BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates in general to a panel-fixing device, and more particularly to the panel-fixing device for fixing a panel at a casing of an electronic device.
2. Description of the Related Art
Nowadays, the flat display has become an essential part of people's daily life, and widely applied to a liquid crystal display TV, a mobile phone, a desktop computer, a screen of the notebook, a screen of the personal digital assistant (PDA) and a screen of the voice recorder in the modern time.
Typically, the panel of the flat display is disposed on the front casing of the electronic device. In the traditional manufacturing process, the size of the casing is designed based on the panel size prospectively. If the front casing is designed and produced precisely based on the panel size, the panel can be fixed tightly at the front casing without shaking. However, comparing to the panels having the same size (ex: 17″ panel), it has a considerable issue that the precise dimensions of panels would be slightly different from each other if those panels are fabricated by the different manufacturers and/or the manufacturing processes. Traditional method of solving the issue is reproducing and redesigning the matching casing based on the sizes of panels. In some traditional methods, some mechanical films with adequate size can be selected and added to the fixing component of the front casing for the purpose of fitting the panel into the front casing. However, these conventional methods require long labor hours and complicated manufacturing process, and therefore increase the manufacturing cost of panel production.

DETAILED DESCRIPTION OF THE INVENTION
This invention is related to a panel-fixing device and an electronic device applied with the same. The panel-fixing device is designed as a movable engaged device. When the panels with slightly different sizes are assembled to a common casing, the panel-fixing device adjustably fixes those panels at its own suitable fixing position and height. The mechanical design of the present invention has several advantages such as quick assembly (i.e. saving assembly time), simplification of the manufacturing process (i.e. without fabricating different casing for those panels), and decrease of production cost (ex: a casing could be commonly used for fitting the panels having slightly different dimensions due to the novel panel-fixing device).
Please refer to FIG. 1A and FIG. 1B. FIG. 1A shows a panel-fixing device assembled to an electronic device of the preferred embodiment according to the invention. FIG. 1B is a cross-sectional view of the panel-fixing device assembled to the electronic device in FIG. 1A. The electronic device 200 includes a casing 210, a panel 220 and at least one panel-fixing device. Panel 220 is disposed on the casing 210. The panel-fixing device is used for fixing the panel 220 at the casing 210. The panel-fixing device includes a receiving portion 230 and a clipping portion 240. The receiving portion 230, which includes several positioning components 232, is disposed on the casing 210. The clipping portion 240, which is movable engaged with the receiving portion 230, includes a hooking component 242, an adjusting component 244 and a fixing plane 246. When the clipping portion 240 is engaged with the receiving portion 230, the hooking component 242 catches one of the positioning components 232 for fixing the clipping portion 240. The adjusting component 244 is substantially parallel to the hooking portion 242. The fixing plane 246 is substantially vertically connected to the adjusting component 244. When the clipping portion 240 is engaged with the receiving portion 230, the fixing plane 246 presses against the bottom surface of the panel 220 for fixing the panel 220 to the casing 210.
Please refer to FIG. 2A to FIG. 2C. FIG. 2A is a perspective view of the clipping portion of the preferred embodiment according to the invention. FIG. 2B is a top view of the clipping portion in FIG. 2A. FIG. 2C is a cross-sectional view of the clipping portion in FIG. 2A. The panel-fixing device for fixing the panel 220 of the electronic device 200 at the casing 210 includes a receiving portion 230 and a clipping portion 240, wherein the clipping portion 240 is movably engaged with the receiving portion 230. As shown in FIG. 2A to FIG. 2C, the clipping portion 240 includes a hooking component 242, a fixing plane 246, an adjusting component 244 and several projecting ribs 248. The hooking component 242 includes a hooking plane 243 and an elastic handle 245 connected to the hooking plane 243. The adjusting component 244 and the hooking component 242 are substantially parallel to each other, and the fixing plane 246 is substantially vertically connected to the adjusting component 244. The clipping portion 240 includes several projecting ribs 248 which are substantially disposed on the inner side 241 of the clipping portion 240 vertically. In the practical manufacturing processes, the hooking component 242, the fixing plane 246, the adjusting component 244, and the projecting ribs 248 could be formed as one-piece structure (i.e. integrated as a whole) and made of an elastic material such as plastic.
Please refer to FIG. 3A and FIG. 3B. FIG. 3A shows the receiving portion disposed on the casing of the preferred embodiment according to the invention. FIG. 3B is a cross-sectional view of the receiving portion disposed on the casing in FIG. 3A. The receiving portion 230, disposed on the casing 210, includes several positioning components 232, a first wall 234, a second wall 236 and several grooves 238. In the practical applications, the positioning components 232, the first wall 234, the second wall 236, several grooves 238 and the casing 210 could be formed as a one-piece structure. As shown in FIG. 3A, the first wall 234 is substantially parallel to the second wall 236. The positioning components 232 are disposed between the first wall 234 and the second wall 236, and the positioning components 232 are individually connected to the first wall 234 and the second wall 236. Also, the positioning components 232 are individually vertical to the first wall 234 and the second wall 236. In the embodiment, several hooking ribs are substantially parallel to the first and second walls 234/236 are exemplified as the positioning components 232. The grooves 238 are individually and substantially vertically formed on the outsides of the first wall 234 and the second wall 236.
Please refer to FIG. 1A and FIG. 1B again. When the clipping portion 240 and receiving portion 230 are engaged to each other, the clipping portion 240 is used for fixing the panel 220 at the casing 210. The casing 210 has an inner wall 212 for separating the casing 210 into a first space sp1 and a second space sp2 (see FIG. 1B). A first distance d is between the panel 220 and the inner wall 212, wherein a thickness of the adjusting component 244 is corresponding to the first distance d. While the adjusting component 244 is inserted between the panel 220 and the inner wall 212, the fixing plane 246 of the clipping portion 240 presses against the bottom surface of the panel 220. Then, the hooking plane 243 of the hooking component 242 catches one rib of positioning components 232, thereby fixing the panel 220 to the casing 210. After the clipping portion 240 is engaged with the receiving portion 230, the movement of the panel 220 in the x-direction is limited, since the thickness of the adjusting component 244 is corresponding to the first distanced d. Also, the fixing plane 246 pressing against the bottom surface of the panel 220 limits the movement of the panel 220 in the z-direction.
Thus, when the clipping portion 240 is engaged with the receiving portion 230, the hooking component 242 is positioned in the second space sp2, the adjusting component 244 located between the panel 220 and the inner side 212 is positioned in the first space sp1, and the fixing plane 246 which is against the panel 220 is positioned in the first space sp1 (see FIG. 1B). Furthermore, the clipping portion 240 and receiving portion 230 use an elastic handle 245 to achieve the objective of removable engagement. As shown in FIG. 1B, the elastic handle 245 of the hooking component 242 is connected to the hooking plane 243. When the elastic handle 245 is pushed by an external force, the hooking plane 243 is removed (apart) from the corresponding rib (i.e. corresponding positioning component 232), such that the clipping portion 240 is released from the receiving portion 230.
Furthermore, even the panels 220 of the same size could have different thickness h, and/or could have different first distance d (i.e. between the panel 220 and the inner wall 212 of FIG. 1B). In the practical application, if the panel thickness h varies (and an overall width of the panel along the x-direction not being changed), the same clipping portion 240 can be selected for fixing the panel by inserting the adjusting component 244 (whose the thickness is corresponding to the first distance d) into the space between the panel 220 and the inner wall 212 until the fixing plane 246 contacts the bottom surface of the panel 220. After complete insertion, the hooking component 242 of the clipping portion 240 is engaged with the positioning component 232 of the receiving portion 230. Therefore, the panel-fixing device of the invention is adjustable at different heights on the casing 210 for fixing the panels with different thickness h. If the size of the panel 220 varies (i.e., the overall width of the panel 220 in the x-direction varies), the first distance d between the panel 220 and the inner wall 212 will be changed (i.e. shortened or widened). Several clipping portions 240 having different thicknesses of the adjusting components 244 could be designed based on different first distance d for filling the different gaps between the panel 220 and casing 210. According to the present invention, whether or not the panel thickness h or the first distance d between the panel 220 and inner wall 212 varies, it is not necessary to redesign a new casing 210 for fixing the panel.
After selecting the proper thickness of the adjusting component 244 in accordance with the first distance d between the panel 220 and the inner wall 212, the setup can be fine adjusted through different engaged position of the clipping portion 240. According to the descriptions above, after the adequate clipping portion 240 is selected, the first distance d can be filled up by the adjusting component 244 with corresponding thickness. Besides, the clipping portion 240 can also be adjusted by positioning the clipping portion 240 in different engaged positions. Please refer to FIG. 4A and FIG. 4B. FIG. 4A shows a diagram of the clipping portion 240 positioned in the first engaged position of the preferred embodiment according to the invention. FIG. 4B shows a diagram of the clipping portion 240 positioned in the second engaged position of the preferred embodiment according to the invention. In this preferred embodiment, several grooves 238 are vertically disposed on the outsides of the first wall 234 and the second wall 236. The clipping portion 240 further includes several projecting ribs 248. When the clipping portion 240 is engaged with the receiving portion 230, the clipping portion 240 is selectively wedged with one or more grooves 238 through one or more projecting ribs 248 at the first engaged position R1 or the second engaged position R2.
Refer to FIG. 1B, FIG. 4A and FIG. 4B. When the thickness of the adjusting component 244 is less than the first distance d (for example, the overall width of the panel 220 along x-direction is too small, and the adjusting component 244 is not thick enough to fill the space denoted as first distance d of FIG. 1B), the clipping portion 240 could be engaged with the receiving portion 230 in the first engaged position R1. As shown in FIG. 4A, when the clipping portion 240 is engaged with the receiving portion 230 in the first engaged position R1, the adjusting component 244 positioned in first space sp1 is more far away from the second space sp2 and able to press against the side wall of the panel 220. On the contrary, when the thickness of the adjusting component 244 is larger than the first distance d (for example, the overall width of the panel 220 along x-direction is too large), the clipping portion 240 could be engaged with the receiving portion 230 in the second engaged position R2. As shown in FIG. 4B, when the clipping portion 240 is engaged with the receiving portion 230 in the second engaged position R2, the adjusting component 244 in the first space sp1 is closer to the second space sp2 and able to press against the side wall of the panel 220. Thus, when the first distance d between the panel 220 and inner side 212 is different from the thickness of the adjusting component 244 of the clipping portion 240, the positions of the clipping portion 240 along the x-direction could also be adjusted by changing the engaged positions (ex: choosing R1 or R2) of the clipping portion 240 through designs of the projecting ribs 248 and the grooves 238.
According the panel-fixing device and the electronic device applied with the same disclosed in the above embodiment of the invention, the clipping portion is adjustably engaged with the receiving portion. The panels with different thicknesses could be fixed to the same casing by adjusting the clipping depth of the clipping portion. Also, the panels with different sizes could be fixed to the same casing by selecting the adjusting component with an adequate thickness for filling up the empty space between the panel and the casing, or by changing the engaged positions of the clipping portion 240 and the receiving portion 230. Thus, the panel-fixing device of the present invention can save the assembly time, simplify the manufacturing process (i.e. without fabricating different casing for those panels), and decrease the production cost (ex: a casing could be commonly used for fitting the panels having slightly different dimensions due to the novel panel-fixing device). Of course, it is to be understood that the numbers of the panel-fixing device used for stably fixing a panel to its casing can be varied according to the practical applications, and the invention is not limited to only one panel-fixing device.
While the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
