，當顯示器以腳架置放平面時，VESA掛座處於無用的狀 態’形同浪費。但無論VESA掛座處於作用或無用狀態， VESA掛座在一般設計上只具有單一用途。 時下的行動裝置，比如智慧型手機或平板電腦等， 其性能愈形強大，但其螢幕大小卻只能偈限在適用於手 持的小尺寸。因此，將行動裝置的顯示資訊輸出至相對 為大尺寸的顯示器，將可在使用上提供更大的便利性與 更好的視覺效果。舉例來說，使用平板電腦播放視訊， 表單编號A0101 第3頁/共21頁 M425313 並將此視訊透過傳輸線在相對為大尺寸的顯示器上播放 ;或是，藉由智慧型手機的鏡頭以及與手機連接的相對 為大尺寸的顯示器，進行視訊通話。目前缺乏透過VESA 掛座將相對為大尺寸的顯示器和行動裝置兩者結合的顯 示器延伸結構，若非透過VESA掛座而是透過特製的結構 來連結此兩者，在生1上勢必提高成本，通用性也稍嫌 不足。 【新型内容】 [0004]

(FDMI) standard is developed by the Electronics Standards Association (VESA). Some flat-panel displays are mounted on the VESA mounts with a tripod or pylon, so VESA mounts are used anyway; some are designed with a tripod-specific snap seat on the monitor housing, in which case the monitor When the plane is placed on the tripod, the VESA mount is in a useless state. However, regardless of whether the VESA mount is active or useless, the VESA mount has only a single use in general design. Today's mobile devices, such as smart phones or tablets, are more powerful, but their screen size is limited to the small size that is suitable for handhelds. Therefore, outputting the display information of the mobile device to a relatively large-sized display will provide greater convenience and better visual effects in use. For example, use a tablet to play video, Form No. A0101, Page 3 of 21 M425313 and play the video on a relatively large display through the transmission line; or, with the lens of the smart phone and The relatively large-sized display connected to the mobile phone makes a video call. At present, there is a lack of a display extension structure that combines a relatively large-sized display and a mobile device through a VESA pedestal.

The first accommodating space 120 a The radial cross-sectional area is larger than the control cross-sectional area of the first ambiguous space 120c, and the through hole 12 〇 is located at an inner surface adjacent to the first accommodating space 120crtb, and has a narrowing surface i2〇b 〇 [0020] the through hole 120 The firmware 190 is axially aligned with the firmware 190 for entering from the first accommodating space 120a to make the cylinder 193 be located in the first accommodating space i2 〇 a, while the firmware engaging portion 196 is located in the second accommodating space 120C and The portion having the external thread protrudes from the back surface 11b of the seat. The firmware end face 19〇3 is also recessed with a notch 191 for biasing the fixing tool, for example, the form number A0101, page 8 of 21 [0021], a slotted screwdriver The front end portion is inserted into the slot 191 and rotated. When rotated to the position, the firmware engaging portion 196 can be locked to the display engaging seat 210. In this case, the shoulder portion 194 abuts against the narrowing surface 120b. The base 110 is fixed to the display 200. The placing portion 140 includes a placing surface 140a on which the mobile device 300 is placed, a sliding bracket 160 and a sliding portion 170. The placing surface 140a is provided with a fixing bracket 150, and the sliding bracket 160 is configured to be slidably fitted to the sliding portion 170, so the sliding bracket The distance between the 160 and the fixed bracket 150 can be adjusted according to the size of the mobile device 300, so that the mobile device 300 is firmly held by the sliding bracket 160 and the fixed bracket 150. The placing portion 140 further includes a connecting line 180. One end of the connecting line 180 is electrically connected to the display 200, and the other end is electrically connected to the mobile device 300. The placement portion 140 is disposed at the top edge of the display 200, and the display surface of the mobile device 300 is in the same direction as the display surface of the display 200, so that the user can conveniently view and operate the mobile device 300 and the display 200. For example, the user can use the video camera of the mobile device 300 to perform a video conversation with the screen of the display 200, or use the mobile device 300 to play a movie, and transmit the picture and audio signal to the display 200 to use the screen and display of the display 200. Watch the movie. [0022] Please refer to FIG. 3. FIG. 3 is an exploded view of a display extension structure for combining a mobile device according to another preferred embodiment of the present invention. The base 410 of the display extension structure 400 includes a first engaging portion, the first engaging portion is an engaging groove 411 recessed in the base 410, and the inner peripheral surface 41 la of the engaging groove 411 is convexly provided at least A first engaging element 412, the first engaging element 41 2 is a sheet-like protrusion. The connecting portion 430 includes a second engaging portion corresponding to the first engaging portion. The second engaging portion is a snap-in form number A0101 protruding from the connecting portion 430. Page 9 / 21 pages M425313 column 431, card A second engaging member 432 corresponding to the first engaging member 412 is protruded from the front surface 431b of the pillar, and the second engaging member 432 is an L-shaped projection. In the present embodiment, the inner peripheral surface 4113 of the engaging groove 411 is provided with four first engaging members 412, and correspondingly, the engaging post front surface 43lb is convexly provided with four second engaging members 432. The base 410 and the connecting portion 430 can be separated or connected to the second engaging portion through the second engaging portion. Specifically, when the base 410 and the connecting portion 430 are to be connected, the engaging post 431 is first completely inserted into the engaging groove 411 at an appropriate angle. At this time, the outer peripheral surface 431 of the engaging post 431 and the inner circumference of the engaging groove 411 The surface 411a is adjacent to each other, and then the first engaging element 412 and the second engaging element 432 are engaged with each other by the rotational movement of the engaging post 431 with respect to the engaging groove 411, so that the base 410 and the connecting portion 43 can be stabilized. The connection is integrated; above, the reverse operation can separate the connected body 41〇 from the connection portion 430. [0023] Referring to FIG. 4, FIG. 4 is a schematic diagram of a display extension structure for combining a mobile device according to another preferred embodiment of the present invention. The placement portion 54 of the display extension structure 500 is disposed to be located on the display 2. The side of the cymbal is such that the mobile device 300 is clamped to the side of the display 2 by the fixing bracket 55 〇 and the sliding bracket 560 slidably fitted to the sliding portion 570. In other embodiments, the placement of the display extension structure can be configured to be anywhere on the bottom edge of the display or the perimeter of the display, depending on the design of the different display housings or the needs of the different usage environments. [0024] In summary, the present invention is a display extension structure for combining a mobile device, so that the mobile device can be more conveniently connected with the display to provide a better visual effect and a wider application. Compared with the prior art, it has higher versatility and lower cost of production. Form No. A0101 Page 10 of 21 [0025] Although the present invention has been disclosed in the preferred embodiments as above, it is not intended to limit the present invention, and anyone skilled in the art will not depart from the spirit and scope of the present invention. Within the scope of this patent, the scope of protection of this creation shall be subject to the definition of the scope of the patent application.
