[0002] With the continuous development of new energy technologies, new energy vehicles with lithium batteries as power energy storage carriers are developing rapidly and becoming a major trend of the times. Since the electrolyte in the lithium-ion batteries used in current new energy vehicles is a flammable and explosive material, when a new energy vehicle collides, causing damage to the lithium-ion battery or internal short circuit, sparks will be generated between the positive and negative electrodes, which will then ignite the electrolyte, leading to combustion and explosion. Therefore, comprehensive combustion and explosion performance experiments need to be carried out on new energy batteries during production.

[0003] The existing new energy battery combustion and explosion experiment instruments have poor safety effects during use and cannot provide comprehensive protection during the combustion test, resulting in the new energy battery splashing everywhere during combustion and explosion, which is likely to cause certain harm to the surrounding environment and workers. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a new energy battery combustion and explosion performance tester that can play a good protective role during the test.

A weighing device is fixedly installed inside the test bench, and a combustion heater is fixedly installed on the top of the weighing device. A protective structure is arranged on the test bench. The protective structure includes a fixed frame fixedly installed on the top of the test bench. A plurality of hydraulic rods are symmetrically installed on both sides of the fixed frame. First and second protective covers are symmetrically arranged on the top of the combustion heater.

Detailed implementation manners

[0021] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0022] As Figures 1 - 5 shown, a new energy battery combustion and explosion performance tester includes a test bench 1 and a display arranged on its front. A weighing device 2 is fixedly installed inside the test bench 1, and a combustion heater 3 is fixedly installed on the top of the weighing device 2. A protective structure 4 is arranged on the test bench 1. The protective structure 4 includes a fixing frame 5 fixedly installed on the top of the test bench 1. A plurality of hydraulic rods 6 are symmetrically installed on both sides of the fixing frame 5. A first protective cover 7 and a second protective cover 8 are symmetrically arranged on the top of the combustion heater 3. A plurality of fixing blocks 9 connected to the output ends of the hydraulic rods 6 are fixedly installed on both sides of the first protective cover 7 and the second protective cover 8. Through the setting of the protective structure 4, the burning new energy battery can be wrapped during the test. After placing the new energy battery to be tested on the combustion heater 3, a plurality of hydraulic rods 6 are simultaneously started to extend their output ends and drive the first protective cover 7 and the second protective cover 8 to move through the fixing blocks 9. When the first protective cover 7 and the second protective cover 8 are fitted, the battery can be wrapped inside, thereby playing a protective role during the test, avoiding the splashing of the new energy battery during combustion and explosion, and preventing harm to the surrounding environment and the staff.

[0023] A sealing strip 10 is fixedly installed on the upper part of the first protective cover 7, and a sealing groove 11 for cooperating with the sealing strip 10 is formed on the second protective cover 8; window frames 12 are fixedly installed on one side of the first protective cover 7 and the second protective cover 8, and viewing windows 13 are fixedly installed inside the window frames 12; fixing frames 14 are fixedly installed at both ends of the combustion heater 3, and filter meshes 15 are fixedly installed inside the fixing frames 14. After the first protective cover 7 and the second protective cover 8 are fitted together, the sealing strip 10 is inserted into the sealing groove 11. After the sealing strip 10 and the sealing groove 11 are combined, the sealing performance at the joint of the first protective cover 7 and the second protective cover 8 can be improved, thereby preventing smoke and dust from overflowing; the arrangement of the window frames 12 and the viewing windows 13 facilitates viewing the combustion state of the battery enclosed inside the first protective cover 7 and the second protective cover 8; the arrangement of the fixing frames 14 and the filter meshes 15 can play a role in protecting and filtering the air inlet of the combustion heater 3, preventing foreign objects from being sucked into the interior and causing damage to the combustion heater 3.

[0024] A fixing plate 16 is fixedly installed on the top of the fixing frame 5, a fan 17 is fixedly installed on the fixing plate 16, a hose 18 is installed between the fan 17 and the first protective cover 7 and the second protective cover 8, and a filter box 19 is arranged on the top of the fan 17; two support plates 20 are symmetrically installed on the fan 17, a spring 21 is fixedly installed on one side of the support plate 20, one end of the spring 21 is fixedly installed with a limiting rod 22, and a plurality of limiting blocks 23 are fixedly installed on both sides of the filter box 19. One end of the limiting rod 22 penetrates through the spring 21 and the limiting rod 22 and is engaged with the limiting block 23; two positioning rods 24 are symmetrically installed on the surface of the fan 17, and a plurality of positioning blocks 25 for cooperating with the positioning rods 24 are fixedly installed on the surface of the filter box 19. During the combustion process of the new energy battery, flue gas is generated. Starting the fan 17 can extract the flue gas inside the first protective cover 7 and the second protective cover 8 and transport it to the filter box 19 for filtration and then discharge. It can timely discharge the flue gas and avoid polluting the environment. At the same time, the fan 17 is connected to the first protective cover 7 and the second protective cover 8 by a flexible hose 18 with elasticity, which will not hinder the movement of the first protective cover 7 and the second protective cover 8; the filter box 19 and the fan 17 are fixedly connected by the engagement of the limiting rod 22 and the limiting block 23, which can not only prevent the filter box 19 from falling off the fan 17, but also, since the limiting rod 22 is supported by the spring 21, it can be pulled to one side, thus facilitating the disassembly and cleaning of the filter box 19; the arrangement of the positioning rods 24 and the positioning blocks 25 can play a role in positioning when installing the filter box 19, making the installation of the filter box 19 more convenient and avoiding deviation.

[0025] The working process of the new energy battery combustion and explosion performance tester provided in this embodiment is as follows:

[0026] Zero the weighing scale 2, and then place the new energy battery to be tested on the combustion heater 3. The value shown on the weighing scale 2 is the mass of the battery. At the same time, activate multiple hydraulic rods 6 so that their output ends extend and drive the first protective cover 7 and the second protective cover 8 to move through the fixing block 9. When the first protective cover 7 and the second protective cover 8 are in contact, they can wrap the battery inside. Activate the combustion heater 3 to test the combustion of the new energy battery, and the value of the weighing scale 2 can be observed in real time through the display screen on the front of the test bench 1.
