Non-contact type hand and foot integrated waterproof electronic throttle

Abstract

The invention discloses a non-contact type hand and foot integrated waterproof electronic throttle. The non-contact type hand and foot integrated waterproof electronic throttle comprises a base, a pedal, a position rocker, a sealing circuit box, a spring, a position detection input circuit and a sensor control circuit; the position detection input circuit comprises magnetic steel and a Hall element array, the magnetic steel is arranged on a short arm of the position rocker, and the Hall element array and the sensor control circuit are arranged in the sealing circuit box through a circuit board; when the pedal is at the initial position, the short arm of the position rocker is at the highest position, the magnetic steel faces a first Hall element at the upper end of the Hall element array in the sealing circuit box, the Hall element inputs a pedal position signal to the sensor control circuit, and the pedal position signal is processed by the sensor control circuit and is outwards output to serve as a throttle signal at idle; and when the pedal is stepped, the magnetic steel on the short arm of the position rocker faces a Hall element at the corresponding position in the sealing circuit box along with changes of the position of the pedal, the sensor control circuit collects data of the Hall element array, and the data are processed to be outwards output to serve as throttle signals at the pedal position.

Description

technical field [0001] The invention relates to a non-contact hand and foot integrated waterproof electronic accelerator for automobiles and tractors. Background technique [0002] At present, the non-contact electronic throttle used on automobiles or tractors mainly adopts the principle of photoelectricity, electromagnetic or Hall. The sensor signal source is driven to move by stepping on the accelerator pedal, and the corresponding pedal position signal is generated by the corresponding sensor sensor, which is controlled by the sensor. The circuit processes and outputs an accelerator pedal position signal to the outside. The existing non-contact electronic accelerator, because the accelerator pedal is used to drive the sensor signal source to move through the rotating shaft, the long-term use will cause the wear of the rotating shaft pair, and there is no isolation seal between the sensor signal source and the sensor sensing body. In harsh environments, especially When th...
