Description
本發明是有關於一種光學裝置及其鏡頭模組，且特別是有關於一種投影裝置及其鏡頭模組。The present invention relates to an optical device and a lens module thereof, and more particularly to a projection device and a lens module thereof.
投影裝置為一種用以隨時隨地可產生畫面的顯示裝置。投影裝置的成像原理是將光源所產生的照明光束藉由光閥轉換成影像光束，再將影像光束通過鏡頭投射到螢幕或牆面上以形成影像。隨著投影技術的進步及製造成本的降低，投影裝置的使用已從商業用途逐漸拓展至家庭用途。近來，各類電子產品皆朝向高速、高效能、且輕薄短小的趨勢發展，如此可具有可隨身攜帶且無使用場地限制的優點。The projection device is a display device for generating a picture anytime and anywhere. The imaging principle of the projection device is to convert the illumination beam generated by the light source into an image beam by a light valve, and then project the image beam through the lens onto the screen or the wall to form an image. With the advancement of projection technology and the reduction of manufacturing costs, the use of projection devices has gradually expanded from commercial use to home use. Recently, various types of electronic products have been developed toward high speed, high efficiency, and light and thin, so that they can be carried around without restrictions of use.
一般來說，可將投影裝置的鏡頭模組滑設於光機座，以利使用者調整其焦距。詳細而言，一種將鏡頭模組滑設於光機座的方式為，配置兩貫孔分別位於鏡頭模組的兩側，且配置兩導桿固定於光機座並分別位於鏡頭模組兩側，以使鏡頭模組藉由所述兩貫孔滑設於所述兩導桿。在此種配置方式之下，由於鏡頭模組的兩側皆需具有用以形成所述貫孔的凸塊，因此較為占據投影裝置的配置空間，增加其整體體積。此外，當鏡頭模組沿兩導桿滑動時，會因些微的組裝及製造公差而產生干涉性的力矩，使得鏡頭模組的調焦較為不順。Generally, the lens module of the projection device can be slid to the optical base for the user to adjust the focal length. In detail, a method for sliding the lens module to the optical base is such that two through holes are respectively disposed on two sides of the lens module, and two guiding rods are disposed on the optical base and are respectively located on both sides of the lens module. So that the lens module is slidably disposed on the two guiding rods by the two through holes. In this configuration, since both sides of the lens module need to have the bumps for forming the through holes, the arrangement space of the projection device is occupied, and the overall volume is increased. In addition, when the lens module slides along the two guide rods, interfering moments are generated due to slight assembly and manufacturing tolerances, which makes the focus adjustment of the lens module more unsatisfactory.
美國專利編號US20080024879A1揭露一種鏡頭模組，其鏡頭藉由導桿組進行滑設。美國專利編號US7199944揭露一種光學鏡組驅動裝置，藉由導桿對光學鏡組進行驅動。中華民國專利編號TWI248548揭露一種投影機鏡頭調整機構，藉由驅動輪及固定桿對鏡頭進行調整。然而，上述專利中皆採用複雜的機構設計，這些設計容易在製造時產生不可預期的製造公差，亦不利於投影裝置採微型化設計。US Patent No. US20080024879A1 discloses a lens module in which a lens is slidably disposed by a guide group. U.S. Patent No. 7,1999,044 discloses an optical lens assembly that drives an optical lens assembly with a guide bar. The Republic of China patent number TWI248548 discloses a projector lens adjustment mechanism that adjusts the lens by means of a drive wheel and a fixed rod. However, the above patents all employ complex mechanism designs that are prone to unpredictable manufacturing tolerances during manufacturing and are not conducive to miniaturization of the projection device.
本發明提出一種投影裝置，其具有較小的製造公差，且其鏡頭模組的調焦較為順暢。The invention provides a projection device with small manufacturing tolerances and a smooth focusing of the lens module.
本發明提出一種鏡頭模組，其具有較小的製造公差。The present invention provides a lens module that has less manufacturing tolerances.
本發明提出一種鏡頭模組，其可具有較小的體積，因而有助於投影裝置採微型化設計。The present invention provides a lens module that can have a small volume, thereby facilitating the miniaturization of the projection device.

Therefore, the directional terminology used is for the purpose of illustration and not limitation.
圖1為本發明一實施例之投影裝置的立體圖。圖2為圖1之鏡頭模組、第一導桿與第二導桿的立體圖。請參考圖1及圖2，本實施例的投影裝置100包括光機座110及鏡頭模組120。光機座110具有第一導桿112及第二導桿114，且第一導桿112實質上平行於第二導桿114。鏡頭模組120包括主體122、至少一第一凸塊124(繪示兩個為例)及第二凸塊126。主體122具有側面122a。第一凸塊124形成於主體122的側面122a且具有第一貫孔124a，並藉由第一貫孔124a滑設於第一導桿112。第二凸塊126形成於主體122的側面122a且具有第二貫孔126a，並藉由第二貫孔126a滑設於第二導桿114。藉此，鏡頭模組120可沿第一導桿112及第二導桿114相對光機座110移動，以進行調焦。1 is a perspective view of a projection apparatus according to an embodiment of the present invention. 2 is a perspective view of the lens module, the first guide rod and the second guide rod of FIG. 1. Referring to FIG. 1 and FIG. 2 , the projection apparatus 100 of the embodiment includes a light base 110 and a lens module 120 . The optical base 110 has a first guiding rod 112 and a second guiding rod 114, and the first guiding rod 112 is substantially parallel to the second guiding rod 114. The lens module 120 includes a main body 122 , at least one first bump 124 (two are shown as an example), and a second bump 126 . The body 122 has a side surface 122a. The first protrusion 124 is formed on the side surface 122a of the main body 122 and has a first through hole 124a, and is slidably disposed on the first guiding rod 112 by the first through hole 124a. The second protrusion 126 is formed on the side surface 122a of the main body 122 and has a second through hole 126a, and is slidably disposed on the second guiding rod 114 by the second through hole 126a. Thereby, the lens module 120 can be moved along the first guiding rod 112 and the second guiding rod 114 relative to the optical base 110 for focusing.
在上述配置方式之下，由於具有第一貫孔124a的第一凸塊124及具有第二貫孔126a的第二凸塊126位於主體122的同一側面122a，且第一導桿112與第二導桿114亦相應地位於主體122的同一側面122a，因此鏡頭模組120僅單側設有凸塊而在配置上較為節省空間，以使投影裝置100可具有較小的體積。此外，由於第一導桿112與第二導桿114位於主體122的同一側面122a而相距較近，因此在模具製造上可較準確地對位以降低製造公差。另外，由於相距較近的第一導桿112與第二導桿114之間構成較短的力臂，因此當鏡頭模組120沿第一導桿112與第二導桿114滑動時，可降低因組裝及製造公差而產生之力矩，以使鏡頭模組120的調焦較為順暢。In the above configuration, the first bump 124 having the first through hole 124a and the second bump 126 having the second through hole 126a are located on the same side surface 122a of the main body 122, and the first guiding rod 112 and the second The guide bar 114 is also located on the same side surface 122a of the main body 122. Therefore, the lens module 120 is provided with a bump on only one side and is space-saving in configuration, so that the projection device 100 can have a small volume. In addition, since the first guide bar 112 and the second guide bar 114 are located closer to the same side surface 122a of the main body 122, the mold manufacturing can be more accurately aligned to reduce manufacturing tolerances. In addition, since the first guiding rod 112 and the second guiding rod 114 which are close to each other form a short force arm, when the lens module 120 slides along the first guiding rod 112 and the second guiding rod 114, the lens module 120 can be lowered. The torque generated by assembly and manufacturing tolerances makes the lens module 120 focus more smoothly.
在本實施例中，第一導桿112與第二導桿114之間的距離例如大於或等於0.3毫米，以確保第一導桿112與第二導桿114之間保持足夠的間距，而可有效降低製造公差並降低因組裝及製造公差而產生之力矩。然本發明不對第一導桿112與第二導桿114之間的距離加以限制，在其它實施例中亦可依需求而為其它適當之尺寸設計。此外，本實施例的投影裝置100例如為微型投影裝置(pico projector)，然本發明不以此為限，在其它實施例中，其亦可為其它種類之投影裝置。In this embodiment, the distance between the first guiding rod 112 and the second guiding rod 114 is, for example, greater than or equal to 0.3 mm to ensure a sufficient distance between the first guiding rod 112 and the second guiding rod 114, but Effectively reduce manufacturing tolerances and reduce torque due to assembly and manufacturing tolerances. However, the present invention does not limit the distance between the first guide bar 112 and the second guide bar 114. In other embodiments, other suitable sizes may be designed as needed. In addition, the projection device 100 of the present embodiment is, for example, a pico projector. However, the present invention is not limited thereto, and in other embodiments, it may be other types of projection devices.
請參考圖1，詳細而言，本實施例的光機座110具有開孔116及開孔118，第一導桿112及第二導桿114分別穿設於開孔116及開孔118以進行固定。本發明不對開孔116及開孔118的數量加以限制，舉例來說，開孔116的數量可為兩個且第一導桿112的兩端分別穿設於兩開孔116，開孔118的數量可為兩個且第二導桿114的兩端分別穿設於兩開孔118。Please refer to FIG. 1 . In detail, the optical base 110 of the embodiment has an opening 116 and an opening 118 . The first guiding rod 112 and the second guiding rod 114 are respectively disposed through the opening 116 and the opening 118 for performing. fixed. The present invention does not limit the number of the openings 116 and the openings 118. For example, the number of the openings 116 may be two, and the two ends of the first guiding rod 112 are respectively disposed through the two openings 116, and the openings 118 are The number can be two and the two ends of the second guiding rod 114 are respectively disposed in the two opening holes 118.
圖3為圖2之鏡頭模組、第一導桿與第二導桿的前視圖。請參考圖3，在本實施例中，第二貫孔126a例如為槽孔。第二貫孔126a的第一內徑D1大於第二導桿114的外徑D2，且第二貫孔126a的第二內徑D3大於或等於第二導桿114的外徑D2。藉此，除了可藉由第二貫孔126a將第二凸塊126滑設於第二導桿114之外，更可使第二導桿114與第二貫孔126a具有些微的相對移動自由度，讓整體結構在組裝上較為順利。3 is a front view of the lens module, the first guide bar and the second guide bar of FIG. 2. Referring to FIG. 3, in the embodiment, the second through hole 126a is, for example, a slot. The first inner diameter D1 of the second through hole 126a is larger than the outer diameter D2 of the second guide rod 114, and the second inner diameter D3 of the second through hole 126a is greater than or equal to the outer diameter D2 of the second guide rod 114. Therefore, in addition to the second protrusion 126 being slidably disposed outside the second guiding rod 114 by the second through hole 126a, the second guiding rod 114 and the second through hole 126a have a slight relative movement freedom. To make the overall structure smoother in assembly.
請參考圖1，在本實施例中，第一導桿112例如為主導桿並用以導引鏡頭模組120沿正確的方向相對光機座110移動。兩第一凸塊124分別鄰近第一導桿112的兩端，以穩固地支撐第一導桿112，避免第一導桿112產生傾斜。第二導桿114主要的作用則在於對鏡頭模組120進一步地限位，以避免鏡頭模組120以第一導桿112為轉軸產生旋轉。Referring to FIG. 1 , in the embodiment, the first guiding rod 112 is, for example, a main rod and is used to guide the lens module 120 to move relative to the optical base 110 in the correct direction. The two first bumps 124 are respectively adjacent to both ends of the first guiding rod 112 to stably support the first guiding rod 112 to prevent the first guiding rod 112 from being inclined. The second guiding rod 114 mainly functions to further limit the lens module 120 to prevent the lens module 120 from rotating with the first guiding rod 112 as a rotating shaft.
以下藉由圖4A及圖4B說明圖1之投影裝置的組裝流程。圖4A及圖4B為圖1之投影裝置的組裝流程圖。首先，將鏡頭模組120置於如圖4A所示之位置，並沿方向S將第一導桿112依序插入開孔116及第一貫孔124a至如圖4B所示位置。接著，沿方向S將第二導桿114依序插入開孔118及第二貫孔126a(繪示於圖2)，如圖1所示位置，而完成組裝。The assembly process of the projection apparatus of Fig. 1 will be described below with reference to Figs. 4A and 4B. 4A and 4B are assembly flow charts of the projection apparatus of Fig. 1. First, the lens module 120 is placed at the position shown in FIG. 4A, and the first guiding rod 112 is sequentially inserted into the opening 116 and the first through hole 124a in the direction S to the position shown in FIG. 4B. Next, the second guiding rod 114 is sequentially inserted into the opening 118 and the second through hole 126a (shown in FIG. 2) in the direction S, as shown in FIG.
本發明不對第一凸塊124的數量加以限制。以下藉由圖5對此加以舉例說明。圖5為本發明另一實施例之投影裝置的立體圖。請參考圖5，本實施例的投影裝置200與圖1之投影裝置100的不同處在於，投影裝置200之鏡頭模組220的第一凸塊224的數量為一個。在設計上，可選擇如圖5所示以一個具有較大寬度的第一凸塊224滑設於光機座210的第一導桿212，或選擇如圖1所示以兩個具有較小寬度的第一凸塊124滑設於光機座110的第一導桿112，當然，亦可配置其它適當尺寸與適當數量(例如三個或超過三個)的第一凸塊，本發明不對此加以限制。The present invention does not limit the number of first bumps 124. This is illustrated below by way of FIG. Figure 5 is a perspective view of a projection apparatus according to another embodiment of the present invention. Referring to FIG. 5 , the projection apparatus 200 of the present embodiment is different from the projection apparatus 100 of FIG. 1 in that the number of the first bumps 224 of the lens module 220 of the projection apparatus 200 is one. In the design, as shown in FIG. 5, a first protrusion 212 having a larger width is slidably disposed on the first guide rod 212 of the optical base 210, or selected as shown in FIG. The first protrusion 124 of the width is slidably disposed on the first guiding rod 112 of the optical base 110. Of course, other suitable sizes and a suitable number (for example, three or more than three) of the first protrusions may be disposed, and the present invention is not correct. This is limited.
綜上所述，在本發明的上述實施例中，具有第一貫孔的第一凸塊及具有第二貫孔的第二凸塊位於主體的同一側面，且第一導桿與第二導桿亦相應地位於主體的同一側面。藉此，鏡頭模組僅單側設有凸塊而在配置上較為節省空間，以使投影裝置可具有較小的體積。此外，在本發明的實施例中，由於第一導桿與第二導桿位於主體的同一側面而相距較近，因此在模具製造上可較準確地對位以有效降低製造公差。另外，在本發明的實施例中，由於相距較近的第一導桿與第二導桿之間構成較短的力臂，因此當鏡頭模組沿兩導桿滑動時，可降低因組裝及製造公差而產生之力矩，以使鏡頭模組的調焦較為順暢。In summary, in the above embodiment of the present invention, the first protrusion having the first through hole and the second protrusion having the second through hole are located on the same side of the main body, and the first guide and the second guide The rods are also located on the same side of the body. Thereby, the lens module is provided with a bump on only one side and is space-saving in configuration, so that the projection device can have a small volume. In addition, in the embodiment of the present invention, since the first guide rod and the second guide rod are located close to each other on the same side of the main body, the mold manufacturing can be more accurately aligned to effectively reduce manufacturing tolerances. In addition, in the embodiment of the present invention, since the first guide rod and the second guide rod which are close to each other form a short force arm, when the lens module slides along the two guide rods, assembly and Torque generated by manufacturing tolerances to make the lens module focus more smoothly.
