Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a lead-acid battery that is easy to maintain and can be flexibly connected in series. Background Technology

[0002] A storage battery is an electrochemical device that converts electrical energy into chemical energy and then converts chemical energy back into electrical energy when it needs to be discharged. Its working principle is as follows: during charging, external electrical energy is used to regenerate the internal active materials and store electrical energy as chemical energy. When it needs to be discharged, the chemical energy is converted back into electrical energy for output. Common voltage specifications for traditional lead-acid batteries include 2V, 6V, and 12V, among which 2V voltage usually corresponds to a single battery cell.

[0003] However, existing technologies have some problems: In actual use, when a single cell of a 6V or 12V lead-acid battery is damaged, due to the limitations of its overall structure, it is often difficult to replace or repair the damaged cell individually, resulting in the entire battery becoming unusable and having to be scrapped. This not only wastes resources but also significantly increases the cost of use. In addition, existing lead-acid batteries have poor flexibility in assembly and combination, making it difficult to quickly string them into battery systems of different voltages or capacities according to actual needs, and thus failing to adapt well to diverse application scenarios. Therefore, we propose a lead-acid battery that is easy to repair and can be flexibly strung together. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lead-acid battery that is easy to repair and can be flexibly assembled. Through the design of the first docking frame, the second docking frame, and the plug, it solves the problems of difficult repair and inflexible assembly of existing lead-acid batteries when a single cell is damaged.

[0005] The purpose of this utility model is achieved as follows: a lead-acid battery that is easy to maintain and flexibly connected in series includes a battery cell. A first docking frame and a second docking frame are fixedly installed on the surface of the battery cell. An insert block is movably installed inside the first docking frame. A round hole is opened on the top of the second docking frame. Adjacent battery cells can be spliced ​​together through the first docking frame, the second docking frame and the insert block. The insert block is also connected to the first docking frame through a sliding component. The sliding component facilitates the control of the position of the insert block to realize the disassembly and assembly of the battery cells.

[0006] Optionally, the sliding assembly includes a top plate, which is movably mounted on the top of the first docking frame. The top of the first docking frame has a through hole, and a connecting block is fixedly mounted on the bottom of the top plate. The other end of the connecting block passes through the through hole and is fixedly connected to the insert block.

[0007] Optionally, two pins are movably inserted into the top plate, and a pull handle is fixedly connected between the tops of the two pins.

[0008] Optionally, a spring is movably sleeved on the outer surface of the pin, and the two ends of the spring are respectively fixedly connected to the top plate and the pull handle.

[0009] Optionally, the first docking frame is distributed on two adjacent sides of the vertical plane of the battery cell, and the second docking frame is distributed on the other two sides of the vertical plane of the battery cell, with the first docking frame and the second docking frame arranged in a centrally symmetrical manner.

[0010] Optionally, the insert has a square shape, and its size is adapted to the inner cavity size of the second docking frame, the inner wall of the second docking frame being coated with a lubricating layer.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, by setting up a first docking frame, a second docking frame, an insert block, and a sliding component, allows workers to assemble multiple battery cells into battery systems of different voltages or capacities. This enables flexible stringing of battery cells and adapts to diverse application scenarios. When a battery cell in the stringed battery system is damaged, workers can quickly disconnect the damaged cell from adjacent battery cells using the sliding component, thus separating the damaged cell from the whole for individual repair or replacement. Unlike traditional lead-acid batteries, where the entire battery is scrapped due to a single cell failure, this invention significantly reduces resource waste and lowers user costs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown in the figure, the present invention provides a lead-acid battery that is easy to maintain and flexibly connected in series, including a battery cell 1. A first docking frame 2 and a second docking frame 3 are fixedly installed on the surface of the battery cell 1. An insert 4 is movably installed inside the first docking frame 2. A round hole 8 is opened on the top of the second docking frame 3. Adjacent battery cells 1 can be spliced ​​together through the first docking frame 2, the second docking frame 3 and the insert 4. The insert 4 is also connected to the first docking frame 2 through a sliding component. The sliding component facilitates the control of the position of the insert 4 to realize the disassembly and assembly of the battery cell 1.

[0022] Furthermore, the sliding assembly includes a top plate 5, which is movably mounted on the top of the first docking frame 2. The top of the first docking frame 2 has a through hole 6, and a connecting block 7 is fixedly mounted on the bottom of the top plate 5. The other end of the connecting block 7 passes through the through hole 6 and is fixedly connected to the insert block 4.

[0023] By moving the top plate 5, the connecting block 7 can move the insert block 4. When splicing two adjacent battery cells 1, a part of the insert block 4 can be moved into the second docking frame 3, thus achieving the splicing of two adjacent battery cells 1. Similarly, during disassembly, the top plate 5 can be used to move all of the insert block 4 into the first docking frame 2, thereby terminating the connection between the two battery cells 1.

[0024] Furthermore, two pins 9 are movably inserted into the top plate 5, and a pull handle 10 is fixedly connected between the tops of the two pins 9.

[0025] When the staff moves part of the plug 4 into the second docking frame 3, the bottom end of the pin 9 can be inserted into the round hole 8, thereby limiting the top plate 5 and limiting the plug 4 between the first docking frame 2 and the second docking frame 3, so that the two adjacent battery cells 1 can maintain a stable connection.

[0026] Furthermore, a spring 11 is movably sleeved on the outer surface of the pin 9, and the two ends of the spring 11 are fixedly connected to the top plate 5 and the handle 10, respectively.

[0027] By setting the spring 11 to a stretched state, the spring 11 will cause the pin 9 to tend to move downward due to its elasticity. Thus, when the pin 9 is inserted into the round hole 8, the bottom end of the pin 9 can be stably kept in the round hole 8, thereby stably maintaining the limiting effect on the top plate 5 and the insert block 4.

[0028] Furthermore, the first docking frame 2 is distributed on two adjacent sides of the vertical plane of the battery cell 1, and the second docking frame 3 is distributed on the other two sides of the vertical plane of the battery cell 1. The first docking frame 2 and the second docking frame 3 are arranged in a centrally symmetrical manner.

[0029] By setting the positions of the first docking frame 2 and the second docking frame 3, the battery cells 1 can be spliced ​​in different directions according to the requirements, thereby achieving the effect of flexibly stringing the battery cells 1 together.

[0030] Furthermore, the insert 4 has a square shape, and its size is adapted to the inner cavity size of the second docking frame 3. The inner wall of the second docking frame 3 is coated with a lubricating layer.

[0031] By adapting the size of the second docking frame 3 to the plug 4 and by coating the inner wall of the second docking frame 3 with a lubricating layer, it is easier for workers to move or remove the plug 4 from the second docking frame 3, thereby facilitating the assembly, disassembly and maintenance of the battery cell 1.

[0032] Working principle and usage process of this utility model:

[0033] In actual construction, each battery cell 1 is an independent sealed structure, containing the basic components of a lead-acid battery, such as positive and negative plates and electrolyte. It can independently perform energy storage and release functions. The rated voltage of a single battery cell 1 is 2V. When assembling multiple battery cells 1, workers only need to align the first mating frame 2 on one battery cell 1 with the second mating frame 3 on another battery cell 1. Figure 3As shown, the top plate 5 is then moved, causing the connecting block 7 to move the insert block 4, moving a portion of the insert block 4 into the second docking frame 3. At the same time, the pin 9 moves to the top of the round hole 8. Due to the restoring effect of the spring 11, the pin 9 moves downward, inserting its bottom end into the round hole 8, maintaining the limiting effect on the top plate 5 and the insert block 4. This achieves the splicing between two battery cells 1. The operator can repeat this operation multiple times as needed to achieve flexible stringing of battery cells 1, forming battery systems that meet different needs. This fully demonstrates the flexibility and adaptability of this utility model in assembly and combination, better adapting to diverse application scenarios. When one battery cell 1 in the stringed battery system is damaged, the operator can move the top plate 5 and the insert block 4 to disconnect the damaged battery cell 1 from other adjacent battery cells 1, allowing the damaged battery cell 1 to be removed from the battery pack for individual repair or replacement with a new battery cell 1. This eliminates the need to scrap the entire lead-acid battery, greatly reducing usage costs and improving resource utilization.

[0034] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
