Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a small electric vehicle used as a wheelchair by elderly people and people with walking disabilities.
The present invention relates to a small electric vehicle that is configured to be able to run using front wheels for steering and rear wheels for driving.

0002

[Prior Art] Conventional small electric vehicles generally cannot be folded compactly, and some are
As shown in Publication No. 27, a front vehicle body equipped with a steering handle and a steering front wheel, and a rear vehicle body equipped with a driver seat, a driving unit, and a driving rear wheel can be slid and fixed in the front and rear directions. There are some configurations that can be configured to make the electric vehicle compact.

0003

[Problem to be Solved by the Invention] According to the above-mentioned conventional structure, it is possible to compactly store an electric vehicle in a garage or the like without taking up space by bringing the front body and the rear body close to each other in the longitudinal direction. However, when loading it into a one-box car and transporting it to a recreational area, the whole thing is too heavy, and in order to load it into a limited space, it is necessary to have the front and rear bodies close together in the longitudinal direction. However, due to its length, it was not possible to load it into a one-box car or the like, and it was not possible to transport it to a recreational area. The present invention enables a small electric vehicle to be transported to a recreational area using a one-box car or the like, and
The purpose is to make this work easier.

0004

[Means for Solving the Problems] A characteristic configuration of the present invention for achieving the above object is that the vehicle body includes a front vehicle body including a steering handle and a steering front wheel, a driver's seat, a driving section, and a rear driving section. The rear vehicle body is divided into two parts in the front and back direction, and each of the divided vehicle bodies is provided with a ground stand that can move in and out.

[0005]

[Operation] Since the car body is divided in the front and rear direction, the front car body and the rear car body can be loaded individually, and loading can be done without requiring much force compared to the conventional car body. Furthermore, since the front body and the rear body can be loaded individually, one large, limited space is not required, and the vehicle can be stored compactly in a small empty space. Further, when the front vehicle body and the rear vehicle body are connected, the ground stand allows the front vehicle body, which tends to fall down, to be maintained in an upright position and connected.

[0006]

[Effects of the Invention] As a result of the above structure, small electric vehicles used by elderly people and people with walking disabilities can be transported to recreational areas using a one-box car or the like. The ground stand also makes it easier to assemble the vehicle body.

[0007]

[Embodiment] Fig. 1 shows a three-wheeled small electric vehicle used as a wheelchair by elderly people and people with walking disabilities. 1 is a control handle, 2 is a driver's seat, and 3 is a battery 3a and an electric motor 3b. 4 is a steering front wheel operated by a steering handle, and 6 is a pair of left and right driving rear wheels driven via the electric motor 3b and differential gear 5. The driving rear wheel 6 can be accelerated by operating a volume (not shown) in a control panel 8 using a handlebar 1a and an accelerator lever 7 that can be grasped.
A speed change switch (not shown) that can switch between high, medium, and low speeds is provided, and the speed can be changed in three stages, and a forward/reverse changeover switch (not shown) allows the vehicle to move forward or backward. The small electric vehicle includes a steering post 1b of the control handle 1, a vehicle body frame that supports the driving unit 3, and the differential gear 5, as well as a cover that integrally covers the front wheels 4, the driving unit 3, and the rear wheels 6. The body 9 includes a foot step part 10, a front body 9A including a steering handle 1 and a steering front wheel 4, and a rear body 9B including a driver's seat 2, a driving unit 3, and a driving rear wheel 6. It is divided into two parts in the front and back direction. As shown in FIG. 3, the front body 9A and the rear body 9B are connected by body frame portions 9a', 9a' protruding from the front body cover 9a, and fitting connections protruding from the rear body cover 9b. The fitting connection member 9b' on the rear body 9B side is configured to be slightly longer than the protruding body frame portions 9a', 9a' on the front body 9A side. This makes it easy to fit and connect. As shown in FIG. 4, ground stands 11a, 11a, 11b, which are rotatable around a horizontal axis, are provided on the rear surfaces of the protruding vehicle body frame portions 9a', 9a' and the fitting connection member 9b', respectively. is provided, and when the vehicle body is separated, it rotates downward by a weak spring (not shown) provided on the pivot shaft. Further, when the vehicle bodies are fitted and connected, when one vehicle body is pushed into the other vehicle body, the two bodies are automatically retracted against the biasing force. Further, as shown in FIG. 1, the control handle 1 is vertically divided into two halves 1A and 1B above the front wheel cover, and the upper handle portion 1A is further removable. Furthermore, the driver's seat 2 and the battery 3a are each removable from the rear vehicle body 9B. As shown in FIGS. 5 and 6, a copper joint 14, a lead wire 15, and a coupler 16 that sandwich the battery terminal 13 are embedded in the battery cover 12, and the coupler 17 on the electric motor side is inserted into the coupler 16. This makes it easier to connect electric wires to the battery.

[Another embodiment] The grounding stand 11a, 1
1a and 11b may be rotated downward by their own weight. Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings by the reference numerals.
