[0032] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] See also Figure 1 and Figure 2The battery cabin 100 includes a cabin body 1, a top cover 2, a first connecting piece 3 and a second connecting piece 4. The cabin body 1 is provided with a mounting groove 11, and the mounting groove 11 is used to accommodate the battery 200. The top cover 2 is detachably connected to the cabin body 1, and the top cover 2 is used to cover the mounting groove 11. When the battery 200 is installed in the mounting groove 11, the top cover 2 can provide protection for the battery 200. The first connecting piece 3 and the second connecting piece 4 are both fixed to the cabin body 1, and at least a portion of the first connecting piece 3 is accommodated in the mounting groove 11, and the portion of the first connecting piece 3 accommodated in the mounting groove 11 is used to connect the positive electrode of the battery 200, and at least a portion of the second connecting piece 4 is accommodated in the mounting groove 11, and the portion of the second connecting piece 4 accommodated in the mounting groove 11 is used to connect the negative electrode of the battery 200. The first connecting piece 3 and the second connecting piece 4 can also be connected to a load (not shown) so that the battery 200 can supply power to the load. In the prior art, since the top cover 2 is not provided, the battery 200 is too exposed to the outside world, so that external pollutants are easy to fall on the battery 200. When some conductive metals or metal shavings fall on the battery 200, it is easy to cause a short circuit in the battery 200, or when some chemical substances fall on the battery 200, it is easy to corrode the battery 200. Therefore, excessive exposure of the battery 200 to the outside world will affect the safety of the battery 200. Therefore, in this embodiment, the top cover 2 is detachably connected to the cabin body 1, and the top cover 2 covers the mounting groove 11, which can reduce the pollutants falling on the battery 200, which is conducive to improving the safety of the battery 200. In addition, it can reduce the risk of human body touching the battery 200, thereby reducing the occurrence of accidents.

[0034] In this embodiment, the first connecting plate 3 is used to connect the positive electrode of the battery 200, and the second connecting plate 4 is used to connect the negative electrode of the battery 200. It can be understood that in some embodiments, the first connecting plate 3 can be connected to the negative electrode of the battery 200, and the second connecting plate 4 is connected to the positive electrode of the battery 200.

[0035] In some embodiments, see Figure 3 The cabin body 1 is provided with a first snap-fitting portion 12, and the top cover 2 is provided with a first snap-fitting portion 21. When the first snap-fitting portion 21 is snap-fitted to the first snap-fitting portion 12, the top cover 2 is fixed to the cabin body 1. When the first snap-fitting portion 21 is separated from the first snap-fitting portion 12, the top cover 2 can be detached from the cabin body 1. In this embodiment, the top cover 2 and the cabin body 1 are fixed by snapping the first snap-fitting portion 12, and the operation is simple.

[0036] It is understandable that the top cover 2 and the cabin body 1 can also be fixed by screws, which will not be described in detail here.

[0037] In some embodiments, the top cover 2 can rotate relative to the cabin body 1. Figure 3 and Figure 4, Figure 3 2 is a schematic diagram of the structure of the battery cabin 100 when the top cover 2 is in the first preset position. When the top cover 2 is in the first preset position relative to the cabin body 1, the first buckle 21 and the first engaging portion 12 are separated. At this time, the top cover 2 can be detached from the cabin body 1; please refer to Figure 5 and Figure 6 , Figure 5 It is a structural schematic diagram of the battery cabin 100 when the top cover 2 is in the second preset position. When the top cover 2 rotates to the second preset position relative to the cabin body 1, the first buckle 21 is engaged with the first engaging portion 12. At this time, the top cover 2 is fixed to the cabin body 1.

[0038] In some embodiments, see Figure 7 The top cover 2 includes a cover body 22 and a first connection portion 23. One end of the first connection portion 23 is connected to a first surface 221 of the cover body 22. The first connection portion 23 is located at the edge of the first surface 221. Figure 2 and Figure 7 The first buckle 21 is disposed on the first connecting portion 23. Along the first direction X, the first buckle 21 is opposite to the first surface 221, wherein the first surface 221 faces the mounting groove 11. Figure 3 and Figure 6 The first engaging portion 12 includes a first flat section 122, a first transition section 123 and a first engaging section 124. The first transition section 123 is configured as a slope structure. The two ends of the first transition section 123 are respectively connected to the first flat section 122 and the first engaging section 124. In the process of the top cover 2 rotating from the first preset position to the second preset position, the first buckle 21 slides over the surface of the first flat section 122 away from the cover body 22 and the surface of the first transition section 123 away from the cover body 22 in sequence, and then is engaged with the first engaging section 124. When the top cover 2 is in the second preset position, the first buckle 21 is engaged with the first engaging section 124. At this time, the top cover 2 is fixed to the cabin body 1.

[0039] In some embodiments, the first connecting portion 23 and the first buckle 21 are elastic, so that when the top cover 2 is rotated to the second preset position, the first connecting portion 23 and the first buckle 21 can be elastically deformed so that the first buckle 21 can remain engaged with the first engaging section 124. When the top cover 2 is rotated to the first preset position, the first connecting portion 23 and the first buckle 21 can be restored to a free state.

[0040] In some embodiments, see Figure 4 The first buckle 21 is provided with a first protrusion 211 and a second protrusion 212 on one side facing the first surface 221. The first protrusion 211 and the second protrusion 212 are spaced apart so that a first slot 213 is formed between the first protrusion 211 and the second protrusion 212. Figure 3and Figure 6 , a first locking protrusion 121 is provided on a side of the first locking portion 12 away from the first surface 221. When the top cover 2 is in the second preset position relative to the cabin body 1, at least a portion of the first locking protrusion 121 is locked in the first locking groove 213, so that the first protrusion 211 and the second protrusion 212 can jointly limit the rotation of the top cover 2 relative to the cabin body 1, thereby achieving the fixation between the top cover 2 and the cabin body 1. In this embodiment, by forming the first locking groove 213 between the first protrusion 211 and the second protrusion 212, when the first locking protrusion 121 is locked in the first locking groove 213, the first protrusion 211 and the second protrusion 212 jointly limit the rotation of the top cover 2 relative to the cabin body 1, thereby reducing the risk of the top cover 2 being separated from the cabin body 1 without external force intervention, and improving the stability of the fixation between the top cover 2 and the cabin body 1.

[0041] Furthermore, the first locking protrusion 121 is disposed on a side of the first locking section 124 facing away from the cover body 22 .

[0042] In some embodiments, see Figure 3 and Figure 4 The first protrusion 211 is provided with a first guiding inclined surface 2111, and the first guiding inclined surface 2111 is located at a side of the first protrusion 211 away from the second protrusion 212, so that when the top cover 2 rotates from the first preset position to the second preset position, the first latching protrusion 121 can pass through the first protrusion 211 from the first guiding inclined surface 2111 and then be latched into the first latching groove 213, thereby achieving the fixation between the top cover 2 and the cabin body 1. In this embodiment, by providing the first guiding inclined surface 2111, the first latching protrusion 121 can slide along the first guiding inclined surface 2111 and pass through the first protrusion 211 and then enter the first latching groove 213, which is conducive to reducing the force required to latch the first latching protrusion 121 into the first latching groove 213, thereby reducing the difficulty of latching the first latching protrusion 121 into the first latching groove 213.

[0043] In some embodiments, see Figure 3 and Figure 4 A second guiding slope 2112 is provided on one side of the first protrusion 211 facing the second protrusion 212, and the second guiding slope 2112 and the first guiding slope 2111 are respectively provided on two opposite sides of the first protrusion 211. In the process of detaching the top cover 2 from the cabin body 1, the top cover 2 needs to be rotated from the second preset position to the first preset position. By providing the second guiding slope 2112, the first clamping protrusion 121 can leave the first clamping groove 213 along the second guiding slope 2112, thereby reducing the difficulty of detaching the top cover 2.

[0044] In some embodiments, see Figure 2 and Figure 8The cabin body 1 is provided with a second snap-fitting portion 13, and the second snap-fitting portion 13 and the first snap-fitting portion 12 are spaced apart along the outer wall 17 of the cabin body 1. The top cover 2 is provided with a second snap-fitting portion 25, and the second snap-fitting portion 25 and the first snap-fitting portion 21 are spaced apart. Figure 8 , Figure 8 The structure of the battery cabin 100 is shown when the top cover 2 is in the first preset position. When the top cover 2 is in the first preset position, the second buckle 25 and the second engaging portion 13 are in a separated state, and the first buckle 21 and the first engaging portion 12 are also in a separated state. At this time, the top cover 2 can be removed from the cabin body 1; see Fig.10 , Fig.10 The structure of the battery cabin 100 is shown when the top cover 2 is in the second preset position. When the top cover 2 is rotated to the second preset position, the second snap 25 is snapped with the second snap part 13, and the first snap 21 is also snapped with the first snap part 12, so as to achieve the fixation between the top cover 2 and the cabin body 1. In this embodiment, by providing the second snap part 13 on the cabin body 1 and the second snap 25 on the top cover 2, the fixation between the top cover 2 and the cabin body 1 is achieved through the snap-fitting between the first snap 21 and the first snap part 12 and between the second snap 25 and the second snap part 13, which is conducive to improving the stability of the fixation between the top cover 2 and the cabin body 1.

[0045] In some embodiments, see Figure 7 The top cover 2 includes a second connecting portion 24, a second buckle 25 is disposed on the second connecting portion 24, and along the first direction X, the second buckle 25 is opposite to the first surface 221. A third protrusion 251 and a fourth protrusion 252 are disposed on the side of the second buckle 25 away from the first surface 221, and the third protrusion 251 and the fourth protrusion 252 are spaced apart so that a second slot 253 is formed between the third protrusion 251 and the fourth protrusion 252. Please refer to Figure 8 The second engaging portion 13 includes a second flat section 132, a second transition section 133 and a second engaging section 134. The two ends of the second transition section 133 are respectively connected to the second flat section 132 and the second engaging section 134. The second engaging section 134 is provided with a second engaging protrusion 131 on the side away from the cover body 22. Figures 8 to 11 ,in, Figure 8 shows a schematic structural diagram of the battery cabin 100 when the top cover 2 is in the first preset position, Fig. 9The schematic diagram of the structure of the battery cabin 100 when the top cover 2 is in the second preset position is shown. When the top cover 2 rotates from the first preset position to the second preset position, the second latching protrusion 131 slides along the surface of the third protrusion 251 away from the cover body 22 and is snapped into the second latching groove 253, wherein, when the top cover 2 is in the second preset position, the second latching protrusion 131 is snapped into the second latching groove 253. In this embodiment, by arranging the second latching protrusion 131 on the second snapping section 134, a second snapping groove 253 is formed between the third protrusion 251 and the fourth protrusion 252, and by snapping the second latching protrusion 131 into the second snapping groove 253, the stability of the fixation between the top cover 2 and the cabin body 1 can be improved, and the risk of the second buckle 25 being separated from the second snapping section 134 without external force intervention can be reduced.

[0046] In some embodiments, see Figure 2 The side wall of the top cover 2 is provided with a striped structure 222, which is used for the user to grasp. When the top cover 2 needs to be rotated from the first preset position to the second preset position, or from the second preset position to the first preset position, the user can grasp the striped structure 222. The striped structure 222 can increase the friction between the user's fingers and the top cover 2, thereby reducing the difficulty of rotating the top cover 2.

[0047] In some embodiments, see Figure 2 A cross groove 223 is provided on the surface of the cover plate body 22 facing away from the cabin body 1 , so that a screwdriver can be used to screw the top cover 2 through the cross groove 223 to rotate the top cover 2 relative to the cabin body 1 .
