Description

Technical Field

[0001] The utility model belongs to the technical field of capacitors, and specifically relates to a high-voltage supercapacitor energy storage component. Background Art

[0002] Due to its high power density, long cycle life, and fast charge and discharge capabilities, supercapacitors have occupied an important position in the modern energy storage field. However, the operating voltage of a single supercapacitor is relatively low, usually between 1.7V and 3V. This low voltage limits the direct use of supercapacitors in practical applications. Therefore, it is necessary to increase the overall voltage through series and parallel connections. Series connection can increase the overall voltage, while parallel connection can increase the capacitance and power output capabilities. In this way, the voltage range of the supercapacitor energy storage module can be increased from 10V to 110V or even higher to meet the requirements of various industrial and commercial applications.

[0003] Capacitor monomers are connected in series and parallel to form an energy storage module and are stored in the energy storage component. The energy storage component limits and fixes the energy storage module to ensure that the energy storage module can operate in a stable state. Conventional energy storage components are integrally formed by a metal skeleton to withstand external impacts, and a large number of rib plates are used to limit the capacitor monomers to ensure the safe operation of the capacitors. However, this structure results in a heavy energy storage component and cannot meet the current lightweight requirements. Moreover, the flexibility of capacitor arrangement in this structure of the energy storage component is not high, and it is difficult to adjust for different application scenarios. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a high-voltage supercapacitor energy storage component to solve the problems raised in the above-mentioned prior art.

[0005] A high-voltage supercapacitor energy storage component is provided, including:

[0006] An overall machine management module, which includes a top plate and a bottom plate;

[0007] A number of single-layer management modules, each single-layer management module includes two insulating fixing plates, a number of single-layer connecting columns, and a number of anti-misalignment screws. A number of the single-layer connecting columns are clamped between the two insulating fixing plates, and the anti-misalignment screws penetrate through the insulating fixing plates and are threadedly connected to the ends of the single-layer connecting columns. The anti-misalignment screws between adjacent two single-layer management modules can be mutually engaged;

[0008] A number of connecting rods, a number of the single-layer management modules are stacked in sequence and clamped between the top plate and the bottom plate. After a number of the connecting rods penetrate through a number of the single-layer management modules in sequence, both ends of the connecting rods are detachably connected to the top plate and the bottom plate respectively.

[0009] Further, the anti-displacement screw includes a first screw and a second screw. A groove is formed in the head of the first screw, and the head of the second screw can be engaged with the groove of the first screw. After the first screw and the second screw are engaged, the lateral degrees of freedom of each single-layer management module are restricted under the limitation of the groove, so that a plurality of single-layer management modules are connected to form an integral body, reducing the lateral pressure on the connecting rod and effectively preventing the connecting rod from deforming under force.

[0010] Further, a plurality of the single-layer management modules are stacked in sequence to form a hollow columnar structure as a whole. The hollow columnar structure has a large sectional moment of inertia, and thus has high stability, which is beneficial to forming a stacked structural form.

[0011] Further, a plurality of positioning grooves for cooperating with the capacitor monomers are formed in the insulating fixing plate along the length direction. When two insulating fixing plates clamp the capacitor monomers in the middle, the two ends of the capacitor monomers are engaged in the positioning grooves, so that the capacitor monomers will not shift, playing a role in stabilizing the capacitor monomers.

[0012] Further, a plurality of same-layer connecting pieces are further included. The plurality of same-layer connecting pieces are used to sequentially connect the corresponding electrodes of several capacitors in a single single-layer management module to form a series structure, and the same-layer connecting pieces are fixedly welded to the electrodes of the capacitors.

[0013] Further, a plurality of staggered-layer connecting pieces are further included. The staggered-layer connecting pieces are used to connect the corresponding electrodes of the capacitors in two adjacent single-layer management modules. Using the staggered-layer connecting pieces as wires for upper and lower layer series and parallel connections can effectively enhance the connection strength of the energy storage components and the current-carrying strength of the capacitor energy storage components.

[0014] Further, the staggered-layer connecting piece includes two commutation connecting pieces and a staggered-layer connecting piece. One ends of the two commutation connecting pieces are respectively fixedly welded to the corresponding capacitor electrodes in two adjacent single-layer management modules, and the other ends of the two commutation connecting pieces are detachably connected through the staggered-layer connecting piece. The commutation connecting pieces are used to lead out from between the layers of the single-layer management module to the outside, and the staggered-layer connecting piece is used to connect the two led-out commutation connecting pieces.

[0015] Further, connection piece fitting grooves are further formed in the insulating fixing plate at corresponding positions of each positioning groove. The connection piece fitting grooves are used to assemble the same-layer connecting pieces and enable the staggered-layer connecting pieces to avoid interference with the insulating fixing plate and be assembled with the insulating fixing plate.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. The energy storage component consists of individual separable whole-machine management modules and single-layer management modules. When the capacitor operates normally, the single-layer management modules are fixedly connected through the top plate, bottom plate, and connecting rod to ensure the operation stability of the capacitor. When it is necessary to disassemble the single-layer management module, only need to remove the top plate, and then slide the single-layer management module along the connecting rod to take it out. The advantage of this structure is that it can prevent the capacitor component from shifting in the horizontal direction. At the same time, during loading and unloading, only the cooperation relationship between the connecting rod and the bottom plate and top plate needs to be operated, without the need to refix each layer of module to the adjacent module.

[0018] 2. Inside each single-layer management module, the structure is strengthened through several single-layer connecting columns, which can enhance the support strength and structural stability of the single-layer management module, enabling the single-layer management module to have a stronger load-bearing capacity.

[0019] 3. In addition to fixing and limiting the single-layer management module through the connecting rod, the single-layer management modules are also limited by anti-displacement screws, which can effectively prevent the single-layer management modules from shifting, avoiding deformation of the connecting columns due to excessive local loads caused by the shift of a single single-layer management module. Since the anti-displacement screws can be stacked in a mutually engaging manner, there is no need to fix the adjacent two single-layer management modules, which can improve the loading and unloading efficiency of the energy storage component.

In addition, it can also be understood that although the efforts made in this development process may be complex and time-consuming, for those of ordinary skill in the art related to the content disclosed in the present application, some design, manufacturing or production changes made on the basis of the technical content disclosed in the present application are only conventional technical means and should not be understood that the content disclosed in the present application is insufficient.

[0030] However, there will be cases where unnecessary detailed descriptions are omitted. For example, there are cases where detailed descriptions of well-known matters are omitted and repeated descriptions of actually identical structures are omitted. This is to avoid the following description from becoming unnecessarily long and to facilitate the understanding of those skilled in the art. In addition, the accompanying drawings and the following description are provided for those skilled in the art to fully understand the present application and are not intended to limit the subject matter recited in the claims.

[0031] Please refer to Figures 1-6As shown in the figure, in an embodiment of the present utility model, a high-voltage supercapacitor energy storage component includes a whole-machine management module 1, a plurality of single-layer management modules 2, and a plurality of connecting rods 3. The whole-machine management module 1 includes a top plate 11 and a bottom plate 12. The single-layer management module 2 includes two insulating fixing plates 21, a plurality of single-layer connecting columns 22, and a plurality of anti-misalignment screws 23. The plurality of single-layer connecting columns 22 are clamped between the two insulating fixing plates 21. The anti-misalignment screws 23 penetrate through the insulating fixing plates 21 and are threadedly connected to the ends of the single-layer connecting columns 22. The anti-misalignment screws 23 between adjacent two single-layer management modules 2 can be engaged with each other. After the plurality of single-layer management modules 2 are stacked in sequence, they are clamped between the top plate 11 and the bottom plate 12. After the plurality of connecting rods 3 penetrate through the plurality of single-layer management modules 2 in sequence, the two ends of the connecting rod 3 are detachably connected to the top plate 11 and the bottom plate 12 respectively.

[0032] After the plurality of single-layer management modules 2 are stacked, both ends are fixed and limited by the whole-machine management module 1. Specifically, the top plate 11 and the bottom plate 12 clamp the stacked single-layer management modules 2, and the plurality of connecting rods 3 penetrate through the top plate 11, the plurality of single-layer management modules 2, and the bottom plate 12 in sequence. Then, the two ends of the connecting rod 3 are fixed to the top plate 11 and the bottom plate 12 respectively by bolts. The single-layer connecting columns 22 are located between the two insulating fixing plates 21 for support to prevent the load of the insulating fixing plates 21 from being directly applied to the capacitors. The single-layer connecting columns 22 and the insulating fixing plates 21 are threadedly fixed by the anti-misalignment screws 23, so that the single-layer management module 2 forms a stable whole. When the plurality of single-layer management modules 2 are stacked, the anti-misalignment screws 23 between adjacent single-layer management modules 2 are engaged with each other to prevent the single-layer management modules 2 from being misaligned and offset from each other, and improve the overall stability of the energy storage component.

[0033] The anti-misalignment screw 23 includes a first screw 231 and a second screw 232. The first screw 231 and the second screw 232 are respectively driven into the single-layer management module 2 from both ends. When stacking, the head of the second screw 232 on the single-layer management module 2 can be engaged with the groove of the first screw 231 on another single-layer management module 2, thereby restricting the radial freedom between the two single-layer management modules 2 and ensuring that the single-layer management modules 2 do not shift relative to each other. The stability of the energy storage component is improved through the cooperation of the single-layer connecting columns 22 and the anti-misalignment screws 23, meeting the requirements of product lightweight. The anti-misalignment design between layers can improve the maintainability of the product, facilitate product disassembly, and improve the product assembly efficiency.

[0034] After the plurality of single-layer management modules 2 are stacked in sequence, the whole forms a hollow columnar structure. This columnar body can adopt a fully enclosed or partially enclosed form to improve the stability of the energy storage component by increasing the sectional moment of inertia.

[0035] The insulating fixing plate 21 is provided with a plurality of positioning grooves 211 along the length direction for cooperating with the capacitor monomers. The positioning grooves 211 are used to cooperate with the capacitor monomers so that both ends of the capacitor monomers are limited and fixed through the positioning grooves 211, improving the use stability of the capacitors.

[0036] Furthermore, the energy storage assembly further includes a plurality of same-layer connecting pieces 4. The plurality of same-layer connecting pieces 4 are used to sequentially connect the corresponding electrodes of a plurality of capacitors in a single single-layer management module 2 to form a series structure. The same-layer connecting pieces 4 are fixedly welded to the electrodes of the capacitors. The capacitors on the single-layer management module 2 are connected by using rigid connecting pieces to form a series structure, and the capacitor monomers and the connecting pieces are fixedly connected by welding.

[0037] The energy storage assembly further includes a plurality of staggered-layer connecting pieces 5. The staggered-layer connecting pieces 5 are used to connect the corresponding electrodes of the capacitors in two adjacent single-layer management modules 2, serving as a wire to form a series-parallel structure for the upper and lower single-layer management modules 2.

[0038] Using such metal connecting pieces as the same-layer connecting pieces 4 and the staggered-layer connecting pieces 5 to replace the wires for series-parallel connection of the supercapacitors can effectively enhance the connection strength of the energy storage assembly and the current-carrying (maximum current-carrying capacity) strength of the capacitor energy storage assembly.

[0039] Specifically, the staggered-layer connecting piece 5 includes two commutation connecting pieces 51 and one staggered-layer connecting piece 52. The commutation connecting piece 51 is integrally in an "L" shape structure. After the lead-out end is connected to the electrode of the capacitor, it is led out through a fold angle, and the other led-out end is a connection end connected to the staggered-layer connecting piece 52. The staggered-layer connecting piece 52 connects the commutation connecting pieces 51 led out from the upper and lower single-layer management modules 2 and forms a series structure or a parallel structure for the two single-layer management modules 2 as required.

[0040] The commutation connecting piece 51 and the staggered-layer connecting piece 52 can be connected by screws. Two threaded hole positions are provided on the connection end of the commutation connecting piece 51. When a plurality of single-layer management modules 2 are in parallel connection, the two threaded hole positions on the commutation connecting piece 51 need to be respectively connected to two staggered-layer connecting pieces 52.

[0041] The insulating fixing plate 21 is further provided with connecting piece fitting grooves 212 at corresponding positions of each positioning groove 211. The connecting piece fitting grooves 212 are used to assemble the same-layer connecting pieces 4 and enable the staggered-layer connecting pieces 5 to avoid interference with the insulating fixing plate 21 and be assembled with the insulating fixing plate 21.

[0042] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and embodiments having the same constitution in essence as the technical idea and achieving the same effects within the scope of the technical solution of this application are all included in the technical scope of this application. In addition, within the scope not departing from the gist of this application, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways constructed by combining some of the constituent elements in the embodiments are also included in the scope of this application.
