The following is a detailed description of the best presently contemplated modes of carrying out the invention. This description is not to be taken in a limiting sense, and is made merely for the purpose of illustrating general principles of embodiments of the invention. The scope of the invention is best defined by the appended claims.
Reference is made to FIGS. 1-2, which are perspective views of a portable electronic product with a Qwerty keyboard of the first embodiment in a closed condition and a swiveled condition according to the present invention. The present invention provides a portable electronic product with a Qwerty keyboard 1, which includes a housing 10, a display 20 and a Qwerty keyboard 30. The display 20 is disposed on a top surface of the housing 10. The Qwerty keyboard 30 is assembled in the housing 10.
In this first embodiment, the portable electronic product 1 has a rectangular shape, and also has a pair of parallel lengthwise sides 11, 12 and a pair of lateral sides 13, 14. However, the present is not limited in such a form, for example, the portable electronic product can be square shaped. The portable electronic product 1 of this embodiment has the communication functions of a mobile phone, and a top surface 16 of the portable electronic product 1 has a speaker 163 and a receiver 164 and is equipped with function keys 161, 162.
The display 20 has a side 22 that is connected pivotably to one of the lengthwise side 12. As shown in FIG. 2, the Qwerty keyboard 30 has letters (or symbols) 31 that are printed thereon and arranged perpendicular to a pivotal side 12 of the housing 10. In this embodiment the present invention designates the side 12 as the pivot side. As shown in FIG. 1, the present invention provides a pivotal axle 24 between the display 20 and the housing 10, so that the display 20 can be swiveled as shown in FIG. 2. In addition, having such a structure makes it easy to arrange the connecting cable between the display 20 and the housing 10.
Reference is made to FIG. 2. The Qwerty keyboard 30 is mounted in the housing 10 and exposed to a bottom surface 17 of the housing 10. The Qwerty keyboard 30 has an exposed surface that is lower than the bottom surface 17 of the housing 10. In this embodiment, the housing 10 is concaved with a depression 172 from the bottom surface 17. The Qwerty keyboard 30 is disposed in the depression 172, thereby such a structure prevents the keyboard 30 from rubbing against a table when the portable electronic product 1 is disposed on a table.
Through the above-mentioned structure, the display 20 of the present invention is pivotably mounted on the housing 10 along the side 12 which is a pivotal axle (not shown in the Figure). When the user does not need to input information, the bottom surface of the display 20 is close to the top surface of the housing 10. When the user needs to input information, the display 20 can be swiveled to face the user and the Qwerty keyboard 30 also simultaneously faces the user.
It is not so frequently for user to input data to the portable electronic product via a keyboard. Nevertheless, the portable electronic product of prior art is usually limited in that it lacks a Qwerty keyboard for inputting data, when user needs to input data. One of the characteristics of the present invention is that, the display 20 of the portable electronic product 1 is usually close to the top surface of the housing 10 when the portable electronic product 1 is being used in its most common situations, such as when it is functioning as a mobile phone. The display 20 can be swiveled outside along the pivotal axle to face the user, so that the display 20 and the Qwerty keyboard 30 can face to the user simultaneously when the user needs to input data. As shown in FIG. 2, there is an included angle between the display 20 and the housing 10. A preferred range of the included angle is between 0 degree to 270 degrees, so that the user can adjust the viewing angle of the display 20. The pivotal axle structure provides a predetermined friction force for fixing the display 20 relative to the housing 10, so that the display 20 of the present invention can be easily fixed at any included angle relative to the housing 10.
In this embodiment, the display 20 has a pair of sides 21, 22. The side 22 pivotably mounted on the housing 10 is shorter than the lengthwise side 12 of the housing 10. The housing 10 is formed with a receiving space 15 (as shown in FIG. 1) for receiving the display 20, and the display 20 has a top surface 23 that is aligned with a top surface 16 of the housing 10. The advantage of such structure is that the pivotal axle 24 can be smaller and shorter, and the total thickness of the portable electronic product 1 can be thinner.
As shown in FIG. 2, the Qwerty keyboard 30 is formed with letters 31 thereon and the letters 31 are arranged to perpendicular to the side 12 between the display 20 and the housing 10. Moreover, the Qwerty keyboard 30 fully utilizes the space at the bottom surface 17 of the portable electronic product 1 that is rarely used in prior art. In the present invention, the Qwerty keyboard 30 is disposed at the bottom surface 17 of the portable electronic product 1 and usually faces away from the display 20 when the portable electronic product 1 is being used in its most common situations, such as when it is functioning as a mobile phone. When the user needs to input data, only the display 20 needs to be swiveled along with the pivotal axle 24 (shown in FIG. 2) and then both the display 20 and the Qwerty keyboard 30 can face to the user simultaneously. The user can input data conveniently via the Qwerty keyboard 30 when operating the portable electronic product.
Reference is made to FIG. 3, which is a structure block diagram of a portable electronic product with a Qwerty keyboard according to the present invention. The housing 10 has a circuit board 18 mounted therein. The circuit board 18 has a CPU 182 and a display control unit 184 for controlling the displaying direction of the display 20. A sensor 40 is disposed between the housing 10 and the display 20. When the display 20 is swiveled, the sensor 40 transmits an actuating signal to the CPU 182 for actuating the display control unit 184; Therefore, the displaying direction of the display 20 can be changed. The sensor 40 can be a mechanical actuating switch or a magnetic induction switch, etc.
It should be noted that the above-mentioned is only one preferred embodiment according to the present invention, and any software or mechanical designing can achieve the transformation of the displaying direction of the display 20, or a button can be provided for the user to adjust the displaying direction of the display 20 is not limited by this example.
The Qwerty keyboard 30 of the present invention could be an electronic-type touch keyboard or a mechanical-type keyboard. For operating conveniently in an environment lacking light, the portable electronic product 1 has a backlight source 32 electrically connected to the circuit board 18. The backlight source 32 in FIG. 3 is shown as a block, but in practice it can include an LED light source, a diffusion sheet, a light guiding plate (LGP) or a reflection sheet. When the Qwerty keyboard 30 is not in use, the backlight source 32 is turned off to reduce power consumption.
In the present invention, a backlight switch 186 is disposed between the backlight source 32 and the CPU 182. When the display 20 is turned outward, the actuating signal transmitted from the sensor 40 can further conduct the backlight switch 186 through the CPU 182, thereby automatically turning on the backlight source 32.
In the present invention, the Qwerty keyboard 30 can be designed in a hidden way at the bottom surface 17 of the housing 10. Reference is made to FIG. 4, which is a cross-sectional view of a hidden-type keyboard according to the present invention. In this embodiment, an electronic-type touch keyboard 30 is shown to illustrate how the keyboard is disposed at the bottom surface 17 of the housing 10 in a hidden way. The hidden electronic-type touch keyboard 30 includes the backlight source 32, a protective layer 34, and a touch panel 36 disposed under the protective layer 34.

When the backlight source 32 is turned off, the Qwerty keyboard 30 is shielded by the protective layer 34 and is hidden under the protective layer 34. The user cannot see the letters 31 or pattern of the Qwerty keyboard 30. This means the user cannot see the keyboard 30 in this situation. When the backlight source 32 is turned on, the light passes through the touch panel 36 and the protective layer 34. Therefore, the letters 31 or the pattern of the Qwerty keyboard 30 can appear outside. In other words, the user can see the Qwerty keyboard 30. According to the above-mentioned design, the Qwerty keyboard 30 is ordinarily hidden, but it can appear when the user needs to input data.
Reference is made to FIG. 5, which is a cross-sectional view of a hidden-type keyboard of another embodiment according to the present invention. The keyboard 30 in this embodiment is a mechanical-type keyboard. The semiopaque protective layer 34 covers a mechanical key layer 36 All keys 362 of the mechanical key layer 36 can be made of light-pervious material, so that light can pass through the keys 362 and the protective layer 34. In this embodiment, letters 31 can be printed on the keys 362 of the mechanical key layer 36′ on the inner side of the protective layer 34. When the letters 31 are printed on the inner side of the protective layer 34, the keyboard 30 can be more easily manufactured.
For avoiding unintended inputting of data to the keyboard 30, the portable electronic product 1 with a Qwerty keyboard of the present invention can lock the keyboard 30 via software/firmware and functional shortcut keys.
