Technical Field
[0001] This utility model relates to the field of solid-state battery testing technology, and in particular to a device for testing the performance of solid-state batteries. Background Technology
[0002] Solid-state batteries are batteries that use solid electrolytes instead of traditional liquid electrolytes. Compared to traditional lithium-ion batteries, solid electrolytes are less flammable, reducing the risk of fire or explosion, and can provide higher energy density, extend device battery life, have a longer cycle life, and perform more stably over a wider temperature range.
[0003] In existing technologies, solid-state batteries are often placed directly on a testing platform during testing. However, the batteries may shift during the testing process, leading to inaccurate test results. Furthermore, solid-state batteries vary in width depending on their specifications and models, requiring the use of matching devices to fix them in place. These devices have limited functionality and low applicability. Utility Model Content

[0013] This invention provides a device for testing the performance of solid-state batteries, which has the following advantages:
[0014] (1) Before testing, place the solid-state battery on the top of the workbench, and then adjust the motor to drive the drive shaft and the two drive bevel gears to rotate. Since the two drive bevel gears mesh with the two driven bevel gears respectively, the two driven bevel gears rotate in opposite directions, which in turn causes the two rotating plates to rotate in opposite directions synchronously. When the two rotating plates rotate in opposite directions, the rollers connected to their top move along the roller grooves opened at the bottom of the clamping plate, so that the two clamping plates move closer to each other synchronously, clamping the solid-state battery located on the top of the workbench, maintaining the fixed state of the solid-state battery test, and improving the accuracy of the test.
[0015] (2) After the solid-state battery is fixed, the moving motor drives the moving screw to rotate, causing the moving base and gantry to move to the right. The sleeve, telescopic rod and puncture needle connected to the gantry move synchronously to the top of the solid-state battery. Then the telescopic rod moves down, driving the connecting plate and puncture needle down until the solid-state battery is punctured. By controlling the timing of the moving motor, multiple puncture tests can be performed on different positions of the solid-state battery. Attached Figure Description

Rotating plates 4 are fixedly connected to the bottom of each of the two connecting shafts 3. Rollers 5 are movably connected to both ends of the top of the rotating plates 4. A driven bevel gear 6 is fixedly connected to the bottom of the rotating plates 4. An adjustment motor 7 is installed on the outer wall of the workbench 1. A drive shaft 8 is fixedly connected to the output end of the adjustment motor 7. Two drive bevel gears 9 are fixedly connected to the outer wall of the drive shaft 8. Multiple limit grooves 10 are provided on the top of the workbench 1. Limit blocks 11 are provided inside each of the multiple limit grooves 10. The top of the limit blocks 11 is fixed... A clamping plate 12 is connected to the bottom of two limiting blocks 11 on the same side, and a base plate 13 is fixedly connected to the bottom of the base plate 13. A roller groove 14 is opened at the bottom of the base plate 13, and the roller 5 is located inside the roller groove 14. Before testing, the solid-state battery is placed on the top of the workbench 1. Then, the motor 7 is adjusted to drive the drive shaft 8 and the two drive bevel gears 9 to rotate. Since the two drive bevel gears 9 are respectively engaged with the two driven bevel gears 6, the two driven bevel gears 6 rotate in opposite directions, which in turn causes the two rotating plates 4 to rotate in opposite directions synchronously. When the two rotating plates 4 rotate in opposite directions, the roller 5 movably connected to the top of them moves along the roller groove 14 opened at the bottom of the clamping plate 12, so that the two clamping plates 12 move closer to each other synchronously, clamping the solid-state battery located on the top of the workbench 1, keeping the solid-state battery in a fixed state for testing, and improving the accuracy of the test.
[0026] The outer walls of the two driving bevel gears 9 mesh with the outer walls of the two driven bevel gears 6 respectively, and the other end of the drive shaft 8 is movably connected to the inner wall of the adjustment chamber 2.
[0027] Both ends of the two base plates 13 are movably connected to pulleys 15. The inner walls of the adjustment chamber 2 are provided with pulley grooves 16 on both sides. The pulleys 15 are located inside the pulley grooves 16 to reduce the resistance to the movement of the two base plates 13.

After the solid-state battery is fixed, the moving motor 19 drives the moving screw 20 to rotate, causing the moving base 21 and the gantry 22 to move to the right. The sleeve 23 and the telescopic rod 24 connected to the gantry 22 and the puncture needle 26 move synchronously to the top of the solid-state battery. Then the telescopic rod 24 moves down, causing the connecting plate 25 and the puncture needle 26 to move down until the solid-state battery is punctured. By controlling the timing of the operation of the moving motor 19, multiple puncture tests can be performed on different positions of the solid-state battery.
[0030] The inner wall of the gantry 22 is provided with a lifting groove 27, and there are two lifting grooves 27. Both ends of the connecting plate 25 are fixedly connected with lifting blocks 28.
