1 is a perspective view of a preferred embodiment of a power supply assembly of the present invention.

Figure 2 is an exploded view of Figure 1 with the body in partial cross-section.

Referring to Figures 1 and 2, a preferred embodiment of the power supply assembly of the present invention is used to power a computer host. The power supply combination includes a body 10, two fans 50, and two sets of fan frames 30.

The body 10 defines a receiving cavity 12 for mounting the fan 50. The accommodating cavity 12 includes a pair of oppositely disposed mounting walls 14, two venting walls 161, 162 vertically connected between the two mounting walls 14, and a bottom wall (not labeled). A plurality of ventilation holes 160 are defined in the ventilation wall 161 to facilitate ventilation and heat dissipation of the power supply. The ventilation wall 162 is provided with a vent corresponding to the fan 50. Two rows of protrusions are disposed on the inner side of each of the mounting walls 14 in the longitudinal direction, and include two protrusions 142 forming a row adjacent to the ventilation wall 161 and two protrusions 144 forming a row away from the ventilation wall 161. Each of the mounting walls 14 defines a slot 148 between the two protrusions 142, 144 located above and between the protrusion 142 located above and the ventilation wall 161. Two protrusions 146 are also disposed in the lateral direction of each of the mounting walls 14. The height of the two protrusions 146 is lower than below The horizontal surfaces of the two protrusions 142, 144 are located, and the two protrusions 146 are located directly below the two card slots 148.

The fan 50 is a conventional fan, and is provided with mounting holes 52 at four corners thereof.

Each set of fan trays 30 includes two brackets 40. Hereinafter, only one bracket 40 will be described as an example. The bracket 40 includes a horizontally-shaped first body 41 and a rectangular second body 42 extending vertically from one side of the first body 41. An elastic member 43 extends from the top end of the second body 42. The elastic member 43 is an L-shaped elastic piece which is extended vertically upwards and then horizontally. A wedge-shaped buckle 432 is formed on the outer side of the vertical portion of the elastic member 43. A horizontal portion of the elastic member 43 defines a through hole 434. The bracket 40 further includes two positioning pieces 44 and two other positioning pieces 45. The positioning piece 44 and the positioning piece 45 are both triangular. The two positioning pieces 44 are perpendicularly connected to the first piece body 41 and the second piece body 42 respectively, and are oppositely disposed on opposite sides of the first piece body 41 and the second piece body 42. The two positioning pieces 45 are formed by the second piece body. 42 extend vertically and are disposed on opposite sides of the elastic member 43 at a relatively interval.

During assembly, for each fan 50, the two brackets 40 of the set of fan frames 30 are relatively sleeved on the left and right sides of the fan 50. The four corners of the fan 50 are respectively caught between the corresponding two positioning pieces 44 and between the two positioning pieces 45. The second body 42 of the two brackets 40 are respectively attached to the left and right sides of the fan 50. The first body 41 of the two brackets 40 are attached to the bottom surface of the fan 50, and the horizontal portion of the elastic member 43 of the two brackets 40. It is attached to the top surface of the fan 50. Then, the fan 50 and the fan frame 30 mounted thereon are pushed into the accommodating cavity 12 of the body 10. The bracket 40 of the fan frame 30 is slid into the accommodating cavity 12 between the protrusion 142 and the protrusion 144, and the other fan frame 30 is slid into the accommodating cavity 12 between the protrusion 142 and the ventilating wall 161. In the process, each support The buckle 432 of the seat 40 is pressed by the corresponding mounting wall 14 such that the resilient member 43 produces an inward elastic deformation. When the buckle 432 is fully inserted into the slot 148, the elastic member 43 is elastically restored, and the flat end of the buckle 432 is locked at the top edge of the slot 148. At this time, the first piece 41 of the bracket 40 abuts against the corresponding Protrusion 146.

During the disassembly, for each fan 50, the operator can extend the two fingers into the through holes 434 of the two brackets 40 of the fan frame 30, and relatively pull the two elastic members 43 so that the buckle 432 on the elastic member 43 is The corresponding card slot 148 is disengaged and then, together with the fan 50, the fan tray 30 can be pulled out.

The power supply combination of the present invention adopts a split design, and the fan 50 can be easily disassembled to facilitate maintenance and replacement of the fan 50. In addition, in the present embodiment, two fan 50 designs are adopted, so that designers and users have more choices, that is, two fans 50 can be used simultaneously or separately to meet different noise levels and heat dissipation requirements. It is also possible to use two fans 50 to obtain a redundancy function, that is, in the working state, one fan 50 can be used as a backup fan of another fan 50 in a sudden situation (such as damage).

In addition, a bump 442 may be disposed inside the positioning pieces 44, 45 of each bracket 40. Thus, when the bracket 40 is mounted on the fan 50, the bumps 442 can be further used to snap into the mounting holes 52 of the fan 50 to position the fan.

It is easily conceivable that in other embodiments, the protrusions 146 can be omitted and the first body 41 of the bracket 40 can be directly abutted against the bottom wall of the accommodating chamber 12. In addition, the receiving cavity 12 of the body 10 can also be designed to accommodate only one fan or to accommodate three or more fans side by side. When the accommodating cavity 12 is designed to accommodate only one wind When the fan is used, the protrusions 142 and the protrusions 144 which act to separate the fan and guide the fan to slide into the accommodating cavity 12 can be omitted; when the accommodating cavity 12 is designed to accommodate three fans side by side, a column and a protrusion 142 need to be added. 144 parallel protrusions.

In other embodiments, each fan 50 can also be assembled to a bracket 40 and then slidably mounted on the body 10 .

In other embodiments, the elastic member 43 can be provided with a card slot, and the mounting wall 14 of the body 10 is correspondingly provided with a wedge-shaped block that can be snapped to the card slot.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art will be included in the following claims.
