DETAILED DESCRIPTION OF THE INVENTION

While the invention has been described in connection with various aspects, it will be understood that the invention is capable of further modifications. This application is intended to cover any variations, uses or adaptation of the invention following, in general, the principles of the invention, and including such departures from the present disclosure as come within the known and customary practice within the art to which the invention pertains.

In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as “top,” “bottom,” “front,” “back,” etc., is used with reference to the orientation of the Figure(s) being described. The components of the present invention can be positioned in a number of different orientations. As such, the directional terminology is used for purposes of illustration and is in no way limiting.

Referring to FIG. 1A, an embodiment of an electronic device can be selectively used as a tablet computer/touch control computer or a laptop computer. The electronic device primarily comprises a main body 10 an input unit 20, and a display unit 30. In this embodiment, the main body 10 is pivotally connected to the display unit 30, wherein a CPU and a main board is disposed in the main body 10. A keyboard or touchpad may be disposed on the surface of the input unit 20, and the input unit 20 is connected with the main body 10 in a detachable manner.

In an exemplary embodiment, if the users would like to use the electronic device as a tablet computer/touch control computer, the input unit 20 can be detached from the main body 10. Alternatively, if the users would like to use the electronic device as a laptop computer, the input unit 20 can be joined to the main body 10 for convenient usage. In this embodiment, the display unit 30 has a flat touch control display and electrically connects to the main body 10, wherein the display unit 30 is rotatable around a rotation axis C with respect to the main body 10.

It should be noted that when the input unit 20 is detached from the main body 10, as shown in FIG. 1A, the display unit 30 and the main body 10 may have an inclined angle therebetween, so that users can conveniently see the screen 31 on the display unit 30 and directly input data or click through the screen 31. Additionally, the display unit 30 can be folded to the main body 10 by a user rotating the display unit 30 relative to the main body 10 toward the rear side thereof around the rotation axis C, as the arrow indicates in FIG. 1A. Thus, the main body 10 and the input unit 20 can form a tablet structure, as a tablet computer, for users to input data directly or click through the screen 31.

Moreover, if a user would like to incorporate the main body 10, the input unit 20, and the display unit 30 as a laptop computer, the input unit 20 can be joined to the main body 10 as shown in FIG. 1B. Here, the display unit 30 can be rotated around the rotation axis C and adjusted to an appropriate angle with respect to the main body 10, as indicated by the arrow in FIG. 1B. This way, the user can input data or click through the keyboard or touchpad on the input unit 20 to facilitate flexible and convenient usage.

In FIG. 1A, the main body 10 in this embodiment has at least a recess 11, and the input unit 20 has at least a protruding portion 21 corresponding to the recess 11. When the input unit 20 is assembled to the main body 10, the protruding portion 21 is joined in the recess 11, such that the input unit 20 and the main body 10 are firmly secured to each other. Furthermore, to achieve rapid connection between the input unit 20 and the main body 10, the main body 10 has a first magnetic element M1 therein, and the input unit 20 has a second magnetic element M2 therein. When the input unit 20 is close to the main body 10, they can be mutually aligned and positioned by magnetic attraction between the first and second magnetic elements M1 and M2. Thus, the protruding portion 21 can be rapidly joined to the recess to improve the efficiency of assembly.

Referring to FIG. 2A, the main body 10 has two protrusions 101 and 102. When the main body 10 is placed on a surface S of an object (such as a table), protrusions 101 and 102 contact the surface S, such that the main body 10 can be prevented from sliding due to the friction between the surface S and the protrusions 101 and 102.

The input unit 20 has a support 201 and a pad 202 on the bottom side thereof. When the input unit 20 is detached from the main body 10 and placed on the surface S, as shown in FIG. 2A, the support 201 and the pad 202 contact the surface S to stably support the input unit 20. It should be noted that the protruding lengths of the support 201 and the pad 202 are different. When the input unit 20 is joined with the main body 10, the pad 202 is suspended and spaced apart from the surface S. The detailed configuration will be described below.

Referring to FIGS. 2B and 3, FIG. 3 is an enlarged view of the portion A in FIG. 2B. When the input unit 20 is joined with the main body 10, as in the state shown in FIG. 2B, the pad 202 of the input unit 20 is distant from the main body 10 by a first distance D1, and the support 201 is distant from the main body 10 by a second distance D2. In FIGS. 2B and 3, the support 201 on the bottom side of the input unit 20 has a first protruding length H1, and the pad 202 on the bottom side of the input unit 20 has a second protruding length H2, wherein the first protruding length H1 exceeds the second protruding length H2. Moreover, the protrusions 101 and 102 on the bottom side of the main body 10 have a third protruding length H3 which substantially equals the first protruding length H1 and exceeds the second protruding length H2.

FIG. 3 illustrates the protruding portion 21 on the lateral side of the input unit 20 when joined and fixed to the recess 11 on the main body 10, such that the pad 202 that is shorter than the support 201 is lifted and spaced apart from the surface S by a distance h, so as to reduce the friction between the surface S (such as a table) and the pad 202 of the input unit 20. Since interference of the friction between the surface S and the pad 202 is absent, assembly between the main body 10 and the input unit 20 can be much easier for users. Additionally, rapid positioning and connection between the first and second magnetic elements M1 and M2 can also be achieved, thereby reducing the assembly time and improving the efficiency of usage. In some embodiments, the support 201, the pad 202, and the protrusions 101 and 102 may have a low-friction coating such as (Polytetrafluoroethene, PTFE), so as to reduce friction when in contact with the surface S.

In summary, the invention provides an electronic device, wherein a pad is disposed on the bottom side of the input unit. Thus, when the input unit is separated from the main body, the pad can contact an object surface (such as a table) for supporting the input unit. Additionally, when the input unit is joined with the main body, the pad is suspended and spaced apart from the surface by a distance, such that the friction between the pad and the object surface can be reduced. Hence, easy assembly of the electronic device can be achieved without interference of friction, so as to facilitate convenient usage.

While the invention has been described by way of example and in terms of 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 (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation to encompass all such modifications and similar arrangements.
