The present invention relates to a semi-automatic slide type mobile communication terminal, and more particularly, to a slide type mobile communication terminal which is opened and closed automatically using a predetermined link and a cross-sectional cam.

In general, the slide-type mobile communication terminal has a slide structure that is provided on the upper body, the lower body and the contact surface of the upper body and the lower body that are superimposed on each other so that the two parts are relatively sliding to open or close.

A conventional mobile communication terminal having a slide module includes a slide module which is fixed to one side and includes a guide for guiding sliding and a slider for reciprocating sliding movement along the guide, wherein the slider is opposite to the side on which the guide is fixed. Is fastened to the side.

For example, when a guide is provided on the rear surface of the upper body, the slider is coupled to one side of the front surface of the lower body in contact with the slider to reciprocate and slide together.

1 is a plan view showing a rear surface of a conventional slide type mobile communication terminal. The upper body 10 provided with a display screen (not shown) on the front side and the lower body 20 coupled with the battery pack 21 on the rear side are stacked in parallel with each other to open or close by reciprocating sliding movement in the horizontal direction. A guide slit 11 is formed on a rear surface of the upper body 10 and a guide (not shown) is provided for guiding sliding therein, and a slider for reciprocating sliding along the guide is formed of the lower body 20. It is fastened to one side of the front and slides together with the lower body 20.

Here, an elastic means such as a coil spring or a spring is provided between the guide 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 means, the elastic fixing means is provided so that the upper body and the lower body can be temporarily fixed in the closed state and the open state. When the above force is applied, the fixing is released to allow movement by the restoring force of the elastic means.

Such guides, sliders, elastic means and elastic fixing means are usually provided as one module. Hereinafter, the structure and problems of the conventional semi-automatic slide module will be described.

2 is a detailed view illustrating a slide module of a conventional slide type mobile communication terminal. (a) shows the front surface of the slide module 100, (b) shows the rear surface thereof, and (c) shows the elastic fixing means 122 and the elastic means of the slider 120 in detail. The slide module 100 is connected to a guide rail 110 for guiding sliding, a slider 120 for reciprocating sliding along the guide rail 110, and one end of the guide rail 110 from the slider 120. And a coil spring 126 providing restoring force.

Fixing grooves 112 and 113 for temporarily fixing the slider 120 are formed at both ends of the bottom of the guide rail 110, respectively, and the slider 120 is a pressure spring 123 and the pressure spring 123. It is provided with an elastic fixing means 122 including a fixing ball 124, a portion of which is pushed out of the housing by.

The slider 120 may be temporarily fixed by the fixing ball 124 caught in the fixing groove 112 of one side in a state of receiving a restoring force by the tensioned coil spring 126, the force of a predetermined size or more in the sliding direction When receiving, the pressing spring 123 for pressing the fixing ball 124 is compressed while sliding is released until the fixing is fixed to the opposite side fixing groove 113.

However, when the pressing force of the pressure spring 123 in the elastic fixing means 122 is increased, the magnitude of the force required when the user attempts to open or close 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 pressure spring 123 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.

In addition, even if an appropriate pressure spring 123 is used, the user has to give a force of a predetermined size or more, and thus the ease of use decreases, and the contact surface between the fixing ball 124 and the fixing grooves 112 and 113 wears as the fixing and release are repeated. Or there exists a problem that it is easy to deform | transform and cannot maintain the reliability of a fixing operation.

Accordingly, the present invention has been proposed to solve the above problems, the terminal is fixed in a fully closed and open state stably, semi-automatically to open or close by sliding itself in the remaining sections if you move the terminal a little manually Its purpose is to provide a mobile communication terminal having a sliding structure.

In order to achieve the object of the present invention, the semi-automatic slide type mobile communication terminal using the cross-sectional cam according to the present invention includes a slide type mobile communication in which an upper body and a lower body are stacked, and one side is slid to the other side within a predetermined section. A terminal, comprising: a cross-section cam seated in a receiving groove on an upper surface of a lower body, and having a lower cam pressurized upward by a spring and an upper cam which rotates semi-automatically by a predetermined cam motion between the lower cam; And one end is rotatably connected to one side of the bottom of the upper body, the other end includes a link rotatably connected to the crank portion extending from the upper cam.

In this case, it is preferable to separately provide a slide module similar to the conventional manual slide type mobile communication terminal for the basic slide operation of the upper body and the lower body.

Unlike this, a guide rail vertically formed on the upper surface of the lower body by a slide section; A slider fixed to the bottom of the upper body and vertically sliding in the sliding guide; A cross-section cam seated in a receiving groove on an upper surface of the lower body, and having a lower cam pushed upward by the spring and an upper cam which rotates semi-automatically by a predetermined cam motion of the lower cam; And one end rotatably connected to the slider and the other end rotatably connected to one side end of the upper cam, so that the sliding operation can be performed automatically without a separate slide module. Of course, it is also possible to implement a separate slide module to ensure reliability.

In both the former and the latter, the cross-sectional cam is a cylindrical receiving groove formed in the upper center of the upper surface of the lower body; A spring supported by the bottom of the receiving groove; A lower cam pressurized upward by the spring, the rotational movement of which is limited to only the vertical movement, and a cam profile having a predetermined curvature on the upper surface; And an upper cam having a cam contour corresponding to the cam contour of the lower cam on a lower surface thereof, the vertical movement being limited to allow only a rotational movement, and an upper cam having a crank portion extending in a radial direction on an upper portion thereof. The cross section cam is temporarily fixed by engaging the cam cross section of the upper cam and the lower cam when the slide type mobile communication terminal is completely closed or open, and after the upper cam is rotated by a predetermined angle or more by the external force. Is semi-automatically rotated by the repulsive force of the spring until it is fully opened or closed.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

Figure 3a is a front view showing the lower body of the mobile communication terminal open state according to the present invention. In this embodiment, a guide rail 201 is vertically formed by a slide section on an upper side of the lower main body 200 provided with a plurality of input keys 220, and slides vertically in the guide rail 201 and the upper main body. A slider 202 is fixedly connected to the bottom of the (not shown). The guide rail 201 may be formed integrally with the lower body case, or may be provided as a separate module.

The center portion of the lower main body 200 is provided with a crank portion 204 to rotate about one axis, the one end is connected to the slider 202 rotatably 203, the other end thereof is the crank portion 204 It is also rotatably connected to the distal end of.

A separate slide module 211 may be provided on the upper surface of the lower body 200 or the lower surface of the upper body (not shown). Sliding operation of the upper body and the lower body may be made by the guide rail 201 and the slider 202, a separate slide module 211 may be added to increase the reliability, such as durability of the product.

As another embodiment, although not shown in the figure, the sliding operation is performed by the conventional slide module 211, and unlike the above-described embodiment, one end of the link is not required to form the guide rail 201 on the lower body. The same function can be performed by being rotatably connected to one side of the bottom of the upper body (not shown).

Figure 3b is a front view showing the lower body of the mobile communication terminal closed state according to the present invention. An upper body (not shown) is slid downward from the state shown in FIG. 3A to show the lower body 200 in a state in which the terminal is closed.

When the upper body slides down, the slider 202 fixedly connected to the upper body moves downward along the guide rail 201, which is transmitted to the crank part 204 through the link 203 and the crank part ( 204 is rotated by a predetermined angle.

On the contrary, when the crank part 204 is rotated for some reason, the rotational motion is transmitted to the slider 202 through the crank part 204 and the link 203, and eventually the upper body (not shown) is moved up and down. You can move it.

In yet another embodiment described above, the linear motion of the upper body rotates the crank portion 204, while the rotational movement of the crank portion 204 linearly moves the upper body through the link 203.

A cylindrical accommodating groove is formed in the center of the upper surface of the lower main body 200, and the accommodating groove is pressurized upward by the spring 207 supported by the bottom and the spring 207, and only vertical movement is possible. Rotational movement is limited so that the lower cam 206 has a cam contour having a predetermined curvature on the upper surface, and a cam contour corresponding to the cam contour of the lower cam is formed on the lower surface and the vertical movement is limited so that only the rotational movement is possible. An upper cam 205 having a crank portion 204 extending in a radial direction is inserted into the upper portion thereof.

The lower cam 206 having a cylindrical shape may be allowed to move up and down only by being engaged with the inner wall of the receiving groove by a longitudinal groove and a protruding piece (not shown), and the rotational movement may be limited. 205 is a rotational groove is allowed only by the grooves and protrusions (not shown) formed on the outer circumferential surface thereof (not shown) or by an axial bolt (not shown) for fixing the entire section cam to the receiving portion, and the vertical movement is limited. Can be.

The cross section cam is temporarily fixed by engaging the cam cross section of the upper cam 205 and the lower cam 206 when the terminal is completely closed or opened, the upper cam 205 is a certain angle or more by an external force After being rotated, the terminal is semi-automatically rotated by the repulsive force of the spring 207 until the terminal is completely opened or closed to complete the operation of opening or closing the upper body connected through the crank part 204 and the link 203. Make sure

The operation principle of the semi-automatic slide type mobile communication terminal using the cross section cam is as follows.

When the user pushes or pulls the upper body slightly by hand, the upper cam 205 rotates through the link 203 and the crank part 204, and the lower cam 206 with limited rotation is along the cam profile. The spring 207 is compressed to move downward, that is, inside the receiving groove. After passing through the critical point of the cam contour in this process, the lower cam 206 is pushed up by the repulsive force of the compressed spring 207 even if the user does not apply the force, thus the upper cam 205 is limited to the vertical movement Rotates along the cam contour. The upper body (not shown) is semi-automatically opened or closed by the link 203 in accordance with the rotational movement of the crank part 204 extending from the upper cam 205.

Accordingly, the semi-automatic slide type mobile communication terminal using the cross-sectional cam according to the present invention uses a cross-sectional cam including a lower cam moving up and down and an upper cam rotated in a predetermined section by a linear motion of the lower cam. By connecting the rotational motion of the cam with the main body of the terminal reciprocating sliding using the crank part and the link can be semi-automatic sliding.
