[0028] Please refer to Figures 1 to 4 This utility model provides a power module impact vibration test fixture, comprising:

[0029] Base 1, with multiple product slots 11 for placing power modules 4;

[0030] Multiple positioning components 2 are detachably connected to the base 1, and the multiple positioning components 2 are respectively set above the multiple product slots 11;

[0031] Multiple connecting plates 3, each of which is detachably connected to multiple positioning parts 2.

[0032] In this embodiment, the power module impact vibration test fixture includes a base 1 with multiple product slots 11 for placing power modules 4. The shape of the product slots 11 matches the shape of the power modules 4. The multiple product slots 11 allow the fixture to simultaneously hold multiple individual power modules 4 for testing, thereby reducing vibration time and improving the efficiency of the vibration test. In this embodiment, the base 1 has 36 product slots 11. The number of product slots 11 is not limited and can be set according to actual production needs.

[0033] The plurality of product slots 11 include at least two types of first and second product slots corresponding to the placement states of the power modules 4. That is, the plurality of product slots 11 include first and second product slots of different shapes, but the different shapes of the first and second product slots correspond to two placement states of the power modules 4, making it easier to place the power modules 4 into the product slots 11 and saving time in placing multiple power modules 4 into the product slots 11. The specific number of different product slots 11 adapted to the placement states of the power modules 4 is not limited here; it is set according to actual production needs. In this embodiment, two types are specifically provided. The power module 4 in this embodiment is a general-purpose DC-DC power module, converting 9V to 36V to 5V, 12V, and 15V, and is used in civilian and industrial fields, specifically including home appliances, machine tools, and automobiles.

[0034] Specifically, multiple positioning elements 2 are detachably connected to the base 1, and each positioning element 2 is correspondingly positioned above each product slot 11. This allows the power module 4 placed in the product slot 11 to be fixed to the base 1, better limiting the position of the power module 4. This ensures the vibration test effect during fixture vibration, better simulating the installed state of the power module 4 and meeting the vibration test requirements of the power module 4. The number of positioning elements 2 corresponds to the number of product slots 11, with one positioning element 2 positioned above each product slot 11. This fixes the power module 4 between the product slot 11 and the positioning element 2, better limiting the position of the power module 4 and preventing it from shaking during vibration, thus preventing damage to the product during the vibration test.

[0035] The base 1 and the positioning component 2 are made of P20 steel, and the base 1 is designed to be elongated oval in shape so as to allow for the opening of multiple product slots 11.

[0036] Specifically, the power module 4 impact vibration test fixture also includes multiple connecting plates 3, each of which is detachably connected to multiple positioning parts 2. This allows the operator to place the power module 4 in the product slot 11 without having to search for and connect each positioning part 2 one by one. Instead, the connecting plate 3 with multiple positioning parts 2 is set on the base 1, and the multiple positioning parts 2 connected to the connecting plate 3 are connected to the base 1. This makes it convenient for the operator to disassemble the fixture, solving the problem of the existing impact vibration fixtures requiring multiple disassemblies and installations, which is troublesome.

[0037] The connecting plate 3 is made of polyurethane (PU).

[0038] Furthermore, each positioning member 2 is provided with at least two first through holes 21, which are located at both ends of the positioning member 2, and are detachably connected to the base 1 via the first connector 5.

[0039] In this embodiment, each positioning member 2 is provided with at least two first through holes 21, and the at least two first through holes 21 are located at both ends of the positioning member 2, so that the positioning member 2 can be easily fixed to the base 1 through the two first through holes 21. Specifically, the positioning member 2 is detachably connected to the base 1 by at least two first connecting members 5 passing through the two first through holes 21 on the positioning member 2. The number of first connecting members 5 is the same as the number of first through holes 21 on the multiple positioning members 2.

[0040] In this embodiment, the first connector 5 is a bolt, and its specific type in this embodiment is M3×16.

[0041] Furthermore, each positioning member 2 is provided with a second through hole 22, which is located between two first through holes 21. Each connecting plate 3 is also provided with multiple third through holes 31 that are adapted to the second through holes 22. The second connecting member 6 passes through the third through holes 31 and the second through holes 22 in sequence so that the connecting plate 3 and the multiple positioning members 2 can be detachably connected.

[0042] In this embodiment, each positioning member 2 is further provided with a second through hole 22, which is located between two first through holes 21, i.e., the second through hole 22 is located in the middle of the positioning member 2. The second through hole 22 is used to detachably connect the positioning member 2 and the connecting plate 3. The positioning member 2 and the connecting plate 3 are detachably connected by a second connecting member 6 passing through the second through hole 22 and the third through hole 31, so that one connecting plate 3 can connect multiple positioning members 2, which facilitates the operator to disassemble the fixture. Each connecting plate 3 is connected to multiple positioning members 2 respectively.

[0043] The second connecting member 6 is a bolt, and in this embodiment, the specific type is M3×8.

[0044] Furthermore, each positioning element 2 is in the shape of an arched cuboid, and the plurality of positioning elements 2 include a plurality of first positioning elements 2 and second positioning elements 2 of different sizes.

[0045] In this embodiment, each positioning element 2 is a rectangular prism with an arched structure and is positioned above the product slot 11 to limit the power module 4 inside the product slot 11 and prevent the power module 4 from shaking during vibration, so as not to affect the test results.

[0046] Specifically, in this embodiment, the positioning element 2 mainly includes a first positioning element and a second positioning element of two different sizes. Since the product slot 11 has two types of slots—a first product slot and a second product slot—that are compatible with the placement of the power module 4, it is equipped with first and second positioning elements that are compatible with both the first and second product slots. The specific number of different sizes of positioning elements 2 is not limited here; different sizes of positioning elements 2 correspond to different shapes of product slots 11.

[0047] Furthermore, the length of the positioning component 2 ranges from 25-32mm; the width ranges from 6-8mm; and the height ranges from 9-12mm. Specifically, the first positioning component has a length of 26.7mm, a width of 7mm, and a height of 10.8mm; the second positioning component has a length of 30.8mm, a width of 7mm, and a height of 10.8mm. The specific dimensions of the positioning component 2 are not limited here and are set according to actual production needs.

[0048] Furthermore, each connecting plate 3 is cuboid in shape, and the multiple connecting plates 3 include multiple first connecting plates, second connecting plates and third connecting plates of different sizes.

[0049] In this embodiment, each connecting plate 3 is shaped like a cuboid to allow it to connect as many positioning components 2 as possible. The connecting plate 3 includes three different sizes: a first connecting plate, a second connecting plate, and a third connecting plate, to fit the shape of the base 1, thus facilitating the assembly of the power module 4. The specific number of different sizes of connecting plates 3 is not limited and is determined according to actual production needs; in this embodiment, three different sizes of connecting plates 3 are specifically provided.

[0050] Furthermore, the length of the connecting plate 3 ranges from 25 to 110 mm; the width ranges from 8 to 12 mm; and the height ranges from 2 to 6 mm. Specifically, the first connecting plate has a length of 50.3 mm, a width of 10 mm, and a height of 4 mm; the second connecting plate has a length of 103.5 mm, a width of 10 mm, and a height of 4 mm; and the third connecting plate has a length of 46.1 mm, a width of 10 mm, and a height of 4 mm. The specific dimensions of the connecting plates are not limited here and are set according to actual production needs.

[0051] In this embodiment, the base 1 is also provided with a fourth through hole 12, and a third connector 7 is connected through the fourth through hole 12 to connect the base 1 to the vibration test bench.

[0052] Specifically, the base 1 is fixed to the vibration test bench by setting multiple mounting holes and passing through the mounting holes with 8 M8×20 bolts. This makes the installation of the vibration test fixture on the vibration test bench simple and reliable, ensuring the effect of vibration test. It can well simulate the product's installed state, meet the product's vibration test requirements, and solve the problems of insufficient stability and limited number of products that existing impact vibration fixtures can support during clamping.

[0053] Furthermore, the specific steps of the power module 4 impact vibration test fixture in this embodiment are as follows:

[0054] Place the vibration fixture in the corresponding position on the vibration test bench, align the third through hole 31 of the vibration fixture with the mounting hole of the vibration test bench, and tighten with M8×20 bolts. The installation process of the vibration fixture is simple, reliable, convenient, and quick, and provides good tightening effect after installation. After the vibration fixture is installed on the test bench, place the power module 4 in the product slot 11 on the base 1, align the first through holes 21 at both ends of the positioning component 2 with the threaded holes on the base plate, and tighten with M3×16 bolts. Finally, align the third through hole 31 of the connecting plate 3 with the second through hole 22 on the positioning component 2, and tighten with M3×8 bolts to begin the vibration test. The M8×20, M3×16, and M3×8 bolts are all made of SUS304 stainless steel.

[0055] In summary, the power module 4 impact vibration test fixture in this embodiment has reliable connections between its various parts and good mechanical properties; the vibration fixture is simple and reliable to install on the vibration test bench, ensuring the vibration test effect and simulating the product's installation state well, thus meeting the product's vibration test requirements; at the same time, this utility model can simultaneously place 36 individual power modules 4 for testing, reducing vibration time and improving the efficiency of vibration testing.
