Description

Technical Field

[0001] This utility model relates to the field of lithium battery testing technology, specifically a lithium battery strength testing fixture. Background Technology

[0002] Currently, lithium battery products must comply with standards such as GB31241-2014 "Safety Requirements for Lithium-ion Batteries and Battery Packs for Portable Electronic Products" and UL1642 "Lithium Battery Standard". Qualified lithium batteries need to undergo a battery impact test, which involves testing the battery under heavy impact to determine if it exhibits abnormal behavior such as smoke, combustion, or explosion. This test is typically performed using a lithium battery impact testing machine.

[0003] However, existing lithium battery impact testing machines require different weights to be used depending on the testing requirements to accommodate different specifications of lithium batteries, making the testing inconvenient and slow. Therefore, a lithium battery strength testing fixture is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A lithium battery strength testing fixture of this utility model includes a support frame, a clamping assembly disposed inside the support frame, a drive motor fixedly connected to the outside of the support frame, a winding roller fixedly connected to the output end of the drive motor, a lifting rope fixedly connected to the outside of the winding roller, an impact box fixedly connected to one end of the lifting rope, a connecting pipe connected to the inside of the impact box, a water storage tank fixedly connected to the outside of the support frame, a water pump connected to the outside of the water storage tank, a water delivery pipe connected to the outside of one side of the water pump, and a drain pipe connected to the outside of the other side of the water pump. The water pipes, including both the water supply pipe and the drain pipe, are used in conjunction with the connecting pipe. This step involves setting up an impact box, a water pump, a water supply pipe, and a drain pipe. During use, the water pump on one side can drive water flow from the inside of the water storage tank into the drain pipe, and then inject the water flow into the inside of the impact box through the drain pipe, thereby increasing the weight of the impact box. The water supply pipe can then draw the water flow back into the water storage tank, making it easier to reduce the weight of the impact box. This allows for weight adjustment without replacing the impact box. Then, by lowering the impact box, the lithium battery between the clamping components is impacted, improving the ease of use of the device.

[0006] Preferably, a baffle is fixedly connected to the inner side of the connecting pipe, a torsion spring is fixedly connected to the inner side of the connecting pipe, and a cover plate is fixedly connected to one end of the torsion spring. The cover plate and the connecting pipe are rotatably connected. By setting the baffle, torsion spring, and cover plate, when the impact box is pressed down, the drain pipe and water supply pipe move out from the inner side of the connecting pipe. At this time, under the reset of the torsion spring, the cover plate rotates to fit tightly against the baffle, thereby cooperating with the baffle to further shield the inner side of the impact box. When the impact box drives the water flow to impact the lithium battery, its position can be further restricted, making it difficult for the battery to be discharged, so as to facilitate its subsequent recycling and improve the convenience of the device.

[0007] Preferably, an insert rod is rotatably connected to the inside of the impact box, and both the inside of the impact box and the inside of the insert rod are threaded with fixing screws. This step, by setting the insert rod and fixing screws, allows the insert rod to be rotated to align with the lithium battery when a puncture test is required, and then the fixing screws are rotated and screwed into the inside of the insert rod to fix its position. This facilitates the device to perform puncture tests on the lithium battery using the insert rod, expands the testing range of the device, and improves its practicality.

[0008] Preferably, a limiting rod is fixedly connected to the inner side of the support frame, and a sliding plate is slidably connected to the outer side of the limiting rod. The sliding plate works in conjunction with the impact box. By setting the limiting rod and the sliding plate, the limiting rod can restrict the sliding plate when the impact box is raised or lowered, thereby further restricting the movement trajectory of the impact box and improving the stability of the device.

[0009] Preferably, a fixed frame is fixedly connected to the outside of the support frame, and a door panel is slidably connected to the inside of the fixed frame. By setting up the fixed frame and the door panel, the opening of the support frame can be blocked by moving the door panel when the device is being tested, so that the debris generated by the impact is less likely to fly around, thus improving the safety of the device.

[0010] Preferably, a magnetic plate is fixedly connected to the outside of the support frame. The magnetic plate works in conjunction with the door panel. This step, by setting the magnetic plate, further seals the connection between the door panel and the support frame, and also uses the magnetic plate to adsorb and fix the door panel, thereby improving the stability of the device.

[0011] Preferably, sealing rings are fixedly connected to the outer sides of both the water supply pipe and the drain pipe. This step, by setting sealing rings, further seals the connection pipe, baffle, and cover plate with the water supply pipe and drain pipe, thereby reducing the possibility of dust entering the impact chamber and improving the stability of the device.

[0012] Preferably, the clamping component has an L-shaped clamping end, and the clamping component is used in conjunction with the support frame. This step, by setting the clamping component with an L-shaped clamping end, allows the center of the lithium battery to be suspended when it is fixed, thereby facilitating the use of the insertion rod to perform puncture tests on the lithium battery and improving the ease of use of the device.

[0013] The advantages of this utility model are:

[0014] 1. This utility model, by setting up an impact box, a water pump, a water supply pipe, and a drain pipe, allows water to be pumped from the inside of the water storage tank into the drain pipe during use. The water is then injected into the inside of the impact box through the drain pipe, thus increasing the weight of the impact box. The water supply pipe can then draw the water back into the water storage tank, making it easy to reduce the weight of the impact box. This allows for weight adjustment without replacing the impact box. The impact box is then lowered to impact the lithium battery between the clamping components, improving the ease of use of the device.

[0015] 2. By setting up a baffle, torsion spring, and cover plate, when the impact box is pressed down, the drain pipe and water supply pipe move out from the inside of the connecting pipe. At this time, under the reset of the torsion spring, the cover plate rotates to fit tightly against the baffle, thereby cooperating with the baffle to further block the inside of the impact box. When the impact box drives the water flow to impact the lithium battery, its position can be further restricted, making it difficult for the battery to be discharged, so as to facilitate its subsequent recycling and improve the convenience of the device.

[0016] 3. By setting up an insertion rod and a fixing screw, when a puncture test is required on a lithium battery, the insertion rod can be rotated to align with the lithium battery, and then the fixing screw can be rotated and screwed into the inside of the insertion rod to fix its position. This makes it easier for the device to perform puncture tests on lithium batteries using the insertion rod, thus expanding the testing range of the device and improving its practicality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figure 1-5 As shown, a lithium battery strength testing fixture includes a support frame 1. A clamping assembly 2 is disposed inside the support frame 1. A drive motor 3 is fixedly connected to the outside of the support frame 1. A winding roller 4 is fixedly connected to the output end of the drive motor 3. A lifting rope 5 is fixedly connected to the outside of the winding roller 4. One end of the lifting rope 5 is fixedly connected to an impact box 6. A connecting pipe 7 is connected to the inside of the impact box 6. A water storage tank 8 is fixedly connected to the outside of the support frame 1. A water pump 9 is connected to the outside of the water storage tank 8. A water delivery pipe 10 is connected to the outside of one side of the water pump 9, and a drain pipe 11 is connected to the outside of the other side of the water pump 9. The water delivery pipe 10 and the drain pipe 11... All components are used in conjunction with the connecting pipe 7. This step involves setting up an impact box 6, a water pump 9, a water supply pipe 10, and a drain pipe 11. During use, the water pump 9 on one side drives water flow from the inside of the water storage tank 8 into the drain pipe 11. The water flow is then injected into the inside of the impact box 6 through the drain pipe 11, which facilitates increasing the weight of the impact box 6. The water supply pipe 10 can then draw the water flow back into the inside of the water storage tank 8, making it easier to reduce the weight of the impact box 6. This allows for weight adjustment without replacing the impact box 6. Then, by lowering the impact box 6, the lithium battery between the clamping components 2 is impacted, improving the ease of use of the device.

[0027] Furthermore, such as Figure 3 and Figure 5 As shown, a baffle 12 is fixedly connected to the inner side of the connecting pipe 7, and a torsion spring 13 is fixedly connected to the inner side of the connecting pipe 7. A cover plate 14 is fixedly connected to one end of the torsion spring 13. The cover plate 14 and the connecting pipe 7 are rotatably connected. By setting the baffle 12, torsion spring 13 and cover plate 14, when the impact box 6 is pressed down, the drain pipe 11 and water supply pipe 10 move out from the inner side of the connecting pipe 7. At this time, under the reset of the torsion spring 13, the cover plate 14 rotates to fit tightly against the baffle 12, thereby cooperating with the baffle 12 to further shield the inner side of the impact box 6. When the impact box 6 drives the water flow to impact the lithium battery, its position can be further restricted, making it difficult for the battery to be discharged, so as to facilitate its subsequent recycling and improve the convenience of the device.

[0028] Furthermore, such as Figure 4 As shown, an insertion rod 15 is rotatably connected to the inner side of the impact box 6. Both the inner side of the impact box 6 and the inner side of the insertion rod 15 are threadedly connected to a fixing screw 16. By setting the insertion rod 15 and the fixing screw 16, when a puncture test is required on the lithium battery, the insertion rod 15 can be rotated to align with the lithium battery, and then the fixing screw 16 can be rotated and screwed into the inner side of the insertion rod 15 to fix its position. This allows the device to perform puncture tests on the lithium battery using the insertion rod 15, expanding the testing range of the device and improving its practicality.

[0029] Furthermore, such as Figure 1 As shown, a limiting rod 17 is fixedly connected to the inner side of the support frame 1, and a sliding plate 18 is slidably connected to the outer side of the limiting rod 17. The sliding plate 18 is used in conjunction with the impact box 6. By setting the limiting rod 17 and the sliding plate 18, when the impact box 6 is raised or lowered, the limiting rod 17 can restrict the sliding plate 18, thereby further restricting the movement trajectory of the impact box 6 and improving the stability of the device.

[0030] Furthermore, such as Figure 2 As shown, a fixed frame 19 is fixedly connected to the outer side of the support frame 1, and a door panel 20 is slidably connected to the inner side of the fixed frame 19. By setting up the fixed frame 19 and the door panel 20, the opening of the support frame 1 can be blocked by moving the door panel 20 when the device is being tested, so that the debris generated by the impact is not easy to fly around, thus improving the safety of the device.

[0031] Furthermore, such as Figure 2As shown, a magnetic plate 21 is fixedly connected to the outside of the support frame 1. The magnetic plate 21 and the door panel 20 are used together. This step improves the stability of the device by setting the magnetic plate 21 to further seal the connection between the door panel 20 and the support frame 1, and to adsorb and fix the door panel 20.

[0032] Furthermore, such as Figure 5 As shown, sealing rings 22 are fixedly connected to the outer sides of both the water supply pipe 10 and the drain pipe 11. By setting the sealing rings 22, the connecting pipe 7, the baffle 12, and the cover plate 14 can be further sealed with the water supply pipe 10 and the drain pipe 11, thereby reducing the possibility of dust entering the inner side of the impact box 6 and improving the stability of the device.

[0033] Furthermore, such as Figure 1 As shown, the clamping component 2 has an L-shaped clamping end. The clamping component 2 and the support frame 1 are used together. This step, by setting the clamping component 2 with an L-shaped clamping end, allows the center of the lithium battery to be suspended when it is fixed, which facilitates the use of the insertion rod 15 to perform a puncture test on the lithium battery and improves the ease of use of the device.

[0034] Working principle: During use, water is pumped from the inside of the water tank 8 into the drain pipe 11 via the water pump 9 on one side. The water is then injected into the inside of the impact box 6 through the drain pipe 11, which increases the weight of the impact box 6. The water can be drawn back into the water tank 8 through the water supply pipe 10, which makes it easier to reduce the weight of the impact box 6 until there is enough water inside the impact box 6. The lithium battery is then placed inside the clamping assembly 2 and fixed. The drive motor 3 is then started, which drives the winding roller 4 to rotate, causing the lifting rope 5 to unfold. This causes the impact box 6 to press down and impact the lithium battery.
