Description

Technical Field

[0001] This application relates to the technical field of capacitors, and in particular to a vibration-resistant supercapacitor energy storage module. Background Technology

[0002] Supercapacitors, as a novel energy storage device, have been widely used in the field of energy storage in recent years. With the rapid development of industries such as electronic equipment, electric vehicles, and smart grids, the performance requirements for energy storage devices are becoming increasingly stringent. Due to their advantages such as high power density, long cycle life, and rapid charge / discharge, supercapacitors have become one of the ideal alternatives to traditional batteries, playing a vital role in numerous fields and driving technological progress and development in related industries.

[0003] In existing related technologies, simple partitions or fillers are used for fixation, resulting in poor overall structural integrity. Under complex vibrations, relative displacement easily occurs between components, leading to stress concentration on individual capacitor cells. Other solutions use elastic elements for buffering, which can absorb some vibrations, but cannot provide sufficient rigid support under high-intensity impacts. Therefore, there is an urgent need in the field for a structure that can provide high rigidity support and is easy to install and disassemble. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a vibration-resistant supercapacitor energy storage module.

[0005] The vibration-resistant supercapacitor energy storage module provided in this application adopts the following technical solution: A vibration-resistant supercapacitor energy storage module, comprising:

[0006] A box body, the box body including a receiving cavity;

[0007] The fixing assembly includes two single-sided clamps and at least one double-sided clamp, with the at least one double-sided clamp located between the two single-sided clamps, and the single-sided clamps and the double-sided clamps being arranged parallel to each other at intervals within the receiving cavity;

[0008] At least one supercapacitor cell, the supercapacitor cell being fixed between each of the single-sided clamps and the double-sided clamps in an axially extending direction; and

[0009] Multiple support columns are provided, which pass through the double-sided clamping plate and abut against the single-sided clamping plate at both ends, and are then fixed to the side wall of the box body.

[0010] By adopting the above technical solution, the housing cavity provides installation space for each component. The parallel arrangement of the single-sided and double-sided clamps of the fixing assembly stably places the supercapacitor cells. Fixing the supercapacitor cells between the single-sided and double-sided clamps effectively secures them and isolates them from contact with the metal shell. The support columns are fixed at both ends to the housing, pass through the double-sided clamps, and abut against the single-sided clamps, enhancing structural stability, improving the vibration resistance of the entire energy storage module, and facilitating installation and disassembly. The combination of the support columns, single-sided clamps, and double-sided clamps forms an independent, highly rigid spatial frame structure inside the module, facilitating disassembly and installation. This frame structure effectively disperses external vibration stress, preventing stress concentration on individual capacitors or their electrical connection points.

[0011] Preferably, the box body includes a frame, a bottom plate, and a cover plate. The frame is fixedly connected to the bottom plate to define the receiving cavity, and the surface of the support column opposite to the bottom plate is also fixed to the cover plate.

[0012] By adopting the above technical solution, a box is formed by a frame, a base plate, and a cover plate. The frame is fixed to the base plate, and the cover plate is fixed to the support column, so that the supercapacitor cell is placed in a stable and closed environment, which enhances the structural stability of the entire energy storage module and further improves its vibration resistance.

[0013] Preferably, the single-sided clamp and the double-sided clamp each have multiple limiting slots on their opposing surfaces that cooperate with the supercapacitor cell, and the supercapacitor cell is engaged in the limiting slots.

[0014] By adopting the above technical solution, the single-sided clamping plate and the double-sided clamping plate are opened with limiting slots and the supercapacitor cells are clamped in them, which can effectively limit the supercapacitor cells and improve the vibration resistance and stability of the supercapacitor energy storage module.

[0015] Preferably, each pair of supercapacitor cells located in the middle of the double-sided clamping plate and the single-sided clamping plate are electrically connected by a first connecting piece, and the supercapacitor cells located at both ends of the double-sided clamping plate are electrically connected by a second connecting piece. Both the first connecting piece and the second connecting piece are fixedly connected in the limiting slot.

[0016] By adopting the above technical solution, the first connecting piece and the second connecting piece are used to realize the electrical connection at different positions of the supercapacitor cells and fix them in the limiting slot, so as to ensure that the connection between the supercapacitor cells is stable and reliable, and the supercapacitor energy storage module has good electrical performance and stability.

[0017] Preferably, the limiting slot includes a positive electrode slot and a negative electrode slot. The positive electrode slot and the negative electrode slot located in the middle of the double-sided clamp and the single-sided clamp are arranged in pairs and connected together. A positive electrode slot and a negative electrode slot are provided at both ends of the double-sided clamp and on the same plane and opposite sides.

[0018] By adopting the above technical solution, the supercapacitor cells are stably fixed by combining the receiving cavity, the parallel single-sided clamping plate and double-sided clamping plate, the support column passing through the double-sided clamping plate and abutting the single-sided clamping plate, the supercapacitor cells snapped into the limiting slots, and the positive and negative electrode slots connected in pairs in the middle and at the single-sided clamping plate, as well as the positive and negative electrode slots with specific layouts at both ends. This facilitates the electrical series connection layout of the supercapacitor cells, optimizes the internal structure and electrical connection method of the supercapacitor energy storage module, and improves the reliability and stability of the module.

[0019] Preferably, the support column is provided with an installation part and a snap-fit ​​part, and both the single-sided clamp and the double-sided clamp are provided with fixing holes. The support column passes through the installation part into the fixing holes and is fixed by the snap-fit ​​part.

[0020] By adopting the above technical solution, the mounting part of the support column passes through the fixing holes of the single-sided and double-sided clamping plates, and then the clamping part is used for limiting and fixing. This allows the support column to effectively connect the single-sided and double-sided clamping plates, improving the structural stability of the entire vibration-resistant supercapacitor energy storage module and enhancing the module's vibration resistance.

[0021] Preferably, each pair of adjacent supercapacitor cells is defined as an energy storage group, and each energy storage group is provided with a corresponding support column. Each support column is located between the two rows of supercapacitor cells in an energy storage group, and the cross-section of the support column (4) includes a square portion and a circular portion. The fixing hole is a non-circular hole adapted to the square portion, so that when the support column passes through the fixing hole, the rotation of the support column is restricted by the cooperation between the square portion and the non-circular hole. Furthermore, the circular portion abuts against the surface of the two adjacent rows of supercapacitor cells to support the supercapacitor cells.

[0022] By adopting the above technical solution, a vibration-resistant supercapacitor energy storage module is formed by a receiving cavity, a single-sided clamping plate, a double-sided clamping plate, a supercapacitor unit, and a support column, which can enhance the overall structural stability and vibration resistance of the module. The support column passes through the mounting holes of the single-sided and double-sided clamping plates through the mounting part and is fixed by the snap-fit ​​part to ensure a firm installation. The cross-section of the snap-fit ​​part is "round at the top and round at the bottom", which facilitates positioning and direction adjustment during installation and improves assembly efficiency and accuracy.

[0023] Preferably, the mounting part and the snap-fit ​​part are provided with a plurality of mounting holes at even intervals, and the frame, the bottom plate and the cover plate are each provided with a plurality of positioning holes that cooperate with the mounting holes.

[0024] By adopting the above technical solution, the mounting holes opened in the support column mounting part and the snap-fit ​​part, in conjunction with the positioning holes opened in the frame, bottom plate and cover plate, can achieve more precise and stable installation and positioning of the support column and the box body, thereby enhancing the stability and vibration resistance of the entire vibration-resistant supercapacitor energy storage module structure.

[0025] Preferably, a pad is provided at the connection between the support column and the base plate and the cover plate.

[0026] By adopting the above technical solution, pads are placed at the connection between the support column and the base plate and the cover plate, which can play a buffering role, effectively reduce vibration transmission, thereby further improving the vibration resistance of the energy storage module and improving the connection stability.

[0027] Preferably, the top of the double-sided clamping plate is provided with a cable routing groove.

[0028] By adopting the above technical solution, the vibration-resistant supercapacitor energy storage module includes a housing, a single-sided clamp and a double-sided clamp arranged in parallel within the housing, a supercapacitor cell fixed between the single-sided clamp and the double-sided clamp, and a support column fixed at both ends to the housing, passing through the double-sided clamp and abutting against the single-sided clamp. At the same time, a wiring groove is opened on the top of the double-sided clamp, which makes the wiring of the supercapacitor cell more orderly, avoids messy wiring from affecting the module performance, and improves the regularity and safety of the internal structure of the module.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The single-sided clamp and the double-sided clamp are arranged parallel to each other in the receiving cavity, and the supercapacitor cell is fixed between the single-sided clamp and the double-sided clamp. This can effectively fix the supercapacitor cell and reduce the shaking and displacement of the supercapacitor cell when subjected to vibration or impact.

[0031] 2. To prevent internal connections from becoming loose due to displacement of individual supercapacitor cells caused by shaking, thus ensuring electrical performance, improving the reliability and stability of the energy storage module, and meeting the needs of application scenarios with high stability requirements.

[0040] The technical solutions in the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0041] In practical applications, the voltage and capacity of a single supercapacitor cell are limited, and multiple cells are usually combined in series and parallel to form an energy storage module to meet the requirements of high power and high voltage. Traditional module packaging methods are relatively simple, such as placing multiple capacitor cells directly in a box and fixing them with glue, tape, or simple partitions. Although these methods are inexpensive, they have significant defects in mechanical performance. When the energy storage module is used in a vibration or shock environment (e.g., installed in a vehicle or mobile device), the internal capacitor cells are prone to shaking, displacement, or even collision due to a lack of effective support and fixation. This mechanical instability directly leads to two serious consequences: first, internal electrical connection points (such as solder joints and connecting pieces) may loosen or break due to repeated stress, affecting the electrical performance and reliability of the module; second, the capacitor cells themselves may be damaged by collisions, posing safety hazards. This application mainly adopts a scheme of reasonably arranging clamps and support columns to fix the capacitor cells, which achieves the effect of enhancing the vibration resistance of the supercapacitor energy storage module. The following is a further detailed description of this application.

[0042] refer to Figure 1 , Figure 2 and Figure 4 The vibration-resistant supercapacitor energy storage module provided in this application includes a housing 1, a fixing component 2, at least one supercapacitor cell 3, and multiple support columns 4. The single-sided clamping plate 21 and double-sided clamping plate 22 of the fixing component 2 are arranged parallel to each other in the receiving cavity 11 of the housing 1. Each two adjacent rows of supercapacitor cells 3 are defined as an energy storage group. Each energy storage group is provided with a corresponding support column 4. Each support column 4 is located between two rows of supercapacitor cells 3 in an energy storage group. The supercapacitor cells 3 are fixed between each single-sided clamping plate 21 and double-sided clamping plate 22. The two ends of the support column 4 are fixed to the housing 1 and pass through the double-sided clamping plate 22 and abut against the single-sided clamping plate 21. This structure makes the supercapacitor cells 3 stably fixed in the housing 1, effectively preventing them from shaking and shifting when subjected to vibration or impact, and improving the vibration resistance of the energy storage module.

[0043] refer to Figure 2 Specifically, the housing 1 includes a receiving cavity 11, a frame 12, a base plate 13, and a cover plate 14. The frame 12 and the base plate 13 are fixedly connected, and this fixed connection can be achieved using common methods such as welding or bolting. For example, in actual production, welding can be used to form a robust integral structure between the frame 12 and the base plate 13. The cover plate 14 is fixedly connected to the support column 4, making the entire housing 1 a closed space, better protecting the internal supercapacitor cells 3. The frame 12, base plate 13, and cover plate 14 can be made of metal, such as aluminum alloy. Aluminum alloy has advantages such as light weight, high strength, and corrosion resistance, which can reduce the overall weight while ensuring the strength of the housing 1.

[0044] refer to Figures 2-5 The fixing component 2 includes two single-sided clamps 21 and at least one double-sided clamp 22, which are spaced apart and parallel to each other within the receiving cavity 11. Each of the single-sided clamps 21 and double-sided clamps 22 has multiple limiting slots 23 on its opposite side to engage with the supercapacitor cell 3. The supercapacitor cell 3 is engaged with the limiting slots 23. The limiting slots 23 allow for precise positioning and fixing of the supercapacitor cell 3. The limiting slots 23 can be square, circular, or other shapes to accommodate supercapacitor cells 3 of different shapes. The single-sided clamps 21 and double-sided clamps 22 are preferably made of reinforced nylon as insulation material, effectively isolating the supercapacitor cell 3 from contact with the metal housing 1. Their low density reduces overall weight, while the high strength of the reinforced nylon material effectively enhances the product's vibration resistance.

[0045] refer to Figures 2-6To facilitate series connection of capacitors, the limiting slot 23 can be further divided into a positive terminal slot 231 and a negative terminal slot 232. Two limiting slots 23 located in the middle of the double-sided clamping plate 22 are interconnected and are used to accommodate the positive and negative electrodes of two supercapacitors electrically connected via the first connecting piece 5, thus simplifying the internal electrical connection layout. Each pair of supercapacitor cells 3 located in the middle of the double-sided clamping plate 22 and the single-sided clamping plate 21 are electrically connected via the first connecting piece 5. Supercapacitor cells 3 located at both ends of the double-sided clamping plate 22 are electrically connected via the second connecting piece 6. Both the first connecting piece 5 and the second connecting piece 6 are fixedly connected within the limiting slot 23. The first connecting piece 5 and the second connecting piece 6 can be made of copper, which has good conductivity and ensures stable electrical connection between the supercapacitor cells 3.

[0046] refer to Figure 2 , Figure 5 and Figure 7 The support column 4 is fixed to the box body 1 at both ends. The support column 4 passes through the double-sided clamping plate 22 and abuts against the single-sided clamping plate 21 at both ends. The support column 4 includes a mounting part 41 and a snap-fit ​​part 42. Both the single-sided clamping plate 21 and the double-sided clamping plate 22 are provided with fixing holes 24. The support column 4 passes through the fixing holes 24 through the mounting part 41 and is fixed by the snap-fit ​​part 42.

[0047] refer to Figure 2 and Figure 7 The support column 4 has a cross-section comprising a square portion and a circular portion. The fixing hole 24 is a non-circular hole adapted to the square portion, so that when the support column 4 passes through the fixing hole 24, the rotation of the support column 4 is restricted by the cooperation between the square portion and the non-circular hole. Furthermore, the circular portion abuts against the surface of the two adjacent rows of supercapacitor cells 3 to support the supercapacitor cells 3. Specifically, the cross-section of the snap-fit ​​portion 42 is "round at the top and round at the bottom". The "round at the top and round at the bottom" cross-section design of the snap-fit ​​portion 42 has unique assembly advantages. When its upper square contour cooperates with the fixing hole 24, it can prevent the support column from rotating unexpectedly during the fastening process, playing a role in anti-rotation positioning. Its lower circular contour facilitates alignment and guidance during initial insertion, thereby comprehensively improving the speed and accuracy of installation. This special shape design can more easily realize the installation and fixation between the support column 4 and the clamping plate, while also ensuring a certain degree of stability.

[0048] The mounting section 41 and the snap-fit ​​section 42 are provided with multiple mounting holes 43 evenly spaced apart. The frame 12, the base plate 13, and the cover plate 14 are all provided with multiple positioning holes 15 that mate with the mounting holes 43. The support column 4 is aligned with the positioning holes 15 of the box 1 through the mounting holes 43 at both ends, and is detachably fixed by bolts passing through it, thereby facilitating the maintenance and disassembly of the module. By passing bolts through the mounting holes 43 and the positioning holes 15, the support column 4 can be firmly connected to the box 1. A pad 7 is provided at the connection between the support column 4 and the base plate 13 and the cover plate 14. The pad 7 can be made of rubber. Rubber has good elasticity and can play a buffering role, further enhancing the vibration resistance of the energy storage module.

[0049] refer to Figure 6 The top of the double-sided clamp 22 is provided with a wiring groove 221. The wiring groove 221 can facilitate the wiring between the supercapacitor cells 3, making the wires neat and orderly, and avoiding the wires from being messy and affecting the performance of the energy storage module.

[0050] The implementation principle of a vibration-resistant supercapacitor energy storage module according to this application embodiment is as follows: By rationally designing the structure of the housing 1, fixing component 2, and support column 4, the supercapacitor cell 3 is stably fixed inside the housing 1. The limiting slots 23 on the single-sided clamping plate 21 and double-sided clamping plate 22 precisely position and fix the supercapacitor cell 3. The support column 4 passes through the clamping plate and connects to the housing 1, enhancing the overall structural stability. Simultaneously, the rubber pad 7 provides a buffering effect, effectively reducing the impact of vibration and shock on the supercapacitor cell 3, improving the vibration resistance of the energy storage module, and ensuring the reliability and stability of the energy storage module.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
