As shown in Figures 1 and 2, the battery case 10 in one embodiment of the application, the battery case 10 include box body 12 and top cover
Plate 14, the lamina tecti 14 are installed in box body 12, to be sealed encapsulation to box body 12.
Box body 12 is fixed including multiple accommodating cavities 122 for putting battery, the circuit board being arranged independently of accommodating cavity 122
Chamber 124, and the first opening 126 being connect with multiple accommodating cavities 122 and circuit board lock chamber 124.Together refering to Fig. 3 and Fig. 4,
Lamina tecti 14 is removably attachable at the first opening 126, and has seal chamber 142,14 outer of lamina tecti inside and seal chamber
It is also formed with the first annular slot 144 being arranged along lamina tecti 14 circumferentially around the seal chamber 142 between 142, the of box body 12
Periphery has the first annular chimb 128 to match with first annular slot 144 at one opening 126.
Specific in embodiment, in a rectangular parallelepiped shape, which is rectangle the box body 12, accordingly, the top
The shape of cover board 14 and the shape of the first opening 126 match, and are arranged at first opening 126.The accommodating cavity 122 includes
Four, four accommodating cavities 122 are arranged into two rows two and arrange, and 124 adjacent four accommodating cavities 122 of circuit board lock chamber are arranged.
The battery case 10 further includes the first encapsulating layer (not shown), the first encapsulating layer be filled in first annular chimb 128 with
Between first annular slot 144.During practical set, battery is placed in corresponding accommodating cavity 122, lamina tecti 14 is aligned
It is caught at the first opening 126, and first annular chimb 128 is made to adapt to first annular slot 144, then formed by encapsulating aforementioned
The first encapsulating layer.
In this way, facilitating the separation and fixation of battery, carrying difficulty and assembly and disassembly when number of batteries increases are effectively reduced
Difficulty improves safety.In addition, first annular slot 144 and first annular chimb 128 is arranged, and first is formed by encapsulating
Encapsulating layer improves the sealing performance of battery case 10, prevents rainwater etc. from entering in battery case 10, and increase lamina tecti 14 and box
The reliability that body 12 connects, further improves the safety and reliability of battery case 10.
It is emphasized that since first annular slot 144 is formed on the inside of 14 outer of lamina tecti between seal chamber 142.
When therefore, at the first opening 126 that lamina tecti 14 is installed in box body 12, first annular chimb 128 adapts to first annular recessed
Slot so that the outer of lamina tecti 14 is wrapped in first annular 128 outside of chimb, and then prevents rainwater from entering, further improves
