## Background
RELATED APPLICATIONS
The present application is based on, and claims priority from, Taiwan Application Serial Number 94140352, filed Nov. 16, 2005, the disclosure of which is hereby incorporated by reference herein in its entirety.
FIELD OF THE INVENTION
The present invention is related to a rotating module for a display, and more particularly to a rotating module for a display installed in a portable device.
BACKGROUND OF THE INVENTION
Many advantages exist of a liquid crystal display (LCD), such as high display quality, small volume, low weight, low voltage driving, and low power consumption. Therefore, LCDs have been extensively used in various portable electrical devices, such as mobile phones and notebooks.
Typically, the LCD is embedded in a foldable cover of a folding-type mobile phone. When using this type of mobile phone for a call, the cover is first opened to expose the LCD. A rotating mechanism is installed between the cover and the base of the mobile phone for adjusting the opening angle of the cover to change the LCD view angle. However, the LCD is rotated around a fixed axis so the distance between the LCD and the base is fixed. Therefore, the LCD position has to be considered when using the keyboard. For example, the control key of a typical foldable mobile phone is located close to the LCD such that using the control key obstructs the user from viewing the LCD.
Therefore, it is the goal for a designer to create a mobile phone with an LCD that can be freely adjusted by a user for changing its view angle and location.
SUMMARY OF THE INVENTION
The purpose of the present invention is to provide a rotating module that permits the display to rotate around two different axes for adjusting the view angle.
Another purpose of the present invention is to provide a rotating module for a user to freely adjust the view angle of the display.
A further purpose of the present invention is to provide a rotating module that parallelly arranges the display module and the keyboard module.
According to the foregoing purposes, the embodiment of the present invention provides a rotating module used in a portable device with a cover and a base. The cover has a coupling part for coupling with the base module. The coupling parts is separable from the base module. The rotating module is fixed in the base for connecting with the cover. The rotating module includes a first rotating part and a second rotating part connected together. The first rotating part can provide the cover to rotate around the first axis. The second rotating part fixed in the base can provide the cover to rotate around the second axis. The first rotating part couples with the cover. The cover coupling with the base can rotate around the first axis. When the first coupling part of the cover is connected to the second coupling part of the base, the cover can rotate around the first axis to cover the base. When the coupling part of the cover is separated from the base, the cover couples with the base through the rotating module, and the second rotating part can rotate the cover around the second axis. The included angle between the first axis and the second axis may be 90 degrees or other angle based on the device design.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The following describes the preferred embodiment of the present invention.
FIG. 1 is an exploded view of a portable device with a rotating module according to the preferred embodiment of the present invention. The rotating module is used in a portable device 100 with a foldable cover, wherein the portable device 100 includes a cover 102, a base module 104, and a rotating module 106. A display (not shown in this figure) is embedded in the cover 102. The first end 108a of the first coupling part 108 in the cover 102 is connected to the second coupling part 110 of the base module 104 through the rotating module 106. The second end 108b of the first coupling part 108 is connected to the third coupling part 112 of the base module 104. A tenon is embedded in the third coupling part 112 of the base module 104. A user can control the tenon to release the second end 108b of the first coupling part 108 from the third coupling part 112. In this case, the cover 102 and the base module are connected together only through the rotating module 106.
The rotating module 106 includes first and second rotating parts 105 and 107. The first rotating part 105 can rotate the cover 102 around the X-axis from 0 to 180 degrees. The second rotating part 107 can rotate the cover 102 around the Y-axis form 0 to 180 degrees. The first rotating part 105 is fixed in the first end 108a of the first coupling part 108. The second rotating part 107 is fixed, such as by screws, in the second coupling part 110. When combined to form the portable device 100, the first rotating part 105 is coupled to the second rotating part 107 to combine the cover 102 and the base module 104.
FIG. 2 is an exploded view of the rotating module according to the preferred embodiment of the present invention, in which the rotating module 106 includes a first rotating part 105 and a second rotating part 107. The second rotating part 107 includes a rotating means 1071, a rotating base 1072, a fixed piece 1073 and a fixed axis 1074. The fixed axis 1074 passes through the hole in the center of the fixed piece 1073 to fix the rotating means 1071 in the rotating base 1072. There are two fixed holes 1072a and 1072b in the base 1072. The screws 114 insert through the holes to fix the base 1072 in the second coupling part 110, as shown in FIG. 1. Such fixing ensures that the base 1072 does not move when the rotating means 1071 is rotated. The first rotating part 105 also includes a rotating means 1051 and a fixed axis 1052 that is fixed in the rotating means 1071 such as by a hole (not shown in this figure) formed in the rotating means 1071. Then, the fixed axis 1052 is fixed in the hole. Such structure ensures that the second rotating part 107 is not influenced by the rotating means 1051 when it rotates around the fixed axis 1052.
FIG. 3 illustrates an assembly of the rotating module according to the preferred embodiment of the present invention. The first rotating part 105 through the fixed axis 1052 is connected to the second rotating part 107. The rotating means 1051 of the first rotating part 105 is fixed in the first end 108a of the first coupling part 108 as shown in FIG. 1. The rotating base 1072 of the second rotating part 107 is fixed in the second coupling part 110. The cover 102 is connected with the base module 104 through the coupling of the first rotating part 105 and the second rotating part 107.
FIGS. 4a to 4d illustrate operation of a portable device by the rotating module of the present invention. Reference is also made to FIGS. 5a to 5d which specifically illustrate the corresponding operation of the rotating module 106 through the steps shown in FIG. 4. In FIG. 4a, a foldable cover 102 of a mobile phone is closed to the base module 104. In this case, the rotating module 106 is in a normal state as shown in FIG. 5a. 
In FIG. 4b, the foldable cover 102 is lifted by a user along the direction of the arrow 120. In this case, the first rotating part 105 of the rotating module 106 is rotated 180 degrees clockwise around the X-axis to lift the cover 102 as shown in FIG. 5b. In FIG. 4c, the second end 108b of the first coupling part 108 is released from the third coupling part 112. The cover 102 is rotated along the direction of the arrow 121. In this case, the second rotating part 107 of the rotating module 106 is rotated clockwise around the Y-axis as shown in FIG. 5c. In FIG. 4d, the cover 102 is rotated to the position parallel to the base module 104. In this case, the second rotating part 107 of the rotating module 106 is rotated 180 degrees clockwise around the Y-axis as shown in FIG. 5d. 
Reference is made to FIG. 4d again. The display embedded in the cover 102 can be rotated to be parallel with the keyboard 1041 of the base module 104. In this case, the keyboard 1041 is under the display 1021. The relationship between the keyboard 1041 and the display 1021 is similar to a portable notebook. Therefore, a user can use the wide display to show certain material or to type as a portable notebook.
Accordingly, the rotating module of the present invention can adjust the display in two different directions. Therefore, it can completely adjust the display for not only the location but also the viewing angle. Moreover, the display can be rotated to be parallel with the keyboard. Such structure may provide a wide display to show certain material and to type as a portable notebook.
As is understood by a person skilled in the art, the foregoing descriptions of the preferred embodiment of the present invention are an illustration of the present invention rather than a limitation thereof. Various modifications and similar arrangements are included within the spirit and scope of the appended claims. The scope of the claims should be accorded to the broadest interpretation so as to encompass all such modifications and similar structures. While a preferred embodiment of the invention has been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
