Accelerator pedal lever for new energy vehicle based on magnetorheological fluid principle

Abstract

An accelerator foot bar for a new energy vehicle based on a magnetorheological fluid principle relates to the technical field of mechanical equipment in the field of new energy, and comprises a rotating shaft, clamping grooves which are uniformly distributed are formed in the inner side of the rotating shaft, and a foot bar is rotatably connected to the middle of the rotating shaft; the middle of the foot bar is fixedly connected with a first electromagnet, evenly-distributed piston grooves are formed in the outer side of the foot bar, and the inner walls of the piston grooves are fixedly connected with first springs. According to the accelerator foot bar for a new energy vehicle based on the magnetorheological fluid principle, through cooperative use of the first electromagnet and the second electromagnet, when the pedal rod is normally used, the electromagnet I and the electromagnet II are electrified at the moment, so that the viscosity of magneto-rheological fluid in a piston groove is increased, a clamping block cannot be retracted into the pedal rod, and the pedal rod and a rotating shaft are relatively fixed; when the pedal rod is treaded in emergency, the first electromagnet and the second electromagnet are both powered off, the clamping block can be conveniently contracted into the foot bar, and therefore the effect of preventing mistaken stepping is effectively achieved, and the safety of the new energy vehicle is improved.

Description

Technical field[0001]The present invention relates to the technical field of new energy fields, in particular, a new energy vehicle throttle pedal pedal based on magneto-fluid fluid principles.Background technique[0002]Today, human beings have once again come to the crossroads of the transportation energy power system change. The third change will be in replacing oil and internal combustion engines with electricity and power batteries, bringing human beings into the clean energy era, our bold forecast, the third traffic energy motivation The system's change will drive the Asian economy soon, so that Asia's replacement of the United States has become an engine of the world economy. The current new energy vehicle often has some problems affecting normal use, there is a certain safety hazard.[0003]At present, the current new energy vehicle throttle is in use, mostly fetched downwards, turn the throttle pedal, so that the car accelerates, but when encountering an emergency, it often occ...

Problems solved by technology

[0002] Today, mankind is once again at the crossroads of the transformation of the transportation energy power system. The third transformation will replace petroleum and internal combustion engines with electricity and power batteries, bringing mankind into the era of clean energy. Our bold prediction is that the third transportation energy power The change of the system will drive the Asian economy to take off, and make Asia replace the United States as the engine of the world economy. The current new energy vehicles often have some problems in the use process that affect the normal use, and there are certain safety hazards

[0003] At present, when the accelerator pedal of new energy vehicles is in use, most of the accelerator pedals are stepped down by the foot to rotate the accelerator pedal to accelerate the car. The vehicle will accelerate suddenly, causing traffic accidents, seriously threatening personal safety, and causing serious property damage.
