    • A display unit and a vending machine having the same. The display unit includes a display panel to display an image, a circuit board to control the display panel, a board bracket installed at a rear of the display panel and formed with a receiving section to receive the circuit board, and a plurality of inlet holes and a plurality of outlet holes formed in opposite surfaces of the board bracket to allow external air to flow through the receiving section. The air travels through the inlet and outlet holes and passes through the receiving section in one direction to cool the display panel and the circuit board. Thus, the display unit is prevented from malfunctioning and the display panel is prevented from being degraded by heat even if tempered glass is installed at a front of the display panel.
    • 显示单元和具有该显示单元的自动售货机。 显示单元包括显示图像的显示面板,用于控制显示面板的电路板,安装在显示面板后部并形成有接收部分以接收电路板的板支架,以及多个入口孔 以及形成在所述板支架的相对表面中的多个出口孔,以允许外部空气流过所述接收部分。 空气通过入口孔和出口孔,并沿一个方向通过接收部分,以冷却显示面板和电路板。 因此,即使在显示面板的前方安装了钢化玻璃,也防止了显示单元的故障,并且防止了显示面板的热劣化。

    • A spring activated energy transducer is provided. The energy transducer of the current invention generates alternating current (A/C) electricity from abundant external natural forces. The energy transducer is comprised of an upper part and a lower part. The upper part is comprised of a housing, a helix metal spring, a first circular board, a second circular board with a short metal shaft, a ball bearing engaged to the short metal shaft, a third circular board with a groove to receive metal bearing balls, an upper metal shaft welded to the bottom of the third circular board, four arc-shaped springs welded to the bottom of the third circular board, and four sets of wheels rotatably attached to one end of the spring. The lower part is comprised of a housing, a lower metal shaft, a fourth circular board placed on the upper end of the lower part, bundles of electric wire, pluralities of permanent magnets, and a fifth circular board placed at the lower end of the lower part. As the helix metal spring is compressed by an external force, the bundle of electric wire turns between permanent magnets to produce electricity. Direction of the electricity alternates as the helix metal spring oscillates.
    • 提供弹簧激活的能量换能器。 本发明的能量换能器从丰富的外部自然力产生交流(A / C)电。 能量传感器由上部和下部组成。 上部由壳体,螺旋金属弹簧,第一圆板,具有短金属轴的第二圆板,与短金属轴接合的滚珠轴承组成,第三圆板具有槽,用于接纳金属轴承 焊接在第三圆板的底部的上金属轴,焊接在第三圆板底部的四个弧形弹簧,以及可旋转地安装在弹簧一端的四组轮。 下部包括壳体,下部金属轴,放置在下部的上端的第四圆形板,电线束,多个永久磁铁,以及放置在下侧的第五圆形板 较低的部分。 当螺旋金属弹簧被外力压缩时,电线束在永磁体之间转动以产生电力。 随着螺旋金属弹簧振荡,电的方向交替。
