Description

Technical Field

[0001] This invention relates to the field of energy storage battery life testing technology, specifically to a testing device for energy storage battery life. Background Technology

[0002] Battery testers are primarily used to detect current, voltage, capacity, internal resistance, temperature, and battery cycle life, and provide graphs. Battery testers offer multiple channels and can be started and controlled at a single point, simultaneously testing different models and types of batteries (nickel-metal hydride, nickel-cadmium, lithium-ion, etc.). Battery testers are currently commonly used equipment for battery life testing. The principle behind battery life testing is to measure the ion content on the electrode surface to determine its chemical reactivity, and to infer changes in battery capacity through changes in the electrode plates, thereby determining the battery's health and calculating its lifespan. However, existing battery testers cannot adjust for the ambient temperature during battery testing, resulting in poor accuracy in battery life testing and an inability to test battery range under different temperature conditions.

The operator pulls out the lead wire, clamps the testing clamp onto the battery, and then closes the cover. The winding roller rotates, winding up the excess lead wire to the outside. When testing different batteries, if the lead wire is short, the winding roller will stop rotating after winding the lead wire to a certain length. At this point, the rack drives the second transmission gear to rotate, causing the clutch sleeve to push the clutch head and push post into the storage tank, preventing the clutch sleeve from driving the winding roller. If the battery needs to be removed, the operator opens the cover, allowing the second transmission gear to drive the winding roller to reset and rotate through the clutch sleeve, releasing the lead wire. This ensures that the lead wire is neatly arranged inside the testing chamber and prevents it from getting tangled. Attached Figure Description

[0033] The winding box 10 has a winding roller 24 rotatably connected inside, and a wire 11 is wound around the outside of the winding roller 24. An electronic rotary joint 27 is provided on one side of the inner cavity of the winding box 10. A plug 26 is provided inside the winding roller 24. One end of the wire 11 is connected to one end of the plug 26, and the other end of the plug 26 is connected to one end of the electronic rotary joint 27. A connection end 28 is provided on one side of the winding box 10. One end of the connection end 28 is connected to one end of the plug 26, and the other end of the connection end 28 is electrically connected to the detector 9, which can wind or unwind the wire 11.

[0034] Among them, a protective box 19 is fixedly connected to one side of the working box 13, and a semiconductor cooling chip 18 is fixedly connected to one side of the working box 13 and inside the protective box 19. A fan 21 is provided on one side of the inner cavity of the protective box 19. An outlet hole 22 is provided on one side of the protective box 19 above and below the fan 21. An air inlet hole 20 is provided on the top and bottom of the protective box 19. A clutch sleeve 69 is fixedly connected to one side of the detection box 1 and below the fixing block 4. A second transmission gear 70 is provided inside the clutch sleeve 69. When the cover plate 8 is rotated to the vertical state, the outer side of the fixing plate 6 will contact the second transmission gear 70 through the second transmission gear 70, thereby limiting the fixing plate 6 and causing the cover plate 8 to open to the vertical state.

[0035] Example 2

[0036] Please see Figures 1 to 13The present invention provides a technical solution: a movable groove 29 is provided inside the cover plate 8 and above the winding box 10. A lead screw 30 is rotatably connected inside the movable groove 29. One end of one lead screw 30 is fixedly connected to a transmission rod 32. The other end of the transmission rod 32 is connected to one end of another lead screw 30. The two lead screws 30 are connected by transmission rod 32. A movable block 31 is threaded to the outside of the lead screw 30. The bottom of the movable block 31 extends to the bottom of the cover plate 8 and is provided with a rack 33. A plurality of tooth grooves 35 are provided at the bottom of the rack 33. A first side groove 34 is provided on one side of the rack 33 and a second side groove 36 is provided on the other side of the rack 33. When the rack 33 moves, the second transmission gear 70 can be driven to rotate through the first side groove 34, tooth grooves 35 and second side grooves 36.

[0037] One end of the take-up roller 24 extends to the outside of the take-up box 10 and is fitted with a clutch sleeve 69. A second transmission gear 70 is fitted on the outside of each clutch sleeve 69. Several storage slots 54 are provided inside the take-up roller 24. A support spring 55 is provided on one side of each storage slot 54, and a push post 56 is provided at one end of each support spring 55. Several clutch slots 58 are provided inside the clutch sleeve 69. A clutch head 57 is provided at one end of each push post 56, and one end of each clutch head 57 extends into the clutch slot 58. When the wire 11 is wound around the take-up roller 24 to a specified length, the take-up roller 24 cannot rotate. At this time, the second transmission gear... Wheel 70 drives clutch sleeve 69 to continue rotating, causing clutch head 57 to push push column 56 into storage groove 54, disengaging clutch sleeve 69 from take-up roller 24. This prevents clutch sleeve 69 from driving take-up roller 24 to rotate. When wire 11 needs to be released, second transmission gear 70 drives clutch sleeve 69 to reset and rotate. At this time, support spring 55 pushes push column 56 and clutch head 57 to reset and move, allowing one end of clutch head 57 to be inserted into clutch groove 58. This allows clutch sleeve 69 to connect with take-up roller 24, enabling second transmission gear 70 to drive take-up roller 24 to rotate through clutch sleeve 69.

[0038] Among them, a gear ring 39 is fixedly connected to one side of the detection box 1, a limit block 37 is fixedly connected to the top of the fixing plate 6, a first drive rod 38 is rotatably connected to one side of the limit block 37, a first transmission gear 40 is sleeved on the outer side of the first drive rod 38, the first transmission gear 40 cooperates with the gear ring 39, a transmission groove 41 is opened inside the fixing plate 6, a drive shaft 42 is rotatably connected inside the transmission groove 41, one end of the first drive rod 38 extends to one side of the limit block 37, a transmission pulley 43 connected by belt drive is sleeved on the outer side of both the drive shaft 42 and the first drive rod 38, and a fixing groove 44 is opened inside the cover plate 8, a transmission shaft 45 is rotatably connected to the bottom of the inner cavity of the fixing groove 44, and a meshing cone is sleeved on the outer side of both the transmission shaft 45 and the second drive rod 46. The gear 48 and the inner cavity of the fixed groove 44 are rotatably connected to the second drive rod 46. The outer side of the second drive rod 46 and the drive shaft 42 are both fitted with the first pulley 47 connected by belt drive. The bottom of the inner cavity of the fixed groove 44 and the side of the drive shaft 45 are rotatably connected to the first worm 49. The outer side of the first worm 49 and the drive shaft 45 are both fitted with the second pulley 50 connected by belt drive. The inner cavity of the fixed groove 44 is rotatably connected to the fixed shaft 51. The outer side of the fixed shaft 51 is fitted with the first worm wheel 52 connected by drive to the first worm 49. The lead screw 30 and the outer side of the fixed shaft 51 are fitted with the third pulley 53 connected by belt drive. It can rotate with the cover plate 8, thereby driving the rack 33 to move, and thus driving the take-up roller 24 to rotate.

[0039] Each of the following components is equipped with a mounting block 60 fixedly connected to one side of the winding box 10. Each mounting block 60 has a mounting groove 59 on its top, and a mounting strip 61 is placed inside each mounting groove 59. The top of each mounting strip 61 is connected to the bottom of the cover plate 8. Each mounting block 60 has a connecting groove 66 located inside and below the mounting groove 59. Each connecting groove 66 has a bidirectional threaded rod 63 rotatably connected inside. A second worm gear 67 is fitted onto the outer side of each bidirectional threaded rod 63. A second worm 68 is rotatably connected to the top of the inner cavity of each connecting groove 66. The second worm 68 is connected to the second worm gear 67. Both ends of the bidirectional threaded rod 63 extend into two sliding grooves 62. A locking post 64 is threaded onto the outer side of the bidirectional threaded rod 63 at opposite thread directions. Each mounting strip 61 has a locking groove 65 on both sides, and one end of each locking post 64 extends into the locking groove 65. The bottom end of each second worm 68 extends below the mounting block 60, thus limiting the movement of the detector 9 and the winding box 10.

[0040] The cover plate 8 is fixedly connected to one side with a first magnetic block 73, and the detection box 1 is provided with a second magnetic block 74. The first magnetic block 73 and the second magnetic block 74 are magnetically attracted to each other. Through the mutual magnetic attraction between the first magnetic block 73 and the second magnetic block 74, the cover plate 8 can be limited.

[0041] In summary, when using this energy storage battery life testing equipment to test the battery's lifespan at different temperatures, the battery is placed inside the testing chamber 3. The telescopic end of the electric telescopic rod 71 then pushes the pressure plate 72 to move and limit the battery. The detector 9 and the winding box 10 are then placed on one side of the cover plate 8, so that the mounting strip 61 is located inside the mounting groove 59. The operator then rotates the second worm gear 68, which drives the bidirectional threaded rod 63 to rotate via the second worm wheel 67, causing one end of the locking pin 64 to insert into the locking groove 65, thus fixing the detector 9. The operator then pulls out the wire 11 and clamps the testing clamp 12 onto the battery. At this point, the operator closes the cover plate 8, so that the cover plate 8 is connected to the fixing plate via the connecting block 7. 6 drives the rotating rod 5 to rotate. When the first transmission gear 40 moves, the gear ring 39 causes the first transmission gear 40 to rotate. The first transmission gear 40, through the first drive rod 38, drives the transmission pulley 43 to rotate, causing the drive shaft 42 to rotate. The drive shaft 42, through the first pulley 47, drives the second drive rod 46 to rotate, causing the second drive rod 46, through the bevel gear 48, drives the transmission shaft 45 to rotate. The transmission shaft 45, through the second pulley 50, drives the first worm gear 49 to rotate, causing the first worm gear 49, through the first worm wheel 52, drives the fixed shaft 51 to rotate. The fixed shaft 51, through the third pulley 53, drives the lead screw 30 to rotate, causing the moving block 31 to move the rack 33, which in turn drives the second transmission gear 70 to rotate. The movement causes the second transmission gear 70 to drive the take-up roller 24 to rotate via the clutch sleeve 69, winding up the excess wire 11 on the outside of the wire 11. When testing different batteries, if the extension length of the wire 11 is short, the take-up roller 24 cannot rotate after winding the wire 11 to a certain length. At this time, the rack 33 drives the second transmission gear 70 to rotate, causing the clutch sleeve 69 to push the clutch head 57 and push post 56 into the storage tank 54, so that the clutch sleeve 69 cannot drive the take-up roller 24 to rotate. Then, the liquid inside the working box 13 can be heated by starting the heating rod 14, and the liquid inside the working box 13 is discharged into the liquid chamber 17 by the first liquid pump 15, and the liquid inside the liquid chamber 17 is discharged by the second liquid pump 16. The liquid is reheated inside the working chamber 13. A temperature sensor installed inside the detection chamber 3 monitors the temperature inside the chamber to ensure the ambient temperature remains within the test range. The thermoelectric cooler 18 is activated to cool the liquid inside the working chamber 13. Fan 21 starts, drawing outside air into the protective chamber 19 through the air inlet 20 to dissipate heat from the heat-conducting surface of the thermoelectric cooler 18. The hot air inside the protective chamber 19 is then exhausted to the outside through the outlet 22. The first liquid pump 15 pumps the liquid from the working chamber 13 into the liquid chamber 17, and the second liquid pump 16 pumps the liquid from the liquid chamber 17 into the working chamber 13 for further cooling.Ensure the test environment temperature inside the test chamber 3 is within the test temperature range. If the battery needs to be removed, the operator opens the cover plate 8. At this time, the cover plate 8 drives the rotating rod 5 to reset and rotate via the connecting block 7 and the fixed plate 6. When the first transmission gear 40 resets and moves, the gear ring 39 causes the first transmission gear 40 to reset and rotate. This causes the first transmission gear 40 to drive the transmission pulley 43 to reset and rotate via the first drive rod 38, causing the drive shaft 42 to reset and rotate. This causes the drive shaft 42 to drive the second drive rod 46 to reset and rotate via the first pulley 47, causing the second drive rod 46 to drive the transmission shaft 45 to reset and rotate via the bevel gear 48, causing the transmission shaft 45 to drive the first worm gear 49 to reset and rotate via the second pulley 50, causing the first worm gear 49 to drive the fixed shaft 51 to reset and rotate via the first worm wheel 52, causing the fixed shaft 51 to drive the lead screw 30 to reset and rotate via the third pulley 53, causing the moving block 31 to drive the rack 33 to reset and move, causing the rack 33 to drive... The second transmission gear 70 resets and rotates, causing the take-up roller 24 to reset and rotate via the clutch sleeve 69, releasing the lead wire 11. The operator then removes the testing clamp 12 from the battery. Next, the operator resets and rotates the second worm gear 68, causing it to drive the bidirectional threaded rod 63 to reset and rotate via the second worm wheel 67. This moves one end of the locking pin 64 out of the locking slot 65, releasing the detector 9 from its limit and removing it from the cover plate 8. The operator then rotates the second transmission gear 70, causing the take-up roller 24 to rotate via the clutch sleeve 69, winding the lead wire 11 around the outside of the take-up roller 24. The telescopic end of the electric telescopic rod 71 then moves the pressure plate 72 to reset and move, releasing the battery from its limit and allowing it to be removed from the testing chamber 3. The detector 9 can then be removed for testing other batteries. During testing, the battery can be placed inside the testing chamber 3 to test its range under different temperature conditions.
