The invention discloses a telescopic pedal device. A threshold is arranged at the upper part of a pedal frame, a cover plate is mounted at the top of the pedal frame, a driving motor is arranged in the pedal frame and drives a movable pedal in a telescopic device to stretch out and draw back, and a locking isolation assembly is arranged in the pedal frame; and the locking isolation assembly is locked with a lock catch on the movable pedal. A synchronous belt or chain tensioning device and a front bearing guide assembly are installed below the movable pedal, the structure is compact, and the occupied space is small; the pedal is doubly locked through a motor brake and a mechanical latch hook after being retracted, and is safer and more reliable; the pedal isolation lock can perform isolation operation only after the pedal is retracted, so that the pedal isolation lock has a misoperation prevention function; pedal isolation and unlocking are operated by a steel wire rope, and a lock cylinder operating device is prevented from being arranged on the upper cover plate; a pedal motor unlocking assembly is unlocked by adopting a rotatable bracket; and the pedal cover plate is good in sealing performance, and the interior of the pedal can be overhauled and maintained conveniently.

    本发明公开了一种伸缩踏板装置,所述踏板框架上方设置有门槛,盖板安装于踏板框架顶部,踏板框架内设置有驱动电机,驱动电机带动伸缩装置内部活动踏板伸缩,踏板框架内设置有锁闭隔离组件,锁闭隔离组件与活动踏板上的锁扣相锁闭。本发明同步带或链条张紧装置及前部承载导向组件安装于活动踏板下方,结构紧凑,占用空间小;踏板收回后通过电机制动器和机械锁钩双重锁闭,更加安全可靠;踏板隔离锁只有在踏板收回后才能进行隔离操作,具有防止误操作功能;踏板隔离和解锁均由钢丝绳操作,避免在上部盖板上设置锁芯操作装置;踏板电机解锁组件采用可旋转支架进行解锁;踏板盖板密封性能好,方便对踏板内部进行检修维护。
