It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0026] To address the issues of high workload and safety risks associated with disassembling battery packs in existing energy storage containers, this invention provides a mobile tooling that can directly move and disassemble problematic battery packs, thereby reducing the amount of disassembly work and improving disassembly safety.

[0027] The battery pack provided by this utility model is a battery pack with connecting ears, but it can also be other structures with connecting ears.

[0028] like Figures 1-3 As shown, the repair tooling of the energy storage container includes a frame 1, a clamping component, and a traveling mechanism. The traveling mechanism includes a fixed frame 2 and a moving structure 3. The moving structure 3 is mounted on the frame 1 and supported by the frame 1, while the fixed frame 2 is connected to the moving structure 3 and driven by the moving structure 3 to move in a straight line. The clamping component 4 is connected to the fixed frame 2 and can cooperate with the connection ears of the battery pack to grab the connection ears of the battery pack.

[0029] The mobile fixture provided by this utility model has a clamping component 4 that can cooperate with the connecting ear of the battery pack to grip the connecting ear. The clamping component 4 is connected to the fixed frame 2. After the clamping component 4 grips the connecting ear, the moving structure 3 drives the fixed frame 2 to move in a straight line. When the fixed frame 2 moves, the clamping component 4 will drive the battery pack to move accordingly to achieve the purpose of picking up and putting down the battery pack. Compared with the prior art, the fixture provided by this utility model only requires disassembling the battery pack with problems, which greatly reduces the workload of disassembly and is safer.

[0030] In other embodiments, the moving structure 3 includes a chain drive structure, which includes a motor, a chain, and two sprockets. The chain is wrapped around the sprockets and can move linearly as the sprockets rotate. The fixed frame 2 is fixed to the chain and can move with the chain. The motor is connected to the sprockets to drive the sprockets to rotate. In this way, the fixed frame 2 reciprocates under the action of the motor in both forward and reverse rotation.

[0031] In some embodiments, the movable structure 3 includes a motor, a lead screw, and a nut. The motor and the lead screw are connected by a coupling, the lead screw and the nut are threadedly connected, and the nut is fixedly connected to the fixed frame 2. In this way, the fixed frame 2 can move linearly with the nut.

[0032] For example, the moving structure includes a cylinder that directly pushes and pulls the fixing bracket 2 to realize the loading and unloading of the battery pack.

[0033] In some embodiments, the walking mechanism further includes an auxiliary sliding structure 5, which is disposed on both sides of the moving structure 3. The auxiliary sliding structure 5 can reduce the frictional force on the bottom of the battery pack, facilitating the movement of the battery pack and saving energy.

[0034] Specifically, the auxiliary sliding structure 5 includes a support 51 and rolling rollers 52. The rolling rollers 52 are rotatably arranged at intervals on the support 51. There are multiple rolling rollers 52, and the distance between adjacent rolling rollers 52 is less than the length of the battery pack. The arrangement direction of the rolling rollers 52 is the same as the moving direction of the moving structure 3. Since the auxiliary sliding structure 5 is located on both sides of the moving structure 3, when the battery pack is pulled, both ends of the battery pack are supported by the rolling rollers 52 and slide on the rolling rollers 52. At this time, the friction between the battery pack and the rolling rollers 52 is rolling friction, which is more labor-saving than the battery pack sliding directly on a plane. In addition, it can also prevent the bottom of the battery pack from being damaged by friction.

[0035] In some embodiments, combined with Figure 1 and Figure 6As shown, the mobile fixture also includes an auxiliary walking structure 6, which is located between the auxiliary sliding structure 5 and the moving structure 3. The auxiliary walking structure 6 is used to provide guidance for the connecting structure 2. The auxiliary walking structure 6 can provide guidance for the battery pack, prevent the battery pack from deviating during the movement, and ensure that the battery pack can move along the preset path.

[0036] Specifically, the auxiliary walking structure 6 includes a guide wheel 61 and a guide rail 62. The guide wheel 61 is rotatably fixed to the bottom of the fixed frame 2, and the guide rail 62 is disposed on the side of the auxiliary sliding structure 5 facing the connecting structure 2. The guide wheel 61 rotates along the extending direction of the guide rail 62. The guide rail 62 provides a predetermined movement trajectory for the guide wheel 61, thus the auxiliary walking structure 6 provides guidance for the movement of the fixed frame 2. In addition, the rotation of the guide wheel 61 relative to the fixed frame 2 makes the movement of the fixed frame 2 easier, thereby reducing the friction of the auxiliary walking structure 6.

[0037] Continue to refer to Figures 1-3 In some embodiments, the auxiliary sliding structure 5 is provided with a first limiting member 7 on the side opposite to the moving structure 3. The first limiting member 7 can prevent the battery pack from undergoing position correction during movement and prevent the battery pack from shifting during movement. Since the auxiliary sliding structure 5 is provided with a first limiting member 7 on the side opposite to the moving structure 3, both sides of the battery pack are provided with first limiting members 7. The distance between the first limiting members 7 on both sides of the battery pack is greater than the width of the battery pack, so as to ensure that the battery pack can move between the first limiting members 7.

[0038] Of course, to prevent the battery pack from slipping off the auxiliary sliding structure 5 after it is positioned on the auxiliary sliding structure 5, a detachable second limiting member 8 is provided on the side of the auxiliary sliding structure 5 facing the battery pack. When the battery pack is positioned on the auxiliary sliding structure 5, the second limiting member 8 is installed on the side of the auxiliary sliding structure 5 facing the battery pack to block the position of the battery pack and prevent it from slipping off. When the battery pack is sent back to its original position by the moving fixture, the second limiting member 8 needs to be removed so that the battery pack can be moved from the auxiliary sliding structure 5 to its original position and prevent the battery pack from being blocked.

[0039] In some embodiments, the clamping member 4 includes a connecting claw 41, which is detachably mounted on the fixing frame 2. The detachable structure adopts existing technology and will not be described in detail here. The connecting claw 41 can extend into the connecting ear of the battery pack and engage with the connecting ear. This allows the battery pack to be gripped without occupying space.

[0040] Furthermore, there are two connecting claws 41, which are arranged opposite to each other. One connecting claw 41 is fixedly mounted on the fixing frame 2, while the other connecting claw 41 is connected to the driving component. This ensures that the two connecting claws 41 can move closer or further apart. Specifically, the connecting claw 41 includes a connecting body 411 and a limiting hook 412. The limiting hook 412 is located on the sidewalls of the two connecting bodies 411 facing away from each other. The minimum distance H between the two limiting hooks 412 is less than the inner diameter of the connecting lug hole of the battery pack. This arrangement ensures that after the limiting hooks 412 approach each other to the minimum distance, the two connecting claws 41 can pass through the connecting lug hole. After the connecting claws 41 pass through the connecting lug hole, the two connecting claws 41 move away from each other until the connecting claws 41 contact the inner sidewall of the lug. At this point, the hook engages with the connecting lug hole, thereby achieving the purpose of connecting the fixing frame 2 to the battery pack through the connecting claws 41.

[0041] In some embodiments, the connector 411 has a certain elasticity to ensure that it can deform when passing through the connector ear hole, so that the connector limiting hook 412 can pass through the connector ear hole.

[0042] In some embodiments, such as Figure 4 As shown, the clamping component 4 also includes a driving component, which is connected to the connecting claw 41. The driving component is used to move the connecting claw 41 radially along the connecting ear. Exemplarily, the driving component includes a cylinder, which pushes and pulls the connecting claw 41 to move radially along the connecting ear, thereby achieving the purpose of locking the connecting claw 41 and the connecting ear, thus achieving the purpose of mutually limiting the connection between the connecting claw 41 and the connecting ear.

[0043] Of course, in other embodiments, the driving component includes a motor, a nut, and a lead screw. The driving end of the motor is connected to the lead screw via a coupling. The nut is threadedly connected to the lead screw and fixedly connected to the connecting claw 41. When the lead screw rotates, the nut moves linearly along the axial direction of the lead screw, thereby driving the connecting claw 41 to move linearly. The moving direction of the connecting claw 41 is perpendicular to the moving direction of the fixed frame 2. The driving component pushes and pulls the connecting claw 41 to move radially along the connecting ear, thereby achieving the purpose of locking the connecting claw 41 and the connecting ear. This achieves the purpose of mutually limiting the connection between the connecting claw 41 and the connecting ear.

[0044] Furthermore, to facilitate quick replacement of the battery pack, the clamping component 4 also includes a pusher 42 for moving the battery pack. The pusher 42 is detachably mounted on the mounting bracket 2 to allow for quick replacement of the connecting claw and the pusher 42. Additionally, the pusher 42 can directly push the connecting ear to prevent damage to the battery pack caused by the pusher 42 pushing other parts of the battery pack.

[0045] For example, the pushing member 42 includes a mounting block 421 and a protrusion 422 extending into the connecting ear. One end of the pushing member 42 is fixedly connected to the mounting block 71, and the other end of the mounting block 71 is detachably connected to the fixing frame 2. The detachable structure adopts existing technology and will not be described in detail here. The mounting block 71 has a protrusion 422 extending into the connecting ear at the end facing the battery pack. The protrusion 422 is a cylindrical structure. After the protrusion 422 extends into the connecting ear, the mounting block 71 abuts against the connecting ear. When it is necessary to push the battery pack back to its original position, the battery pack is first placed on the auxiliary sliding structure 5, and then the protrusion 422 is passed through the connecting ear and the mounting block 421 abuts against the connecting ear. The moving structure 3 works to move the battery pack back to the original position of the energy storage container. Then, the moving structure 3 is moved to disengage the connecting structure 2 from the battery pack, completing the push-back task.

[0046] This mobile fixture achieves lifting by moving the forks of a forklift. The frame 1 has insertion holes for the forks, located at the bottom of the frame 1. For example... Figure 7 As shown, specifically, the mobile fixture also includes two opposing position adjustment structures 9 located at the bottom of the frame 1. Each position adjustment structure 9 includes a tube 91 and an adjusting member 92. The tube 91 is used to insert a forklift rack, and the adjusting member 92 is positioned on either side of the tube 91 to adjust the position of the frame 1 relative to the rack. The cavity formed by the tube 91 is the insertion hole. The forklift rack is inserted into the tube 91, and then the position of the rack relative to the tube 91 is adjusted by the adjusting member 92. This allows for fine-tuning of the position of the tube 91 and the rack, thereby improving the positioning accuracy of the rework fixture and facilitating precise placement and removal of battery packs.

[0047] For example, the adjusting component 92 includes a fixed bending plate 921, a fixed plate 922, a horizontal adjusting bolt 923, and a vertical adjusting bolt 924. The insertion tube 91 is provided with a through hole 911 near the forklift. The through hole 911 is located on both sides of the insertion tube 91 to communicate with the chamber of the insertion tube 91. The two ends of the fixed bending plate 921 pass through the through hole 911 respectively. The fixed bending plate 921 is fixedly connected to the inner wall of the insertion tube 91. The fixed bending plate 921 includes a support plate 9211 and a bending plate 9212. The bending plate 921 is located at both ends of the support plate 941. The bending plate 921 is symmetrically arranged along the central axis of the short side of the support plate 941. The bending plate 921 has a threaded hole. In this way, the two bending plates 921 and the two horizontal adjusting bolts 923 are arranged one-to-one. The shelf located between the two horizontal adjusting bolts 923 can be adjusted in the horizontal direction within the insertion tube 91 to achieve the purpose of fine adjustment. The fixing plate 922 is positioned above the fixing bend plate 921, specifically fixed to the side wall of the insertion tube 91 facing the moving structure 3. The two ends of the vertical adjusting bolt 924 pass through the fixing bend plate 921 and the fixing plate 922 respectively. The distance between the fixing bend plate 921 and the fixing plate 922 is adjusted using the vertical adjusting bolt 924 to achieve fine-tuning of the shelf in the vertical direction. The position adjustment structure 9 can achieve six degrees of freedom of fine-tuning.

[0048] When using the mobile tooling, it is designed for battery packs with a width range of 800mm-810mm and features automatic width correction during battery pack handling. Compared to traditional containerized battery pack repair methods, it reduces workload by 50%, increases efficiency by 30%, and reduces the risk of damage to normal batteries and packs during repair by 90%.
