Accelerator pedal for vehicle which has hysteresis
First Claim
1. An accelerator pedal for a vehicle, the accelerator pedal comprising:
- a housing;
a cylindrical hinge which is connected to the housing;
a main pedal arm which is coupled to one side of the hinge and rotates in a first direction in contact with a first action point of the one side of the hinge when a predetermined force is applied, wherein the first action point is located in a region within an outer circumference of the one side of the hinge in which friction occurs by contacting the main pedal arm and the hinge;
an auxiliary pedal arm which is coupled to another side of the hinge and rotates in a second direction in contact with a second action point of the other side of the hinge by an elastic force when the force applied to the main pedal arm is removed, wherein the second action point is located in a region within an outer circumference of the other side of the hinge in which friction occurs by contacting the auxiliary pedal arm and the hinge; and
a spring which is coupled to a bottom of one end of the auxiliary pedal arm and applies the elastic force to the auxiliary pedal arm;
wherein the main pedal arm comprises a receiving recess formed in a lower portion thereof fixed to the housing, and wherein the main pedal arm comprises through-holes to which the hinge is inserted and coupled and which are formed on both sides of the receiving recess; and
wherein the auxiliary pedal arm is inserted into the receiving recess, wherein an insertion recess to which the spring is inserted and coupled is formed in a lower portion of one end of the auxiliary pedal arm, and wherein a contact surface which has a predetermined curvature so as to come in contact with the outer circumference of the other side of the hinge is formed in an upper portion of the other end of the auxiliary pedal arm.

Abstract
An accelerator pedal for a vehicle, which has a hysteresis generation structure may be provided. The accelerator pedal for a vehicle includes: a housing; a cylindrical hinge which is connected to the housing; a main pedal arm which is coupled to one side of the hinge and rotates in a first direction in close contact with a first action point of the one side of the hinge when a predetermined force is applied; an auxiliary pedal arm which is coupled to the other side of the hinge and rotates in a second direction in close contact with a second action point of the other side of the hinge by an elastic force when the force applied to the main pedal arm is removed; and a spring which is coupled to a bottom of one end of the auxiliary pedal arm and applies the elastic force to the auxiliary pedal arm.
