[0024] Please see Figure 1-4 This utility model provides a technical solution: a pressure resistance testing device for producing automotive power batteries, comprising:

[0025] The detection chamber 1 is divided into a liquid storage chamber 2 and a detection chamber 11 by a partition.

[0026] A lifting mechanism, located inside the testing chamber 1, includes multiple lifting cylinders 3 and a lifting platform 12. Multiple liquid storage chambers 2 are fixedly connected to the four corners of the testing chamber 1. The lifting platform 12 is slidably connected to the testing chamber 11 and fixedly connected to the top of the multiple lifting cylinders 3.

[0027] The testing mechanism is located on the lifting platform 12 and is used for battery pressure testing. The testing mechanism includes a synchronous control component, multiple sets of reset components and multiple pressing heads 8. The synchronous control component is located inside the lifting platform 12, and the multiple sets of reset components are all located inside the lifting platform 12. Each pressing head 8 is located on each set of reset components, and the multiple pressing heads 8 are all connected to the synchronous control component.

[0028] In this implementation scheme: the liquid storage chamber 2 and the detection chamber 11 are separated to avoid mutual interference during the detection process. The liquid storage chamber 2 is equipped with multiple partition covers to separate the lifting cylinder 3 from the liquid storage chamber 2, thus avoiding affecting the use of the lifting cylinder 3. The models of the multiple lifting cylinders 3 can be selected from those already available on the market as needed, which will not be elaborated here. The lifting platform 12 is adjusted in height by controlling the multiple lifting cylinders 3, thereby detecting the pressure resistance of the battery at different heights. The shape and length of the multiple pressing heads 8 can be selected accordingly as needed to improve the detection effect. The multiple pressing heads 8 cooperate with the lifting mechanism to adapt to the use of different batteries. The liquid storage chamber 2 contains liquid nitrogen to control the spread of heat. A fire extinguisher is also provided outside the detection box 1 for fire extinguishing.

[0029] Specifically, the synchronous control component includes a drive assembly, multiple L-links 9 and multiple straight links 13. The multiple L-links 9 are rotatably connected to the detection box 1, and the two ends of each straight link 13 are rotatably connected to each pair of L-links 9. The drive assembly is located inside the lifting platform 12.

[0030] In this embodiment, multiple L-links 9 and multiple straight links 13 work together to press multiple pressing heads 8 by moving the straight links 13, thus completing the use.

[0031] Specifically, the drive assembly includes a positioning cylinder 14 and a docking rod 18. The positioning cylinder 14 is rotatably connected to the lifting platform 12, and the docking rod 18 is rotatably connected to the output end of the positioning cylinder 14. The docking rod 18 is fixedly connected to one of the straight connecting rods 13.

[0032] In this embodiment, the model of the control cylinder 14 can be selected from those available on the market as needed, which will not be elaborated here. The control cylinder 14 drives the docking rod 18, causing one of the straight connecting rods 13 to move, and cooperates with multiple L connecting rods 9 to complete the synchronous movement of multiple straight connecting rods 13.

[0033] Specifically, each set of reset components includes a mounting base 10, a slide groove 16, a reset spring 15, and a docking slide plate 17. The mounting base 10 is installed inside the lifting platform 12, the slide groove 16 is opened on the mounting base 10, the reset spring 15 is fixedly connected to the mounting base 10, and the docking slide plate 17 is fixedly connected to the pressing head 8, and the docking slide plate 17 is slidably connected in the slide groove 16.

[0034] In this embodiment: the mounting base 10 is detachably installed in the corresponding position inside the lifting platform 12 to realize the pressure resistance test of different positions of the battery and facilitate the replacement of the pressing head 8. The docking slide plate 17 is installed in the slide groove 16 to restrict the movement path of the pressing head 8. At the same time, the position of the pressing head 8 is controlled by the reset spring 15 to ensure its use.

[0035] Specifically, it also includes a processing mechanism, which is located inside the testing box 1, for processing after battery testing. The processing mechanism includes an output pump 4, a water pipe 5, and multiple nozzles 6. The output pump 4 is fixedly connected to the liquid storage chamber 2 and is installed on the testing box 1. The output pump 4 extends into the testing chamber 11. The multiple nozzles 6 are all equidistantly connected to the water pipe 5.

[0036] In this embodiment, the model of the output pump 4 can be selected from those available on the market as needed, which will not be elaborated here. The output pump 4 sprays the liquid in the storage chamber 2 through the water pipe 5 and the nozzle 6 to cool the battery.

[0037] Specifically, the top of the testing box 1 is equipped with an upper cover 7.

[0038] In this embodiment, the upper cover 7 seals the detection box 1 to avoid affecting the external environment.

[0039] In use, select the corresponding pressing head 8 according to the size of the battery being tested. Place the battery in the center of the testing chamber 11. The lifting cylinder 3 controls the height of the lifting platform 12 to position the pressing head 8 in the testing position. After completion, the control cylinder 14 controls one of the straight connecting rods 13 to rotate through the docking rod 18. At the same time, multiple straight connecting rods 13 move synchronously through multiple L-connecting rods 9, squeezing the corresponding pressing head 8, causing the pressing head 8 to squeeze the battery and perform a pressure test on the battery. After the test is completed, the control cylinder 14 retracts, causing the straight connecting rod 13 to reset. At the same time, the pressing head 8 is reset due to the elastic force of the reset spring 15 and detaches from the battery. In case of battery fire, the fire is extinguished by an externally installed fire extinguisher. At the same time, the output pump 4 controls the liquid in the liquid storage chamber 2 to enter the water pipe 5 and spray it out through the nozzle 6 to quickly cool the battery.

[0040] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
