Protection device for preventing accelerator failure

Abstract

The invention discloses a protection device for preventing accelerator failure. The protection device for preventing accelerator failure comprises a grounding base, a plug connector, a first sensor, asecond sensor, a guide mechanism, a fixing sheet and a torsion spring; the first sensor and the second sensor are arranged at the bottom of the accelerator pedal; a second sensor is added on the basis of a single-path accelerator signal; the increased voltage range of the second sensor is twice of the voltage range of the first sensor; the voltage change curves are the same, the multiple relationis kept all the time in the accelerator pedal change process, the treading depth of the accelerator pedal is determined through a low voltage value, and therefore the vehicle speed is controlled, andthe advantages of protecting the vehicle and personal safety and eliminating potential safety hazards caused by the accelerator pedal are achieved.

Description

technical field [0001] The invention relates to the related field of electric multi-function vehicles, in particular to an anti-throttle failure protection device. Background technique [0002] The popularity of electric vehicles has also led to the development of electrification of multi-purpose vehicles, so electric multi-purpose vehicles are also constantly innovating. On this basis, the accelerator pedal used by many electric multi-purpose vehicles is a single-way accelerator pedal, which also leads to There are many security risks. [0003] In the current state, the accelerator signal of the vehicle is a single-channel voltage signal, and the vehicle determines the depth of the accelerator pedal by detecting the voltage change. In the state of running at full speed, potential safety hazards and personal safety accidents will occur, and when the accelerator pedal is in use, the wires will be pulled. Since the wires are generally placed randomly to fix the accelerator pe...

[0002] The popularity of electric vehicles has also led to the development of electrification of multi-purpose vehicles, so electric multi-purpose vehicles are also constantly innovating. On this basis, the accelerator pedal used by many electric multi-purpose vehicles is a single-way accelerator pedal, which also leads to many safety hazards

[0003] In the current state, the accelerator signal of the vehicle is a single-channel voltage signal, and the vehicle determines the depth of the accelerator pedal by detecting the voltage change. In the state of driving at full speed, there will be potential safety hazards and personal safety accidents, and when the accelerator pedal is in use, it will pull the wires. Since the wires are usually placed randomly to fix the accelerator pedal, the wires are worn and loose.
