[0039] The utility model is further illustrated in detail below in combination with the embodiments.

[0040] Embodiment of the super capacitor module of the utility model:

[0041] As shown in Figure 2 , Figure 3 , the super capacitor module comprises an insulating cover plate 1, an insulating bottom plate 2 and each super capacitor monomer 200 arranged between the insulating cover plate 1 and the insulating bottom plate 2, the insulating cover plate 1 and the insulating bottom plate 2 are both insulating materials, and the super capacitor monomer 200 is multiple and arranged in multiple rows. The super capacitor monomer 200 is provided with electrodes 201 at the upper and lower ends, one end is a positive electrode, and the other end is a negative electrode, each super capacitor monomer 200 is connected in series or parallel through a conductive row, and the super capacitor monomer 200 is fixed with the conductive row at the upper and lower ends. The conductive row is a copper row, there are multiple conductive rows, each conductive row comprises a connecting conductive row 7 connecting the same end of two adjacent super capacitor monomers 200 and a lead-out conductive row for connecting with an external circuit, the lead-out conductive row is two, which are a positive electrode lead-out conductive row 5 and a negative electrode lead-out conductive row 6, one end of the positive electrode lead-out conductive row 5 is fixedly connected with the lower end electrode of the corresponding super capacitor monomer, and the other end is connected with an external circuit as a module positive electrode, one end of the negative electrode lead-out conductive row 6 is fixedly connected with the upper end electrode of the corresponding super capacitor monomer, and the other end is connected with an external circuit as a module negative electrode. The connecting conductive row 7 is a rectangular sheet body, each connecting conductive row 7 is of the same specification, and the two ends of the length direction of the connecting conductive row 7 are fixedly connected with the same side end electrode 201 of the corresponding two adjacent super capacitor monomers 200 respectively, so as to connect each super capacitor monomer 200 in series and parallel into a group through each connecting conductive row 7.

[0042] The insulating cover plate 1 and the insulating bottom plate 2 are arranged in an up-down manner, and each super capacitor cell 200 and the conductive row are arranged between the insulating cover plate 1 and the insulating bottom plate 2. The bottom surface of the insulating cover plate 1 is opposite to the top surface of the insulating bottom plate 2. The bottom surface of the insulating cover plate 1 is the lower side surface thereof, and the top surface thereof is the upper side surface thereof. The top surface of the insulating bottom plate 2 is the upper side surface thereof, and the bottom surface thereof is the lower side surface thereof. The bottom surface of the insulating cover plate 1 and the top surface of the insulating bottom plate 2 are each provided with a conductive row avoiding slot. The slot opening of the conductive row avoiding slot faces the side where the super capacitor cell 200 is located. The slot opening of the conductive row avoiding slot on the insulating cover plate 1 faces downward to avoid the conductive row fixed at the upper end of each super capacitor cell 200. The slot opening of the conductive row avoiding slot on the insulating bottom plate 2 faces upward to avoid the conductive row fixed at the lower end of each super capacitor cell 200. When the insulating bottom plate 2 and the insulating cover plate 1 are installed on each super capacitor cell 200 connected in series by the conductive row, the conductive row fixed at the corresponding end of the super capacitor cell 200 is installed in the conductive row avoiding slot through the slot opening of the corresponding conductive row avoiding slot. The conductive row avoiding slot provides installation space for the conductive row. In this way, the thickness dimension of the relatively thick insulating cover plate and the insulating bottom plate can be compatible with the thickness dimension of the conductive row. The height of the super capacitor module in the up-down direction can be reduced, which is conducive to reducing the volume of the module. In the embodiment, the conductive row avoiding slots are arranged on both the insulating cover plate and the insulating bottom plate. In other embodiments, the conductive row avoiding slots can be arranged only on the insulating cover plate to reduce the influence of the upper conductive row on the height of the module, or the conductive row avoiding slots can be arranged only on the insulating bottom plate to reduce the influence of the lower conductive row on the height of the module.

[0043] The height direction of the super capacitor module is the up-down direction. The thickness direction of the insulating cover plate 1 and the insulating bottom plate 2 is the up-down direction. The thickness direction of the part of the lead-out conductive row fixed on the electrode and the thickness direction of the connecting conductive row 7 are the up-down direction. The insulating cover plate 1 and the insulating bottom plate 2 have a certain structural strength and also have an insulation protection function. The negative lead-out conductive row 6 and the connecting conductive row 7 fixed at the upper end of the super capacitor cell 200 constitute the upper conductive row of the super capacitor module. There are multiple upper conductive rows, and correspondingly, the conductive row avoiding slots on the bottom surface of the insulating cover plate 1 are also multiple. The positive lead-out conductive row 5 and the connecting conductive row fixed at the upper end of the super capacitor cell 200 constitute the lower conductive row of the super capacitor module. There are multiple lower conductive rows, and correspondingly, the conductive row avoiding slots on the top surface of the insulating bottom plate 2 are also multiple. The conductive row avoiding slots correspond to the conductive rows one by one. Each conductive row has a corresponding conductive row avoiding slot.

[0044] The matching form of the insulating cover plate 1 and the upper conductive row is the same as the matching form of the insulating bottom plate 2 and the lower conductive row. The matching form of the insulating cover plate 1 and the upper conductive row is combined with the matching form of the insulating bottom plate 2 and the lower conductive row. Figure 4 and Figure 5The structure of the insulating cover plate 1 is described in terms of the fitting form. The conductive row avoiding grooves 11 on the insulating cover plate 1 are adapted to fit the upper side conductive rows, each of which corresponds to one conductive row avoiding groove 11 for fixing the upper side conductive row on the upper end electrode 201 of the super capacitor cell 200, so that when the insulating cover plate 1 is installed, the upper side conductive row can enter the corresponding conductive row avoiding groove 11. The conductive row avoiding groove 11 is adapted to fit the corresponding upper side conductive row, the connecting conductive row 7 is a rectangular piece, and the part of the connecting conductive row 7 fixed on the electrode is also a rectangular piece. Correspondingly, the conductive row avoiding groove 11 is a rectangular groove, which is adapted to the shape and size of the corresponding conductive row. The conductive row can be embedded in the conductive row avoiding groove 11. The conductive row avoiding groove 11 has groove side walls for limiting the conductive row in the direction perpendicular to the thickness of the conductive row. The groove side walls of the rectangular groove can horizontally limit the conductive row in the front-back and left-right directions, thereby enhancing the stability and insulating the conductive rows.

[0045] The insulating cover plate 1 and the insulating bottom plate 2 can be made of epoxy resin, nylon or nylon + glass fiber. The capacitor equalization control circuit board 3 is installed on the upper side of the insulating cover plate 1. The capacitor equalization control circuit board 3 is provided with components for monitoring the voltage and temperature of the capacitor. The insulating cover plate 1 is provided with wire holes through which the capacitor voltage and temperature collection wire harness 4 passes, so that the capacitor voltage and temperature collection wire harness 4 is connected to the corresponding components. The corresponding components are connected to each connecting conductive row 7 through the capacitor voltage and temperature collection wire harness 4. The capacitor voltage and temperature collection wire harness 4 has branch lines 40 for connecting each connecting conductive row 7. The end of the branch line 40 is provided with a collection wire harness terminal 41. The collection wire harness terminal 41 is fixed to the connecting conductive row 7. The connecting conductive row 7 forms a conductive row connected to the collection wire harness. The bottom surface of the insulating cover plate 1 and the top surface of the insulating bottom plate 2 are also provided with wiring grooves in communication with the conductive row avoiding grooves on the corresponding surface. The capacitor voltage and temperature collection wire harness 4 is installed in the wiring groove.

[0046] For the insulating cover plate 1, the conductive row avoiding grooves 11 and the wiring grooves 12 are in communication, and the branch lines 40 are arranged in the wiring grooves 12. The collection wire harness terminals 41 at the ends of the branch lines 40 extend into the conductive row avoiding grooves 11 and are connected to the connecting conductive rows 7. The wiring grooves 12 are used for wiring, and the thicknesses of the insulating cover plate 1 and the insulating bottom plate 2 provide wire harness wiring space. The wiring grooves 12 provide a wiring path for the low-voltage wire harness, save vertical space, and can protect the low-voltage wire harness from being damaged by other metal parts.

[0047] The acquisition harness terminal 41 is a terminal arranged at the end of the branch line 40 of the acquisition harness for connecting the corresponding conductive strip. Figure 6 The connection conductive strip 7 is provided with a terminal connection hole 72 for fixedly connecting the acquisition harness terminal 41. The upper acquisition harness terminal 41 extends between the upper connection conductive strip 7 and the insulating cover plate 1, and the lower acquisition harness terminal 41 extends between the lower connection conductive strip 7 and the insulating bottom plate 2. The acquisition harness terminal 41 is an OT terminal fixedly connected to the terminal connection hole 72 by a bolt. The side hole of the terminal connection hole 72 on the connection conductive strip 7 away from the supercapacitor cell 200 is provided with a clearance groove. The clearance groove is an open groove, and the clearance groove is adapted to the extension of the acquisition harness terminal 41 to avoid the acquisition harness terminal 41 occupying additional space in the up-down direction.

[0048] In order to avoid the bolt for fixedly connecting the acquisition harness terminal 41 and the connection conductive strip 7, the terminal clearance groove 13 corresponding to the position of the terminal connection hole 72 on the connection conductive strip 7 is arranged on the conductive strip clearance groove 11. The terminal clearance groove 13 is located at the groove bottom of the conductive strip clearance groove 11 and corresponds to the position of the acquisition harness terminal 41. The terminal clearance groove 13 can avoid the head of the bolt and avoid the bolt occupying additional height. The terminal clearance groove 13 can insulate and limit the position of the acquisition harness terminal 41. In other embodiments, the acquisition harness terminal can also be welded and fixed with the conductive strip, and the terminal connection hole is not arranged. In other embodiments, the terminal clearance groove can also not be arranged when the depth of the conductive strip clearance groove is sufficient.

[0049] The insulating bottom plate 2 is the same as the insulating cover plate 1. The insulating bottom plate 2 is provided with a conductive strip clearance groove for the lower conductive strip to enter, a wiring groove for arranging the corresponding harness, and a terminal clearance groove for avoiding the fixed bolt of the corresponding acquisition harness terminal.

[0050] The electrode 201 of the supercapacitor cell 200 is a pole. The conductive strip is provided with a pole fixing hole 73. The pole is adapted to the pole fixing hole 73. The pole fixing hole 73 penetrates along the thickness direction of the conductive strip. The electrode 201 extends into the pole fixing hole 73. The conductive strip is fixed to the electrode 201 at the pole fixing hole 73 and forms a conductive connection by welding. The two ends of the connection conductive strip 7 in the length direction are respectively provided with the pole fixing hole 73 for the electrode 201 of the supercapacitor cell 200 to extend into. The pole fixing hole 73 cooperates with the electrode 201 for welding, which can reduce the height in the up-down direction of the module. In other embodiments, the electrode can also be a threaded stud, and the conductive strip is fixed to the electrode by a nut.

[0051] The depth of the conductive bar avoiding slot 11 is the same as the thickness of the conductive bar, and the thickness of the conductive bar is the same as the height of the pole. The edge of the slot of the conductive bar avoiding slot 11 is attached to the end surface of the supercapacitor cell 200 located at the periphery of the pole. The structure is compact, which is conducive to ensuring the thickness of the cover plate and the bottom plate, and avoiding increasing the volume of the module. In other embodiments, the edge of the slot of the conductive bar avoiding slot can be spaced apart from the end surface of the supercapacitor cell located at the periphery of the pole, and a part of the conductive bar in the thickness direction is located in the conductive bar avoiding slot.

[0052] The insulating cover plate 1 is provided with a connecting structure fixedly connected with the conductive bar fixedly connected with one end of the insulating cover plate 1 adjacent to the supercapacitor cell 200. The insulating bottom plate 2 is provided with a connecting structure fixedly connected with the conductive bar fixedly connected with one end of the insulating bottom plate 2 adjacent to the supercapacitor cell 200. The upper end of the supercapacitor cell 200 is the end adjacent to the insulating cover plate 1. The connecting conductive bar 7 fixedly connected with the upper end electrode of the supercapacitor cell 200 is fixedly connected with the insulating cover plate 1. The lower end of the supercapacitor cell 200 is the end adjacent to the insulating bottom plate 2. The connecting conductive bar 7 fixedly connected with the lower end electrode of the supercapacitor cell 200 is fixedly connected with the insulating bottom plate 2. The insulating cover plate 1 and the insulating bottom plate 2 are fixed together by fixing the respective connecting conductive bars 7 to fix the supercapacitor cells 200 together.

[0053] Since the supercapacitor cells 200 are connected in series and parallel by the connecting conductive bars 7, the connecting conductive bars 7 are fixedly connected with the supercapacitor cells 200. Therefore, the insulating cover plate 1 and the insulating bottom plate 2 are fixedly connected by the connecting conductive bars 7. The insulating cover plate 1 fixes the connecting conductive bars 7 at the upper end together, and the insulating bottom plate 2 fixes the connecting conductive bars 7 at the lower end together. By fixing the connecting conductive bars 7 together, the supercapacitor cells 200 are fixed together. Such a fixing structure is relatively simple. The insulating cover plate 1 and the insulating bottom plate 2 are fixed by the conductive bars, without the need for long bolts and other parts, which is conducive to reducing the weight of the supercapacitor module. In other embodiments, the insulating cover plate and the insulating bottom plate can be fixedly connected by long bolts and nuts. The insulating cover plate and the insulating bottom plate clamp and fix the conductive bars and the supercapacitor cells.

[0054] In this embodiment, all the connecting conductive bars 7 located at the upper end of the supercapacitor cell 200 are fixed with the insulating cover plate 1, and all the connecting conductive bars 7 located at the lower end of the supercapacitor cell 200 are fixed with the insulating bottom plate 2, to enhance stability. In other embodiments, a part of the connecting conductive bars can not be fixed with the insulating cover plate or the insulating bottom plate. In this embodiment, the insulating cover plate and the insulating bottom plate are fixedly connected only with the connecting conductive bars, and not with the positive electrode lead-out conductive bar and the negative electrode lead-out conductive bar. In other embodiments, the positive electrode lead-out conductive bar and the negative electrode lead-out conductive bar can be fixedly connected with the insulating cover plate and the insulating bottom plate, respectively.

[0055] In this embodiment, the insulation cover plate 1 and the insulation bottom plate 2 are fixedly connected to the corresponding connecting conductive strips 7 in a clamping manner. Figure 4 、 Figure 6 、 Figure 7 The connecting structure on the insulation cover plate 1 and the connecting structure on the insulation bottom plate 2 are both buckles 8. Correspondingly, each connecting conductive strip 7 is provided with a clamping matching part for clamping the buckle 8 so as to clamp and fix the insulation cover plate 1 and the insulation bottom plate 2 to the corresponding connecting conductive strip 7. The clamping structure is used for fixation, which is convenient for assembly operation. The buckle 8 can be made of plastic to reduce the weight of the module and save cost. In other embodiments, bolt holes can be provided on the insulation cover plate and the insulation bottom plate, the bolt holes are provided with bolts, and threaded holes are provided on the conductive strips, and the bolts constitute the connecting structure to fix the insulation cover plate and the insulation bottom plate to the corresponding conductive strips by the bolts.

[0056] The buckle 8 includes a fixing part 81 for being fixed on the insulation cover plate 1 or the insulation bottom plate 2 and a clamping part 82 for clamping matching with the connecting conductive strip 7. The clamping part 82 has two clamping hooks which can be elastically deformed. The connecting conductive strip 7 is provided with a clamping matching hole 71 which constitutes the clamping matching part. The clamping part 82 of the buckle 8 passes through the clamping matching hole 71 from one side of the conductive strip and clamps and matches with the other side surface of the conductive strip. The clamping hooks of the clamping part 82 are closed when they are inserted into the clamping matching hole 71, and are restored after being taken out of the clamping matching hole 71 and are blocked on the corresponding side surface of the connecting conductive strip 7. The clamping matching hole 71 and the buckle 8 form clamping matching, which is simple in structure and reliable in clamping. The buckle 8 is fixed on the groove bottom of the conductive strip avoiding groove 11 to adapt to the position of the clamping matching hole 71 on the connecting conductive strip 7. In other embodiments, the buckle can also have two clamping hooks which are oppositely arranged and clamped on the two side edges in the width direction of the conductive strip.

[0057] The fixing part 81 of the buckle 8 is in a columnar structure. The end surface of the fixing part 81 which is away from the clamping part 82 is adhesively fixed on the groove bottom surface of the corresponding conductive strip avoiding groove 11 of the insulation cover plate 1 or the insulation bottom plate 2, which is simple in structure and convenient for manufacturing. In other embodiments, the buckle can be integrally formed with the insulation cover plate or the insulation bottom plate.

[0058] The clamping matching hole 71 on the connecting conductive strip 7 is provided with an avoiding groove 711 at the hole opening for avoiding the fixing part 81 of the buckle 8. The hole opening of the clamping matching hole 71 which is provided with the avoiding groove 711 is the hole opening for clamping the buckle 8. The buckle 8 is inserted from one side hole opening of the clamping matching hole 71 and taken out from the other side hole opening. The fixing part 81 of the buckle 8 can enter the avoiding groove 711 at the hole opening of the clamping matching hole 71 and be attached to the groove bottom of the avoiding groove 711, so that the insulation cover plate 1 and the insulation bottom plate 2 can be attached to the corresponding conductive strip, which is beneficial to reliable fixation and can reduce the height of the module in the up-down direction.

[0059] The relief groove 711 at the aperture of the clamping fitting hole 71 is adapted to the fixing part 81 of the buckle 8, and the relief groove 711 is provided with a limiting groove wall for limiting the fixing part 81 of the buckle 8 in the radial direction of the clamping fitting hole 71, so as to ensure the position of the insulating cover plate 1 and the insulating bottom plate 2 perpendicular to the up-down direction, and enhance the stability.

[0060] The terminal connecting hole 72 on the connecting conductive bar 7 is symmetrically arranged with the clamping fitting hole 71 in the width direction of the connecting conductive bar 7, that is, the relief groove at the aperture of the terminal connecting hole 72 is consistent with the relief groove 711 at the aperture of the clamping fitting hole 71, both of which are open grooves, and the opening of the open groove penetrates through the edge in the width direction of the connecting conductive bar 7. The terminal connecting hole 72 and the clamping fitting hole 71 are arranged in a symmetrical structure, so that the connecting conductive bar 7 and the super capacitor cell 200 can be fixed without distinguishing the direction, which is convenient for operation.

[0061] The clamping fitting hole 71 of the connecting conductive bar 7, that is, the part of the connecting conductive bar 7 for fixing the connecting insulating bottom plate 2 or the insulating cover plate 1, corresponds to the position of the gap between the two adjacent super capacitor cells 200. The terminal connecting hole 72 and the clamping fitting hole 71 are arranged at the middle position in the length direction of the connecting conductive bar 7, and the terminal connecting hole 72 and the clamping fitting hole 71 both correspond to the gap between the two adjacent super capacitor cells 200. Since the super capacitor cell 200 is a cylinder, a gap is formed between the outer circumferential surfaces of the two adjacent super capacitor cells 200, so that the part of the connecting conductive bar 7 for fixing the connecting insulating cover plate 1 or the insulating bottom plate 2 corresponds to the gap, and the space at the gap is used to arrange the connecting structure, so as to avoid increasing the size of the connecting conductive bar 7.

[0062] The super capacitor module has the advantages of reduced module size, weight and cost, simple and reliable structure, and is beneficial to application in the field of portable automobile starting power supply.
