Description

TECHNICAL FIELD

[0001] The present application relates to a column structure. BACKGROUND

[0002] A holding mechanism that holds a display provided in a vehicle cabin is disclosed in Japanese Patent Application Publication No. 2024-46633. In addition, the display held by the holding mechanism is disposed opposite a driver of the vehicle. SUMMARY

[0003] However, in the structure described in Japanese Patent Application Publication No. 2024-46633, when the driver of the vehicle adjusts the position of the steering wheel, the relative positional relationship between the steering wheel and the display changes. As a result, it is considered that the visibility of the display by the driver changes.

[0004] In view of the above, an object of the present application is to obtain a column structure that can suppress changes in the relative positional relationship between a steering wheel and a display.

[0005] The column structure of the first aspect includes a display that displays information and faces the driver's seat side of the vehicle; a steering wheel that is disposed on the driver's seat side relative to the display and is operated by an occupant seated on the driver's seat; a column that supports the steering wheel in a manner that allows the steering wheel to displace in the vehicle up-and-down direction and the vehicle front-and-back direction; a combination lever main body that is provided to the column and displaces in the vehicle up-and-down direction and the vehicle front-and-back direction as the steering wheel displaces in the vehicle up-and-down direction and the vehicle front-and-back direction; and a display support portion that has a front base portion that is supported so as to be able to tilt in the vehicle up-and-down direction with the opposite side of the steering wheel as a center of rotation, a rear base portion that supports the display and is supported so as to be able to displace in the vehicle front-and-back direction along the front base portion, and a support arm portion that connects the rear base portion and the combination lever main body.

[0006] In the first type of steering column structure, the steering wheel is supported by the steering column so as to be displaceable in the vehicle up-and-down direction and the vehicle front-and-rear direction. In addition, a combined lever main body is provided in the steering column in connection with the support arm portion of the display support portion. Here, when the steering wheel is displaced in the vehicle up-and-down direction, the combined lever main body is also displaced in the vehicle up-and-down direction. Thus, the front base portion constituting the display support portion tilts in the vehicle up-and-down direction together with the rear base portion. As a result, the display is able to be displaced in the vehicle up-and-down direction in a manner following the displacement of the steering wheel in the vehicle up-and-down direction. On the other hand, when the steering wheel is displaced in the vehicle front-and-rear direction, the combined lever main body is also displaced in the vehicle front-and-rear direction. Thus, the rear base portion constituting the display support portion is displaced in the vehicle front-and-rear direction with respect to the front base portion. As a result, the display is able to be displaced in the vehicle front-and-rear direction in a manner following the displacement of the steering wheel in the vehicle front-and-rear direction. In this way, in the first type of steering column structure, the relative positional relationship between the steering wheel and the display is able to be inhibited from changing.

[0007] In the second type of steering column structure, the front base portion and the rear base portion constituting the display support portion are configured as a cover member that covers the steering column from the vehicle upper side. Thus, a reduction in the appearance quality due to the steering column being visually confirmed from the vehicle upper side is able to be inhibited.

[0008] In the second type of steering column structure, the front base portion and the rear base portion constituting the display support portion are configured as a cover member that covers the steering column from the vehicle upper side. Thus, a reduction in the appearance quality due to the steering column being visually confirmed from the vehicle upper side is able to be inhibited.

[0009] The steering column structure of the present application has the excellent effect of being able to inhibit the relative positional relationship between the steering wheel and the display from changing. BRIEF DESCRIPTION OF DRAWINGS

[0015] Hereinafter, the steering column structure according to an embodiment of the present invention will be described with reference to the accompanying drawings. Furthermore, in each figure, arrow FR appropriately indicates the front side of the vehicle, and arrow UP indicates the upper side of the vehicle. Additionally, in the following description, unless otherwise specified, the directions of front-back, up-down, and left-right refer to front-back in the front-back direction, up-down in the up-down direction, and left-right in the left-right direction (vehicle width direction).

[0016] like Figure 1 As shown, a display 12 and a steering wheel 14 (see reference) are provided around the steering column 10, which uses the steering column structure of this embodiment. Figure 2 ), combined rod body 16 and display support part 18.

[0017] The steering column 10 is configured to include a steering column body 20 and a steering support member 22 supported on the steering column body 20. The steering support member 22 protrudes toward the driver's seat side (rear side) relative to the steering column body 20. Furthermore, a steering wheel 14 (see reference) is fixed to the front end (rear end) of the steering support member 22 in the protruding direction. Figure 2 Furthermore, the amount of rearward protrusion of the steering support member 22 relative to the steering column body 20 can be adjusted. A supported portion 24 is provided at the front end of the steering column body 20. Additionally, a support member 26 is provided on the upper side of the steering column body 20, mounted in the left-right direction in front of the driver's seat. Moreover, the supported portion 24 is supported by the support member 26 in a manner that allows rotation in the left-right direction as the axis of rotation, thereby enabling the steering column 10 to tilt in the vertical direction.

[0018] The display 12 displays various information, such as vehicle-related information and map information. The display 12 is supported by the display support 18, which will be described later, when facing the driver's seat.

[0019] The steering wheel 14, supported by the aforementioned steering column 10, is positioned on the driver's side closer to the display 12. This steering wheel 14 is operated by the occupant seated in the driver's seat, thereby changing the vehicle's direction of travel. Furthermore, the vertical position of the steering wheel 14 is adjusted by tilting the steering column 10 vertically. Moreover, the longitudinal position of the steering wheel 14 is adjusted by displacing the steering support member 22 relative to the steering column body 20 in a forward / backward direction.

[0020] The main body 16 of the combination rod is fixed to the steering wheel 14 side of the steering support component 22. As a result, the main body 16 of the combination rod and the steering support component 22 are displaced together.

[0021] The display support 18 is positioned above the support member 26. The display support 18 is configured to include: a front base 30 and a rear base 32, forming a cover member 28 that covers the steering column 10 from above; a telescopic portion 34 disposed between the front base 30 and the rear base 32; and a support arm 36 extending from the rear base 32 toward the assembly rod body 16. A supported portion 38 is provided at the front end of the front base 30. Furthermore, the supported portion 38 is rotatably supported on the support member 26 with the left-right direction as its rotation axis, allowing the display support 18 to tilt vertically. The rear base 32 is supported by the front base 30 via the telescopic portion 34. The display 12 is fixed to the rear end of the rear base 32. Moreover, the telescopic portion 34 operates to change the position of the rear base 32 relative to the front base 30 in the front-rear direction. The support arm 36 connects the rear base 32 to the assembly rod body 16. The end of the support arm 36 opposite to the rear base 32 is formed into a spherical ball joint 40. Furthermore, the ball joint 40 is spherically supported on a portion of the combined rod body 16. Additionally, the portion of the support arm 36 corresponding to the ball joint 40 can also be supported by a portion of the combined rod body 16 to allow for axial rotation in the left-right direction.

[0022] The function and effects of this implementation method

[0023] Next, the function and effects of this embodiment will be explained.

[0024] In the embodiment described above, when the steering wheel 14 is... Figure 2 When the position shown shifts downwards, the main body 16 of the composite rod shifts downwards. That is, as... Figure 2 and Figure 3 As shown, when the steering column 10 is tilted downwards, the combined rod body 16 is displaced downwards.

[0025] When the main body 16 of the combination lever moves downward, the display support 18 tilts downward. As a result, the display 12 can be moved downward in a manner that follows the downward movement of the steering wheel 14. Furthermore, when the steering wheel 14 is moved from... Figure 3 Similarly, when the position shown is displaced upwards, the display 12 can be displaced upwards in a manner that follows the upward displacement of the steering wheel 14.

[0026] Additionally, when the steering wheel 14 is turned from... Figure 2When the position shown shifts forward, the main body 16 of the composite rod shifts forward. That is, as... Figure 2 and Figure 3 As shown, when the steering support component 22 is displaced forward relative to the steering column body 20, the combined rod body 16 is displaced forward.

[0027] When the main body 16 of the combination lever moves forward, the telescopic part 34 operates, and the rear base part 32 moves forward relative to the front base part 30. As a result, the display 12 can be moved forward in a manner that follows the forward movement of the steering wheel 14. Furthermore, when the steering wheel 14 is moved from... Figure 3 Similarly, when the position shown is displaced to the rear, the display 12 can be displaced to the rear in a manner that follows the rearward displacement of the steering wheel 14.

[0028] As explained above, in this embodiment, changes in the relative positional relationship between the steering wheel 14 and the display 12 can be suppressed.

[0029] Furthermore, in this embodiment, the front base portion 30 and the rear base portion 32 constituting the display support portion 18 become a cover member 28 that covers the steering column 10 from above. This suppresses any reduction in appearance quality caused by the steering column 10 being visually inspected from above.

[0030] Furthermore, although this embodiment describes an example where the front base portion 30 and the rear base portion 32 are configured as a cover member 28 that covers the steering column 10 from above, the present invention is not limited thereto. For example, in structures that provide other components that cover the steering column 10 from above, it is also possible to use a structure in which the front base portion 30 and the rear base portion 32 are not configured as cover members 28.

[0031] The present invention has been described above as one embodiment, but the present invention is not limited to the above description. It is natural that various modifications other than those described can be made without departing from its spirit.
