission of the gear motor.This design makes the lock cylinder controllable, high reliability (avoiding the situation that the intelligent lock cannot be opened), long service life, achieving the safety and reliability of unlocking the intelligent drawer cabinet.
Wear of plastic Gear is a big difficulty
In the market, the gears of some cabinets of lockers, whether gears or straight racks, are mostly plastic. If they are used for a long time, they will wear out, causing the meshing drive to be out of sync. Simply put, Locking the door tongue will closed incompletely. To solve this difficulty, we used POM materials and optimized the performance of the gearbox and gear structure at the beginning of the design. Using kinematics simulation and finite element analysis, the gearbox integrated design platform is used to realize the automatic parameter design of the involute planetary gear system, bevel gear, face gear and other mechanisms.By optimizing the gear parameters, such as the displacement coefficient, the tooth coefficient, the pressure angle, the center distance, etc., the meshing shock velocity is reduced. the ratio of the impact velocity is within a certain range, and the impact of the joint circle is reduced, solving the requirement of low noise in use.The intelligent drawer cabinet lock gearbox is suitable for centralized control cabinets such as lockers, letter boxes, lockers, logistics cabinets, file cabinets, meter boxes, lockers, vending machines, mobile phone cabinets, shoe cabinets, etc. And widely used in schools, community logistics, hotels, factories, bathing centers, banks, supermarkets and other places.
