Abstract

Simplify the structure. [Solution] In the shift device, the detection board 18 is positioned perpendicular to the rotational width direction of the lever. When the lever is rotated, the rotational position of the lever is detected by the detection board 18, and the shift position is changed. In addition, when the LED 28 emits light, the light is incident, guided, and emitted in the light guide 26, illuminating the display 32. Here, the LED 28 is provided on the detection board 18, and the incident and emitted directions of light in the light guide 26 are perpendicular. Therefore, even when the LED 28 and the display 32 are not facing each other, it is not necessary to provide an LED 28 separately from the detection board 18, and the configuration can be simplified.

Modes for Carrying Out the Invention

[0020] FIG. 1 shows a perspective view of a shift device 10 according to an embodiment of the present invention as viewed from the rear diagonally rightward, and FIG. 2 shows a perspective view of the shift device 10 as viewed from the lower diagonally leftward. In the drawings, the front of the shift device 10 is indicated by an arrow FR, the left side of the shift device 10 is indicated by an arrow LH, and the upper side of the shift device 10 is indicated by an arrow UP.

[0021] The shift device 10 according to the present embodiment is installed in a console (not shown) of a vehicle (automobile), and the front, left, and upper sides of the shift device 10 are respectively directed toward the front side, the right side, and the upper side of the vehicle.

[0022] As shown in FIGS. 1 and 2, the shift device 10 is provided with a substantially rectangular parallelepiped box-shaped housing 12 as a container, and the housing 12 is fixed in the console, and the shift device 10 is installed in the console. The housing 12 is provided with a left housing 12A on the left side and a right housing 12B on the right side, and the housing 12 is configured by assembling the left housing 12A and the right housing 12B. Further, the upper surface of the front portion of the housing 12 is open.

[0023] A substantially rectangular columnar lever 14 as a shift body is supported in the rear portion of the housing 12, and the lever 14 is rotatable (movable) in the front-rear direction about the lower end portion (base end portion). The lever 14 is rotatably penetrated through the upper wall of the housing 12 and protrudes above the console (inside the vehicle compartment), and the lever 14 can be rotated by an occupant at the upper end portion (tip portion).

[0024] The front side (gear teeth) of the lower end portion of the lever 14 is engaged with a sensor gear 16, and the sensor gear 16 is supported rotatably in the housing 12 around the left-right direction. A substantially disk-shaped magnet 16A is coaxially fixed to the right side of the sensor gear 16, and when the lever 14 is rotated, the sensor gear 16 and the magnet 16A are integrally rotated. [[ID=!7]]

[0025] Inside the housing 12, a roughly rectangular plate-shaped detection board 18 (circuit board) is fixed to the right of the lever 14 and magnet 16A, and the detection board 18 is positioned perpendicular to the left-right direction (the direction of the rotation width and rotation axis of the lever 14). On the left side of the detection board 18, a shift sensor (not shown) is provided to the right of the magnet 16A, and the shift sensor detects the rotational position of the magnet 16A based on the magnetic field generated by the magnet 16A, thereby detecting the rotational position of the sensor gear 16 and the rotational position of the lever 14.

[0026] The detection board 18 is electrically connected to the vehicle's control device 20, and the vehicle's transmission 22 is electrically connected to the control device 20. When the lever 14 is rotated and the rotation position of the lever 14 is detected by the shift sensor on the detection board 18, the control device 20 controls the shift position of the transmission 22 to the R position (reverse position), N position (neutral position), D position (drive position), or M position (manual position).

[0027] A lampshade 24 (see Figures 4(A) and 5(B)) made of opaque resin and shaped like a roughly rectangular parallelepiped box is fixed to the upper part of the front portion of the housing 12, and the lower surface of the lampshade 24 is open. Multiple (eight in this embodiment) roughly rectangular cylindrical shielding tubes 24A are integrally provided on the upper wall of the lampshade 24, and the axial direction of the shielding tubes 24A is bent in a roughly L-shape. The lower portion (base end portion) of the shielding tube 24A extends in the left-right direction, with its interior open to the right, and the upper portion (tip portion) of the shielding tube 24A extends in the up-down direction, penetrates the upper wall of the lampshade 24, and its interior is open upward. In addition, the outer side wall (left side and lower side) of the corner between the lower and upper portions of the shielding tube 24A is inclined upward as it moves to the left.

[0028] Inside each shielding cylinder 24A, a light guide 26 (see Figure 4(B)) made of transparent resin and shaped like a roughly rectangular column is inserted as a guide. The light guide 26 is formed by two-color molding (integral molding) with the lampshade 24, and its side is in close contact with and fixed to the inner circumferential surface of the shielding cylinder 24A. The axial direction of the light guide 26 is bent in a roughly L-shape along the axial direction of the shielding cylinder 24A. The lower part (base end part) of the light guide 26 extends in the left-right direction, while the upper part (tip end part) extends in the up-down direction. The lower end face of the light guide 26 is the incident surface 26A and is positioned perpendicular to the left-right direction, while the upper end face of the light guide 26 is the exit surface 26B and is positioned perpendicular to the left-right direction. The outer (left and lower) side of the corner between the lower and upper parts of the light guide 26 is inclined upward as it moves to the left.

[0029] An LED 28 (see Figure 3(B)) is fixed to the left side of the detection substrate 18 near the right side of the incident surface 26A of each light guide 26, and the LED 28 is electrically connected to the control device 20 via the detection substrate 18. The LED 28 emits light (lights up) onto the incident surface 26A of the corresponding light guide 26 on the left, under the control of the control device 20.

[0030] A roughly rectangular box-shaped indicator 30, which serves as a lighting element, is fixed to the upper part of the rear portion of the lampshade 24. The indicator 30 has an open bottom and its top surface is exposed above the console. Multiple (seven in this embodiment) displays 32, which serve as lighting elements, are formed on the upper wall of the indicator 30 near the top of the light exit surface 26B of each light guide 26. The displays 32 are made up of letters or symbols to indicate the shift position of the transmission 22, etc., and are made transparent to allow light to pass through.

[0031] A roughly rectangular box-shaped P-switch 34 (park switch, see Figure 3(A) and (B)) is mounted on the upper side of the front portion of the lampshade 24 as an operating member, and the lower portions of the lower and rear surfaces of the P-switch 34 are open. The P-switch 34 is fitted into the front portion of the lampshade 24 and is movable in the vertical direction within a predetermined range. A cross-shaped columnar pressing column 34A (see Figure 5(B)) is integrally provided on the lower surface of the upper wall of the P-switch 34, and the pressing column 34A extends downward. The pressing column 34A penetrates the upper wall of the lampshade 24 so as to be movable in the vertical direction, and the lower surface of the pressing column 34A is inclined to the right as it goes upward.

[0032] Inside the housing 12, a roughly trapezoidal columnar connecting column 36 (see Figure 5(A)) is provided below the P switch 34 as a connecting member, and the connecting column 36 is movable within a predetermined range in the left-right direction. The left surface of the connecting column 36 is inclined to the right as it extends upward, and the lower surface of the pressing column 34A of the P switch 34 is in surface contact with the left surface of the connecting column 36. A pair of cylindrical connecting rods 36A are integrally provided on the right surface of the connecting column 36 as a connecting part, and the connecting rods 36A extend to the right. A roughly cylindrical biasing cylinder 38 is fixed coaxially to the connecting rods 36A as a biasing part, and the biasing cylinder 38 has elasticity. The biasing cylinder 38 is in elastic contact with the detection substrate 18, and the biasing force of the biasing cylinder 38 moves the connecting rods 36A and the connecting column 36 to the left, and moves the pressing column 34A and the P switch 34 upward. A switch element (not shown) serving as an operation detection unit is fixed to the left side of the detection board 18, to the right of the connecting rod 36A. The switch element is electrically connected to the control device 20 via the detection board 18.

[0033] The upper surface of the P switch 34 is exposed above the console, and the P switch 34 can be pressed downward by the occupant. When the P switch 34 is pressed downward, the P switch 34 and the pressing column 34A move downward against the biasing force of the biasing cylinder 38, and the connecting column 36 and the connecting rod 36A move to the right, causing the switch element to be pressed by the connecting rod 36A (the downward movement of the P switch 34 is detected by the switch element), and the shift position of the transmission 22 is changed to the P position (park position) under the control of the control device 20. On the upper wall of the P switch 34, above the emission surface 26B of the light guide 26, a display 32 similar to the indicator 30 is formed, and this display 32 shows the shift position (P position) of the transmission 22 in letters.

[0034] Next, the operation of this embodiment will be explained.

[0035] In the shift device 10 configured as described above, the detection board 18 is positioned perpendicular to the rotational width direction (left-right direction) of the lever 14. When the lever 14 is rotated, the rotational position of the lever 14 is detected by the shift sensor on the detection board 18, and the shift position of the transmission 22 is changed to the R position, N position, D position, or M position. Furthermore, when the P switch 34 is pressed downwards, the downward movement of the P switch 34 is detected by the switch element on the detection board 18, and the shift position of the transmission 22 is changed to the P position.

[0036] Furthermore, the LED 28 emits light, which enters the light guide 26 from the incident surface 26A, guides the light, and exits from the exit surface 26B. The light from the exit surface 26B then shines on the display 32 on the upper wall of the indicator 30 and the upper wall of the P switch 34, illuminating the display 32.

[0037] Here, an LED 28 is provided on the detection board 18, and the display 32 is positioned perpendicular to the detection board 18. The direction of light incidence (left) and emission (up) in the light guide 26 are perpendicular, and the display 32 is illuminated by the LED 28. Therefore, even if the LED 28 and the display 32 are not facing each other, it is not necessary to provide an LED 28 (a circuit board on which the LED 28 is provided) separately from the detection board 18, simplifying the configuration, reducing the number of components, making the shift device 10 smaller, and lowering costs. Moreover, the connection structure between circuit boards is not required, further reducing costs.

[0038] Furthermore, the light guide 26 is bent perpendicularly between the incident surface 26A and the exit surface 26B. This allows the incident and exit directions of light in the light guide 26 to be perpendicular with a simple configuration.

[0039] Furthermore, the light from the LED 28 is guided by the light guide 26 to illuminate the display 32. This suppresses a decrease in the brightness illuminating the display 32.

[0040] Furthermore, the shielding tube 24A of the lampshade 24 blocks light leakage from the light guide 26. This limits the leakage of light from the light guide 26.

[0041] Furthermore, shielding tubes 24A are provided between the multiple light guides 26. This limits light leakage between the light guides 26, preventing the display 32 from being illuminated by light from a light guide 26 that does not correspond to it.

[0042] Furthermore, the light guide 26 and the shielding cylinder 24A are integrally molded. This allows for easy manufacturing of both the light guide 26 and the shielding cylinder 24A. Moreover, unlike the case where light leaks from the light guide 26 through the insertion hole in the side wall of the shielding cylinder 24A, the leakage of light from the light guide 26 through the side wall of the shielding cylinder 24A can be limited.

[0043] Furthermore, multiple light guides 26 and multiple shielding tubes 24A are integrally molded. Therefore, unlike the case where a light guide 26 is inserted for each shielding tube 24A, multiple light guides 26 and multiple shielding tubes 24A can be easily manufactured.

[0044] Furthermore, the indicator 32 of the P switch 34 is illuminated by light from the LED 28 via the light guide 26. Therefore, even when the P switch 34 is pressed and moved, the indicator 32 of the P switch 34 can be illuminated.

[0045] In this embodiment, the detection substrate 18 is positioned perpendicular to the rotational width direction of the lever 14. However, the detection substrate 18 may be positioned in a direction that intersects the rotational width direction of the lever 14.

[0046] Furthermore, in this embodiment, the display 32 is positioned perpendicular to the detection substrate 18. However, the display 32 may be positioned non-parallel to the detection substrate 18.

[0047] Furthermore, in this embodiment, the incident and outgoing directions of light in the light guide 26 are perpendicular. However, the incident and outgoing directions of light in the light guide 26 do not need to be parallel.

[0048] Furthermore, in this embodiment, the guide portion is a light guide 26. However, the guide portion may also be an optical fiber.

[0049] In this embodiment, the lever 14 (shift body) is rotated. However, the shift body may also slide (move).

[0050] Furthermore, in this embodiment, the shift device 10 is installed on the console. However, the shift device 10 may also be installed on other parts of the vehicle (such as the instrument panel or steering column). [Explanation of symbols]
