Automotive Electric Door Limiter Smart Solution
Compact Design · High-Efficiency Drive · Intelligent Safety Control
As automotive intelligence and electrification accelerate, consumers are placing greater emphasis on comfort, convenience, and safety. Smart opening and closing systems—such as electric side doors and automatic tailgates—are becoming standard features in new vehicle models. As a key actuator component, the performance of the electric door limiter directly impacts the overall smart vehicle experience.
New Challenges in Smart Door Systems
Modern smart door systems must address several critical challenges:
·Compact integration requirements – Limited space within the door structure demands highly compact and modular drive units.
·High torque output needs – Heavier doors, especially when operating on inclines or uneven terrain, require stronger and more reliable torque performance.
·Enhanced safety and control – Features like anti-pinch, anti-collision, fast response, and stable operation are essential for a safe and intelligent door system.
ZHAOWEI’s Tailored Drive Solution
To meet these industry challenges, ZHAOWEI offers an intelligent electric door limiter solution that combines performance, reliability, and cost efficiency. Built upon our mature precision transmission development and manufacturing capabilities, the solution enables high-performance implementation of smart vehicle door systems.
Installed inside the door’s metal panel, the ZHAOWEI limiter features a compact structure for easy integration in limited spaces. Its core drive unit comprises a high-efficiency motor and precision gearbox, utilizing a worm-helical gear and lead screw-nut mechanism to achieve high torque output in a small footprint—providing strong, consistent power for door opening and closing operations.
Efficient · Stable · Safe
Upon receiving signals from the vehicle's Electronic Control Unit (ECU), the system responds quickly and executes commands with precision, ensuring smooth and controlled door movement. It supports quiet, reliable operation across various driving and environmental conditions.
Scalable for Multiple Models & Mass Production
Backed by ZHAOWEI’s vertically integrated R&D and manufacturing platform, the electric door limiter is highly customizable and scalable, enabling seamless adaptation across a wide range of vehicle platforms and body types. Its structure supports automated assembly and high-volume production, helping OEMs reduce development cycles and lower integration costs.
