It relates to a sliding type mobile terminal that can prevent the call is disconnected down).

Recently, sliding type mobile terminals, which have become mainstream in the use of new phones, are divided into manual and semi-automatic methods.

The manual method is relatively inconvenient because all of the up / down operations for the cover part in which the liquid crystal is formed can only be performed by a user's manual operation.

On the contrary, the semi-automatic method has a driving principle of sliding by spring tension above or below a certain stroke by adding a mechanism using a spring to the manual hinge module. Therefore, in the case of the semi-automatic method, if only a partial section of the stroke is manually operated, the remaining sections have the convenience of an operation of being automatically up / down by the spring. Therefore, the preference of the semi-automatic sliding type mobile terminal is high.

However, in the conventional sliding type mobile terminal, there is a problem that the cover is arbitrarily down because of an external factor or a magnetic mistake during a call while the cover is up.

In particular, when a mobile terminal is mounted using a shoulder and a head in a situation where a mobile terminal cannot be gripped by hands during work, such a problem is likely to occur.

It is an object of the present invention, the user can selectively maintain the position of the cover (Up) state of the cover (Up) to prevent the phenomenon that the cover is arbitrarily down (call down) due to external factors or magnetic mistakes, etc. It is to provide a sliding type mobile terminal.

The object may include: a main body provided with an input key on at least one side; A cover part which has a liquid crystal on which a screen is formed and is operable to slide up / down with respect to the main body part; And when the cover portion is up (Up) relative to the main body portion, it is achieved by a sliding type mobile terminal including a position holding portion for maintaining the position of the cover portion at the corresponding position.

Here, the position holding portion, the position holding groove formed in any one of the main body portion and the cover portion; And a position holding protrusion provided on the other portion and a portion of which is selectively inserted into the position holding groove.

The position holding projection portion is in contact with the projection groove formed on the upper surface of the main body portion is movable toward the position holding groove, the end portion is coupled to the position holding groove selectively; And a handle portion protruding upward from one surface of the coupling portion.

The projection groove portion may be further formed with a stopper for preventing the separation of the position holding projection portion.

The position holding groove is provided on the cover portion side.

And a hinge module having a fixed part fixed to the main body, a slider coupled to the cover part and slidably movable relative to the fixed part, and an elastic member provided between the fixed part and the slider. A retaining groove is formed in the slider.

The position holding groove may be formed by a through hole penetrating the plate surface.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In the description of each embodiment, the same reference numerals are given to the same configurations.

1 and 2 are perspective views showing a sliding up / down operation of the cover unit with respect to the main body in the sliding type mobile terminal according to the present invention, respectively.

As shown in these figures, the sliding type mobile terminal 1 according to the present invention largely has a main body portion 10 and a cover portion 20 which is movable relative to the main body portion 10.

An input key 12 is provided at one side of the main body 10. The input key 12 adjusts the volume and key tone, including the role of inputting a telephone number or a letter. Below the input key 12, a transmitter 14 for transmitting a user's voice to the other party or recording a voice message is formed.

Of course, in addition to this, a side key (not shown), an antenna, and other accessories may be further provided, which will be omitted. If necessary, a number of techniques filed by the applicant will be cited.

1 is a state in which the cover unit 20 is down because the mobile terminal 1 is not used, and FIG. 2 shows the cover unit 20 in order to use the mobile terminal 1. And the input key 12 area of the main body 10 is opened.

As such, in order to move the cover part 20 from FIG. 1 to FIG. 2, the cover part 20 is pushed upward with respect to the main body part 10. In this case, the hinge module 30 provided therebetween operates. .

3 and 4 are views of the hinge module corresponding to FIGS. 1 and 2, respectively, and FIG. 5 is a schematic cross-sectional view taken along line AA ′ of FIG. 4.

As shown in these figures, the hinge module 30 has a fixed portion 31 fixed to the main body portion 10 and a slider 32 coupled to the cover portion 20 and slidably movable relative to the fixed portion 31. ) And an elastic member 33 provided between the fixing part 31 and the slider 32.

The elastic member 33 is provided to impart the moving elastic force of the slider 32 with respect to the fixing portion 31. To this end, both ends of the elastic member 33 is fixed to brackets (not shown), respectively, to the fixing part 31 and the slider 32, respectively.

The elastic member 33 repulses by its tension above or below a predetermined stroke to drive the slider 32. Therefore, if the user manually manipulates only a part of the stroke, that is, if the cover part 20 is pushed up a little, the remaining part is automatically up / down by the elastic member 33.

While the slider 32 is formed in a nearly straight shape, an end portion of the fixing part 31 is provided with a Korean letter “c” shaped rail portion 31a for slidably supporting both ends of the slider 32. Thus, the slider 32 makes rail movement with respect to the fixing part 31.

On the other hand, as described above, the operation of the hinge module 30 as shown in Figure 4 by the operation of the sliding portion (Up) of the cover portion 20 as shown in Figure 2 during the call, external factors or magnetic Due to a mistake, the cover part 20 may be arbitrarily down and the call may be disconnected.

This is particularly severe when the mobile terminal 1 is mounted using the shoulder and head in a situation in which the mobile terminal 1 cannot be gripped by hand during work and makes a call.

Therefore, the means which can hold | maintain the position of the state in which the cover part 20 was slid up (up) is calculated | required. This is maintained by the position maintaining unit 40.
