This application claims priority under 35 USC 119 from Japanese Patent Application No. 2017-120459 filed Jun. 20, 2017, the disclosure of which is incorporated by reference herein in its entirety.
The present disclosure relates to a shift device in which a shift body is rotated to change a shift position of the shift body.
In a shift operation device described in the pamphlet of International Publication (WO) No. 2015/107592, a knob is rotated to change a shift position of the knob.
In such a shift operation device, it would be preferable to be able to guide liquid (for example a drink) that has entered the knob.
In consideration of the above circumstances, the present disclosure obtains a shift device capable of guiding liquid that has entered a shift body.
A shift device for a vehicle of a first aspect of the present disclosure includes a shift body and an entry path. The shift body is rotated to change a shift position. The entry path is provided at the shift body, and extends along an outer peripheral side, in a rotation circumferential direction of the shift body. Liquid is able to enter the entry path.
A shift device of a second aspect of the present disclosure is the shift device of the first aspect of the present disclosure, further including a drainage section and a drainage groove. The drainage section is provided at the entry path, and includes an outlet through which liquid that has entered the entry path is able to drain. The outlet faces an outer peripheral side of the entry path. The drainage groove is provided at the entry path and extends toward a drainage section side.
A shift device of a third aspect of the present disclosure is the shift device of the second aspect of the present disclosure, wherein the drainage groove extends to the drainage section.
A shift device of a fourth aspect of the present disclosure is the shift device of the second aspect or the third aspect of the present disclosure, wherein the drainage groove extends as far as the outlet of the drainage section.
A shift device of a fifth aspect of the present disclosure is the shift device of the first aspect of the present disclosure, further including a drainage section, a movement path, and a movement groove. The drainage section is provided at the entry path, and allows a liquid that has entered the entry path to drain through an outlet. The outlet faces an outer peripheral side of the entry path. Liquid drained from the drainage section moves along the movement path. The movement groove is provided at the movement path, and extends along an axial direction of the shift body.
In the shift device of the first aspect of the present disclosure, the shift body is rotated to change a shift position of the shift body.
Note that the liquid entry path extends along the outer peripheral side in the rotation circumferential direction of the shift body, and liquid is able to enter the entry path. Liquid that has entered the shift body can thus be guided by the entry path.
In the shift device of the second aspect of the present disclosure, liquid that has entered the entry path of the shift body is able to drain from the entry path through the outlet of the drainage section.
The entry path is provided with the drainage groove, the drainage groove extending toward the drainage section side. Accordingly, since liquid enters the drainage groove, the liquid can be encouraged to move toward the drainage section side, enabling the liquid that has entered the entry path of the shift body to be effectively drained through the drainage section.
In the shift device of the third aspect of the present disclosure, the drainage groove extends to the drainage section. Accordingly, liquid that has entered the drainage groove can be encouraged to move toward the drainage section, enabling the liquid that has entered the entry path of the shift body to be effectively drained through the drainage section.
In the shift device of the fourth aspect of the present disclosure, the drainage groove extends as far as the outlet of the drainage section. This thereby enables liquid that has entered the drainage groove in the drainage section to be encouraged to move, enabling the liquid that has entered the entry path of the shift body to be effectively drained through the outlet of the drainage section.
In the shift device of the fifth aspect of the present disclosure, liquid that has entered the entry path of the shift body is able to drain through the drainage section of the entry path, and the liquid drained through the drainage section moves along the movement path.
Note that the movement groove is provided in the movement path, and the movement groove extends along the axial direction of the shift body. This thereby enables liquid that has entered the movement groove of the movement path to be encouraged to move, enabling the liquid that has been drained from the shift body to be effectively drained through the movement path.
An exemplary embodiment will be described in detail based on the following figures, wherein:
The shift device 10 according to the present exemplary embodiment is installed to a console (vehicle body side) of a vehicle, and is disposed at a vehicle front side and vehicle width direction inner side of a driver's seat (not illustrated in the drawings) of the vehicle. The front, right, and upper side of the shift device 10 respectively face an oblique front upper side of the vehicle, the right of the vehicle, and an oblique rear upper side of the vehicle.
As illustrated in
A panel 20 that has a bottomed cylindrical shape and that serves as a display member configuring the installed body is fixed inside the support cylinder 14 at an upper side of the plate 12. The panel 20 is disposed coaxially with the support cylinder 14, and passes through the console such that an upper face (base face) of the panel 20 is exposed to a vehicle cabin interior.
A substantially rectangular box shaped housing 22, serving as a covering member configuring the installed body, is fixed to the upper side of the plate 12. The interior of the housing 22 is open toward a lower side, and the housing 22 covers the upper side of the plate 12. An upper wall of the housing 22 is formed with a pierced cylinder 22A that has a substantially frustoconical tube shape. The interior of the pierced tube 22A is in communication with the interior of the housing 22 at the lower side, and the panel 20 passes coaxially through the interior of the pierced tube 22A.
Substantially rectangular plate shaped movement plates 24 (see
A substantially cylindrical knob 26, serving as a shift body, is supported at the upper side of the plate 12. The knob 26 is disposed coaxially to the support cylinder 14 of the plate 12.
A knob 26 is provided with a substantially cylindrical knob base 26A (see
A drainage frame 30, serving as a drainage section, is integrally formed to the outer periphery of the flow path frame 28. The drainage frame 30 projects toward a radial direction outer side of the flow path frame 28, and an upper side portion of the drainage frame 30 is formed with a rectangular drainage opening 30A configuring the entry path. The drainage opening 30A is open toward an upper side, and opens up the flow path 28A to a radial direction outer side of the flow path frame 28. A lower side portion of the drainage frame 30 configures a rectangular plate shaped drainage plate 30B. The drainage plate 30B extends toward a lower side at a position on a radial direction outer side edge of the flow path frame 28, and is disposed at a radial direction outer side of the support cylinder 14 of the plate 12 (in the movement space 18). A face of the drainage plate 30B on the radial direction outer side of the flow path frame 28 configures a drainage face 30C, and the entry path is configured by the drainage face 30C at the radial direction outer side of the flow path frame 28.
Drainage grooves 32, each having a substantially triangular cross-section profile, are formed at a radial direction inner side edge and radial direction outer side edge of a lower face of the flow path 28A. Each drainage groove 32 extends substantially along the entire circumferential direction of the flow path 28A. Two extension direction end portions of the drainage groove 32 at the radial direction inner side edge of the flow path 28A respectively extend toward a lower face of the drainage opening 30A and intermediate portions in a circumferential direction of the drainage face 30C. The two extension end portions of the drainage groove 32 at the radial direction outer side edge of the flow path 28A respectively extend toward the lower face of the drainage opening 30A and both end portions in the circumferential direction of the drainage face 30C (see
A substantially annular frame shaped first rotary member 26B, serving as a first exposed portion, is fixed to an outer peripheral side of an upper end portion of the knob base 26A so as to be coaxial to and capable of rotating as a unit with the knob base 26A. The first rotary member 26B covers an upper end portion of the pierced tube 22A from the upper side. A substantially annular frame shaped second rotary member 26C, serving as a second exposed portion, is fixed to an upper side of the first rotary member 26B so as to be coaxial to and capable of rotating as a unit with the first rotary member 26B. An upper end of the second rotary member 26C is rotatably fitted to an outer periphery of an upper face of the panel 20.
The first rotary member 26B and the second rotary member 26C pass through the console and are exposed to the vehicle cabin interior. The knob 26 can be operated rotationally within a predetermined range by an occupant of the vehicle (in particular, a driver seated in the driver's seat) using the first rotary member 26B and the second rotary member 26C. Shift positions can be changed by rotating the knob 26 in one direction (the arrow X direction in
When the knob 26 has been disposed at the P position, the drainage opening 30A and the drainage face 30C of the knob 26 (knob base 26A) face toward a front side of the movement plate 24 on the right side of the housing 22 (see
A shift locking mechanism (not illustrated in the drawings), serving as a restriction section, is provided at the upper side of the plate 12, further to a front side from the movement space 18 (for example, at a front side of the knob 26). The shift locking mechanism locks (restricts) rotation of the knob 26 at a predetermined shift position (for example, the P position) at a predetermined stimulus.
A rotation mechanism (not illustrated in the drawings), serving as a rotation section, is provided at the upper side of the plate 12, further toward a front side from the movement space 18 (for example, at the lower side of the knob 26). The rotation mechanism rotates the knob 26 to a given shift position (for example, the P position) at a given stimulus.
Next, explanation follows regarding operation of the present exemplary embodiment.
In the shift device 10 configured as described above, the shift position of the knob 26 is changed to the P position, the R position, the N position, or the D position by rotation operating the knob 26.
The flow path 28A at the outer periphery of the knob 26 (knob base 26A) extends along the circumferential direction of the knob 26. Should a liquid (for example a drink) flow down from an upper side of the shift device 10, the liquid would enter the shift device 10 between the knob 26 and the upper end portion of the pierced tube 22A of the housing 22, and would be capable of entering the flow path 28A. The liquid that has flowed into the shift device 10 from the upper side of the shift device 10 can thus be guided by the flow path 28A.
Moreover, the drainage grooves 32 are formed in the lower face of the flow path 28A of the knob 26. The drainage grooves 32 extend around substantially the entire flow path 28A in the circumferential direction. Accordingly, even if the liquid in the flow path 28A is viscous, for example, since the liquid enters the drainage grooves 32, capillary action facilitates movement of the liquid along the drainage grooves 32. The liquid can thus be encouraged to move toward the drainage frame 30 side of the knob 26 (knob base 26A), enabling the drainage frame 30 to drain the liquid effectively. This thereby enables liquid to be suppressed from collecting in the flow path 28A, enables the liquid in the flow path 28A to be suppressed from scattering when the knob 26 is rotated, and enables the liquid to be suppressed from affecting the shift locking mechanism and the rotation mechanism.
Moreover, the drainage grooves 32 of the flow path 28A extend along the drainage frame 30 (the lower face of the drainage opening 30A, and the drainage face 30C). This enables liquid that has entered the drainage grooves 32 of the flow path 28A to be encouraged to move toward the drainage frame 30, enabling the liquid in the flow path 28A to be even more effectively drained through the drainage frame 30.
Moreover, the drainage grooves 32 extend over the lower face of the drainage opening 30A, and the drainage face 30C, of the drainage frame 30. This thereby enables the liquid that has entered the drainage grooves 32 of the drainage frame 30 to be encouraged to move, enabling the liquid in the drainage frame 30 to be effectively drained through the drainage frame 30.
The liquid drained through the drainage frame 30 (drainage opening 30A and drainage face 30C) of the knob 26 flows down into the movement space 18 in the plate 12. When the knob 26 has been placed at the P position or the D position, the drainage opening 30A and the drainage face 30C of the knob 26 oppose the front side of the right movement plate 24 or the left movement plate 24 of the housing 22.
The movement grooves 24B are formed at the front side of the respective movement plates 24. Each movement groove 24B extends in the up-down direction, and is open at the lower side. Accordingly, even if the liquid drained through the drainage frame 30 is viscous, for example, when the liquid enters the movement grooves 24B, capillary action facilitates movement of the liquid along the movement grooves 24B. This enables the liquid at the front sides of the movement plates 24 to be encouraged to flow down toward the movement space 18, and enables the liquid drained through the drainage frame 30 to be effectively made to flow down into the movement space 18. This thereby enables the liquid to be effectively drained from the movement space 18 to the outside of the shift device 10 through the movement slots 16A in the plate 12 and through gaps between side walls of the housing 22 and the plate 12.
Note that in the present exemplary embodiment, the drainage frame 30 is provided at the flow path frame 28 of the knob 26. However, configuration may be made in which the drainage frame 30 is not provided at the flow path frame 28 of the knob 26, and the entire periphery of the flow path 28A inside the flow path frame 28 is not open at the radial direction outer side.
Moreover, in the present exemplary embodiment, the knob 26 is operated rotationally by an occupant. However, a lever (shift section) may be provided capable of rotating as a unit with the knob 26, such that the knob 26 is rotated by swinging operation of the lever by the occupant
Moreover, in the present exemplary embodiment, the shift device 10 is installed to the console. However, the shift device 10 may be installed to a floor of the vehicle cabin, an instrument panel, or a steering column cover.
