明如下。 【實施方式】 请參考「第2A圖」所示，其係為本發明之一種風扇結構組合 圖。風扇固定機構210包括承載板230與卡抵組件212。承載板 230另具有裝卸孔231、至少一定位孔232、風扇承載面233以及 與風扇承載面233相對的外側面234。 而每一個定位孔232至少包含套合區2321、定位區2323以及 將套合區2321連通於定位區2323的連接區2322。而每一個連接 區2322是由套合區2321沿一第一方向510而延伸至定位區2323。 卡抵組件212具有彼此相對的兩端，即卡抵端23〇2以及連接 於承載板230的連接端2301。連接端2301可以透過各種的元件連 接於承載板230 ’例如：卡制結構、螺絲或鉚釘，也可以是從承載 板230處一體成型的延伸出來。卡抵組件212係朝向與第一方向 510延伸。而卡抵組件212穿過裝卸孔231 (請配合「第2B圖」 201245583 所示）。裝卸孔231的面積約略大於卡抵組件212，使得卡抵組件 212的卡抵端2302可以從承載板230的外側面234穿過裝卸孔231 至風扇承载面233。因此，卡抵組件212的造型可以是一斜面或曲 面，其斜面（或曲面）係由連接端2301經過外側面234後在穿過 風扇承載面233 = 而風扇更包括風扇本體220以及風扇罩240。風扇本體220 具有氣體流通口 250 ’風扇罩240結合於風扇本體220並且位於氣 體流通口 250上，並且風扇罩240介於風扇本體220與風扇承載 面233之間。風扇承載面233係為承載板230與風扇本體220間 的接面。 在風扇本體220面對於風扇承載面233的側面中設置與至少 一定位孔232數量相同的固接組件221。在固接組件221的一端連 接於風扇本體220，而另一端插設於定位孔232内。此外，固接組 件221之插設於定位孔232内的一端更可以包覆避震墊26〇，其中 避震墊260設置於固接組件221與定位孔232之間.，藉以降低風 扇本體220震動時對於風扇固定結構21〇的不良影響。 在此進一步說明固接組件221的外觀.，固接組件221分別由 第一區塊261、第二區塊262與第三區塊263所串接而成。第一區 塊261的截面積大於第二區塊262的截面積，且第三區塊2纪的 截面積大於第二區塊262的截面積。第一區塊261的截面積小於 套合區2321’且第一區塊261的截面積大於連接區2322與定位區 2323。 201245583 、在「第2B圖」+係以四個固接組件221為例，因此在風扇承 載板230上也設置數量為四個的定位孔於其中，且套合區灿 的截面積大於定位區2323的截面積與固接組件221的第一區塊 261的截面積，定位區2323的截面積小於固接組件221的第一區 塊261的截面積。 以下係對風扇本體22G的裝設進行說明，請參照「第2(：圖」 ”第2D目」’#係分別為依據本發明之風扇置入固定結構前與 置入後之剖面圖。首先將風扇本體22()的固接組件221個別的嵌 入承載板230上對應位置的定位孔攻之套合區2321中。由於套 合，2321的截面積大於固接組件221的第—區塊261的截面積， 且每-個連接區2322是由套合區2321沿同—第一方向51〇而延 伸至定位區2323’所以固接組件221可以朝向定位區2323進行滑 移的動作’換句話說，可以將風扇本體22〇由套合區2321往定位 區2323滑移。 之後由於固接組件221的第一區塊261的截面積大於連接區 2322以及定倾2323職面積，因此風扇本體22()在風扇承載面 33上π過的同時’風扇本體22〇會將卡抵組件ha往承載板23〇 的外側面234麼出’如「第2C圖」所示。當風扇本體在滑移 到定位後’卡抵組件212的卡抵端通（前述原本穿過裝卸孔231 的那端）由於沒有風扇本體22〇干涉，所以卡抵端2搬會從外 侧面234朝向風扇承載面233回彈，如「第犯圖」所示，使得卡 抵組件212與風扇本體22〇的側邊相抵住。所以風扇本體，將 201245583 不會由定位區2323往套合區2321滑移回去。 請參考「第3A圖」與「第3B圖」，其係為依據本發明之另 一風扇結構組合圖。承載板230具有裝卸孔231與至少一定位孔 232以及風扇承載面233。而風扇更包括風扇本體220以及風扇罩 240。風扇本體220具有氣體流通口 250，風扇罩240結合於風扇 本體220並且位於氣體流通口 250上，並且風扇罩240介於風扇 本體220與風扇承載面233之間。如前一實施態樣所述在風扇本 體220面對於風扇承載面233的侧面中設置與定位孔232數量相 同的固接組件221。在固接組件221的一端連接於風扇本體220， 而另·一端插設於定位孔232内。而且在固接組件221之插設於定 位孔232内的那一端更可以包覆避震墊26〇於其表面，藉以增加 風扇本體220與風扇固定結構21〇之連接穩定度。 另外，在風扇罩240相應卡抵組件212的位置上另設置一凸 塊241，卡抵組件212經由凸塊241抵靠於風扇本體22〇之側邊。 在此-實施態樣中係將卡抵組件212的連接端23()1仍是連接於承 載板230，而卡抵端2302則從風扇承載面233往風扇本體220的 方向彎’曲（如「第3A圖」所示）。在本實施態樣中，凸塊加的 延伸方向係與卡抵組件212所彎曲的方向相同，均為承載板230 的外側面234往風扇承載面233的方向延伸。 將風扇本體220的固接組件221個別的嵌入承載板23〇上對 驗置的定位孔232之套合區2321中。係分別由第一區塊261、 弟二區塊262與第三區塊263相串接，所形成的一定位結構。其 201245583 中’第-區塊261的截面積大於第二區塊262的截面積，且第三 區塊263的截面積大於第二區塊262的截面積。第一區塊的 截面積小於套合區232卜且第-區塊261的截面積大於連接區 2322與定位區2323。所以當把風扇本體22〇從套合區朝向 疋位區2323進行滑移的動作。如同前文所述，固接組件會被 固定在定位區助巾，使瓶扇本體22G也會翻定，並且固接 組件221亦可提供風扇本體220與承載板230間的緩衝作用。當 風扇本體220被固定時，凸塊241倾住卡抵組件212的前緣， 固定風扇本體220不會往聰移，因此風扇本體22()不會從定位 區2323往套合區2321方向滑動（如「第3B圖」所示）。如此一 來可以增加風扇本體220在在承載板23〇上的固定程度。如「第 3C圖」與「第3D圖」所示。 除了上述實施態樣外’本發明對卡抵組件212更提出一種增 加與風扇本體220側邊的卡抵面積的變化態樣。請參考「第4A圖」 第4D圖」所不’其係為本發明之第三種實施態樣示意圖與其 操作示意圖。 在「第4A圖」中，在卡抵組件212的卡抵端”犯處另設置 彎曲4 2121、曲部2121係由風扇承載φ 233往承載板23〇之斜 面2303的外側面234的方向彎曲出來，並切平風扇本體，的側 邊，使得卡抵組件212的卡抵端2302可以具有更大面積可以抵住 風扇本體220 °如同前文所述’風扇本體220在承載板230上滑過 的同時’風扇本體220會將卡抵組件212往承載板謂的外側面 201245583 234壓出，「第4C圖」。當風扇本體220在滑移到定位後，卡抵組 件212的卡抵端2302 (前述原本穿過裝卸孔231的卡抵端^犯） 由於沒有風扇本體220干涉，所以卡抵端23〇2會從外側面234朝 向風扇承載面233的方向回彈，使得卡抵組件212與風扇本體22〇 相對應的側邊會相抵住s所以風扇本體22〇將不會由定位區2323 往套合區2321滑移回去，「第4D圖」。 此外，也可以在彎曲部2121與風扇本體220的接觸面另設置 緩衝墊2122。當風扇本體220滑移至定位時使得彎曲部212丨經由 緩衝墊2122而抵靠於風扇本體220之側邊，請參考「第5圖」所 示，使得風扇本體220運行過程。當風扇本體22〇被導引到固定 位置時，卡抵組件212會抵靠於風扇本體220之一侧邊，進而將 風扇本體220被固定於承載板230上。所以相較於習知技術而言， 本發明的風扇固定機構210可以不需要額外的定位件（或螺絲） 即可將風扇本體固定於風扇固定機構21〇中。除了可以提高風扇 的組裝效率外’也可以降低風扇的組裝成本。 雖然本發明以前述之較佳實施例揭露如上，然其並非用以限 疋本發明’任何熟習相像技藝者，在不脫離本發明之精神和範圍 内.，當可作些許之更動與潤飾，因此本發明之專利保護範圍須視 本說明書所附之申請專利範圍所界定者為準。 【圖式簡單說明】

Description of the invention: [Technical field to which the invention pertains] - A fixed structure, particularly relating to a fan fixing mechanism. [Prior Art] With the high-light brain and rapid progress, various electronic components in the brain (such as a central processing unit (CPU), an integrated circuit (1〇) consume more and more heat, so the fan has been Wide range of lang, but with the increasing popularity of information and the amount of information processed, there is no doubt about the speed of future processing. Relatively, the heat dissipation of the processor is a problem that computer-related developers must face in the future. Since the electrons in the computer operate in a high temperature state τ, it is easy to cause instability. In order to make the electronic components stable and positive, it is necessary to effectively and quickly dissipate the heat generated by the electronic components. 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 broadcast can be quickly transmitted to the heat sink, or the heat can be removed by the fan in a forced convection manner to achieve the purpose of heat dissipation. Please refer to the "Figure 1" for the assembly of the fan of the prior art to the fan frame. The cooling fan 11G is installed in the fan frame m of the computer case. The fan cover m is disposed on both sides of the fan 110, and the fan cover m is fixed to the opposite sides of the cooling fan 110 by screws. The positioning member 112 is disposed on both sides of the cooling fan (10). The positioning member 112 further has The first buckle portion is out of the first buckle. P 114. The first to the N-port portion 113 is engaged with the fan cover ill to fix the positioning member 112 to the fan cover H1. 5 201245583 On both sides of the fan frame 120 When the heat dissipation fan 11 () is placed in the fan frame 120, the second fastening portion 114 is engaged with the buckle hole 121, so that the heat dissipation fan 110 is fixed to the fan frame 120. From the above, it is known that The cooling fan can be assembled on the fan frame through complicated components and combination process. Therefore, assembling the fan requires more manpower and man-hours. For the production line, g is a heavy burden. [Invention] The problem of the present invention is to provide a fan fixing mechanism that can be assembled quickly. The fan fixing mechanism disclosed in the present invention includes: a fan fixing mechanism and a fan; the fan fixing mechanism further includes a carrier plate and a card abutting component; The utility model further has a loading and unloading hole and at least one positioning hole and a fan bearing surface; and each positioning hole comprises at least a fitting area, a positioning area and a connecting area connecting the clamping area to the positioning area; each connecting area is formed by the nesting area The same-extending direction extends to the positioning area; the end of the card-receiving component is coupled to the carrier plate, and the card-receiving component extends in a direction opposite to the extending direction to pass the other end of the latching component through the loading and unloading hole and protrudes from the fan a bearing surface; a side of the fan has a fixing component of the same number as at least the positioning hole; the fan is located on the fan bearing surface, and at least the -HI connecting component is disposed at least in the positioning hole, and the clamping component abuts One side of the fan is connected to the carrier board based on the above-mentioned end of the 'mechanical card-receiving component extending to the positioning area due to the interlocking direction-extension direction. Therefore, through the guiding of the positioning hole, the contact member can bring the wind material to the fixed position by contacting the (4) nesting area, the vehicle area and the 201245583 bit area. In addition, since the card abutment assembly extends in a direction opposite to the extending direction such that the other wide edge of the latching assembly passes through the loading and unloading hole and protrudes from the fan bearing surface, the card is abutted when the fan is guided to the fixed position. The assembly abuts against one side of the fan to secure the fan to the carrier plate. Therefore, compared to the prior art, the above-described fan fixing mechanism does not require an additional positioning member to fix the fan thereto. Therefore, the combination of the above-described fan 0 fixed mechanism and the fan can not only improve the assembly efficiency of the fan, but also reduce the assembly cost of the fan. The features and implementations of the present invention are described in detail with reference to the preferred embodiments. [Embodiment] Please refer to "Figure 2A", which is a combination of fan structures 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 opposite ends, that is, a card abutting end 23〇2 and a connecting end 2301 connected to the carrier plate 230. The connecting end 2301 can be connected to the carrier plate 230 by 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 card abutment assembly 212 passes through the loading and unloading hole 231 (please refer to "B2B" 201245583). The area of the loading and unloading hole 231 is approximately larger than the engaging portion 212, so that the engaging end 2302 of the engaging member 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 latching 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 the fan body 220 and the fan cover 240. . The fan body 220 has a gas flow port 250'. The fan cover 240 is coupled to the fan body 220 and is 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 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. In addition, one end of the fixing component 221 inserted in the positioning hole 232 can be covered with the shock pad 26 , wherein the shock pad 260 is disposed between the fixing component 221 and the positioning hole 232 , thereby reducing the fan body 220 . Adverse effects on the fan fixing structure 21〇 during vibration. The appearance of the fixing assembly 221 is further described. 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 second block 2 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. 201245583, in the "2B figure" + four fixed components 221 as an example, so a number of four positioning holes are also arranged in the fan carrying plate 230, and the cross-sectional area of the nesting area is larger than the positioning area The cross-sectional area of the 2323 and the cross-sectional area of the first block 261 of the fixing assembly 221, the cross-sectional area of the positioning area 2323 is smaller than the cross-sectional area of the first block 261 of the fixing assembly 221. Hereinafter, the installation of the fan main body 22G will be described. Please refer to "2nd (:图)" 2D目"## respectively, which is a cross-sectional view before and after the fan is placed in the fixed structure according to the present invention. The fixing component 221 of the fan body 22 ( ) is embedded in the corresponding positioning hole of the carrier plate 230 in the clamping area 2321. The cross-sectional area of the 2321 is larger than the first block 261 of the fixing component 221 due to the fitting. The cross-sectional area of each of the connecting areas 2322 is extended by the nesting area 2321 along the same first direction 51〇 to the positioning area 2323' so that the fixing assembly 221 can slide toward the positioning area 2323. In other words, the fan body 22 can be slid from the splicing area 2321 to the positioning area 2323. Thereafter, since the cross-sectional area of the first block 261 of the fixing component 221 is larger than the connecting area 2322 and the fixed area of 2323, the fan body 22 () While the fan carrying surface 33 is π too far, the 'fan body 22' will pull the card abutting component ha toward the outer side surface 234 of the carrier plate 23' as shown in Fig. 2C. When the fan body is slipping After the positioning, the card offset component 212 is terminated by the card (the aforementioned original Since the end of the loading and unloading hole 231 does not interfere with the fan body 22, the card end 2 is rebounded from the outer side 234 toward the fan carrying surface 233, as shown in the "figure map", so that the card abutment component 212 It is in contact with the side of the fan body 22〇. Therefore, the fan body will not slide back the 201245583 from the positioning area 2323 to the nesting area 2321. Please refer to "3A" and "3B", which are based on Another fan structure combination diagram of 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, The fan cover 240 is 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 described in the previous embodiment, the fan body 220 faces the fan bearing surface. A fixing assembly 221 having the same number as the positioning hole 232 is disposed in the side surface of the 233. One end of the fixing assembly 221 is connected to the fan body 220, and the other end is inserted into the positioning hole 232. The end of the 221 that is inserted into the positioning hole 232 can cover the surface of the suspension pad 26 so as to increase the connection stability between the fan body 220 and the fan fixing structure 21. In addition, the fan cover 240 is correspondingly buckled. A bump 241 is further disposed at the position of the component 212. The latching component 212 abuts against the side of the fan body 22 via the bump 241. In this embodiment, the connecting end 23 of the latching component 212 is attached. 1 is still connected to the carrier plate 230, and the card abutting end 2302 is bent from the fan bearing surface 233 toward the fan body 220 (as shown in FIG. 3A). In this embodiment, the direction in which the bumps are applied 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 toward the fan bearing surface 233. The fixing assembly 221 of the fan body 220 is individually embedded in the nesting area 2321 of the positioning hole 232 of the mounting plate 23. 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 'block 261' in 201245583 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 is smaller than the fit area 232 and the cross-sectional area of the first block 261 is larger than the connection area 2322 and the positioning area 2323. Therefore, the action of sliding the fan body 22 from the nesting area toward the clamping area 2323 is performed. As described above, the fixing assembly is fixed to the positioning area of the towel so that the bottle body 22G is also turned over, and the fixing member 221 can also provide a buffer between the fan body 220 and the carrier plate 230. When the fan body 220 is fixed, the protrusion 241 tilts the front edge of the card abutting component 212, and the fixed fan body 220 does not move, so the fan body 22 does 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 23 can be increased. For example, "3C" and "3D". In addition to the above-described embodiments, the present invention further proposes a variation of the card abutment area of the fan body 220. Please refer to Fig. 4A, Fig. 4D, and Fig. 4 is a schematic view showing a third embodiment of the present invention and its operation. In the "Fig. 4A", the bending of the card abutting portion 212 is further provided with a bending 4212, and the curved portion 2121 is bent by the fan bearing φ 233 toward the outer side surface 234 of the inclined surface 2303 of the carrier plate 23〇. And the side edges of the fan body are cut out, so that the card abutting end 2302 of the card abutting component 212 can have a larger area to resist the fan body 220° as the fan body 220 slides over the carrier plate 230 as described above. At the same time, the fan body 220 pushes the card abutment assembly 212 toward the outer side surface 201245583 234 of the carrier board, "4C". After the fan body 220 is slid to the position, the card abutting end 2302 of the card abutting component 212 (the aforementioned card abutting end that passes through the loading and unloading hole 231) does not interfere with the fan body 220, so the card end 23〇2 will Rebound from the outer side 234 toward the fan bearing surface 233, so that the side of the card abutment assembly 212 corresponding to the fan body 22 会 will resist s, so the fan body 22 will not be moved from the positioning area 2323 to the tying area 2321 Slide back, "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 position, the bending portion 212 is abutted against the side of the fan body 220 via the cushion 2122. Referring to FIG. 5, the fan body 220 is operated. When the fan body 22 is guided to the fixed position, the card abutment assembly 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 21〇 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. Although the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the invention to those skilled in the art, and may be modified and modified without departing from the spirit and scope of the invention. Therefore, the scope of patent protection of the present invention is defined by the scope of the claims appended hereto.
