In today of communications high development, increasing vehicle appears in the daily life, and automobile has become the vehicles of main flow; Continuous improvement, renewal, optimization at auto parts machinery become the inevitable of automobile industry.In car steering, the importance of throttle is self-evident.The development of present automatic field, throttle adopts electron type more, in the cohesive process of electronics and traditional mechanical, still has many technical matterss to exist, and these technical matterss greatly then have influence on running safety.
A magnetic control position transducer by name, the patent No. is the patent of invention of CN92239095.9, has disclosed a kind of sensor, is made up of magnet, magnetic conductor, Hall switch element and switch amplifying circuit.Magnet be installed in electric locomotive above or below, magnetic conductor is installed on the basis under the sky, tunnel or the track cross level, one or two Hall switch element of dress in the slit of magnetic conductor, its pin connects switch amplifying circuit.This transducer sensitivity height, reliable in action, can adapt to rugged surroundings.But its complicated in mechanical structure, precision is lower, temperature is floated shortcomings such as higher, that serviceable life is short, freedom from vibration is relatively poor.
Summary of the invention
The utility model mainly is at the existing in prior technology complicated in mechanical structure, serviceable life is short, precision is lower, temperature is floated the technical matters higher, that freedom from vibration is relatively poor etc., provide a kind of rational in infrastructure simple, serviceable life is short long, and precision is higher, temperature is floated lower, freedom from vibration programmable position sensor preferably.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: in described Hall element sensing unit is set, intelligent parts and interface unit, intelligent parts be by the I/O unit, the A/D unit, programmable read only memory, filter unit and computing unit are formed.
As preferably, described sensing unit adopts contactless design.Avoid friction during working sensor, can prolong the serviceable life of sensor.
As preferably, between described shell and rotating shaft, be provided with O-ring seal.
As preferably, be provided with magnet in described roller end, magnet is equipped with shading ring outward.Can prevent the interference of external magnetic field to internal magnetic field.
As preferably, be coated with metal level on the plug connector in the described interface unit.Make the signal transmission more stable.
As preferably, outside described rotating shaft, be with spring.After external force disappeared, spring can make rotating shaft be returned to initial position, and can be close to driving shaft, prevents signal jitter.
As preferably, described shell adopts totally-enclosed design, adopts ultrasonic soldering between shell and the cover plate.Can prevent entering of steam, increase the service life.
Therefore, the present invention has rational in infrastructure simple, and serviceable life is short long, and precision is higher, temperature is floated characteristics such as lower, that freedom from vibration is better.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: in Hall element 1 sensing unit is set, intelligent parts and interface unit, intelligent parts be by the I/O unit, the A/D unit, and programmable read only memory, filter unit and computing unit are formed; Sensing unit adopts contactless design; Friction when avoiding work can prolong serviceable life of sensor.Be provided with O-ring seal 4 between shell and the rotating shaft.Rotating shaft 2 ends are provided with magnet 3, the magnet 3 outer shading rings 4 that are equipped with; Can prevent the interference of external magnetic field to internal magnetic field.Be coated with metal level on the plug connector 6 in the interface unit.Make the signal transmission more stable.The rotating shaft 2 outer springs 7 that are with; After external force disappeared, spring 7 can make rotating shaft 2 be returned to initial position, and can be close to driving shaft 2, prevents signal jitter.Shell 8 adopts totally-enclosed design, adopts ultrasonic soldering between shell 8 and the cover plate; Can prevent entering of steam, increase the service life (as shown in Figure 1).
During work, the rotation of sensor rotating shaft 2, thereby drive the rotation of rotating shaft internal magnet 3, input signal is the geometry mechanical quantity of reflection angular displacement size, the variation of this mechanical quantity causes the variation of magnetic induction density, measure through Hall element 1, obtain and the linear voltage signal of induction level, or the pulse width modulating signal of output and the proportional relation of induction level.
