200804095 九、發明說明： 【發明所屬之技術頜诚】 本案係關於/禮支撐機構’尤指一種應用於具有可掀 式上本體之電子裝置之支撐機構。 【先前技術】 隨著科技曰新月異’目前的電子裝置多朝向一機多功 能的技術發展，以市面上常見的事務機為例，由於可同時 提供傳真、影印、掃描以及列印等功能，不但具有多項文 書處理能力，所占的使用空間亦從四個位置減少為一個位 置。此外，組裝步驟比起過去簡化很多，而且僅僅需要單 一的網路線、電話線以及電源線就可搭配電腦來使用。因 此’當然會成為目前消費者購買同類性質產品的第一考量。 多功能事務機一般包含有自動饋紙裝置（ADF)以及紅 外線影像輪入裝置（IR Image Input Device)，當多功能事務 ，的内部引擎需要維修保養的時候，通常必須將自動饋紙 衣置以及;紅外線影像輸入裝置翻開。習知的技術中，鉸鏈 • ^連桿枚構(Linkage Mechanism)係裝設於紅外線影 像輸入裝置與L力能事務機連結的位置處。然而，由於自 旦貝因lb置以及紅外線影像輪入裝置皆具有相當程度的重 傳统絞鏈或連動機構往往不能夠平穩的撐住自 動饋紙裝置以及έ & 、 夂、^外線影像輪入裝置，使得自動饋紙裝置 以及紅外線影像^^ ^ 篆輸入I置常常不注意的就壓下來，甚至危 及維護人貝的安全。 請參閱第—R ^ /Ιλ ^ 圖’其係為習知多功能事務機之支撐裝置 9 200804095 之示意圖。如第一圖所示，其中多功能事務機之上本體101 與下本體102之間所設有之支撐裝置包含鉸鏈元件11、彈 簧12、上蓋板13以及下蓋板14,其中彈簣12係套環於鉸 鏈元件11之外，而鉸鏈元件11之一端固定於上蓋板13， 另一端固定於下蓋板14。當多功能事務機之上本體1〇1往 上開啟或向下關閉的時候，支撐裝置之鉸鏈元件11與彈簧 12係同部延伸或縮短長度，以順著上本體101開啟或關閉 的角度，利用鉸鏈元件11與彈簣12具有彈性的特性改變 其長度，同時產生抗拒扭力以支撐多功能事務機之上本體 101的重量。 由於，為了配合多功能事務機的大小，在設計上必須 盡量將支撐裝置所佔的體積與面積縮小，如此亦影響絞鏈 元件11以及彈簧12的長度及大小，因而使得產生之抗拒 扭力的大小受到限制而無法滿足實際的需求。一旦上本體 101的重量到達某個極限值，尤其是自動饋紙裝置（ADF) 以及紅外線影像輸入裝置（IR Image Input Device)如此重的 設備，如此設計的支撐裝置實在已經無法負荷其重量，而 經常忽然『蹦』一聲的就會使得上本體101整個掉下來， 不但對内部的電子元件產生強大的撞擊力量，對於維護人 員來說，安全上亦有相當程度的危險。 因此，為了確保電子裝置之上本體於開啟與關閉過程 中的平穩性，實有必要研發出一種解決上述諸多缺點並適 用各種不同重量之支撐機構，以符合當今之實際需求。 【發明内容】 200804095 本案之主要目的在於提供一種支撐機構，其係可平穩 的支撐電子裝置之上本體，以解決習知電子裝置之上本體 於開啟或關閉的過程中，因受支撐之扭力不足或上本體重 量過重的因素，而瞬間往下掉落的缺失。 為達上述目的，本案係提供一種支撐機構，用以支撐 電子裝置之上本體，其中電子裝置更包含下本體，且上本 體係可相對下本體作軸轉運動。本案之支撐機構包含：基 座、板件、傳動軸、第一扭力產生裝置以及第二扭力產生 裝置。其中基座固定於電子裝置之下本體，而板件固定於 電子裝置之上本體，傳動轴設於基座上並結合板件，以使 板件得以相對基座轴轉，第一扭力產生裝置係套設於傳動 轴，且於板件相對基座軸轉時產生第一扭力，第二扭力產

一彈奮套設於傳動轴且於板件相對基座轴轉時產生第一扭 力，以及第二彈簧套設於傳動軸且設於第一扭力產生裝置 之一侧，其中第二扭力產生裝置相對於傳動軸之環繞方向 與第一扭力產生裝置相對於傳動軸之環繞方向相反，俾於 11 200804095 板件相對基座軸轉時使第一扭力產生裝置與第二扭力產生 裝置產生方向相反之力矩。俾於板件相對基座軸轉時，使 支撐機構得以支撐電子裝置之上本體的重量。 根據本案上述之構想，其中當板件相對基座軸轉時， 傳動軸係隨板件軸轉。 根據本案上述之構想，其中更包含隔板，且設於第一 扭力產生裝置與第二扭力產生裝置之間，以供第一扭力產 生裝置以及第二扭力產生裝置之其中一端可固定於隔板。 根據本案上述之構想，其中第一扭力產生裝置與第二 扭力產生裝置係可為摩擦片。 根據本案上述之構想，其中更可包含複數個第一扭力 產生裝置與第二扭力產生裝置。 根據本案上述之構想，其中更包含齒輪組，其係設於 每第一扭力產生裝置與第二扭力產生裝置之組合之間。 根據本案上述之構想，其中該齒輪組更包含第一齒輪 與第二齒輪。 根據本案上述之構想，其中電子裝置之上本體係為自 動饋紙裝置（ADF)、紅外線影像輸入裝置（IR Image Input Device)或防塵蓋之其中之一。 根據本案上述之構想，其中電子裝置之上本體係為自 動饋紙裝置（ADF)、紅外線影像輸入裝置（IR Image Input Device)以及防塵蓋之組合。 【實施方式】 本案係關於一種支撐機構，其係支撐電子裝置上本體 12 200804095 的重量，使上本體於開啟與關閉的過程中，不致瞬間掉落， 以保護上本體内的電子元件。本案之支撐機構係可廣泛地 應用於例如傳真機、影印機、掃描裝置或多功能事務機等 領域相同或類似的電子裝置。 請參閱第二圖（a)以及第二圖（b)，其係分別為本案之支 撐機構於關閉與開啟之狀態示意圖。同時參閱第三圖（a)以 及第三圖（b)，其係為本案之支撐機構於關閉與開啟之第一 扭力產生裝置與第二扭力產生裝置之作動關係示意圖。如 圖所示，本案之支撐機構2包含基座21、板件22、傳動軸 23、第一扭力產生裝置24以及第二扭力產生裝置25。其 中，基座21固定於電子裝置之下本體（未圖示），板件22 固定於電子裝置之上本體（未圖示），傳動轴23設於基座21 上並於兩端結合板件22，使得板件22可相對基座21進行 轴轉，第一扭力產生裝置24係套設於傳動軸23上，其係 可於板件22相對基座21進行軸轉時產生第一扭力，而第 二扭力產生裝置25亦套設於傳動軸上，且可放置於第一扭 力產生裝置24之任何一侧邊，第二扭力產生裝置25係可 於板件22相對基座21進行軸轉時產生第二扭力，其中所 產生之第一扭力與第二扭力之方向相反，如此一來，當電 子裝置之上本體相對下本體進行轉動時，方向相反的第一 扭力與第二扭力便得以分解電子裝置之上本體於軸轉時， 因本身重量所產生的巨大扭力，得以平穩的支撐住電子裝 置之上本體，而不致使電子裝置之上本體於開啟或關閉的 過程中，因重量無法受到完整支撐而掉落下來。 13 200804095 於本案的技術中，第一扭力產生裝置24與第二扭力產 生裝置25係可採用各式各樣的材質及元件。以本實施例而 言，第一扭力產生裝置24與第二扭力產生裝置25係可為 彈簧，且第一扭力產生裝置24與第二扭力產生裝置25之 間還設有隔板26，以使得第一扭力產生裝置24與第二扭 力產生裝置25被分隔開來而不會互相干擾，利用第二扭力 產生裝置25套設於傳動轴23之環繞方向與第一扭力產生 裝置24套設於傳動軸23之環繞方向相反的原理，當板件 22相對基座21軸轉時，如果第一扭力使得第一扭力產生 裝置24(彈簧）之内徑縮小的時候，與第一扭力相反的第二 扭力便會加大第二扭力產生裝置25(彈簧）之内徑，相反 的，當第一扭力使得第一扭力產生裝置24(彈簧）之内徑加 大的時候，與第一扭力相反的第二扭力便會縮小第二扭力 產生裝置25(彈簧）之内徑。不難想像的，如此的配合設計， 係可使得第一扭力與第二扭力將電子裝置之上本體因開啟 或關閉產生的巨大扭力轉換為較小的扭力，如此，不論電 子裝置之上本體有多重，或是開啟關閉的角度有多大或多 小，本案之支撐機構2都可以平穩的支撐住電子裝置之上 本體。 請參閱第四圖，其係為本案之支撐機構之第二較佳實 施例之示意圖。如圖所示，本案之支撐機構3之第一扭力 產生裝置34與第二扭力產生裝置35除了如第二圖所示的 彈簧以外，還可為摩擦片。其中第一扭力產生裝置34與第 二扭力產生裝置35係可互相交錯層疊，只要第一扭力產生 14 200804095 裝置34與第二扭力產生裝置35之其中之一固定在傳動軸 33上，當電子裝置之上本體相對下本體進行轉動時，固定 在傳動轴33上的扭力產生裝置（第一扭力產生裝置34與第 二扭力產生裝置35之其中之一）就會連同固定在上本體之 板件32 —起轉動，此時，藉由摩擦片的摩擦力作用，第一 扭力產生裝置34與第二扭力產生裝置35會產生方向相反 的第一扭力與第二扭力，如此，相同的道理，本實施例的 實施方式一樣可達到平穩支撐電子裝置之上本體的目的。 當然，本案之支撐機構之第一扭力產生裝置與第二扭 力產生裝置的數量並無限制，且包含的元件也可視情況需 要而增加。請參閱第五圖，其係為本案之支撐機構之第三 較佳實施例之示意圖。如圖所示，本實施例係利用兩組的 第一扭力產生裝置44與第二扭力產生裝置45裝設於傳動 轴43的兩邊，再於兩組的第一扭力產生裝置44與第二扭 力產生裝置45之中間處裝設用來轉換扭力的齒輪組46， 這個齒輪組46更包含了第一齒輪461與第二齒輪462,當 電子裝置之上本體翻動而使得傳動轴43轉動的時候，第一 齒輪461與第二齒輪462之間就會形成連帶運動，同時藉 由第一扭力產生裝置44與第二扭力產生裝置45產生方向 相反的第一扭力與第二扭力，上本體關閉或開啟時，重量 負載所產生的巨大扭力便可轉換成更小的扭力，使得支撐 機構4所能承受的扭力值範圍增加。不難想像的，藉由如 此的設計，不論電子裝置之上本體關閉或開啟的角度有多 大多小，或是上本體的重量是多少，本實施例都可提供足 15 200804095 夠的扭力來支撐住上本體，避免電子裝置之上本體無法受 到平穩支撐而落下的危險。 以上所舉的各個實施例中，第一扭力產生裝置以及第 二扭力產生裝置的實施樣態皆可互相搭配，而且實際上使 用的物件並不受限於本案所說明之實施例，只要是第一扭 力產生裝置與第二扭力產生裝置可以產生方向相反之第一 扭力及第二扭力即可。此外，第一扭力產生裝置與第二扭 力產生裝置之間係可加設有隔板，其不但可以將第一扭力 產生裝置與第二扭力產生裝置分隔開來以避免互相干擾， 同時，又可提供第一扭力產生裝置或第二扭力產生裝置固 定的支點，以使得第一扭力產生裝置與第二扭力產生裝置 可選擇性的將其一端固定於隔板上。此外，雖然沒有以圖 式的方式表現出來，但是不難想像的，本案所揭露的技術 係可廣泛的應用於可掀式的電子裝置，而且以多功能事務 機為例，本案所稱之電子裝置之上本體就可以是常見的自 動饋紙裝置（ADF)、紅外線影像輸入裝置（IR Image Input Device)或防塵蓋等等，亦或是自動饋紙裝置（ADF)、紅外 線影像輸入裝置（IR Image Input Device)以及防塵蓋之組 合。 綜上所述，本案之支撐機構係利用兩個以上的扭力產 生裝置各自提供方向相反的扭力，以使得電子裝置之上本 體於關閉或開啟的過程中，不管重量有多重，開啟或關閉 的角度為多少，都可以透過本案所提供之支撐機構，來使 得電子裝置之上本體可以很平穩的受到支撐，以避免電子 16 200804095 裝置之上本體瞬間摔落下來，達到增加穩定性及安全性的 目的。 是以，本發明確已符合發明專利之要件，爰依法提出 專利申請。惟，以上所述僅為本發明之較佳實施例，舉凡 熟悉本案技藝之人士援依本發明之創作精神所作之等效修 飾或變化，皆應涵蓋在本案所載之申請專利範圍内。200804095 IX. INSTRUCTIONS: [Technology of the invention belongs to the jaw] This case relates to a support mechanism, especially a support mechanism applied to an electronic device having a movable upper body. [Prior Art] With the rapid development of technology, the current electronic devices are more oriented toward the development of a multi-functional technology. Take the common business machines on the market as an example, because they can provide functions such as fax, photocopying, scanning, and printing. Not only does it have multiple document processing capabilities, but the space used is also reduced from four locations to one location. In addition, the assembly steps are much simpler than in the past, and only a single network route, telephone line, and power cord are required to be used with a computer. Therefore, it will certainly become the first consideration for consumers to purchase products of the same nature. The MFP usually includes an automatic paper feeding device (ADF) and an infrared image input device (IR Image Input Device). When the internal engine of the multi-function business needs maintenance, it is usually necessary to set the automatic paper feeding device. The infrared image input device is turned over. In the conventional technique, the hinge link mechanism is installed at a position where the infrared image input device and the L-energy machine are connected. However, since the self-dubening lb and the infrared image wheeling device have a considerable degree of heavy traditional hinges or linkages, it is often unable to smoothly support the automatic paper feeding device and the έ & 夂, ^ external line image wheeling The device allows the automatic paper feeding device and the infrared image ^^^ 篆 input I to be pressed down often without paying attention, even jeopardizing the safety of the maintenance person. Please refer to the -R ^ /Ιλ ^ diagram as a schematic diagram of the support device 9 200804095 of the conventional multifunction machine. As shown in the first figure, the supporting device provided between the upper body 101 and the lower body 102 of the MFP includes a hinge member 11, a spring 12, an upper cover 13 and a lower cover 14, wherein the magazine 12 The collar is outside the hinge member 11, and one end of the hinge member 11 is fixed to the upper cover 13 and the other end is fixed to the lower cover 14. When the main body 1〇1 is opened upward or closed downward, the hinge element 11 of the supporting device and the spring 12 are extended or shortened in the same length to follow the opening or closing angle of the upper body 101. The length of the hinge member 11 and the magazine 12 are changed by the elastic property, and the torsion resistance is generated to support the weight of the body 101 above the MFP. In order to match the size of the MFP, it is necessary to reduce the volume and area occupied by the supporting device as much as possible, which also affects the length and size of the hinge member 11 and the spring 12, thereby causing the resistance to the torsion. Restricted to meet actual needs. Once the weight of the upper body 101 reaches a certain limit, especially for an equipment such as an automatic paper feeder (ADF) and an infrared image input device (IR Image Input Device), the support device thus designed is unable to load its weight, and Frequently, the sudden slamming of the upper body 101 will cause the entire upper body 101 to fall down, not only has a strong impact force on the internal electronic components, but also a considerable degree of danger to the maintenance personnel. Therefore, in order to ensure the smoothness of the upper body of the electronic device during the opening and closing process, it is necessary to develop a supporting mechanism that solves the above various disadvantages and applies various weights to meet the actual needs of today.

[Embodiment] The present invention relates to a supporting mechanism for supporting the weight of the body 12 200804095 on the electronic device, so that the upper body does not fall off during the opening and closing process to protect the electronic components in the upper body. The supporting mechanism of the present invention can be widely applied to the same or similar electronic devices in fields such as a facsimile machine, a photocopier, a scanning device, or a multifunction machine. Please refer to the second figure (a) and the second figure (b), which are schematic diagrams of the state in which the supporting mechanism of the present case is closed and opened. Referring to the third figure (a) and the third figure (b), it is a schematic diagram of the actuation relationship between the first torque generating device and the second torque generating device which are closed and opened by the supporting mechanism of the present invention. As shown, the support mechanism 2 of the present invention includes a base 21, a plate member 22, a transmission shaft 23, a first torsion generating device 24, and a second torsion generating device 25. The base 21 is fixed to the lower body (not shown) of the electronic device, and the plate 22 is fixed to the upper body (not shown) of the electronic device. The drive shaft 23 is disposed on the base 21 and is combined with the plate at both ends. 22, the plate member 22 is pivotable relative to the base 21, and the first torsion generating device 24 is sleeved on the transmission shaft 23, which is capable of generating a first torque when the plate member 22 is pivoted relative to the base 21. The second torsion generating device 25 is also sleeved on the transmission shaft and can be placed on either side of the first torsion generating device 24, and the second torsion generating device 25 can be pivoted relative to the base 21 of the plate member 22. The second torsion force is generated, wherein the first torsion force is opposite to the direction of the second torsion force, so that when the upper body of the electronic device rotates relative to the lower body, the first torsion force and the second torsion force are opposite directions When the body above the electronic device is disassembled, the large torque generated by the weight of the electronic device can smoothly support the upper body of the electronic device without causing the upper body of the electronic device to be opened or closed, due to the weight Finished Falling down with the support. 13 200804095 In the technique of the present invention, the first torsion generating device 24 and the second torsion generating device 25 can be made of various materials and components. In this embodiment, the first torsion generating device 24 and the second torsion generating device 25 may be springs, and a partition 26 is further disposed between the first torsion generating device 24 and the second torsion generating device 25 to enable The first torsion generating device 24 and the second torsion generating device 25 are separated from each other without interference with each other, and the second torsion generating device 25 is sleeved in the circumferential direction of the transmission shaft 23 and the first torsion generating device 24 is sleeved on the The principle that the driving shaft 23 is opposite in direction, when the plate member 22 is pivoted relative to the base 21, if the first torsion force causes the inner diameter of the first torsion generating device 24 (spring) to be reduced, the first torque is opposite to the first torsion The second torsion increases the inner diameter of the second torsion generating device 25 (spring). Conversely, when the first torsion causes the inner diameter of the first torsion generating device 24 (spring) to increase, the first torsion is opposite. The second torsion reduces the inner diameter of the second torsion generating device 25 (spring). It is not difficult to imagine that such a matching design can cause the first torsion and the second torsion to convert the large torque generated by the opening or closing of the upper body of the electronic device into a smaller torque, so that the upper body of the electronic device has The multiple or the angle of opening and closing is large or small.

As shown in the figure, the first torsion generating device 34 and the second torsion generating device 35 of the supporting mechanism 3 of the present invention may be a friction plate in addition to the spring as shown in the second figure. The first torsion generating device 34 and the second torsion generating device 35 are mutually staggered, as long as the first torsion generating 14 200804095 one of the device 34 and the second torsion generating device 35 is fixed on the transmission shaft 33, when the electronic device When the upper body rotates relative to the lower body, the torque generating device (one of the first torque generating device 34 and the second torque generating device 35) fixed to the transmission shaft 33 is coupled with the plate member 32 fixed to the upper body. Rotating, at this time, by the frictional force of the friction plate, the first torsion generating device 34 and the second torsion generating device 35 generate the first torsion and the second torsion in opposite directions, and thus, the same principle, the present embodiment The embodiment of the example can achieve the purpose of smoothly supporting the upper body of the electronic device. Of course, the number of the first torsion generating device and the second torsion generating device of the supporting mechanism of the present invention is not limited, and the components included may also be increased as needed.

As shown in the figure, the first torsion generating device 44 and the second torsion generating device 45 of the two sets are mounted on both sides of the transmission shaft 43 and then the first torsion generating device 44 and the second torsion of the two groups. A gear set 46 for converting a torque is disposed in the middle of the generating device 45. The gear set 46 further includes a first gear 461 and a second gear 462. When the upper body of the electronic device is flipped to rotate the drive shaft 43, The first gear 461 and the second gear 462 form a joint motion, and the first torque generating device 44 and the second torque generating device 45 generate the first torque and the second torque in opposite directions, and the upper body is closed or opened. At this time, the large torque generated by the weight load can be converted into a smaller torque, so that the range of torque values that the support mechanism 4 can withstand increases. It is not difficult to imagine that with such a design, no matter how much the angle of the upper body of the electronic device is closed or opened, or the weight of the upper body, the embodiment can provide sufficient torque to support the foot 15 200804095.

In addition, a partition may be added between the first torsion generating device and the second torsion generating device, which not only separates the first torsion generating device from the second torsion generating device to avoid mutual interference, and at the same time, A fulcrum fixed to the first torsion generating device or the second torsion generating device may be provided such that the first torsion generating device and the second torsion generating device selectively fix one end thereof to the spacer. In addition, although it is not expressed in the form of a schema, it is not difficult to imagine that the technology disclosed in this case can be widely applied to portable electronic devices, and the multifunction transaction machine is taken as an example. The upper body of the device can be a common automatic paper feeding device (ADF), an infrared image input device (IR Image Input Device) or a dust cover, etc., or an automatic paper feeding device (ADF) or an infrared image input device (IR). Image Input Device) and a combination of dust caps.
