Assembly device for elastic part of electronic accelerator pedal

Abstract

The invention discloses an assembling device for an elastic piece of an electronic accelerator pedal. The setting of the limit bracket, the sliding limit connection structure between the upper end of the cover plate pressing module and the limit bracket, makes the distance between the cover plate pressing module and the swing arm support on the fixed base adjustable, which is convenient for spring The cover plate is inserted between the cover plate pressing module and the elastic piece, and the end of the elastic piece is inserted into the spring groove at the bottom end of the spring cover plate; the cover plate pressing module is slidably connected with the vertically arranged guide rod to keep the cover plate The press-fit module is vertically downward during the press-fit process to ensure that the spring cover and the swing arm support are matched with the latch holes of the two, so that the latch can be inserted smoothly.

Description

technical field [0001] The invention belongs to the technical field of assembling equipment for automobile electronic accelerator parts, and in particular relates to an assembling device for an elastic part of an electronic accelerator pedal. Background technique [0002] With the rapid development of the automobile industry, the mechanical accelerator pedal for automobiles has been gradually replaced by the electronic accelerator pedal. The electronic accelerator pedal precisely controls the opening of the throttle valve by outputting an electrical signal, thereby precisely controlling the combustion of fuel in the cylinder, making the energy efficiency ratio higher and the emission more environmentally friendly; widely used in passenger cars, buses, trucks, engineering vehicles, new energy cars, sedans and SUVs. [0003] The existing automobile electronic accelerator pedal includes parts such as swing arm, swing arm support, magnetic ring, sensor and elastic part, wherein...

AI Technical Summary

Problems solved by technology

[0003] The existing automotive electronic accelerator pedal includes swing arm, swing arm support, magnetic ring, sensor and elastic parts, among which, the elastic part is composed of two coaxial springs with different diameters, and the elastic part adopts Type press-fitting, that is, the opening on the side wall of the bracket, the elastic piece is loaded into the bracket from the opening in a direction perpendicular to its axis, one end of the elastic piece is in contact with the action end of the swing arm, and the other end of the elastic piece is in contact with the inner wall of the swing arm support. Butting against each other, this assembly method needs to place the elastic parts in a pre-tightened state, which is inconvenient for manual operation. The structure of the assembly device needs to be designed more complicated, and the setting of the side wall opening of the swing arm support results in the presence of elastic parts in the electronic accelerator pedal of the car. The defect of operation failure caused by falling out during use needs to be improved
