Abstract

This application relates to an aviation battery, including a casing and an energy storage unit, a support plate, and an electrical unit disposed within the casing. The bottom wall of the casing has spaced-apart limiting strips, and between adjacent limiting strips are spaced-apart height limiting strips with a height lower than the limiting strips. The energy storage unit is placed on the height limiting strips and abuts against two adjacent limiting strips in the length or width direction of the casing. Each limiting strip has an overflow space, which communicates with the gap formed between two adjacent height limiting strips. The support plate supports the electrical unit above the energy storage unit, and the support plate and the energy storage unit are jointly fixed to the bottom wall of the casing by fasteners. This design ensures that the adhesive is evenly spread and excess adhesive is drained during the coating process, meeting the uniformity and controllability requirements of aviation-grade adhesive coating. Simultaneously, the double-layer structure improves spatial integration, reduces the number of fasteners, enhances overall structural stability, and solves the problem of difficult component assembly in confined spaces.
