Diseño y construcción de un mecanismo bisagras tijera de accionamiento mecánico que permita el acceso a personas con discapacidad física en el automóvil Chevrolet.

Abstract

The current research work is about the design and construction of a scissors hinges mechanism through mechanic operation that allows the access to people with physical disability in a vehicle Chevrolet Suzuki forza 1. As an initial stage, it investigated the conditions and the operation, in which the mechanism of two plates connected and coupled by using bearings, bolts, and welding among them which were cut and in the vehicle. Through a blearing, they work as a mechanism of a vertical lifting for the vehicle door. The design proposes the anchoring of a shape plate in the structure of the vehicle, and the other plate is attached to the anchored plate making the role of a hinge in the form of scissors for vertical lift on the door. They system works with pneumatic and mechanical power, and pneumatic accessories to facilitate the hinge assembly in the vehicles, complying with technical specifications of construction and safety. To facilitate the handling of the vertical door opening system included a proper signage in the vehicle. In addition, it verified the good design and operation of each component of the scissor hinge by using computational tools in which the mechanical and functional conditions of the mechanism were tested. The design and simulation of the scissors hinge mechanism was carried out through solid work and ansys successfully, demonstrating that its construction has a high degree of reliability and safety talking into account that the cost of the hinges is economical and easy to access, handle and installation. They system can be incorporated in any type of vehicles in which the points of support and anchorage for the hinge are in good condition which allows helping people with physical disabilities to the easy accessibility to the vehicle and therefore mobility, improving their condition of life.
