Abstract
The utility model discloses a crankshaft position sensor, which comprises an outer shell and a circuit board, and is characterized in that: the circuit board is installed into the interior of the outer shell from a top part opening of the outer shell, the bottom part of the circuit board is provided with a Hall tube, the Hall tube is electrically connected with the circuit board through wiring pins, the front surface of the Hall tube is close to the bottom surface of the outer shell, the back surface of the Hall tube is provided with a magnet, the magnet is fixed on the circuit board through a magnet base, and the circuit board outputs through three wiring terminals, and the top part opening of the outer shell is encapsulated by epoxy resin; and the outer shell is fixedly connected with an installation aluminum plate, and an installation hole of a sensor is formed in the installation aluminum plate. The crankshaft position sensor has the biggest advantages of simple structure, convenient assembly, low cost and good internal sealing performance.
Description
Technical field
The utility model relates to a kind of automobile sensor, what be specifically related to is a kind of automobile crane position transducer.
Background technology
Crankshaft position sensor is for detection of the automobile engine crankshaft angle position, be arranged on ignition distributor, whether can accurately detect each cylinder after engine operation works well, as certain cylinder crankshaft does not reach top dead center position, this sensor feeds back at once control module (ECU) and judges whether to travel or to stop.The crankshaft position sensor of prior art, have shell and upper cover usually, in shell, after the installation parts, will be covered with upper cover, and structure is more complicated, and assembling is also inconvenient, and the sensor internal sealing is poor; Also have, on shell, the installation of sensors hole will be set, so the outer shape complexity of shell, the structure of mould is also complicated, and upper cover also will be manufactured with mould in addition, and cost is higher.
Summary of the invention
In view of the problem that current known technology exists, the technical problems to be solved in the utility model is to provide a kind of simple in structure, easy to assembly, cost is low, inner sealing is good crankshaft position sensor.
For solving the problems of the technologies described above, the utility model takes following technical scheme to complete:
A kind of crankshaft position sensor, comprise shell and wiring board, it is characterized in that: wiring board is encased in shell from the open top of shell, the bottom of wiring board is provided with the Hall pipe, and the Hall pipe is electrically connected to wiring board by wiring pin, and the front of Hall pipe is near the shell bottom surface, the back side of Hall pipe is provided with magnet, magnet is fixed in the circuit board by magnetic receiver, and wiring board is exported by three binding posts, and the open top of described shell is by epoxy resin encapsulated.
The crankshaft position sensor of technique scheme, simple in structure, shell directly carries out embedding with epoxy resin after the inner bodies such as the wiring board of packing into, has not only omitted upper cover, and good airproof performance, and assembling simultaneously is also convenient, has also reduced manufacturing cost; The working sensor principle is: when the signal wheel rotates, form the magnetic circuit of a variation between Hall pipe in signal wheel and sensor, magnet, when the double wedge of signal wheel over against or while leaving the sensitive surface of magnet, magnetic flux changes, so the Hall pipe by the magnetic flux change information that detects after the wiring board inner modulation, output signal to control module (ECU) and judge whether to travel or to stop, guarantee traffic safety.
As optimal technical scheme, described shell is fixedly connected with aluminium sheet is installed, and the mounting hole of sensor is located at and is installed on aluminium sheet.Above-mentioned design can make the outer shape of shell be simplified, and the structure of mould also becomes simply, also is conducive to the installation of sensor simultaneously, and the intensity of mounting hole is also high.
The accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation 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, crankshaft position sensor of the present utility model, comprise plastic casing 3 and wiring board 6, wiring board 6 is encased in plastic casing 3 from the open top of plastic casing 3, the bottom of wiring board 6 is provided with Hall pipe 10, Hall pipe 10 is electrically connected to wiring board 6 by wiring pin 7, the front of Hall pipe 10 is near plastic casing 3 bottom surfaces, the back side of Hall pipe 10 is provided with magnet 9, magnet 9 is fixed on wiring board 6 by magnetic receiver 8, wiring board 6 is exported by three binding posts 2, the open top of described plastic casing 3 is by epoxy resin 1 embedding, described plastic casing 3 is fixedly connected with installation aluminium sheet 5, install aluminium sheet 5 when plastic casing 3 injection mo(u)lding with together with plastic casing 3 is cast in, the mounting hole 4 of sensor is located at and is installed on aluminium sheet 5.
The utility model is work like this: the utility model is installed on motor car engine, when the signal wheel rotates, form the magnetic circuit of a variation between Hall pipe in signal wheel and sensor, magnet, when the double wedge of signal wheel over against or while leaving the sensitive surface of magnet, magnetic flux changes, so the Hall pipe after the wiring board inner modulation, outputs signal to the magnetic flux change information that detects control module (ECU) and judges whether to travel or to stop, and guarantees traffic safety.
