[0018] The utility model is described in detail below in combination with the drawings and examples.

[0019] This utility model relates to a detachable nickel sheet for a battery pack, such as... Figure 1 , Figure 2 As shown, the battery pack includes multiple batteries 1 and nickel plates 2. Each battery 1 has a nickel plate cover 3 at its positive terminal. The nickel plate cover 3 has at least four through holes 4 arranged in a circular array. The through holes 4 are used to allow the nickel plates 2 to pass through. In use, the nickel plates 2 first pass through the through holes 4, and then the battery 1 is inserted into the nickel plate cover 3 to hold the nickel plates 2 in place. The nickel plate cover 3 clamps the positive terminal of the battery 1. The nickel plate cover 3 is made of polyimide plastic. Polyimide has excellent insulation and high temperature resistance, which can effectively prevent short circuits between batteries 1 and improve the safety of the battery pack. An insulating protrusion 13 is provided on the side of the nickel plate cover 3 near the through holes 4. When the nickel plates 2 pass through the through holes 4, the nickel plates 2 are in contact with the insulating protrusion 13. The insulating protrusion 13 can prevent the nickel plate cover 3 from being oxidized when current passes through the nickel plates 2.

[0020] like Figures 1-5As shown, two accommodating grooves 5 are formed on the nickel sheet cover 3, the two accommodating grooves 5 are distributed in a circular array on the nickel sheet cover 3, a sliding assembly 6 is arranged in the accommodating groove 5, the sliding assembly 6 is slidably connected with the accommodating groove 5, a through groove 7 is formed in the accommodating groove 5, at least a part of the sliding assembly 6 passes through the through groove 7 and is attached to the battery 1, the sliding assembly 6 clamps the positive electrode of the battery 1 by sliding in the accommodating groove 5, the sliding assembly 6 includes a sliding block 8, a connecting block 9 and a fixed block 10, one end of the connecting block 9 is fixedly connected with the sliding block 8, and the other end is fixedly connected with the fixed block 10, when the user moves the sliding block 8, the connecting block 9 is slidably connected with the through groove 7, the height of the through groove 7 gradually decreases from right to left, and the total reduction height is 0.1-3mm, so that when the user moves the sliding block 8, the top and bottom of the connecting block 9 are gradually subjected to increasing pressure, so that the sliding assembly 6 cannot be easily moved while keeping clamping the positive electrode of the battery 1, and the fixed block 10 is used to clamp the battery 1, the cross section of the fixed block 10 is arc-shaped, the arc-shaped structure enables the fixed block 10 to better fit the positive electrode of the battery 1, the height of the fixed block 10 is not greater than that of the positive electrode of the battery 1, so that the positive electrode of the battery 1 can be effectively clamped, both sides of the accommodating groove 5 are provided with a sliding groove 11, one side of the sliding block 8 close to the connecting block 9 is provided with two protrusions 12, the protrusions 12 are slidably connected with the sliding groove 11, one side of the sliding block 8 close to the accommodating groove 5 is arc-shaped, and the sliding block 8 is slidably connected with the accommodating groove 5 by sliding the protrusions 12 in the sliding groove 11, the depth of the accommodating groove 5 gradually decreases from left to right, and the thickness of the sliding block 8 also gradually decreases from left to right, when the sliding block 8 moves from the side with small depth of the accommodating groove 5 to the side with large depth of the accommodating groove 5, the sliding block 8 drives the fixed block 10 to gradually extend into the inside of the nickel sheet cover 3, so that the positive electrode of the battery 1 is more closely attached, the connectivity of the nickel sheet cover 3 and the positive electrode of the battery 1 is improved, and the thickness of the left side of the sliding block 8 is greater than the depth of the accommodating groove 5, so that the left side of the sliding block 8 always extends out of the accommodating groove 5, facilitating the user to move the sliding block 8.

[0021] Working principle: first, the user arranges the nickel sheets 2 through the through hole 4, then covers the nickel sheet cover 3 on the top of the battery 1, the positive electrode of the battery 1 is pressed against the nickel sheets 2, and then the sliding block 8 is moved along the side with large depth of the accommodating groove 5, in the moving process, the connecting block 9 is clamped by the through groove 7, finally, the fixed block 10 is closely attached to the positive electrode of the battery 1, and the sliding assembly 6 is also not easily moved, when the user needs to disassemble the nickel sheet cover 3, the sliding block 8 is moved in the opposite direction, the fixed block 10 is away from the positive electrode of the battery 1, so that the nickel sheet cover 3 can be easily removed from the battery 1.
