Description

Sub Body Angle Adjuster {DEVICE FOR ADJUSTING ANGLE IN SUB-BODY}

The present invention relates to a folding electronic device having a main body and a sub body installed to be able to flow at a predetermined angle on the main body. It relates to a sub-body angle adjusting device configured to enable the angle adjustment.

In recent years, due to the development of the electronics industry, various kinds of electronic devices have been released. In particular, while the electronic devices are becoming smaller and lighter in order to meet various needs of users, their functions are becoming more diversified.

As a way of miniaturization of the product as described above, the main body and the sub-body divided into a main body and the sub-body when the portable, do not use or in the standby state is used to fold the main body and the sub-body overlap each other.

The foldable electronic devices include a portable notebook PC, a portable terminal, an internet phone, and a phone (including a key phone) in which a main body composed of an LCD module flows at a predetermined angle on the base plate. The folding devices are configured to be adjustable at a desired angle for the user's convenience. Therefore, a predetermined hinge module is used to install the sub body to be opened and closed on the main body, and is designed in consideration of a predetermined opening and closing angle when opening and closing the sub body.

1a and 1b is a block diagram showing the opening and closing state of the LCD module according to an embodiment of the prior art, a predetermined hinge module on the body 110 and the LCD module 120 of the general telephone 100, respectively The brackets 111 and 121 are installed, and the bracket 121 of the LCD module is opened and closed in the direction of the arrow of FIG. 1B with respect to the main body bracket 111.

However, the sub-body opening and closing device having the above-described configuration with a predetermined hinge module has a disadvantage in that the rotation center point (pivot axis of the hinge module) can be adjusted only by using the hinge part because the center of rotation is on the phone. The problem arises that it is difficult to implement a product in this space.

In order to solve the above problems, the present invention is to provide a sub-body angle adjusting device configured to rotate while the angle is adjusted relative to the center of rotation in space.

Another object of the present invention is to provide a sub-body angle adjusting device is configured so that the angle is not adjusted arbitrarily when operating a component such as a key button of the sub body.

Still another object of the present invention is to provide a sub-body angle adjusting device configured to beautify the appearance of a product by not using a hinge module and preventing the angle adjusting device from being exposed to the outside of the device.

20: main body 30: base plate

33: rack gear 200: pinion gear

In a folding device having a main body and a sub body installed to be rotatable at a predetermined angle on the main body, the pinion gear having a predetermined anti-rotation means is provided on the contact surface of either the main body or the sub body. It is installed, the rack gear is meshed with the pinion gear is installed on the surface in contact with the other pinion gear of the main body or sub-body is characterized in that the guide.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the embodiment of the present invention, the telephone body including the LCD module as a sub-body, the base body supporting the telephone body as a main body and the base plate in which the main body is moved at an angle thereon, but other folding type It is apparent to those skilled in the art that the present invention can be applied to a folding device such as an LCD module which is opened at an angle on the main body.

2 is a perspective view of a telephone according to an embodiment of the present invention, the main body 20 is installed to be rotatable in the direction of the arrow on the base plate 30 including the handset mounting portion 31, the main body 20 It consists of a handset 60 is installed on one side. A plurality of key buttons 70 are installed on the main body 20, and in addition to the key buttons 70, a seesaw key assembly may be installed to perform a navigation function or another additional function. The LCD module 110 for displaying data is installed on the upper part of the key button 70. Preferably, the LCD module 110 may be a touch screen having a touch pad. In addition, an antenna device 50 may protrude from one side of the terminal 10.

3 is a partial perspective view showing an angle adjusting device of the phone according to an embodiment of the present invention, Figure 4 is a perspective view of the main portion of the angle adjusting device according to an embodiment of the present invention, the inner surface of the main body 20 On the pinion gear 200 is installed. The pinion gear 200 is installed so as to partially protrude from the upper surface of the base plate. More specifically, the pinion gear 200 is fixed to be rotatable by a predetermined bracket 80, the bracket 80 is installed on the inner surface 21 of the main body 20. In addition, one side of the pinion gear 200 may be provided with a rotation suppressing means, for example, may be at least one shaft 202 installed to have a predetermined frictional force in contact with the pinion gear 200, nuts Alternatively, it can be replaced with an E-ring. For example, the pinion gear 200 may be any known one installed so that the pinion gear 200 can rotate only when a certain rotation force is applied without idle rotation.
