[0002] Currently, energy storage battery systems are used in a static state and do not face the same rigorous vibration conditions as power battery systems. Therefore, many energy storage battery boxes are easily fixed. However, the energy storage battery system will be transported before installation, and the bumps and vibrations during transportation often damage the structure of the energy storage battery box. Currently, the energy storage battery boxes on the market are mostly fixed by bolting the front of the battery box to the bracket, and the other parts of the battery box are only supported by the bracket. This structure cannot cope with the bumps and vibrations during transportation, and is likely to cause structural damage to the energy storage battery box or deformation of the fixing bracket, posing a safety hazard.

[0003] In order to solve the above problems, this application proposes a fixing mechanism for an energy storage battery box. Utility Model Content

[0007] As a further improvement of the present invention, the pressing plate is fixedly connected to the top of the limiting plate, and the pressing plate, the limiting plate and the horizontal plate are bent and formed as one piece.

[0008] As a further improvement of the present invention, a clamping bolt is threadedly connected to the clamping plate, and the clamping bolt thread is pressed against the top of the flange on the battery box.

[0009] As a further improvement of the present invention, a pad is provided between the flange and the pressing plate. The pad is fixedly connected to the top of the flange by bolts, and the pressing bolt threads are pressed against the pad.

[0010] As a further improvement of the present invention, a guide rod is fixedly connected to the side of the horizontal plate close to the limiting plate, and a first threaded hole is opened on the horizontal plate, and a limiting bolt is threadedly connected to the first threaded hole.

In addition, the terms "first", "second" and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The present invention will be further elaborated below in conjunction with specific implementation methods.

[0025] like Figure 1 、 Figure 2 As shown, the existing energy storage battery system is provided with a structure fixed by a third bolt 9 on the front side. A mounting structure and threaded holes matching the L-shaped guide rail 5 are reserved before the battery box 3 leaves the factory. The front end of the battery box 3 is fixed to the L-shaped guide rail 5 by the third bolt 9. There are only flanges 15 at the rest of the battery box 3. Considering that the flange 15 also has a sealing effect on the battery box 3, it is not easy to drill holes in the flange of the battery box 3. Since the energy storage battery system is used in a stationary state, the existing battery box 3 is often damaged by bumps and vibrations during transportation, which can easily cause structural damage to the energy storage battery box or deformation of the fixing bracket, posing a safety hazard.

[0026] Example 1

[0027] like Figure 3-Figure 5 As shown, it includes a base 1, a vertical support rod 2, a reinforcing beam 4, and an L-shaped guide rail 5. The reinforcing beam 4 is fixedly connected between the vertical support rods 2, and the L-shaped guide rail 5 is fixedly connected between the vertical support rods 2. A battery box 3 is installed on the top of the L-shaped guide rail 5, and the L-shaped guide rail 5 is composed of a horizontal plate 7 and a vertical plate 6. One end of the horizontal plate 7 is bent upward to form a limiting plate 11, and a clamping plate 8 for clamping the battery box 3 is provided near the limiting plate 11. The vertical plate 6 is used to install the L-shaped guide rail 5 and is fixedly connected to the vertical support rod 2. The horizontal plate 7 is used to support the battery box 3. The limiting plate 11 is used to limit from the rear when the battery box 3 is pushed in, and the battery box 3 is clamped and limited from the rear end by the clamping plate 8 to form a stable structure fixed front and back, thereby avoiding the damage to the structure of the battery box 3 caused by the vibration movement of the rear end during transportation caused by only fixing from the front end in the prior art, thereby improving safety.

[0028] In some optional embodiments, the pressing plate 8 is fixedly connected to the top of the limiting plate 11 , and the pressing plate 8 , the limiting plate 11 and the horizontal plate 7 are integrally bent and formed.

[0029] In some optional embodiments, a clamping bolt 10 is threadedly connected to the clamping plate 8, and the clamping bolt 10 is threadedly pressed on the top of the flange 15 on the battery box 3. The clamping bolt 10 is pressed on the flange 15 of the battery box 3, and there is no need to drill additional holes on the flange 15, and a clamping limit is provided at the rear end.

[0030] In some optional embodiments, a pad 18 is further provided between the flange 15 and the clamping plate 8. The pad 18 is fixedly connected to the top of the flange 15 by bolts, and the clamping bolt 10 is threadedly pressed on the pad 18. Optionally, the pad 18 is installed using the bolts on the flange 15. By adding the pad 18, it is possible to avoid the clamping bolt 10 being overtightened during installation and damaging the flange 15.

[0031] During installation, the battery box 3 is pushed into the energy storage system through the L-shaped guide rail 5. After the front end is fixed with the third bolt 9, the clamping bolt 10 is screwed in from the rear end.

[0032] Example 2

[0033] like Figure 6-Figure 8As shown, a guide rod 16 is fixedly connected to the side of the horizontal plate 7 close to the limit plate 11, and a first threaded hole 12 is opened on the horizontal plate 7, and a limit bolt 14 is threadedly connected to the first threaded hole 12. In addition, the height of the limit plate 11 can also be set to be flush with the top of the flange 15, so that the two ends of the clamping plate 8 can respectively abut against the top of the limit plate 11 and the flange 15, thereby avoiding deformation caused by unilateral force on the flange 15.

[0034] A guide hole matching the guide rod 16 is provided on the clamping plate 8 , a second threaded hole matching the limit bolt 14 is provided on the clamping plate 8 , the guide rod 16 passes through the clamping plate 8 , and the limit bolt 14 is threadedly connected and passes through the clamping plate 8 .

[0035] By rotating the limiting bolt 14 , the pressing plate 8 is lowered in the vertical direction and pressed against the flange 15 , thereby limiting the battery box 3 from both ends.

[0036] During installation, push the battery box 3 into the energy storage system through the L-shaped guide rail 5. After fixing the front end with the third bolt 9, first screw the limit bolt 14 into the clamping plate 8, and put the clamping plate 8 on the guide rod 16. Continue to screw the limit bolt 14 downward so that the limit bolt 14 is screwed into the first threaded hole 12 and the clamping plate 8 is pressed against the flange 15.
