Powered Retractable Running Board

11/25/2018: In Market Retractable Step Ladder Innovations

Vehicle retractable step latter designs have not really changed in the last decade with Aluminum or steel being the key material with standard high-power brushed motors. Carbon fiber & other green materials, Strong thermoplastic, brushless motors, wireless connectivity, proximity detect, and other features not considered. Lighting is a minor feature add and not really treated as functional must have with added potential benefits.

Amp Research seems to be the key patent holder for standard retractable running board designs.

ActionTrac™ powered running boards feature a patented step-within-a-step™ design — two steps in one and with no-splice wiring, no-drill bracket installation with powder-coated aluminum construction.

Two feature add powered / retractable running board in market now as shown below.

Automatic power side step with light, side step off road bar running board that utilizes an integrated LED light system, automatically extend when doors are open, and retract when doors are closed. Refer https://m.globalsources.com/gsol/I/Body-kit/p/sm/1160472063.htm to see unique lighting design.

Working with Innovators and Integrators Design HMI has completed production intent design concept for retractable running board with following key features:

1. 40% weight reduction.
2. Wireless power transfer eliminating wires or connectors.
3. Ambient White Light (4500K) for lighting both running board and road.
4. Lighting flows across running board with no visible hot spots.
5. Proximity Detect actuation.
6. Anti-Slip and Auto Defrost features.
7. Higher reliability brushless motor with smart electronics – 15% lower power.
8. Water Proof.
9. Additional feature investigates.

LED Lighting Feature Briefs

• LED light pedal is designed to increase the LED light unit on the side of the pedal, and can show different light effects through different signals on the car:
• Welcome and drop off passengers (changing lights): It greatly facilitates the convenience of passengers getting on and off at night;
• Flowing water: At the same time when steering or double flashing is turned on, the pedal will follow the turn signal to run water to increase the side warning when the car turns;
• 3, bonfire (lights back and forth): In the normal driving process, the pedal light will roll back and forth in the form of light segments to show the unique personality and unique look and feel of the vehicle.
