During the insertion of the counterweight block 36 into the assembly groove 35, the stop block 38 contacts the first impact block 34 and enters the circular groove 37 to squeeze the first spring 39. The stop block 38 abuts against the inner wall of the assembly groove 35 to improve the stability of the counterweight block 36 after installation.

[0022] A conversion assembly 50 assembled on the first impact block 34, a second impact block 52 arranged on the conversion block 51 included in the conversion assembly 50, changing the impact surface during battery impact detection to adjust the impact detection form, the conversion assembly 50 also includes a rotating rod 53 rotatably mounted in the first impact block 34, the conversion block 51 is fixedly mounted on the rotating rod 53, and the second impact block 52 is fixedly mounted on the conversion block 51; When it is necessary to detect the result of the battery being impacted by a blade-shaped heavy object, when the rotating rod 53 is rotated, the conversion block 51 rotates in the first impact block 34. When the conversion block 51 rotates 180°, the second impact block 52 faces the battery. When performing the impact test, the blade-shaped second impact block 52 can hit the battery to complete the test; It should be noted that the two sides of the conversion block 51 are arranged in an arc shape. When the second impact block 52 faces upward, the lower surface of the first impact block 34 is flush with the conversion block 51 .

[0023] The second impact block 52 is provided with a cavity 54, in which a third impact block 55 is slidably installed, and an elastic member 56 is fixedly installed on the third impact block 55, and the other end of the elastic member 56 is fixedly connected to the inner wall of the cavity 54, and a slider 57 is slidably installed in the cavity 54, and the slider 57 is provided with a chamfer that matches the third impact block 55, and the second impact block 52 is provided with a limiting groove 59, and a shifting block 58 is slidably installed in the limiting groove 59, and the shifting block 58 is fixedly connected to the slider 57; When it is necessary to detect the result of the battery being impacted by a sharp heavy object, slide the shift block 58 in the limit groove 59, and the shift block 58 drives the slider 57 to slide in the cavity 54. During the sliding process of the slider 57, it abuts against the surface of the third impact block 55 and drives the third impact block 55 to slide in the cavity 54 and stretch the elastic member 56. When the slider 57 slides to the specified position, the sharp end of the third impact block 55 is higher than the second impact block 52. During the detection, the third impact block 55 can impact on the battery, thereby detecting the result of the battery being impacted by a sharp heavy object.

[0024] The angle adjustment assembly 20 includes a rotating shaft 21 rotatably mounted on the base 10, the frame 11 is fixedly connected to the rotating shaft 21, an adjusting arc plate 22 is fixedly mounted on the base 10, an arc groove 23 is formed on the adjusting arc plate 22, a pair of positioning rods 24 cooperating with the arc groove 23 are fixedly mounted on the frame 11, a mounting plate 25 is fixedly mounted on the positioning rods 24, a threaded rod 26 is threadedly connected to the mounting plate 25, and a pressing plate 27 is rotatably mounted on the threaded rod 26; In order to test the results of the second impact block 52 and the third impact block 55 impacting the battery from different angles, the frame 11 is rotated with the rotating shaft 21 as the axis. When the frame 11 rotates, the positioning rod 24 slides in the arc groove 23. When the positioning rod 24 reaches a suitable detection angle, the threaded rod 26 is rotated. The threaded rod 26 drives the pressure plate 27 to approach and abut against the adjustment arc plate 22. When the threaded rod 26 is rotated to a suitable position, the frame 11 is fixed. At this time, after the electromagnet 33 is powered off, the first impact block 34 can drive the second impact block 52 or the third impact block 55 to perform an impact test on the battery, thereby improving the diversity of the test and obtaining more detailed test results.

When the hot melt adhesive block 64 is completely melted, the elastic force of the spring drives the protective plate 62 to pop out from the movable groove 61, covering the battery placement area to prevent the battery explosion from causing harm to the observer; It should be noted that the magnetic first impact block 34 can accelerate the ejection of the protective plate 62 and improve the protection efficiency.

When the battery explosion and fire protection plate 62 pops out, the opening 66 loses the blockage of the protection plate 62, and the carbon dioxide in the storage cavity 65 is sprayed out along the movable groove 61 and sprayed toward the battery along the protection plate 62, achieving the effect of timely extinguishing the fire, thereby further improving the safety of the equipment.

[0027] like Fig. 9 As shown, a method for battery impact detection, using the above-mentioned battery impact detection device, includes the following steps: S1. Testing: The battery is placed on the base 10, and then the electromagnet 33 is powered off, and the first impact block 34 falls along the frame 11 under the influence of gravity to perform an impact test on the battery; S2, reset: after impact, the motor 41 cooperates with the driving tooth 42 to drive the sliding tooth plate 31, the connecting plate 32 and the electromagnet 33 to descend. After the electromagnet 33 descends to a suitable position, the electromagnet 33 is energized to attract the first impact block 34. Then the motor 41 reverses and cooperates with the driving tooth 42 to drive the sliding tooth plate 31, the connecting plate 32, the electromagnet 33 and the first impact block 34 to rise and reset; S3. Adjustment: Insert the counterweight block 36 into the assembly groove 35 as needed to adjust the weight of the first impact block 34. During the process of inserting the counterweight block 36 into the assembly groove 35, the stop block 38 contacts the first impact block 34 and enters the circular groove 37 to squeeze the first spring 39, thereby improving the stability of the counterweight block 36 after installation.

[0028] Working principle: Place the battery on the base 10, and then the electromagnet 33 is powered off. The first impact block 34 falls along the frame 11 under the influence of gravity to perform an impact test on the battery. After the impact, the motor 41 cooperates with the driving gear 42 to drive the sliding tooth plate 31, the connecting plate 32 and the electromagnet 33 to descend. After the electromagnet 33 descends to a suitable position, the electromagnet 33 is powered on and adsorbed to the first impact block 34. Then the motor 41 reverses and cooperates with the driving gear 42 to drive the sliding tooth plate 31, the connecting plate 32, the electromagnet 33 and the first impact block 34 to rise to a specified height, waiting for the next impact test. The first impact block 34 can be stopped at different positions, so as to test the impact results of the first impact block 34 at different heights on the battery. Before the test, the weight block 36 can be inserted into the assembly groove 35 as needed to adjust the weight of the first impact block 34, so as to achieve the test of the impact result of the first impact block 34 with different weights on the battery. During the insertion of the weight block 36 into the assembly groove 35, the stop block 38 contacts the first impact block 34 and enters the circular groove 37 to squeeze the first spring 39. The stop block 38 abuts against the inner wall of the assembly groove 35 to improve the stability of the weight block 36 after installation. When it is necessary to detect the result of the battery being impacted by a blade-shaped heavy object, when the rotating rod 53 is rotated, the conversion block 51 rotates in the first impact block 34. When the conversion block 51 rotates 180°, the second impact block 52 faces the battery. When performing the impact test, the blade-shaped second impact block 52 can hit the battery to complete the test; It should be noted that the two sides of the conversion block 51 are arranged in an arc shape, and when the second impact block 52 faces upward, the lower surface of the first impact block 34 is flush with the conversion block 51; When it is necessary to detect the result of the battery being impacted by a sharp heavy object, the shifting block 58 is slid in the limiting groove 59, and the shifting block 58 drives the slider 57 to slide in the cavity 54. During the sliding process of the slider 57, it abuts against the surface of the third impact block 55 and drives the third impact block 55 to slide in the cavity 54 and stretch the elastic member 56. When the slider 57 slides to the specified position, the sharp end of the third impact block 55 is higher than the second impact block 52. During the detection, the third impact block 55 can impact on the battery, thereby detecting the result of the battery being impacted by a sharp heavy object; In order to test the results of the second impact block 52 and the third impact block 55 impacting the battery from different angles, the frame 11 is rotated with the rotating shaft 21 as the axis. When the frame 11 rotates, the positioning rod 24 slides in the arc groove 23. When the positioning rod 24 reaches a suitable detection angle, the threaded rod 26 is rotated, and the threaded rod 26 drives the pressure plate 27 to approach and abut against the adjustment arc plate 22. When the threaded rod 26 is rotated to a suitable position, the frame 11 is fixed. At this time, after the electromagnet 33 is powered off, the first impact block 34 can drive the second impact block 52 or the third impact block 55 to perform an impact test on the battery, thereby improving the diversity of the test. When the battery explodes and catches fire after being hit, the high temperature generated causes the hot melt adhesive block 64 to melt. When the hot melt adhesive block 64 is completely melted, the elastic force of the spring drives the protective plate 62 to pop out from the movable groove 61, covering the battery placement area to prevent the battery explosion from causing harm to the observer; Carbon dioxide gas is filled into the storage cavity 65 before detection. When the battery explosion and fire protection plate 62 pops out, the opening 66 loses the blockage of the protection plate 62, and the carbon dioxide in the storage cavity 65 is sprayed out along the movable groove 61 and sprayed toward the battery along the protection plate 62, achieving the effect of timely extinguishing the fire.
