[0034] Example

[0035] Please see Figure 1-8 A lithium battery safety performance testing device includes a support base 100, a first support frame 110 fixedly mounted on the top of the support base 100, a battery safety performance testing mechanism 200 installed inside the first support frame 110, a second support frame 120 fixedly mounted on the top of the first support frame 110, a drive mechanism 300 for driving the lifting and lowering movement of the battery safety performance testing mechanism 200 installed inside the second support frame 120, a control panel 400 mounted on the front of the second support frame 120, a protective cover 121 covering the top of the second support frame 120, protective plates 111 fixedly mounted on both sides of the first support frame 110, a perforated plate 112 mounted on the back of the first support frame 110, and a fire extinguishing mechanism 500 mounted on the back of the perforated plate 112.

[0036] Specifically, during lithium battery safety performance testing, the battery to be tested is placed in the battery safety performance testing mechanism 200 within the first support frame 110. During the testing process, the drive mechanism 300 within the second support frame 120 drives the battery safety performance testing mechanism 200 to perform lifting and lowering movements to achieve operations such as pressurizing the battery. The operator sets the testing parameters and controls the operation of the equipment through the control panel 400 on the front of the second support frame 120. The protective cover 121 on the top of the second support frame 120 and the protective plates 111 on both sides of the first support frame 110 can prevent foreign objects from entering or hazardous substances from leaking out during the testing process. In case of emergency such as battery fire, the fire extinguishing mechanism 500 behind the perforated plate 112 on the back of the first support frame 110 can quickly respond to extinguish the fire.

[0037] In this embodiment, two placement boxes 113 are also fixedly connected to the top of the support base 100. One placement box 113 is used to place the battery to be tested, and the other placement box 113 is used to place the battery after testing.

[0038] Specifically, before testing, the operator neatly places the battery to be tested into one of the placement boxes 113 on top of the support base 100 for easy access for testing. After testing, the tested battery is removed from the battery safety performance testing mechanism 200 and placed into another placement box 113, thus achieving classified storage of the battery to be tested and the tested battery to avoid confusion, while maintaining the cleanliness and orderliness of the testing area and improving the smoothness of the testing process.

[0039] In this embodiment: the battery safety performance testing mechanism 200 includes two fixed seats 210 located inside the first support frame 110 and fixedly installed on the top of the support base 100. Each fixed seat 210 has an electric heating plate 220 fixedly installed on its top. The surface of the electric heating plate 220 has multiple insertion holes 221.

[0040] Specifically, during testing, the two fixed seats 210 in the battery safety performance testing mechanism 200 are securely installed on the top of the support seat 100, providing stable support for the electric heating plate 220 above. According to the testing requirements, the electric heating plate 220 can be heated to a set temperature to simulate a high-temperature environment to test the battery's safety performance. Multiple insertion holes 221 on the surface are used to cooperate with the insertion positioning pins 231 at the bottom of the battery fixture 230 to ensure that the battery fixture 230 can be accurately installed on the electric heating plate 220, ensuring the stability of the testing process.

[0041] In this embodiment: a battery fixture 230 is provided on the top of the electric heating plate 220, and a plurality of plug-in positioning pins 231 are fixedly connected to the bottom of the battery fixture 230. The plug-in positioning pins 231 are inserted into the plug-in holes 221 and are used for convenient assembly of the battery fixture 230 and the electric heating plate 220. A plurality of charging contacts 232 are provided on the inner side of the battery fixture 230. The charging contacts 232 are in close contact with the battery contacts placed inside the battery fixture 230. The charging contacts 232 are also connected to the charging power supply outside the first support frame 110 through wires.

[0042] Specifically, when installing the battery, the insertion positioning pin 231 at the bottom of the battery fixture 230 is aligned with the insertion hole 221 of the electric heating plate 220 and inserted to complete the rapid assembly of the battery fixture 230 and the electric heating plate 220. Then, the battery to be tested is placed in the battery fixture 230, and the charging contact 232 on the inside of the battery fixture 230 is in close contact with the battery contact. The external charging power supply connected by the wire supplies power to the battery, simulating the battery charging and discharging scenario, thereby testing the safety performance of the battery during the charging and discharging process.

[0043] In this embodiment: a pressing block 240 is provided on the top of the battery fixture 230, and the pressing block 240 is connected to the pressing fixture 250 by bolts. The pressing fixture 250 is connected to the drive mechanism 300.

[0044] Specifically, when a battery needs to be pressurized for testing, the drive mechanism 300 drives the lower pressure fixture 250 to descend, and the lower pressure block 240, which is connected to the lower pressure fixture 250 by bolts, moves downwards until the lower pressure block 240 contacts the battery in the battery fixture 230 and applies pressure. The bolt connection method facilitates the disassembly and replacement of the lower pressure block 240. According to the testing requirements of different battery models, the appropriate lower pressure block 240 can be replaced to ensure the accuracy of the pressurization test.

[0045] In this embodiment: a plurality of pressure sensors 241 are mounted in a rectangular array on the bottom surface of the pressure block 240, and a plurality of temperature sensors 242 are also mounted on the bottom surface of the pressure block 240.

[0046] Specifically, during the pressure testing of the battery, the pressure sensor 241 of the rectangular array at the bottom of the pressure block 240 contacts the battery surface, monitors and feeds back the pressure value applied to the battery in real time, and ensures that the pressure meets the test setting requirements. At the same time, the temperature sensor 242 detects the temperature change of the battery surface in real time and transmits the temperature data to the control system. When the pressure or temperature exceeds the safe range, the equipment can issue an alarm in time and take corresponding measures to ensure the safety of the test.

[0047] In this embodiment: the drive mechanism 300 includes a mounting plate 310 fixedly installed inside the bottom of the second support frame 120. Two servo electric telescopic rods 320 are installed on the top of the mounting plate 310. The telescopic ends of the servo electric telescopic rods 320 are fixedly connected to the top of the pressing fixture 250. Multiple guide telescopic rods 330 are fixedly installed on the bottom of the mounting plate 310. The bottom ends of the guide telescopic rods 330 are fixedly connected to the top of the pressing fixture 250.

[0048] Specifically, when the drive mechanism 300 is working, the mounting plate 310 is fixed inside the bottom of the second support frame 120, providing a stable mounting base for the servo electric telescopic rod 320. According to the detection command, the telescopic end of the servo electric telescopic rod 320 drives the pressure fixture 250 to perform precise lifting and lowering, realizing the pressurization or depressurization operation of the battery. The multiple guide telescopic rods 330 at the bottom of the mounting plate 310 are connected to the pressure fixture 250, playing a guiding role during the lifting and lowering process, preventing the pressure fixture 250 from deviating, and ensuring the accuracy of the pressurization direction.

[0049] In this embodiment: a camera gimbal 130 is fixedly installed on the top of the support base 100 between the two battery fixtures 230. A camera mount 131 is installed on the top of the camera gimbal 130. Two CCD cameras 132 are installed inside the camera mount 131, each facing the two battery fixtures 230. Multiple columnar lights 140 are installed on the inner side of the first support frame 110.

[0050] Specifically, during the testing process, the two CCD cameras 132 inside the camera mount 131 are respectively aimed at the batteries in the two battery fixtures 230 to capture real-time changes in the battery's state during the testing process, such as whether bulging or smoking occurs. The columnar lighting lamp 140 inside the first support frame 110 provides sufficient light to ensure that the CCD camera 132 can clearly capture the battery's state, making it easier for operators to judge the battery's safety performance through the images.

[0051] In this embodiment: the control panel 400 includes a mounting housing 410 fixedly installed on the front of the second support frame 120. The main control circuit board 440 is integrated inside the mounting housing 410. A touch screen display 420 that is bidirectionally electrically connected to the main control circuit board 440 is embedded on the front of the mounting housing 410. The surface of the mounting housing 410 is also provided with a plurality of function buttons 430 that are electrically connected to the main control circuit board 440. The mounting housing 410 is provided with an audible and visual alarm device 450 that is electrically connected to the main control circuit board 440. The main control circuit board 440 is electrically connected to the electric heating plate 220, pressure sensor 241, temperature sensor 242, current sensor and voltage sensor in the charging contact 232 circuit of the battery safety performance testing mechanism 200, the servo electric telescopic rod 320, CCD camera 132, column lighting lamp 140 in the drive mechanism 300, and electromagnetic control valve 530 in the fire extinguishing mechanism 500.

[0052] Specifically, the operator can view the equipment operating parameters and battery test data through the touch screen 420 embedded in the front of the mounting housing 410 of the control panel 400. The operator can also set the test parameters through the function buttons 430 on the surface. The main control circuit board 440 inside the mounting housing 410 serves as the control core, receiving signals transmitted from the pressure sensor 241, temperature sensor 242, etc., and sending control commands to the electric heating plate 220, servo electric telescopic rod 320, etc. When the test data is abnormal, the audible and visual alarm device 450 will sound an alarm, and the main control circuit board 440 can control the electromagnetic control valve 530 of the fire extinguishing mechanism 500 to open, so as to deal with dangerous situations in a timely manner.

[0053] In this embodiment: the fire extinguishing mechanism 500 includes an outer cover 510 fixedly installed on the back of the perforated plate 112. A connecting pipe head 520 is fixedly connected to the back of the outer cover 510. A high-pressure water source is connected to the connecting pipe head 520. An electromagnetic control valve 530 is also installed at the connection between the connecting pipe head 520 and the high-pressure water source pipe.

[0054] Specifically, when an emergency such as a battery fire occurs during the testing process, the outer cover 510 of the fire extinguishing mechanism 500 protects the internal structure, controls the opening of the electromagnetic control valve 530, and delivers an external high-pressure water source to the outer cover 510 through the connecting pipe head 520. The high-pressure water flows through the holes of the perforated plate 112 and sprays into the interior of the first support frame 110, quickly extinguishing the battery flame, preventing the fire from spreading, and ensuring the safety of the equipment and operators.

[0055] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations.
