Development and Exploration of Controlled Automated Scissors Car Jack for Vehicle Maintenance

Abstract

The scissors jack is a commonly used mechanical device for vehicle maintenance and other applications. However, its operation requires significant energy input, posing challenges and complexities, particularly for certain demographics. In response, this paper presents a novel approach to automate the scissors car jack, integrating it with an Android application to enhance energy efficiency, ease of operation, and safety. The motorized lifting system incorporates a car wiper DC motor with an internal gearing system to drive the lead screw of the scissors jack, enabling smooth upward and downward motions. An electrical circuit, comprising a microcontroller, voltage regulator crystal oscillator, diode, resistor, transistor, relay, and Bluetooth module was designed to power the motor through the vehicle's 12V cigarette port and control its rotational direction. Furthermore, an Android application, developed using the MIT App Inventor, serves as a remote control for the DC motor. Through this research, significant advancements in energy efficiency and operational convenience are achieved, while also ensuring enhanced safety during vehicle maintenance. The integration of the scissors jack with an Android application allows users to remotely control the lifting process, providing a more user-friendly and intuitive experience. The findings contribute to the fields of automotive technology, automation, and mechanical systems by offering an innovative solution for efficient and safe vehicle maintenance. In conclusion, this paper presents an automated scissors car jack system integrated with an Android application, showcasing improved energy efficiency, ease of use, and safety. The research findings provide valuable insights for practitioners and researchers alike, advancing knowledge and practice in the field of automotive maintenance and automation.
