Description
本發明係關於一種電子裝置，特別是一種具有風流產生器之電子裝置。The present invention relates to an electronic device, and more particularly to an electronic device having a wind flow generator.
習知電子裝置中，常以風扇等風流產生器進行散熱。當使用者使用電子裝置時，手部常會推壓電子裝置，使得電子裝置之外殼變形。當電子裝置之外殼變形時，常會一併擠壓到電子裝置內部的風扇。導致電子裝置之外殼有很大的面積會接觸到風扇。In conventional electronic devices, heat is often dissipated by a wind flow generator such as a fan. When the user uses the electronic device, the hand often pushes the electronic device to deform the outer casing of the electronic device. When the outer casing of the electronic device is deformed, the fan inside the electronic device is often squeezed together. This causes the outer casing of the electronic device to have a large area to contact the fan.
當風扇受到大面積外殼的擠壓時，外殼會對風扇產生極大的摩擦力及摩擦力矩。因此導致風扇的轉速降低及噪音增加，進而導致風扇的散熱效率降低。When the fan is squeezed by a large area of the casing, the casing will generate a great friction and friction torque to the fan. As a result, the rotation speed of the fan is reduced and the noise is increased, which in turn causes the heat dissipation efficiency of the fan to decrease.
有鑑於以上的問題，本發明提出一種電子裝置，藉以改善風流產生器受壓時之轉速及散熱效率。In view of the above problems, the present invention provides an electronic device for improving the rotational speed and heat dissipation efficiency of a wind flow generator when it is pressurized.
本發明揭露一種電子裝置，包括一殼體、一風流產生器及一支撐凸塊。殼體具有一抵靠面位於殼體內。風流產生器設置於殼體內。風流產生器包括一輪軸部及多個扇葉。扇葉設置於輪軸部之周圍。支撐凸塊設置於輪軸部及抵靠面之一者，且朝 向輪軸部及抵靠面之另一者凸起。換言之，若支撐凸塊設置於輪軸部，則支撐凸塊朝向抵靠面凸起。又，若支撐凸塊設置於抵靠面，則支撐凸塊朝向輪軸部凸起。The invention discloses an electronic device comprising a casing, a wind flow generator and a supporting protrusion. The housing has an abutment surface located within the housing. The air flow generator is disposed in the housing. The airflow generator includes a wheel axle portion and a plurality of blades. The fan blade is disposed around the axle portion. The support protrusion is disposed on one of the axle portion and the abutting surface, and Projecting to the other of the axle portion and the abutment surface. In other words, if the support projection is provided on the axle portion, the support projection is convex toward the abutment surface. Further, if the support projection is provided on the abutment surface, the support projection is convex toward the axle portion.
根據本發明之電子裝置，能夠在殼體受壓時，藉由支撐凸塊使殼體與風流產生器以點的方式接觸，而能避免大面積之殼體擠壓風流產生器。藉此，即使殼體受到外力壓迫，風流產生器所受到的摩擦力及摩擦力矩也能夠降至最低，以避免風流產生器之流速下降，而能夠維持風流產生器之散熱效率。According to the electronic device of the present invention, it is possible to contact the airflow generator in a point manner by supporting the bumps when the casing is pressed, and it is possible to prevent the large-area casing from squeezing the airflow generator. Thereby, even if the casing is pressed by an external force, the frictional force and the friction torque received by the airflow generator can be minimized to avoid the flow velocity of the airflow generator being lowered, and the heat dissipation efficiency of the airflow generator can be maintained.
以上之關於本發明內容之說明及以下之實施方式之說明係用以示範與解釋本發明之精神與原理，並且提供本發明之專利申請範圍更進一步之解釋。The above description of the present invention and the following description of the embodiments of the present invention are intended to illustrate and explain the spirit and principles of the invention.

以下在實施方式中詳細敘述本發明之詳細特徵以及優點，其內容足以使任何本領域中具通常知識者了解本發明之技術內容並據以實施，且根據本說明書所揭露之內容、申請專利範 圍及圖式，任何本領域中具通常知識者可輕易地理解本發明相關之目的及優點。以下之實施例係進一步詳細說明本發明之觀點，但非以任何觀點限制本發明之範疇。The detailed features and advantages of the present invention are described in detail below in the embodiments of the present invention. The objects and advantages associated with the present invention are readily understood by those of ordinary skill in the art. The following examples are intended to describe the present invention in further detail, but are not intended to limit the scope of the invention.
請參照第1圖，繪示依照本發明之實施例之電子裝置1之剖面圖。於本實施例中，電子裝置1包括一殼體11、一風流產生器12、一支撐凸塊13及一鍵盤14。殼體11具有一抵靠面11a位於殼體11內。殼體11包括一鍵盤支撐件111，用以承載鍵盤14。抵靠面11a位於鍵盤支撐件111。Referring to FIG. 1, a cross-sectional view of an electronic device 1 in accordance with an embodiment of the present invention is shown. In this embodiment, the electronic device 1 includes a housing 11 , a wind flow generator 12 , a support protrusion 13 , and a keyboard 14 . The housing 11 has an abutment surface 11a located within the housing 11. The housing 11 includes a keyboard support 111 for carrying the keyboard 14. The abutment surface 11a is located on the keyboard support 111.
風流產生器12設置於殼體11內。風流產生器12包括一輪軸部121、多個扇葉122及一框架123。扇葉122設置於輪軸部121之周圍。框架123設置於輪軸部121及扇葉122之周圍。鍵盤支撐件111位於鍵盤14及風流產生器12之間。The air flow generator 12 is disposed inside the casing 11. The airflow generator 12 includes an axle portion 121, a plurality of blades 122, and a frame 123. The blade 122 is disposed around the axle portion 121. The frame 123 is disposed around the axle portion 121 and the blade 122. The keyboard support 111 is located between the keyboard 14 and the airflow generator 12.
支撐凸塊13設置於輪軸部121，且朝向抵靠面11a凸起。支撐凸塊13之形狀為錐狀。支撐凸塊13位於輪軸部121之旋轉中心。The support protrusion 13 is provided on the axle portion 121 and protrudes toward the abutting surface 11a. The shape of the support bump 13 is tapered. The support projection 13 is located at the center of rotation of the axle portion 121.
因此，當使用鍵盤14時，使用者會對鍵盤14及鍵盤支撐件111施加壓力，使鍵盤支撐件111之抵靠面11a與支撐凸塊13接觸。由於鍵盤支撐件111及支撐凸塊13間為點的接觸，且二者之接觸位置位於輪軸部121之旋轉中心，而能減少鍵盤支撐件111及支撐凸塊13之間的摩擦力及摩擦力矩，進而避免風流產生器12的轉速下降，以維持風流產生器12之風流產生功能。Therefore, when the keyboard 14 is used, the user applies pressure to the keyboard 14 and the keyboard support 111 such that the abutment surface 11a of the keyboard support 111 comes into contact with the support bumps 13. Since the contact between the keyboard support member 111 and the support protrusions 13 is point, and the contact positions of the two are located at the center of rotation of the axle portion 121, the friction and friction between the keyboard support member 111 and the support protrusions 13 can be reduced. Further, the rotation speed of the air flow generator 12 is prevented from being lowered to maintain the air flow generating function of the air flow generator 12.
請參照第2圖，繪示依照本發明之另一實施例之電 子裝置2之剖面圖。電子裝置2與第1圖所示之電子裝置1相似，故在此僅就兩實施例之差異進行說明。於本實施例中，殼體21包括一底部212。抵靠面21a位於底部212。風流產生器22位於鍵盤24及底部212之間。Please refer to FIG. 2, which illustrates another embodiment of the present invention. A cross-sectional view of the sub-device 2. The electronic device 2 is similar to the electronic device 1 shown in Fig. 1, and therefore only the differences between the two embodiments will be described. In the present embodiment, the housing 21 includes a bottom portion 212. The abutment surface 21a is located at the bottom 212. The airflow generator 22 is located between the keyboard 24 and the bottom 212.
因此，當使用鍵盤24時，使用者會對鍵盤24及鍵盤支撐件211施加壓力，進而對風流產生器22施加壓力，使得位於風流產生器22之輪軸部221之支撐凸塊23與底部212之抵靠面21a接觸。由於支撐凸塊23及殼體21之底部212間為點的接觸，且二者之接觸位置位於輪軸部221之旋轉中心，而能減少支撐凸塊23及殼體21之底部212之間的摩擦力及摩擦力矩，進而避免風流產生器22的轉速下降，以維持風流產生器22之風流產生功能。Therefore, when the keyboard 24 is used, the user applies pressure to the keyboard 24 and the keyboard support 211, thereby applying pressure to the airflow generator 22, so that the support projection 23 and the bottom 212 of the axle portion 221 of the airflow generator 22 are placed. The abutting surface 21a is in contact. Since the contact bump 23 and the bottom 212 of the housing 21 are in point contact, and the contact positions of the two are located at the center of rotation of the axle portion 221, the friction between the support projection 23 and the bottom 212 of the housing 21 can be reduced. The force and the frictional torque, in turn, prevent the rotational speed of the airflow generator 22 from decreasing to maintain the airflow generating function of the airflow generator 22.
請參照第3圖，繪示依照本發明之另一實施例之電子裝置3之剖面圖。電子裝置3與第1圖所示之電子裝置1相似，故在此僅就兩實施例之差異進行說明。於本實施例中，支撐凸塊33設置於殼體31之鍵盤支撐件311之抵靠面31a，且朝向輪軸部321凸起。輪軸部321具有一凹部321a，位於輪軸部321之旋轉中心。支撐凸塊321朝向凹部321a。Referring to FIG. 3, a cross-sectional view of an electronic device 3 in accordance with another embodiment of the present invention is shown. The electronic device 3 is similar to the electronic device 1 shown in Fig. 1, and therefore only the differences between the two embodiments will be described. In the present embodiment, the support protrusion 33 is disposed on the abutting surface 31a of the keyboard support 311 of the housing 31 and protrudes toward the axle portion 321 . The axle portion 321 has a recess 321a located at the center of rotation of the axle portion 321 . The support bump 321 faces the recess 321a.
因此，當使用鍵盤34時，使用者會對鍵盤34及鍵盤支撐件311施加壓力，使設置於鍵盤支撐件311之抵靠面31a之支撐凸塊33與風流產生器32之輪軸部321接觸。更甚者，支撐凸塊33能與輪軸部321之凹部321a之壁面接觸，使得支撐凸 塊33與輪軸部321之接觸位置位於輪軸部321之旋轉中心。由於支撐凸塊33與輪軸部321間為點的接觸，且二者之接觸位置位於輪軸部321之旋轉中心，而能減少支撐凸塊33及輪軸部321之間的摩擦力及摩擦力矩，進而避免風流產生器32的轉速下降，以維持風流產生器32之風流產生功能。Therefore, when the keyboard 34 is used, the user applies pressure to the keyboard 34 and the keyboard support member 311 to bring the support projections 33 provided on the abutting surface 31a of the keyboard support member 311 into contact with the axle portion 321 of the airflow generator 32. Furthermore, the support protrusion 33 can be in contact with the wall surface of the recess 321a of the axle portion 321 so that the support protrusion The contact position of the block 33 with the axle portion 321 is located at the center of rotation of the axle portion 321 . Since the contact between the support protrusion 33 and the axle portion 321 is point contact, and the contact position between the two supports is located at the center of rotation of the axle portion 321 , the frictional force and the friction torque between the support projection 33 and the axle portion 321 can be reduced. The rotation speed of the air flow generator 32 is prevented from dropping to maintain the air flow generating function of the air flow generator 32.
請參照第4圖，繪示依照本發明之另一實施例之電子裝置4之剖面圖。電子裝置4與第3圖所示之電子裝置3相似，故在此僅就兩實施例之差異進行說明。於本實施例中，殼體41包括一底部412。抵靠面41a位於底部412。風流產生器42位於鍵盤44及底部412之間。Referring to FIG. 4, a cross-sectional view of an electronic device 4 in accordance with another embodiment of the present invention is shown. The electronic device 4 is similar to the electronic device 3 shown in Fig. 3, and therefore only the differences between the two embodiments will be described. In the present embodiment, the housing 41 includes a bottom portion 412. The abutment surface 41a is located at the bottom 412. The airflow generator 42 is located between the keyboard 44 and the bottom 412.
因此，當使用鍵盤44時，使用者會對鍵盤44及鍵盤支撐件411施加壓力，進而對風流產生器42施加壓力，使風流產生器42之輪軸部421與設置於底部412之抵靠面41a之支撐凸塊43接觸。更甚者，支撐凸塊43能與輪軸部421之凹部421a之壁面接觸，使得支撐凸塊43與輪軸部421之接觸位置位於輪軸部421之旋轉中心。由於支撐凸塊43與輪軸部421間為點的接觸，且二者之接觸位置位於輪軸部421之旋轉中心，而能減少支撐凸塊43及輪軸部421之間的摩擦力及摩擦力矩，進而避免風流產生器42的轉速下降，以維持風流產生器42之風流產生功能。Therefore, when the keyboard 44 is used, the user applies pressure to the keyboard 44 and the keyboard support member 411, thereby applying pressure to the airflow generator 42, so that the axle portion 421 of the airflow generator 42 and the abutment surface 41a provided at the bottom portion 412. The support bumps 43 are in contact. Furthermore, the support projection 43 can be in contact with the wall surface of the recess 421a of the axle portion 421 such that the contact position of the support projection 43 with the axle portion 421 is located at the center of rotation of the axle portion 421. Since the contact between the support bump 43 and the axle portion 421 is point-contacted, and the contact position between the two supports is located at the center of rotation of the axle portion 421, the frictional force and the frictional moment between the support projection 43 and the axle portion 421 can be reduced. The rotation speed of the air flow generator 42 is prevented from dropping to maintain the air flow generation function of the air flow generator 42.
請參照第5圖，繪示依照本發明之另一實施例之電子裝置5之剖面圖。電子裝置5與第3圖所示之電子裝置5相似， 故在此僅就兩實施例之差異進行說明。於本實施例中，風流產生器52還包括一吸引件524，設置於輪軸部521之凹部521a內。於一實施態樣中，支撐凸塊53之材質為如磁鐵之磁性物質，吸引件524之材質為如鐵、鈷及鎳等之導磁性物質。於另一實施態樣中，吸引件524之材質為磁性物質，支撐凸塊53之材質為導磁性物質。於又一實施態樣中，支撐凸塊53及吸引件524為磁性相反之磁性物質，例如支撐凸塊53為N極而吸引件524為S極，或支撐凸塊53為S極而吸引件524為N極。Referring to FIG. 5, a cross-sectional view of an electronic device 5 in accordance with another embodiment of the present invention is shown. The electronic device 5 is similar to the electronic device 5 shown in FIG. Therefore, only the differences between the two embodiments will be described here. In the present embodiment, the airflow generator 52 further includes a attracting member 524 disposed in the recess 521a of the axle portion 521. In one embodiment, the material of the support bump 53 is a magnetic substance such as a magnet, and the material of the attracting member 524 is a magnetic conductive material such as iron, cobalt or nickel. In another embodiment, the material of the attracting member 524 is a magnetic substance, and the material of the supporting protrusion 53 is a magnetic conductive substance. In still another embodiment, the support bumps 53 and the attracting members 524 are magnetic materials having opposite magnetic properties. For example, the support bumps 53 are N poles and the attracting members 524 are S poles, or the support bumps 53 are S poles and the attracting members are 524 is the N pole.
因此，當使用鍵盤54時，使用者會對鍵盤54及殼體51之鍵盤支撐件511施加壓力，使設置於鍵盤支撐件511之抵靠面51a之支撐凸塊53與風流產生器52之輪軸部521接觸。更甚者，支撐凸塊53能藉由與輪軸部521之凹部521a內之吸引件524相互吸引，而使支撐凸塊53能被引導至輪軸部521之凹部521a內，即輪軸部521之旋轉中心。由於支撐凸塊53與吸引件524間為點的接觸，且二者之接觸位置位於輪軸部521之旋轉中心，而能減少支撐凸塊53及吸引件524之間的摩擦力及摩擦力矩，進而避免風流產生器52的轉速下降，以維持風流產生器52之風流產生功能。Therefore, when the keyboard 54 is used, the user applies pressure to the keyboard 54 and the keyboard support member 511 of the housing 51 so that the support projection 53 provided on the abutment surface 51a of the keyboard support member 511 and the axle of the airflow generator 52 are provided. The part 521 is in contact. Furthermore, the support projections 53 can be attracted to the recesses 521a of the axle portion 521 by the suction members 524 in the recesses 521a of the axle portion 521, that is, the rotation of the axle portion 521 center. Since the contact between the supporting protrusion 53 and the attracting member 524 is in point, and the contact position of the two is located at the center of rotation of the axle portion 521, the frictional force and the frictional torque between the supporting projection 53 and the attracting member 524 can be reduced, thereby further reducing the frictional force and the frictional moment between the supporting projection 53 and the attracting member 524. The rotation speed of the air flow generator 52 is prevented from dropping to maintain the air flow generating function of the air flow generator 52.
綜上所述，本發明之電子裝置，能夠在殼體受壓時，藉由支撐凸塊使殼體與風流產生器以點的方式接觸，而能避免大面積之殼體擠壓風流產生器。藉此，即使殼體受到外力壓迫，風流產生器所受到的摩擦力及摩擦力矩也能夠降至最低，以避免風 流產生器之流速下降，而能夠維持風流產生器之散熱效率。In summary, the electronic device of the present invention can contact the airflow generator in a point manner by supporting the bumps when the casing is pressed, thereby avoiding the large-area casing squeezing airflow generator. . Thereby, even if the casing is pressed by an external force, the frictional force and the friction torque received by the airflow generator can be minimized to avoid the wind. The flow rate of the flow generator is reduced, and the heat dissipation efficiency of the air flow generator can be maintained.
