圖1為一種習知風扇中的馬達的部分分解示意圖。如圖1 所示，於風扇的生產過程中，組裝時必須使矽鋼片組（圖 未示）及定子座12穩固地與馬達底座上之軸管11接合。 [0004] 習知的接合方式係將膠水塗佈在轴管11的外周緣，再將 定子座12及矽鋼片組分別套設於軸管11，等待膠水固化 後定子座12即與軸管11接合固定。 [0005] 然而，於點膠製程中常發生漏點膠、膠量過少或過多的 狀況，且因點膠設備的維護不易，停機維護時更常造成 膠水的浪費。此外，膠水的固化時間相當長，還須考慮 膠水的固化參數對於結合品質的影響。以上總總問題， 不僅造成組裝上的不便，也使得馬達的製程效率不易提 升。 [0006] 因此，如何提供一種馬達，其能簡化組裝流程，同時節 省點膠製程之所需成本，進而達到提高生產效率並降低 表單編號A0101 第3頁/共19頁 製造成本的目的，已成為重要課題之一。

組合示意圖，圖4係為圖3所示之馬達2的剖面示意圖。請 參照圖2A，馬達2包括一軸管21、一定子座22以及一轉子 結構23(圖4)，於此，係以一種應用於散熱風扇的馬達2 為例繪圖說明，並且，為了清楚顯示本創作之技術特徵 ，於圖2A、圖2B及圖3中僅繪示出馬達2之轴管21及定子 座22，而有關轉子結構23之態樣則請參考圖4所示。以下 先主要以馬達2於熱熔製程前之構造說明。 [0020] 轴管21的頂端211設置至少一第一接合部212，於此係以 表單編號A0101 第6頁/共19頁 複數個第一接合部212為例說明，第一接合部212可為凸 型結構，例如但不限於為矩形、三角形、半圓形、多邊 形或不規則形的突起結構，於此係以第一接合部212呈矩 形突起的凸型結構為例。 [0021] 定子座22具有一内襯221，馬達2具有一矽鋼片組25，插 設於内襯221。内襯221為絕緣框架，矽鋼片組25係供繞 線組（圖未顯示）繞設。内襯221的中央處具有一開孔 222，並且定子座22係藉由開孔222而與矽鋼片組25分別 套設於軸管21。其中，内襯221於開孔222的周緣設置有 至少一第二接合部223，第二接合部223與第一接合部 212對應設置，並與第一接合部212熱熔連結。第二接合 部223可為凹型結構，例如但不限於矩形、三角形、半圓 形、多邊形或不規則形的凹槽結構。於此，定子座22係 以具有四個第二接合部223為例說明，而實際設計上，第 二接合部223的設置位置及數量皆係與第一接合部212對 應設置，並不限制須具有特定的設置位置或數量。 [0022] 如圖4所示，轉子結構23係由定子座22所驅動，轉子結構 23具有一轉抽231，轉軸231軸設於軸管21。進一步而言 ，軸管21與轉軸231之間設有軸承B，軸承B的潤滑油可減 少轉軸231轉動時產生的磨擦力，進而降低轉軸231的磨 損。 [0023] 在定子座22套設於軸管21後，定子座22的内襯221上之 第二接合部223與軸管21的第一接合部212對應設置，始 進行第二接合部223與第一接合部212的熱熔連結。須特 別說明的是，圖2A及圖2B顯示之馬達2皆為其於熱熔製程 表單編號A0101 第7頁/共19頁 M419336 前的結構，當第一接合部212與第二接合部223進行熱熔 連結時，第一接合部212因本身被熱熔而導致變形而可實 質上填入第二接合部223。於此所稱實質上填入，是指第 一接合部212(凸型結構）可完全填滿第二接合部223(凹 型結構），或者第一接合部212(凸型結構）並未完全填滿 第二接合部223(凹型結構）。本領域具有通常知識者當知 ，無論是否完全填滿，只要第一接合部212因熱熔變形而 填入第二接合部223，均可使二構件達到連結。 [0024] 因而如圖3所示，於本實施例中，軸管21的第一接合部 212於冷卻固化後，實質上填平定子座22的内襯221上之 第二接合部223的凹型結構，其僅為舉例非可用以限制本 創作。其中，第一接合部212的材質為熱塑性材料，例如 但不限於塑膠，例如可為聚氯乙烯（PVC)或聚對苯二甲 酸乙二酯（PET)。而在較佳實施例中，第一接合部212 、第二接合部223、軸管21及内襯221可為相同的材質， 且第一接合部212可與軸管21—體成型製成，第二接合部 223可與内襯221 —體成型製成。 [0025] 需強調的是，雖本實施例中係以第一接合部2 12為凸型結 構、第二接合部223為凹型結構為例，但在實際設計上， 第一接合部212與第二接合部223亦可分別為凹型結構與 凸型結構、或粗糙結構與粗糙結構的方式對應設置。具 體而言，當第一接合部為凹型結構時，第二接合部為凸 型結構，第二接合部可變形且實質上填入第一接合部， 以達到緊密地連結。當第一接合部為粗糙結構時，第二 接合部同樣為粗糙結構，第一接合部及/或第二接合部可 表單編號A0101 第8頁/共19頁 變形且實質上填入第二接合部及/或第一接合部，以達到 緊密地連結。 [0026] 請同時參照圖3及圖4所示，因熱熔後的第一接合部212向 軸管21外徑延伸連結第二接合部223，又第二接合部223 的結構設計使固化後的第一接合部212能卡合於第二接合 部223的凹型結構，故藉由熱熔連結後的第一接合部212 與第二接合部223，具有熱熔連結及結構配合的雙重作用 ，可防止轴管21及與定子座22間相對的軸轉方向D1移動 與順/逆時針方向D2的轉動，進而達成軸管21與定子座22 之間的穩固連結。 [0027] 此外，值得一提的是，如圖2A、圖2B及圖4所示，馬達2 的第一接合部212與第二接合部223的熱熔連結製程，更 可與習知油封24與軸管21的熱熔連結同時進行。詳而言 之，習知油封24以熱熔連結方式設置於軸管21的頂端211 的内周緣，用以防止轉子結構23的轉軸231與軸管21内的 潤滑油揮發。因此，本創作之馬達2的組裝過程，係將油 封24設置於軸管21的頂端211的内周緣，且定子座22套 設於軸管21後，即進行熱熔連結製程，從而可同時完成 軸管21、定子座22及油封24之間的固定連結，以達簡化 製程的功效。 [0028] 圖5為圖2A所示之另一視角的定子座22的示意圖，因圖2A 所示角度的關係，並未顯示開孔222内周緣的凹部224， 故於圖5中將圖2A的整體定子座22旋轉大約180度的視角 ，以方便說明，故以下請同時參考圖2A及圖5所示。 [0029] 為了讓定子座22套設於軸管21時能準確地定位，俾使第 表單編號A0101 第9頁/共19頁 M419336 一接合部212與第二接合部223的位置能夠對應設置，軸 管21的外周緣還可具有至少一凸部213，而定子座22的開 孔222的内周緣也可具有與凸部213相對應的至少一凹部 224 ’當定子座22套設於轴管21時，凸部213可與凹部 224緊密接合。於此，軸管211的外周緣係以設有二凸部 213

New Description: [New Technology Field] [0001] This paper is about a motor and a fan, especially a motor and a fan with a heat-fixing structure. [Prior Art] [0002] As the power consumption of electronic components continues to increase, heat dissipation problems in various electronic devices are gradually gaining attention. In the industry, heat sinks such as fans are usually installed in electronic devices for electronic components. The generated heat is dissipated from the electronic device by the airflow generated by the fan, thereby achieving the purpose of heat dissipation. [0003] FIG. 1 is a partially exploded perspective view of a motor in a conventional fan. As shown in Fig. 1, during the production of the fan, the silicon steel sheet set (not shown) and the stator base 12 must be firmly engaged with the shaft tube 11 on the motor base during assembly. [0004] The conventional joining method is to apply glue to the outer circumference of the shaft tube 11, and then the stator seat 12 and the silicon steel sheet set are respectively sleeved on the shaft tube 11, and the stator seat 12 and the shaft tube 11 are awaited after the glue is solidified. The joint is fixed. [0005] However, in the dispensing process, leakage of glue, excessive or excessive amount of glue often occurs, and the maintenance of the dispensing equipment is not easy, and the glue is often wasted during shutdown maintenance. In addition, the curing time of the glue is quite long, and the influence of the curing parameters of the glue on the bonding quality must also be considered. The above total problem not only causes inconvenience in assembly, but also makes the process efficiency of the motor difficult to increase. [0006] Therefore, how to provide a motor that simplifies the assembly process while saving the cost of the dispensing process, thereby achieving the purpose of improving production efficiency and reducing the manufacturing cost of the form number A0101, page 3/19 pages, has become One of the important topics. [New Content] [0007] In view of the above problems, the purpose of the present invention is to provide a motor and a fan, which can simplify the assembly process and save the cost of the dispensing process, thereby achieving the purpose of improving production efficiency and reducing manufacturing cost. In order to achieve the above object, a motor according to the present invention comprises a shaft tube, a stator and a rotor structure. The top end of the shaft tube is provided with at least one first joint portion; the stator seat has an inner liner, and the inner portion of the inner liner has an opening, the stator seat is sleeved on the shaft tube by the opening, and the inner liner is disposed at least on the periphery of the opening a second joint portion, the second joint portion is disposed corresponding to the first joint portion, and is thermally coupled to the first joint portion. The rotor structure has a rotating shaft, and the rotating shaft is disposed on the shaft tube. [0009] In order to achieve the above object, a fan according to the present invention includes an impeller and a motor, and the motor is coupled to drive the impeller to rotate. The motor includes a shaft tube, a stator block, and a rotor structure. The top end of the shaft tube is provided with at least one first joint portion; the stator seat has an inner liner, and the inner portion of the inner liner has an opening, the stator seat is sleeved on the shaft tube by the opening, and the inner liner is disposed at least on the periphery of the opening a second joint portion, the second joint portion is disposed corresponding to the first joint portion, and is thermally coupled to the first joint portion. The rotor structure has a rotating shaft, and the rotating shaft is disposed on the shaft tube. [0010] In an embodiment, the outer circumference of the shaft tube may have at least one convex portion, and the circumference of the opening may further have at least one concave portion corresponding to the convex portion, and the convex portion and the concave portion are closely engaged. [0011] In an embodiment, the first joint portion and the second joint portion may be disposed corresponding to the convex structure form number A0101, the fourth page, or the 19th portion, and the rough structure and the rough structure. When the first joint portion has a convex structure, the second joint portion has a concave structure; or, when the first joint portion has a concave structure, the second joint portion has a convex structure. When the first joint portion is a rough structure, the second joint portion is also a raw sugar structure. [0012] In an embodiment, after the first joint portion and the second joint portion are thermally fused, the first joint portion is deformable and substantially filled with the second joint portion to be tightly joined. Alternatively, the second joint may be deformed and substantially filled into the first joint, again to achieve a tight joint. [0013] In an embodiment, the material of the first joint portion and the second joint portion may be a thermoplastic material such as, but not limited to, plastic. The material of the inner tube of the shaft tube and the stator seat can also be a thermoplastic material such as plastic. [0014] In an embodiment, the motor may further include an oil seal disposed on an inner circumference of the top end of the shaft tube, and the oil seal may be thermally coupled to the first joint portion and the second joint portion. [0015] In an embodiment, the above motor can be applied to an axial fan or a centrifugal fan. [0016] According to the above description, the motor and the fan according to the present invention can stabilize the shaft tube and the stator seat by the heat fusion connection between the first joint portion of the shaft tube and the second joint portion on the inner liner of the stator seat. Ground connection. Compared with the prior art, since the shaft tube and the stator seat of the motor of the present invention are not used for dispensing, it is not necessary to bear the equipment cost of the dispenser, the labor cost required for the dispensing process, and the glue used for dispensing. Material cost can effectively reduce the manufacturing cost of the motor. Moreover, the shortcomings of the conventional dispensing process, such as: leaking glue, form number A0101, page 5 / 19 pages, M419336, too little or too much glue, difficult maintenance of dispensing equipment, and waste of glue during downtime maintenance, etc. Can be improved. Furthermore, the strength of the connection between the shaft tube and the stator seat can be enhanced. [0017] In addition, the manufacturing process of the motor does not require a long time to wait for the curing of the glue, and it is no longer necessary to consider the influence of the curing parameters of the glue on the quality of the joint. In addition, since the hot-melt joining process of the first joint portion and the second joint portion can be combined with the original oil seal process and the stator seat, the shaft tube, and the oil seal are connected at the same time, the motor of the present invention is not only helpful. The simplification of the process can also greatly increase the speed and efficiency of the mass production of the motor. [Embodiment] A motor and a fan according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings, wherein like elements will be described with the same reference numerals. 2A is a partial exploded view of the motor 2 according to the present invention before the hot melt process, FIG. 2B is a partial assembly diagram of the motor 2 shown in FIG. 2A before the hot melt process, and FIG. 3 is a schematic view of the motor 2 shown in FIG. FIG. 4 is a schematic cross-sectional view of the motor 2 shown in FIG. 3, which is a schematic view of a portion of the motor 2 after the hot melt process. Referring to FIG. 2A, the motor 2 includes a shaft tube 21, a stator block 22, and a rotor structure 23 (FIG. 4). Here, a motor 2 applied to the heat dissipation fan is illustrated as an example, and the present invention is clearly shown. The technical features of the creation, only the shaft tube 21 and the stator base 22 of the motor 2 are shown in Figs. 2A, 2B and 3, and the state of the rotor structure 23 is shown in Fig. 4. The following is mainly based on the construction of the motor 2 prior to the hot melt process. [0020] The top end 211 of the shaft tube 21 is provided with at least one first joint portion 212. Here, the first joint portion 212 is exemplified by a form number A0101, a sixth joint page, and a first joint portion 212. The convex structure, for example, but not limited to, a rectangular, triangular, semi-circular, polygonal or irregular shaped protruding structure, is exemplified by a convex structure in which the first joint portion 212 has a rectangular protrusion. [0021] The stator base 22 has a lining 221, and the motor 2 has a set of silicon steel sheets 25 that are inserted into the inner liner 221. The inner liner 221 is an insulating frame, and the silicon steel sheet set 25 is wound around a winding group (not shown). The inner lining 221 has an opening 222 at the center thereof, and the stator base 22 is sleeved with the silicon steel sheet set 25 on the shaft tube 21 by the opening 222. The inner liner 221 is provided with at least one second joint portion 223 at the periphery of the opening 222. The second joint portion 223 is disposed corresponding to the first joint portion 212 and is thermally coupled to the first joint portion 212. The second joint portion 223 may be a concave structure such as, but not limited to, a rectangular, triangular, semi-circular, polygonal or irregular shaped groove structure. Herein, the stator base 22 is exemplified by having four second joint portions 223. Actually, the position and the number of the second joint portions 223 are correspondingly arranged with the first joint portion 212, and the limitation is not limited. Have a specific set location or number. As shown in FIG. 4, the rotor structure 23 is driven by the stator base 22, the rotor structure 23 has a rotary 231, and the rotating shaft 231 is axially disposed on the shaft tube 21. Further, a bearing B is provided between the shaft tube 21 and the rotating shaft 231, and the lubricating oil of the bearing B can reduce the frictional force generated when the rotating shaft 231 rotates, thereby reducing the wear of the rotating shaft 231. [0023] After the stator seat 22 is sleeved on the shaft tube 21, the second joint portion 223 on the inner liner 221 of the stator seat 22 is disposed corresponding to the first joint portion 212 of the shaft tube 21, and the second joint portion 223 is started. The first joint portion 212 is thermally fused. It should be particularly noted that the motor 2 shown in FIG. 2A and FIG. 2B is the structure before the hot-melt process form number A0101, page 7 / 19 pages, M419336, when the first joint portion 212 and the second joint portion 223 are performed. At the time of heat fusion bonding, the first joint portion 212 is deformed by heat fusion itself, and can be substantially filled in the second joint portion 223. As used herein, substantially filled means that the first joint portion 212 (convex structure) can completely fill the second joint portion 223 (concave structure), or the first joint portion 212 (convex structure) is not completely filled. The second joint portion 223 is filled (concave structure). It is known to those skilled in the art that the two members can be joined as long as the first joint portion 212 is filled with the second joint portion 223 by heat fusion deformation, whether or not it is completely filled. [0024] Thus, as shown in FIG. 3, in the present embodiment, the first joint portion 212 of the shaft tube 21 substantially fills the concave shape of the second joint portion 223 on the inner liner 221 of the stator seat 22 after being solidified by cooling. Structure, which is merely non-useable to limit the creation. The material of the first joint portion 212 is a thermoplastic material, such as but not limited to plastic, and may be, for example, polyvinyl chloride (PVC) or polyethylene terephthalate (PET). In the preferred embodiment, the first joint portion 212, the second joint portion 223, the shaft tube 21 and the inner liner 221 may be of the same material, and the first joint portion 212 may be integrally formed with the shaft tube 21. The second joint portion 223 may be formed integrally with the inner liner 221. [0025] It should be emphasized that in the embodiment, the first joint portion 2 12 has a convex structure and the second joint portion 223 has a concave structure. However, in actual design, the first joint portion 212 and the first joint portion 212 The two joint portions 223 may also be provided in a manner corresponding to a concave structure and a convex structure, or a rough structure and a rough structure, respectively. Specifically, when the first engaging portion is of a concave configuration, the second engaging portion is a convex structure, and the second engaging portion is deformable and substantially filled with the first engaging portion to achieve tight joint. When the first joint portion is a rough structure, the second joint portion is also a rough structure, and the first joint portion and/or the second joint portion can be deformed by the form number A0101, page 8 of 19 and substantially filled with the second joint. And/or the first joint to achieve a tight connection. Referring to FIG. 3 and FIG. 4 simultaneously, the first joint portion 212 after the hot melt extends the second joint portion 223 to the outer diameter of the shaft tube 21, and the second joint portion 223 is designed to be solidified. The first joint portion 212 can be engaged with the concave structure of the second joint portion 223. Therefore, the first joint portion 212 and the second joint portion 223 after the heat fusion joint have the dual functions of heat fusion joint and structural joint. The rotation of the shaft tube 21 and the stator shaft 22 in the direction of the rotation D1 and the rotation in the forward/counterclockwise direction D2 can be prevented, and the stable connection between the shaft tube 21 and the stator holder 22 can be achieved. [0027] In addition, as shown in FIG. 2A, FIG. 2B and FIG. 4, the hot-melt joining process of the first joint portion 212 and the second joint portion 223 of the motor 2 can be further matched with the conventional oil seal 24. Simultaneously with the heat fusion bonding of the shaft tube 21. More specifically, the conventional oil seal 24 is disposed on the inner periphery of the tip end 211 of the shaft tube 21 by heat fusion to prevent the lubricating oil in the shaft 231 of the rotor structure 23 from being volatilized in the shaft tube 21. Therefore, in the assembly process of the motor 2 of the present invention, the oil seal 24 is disposed on the inner periphery of the top end 211 of the shaft tube 21, and the stator seat 22 is sleeved on the shaft tube 21, that is, the hot-melt joint process is performed, thereby simultaneously completing The fixed connection between the shaft tube 21, the stator seat 22 and the oil seal 24 is to simplify the process. 5 is a schematic view of the stator seat 22 of another angle of view shown in FIG. 2A. Because of the angle relationship shown in FIG. 2A, the recess 224 of the inner circumference of the opening 222 is not shown, so FIG. 2A is shown in FIG. The overall stator base 22 is rotated by an angle of view of about 180 degrees for convenience of explanation, so please refer to FIG. 2A and FIG. 5 below. [0029] In order to accurately position the stator seat 22 when it is sleeved on the shaft tube 21, the position of the joint portion 212 and the second joint portion 223 of the first form number A0101, page 9/19, M419336 can be correspondingly set. The outer circumference of the shaft tube 21 may further have at least one convex portion 213, and the inner circumference of the opening 222 of the stator seat 22 may also have at least one concave portion 224 corresponding to the convex portion 213. When the stator seat 22 is sleeved on the shaft tube At 21 o'clock, the convex portion 213 can be in close engagement with the concave portion 224. Here, the outer circumference of the shaft tube 211 is exemplified by two convex portions 213 ′ and the convex portion 213 is a rectangular or circular rib, and the shape, size, number, and arrangement position of the concave portion 224 are both opposite to the convex portion 213 . Correspondingly, the inner circumference of the opening 222 is a rectangular or circular groove having two concave portions 224 and the concave portion 224 is a corresponding convex portion 213. Of course, the present invention does not limit the convex portion 213 and The recess 224 is of a structural design as long as the stator seat 22 and the shaft tube 21 can be positioned. [0030] It should be noted that the motor 2 designed with the convex portion 213 and the concave portion 224, the stator seat 22 and the shaft tube 21 can be engaged with the concave portion 224 by the convex portion 213 in addition to the above-mentioned heat-fused joint fixing structure. Further, the firmness of the connection between the two is enhanced. [0031] As shown in FIG. 4, the motor 2 can be disposed in the fan as a driving source for driving the impeller, and the fan includes the impeller and the motor 2, and the motor 2 is constructed. It has been described in detail above and will not be described here. Since the impeller is connected by the rotor structure 23 and the blade BL, the impeller can be rotated when the motor 2 is operated. [0032] In summary, the motor and the fan according to the present invention can stabilize the shaft tube and the stator seat by the heat fusion connection between the first joint portion of the shaft tube and the second joint portion on the inner liner of the stator seat. Ground connection. Compared with the prior art, the shaft tube and the stator seat of the motor of the present invention do not need to use the dispensing process, so the equipment cost of the dispenser and the labor cost required for the dispensing process are not required. Form No. 1010101 The material cost of the 10 pages/19 pages and the glue used for dispensing can effectively reduce the manufacturing cost of the motor. Moreover, the shortcomings of the conventional dispensing process, such as leakage dispensing, too little or too much, poor maintenance of the transfer equipment, protection of "water waste, etc." can be improved. Furthermore, the strength of the connection between the wheel tube and the stator can be enhanced. [0033] In addition, the creation of the motor does not require a long time to wait for the curing of the knee water, and it is not necessary to test the effect of the curing parameter of water on the quality of the joint. In addition, since the "joining process" of the first joint portion and the second joint portion can also be combined with the original oil seal process, and the connection of the stator seat, the shaft tube, and the oil seal is at the same time, the motor of the present creation not only contributes to the process. The simplification of the _ can also greatly increase the speed and efficiency of the mass production of the motor.
