For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0028] Example 1 See also Figures 1 to 9 , the present invention provides a solar cell assembly static pressure test device, comprising a box body 1, a test cavity 1-1 for carrying a solar panel to be tested is arranged in the middle of the upper surface of the box body 1; The box body 1 is connected to the box cover 1-2 via a hinge mechanism 2, and the box cover 1-2 is provided with a test unit 1-3 for static pressure testing of the solar panel; The box body 1 is also provided with a fastening mechanism 3 for fixing the box cover 1 - 2 , and a driving unit 4 for driving the fastening mechanism 3 and the hinge mechanism 2 to work.

[0029] The hinge mechanism 2 includes slide grooves 2-1 opened on both sides of the box body 1, and an arc-shaped guide groove 2-2 is opened at the upper end of each slide groove 2-1. The center of the guide groove 2-2 is coaxial with the upper end of the slide groove 2-1, and a lifting rod 2-3 is slidably arranged in the slide groove 2-1; Two slide rods are fixedly arranged at one end of the lifting rod 2-3, and the two slide rods slide in the slide groove 2-1, and the distance between the two slide rods corresponds to the radius of the guide groove 2-2; The lifting rod 2-3 is Z-shaped, and a mounting plate 2-4 is fixedly arranged at one end of the lifting rod 2-3 away from the slide rod, and a box cover 1-2 is fixedly arranged on the mounting plate 2-4.

[0030] The end of the lifting rod 2-3 away from the mounting plate 2-4 is rotatably provided with a connecting rod 2-5; A swing arm 2-6 is rotatably arranged on the box body 1, and a movable end of the swing arm 2-6 is rotatably connected to one end of the connecting rod 2-5, and the rotating end of the swing arm 2-6 informs a fixed driven gear 2-7, and one side of the driven gear 2-7 meshes with the driving gear 2-8; When the driving gear 2-8 rotates, the driving gear 2-8 drives the driven gear 2-7 to rotate, and the driven gear 2-7 drives the connecting rod 2-5 to move under the action of the swing arm 2-6. When the connecting rod 2-5 moves, the state of the lifting rod 2-3 is driven to change; When the swing arm 2-6 rotates upward, the swing arm 2-6 pushes the lifting rod 2-3 to move upward under the action of the connecting rod 2-5. When a sliding rod at the upper end of the lifting rod 2-3 moves to the upper end of the slide groove 2-1, as the connecting rod 2-5 continues to move, it drives the other sliding rod to move along the curved guide groove 2-2. At this time, the two sliding rods are in a horizontal state. Under the action of the lifting rod 2-3, the box cover 1-2 is placed vertically, and the test cavity 1-1 is fully exposed, which is convenient for taking and placing the battery assembly 5; the operator can easily put the battery assembly 5 to be tested into the test cavity 1-1, or take out the battery assembly 5 after the test, and the whole process is efficient and convenient; at the same time, the vertically placed box cover 1-2 does not take up too much space, providing greater freedom for operation; Under the action of the hinge mechanism 2, when the box cover 1-2 is opened, the box cover 1-2 first moves upward a certain distance and then turns over. Conversely, when the box cover 1-2 is closed, the box cover 1-2 first turns over to the top of the box body 1 and then moves downward until the box cover 1-2 is tightly attached to the upper end of the box body 1. When the swing arm 2-6 rotates downward, the swing arm 2-6 drives the lifting rod 2-3 to move downward under the action of the connecting rod 2-5, and one end of the lifting rod 2-3 first moves along the curved guide groove 2-2, so that the two sliding rods are in a vertical state, and with the continuous movement of the swing arm 2-6, the two sliding rods are moved to the lower part of the slide groove 2-1, and the box cover 1-2 can tightly cover the test cavity 1-1 at this time; this design ensures that the test cavity 1-1 is in a closed state during the test, avoiding external factors from interfering with the test results; the tight closure of the box cover 1-2 can effectively prevent dust, moisture, etc. from entering the test cavity 1-1, ensuring the stability and reliability of the test environment; in addition, good sealing performance also helps to improve the precision and accuracy of the test, providing a more reliable basis for the performance evaluation of the battery assembly 5.

[0031] At the same time, the sealed box cover 1-2 can prevent the battery assembly 5 from breaking during testing, thereby reducing the risk of accidental injury to personnel; further, the battery assembly can be tested for air tightness at a later stage, and a certain pressure can be applied to the battery assembly through gas, thereby achieving static pressure testing of the battery assembly.

[0032] Furthermore, two spring pins are provided at the upper end of the slide groove 2-1. When the slide rod moves upward, one of the slide rods moves to the upper end of the spring pin. When the swing arm 2-6 rotates downward, under the action of the spring pin, one end of the lifting rod 2-3 first moves along the curved guide groove 2-2, so that the two slide rods are in a vertical state. At this time, the box cover 1-2 is placed horizontally. With the continuous movement of the swing arm 2-6, the lifting rod 2-3 will continue to move downward, and both slide rods move to the lower part of the slide groove 2-1. At this time, the box cover 1-2 can tightly cover the test cavity 1-1.

[0033] The driving unit 4 includes a transmission rod 4-1 fixedly connected to two driving gears 2-8; An output bevel gear 4-2 is fixedly arranged in the middle of the transmission rod 4-1, one side of the output bevel gear 4-2 is meshed with an input bevel gear 4-3, the input bevel gear 4-3 is rotationally connected to the housing 1, a wrench 4-4 is fixedly arranged on the input bevel gear 4-3, and the wrench 4-4 extends to the outside of the housing 1.

[0034] When preparing to perform a static pressure test on the solar cell assembly 5, the operator first places the cell assembly 5 to be tested in the test cavity 1-1, and the operator rotates the wrench 4-4 to drive the input bevel gear 4-3 fixedly connected thereto to rotate. Since the input bevel gear 4-3 is meshed with the output bevel gear 4-2, the rotation of the input bevel gear 4-3 will cause the output bevel gear 4-2 to rotate accordingly. The output bevel gear 4-2 is fixed to the middle part of the transmission rod 4-1, and its rotation will drive the transmission rod 4-1 to rotate; The rotation of the transmission rod 4-1 causes the two driving gears 2-8 to rotate synchronously; the driving gear 2-8 drives the driven gear 2-7 to rotate, and the driven gear 2-7 drives the connecting rod 2-5 to move under the action of the swing arm 2-6. When the connecting rod 2-5 moves, the state of the lifting rod 2-3 is driven to change.

[0035] The fastening mechanism 3 includes a control board 3-1 located in the middle of the box body 1, and a clamping arm 3-2 is rotatably provided at each of the four corners of the control board 3-1. The lower end of each clamping arm 3-2 is rotatably connected to the control board 3-1, and a through slot 3-3 is provided in the middle of the clamping arm 3-2. The through slot 3-3 corresponds to the shape of the clamping arm 3-2, and the clamping arm 3-2 is slidably connected to the box body 1 through the through slot 3-3; A clamping plate 3-4 is fixedly arranged on the upper end of the clamping arm 3-2.

[0036] The clamping arm 3-2 is V-shaped, and the angle between the two ends of the clamping arm 3-2 is an obtuse angle. The upper end of the clamping arm 3-2 is a vertical portion, and the lower end is an inclined portion. A rotating shaft is set on the box body 1, and the box body 1 slides with the through slot 3-3 through the rotating shaft. When the control board 3-1 moves upward, the clamping arm 3-2 moves upward under the action of the vertical portion of the through slot 3-3, and the clamping plate 3-4 is separated from the clamping of the box cover 1-2. When the rotating shaft is located at the inclined portion of the through slot 3-3, as the control board 3-1 moves upward, the upper end of the clamping arm 3-2 flips to the side away from the control board 3-1, so as to facilitate the opening of the box cover 1-2.

[0037] A driving bevel gear 3-5 is coaxially fixedly arranged at both ends of the rod body of the transmission rod 4-1, and the driving bevel gear 3-5 is an incomplete gear; A through hole is respectively formed at the two ends of the control plate 3-1, and an adjusting rod 3-7 is rotatably arranged in the through hole. A driven bevel gear 3-6 is fixedly arranged at the upper end of the adjusting rod 3-7, and the driven bevel gear 3-6 is meshed with the teeth of the driving bevel gear 3-5; A plurality of spiral grooves 3-8 are provided on the rod body of the adjusting rod 3-7, and a plurality of protrusions are fixedly arranged on the through hole, and each protrusion slides in one of the spiral grooves 3-8 respectively.

[0038] The operator rotates the wrench 4-4 to drive the input bevel gear 4-3 fixedly connected thereto to rotate. Since the input bevel gear 4-3 is meshed with the output bevel gear 4-2, the rotation of the input bevel gear 4-3 will cause the output bevel gear 4-2 to rotate accordingly. The output bevel gear 4-2 is fixed to the middle part of the transmission rod 4-1, and its rotation will drive the transmission rod 4-1 to rotate; The driving bevel gears 3-5 at both ends of the transmission rod 4-1 rotate accordingly. Since the driving bevel gear 3-5 is an incomplete gear, during its rotation, when the toothed part contacts the driven bevel gear 3-6, it drives the driven bevel gear 3-6 to rotate. The driven bevel gear 3-6 is fixed to the upper end of the adjusting rod 3-7. The rotation of the driven bevel gear 3-6 causes the adjusting rod 3-7 to rotate in the through hole. The spiral groove 3-8 on the rod body of the adjusting rod 3-7 interacts with the protrusion on the through hole. As the adjusting rod 3-7 rotates, the protrusion slides in the groove, so that the adjusting rod 3-7 produces an up and down displacement while rotating, thereby driving the control board 3-1 to move up and down, thereby realizing the position adjustment of the clamping arm 3-2 to meet the clamping requirements of the box cover 1-2 during the test.

[0039] When the user wants to open the box cover 1-2, the user controls the expansion of the clamp arm 3-2 and the opening of the box cover 1-2 while turning the wrench 4-4. When the clamp arm 3-2 is expanded, the toothed portion of the active bevel gear 3-5 is separated from the driven bevel gear 3-6, and the clamp arm 3-2 remains in the expanded state until the box cover 1-2 is fully expanded. When the box cover 1-2 is to be closed, the user rotates the wrench 4-4 in the opposite direction. During the closing process of the box cover 1-2, when the toothed part contacts the driven bevel gear 3-6, the driven bevel gear 3-6 is driven to rotate, and under the action of the adjusting rod 3-7, the control board 3-1 is driven to move up and down, thereby adjusting the position of the clamping arm 3-2 to meet the clamping requirements of the box cover 1-2 during the test.

[0040] A locking hook 4-5 is rotatably provided at each of the two ends of the box body 1. When the wrench 4-4 moves to one end of the box body 1, the wrench 4-4 is detachably connected to one of the locking hooks 4-5.

[0041] When the box cover 1-2 needs to be opened or closed, the operator turns the wrench 4-4 located on the outside of the box body 1. During the operation, when the wrench 4-4 moves to one end of the box body 1, the wrench 4-4 can be detachably connected to the locking hook 4-5 located at the end.

[0042] This connection can fix the position of the wrench 4-4 and prevent the wrench 4-4 from rotating at will when not needed, thereby avoiding unnecessary interference with the normal operation of the test device, and can limit the position of the box cover 1-2 to ensure that the box cover 1-2 can fit tightly against the box body 1 when closed, and maintain the sealing of the test cavity 1-1. When the wrench 4-4 is connected to the locking hook 4-5, the restraining force it generates will be transmitted to the fastening mechanism 3 related to the box cover 1-2, so that the box cover 1-2 is more firmly in the closed position, preventing the box cover 1-2 from accidentally opening due to external vibration or other factors during the test, thereby affecting the accuracy and safety of the test; at the same time, when the wrench 4-4 needs to be used for operation again, the wrench 4-4 can be easily removed from the locking hook 4-5, and the corresponding adjustment action can be continued.

[0043] A plurality of test holes are provided in the middle of the box cover 1-2, a test unit 1-3 is arranged in one of the test holes, and the other test holes are blocked by blocking blocks 1-5; The test unit 1-3 includes an electric push rod 1-4 detachably connected to the box cover 1-2, and a detachable test head at the movable end of the electric push rod 1-4.

[0044] Furthermore, the test head can be a point test head or a plate test head. The point test head can perform point tests on the battery assembly 5. By replacing different test holes of the electric push rods 1-4, different positions of the battery assembly 5 can be tested, thereby simulating the gravity impact of hail falling on the photovoltaic panel and testing the physical impact load of hail on the photovoltaic panel. By performing point tests at different positions, the fragility and strength differences of the photovoltaic panel at different positions can be fully understood, providing an important basis for optimizing the design and installation of the photovoltaic panel. The plate-shaped test head can perform an overall test on the battery assembly 5 and can cover a larger test area at one time, comprehensively evaluate the overall performance of the battery assembly 5, and simulate the load condition of the battery assembly 5 such as snow cover. By applying uniform pressure to the battery assembly 5, the plate-shaped test head can detect the performance changes of the battery assembly 5 under the overall load, including the stability of the output power, the integrity of the structure, etc.; this testing method is helpful to evaluate the reliability and durability of the battery assembly 5 in various harsh environments, and provide guarantee for the long-term stable operation of the photovoltaic system.

[0045] Furthermore, a pressure sensor is provided on the test head. When the point test head performs a point test on the battery assembly 5, the pressure sensor can accurately measure the instantaneous pressure value during the simulated hail impact. This can not only help researchers to more accurately understand the specific impact strength of hail on different positions of the photovoltaic panel, but also provide quantitative data support for evaluating the impact resistance of the photovoltaic panel. By analyzing the hail impact test data at different positions and with different intensities, the material and structural design of the photovoltaic panel can be improved in a targeted manner to enhance its ability to resist hail impact.

[0046] When the battery assembly 5 is tested as a whole using a plate-shaped test head, the pressure sensor can monitor in real time the pressure distribution under load conditions such as simulated snow cover; this helps to fully understand the pressure differences at various parts of the battery assembly 5 under the overall load, thereby evaluating its stability and reliability under different load conditions; at the same time, the data from the pressure sensor can also be used to optimize the loading method and force control of the plate-shaped test head, to ensure the accuracy and repeatability of the test results; in short, setting a pressure sensor on the test head provides a more accurate and scientific testing method for the static pressure test device of the solar cell assembly.

[0047] When the present invention is used, when preparing to perform a static pressure test on a solar cell assembly 5, an operator first places the battery assembly 5 to be tested in the test cavity 1-1, and the operator rotates the wrench 4-4 so that the box cover 1-2 tightly covers the test cavity 1-1; When the toothed part of the active bevel gear 3-5 contacts the driven bevel gear 3-6, it drives the driven bevel gear 3-6 to rotate, and under the action of the adjusting rod 3-7, it drives the control board 3-1 to move up and down, thereby adjusting the position of the clamping arm 3-2 to meet the clamping requirements of the box cover 1-2 during the test.

[0048] According to the test requirements, select the appropriate test head. The point test head is used to simulate the point impact of hail. The electric push rod can switch positions to test different points of the battery component. The plate test head simulates large-area loads such as snow to test the battery component as a whole. The two combined with pressure sensors provide a basis for evaluating the performance of battery components.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
