Combination of fan and fan fixing mechanism

A fixed structure, particularly related to a fan fixing mechanism.

With the rapid advancement of high-speed computers, various electronic components (such as central processing units (CPUs), integrated circuits (ICs)) in computers consume more and more heat. Therefore, cooling fans have been widely used, but with With the increasing popularity of information and the amount of information being processed, there is no doubt that the speed of future processors will increase. In contrast, heat dissipation to the processor is a problem that computer-related developers must face in the future.

Since electronic components in a computer operate at a high temperature, it is prone to instability. In order for the electronic components to operate stably and normally, it is necessary to efficiently and quickly dissipate the heat generated by the electronic components. Generally, the most direct way to dissipate heat is to install a heat sink or a fan on the electronic component, so that the heat generated by the electronic component can be quickly transferred to the heat sink, or the heat can be removed by the fan in a forced convection manner to achieve heat dissipation. purpose.

The features and implementations of the present invention are described in detail below with reference to the drawings.

Please refer to FIG. 2A, which is a combination diagram of a fan structure of the present invention. The fan fixing mechanism 210 includes a carrier plate 230 and a latching component 212. The carrier plate 230 further has a loading and unloading hole 231, at least one positioning hole 232, a fan bearing surface 233, and an outer side surface 234 opposite to the fan bearing surface 233.

Each of the positioning holes 232 includes at least a sleeve area 2321, a positioning area 2323, and a connection area 2322 that connects the sleeve area 2321 to the positioning area 2323. Each of the connection regions 2322 extends from the nesting area 2321 in a first direction 510 to the positioning area 2323.

The card abutment assembly 212 has two ends opposite to each other, that is, a card abutting end 2302 and a connecting end 2301 connected to the carrier plate 230. The connecting end 2301 can be connected to the carrier plate 230 through various components, such as a card structure, a screw or a rivet, or can be integrally formed from the carrier plate 230. The snap-fit assembly 212 extends toward the first direction 510. The snap-in assembly 212 passes through the loading and unloading hole 231 (please refer to the "Fig. 2B"). The area of the loading and unloading hole 231 is approximately larger than the latching component 212, so that the latching end 2302 of the latching component 212 can pass from the outer side 234 of the carrying plate 230 through the loading and unloading hole 231 to the fan carrying surface 233. Therefore, the shape of the card abutting component 212 can be a bevel or a curved surface, and the bevel (or curved surface) passes through the fan bearing surface 233 after the connecting end 2301 passes through the outer side 234.

The fan further includes a fan body 220 and a fan cover 240. The fan body 220 has a gas flow port 250 coupled to the fan body 220 and located on the gas flow port 250, and the fan cover 240 is interposed between the fan body 220 and the fan bearing surface 233. The fan bearing surface 233 is a junction between the carrier plate 230 and the fan body 220.

A fixing assembly 221 having the same number as the at least one positioning hole 232 is disposed in a side surface of the fan body 220 facing the fan bearing surface 233. One end of the fixing component 221 is connected to the fan body 220, and the other end is inserted into the positioning hole 232. In addition, the one end of the fixing component 221 that is inserted into the positioning hole 232 can be covered with the shock absorbing pad 260. The shock absorbing pad 260 is disposed between the fixing component 221 and the positioning hole 232, thereby reducing the vibration of the fan body 220. Bad effects on the fan fixing structure 210.

The appearance of the fixing assembly 221 is further described herein. The fixing assembly 221 is formed by connecting the first block 261, the second block 262 and the third block 263 in series. The cross-sectional area of the first block 261 is larger than the cross-sectional area of the second block 262, and the cross-sectional area of the third block 263 is larger than the cross-sectional area of the second block 262. The cross-sectional area of the first block 261 is smaller than the nesting area 2321, and the cross-sectional area of the first block 261 is larger than the connecting area 2322 and the positioning area 2323.

In the "Fig. 2B", four fixing members 221 are taken as an example. Therefore, a plurality of positioning holes 232 are also provided on the fan carrying plate 230. The cross-sectional area of the splicing area 2321 is larger than the cross-sectional area of the locating area 2323 and the cross-sectional area of the first block 261 of the fixing component 221, and the cross-sectional area of the positioning area 2323 is smaller than that of the first block 261 of the fixing component 221. Cross-sectional area.

Hereinafter, the installation of the fan body 220 will be described. Please refer to "2C" and "2D", which are cross-sectional views of the fan according to the present invention before and after the fixing structure is placed. Firstly, the fixing assembly 221 of the fan body 220 is individually embedded in the tying area 2321 of the positioning hole 232 at the corresponding position on the carrier plate 230. Since the cross-sectional area of the nesting area 2321 is larger than the cross-sectional area of the first block 261 of the fixing assembly 221, and each of the connecting areas 2322 extends from the nesting area 2321 in the same first direction 510 to the positioning area 2323, The joint assembly 221 can slide toward the positioning area 2323. In other words, the fan body 220 can be slid from the nesting area 2321 to the positioning area 2323.

Then, since the cross-sectional area of the first block 261 of the fixing component 221 is larger than the cross-sectional area of the connecting area 2322 and the positioning area 2323, the fan body 220 slides over the fan carrying surface 233, and the fan body 220 will abut the component. 212 is pushed out toward the outer side surface 234 of the carrier plate 230 as shown in "Fig. 2C". After the fan body 220 is slid to the position, the card abutting end 2302 of the latching component 212 (the end originally passing through the loading and unloading hole 231) does not interfere with the fan body 220, so the card abutting end 2302 will face from the outer side 234. The fan bearing surface 233 rebounds, as shown in FIG. 2D, such that the card abutment assembly 212 abuts against the side of the fan body 220. Therefore, the fan body 220 will not slip back from the positioning area 2323 to the nesting area 2321.

Please refer to "3A" and "3B", which are another fan structure combination diagram according to the present invention. The carrier plate 230 has a loading and unloading hole 231 and at least one positioning hole 232 and a fan bearing surface 233. The fan further includes a fan body 220 and a fan cover 240. The fan body 220 has a gas flow port 250 coupled to the fan body 220 and located on the gas flow port 250, and the fan cover 240 is interposed between the fan body 220 and the fan bearing surface 233. As shown in the previous embodiment, the fixing member 221 of the same number as the positioning hole 232 is disposed in the side of the fan body 220 facing the fan bearing surface 233. One end of the fixing component 221 is connected to the fan body 220, and the other end is inserted into the positioning hole 232. Moreover, the end of the fixing component 221 inserted in the positioning hole 232 can cover the surface of the suspension pad 260 to increase the connection stability between the fan body 220 and the fan fixing structure 210.

In addition, a protrusion 241 is further disposed at a position of the corresponding abutting component 212 of the fan cover 240 , and the latching component 212 abuts against the side of the fan body 220 via the protrusion 241 . In this embodiment, the connection end 2301 of the card abutment assembly 212 is still connected to the carrier plate 230, and the card abutment end 2302 is bent from the fan bearing surface 233 toward the fan body 220 (eg, FIG. 3A). Shown). In this embodiment, the direction in which the bumps 241 extend is the same as the direction in which the latching members 212 are bent. The outer side surfaces 234 of the carrier plates 230 extend in the direction of the fan bearing surface 233.

The fixing assembly 221 of the fan body 220 is individually embedded in the tying area 2321 of the positioning hole 232 at the corresponding position on the carrier plate 230. The first block 261, the second block 262 and the third block 263 are respectively connected in series to form a positioning structure. The cross-sectional area of the first block 261 is larger than the cross-sectional area of the second block 262, and the cross-sectional area of the third block 263 is larger than the cross-sectional area of the second block 262. The cross-sectional area of the first block 261 is smaller than the nesting area 2321, and the cross-sectional area of the first block 261 is larger than the connecting area 2322 and the positioning area 2323. Therefore, the action of sliding the fan body 220 from the nesting area 2321 toward the positioning area 2323 is performed. As described above, the fixing assembly 221 is fixed in the positioning area 2323 so that the fan body 220 is also fixed, and the fixing assembly 221 can also provide a buffering function between the fan body 220 and the carrier plate 230. When the fan body 220 is fixed, the protrusion 241 will abut the front edge of the card abutment assembly 212, and the fixed fan body 220 will not be displaced back. Therefore, the fan body 220 will not slide from the positioning area 2323 to the sleeve area 2321 ( As shown in "Figure 3B"). In this way, the degree of fixing of the fan body 220 on the carrier plate 230 can be increased. For example, "3C" and "3D".

In addition to the above-described embodiments, the present invention further provides a variation of the card abutment component 212 with an increase in the area of the card against the side of the fan body 220. Please refer to FIG. 4A to FIG. 4D, which are schematic diagrams of the third embodiment of the present invention and its operation diagram.

In the "Fig. 4A", a bent portion 2121 is additionally provided at the card end 2302 of the card abutting member 212. The curved portion 2121 is bent from the fan bearing surface 233 toward the outer side surface 234 of the inclined surface 2303 of the carrying plate 230, and the side of the fan body 220 is cut flat, so that the card abutting end 2302 of the latching component 212 can have a larger area. It can be against the fan body 220. As described above, while the fan body 220 slides over the carrier plate 230, the fan body 220 pushes the card abutment assembly 212 toward the outer side surface 234 of the carrier plate 230, "FIG. 4C." After the fan body 220 is slid to the position, the card abutting end 2302 of the latching component 212 (the card abutting end 2302 originally passing through the loading and unloading hole 231) does not interfere with the fan body 220, so the card abutting end 2302 will be from the outer side. The 234 rebounds in the direction of the fan bearing surface 233 such that the side of the latching component 212 corresponding to the fan body 220 will abut. Therefore, the fan body 220 will not slide back from the positioning area 2323 to the nesting area 2321, "4D".

Further, a cushion 2122 may be additionally provided on the contact surface of the curved portion 2121 and the fan body 220. When the fan body 220 is slid to the positioning, the bending portion 2121 is abutted against the side of the fan body 220 via the cushion 2122. Please refer to FIG. 5 to make the fan body 220 operate. When the fan body 220 is guided to the fixed position, the card abutting component 212 abuts against one side of the fan body 220, thereby fixing the fan body 220 to the carrier plate 230. Therefore, the fan fixing mechanism 210 of the present invention can fix the fan body in the fan fixing mechanism 210 without an additional positioning member (or screw) as compared with the prior art. In addition to improving the assembly efficiency of the fan, the assembly cost of the fan can also be reduced.

While the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. The patent protection scope of the invention is subject to the definition of the scope of the patent application attached to the specification.
