Abstract

The utility model relates to an automatically translational telescopic pedal which can move horizontally, has a simple structure, and runs smoothly. The shortcoming that two ends of the pedal are likely to run non-synchronously to result in stagnation as bidirectional driving is used by a pedal in the prior art to be telescopic linearly. The pedal telescopic mechanism comprises a pedal and driving mechanisms. The driving mechanisms comprise a frame, and rotary arms. The rotary arms are provided on the frame, are hinged with the frame via rotary shafts and can swing in a horizontal plane. The pedal is hinged on the rotary arm free end. Power units of the driving mechanisms are connected with the rotary arms. The horizontally swinging rotary arms are connected with the pedal. The rotary arms are driven to swing by the driving mechanisms, then the pedal is driven for translation and the pedal is telescopic at the bottom of an automobile. A sector gear is driven either by a worm rod or by a gear. The structure is simple and the driving is smooth. The two driving mechanisms are connected by a connecting rod to form a driving mechanism and a driven mechanism. Therefore, the translation of the pedal can be ensured to be smooth and phenomena of deflection and interference do not occur.
