摘　　要：为了解决ATM存取款机闸门装置成本高、传动和自锁结构复杂、可靠性不足等问题,创新设计了一款摆臂传动升降的闸门。该闸门利用曲柄滑块原理,以直流有刷电机驱动摆臂转动,摆臂末端的滚动轴承在闸门板的滑道上滚动,致使闸门在上下方向的滑套内上下移动,实现闸门的打开和关闭。通过利用曲柄具有的自锁点,匹配限位件设计,解决闸门自锁功能;通过杠杆原理,巧妙设计微动开关与压杆的位置,解决闸门的防夹手安全问题。相较于现有技术利用齿轮齿条或传送带传动、电磁铁解锁的闸门方式而言,本方案仅采用了曲柄摆臂滑块传动、曲柄自锁和杠杆防夹手,传动结构更巧妙简单,成本更低,可靠性更高。通过分析、测试验证,该结构方案稳定可靠,能满足50万次的寿命测试,为ATM存取款机的安全、高效运行提供了有力保障。In order to solve the problems of high cost,complex transmission and self-locking structure,and insufficient reliability of the ATM cash dispenser gate device,an innovative design of a swing arm drive lifting gate is developed.The gate uses the principle of a crank slider to drive the swing arm rotation with a DC brush motor.The rolling bearing at the end of the swing arm rolls on the slide of the gate plate,causing the gate to move up and down within the sliding sleeve in the up-down direction,achieving the opening and closing of the gate.By utilizing the self-locking point of the crank and matching the design of the limit stop,the self-locking function of the gate is solved.Through the lever principle,the position of the microswitch and pressure bar is cleverly designed to solve the safety problem of anti-pinch of the gate.Compared to existing technologies using gear rack or conveyor belt transmission,electromagnet unlocking gate methods,this solution only uses the crank slider transmission,crank self-locking,and lever anti-pinch,with a more ingenious and simple transmission structure,lower cost,and higher reliability.Through analysis,testing,and verification,this structural solution is stable and reliable,able to meet a life test of 500,000 times,providing a strong guarantee for the safe and efficient operation of ATM cash dispensers.
