It is to be opened by the elastic restoring force beyond the critical point. Since the structure of the cam member 156 is already known, a detailed description thereof will be omitted.

The first cam 156a of the cam member 156 is coupled to the second rotary link 150, and the housing in which the second cam 156b is accommodated is installed in the cover 160.

One end of the cover 160 is coupled via the second rotary link 150 and the cam member 156, and the other end is coupled to the slide groove 118 provided in the base bracket 110 through the shaft pin 161. . In addition, the cover 160 has an outer shape of an arc provided on a concentric circle with the guide link 130 and the first and second

rotary links

140 and 150.

Then, the operation of the rotary slide device and the electronic device having the same according to the present embodiment having the above configuration will be described with reference to FIGS. 4 to 6.

4 and 6 are each side view of the rotary slide device according to the embodiment when the sealing and opening of the slide, Figure 5 is to explain in more detail the operation of the guide link and the first and second rotary links and the cover of the rotary slide device Schematic for.

As shown in FIG. 4 and FIG. 5A, only the cover 160 is exposed to the outside in a state where the first member 1 and the second member 2 overlap (close). In addition, one end 141 of the first rotary link 140 protrudes from the basket 134 of the guide link 130 to the inside of the cover 160 and the slit 142 of the first rotary link 140. The side wall 152 of the second rotary link 150 coupled to the protrudes from one end 141 of the first rotary link 140.

When an external force is applied in this state, the second member 2 rotates about the basket portion 134 of the guide link 130, and at this time, the first rotary link 140 provided on the concentric circle with the guide link 130. ) And the second rotary link 150 also starts to rotate as shown in FIG. For example, a portion 141 of the first rotary link 140 moves into the basket 134 of the guide link 130, and similarly, the side wall 152 of the second rotary link 150 also includes the first rotary link ( It moves into the first rotary link 140 along the slit of 140.

Meanwhile, the cam member 156 also rotates in accordance with the rotation of the second rotary link 150. Since the cam member 156 is coupled to one end of the cover 160, the other end pin 161 coupled to the slide groove 118 of the base bracket 110 is also provided on the concentric circle with the second rotary link 150. Move along the first slide groove 118a of the slide groove 118.

At this time, if the external force applied to the cam member 156 does not exceed the elastic threshold values of the first cam 156a and the second cam 156b, the second member 2 overlaps with the first member 1. On the contrary, if the threshold value is exceeded, the second member 2 continues the opening operation by the elastic restoring force even if the external force is removed.

5C illustrates a state in which the cam member 156 continues to rotate by the elastic restoring force. Since the guide link 130, the first rotary link 140 and the second rotary link 150 rotates around the center of the guide link 130, connecting the second rotary link 150 and the cover 160 The shaft pin 161 provided at the other end of the cam member 156 and the cover 160 should also rotate about the center of the guide link 130. However, if the other end of the cover 160 rotates around the center of the guide link 130, the position of the shaft pin 161 at the time of rotational opening can only be exposed out of the first member 1.

In order to prevent this, the shaft pin 161 of the cover 160 moves along the second slide groove 118a of the slide groove 118 when the cam member 156 rotates, and rotates the rotation direction inward of the first member 1. Switch to This is because the distance between one end of the cover 160 (cam member 156) and the other end (shaft pin 161) is constant, so that the other end along the rotating end is forced to retreat to the inside of the first member 1.

5D and 6 illustrate a state in which the second member 2 is completely opened with respect to the first member 1. As shown in the drawing, when the second member 2 is fully opened, the first rotary link 140 and the second rotary link 150 overlap each other and overlap the inside of the basket 134 of the guide link 130. The shaft pin 161 is positioned at the end of the second slide groove 118b of the slide groove 118. In this position, since the cover 160 is drawn into the inside of the first member 1, the upper and lower ends of the first member 1 and the second member 2 are in close contact with each other. It is not exposed to and the appearance is beautiful.
