Description

Technical Field

[0001] The utility model belongs to the technical field of battery grid structures, and particularly relates to a grid structure of a lead-acid battery. Background Art

[0002] At present, the grid structures such as Figure 1 shown are generally adopted for lead-acid batteries. Such grids are not only prone to bending deformation in structure, but also have a poor discharge rate in performance, resulting in a slow battery startup speed. Summary of the Utility Model

[0003] To solve the deficiencies of the prior art, the utility model provides a grid structure of a lead-acid battery, which has high structural strength and can effectively improve the discharge rate.

[0004] To achieve the purpose of the utility model, the following scheme is proposed:

[0005] A grid structure of a lead-acid battery includes: a frame, one side of which extends outward to be provided with an ear, and the inside of the frame corresponding to the side where the ear is located has a current collector plate protruding inwards;

[0006] A plurality of vertical ribs are arranged inside the frame, one end of which is connected to the current collector plate, and the other end extends radially and is connected to the frame outside the current collector plate;

[0007] A plurality of horizontal ribs are arranged inside the frame, each horizontal rib intersects with a plurality of vertical ribs, and both ends of the horizontal rib are respectively connected to opposite sides of the frame, and the horizontal ribs are all arc-shaped structures.

[0008] The beneficial effects of the utility model are as follows: through the combined action of the horizontal ribs designed with an arc structure and the vertical ribs arranged in a radial structure, the overall structural strength of the grid can be improved; by arranging the current collector plate, the current collection area at the ear is increased, thereby improving the current collection efficiency, enabling the current to pass quickly, and when the battery needs to discharge, the discharge rate of the battery can be greatly improved, and the battery startup speed can be increased.

[0013] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will describe the implementation manners of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described in the present utility model are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0014] As Figure 2 shown, a lead-acid battery grid structure includes: a frame 1, on one side of which an ear 2 extends outward, and inside the frame 1 on the side where the ear 2 is located, there is a current collector plate 3 protruding inward.

[0015] Inside the frame 1, there are multiple vertical ribs 4. One end of each vertical rib 4 is connected to the current collector plate 3, and the other end extends radially and is connected to the frame 1 outside the current collector plate 3. The vertical ribs 4 are arranged in a radial structure, which can not only improve the anti-twisting strength of the grid in the direction of the vertical ribs 4, but also reduce the current flow path. The vertical ribs 4 are all connected to the current collector plate 3. If the ear 2 is used as a reference point, then during discharge, the current is denser closer to the ear 2. By setting the current collector plate 3, the current collection area at the ear 2 is increased, thereby improving the current collection efficiency, enabling the current to pass quickly. When the battery needs to discharge, it can greatly improve the discharge rate of the battery and the battery startup speed.

[0016] Inside the frame 1, there are multiple horizontal ribs 5. Each horizontal rib 5 intersects with multiple vertical ribs 4. Both ends of the horizontal rib 5 are respectively connected to opposite sides of the frame 1. The horizontal ribs 5 are all in an arc structure. By acting together with the vertically arranged ribs 4 in a radial structure, the overall structural strength of the grid is further improved. The grid is formed by stamping a single piece of plate.

[0017] Preferably, as Figure 2 shown, outside the frame 1 on the side corresponding to the ear 2, there is a triangular plate 6 protruding outward. The ear 2 is located at the protruding end of the triangular plate 6, further increasing the current collection area at the ear 2, improving the current collection efficiency, and at the same time increasing the connection structural strength between the ear 2 and the frame 1.

[0018] Preferably, as Figure 2 shown, the width of the end of the vertical rib 4 connected to the current collector plate 3 is greater than the width of the other end, so as to increase the current collection area of each vertical rib 4 at the end connected to the current collector plate 3 and accelerate the current passing speed.

[0019] The above are only the preferred embodiments of the present utility model, and do not represent that it is the only one or a limitation to the present utility model. Those skilled in the art should understand that without departing from the scope of the present utility model, various changes or equivalent replacements made to the present utility model all fall within the scope of protection of the present utility model.
