In addition, the gear unit is characterized in that any one of the planetary gear, transmission gear, gearbox.

In addition, the electronic device is characterized in that any one of a mobile phone, a notebook, a smart phone.

The sliding device and the electronic device having the same according to the present invention have an effect of increasing convenience of use because the keypad is exposed to the outside from the main body at the same time as the display unit is opened.

In addition, since the keypad according to the present invention is located inside the main body and is exposed to the outside of the main body only when used, there is an effect of preventing foreign matter and dust from being attached to the keypad.

1 is a perspective view schematically showing an electronic device having a sliding device according to the present invention.
2 is a cross-sectional view schematically showing an electronic device having a sliding device according to the present invention.
3 is an enlarged perspective view schematically showing a sliding device according to the present invention.
4 to 5 are views for explaining the operation of the electronic device having a sliding device according to the present invention.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

1 shows an electronic device employing a sliding device according to the present invention.

As shown in FIG. 1 and FIG. 2, the electronic device 1 includes a main body 10, a display unit 20, and a keypad 30.

The main body 10 includes an accommodating portion 11 in which a portion of the upper surface is recessed, and a space portion 13 recessed in an inward direction on the front surface.

The display unit 20 is accommodated in the accommodating part 11 of the main body 10, and both lower ends thereof are hinged to one side of the accommodating part 11.

A liquid crystal 21 for displaying an image is provided on the front of the display unit 20.

An input unit including a plurality of buttons 31 on which various characters and symbols are displayed is provided on the upper surface of the keypad 30 (see FIG. 5) and is accommodated in the space 13 provided in the main body 10.

In addition, the keypad 30 is slidably moved in the front-rear direction of the space 13 by the sliding device 40 described later.

At this time, the display support portion 12 is provided above the space portion 13 of the main body 10 to protect the liquid crystal 21 of the display portion 20 from external impact.

As shown in FIG. 2, the sliding device 40 allows the keypad 30 to be pulled out in front of the main body 10 in conjunction with the upward rotation of the display unit 20.

In addition, the sliding device 40 allows the keypad 30 to be introduced into the space 13 of the main body 10 in conjunction with the downward rotation of the display unit 20.

2 to 5 show a sliding device 40 according to the invention.

The sliding device 40 includes a shaft 41a projecting outwardly at both lower ends of the display unit 20, a first gear 41 connected to the shaft 41a, and a second coupler coupled to the first gear 41. And a third gear 43 connected to the gear 42 and the second gear 42.

In addition, the rack gear 44 meshes with the third gear 43 to allow the keypad 30 to slide in and out of the main body 10.

A gear unit for increasing the rotation of the first gear 41 is provided between the first gear 41 and the rack gear 44, and the gear unit may be any one of a planetary gear, a gear shift, and a gear. .

In the present embodiment, the gear unit includes the second gear 42 and the third gear 43.
