Abstract
The invention discloses an enhanced actuating cam sensor for an automobile. The enhanced actuating cam sensor comprises a shell, a plug pin arranged at the upper end of the shell, an installation hole arranged on one side of the shell, and a plug arranged at the lower end of the shell. A Hall tube and a magnet are arranged inside the shell. The shell is internally provided with a TLE 4984C chip having the TPO function. A magnetism-reduction iron core is sleeved onto the magnet. The sensor is provided with the Hall tube with the TOP chip. When the enhanced actuating cam sensor is powered up, whether a user is currently facing convex teeth or concave teeth can be detected even when a target wheel does not rotate. A magnetism-reduction sleeve is arranged on a built-in magnet, so that the magnetic flux density can be effectively dispersed. Meanwhile, the magnetic field is reduced. On the premise that the length of the magnet is long enough, the requirements of high temperature resistance can be met. At the same time, the sensitivity of the sensor is improved.
Description
Technical field
The present invention relates to a kind of automobile sensor, more particularly, to a kind of automobile enhancement mode actuating cam sensor.
Background technology
In automobile electric control system, cam sensor is the position signalling for gathering valve cam, and is input into ECU, with
Just ECU recognizes cylinder compression top dead centre, and so as to carry out sequential fuel injection control, time of ignition control and detonation are controlled.And existing skill
In the case where target wheel is not rotated, cam sensor in art cannot detect that currently face is double wedge or concave tooth, its
It is secondary as chip often has a quota to the magnetic field intensity of magnet, but as sensor is installed on the engine, building ring
Border temperature is higher, thus heatproof requires that magnetic strength intensity defines a contradiction, therefore is badly in need of a kind of skill that can be solved the above problems
Art scheme.
The content of the invention
To solve the above problems, the present invention proposes one kind and can be detected in the case where cam is not rotated, and can protect
The automobile enhancement mode actuating cam sensor of high temperature resistant demand is met in the case of holding magnet sufficient intensity.
The technical solution adopted in the present invention is：A kind of automobile enhancement mode actuating cam sensor, including housing and set
In the pin of housing upper end, and located at the installing hole of housing side, and located at the plug of housing lower end, the inside of the housing sets
Hall pipe and magnet are equipped with, the Hall pipe is built-in with the TLE4984C chips with TPO functions, a drop is set with the magnet
Magnetic core.
Further, sectional area of the sectional area of the drop magnetic core more than magnet.
Further, the magnet and drop magnetic core one piece injection are in enclosure interior.
Further, the outer surface of the housing has secondary overlay film.
Further, described installation be provided with bushing on the inside of empty.
Further, with the inserted sheet being connected with Hall pipe on the plug.
Further, the side of the housing plug end is provided with pin mark.
Compared with prior art, which has the advantages that the present invention：
The automobile enhancement mode actuating cam sensor of the present invention employs the Hall pipe with TPO chips, after its power supply,
Also can detect in the case where target wheel is not rotated that currently face is double wedge or concave tooth, on built-in magnet, be provided with drop magnetic
Set, can effectively disperse magnetic flux density, reduce magnetic field, meet high temperature resistant demand, while also improving in the case of magnet length length
The sensitivity of sensor.

State on plug 4 with the inserted sheet 10 being connected with Hall pipe 5；The side of 1 plug end of the housing is provided with pin mark 11.
The automobile enhancement mode actuating cam sensor of the present invention employs the Hall pipe with TPO chips, after its power supply,
Also can detect in the case where target wheel is not rotated that currently face is double wedge or concave tooth, on built-in magnet, be provided with drop magnetic
Set, can effectively disperse magnetic flux density, reduce magnetic field, meet high temperature resistant demand, while also improving in the case of magnet length length
The sensitivity of sensor.
Embodiment described above is only that the preferred embodiment of the present invention is described, not the structure to the present invention
Think and scope is defined.On the premise of without departing from design concept of the present invention, technology of this area ordinary person to the present invention
Various modifications and improvement that scheme is made, all should drop into protection scope of the present invention, the technology contents that the present invention is claimed,
