Description

Sliding apparatus for mobile phone

The present invention relates to a sliding device for a mobile phone, and more particularly to a sliding device for a mobile phone with improved assembly.

In general, a mobile phone has a bar type, a flip type, a folder type, a slide type, etc. according to the appearance and location of the handset. In the early stages of the launch of mobile phones, the bar and flip-types became the mainstream, but now the display and the folding type are mainstream as various display functions and miniaturization are required.

In particular, the slide-type mobile phone consists of a lower body to which the operation button is mounted and an upper body to which the display window is installed and slidably interlock with the lower body. Compared to the clamshell type, it is more convenient to operate and the display window is exposed to the outside.

Due to these various advantages, the demand for slide-type mobile phones continues to increase, and various models are continuously released. In addition, the development of a sliding device for sliding the upper body and the lower body to each other has been made steadily.

The torsion spring 30 can be easily assembled to the guide member 10 and the slide member 20 by fitting the respective coupling holes 31a, 32a, 33a into the respective coupling shafts 14, 15 and 25. have.

Sliding device according to a preferred embodiment of the present invention made in such a configuration, as shown in Figure 2, is installed in the mobile phone to support the upper body 40 and the lower body 50 of the mobile phone so as to be mutually sliding. Slide member 20 is coupled to the lower body 50, the guide member 10 is coupled to the upper body (40).

Hereinafter, the operation of the sliding device for a mobile phone according to a preferred embodiment of the present invention will be described with reference to Figures 3a to 3c.

As shown in FIG. 3A, the slide member 20 is positioned above the guide member 10 at an initial position where no external force is applied. In this position, the torsion spring 30 is in an undeformed or somewhat deformed initial state, and the angle made by a portion of the torsion spring 30 around each bending part 34, 35, 36 is also an initial state. . At this time, the upper body 40 (see Fig. 2) of the mobile phone is in a state covering the front portion of the lower body 50 (see Fig. 2).

As shown in FIG. 3B, when the slide member 20 or the guide member 10 is subjected to an external force and the slide member 20 is positioned at approximately the middle portion of the guide member 10, the first bending portion 34 is shown. The angle formed by the partial portion of the torsion spring 30 with respect to) is also maximized, and the angle formed by the partial portion of the torsion spring 30 with respect to the second and third bending portions 35 and 36 is The minimum amount of deformation of the torsion spring 30 becomes maximum. At this time, the slide member 20 is in a state that can be pushed in the upper direction or the lower direction of the guide member 10 by the elastic restoring force of the torsion spring (30).

In this state, when the guide member 10 or the slide member 20 receives an external force so that the relative position of the slide member 20 with respect to the guide member 10 is biased downward, the torsion spring 30 is in an initial state. The torsion spring 30 presses the slide member 20 toward the lower direction of the guide member 10 while elastically restoring the elastic member.

Accordingly, the slide member 20 slides downward along the guide bars 11 and 12 of the guide member 10, and as shown in FIG. 3C, the torsion spring 30 is returned to the initial state. . When the slide member 20 slides to the lower portion of the guide member 10 and stops, the upper body 40 of the mobile phone is raised to the upper portion of the lower body 50, as shown in FIG.

In this way, the torsion spring 30 at the position where the upper body 40 of the mobile phone is raised from the lower body 50 prevents the upper body 40 from lowering down the lower body 50. Support the body 40.

According to the present invention described above, since the torsion spring for pushing the sliding member coupled to the guide member is provided with only one bent several times, the torsion spring can be easily coupled to the guide member and the sliding member, thereby sliding The assemblability of the device can be improved.

The present invention described above is not limited to the configuration and operation as illustrated and described. That is, the sliding device for a mobile phone according to the present invention can be variously changed and modified within the spirit and scope of the utility model registration claims described.
