In the most of vehicles, since this main function blocks the sunlight having an effect on the driver with one among the representative vehicle interior finish the driving stability of the driver is guaranteed and the sunvisor has the important function. Accordingly, the sunvisor is progressed by the research for guaranteeing the convenience of the driver and improvement in function with the quality enhancement of the vehicle interior finish.
In the existing research, it has the purpose in the functional improvement. And as to the research for the sunlight blocking improvement, that is the main function of the sunvisor, the research on the technology extending the area of the sunvisor is mainly progressed. However, the existing research is mainly limited in blocking the sun light in which the size extension of the sunvisor has an effect in the side and sunvisor existing blocking range.
In this research, the research for finding the blocking range appropriate after the mechanism design about the improvement of the sunvisor considering the driver sunlight blocking range was performed.
From this, by applying the mechanism theorical design which set the optimum range for up and down movement for the sunlight blocking of the sunvisor and pan and defined the maximum moving range of the sunvisor and uses the link mechanism, the pivot arm and sunvisor mechanism was designed.
The distance was compared based on the view maximum range of the results of the blocking range of the sunvisor applied the mechanism according to this design and existing sunvisor.
It could look at that sunlight blocking range of the sunvisor and operation range is altogether improved from this research result. The mechanism developed in this research be expected to be applied to the sunvisor design after this.
