Between the first body 210 and the second body 220, a sliding device 100 for a mobile device of the present embodiment described below is installed to slide the second body 220 with respect to the first body 210. To be supported.

3 to 6 are plan views illustrating operating states of the sliding device 100 for a portable device installed in the portable device 200 shown in FIG. 1, respectively. Referring to FIG. 3, the sliding device 100 for a portable device of the present embodiment includes a base member 10 and a slide member 20.

The base member 10 is coupled to the first body 210 and the slide member 20 is coupled to the second body 220. The slide member 20 is slidably mounted to the base member 10. That is, the base member 10 includes a guide groove 12 for receiving both edges of the slide, and the slide member 20 is fitted to the base member 10 by using the guide groove 12. The guide groove 12 is provided with a lubrication member to reduce the friction between the guide groove 12 and the slide member 20, thereby smoothly sliding the slide member 20 relative to the base member 10.

The first elastic means 30 and the third elastic means 80 are installed between the base member 10 and the slide member 20.

The first elastic means 30 is a first frame 32 rotatably coupled to the base member 10, a second frame 34 rotatably coupled to the slide member 20, both ends of the first frame And five springs 36 fixed to the second frame 34 and the second frame 34, respectively. The first elastic means 30 is in a direction in which the first frame 32 and the second frame 34 come closer by springs 36 fixed between the first frame 32 and the second frame 34. Provide elastic force. As a result, the elastic force is continuously provided in the direction in which the portable device opens.

The third elastic means 80 is the same as the first elastic means 30 in that one end is rotatably coupled to the base member 10 and the other end is rotatably coupled to the slide member 20. However, unlike the first elastic means 30, the third elastic means 80 provides elastic force in a direction in which both ends coupled to the base member 10 and the slide member 20 are far from each other.

The rotating piece 40 is rotatably installed in the slide member 20. The rotating piece 40 has a cam pin 44 formed to be spaced apart from the rotation center 42 thereof. The second elastic means 50 is coupled to the free end of the rotating piece 40, and the other end of the second elastic means 50 is coupled to the slide member 20.

The second elastic means 50 provides an elastic force to the rotation piece 40 so that the extension line connecting the rotation center 42 and the cam pin 44 of the rotation piece 40 is maintained in parallel with the sliding direction. That is, when the cam pin 44 of the rotation piece 40 is parallel to the sliding direction and is out of the cam reference line 46 which is an extension line passing through the rotation center 42 of the rotation piece 40, the cam pin 44 is returned to the cam reference line 46 again. Provide elastic force.

The base member 10 is provided with a cam 60. The cam 60 includes a first inclined cam portion 62, a second inclined cam portion 64, and a locking groove 66. The first inclined cam portion 62 provides an inclined surface such that the cam pin 44 slides away from the cam reference line 46 when the slide member 20 moves in the open direction with respect to the base member 10. The second inclined cam portion 64 is inclined so that the cam pin 44 slides away from the first direction with respect to the cam reference line 46 when the slide member 20 moves in the closing direction with respect to the base member 10. To provide. The locking groove 66 is formed between the first inclined cam portion 62 and the second inclined cam portion 64. The locking groove 66 is inserted into and fixed to the cam pin 44 slid along the second inclined cam portion 64.

The path guide member 70 is installed at a position spaced apart from the locking groove 66 by a predetermined interval. The locking groove 66 and the path guide member 70 are spaced apart at an interval enough to allow the cam pin 44 to pass therethrough. The path guide member 70 serves to prevent the cam pin 44 passing past the second slope cam portion 64 from moving past the locking groove 66.

The stopper 90 is provided in the upper part of the rotation center 42 of the rotating piece 40 of the slide member 20. The spoiler moves along the guide slit 14 formed in the base member 10. The stopper 90 has a moving range limited by both ends of the guide slit 14.

Hereinafter, with reference to the accompanying drawings will be described the operation of the sliding device 100 and the portable device 200 for a portable device according to an embodiment of the present invention.

3 illustrates a closed state of the sliding device 100 for a portable device of the present embodiment, in which the portable device 200 having the same is as shown in FIG. 1. When the user slightly pulls the second body 220 in the closing direction (A) in such a state, as shown in FIG. 4, the cam pin 44 held in the locking groove 66 of the cam is locked by the locking groove 66. It exits from, and is positioned on the cam reference line 46 by the second elastic means (50). When further pulled back, the stopper 90 is caught by the lower end of the slide slit 14 to limit the movement of the slide member 20. At this time, the first elastic means 30 and the third elastic means 80 slightly rotates in the counterclockwise direction. The springs 36 between the first frame 32 and the second frame 34 of the first elastic means 30 are pulled in the direction in which the first frame 32 and the second frame 34 are close to each other. As a result, an elastic force is applied so that the slide member 20 slides in the opening direction. The direction of the elastic force applied by the first elastic means 30 is maintained in the same direction.

Next, when the user releases the second body 220, the slave member automatically moves in the opening direction as shown in FIG. At this time, the portable device 200 is in the state shown in FIG. 2. This process proceeds as follows.

When the user releases the second body 220, the cam pin 44 rises along the cam reference line 46 and then contacts the first inclined cam portion 62 of the cam 60 from the cam reference line 46 in the first direction. Away When the cam pin 44 is out of the cam 60, it rises again along the cam reference line 46. At this time, the first elastic means 30 and the second elastic means 50 is rotated in the clockwise direction, the first elastic means 30 exerts an elastic force in the opening direction, the third elastic means 80 in the closing direction Apply elastic force. Since the elastic force of the first elastic means 30 is designed to be stronger, the slide member 20 slides in the opening direction.

When the slide member 20 slides to some extent in the opening direction, it is in a state as shown in FIG. 5, and the third elastic means 80 is in a state of not providing an elastic force in the opening direction or the closing direction. When the sliding in the opening direction is further progressed, the third elastic means 80 is rotated as shown in FIG. 6 to apply an elastic force to the opening direction. The first elastic means 30 is reduced in length, so that it is difficult to apply sufficient elastic force in the opening direction anymore, but the third elastic means 80 provides sufficient elastic force in the opening direction and continues to have sufficient elastic force in the opening direction. The advantage is that it can be added.

In the open state as shown in FIGS. 6 and 2, when the user pushes the second body 220 in the closing direction B, the cam pin 44 is lowered along the cam reference line 46 and then the second of the cam 60 is moved. While in contact with the inclined cam portion 64, it moves away from the cam reference line 46 in the direction opposite to the first direction. If it continues to push in the closing direction (B), the cam pin 44 is inserted into the locking groove 66 of the cam 60 is fixed. The path guide member 70 spaced below the locking groove 66 serves to prevent the cam pin 44 from passing through the locking groove 66. At this time, the first elastic means 30 and the third elastic means 80 rotates in the counterclockwise direction.

As mentioned above, although an embodiment of the present invention has been described, the present invention is not limited to the above described and illustrated form.

For example, in the present embodiment, the second elastic means 50 is installed on the cam reference line 46 so that the cam pin 44 of the rotating piece 40 returns to the cam reference line 46. It is also possible to apply the elastic force in both directions about the pivoting piece 40 to return to the cam reference line 46.

Meanwhile, the portable device sliding device of the present embodiment and a portable device having the same have been described as an example, but the portable device sliding device of the present invention may be manufactured and flown without being installed in the portable device. Even if the manufacturer of the device purchases and uses it, it is within the scope of the right.
