DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small-sized electric vehicle used by elderly people and people who have difficulty walking.

[0002]

2. Description of the Related Art Conventionally, in a small electric vehicle, when a vehicle is loaded and transported on another vehicle, the vehicle body is directly loaded on a vehicle carrier and transported.

[0003]

However, although this kind of small electric vehicle is small in size as compared with a general passenger car, it is small in weight, but when it is carried on a vehicle, it is difficult to carry it. The work load was heavy.
The present invention focuses on this point, and makes it possible to reduce the work load during transportation by making the shape as compact as possible when carrying during transportation, and to facilitate the handling. Aim.

[0004]

In order to achieve the above object, the present invention is characterized in that a vehicle body is configured to be separable into a front vehicle body and a rear vehicle body, and the front vehicle body is capable of moving back and forth. A grounding stand is provided, and the grounding stand is linked with a lock mechanism that connects a front vehicle body and a rear vehicle body. The ground stand is brought into an operating posture by unlocking the lock mechanism, and the locking operation is performed by the lock operation. The point is that the grounding stand is configured to be switchable to the non-operating posture.

[0005]

[Function] When the body is transported, the vehicle body is separated back and forth to reduce the weight burden during the loading operation. When the front vehicle body and the rear vehicle body are separated from each other, when the lock mechanism is unlocked, the ground stand of the front vehicle body is switched to the operating posture, so that the unstable front vehicle body is prevented from tipping over.

[0006]

Therefore, the rational improvement enables the body to be made compact during transportation, and the loading operation can be performed easily. In addition, when the vehicle body is separated, the grounding stand of the front vehicle body is switched to the operating posture, so that the unstable front vehicle body is prevented from tipping over, and loading into the vehicle becomes easy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to a small electric vehicle used by elderly people and people with mobility difficulties for transportation. FIG. 2 shows a small electric vehicle. This electric vehicle includes a pair of left and right rear wheels 2 and 2 that are driven by an electric motor 1 through a differential device (not shown) in a traveling transmission case M. The vehicle has a single front wheel 3 that can be steerably operated. A driver's seat 4 is provided above an intermediate portion between the left and right rear wheels 2, 2, and a steering section 6 is provided at an upper end of a steering shaft 5 of the front wheel 3. The steering unit 6 is provided with a left and right steering handle 7, the potentiometer-type speed setting lever 8 is operated together with the steering handle 7 to drive and control the electric motor 1, and the speed setting lever 8 is released. An electromagnetic brake (not shown) interposed in the traveling drive system is operated to stop the aircraft.

[0008] The electric vehicle has a structure that can be divided into two front and rear parts. More specifically, as shown in FIG. 3, a front body frame 11 extends from the front wheel support 9 to a support vertical frame 10 forming portion of the driver's seat 4, and the front wheel 3 is mounted on the front body frame 11. The front vehicle body A is configured by placing and supporting the front cover 12 which also serves as a cover and a driving unit step. A rear cover 17 is provided above a rear transmission frame 16 that supports the traveling transmission case M that supports the left and right rear wheels 2, 2, the battery 13, the charger 14, the control box 15, and the like. The fuselage B is configured.

As shown in FIG. 4, the front body frame 11
At the rear end, there is provided a horizontal frame portion 18 in the shape of a square pipe extending over substantially the entire width of the fuselage. is there. At the front end of the rear body frame 16, a round pipe-shaped connecting tool 20 is provided at the center in the left and right direction toward the front of the body, and the left and right sides are in contact with the lower surface of the horizontal frame section 18 in a connected state. The plate-shaped contact support portions 21 and 21 are formed. When connecting the front and rear vehicle bodies, a round pipe-shaped connecting member 20 is inserted into the rectangular tubular portion 19, and a lock pin 22 as a lock mechanism is inserted into the both 19, 20 to prevent the two 19, 20 from coming off. And the lock pin 22
The retaining pin 23 is inserted to prevent the lock pin 22 from being removed. When the connecting member 20 is inserted and prevented from coming off, the connecting member 20 can be slightly rotated relatively around the longitudinal axis. The contact supporting portions 21 and 21 contact the lower surface of the horizontal frame portion 18. To prevent relative rotation.

On the lower surface of the horizontal frame portion 18 at the rear end of the front body frame 11, a pair of left and right ground stands 24, 24 that can swing around the horizontal axis P, are provided. On the support shaft 24a of the ground stands 24, 24,
When the lock pin 22 is inserted, a contact member 25 is provided as a linking mechanism that can be contacted, and the ground stand 24 is constantly urged by a spring 26 to the stand action posture side, and The pair of left and right ground stands 24, 24 can be switched to the operating position by unlocking the lock pin 22, and the pair of left and right ground stands 24, 24 can be switched to the non-operating position by the locking operation. . As shown in FIG. 5, a charging cord reel 27 is attached to the inner surface of the rear cover 17 via brackets 28, 28 integrated with the rear cover 17, and can be pulled out from the outside.

As shown in FIG. 3, the steering shaft 5 is configured to be able to bend around a horizontal axis X in the middle of the vertical direction.
5b, the upper and lower shafts 5a, 5b are positioned on the same axis and set in a steering mode. When this tubular member 29 is slid upward, the shafts 5a, 5b It is made to be able to rotate relatively around. Driver seat 4
Is detachably mounted on the upper part of the vertical frame 10 so that it can be removed during transportation.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the accompanying drawings.
