Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for driving an electric minicar.

[0002]

2. Description of the Related Art A conventional driving method of an electric minicar has been performed only by a driving device of the electric minicar in the same manner as a normal automobile.

[0003]

In the conventional electric minicar, it is impossible to drive in an electric wheelchair, and in the case of parking or the like, an elderly person or a woman must turn the steering wheel, which is the weakest point of operation. There was a problem that it did not become.

According to the present invention, an electric mini-car can be driven in an electric wheelchair, and a driving device of the electric wheelchair can be used if necessary. It is an object of the present invention to provide an electric minicar that can be easily operated.

[0005]

In order to achieve the above object, in the electric minicar of the present invention, an electric wheelchair lift that moves up and down symmetrically to the left and right is mounted on the electric minicar, and the electric wheelchair moves right and left on the wheel bearing portion of the lift. A means for fitting and fixing the axle of an electric wheelchair (for example, see Japanese Patent Application Laid-Open No. H10-500049) rotating on the spot was taken.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. In FIG. 1, an elevating lift 2 with a uniting / separating device is mounted on the inner surface of the center of the side surface of the body 1 of the electric minicar. The lift frame 6 provided and a cylinder 8 of an actuator 7 for moving the lift frame 6 up and down are fixed. Also, lift frame 6
The shaft 9 and the actuator 7 are fixed to the body 1 of the electric minicar. The shaft 9 and the lift frame 6 are mounted so as to be moved via a bush 10 fixed to the lift frame 6.

Although only the body side of the electric minicar has been described above, the structure of the door side is the same. In addition,
The upper and lower positions of the wheel bearing 6 are adjusted to make the same movement. The front and rear dimensions of the wheel bearing 6 are, of course, set to the same dimensions as the axle dimensions of the electric wheelchair 3.

In the embodiment shown in FIG. 2, the lift 2 is in an intermediate position with the door 11 of the electric minicar closed and the electric wheelchair 3 fixed to the electric minicar.

FIG. 3 shows an embodiment in which the electric wheelchair 3 is combined (or separated) into an electric minicar.
The axle 4 and the wheel bearing 5 of the lift 2 have been fitted, and the door 11 of the electric minicar is in a half-open state. Of course, if one side surface is completely fitted, the door side is also set to close securely.

The embodiment shown in FIG. 4 shows a case where the lift 2 is at the uppermost position, that is, the electric wheelchair 3 is at the uppermost position, and the vehicle is running using a driving device (not shown) of the electric minicar. Show.

The embodiment shown in FIG. 5 shows a state in which the lift 2 is at the lowermost position, that is, the electric wheelchair 3 is at the lowermost position, and the electric wheelchair is driven using the driving device.

[0012]

Since the present invention is configured as described above, the following effects can be obtained.

[0013] The use of the electric minicar drive device facilitates the mid-range movement, which is a drawback of the electric wheelchair.

[0014] Further, by using the driving device of the electric wheelchair which moves sideways and rotates on the spot, "switching handle operation" which is necessary for parking etc. which is a drawback of the conventional electric minicar is unnecessary. , And driving becomes easier.

[0015] That is, an ideal car that combines the features of an electric minicar and an electric wheelchair that moves sideways and rotates on the spot,
It is possible to provide an unprecedented vehicle such that the user of the electric wheelchair can drive without an attendant and, of course, can use the electric wheelchair alone.
