Description

Technical Field

[0001] This utility model relates to the field of battery measurement technology, specifically a device for facilitating battery measurement. Background Technology

[0002] With the rapid development of technology and people's increasing reliance on portable electronic devices, batteries, as a core component of energy supply, are being used more and more widely in daily life and industrial fields. From smartphones and laptops to electric vehicles and energy storage systems, batteries provide reliable power support for various devices, greatly promoting the convenience and efficiency of modern society.

[0003] To prevent safety issues such as fires and explosions during battery use, the performance of individual cells in high-voltage or battery pack combinations must be consistent. During battery production, differences can easily exist between individual cells due to factors such as raw material characteristics and the precision of production process control. Therefore, it is necessary to screen individual cells and combine them with those having similar performance to ensure the stability and safety of the entire battery pack. Currently, the performance testing of individual cells mainly relies on manual measurement of voltage, internal resistance, and other data using multimeters. This method is inefficient and cannot meet the needs of large-scale production line battery performance evaluation.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] The aforementioned problem that existing methods for testing the performance of individual cells often rely on manual measurement using multimeters, resulting in low measurement efficiency and difficulty in meeting the battery performance evaluation needs of large-scale production lines, is addressed by the following technical solution adopted by this invention:

[0006] A device for facilitating battery measurement includes a device body, the device body including a support plate for placing the battery, a clamping plate movably hinged to the support plate and connected to an external tester, and a drive mechanism, the clamping plate including a detection part and a reset part, the drive mechanism including a drive source and a pressing block connected to the output end of the drive source, and the reset part having an elastic element on the side away from the pressing block;

[0007] When the drive source drives the extrusion block closer to the reset part, the elastic element undergoes elastic deformation, so that the detection part moves away from the support plate;

[0008] When the drive source drives the squeezing block away from the reset part, the elastic element restores its elastic deformation so that the detection part moves closer to the support plate.

[0009] Furthermore, the clamping plate includes a first clamping plate for connecting the positive terminal of the battery and a second clamping plate corresponding to the first clamping plate for connecting the negative terminal of the battery.

[0010] Furthermore, the first clamp is made of insulating material, and the first clamp is provided with test lines for connecting an external tester. The detection part includes a first detection surface located on the first clamp, and a conductive layer is provided on the first detection surface. One side of the test line extends into the first clamp and is connected to the conductive layer.

[0011] Furthermore, the detection unit and the reset unit are connected at an angle to form a rounded corner.

[0012] Furthermore, the thickness of the detection part is greater than the thickness of the reset part.

[0013] Furthermore, the reset part includes a first reset part located on the first clamping plate and a second reset part located on the second clamping plate, and the elastic member includes a first spring member located between the first reset part and the support plate and a second spring member located between the second reset part and the support plate.

[0014] Furthermore, the driving source includes a first driving cylinder located above the first clamping plate and a second driving cylinder located above the second clamping plate, and the extrusion block is connected to the first driving cylinder and the second driving cylinder respectively.

[0015] Furthermore, the support plate and the clamping plate are provided with a hinge mechanism on the side away from the elastic member. The hinge mechanism includes a hinge mounting seat on the support plate, a hinge hole on the clamping plate, and a hinge shaft connected to the hinge mounting seat and the hinge hole respectively.

[0016] Furthermore, the reset part is provided with anti-slip stripes on the side near the extrusion block to increase friction.

[0017] Furthermore, the conductive layer is made of copper.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention features a support plate, a clamping plate, and a driving mechanism. The clamping plate includes a detection section and a reset section. An elastic element is provided between the reset section and the support plate. Under normal conditions, the pressing block presses down on the reset section, causing the elastic element to deform elastically. The support plate and the clamping plate are hinged, separating the detection section from the support plate. When a user needs to test the performance of a single battery cell, the tab of the battery to be tested is placed on the support plate. The driving source drives the pressing block away from the reset section, and the elastic element recovers its elastic deformation. The elastic element drives the reset section to move upward, and the detection section to move downward. The detection section and the support plate clamp the tab of the battery to be tested. The clamping plate is connected to an external testing instrument, allowing the user to obtain the performance data of the single battery cell through the testing instrument. This facilitates the rapid contact and separation of the detection section and the battery, improving testing efficiency. It effectively solves the problem that the existing single battery cell performance testing often relies on manual measurement with a multimeter, resulting in low measurement efficiency and difficulty in meeting the battery performance evaluation needs of large-scale production lines.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 6The device shown is for measuring batteries and includes a device body 1. The device body 1 includes a support plate 2 for placing batteries, a clamping plate 3 that is movably hinged to the support plate 2 and connected to an external tester, and a drive mechanism 4. The clamping plate 3 includes a detection part 51 and a reset part 52. The drive mechanism 4 includes a drive source 41 and a pressing block 42 connected to the output end of the drive source 41. An elastic element 6 is provided on the side of the reset part 52 away from the pressing block 42.

[0029] When the drive source 41 drives the pressing block 42 to approach the reset part 52, the elastic member 6 undergoes elastic deformation, so that the detection part 51 moves away from the support plate 2.

[0030] When the drive source 41 drives the pressing block 42 away from the reset part 52, the elastic member 6 restores its elastic deformation so that the detection part 51 moves closer to the support plate 2;

[0031] This invention features a support plate, a clamping plate, and a driving mechanism. The clamping plate includes a detection section and a reset section. An elastic element is provided between the reset section and the support plate. Under normal conditions, the pressing block presses down on the reset section, causing the elastic element to deform elastically. The support plate and the clamping plate are hinged, separating the detection section from the support plate. When a user needs to test the performance of a single battery cell, the tab of the battery to be tested is placed on the support plate. The driving source drives the pressing block away from the reset section, and the elastic element recovers its elastic deformation. The elastic element drives the reset section to move upward, and the detection section to move downward. The detection section and the support plate clamp the tab of the battery to be tested. The clamping plate is connected to an external testing instrument, allowing the user to obtain the performance data of the single battery cell through the testing instrument. This facilitates the rapid contact and separation of the detection section and the battery, improving testing efficiency. It effectively solves the problem that the existing single battery cell performance testing often relies on manual measurement with a multimeter, resulting in low measurement efficiency and difficulty in meeting the battery performance evaluation needs of large-scale production lines.

[0032] Optionally, in some embodiments, the elastic element 6 is an elastic rubber block. Rubber has good elasticity and flexibility. In addition, the hardness of the rubber can be adjusted as needed to meet different elasticity requirements. Furthermore, rubber has low cost, is easy to install, and can adapt to installation spaces of different shapes.

[0033] Optionally, in some embodiments, the elastic element 6 is an elastic silicone block. Silicone also has the characteristics of being soft and elastic. In addition, silicone has good insulation properties and will not interfere with the battery detection results. Secondly, silicone has a large surface friction, which can increase the contact stability between the reset part 52 and the support plate 2.

[0034] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the elastic element 6 is a spring element.

[0035] Optionally, in some embodiments, the drive source 41 is a stepper motor. Stepper motors have high precision, enabling accurate positioning control and good repeatability. Secondly, stepper motors have fast response speed, enabling rapid start and stop. Finally, stepper motors can output large torque at low speeds.

[0036] Optionally, in some embodiments, the drive source 41 is a servo motor, which has high precision and high response speed and can adjust the position of the extrusion block 42 in real time according to the feedback signal.

[0037] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the drive source 41 is a drive cylinder.

[0038] Furthermore, the detection unit 51 and the reset unit 52 are integrally formed. This integral forming arrangement makes the detection unit 51 and the reset unit 52 a continuous and complete structure without any splicing or connecting parts, thereby avoiding structural damage caused by problems such as loosening or breakage of connection points.

[0039] like Figures 1 to 6 The clamping plate 3 shown includes a first clamping plate 31 for connecting the positive terminal of the battery and a second clamping plate 32 corresponding to the first clamping plate 31 and for connecting the negative terminal of the battery.

[0040] Furthermore, the first clamping plate 31 and the second clamping plate 32 correspond to the positive and negative terminals of the battery, respectively, which helps to clearly distinguish the polarity and avoid measurement errors or equipment damage caused by reverse polarity during the testing process.

[0041] Furthermore, with the corresponding first clamp 31 and second clamp 32, users can quickly and accurately connect the battery tabs to be tested to the first clamp 31 and the second clamp 32 respectively, which helps to reduce operation time and effectively improve testing efficiency.

[0042] like Figures 1 to 6 The first clamp 31 shown is made of insulating material. The first clamp 31 is provided with test lines 7 for connecting to an external tester. The detection part 51 includes a first detection surface 511 located on the first clamp 31. A conductive layer is provided on the first detection surface 511. One side of the test line 7 extends into the first clamp 31 and is connected to the conductive layer.

[0043] Specifically, the conductive layer on the first detection surface 511 is connected to the test line 7, which ensures that the electrical signal of the battery under test is accurately and stably transmitted to the external tester. The conductive layer has good conductivity, which can reduce resistance and loss during signal transmission and ensure the integrity of the electrical signal. Secondly, the first clamping plate 31 is made of insulating material, which can effectively prevent current from being conducted from the first clamping plate 31 to other parts or operators. During battery testing, the voltage and current of the battery may pose safety hazards to the surrounding environment and personnel. The insulating first clamping plate 31 limits the current to a specific conductive path, prevents leakage accidents, and ensures the personal safety of operators and the normal operation of equipment.

[0044] Furthermore, the second clamping plate 32 is configured the same as the first clamping plate 31. The second clamping plate 32 is also made of insulating material. The detection unit 51 includes a second detection surface 512 located on the second clamping plate 32. A conductive layer is also provided on the second detection surface 512. A test line 7 for connecting an external tester is provided on the second clamping plate 32. One side of the test line 7 extends into the second clamping plate 32 and is connected to the conductive layer.

[0045] Optionally, in some embodiments, both the first clamping plate 31 and the second clamping plate 32 are made of polycarbonate material, which has high transparency, high strength and excellent insulation properties, and good heat resistance.

[0046] Optionally, in some embodiments, both the first clamping plate 31 and the second clamping plate 32 are made of polyamide material, which has good mechanical strength, wear resistance and insulation properties.

[0047] Optionally, in some embodiments, both the first clamping plate 31 and the second clamping plate 32 are made of polypropylene. Polypropylene has good chemical stability and is not easily corroded. Secondly, polypropylene has a low density and is lightweight, which reduces the overall weight of the clamping plate 3, making it easier to operate and install. Finally, polypropylene has excellent insulation properties, which can effectively prevent current conduction and ensure electrical safety.

[0048] Optionally, in some embodiments, the conductive layer is made of a copper-nickel alloy, which is a metal with excellent electrical conductivity, good corrosion resistance, tensile strength and compressive strength, and can withstand large mechanical stress.

[0049] Optionally, in some embodiments, the conductive layer is made of aluminum, which has good conductivity, low density, and light weight.

[0050] Furthermore, as a preferred embodiment of this invention and not a limitation thereof, the conductive layer is made of copper.

[0051] like Figures 1 to 6The detection unit 51 and the reset unit 52 shown are connected at an angle to form a rounded corner;

[0052] Furthermore, the rounded corner setting can avoid the formation of sharp edges in the connection area between the detection part 51 and the reset part 52. During the use of the device body 1, the clamping plate 3 will bear a certain stress. Sharp edges will cause stress concentration, making the clamping plate 3 prone to fatigue cracks or even breakage. The rounded corner can evenly distribute the stress to a larger area, reduce local stress, thereby enhancing the structural strength and durability of the connection part and extending the service life of the device.

[0053] Furthermore, sharp edges and corners can easily cause accidental injuries such as scratches to operators. Rounding the corners makes the connection between the detection part 51 and the reset part 52 smooth, which helps to reduce the risk of accidental injury to operators and helps to ensure the safety of operators in daily operation and maintenance.

[0054] Furthermore, during the battery testing process, the detection unit 51 will come into contact with the battery tabs and other parts. If the connection between the detection unit 51 and the reset unit 52 has sharp edges, it may scratch or damage the battery during the contact process, affecting the battery's performance and lifespan. The smooth surface with rounded corners can reduce the risk of damage to the battery and ensure the battery's integrity and safety.

[0055] like Figures 1 to 6 The thickness of the detection unit 51 shown is greater than the thickness of the reset unit 52;

[0056] Furthermore, the detection unit 51 needs to be in direct contact with the battery tabs and withstand a certain pressure. Increasing the thickness of the detection unit 51 can improve its mechanical strength and rigidity, and avoid affecting the detection accuracy due to deformation or damage caused by force.

[0057] Furthermore, the detection unit 51 needs to be provided with a conductive layer to achieve electrical connection. Increasing the thickness of the detection unit 51 can provide more stable support for the conductive layer and prevent the conductive layer from falling off or being damaged due to insufficient thickness.

[0058] Furthermore, the thicker detection section 51 can better withstand the contact pressure with the battery tab, ensuring uniform contact area and contact force between the conductive layer and the battery tab, thereby improving the stability and accuracy of the detection signal.

[0059] like Figures 1 to 6 The reset part 52 shown includes a first reset part 521 located on the first clamping plate 31 and a second reset part 522 located on the second clamping plate 32. The elastic member 6 includes a first spring member 61 located between the first reset part 521 and the support plate 2, and a second spring member 62 located between the second reset part 522 and the support plate 2.

[0060] Furthermore, the first reset part 521 and the second reset part 522 are respectively provided with independent first spring members 61 and second spring members 62, which can ensure that the first clamping plate 31 and the second clamping plate 32 are more accurate and stable during reset, which helps to avoid the problem of incomplete or uneven reset caused by the failure of a single elastic member 6. The first spring members 61 and the second spring members 62 can reduce mechanical interference between the first clamping plate 31 and the second clamping plate 32, ensuring that the reset action of the first clamping plate 31 and the second clamping plate 32 is independent and accurate.

[0061] Furthermore, the first spring 61 and the second spring 62 can be replaced independently. When one of the springs is damaged, the user does not need to replace the entire spring 6, which helps to reduce maintenance costs. The first spring 61 and the second spring 62 are designed to make maintenance and replacement more convenient, which helps to reduce maintenance time and effectively improve the availability of the device.

[0062] Furthermore, the elastic elements 6 are a first spring element 61 and a second spring element 62. Both the first spring element 61 and the second spring element 62 have excellent elastic properties, and can deform when subjected to force and quickly return to their original shape after the force is released, which helps to ensure the stable and reliable operation of the reset part 52 and the detection part 51.

[0063] like Figures 1 to 6 The drive source 41 shown includes a first drive cylinder 411 located above the first clamping plate 31 and a second drive cylinder 412 located above the second clamping plate 32. The pressing block 42 is connected to the first drive cylinder 411 and the second drive cylinder 412 respectively.

[0064] Optionally, in some embodiments, the drive source 41 is a drive cylinder, and the number of drive cylinders is one. A single drive cylinder controls the extrusion block 42 to simultaneously move closer to or away from the first clamping plate 31 and the second clamping plate 32. Using a single drive cylinder can simplify the overall structure of the device, reduce the number of parts and complexity, thereby reducing manufacturing costs and maintenance difficulty.

[0065] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the driving source 41 includes a first driving cylinder 411 located above the first clamping plate 31 and a second driving cylinder 412 located above the second clamping plate 32. Both driving cylinders are connected to the pressing block 42 simultaneously. The simultaneous operation of the two driving cylinders can provide a greater combined force than a single driving cylinder. During the battery testing process, the greater driving force can ensure that the pressing block 42 applies sufficient pressure to the first clamping plate 31 and the second clamping plate 32, so that the first clamping plate 31 and the second clamping plate 32 can clamp the battery tabs more firmly, ensuring the stability of the electrical connection, thereby improving the accuracy and reliability of the test results.

[0066] like Figures 1 to 6 The support plate 2 and clamping plate 3 shown are provided with a hinge mechanism 8 on the side away from the elastic member 6. The hinge mechanism 8 includes a hinge mounting seat 81 located on the support plate 2, a hinge hole 82 located on the clamping plate 3, and a hinge shaft 83 connected to the hinge mounting seat 81 and the hinge hole 82 respectively.

[0067] Furthermore, the hinge mechanism 8 provides a rotatable fulcrum for the clamping plate 3, which can rotate flexibly relative to the support plate 2 around the hinge axis 83, so that the clamping plate 3 can perform clamping or releasing operations more smoothly. During the battery testing process, the clamping plate 3 opens and closes to insert or remove the battery, which greatly improves the convenience and efficiency of operation.

[0068] Furthermore, the hinge mechanism 8, through the combination of the hinge mounting base 81, the hinge hole 82 and the hinge shaft 83, can ensure a more stable connection between the support plate 2 and the clamping plate 3, which helps to reduce loosening caused by external forces or vibrations.

[0069] like Figures 1 to 6 The reset part 52 shown is provided with anti-slip stripes 520 on the side near the extrusion block 42 to increase friction.

[0070] Furthermore, the anti-slip stripes 520 can increase the friction between the reset part 52 and the pressing block 42, preventing relative sliding between the two during movement and ensuring more stable contact.

[0071] Furthermore, the anti-slip stripes 520 reduce the sliding friction between the reset part 52 and the pressing block 42, so that the transmission of driving force is more efficient and energy loss due to slippage is avoided.

[0072] Optionally, in some embodiments, the anti-slip stripes 520 are evenly distributed in a horizontal straight line on the side of the reset part 52 near the extrusion block 42. The horizontal straight anti-slip stripes 520 can effectively increase the friction in the horizontal direction and prevent the extrusion block 42 from sliding in the horizontal direction.

[0073] Optionally, in some embodiments, the anti-slip stripes 520 are horizontal and vertical straight stripes that intersect to form a grid structure. The intersecting anti-slip stripes 520 can provide greater friction in all directions, ensuring a tight fit between the extrusion block 42 and the reset part 52, and improving the stability and reliability of the equipment.

[0074] Optionally, in some embodiments, the anti-slip stripes 520 are distributed in a wavy pattern. The wavy anti-slip stripes 520 can better adapt to the surface shape of the extrusion block 42, increase the contact area, and thus improve the friction.

[0075] like Figures 1 to 6 The conductive layer shown is made of copper.

[0076] Furthermore, copper is a metal with excellent electrical conductivity and relatively low resistivity. When copper is used in the conductive layer, it ensures smooth current transmission and reduces energy loss during transmission. In battery testing, the highly conductive copper conductive layer can ensure accurate and stable transmission of the detection signal, reduce interference caused by resistance, and thus improve the accuracy of the detection results.

[0077] Furthermore, copper not only has good electrical conductivity, but also excellent thermal conductivity. When current passes through the conductive layer, a certain amount of heat is generated due to resistance. Good thermal conductivity allows the heat to dissipate quickly, preventing the conductive layer from being damaged due to excessive temperature and extending its service life.

[0078] The implementation method of Example 1 is as follows:

[0079] A device for facilitating battery measurement includes a device body 1. The device body 1 includes a support plate 2 for placing the battery, a clamping plate 3 movably hinged to the support plate 2 and connected to an external testing instrument, and a drive mechanism 4. The clamping plate 3 includes a detection part 51 and a reset part 52. The drive mechanism 4 includes a drive source 41 and a pressing block 42 connected to the output end of the drive source 41. An elastic element 6 is provided on the side of the reset part 52 away from the pressing block 42. The clamping plate 3 includes a first clamping plate 31 for connecting the positive terminal of the battery and a second clamping plate 32 corresponding to the first clamping plate 31 for connecting the negative terminal of the battery. Both the first clamping plate 31 and the second clamping plate 32 are made of polycarbonate material, and both the first clamping plate 31 and the second clamping plate 32 are provided with test lines 7. The detection part 51... The system includes a first detection surface 511 located on the first clamping plate 31 and a second detection surface 512 located on the second clamping plate 32. Both the first detection surface 511 and the second detection surface 512 are provided with conductive layers made of copper. One side of each of the two test lines 7 extends into the first clamping plate 31 and the second clamping plate 32 respectively and connects to the conductive layers.

Both the first driving cylinder 411 and the second driving cylinder 412 are simultaneously connected to the pressing block 42. The elastic element 6 includes a first spring 61 located between the first clamping plate 31 and the support plate 2, and a spring 61 located between the second clamping plate 32 and the support plate 2. Under normal conditions, the first drive cylinder 411 and the second drive cylinder 412 simultaneously drive the pressing block 42 to press the first clamping plate 31 and the second clamping plate 32 vertically downwards. The first spring 61 and the second spring 62 are compressed, and the reset parts 52 on the first clamping plate 31 and the second clamping plate 32 move closer to the support plate 2, causing the detection parts 51 on the first clamping plate 31 and the second clamping plate 32 to move away from the support plate 2. At this time, the operator can place the two tabs of the battery to be tested on the support plate 2 respectively, and activate the first drive cylinder 411 and the second drive cylinder 412. The first drive cylinder 411 and the second drive cylinder 412 simultaneously drive the pressing block 42 away from the first clamping plate 31 and the second clamping plate 32. The clamping plate 32, the first spring 61 and the second spring 62 restore their elastic deformation, and the first spring 61 and the second spring 62 support the reset part 52 on the first clamping plate 31 and the second clamping plate 32 vertically upward. At this time, the first detection surface 511 on the first clamping plate 31 and the second detection surface 512 on the second clamping plate 32 move towards the support plate 2. The first detection surface 511 and the second detection surface 512 cooperate with the support plate 2 to clamp the two tabs of the battery to be tested. At this time, the user can test the performance of the battery through an external tester, which effectively solves the problem that the performance testing of existing single batteries often relies on manual measurement with a multimeter, which is inefficient and difficult to meet the battery performance evaluation needs of large-scale production lines.

[0080] The implementation method of Example 2 is as follows:

[0089] The difference between Example 6 and Example 1 is that the first clamping plate 31 and the second clamping plate 32 are both made of polyamide material, which has good mechanical strength, wear resistance and insulation properties.

[0090] The implementation method of Example 7 is as follows:

[0091] The difference between Example 7 and Example 1 is that: both the first clamping plate 31 and the second clamping plate 32 are made of polypropylene. Polypropylene has good chemical stability and is not easily corroded; secondly, polypropylene has a low density and light weight, so that the overall weight of the clamping plate 3 is reduced, making it easier to operate and install; finally, polypropylene has excellent insulation properties, which can effectively prevent current conduction and ensure electrical safety.
