DETAILED DESCRIPTION

[0031] The present invention is further described below with reference to the accompanying drawings, and embodiments of the present invention are given below with reference to the accompanying drawings.

[0032] Example 1

[0033] A lithium-ion battery power release performance detection device includes a base frame 1, a servo motor 2, a conductive frame 21, a U-shaped insulating frame 3, a conductive mechanism 4 and a discharge mechanism 5. Figure 1-Figure 5 As shown, a U-shaped insulating frame 3 is installed between the four ends of the top of the base frame 1 by welding, and a conductive frame 21 is symmetrically fixed to the middle of the lower part of the outer front side of the U-shaped insulating frame 3. The servo motor 2 is fixed between the inner sides of the left and right conductive frames 21. The left and right conductive frames 21 are respectively in contact with the positive and negative poles of the servo motor 2. A conductive mechanism 4 is installed on the front side of the top of the U-shaped insulating frame 3. When the conductive mechanism 4 is in contact with the positive and negative poles of the lithium-ion motor, the conductive mechanism 4 is used to guide the current. A discharge mechanism 5 is installed between the conductive mechanism 4 and the two conductive frames 21. The discharge mechanism 5 is used to guide the current into the conductive frame 21.

[0034] The conductive mechanism 4 includes a clamping block 41, a sliding frame 42, a vertical shaft 43, a torsion spring 44, a first spring 45, a horizontal plate 46 and a rubber sleeve 47. Figure 1 、 Figure 3 and Figure 4 As shown, a horizontal plate 46 is installed on the top of the front side of the U-shaped insulating frame 3 by welding, and the horizontal plate 46 is symmetrically and slidingly connected with the sliding frame 42 on the left and right sides. A first spring 45 is connected between the front side surfaces of the inner front sides of the left and right sliding frames 42 and the front side surfaces of the horizontal plate 46. The rear sides of the left and right sliding frames 42 are fixedly connected with vertical shafts 43, and two clamping blocks 41 are rotatably connected to the left and right vertical shafts 43. The clamping blocks 41 are used to clamp the positive and negative poles of the lithium-ion battery. A torsion spring 44 is connected between the inner middle parts of the two clamping blocks 41 on the left and between the inner middle parts of the two clamping blocks 41 on the right. The torsion spring 44 is sleeved on the vertical shaft 43, and the front ends of the four clamping blocks 41 are fixed with rubber sleeves 47.

[0035] The discharge mechanism 5 includes a limit plate 51, an L-shaped rubber frame 52, a telescopic rod 54 and a connecting frame 55. Figure 1 and Figure 5As shown, a connecting frame 55 is fixed between the two ends of the top of the left conductive frame 21, and a connecting frame 55 is also fixed between the two ends of the top of the right conductive frame 21. The front sides of the two sliding frames 42 are installed with limit plates 51 by welding. An L-shaped rubber frame 52 is fixed between the front side surfaces of the left and right limit plates 51. The middle of the bottom of the left and right limit plates 51 are rotatably connected with a telescopic rod 54. The lower parts of the left and right telescopic rods 54 are rotatably connected to the rear sides of the tops of the left and right connecting frames 55 respectively. When current is introduced into the telescopic rod 54, the telescopic rod 54 can introduce the current into the connecting frame 55.

[0036] Also includes a rubber grip 53, see Figure 5 As shown, a rubber gripping rod 53 is fixedly mounted on the middle of the upper portion of the L-shaped rubber frame 52 .

[0037] First, the operator puts the lithium-ion battery into the U-shaped insulating frame 3, and then pushes the discharge mechanism 5 to move backward. The discharge mechanism 5 moves backward and drives the conductive mechanism 4 to move backward. When the conductive mechanism 4 moves backward and contacts the positive and negative poles of the lithium-ion battery, the conductive mechanism 4 clamps on the positive and negative poles of the lithium-ion battery, releases the discharge mechanism 5, and the discharge mechanism 5 stops driving the conductive mechanism 4 to move backward. The lithium-ion battery introduces current into the conductive mechanism 4, and the current in the conductive mechanism 4 is introduced into the discharge mechanism 5. The current in the discharge mechanism 5 is introduced into the conductive frame 21, and the current in the conductive frame 21 is introduced into the servo motor 2. The current drives the servo motor 2 to rotate, and the operator can check the rotation of the servo motor 2. If the servo motor 2 rotates smoothly all the time, This means that there is no problem with the power release of the lithium-ion battery. On the contrary, if the rotation of the servo motor 2 is intermittent, it means that there is a problem with the power release of the lithium-ion battery. After the power release performance test of the lithium-ion battery is completed, the conductive mechanism 4 is pulled out of contact with the positive and negative poles of the lithium-ion battery, and the current stops being introduced into the conductive mechanism 4. The conductive mechanism 4 stops introducing the current into the discharge mechanism 5, and the discharge mechanism 5 also stops introducing the current into the servo motor 2 through the conductive frame 21. The servo motor 2 stops rotating, and then the discharge mechanism 5 is pulled to drive the conductive mechanism 4 to move forward and reset. The conductive mechanism 4 is released, and the lithium-ion battery can be removed from the U-shaped insulating frame 3. This can be repeated to continuously test the power release performance of the lithium-ion battery.

[0038] When the lithium-ion battery is placed in the U-shaped insulating frame 3, the discharge mechanism 5 is pushed to move backward, and the discharge mechanism 5 moves backward to drive the sliding frame 42 to move backward. The first spring 45 is compressed, and the sliding frame 42 moves backward to drive the vertical shaft 43 to move backward. The vertical shaft 43 moves backward to drive the clamping block 41 to move backward. When the clamping block 41 moves backward and contacts the positive and negative poles of the lithium-ion battery, the positive and negative poles of the lithium-ion battery drive the clamping block 41 to swing. The torsion spring 44 is compressed, and the clamping block 41 moves backward so that the inner side contacts the positive and negative poles of the lithium-ion battery. Due to the action of the torsion spring 44, the two clamping blocks on the left and right sides 41 moves inward and clamps on the positive and negative poles of the lithium-ion battery respectively, stops pushing the discharge mechanism 5, and the discharge mechanism 5 stops driving the left and right sliding frames 42 to move backward. The left and right sliding frames 42 stop driving the clamping block 41 to move backward through the vertical shaft 43. The lithium-ion battery then introduces current into the clamping block 41, and the current in the clamping block 41 is introduced into the sliding frame 42 through the vertical shaft 43. The current in the sliding frame 42 is introduced into the discharge mechanism 5, which makes the current drive the servo motor 2 to rotate. By checking the rotation of the output shaft of the servo motor 2, it can be understood whether the power release performance of the lithium-ion battery is qualified. When the power release performance test of the lithium-ion battery is completed, the rubber sleeve 47 is pressed to swing inward. The inward swing of the rubber sleeve 47 drives the clamping block 41 to swing out of contact with the positive and negative poles of the lithium-ion battery. The lithium-ion battery stops introducing current into the clamping block 41, and no current is introduced into the discharge mechanism 5. The servo motor 2 stops rotating, and the rubber sleeve 47 is loosened. Due to the action of the first spring 45, the sliding frame 42 moves forward and resets, and drives the clamping block 41 to move forward and reset through the vertical shaft 43. The rubber sleeve 47 is loosened, and due to the action of the torsion spring 44, the clamping block 41 swings and resets.

[0039] When the lithium-ion battery is placed in the U-shaped insulating frame 3, the L-shaped rubber frame 52 is pushed to move backward. Due to the action of the rubber grip 53, the friction with the hand is increased, allowing the operator to push the L-shaped rubber frame 52 more firmly. The backward movement of the L-shaped rubber frame 52 drives the left and right limit plates 51 to move backward. The backward movement of the left and right limit plates 51 drives the left and right sliding frames 42 to move backward. The first spring 45 is compressed, which makes the clamping block 41 move backward and contact the positive and negative poles of the lithium-ion battery. At the same time, the backward movement of the left and right limit plates 51 also drives the left and right telescopic rods 54 to swing backward and extend. When the clamping block 41 is clamped on the positive and negative poles of the lithium-ion battery, the pushing of the L-shaped rubber frame 52 is stopped. The right side limit plates 51 stop driving the left and right side sliding frames 42 to move backward, and the clamping block 41 also stops moving backward. At the same time, the left and right side limit plates 51 stop driving the left and right side telescopic rods 54 to swing and extend backward. When the lithium-ion battery introduces current into the clamping block 41, the current in the sliding frame 42 is introduced into the limit plates 51, the current in the limit plates 51 is introduced into the telescopic rod 54, the current in the telescopic rod 54 is introduced into the connecting frame 55, the current in the connecting frame 55 is introduced into the conductive frame 21, and the current in the conductive frame 21 is introduced into the servo motor 2. The current also drives the servo motor 2 to rotate. The operator can check the rotation of the output shaft of the servo motor 2 to understand whether the power release performance of the lithium-ion battery is qualified. When the power release performance test of the lithium-ion battery is completed, the rubber sleeve 47 is pressed to drive the clamping block 41 to disengage from the positive and negative poles of the lithium-ion battery. Due to the action of the first spring 45, the left and right sliding frames 42 move forward and reset, driving the left and right limit plates 51 to move forward and reset. The left and right limit plates 51 move forward and reset, driving the L-shaped rubber frames 52 to move forward and reset. The left and right limit plates 51 also drive the left and right telescopic rods 54 to swing forward and reset to shorten. The current stops being introduced into the clamping block 41, and the current in the sliding frame 42 also stops being introduced into the limit plate 51. The limit plate 51 also stops introducing current into the telescopic rod 54. The telescopic rod 54 stops introducing current into the connecting frame 55. The connecting frame 55 stops introducing current into the conductive frame 21, and the servo motor 2 stops rotating.

[0040] Example 2

[0041] On the basis of embodiment 1, a prompt mechanism 6 is further included. The prompt mechanism 6 includes a limit frame 61, a guide ring 62, a rotating magnetic ring 63, a rotating frame 64, a second spring 65, a magnet 66 and a marking block 67. Figure 1 and Figure 6As shown, a limit frame 61 is installed in the middle of the left bottom of the base frame 1 by bolt connection, and a guide ring 62 is fixed between the two ends of the front side of the limit frame 61. A rotating magnetic ring 63 is connected to the inner side of the guide ring 62 in a circumferentially rotatable manner. When the rotating magnetic ring 63 rotates, the rotating magnetic ring 63 can prompt people about the rotation status of the servo motor 2. A marking block 67 is fixed at an eccentric position on the left side of the rotating magnetic ring 63. A rotating frame 64 is fixedly mounted on the left side of the output shaft of the servo motor 2. Magnets 66 are slidably mounted on the four sides of the rotating frame 64. When the magnet 66 moves outward and contacts the rotating magnetic ring 63, the magnet 66 can drive the rotating magnetic ring 63 to rotate forward. A second spring 65 is connected between the inner sides of the four magnets 66 and the inner side of the rotating frame 64.

[0042] The protective mechanism 7 includes a transmission assembly 71, a rotating shaft 72, a one-way clutch 73, a volute spring 74, a column gear 75 and a grounding frame 76. Figure 1 、 Figure 7 、 Figure 8 and Figure 9 As shown, there are two rotating shafts 72 connected in a rotating manner in the middle of the outer bottom of the U-shaped insulating frame 3. The two rotating shafts 72 are symmetrically arranged front to back. Two grounding frames 76 are fixedly mounted on the front and rear rotating shafts 72. When the grounding frames 76 swing downward and contact the ground, the grounding frames 76 can realize the conduction of current into the ground. The two grounding frames 76 are electrically connected to the conductive frame 21. A column gear 75 is fixedly mounted on the right side of the two rotating shafts 72. The two column gears 75 are meshed. A one-way clutch 73 is fixedly connected to the left side of the front rotating shaft 72. A transmission assembly 71 is connected between the outer side of the one-way clutch 73 and the right side of the rotating magnetic ring 63. The transmission assembly 71 consists of a large pulley, a small pulley and a flat belt. The small pulley is fixedly mounted on the outer side of the one-way clutch 73. The large pulley is fixed to the right side of the rotating magnetic ring 63. The flat belt is wound between the large pulley and the small pulley. A volute spring 74 is connected between the output shaft of the servo motor 2 and the center position of the front circle of the transmission assembly 71.

[0043] When the servo motor 2 is started, it also drives the rotating frame 64 in forward rotation. This forward rotation of the rotating frame 64 also drives the magnet 66 in forward rotation. Due to centrifugal force, the magnet 66 moves outward while rotating forward, and the second spring 65 is stretched. When the magnet 66 moves outward and contacts the rotating magnetic ring 63, the forward rotation of the magnet 66 drives the rotating magnetic ring 63 in forward rotation. The forward rotation of the rotating magnetic ring 63 drives the indicator block 67 in forward rotation. The operator can observe the rotation of the rotating magnetic ring 63 to determine whether the lithium-ion power release performance is qualified. The indicator block 67 allows the operator to more clearly understand the rotation of the rotating magnetic ring 63. After the lithium-ion battery power release performance test is completed, the clamping block 41 is separated from the positive and negative terminals of the lithium-ion battery. The servo motor 2 stops driving the rotating frame 64 in forward rotation, and the rotating frame 64 stops driving the magnet 66 in forward rotation. The magnet 66 stops driving the rotating magnetic ring 63 in forward rotation. The second spring 65 causes the magnet 66 to move inward and reset. This allows the operator to more intuitively determine whether the lithium-ion battery power release performance is qualified.

[0044] When the servo motor 2 rotates forward, the servo motor 2 drives the rotating frame 64 to rotate forward. At the same time, the servo motor 2 first drives the volute spring 74 to compress a certain stroke. Then, when the magnet 66 contacts the rotating magnetic ring 63, the magnet 66 drives the rotating magnetic ring 63 to rotate forward. The forward rotation of the rotating magnetic ring 63 drives the transmission component 71 to rotate forward. The forward rotation of the transmission component 71 drives the one-way clutch 73 to rotate forward. The forward rotation of the one-way clutch 73 will not drive the front side rotating shaft 72 to rotate forward. When the power release performance test of the lithium-ion battery is completed, the power of the lithium-ion battery is not enough to drive the servo motor 2 to rotate, but there will still be current in the conductive frame 21. The servo motor 2 stops driving the rotating frame 64 to rotate forward, the magnet 66 disengages from the rotating magnetic ring 63, and the rotating magnetic ring 63 stops driving the transmission component 71 to rotate forward. Due to the action of the volute spring 74, the transmission component 71 reverses and drives the one-way clutch 73 to reverse. The reverse rotation of the one-way clutch 73 drives the front rotating shaft 72 to reverse. The front shaft 72 rotates in reverse, driving the two front grounding frames 76 to swing downward and contact the ground. The front shaft 72 rotates in reverse, driving the front column gear 75 to rotate in reverse. The front column gear 75 rotates in reverse, driving the rear column gear 75 to rotate forward. The rear column gear 75 rotates forward, driving the rear shaft 72 to rotate forward. The rear shaft 72 rotates forward, driving the two rear grounding frames 76 to swing downward, and the two rear grounding frames 76 swing downward and contact the ground. The four grounding frames 76 also play a grounding role, avoiding leakage and endangering personal safety. The operator can remove the tested lithium-ion battery from the U-shaped insulating frame 3, and then pull the four grounding frames 76 to swing upward and reset. The four grounding frames 76 swing upward and reset, driving the two shafts 72 to rotate and reset. The rotation and reset of the two shafts 72 drive the transmission assembly 71 to rotate and reset through the one-way clutch 73. The rotation of the transmission assembly 71 drives the servo motor 2 to rotate a certain distance through the spiral spring 74. In this way, leakage can be avoided to endanger the lives of people around.

[0045] Example 3

[0046] On the basis of embodiment 1 and embodiment 2, a shockproof mechanism 8 is further included. The shockproof mechanism 8 includes a clamping plate 81, a limit spring 82 and a guide rod 83. Figure 1 and Figure 10 As shown, guide rods 83 are symmetrically and slidingly connected to the front and rear sides of the U-shaped insulating frame 3. The inner ends of the four guide rods 83 are installed with clamping plates 81 by welding. When the lithium-ion battery is placed in the U-shaped insulating frame 3, the clamping plate 81 can clamp the lithium-ion battery. The inner sides of the four guide rods 83 are connected to the outer side of the U-shaped insulating frame 3. Limiting springs 82 are connected between the inner sides of the four guide rods 83 and the outer side of the U-shaped insulating frame 3.

[0047] The heat dissipation mechanism 9 includes a mounting plate 91 and a fan 92. Figure 1 and Figure 11 As shown, a mounting plate 91 is fixed between the tops of the left and right conductive frames 21 , and a fan 92 is installed in the middle of the mounting plate 91 . When the fan 92 is started, the fan 92 can discharge the heat emitted by the lithium-ion battery.

[0048] When the operator places the lithium-ion battery into the U-shaped insulating frame 3, it contacts the clamping plate 81, which in turn moves the clamping plate 81 outward. This outward movement of the clamping plate 81 in turn moves the guide rod 83 outward, stretching the limit spring 82 and securing the lithium-ion battery. After the lithium-ion battery power release performance test is complete, the lithium-ion battery is removed from the U-shaped insulating frame 3. The lithium-ion battery disengages from the clamping plate 81, and the limit spring 82 causes the guide rod 83 to move the clamping plate 81 inward and reset. This prevents movement of the lithium-ion battery from affecting the power release performance test.

[0049] When the lithium-ion battery is being tested for power release performance, fan 92 is activated. Fan 92 rotates to dissipate heat generated during the test, thereby removing heat from the vicinity of the lithium-ion battery. When the test is complete, fan 92 is turned off. This prevents excessive temperatures near the lithium-ion battery from affecting the test.

[0050] Finally, it is necessary to point out that the above content is only used to help understand the technical solution of the present invention and cannot be understood as limiting the scope of protection of the present invention; non-essential improvements and adjustments made by technical personnel in this field based on the above content of the present invention are all within the scope of protection required by the present invention.
