As shown in fig. 1 and 2, a resin-made substantially cylindrical box-shaped plate 12 is provided as a support body in the shift device 10, and the plate 12 is fixed in the center console. The plate 12 is provided with an upper plate 12A on the upper side and a lower plate 12B on the lower side, and the plate 12 is configured by assembling the upper plate 12A and the lower plate 12B.

A cylindrical support tube 12C is coaxially provided in the lower plate 12B, and the support tube 12C is integrally formed with the lower wall of the lower plate 12B. A stopper surface (not shown) as a force application surface is formed on the lower surface in the lower plate 12B radially outward of the support tube 12C, and the stopper surface extends in the circumferential direction of the lower plate 12B and is inclined in a direction that goes downward from both ends in the longitudinal direction toward the center in the longitudinal direction.

A resin bracket 14 having a substantially bottomed cylindrical shape is provided as a first moving portion 1 in the plate 12, and the inside of the bracket 14 is open downward. A support tube 12C of the lower plate 12B is coaxially fitted into the holder 14, and the holder 14 is supported by the support tube 12C so as to be rotatable (movable) within a predetermined range and is restricted from moving in the vertical direction. A shift magnet 16 having a substantially rectangular columnar shape as a moving portion constituting the 1 st detection portion is fixed to the outer peripheral lower end of the bracket 14, and the shift magnet 16 is bent in the circumferential direction of the bracket 14.

A cylindrical stopper hole (not shown) is formed as a biasing hole in a lower portion of the peripheral wall of the holder 14, and is arranged parallel to the axial direction of the holder 14 and is open to the lower side. A cylindrical check pin 18 as a biasing member is fitted into the check hole, and the lower surface of the check pin 18 is curved in a convex shape. A shift spring 20 (compression coil spring) as a 1 st biasing portion is provided between the upper surface (bottom surface) of the check hole and the upper surface of the check pin 18, and the shift spring 20 biases the check pin 18 downward so that the lower surface of the check pin 18 abuts against the check surface of the lower plate 12B. The lower surface of the detent pin 18 is acted upon by a moving force that moves from both ends in the longitudinal direction of the detent surface toward the center in the longitudinal direction due to the biasing force of the shift spring 20, the lower surface of the detent pin 18 is disposed at the center (bottom) in the longitudinal direction of the detent surface, and the bracket 14 is disposed at the center position in the rotation range.

A resin link 22 (see fig. 3) having a substantially bottomed cylindrical shape is provided as a 2 nd moving part on the upper side of the holder 14 in the plate 12, and the link 22 is open inward toward the lower side. The holder 14 is coaxially fitted in the link 22, and the link 22 is supported by the holder 14 so as to be movable in the vertical direction within a predetermined range. The relative rotation of the link 22 with respect to the bracket 14 is restricted, and the link 22 can rotate integrally with the bracket 14.

A cylindrical insertion column 22A is coaxially provided in the link 22, and the insertion column 22A is integrated with an upper wall (bottom wall) of the link 22. The insertion column 22A penetrates the upper wall (bottom wall) of the holder 14 and is coaxially inserted into the holder 14, and a cylindrical selection magnet 24 as a moving part constituting the 2 nd detection part is coaxially fixed to the lower end of the insertion column 22A. The upper end portion of the link 22 coaxially penetrates the upper wall of the plate 12 (the upper wall of the upper plate 12A), and the upper end portion of the link 22 is exposed to the upper side of the plate 12.

A selection spring 26 (compression coil spring) as a 2 nd urging portion is provided between the upper wall of the holder 14 and the upper wall of the link 22, and the selection spring 26 urges the link 22 upward.

A substantially cylindrical knob 28 as a shift body is coaxially fixed to an upper side of the link 22, and the knob 28 is rotatable (rotatable in a circumferential direction (shift direction)) in one direction (a direction of an arrow a in fig. 1 and the like) and the other direction (a direction of an arrow B in fig. 1 and the like) integrally with the carrier 14 and the link 22, and is movable (displaceable in an axial direction (selection direction)) in an up-down direction integrally with the link 22. The knob 28 is exposed from the center console to the vehicle interior, and the knob 28 can be operated by a passenger (particularly, a driver) of the vehicle.

The knob 28 is disposed at an "H" position (home position) as a shift position (predetermined shift position), and the knob 28 is disposed at a "B" position (brake position) as the shift position by being rotated in one direction from the "H" position, and is disposed at an "N" position (neutral position) as the shift position by being moved downward from the "H" position. The knob 28 is rotated in one direction from the "N" position to be disposed in the "D" position (forward position) as the shift position, and is rotated in the other direction from the "H" position to be disposed in the "R" position (reverse position) as the shift position.

A substantially disc-shaped sensor substrate 30 as an installation body is coaxially fixed directly below the plate 12 (lower plate 12B).

A shift sensor 32 as a changing portion constituting the 1 st detection portion is provided on the upper surface peripheral portion of the sensor substrate 30, and the shift sensor 32 is constituted by, for example, a plurality of (four in the present embodiment) hall ICs. The shift sensor 32 is disposed below the rotation range of the shift magnet 16 of the carrier 14, and the shift sensor 32 detects the magnetic field generated by the shift magnet 16, thereby detecting the rotational position of the shift magnet 16. A selection sensor 34 as a changing portion constituting the 2 nd detection portion is provided at the center of the upper surface of the sensor substrate 30, and the selection sensor 34 is constituted by, for example, a hall IC. The selection sensor 34 is disposed below the selection magnet 24 of the link 22 (the insertion post 22A), and the selection sensor 34 detects the vertical position of the selection magnet 24 by detecting the magnetic field generated by the selection magnet 24.

Next, the operation of the present embodiment will be explained.

In the shift device 10 having the above configuration, when the knob 28 is disposed at the "H" position, the link 22 is disposed at the upper position by the biasing force of the selection spring 26, and the link 22 and the carrier 14 are disposed at the rotation range center position by the biasing force of the shift spring 20 (see fig. 4A). Therefore, the selection sensor 34 detects that the selection magnet 24 of the link 22 is disposed at the upper position, and the selection sensor 34 detects that the shift magnet 16 of the carrier 14 is disposed at the center position of the rotation range, so that the knob 28 can be disposed at the "H" position (see fig. 4B and 4C).

When the knob 28 is disposed at the "B" position, the link 22 is disposed at the upper position by the biasing force of the selection spring 26, and the link 22 and the bracket 14 are disposed at one direction side position against the biasing force of the shift spring 20 (see fig. 5A). Therefore, the selection sensor 34 detects that the selection magnet 24 of the link 22 is disposed at the upper position, and the shift sensor 32 detects that the shift magnet 16 of the bracket 14 is disposed at the one-direction-side position, whereby the knob 28 can be detected to be disposed at the "B" position (see fig. 5B and 5C).

When the knob 28 is disposed at the "N" position, the link 22 is disposed at the lower position against the biasing force of the selection spring 26, and the link 22 and the bracket 14 are disposed at the rotation range center position by the biasing force of the shift spring 20 (see fig. 6A). Therefore, the selection sensor 34 detects that the selection magnet 24 of the link 22 is disposed at the lower position, and the shift sensor 32 detects that the shift magnet 16 of the bracket 14 is disposed at the center position of the rotation range, whereby the knob 28 can be disposed at the "N" position (see fig. 6B and 6C).

When the knob 28 is disposed at the "D" position, the link 22 is disposed at the lower position against the biasing force of the selection spring 26, and the link 22 and the bracket 14 are disposed at one direction side position against the biasing force of the shift spring 20 (see fig. 7A). Therefore, the selection sensor 34 detects that the selection magnet 24 of the link 22 is disposed at the lower position, and the shift sensor 32 detects that the shift magnet 16 of the bracket 14 is disposed at the one-direction-side position, whereby the knob 28 can be disposed at the "D" position (see fig. 7B and 7C).

When the knob 28 is disposed at the "R" position, the link 22 is disposed at the lower position against the biasing force of the selection spring 26, and the link 22 and the bracket 14 are disposed at the other direction side position against the biasing force of the shift spring 20 (see fig. 8A). Therefore, the selection sensor 34 detects that the selection magnet 24 of the link 22 is disposed at the lower position, and the shift sensor 32 detects that the shift magnet 16 of the bracket 14 is disposed at the other direction side position, whereby the knob 28 can be detected to be disposed at the "R" position (see fig. 8B and 8C).

Here, the knob 28 is rotated in the circumferential direction to rotate the link 22 and the bracket 14, and the knob 28 is moved in the up-down direction to move the link 22 in the up-down direction. Therefore, the shift spring 20 biases the bracket 14, and the select spring 26 biases the link 22, whereby the knob 28 can be biased in the circumferential direction via the bracket 14 and the link 22, and the knob 28 can be biased in the vertical direction via the link 22. This makes it possible to easily set the biasing force for rotating the knob 28 in the circumferential direction and the biasing force for moving the knob 28 in the vertical direction.

Further, the shift sensor 32 detects the position of the shift magnet 16 of the carrier 14 and the circumferential position of the knob 28, and the select sensor 34 detects the position of the select magnet 24 of the link 22 and the vertical position of the knob 28, thereby detecting the position (particularly, the shift position) of the knob 28 in the circumferential direction and the vertical direction. Therefore, by detecting the circumferential position of the knob 28 and the vertical position of the knob 28, respectively, the detection accuracy of the position (particularly, the shift position) of the knob 28 in the circumferential direction and the vertical direction can be improved.

In addition, even if the operating position of the link mechanism that amplifies at least one of the amount of rotation and the amount of movement of the knob 28 in the circumferential direction is detected without detecting the position of the knob 28, the accuracy of detecting the position (particularly, the shift position) of the knob 28 in the circumferential direction and the vertical direction can be improved. Therefore, the link mechanism can be eliminated, the number of parts can be reduced, and the cost of the metal mold and the cost of the parts can be reduced. Further, the arrangement space and the working space of the link mechanism can be eliminated, and the gear shift device 10 can be downsized. Further, the operating resistance of the knob 28 can be prevented from increasing due to the link mechanism, so that the operating feeling of the knob 28 can be improved, and the knob 28 can be favorably returned to the "H" position by the biasing forces of the shift spring 20 and the select spring 26.

In the present embodiment, one selection sensor 34 is provided. However, in order to ensure redundancy, a plurality of selection sensors 34 may be provided. In this case, the plurality of selection sensors 34 may be disposed on the upper surface or the lower surface of the sensor substrate 30, or the plurality of selection sensors 34 may be disposed on the upper surface and the lower surface of the sensor substrate 30 separately.

In the present embodiment, the selection magnet 24 and the selection sensor 34 are provided. However, the selection magnet 24 and the selection sensor 34 may be changed to different types of switches (tactile switches, etc.).

In the present embodiment, the shift sensor 32 is configured by four hall ICs. However, the shift sensor 32 may be configured by 5 or more or 3 or less hall ICs. Further, if the shift sensor 32 is configured by at least 2 or more hall ICs, it is possible to detect that the knob 28 is disposed at the "H" position, the "D" position, and the "R" position.

[ 2 nd embodiment ]

Fig. 9 (1) shows the main parts of a shifting device 40 according to embodiment 2 of the present invention in a top view and a side view.

The shift device 40 of the present embodiment has substantially the same configuration as that of the above-described embodiment 1, but differs in the following points.

In the shift device 40 of the present embodiment, the shift magnet 16 is not provided on the carrier 14, and the selection magnet 24 is not provided on the link 22.

As shown in fig. 9 (1), a magnet 42 having a substantially rectangular columnar shape as a moving part is fixed to the peripheral wall of the link 22, and the magnet 42 is curved along the circumferential direction of the link 22.

The sensor substrate 30 is coaxially fixed within the plate 12, and the sensor substrate 30 is coaxially disposed within the holder 14. A sensor 44 as a changing portion is provided in the center of the upper surface of the sensor substrate 30, and the sensor 44 is constituted by, for example, a 3D hall IC. The magnet 42 of the link 22 is disposed around the sensor substrate 30, and the sensor 44 detects the magnetic field generated by the magnet 42, thereby detecting the rotational position and the vertical position of the magnet 42.

When the knob 28 is disposed at the "H" position, the link 22 is disposed at the upper position by the biasing force of the selection spring 26, and the link 22 and the bracket 14 are disposed at the rotation range center position by the biasing force of the shift spring 20. Therefore, the sensor 44 detects that the magnet 42 of the link 22 is disposed at the upper position and the rotation range center position, and thus can detect that the knob 28 is disposed at the "H" position (see fig. 9 (1)).

When the knob 28 is disposed at the "B" position, the link 22 is disposed at the upper position by the biasing force of the selection spring 26, and the link 22 and the bracket 14 are disposed at one direction side position corresponding to the biasing force of the shift spring 20. Therefore, the sensor 44 detects that the magnet 42 of the link 22 is disposed at the upper position and the one-side position, and thus can detect that the knob 28 is disposed at the "B" position (see fig. 9 (2)).

When the knob 28 is disposed at the "N" position, the link 22 is disposed at the lower position against the biasing force of the selection spring 26, and the link 22 and the bracket 14 are disposed at the rotation range center position by the biasing force of the shift spring 20. Therefore, the sensor 44 detects that the magnet 42 of the link 22 is disposed at the lower position and the rotation range center position, and thus can detect that the knob 28 is disposed at the "N" position (see (3) of fig. 9).

When the knob 28 is disposed at the "D" position, the link 22 is disposed at the lower position against the urging force of the selection spring 26, and the link 22 and the bracket 14 are disposed at one direction side position against the urging force of the shift spring 20. Therefore, the sensor 44 detects that the magnet 42 of the link 22 is disposed at the lower position and at the one-side position, and thus can detect that the knob 28 is disposed at the "D" position (see (4) of fig. 9).

When the knob 28 is disposed at the "R" position, the link 22 is disposed at the lower position against the urging force of the selection spring 26, and the link 22 and the bracket 14 are disposed at the other direction side position against the urging force of the shift spring 20. Therefore, the sensor 44 detects that the magnet 42 of the link 22 is disposed at the lower position and the other direction side position, and thus can detect that the knob 28 is disposed at the "R" position (see (5) of fig. 9).

Here, the present embodiment can also provide the same operation and effect as those of embodiment 1.

In particular, when the link 22 is disposed at the upper position, the magnet 42 is disposed above the sensor 44, and when the link 22 is disposed at the lower position, the magnet 42 is disposed below the sensor 44. Therefore, when the link 22 is disposed at the upper position and when the link 22 is disposed at the lower position, the position of the magnet 42 with respect to the sensor 44 can be changed greatly, and the magnetic field of the magnet 42 detected by the sensor 44 when the link 22 is disposed at the upper position and the magnetic field of the magnet 42 detected by the sensor 44 when the link 22 is disposed at the lower position can be changed greatly. This can improve the accuracy with which the sensor 44 detects the rotational position and the vertical position of the magnet 42, and can improve the detection accuracy of the position (particularly, the shift position) of the knob 28 in the circumferential direction and the vertical direction.

In addition, only one magnet 42 is provided. Therefore, the component cost can be reduced. Further, the arrangement space and the working space of the magnet 42 can be reduced, and the gear shift device 40 can be downsized.

[ embodiment 3 ]

Fig. 10 (1) shows the main parts of a shifting device 50 according to embodiment 3 of the present invention in a top view and a side view.

The shift device 50 of the present embodiment has substantially the same configuration as that of the above-described embodiment 2, but differs in the following points.

As shown in fig. 10 (1), in the shift device 50 of the present embodiment, 2 magnets 42 are fixed to the circumferential wall of the link 22, and the 2 magnets 42 face each other in the radial direction of the link 22. The surface of one magnet 42 on the side of the central axis of the link 22 forms an N-pole, and the surface of the other magnet 42 on the side of the central axis of the link 22 forms an S-pole. The 2 magnets 42 are arranged around the sensor substrate 30, and the sensor 44 of the sensor substrate 30 detects the magnetic field generated by the 2 magnets 42, thereby detecting the rotational position and the vertical position of the 2 magnets 42.

When the knob 28 is disposed at the "H" position, the link 22 is disposed at the upper position by the biasing force of the selection spring 26, and the link 22 and the bracket 14 are disposed at the rotation range center position by the biasing force of the shift spring 20. Therefore, the sensor 44 detects that the 2 magnets 42 of the link 22 are disposed at the upper position and the rotation range center position, and thus can detect that the knob 28 is disposed at the "H" position (see fig. 10 (1)).

When the knob 28 is disposed at the "B" position, the link 22 is disposed at the upper position by the biasing force of the selection spring 26, and the link 22 and the bracket 14 are disposed at one direction side position against the biasing force of the shift spring 20. Therefore, the sensor 44 detects that the 2 magnets 42 of the link 22 are disposed at the upper position and the one-side position, and thus can detect that the knob 28 is disposed at the "B" position (see (2) of fig. 10).

When the knob 28 is disposed at the "N" position, the link 22 is disposed at the lower position against the biasing force of the selection spring 26, and the link 22 and the bracket 14 are disposed at the rotation range center position by the biasing force of the shift spring 20. Therefore, the sensor 44 detects that the 2 magnets 42 of the link 22 are disposed at the lower position and the rotation range center position, and thus can detect that the knob 28 is disposed at the "N" position (see (3) of fig. 10).

When the knob 28 is disposed at the "D" position, the link 22 is disposed at the lower position against the biasing force of the selection spring 26, and the link 22 and the bracket 14 are disposed at one direction side position against the biasing force of the shift spring 20. Therefore, the sensor 44 detects that the 2 magnets 42 of the link 22 are disposed at the lower position and the one-side position, and thus can detect that the knob 28 is disposed at the "D" position (see (4) of fig. 10).

When the knob 28 is disposed at the "R" position, the link 22 is disposed at the lower position against the urging force of the selection spring 26, and the link 22 and the bracket 14 are disposed at the other direction side position against the urging force of the shift spring 20. Therefore, the sensor 44 detects that the 2 magnets 42 of the link 22 are disposed at the lower position and the other direction side position, and thus can detect that the knob 28 is disposed at the "R" position (see (5) of fig. 10).

Here, in the present embodiment, the same operations and effects as those of the above-described embodiment 2 can be obtained in addition to the operations and effects obtained by providing one magnet 42.

In addition, 2 magnets 42 are provided. Therefore, the magnetic field generated by the 2 magnets 42 can be stabilized, and the magnetic field formed by the 2 magnets 42 detected by the sensor 44 can be stabilized. This can further improve the accuracy with which the sensor 44 detects the rotational position and the vertical position of the 2 magnets 42, and can further improve the detection accuracy of the position (particularly, the shift position) of the knob 28 in the circumferential direction and the vertical direction. Further, it is possible to design the component so as to be durable against rattling caused by manufacturing variations of the component.

In the present embodiment, 2 magnets 42 are provided. However, more than 3 magnets 42 may be provided.

In addition, in the above-described

embodiments

2 and 3, 1 sensor 44 is provided. However, in order to ensure redundancy, a plurality of sensors 44 may be provided. In addition, instead of detecting all the shift positions of the knob 28 by one sensor 44, all the shift positions of the knob 28 may be detected by a combination of hall elements and MRE elements, which are change portions, one by one.

In addition, in the above-described embodiments 1 to 3, the "B" position and the "D" position of the knob 28 are formed to be the same as the rotational positions (rotational angles) of the "H" position and the "N" position, and the "B" position and the "D" position and the "R" position of the knob 28 are formed to be the same as the rotational positions (rotational angles) of the "H" position and the "N" position. However, the "B" position and the "D" position of the knob 28 may not be formed to be the same as each other with respect to the rotational positions (rotational angles) of the "H" position and the "N" position, or at least one of the "B" position and the "D" position and the "R" position of the knob 28 may not be formed to be the same as each other with respect to the rotational positions (rotational angles) of the "H" position and the "N" position.

In the above-described embodiments 1 to 3, the shift magnet 16, the selection magnet 24, and the magnet 42 are provided on the knob 28 side, and the shift sensor 32, the selection sensor 34, and the sensor 44 are provided on the plate 12 side. However, at least one of the shift magnet 16, the selection magnet 24, and the magnet 42 may be provided on the plate 12 side, and at least one of the shift sensor 32, the selection sensor 34, and the sensor 44 may be provided on the knob 28 side.

In addition, in the above-described embodiments 1 to 3, the knob 28 can be moved downward from the "H" position. However, the knob 28 can also be moved upward from the "H" position.

In addition, in the above-described embodiments 1 to 3, the

shift devices

10, 40, and 50 are provided on the center console. However, the shifting

devices

10, 40, 50 may be provided on the dashboard or the steering column cover.
