It is disposed between the 50 and the fixed plate 40 is provided with a slide cam 70 for maintaining the upper body 20 in a moved state by the elastic restoring force of the elastic member 60.

The fixing plate 40 is mounted on the upper end of the upper surface of the lower body 10 through screws, and on both sides thereof, a pair of channels 41L and 41R are opposed to each other in the vertical direction. The fixed plate 40 is made of a metal plate, both edges are firmly mounted on the upper surface of the lower body 10 through the screws.

And the movable plate 50 is mounted on the lower surface of the upper body 20 through the screws, the both sides of the guide projection 51L in the longitudinal direction to be coupled to the channel 41L (41R) of the fixed plate 40, respectively ( 51R) are made opposite. Accordingly, the movable plate 50 slides up and down along the channels 41L and 41R (see arrow B direction in FIG. 8). The movable plate 50 is also made of a metal plate, and an edge thereof is formed through a screw. It is firmly mounted on the lower surface of the upper body 20. In addition, a cam curved surface 52 is formed in one side of the movable plate 50 in the longitudinal direction. The cam curved surface 52 is integrally processed on one side of the movable plate 50 provided with the guide protrusion 51R, and the central portion 52a is convex, and the inclined surfaces 52b and 52c inclined outwardly toward the upper and lower sides. It consists of.

On the other hand, the slide cam 70 is arranged to move left and right on the front surface of the fixed plate 40, the upper body 20 is configured to move in contact with the cam curved surface 52 in the process of raising or lowering. The detailed structure thereof is as follows.

First, the slide cam 70 is disposed on the front surface of the fixed plate 40, the rails 71a and 71b are provided along the upper and lower ends, and the protrusions 72 are formed to contact the cam curved surfaces 52 at the side ends. It consists of a metal plate.

In order to guide the horizontal movement of the slide cam 70 horizontally, the guide members 73a and 73b are coupled to the upper and lower sides of the fixed plate 40 so that the rails 71a and 71b of the slide cam 70 can be relaxed. It is prepared. Accordingly, the slide cam 40 is moved horizontally and horizontally through the guide members 73a and 73b of the fixed plate 40 (see arrow A direction in FIG. 8), and the protrusion of the slide cam 70 is 72 moves while abutting with the cam curved surface 52.

In addition, an elastic member 60 for elastically supporting the slide cam 70 in one direction of the movable plate 50 (the cam curved surface 52 side) is provided, so that the protruding portion 72 of the slide cam 70 is the cam curved surface. It will remain in contact with 52 at all times. One end of the elastic member 60 is fixed via the fixing block 42 on the fixing plate 40 side, and the other end is formed of the torsion springs 61 and 62 fixed to the slide cam 70.

In the embodiment of the present invention, the torsion springs 61 and 62 are disposed in a pair so as to face up and down between the fixed plate 40 and the slide cam 70, and the center portion is wound in a coil to exhibit elastic restoring force. And, one end thereof is fixedly supported by the fixed block 42 fixed to the fixed plate 40 and the other end thereof is fixed to the slide cam (70). To this end, the fixing hole 73 is drilled in the slide cam 70 so that the end portions of the torsion springs 61 and 62 are fitted to each other.

Therefore, when the upper body 20 is lowered more than half, the upper body 20 together with the movable plate 50 is maintained in the lower state due to the elastic restoring force of the torsion springs 61 and 62, and in this state When the upper body 20 is raised to the upper side by more than half again, the upper body 20 together with the movable plate 50 is lowered to the lower side by the elastic restoring force of the torsion springs 61 and 62.

Next, the operation of the slide assembly for a mobile phone according to the present invention configured as described above and the effects thereof will be described.

First, in a state where the upper main body 20 descends to the maximum and is aligned with the lower main body 10, as shown in FIG. 4, the upper main body 20 is maintained in a state of completely covering the upper lower main body 10. . Therefore, the keypads 11 of the lower body 10 are not exposed to the outside, only the liquid crystal display 21 of the upper body 20 is exposed to the outside.

As shown in FIG. 8, the protrusion 72 of the slide cam 70 is held and supported by the top end of the cam curved surface 52, so that the upper body 20 does not slide without applying an artificial force. That is, since the protrusion 72 of the slide cam 70 is seated on the top of the cam curved surface 52 by the elastic support force of the torsion springs 61 and 62, the upper body 20 is matched with the lower body 10. Will remain intact.

When the user pushes the upper body 20 upward in order to make a call in this state (see FIG. 5), the moving plate 50 mounted on the upper body 20 is connected to the channel 41L of the fixed plate 40 ( 41R) and slides upward (see FIGS. 9 and 10). At this time, until the projection 72 of the slide cam 70 reaches the center portion 52a of the cam curved surface 52, the torsion springs 61 and 62 are elastically deformed to have a strong restoring force.

Subsequently, when the upper body 20 rises more than half, the movable plate 50 with the upper body 20 naturally slides upward due to the elastic restoring force of the torsion springs 61 and 62. The upward sliding of the upper body 20 proceeds until the protrusion 72 of the slide cam 70 reaches the bottom end of the lower inclined surface 52c of the cam curved surface 52 (see FIG. 11).

That is, as shown in Figure 11, when the upper body 20 is moved to the upper side as the torsion spring 61, 62 is elastically restored, the projection 72 of the slide cam 70 is the lower side of the cam curved surface 52 It is located at the lowest end of the inclined surface 52c, whereby the upper body 20 is fixed in a moved state. In addition, even when the upper body 20 is raised to the maximum, the movable plate 50 is coupled to the channels 41L and 41R of the fixed plate 40, and the slide cam 70 is in contact with the cam curved surface 72. Maintained in a state, the upper body 20 is more firmly fixed position.

As a result, the upper body 20 is maintained in a raised state from the lower body 10 and at the same time the keypad 11 of the lower body 10 is exposed to the outside to make a call or receive an incoming call (FIG. 5). Reference).

On the other hand, after finishing the call, when the user pushes the upper body 20 downward, the slide cam 70 moves horizontally along the cam curved surface 52 while winning the elastic force of the torsion springs 61 and 62. .

At this time, when the protrusion 72 of the slide cam 70 is out of the center portion 52a of the cam curved surface 52, the lower body slides downward of the upper body 20 by the elastic restoring force of the torsion springs 61 and 62. Proceeds naturally until it is caught by the upper end of the upper inclined surface 52b of the cam curved surface 52. Therefore, the upper body 20 is maintained in a state of being matched to the lower body 10, the keypad 11 is not visible.

As described in detail above; According to the slide assembly for a mobile phone according to the present invention, the coupling state of the upper body and the lower body through the channel of the fixed plate during the vertical sliding operation of the upper body is maintained firmly and in the left and right and up and down directions by the elastic support of the slide cam There is an effect that the clearance of the effectively prevented.

In addition, since the elastically supported slide cam moves the cam during the sliding operation of the upper body, the upper body moves more stably, and the elastic restoring force of the slide cam is maintained even after long-term use, resulting in superior product reliability. There is an advantage.
