Drive System Functions in Smartwatch for Reliable Performance

2020-09-25 Shenzhen Zhaowei Machinery & Electronics Co. Ltd.

ZHAOWEI Drive is proud to announce a drive system with high torque and low speed, which functions in smartwatch for reliable performance. It opens new areas for a compact package with impressive torque capabilities without compromising on the smooth operation and long service life expected from ZHAOWEI.


Owing to the rising penetration rates of urbanization, the demand for aesthetically appealing advanced products with the ability to better serve the consumers’ requirements has been driving the demand for smartwatches globally. The smartwatch market is expected to grow at a CAGR of 14.5% during the forecast period (2020 - 2025). The global smartwatch market posted a healthy 20% revenue growth in H1 2020 despite the COVID-19 pandemic and shipments remaining flat compared to the same period last year, according to the latest research from Counterpoint’s IoT service.

However, smartwatches in the market are becoming more and more homogeneous, and many problems remain unresolved. In order to compete for the user market, some smartwatch manufacturers have also added camera systems to the wrist bands of smartwatches. Smartwatches enable guardians can not only locate and pay attention to the positions of the old and young, but also monitor their health and increase the interaction between family members via voice and video. The smartwatch with a camera will certainly bring great convenience to people's life. However, since the smartwatch is long exposed on the sleeve of the wrist, the hacker breaks the smartwatch defense system through the network for camera monitoring and control, threatening personal privacy security. On the other hand, lens wears seriously, reducingthe service life of the product. In addition, smartwatches need to integrate a variety of electronic components, batteries and sensors in a compact package, so the system integration level is relatively high and the requirements on component size and stability are more stringent.

ZHAOWEI Drive, together with smartwatch manufacturers, based on the humanized design and ZHAOWEI existing mature drive system, has designed an intelligent drive solution for smartwatches. Led by innovations, this forms a new product breakthrough, which lets the functions of watch and mobile phone closer.

Pushed by Under-Display Camera Technology and promising smart watch motor trend, ZHAOWEI has launched a smartwatch screen rotating solution. It tries to make the watch structure into a whole and integrate the camera system into the under-display body of the smartwatches. When users need to shoot or video with a wider angle, it is feasible to flip and rotate the smartwatch screen for greater vision. Besides, considering that those who prefer to use the watch as a camera may attach great importance to privacy security, ZHAOWEI has optimized the motorized camera lifting gear structure to suit the size of smartwatch. Thus, the camera no longer needs to be always exposed outside when not being used, convenient and safe.


In the limited internal space of smartwatches, ZHAOWEI uses 6mm planetary gearhead and stepper motor, adopts the design of parallel-axes gear drive and end bearing, and makes full use of the precision metal insert molding technology. Combined with the use of fixed frame, connecting plate as well as rotation axis, the drive structure proudly features small size, high torque and strong reliability. In this design, the rotation angle ofthe dial screen can be set according to the actual application of users, which improves the stability of bracket rotation and prolongs the service life of the smartwatch.


The smartwatch mainly consists of a processor, a low-power Bluetooth module, physical keys, a vibrating motor and an accelerometer used to detect gestures. In the limited stacked scaffold space of smartwatch, ZHAOWEI adopts stepper motor to provide power source and 4mm planetary gearbox with a small-module gear design to achieve high torque low rpm. The innovative insert-molding structure empowers a lightweight product and satisfies the needs that the lifting camera is hidden inside the watch for better privacy protection. This smooth operation enhances the service life of smartwatch with camera and reduces the wear and tear on the watch camera lens effectively.

As a smart wearable product with great imagination in 5G era, smartwatch is expected to enter the next level, whose application scenarios continue to expand. Upon request, ZHAOWEI can provide options for smart watch driver customization, available for partners needing tailored solutions.

“We are always providing high-quality, long-lasting & high-performance DC gear motorwhich is an ideal choice for smartwatches. As a reliable business partner, we are here to help the smartwatch manufacturers focus on user preferences and facilitate smartwatches to achieve intelligent upgrades in terms of gear drive systems,” said the Product Director of ZHAOWEI.
