The model utility content
Technical problem to be solved in the utility model provides that a kind of simple in structure, with low cost, life of product is long, superior performance and the reliable motorcycle digital throttle position sensor of precision.
For solving the problems of the technologies described above, the utility model provides a kind of motorcycle digital throttle position sensor, comprise shell, be located at the end cap on the shell, be located at rotor, Hall element and magnet in the shell, be characterized in: magnet has a pair of, and an end of rotor is provided with and is used for the cruciate flower keyhole that links to each other with throttle plate pin, pair of magnet is alternate to be arranged on the cylindricality outer wall of the other end of rotor, and the sensitive surface of Hall element is relative with the cambered surface between the described pair of magnet.
Further, but in order on the sensitive surface of Hall element, to form a magnetic intensity generates corresponding linear change along with the variation of rotor rotation angle magnetic field, in the utility model: each magnet is that the cross section is the cylinder of fan annular, its polarity longitudinally both sides distributes, and this polarity to the adjacent side of magnet is provided with on the contrary on described rotor.
Further, for the sensing voltage signal output of the described Hall element that will reflect described rotor rotation angle and make this voltage of signals value between 0-5V, in the utility model: described shell is provided with three wiring terminals, and these three wiring terminals are respectively+DC electrical source end of incoming cables, grounding end and the feedback end of 5V; Described DC electrical source end of incoming cables is used to connect the power end of described Hall element, and described grounding end is used to connect the ground connection reference edge of described Hall element, and described feedback end is used to connect the sensing voltage signal output part of described Hall element.
Further, can active homing after rotation in order to make rotor, in the utility model: be provided with in the described shell and be used to control the Returnning spring that rotor resets.
The utlity model has positive effect: (1) motorcycle digital throttle position sensor of the present utility model is installed on the closure, its epitrochanterian cruciate flower keyhole links to each other with throttle plate pin, because of pair of magnet be embedded on the rotor be installed in shell on the induction point of Hall relative.Rotate closure, drive 90 ° of rotations of rotor, induce and the corresponding linear voltage of rotation angle.Because Hall element is very universal electronic product, the magnet technology is also very ripe, so the cost of this product is very low, simple in structure, with low cost, life of product long, superior performance and precision are reliable.(2) in rotor when rotation, drive pair of magnet and rotate together, and Hall element is fixing in the enclosure, so Hall element can be exported the correspondent voltage value by detecting on its sensitive surface the variation of magnetic intensity and direction, thereby realizes the function of position sensing.(3) motorcycle digital throttle position sensor of the present utility model is digital, and this position transducer is not friction in use, and the life-span is not subjected to the influence of external temperature more than the sensor height of simulation yet.
