Electric window of railway locomotive
The invention relates to an electric window of a railway locomotive. The electric window comprises a fixed frame, a movable frame connected into the fixed frame in a sliding mode, a self-balancing mechanism and a driving mechanism. The self-balancing mechanism comprises a fixed frame, a transmission part and a telescopic part, and the fixed frame is fixedly installed in the fixed frame and located below the movable frame; the telescopic part is used for absorbing gravity of the movable frame; the driving mechanism comprises a synchronous belt wheel set and a stepping motor, synchronous wheels of the synchronous belt wheel set are rotationally connected to the fixed frame, synchronous belts of the synchronous belt wheel set are fixedly connected with the movable frame, and the stepping motor is used for driving the synchronous wheels of the synchronous belt wheel set to rotate so as to drive the movable frame to ascend and descend. The combination of the stepping motor and the synchronous pulley set can improve the reliability of driving the electric window to ascend and descend, the hovering of the movable frame at different positions is more accurately realized, and the use reliability is improved. When the movable frame ascends or descends, the transmission piece converts displacement in the vertical direction into transverse swing, kinetic energy is absorbed through the telescopic piece, and hovering of the movable frame can also be achieved when power is off.
本申请涉及一种铁路机车电动窗，包括固定框、滑动连接于固定框内的活动框、自平衡机构和驱动机构；自平衡机构包括固定架、传动件和伸缩件，固定架固定安装在固定框内且位于活动框下方；伸缩件用于吸收活动框的重力；驱动机构包括同步带轮组和步进马达，同步带轮组的同步轮转动连接于固定框，同步带轮组的同步带与活动框固定连接，步进马达用于驱动同步带轮组的同步轮转动进而驱动活动框升降。步进马达与同步带轮组相结合能够提高驱动电动窗升降的可靠性，更加精准实现活动框不同位置上的悬停，提高使用可靠性。当活动框上升或下降时，传动件将竖直方向的位移转换为横向摆动，并通过伸缩件吸收动能，当断电时，也能实现活动框的悬停。
