Annular battery pack bin

Abstract

The invention provides an annular battery pack bin which comprises a cylindrical battery bin body. a through column core hole is formed in the center, multiple longitudinal grooves are formed in the outer wall, an inner-layer battery bin and an outer-layer battery bin which are communicated to the bottom are formed in the top surface of the battery bin body, the bottom of the battery bin body is further surrounded with an outer pad layer, a middle pad layer and an inner pad layer, the outer pad layer covers a part of the inner-layer battery bin, the middle pad layer is arranged between the inner-layer battery bin and the outer-layer battery bin in a surrounding mode, and the inner pad layer is arranged between the inner-layer battery bin and the column core hole. The annular battery pack bin is a circular-ring-shaped double-layer battery bin, utilizes the space to the most degree, can resist severe shake of a beacon light, can simultaneously contain multiple batteries, each battery is provided with a partition part for preventing accidental short circuit, the pad layers and metal sheets are arranged at the bottom, a supporting effect is played on the batteries in the battery bin, and meanwhile the batteries can be also communicated by using the metal conductor sheets.

Description

technical field [0001] The invention relates to the field of batteries for navigation lights, in particular to an annular battery pack compartment. Background technique [0002] The navigation light is a night luminous sign set on the shore or on the water to ensure the safe navigation of the ship at night. The lithium-ion battery is a new generation of rechargeable battery developed after the MH-Ni battery. Because of its high working voltage, high energy density, and safety The advantages of good performance, light weight, small self-discharge, long cycle life, no memory effect, and no pollution have become the key research areas of new energy development. Therefore, the energy supply used in most navigation lights uses solar energy combined with lithium-ion batteries. form. Existing lithium-ion batteries are generally combined in series and parallel to form a block-shaped battery pack, while the lamp body of the beacon light is mostly cylindrical, and the block-shaped ba...

AI Technical Summary

Problems solved by technology

Existing lithium-ion batteries are generally combined in series and parallel to form a block-shaped battery pack, while the lamp body of the beacon light is mostly cylindrical, and the block-shaped battery pack cannot fit in the space of the cylindrical beacon light body. Placement, the space of the cylindrical lamp body cannot be utilized to the greatest extent

In addition, when the navigation light is installed on the buoy, it is often shaken violently, and the batteries connected in series and parallel in the existing battery pack are prone to line failure
