[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application; the terms "including" and "having" in the specification and claims of the present application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present application or the above-mentioned figures are used to distinguish different objects, rather than to describe a specific order; the terms "inside", "outside", "left", and "right" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0037] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] The embodiment of the present invention provides a new energy vehicle battery performance detection device, such as Figure 1-16 As shown, the new energy vehicle battery performance testing device includes: a box body 1 and a hydraulic cylinder 4 arranged in the box body 1 for testing the pressure resistance of the battery, and a pressure plate 5 arranged on the hydraulic cylinder 4; a placement box 3 arranged in the box body 1 for placing the battery, and the placement box 3 is arranged directly below the pressure plate 5; an arc light detection device 6 and a smoke detector 7 installed in the box body 1 for monitoring the battery detection status; a perfluorohexanone storage tank 8 arranged in the box body 1 for extinguishing the battery, and a drain pipe 9 arranged below the perfluorohexanone storage tank 8; an opening and closing mechanism arranged on the box body 1 for opening and closing the inlet and outlet of the box body 1.

[0039] In this embodiment, during the detection process, the hydraulic cylinder 4 drives the pressure plate 5 to apply pressure to the battery placed in the placement box 3 to test the pressure resistance of the battery. At the same time, the arc light detection device 6 is used to monitor whether the battery has an arc light generated when the battery is short-circuited during the detection process, and the smoke detector 7 is used to detect whether the battery generates smoke due to overheating and other reasons and smoke caused by fire;

[0040] Once the arc light detection device 6 or the smoke detector 7 detects an abnormal situation, such as a battery short circuit or fire, the perfluorohexanone storage tank 8 will quickly release the perfluorohexanone fire extinguishing agent through the drain pipe 9 to extinguish the battery. The opening and closing mechanism is used to open and close the inlet and outlet of the box before and after the detection to ensure the safety and closedness of the detection process. The fire extinguishing system composed of the arc light detection device 6 and the smoke detector 7, as well as the perfluorohexanone storage tank 8 and the drain pipe 9 can respond quickly to abnormal situations such as a battery short circuit or fire, effectively prevent the fire from spreading, and protect other equipment in the detection device from damage. The hydraulic cylinder 4 and the pressure plate 5 can accurately control the pressure applied to the battery, thereby accurately evaluating the battery's compressive performance.

[0041] In a further preferred embodiment of the present invention, a fixing plate 2 and a support plate 11 are fixedly installed in the box body 1, and the fixing plate 2 and the support plate 11 are respectively located above and below the placement box 3, and the support plate 11 is fixedly connected to the hydraulic cylinder 4 and the discharge pipe 9, and a pump body 10 is fixedly installed on the top of the support plate 11, and the two ends of the pump body 10 are respectively connected to the perfluorohexanone storage tank 8 and the discharge pipe 9.

[0042] In this embodiment, when the arc light detection device 6 or the smoke detector 7 detects an abnormal situation, the pump body 10 is started to quickly release the fire extinguishing agent in the perfluorohexanone storage tank 8 to the fire point through the discharge pipe 9 to achieve rapid fire extinguishing. By adding the pump body 10, the fire extinguishing agent is released quickly and accurately, and the fire extinguishing efficiency and accuracy are improved. The close connection between the pump body 10, the storage tank 8 and the discharge pipe 9 ensures the stability and reliability of the fire extinguishing system.

[0043] In a further preferred embodiment of the present invention, the support plate 11 separates the box body 1 into a detection chamber and an operation chamber, a partition 12 is fixedly installed in the operation chamber, the partition 12 separates the operation chamber into a purification chamber and a connecting chamber, a plurality of baffles 13 are fixedly installed in the purification chamber, and the plurality of baffles 13 separate the purification chamber into a serpentine cavity, a fan 14 is installed in the operation chamber, and both ends of the fan 14 are respectively connected to the detection chamber and the purification chamber.

[0044] In this embodiment, during the detection process, when the battery is squeezed and deformed and damaged, the battery will release harmful gases. Therefore, when the harmful gases are leaked, the fan 14 is started to suck the harmful gases in the detection chamber into the purification chamber. The harmful gases are fully in contact with the adsorptive material in the serpentine cavity and are preliminarily purified. The purified gases are discharged through the exhaust pipe 17 and further purified by other purification equipment before being discharged safely. By setting up the purification chamber and the serpentine cavity and equipping with adsorptive materials, the harmful gases generated during the detection process are effectively purified, protecting the health of the operators and the safety of the environment. The introduction of the fan 14 provides power for the flow of the gas, ensuring the smooth progress of the purification process. The reasonable layout of the support plate 11 and the partition 12 not only improves the space utilization rate of the device, but also achieves isolation between the detection area and the operation area.

[0045] In a further preferred embodiment of the present invention, an air inlet pipe 15 is fixedly installed on one side of the box body 1, the air inlet pipe 15 is connected to the detection cavity, and a plurality of silicone strips 16 for sealing the air inlet pipe 15 are installed in the air inlet pipe 15, and a controller 79 is installed on one side of the box body 1.

[0046] In this embodiment, during the detection process, the fan 14 is started, and the harmful gas in the detection chamber is sucked into the purification chamber for purification. At the same time, due to the negative pressure formed in the detection chamber, the silicone strip 16 in the air inlet pipe 15 is opened inward, allowing external air to enter the detection chamber through the air inlet pipe 15 to supplement the air sucked away by the fan 14, forming a gas cycle. When the fan 14 stops running, the silicone strip 16 automatically resets to seal the air inlet pipe 15 to prevent the gas in the box 1 from leaking out through the air inlet pipe 15;

[0047] The controller 79 receives signals from sensors such as the arc detection equipment 6 and the smoke detector 7, and controls the start and stop of components such as the fan 14 and the hydraulic cylinder 4 according to the signal status. At the same time, the controller 79 can also adjust the speed of the fan 14, the pressure of the hydraulic cylinder 4 and other parameters according to the preset program or the operator's instructions to meet different detection requirements. By setting the air inlet pipe 15 and the fan 14, the circulation and purification of the gas in the detection chamber are realized, ensuring the timely discharge of harmful gases and the replenishment of fresh air during the detection process. The setting of the purification chamber and the adsorptive material further improves the gas purification effect, protects the health of the operator and the safety of the environment, and uses the silicone strip 16 as a sealing element. When the fan 14 stops running, it can automatically reset and seal the air inlet pipe 15, effectively preventing the leakage of harmful gases in the box 1, and improving the sealing performance and safety of the device.

[0048] In a further preferred embodiment of the present invention, an exhaust pipe 17 is fixedly installed on the top of the box body 1. The exhaust pipe 17 is communicated with the purification chamber. An annular plate 18 and a bracket 19 are fixedly installed in the exhaust pipe 17. A sealing plate 21 for sealing the annular plate 18 is placed in the annular plate 18. A return spring 20 for resetting the sealing plate 21 is installed on the bracket 19 and the sealing plate 21.

[0049] In this embodiment, the fan 14 sucks the harmful gas in the detection chamber into the purification chamber for purification treatment. The purified gas pushes up the sealing plate 21 under the action of pressure, exposing the through-hole of the annular plate 18, and the gas can pass through the exhaust pipe 17 for further purification treatment or discharge. When the gas is discharged, the return spring 20 stretches and drives the sealing plate 21 to reset, resealing the through-hole of the annular plate 18 to prevent the leakage of harmful gas or incompletely purified gas. By setting components such as the exhaust pipe 17, the annular plate 18, the bracket 19, the return spring 20, and the sealing plate 21, precise control of the discharge of the purified gas is achieved. Only when the gas has been purified can it push up the sealing plate 21 and be discharged through the exhaust pipe 17, ensuring the safety of the discharged gas. Through the combined use of the return spring 20 and the sealing plate 21, it is ensured that when the gas does not need to be discharged, the through-hole of the annular plate 18 is effectively sealed, preventing the leakage of harmful gas or incompletely purified gas, and improving the sealing performance and safety of the device.

[0050] In a further preferred embodiment of the present invention, conical blocks 22 for guiding the gas flow are installed on both the bracket 19 and the air inlet pipe 15. One side of the conical block 22 located in the air inlet pipe 15 is in contact with a plurality of the silica gel strips 16.

[0051] In this embodiment, when the fan 14 is started, a negative pressure is formed in the detection chamber. The silica gel strips 16 in the air inlet pipe 15 are guided by the conical block 22 to open inward under the action of the negative pressure, allowing external air to enter the detection chamber through the air inlet pipe 15. The purified gas is discharged through the exhaust pipe 17 under the action of pressure, and the conical block 22 therein ensures that the gas flows out smoothly without obstruction.

[0052] In a further preferred embodiment of the present invention, the opening and closing mechanism includes: a protective box 23 fixedly installed on the box body 1 and arranged in a U-shape; a cover plate 24 slidably arranged at the bottom of the inner wall of the protective box 23 for sealing the inlet and outlet of the box body 1; a limit frame 25 rotatably installed on the top of the box body 1; an electric telescopic rod 26 fixedly installed on the top of the box body 1 for driving the cover plate 24 to move, and a steel wire rope 27 connected to the electric telescopic rod 26 and the cover plate 24. The steel wire rope 27 bypasses the limit frame 25.

[0053] In this embodiment, when the inlet and outlet need to be opened, the electric telescopic rod 26 is retracted, driving the steel wire 27 to move synchronously. After the steel wire 27 bypasses the limit frame 25, it pulls the cover plate 24 to slide upward along the protection box 23 until the inlet and outlet are completely exposed; when the inlet and outlet need to be closed, the electric telescopic rod 26 is extended, and the steel wire 27 moves in the opposite direction under the pulling force of the electric telescopic rod. At this time, the steel wire 27 pushes the cover plate 24 to slide downward along the protection box 23 until the cover plate 24 is tightly attached to the bottom of the protection box 23, and the inlet and outlet are completely sealed. The automatic opening and closing control of the cover plate 24 is realized by the drive of the electric telescopic rod 26. This design not only improves the operating efficiency, but also reduces the labor intensity of the operator. The cover plate 24 can be tightly attached to the bottom and side of the protection box 23 during the sliding process, effectively preventing harmful gases or incompletely purified gases from leaking from the inlet and outlet.

[0054] In a further preferred embodiment of the present invention, a connecting wheel 28 is fixedly installed on the top of the box body 1, and the connecting wheel 28 is used to guide the wire rope 27 to move smoothly. A connecting rod 29 is fixedly installed in the protective box 23, and the connecting rod 29 slides through the cover plate 24, and a connecting spring 30 is sleeved on the connecting rod 29, and the bottom end of the connecting spring 30 is in close contact with the cover plate 24.

[0055] In this embodiment, when the electric telescopic rod 26 is retracted, the steel wire rope 27 bypasses the limit frame 25 and the connecting wheel 28, and smoothly pulls the cover plate 24 to slide upward along the connecting rod 29. At this time, the connecting spring 30 is compressed to provide an upward thrust for the cover plate 24, while ensuring that it remains stable during the sliding process. When the cover plate 24 slides to the specified position, the inlet and outlet are exposed;

[0056] When the electric telescopic rod 26 is extended, the wire rope 27 moves in the opposite direction, pushing the cover 24 to slide downward along the connecting rod 29. At this time, the connecting spring 30 gradually returns to its original shape, providing a downward pulling force for the cover 24, ensuring that it fits tightly against the bottom of the protective box 23, and completely sealing the inlet and outlet. The introduction of the connecting wheel 28 ensures the stability of the wire rope 27 during movement, thereby improving the sliding stability of the cover 24, helping to reduce the shaking and noise of the cover 24 during the sliding process, and improving the overall performance of the device.

[0057] In a further preferred embodiment of the present invention, a discharge box 39 for placing tested batteries is provided in the box body 1, a guide frame 40 is fixedly installed on one side of the box body 1, the guide frame 40 is located on one side of the outlet, and a roller 41 is rotatably installed in the guide frame 40.

[0058] In this embodiment, after the battery inspection is completed, the batteries in the placement box 3 are moved to the discharge box 39 through a two-stage moving mechanism. At this time, the discharge box 39 is filled with inspected batteries, and then the discharge box 39 is pushed to move along the guide frame 40. During the movement, the roller 41 plays an auxiliary and supporting role to ensure that the discharge box 39 can smoothly enter the guide frame 40 and continue to move forward to facilitate the discharge of the batteries. At this time, the operator can easily collect and process these inspected batteries. By introducing structures such as the discharge box 39, the guide frame 40 and the roller 41, the automatic discharge of the batteries can be realized, thereby effectively reducing the steps and time of manual operation and improving the efficiency and accuracy of the inspection process.

[0059] In a further preferred embodiment of the present invention, a fixed block 65 is fixedly installed in the placement box 3, a fixed rod 66 is slidably provided on the fixed block 65, a push block 68 for limiting the battery is fixedly installed at one end of the fixed rod 66, a fixed spring 67 is sleeved on the fixed rod 66, and the two ends of the fixed spring 67 are fixedly connected to the fixed block 65 and the push block 68 respectively.

[0060] In this embodiment, when it is necessary to place the battery in the placement box 3, the operator can push the battery in from the opening. At this time, the push block 68 will move backward along the fixing rod 66 under the push of the battery and compress the fixing spring 67. When the battery is completely placed in the placement box 3, the fixing spring 67 will return to its original shape and push the push block 68 to fit the side of the battery, thereby limiting the battery in the placement box 3. The combined use of the push block 68 and the fixing spring 67 ensures the stability of the battery in the placement box 3. Even if the placement box 3 moves up and down or tilts, the battery will not fall off from the opening, thereby improving the safety and reliability of the device.

[0061] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0062] In another embodiment of the present invention, a two-stage moving mechanism for moving the battery is provided at the bottom of the support plate 11, and the two-stage moving mechanism includes: a one-way screw 31 rotatably installed at the bottom of the support plate 11, a slider 32 is threadedly sleeved on the one-way screw 31, and the slider 32 is in sliding contact with the bottom of the support plate 11; a transverse guide rail 33 installed on the slider 32; a bidirectional electric guide rail 34 provided on the output block of the transverse guide rail 33; two clamping blocks 35 for clamping the battery installed on the two output blocks of the bidirectional electric guide rail 34, and a connecting mechanism provided on the transverse guide rail 33 and the support plate 11 for driving the output block of the transverse guide rail 33 to move.

[0063] In this embodiment, when the battery needs to be moved, the one-way screw 31 is first driven to rotate so that the slider 32 and the transverse guide rail 33, the two-way electric guide rail 34 and the clamp 35 thereon are moved to the two sides of the battery. Then, the two-way electric guide rail 34 is started so that its two output blocks move toward each other, thereby driving the clamp 35 to clamp the battery. After clamping the battery, the slider 32 is reset, and the battery is placed on the discharge box 39 to facilitate the subsequent discharge of the battery out of the box 1. Through the design of the two-stage moving mechanism, the operator can flexibly move the position of the clamp 35 by adjusting the one-way screw 31 and the connecting mechanism to adapt to batteries of different sizes and positions. The design of the clamp 35 ensures the stability of the battery during movement and avoids safety hazards caused by shaking or tilting.

[0064] In another embodiment of the present invention, the connecting mechanism includes: a rack 73 fixedly mounted on the bottom of the support plate 11; a round rod 74 and a mounting frame rotatably mounted on the top of the transverse guide rail 33; a driven gear 75 rotatably mounted on the mounting frame; bevel gears 76 fixedly mounted on the round rod 74 and the output rod of the driven gear 75, respectively, and the two bevel gears 76 are meshed with each other; a connecting sprocket 77 fixedly mounted on the round rod 74 and the output rod of the transverse guide rail 33, respectively; and a connecting chain 78 mounted on the two connecting sprockets 77.

[0065] In this embodiment, when the one-way screw 31 drives the slider 32 to slide, the driven gear 75 contacts and rotates with the rack 73, and the rotational power is transmitted to the round rod 74 through the bevel gear 76, and then transmitted to the output rod of the transverse guide 33 through the connecting sprocket 77 and the connecting chain 78. Since the output rod of the transverse guide 33 is a screw, it will drive the output block of the transverse guide 33 to move. In this way, while the slider 32 drives the transverse guide 33 to slide, the output block of the transverse guide 33 also synchronously drives the bidirectional electric guide 34 to move, realizing a two-stage moving operation. By introducing transmission elements such as the rack 73, the driven gear 75, the bevel gear 76, the connecting sprocket 77 and the connecting chain 78, this embodiment realizes a transmission chain from the one-way screw 31 to the output rod of the transverse guide 33. This design improves the transmission efficiency and ensures the accuracy and stability of power transmission.

[0066] In another embodiment of the present invention, two threaded rods 36 are rotatably installed on the bottom of the inner wall of the box body 1, two threaded tubes 37 are slidably provided on the fixed plate 2, and the two threaded tubes 37 are respectively threadedly sleeved on the two threaded rods 36, and the top ends of the two threaded tubes 37 are fixedly installed with connecting plates 54, the connecting plate 54 on the left side is fixedly connected to the placement box 3, and a rectangular rod 38 is fixedly installed on the bottom of the connecting plate 54, and the rectangular rod 38 slides through the fixed plate 2.

[0067] In this embodiment, when the two-stage moving mechanism is in operation, the clamp block 35 will move to the left or right to clamp or release the battery. In this embodiment, when the clamp block 35 moves to the left, the two threaded rods 36 will rotate synchronously, so that the placement box 3 slides up, and the discharge box 39 slides down, so that the connection plate 54 and the placement box 3 on the left side move upward and close to the clamp block 35, so that the clamp block 35 can clamp the battery. By designing the threaded rod 36 and the two-stage moving mechanism in linkage, this embodiment realizes the synchronous control of the movement of the clamp block 35 and the lifting and lowering of the placement box 3. This design improves the degree of automation, reduces the steps and time of manual operation, and plays a guiding and stabilizing role through the design of the rectangular rod 38, ensuring the stability of the connection plate 54 and the threaded barrel 37 during the movement process, which helps to avoid safety hazards caused by shaking or tilting during the movement.

[0068] In another embodiment of the present invention, a rotating rod 42 is rotatably installed on one side of the box body 1, a connecting sprocket 43 is provided on one side of the inner wall of the box body 1 and the one-way screw 31, a connecting chain 44 is sleeved on the two connecting sprockets 43, a bevel gear 45 is fixedly sleeved on the connecting sprocket 43 located on one side of the inner wall of the box body 1 and the top of the rotating rod 42, and the two bevel gears 45 are meshed with each other.

[0069] In this embodiment, when the one-way screw 31 rotates, it will drive the slider 32 to slide thereon. Since the slider 32 is fixedly connected to the output block of the transverse guide rail 33, the sliding of the slider 32 will drive the transverse guide rail 33 to move. At the same time, according to the previous description, the output rod of the transverse guide rail 33 will drive the output block thereon to move. In this way, the operation of the two-stage moving mechanism is realized. By introducing transmission elements such as bevel gears 45, connecting sprockets 43 and connecting chains 44, this embodiment realizes a transmission chain from the rotating rod 42 to the one-way screw 31. This design improves the transmission efficiency and ensures the accuracy and stability of power transmission.

[0070] In another embodiment of the present invention, a driving mechanism is provided on the rotating rod 42 and the threaded rod 36 for synchronously driving the threaded rod 36 and the one-way screw 31 to rotate, and the driving mechanism includes: a motor 49 fixedly installed at the bottom of the fixed plate 2; a plurality of connecting sprockets 46 fixedly mounted on the threaded rod 36, the rotating rod 42 and the output shaft of the motor 49 respectively; a connecting chain 47 mounted on the plurality of connecting sprockets 46; and a limiting wheel 48 rotatably installed at the bottom of the inner wall of the box body 1 for limiting the connecting chain 47.

[0071] In this embodiment, when the motor 1 49 is started, its output shaft drives a connecting sprocket 2 46 to rotate. Since the connecting sprocket 2 46 is connected to the connecting sprocket 2 46 sleeved on the threaded rod 36 and the rotating rod 42 through the connecting chain 2 47, the rotational power is transmitted to the threaded rod 36 and the rotating rod 42, so that they rotate synchronously.

[0072] As mentioned above, the rotation of the threaded rod 36 will drive the threaded barrel 37 to move along its length direction. In this embodiment, there are two threaded barrels 37 respectively mounted on the two threaded rods 36, and their movement directions are opposite (this can be achieved by changing the rotation direction of the thread). When the threaded rod 36 rotates, one threaded barrel 37 will drive the placement box 3 to slide up, and the other threaded barrel 37 will drive the discharge box 39 to slide down.

[0073] Operation of the two-stage moving mechanism and movement of the battery:

[0074] The rotation of the rotating rod 42 will drive the one-way screw 31 to rotate, thereby causing the slider 32 to slide on the one-way screw 31. When the slider 32 moves to the left, the clamp 35 will clamp the battery. After clamping the battery, the slider 32 will reset (i.e. move in the opposite direction), and at the same time, the placement box 3 will slide down and return to its initial position, and the discharge box 39 will slide up and be ready to receive the battery. At this time, the clamp 35 will place the battery on the discharge box 39, completing the battery movement process.

[0075] In another embodiment of the present invention, a driving wheel 50 is rotatably installed in the box body 1, and the driving wheel 50 is located on one side of the fixed plate 2. The driving wheel 50 is used to move the discharge box 39 out of the box body 1, and a motor 2 51 is fixedly installed on one side of the box body 1. The output shaft of the motor 2 51 is fixedly connected to the rotating shaft of the driving wheel 50, and a frosting plate 52 is installed at the bottom of the discharge box 39, and a guide wheel 53 is rotatably installed on the top of the connecting plate 54, and an electromagnetic suction cup 55 for fixing the discharge box 39 is provided in the connecting plate 54.

[0076] In this embodiment, when the discharge box 39 needs to be discharged, the electromagnetic suction cup 55 is first powered off to release the fixation of the discharge box 39, and then the threaded rod 36 is driven by the motor 1, so that the threaded cylinder 37 threadedly connected to the threaded rod 36 drives the discharge box 39 to slide down and contact the driving wheel 50. Since the grinding plate 52 increases the friction, the driving wheel 50 can more effectively drive the discharge box 39 to move. Finally, the motor 2 51 is started to drive the driving wheel 50 to rotate, thereby bringing the discharge box 39 out of the box body 1. By introducing the motor 2 51 and The electromagnetic suction cup 55 and other components realize the automatic discharge of the discharge box 39 in this embodiment. The operator only needs to control the switch of the motor and the on and off of the electromagnetic suction cup 55 to realize the fixation and release of the discharge box 39 and the discharge process. No additional manual operation is required. The design of the electromagnetic suction cup 55 ensures the stability of the discharge box 39 during movement. When the discharge box 39 is fixed, it is not easy to shake or fall off even if it is disturbed by external force. At the same time, the auxiliary guidance of the guide wheel 53 further enhances the smooth movement of the discharge box 39.

[0077] In another embodiment of the present invention, a connecting groove is provided at the bottom of the discharge box 39, a limiting plate 56 for limiting the discharge box 39 is rotatably provided in the connecting groove, a connecting spring 57 is fixedly installed on one side of the inner wall of the connecting groove and the limiting plate 56, and an elastic metal sheet 58 is installed in the limiting plate 56 and the connecting groove.

[0078] In this embodiment, when the driving wheel 50 drives the discharge box 39 to move, the discharge box 39 will move along a preset path. During the movement, the limit plate 56 will first contact one side of the connecting plate 54. Due to the pressing effect of the connecting plate 54, the limit plate 56 will be subjected to an inward force and stretch the connecting spring 57 to rotate. As the discharge box 39 continues to move, the limit plate 56 will gradually rotate into the connecting groove, and make the two elastic metal sheets 58 contact each other and clamp together. At this time, the limit plate 56 is fixed in the connecting groove.

[0079] In another embodiment of the present invention, a drainage hole is opened on one side of the discharge box 39, a connecting spring 2 59 is installed on one side of the discharge box 39, an L-shaped block 60 for sealing the drainage hole is fixedly installed on the bottom end of the connecting spring 2 59, a rectangular frame 61 is fixedly installed on one side of the discharge box 39, a support rod 62 for limiting the L-shaped block 60 is slidably installed on the rectangular frame 61, the top of the support rod 62 is in close contact with the L-shaped block 60, an elastic metal sheet 2 63 is fixedly installed on the bottom end of the support rod 62, and a push rod 64 for pushing the elastic metal sheet 2 63 is fixedly installed on one side of the connecting plate 54.

[0080] In this embodiment, when the battery leaks, the battery is first placed in the discharge box 39. A discharge hole is provided on one side of the discharge box 39, and the discharge hole allows the liquid leaked from the battery to flow out. In order to ensure that the discharge hole is not opened under normal circumstances, the L-shaped block 60 is supported by the second connecting spring 59 and tightly blocked on the discharge hole. Under normal circumstances, the second connecting spring 59 is in a compressed state, and the L-shaped block 60 is set above the discharge hole. At the same time, the support rod 62 limits the L-shaped block 60, thereby ensuring that it does not block the discharge hole, so that the discharge hole is exposed;

[0081] When the discharge box 39 slides along the connecting plate 54 to prepare for discharge out of the box body 1, the push rod 64 will contact and limit the elastic metal sheet 2 63, so that the elastic metal sheet 2 63 drives the support rod 62 to move to the left, and makes the support rod 62 slide away from the L-shaped block 60. When the support rod 62 slides away from the L-shaped block 60, the connecting spring 2 59 is released, so that the L-shaped block 60 blocks the discharge hole. At the same time, when the support rod 62 slides to the extreme position of the rectangular frame 61, the elastic metal sheet 2 63 is elastically deformed, so that it bypasses the push rod 64 and moves synchronously with the discharge box 39.

[0082] In another embodiment of the present invention, a collecting tray 69 is fixedly installed on the top of the fixed plate 2, and the collecting tray 69 is located between the placement box 3 and the discharge box 39 for collecting the electrolyte discharged from the battery. A drainage box 70 for guiding the electrolyte is fixedly installed on the bottom of the fixed plate 2, and a drip-free membrane 71 is installed in the drainage box 70 and the collecting tray 69. A collecting box 72 for centrally collecting the electrolyte is provided on one side of the box body 1.

[0083] In this embodiment, the collecting tray 69 is located between the placing box 3 and the discharge box 39, and its main function is to collect the electrolyte discharged from the battery. When the battery leaks in the placing box 3, the electrolyte will first drip onto the collecting tray 69, and then be discharged into the discharge box 70, so that it can flow smoothly into the collecting box 72, thereby centrally collecting the electrolyte flowing out of the discharge box 70. Through the setting of the drip-free membrane 71, the electrolyte is not easy to form stable droplets on its surface, but tends to spread out, thereby reducing residue and facilitating the collection of the electrolyte.

[0084] In summary, compared with related technologies, this device not only has the function of battery pressure resistance performance detection, but also integrates safety monitoring and fire extinguishing functions, realizing comprehensive monitoring and protection of the battery performance detection process.
