Description

Technical Field

[0001] The present invention relates to the technical field of battery testing, and particularly to a battery testing device for new energy vehicles. Background Art

[0002] As a key component in the new energy field, the performance and safety of pouch batteries directly affect the user experience and reliability of various electronic devices and electric vehicles. Therefore, it is crucial to conduct comprehensive and rigorous testing on pouch batteries.

[0003] Safety performance testing is an important link to ensure the safe use of pouch batteries. The main test items include overcharge test, over-discharge test, short-circuit test, extrusion test, puncture test, and thermal shock test. These tests simulate various extreme situations and abuse conditions to evaluate the reaction and safety performance of the battery under abnormal conditions. For example, the overcharge test evaluates the performance of the battery when the charging voltage exceeds the upper limit; the short-circuit test simulates an accidental short-circuit situation; the extrusion and puncture tests evaluate the safety of the battery when it is physically damaged.

[0004] Among them, the puncture test is an internal short-circuit test method, which is a safety test for testing the internal short-circuit tolerance of lithium-ion batteries. It is to penetrate the battery with a steel nail to simulate an internal short-circuit and confirm whether the battery smokes, catches fire, or ruptures.

[0005] However, in the existing battery testing devices for new energy vehicles, only one battery can be subjected to a puncture experiment at a time, and due to the different sizes of the battery cores, it is necessary to manually adjust the position of the puncture needle, resulting in problems such as low testing efficiency and easy occurrence of missed inspections in the device.

When the first support plate rotates to just below the puncture needle, the battery on the support plate can be punctured for testing. The second support plate is used to remove the punctured battery. The third support plate is used to place the battery to be tested on an empty support plate. This cycle is repeated to improve the detection efficiency.

[0016] Furthermore, the movable component includes a plurality of pillars fixed on the upper surface of the first base plate, an operating panel is fixed on one side of the plurality of pillars away from the first base plate, the long side direction of the operating panel is parallel to the long side direction of the first base plate, two left circular holes and right circular holes which are arranged opposite to each other and have the same diameter are penetrated on the operating panel, a connecting hole located between the left circular hole and the right circular hole is also penetrated on the operating panel, the left circular hole and the right circular hole are connected to each other through the connecting hole, axial columns are arranged in the left circular hole and the right circular hole, the center lines of the two columns coincide with the center lines of the left circular hole and the right circular hole respectively, the bottom of the column is fixed to the left bottom, and the top is flush with the upper surface of the operating panel, and the operating panel, the column, the left circular hole and the right circular hole form a movable slide groove.

A fifth motor for driving the second screw rod to rotate is fixed on the first bottom plate.

[0025] Through the above technical solution, power is provided by the fifth motor to drive the second screw rod fixedly connected with the output shaft of the fifth motor to rotate. The rotation of the second screw rod will drive the second movable block threadedly connected with the second screw rod to slide in the guiding groove. When the supporting rod moves in the vertical groove of the guiding groove, it drives the arc-shaped block and the movable sleeve which are of an integrated structure with the supporting rod to move in the vertical direction. When the supporting rod moves into the horizontal groove of the guiding groove, it drives the arc-shaped block and the movable sleeve which are of an integrated structure with the supporting rod to rotate in the horizontal direction, realizing the rotation of the protective cover and facilitating the exposure of the supporting plate.

[0041] The technical solution of the present invention will be described more clearly and completely below by combining the drawings and describing the preferred implementation modes of the present invention.

[0042] As Figures 1-9 shown, a battery testing device for a new energy vehicle according to a preferred implementation mode of the present invention includes a first bottom plate 1 and a vertical frame 2 provided on one side of the first bottom plate 1. A support plate 3 for supporting the battery is provided above the first bottom plate 1. A plurality of grooves are uniformly formed on the upper surface of the support plate 3 along the long side direction. The plurality of grooves are adapted to the battery and are applicable to batteries of different sizes. A plurality of puncture needles 4 are provided on the side of the vertical frame 2 facing the support plate 3. The puncture needles 4 are connected to the vertical frame 2 through a lateral adjustment assembly 5. A plurality of batteries are uniformly placed on the support plate 3. The position of the puncture needles 4 is adjusted through the lateral adjustment assembly 5 so that the puncture needles 4 correspond to the batteries one by one, facilitating the insertion of the puncture needles 4 into the batteries to perform needle puncture tests on the batteries and evaluate the safety of the batteries when they are physically damaged.

[0043] As Figure 1 and Figure 3 and Figure 4, the horizontal adjustment component 5 includes a mounting plate 501 provided on the vertical frame 2. A first slide rail 502 is fixed to the side of the mounting plate 501 facing away from the vertical frame 2. Four first sliders 503 are slidably connected to the first slide rail 502. An extension plate 504 is fixed to the side of each first slider 503 facing away from the first slide rail 502. The bottom of the extension plate 504 is fixed to the puncture needle 4. The tops of the four first sliders 503 are fixed by a connecting bar 505. Two supports 506 are fixed to the upper surface of the mounting plate 501. A first screw rod 507 is rotatably connected between the two supports 506. A first movable block 508 threadedly connected to the first screw rod 507 is sleeved outside the first screw rod 507. The first movable block 508 is fixed to the connecting bar 505 through a connecting plate 509. A first motor for driving the first screw rod 507 to rotate is fixed to one of the supports 506. A vertical adjustment component 6 for controlling the vertical movement of the mounting plate 501 is provided on the vertical frame 2.

[0044] As Figure 1 and Figure 3 and Figure 4 , power is provided by the first motor to drive the rotation of the first screw rod 507 coaxially fixed to the output shaft of the first motor, thereby driving the movement of the first movable block 508 threadedly connected to the first screw rod 507. The movement of the first movable block 508 will drive the connecting plate 509, the connecting bar 505 and the first slider 503 which are of an integral structure with the first movable block 508 to move. The first slide rail 502 guides the movement of the first slider 503. Power is provided by the vertical adjustment component 6 to drive the mounting plate 501 and the puncture needle 4 on the mounting plate 501 to move in the vertical direction, so as to facilitate piercing into or removing from the battery.

[0045] As Figure 1 and Figure 3 and Figure 4 , the vertical adjustment component 6 includes a circular hole A 601 penetrating the vertical frame 2. An A gear 602 coaxially arranged with the circular hole A 601 is provided in the circular hole A 601. The A gear 602 extends out of the vertical frame 2 through the circular hole A 601. A second motor 603 for driving the A gear 602 to rotate is fixed to the vertical frame 2. An axial A rack 604 is fixed to the side of the mounting plate 501 facing away from the first slide rail 502. The A rack 604 meshes with the A gear 602 extending out of the vertical frame 2. Two second slide rails 605 arranged oppositely are fixed to the vertical frame 2. A second slider 606 is slidably connected to each second slide rail 605. The side of the second slider 606 facing away from the second slide rail 605 is fixed to the mounting plate 501.

[0046] As Figure 1 and Figure 3 and Figure 4, it is powered by the second motor 603 to drive the rotation of the A gear 602 coaxially fixed to the output shaft of the second motor 603. The rotation of the A gear 602 drives the A rack 604 meshing with the A gear 602 to move vertically. Through the cooperation of the second slide rail 605 and the second slider 606, it plays a guiding role in the vertical movement of the mounting plate 501.

[0047] As Figure 2 and Figure 3 and Figure 4 , a B circular hole 7 is opened at the bottom of the vertical frame 2. A B gear 8 coaxially arranged with the B circular hole 7 is arranged in the B circular hole 7. The B gear 8 extends out of the vertical frame 2 through the B circular hole 7. A third motor 9 for driving the rotation of the B gear 8 is fixed on the vertical frame 2. A second bottom plate is arranged below the vertical frame 2, and a B rack 10 meshing with the B gear 8 is fixed on the upper surface of the second bottom plate. Third slide rails 11 are fixed on the front and rear sides of the upper surface of the second bottom plate. A third slider 12 is slidably connected to the third slide rail 11. The side of the third slider 12 facing away from the third slide rail 11 is fixed to the lower surface of the vertical frame 2.

[0048] As Figure 2 and Figure 3 and Figure 4 , it is powered by the third motor 9 to drive the rotation of the B gear 8 coaxially fixed to the output shaft of the third motor 9. The rotation of the B gear 8 drives the B rack 10 meshing with the B gear 8 to move horizontally. Through the cooperation of the third slide rail 11 and the third slider 12, it plays a guiding role in the horizontal movement of the vertical frame 2.

[0049] As Figure 1 and Figure 2 and Figure 5 and Figure 6 , there are three support plates 3. The first bottom plate 1 is connected to the three support plates 3 through the movable assembly 13. Through the power provided by the movable assembly 13, the three support plates 3 are driven to rotate. When the first support plate 3 rotates to directly below the puncture needle 4, it is convenient for the battery on this support plate 3 to be punctured for testing. The second support plate 3 is used to remove the punctured battery, and the third support plate 3 is used to place the battery to be detected on the empty support plate 3. This process is repeated to improve the detection efficiency.

[0050] As Figure 1 and Figure 2 and Figure 5 and Figure 6, the movable component 13 includes several struts fixed on the upper surface of the first bottom plate 1. On the side of the several struts away from the first bottom plate 1, an operation plate 1301 is fixed. The long side direction of the operation plate 1301 is parallel to the long side direction of the first bottom plate 1. Two relatively arranged and identically-diameter left circular holes 1302 and right circular holes 1303 penetrate through the operation plate 1301. A connection hole 1304 located between the left circular hole 1302 and the right circular hole 1303 also penetrates through the operation plate 1301. The left circular hole 1302 and the right circular hole 1303 communicate with each other through the connection hole 1304. Axial columns 1305 are arranged in both the left circular hole 1302 and the right circular hole 1303. The center lines of the two columns 1305 coincide with the center lines of the left circular hole 1302 and the right circular hole 1303 respectively. The bottom of the column 1305 is fixed to the left bottom, and the top is flush with the upper surface of the operation plate 1301. The operation plate 1301, the column 1305, the left circular hole 1302, and the right circular hole 1303 form a movable chute.

[0051] As Figure 1 and Figure 2 and Figure 5 and Figure 6 , the struts are fixedly connected to the left bottom and the operation plate 1301. The two columns 1305 are relatively arranged and located in the left circular hole 1302 and the right circular hole 1303. The operation plate 1301, the column 1305, the left circular hole 1302, and the right circular hole 1303 form a movable chute, facilitating the movement of the three support plates 3.

[0052] As Figure 1 and Figure 2 and Figure 5 and Figure 6, on the circumferential outer walls of the two columns 1305, a left annular gear 1306 and a right annular gear 1307 coaxially arranged with the columns 1305 are respectively nested. The left annular gear 1306 and the right annular gear 1307 are both rotatably connected to the adjacent columns 1305. The left annular gear 1306 and the right annular gear 1307 are meshed with each other and are located between the first bottom plate 1 and the operation plate 1301. Three left arc-shaped grooves 1308 are evenly formed on the left annular gear 1306, and three right arc-shaped grooves 1309 are evenly formed on the right annular gear 1307. At the middle position of the lower surface of the support plate 3, an axial short shaft 1310 is fixed. At the bottom of the short shaft 1310, a cylindrical block 1311 is rotatably connected. The cylindrical block 1311 extends into the left arc-shaped groove 1308 or the right arc-shaped groove 1309 and is adapted to the left arc-shaped groove 1308 or the right arc-shaped groove 1309. On the short shaft 1310, a drop prevention plate 1312 located above the left annular gear 1306 and the right annular gear 1307 is fixed. The size of the drop prevention plate 1312 is larger than the size of the left arc-shaped groove 1308 or the right arc-shaped groove 1309. On the short shaft 1310, a guide plate 1313 with a rhombic cross-section located in the movable chute is also fixed. The size of the guide plate 1313 is adapted to the size of the movable chute. On the upper surface of the first bottom plate 1, a rear gear 1314 located beside the left annular gear 1306 is rotatably connected. The rear gear 1314 meshes with the left gear. On the first bottom plate 1, a fourth motor for driving the rear gear 1314 to rotate is fixed.

[0053] As Figure 1 and Figure 2 and Figure 5 and Figure 6 , powered by the fourth motor, the rear gear 1314 coaxially fixed to the output shaft of the fourth motor is driven to rotate. The rotation of the rear gear 1314 drives the left annular gear 1306 meshing with the rear gear 1314 to rotate. The rotation of the left annular gear 1306 drives the right annular gear 1307 meshing with the left annular gear 1306 to rotate, thereby driving the cylindrical block 1311 in the left arc-shaped groove 1308 and the right arc-shaped groove 1309 to rotate. The rotation of the cylindrical block 1311 drives the short shaft 1310 rotatably connected to the cylindrical block 1311 to rotate, thereby driving the guide plate 1313 fixed to the short shaft 1310 to move in the movable chute, so as to facilitate the transformation of the positions of the three support plates 3. The left annular gear 1306 and the right annular gear 1307, and the left arc-shaped groove 1308 and the right arc-shaped groove 1309 have the same size.

[0054] As Figure 1 and Figure 7 and Figure 8 and Figure 9, a protective cover 14 is provided on the operation panel 1301 beside the puncture needle 4. A moving component 15 for controlling the rotation of the protective cover 14 is provided on the first bottom plate 1. The protective cover 14 is made of a transparent material and its surface is coated with a fireproof material. Driven by the moving component 15, the protective cover 14 moves. When the protective cover 14 moves to the operation panel 1301 and is located outside the puncture needle 4, the possibility of the battery puncturing and catching fire to endanger the staff or the batteries on other support plates 3 is reduced, and the safety of the device is improved.

[0055] Such as Figure 1 And Figure 7 And Figure 8 And Figure 9 , the moving component 15 includes a fixing plate 1501 fixedly connected to the first bottom plate 1. A main guiding sleeve 1502 is fixed on the fixing plate 1501. A moving sleeve 1503 is sleeved outside the main guiding sleeve 1502. A connecting rod 1504 is radially fixed on the circumferential outer wall of the moving sleeve 1503. One end of the connecting rod 1504 far from the moving sleeve 1503 is fixed with a secondary guiding sleeve 1505. A moving column 1506 is slidably connected inside the secondary guiding sleeve 1505. Both ends of the moving column 1506 penetrate out of the secondary guiding sleeve 1505. The bottom end of the moving column 1506 penetrating out of the secondary guiding sleeve 1505 is fixed to the protective cover 14, and an anti - detachment plate 1507 is fixed at the top. The protective cover 14 and the secondary guiding sleeve 1505 are fixedly connected by a spring 1508. The movement of the moving sleeve 1503 will drive the connecting rod 1504 and the secondary guiding sleeve 1505 which are of an integral structure with the moving sleeve 1503 to move, and further drive the moving column 1506 arranged inside the secondary guiding sleeve 1505 to move.

[0056] Such as Figure 1 And Figure 7 And Figure 8 And Figure 9 , a guiding groove 1509 with an inverted L - shaped cross - section is formed on the main guiding sleeve 1502. A second screw rod 1510 coaxial with the main guiding sleeve 1502 is arranged inside the main guiding sleeve 1502. The second screw rod 1510 is rotatably connected to the main guiding sleeve 1502. A second moving block 1511 threadedly connected to the second screw rod 1510 is sleeved outside the second screw rod 1510. The second moving block 1511 is located between the second screw rod 1510 and the main guiding sleeve 1502. A support rod 1512 is fixed on the circumferential outer wall of the second moving block 1511. The support rod 1512 is located inside the guiding groove 1509 and is slidably connected to the guiding groove 1509. One end of the support rod 1512 far from the second moving block 1511 extends out of the main guiding sleeve 1502 through the guiding groove 1509. One end of the support rod 1512 extending out of the main guiding sleeve 1502 is fixed with an arc - shaped block 1513 adapted to the main guiding sleeve 1502. The arc - shaped block 1513 is fixed to the moving sleeve 1503. A fifth motor for driving the second screw rod 1510 to rotate is fixed on the first bottom plate 1.

[0057] As Figure 1 and Figure 7 and Figure 8 and Figure 9 , it is powered by the fifth motor to drive the rotation of the second screw rod 1510 coaxially fixed to the output shaft of the fifth motor. The rotation of the second screw rod 1510 drives the second movable block 1511 threadedly connected to the second screw rod 1510 to slide in the guide groove 1509. When the support rod 1512 moves in the vertical groove of the guide groove 1509, it drives the arc-shaped block 1513 and the movable sleeve 1503, which are of an integral structure with the support rod 1512, to move in the vertical direction. When the support rod 1512 moves into the horizontal groove of the guide groove 1509, it drives the arc-shaped block 1513 and the movable sleeve 1503, which are of an integral structure with the support rod 1512, to rotate in the horizontal direction, realizing the rotation of the protective cover 14 and facilitating the exposure of the support plate 3.

[0058] During use, turn on the fourth motor. It is powered by the fourth motor to drive the rotation of the rear gear 1314 coaxially fixed to the output shaft of the fourth motor. The rotation of the rear gear 1314 drives the rotation of the left annular gear 1306 meshing with the rear gear 1314. The rotation of the left annular gear 1306 drives the rotation of the right annular gear 1307 meshing with the left annular gear 1306, thereby driving the movement of the cylindrical block 1311 in the left arc-shaped groove 1308 and the right arc-shaped groove 1309. The rotation of the cylindrical block 1311 drives the movement of the short shaft 1310 rotatably connected to the cylindrical block 1311, thereby driving the movement of the guide plate 1313 fixed to the short shaft 1310 in the movable chute. When the guide plate 1313 moves with the left annular gear 1306 to the position between the left circular hole 1302 and the right circular hole 1303, the guide plate 1313 is restricted by the movable chute and enters the gap between the right circular hole 1303 and the column 1305. And the cylindrical block 1311 enters the right arc-shaped groove 1309 of the right annular gear 1307 as the guide plate 1313 moves, so that the cylindrical block 1311 can move as the right annular gear 1307 rotates. When the guide plate 1313 moves with the right annular gear 1307 to the position between the left circular hole 1302 and the right circular hole 1303, the guide plate 1313 is also restricted by the movable chute and enters the gap between the left circular hole 1302 and the column 1305. And the cylindrical block 1311 enters the left arc-shaped groove 1308 of the left annular gear 1306 as the guide plate 1313 moves, so that the cylindrical block 1311 can move as the right annular gear 1307 rotates. The movement of the short shaft 1310 drives the movement of the support plate 3 fixed to the short shaft 1310, facilitating the transformation of the positions of the three support plates 3;

[0059] The first support plate 3 is moved below the puncture needle 4. After reaching the working position, the fourth motor is shut down. The battery to be detected is placed on the second support plate 3 that is about to enter the right circular hole 1303 by the staff, and another staff member takes out the battery that has been detected from the third support plate 3 that moves into the left circular hole 1302, saving the feeding and discharging time and improving the puncture detection efficiency;

[0060] Meanwhile, the third motor 9 is turned on. Driven by the power provided by the third motor 9, the B gear 8 coaxially fixed to the output shaft of the third motor 9 rotates. The rotation of the B gear 8 drives the B rack 10 meshing with the B gear 8 to move horizontally. Through the cooperation of the third slide rail 11 and the third slider 12, it plays a guiding role in the horizontal movement of the gantry 2. The gantry 2 moves towards the direction of the first bottom plate 1 and approaches the first support plate 3;

[0061] After that, the first motor is turned on. Driven by the power provided by the first motor, the first screw rod 507 coaxially fixed to the output shaft of the first motor rotates, thereby driving the first movable block 508 threadedly connected to the first screw rod 507 to move. The movement of the first movable block 508 drives the connecting plate 509, the connecting strip 505 and the first slider 503 of the integral structure with the first movable block 508 to move. Through the first slide rail 502, it plays a guiding role in the movement of the first slider 503, making the four puncture needles 4 correspond to the batteries on the first support plate 3 one by one, which is applicable to batteries of different sizes;

[0062] The second motor 603 is turned on. Driven by the power provided by the second motor 603, the A gear 602 coaxially fixed to the output shaft of the second motor 603 rotates. The rotation of the A gear 602 drives the A rack 604 meshing with the A gear 602 to move vertically. The movement of the A rack 604 drives the mounting plate 501 fixed to the A rack 604 to move, thereby adjusting the vertical positions of the four puncture needles 4, making the puncture needles 4 insert into the battery to perform a puncture test on the battery. Through the cooperation of the second slide rail 605 and the second slider 606, it plays a guiding role in the vertical movement of the mounting plate 501;

[0063] Before performing the puncture test, the staff also need to turn on the fifth motor. The fifth motor provides power to drive the rotation of the second screw rod 1510 fixed coaxially with the output shaft of the fifth motor. The rotation of the second screw rod 1510 drives the second movable block 1511 threadedly connected to the second screw rod 1510 to slide within the guide groove 1509. The initial position of the support rod 1512 is within the transverse groove of the guide groove 1509. When the support rod 1512 moves within the transverse groove of the guide groove 1509, it drives the arc-shaped block 1513 and the movable sleeve 1503, which are of an integrated structure with the support rod 1512, to rotate horizontally, causing the protective cover 14 to rotate above the first support plate 3. When the support rod 1512 rotates into the vertical groove within the guide groove 1509, it drives the arc-shaped block 1513 and the movable sleeve 1503, which are of an integrated structure with the support rod 1512, to move vertically downward, driving the protective cover 14 to move downward until it abuts against the upper surface of the operation plate 1301, protecting the first support plate 3 and reducing the possibility of fire during the battery puncture test from damaging the staff or other electrical appliances, thereby improving the safety of the device;

[0064] After the puncture test is completed, reverse the rotation of the second screw rod 1510 to drive the protective cover 14 to move upward and rotate outside the operation plate 1301. Turn on the second motor 603 to drive the A gear 602 to reverse, causing the puncture needle 4 to move upward above the battery. Turn on the third motor 9 to drive the B gear 8 to reverse, causing the upright frame 2 to move away from the operation plate 1301, without affecting the rotation of the support plate 3. Then turn on the fourth motor to cause the rear gear 1314 to continue rotating, realizing the replacement of the three support plates 3 and improving the test efficiency.
