Abstract

A terminal wireless charging cradle may comprise a body disposed horizontally, a recess formed to be stepped downward from an upper surface of the body, a supporter having a wireless charging circuit built therein and movable between a first position laid down in the recess and a second position erected to protrude upward from the recess, a pair of guide grooves formed in both inner surfaces of the recess, and a plurality of protrusions protruding from both lower sides of the supporter into the pair of guide grooves and sliding along the pair of guide grooves when the supporter moves.

Claims (51)

1 . A terminal wireless charging cradle comprising:

a body disposed horizontally;

a recess formed to be stepped downward from an upper surface of the body;

a supporter having a wireless charging circuit built therein and movable between a first position laid down in the recess and a second position erected to protrude upward from the recess;

a pair of guide grooves formed in both inner surfaces of the recess; and

a plurality of protrusions protruding from both lower sides of the supporter into the pair of guide grooves and sliding along the pair of guide grooves when the supporter moves.

2 . The terminal wireless charging cradle of claim 1 , wherein each of the pair of guide grooves comprises:

a first groove extending horizontally; and

a second groove extending in an inclined direction toward the front from a front end of the first groove toward a lower side.

3 . The terminal wireless charging cradle of claim 2 ,

wherein the protrusion is located at a rear end of the first groove when the supporter is at the first position, and

wherein the protrusion is located at a lower end of the second groove when the supporter is at the second position.

4 . The terminal wireless charging cradle of claim 1 , wherein the recess comprises:

a first surface recessed with a first depth with respect to an upper surface of the body, the supporter at the first position being seated thereon; and

a second surface recessed with a second depth deeper than the first depth with respect to the upper surface of the body, located in front of the first surface, and supporting a lower end of the supporter at the second position.

5 . The terminal wireless charging cradle of claim 4 , wherein the recess further comprises a third surface connecting the first surface and the second surface and located at a lower rear side of the supporter at the second position.

6 . The terminal wireless charging cradle of claim 5 , wherein the third surface comprises:

a flat portion formed in parallel with a rear surface of the supporter at the second position and connected to the second surface; and

a curved portion connecting the flat portion and the first surface in a round manner.

7 . The terminal wireless charging cradle of claim 6 , wherein the guide groove comprises:

a first groove extending horizontally; and

a second groove extending to be inclined downward in a direction parallel to the flat portion from a front end of the first groove.

8 . The terminal wireless charging cradle of claim 1 , wherein a front surface of the supporter at the second position is spaced apart rearward from an inner front surface of the recess.

9 . The terminal wireless charging cradle of claim 1 ,

wherein a first hole, through which a cable connected to the wireless charging circuit passes, is formed in at least one of the pair of protrusions, and

wherein a second hole communicating with an internal space of the body and having a shape corresponding to the guide groove and having the cable passing therethrough is formed in at least one of the pair of guide grooves.

10 . The terminal wireless charging cradle of claim 1 , wherein a front surface of the supporter is inclined in an inclined direction toward the rear toward an upper side when the supporter is at the second position.

11 . A display device comprising:

a base;

a stand vertically extending upward from the base;

a head provided with a display and connected to the stand; and

a cradle located at a lower height than the head and connected to the stand,

wherein the cradle comprises:

a body disposed horizontally;

a recess formed to be stepped downward from an upper surface of the body;

a supporter having a wireless charging circuit built therein and movable between a first position laid down in the recess and a second position erected to protrude upward from the recess;

a pair of guide grooves formed in both inner surfaces of the recess; and

a plurality of protrusions protruding from both lower sides of the supporter into the pair of guide grooves and sliding along the pair of guide grooves when the supporter moves.

12 . The display device of claim 11 , further comprising a processor configured to mirror a screen displayed on a display of a terminal supported on the supporter to a display of the head.

13 . The display device of claim 11 , wherein an upper surface of the body comprises:

a first region in which the recess is formed; and

a second region formed to be stepped lower than the first region and located opposite to the stand with the first region interposed therebetween.

14 . The display device of claim 11 ,

wherein a first hole is formed in at least one of the pair of protrusions,

wherein a second hole communicating an internal space of the body and having a shape corresponding to the guide groove is formed in at least one of the pair of guide grooves,

wherein a third hole communicating with the inside of the body is formed in a circumferential surface of the body,

wherein a fourth hole facing the third hole and communicating with the inside of the stand is formed in the stand, and

wherein a cable connected to the wireless charging circuit sequentially passes through the first hole, the second hole, the third hole and the fourth hole and extends into the stand.

15 . The display device of claim 11 ,

wherein a periphery of the head is connected to one side of the stand, and

wherein the cradle is connected to the other side of the stand.
