[0024] Please refer to Figures 1-6 , the present utility model provides the following embodiments:

[0025] A battery module withstand voltage test device, comprising a test base 1, a first bearing plate 2 and a second bearing plate 3. An activity groove is formed at the top of the test base 1. The first bearing plate 2 is slidably installed in the activity groove, and the top end of the first bearing plate 2 extends out of the activity groove. Two symmetrically arranged U-shaped locks 4 are fixedly connected to the right side of the first bearing plate 2. Rotating shafts 5 are rotatably installed in both of the two U-shaped locks 4. Two symmetrically arranged side blades 6 are fixedly connected to the left side of the second bearing plate 3. The other end of the side blade 6 is rotatably installed on the rotating shaft 5. The bottom of the second bearing plate 3 slides on the top of the test base 1, and the top surfaces of the first bearing plate 2 and the second bearing plate 3 are flush. A pressure measuring component is installed on the top of the test base 1. A notch is formed on the right side of the test base 1, and a collection box 7 is arranged in the notch. The collection box 7 is located right below the second bearing plate 3.

[0026] Specifically, a displacement lead screw 8 is rotatably installed in the activity groove. Two parallel limit rods 9 are fixedly connected in the activity groove. The first bearing plate 2 is threadedly installed on the displacement lead screw 8, and the first bearing plate 2 is slidably sleeved on the two limit rods 9. A stepping motor 10 is fixedly installed on the left side of the test base 1, and the output end of the stepping motor 10 is fixedly connected to the displacement lead screw 8.

[0027] Specifically, walking shafts 701 are fixedly installed on the front and rear sides of the collection box 7. Moving wheels 702 are rotatably installed at the ends of the walking shafts 701 far away from the collection box 7. A guiding groove 101 communicating with the notch is formed on the right side of the test base 1. The collection box 7 extends into the notch, and the walking shafts 701 slide into the guiding groove 101. The bottom of the moving wheel 702 is flush with the bottom of the test base 1, so that the placement position of the collection box 7 is relatively accurate, and the moving wheel 702 can adopt a self-locking walking wheel to prevent the collection box 7 from being easily moved during material collection.

[0028] Specifically, the pressure measuring component includes an electric telescopic rod 11, a span frame 12, a vertical seat 13 and a pressure plate 14. The electric telescopic rod 11 is fixedly installed on the test base 1, and the output end of the electric telescopic rod 11 is fixedly connected to the span frame 12. The bottom of the span frame 12 is fixedly connected to the vertical seat 13, and the bottom end of the vertical seat 13 is fixedly connected to the pressure plate 14. The pressure plate 14 is located above the activity groove.

[0029] The specific implementation manner of this embodiment is as follows: Place the battery module to be tested on the tops of the first bearing plate 2 and the second bearing plate 3, that is, the battery module to be tested is located directly below the pressure plate 14. The electric telescopic rod 11 works to drive the span frame 12 to move downward, and then the vertical seat 13 and the pressure plate 14 move downward together. The pressure plate 14 presses the battery module to achieve the compressive test of the battery module, and the detection operation is relatively simple;

[0030] After the test is completed, the electric telescopic rod 11 drives the pressure plate 14 to move upward and reset. The stepping motor 10 operates to drive the displacement lead screw 8 to rotate, causing the first carrier plate 2 to move rightward along the limiting rod 9 and pushing the second carrier plate 3 to slide rightward to transport the battery module that has completed the test to the right. When the first carrier plate 2 moves to the rightmost side, the test base 1 no longer supports the second carrier plate 3, causing the second carrier plate 3 to swing downward to an inclined state, that is, to be lapped on the collection frame 7, enabling the battery module to smoothly fall into the collection frame 7. When the first carrier plate 2 resets and moves leftward, it will pull the second carrier plate 3 to the horizontal state for the next test.
