Description

Sliding apparatus for sliding type mobile communication terminal

The present invention relates to a sliding device provided in a sliding type mobile communication terminal, and the like, comprising: an elastic piece providing an elastic pressure-tightening force to the housing itself constituting the sliding device in the closed and open positions of the two main bodies constituting the sliding type mobile communication terminal; The present invention relates to a sliding device of a sliding type mobile communication terminal having a simplified structure, reduced parts, and easy assembly to improve mass productivity.

Recently, a bar type mobile communication terminal has been released as a form of a general mobile communication terminal. The bar-type mobile communication terminal as described above is manufactured similar to the form of the previous wireless telephone, and has been improved to a compact size so as to be easily carried according to battery capacity. However, in the case of a bar-type mobile communication terminal, the keypad is exposed to the outside, so that the keypad is easily damaged. To solve this problem, a folder type mobile communication terminal has been disclosed.

The foldable mobile terminal has a variety of designs that reduce its length and suit the user's taste. However, the clamshell mobile communication terminal also has a structure that can open and close the folder when making a call or carrying, so that the hinge portion connecting the upper folder and the lower folder is easily damaged or the external shock caused by the sliding impact between the upper and lower folders. There is a problem that causes damage to the case and the internal circuit board.

Therefore, recently, sliding type mobile communication terminals have been proposed to solve the above-mentioned general problems.

The sliding type mobile communication terminal is largely divided into a main body part and a sliding part, and has a structure in which the sliding part can slide on the main body part, and connects the main printed circuit board (main PCB) and the keypad printed circuit board (keypad PCB). Electrical and circuit connections were made using flexible printed circuit boards.

The body part and the sliding part of the sliding type mobile communication terminal are stacked in parallel to each other in a closed state. One side of the main body or the sliding portion is provided with a guide member for guiding sliding, and a slider for reciprocating sliding movement along the inside of the guide member is provided. The main body portion or the sliding portion, which is not provided with the guide member, is coupled to the slider so that the main body portion and the sliding portion slide relative to each other. For example, when the guide member is provided in the main body portion, the sliding portion is coupled to the slider of the guide member and reciprocally slides together.

1 is a plan view showing a rear surface of a conventional slide type mobile communication terminal.

The sliding part 10 having a display screen (not shown) on the front side and the main body part 20 having the battery 22 coupled to the rear side are stacked in parallel with each other to open or close by a reciprocating sliding motion in a horizontal direction.

The opening and closing position locking device for locking the opening and closing position between the main body portion and the sliding portion is provided, the guide groove 11 is formed on the back of the sliding portion 10 and a guide member (not shown) for guiding sliding therein It is provided, the guide member is provided with a slider for reciprocating sliding movement along the inner side, one side of the main body portion 20 is coupled to the slider sliding portion 10 and the main body portion 20 is relatively sliding. .

Here, an elastic member such as a coil spring or a spring is provided between the guide member and the slider to provide a restoring force in an open direction when the terminal is closed so that the terminal can be opened automatically when the terminal is opened. In spite of the restoring force of the elastic member, the elastic fixing means is provided to temporarily fix the sliding part and the main body part in the closed state and the open state. When a force is applied, the fixing is released to allow movement by the restoring force of the elastic member.

Such a guide member, slider, elastic member and elastic fixing means are usually provided as one module. Hereinafter, an example of a conventional semi-automatic slide module will be described. 2A to 2C are detailed views of a slide module of a conventional slide type mobile communication terminal, 2a is a plan view of the slide module 50, 2b is a rear view, and 2c is an elastic fixing of the slider 60. The means 70 and the elastic member are detailed cross-sectional views.

The slide module 50 is connected to a guide rail 51 for guiding sliding, a slider 60 reciprocating along the guide rail 51, and one end of the guide rail 51 from the slider 60. It is made of a coil spring 52 to provide a restoring force.

Fixing grooves 71 and 72 for temporarily fixing the slider 60 are formed at both ends of the bottom surface of the guide rail 51, and the slider 60 includes a pressing spring 73 and the pressing spring ( 73 is provided with an elastic fixing means 70 including a fixing ball 74, a portion of which is pushed out of the housing.

The slider 60 may be temporarily fixed by the fixing ball 74 caught in the fixing groove 71 on one side in a state of receiving a restoring force by the tensioned coil spring 52, and a force of a predetermined size or more in the sliding direction. When receiving, the compression spring (73) for pressing the fixing ball 74 is compressed while sliding is released until it is fixed to the opposite side fixing groove (72).

However, when the pressing force of the pressure spring 73 in the elastic fixing means 70 is increased, the magnitude of the force required when the user opens or closes the terminal becomes too large, causing inconvenience to the user, and causing the elasticity. Fixing means have a problem that is easy to break. On the other hand, if the pressing force of the pressing spring 73 is reduced, there is a problem that the terminal opens even with a slight shock generated when the terminal is carried. In particular, when the terminal opens by itself due to a vibration reception signal or the like when the mobile communication terminal is incoming, various problems may occur because the user is connected to the other party without knowing.

This problem is not limited to a mobile communication terminal having a slide module having the structure shown in FIG. 2, but is a conventional slide type mobile communication having various types of slide modules, including a spring-shaped elastic member and an elastic fixing means. Common to terminal.

In addition, such a conventional slide-type slide module has a complicated configuration, there is a problem that the number of manufacturing process is increased, the productivity is inferior.

Therefore, in order to solve the problems described above in the present invention, in the sliding device for slidingly moving the two main body constituting the sliding terminal, the component itself constituting the sliding device in the closed and open position of the two main body It is an object of the present invention to provide a sliding device of a sliding type mobile communication terminal by simplifying its configuration, reducing components, and improving mass productivity by forming an elastic piece that provides a fastening force by elastic pressure.
