Description

Technical Field

[0001] This utility model belongs to the field of battery testing technology, specifically a lithium battery life testing device with a detachable battery clamping structure. Background Technology

[0002] In the production and R&D of lithium batteries, accurate testing of battery life is a crucial step. Traditional lithium battery life testing devices typically use a fixed clamping structure to hold the battery. This structure has several significant limitations in practical use. First, the fixed clamping structure cannot be flexibly adjusted according to different battery sizes, requiring frequent clamp changes or device readjustment when testing different models of lithium batteries. This not only increases operational complexity but also reduces testing efficiency. Second, the fixed clamping structure often struggles to ensure uniform clamping force, easily resulting in over-clamping that damages the battery or under-clamping that leads to poor contact, thus affecting the accuracy and reliability of the test. Furthermore, removing the battery from the fixed clamp after testing is inconvenient, further increasing operational time costs. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a lithium battery life testing device with a detachable battery clamping structure. This solves the problem that traditional lithium battery life testing devices usually use a fixed clamping structure to fix the battery, which cannot be flexibly adjusted according to different battery sizes. This results in the need to frequently change the clamps or readjust the device when testing different types of lithium batteries. Secondly, the fixed clamping structure often cannot guarantee the uniformity of clamping force when clamping the battery, which can easily lead to over-clamping and battery damage, or under-clamping and poor contact, thus affecting the accuracy and reliability of the test. In addition, it is also inconvenient to remove the battery from the fixed clamp after the test, which further increases the time cost of operation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery life testing device with a detachable battery clamping structure, comprising a fixed plate, a vertical plate fixedly connected to one end of the fixed plate, a plurality of partitions fixedly connected to one side of the vertical plate above the fixed plate, the spacing between adjacent partitions being gradually increasing, two clamping assemblies symmetrically arranged on both sides of the fixed plate at their central positions, each clamping assembly including a support frame, a through groove opened in the middle of the support frame, a pillar fixedly connected in the through groove, an adjusting slider slidably connected to the outer wall of the pillar, a compression spring sleeved on one side of the outer wall of the pillar near the adjusting slider, an adjusting plate fixedly connected between the two adjusting sliders, and a negative electrode connector fixedly connected to the side of the vertical plate opposite to the adjusting plate at the central position between two adjacent partitions.

[0005] As a further embodiment of this utility model: a plurality of positive electrode connectors are fixedly connected to the side of the adjustment plate facing the upright plate at a position corresponding to the negative electrode connector, and a battery body is movably connected between the negative electrode connector and the positive electrode connector.

[0006] As a further embodiment of this utility model: several pads are fixedly installed above the fixing plate below the battery body. The side of the pads facing the battery body is designed in an arc shape, and the size of the several pads is designed to gradually increase.

[0007] As a further embodiment of this utility model: a limiting plate is fixedly connected above the fixing plate at the other end, and connecting wires are fixedly connected to the opposite sides of the negative electrode connector and the positive electrode connector, wherein the connecting wire connected to the positive electrode connector passes through the limiting plate.

[0008] As a further embodiment of this utility model: a detector is provided below the fixing plate, the fixing plate is fixedly connected above the detector, and the other ends of several connecting wires are all connected to the detector.

[0009] As a further embodiment of this utility model: a display screen is fixedly connected above the detector, and the display screen is located on one side of the fixed plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This lithium battery life testing device with a detachable battery clamping structure, through the setting of clamping components, when the battery body is placed, the adjusting plate is squeezed by the battery body, which drives the adjusting slider to slide on the outer wall of the support column, and at the same time squeezes the compression spring. When the adjusting slider moves to a position that adapts to the size of the battery body, the elastic force of the compression spring will drive the adjusting plate to cooperate with the upright plate to firmly clamp the battery body, so that the positive electrode connector and the negative electrode connector are connected to the positive and negative electrodes of the battery body respectively. This automatic adjustment mechanism not only ensures that the battery body is stably clamped during the test, but also that the clamping force is uniform, effectively avoiding battery damage or poor contact caused by improper clamping, thus improving the stability and reliability of the test. At the same time, this automatic adjustment mechanism also makes it convenient to quickly remove the battery body after the measurement is completed, improving the convenience of operation. 2. This lithium battery life testing device with a detachable battery clamping structure, by setting separators and pads, allows for the selection of appropriate separator spacing based on the size of the battery body when placing the battery body. The battery is placed between two adjacent separators and between the corresponding positive and negative electrode connectors. The arc-shaped surface of the pads fits against the battery surface, supporting the battery body and enabling it to adapt to battery bodies of different sizes, thus enhancing the versatility of the device.

[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0013] like Figure 1-4As shown, this utility model provides a technical solution: a lithium battery life testing device with a detachable battery clamping structure, including a fixed plate 1, a vertical plate 2 fixedly connected to one end of the fixed plate 1, and a plurality of partitions 3 fixedly connected to one side of the vertical plate 2 above the fixed plate 1. The spacing between two adjacent partitions 3 is gradually increasing. This gradually increasing distribution method allows for the selection of appropriate spacing between partitions 3 according to the size of the battery body 8, thereby meeting the placement requirements of battery bodies 8 of different sizes. Two clamping components 4 are symmetrically arranged on both sides of the fixed plate 1 at the middle position. The clamping components 4 include a support frame 401, and a through groove 402 is opened in the middle of the support frame 401. A support column 403 is fixedly connected inside the through groove 402. An adjusting slider 404 is slidably connected to the outer wall of the support column 403. A compression spring 405 is sleeved on one side of the outer wall of the support column 403 near the adjusting slider 404. Because of the compression spring 405, when the compression spring 405 is compressed, its elastic force can drive the adjusting plate 5 closer to the upright plate 2, thereby enabling the positive electrode connector 7 and the negative electrode connector 6 to be stably connected to the positive and negative electrodes of the battery body 8. An adjusting plate 5 is fixedly connected between the two adjusting sliders 404. Because of the clamping assembly 4, when the battery body 8 is placed, the adjusting plate 5 is compressed by the battery body 8, causing the adjusting slider 404 to slide on the outer wall of the support column 403. When the spring 405 is squeezed, the elastic force of the spring 405 drives the adjusting plate 5 and the upright plate 2 to clamp the battery body 8. This automatic adjustment mechanism can ensure that the battery body 8 is stably clamped and the clamping force is uniform, avoiding battery damage or poor contact caused by improper clamping. At the same time, this automatic adjustment mechanism makes it convenient to remove the battery body 8 after measurement. On the side of the upright plate 2 opposite to the adjusting plate 5, a negative electrode connector 6 is fixedly connected in the middle position between two adjacent partitions 3. On the side of the adjusting plate 5 facing the upright plate 2, a number of positive electrode connectors 7 are fixedly connected in the position corresponding to the negative electrode connector 6. The battery body 8 is movably connected between the negative electrode connector 6 and the positive electrode connector 7. Several pads 9 are fixedly installed on the top of the fixing plate 1 below the battery body 8. The side of the pads 9 facing the battery body 8 is arc-shaped. The size of the pads 9 is gradually increasing. Because of the pads 9, the arc-shaped surface of the pads 9 fits against the battery surface and plays a supporting role, preventing the battery body 8 from shifting during the test. The pads 9 can be adapted to battery bodies 8 of different sizes, further improving the versatility of the device. A limiting plate 10 is fixedly connected to the top of the fixing plate 1 at the other end. Connecting wires 11 are fixedly connected to the opposite sides of the negative electrode connector 6 and the positive electrode connector 7. The connecting wire 11 connected to the positive electrode connector 7 passes through the limiting plate 10. Because of the limiting plate 10, the limiting plate 10 limits the connecting wire 11 connected to the positive electrode connector 7, so as to prevent the connecting wires 11 from getting tangled when the adjusting plate 5 moves. A detector 12 is provided below the fixing plate 1. The fixing plate 1 is fixedly connected above the detector 12. The other end of several connecting wires 11 is connected to the detector 12. A display screen 13 is fixedly connected above the detector 12. The display screen 13 is located on one side of the fixing plate 1.

[0014] The working principle of this utility model is as follows: When using this device, select an appropriate spacing between the separators 3 according to the size of the battery body 8, place the lithium battery to be tested between two adjacent separators 3, and place it between the corresponding positive electrode connector 7 and negative electrode connector 6. When the battery body 8 is placed, the adjusting plate 5 in the clamping assembly 4 is squeezed by the battery body 8, and its two ends drive the two adjusting sliders 404 to slide on the outer walls of the two pillars 403 respectively. During the movement, the adjusting sliders 404 squeeze the compression spring 405 until the spacing between the adjusting plate 5 and the upright plate 2 is adapted to the length of the battery body 8. At the same time, the adjusting plate 5... Under the elastic force of the compression spring 405, the positive terminal connector 7 and the negative terminal connector 6 on the upright plate 2 are driven to make close contact with the positive and negative terminals of the battery, thus completing the clamping and fixing of the battery body 8. After the battery body 8 is installed, the connecting wire 11 connects the positive and negative terminals of the battery body 8 to the detector 12. The detector 12 starts to work and monitors and analyzes various performance parameters of the battery body 8 in real time, such as voltage, current, and internal resistance. The life of the battery body 8 is evaluated by the changes in these parameters. The detector 12 transmits the monitored data to the display screen 13, and the battery test results can be viewed intuitively on the display screen 13.
