Description

Technical Field

[0001] This utility model belongs to the field of lithium battery technology, and specifically relates to a moisture-proof lithium battery. Background Technology

[0002] Moisture-proof lithium batteries are a type of lithium battery specially designed to prevent moisture from entering and damaging the internal components. Moisture entering the battery can cause problems such as electrolyte decomposition, corrosion of electrode materials, or electrical short circuits, thereby reducing battery performance and lifespan. Existing moisture-proof measures typically include placing moisture-proof components inside the lithium battery casing, such as desiccant packs, which absorb moisture that enters the battery, keeping the internal environment dry.

[0003] Existing moisture-proof lithium batteries use moisture-proof components (such as desiccant packs) inside the lithium battery casing to absorb moisture from the lithium cells inside, keeping the inside dry and thus achieving moisture protection. However, these moisture-proof components gradually lose their moisture-absorbing and drying effect after prolonged use. Furthermore, because they are located inside the lithium battery casing, they usually require special tools to disassemble and replace, increasing maintenance difficulty. Moreover, the disassembly and reassembly process is time-consuming, which is a significant drawback for scenarios requiring rapid resumption of operation. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a moisture-proof lithium battery that allows for quick disassembly and replacement of failed moisture-proof components without relying on specialized tools, greatly simplifying the maintenance process. Furthermore, it allows for the replacement of moisture-proof components in the shortest possible time, thereby improving the maintenance efficiency of lithium batteries.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a moisture-proof lithium battery, including a shell, a square groove plate is provided inside the shell, a lithium battery cell is provided between the square groove plate and the shell, a sliding shell is slidably provided at the lower end of the shell, a plurality of placement frames are provided inside the sliding shell, and a moisture-proof and moisture-absorbing component is placed inside each of the plurality of placement frames, a mounting shell is provided on the right side of the shell, a plurality of sliding columns are slidably provided inside the mounting shell, a docking protrusion is provided between one end of the plurality of sliding columns, the sliding columns and the docking protrusion are fixed by welding, a push plate is provided between the other ends of the plurality of sliding columns, a docking slot is provided at the upper right side of the sliding shell to cooperate with the docking protrusion, an elastic drive component is provided between the docking protrusion and the mounting shell, the elastic drive component can drive the docking protrusion to move, the drive component includes a plurality of springs provided between the docking protrusion and the mounting shell, the plurality of springs are respectively sleeved on the outer arc surface of the corresponding sliding columns, a push plate is provided between the upper ends of the sliding columns, the moisture-proof and moisture-absorbing component is a drying and moisture-absorbing bag, and a frame-shaped sealing gasket is provided on the right side of the shell.

[0006] As a further improvement of this utility model, multiple anti-collision reinforcing ribs are provided on both the front and rear sides of the outer shell, and the multiple anti-collision reinforcing ribs are arranged at equal intervals.

[0007] As a further improvement of this utility model, two mounting plates are provided at the lower end of the outer shell. The two mounting plates are positioned in a corresponding manner, and multiple mounting holes are provided inside the two mounting plates.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] Firstly, during the charging and discharging process of a lithium battery, the internal desiccant can absorb moisture from the lithium battery cells inside the casing, keeping the inside dry and thus achieving moisture protection for the lithium battery. Furthermore, the frame-type sealing gasket can achieve a seal between the casing and the sliding shell, preventing moisture from entering the interior of the casing and further improving the moisture resistance of the lithium battery.

[0010] Secondly, by pulling the pull plate, the docking protrusion on the sliding column can be disengaged from the inside of the docking slot. At this time, the spring is in a compressed state. Then, the sliding shell is pulled out from the inside of the outer shell by the pull plate, and the desiccant pack inside the placement frame is replaced. After replacement, the sliding shell is slid into the inside of the outer shell, and the docking slot is aligned with the upper and lower positions of the docking protrusion. Then, the push plate is released, and the spring quickly rebounds, allowing the docking slot to be inserted into the inside of the docking protrusion. This enables the quick replacement of the desiccant pack, allowing for the rapid disassembly and replacement of failed moisture-proof components without relying on professional tools, greatly simplifying the maintenance process. It also allows the moisture-proof components to be updated in the shortest possible time, improving the maintenance efficiency of lithium batteries.

[0011] Thirdly, the impact-resistant reinforcing ribs on the outer casing can increase the hardness of the casing, prevent the lithium battery from being damaged after being impacted, and improve the durability of the lithium battery. Attached Figure Description

[0018] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0019] like Figure 1 , 2 As shown in Figures 3 and 4, a moisture-proof lithium battery includes a casing 101. A square groove plate 107 is disposed inside the casing 101. A lithium battery cell 108 is disposed between the square groove plate 107 and the interior of the casing 101. A sliding shell 103 is slidably disposed at the lower end of the casing 101. Multiple placement frames 105 are disposed inside the sliding shell 103, and each of the multiple placement frames 105 contains a moisture-proof and moisture-absorbing component. A mounting shell 202 is disposed on the right side of the casing 101. Multiple sliding posts 203 are slidably disposed inside the mounting shell 202. A docking protrusion 205 is provided at one end, and a push plate 201 is provided at the other end of multiple sliding columns 203. A docking groove 206 is provided at the upper right side of the sliding shell 103 to cooperate with the docking protrusion 205. An elastic drive component is provided between the docking protrusion 205 and the mounting shell 202. The elastic drive component can drive the docking protrusion 205 to move. The moisture-proof and moisture-absorbing component is a drying and moisture-absorbing bag 106. A frame-shaped sealing gasket 110 is provided on the right side of the shell 101. The shell 101 and the frame-shaped sealing gasket 110 are bonded together.

[0020] like Figure 2 , 3 As shown, the drive assembly includes multiple springs 204 disposed between the docking boss 205 and the mounting shell 202. The multiple springs 204 are respectively sleeved on the outer arc surface of the corresponding sliding column 203, and a push plate 201 is disposed between the upper ends of the sliding column 203.

[0021] like Figure 1As shown, two mounting plates 102 are provided at the lower end of the outer casing 101. The outer casing 101 and the mounting plates 102 are fixed together by welding. Multiple mounting holes are provided inside the two mounting plates 102. The lithium battery can be quickly fixed in a suitable position through the mounting holes inside the mounting plates 102 and with mounting bolts.

[0022] By connecting the power cord to the positive and negative terminals that are electrically connected to the lithium battery cell 108, the lithium battery can be charged and discharged. During the charging and discharging process of the lithium battery, the internal desiccant pack 106 can absorb moisture from the lithium battery cell 108 inside the outer casing 101, keeping the inside dry and thus achieving moisture protection for the lithium battery.

[0023] When it is necessary to replace the failed moisture-absorbing pack 106, by pulling the pull plate 104, the docking protrusion 205 on the sliding column 203 can be disengaged from the inside of the docking slot 206. At this time, the spring 204 is in a compressed state. Then, the sliding shell 103 is pulled out from the inside of the outer shell 101 by the pull plate 104, and the moisture-absorbing pack 106 inside the placement frame 105 is replaced. After replacement, the sliding shell 103 is slid into the inside of the outer shell 101, so that the docking slot 206 corresponds to the upper and lower positions of the docking protrusion 205. Then, the push plate 201 is released, and the spring 204 quickly rebounds, so that the docking slot 206 is inserted into the inside of the docking protrusion 205, thereby realizing the quick replacement of the moisture-absorbing pack 106.

[0024] The frame-type sealing gasket 110 can achieve a seal between the outer shell 101 and the sliding shell 103, which can prevent moisture from entering the interior of the outer shell 101.

[0025] According to another embodiment of the present invention, such as Figure 1 As shown, multiple anti-collision reinforcing ribs 109 are provided on both the front and rear sides of the outer casing 101.
