BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding type opening and closing device of a portable terminal, and more particularly, when a force is applied to a slide body of a portable terminal only at an initial stage, the opening and closing of the portable terminal is performed automatically and in a sliding manner. It relates to a sliding type opening and closing device of a portable terminal to maintain a stopped state by the switchgear.

In recent years, as the penetration rate of portable terminals increases, additional functions that are suitable for the user's taste are required not only for their own functions but also for opening and closing operations.

In response to these demands, portable terminals have evolved from general bar types to flip types, flip up types, folder types, and the like. To achieve. This is because the folder type terminal has enough space to adopt the wide LCD module as a display device, and because it is folded in half and portable, the portability is superior to other terminals.

More recently, portable terminals having a slide device having a wide LCD module having a size similar to that of a folder type terminal and having a slide type opening and closing device that can contribute to miniaturization of the terminal have been developed.

The sliding terminal has an additional advantage that the sub body corresponding to the cover is opened and closed by the sliding operation on the main body, and is opened and closed by the new operation while maintaining the advantages of the existing folder type terminal.

An example of such a sliding type portable terminal may be the sliding type portable wireless terminal disclosed in Utility Model Registration No. 0308165. According to this utility model registration, the portable terminal is a guide means for guiding the slide body on the main body and the direction of the pressing force in the opening or closing direction based on a certain sliding position of the slide body between the slide body and the main body. At least one elastic means is installed to change. By means of elastic means the slide body can maintain the maximum open position or the maximum closed position without a separate stopper in the fully open or closed operation. As such elastic means, a torsion spring is adopted in which one end is fixed to the main body and the other end is fixed to the slide body.

In such a terminal, one end of the torsion spring is fixed to the main body and the other end is fixed to the slide body, so that the torsion spring is elastically applied over the entire moving distance of the slide body, so that the torsion spring is greatly tensioned and unfolded. For this reason, the torsion spring has a large motion while using less elastic force, and two torsion springs are disposed to compensate for the insufficient elastic force.

However, in the sliding type opening and closing device according to the utility model registration, the torsion spring is greatly deformed, so there is a fear that the torsion spring is easily aging due to fatigue due to repetitive operation and loses its normal function early.

Furthermore, in such opening and closing devices, not only should at least two torsion springs be used for the desired opening and closing operation, but also the number of turns of each torsion spring must be at least two times. Note that the spacing between the main body and the slide body depends on the wire diameter of the torsion spring itself (meaning the diameter of the spring cross section) and the number of turns of the torsion spring. That is, as the wire diameter of the torsion spring itself increases and / or the number of turns of the torsion spring increases, the space between the main body and the slide body inevitably increases. For example, assuming that the diameter of the torsion spring is 0.5 mm and this torsion spring is wound twice, the separation distance between the main body and the slide body should be at least 1.0 mm. This increases the volume of the portable terminal, which in turn reduces the portability of the portable terminal.

Moreover, in the opening and closing apparatus described above, the variation in force depends on the adjustment of the angle of the torsion spring. Thus, it becomes difficult to adjust (or control) the force in sliding between the main body and the slide body of the portable terminal. This may shock the portable terminal itself, and will eventually shorten the life of the portable terminal itself unless a separate shock absorbing or shock mitigating means is provided.

The present invention has been made in order to supplement and / or solve the problems of the prior art as described above, an object of the present invention is to smoothly maintain the sliding of the slide body with respect to the main body of the portable terminal that is opened and closed in a slide manner It is to increase the portability by reducing the volume of the portable terminal itself by minimizing (slimming) the distance (D of FIG. 1).

Still another object of the present invention is to reduce the force variation applied between the main body and the slide body of the portable terminal by itself, as well as to extend the life of the portable terminal, as well as the sliding method of the portable terminal that enables fine adjustment of the force It is to provide a switchgear.

In order to achieve these and other objects, the present invention,

In the sliding type opening and closing device of a portable terminal having a main body and a slide body that can operate in a sliding manner with respect to the main body,

In addition, in the sliding type opening and closing device of the portable terminal according to the present invention, the distance between one end of the first elastic member and one end of the second elastic member is between the other end of the first elastic member and the other end of the second elastic member. Is greater than the distance. This leads to the concentration of force and consequently enables sliding of the slide plate relative to the stationary plate with less force.

In addition, in the sliding type opening and closing device of the portable terminal according to the present invention, the fixing plate and the slide plate are preferably made of plastic. The choice of plastic material to these plates makes it easier to provide the fixed plate side guide rod through hole and the slide plate side guide rod through hole. In addition, the manufacturing process of all these plates can be simplified.

As mentioned above, in the sliding type opening and closing device of the portable terminal according to the present invention, since the sliding operation of the slide plate (or the slide body) with respect to the fixed plate (or the main body) is made by a zigzag spring, the portable terminal Its thickness can be made smaller (slimming effect) , and at the same time, the deviation of sliding-generating force is small, so that the sliding deviation of the portable terminal can be reduced, so that the sliding of the portable terminal can be performed more smoothly (smooth sliding operation).

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, referring to FIG. 1, a sliding type opening and closing device (hereinafter, referred to as a 'slide opening and closing device') of a portable terminal according to a preferred embodiment of the present invention is a fixing plate 120, preferably a fixing plate 120 of plastic material. , A slide plate 110, preferably a slide plate 110 made of plastic, and a zigzag spring 134A and 134B disposed in a space between the fixing plate 120 and the slide plate 110, and the fixing plate 110. Sliding guide means 114A, 114B, 124A, 124B, 124A ', 124B', 134A and 134B for guiding the sliding motion of the slide plate 110 with respect to the plate 120.

The fixing plate 120 is coupled to various ways known to the main body (not shown) (eg, screwing, welding). The slide plate 110 is coupled to the slide body (not shown) in a variety of ways (eg, screwing, welding). The fixed plate 120 and the slide plate 110 are slidable with the aid of sliding guide means 114A, 114B, 124A, 124B, 124A ', 124B', 134A, 134B as shown. To be combined. The coupling method thereof is illustrated as a dotted line in FIG. 1, and a person skilled in the art may easily combine the fixing plate 120 and the slide plate 110 with reference to the perspective view of FIG. 2. The sliding guide means includes a fixed plate side guide rod through hole indicated by reference numerals 124A, 124B, 124A ', and 124B', a slide plate side guide rod through hole indicated by reference numerals 114A and 114B, and a slide therethrough. Sliding guide rods 134A and 134B to be fitted are included. 1 and other figures, although the fixing plate side guide rod through holes 124A, 124B, 124A 'and 124B', the slide plate side guide rod through holes 114A and 114B, and the sliding guide rod ( Although the cross sections of 134A and 134B are shown in a circular shape, they may have other types of cross sections that are slidable (eg, triangular cross sections, square cross sections, etc.). Although not shown in FIG. 1 and other figures, it should be understood that the ends of the fixing plate side guide rod through holes 124A and 124B are closed for securing the guide rods 134A and 134B.

The slide opening and closing device 100 includes at least one elastic member (eg, a first elastic member (shown on the left side in the drawing) and a second elastic member) to adjust the sliding of the slide plate 110 with respect to the fixing plate 120. Is shown on the right side of the drawing). One end of the first elastic member 142A is supported by the fixing plate 120, and the other end thereof is supported by the slide plate 110. Similarly, one end of the second elastic member 142B is supported by the fixing plate 120, and the other end thereof is supported by the slide plate 110. However, one end of the first elastic member 142A, one end of the second elastic member 142B, the other end of the first elastic member 142A and the other end of the second elastic member 142B should be located at different levels. They must be arranged so that they do not overlap each other. In addition, one end and the other end of the first elastic member 142A and one end and the other end of the second elastic member 142B are rotatably coupled to the fixing plate 120 and the slide plate 110 (122A, 122B) ( 112A) 112B. The expression "level" used in this paragraph should be interpreted as defined above. In a preferred embodiment of the present invention, the first elastic member 142A and the second elastic member 142B are zigzag springs. If the distance between one end of the first elastic member 142A and one end of the second elastic member 142B is greater than the distance between the other end of the first elastic member 142A and the other end of the second elastic member 142B, It is advantageous to concentrate.

2A to 2C show the state of the sliding switch when the portable terminal is completely closed (perspective view, front view and side view in sequence). Referring to these figures, one end of the first elastic member 142A is supported by the fixing plate 120 and the other end is supported by the slide plate 110. The first elastic member 142A has a lateral direction (first side) perpendicular to the direction in which the slide plate 110 is closed and the moving direction of the slide plate 110 based on the inflection point S (1/2 points of d). Direction), and when the slide plate 110 is close to the open position based on the inflection point S, the elastic force is applied in the direction in which the slide plate 110 is opened and in the first lateral direction. As described above, one end of the second elastic member 142B is supported by the fixing plate 120, and the other end thereof is supported by the slide plate 110. When the second elastic member 142B is close to the position where the slide plate 110 is closed based on the inflection point S, the second elastic member 142B is closed in the slide plate 110 and in a direction opposite to the first side direction (second side direction). When the elastic force is applied to the position where the slide plate 110 is opened based on the inflection point S, the elastic force is applied in the direction in which the slide plate 110 is opened and in the second lateral direction. The first elastic member 142A and the second elastic member 142B are used to generate elastic force in different lateral directions based on the direction in which the slide plate 110 moves, using only one elastic member or two When the elastic member causes the force to be generated in the same lateral direction, the slide plate 110 exerts a biased force against the fixed plate 120, so that the sliding guide rods 134A and 134B and the slide plate side guide rod through-holes. This is because the 114A, 114B and the fixing plate side guide rod through holes 124A, 124B, 124A 'and 124B' may be damaged or short-term wear. The inflection points S of the first elastic member 142A and the second elastic member 142B coincide with each other to smoothly operate the slide plate 110.

3A to 3C show the state of the sliding opening and closing device when the portable terminal is fully opened (perspective view, front view and side view in sequence). Since the operation of the sliding opening and closing device shown in these figures is opposite to the closing operation as described above, a description thereof will be omitted.

In a preferred embodiment of the present invention, a zigzag spring as described above is used as the first elastic member 142A and the second elastic member 142B. The use of such springs makes it possible to slim down portable terminals. More specifically, the space between the fixing plate 120 and the slide plate 110 (FIGS. 1, D) depends on the space occupied by the spring, and in a preferred embodiment of the present invention only depends on the wire diameter of the spring. If torsion springs are used instead of zigzag springs, you will need twice as much space as the diameter. In addition, in this case, since the variation of the force in the sliding switchgear depends on the adjustment of the angle of the torsion spring, it is difficult to adjust (or control) the force in the sliding between the main body and the slide body of the portable terminal. Lose. That is, the portable terminal itself may be shocked, and if no separate shock absorbing means or shock mitigating means is provided, it will eventually shorten the life of the portable terminal itself. Alternatively, if a compression spring is used instead of a zig-zag spring, it will require twice as much space as the spring diameter, as well as the diameter of the space occupied by the wound inside of the compression spring. However, the elastic member used in the preferred embodiment of the present invention, i.e. the zigzag spring, makes it possible to supplement and solve the problem of the compression spring as well as the problem of the torsion spring as described above. In another aspect, enabling the use of such a zigzag spring is that one end and the other end of the first elastic member 142A and one end and the other end of the second elastic member 142B are located at different levels as described above. This is because the first elastic member 142A and the second elastic member 142B are arranged so as not to overlap each other.

As described above, in the sliding type opening and closing device of the portable terminal according to the present invention, since the sliding operation of the slide plate (or the slide body) with respect to the fixed plate (or the main body) is made by a zigzag spring, Since the thickness can be made smaller (slimming effect) and the sliding-generating force variation is small, the sliding variation of the portable terminal can be reduced, so that the sliding of the portable terminal can be smoothly performed (smooth sliding operation effect). In addition, the effect of extending the life of the portable terminal itself (life extension effect due to impact reduction) is achieved.

Although the above has been described with reference to the preferred embodiments of the present invention, those skilled in the art have various modifications of the present invention without departing from the spirit and scope of the present invention described in the claims below. And can be changed.
