Description

Technical Field

[0001] This utility model belongs to the field of battery-related technical technology, specifically relating to a high-power valve-regulated battery grid structure. Background Technology

[0002] Currently, high-power batteries are widely used in various industries such as banking, telecommunications, and energy storage. Most companies now adopt a design method with alternating horizontal and vertical ribs. Since the mass of the grid is fixed in the initial design stage, the horizontal ribs of the grid are mainly used to support the entire grid structure, while the vertical ribs play a role in current conduction. Therefore, generally, most of the mass needs to be placed on the vertical ribs, resulting in the horizontal ribs being designed too thin, which affects the overall stability of the structure.

[0003] A search revealed that CN112768703B discloses a long-life, high-power, small valve-regulated lead-acid battery grid, comprising: tabs, a frame, vertical ribs, and horizontal ribs; the frame includes an upper frame, side frames, and a lower frame, with the upper and lower frames arranged opposite each other in the vertical direction, and the two side frames connected to the two ends of the upper and lower frames respectively in the horizontal direction; the upper end of the vertical rib is connected to the upper frame, and the lower end of the vertical rib is connected to the lower frame, with multiple vertical ribs arranged alternately between the two side frames in the horizontal direction; the two ends of the horizontal rib are connected to the two side frames respectively, with multiple horizontal ribs arranged alternately between the upper and lower frames in the vertical direction, and each horizontal rib connected to each vertical rib in the horizontal direction; the number of horizontal ribs is greater than the number of vertical ribs; the tabs are located on the upper frame.

[0004] The existing battery grid technology has the following problems: The existing battery grid uses a crisscross design for the horizontal and vertical ribs, and the width and thickness of the horizontal and vertical ribs are the same. However, during use, the current near the tabs is relatively large. In order to meet the output power requirements, the horizontal and vertical ribs need to maintain a large width and thickness, which will increase the overall weight of the grid. Utility Model Content

[0005] The purpose of this utility model is to provide a high-power valve-controlled battery grid structure to solve the problem mentioned in the background art of increasing the overall mass of the grid by maintaining a large width and thickness of the horizontal and vertical ribs in order to meet the output power requirements.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a grid structure for a high-power valve-regulated storage battery, comprising a frame and a plurality of vertical and horizontal ribs intersecting within the frame. The upper part of the frame is provided with a tab. The width and thickness of the frame near the tab gradually decrease from the other side to form a gradient grid outer edge. The side of the frame with a larger width and thickness of the gradient grid outer edge is the casting port for the horizontal rib. The width and thickness of the vertical ribs gradually decrease from one end near the electrode tab to the other end, and the three vertical ribs near the electrode tab are thickened vertical ribs with a width and thickness greater than the width and thickness of the other vertical ribs. The width and thickness of the horizontal reinforcement gradually decrease from one end near the pouring opening to the other.

[0007] Preferably, auxiliary vertical ribs are provided in the holes located at the edge of the frame.

[0008] Preferably, the transverse reinforcement includes a middle transverse reinforcement and upper and lower transverse reinforcements alternately arranged on both sides of the middle transverse reinforcement, wherein the upper and lower transverse reinforcements are distributed vertically.

[0009] Preferably, the intermediate transverse rib is a thickened rib.

[0010] Compared with the prior art, this utility model provides a high-power valve-regulated battery grid structure, which has the following advantages: This invention can maximize the width of the vertical ribs without reducing the overall strength of the main plate grid and within a limited mass. Combined with the structural design of the horizontal ribs, it can greatly increase the service life of the main plate grid. Attached Figure Description

[0012] 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.

[0013] Please see Figure 1 and Figure 2This utility model provides a technical solution: a grid structure for a high-power valve-controlled storage battery, including a frame 1 and a plurality of vertical ribs 2 and horizontal ribs 3 intersecting within the frame 1. The vertical ribs 2 and horizontal ribs 3 are designed according to a general grid design. The upper part of the frame 1 is provided with a tab 4. Given that the current is large at the tab 4, the width and thickness of the frame 1 on the side close to the tab 4 are designed to gradually decrease to the other side to form a gradient grid outer edge 5. The side of the frame 1 with a larger width and thickness on the gradient grid outer edge 5 is the horizontal rib casting port 6. In a preferred embodiment, given the large current at the tab 4, the width and thickness of the vertical rib 2 gradually decrease from one end near the tab 4 to the other end, and the three vertical ribs 2 near the tab 4 are thickened vertical ribs 7 with a width and thickness greater than the width and thickness of the other vertical ribs 2, thereby effectively increasing the grid life. In a preferred embodiment, to facilitate the casting and molding of the entire grid, the width and thickness of the transverse rib 3 gradually decrease from one end near the casting port to the other.

[0014] In a preferred embodiment, since the gap between the vertical rib 2 and the edge of the frame 1 is relatively large, an auxiliary vertical rib 8 is provided in the gap to prevent the lead paste from falling off and to increase the strength of the grid.

[0015] In a preferred embodiment, the transverse rib 3 of this utility model includes a middle transverse rib 9 and upper transverse ribs 10 and lower transverse ribs 11 alternately arranged on both sides of the middle transverse rib 9. The upper transverse ribs 10 and lower transverse ribs 11 are distributed vertically, which can maintain high strength even when the cross-section of the transverse rib 3 is designed to be small.

[0016] In a preferred embodiment, the intermediate transverse rib 9 in this invention is a thickened rib, which helps to strengthen the grating.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
