Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 5, the electric one-wheel motorcycle 1 according to the embodiment of the present invention includes one wheel 2, a seat 3, a handle 4, a frame 5, a wheel drive motor 6, a battery 7, and a tilt detector 8. It is equipped with.

The user can release the accelerator operation by releasing the throttle pipe.

The frame 5 has a wheel holding portion 51 that supports the rotation shaft so that the wheel 2 can freely rotate. The wheel holding portion 51 is usually provided with

steps

51A and 51A that allow the user to place both feet. The frame 5 has a seat mounting portion 52 to which the seat 3 is mounted (see FIG. 3 and the like). The seat mounting part 52 is located above the wheel holding part 51.

The frame 5 has a handle coupling portion 53 to which the handle 4 is pivotably coupled. The handle coupling portion 53 is located at the center portion of the frame 5 in a front view (see FIG. 1). Moreover, the handle | steering-wheel coupling | bond part 53 is located ahead of the wheel holding | maintenance part 51 and the seat attachment part 52 (refer FIG. 3 etc.). The rotation shaft in the handle coupling portion 53 is inclined clockwise from the reference direction A in the right side view, that is, backward (see the broken line B in FIG. 3). The reference direction A is a direction indicating a state when the wheel drive motor 6 and the wheel 2 in the operating state do not rotate, and is usually the vertical direction (upward direction). In FIGS. 1 and 3,

reference numerals

44 a and 44 b indicate portions near the center of the handle 4, and

reference numerals

44 c and 44 d indicate fixing brackets that fix the rotation shaft passing through the hollow hole of the handle coupling portion 53.

Preferably, the frame 5 is provided with handle

control spring bodies

54 and 54 between the handle 4 so that a force to return the handle 4 to a position where the electric unicycle 1 is in a straight traveling state acts (see FIG. 1 and the like). reference).

Specifically, the handle

control spring bodies

54 and 54 can be two spring bodies provided at positions on the left and right sides with respect to the center of the frame 5 in a front view. When one of the two handle

control spring bodies

54, 54 contracts with respect to the frame 5, the other extends. Thereby, the force which returns the handle | steering-wheel 4 to the position where the electric unicycle motorcycle 1 will be in a straight traveling state works. As a result, it is possible to prevent the steering wheel 4 from excessively rotating and the center of gravity from moving excessively when the direction is changed, and it is easy to change the direction of the one-wheeled motorcycle 1. Moreover, the structure for that is also simple. In FIG. 1 and the like, a shaft body 44aa is attached to the central portion 44a of the handle 4, and metal fittings 44ab and 44ac are fixed to the shaft body 44aa. Reference numeral 54 </ b> A denotes a flat plate that is a part of the frame 5. Each of the handle

control spring bodies

54, 54 is disposed between the metal fitting 44ab and the flat plate body 54A. Further, the metal fitting 44c restricts the rotation range (swing range) of the handle 4, and the rotation range can be finely adjusted.

The frame 5 can be configured to include a first frame 5a, a second frame 5b, and a connecting shaft 5c as described below. That is, the first frame 5a is provided with the wheel holding portion 51 and the

steps

51A and 51A described above. The second frame 5b is provided with the seat mounting portion 52 and the handle coupling portion 53 described above.

The first frame 5a and the second frame 5b are rotatably coupled to each other at inter-frame coupling portions 55 and 55 '. The

inter-frame coupling portions

55 and 55 ′ are located at the central portion of the frame 5 in front view, that is, directly above the wheels 2 (see FIG. 1). The rotation axes of the inter-frame coupling portions 55, 55 'are inclined clockwise from the reference direction A, that is, rearward in the right side view (see broken line C in FIG. 3).

Further, the first frame 5a is provided with a first connection shaft coupling portion 56 in which one end of the connection shaft 5c is rotatably coupled (see FIG. 3 and the like). The handle 4 is provided with a second connection shaft coupling portion 45 in which the other end of the connection shaft 5c is rotatably coupled (see FIG. 5). The connecting shaft 5c is indicated by a broken line DD on a center line (FIGS. 5 and 6) extending in the front and rear direction of the frame 5. ). That is, one of the first coupling shaft coupling portion 56 and the second coupling shaft coupling portion 45 is located on the right side with respect to the center line of the frame 5 and the other side on the left side with respect to the center line of the frame 5 in front view. 5 and 6, the first connecting shaft coupling portion 56 is located on the right side with respect to the center line of the frame 5, and the second coupling shaft coupling portion 45 is located on the left side with respect to the center line of the frame 5.

In the electric unicycle 1 in which the frame 5 includes the first frame 5a, the second frame 5b, and the connecting shaft 5c, when the user rotates the handle 4 clockwise (clockwise) during driving, the connecting shaft 5c rotates clockwise around the first connecting shaft coupling portion 56, and the second frame 5b pivots clockwise around the interframe coupling portions 55, 55 '(FIGS. 2 and 5). Since the rotation axes of the

inter-frame coupling portions

55 and 55 ′ are inclined rearward, when the second frame 5b rotates clockwise around the

inter-frame coupling portions

55 and 55 ′, the second frame 5b is Tilt so that the right side (right side as viewed from the user) is down. Therefore, since the user's center of gravity is on the right side, the electric unicycle 1 changes direction to the right.

When the user rotates the handle 4 counterclockwise (counterclockwise) during operation, the connecting shaft 5c rotates counterclockwise around the first connecting shaft coupling portion 56, and the second frame. 5b rotates counterclockwise around the

inter-frame coupling portions

55, 55 ′ (see FIGS. 2 and 5). Since the rotation axes of the

inter-frame coupling portions

55 and 55 ′ are inclined rearward, when the second frame 5b rotates counterclockwise around the

inter-frame coupling portions

55 and 55 ′, the second frame 5b Tilts so that the left side (left side as viewed from the user) is down. Therefore, since the center of gravity of the user is on the left side, the electric unicycle 1 changes direction to the left.

Since the degree of inclination of the second frame 5b depends on the degree of rotation of the handle 4, the user can rotate the handle 4 so as not to move the center of gravity excessively. it can. Moreover, the structure which has the 1st flame | frame 5a, the 2nd flame | frame 5b, and the connection shaft 5c is simple.

In the configuration having the first frame 5a, the second frame 5b, and the connecting shaft 5c, the first frame 5a and the handle

control spring bodies

54, 54 may be used instead of or together with the handle

control spring bodies

54, 54 described above. A connecting shaft control spring body may be provided between the connecting shaft 5c and the connecting shaft 5c so that a force for returning the handle 4 to a position where the electric one-wheeled motorcycle 1 is in a straight traveling state acts.

The wheel drive motor 6 rotates the wheel 2. Like the general in-wheel motor, the wheel drive motor 6 is provided with a coil on the rotation shaft of the wheel 2 and fixed to the wheel holding portion 51, a magnet is provided outside the rotation shaft, and the magnet rotates together with the wheel 2. To be able to.

Battery 7 supplies power to wheel drive motor 6. The type of the battery 7 is not limited, but can be typically a lithium ion battery. The battery 7 is not limited in its mounting location, but can be detachably attached to the frame 5 as shown in FIG. Further, the battery 7 can supply power to a gyro sensor 81 (to be described later) of the inclination detector 8. In addition, switches for bringing the wheel drive motor 6 and the gyro sensor 81 into an operating state can be appropriately provided.

As shown in FIGS. 7 and 9, the inclination detector 8 has a gyro sensor 81 and an inclination mechanism 82, and is fixed to the frame 5 (specifically, the second frame 5b) at the inclination detector base 80. Has been.

The jello sensor 81 transmits a detection signal corresponding to the inclination θ (forward inclination θ) of the jello sensor 81 from the reference direction A described above to the wheel drive motor 6, and the wheel drive motor 6 (specifically, the detection signal) The rotation of the rotor is controlled. 8 and 10 to 12, the direction in which the jaro sensor 81 faces is indicated by the symbol E. The reference direction A is a direction in which the jello sensor 81 faces when the wheel drive motor 6 and the wheel 2 in the activated state do not rotate (see FIGS. 7 and 9), and is normally the vertical direction as described above. Then, when the posture control is performed so that the user sitting on the seat tilts forward while maintaining balance, the center of gravity moves, and the jaro sensor 81 tilts forward from the reference direction A together with the frame 5 (see FIGS. 8 and 10). The drive motor 6 and the wheel 2 are rotated faster. On the other hand, if the user sitting on the seat controls the posture so as to raise his / her body from the forward tilted state while balancing, the center of gravity moves, the inclination θ of the gyro sensor 81 from the reference direction A decreases, and the wheel drive The rotation of the motor 6 and the wheel 2 is slow. In FIG. 7, reference numeral 81a denotes a substrate that is housed in a case in the gyro sensor 81 and on which a gyro sensor element and a circuit element are mounted, and reference numeral 81A denotes a gyro sensor 81 and the wheel drive motor 6 (and The wiring cable for connecting the battery 7) is shown.

Thus, by providing the jaro sensor 81, the user can change the speed of the electric unicycle 1 by body posture control.

The tilt mechanism unit 82 can change the tilt θ of the gyro sensor 81 according to the brake operation of the brake operation unit 42 and the accelerator operation of the accelerator operation unit 43 separately from the posture control by the user. By the brake operation of the brake operation unit 42 and the accelerator operation of the accelerator operation unit 43, changes in the inclination θ can be reversed.

Specifically, as shown in FIG. 9A, the tilt mechanism portion 82 may have a structure having a first arm 82a and a second arm 82b. The gyro sensor 81 is fixed to the second arm 82b.

The first arm 82a is attached at one end together with the first arm spring body 82c so as to be rotatable to the frame 5 via the inclination detector base 80. When the first arm 82a rotates, a restoring force is generated in the first arm spring body 82c in a direction to return it to the original position (reference position of the first arm 82a). In FIG. 9A, reference numeral 82 e denotes a metal fitting for attaching the one end portion of the first arm 82 a and the first arm spring body 82 c to the inclination detector base 80. Reference numeral 82f denotes a stopper that determines the reference position of the first arm 82a.

The tip of the accelerator wire 43A is connected to the other end of the first arm 82a. In FIG. 9B, reference numeral 82g indicates that the tip end portion of the accelerator wire 43A is connected to the other end portion of the first arm 82a, and one end portion of the second arm 82b and the second arm spring body as will be described later. The metal fitting which attaches 82d to the other end part of the 1st arm 82a is shown.

The second arm 82b is attached to one end of the second arm 82b together with the second arm spring body 82d so as to be rotatable to the other end of the first arm 82a. When the second arm 82b rotates, a restoring force is generated in the second arm spring body 82d in a direction to return it to the original position (the reference position of the second arm 82b with respect to the first arm 82a). In FIG. 9A, reference numeral 82h denotes a stopper that determines the reference position of the second arm 82b with respect to the first arm 82a.

The tip of the brake wire 42A is connected to the other end of the second arm 82b. In FIG. 9B, reference numeral 82i indicates a metal fitting for connecting the tip end portion of the brake wire 42A to the other end portion of the second arm 82b.

By using the tilt mechanism portion 82 having the first arm 82a and the second arm 82b, the following gyro sensor 81 can be operated. That is, in the electric one-wheeled motorcycle 1 (see FIG. 10) that is in the forward state due to the forward tilt of the user (see FIG. 10), the brake operation unit 42 is braked so as to decelerate (in the figure, the tip of the brake wire 42A is on the left side). 11 (a), the second arm 82b rotates with respect to the first arm 82a, and the inclination θ of the jaro sensor 81 increases momentarily, and the wheel drive motor 6 and the wheel 2 are moved. Rotation of will be faster for a moment. Then, the user and the frame 5 get up, and as shown in FIG. 11 (b), the inclination θ of the jaro sensor 81 becomes small, and the electric unicycle 1 is decelerated.

Further, when the accelerator operation unit 43 is operated so as to accelerate (in the drawing, the tip end portion of the accelerator wire 43A moves to the left side), as shown in FIG. 12A, the first arm 82a rotates. Then, the inclination θ of the jaro sensor 81 decreases for a moment, and the rotation of the wheel drive motor 6 and the wheel 2 decreases for a moment. Then, the user and the frame 5 tilt forward, and as shown in FIG. 12B, the tilt θ of the jaro sensor 81 increases and the electric motorcycle 1 accelerates.

Thus, by changing the inclination of the gyro sensor 81 according to the brake operation of the brake operation unit 42 and the accelerator operation of the accelerator operation unit 43, the speed is changed through the posture of the user and the movement of the center of gravity. This prevents excessive movement of the center of gravity so as not to overturn when the brake is operated and the accelerator is operated. Also, the structure is simple.

In addition, a displacement measuring sensor for measuring the rotation displacement of the first arm 82a of the tilt mechanism 82 is provided in order to more precisely control the rotation of the wheel drive motor 6 and the wheel 2 according to the brake operation or the accelerator operation. Or by providing a displacement measurement sensor for measuring the displacement of the throttle pipe rotation of the accelerator operation unit 43 to control the wheel drive motor 6 more precisely while interlocking with the operation of the tilt mechanism unit 82. Can do.

As mentioned above, although the electric unicycle which is embodiment of this invention was demonstrated, this invention is not restricted to what was described in embodiment, Various design changes within the range of the matter described in the claim are carried out. Is possible. For example, it is possible not to have an accelerator operation function.
