[0024] like Figures 1 to 5 As shown, in at least one embodiment, a heat-insulating battery box is provided, comprising: a shell 1, a pair of baffles 11 are arranged in the shell 1, the two baffles 11 are arranged in parallel, and a plurality of partition mechanisms 2 are arranged equidistantly between the two baffles 11, and the partition mechanisms 2 are arranged perpendicular to the baffles 11; the partition mechanisms 2 are suitable for dividing the space between the two baffles 11 into a plurality of battery pack storage areas, and the partition mechanisms 2 are suitable for connecting or separating adjacent battery pack storage areas; the division of the battery pack storage areas in the battery box shell 1 is realized, which facilitates the diffusion of heat between adjacent battery pack storage areas, and the battery pack storage areas can be separated in case of danger to avoid the spread of danger.

[0025] The partition mechanism 2 includes: a partition plate 21 and a filling piece 22; the partition plate 21 is arranged between two baffles 11, the partition plate 21 is arranged perpendicular to the baffles 11, and the partition plate 21 is inserted into the corresponding baffle 11; the partition plate 21 is hollow, the filling piece 22 is arranged in the partition plate 21, and the filling piece 22 is suitable for moving in the partition plate 21; both sides of the partition plate 21 in the length direction are open, and the filling piece 22 is suitable for moving out from the opening; the filling piece 22 is smaller than the space inside the partition plate 21, that is, the thickness of the filling piece 22 can correspond to the thickness of the internal space of the partition plate 21, the outer wall of the filling piece 22 can contact the inner wall of the internal space of the partition plate 21, and the length of the filling piece 22 is smaller than the length of the internal space of the partition plate 21, so that the filling piece 22 can be easily moved inside the partition plate 21; the partition plate 21 can be connected to the baffle 11 by inserting the partition plate 21 into the card slot 12, and the connection through the card slot 12 can facilitate the disassembly and assembly of the partition plate 21.

[0026] A plurality of first through holes 211 are provided on the side wall in the thickness direction of the partition plate 21; a plurality of second through holes 221 are provided on the side wall in the thickness direction of the filling piece 22, and the second through holes 221 correspond to the first through holes 211; when the partition plate 21 is installed on the baffle 11, the position of the filling piece 22 in the partition plate 21 can make the part of the filling piece 22 without the second through hole 221 block the first through hole 211 on the partition plate 21, so that the shell 1 can avoid dust and impurities from clogging the first through hole 211 and the second through hole 221 during the placement process.

[0027] A strip hole 212 is horizontally opened on the side wall of the partition plate 21 in the thickness direction; a rubber strip 222 is connected to the side wall of the filling piece 22 in the thickness direction through a connecting piece, and the strip hole 212 facilitates the movement of the connecting piece, so that the filling piece 22 can be driven to move during the movement of the rubber strip 222; the rubber strip 222 is vertically arranged on the side wall of the partition plate 21 in the thickness direction; when the battery pack is installed in the corresponding battery pack storage area, the battery pack may be first inserted obliquely into the corresponding battery pack storage area during the placement process, and then the battery pack is placed flat in the battery pack storage area, the battery pack will contact the rubber strip 222, driving the rubber strip 222 to move, and the filling piece 22 is driven to move by the movement of the rubber strip 222, so that the first through hole 211 is gradually aligned with the second through hole 221, and when the battery pack is completely placed in the corresponding battery pack storage area, the first through hole 211 is completely aligned with the corresponding second through hole 221, so that the first through hole 21 1 is opened, at this time, the rubber strip 222 moves to between the card slot 12 and the partition plate 21, and part of the rubber strip 222 is located in the battery pack storage area, the rubber strip 222 located between the card slot 12 and the partition plate 21 can make the card slot 12 and the partition plate 21 sealed, part of the rubber strip 222 located in the battery pack storage area contacts the battery pack, limits and clamps the side wall of the battery pack, and the battery pack maintains the position of the filler 22 through the rubber strip 222, so that the first through hole 211 and the second through hole 221 are kept in an aligned state; the first through hole 211 is in an open state after the battery pack is installed, so that the heat in the battery pack storage area can be diffused; the rubber strip 222 can melt and deform when subjected to a certain temperature, and the temperature can be set according to the safety temperature of the battery box, that is, the corresponding rubber material is selected to make the rubber strip 222, so that the rubber strip 222 can melt and deform when the temperature in the battery pack storage area is higher than the safety temperature.

[0028] The partition plate 21 is provided with an injection hole 213 on the top surface, and the injection hole 213 is connected to the inside of the partition plate 21. The filler 22 is provided with a strip groove 223 on the top surface, and the strip groove 223 is connected to a side wall of the filler 22 in the length direction; the baffle 11 is provided with a storage slot 13 on the side facing the battery pack storage area, and the storage slot 13 is connected to the card slot 12; the storage slot 13 is covered with a film 14; when the battery pack is completely placed in the corresponding battery pack storage area, the injection hole 213 corresponds to the strip groove 223, and at this time, inert gas is injected through the injection hole 213, and the inert gas is injected into the empty part inside the partition through the strip groove 223, and the inert gas can enter the storage slot 13. As the injected inert gas increases, the pressure in the storage slot 13 increases, squeezing the film 14 outward, so that the film 14 bulges out, and the bulging film 14 will contact the battery pack to limit and clamp the battery pack, and the rubber strip 222 and the film 14 can be used from The battery pack is clamped in two directions to prevent the battery pack from moving during the entire use of the battery box; when the battery pack is abnormal, for example, the temperature of the battery pack suddenly increases, the temperature of the storage area of ​​a single battery pack cannot be diffused in time, which will cause the temperature to be too high. The excessively high temperature will cause the rubber strip 222 to melt and deform, and the rubber strip 222 will not contact the battery pack. At this time, the high-pressure gas in the storage slot 13 will squeeze the filler 22 to make the filler 22 move, and the filler 22 will block the first through hole 211 to prevent the high temperature from spreading to other battery pack storage areas, and the inert gas will enter the battery pack storage area from between the baffle 11 and the card slot 12 that cannot be sealed, and the high temperature will damage the film 14 to release the inert gas in the storage slot 13, so as to prevent the battery pack from catching fire due to high temperature and affecting adjacent battery packs; after the inert gas injection is completed, the gas injection hole 213 can be blocked.

[0029] The baffle plate 11 is provided with a slot 12 corresponding to the partition plate 21 for fixing the partition plate 21 .

[0030] The top surface of the shell 1 is open, and a cover plate 15 is provided on the top surface of the shell 1 to facilitate placing the battery pack in the corresponding battery pack storage area.
