A swing-arm type electric pedal for automobile

Abstract

The invention belongs to the technical field of automobile pedals, and particularly relates to an automobile swing-arm type electric pedal. One end of a main swinging support arm is rotatably connected with a main rocker support frame, and can rotate relative to the main rocker support frame around a first fixed shaft; and the other end of the main swinging support arm is rotatably connected with a step tread, and can rotate relative to the step tread around a first moving shaft. One end of an auxiliary swinging support frame is rotatably connected with an auxiliary rocker support frame, and can rotate relative to the auxiliary rocker support frame around a second fixed shaft; and the other end of the auxiliary swinging support frame is rotatably connected with the step tread, and can rotate relative to the step tread around a second moving shaft. A driving motor for driving the main swinging support arm to rotate around the first fixed shaft is mounted on the main rocker support frame. According to the automobile swing-arm type electric pedal, the structure is simple, the torsion output loss of the motor is also less, and therefore a smaller motor can be selected; rational positions for placing support frames are easy to find in limited vehicle bottom design space; and main parts of the motor are wrapped by the main rocker support frame, so that the security and service life of the motor are improved, and cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile pedals, and more particularly relates to an automobile swing arm type electric pedal. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] Vehicle steps are divided into fixed steps and zoom-type steps. As the name suggests, fixed steps cannot realize the zoom function of the steps. , can realize the function of step retraction in non-use state and step expansion in use state. When the pedals can be retracted, they are located at the lower end of the side of the vehicle body and will not protrude from the outside of the vehicle body. Therefore, when the vehicle passes through a narrow road section, the pedals will not collide with obstacles to avoid damage to the pedals. [0004] Scalable pedals usually extend the pedals horizontally...

AI Technical Summary

Problems solved by technology

[0005] 1. The pedal structure is more complicated, and the processing and manufacturing costs are higher;

[0006] 2. The torque output loss of the pedal retractable motor is relatively large, which requires a large motor, which is not conducive to cost control and installation space selection;

[0007] 3. After being folded, the volume is large and difficult to place;

[0008] 4. The position of the motor is not easy to hide, easy to expose, easy to be damaged by external force
