DETAILED DESCRIPTION
In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.
FIG. 1 is a perspective view of an electronic device according to the first embodiment of the disclosure; FIG. 2 is a perspective view of the electronic device in the close mode according to the first embodiment of the disclosure. As seen in FIGS. 1 and 2, an electronic device 10 comprises an input module 100, a connection assembly 200 and a display module 300.
The input module 100 has a recess structure 110. In this embodiment, the recess structure 110 is a recessed area a surface of the input module 100, and this recess structure 110 is inside the contour of this surface. As a result, the silhouette of the lateral sides of the electronic device 10 can remain smooth.
The connection assembly 200 comprises a link member 210 and a support plate 220. The link member 210 has a first end 211 and a second end 212. The first end 211 is pivotally disposed on one side of the input module 100. The support plate 220 has a first edge 221 and a second edge 222 that are opposite to each other. The first edge 221 is pivotally disposed on the second end 212, while the display module 300 is pivotally disposed on the second edge 222. In other words, the link member 210 is a hinge, the support plate 220 and the input module 100 are pivoted on two different axles of the link member 210, respectively.
In the electronic device 10 of this embodiment, the first end 211 of the link member 210 is pivotally disposed on the one side of the input module 110; the second end 212 is pivotally disposed on the first edge 221 of the support plate 220; the second edge 222 of the support plate is pivotally disposed on the display module 300. Therefore, this device becomes a double-cantilever type electronic device.
Referring to FIGS. 3A to 3D, FIGS. 3A to 3D are sectional views of the electronic device 10. FIG. 3A shows the display module 300, in a close mode, covers the input module 100. The input module 100 has the recess structure 110 and an input surface 140. The support plate 220 has an upper surface 227 and a lower surface 228. The upper surface 227 is farther away from the input module 100 than the lower surface 228. The display module 300 has a display surface 310 and a back surface 320 opposite to each other. In this embodiment, the display module 300 is a monitor with a touch screen.
When the display module 300 is in the close mode, it is disposed between the support plate 220 and the input module 100. Additionally, the back surface 320 of the display module 300 is attached to the lower surface 228 of the support plate 220, and the display surface 310 of the display module 300 is closer to the input module 100. When the users want to change the operational mode of the electronic device 10, they can rotate the display module 300 towards a direction away from the input module 100 (as seen in FIG. 3B). In this way, the users can operate this device as a normal laptop and they can even adjust the angle and the height of the display module 300.
When the users want to use the electronic device 10 in a tablet mode, they can flip the display module 300 to make the back surface 320 of the display module 300 be attached to the upper surface 227 of the support plate 220, as shown in FIG. 3C. Then, the display module 300 and the support plate 200 is moved closer to the input module, and eventually the back surface 320 of the display module 300 is attached to the input module 100. The support plate 220, meanwhile, is located the recess structure 110. Thereby, in the tablet mode, the display module 300 can be attached to the input module 100 smoothly and there is almost no gap between them (as shown in FIG. 4). In other words, the display module 300 is precisely fitted in the recess structure 110.
In one embodiment, the input module 100 further has an accommodating groove 190 located near one side of the link member 210. When the electronic device 10 is in the tablet mode, the second end 212 of the link member 210 is located in the accommodating groove 190.
FIG. 5 is a perspective view of the electronic device in the special usage mode according to the first embodiment of the disclosure. As seen in FIG. 5, in the special usage mode, an angle is formed between the back surface 320 and the input module 100 and this angle is less than 180 degrees.
FIG. 6A is a perspective view of an electronic device according to the second embodiment of the disclosure; FIG. 6B is a sectional view of the electronic device according to the second embodiment of the disclosure; FIG. 6C is a sectional view of the electronic device according to the second embodiment of the disclosure. As seen in FIGS. 6A to 6C, different from the first embodiment, in the second embodiment, the recess structure 110 further has a plate body 130 and two elastic members 120. One end of the elastic member 120 is disposed on one side of the plate body 130. Due to the arrangement of the elastic member 120, the plate body 130 can have a hold-up position and a sinking position. Moreover, in this embodiment, when the plate body 130 is at the hold-up position (that is, when the elastic members 120 are not compressed), the input surface 140 and the surface of the plate body 130 away from the two elastic member 120 are coplanar. Thereby, the surface of the input module 100 is leveled for being sleek. In this embodiments, the elastic members are springs, but the disclosure is not limited thereto. Also noteworthy is that, in other embodiments, the number of the elastic member 120 can be one or more than one.
In this embodiment, when the electronic device 10 is in the tablet mode, the display module 300 is stacked on the support plate 220 and the back surface 320 of the display module 300 is attached to the upper surface 227 of the support plate 220. The lower surface 228 of the support plate 220, meanwhile, pushes the plate body 130 and then makes it move from the hold-up position to the sinking position. The two elastic members 120, at this point, store elastic potential energy. When the users rotate the display module 300 to a direction away from the input module 100 so that the display module 300 is no longer in the tablet mode (as seen in FIG. 6B), the two elastic members release the elastic potential energy. The plate body 130, therefore, moves from the sinking position to the hold-up position. Thereby, the surface of the input module 100 is kept to be flat. Because of the design of the recess structure 110, the display module 300 in the tablet mode can be attached to the input module 100 evenly.
Furthermore, the support plate of the electronic device of the disclosure can have different structural designs. These designs are shown in FIG. 7 to FIG. 9.
To sum up, in the electronic device illustrated in the above-mentioned embodiments, the first end of the link member is pivotally disposed on one side of the input module and the first edge of the support plate is pivotally disposed on the second end of the link member. Additionally, the display module is pivotally disposed on the second edge of the support plate and the recess structure is disposed. Thereby, when the display module is working in the tablet mode, it levels with the input module smoothly. Thus, this avoids the damages of the conventional electronic device in the case that the users push the display module towards the input module because they want to eliminate the gap between them.
