The battery platform is movably located inside the puncture chamber and is connected to a movable lifting end. The bottom of the lifting drive unit is hinged to the test body, and the movable end of the lifting drive unit is hinged to the bottom of the battery platform.

The reaction after battery puncture occurs within the puncture chamber, reducing the impact on the power components in the power chamber and avoiding safety threats to the surrounding working environment.

[0010] By installing a lifting drive component in the power compartment, the battery platform is driven to move up and down in the puncture chamber to transport the battery to or away from the puncture working surface. By hinged between the bottom of the lifting drive component and the test body, and hinged between the movable end of the lifting drive component and the bottom of the battery platform, the support stability of the lifting drive component on the battery platform during the lifting movement can be improved.

[0024] To achieve the above technical solution, the observation netting can prevent large debris from posing a safety threat to the surrounding area, while the first observation glass serves as the first line of protection to prevent threats to the outside world during the reaction process. The second observation glass installed on the puncture chamber door serves as the second line of protection to further enhance the test unit's protection of the surrounding environment.

[0025] As described above, the power battery puncture and compression testing device of this utility model has the following beneficial effects: by arranging a puncture chamber and a power chamber vertically in the testing machine body, the two sets of chambers can achieve different functions, avoiding mutual interference during the puncture process. Furthermore, it is convenient to complete the puncture test in the puncture chamber during power battery puncture testing, improving the safety of the puncture action and facilitating the observation of the puncture situation. The reaction after battery puncture occurs in the puncture chamber, reducing the impact on the power components in the power chamber and avoiding safety threats to the surrounding working environment.

[0026] By installing a lifting drive component in the power compartment, the battery platform is driven to move up and down in the puncture chamber to transport the battery to or away from the puncture working surface.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] Please see Figures 1 to 7This utility model provides a power battery puncture and compression detection device, including a puncture chamber 2 and a power chamber 3 arranged vertically inside a test body 1. A lifting drive 5 is provided in the power chamber 3. A battery platform 4 is movably disposed in the puncture chamber 2 and connected to the movable end of the lifting drive 5.

The puncture head 6 is located at the top of the test body 1 along the movement trajectory of the battery platform 4.

[0038] By vertically arranging a puncture chamber 2 and a power chamber 3 within the test body 1, the two sets of chambers can achieve different functions, avoiding mutual interference during the puncture process. Furthermore, it facilitates the completion of the puncture test within the puncture chamber 2 during power battery puncture testing, improving the safety of the puncture action and facilitating the observation of the puncture situation. The reaction after battery puncture occurs within the puncture chamber 2, reducing the impact on the power components within the power chamber 3 and avoiding safety threats to the surrounding working environment.

[0039] By installing a lifting drive component 5 in the power compartment 3, the battery platform 4 is driven to move up and down in the puncture chamber 2 to transport the battery to or away from the puncture working surface. By hinged between the bottom of the lifting drive component 5 and the test body 1, and hinged between the movable end of the lifting drive component 5 and the bottom of the battery platform 4, the support stability of the lifting drive component 5 on the battery platform 4 during the lifting movement can be improved.

[0040] The battery platform 4 has a platform hinge base 7 at its bottom, and a downwardly protruding hinge lug 8 on the platform hinge base 7. The movable end of the lifting drive component 5 has a movable end hinge joint 9. The movable end hinge joint 9 and the hinge lug 8 are rotatably connected. By using the hinge base 10 at the bottom of the battery platform 4 and the downwardly protruding hinge lug 8 on the hinge base 10 to connect the movable end hinge joint 9 of the lifting drive component 5, the stability of the lifting and lowering movement of the battery platform 4 driven by the lifting drive component 5 can be improved.

[0041] A hinged base 10 is provided between the bottom of the lifting drive component 5 and the bottom of the power compartment 3. The bottom of the fixed end of the lifting drive component 5 is rotatably connected to the hinged base 10.

The second observation glass 17 installed on the door to the puncture chamber 2 serves as the second line of protection to further enhance the protection effect of the test body 1 on the surrounding environment.

[0047] This invention features a puncture chamber and a power chamber arranged vertically within the testing machine. These two chambers serve different functions, preventing interference between them during the puncture process. Furthermore, the puncture test is conveniently performed within the puncture chamber, improving safety and facilitating observation of the puncture. The battery's reaction after puncture occurs within the puncture chamber, minimizing impact on the power components within the power chamber and preventing safety threats to the surrounding working environment. A lifting drive unit within the power chamber moves the battery platform up and down within the puncture chamber, transporting the battery to or away from the puncture working surface. The lifting drive unit's bottom is hinged to the testing machine body, and its movable end is hinged to the bottom of the battery platform, enhancing the stability of the lifting drive unit's support for the battery platform during the lifting motion.
