  However, the coaxial two-wheeled vehicle described in Patent Document 1 has a problem in that the structure is complicated, and a region where a control board, a sensor, and the like are mounted is limited due to the movable region of the link structure of the vehicle main body.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a coaxial two-wheeled vehicle that achieves both securing of a mounting area of a vehicle main body and stable turning operation.

A coaxial two-wheeled vehicle according to the present invention includes two step plates provided on both sides with respect to a direction orthogonal to the traveling direction for a driver to board, a vehicle main body that supports the step plate, and a direction orthogonal to the traveling direction. A pair of wheels that are coaxially arranged in a direction to be rotated and supported so as to be rotatable with respect to the vehicle main body, and driving means for independently driving the pair of wheels. The vehicle body portion, the vehicle body upper member and the vehicle body lower member provided in parallel to the ground, the while being connected to the step plate, is pivotally connected with the vehicle body upper member and the car body lower member A pair of side members, and a pair of lower sliding fulcrums of the vehicle body lower member and the pair of side members in the link mechanism is the width of each wheel as viewed in the vehicle traveling direction. A pair of upper swing fulcrums of the vehicle body upper member and the pair of side members in the link mechanism are respectively disposed at the center positions, and are disposed inside the pair of lower swing fulcrums in the vehicle width direction; And it is arrange | positioned in the space inside the said pair of wheel . Thereby, the mounting area of the vehicle main body can be further expanded, and the turning operation of the coaxial two-wheeled vehicle can be stabilized.

  ADVANTAGE OF THE INVENTION According to this invention, the coaxial two-wheeled vehicle which made the securing of the mounting area | region of a vehicle main-body part and the stability of turning operation | movement compatible can be provided.

Embodiment 1
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of a coaxial two-wheeled vehicle 1 according to an embodiment. The coaxial two-wheeled vehicle 1 includes a vehicle main body 10, a step 11, a mounted device 12, wheels 13, a handle 14, and a grip 15.

  Step 11 is for the driver to board and is divided into two on the left and right with respect to the traveling direction of the coaxial two-wheeled vehicle.

  The mounted device 12 is mounted inside the vehicle main body 10 and includes a motor that operates the wheel 13, a sensor for detecting the attitude of the coaxial two-wheel vehicle 1, a sensor for detecting the displacement of the link, and the like.

  The wheels 13 are coaxially arranged in a direction orthogonal to the traveling direction, and are supported so as to be rotatable with respect to the vehicle body 10.

  FIG. 2 is a diagram showing an outline of the vehicle main body. The vehicle main body 10 includes a vehicle body upper member 101, a vehicle body lower member 102, and side members 103 and 104.

The vehicle body upper member 101 and the vehicle body lower member 102 are provided in parallel and each have a plate shape. The side members 103 and 104 are provided in parallel and have a plate shape. The vehicle body upper member 101 is rotatably connected to the side members 103 and 104 via the shaft 106.
The vehicle body upper member 101 is connected to the step 11 via the shaft 106.

Car body lower member 102 is pivotally connected via the side members 103 and 104 and the shaft 107. Thereby, the vehicle main body 10 has a four-link structure. The shaft 107 is configured to be the center of the width of the wheel 13.

  FIG. 2B is a view for explaining the link structure of the vehicle main body. As shown in FIG. 2B, the four-link structure of the vehicle main body 10 has one degree of freedom and swings with the shaft 107 as a swing fulcrum.

  The side members 103 and 104 are connected to the step 11. As shown by the broken line in FIG. 2A, when step 11 tilts, that is, when the coaxial two-wheel vehicle 1 performs a turning operation, the side members 103 and 104 also tilt according to the tilt of step 11.

  In the coaxial two-wheeled vehicle 1 according to the embodiment, a shaft 107 that is a swing fulcrum of the vehicle main body 10 is provided at a position that is the center of the width of the wheel 13. As a result, when the driver gets on the step 11, the shaft 107, which is the swing fulcrum of the vehicle main body 10, can be laid out outside the passenger's heel, which is stable even in the turning operation of the coaxial two-wheeled vehicle. Can be operated. Further, the height of the step can be set to the minimum, thereby making it more compact.

  Furthermore, since the mounted device 12 can be disposed on the lower body member 102, the mounting area can be increased. In addition, this can reduce the price and make it highly reliable.

  FIGS. 3A and 3B are views showing a modification of the vehicle main body 10 according to the present embodiment. FIG. 3A shows a configuration in which the amount of displacement in step 11 is reduced and the coaxial two-wheeled vehicle 1 operates more sensitively to the inclination in step 11. Here, step 11 and peristaltic fulcrum 107 are brought close to each other. Since the coaxial two-wheel vehicle 1 measures the displacement of the peristaltic link and gives a turning instruction, this makes it more sensitive to the operation of the driver.

  FIG. 3B shows a trapezoidal 4-link structure of the vehicle body 10. In this configuration, instead of the mechanical stopper, it is carried by a link specific posture. With this configuration, the displacement amount of the step on the operation input side can be made larger than the displacement amount of the other step.

  Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.
