[0002] Since the energy people need is highly time- and space-dependent, in order to make rational use of energy and improve energy utilization, a device is needed to collect and store excess energy that is temporarily unused for a period of time, and then extract and use it during peak usage, or transport it to places where energy is scarce for use. This method is energy storage.

[0003] The fundamental task of an energy storage system is to overcome the temporal or localized differences between energy supply and demand. A battery energy storage system is a relatively common energy storage system, primarily consisting of a battery storage cabinet and various control devices. When assembling a battery storage cabinet, multiple battery packs are inserted into the cabinet's load-bearing rails, and then screwed into the front of the battery pack to secure it to the load-bearing rails. However, due to space constraints, once the battery pack is inserted into the load-bearing rails, the rear end becomes inoperable, preventing the rear end of the battery pack from being secured. This creates a gap between the rear end of the battery pack and the energy storage cabinet. During handling or transportation, the battery pack will vibrate violently due to this gap, which can easily cause damage to the battery pack and even lead to safety accidents. Utility Model Content

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, an automatic rear-end limiting mechanism for a battery pack of an energy storage system includes a cabinet body, a plurality of support columns 1 mounted therein, a plurality of battery pack support rails 2 evenly spaced on the support columns 1, a battery pack fixing screw hole 21 provided at the front end of the battery pack support rail 2, and a rear-end limiting member 3 provided at the rear end of the battery pack support rail 2, which is rotatably connected to the battery pack support rail 2. The battery pack 4 can slide on the battery pack support rail 2, and the rear end of the battery pack 4 can abut against one end of the rear-end limiting member 3, pushing the rear-end limiting member 3 to rotate in place on the battery pack support rail 2, thereby driving the other end of the rear-end limiting member 3 to abut against the upper end surface of the battery pack 4.

[0026] When installing the battery pack 4 into the cabinet, place the battery pack 4 on the battery pack supporting guide rail 2, and then push the battery pack 4 to slide on the battery pack supporting guide rail 2 so that the rear end of the battery pack 4 is connected with the rear end limit member 3; as the battery pack 4 continues to be pushed in, the battery pack 4 will push the rear end limit member 3 to rotate until the other end of the rear end limit member 3 abuts against the upper end surface of the battery pack 4, and at this time, the screw hole at the front end of the battery pack 4 is also exactly aligned with the battery pack fixing screw hole 21, and then the front end of the battery pack 4 is connected and fixed to the battery pack supporting guide rail 2 by screwing in the fixing screw, and the installation of the battery pack 4 is completed.

[0027] The energy storage system battery pack rear end automatic limiting mechanism is able to automatically limit the rear end of the battery pack 4 by setting a rear end limiting member 3, and then by installing a fixing screw on the battery pack fixing screw hole 21, the front end of the battery pack 4 is connected and fixed to the battery pack bearing guide rail 2, thereby fixing the battery pack 4 on the battery pack bearing guide rail 2; the front and rear ends of the battery pack 4 are respectively limited by the fixing screw and the rear end limiting member 3, thereby preventing the battery pack 4 from shaking due to the gap on the battery pack bearing guide rail 2, and solving the problem of damage to the battery pack 4 or safety accidents during handling and transportation of the battery pack 4.

[0028] Specifically, a rotating shaft 5 is provided on the battery pack carrying guide rail 2, and the rear end limit member 3 is rotatably connected to the rotating shaft 5; the rear end limit member 3 is hinged and limited to the battery pack carrying guide rail 2 through the rotating shaft 5. In the process of pushing the battery pack 4 into the battery pack carrying guide rail 2, the rear end of the battery pack 4 can push the rear end limit member 3 to rotate along the axis of the rotating shaft 5, so that the other end of the rear end limit member 3 abuts against the upper end surface of the battery pack 4, thereby realizing the limiting function of the rear end surface and the upper end surface of the battery pack 4 at the same time.

[0029] The battery pack support rail 2 includes a sliding plate 22 and a mounting plate 23. The mounting plate 23 is fixedly connected to the support column 1 via bolts. The rotating shaft 5 is mounted on the mounting plate 23, thereby hingedly mounting the rear end stopper 3 on the mounting plate 23. The battery pack 4 is placed on the sliding plate 22 and can be pushed to slide on the sliding plate 22. The battery pack fixing screw hole 21 is set at the front end of the sliding plate 22. When installing the battery pack 4, the battery pack 4 is placed on the sliding plate 22 and pushed to slide on the sliding plate 22. The rear end of the battery pack 4 will contact one end of the rear end stopper 3. As the battery pack 4 is further pushed in, the battery pack 4 will push the rear end stopper 3 to rotate along the axis of the rotating shaft 5 until the other end of the rear end stopper 3 abuts the upper end surface of the battery pack 4. At this time, the front and rear screw holes of the battery pack 4 are exactly aligned with the battery pack fixing screw hole 21 on the sliding plate 22. The front end of the battery pack 4 is then connected and fixed to the sliding plate 22 by screwing in the fixing screw. At this time, the front end of the battery pack 4 is fixed by the fixing screws, and the rear end is fixed by the rear end limiter 3, thereby achieving the purpose of fixing the battery pack 4 to the battery pack supporting guide rail 2, avoiding the battery pack 4 from shaking during transportation or handling.

[0030] In this embodiment, the sliding plate 22 and the mounting plate 23 are integrally formed, and are formed by bending a single piece of sheet material to form the sliding plate 22 and the mounting plate 23. In other embodiments, the sliding plate 22 and the mounting plate 23 may be two separate components, which may be connected and fixed by welding, screwing, or the like.

[0031] In order to facilitate the installation of the front-end fixing screws, an avoidance groove 24 is provided on the mounting plate 23 at a position corresponding to the battery pack fixing screw hole 21; the avoidance groove 24 provides operating space for the use of installation tools when fixing the front-end fixing screws of the battery pack 4, avoids interference, reduces the difficulty of installing the battery pack 4, and improves efficiency.

[0032] The rear end stopper 3 includes a battery pack rear end surface stopper 31 and a battery pack upper end surface stopper 32, respectively disposed on either side of the rotation axis 5. The battery pack rear end surface stopper 31 is capable of abutting the rear end surface of the battery pack 4, while the battery pack upper end surface stopper 32 is capable of abutting the upper end surface of the battery pack 4. The mass of the battery pack rear end surface stopper 31 is greater than the mass of the battery pack upper end surface stopper 32. By setting the mass of the battery pack rear end surface stopper 31 to be greater than the mass of the battery pack upper end surface stopper 32, the battery pack rear end surface stopper 31 of the rear end stopper 3 faces downward when the battery pack 4 is not present. This allows the rear end of the battery pack 4 to engage the rear end stopper 3 when the battery pack 4 is pushed onto the sliding plate 22, forcing the rear end stopper 3 to rotate along the rotation axis 5, thereby automatically limiting the rear end of the battery pack 4.

[0033] A first protective block 33 is provided on the end face of the battery pack rear end stop 31, away from the rotation axis 5. A second protective block 34 is provided on the end face of the battery pack upper end stop 32, away from the rotation axis 5. The first protective block 33 protects the rear end face of the battery pack 4, while the second protective block 34 protects the upper end face of the battery pack 4. This reduces the possibility of damage or scratches to the battery pack 4, improving practicality.

[0034] In this embodiment, the first protective block 33 and the second protective block 34 are both made of rubber material; in other embodiments, the first protective block 33 and the second protective block 34 may also be made of other flexible materials.

[0035] The battery pack carrying guide rail 2 is provided with a guide member 6, and the rear end limit member 3 is slidably connected to the guide member 6. By providing the guide member 6, the direction of the rear end limit member 3 during rotation can be limited and guided, thereby improving the stability and accuracy of the rotation.

[0036] In this embodiment, the guide member 6 includes a fixed end 61 and a bending guide portion 62. The fixed end 61 is connected to the battery pack support rail 2, and the bending guide portion 62 is sleeved on the periphery of the rear end limit member 3 and slides with the rear end limit member 3. Specifically, during the installation process, rivets are used to fix the fixed end 61 to the mounting plate 23, thereby fixing the guide member 6 to the battery pack support rail 2 and sleeved on the periphery of the rear end limit member 3. During use, the rear end limit member 3 rotates within the bending guide portion 62, and the bending guide portion 62 limits the rotation direction of the rear end limit member 3, so that the battery pack rear end face limit portion 31 can abut against the rear end of the battery pack 4, and also enables the battery pack upper end face limit portion 32 to abut against the upper end face of the battery pack 4, thereby achieving the limiting function of the battery pack 4.

[0037] The above-mentioned specific implementation manner is a preferred implementation manner of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation manner. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
