Integration and Optimization of Geneva Mechanism in the Car Door Handle

The car door handle is an essential component of any vehicle, as it plays a crucial role in providing access to the cabin and ensuring safety of the passenger. The primary function of the car door handle is to allow entry and exit from the vehicle while preventing unauthorized access. In addition to this, car door handles also play a critical role in ensuring passenger safety by keeping the door closed during accidents or when there is a significant amount of G-force acting on the vehicle. A typical car door handle comprises several components including the structure, cover, bowden lever, bracket, pins and other child parts. The structure provides the ergonomics and rigidity for grabbing the handle, while the cover gives the handle an aesthetic appearance. The Bowden lever facilitates the unlatching of the door and the intermediate parts ensure that the handle operates smoothly. The position of the Bowden lever is crucial for the unlatching process and for keeping the door closed during the accidents and unauthorized entry. Therefore, design of the car door handle must work under optimize force to ensure that the handle performs it’s function effectively. The proposed design focuses on integrating the new mechanism that includes the Geneva drive concept. The mechanism aims to optimize the working of the car door handle while unlatching the door, thereby providing a safer and more efficient means of accessing the vehicle cabin. The proposed design with the Geneva wheel concept offers an innovative approach to optimize the force on the handle.
