Description

TECHNICAL FIELD

[0001] The utility model relates to energy storage equipment technical field especially relates to a kind of energy storage cabinet. BACKGROUND

[0002] Energy storage cabinet is a kind of equipment specially used for storing and managing energy storage device (such as battery pack), and is widely used in power system, renewable energy consumption, standby power supply and other fields. The traditional energy storage cabinet is usually composed of a cabinet body and several battery packs. These battery packs are generally installed in the cabinet body in a horizontal arrangement, i.e. the long side of the battery pack is perpendicular to the X-axis of the cabinet. However, this arrangement can significantly increase the overall width of the cabinet, thereby limiting its installation and use in narrow spaces.

[0003] To solve this problem, the prior art proposes an improved solution, i.e. placing the battery pack sideways so that the long side of the battery pack is parallel to the X-axis of the cabinet, thereby compressing the Y-axis dimension of the cabinet. This way effectively reduces the width of the cabinet, improves its adaptability, making it more suitable for deployment in space-limited environments. However, this side placement design also brings new challenges: since the battery pack needs to be fixed after placement to ensure stability, in order to facilitate operation, the door panels on both sides of the cabinet body are usually designed as a hinged structure. Although this design improves the convenience of battery pack fixing and placement, it also reduces the overall structural strength of the cabinet body, increases the complexity of the manufacturing process, and leads to an increase in production cost.

[0033] As shown in the figure, in the embodiment, an energy storage cabinet comprises: Figures 1 to 5

[0034] The cabinet body 100 has a containing cavity 110, and the inner wall of the containing cavity 110 is provided with at least one set of first limiting structures 200;

[0035] The battery unit is vertically arranged in the containing cavity 110 and has at least one fixed part 310;

[0036] The floating connection structure 400 is movably connected to the fixed part 310 on one side and detachably connected to the first limiting structure 200 on the other side; through the movement of the floating connection structure 400, the height of the connecting position between the fixed part 310 and the first limiting structure 200 can be adjusted, and the first limiting structure 200 can limit the movement of the battery unit in the containing cavity 110. The design not only effectively saves the width space of the cabinet body 100, so that it can be placed in a narrow environment, but also realizes the absorption of the assembly tolerance between the fixed part 310 and the first limiting structure 200 through the design of the floating connection structure 400, reduces the requirement for accurate alignment, thereby improving the convenience of fixing and placing the battery unit.

[0037] Specifically, as shown in the figure, in the embodiment, the cabinet body 100 is rectangular, has a rectangular containing cavity 110 for accommodating the battery unit. Among them, the cabinet body 100 is provided with a openable and closable front door 101, preferably, the front door 101 is realized by rotation to open and close, ensuring the convenience of disassembling and assembling the battery unit. Figures 1 to 5

[0038] In order to realize the fixation of the battery unit, in the embodiment, the inner wall of the containing cavity 110 is provided with at least one set of first limiting structures 200. The first limiting structure 200 is connected with the battery unit through the floating connection structure 400 and can limit the movement of the battery unit in the containing cavity 110.

[0039] ​​In the embodiment, the first limiting structure 200 is provided with two groups, which are arranged on the opposite left and right inner walls of the accommodating cavity 110. This design can form multiple stress points on a single battery pack 300, ensure the uniformity of stress on both sides when the battery unit is fixed, and also meet the separate fixing of multiple battery packs 300 arranged along the X-axis direction of the cabinet 100. Preferably, the two groups of first limiting structures 200 are above the inner walls, so as to cooperate with the floating connection structure 400 and the fixed part 310 of the battery pack 300 to form a connection and realize the limiting of the battery unit.

[0040] In the embodiment, the length of the first limiting structure 200 is adapted to the width of the accommodating cavity 110, which includes a mounting part 201 and a bent part 202. One end of the mounting part 201 is fixed to the inner wall of the accommodating cavity 110, and the other end extends horizontally along the placement position of the battery unit, for providing support for the floating connection structure 400. The bent part 202 is L-shaped and is connected perpendicularly to the extended end of the mounting part 201. This design enlarges the stress area of the first limiting structure 200, thereby enhancing the strength and stability of the first limiting structure 200.

[0041] In the embodiment, the mounting part 201 of the first limiting structure 200 is provided with a first connecting hole 210, and the first connecting hole 210 penetrates the mounting part 201 in the vertical direction, for cooperating with the fastener and the third connecting hole 420 to realize the fixing of the floating connection structure 400. Preferably, the first connecting hole 210 is circular and is provided with two groups, forming multiple connection points, which further improves the stability of the fixed floating connection structure 400.

[0042] In the embodiment, the battery unit is vertically arranged in the accommodating cavity 110, compared with the lateral arrangement in the prior art, the battery unit can be conveniently disassembled by opening and closing the single front door 101, without the need for additional opening and closing door structures on both sides of the cabinet. On the basis of saving the width space of the cabinet 100, the manufacturing process is simplified and the production cost is reduced.

[0043] To avoid displacement of the battery unit in the accommodating cavity 110 under the action of external force after installation, in the embodiment, the battery unit has at least one fixed part 310 extending in the vertical direction of the accommodating cavity 110. The extension design of the fixed part 310 enables the floating connection structure 400 to move freely within a certain range, thereby absorbing assembly tolerances, ensuring the close cooperation between the battery unit and the limiting structure, and improving the assembly accuracy and reliability. Moreover, after the fixed part 310 is connected with the first limiting structure 200 through the floating connection structure 400, the battery unit can be fixed in the accommodating cavity 110, ensuring the stability and safety of the battery unit during use.

[0044] In this embodiment, the fixing part 310 is an n-shaped lug, which serves as both a connection structure connecting the battery pack 300 to the first limiting structure 200 and a handheld structure for moving the battery pack 300, effectively improving the utilization rate of the structure.

[0045] In this embodiment, the battery unit includes at least two battery packs 300 arranged along the X-axis of the cabinet 100, which improves the power supply of the battery unit. Each battery pack 300 has at least one fixing part 310, and the fixing parts 310 of the two battery packs 300 correspond one-to-one with two first limiting structures 200, and are connected by a floating connection structure 400. This design ensures the stable installation of the multiple battery packs 300 and the overall stability.

[0046] To further improve the stability of fixing multiple battery packs 300, in this embodiment, each battery pack 300 is provided with two fixing parts 310, which are located on the left and right sides of the battery pack 300, respectively. Each fixing part 310 is equipped with a floating connection structure 400, and a second limiting structure 500 is also provided in the receiving cavity 110. The second limiting structure 500 is located between the two battery packs 300 arranged along the X-axis of the cabinet 100 and is detachably connected to the two floating connection structures 400. This design effectively ensures the uniformity of force on the left and right sides of the two battery packs 300 arranged along the X-axis of the cabinet 100, further improving the stability of fixing the battery packs 300.

[0047] In this embodiment, the second limiting structure 500 is in the shape of a rectangular plate, extending vertically along the receiving cavity 110, and has a threaded rod 600 at the top parallel to the fixing part 310. When the floating connection structure 400 is sleeved on the threaded rod 600 and the fixing part 310, the floating connection structure 400 and the battery pack 300 can be fixed by screwing a fastening nut (not shown in the figure) into the threaded rod 600.

[0048] In this embodiment, the battery unit further includes at least two battery packs 300 arranged along the Y-axis of the cabinet 100, each battery pack 300 having at least one fixing part 310. This design further improves the power supply of the battery unit to meet high-power power supply requirements.

[0049] Preferably, in this embodiment, the battery unit includes four battery packs 300 arranged in a matrix, and each battery pack 300 is provided with a fixing part 310 arranged symmetrically from left to right. Each fixing part 310 of the battery packs 300 arranged along the X-axis direction of the cabinet 100 is provided with a floating connection structure 400.

[0050] In this embodiment, each battery pack 300 is provided with a power output panel 320, and the top of the receiving cavity 110 is detachably provided with a power terminal block 120. The power output panel 320 is used to transmit power to the battery pack 300, while the power terminal block 120 is used to manage the power output of multiple battery packs 300 in a unified manner. When the battery cells are vertically arranged in the receiving cavity 110, the power output panel 320 faces the power terminal block 120. This design not only effectively saves the layout length of the wires and reduces production costs, but also simplifies the wire installation process and reduces installation complexity and maintenance difficulty.

[0051] To secure the battery cells, traditional designs typically include a connecting structure fixed to the battery cell for connection with the first limiting structure 200. However, due to assembly tolerances, this type of connecting structure is prone to interference with the first limiting structure 200 during battery cell installation, preventing installation or causing excessive distance between the connecting structure and the first limiting structure 200, thus reducing connection strength. Therefore, in this embodiment, a floating connecting structure 400 is innovatively introduced, forming a movable engagement with the fixing part 310 on the battery pack 300. This absorbs assembly tolerances, reduces the requirement for precise alignment, and thereby improves the convenience of fixing and placing the battery cells.

[0052] In this embodiment, the floating connection structure 400 is arranged horizontally, with one side movably connected to the fixed part 310 and the other side detachably connected to the first limiting structure 200 via fasteners. When the floating connection structure 400 moves along the length of the fixed part 310, the height of the connection position between the fixed part 310 and the first limiting structure 200 can be adjusted. Since the floating connection structure 400 is designed to move on the fixed part 310 and the first limiting structure 200, even if there is a certain assembly tolerance between the fixed part 310 and the first limiting structure 200, the floating connection structure 400 can absorb the assembly tolerance by moving, so that the battery pack 300 can be easily installed in the receiving cavity 110 and form a reliable connection with the first limiting structure 200.

[0053] In this embodiment, the floating connection structure 400 includes a strip-shaped portion 401 and a first protrusion 402 and a second protrusion 403 that are on the same horizontal plane and vertically connected to the strip-shaped portion 401. The first protrusion 402 and the second protrusion 403 are on the same straight line and have a gap between them. This design saves materials and reduces production costs while ensuring the strength of the floating connection structure 400.

[0054] In this embodiment, the strip-shaped portion 401 is provided with a second connecting hole 410 penetrating through itself, and the first protrusion 402 and the second protrusion 403 are each provided with a third connecting hole 420 penetrating through themselves, corresponding one-to-one with the two sets of first connecting holes 210; when the fixing portion 310 is movably inserted into the second connecting hole 410, the third connecting hole 420 is aligned with the first connecting hole 210; the fastener can pass through the third connecting hole 420 and the first connecting hole 210 to fix the floating connection structure 400 onto the first limiting structure 200, thereby limiting the movement of the battery pack 300. This design ensures the ease of assembly of the floating connection structure 400, while also ensuring the stability of the battery pack 300.

[0055] In this embodiment, the second connecting hole 410 is strip-shaped and adapted to the size of the fixing part 310. When the fixing part 310 is movably inserted into the second connecting hole 410, the second connecting hole 410 can restrict the movement of the fixing part 310 in the horizontal plane. This design can achieve initial fixation during the assembly process of the battery pack 300, and also ensure the stability of the battery pack 300 during use, further enhancing the vibration resistance of the system.

[0056] In this embodiment, the third connecting hole 420 is an oblong hole, allowing the fastener to move horizontally within the third connecting hole 420. Furthermore, the movement of the fastener adjusts the gap between the first limiting structure 200 and the fixing part 310. This design enables the floating connecting structure 400 to move not only longitudinally but also laterally to adjust its connection position, further improving the ease of fixing the battery pack 300.

[0057] In this embodiment, the floating connection structure 400 is further provided with a limiting groove 430 penetrating the strip portion 401. The limiting groove 430 is U-shaped and located at the end of the strip portion 401 away from the second connecting hole 410, with the opening of the limiting groove 430 facing away from the second connecting hole 410. When the fixing part 310 of any one of the two adjacent battery packs 300 arranged along the Y-axis of the cabinet 100 is movably inserted into the second connecting hole 410, the limiting groove 430 engages with the fixing part 310 of the other battery pack 300, ensuring that the gap between the two battery packs 300 remains constant. This design ensures that the two adjacent battery packs 300 will not collide under external forces, further improving the safety of the battery packs 300 in use.

[0058] In this embodiment, the fastener includes a threaded rod 600 and a fastening nut (not shown in the figure). The threaded rod 600 can be fixedly inserted into the first connecting hole 210, or it can be detachably inserted into the first connecting hole 210. When the floating connection structure 400 is adjusted to a suitable position, the fastening nut is screwed onto the threaded rod 600 from above the third connecting hole 420 to fix the floating connection structure 400, thereby fixing the battery pack 300.
