Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

The shift operation device of this embodiment is a device for arbitrarily performing a shift operation on an automatic transmission mounted on a vehicle by detecting the operation of the shift lever. As shown in FIGS. Rod 1 , base end portion 5 , main body 6 , first operating member 7 , second operating member 8 , link member 12 as an interlocking member, first detection mechanism 10 , and second detection mechanism 11 .

The shift lever 1 is formed by protruding upward from the main body 6, and can move in one direction a (in the present embodiment, the front-rear direction of the vehicle) and another direction (in the present embodiment, mutually orthogonal directions) which are mutually different directions (in the present embodiment, mutually orthogonal directions). The rod-shaped member operated in one direction b (in this embodiment, the width direction of the vehicle) is configured such that an operating handle N (refer to FIG. 1 ) that the driver can hold is attached to a protruding end. A base end portion 5 is integrally formed on the base end side of the shift lever 1 .

The base end portion 5 is formed of a spherical member and is supported by the support member 4 attached to the main body 6 , and is configured to rotate relative to the main body 6 in accordance with the operation of the shift lever 1 . In addition, as shown in FIG. 9, the receiving hole 5c is formed in the predetermined part of the base end part 5, and the pin-shaped member 16 and the spring 17 are accommodated in this receiving hole 5c. The pin member 16 is assembled so as to be biased by the spring 17 to press a predetermined portion of the guide member 3, and is configured to bias the shift lever 1 to an initial position in one direction a to return it.

In addition, as shown in FIG. 9( b ), at a predetermined portion (one side with respect to the main body 6 ) of the base end portion 5 is formed a vertical direction (that is, when the shift lever 1 is operated in the other direction b). As shown in FIG. 5 , the long groove 5b extending in the direction in which the base end portion 5 rotates is fitted with the convex portion 7a of the first operating member 7 in a slidable manner. In addition, at a predetermined portion of the base end portion 5 (on the other side with respect to the main body 6 ), there is an extension along the rotation axis A (see FIGS. 6 and 12 ) when the shift lever 1 is operated in one direction a (see FIGS. 6 and 12 ). As shown in FIG. 5 , the arm portion 5 a has a protruding end portion rotatably fitted into a fitting hole 12 aa of the link member 12 .

The main body 6 is fixed at a predetermined position of the vehicle, and is composed of a housing for accommodating the base end portion 5, the supporting member 4, etc., and a cover 2 covering the main body 6 and a guide for guiding the shift lever 1 are formed on the upper part thereof. Guide member 3 for slot 3a. In addition, the first operating member 7 and the second operating member 8 are attached to predetermined positions on one side of the main body 6 , and a link member (interlocking member 12 ) is attached to predetermined positions on the other side.

The first operation member 7 is operated by being transmitted with the operation force in one direction a with respect to the shift lever 1. As shown in FIG. A disc portion 7b of a metal member (not shown) having a predetermined shape (shape having a predetermined pattern) is formed on the surface. In addition, the convex portion 7a is slidably fitted into the long groove 5b of the base end portion 5, so that when the shift lever is operated in one direction a, the long groove 5b engages with the convex portion 7a to make the first operating member 7 When the shift lever 1 is operated in the other direction b, the protrusion 7a slides (moves) in the long groove 5b and the first operating member 7 does not operate. That is, the base end portion 5 and the first operating member 7 are configured to engage with the rotation of the base end portion 5 in one direction a and not engage with the rotation in the other direction b. When the lever is operated in one direction a, the first operating member 7 operates.

The link member 12 (interlocking member) can be interlocked by being transmitted with the operating force in the other direction b with respect to the shift lever 1. As shown in FIGS. 11 and 12 , the link member 12 at one end The annular portion 12a has a fitting hole 12aa into which the arm portion 5a of the base end portion 5 is fitted, and a rod-shaped transmission portion 12b connected to the second operating member 8 is formed at the other end portion. In addition, a fitting groove 12ba capable of fitting with the convex portion 8a of the second operation member 8 is formed at the protruding end of the transmission portion 12b.

The second operating member 8 operates by being transmitted the action of the link member 12 (interlocking member) (specifically, by being transmitted the operating force in the other direction b with respect to the shift lever 1 via the link member 12 ). and operate), as shown in Figure 10, the second operating member 8 is constituted as a metal member (not shown) having a protruding plate-shaped protrusion 8a and a predetermined shape (shape having a predetermined pattern) formed on the surface. Shown) the disc portion 8b. Furthermore, the convex portion 8a is fitted into the fitting groove 12ba of the link member 12, and when the shift lever is operated in the other direction b and the link member 12 rotates around the transmission portion 12b, the second operating member 8 moves. operation (specifically, it rotates in the same direction as the transmission part 12b).

However, in this embodiment, as shown in FIGS. 5 and 7 , when the link member 12 is urged by the urging mechanism 13 and mounted on the other side of the main body 6 , the transmission portion 12 b is extended to one side of the main body 6 . , the convex portion 8a is fitted into the fitting groove 12ba at the protruding end, so that the second operating member 8 is assembled so as to be able to rotate together with the transmission portion 12b. By adopting such a structure, when the shift lever 1 is operated in one direction a, the arm portion 5a idles in the fitting hole 12aa without transmitting the operating force, and when the shift lever 1 is operated in the other direction b, The link member 12 can rotate around the transmission part 12b (that is, the transmission part 12b rotates in the c direction as shown in FIG. 12 ) to move the second operation member 8 .

In addition, since the link member 12 is attached so that it may be covered with the cover 14, and the axial displacement of the transmission part 12b is restricted, only rotation centering on the transmission part 12b will be performed. In addition, the link member 12 is configured to be biased toward the initial position by the urging mechanism 13 to rotate against the urging force of the urging mechanism 13. Therefore, when the shift lever 1 is operated in the other direction b, if the driving When the operator releases the operating handle N, the link member 12 returns to the initial position (state before rotation).

The first detecting mechanism 10 can detect the operation of the shift lever 1 in one direction a by detecting the movement of the first operating member 7 (rotation of the disc portion 7b). The first detecting mechanism 10 is formed on the substrate 9 (specifically, It is said to be a sensor (in this embodiment, an inductive sensor) on a printed circuit board on which electrical wiring is printed. Specifically, the first detecting mechanism 10 is formed at a position facing the first operating member 7, and sends a signal (sine wave) of a predetermined frequency to the surface of the first operating member 7, and by detecting The signal reflected by the metal member is compared with the transmitted signal to detect the rotation angle of the first detection mechanism 10 .

Similarly, the second detection mechanism 11 can detect the operation of the shift lever 1 in the other direction b by detecting the operation of the second operation member 8 (rotation of the disc portion 8b). The sensors (inductive sensors in this embodiment) on the substrate 9 common to the detection mechanisms facing the first operating member 7 are configured. Specifically, the second detection mechanism 11 is formed at a position facing the second operating member 8, and sends a signal (sine wave) of a predetermined frequency to the surface of the second operating member 8, and by detecting The signal reflected by the metal member is compared with the transmitted signal to detect the rotation angle of the second detection mechanism 11 . In addition, the board|substrate 9 (the 1st operation member 7 and the 2nd operation member 8 are the same) is covered with the cover 15, and is assembled in one side of the main body 6. As shown in FIG.

Next, the operation of the above-mentioned shift operation device will be described.

When the shift lever 1 is swung in one direction a (the front-rear direction of the vehicle) and the base end 5 rotates in the same direction, the long groove 5b engages with the convex portion 7a and the first operating member 7 moves (specifically, In other words, rotate in the operating direction), therefore, the first detection mechanism 10 detects the rotation angle (action) of the first operating member 7, and sends the signal to the automatic transmission mounted on the vehicle to perform a shift operation. In addition, when the shift lever 1 is swung in one direction a and the base end 5 rotates in the same direction, and the arm 5a rotates (rotates around the axis) accordingly, the arm 5a idles in the fitting hole 12aa, and the operation Force is not transmitted to the link member 12, and the second operating member 8 does not operate.

On the other hand, when the shift lever 1 is swung in the other direction b (the width direction of the vehicle), and the base end portion 5 rotates in the same direction as the shift lever 1, the link member 12 rotates around the transmission portion 12b, and the second The action member 8 moves in conjunction with this (specifically, rotates in the same direction as the transmission part 12b), therefore, the rotation angle (action) of the second action member 8 is detected by the second detection mechanism 11, and the signal is sent to The transmission is sent to the automatic transmission mounted on the vehicle to perform a shift operation. In addition, when the shift lever 1 is swung in the other direction b and the base end 5 rotates in the same direction, the protrusion 7a slides (moves) in the long groove 5b without engaging, so the first movement Member 7 does not act.

According to the above-described embodiment, the link member 12 (interlocking member) is linked by being transmitted with the operating force of the shift lever 1 in the other direction b, and is linked with the operating force of the shift lever 1 in the one direction a. The transmission of the shift lever 1 is blocked (that is, the operation of the shift lever 1 with respect to one direction a and the transmission of the operating force with respect to the operation of the other direction b are independent), therefore, when the shift lever 1 is operated in one direction a In this case, the link member 12 (interlocking member) does not operate, and the non-operating state of the second operating member 8 can be maintained. Therefore, the operation of the shift lever 1 in one direction a and the operation in the other direction b can be detected with high precision. operation.

Further, in the base end portion 5 of the present embodiment, an arm portion 5a is extended along the rotation axis A when the shift lever 1 is operated in one direction a, and the link member 12 is connected to the arm portion 5a (connected to the arm portion 5a). moving member), and when the shift lever 1 is operated in one direction a, the link member 12 is idling by the connection portion (that is, the fitting hole 12aa) connected to the arm portion 5a without being transmitted with the operation force, therefore, it is possible to Transmission of the operating force of the shift lever 1 with respect to the one direction a is more reliably blocked.

Furthermore, the interlocking member of the present embodiment is composed of a link member 12 having a fitting hole 12aa into which the arm portion 5a fits is formed at one end and a transmission portion 12b connected to the second operating member 8 is formed at the other end. , when the shift lever 1 is operated in one direction a, the arm portion 5a idles in the fitting hole 12aa and the interlocking member 12 is not transmitted with the operating force, and when the shift lever 1 is operated in the other direction b Since the link member 12 rotates around the transmission portion 12b to move the second operating member 8, it is possible to more reliably block the movement of the shift lever relative to the one direction a with respect to the link member 12 (interlocking member). 1, and can more reliably transmit the operating force of the shift lever 1 in the other direction b.

Further, in the connecting portion between the first operating member 7 and the base end portion 5 of the present embodiment, a long groove 5b and a convex portion 7a fitted with the long groove 5b are respectively formed, and when the shift lever 1 is moved toward a When the direction a is operated, the long groove 5b engages with the convex portion 7a to move the first action member 7, and when the shift lever 1 is operated in the other direction b, the convex portion 7a moves in the long groove 5b and the first action member 7 moves. Since one operating member 7 does not operate, the transmission of the operating force of the shift lever 1 with respect to one direction a can be more reliably performed with respect to the first operating member 7, and the transmission of the operating force with respect to the other direction a can be more reliably blocked. b Transmission of the operating force of the shift lever 1.

In addition, according to the present embodiment, the first operation member 7 is connected to a predetermined part on one side of the main body 6, and the link member 12 (interlocking member) is connected to a predetermined part on the other side of the main body 6. Since the second operating member 8 is connected to a predetermined portion on one side, the first operating member 7 and the second operating member 8 can be arranged on one side of the main body 6, and the size of the device and the simplification of the device structure can be realized.

Furthermore, the first detecting mechanism 10 and the second detecting mechanism 11 are formed on the common substrate 9, and the first operating member 7 and the second operating member 8 are opposed to the first detecting mechanism 10 and the second detecting mechanism 11, respectively. Therefore, the miniaturization of the device and the simplification of the structure of the device can be realized, and the number of parts can be reduced. It should be noted that the first detection mechanism 10 and the second detection mechanism 11 may be formed on separate substrates, and arranged to face the first operating member 7 and the second operating member 8 .

Above, the present embodiment has been described, but the present invention is not limited thereto. For example, the first detection mechanism 10 and the second detection mechanism 11 can also be other types of sensors (for example, Hall element sensors or contact sensors, etc.) ). In addition, in this embodiment, a pivot structure (spherical support structure) in which the base end portion 5 is formed of a spherical member is adopted, but as long as the shift lever 1 is operated in one direction a and the other direction b The rotating structure can also adopt other structures.

Furthermore, in this embodiment, one direction a is the front-rear direction of the vehicle and the other direction b is the width direction of the vehicle, but the one direction a may be the width direction of the vehicle and the other direction b may be the front-rear direction of the vehicle. It should be noted that the one direction a and the other direction b may not be directions perpendicular to each other as long as they are different from each other. Furthermore, the link member 12 (interlocking member) of this embodiment has a fitting hole 12aa into which the arm part 5a fits is formed at one end and a transmission part 12b connected to the second operation member 8 is formed at the other end. As long as the transmission of the operating force of the shift lever 1 with respect to the one direction a is blocked by being linked by the operating force transmitted to the shift lever 1 in the other direction b The structure can also be in other ways (not limited to the link member).
