Technical Field
[0001] This utility model belongs to the field of new energy battery technology, and more specifically, it relates to a self-melting nickel sheet for a new energy battery pack. Background Technology
[0002] New energy batteries generally refer to batteries used for storing and supplying energy. They are mainly used in new energy fields such as solar energy, wind energy, and electric vehicles. With the widespread application of new energy batteries in electric vehicles, energy storage systems, and various electronic products, the safety of battery packs has become increasingly important.
[0003] Based on the above, the inventors have discovered the following problems: In the process of using existing new energy battery nickel sheets, most nickel sheets have a slow melting reaction, which increases the risk of use. At the same time, technicians usually use their hands to stabilize the nickel sheets during the welding process, which can easily damage their hands. Moreover, stabilizing the nickel sheets by hand is unstable and can easily cause displacement, which reduces welding efficiency.
[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a self-melting nickel sheet for new energy battery packs, in order to achieve a more practical value. Utility Model Content

Both the upper and lower nickel sheets are equipped with clips. The clips are embedded and connected to the slots. The upper nickel sheet is welded to the top of the battery box, and the lower nickel sheet is welded to the bottom of the battery box. Both the upper and lower nickel sheets are provided with conductive components on their surfaces.
[0007] Furthermore, the card strip and the card slot are bonded together by a temperature-sensitive hydrogel.
[0008] Furthermore, the conductive component includes an insulating groove on the surface of the upper and lower nickel plates, a broken arm is installed in the insulating groove, a contact part is provided at the center of the broken arm, a plurality of battery cells are installed in the battery box, and the upper and lower nickel plates are welded to the two-stage of the battery cells through the contact part.
[0009] Furthermore, the surface of the contact portion is provided with a pair of auxiliary grooves.
[0010] Furthermore, the surface of the contact portion is provided with a flow-diverting groove.
[0011] Furthermore, the shape of the diversion channel is as follows: shape.
[0012] Furthermore, both the upper and lower nickel sheets have several through grooves on their surfaces.
[0013] Furthermore, the thickness of the upper and lower nickel sheets is 0.5 mm, and the material of the upper and lower nickel sheets is a nickel alloy.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] By using a clip and slot for embedding connection, when welding the upper and lower nickel sheets, the upper and lower nickel sheets are embedded in the slot of the battery box through the clip. The embedded connection of the clip and slot stabilizes the upper or lower nickel sheet, improving welding stability and efficiency.
[0016] By using temperature-sensitive hydrogel, the hydrogel contracts and releases its pre-stored elastic potential energy at high temperatures, preventing the upper or lower nickel sheet from breaking during expansion.
[0017] By using the broken arm, the upper and lower nickel sheets melt at high temperatures, protecting the battery box. During welding, the spot welding head is located in the auxiliary groove on the contact part, which can prevent the spot welding head from sliding on the surface of the upper nickel sheet and improve welding efficiency.

[0029] This utility model provides a self-fusing nickel sheet for a new energy battery pack, including an upper nickel sheet 1, a lower nickel sheet 2, and a battery box 3. Both ends of the battery box 3 are provided with slots 5. Each of the upper nickel sheet 1 and the lower nickel sheet 2 is equipped with a retaining strip 12, which is embedded into the slot 5. The upper nickel sheet 1 is welded to the top of the battery box 3, and the lower nickel sheet 2 is welded to the bottom of the battery box 3. The surfaces of both the upper and lower nickel sheets 1 and 2 are provided with conductive components, which are embedded into the slots 5 via the retaining strips 12. When welding the upper nickel sheet 1 and the lower nickel sheet 2, the upper nickel sheet 1 and the lower nickel sheet 2 are embedded into the slots 5 of the battery box 3 via the retaining strips 12. The embedded connection between the retaining strips 12 and the slots 5 stabilizes the upper nickel sheet 1 or the lower nickel sheet 2, improving welding stability and efficiency.
[0030] The card strip 12 and the card slot 5 are bonded together by a temperature-sensitive hydrogel. When the temperature-sensitive hydrogel is used, it contracts and releases the pre-stored elastic potential energy at high temperatures, thus preventing the upper nickel sheet 1 or the lower nickel sheet 2 from breaking during expansion.
[0031] The conductive component includes an insulating groove 6 on the surface of the upper nickel sheet 1 and the lower nickel sheet 2. A broken arm 7 is installed in the insulating groove 6.

The upper nickel sheet 1 and the lower nickel sheet 2 are welded to the battery cells 4 in two stages through the contact part 8. By using the broken arm 7, the upper nickel sheet 1 and the lower nickel sheet 2 melt at high temperature, thus protecting the battery box 3.
[0032] The surface of the contact part 8 is provided with a pair of auxiliary grooves 10. By using the auxiliary grooves 10, the spot welding head is located in the auxiliary grooves 10 during welding, which can prevent the spot welding head from sliding on the surface of the upper nickel sheet 1 and improve welding efficiency.
[0033] The surface of the contact portion 8 is provided with a flow divider groove 11.
[0034] The shape of the diversion channel 11 is as follows: The shape of the flow divider 11 is as follows: The shape allows for the release of thermal stress on the surrounding area.
[0035] The surfaces of the upper nickel sheet 1 and the lower nickel sheet 2 are each provided with several through grooves 9.
[0036] The upper nickel sheet 1 and the lower nickel sheet 2 are 0.5 mm thick and are made of nickel alloy.
[0037] The specific usage and function of this embodiment are as follows:
[0038] First, check the integrity of the device. Only after confirming it is correct can it be used. During use, first inject thermosensitive hydrogel into the slot 5. Then, embed the upper nickel sheet 1 and lower nickel sheet 2 into the slot 5 of the battery box 3 using the retaining strip 12. The retaining strip 12 and slot 5 stabilize the upper nickel sheet 1 or lower nickel sheet 2, improving welding stability. The spot welding head is located in the auxiliary groove 10 on the contact part 8. The upper nickel sheet 1 and lower nickel sheet 2 are then welded to the two stages of the battery cell 4. The shape of the shunt groove 11 is... The device can release thermal stress on the surrounding area. At high temperatures, the thermosensitive hydrogel contracts and releases the pre-stored elastic potential energy, preventing the upper nickel sheet 1 or the lower nickel sheet 2 from breaking during expansion. With the use of the broken arm 7, the upper nickel sheet 1 and the lower nickel sheet 2 melt at high temperatures, protecting the battery box 3. This device has a novel overall design and simple structure, and is therefore worthy of widespread promotion and use.
