no. 1 approach

[0060] use figure 1 The perspective view is shown to illustrate the structure of the coaxial two-wheeled vehicle of the first embodiment. In this specification, a pitch axis is an axis corresponding to the axles of the pair of wheels 13L, 13R. The roll axis is an axis passing through the center of the vehicle body 12 and parallel to the traveling direction of the vehicle. A yaw (yaw) axis is an axis passing through the center of the vehicle body 12 and perpendicular to the road surface on which the vehicle is running.

[0061] This coaxial two-wheeled vehicle 10 includes: a vehicle body 12 ; wheels 13L, 13R; wheel drive units 14L, 14R; and a turning operation unit 15 .

[0062] The turning operation unit 15 is an operation means for performing a turning operation by tilting it in a roll direction. The turning operation unit 15 includes: a base member 150 ; knee contact portions 151L, 151R; an operating lever 154 ; and an operating lever height adjusting portion 155 .

no. 2 approach

[0100] Compared with the first embodiment of the invention, the second embodiment is characterized in that the turning operation part is formed in a novel shape, and an alighting switch is provided near the handle for getting on and off the turning operation part.

[0101] Figure 7 It is an external perspective view of the coaxial two-wheeled vehicle of the second embodiment. The vehicle body 12 of the coaxial two-wheeled vehicle of this second embodiment has the same structure as that of the first embodiment of the invention, and therefore description thereof will be omitted.

[0102]The turning operation portion 45 has a standing portion 451 having a substantially U-shape when viewed from the front. The upper ends of the vertical pieces 451L, 451R of the standing portion 451 are connected by the handle 452 for getting on and off the vehicle. Further, knee abutment portions 453L, 453R respectively extending rearward are formed continuously on the upper ends of the vertical...

no. 3 approach

[0107] This third embodiment is characterized in that the height of the turning operation portion is lower than that of the first embodiment of the invention.

[0108] Figure 9 It is an external perspective view of the coaxial two-wheeled vehicle of the third embodiment. The vehicle body 12 of the coaxial two-wheeled vehicle of the third embodiment has the same structure as that of the first embodiment of the invention, and therefore description thereof will be omitted.

[0109] The turning operation portion 55 has a ring shape, and its lower end portion is supported so as to be rotatable relative to the vehicle body 12 . Specifically, the turning operation part 55 is integrally formed with the calf contact part 551L, the calf contact part 551R, the carrying handle 552, the lower connection part 553, the quick lever 554L, and the quick lever 554R.

[0110] The calf contact portions 551L and 551R are disposed at positions where they come into contact with each calf of the oc...

Abstract

This coaxial two-wheeled vehicle (10) aims to realize a turning, when a running direction is on a roll axis, by inclining a turning operation unit (15) in the rolling direction. The turning operation unit (15) is arranged between the legs of a rider, and has a nonconstraining structure with respect to the motions of the legs in the longitudinal directions of the vehicle. The turning operation unit (15) is equipped in its portions with knee pads (151L and 151R) and calf pads (551L and 551R) for contacting the knees and calves of the rider thereby to execute the turning operation.

Description

technical field [0001] The present invention relates to a coaxial two-wheeled vehicle having two wheels disposed on the same axial center line, and more particularly to a coaxial two-wheeled vehicle in which a person rides on the vehicle for traveling operation. Background technique [0002] Patent Document 1 discloses an example of a conventional coaxial two-wheeled vehicle. This Patent Document 1 describes a technique related to a vehicle body structure of a coaxial two-wheeled vehicle. In Patent Document 1, a vehicle is provided with left and right separate footboards rotatable in a roll direction, and a handle for changing the posture of the separate floorboards. Thus, the problem of the coaxial two-wheeled vehicle falling sideways due to the action of the centrifugal force when turning and running is solved. In addition, in Patent Document 1, in terms of the structure of the handle, in addition to the type operated by the rider's arm, a coaxial two-wheeled vehicle of ...
