Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to a battery frame device, a battery cabinet, and a battery energy storage system. Background Technology

[0002] During the hoisting process, the battery clusters in existing battery cabinets generally lack lateral support structures, resulting in insufficient overall lifting strength. This insufficient strength manifests itself in the fact that when multiple battery clusters are hoisted as a whole, mutual displacement and misalignment between battery clusters are very likely to occur, ultimately affecting the arrangement accuracy and assembly effect of the battery clusters in the battery cabinet.

[0003] In the prior art, although adding a horizontal support structure directly to the main body of the battery frame of the battery cluster can enhance the lifting strength, the disassembly and assembly of the horizontal support structure is complicated and cumbersome, and its structure hinders the independent lifting of a single battery cluster and subsequent maintenance operations. Utility Model Content

[0004] In view of this, this application provides a battery frame device, a battery cabinet, and a battery energy storage system to solve the problems of complex disassembly and assembly operations and obstacles to the independent lifting of individual battery clusters when directly adding a lateral support structure to the main body of the battery frame of the battery cluster.

[0005] In a first aspect, this application provides a battery frame device, including a plurality of battery frame bodies arranged along a first direction; each battery frame body includes a top frame and a reinforcing beam, wherein the reinforcing beam is fixedly disposed on the top frame and its axial direction is parallel to the first direction; wherein, for any two adjacent reinforcing beams, one end of one of them is provided with a slot, the slot passing through the reinforcing beam along a second direction, and the other end of the other is provided with a snap-fit ​​protrusion, the snap-fit ​​protrusion being adapted to enter the slot along the second direction and form a snap-fit ​​engagement with the slot.

[0006] Beneficial effects: Reinforcing beams are arranged on the top frame, with adjacent beams connected by slots and engaging protrusions, improving overall lifting strength. When multiple battery frame bodies are lifted as a whole, mutual displacement and misalignment between them are less likely, ensuring the accuracy of battery cluster placement and assembly within the battery cabinet. Furthermore, since the reinforcing beams are installed on the top frame, they do not need to be disassembled after lifting, eliminating the need for beam removal and simplifying the overall lifting process. Additionally, the engaging protrusions are designed to enter the slots in a second direction, facilitating the separation of individual battery frame bodies and enabling independent lifting and subsequent maintenance of individual battery clusters.

[0007] In one alternative embodiment, the slot includes an inner cavity and a latch, the latch communicating with the inner cavity, and the width W1 of the latch being smaller than the width W2 of the inner cavity; the shape of the latching protrusion is adapted to the shape of the slot.

[0008] Beneficial effects: The width of the slot is smaller than the width of the inner cavity, which restricts the horizontal displacement of the locking protrusion. When multiple battery frame bodies are lifted as a whole, it makes it less likely for adjacent battery frame bodies to be misaligned in the horizontal direction, thereby ensuring the arrangement accuracy and assembly effect of the battery clusters in the battery cabinet.

[0009] In one alternative embodiment, the slot is one of a dovetail groove, a C-shaped groove, or a circular arc groove.

[0010] Beneficial effects: The card slot is designed with the above structure, which is simple, strong and low in cost.

[0011] In one alternative embodiment, the top frame includes a first beam extending in a direction parallel to the first direction, and the reinforcing beam is connected to the first beam.

[0012] Beneficial effect: The reinforcing beam is installed on the first beam, and the two work together to further enhance the overall strength of the top frame.

[0013] In one alternative embodiment, a connector is further included, which securely connects the top frame and the reinforcing beam.

[0014] Beneficial effects: The connecting parts make it easy to fix the reinforcing beam to the top frame, and the reinforcing beam can be separated from the top frame by disassembling the connecting parts. The installation and disassembly of the reinforcing beam is simple and convenient.

[0015] In one optional embodiment, the top frame further includes a second beam, which is perpendicular to the first beam. There are two of each of the first and second beams, and the two first beams and two second beams cooperate to enclose the top frame, which forms a rectangular frame structure.

[0016] The connector is used to fix the first beam to the reinforcing beam.

[0017] And / or, the connector securely connects the second beam to the reinforcing beam.

[0018] Beneficial effects: The first beam and the second beam work together to form the top frame, and the reinforcing beam is fixed to the first beam and / or the second beam through connectors. The installation and disassembly of the reinforcing beam is simple and convenient.

[0019] In one alternative embodiment, the connector is provided with reinforcing ribs.

[0020] Beneficial effects: The reinforcing ribs are used to improve the support strength of the connectors, thereby improving the connection strength between the reinforcing beam and the top frame, making the reinforcing beam installed stably.

[0021] Secondly, this application provides a battery cabinet, including the battery frame device described in any of the above claims; each of the battery frame bodies is provided with multiple layers of battery modules to form a battery cluster.

[0022] Beneficial effects: The battery frame in the battery cabinet is equipped with reinforcing beams. When multiple battery frame bodies are lifted as a whole, the battery frame bodies are less likely to shift or misalign with each other, ensuring the accuracy of the battery cluster arrangement and assembly effect in the battery cabinet, thereby ensuring the normal use of the battery cabinet.

[0023] In one alternative embodiment, the device further includes a skid-mounted structure comprising a pair of spaced-apart bottom beams extending in a direction parallel to the first direction; the bottom of the battery frame assembly is detachably connected to the pair of bottom beams.

[0024] A beneficial effect is that a skid-mounted structure is installed at the bottom of the battery frame assembly, which facilitates the overall lifting of multiple battery frame bodies.

[0025] Thirdly, this application provides a battery energy storage system, including the aforementioned battery cabinet.

[0026] Beneficial benefits include the presence of multiple battery frame main bodies that facilitate overall lifting, as well as the ability to lift battery clusters independently and perform subsequent maintenance operations. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] Please refer to Figures 1-6 In a first aspect, embodiments of this application provide a battery frame device, including multiple battery frame bodies arranged along a first direction X; each battery frame body includes a top frame 1 and a reinforcing beam 2, wherein the reinforcing beam 2 is fixedly disposed on the top frame 1 and its axial direction is parallel to the first direction X; for any two adjacent reinforcing beams 2, one end is provided with a slot 3, the slot 3 passes through the reinforcing beam 2 along a second direction Z, and the other end is provided with a snap-fit ​​protrusion 4, the snap-fit ​​protrusion 4 being adapted to enter the slot 3 along the second direction Z and form a snap-fit ​​engagement with the slot 3.

[0044] First, it should be noted that, as Figure 1As shown, in this embodiment, the first direction X is the length direction of the battery frame device, the second direction Z is the height direction of the battery frame device, and the third direction Y is the width direction of the battery frame device. Of course, those skilled in the art can adjust the specific directions referred to by the first direction X, the second direction Z, and the third direction Y according to actual needs.

[0045] Specifically, the battery frame body serves as a frame structure, and multiple battery modules 100 are arranged inside it. The multiple battery modules 100 cooperate with the battery frame body to form a battery cluster. Multiple battery frame bodies are arranged along the first direction X, that is, multiple battery clusters are arranged along the first direction X. During the overall hoisting, the ropes are extended along the first direction X, so that the ropes are passed under the multiple battery frame bodies, so as to lift the multiple battery clusters arranged along the first direction X as a whole.

[0046] In this embodiment, refer to Figure 1 A reinforcing beam 2 is arranged on the top frame 1. At both ends of the reinforcing beam 2 along the first direction X, one end is provided with a slot 3 and the other end is provided with a snap-fit ​​protrusion 4. The slot 3 is a through hole that penetrates the upper and lower surfaces of the reinforcing beam 2. The snap-fit ​​protrusion 4 is a boss structure that matches the shape of the slot 3. The snap-fit ​​protrusion 4 can enter and exit the slot 3 through the upper and lower surfaces of the reinforcing beam 2. In two adjacent reinforcing beams 2, one reinforcing beam 2 can move vertically relative to the other reinforcing beam 2, but cannot move horizontally.

[0047] With this configuration, reinforcing beams 2 are arranged on the top frame 1 to enhance the support strength of the top frame 1. Adjacent reinforcing beams 2 are connected by slots 3 and snap-fit ​​protrusions 4 to enhance the overall lifting strength. When multiple battery frame bodies are lifted as a whole, the battery frame bodies are less likely to shift or misalign with each other, ensuring the accuracy of battery cluster arrangement and assembly effect in the battery cabinet.

[0048] With this configuration, the snap-fit ​​protrusion 4 is adapted to enter or leave the slot 3 along the second direction Z, which facilitates the separation of the main body of a single battery frame, thereby facilitating the independent lifting and subsequent maintenance of a single battery cluster.

[0049] In this embodiment, the reinforcing beam 2 is detachably connected to the top frame 1, and after hoisting, the reinforcing beam 2 is adapted to remain fixed to the top frame 1 according to the actual working conditions.

[0050] With this configuration, the reinforcing beam 2 is installed on the top frame 1. After hoisting is completed, the reinforcing beam 2 does not need to be disassembled from the top frame 1, thereby eliminating the need for disassembling the reinforcing beam 2 and making the overall hoisting operation process simpler.

[0051] In this embodiment, the hoisting process is as follows: one of the reinforcing beams 2 is fixed to the top frame 1. Then, the snap-fit ​​protrusion 4 on the other reinforcing beam 2 is aligned with the snap-fit ​​groove 3 on the already installed reinforcing beam 2, and then moved downwards along the second direction Z, so that the snap-fit ​​protrusion 4 is inserted into the snap-fit ​​groove 3. The other reinforcing beam 2 is then fixed to the top frame 1. Finally, multiple battery frame bodies are hoisted as a whole using hoisting structures such as ropes. During the overall hoisting process, the structure of the snap-fit ​​groove 3 restricts the displacement of the snap-fit ​​protrusion 4 in the horizontal plane, thereby restricting the displacement of adjacent reinforcing beams 2 in the horizontal plane, and ultimately restricting the displacement of adjacent battery frame bodies in the horizontal plane.

[0052] In this embodiment, the lifting process of a single battery cluster is as follows: a rope is installed on the battery frame body of the battery cluster to be lifted, and then the battery frame body is lifted vertically. The slots 3 and the snap-fit ​​protrusions 4 at both ends of the reinforcing beam 2 on the battery frame body are separated from the adjacent reinforcing beam 2, thereby realizing the lifting of a single battery cluster and separating the single battery cluster from the whole.

[0053] In this embodiment, the reinforcing beam 2 can be one or a combination of solid plates, hollow tubes, angle steel, channel steel, I-beams, and C-shaped steel, such as... Figure 2 As shown, the reinforcing beam 2 is made of solid plate, and its bottom surface is attached to the top surface of the top frame 1.

[0054] In one embodiment, refer to Figure 4 , Figure 5 , Figure 6 The slot 3 includes an inner cavity 301 and a slot 302. The slot 302 is connected to the inner cavity 301. The width W1 of the slot 302 is smaller than the width W2 of the inner cavity 301. The shape of the snap-fit ​​protrusion 4 is adapted to the shape of the slot 3.

[0055] Specifically, the latch 302 is closer to the adjacent reinforcing beam 2 than the inner cavity 301. When the latching protrusion 4 is located in the latching groove 3, the latch 302 restricts the movement of the latching protrusion 4 along the first direction X, that is, restricts the separation of the two adjacent battery frame bodies along the first direction X. At the same time, the cooperation between the side wall of the inner cavity 301 and the latch 302 can also restrict the movement of the latching protrusion 4 along the third direction Y.

[0056] This design restricts the horizontal displacement of the locking protrusion 4 by the slot 3, making it less likely for adjacent battery frame bodies to misalign horizontally when multiple battery frame bodies are lifted as a whole, thereby ensuring the accuracy of battery cluster arrangement and assembly effect in the battery cabinet.

[0057] Specifically, the snap-fit ​​protrusion 4 includes a first snap-fit ​​section 401 and a second snap-fit ​​section 402. The outer side wall of the first snap-fit ​​section 401 is adapted to the inner side wall of the inner cavity 301, and the outer side wall of the second snap-fit ​​section 402 is adapted to the inner side wall of the slot 302. That is, the width of the second snap-fit ​​section 402 is smaller than the width of the first snap-fit ​​section 401, so that the snap-fit ​​protrusion 4 is adapted to the slot 3.

[0058] The slot 3 has at least one inner cavity 301, and the number of inner cavities 301 is set according to actual needs. When multiple inner cavities 301 are provided, the width W1 of each inner cavity 301 is preferably increased sequentially in the direction away from the latch 302, thereby improving the fit strength between the slot 3 and the latching protrusion 4.

[0059] In one embodiment, refer to Figure 4 , Figure 5 , Figure 6 The slot 3 is one of a dovetail groove, a C-shaped groove, or a circular arc groove.

[0060] In this embodiment, the card slot 3 is configured as described above, which has a simple structure, high connection strength, and low cost of use.

[0061] Of course, in addition to the above-mentioned structure, the slot 3 can also be other structures that can restrict the movement of two adjacent reinforcing beams 2 in the horizontal direction and allow the two adjacent reinforcing beams 2 to separate in the vertical direction.

[0062] In one embodiment, refer to Figure 2 The top frame 1 includes a first beam 101, the extension direction of the first beam 101 is parallel to the first direction X, and the reinforcing beam 2 is connected to the first beam 101.

[0063] Specifically, the top frame 1 is set as a rectangular frame structure, which has two first beams 101. The two first beams 101 are arranged parallel to each other. The reinforcing beam 2 is fixed on the first beams 101. The reinforcing beam 2 can improve the support strength of the first beams 101, thereby improving the overall strength of the battery frame.

[0064] In this embodiment, the first beam 101 and the reinforcing beam 2 are set separately. The main structure of the battery frame can adopt the existing structure, and the reinforcing beam 2 is an additional structure that can be flexibly installed or removed from the first beam 101.

[0065] In one embodiment, refer to Figure 2 , Figure 3 It also includes connector 5, which is used to fix the top frame 1 and the reinforcing beam 2.

[0066] In this embodiment, the reinforcing beam 2 can be easily fixed to the top frame 1 by means of the connector 5, and the reinforcing beam 2 can be separated from the top frame 1 by disassembling the connector 5. The installation and disassembly of the reinforcing beam 2 is simple and convenient.

[0067] In one embodiment, refer to Figure 1 , Figure 2 The top frame 1 also includes a second beam 102, which is perpendicular to the first beam 101. There are two first beams 101 and two second beams 102. The two first beams 101 and the two second beams 102 cooperate to enclose and form a rectangular frame structure top frame 1. The connector 5 is fixedly connected to the first beam 101 and the reinforcing beam 2; and / or, the connector 5 is fixedly connected to the second beam 102 and the reinforcing beam 2.

[0068] Specifically, the top frame 1 is configured as a rectangular frame structure, which has two second beams 102. The two second beams 102 are arranged parallel to each other and perpendicular to the first beam 101. The two first beams 101 and the two second beams 102 are connected end to end to form the top frame 1.

[0069] In one optional embodiment, the connector 5 is configured as a plate structure, and the reinforcing beam 2 is configured as a solid plate. The plate structure is fixed to the side wall of the reinforcing beam 2 and the side wall of the first beam 101 by bolts, thereby achieving the fixation of the reinforcing beam 2 to the first beam 101 through the cooperation of the plate structure and bolts. Alternatively, the plate structure is fixed to the side wall of the reinforcing beam 2 and the second beam 102 by bolts, thereby achieving the fixation of the reinforcing beam 2 to the second beam 102 through the cooperation of the plate structure and bolts.

[0070] In another alternative implementation, refer to Figure 2 , Figure 3 The connector 5 includes a first connecting section 501 and a second connecting section 502 that are connected to each other. The first connecting section 501 and the second connecting section 502 are arranged perpendicularly, that is, the connector 5 is an L-shaped corner piece. The reinforcing beam 2 is set as a solid plate. The first connecting section 501 is fixed to the side wall of the reinforcing beam 2 by the first connecting bolt 8, and the second connecting section 502 is fixed to the second beam body 102 by the second connecting bolt 9.

[0071] Of course, in addition to the solid plate arrangement described above, the reinforcing beam 2 can also be configured as a U-shaped or C-shaped plate, with its opening facing the first beam 101 and able to cover the outside of the first beam 101. This arrangement facilitates the connection between the reinforcing beam 2 and the first beam 101.

[0072] In one embodiment, refer to Figure 2 , Figure 3 The connector 5 is provided with reinforcing ribs 6.

[0073] Specifically, when the connector 5 includes a first connecting section 501 and a second connecting section 502, at least one reinforcing rib 6 is provided between the first connecting section 501 and the second connecting section 502. The reinforcing rib 6 is used to improve the connection strength of the connector 5, making it difficult for the reinforcing beam 2 to separate from the top frame 1.

[0074] Secondly, referring to Figure 1 This application provides a battery cabinet, including any of the above-mentioned battery frame devices; each battery frame body is provided with multiple layers of battery modules 100 to form a battery cluster.

[0075] In this embodiment, the battery frame body in the battery cabinet is provided with a reinforcing beam 2. When multiple battery frame bodies are lifted as a whole, the battery frame bodies are less likely to shift or misalign with each other, ensuring the arrangement accuracy and assembly effect of the battery clusters in the battery cabinet, thereby ensuring the normal use of the battery cabinet.

[0076] In one embodiment, the device further includes a skid-mounted structure 7, which includes a pair of spaced-apart bottom beams extending in a direction parallel to a first direction X; the bottom of the battery frame assembly is detachably connected to the pair of bottom beams.

[0077] In this embodiment, a skid-mounted structure 7 is provided at the bottom of the battery frame device to facilitate the overall lifting of multiple battery frame bodies.
