[0045] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] Proper storage of batteries in new energy vehicles is crucial for their safety. Typically, battery packs are stored in sealed enclosures, forming the battery pack storage structure. Current technologies design these storage structures specifically for battery packs that utilize liquid cooling plates for heat transfer. For battery packs that use immersion liquid for circulating cooling, existing technologies have not yet developed suitable storage structures.

[0050] Therefore, such as Figures 1-4 As shown, this embodiment provides a battery pack storage structure. This battery pack storage structure is designed for battery packs that employ a circulating immersion liquid cooling heat dissipation method. Specifically, the battery pack storage structure includes a battery pack 200 and a housing 100. The battery pack 200 can dissipate heat from the internal batteries 210 through cyclic immersion liquid cooling. The housing 100 has a housing cavity 150 for housing the battery pack 200. The housing 100 includes a support beam 140, which is fixed in the housing cavity 150. The battery pack 200 is fixed on the support beam 140. The battery pack 200 has a pressure relief hole 220. The battery pack 200, the support beam 140, and the cavity wall of the housing cavity 150 together form a pressure relief gap 500. The housing 100 is provided with a pressure relief channel 1111 that communicates with the outside. The battery pack storage structure is provided with a pressure relief path, which includes the communicating pressure relief hole 220, the pressure relief gap 500, and the pressure relief channel 1111. The gas generated by the pressure relief of the battery 210 is discharged to the outside along the pressure relief path.

[0051] This battery pack storage structure, by providing a receiving cavity 150 within the receiving housing 100, accommodates the battery pack 200, which uses a circulating immersion liquid cooling method for heat dissipation. By fixing a support beam 140 within the receiving cavity 150, the battery pack 200 is fixed to the support beam 140, achieving positioning and fixation of the battery pack 200 relative to the receiving cavity 150. Furthermore, by providing a pressure relief hole 220 within the battery pack 200 and a pressure relief channel 1111 communicating with the outside within the receiving housing 100, the battery pack 200 and the support beam 140 are positioned and fixed. A pressure relief gap 500 is formed between the cavity walls of the receiving cavity 150, giving the battery pack storage structure a pressure relief path. The pressure relief path includes a pressure relief through hole 220, a pressure relief gap 500, and a pressure relief channel 1111, which enables the gas generated by the pressure relief of the battery 210 in the battery pack 200 to be discharged from the pressure relief through hole 220 and then discharged to the outside along the pressure relief path. This meets the pressure relief and discharge requirements of the battery pack 200, which uses a circulating immersion liquid cooling method, and achieves safe storage of the battery pack 200 using a circulating immersion liquid cooling method.

[0052] In addition, in other embodiments, additional channels may be added to the pressure relief through hole 220, pressure relief gap 500 and pressure relief channel 1111 according to actual needs, so that the additional channels together with the pressure relief through hole 220, pressure relief gap 500 and pressure relief channel 1111 form a pressure relief path. This embodiment does not limit the specific extension path and composition structure of the pressure relief path.

[0053] As an optional solution, the housing 100 includes a housing side wall 110, a top plate 120, and a bottom plate 130. The pressure relief channel 1111 is located inside the housing side wall 110. The supporting beam 140 is fixed to the housing side wall 110. The top plate 120 is detachably fixed above the housing side wall 110, and the bottom plate 130 is detachably fixed below the housing side wall 110. The housing side wall 110, the top plate 120, and the bottom plate 130 together form a housing cavity 150. By disassembling the housing 100 into detachable and fixed housing sidewalls 110, top plate 120, and bottom plate 130, the production assembly of the housing 100 and subsequent inspection and maintenance are facilitated. By setting the pressure relief channel 1111 inside the housing sidewall 110 and fixing the supporting beam 140 to the housing sidewall 110, the communication between the pressure relief through hole 220, the pressure relief gap 500, and the pressure relief channel 1111 can be facilitated.

[0054] Specifically, such as Figure 5As shown, the side wall 110 of the enclosure includes a support beam 111 and a connecting member 112. The support beam 111 is a hollow structure, and a first through hole and a second through hole are respectively provided on the support beam 111. The first through hole is used to connect the hollow cavity inside the support beam 111 with the pressure relief gap 500, and the second through hole is used to connect the hollow cavity inside the support beam 111 with the outside. The side wall 110 of the enclosure includes a total of four support beams 111. The four support beams 111 are arranged in pairs, and each pair includes two support beams 111 arranged opposite each other. The extension directions of the two pairs of support beams 111 are horizontal and vertical. The four support beams 111 together form a rectangular structure. The connecting member 112 is arranged between two mutually perpendicular support beams 111. The connecting member 112 is used to connect and fix the two mutually perpendicular support beams 111. By opening a first through hole and a second through hole on the support beam 111 with a hollow cavity, the first through hole connects the hollow cavity and the pressure relief gap 500, and the second through hole connects the hollow cavity to the outside. The first through hole, the hollow cavity, and the second through hole form a pressure relief channel 1111. The structure is simple, easy to form, and reduces the processing difficulty of the pressure relief channel 1111. By using four support beams 111 to form a rectangular structure, and using a connector 112 to connect and fix two mutually perpendicular support beams 111, not only can the welding seal between the two mutually perpendicular support beams 111 be guaranteed, but the structural strength of the box side wall 110 can also be improved.

[0055] It should be noted that, in this embodiment, the adapter 112 is provided with a through hole, which simultaneously connects the hollow cavities in the two connected support beams 111, so that the hollow cavities in the support beams 111 are interconnected, ensuring that the gas generated by the depressurization of the battery in the battery pack 200 can be fully discharged along the depressurization channel 1111.

[0056] In one of the alternative solutions, such as Figure 2 and Figure 5As shown, the housing 100 also includes bolts. The upper and lower surfaces of the housing sidewall 110 are respectively provided with first mounting holes 1112, the top plate 120 is provided with a second mounting hole 121, and the bottom plate 130 is provided with a third mounting hole 131. The bolts are sequentially threaded into the first mounting holes 1112 and the second mounting holes 121, and sequentially threaded into the first mounting holes 1112 and the third mounting holes 131. By providing the first mounting holes 1112 on the upper and lower surfaces of the housing sidewall 110, the second mounting holes 121 on the top plate 120, and the third mounting holes 131 on the bottom plate 130, and by sequentially threading the bolts into the first mounting holes 1112 and the second mounting holes 121, the housing sidewall 110 and the top plate 120 are detachably fixed, and by sequentially threading the bolts into the first mounting holes 1112 and the third mounting holes 131, the housing sidewall 110 and the bottom plate 130 are detachably fixed. It should be noted that, in this embodiment, the side wall 110 of the box includes a support beam 111 and a connector 112. The upper and lower ends of the support beam 111 are provided with first mounting holes 1112, and the upper and lower ends of the connector 112 are provided with fourth mounting holes 1121. The bolt can also be threaded to the fourth mounting hole 1121 and the second mounting hole 121 in sequence, and to the fourth mounting hole 1121 and the third mounting hole 131 in sequence.

[0057] Furthermore, in this embodiment, the upper and lower ends of the side wall 110 of the housing are provided with 32 first mounting holes 1112 and 4 fourth mounting holes 1121 at intervals. The 32 first mounting holes 1112 and 4 fourth mounting holes 1121 form a circle along the end face shape of the side wall 110 of the housing. The top plate 120 is provided with 36 second mounting holes 121 according to the arrangement of the first mounting holes 1112 and the fourth mounting holes 1121. The bottom plate 130 is provided with 36 third mounting holes 131 according to the arrangement of the first mounting holes 1112 and the fourth mounting holes 1121. Each first mounting hole 1112 and each fourth mounting hole 1121 is corresponding to a bolt and a second mounting hole 121 or a third mounting hole 131, so as to further improve the fixing effect between the side wall 110 of the housing, the top plate 120 and the bottom plate 130. In other embodiments, the number of the first mounting holes 1112 and the fourth mounting holes 1121 on the side wall 110 of the housing can be adjusted according to actual needs, and the number of the second mounting holes 121 on the top plate 120 and the third mounting holes 131 on the bottom plate 130 can be adjusted accordingly. This embodiment does not make specific limitations.

[0058] To further improve the sealing effect between the side wall 110 of the enclosure and the top plate 120 and bottom plate 130, such as Figure 2 and Figure 5As shown, grooves 113 are provided on both the upper and lower ends of the side wall 110 of the box. The grooves 113 form a closed loop along the shape of the end face of the side wall 110. The box 100 also includes sealant, which fills the gap between the grooves 113 and the top plate 120 and the bottom plate 130. It should be noted that in this embodiment, the grooves 113 are respectively provided on the upper and lower ends of the support beam 111 and the adapter 112. When the support beam 111 and the adapter 112 together form the side wall 110 of the box, the grooves 113 on the support beam 111 and the adapter 112 together form a closed loop. In addition, in other embodiments, a sealing ring can also be provided in the groove 113 to fill the gap between the groove 113 and the top plate 120 and the bottom plate 130. This embodiment does not make a specific limitation.

[0059] In one of the alternative solutions, such as Figure 6 As shown, the battery pack storage structure also includes a fixing member 300, wherein the sidewall of the fixing member 300 is fixed to the sidewall of the battery pack 200. The fixing member 300 has a first fixing hole 310, and the upper end face of the support beam 140 has a second fixing hole. The battery pack storage structure also includes bolts, which are threaded into the first fixing hole 310 and the second fixing hole in sequence. By fixing the sidewall of the battery pack 200 to the sidewall of the fixing member 300, providing the first fixing hole 310 on the fixing member 300, and providing the second fixing hole on the upper end face of the support beam 140, and using bolts to thread-fix the battery pack 200 to the upper end face of the support beam 140 in sequence, the support and fixation of the battery pack 200 to the upper end face of the support beam 140 is achieved.

[0060] It should be noted that, in this embodiment, as Figure 4 and Figure 5 As shown, a support pad 114 is provided on the lower end face of the side wall 110 of the enclosure. The support pad 114 extends inward relative to the side wall 110 of the enclosure, and the support pad 114 only partially covers the lower end face of the side wall 110 of the enclosure. When the battery pack 200 is fixed together with the support beam 140 by the fastener 300, the lower end face of the battery pack 200 abuts against the upper end face of the support pad 114. The pressure relief hole 220 of the battery pack 200 is provided in the area of ​​the lower end face of the battery pack 200 that is not directly opposite to the support pad 114. A pressure relief gap 500 is formed between the area of ​​the battery pack 200 that is not directly opposite to the support pad 114 and the lower end face and the bottom plate 130.

[0061] In this embodiment, the fastener 300 is provided with two first fixing holes 310 spaced apart. Each first fixing hole 310 corresponds to a second fixing hole and a bolt, thereby further improving the fixing effect between the fastener 300 and the supporting beam 140. In other embodiments, the specific number of first fixing holes 310 can be adjusted according to actual needs, and this embodiment does not impose a specific limitation.

[0062] To further improve the fixing effect between the fastener 300 and the battery pack 200, a reinforcing rib 320 is provided on the upper end surface of the fastener 300. The reinforcing rib 320 does not interfere with the first fixing hole 310, extends upward, and is fixed to the side wall of the battery pack 200. It should be noted that in this embodiment, two reinforcing ribs 320 are provided on the fastener 300 at intervals. In other embodiments, the number of reinforcing ribs 320 can be adjusted arbitrarily according to actual needs, and this embodiment does not impose a specific limitation.

[0063] In one optional embodiment, the battery pack storage structure includes multiple fasteners 300, which are spaced apart along the extension direction of the supporting beam 140, and together secure the battery pack 200 and the supporting beam 140. It should be noted that in this embodiment, the battery pack 200 has supporting beams 140 at both ends along its width direction, and each supporting beam 140 extends along the length direction of the battery pack 200. Two fasteners 300 are spaced apart at both ends of the battery pack 200 along its width direction, and the two fasteners 300 on the same side are fixed to their respective supporting beams 140. In other embodiments, the specific number of fasteners 300 corresponding to each battery pack 200 can be adjusted according to actual needs; this embodiment does not impose a specific limitation.

[0064] As an optional solution, the battery pack 200 also includes an immersion chamber, an inlet connector, and an outlet connector. The immersion chamber has an immersion cavity for storing batteries 210. The immersion chamber has a pressure relief hole 220 that is not connected to the immersion cavity. The immersion cavity has an inlet and an outlet connector. The inlet connector is connected to the inlet connector, and the outlet connector is connected to the outlet connector. By placing the battery 210 in the immersion chamber of the immersion box and opening a pressure relief through hole 220 on the immersion box that is not connected to the immersion chamber, the battery pack 200 can circulate the battery 210 inside for liquid cooling, while the gas generated by the pressure relief of the battery 210 can be normally discharged from the immersion box through the pressure relief through hole 220. By opening an inlet and an outlet on the immersion chamber and connecting the inlet connector to the inlet and the outlet connector to the outlet connector, it is easy for the immersion liquid to enter the immersion chamber through the inlet connector and to be discharged from the immersion chamber through the outlet connector.

[0065] To further improve the integration efficiency of the battery pack storage structure, the battery pack storage structure also includes a connecting pipe 400. At least two battery packs 200 are simultaneously accommodated within the receiving cavity 150. The connecting pipe 400 connects all the circulation immersion channels within the battery packs 200 in parallel. The connecting pipe 400 extends out of the receiving cavity 150 and connects to the output end and output end of the circulation drive device. It should be noted that in this embodiment, the receiving cavity 150 accommodates a total of four battery packs 200. The four battery packs 200 are arranged at intervals along the width direction of the battery packs 200, and the inlet and outlet connectors on the four battery packs 200 are located on both sides of the four battery packs 200 along the length direction. Both ends of each battery pack 200 along the width direction are fixed to the supporting beam 140 by fasteners 300. The connecting pipe 400 includes an inlet connecting pipe and an outlet connecting pipe. The inlet connecting pipe extends along the width direction of the battery pack 200 and connects the inlet connectors of the four battery packs 200 in parallel. The outlet connecting pipe extends along the width direction of the battery pack 200 and connects the outlet connectors of the four battery packs 200 in parallel. The inlet connecting pipe extends out of the receiving cavity 150 and connects to the output end of the circulation drive device. The outlet circulation pipe extends out of the receiving cavity 150 and connects to the input end of the circulation drive device, so as to realize that the circulation drive device simultaneously performs cyclic immersion liquid cooling on the four battery packs 200 connected in parallel. In other embodiments, the size of the receiving cavity 150 can be adjusted according to the specific number of battery packs 200 required. This embodiment does not make a specific limitation.
