Description

LOCKING DEVICE FOR PORTABLE TERMINAL}

The present invention relates to a portable terminal, and more particularly to a locking device for locking the housing to each other when the two housing is opened and closed by the hinge device.

A typical information terminal consists of two housings. Among these housings, one housing usually has an LCD for outputting information, and another housing is opened and closed by a hinge device in order to protect the LCD from an external environment.

As shown in Figures 1 and 2, the conventional portable terminal is composed of two housings, one of the two housings 300, 400, Fuku 310 is integrally formed, and the hook hole 410 that the hook 310 is caught Another housing 400 has a structure formed. Therefore, the hook 310 was inserted into the locking hole 410 and locked. The hook 310 is an injection molding, and thus, by retaining the tension force according to the characteristic of plastic, it is possible to lock or unlock the two housings 300 and 400 depending on whether the hook 310 is locked.

However, in the process of locking the two housings, fatigue phenomenon is repeatedly applied to the hook, and when such fatigue phenomenon is developed, a fatal problem occurs that the hook is broken. The fatigue phenomenon of the hook is caused by the forced coupling between the housings. As a result, there is a problem in the locking stability or reliability of the product.

The locking device made of the above-mentioned injection molding product is easy to be damaged in terms of forced coupling, and the reliability of the product is lowered. In view of such a problem, even if a separate spring is installed in the hole of the housing to reduce the load on the hook during locking, The fundamental solution was not made.

The present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to provide a housing with a fixed shaft, one housing in a terminal having a structure in which two housings are opened and closed around a hinge device as a center axis When defined as the rotation axis, the rocker and the spring is installed in one housing to provide a locking device of the portable terminal in pursuit of the operation stability and locking reliability of the rocker.

In order to achieve the above objects, the present invention is a locking device of a portable terminal,

The portable terminal includes an upper housing and a lower housing around a hinge axis, and a locking device installed on a plurality of ribs and bosses formed on the upper housing.

A rocker extending upwardly at an upper end thereof, a shaft formed at a lower end thereof to be rotatably placed on the rib, and having at least one support wall between the hook and the shaft; And

The locker has a pressing portion so that the rocker does not escape from the rib, and on one side there is a tension portion configured to contact the support wall to provide a force to return the rocker rotating about the shaft to its original position, and on the other end is perpendicular to the boss It consists of a leaf spring having a fastening portion having a fastening hole fastened in the direction.

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.

3 is a perspective view showing a portable terminal according to an embodiment of the present invention. Figure 4 is a side view showing a portable terminal according to an embodiment of the present invention. Referring to the drawings,

The portable terminal of the present invention shown in the drawing means a portable composite information terminal, and is composed of an upper housing 100, a lower housing 200, and a hinge device 300. At this time, the upper housing 100 is a mobile phone, the lower housing 200 is a computer. The upper housing 100 and the lower housing 200 are connected by the hinge device 300 and electrically connected from the lower housing 200 to the upper housing 100 by a flexible printed circuit (not shown). Accordingly, the upper housing 100 has a piece 110 disposed at an upper end thereof, an LCD 120 is mounted below the ear piece 110, a keypad 130 is disposed below the LCD 120, and a microphone device 140 is installed at the bottom of the upper housing 100. In addition, although not shown in the drawing, the lower housing 200 exposes the LCD and several switches.

4 and 5, the locking device according to an embodiment of the present invention is installed in the upper housing 100, the locking hole 210 corresponding to the locking device is formed in the lower housing 200.

The locking device is composed of a rocker 1 and a leaf spring 2. The locking device performs a locking operation by interlocking with the rocker 1 and the leaf spring 2.

As shown in FIG. 6, a plurality of seating ribs 170 and a fastening boss 180 are formed in the upper housing 100 so that the locking device is installed.

The configuration of such a locking device will be described in detail with reference to FIG. 7 as follows. The locking device of the present invention comprises a rocker 1, a leaf spring 2 supporting the rocker 1, a rib 170 on which the rocker 1 is seated, a screw 180 for fastening the boss 180 and a leaf spring 2 to the boss 180. . Such a locking device is disposed in the vertical direction, is installed in the upper housing 100.

At this time, the rocker 1 has a hook 11 protruded upwards at the top, a shaft 12 is formed so as to reliably lie in the slot 171 formed in the rib 170 at the bottom, three support walls 13 are formed in the middle. At least one support wall 13 is formed between the hook 11 and the shaft 12.

In addition, the leaf spring 2 is provided with a fastening portion 23 having a fastening hole 23a at one end thereof, and a tension portion 22 elastically supporting the support wall at the other end thereof. At this time, the tension unit 22 is assembled with the rocker 1 to provide a force to return to the original position. Further, the rib 170 formed on the upper housing 100 is formed to face each other, the fastening boss 180 is formed in a close position. Operation of the locking device having the above configuration will be described with reference to FIGS. 8 and 9 as follows. .

FIG. 8 is a view illustrating a locking device in which a terminal is closed, and FIG. 9 is a cross-sectional view illustrating a state in which a locker is pressed to open a terminal. Referring to the drawings,

When the shaft 12 of the rocker is placed on the seating rib 170, and the leaf spring 1 is fastened to the boss 180 by the screw S, the shaft 12 is pressed by the pressing portion 21 of the leaf spring and moved in the direction of the arrow by the tension portion 22. Get the power to do it. The release of the rocker 1 is prevented by the pressing part 21 of the leaf spring. The locking state is maintained by this tension unit 22. In the locking device of the present invention, the screw S, the leaf spring 2, the rocker 1 and the rib 170 and the boss 180 are sequentially placed in the vertical direction.

On the other hand, as shown in Figure 9, the user presses one side of the rocker 1 in the direction of the arrow to release the locking state of the terminal, the rocker rotates counterclockwise around the shaft 12. The tension portion 22 supporting the rocker then retracts slightly, and the hook 11 of the rocker retreats slightly from the hole. Next, the user rotates the upper housing 100 about the hinge axis in the direction of the arrow to release the locked state of the terminal. At this time, when the user removes the force applied to the rocker, the rocker returns to its original position. This return force is provided by the tension section 22.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but 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 can stably maintain locking in a portable terminal, is convenient for use, and provides high reliability to a product.
