[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] The core of the present application is to provide a kind of energy storage cabinet, its battery pack is easy to disassemble.The other core of the present application is to provide a kind of energy storage cabinet battery pack dismounting device applied to the above-mentioned energy storage cabinet, which is easy to disassemble the battery pack in the energy storage cabinet.

[0042] Please refer to Figure 1 And Figure 2The utility model discloses an energy storage cabinet, including cabinet, battery bracket 2 and battery pack 3, the cabinet includes the cabinet body 1 and the cabinet door of openable and closeablely being located at the cabinet body 1, the number of battery bracket 2 and battery pack 3 is at least two respectively, and battery pack 3 and battery bracket 2 correspond one to one, battery pack 3 is located on corresponding battery bracket 2, battery bracket 2 is stacked in the cabinet body 1 along the height direction of cabinet body 1, and the battery bracket 2 from below to top is in turn staggered and arranged along the depth direction of cabinet body 1 (refers to the direction from the end of cabinet body 1 close to the cabinet door to the end away from the cabinet door), so that in any two adjacent battery bracket 2, the battery bracket 2 in the upper part is closer to the cabinet door than the battery bracket 2 in the lower part, so that after battery pack 3 is placed in corresponding battery bracket 2, in any two adjacent battery pack 3, the battery pack 3 in the upper part protrudes from the end of the battery pack 3 in the lower part towards the cabinet door, and additionally, the end of any one battery pack 3 towards the cabinet door protrudes from the corresponding battery bracket 2.

[0043] That is, the energy storage cabinet provided by the utility model embodiment, the battery pack 3 arranged in the energy storage cabinet is arranged in layers along the height direction of the cabinet body 1 and is staggered along the depth direction of the cabinet body 1, so that in any two adjacent battery pack 3 along the height direction of the cabinet body 1, the end of the battery pack 3 in the upper part protrudes from the end of the battery pack 3 in the lower part towards the cabinet door, that is, the end of each battery pack 3 arranged in the energy storage cabinet towards the cabinet door is not flush, and the end of any one battery pack 3 towards the cabinet door protrudes from the corresponding battery bracket 2, so that when the battery pack 3 is disassembled, the end of the battery pack 3 can be lifted from the bottom of the end of the battery pack 3 towards the cabinet door without obstacles, so that the normal pressure of the battery pack 3 on the battery bracket 2 can be reduced, and on this basis, the battery pack 3 can be pulled out of the battery bracket 2, so that the friction can be reduced, and any one battery pack 3 can be conveniently disassembled. Moreover, when the end of the battery pack 3 is lifted from the bottom of the end of the battery pack 3 towards the cabinet door, the battery pack 3 is inclined, so that at least part of the battery pack 3 is not in contact with the battery bracket 2, that is, the contact area of the battery pack 3 and the battery bracket 2 can be reduced, the friction can be reduced, and the wear of the battery pack 3 can be reduced.

[0044] For example, when battery pack 3 is in full contact with battery bracket 2, the normal force exerted by battery pack 3 on battery bracket 2 is N. At this time, the frictional force between battery pack 3 and battery bracket 2 is f = μ × N. When N is large, disassembling battery pack 3 becomes difficult due to the large frictional force. However, when battery pack 3 is lifted towards the bottom of the cabinet door using a forklift, lifting rig, or other available tools, half of the weight of battery pack 3 will be transferred to the forklift, lifting rig, or other available tools. That is, the forklift, lifting rig, or other available tools will bear part of the weight of battery pack 3. At this time, the normal force exerted by battery pack 3 on battery bracket 2 decreases. For example, the normal force exerted by battery pack 3 on battery bracket 2 can be reduced to... This reduces the friction between the battery pack 3 and the battery holder 2, making it easier to pull the battery pack 3 off the battery holder 2.

[0045] It should be noted that in this embodiment, there is no limitation on the distance by which the end of the upper battery pack 3 facing the cabinet door protrudes beyond the end of the lower battery pack 3 facing the cabinet door in any two adjacent battery packs 3, as long as it is convenient to lift the end of the battery pack 3 facing the cabinet door.

[0046] like Figure 2 As shown, in some embodiments, in any two adjacent battery packs 3, the distance by which the end of the upper battery pack 3 facing the cabinet door protrudes beyond the end of the lower battery pack 3 facing the cabinet door is d, and the range of d is 5~12mm.

[0047] It is understandable that if the distance between the protrusion of the upper battery pack 3 towards the cabinet door and the lower battery pack 3 towards the cabinet door is too small, the small contact area will make it difficult to lift the battery pack 3 from its bottom facing the cabinet door. Conversely, if the distance between the protrusion of the upper battery pack 3 towards the cabinet door and the lower battery pack 3 towards the cabinet door is too large, then when there are many battery packs 3, the large offset distance between the uppermost and lowermost battery packs 3 along the depth direction of the cabinet 1 will increase the volume of the cabinet 1, or make it impossible to arrange a large number of battery packs 3 in a cabinet 1 of a specific size. Therefore, in this embodiment, the distance between the protrusion of the upper battery pack 3 towards the cabinet door and the lower battery pack 3 towards the cabinet door is 5~12mm, which is a suitable distance. Furthermore, in some embodiments, in any two adjacent battery packs 3, the end of the upper battery pack 3 facing the cabinet door protrudes by a distance of 10mm from the end of the lower battery pack 3 facing the cabinet door.

[0048] In addition, in order to facilitate the battery pack 3 to be lifted by a proper size towards one end of the cabinet door, in some embodiments, the gap between any two adjacent battery carriers 2 is greater than the preset distance of the battery pack 3, so that the end of the battery pack 3 towards the cabinet door can be lifted by 2-4 mm.

[0049] That is, in the present embodiment, after the battery pack 3 is placed on the corresponding battery carrier 2, the top of the battery pack 3 and the bottom of the first battery carrier 2 above it have a preset distance, so that the end of the battery pack 3 towards the cabinet door can be lifted by 2-4 mm. This distance can prevent the distance between the two adjacent battery carriers 2 from being too large, resulting in the overall height space occupied by all the battery packs 3 being too large, while ensuring that the battery pack 3 can be lifted by a proper distance.

[0050] In addition to the above energy storage cabinet, the utility model also provides a kind of energy storage cabinet battery pack dismounting device applied to the energy storage cabinet disclosed in the above embodiment, which comprises a pad 4 (as shown in Figure 3 And Figure 4 As shown), the pad 4 is used to be inserted between the battery pack 3 and the corresponding battery carrier 2 when dismounting the battery pack 3, and the friction coefficient between the pad 4 and the battery carrier 2 is less than the friction coefficient between the battery pack 3 and the battery carrier 2.

[0051] It can be understood that when the end of the battery pack 3 towards the cabinet door is lifted, the end of the battery pack 3 away from the cabinet door will press the battery carrier 2, and when the battery pack 3 is pulled out, a friction force is generated between the end of the battery pack 3 away from the cabinet door and the battery carrier 2. In the present embodiment, when dismounting the battery pack 3, a pad 4 is inserted between the end of the battery pack 3 away from the cabinet door and the battery carrier 2, so that the pad 4 separates the battery pack 3 from the battery carrier 2, thereby converting the friction force between the battery pack 3 and the battery carrier 2 into the friction force between the pad 4 and the battery carrier 2. Since the friction coefficient between the pad 4 and the battery carrier 2 is less than the friction coefficient between the battery pack 3 and the battery carrier 2, the scheme provided in the present embodiment can reduce the friction force between the battery pack 3 and the battery carrier 2, and avoid direct contact between the battery pack 3 and the battery carrier 2, thereby reducing wear on the battery pack 3. In addition, the design is simple, the pad 4 is easy to process, and the cost of dismounting tools can be reduced. Moreover, the pad 4 is small in structure and easy to carry, and can also be configured as a spare according to the actual situation of the project site.

[0052] It should be noted that the present embodiment does not limit the specific material of the pad 4, as long as the friction coefficient between the pad 4 and the battery carrier 2 is less than the friction coefficient between the battery pack 3 and the battery carrier 2.

[0053] In some embodiments, the pad 4 is made of polytetrafluoroethylene.

[0054] It can be understood that the material of the battery bracket 2 is generally steel, and when the material of the shell of the battery pack 3 is steel, the friction coefficient between steel and steel is 0.15, and when the cushion block 4 is a polytetrafluoroethylene cushion block 4, the friction coefficient between the polytetrafluoroethylene cushion block 4 and steel can be 0.05. Obviously, this material can significantly reduce the friction.

[0055] In addition, in order to further reduce the friction and reduce damage to the cushion block 4, in some embodiments, the end of the bottom of the cushion block 4 away from the cabinet door is provided with an arc-shaped corner 41 for contacting the battery bracket 2.

[0056] It can be understood that when the battery pack 3 is lifted towards the end of the cabinet door, the arc-shaped corner 41 of the cushion block 4 and the battery bracket 2 are in line contact, which can further reduce the friction and reduce the wear of the cushion block 4.

[0057] In addition, in order to facilitate the placement of the cushion block 4 between the battery pack 3 and the battery bracket 2, in some embodiments, the cushion block 4 is a wedge-shaped block.

[0058] It can be understood that the wedge-shaped block is convenient to insert between the battery pack 3 and the battery bracket 2, and is convenient to operate.

[0059] In addition, in order to facilitate the placement of the cushion block 4 between the battery pack 3 and the battery bracket 2, in some embodiments, the energy storage cabinet battery pack dismounting device further comprises a mounting device, the mounting device comprising a fixed plate 5, a movable push plate 6 and a force applying device, the fixed plate 5 being connected with the side of the battery pack 3; the movable push plate 6 being used for contacting the cushion block 4; the force applying device being connected between the fixed plate 5 and the movable push plate 6, and being used for applying force to the movable push plate 6 to push the cushion block 4 into the battery pack 3 and the battery bracket 2.

[0060] That is, when the battery pack 3 needs to be dismounted, the fixed plate 5 is connected with the side of the battery pack 3, and the force applying device is connected between the fixed plate 5 and the movable push plate 6, so that the movable push plate 6 contacts the cushion block 4 away from the side of the battery pack 3 and the battery bracket 2, and then the force applying device is operated to apply force to the movable push plate 6, so that the movable push plate 6 extrudes the cushion block 4 and pushes the cushion block 4 into the battery pack 3 and the battery bracket 2. When the cushion block 4 is pushed into place, the force applying device can also be used to keep the movable push plate 6 generating a pushing force on the cushion block 4, so that the cushion block 4 keeps its position, which is beneficial to pulling out the battery pack 3 while keeping the position of the cushion block 4 between the battery pack 3 and the battery bracket 2.

[0061] It should be noted that the specific structure of the force applying device is not limited in this embodiment, as long as the movable push plate 6 can generate a pushing force on the cushion block 4 when the force applying device is operated.

[0062] In some embodiments, the force applying device comprises a connecting member 7 and a cooperating member 8, the connecting member 7 is disposed between the movable push plate 6 and the fixed plate 5, one end of the connecting member 7 is provided with a limiting part, and the other end is provided with an external thread; the cooperating member 8 is disposed on the side of the fixed plate 5 away from the movable push plate 6 and is in threaded cooperation with the external thread; the limiting part is connected with the movable push plate 6, so that the limiting part drives the connecting member 7 and the movable push plate 6 to move by screwing the cooperating member 8; or the cooperating member 8 is connected with the fixed plate 5, so that the limiting part drives the movable push plate 6 to move by screwing the connecting member 7 while rotating.

[0063] It can be understood that when the limiting part is connected with the movable push plate 6, screwing the cooperating member 8 in the preset direction can make the connecting member 7 drive the movable push plate 6 to move in the direction close to the fixed plate 5, so as to push the cushion block 4 into the battery pack 3 and the battery bracket 2. When the cooperating member 8 is connected with the fixed plate 5, screwing the connecting member 7 can make the limiting part drive the movable push plate 6 to move in the direction close to the fixed plate 5 while rotating, so as to push the cushion block 4 into the battery pack 3 and the battery bracket 2. When the cushion block 4 is installed in place, stopping rotating the cooperating member 8 can make the movable push plate 6 remain unchanged at the position of abutting the cushion block 4, and the thread engagement force between the cooperating member 8 and the external thread is used to ensure that the position of the cushion block 4 between the battery pack 3 and the battery bracket 2 remains unchanged.

[0064] In view of the simplicity of the structure, in some embodiments, the connecting member 7 is a bolt, and the cooperating member 8 is a nut.

[0065] In addition, in some embodiments, the fixed plate 5 is an L-shaped plate, comprising a first plate body and a second plate body, the first plate body is fixed with the battery pack 3, and the second plate body is used to be connected with the movable push plate 6 through the force applying device, and the movable push plate 6 is arranged in parallel with the second plate body.

That is, in this embodiment, the limiting part is used to limit the cushion block 4 by being disposed in the first limiting hole 43 and the second limiting hole.

[0067] In addition, as shown in the drawings, Figure 5 In some embodiments, the end of the cushion block 4 away from the first limiting hole 43 is provided with a U-shaped groove 42 for avoiding interference with other structural members, so as to avoid affecting the insertion of the cushion block 4 between the battery pack 3 and the battery bracket 2.

[0068] In addition, in view of the stability of the movement when the battery pack 3 is pulled out, in some embodiments, the installing device is arranged on both sides of the end of the battery pack 3 away from the cabinet door.

[0069] That is, the two pads 4 are respectively arranged on the two sides of the end of the battery pack 3 away from the cabinet door by the mounting devices on the two sides of the end of the battery pack 3 away from the cabinet door, so that when the battery pack 3 is pulled, the two pads 4 are simultaneously slid relative to the battery bracket 2, and the reliability and stability of the disassembly of the battery pack can be ensured.
