[0042] The mounting platform 33 includes a first rod 331 arranged along the third direction Z, a second rod 332 arranged along the first direction X, and a plurality of spacers 333 spaced apart. The first rod 331, the second rod 332 and the spacers 333 are all connected to the corresponding second side plate 313. The first rod 331 and the second rod 332 are perpendicularly connected and form an "L" shape. The second rod 332 is located at the end of the first rod 331 away from the sealing plate 311, and the second rod 332 is located at the end of the first rod 331 away from the first side plate 312. Each spacer 333 protrudes from the end of the second rod 332 away from the sealing plate 311. The second rod 332 and the spacers 333 are all inserted into the corresponding limiting groove 24 to limit the battery cover 30 in the third direction Z.
[0043] The battery cover 30 also includes at least two positioning protrusions 34, each of which protrudes from the two second side plates 313. The locking plate assembly 20 has at least one U-shaped positioning groove 27 on each of the outer side walls along the second direction Y. The axial direction of the positioning groove 27 is along the third direction Z. Each positioning protrusion 34 is respectively inserted into the positioning groove 27 to assist in fixing the battery cover 30 along the first direction X and prevent the battery cover 30 from shaking.
[0044] In some embodiments, there are two positioning protrusions 34, which are respectively disposed on two second side plates 313. The positioning protrusions 34 are semi-cylindrical in shape, and the outer circumference of the positioning protrusions 34 gradually decreases from the end away from the sealing plate 311 to the end closer to the sealing plate 311. There are four positioning grooves 27, which are disposed in pairs on both sides of the U-shaped enclosure 253. Since the battery cover 30 is made of plastic, it has a certain degree of flexibility. When the battery cover 30 is pushed relative to the locking plate assembly 20 in the first direction X for installation, the positioning protrusions 34 will deform the U-shaped enclosure 253. After the battery cover 30 moves into place, the two positioning protrusions 34 are respectively inserted into the two corresponding positioning grooves 27.
