[0057] FIG. 2 is a drawing showing a portable electronic device according to embodiments. FIG. 3 is a side view of a portable electronic device according to embodiments. FIG. 4 is a drawing showing a portable electronic device according to embodiments. FIG. 5 is a drawing showing the rear side of a portable electronic device according to embodiments.

[0058] The portable electronic device (200) illustrated in FIG. 2 may correspond to the portable electronic device (100) illustrated in FIG. 1. The portable electronic device (200) illustrated in FIG. 3 may correspond to the portable electronic device (100) illustrated in FIG. 1 and the portable electronic device (200) illustrated in FIG. 2. The portable electronic device (200) illustrated in FIG. 4 may correspond to the portable electronic device (100) illustrated in FIG. 1 and the portable electronic devices (200) illustrated in FIG. 2 and FIG. 3. The portable electronic device (200) illustrated in FIG. 5 may correspond to the portable electronic device (100) illustrated in FIG. 1 and the portable electronic devices (200) illustrated in FIG. 2 to FIG. 5.

[0059] Referring to FIGS. 2 and 3, a portable electronic device (200) according to embodiments may include a first body (210), a second body (220), and a link member (230).

[0060] Referring to FIG. 2, the first body (210) may have a display portion formed on the front side (x-axis direction). Similarly, the second body (220) may have a keypad portion formed on the front side (x-axis direction).

[0061] The first body (210) and the second body (220) can be connected by a link member (230). More specifically, as illustrated in FIG. 3, the link member (230) can connect the first body (210) and the second body (220) by having one side hinge-connected to a specific point on the rear surface of the first body (210) and the other side hinge-connected to the upper surface of the second body (220). A detailed description of the link member (230) will be described with reference to FIG. 6.

[0062] One side of the link member (230) is hinge-connected to the rear side of the first body (210), and the other side is hinge-connected to the upper side of the second body (220), so that the first body (210) can rotate with respect to one side of the link member (230) by the rotation of the link member (230). The first body (210) may be in a first state in which the rear side faces the front side of the second body (220), as illustrated in FIG. 2, or may be in a second state in which the lower side forms a predetermined angle with the upper side of the second body (220), as illustrated in FIG. 4.

[0063] That is, FIG. 2 is a drawing showing a portable electronic device (200) in which a first body (210) is in a first state, and FIG. 4 is a drawing showing a portable electronic device (200) in which a first body (210) is in a second state. The state transition of the first body (210) of the portable electronic device (200) according to embodiments will be described in detail in FIG. 7.

[0064] Referring to FIG. 4, the second body (220) may be formed with a track pad (trackpad, 221), a dial pad (dialpad, 222), and a track pad (223) having a ring-shaped concave groove formed on the front (x-axis direction).

[0065] More specifically, the dial pad (222) can be attached to the track pad (221). For example, magnets may be attached to the edge of the track pad (221) and the edge of the dial pad (222). In this case, the recessed portion of the track pad (221) formed and the pad portion of the dial pad (222) may have the same thickness. That is, the pad of the dial pad (222) may be attached to the track pad (221) by a force exerted by the magnet attached to the edge and the magnet attached to the edge of the track pad (221). At this time, the dial of the dial pad (222) may have a spherical pad at the bottom, and thus the rotation of the dial may be recognized by the track pad (221).

[0066] Accordingly, the portable electronic device (200) according to the embodiments has the effect that the user can selectively use the desired pad among the track pad (221) and the dial pad (222).

[0067] Referring to FIG. 5, the second body (220) may have a handle portion (240) formed at the upper end that can be held by a user. A detailed description of the handle portion (240) will be described in FIG. 6.

[0068] Figure 6 is an exploded view of a portable electronic device according to embodiments.

[0069] The first body (210) illustrated in FIG. 6 may correspond to the first body (210) illustrated in FIGS. 2 to 4. The second body (220) illustrated in FIG. 6 may correspond to the second body (220) illustrated in FIGS. 2 to 5. The link member (230) illustrated in FIG. 6 may correspond to the link member (230) illustrated in FIG. 4.

[0070] Referring to FIG. 6, the link member (230) may include a first hinge portion (231), a second hinge portion (232), a connection portion (233), and a plate portion (235). The plate portion (235) may have a through groove (236) formed in the upper portion thereof in the thickness direction. In this case, the through groove (236) may correspond to the handle portion (240) described in FIG. 5.

[0071] The first hinge portion (231) can hinge-connect one side of the plate portion (235) to the rear surface of the first body (210). In other words, the first body (210) can rotate around the axis of the first hinge portion (231). More specifically, the first body (210) can rotate around one side of the link member (230). Although the first hinge portion (231) illustrated in FIG. 6 is formed as a pair, this is merely an example, and the first hinge portion (231) may also be formed as a single axis.

[0072] The connecting portions (233, 234) can connect the first body (210) and the first hinge portion (231). The connecting portions (233, 234) can include a first connecting portion (233) and a second connecting portion (234). The first connecting portion (233) can have a cylindrical shape that surrounds the first hinge portion (231). The second connecting portion (234) can be a plate-shaped bracket, one side of which can be coupled to the first connecting portion (233) and the other side of which can be coupled to the rear surface of the first body (210).

[0073] That is, when the connecting portion (233, 234) applies force to the front surface of the first body (210), not only can the first body (210) rotate around the axis of the first hinge portion (231) due to the applied force, but one side of the link member (230) can also rotate around the axis of the first hinge portion (231). The rotation will be described in Fig. 7.

[0074] The second hinge portion (232) can hinge-connect the other side of the plate portion (235) to the upper side (220b) of the second body (220). In other words, the other side of the plate portion (235) can rotate around the axis of the second hinge portion (232). More specifically, the other side of the link member (230) can rotate around the upper side (220b) of the second body (220) to which the second hinge portion (232) is coupled. Although the second hinge portion (233) illustrated in FIG. 6 is formed as a pair, this is merely an example, and the second hinge portion (232) may also be formed as a single axis.

[0075] The first hinge portion (231) and the second hinge portion (232) may be formed as a torque hinge capable of withstanding a torque applied by a force so that the first body (210) can be fixed in the first state or the second state. A detailed description of the torque hinge will be described with reference to FIGS. 8 and 9.

[0076] FIG. 7 is a diagram showing changes in the state of a portable electronic device according to embodiments.

[0077] The portable electronic device (200-1) illustrated in FIG. 7 may correspond to the portable electronic device (100) illustrated in FIG. 1 and the portable electronic device (200) illustrated in FIG. 2. The portable electronic device (200-5) illustrated in FIG. 7 may correspond to the portable electronic device (100) illustrated in FIG. 1 and the portable electronic device (200) illustrated in FIG. 4.

[0078] Referring to FIG. 7, a portable electronic device (200) according to embodiments can switch modes from a portable electronic device (200-1) in which a first body (210) is in a first state to a portable electronic device (200-5) in which a first body (210) is in a second state, or conversely, can switch modes from a portable electronic device (200-5) in which a first body (210) is in a second state to a portable electronic device (200-1) in which a first body (210) is in a first state.

[0079] Referring to FIG. 2 together, a portable electronic device (200-1) having a first body (210) in a first state can be fixed to the ground in a stand-type manner and thus can be used in TV mode. In addition, referring to FIG. 4 together, a portable electronic device (200-5) having a first body (210) in a second state can be used in laptop mode because the first body (210) forms a predetermined angle with the second body (220).

[0080] First, let's explain the mode transition in the A direction.

[0081] A user can use the portable electronic device (200-1) in TV mode as described above. The portable electronic device (200-1) in TV mode is a mode in which the first body (210) is in the first state, and the rear surface of the first body (210) and the front surface of the second body (220) are facing each other, so that the user can use the display formed on the front surface of the first body (210).

[0082] At this time, the user can change the mode of the portable electronic device (200-1) in TV mode to the portable electronic device (200-5) in notebook mode by applying force to the first body (210). The user can lay the portable electronic device (200-1) in TV mode on the ground (see portable electronic device (200-2)), and at the same time, push the lower part of the first body (210) (force in the z-axis direction, see FIG. 4) or lift the upper part (force in the x-axis direction, see FIG. 4), thereby changing the state of the first body (210) from the first state to the second state.

[0083] The first body (210) can rotate around one side of the link member (230) by the applied force. More specifically, the first body (210) can rotate counterclockwise around one side (y-axis direction, see FIG. 4) of the link member (230).

[0084] At this time, as described in FIG. 6, not only can the first body (210) rotate around one side of the link member (230) by the connecting portion (233, 234), but also one side of the link member (230) can rotate around a specific point of the first body (210). In other words, the first body (210) and the link member (230) can rotate around the axis of the first hinge portion (231), so that the coupling position of the first body (210) and the link member (230) can change when the mode of the portable electronic device (200) is changed.

[0085] In addition, as the first body (210) rotates, the link member (230) can rotate around the upper part of the second body (220). More specifically, the link member (230) can rotate clockwise around the upper part (y-axis direction, see FIG. 4) of the second body (220).

[0086] Accordingly, when the portable electronic device (200) according to the embodiments is switched from a portable electronic device (200-1) in TV mode to a portable electronic device (200-5) in notebook mode, the first body (210) rotates counterclockwise around one side of the link member (230) and the link member (230) rotates clockwise around the upper part of the second body (220), so that the first body (210) can switch from a first state to a second state. That is, by the applied force, the first body (210) can switch from a first state in which the rear face faces the front of the second body (220) to a second state in which the lower part meets the upper part of the second body (220) and simultaneously forms a predetermined angle.

[0087] Next, let's explain the mode transition in the B direction.

[0088] The user can use the portable electronic device (200-5) in the notebook mode as described above. The portable electronic device (200-5) in the notebook mode is a mode in which the first body (210) is in a second state, and the second state may be a state in which the lower end of the first body (210) meets the upper end of the second body (220) and forms a predetermined angle at the same time. When the first body (210) is in the second state, the front of the second body (220) may be exposed to the user, unlike when the first body (210) is in the first state. Therefore, the user can use the keypad formed on the front of the second body (220).

[0089] At this time, the user can change the mode of the portable electronic device (200-5) in notebook mode to the portable electronic device (200-1) in TV mode by applying force to the first body (210). The user can change the state of the first body (210) from the second state to the first state by pushing the upper part of the first body (210) downward (force in the -x-axis direction, see FIG. 4) or pushing the lower part (force in the -z-axis direction, see FIG. 4). At this time, after the state change of the first body (210) is completed, the user can use the portable electronic device (200-2) lying on the ground by standing it up on the ground (see portable electronic device (200-1)).

[0090] As described above, the first body (210) can rotate around one side of the link member (230) by the applied force. More specifically, the first body (210) can rotate clockwise around one side (y-axis direction, see FIG. 4) of the link member (230). In addition, while the first body (210) rotates, the link member (230) can rotate around the upper part of the second body (220). More specifically, the link member (230) can rotate counterclockwise around the upper part (y-axis direction, see FIG. 4) of the second body (220).

[0091] Accordingly, when the portable electronic device (200) according to the embodiments is switched from a portable electronic device (200-5) in notebook mode to a portable electronic device (200-1) in TV mode, the first body (210) rotates clockwise around one side of the link member (230) and the link member (230) rotates counterclockwise around the upper part of the second body (220), so that the first body (210) can switch from the second state to the first state. That is, by the applied force, the first body (210) can switch from the second state in which the lower part meets the upper part of the second body (220) and at the same time forms a predetermined angle to the first state in which the rear part faces the front of the second body (220).

[0092] As illustrated in FIG. 7, the first body (210) of the portable electronic device (200) according to the embodiments can rotate around a specific point and move in the forward / backward direction (+ / -z-axis direction, see FIG. 4) when switching from a first state to a second state or from a second state to a first state.

[0093] For example, when the mode is switched from a portable electronic device (200-1) in TV mode to a portable electronic device (200-5) in notebook mode, the lower end of the first body (210) can move from a position where it meets the lower end of the second body (220) to a position where it meets the upper end of the second body (220). Accordingly, in this case, the front of the second body (220) can be exposed to the user by being positioned at a position where the lower end of the first body (210) meets the upper end of the second body (220).

[0094] In addition, conversely, when the mode is switched from a portable electronic device (200-5) in notebook mode to a portable electronic device (200-1) in TV mode, the lower end of the first body (210) can move from a position where it meets the upper end of the second body (220) to a position where it meets the lower end of the second body (220). Accordingly, in this case, the front of the second body (220) may not be exposed to the user by being positioned at a position where the lower end of the first body (210) meets the lower end of the second body (220).

[0095] Fig. 8 is a side view of a first state of a portable electronic device according to embodiments. Fig. 9 is a side view of a second state of a portable electronic device according to embodiments.

[0096] The portable electronic device (200) illustrated in FIGS. 8 and 9 may correspond to the portable electronic device (100) illustrated in FIG. 1 and the portable electronic device (200) illustrated in FIGS. 2 to 5 and FIG. 7.

[0097] As described above, the portable electronic device (200) illustrated in FIG. 8 may correspond to a portable electronic device (200-1, see FIG. 7) in TV mode in which the first body (210) is in the first state. In addition, the portable electronic device (200) illustrated in FIG. 9 may correspond to a portable electronic device (200-5, see FIG. 7) in notebook mode in which the first body (210) is in the second state.

[0098] Referring to Fig. 8, the portable electronic device (200) can be placed on the ground. At this time, the lower portion of the first body (210) and the lower portion of the second body (220) can be formed into a curved shape that is bent at a predetermined angle in opposite directions. That is, since the lower portion of the first body (210) and the lower portion of the second body (220) are formed into a curved shape, the user can place the portable electronic device (200) on the ground and use it like a TV.

[0099] Referring to FIG. 9, the portable electronic device (200) can be used with the second body (220) placed on the ground. That is, the user can use the portable electronic device (200) like a laptop.

[0100] At this time, as described above, the lower part of the second body (220) may be formed in a curved shape, so that the second body (220) may have an incline corresponding to the angle of the curved shape with respect to the ground. Accordingly, when a user uses the keypad formed on the front of the second body (220), the second body (220) may have a certain incline, so that the user may feel comfortable when using it. At this time, the degree of bending of the curved shape may correspond to approximately 2.3 degrees.

[0101] In addition, as described above, the lower portion of the first body (210) is formed in a curved shape that bends outward, so that the first body (210) can transition from a first state to a second state (for example, from the first body (210) illustrated in FIG. 8 to the first body (210) illustrated in FIG. 9), or vice versa, can smoothly slide on the front surface of the second body (220). In other words, since the lower portion of the first body (210) is formed in a curved shape, when the first body (210) moves to transition between states, scratches or the like may not occur on the front surface of the second body (220).

[0102] The second state is a state in which the lower end of the first body (210) meets the upper end of the second body (220) and forms a predetermined angle at the same time. At this time, the predetermined angle may correspond to 70 to 80 degrees.

[0103] Accordingly, the portable electronic device (200) according to the embodiments may correspond to the portable electronic device (200) in TV mode as shown in Fig. 8 or the portable electronic device (200) in notebook mode as shown in Fig. 9. In this case, the portable electronic device (200) can maintain the corresponding mode by having the first hinge portion (231) and the second hinge portion (232) support the torque force generated in each mode.

[0104] That is, referring to FIG. 8, in the case of a portable electronic device (200) in TV mode, the first hinge part (231) and the second hinge part (232) support the torque force generated by gravity at the bottom and top, respectively, so that the portable electronic device (200) can maintain the stand type of the TV mode. In addition, referring to FIG. 9, in the case of a portable electronic device (200) in notebook mode, the first hinge part (231) and the second hinge part (232) support the torque force generated by gravity at the top and bottom, respectively, so that the portable electronic device (200) can maintain the notebook mode.

[0105] At this time, the torque force that the first hinge part (231) can withstand may correspond to the torque force applied to the first hinge part (231) in the portable electronic device (200-1, see FIG. 7) in TV mode. The first hinge part (231) must be able to withstand both the torque force applied to the portable electronic device (200-1, see FIG. 7) in TV mode and the portable electronic device (200-5) in laptop mode. At this time, since the torque force applied to the portable electronic device (200-1) in TV mode is greater than the torque force applied to the portable electronic device (200-5) in laptop mode, it may be desirable to set the torque force that the first hinge part (231) can withstand based on the portable electronic device (200-1) in TV mode.

[0106] In addition, the torque force that the second hinge part (232) can withstand may correspond to the torque force applied to the second hinge part (232) in the portable electronic device (200-5, see FIG. 7) in the notebook mode. Similarly, the second hinge part (232) must be able to withstand both the torque force applied to the portable electronic device (200-1, see FIG. 7) in the TV mode and the torque force applied to the portable electronic device (200-5) in the notebook mode. At this time, since the torque force applied to the portable electronic device (200-5) in the notebook mode is greater than the torque force applied to the portable electronic device (200-1) in the TV mode, it may be desirable to set the torque force that the second hinge part (232) can withstand based on the portable electronic device (200-5) in the notebook mode.
