The first housing portion 110a and the second housing portion 110b overlap each other, and the first housing portion 110a and the second housing portion 110b together define a storage space for accommodating the battery cells 120. The second housing portion 110b may be a hollow structure with one end open. The first housing portion 110a is a plate-like structure, and the first housing portion 110a overlaps the open side of the second housing portion 110b to form the housing 110 with the storage space. The first housing portion 110a and the second housing portion 110b may also each be a hollow structure with one end open. The open side of the first housing portion 110a overlaps the open side of the second housing portion 110b to form the housing 110 with the storage space. Of course, the first housing portion 110a and the second housing portion 110b may have various shapes, such as a cylinder, a rectangular parallelepiped, etc.

[0055] Assuming that the first box portion 110 a covers the top of the second box portion 110 b , the first box portion 110 a can also be referred to as an upper box cover, and the second box portion 110 b can also be referred to as a lower box.

[0056] In the battery 100 , there can be one or more battery cells 120 . If there are multiple battery cells 120 , the multiple battery cells 120 can be connected in series, in parallel, or in a mixed connection. Mixed connection means that the multiple battery cells 120 are connected in both series and parallel.

[0057] Multiple battery cells 120 can be directly connected in series, in parallel, or mixed together, and then the whole formed by the multiple battery cells 120 can be accommodated in the box 110; of course, multiple battery cells 120 can also be first connected in series, in parallel, or mixed together to form a battery module, and then the multiple battery modules can be connected in series, in parallel, or mixed together to form a whole and accommodated in the box 110.

[0099] When the limiting beam 211b is rotationally connected to the connecting beam 211a, the driving assembly 30 further includes a driving motor connected to the limiting beam 211b and capable of driving the limiting beam 211b to rotate relative to the connecting beam 211a.

[0100] The extending direction of the rotation axis of the rotational connection between the limiting beam 211 b and the connecting beam 211 a may be along the first direction X. The driving assembly 30 may be connected to the support member 10 .

[0101] The cache device 400 provided in the embodiment of the present application can adjust the volume of the cache space 22 by driving the limiting beam 211b to rotate relative to the connecting beam 211a through a driving motor by rotatably connecting the limiting beam 211b to the connecting beam 211a.

[0102] The buffer device 400 provided in the embodiment of the present application utilizes a limiting beam 211b rotatably connected to the connecting beam 211a, and a corresponding drive motor is provided to drive the limiting beam 211b. The size of the buffer space 22 can be adjusted by adjusting the angle of the limiting beam 211b relative to the connecting beam 211a, thereby facilitating the placement of the battery 100 in the buffer space 22 and its engagement with the clamping assembly 20. Furthermore, this configuration allows the volume of the buffer space 22 to be adjusted in another direction, such as the third direction Z, to accommodate the caching of batteries 100 of varying lengths and widths, ensuring adequate storage.

[0103] As shown in Figures 3 to 5. The cache device 400 provided in the embodiment of the present application includes a support member 10, a clamping assembly 20 and a driving assembly 30. The support member 10 includes a guide portion 11 extending along a first direction X and a support portion 12 and a bearing portion 13 extending along a second direction Y. The guide portion 11 includes two beams 111 distributed along a third direction Z. The beams 111 are respectively connected to the support portions 12 at both ends of the first direction X. The bearing portion 13 is connected between two adjacent beams 111. The driving assembly 30 is at least partially connected to the bearing portion 13. The end face of the beam 111 in the third direction Z is provided with a slide rail 112. The clamping assembly 20 is provided on the support member 10. The clamping assembly 20 includes a pair of clamping portions 21. The pair of clamping portions 21 forms a cache space 22 for placing the battery 100. There are multiple clamping assemblies 20 distributed along the first direction X. The clamping parts 21 arranged in pairs are all provided on the guide part 11. Each clamping part 21 is movably connected to the crossbeam 111. Specifically, a slider 23 can be provided on the clamping part 21, and the slider 23 is slidably connected to the slide rail 112. The clamping part 21 includes a mounting frame 211 and a limit plate 212. The mounting frame 211 is connected to the support member 10. The limit plate 212 is connected to the mounting frame 211 and is used to support the battery 100. The mounting frame 211 includes a connecting beam 211a and a limit beam 211b. The connecting beam 211a is provided with a limit beam 211b at both ends of its own extension direction. The connecting beam 211a is connected to the support member 10. One end of the limit beam 211b is connected to the connecting beam 211a and the other end is provided with a limit plate 212. The first direction X, the second direction Y, and the third direction Z are arranged perpendicular to each other. The driving assembly 30 includes a telescopic member connected between the clamping parts 21 arranged in pairs. The number of the driving assembly 30 is the same as that of the clamping assemblies 20 and they are arranged one-to-one. The driving assembly 30 is at least partially connected to the bearing part 13.

[0104] On the other hand, an embodiment of the present application further provides a battery swap station, comprising the above-mentioned cache device 400.

[0105] The battery swap station provided in the embodiment of the present application includes the cache device 400 provided in the above embodiment. When used to replace the battery 100, the cache device 400 can provide a cache for the replaced battery 100. During caching, the battery 100 to be cached can be placed in the cache space 22 formed by the pair of clamping parts 21, and the battery 100 can be cached by the clamping assembly 20. Because the driving assembly 30 is connected to at least one of the pair of clamping parts 21 and drives at least one clamping part 21 to move relative to the support member 10 to adjust the volume of the cache space 22, the cache device 400 can adjust the volume of the cache space 22 to match the volume of the battery 100 by driving the clamping part 21 to move according to the size of the battery 100 to be cached, thereby caching different types of batteries 100 and improving the versatility of the cache device 400.
