Description

DETAILED DESCRIPTION OF THE INVENTION The present invention stores a large number of batteries in a charged state, which are mounted on four batteries, as a power source for the travel drive motor in the luggage transportation truck, as well as for various control circuits and drive machines to be controlled. When a cart arrives at a battery exchange station with a low amount of electricity remaining in its four-mounted battery, the battery that is about to finish discharging can be efficiently replaced with a charged battery without having to wait for a while. More specifically, a battery storage shelf equipped with a mounting storage part for a battery or a battery case and a charger is arranged on one vertical axis that can be driven and rotated at appropriate intervals in the direction of the vertical axis. The present invention relates to a charging storage device for a battery for a luggage carrier that is fixed.

In conventional battery charging and storage devices, each of the battery storage shelves is made up of a single component, which is extremely heavy and difficult to handle, making it difficult to manufacture and assemble. The drawback was that it required a lot of time and effort. In particular, in order to increase the number of batteries stored in the device as a whole, increasing the number of batteries stored in the battery storage shelves and the number of battery storage shelves installed can be avoided by increasing the weight of the battery storage shelves, rather than increasing the number of batteries stored in the device as a whole. Due to the increased bulk, the aforementioned manufacturing and assembly aggravates the above disadvantages.

An object of the present invention is to improve the above-mentioned drawbacks by rationally modifying the battery storage shelf.

The characteristic configuration of the battery charging and storage device according to the present invention, which has been made to achieve such an object, is that each of the battery storage shelves is arranged in a plurality of pieces in the rotational direction with each of the battery storage shelves passing through or near the vertical axis. The structure is divided into two parts, and each of these divided shelf parts is configured to be fixedly connectable.

Finally, by constructing each of the battery storage shelves described above from a plurality of divided shelves that can be fixedly connected, although the number of parts increases as a whole, the weight of each part is light, and processing and assembly are time-consuming. In addition, since each divided shelf passes through or near the vertical axis, each divided shelf can be easily handled not only vertically but also horizontally with respect to the vertical axis. The degree of freedom in assembling has increased as it can be installed even from the inside, and overall the manufacturing and assembling work has become efficient and easy.

Embodiments of the present invention will be described below based on the drawings.
