Automatic Retractable Steps

-- Steady & Reliable Manufacturer --

Mechanism and Functionality

These automatic retractable steps utilize a dual-motor, synchronous drive system integrated within the vehicle's chassis structure. The activation is linked directly to the door sensor circuit, initiating deployment within 0.8 seconds upon door opening. The system maintains a low-profile, tucked-in position when the doors are closed, preserving the vehicle's aerodynamic profile and ground clearance. Each step assembly is designed for smooth, consistent motion through precision-cut internal gears and sealed bearing systems, guaranteeing reliable performance across high-cycle operations.

Safety is managed by an integrated anti-pinch sensor. If an obstruction is detected during retraction or deployment, the system immediately halts and reverses motion, preventing damage to the mechanism or injury to users. The steps are calibrated to deploy only when the vehicle is stationary and the transmission is in Park (P) or Neutral (N), depending on the model's CAN-bus integration.

Introduction to Automatic Step Technology

The shift towards advanced vehicle access solutions has driven the development of automatic retractable steps. This technology provides seamless, secure entry and exit for SUVs without permanently altering the vehicle's aesthetics or performance characteristics.

Our company, established in 2014, specializes in the R&D and manufacturing of medium to high-end SUV electric pedals. Located in Huzhou City, Zhejiang, a key industrial hub in the Yangtze River Delta, our proximity to major global ports like Shanghai and Ningbo streamlines logistics. We focus on technological innovation, utilizing advanced facilities including intelligent automatic CNC machining centers and a dedicated full performance testing center to ensure every step solution meets stringent international standards.

FAQ: Automatic Retractable Step Solutions

Q: How does the anti-pinch safety feature function?
A: The integrated smart control unit monitors the current drawn by the motor during operation. If the current spike indicates resistance (e.g., from an obstruction), the system instantly stops and reverses the motion. This prevents excessive force from being applied to the step or the obstruction.

Q: What happens if the steps are deployed in heavy snow or ice?
A: Our system uses high-torque motors and thermal overload protection. While thick ice may temporarily prevent deployment, the system is designed to detect high resistance and prevent motor burnout. For optimal performance in severe weather, routine cleaning of the moving parts is recommended.

Q: Is complex electrical wiring required for installation?
A: No. Our designs prioritize a "plug-and-play" installation philosophy, minimizing the need for cutting or splicing original vehicle wiring. The kits include model-specific wiring harnesses that connect directly to existing vehicle access points, facilitating efficient installation by service professionals.

Operational Reliability and Design Integrity

Integrated Vehicle Protocol: Steps are designed for seamless CAN-bus or OBD integration where required, ensuring error-free communication with the vehicle's electronic systems.
IP67 Rated Motors and Wiring: All electronic and moving parts are sealed against dust ingress and immersion in water up to 1 meter, crucial for all-weather durability.
Ground Clearance Preservation: The fully retracted design ensures no significant reduction in the vehicle's approach, departure, or breakover angles.
Anti-Corrosion Finish: Frame components are treated with a multi-layer powder coating, providing extended resistance against road salt, moisture, and debris.

Engineering for High-Volume OEM/ODM

Our manufacturing facility is structured around the capacity to deliver 80,000 sets of electric pedals annually, managed through an integrated ERP system that controls the internal production management process.

Design Validation & Prototyping: Utilizing in-house 3D scanning and CAD/CAM software to ensure precise fitment to target vehicle chassis without structural modification. Prototypes undergo rigorous fitment and stress testing prior to batch production.
Customization Scope: We offer customization in Step Length, Surface Pattern/Finish, and LED Integration (color/intensity) to meet specific regional market demands or branded accessory lines. All components are manufactured using our intelligent automatic CNC machining centers to maintain exact tolerances.
Logistics & Supply Chain: Our established location and "ready to ship" inventory protocols, combined with streamlined internal processes, support predictable lead times for international bulk and container-load orders.

Material Selection for Durability and Aesthetics

The material composite for automatic steps must balance structural strength with weight efficiency and corrosion resistance.

Step Plate: Utilizes 6061 T6 Aluminum Alloy for its strength-to-weight ratio and resistance to environmental fatigue. The surface is often finished with a structured, non-slip texture molded from UV-stabilized, heavy-duty engineering plastic (ABS/PC composite).
Brackets and Mechanism Frame: High-gauge, cold-rolled Q235 or Q345 Structural Steel is used for mounting points to ensure maximum load bearing. These components undergo a precise E-coating process followed by a double-layer powder coat finish to protect against road salt and moisture exposure.
Motor Housing: Sealed Die-Cast Aluminum casing provides efficient heat dissipation and protection for the motor and gear mechanism from external contaminants (IP67 standard).
