The speed control circuit 25 includes a variable resistor B1 for determining the maximum speed of the electric vehicle 1, a variable resistor B2 that is varied in conjunction with the accelerator lever 22, and a reversing switch SW2 and a reversing state of the steering wheel. Handle position detection switch SW1 is connected. Further, an encoder E for counting the rotation speed of the electric motor M is connected to the speed control circuit 25. The speed control circuit 25 drives the electric motor M via the inverter circuit 26 by well-known PWM control.
The electric motor M can be rotated in a rotation direction according to the operation of W2 and at a speed according to the operation angle of the accelerator lever 22.

FIG. 8 is a flowchart showing a software configuration of the speed control circuit 25 for controlling the operation mode of the truck mode according to the main part of the present invention. First, CPU
Reads the state of the handle position detection switch SW1 to determine whether the handle 12 is tilted forward on the opposite side of the seat 7 (steps S1 and S2). Here, when the steering wheel 12 is tilted toward the seat 7, the vehicle is controlled to run in the normal mode, and when the steering wheel 12 is tilted forward, the vehicle is controlled to run in the bogie mode. . The speed in the normal mode is not described in detail because it is the same as the conventional one, but in short, the maximum speed is determined by the value of the variable resistor B1, and the actual speed is changed by the operation of the accelerator lever 22. It is determined by the value of B2. On the other hand, the speed in the truck mode is determined as follows. The state of the forward / reverse switch SW2 is read, and it is determined whether the vehicle is traveling backward (steps S3 and S4). If the forward / reverse switch SW2 is set to reverse, the maximum speed VMAX is forcibly set to 2 Km / h irrespective of the variable resistance value B1 (step S5). On the other hand, if the state of the forward / reverse switch SW2 is forward, the maximum speed VMAX is forcibly set to 1 km / h regardless of the value of the variable resistor B1 (step S6). In addition, the fact that the forward / reverse switch SW2 is set to reverse in the truck mode means that the truck is used forward.

Subsequently, the value of the variable resistor B2 that is changed in conjunction with the operation of the accelerator lever 22 is read, and the angle ratio N of the accelerator lever 22 to the maximum angle is obtained (step S7). Then, the set speed VS is obtained by multiplying the angle ratio N by the maximum speed VMAX (step S).
8). Further, the value of the encoder E is read to obtain the actual speed VR (step S9). Then, the set speed VS and the actual speed VR are compared (step S10), and if they are equal, the process returns to step S1 to repeat the above operation.
If not equal, it is further determined whether or not the set speed VS is higher than the actual speed VR (step S11). If the actual speed VR is higher than the set speed VS, the electric motor M is decelerated (step S12). ), Conversely, set speed VS
If it is slower, the speed of the electric motor M is increased (step S
13). Then, returning to step S1, the above operation is repeated. As a result, the electric vehicle 1 travels according to the speed set by the accelerator lever 22.

Next, the operation and effect of this embodiment configured as described above will be described. First, a case where the electric vehicle 1 is used as a bogie will be described. First, lever 1
6A is rotated counterclockwise. Then nut 1
Since the tightening of the lock shaft 16 by 7A, 17B is loosened, the meshing between the two meshing portions 13, 14 is released,
The upper steering shaft 9 can be tilted to the side opposite to the seat 7 side. The tiltable upper steering shaft 9 is tilted toward the front side of the electric vehicle 1, and at a predetermined angular position, the lever 16A is rotated clockwise. Then, loose nuts 17A and 17B
Are fastened, so that the meshing portions 13 and 14 are fixed in the meshing state again. As a result, the upper steering shaft 9 is fixed in a state of being bent to the side opposite to the seat 7 side, so that the steering wheel 12 can be operated from the front of the electric vehicle 1 in a lowered state. further,
If necessary, the seat 7 is removed by withdrawing the seat legs 24 from the leg supports 23. Thereby, the step board 5 can be used as a flat luggage storage.

Here, when carrying the luggage 30 like a truck, the forward / reverse switch SW2 is switched to the reverse side. Then, the maximum speed VMAX is set to 2 km / h. When the accelerator lever 22 is grasped while grasping the handle 12 with both hands, the electric vehicle 1 starts moving rearward (forward when viewed from the worker 31) at a speed corresponding to the angle. Thereafter, the electric vehicle 1 can be moved to the destination by operating the handle 12 while walking. When it is desired to carry the load 30 by pulling it in the direction of the worker 31, the forward / reverse switch SW2 is switched to the forward side. Then, the maximum speed VMAX is set to 1 km / h. Then, for example, if the accelerator lever 22 is gripped while holding the handle 12 with one hand, the electric vehicle 1 starts moving forward (to the rear when viewed from the operator 31) at a speed corresponding to the angle. After that, the electric vehicle 1 may be moved to the destination by operating the handle 12 while pulling.

As described above, in this embodiment, the handle 12
Can be tilted to the side opposite to the seat 7 side, so that the electric vehicle 1 can be steered with the seat 7 lowered.
Therefore, the electric vehicle 1 can be used as a bogie with an electric motor. In addition, the seat 7 is detachably provided on the step board 5, and by removing the seat 7, the luggage can be placed on the step board 5. Therefore, the function as a cart can be further enhanced. In addition, the handle 12
Is tilted to the side opposite to the driver's seat side, this is detected by the steering wheel position detection switch SW1, and the speed of the electric vehicle 1 is suppressed to the walking speed or less. Specifically, when the electric vehicle 1 is used as a bogie while being pushed to the rear, it is 2 Km / h or less. When the electric vehicle 1 is used as a bogie while being moved to be pulled forward, it is 1 Km / h.
m / h or less. Therefore, when the vehicle is used in the trolley mode, the speed of the trolley can be adjusted to the walking speed, so that the steering of the trolley can be simplified and the usability can be improved. When the electric vehicle 1 is used as a trolley while moving forward, the driver walks backward. Therefore, more careful driving is desired. In this case, the maximum speed of the trolley is 1 km / h, which is the slowest. Is more secure.

Next, a description will be given of a case where the electric vehicle 1 is boarded in a normal use mode. During normal operation,
The driver takes a driving posture by sitting on the seat 7 and holding the steering wheel 12. At this time, the power unit 35 of the electric vehicle 1
The battery 40 and the control unit 37 are disposed separately in the front-rear direction of the vehicle. In addition, sheet 6
Are supported by a pair of left and right seat legs 24. By adopting such a structure, a storage space is secured between the seat 6 and the floor, so that more luggage can be carried as compared with a conventional electric vehicle. Further, by disposing the heavy power unit 35, the battery 40, and the control unit 37 in a dispersed manner as described above, the force applied to the floor can be dispersed. Therefore, it is possible to reduce the weight without changing the overall strength as compared with the conventional floor structure. Further, the seat 6 is supported by two seat legs 24. The central one like a conventional electric vehicle
The supporting force of the sheet 6 can be strengthened as compared with the case where the sheet is supported by the book supporting member.

Note that the present invention is not limited to the above embodiment, and for example, the following also belong to the technical scope of the present invention. The arrangement of the power unit, the control unit, and the battery is not limited to the embodiment, and the arrangement may be reversed. Also, by using a thin and lightweight battery (such as a lithium secondary battery),
More luggage storage space can be secured. By using the same height as the battery cover without projecting the insertion portion, when the driver's seat is removed and used in the trolley mode, the transport performance as a trolley can be improved. The maximum speed in the trolley mode is not limited to 2 km / h when traveling backward and 1 km / h when traveling forward, and may be changed as appropriate in accordance with the walking speed. In order to tilt the steering wheel, the upper steering shaft may be rotated in a horizontal plane with respect to the lower steering shaft, instead of tilting the steering shaft back and forth. If the step portion is formed flush with the front and rear, the usability can be further improved when carrying the load. The present invention can be applied not only to a three-wheeled electric vehicle but also to a four-wheeled electric vehicle. Further, the electric vehicle according to the present invention can be widely used as a golf cart or the like without being limited to the use for the elderly and the disabled. In order to make the steering wheel operable from the front, the steering shaft may not necessarily be tilted back and forth, and only the steering wheel may be turned so that the steering can be operated from the front.
