Description

瞳距與屈光度的調節機構Interpupillary distance and diopter adjustment mechanism

本發明係有關一種調節機構，應用於譬如虛擬實境眼鏡，特別是指一種可同時調節控制瞳距與屈光度的調節機構The present invention relates to an adjustment mechanism, which is applied to virtual reality glasses, especially an adjustment mechanism that can simultaneously adjust and control pupil distance and diopter

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, and tend to embrace virtual reality. Virtual reality can provide greater visual satisfaction, making people feel as if they are in it. This experience is unmatched by any previous images or equipment, so it is endowed with considerable high hopes, and relevant manufacturers are all devoted to the relevant Development of technology, equipment 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。One of the key technologies of virtual reality is virtual reality glasses. Virtual reality glasses can provide a complete angle of view, maximize the viewing angle, and generate a scene that surrounds the user to provide the best experience. The environment and the visual feast in it. Low-end virtual reality glasses generally only provide the most basic functions, and can only be regarded as providing users with a preliminary virtual reality experience; while high-end products are not only good for covering, but also for interactive parts. Enhance sensitivity.

然而，針對每個使用者不同的生理狀態，佩帶的虛擬實境眼鏡容易使得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；然而，虛擬實境眼鏡無法針對每個使用者進行客制化的生產，因此具有可調整瞳距與屈光度的虛擬實境眼鏡則因應而生。However, for each user's different physiological state, the wearing of virtual reality glasses is likely to cause discomfort to the user, such as dizziness or the situation where the images cannot be overlapped, and the problem of refractive power is likely to occur in myopic users. The image is difficult to focus or blur; however, virtual reality glasses cannot be customized for each user. Therefore, virtual reality glasses with adjustable interpupillary distance and diopter are developed accordingly.

然而，現有的虛擬實境眼鏡之調整機構皆不盡完善，尤其是難以針對雙眼視差較大的狀況來予以調整。因此，如何針對虛擬實境眼鏡的瞳距與屈光度之調整機構提出改良是一個急需克服的問題。因現在虛擬實境走向輕薄化，以往機構調節方式佔體積及重量，無法使用在新型短焦之虛擬實境眼鏡上，故針對此問題需要進行改良。However, the existing adjustment mechanisms of virtual reality glasses are not perfect, and it is especially difficult to adjust for the situation of large binocular parallax. Therefore, how to improve the interpupillary distance and diopter adjustment mechanism of virtual reality glasses is an urgent problem to be overcome. As the virtual reality is now becoming thinner and lighter, the previous mechanism adjustment method occupies the volume and weight and cannot be used in the new short-focus virtual reality glasses. Therefore, this problem needs to be improved.

有鑒於此，本發明針對現有技術存在之缺失，其主要目的是提供一種瞳距與屈光度的調節機構，不僅能針對瞳距與屈光度進行調整，同時亦可達到單眼個別屈光度的調整，有效提供各種使用者狀況來予以最佳化調校。In view of this, the main purpose of the present invention is to provide an adjustment mechanism for pupil distance and diopter in view of the deficiency in the prior art, which can not only adjust the pupil distance and diopter, but also achieve the adjustment of individual diopter of single eye, effectively providing various The user situation can be optimized and adjusted.

為實現上述目的，本發明提供一種瞳距與屈光度的調節機構，其包含有螺桿與兩調節模組，調節模組可活動地設置於螺桿上，而可藉由轉動螺桿來調整兩調節模組之相對位置，達到瞳距調整的目的。而其中每一調節模組包含有背蓋組件、屏幕組件、鏡片組件與鏡筒組件，背蓋組件具有至少一個螺桿固定件，而可螺設於螺桿，且其上更具有齒輪。屏幕組件則固定於背蓋組件，其上具有直線導槽。鏡片組件可供第一鏡片裝設，其上具有至少一個插銷，穿過直線導槽來裝設於屏幕組件內，並使插銷末端外露於屏幕組件。而鏡筒組件可供第二鏡片裝設，並套設於屏幕組件外，其上具有斜滑槽，供外露之插銷穿過，且其外表面具有耦合於背蓋組件之齒輪的鏡筒齒輪。In order to achieve the above objective, the present invention provides an adjustment mechanism for pupil distance and diopter, which includes a screw and two adjustment modules. The adjustment module can be movably arranged on the screw, and the two adjustment modules can be adjusted by rotating the screw. Its relative position can achieve the purpose of interpupillary distance adjustment. Each adjustment module includes a back cover assembly, a screen assembly, a lens assembly, and a lens barrel assembly. The back cover assembly has at least one screw fixing member, which can be screwed on the screw and has a gear on it. The screen assembly is fixed to the back cover assembly and has a linear guide groove on it. The lens assembly can be used for the installation of the first lens. At least one pin is provided on the lens assembly, which passes through the linear guide groove to be installed in the screen assembly, and the end of the pin is exposed to the screen assembly. The lens barrel assembly can be used for mounting the second lens and sleeved outside the screen assembly. It has an oblique sliding groove for the exposed pins to pass through, and its outer surface has a lens barrel gear coupled to the gear of the back cover assembly .

因此，藉由轉動背蓋組件之齒輪，使其帶動鏡筒齒輪作動而使鏡筒組件轉動，藉由插銷與斜滑槽的限位，鏡筒組件會與鏡片組件產生相對位移，進而改變第一鏡片與第二鏡片的相對位置，達到單眼屈光度的調整，便於解決左右眼度數不同時不清楚畫面的問題。Therefore, by rotating the gear of the back cover assembly to drive the lens barrel gear to act, the lens barrel assembly rotates. By the limit of the latch and the oblique sliding groove, the lens barrel assembly and the lens assembly will have a relative displacement, thereby changing the The relative position of the first lens and the second lens can adjust the diopter power of one eye, which is convenient to solve the problem of unclear picture when the power of left and right eyes is different.

首先，針對瞳距的調整，請參閱第三圖，螺桿10之左螺紋螺桿11與右螺紋螺桿12係具有不同轉向的螺紋，因為第一調節模組21與第二調節模組22分別設置於左螺紋螺桿11與右螺桿螺桿12，因此當使用第一調節輪101來控制螺桿10的轉動時，第一調節模組21與第二調節模組22則會以不同方向運動，進而改變第一調節模組21與第二調節模組22的相對位置，達到調整瞳距的目的，因而能解決不同使用者配戴的不舒適感受，譬如如頭暈或影像無法重合之狀況。First, for the adjustment of the interpupillary distance, please refer to the third figure. The left threaded screw 11 and the right threaded screw 12 of the screw 10 have threads with different rotations, because the first adjustment module 21 and the second adjustment module 22 are respectively arranged in The left screw screw 11 and the right screw screw 12, so when the first adjusting wheel 101 is used to control the rotation of the screw 10, the first adjusting module 21 and the second adjusting module 22 will move in different directions, thereby changing the first The relative position of the adjusting module 21 and the second adjusting module 22 achieves the purpose of adjusting the interpupillary distance, and thus can solve the discomfort of different users, such as dizziness or the situation where the images cannot be overlapped.

接續針對屈光度的調整，請配合第四、五、六圖，第一調節模組21藉由第二調節輪2142來使背蓋組件214之齒輪2143轉動，因鏡筒齒輪2112耦合於齒輪2143，因此會受到齒輪2143的帶動，而使整個鏡筒組件211轉動，此時，因為插銷2121、直線導槽2131、斜滑槽2111的限位關係，加上屏幕組件213是固定於背蓋組件214，因而會使得鏡筒組件211轉動過程中，插銷2121會沿著斜滑槽2111與直線導槽2131來進行運動，因而推動鏡筒組件211向外運動，使鏡筒組件211會與鏡片組件212產生相對位移，連帶也就會使得裝設於鏡筒組件211的第二鏡片42與裝設於鏡片組件212的第一鏡片41產生相對位置、距離的改變，因而能調整其焦距與成像位置，達到調整屈光度的目的。To continue the adjustment of the diopter, please follow the fourth, fifth and sixth figures. The first adjustment module 21 uses the second adjustment wheel 2142 to rotate the gear 2143 of the back cover assembly 214, because the lens barrel gear 2112 is coupled to the gear 2143. Therefore, it is driven by the gear 2143 to rotate the entire lens barrel assembly 211. At this time, because of the limit relationship of the latch 2121, the linear guide groove 2131, the inclined sliding groove 2111, and the screen assembly 213 is fixed to the back cover assembly 214 Therefore, during the rotation of the lens barrel assembly 211, the latch 2121 will move along the inclined sliding groove 2111 and the linear guide groove 2131, thus pushing the lens barrel assembly 211 to move outwards, so that the lens barrel assembly 211 and the lens assembly 212 The relative displacement will also cause the relative position and distance of the second lens 42 installed in the lens barrel assembly 211 and the first lens 41 installed in the lens assembly 212 to change, so that the focal length and imaging position can be adjusted. To achieve the purpose of adjusting the diopter.

再者，因為是藉由斜向延伸之斜滑槽2111與軸向配置之直線導槽2131來配合插銷2121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。Furthermore, because the oblique sliding groove 2111 and the axially arranged linear guide groove 2131 are used to cooperate with the plug 2121 for control, the stability of the overall adjustment mechanism is quite high, which can achieve high and precise control and Adjustment.

另一方面，第二調節模組22的調整方式也是相同，在此不重複贅述，由於兩調整模組為個別獨立的調整，因此針對使用者而言，即可針對兩眼不同的視力狀況來分別進行屈光度調整，適用於來解決左右眼度數不相同的用戶看不清楚畫面的問題。On the other hand, the adjustment method of the second adjustment module 22 is also the same, which will not be repeated here. Since the two adjustment modules are adjusted individually and independently, for the user, the eyesight can be adjusted for different eyesight conditions. Adjust the diopter separately, which is suitable for solving the problem that users with different degrees of left and right eyes cannot see the picture clearly.

唯以上所述者，僅為本發明之較佳實施例而已，並非用來限定本發明實施之範圍。故即凡依本發明申請範圍所述之特徵及精神所為之均等變化或修飾，均應包括於本發明之申請專利範圍內。Only the above are merely preferred embodiments of the present invention, and are not used to limit the scope of the present invention. Therefore, all equivalent changes or modifications made in accordance with the characteristics and spirit of the application scope of the present invention shall be included in the patent application scope of the present invention.
