Abstract
The invention relates to the field of electric vehicles, in particular to an application structure of a Hall element on a speed regulation signal input part of an electric vehicle. The Hall element with a special structure is used for replacing a potentiometer to regulate speed, so that the problems that the service life of the potentiometer for regulating the speed is short, potential unsafe factors exist, and the like are solved well. The inductive accelerator sensor comprises a substrate, a slide bar, magnets, a Hall element and a wiring board. A rectangular chute is formed on the substrate, the slide bar can move in the chute to and fro, a rectangular slot is formed on the surface of the slide bar, the magnets are arranged at two ends of the slot and move with the slide bar, a screwed hole is formed at one end of the slide bar and connected with a pedal slider mechanism, the Hall element is fixed on the wiring board and positioned between the two magnets, and electromotive force generated by the Hall element is led out by an electric wire on the wiring board and connected to a motor controller of the electric vehicle.
Description
Technical field
The present invention relates to electric automobiles, a kind of induction type throttle sensor of electric motor car particularly, promptly Hall element is in the application structure of electric motor car speed-regulating signal importation.
Background technology
The speed-regulating signal importation of traditional electrical motor-car is to drive moving of linear potentiometer by pedal through slider-crank mechanism, and the voltage signal of potentiometer output is delivered to the electric vehicle motor controller, realizes the adjusting to the driving motor of electric vehicle rotating speed.Because the potentiometer self structure, make its life-span and reliability receive certain limitation, when the slider loose contact of potentiometer or when breaking off fully, motor counter-rotating or other abnormal conditions then can appear.Even it is very low the possibility of this situation to occur,, just might produce very serious damage sequence in case this situation occurs.
Summary of the invention
In order to solve the not long and potential problems such as unsafe factor in serviceable life that the potentiometer speed governing exists, the present invention replaces potentiometer to carry out speed governing through the induction type throttle sensor that adopts Hall element to constitute, and has solved the problems referred to above well.
Induction type throttle sensor of the present invention comprises matrix, slide bar, magnet, Hall element and terminal block.Have the rectangle chute on the matrix, slide bar can move around in chute, and the slide bar surface has rectangular channel; Magnet is equipped with at the two ends of groove, moves with slide bar, and an end of slide bar has threaded hole; Be used for being connected with the pedal slide block mechanism, Hall element is fixed on the terminal block, between two blocks of magnet; The electromotive force that Hall element produces is drawn through the electric wire on the terminal block, is connected on the electric vehicle motor controller.
The invention has the beneficial effects as follows:
1, long service life
2, reliability is high
3, simple in structure, cost is low
4, assembly technology is simple, and it is convenient to use, change
Description of drawings
Further specify concrete characteristics of the present invention below in conjunction with Figure of description.
1 is matrix among Fig. 1, the 2nd, and slide bar, the 3rd, magnet, the 4th, Hall element, the 5th, terminal block, the 6th, screw.
Embodiment
The magnet 3 of in slide bar 2, packing into; Slide bar 2 is put into the chute of matrix 1 together with magnet 3, covers the terminal block 5 that Hall element 4 is housed, and with screw 6 terminal block 5 is fixed on the matrix 1; Matrix 1 is fixed in the electric motor car, and the threaded hole of slide bar 2 ends is connected with the pedal slide block mechanism of electric motor car.When pedal was depressed, slide block mechanism drove slide bar 2 and moves.Along with the variation of slide block 2 positions, the position of Hall element 4 in two blocks of magnet 3 changes, and the electromotive force of generation also changes, and just can realize the electric motor car speed governing operation according to the electromotive force of this variation through the electric machine controller of electric motor car.
