Diseño y construcción de un mecanismo de asiento de copiloto giratorio eléctrico para personas con movilidad reducida, acoplado a una camioneta Mazda BT-50

Abstract

In this work was proposed the construction of a mechanism that can reduce the physical effort caused by people with reduced mobility when getting into or getting out of a vehicle. The needs of the users were taken into account for this construction, which was analyzed based on the quality rate, highlighting the priorities in terms of the requirements to facilitate access to the passenger seat of a Mazda BT-50 pickup. The use of ASTM A36 steel was demonstrated for the construction of the mechanism. Due to its properties, providing ease in terms of its weldability. Regarding the construction of the mechanism, it was designed in CAD software. Through the analysis of finite elements, the results of deformation and strain that the mechanism will support were obtained. This analysis is considered good based on its meshing and safety factor obtained. In the performance tests carried out, it was possible to show that the displacement and rotation movements commanded by the control installed in the mechanism are optimally generated inside the passenger compartment of the Mazda BT-50 truck, adapting to the different users who use the system mechanism. It is concluded that the mechanism is efficient in terms of its operation. However, there is a variation in speed of the movements carried out by the mechanism. Therefore, it is recommended to reduce its size as much as possible, as well as to take into account the use of better quality materials, and with less weight, engines with better characteristics in terms of power and strength so that the prototype provides better performance in terms of operation at the time of making its respective hook in vehicles such as sedans, pickups, etc.
