[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the fixed scope of the present utility model.

[0036] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0037] This utility model discloses an energy storage device, which includes a cabin 10, in which a battery compartment 11 is disposed; a frame 20, which is fixedly connected to the inner wall of the battery compartment 11, and the frame 20 includes a first fixing rod 21 and a second fixing rod 22, both of which extend along a first direction X and are spaced apart along a second direction Y, where the first direction X is the width direction of the cabin 10 and the second direction Y is the length direction of the cabin 10; and a battery pack 30, which is disposed between the first fixing rod 21 and the second fixing rod 22 and is detachably connected to the first fixing rod 21 and the second fixing rod 22.

[0038] This utility model discloses an energy storage device that can serve as a power source to provide electrical energy to electrical equipment. For example, the energy storage device can be installed on a vehicle body 90 to form a mobile energy storage vehicle, which offers advantages such as safety, convenience, and environmental friendliness. Of course, in this utility model embodiment, no excessive restrictions are placed on the specific application of the energy storage device; any application is permissible.

[0039] The following description will use the energy storage device used in a mobile energy storage vehicle as an example to illustrate this utility model. The mobile energy storage vehicle includes a vehicle body 90 and an energy storage device, which is mounted on the vehicle body 90.

[0040] The energy storage device disclosed in this embodiment of the present invention includes a cabin 10, which can be a cuboid structure, a cube structure, or other irregular structure. In this embodiment of the present invention, the specific structure of the cabin 10 is not limited; in practical applications, technicians can set the specific structure of the cabin 10 as needed.

[0041] The following description uses a cuboid structure for the cabin 10 as an example to illustrate this utility model. The width direction of the cabin 10 is the first direction X, meaning the width direction of the vehicle body 90 is the first direction X. The length direction of the cabin 10 is the second direction Y, meaning the length direction of the vehicle body 90 is the second direction Y.

[0042] Along the second direction Y, the cabin 10 contains, in sequence, a liquid cooling cabin, a battery cabin 11, an equipment cabin, and a charging cabin. Adjacent cabins are separated by partitions. The battery cabin 11 contains multiple battery clusters, all vertically arranged and spaced apart. Each battery cluster includes, from bottom to top, multiple battery packs 30, a main control box, and a converter. Due to the significant weight of the battery packs 30, placing them at the bottom of the battery cluster lowers the center of gravity, increasing the safety and stability of the energy storage device. The battery packs 30 store electrical energy. The main control box, as the core management unit of the battery cluster, can collect parameters such as voltage, current, temperature, and insulation resistance of the battery cluster in real time. The converter converts the direct current (DC) in the battery packs 30 into alternating current (AC) for use by electrical equipment.

[0043] like Figure 1 As shown, the energy storage device disclosed in this embodiment of the present invention also includes a frame 20, which is fixedly connected to the inner wall of the battery compartment 11. "Fixedly connected" means that the frame 20 does not move relative to the inner wall of the battery compartment 11.

[0044] For example, two frames 20 are provided inside the battery compartment 11. The two frames 20 are connected as a whole by connectors to improve the overall seismic resistance of the frames 20. Each frame 20 is detachably connected to the bottom wall of the battery compartment 11 by multiple bolts, the top of each frame 20 is welded to the top wall of the battery compartment 11 by square tubing, and the middle position of the frame 20 is detachably connected to the partition of the battery compartment 11 by connectors. With the above arrangement, the frame 20 is fixedly connected to the inner wall of the battery compartment 11, so that the frame 20 is fixed relative to the inner wall of the battery compartment 11.

[0045] Of course, the above are only individual examples of specific ways in which the frame 20 is fixedly connected to the inner wall of the battery compartment 11, and are not intended to limit the present invention. In practical applications, technicians can set the fixed connection method between the frame 20 and the inner wall of the battery compartment 11 as needed.

[0046] like Figure 1 As shown, the frame 10 includes a first fixing rod 21 and a second fixing rod 22 extending along a first direction X and spaced apart along a second direction Y. That is, both the first fixing rod 21 and the second fixing rod 22 extend along the width direction of the frame 10, and are spaced apart along the length direction of the frame 10. A battery pack 30 is disposed between the first fixing rod 21 and the second fixing rod 22, and is detachably connected to the first fixing rod 21 and the second fixing rod 22 to fix the battery pack 30, preventing it from shifting and thus improving the safety and reliability of the energy storage device.

[0047] For example, the battery pack 30 is snapped onto the first fixing rod 21 and the second fixing rod 22, and / or the battery pack 30 is fixedly connected to the first fixing rod 21 and the second fixing rod 22 by bolts. Of course, in this embodiment of the present invention, there are no excessive restrictions on the specific manner in which the battery pack 30 is detachably connected to the first fixing rod 21 and the second fixing rod 22. In actual applications, technicians can set it as needed.

[0048] In some embodiments, such as Figure 2 As shown, along the second direction Y, the battery pack 30 has a first sidewall 31 and a second sidewall 32 disposed opposite to each other; a first snap-fit ​​member 311 is provided on the first sidewall 31 and the second sidewall 32 respectively, and a second snap-fit ​​member 211 is provided on the first fixing rod 21 and the second fixing rod 22 respectively, and the first snap-fit ​​member 311 is snapped into the second snap-fit ​​member 211.

[0049] like Figure 2 As shown, the battery pack 30 in this embodiment of the present invention has a cuboid structure. The battery pack 30 has a first sidewall 31 and a second sidewall 32 arranged opposite to each other along the second direction Y, and a third sidewall 33 and a fourth sidewall 34 arranged opposite to each other along the first direction X.

[0050] Of course, the above are merely individual examples of the specific structure of the battery pack 30 and are not intended to limit the present invention. In practical applications, those skilled in the art can customize the specific structure of the battery pack 30 as needed. The following will use a cuboid structure as an example to illustrate the present invention.

[0051] like Figure 2 As shown, first latching members 311 are respectively provided on the first sidewall 31 and the second sidewall 32. It can be understood that at least one first latching member 311 is provided on the first sidewall 31 and at least one first latching member 311 is provided on the second sidewall 32. Second latching members 211 are respectively provided on the first fixing rod 21 and the second fixing rod 22. It can be understood that at least one second latching member 211 is provided on the first fixing rod 21 and at least one second latching member 211 is provided on the second fixing rod 22.

[0052] Each first connector 311 is snapped into a second connector 211 to limit the second direction Y and height direction of the battery pack 30 through the first connector 311 and the second connector 211, so as to prevent the battery pack 30 from shifting in the second direction Y and height direction, thereby improving the safety and reliability of the energy storage device.

[0053] For example, the first latching member 311 can be a wedge-shaped block, and the second latching member 211 can be a wedge-shaped groove. Alternatively, the first latching member 311 can be a wedge-shaped groove, and the second latching member 211 can be a wedge-shaped block. Of course, the above are only individual examples of the specific structures of the first latching member 311 and the second latching member 211, and are not intended to limit the present invention. In practical applications, those skilled in the art can set the specific structures of the first latching member 311 and the second latching member 211 as needed.

[0054] In some embodiments, such as Figure 2 As shown, the first snap-fit ​​member 311 includes at least two, and the at least two first snap-fit ​​members 311 are spaced apart along the first direction X on the first side wall 31 or the second side wall 32; the second snap-fit ​​member 211 includes at least two, and the at least two second snap-fit ​​members 211 are spaced apart along the first direction X on the first fixing rod 21 or the second fixing rod 22, and each first snap-fit ​​member 311 snaps into a second snap-fit ​​member 211.

[0055] like Figure 2 As shown in this embodiment of the invention, at least two first snap-fit ​​members 311 are provided on the first sidewall 31, and the at least two first snap-fit ​​members 311 are spaced apart along the first direction X. At least two second snap-fit ​​members 211 are provided on the first fixing rod 21, and the at least two second snap-fit ​​members 211 are spaced apart along the first direction X. Each first snap-fit ​​member 311 snaps into one second snap-fit ​​member 211, so as to detachably connect the first sidewall 31 to the first fixing rod 21.

[0056] Furthermore, at least two first snap-fit ​​members 311 are provided on the second sidewall 32, and the at least two first snap-fit ​​members 311 are spaced apart along the first direction X. At least two second snap-fit ​​members 211 are provided on the second fixing rod 22, and the at least two second snap-fit ​​members 211 are spaced apart along the first direction X. Each first snap-fit ​​member 311 snaps into a second snap-fit ​​member 211 to detachably connect the second sidewall 32 to the second fixing rod 22.

[0057] In this embodiment of the present invention, the first sidewall 31 is detachably connected to the first fixing rod 21 by at least two first snap-fit ​​pieces 311 and at least two second snap-fit ​​pieces 211, and the second sidewall 32 is detachably connected to the second fixing rod 22 by at least two first snap-fit ​​pieces 311 and at least two second snap-fit ​​pieces 211, so as to further improve the reliability of the connection between the battery pack 30 and the first fixing rod 21 and the second fixing rod 22, thereby further improving the safety and reliability of the energy storage device.

[0058] It should be noted that, in this embodiment of the present invention, the number of first latching members 311 provided on the first sidewall 31 is the same as the number of second latching members 211 provided on the first fixing rod 21. Furthermore, the number of first latching members 311 provided on the second sidewall 32 is the same as the number of second latching members 211 provided on the second fixing rod 22.

[0059] For example, two first snap-fit ​​members 311 are provided on the first sidewall 31, and two second snap-fit ​​members 211 are provided on the first fixing rod 21. Two first snap-fit ​​members 311 are provided on the second sidewall 32, and two second snap-fit ​​members 211 are provided on the second fixing rod 22.

[0060] In some embodiments, the first latching member 311 includes a protrusion and the second latching member 211 includes a groove; or, the first latching member 311 includes a groove and the second latching member 211 includes a protrusion.

[0061] It is understandable that when the first latching member 311 is a protrusion, the second latching member 211 is a recess. When the first latching member 311 is a recess, the second latching member 211 is a protrusion.

[0062] For example, the first latching member 311 can be a wedge-shaped block, and the second latching member 211 can be a wedge-shaped groove. Alternatively, the first latching member 311 can be a wedge-shaped groove, and the second latching member 211 can be a wedge-shaped block.

[0063] In this embodiment of the invention, the first snap-fit ​​member 311 is configured as either a protrusion or a groove, and the second snap-fit ​​member 211 is configured as either a protrusion or a groove. This simplifies the structure of the first snap-fit ​​member 311 and the second snap-fit ​​member 211, thereby facilitating the fabrication of the energy storage device and the installation of the battery pack 30.

[0064] In some embodiments, such as Figure 2 As shown, guide grooves 312 are respectively provided on the first sidewall 31 and the second sidewall 32, and guide members 212 are respectively provided on the first fixing rod 21 and the second fixing rod 22. Alternatively, guide members 212 are respectively provided on the first sidewall 31 and the second sidewall 32, and guide grooves 312 are respectively provided on the first fixing rod 21 and the second fixing rod 22. Both the guide grooves 312 and the guide members 212 extend along the first direction X, and the guide members 212 are slidably connected to the guide grooves 312.

[0065] like Figure 2 As shown in the embodiment of this utility model, guide grooves 312 are respectively provided on the first sidewall 31 and the second sidewall 32. The guide grooves 312 extend along the first direction X. Guide members 212 are respectively provided on the first fixed rod 21 and the second fixed rod 22. The guide members 212 extend along the first direction X. Each guide member 212 is slidably connected in a guide groove 312.

[0066] Alternatively, guide members 212 are respectively provided on the first sidewall 31 and the second sidewall 32, the guide members 212 extend along the first direction X, and guide grooves 312 are respectively provided on the first fixed rod 21 and the second fixed rod 22, the guide grooves 312 extend along the first direction X, and each guide member 212 is slidably connected in a guide groove 312.

[0067] With the above-mentioned configuration, during the installation of the battery pack 30, the installation position of the battery pack 30 can be corrected by the conductive groove 312 and the guide 212, so as to improve the installation accuracy of the battery pack 30, avoid the battery pack 30 from shifting, and improve the safety and reliability of the energy storage device.

[0068] In some embodiments, along the first direction X, the battery pack 30 has a third sidewall 33 and a fourth sidewall 34 disposed opposite to each other. The energy storage device further includes: a first fixing member 40, which is fixedly connected to a first fixing rod 21; a second fixing member 50, which is fixedly connected to a second fixing rod 22, and the first fixing member 40 and the second fixing member 50 are disposed opposite to each other along the second direction Y; and two third fixing members 60, which are disposed at intervals along the second direction Y on the third sidewall 33. The first fixing member 40 is snapped into one of the third fixing members 60, and the second fixing member 50 is snapped into the other third fixing member 60.

[0069] like Figure 3 As shown in the embodiment of this utility model, a first fixing member 40 is fixedly connected to the first fixing rod 21, and a second fixing member 50 is fixedly connected to the second fixing rod 22. The first fixing member 40 and the second fixing member 50 are arranged at intervals relative to each other along the second direction Y. That is, along the length direction of the cabin 10, the first fixing member 40 and the second fixing member 50 are arranged at intervals relative to each other.

[0070] It should be noted that, in this embodiment of the present invention, the first fixing member 40 is fixedly connected to the first fixing rod 21, and the second fixing member 50 is fixedly connected to the second fixing rod 22. Here, "fixedly connected" means that the first fixing member 40 does not move relative to the first fixing rod 21, and the second fixing member 50 does not move relative to the second fixing rod 22.

[0071] For example, the first fixing member 40 is integrally formed with the first fixing rod 21, and the second fixing member 50 is integrally formed with the second fixing rod 22. Alternatively, the first fixing member 40 is fixedly connected to the first fixing rod 21 by bolts, and the second fixing member 50 is fixedly connected to the second fixing rod 22 by bolts.

[0072] Along the second direction Y, two third fixing members 60 are spaced apart on the third sidewall 33. One third fixing member 60 is snapped into connection with the first fixing member 40, and the other third fixing member 60 is snapped into connection with the second fixing member 50. The first fixing member 40 and one of the third fixing members 60, as well as the second fixing member 50 and the other third fixing member 60, limit the first direction X of the battery pack 30, preventing the battery pack 30 from shifting in the first direction X, thereby improving the safety and reliability of the energy storage device.

[0073] For example, the first fixing member 40 can be a protrusion, and the third fixing member 60 that cooperates with the first fixing member 40 can be a groove. Alternatively, the first fixing member 40 can be a groove, and the third fixing member 60 that cooperates with the first fixing member 40 can be a protrusion. Of course, the above are only individual examples of the specific structures of the first fixing member 40 and the third fixing member 60 that cooperates with the first fixing member 40, and are not intended to limit the present utility model.

[0074] It should be noted that the structures of the second fastener 50 and the third fastener 60 that cooperate with the second fastener 50 are similar to the structures of the first fastener 40 and the third fastener 60 that cooperate with the first fastener 40 described above. Further details will not be provided here.

[0075] In some embodiments, such as Figure 4 As shown, the energy storage device further includes a fourth fixing member 70, which is detachably connected to the first fixing rod 21. Along the first direction X, the fourth fixing member 70 and the first fixing member 40 are spaced apart. A fifth fixing member 80 is detachably connected to the second fixing rod 22. Along the first direction X, the fifth fixing member 80 and the second fixing member 50 are spaced apart, and along the second direction Y, the fifth fixing member 80 and the fourth fixing member 70 are spaced apart relative to each other. A fourth sidewall 34 is detachably connected to the fourth fixing member 70 and the fifth fixing member 80.

[0076] For example, the fourth fixing member 70 is detachably connected to the first fixing rod 21 by bolts, and the fifth fixing member 80 is detachably connected to the second fixing rod 22 by bolts. Of course, in this embodiment of the present invention, there are no excessive restrictions on the specific manner in which the fourth fixing member 70 is detachably connected to the first fixing rod 21, and the specific manner in which the fifth fixing member 80 is detachably connected to the second fixing rod 22. In practical applications, technicians can set them as needed.

[0077] like Figure 4As shown, the fourth fixing member 70 is detachably connected to the first fixing rod 21, and the fourth fixing member 70 and the first fixing member 40 are spaced apart along the first direction X. The fifth fixing member 80 is detachably connected to the second fixing rod 22, and the fifth fixing member 80 and the second fixing member 50 are spaced apart along the first direction X. Furthermore, along the second direction Y, the fifth fixing member 80 and the fourth fixing member 70 are spaced apart relative to each other. The fourth sidewall 34 of the battery pack 30 is detachably connected to the fourth fixing member 70 and the fifth fixing member 80 by bolts to limit the battery pack 30 in the first direction X, preventing the battery pack 30 from shifting in the first direction X, thereby improving the safety and reliability of the energy storage device.

[0078] As an optional implementation, one of the first fixing member 40 and the third fixing member 60 is provided with a first guide hole 61, and the other of the first fixing member 40 and the third fixing member 60 is provided with a first guide pin 41, which is inserted into the first guide hole 61; and / or, one of the second fixing member 50 and the other third fixing member 60 is provided with a second guide hole 62, and the other of the second fixing member 50 and the other third fixing member 60 is provided with a second guide pin 51, which is inserted into the second guide hole 62.

[0079] In this embodiment of the invention, a first guide hole 61 can be provided on the first fixing member 40, and a first guide pin 41 can be provided on a third fixing member 60. The first guide pin 41 is inserted into the first guide hole 61 to snap-fit ​​the first fixing member 40 and the third fixing member 60 together. Alternatively, a first guide pin 41 can be provided on the first fixing member 40, and a first guide hole 61 can be provided on a third fixing member 60. The first guide pin 41 is inserted into the first guide hole 61 to snap-fit ​​the first fixing member 40 and the third fixing member 60 together.

[0080] In this embodiment of the invention, a second guide hole 62 can be provided on the second fixing member 50, and a second guide pin 51 can be provided on another third fixing member 60. The second guide pin 51 is inserted into the second guide hole 62 to snap-fit ​​the second fixing member 50 and the other third fixing member 60. Alternatively, a second guide pin 51 can be provided on the second fixing member 50, and a second guide hole 62 can be provided on another third fixing member 60.
