Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a battery housing device for an electric boat toy, and the battery that supplies electricity to the built-in drive motor can be a dry battery or a rechargeable battery. To provide a battery storage device which can selectively store and use battery packs and the like, and which can store these batteries at a low center of gravity so that the electric boat toy itself is stabilized.

(Conventional technology) Batteries used in electric boat toys have traditionally been of the relatively inexpensive dry cell type (including dry cell rechargeable batteries that are relatively expensive but can be expected to rotate the motor at high speed). Rechargeable battery packs are expensive, but they can be expected to rotate at high speeds and are easy to handle. (connected) type.

Most of the battery housing devices formed in electric boat toys are divided into two types: one for dry battery type and the other for battery pack type.

(Problem to be solved by the invention) Therefore, battery packs cannot be used in battery storage devices configured to accommodate dry batteries, and battery packs cannot be used in battery storage devices configured to accommodate battery packs. However, there is a drawback that dry cell type batteries cannot be used, which is very inconvenient, and it is necessary to prepare batteries according to the configuration of the battery storage device.
There were also problems in terms of economics.

Furthermore, since the battery pack is quite heavy, unless it is stored as close to the bottom of the electric boat toy as possible, the stability of the electric boat toy itself will be greatly compromised. That is, in the case of a battery storage device provided in an electric boat toy, consideration must be given so that the battery can be stored at a low center of gravity.

(Means for Solving the Problems) Therefore, the present invention was devised in order to solve the above-mentioned difficulties, etc., and to provide an optimal battery storage device for an electric boat toy. Specifically, the electric boat toy S has a substantially elongated rectangular frame shaped in the front and rear direction consisting of left and right side walls 2, 3, a front wall 4, and a rear wall 5 at the center bottom, and has an open part 1 at the top.
A battery accommodating space 1 is formed. A dry battery supporting slide 10 is mounted in the battery housing space 1 so as to be slidable in the front and rear directions. Then, this slide body 10 for supporting a dry battery is formed to have a length approximately half of the battery housing space 1, and the slide body 10 for supporting a dry battery
When the rear end of the battery storage space 1 is slid toward the rear end of the battery storage space 1, the dry battery support protrusion 6 provided on the front half of the battery storage space 1 and the dry battery support slide 1
It is formed so that the dry battery 30 can be supported by the dry battery support plate 11 of 0. Further, when the dry battery supporting slide 10 is slid toward the front end of the battery storage space 1, a battery pack storage section 8 whose volume increases in the depth direction in the rear half of the battery storage space 1 is formed.
The battery pack accommodating portion 8 is formed so that a rechargeable battery pack 35 can be accommodated therein.

(Function) Therefore, in the battery storage device of the electric boat toy of the present invention, the dry battery supporting slide 10
is capable of sliding in the battery housing space 1 in the front-back direction. Moreover, the dry battery supporting slide body 10
When the rear end of the battery storage space 1 is slid all the way, the battery support plate 11 of the dry battery support slide 10 and the dry battery support protrusion 6 provided on the front half of the battery storage space 1 are used to hold the battery storage space 1 in a predetermined position. Several 30 types of dry cell batteries are supported substantially in series. Further, when the dry battery supporting slide body 10 is slid toward the front end of the battery housing space 1, a battery pack housing section 8 whose volume increases in the depth direction is formed in the rear half of the battery housing space 1. A rechargeable battery pack 35 is set in this battery pack accommodating portion 8.
