    摘要： This invention pertains to an attachment to an electric wheelchair. The attachment enables an electric wheelchair to be used in areas that would not otherwise be possible. An electric wheelchair, though very useful and necessary, has several mobility drawbacks. Off road areas such as beaches, mud, and even tall grass pose a problem to the electric wheelchair. This invention provides an attachment to an existing electric wheelchair and powered off of that wheelchair's motor that allows the user to explore terrain that would not be possible in conventional wheelchair designs. By designing a drive system that works off of the electric wheelchair's power, the attachment can remain purely mechanical. With no motors or electric parts on the attachment, the design is simple and user friendly.

    摘要翻译： 本发明涉及电动轮椅的附件。 附件使得电动轮椅可以用于不可能的区域。 电动轮椅虽然非常有用和必要，但具有几个移动性缺陷。 诸如海滩，泥土，甚至高大的草地之类的道路区域对电动轮椅构成问题。 本发明提供了一种与现有的电动轮椅的连接，并且该轮椅电动机被关闭，这允许用户在常规轮椅设计中探索不可能的地形。 通过设计一种可以减轻电动轮椅动力的驱动系统，附件可以保持纯机械性。 附件上没有电机或电气部件，设计简单，用户友好。
