Fig. 5 is for representing the key diagram in the direction in the magnetic field on the magnetic switch device 101 involved by first embodiment of the present invention.In addition, Fig. 5 is the front view of magnetic switch device 101 seen from the side of Y2 shown in Fig. 1, for convenience of explanation, eliminates housing 12 and aftermentioned reset components 18.Fig. 6 is for illustrating the front view of the rotational action Kd of the magnetic switch device 101 involved by first embodiment of the present invention, state when Fig. 6 (a) represents that operating body 11 is in the neutral position of the rotational action Kd of operating body 11, state when Fig. 6 (b) represents that operating body 11 is in final position to the left by rotational action Kd, state when Fig. 6 (c) represents that operating body 11 is in final position to the right by rotational action Kd.In addition, for convenience of explanation, the shell 12A of housing 12 is eliminated in figure 6.The chart of the magnetic density change that the rotational action Kd of the operating body 11 of the magnetic switch device 101 of Fig. 7 involved by expression the 1st execution mode of the present invention brings simulates the result of magnetic sensor 15 in the horizontal component magnetic density of equipping position.
As shown in Fig. 3 and Fig. 5, magnet 13 is geomagnetic into becomes different magnetic poles in inner circumferential side and outer circumferential side, and the magnetic field of magnet 13 is towards the projected direction Dt of MD along operating portion 11t.Simultaneously, as shown in Fig. 3 and Fig. 5, in the neutral position of the rotational action Kd of operating body 11, namely form direction from pivot center Kj towards magnetic sensor 15 towards MD along the radial direction of rotating operation body 11 in the magnetic field of magnetic sensor 15 equipping position (central portion of magnetic sensor 15).
And, the neutral position of the rotational action Kd of the operating body 11 shown in Fig. 5 and Fig. 6 (a), magnetic density is almost nil in the horizontal component of magnetic sensor 15 present position, such as, when operating body 11 to the left direction shown in Fig. 6 (b) by rotating operation time, as shown in Figure 7, the horizontal component A of magnetic density increases gradually along with the rotational angle of operating body 11 becomes large (negative direction).On the contrary, when operating body 11 to the right direction shown in Fig. 6 (c) by rotating operation time, as shown in Figure 7, as composition reciprocal with horizontal component A, the horizontal component B of magnetic density also increases gradually along with the rotational angle of operating body 11 becomes large (positive direction).As mentioned above, to a side side by during rotating operation with to the opposing party side by being formed across footpath in the opposite direction towards MD on the equipping position of magnetic sensor 15 of magnetic field during rotating operation.
As mentioned above, at magnetic switch device 101 of the present invention, when operating body 11 from the neutral position of rotational action Kd by rotating operation time, on magnetic sensor 15 equipping position, contrary direction is become towards MD by magnetic field when rotating operation by when rotating operation with to the opposing party side, so can with the rotating operation detecting magnetic field and to detect towards the magnetic sensor 15 that MD changes different both direction to a side side.Thus, owing to being the non-contact detection mechanism be made up of magnet 13 and magnetic sensor 15, so compared with contact measurement mechanism in the past, wear and tear not coming in contact between brought parts, the long lifetime of the switching device detecting both direction action can be realized.
And, as shown in Fig. 3 (b), because magnet 13 has the circular shape of the rotation direction Dk along operating body 11, even if so when operating body 11 is made magnet 13 by rotation by rotating operation, the distance that also can reduce between magnet 13 and magnetic sensor 15 changes.Therefore, when with minimum range distributed magnet 13 and magnetic sensor 15, magnet 13 and the magnetic sensor 15 that can make to be in ultimate range are more close.Thereby, it is possible to improve the accuracy of detection of bidirectional-movement.
Secondly, by the switch motion of the magnetic switch device 101 involved by explanation the 1st execution mode of the present invention.Fig. 8 is for illustrating the key diagram of magnetic sensor 15 switch motion used on the magnetic switch device 101 involved by the 1st execution mode of the present invention, Fig. 8 (a) represents side Magnetic sensing component and the output voltage change that magnetic field is timing when carrying out switch motion, Fig. 8 (b) represent opposite side Magnetic sensing component and magnetic field is negative time output voltage change when carrying out switch motion.Further, Figure 11 is for illustrating the front view of the magnetic switch device 201 involved by aftermentioned second embodiment of the present invention.Figure 15, for the figure of magnetic switch device 201 variation 4 involved by aftermentioned second embodiment of the present invention is described, is the chart of the result of the magnetic density change that the rotational action Kd simulating the operating body 11 when using magnet 23 shown in Figure 11 brings.
As shown in Figure 7, in the shape of such as magnet 13 shown in Fig. 3 and Fig. 5, the absolute value of magnetic density horizontal component the rotational action Kd of operating body 11 belong to left and right approximately near 60deg time become maximum, and according to the shape of used magnet 13 and allocation position etc., its result is also different.Such as, as shown in figure 11, when magnet 23 does not have concavity portion and forms circular shape, as shown in figure 15, absolute value about 50deg about the rotational action Kd of operating body 11 belongs to of magnetic density horizontal component becomes maximum near being, the change of its magnetic density horizontal component causes change relative to the rotational angle of operating body 11 with linearity.
Then, explanation is such as employed in magnetic field shown in Fig. 7 on magnetic sensor 15 situation time bipolar lose-lose removing from mould magnetic sensor (Alps Electric Co., Ltd, production code member HGDEDM033A).
Bipolar lose-lose removing from mould magnetic sensor 15 has the magnetic field of carrying out switch motion 2 Magnetic sensing component (GMR element) towards MD different (on the contrary) mutually.This GMR element has and detects magnetic field resistance characteristic jumpy towards MD and when magnetic field reaches some strength.This resistance characteristic jumpy is used to switch motion.
The side GMR element of magnetic sensor 15, as shown in Fig. 8 (a), is that timing is passed through that output voltage is changed and carried out switch motion in magnetic field; The opposite side GMR element of magnetic sensor 15, as shown in Fig. 8 (b), carries out switch motion by making output voltage change when being negative in magnetic field.That is, from the neutral position of the rotational action Kd of operating body 11, as shown in Fig. 6 (b), at left direction rotating operation during operating body 11, as shown in Fig. 8 (a), there is the change of output voltage in the positive side in magnetic field, carry out the switch motion of ON or OFF.Be in particular, at above-mentioned bipolar lose-lose removing from mould magnetic sensor, when magnetic field reaches 0.003 (mT), output voltage declines, and when magnetic field returns to 0.0022 (mT), output voltage rises, and carries out the switch motion of ON or OFF.In addition, during from the neutral position of operating body 11 to right direction rotating operation operating body 11 such as shown in Fig. 6 (c), as shown in Fig. 8 (b), change at the minus side output voltage in magnetic field, carry out the switch motion of ON or OFF.Be in particular, when magnetic field is-0.003 (mT), output voltage declines, and when magnetic field is-0.0022 (mT), output voltage rises, and carries out the switch motion of ON or OFF.In addition, the "positive" or "negative" in magnetic field uses to represent convenient, is defined as in the present embodiment, and on the equipping position of magnetic sensor 15, being just during left direction as Fig. 5 and Fig. 6 of the horizontal component of magnetic density, is negative during right direction.
According to said structure, make the magnetic field of carrying out switch motion different mutually towards MD owing to using 2 Magnetic sensing component (GMR element), so 2 different magnetic fields can be detected, can detect respectively operating body 11 to one side roll fall time changes of magnetic field and to the opposing party roll fall time changes of magnetic field.Thus, really reliably can detect the magnetic direction of both direction, and the switching device carrying out both direction switch motion can be provided.
And, carrying out the bipolar lose-lose removing from mould magnetic sensor of switch motion as shown in Figure 8, analog result as shown in Figure 7, the insensitive region NC1 that magnetic sensor 15 does not carry out switch motion is there is near the neutral position of operating body 11, the rotational angle of the operating body 11 brought at rotational action Kd is approximately ± 20deg near, carry out the switch motion of ON or OFF.Equally, when stating the magnet 23 without concavity portion as shown in figure 11 after a procedure, analog result as shown in figure 15, the insensitive region NC2 that magnetic sensor 15 does not carry out switch motion is there is near the neutral position of operating body 11, the angle of rotation of the operating body 11 caused at rotational action Kd is approximately ± 7deg near, carry out ON or OFF switch motion.
Insensitive region NC1 is wider than above-mentioned insensitive region NC2, is because form the concavity portion 13r than burnishing surface depression at the outer circumferential side central portion of magnet 13.Thus, the insensitive region NC of switch motion is not carried out owing to expanding magnetic sensor 15, therefore, when use has 1 magnetic sensor 15 of the multiple Magnetic sensing component carrying out switch motion with different magnetic field towards MD, the slewing area of the operating body 11 carrying out switch motion can be expanded.Thus, the switching device of the both direction switch motion carrying out the slewing area broadness of operating body 11 with 1 magnetic sensor 15 can be provided.
And, owing to expanding the insensitive region NC not carrying out switch motion, even if so be in the equipping position of the magnetic sensor 15 shown in Fig. 3 (b), the rotational angle of the operating body 11 carrying out switch motion also can be strengthened.Therefore, it is possible to 2 GMR elements of adjacent configuration magnetic sensor 15, can leave in 1 encapsulation.Thus, compared with there is the magnetic sensor of 1 Magnetic sensing component with use 2, can manufacture and assemble easily and the magnetic switch device 101 of cheapness.
Then, the reset components 18 of the magnetic switch device 101 formed involved by first embodiment of the present invention will be described.Fig. 9, for the figure of the magnetic switch device 101 involved by first embodiment of the present invention is described, is the stereogram of the shell 12A upper surface seen from the side of Z1 shown in Fig. 1.Figure 10 is for illustrating the figure of the magnetic switch device 101 involved by first embodiment of the present invention, it is the front view of shell 12A and the reset components 18 seen from the side of Y1 shown in Fig. 1, Figure 10 (a) represents operating body 11 to right side shown in same figure by the state of rotational action, and Figure 10 (b) represents that operating body 11 is in the state of the rotational action neutral position of operating body 11.In addition, to the rotational action on Figure 10 (a) right side, contrary with the direction that Fig. 6 sees, so identical with the rotational action Kd to Fig. 6 (b) left side.
