[0001] The utility model relates to the technical field of lead-acid battery protection, in particular to a valve-regulated lead-acid battery protection plate. Background Art

[0002] In the current field of battery protection technology, VRLA battery protection boards are crucial components for ensuring battery safety and extending battery life. Their performance and design rationality are directly related to the stable operation of the entire battery system. However, existing VRLA battery protection boards still have significant deficiencies in several areas, as shown below:

[0003] First, traditional VRLA battery protection boards are often fastened with bolts or welded. This design requires specialized tools for assembly and disassembly, making the operation complex and time-consuming. Furthermore, frequent tightening and loosening of bolts during assembly and disassembly can easily cause scratches, deformation, or even damage to the protection board or battery casing, impacting sealing and service life.

[0004] Furthermore, some protection boards have defects in their waterproof design, such as unreasonable sealing structure and rapid aging of sealing materials, which makes it difficult to effectively prevent moisture intrusion in actual applications. Once moisture penetrates the protection board, it will directly affect the performance and safety of the battery, and even cause serious problems such as short circuits and leakage. For this reason, we provide a valve-regulated lead-acid battery protection board. Utility Model Content

[0023] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0024] Example

[0025] like Figure 1-Figure 5As shown, an embodiment of the present invention proposes a valve-regulated lead-acid battery protection plate, wherein the protection plate is mainly composed of a U-shaped protection plate 1, an L-shaped protection plate 1 2, an L-shaped protection plate 2 3 and a lead-acid battery body 4 in the enclosed space surrounded by them. In order to facilitate disassembly and maintenance, a disassembly structure is specially designed between the L-shaped protection plate 1 2 and the L-shaped protection plate 2 3; the disassembly structure specifically includes: a plug-in plate 5 is fixedly connected to one end surface of the L-shaped protection plate 1 2, and a plug-in slot 6 that matches the plug-in plate 5 is provided on the upper end surface of the L-shaped protection plate 2 3. In order to ensure the stability of the plug-in and prevent accidental falling off, a limiting slot 7 is also provided on the inner end wall of the plug-in slot 6; a rectangular groove 8 is provided on the surface of the plug-in plate 5, and a lap plate 14 is slidably connected to the inner wall of this rectangular groove 8. A limiting plug plate 15 is fixedly connected to the surface of the connecting plate 14. When the connecting plate 5 is inserted into the connecting slot 6, the limiting plug plate 15 will be inserted into the inner wall of the limiting slot 7, thereby achieving a stable connection.

[0026] Among them, in order to make disassembly and assembly more convenient, a reset component is also connected between the rectangular groove 8 and the lap plate 14, so that when designing disassembly and assembly, only simple operations are needed to achieve a firm connection or easy separation between the plug-in board 5 and the plug-in slot 6; in order to protect the lead-acid battery body 4 from water seepage, a water-proof sealing component is also connected between the U-shaped protective plate 1, the L-shaped protective plate 1 2 and the L-shaped protective plate 2 3, thereby ensuring the waterproof performance of the entire enclosed space.

[0027] Furthermore, a strip-shaped receiving groove 9 is formed on the inner sidewall of the rectangular groove 8, and a cross-fixing rod 10 is fixedly connected to the center of the inner wall of this strip-shaped receiving groove 9. A partition 11 is fixedly connected between the end wall of the strip-shaped receiving groove 9 and one end surface of the cross-fixing rod 10. A spring 12 is sleeved around the outer periphery of this partition 11. At the same time, a movable sleeve 13 is slidably sleeved around the outer periphery of the partition 11. This movable sleeve 13 can slide on the inner wall of the strip-shaped receiving groove 9. The two ends of the lap plate 14 are fixedly connected to the opposing surfaces of the two movable sleeves 13. In this way, when the lap plate 14 is subjected to an external force, the movable sleeve 13 compresses the spring 12, achieving a reset function.

[0028] Furthermore, a sealing slot 16 is provided in the U-shaped protective plate 1. An L-shaped sealing insert 17 is fixedly connected to the inner wall of the L-shaped protective plate 2 3, and an L-shaped sealing insert 2 18 is fixedly connected to the inner wall of the L-shaped protective plate 1 2. Both L-shaped sealing inserts are inserted into the inner wall of the sealing slot 16 and form an interference fit with the sealing slot 16 to ensure a good sealing effect. Furthermore, a rubber base pad 19 is fixedly connected to the lower end of each L-shaped protective plate 2 3 to further enhance the sealing effect. Furthermore, heat dissipation holes 20 are provided on both sides of the U-shaped protective plate 1 to dissipate heat from the lead-acid battery body 4 during operation.

[0029] Furthermore, the plug-in board 5 is inserted into the inner wall of the insertion slot 6, achieving a preliminary connection between the L-shaped protective plate 1 2 and the L-shaped protective plate 2 3. Simultaneously, one end of the stopper board 15 penetrates the end wall of the rectangular groove 8 and is inserted into the inner wall of the stopper slot 7, further enhancing the connection stability between the plug-in board 5 and the insertion slot 6. To ensure that the stopper board 15 can be smoothly inserted into the stopper slot 7, the dimensions of the stopper slot 7 are adapted to the design dimensions of the rectangular groove 8.
