Problems solved by technology

However, none of the above patents can be spliced, and the angle between the welded nickel sheets of the two single batteries cannot be adjusted. The requirements for placing a single battery in the battery pack are relatively high, and welding errors are very likely to occur, and the scope of application is narrow.

Embodiment 1

[0038] refer to Figure 1 to Figure 2 , a splicing spot welding battery nickel sheet, comprising a nickel sheet part 1, the nickel sheet part 1 includes a nickel sheet assembly 11 and a V connector 12, several nickel sheet assemblies 11 are arranged in a rectangle, wherein two nickel sheets arranged vertically The components 11 are staggeredly connected to each other, and the two nickel sheet components 11 arranged horizontally are connected to each other through the V connector 12; the two ends of the V connector 12 are respectively welded with a nickel chip component 11, and the middle part of the V connector 12 It is bent downwards, and the bent part extends downwards into the gap between the two nickel sheet components 11 .

[0039] refer to Figure 3 to Figure 4, the nickel sheet assembly 11 is composed of an annular portion 111 and a handle portion 112, wherein the annular portion 111 and the handle portion 112 are integrally formed, the handle portion 112 passes throug...

Embodiment 2

[0042] The difference between this embodiment and the first embodiment is that the locking structure one 113 in this embodiment is different from the locking structure one 113 in the first embodiment;

[0043] refer to Figure 5 to Figure 6 , the first locking structure 113 is a dot-shaped structure that protrudes upwards, the second locking structure 114 is located above the dot-like structure, and the two coincide with each other, the third locking structure 115 is located below the dot-like structure, and both Snap-in connection, the top of the dot structure is provided with a welding hole 116, this design can also make the two nickel plate assemblies 11 rotate with each other.

Embodiment 3

[0045] The difference between the present embodiment and the first embodiment is only that the parallel nickel sheets 2 are added in the present embodiment;

[0046] refer to Figure 7 , the left side of the nickel sheet part 1 is provided with a parallel nickel sheet 2, and the parallel nickel sheet 2 includes a nickel sheet straight bar 21 and a cross block 22, and the nickel sheet straight bar 21 is provided with some equidistantly distributed cross blocks 22, and the cross block 22 Connected with a cross interface 118, the design of the parallel nickel sheet 2 is to reduce the number of battery connection ports, connect the batteries in series and then in parallel, and effectively use the battery as an energy storage unit.

Abstract

The invention discloses a spliced spot welding type battery nickel sheet and a spot welding process thereof, belongs to the technical field of battery nickel sheets, and solves problems that the requirement for limiting the placement position of a single battery in a battery pack is high, welding position errors easily exist, and the application range is narrow during nickel sheet welding. The nickel sheet comprises a nickel sheet part, wherein the nickel sheet part comprises a plurality of nickel sheet assemblies and V-shaped connecting pieces, a plurality of nickel sheet assemblies are arranged in a rectangular shape, the two longitudinally arranged nickel sheet assemblies are connected with each other in a staggered manner, and the two transversely arranged nickel sheet assemblies are connected with each other through the V-shaped connecting pieces. By utilizing the characteristic of high toughness of the battery nickel sheets, the two nickel sheet assemblies are spliced and fixed in a mutually staggered and superposed manner, and the two spliced nickel sheet assemblies can relatively rotate and adjust the angle so as to adapt to batteries in different placement forms, and a corresponding number of nickel sheet assemblies can be spliced according to different numbers of batteries, so the battery nickel sheet assembly is wide in application range.

Description

technical field [0001] The invention relates to the technical field of battery nickel sheets, in particular to a spliced ​​spot welding type battery nickel sheet and a spot welding process thereof. Background technique [0002] Battery (Battery) refers to a cup, tank or other container or part of a composite container that contains an electrolyte solution and a metal electrode to generate current, and is a device that converts chemical energy into electrical energy. It has positive pole and negative pole. As technology advances, batteries generally refer to small devices that can generate electricity. Such as solar cells. The performance parameters of the battery mainly include electromotive force, capacity, specific energy and resistance. Using the battery as the energy source can obtain a current with stable voltage, stable current, stable power supply for a long time, and little influence from the outside world. A number of batteries are connected to each other to for...
