Description

Technical Field

[0001] This utility model relates to the field of battery pack testing technology, specifically a positioning device for battery pack testing. Background Technology

[0002] A battery pack consists of multiple battery modules, forming a single unit for storing and providing electrical energy. During the battery pack's production process, various tests must be conducted to ensure its performance stability, such as capacity testing, charging efficiency testing, and airtightness testing. In these tests, the primary function of the test positioning device is to clamp and secure the battery pack, thereby improving its stability during the testing process.

[0003] Existing clamping and positioning devices typically place the battery pack on a worktable and then clamp it by driving a clamping plate to contact the outer wall of the battery pack. However, traditional devices only position the battery pack by clamping its side walls. During testing, if the battery pack is subjected to external forces, it is prone to vertical displacement, thus reducing the stability of the battery pack clamping and positioning. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a positioning device for battery pack testing, which aims to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A positioning device for testing a battery pack includes a base frame, a plurality of clamping components are movably connected to the surface of the base frame, and a support frame is provided on the surface of the clamping components;

[0007] A lead screw is rotatably mounted inside the support frame, and a connecting plate is threaded onto the surface of the lead screw. The connecting plate is slidably connected to the clamping assembly, and a ramp is provided on the surface of the connecting plate, with the ramp facing the center area of ​​the base frame.

[0008] Furthermore, a rolling bearing is installed inside the support frame, and one end of the lead screw is installed inside the rolling bearing.

[0009] Furthermore, a torsion handle is installed at the end of the lead screw away from the rolling bearing.

[0010] Furthermore, the clamping assembly includes a support block, which is mounted on the surface of the base frame. A drive cylinder is mounted on the side of the support block, and a clamping frame is provided at one end of the drive cylinder. The support frame is disposed on the surface of the clamping frame.

[0011] Furthermore, the surface of the clamping frame is provided with a guide groove, and the connecting plate is slidably connected inside the guide groove.

[0012] Furthermore, the base frame has a sliding groove on its surface, and the clamping frame has a sliding frame installed on its surface. The clamping frame is slidably connected to the surface of the base frame through the cooperation of the sliding frame and the sliding groove.

[0013] Furthermore, a pressure sensor is mounted on the surface of the clamping frame.

[0014] Furthermore, the base frame has through holes on its surface, and a placement plate is installed inside the through holes. The surface of the placement plate has a perforated structure.

[0015] Furthermore, the base frame is equipped with several adjusting cylinders, and one end of each adjusting cylinder is connected to the placement plate.

[0016] The positioning device for battery pack testing provided by this utility model has the following beneficial effects:

[0017] This utility model's battery pack testing positioning device effectively improves the positioning accuracy of the battery pack through precise lead screw adjustment and inclined platform design. The lead screw rotates, driving the connecting plate to move smoothly, allowing the connecting plate to slide freely on the clamping assembly, thereby ensuring the battery pack is placed stably and accurately during testing. This structure prevents the battery pack from shifting during testing, reducing testing errors caused by inaccurate positioning.

[0018] The inclined platform further enhances positioning stability. With its inclined surface facing the center of the base frame, the platform applies clamping force evenly, ensuring balanced clamping of the battery pack in all directions. This effectively prevents deformation or movement of the battery pack due to uneven force, thereby improving the reliability of test results. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] like Figures 1-5 As shown in the figure, a positioning device for battery pack testing provided by this utility model includes a base frame 1. A plurality of clamping components 3 are movably connected to the surface of the base frame 1. The clamping components 3 are used to cooperate in operation to initially clamp and position the battery pack on the base frame 1. A support frame 4 is provided on the surface of the clamping components 3.

[0030] A lead screw 41 is rotatably mounted inside the support frame 4, and a rolling bearing is installed inside the support frame 4, with one end of the lead screw 41 installed inside the rolling bearing. A connecting plate 42 is threadedly connected to the surface of the lead screw 41, and the connecting plate 42 is slidably connected to the clamping assembly 3. A ramp 43 is provided on the surface of the connecting plate 42, and the ramp 43 faces the central area of ​​the base frame 1.

[0031] In one embodiment of this utility model, the clamping component 3 can employ four clamping methods to clamp and limit the battery pack, respectively positioned in the front, rear, left, and right directions of the battery pack. Each clamping component 3 can be adjusted independently.

[0032] During implementation, the battery pack is first placed on the base frame 1, ensuring its stability on the placement plate 2. After the battery pack is clamped onto the surface of the base frame 1 by four sets of clamping components 3, the lead screw 41 is rotated. The rotation of the lead screw 41 causes the connecting plate 42 to slide along the clamping components 3. As the connecting plate 42 slides, the inclined platform 43 gradually moves closer to the side of the battery pack, and the inclined surface of the inclined platform 43 contacts and applies pressure to the side wall of the battery pack. Continuing to rotate the lead screw 41, the inclined platform 43 will move closer to the top of the battery pack, ensuring that the battery pack is adequately limited in all directions.

[0033] The advantage of this design is that the movement of the connecting plate 42 can be precisely controlled by the lead screw 41, allowing the inclined platform 43 to apply pressure smoothly and evenly to the side walls and top of the battery pack, preventing displacement of the battery pack. The inclined surface design of the inclined platform 43 helps to achieve a stable clamping force, thereby improving the stability of the battery pack during testing and reducing testing errors that may be caused by uneven clamping. This precisely controlled clamping method effectively ensures the positional stability of the battery pack throughout the testing process, improving testing accuracy.

[0034] In this embodiment, a torsion handle is installed at the end of the lead screw 41 furthest from the rolling bearing. By manually rotating the handle, the operator can directly adjust the rotation of the lead screw, thereby driving the connecting plate 42 to move smoothly. This manual control method avoids complex electric drives or other mechanical transmissions, ensuring ease of operation and controllability.

[0035] The manual handle makes the adjustment process more intuitive, allowing operators to quickly and accurately control the application of clamping force, resulting in more stable battery pack positioning. This simplified manual operation not only improves efficiency but also reduces potential malfunctions or complexity from the electrical control system. Therefore, the manual handle design enhances the reliability and ease of operation of the device.

[0036] like Figures 1-4 As shown, in one embodiment of this utility model, the clamping assembly 3 includes a support block 33, which is mounted on the surface of the base frame 1. A drive cylinder 331 is mounted on the side of the support block 33, and a clamping frame 31 is provided at one end of the drive cylinder 331. A support frame 4 is disposed on the surface of the clamping frame 31. A guide groove 311 is formed on the surface of the clamping frame 31, and a connecting plate 42 is slidably connected to the inside of the guide groove 311. A sliding groove 11 is formed on the surface of the base frame 1, and a sliding frame 32 is mounted on the surface of the clamping frame 31. The clamping frame 31 is slidably connected to the surface of the base frame 1 through the cooperation of the sliding frame 32 and the sliding groove 11.

[0037] In this embodiment, the operation of the clamping assembly 3 begins when the battery pack is placed on the base frame 1. First, the support block 33 is fixedly installed on the surface of the base frame 1, and a drive cylinder 331 is installed on the side of the support block. One end of the drive cylinder 331 is connected to the clamping frame 31. The extension and retraction of the cylinder 331 causes the clamping frame 31 to move on the support block 33, gradually approaching the battery pack.

[0038] The base frame 1 has a sliding groove 11 on its surface, and a sliding frame 32 is mounted on the clamping frame 31. The sliding frame 32 cooperates with the sliding groove 11, allowing the clamping frame 31 to slide smoothly on the surface of the base frame 1. Through the cooperation of the sliding frame 32 and the sliding groove 11, the sliding of the clamping frame 31 is more stable, enabling precise clamping of the battery pack.

[0039] Throughout the process, the extension and retraction of the drive cylinder 331 drives the clamping frame 31 to move smoothly. Through the design of the slide groove 11 and the sliding frame 32, it is ensured that the clamping frame 31 can apply clamping force evenly and avoid deviation, thereby ensuring the stability of the battery pack during the test.

[0040] In this embodiment, a pressure sensor 312 is mounted on the surface of the clamping frame 31. Throughout the operation, the pressure sensor 312 monitors the pressure applied to the battery pack by the clamping frame 31 in real time. When the clamping frame 31 moves towards and clamps the battery pack under the action of the drive cylinder 331, the pressure sensor 312 detects the pressure value applied to the battery pack during the clamping process.

[0041] Activating the pressure sensor 312 enables precise control of the clamping force, ensuring that the clamping frame 31 does not over-clamp the battery pack, causing deformation of the outer wall, and also preventing the battery pack from loosening due to insufficient clamping force. The pressure sensor 312 feeds real-time pressure data back to the control system, thereby achieving dynamic adjustment of the clamping force. In this way, during the clamping process, the operator can monitor the clamping status of the battery pack in real time and adjust the clamping force based on the feedback information, ensuring the stability and accurate positioning of the battery pack during testing.

[0042] This design effectively improves the reliability and accuracy of the battery pack positioning device, avoiding the impact of improper clamping on test results.

[0043] like Figure 2 , Figure 6 and Figure 7 As shown, in one embodiment of this utility model, the surface of the base frame 1 has a through hole, and a placement plate 2 is disposed inside the through hole. The surface of the placement plate 2 has a perforated structure. This design has important applications.

[0044] First, the through-hole design allows the placement plate 2 to be stably mounted on the base frame 1, and also allows the placement plate 2 to move up and down inside the base frame 1. The through-hole design not only provides structural support for the installation of the placement plate, but also allows the placement plate 2 to be adjusted as needed, thus accommodating the placement of battery packs of different sizes and types.

[0045] The perforated structure on the surface of placement plate 2 provides better ventilation and heat dissipation, especially during battery pack testing, where the battery pack may generate heat. The perforated structure facilitates airflow, reduces temperature, and prevents the battery pack from overheating, which could affect testing accuracy or damage the battery pack.

[0046] Furthermore, the perforated structure reduces the weight of the placement plate 2, minimizing unnecessary burden and ensuring the stability and reliability of the device. Overall, the design of the through-hole and perforated structure makes the positioning device more efficient and stable, and can meet various requirements during battery pack testing.

[0047] In this embodiment, several adjusting cylinders 21 are installed inside the base frame 1, and one end of each adjusting cylinder 21 is connected to the placement plate 2. The main function of the adjusting cylinders 21 is to control the lifting and lowering of the placement plate 2, ensuring that the battery pack can be accurately placed and positioned. During the test, the adjusting cylinders 21 adjust the height of the placement plate 2 through extension and retraction, thereby securing the battery pack on the base frame 1. When the adjusting cylinders 21 extend, the placement plate 2 rises, ensuring stable contact between the battery pack and the base frame 1; when the adjusting cylinders 21 retract, the placement plate 2 sinks, allowing the battery pack to be accurately positioned before testing.

[0048] Furthermore, the use of the adjusting cylinder 21 can help adapt to battery packs of different sizes, ensuring that the placement plate 2 can be flexibly adjusted regardless of changes in battery pack size, thereby ensuring the stability of the battery pack during each test. The precise control of the adjusting cylinder 21 effectively improves positioning accuracy during testing, avoiding battery pack instability caused by unsuitable height, and thus ensuring the accuracy of test results.

[0049] Overall, the regulating cylinder 21 provides the necessary power and precision, optimizes the battery pack placement process, and improves the flexibility and reliability of the equipment.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
