[0017] like Figure 1As shown, in this embodiment, the utility model includes an electric control box 1, a test module 2 and a fixed flat plate 3. The fixed flat plate 3 is arranged on the upper surface of the electric control box 1. The electric control box 1 is provided with observation windows 10 on both sides. The test module 2 is fixed on the fixed flat plate 3. The test module 2 is provided with a product to be tested 4. The test module 2 is provided with a communication line 5. The test module 2 is connected to an external device via the communication line 5. It can be seen that the test module 2 and the fixed flat plate 3 are both fixed on the electric control box 1. The test module 2 is used to place and fix the product to be tested 4 and collect product vibration data. The communication line 5 is connected to an external device to control the vibration of the product to be tested 4 and transmit the product vibration data to the external device.

[0018] like Figure 1 As shown, in this embodiment, both sides of the electric control box 1 are provided with observation windows 10. It can be seen that the observation windows 10 serve to observe the working status of the control components inside the electric control box 1.

[0019] like Figure 1 As shown, in this embodiment, the bottom of the electrical control box 1 is provided with a plurality of adjustable shock-absorbing pads 11, which are in contact with the ground. Thus, before testing, the adjustable shock-absorbing pads 11 can be used to adjust the level of the test module 2, so that the product under test 4 can vibrate in a horizontal state, reducing the impact of gravity on the product under test 4. At the same time, it can also isolate external environmental vibrations, preventing external environmental vibrations from affecting the test results, which is conducive to improving the accuracy of the test data.

[0020] like Figure 2 As shown, in this embodiment, the test module 2 includes a test base plate 20, a test carrier assembly 21, a support assembly 22, and a plurality of limit blocks 23. The test base plate 20 is fixed on the fixed flat plate 3, the support assembly 22 and the limit blocks 23 are both fixed on the test base plate 20, the test carrier assembly 21 floats with the support assembly 22, the test carrier assembly 21 is limitedly matched with the product to be tested 4, and a plurality of limit blocks 23 are evenly distributed around the test carrier assembly 21, and the limit blocks 23 are limitedly matched with the product to be tested 4. It can be seen that the fixed plate 3 supports the test base plate 20, the test carrier assembly 21 and the support assembly 22 float together, and the support assembly 22 also supports the test carrier assembly 21 and the product to be tested 4, allowing them to vibrate freely. The several limit blocks 23 limit the product to be tested 4, and the test carrier assembly 21 fixes the product to be tested 4 and the several acceleration sensors 211.

[0021] like Figures 3 and 4 As shown, in this embodiment, the test carrier assembly 21 includes a carrier element 210 and a plurality of acceleration sensors 211. The carrier element 210 is provided with a plurality of fixing blocks 212. The carrier element 210 is limitedly matched with the fixing blocks 212 and the product to be tested (4). The fixing blocks 212 are limitedly matched with the acceleration sensors 211. It can be seen that the carrier element 210 plays a role in fixing the plurality of fixing blocks 212 and the product to be tested 4, and the fixing blocks 212 play a role in fixing the acceleration sensors 211. The acceleration sensors 211 collect vibration data of the product to be tested 4 and play a role in detection.

[0022] like Figure 3 As shown, in this embodiment, a level 24 is provided on the test base plate 20, and the level 24 is fixed to the test base plate 20. As can be seen, the level 24 is used to monitor the levelness of the test module 2, ensuring the levelness of the test module 2 before testing, so that the product 4 to be tested can vibrate in a horizontal state, which is conducive to improving the accuracy of the test data.

[0023] like Figure 3 As shown, in this embodiment, a second shock-absorbing pad 25 is provided between the test base plate 20 and the fixed plate 3. Thus, the second shock-absorbing pad 25 is provided to reduce external environmental vibration, thereby preventing the external environmental vibration from affecting the test results, thereby improving the accuracy of the test data.

[0024] like Figure 4 As shown, in this embodiment, the fixing block 212 is provided with a threaded base 213 and a knob 214. The fixing block 212 is limited and matched with the threaded base 213 through a magnet 215. The threaded base 213 is threadedly matched with the knob 214. The threaded base 213 is limited and matched with the carrier element 210 through a screw. It can be seen that the threaded base 213 and the knob 214 are provided on the fixing block 212, so that the acceleration sensor 211 can be tightly fitted with the product to be tested 4. The threaded base 213 and the knob 214 are threadedly matched to adjust the fitting position of the acceleration sensor 211. At the same time, the fixing block 212 is limited and matched with the threaded base 213 through the magnet 215. The magnet 215 plays a role in limiting and positioning the fixing block 212 and the threaded base 213, and also facilitates the disassembly and replacement of the threaded base 213. Compared with traditional glue and screws, the installation efficiency and component reuse rate are improved.

[0025] like Figure 4As shown, in this embodiment, the carrier element 210 is provided with a plurality of positioning pins 216, and the positioning pins 216 are engaged with the fixing block 212. Thus, the positioning pins 216 play a role in positioning and limiting the fixing block 212 when engaging with the fixing block 212.

[0026] In this embodiment, the working principle of the utility model is as follows:

[0027] like Figures 1 to 4 As shown, the operator places the product to be tested 4 into the carrier element 210, then fixes several of the acceleration sensors 211 on the fixing block 212, rotates the knob 214, and tightens the knob 214 and the threaded base 213 so that the acceleration sensors 211 are fitted and fixed to the product to be tested 4, repeats the tightening steps in sequence, and fits and fixes the remaining acceleration sensors 211 to the product to be tested 4. When all the acceleration sensors 211 are fitted and fixed to the product to be tested 4, observe the spirit level 24. If the levelness of the test module 2 is not enough, adjust the second shock-absorbing foot pad 25 or the adjustable shock-absorbing foot pad 11. When the levelness of the test module 2 meets the test conditions, the vibration test of the product to be tested 4 can be started. When the test is accepted, rotate the knob 214 in the opposite direction to release the acceleration sensor 211 from the tested product, and the fixing block 212 is reset under the action of the magnet 215, and the cycle is repeated.

[0028] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
