A holder 41 for the battery 40 is arranged behind the step 30 . The holder 41 has a substantially box-like shape with an open front surface, and forms a storage space for the battery 40 therein. More specifically, the holder 41 has a bottom wall and a top wall facing each other and extending substantially horizontally, and a pair of left and right side walls and a rear wall standing between the side walls and the top wall. , the bottom wall is mounted and supported on the upper surface of the rear end of the main frame 21 and the upper surface of the support frame 24 .

A substantially rectangular opening 41 a is provided in the front surface of the holder 41 . A substantially box-shaped battery 40 is inserted into the holder 41 through the opening 41a, thereby supporting the battery 40. As shown in FIG. Although illustration is omitted, the holder 41 is provided with a lock mechanism that holds the battery 40 in a housed state. The top surface of the bottom wall is formed substantially flush with the top surface of the step 30 . As a result, the battery 40 can be easily accommodated (inserted) into the holder 41 or easily removed (separated) from the holder 41 while the battery 40 is slid forward and backward along the upper surface of the step 30 as shown by the arrows in FIG. )be able to. Although not shown, a terminal is provided on the rear wall of the holder 41, and the terminal of the battery 40 is connected to this terminal when the battery 40 is accommodated.

The battery 40 is a secondary battery such as a lithium ion battery that stores electric power to be supplied to the traveling motor 4 . is connected to the traveling motor 4 of the Electric power supplied from the battery 40 to the travel motor 4 is controlled by a power control unit (not shown).

As shown in FIG. 1 , the front frame 10 and the rear frame 20 are connected via the swinging portion 50 . That is, the base frame 17 provided at the rear end portion of the front frame 10 and the main frame 21 provided at the front end portion of the rear frame 20 are connected via the swing portion 50 so as to be capable of swinging in the left-right direction. be. The swinging portion 50 has a Neidhardt rubber spring 51 fixed to the bottom surface of the base frame 17 .

FIG. 6 is a diagram (sectional view taken along line VI-VI in FIG. 1) showing a schematic configuration of the Neidhardt rubber spring 51 provided in the swinging portion 50. As shown in FIG. As shown in FIG. 6, the Neidhardt rubber spring 51 is housed in a case 511 having a substantially rectangular frame shape in cross section and fixed to the bottom surface of the base frame 17 . A shaft 512 that is provided integrally with the main frame 21 of the rear frame 20 and extends along the axis CL3 is arranged in the case 511 . Note that the front end portion of the main frame 21 may be used as the shaft 512 . The Neidhardt rubber spring 51 includes a substantially diamond-shaped cam block 513 spline-connected to the shaft 512 so as to be rotatable integrally with the shaft 512 , and rubber rollers arranged to face concave surfaces of the cam block 513 . 514. FIG. 7 corresponds to the initial state of the swinging portion 50 before swinging.

FIG. 7 is a view of the vehicle 100 viewed from the rear and corresponds to the initial state before rocking. Note that FIG. 7 simply shows the configuration of the vehicle 100 . As shown in FIG. 7, the vertical pipe 11 extends substantially perpendicularly to the road surface 101 in the initial state. The posture of the vehicle 100 in this case is called a reference posture.

From this initial state, torque acts on the case 511 of the swinging portion 50 in FIG. Elastic deformation occurs, and the rubber roller 514 becomes an ellipse. At this time, the front frame 10 shown in FIG. 7 swings in the left-right direction (in the direction of arrow R1 or R2) with respect to the step 30 about the axis CL3, and the vertical pipe 11 inclines with respect to the road surface 101. As shown in FIG. As a result, the vehicle 100 assumes an inclined posture. In this case, as the rotation angle of the case 511 about the axis CL3 increases, the rotational resistance to the case 511 increases. When the torque acting on the case 511 becomes 0, the rubber roller 514 returns to its original shape due to its elastic force, and the front frame 10 returns to the reference posture shown in FIG.

By providing the front frame 10 so as to be able to swing via the swinging portion 50 in this way, the user PS riding in the vehicle 100 in a standing posture can easily turn the vehicle 100 in the left-right direction. For example, when the vehicle 100 turns left and right, the user slightly bends the knees and ankles and tilts the upper body left and right. As a result, the vertical pipe 11 is swung together with the base frame 17 in a stable posture with both feet placed on the step 30 while the step 30 integrated with the rear frame 20 is kept horizontal, and the front wheel 1 is tilted left and right. be able to. As a result, the vehicle 100 can be smoothly turned, and the turning performance is improved.

Further, since the Neidhardt rubber spring 51 is provided in the swinging portion 50, when the front frame 10 is swung left and right from the reference posture, a restoring force acts on the front frame 10, and the swinging of the front frame 10 is suppressed. can be well suppressed. Note that the restoring force may be applied to the front frame 10 by an elastic member such as a coil spring instead of the Neidhardt rubber spring 51 . That is, the configuration of the damper member is not limited to the Neidhardt rubber spring 51 . Furthermore, since the battery 40 is supported by the holder 41 placed on the main frame 21 and the support frame 24, which are non-oscillating members, the moment due to the gravity of the battery 40 does not act in the oscillating direction. It is possible to suppress the overturning of the vehicle 100 when it swings.

Although not shown, the weight of the user in a standing posture acts on the step 30 (the center point of the load acting from the soles of the feet) is the ground contact point of the front wheel 1 and the pair of left and right rear wheels 2 in plan view. Located within the triangular area connecting the respective ground points. As a result, the user can get into the vehicle 100 in a stable posture during both running and stopping. Since the heavy battery 40 is arranged between the left and right rear wheels 2, the center of gravity of the vehicle 100 is lowered, and the parking posture becomes more stable.

In the vehicle 100 according to the present embodiment, as described above, the first frame FL1 is foldably provided with respect to the second frame FL2 about the shaft portion 18a (axis line CL2) of the bracket 18 of the front frame 10. 8A to 8D are diagrams showing an example of a posture change from the running posture of the vehicle 100. FIG. 8A to 8C correspond to the directions shown in FIGS. 1 and 2, respectively. The folded posture is included in the non-running posture of vehicle 100 .

When folding the vehicle 100 from the running posture, first, the lock mechanism of the handle shaft 13 is released, and the handle shaft 13 is retracted to the maximum extent within the vertical pipe 11 as indicated by arrow A1 in FIG. 8A. Next, the lock mechanism of the bracket 18 is released, and the first frame FL1 is rotated rearward about the axis CL2 with respect to the second frame FL2 as indicated by the arrow A2. Thereby, the vehicle 100 is folded as shown in FIG. 8B. The handle 14 abuts on the holder 41 in the folded posture in which the first frame FL1 is rotated rearward to the maximum. More specifically, the rear surface of the central portion of the handle 14 in the running posture (FIG. 8A) abuts the upper surface of the upper wall of the holder 41 . In this state, the vertical pipe 11 and the main frame 21 are substantially parallel, and the battery 40 is arranged between the front and rear frames 10 and 20 .

Further, as indicated by arrow B1 in FIG. 8B, front wheel 1 is lifted upward with rear wheel 2 as a fulcrum. As a result, as shown in FIG. 8C, the main frame 21 is raised and the vehicle 100 can be raised. At this time, the pair of left and right rear wheels 2 and the tip portions of the pair of left and right stands 141 provided on the handle 14 come into contact with the road surface 101 . Accordingly, the vehicle 100 can be stably self-supported at four points and set in a standing posture. At this time, the display unit 140 and the headlight 142 are positioned above the road surface 101 . Therefore, the display unit 140 and the headlight 142 are protected by the stand 141. FIG.

A handle 19 is provided on the bracket 18 so as to be rotatable coaxially with the shaft portion 18a. When transporting the vehicle 100 from the state of FIG. 8C, the handle 19 is turned upward as indicated by the arrow C1 in FIG. 8C, and the user PS grips the handle. In this state, as shown in FIG. 8D, the vehicle 100 is tilted forward with the rear wheels 2 as fulcrums. Accordingly, the vehicle 100 can be easily transported while rolling the rear wheels 2 on the road surface 101 . In this case, since the display unit 140 and the headlight 142 are arranged inside the pair of left and right stands 141, the display unit 140 and the headlight 142 can be prevented from colliding with an obstacle from the side during transportation of the vehicle. can be protected. In addition, since the display unit 140 faces downward when the vehicle 100 is in the transportation posture, the display unit 140 can be protected against collision with an obstacle from behind. Furthermore, since the handle 14 is in contact with the holder 41 in the transport posture, the battery 40 can be prevented from being damaged by collision with an obstacle.

FIG. 9 is a diagram showing an example of a posture of vehicle 100 during storage. As shown in FIG. 9, the vehicle 100 is stored in an upright posture. In this state, the handle 42 provided on the battery 40 is grasped, and the battery 40 is lifted and removed from the holder 41 as indicated by an arrow A1 in FIG. Battery 40 is then connected to a charger outside vehicle 100 and charged. Even when vehicle 100 is stored, vehicle 100 is stably held in an upright posture by left and right rear wheels 2 and a pair of left and right stands 141, as in FIG. 8C. Therefore, it is possible to easily attach and detach the battery 40 for charging the battery 40 .

According to this embodiment, the following effects can be obtained.

When the first frame FL1 is rotated toward the second frame FL2 via the shaft portion 18a, that is, when the handle 14 is in a folded posture, and when the second frame FL2 is raised with the rear wheel 2 as a fulcrum, the handle 14 is rotated. That is, it has a stand 141 that touches the ground together with the rear wheel 2 when it is in a standing posture (Fig. 8C).

Accordingly, with a simple configuration, the vehicle 100 can be made to stand on its own in a stable state in the folded posture. In a state in which the vehicle 100 is folded and stood up, the overall length in the front-rear direction and the overall length in the vertical direction can be shortened. Therefore, the installation space can be suppressed and the vehicle 100 can be stored efficiently.

Thereby, the stand 141 can be provided without deteriorating the visibility of the display unit 140 by the user PS. In addition, the stand 141 can protect the display unit 140 from lateral obstacles.

(4) Vehicle 100 further includes a headlight 142 arranged between a pair of left and right stands 141 (FIG. 3). As a result, the stand 141 does not block the light of the headlamp 142, and the stand 141 can protect the headlamp 142 from side obstacles.

(5) The display unit 140 is arranged behind the front ends and below the upper ends of the pair of left and right stands 141 in the running posture of the vehicle 100 (FIGS. 1 and 3). Thus, when the vehicle 100 is transported in a folded posture (FIG. 8D), the stand 141 can protect the display unit 140 from obstacles above and behind.
