The headrest 45 is located near the back of the head of a person sitting on the wheelchair 70 when the wheelchair 70 is placed on the platform 27.

A pair of right and left ribs 47 extending forward from the lower end of the rear frame 38 is provided on the upper surface of the floor plate 37.
1 is allowed to enter. Further, a pair of left and right lock mechanisms 49, which will be described later, are provided at the inner rear positions of the ribs 47 so that the wheelchair 70 can be fixed at a predetermined lock position. Also,
The right side frame 39 is provided with a release lever 51 for releasing the lock, and is connected to the lock mechanism 49 by a wire 52.

The platform 27 is located on the floor panel 14 and has a wheelchair 70 in a driver's seat position (see FIGS. 1 and 2). Is moved to / from the getting on / off position (see FIG. 3) for getting on / off. Platform 2
The seven floor plates 37 are provided with four positioning projections 53 projecting downward, and can be fitted into the positioning holes 15 provided in the floor panel 14 at the operation position.

The lock mechanism 49 is, as shown in FIG.
A pair of flat base portions 54 facing each other are provided in parallel with each other, and a pair of upper and lower guide portions 55 project from front ends of both base portions 54. (In order to show the internal mechanism, the base 54 on the near side is not shown.) A receiving portion 56 is recessed between the guide portions 55, and the receiving portion 56 has a wheelchair 70. A lock bar 73 provided in the left-right direction in the frame 72 can enter.
A locking piece 58 having a hook 58A and a locking recess 58B is rotatably attached to the base end of the lower guide portion 55 via a pin 59 between the base portions 54. Can be engaged with the lock bar 73 that has entered the interior of the receiving portion 56. A locking piece 61 and a releasing operation piece 62 are attached to the base end of the upper guide section 55 via a pin 63 so as to be rotatable and integrally linked. The locking piece 61 is provided with a chevron-shaped locking claw 61A.
Hook 58A is engaged with the receiving portion 56.
It is in a state of protruding inside. The release operation piece 62 extends rearward, and a wire 52 is connected to a rear end thereof.
When the wire 52 is pulled by the operation of the release lever 51, the wire 52 rotates together with the locking piece 61. The release operation piece 62 and the lock piece 58 are connected to a spring 64.
When the wire 52 is pulled and the release operation piece 62 rotates, the lock piece 58 is connected to the hook 58A.
Is turned in the opening direction.

The present embodiment has the above configuration, and its operation will be described below. In order for the driver in the wheelchair 70 to get into the electric vehicle 10, the driver first operates the remote controller to operate the platform 2 in the driving position.
7 is moved to the getting on / off position. Specifically, when the remote controller is operated, first, the elevating motor 32 is driven to rotate the male screw body 31. Then, along with this, the bracket 26 is raised, the platform 27 is lifted from the floor panel 14, and each positioning projection 53 is separated from the positioning hole 15 (see FIG. 5). When the platform 27 is lifted to a predetermined height position,
The lift motor 32 stops under the control of the CPU, and the rotation motor 35 is driven. Then, the platform 27
Pivots horizontally about the pivot shaft 33 to the left side of the vehicle body, and when it pivots 90 degrees, the rotation motor 35 stops (the state shown in FIGS. 4 and 7). Then, the elevating motor 32 is driven again, and the male screw body 31 rotates in the opposite direction to the above. Then, the platform 27 descends, and when it reaches the ground, the elevating motor 32 stops.

After the platform 27 is set at the getting on / off position in this way, as shown in FIG.
Facing the platform 27,
Ride on 7. At this time, a step may be formed between the floor plate 37 of the platform 27 and the ground. However, when the wheelchair 70 is stepped backward, it is possible to get over the step more easily than when stepping forward.

Subsequently, the wheelchair 70 is moved to the platform 2
7 is moved to the rear side of the lock bar 7 of the wheelchair 70.
3 enters the receiving portions 56 of the left and right lock mechanisms 49 and strikes the hooks 58A. Then, the hook 58A is pushed down, and the locking claw 61A is separated from the locking recess 58B. When the lock bar 73 reaches the inside of the receiving portion 56, the locking claw 61A is engaged with the locking concave portion 58B by the bias of the spring 64, and the hook 58A protrudes into the receiving portion 56, and the lock bar 73 is engaged with the locking bar 73. Engage. Thus, the wheelchair 70 is fixed at the locked position with respect to the platform 27. In this locked position, the headrest 45 is located at the back of the head of the driver sitting on the wheelchair 70.

Next, the remote controller is operated again to return the platform 27 from the getting on / off position to the operating position. Then, the platform 27 rises in a direction opposite to the above to a predetermined height position, rotates forward, and further descends onto the floor panel 14. As a result, the positioning projections 53 of the floor plate 37 of the platform 27 are fitted into the positioning holes 15 of the floor panel 14 (see FIG. 6), and the platform 27 is positioned at the driving position, and the wheelchair 70 is at the driving seat position. Will be installed. During the operation of the platform 27, the driver can make the headrest 45 always support the head.

In this way, the driver can get on and drive the electric vehicle 10 alone while sitting in the wheelchair 70. The headrest 45 can be used as it is during driving. When getting off the vehicle, the user operates the remote controller as described above to move the platform 27 to the getting on / off position. And release lever 5
When the pusher 1 is pushed forward, the wire 52 is pulled, the release operation piece 62 rotates upward, the lock piece 58 rotates via the spring 64, the hook 58A falls, and the engagement with the lock bar 73 is established. It is released. Therefore, wheelchair 70
If you move forward, you can descend to the ground.

According to the present embodiment as described above,
When the driver sitting in the wheelchair 70 gets on and off the electric vehicle 10, the driver is lifted to a high place by the lift device 24,
In some cases, a slight vibration or the like may be felt.
Since the head can be supported by the headrest 45 during the operation, the feeling of anxiety is reduced. Platform 27
Is installed as a seat together with the wheelchair 70, so that the headrest 4
5 can be used.

The technical scope of the present invention is not limited by the above-described embodiment. For example, the followings are also included in the technical scope of the present invention. (1) In the above-described embodiment, an example in which the present invention is applied to a single-seat electric vehicle 10 has been described. However, the present invention is also applied to other types of vehicles, for example, a vehicle with two or more passengers or a gasoline vehicle. be able to. (2) In the above embodiment, the platform 27 is fixed as a seat at the driver's seat position together with the wheelchair 70. However, according to the present invention, the platform on which the wheelchair is mounted is not at the driver's seat position but at another position. The wheelchair may be fixed, and the wheelchair may be lowered from the platform after the wheelchair is placed in the vehicle.Furthermore, if a person sitting in a wheelchair without using the wheelchair as a seat, You may transfer from a wheelchair to another seat.

(3) In the above embodiment, the lift device 24
Is integrally provided with the electric vehicle 10, but according to the present invention, the lift device may be separate from the vehicle body. Further, the lift device may be used not only for wheelchairs but also for loading and unloading luggage. (4) In the lift device 24 of the above embodiment, the platform 27 that can be driven by the wheelchair 70 is provided as a holding portion. According to the present invention, for example, an arm or the like is provided at the lower portion of the wheelchair as the holding portion of the lift device. It may be something like inserting and lifting.
