[0035] Please see Figure 1 . Figure 1 This is a partial three-dimensional structural diagram of the cabinet in one embodiment.
[0036] In this embodiment, the cabinet 1 includes a cabinet body 10, a plurality of electronic devices 20, and at least one shock-absorbing mechanism 30. These electronic devices 20 are, for example, servers, and are mounted within the cabinet body 10 via slide rails (not shown). The shock-absorbing mechanism 30 is disposed within the cabinet body 10, and will be described in detail below.
[0037] Please see Figures 2 to 4 . Figure 2 for Figure 1 A three-dimensional structural diagram of the shock absorption mechanism in its first state. Figure 3 for Figure 1 A three-dimensional structural diagram of the shock absorption mechanism in the second state. Figure 4 for Figure 1 A three-dimensional structural diagram of the shock absorption mechanism in the third state. In this embodiment, the shock absorption mechanism 30 may be selectively in the first state, the second state, or the third state.
[0038] First, let's explain the shock absorption mechanism 30 in its first state. For example... Figure 2As shown, the shock absorption mechanism 30 includes a housing 31 and a counterweight assembly 32. The counterweight assembly 32 includes a counterweight plate 321. The housing 31 is similar to, for example, a server housing, so that the housing 31 can also be mounted inside the cabinet 10 via slide rails. The housing 31 includes a base plate 311 and two side plates 312, which are respectively connected to opposite sides of the base plate 311. The base plate 311 of the housing 31 includes a bearing surface 3111. The counterweight plate 321 is, for example, but not limited to, a flat plate. The counterweight plate 321 is disposed inside the housing 31 and is located on the bearing surface 3111 of the housing 31.
[0039] Next, the damping mechanism 30 in its second state will be described. For example... Figure 3 As shown, the counterweight assembly 32 may include a counterweight block 322 in addition to the counterweight plate 321. This counterweight block 322 is disposed on the surface of the counterweight plate 321 opposite to the bearing surface 3111, for example, but not limited to, by means of screws or adhesive. The centerline C of the base plate 311 of the housing 31 is parallel to the normal N of the bearing surface 3111 and passes through the counterweight block 322.
[0040] Next, the damping mechanism 30 in its third state will be described. For example... Figure 4 As shown, the counterweight assembly 32 has multiple counterweight blocks 322, and these multiple counterweight blocks 322 are arranged one-to-one at the corners of a polygon P, and the center line C of the housing 31 passes through the centroid G of the polygon P. For example, the shock absorption mechanism 30 has four counterweight blocks 322, and these counterweight blocks 322 are arranged one-to-one at the four corners of a quadrilateral (such as a rectangle), and the center line C of the housing 31 passes through the centroid G of the quadrilateral.
[0041] The thickness of the plates of the outer casing 31 (such as the base plate 311 and the side plate 312) can be in the range of 1 mm to 1.5 mm, and the thickness of the counterweight plate 321 can be in the range of 1 mm to 1.5 mm. Further, the thickness of the plates of the outer casing 31 can be in the range of 1 mm to 1.2 mm, and the thickness of the counterweight plate 321 can be in the range of 1 mm to 1.2 mm. On the other hand, the weight of the counterweight 322 is, for example, 1.5 kg.
[0042] As shown in Table 1, after finite element simulation, the damping mechanism 30 under different states and parameters can provide significant damping effect for vibrations in a specific frequency range.
[0043]
[0044] Next, the following explains how to determine which type of vibration damping mechanism 30 to use. First, the resonant frequency range of the cabinet 10 and the electronic devices 20 within it is experimentally measured to determine the desired vibration frequency range for damping. Assuming the desired vibration frequency range is 15-20Hz, the third-state vibration damping mechanism 30 can be used and placed inside the cabinet 10. Random vibration simulations are then performed to verify whether the vibration damping mechanism 30 achieves its damping effect. For example, please refer to... Figure 5 And Table 2. Figure 5 for Figure 1 Table 2 shows the acceleration and frequency curves of cabinet 1 with different numbers of vibration damping mechanisms. Table 2 summarizes the vibration simulation results using different numbers of vibration damping mechanisms.
[0045]
[0046] from Figure 5 As shown in Table 2, the vibration damping mechanism 30 helps reduce vibration, and the more vibration damping mechanisms 30 there are, the better the vibration damping effect. In other words, the number of vibration damping mechanisms 30 is positively correlated with the vibration damping effect. With 12 vibration damping mechanisms 30 configured in the cabinet 1, vibration can be reduced by about 50%.
[0047] Therefore, by setting the shock absorption mechanism 30 inside the cabinet 10, and the shock absorption mechanism 30 including the outer shell 31 and the counterweight component 32, and the counterweight component 32 being set inside the outer shell 31, the vibration transmitted to the electronic device 20 inside the cabinet 1 can be reduced during the transportation of the cabinet 1, so as to ensure that the electronic device 20 inside the cabinet 1 can operate normally after the cabinet 1 is delivered to the designated location.
[0048] In the second state of the shock-absorbing mechanism 30, the center line C of the bottom plate 311 of the outer shell 31 passes through the counterweight 322. In the third state of the shock-absorbing mechanism 30, the counterweight 322 is located at the corner of the polygon P and the center line C of the outer shell 31 passes through the center of gravity G of the polygon P. This configuration can further improve the shock absorption effect of the shock-absorbing mechanism 30.
[0049] It should be noted that the position of the counterweight 322 of the shock absorption mechanism 30 in the second and third states on the counterweight plate 321 is not intended to limit the present invention, but can be adjusted arbitrarily according to requirements.
[0050] Furthermore, the shock absorption mechanism 30 is not limited to only the first, second, and third states described above. In other embodiments, the number of counterweight plates and counterweight blocks of the shock absorption mechanism, as well as the position of the counterweight blocks on the counterweight plates, can be adjusted as needed, allowing the shock absorption mechanism to have more different states to achieve the desired shock absorption effect.
[0051] In this embodiment, the server of this application can be used for artificial intelligence (AI) computing, edge computing, and can also be used as a 5G server, cloud server or vehicle networking server.
[0052] The aforementioned cabinet and shock absorption mechanism, with the shock absorption mechanism installed inside the cabinet, and the shock absorption mechanism including an outer shell and a counterweight component, with the counterweight component installed inside the outer shell, can reduce the vibration transmitted to the electronic devices inside the cabinet during the transportation of the cabinet, so as to ensure that the electronic devices inside the cabinet can operate normally after the cabinet is delivered to the designated location.
[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
