Description

Technical Field

[0001] This utility model relates to the field of energy storage battery technology, and in particular to a fixing structure for insert boxes and battery cluster racks, and an energy storage container. Background Technology

[0002] In the field of energy storage containers, battery clusters, as the core energy storage unit, are crucial for structural stability and safety. Typically, multiple battery packs are integrated into a battery cluster frame via inserts, forming a complete battery cluster. Therefore, the reliability of the fixation between the inserts and the cluster frame directly determines the entire energy storage system's ability to withstand external forces such as vibration and impact during transportation and operation, making it a key element in ensuring system safety.

[0003] Currently, there are two main types of common box-mounting methods in the industry, but both have inherent drawbacks. The first method involves only securing the front end of the box with bolts, while leaving the rear end free. This method is simple in structure, but in practical applications, especially during long-distance transportation, the lack of effective restraint at the rear end of the box can cause significant swaying, posing a risk of insufficient installation reliability.

[0004] To improve the end-fixation problem, a second improved solution, as disclosed in Chinese Patent CN117059991A, has emerged. This solution, while retaining the front-end bolt fixing, adds a U-shaped bracket to the end of the insertion box, intending to limit its movement by pressing down on the box. However, this design still fails to completely solve the problem in practice. To ensure the insertion box can be smoothly pushed into the cluster frame, a certain assembly gap must be reserved between the U-shaped bracket and the mating surface of the insertion box. It is this unavoidable gap that allows the end of the insertion box to still have room to "jump" when subjected to continuous vibration, preventing true rigid fixation and failing to fundamentally improve the fixing effect. Utility Model Content

[0005] In view of this, the present invention proposes a fixing structure for the insertion box and the battery cluster frame and an energy storage container to solve the problem that the rigid constraint between the insertion box end and the battery cluster is insufficient in the prior art, which leads to easy displacement and jumping when encountering continuous vibration.

[0006] The technical solution of this utility model is implemented as follows: This utility model provides a fixing structure for a battery pack and a battery cluster rack. The battery cluster rack includes a support plate with a horizontal plate and side plates. The battery pack includes a side beam supported by the horizontal plate. The fixing structure includes: Multiple positioning components are rotatably disposed on the side plate at intervals along the pushing direction of the insertion box, and the height of their pressing ends from the horizontal plate decreases step by step along the pushing direction. An elastic element is disposed between the side plate and each of the positioning members, for providing an elastic force to the positioning members to give them a tendency to rotate in the pressing direction; Multiple mating parts are spaced apart on the side beam along the pushing direction, and their heights decrease progressively along the pushing direction. The height arrangement of the mating parts matches the height arrangement of the positioning parts. When the insert box is pushed into the assembly position, the pressing end of each positioning part presses against the corresponding mating part under the action of the elastic force to lock the insert box.

[0007] Based on the above technical solution, preferably, a rotating shaft is fixedly provided on the side plate, the positioning member is rotatably disposed on the rotating shaft, and the elastic element is a torsion spring, which is sleeved on the rotating shaft, one end of which is fixedly connected to the side plate, and the other end is connected to the positioning member and applies force to it.

[0008] Based on the above technical solution, preferably, the positioning component includes a first baffle and a second baffle that are perpendicularly connected to each other. One end of the torsion spring acts on the first baffle to provide rotational force for the positioning component. A limiting part is fixedly provided on the side plate to limit the rotation angle of the positioning component and keep it in a predetermined initial position.

[0009] Based on the above technical solution, preferably, the first baffle is configured such that, when the positioning member is in the initial position, the vertical distance between the lowest point of the first baffle and the top surface of the side beam is less than the height of the non-pressurized mating member.

[0010] Based on the above technical solution, preferably, the second baffle is configured such that, when the positioning member is in the initial position, the vertical distance between the bottom end of the second baffle and the side beam is greater than the height of the mating member that is pressed and engaged by the positioning member.

[0011] Based on the above technical solution, preferably, the length of the first baffle is greater than or equal to the length of the second baffle.

[0012] Based on the above technical solution, preferably, the horizontal plate insertion end is provided with a connecting hole for fixing the front end of the insertion box with bolts.

[0013] Based on the above technical solution, preferably, the number of the positioning component and the mating component are both two, respectively located near the middle and end of the insertion box.

[0014] Secondly, this utility model discloses an energy storage container, including a battery cluster frame and a plug box, and also includes the plug box and battery cluster frame fixing structure described in the first aspect, wherein the plug box is fixedly connected to the battery cluster frame through the fixing structure.

[0015] The present invention has the following advantages over the prior art: (1) By combining the decreasing and matching arrangement of positioning and mating parts with an adaptive clamping mechanism driven by elastic elements, a fixed structure is constructed that allows for interference-free sliding during the insertion of the battery pack and automatic multi-point locking after assembly. This structure fundamentally eliminates the space for movement caused by assembly gaps, achieves rigid constraint at the end of the battery pack, and significantly improves the battery pack's ability to resist vibration and impact during operation.

[0016] (2) By setting the positioning component as an L-shaped lever consisting of a first baffle and a second baffle, and optimizing the application point of the torsion spring and adding a limiting part, an efficient, reliable and precise automatic locking mechanism is realized. The L-shaped lever structure gives it the advantages of saving effort and amplifying the clamping force; the design of the torsion spring acting on the first baffle optimizes the torque transmission efficiency; and the limiting part ensures the accuracy of the starting point of the mechanism's action and the safety of the process. These three work together to ensure that the box fixing process is smooth and error-free, the locking effect is solid and reliable, and greatly enhances the stability of the fixing structure when facing vibration and impact.

[0017] (3) By limiting the height relationship between the second baffle and the mating parts, it is ensured that the mating parts can pass smoothly under the second baffle in the initial stage of the insertion box, avoiding motion interference; when the insertion box reaches the predetermined position, the second baffle can be effectively pressed down under the lever principle to form reliable vertical and horizontal constraints, thereby significantly improving the stability and vibration resistance of the fixed structure.

[0027] like Figure 1 As shown, combined with Figure 2-7 This utility model embodiment discloses a fixing structure 3 for the insertion box 2 and the battery cluster frame 1. The mounting base of the fixing structure 3 includes the support plate 11 of the battery cluster frame 1 and the side beam 21 of the insertion box 2.

[0028] The support plate 11 consists of a horizontal plate 111 and a side plate 112. The horizontal plate 111 bears the main weight support function of the insertion box 2, while the side plate 112 serves as the mounting carrier for the movable positioning components. The side beam 21 of the insertion box 2 serves as the connection interface and rests on the horizontal plate 111 during assembly. This basic structure provides a stable mounting platform and a clear spatial relationship for the subsequent clamping mechanism, ensuring that the entire fixing system can work reliably within a defined three-dimensional space.

[0029] The fixing structure 3 includes multiple positioning elements 31, multiple mating elements 33, and elastic elements 32.

[0030] Multiple positioning elements 31 are rotatably mounted on the side plate 112 at intervals along the pushing direction of the insertion box 2, with the height of their pressing ends from the horizontal plate 111 decreasing progressively along the pushing direction. This spatial arrangement forms a stepped structural array, with each positioning element 31 assigned a specific height coordinate. The "rotatable" characteristic of the positioning elements 31 gives them dynamic response capabilities, allowing them to rotate and displace when the insertion box 2 is pushed in, thus making way for the insertion box 2's movement. The decreasing height arrangement strategy ensures that during the insertion of the insertion box 2, mating parts 33 of different heights can interact with their corresponding positioning elements 31 in a predetermined order, avoiding movement interference.

[0031] An elastic element 32 is disposed between the side plate 112 and each of the positioning members 31, for providing the positioning members 31 with an elastic force that causes them to rotate in the pressing direction.

[0032] The elastic element 32 serves as the power source for the fixed structure 3, providing a continuous elastic force to each positioning element 31, thus enabling the positioning element 31 to automatically reset. When the insert box 2 is pushed in, forcing the positioning element 31 to rotate, the elastic element 32 stores potential energy; when the insert box 2 reaches the assembly position, the elastic element 32 releases the energy, driving the positioning element 31 to quickly return to the clamping state. This design gives the fixed structure 3 self-adaptive capabilities, automatically compensating for manufacturing tolerances of parts and wear caused by long-term use, ensuring a stable clamping effect under different working conditions.

[0033] Multiple mating parts 33 are spaced apart on the side beam 21 along the pushing direction, and their heights decrease gradually along the pushing direction. The height arrangement of the mating parts 33 matches the height arrangement of the positioning parts 31.

[0034] The mating parts 33 adopt a "gradually decreasing height" layout corresponding to the positioning parts 31, and their heights are matched. This structural arrangement ensures that each positioning part 31 has a unique corresponding mating part 33 as a clamping target. When the insert box 2 begins to be pushed in, the shortest mating part 33 on the side beam 21 (located at the front) enters the cluster first. Due to its lowest height, it can pass smoothly under the clamping end of the tallest positioning part 31 (located at the rear), maintaining a safe gap between them without any contact or mechanical interference.

[0035] As the insert box 2 is continuously pushed in, the slightly taller mating parts 33 pass under the slightly shorter positioning parts 31 in sequence. Since the height of the mating parts 33 is always less than or equal to the clearance height under the positioning parts 31 they are currently passing, all mating parts 33 and all positioning parts 31 are in a "non-contact" state throughout the entire pushing process. Only when the insert box 2 reaches the final assembly position do the two form a precise mating relationship. This space-time separation design ensures both the smoothness of the insert box 2 pushing process and the reliability of the final locking state.

[0036] When the insert box 2 is pushed into the assembly position, each of the positioning members 31 presses its pressing end against the corresponding mating member 33 under the action of the elastic force, so as to lock the insert box 2.

[0037] When the insert box 2 is pushed into the assembly position, the system enters the locking stage. Driven by elastic force, each positioning component 31 moves synchronously, its pressing end precisely pressing against the corresponding mating component 33 from different height positions. This process achieves multi-point constraint on the insert box 2, preventing further movement in the horizontal direction through friction locking and mechanical limiting, and eliminating runout gaps in the vertical direction through continuous downward pressure. The synergistic effect of multiple locking points forms a three-dimensional constraint network, making the insert box 2 and the cluster frame a rigid whole, significantly improving vibration and impact resistance.

[0038] By combining the decreasing and matching arrangement of positioning components 31 and mating components 33 with an adaptive clamping mechanism driven by elastic element 32, an intelligent fixing structure 3 is constructed that allows for interference-free sliding during the insertion of the insert box 2 and automatic multi-point locking after assembly. This structure fundamentally eliminates the space for movement caused by assembly gaps, achieves rigid constraint at the end of the insert box 2, and significantly improves the insert box's ability to resist vibration and impact during operation.

[0039] In some implementations, a rotating shaft 1121 is fixedly mounted on the side plate 112, providing a stable center of rotation for the entire positioning component 31. The positioning component 31 is rotatably mounted on the rotating shaft 1121, forming a rotating pair with the rotating shaft 1121. This installation method ensures that the rotational movement of the positioning component 31 is constrained to a single axis, and the movement trajectory is precisely controllable, avoiding jamming or wobble that may occur under multiple degrees of freedom, thus laying a mechanical foundation for subsequent precise clamping actions.

[0040] The elastic element 32 is a torsion spring, a standard elastic element 32 that stores and releases energy through torsional deformation, and its characteristics are very suitable for providing rotational torque. The elastic element 32 is sleeved on the rotating shaft 1121, meaning that the torsion spring and the positioning element 31 share the same rotating shaft 1121 as the mounting mandrel. This coaxial design greatly optimizes the spatial layout, making the structure very compact.

[0041] One end of the elastic element 32 is fixedly connected to the side plate 112, and the other end is connected to the positioning member 31, applying force to it. This defines a clear and efficient force transmission path: fixed side plate 112 → one end of the torsion spring (fixed point) → torsion spring body (torsional deformation) → the other end of the torsion spring (free end) → positioning member 31. The fixed point on the side plate 112 provides reaction force support. When the positioning member 31 rotates due to the insertion of the insert box 2, it forces the torsion spring to torsion and store energy; when the external force disappears, the torsion spring releases its elastic potential energy, driving the positioning member 31 to rotate in the opposite direction and reset. This connection method is direct and reliable, ensuring that the force is accurately applied to the positioning member 31, giving it a continuous rotational tendency (i.e., torque) in the pressing direction, thereby achieving automatic pressing of the mating part 33 on the side beam 21.

[0042] This embodiment illustrates one structural form of the positioning component 31. Specifically, the positioning component 31 includes a first baffle 311 and a second baffle 312 that are perpendicularly connected to each other, thereby forming an L-shaped lever. The first baffle 311 and the second baffle 312 are perpendicularly connected, creating two clearly defined arms in space. This L-shaped structure is a classic lever form in mechanical design, and its core advantage lies in its ability to amplify force and change direction. In this scheme, the first baffle 311 serves as the power arm that receives the driving force, while the second baffle 312 serves as the clamping end that performs the clamping action. When force is applied to the first baffle 311, a larger force or more precise displacement can be generated at the end of the second baffle 312 through the lever effect, which is crucial for achieving a strong locking force.

[0043] One end of the torsion spring acts on the first baffle 311 to provide rotational force to the positioning member 31.

[0044] In some implementations, the length of the first baffle 311 is greater than or equal to the length of the second baffle 312. Preferably, the length of the first baffle 311 is greater than the length of the second baffle 312. By applying the force of the torsion spring to the longer first baffle 311, rather than directly to the shorter second baffle 312, the system makes full use of the lever principle. Specifically, a smaller torsion spring force applied to the end of the first baffle 311 can generate an amplified clamping force at the clamping end of the second baffle 312. This design not only makes the mechanism more labor-saving and allows the use of smaller torsion springs, thereby reducing costs and extending service life, but also ensures that the positioning member 31 can be easily pushed open during the insertion of the insert 2, while providing sufficient holding force when locking is required.

[0045] A limiting part 1122 is fixedly provided on the side plate 112 to limit the rotation angle of the positioning member 31, keeping it in a predetermined initial position. The limiting part 1122 provides a rigid physical stop for the positioning member 31 when the insert box 2 is not inserted. By abutting against a part of the positioning member 31, preferably a second baffle 312, the limiting part 1122 precisely limits the maximum rotation angle of the positioning member 31 under the preload of the torsion spring, thereby stably keeping it in a "predetermined initial position". This initial position ensures that when the insert box 2 is initially pushed in, the mating part 33 on its side beam 21 has an unobstructed path to pass under the positioning member 31, avoiding initial interference. At the same time, it also prevents the positioning member 31 from excessively rotating under the action of the torsion spring, thereby protecting the torsion spring from excessive deformation and ensuring that the starting point of each action is consistent, improving the repeatability and reliability of the entire mechanism.

[0046] By specifying the positioning element 31 as an L-shaped lever composed of a first baffle 311 and a second baffle 312, and optimizing the application point of the torsion spring and adding a limiting part 1122, a highly efficient, reliable, and precise automatic locking mechanism is achieved. The L-shaped lever structure gives it the advantages of saving effort and amplifying the clamping force; the design of the torsion spring acting on the first baffle 311 optimizes the torque transmission efficiency; and the limiting part 1122 ensures the accuracy of the starting point of the mechanism's action and the safety of the process. These three work together to ensure that the fixing process of the insertion box 2 is smooth and error-free, the locking effect is solid and reliable, and greatly enhances the stability of the fixing structure 3 when facing vibration and impact.

[0047] As one implementation, the first baffle 311 is configured such that, when the positioning member 31 is in the initial position, the vertical distance between the lowest point of the first baffle 311 and the top surface of the side beam 21 is less than the height of the non-pressurized mating member 33.

[0048] By adopting the above technical solution, it can be ensured that during the insertion of the insert box 2, the mating parts 33 that do not participate in the final clamping (i.e., non-clamping mating parts 33) can pass smoothly through the space area below the first baffle 311. Since the vertical distance between the lowest point of the first baffle 311 and the top surface of the side beam 21 is less than the height of the non-clamping mating parts 33, these higher mating parts 33 will not come into contact or collide with the first baffle 311 during the movement, thus achieving truly interference-free movement.

[0049] As one implementation, the second baffle 312 is configured such that, when the positioning member 31 is in the initial position, the vertical distance between the bottom end of the second baffle 312 and the side beam 21 is greater than the height of the mating member 33 that is pressed and engaged by the positioning member 31.

[0050] When the insert box 2 is pushed in, the mating part 33 first enters the space below the second baffle 312. Since the vertical distance between the bottom end of the second baffle 312 and the side beam 21 is greater than the height of the mating part 33, a safety gap is formed between them. During the pushing process, the mating part 33 remains in non-contact with the positioning part 31 and slides smoothly along the preset path.

[0051] As the mating part 33 continues to advance to the predetermined position, it begins to contact the first baffle 311. The thrust causes the positioning part 31 to rotate around the rotation axis 1121, at which point the L-shaped lever principle comes into play. The first baffle 311 acts as the power arm, receiving the thrust and transmitting the motion to the second baffle 312 through the lever effect. As the positioning part 31 rotates, the second baffle 312 gradually presses down. When the insert box 2 is fully in the assembly position, the second baffle 312 presses tightly against the top surface of the mating part 33 under the action of the torsion spring. At this time, the mating part 33 is subjected to a vertical clamping force from the second baffle 312, and at the same time, due to the self-locking effect of the L-shaped lever, horizontal movement is also completely constrained.

[0052] By limiting the height relationship between the second baffle 312 and the mating part 33, it is ensured that the mating part 33 can pass smoothly under the second baffle 312 in the initial stage of the insertion box 2, avoiding motion interference; when the insertion box 2 reaches the predetermined position, the second baffle 312 can be effectively pressed down under the action of the lever principle, forming reliable vertical and horizontal constraints, thereby significantly improving the stability and vibration resistance of the fixed structure 3.

[0053] When the insertion box 2 reaches the predetermined position in the battery cluster 1, under the action of the positioning member 31 and the mating member 33, the insertion box 2 will be unable to move forward. At this time, in order to prevent the insertion box 2 from coming out horizontally, this embodiment also provides a connecting hole 1110 at the insertion end of the horizontal plate 111 for fixing the front end of the insertion box 2 with bolts.

[0054] Specifically, after the insertion box 2 is inserted into the battery cluster rack 1, the front end of the insertion box 2 and the connecting hole 1110 are locked with bolts, thereby achieving reliable positional constraint of the insertion box 2 in the horizontal and vertical directions in the battery cluster rack 1, avoiding movement of the insertion box 2 caused by vibration and impact, and completely solving the problem of the end of the insertion box 2 jumping.

[0055] It should be noted that when the plug box 2 needs to be removed from the battery rack 1, the bolts at the front end of the plug box 2 should be removed first, and then the plug box 2 should be dragged and moved along the opening end of the battery rack 1. At this time, the mating part 33 will disengage from the positioning part 31, so that the plug box 2 can be smoothly removed from the battery rack 1 for easy replacement or maintenance.

[0056] In some implementations, both the positioning element 31 and the mating element 33 are in pairs, respectively positioned near the middle and end of the insertion box 2. This dual-point arrangement at the middle and end makes the constraint force distribution more reasonable. When the insertion box 2 is subjected to vibration and impact, the two locking points can share the load, avoiding stress concentration. Compared to three-point or multi-point fixing, this significantly simplifies the structural complexity and reduces manufacturing costs.

[0057] This utility model also discloses an energy storage container, as shown in the attached drawing. Figure 8 As shown, it includes a battery cluster frame 1 and a plug box 2, and also includes the plug box 2 and the battery cluster frame 1 fixing structure 3 mentioned in the first aspect. The plug box 2 is fixedly connected to the battery cluster frame 1 through the fixing structure 3.

[0058] In this embodiment, the battery cluster frame 1 consists of two rows of vertically arranged uprights 12. Each row of uprights 12 has multiple support plates 11 spaced apart along the vertical direction. The battery cluster frame 1 is fixedly installed inside the container body by the uprights 12. The space between the two rows of uprights 12 forms the installation space for the insert box 2, and the insert box 2 is supported by the two support plates 11.

[0059] This energy storage container integrates the fixed structure 3 disclosed in the above embodiments, realizing an intelligent rigid connection between the insert box 2 and the battery cluster frame 1. Its technical effects are significant in that: the use of a highly matched positioning component 31 and mating component 33 system allows the insert box 2 to undergo interference-free smooth guidance during the pushing process, and the positioning component 31 drives the rotation to achieve multi-point synchronous locking, completely eliminating the displacement and jumping space at the end of the insert box 2; the adaptive clamping characteristics of the elastic element 32 ensure that the vertical clamping force and horizontal displacement constraint are maintained continuously under vibration and impact environment, greatly improving the overall stability and safety of the energy storage container during transportation and operation.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
