Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a small electric vehicle used mainly by physically disabled people and elderly people who have difficulty walking.

[Conventional technology]

Conventionally, this type of small electric vehicle has a dedicated cockpit.

[The problem that the idea aims to solve]

When adopting such a configuration, it is necessary to use this cockpit, so for example, if a person using a general wheelchair (manual) changes to this small electric vehicle, It is necessary to get off the wheelchair and transfer to the small electric vehicle, which is very troublesome. In particular, since the users were physically disabled or elderly, the burden of switching was heavy and sometimes required human assistance.

An object of the present invention is to provide something that can reduce the burden on a person using the wheelchair when switching to the small electric vehicle.

[Means to solve the problem]

The characteristic configuration of the present invention is that a self-propelled aircraft equipped with a control section is provided with a boarding and disembarkation mechanism that allows a wheelchair to be transferred to it, and a fixing mechanism that fixes the wheelchair transferred to the self-propelled aircraft at a position for operating the control section. The parking brake and the getting-on/off mechanism are linked so that the parking brake is activated when the getting-on/off mechanism is in a state that allows transfer.

[Effect]

That is, as shown in FIG. 1, by providing the getting on/off mechanism 11 with a slope-type ramp for transfer, it is possible to transfer to a small electric vehicle while sitting in the wheelchair 10.

The fixing mechanism allows the wheelchair that has been transferred to the small electric vehicle to be fixed in the operating position of the control section, so that the wheelchair can be maintained in a stable posture without moving, and the small electric vehicle can be transferred to the small electric vehicle without having to get off the wheelchair. You will be able to operate the

Furthermore, since the parking brake is activated when the loading/unloading mechanism is in the transfer-permitting state (as in the state where the ramp 11 is open), the wheelchair can be reliably loaded and unloaded while the self-propelled aircraft is stopped. There is no inconvenience caused by forgetting to apply the parking brake and causing the self-propelled aircraft to move unexpectedly when getting on or off the wheelchair.

[Effect of idea]

As a result, it is possible to transfer to and operate a small electric vehicle while riding in a wheelchair, which is particularly useful for people with physical disabilities and the elderly. Moreover, the self-propelled aircraft is automatically stopped when the boarding/disembarking mechanism is activated, making it possible to perform stable and reliable transfer operations.

〔Example〕

As a small electric vehicle, a three-wheeled electric vehicle aimed at people with physical disabilities and the elderly will be explained.

As shown in FIG. 1, a frame is formed by a pipe frame 1a, and a step cover 1b made of integrally molded resin is fixed to this pipe frame 1a to form a vehicle body frame 1. Similarly, a handle support frame made of pipe and sheet metal is fixed to the handle support frame, and a control handle 3 is attached to constitute the control section.A front wheel 7 for single steering is attached to the control handle 3, and a differential mechanism (not shown) is attached to the rear of the body frame 1. A small electric vehicle is constructed by disposing a drive motor 6 for traveling the transmission case 5 and a pair of left and right driving rear wheels 8, 8 which are pivotally supported on the lateral ends of the transmission case 5. Said control handle 3
A pair of left and right batteries 9, 9 are arranged below the cover 1b, and the batteries 9, 9 are positioned and fixed within an annular rib 1c formed on the upper surface of the cover 1b.

A space for transferring the wheelchair 10 is secured in the rear steps 1b of the batteries 9, 9, and a ramp serving as a mechanism 11 for allowing the transfer of the wheelchair 10 is pivoted at the rear end of the vehicle body frame 1 so as to be able to swing up and down. has been done. On the other hand, a fixing mechanism 12 is provided for fixing the wheelchair 10 that has been transferred onto the step at a position for operating the control section. A protruding plate-shaped receiving portion 13 and a fender 14 for rear wheels 8, 8 that receives the rear wheel 10b of the wheelchair 10 from the side surface.
and a ramp 11 that swings and fixes the ramp 11 upward to receive the rear wheel 10b.
Therefore, the wheelchair 10 is fixed in position by these fixing mechanisms 12, and driving operations can be performed while sitting on the wheelchair 10.

As a driving operation mechanism, an operation box 15 is fixedly provided on the operation handle 3, and this operation box 15 has a high-low travel control mechanism that outputs an operation signal to a control circuit (not shown) that controls the drive motor 6. It is equipped with a gear shift lever 16, a forward/reverse switching lever 17, and an accelerator lever 18. This forward/reverse switching lever 17 is operated not only to the forward/reverse operating position but also to the "tapple open" position where the wheelchair 10 can be transferred onto the ramp 11. In other words,
Although the forward/reverse switching lever 17 and the ramp 11 are not shown, they are configured to be linked by a wire linkage mechanism or the like to switch the attitude of the ramp 11 (of course, the attitude of the ramp 11 is switched by an actuator such as a cylinder). ), the parking brake 1 may be activated at this "larp open" position.
This parking brake 19 and the forward/reverse switching lever 17 are linked by a wire (not shown) so that the parking brake 9 is activated.
It has been done. The parking brake 19 may also be configured to serve as a driving brake. Then, the forward/reverse switching lever 17 is in the “larp open” position.
When the position is changed, the power to the drive motor 6 is cut off.

Note that 20 in the figure is a charging terminal provided in a garage or the like.

[Another embodiment] The mechanism 11 for allowing the wheelchair 10 to move on and off may be a platform that moves up and down between the ground and the step 1b, instead of a swinging platform.

The wheelchair 1 serves as the fixing mechanism 12 for the wheelchair 10.
A dedicated fixture for gripping the pipe frame 0 may be provided.

Incidentally, although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.

Claims (1)

[Scope of utility model registration request] A self-propelled aircraft body equipped with a control section is provided with a boarding mechanism 11 that allows the wheelchair 10 to be transferred thereto, and a fixing mechanism 12 is provided that fixes the wheelchair 10 transferred to the self-propelled aircraft at a position for operating the control section. A small electric vehicle in which a parking brake 19 and the getting-on/off mechanism 11 are linked so that the parking brake 19 is operated when the getting-on/off mechanism 11 is in a state allowing transfer.
