Description

Technical Field

[0001] This utility model relates to the field of battery module disassembly technology, specifically to a battery module safety separation device. Background Technology

[0002] With the rapid development of energy storage devices, battery modules, as key energy storage and power supply units, are widely used in various devices that require a stable power supply. To ensure power supply reliability, battery modules are often securely installed in a connector frame using a plug-in method. However, traditional disassembly techniques have many drawbacks in scenarios that require disassembling battery modules, such as equipment maintenance and component replacement.

[0003] Currently, battery module disassembly mostly relies on manual insertion and removal, or the assistance of tools such as pry bars and wrenches. Because the connection between the battery module and the connector is tight, it is difficult to precisely control the force applied manually, and uneven force is easily caused when using tools. During disassembly, this improper method of applying force can easily lead to dents and deformation of the battery module casing, or even damage to the internal precision circuit interfaces, resulting in serious malfunctions such as short circuits.

[0004] Meanwhile, existing separation methods generally lack cushioning and shock absorption mechanisms. During the process of pushing the battery module out of the connecting frame, there are no buffer measures to mitigate the impact. This causes the battery module to shake and collide violently the moment it detaches from the connecting frame, seriously threatening the personal safety of operators and potentially triggering catastrophic accidents such as battery short circuits and fires due to the strong impact. This significantly shortens the battery module's lifespan and increases the risk of accidents.

[0005] Furthermore, existing battery module components are often single-function and dispersed, with each component operating independently, making equipment integration difficult. Moreover, this decentralized structure requires significant time and effort for maintenance and repair, further increasing the cost of industrial applications and hindering the market demand for efficient and safe maintenance. Utility Model Content

[0006] To address the problems of inaccurate force application, lack of buffering and shock absorption, and dispersed component functions in existing battery module separation methods, this utility model provides a safe battery module separation device. It aims to achieve safe, efficient, and precise separation of battery modules, reduce the risk of battery module damage, improve equipment integration, reduce maintenance costs, and meet the market demand for new energy equipment maintenance.

[0007] This utility model is achieved using the following technical solution:

[0008] A battery module safety separation device includes a mounting assembly, the mounting assembly including a mounting bracket; the mounting bracket has an embedding groove inside, the inner wall of the embedding groove is fixedly connected to a connecting bracket, and a battery module is inserted into the connecting bracket; it also includes:

[0009] Separation assembly, the separation assembly including an adjustment plate and a lower pressure plate;

[0010] The adjustment plate is disposed on the outer surface of the mounting bracket and is rotatable relative to the mounting bracket; the lower pressure plate is slidably disposed against the top of the embedding groove, and a connecting block is provided on the top of the lower pressure plate. The connecting block is fixedly disposed against one side of the adjustment plate and the adjusting plate are matched. The adjustment plate is used to adjust the lower pressure plate to move downward and push the battery module to separate from the connecting bracket.

[0011] A buffer assembly includes a top plate fixedly connected to the top of the lower pressure plate, a bottom plate fixedly connected to the bottom of the top plate via a damper, and the bottom plate fixedly connected to the top of the connecting frame, for providing a buffering effect when the lower pressure plate pushes the battery module apart.

[0012] The above technical solution offers the following advantages: This battery module safety separation device achieves efficient and safe separation through the coordinated operation of multiple components: the embedding slots and connecting frames of the mounting components provide a stable mounting foundation for the battery module; in the separation component, the adjusting disc is rotatably mounted on the outer surface of the mounting frame, and through its matching design with the connecting block, it converts the rotational motion into the linear downward pressing action of the lower pressure plate, precisely pushing the battery module to separate from the connecting frame, avoiding casing deformation and circuit damage caused by uneven manual force application; the buffer component uses a damper to connect the top plate and the bottom plate, and when the lower pressure plate pushes the battery module to separate, the damper effectively absorbs the impact force, reduces module shaking and collision, and lowers the risk of short circuit and fire. At the same time, the integrated design of the overall structure reduces space occupation, improves maintenance efficiency, and solves the technical problems of inaccurate force application, lack of buffering, and component dispersion in traditional separation methods.

[0013] As a further improvement to the above solution, the outer surface of the mounting bracket is provided with a rotating seat, the rotating seat is provided with a rotating shaft, and the adjusting disc is provided on the rotating shaft.

[0014] The above technical solution offers the following benefits: In the improved battery module safety separation device, the added rotating seat and rotating shaft structure on the outer surface of the mounting bracket provide a more stable rotational support foundation for the adjusting disc. The rotating seat, through the cooperation of the rotating shaft and the adjusting disc, significantly reduces the frictional resistance during disc rotation, making it easier and smoother for operators to rotate the disc, effectively improving operational convenience and flexibility. Simultaneously, the precise positioning of the rotating shaft ensures the adjusting disc remains stable during rotation, preventing wobbling or offset caused by installation gaps. This results in more precise meshing and transmission between the adjusting disc and the connecting block, and more stable control of the force and direction when pushing the lower pressure plate downwards. This further improves the smoothness and reliability of the battery module separation action, reduces uneven force on the battery module caused by poor disc rotation, and enhances the structural stability and service life of the entire separation device.

[0015] As a further improvement to the above solution, a handle is fixedly connected to the outer surface of the adjustment disc, and a vortex groove is formed on the inner surface of the adjustment disc, with the connecting block matching the vortex groove.

[0016] The above technical solution offers the following advantages: In the improved battery module safety separation device, the handle on the outer surface of the adjustment disc and the vortex groove design on the inner surface significantly enhance the convenience and precision of the separation operation. The handle provides a comfortable point of force application for the operator, effectively reducing the difficulty of rotating the adjustment disc and making the separation operation easier and more efficient. The precise matching of the vortex groove and the connecting block can stably and efficiently convert the rotational motion of the adjustment disc into the linear motion of the lower pressure plate. Through the special trajectory of the vortex groove, precise control of the downward pressure and speed of the lower pressure plate can be achieved, ensuring that the battery module is subjected to uniform force during the separation process and avoiding deformation of the outer shell or damage to the internal circuitry due to improper force application. At the same time, the force transmission path is optimized, greatly improving the mechanical efficiency and reliability of the separation device and further ensuring the safety and stability of the battery module separation process.

[0017] As a further improvement to the above solution, a first connecting rod is rotatably mounted on the top of the base plate, and the side of the first connecting rod away from the base plate is rotatably mounted on the bottom of the top plate.

[0018] The above technical solution offers the following advantages: In the improved battery module safety separation device, the first connecting rod added between the bottom plate and the top plate creates a stable linkage buffer structure. When the separation component pushes the battery module apart, the lower pressure plate moves the top plate downwards, and the first connecting rod rotates accordingly. During rotation, it generates a supporting force, constraining the relative movement trajectory of the top and bottom plates, preventing the top plate from tilting or swaying under force, and ensuring the smooth operation of the buffer component. Simultaneously, the rotational characteristics of the first connecting rod can disperse and transmit the impact force generated during battery module separation. Combined with the damper's buffering effect, this effectively absorbs the impact force, further reducing the impact on the battery module, minimizing the risk of damage caused by collisions, providing more reliable buffer protection for the battery module, and significantly improving the safety and stability of the entire separation device.

[0019] As a further improvement to the above solution, a movable seat is slidably installed inside the base plate, and a buffer spring is fixedly connected to the outer surface of the movable seat. The side of the buffer spring away from the movable seat is fixedly connected to the inner wall of the base plate.

[0020] The above technical solution offers the following advantages: In this improved battery module safety separation device, the sliding seat and buffer spring within the base plate form a dynamically adjustable buffer structure. When the battery module separation generates an impact force, the sliding seat slides within the base plate in the direction of the impact force, causing the buffer spring to compress and deform. The buffer spring absorbs and stores energy through elastic deformation, converting the instantaneous impact force into the elastic potential energy of the spring, effectively mitigating the direct impact of the impact force on the battery module. As the impact force weakens, the buffer spring gradually releases energy, pushing the sliding seat back to its original position, preparing for the next buffering operation. This structure, working in conjunction with the damper and the first connecting rod, forms a multi-level buffer system. This system not only more accurately adapts to impact forces of varying intensities but also effectively disperses the impact force, significantly reducing the risk of casing deformation and internal circuit damage caused by the separation impact of the battery module, further enhancing the safety and reliability of the battery module separation process.

[0021] As a further improvement to the above solution, a second connecting rod is rotatably mounted inside the movable seat. The side of the second connecting rod away from the movable seat is rotatably mounted on the bottom of the top plate, and the second connecting rod is rotatably mounted outside the first connecting rod.

[0022] The above technical solution offers the following advantages: In this improved battery module safety separation device, the linkage design of the movable seat, the second connecting rod, and the first connecting rod creates a highly efficient three-dimensional buffer mechanical structure. When the battery module separation generates an impact force, the top plate drives the second connecting rod to move. During rotation, the second connecting rod, on the one hand, drives the movable seat to slide within the base plate and compress the buffer spring through its rotational connection with the movable seat, converting the impact force into the elastic potential energy of the spring; on the other hand, the second connecting rod is sleeved outside the first connecting rod and rotates relative to it, forming a linkage mechanism similar to a parallelogram with the first connecting rod, further constraining the movement trajectory of the top plate and preventing it from tilting or deviating. The two mechanisms work together to not only disperse the impact force from multiple directions but also achieve multi-level buffering of the impact force, making the buffering effect of the buffer assembly more uniform and stable, greatly reducing the risk of damage to the battery module due to separation impact, and further improving the reliability and stability of the battery module safety separation device.

[0023] As a further improvement to the above solution, the connecting block is also provided with fixing bolts, and the connecting block and the lower pressure plate are fixedly connected by fixing bolts.

[0024] The above technical solution offers the following advantages: In the improved battery module safety separation device, the connection between the connecting block and the lower pressure plate via fixing bolts significantly enhances the structural stability and connection reliability of the separation assembly. The fixing bolts firmly secure the connecting block to the lower pressure plate. During the process where the adjusting disc drives the connecting block through the vortex groove, causing the lower pressure plate to move downwards and pushing the battery module apart, this effectively prevents the connecting block from loosening, shifting, or falling off, ensuring stable force transmission. Simultaneously, this connection method facilitates disassembly and maintenance. When it is necessary to inspect or replace the connecting block or the lower pressure plate, the operation can be quickly completed by loosening the fixing bolts. This not only ensures the stability of the separation device during operation but also improves the convenience and efficiency of equipment maintenance, reduces the risk of separation failures caused by unstable connecting components, and enhances the practicality and durability of the entire separation device.

[0038] Example 1

[0039] Please combine Figures 1 to 6 As shown, a battery module safety separation device includes a mounting assembly 1, which includes a mounting bracket 101; the mounting bracket 101 has an embedding groove 102 inside, and a connecting bracket 103 is fixedly connected to the inner wall of the embedding groove 102; a battery module 104 is inserted into the connecting bracket 103; and further includes:

[0040] Separation component 2, which includes an adjustment plate 201 and a lower pressure plate 202;

[0041] An adjustment plate 201 is disposed on the outer surface of the mounting bracket 101 and is rotatable relative to the mounting bracket 101; a lower pressure plate 202 is slidably disposed against the top of the embedded groove 102, and a connecting block 203 is provided on the top of the lower pressure plate 202. The connecting block 203 is fixedly disposed against one side of the adjustment plate 201 and is matched with the adjustment plate 201. The adjustment plate 201 is used to adjust the lower pressure plate 202 to move downward and push the battery module 104 to separate from the connecting bracket 103.

[0042] The buffer assembly 3 includes a top plate 301 fixedly connected to the bottom of the lower pressure plate 202. The bottom of the top plate 301 is fixedly connected to a bottom plate 303 via a damper 302. The bottom plate 303 is fixedly connected to the top of the connecting frame 103 and is used to provide a buffering effect when the lower pressure plate 202 pushes the battery module 104 to separate.

[0043] This battery module safety separation device achieves safe and efficient separation of the battery module 104 through the coordinated operation of the mounting component 1, the separation component 2, and the buffer component 3. In the mounting component 1, the embedding groove 102 of the mounting bracket 101 and the connecting bracket 103 provide a stable mounting space for the battery module 104. In the separation component 2, the adjusting plate 201 is rotatably set on the outer surface of the mounting bracket 101. Through the matching design with the connecting block 203, the rotational motion is precisely converted into the linear pressing action of the lower pressure plate 202, effectively avoiding problems such as deformation of the battery module 104 shell and damage to the circuit interface caused by uneven force during manual disassembly. The buffer component 3 uses a damper 302 to connect the top plate 301 and the bottom plate 303. At the moment when the lower pressure plate 202 pushes the battery module 104 to separate, the damper 302 absorbs the impact force in time, significantly reducing the shaking and collision of the battery module 104 when it detaches from the connecting bracket 103, greatly reducing safety hazards such as short circuits and fires, and improving the safety of operators. The device has a compact overall structure and a high degree of integration, which effectively overcomes the shortcomings of traditional separation methods that are single-function and scattered, greatly reduces equipment maintenance costs, and significantly improves the reliability and stability of battery module 104 separation.

[0044] In this embodiment, the outer surface of the mounting bracket 101 is provided with a rotating seat 105, the rotating seat 105 is provided with a rotating shaft 106, and the adjusting disk 201 is provided on the rotating shaft 106;

[0045] By adding a rotating seat 105 and a rotating shaft 106 to the outer surface of the mounting bracket 101, a stable and flexible rotating foundation is constructed for the adjustment plate 201. The rotating shaft 106 is precisely installed on the rotating seat 105, which effectively reduces friction and shaking during the rotation of the adjusting disk 201, ensuring its smooth and stable rotation. When the operator drives the lower pressure plate 202 to move down by rotating the adjusting disk 201, the cooperation between the rotating shaft 106 and the rotating seat 105 ensures that the adjusting disk 201 transmits the rotational force to the connecting block 203 more efficiently and stably, avoiding transmission deviation caused by unstable installation of the adjusting disk 201. This ensures that the lower pressure plate 202 smoothly pushes the battery module 104 to separate from the connecting frame 103, improving the reliability and accuracy of the entire separation process and reducing the risk of battery module 104 separation failure caused by unreasonable installation structure of the adjusting disk 201. It should be further noted that the rotating seat 105 and rotating shaft 106 added to the outer surface of the mounting frame 101, and the fact that the adjusting disk 201 can rotate on the rotating shaft 106, are existing conventional technologies and will not be described in detail.

[0046] In this embodiment, a handle 204 is fixedly connected to the outer surface of the adjustment disk 201, and a vortex groove 205 is opened on the inner surface of the adjustment disk 201. The connecting block 203 is matched with the vortex groove 205.

[0047] By designing a handle 204 on the outer surface of the adjustment disc 201 and a vortex groove 205 on its inner surface, the separation process is significantly optimized in terms of both ease of operation and transmission precision. The handle 204 provides the operator with a comfortable and easy-to-apply force point, greatly reducing the difficulty of rotating the adjustment disc 201 and making the separation operation easier, more efficient, and more convenient. The precise matching between the vortex groove 205 and the connecting block 203 can stably and accurately convert the rotational motion of the adjustment disc 201 into the linear motion of the lower pressure plate 202. Through the special trajectory design of the vortex groove 205, precise control of the downward pressure and speed of the lower pressure plate 202 can be achieved, ensuring that the battery module 104 is subjected to uniform and stable force during the separation process. This effectively avoids problems such as shell deformation and internal circuit damage caused by improper force application, greatly improving the mechanical efficiency and reliability of the separation device, and further ensuring the safety and stability of the battery module 104 separation process.

[0048] In this embodiment, a first connecting rod 304 is rotatably mounted on the top of the base plate 303, and the side of the first connecting rod 304 away from the base plate 303 is rotatably mounted on the bottom of the top plate 301.

[0049] Specifically, a movable seat 305 is slidably installed inside the base plate 303, and a buffer spring 306 is fixedly connected to the outer surface of the movable seat 305. The side of the buffer spring 306 away from the movable seat 305 is fixedly connected to the inner wall of the base plate 303.

[0050] A second connecting rod 307 is rotatably mounted inside the movable base 305. The side of the second connecting rod 307 away from the movable base 305 is rotatably mounted on the bottom of the top plate 301. The second connecting rod 307 is rotatably mounted on the outside of the first connecting rod 304.

[0051] A multi-level three-dimensional buffer system is constructed through the coordinated action of the base plate 303, the first connecting rod 304, the movable seat 305, the buffer spring 306, and the second connecting rod 307. The first connecting rod 304 connects the base plate 303 and the top plate 301, and constrains the movement trajectory of the top plate 301 by rotation, ensuring buffer stability. The movable seat 305 and the buffer spring 306 form an elastic buffer unit. When the battery module 104 separates and generates an impact force, the movable seat 305 slides within the base plate 303 to compress the buffer spring 306, converting the impact force into elastic potential energy for absorption. The second connecting rod 307 forms a linkage structure with the first connecting rod 304, which on the one hand assists in constraining the movement of the top plate 301, and on the other hand, cooperates with the sliding of the movable seat 305 to further disperse the impact force. This system absorbs and disperses the impact force from multiple angles and dimensions. Compared with a single buffer structure, it can more effectively deal with complex impact conditions, significantly reduce the risk of shell deformation and internal circuit damage caused by impact during the separation of the battery module 104, and greatly improve the reliability and protection performance of the battery module safety separation device.

[0052] In this embodiment, the connecting block 203 is also provided with a fixing bolt 206, and the connecting block 203 and the lower pressure plate 202 are fixedly connected by the fixing bolt 206;

[0053] By fixing the connecting block 203 and the lower pressure plate 202 with fixing bolts 206, this design effectively strengthens the structural strength and connection reliability of the separation assembly 2. During the process where the adjusting disc 201 drives the connecting block 203 to move the lower pressure plate 202 downwards, pushing the battery module 104 to separate, the fixing bolts 206 firmly lock the connecting block 203 and the lower pressure plate 202, preventing loosening, displacement, or detachment due to force, ensuring stable force transmission during separation, and guaranteeing the accuracy and stability of the separation action. Simultaneously, this connection method has good disassembly capability. When it is necessary to inspect, replace, or adjust the connecting block 203 and the lower pressure plate 202, operators can quickly complete the operation by tightening the fixing bolts 206, significantly improving the convenience and efficiency of equipment maintenance, reducing the risk of separation failure due to unstable connections, and further enhancing the practicality and durability of the entire separation device.

[0054] Working principle of this utility model:

[0055] First, the battery module 104 is securely inserted into the connecting bracket 103 of the mounting assembly 1. The embedding groove 102 of the mounting bracket 101 provides a stable base environment for the entire separation process. When it is necessary to separate the battery module 104, the operator holds the handle 204 on the outer surface of the adjustment disc 201 and rotates the adjustment disc 201. The adjustment disc 201 is mounted on the rotation shaft 106 of the rotating seat 105 on the outer surface of the mounting bracket 101 and can rotate flexibly. Its internal vortex groove 205 matches the connecting block 203. As the adjustment disc 201 rotates, the vortex groove 205 drives the connecting block 203, causing the lower pressure plate 202 to slide downward at the top of the embedding groove 102.

[0056] As the lower pressure plate 202 pushes the battery module 104 downward to separate from the connecting frame 103, the buffer assembly 3 simultaneously functions. The lower pressure plate 202 causes the top plate 301 to move downward. At this time, the damper 302 at the bottom of the top plate 301 first acts as a buffer, slowing down the descent speed of the top plate 301. Simultaneously, the first connecting rod 304 at the top of the bottom plate 303 is rotatably connected to the top plate 301, rotating as the top plate 301 moves downward, constraining the movement trajectory of the top plate 301 and preventing it from tilting. The movable seat 305 inside the bottom plate 303 slides under the impact force, compressing the buffer spring 306 on the outer surface, converting the impact force into elastic potential energy, further absorbing energy. The second connecting rod 307 inside the movable seat 305 forms a linkage structure with the first connecting rod 304, assisting in constraining the movement of the top plate 301 and dispersing the impact force from multiple directions.

[0057] Furthermore, the connecting block 203 is securely connected to the lower pressure plate 202 via fixing bolts 206, ensuring stable force transmission during separation and preventing loose connections from affecting the separation effect. Ultimately, with the coordinated cooperation of all components, the battery module 104 separates smoothly and safely from the connecting frame 103, avoiding battery module damage and safety hazards caused by uneven force application and lack of buffering in traditional separation methods.
