參以及連接背板20傳遞到連接支架325，當推力對轉轴321 之力矩克服連接支架325與限位片322間之摩擦力矩時， 連接支架325繞轉軸321轉動，顯示幕框架10後仰，其與 支撐架40之間之夾角增大。由於彈性件323扭矩與顯示幕 框架10之重力矩基本平衡，該推力可較小，從而便於操作。 外力撤銷後，顯示裝置100於顯示幕框架10之重力、支撐 架40之支撐力、支撐平台之支撐力、連接支架325與限位 片322間之摩擦力以及彈性件323產生之扭力作用下保持 平衡，從而可停留於預設之位置上。本實施例中，最大之 12 201011195 後仰角度為15度。轉動過程中，限位件322之限位部3224 於連接支架325之限位槽3259中轉動，限位部3224旋轉 一定角度後與限位槽3259内侧壁相抵擋，從而限定顯示幕 框架10之轉動角度範圍。 與上述過程相似，欲減小顯示幕框架10與支撐架40 間之夾角’可於顯示幕框架頂部施加一較小之拉力，當 該拉力產生之力矩克服連接支架325與限位片322間之摩 ❹擦力矩時’顯示幕框架1〇前傾。於本實施例中，最大之前 傾角度為5度。 可以理解，彈性件323也可為其他類型彈性體，比如 拉簧或橡膠件等。樞轉元件30也可僅包括一樞轉單元32, 並將樞轉單元32設於轉動支架31上。 本發明顯示裝置1〇〇具有以下優點：（1)顯示幕框架 10之支撐部112與支撐架40形成人字型支撐結構，顯示幕 框架10之重力主要作用於支撐平台上，支撐架40所承受 _之作用力相對較小’從而可支撐具有較大重量之顯示裝置 WO。（2)彈性件323產生之扭矩與顯示幕框架1〇之重力 矩基本平衡，只需施加較小之作用力克服摩擦力矩即可調 整顯示幕框架10之俯仰角度，便於操作，且摩擦元件受到 之作用力較小，使用壽命較長。（3)顯示幕框架1〇與支撐 架40形成人字型支撐結構支撐於支撐平台上，此種結構穩 疋性較好，不易產生晃動’且結構簡單緊湊，所使用之元 件數量較少，降低了成本，並方便運輸和攜帶。（4)連接 方板20與樞轉元件3〇間藉由插拔方式連接，可實現快速 13 201011195 安裝和拆卸，便於使用。 當然，本發明顯示裝置100還可用於LCD(Liquid Crystal Display，液晶顯示幕）、PDP(Plasma

When the thrust is sufficient to overcome the friction between the friction plate and the connecting frame, the display screen can be pivoted and balanced by the friction generated by the friction between the friction plate and the connecting bracket. The curtain weight is displayed so that the display stays at the preset tilt angle position. However, in the above display device, the display screen frame is disposed above the chassis, and its gravity is completely applied to the connecting frame and the pivot shaft, and the heavy moment is balanced by the moment generated by the friction between the friction plate and the connecting frame. With the above structure, there is a big change in the display, such as the large size of the show or the internal display of a computer monitor with a computer, and the adjustment of the display pitch angle of 201011195 degrees, It is necessary to increase the strength of the connecting frame and the pivot to withstand greater gravity, which will increase the size and cost of the structure. In addition, a larger friction torque is required to balance the heavy torque, so that a large force is applied to overcome the friction torque, the use is inconvenient, and the friction member is easily damaged and the service life is shortened. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a display device that can support a large weight display screen and that can easily adjust the pitch angle of the display screen.

In the above process, the connection backboard 20 and the connection bracket 325 are connected and separated by plugging and unplugging, and the operation is convenient, and the quick installation and disassembly can be realized. The function and method of use of the display device 100 of the present invention are described in detail below. Referring to FIG. 1 to FIG. 3 again, the support portion 112 of the curtain frame 10 and the support frame 40 form a herringbone support structure to support the display device 100. The position of the center of gravity of the display screen frame 10 is located on the rotating shaft 321 in the vertical direction. 11 201011195 The horizontal direction is located between the support portion 112 and the support frame 40 and the support point of the support platform. The center of gravity of the support frame 40 is located below the rotating shaft 321. The display frame 10 is balanced by its heavy moment, the torque generated by the elastic member 323, and the frictional moment between the limiting piece 322 and the connecting bracket 325, thereby staying at the set position. Wherein, the heavy moment of the display screen frame 10 causes the support portion 112 to have a tendency to be away from each other with respect to the support frame 40, that is, the tendency of the angle between the large display screen 10 and the support frame 40, and the torque generated by the elastic member 323 can be made. The rotating bracket 31 and the connecting bracket 325 have a tendency to be close to each other, and the generated torque can be substantially balanced with the weight of the display screen frame 10. During the rotation of the display frame 10 relative to the pivoting assembly 30, the heavy moment of the display screen frame 10 and the torque generated by the elastic member 323 have substantially the same change trend, and the difference between the two can be obtained by the limiting piece 322 and the connecting bracket. The frictional distance between 325 is compensated. To increase the angle between the display frame 10 and the support frame 40, a thrust is applied to the top of the display frame 10, and the thrust is transmitted to the connection bracket 325 through the display frame 10 and the connection back plate 20, when the thrust is opposite to the shaft When the torque of 321 overcomes the frictional torque between the connecting bracket 325 and the limiting piece 322, the connecting bracket 325 rotates around the rotating shaft 321, and the display frame 10 is tilted back, and the angle between the supporting frame 40 and the supporting frame 40 is increased. Since the torque of the elastic member 323 is substantially balanced with the weight of the display screen frame 10, the thrust can be made small to facilitate the operation. After the external force is cancelled, the display device 100 is held by the gravity of the display screen frame 10, the supporting force of the support frame 40, the supporting force of the supporting platform, the friction between the connecting bracket 325 and the limiting piece 322, and the torque generated by the elastic member 323. Balance so that you can stay at the preset position. In this embodiment, the maximum 12 201011195 recoil angle is 15 degrees. During the rotation, the limiting portion 3224 of the limiting member 322 rotates in the limiting slot 3259 of the connecting bracket 325, and the limiting portion 3224 rotates at a certain angle to resist the inner sidewall of the limiting slot 3259, thereby defining the display screen frame 10. Rotation angle range. Similar to the above process, the angle between the display frame 10 and the support frame 40 can be reduced to apply a small pulling force on the top of the display frame frame, and the moment generated by the tension overcomes the connection between the connecting bracket 325 and the limiting piece 322. When the friction is rubbed, the display frame is tilted forward. In the present embodiment, the maximum rake angle is 5 degrees. It will be appreciated that the resilient member 323 can also be other types of elastomers, such as tension springs or rubber members. The pivoting member 30 can also include only one pivoting unit 32 and the pivoting unit 32 can be disposed on the rotating bracket 31. The display device 1 of the present invention has the following advantages: (1) the support portion 112 of the display screen frame 10 and the support frame 40 form a herringbone support structure, and the gravity of the display screen frame 10 mainly acts on the support platform, and the support frame 40 The force with which the force is relatively small 'is thus able to support the display device WO having a larger weight. (2) The torque generated by the elastic member 323 is substantially balanced with the weight of the display screen frame 1 , and the pitch angle of the display screen frame 10 can be adjusted by applying a small force to overcome the friction torque, which is convenient for operation and the friction element is subjected to The force is small and the service life is long. (3) The display screen frame 1〇 and the support frame 40 form a herringbone support structure supported on the support platform, and the structure has good stability, is not easy to cause shaking, and has a simple and compact structure, and the number of components used is small. Reduce costs and facilitate transportation and carrying. (4) Connection The square plate 20 and the pivoting member 3 are connected by plugging and unplugging, which can realize the quick installation and disassembly of the 2010-11195, which is convenient to use.
