Abstract
The invention relates to the field of automobile sensors and discloses a camshaft position sensor. The camshaft position sensor comprises a Hall chip (1), an annular magnet (2), a housing (3), a circuit board (4) and a lead (5). The housing (3) is provided with a support, and the Hall chip (1), the annular magnet (2), the circuit board (4) and the lead (5) are fixed to the support. The lead (5) and the Hall chip (1) are welded to the upper end and the lower end of the circuit board (4) respectively. The annular magnet (2) is disposed over the Hall chip (1), and the hollow portion of the annular magnet (2) just faces the Hall chip (1). The camshaft position sensor is simple in structure, reasonable in design and high in measuring precision, and exhibits the reliable detection performance.
Description
Technical field
The present invention relates to automobile sensor field, particularly relate to a kind of CMPS Camshaft Position Sensor.
Background technology
CMPS Camshaft Position Sensor is a kind of sensor for detecting vehicle cam shaft position, and hall sensor technology is the most ripe instantly, makes sensor chip collection and output signal to ECU by Hall effect, thus realizes automobile smooth ignition.But the CMPS Camshaft Position Sensor output accuracy of existing conventional design is not high, after often needing engine cam to rotate 3 ~ 10 circles in advance, the signal of sensor ability stable output, visible Measurement reliability and precision are not high.
Summary of the invention
The invention provides a kind of CMPS Camshaft Position Sensor, solve prior art cam shaft position sensor Measurement reliability and the not high technical matters of precision.
The object of the invention is to be achieved through the following technical solutions:
A kind of CMPS Camshaft Position Sensor, comprise: Hall chip 1, ring-shaped magnet 2, housing 3, circuit board 4, wire 5, wherein, described housing 3 is provided with support, support is fixed with Hall chip 1, ring-shaped magnet 2, circuit board 4 and wire 5, described wire 5 and described Hall chip 1 are welded on the upper/lower terminal of described circuit board 4 respectively, and described ring-shaped magnet 2 is located at above described Hall chip 1, and described ring-shaped magnet 2 hollow space is just to described Hall chip 1.
Technique effect of the present invention is:
Structure is simple, reasonable in design, measuring accuracy is high, detection perform is reliable.The present invention makes than the portfire of conventional engines that vehicle exhaust discharge quantity reduces, fuel oil is more abundant.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, also can obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.

Wherein, described Hall chip 1 is positioned at above gear ring.
The present invention also comprises mounting hole 6, is provided with trip bolt in described mounting hole 6.The present invention can be fixed on cam box by trip bolt.
Ring-shaped magnet 2 is placed in the top of Hall chip by the present invention, and by ring-shaped magnet 2 hollow space just to described Hall chip 1, working sensor magnetic field is made to derive zero field region, the real-time signal that the generation of zero field region makes sensor collect is more accurate effectively, the precision exported is also higher, therefore, sensor of the present invention can export the stabilization signal that ECU needs while engine start, shortens the duration of ignition widely.
Technique effect of the present invention is:
Structure is simple, reasonable in design, measuring accuracy is high, detection perform is reliable.The present invention makes than the portfire of conventional engines that vehicle exhaust discharge quantity reduces, fuel oil is more abundant.
Be understandable that, the system architecture shown in figure does not form the restriction to system, can comprise the equipment more more or less than diagram, or combine some equipment, or different deployed with devices.
Above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
