Description

Technical Field

[0001] The utility model relates to the technical field of new energy, in particular to a novel super capacitor module. Background Art

[0002] Supercapacitors are a new type of energy storage device between traditional capacitors and rechargeable batteries, with a capacity of several hundred to thousands of farads. Compared with traditional capacitors, they have larger capacity, specific energy or energy density, wider operating temperature range and extremely long service life, while compared with batteries, they have higher specific power and are environmentally friendly. In recent years, the supercapacitor industry has developed rapidly, and therefore, the performance requirements for supercapacitor products are getting higher and higher.

[0003] At present, when manufacturing a supercapacitor module including multiple supercapacitor cells, since the supercapacitor cells cannot be guaranteed to be on the same plane during the process of welding into a module, some supercapacitor cells will be squeezed and some supercapacitor cells will be suspended in the air during the current assembly process, that is, the supercapacitor cells cannot be placed stably, which in turn causes the supercapacitor module to be easily shaken off (i.e., fall off) when it is vibrated by external force, resulting in the problem of the module being scrapped.

[0004] Therefore, there is an urgent need to develop a technology that can solve the above technical problems. Utility Model Content

[0007] An upper cover is arranged on the top of the lower box body;

[0008] The edges of the upper cover are surrounded by a first convex edge;

[0009] The lower box is a hollow box with an open top;

[0010] A second convex edge is circumferentially arranged on the top of the lower box body at a position corresponding to the first convex edge;

[0011] A receiving cavity for placing the supercapacitor module is formed between the upper cover and the lower box body;

[0012] A supercapacitor module, comprising a plurality of vertically distributed capacitor cells;

[0013] A flexible pressing mechanism is provided at the bottom of the accommodating cavity;

[0045] In the present invention, in a specific implementation, a busbar 2-0 is provided on the top of the capacitor monomer 2-1.

[0046] The top of the busbar 2 - 0 is in close contact with the bottom surface of the top panel 102 of the upper cover 1 ;

[0048] In a specific implementation, the positive electrode connecting piece and the negative electrode connecting piece on the top of the capacitor monomer 2-1 are respectively connected (specifically welded) to the positive electrode welding point and the negative electrode welding point on the busbar 2-0.

[0051] The top of the horizontally distributed cover plate 2-5 is provided with (specifically, covered with) a bracket 2-3;

[0052] On the bracket 2-3, a plurality of capacitor accommodating cavities 30 are distributed at equal intervals;

[0053] Each capacitor accommodating cavity 30 includes two parts, a capacitor insertion hole 31 and a mechanism installation cavity section 32, which are distributed up and down;

[0054] The bottom of each mechanism installation cavity section 32 is provided with horizontally distributed guide seats 2-6;

[0055] A vertically distributed, hollow intermediate shaft guide cylinder 2-61 is provided at the top center of the guide seat 2-6;

[0056] The top of the intermediate shaft guide cylinder 2-61 is open, and the lower end of the intermediate shaft 2-8 distributed vertically is inserted into the intermediate shaft guide cylinder 2-61;

[0057] A plurality of vertically distributed, hollow peripheral shaft guide cylinders 2-62 are provided on the top of the guide seat 2-6;

[0058] The top of each peripheral shaft guide cylinder 2-62 is open, and the lower end of the vertically distributed peripheral shaft 2-4 is inserted into each intermediate shaft guide cylinder 2-61;

[0059] The tops of the intermediate shaft 2-8 and the peripheral shaft 2-4 are provided with horizontally distributed pressing plates 2-2;

[0060] The outside of the intermediate shaft 2-8 and the peripheral shaft 2-4 are respectively covered with spiral springs 2-7.

[0061] It should be noted that, for the utility model, the intermediate shaft guide cylinder 2-61 and the peripheral shaft guide cylinder 2-62 (both are cylindrical) on the guide seat 2-6 are respectively connected with the intermediate shaft 2-8 and the peripheral shaft 2-4 in a sliding fit (that is, they can be slidably connected up and down, and driven by the downward extrusion force applied from top to bottom by the capacitor monomer, the intermediate shaft 2-8 and the peripheral shaft 2-4 can slide in the corresponding guide cylinders and descend a certain distance).

[0062] In specific implementation, the bracket 2-3 is provided with a capacitor insertion hole 31 at a position corresponding to each pressing plate 2-2;

[0063] The capacitor insertion hole 31 is used to insert the lower end of a capacitor monomer 2-1;

[0065] The capacitor insertion hole 31 is circular in shape, and its diameter is smaller than the diameter of the circular pressing plate 2 - 2 .

[0066] Therefore, the pressing plate 2-2 is blocked by the structural portion of the bracket 2-3 around the capacitor insertion hole 31 and will not continue to move upward.

[0067] Furthermore, the center point of the capacitor insertion hole 31 and the center point of the pressing plate 2 - 2 are located on the same central axis.

[0068] In a specific implementation, a plurality of (for example, three) peripheral shafts 2-4 are distributed around the middle shaft 2-8 (ie, arranged in a circle);

[0069] It should be noted that, in the present invention, a plurality of peripheral shafts 2-4 are arranged in a circle relative to the pressure plate 2-2.

[0070] In a specific implementation, the center point of the intermediate shaft 2-8 and the center point of the pressure plate 2-2 are located on the same central axis, that is, the intermediate shaft 2-8 is located at the center of the pressure plate 2-2.

[0071] In specific implementation, the pressure plate 2-2 is pivotally connected to the upper ends of the peripheral shaft 2-4 and the intermediate shaft 2-8 (ie, the shell is rotatably connected). The specific structural design is as follows:

[0072] At the bottom of the pressing plate 2-2, at the position corresponding to each peripheral shaft 2-4 and the intermediate shaft 2-8, a hollow buckle 2-10 (the buckle 2-10 is a hollow structure) is respectively provided;

[0073] The top ends of the peripheral shaft 2-4 and the intermediate shaft 2-8 are provided with spherical protrusions 2-11 respectively;

[0074] Each protrusion 2-11 is located on the inner side of a buckle 2-10;

[0075] Furthermore, each buckle 2-10 includes three arc-shaped spring pieces 2-100 that are distributed around (the three spring pieces 2-100 are all bent inwards and are rotationally symmetrically distributed);

[0076] A cavity for placing the protrusion 2-11 is formed between the three spring pieces 2-100, and a limiting notch is formed between the bottoms of the three spring pieces 2-100;

[0077] The limiting notch is circular in shape, and its diameter is smaller than the diameter of the protrusion 2-11 (ie, the diameter size of the limiting notch when the protrusion has been placed in the cavity within the three spring pieces 2-100).

[0078] It should be noted that, for the present invention, the lower side of the pressure plate 2-2 is rotatably connected to the upper ends of the peripheral shaft 2-4 and the intermediate shaft 2-8.

[0079] In a specific implementation, the bracket 2-3 is fixedly arranged on the top of the cover plate 2-5.

[0080] In specific implementation, the bottom end of the spring 2-7 contacts the top end of the intermediate shaft guide cylinder 2-61 or the peripheral shaft guide cylinder 2-62;

[0081] The outer circumferential sides of the upper ends of the peripheral shaft 2-4 and the intermediate shaft 2-8 are respectively covered with a circular baffle 2-9;

[0082] The baffle 2-9 is located directly below the protrusion 2-11;

[0083] The top of the spring 2-7 contacts the bottom surface of the baffle 2-9;

[0084] The top surface of the baffle 2-9 contacts the bottom surface of the spring piece 2-100 of the buckle 2-10.

[0085] It should be noted that the baffle 2-9 is clearance-fitted with the peripheral shaft 2-4 and the intermediate shaft 2-8. The baffle 2-9 is pressed by the spring 2-7 and can move up and down on the circumferential outer side of the peripheral shaft 2-4 and the intermediate shaft 2-8.

[0086] It should be noted that, for the present invention, the lower end of the capacitor monomer 2-1 passes through the hole on the bracket 2-3 (i.e., the capacitor insertion hole 31), and then contacts the pressure plate 2-2. The spring 2-7 vertically passes through the peripheral shaft 2-4 or the intermediate shaft 2-8, and the upper end of the spring 2-7 contacts the baffle 2-9, and the lower end contacts the intermediate shaft guide cylinder 2-61 or the peripheral shaft guide cylinder 2-62.

[0087] In a specific implementation, when three peripheral shaft guide cylinders 2-62 are provided on the top of the guide seat 2-6, the three peripheral shaft guide cylinders 2-62 are respectively inserted with a peripheral shaft 2-4;

[0088] Three buckles 2-10 are provided at the bottom of the pressing plate 2-2 at positions corresponding to the three peripheral shafts 2-4;

[0089] Furthermore, the three buckles 2-10 are arranged in a circle.

[0090] It should be noted that, for the present invention, three buckles arranged in a circle and one buckle located at the center of the pressing plate can be provided at the bottom of the pressing plate 2 - 2 .

[0091] In the present utility model, in a specific implementation, the middle and lower ends of the peripheral shaft 2-4 and the intermediate shaft 2-8 are cylindrical, and the top ends thereof are spherical protrusions.

[0092] Compared with the prior art, the novel supercapacitor module provided by the utility model has the following advantages:

[0093] Beneficial effects:

[0094] 1. Through the utility model, even if multiple capacitor cells are tilted when they are first inserted into the capacitor insertion hole 31, the pressure plate tilts as the capacitor (i.e., the capacitor cell 2-1) tilts, and the spring 2-7 on the peripheral axis 2-4 is compressed to provide elastic force, which can also press the tilted capacitor cell tightly to ensure the anti-seismic performance of the capacitor cell.

[0095] 2. By applying the utility model, when multiple capacitor cells that have been welded to the busbar are placed, even if the bottom heights of the multiple capacitor cells are uneven due to poor consistency in the welding process between the capacitor cells and the busbar, the capacitor cells can be compressed by different amounts of spring compression on the peripheral axis and the intermediate axis under each capacitor cell, thereby ensuring that the multiple capacitor cells can be placed stably and significantly enhancing the anti-seismic performance.

[0096] 3. The utility model has wide applicability and can be applied to capacitors of various types.

[0097] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
