Description

屈光度可調的鏡頭模組Diopter-adjustable lens module

本創作是有關於一種虛擬實境設備，特別是指一種應用於虛擬實境眼鏡的屈光度可調的鏡頭模組。This creation is about a virtual reality device, especially a lens module with adjustable diopter applied to virtual reality glasses.

近年來，隨著虛擬實境技術的成熟，人們不再滿足於3D影像，而趨於朝向虛擬實境的懷抱。虛擬實境能提供更大的視覺滿足，使人們彷彿置身於其中，此種體驗是之前任何影像或是設備所無法比擬，因此被賦與相當大的厚望，也使得相關廠商無不全力投入相關技術、裝置與零組件的開發。In recent years, with the maturity of virtual reality technology, people are no longer satisfied with 3D images, but tend to embrace virtual reality. Virtual reality can provide greater visual satisfaction and make people feel as if they are in it. This experience is unmatched by any previous image or equipment, so it is endowed with considerable expectations, and related manufacturers are all devoted Development of technologies, devices and components.

而虛擬實境其中一個關鍵技術在於虛擬實境眼鏡，藉由虛擬實境眼鏡能提供完整的視場角，使得觀看的角度最大化，能夠產生包圍使用者的場景，才能提供最佳的身歷其境與置身其中的視覺饗宴。低階的虛擬實境眼鏡一般只能提供最基礎的功能，只能視為提供使用者初步虛擬實境體驗之用；而中高階產品不僅包覆性好，同時也能針對互動性的部份增強感受性。其中，針對每個使用者不同的生理狀態，虛擬實境眼鏡容易讓使用者產生不適的感覺，如頭暈或影像無法重合之狀況，而屈光度的問題容易產生於近視的使用者，會產生影像難以對焦或模糊的狀況，但是虛擬實境眼鏡無法針對每個使用者進行客制化的生產，因此可調整屈光度的虛擬實境眼鏡則因應而生。One of the key technologies of virtual reality is virtual reality glasses. The virtual reality glasses can provide a complete field of view, maximize the viewing angle, and generate scenes that surround the user, so as to provide the best experience. The environment and the visual feast of being in it. Low-end virtual reality glasses generally can only provide the most basic functions, and can only be regarded as providing users with a preliminary virtual reality experience; while high-end products not only have good coverage, but also can target the interactive part. Enhance susceptibility. Among them, according to the different physiological states of each user, the virtual reality glasses can easily make the user feel uncomfortable, such as dizziness or the situation that the images cannot be overlapped, and the problem of diopter is easy to occur in myopic users, which will produce difficult images. Focus or blur, but virtual reality glasses cannot be customized for each user, so virtual reality glasses with adjustable diopter are born accordingly.

然而，現有的虛擬實境眼鏡之屈光度調整機構皆不盡完善，尤其目前虛擬實境眼鏡的主要趨勢為具備超短焦鏡頭模組，且使用屏幕尺寸與鏡片可視區越大，則鏡片外型也越大，造成整體模組外型設計偏大，而當整體模組外型越大，穿戴時容易導致人臉干涉問題。如第1圖所示的鏡片組裝結構，以往鏡頭模組中的屈光度調整機構須將鏡片10組裝於例如間隔環101等額外的機構件內，藉由此間隔環101的外側設有多個圓柱狀的限位結構102，以便於進行模組調焦，也因機構件的存在使得整體模組外型變大，同時也導致鏡片10嵌合以及調焦不穩定性等問題。However, the diopter adjustment mechanism of the existing virtual reality glasses is not perfect, especially the main trend of the current virtual reality glasses is to have an ultra-short-focus lens module, and the larger the screen size and the visible area of the lens, the better the shape of the lens. The larger the size, the larger the overall module appearance design, and when the overall module appearance is larger, it is easy to cause the problem of face interference when wearing. As shown in the lens assembly structure shown in FIG. 1, the diopter adjustment mechanism in the conventional lens module requires the lens 10 to be assembled in an additional mechanism such as a spacer ring 101, and a plurality of cylinders are arranged on the outside of the spacer ring 101. The shape of the limiting structure 102 is convenient for the focusing of the module, and the presence of the mechanical components makes the overall appearance of the module larger, and also causes problems such as the fitting of the lens 10 and the instability of focusing.

因此，如何針對虛擬實境眼鏡中鏡頭模組的屈光度調整機構提出改良是一個急需克服的問題。Therefore, how to improve the diopter adjustment mechanism of the lens module in the virtual reality glasses is an urgent problem to be overcome.

有鑑於此，本創作的主要目的在於提供一種屈光度可調的鏡頭模組，藉由直接在調焦鏡片邊緣凸設有至少一限位部，無須組裝額外的機構件，可使整體模組外型縮小，並可減少人臉干涉問題。In view of this, the main purpose of this creation is to provide a lens module with adjustable diopter.

更進一步說明本創作之調焦鏡片11，請參照第5圖和第6圖，其分別為本創作之實施例的調焦鏡片11的示意圖和側視圖。本實施例中，調焦鏡片11邊緣凸設限位部111，無須組裝額外的機構件，可使整體模組外型縮小，解決人臉干涉問題。再者，本實施例於調焦鏡片11邊緣設置有一遮光區域112，此遮光區域112為黑色油墨層，且限位部111位於遮光區域112，可避免鏡片邊緣造成影像不良之光反射。For further description of the focusing lens 11 of the present invention, please refer to FIG. 5 and FIG. 6 , which are a schematic diagram and a side view of the focusing lens 11 according to the embodiment of the present invention, respectively. In this embodiment, the limiting portion 111 is protruded from the edge of the focusing lens 11 , so that no additional mechanical components are required to be assembled, so that the appearance of the overall module can be reduced, and the problem of human face interference can be solved. Furthermore, in this embodiment, a light-shielding area 112 is disposed on the edge of the focusing lens 11 . The light-shielding area 112 is a black ink layer, and the limiting portion 111 is located in the light-shielding area 112 , which can avoid light reflection caused by the edge of the lens to cause poor images.

針對屈光度的調整，請配合第2圖至第4圖，藉由轉動調焦環30，使得直線導槽31跟著轉動，此時，因為限位部111、直線導槽31、斜滑槽21的限位關係，因而使得調焦環30的轉動過程中，直線導槽31會帶動限位部111沿著直線導槽31與斜滑槽21中移動，且由於鏡筒組件40固定於鏡片支架20上，使調焦鏡片11與固定鏡片12產生相對位移，因而能調整其焦距與成像位置，達到調整屈光度的目的。其中，因為是藉由斜向延伸之斜滑槽21與軸向配置之直線導槽31來配合限位部111進行控制，因此整體調整機制的穩定度相當高，能夠達到較高且精密的控制與調整。For the adjustment of the diopter, please refer to Fig. 2 to Fig. 4. By rotating the focusing ring 30, the linear guide groove 31 rotates accordingly. Therefore, during the rotation of the focus ring 30 , the linear guide groove 31 will drive the limiting portion 111 to move along the linear guide groove 31 and the oblique sliding groove 21 , and the lens barrel assembly 40 is fixed to the lens holder 20 On the other hand, the focusing lens 11 and the fixed lens 12 are relatively displaced, so that the focal length and imaging position can be adjusted to achieve the purpose of adjusting the diopter. Among them, because the oblique chute 21 extending obliquely and the linear guide groove 31 arranged in the axial direction cooperate with the limiting portion 111 for control, the stability of the overall adjustment mechanism is quite high, and high and precise control can be achieved with adjustment.

綜上所述，根據本創作所提供的屈光度可調的鏡頭模組，藉由直接在調焦鏡片邊緣凸設有至少一限位部，不需要組裝額外的機構件，可以簡化結構，減輕模組重量，使整體模組外型的尺寸可以縮小，避免穿戴時與人體之鼻樑干涉的問題，且方便整機廠商設計。再者，由於調焦鏡片不需要與額外的機構件進行結合，可以降低模組組裝的工時、成本以及組裝公差，省去實配嵌合的問題，同時可讓調焦的穩定性（包括同軸度、平面度）得以提高，從而提高觀影效果。To sum up, according to the lens module with adjustable diopter provided by the present invention, by directly protruding at least one limiting portion on the edge of the focusing lens, there is no need to assemble additional mechanical components, the structure can be simplified, and the mold can be reduced. The weight of the group can reduce the overall size of the module, avoid the problem of interference with the nose bridge of the human body when wearing it, and facilitate the design of the whole machine manufacturer. Furthermore, since the focusing lens does not need to be combined with additional mechanical components, the man-hours, costs and assembly tolerances of module assembly can be reduced, the problem of fitting and fitting is eliminated, and the stability of focusing (including Concentricity, flatness) can be improved, thereby improving the viewing effect.
