[0027] See also Figure 1-3 The utility model provides a technical solution: a zinc-nickel battery using tin-plated steel strip as a negative electrode substrate, comprising a battery installation box 1, a hinged seat 2, a box door 3, a partition 4 and a zinc-nickel battery body 500, wherein the partition 4 is fixedly connected in the battery installation box 1 and arranged equidistantly, and the partition 4 is used to separate the zinc-nickel battery body 500, and heat dissipation holes that are evenly distributed and used for heat dissipation of the zinc-nickel battery body 500 are opened on both sides of the battery installation box 1, and the hinged seat 2 is fixedly installed on the inner side wall of the battery installation box 1 and distributed in a mirror-symmetrical manner, and one side of the box door 3 is hinged to the hinged seat 2 through a pin shaft;

[0029] Through the mutual cooperation among the hinged seat 2, the box door 3, the partition 4, the zinc-nickel battery body 500 and the adjustable limiting mechanism 600 on the battery installation box 1, the zinc-nickel battery body 500 can be conveniently disassembled and maintained, so that the staff can take and place the zinc-nickel battery body 500. At the same time, the gap between the zinc-nickel battery bodies 500 can be expanded to achieve separated installation, which is conducive to the dissipation of heat and improves the heat dissipation efficiency and effect, thereby effectively improving the use effect of the existing zinc-nickel battery during disassembly and assembly.

[0030] In this embodiment, the zinc-nickel battery body 500 is a structure used to improve the performance of the zinc-nickel battery.

[0031] like Figure 1 and Figure 3 As shown, the zinc-nickel battery body 500 includes an aluminum-plastic packaging film 501, an insulating sheet 502, a positive electrode ear 503, a negative electrode ear 504, a positive electrode substrate 505, a separator 506 and a negative electrode substrate 507; the separator 506 is located between the opposite sides of the positive electrode substrate 505 and the negative electrode substrate 507, and the positive electrode ear 503 and one end of the negative electrode ear 504 are coated between the positive electrode substrate 505, the separator 506 and the negative electrode substrate 507, and the other ends of the positive electrode ear 503 and the negative electrode ear 504 are fixedly connected with the insulating sheet 502 respectively, and the aluminum-plastic packaging film 501 is coated between the insulating sheet 502, the positive electrode ear 503, the negative electrode ear 504, the positive electrode substrate 505, the separator 506 and the outer side of the negative electrode substrate 507.

[0032] It should be noted that the negative electrode substrate 507 is composed of tin-plated steel strip in order to improve the performance of the zinc-nickel battery body 500 .

[0033] In this embodiment, the adjustable limiting mechanism 600 is a structure for conveniently disassembling and maintaining the zinc-nickel battery body 500 .

[0034] like Figure 1 and Figure 2 As shown, the adjustable limiting mechanism 600 includes a fixed block 601 fixedly installed between the inner walls of the battery installation box 1; two mirror-symmetrical installation grooves 602 are opened inside the fixed block 601; two mirror-symmetrical groups of adjusting fastening components are installed in the installation grooves 602, and the limiting moving components and the auxiliary moving components installed in the limiting moving components are respectively installed on both sides of the adjusting fastening components; the adjusting fastening components are connected to the auxiliary moving components through the limiting moving components, and the adjusting fastening components drive the limiting moving components to move outside the auxiliary moving components.

[0035] It should be noted that the adjustment and fastening assembly includes a card block 6031, a movable plate 6032 and a toggle plate 6033; one end of the card block 6031 passes through the mounting groove 602 and extends into the box door 3 to be connected to the box door 3, and the other end is located in the mounting groove 602, one side of the movable plate 6032 is fixedly connected to one side of the card block 6031, and the other side is fixedly connected to one side of the toggle plate 6033; a movable hole 604 is provided on the inner side wall of the mounting groove 602 for the movable plate 6032 to slide against; the toggle plate 6033 pushes the movable plate 6032 to move, thereby driving the card block 6031 to move.

[0036] It is understandable that a slot 608 for the clamping block 6031 to engage with is provided on a side of the door 3 away from the hinge seat 2 in order to limit the movement of the door 3 .

[0037] In addition, the limiting movement assembly includes a slider 6051 and an adjustment block 6052; one side of the two sliders 6051 is fixedly installed on both sides of the clamping block 6031 by bolts, and one side of the adjustment block 6052 is fixedly connected to one side of the slider 6051 in order to stably drive the clamping block 6031 to move.

[0038] In this embodiment, a limiting groove 606 for the adjusting block 6052 to slide against is provided on the inner wall of the installation groove 602, so as to make the adjusting block 6052 move more stably and also to limit the moving distance of the slider 6051.

[0039] It should also be noted that the auxiliary moving assembly includes a fixed support plate 6071, a sliding rod 6072 and a return spring 6073; one side of the fixed support plate 6071 is fixedly mounted on the inner side wall of the mounting groove 602, and the number of fixed support plates 6071 is two and they are distributed in a mirror-symmetrical manner, the two ends of the sliding rod 6072 are respectively fixedly connected to the opposite sides of the two fixed support plates 6071, and the return spring 6073 is sleeved on the outer side of the sliding rod 6072;

[0040] The return spring 6073 is located between the opposite sides of the two sliders 6051. The movement of the block 6031 drives the slider 6051 to move. The return spring 6073 elastically contracts under the thrust generated by the movement of the slider 6051. This is to enable the moving block 6031 to be pushed back to its original position under the elastic return action of the return spring 6073.

[0041] The working principle of the above embodiment is:

[0042] When a zinc-nickel battery body 500 in the battery installation box 1 has a problem and needs to be taken out for maintenance, first pinch the toggle plate 6033 with two fingers and move in the opposite direction. At this time, the movable plate 6032 moves under the thrust of the toggle plate 6033 and drives the clamping block 6031 to move. Since the slider 6051 can only move in the installation groove 602 under the sliding connection cooperation between the adjustment block 6052 and the limit groove 606, the slider 6051 moves on the outside of the sliding rod 6072 under the thrust generated when the clamping block 6031 moves, and the reset spring 6073 is elastically contracted. When the clamping block 6031 is separated from the clamping groove 608, the box door 3 can be opened by the hinged action with the hinge seat 2, so that the faulty zinc-nickel battery body 500 can be taken out.

[0043] Compared with the prior art: the zinc-nickel battery using tin-plated steel strip as the negative electrode substrate can facilitate the disassembly and maintenance of the zinc-nickel battery body 500 through the mutual cooperation of the hinged seat 2, the box door 3, the partition 4, the zinc-nickel battery body 500 and the adjustable limiting mechanism 600 on the battery installation box 1, so that the staff can take and place the zinc-nickel battery body 500. At the same time, the gap between the zinc-nickel battery bodies 500 can be expanded to achieve separated installation, which is conducive to the dissipation of heat and improves the heat dissipation efficiency and effect, thereby effectively improving the use effect of the existing zinc-nickel battery during disassembly and assembly, and solving the problem of poor use effect of the existing zinc-nickel battery during disassembly and assembly.
