Automated Seatbelt Restraint - SSW

Controls Enclosure

Overview:

This project introduces an innovative Control Box designed to enhance passenger comfort and safety through a state-of-the-art seatbelt adjustment system. Leveraging cutting-edge technology, this system offers seamless communication, precise motion control, and an intuitive interface for effortless adjustments by passengers.

Components & Features:

This project introduces an innovative seatbelt adjustment control system designed to enhance passenger comfort and safety. It leverages an HC-05 Bluetooth module for wireless communication via the MIT Inventor App, and a Teensy 4.1 microcontroller for precise motion control, complemented by a Nextion 3.5'' HMI display for an intuitive user interface. The system is powered by a 12V 3A supply, with a 24V fan ensuring optimal cooling, and features two industrial motion motors with linear guides for smooth seatbelt adjustments.

This project features the design and development of a preliminary PCB board sketch aimed at interfacing all hardware components used in an advanced seatbelt adjustment control system. As a demo project, it serves as a practical learning exercise to delve deeper into the intricacies of two-layer PCB design. While this initial sketch is a rough approximation, it successfully outlines the necessary connections for the Teensy 4.1 microcontroller, Nextion 3.5'' HMI display, and additional components such as a 12V 3A power supply and a 24V cooling fan.

Drive Train Design

Incorporating a NEMA23 stepper motor into the drive train design of this application is a strategic decision, particularly for industrial motion control contexts, due to several key reasons related to the motor's specifications and compatibility with demanding environments.

In conclusion, the decision to use a NEMA23 stepper motor in this drive train design is informed by the need for a motor that offers a blend of power, precision, and durability, making it an ideal choice for the rigorous demands of industrial motion control.

Structural Frame Design

The structural frame outlined in this preliminary design serves as the foundational component of the final system, focusing on demonstrating the user restraint mechanism. Although this initial design does not detail wiring routing or the complete system integration, it provides a conceptual overview of how the user will be securely restrained, which is a critical aspect of the project's safety and functionality.

The linear drive train design is running at about 75% Maximum Speed, where the user can adjust the speed control based on their personal preference and this video is with the intentional purpose to demonstrate the smooth transitioning of the linear drive train.
