Description

Technical Field

[0001] This utility model belongs to the field of battery assembly technology, specifically relating to a quick assembly tooling for lightweight power battery modules. Background Technology

[0002] Lightweight power battery modules are battery integration units designed specifically for lightweight applications. They are composed of multiple individual cells connected in series and parallel. They are equipped with an integrated battery management system to achieve real-time monitoring and equalization control of voltage and temperature. They adopt a high-strength lightweight frame and composite material shell to reduce structural weight. At the same time, they optimize heat dissipation paths and insulation design to improve safety. They have the advantages of high energy density, flexible assembly characteristics and lightweight design.

[0003] Patent application CN222462967U discloses a battery module assembly fixture. The fixture features symmetrically arranged side plates on a worktable with guide slots on the side plates. The modules can be moved forward and downward via rollers and a moving chain, facilitating the removal and unloading of the battery modules. Telescopic drive components are located above the mounting support plates. The output ends of the two telescopic drive components are connected to the clamping plate via a push plate and are located on the surface of the base between the two mounting support plates. By activating the two telescopic drive components, the battery modules are laterally squeezed to reach a specified range.

[0004] While this patent reduces the labor intensity of workers, it can only correct the two sides of the battery block during assembly, and cannot correct the other two sides. In actual use, although the baffle can achieve lateral alignment of the battery block, the battery block will move and deviate during the correction process, so the staff needs to manually correct the deviated battery block again, which reduces the assembly efficiency of the battery block. Summary of the Invention

[0005] In existing technologies, battery blocks can only be corrected on both sides during calibration, and the battery blocks may move or deviate during the calibration process, requiring manual correction by workers, which reduces the assembly efficiency of the battery blocks. To improve the above problems in existing technologies, a lightweight power battery module quick assembly tooling is provided.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A quick assembly fixture for a lightweight power battery module includes a worktable, a cross-shaped rotating block disposed below the worktable, and a first movable rod and a second movable rod symmetrically disposed between the cross-shaped rotating block and the worktable. The end of each first movable rod away from the cross-shaped rotating block is connected to a first moving block, and the end of each second movable rod away from the cross-shaped rotating block is connected to a second moving block. The ends of the two first moving blocks away from the first movable rods are each provided with a first frame, and the ends of the two second moving blocks away from the second movable rods are each connected to a second frame. A cylinder is rotatably connected inside both the first frame and the second frame.

[0008] Preferably, both the first movable rod and the second movable rod are connected to a slide rod at the end near the cross block and away from the worktable. Slide grooves are provided at the four ends of the cross block corresponding to the slide rods, and the slide rods are slidably connected in the slide grooves.

[0009] Preferably, the length of the second movable rod is greater than the length of the first movable rod, and the length of the first frame is less than the length of the second frame.

[0010] Preferably, the worktable has movable slots corresponding to the positions of the first movable block and the second movable block, and the first movable block and the second movable block are slidably connected in the movable slots.

[0011] Preferably, an adjustment block is provided between the first frame and the first moving block. The adjustment block is connected to the first moving block. A T-shaped groove is provided in the middle of the adjustment block. A T-shaped block is slidably connected in the T-shaped groove and is connected to the first frame.

[0012] Preferably, a housing is connected to one side of the adjusting block near the first moving block, and a plug rod is slidably connected inside the housing. The adjusting block has a slot corresponding to the position of the plug rod, and the T-shaped block has multiple evenly arranged slots corresponding to the position of the plug rod. The plug rod is inserted into the slot.

[0013] Preferably, an outer ring is connected to the outside of the insertion rod, the outer ring is located inside the outer shell, and a spring connects the outer ring and the outer shell.

[0014] The beneficial effects of this utility model are:

[0015] When assembling a lightweight power battery module, first place the module in the center of the workbench. After placement, start the motor, which drives the cross-shaped rotating block to rotate. During rotation, the cross-shaped rotating block simultaneously pulls four sliding rods, causing them to move synchronously and slide within the grooves. As they move, the four sliding rods pull their corresponding first and second movable rods. These rods, in turn, move a moving block within the movable slot. This movement of the moving block moves the corresponding first and second frames closer to the center of the workbench. The first and second frames, working in conjunction with the cylinder, align the lightweight power battery module with the center of the workbench and clamp it in place. Once aligned and secured, the module can be assembled. With all four sides aligned and secured, the assembly process is streamlined, eliminating the need for further adjustments and improving efficiency.

[0016] When adjusting the position of the first frame according to the proportion of the lightweight power battery module, the pull ring is pulled to move the insert rod out of the slot. When the insert rod moves out of the slot, it moves into the outer casing. The movement of the insert rod drives the outer ring to move, and the outer ring compresses the spring. The spring contracts under compression and stores restoring force. After the insert rod moves out of the slot, the T-block is no longer fixed to the first frame. By moving the first frame, the T-block can slide in the T-slot, and the position of the first frame can be adjusted. After the position of the first frame is adjusted, the pull ring is slowly released. Under the action of the spring's restoring force, the insert rod will be inserted into the slot, and the T-block will be fixed to the first frame again. This allows for the assembly of lightweight power battery modules with different proportions, improving compatibility. Attached Figure Description

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0030] Please see Figure 1 - Figure 6 As shown, a quick assembly fixture for a lightweight power battery module includes a worktable 1 for placing the lightweight power battery module.

[0031] A cross-shaped rotating block 2 is provided below the workbench 1. The cross-shaped rotating block 2 is used to pull or push the first movable rod 23 and the second movable rod 24 simultaneously.

[0032] A motor 3 is connected to the middle of the cross block 2 on the side away from the worktable 1. The motor 3 is used to drive the cross block 2 to rotate.

[0033] An L-shaped mounting plate 31 is connected to the lower surface of the workbench 1 at the position corresponding to the motor 3. The mounting plate 31 is used to support and fix the motor 3.

[0034] A first movable rod 23 and a second movable rod 24 are centrally symmetrically arranged between the cross-shaped rotating block 2 and the worktable 1. The first movable rod 23 and the second movable rod 24 are used to pull or push the first moving block 26 and the second moving block 261, respectively.

[0035] The length of the second movable rod 24 is greater than the length of the first movable rod 23. With this arrangement, the assembly ratio of multiple lightweight power battery modules can be better matched.

[0036] The first movable rod 23 and the second movable rod 24 are each connected to a slide rod 22 at a position near the cross rotating block 2 and away from the worktable 1. Each of the four ends of the cross rotating block 2 has a groove 21 corresponding to the position of the slide rod 22. The slide rod 22 is slidably connected in the groove 21. The groove 21 is used to provide the necessary movement space for the slide rod 22. The slide rod 22, in conjunction with the groove 21 and the cross rotating block 2, can pull or push the first movable rod 23 and the second movable rod 24.

[0037] Positioning blocks 25 are connected to the lower surface of the worktable 1 at the positions corresponding to the first movable rod 23 and the second movable rod 24, respectively. The first movable rod 23 and the second movable rod 24 are slidably connected in the positioning blocks 25, and the positioning blocks 25 are used to support and fix the positions of the first movable rod 23 and the second movable rod 24.

[0038] The first movable rod 23 is connected to a first movable block 26 at the end away from the cross-shaped rotating block 2, and the second movable rod 24 is connected to a second movable block 261 at the end away from the cross-shaped rotating block 2. The worktable 1 is provided with movable slots 27 corresponding to the positions of the first movable block 26 and the second movable block 261. The first movable block 26 and the second movable block 261 are slidably connected in the movable slots 27. The first movable block 26 is used to connect to the first frame 28, and the second movable block 261 is used to connect to the second frame 29. The movable slots 27 are used to provide the required range of motion for the first movable block 26 and the second movable block 261.

[0039] Each of the two first movable blocks 26 has a first frame 28 at the end away from the first movable rod 23, and each of the two second movable blocks 261 has a second frame 29 at the end away from the second movable rod 24. A cylinder 291 is rotatably connected inside the first frame 28 and the second frame 29. Through the cooperation of the first frame 28, the second frame 29 and the cylinder 291, when the first frame 28 and the second frame 29 are close to each other, the lightweight power battery module can be aligned to the center of the workbench 1 and clamped and fixed, thereby enabling the assembly of the lightweight power battery module. When aligning the lightweight power battery module, the cylinder 291 can reduce the friction between the lightweight power battery module and the first frame 28 and the second frame 29.

[0040] The length of the first frame 28 is less than the length of the second frame 29. This arrangement avoids mutual obstruction between the first frame 28 and the second frame 29 when calibrating the lightweight power battery module.

[0041] In practical use, when assembling a lightweight power battery module, first place the lightweight power battery module in the center of the workbench 1. After placement, start the motor 3. The motor 3 drives the cross-shaped rotating block 2 to rotate. During the rotation of the cross-shaped rotating block 2, it will synchronously pull the four sliding rods 22, causing the four sliding rods 22 to move synchronously and slide within the sliding groove 21. During the movement of the four sliding rods 22, they will respectively pull the corresponding first movable rod 23 and second movable rod 24. After the first movable rod 23 and second movable rod 24 move, they will respectively drive the first moving block 26 and the second moving block 261 to move within the movable groove 27. The movement of the second moving block 261 will drive the corresponding first frame 28 and second frame 29 to move closer to the center of the workbench 1. During the movement, the first frame 28 and second frame 29, together with the cylinder 291, can correct the light power battery module to the center of the workbench 1 and clamp and fix the light power battery module. After the light power battery module is corrected and fixed, the assembly work can be carried out. All four sides of the light power battery module are corrected and fixed, and the workers do not need to make adjustments again during assembly, which improves work efficiency and enables the assembly of light power battery modules more quickly.

[0042] After the lightweight power battery module is assembled, the motor 3 is restarted to reverse the motor. The reverse rotation of the motor 3 drives the cross-shaped rotating block 2 to reverse the motor, causing the cross-shaped rotating rod to push the sliding rod 22. With the cooperation of the first movable rod 23 and the second movable rod 24, the first frame 28 and the second frame 29 move synchronously away from the center of the workbench 1, thereby causing the assembled lightweight power battery module to lose its fixation, and the assembled lightweight power battery module can be removed from the workbench 1.

[0043] An adjustment block 4 is provided between the first frame 28 and the first moving block 26. The adjustment block 4 is connected to the first moving block 26 and is used to assist in adjusting the position of the first frame 28.

[0044] The adjusting block 4 has a T-shaped groove 41 in the middle, and a T-shaped block 42 is slidably connected in the T-shaped groove 41. The T-shaped block 42 is connected to the first frame 28. Through the cooperation of the T-shaped groove 41 and the T-shaped block 42, the movement position of the first frame 28 can be limited.

[0045] A housing 5 is connected to one side of the adjusting block 4 near the first moving block 26. The housing 5 is used to store the insertion rod 51.

[0046] A rod 51 is slidably connected inside the outer casing 5. A slot 52 is provided on the adjusting block 4 corresponding to the position of the rod 51. A plurality of evenly arranged slots 52 are provided on the T-shaped block 42 corresponding to the position of the rod 51. The rod 51 is inserted into the slot 52. Through the cooperation of the rod 51 and the slot 52, the position of the T-shaped block 42 and the first frame 28 can be fixed.

[0047] An outer ring 53 is connected to the outside of the insertion rod 51. The outer ring 53 is located inside the outer shell 5. A spring 54 is connected between the outer ring 53 and the outer shell 5. The spring 54 is used to reset the insertion rod 51.

[0048] The end of the insert rod 51 away from the adjusting block 4 passes through the housing 5 and is connected to the pull ring 55 on the outside of the housing 5. The pull ring 55 is used to remove the insert rod 51 from the slot 52.

[0049] In practical use, when the position of the first frame 28 needs to be adjusted according to the proportion of the lightweight power battery module, the pull ring 55 is pulled to move the insert rod 51 out of the slot 52. When the insert rod 51 moves out of the slot 52, it will move into the outer shell 5. The movement of the insert rod 51 drives the outer ring 53 to move. When the outer ring 53 moves, it will compress the spring 54. The spring 54 will contract and store the restoring force when compressed. After the insert rod 51 moves out of the slot 52, the T-shaped block 42 is no longer fixed to the first frame 28. By moving the first frame 28, the T-shaped block 42 can slide in the T-groove 41, and the position of the first frame 28 can be adjusted. After the position of the first frame 28 is adjusted, the pull ring 55 is slowly released. Under the action of the restoring force of the spring 54, the insert rod 51 will be inserted into the slot 52, and the T-shaped block 42 will be fixed to the first frame 28 again. This allows for the assembly of lightweight power battery modules with different proportions, improving adaptability.
