[0002] An automotive battery pack is an energy storage device composed of multiple battery cells connected in series and parallel, and integrated with key components such as a battery management system and a thermal management system. As one of the core components of modern electric vehicles, its quality is related to the overall performance of the vehicle. Therefore, in the existing technology, before assembling the automotive battery pack with other automotive components, a corresponding template tool is usually used for testing. That is, the gap between the surface of the automotive battery pack and the template tool is measured to determine whether the shape of the automotive battery pack meets the requirements.

[0003] However, in the traditional inspection fixtures currently in use, the surface inspection point inspection mechanism is designed as a flip-up template knife. In actual use, it is necessary to frequently open and lock the template knife to adapt to the inspection requirements of different positions according to the different surface structures of the car battery pack. The operation is not only troublesome, but also prolongs the inspection time and reduces the inspection efficiency. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 A vehicle battery pack testing device includes a testing platform 1 and a battery pack body 2 set on top of the testing platform 1. Several clamps 12 are installed on the top of the testing platform 1 to press and limit along the side of the battery pack body 2. A testing frame 3 that can be movably connected to the battery pack body 2 is slidably installed on the top of the testing platform 1, and a lifting platform 4 is slidably installed on the top of the testing frame 3. The output structure of the lifting platform 4 is connected to a template knife 5. The lifting platform 4 includes a platform frame 41, a lead screw 42, a brake servo motor 43, a nut 44, and a linkage rod 45. The rear end of the platform frame 41 is clamped to a second slide rail 11 fixed to the front end of the top of the testing frame 3. One end of the lead screw 42 passes through the top structure of the platform frame 41 and is connected to the output end of the brake servo motor 43 installed on the top of the platform frame 41. The nut 44 is movably sleeved inside the platform frame 41 and threadedly connected to the surface of the lead screw 42. The two ends of the linkage rod 45 pass through the bottom structure of the platform frame 41 and are fixed to the top of the template knife 5, respectively.

[0023] A first positioning component is provided between the rear end of the platform frame 41 and the top of the detection frame 3. The first positioning component includes a second L-shaped positioning plate 13 and a second electromagnet 14. The front end of the second L-shaped positioning plate 13 is fixed to the rear end of the platform frame 41. The second electromagnet 14 is installed at the bottom of the second L-shaped positioning plate 13 and can magnetically connect to the top surface of the detection frame 3, thereby ensuring the stability of the lifting platform 4 and the template knife 5 after adjustment. A first electromagnet 46 is fixedly nested on one side of the platform frame 41. A flat groove is opened on the surface of the nut 44, and the surface of the flat groove can fit and connect with the magnetic surface of the first electromagnet 46, thereby improving the stability of the nut 44 after lifting and adjustment. There are no fewer than two linkage rods 45, which are arranged along the circumference of the nut 44 to ensure the subsequent transmission strength. A bearing is nested at the fitting point between the lead screw 42 and the platform frame 41 to reduce the friction loss between the lead screw 42 and the platform frame 41 and improve the service life.

[0024] In use, to adjust the distance between the template blade 5 and the top surface of the battery pack body 2, the brake servo motor 43 inside the lifting platform 4 is turned on. The output end of the brake servo motor 43 drives the lead screw 42 to rotate synchronously. The rotated lead screw 42 will engage the transmission nut 44, so that the nut 44 drives the template blade 5 to move up and down synchronously through the linkage rod 45 until the distance between the template blade 5 and the battery pack body 2 reaches the usage requirement.

[0025] To ensure the stability of the template knife 5 after adjustment, the first electromagnet 46 is turned on, and the magnetic surface of the first electromagnet 46 magnetically attracts and limits the nut 44, thus fully ensuring the stability of the template knife 5 in subsequent use.

[0026] To address the lateral displacement of the lifting platform 4 and the template knife 5, first turn off the second electromagnet 14 to temporarily release its magnetic attraction limit on the detection frame 3. Then, push the lifting platform 4 to move the template knife 5 along the top structure of the detection frame 3 until it reaches the appropriate position. After completion, restart the second electromagnet 14 to restore its magnetic attraction limit on the detection frame 3.

[0027] Please see Figures 1-3 The bottom of the detection frame 3 is snapped with a first slide rail 10 fixed to the top surface of the detection platform 1, and the first slide rail 10 has a countersunk hole inside. The top of the detection platform 1 has a positioning screw hole that can be aligned with the countersunk hole, and a screw that can be threadedly connected to the positioning screw hole is fitted inside the countersunk hole, so that the first slide rail 10 and the detection platform 1 can be detachably installed.

[0028] In use, the detection frame 3 can be moved back and forth along the top of the detection platform 1, and the bottom of the detection frame 3 is engaged with the first slide rail 10 to provide guidance and support for the movement of the detection frame 3. When the detection frame 3 and its related structures need to be repaired, it is only necessary to remove the screws between the first slide rail 10 and the detection platform 1 to perform modular overall repair and replacement of the detection frame 3 and its related structures.

[0029] Please see Figures 1-3 A second positioning component is provided between the bottom side of the detection frame 3 and the corresponding top side of the detection platform 1. The second positioning component includes a first L-shaped positioning plate 6 and a top pressure plate 7. The top of the first L-shaped positioning plate 6 is fixed to the corresponding side surface of the bottom of the detection frame 3. The middle part of the top pressure plate 7 is snapped into the side structure of the top of the detection platform 1. A folding spring sheet 9 is installed between the bottom surface of the top pressure plate 7 and the top side surface of the detection platform 1. When the folding spring sheet 9 is not under pressure, it pulls the top of the top pressure plate 7 to fit and connect with the bottom surface of the first L-shaped positioning plate 6. Several electric push rods 8 are arranged and installed on the side structure of the top of the detection platform 1. The output end of the electric push rod 8 can drive the bottom of the top pressure plate 7 and press the top of the top pressure plate 7 against the bottom of the first L-shaped positioning plate 6. The overall structure of the top pressure plate 7 is set as an I-shaped structure, and the top structure of the top pressure plate 7 is composed of damping material.

[0030] During use, considering the stability of the detection frame 3 before and after movement and adjustment, after the detection frame 3 is moved to a suitable position, multiple electric push rods 8 are activated. The output ends of the multiple electric push rods 8 press against the top plate 7, thereby pressing the top of the top plate 7 against the bottom of the first L-shaped positioning plate 6 to limit the displacement of the detection frame 3 and ensure the stability of the detection frame 3 during continuous use.
