Referring to fig. 1, a battery cabinet 11 is provided in an embodiment of the present application, and the battery cabinet 11 is used for placing a battery box 12 and a high-voltage box to provide a bearing function for the battery box 12 and the high-voltage box. In this embodiment, the battery cabinet 11 can solve the technical problem that the difficulty in assembling and disassembling the battery box 12 in the prior art is high.

In the present embodiment, referring to fig. 2 and 3 in combination, the battery cabinet 11 includes a frame body 100, a support beam 200, and a mounting beam 300. The supporting beam 200 comprises a fixed beam 210, a lifting beam 220 and a lifting device 230, wherein the fixed beam 210 is fixedly connected with the frame main body 100, the lifting device 230 is arranged on the fixed beam 210, the lifting beam 220 is connected with the lifting device 230, and the lifting device 230 is used for driving the lifting beam 220 to lift relative to the fixed beam 210. The mounting beam 300 is connected to the fixing beam 210, a mounting surface 301 for mounting the battery box 12 is provided on the mounting beam 300, and a plurality of rolling members 310 protruding from the mounting surface 301 are provided on the mounting beam 300. The lifting device 230 is used for driving the lifting beam 220 to lower than the plane of the assembly surface 301, and the lifting device 230 is also used for driving the lifting beam 220 to rise above the rolling element 310.

In the above-mentioned process of assembling the battery box 12, the height of the lifting beam 220 can be lowered by the lifting device 230, so that the lifting beam 220 is lower than the assembling beam 300; the battery box 12 is then placed on the mounting beam 300, and the rolling members 310 are provided on the mounting beam 300, so that the battery box 12 can be easily loaded by the rolling members 310. After the battery box 12 is slid to a designated position with respect to the mounting beam 300, the lifting beam 220 may be lifted by the lifting device 230 such that the lifting beam 220 is higher than the rolling members 310, thereby causing the lifting beam 220 to carry the battery box 12. When the battery box 12 is disassembled, the lifting beam 220 can be lowered by the lifting device 230 so that the lifting beam 220 is lower than the assembling surface 301, the battery box 12 can be placed on the assembling beam 300, and the battery box 12 can be easily disassembled by the rolling action of the rolling piece 310. Based on this, in the battery cabinet 11 and the energy storage device 10, the technical problem of high difficulty in assembling and disassembling the battery box 12 in the prior art can be improved. Meanwhile, the battery box 12 is installed or removed in a rolling mode, so that the paint on the battery box 12 can be prevented from being scratched, and the problem that the battery box 12 is easy to rust is avoided.

In the present embodiment, in the case of taking one battery box 12 as an example, there are two support beams 200 and two mounting beams 300. Two support beams 200 are provided at a distance, and two assembly beams 300 are provided between two fixing beams 210. During assembly of the battery box 12, opposite sides of the battery box 12 are slid over the assembly beams 300, respectively, and after the battery box 12 is assembled, the opposite sides of the battery box 12 are carried by the two lifting beams 220, respectively.

Alternatively, referring to fig. 2 and 4 in combination, in order to further enhance the convenience of assembly of the battery box 12, the battery case 11 further includes a rotation shaft 302, and the middle portion of the assembly beam 300 is rotatably coupled with the fixing beam 210 through the rotation shaft 302 so that the assembly beam 300 can be tilted forward or backward. It should be noted that referring to fig. 5, the two ends of the assembly beam 300 are a first end 304 and a second end 305, respectively, and the battery box 12 moves from the first end 304 to the second end 305 when the battery box 12 is assembled; when the battery box 12 is removed, the battery box 12 is moved from the second end 305 to the first end 304 and removed from the first end 304. Based on this, the assembly beam 300 rotates relative to the fixing beam 210 until the second end 305 is higher than the first end 304, so that the battery box 12 can be easily removed under the self-gravity of the battery box 12; correspondingly, the assembly beam 300 rotates relative to the fixing beam 210 to the first end 304 higher than the second end 305 to incline backward, and at this time, the battery box 12 can be conveniently installed under the gravity action of the battery box 12.

That is, in the present embodiment, since the mounting beam 300 can be rotated with respect to the fixing beam 210 to tilt the mounting beam 300 forward or backward, the mounting beam 300 can be tilted backward during the assembly process to reduce the difficulty of loading the battery box 12; the assembly beam 300 can be inclined forwards when the battery box 12 is detached, so that the difficulty in detaching the battery box 12 is reduced, and the assembly and disassembly difficulties of the battery box 12 are further reduced.

It should be noted that, in other embodiments of the present application, the arrangement of the rotation shaft 302 may be omitted, that is, in other embodiments, the assembly beam 300 may be fixedly arranged relative to the fixing beam 210, and the rolling member 310 may be arranged to reduce the assembly difficulty of the battery box 12.

In the above description, the lifting beam 220 is lower than the mounting surface 301 and the lifting beam 220 is higher than the rolling member 310 with reference to the mounting beam 300 being in a normal state, that is, with reference to the case where the heights of the first end 304 and the second end 305 are equal.

After the assembly beam 300 rotates relative to the fixed beam 210, the limiting piece 211 may move in the limiting groove 330 until the limiting piece 211 abuts against the inner wall of the limiting groove 330, thereby limiting the assembly beam 300. On the one hand, the overturning amplitude of the assembly beam 300 can be limited, on the other hand, after the assembly beam 300 rotates in place, the assembly beam 300 can be provided with bearing through the limiting piece 211, so that the stability of the assembly beam 300 is ensured, and the battery box 12 can be smoothly assembled or disassembled.

Wherein, the first driving part 322 can be propped against the inner wall above the matching groove 303, and in the process of continuing to move the first driving part 322, the assembly beam 300 can be enabled to tilt backwards; correspondingly, the second driving part 323 can abut against the inner wall below the matching groove 303, and in the process of continuing to move the second driving part 323, the assembly beam 300 can be enabled to tilt forward.

It should be noted that, after the first driving portion 322 drives the assembly beam 300 to tilt backward, the second driving portion 323 is staggered from the mating groove 303; similarly, after the second driving portion 323 drives the assembly beam 300 to incline forward, the first driving portion 322 is staggered from the mating groove 303.

And/or, the second driving part 323 is provided with an inclined second driving surface 3231 at a side far away from the first driving part 322, and the thickness of the second driving part 323 is gradually reduced; the second driving surface 3231 is for abutting against the other groove wall of the mating beam 303 to drive the mounting beam 300.

It should be noted that, in the case where the first driving surface 3221 is omitted, the inner wall of the matching groove 303 corresponding to the first driving portion 322 may be obliquely arranged, so that when the first driving portion 322 abuts against the inner wall of the matching groove 303, the assembly beam 300 is driven to tilt backwards; similarly, in the case where the second driving surface 3231 is omitted, the inner wall of the coupling groove 303 corresponding to the second driving portion 323 may be inclined, so that the second driving portion 323 may be pushed against the inner wall of the coupling groove 303 to drive the mounting beam 300 to tilt forward.

Further, the driving device 320 further includes a first operation portion 324 and a second operation portion 325; the first operating part 324 is movably connected with the fixing piece 321 and can move relative to the fixing piece 321 to drive the first driving part 322 to move; the second operating portion 325 is movably connected to the fixing member 321, and is movable relative to the fixing member 321 to drive the second driving portion 323 to move.

The first elastic member 3242 can provide tension to the first operating portion 324 by elastic potential energy thereof under the condition of being compressed, so that the threaded fit between the first operating portion 324 and the fixing member 321 forms self-locking, thereby ensuring the position stability of the first operating portion 324 after the first driving portion 322 is operated, and further ensuring the position stability of the first driving portion 322.

In this embodiment, referring to fig. 8, the lifting device 230 includes a driving shaft 231 and a driving assembly; the drive assembly includes a first link 232, a second link 233, two movable members 235, and a plurality of third links 234; the first connecting piece 232 is connected to the lifting beam 220, the second connecting piece 233 is connected to the fixed beam 210, two ends of the first connecting piece 232 are hinged with the third connecting pieces 234, and one ends of the two third connecting pieces 234, which are far away from the first connecting piece 232, are respectively hinged with the two movable pieces 235; two ends of the second connecting piece 233 are hinged with the other two third connecting pieces 234, and one ends of the two third connecting pieces 234 far away from the second connecting piece 233 are respectively hinged with the two movable pieces 235; the driving shaft 231 is connected with the two movable members 235 to drive the two movable members 235 toward or away from each other so that the first link 232 and the second link 233 are away from or toward each other.

When the driving shaft 231 drives the two movable members 235 to move away from each other, the two movable members 235 drive the four third connecting members 234 to be unfolded, so that the first connecting members 232 and the second connecting members 233 are close to each other, and the lifting beam 220 and the fixed beam 210 are close to each other, thereby completing the lowering of the lifting beam 220. Similarly, when the driving shaft 231 drives the two movable members 235 to approach each other, the two movable members 235 drive the four third connecting members 234 to retract, so that the first connecting members 232 and the second connecting members 233 are far away from each other, and the lifting beam 220 and the fixed beam 210 are far away from each other, thereby completing the lifting of the lifting beam 220.

It should be appreciated that in other embodiments of the present application, the lifting device 230 between the lifting beam 220 and the fixed beam 210 may be configured in other manners, for example, the lifting device 230 is a motor lifting device 230, a cam lifting device 230, a hydraulic device, or the like.

Based on the above-mentioned battery cabinet 11, referring to fig. 1, an energy storage device 10 is further provided in the embodiment of the present application, and the energy storage device 10 adopts the above-mentioned battery cabinet 11. Based on this, the energy storage device 10 can solve the technical problem of high difficulty in assembling and disassembling the battery box 12 in the prior art; and the problem that the battery box 12 is easily scratched to cause easy rusting can be avoided.

In summary, in the battery cabinet 11, during the assembly process of the battery box 12, the height of the lifting beam 220 can be reduced by the lifting device 230, so that the lifting beam 220 is lower than the assembly beam 300; the battery box 12 is then placed on the mounting beam 300, and the rolling members 310 are provided on the mounting beam 300, so that the battery box 12 can be easily loaded by the rolling members 310. After the battery box 12 is slid to a designated position with respect to the mounting beam 300, the lifting beam 220 may be lifted by the lifting device 230 such that the lifting beam 220 is higher than the rolling members 310, thereby causing the lifting beam 220 to carry the battery box 12. When the battery box 12 is disassembled, the lifting beam 220 can be lowered by the lifting device 230 so that the lifting beam 220 is lower than the assembling surface 301, the battery box 12 can be placed on the assembling beam 300, and the battery box 12 can be easily disassembled by the rolling action of the rolling piece 310. Based on this, in the battery cabinet 11 and the energy storage device 10, the technical problem of high difficulty in assembling and disassembling the battery box 12 in the prior art can be improved. Meanwhile, the battery box 12 is installed or removed in a rolling mode, so that the paint on the battery box 12 can be prevented from being scratched, and the problem that the battery box 12 is easy to rust is avoided. Further, since the mounting beam 300 can be rotated with respect to the fixing beam 210 to tilt the mounting beam 300 forward or backward, the mounting beam 300 can be tilted backward during the assembly process to reduce the difficulty of loading the battery box 12; the assembly beam 300 can be inclined forwards when the battery box 12 is detached, so that the difficulty in detaching the battery box 12 is reduced, and the assembly and disassembly difficulties of the battery box 12 are further reduced.
