Abstract
The utility model discloses a throttle valve position sensor which is characterized by comprising a shell, a rotor, magnetic steel, a torsion spring and a circuit board. A cavity of the shell is divided into an upper part and a lower part by an intermediate baffle plate. The rotor is rotatably arranged inside the lower cavity of the shell. Magnetic steel is fixed on the top part of the rotor. The upper end surface of magnetic steel is close to the intermediate baffle plate. The torsion spring is arranged outside the rotor, wherein one end of the torsion spring is overlapped on the shell, and the other end of the torsion spring is overlapped on the rotor. The circuit board is fixed inside the upper cavity of the shell. One side surface, which is close to the intermediate baffle plate, of the circuit board is provided with a Hall element. Compared with conventional throttle valve position sensors, the throttle valve position sensor has advantages of being simple in structure, stable and reliable in operation, high in sensitivity and long in the service life.
Description
Technical field
The utility model relates to a kind of automobile sensor, is specifically related to a kind of air throttle position sensor of automobile.
Background technology
Throttle position sensor is called again engine load sensor or throttle switch, and its main function is that to detect engine be in idling operation or load condition, is accelerating mode or decelerating mode.Traditional air throttle position sensor of automobile, it is to slide on the resistor disc of PCB surface by epitrochanterian brush wires, by changing resistance value, is exported to realize the detection to throttle position.Its shortcoming is: brush wires and resistor disc to contact dynamics wayward, brush wires is easy to wear, easily causes work deviation to occur, transducer sensitivity is not high, serviceable life is shorter, simultaneously yet relative complex of structure.
Summary of the invention
In view of the deficiencies in the prior art, the utility model provide a kind of simple in structure, working stability is reliable, the throttle position sensor of highly sensitive and long service life.
For solving the problems of the technologies described above, the utility model takes following technical scheme to complete:
A kind of throttle position sensor, it is characterized in that: comprise shell, rotor, magnet steel, torsion spring and wiring board, the cavity of shell is divided into top and the bottom by central dividing plate, described rotor rotatably is located in the lower chamber of shell, described magnet steel is fixed on the top of rotor, magnet steel upper surface and central dividing plate are pressed close to, described torsion spring arranges outside rotor, torsion spring one end is overlapped on shell, the other end is overlapped on rotor, described wiring board fixedly is located in the upper cavity of shell, and the side surface that wiring board and central dividing plate are pressed close to is provided with the Hall part.
The throttle position sensor of technique scheme, it is to utilize the Hall mode to carry out detection signal, rather than traditional mechanical contact carrys out detection signal, so working stability is reliable, highly sensitive, and long service life.Its principle of work is: when throttle position changes, rotor driven synchronously rotates, and the rotation of rotor will drive the magnet steel rotation, the rotation of magnet steel can make to produce corresponding electric potential difference at the Hall element of PCB surface setting, so the wiring board output pulse signal, accurately calculate the air throttle present position.
As preferably, the lower chamber opening of described shell is provided with the locating sleeve that rotor is formed to rotating support, locating sleeve is fixed on shell by rivet, and the upper cavity opening of described shell is provided with the casing cover that the upper cavity opening is sealed, and casing cover is fixed on shell by rivet.The top end face that described rotor is relative with central dividing plate is provided with spherical surface hill, and that central dividing plate is provided with corresponding sphere is recessed.By above-mentioned design, make the utlity model has simple in structure, install that fastness is good, the reliable advantage of having stable behavior.
The accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is outside drawing of the present utility model,
Fig. 2 is cut-away view of the present utility model.
Embodiment
Accompanying drawing has meaned the technical solution of the utility model and embodiment, below further describes by reference to the accompanying drawings each details and the principle of work thereof of embodiment again.
As shown in the figure, throttle position sensor of the present utility model, comprise shell 1, rotor 11, magnet steel 9, torsion spring 10 and wiring board 6, the cavity of shell 1 is divided into upper cavity 5 and lower chamber 4 two parts by central dividing plate 8, described rotor 11 rotatably is located in the lower chamber 4 of shell, described magnet steel 9 is fixed on the top of rotor 11, magnet steel 9 upper surfaces and central dividing plate 8 are pressed close to, described torsion spring 10 arranges outside rotor, torsion spring 10 1 ends are overlapped on shell 1, the other end is overlapped on rotor 11, described wiring board 6 fixedly is located in the upper cavity 5 of shell, wiring board 6 is provided with Hall part 13 with the side surface that central dividing plate 8 is pressed close to, lower chamber 4 openings of described shell are provided with the locating sleeve 12 that rotor 11 is formed to rotating support, locating sleeve 12 is fixed on shell 1 by rivet, upper cavity 5 openings of described shell are provided with the casing cover 2 that the upper cavity opening is sealed, and casing cover 2 is fixed on shell 1 by rivet 3, the top end face that described rotor 11 is relative with central dividing plate 8 is provided with spherical surface hill 7, and that central dividing plate is provided with corresponding sphere is recessed.
The utility model is work like this: rotor 11 rotates with the variation of throttle position, rotational angle is corresponding one by one with the position of air throttle, when rotor 11 rotates, will drive magnet steel 9 rotates, the rotation of magnet steel 9 can make the Hall element 13 arranged on wiring board 6 surfaces produce corresponding electric potential difference, so wiring board 6 outputs are with respect to the voltage pulse signal of the different corners of air throttle.
