Description

The present invention relates to a shift device.

A shift device is known that includes a shift body having an operating rod that can rotate about a pivot shaft (see, for example, Patent Document 1).

Patent document 1 discloses a technology in which a circuit board is provided so as to straddle the rotation axis of a swinging operating rod in the swing direction.

However, it is preferable to make such a shift device compact.

Chinese Utility Model No. 212587409

Taking the above facts into consideration, the present invention aims to provide a shift device that can be made compact.

A shift device according to a first aspect of the present invention includes a shift body having an operating rod rotatable about a rotation axis, and a sensor board including a sensor for detecting a rotation position of the operating rod, the sensor board being disposed on one side of the rotation axis in a rotation direction of the operating rod;
It is equipped with:

In the second aspect of the shift device of the present invention, the sensor board is disposed inward from the outer side of the shift body in the axial direction of the pivot shaft in the shift device of the first aspect of the present invention.

In the shift device of the third aspect of the present invention, in the shift device of the first or second aspect of the present invention, at least a portion of the sensor board is disposed in a recess recessed in the axial direction of the pivot shaft in the shift body.

In the fourth aspect of the shift device of the present invention, in any one of the first to third aspects of the shift device of the present invention, a rotating body is provided that is connected to the shift body by a gear, and the sensor is disposed in a position that allows detection of the rotational position of the rotating body.

In the fifth aspect of the shift device of the present invention, the sensor board in any one of the first to fourth aspects of the shift device of the present invention is arranged to avoid the rotation range of the operating rod when viewed from the axial direction of the rotation shaft.

In the shift device of the first aspect of the present invention, a sensor board is provided that includes a sensor that detects the rotational position of the operating rod. By providing the sensor board on one side of the rotation axis in the rotation direction of the operating rod, the sensor board is not positioned across the rotation axis. Therefore, the sensor board can be positioned toward the inside of the shift device in the axial direction of the rotation axis. As a result, the shift device can be made smaller in size in the axial direction of the rotation axis.

In the shift device of the second aspect of the present invention, the sensor board is disposed inside the outer side of the shift body in the axial direction of the pivot shaft, so that the sensor board is not disposed outside the outer side of the shift body in the axial direction of the pivot shaft. Therefore, the shift device can be made smaller in size in the axial direction of the pivot shaft.

In the shift device of the third aspect of the present invention, at least a portion of the sensor board is disposed in a recess in the shift body that is recessed in the axial direction of the pivot shaft, so that the sensor board is disposed close to the center of the shift body in the axial direction of the pivot shaft. This allows the shift device to be made smaller in size in the axial direction of the pivot shaft.

In the shift device of the fourth aspect of the present invention, the sensor is disposed at a position where it can detect the rotational position of the rotating body, so that the shift device equipped with a sensor board having a sensor capable of detecting the rotational position of the rotating body can be made smaller in the axial direction of the rotation shaft.

In the shift device of the fifth aspect of the present invention, the sensor board is positioned to avoid the rotation range of the operating rod when viewed from the axial direction of the pivot shaft, so that the sensor board does not need to be positioned outside the operating rod in the axial direction of the pivot shaft. Therefore, the shift device can be made smaller in size in the axial direction of the pivot shaft.

The following describes a shift device according to one embodiment with reference to the drawings. In the embodiment, an example is described in which the shift device 10 is a shift-by-wire type vehicle shift device. In each drawing, the arrow D indicates the up-down direction D of the shift body, the arrow E indicates the front-rear direction E of the shift device, and the arrow F indicates the width direction F of the shift device.

[Configuration of shift device]
1, the shift device 10 is disposed, for example, in a center console 2 provided between the driver's seat and the passenger seat in the vehicle cabin. A driver seated in the driver's seat can operate the shift device 10 to switch the shift position.

As shown in Figures 1 and 2, the shift device 10 includes a housing 20, a shift body 30, a biasing mechanism 40, a position detection mechanism 50, and a sensor board 60.

(Housing 20)
The housing 20 is formed into a rectangular box shape extending in the front-rear direction E by a first housing 21 and a second housing 22. An opening 20A that opens upward is formed in the upper rear part of the housing 20 in the front-rear direction E. A knob 36 of the shift body 30 protrudes to the outside of the housing 20 from the opening 20A of the housing 20.

As shown in FIG. 2, a part of the shift body 30, a biasing mechanism 40, a position detection mechanism 50, and a sensor board 60 are provided inside the housing 20.

(Shift body 30)
As shown in FIGS. 3 and 5 , the shift body 30 includes a main body portion 31 and a knob 36 .

<Main body portion 31>
The main body 31 comprises an axis body 32, an operating rod 33 arranged to protrude upward from the axis body 32, a first protrusion 34 arranged to protrude rearward from the axis body 32, and a second protrusion 35 arranged to protrude forward from the axis body 32.

<Shaft body 32>
The shaft body 32 is formed in a generally cylindrical shape extending in the width direction F. The shaft body 32 is configured to be rotatable about a support shaft 80 (see FIG. 2 ) attached to the housing 20. This allows the operating rod 33 to rotate about a rotation axis P extending in the width direction F. In other words, the operating rod 33 is rotatable in the front-rear direction E.

<Operation rod 33>
The operating rod 33 is formed in a columnar shape with a generally rectangular cross section that extends upward from the shaft body 32. The operating rod 33 passes through the opening 20A of the housing 20. A knob 36 is provided at the tip of the operating rod 33, and the knob 36 is exposed to the outside of the housing 20.

<First protrusion 34>
The first protrusion 34 is formed in a columnar shape with a rectangular cross section extending rearward from the shaft body 32. The first protrusion 34 is disposed on the rear side of the shaft body 32 in the rotation direction of the operating rod 33. The first protrusion 34 protrudes in a direction perpendicular to the up-down direction D of the shift body 30. A bottomed hole 34A having a bottom surface and extending in the front-rear direction E is formed on the tip surface (rear end surface) of the first protrusion 34. A moderation pin 41 and a moderation spring (compression coil spring) 42 are inserted into the bottomed hole 34A.

The moderation pin 41 has a spherical tip surface (rear end surface). The moderation pin 41 is biased by the moderation spring 42 in a direction protruding from the tip surface of the first protrusion 34.

The housing 20 is fitted with an abutment member 43 against which the tip surface of the moderation pin 41 abuts. The abutment member 43 is provided with a first abutment hole 43A, a second abutment hole 43B provided above the first abutment hole 43A, and a third abutment hole 43C provided below the first abutment hole 43A.

Between the first abutment hole 43A and the second abutment hole 43B, and between the first abutment hole 43A and the third abutment hole 43C, a moderation ridge 43D is formed so as to protrude forward.

The detent pin 41, the detent spring 42, and the abutment member 43 constitute the biasing mechanism 40 that provides a sense of detent to the operation of the operating rod 33.

<Second protruding portion 35>
3 and 5, the second protrusion 35 is formed in a columnar shape with a rectangular cross section extending forward from the shaft body 32. The second protrusion 35 is disposed on the front side of the shaft body 32 in the rotation direction of the operating rod 33. The first protrusion 34 and the second protrusion 35 protrude on opposite sides of the shaft body 32. The second protrusion 35 protrudes in a direction perpendicular to the up-down direction D of the shift body 30.

The second protrusion 35 has a recess 35B formed on the left side in the width direction F. In other words, the second protrusion 35 has a recess formed in the axial direction of the rotation axis P. A gear 35A having multiple teeth is formed on the tip surface (front end surface) of the second protrusion 35.

A holder 53 is attached to the housing 20, which rotatably holds a magnet 51 as a rotating body. The magnet 51 is formed, for example, in a cylindrical shape, and is magnetized with different magnetic poles in the circumferential direction. In other words, the magnet 51 is magnetized with a north pole on one radial side and a south pole on the other radial side. A gear 52 having multiple teeth is attached to the magnet 51. The gear 35A of the second protrusion 35 meshes with the gear 52 attached to the magnet 51, and when the operating rod 33 is operated, power is transmitted from the gear 35A to the gear 52, causing the magnet 51 to rotate. In other words, the magnet 51 is connected to the shift body 30 by the gear 35A and the gear 52.

<Sensor Board 60>
As shown in Fig. 2, the sensor board 60 is disposed to the right of the magnet 51 in the width direction F and attached to the housing 20. As shown in Fig. 5, the sensor board 60 is disposed forward in the front-rear direction E with respect to the rotation axis P. In other words, the sensor board 60 is disposed forward in the rotation direction of the operating rod 33 with respect to the rotation axis P.

As shown in Figures 3 and 4, the sensor board 60 is disposed inward in the width direction F from the outermost surface 32A of the shaft body 32, which is the outermost surface in the width direction F. In other words, the sensor board 60 is disposed inward from the outer portion of the shift body 30 in the axial direction of the rotation axis P. The rear end of the sensor board 60 is disposed so as to fit into the recess 35B recessed in the axial direction of the rotation axis P.

As shown in Figures 2 and 5, the sensor board 60 is formed in a generally rectangular plate shape extending in the front-rear direction E with the width direction F being the plate thickness direction. A first notch 60A and a second notch 60B are formed in the upper rear portion of the sensor board 60.

The first notch 60A is formed as a rectangular notch in the upper rear portion of the sensor board 60. The second notch 60B is formed in the upper rear portion of the sensor board 60, further forward than the first notch 60A. The first notch 60A and the second notch 60B are continuous and formed in a staircase shape ascending from the rear to the front.

As shown in FIG. 6, the sensor board 60 is positioned so as to avoid the rotation range R of the operating rod when viewed from the width direction F. In other words, the sensor board 60 is positioned so as to avoid the rotation range R of the operating rod 33 when viewed from the axial direction of the rotation axis P.

As shown in Figures 2 and 5, the sensor board 60 is provided with a magnetic sensor 61 as a sensor. The magnetic sensor 61 is disposed at a position where it can detect the rotational position of the magnet 51. The magnetic sensor 61 detects the direction of the magnetic field generated by the magnet 51, thereby detecting the shift position of the operating rod 33. In other words, the magnetic sensor 61 detects the rotational position of the operating rod 33.

The gear 35A, the magnet 51, the gear 52, and the magnetic sensor 61 constitute a position detection mechanism 50 that detects the shift position of the operating rod 33.

[Shift device operation]
As shown in FIG. 5, when the operating rod 33 is in the home position, the biasing force of the moderation spring 42 causes the tip surface of the moderation pin 41 to fit into the first abutment hole 43A.

As shown in FIG. 6, when the knob 36 is operated and the operating rod 33 is tilted forward from the home position, the first protrusion 34 rotates upward around the pivot axis P. At this time, the detent pin 41 moves over the detent ridge 43D and into the second abutment hole 43B. The detent pin 41 moves over the detent ridge 43D, allowing the operator of the knob 36 to feel a sense of detent.

When the knob 36 is operated and the operating rod 33 is tilted forward from the home position, the second protrusion 35 rotates downward around the pivot axis P. At this time, the downward force of the second protrusion 35 is transmitted to the gear 35A of the second protrusion 35 and the gear 52, causing the magnet 51 to rotate. The magnetic sensor 61 detects the direction of the magnetic field generated by the magnet 51, thereby detecting the shift position of the operating rod 33.

When the knob 36 is released, the first protrusion 34 moves from the second abutment hole 43B to the first abutment hole 43A with the rotation axis P as the center of rotation due to the biasing force of the moderation spring 42, and the operating rod 33 returns from its forward tilted state to its home position.

When the knob 36 is operated and the operating rod 33 is tilted backward from the home position, the first protrusion 34 rotates downward around the pivot axis P. At this time, the detent pin 41 moves over the detent ridge 43D and into the third abutment hole 43C. The detent pin 41 moves over the detent ridge 43D, allowing the operator of the knob 36 to feel a sense of detent.

When the knob 36 is operated and the operating rod 33 is tilted backward from the home position, the second protrusion 35 rotates upward around the rotation axis P. At this time, the upward force of the second protrusion 35 is transmitted to the gear 35A of the second protrusion 35 and the gear 52, causing the magnet 51 to rotate. The magnetic sensor 61 detects the direction of the magnetic field generated by the magnet 51, thereby detecting the shift position of the operating rod 33.

When the knob 36 is released, the first protrusion 34 moves from the third abutment hole 43C to the first abutment hole 43A with the rotation axis P as the center of rotation due to the biasing force of the moderation spring 42, and the operating rod 33 returns from its tilted rearward state to its home position.

[Action]
The shift device 10 of the embodiment includes a shift body 30 having an operating rod 33 that can rotate about a rotation axis P, and a sensor board 60 equipped with a magnetic sensor 61 that detects the rotational position of the operating rod 33, the sensor board 60 being arranged on the front side of the rotation direction of the operating rod 33 with respect to the rotation axis P (see Figure 5).

However, when the sensor board 60 is arranged across the rotation axis P, the sensor board 60 is arranged toward the outside of the shift device 10 in the axial direction of the rotation axis P. This creates a problem in that the shift device 10 cannot be made smaller in size in the axial direction of the rotation axis P.

The sensor board 60 includes a magnetic sensor 61 that detects the rotational position of the operating rod 33. By providing the sensor board 60 on the front side of the rotation axis P in the rotation direction of the operating rod 33, the sensor board 60 is not positioned across the rotation axis P. Therefore, the sensor board 60 can be positioned closer to the inside of the shift device 10 in the axial direction of the rotation axis P. As a result, the shift device 10 can be made smaller in size in the axial direction of the rotation axis P.

In the embodiment of the shift device 10, the sensor board 60 is positioned inside the outermost surface 32A of the shift body 30 in the axial direction of the rotation axis P (see Figure 3).

The sensor board 60 is disposed inside the outermost surface 32A of the shift body 30 in the axial direction of the rotation axis P, so that the sensor board 60 is not disposed outside the outermost surface 32A of the shift body 30 in the axial direction of the rotation axis P. Therefore, the shift device 10 can be made smaller in size in the axial direction of the rotation axis P.

In the shift device 10 of this embodiment, the rear end of the sensor board 60 in the front-rear direction E is disposed in a recess 35B recessed in the axial direction of the pivot axis P in the shift body 30 (see FIG. 3).

The rear end E of the sensor board 60 is disposed in a recess 35B recessed in the axial direction of the pivot axis P of the shift body 30, so that the sensor board 60 is disposed close to the center of the shift body 30 in the axial direction of the pivot axis P. This allows the shift device 10 to be made smaller in size in the axial direction of the pivot axis P.

In the embodiment of the shift device 10, the shift body 30 is provided with a magnet 51 connected by a gear 52, and the magnetic sensor 61 is disposed in a position where it can detect the rotational position of the magnet 51 (see FIG. 5).

The magnetic sensor 61 is disposed at a position where it can detect the rotational position of the magnet 51, so that the shift device 10 equipped with the sensor board 60 having the magnetic sensor 61 capable of detecting the rotational position of the magnet 51 can be made smaller in the axial direction of the rotation axis P.

In the shift device 10 of this embodiment, the sensor board 60 is positioned to avoid the rotation range R of the operating rod 33 when viewed from the axial direction of the rotation axis P (see Figure 6).

However, when the sensor board 60 is disposed within the rotation range R of the operating rod 33 as viewed from the axial direction of the rotation axis P, the sensor board 60 needs to be disposed in a manner that avoids the rotation range R of the operating rod 33 in the axial direction of the rotation axis P. Therefore, the sensor board 60 is disposed outside the operating rod 33 in the axial direction of the rotation axis P. As a result, there is a problem in that the shift device 10 cannot be made smaller in size in the axial direction of the rotation axis P.

The sensor board 60 is positioned to avoid the rotation range R of the operating rod 33 when viewed from the axial direction of the rotation axis P, so that the sensor board 60 does not need to be positioned outside the operating rod 33 in the axial direction of the rotation axis P. Therefore, the shift device 10 can be made smaller in size in the axial direction of the rotation axis P.

The shift device of the present invention has been described above based on the above embodiment. However, the specific configuration is not limited to this embodiment, and design changes are permitted as long as they do not deviate from the gist of the invention as defined by each claim in the claims.

In the above embodiment, an example was shown in which the upper rear part of the sensor board 60 is configured to avoid the rotation range R of the operating rod 33 by forming a first notch portion 60A and a second notch portion 60B. However, the upper rear part of the sensor board may be tapered inclined relative to the front-rear direction E to avoid the rotation range R of the operating rod 33.

In the above embodiment, an example was shown in which the sensor board 60 is disposed forward in the front-rear direction E with respect to the rotation axis P. However, the sensor board 60 may also be disposed rearward in the front-rear direction E with respect to the rotation axis P.

In the above embodiment, an example is shown in which two protrusions, the first protrusion 34 and the second protrusion 35, protrude from the shaft body 32. However, the number of protrusions protruding from the shaft body may be one, or three or more.

In the above embodiment, the shift device 10 is of a momentary type that automatically returns to the home position when the knob 36 is released. However, the shift device can also be of a stationary type that maintains the shift position by operating the knob.

In the above embodiment, an example was shown in which the holder 53 that rotatably holds the magnet 51 is attached to the housing 20. However, the magnet may be provided on the second protrusion.

In the above embodiment, the shift device 10 is disposed in the center console 2. However, the shift device may be disposed in the instrument panel, column cover, door trim, or other interior components of the vehicle.
