Description

The present invention relates to a portable battery device for retractably storing a battery cartridge.

With the widespread use of mobile terminal devices, it is possible to supply power to mobile terminal devices anytime and anywhere, so that the portability of battery devices is strongly required. Such a portable battery device is also referred to as a mobile battery device or a portable battery device. This type of portable battery device has, for example, a case body, a battery, an insertion plug, a commercial AC voltage input circuit, an AC-DC voltage conversion circuit, a charge control circuit, and a discharge control circuit. (See, for example, Patent Document 1). In general, the battery is often built in the case body and fixed as it is.

By the way, many mobile battery devices are small and lightweight because portability is more important in design than the size of electric capacity. On the other hand, the portable battery device may be designed as an emergency backup power source in the event of a disaster or as a power source for camping or the like, with an emphasis on capacity rather than portability. Therefore, the portable battery device is generally larger and heavier than the mobile battery device. Further, in a portable battery device, due to the large electric capacity, it takes a lot of time to fill the battery when the power is supplied and the battery is recharged.

Therefore, in order to enable immediate power supply, it is considered to provide a cartridge type battery of the portable battery device so that it can be replaced and removed. However, the battery is heavy due to its large electric capacity, and care must be taken in its handling so as not to drop or damage it, and the handling or replacement operation may become complicated.

The side wall portion of the bulging portion is provided with a bulging portion that is provided so as to bulge from the surface on the side that closes the opening toward the accommodating portion and holds the battery inside the bulging portion. A pair of engaging convex portions extending in a rib shape along the insertion / removal direction and arranged facing each other across the main body of the bulging portion are provided, and the side wall portion of the accommodating portion is provided with the pair of engaging portions. A pair of engaging recesses for engaging with the convex portion is extended in a groove shape along the insertion / removal direction, and a tip surface located on the outer peripheral surface of the pair of engaging convex portions on the opposite side of the lid portion. Each is formed in an arc shape as a whole, and each of the bottom surfaces thereof on the inner peripheral surface of the pair of engaging recesses is formed in an arc shape as a whole corresponding to each of the tip surfaces of the pair of engaging protrusions. A portable battery device that is formed.
(2) On the outer peripheral surface of the pair of engaging protrusions, the side wall surfaces other than the tip surface are formed flat, and on the inner peripheral surface of the pair of engaging recesses, the side wall surfaces other than the bottom surface are the pair. The portable battery device according to (1), which is formed in a flat shape corresponding to the side wall surface of the engaging convex portion of the above.
