Description
Technical field
The present invention relates to sensor technology, and in particular to a kind of automobile crane position sensor.
Background technology
In automobile electric control system, crankshaft position sensor is used to detect CAP；Determine piston top dead center position
Put；And coordinate CMPS Camshaft Position Sensor to determine the basic ignition moment.The crankshaft position sensor of prior art, is generally included
The structures such as shell, skeleton, epoxy resin and injection body, wherein shell include housing and installation orifice, and skeleton includes skeleton sheet
Body, terminal, magnet steel, circuit board, Hall chip etc..Among these, because shell includes installation orifice, so mould structure is complicated；
Skeleton includes terminal, operation inconvenience during injection, low production efficiency, while terminal also wants mold, adds manufacturing cost；Magnet steel
It is pressed into skeleton, increases press-loading device, while the magnet steel being pressed into, due to there is fit clearance, long-term use of easily vibrations move
Position, causes sensor signal distortion；The epoxy cure time poured into is oversize, greatly influences production efficiency.Generally speaking
This design structure is complicated, and technical process is more, and production cycle length, more using mould, production cost is higher.
The content of the invention
Goal of the invention：It is an object of the invention to solve the deficiencies in the prior art, there is provided a kind of simple in construction, easy
In the automobile crane position sensor realized, production efficiency is high and production cost is extremely low.
Technical scheme：A kind of automobile crane position sensor of the present invention, including sensor body and it is connected to sensor
The wire harness assembly of body, the sensor body include frame body and injection body, circuit board are fixed with inside frame body,
Hall chip is welded with circuit board, magnet steel is also molded with inside frame body；The injection body cladding and frame body periphery；
The wire harness assembly includes high temperature resistant wire harness and is arranged at the protective case of wire harness periphery, and it is another that wire harness one end is connected to circuit board
End is connected with connector, and the other end of connector communicates with automobile computer controller.
Further, the Hall chip by chip stitch soldering in circuit board；
To further enhance sealing property, sealing ring is additionally provided with the injection body, is molded body and protective case
Junction is provided with flange.
It is made up in addition for the service life of enhancing protective case, the protective case of PE.
Beneficial effect：Compared with prior art, the present invention has advantages below：
(1) in the present invention, magnet steel is directly injection-moulded in frame body, is simplified production process, is saved press-loading device, raising
The reliability of product；
(2) the injection body in the present invention is molded outside frame body, and simultaneously together with the injection of mounting flange plate,
Shell injection is omitted, reduces die cost, while also cancels epoxy resin encapsulating process, is greatly enhanced production efficiency；
(3) wire harness assembly in the present invention is directly welded with circuit board wiring hole using soldering, omits terminal transition, can
Reduce by a welding sequence, it is easy to operate, while also reduce terminal die cost, simplify skeleton die structure, reduce mould into
This, improves production efficiency.
In summary, simple in construction, technical process of the invention simply easily realizes that production efficiency is high, and manufacturing cost is cheap, easily
In mass production, there are wide market prospects.

Fig. 3 is wire harness assembly structural representation in the present invention.
Embodiment
Technical solution of the present invention is described in detail below, but protection scope of the present invention is not limited to the implementation
Example.
As shown in Figure 1 to Figure 3, a kind of automobile crane position sensor of invention, sensor body and connection
In the wire harness assembly of sensor body, sensor body includes frame body 4 and injection body 6, is fixed with inside frame body 4
Circuit board 3, Hall chip 1 is welded with circuit board 3, magnet steel 2 is also molded with inside frame body 4；Injection body 6 coats and skeleton
The periphery of body 4；Wire harness assembly includes wire harness 8 and is arranged at the protective case 9 of the periphery of wire harness 8, and the one end of wire harness 8 is connected to circuit board
3 other ends are connected with connector 10, and the other end of connector 10 communicates with automobile computer controller.
Above-mentioned Hall chip 1 is by the soldering of chip stitch in circuit board 3；Sealing ring 5 and method are additionally provided with injection body 6
Orchid 7.
The present invention operation principle be：
A target wheel, the housing in target wheel side are installed in the transmission housing body of engine crankshaft end or close flywheel
On install the present invention automobile crane position sensor, wherein the sensitive surface face target wheel of automobile crane position sensor tooth
Peak or tooth paddy.
Target wheel is one 60 teeth in theory, but actually there was only the gear ring of 58 teeth (lacking 2 teeth), 2 hypodontias
Position is the reference mark that vehicle electronic control unit (ECU) identifies 1 cylinder top dead centre.When target wheel is with crank rotation, tooth peak
Pass through the sensitive surface of crankshaft position sensor with tooth paddy, the magnetic line of force of its sensitive surface is changed, and to pass through Hall core
The magnetic flux of piece 1 is changed, and the magnetic flux change information sensed is converted into square-wave signal by Hall chip 1, and is passed to
ECU, ECU are by judging the frequency of square wave, you can know the rotating speed of engine, by judging the signal of target wheel edentulous site,
The cylinder top dead center position of engine 1 is may know that, and then determines the basic ignition moment.
