Embodiment

(14) 1. Structure of Vehicle Interior 2 of Vehicle 1

(15) The structure of a vehicle interior 2 of a vehicle 1 will be described with reference to FIG. 1.

(16) As illustrated in FIG. 1, a meter unit 5 of an instrument panel 4 and a steering handle 6 are disposed in front of the location in which a driver sits. The meter unit 5 displays a speed, engine revolutions, a gear range, and the like.

(17) An acceleration pedal 9 and a brake pedal 10 are disposed in a foot part in front of the driver. A center console 7 is provided between a driver seat and a passenger seat. The center console 7 is provided so as to extend in a front-rear direction of the vehicle and an upper surface thereof is formed substantially flat so that the driver can place an arm thereon.

(18) The center console 7 is provided with a vehicle shifter device 3 and a parking switch 8. The driver causes an automatic transmission (not illustrated) of the vehicle 1 to perform a switchover among a plurality of speed ranges by operating the vehicle shifter device 3. Specifically, the vehicle shifter device 3 can perform a switchover among speed ranges including a parking range (P-range), a reverse range (R-range), a neutral range (N-range), and a drive range (D-range).

(19) The parking switch 8 is a switch, connected to a solenoid, that operates a parking brake. When the driver pulls up the front portion of the parking switch 8, the parking brake becomes effective.

(20) 2. External Structure of Vehicle Shifter Device 3 and Motion of the Upper End Part of Shift Lever 11

(21) The external structure of the vehicle shifter device 3 and the motion of the upper end part of a shift lever 11 will be described with reference to FIG. 2. FIG. 2 is a schematic plan view illustrating an excerpt a part of the center console 7 in FIG. 1.

(22) An opening 14 is provided in the upper surface of the center console 7. The opening 14 is inverted-L-shaped in plan view from a +Z side (direction orthogonal to the sheet in FIG. 2).

(23) The shift lever 11 passing through the opening 14 in a Z-direction is provided in the opening 14 of the center console 7. A shift knob 12 grasped by the driver is provided in the upper end part (end part in the front of the sheet in FIG. 2) of the shift lever 11. The shift knob 12 is provided with a push button 13 projecting toward a +X side (driver seat side). The push button 13 is depressed when the driver performs a switchover among speed ranges.

(24) The opening 14 is covered with a cover 15 except the part into which the shift lever 11 is inserted. Indicators 16 (16p, 16r, 16n, and 16d) that indicate shift positions are provided on the +X side and a −X side of the opening 14. One of these indicators 16p, 16r, 16n, and 16d that corresponds to the selected shift position emits from a −Z side (the back of the sheet in FIG. 2) so that the driver can visually recognize the shift position easily.

(25) As illustrated in FIG. 2, in the vehicle shifter device 3, a parking (P) position 3p and a reverse (R) position 3r are disposed along an X-direction. In other words, the P-position 3p and the R-position 3r are disposed on a straight line Ax1 extending in the X-direction.

(26) In contrast, in the vehicle shifter device 3, the R-position 3r, a neutral (N) position 3n, and a drive (D) position 3d are disposed along a Y-direction. That is, the R-position 3r, the N-position 3n, and the D-position 3d are disposed on a straight line Ax2 extending in the Y-direction.

(27) It should be noted here that the vehicle shifter device 3 according to the embodiment, the motion of the shift lever 11 between the P-position 3p and the R-position 3r is detected by an electric signal (by a shift-by-wire method) and the motion of the shift lever 11 among the R-position 3r, the N-position 3n, and the D-position 3d is sent to the automatic transmission as a speed change instruction via a coupled cable.

(28) Returning to FIG. 2, the straight line Ax1 intersects the straight line Ax2 substantially orthogonally. However, an angle θ.sub.1 at which the straight line Ax1 intersects the straight line Ax2 may be smaller than 90 degrees or larger than 90 degrees in consideration of the natural motion of the arm of the driver.

(29) When attempting to start the vehicle in the parking state, the driver first moves the upper end part (shift knob 12) of the shift lever 11 along the straight line Ax1 to switch the shift position from the P-position 3p to the R-position 3r. It should be noted here that, when attempting to move the shift lever 11, the driver needs to depress the push button 13.

(30) After that, when attempting to move the vehicle 1 forward, the driver switches the shift position from the R-position 3r to the D-position 3d through the N-position 3n by moving the upper end part (shift knob 12) of the shift lever 11 along the straight line Ax2 and turns off the parking switch 8 (see FIG. 1).

(31) It should be noted here that each of the corresponding indicators 16 (16p, 16r, 16n, and 16d) beside the shift lever 11 lights as the shift lever 11 moves. In addition, although not illustrated specifically, the meter unit 5 (see FIG. 1) also has indicators that indicate shift positions and each of these indicators also lights as the shift lever 11 moves.

(32) 3. Structure of Shift Lever 11

(33) The structure of the shift lever 11 will be described with reference to FIG. 3. FIG. 3 is a schematic side view illustrating the structure of the shift lever 11 in which the shift knob 12 is represented by a dashed line to clarify the internal structure.

(34) As illustrated in FIG. 3, the shift lever 11 includes a cylindrical upper lever body 17, a lower lever body 18 formed integrally with the upper lever body 17 on the −Z side of the upper lever body 17, and a rod 19 movable within the cylinders of the upper lever body 17 and the lower lever body 18 in the Z-direction. The rod 19 has a first lock lever 21 projecting toward the +X side from a middle part in the Z-direction and a second lock lever 22 projecting toward the −X side from the middle part in the Z-direction. The first lock lever 21 and the second lock lever 22 are movable up and down in the Z-direction integrally with the rod 19.

(35) In addition, the shift lever 11 includes a substantially spherical root part 20 connected to the −Z side of the lower lever body 18 and a detent case 23 projecting obliquely upward from the root part 20. The end portion of the detent case 23 accommodates a detent plunger 24 capable of moving in or out.

(36) In addition, the shift lever 11 includes a head 26 connected to an upper end part (end part on the +Z side) of the rod 19, a push head 25 having an oblique surface 25a slidable on an oblique surface 26a of the head 26, and a spring 27 that elastically biases the rod 19 toward the +Z side. It should be noted here that a coil spring is adopted as one example of the spring 27 in the shift lever 11 according to the embodiment.

(37) When the driver operates the push button 13, as the oblique surface 25a slides on the oblique surface 26a, the head 26 moves up and down and the rod 19, the first lock lever 21, and the second lock lever 22 also move up and down as indicated by arrows A.sub.1, A.sub.3, and A.sub.4. In the state in which the driver does not depress the push button 13, the rod 19, the first lock lever 21, and the second lock lever 22 are located at the upper ends of the movable ranges in the Z-direction by a biasing force of the spring 27.

(38) It should be noted here that the shift lever 11 can pivot about a center P.sub.20 of the root part 20. Although not illustrated in FIG. 3, the posture (shift position) of the shift lever 11 can be detected by a pivotal angle sensor that detects the pivotal angle of the root part 20. The detent plunger 24 can move in or out of the detent case 23 and provides tactile feeling concerning operation for the driver when the shift lever 11 enters the individual shift position.

(39) 4. Depression Depth of Push Button 13 and Locations of Lock Levers 21 and 22

(40) The relationship between the depression depth of the push button 13 and the locations of the lock levers 21 and 22 will be described with reference to FIGS. 4A-4C, which illustrate the locations of the lock levers of the shift lever. FIG. 4A is a schematic cross sectional view illustrating the state in which the driver does not depress the push button, FIG. 4B is a schematic cross sectional view illustrating the state in which the driver has shallowly depressed the push button, and FIG. 4C is a schematic cross sectional view illustrating the state in which the driver has deeply depressed the push button.

(41) (1) State in which the Driver does not Depress Push Button 13

(42) As illustrated in FIG. 4A, in the state in which the driver does not depress the push button 13, the first lock lever 21 and the second lock lever 22 are located in the upper ends of the movable ranges in the Z-direction. Accordingly, the upper ends of the first lock lever 21 and the second lock lever 22 are located at a height H.sub.1 from the center P.sub.20 (see FIG. 3).

(43) Here, the first lock lever 21 projects outside through an opening 17a opened in the upper lever body 17 and the second lock lever 22 projects outside through an opening 17b. In addition, the first lock lever 21 and the second lock lever 22 move integrally with the rod 19 that moves within a cylinder space 17c of the upper lever body 17 and a cylinder space 18a of the lower lever body 18 in the Z-direction. It should be noted here that the cylinder space 18a of the lower lever body 18 accommodates the spring 27, which elastically biases a flange section 19a of the rod 19 toward the +Z side.

(44) (2) State in which the Driver has Shallowly Depressed Push Button 13

(45) As illustrated in FIG. 4B, in the state in which the driver has shallowly depressed (performed the first operation) the push button 13, the first lock lever 21 and the second lock lever 22 are pushed down toward the −Z side integrally with the rod 19 (arrow B.sub.1). In this state, the spring 27 accommodated in the cylinder space 18a of the lower lever body 18 is compressed and reduced in length. In addition, in the state (state in FIG. 4B) in which the driver shallowly depresses the push button 13, the upper ends of the first lock lever 21 and the second lock lever 22 are located at a height H.sub.2 from the center P.sub.20 (see FIG. 3).

(46) (3) State in which the Driver has Deeply Depressed Push Button 13

(47) As illustrated in FIG. 4C, in the state in which the driver has deeply depressed (performed the second operation) the push button 13, the first lock lever 21 and the second lock lever 22 are further pushed down toward the −Z side integrally with the rod 19 (arrow B.sub.2). In this state, the spring 27 accommodated in the cylinder space 18a of the lower lever body 18 is compressed and further reduced in length.

(48) Since the spring 27 is further compressed as illustrated in FIG. 4C, the reaction force applied to the driver via the push button 13 becomes larger than in the state illustrated in FIG. 4B. In the state in FIG. 4C in which the driver has deeply depressed the push button 13, the upper ends of the first lock lever 21 and the second lock lever 22 are located at a height H.sub.3 from the center P.sub.20 (see FIG. 3).

(49) 5. Structures of First Lock Lever 21 and Second Lock Lever 22

(50) The structures of the first lock lever 21 and the second lock lever 22 will be described with reference to FIG. 5. FIG. 5 is a schematic cross sectional view taken along line V-V in FIG. 3.

(51) As illustrated in FIG. 5, in plan view of the shift lever 11 seen from the −Z side, the first lock lever 21 projects from the rod 19 toward the +X side and the second lock lever 22 projects from the rod 19 toward the −X side. The first lock lever 21 has one end connected to the rod 19 and includes a root portion 21a that extends toward the +X side and a front end portion 21b that is bent toward a +Y side at the end part on the +X side of the root portion 21a, extends toward the +Y side, and is formed integrally with the root portion 21a. On the other hand, the second lock lever 22 extends linearly toward the −X side from the point at which the second lock lever 22 is connected to the rod 19.

As illustrated in the portion surrounded by the dot-dot-dash line in FIG. 7, a plunger 30a of a solenoid 30 is inserted into the hole 28i. The plunger 30a can move in and out in the Y-direction as indicated by arrow C. It should be noted here that, as illustrated in the portion surrounded by the dot-dot-dash line in FIG. 7, the area to which the plunger 30a projects is the area on the −Y side of the lock plate 28 in which the lever bodies 17 and 18 of the shift lever 11 are movable.

(61) 7. Locking of Lock Levers 21 and 22 to Lock Plate 28 for Each Shift Position

(62) The form in which the lock levers 21 and 22 are locked to the lock plate 28 for each shift position will be described with reference to FIGS. 9A, 9B, 10A and 10B. FIG. 9A is a schematic plan view illustrating the state of the lock levers 21 and 22 with respect to the lock plate 28 when the shift position is the D-position, and FIG. 9B is a schematic plan view illustrating the state of the lock levers 21 and 22 with respect to the lock plate 28 when the shift position is the N-position. FIG. 10A is a schematic plan view illustrating the state of the lock levers 21 and 22 with respect to the lock plate 28 when the shift position is the R-position, and FIG. 10B is a schematic plan view illustrating the state of the lock levers 21 and 22 with respect to the lock plate 28 when the shift position is the P-position.

(63) As illustrated in FIG. 9A, when the shift position is the D-position 3d, the second lock lever 22 is locked to the concave part 28a of the second extension portion 28k of the lock plate 28. In this case, the first lock lever 21 is not locked to the first extension portion 28j of the lock plate 28.

(64) Next, when the shift lever 11 is moved as indicated by arrow D.sub.1, the shift position becomes the N-position 3n as illustrated in FIG. 9B. It should be noted here that the movement from the D-position 3d to the N-position 3n does not require the driver to depress the push button 13 and only requires the driver to push the shift knob 12 toward the +Y side. As illustrated in FIG. 9B, when the shift position is the N-position 3n, the second lock lever 22 is located in the end area on the +Y side of the concave part 28a of the second extension portion 28k of the lock plate 28.

(65) Next, when the shift lever 11 is moved as indicated by arrow D.sub.2, the shift position becomes the R-position 3r as illustrated in FIG. 10A. It should be noted here that the movement from the N-position 3n to the R-position 3r requires the driver to shallowly depress the push button 13 (until the state in FIG. 4B is reached) and operate the shift lever 11 so that the second lock lever 22 climbs over the convex part 28e. As illustrated in FIG. 10A, when the shift position is the R-position 3r, the second lock lever 22 is locked to the concave part 28b of the second extension portion 28k of the lock plate 28 and the front end portion 21b of the first lock lever 21 is locked to the concave part 28c of the first extension portion 28j of the lock plate 28.

(66) Next, when the shift lever 11 is moved as indicated by arrow E.sub.1, the shift position becomes the P-position 3p as illustrated in FIG. 10B. It should be noted here that the movement from the R-position 3r to the P-position 3p requires the driver to deeply depress the push button 13 (until the state in FIG. 4C is reached) and operate the shift lever 11 so that the front end portion 21b of the first lock lever 21 climbs over the convex part 28h. As illustrated in FIG. 10B, when the shift position is the P-position 3p, the front end portion 21b of the first lock lever 21 is locked to the concave part 28d of the first extension portion 28j of the lock plate 28.

(67) Although the form in which the shift position is moved in the order of the D-position 3d, the N-position 3n, the R-position 3r, and the P-position 3p has been described above as an example, an operation similar to the above can be applied to the case in which the shift position is moved in the reverse order, that is, the order of the P-position 3p, the R-position 3r, the N-position 3n, and the D-position 3d.

(68) 8. Movement from P-Position 3p to R-Position 3r

(69) The movement from the P-position 3p to the R-position 3r in the vehicle shifter device 3 will be additionally described with reference to FIG. 11. FIG. 11 is a schematic plan view illustrating the state of the plunger 30a with respect to the shift lever 11 when the shift position is the P-position.

(70) As illustrated in FIG. 11, when the shift position is the P-position 3p, the plunger 30a of the solenoid 30 projects toward the −Y side of the first extension portion 28j of the lock plate 28. Accordingly, if the driver tries to move the shift lever 11 toward the −X side by depressing only the push button 13, the plunger 30a makes contact with the lever body 17 or the lever body 18 (the lever body 18 is not illustrated in FIG. 11) and prevents the shift lever 11 from moving to the −X side. When the shift lever 11 is moved from the P-position 3p to the R-position 3r, the driver needs to perform the operation described above while depressing the brake pedal 10.

(71) [Modification]

(72) Although the operation that depresses the push button 13 shallowly is adopted as an example of the first operation as illustrated in FIG. 4B and the operation that depresses the push button 13 deeply is adopted as an example of the second operation as illustrated in FIG. 4C in the above embodiment, the disclosure is not limited to this example. For example, it is possible to adopt the operation in which the driver depresses the shift knob 12 itself toward the −Z side as the second operation.

(73) Although the first lock lever 21 is L-shaped in plan view in the above embodiment, the disclosure is not limited to this example. For example, the first lock lever may have a shape extending linearly like the second lock lever.

(74) Although two lock levers (the first lock lever 21 and the second lock lever 22) are connected to the rod 19 in the above embodiment, the disclosure is not limited to this example. For example, only one lock lever may be connected to the rod 19.

(75) Although the vehicle shifter device 3 has four positions (the D-position 3d, the N-position 3n, the R-position 3r, and the P-position 3p) in the above embodiment, the disclosure is not limited to this example. For example, the vehicle shifter device 3 may further have a position corresponding to the manual mode.

(76) Although the above embodiment adopts a right-hand drive vehicle having a driver seat on the right side in a vehicle as an example, the disclosure is applicable to a left-hand drive vehicle.
