The driving plate is arranged for docking the test top plate 28, and the sliding rod 222 ensures the stability of the test top plate 28 when it moves up and down.

[0038] As a specific technical solution of this embodiment, the test bottom plate 13 is fixed to the top of the tooling base 11 by a bottom plate screw 131, and the test top plate 28 is located above the test bottom plate 13. A slot 283 movably connected to the plug-in board 224 is provided on one side of the test top plate 28. When the test top plate 28 needs to be replaced, the slot 283 of the test top plate 28 is aligned with and inserted into the plug-in board 224 to complete the preliminary top plate of the test top plate 28. Then, the test top plate 28 is moved up to contact the docking plate 271. When the test bottom plate 13 needs to be replaced, the bottom plate screws 131 can be removed to replace the test bottom plates 13 of different specifications to adapt to the battery pack protection board tests of different specifications.

[0039] As a specific technical solution of this embodiment, the top of the test top plate 28 is provided with a number of not less than one connecting groove 281, and the inner walls around the connecting groove 281 are all provided with positioning grooves 282. The top of the inner wall of the positioning groove 282 is provided with an inclined surface. The top of the docking plate 271 is provided with a number of threaded grooves 272 that is the same as the number of connecting grooves 281. The bottom of the docking plate 271 is provided with a square groove 273 connected to the threaded groove 272. The internal thread sleeve of the threaded groove 272 is provided with a top plate screw 274. The internal movably sleeve of the square groove 273 is provided with a pressure block 275. The top of the pressure block 275 is provided with a turntable 276 that is rotatably sleeved inside the top plate screw 274. The internal movably sleeve of the threaded groove 272 is provided with a pressure block 275. The spring and the setting of the threaded groove 272 cooperate with the square groove 273, so that when the top plate screw 274 is rotated, the pressure block 275 will not be driven to rotate, so that the top plate screw 274 can only drive the pressure block 275 to rise or fall through the turntable 276. The setting of the spring inside the threaded groove 272 continuously applies a resistance force to the top plate screw 274. At the same time, as the top plate screw 274 descends, the resistance force will be further strengthened, thereby ensuring the stability of the top plate screw 274 and avoiding the top plate screw 274 from rotating. When in use, after the test top plate 28 is connected to the top plate driving plate 223, the test top plate 28 is lifted to contact the docking plate 271, and the connecting groove 281 at the top of the test top plate 28 is aligned with the docking tube 3 and inserted one by one. The connection operation can be started by turning the top plate screw 274 with a screwdriver.

[0040] As a specific technical solution of this embodiment, movable holes 31 are provided on all sides of the docking tube 3, and the clamping block 32 is movably arranged inside the movable hole 31. The number of the clamping block 32 and the movable hole 31 inside the docking tube 3 is four. A driving inclined surface 33 is provided on the top of one side of the clamping block 32, and a positioning inclined surface 34 is provided on the top of the other side. The positioning inclined surface 34 is opposite to the inclined surface at the top of the positioning groove 282. The bottom of the pressing block 275 extends to the inside of the docking tube 3. The bottom of the pressing block 275 is provided with inclined surfaces on all sides, and the inclined surfaces are in contact with the driving inclined surfaces 33. When in use, the top plate screw 274 is turned by a screwdriver, and the top plate screw 274 descends to drive the pressing block 275 to descend, and the pressing block 275 The pressing block 275 descends, so that the inclined surface at the bottom of the pressing block 275 contacts the driving inclined surface 33, so that the driving inclined surface 33 drives the clamping block 32 to retreat, so that the clamping block 32 moves from the inside of the movable hole 31 to the inside of the positioning groove 282. As the pressing block 275 descends, the positioning inclined surface 34 on one side of the clamping block 32 contacts the inclined surface at the top of the positioning groove 282. The design of the positioning inclined surface 34 not only ensures the lateral stability between the positioning groove 282 and the docking tube 3, but also applies an upward force to the positioning groove 282 when the positioning inclined surface 34 contacts the inclined surface at the top of the positioning groove 282, so that the contact between the test top plate 28 and the docking plate 271 is more stable, and the docking plate 271 drives the test top plate 28 to move downward more stably, and the alignment is more precise.

[0041] As a specific technical solution of this embodiment, a slide groove 37 is provided at the bottom of the inner wall of the movable hole 31, and a slider 35 connected to the sliding sleeve 242 inside the slide groove 37 is provided at the bottom of the clamping block 32. The slider 35 and the slide groove 37 are both T-shaped, and a return spring 38 with one end in contact with one side of the slider 35 is movably provided inside the slide groove 37. A plurality of balls 36 are movably nested on the bottom of the clamping block 32 and the slider 35. The slider 35 has balls 36 on the bottom, both sides of the top and both sides. The setting of the balls 36 can reduce the sliding between the arc block and the slide groove 37. The friction force is reduced during the movement of the clamping block 32, so that the clamping block 32 can move smoothly when pushed by the pressure block 275, and the control is more flexible. When the clamping block 32 moves toward the inside of the positioning groove 282, the clamping block 32 drives the slider 35 to compress the reset spring 38. The reset spring 38 is set. When the top plate screw 274 drives the pressure block 275 to rise and break away from the resistance to the clamping block 32, the reset spring 38 rebounds and drives the clamping block 32 to move toward the inside of the movable hole 31 and the docking tube 3, so that the docking tube 3 and the connecting groove 281 can be separated smoothly, which is convenient for replacing the test top plate 28.

[0042] As a specific technical solution of this embodiment, a power interface 12 is provided on one side of the tooling base 11, at least two rocker switches 14 are provided on the front side of the tooling base 11, at least two micro switches 15 are provided on the top of the tooling base 11, and a handle 251 is provided on the end of the connecting rod 25 away from the hinged seat 241. The power interface 12 is connected to the AC power through a power cord to complete the power supply to the test system. The measuring needle 29 on the test top plate 28 is electrically connected to the test system. The two rocker switches 14 are respectively used to control the total power supply of the test system of the two tooling bodies 2, and the two micro switches 15 are respectively used to control the measuring needles 29 on the two test top plates 28 for testing. By flipping the connecting rod 25 with the handle 251, the connecting rod 25 can be controlled to pull the connecting arm 26 to lift the driving rod 27 or push the connecting arm 26 to drive the driving rod 27 to descend.

[0043] To sum up, compared with the large-scale battery pack test jigs on the market, the battery pack protection plate test jig can realize the rising and falling of the test top plate 28 by manually flipping the handle 251. It is manually operated, has a simple and compact structure, low cost of use, and is convenient for later maintenance, inspection and replacement of parts. The two jig bodies 2 and double-station testing ensure the test efficiency. The compact size and small space occupation make it widely applicable to some repair shops to meet the needs of users.

[0044] The design of the positioning bevel 34 of the battery pack protection plate test tooling not only ensures the stability between the positioning groove 282 and the lateral direction of the docking tube 3, but also when the positioning bevel 34 contacts the bevel at the top of the positioning groove 282, it applies an upward force to the positioning groove 282, so that the contact between the test top plate 28 and the docking plate 271 is more stable, and the docking plate 271 drives the test top plate 28 to move downward more stably and the alignment is more precise, thereby ensuring the stability of the tooling and the test efficiency.
