Detailed Description of the Invention

[0018] The following further describes the present application in detail Figures 1-5 with reference to the attached drawings.

[0019] An embodiment of the present application discloses a charging and discharging protection device for an energy storage battery, which includes a base 4. A seat body 1 is fixedly connected to the top of the base 4. A charging slot 2 and a discharging slot 3 are formed on the upper surface of the seat body 1. Conductive sheets 7 are fixedly connected to both sides of the charging slot 2 and the discharging slot 3. Inside the charging slot 2 and the discharging slot 3, a mounting seat 5 is connected through a lifting mechanism. The mounting seat 5 is used to load the battery, and insulating plates 15 are fixedly connected to both sides of the lower surface of the mounting seat 5. When the mounting seat 5 is at the top of the stroke of the lifting mechanism, the insulating plates 15 block the conductive sheets 7. When the mounting seat 5 is at the bottom of the stroke of the lifting mechanism, the positive and negative electrodes of the battery are in contact with the conductive sheets 7.

[0020] Further, slots 16 adapted to the insulating plates 15 are formed on both sides of the bottom surfaces of the charging slot 2 and the discharging slot 3, and the insulating plates 15 can be moved into or out of the slots 16.

[0021] Further, arc-shaped clamping plates 6 are fixedly connected to both sides of the upper surface of the mounting seat 5.

[0022] In this embodiment, by setting the lifting mechanism, the mounting seat 5 and the insulating plates 15 to cooperate, when loading and unloading the battery, the lifting mechanism can be used to move the mounting seat 5 to the top of the seat body 1. At this time, the insulating plates 15 block the surfaces of the conductive sheets 7. Therefore, during the installation or disassembly of the battery, the conductive sheets 7 are in a blocked state and the circuit is not connected, thereby improving the safety of installing or disassembling the battery. After loading the battery, the lifting mechanism is used to drive the mounting seat 5 to move down into the charging slot 2 and the discharging slot 3. At this time, the insulating plates 15 move into the slots 16 and no longer block the conductive sheets 7, and the positive and negative electrodes of the battery are in contact with the conductive sheets 7, thereby realizing the charging or discharging process of the battery.

[0023] In this embodiment, the arc-shaped clamping plates 6 have a certain toughness, and the top opening between the two groups of arc-shaped clamping plates 6 can be expanded under external force so that the battery can be placed between the two groups of arc-shaped clamping plates 6. After the external force disappears, the opening of the arc-shaped clamping plates 6 shrinks to fix the battery placed inside.

[0024] Further, the lifting mechanisms each include a vertical rod 9 fixedly installed on the lower surface of the mounting seat 5. Through holes 17 adapted to the vertical rods 9 are formed on the bottom surfaces of the charging slot 2 and the discharging slot 3. The lower end of the vertical rod 9 penetrates through the through hole 17 and is fixedly connected to a sliding sleeve 10. An active plate 12 is fitted inside the sliding sleeve 10. One end of the active plate 12 is fixedly connected to an insertion plate 14. A socket 13 is fixedly connected to the surface of the base 4, and the socket 13 is horizontally inserted and matched with the insertion plate 14. Springs 8 are sleeved on the surfaces of the vertical rods 9. The upper ends of the springs 8 are fixedly connected to the seat body 1, and the lower ends of the springs 8 are fixedly connected to the sliding sleeves 10. In the natural state, the springs 8 make the insulating plates 15 on the mounting seat 5 block the conductive sheets 7.

[0025] Further, the movable plate 12 is a horizontally arranged I-shaped structure. The notch of the sliding sleeve 10 matches the shape of the middle part of the movable plate 12, and a handle 11 is fixedly connected to the side of the movable plate 12 away from the plug board 14.

[0026] In this embodiment, when the plug board 14 is inserted into the socket 13, the spring 8 is in a stretched state, and the two mounting seats 5 are respectively located inside the charging slot 2 and the discharging slot 3. When a battery needs to be loaded, only need to pull the handle 11 to drive the movable plate 12 and the plug board 14 to move, so that the plug board 14 is removed from the socket 13, and the stretched spring 8 contracts accordingly, thereby driving the vertical rod 9, the mounting seat 5 and the insulating plate 15 to move upward, so that the insulating plate 15 covers the conductive sheet 7. After the battery is loaded, operate in reverse according to the above steps to make the mounting seat 5 move back to the inside of the charging slot 2 or the discharging slot 3, ensuring that the positive and negative electrodes of the battery are in contact with the conductive sheet 7, thereby realizing the charging and discharging process of the battery.
