[0002] Batteries are high-density energy storage devices with a wide range of applications. Once an accident occurs, it may affect the use of the equipment at the least, or even cause explosion and combustion at the worst. At present, many electrical products are equipped with batteries as power sources or as backup power sources. If the electrical products are used in harsh environments, such as collisions, extrusions, impacts, and sharp object punctures, the reliability requirements of the batteries in this use environment are high to prevent the batteries from exploding or breaking and leaking under extrusion or impact, thereby causing damage to people or objects. Therefore, the batteries need to be subjected to puncture tests when they are produced and leave the factory.

[0003] The existing battery puncture test equipment is mainly composed of a protective cabinet, a placement table, a positioning member, a cylinder and a puncture needle. Generally, the battery is placed on the top of the placement table, and the battery is limited by the positioning member to prevent the battery from shifting during the test and affecting the test results. The puncture needle is driven by the cylinder to move toward the battery and pass through the battery. The existing positioning member is mainly composed of a threaded rod and two clamps. By rotating the threaded rod, the two clamps move toward each other, thereby limiting the battery. Such operation is relatively complicated, not convenient, not conducive to repeated operations, and reduces processing efficiency.

[0004] Therefore, it is necessary to provide a new battery puncture test equipment to solve the above technical problems. Utility Model Content

[0008] Preferably, the driving member is a hydraulic cylinder, the bottom of the hydraulic cylinder is fixedly connected to the bottom of the placement component, and the output end of the hydraulic cylinder is fixedly connected to the bottom of the fixed block.

[0009] Preferably, the fixing assembly comprises two connecting plates, one side of the bottom of the two connecting plates is fixedly connected to two sides of the fixing block respectively, and two ends of the mounting column are fixedly connected to one side adjacent to the two connecting plates respectively.

[0010] Preferably, the placement assembly includes a mounting plate, a limit member and a placement table, the mounting plate is fixed to the inside of the protective cabinet by a plurality of bolts, the bottom of the limit member is fixedly connected to the top of the mounting plate, the detection component is fixed to the top of the limit member, the bottom of the placement table is fixedly connected to the top of the mounting plate, and a plurality of telescopic blocks are provided on the top of the placement table.

[0011] Preferably, the limiting member includes a fixing plate and four supporting columns, one end of the four supporting columns are respectively fixedly connected to the top of the mounting plate, and one end of the four supporting columns away from the mounting plate respectively passes through the four corners of the fixing plate, and the supporting columns are fixedly connected to the fixing plate.

[0013] Compared with the related art, the battery puncture test equipment provided by the utility model has the following beneficial effects:

[0014] Through the precise control of the driving part, the fixed block is driven to move upward. Since the movable rod is movably connected to the mounting column, when the fixed block moves upward, the movable rod will rotate along the surface of the mounting column. As the fixed block moves upward, the end of the movable rod close to the extrusion rod will rotate downward. Since the movable rod and the extrusion rod are movably connected through two connecting rods and a supporting rod, when the end of the movable rod close to the extrusion rod moves downward, the bottom of the extrusion rod will fit better with the battery surface, thereby increasing the contact area with the battery surface. The above structure facilitates the positioning of the battery, thereby improving the processing efficiency to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS
