A testing device for battery pack production

Abstract

This utility model discloses a testing device for battery pack production, relating to the field of battery pack testing technology. It includes several horizontal plates, with several empty cylinders fixedly mounted on the surface of each plate. An impact assembly is installed inside each cylinder, comprising a spring assembly fixedly mounted on one side of the cylinder's interior. A movable block is elastically connected inside the cylinder via the spring assembly. One side of the movable block has a connecting shaft extending through the cylinder, and the other side of the movable block has an impact rod fixedly mounted. Through the attraction between opposite poles of a first and second magnetic block, when the first and second magnetic blocks are perpendicular, the connecting shaft, along with the movable block and the impact rod, contracts towards the inner cavity of the cylinder, compressing the spring assembly. When the first and second magnetic blocks are not perpendicular, the spring force causes the movable block, along with the impact rod, to rapidly impact the battery pack, avoiding deviations in test data caused by varying release forces during manual testing.

Description

Technical Field

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

[0002] The main function of a battery pack is to integrate multiple battery modules into a single unit. The battery modules are connected in parallel or series to increase the voltage, capacity, or power of the battery system. The battery pack is also responsible for providing other functions and features required by the battery system, such as electrical interfaces for connecting to external systems, a heat dissipation system for controlling temperature, a casing for protecting the battery, and other auxiliary equipment and components.

[0003] During the production process, battery packs typically undergo impact testing to detect whether bulging will occur during use. However, existing battery impact tests rely on manual striking, which can lead to measurement deviations due to varying striking force. To address these issues, a new testing device for battery pack production is proposed. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a testing device for battery pack production.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a testing device for battery pack production, comprising a testing platform, a U-shaped frame fixedly installed on one side of the top center position of the testing platform, a plurality of horizontal plates fixedly installed on one side of the interior of the U-shaped frame, a plurality of empty cylinders fixedly installed on the surface of the horizontal plates, and an impact assembly provided inside the empty cylinders; the impact assembly includes a spring assembly fixedly installed on one side of the interior of the empty cylinders, a movable block elastically connected to the interior of the empty cylinders through the spring assembly, a connecting shaft extending through the empty cylinders on one side of the movable block, an impact rod fixedly installed on the other side of the movable block, a movable plate slidably connected to the other side of the interior of the U-shaped frame, a plurality of first magnetic blocks fixedly installed on the side of the movable plate facing the empty cylinders, and a second magnetic block fixedly installed on the side of the connecting shaft.

[0006] Preferably, the first magnetic block and the second magnetic block are opposite poles that attract each other.

[0007] Preferably, a servo motor is provided inside the U-shaped frame, and a threaded rod is installed on the radial inner wall of the moving plate through internal and external thread engagement, and the output end of the servo motor is connected to the threaded rod for transmission.

[0008] Preferably, a frustum is fixedly installed at the center of the top of the testing platform, and a drive motor is provided at the center of the interior of the frustum. The output end of the drive motor is connected to a loading plate.

[0009] Preferably, the surface of the tray is symmetrically provided with sliding grooves, and threaded blocks are slidably connected inside the two sliding grooves. A lead screw is installed on the radial inner wall of the threaded block through internal and external thread engagement, and a fixing bracket is fixedly installed on the surface of the threaded block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] By using the impact assembly, the opposite poles of the first and second magnetic blocks attract each other. When the first and second magnetic blocks are perpendicular, the connecting shaft, along with the moving block and impact rod, contracts toward the inner cavity of the empty cylinder and squeezes the spring assembly. When the first and second magnetic blocks are not perpendicular, the spring force causes the moving block, along with the impact rod, to quickly impact the battery pack, thus avoiding deviations in test data caused by different release forces during manual testing.

[0018] 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.

[0019] Example: Figures 1-4 As shown, this utility model provides a testing device for battery pack production, including a testing platform 1. A U-shaped frame 7 is fixedly installed on one side of the top center position of the testing platform 1. Several horizontal plates 8 are fixedly installed on one side of the interior of the U-shaped frame 7. Several empty cylinders 9 are fixedly installed on the surface of the horizontal plates 8. An impact component is provided inside the empty cylinder 9. The impact component includes a spring assembly 901 fixedly installed on one side of the interior of the empty cylinder 9. A moving block 902 is elastically connected to the interior of the empty cylinder 9 through the spring assembly 901. As the moving block 902 slides toward the interior cavity of the empty cylinder 9, it compresses the spring assembly 901. A connecting shaft 904 is provided through the empty cylinder 9 on one side of the moving block 902. An impact rod 903 is fixedly installed on the other side of the moving block 902. Rod 903 moves synchronously with moving block 902. Moving plate 10 is slidably connected to the other side of U-shaped frame 7. Several first magnetic blocks 11 are fixedly installed on the side of moving plate 10 facing empty cylinder 9. Second magnetic blocks 905 are fixedly installed on one side of connecting shaft 904. First magnetic blocks 11 and second magnetic blocks 905 are opposite magnetic and attract each other. When first magnetic blocks 11 and second magnetic blocks 905 are in a perpendicular state, under the action of opposite magnetic attraction, connecting shaft 904, along with moving block 902 and impact rod 903, slides towards the inner cavity of empty cylinder 9 to store force. When first magnetic blocks 11 and second magnetic blocks 905 are not perpendicular, under the elastic force of spring assembly 901, moving block 902, along with impact rod 903, slides quickly towards battery pack and impacts it.

[0020] The U-shaped frame 7 is equipped with a servo motor inside. The radial inner wall of the moving plate 10 is fitted with a threaded rod 12 through internal and external thread engagement. The output end of the servo motor is connected to the threaded rod 12 for transmission.

[0021] By adopting the above technical solution, the output end of the servo motor drives the threaded rod 12 to rotate. During the rotation of the threaded rod 12, it interacts with the moving plate 10, thereby causing the moving plate 10 to move up or down inside the U-shaped frame 7.

[0022] A frustum 2 is fixedly installed at the center of the top of the testing table 1. A drive motor is located at the center of the frustum 2. The output end of the drive motor is connected to a loading plate 3. The surface of the loading plate 3 is symmetrically provided with sliding grooves 4. Threaded blocks are slidably connected inside the two sliding grooves 4. A lead screw 5 is installed on the radial inner wall of the threaded block through internal and external thread engagement. A fixing bracket 6 is fixedly installed on the surface of the threaded block.

[0023] By adopting the above technical solution, the battery pack is placed at the center of the surface of the carrier plate 3. The lead screw 5 rotates under the power drive built into the carrier plate 3, so that the two threaded blocks with the fixing frame 6 move toward the battery pack and clamp the battery pack. The drive motor drives the carrier plate 3 to rotate, thereby enabling impact detection on different sides of the battery pack.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
