Embodiment
With reference to the accompanying drawings each example of the present invention is described, in each figure, identical or suitable parts, symbol that part mark is identical are described.
Example 1
Fig. 1 be rotary sensing device of the present invention to be installed in the body that is fixed be side view after on the engine body, Fig. 2 is the side view cutaway drawing of the rotary sensing device of Fig. 1, Fig. 3 is the figure when a side of connector portion 8 is seen the rotary sensing device of Fig. 1.
Above-mentioned rotary sensing device comprises: device body 1 and the metallic flange plate 2 that is installed in the usefulness stamped metal mould manufacturing on this device body 1.
Device body 1 comprises: body 6, use thermoplastic resin, for example nylon 66 or PPS class synthetic resin to be embedded with first magnetoresistive element 10 and second magnetoresistive element 11 and permanent magnet 12 as magnetoelectric conversion element at its leading section; Supporting part 7, it and this body 6 are integrally formed, and from body 6 towards radially outstanding; And connector portion 8, it and supporting part 7 are integrally formed, and are embedded with the bonder terminal 9 that is connected with first magnetoresistive element 10 and second magnetoresistive element, 11 electric property.On the surface of supporting part 7, be formed with side-prominent position fixing part, instant heating weld part 15 towards connector portion 8.
Among Fig. 3, flange plate 2 shown in the dotted line is examples different with the flange plate 2 shown in the solid line with respect to the fixed position of device body 1, because the fixed position of thermal weld portion 15 in pilot hole 14 is variable, therefore can set flange plate 2 for multiple angles with respect to device body 1.
Among Fig. 3, pilot hole 14 is that central point C, angle are 180 ° semi-circular shape, but but also shown in the image pattern 4 like that, pilot hole 14A is that central point C, angle θ are 45 ° shape, but also shown in the image pattern 5 like that, pilot hole 14B is that central point C, angle θ are 90 ° shape, and these angles θ is arbitrarily.
As shown in Figure 6, the internal perisporium face of pilot hole 14C can be made and be bellows-shaped.Adopting this pilot hole 14C, is that pilot hole 14,14A, the 14B on plane compares with the internal perisporium face, and flange plate 2 is easy with respect to the positioning operation of device body 1.
It is in the body patchhole 22 that forms on the engine body 16 that above-mentioned rotary sensing device is inserted into the portion of being fixed with body 6, and the back side of flange plate 2 and the front of supporting part 7 are close to.
Afterwards, the bolt hole 17 that forms is roughly alignd with the bolt-inserting hole 13 of flange plate 2, and be connected, thereby rotary sensing device is fixed on the engine body 16 in bolt 18 inserting bolt patchholes 13 and the bolt hole 17.
At this moment, alternately being formed with the rotary body 3 that is made of magnetic of recess 4 and protuberance 5 and the configuration relation between the device body 1 on the side face is: the central axis of device body 1 passes the central point of rotary body 3, along with the rotation of rotary body 3, the recess 4 of rotary body 3 is relative successively with first magnetoresistive element 10 and second magnetoresistive element 11 with the outer peripheral face of protuberance 5.
In the rotary sensing device of said structure, the magnetic flux difference of 3 recess 4 and protuberance 5 from permanent magnet 12 to rotary body, detect the magnetic flux that the rotation along with the rotary body 3 that is connected with bent axle changes successively by first magnetoresistive element 10 and second magnetoresistive element 11, can detect the rotating speed of rotary body 3.
Adopt the rotary sensing device of this example, because device body 1 and utilize thermal weld portion 15 fixing with flange plate 2 that this device body 1 split forms, therefore, for example at the position change of the bolt hole 17 of engine body 16 time, under the situation that device body 1 is kept intact, only change flange plate 2 and just can tackle, can corresponding multiple engine body 16.
As long as just can make device body 1 and flange plate 2 integrated simply the jut thermal weld of the resin of the outer dress of constituent apparatus body 1.
In addition, because flange plate 2 is formed with the circular-arc pilot hole 14 of central point on the central axis of device body 1, and utilize the thermal weld portion 15 that is plugged in this pilot hole 14 so that above-mentioned central point is fixing as the arbitrarily angled and device body 1 at center, therefore, can make a pair of first magnetoresistive element 10,11 positive relative with the recess 4 that on the side face of rotary body 3, forms simply, can obtain the high rotary sensing device of accuracy of detection with protuberance 5.
Example 2
Fig. 7 is the side view cutaway drawing of the rotary sensing device of expression the invention process form 2, and Fig. 8 is the figure when a side of connector portion 8 is seen the rotary sensing device of Fig. 7.
In this example, be that bolt 20 is attached to flange plate 2 on the device body 1 at pilot hole 14 place use location fixed part.
Other structure is identical with example 1.
When adopting this structure, what use as position fixing part is bolt 20, compares when using thermal weld portion 15, and flange plate 2 can more be securely fixed on the device body 1.
Example 3
Fig. 9 is the side view cutaway drawing of the rotary sensing device of expression the invention process form 3.
The rotary sensing device of this example is that connector portion 8 is with respect to the rotary sensing device of body 6 towards the vertical direction bending.
Other structure is identical with example 1.
Like this, even connector portion 8, also can obtain the effect identical with example 1 with respect to the rotary sensing device of body 6 towards the vertical direction bending.
In above-mentioned each example, the detection bodies that detects the rotating speed of rotary body 3 constitutes by permanent magnet 12 with as the magnetoresistive element 10,11 of magnetoelectric conversion element, and certainly, detection bodies is not limited thereto.
For example,, both big magnetoresistive element can be used, also Hall element can be used as magnetoelectric conversion element.In addition, as detection bodies, also can use the sensor of the formula of picking up (pick up type).
In addition, the present invention for example also can be applicable to use optical sensor to detect the rotary sensing device of the position of rotary body.
In addition, what represent in above-mentioned each example is that rotary sensing device all is fixed on as the example on the engine body 16 of the body that is fixed, but as being fixed body, for example also can be the body of automatic transmission, the body of buncher.
In addition, as position fixing part, also can use rivet.
