Hereinafter, an electronic pen detachable device according to an example embodiment of the present disclosure will be described in detail with reference to the drawings.

FIGS. 3A and 3B illustrate side views of the electronic pen detachable device 180 of FIG. 1.

The electronic pen detachable device 180 according to the present example embodiment includes a moving body 10, case 20, detector 30, and moving switch 40.

FIG. 3A illustrate a side view of an electronic pen detachable device 180 including the moving body 10.

As the electronic pen 200 is pushed into the mobile device 100, the moving body 10 is attached to the electronic pen detachable device 180 or is separated from the electronic pen detachable device 180. In an embodiment, when the electronic pen 200 is pushed one time into the mobile device 100, the moving body 10 fixes and attaches the electronic pen 200 to the mobile device 100. Further, when the electronic pen 200 is pushed one more time into the mobile device 100, the moving body 10 enables the electronic pen 200 to be exposed from the mobile device 100 to the outside and separates the electronic pen 200 from the mobile device 100.

Referring to FIG. 3A, the moving body 10 includes a body portion 11, hook 12, and push-push structure 13.

The body portion 11 houses the electronic pen 200. As the electronic pen 200 is inserted into the mobile device 100, the body portion 11 houses one end of the electronic pen 200. As the electronic pen 200 is pushed, the body portion 11 may move in a push direction by the push-push structure 13.

In an embodiment, when the electronic pen 200 is pushed one time into the mobile device 100 and is attached to the mobile device 100, until a spring member 13c is pressed to the maximum, the body portion 11 moves in a push direction. Further, when the electronic pen 200 is pushed one more time and is separated from the mobile device 100, the body portion 11 is moved to an original position by an elastic force of the spring member 13c.

When the electronic pen 200 is pushed into the mobile device 100 and is attached to the mobile device 100, the hook 12 performs a function of securely fixing the electronic pen 200. For this, the hook 12 includes a protruded portion 12a housed in at least one groove formed in the electronic pen 200. When the electronic pen 200 is inserted into the mobile device 100 but is not pushed, the protruded portion 12a is not coupled to a groove of the electronic pen 200. However, when the electronic pen 200 is pushed into the mobile device 100, the protruded portion 12a is housed in at least one groove formed in the electronic pen 200. When the electronic pen 200 is completely pushed, the protruded portion 12a close contacts with a groove of the mobile device 100 and is fixed to the groove of the mobile device 100 by a fixing protrusion 40 provided on the rear case 102. In the present example embodiment, the fixing protrusion 40 is provided on the rear case 102, but a position of the fixing protrusion 40 is not limited thereto.

The push-push structure 13 controls the electronic pen 200 to be attached to the electronic pen detachable device 180 or to be separated from the electronic pen detachable device 180. For this, the push-push structure 13 includes a latch pin 13a, a guide rail 13b, and the spring member 13c.

One end of the latch pin 13a is fixed to the case 20. In this embodiment, the latch pin 13a is fixed to rotate using one end thereof as a shaft.

At the other end of the latch pin 13a, a latch protrusion is formed. The latch protrusion is housed in the guide rail 13b to move along the guide rail 13b.

The guide rail 13b forms a path in which the latch protrusion of the latch pin 13a moves. In an embodiment, referring to FIGS. 4A-4D, the guide rail 13b includes a first guide rail 13b-including a first curved portion, a second guide rail 13b-2 including a latch bump, and a third guide rail 13b-3 including a second curved portion.

Referring to FIGS. 4A-4D, the first curved portion performs a function of guiding the latch protrusion to move to the second guide rail 13b-2, and the second curved portion performs a function of guiding the latch protrusion to move to the third guide rail 13b-3. The first curved portion and the second curved portion are obliquely formed in directions of the second and third guide rails 13b-2 and 13b-3, respectively, and may prevent the latch protrusion from moving to the first guide rail 13b-1.

When the electronic pen 200 is pushed from the outside to the inside of the mobile device 100, the same force is applied to the body portion 11 and the guide rail 13b, and while the latch protrusion moves along the guide rail 13b by a force applied to the guide rail 13b, a push-push operation is performed.

FIGS. 4A to 4D illustrate a push operation of the electronic pen detachable device of FIG. 1. In an embodiment, referring to FIG. 4A, before the electronic pen 200 is pushed, the body portion 11 is positioned at a location that can partially expose the electronic pen 200 at the outside by an elastic force (applied in an upper end direction) of the spring member 13c.

Thereafter, when the electronic pen 200 is inserted into the body portion 11 and is pushed to the inside, the body portion 11 moves in a push direction (e.g., lower end direction), the guide rail 13b coupled to the body portion 11 moves to a lower end portion. Accordingly, the latch protrusion moves along the first guide rail 13b-1 and is positioned in the first curved portion, as shown in FIG. 4B.

Thereafter, when a push pressure applied to the electronic pen 100 is terminated, the body portion 11 and the guide rail 13b receive an elastic force applied to an upper end portion by the spring member 13c and moves to the upper end portion. When the guide rail 13b moves to the upper end portion, the latch protrusion moves to the second guide rail 13b-2 along the first curved portion. The latch protrusion receives an elastic force applied to the upper end portion by the spring member 13c and is fixed to a latch bump, as shown in FIG. 4C. In this embodiment, in a groove of the electronic pen 200 inserted into the body portion 11, the protruded portion 12a of the hook 12 is housed and the protruded portion 12a is fixed by the fixing protrusion 40 and thus the electronic pen 200 maintains an attachment state.

When the electronic pen 200 in an attachment state is pushed one more time to the inside, the body portion 11 and the guide rail 13b move in a push direction (lower end direction). Accordingly, the latch protrusion moves from the second guide rail 13b-2 to the third guide rail 13b-3, as shown in FIG. 4D.

The latch protrusion, having moved to the third guide rail 13b-3 is returned to an original state shown in FIG. 4A via the second curved portion. Accordingly, the electronic pen 200 is separated from the hook 12, and while a portion of the electronic pen 200 is exposed to the outside of the electron apparatus 100, the electronic pen 200 can be easily separated.

In the present example embodiment, when the electronic pen 200 is not pushed and is separated by an external force (e.g., when a user extracts the electronic pen 100 by a force), the body portion 11 does not move and thus the push-push structure 13 maintains the same state as a pushed state.

While the latch protrusion moves the guide rail 13b, the spring member 13c moves the body portion 11 by an elastic force. While the latch protrusion moves along the guide rail 13b, the body portion 11 coupled to the guide rail 13b moves together along a moving path formed in the guide rail 13b and performs a push-push operation.

The case 20 may be fixed on the rear case 102. Constituent elements constituting an electronic pen detachable device may be disposed and fixed on the case 20.

The detector 30 detects attachment or separation of the electronic pen 200. The detector 30 includes a switch 31 turned on/off by an external force. In this embodiment, when the switch 31 is turned on, the detector 30 detects that the electronic pen 200 is attached to the mobile device 100, and when the switch 31 is turned off, the detector 30 detects that the electronic pen 200 is separated from the mobile device 100. The detector 30 may be electrically connected to a main board of the mobile device 100, and the main board may control the mobile device 100 according to an on/off signal occurring in the detector 30.

The switch 31 of the detector 30 is positioned to contact with the moving switch 40 or to be separated from the moving switch 40, and as the switch 31 of the detector 30 contacts with the moving switch 40 or is separated from the moving switch 40, on/off of the switch 31 is controlled.

FIG. 3B is a side view illustrating the electronic pen detachable device 180, except for the moving body 10.

Referring to FIG. 3B, the moving switch 40 is formed integrally with the moving body 10. Further, the moving switch 40 controls on/off of the detector 30 by attachment or separation of the electronic pen 200.

For this, the moving switch 40 includes a body portion 41, switch bar 42, and spring member 43.

The body portion 41 houses the electronic pen 200. As the electronic pen 200 is inserted into the mobile device 100, the body portion 41 houses one end of the electronic pen 200. Further, as the electronic pen 200 is attached to the mobile device 100 or is separated from the mobile device 100, the body portion 41 may move in an attaching and detachable direction (e.g., vertical direction). As the body portion 41 of the moving switch 40 is inserted into the body portion 11 of the moving body 10, the body portion 41 of the moving switch 40 may be integrally formed with the body portion 11 of the moving body 10.

The switch bar 42 is extended toward the detector 30 from the body portion 41. One end of the switch bar 42 contacts with the switch 31 of the detector 30 or is separated from the switch 31 of the detector 30 by attachment or separation of the electronic pen 200. By contact or separation of the switch bar 42, the detector 30 detects attachment and separation of the electronic pen 200. The switch bar 42 is formed to turn on/off a switch, and a shape or a length of the switch bar 42 is not particularly limited.

The spring member 43 is coupled to the switch bar 42, and is disposed to elastically contact with the body portion 41. When the electronic pen 200 is attached to the mobile device 100, the spring member 43 is retracted and thus the switch bar 42 contacts with the detector 30, and when the electronic pen 200 is separated from the mobile device 100, the switch bar 42 is separated from the detector 30 by an elastic force.

In an embodiment, when the electronic pen 200 is attached to the mobile device 100, the body portion 41 moves in an attaching direction (e.g., lower end direction) by an external force. As the body portion 41 moves, the switch bar 42 connected to the body portion 41 moves to contact with the switch 31 of the detector 30. The switch 31 is controlled to an on state by contact with the switch bar 42. In this embodiment, an attaching direction may be the same as a push direction.

In contrast, when the electronic pen 200 is separated from the mobile device 100, the body portion 41 moves in an operating direction, for example an upper end direction of an elastic force by an elastic force of the spring member 43. The switch bar 42 connected to the body portion 41 moves together to an upper end portion according to movement of the body portion 41 and is separated from the switch 31 of the detector 30. The switch 31 is controlled to an off state by separation of the switch bar 42.

The body portion 41 of the moving switch 40 can receive an elastic force by the spring member 43 in an upper end direction regardless of a push-push operation of the moving body 10. Therefore, even if the electronic pen 200 is not pushed but is separated by an external force, the moving switch 40 performs operation by separation of the electronic pen 200. That is, the body portion 41 of the moving switch 40 and the switch bar 42 coupled to the body portion 41 move by an elastic force of the spring member 43 and are separated from the switch 31 to control the switch 31 to an off state.

FIG. 5 illustrates an exploded view of constituent elements of the electronic pen detachable device 180 of FIG. 1, however constituent elements of the electronic pen detachable device 180 are not limited to a shape and a size shown in FIG. 5 and may be variously changed within the spirit and scope of the present disclosure.

Although the present disclosure has been described with an example embodiment, various changes and modifications may be suggested to one skilled in the art. It is intended that the present disclosure encompass such changes and modifications as fall within the scope of the appended claims.
