TECHNICAL FIELD

[0001] The present application relates to the technical field of energy storage devices, and particularly relates to a data recording device and an energy storage device. BACKGROUND

[0002] The energy storage device may have a thermal runaway phenomenon in some cases, causing a fire and explosion in the device. The data storage chip in the device may fail under the dual influence of the fire and the fire extinguishing liquid, causing the device operation data before the thermal runaway to be unable to be restored later, which is not conducive to the subsequent analysis of the accident cause. CONTENT OF THE UTILITY MODEL

[0003] Therefore, the present application provides a data recording device and an energy storage device, which can improve the safety of the chip module storing data under the influence of the fire and the fire extinguishing liquid.

[0004] An embodiment of the present application provides a data recording device applied to an energy storage device. The data recording device comprises a shell assembly and a data recording piece. The shell assembly comprises a waterproof shell, a fire-resistant and heat-resistant shell and an anti-impact shell. The waterproof shell is arranged in the anti-impact shell. The fire-resistant and heat-resistant shell is arranged between the waterproof shell and the anti-impact shell. The fire-resistant and heat-resistant shell wraps the waterproof shell. The shell assembly is provided with a wire outlet channel. The wire outlet channel passes through the waterproof shell, the fire-resistant and heat-resistant shell and the anti-impact shell to connect the inside of the waterproof shell and the outside of the anti-impact shell. The data recording piece comprises a chip module and an electric connection wire. The chip module is arranged in the waterproof shell. One end of the electric connection wire is connected with the chip module, and the other end of the electric connection wire extends to the outside of the anti-impact shell through the wire outlet channel.

[0005] The chip module is connected with the battery management device of the energy storage device through the electric connection wire to record the operation data of the energy storage device. The waterproof shell is arranged in the fire-resistant and heat-resistant shell, which is beneficial to avoid damage of the waterproof shell caused by the fire or high temperature under the protection of the fire-resistant and heat-resistant shell, so that the waterproof shell can block the fire extinguishing liquid from contacting the chip module, thereby achieving double protection of the chip module. The anti-impact shell is arranged outside the fire-resistant and heat-resistant shell, and the anti-impact shell can resist explosion impact, which is beneficial to avoid failure of the fire-resistant and heat-resistant shell and the waterproof shell caused by the impact or the penetration of the splashed fragments, thereby prolonging the effective working time of the fire-resistant and heat-resistant shell and the waterproof shell, and improving the double protection effect of the chip module.

[0006] In some embodiments of the present application, the waterproof shell and the fire-resistant and heat-resistant shell are arranged at least partially spaced apart to form a first separation space.

[0007] By arranging the first separation space between the waterproof shell and the fire-resistant and heat-resistant shell, the contact between the waterproof shell and the fire-resistant and heat-resistant shell is reduced, and the difficulty of heat transfer from the fire-resistant and heat-resistant shell to the waterproof shell is increased, thereby being beneficial to avoid overheating damage of the waterproof shell and being beneficial to prevent overheating damage of the chip module.

[0008] In some embodiments of the present application, the waterproof shell is provided with a slot. The chip module is inserted into the slot to be fixed relative to the waterproof shell.

[0009] The chip module can be fixed in the waterproof shell through the slot, which is beneficial to avoid damage to the chip module and reduce the shaking of the electric connection line to avoid affecting the structure at the wire outlet passage, thereby maintaining the fireproof, heat-insulating and waterproof effects of the shell assembly at the wire outlet passage.

[0010] In some embodiments of the present application, the waterproof shell includes a waterproof shell body, a waterproof shell cover and a waterproof plug. The chip module is arranged in the waterproof shell body. The waterproof shell cover is arranged on the waterproof shell body, and the waterproof shell cover and the waterproof shell body are sealingly matched. The waterproof shell cover is provided with a connecting hole. Part of the wire outlet passage is arranged in the waterproof plug. The waterproof plug is arranged in the connecting hole, and the waterproof plug is configured to be elastically deformed by being extruded by the waterproof shell cover and the electric connection line.

[0011] The waterproof shell cover is arranged on the waterproof shell body in a form convenient for disassembly and assembly, which facilitates the arrangement of the chip module in the waterproof shell. The waterproof plug is arranged to improve the waterproof effect of the electric connection line passing through the waterproof shell cover.

[0012] In some embodiments of the present application, the fire-resistant and heat-resistant shell includes a fire-resistant and heat-resistant shell body and a fire-resistant and heat-resistant shell cover. The waterproof shell is arranged in the fire-resistant and heat-resistant shell body. The fire-resistant and heat-resistant shell cover is arranged on the fire-resistant and heat-resistant shell body. Part of the wire outlet passage is arranged in the fire-resistant and heat-resistant shell cover. The impact-resistant shell includes an impact-resistant shell body and an impact-resistant shell cover. The fire-resistant and heat-resistant shell is arranged in the impact-resistant shell body. The impact-resistant shell cover is arranged on the impact-resistant shell body. The impact-resistant shell cover and the impact-resistant shell body are fixedly connected. Part of the wire outlet passage is arranged in the impact-resistant shell cover. The impact-resistant shell cover abuts against the fire-resistant and heat-resistant shell cover, so that the fire-resistant and heat-resistant shell cover is attached to the fire-resistant and heat-resistant shell body in the covering direction.

[0013] The fire-resistant and heat-resistant shell cover is arranged on the fire-resistant and heat-resistant shell body in a form convenient for disassembly and assembly, which facilitates the arrangement of the waterproof shell in the fire-resistant and heat-resistant shell. The impact-resistant shell cover is arranged on the impact-resistant shell body in a form convenient for disassembly and assembly, which facilitates the arrangement of the fire-resistant and heat-resistant shell in the impact-resistant shell. The impact-resistant shell cover presses the fire-resistant and heat-resistant shell cover on the fire-resistant and heat-resistant shell body, which improves the sealing effect between the fire-resistant and heat-resistant shell cover and the fire-resistant and heat-resistant shell body, thereby improving the fireproof and heat-insulating effects of the fire-resistant and heat-resistant shell.

[0014] In some embodiments of the present application, the fire-resistant and heat-resistant shell further includes a fire-resistant and heat-resistant baffle. The fire-resistant and heat-resistant baffle is located on the side of the fire-resistant and heat-resistant shell cover away from the fire-resistant and heat-resistant shell body. The fire-resistant and heat-resistant baffle and the fire-resistant and heat-resistant shell cover are spaced apart to form a second separation space. Part of the wire outlet passage is arranged in the fire-resistant and heat-resistant baffle.

[0015] The outlet channel passes through the fire-resistant heat-resistant shell cover and the impact-resistant shell cover. The fire-resistant heat-resistant baffle is arranged between the fire-resistant heat-resistant shell cover and the impact-resistant shell cover, so that the heat insulation effect of the shell assembly at the outlet channel is improved. A second separation space is arranged between the fire-resistant heat-resistant baffle and the fire-resistant heat-resistant shell cover, so that the contact between the fire-resistant heat-resistant baffle and the fire-resistant heat-resistant shell cover is reduced, the difficulty of heat passing through the fire-resistant heat-resistant baffle and the fire-resistant heat-resistant shell cover to the waterproof shell is increased, and the fireproof heat insulation effect of the fire-resistant heat-resistant shell is improved.

[0016] In some embodiments of the present application, along the distribution direction of the fire-resistant heat-resistant shell cover and the fire-resistant heat-resistant baffle, the projection of the part of the outlet channel arranged in the fire-resistant heat-resistant shell cover and the projection of the part of the outlet channel arranged in the fire-resistant heat-resistant baffle are separated.

[0017] The path of the outlet channel from the impact-resistant shell to the waterproof shell through the fire-resistant heat-resistant shell extends in a winding manner, so that hot air cannot directly pass through the waterproof shell, and the heat insulation effect of the fire-resistant heat-resistant shell is improved. The electric connection line also extends in a winding manner in the outlet channel, so that it can be supported between the fire-resistant heat-resistant baffle and the fire-resistant heat-resistant shell cover to maintain the state of the fire-resistant heat-resistant baffle and the fire-resistant heat-resistant shell cover being arranged at intervals, thereby improving the fireproof heat insulation effect of the fire-resistant heat-resistant shell.

[0018] In some embodiments of the present application, the impact-resistant shell cover includes an impact-resistant cover and a fixing block. The impact-resistant cover and the fixing block are connected. The edge of the fire-resistant heat-resistant baffle is provided with a clearance. The fixing block passes through the clearance and abuts against the fire-resistant heat-resistant shell cover.

[0019] The impact-resistant cover can be arranged on the impact-resistant shell body to maintain the sealing effect of the impact-resistant shell. By arranging the fixing block capable of passing through the fire-resistant heat-resistant baffle, the pressing of the impact-resistant shell cover on the fire-resistant heat-resistant shell cover and the state of the fire-resistant heat-resistant baffle and the fire-resistant heat-resistant shell cover being arranged at intervals can be maintained, which is beneficial to improving the fireproof heat insulation effect of the fire-resistant heat-resistant shell.

[0020] In some embodiments of the present application, the inner side wall of the impact-resistant shell body is provided with a fixing groove. Part of the fixing block is clamped in the fixing groove. The fire-resistant heat-resistant baffle abuts against the side of the fixing block away from the fixing groove to stop the fixing block from disengaging from the fixing groove. The impact-resistant cover and the fixing block are fixedly connected.

[0021] The impact-resistant cover is longitudinally arranged on the impact-resistant shell body, and the fixing block is transversely inserted into the impact-resistant shell body. The impact-resistant cover and the fixing block are longitudinally fixedly connected, so that the impact-resistant cover is provided with longitudinal force, and the impact-resistant cover can press the fire-resistant heat-resistant shell longitudinally. The fixing block can be detached from the impact-resistant shell body, so that the inner diameter of the impact-resistant shell body can be increased to avoid hindering the fire-resistant heat-resistant shell from entering the impact-resistant shell body, and the outer diameter of the impact-resistant shell body can be reduced to reduce the occupied space of the impact-resistant shell in the energy storage device and facilitate the adjustment of the setting position of the data recording device in the energy storage device.

[0022] An embodiment of the present application provides a power storage device.

[0036] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments of the present application.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application.

[0038] In some cases, the energy storage device can have a thermal runaway phenomenon, causing a fire and explosion in the device. The data storage chip module in the device can fail under the dual influence of fire and fire extinguishing liquid, making it impossible to restore the device operation data before the thermal runaway in the later stage, which is not conducive to the post-mortem of the accident cause.

[0039] The embodiments of the present application provide a data recording device applied to an energy storage device. The data recording device comprises a shell assembly and a data recording piece. The shell assembly comprises a waterproof shell, a fire-resistant and heat-resistant shell, and an impact-resistant shell. The waterproof shell is arranged in the impact-resistant shell. The fire-resistant and heat-resistant shell is arranged between the waterproof shell and the impact-resistant shell. The fire-resistant and heat-resistant shell wraps the waterproof shell. The shell assembly is provided with a wire outlet channel. The wire outlet channel passes through the waterproof shell, the fire-resistant and heat-resistant shell, and the impact-resistant shell to communicate the inside of the waterproof shell and the outside of the impact-resistant shell. The data recording piece comprises a chip module and an electric connecting wire. The chip module is arranged in the waterproof shell. The electric connecting wire is connected with the chip module. The electric connecting wire extends out to the outside of the impact-resistant shell through the wire outlet channel.

[0040] The chip module is connected with the battery management device of the energy storage device through the electric connection line to record the operation data of the energy storage device. The waterproof shell is arranged in the fire-resistant and heat-resistant shell, and is protected by the fire-resistant and heat-resistant shell, so that damage of the waterproof shell caused by fire or high temperature is avoided, and the waterproof shell can block the contact of the chip module with the fire extinguishing liquid, so that the chip module is double-protected. The impact-resistant shell is arranged outside the fire-resistant and heat-resistant shell, and the impact-resistant shell can resist explosion impact, so that the fire-resistant and heat-resistant shell and the waterproof shell are prevented from being pierced by impact or splashed fragments, the effective working time of the fire-resistant and heat-resistant shell and the waterproof shell is prolonged, and the double-protection effect of the chip module is improved.

[0041] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0042] Referring to Figures 1 to 3 An embodiment of the present application provides a data recording device 100 and an energy storage device 200.

[0043] In some embodiments, the energy storage device 200 has the functions of storing and discharging electricity, and is used for home power backup, production unit power backup, outdoor work, outdoor entertainment, etc. The data recording device 100 is used to record the operation data of the energy storage device 200.

[0044] In some embodiments, the energy storage device 200 includes a device shell 201, a battery module 202 and a battery management device 203. The battery module 202 and the battery management device 203 are electrically connected and are both arranged in the device shell 201. For example, the battery management device 203 can be a BMS (Battery Management System) board.

[0045] In some embodiments, the energy storage device 200 further includes a power conversion module (not shown in the figure). The power conversion module is electrically connected with the battery module 202, and is used to realize AC / DC conversion control of the output current of the battery module 202. The energy storage device 200 provided with the power conversion module can be a small portable power supply, a household energy storage power supply, an industrial and commercial energy storage power supply or a container type energy storage power supply, etc.

[0046] In some embodiments, the power conversion module can be omitted. The energy storage device 200 without the power conversion module can be used independently. The energy storage device 200 without the power conversion module can usually only output DC power. When the energy storage device 200 without the power conversion module is used independently, it can be used in coordination with the energy storage device 200 provided with the power conversion module as an additional battery capacity power supply system.

[0047] Referring to Figure 1 , Figure 3and Figure 4 In some embodiments, the energy storage device 200 further comprises a data recording device 100. The data recording device 100 is disposed in the device housing 201 and connected with the battery management device 203. For example, the data recording device 100 and the battery management device 203 are both disposed in the housing of the battery module 202, and the data recording device 100 is located beside the battery cell of the battery module 202 and avoids the spray path of the battery cell, wherein, Figure 3 The structure indicated by the reference sign of the battery module 202 is the battery cell of the battery module 202.

[0048] Referring to Figures 3 to 5 In some embodiments, the data recording device 100 comprises a housing assembly 10 and a data recording piece 20. The housing assembly 10 is provided with a wire outlet channel 14. The wire outlet channel 14 communicates the inside and outside of the housing assembly 10. The data recording piece 20 comprises a chip module 21 and an electric connecting wire 22. The chip module 21 is disposed in the housing assembly 10. One end of the electric connecting wire 22 is connected with the chip module 21, and the other end extends out of the housing assembly 10 through the wire outlet channel 14. The other end of the electric connecting wire 22 is connected with the battery management device 203, so that the chip module 21 records the operation data of the battery management device 203. For example, the chip module 21 is a circuit board with data storage function.

[0049] The chip module 21 is connected with the battery management device 203 through the electric connecting wire 22 to record the operation data of the energy storage device 200, especially the operation data of the battery module 202 and the battery management device 203. Moreover, the chip module 21 is disposed in the housing assembly 10 to reduce the influence of fire and fire extinguishing liquid, so that the chip module 21 can restore the operation data of the energy storage device 200, thereby facilitating the review of the accident cause.

[0050] Referring to Figures 4 to 6 In some embodiments, the housing assembly 10 comprises a waterproof shell 11, a fire-resistant and heat-resistant shell 12, and an impact-resistant shell 13. The waterproof shell 11 is disposed in the impact-resistant shell 13. The fire-resistant and heat-resistant shell 12 is disposed between the waterproof shell 11 and the impact-resistant shell 13, and the fire-resistant and heat-resistant shell 12 wraps the waterproof shell 11. The wire outlet channel 14 passes through the waterproof shell 11, the fire-resistant and heat-resistant shell 12, and the impact-resistant shell 13 to communicate the inside of the waterproof shell 11 and the outside of the impact-resistant shell 13. The chip module 21 is disposed in the waterproof shell 11. The other end of the electric connecting wire 22 extends out of the impact-resistant shell 13 through the wire outlet channel 14.

[0051] The waterproof housing 11 is housed inside the flame-resistant and heat-insulating housing 12. Under the protection of the flame-resistant and heat-insulating housing 12, it helps to prevent fire or high temperatures from damaging the waterproof housing 11, thus enabling the waterproof housing 11 to prevent fire extinguishing liquids from contacting the chip module 21, thereby providing double protection for the chip module 21. The impact-resistant housing 13 is located outside the flame-resistant and heat-insulating housing 12. The impact-resistant housing 13 can withstand shock and explosion impacts, which helps to prevent the flame-resistant and heat-insulating housing 12 and the waterproof housing 11 from failing due to impacts or flying fragments, thereby increasing the effective working time of the flame-resistant and heat-insulating housing 12 and the waterproof housing 11, and thus improving the effect of double protection for the chip module 21.

[0052] For example, the waterproof shell 11 can be made of materials such as plastic or metal, so that the waterproof shell 11 itself has a dense structure to prevent liquid from entering the interior, which facilitates the construction of a waterproof sealed cavity for the chip module 21. For example, the flame-resistant and heat-resistant shell 12 can be made of materials such as ceramic silicone or aluminum silicate, so that the flame-resistant and heat-resistant shell 12 has a high melting point and low thermal conductivity, so that it can maintain high stability under fire or high temperature and reduce the heat transferred inward. For example, the impact-resistant shell 13 can be made of materials such as metal, so that the impact-resistant shell 13 has a rigid structure, so that after receiving the shock wave from the valve of the battery module 202 or the shock wave and fragments generated by the explosion, the deformation of the impact-resistant shell 13 is small, thereby reducing the damage to the flame-resistant and heat-resistant shell 12.

[0053] In some embodiments, the chip module 21 is coated with a waterproof adhesive to improve its waterproof performance. For example, the waterproof adhesive may be a silicone conformal adhesive.

[0054] In some embodiments, the outside of the electrical connection line 22 is wrapped or wrapped with a flame-retardant and heat-resistant fabric to enhance the fire and heat insulation protection of the electrical connection line 22, which helps to prevent fire or high temperature from spreading along the electrical connection line 22 to the chip module 21 and damaging the chip module 21.

[0055] See Figure 6 In some embodiments, the waterproof shell 11 and the flame-retardant and heat-resistant shell 12 are at least partially spaced apart to form a first partition space 15.

[0056] By configuring a first partition space 15 between the waterproof housing 11 and the flame-resistant and heat-insulating housing 12, the contact between the waterproof housing 11 and the flame-resistant and heat-insulating housing 12 is reduced, which increases the difficulty of heat transfer from the flame-resistant and heat-insulating housing 12 to the waterproof housing 11. This helps to avoid overheating damage to the waterproof housing 11 and also helps to prevent overheating damage to the chip module 21.

[0057] Understandably, in some embodiments, the first partition space 15 is configured to form a negative pressure relative to atmospheric pressure in order to improve the thermal insulation effect.

[0058] SeeFigure 5 and Figure 6 In some embodiments, the waterproof shell 11 is provided with a slot 1111. The chip module 21 is inserted into the slot 1111 to be fixed relative to the waterproof shell 11.

[0059] The chip module 21 can be fixed in the waterproof shell 11 through the slot 1111, which is beneficial to avoid damage to the chip module 21 and reduce the shaking of the electric connection line 22 to avoid affecting the structure at the outlet passage 14, thereby maintaining the fireproof, heatproof and waterproof effect of the shell assembly 10 at the outlet passage 14.

[0060] In other embodiments, the waterproof shell 11 can be provided with a fixing column or the like structure to fix the chip module 21. Alternatively, the chip module 21 can be fixed in the waterproof shell 11 by the glue pouring method, which can improve the waterproof effect.

[0061] In some embodiments, the waterproof shell 11 includes a waterproof shell body 111 and a waterproof shell cover 112. The chip module 21 is arranged in the waterproof shell body 111. The waterproof shell cover 112 is arranged on the waterproof shell body 111, which is convenient for disassembly and assembly, and facilitates the installation of the chip module 21 in the waterproof shell 11. The waterproof shell cover 112 and the waterproof shell body 111 are sealingly matched. The waterproof shell cover 112 is provided with a connecting hole 1121. The electric connection line 22 extends out of the waterproof shell 11 through the connecting hole 1121. The waterproof shell body 111 is provided with a slot 1111 to fix the chip module 21.

[0062] In some embodiments, the waterproof shell 11 further includes a waterproof plug 113. Part of the outlet passage 14 is arranged in the waterproof plug 113. The waterproof plug 113 is arranged in the connecting hole 1121. The waterproof plug 113 is configured to be elastically contracted and deformed by being pressed by the waterproof shell cover 112 and the electric connection line 22. By arranging the waterproof plug 113, the waterproof effect of the electric connection line 22 passing through the waterproof shell cover 112 is improved.

[0063] In some embodiments, the waterproof shell 11 further includes a sealing ring 114. The sealing ring 114 is arranged at the joint of the waterproof shell body 111 and the waterproof shell cover 112 to improve the waterproof effect.

[0064] In some embodiments, the fire-resistant and heat-resistant shell 12 includes a fire-resistant and heat-resistant shell body 121 and a fire-resistant and heat-resistant shell cover 122. The waterproof shell 11 is arranged in the fire-resistant and heat-resistant shell body 121. The fire-resistant and heat-resistant shell cover 122 is arranged on the fire-resistant and heat-resistant shell body 121, which is convenient for disassembly and assembly, and facilitates the installation of the waterproof shell 11 in the fire-resistant and heat-resistant shell 12. Part of the outlet passage 14 is arranged in the fire-resistant and heat-resistant shell cover 122.

[0065] In some embodiments, the impact-resistant shell 13 comprises an impact-resistant shell body 131 and an impact-resistant shell cover 132. The fire-resistant and heat-resistant shell 12 is arranged in the impact-resistant shell body 131. The impact-resistant shell cover 132 is arranged on the impact-resistant shell body 131, facilitating the disassembly and assembly of the fire-resistant and heat-resistant shell 12 in the impact-resistant shell 13. The impact-resistant shell cover 132 is fixedly connected with the impact-resistant shell body 131. Part of the wire outlet passage 14 is arranged on the impact-resistant shell cover 132.

[0066] It can be understood that, in some embodiments, the impact-resistant shell 13 further comprises a sealing ring (not shown in the figure) arranged at the joint of the impact-resistant shell cover 132 and the impact-resistant shell body 131 to improve the waterproof effect of the impact-resistant shell 13.

[0067] Referring to Figure 6 In some embodiments, the waterproof shell cover 112 is arranged towards the fire-resistant and heat-resistant shell cover 122 relative to the waterproof shell body 111, and the fire-resistant and heat-resistant shell cover 122 is arranged towards the impact-resistant shell body 131 relative to the fire-resistant and heat-resistant shell body 121, facilitating the electric connecting wire 22 to extend out of the shell assembly 10 through the wire outlet passage 14.

[0068] It can be understood that, in some embodiments, the first partition space 15 is formed at least between the fire-resistant and heat-resistant shell cover 122 and the waterproof shell cover 112 to improve the fireproof and heat insulation effect at the wire outlet passage 14.

[0069] In some embodiments, the impact-resistant shell cover 132 abuts against the fire-resistant and heat-resistant shell cover 122, so that the fire-resistant and heat-resistant shell cover 122 is attached to the fire-resistant and heat-resistant shell body 121 along the arrangement direction.

[0070] The impact-resistant shell cover 132 presses the fire-resistant and heat-resistant shell cover 122 on the fire-resistant and heat-resistant shell body 121, improving the sealing effect between the fire-resistant and heat-resistant shell cover 122 and the fire-resistant and heat-resistant shell body 121, thereby improving the fireproof and heat insulation effect of the fire-resistant and heat-resistant shell 12. Moreover, the structure of the fixed connection between the fire-resistant and heat-resistant shell cover 122 and the fire-resistant and heat-resistant shell body 121 can be omitted, reducing the occupied space of the fire-resistant and heat-resistant shell 12 in the impact-resistant shell 13.

[0071] It can be understood that, in some embodiments, the fire-resistant and heat-resistant shell cover 122 abuts against the waterproof shell cover 112, so that the waterproof shell cover 112 is attached to the waterproof shell body 111 along the arrangement direction.

[0072] The fire-resistant and heat-resistant shell cover 122 bears the force of the impact-resistant shell cover 132, and can press the waterproof shell cover 112 on the waterproof shell body 111, improving the sealing effect between the waterproof shell cover 112 and the waterproof shell body 111, thereby improving the waterproof effect of the waterproof shell 11. Moreover, the structure of the fixed connection between the waterproof shell cover 112 and the waterproof shell body 111 can be omitted, reducing the occupied space of the waterproof shell 11 in the fire-resistant and heat-resistant shell 12.

[0073] In some embodiments, the fire-resistant and heat-resistant shell 12 further comprises a fire-resistant and heat-resistant baffle 123. The fire-resistant and heat-resistant baffle 123 is arranged in the impact-resistant shell body 131. The fire-resistant and heat-resistant baffle 123 is located on the side of the fire-resistant and heat-resistant shell cover 122 facing away from the fire-resistant and heat-resistant shell body 121. The fire-resistant and heat-resistant baffle 123 is spaced apart from the fire-resistant and heat-resistant shell cover 122 to form a second partition space 16. Part of the outlet passage 14 is arranged in the fire-resistant and heat-resistant baffle 123.

[0074] The outlet passage 14 passes through the fire-resistant and heat-resistant shell cover 122 and the impact-resistant shell cover 132. By arranging the fire-resistant and heat-resistant baffle 123 between the fire-resistant and heat-resistant shell cover 122 and the impact-resistant shell cover 132, the heat insulation effect of the shell assembly 10 at the outlet passage 14 is improved. The second partition space 16 is arranged between the fire-resistant and heat-resistant baffle 123 and the fire-resistant and heat-resistant shell cover 122, which reduces the contact between the fire-resistant and heat-resistant baffle 123 and the fire-resistant and heat-resistant shell cover 122, increases the difficulty of heat passing through the fire-resistant and heat-resistant baffle 123 and the fire-resistant and heat-resistant shell cover 122 to the waterproof shell 11, and improves the fireproof and heat insulation effect of the fire-resistant and heat-resistant shell 12.

[0075] It can be understood that, in some embodiments, the second partition space 16 is configured to form a negative pressure compared to the atmospheric pressure, so as to improve the heat insulation effect.

[0076] Referring to Figures 4 to 6 In some embodiments, along the distribution direction of the fire-resistant and heat-resistant shell cover 122 and the fire-resistant and heat-resistant baffle 123, the projection of the part of the fire-resistant and heat-resistant shell cover 122 where the outlet passage 14 is arranged and the projection of the part of the fire-resistant and heat-resistant baffle 123 where the outlet passage 14 is arranged are separated. In other words, the positions of the outlet passage 14 on the fire-resistant and heat-resistant shell cover 122 and the fire-resistant and heat-resistant baffle 123 are staggered.

[0077] The path of the outlet passage 14 from the impact-resistant shell 13 to the waterproof shell 11 through the fire-resistant and heat-resistant shell 12 is curved and zigzag, so as to avoid the hot gas directly passing through the waterproof shell 11, and improve the heat insulation effect of the fire-resistant and heat-resistant shell 12. Moreover, the electric connecting wire 22 is also curved and zigzag in the outlet passage 14, so as to be supported between the fire-resistant and heat-resistant baffle 123 and the fire-resistant and heat-resistant shell cover 122 to maintain the state that the fire-resistant and heat-resistant baffle 123 is spaced apart from the fire-resistant and heat-resistant shell cover 122, thereby improving the fireproof and heat insulation effect of the fire-resistant and heat-resistant shell 12.

[0078] In some embodiments, the impact-resistant shell cover 132 comprises an impact-resistant cover 1321 and a fixing block 1322. The impact-resistant cover 1321 and the fixing block 1322 are connected. The edge of the fire-resistant and heat-resistant baffle 123 is provided with a clearance 1231. The fixing block 1322 passes through the clearance 1231 to abut against the fire-resistant and heat-resistant shell cover 122.

[0079] The impact-resistant cover 1321 can be arranged on the impact-resistant shell body 131 to maintain the sealing effect of the impact-resistant shell 13. By arranging the fixing block 1322 capable of penetrating the fire-resistant heat-resistant baffle 123, the pressing of the impact-resistant shell cover 132 on the fire-resistant heat-resistant shell cover 122 can be maintained, and the spaced arrangement of the fire-resistant heat-resistant baffle 123 and the fire-resistant heat-resistant shell cover 122 can be maintained, which is beneficial to improve the fireproof and heat insulation effect of the fire-resistant heat-resistant shell 12.

[0080] It can be understood that in some embodiments, a plurality of fixing blocks 1322 are arranged in a spaced manner around the inner side wall of the impact-resistant shell body 131 to improve the stability of the connection of the impact-resistant cover 1321.

[0081] In some embodiments, the inner side wall of the impact-resistant shell body 131 is provided with a fixing groove 1311. Part of the fixing block 1322 is clamped in the fixing groove 1311. The fire-resistant heat-resistant baffle 123 abuts against the side of the fixing block 1322 away from the fixing groove 1311 to stop the fixing block 1322 from disengaging from the fixing groove 1311. The impact-resistant cover 1321 and the fixing block 1322 are fixedly connected. The impact-resistant cover 1321 and the fixing block 1322 can be connected by bolts or screws.

[0082] The impact-resistant cover 1321 is longitudinally arranged on the impact-resistant shell body 131, and the fixing block 1322 is transversely inserted into the impact-resistant shell body 131. The impact-resistant cover 1321 can be longitudinally fixedly connected with the fixing block 1322, thereby providing a longitudinal force for the impact-resistant cover 1321, so that the impact-resistant cover 1321 can press the fire-resistant heat-resistant shell 12 longitudinally. Moreover, the fixing block 1322 can be detached from the impact-resistant shell body 131, which can increase the inner diameter of the impact-resistant shell body 131, thereby avoiding hindering the fire-resistant heat-resistant shell 12 from entering the impact-resistant shell body 131, and can reduce the outer diameter of the impact-resistant shell body 131, thereby reducing the occupied space of the impact-resistant shell 13 in the energy storage device 200, and facilitating the adjustment of the arrangement position of the data recording device 100 in the energy storage device 200.

[0083] In other embodiments, the impact-resistant shell cover 132 and the impact-resistant shell body 131 are directly connected by screwing, or the impact-resistant shell cover 132 and the impact-resistant shell body 131 can be connected by a buckle structure.

[0084] In addition, those skilled in the art should understand that the above embodiments are only used to illustrate the present application, and are not used as a limitation to the present application. Any appropriate changes and modifications made to the above embodiments within the spirit and scope of the present application are within the disclosure range of the present application.
