[0002] Existing power supply devices use cooling fans for heat dissipation. Generally, the cooling fan is fixed to the fan bracket by screws, and then the fan bracket is fixed to the housing of the power supply device. However, when the cooling fan rotates, it will generate vibrations of a certain frequency. This vibration will resonate with other electronic components through the fan bracket, especially affecting the data storage of the hard disk and causing data loss. The fan bracket and screws will increase the assembly cost.

[0003] Therefore, it is necessary to provide a fixing structure and an electronic device equipped with the fixing structure which can effectively reduce resonance and lower assembly cost, so as to solve the above problems. Utility Model Content

[0031] See also Figures 1 to 4 , Figure 1 This is an internal view of an electronic device 1 according to an embodiment of the present invention. Figure 2 for Figure 1A partial stereoscopic view of the housing 10 in FIG. Figure 3 for Figure 1 A three-dimensional diagram of the cooling fan 12, Figure 4 for Figure 1 A three-dimensional view of the fixing member 142 in FIG.

[0032] like Figures 1 to 4 As shown in FIG. 1 , in one embodiment of the present invention, the electronic device 1 comprises a housing 10, a cooling fan 12 and a fixing structure 14. The electronic device 1 may be a power supply device or other device equipped with a cooling fan 12, depending on the actual application. The housing 10 comprises a bottom plate 100, such as Figure 1 and Figure 2 The cooling fan 12 is disposed in the housing 10, and the cooling fan 12 includes a fixing hole 120, as shown in FIG. Figure 1 and Figure 3 In this embodiment, the four corners of the heat dissipation fan 12 may include four fixing holes 120 .

[0033] like Figure 1 As shown, the fixing structure 14 includes a bending portion 140 and a fixing member 142. Figure 2 As shown, the bending portion 140 is bent from the bottom plate 100 of the housing 10, and the bending portion 140 includes a slot 1400. In this embodiment, corresponding to the four fixing holes 120 at the four corners of the heat dissipation fan 12, the fixing structure 14 may include four bending portions 140 and four fixing members 142. When assembling the heat dissipation fan 12 to the housing 10, the fixing member 142 may be inserted into the fixing hole 120 of the heat dissipation fan 12 and engaged with the slot 1400 of the bending portion 140, so as to fix the heat dissipation fan 12 on the bottom plate 100 of the housing 10.

[0034] like Figure 4 As shown, the fixing member 142 includes a head 1420, a locking portion 1422, a shoulder 1424, a holding portion 1426 and an inserting portion 1428, wherein the locking portion 1422 connects the head 1420 and the shoulder 1424, and the holding portion 1426 connects the shoulder 1424 and the inserting portion 1428. In this embodiment, the fixing member 142 is flexible and can be made of a flexible material, such as rubber or plastic, depending on the actual application.

[0035] Combination Figure 1 , Figure 4As shown, when assembling the heat dissipation fan 12 to the housing 10, the insertion portion 1428 of the fixing member 142 can be inserted into the fixing hole 120 of the heat dissipation fan 12, so that the holding portion 1426 of the fixing member 142 is engaged with the fixing hole 120 of the heat dissipation fan 12. In this embodiment, the holding portion 1426 can have a plurality of protruding structures 1430, wherein the plurality of protruding structures 1430 are arranged at intervals along the axial direction of the fixing member 142. Since the fixing member 142 is made of a flexible material, the protruding structure 1430 is flexible. When the insertion portion 1428 and the holding portion 1426 of the fixing member 142 are sequentially inserted into the fixing hole 120 of the heat dissipation fan 12, the protruding structure 1430 is squeezed by the fixing hole 120 and elastically deformed, so that the holding portion 1426 is tightly engaged with the fixing hole 120. In this way, the engagement between the fixing member 142 and the heat dissipation fan 12 can be made more stable.

[0036] Next, the engaging portion 1422 between the head 1420 and the shoulder 1424 can be engaged in the engaging groove 1400 of the bending portion 140, so that the bending portion 140 is clamped between the head 1420 and the shoulder 1424. In this embodiment, the diameters of the head 1420 and the shoulder 1424 are greater than the width of the engaging groove 1400, so that the bending portion 140 is firmly clamped between the head 1420 and the shoulder 1424.

[0037] See also Figure 1 As shown, in this embodiment, the electronic device 1 may further include at least one buffer 16, and the buffer 16 is disposed on at least one side of the heat dissipation fan 12. Figure 1 As shown, the buffer 16 can be disposed on the upper side of the cooling fan 12. It should be noted that another buffer 16 can also be disposed on the lower side of the cooling fan 12. After the electronic device 1 is assembled, the buffer 16 can contact the housing 10 to isolate the vibration of the cooling fan 12. The buffer 16 can be made of rubber, elastic foam or other similar materials, depending on the actual application.

[0038] In summary, the cooling fan 12 of the present invention is connected to the housing 10 through the bent portion 140 of the fixing structure 14 and the fixing member 142, thereby isolating the vibration of the cooling fan 12 and effectively reducing the resonance of the housing 10 and other electronic components. In addition, the present invention uses the bent portion 140 bent from the bottom plate 100 of the housing 10 to replace the fan bracket, which can save the fan bracket and screws and effectively reduce the assembly cost. Furthermore, the present invention can set at least one buffer member 16 on at least one side of the cooling fan 12 to isolate the vibration of the cooling fan 12 and further reduce the resonance of the housing 10 and other electronic components.

[0039] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model.
