    • A projector and a supporting structure thereof are provided. The projector includes a main body and a supporting structure. The supporting structure is disposed at the main body. The supporting structure includes a sliding element and an elastic element. The sliding element is supported on a plane and can move backward and forward with respect to the main body. The elastic element has a first end and a second end. The first end is coupled to the sliding element, and the second end is coupled to the main body. The elastic element generates a substantially constant elastic force when the elastic element is deformed. As the sliding element moves with respect to the main body, the elastic force balances against the gravity force of the main body, such that the elevational angle of the main body with respect to the plane is changed.
    • 提供投影仪及其支撑结构。 投影机包括主体和支撑结构。 支撑结构设置在主体上。 支撑结构包括滑动元件和弹性元件。 滑动元件支撑在平面上并且可相对于主体向后和向前移动。 弹性元件具有第一端和第二端。 第一端联接到滑动元件,并且第二端联接到主体。 当弹性元件变形时,弹性元件产生基本恒定的弹力。 当滑动元件相对于主体移动时,弹性力抵抗主体的重力平衡,使得主体相对于平面的仰角改变。
