For those skilled in the art, the specific meanings of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0040] Energy storage products must undergo testing before they are released to the market, such as IEC62477 testing, to ensure that their electrical performance, mechanical performance, environmental adaptability, safety performance, and other aspects meet preset standards. Mechanical performance testing includes vibration testing, which achieves its testing purpose by simulating the operating conditions of container transportation.

[0041] Energy storage products include control cabinets, which require vibration testing. Existing vibration testing requires a vibration table. By mounting the control cabinet on the table, the table vibrates the cabinet, simulating the operating conditions of container transportation. Existing control cabinets are typically mounted on a vibration table by connecting the bottom of the control cabinet to the tabletop with bolts or other fasteners.

[0042] However, in some situations, such as when the control cabinet is too high, the control cabinet is prone to swing with the vibration of the table, and may even resonate, affecting the test effect of the control cabinet.

[0043] In response to the above problems, an embodiment of the present application provides a vibration testing tool. By arranging a first mounting member, a second mounting member, and a connecting frame on the vibration table to form a accommodating cavity for fixing the control cabinet, the vibration table, the first mounting member, the second mounting member, the connecting frame, and the control cabinet are connected and fixed as a whole. In this way, the actual installation state of the control cabinet in the container is restored on the vibration table, and the overall vibration of the control cabinet is achieved when the vibration test is performed on the vibration table to achieve the test purpose, avoid the control cabinet from swinging or resonating with the vibration of the vibration table, and ensure the accuracy of the vibration test results of the control cabinet.

[0044] The embodiments of the present application are described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Reference Figures 1 to 4 As shown, a vibration testing tool provided in an embodiment of the present application includes a first mounting member 100 , a second mounting member 200 and a connecting frame 300 .

[0046] Among them, the first mounting member 100 is used to be installed on the vibration table 10, and the first mounting member 100 includes a first mounting portion 111, which is used to connect to the control cabinet 20; the second mounting member 200 is used to be connected to the upper part of the control cabinet 20; the connecting frame 300 is used to connect the second mounting member 200 and the vibration table 10; the second mounting member 200 is configured to form a accommodating cavity for accommodating the control cabinet 20 with the first mounting member 100 and the connecting frame 300.

[0047] By fixing the first mounting member 100 on the vibration table 10, the control cabinet 20 is then placed on the first mounting member 100, the control cabinet 20 is connected to the first mounting portion 111 by bolts, etc., and the second mounting member 200 is connected to the upper part of the control cabinet 20, thereby achieving the overall connection and fixation of the vibration table 10, the first mounting member 100, the second mounting member 200, the connecting frame 300, and the control cabinet 20. In this way, the actual installation state of the control cabinet 20 in the container is restored on the vibration table 10, and the overall vibration of the control cabinet 20 is achieved when the vibration table 10 is subjected to a vibration test, so as to achieve the test purpose, avoid the control cabinet 20 from swinging or resonating with the vibration of the vibration table 10, and ensure the accuracy of the vibration test results of the control cabinet 20.

[0048] It should be noted that the vibration test tooling provided in the embodiment of the present application is designed with the assistance of simulation software, and its structural strength and seismic resistance are close to those of a container. In this way, when the vibration table 10 is operating, the working conditions of the control cabinet 20 during transportation in the container can be more realistically simulated, and the real vibration test data of the control cabinet 20 can be obtained.

[0049] In some embodiments, the first mounting member 100 includes at least one mounting plate 110, the mounting plate 110 is used to be laid on the vibration table 10, the first mounting portion 111 is provided on the mounting plate 110, and the first mounting portion 111 is provided with multiple fixing members to connect the mounting plate 110 and the vibration table 10 as well as the mounting plate 110 and the control cabinet 20.

[0050] Furthermore, a first fixing hole is provided on the vibration table 10, a second fixing hole is provided at the bottom end of the control cabinet 20, a first positioning hole is provided on the first mounting portion 111 corresponding to the first fixing hole, and a second positioning hole is provided on the first mounting portion 111 corresponding to the second fixing hole; the design of the first positioning hole and the second positioning hole respectively takes into account the size and installation requirements of the first fixing hole and the second fixing hole, ensuring smooth fastening between the vibration table 10, the first mounting part 100, and the control cabinet 20.

[0051] The second positioning holes correspond to the second fixing holes of various types of control cabinets 20 , so that the fixing of multiple types of control cabinets 20 can be compatible.

[0052] The fixing piece connects the mounting plate 110 and the vibration table 10 through the first fixing hole and the first positioning hole, and the fixing piece connects the mounting plate 110 and the control cabinet 20 through the second fixing hole and the second positioning hole. In this way, the mounting plate 110 serves as a connection medium between the vibration table 10 and the control cabinet 20 to achieve the connection and fixation between the vibration table 10 and the control cabinet 20, avoiding the installation difficulty caused by the incompatibility of the hole positions of the control cabinet 20 and the vibration table 10.

[0053] For example, four mounting plates 110 may be provided, and the four mounting plates 110 are arranged in pairs along the length direction and the width direction of the bottom surface of the control cabinet 20 .

[0054] For example, the mounting plate 110 can be compatible with the control cabinet 20 with a bottom length or width ranging from 400 to 1000 m.

[0055] In some embodiments, as Figure 2 and Figure 3As shown, the second mounting member 200 includes a fixed beam 210 and a connecting plate 220. The fixed beam 210 is provided with at least one second mounting portion 211, and the second mounting portion 211 is used to connect to the upper part of the control cabinet 20. The connecting plate 220 is provided with a plurality of mounting holes 221, and at least one bolt is provided in the mounting hole 221 to respectively connect the fixed beam 210 and the connecting frame 300 through the plurality of mounting holes 221.

[0056] The fixed beam 210 is the main supporting part of the second mounting member 200. At least one second mounting portion 211 is provided on the fixed beam 210. These mounting portions can be clamps, bolt holes or other forms of connectors to ensure a stable connection with the upper part of the control cabinet 20; the connecting plate 220 is used to connect the fixed beam 210 and the connecting frame 300 to ensure the stability and reliability of the entire tooling structure.

[0057] For example, the second mounting member 200 may be formed of a 50×50 cold-rolled square steel pipe.

[0058] In some examples, a third fixing hole is opened at the top of the control cabinet 20, and a third positioning hole is opened at the second mounting portion 211 corresponding to the third fixing hole. Bolts are connected between the top of the control cabinet 20 and the second mounting member 200 through the third fixing hole and the third positioning hole.

[0059] Furthermore, the third positioning hole is an adjustment hole, and its adjustment direction is toward any horizontal direction, so as to adjust the installation position of the third positioning hole and the third fixing hole according to actual needs, while avoiding dimensional tolerance and ensuring the adaptability between the two.

[0060] In some embodiments, the mounting hole 221 includes a first hole 2211 . There are multiple first holes 2211 , which are spaced apart. The first holes 2211 are used to connect to the fixed beam 210 . The multiple first holes 2211 are arranged along the height direction of the control cabinet 20 .

[0061] Multiple first holes 2211 are arranged along the height direction of the control cabinet 20, so that the first holes 2211 form a vertical hole column on the connecting plate 220, so that the height of the fixed beam 210 can be adjusted by selecting different hole positions. In this way, the adaptability of the vibration test tooling to control cabinets 20 of different heights can be ensured.

[0062] Furthermore, the spacing between each pair of first holes 2211 should be determined based on the required height adjustment accuracy and stability. This spacing should ensure that, when connected, the fixed beam 210 can be stably supported at the selected hole location and withstand the loads during the vibration test. For example, the spacing between adjacent first holes 2211 can be 100 mm, which is compatible with control cabinets 20 with heights of 2200 mm and 2300 mm for vibration testing.

[0063] Furthermore, the first hole 2211 is an adjustment hole, and the adjustment direction of the first hole 2211 is set along the height direction of the control cabinet 20. In this way, the position of the bolt can be adjusted in the first hole 2211 so that it is connected to the fixed beam 210 accordingly, avoiding dimensional tolerance and ensuring the adaptability between the two.

[0064] In some embodiments, the fixed beam 210 includes a top beam 212 and multiple reinforcing beams 213. The top beam 212 is the primary support for the fixed beam 210, while the reinforcing beams 213 are auxiliary support structures for the fixed beam 210, enhancing the stability of the top beam 212. At least two reinforcing beams 213 are fixed to each other at an angle to form a reinforcing frame, which is disposed at the ends of the top beam 212 and connected to the multiple first holes 2211. The height of the fixed beam 210 can be adjusted and fixed by passing bolts through the first holes 2211, which are aligned with the height of the control cabinet 20.

[0065] Furthermore, the hole array formed by the first hole 2211 on the connecting plate 220 may be provided with multiple rows, and the reinforcement frame formed by the two reinforcement beams 213 at an angle to each other is a triangular structure. In some examples, the reinforcement frame may have holes at its three end corners respectively connected to the first hole 2211, thereby improving the connection stability between the fixed beam 210 and the connecting plate 220. In this way, not only the stability and bearing capacity of the overall structure are enhanced, but also the flexibility and adjustability are increased, providing a reliable support structure for vibration testing.

[0066] In addition, the mounting hole 221 also includes a plurality of second holes 2212, which are arranged at intervals, and the extension direction of the plurality of second holes 2212 is at a preset angle to the extension direction of the plurality of first holes 2211; the connecting frame 300 is provided with a plurality of connecting holes, which are arranged at intervals, and are suitable for connecting the second holes 2212 and the connecting holes by bolts.

[0067] The second hole 2212 is used to adjust the installation position of the connecting plate 220 on the connecting frame 300 to improve the connection stability between the connecting plate 220 and the connecting frame 300.

[0068] In some examples, the number of connecting holes is greater than the number of second holes 2212, so that the position of the connecting plate 220 on the connecting frame 300 is adjustable; further, the number of connecting holes is a multiple of the number of second holes 2212, so that more than one connecting plate 220 can be installed on the connecting frame 300, and accordingly, more than one second mounting member 200 can be installed on the connecting frame 300, that is, more than one control cabinet 20 can be installed on the connecting frame 300 accordingly, and since the height of the second mounting member 200 is adjustable, there is no limit on the height of the tested control cabinet 20, thereby improving the efficiency of the vibration test.

[0069] Furthermore, the connecting hole is an adjustment hole, and the adjustment direction of the adjustment hole is horizontal, which avoids the dimensional tolerance between the second hole 2212 and ensures the adaptability between the connecting plate 220 and the connecting frame 300.

[0070] For example, the shape of the adjustment hole can be designed to be elliptical, polygonal, etc. according to actual needs.

[0071] In some embodiments, two connecting frames 300 are provided, one end of the two connecting frames 300 is fixed to each other, and the two connecting frames 300 are at an angle to each other; one connecting frame 300 is connected to the vibration table 10, and the other connecting frame 300 is connected to the second mounting member 200.

[0072] In this way, the two connecting frames 300 form a stable base; the two connecting frames 300 are at an angle to each other, and this angle can be determined according to specific test requirements and structural stability. For example, the angle is 90 degrees.

[0073] Furthermore, the connecting frame 300 includes a plurality of fixing frames, which are interconnected to form an integral structure. By adjusting the number and connection method of the fixing frames, the connecting frame 300 can reach a preset length and width. Typically, the fixing frame is rectangular in shape. Furthermore, triangular reinforcement plates 310 are welded at the four corners of each fixing frame to enhance the overall strength and shock resistance.

[0074] For example, the fixing frame may be composed of a 50×50 cold-rolled square steel tube.

[0075] In some examples, two connecting frames 300 may be respectively provided on both sides of the control cabinet 20 , and correspondingly, both ends of the second mounting member 200 are respectively connected to the two connecting frames 300 .

[0076] The vibration test fixture provided in the embodiment of the present application also includes at least one set of inclined beams 400, which connect the two connecting frames 300 to form a triangular support portion. The triangular support portion has good stability and load-bearing capacity, can effectively disperse the load and prevent structural deformation, and improve the overall stability and seismic resistance.

[0077] Furthermore, the inclined beam frame 400 includes at least one inclined beam, one end of which is connected to a connecting frame 300, and the other end is connected to another connecting frame 300, or is interconnected with other inclined beams to form a stable triangular structure to enhance the overall stability of the tooling.

[0078] A vibration testing fixture provided in an embodiment of the present application further includes at least one connecting beam 500. At least two groups of connecting frames 300 are provided for every two connecting frames 300. Each group of connecting frames 300 is connected to the ends of the second mounting member 200, and the connecting beam 500 connects two adjacent groups of connecting frames 300. The connecting beam 500 connects the two adjacent groups of connecting frames 300, enhancing the stability and load-bearing capacity of the overall structure, making the vibration resistance of the entire fixture close to that of a container, thereby simulating the actual installation conditions of the control cabinet 20 for vibration testing.

[0079] For example, the connecting beam 500 may be formed of a 50×50 cold-rolled square steel pipe.
