Drawers or cabinets are an essential type of storage system we use on a daily basis, at places including the office, and at home. Because most of what we store in drawers are private and/or personal, we typically lock our drawers or cabinets to protect our belongings. However, problems including losing keys, or being unable to open drawers and cabinets, often appear. These issues need solving in order to achieve a higher level of home automation.
Using embedded technology, the smart drawer terminal collects data through IoT sensors such as RFID, and then transmits the collected data to the controller for processing. After processing, the entire terminal operates through various sensors, including GSM SMS reminder, RFID identification, etc. Whether it is a plane lock, a link lock, or a cross-type door lock, the safety and reliability of a lock mainly depends on the gear motor of the lock cylinder.
Why Choose ZHAOWEI's Gear Motors?
In order to improve the reliability of locking and unlocking smart drawers, ZHAOWEI uses miniature 3.4MM, 4MM planetary gearboxes to achieve the transmission demand of quieter volumes and high torque. 2-stage, 3-stage, and 4-stage transmission changes are available in order for the reduction ratio, input speed, and torque, of the gearboxes to be customized according to the design requirements of the starter motor of each drawer lock. The information is then transmitted, and checked for correctness, before feedback is given. Feedback is sent via different instructions, to the circuit board via Bluetooth. The motor then starts to drive both the gear and spur rack, and pushes the bolts up and down to achieve the effect of a switch.
The latch of a cabinet's lock is controlled by the front panel. The ZHAOWEI gear drive system consists of the precision gearbox and micro motor, which both help to effectively control the transmissions of the smart lock cylinder. This gearbox design makes the lock cylinder safe, reliable, and durable.
A Grave Problem: Plastic Gear Wear and Tear
Most gears and spur racks of lockers and cabinets in the market are made of plastic. Using them over time will cause them to wear out, making the meshing drive go out of sync. This means that door latches aren't able to completely close when being locked. To solve this grave problem, ZHAOWEI utilizes POM materials in the initial design stages to optimize the performance of the gearbox, as well as the gear structure. Using the analysis of kinematics simulation and finite element, the integrated design platform for the gearbox helps fulfill the automatic parameter design of the involute planetary gear system, bevel gear, face gear and other mechanisms. By optimizing the gear parameters, which include displacement figures, tooth figures, pressure angles, the center distance, etc., the meshing impact velocity is reduced. The ratio of impact velocity when meshing out to the engagement impact velocity when meshing in sits within a certain range. The gear design method that reduces the impact of the meshing pitch circle helps meet the low-noise requirements of the gear motor.
The smart drawer/cabinet lock gearbox is suitable for centralized control cabinets including lockers, letterboxes, storage cabinets, logistics cabinets, file cabinets, meter boxes, vending machines, mobile phone cabinets, shoe cabinets, etc. These kinds of gear motors are widely used in schools, community logistics, hotels, factories, bathing centers, banks, supermarkets and other places.
