Technical Field

[0001] The utility model relates to the field of batteries, in particular to a lead-acid power battery grid structure which is easy to assemble. Background Art

[0002] Lead-acid power battery grid is a key component used in lead-acid power batteries. It is responsible for the conduction of current and the support of the battery. It is mainly made of lead and its alloys, with excellent conductivity and corrosion resistance, ensuring the stability and reliability of the battery during long-term use. In addition, the design and manufacturing process of the grid also directly affect the performance and safety of the battery.

[0003] The existing lead-acid power battery grid has limited efficiency in current collection, and its reaction efficiency needs to be improved. These problems affect the overall performance and output efficiency of the battery, thereby limiting the competitiveness of lead-acid power batteries in certain application fields to a certain extent. The current collection efficiency of the lead-acid power battery grid is limited by the grid design, and the existing grid is not convenient for uneven pole ears and is not easy to assemble during the battery production process. Utility Model Content

[0004] The main purpose of the utility model is to provide a lead-acid power battery grid structure that is easy to assemble and can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A lead-acid power battery grid structure that is easy to assemble comprises a frame, a connecting mechanism is provided on the top of the frame, the connecting mechanism comprises a connecting block, a pole ear is fixedly connected to the bottom of the connecting block, a main grid is fixedly connected to the bottom of the pole ear, one side of the main grid is fixedly connected to one side of the frame near the top and the bottom, three auxiliary grids are symmetrically provided at the central position of one side of the main grid and near the upper part and the lower part, one end of the three auxiliary grids is fixedly connected to the inner side of the frame near the other side, and the frame, the main grid and the front and rear of the auxiliary grid are all fixedly connected to a plurality of cross bars.

[0007] As a further solution of the utility model, the auxiliary grid and the frame are connected by a fine grid, and the three auxiliary grids are also connected by a fine grid, and a plurality of protrusions are provided on both sides of the fine grid.

[0008] As a further solution of the present invention, the fine grid has a rod-shaped shape, and the protrusion has a semicircular shape.

[0009] As a further solution of the utility model, the three auxiliary grids have the same appearance, and the thickness of the auxiliary grid is equal to that of the fine grid.

[0010] As a further solution of the utility model, the connecting block has a truncated cone shape, and a groove is formed on the top of the connecting block.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-3As shown, a lead-acid power battery grid structure that is easy to assemble includes a frame 1, a connecting mechanism 2 is provided on the top of the frame 1, the connecting mechanism 2 includes a connecting block 3, a pole ear 4 is fixedly connected to the bottom of the connecting block 3, a main grid 5 is fixedly connected to the bottom of the pole ear 4, one side of the main grid 5 is fixedly connected to one side of the frame 1 near the top and bottom, three auxiliary grids 6 are symmetrically provided at the central position of one side of the main grid 5 and near the upper and lower parts, one end of the three auxiliary grids 6 is fixedly connected to the inner side of the frame 1 near the other side, and the front and rear of the frame 1, the main grid 5 and the auxiliary grid 6 are fixedly connected to a plurality of cross bars 8.

[0020] In this embodiment, the auxiliary grid 6 and the frame 1 are connected via a thin grid 7 , and the three auxiliary grids 6 are also connected via the thin grid 7 . A plurality of protrusions 9 are provided on both sides of the thin grid 7 .

[0021] The current can be collected to the auxiliary grid 6 through the fine grid 7, and the gaps between the grids are filled with dilute sulfuric acid.

[0022] In this embodiment, the fine grid 7 has a rod-like shape, and the protrusion 9 has a semicircular shape.

[0023] The bumps 9 can increase the contact area between the grid and the dilute sulfuric acid, increase more electrode reaction areas, and thus improve the reaction efficiency.

[0024] In this embodiment, the three auxiliary grids 6 have the same appearance, and the thickness of the auxiliary grid 6 and the fine grid 7 are equal.

[0025] The three auxiliary grids 6 can concentrate the current into the main grid 5, thereby improving the current gathering capability.

[0026] In this embodiment, the connecting block 3 has a truncated cone shape, and a groove is formed on the top of the connecting block 3 .

[0027] The front of the connecting block 3 can be prevented from entering the rear of another connecting block 3, while the rear of the connecting block 3 can be aligned with the other connecting block 3, thereby facilitating the alignment of different grids.

[0028] In this embodiment, the width of the main gate 5 is greater than that of the auxiliary gate 6, and the width of the auxiliary gate 6 is greater than that of the fine gate 7. By step-by-step convergence, more current can be concentrated on the main gate 5, and the cross-sectional area of ​​the main gate 5 is relatively large, which can reduce resistance.

[0029] It should be noted that the utility model is a lead-acid power battery grid structure that is easy to assemble. When in use, it is easy to align different grids, so as to facilitate subsequent assembly, and at the same time, it can improve the efficiency of current collection, adapt to higher power batteries, and at the same time increase the contact area between the grid and the electrolyte;

[0030] The specific implementation method is to place the connection block 3 of the grid vertically upward, take another grid and place it in the same posture, then place the front part of the connection block 3 of the other grid on the rear part of the groove of the connection block 3 of the previous grid, and connect the two grids. In the same way, any number of grids can be connected, so that the pole ears 4 between the grids are in a straight line, which is convenient for later welding and assembly;

[0031] By providing the fine grid 7 and the cross bar 8, the contact area between the grid and the electrolyte can be increased. A larger contact area can provide more electrode reaction areas, thereby improving the charge and discharge efficiency of the battery, allowing the battery to process current more quickly and provide a more stable output. Because more electrode materials can participate in the reaction and the increase in the contact area can increase the theoretical capacity of the battery, the cross bar 8 is provided so that the grid machine interval will not be isolated by the subsequent wrapping process, so that the electrolyte between different intervals can flow, avoiding the problem of some areas not being in contact with the electrolyte;

[0032] By providing a fine grid 7, an auxiliary grid 6 and a main grid 5, the efficiency of current collection can be improved, so that the plate grid can adapt to higher power batteries, and the gradually increasing grid line cross-section can reduce the internal resistance of the battery, which helps to reduce the energy loss of the battery during the charging and discharging process and improve the energy conversion efficiency of the battery.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
