Patent ID: 8701522

Claim:
An operation mode pendant type adjustment pedal apparatus comprising: an adjustment accelerator pedal including an accelerator pedal and an electric mode generating device, the accelerator pedal approaching or being separated from a driver by converting the rotation of a motor driven in accordance with a switch signal into linear movement, and the electric mode generating device achieving at least one mode where a reaction not using a pedal return spring is applied to the accelerator pedal in addition to a normal mode where a foot effort is applied to the accelerator pedal by the pedal return spring; an adjuster that supports the accelerator pedal and slides linearly; a lead screw that converts the rotation of the motor into linear movement in an axial direction by a worm engaged with a worm gear; a mounting housing that fixes the adjuster and the electric mode generating device, receives a load from the lead screw in the axial direction, is moved linearly, and moves the adjuster in the same direction; a sensor block communicating with the electric mode generating device and an ECU; wherein the pedal return spring is provided between the accelerator pedal and the electric mode generating device and is pressed and compressed by an upper end portion of the operated accelerator pedal about a hinge shaft of the accelerator pedal; and a load transmission unit that applies a force to the electric mode generating device through the upper end portion of the accelerator pedal and receives a force from the motor; wherein the electric mode generating device is a linear motor; wherein the load transmission unit includes; a load applying end that forms an upper end portion, which is positioned above the hinge shaft, of a pedal arm and is pushed through the pressing of a foot plate; and a load transmission rod that is fixed to the load applying end and transmits the movement of the load applying end to the electric mode generating device; wherein the pedal return spring is pressed by the load applying end and transmits a spring reaction to the pedal arm; wherein the adjuster includes: a slider that is fixed to the mounting housing without restricting the movement of the accelerator pedal, and includes a guider formed at a lower end of the slider, wherein a portion of the guider is combined with the accelerator pedal and at least one guide protrusion is formed at the guider; a guide block that guides sliding movement of the slider in a horizontal direction, the guide block including at least one guide channel formed at the guide block for guiding movement of the at least one guide protrusion formed at the guider, a return spring that applies an elastic return force to the slider; and an interlocking plate that is fixed to the return spring and moves together with the slider in the horizontal direction.
