Description

Form and structure of terminal for convenience of mobile application {The Cellular Phone Formation for Convenient mobile application use}

The form of the mobile phone is infinite, ranging from the general flip type (Fig. 1-1) to the folding type (Motorola development) (Fig. 1-2), and the 180 degree rotation type (Motorola development) (Fig. 1-3). It has evolved. All of them have their advantages and disadvantages, and the difference is that consumers buy the type of telephone they want. At present, the most popular and most common type of mobile phone is a folder with an external LCD or organic EL display window. This type of mobile phone is constrained by the interface when using the wireless Internet and other applications that are currently widely used. . To complement this, PDA phones (Figs. 1-4) and mobile phones in the form of rotating the display portion to interface with a touch screen like a PDA (aka Swivel type) (Figs. 1-5) are also on the market. .

Mobile phones have already become more ubiquitous than phones. This requires not only wireless Internet but also other entertainment and game player functions. To this end, problems such as fast information input method and effective key placement have been raised.

The present invention is a proposal of a mobile phone shaping structure that is suitable for such a trend and can provide consumers with aesthetic satisfaction and ease of use at the same time.

The technical problem to be achieved by the present invention can be summarized into about three.

Provides ease of use of applications in mobile phones such as wireless Internet and effective placement of other devices.

The use of one display panel allows the user to retrieve important information even when the phone is not in use.

Provides users with aesthetic satisfaction.

Figure 7, variant process

The present invention is largely divided into four parts.

A main body unit (FIG. 3-1) integrating a function control as a main cellular phone, a part of a talker (SIP), and a secondary input device (2IPA);

A camera hinge unit (FIG. 3-2) combining a camera (CCD) and a hinge (HG);

A display unit rotatable with a display panel DP and a receiver SOP (Fig. 3-3);

Secondary input pad to install additional license plate (NP) and secondary input device (2IPB) that can not afford in the main body (Fig. 3-4)

At first glance, the features of the present invention resemble Motorola's 180-degree rotary cell phone (FIGS. 1-3), which is the final element of the composition [secondary input pad] (FIG. 3-4) and the camera and Hinge It is in the branch (Figure 3-2). The other part may be the same as the 180-degree rotation type, but by installing the [secondary input pad], the expandability of the device shows a marked difference. The [secondary input pad] can be installed any necessary input device. Possible input devices include a split keypad (Fig. 4-1), a joy pad (Fig. 4-2), a touch pad (Fig. 4-3), and the like.

The secondary input pads 3-4 are made up of license plates, swiveling joints, and secondary input pad portions. That is, generally, when answering a call, only the display unit is rotated, and when the secondary cladding unit is needed, the secondary input pad is slightly rotated, and the pad unit is rotated once again as shown in the modification process of FIGS. All these modifications are visualized in FIG.

In order to realize this, and to implement a systematic movement, it requires a unique structured hinge. The hinge used in the present invention takes the form of a double hinge. The position of the hinge is specified in FIG. This unique type of hinge is configured in the form of [display unit: (main unit: secondary input pad)]. In other words, when rotating the display. The main unit and the secondary input pad rotate in an integrated system, and an independent hinge and a rotation axis are provided between the main body and the secondary input pad.It can be used like a normal mobile phone, but only when another input device is needed, You can change the shape of the device by the movement of. For more structured operation, it would be wise to impart the same angular movement to the body portion as that of the secondary input pad. In other words, when the secondary input pad moves 60 degrees clockwise, the main body also moves 60 degrees counterclockwise to prevent chaotic mechanical motion. In this way, the chaotic movement of the three components can be organized.

Two proposals for the shape of the hinge to achieve this are specified in FIGS. 5 and 6. In the first case (Fig. 5), it takes a fairly stable form with some angular velocity differences. The basic principle of this hinge is that the secondary input pad rotation axis (2IPBT) rotates the rubber headphone shaft (RTP) to rotate the main body rotation (MT) axis at the same linear speed. When the friction coefficient is set to 100% (by gear introduction, etc.), the linear speed, that is, the linear distance that the secondary input pad rotation axis (2IPBT) moves and the main body rotation axis (MT) move equal to each other. At this time, since the straight distance is the same but the radius is different, the size of the moving angle is different and the angular velocity is also different. And, the smaller the difference between the inner radius of the secondary input pad rotational axis (takes a centered cylindrical shape, 2IPBT) and the radius of the main body rotational axis, the smaller the difference in angular velocity. Thus, when adopting this hinge structure, it is inconvenient to reduce the size of the rubber rotating shaft (possible to replace the gear) therebetween.

Thus again proposed is a hinge structure of the type specified in FIG. In this proposal, both the secondary input pad rotation axis (2IPBT) and the main body rotation axis (MT) have a hollow cylindrical shape. When adopting this hinge, the angular velocities of the two parts are exactly the same. When the coefficient of friction is specified as 100%, the angular velocity up and down and the linear velocity (for example, gear introduction) coincide.

By spreading out as above, if a secondary input device such as a keypad or a joy pad is obtained, the secondary input device is not only used for a mobile phone of the present invention, but a device such as a PDA, which is generally difficult to install a keypad and a joy pad. The keypad can be used as a joypad. This mechanism is omitted because it is the same as a keypad for a conventional PDA.

In addition to the features listed above, scalability will be apparent to anyone with knowledge of the technology.

1. Video call is possible even in the closed state (Fig. 2-1).

2. Extended input device (Fig. 2-3) allows for more convenient input.

3. The input device is expanded in the same state as a normal mobile phone, so there is no inconvenience for the unfamiliar people.

4. Since the input device is folded, the size of the mobile phone is significantly reduced compared to that of other structures.

5. In addition to the keypad, other input devices can be installed instead. (User can not install, but in production)

6. It can be used as an input device for other electronic devices (PDA, etc.).

7. Provide aesthetic satisfaction to the user.

Claims (5)

As described above and visualized in FIG. 2, it can be divided into two parts and three parts as necessary, and has a structure for smoothing not only number input but also general character input, game joypad command input, etc. Is mounted on a hinge outside the display, allowing video calls to be made in a closed state. By swiveling the secondary input pad described herein, the structure of the mobile phone can secure a wider input area (about 3 times as much as the existing mobile phone) while maintaining the size of the existing mobile phone. shape The structure and form of the hinge for the present invention, characterized in that by connecting the secondary input pad and the main body in this specification, each move by the same angle in different directions. (Specified in Figure 6) As shown in [Hinge Position] of FIG. 5, three components: the display unit, the secondary input pad, and the main body portion, when unfolded, are characterized in that all three components can be freely rotated about an axis thereof. Form and structure of mobile phones. (Specified throughout drawing) As specified in this specification, not only functions as a mobile phone, but also a form and structure of a mobile phone, which can be used as an input device of another electronic device (PDA, etc.) instead.
