Description

Technical Field

[0001] This utility model relates to the field of zinc-nickel battery technology, specifically to a convenient bolt-connected zinc-nickel battery. Background Technology

[0002] Zinc-nickel batteries have become important in fields such as automotive starting power supplies, electric bicycles, backup power supplies and energy storage stations due to their advantages such as low cost and good high-current discharge performance. As a key link in realizing the power transmission of zinc-nickel batteries, the structure design of the electrode connection directly affects the battery's sealing, conductivity and service life.

[0003] Traditional zinc-nickel battery electrode posts are typically welded or cast to the battery top cover. If these posts are damaged, corroded, or experience poor contact, repairs require complete battery disassembly, sometimes necessitating complex procedures like using a hot air gun for electrode replacement. This is not only time-consuming and labor-intensive but also carries the risk of deformation of the battery top cover due to improper handling, potentially leading to electrolyte leakage and increased repair risks. Therefore, there is an urgent need to design a convenient bolt-on connection method for zinc-nickel batteries to address these issues. Utility Model Content

[0007] In a preferred embodiment of this utility model, the electrode assembly includes a bolt inserted into an electrode socket, an electrode connector is provided at one bottom end of the bolt, a sealing rubber ring is sleeved on the outer wall of the bolt, the sealing rubber ring is located inside the electrode socket, and a sealing gasket is sleeved on the bolt.

[0008] The sealing gasket is located on the top outer wall of the top cover. A flat gasket is provided above the sealing gasket, and several nuts are provided on the flat gasket. The nuts are threadedly engaged with the bolts, and the connecting guide plate is located between two nuts.

[0009] In a preferred embodiment of this utility model, the injection assembly consists of an injection hole, a threaded hole, a rubber sleeve, and a bolt plug;

[0010] The injection hole is located on the top plate, the threaded hole is located at the top of the injection hole, the rubber sleeve is fitted onto the top of the injection hole, and the bolt plug is threaded into the threaded hole.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown in the figure, a convenient bolt-connected zinc-nickel battery provided by this utility model embodiment includes a housing 1. The housing 1 is characterized by having a top cover 2 on its top, and a plurality of electrode insertion holes 21 on the top cover 2. Electrode assemblies 4 are inserted into the electrode insertion holes 21. Connecting guide plates 5 are provided on the electrode assemblies 4, and the connecting guide plates 5 connect electrode assemblies 4 with the same electrode in parallel. A plurality of liquid injection assemblies 3 are provided on the top cover 2.

[0025] In this embodiment, a top cover 2 is provided on the top of the housing 1. The top cover 2 is integrally injection molded from high-strength engineering plastic. Six electrode insertion holes 21 are provided on the top cover 2. Reinforcing ribs 22 are provided at the bottom of the top cover 2. The reinforcing ribs 22 are arranged in a grid pattern to effectively resist the pressure changes generated by the charging and discharging of the battery and prevent the top cover 2 from deforming and causing sealing failure. The outer wall of the housing 1 is provided with protruding strips 11. The protruding strips 11 are vertically and equidistantly distributed on the outer wall of the housing 1. This not only enhances the impact resistance of the housing 1, but also increases the contact area between the housing 1 and the outside world, and improves the heat dissipation effect to a certain extent.

[0026] In this embodiment, an electrode assembly 4 is inserted into the electrode socket 21. A connecting guide 5 is provided on the electrode assembly 4. The connecting guide 5 is made of flexible copper busbar with holes inside, and is directly sleeved on the bolt 41. The connecting guide 5 connects the electrode assemblies 4 with the same electrode in parallel. This design not only realizes the rapid series connection of the battery pack, but also allows the electrode assembly 4 to be finely adjusted within a certain range to adapt to the installation requirements under different working conditions. The electrode assembly 4 includes a bolt 41 inserted into the electrode socket 21. The bolt 41 is made of high-purity copper alloy and the surface is silver-plated, which significantly reduces the contact resistance and improves the conductivity. An electrode connector 42 is provided at one end of the bottom of the bolt 41. The electrode connector 42 is tightly connected to the internal plate of the battery through the bolt 41 to ensure efficient current transmission.

[0027] Specifically, a sealing rubber ring 43 is fitted onto the outer wall of the bolt 41. The sealing rubber ring 43 is located inside the electrode socket 21. The sealing rubber ring 43 is made of fluororubber and has excellent acid and alkali resistance and high temperature resistance. It is in an interference fit state inside the electrode socket 21. When the bolt 41 is screwed in, the rubber ring is squeezed and deformed, forming the first sealing barrier between the electrode and the top cover 2. A sealing gasket 46 is fitted onto the bolt 41. The sealing gasket 46 is made of oil-resistant nitrile rubber. Together with the flat gasket 45 and the nut 44, it forms the second protective structure.

[0028] Specifically, the sealing gasket 46 is located on the top outer wall of the top cover 2. A flat gasket 45 is provided above the sealing gasket 46 to increase the contact area with the sealing gasket 46. Two nuts 44 are provided on the flat gasket 45. The nuts 44 are threadedly engaged with the bolts 41. The connecting guide plate 5 is located between the two nuts 44 and is fixed by the two bolts 44.

[0029] In this embodiment, the top cover 2 is provided with a plurality of liquid injection components 3, which are composed of a liquid injection hole 31, a threaded hole 32, a rubber sleeve 33 and a bolt plug 34;

[0030] Specifically, the injection hole 31 is opened on the top plate 2, the threaded hole 32 is opened on the top of the injection hole 31, the rubber sleeve 33 is sleeved on the top of the injection hole 31, the rubber sleeve 33 is sleeved on the top of the injection hole 31, and its inner wall is designed with an annular protrusion to form a tight fit with the injection hole 31 to prevent electrolyte leakage. The bolt plug 34 is threaded in the threaded hole 32. The threaded hole 32 at the top and the bolt plug 34 form a threaded sealing structure. The thread profile adopts a fine tooth design to effectively improve the sealing effect.

[0031] In this embodiment, the liquid injection component 3 is located between the electrode components 4 of two different electrodes, and the bolt plug 34 has a slot for easy disassembly and installation using a common screwdriver.

[0032] Working steps: 1. During assembly, first put the sealing rubber ring 43 on the bolt 41, then pass the bolt 41 through the electrode insertion hole 21 from the bottom of the top cover 2, then put the sealing gasket 46 and flat gasket 45 in sequence, and then tighten them with the nut 44. Next, connect the connecting guide plate 5 to connect the same electrodes, and then fix it with the nut 44.

[0033] 2. Next, seal the top cover 2 with the shell 1, then inject electrolyte into the injection hole 31, then put in the rubber sleeve 33, and then screw the bolt plug 34 into the threaded hole 32 with a screwdriver to seal the injection hole 31.

[0034] 3. During disassembly and maintenance, separate the top cover 2 from the housing 1, then remove the screws 44 and other components, then pull out the bolts 41, replace the bolts 41 as needed, and then complete the installation in the same way as above.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
