Referring to FIG. 1, a liquid crystal display (LCD) device in accordance with a preferred embodiment of the present invention includes a bezel 20, an LCD panel 60, and a cover 80. A mounting bracket 22, a first pivot member 26, a movable bracket 30, and a second pivot member 34 are mounted on the bezel 20 via a plurality of screws 38 and 39.
Referring also to FIG. 2, the bezel 20 defines an opening 212 therein. Two notches 202 and 204 are defined in an edge of the bezel 20. A pair of seats 206 each defining a threaded hole is set near the notch 202. A pair of seats 208 each defining a threaded hole is set near the notch 204. Four mounting holes 210 are defined in the bezel at four corners, respectively.
Referring also to FIG. 3, the mounting bracket 22 has a main body 220 having an L-shaped configuration. A mounting plate 222 extends from an end of the main body 220. A pair of apertures 224 is defined in the mounting plate 222. A protruding plate 226 extends perpendicularly from an opposite end of the main body 220. A locking hole 228 is defined in the protruding plate 226. A plurality of bores 230 is defined in the main body 220 adjacent to the mounting plate 222 and the protruding plate 226 respectively.
The first pivot member 26 includes a pivoting portion 260, and a generally T-shaped fixing portion 262. A pair of mounting holes 264 and a through hole 266 are defined in the fixing portion 262 of the first pivot member 26.
Referring also to FIG. 4, the movable bracket 30 includes a main body 300 having an L-shaped configuration. A generally L-shaped mounting plate 302 extends from an end of the main body 300. A pair of elongated adjustment holes 304 and an elongated mounting hole 305 are defined in the mounting plate 302. A protruding plate 306 is bent perpendicularly from an opposite end of the main body 300. An elongated locking hole 308 is defined in the protruding plate 306. A plurality of bores 310 is defined in the main body 300.
The second pivot member 34 includes a pivoting portion 340, and a generally L-shaped fixing portion 342 formed from a cylindrically shaped distal end of the pivoting portion 340. A pair of mounting holes 344 and a through hole 346 are defined in the fixing portion 342 of the second pivot member 34. A partition portion 348 protrudes upward adjacent each mounting hole 344, corresponding to the adjustment holes 304 of the movable bracket 30.
The LCD panel 60 is a thin rectangular parallelepiped. The LCD panel 60 defines a plurality of locking holes 62 in opposite sides thereof, corresponding to the bores 230 of the mounting bracket 22 and bores 310 of the movable bracket 30.
Four fixing poles 82 each defining a threaded hole are set in the cover 80 at four corners, respectively. Two notches 84 and 86 are defined at an edge of the cover 80 corresponding to the notches 202 and 204 of the bezel 20.
Referring to FIGS. 5 to 7, in assembly, two screws 38 are inserted through the mounting holes 264 of the first pivot member 26 and the apertures 224 of the mounting bracket 22, to engage in the corresponding seats 206 of the bezel 20. Thus, the first pivot member 26 and the mounting bracket 22 are mounted to the bezel 20. Two screws 39 are inserted through the mounting holes 344 of the second pivot member 34 and the adjustment holes 304 of the movable bracket 30, to engage in the corresponding seats 208 of the bezel 20. Thus, the second pivot member 34 and the movable bracket 30 are mounted to the bezel 20. At this time, the mounting plate 302 of the movable bracket 30 abuts against the seats 208 of the bezel 20, the fixing portion 342 of the second pivot member 34 is generally positioned above the mounting plate 302, and the partition portions 348 are received in the corresponding adjustment holes 304 of the movable bracket 30. A height of the partition portions 348 is greater than a thickness of the mounting plate 302 of the second pivot member 34, so that the partition portions 348 abut against the corresponding seats 208 of the bezel 20 to raise the fixing portion 342 a distance above the mounting plate 302 of the movable bracket 30. In addition, clearance is provided in the adjustment holes 304 allowing the movable bracket 30 to slide a small distance relative to the bezel 20 in a width direction of the bezel 20 under the guidance of the partition portions 348 of the fixing portions 342.
The LCD panel 60 is placed in a receiving space defined by the bezel 20, the mounting bracket 22 and the movable bracket 30. Because the movable bracket 30 can slide a small distance relative to the second pivot member 34 and the bezel 20, the receiving space defined by the mounting bracket 22 and the movable bracket 30 can be adjusted in width to suit different sized LCD panels 60. Screws are inserted through the bores 230, 310 of the mounting bracket 22 and the movable bracket 30 to engage in the corresponding locking holes 62 of the LCD panel 60. Thus, the LCD panel 60 is mounted to the bezel 20. The LCD panel 60 is visible via the opening 212 in the bezel 20.
To attach the cover 80 to the bezel 20, four fasteners, such as screws 90 are inserted through the mounting holes 210 of the bezel 20, the through hole 266 of the first pivot member 26, the locking hole 228 of the mounting bracket 22, the mounting hole 305 of the movable bracket 30 and the through hole 346 of the second pivot member 34, and the locking hole 308 of the movable bracket 30, to engage in the corresponding fixing poles 82 of the cover 80. The protruding plate 306 and a bounding portion of the mounting hole 305 of the mounting plate 302 of the movable bracket 30 are tightly sandwiched between the bezel 20 and the corresponding fixing poles 82 of the cover 80.
The notch 84 of the cover 80 and the notch 202 of the bezel 20 cooperatively form a first receiving space for receiving the first pivot member 26. The notch 86 of the cover 80 and the notch 204 of the bezel 20 cooperatively form a second receiving space for receiving the second pivot member 34. The LCD device can be pivotably mounted to a base of a notebook computer via the pivoting portion 260 of the first pivot member 26 and the pivoting portion 340 of the second pivot member 34.
When the LCD panel 60 is needed to repair, the screws 90 are unscrewed to allow the cover being detached from the bezel 20. The movable bracket 30 and the mounting bracket 22 are then detached from the LCD panel 60. After that, the LCD panel 60 can be removed from the receiving space via moving the movable bracket 30 away from the LCD panel 60 to thereby release the LCD panel 60, without detaching the mounting bracket 22 and the movable bracket 30 from the bezel 20.
It is to be understood, however, that even though numerous characteristics and advantages of the preferred embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, equivalent material and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
