DETAILED DESCRIPTION OF THE INVENTION
A non-contact switch according to an embodiment of the present invention and a shift lever device using the non-contact switch according to an embodiment of the present invention will be described with reference to FIGS.
First, the shift lever device 10 in which the non-contact switch 70 is used will be described.
The shift lever device 10 has an automatic transmission mode 11 and a manual transmission mode 12 as shown in FIG.
[0008]
The automatic transmission mode 11 is a mode in which four positions of a P (parking) position 11a, an R (reverse) position 11b, an N (neutral) position 11c, and a D (drive) position 11d are arranged linearly or zigzag ( In the illustrated example, a zigzag shape is shown). However, the automatic transmission mode 11 may not have all the positions of P, R, N, and D. In addition to the four positions of P, R, N, and D, 3 (third), 2 It may have a position such as (second) or L (low).
The manual shift mode 12 is a mode in which three positions of an M (manual) position 12a, a + position 12b, and a − position 12c are arranged in a straight line. Shift operation from the M position 12a to the + position 12b and the-position 12c is possible. When the shift lever 20 is put in the + position 12b and returned to the M position 12a during traveling, the gear shifts up by the first speed, and every time it enters the + position 12b, the gear is shifted up. -Position 12c is shifted down conversely. The shift lever 20 is not held at the + position 12b and the − position 12c, and is biased by a spring (not shown) so as to return to the M position 12a when the hand is released.
Of the automatic transmission mode 11, the shift position reached when the shift lever 20 is moved from the manual transmission mode 12 to the automatic transmission mode 11 is, for example, the D position 11d. However, the position is not limited to the D position 11d. Of the manual shift mode 12, the shift position reached when the shift lever 20 is moved from the automatic shift mode 11 to the manual shift mode 12 is the M position 12a.
[0009]
As shown in FIGS. 1 and 4, the shift lever device 10 includes a shift lever 20, an ECU case 30, a printed circuit board 40, a link 50, and a holder 60. However, the link 50 is not an essential configuration requirement.

The holder operating unit 21 does not engage with the holder 60 when the shift lever 20 is in the automatic transmission mode 11, and engages with the holder 60 when the shift lever 20 is in the manual transmission mode 12.
[0010]
The ECU case 30 is fixed to the base plate. The ECU case 30 is located inside the base plate.
The printed circuit board 40 is fixed to the base plate via the ECU case 30. The printed circuit board 40 is disposed inside the ECU case 30.
[0011]
As shown in FIG. 4, the link 50 is attached to the base plate or the ECU case 30. Hereinafter, in the embodiment of the present invention, a case where the link 50 is attached to the ECU case 30 will be described as an example.
The link 50 is disposed on the outer surface of the ECU case 30 that faces the shift lever 20. The link 50 is movably supported by the ECU case 30. Here, the movement of the link 50 with respect to the ECU case 30 may be linear movement or rotation (in the illustrated example, the case of rotation is shown). Hereinafter, in the embodiment of the present invention, a case where the link 50 rotates with respect to the ECU case 30 will be described as an example.
The link 50 is supported by the ECU case 30 so as to be rotatable in the vertical direction within a plane parallel to or substantially parallel to the plane on which the operation receiving side element 72 of the non-contact switch 70 is disposed. The link 50 is always urged to rotate downward by a link urging spring 51. One end of the link biasing spring 51 is applied to the link 50, and the other end of the link biasing spring 51 is applied to the ECU case 30.
The link 50 has a guide 52. The guide 52 consists of a groove provided in the link 50, for example. The guide 52 extends in the same direction as the direction in which the holder operating portion 21 moves when the shift lever 20 is moved in the manual transmission mode 12. The guide 52 may extend on a straight line, or may extend on an arc centering on the swing axis of the shift lever 20 (in the illustrated example, the case where the guide 52 extends on the arc is shown).
[0012]
The holder 60 is movably attached to the link 50. The holder 60 is movable with respect to the link 50 in a plane parallel or substantially parallel to the plane on which the operation receiving side element 72 of the non-contact switch 70 is disposed. However, the holder 60 is movably attached to the ECU case 30 or the base plate when the link 50 is not provided.
As shown in FIG. 2, the holder 60 includes a claw portion 61, an inclined surface 62, and a contact surface 63.
[0013]
The claw portion 61 enters the guide 52 of the link 50. Since the claw portion 61 enters the guide 52 of the link 50, the holder 60 can move along the guide 52 in the guide 52 in the extending direction of the guide 52. The holder 60 does not move with respect to the link 50 in a direction perpendicular to the extending direction of the guide 52.
As shown in FIG. 1, the inclined surface 62 is a surface that is inclined downward in a direction away from the shift lever 20. The inclined surface 62 is capable of sliding contact (engagement) with the holder operating portion 21. The inclined surface 62 is not in contact with the holder operating unit 21 when the shift lever 20 is positioned in the automatic transmission mode 11, and when the shift lever 20 is moved from the automatic transmission mode 11 to the manual transmission mode 12, the holder operating unit When the shift lever 20 is positioned in the manual shift mode 12, it comes into contact with the holder operating portion 21.
(I) When the shift lever 20 is in the automatic transmission mode 11, the holder 60 is moved to the holder 60 or the link 50 by the biasing force of the link biasing spring 51. (Ii) When the shift lever 20 is moved from the automatic transmission mode 11 to the manual transmission mode 12, the holder 60 is linked by the holder actuating unit 21 until it hits the stopper 31 provided in the ECU case 30. (Iii) When the shift lever 20 is located in the manual speed change mode 12, the holder 60 is moved by the holder actuating portion 21 of the link biasing spring 51. It continues to be located in the position raised upward together with the link 50 against the urging force, and (iv) the shift lever 20 is When moving from the manual shift mode 12 to the automatic shift mode 11, the holder 60 is lowered together with the link 50 by the biasing force of the link biasing spring 51.
The abutment surface 63 can abut (engage) with the holder operating portion 21. The contact surface 63 contacts the holder operating portion 21 when the shift lever 20 is moved in the manual transmission mode 12. Since the contact surface 63 contacts the holder operating portion 21, the holder 60 moves with the holder operating portion 21 along the guide 52 of the link 50 when the shift lever 20 is moved in the manual transmission mode 12.
[0014]
Next, the non-contact switch 70 will be described.
The non-contact switch 70 may be a reed switch, a switch using a Hall element, or a switch using an optical sensor. Hereinafter, in the embodiment of the present invention, the case where the non-contact switch 70 is a switch using a Hall element will be described as an example.
The non-contact switch 70 has an operation side element 71 and an operation reception side element 72.
The operating side element 71 is provided on the holder 60. The operation receiving side element 72 is provided on the base plate or the ECU case 30 or the printed board 40 (in the illustrated example, the case where the operation receiving side element 72 is provided on the printed board 40 is shown). Hereinafter, in the embodiment of the present invention, a case where the operation receiving side element 72 is provided on the printed circuit board 40 will be described as an example.
[0015]

The first to third operation receiving side elements 72a, 72b, 72c are arranged on the same surface 41 of the printed circuit board 40 on the shift lever 20 side. Surfaces 72d, 72e, 72f of the first to third operation receiving side elements 72a, 72b, 72c facing the operation side element 71 are planes parallel to the surface 41 of the printed circuit board 40.
It is desirable that the first to third operation receiving side elements 72a, 72b and 72c detect only a magnetic field in a direction orthogonal to the operation side element facing surfaces 72d, 72e and 72f.
[0016]
Here, the operation of the embodiment of the present invention will be described.
(I) When the shift lever 20 is positioned in the automatic transmission mode 11 As shown by a two-dot chain line in FIG. 1, the holder operating portion 21 is not engaged with the holder 60. The holder 60 is in a position lowered downward by the urging force of the link urging spring 51 together with the link 50. The holder 60 or the link 50 is in contact with the stopper 31. The operation side element 71 is in a position lowered downward from a position facing the first operation receiving side element 72a. The operation side element 71 does not face the operation reception side element 72.
[0017]
(Ii) When the shift lever 20 is moved from the automatic transmission mode 11 to the manual transmission mode 12 The holder operation unit 21 contacts the inclined surface 62 of the holder 60. When the shift lever 20 is further moved to the M position 12a side, the holder operating portion 21 slides on the inclined surface 62 and pushes up the holder 60 upward. The holder 60 moves upward in a plane parallel to or substantially parallel to the surface 41 against the urging force of the link urging spring 51 together with the link 50.
[0018]
(Iii) When the shift lever 20 is positioned at the M position 12a The holder operating portion 21 is in contact with the inclined surface 62 and the contact surface 63 of the holder 60. The holder 60 is in a position moved upward together with the link 50 because the holder operating portion 21 is in contact with the inclined surface 62. The operation side element 71 is located at a position facing the first operation receiving side element 72a. Since the operation side element 71 is in a position facing the first operation receiving side element 72a, it can be detected that the shift lever 20 is positioned at the M position 12a.
[0019]
(Iv) When the shift lever 20 is moved from the M position 12 a to the + position 12 b or the − position 12 c The holder operating unit 21 is in contact with the inclined surface 62 and the contact surface 63 of the holder 60. The holder 60 is in a position moved upward together with the link 50 because the holder operating portion 21 is in contact with the inclined surface 62. The holder 60 moves together with the holder operating part 21 because the holder operating part 21 is in contact with the contact surface 63. The holder 60 moves in a plane parallel or substantially parallel to the surface 41.
[0020]
(V) When the shift lever 20 is at the + position 12 b or the − position 12 c The holder operating portion 21 is in contact with the inclined surface 62 and the contact surface 63 of the holder 60. The holder 60 is in a position moved upward together with the link 50 because the holder operating portion 21 is in contact with the inclined surface 62. The operation side element 71 is in a position facing the second operation reception side element 72b or the third operation reception side element 72c. Since the operation side element 71 is in a position facing the second operation reception side element 72b or the third operation reception side element 72c, it can be detected that the shift lever 20 is positioned in the + position 12b or the − position 12c.
[0021]
Next, the operation of the embodiment of the present invention will be described.
In the embodiment of the present invention, even when the non-contact switch 70 is used in the shift lever device 10 provided with the manual transmission mode 12, the operation receiving side element 72 is arranged in the moving direction of the operation side element 71 with respect to the operation receiving side element 72. The direction is parallel to or substantially parallel to the surface 41 to be formed. Therefore, compared with the case where the moving direction of the operation side element 71 relative to the operation receiving side element 72 is set to a direction orthogonal to the surface 41, the position detection accuracy is easily obtained. Therefore, even when the magnetic force of the actuating element 71 is changed due to a temperature change or the like, the influence can be reduced.
[0022]
Further, since the non-contact switch 70 is used, the following actions a) to c) can be obtained.
a) The durability of the switch is semi-permanent.
b) No sound is generated when the switch is switched.
c) There is no need to provide a hole in the ECU case 30. Therefore, by not providing a hole in the ECU case 30, it is possible to prevent foreign matters such as water and dust from entering the ECU case 30.
[0023]
Further, as shown in FIG. 3, the position of the actuating element 71 at the D position 11d and the position of the actuating element 71 at the M position 12a, + position 12b, and −position 12c are different in the vertical direction. There is no need to line up four actuating receiver elements, including actuating receiver elements for detecting the D position, in a horizontal row. Therefore, not only is the space in the longitudinal direction small, but it is also possible to prevent the D position from being detected when in the manual transmission mode 12.
[0024]
【The invention's effect】
According to the shift lever device of the first or second aspect, the actuating side element and the actuating receiving side element are moved in a direction parallel or substantially parallel to a plane on which the actuating receiving side element is arranged. Work together. Therefore, even when a non-contact switch is used in a shift lever device having a manual shift mode, position detection accuracy is easily obtained.
