However, the aging test process is usually time-consuming and the test steps are cumbersome, requiring high technical level and proficiency of testers, especially when the test process is frequently switched between different models, the complexity of the operation is further increased.

[0003] During the inverter aging test, the product needs to be transferred from the assembly line to the aging room, and then the cables are connected and various switches are operated to meet the requirements of the test environment. In this process, the turnover of the product increases the time and site requirements. At the same time, human errors may occur when operating cables and switches, bringing electrical risks and even causing safety hazards to personnel and property.

[0004] Chinese patent CN112098754B discloses an electronic component aging test seat and an aging test device thereof, wherein the electronic component has an input terminal and an output terminal, and the aging test seat comprises: a base, a mounting seat slidably mounted on the base, a test output docking seat connected to the base, a telescopic mechanism 1 connected to the mounting seat, a test input docking seat mounted opposite to the test output docking seat, and a telescopic mechanism 2 connected to the test input docking seat. This patent uses a mounting seat that is slidably arranged to enable the mounting seat and the test seat to be electrically connected, but during the connection process, there is a situation where the docking cannot be aligned, and the connection is not in place and is unstable.

However, the structure of the device is relatively large and it is difficult to be directly used on the test socket of the inverter. Although the clamping structure can improve the stability of the connection, it is not suitable for installation on the test socket of the inverter due to its large size.

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] like Figures 1 to 5 As shown: 1. A micro inverter 4 aging test device, comprising a test seat 1 and a mounting seat 2 that can slide toward the test seat 1, characterized in that a mounting plate 21 electrically connected to the inverter 4 is provided on one end of the mounting seat 2 close to the test seat 1, and a plurality of slots 211 for aging testing are provided on the side of the mounting plate 21 close to the test seat 1; a connector 11 matching the slots 211 on the mounting plate 21 is provided on the test seat 1; and two ends of the test seat 1 in the length direction are provided with slots that can drive the mounting plate 21 to slide along the width direction of the test seat 1 after the mounting plate 21 contacts the test seat 1. The driving assembly 3 is movable; the driving assembly 3 includes two clamping arms 31 that can rotate relative to each other, the two clamping arms 31 are in a mirror-symmetrical state, and the two clamping arms 31 are both L-shaped structures; two first pulleys 32 are provided at both ends of the mounting plate 21 in the length direction, and the two first pulleys 32 are respectively slidably matched with the two clamping arms 31; when the mounting plate 21 is in contact with the test seat 1, the two clamping arms 31 are relatively rotated, so that the two clamping arms 31 are respectively in contact with the two first pulleys 32 and drive the first pulley 32 to slide along the inner side of the clamping arms 31, thereby driving the mounting plate 21 to move toward the test seat 1.

[0034] First, the inverter 4 is placed on the mounting seat 2, and the inverter 4 is electrically connected to the mounting plate 21. At this time, the mounting seat 2 is driven to move toward the test seat 1 through a sliding device (such as a transmission belt or a rail trolley), thereby driving the mounting plate 21 to move until the slot 211 on the mounting plate 21 can contact the connector 11 on the test seat 1. When the mounting plate 21 contacts the test seat 1, the sliding device stops, and the driving component 3 starts to work. The two clamping arms 31 of the driving component 3 are relatively rotated to contact the two first pulleys 32 on the mounting plate 21. Since the two clamping arms 31 are arranged in a mirror-symmetrical manner, and the clamping arms 31 are L-shaped structures, after the first pulley 32 contacts the clamping arms 31, the rotation of the clamping arms 31 can drive the first pulley 32 to slide along the inner side of the clamping arms 31, and the movement of the mounting plate 21 is driven by the first pulley 32, so that the mounting seat 2 moves toward the test seat 1, ensuring that the slot 211 and the connector 11 can be stably plugged, thereby realizing the aging test of the inverter 4.

[0035] The cooperation between the first pulley 32 and the clamping arm 31 provides a stable driving mode, so that the slot 211 on the mounting plate 21 can achieve a stable connection with the connector 11 of the test seat 1, avoiding the problem of unstable contact caused by vibration when the traditional sliding device drives the mounting seat 2 to contact the test seat 1, and helps to accurately control the sliding direction and speed of the mounting plate 21, thereby ensuring the accuracy and reliability of the test results during the aging test. Through precise plug-in and stable driving mechanism, it is ensured that the electrical connection of the micro inverter 4 during the aging test is not disturbed, thereby improving the reliability of the test and the credibility of the data, and avoiding test errors caused by poor plug-in.

[0036] like Figures 2 to 7 As shown: the driving assembly 3 also includes a driving member 33 and two connecting rods 311. The driving member 33 can be slidably arranged on the test seat 1 along the width direction of the test seat 1. The two connecting rods 311 are respectively located on the sides of the two clamping arms 31. One end of the two connecting rods 311 is hinged to the driving member 33, and the other ends of the two connecting rods 311 are respectively hinged to the middle of the two clamping arms 31.

[0037] By moving the driving member 33, the driving member 33 slides along the width direction of the test seat 1, which can drive the two connecting rods 311 hinged thereto. Since the two clamping arms 31 are relatively rotatable and arranged beside the two connecting rods 311, the movement of the connecting rods 311 can drive the two clamping arms 31 to rotate around the connection points with the test seat 1. When the driving member 33 is away from the mounting plate 21, the two clamping arms 31 are close to each other. When the driving member 33 is close to the mounting plate 21, the two clamping arms 31 are away from each other. In the initial state, the two clamping arms 31 are In the state of being away from each other, the driving member 33 slides on the test seat 1 toward the side away from the mounting plate 21 through the approach of the mounting plate 21, thereby driving the two clamping arms 31 to approach each other, thereby clamping the two first pulleys 32 on the mounting plate 21, so that the first pulley 32 can slide along the inner side of the clamping arm 31. Through the movement of the first pulley 32, the mounting plate 21 gradually moves closer to the test seat 1, ensuring that the slot 211 on the mounting plate 21 and the connector 11 on the test seat 1 can be stably and accurately docked, thereby completing the aging test of the inverter 4.

[0038] Through the synergistic effect of the driving member 33 and the connecting rod 311, the rotation of the clamping arm 31 and the sliding of the first pulley 32 can be accurately controlled, so that the mounting plate 21 and the test seat 1 can be stably and accurately docked, which significantly improves the contact stability during the test process and avoids the influence of the plug-in error on the aging test results. The driving member 33 drives the connecting rod 311 by sliding to realize the rotation of the clamping arm 31, which has high flexibility and adjustability. The design can adjust the position of the clamping arm 31 by adjusting the position of the driving member 33 according to different operating requirements, effectively ensuring the precise docking of the device during the test. Compared with the traditional complex drive system, the device adopts a simple combination of the connecting rod 311 and the clamping arm 31, which is compact and efficient. Through the sliding control of the driving member 33, the rotation of the clamping arm 31 and the movement of the first pulley 32 are realized, which simplifies the design of the device and improves the working efficiency of the device. The device can ensure that each plug-in during the aging test of the inverter 4 can remain stable, avoid the test data error caused by poor plug-in, improve the accuracy and reliability of the test, and ensure the repeatability and credibility of the test results.

[0039] like Figures 2 to 7 As shown: conical transmission members 212 are provided at both ends of the mounting plate 21 in the length direction, the axis of the transmission member 212 is arranged in a horizontal state, the diameter of the transmission member 212 on the side away from the mounting plate 21 is smaller than the diameter on the side close to the mounting plate 21, and a mounting sleeve 12 matching the transmission member 212 is provided on the end of the driving member 33 close to the mounting plate 21. When the mounting plate 21 contacts the test seat 1, the transmission member 212 can be inserted into the mounting sleeve 12 and drive the driving member 33 to move.

[0040] When the slot 211 on the mounting plate 21 is driven to dock with the connector 11 of the test socket 1 through the sliding device, there will still be a problem of inaccurate docking, which will affect the subsequent driving of the mounting plate 21 by the drive component 3. By setting a conical transmission member 212 at both ends of the mounting plate 21, the transmission member 212 can match the mounting sleeve 12 on the drive member 33, and accurately insert into the mounting sleeve 12 when the mounting plate 21 contacts the test socket 1, and drive the drive member 33 to perform a small displacement, thereby ensuring the precise control of the drive component 3, reducing the error caused by unstable plug-in, and improving the stability during the test process.

[0041] Due to the conical structure of the transmission member 212, the gradually transitioning diameter of the transmission member 212 can ensure that a uniform contact surface is formed when the mounting sleeve 12 is inserted, thereby achieving a more stable and accurate power transmission. In this way, the driving member 33 can move smoothly and without gaps, thereby avoiding the vibration problem that may occur in the traditional system, achieving precise docking while ensuring the stability of the plug-in. Possible jamming and unnecessary friction are avoided, and the smoothness of the driving process is improved. The wear or damage that may be caused by long-term use is reduced, and the durability of the device is enhanced.

[0042] like Figures 2 to 7 As shown: the driving member 33 is provided with a slide rail 331 extending in the vertical direction and a bevel 332 connected to the slide rail 331, and the driving assembly 3 also includes a transmission rod 34 arranged below the driving member 33, the transmission rod 34 is arranged in a vertical state, and the transmission rod 34 can slide along the height direction of the test seat 1, and a rotatable second pulley 341 is arranged at the top of the transmission rod 34. When the transmission rod 34 slides along the height direction of the test seat 1, the transmission rod 34 can drive the second pulley 341 to slide along the bevel 332 and the slide rail 331, thereby driving the driving member 33 to move.

[0043] By providing a slide rail 331 extending in the vertical direction and a bevel 332 connected to the slide rail 331 on the driving member 33, and combining the cooperation between the transmission rod 34 and the second pulley 341, the device achieves smooth and accurate driving control. When the transmission rod 34 slides along the height direction of the test seat 1, the transmission rod 34 drives the second pulley 341 to first slide along the bevel 332 on the driving member 33, and then the second pulley 341 slides into the slide rail 331, and in this process, the driving member 33 is pushed to move along the width direction of the test seat 1. This design ensures the smooth movement of the driving member 33, reduces the error caused by unstable movement, and thus improves the accuracy of control.

[0044] When the second pulley 341 slides along the bevel 332, it drives the driving member 33 to slide along the width direction of the test seat 1. When the second pulley 341 slides into the slide rail 331, the slide rail 331 extends in the vertical direction, which limits the further movement of the driving member 33. At this time, the clamping force of the clamping arm 31 on the first pulley 32 will stop, ensuring that the slot 211 on the mounting plate 21 and the connector 11 on the test seat 1 will not continue to apply pressure after being plugged into place. Through this design, damage to the connector 11 caused by excessive pressure is avoided, and a stable locking effect is provided, ensuring that the connection between the slot 211 and the connector 11 can remain stable during a long aging test. Since the aging test usually lasts for more than 4 hours, this locking method effectively ensures the stable connection between the slot 211 and the connector 11 of the inverter 4 during the aging test, ensuring the accuracy and reliability of the test process.

[0045] The coordination of the bevel 332 and the slide rail 331 optimizes the power transmission path, reduces the resistance and unbalanced force that may occur in the traditional drive system, and improves the working efficiency of the transmission system. This design avoids excessive friction and ensures efficient and smooth power transmission. In addition, by integrating multiple functions into a few components, the structure of the drive system is simplified, the number of components is reduced, and the compactness and working efficiency of the device are improved. At the same time, the simplified design reduces the complexity of production and maintenance and reduces costs.

[0046] like Figures 2 to 5 , Figure 8 and Fig. 9 As shown: a positioning plate 351 is arranged between the transmission rods 34 below the two driving members 33, and the two transmission rods 34 both pass through the positioning plate 351 and slide with it; a frame 35 is arranged below the test seat 1, and a screw rod 3511 and a track 3512 extending along the width direction of the test seat 1 are arranged on the frame 35, the positioning plate 351 can be slidably arranged on the track 3512, and the positioning sleeve is arranged on the screw rod 3511 and threads with it.

[0047] By rotating the screw rod 3511, the positioning plate 351 that is threadedly matched with the screw rod 3511 can be driven to move, so that the positioning plate 351 can slide along the screw rod 3511. The movement of the positioning plate 351 drives the movement of the two transmission rods 34, thereby adjusting the position of the transmission rod 34 in the width direction of the test seat 1. By adjusting the position of the transmission rod 34, when the transmission rod 34 is lifted, the driving member 33 can be driven to move different distances, and the driving member 33 can be kept in a stable position after being locked. Through this adjustment process, the driving of the clamping arm 31 to the first pulley 32 can be accurately controlled, so as to accurately adjust the docking effect between the slot 211 on the mounting plate 21 and the joint 11 on the test seat 1, and ensure the stability and accuracy of the aging test.

[0048] By rotating the screw 3511 to adjust the positioning plate 351, the user can flexibly adjust the position of the transmission rod 34, so that the device can adapt to inverters 4 of different specifications or test requirements, providing higher operational flexibility. This adjustment mechanism greatly improves the versatility and adaptability of the device. The coordinated design of the positioning plate 351 and the screw 3511 ensures the accuracy of positioning and the stable movement of the transmission rod 34, and the self-locking property of the transmission through the screw 3511 enables the transmission rod 34 to maintain a stable position after being adjusted, avoiding unnecessary deviations, ensuring stability during long-term testing, and improving the reliability of the entire device. The simplified structural design also reduces the difficulty of maintenance, improves the ease of use and maintenance efficiency of the device.

[0049] like Figures 2 to 5 , Figure 8 and Fig. 9 As shown: a transmission plate 342 is arranged between the transmission rods 34 below the two driving members 33, the transmission plate 342 is fixedly connected to the bottom of the two transmission rods 34, a slide groove 3421 extending along the axial direction of the screw rod 3511 is arranged in the center of the transmission plate 342, a slider 3521 is arranged on the slide groove 3421, and a linear driver 352 that can drive the slider 3521 to move along the axial direction of the transmission rod 34 is arranged at the bottom of the frame 35.

[0050] The movement of the positioning plate 351 will drive the transmission rod 34 to change its position along the width direction of the test seat 1. Since the transmission plate 342 is fixedly connected to the bottom of the transmission rod 34, and the linear driver 352 cannot move with the transmission plate 342, the displacement of the transmission plate 342 will cause the slide 3421 to move accordingly. The slide 3421 compensates for the relative position difference between the transmission plate 342 and the linear driver 352 by sliding the slider 3521, thereby ensuring that the linear driver 352 can always effectively drive the movement of the transmission plate 342 by driving the slider 3521. Through this mechanism, the transmission plate 342 moves smoothly along the axial direction of the transmission rod 34, thereby driving the transmission rod 34 to lift upward, thereby realizing precise driving and adjustment of the transmission rod 34.

[0051] Due to the relative motion design of the slide 3421 and the slider 3521, the linear drive 352 can always maintain a stable and continuous driving state, avoiding jamming or uneven movement caused by position differences. This design ensures the stability of the lifting process of the transmission rod 34, and can ensure that consistent working results are continuously provided during long-term operation. The relative position adjustment between the transmission plate 342 and the linear drive 352 is more direct and effective. Since the need for complex parts is reduced, the overall structure is more compact, and the maintenance difficulty of the device is also reduced, thereby reducing the maintenance cost in long-term use. Through the above-mentioned precise adjustment and stable control, the device can maintain a high level of reliability and test accuracy in long-term high-precision operations such as aging tests. This not only improves the stability of the test results, but also enhances the long-term performance of the device. The linear drive 352 is preferably a cylinder.

[0052] like Figures 2 to 7 As shown: a guide rod 333 is provided on the end of the driving member 33 away from the mounting plate 21, a support plate 13 is provided on the end of the test seat 1 away from the mounting plate 21, a sleeve 3331 is provided on the support plate 13, the guide rod 333 is sleeved in the sleeve 3331 and an elastic member 3332 is provided in the sleeve 3331.

[0053] When the driving member 33 moves, the guide rod 333 slides along the axial direction of the sleeve 3331. The matching design of the guide rod 333 and the sleeve 3331 ensures that the driving member 33 is always on the correct path during the movement, avoiding unstable movement caused by offset or misalignment. The sliding function of the guide rod 333 can effectively guide the driving member 33, ensure the accuracy of the movement direction and position, and thus improve the overall stability of the device. When the guide rod 333 moves into the sleeve 3331, it will drive the elastic member 3332 to be squeezed. The elastic member 3332 provides the necessary elastic force for the guide rod 333. The elastic member 3332 can absorb part of the impact force and alleviate vibration or impact during the movement. This buffering effect not only reduces the wear of the device, but also extends the service life of the device. At the same time, when the clamping arm 31 needs to release the clamping of the first pulley 32, the elastic reset of the elastic member 3332 helps reset the driving member 33, so that the clamping arm 31 can quickly move away from the first pulley 32, so that the socket of the mounting plate 21 and the connector 11 of the test socket 1 are separated. This structure not only reduces the manufacturing cost, but also reduces the difficulty of maintenance, and further improves the economy and practicality of the device.

[0054] like Figures 2 to 7 As shown: the sleeve 3331 and the support plate 13 are connected via threads.

[0055] The threaded connection between the sleeve 3331 and the support plate 13 ensures stability and firmness between the two. The threaded connection provides a tight connection, so that the sleeve 3331 can effectively maintain its position during use, avoiding looseness or deviation, thereby enhancing the structural stability of the overall device. The position of the sleeve 3331 on the support plate 13 can be changed by the threaded connection, thereby adjusting the position of the guide rod 333, thereby changing the initial position of the drive member 33 in the width direction of the test seat 1, thereby changing the clamping angle of the two clamping arms 31 in the initial state, thereby improving the adaptability of the device.

[0056] like Figures 2 to 5 As shown: two limit blocks 22 are arranged on one end of the mounting plate 21 close to the test seat 1, and the two limit blocks 22 are respectively fixedly connected to the two ends of the mounting plate 21 in the length direction, and the two limit blocks 22 are made of elastic materials.

[0057] The main function of the limit block 22 is to ensure that the mounting plate 21 and the test socket 1 maintain an appropriate distance, to prevent the mounting plate 21 from excessively moving and causing the slot 211 and the connector 11 to come into too tight contact, thereby preventing damage caused by excessive pressure or improper plugging. By effectively limiting the minimum distance between the two, the structural integrity of the slot 211 and the connector 11 is protected, ensuring that the device can be connected and tested in a stable state. The design of the limit block 22 effectively limits the excessive movement of the mounting plate 21 and ensures the docking stability of the slot 211 and the connector 11. When performing aging tests, a stable plug connection is crucial to the accuracy of the test results.

[0058] The simple design of the stopper 22 reduces the complexity of the device and reduces the cost of the traditional protection system. Its elastic material not only plays a protective role, but also reduces the difficulty and frequency of maintenance, and reduces the cost of repair and replacement due to damage.

[0059] like Figures 1 to 4 and Fig.10 As shown, a plurality of positioning grooves 23 for positioning the inverter 4 are arranged at the bottom of the mounting base 2, a slidable positioning block 231 is arranged on the positioning groove 23, and a fixing member 232 which is threadedly matched with the positioning block 231 is arranged on the positioning block 231.

[0060] The design of the positioning groove 23 and the positioning block 231 can ensure the accurate position of the inverter 4 in the mounting base 2. Through the guiding effect of the positioning groove 23, the positioning block 231 can slide on the positioning groove 23 and fix the position of the inverter 4, avoiding instability or test errors caused by position offset of the inverter 4 during the aging test. This design ensures that the inverter 4 always remains in the correct fixed position during the test, providing a precise test environment.

[0061] The positioning block 231 adopts a sliding design, so that the user can adjust the position of the inverter 4 according to the size and requirements of the inverter 4. Combined with the setting of the positioning slot 23, the user can easily adjust the position of the positioning block 231 to adapt to inverters 4 of different models or sizes, providing flexibility and diverse adaptation solutions, and enhancing the versatility of the device. By providing a fixing member 232 that is threadedly matched with the positioning block 231, this threaded connection design can ensure that the positioning block 231 can be firmly fixed in the desired position after sliding. The threaded matching provides a solid locking force, which effectively prevents the positioning block 231 from loosening or shifting during operation, ensuring the stability and accuracy of the inverter 4 during the entire test process. This simple fixing method makes the operation more intuitive and convenient, reduces the operation time and complexity, and improves the efficiency of the test process.

[0062] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
