[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0034] Please refer to Figures 1 to 3This utility model provides a clamping fixture for a square battery module, comprising: a first side fixing plate 1, a second side fixing plate 2, a first side pressing plate 4, a second side pressing plate 5, a first side clamping drive assembly 6, and a second side clamping drive assembly 7. The first side fixing plate 1 and the first side pressing plate 4 are arranged parallel to each other and spaced apart. The second side fixing plate 2 and the second side pressing plate 5 are arranged parallel to each other and spaced apart. The first side fixing plate 1, the second side fixing plate 2, the first side pressing plate 4, and the second side pressing plate 5 together form a cavity. The square battery module is placed in the cavity, ready for end plate clamping. The first side clamping drive assembly 6 is connected to the first side pressing plate 4, and the second side clamping drive assembly 7 is connected to the second side pressing plate 5. The first side clamping drive assembly 6 drives the first side pressing plate 4 to move, thereby causing the first side pressing plate 4 to clamp the first side of the square battery module. The second side clamping drive assembly 7 drives the second side pressing plate 5 to move, thereby causing the second side pressing plate 5 to clamp the second side of the square battery module.
[0035] Specifically, the first side clamping drive assembly 6 includes a push-pull seat 60, a cam 63, a first slider 61, and a first slide rail 62. One end of the push-pull seat 60 is fixedly connected to the first side pressure plate 4, and the other end of the push-pull seat 60 is movably connected to the cam 63. The push-pull seat 60 is fixed on the first slider 61, and the first slider 61 is slidably mounted on the first slide rail 62. When the cam 63 is rotated, different parts of the edge of the cam 63 contact the push-pull seat 60, thereby pushing the push-pull seat 60 to move towards the first side plate 1, realizing the first side clamping of the battery module. The first slider 61 slides along the first slide rail 62 with the push-pull seat 60. The first slider 61 ensures the stability and smoothness of the horizontal movement of the first side pressure plate 4, and will not deviate during the movement. This clamping fixture can replace the existing manual clamping, which not only saves effort but also allows for precise control of the clamping force.
[0036] The clamping fixture in this embodiment also includes a base plate 3. The first side plate 1 and the second side plate 2 are both rectangular plates of equal thickness. One side of the first side plate 1 is fixedly connected to the surface of the base plate 3, and one side of the second side plate 2 is also fixedly connected to the base plate 3. The first side plate 1 and the second side plate 2 are perpendicular to each other, and the base plate 3 is perpendicular to both the first side plate 1 and the second side plate 2. When clamping the end plate of the square battery module, the battery module is placed on the base plate 3.
[0037] In this embodiment, the first and second sides of the square battery module are perpendicular to each other. That is, the first side pressure plate 4 moves toward the first side fixing plate 1 and presses against the first side of the square battery module, and the second side pressure plate 5 moves toward the second side fixing plate 2 and presses against the second side of the square battery module. In this embodiment, the movement of the first side pressure plate 4 and the second side pressure plate 5 is horizontal, meaning that there is no vertical movement relative to the surface of the base plate 3.
[0038] Optionally, to strengthen the connection between the base plate 3 and the first side plate 1, a reinforcing block 8 is provided between the first side plate 1 and the base plate 3. The reinforcing block 8 is a right-angled triangular block, with its two right-angled sides respectively contacting the surfaces of the base plate 3 and the first side plate 1. The reinforcing block 8 and the base plate 3 can be fixed together by welding. Similarly, a reinforcing block 8 is also provided between the second side plate 2 and the base plate 3, with the same shape and arrangement as that between the first side plate 1 and the base plate 3.
[0039] Continue to refer to Figure 3 The first side clamping drive assembly 6 also includes a fixed frame 64, support plates 65, a rotating shaft 66, an elastic element 68, and a guide rod 67. The fixed frame 64 is fixed to the base plate 3 and is an L-shaped block. The fixed frame 64 is located on the outer side of the end of the first slide rail 62, and its end is connected to the end of the first slide rail 62. Two support plates 65 are respectively connected to the left and right sides of the fixed frame 64. The two support plates 65 are spaced apart and opposite to each other. Through holes are opened at the same height on both support plates 65. A rotating shaft 66 is inserted into the through holes of the two support plates 65, and the rotating shaft 66 can rotate relative to the support plates 65. A cam 63 is fixed to the rotating shaft 66 and is located between the two support plates 65. When the cam 63 is rotated, the cam 63 and the push-pull seat 60 can slide relative to each other, allowing different parts of the edge of the cam 63 to contact the push-pull seat 60, thereby pushing the push-pull seat 60.
[0040] To further ensure the stability and reliability of the push-pull seat 60 during movement, a circular guide hole is provided on the push-pull seat 60, which is opened along the direction of the first slide rail 62; a guide rod 67 is provided on the fixed frame 64. The guide rod 67 is a straight rod that is adapted to the guide hole. One end of the guide rod 67 is fixed to the fixed frame 64, and the other end of the guide rod 67 passes through the guide hole. When the push-pull seat 60 moves horizontally, the push-pull seat 60 can slide relative to the guide rod 67. The guide rod 67 plays a guiding role to prevent the push-pull seat 60 from deviating.
[0041] An elastic element 68 is also provided between the fixed frame 64 and the push-pull seat 60, which enables the push-pull seat 60 to automatically reset. In this embodiment, the elastic element 68 is a spring tube, which is sleeved on the outside of the guide rod 67. One end of the spring tube is fixed to the outer edge of the guide hole wall, and the other end of the spring tube is fixed to the fixed frame 64, so that the direction of the rebound force of the elastic element 68 is the same as the axial direction of the first slide rail 62, so as to facilitate the resetting of the push-pull block.
[0042] The cam 63 is also provided with a handle for easy gripping by the operator. During use, the operator holds the handle and rotates the cam 63, thereby pushing the first side pressure plate 4 to press the first side of the battery module. The handle of the cam 63 also has a through hole into which a limiting rod 631 is inserted. The fixing bracket 64 has a slot 641, the size of which matches the size of the limiting rod 631. The limiting rod 631 can be partially accommodated in the slot 641, thereby keeping different edges of the cam 63 in contact with the push-pull seat 60, achieving the pressing of square battery modules of different sizes. In this embodiment, the limiting rod 631 is a screw with a nut threaded onto it. When it is necessary to keep a certain edge of the cam 63 in contact with the push-pull seat 60, the nut is turned to fix the screw in the slot 641 of the fixing bracket 64.
[0043] refer to Figure 4 The second side pressure plate 5 is also connected to a second side pressing drive assembly 7, which includes a lead screw 70, a guide block 71, a pull rod 72, a second slide rail 73, and a second slider 74.
[0044] The pull rod 72 is L-shaped. One end of the pull rod 72 is connected to the second side plate 2, and the other end extends beyond the top side of the second side plate 2 and the second side pressure plate 5 to the outside of the second side pressure plate 5. The guide block 71 is fixed to the pull rod 72. The guide block 71 has a screw hole, and a lead screw 70 is threaded into the screw hole. The lead screw 70 can be threadedly connected to the guide block 71. Of course, the pull rod 72 and the second side plate 2 can be detachably connected to facilitate the placement of the battery module. For example, the pull rod 72 can be fixed to the second side plate 2 with screws.
[0045] One end of the lead screw 70 is connected to the second side pressure plate 5, and the other end of the lead screw 70 is connected to a turning handle. The turning handle is perpendicular to the lead screw 70 so that it is easier to turn the lead screw 70. At the same time, the lead screw 70 is perpendicular to the second side pressure plate 5.
[0046] In order to increase the contact area between the lead screw 70 and the second side pressure plate 5, a disc is connected to the end of the lead screw 70, and the disc is connected to the second side pressure plate 5.
[0047] The second slider 74 is slidably disposed on the second slide rail 73. The second slider 74 is located at the bottom of the second side pressure plate 5. The second side pressure plate 5 is fixedly connected to the second slider 74. When the second slider 74 moves, the second side pressure plate 5 also moves accordingly.
[0048] The second slide rail 73 is fixed on the base plate 3 and is perpendicular to the second side plate 2; of course, the first slide rail 62 is also fixed on the base plate 3 and is perpendicular to the second slide rail 73.
[0049] When it is necessary to press the second side of the battery module, turn the screw handle to rotate the lead screw 70. The lead screw 70 pushes the second side pressure plate 5 to move, thereby pressing the battery module on the second side. Of course, when it is necessary to remove the connected battery module, turn the lead screw 70 in the opposite direction to release the second side pressure plate 5 from the battery module.
[0050] The clamping fixture of this utility model replaces the current manual clamping method for the end plates of square battery modules, saving effort during clamping. Furthermore, the clamping force can be precisely controlled based on the position of the push-pull seat 60 on the first slide rail 62 and the position of the second slider 74 on the second slide rail 73. This clamping fixture can also clamp square battery modules of different sizes. Simply fixing the limiting rod 631 to different parts of the slot 641 keeps different edges of the cam 63 in contact with the push-pull seat 60, thus clamping square battery modules of different sizes. In addition, the clamping fixture can automatically reset the first side pressure plate 4 via the elastic element 68, accelerating disassembly. This clamping fixture is simple to operate, highly reliable, and stable.
[0051] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
