五、新型說明： 【新型所屬之技術領域】 [0001] [0002] [0003] 本創作係關於一種包覆式轉轴之定位穩定結構，尤 指一種可強化相組合之套接件與轴接件間的定位性、穩 定性及改善其間之操作手感的轉轴結構。 【先前技術】- 在目前的時尚電子產品中，掀蓋式（或摺疊式）之 結構已被普遍而廣泛地應用，諸如可攜式電腦、電子秘 書、攜帶式影音播放裝置、行動電話·· ••等：其大 體上係由兩可相互摺合及掀啟之主體與其蓋體，在其間 之一選擇性邊緣處，裝設至少一樞軸結構；該樞軸結構 之良劣，直接影響上述產品之使用便利性與操作手感； 較重要者，係該等轉軸，除了需具備基本之反覆開合功 能外，在整個開合角度間，如何能達到隨遇定位、定位 穩定、長久多次使用仍能保持不鬆動，以及開輕關重之 良好手感等，均係成為優良轉軸之需求條件。 在現行之轉軸結構中，其中一類型為軸向串接磨擦 式，主要係在一軸件上串接複數軸向磨擦件，利用該等 磨擦件之相互壓合作用，以提供該軸件與串結在該軸件 上之一轉動件間的相對轉動磨擦阻力，藉此，即可而產 生所需的相互轉動隨遇停滯之效果，但此一結構尚無法 達到特殊角度之加強制動（鎖制）作用，而且在反覆使 用一段時間之後，由於各磨擦件間之逐漸磨損，將造成 上述緊迫壓合之作用產生鬆弛，不僅前述之隨遇停滯效 果曰漸消失，過度鬆弛亦將產生轉動操作之鬆動異音； 表單編號A0101 第3頁/共19頁 M430808 為此業界雖提出不少改善方案，其效果仍然有限；然而 ，該軸向磨擦轉軸之結構型態，並非本案所採用之技術 ，於此恕不再贅述。 [0004] 本創作主要係有關一種包覆式轉轴之結構設計其 與傳統套接式轉軸相關，亦即所謂之徑向磨擦式轉軸結 構；此一類型之轉軸，通常係由一套接件及與該套接件 軸向套接之轴接件所構成，該套接件之一端設有一套筒 或包覆部，而該軸接件則具有一可接受該套筒或包覆部 所套圍之軸柱，較早期者之該軸柱上’係開設有一軸向 剖溝，使其具有徑向彈性伸縮功能，以便於可強迫式彈 性套插入該套筒或包覆部之内部，使套接件與軸接件之 間，利用該軸柱在該套筒或包覆部内所產生之相互磨擦 扭矩，來達成前揭隨遇停滯之基本功能，但仍然無法提 供在特殊角度進一步設定加強制動之效果。 [0005] 因此，基於前述之需求，曾有先前之設計人，特別 提供了一種可以在轉轴件之特定轉動位置，使具有自動 強化制動之效果的結構設計’其係在一軸接件之轴枝表 面設有一配合平面，而且在一套接件之一部份，對應該 軸柱外徑設具一圓弧包覆部，以及一非對應該軸柱外禋 而漸縮之一縮圍部，該包覆部及縮圍部之包捲端緣間， 保留有一間隙，邊軸枉則被包覆結合在該包覆部與縮圍 部之間所形成之一軸插空間中；藉由軸柱在其間所受到 之迫緊度，形成前揭隨遇停滯之作用，並利用該縮圍部 之該包捲端緣，在某一特殊轉動角度可抵制該軸柱配合 平面之現象，產生前揭特殊轉動角度加強制動或自動鎖 表單编號A0101 第4頁/共19頁 [0006] 制之效果。 然而，隨之更有另一創作，係在套接件之一端設具 一中空套筒或包覆部，且在該套筒或包覆部之上，開設 一軸向溝槽，該套筒或包覆部之内壁更形成有一内配合 平面；此外，在相配合之軸接件的軸柱上，對應該内配 合平面，設有一外配合平面，使得在該套接件與軸接件 相套組合，並相對轉調至某一轉動角度時，該内、外配 合平面間，可產生一對應吻合之效果，藉此，即可產生 前述之知強制動作用；而J·，由於在該内、外配合平面 ，在非吻合狀態，彼此間會產生平涉頂推作用，因此， 會在較接近雙向的吻合之轉動行程内，產生自動推引轉 動至吻合之作用，使用於器物時，則會產生短距離自動 閉合或開啟至定位之效果，應用上更具多元特性。 [0007] 因此，對於上述轉軸結構之基本隨遇停滯、特殊角 度強化制動定位，以及特定角度短距離之自動推移閉合 或開啟等功能，目前已有較成熟之結構設計可供運用； 然而，本案創作人經過長時間的實際體驗，仍發現上揭 轉軸結構，仍存在有如下之缺點： [0008] 1. 套接件之包覆部或套筒部，受到軸接件之軸柱，在 使用中的不斷反覆頂推開合，日久仍會產生彈性疲 乏的鬆弛現象，而此現象在該内外配合平面相吻合 的狀態，常產生鬆弛晃動之不良現象。 2. 開啟與閉合之操作需求力，由於前揭加強制動及自 動推移定位結構之設計，均有施作力加強之現象， 無法達到開輕關重之優良操作手感。 表單编號A0101 第5頁/共19頁 M430808 3. 套接件與轴接件間之緊束力，若因為軸柱與套筒部 或包覆部間之長期磨耗而鬆弛，上述之隨遇停滯功 能將日益消失，仍有加以改善之必要性。 【新型内容】 [0009] 有鑑於上述之需求，本創作主要在於提供一種包覆 式轉軸之定位穩定結構，其包括有一套接件及一與之相 套合之軸接件；在該套接件與軸接件之相套合部位間， 設有可分別在不同轉動量（旋轉角度或位置）處，產生 吻合或不吻合之複數相配合面，利用該等相配合面之吻 合與不吻合數量的差異，得以設定各不同轉動量處之定 位力量的大小，藉此，即可輕易地在相對轉動件之間， 對特殊的掀合角度需求，提供與其他轉動量（角度）各 不相同之定位力量設定。 [0010] 藉由上述之定位力量設定結構，本創作可以在轉軸 之轉動起始點與轉動終點，分別設定不同數量的配合面 產生吻合與不吻合，以簡易達到所需之輕重操作手感（ 例如開輕關重之手感）及功能者。 [0011] 再者，上述之各配合面相吻合與不相吻合之對應狀 態，利用各配合面處於吻合之狀態時，得以產生定位力 量之加強，且於各處於不相吻合之配合面位置（包括包 覆部尾端之預設干涉部），則由於套接件與軸接件間存 在之干涉量，而產生相互推壓之彈性緊迫效果，此恰足 以提供前述自助推引至定位之功能，且得以進一步改善 使用日久，而在各轉動定位處產生鬆弛晃動之缺失者。 【實施方式】 表單編號A0101 第6頁/共19頁 [0012] 於是，為了進一步揭示本案之具體技術與功效，麦 配合適當可行實施例圖式，詳細說明如下；如圖所示者 [0013] 請參第1圖至第3圖所示者，本創作至少具有一套 接件1 0及與該套接件1 〇相組套合之一軸接件2 〇， 该套接件1〇至少具有一内部具有軸包空間111之包 覆。!5!·]·(或套筒部），該轴包空間111之内壁，大 體依一圓弧内徑形成捲包狀態之内壁，且在不同的角分 段區間，可芬別形成複數個與該圓弧内徑不相符之内配 &面112(可為平面或非平面），更可特別在該包覆 1 1之尾端處，可設置一與該圓弧内徑產生差異之干 涉部1 1 3 ; [0014] 該軸接件2 0至少具有一可插組於該包覆部1 1之 内的軸柱2 1 ’該軸柱2 1之徑身以不小於上述圓弧内 牷為較佳’且該軸柱2 1之軸面上，配合該套接件1 〇 之上内配合面1 1 2之型式，亦設有相同或不相同數量 之外配合面2 1 1，且該外配合面2 1 1在軸柱2 1上 之角分段區間，與該内配合面1 1 2在包覆部1 1之軸 包空間1 1 1中之角分段區間，可設為各不相同；如此 ’當該軸柱21插套於包覆部11之軸包空間111之 内部時，該等内配合面1 1 2與外配合面2 1 1之吻合 數量’即可以在套接件1 〇與軸接件2 0處於不同轉動 量時，產生各不相同之設定與變化，以調整其定位力量 ;例如，在套接件1 〇與軸接件2 0處於閉合狀態時（ 請參第3圖及第7圖），該等内配合面112可設定只 表單編號A0101 第7頁/共19頁 對單一外配合面2 1 1產生吻合，其他内、外配合面1 1 2、2 1 1則均存在轉動角度干涉量而不相吻合，因 此，該位置之定位力量主要係由該相吻合之内外配合面 所&供，其他存在轉動角度干涉量而不吻合之内、外配 合面間，則因包覆部及軸柱間之干涉推擠，產生彼此間 之内外彈性緊迫作用，適足以產生防鬆弛及防定位晃動 之現象。 [0015] 其次，當該套接件1 0與轉接件2 〇處於開啟狀態 時（請參第4及第9圖），該内配合面112 (或含干 涉部1 1 3)可設定為至少對兩個以上之外配合面2 1 1產生吻合，如此即可在該開啟轉動位置，產生加強之 疋位力量，其他未相吻合之内外配合面間，亦能產生前 述之内外彈性緊迫防鬆、防晃動作用；因此，由上述兩 不同狀態之比較，可以發現上述之套接件1 〇與軸接件 2 0之間，在閉合狀態時之定位力量，明顯因為内外配 合面之吻合數較少，而小於開啟狀態之定位力量，藉此 乃得以簡易產生開輕關重之效果；於是，本創作得以在 各不同轉動量處（請參第3 ' 4、7、8、9圖），依 需求設計以各不相同之内外配合面吻合數，以產生各不 同之定位力量；而且在各不同轉動定位處，更由於均存 在有數量不同之不相吻合内外配合面，使得該包覆部1 1與軸柱21之間，常態性可產生内外干涉緊迫壓合之 作用，恰足以消除在定位狀態，該包覆部1 1與軸柱2 1間，可能產生之鬆弛晃動現象，而能改善前揭傳統者 之缺失。 第8頁/共19頁 表單蝙號A0101 [0016] 再者，當該内外干涉緊迫壓合之作用力產生時，在 接近各内外配合面吻合點之附近，顯然又能產生短距離 之自動推引定位作用，特別在接近套接件1 0與軸接件 2 0轉動初始點及終點之處，更能產生自動推引閉合及 自動推引全開之作用，使用上更為便利。 [0017] 是以，經由本創作之結構設計，可以輕易改善前揭 各傳統轉轴之應用缺失，且特別得以簡易設定不同轉動 量位置產生不同定位力量及防鬆動之作用，以提供更多 —一先化及更高品質_之應用。. — - [0018] 再者，本案所前述者，乃僅為較佳實施例之說明， 因而舉凡依本創作之設計理念所進行之局部變更或修飾 ，而為熟習此項技藝之人所易於推知者，均應屬於本案 所得主張之專利權範疇，合先陳明。 【圖式簡單說明】 [0019] 第1圖係本創作一較佳實施例（包覆部具有二處内配合 面，抽柱有三處外配合面）之立體分解圖。 [0020] 第2圖係第1圖所示實施例之立體組合圖。 [0021] 第3圖係第2圖所示實施例之閉合狀態側視圖。 [0022] 第3A圖係第3圖之局部放大圖。 [0023] 第4圖係第2圖所示實施例之全開啟狀態側視圖。 [0024] 第4A圖係第4圖之局部放大圖。 [0025] 第5圖係本創作另一較佳實施例（包覆部具有三處内配 合面，軸柱有四處外配合面）之立體分解圖。 表單编號A0101 第9頁/共19頁 M430808 [0026] 第6圖係第5圖所示實施例之立體組合圖。 [0027] 第7圖係第6圖所示實施例之閉合狀態局部側視圖。 [0028] 第8圖係第6圖所示實施例之半開啟狀態的局部侧視圖 〇 [0029] 第9圖係第6圖所示實施例之全開啟狀態的局部側視圖 〇 【主要元件符號說明】 [0030] 10 · · ••套接件 [0031] 11 · · ••包覆部 [0032] 111 · • ••轴包空間 [0033] 112 · • · ·内配合面 [0034] 113 · •··干涉部 [0035] 20 · · ••軸接件 [0036] 21 · · .·轴柱 [0037] 211 · • · ·外配合面 表單編號A0101 第10頁/共19頁V. New Description: [New Technology Field] [0001] [0002] [0003] This paper is about a positioning and stabilizing structure of a coated rotating shaft, especially a socket and a shaft joint capable of strengthening the combination. The positioning between the parts, the stability and the shaft structure that improves the handling feel between them. [Prior Art] - In the current fashion electronics, the clamshell (or folding) structure has been widely used, such as portable computers, electronic secretaries, portable audio and video playback devices, mobile phones. •• etc.: It is generally composed of two bodies that can be folded and twisted together with their cover, at least one pivotal structure at one of the selective edges; the poorness of the pivot structure directly affects the above The ease of use and the feel of the operation of the product; the more important ones, in addition to the basic reversal opening and closing function, how to achieve the positioning, stable positioning and long-term use among the entire opening and closing angles. The ability to remain unsmooth, as well as the good feel of opening and closing the weight, is a demand condition for an excellent shaft. In the current shaft structure, one of the types is an axial series friction type, which mainly connects a plurality of axial friction members on a shaft member, and the mutual friction cooperation of the friction members is used to provide the shaft member and the string. The relative rotational frictional resistance between the rotating members of the shaft member, thereby achieving the desired mutual rotation and stagnation effect, but the structure cannot achieve the special angle of the reinforced braking (locking) ), and after repeated use for a period of time, due to the gradual wear between the friction members, the above-mentioned pressing action will cause slack, not only the aforementioned stagnation effect will gradually disappear, excessive relaxation will also produce a rotating operation. Loose noise; Form No. A0101 Page 3 of 19 M430808 Although many improvements have been proposed for the industry, the effect is still limited; however, the structural form of the axial friction shaft is not the technology used in this case. This will not be repeated here. [0004] This creation mainly relates to the structure design of a coated rotating shaft, which is related to the traditional socket type rotating shaft, which is also called a radial friction type rotating shaft structure; this type of rotating shaft is usually a set of connecting parts. And a shaft joint that is axially sleeved with the sleeve member, one end of the sleeve member is provided with a sleeve or a covering portion, and the shaft joint member has a sleeve or a covering portion The shaft column of the sleeve is formed by an axial groove on the shaft column of the earlier one, so that the radial elastic expansion function is provided, so that the forcible elastic sleeve is inserted into the sleeve or the inside of the covering portion. Between the socket and the shaft joint, the mutual frictional torque generated by the shaft column in the sleeve or the covering portion is used to achieve the basic function of the stagnation, but it is still unable to provide further setting at a special angle. Strengthen the effect of braking. [0005] Therefore, based on the foregoing needs, a prior designer has provided, in particular, a structural design capable of automatically reinforcing the brake at a specific rotational position of the shaft member, which is attached to the shaft of the shaft member. The surface of the branch is provided with a matching plane, and in one part of the set of parts, a circular arc covering portion is arranged corresponding to the outer diameter of the shaft column, and a shrinking portion is formed by the outer side of the shaft column a gap is left between the wrapping edge of the covering portion and the narrowing portion, and the side shaft is wrapped and integrated in an axial insertion space formed between the covering portion and the narrowing portion; The tension between the column and the stagnation of the column is formed, and the edge of the wrapping of the narrowing portion is utilized to resist the phenomenon of the matching plane of the shaft column at a certain rotation angle. Uncover special rotation angles to enhance the effect of braking or automatic lock form number A0101 Page 4 of 19 [0006]. However, there is another creation, which is provided with a hollow sleeve or a covering portion at one end of the socket, and an axial groove is formed on the sleeve or the covering portion. Or the inner wall of the covering portion is further formed with an inner matching plane; further, on the shaft post of the mating shaft connecting member, corresponding to the inner matching plane, an outer mating plane is provided, so that the sleeve member and the shaft joint portion are When the sleeve is combined and relatively transferred to a certain rotation angle, an effect of a corresponding anastomosis can be generated between the inner and outer mating planes, thereby generating the aforementioned forcible action; and J·, because The outer mating plane, in the non-anasthetic state, will produce a flattening pushing effect between each other. Therefore, in the rotation stroke closer to the two-way anastomosis, the automatic pushing and rotating to the anastomosis effect is generated, and when used in the object, It will produce the effect of automatically closing or opening to a short distance, which is more diverse in application. [0007] Therefore, for the basic stagnation of the above-mentioned rotating shaft structure, the special angle-enhanced braking positioning, and the automatic closing or opening of a specific angle and a short distance, a relatively mature structural design is available; however, the present case After a long period of actual experience, the creator still found that the shaft structure was revealed, and there are still the following shortcomings: [0008] 1. The cladding or sleeve portion of the socket is subjected to the shaft column of the shaft joint, and is in use. In the continuous reversal of the opening and closing, the elastic fatigue is still loosening for a long time, and this phenomenon often causes slack and sloshing in the state of the inner and outer matching planes. 2. The operation and demand of opening and closing operations, due to the design of the front-reinforced brake and the self-propelled positioning structure, all have the effect of strengthening the force, and can not achieve the excellent operation feel of light weight. Form No. A0101 Page 5 of 19 M430808 3. The tight force between the socket and the shaft joint is loosened due to the long-term wear between the shaft column and the sleeve portion or the cladding portion. The stagnation function will disappear and there is still a need to improve it. [New content] [0009] In view of the above needs, the present invention mainly provides a positioning and stabilizing structure of a coated rotating shaft, which comprises a set of connecting parts and a shaft connecting piece with the same; Between the fitting parts of the shaft and the shaft joint, there are a plurality of matching surfaces which can be matched or not matched at different rotation amounts (rotation angles or positions), and the matching and non-matching of the matching surfaces are used. The difference in the number is able to set the magnitude of the positioning force at each different amount of rotation, thereby making it possible to provide different rotation angles (angles) between the relative rotating parts and the special turning angle requirements. Positioning power setting. [0010] With the above-mentioned positioning force setting structure, the creation can set a different number of mating surfaces to achieve an anastomosis and a mismatch between the rotation starting point and the rotation end point of the rotating shaft, so as to easily achieve the required light and heavy operation feeling (for example) The light touches the feeling) and the function. [0011] Furthermore, the matching surfaces of the above-mentioned mating surfaces are in a state of being inconsistent with each other, and when the mating surfaces are in an anastomosis state, the positioning force is strengthened, and the mating surface positions are not consistent at all places (including The predetermined interference portion at the end of the covering portion, due to the interference between the socket and the shaft member, produces an elastic pressing effect of pushing against each other, which is sufficient to provide the self-service push-to-position function. Moreover, it is possible to further improve the use time, and the missing of the slack is generated at each rotational positioning. [Embodiment] Form No. A0101 Page 6 of 19 [0012] Therefore, in order to further disclose the specific technology and efficacy of the present invention, the following is a detailed description of the possible implementation of the embodiment of the present invention; as shown in the figure [0013] Referring to Figures 1 to 3, the present invention has at least one set of connectors 10 and one of the shaft members 2 套 of the sleeve member 1 〇, the socket member 〇 has at least An interior has a cladding of the shaft package space 111. !5!··· (or the sleeve portion), the inner wall of the shaft package space 111 generally forms an inner wall in a wrapped state according to an inner diameter of a circular arc, and can form a plurality of different sections in different angular sections. The internal matching & surface 112 (which may be planar or non-planar) does not correspond to the inner diameter of the circular arc, and particularly at the end of the cladding 1 1 , a difference may be set between the inner diameter of the circular arc and the inner diameter of the circular arc. The interference portion 1 1 3 ; [0014] the shaft connector 20 has at least one shaft column 2 1 ' can be inserted into the cladding portion 1 1 'the shaft of the shaft column 2 1 is not less than the above-mentioned arc The inner raft is preferably 'and the axial surface of the shaft column 2 1 is matched with the inner mating surface 1 1 2 of the socket 1 ,, and the same or different number of outer mating surfaces 2 1 1 are also provided. And the angular portion of the outer mating surface 2 1 1 on the shaft column 2 1 and the inner mating surface 1 1 2 in the angular section of the shaft packing space 1 1 1 of the covering portion 1 1 Therefore, when the shaft post 21 is inserted into the inside of the shaft package space 111 of the covering portion 11, the number of the inner mating surfaces 1 1 2 and the outer mating surface 2 1 1 can be In the socket 1 〇 and the shaft connector 2 0 When the rotation amount is different, different settings and changes are generated to adjust the positioning force; for example, when the socket 1 〇 and the shaft connector 20 are closed (refer to Fig. 3 and Fig. 7) The inner mating surfaces 112 can be set to form only the form number A0101, page 7 / 19 pages, and the other outer mating surfaces 2 1 1 are matched, and the other inner and outer mating surfaces 1 1 2, 2 1 1 have rotational angle interference. The quantity does not coincide with each other. Therefore, the positioning force of the position is mainly due to the matching of the inner and outer mating surfaces of the phase, and the other inner and outer mating surfaces which do not match the rotational angle interference amount, because of the covering portion And the interference between the shaft columns pushes, and the internal and external elastic pressing action is generated, which is suitable for the phenomenon of anti-relaxation and anti-positioning sway. [0015] Next, when the socket 10 and the adapter 2 are in an open state (refer to FIGS. 4 and 9), the inner mating surface 112 (or the interference-containing portion 1 1 3) can be set to At least two or more outer mating surfaces 2 1 1 are matched, so that the reinforced clamping force can be generated at the opening rotational position, and the other inner and outer mating surfaces which are not matched can also generate the aforementioned internal and external elastic tight prevention. For the loose and anti-sway action; therefore, by comparing the above two different states, it can be found that the positioning force between the above-mentioned socket 1 〇 and the shaft joint 20 in the closed state is obviously due to the number of internal and external mating surfaces. Less, but less than the positioning power of the open state, thereby making it easy to produce the effect of opening and closing the weight; thus, the creation can be at different rotations (see Figure 3 '4, 7, 8, 9) According to the requirements, the matching numbers of the inner and outer mating surfaces are designed to produce different positioning forces; and at different rotational positioning positions, the coatings are made up of different numbers of different inner and outer mating surfaces. Between the portion 1 1 and the shaft column 21 Normality may be generated both inside and outside the interference effect of the pressing nip, just sufficient to eliminate the positioning state, two one-axis column 11 and the cladding portion, the slack of a sloshing phenomenon may occur, and deletions can be improved by the above-mentioned technical tradition. Page 8 of 19 Form No. A0101 [0016] Furthermore, when the force of the internal and external interference pressing compression is generated, it is apparent that an automatic push of a short distance can be generated in the vicinity of the matching points of the inner and outer mating surfaces. The positioning function, especially in the vicinity of the initial point and the end point of the rotation of the socket 10 and the shaft connector 20, can more automatically generate the function of automatic push-closing and automatic pushing, which is more convenient to use. [0017] Therefore, through the structural design of the creation, the application of the conventional rotating shaft can be easily improved, and the positioning force of different rotation positions can be easily set to generate different positioning forces and anti-looseness to provide more. A pre-emptive and higher quality application. [0018] Furthermore, the foregoing is merely illustrative of the preferred embodiments, and thus is susceptible to modification or modification by the design concept of the present invention, and is readily available to those skilled in the art. The inferred persons should belong to the patent right scope claimed in this case.
