[0053] With the large-scale development and utilization of the new energy market, battery energy storage has developed rapidly in recent years. From air cooling mode to liquid cooling mode, from 1P52S to 1P104S, the capacity of a single battery pack continues to increase, and the weight continues to increase. This has reduced costs while also causing some new problems.

[0054] Taking the current 1P52S liquid-cooled battery pack as an example, the weight of a single battery is as high as 350kg. In the absence of replacement equipment, it is almost impossible to maintain and replace the battery pack by manpower alone. In a factory environment, disassembly and assembly operations can be completed with the help of forklifts and other equipment. However, when the product is delivered to the project site, it can only be replaced by a crane due to the limitations of the site terrain, which greatly increases the after-sales maintenance time and cost of the product.

[0055] The present invention aims at the deficiencies in the prior art and provides a replacement device suitable for on-site replacement of battery packs. The replacement device has a simple structure and is easy to operate. It can replace a faulty battery pack only by manpower without relying on external equipment, providing a relatively ideal solution for on-site replacement of battery packs.

[0056] In order to solve the problems existing in the prior art, an embodiment of the present invention provides a battery pack replacement device with a simple structure and easy operation. A faulty battery pack can be replaced only by manpower without relying on external equipment.

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

[0058] The top support 10 includes two groups of symmetrically arranged booms 11 , and the two groups of booms 11 are connected by one or more cross beams 13 ; a hanging portion 12 is provided on the boom 11 for connecting and adjusting the hanger 30 .

[0059] The battery tray 20 is provided with a lifting ring 22 for lifting connection, and is connected to the top bracket 10 by adjusting the lifting device 30. The length of the adjusting lifting device 30 is adjustable, so that the battery tray 20 can be raised and lowered.

[0060] By providing the top bracket 10 and the battery tray 20, the top bracket 10 can be fixed on the top of the battery cabinet 40 without being restricted by the terrain. The lifting action can be achieved regardless of the form of the foundation, which greatly improves 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 with high stability, which can ensure safety and reliability during the process of lifting and replacing the battery pack 50.

[0062] The first end of the first inclined support rod 111 is connected to the first end of the second inclined support rod 112 , 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 second end of the first inclined support rod 111 and the first end of the vertical support rod 113 are both provided with a hanging portion 12, and the hanging portion 12 includes two opposite limiting members, and a groove portion for hanging and adjusting the sling 30 is formed between the two limiting members. The aforementioned structure of the hanging portion 12 is conducive to achieving stable suspension of the sling, and further improves the flexibility and accuracy of operation.

[0064] Please refer to Figure 3 The battery tray 20 includes a tray base 21, and a roller assembly 23 is provided on the tray base 21. The roller assembly 23 includes a plurality of rollers, and the plurality of rollers are evenly distributed on the tray base 21. When the battery pack 50 is replaced, the battery pack 50 can be easily extracted and installed, which greatly improves the convenience of operation and reduces the labor intensity.

[0065] Please refer to Figure 4 A hollow portion is provided in the middle of the battery tray 20. The hollow portion reduces the overall material usage of the battery tray 20, thereby reducing the total weight of the device, making it easier and more convenient to adjust the lifting device 30 for lifting or moving the battery tray 20, thereby reducing the requirements for lifting equipment and operators.

[0066] In addition, during the process of replacing the battery pack 50, the operator can more intuitively observe the position and status of the battery pack 50 through the hollow portion, which helps to accurately place the battery pack 50 on the drum assembly 23, and facilitates better control of the operation progress when pulling out and installing the battery pack 50, thereby improving the accuracy and efficiency of the operation.

[0067] Furthermore, two groups of roller assemblies 23 are provided, and the two groups of roller assemblies 23 are symmetrically arranged on both sides of the hollow portion.

[0068] The two groups of roller assemblies 23 are symmetrically arranged on both sides of the hollow part so that the force on the battery pack 50 on the tray is more uniform. When the battery pack 50 is placed on the rollers, the rollers on both sides jointly support the weight of the battery pack 50, 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 , and the lifting ring 22 is connected to the tray base 21 through a connecting column 221 .

[0070] Furthermore, a bottom wheel 24 is provided at the bottom of the battery tray 20. The bottom wheel 24 is a universal wheel with a brake function, which facilitates the movement and fixation of the battery tray 20 and improves the convenience of operation.

[0071] Furthermore, in the present embodiment, the length of the adjustment hanger 30 is adjustable, which can meet the replacement requirements of battery packs 50 of different heights, thereby improving the versatility of the device.

[0072] Specifically, the adjustment hanger 30 includes two implementation modes: a hydraulic telescopic rod and a spiral sleeve structure.

[0073] In one embodiment, the hydraulic telescopic rod includes an outer tube, an inner rod and a hydraulic drive system. One end of the outer tube is provided with a connection portion connected to the suspension portion 12, the inner rod is slidably arranged in the outer tube, and one end of the inner rod is provided with a connection structure for connecting to the lifting ring 22. The hydraulic drive system includes a hydraulic pump, a hydraulic valve and a connecting pipeline. The hydraulic pump is connected to the hydraulic valve through the connecting pipeline. The hydraulic valve controls the hydraulic oil to flow into or out of the space between the outer tube and the inner rod, thereby pushing the inner rod to extend and retract in the outer tube.

[0074] In another embodiment, the spiral sleeve structure includes an outer sleeve and an inner sleeve. The inner wall of the outer sleeve is provided with a thread, and the outer wall of the inner sleeve is provided with a thread matching the outer sleeve. One end of the outer sleeve is connected to the hanging portion 12, and one end of the inner sleeve is connected to the hanging ring 22. By rotating the outer sleeve or the inner sleeve, the inner sleeve is extended and retracted in the outer sleeve, thereby achieving length adjustment.

[0075] During the battery pack 50 replacement operation, in order to facilitate the transmission of the battery pack 50 on the battery tray 20, the battery pack 50 replacement device of the present invention 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 be connected to 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 arranged at the unloading end of the battery pack 50. The reversing roller 211 is provided with a rope winding portion 2111 for winding the second end of the auxiliary rope 25, and is also provided with a handle, and 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 up the second end of the auxiliary rope 25 , thereby using the auxiliary rope 25 to drive the battery pack 50 to be transmitted on the battery tray 20 , further improving the convenience of operation.

[0078] Furthermore, the auxiliary rope 25 is fixedly connected to the first fixing portion 51 and the second fixing portion 52 on the battery pack 50 to form two fixing points, and the two fixing points and the rope winding portion 2111 of the reversing roller 211 form an isosceles triangle structure. This structural design makes the force distribution more uniform when the auxiliary rope 25 is used to drive the battery pack 50 to transmit, avoids the battery pack 50 from deflecting or shaking due to uneven force during the transmission process, ensures the stability of the movement of the battery pack 50, and helps to improve the accuracy of the replacement operation.

[0079] In addition, the tray base 21 is provided with two mounting ears 213 disposed opposite to each other. A ratchet 212 is rotatably provided on the mounting ears 213, and the reversing roller 211 is disposed between the two mounting ears 213, and the two ends of the reversing roller 211 are connected to the ratchet 212 respectively.

[0080] It can be understood that when the reversing roller 211 rotates forwardly under the drive of the handle, it can smoothly drive the auxiliary rope 25 to wind, thereby realizing the transmission of the battery pack 50; and when the battery pack 50 tends 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 accidentally moving in the opposite direction, thereby ensuring the safety and reliability of the operation process.

[0081] In summary, the battery pack replacement device of the present invention has a simple structure, is easy to operate, and has strong applicability, and provides a better solution for on-site replacement of battery packs.

[0082] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
