[0002] Environmental simulation devices for new energy battery safety testing are key equipment to ensure the safety and reliability of batteries in practical applications. Their core function is to simulate the performance of batteries under various complex, extreme, or special environmental conditions. By monitoring changes in battery status and potential risks, they provide scientific basis for battery design optimization, standard setting, and safety certification. Factors such as temperature, humidity, and air pressure in the natural environment directly affect battery performance and safety. Environmental simulation devices can accurately reproduce these extreme conditions and test the battery's tolerance limits.

[0003] Existing environmental simulation devices for safety testing of new energy batteries can only spray water at a fixed angle during humidity simulation, which is inconvenient for spraying water stains on new energy batteries from multiple angles and can easily affect the testing results. Therefore, an environmental simulation device for safety testing of new energy batteries is provided. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses an environmental simulation device for safety testing of new energy batteries. (Refer to...) Figure 1 and Figure 5 An environmental simulation device for safety testing of new energy batteries includes a testing box 1, a clamping assembly 4 fixedly connected inside the testing box 1, and an adjustment assembly 3 fixedly connected to the inner wall of the testing box 1.

[0025] The adjustment assembly 3 includes two sets of gears 31. Both sides of the gears 31 are meshed with racks 33. A first motor 34 is provided on one side of the gears 31. A rotating shaft 35 is fixedly connected to the other side of the gears 31. An adjustment shaft 351 is fixedly connected to one end of the rotating shaft 35. One end of the adjustment shaft 351 passes through a limiting disk 36. The limiting disk 36 is fixedly connected to one side of the gears 31. A rotating disk 37 is fixedly connected to one end of the adjustment shaft 351. One side of the rotating disk 37 is slidably connected to the surface of the limiting disk 36. A nozzle 38 is fixedly connected to the other side of the rotating disk 37.

[0026] If nozzle 38 sprays liquids such as water, electrolyte, or salt spray, it can simulate the battery's condition in humid, rainy, electrolyte leaking, or coastal high-salt-fog environments, testing the battery casing's sealing and corrosion resistance, and whether liquid infiltration causes short circuits, abnormal positive and negative electrode reactions, or other safety issues. If it sprays high-temperature gases, low-temperature gases, inert gases (such as nitrogen), or corrosive gases (such as sulfur dioxide), it can simulate extreme temperatures, oxygen deficiency, and chemical pollution environments, evaluating the battery's performance stability under sudden temperature changes and gas corrosion (such as whether bulging, electrode oxidation, or thermal runaway occurs). Taking water spraying from nozzle 38 as an example, the first motor 34 drives gear 31 to rotate. During rotation, the nozzle 38 can move horizontally along the inner wall of the detection box 1, thereby ensuring that the nozzle 38 can be aimed at different parts of the battery (such as electrodes, casing, heat dissipation holes) to simulate local environmental changes such as water in a certain area of ​​the battery or local high temperature. During the rotation of the gear 31, the rotating shaft 35 and the adjusting shaft 351 can be rotated by the cloth. The rotation of the rotating shaft 35 and the adjusting shaft 351 can drive the rotating disk 37 to rotate. The limiting disk 36 can limit the rotation range of the rotating disk 37 to ensure stability and allow the spray angle of the nozzle 38 to be flexibly adjusted to simulate environmental impacts from different directions, such as rainwater slanting down and gas intruding from the side.

[0027] Reference Figure 1 and Figure 5 A fixing rod 32 is fixedly connected to one side of the rack 33. One end of the fixing rod 32 is fixedly connected to the inner wall of the detection box 1. The fixing rod 32 firmly fixes the rack 33 to the inner wall of the detection box 1, which can prevent the rack 33 from shifting, shaking or tilting when the gear 31 rotates.

[0028] Reference Figure 1 and Figure 5A water pump 21 is fixedly connected to the top of the detection box 1. The input end of the water pump 21 is connected to a water tank 22, and the output end of the water pump 21 is connected to a water pipe 26. One end of the water pipe 26 is connected to the surface of the nozzle 38. The water tank 22 serves as a liquid storage component, which can pre-store the liquid required for detection and provide raw material reserves for the entire system. The water pump 21 serves as a power source, drawing liquid from the water tank 22 through the input end and then pressurizing and delivering the liquid to the nozzle 38 through the water pipe 26 at the output end, ensuring that the nozzle 38 can continuously spray liquid and avoiding detection interruption due to insufficient liquid.

[0029] Reference Figure 1 and Figure 5 An inclined plate 27 is fixedly connected inside the detection box 1. A storage tank 24 is fixedly connected to one side of the inclined plate 27. A micro pump 25 is fixedly connected to the inner wall of the storage tank 24. The output end of the micro pump 25 is connected to a delivery pipe 23. One end of the delivery pipe 23 is connected to the inside of the water tank 22. By installing the inclined plate 27 at an angle inside the detection box 1, its angle design can guide the liquid that is not absorbed by the battery after being sprayed by the nozzle 38 to flow along the inclined surface and finally converge into the storage tank 24 on the lower side. The micro pump 25 is installed inside the storage tank 24. Its core function is to transport the recovered liquid back to the storage tank 24 through the delivery pipe 23 to realize the recycling of the liquid.

[0030] Reference Figure 1 and Figure 5 The clamping assembly 4 includes two sets of limiting boxes 41, which are fixedly connected to the inner wall of the detection box 1. One set of limiting boxes 41 contains a lead screw 42, and the other set of limiting boxes 41 contains a limiting slide rod 48. A slider 43 passes through one end of the lead screw 42 and the limiting slide rod 48. A threaded rod 45 passes through the top of the slider 43. A clamping plate 44 is fixedly connected to one end of the threaded rod 45, and a handle 46 is fixedly connected to the other end of the threaded rod 45. A second motor 47 is fixedly connected to one end of the lead screw 42. The two sets of limiting boxes 41 are respectively used to limit the lead screw 42 and the limiting slide rod 48. Rod 48 provides installation space and protection. The second motor 47 provides rotational power to the lead screw 42. When the lead screw 42 rotates, it drives the slider 43 connected to it to move along the axis of the lead screw 42 through threaded transmission. The limit rod 48 is used to ensure that the slider 43 and the battery above it remain parallel during the movement to prevent the battery from tilting. The threaded rod 45 at the top of the slider 43 adjusts the position of the clamping plate 44 by rotation. When the handle 46 is turned, the threaded rod 45 moves in and out along the threaded hole of the slider 43, driving the clamping plate 44 to move closer to or away from the battery. It can clamp batteries of different sizes to ensure that the battery does not shift during the testing process.

[0031] Reference Figure 1 and Figure 5Two sets of telescopic shafts 49 are fixedly connected to one side of the clamping plate 44. One end of the two sets of telescopic shafts 49 is fixedly connected to one side of the slider 43. When the handle 46 is rotated to adjust the position of the clamping plate 44 through the threaded rod 45, the telescopic shafts 49 will extend and retract synchronously with the clamping plate 44, forcing the clamping plate 44 to move only in the horizontal direction, avoiding the clamping plate 44 from tilting due to the unilateral force of the threaded rod 45, and avoiding uneven force on the battery due to the clamping angle deviation.

[0032] Reference Figure 1 and Figure 5 The test chamber 1 has a sealing door 102 hinged to one end, and observation windows 101 fixedly connected to both ends. The sealing door 102 is connected to the test chamber 1 by hinges. When closed, it can form a sealed space to prevent the simulated environment inside the test chamber 1 from leaking to the outside. At the same time, it avoids the external environment from interfering with the test conditions inside the chamber, ensuring the accuracy and stability of the environmental simulation. The observation window 101 is usually made of transparent high-temperature resistant or corrosion-resistant material. The operator can directly observe the status of the battery inside the chamber and the operation of the environmental simulation device through the observation window 101. The test progress can be monitored without opening the sealing door 102, avoiding damage to the sealed environment inside the chamber due to opening the door.

[0033] Working principle: When testing a new energy battery, the battery is placed on the surface of the slider 43. Turning the handle 46 causes the threaded rod 45 to move forward and backward along the threaded hole of the slider 43, moving the clamping plate 44 closer to or further away from the battery. This allows for clamping batteries of different sizes, ensuring the battery does not shift during testing. The second motor 47 provides rotational power to the lead screw 42. As the lead screw 42 rotates, it drives the connected slider 43 to move axially along the lead screw 42 via threaded transmission. A limiting slide rod 48 ensures that the slider 43 and the battery above it remain stationary during movement. Maintaining parallelism, the water tank 22, as a liquid storage component, can pre-store the liquid required for testing, providing raw material reserves for the entire system. The water pump 21, as a power source, draws liquid from the water tank 22 through its input end and then pressurizes and delivers the liquid to the nozzle 38 through the water pipe 26 at its output end, ensuring that the nozzle 38 can continuously spray liquid and preventing detection interruptions due to insufficient liquid. The inclined plate 27 is installed at an angle inside the detection box 1; its angle design guides any liquid not absorbed by the battery after being sprayed by the nozzle 38 to flow along the inclined surface, eventually converging into the storage tank 24 on the lower side. (Miniature...) Pump 25 is installed inside storage tank 24. Its core function is to recycle the recovered liquid back into storage tank 24 through conveying pipe 23, thus achieving liquid recycling. First motor 34 drives gear 31 to rotate. During the rotation of gear 31, it can move along rack 33, thereby driving nozzle 38 to move horizontally along the inner wall of detection box 1. This ensures that nozzle 38 can be aimed at different parts of the battery (such as electrodes, casing, heat dissipation holes), simulating local environmental changes such as water in a certain area of ​​the battery or local high temperature. The rotation of gear 31 also synchronously drives... The rotating shaft 35 and the adjusting shaft 351 rotate, allowing the rotating disk 37 to slide 360 ​​degrees along the surface of the limiting disk 36. The limiting disk 36 restricts the rotation range of the rotating disk 37 to ensure stability. Since the nozzle 38 and the rotating disk 37 are fixed together, the rotating disk 37 can simultaneously drive the nozzle 38 to slide while sliding on the surface of the limiting disk 36, thereby changing the spray angle of the nozzle 38 to simulate environmental impacts from different directions, such as rainwater flowing obliquely or gas intruding from the side.
