  An object of the present invention is to obtain a shift device capable of simplifying the configuration in consideration of the above facts.

  The shift device according to claim 1 includes: a shift body that is changed by being operated and displaced; a displacement portion that is displaced when the shift body is operated; and a first engagement portion. Having a second engagement portion between which the first displacement member is displaced by driving the first drive device and the first engagement portion; And a second displacement member that is displaced by being driven.

  The shift device according to claim 2 is the shift device according to claim 1, wherein the shift body is rotationally displaced to change the shift position, and the first displacement member and the second displacement member are It is arranged adjacent to the rotation axis direction of the shift body.

  The shift device according to claim 3 is the shift device according to claim 1 or 2, wherein the shift body is rotationally displaced to change the shift position, and the shift body is rotated by the shift body. By moving in the axial direction, the restriction of displacement of the displacement portion by the first engagement portion and the second engagement portion is released.

  According to the shift device of the first aspect, when the shift body is operated and displaced, the shift position of the shift body is changed. Further, when the operation means is operated, that is, when the first drive means and the second drive means are driven, the first displacement member and the second displacement member are displaced. Thereby, it can be set as the structure from which the space | interval between the 1st engaging part of a 1st displacement member and the 2nd engaging part of a 2nd displacement member is changed. As a result, the range in which the displacement portion is displaced can be limited by the first engagement portion of the first displacement member and the second engagement portion of the second displacement member, and the operation range of the shift body can be limited. The driving force of at least one of the first driving means and the second driving means is input to the displacement portion via at least one of the first engagement portion of the first displacement member and the second engagement portion of the second displacement member. By doing so, the displacement part can be configured to be displaced. Thereby, a shift body can be displaced. As described above, in the first aspect of the present invention, the displacement of the shift body is regulated by the five constituent elements of the displacement portion, the first displacement member, the second displacement member, the first drive means, and the second drive means. It can be configured, and the shift body can be displaced. Thereby, the structure of a shift apparatus can be simplified.

  According to the shift device of the second aspect, the first displacement member and the second displacement member are arranged adjacent to each other in the rotation axis direction of the shift body, so that the size of the shift body in the rotation radial direction of the shift body is large. Can be suppressed.

  According to the shift device of the third aspect, when the shift body is moved in the rotation axis direction of the shift body, the first engagement portion of the first displacement member and the second engagement portion of the second displacement member are used. The restriction on the displacement of the displacement portion is released. Thereby, the restriction | limiting of the displacement of a shift body can be cancelled | released. That is, in the invention described in claim 3, the displacement restriction of the shift body can be released without providing a switch or the like for releasing the restriction of the displacement of the shift body at a position different from the shift device.

When the shift position of the knob 12 is changed, the automatic transmission is controlled by the CPU 20 so that the automatic transmission corresponds to the shift position of the knob 12 ("P" range (parking range), "R" range (reverse range)). , “N” range (neutral range), “D” range (drive range)). The shift position of the knob 12 (shift range of the automatic transmission) is displayed on the display unit of the vehicle via the indicator circuit 22 connected to the CPU 20.

  In the present embodiment, a release operation detecting means (not shown) for detecting the movement of the knob 12 in the vertical direction is provided. Further, the release operation detection means is electrically connected to the CPU 20.

  The CPU 20 is electrically connected to an engine start / stop switch (not shown). When the engine is stopped and the engine start / stop switch is operated by the occupant, the engine is started. On the other hand, when the engine is started and the engine start / stop switch is operated by the occupant, the engine is stopped.

  Further, the CPU 20 is electrically connected to a detecting means for detecting whether or not a brake as a braking means of the vehicle is operated by the occupant, and when the brake is operated by the occupant, the vehicle Is braked. The CPU 20 is electrically connected to a lock switch (not shown) as a restricting operation unit, and the lock switch can be operated by a passenger.

  Next, an operation mechanism 24 as an operation means for restricting the rotation of the knob 12 and releasing the restriction and changing the shift position of the knob 12 to a predetermined shift position will be described.

  As shown in FIG. 1, the actuating mechanism 24 includes an autocorrect mechanism 26 as a rotating means for rotating the shift position of the knob 12 to a predetermined shift position, and controls the rotation of the knob 12 and releases the restriction. 12 includes a restricting means for restricting the 12 rotation ranges to a predetermined range and releasing the restriction, a restriction releasing means, a restricting means, and a shift lock mechanism 28 as the restriction releasing means.

The first cam 34 and the second cam 36 as the first displacement member and the second displacement member that are rotationally displaced by this are configured.

  The first motor 30 and the second motor 32 have rotating shafts 30A and 32A that are rotated to one side and the other side when energized through motor drivers 38 and 40 (see FIG. 2) connected to the CPU 20. DC motor. The first motor 30 and the second motor 32 are arranged in a state where the axial directions of the rotary shafts 30 </ b> A and 32 </ b> A are oriented in the same direction as the rotary shaft direction of the knob 12. Note that the housings 30 </ b> B and 32 </ b> B of the first motor 30 and the second motor 32 are disposed below the second cam 36. A first gear 42 and a second gear 44 are attached to the rotation shafts 30A and 32A of the first motor 30 and the second motor 32, respectively.

  As shown in FIG. 3, the first cam 34 is formed in an annular shape and is arranged coaxially with the rotation shaft of the knob 12, and from the outer peripheral side of the annular portion 34 </ b> A toward the upper side. And a projecting first engaging portion 34B.

The linear Hall ICs 46 and 48 are electrically connected to a CPU 20 that constitutes a part of a vehicle control device (not shown).

(Operation and effect of this embodiment)
Next, the operation and effect of this embodiment will be described.

  In the shift device 10 described above, as shown in FIGS. 1 to 3, when the knob 12 is disposed at the “P” position (the linear Hall IC 16 indicates that the shift position of the knob 12 is the “P” position, When the brake is not operated, the first motor 30 is driven by the shift lock mechanism 28 of the operating mechanism 24 under the control of the CPU 20. As a result, the first cam 34 is rotated in the direction of the arrow B, and as shown in FIG. 4, the first engaging portion 34B of the first cam 34 is on one side of the protrusion 12A of the knob 12 (in the direction of the arrow A). And the projection portion 12 </ b> A. When the knob 12 is in the “P” position, the second engaging portion 36B of the second cam 36 is located on the other side (arrow B direction side) of the protruding portion 12A of the knob 12. And placed in close proximity. As a result, the rotation of the knob 12 is locked (restricted), and the rotation of the knob 12 from the “P” position to the “R” position, the “N” position, and the “D” position is locked (restricted).

  On the other hand, when the knob 12 is arranged at the “P” position, when the brake is operated, the first motor 30 is driven by the control of the CPU 20 in the shift lock mechanism 28 of the operating mechanism 24, and the first motor 30 is driven. The first cam 34 is rotated in the direction of arrow A, and the first engaging portion 34B of the first cam 34 is separated from the protruding portion 12A of the knob 12. The first engagement portion 34B of the first cam 34 is disposed at a position that allows displacement of the knob 12 (projection portion 12A) to the “D” position. Thereby, the lock of the rotation of the knob 12 is released, and the knob 12 can be rotated from the “P” position to the “R” position, the “N” position, and the “D” position.

  1 to 3, when the knob 12 is disposed at the “N” position (when the linear Hall ICs 16 and 18 detect that the shift position of the knob 12 is at the “N” position). In addition, when the lock switch is operated, the first motor 30 and the second motor 32 are driven by the control of the CPU 20 in the shift lock mechanism 28 of the operating mechanism 24. As a result, the first cam 34 is rotated in the direction of the arrow B and the second cam 36 is rotated in the direction of the arrow A, and as shown in FIG. 5, the first engaging portion 34B and the first cam 34 of the first cam 34 are rotated. The second engaging portion 36B of the two cams 36 is disposed adjacent to the protruding portion 12A on one side (arrow A direction side) and the other side (arrow B direction side) of the protruding portion 12A of the knob 12. As a result, the rotation of the knob 12 is locked, and the rotation of the knob 12 from the “N” position to the “P” position, the “R” position, and the “D” position is locked.

  On the other hand, when the knob 12 is disposed at the “N” position, when the lock switch is operated while the rotation of the knob 12 from the “N” position is locked, the shift lock mechanism of the operating mechanism 24 is operated. In 28, the first motor 30 and the second motor 32 are driven under the control of the CPU 20. Accordingly, the first cam 34 is rotated in the direction of arrow A and the second cam 36 is rotated in the direction of arrow B, so that the first engagement portion 34B of the first cam 34 and the second engagement of the second cam 36 are performed. The portion 36B is separated from the protrusion 12A of the knob 12. As a result, the rotation lock of the knob 12 is released, and the knob 12 can be rotated from the “N” position to the “P” position, the “R” position, and the “D” position.

  1 to 3, when the knob 12 is arranged at a shift position ("R" position, "N" position or "D" position) other than the "P" position (shift of the knob 12). In the case where the linear Hall ICs 16 and 18 detect that the position is other than the “P” position), the second motor 32 is driven by the control of the CPU 20. As a result, the second cam 36 is rotated in the direction of arrow A, and as shown in FIG. 6, the second engagement portion 36B of the second cam 36 is moved to the “P” position side of the knob 12 (projection portion 12A). It is arranged at a position that restricts the displacement to. As a result, the operation range of the knob 12 is limited to the range from the “R” position to the “D” position.

  On the other hand, when the knob 12 is arranged at a shift position (“R” position, “N” position or “D” position) other than the “P” position, and the knob 12 has been moved in the vertical direction. Is detected by the release operation detecting means, the second motor 32 is driven under the control of the CPU 20. As a result, the second cam 36 is rotated in the direction of the arrow B, and the second engagement portion 36B of the second cam 36 is separated from the projection 12A of the knob 12. As a result, the restriction on the displacement of the knob 12 (projection 12A) toward the “P” position is released. As a result, the knob 12 is made rotatable to the “P” position.

  1 to 3, when the knob 12 is arranged at a shift position ("R" position, "N" position or "D" position) other than the "P" position (shift of the knob 12). When the engine start / stop switch is operated and the engine is stopped when the linear Hall ICs 16 and 18 detect that the position is other than the “P” position), the shift of the automatic transmission is controlled under the control of the CPU 20. The range is changed to the “P” range. Further, when the shift range of the automatic transmission is changed to the “P” range, the knob 12 is rotated to a shift position other than the “P” position after the engine is started by operating the engine start / stop switch. (Until the linear Hall ICs 16 and 18 detect that the shift position of the knob 12 has been changed to a position other than the “P” position). For this reason, whenever the engine start / stop switch is operated, the shift range of the automatic transmission is set to the “P” range.

  When the knob 12 is arranged at a shift position other than the “P” position, when the engine start / stop switch is operated (a predetermined opportunity when the engine is stopped and / or started), In the autocorrect mechanism 26 of the operating mechanism 24, the first motor 30 is driven under the control of the CPU 20. Accordingly, the first cam 34 is rotated in the direction of the arrow B, and the first engaging portion 34B of the first cam 34 presses the protruding portion 12A of the knob 12. As a result, when the rotational force of the first cam 34 is transmitted to the knob 12 and the knob 12 is rotated in the direction of arrow B and the engine start / stop switch is operated, the knob 12 is disposed at the “P” position ( The shift position of the knob 12 can be matched with the shift range of the automatic transmission.

  Here, in the shift device 10 according to the present embodiment, the knob 12 is provided with five components, that is, the protrusion 12A provided on the knob 12, the first cam 34, the second cam 36, the first motor 30, and the second motor 32. And the knob 12 can be rotated. With this configuration, the configuration of the autocorrect mechanism 26 and the shift lock mechanism 28 can be simplified, and the configuration of the shift device 10 can be simplified.

  In the present embodiment, the shift device 10 is configured such that the first cam 34 and the second cam 36 constituting a part of the autocorrect mechanism 26 and the shift lock mechanism 28 are arranged adjacent to each other in the rotation axis direction of the knob 12. An increase in the size of the body in the vertical direction can be suppressed. In addition to this, in this embodiment, the housing 30B, 32B of the first motor 30 and the second motor 32 is disposed below the second cam 36, thereby increasing the size of the shift device 10 in the vertical direction. Can be further suppressed.

  Further, in the present embodiment, by moving the knob 12 in the vertical direction, the restriction on the displacement of the knob 12 (protrusion 12A) to the “P” position side is released. Accordingly, the displacement restriction of the knob 12 can be released without providing a switch or the like for releasing the restriction of the displacement of the knob 12 toward the “P” position at a position different from the shift device 10.

  In the above-described embodiment, when the engine is stopped by operating the engine start / stop switch with the knob 12 disposed at a shift position other than the “P” position, the shift range of the automatic transmission is increased. The shift position of the knob 12 may be changed to the “P” position after being changed to the “P” range, and the shift range of the automatic transmission is changed after the shift position of the knob 12 is changed to the “P” position. It may be changed to the “P” range.

  In the above embodiment, the shift lock mechanism 28 locks and unlocks the rotation of the knob 12 from the “P” position and the “N” position, and changes the rotation range of the knob 12 from the “R” position to “D”. Restrict between positions. However, the shift lock mechanism 28 may lock and unlock the rotation of the knob 12 from a shift position other than the “P” position and the “N” position (for example, “R” position and “D” position). Further, the shift lock mechanism 28 may limit the rotation range of the knob 12 between the “N” position and the “D” position.

  Further, in the above embodiment, the autocorrect mechanism 26 changes the shift position of the knob 12 to the “P” position. However, the autocorrect mechanism 26 may change the shift position of the knob 12 to a shift position other than the “P” position (for example, “R” position, “N” position, and “D” position).

  Moreover, in the said embodiment, the shift apparatus 10 was installed in the instrument panel. However, you may install the shift apparatus 10 in a center console, a column cover, etc.

  Further, in the above-described embodiment, the example in which the present invention is applied to the shift device 10 having the knob 12 that is displaced to any one of the shift positions by being rotated has been described. Is not limited to this. For example, the present invention may be applied to a shift device having a shift body that is displaced to any one of a plurality of shift positions by moving in the front-rear and left-right directions.
