全方位視角之樞軸調整機構Pivot adjustment mechanism for omnidirectional view

本發明係有關本發明係有關一種全方位視角之樞軸調整機構，尤指一種可調整螢幕面板之仰角及水平視角，而可增進使用方便性的調整機構。The present invention relates to a pivot adjustment mechanism for a omnidirectional viewing angle, and more particularly to an adjustment mechanism that can adjust the elevation angle and horizontal viewing angle of the screen panel to improve the usability.

依目前所知螢幕面板的支撐結構多為固定式結構，該固定式結構並無法調整螢幕面板的仰角或是水平視角，於使用上非常不便，因而造成使用者的困擾。有鑑於此，已有相關業者開發出一種可調整支撐螢幕面板斜度結構，其中，結構形態係為一固定之架體頂部設成弧狀之結構，並於其弧形之架體頂部另設有一螢幕面板支架，如此之結構，其雖其螢幕面板可沿架體而調整，惟其架體固定，且相當佔用空間，仍佔據桌面相當大之空間，尤其目前平板式之電腦已風行許久，其電腦螢幕面板必須時常被拿起來作書寫或畫圖之用，因此固定式之架體已不符實用性者。As far as is known, the support structure of the screen panel is mostly a fixed structure, and the fixed structure cannot adjust the elevation angle or the horizontal viewing angle of the screen panel, which is very inconvenient to use, thereby causing trouble to the user. In view of this, related companies have developed an adjustable support screen panel slope structure, wherein the structure is a fixed frame body with an arc-shaped structure at the top, and is provided at the top of the curved frame body. There is a screen panel bracket. With such a structure, although the screen panel can be adjusted along the frame body, the frame body is fixed and takes up a lot of space, and still occupies a considerable space of the desktop. In particular, the tablet type computer has been popular for a long time. Computer screen panels must always be picked up for writing or drawing, so the fixed frame is no longer practical.

另有相關業者於螢幕面板背面或底面設有承載之支撐結構，惟，其結構複雜度甚高，成本上十分的昂貴，更無法供使用者直接攜帶取置，故使用上仍有其不便之處者。亦有業者發展腳座與螢幕面板係可分離之形態，腳座上設有可調整角度之結構，惟由於其係於螢幕面板與腳座間形成一相互插置之結構形態。In addition, the relevant manufacturers have a supporting structure on the back or the bottom of the screen panel. However, the structure is very complicated, the cost is very expensive, and it is not convenient for the user to directly carry it. Therefore, the use is still inconvenient. The person. There are also manufacturers who can develop a form in which the foot and the screen panel can be separated. The foot has an adjustable angle structure, but the structure is formed by interposing between the screen panel and the foot.

另有一種習用結構如專利第M335104號『具電控俯仰角度調整構造的平面顯示器架體』，其包含一支撐柱、一傳動裝置以及一螢幕固定架，該傳動裝置固定於該支撐柱之表面，其包含一馬達模組以及一活動臂，該活動臂活動插設於該馬達模組；該馬達模組可接受外部控制訊號之控制而改變該活動臂對該馬達模組的延伸長度；該螢幕固定架，其局部樞接於該支撐柱表面，且其一端與該活動臂的自由端樞接，其另一端可擺動並凸出於該支撐柱；使用時，可將一平面顯示器固定於該螢幕固定架上，藉由控制該馬達模組，即可調整該平面顯示器的俯仰角度。Another conventional structure is disclosed in Patent No. M335104, "Flat Display Frame Body with Electronically Controlled Pitch Angle Adjustment Structure", which comprises a support column, a transmission device and a screen fixing frame, and the transmission device is fixed on the surface of the support column. The motor module and a movable arm are movably inserted in the motor module; the motor module can control the extension of the movable arm to the motor module by controlling the external control signal; The screen holder is partially pivotally connected to the surface of the support column, and one end thereof is pivotally connected to the free end of the movable arm, and the other end of the screen is pivoted and protrudes from the support column; in use, a flat display can be fixed to The pitch angle of the flat display can be adjusted by controlling the motor module on the screen holder.

該習用結構雖然具有電控調整平面顯示器之俯仰角度功能，惟，其並無電控調整平面顯示器之水平視角功能，因而造成使用上的不便與困擾。Although the conventional structure has the function of tilting the angle of the electronically controlled flat panel display, it has no electronic control to adjust the horizontal viewing angle function of the flat panel display, thereby causing inconvenience and trouble in use.

又有一種習用結構如專利第M333736號『可改變視角之電腦螢幕座』其包括一具有收納空間之收納體，該收納體上具有不同長度且兩兩相對之固定件，該各固定件分別供兩配合件及兩活動體樞設，該各配合件及活動體之另端樞設於一螢幕之相對側邊，藉由上述結構相互樞設配合，並供使用者能夠改變觀看螢幕之視覺角度變化，達到提供使用者高實用性及便利性之目的者。There is also a conventional structure such as Patent No. M333736, "Computer screen holder for changing the viewing angle", which comprises a storage body having a storage space having different lengths and two opposite fixing members, respectively. The two engaging members and the two movable bodies are pivoted, and the other ends of the engaging members and the movable body are pivotally disposed on opposite sides of a screen, and the structures are pivotally matched with each other, and the user can change the viewing angle of the screen. Change to achieve the purpose of providing users with high practicality and convenience.

該習用結構雖然具有手動調整顯示器之俯仰角度以及升降高度之功能，惟，其並無電控調整平面顯示器之水平視角功能，而且其係整合於電腦桌上，於實際生產時會增Although the conventional structure has the function of manually adjusting the pitch angle and the lifting height of the display, it has no electronic control to adjust the horizontal viewing angle function of the flat panel display, and the system is integrated on the computer table, which is increased in actual production.

加組裝工時，因而造成使用上的不便、困擾以製造成本的增加。The assembly time is increased, which causes inconvenience in use and troubles to increase the manufacturing cost.

有鑑於此，本發明乃使螢幕面板之傾斜度支撐調整角度範圍更為大，以別於一般螢幕面板之樞軸，故利用蝸桿、齒輪與凸輪之整合，乃開發出一種符合全方位視角之一種螢幕面板傾斜度及水平視角控制機構。In view of the above, the invention makes the tilting support adjustment angle range of the screen panel larger than the pivot of the general screen panel, so the integration of the worm, the gear and the cam is developed to conform to the omnidirectional perspective. A screen panel tilt and horizontal viewing angle control mechanism.
