Description

Two-sided flip phone

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flip type mobile phone, and more particularly, to a flip up down type mobile phone having a flip cover installed above and below the main body.

In general, a portable device such as a car phone, a PCS, and a CT-2 is widely used as a portable terminal, and the portable terminal includes a bar type and a flip type. Currently, the bar type and the flip type coexist, and the flip type mobile phone is becoming more and more common. The reason why such a flip type mobile phone is widely used is that the flip cover installed in the main body protects a plurality of keys and performs a role of a negative reflector so that the sound sensitivity is excellent. In addition, flip-type mobile phones are advantageous for miniaturization and design of device sets.

Furthermore, in the current trend, such portable devices are pursuing further miniaturization of design and weight reduction of products. Accordingly, in the flip type portable devices, miniaturization is being pursued by installing a microphone or a sputter on a flip cover. Miniaturization is accelerated by connecting a microphone or a speaker to the main body using a separate connection means.

Such flip type mobile phones have a flip up type and a flip town type. The flip up type is a type in which a flip cover is installed and opened at an upper side of the device body, and the flip down type means a flip cover is installed in a lower side of the device body and opened and closed. In addition, a flip up down type mobile phone means installing flip covers on both sides of the main body. This is a double flip phone.

In addition, the flip-type mobile phone is essentially installed the flip cover opening and closing device to implement the call angle. Therefore, the mobile phone is largely composed of a main body, a flip cover and a flip cover opening and closing device.

This conventional two-stage flip type mobile phone is shown in FIG. As shown in FIG. 1, the upper flip cover 10 of a conventional mobile phone protects a speaker, an LCD, and the like, and the lower flip cover 20 protects a plurality of keys. The speaker is installed above the main body 100, and the microphone is installed below the main body 100. In the figure, the speaker is obscured in the figure by the upper cover 10. In addition, flip cover opening and closing devices are respectively built in the accommodating parts 110 and 120 of the main body.

In such a conventional flip type mobile phone, in particular, when the user opens and closes the flip cover to make a call, the inconvenience of having to open one flip cover and then open the other flip cover occurs. Originally, the flip-type cell phone has been generalized because of the advantages already described, but there is an inconvenience to open the flip cover, and in both flip-type cell phones, inconvenience has to be opened once more. In particular, since the mobile phone is frequently held by the main body with one hand and the flip cover is opened frequently, the mobile phone is a cause of great inconvenience in a mobile phone having two flip covers installed.

The present invention has been made to solve the above-mentioned conventional problems, the object of the present invention is to provide a flip-flop mobile phone that can be opened and closed at the same time in the flip-flop mobile phone at both ends.

In order to achieve the above objects, the present invention forms gear teeth on the surface of both coupling portions of the upper and lower flip cover, having gear teeth engaged with the gear teeth, and according to the opening and closing of the upper and lower flip cover Each of the first and second racks facing each other is installed on the main body, and the pinion gear rotating about the hinge axis between the racks is interposed to engage the gear teeth, so that one flip cover is automatically opened according to opening and closing of one flip cover. Open and close simultaneously.

Hereinafter, with reference to the accompanying drawings will be described in detail the most preferred embodiment of the present invention. First, in describing each of the drawings, only the same components have the same reference numerals as much as possible even if shown on different drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

2 is a perspective view showing a two-stage flip-type mobile phone according to an embodiment of the present invention. In the drawing, both flip covers 10 and 20 are closed. Among the flip covers, the upper flip cover 10 is provided with a speaker, and the lower flip 20 cover is provided with a microphone. The flip cover opening and closing device, not shown in the drawing, is built in the accommodating parts 110 and 120 for the call angle of each flip cover.

At this time, the lower flip cover 20 is automatically opened and closed simultaneously with the opening and closing of the upper flip cover 10, or the upper flip cover 10 is automatically opened and closed simultaneously as the lower flip cover 20 is opened and closed. The transfer device is installed over both sides of the main body which is interlocked with the flip cover. On the other hand, such a moving device is also preferably installed on only one side of the main body. The mobile device is not shown in the figure.

3 is a perspective view showing a flip cover according to an embodiment of the present invention. In this figure, since the gear teeth are formed only at one side of the flip cover, the moving device interworking with the gear teeth is installed only at one side of the main body, but as described above, the gear teeth are coupled to both sides of the flip cover. When formed in, it means that the moving device is interlocked with each other installed on both sides of the body. Referring to the drawings,

In this drawing, only the upper flip cover 10 is illustrated, but the lower flip cover has the same shape. However, the upper flip cover includes a speaker 11 and the lower flip cover includes a microphone. The upper flip cover 10 of the present invention, the speaker 11 is installed in the center, the neck 101 is formed at both ends, the coupling portion 102 is formed to be coupled to the main body. Gear teeth 1031 are formed at predetermined intervals of the surface 103 of the coupling portion 102. The gear teeth 1031 extend along the engagement surface 103. Accordingly, the gear teeth 1031 may be interlocked with a moving device, not shown, according to opening and closing of the flip cover.

Referring to the drawings, as described above, the mobile device of the present invention is preferably installed over one side or both sides of the main body. This shifting device consists of two first and second racks 30 and 40 and a pinion gear 50 engaged therebetween. Among the racks, the first rack 30 has gear teeth 311 engaged with the gear teeth of the lower flip cover at regular intervals on one side thereof, and gear teeth 312 are formed on the other side thereof so as to engage with the pinion gear 50. Another second rack 40 has gear teeth 412 meshing with the pinion gear on one side of the upper surface, and gear teeth 411 meshing with gear teeth of the upper flip cover on the other side.

Accordingly, the pinion gear 50 engaged between the racks 30 and 40 rotates about the hinge shaft 501. In addition, the two racks 30 and 40 perform a linear reciprocating movement (arrow direction) about the pinion gear 50 as the flip cover is opened and closed.

FIG. 5 is a side view illustrating a state in which both ends of the flip cover are closed according to an exemplary embodiment of the present invention, and FIG. 6 is a side view illustrating an open state of both flip covers according to the preferred embodiment of the present invention. Referring to the drawings,

Opening the flip cover of either the upper flip cover 10 or the lower flip cover 20 in the A direction to make a call, the first and second racks 30 and 40 engaged with the gear teeth 1031 and 2031 of the flip cover simultaneously move in the B direction. At the same time, the pinion gear 50 rotates clockwise. All movement in the direction of the arrow in this figure takes place simultaneously. Gear teeth 1031 and 2031 are formed at the engaging portions of the upper and lower flip covers 10 and 20, gear teeth 311 and 411 engaging with the gear teeth are formed in the first and second racks, and pinion gear 50 is formed on the gear teeth 312 and 412 of the rack. As an engagement, the limited rotation of the flip cover results in a limited linear reciprocating movement of the rack, and the pinion gears have a rotational movement about the hinge axis.

To close the flip cover by ending the call, first, one of the two flip covers 10 and 20 is closed, and the other flip cover is automatically closed at the same time. That is, when the upper flip cover 10 is closed in the C direction, the second rack 40 simultaneously moves linearly around the pinion gear 50 (D direction), and the first rack differs by the pinion gear 50 (counterclockwise). 30 degrees linear movement, the lower flip cover 20 is also closed according to the linear movement of the rack 30. All movements take place simultaneously by interlocking the flip cover with the rack and pinion gear.

As a result, when one flip cover is opened in both flip-type mobile phones, the other flip cover is automatically opened simultaneously and the user is convenient.

On the other hand, in the detailed description of the present invention has been described with respect to specific embodiments, it will be apparent to those skilled in the art that various modifications are possible without departing from the scope of the present invention.

As described above, the present invention is convenient in the user's position by automatically opening and closing the other flip cover according to one flip cover opening and closing operation in the two-stage flip-type mobile phone, which is advantageous for miniaturization.
