[0053] With the large-scale development and utilization of the new energy market, battery energy storage has developed rapidly in recent years. From air-cooled to liquid-cooled modes, and from 1P52S to 1P104S, the capacity of individual battery packs has continuously increased, as has their weight. While this has reduced costs, it has also raised some new issues.

[0054] Taking the current 1P52S liquid-cooled battery pack as an example, a single battery weighs as much as 350kg. Without replacement equipment, it is almost impossible to maintain and replace the battery pack manually. In a factory environment, forklifts and other equipment can be used for disassembly and assembly. However, once the product is delivered to the project site, due to the limitations of the site terrain, replacement can only be done using a crane, which greatly increases the after-sales maintenance time and cost.

[0055] This invention addresses the shortcomings of existing technologies by providing a battery pack replacement device suitable for on-site battery pack replacement. This replacement device is simple in structure and easy to operate, allowing for the replacement of faulty battery packs manually without relying on external equipment, thus providing a more ideal solution for on-site battery pack replacement.

[0056] To address the problems existing in the prior art, this utility model provides a battery pack replacement device with a simple structure and convenient operation. It can replace faulty battery packs manually without relying on external equipment.

[0057] Please refer to Figure 1 The battery pack 50 replacement device provided in this embodiment of the utility model includes a top bracket 10, a battery tray 20, and an adjustment hanger 30.

[0058] The top support 10 includes two sets of symmetrically arranged booms 11, which are connected by one or more crossbeams 13; the booms 11 are provided with suspension parts 12 for connecting and adjusting the lifting device 30.

[0059] The battery tray 20 is equipped with a lifting ring 22 for lifting connection. By adjusting the connection between the lifting device 30 and the top bracket 10, the length of the lifting device 30 can be adjusted, thereby realizing the lifting and lowering of the battery tray 20.

[0060] By setting up a top bracket 10 and a battery tray 20, the top bracket 10 can be fixed on top of the battery cabinet 40, which is not limited by terrain and can achieve lifting action regardless of the type of foundation, greatly improving the applicability of the device.

[0061] Please refer to Figure 2 Specifically, the boom 11 includes a first inclined support rod 111, a second inclined support rod 112, and a vertical support rod 113. The first inclined support rod 111, the second inclined support rod 112, and the vertical support rod 113 form a triangular support structure, which has high stability and can ensure safety and reliability during the lifting and replacement of the battery pack 50.

[0062] The first end of the first inclined support rod 111 and the first end of the second inclined support rod 112 are connected together. The first end of the vertical support rod 113 is connected to the second end of the second inclined support rod 112, and the other end of the vertical support rod 113 is connected to the middle of the first inclined support rod 111.

[0063] The first inclined support rod 111 and the first vertical support rod 113 are both provided with suspension parts 12. The suspension part 12 includes two opposing limiting members, and the two limiting members form a groove for suspending and adjusting the lifting device 30. The aforementioned structure of the suspension part 12 is conducive to achieving stable suspension of the lifting device, further improving the flexibility and accuracy of operation.

[0064] Please refer to Figure 3 The battery tray 20 includes a tray base 21, on which a roller assembly 23 is mounted. The roller assembly 23 includes multiple rollers that are evenly distributed on the tray base 21. When replacing the battery pack 50, the battery pack 50 can be easily removed and installed, greatly improving the convenience of operation and reducing labor intensity.

[0065] Please refer to Figure 4 The battery tray 20 has a hollow section in the middle. The hollow section reduces the amount of material used in the battery tray 20, thereby reducing the total weight of the device. This makes it easier and more convenient to lift and move the battery tray 20 by adjusting the lifting device 30, and reduces the requirements for lifting equipment and operators.

[0066] In addition, during the replacement of the battery pack 50, the operator can more intuitively observe the position and status of the battery pack 50 through the cutout, which helps to accurately place the battery pack 50 on the roller assembly 23, and makes it easier to better control the operation progress when removing and installing the battery pack 50, thereby improving the accuracy and efficiency of the operation.

[0067] Furthermore, the roller assembly 23 is provided in two sets, and the two sets of roller assemblies 23 are symmetrically arranged on both sides of the hollow part.

[0068] The two sets of roller assemblies 23 are symmetrically arranged on both sides of the hollow part, so that the battery pack 50 is subjected to more even force on the tray. When the battery pack 50 is placed on the rollers, the rollers on both sides support the weight of the battery pack 50 together, reducing the situation of excessive local pressure and reducing the risk of damage to the battery pack 50.

[0069] Furthermore, the battery tray 20 is also provided with a lifting ring 22, which is connected to the tray base 21 via a connecting post 221.

[0070] Furthermore, the bottom of the battery tray 20 is provided with a bottom wheel 24, which is a universal wheel with a braking function, making it convenient to move and fix the battery tray 20 and improving the ease of operation.

[0071] Furthermore, in this embodiment, the length of the lifting device 30 is adjustable, which can adapt to the battery pack 50 replacement needs at different heights, thus improving the versatility of the device.

[0072] Specifically, the adjusting device 30 includes two implementation methods: a hydraulic telescopic rod and a spiral sleeve structure.

[0073] In one embodiment, the hydraulic telescopic rod includes an outer cylinder, an inner rod, and a hydraulic drive system. One end of the outer cylinder has a connecting portion that connects to the suspension portion 12. The inner rod is slidably disposed within the outer cylinder, and one end of the inner rod has a connecting structure for connecting to the lifting ring 22. The hydraulic drive system includes a hydraulic pump, a hydraulic valve, and connecting pipes. The hydraulic pump is connected to the hydraulic valve via the connecting pipes. The hydraulic valve controls the flow of hydraulic oil into or out of the space between the outer cylinder and the inner rod, thereby pushing the inner rod to extend and retract within the outer cylinder.

[0074] In another embodiment, the spiral sleeve structure includes an outer sleeve and an inner sleeve. The inner wall of the outer sleeve is threaded, and the outer wall of the inner sleeve is threaded to match the outer sleeve. One end of the outer sleeve is connected to the suspension part 12, and one end of the inner sleeve is connected to the lifting ring 22. By rotating the outer sleeve or the inner sleeve, the inner sleeve extends and retracts within the outer sleeve, thereby adjusting the length.

[0075] In order to facilitate the transmission of the battery pack 50 on the battery tray 20 during the battery pack 50 replacement operation, the battery pack 50 replacement device of this utility model also includes an auxiliary rope 25.

[0076] Please refer to Figures 5 to 7Specifically, the first end of the auxiliary rope 25 is used to fix a fixed point on the battery pack 50. A reversing roller 211 is rotatably provided on the tray base 21, and the reversing roller 211 is located at the unloading end of the battery pack 50. The reversing roller 211 has a rope winding part 2111 for winding the second end of the auxiliary rope 25, and also has a handle, which the operator drives the reversing roller 211 to rotate by operating the handle.

[0077] When the battery pack 50 needs to be moved, the operator turns the handle to drive the reversing roller 211 to wind around the second end of the auxiliary rope 25, thereby using the auxiliary rope 25 to drive the battery pack 50 to move on the battery tray 20, which further improves the convenience of operation.

[0078] Furthermore, the auxiliary rope 25 is fixedly connected to the battery pack 50 at two fixed points via the first fixing part 51 and the second fixing part 52, respectively. These two fixed points, together with the rope winding part 2111 of the reversing roller 211, form an isosceles triangle structure. This structural design makes the force distribution more uniform when the battery pack 50 is driven by the auxiliary rope 25, avoiding the battery pack 50 from shifting or shaking due to uneven force during transmission, ensuring the stability of the battery pack 50's movement, and helping to improve the accuracy of the replacement operation.

[0079] In addition, the tray base 21 is provided with two oppositely arranged mounting ears 213. A ratchet 212 is rotatably provided on the mounting ears 213, and a reversing roller 211 is located between the two mounting ears 213, with the ratchet 212 connected to both ends of the reversing roller 211.

[0080] Understandably, when the reversing roller 211 rotates forward under the drive of the handle, it can smoothly drive the auxiliary rope 25 to wind, thus realizing the transmission of the battery pack 50; when the battery pack 50 has a tendency to move in the opposite direction under the action of other external forces, the ratchet 212 can prevent the reversing roller 211 from rotating in the opposite direction, thereby preventing the battery pack 50 from moving in the opposite direction unexpectedly, ensuring the safety and reliability of the operation process.

[0081] In summary, the battery pack replacement device of this utility model has a simple structure, is easy to operate, and has strong applicability, providing a good solution for on-site battery pack replacement.

[0082] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
