Door Lock Gearbox Motors

Each Door Lock Gearbox Motors consists of a smart lock motor and a lock gearbox. By embedding the gearbox motor into the lock’s cylinder system, the unlocking process is complete. This improves the unlocking speed, as well as the safety of the door lock, while prolonging the lock’s tube system service life.

Smart Lock System

Background Information

With progressive developments in IT and wireless-communications technology, the concept of intelligent product existence resonates with the heart of individual users. An increasing demand in biometric door locks, and other smart lock systems have contributed to the intelligent security and home automation industries.

The Problem

Insufficient reliability, speed and security of smart home locks.

Product Description

In order to improve the security and reliability of smart door locks, ZHAOWEI has introduced the DC motorized door lock as a solution for the lock’s tube system, also known as smart door lock motor control system. It comprises of a micro smart lock motor and a precision lock gearbox, and contributes to the enhanced performance of each home’s smart door lock.

Smart Door Lock Gearbox

1. How do we improve unlocking speed? The ZHAOWEI smart door lock motor control system uses a DC motorized lock and a gearbox with a planetary structure to control the basic functions of locking and unlocking. This design makes basic locking more controllable, bringing more reliability, and enables a longer service life.

2. How do we then, improve lock security? The front panel of the ZHAOWEI smart door lock motor control system controls the locking bolt. The ZHAOWEI lock gearbox motor directly connects to the lock’s interior to form the rear control panel. Special security measures are placed to prevent anti-electromagnetic interference. This gearbox system has passed tests from a range of various levels of electromagnetic interference and failure analyses, resulting in high levels of anti-interference. The smart door lock also short circuits when intruders try to open these doors.

3. Lastly, how do we guarantee unlocking reliability? The micro gearbox uses different parameters for basic locking, utilizing multi-stage transmission, that changes from Stage 1 to Stage 4. The reduction ratio, stator speed and torque then adjusts according to the driving demand of the clutch motor in the lock’s body. This results in the ability to install smart gearboxes with compact structures, high efficiency, and high torque. There is no longer a need to face the awkwardness caused by door locks failing to open. 

The ZHAOWEI gearbox motor for smart locks used in this scheme has been tested and has shown great performance: It can withstand vibration, shock, and extreme temperatures, optimizing the performance/volume ratio (PVR). ZHAOWEI’s gearbox smart lock motor systems have passed tests for low noise, high dynamic performance, high power density, low energy consumption, high electromagnetic anti-interference, and long durability.
