Drive control performance Innovation

1. Achieving low power consumption with a quiescent current of less than 0.2mA at 13.8V

2. Adopting “BLDC+FOC” control to realize high load and low noise.

3. Using CANFD to connect with the car and achieve the function of instructing, diagnosing, and AutoSar network management.

4. Hover at any angle with anti-catch function.

Product innovation

1. Two in-place detection switches are added to the lock bolt to realize the judgment in different states of midway blocking and in-place blocking.

2. The product adopts the structure of double worm gear and distributed structure of power end and encoder detection end, which has the advantage of compact size, strong load performance, and high space utilization.

3. The damper and the input power end are designed at the same side, which achieves coaxial installation of the product and the screen backshell, as well as realizes the screen hovering at any angle.

Drive system for automotive
rotating & tilting display

With the design of “DC brushless motor + worm gear + parallel transmission”, ZHAOWEI’s drive system enables the automotive display to rotate up to 90°and tilt up to 15°, which realizes screen perspective switching and comfortable driving.

The product parameters can be customized
Drive system for
automotive roof monitor

ZHAOWEI’s roof monitor drive system adopts the design of worm gear with motor, using the propulsive force of the push rod and the gravity of the display to realize the opening and closing of the roof monitor and reduce the vibration noise caused by the poor concentricity of the transmission device. The product can work up to 20000 times and angular deviation within 0.5°

The product parameters can be customized
Drive system for
automotive tilting display

The product is composed of DC brushless motor, lift coupling, gearbox, PCBA, and connection bracket, which realizes the automotive display lifting by linear actuator motion. Through single head worm gear self-locking structure and mechanical limit, the gap between gears can be eliminated.

The product parameters can be customized
Drive system for
automotive display camera

The automotive display camera drive system is similar to the phone pop-up camera, which adopts the design of stepper motor with gearbox. The lifting module is driven by a stepper motor to move the metal module up and down, which enables the camera to lift stably with low noise.
