[0026] The battery device includes an upper battery cover 41, a battery box 42, and multiple batteries 3. A battery mounting cavity is formed between the upper battery cover 41 and the battery box 42, and the multiple batteries 3 are installed in the battery mounting cavity. An upper positioning key 51 and a lower positioning key 52 are vertically connected to the outer walls of the upper battery cover 41 and the battery box 42, respectively. A keyway 131 for inserting the upper positioning key 51 and the lower positioning key 52 is provided on the inner wall of the heat insulation cylinder 13.

[0027] The locking device includes a handle mechanism and two limiting mechanisms. The handle mechanism includes a sleeve 61, two L-shaped slide rods 62, and two sliding seats 7. The two sliding seats 7 are slidably mounted on both ends of the upper battery cover 41, and the ends of the two L-shaped slide rods 62 are slidably mounted inside the sleeve 61. A first spring 8 is installed inside the sleeve 61, and the other ends of the two L-shaped slide rods 62 are rotatably connected to the sliding seats 7 on both sides. The limiting mechanism includes a sliding frame 16, a first elastic component, a second elastic component, and two positioning pins 10. 16 is connected to the corresponding side sliding seat 7. The upper battery cover 41 has two sliding holes 411 for sliding of the two side sliding brackets 16. The sliding bracket 16 is connected to the upper battery cover 41 through a first elastic component. The first elastic component includes a first guide rod 171, a second spring 172, and a first limiting block 173. The first guide rod 171 movably passes through the sliding bracket 16 and is connected to the inner wall of the upper battery cover 41. The first limiting block 173 is located at the end of the first guide rod 171. The second spring 172 is sleeved and installed on the first guide rod 171. On the guide rod 171, two positioning posts 10 are connected to the sliding brackets 16 on both sides respectively. Both positioning posts 10 movably penetrate the side wall of the upper battery cover 41 and are respectively equipped with the positive terminal 91 and the negative terminal 92 of the battery. Second positioning holes 132 are opened at both ends of the inner wall of the heat insulation cylinder 13. Positive iron plates 14 and negative iron plates 15 are respectively installed on the outer walls of both sides of the heat insulation cylinder 13. The positive iron plates 14 and negative iron plates 15 are electrically connected to the circuit board.

[0028] In this embodiment, when disassembling the battery device, the two L-shaped sliding rods 62 are first squeezed and moved inward to a predetermined position. At this time, the positioning posts 10 on both sides are moved out of the second positioning hole 132, thereby releasing the fixed connection between the battery device and the heat insulation cylinder 13. However, at this time, the end of the L-shaped insert 19 is still inserted into the first positioning hole 421. Then, the battery device is lifted upward to separate it from the heat insulation cylinder 13. After separation, the two sliding seats 7 are pushed closer to each other to a predetermined position. During this process, the sliding frame 16 moves so that the end positioning post 10 moves out of the second positioning hole 132. The sliding frame 16 then moves and contacts the L-shaped insert 19, causing the end of the L-shaped insert 19 to move out of the first positioning hole 421, thereby releasing the fixed connection between the upper battery cover 41 and the battery box 42.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
