Electric Running Boards for SUVs

-- Steady & Reliable Manufacturer --

Product Description

The Electric Running Board system is an automatically deployable entry/exit aid designed for SUVs, Crossovers, and light trucks. It consists of a pair of motor-driven steps that remain retracted and flush with the vehicle's rocker panel during driving to preserve aerodynamic efficiency and aesthetics. Upon opening a door, the system activates, extending the steps to a predetermined, ergonomically optimized position to facilitate easy and safe ingress and egress. When the doors are closed, the steps automatically retract.

The system integrates directly with the vehicle's CAN bus or door trigger signals, ensuring synchronization with the vehicle's locking/unlocking status. The core assembly includes high-torque, low-noise DC motors, a robust linkage mechanism, precision-machined aluminum alloy steps with anti-slip surfaces, and a dedicated electronic control unit (ECU) with built-in safety logic.

Technical Deep Dive

The ECU employs multiple sensor inputs, including door status, vehicle speed, and gear position, to make deployment decisions. An intelligent anti-pinch mechanism uses current monitoring to reverse direction if an obstruction is detected. The housing is rated at IP67, protecting internal components from water and dust ingress in harsh driving conditions. The system's operational cycle life exceeds 30,000 cycles, validated through extensive endurance testing at our facility in Huzhou.

Primary Applications

Passenger SUVs & Crossovers: Ideal for family-oriented vehicles (e.g., Audi Q7, BMW X5, Mercedes-Benz GLE) where ease of entry for children, elderly passengers, or shorter individuals is a priority.
Lifted or Modified Vehicles: A practical necessity for trucks and SUVs that have undergone suspension lifts, increasing the step-in height significantly.
Premium & Luxury Segment: Enhances the ownership experience by adding a layer of convenience and a distinctive visual signature upon entry/exit.

Secondary & Commercial Use

Fleet & Commercial Vans: Suitable for long-wheelbase vehicles like the Mercedes-Benz V-Class, aiding drivers and passengers in frequent entry/exit scenarios.
Aftermarket Retail: Serves automotive accessory shops, customization centers, and dealerships as a high-value add-on product.
OEM/ODM Collaboration: Provides integrated entry solution packages for vehicle manufacturers or major tier-1 suppliers.

Q: How is the system powered and connected?
A: It connects directly to the vehicle's 12V battery through a dedicated, fused harness. The trigger signal is typically taken from the door lock circuit or CAN bus network, ensuring seamless integration.

Q: Will installation affect my vehicle's warranty?
A: Professional installation that does not cut factory wiring harnesses generally does not void the overall vehicle warranty. However, it's advisable to consult your vehicle manufacturer's policy. We provide detailed, non-invasive installation guides.

Q: Can I operate the steps manually if the power fails?
A: Yes. A manual override mechanism is built into the motor assembly. Using the provided tool, you can manually extend or retract the steps in case of a complete power loss.

Q: Are these suitable for off-road use?
A: With an IP67 rating on critical components, the system is resistant to water and dust. However, for extreme rock crawling or deep water fording, consulting specific off-road installation precautions is recommended to protect brackets and wiring.

Key Advantages

Vehicle-Integrated Logic: Synchronizes with door locks and vehicle speed, preventing deployment while driving for safety and legality.
Robust Construction for Durability: The use of aluminum alloy for the step and linkage, combined with IP67-rated components, ensures long-term reliability in diverse weather and road conditions.
Safety-First Design: Incorporates an anti-pinch reversal feature and a manual override function accessible via a dedicated tool for emergency situations.
Aerodynamic & Aesthetic Preservation: Retracted profile maintains the vehicle's original body lines and minimizes wind resistance and noise.

Engineering Core

Precision Movement: Engineered linkage provides stable, wobble-free extension and retraction, even under load.
Optimized Installation: Vehicle-specific mounting brackets are designed to utilize factory holes where possible, minimizing invasive modifications.
Low Noise Operation: Optimized gear train and motor mounting reduce operational sound to below 50 dB during normal use.

Production Capacity

Our facility operates with an annual output capacity of 80,000 sets. Production flow is managed via an ERP system, encompassing SMT for ECU assembly, automated CNC machining for brackets and steps, robotic welding and painting lines, and a final assembly/testing station. Each batch undergoes sampling tests for load, cycle life, and weather resistance.

Material Selection Overview

The choice of materials directly impacts performance, longevity, and aesthetics. Our standard configuration is engineered for an optimal balance.

Step Panel (Primary): 6063-T5 Aluminum Alloy
Selected for its excellent strength-to-weight ratio, corrosion resistance, and extrudability, which allows for complex cross-sectional profiles that are both rigid and lightweight. The T5 temper provides good mechanical properties.
Surface Finish Options:
- Textured Powder Coating: Standard finish. Offers a uniform, durable layer resistant to chipping, UV fading, and chemicals. Provides a consistent grip.
- Stainless Steel Insert: Optional. A brushed stainless steel panel embedded into the aluminum step for a premium, bright appearance. Requires more care to avoid scratches.
- Anti-Slip Rubber Insert: Optional. Provides maximum traction in all weather conditions, particularly for utilitarian or family vehicles.
Linkage & Brackets: Q235 Steel or 5052 Aluminum
Structural brackets are typically made from powder-coated carbon steel (Q235) for strength and cost-effectiveness. For weight-sensitive applications, brackets can be fabricated from 5052 marine-grade aluminum.
