Abstract
Description
Technical Field
[0001] This application relates to the field of energy storage, and in particular to an energy storage device. Background Technology
[0002] Against the backdrop of increased global support for the development of new energy technologies, various energy storage-related technologies have been widely applied. The development of energy storage equipment requires simultaneous consideration of multiple design factors, such as heat dissipation performance, cycle life, and cost, as well as the ease of installation and aesthetics of the equipment. Utility Model Content
[0003] This application provides an energy storage device that improves the installation flatness and appearance of the energy storage device.
[0004] This application provides an energy storage device, including a support frame, a battery module, and an adjustment mechanism. A first recess is provided on the upper side of the support frame. The battery module is disposed on the upper side of the support frame and covers the first recess. The adjustment mechanism includes a base and an adjustment member. The base is disposed on the lower side of the support frame, and the adjustment member connects the base and the support frame. The base supports the support frame via the adjustment member. The adjustment member includes an operating part capable of receiving adjustment operations. The operating part is housed in the first recess, and the adjustment member is configured to drive the support frame to rise and fall relative to the base under the adjustment operation received by the operating part. The adjustment mechanism can adjust the vertical height of the support frame, thereby achieving height adjustment and leveling of the support frame. The operating part can be hidden between the support frame and the battery module, making the appearance of the energy storage device simpler and improving the aesthetics and installation flatness of the energy storage device. The hidden arrangement of the operating part also reduces interference and mutual influence between the operating part and other structures.
[0005] In one or more of the above optional embodiments, the adjusting member and the bracket are threadedly connected, and the adjusting member is rotatably configured relative to the base. The threaded connection method has a simpler structure and a more stable connection, which helps the adjusting member to support the bracket more stably.
[0006] In one or more of the above optional embodiments, the bracket includes a main body and a connecting part. The connecting part is fixedly connected to the main body, a first recess is provided on the upper side of the main body, and the connecting part is threadedly connected to the adjusting member. The main body can be a structural component with a large supporting area and relatively thin thickness, which helps to reduce its weight and improve support stability. The connecting part can be a structural component with a small volume, thicker thickness, and built-in threads, which helps to improve the connection strength and connection stability between the connecting part and the adjusting member. Furthermore, the main body does not necessarily need to be threaded, allowing for more flexible selection of the main body and the connecting part.
[0007] In one or more of the above optional embodiments, the main body includes a first side wall and a first bottom wall, a first recess is formed by the first side wall and the first bottom wall, and the first bottom wall has a first opening; the adjusting member includes an adjusting rod, which extends vertically and passes through the first opening, a portion of the adjusting rod is accommodated in the first recess, and an operating part is disposed in the portion of the adjusting rod accommodated in the first recess; the adjusting rod is rotatably connected to the base and threadedly connected to the connecting part. Rotating the operating part can drive the adjusting rod to rotate synchronously relative to the base, and the connecting part can move up and down along the adjusting rod, thereby driving the main body to move up and down. This simple structure enables the vertical lifting and lowering of the bracket, which helps to reduce costs.
[0008] In one or more of the above optional embodiments, the connecting portion is located on the lower side of the first bottom wall and is fixedly connected to the first bottom wall. This reduces the tensile force between the connecting portion and the first bottom wall, thereby improving the connection strength and stability between them.
[0009] In one or more of the above optional embodiments, the connecting part includes a connecting plate and a connecting nut that are fixedly connected. The connecting plate protrudes radially from the adjusting rod from the connecting nut, and the connecting plate is fixedly connected to the first bottom wall. The connecting nut and the adjusting rod are threaded together. The connecting plate can provide a larger bearing area for the connecting part, reducing the pressure borne per unit area, which helps to reduce the risk of damage to the connecting part and the support.
[0010] In one or more of the above optional embodiments, the adjusting rod includes a rod portion and a support portion. The support portion protrudes radially from the rod portion and is supported on the base and rotatably disposed relative to the base. The support portion can provide a larger support area for the adjusting rod, which is beneficial to improving support stability.
[0011] In one or more of the above optional embodiments, the top of the base is provided with a second recess, and the support portion is rotatably disposed in the second recess. The portion of the base that forms the second recess can limit the support portion along the radial direction of the adjusting rod, restricting the movement of the support portion in the radial direction of the adjusting rod. This reduces the radial misalignment between the support portion and the base, lowers the risk of the support portion falling off the base, and helps improve the stability of the support.
[0012] In one or more of the above optional embodiments, the adjustment mechanism includes a first limiting member, which is fixedly connected to the rod and protrudes radially from the rod. The first limiting member is located between the first bottom wall and the support portion. The first limiting member can limit the maximum downward movement of the bracket relative to the base, reducing the risk of the bracket hitting the ground or other supporting surfaces. At the same time, the first limiting member can also limit the maximum upward movement of the adjusting member relative to the first recess, reducing the risk of interference between the adjusting member and the battery module.
[0013] In one or more of the above optional embodiments, the base has a second opening, through which the adjusting rod passes; the adjusting mechanism includes a second limiting member, which is fixedly connected to the adjusting rod and located on the lower side of the base, and the outer diameter of the second limiting member is larger than the outer diameter of the second opening. The second limiting member can restrict the movement of the base relative to the adjusting rod along the axial direction of the adjusting rod, which helps to reduce the risk of the base falling off the adjusting rod.
[0014] In one or more of the above optional embodiments, the operating part is fixedly connected to the adjusting rod, and the outer diameter of the operating part is larger than the outer diameter of the first opening. The operating part can serve as an upper limiting member of the adjusting member, limiting the maximum upward movement of the bracket relative to the adjusting member, which helps to reduce the risk of the bracket detaching from the adjusting member. The combination of the operating part and the first limiting member can limit the range of movement of the bracket relative to the adjusting member in the vertical direction, which is beneficial for the bracket to rise and fall stably within a suitable range.
[0015] In one or more of the above optional embodiments, the main body includes a second sidewall that surrounds the outer side of the adjustment mechanism portion, and the bottom surface of the base extends downward beyond the second sidewall. The entire bracket is supported by the base, making it less likely to come into contact with the ground or other supporting surfaces, which is beneficial for moisture and water resistance.

Obviously, the described embodiments are some embodiments of this application, but not all embodiments.
[0030] The terms "first," "second," "third," etc., used in the specification, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy. In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.
[0031] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.
[0032] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

For example, if the angle between two directions is 85°-95°, the two directions can be considered perpendicular; if the angle between two directions is 0°-10°, the two directions can be considered parallel.
[0034] The energy storage device of this application is described below with reference to the accompanying drawings.
[0035] Reference Figures 1 to 6 This application provides an energy storage device 1, which includes a support 10 and a first recess 11 on the upper side of the support 10.
[0036] The bracket 10 has a top surface 10a, and a first recess 11 is recessed downward into the top surface 10a. The opening of the first recess 11 faces upward.
[0037] There may be one or more first recesses 11. When there are multiple first recesses 11, they may be distributed at intervals on the outer peripheral edge of the top surface 10a.
[0038] In some embodiments, the energy storage device 1 includes a battery module 20, which is disposed on the upper side of the bracket 10 and covers the first recess 11.
[0039] The battery module 20 can be directly or indirectly supported on the bracket 10, which provides stable support for the battery module 20.
[0040] The battery module 20 can cover the opening of the first recess 11 along the vertical Z direction, thereby covering the first recess 11, so that the first recess 11 is not exposed in the space above the bracket 10.
[0041] There can be one or more battery modules 20. When there are multiple battery modules 20, they can be stacked vertically along the Z-axis.
[0042] The battery module 20 may include multiple batteries, which may be connected in series, in parallel, or in a mixed configuration. A mixed configuration means that there are both series and parallel connections, so that the energy storage device 1 has a larger energy storage voltage.
[0043] In some embodiments, the energy storage device 1 includes an adjustment mechanism 30, which includes a base 31 and an adjustment member 32. The base 31 is located on the lower side of the support 10, and the adjustment member 32 connects the base 31 and the support 10. The base 31 supports the support 10 through the adjustment member 32.
[0044] The weight of the bracket 10 and the battery module 20 can be indirectly applied to the base 31 through the adjustment component 32. The base 31 is used to provide bottom support for the entire energy storage device 1.
[0045] The base 31 can be a foot cup or other structure with a large bottom support surface, which helps to improve the support stability of the base 31.
[0046] The connection methods between the adjusting component 32 and the base 31 include, but are not limited to, rotational connection, sliding connection, and fixed connection.
[0047] The connection methods between the adjusting component 32 and the bracket 10 include, but are not limited to, threaded connection, toothed rack and pinion connection, etc.
[0048] In some embodiments, the adjusting member 32 includes an operating portion 321 capable of receiving an adjusting operation, the operating portion 321 being received in a first recess 11, and the adjusting member 32 being configured to drive the support 10 to rise or fall relative to the base 31 under the adjusting operation received by the operating portion 321.
[0049] The adjustment mechanism 30 can be one or more.
[0050] Optionally, the number of adjustment mechanisms 30 matches the number of first recesses 11, and the adjustment mechanisms 30 and the first recesses 11 are arranged in a one-to-one correspondence, with the operating part 321 of each adjustment mechanism 30 being accommodated in the corresponding first recess 11.
[0051] The base 31 may be located directly below the first recess 11, and a portion of the adjusting member 32 extends downward to the lower side of the bracket 10 and is connected to the base 31.
[0052] In some examples, the operating portion 321 may form at least a portion of the upper end of the adjusting member 32, and the operating portion 321 is the highest part of the adjusting member 32, which facilitates the application of adjustment operations to the operating portion 321. The operating portion 321 is accommodated in the first recess 11, and the adjusting member 32 as a whole does not extend upward beyond the first recess 11, making it less likely to interfere with the battery module 20.
[0053] In other examples, a portion of the adjusting member 32 may also be located above the operating portion 321. This portion of the adjusting member 32 located above the operating portion 321 may be accommodated in the first recess 11 or may be located outside the first recess 11. Exemplarily, the portion of the adjusting member 32 located above the operating portion 321 may protrude upwards from the first recess 11 and the top surface 10a, and be inserted into the positioning structure of the battery module 20, which facilitates the positioning between the battery module 20 and the bracket 10.
[0054] The operating unit 321 can be adjusted manually or automatically from the drive mechanism.
[0055] After the operating unit 321 receives the adjustment operation, it can cause the adjusting member 32 to rotate around the vertical axis or move along the vertical Z, thereby driving the bracket 10 to rise and fall relative to the base 31.
[0056] The adjustment mechanism 30 can adjust the position of the bracket 10 relative to the base 31 along the vertical Z direction. When the base 31 is supported on the ground or other supporting surface, the adjustment mechanism 30 can adjust the height of the bracket 10 along the vertical Z direction, thereby realizing the height adjustment and leveling of the bracket 10.
[0057] The operating unit 321 is entirely located within the first recess 11. The battery module 20 covers the first recess 11, thus concealing the operating unit 321. The operating unit 321 is hidden between the bracket 10 and the battery module 20, resulting in a simpler appearance for the energy storage device 1 and improving its aesthetics and installation flatness. This concealed design also reduces interference and mutual influence between the operating unit 321 and other structures.
[0058] In some embodiments, the adjusting member 32 and the bracket 10 are threadedly connected, and the adjusting member 32 is rotatably disposed relative to the base 31.
[0059] The adjusting member 32 can be inserted into the bracket 10. The adjusting member 32 has external threads, and the bracket 10 has internal threads.
[0060] The adjusting member 32 can be supported on the base 31 and is rotatably mounted relative to the base 31. The adjusting member 32 is fixed in the vertical Z direction relative to the base 31, and when the adjusting member 32 rotates, it will not have a vertical Z displacement relative to the base 31.
[0061] Optionally, a guide structure can be provided at the mating interface between the adjusting member 32 and the base 31 to reduce the frictional force when the adjusting member 32 rotates relative to the base 31, improve the smoothness of the rotation of the adjusting member 32, and reduce the difficulty of adjusting the adjusting member 32. The guide structure can be, for example, a smooth film layer, a ball bearing, etc.
[0062] The adjusting member 32 can rotate around the vertical axis under the adjustment operation received by the operating part 321. When the adjusting member 32 rotates, a relative movement along the vertical Z is generated between the adjusting member 32 and the bracket 10. The bracket 10 can move relative to the base 31 along the vertical Z under the drive of the adjusting member 32, thereby realizing the height adjustment and leveling of the applied 10.
[0063] The adjusting component 32 and the bracket 10 are connected by a threaded connection, which makes the structure simpler and the connection more stable, and helps the adjusting component 32 to support the bracket 10 more stably.
[0064] In some embodiments, the bracket 10 includes a main body 12 and a connecting part 13. The connecting part 13 is fixedly connected to the main body 12, a first recess 11 is provided on the upper side of the main body 12, and the connecting part 13 is threadedly connected to the adjusting member 32.
[0065] The battery module 20 is located on the upper side of the main body 12, and the top surface 10a is the top surface of the main body 12.
[0066] The connecting part 13 can be fixedly connected to the main body 12 by welding, screw connection, riveting or other suitable means.
[0067] The adjusting member 32 can be threaded to the main body 12, or it can only contact the main body 12, or it can be disposed separately from the main body 12.
[0068] Along the vertical Z direction, the thickness of the connecting part 13 can be greater than the thickness of the main body 12, so as to extend the length of the internal thread of the connecting part 13 along the vertical Z direction, which is beneficial to increase the connection area between the connecting part 13 and the adjusting member 32, and improve the connection strength and connection stability between the two.
[0069] The bracket 10 supports the battery module 20 via the main body 12 and is threadedly connected to the adjusting member 32 via the connecting part 13. The main body 12 can be a structural component with a large supporting area and relatively thin thickness, which helps to reduce its weight and improve support stability. The connecting part 13 can be a structural component with a small volume, thicker thickness, and built-in threads, which helps to improve the connection strength and stability between the connecting part 13 and the adjusting member 32. Furthermore, the main body 12 does not necessarily need to be threaded, allowing for more flexible selection of the main body 12 and the connecting part 13.
[0070] In some embodiments, the main body 12 includes a first sidewall 121 and a first bottom wall 122, the first recess 11 is formed by the first sidewall 121 and the first bottom wall 122, and the first bottom wall 122 is provided with a first opening 123.
[0071] There can be one first sidewall 121, in which case the first sidewall 121 can be annular.
[0072] There can also be multiple first sidewalls 121, which are connected in sequence and surround the first recess 11.
[0073] The first bottom wall 122 is connected to the lower end of the first side wall 121, and the opening of the first recess 11 is arranged opposite to the first bottom wall 122 along the vertical Z direction.
[0074] The first opening 123 can penetrate the first bottom wall 122 along the vertical Z direction. The shape of the first opening 123 can be circular, elliptical, rectangular, triangular or other suitable shape.
[0075] In some embodiments, the adjusting member 32 includes an adjusting rod 322 that extends vertically in the Z direction and passes through the first opening 123. A portion of the adjusting rod 322 is received in the first recess 11, and an operating part 321 is provided in the portion of the adjusting rod 322 received in the first recess 11. The adjusting rod 322 is rotatably connected to the base 31 and threadedly connected to the connecting part 13.
[0076] The adjusting rod 322 is rotatably inserted through the first opening 123. A portion of the adjusting rod 322 extends upward through the first opening 123 and is received in the first recess 11, while a portion of the adjusting rod 322 extends downward through the first opening 123 and is connected to the base 31.
[0077] The main body 12 has a first inner circumferential surface that defines a first opening 123. The first inner circumferential surface may be provided with internal threads, and the adjusting rod 322 is threadedly connected to the first inner circumferential surface. Alternatively, the first inner circumferential surface may also be smoothly provided.
[0078] The portion of the adjusting rod 322 extending upward from the first opening 123 can be fully accommodated in the first recess 11, or it can be partially accommodated in the first recess 11 and partially extend upward from the first recess 11.
[0079] In some examples, the operating part 321 may be located at the upper end of the adjusting rod 322, and the upper ends of the operating part 321 and the adjusting rod 322 together form the upper end of the adjusting member 32.
[0080] In other examples, the operating part 321 may also be located below the upper end of the adjusting rod 322, the upper end of which may be accommodated in the first recess 11 or extend upward out of the first recess 11.
[0081] The operating part 321 is fixedly disposed relative to the adjusting rod 322. When the operating part 321 is rotated, it can drive the adjusting rod 322 to rotate synchronously. In some examples, the operating part 321 can be fixedly connected to the adjusting rod 322 by welding, riveting, or other suitable means. In other examples, the operating part 321 can also be form-fitted with the adjusting rod 322. In still other examples, the operating part 321 can also be integrally formed with the adjusting rod 322.
[0082] The operating part 321 can protrude radially from the adjusting rod 322, and the operating part 321 can provide a larger operating area, which is beneficial for applying adjustment operations.
[0083] The adjusting rod 322 can be pressed downward against the base 31 and is rotatably configured relative to the base 31 so as to support the adjusting rod 322 via the base 31.
[0084] The connecting part 13 may be provided with a third opening, which extends through the connecting part 13 vertically in the Z direction. The connecting part 13 has a second inner circumferential surface that defines the third opening. The second inner circumferential surface is provided with an internal thread, and the adjusting rod 322 can pass through the third opening and be threadedly connected to the second inner circumferential surface.
[0085] The connecting part 13 can be fixedly connected to the first bottom wall 122. The connecting part 13 can be provided on the upper side of the first bottom wall 122 or on the lower side of the first bottom wall 122.
[0086] Rotating the operating part 321 can drive the adjusting rod 322 to rotate synchronously relative to the base 31. The connecting part 13 can move up and down along the adjusting rod 322, thereby driving the main body 12 to move up and down. This simple structure can realize the lifting and lowering of the bracket 10 along the vertical Z, which is beneficial to reducing costs.
[0087] In some embodiments, the connecting portion 13 is disposed on the lower side of the first bottom wall 122 and is fixedly connected to the first bottom wall 122.
[0088] The connecting part 13 can be fixedly connected to the first bottom wall 122 by welding, riveting, screwing, bonding or other suitable means.
[0089] The upper surface of the connecting part 13 can be tightly abutted against the lower surface of the first bottom wall 122.
[0090] When the operating part 321 is rotated in the first rotation direction, the connecting part 13 moves upward along the adjusting rod 322, and the connecting part 13 can lift the first bottom wall 122 from the bottom; when the operating part 321 is rotated in the second rotation direction opposite to the first rotation direction, the connecting part 13 moves downward along the adjusting rod 322, and the main body 12 can descend under its own gravity. This reduces the pulling force between the connecting part 13 and the first bottom wall 122, which helps to improve the connection strength and stability between the connecting part 13 and the first bottom wall 122.
[0091] In some embodiments, the connecting part 13 includes a connecting plate 131 and a connecting nut 132 that are fixedly connected. The connecting plate 131 is fixedly connected to the first bottom wall 122, and the connecting nut 132 is threadedly connected to the adjusting rod 322.
[0092] The connecting plate and connecting nut 132 can be fixedly connected by welding, riveting, screwing or other suitable means.
[0093] Along the vertical Z direction, the connecting plate is located between the connecting nut 132 and the first bottom wall 122.
[0094] The third opening extends vertically through the connecting plate 131 and the connecting nut 132 along the Z-axis. The third opening may include the central through hole 1311 of the connecting plate 131 and the central through hole of the connecting nut 132 (not shown in the figure).
[0095] The adjusting rod 322 can be simultaneously inserted into the central through hole 1311 of the connecting plate 131 and the central through hole of the connecting nut 132. The adjusting rod 322 is threadedly connected to the wall of the central through hole of the connecting nut 132. The adjusting rod 322 and the wall of the central through hole 1311 of the connecting plate 131 can be threadedly connected, or they can be only in contact, or they can be separated.
[0096] The connecting plate 131 protrudes radially from the connecting nut 132 along the adjusting rod 322. In the vertical direction Z, the projected area of the connecting plate 131 can be larger than the projected area of the connecting nut 132. The connecting plate 131 can provide a larger bearing area for the connecting part 13, reducing the pressure per unit area and thus helping to reduce the risk of damage to the connecting part 13 and the bracket 10.
[0097] In some embodiments, the adjusting rod 322 includes a rod portion 3221 and a support portion 3222. The support portion 3222 protrudes radially from the rod portion 3221 and is supported on the base 31 and rotatably disposed relative to the base 31.
[0098] The rod 3221 can be a screw, and the screw has an external thread.
[0099] The rod portion 3221 passes through the first opening 123 and the third opening, and the operating part 321 is provided in the part of the rod portion 3221 that is accommodated in the first recess 11.
[0100] The support portion 3222 can be connected to the rod portion 3221 by welding or other suitable means, or it can be integrally formed with the rod portion 3221.
[0101] The support portion 3222 may be arranged around the rod portion 3221. Optionally, the support portion 3222 may be a ring-shaped structure.
[0102] The lower surface of the support part 3222 that contacts the base 31 can be a smooth plane. Ball bearings can also be provided between the support part 3222 and the base 31 to reduce the frictional resistance when the support part 3222 and the base 31 rotate relative to each other.
[0103] The support part 3222 can provide a larger support area for the adjusting rod 322, which is beneficial to improving the stability of the support.
[0104] In some embodiments, the top of the base 31 is provided with a second recess 311, and the support portion 3222 is rotatably disposed in the second recess 311.
[0105] The second recess 311 can be recessed downward into the top surface of the base 31.
[0106] The shape of the second recess 311 can be adapted to the shape of the support portion 3222.
[0107] The support portion 3222 can be entirely accommodated in the second recess 311, or only the lower half of the support portion 3222 can be accommodated in the second recess 311, with the upper half of the support portion 3222 located above the second recess 311.
[0108] The portion of the base 31 used to form the second recess 311 can limit the support 3222 in the radial direction of the adjusting rod 322, restricting the movement of the support 3222 in the radial direction of the adjusting rod 322. This can reduce the radial misalignment between the support 3222 and the base 31, reduce the risk of the support 3222 falling off the base 31, and help improve the stability of the support.
[0109] In some embodiments, the adjustment mechanism 30 includes a first limiting member 33, which is fixedly connected to the rod portion 3221 and protrudes radially from the rod portion 3221. The first limiting member 33 is located between the first bottom wall 122 and the support portion 3222.
[0110] The first limiting member 33 can be fixedly connected to the rod 3221 by welding or other suitable means, or it can be integrally formed with the rod 3221.
[0111] In some examples, the connecting portion 13 is located on the lower side of the first bottom wall 122, and the first limiting member 33 may be located between the connecting portion 13 and the support portion 3222.
[0112] Along the vertical Z direction, the first limiting member 33 and the support portion 3222 can be spaced apart or placed adjacent to each other. The first limiting member 33 and the support portion 3222 can be fixedly connected or integrally formed.
[0113] The outer diameter of the first limiting member 33 may be larger than the outer diameter of the first opening 123 and the outer diameter of the third opening. In the embodiments of this application, "outer diameter" refers to the diameter of the circumscribed circle. For example, the outer diameter of the first limiting member 33 refers to the diameter of the circumscribed circle of the first limiting member 33.
[0114] For example, the first limiting member 33 can be a limiting nut.
[0115] The first limiting member 33 can limit the maximum downward movement of the bracket 10 relative to the base 31, reducing the risk of the bracket 10 hitting the ground or other supporting surfaces. At the same time, the first limiting member 33 can also limit the maximum upward movement of the adjusting member 32 relative to the first recess 11, reducing the risk of interference between the adjusting member 32 and the battery module 20.
[0116] In some embodiments, the base 31 has a second opening 312, through which the adjusting rod 322 passes. The adjusting mechanism 30 includes a second limiting member 34, which is fixedly connected to the adjusting rod 322 and located on the lower side of the base 31. The outer diameter of the second limiting member 34 is larger than the outer diameter of the second opening 312.
[0117] The second opening 312 extends vertically through the base 31 in a Z-direction. The base 31 has a third inner circumferential surface that defines the second opening 312. The adjusting rod 322 can be separated from the third inner circumferential surface to reduce the possibility of the base 31 rotating when the adjusting rod 322 rotates, which helps to reduce friction between the base 31 and the ground or other supporting surfaces. Alternatively, the adjusting rod 322 can also contact the third inner circumferential surface.
[0118] A portion of the adjusting rod 322 extends downward into the second opening 312, and the second limiting member 34 is fixedly connected to this portion of the adjusting rod 322 that extends downward into the second opening 312.
[0119] A third recess 313 may be provided on the lower side of the base 31, and the third recess 313 is recessed upward into the bottom surface 31a of the base 31. The portion of the base 31 that forms the third recess 313 is supported on the ground or other supporting surface. The portion of the adjusting rod 322 that extends downward out of the second opening 312 and the second limiting member 34 can both be accommodated in the third recess 313. The lower end of the adjusting rod 322 is higher than the bottom surface 31a, which helps to reduce the possibility of the lower end of the adjusting rod 322 contacting the ground or other supporting surface and improves the smoothness of the rotation of the adjusting rod 322.
[0120] The second opening 312 can be circular, elliptical, rectangular, triangular, or other suitable shapes.
[0121] The outer diameter of the second limiting member 34 refers to the diameter of the circumscribed circle of the second limiting member 34, and the outer diameter of the second opening 312 refers to the diameter of the circumscribed circle of the second opening 312.
[0122] The second limiting member 34 can restrict the movement of the base 31 relative to the adjusting rod 322 along the axial direction of the adjusting rod 322, which helps to reduce the risk of the base 31 falling off the adjusting rod 322.
[0123] In some embodiments, the operating part 321 is fixedly connected to the adjusting rod 322, and the outer diameter of the operating part 321 is larger than the outer diameter of the first opening 123.
[0124] The operating part 321 can be an operating nut, which is sleeved on the upper end of the adjusting rod 322.
[0125] The outer diameter of the operating part 321 refers to the diameter of the circumscribed circle of the operating part 321, and the outer diameter of the first opening 123 refers to the diameter of the circumscribed circle of the first opening 123.
[0126] The operating part 321 can serve as an upper limiting member of the adjusting member 32, limiting the maximum upward movement of the bracket 10 relative to the adjusting member 32, which helps reduce the risk of the bracket 10 detaching from the adjusting member 32. The combination of the operating part 321 and the first limiting member 33 can limit the range of movement of the bracket 10 relative to the adjusting member 32 in the vertical Z direction, which helps the bracket 10 to rise and fall stably within a suitable range.
[0127] In some embodiments, the main body 12 includes a second sidewall 124 surrounding the outer side of a portion of the adjustment mechanism 30, and the bottom surface 31a of the base 31 extends downward beyond the second sidewall 124.
[0128] The second sidewall 124 can shield a portion of the adjustment mechanism 30 from the outside, which helps to further improve the appearance of the energy storage device 1.
[0129] The bottom surface 31a of the base 31 extends downward beyond the second side wall 124, meaning that when the bracket 10 moves downward relative to the base 31 to the lowest position, the bottom surface 31a still extends downward beyond the second side wall 124.
[0130] The lower end of the second side wall 124 is higher than the bottom surface 31a of the base 31. The bracket 10 is supported by the base 31 as a whole, making it less likely to come into contact with the ground or other supporting surfaces, which is beneficial for moisture and water resistance.
[0131] In some embodiments, the bracket 10 has a guide 14 that extends upward from the main body 12 and is inserted into the battery module 20 adjacent to the bracket 10.
[0132] A guide hole may be provided at the corresponding position on the lower side of the battery module 20 adjacent to the bracket 10, and the guide member 14 may be inserted into the guide hole.
[0133] The guide 14 can guide the assembly of the bracket 10 and the battery module 20, which helps to improve assembly efficiency.
[0134] The energy storage device 1 in this application embodiment can be an energy storage container or an energy storage cabinet, etc.
[0135] The energy storage device described in this application can be used in energy storage power stations, wind power generation systems, solar power generation systems, mobile power systems, or temporary power supply systems, etc. The energy storage device can store electrical energy as needed and output it when appropriate.
[0136] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict.
