[0001] This utility model relates to the field of sealing test technology, and in particular to a sealing ring compression gradient test device and test equipment. Background Technology

[0002] With the rapid development of new energy technologies, batteries, as important energy storage devices, are increasingly widely used, covering multiple fields such as electric vehicles, portable electronic devices, and energy storage systems. The sealing performance of a battery is crucial to its safety and reliability, and the sealing ring, as a key component for battery sealing, directly affects the sealing effect and lifespan of the battery.

[0003] For example, patent CN104977102B discloses a pressure testing device for a sealing ring. The electrode is placed in a sealing groove, and the sealing ring to be tested is fitted onto the upper end of the electrode. A pressure rod pushes the pressure sleeve to force the sealing ring into the sealing groove. A pressure sensor is installed at the lower end of the pressure rod. During the downward pressure process, the downward pressure is converted into the pressure of the sealing ring by the pressure sensor, thereby realizing the performance testing of the sealing ring. However, this device can only perform performance testing on one sealing ring at a time, resulting in test results that cannot accurately reflect the performance differences of the sealing ring under different compression levels, affecting the performance evaluation of the sealing ring. Utility Model Content

[0004] In view of this, the present invention proposes a sealing ring compression gradient test device and test equipment, which can solve the problem that the existing test devices can only perform performance tests on one sealing ring at a time, resulting in the test results not being able to accurately reflect the performance differences of the sealing ring under different compression degrees, thus affecting the performance evaluation of the sealing ring.

[0005] The technical solution of this utility model is implemented as follows: This utility model provides a sealing ring compression gradient test device, comprising: A base having multiple spaced-apart test areas for placing sealing rings; and Multiple sets of test components are respectively set in each of the test areas. The test components are used to apply compressive force to the sealing rings in the test areas, and the compressive force applied by at least two sets of test components is different.

[0006] Based on the above technical solutions, preferably, the test components include: A pressure plate is disposed on the test area of ​​the base and covers the sealing ring; and A connecting component connects the pressure plate and the base, and is used to adjust the distance between the pressure plate and the base.

[0007] More preferably, the connecting component includes: A connector that detachably connects the pressure plate and the base; and An adjustment element is provided on the base, and the height of the adjustment element is adjustable.

[0008] More preferably, the adjusting component includes a plurality of height adjusting parts stacked vertically.

[0009] More preferably, the pressure plate has a first threaded hole through it, the base has a second threaded hole at the position where it aligns with the first threaded hole, and the connector is screwed into the first threaded hole and the second threaded hole.

[0010] More preferably, the first threaded hole is located in the middle of the pressure plate, and the second threaded hole is located in the middle of the test area.

[0011] More preferably, multiple sealing rings are provided in the test area, and each sealing ring is distributed at intervals along the circumference of the second threaded hole.

[0012] Based on the above technical solutions, preferably, the height adjustment part has a through hole in the middle, and the connector passes through the through hole.

[0013] Based on the above technical solutions, preferably, the base is provided with a plurality of staggered connecting ribs, and the test area is formed between each of the connecting ribs.

[0014] This invention also provides a testing device, including the sealing ring compression gradient testing device described above.

[0015] The sealing ring compression gradient testing device and equipment of this invention have the following advantages over the prior art: (1) By applying different extrusion forces to the corresponding sealing rings through at least two sets of test components, a comparative test is formed.

(2) By stacking multiple height adjustment parts, the height adjustment of the adjustment parts becomes more flexible and precise. The compression amount can be adjusted by increasing or decreasing the number of height adjustment parts according to actual test requirements, thereby improving the convenience and flexibility of operation.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1 to 4 As shown, this utility model provides a sealing ring compression gradient test device, which includes a base 1 and multiple test components 3. The base 1 has multiple test areas 11 spaced apart, and the test areas 11 are used to place the sealing ring 2. The multiple test components 3 are respectively arranged in each test area 11, and the test components 3 are used to apply compressive force to the sealing ring 2 in the test area 11. At least two sets of test components 3 apply different compressive forces.

[0021] By applying different compressive forces to the corresponding sealing rings 2 using at least two sets of test components 3, a comparative test is formed. After a period of compression, the performance changes of the sealing rings 2 located in the two test areas 11 can be directly observed and analyzed under different degrees of compression. This solves the problem that existing test devices can only perform performance tests on one sealing ring 2 at a time, resulting in test results that cannot accurately reflect the performance differences of the sealing rings 2 under different degrees of compression, thus affecting the performance evaluation of the sealing rings 2.

[0022] In some embodiments, the test assembly 3 includes a pressure plate 31 and a connecting component 32. The pressure plate 31 is disposed on the test area 11 of the base 1 and covers the sealing ring 2. The connecting component 32 is used to connect the pressure plate 31 and the base 1 and to adjust the distance between the pressure plate 31 and the base 1. The pressure plate 31 covers the sealing ring 2, and by adjusting the distance between the pressure plate 31 and the base 1, the compressive force on the sealing ring 2 located between the pressure plate 31 and the base 1 can be adjusted. This facilitates applying different compressive forces to the sealing ring 2 in different test areas 11, making operation convenient and allowing simultaneous testing in each test area 11, thus improving testing efficiency.

[0023] To ensure the pressing effect of the pressure plate 31 on the sealing ring 2, the pressure plate 31 completely covers the sealing ring 2.

[0024] Optionally, the connecting components include a threaded adjustment structure, a structure in which a telescopic rod and a locking nut cooperate, or a structure in which a drive mechanism and an adjusting rod cooperate. The threaded adjustment structure includes a screw and a nut. One end of the screw is connected to the base 1, and the other end of the screw is threaded through a pressure plate 31. The nut is mounted on the screw. By rotating the nut, the position of the screw in the threaded hole is adjusted, thereby adjusting the distance between the pressure plate 31 and the base 1. The structure in which the telescopic rod and the locking nut cooperate includes a telescopic rod and a locking nut. The telescopic rod includes an inner rod and an outer tube. The inner rod is telescopically inserted into the outer tube. The locking nut is mounted on the outer tube. By rotating the locking nut, the inner rod can be fixed at a specific position on the outer tube, thereby adjusting the total length of the telescopic rod. One end of the telescopic rod is mounted on the base 1, and the other end is mounted on the pressure plate 31. The structure in which the drive mechanism cooperates with the adjusting rod includes a drive mechanism and an adjusting rod. The drive mechanism may include a cylinder, a hydraulic cylinder, or an electric push rod, etc. The adjusting rod is located at the movable end of the drive mechanism, which is mounted on the base 1. The adjusting rod is connected to the pressure plate 31. The distance between the base 1 and the pressure plate 31 is adjusted by driving the adjusting rod to move through the drive mechanism. Of course, the connecting component can also be other structures, which will not be described in detail in this embodiment.

[0025] In some embodiments, the connecting component 32 includes a connector 321 and an adjusting component 322. The connector 321 is detachably connected to the pressure plate 31 and the base 1. The adjusting component 322 is disposed on the base 1, and its height is adjustable. The adjusting component 322, positioned on the base 1, is located between the pressure plate 31 and the base 1, thus supporting the pressure plate 31. After the pressure plate 31 is connected to the base 1 via the connector 321, the height of the adjusting component 322, located between the pressure plate 31 and the base 1, represents the distance between them. Therefore, by controlling the height of the adjusting component 322, the compressive force exerted by the pressure plate 31 on the sealing ring 2 located within the test area 11 is controlled.

[0026] The connector 321 can be detachably connected to the pressure plate 31 and the base 1 by means of threaded connection, snap-fit ​​connection or magnetic attraction. The detachable connection between the pressure plate 31 and the base 1 makes it easy to quickly place and remove the sealing ring 2 on the base 1, saving working time, improving work efficiency, improving the convenience of using the device, and also facilitating the subsequent maintenance and cleaning of the device.

[0027] In addition, the height of the adjusting member 322 is adjustable by means of the adjusting member 322 being threadedly connected to the base 1. By changing the connection depth between the adjusting member 322 and the base 1, the height of the adjusting member 322 protruding from the base 1 is adjusted, which also adjusts the distance between the base 1 and the pressure plate 31.

[0028] Optionally, the adjusting component 322 includes multiple height adjusting parts 3221 stacked vertically. This stacked structure allows for more flexible and precise height adjustment of the adjusting component 322. The compression amount can be adjusted by increasing or decreasing the number of height adjusting parts 3221 according to actual testing needs. Of course, the thickness of each height adjusting part 3221 can be exactly the same, partially the same, or completely different. By combining height adjusting parts 3221 of different thicknesses, the compression amount of the sealing ring 2 can be adjusted. Optionally, the thickness accuracy of the height adjusting part 3221 is 0.01, thereby achieving high-precision adjustment.

[0029] like Figures 1 to 4As shown, in some embodiments, a first threaded hole 311 is formed through the pressure plate 31, and a second threaded hole 12 is formed at the position where the base 1 aligns with the first threaded hole 311. The connector 321 is screwed into the first threaded hole 311 and the second threaded hole 12. The connector 321 threadedly connects the pressure plate 31 and the base 1, thereby achieving a detachable connection between the pressure plate 31 and the base 1. This method ensures the reliability of the connection, guarantees a stable connection between the pressure plate 31 and the base 1 during the test, avoids test errors caused by loose connection, and facilitates installation and disassembly, further improving the ease of operation of the device.

[0030] In some embodiments, the first threaded hole 311 is located in the middle of the pressure plate 31, and the second threaded hole 12 is located in the middle of the test area 11. Positioning the threaded hole in the middle allows the compressive force to be transmitted more evenly to the sealing ring 2, further improving the uniformity and accuracy of the test. This ensures that the compressive force distribution on the sealing ring 2 during the test is reasonable, thus enabling the test results to more accurately reflect the actual performance of the sealing ring 2.

[0031] Optionally, a through hole 3222 is provided in the middle of the height adjustment part 3221, and the connector 321 passes through the through hole 3222, thereby allowing the connector 321 to pass smoothly through the height adjustment part 3221, realizing effective cooperation between the connector 321 and the height adjustment part 3221, ensuring the normal operation of the entire connecting component 32, and also facilitating the installation and disassembly of the height adjustment part 3221, further improving the operation convenience and maintenance efficiency of the device.

[0032] In some embodiments, multiple sealing rings 2 are provided within the test area 11, with each sealing ring 2 distributed at circumferential intervals along the second threaded hole 12. This allows multiple sealing rings 2 to be tested simultaneously, and because they are uniformly distributed around the second threaded hole 12, each sealing ring 2 experiences a similar stress environment when subjected to compressive force. This helps improve the consistency and comparability of test results, facilitating batch analysis and comparison of the performance of different sealing rings 2.

[0033] In some embodiments, the base 1 is provided with a plurality of staggered connecting ribs 13, and the test area 11 is formed between each connecting rib 13. The staggered connecting ribs 13 not only enhance the structural strength of the base 1, enabling it to withstand greater compressive force without deformation, thus ensuring the stability and reliability of the testing process, but also naturally form multiple independent test areas 11 through the intervals between the connecting ribs 13, rationally dividing the space, improving space utilization, and providing convenience for testing multiple sealing rings 2 simultaneously, further improving the testing efficiency and practicality of the device. At the same time, the connecting ribs 13 can also play a certain limiting role for the pressure plate 31 in each test area 11.

[0034] In summary, this application provides a sealing ring compression gradient testing device. First, the test plan is determined, namely the number of sealing rings 2 to be placed in the test area 11 and the compression amount of the sealing rings 2. The number of height adjustment parts 3221 in the test area 11 is reasonably combined according to the compression amount. Then, according to the test plan, the sealing rings 2 and the selected adjustment parts 322 are placed into each test area 11 in sequence. Finally, the pressure plate 31 is covered, the connecting parts 321 are screwed in, and each connecting part 321 is screwed to the height limit position, thereby enabling the step test verification. By applying different extrusion forces to the corresponding sealing rings 2 through at least two sets of test components 3, that is, by applying different heights of the adjustment parts 322 in at least two test areas 11, a comparative test is formed. After compression for a period of time, the performance changes of the sealing rings 2 located in the two test areas 11 can be directly observed and analyzed under different compression degrees. This solves the problem that existing test devices can only perform performance tests on one sealing ring 2 at a time, resulting in test results that cannot accurately reflect the performance differences of the sealing ring 2 under different compression degrees, thus affecting the performance evaluation of the sealing ring 2.
