Description

Technical Field

[0001] This utility model relates to the field of battery box technology, specifically to an energy storage battery box. Background Technology

[0002] An energy storage battery box is an integrated energy storage device that integrates multiple battery modules and a battery management system (BMS) into a sealed storage box. The battery modules are typically lithium-ion batteries (such as lithium iron phosphate batteries) or sodium-ion batteries, and are constructed by connecting them in series and parallel to form battery module units that meet specific voltage and capacity requirements.

[0003] However, some existing energy storage battery boxes (such as certain discharge battery designs) have safety hazards: their discharge electrodes are usually directly exposed, and although a certain distance is maintained between the two electrodes, there is a lack of effective protective structure. This design is highly susceptible to short circuits during transportation or storage due to accidental contact, intrusion of conductive foreign objects, or environmental factors, which can lead to equipment damage or even safety accidents. Therefore, an improved energy storage battery box is needed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide an energy storage battery box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy storage battery box, including a battery housing, a battery disposed inside the battery housing, electrodes fixedly disposed on both sides of the upper end of the battery housing, and a protective mechanism for isolating the electrodes disposed on the surface of the battery housing outside the electrodes. The protective mechanism includes a fixing ring, an L-shaped groove, a spring, a protective sleeve, and a limiting rod. A fixing ring is fixedly disposed on the surface of the battery housing outside the electrodes, and an L-shaped groove is formed on the surface of the fixing ring. A spring is disposed at the upper end of the electrodes, and a protective sleeve is disposed at the upper end of the spring. Limiting rods are fixedly disposed on both sides of the surface of the protective sleeve. The upper end of the spring is fixedly connected to the protective sleeve, and the lower end of the spring is fixedly connected to the electrodes. Figure 6 As shown, the spring of this device is in a compressed state. As long as the limiting rod is not engaged at the corner of the L-shaped slot, but aligned with the notch of the L-shaped slot, it will work. Figure 5 The spring shown can automatically spring back to its original position, causing the protective sleeve to move upward, thereby exposing the electrodes for easy electrical connection.

[0006] Preferably, a sealing ring is fixedly provided on the outer surface of the lower end of the electrode, and a chamfer is provided on the lower end of the inner sidewall of the protective sleeve. When the protective sleeve moves down, it will be interference-fitted onto the outer surface of the sealing ring, which can ensure the sealing between the protective sleeve and the sealing ring, thus further improving the isolation and protection effect of the device on the electrode; and the chamfer is to facilitate the protective sleeve to be fitted onto the outside of the sealing ring.

[0007] Preferably, an annular groove is provided on the outer side of the electrode, and a through groove is provided in the middle of the annular groove. The annular groove allows for easy connection of clips, while the through groove allows for easy connection of wires. This facilitates the charging and discharging of the device through the electrode.

[0008] Preferably, the protective sleeve, spring, and sealing ring are all made of non-conductive materials. The protective sleeve and spring can be made of plastic, or the spring can be made of metal coated with insulating varnish, while the sealing ring can be made of rubber.

[0009] Preferably, the electrode is electrically connected to the battery, and the electrode can help the battery to charge and discharge.

[0010] Preferably, a heat dissipation fin plate is fixedly provided on the outside of the battery casing. The heat dissipation fin plate can increase the contact area between the device and the external environment, thereby improving the natural heat dissipation effect of the device.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model adds an additional protective mechanism to the outside of the electrode, such as... Figure 6 As shown, the spring of this device is in a compressed state. As long as the limiting rod is not engaged at the corner of the L-shaped slot, but aligned with the notch of the L-shaped slot, it will work. Figure 5 The spring shown can automatically spring back to its original position, causing the protective sleeve to move upwards, thus exposing the electrodes for easy electrical connection. This significantly improves the safety of the device when batteries are not needed or during battery transport, preventing short circuits.

[0013] 2. When the protective sleeve moves down, it will be interference-fitted onto the outer surface of the sealing ring, which can ensure the sealing between the protective sleeve and the sealing ring, thus further improving the isolation and protection effect of the device on the electrode.

The upper end of the electrodes 3 is disposed on the spring 6, and the upper end of the spring 6 is disposed on the protective sleeve 7. Limiting rods 8 are fixedly disposed on both sides of the surface of the protective sleeve 7. The upper end of the spring 6 is fixedly connected to the protective sleeve 7, and the lower end of the spring 6 is fixedly connected to the electrodes 3. Figure 6 As shown, the spring 6 of this device is in a compressed state. As long as the limiting rod 8 is not engaged at the corner of the L-shaped groove 5, but aligned with the notch of the L-shaped groove 5, it will work. Figure 5 The spring 6 shown can automatically spring back to its original position, causing the protective sleeve 7 to move upward, thereby exposing the electrode 3 for convenient electrical connection.

[0023] A sealing ring 9 is fixedly provided on the outer surface of the lower end of the electrode 3, and a chamfer is provided on the lower end of the inner side wall of the protective sleeve 7. When the protective sleeve 7 moves down, it will be interference-fitted onto the outer surface of the sealing ring 9, which can ensure the sealing between the protective sleeve 7 and the sealing ring 9, thus further improving the isolation and protection effect of the device for the electrode 3; and this chamfer is to facilitate the fitting of the protective sleeve 7 onto the outside of the sealing ring 9.

[0024] An annular groove 10 is provided on the outer side of the electrode 3, and a through groove 11 is provided in the middle of the annular groove 10. The annular groove 10 can be used to easily connect clips, and the through groove 11 can be used to easily connect wires.

The protective sleeve 7 and spring 6 can be made of plastic materials, or the spring 6 can be made of metal material coated with insulating paint, while the sealing ring 9 can be made of rubber materials.

[0026] The electrode 3 is electrically connected to the battery, and the electrode 3 can help the storage battery 2 to charge and discharge.

[0028] Working principle: When using this device, an additional protective mechanism is added to the outside of electrode 3, such as... Figure 6 As shown, the spring 6 of this device is in a compressed state. As long as the limiting rod 8 is not engaged at the corner of the L-shaped groove 5, but aligned with the notch of the L-shaped groove 5, it will work.
