Description

Operating system of cellular phone's folder

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a clamshell mobile phone capable of automatically opening and closing a folder. More particularly, the present invention relates to a folder opening and closing apparatus of a mobile phone capable of miniaturizing a device by improving a structure of opening and closing a folder.

In general, a cellular phone (Cellular Phone / Personal Communication Services) is a terminal that receives a mobile communication service to enable the use within a certain radius within the service area by radioizing a part of the locally fixed subscriber line. Whereas the communication is used in a fixed place by line number, the mobile phone can make a call without restriction in place by a logical personal number regardless of line.

Such a mobile phone is explosive in demand due to its ease of portability and convenience in use, and is becoming a miniaturized and multifunctional device in order to meet various needs of consumers.

In general, a mobile phone has a bar type in which the number (function) button is exposed to the outside according to its shape, a flip type having a cover shielding the number (function) button with a cover, and a main body. It is classified into a folder type that is folded in half, and according to the trend of miniaturization, the spread of folder type mobile phones is increasing.

1 is a perspective view showing a general folding type cellular phone according to the prior art.

The conventional mobile phone 100 is composed of a main body 110 and a folder 120, the main body 110 is usually provided with a number (function) button and a microphone, there are various components for handset inside Built-in, the battery pack (B) for supplying power to one side is made.

The folder 120 includes a display window for displaying various call information and function information, a speaker, and the like, as well as various components.

In this folding type mobile phone, one end of the folder 120 is supported by the hinge means with respect to the main body 110. The folder 120 is opened and closed by rotating in the forward or reverse direction about the hinge means.

However, in the conventional mobile phone 100 as described above, since the weight of the folder 120 is relatively heavy, in order to open and close the folder 120, the folder 120 must be opened with the other hand while holding the main body 110 with one hand. There was an inconvenience.

In order to improve such a problem, a mobile phone 100 has been recently proposed to open and close the folder 120 more easily. The representative method is to use a driving means.

That is, the folder 120 is automatically opened and closed by operating the driving means by operating the switch with one hand, and the most important consideration here is that it must be used by using both automatic and manual.

2 is a cross-sectional view showing the configuration of the driving means in the auto clamshell cellular phone according to the prior art.

As shown, the main body 110 of the mobile phone 100 is provided with a pair of fixing portions 111, the fixing grooves formed in a direction facing each other on one side, the folder 120 is the pair of fixing portions 111 Rotating portion 121 is positioned between the, and the rotating portion 121 is cylindrical, one side is rotatably connected to the fixing portion 111 and the other side has an open shape.

The mobile phone 100 is provided with a driving means in the rotating unit 121, the driving means is a motor 116 receiving the elastic support force of the elastic means 112 on one side and the output end of the motor 116 It consists of a gearbox 117 configured to.

And, at the output end of the drive means is configured a power transmission means that is selectively restrained and released.

The motor 116 is operated in conjunction with a switch receiving a user's operation force, and generates a predetermined driving force only for a time set by a timer built in the mobile phone 100.

The gear box 117 is connected to the output end of the motor 116 to reduce the rotation ratio and at the same time prevent the reversal, the power transmission means is configured on the output end side.

The power transmission means is formed in the male coupler 113 connected to the drive means and the shaft, and the fixing portion 111 of the main body 110, which is a position opposite to the male coupler 113, and selectively with the male coupler 113. Constrained and unconstrained female coupler (114).

The power transmission means is subjected to the support force of the elastic means 112 installed on one side of the motor 116, the motor 116 by the elastic means 112 having a greater elastic support force than the drive torque of the motor 116. When the drive of the will remain bound to each other.

When the mobile phone 100 operates the switch to automatically open the folder 120, the male coupler 113 and the female coupler 114 are in engagement with each other. The sieve will rotate.

Therefore, the folder 120 having a cylindrical housing in which the motor 116 is installed is also rotated for a predetermined time to achieve an open state from the main body 110.

On the contrary, when the switch is re-operated to close the folder 120, the outer body of the motor 116 is rotated in the reverse direction using the male coupler 113 as a fixed point, so that the folder 120 is also rotated in the reverse direction and closed.

On the other hand, when the folder 120 is rotated in one direction or the reverse direction from the main body 110 in order to manually open or close the folder 120, since the action force applied to the folder 120 is greater than the bearing force of the elastic means 112, Slip is generated between the coupler 113 and the female coupler 114, and the male coupler 113 and the motor 116 integrally compress the elastic means 112 to cause position displacement, so that the folder 120 rotates. Will be achieved.

When the folder 120 reaches a predetermined position, the male coupler 113 is returned to its original position by the elastic support force of the elastic means 112, and the folder 120 rapidly opens by being recombined with the female coupler 114. It is closed.

However, the folder opening and closing device of the conventional mobile phone 100 is the male coupler 113 and the motor 116 integrally compress the elastic means to cause a change in position, the folder 120 is rotated and the elastic Since the means 112 are mounted in the pivoting part 121, a minimum clearance for rotation is required between the inner diameter of the pivoting part 121 and the outer diameter of the elastic means 112 and the elastic means 112 is also provided. The length of the rotating part should be increased by the length of). Therefore, the increase in the diameter and the length of the rotating part is directly connected to the design (design) constraints, and in this case, it is pointed out as a big problem in view of the recent trend of device miniaturization. This is sometimes referred to as a decrease in design freedom.

On the other hand, due to the structural feature of mounting the elastic means 112 in the rotating part 121 there is a problem that the workability is poor.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to carry a portable device which can simplify the structure and reduce the size of the device by mounting an elastic means that acts on the power transmission means in the fixing portion. The purpose is to provide a folder opener of a telephone.
