The invention discloses an automatic folding and unfolding boarding ladder which comprises multiple stages of pedals, a ladder frame at the two sides of the pedals, a synchronous opening and closing mechanism, a driving mechanism, a pair of ladder frame storage locking mechanisms and a boarding ladder storage side cabin. The ladder frame includes multiple transmission parallelogram frames hinged in a stepped mode. The synchronous opening and closing mechanism is arranged at the two sides of the upper portion of the ladder frame and comprises a pair of meshed half gears, a half gear shaft and apair of half gear connecting plates, and the other end of the driving mechanism is hinged to the lower corner of the boarding ladder storage side cabin. The boarding ladder storage side cabin is fixed under one side of a vehicle platform. The boarding ladder is wide in application range, rapid and automatic unfolding and rapid and automatic folding and unfolding of the device are achieved throughthe superposition effect of multiple parallelogram connecting rod mechanisms, the boarding ladder is convenient and rapid to use and high in automation degree, the labor intensity of operators is greatly reduced, the working efficiency is improved, and the getting-on and getting-off safety of the operators is guaranteed.

    本发明公开了一种自动收放登舱梯,包括多级踏板、踏板两侧的梯架、同步开合机构、驱动机构、一对梯架收纳锁定机构和登舱梯收纳边舱,梯架为多个成梯级铰接的传动平行四边形框架。同步开合机构设置在梯架的上部两侧,包括一对啮合的半齿轮、半齿轮轴和一对半齿轮的连接板,驱动机构另一端与登舱梯收纳边舱一下角铰接。登舱梯收纳边舱固定在车辆平台的一侧下。本发明适用范围广,通过多个平行四边形连杆机构的叠加作用,实现了本发明的快速自动展开和快速自动折叠收回,方便快捷、自动化程度高,大大降低了操作人员的劳动强度,提高了工作效率,确保人员的上下车安全。
