Description

Foldable mobile phone with sliding cover on the outside

The present invention relates to a mobile phone, and more particularly, the display is installed on the outer surface of the cover to allow the call reception and message confirmation without opening the cover and the display is mounted on the outer surface so that the cover can be easily opened by sliding. It relates to a clamshell mobile phone is a sliding cover opening and closing.

In general, mobile phones are widely used as wireless communication devices due to the development of electronic communication technology. Such mobile phones have been made smaller and smaller in size in the first bar type, and are recently manufactured in a smaller and lighter folder type, and the quality and function of a call are being improved. Hereinafter will be described with reference to the drawings showing such a folding cell phone conventionally used.

1 is a perspective view of a conventional general folding cellular phone. As shown, the folding cellular phone 1 is composed of a main body 2, a cover 3, and an antenna 4. The main body 2 is provided with a plurality of function buttons 2a on an upper surface thereof, and a talker 2b is formed below the function button 2a. Accordingly, the user delivers a message to the other party through the talker 2b. And the cover 3 which opens is made with the upper end of the said main body 2 as the rotating shaft 5 is provided. A display 3a is formed on the inner surface of the cover 3 so that letters and numbers can be recognized by the user, and a sign language portion 3b is positioned above the display 3a. Therefore, the message of the other party is transmitted through the receiver 3b, so that the user can recognize it. Then, a lamp (not shown) is installed above the outer surface of the cover 3 to notify the user by the light of the lamp when a call is received from the other party.

On the other hand, the antenna 4 is installed on the right rear side of the main body (2). The antenna 4 is inserted into the casing of the main body 2 in order to reduce the size of the wireless device, and has only a top end exposed to the outside of the main body 2. That is, in a cellular phone that communicates using wireless, it is impossible to transmit or receive a radio signal without the antenna 4, and therefore, installation of the antenna 4 is essential. Therefore, in order to achieve miniaturization of the cellular phone, the mobile phone is accommodated in the casing of the main body 2, and only the upper end portion of the antenna 4 protrudes outward. And, since the length of the antenna 4 is adjusted, if the transmission or reception is not well made, the antenna 4 inserted into the main body 2 is pulled out to extend the length so that the sensitivity of the transmission and reception can be better used. It is. In addition, the antenna 4 is coupled to the main body 2 in a screw structure and is configured to be separated from the main body is configured to be portable.

Next, a brief look at the process of using the conventional clamshell mobile phone (1) configured as described above. First, when a call is received from the other party, the information called from the other party is transmitted as an electric wave, and the electric wave is received by the antenna 4 to inform the user by causing the buzzer sound and the lamp on the top of the main body to blink. The user opens the cover 3 and presses the call button located on the upper left side of the function button 2a and makes a call while keeping the earpiece 3b close to the ear, and after all calls are made, the top of the function button 2a Press the end button on the right to end the call.

On the contrary, when the user makes a phone call, the cover 3 is opened to press the phone number of the other party using the number of the function button 2a and then press the call button on the upper left side to call the other party. The call signal of the other party is transmitted to the other party through the antenna 4, and after the call is made, press the end button located at the upper right of the function button 2a to end the call and close the cover 3 to carry.

The conventional foldable mobile phone as described above is a mobile phone that is much smaller than the conventional bar-shaped mobile phone because its size is smaller and lighter, but has the following problems.

This is very inconvenient because when the call is received from the other party or to check the message, it is impossible to cover the cover and must always open the cover. That is, since a display in which letters or numbers appear is located on the inner surface of the cover, a call reception or a message cannot be confirmed while the cover is covered, and there is a problem that can be confirmed only when the cover is always opened.

In addition, the cover has a structure that opens and closes the upper end of the main body as a rotating shaft, there is a problem that two hands must be used to open and close the cover when using the mobile phone. That is, while holding the main body of the mobile phone with one hand, the cover should be lifted upward with the other hand. In the above case, if the user is holding a heavy object in one hand, such an operation cannot be simply performed with one hand, and thus there is an inconvenience in that both hands must be used while the object is held down.

Accordingly, an object of the present invention is to provide a folding type mobile phone capable of receiving a call or checking a message even when the cover is closed by changing the structure of the folding type mobile phone.

In addition, the present invention is another object to provide a clamshell mobile phone to easily open or close the cover by simply pushing up and down the cover with a thumb while holding the mobile phone in one hand.

The present invention for achieving the above object is provided with a main body provided with a plurality of buttons on the lower portion of the front and the upper, and a display and a sign language for displaying letters and numbers on the outer surface connected to the main body and closed The cover is composed of a sliding opening and closing means for sliding the opening and closing of the cover with respect to the main body, the call / end button provided on one side on the cover and the main body and an antenna provided on one side of the upper surface of the main body, In the closed state, the call / end button is operated to receive a call and receive a message, and has a feature of providing a folding-type mobile phone which is opened and closed from the downward direction of the main body by sliding.

In addition, the sliding opening and closing means is formed by grooves formed from both sides of the front surface of the main body and the upper end portion of the front inclined upward, and formed at both ends of the inner surface of the cover to slide along the inside of the guide groove portion. It is composed of a sliding projection. The call / end button may be installed on the right side of the main body, the antenna may be installed on the right side of the main body, or the call / end button may be installed on the left side of the main body, and the antenna may be installed on the left side of the main body.

Therefore, by using the call / end button installed on the outside of the main body, the letters and numbers appearing on the display can be checked even when the cover is closed, so there is an advantage that it can be used conveniently.

Next, a preferred embodiment of the present invention having the configuration as described above will be described in more detail with reference to FIGS. 2 and 3.

As shown, the clamshell mobile phone 10 according to the present invention is largely composed of a main body 20, a cover 30, and an antenna 40.

First, the main body 20 will be described. The lower part of the upper surface of the main body 20 is located a talker 24 for recognizing the user's voice. On the upper side of the talker 24, a function button 22 indicating a number and a function is formed. The function button 22 is used when the user uses various functions given to the mobile phone such as dialing the other party's phone number or checking the transmitted message.

On the other hand, the call / end button 26 is located on the right side of the main body 20. The call / end button 26 is installed on the front surface of the main body in the conventional mobile phone, but is installed on the right side of the main body 20 in the present embodiment. This is to confirm the call reception and messages in a state in which the cover 30 to be described later is covered. That is, when a call is made to the other party or a message is received, the operation of the mobile phone is started only by pressing the call button 26. In this case, in the clamshell mobile phone 10, the call button is conventionally installed on the front of the main body so that only the cover can be opened. However, in the present embodiment, the cover 30 is installed on the right side of the main body 20. The call button 26 can be operated without opening. End button 26 can also be operated without opening the cover (30).

Next, the cover 30 will be described. The cover 30 has a structure that is opened and closed on the front of the main body 20, the receiving part 32 and the display 34 on the outer surface exposed to the outside while the cover 30 is covered on the front of the main body 20 Consists of a structure that is installed. The receiver 32 is located above the outer surface of the cover 30 to transmit a voice or a message of the counterpart transmitted to the user. In addition, the display 34 is a part where letters and numbers are displayed and is a part where calls and messages transmitted from the other party and various functions used by the user are displayed. Therefore, the display 34 is installed on the outer surface of the cover 30, so that the user can easily check the cover 30 without opening the cover 30 as well as the above-mentioned call / end button 26 installed on the outer surface of the main body 20. By operation, the message and the call transmitted from the other party can be confirmed without opening the cover 30. That is, according to the present invention, when the function button 22 should be used, for example, the cover 30 can be opened and used only when making a phone call, thereby making it more convenient to use.

In addition, since the display 34 is formed on the outer surface of the cover 30, the display 34 may have a larger size. Therefore, it is very advantageous to implement the display 34 as large as possible in the size of a given mobile phone. That is, in the related art, the display is installed on the inner surface of the cover, so that the screen size is limited to a certain size, but is configured to be as large as possible on the outer surface. Therefore, the display 34 can be made larger when video communication becomes common in the future, which is quite effective.

Next, in the present invention, the cover 30 is configured to be opened and closed by sliding in the main body. That is, in the prior art, a structure that opens and closes by rotating in an upward direction about a rotation shaft of the upper end of the main body 20 is constituted in a straight reciprocating motion in the front and rear directions in the present invention. Therefore, the cover 30 is slid forward so that the display on the outer surface of the cover 30 can be maintained as it is. Hereinafter, the sliding structure of the cover 30 will be described in more detail with reference to the drawings of FIGS. 4 to 7.

As shown, guide grooves 28 grooved inwardly are formed on both sides of the upper surface of the main body 20. The guide groove 28 is formed horizontally forward from the rear of the upper surface of the main body 20, and is formed to be inclined upward from the end side of the front of the main body 20. The guide groove 28 has a structure in which the locking projection 28a is formed on the upper side of the groove in which the sliding protrusion 36 is moved so that the sliding protrusion 36 to be described later is not separated.

When the cover 30 is completely covered, sliding protrusions 36 are formed at both sides of lower ends of the inner surface of the cover 30 at positions corresponding to the guide grooves 28 of the main body 20. The sliding protrusion 36 is installed inside the guide groove 28, and is movable in the front-rear direction along the guide groove 28.

That is, in the state in which the cover 30 is completely covered, the sliding protrusion 36 is caught by the lowermost end of the guide groove 28. In addition, when the cover 30 is completely open, the sliding protrusion 36 is positioned at the inclined guide groove 28 at the front end of the main body 20 so that the cover 30 and the main body surface are approximately separated. It is possible to achieve a constant inclination angle of about 150 °. Therefore, when the user needs to open the cover 30, the cover 30 is slid and opened as the user pushes the lower portion of the outer surface of the cover 30 with the thumb and pushes it forward.

Meanwhile, as shown in FIGS. 5 and 6, the cover 30 and the main body 20 are connected to each other by the flexible circuit a. That is, since an electrical signal for operating the display 34 and the receiver 32 of the cover 30 is transmitted from the main body 20, a circuit for transmitting a signal transmitted from the main body 20 to the cover 30. Is needed.

In the related art, the cover is opened around the rotation shaft of the upper end of the main body, and the center portion of the rotation shaft is fixed, so that a circuit is connected between the main body and the cover through the inside of the fixing part. However, in the present invention, since the cover 30 is made of a sliding structure, there is no portion fixed between the cover 30 and the main body 20, so that the flexible circuit (a) is used. That is, the flexible circuit (a) is installed through the upper end of the upper surface of the main body 20 and the lower surface of the cover 30 so that the main body 20 and the cover 30 are electrically connected to each other.

Meanwhile, as shown in FIG. 5, in the state in which the cover 30 is completely closed, the flexible circuit a is maintained in a fully expanded state. As the cover 30 is opened, as shown in FIG. 6, the flexible circuit a gradually contracts, and in the fully opened state, the flexible circuit a maintains the contracted state as much as possible. . Therefore, the flexible circuit (a) is installed between the cover 30 and the main body 20, and when the cover 30 is opened, the flexible circuit (a) is contracted according to the movement of the cover 30, so that the user is not exposed to the user at all. There will be no problem.

In addition, the structure in which the cover 30 slides in the main body is not limited to the method described above, and various modifications are possible. That is, the sliding structure may be achieved by using an elastic member such as a spring. In this case, when the cover 30 is closed, the spring is maintained in an elastically expanded state. When the cover 30 is opened, the cover 30 is slid by elastically recovering the spring by a simple push button or the like. The structure will be achieved.

Or if a micro motor is developed that is not possible with current technology but can be installed inside a mobile phone and a battery of sufficient capacity to drive the motor is developed, the lid can be opened by simply pressing a button with a back loading function. It could be sliding.

Next, an antenna 40 is installed on the upper right side of the main body 20 to hold radio waves transmitted and received. Since the antenna 40 has the same structure as in the related art, a detailed description thereof will be omitted below.

On the other hand, in the present embodiment described above, the call / end button 26 is installed on the right side of the main body 20, the antenna 40 has been described a structure that is installed on the upper right side of the main body 20, the call / end The button 26 and the antenna 40 are not limited to this structure. The above structure is mainly for the right handed using the right hand, for the left handed using the left hand the call / end button 226 is installed on the left side of the main body and the antenna 40 on the upper left side of the main body 20 It can also be achieved by installing on.

Next, the use process of the clamshell mobile phone 10 according to the present invention configured as described above will be described.

First, when a call is received from the other party, the user recognizes that the call is received from the other party by the buzzer sound and the blinking of the lamp. At this time, the user can simply make a call without opening the cover 30 as in the prior art. That is, since the display 34 is installed on the outer surface of the cover 30, the display shown on the display 34 can be recognized without the cover 30 being opened, and the display 34 is attached to the side of the main body 20. Press the call button 26 can be made to call immediately. When the call is over, simply press the end button 26 attached to the main body 20 side to end the call. In the above case, since all operations are made without opening the cover 30 at all, it is very convenient for the user to use the clamshell phone more simply.

On the other hand, if you need to call the other party should open the cover 30. In the related art, holding the folding mobile phone 10 itself with one hand and opening the cover 30 with the other hand was inconvenient. However, in the present invention, such a cover 30 can be easily opened with one hand. That is, when the mobile phone is held by the right hand, the force is applied upward while pressing the lower outer surface of the cover 30 with the thumb of the right hand. By the applied force, the cover 30 slides upward along the guide groove 28 to be easily opened.

Then, the sliding protrusion 36 formed on the inner surface of the cover 30 is slid until reaching the inclined guide groove 28 of the main body 20 so that the cover 30 is completely opened. In the above state, by pressing the number button 22 to make a call with the other party, after the call is over, the cover 30 is slid and closed by applying downward force using the thumb again. As described above, the opening and closing of the cover 30 is enough to use the thumb can be performed with one hand enough to be more convenient to use.

As described above, according to the present invention, in the clamshell mobile phone, a display is installed on the outer surface of the cover, and the call / end button is installed on the side of the main body, so that communication and messages of the other party can be checked without opening the cover, which is very convenient for use. There is an advantage to losing.

And, since the opening and closing of the cover is made by simply sliding with one hand, there is an advantage that the use of the mobile phone is very simple.

In addition, since the size of the display can be enlarged by installing the display on the outer surface of the cover, there is another effect of realizing a larger screen in a future video call.
