The invention provides an accelerator pedal structure. The accelerator pedal structure comprises a first supporting seat, a second supporting seat, a fixing arm fixedly connected with a pedal and an installing seat connected with a car body. The first supporting seat is provided with a first installing part which is rotatably connected with the lower end of the installing seat. One side, close to the first installing part, of the first supporting seat is fixedly connected with the other end of the fixing arm. One side, far away from the first installing part, of the first supporting seat is rotatably connected with the lower end of a connecting part. The second supporting seat is provided with a second installing part rotatably connected with the upper end of the installing seat. One side, close to the second installing part, of the second supporting seat is rotatably connected with the upper end of the connecting part. One side, far away from the second installing part, of the second supporting seat is connected with an accelerator drawing wire. The second supporting seat is provided with a return device. According to the accelerator pedal structure, the movement space of the pedal is small, and the acceleration time of a car is short.
