BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a detachable touch structure of a portable electronic device; more particularly, the present invention relates to a detachable touch structure that can be transformed into a mouse form.
2. Description of the Related Art
In general, a portable computer such as a notebook PC or a minicomputer is equipped with a touch panel to perform functions of a mouse commonly used with a desktop PC and to facilitate cursor control on a user interface. However, some people are accustomed to using mice and find it inconvenient to use touch panels; therefore, they will use externally and electrically connected mice to operate user interfaces even when their portable computers are provided with touch panels. As such, they have to carry mice along with portable computers and to sacrifice the compactness of portable computers. Besides, it is troublesome for users using wireless mice, because they have to pay attention to the power level of the wireless mice and to replace batteries/recharge the mice to keep the mice working.
Therefore, it is desirable to provide a device whose structure can be transformed to act as a touch panel or a mouse to eliminate the need for an additional mouse and to save space.

These and other objects and advantages of the present invention will become apparent from the following description of the accompanying drawings, which disclose several embodiments of the present invention. It is to be understood that the drawings are to be used for purposes of illustration only, and not as a definition of the invention.
The detachable touch structure of the present invention can be applied in portable electronic devices. In an embodiment of the present invention, the portable electronic device is a notebook PC; however, the portable electronic device can be a mini computer, a tablet PC or any other electronic devices having touch panels or modules.
Please refer to FIG. 1 and FIG. 2. FIG. 1 illustrates a schematic drawing of the detachable touch structure of the present invention in a mouse form. FIG. 2 illustrates a system block diagram of the detachable touch structure and the portable electronic device of the present invention.
As shown in FIG. 1, the detachable touch structure 1 of the present invention comprises a flexible board 10, a flexible touch panel 20, a control module 30, and a linkage element 40. The flexible board 10 acts as a major framework of the detachable touch structure 1; the flexible touch panel 20 is superimposedly disposed on the flexible board 10, the flexible touch panel 20 can be attached to the flexible board 10 by gluing to provide a touch function when the detachable touch structure 1 is in a tablet form. In the present embodiment, the elasticity of the materials of the flexible board 10 and the flexible touch panel 20 (such as rubber or flexible metals) allows the flexible board 10 and the flexible touch panel 20 to remain bended under normal operation condition to form the mouse form of the detachable touch structure 1 of the present invention shown in FIG. 1. Besides, the flexible touch panel 20 further comprises a thin film layer 21 attached to a surface of the flexible touch panel 20 for protecting the flexible touch panel 20 or keeping the flexible touch panel 20 from being stained. In this embodiment, the thin film layer 21 can be made of polyester or other like materials.
As shown in FIG. 1 and FIG. 2, the control module 30 is connected with the flexible board 10 by using a screw or gluing to fix it thereon. The control module 30 is electrically connected with the flexible touch panel 20 via electrical contacts for obtaining touch signals from the operation of the flexible touch panel 20.
The control module 30 comprises a signal transmission unit 31 and a battery unit 32 disposed therein. When the detachable touch structure 1 of the present invention is in a mouse form, it detaches from the body 81 of the portable electronic device 80 and uses the signal transmission unit 31 for transmitting signals between the detachable touch structure 1 and the portable electronic device 80 wirelessly; so the detachable touch structure 1 acts as a wireless mouse. In this embodiment, the signal transmission unit 31 can be a Bluetooth transmission unit or other devices capable of wireless transmission. The battery unit 32 supplies power to the detachable touch structure 1 when it is in the mouse form, and the battery unit 32 can be charged when the detachable touch structure 1 is electrically connected with the portable electronic device 80.
As shown in FIG. 1, the linkage element 40 is used for transforming and positioning the detachable touch structure 1 between the mouse form and the tablet form. The linkage element 40 comprises two positioning levers 41. The linkage element 40 has one end pivotally connected with the flexible board 10 and the other end movably connected with the control module 30 via each positioning lever 41. A displacement of the linkage element 40 can turn the flexible board 10 into a curved shape or can keep it flat, thereby switching the detachable touch structure 1 between the mouse form and the tablet form.
Please refer to FIG. 3, which illustrates a schematic drawing of the linkage element of the detachable touch structure of the present invention connected with the control module. As shown in FIG. 3, the control module 30 comprises two single path sliding slots 33 symmetrically disposed at each side of the control module 30 (only one side is shown in FIG. 3, and the single path sliding slot 33 of the other side is symmetrical to that shown in FIG. 3), the two positioning levers 41 of the linkage element 40 have column structures formed at their front ends respectively and provided for inserting into the corresponding single path sliding slots 33; therefore each of the positioning lever 41 can move along the single path sliding slots 33. Each of the single path sliding slots 33 comprises a fixing hole 34 located at one end of the single path sliding slot 33, the depth of the fixing hole 34 is deeper than the depth of the single path sliding slot 33 such that the column structure of the positioning lever 41 can be fastened with the fixing hole 34 after the positioning lever 41 moving to the fixing hole 34. At this time the detachable touch structure 1 of the present invention is in the mouse form. In the present embodiment, the single path sliding slot 33 is a straight slot, but it can be changed to other kind of slot to meet the requirement.
Furthermore, as shown in FIG. 1 and FIG. 2, the detachable touch structure 1 further comprises a plurality of keys 50, each key 50 has one end connected to the flexible board 10 and a space to keep the key 50 and the flexible board 10 separated. The control module 30 comprises a plurality of switches 35 disposed in the space and corresponded to the plurality of keys 50 respectively; therefore, when any key is pressed, a corresponding switch 35 is triggered to generate and send a control signal to the portable electronic device 1. In this embodiment, the present invention uses the plurality of keys 50 to correspond to a traditional mouse structure, but the present invention can also use any key 50 as a mouse wheel, or to extend the flexible touch panel 20 to include a touch key area for performing key functions; therefore, there can be many variations for the present invention.
