[0034] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0035] According to an embodiment of this application, an energy storage device is provided, which will be described below in conjunction with... Figures 1 to 10 Describe in detail the structure and working principle of the energy storage device.

[0036] According to the embodiments of this application, the energy storage device has a length direction and includes a housing 100. The housing 100 includes a first side plate 110, a second side plate 120, a top plate 130, and a panel 140.

[0037] In this embodiment, the first side plate 110 and the second side plate 120 are disposed opposite each other in the length direction. The top plate 130 includes a top plate body, which is disposed above the first side plate 110 and the second side plate 120.

[0038] In one embodiment, the top side of the panel 140 has a first positioning portion and a second positioning portion facing the first side plate 110 and the second side plate 120 respectively. The first positioning portion can abut against the first side plate, and the second positioning portion can abut against the second side plate, so that the panel can rotate around the side where the first positioning portion and the second positioning portion of the panel are located to cover the outside of the first side plate and the second side plate.

[0039] Thus, according to the energy storage device provided in the embodiment of this application, in the housing 100 of the energy storage device, the panel 140 can abut against the first side plate 110 and the second side plate 120 during installation. That is, the first positioning part abuts against the first side plate 110 and the second positioning part abuts against the second side plate 120, thereby achieving the initial positioning of the panel 140 relative to the first side plate 110 and the second side plate 120. Then, the panel 140 is rotated around the side where the first positioning part and the second positioning part are located, so that the other side of the panel 140 moves closer to the first side plate 110 and the second side plate 120, thereby covering the outside of the first side plate 110 and the second side plate 120 with the panel 140.

[0040] Therefore, according to the energy storage device provided in this application embodiment, the panel 140 is an independent structure relative to the first side plate 110 and the second side plate 120, and can be independently disassembled and assembled. Furthermore, it has an effective positioning method during installation, allowing operators to complete the positioning and installation independently, simplifying the installation process and improving installation efficiency. In the embodiment, the first positioning part and the second positioning part can achieve initial positioning of the panel 140 by abutting against the first side plate and the second side plate respectively. This abutting can be edge-to-edge, or it can be achieved through the alignment and cooperation of the protrusion and the opening. In this embodiment, a specific example uses an edge-to-edge setting, which will be explained in detail later.

[0041] In one embodiment, panel 140 covers the outside of the first and second side panels. Panel 140 may be supported by a bottom component and used with removable fasteners (e.g., to attach the panel to other structures of the energy storage device), as will be described in detail later. However, in an example not shown, panel 140 may cover the outside of the first and second side panels using only removable fasteners, such as screws.

[0042] According to the energy storage device provided in the embodiments of this application, the energy storage device may also have a height direction that intersects the length direction, such as being perpendicular to it. As an example, the first positioning part includes a first inclined side, and the second positioning part includes a second inclined side. The first inclined side can abut against the first side plate described above, and the second inclined side can abut against the second side plate, so that the panel 140 can rotate around the side where the first and second positioning parts of the panel are located. The example of the first and second positioning parts described here is that, as mentioned above, the edges abut against each other. This positioning method helps to reduce the complexity of each positioning part.

[0043] In an embodiment, the energy storage device may further include a first support portion 310 and a second support portion 320. The first support portion 310 is disposed on the side of the first side plate 110 facing the panel 140, and the second support portion 320 is disposed on the side of the second side plate 120 facing the panel 140.

[0044] In the embodiment, the first inclined edge 1421 can abut against the first side plate 110, and the second inclined edge 1431 can abut against the second side plate 120, so that the panel 140 can rotate around the side where the first positioning part and the second positioning part of the panel 140 are located (e.g., the upper side of the panel 140) and be supported on the first support part 310 and the second support part 320, thereby covering the outer side of the first side plate and the second side plate.

[0045] In an embodiment, the top plate 130 may further include a limiting part 131, which may be connected to the top plate body. The extending direction of the limiting part 131 may be the length direction, and the limiting part 131 may be spaced apart from the first side plate 110 and the second side plate 120 in the width direction.

[0046] In one embodiment, the upper side of panel 140 can be inserted between the first side plate 110 and the second side plate 120 and the limiting part 131.

[0047] In this embodiment, the limiting part 131, together with the first side plate 110 and the second side plate 120, can be used to limit the panel 140, thereby ensuring that the panel 140 is stably positioned and installed. The panel 140 and the limiting part 131 included in the panel 140 will be described in detail below.

[0048] According to the energy storage device provided in the embodiments of this application, the panel 140 can be formed as a substantially U-shaped plate. Specifically, the panel 140 has a plate body 141, which can be, for example, rectangular in shape. The length direction of the plate body 141 is the length direction of the housing 100 of the energy storage device, and the width direction of the plate body 141 is substantially the height direction of the housing 100.

[0049] In this embodiment, the panel 140 further includes two side plates, namely a first side plate 142 and a second side plate 143, which are respectively disposed on both sides of the panel body 141 in the length direction. The height of the side plates can be the same as the height of the panel body 141 and can be perpendicular to the panel body 141, so that the two side plates and the panel body 141 together form a U-shaped panel.

[0050] In this embodiment, both side plates have two corners on their upper sides, one corner being close to the plate body 141 and the other corner being away from the plate body 141. Specifically, the first inclined edge 1421 is formed at the corner of one side plate away from the plate body 141, and the second inclined edge 1431 is formed at the corner of the other side plate away from the plate body 141.

[0051] In this embodiment, the first side plate 142 may further include a first adjacent side 1422 and a second adjacent side 1423 adjacent to the first inclined side 1421. The first side plate 142 may further include a first rounded corner 1424 located between the first adjacent side 1422 and the first inclined side 1421, and a second rounded corner 1425 located between the second adjacent side 1423 and the second inclined side 1431.

[0052] Thus, according to the energy storage device provided in the embodiments of this application, the first adjacent side 1422 can be, for example, the top edge of the first side plate 142 where the first inclined side 1421 is located, and the second adjacent side 1423 can be, for example, the side of the first side plate 142 where the first inclined side 1421 is located that extends along the height direction. In the embodiments, each of the first adjacent side 1422 and the second adjacent side 1423 is transitioned to the first inclined side 1421 by a rounded corner, which helps to prevent the panel 140 from scratching other parts of the housing 100.

[0053] According to the energy storage device provided in the embodiments of this application, similar to the case of the first inclined side 1421 as described above, the second side plate 143 may also include a third adjacent side and a fourth adjacent side adjacent to the second inclined side 1431. The second side plate 143 may further include a third rounded corner located between the third adjacent side and the second inclined side 1431, and a fourth rounded corner located between the fourth adjacent side and the fourth adjacent side.

[0054] Thus, according to the energy storage device provided in the embodiments of this application, the third adjacent side can be, for example, the top edge of the second side plate 143 where the second inclined side 1431 is located, and the fourth adjacent side can be, for example, the side of the second side plate 143 where the second inclined side 1431 is located that extends along the height direction. In the embodiments, each of the third and fourth adjacent sides is transitioned to the second inclined side 1431 by a rounded corner, which helps to prevent the panel 140 from scratching other parts of the housing 100.

[0055] According to the energy storage device provided in the embodiments of this application, the first adjacent side 1422 and the third adjacent side are both located on the top of the panel 140. The panel 140 can rotate around the first rounded corner 1424 and the third rounded corner and is supported on the first support portion 310 and the second support portion 320.

[0056] According to the energy storage device provided in the embodiments of this application, during the rotational installation of the panel 140, the first rounded corner 1424 and the third rounded corner together serve as fulcrums during the rotation of the panel 140, making the rotation smooth, thereby making the panel 140 rotate smoothly.

[0057] According to the energy storage device provided in the embodiments of this application, the first inclined side 1421 and the second inclined side 1431 can be tilted at an angle of 20°-90° relative to the height direction. This effectively prevents the panel 140 from interfering with other structures during positioning and installation. It facilitates the initial positioning of the panel 140 using the first inclined side 1421 and the second inclined side 1431, while also providing suitable rotational space for the panel 140 to be rotated during installation. As an example, the aforementioned angle can be, for example, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, or 85°. According to the energy storage device provided in the embodiments of this application, the energy storage device may further include a first overlapping portion 150 and a second overlapping portion 160. The first overlapping portion 150 and the second overlapping portion 160 may be respectively disposed on both sides of the panel 140 in the length direction. The first overlapping portion 150 may be used to overlap with the first support portion 310, and the second overlapping portion 160 may be used to overlap with the second support portion 320.

[0058] In this embodiment, a first overlapping portion 150 and a second overlapping portion 160 are provided, which respectively cooperate with the first support portion 310 and the second support portion 320, thereby ensuring the stability of the panel 140 after it is rotated and installed in place.

[0059] As an example, the first overlapping portion 150 and the second overlapping portion 160 may be, for example, pins extending along the length direction of the housing 100, and the first support portion 310 and the second support portion 320 may have plate portions extending in a horizontal plane (that is, a plane jointly determined by the length direction and the width direction) for the corresponding pins to overlap on, thereby providing support for the corresponding pins.

[0060] In this embodiment, the first support portion 310 and the second support portion 320 may have the same structure. Taking the first support portion 310 as an example, in addition to having a plate portion extending in the horizontal plane as described above, the first support portion 310 may also have two plate portions. These three plate portions may be perpendicular to each other, and one of the plate portions may extend in a plane jointly defined by the height direction and the width direction. This plate portion may be connected to the first side plate 110 by a detachable connection method such as bolted connection. Similarly, the second support portion 320 may also be connected to the second side plate 120 in this manner.

[0061] According to the energy storage device provided in the embodiments of this application, the energy storage device may further include an energy storage mechanism, which can be used to store and release electrical energy. The energy storage device may also include a cabinet 200, which is disposed inside the enclosure 100, and the energy storage mechanism is disposed on the cabinet 200.

[0062] In this embodiment, the cabinet 200 can be, for example, an existing cabinet 200, providing multiple accommodating spaces for placing energy storage devices. Each accommodating space can be defined by two slide rails 210 arranged opposite each other along the length direction described above. The two sides of the energy storage device can respectively cooperate with the two slide rails 210 to place the energy storage device into the accommodating space between the two slide rails 210. The slide rail structure here is also an existing structure, and is only briefly described here.

[0063] Furthermore, as an example, an energy storage device can be, for instance, a battery pack, such as a lithium-ion battery pack.

[0064] In an embodiment, the energy storage device may further include a spacer 400 disposed between the cabinet 200 and the top plate 130. The spacer 400 can be clamped by the cabinet 200 and the top plate 130 so that the middle part of the top plate 130 protrudes, which can prevent water from accumulating on the outside of the top plate 130 and facilitate drainage of the top plate 130.

[0065] In other words, the energy storage device can lift the top plate 130 of the housing 100 by adding spacers 400 such as rigid foam inside, so that the top plate 130 forms an approximate arc shape. After properly adjusting the thickness of the rigid foam, this arc shape is not even easy for people to observe, but it can still prevent water from accumulating on the outside of the top plate 130, thus cleverly and cost-effectively achieving top drainage.

[0066] According to the energy storage device provided in the embodiments of this application, as described above, a polycarbonate layer 211 is provided between the slide structure and the energy storage mechanism. For example, the polycarbonate layer 211 can be provided on the slide structure, so that no marks are generated when the battery pack casing rubs against the slide 210 (e.g., a guide rail), thus avoiding mutual scratches between the battery pack casing and the slide 210. As an example, the slide structure can be, for example, a U-shaped structure, which can extend along the width direction as described above, and define a groove extending along the width direction through its U-shaped structure. A part of the battery pack is inserted into the groove and can slide relative to the slide 210 along the extension direction of the groove, that is, the width direction as described above.

[0067] Therefore, as an example, the polycarbonate layer 211 can be bonded, for example, to the two opposing inner walls of the groove and the bottom wall between the two inner walls, thereby achieving all-around scratch protection.

[0068] According to the energy storage device provided in the embodiments of this application, the energy storage device may further include a first fastener and a second fastener. The panel 140 and the cabinet 200 may be detachably connected via the first fastener, and the panel 140 and the cabinet 200 may be detachably connected via the second fastener.

[0069] As an example, both the first and second fasteners can be screws. The front side of the cabinet 200 can have two rod-shaped protrusions 220, each with threaded holes for screws to pass through. After the panel 140 is rotated into position, the positions of the two through holes on the panel 140 can correspond to the positions of the two threaded holes, allowing two screws to pass through the two through holes and be screwed into the two threaded holes, thus connecting the panel 140 to the cabinet 200. Furthermore, in this embodiment, both the first and second fasteners can also be, for example, matching bolts and nuts.

[0070] The above are merely preferred embodiments of this application and do not limit the scope of protection of this application. Any equivalent structural transformations made based on the innovative concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
