Abstract
The invention relates to an extensible pedal. Defects that in the prior art, both ends of the pedal work non-synchronously and clamping stagnation appears due to the fact that the pedal utilizes a bi-directional driving linear extension are solved. The extensible pedal comprises the pedal and a driving mechanism which is arranged on a plane on which a pedal moving track lies or on a plane which is parallel to the plane on which the pedal moving track lies. The driving mechanism comprises two swinging arms and a following arm, wherein each end of the swing arm is connected on a support in a hinged mode, the following arm is connected with an end portion of the swinging arm. A drive motor is connected with one of the two swinging arms so that the swinging arm can become an actuating arm. The end portion of the following arm is connected with the pedal in a hinged mode, the length and a hinge position of the swinging arms guarantee that a rotation direction of the following arm is opposite to a rotation direction of the swinging arms. The planes of the driving mechanism and the pedal moving track are coplanar or parallel. The driving mechanism can convert the rotation of the drive motor into extensible movement of the pedal. The extensible pedal has a simple structure and can prevent the clamping stagnation of the operations.
