Description

Electronic device including a door and a door control method

[0001] The present disclosure relates to an electronic device including a door and a method for controlling the door.

[0002] Various types of electronic devices, such as refrigerators, microwave ovens, and washing machines, include at least one door. In the past, manual opening and closing methods were mostly applied, where the user had to manually grab and open the door; however, recently, automatic opening and closing methods that allow the door to be opened and closed with just a simple button operation are also being applied.

[0003] When implemented with an automatic opening and closing mechanism, users can open or close the door without exerting much force, thereby increasing user convenience. However, when using an electronic device with an automatic opening and closing mechanism, users who overlook this may inadvertently apply force to manually open or close the door. In this case, there is a possibility that the parts used to open the door may be damaged.

[0004] In addition, in the case of automatic opening and closing systems, there is also a problem in that the door cannot be operated at all if a power outage occurs or the electronic device's battery runs out.

[0005] Accordingly, the need arose to develop a structure capable of both automatic and manual opening and closing.

[0006] An electronic device according to at least one embodiment of the present disclosure comprises a main body, a door connected to the main body, and a driving device for opening and closing the door. It includes an actuator movable by the driving device and a link member that opens or closes the door in conjunction with the movement of the actuator. The driving device moves the actuator in a first direction to open the door, and when the door is opened, moves the actuator to a position where the door can be manually closed, and moves the actuator in a second direction opposite to the first direction to close the door, and when the door is closed, moves the actuator to a position where the door can be manually opened.

[0007] According to at least one embodiment of the present disclosure, a door control method of an electronic device comprising a door, a link member connected to the door, and an actuator for moving the link member comprises: a door opening step of moving the actuator in a first direction to open the door and, when the door is opened, moving the actuator to a position where the door can be manually closed; and a door closing step of moving the actuator in a second direction opposite to the first direction to close the door and, when the door is closed, moving the actuator to a position where the door can be manually opened.

[0038] An embodiment of the present disclosure will be described in more detail below with reference to the attached drawings.

[0039] FIG. 1 is a drawing showing the external appearance of an electronic device according to at least one embodiment of the present disclosure. Various embodiments of the present disclosure may be implemented as various types of electronic devices having a door. For example, the electronic device may be implemented as various types such as a microwave oven, smart cooker, air fryer, oven, refrigerator, washing machine, dishwasher, etc. However, it is not necessary to implement it as an electronic device, and it may also be applied to various types of devices such as furniture or sinks that include a door. The following description is based on the case where it is applied to a microwave oven.

[0040] According to FIG. 1, the electronic device (100) includes a main body (1) and a door (110).

[0041] The main body (1) is a part for performing the specific operation of the electronic device (100). For example, if implemented as a microwave oven, the main body (1) includes an internal space such as a cooking chamber equipped with a turntable. The door (110) is configured to cover the entrance, i.e., the opening, of the internal space.

[0042] The door (110) can be implemented in various sizes, shapes, and materials depending on the type of electronic device (100). For example, if the electronic device (100) is implemented as a microwave oven, the door (110) may be in a form that includes a transparent area that allows the interior to be seen. The opening and closing structure of the door (110) can be implemented in various ways depending on the opening direction. For example, it can be implemented in various forms such as a lift-up structure that opens by lifting the door while keeping it away from the opening without rotating it, a swing structure that opens by rotating the door clockwise or counterclockwise around the hinge connecting the left or right side of the door to the main body, a down-up structure that opens by rotating the door downward around the hinge connecting the lower side of the door to the main body, an up-down structure that opens by rotating the door upward around the hinge connecting the upper side of the door to the main body, and a slide structure that opens by sliding the door upward, left, right, etc.

[0043] Figure 1 illustrates a case implemented as an up-down structure that opens by rotating upwards.

[0044] FIG. 2 is a block diagram showing the configuration of an electronic device according to at least one embodiment of the present disclosure. According to FIG. 2, the electronic device (100) includes a UI panel (120), a controller (130), and a door opening / closing device (200).

[0045] A door opening / closing device (200) is a configuration for opening or closing a door (110). The door opening / closing device (200) includes a driving device (210), an actuator (220), and a link member (230). The door opening / closing device (200) may be formed integrally with the door (110) and mounted on the electronic device (100), or it may be mounted on the electronic device (100) separately from the door (110). When formed integrally with the door (110), the door opening / closing device (200) may receive power from an independent power source (e.g., a battery) separate from the electronic device (100) to perform door opening / closing operations.

[0046] The driving device (210) is configured to automatically open or close the door (110). The driving device (210) includes at least one motor, at least one gear, at least one shaft, etc., and can transmit force to open or close the door using these components. Specifically, the driving device (210) can rotate at least one motor clockwise or counterclockwise according to the control of the controller (130). At least one gear connected to the motor can move the actuator (220) using the rotational force of the motor.

[0047] The actuator (220) is configured to be movable by the driving device (210). The link member (230) is configured to move the door in conjunction with the movement of the actuator (220). The structure and type of the actuator (220) and the link member (230) may vary depending on the embodiment.

[0048] The UI panel (120) is configured to receive various user commands. The UI panel (120) may be placed in an area of ​​the exterior of the electronic device (100). As shown in FIG. 1, if the entire front of the electronic device (100) is composed of a door (110), the UI panel (120) may be placed on a part of the surface of the door (110), or the UI panel (120) may be placed on the upper panel or side panel of the main body (1). Alternatively, the UI panel (120) may be described using various terms such as operation panel, control panel, UI (User Interface), etc.

[0049] The UI panel (120) may include various buttons, a wheel, a light-emitting element, a display, etc. that can be operated by a user. Alternatively, the UI panel (120) may include a touch screen. When user operation on a button, wheel, touch screen, etc. is input, the UI panel (120) transmits an electrical signal corresponding to the user operation to the controller (130). The controller (130) can perform a control operation corresponding to the received electrical signal.

[0050] For example, when a door opening button or a door closing button provided on a UI panel (120) is selected by the user, the controller (130) can control the driving device (210) to perform a door opening operation or a door closing operation.

[0051] The controller (130) is a component for controlling the operation of the electronic device (100). For example, the controller (130) may be implemented as a control circuit including at least one transistor switch. When an electrical signal corresponding to a door open button is transmitted from the UI panel (120), the controller (130) may transmit a first driving signal to the driving device (210) to rotate the motor of the driving device (210) in a preset first direction. On the other hand, when an electrical signal corresponding to a door close button is transmitted, the controller (130) may transmit a second driving signal to the driving device (210) to rotate the motor of the driving device (210) in a second direction opposite to the first direction. The first and second driving signals may be electrical signals having different polarities (for example, pulse signals).

[0052] The controller (130) is not necessarily implemented in this structure and may be implemented as one or more IC (integrated circuit (or circuitry)) chips including a processor and memory. In this case, the controller (130) may include one or more processing circuits capable of individually or collectively distributing and processing instructions (or programs, data, etc.) stored in memory. Alternatively, the controller (130) may be implemented as a system on chip (SoC) (e.g., a single chip or chipset), multiple cores (or at least one core circuit), multiple chips, or multiple chipsets. For example, the controller may be implemented as a central processing unit (CPU), a graphics processing unit (GPU), a neural processing unit (NPU), an image signal processor (ISP), and various other forms.

[0053] The driving device (210) can automatically perform a door opening operation or a door closing operation according to the control of the controller (130).

[0054] Specifically, when an event occurs that requires the door to be opened, the driving device (210) can move the actuator (220) in a first direction to open the door (110). The event that requires the door to be opened may include various cases, such as when a user presses a door opening command, when a timer is set to perform a door opening operation and the set time arrives, when a task being performed on the main body (1) of the electronic device (100) is completed (e.g., cooking is finished), or when the electronic device (100) is turned on.

[0055] When the actuator (220) moves in the first direction, the link member (230) moves in conjunction with it, thereby opening the door (110). When the door is opened, the driving device (210) moves the actuator (220) to a position where manual closing of the door is possible. A position where manual closing is possible is a position where, when a user manually closes the door (110), there is no interference between the actuator (220) and the various parts connected to the door (110). In this way, by readjusting the position of the actuator after opening the door, the user can close the door not only automatically but also manually. Since this position may vary depending on the structure of the actuator (220) and the link member (230), it will be explained in detail later with the drawings.

[0056] When an event occurs that requires closing the door, the driving device (210) can close the door (110) by moving the actuator (220) in a second direction opposite to the first direction.

[0057] Events requiring the door to be closed may include various cases, such as when a user presses a door closing command, when food or the like is placed inside the main body (1) and a cooking button is pressed, when the door is not closed until a certain amount of time has elapsed after the door is opened, or when a turn-off command is input to the electronic device (100).

[0058] After the door is closed, the driving device (210) moves the actuator to a position where the door can be opened manually. The position where manual opening is possible is a position where there is no interference between the various parts connected to the door (110) and the actuator (220) when the user opens the door (110) manually. In this way, by readjusting the position of the actuator after the door is closed, the user can open the door not only automatically but also manually. Since this position may vary depending on the structure of the actuator (220) and the link member (230), it will be explained in detail later with the drawings.

[0059] FIG. 3 is a drawing showing the internal configuration of an electronic device according to at least one embodiment of the present disclosure. FIG. 3 illustrates the internal structure viewed from the side of the electronic device (100). FIG. 3 illustrates a case where the actuator (220) is implemented as a push-pull rod (300) and the link member (230) is implemented as a triangular link (400).

[0060] Referring to FIG. 3, a door (110) is positioned on the front of the main body (1). As in FIG. 1, when the electronic device (100) is implemented as a rectangular microwave oven with a door that opens and closes in an up-down structure, the main body (1) includes an upper panel, two side panels, a lower panel, and a rear panel based on the internal space. All or part of the front of the main body (1) forms an opening. Through the opening, a user can place food in the space inside the main body (1). The opening is opened and closed by the door (110). The door (110) is rotatably connected (e.g., hinged) to the upper panel of the main body (1), so that the opening can be opened and closed in an up-down manner by driving the drive device (210) or by manual operation.

[0061] The driving device (210) and the push-pull rod (300) may be positioned on the upper panel of the main body (1). By driving the driving device (210), the push-pull rod (300) may move toward the door (210), i.e., in the first direction, or in the opposite direction, in the second direction.

[0062] When the push-pull rod (300) moves in the first direction and pushes the triangular link (400), the triangular link (400) rotates and moves the door (110) to open it.

[0063] Meanwhile, a gas spring (500) may be placed on one or both sides of the door (110). The gas spring (500) is configured to push the door until it is fully opened when the door (110) is partially opened by the push of the push-pull rod (300). By installing the gas spring (500), the door (110) can be fully opened even if the push-pull rod (300) pushes the triangular link (400) only to a certain distance without pushing it all the way to the end. When the door is opened, the drive device (210) moves the push-pull rod (300) a certain distance in a second direction. Accordingly, even if the triangular link (400) rotates while the user presses to manually close the door (110) in a fully open state, it is not interfered with by the push-pull rod (300).

[0064] When the push-pull rod (300) moves in the second direction to pull the triangular link (400), the triangular link (400) rotates in the opposite direction, moving the door (110) to close it. Once the door (110) is closed, the drive device (210) moves the push-pull rod (300) a certain distance in the first direction. Accordingly, even if the triangular link (400) rotates while the user pulls the door (110) to manually open it while the door (110) is in a completely closed state, it is not interfered with by the push-pull rod (300).

[0065] As a result, both automatic and manual opening and closing become possible.

[0066] FIG. 4 is a drawing showing an example of a driving device and an actuator used in an electronic device according to at least one embodiment of the present disclosure.

[0067] According to FIG. 4, the driving device (210) includes a motor (211) and at least one gear (212). The motor (211) may receive a first driving signal or a second driving signal from a controller (130) or other electronic circuits that operate under the control of the controller (130). When the first driving signal is input, the motor (211) rotates in a first direction (e.g., clockwise), and when the second driving signal is input, the motor (211) may rotate in a second direction opposite to the first direction. The rotation in the first direction may be referred to as forward rotation, and the rotation in the second direction may be referred to as reverse rotation. The rotational force of the motor is reduced by a predetermined reduction ratio by at least one gear (212) and transmitted to a push-pull rod (300).

[0068] When the motor (211) rotates in the forward direction, at least one gear (212) can move the push-pull rod (300) in the first direction, that is, toward the door (110). On the other hand, when the motor (211) rotates in the reverse direction, at least one gear (212) can move the push-pull rod (300) in the second direction opposite to the first direction.

[0069] The push-pull rod (300) engages with at least one gear (212) and can move in a first direction or a second direction depending on the rotational direction of the gear. In FIG. 4, the push-pull rod (300) is shown in a form including a push-pull body (310) and a connecting part (320) connected to the push-pull body (310), but it is not necessarily limited thereto, and the push-pull rod (300) may be implemented as a single unit. In the case of implementation as a single unit, at least a part of the push-pull rod (300) may be made of a flexible material that can be bent within a certain angle by the rotation of the triangular link (400).

[0070] The push-pull body (310) is a bar-shaped member having teeth formed thereon that mesh with at least one gear (212) provided in the drive unit (210).

[0071] The connecting part (320) can be connected to the push-pull body (310) in a rotatable manner by means of a hinge (311) provided at one end of the push-pull body (310). Referring to FIG. 4, the connecting part (320) can be rotated upward or downward. The connecting part (320) is configured to contact the triangular link (400) to transmit the movement of the push-pull rod (300) to the triangular link (400). The end portion of the connecting part (320) can be implemented in the form of a roller (321) that can move along the inner surface of the triangular link (400). The roller (321) can move while rotating along the inner surface while in direct contact with the triangular link (400). To prevent friction noise or damage, the roller (321) can be implemented with an elastic material (e.g., rubber, etc.), but is not necessarily limited thereto. Additionally, the roller (321) is not necessarily required, and the end portion of the connecting part (320) may be implemented in a form that directly contacts the inner surface of the triangular link (400).

[0072] FIGS. 5 and 6 are drawings for illustrating an example of a link member used in an electronic device according to at least one embodiment of the present disclosure.

[0073] According to FIGS. 5 and 6, the triangular link (400) can be implemented as a structure in which three sides (411, 421, 431) and a support member (405) are integrally formed. The support member (405) includes at least one fastening groove for coupling to the door (110). The support member (405) can be connected to the door (110) by means of a fastening member such as a bolt.

[0074] An internal space (401) is formed between the three sides (411, 421, 431), and the point where the three sides (411, 421, 431) meet forms a corner (410, 420, 430). For convenience of explanation, the corner on the side of the support member (405) among the three corners is referred to as the first corner (410), the upper corner as the second corner (420), and the opposite corner as the third corner (430). Additionally, the side connecting the first and second corners (410, 420) is referred to as the first side (411), the side connecting the second and third corners (420, 430) is referred to as the second side (421), and the side connecting the third and first corners (430, 410) is referred to as the third side (431).

[0075] As illustrated, the first side (411) is a curved shape that is convexly bent inward toward the triangular link (400), the second side (421) is a curved shape that is convexly bent outward toward the triangular link (400), and the third side (431) is a straight shape. The roller (321) of FIG. 4 can be positioned at one of the first to third corners (410, 420, 430) while moving along the inner surface of each of the first to third sides (411, 421, 431) within the internal space (405) of the triangular link (400). Since the connecting part (320) and the push-pull body (310) are connected in a rotatable manner, movement along the curved first and second sides is possible. A rail may be formed on the inner surface of each of the first to third sides (411, 421, 431) to allow the roller (321) to move easily.

[0076] FIGS. 7 and FIGS. 8 are drawings for explaining the operation of a gas spring used in an electronic device according to at least one embodiment of the present disclosure. FIG. 7 shows a door (110) in a fully open state, and FIG. 8 shows a door in a fully closed state.

[0077] A gas spring (500) is connected to the door (110) and can provide additional force to open or close the door (110).

[0078] Referring to FIG. 7, the gas spring (500) includes a cylinder (510) and a piston rod (520). The cylinder (510) may be filled with a gas of a certain pressure, such as nitrogen gas. The piston rod (520) is connected to a piston (not shown) that is in close contact with the side wall of the cylinder (510) inside the cylinder (510), and can extend outward from the cylinder (510) when the piston is pushed out by the pressure of the gas.

[0079] The end of the cylinder (510) is connected to a first fastening part (11) provided on the main body (1), and the end of the piston rod (520) is connected to a second fastening part (111) provided on one side of the door (110). Accordingly, when the piston rod (520) extends outward from the cylinder (510), the door (110) can be opened while rotating from the main body (1).

[0080] Specifically, when the push-pull rod (300) moves in the first direction and pushes the triangular link (400), it is partially opened by the rotation of the triangular link (400). Accordingly, the piston rod inserted into the cylinder of the gas spring (500) extends from the cylinder by a certain distance or more, and subsequently, it is pushed out and unfolded by the expansion force of the internal gas of the cylinder (510). Since the cylinder (510) is connected to the main body (1) and the piston rod (520) is connected to the door (110), as the piston rod (520) extends, it pushes the door (110) away from the main body (1), thereby achieving full opening. In the present disclosure, partial opening means a state in which the piston rod of the gas spring (500) is opened to an angle (e.g., 15 to 45 degrees) sufficient to receive expansion force, and full opening means a state in which the door is fully opened within the hinge allowable limit. When implemented with a structure like that of Fig. 3, the door (110) when fully opened forms an angle of about 90 degrees with the main body (1).

[0081] When the door (110) is closed, the piston rod (520) enters the cylinder (510) with the piston rod inserted inside, as shown in FIG. 8.

[0082] FIGS. 9 to 11 are drawings sequentially illustrating the process of opening a door in an electronic device according to at least one embodiment of the present disclosure.

[0083] FIG. 9 is a drawing showing a state in which a door is partially opened in an electronic device according to at least one embodiment of the present disclosure. When an event occurs in which the door must be opened, the driving device (210) moves the push-pull rod (300) in a first direction so that the first corner (410) can be pushed while the push-pull rod (300) is in contact with the first corner (410) of the triangular link (400). The triangular link (400) rotates while being pushed by the push-pull rod (300), and the door (110) rotates together with the rotation of the triangular link (400) and is partially opened. FIG. 9 shows a state in which the door is opened by an angle θ. When the door is partially opened by an angle θ, the gas spring (500) operates to fully open the door.

[0084] FIG. 10 is a drawing showing a fully open state of a door in an electronic device according to at least one embodiment of the present disclosure.

[0085] While the door (110) is partially opened by an angle θ, the piston rod (520) protrudes partially from the cylinder (510) in the gas spring (500) connected between the main body (1) and the door (110). When the piston rod (520) protrudes beyond a certain distance, it automatically extends to the remaining portion by the pressure of the internal gas. Thus, even if the push-pull rod (300) does not fully open the door (110), the door can be fully opened by the action of the gas spring (500).

[0086] A partial opening angle θ can be set to an angle such that the cylinder (510) of the gas spring (500) can push the piston rod (520), and the distance the push-pull rod (300) moves in the first direction can be determined based on the partial opening angle.

[0087] Referring to FIG. 10, the driving device (210) can stop the pushing operation after pushing the push-pull rod (300) until the triangular link (400) is partially opened by an opening angle θ. Accordingly, the end portion of the push-pull rod (300) can temporarily stop at the final position where it was pushing the first corner (410) of the triangular link (400). As shown in FIG. 3, if a roller (321) is placed at the end portion of the push-pull rod (300), the position of the roller becomes the end portion of the push-pull rod (300). Subsequently, the door (110) is fully opened by the action of the gas spring (500). The position where the roller (321) stops can be a point on the first side (411) connecting the first corner (410) and the second corner (420) of the triangular link (400). Even if the push-pull rod (300) stops after pushing the first corner (410), while the triangular link (400) rotates by the gas spring (500), the roller (321) in contact with the first corner (410) automatically moves along the first side (411) from the first corner (410) toward the second corner (420).

[0088] The driving device (210) readjusts the position of the push-pull rod (300) after the door is fully opened or while it is fully opened so that no interference occurs during manual closing.

[0089] FIG. 11 is a drawing for explaining the process of adjusting the actuator position after opening a door in an electronic device according to at least one embodiment of the present disclosure.

[0090] According to FIG. 11, the drive device (210) moves the push-pull rod (300) in a second direction after the door is fully opened or while it is fully opened, so that the roller (321) is positioned at the second corner (420) of the triangular link (400). In this state, when the user manually closes the door (110), the triangular link (400) connected to the door (110) rotates so that the second corner (420) moves upward. At this time, since the roller (321) is positioned at the second corner (420), the roller (321) naturally moves toward the third corner (430) along the second side (421) of the triangular link (400). Therefore, even if the user manually closes the door (110) after it has been automatically opened, no damage is caused by interference between the parts.

[0091] When an event occurs where the door (110) needs to be closed while the door (110) is fully open, the drive unit (210) moves the push-pull rod (300) in a second direction while the roller (321) of the push-pull rod (300) is positioned at the second corner (420) of the triangular link (400). Accordingly, the push-pull rod (300) pulls the triangular link (400), and as a result, the triangular link (400) rotates, closing the door (110).

[0092] FIGS. 12 and FIGS. 13 are drawings for explaining a method of closing a door in an electronic device according to at least one embodiment of the present disclosure.

[0093] According to FIG. 12, as the push-pull rod (300) moves in the second direction, the roller (321) moves along the second side (421) from the second corner (420) of the triangular link (400) toward the third corner (430), thereby pulling the triangular link (400). Accordingly, the triangular link (400) rotates clockwise in FIG. 12, closing the door (110).

[0094] FIG. 13 is a three-dimensional drawing illustrating the operation of closing a door in an electronic device. Referring to FIG. 12 and FIG. 13, as the door (110) is closed by the rotation of the triangular link (400), the piston rod (520) of the gas spring (500) also enters the cylinder (510).

[0095] FIG. 14 is a drawing showing a state in which a door is completely closed in an electronic device according to at least one embodiment of the present disclosure. According to FIG. 14, when the door (110) is completely closed, the roller (321) of the piston rod (300) is positioned at the third corner (430) of the triangular link (400). After the door is completely closed, the driving device (210) readjusts the position of the piston rod (300) so that no interference occurs during manual opening.

[0096] FIG. 15 is a diagram illustrating a method for readjusting the position of an actuator, i.e., a piston rod, after the door is completely closed. Specifically, when the door is closed, the driving device (210) moves the piston rod (300) back to the first direction. Accordingly, the position of the roller (321) moves from the third corner (430) of the triangular link (400) to the first corner (410). In this state, when a user pulls the door (110) to open it manually, the triangular link (400) rotates while the roller (321) maintains its position, so the position of the roller (321) naturally changes from the first corner (410) to the second corner (420). That is, even if the user opens the door manually after it has been automatically closed, there is no interference between the parts.

[0097] In the above, the illustration and description are based on the case where an up-down structure door that opens from bottom to top is used. In the above embodiments, the door (110) is connected to the upper panel of the main body (1) so as to be rotatable, and may be opened and closed automatically according to the operation of the driving device (210), or may be opened and closed manually by manual operation by a user.

[0098] However, the structure and opening / closing direction of the door, the position of the driving device (210) and actuator (220), and the connection position and connection structure between the door (110) and the main body (1) are not necessarily limited to these and can be varied according to the embodiment. In addition, the type and shape of the actuator (220) and the link member (230) can also vary.

[0099] FIG. 16 is a drawing showing the internal configuration of an electronic device according to another embodiment of the present disclosure. Specifically, FIG. 16 illustrates a case where an actuator (220) is implemented as a rack gear (1600) and a link member (230) is implemented as a connecting link (1700) in which a plurality of members (1710, 1720, 1730) are connected to each other. The right side of FIG. 16 is an enlarged view of the rack gear (1600) and the connecting link (1700).

[0100] The rack gear (1600) may have teeth formed on its outer side that mesh with at least one gear included in the drive device (210). Accordingly, the rack gear (1600) can move in a first direction (downward direction in the case of FIG. 16) or the opposite second direction (upward direction in the case of FIG. 16) by the drive of the drive device (210). As shown in FIG. 16, if the main body (1) is rectangular in shape and the door (110) covers the opening on the front of the main body (1) and is structured to open and close in an up-down manner from bottom to top, the drive device (210), rack gear (1600), connecting link (1700), etc. may be provided on one side of the main body (1) or commonly arranged on both sides.

[0101] The connecting link (1700) includes a clutch (1710), at least one straight link (1720), and at least one L-type link (1730).

[0102] The clutch (1710) is structured to be movable along the inner circumference of the rack gear (1600) within the inner space (1610) of the rack gear (1600). As shown in FIG. 16, if the rack gear (1600) is structured to be elongated on one side, the inner space of the rack gear (1600) can also be formed elongated along the longitudinal direction of the rack gear (1600). The two ends of the inner space are described as corners in this disclosure. That is, the inner space (1610) of the rack gear (1600) includes a first corner (1611) on one side and a second corner (1612) on the opposite side. The clutch (1710) can move between the first corner (1611) and the second corner (1612) within the space formed in the rack gear (1600).

[0103] As shown in FIG. 16, if the door (110) is closed, the clutch (1710) may be located at the second corner (1612) in the internal space (1610) of the rack gear (1600). Additionally, the straight link (1720) and the L-type link (1730) may be folded so as to be close to each other. In the present disclosure, L-type refers to a shape in which one point of the link is bent. Referring to FIG. 16, the L-type link (1730) may be implemented in a form in which the long side and the short side are connected perpendicularly to each other, with the long side fixed to the door (110) and the short side connected to the straight link (1720).

[0104] The straight link (1720) can be rotatably connected to the clutch (1710) at its first stage, and rotatably connected to the L-type link (1730) at its second stage, opposite to the first stage. Accordingly, a force corresponding to the direction of movement of the clutch (1710) can be transmitted to the L-type link (1730). That is, when a user manually opens the door (110), the straight link (1720) and the L-type link (1730) separate, causing the straight link (1720) to push the clutch (1710) downward.

[0105] FIG. 17 is a diagram illustrating the process of manually opening a door in the electronic device of FIG. 16. As the straight link (1720) pushes the clutch (1710) downward, the clutch (1710) moves along the internal space of the rack gear (1600) from the second corner (1612) position toward the first corner (1611). When the door (110) is fully opened, the clutch (1710) is positioned at the first corner (1611). That is, even when opening manually, there is no significant interference with the movement of the clutch (1710).

[0106] Apart from manual opening, the electronic device (100) may also automatically open the door.

[0107] FIG. 18 is a diagram illustrating a method for automatically opening a door in the electronic device of FIG. 16. When an event occurs that requires opening the door, the drive unit (210) moves the rack gear (1600) in a first direction, that is, downward. In this case, the clutch (1710), which was located at the upper second corner (1612) position within the internal space (1610) of the rack gear (1600), moves downward together with the rack gear (1600) while in contact with the second corner (1612). The straight link (1720) connected to the clutch (1710) is pulled downward according to the movement of the clutch (1710), and accordingly, the L-type link (1730) connected to the straight link (1720) unfolds as shown by the arrow in FIG. 18, thereby opening the door (110). When the door (110) is opened, the drive unit (210) moves the rack gear (1600) upward so that the clutch (1710) can be in the first corner position. Accordingly, even if the door (110) is manually closed while in the open state, there is no significant interference with the movement of the clutch (1710).

[0108] FIG. 19 is a diagram illustrating a method for automatically closing a door in the electronic device of FIG. 16. When an event occurs that requires closing the door, the drive unit (210) moves the rack gear (1600) in a second direction, that is, upward. In this case, the clutch (1710), which was located at the first corner (1611) position on the lower side within the internal space (1610) of the rack gear (1600), is moved upward together with the rack gear (1600) while in contact with the first corner (1612). The straight link (1720) connected to the clutch (1710) is pushed upward according to the movement of the clutch (1710), and accordingly, the L-type link (1730) connected to the straight link (1720) rotates and folds as shown by the arrow in FIG. 19, thereby closing the door (110).

[0109] FIG. 20 is a diagram illustrating the process of adjusting the actuator position after closing the door in an electronic device. When the door (110) is closed, the drive unit (210) moves the rack gear (1600) downward so that the clutch (1710) can be in the upper second corner position. Accordingly, even if the door (110) is opened manually while in a closed state, there is no significant interference with the movement of the clutch (1710).

[0110] FIG. 21 is a drawing showing the appearance of an electronic device according to another embodiment of the present disclosure. While the other embodiments above were illustrated and described based on an electronic device including a door that opens and closes in an up-down manner, FIG. 21 illustrates an electronic device including a door that opens and closes in a swing structure as an example. In order for the door (110) to open and close in a swing structure as in FIG. 21, a driving device (210), an actuator (220), and a link member (230) may be positioned near a hinge connecting the door (110) and the main body (1) on the upper panel or lower panel of the main body (1).

[0111] According to FIG. 21, the actuator (210) includes a push-pull rod (2100) that engages with at least one gear included in the drive device (210) and a connecting part (2110) connected to the end of the push-pull rod (2100) and in contact with a link member.

[0112] In the other embodiments above, the push-pull rod or rack gear is shown and described as including teeth that mesh with the gear of the drive device (210), but as shown in FIG. 21, the end of the push-pull rod (2100) may be connected to the drive device (210) and implemented in a form that is pulled or pushed by a force applied to the end. The connecting part (2110) may be in the form of the roller described above.

[0113] The link member (230) can be implemented as a fan link (2200) including two straight sides and one curved side.

[0114] FIG. 22 illustrates an example of the structure of a sector link. According to FIG. 22, the sector link (2200) includes two straight sides (2231, 2233) and one curved side (2232). The connection points of each side form corners. In the present disclosure, the connection point between the first straight side (2231), which is one of the two straight sides (2231, 2233), and the curved side (2232) is referred to as the first corner (2210), and the connection point between the second straight side (2233), which is the other of the two straight sides, and the curved side (2232) is referred to as the second corner (2220).

[0115] A connecting part (2201) for joining with the door (110) may be formed at the connection point between two straight sides (2231, 2233) of the fan link (2200). The fan link (2200) may be connected to the door (110) so as to be rotatable in the circumferential direction of the curved side with respect to the connection point.

[0116] The connecting portion (2110) of the push-pull rod (2100) can move between the first corner (2210) and the second corner (2220) according to the direction of movement of the push-pull rod (2100).

[0117] FIG. 23 illustrates the state in which the door (110) is opened in the electronic device of FIG. 21. When an event occurs requiring the door to be opened, the driving device (210) moves the push-pull rod (2100) to push the fan link (2200) while the connecting part (2110) is positioned at the first corner (2210) of the fan link (2200). Accordingly, the door (110) can be opened as the fan link (2200) rotates clockwise. When the door (110) is opened, the driving device (210) pulls the push-pull rod (2100) to position the connecting part (2110) at the second corner (2220) of the fan link (2200). Accordingly, even if the user manually closes the opened door, no interference between parts occurs.

[0118] FIG. 24 shows the state in which the door (110) is closed in the electronic device of FIG. 21. When an event occurs that the door must be closed, the driving device (210) can move the push-pull rod to pull the fan link (2200) while the connecting part (2110) is positioned at the second corner (2220) of the fan link (2200). Accordingly, the door (110) is closed as the fan link (2200) rotates counterclockwise. When the door is closed, the driving device (210) pushes the push-pull rod again to position the connecting part (2110) at the first corner (2210). Accordingly, even if the user manually opens the closed door, no interference between parts occurs.

[0119] According to the various embodiments of the present disclosure as described above, the user may open or close the door automatically or manually. Although a door opening and closing device for an electronic device has been illustrated and described above, such a door opening and closing device (200) is not necessarily required to be used only in electronic devices and may be applied to furniture or other devices that use doors.

[0120] FIG. 25 is a flowchart illustrating a door control method of an electronic device according to various embodiments of the present disclosure.

[0121] According to FIG. 25, when an event occurs requiring the electronic device to open the door (S2510), the device moves the actuator in a first direction to open the door (S2520), and when the door is opened, moves the actuator to a position where the door can be manually closed (S2530). This series of processes is referred to as the door opening step or door opening operation. The above-described door opening step applies to cases where the user automatically opens the door, but separately, the user may also manually open the door.

[0122] When the door is open automatically or manually, if an event occurs requiring the door to be closed (S2540), the electronic device can close the door by moving the actuator in a second direction opposite to the first direction (S2550). Once the door is closed, the actuator is moved to a position where manual opening of the door is possible (S2560). This series of processes is referred to as the door closing step or door closing operation. The aforementioned door closing step applies to the case where the user automatically closes the door; separately, the user may also close the door manually.

[0123] In other words, according to the various embodiments of the present disclosure as described above, the user may open or close the door automatically or manually. Accordingly, the door can be opened or closed without issue even in the event of a power outage. Furthermore, the product is not damaged even if the user accidentally operates the door manually.

[0124] The door control method described in FIG. 25 can be performed in an electronic device implemented with a structure according to the various embodiments described above. Events for opening the door, events for closing the door, actuators, link members, etc., can be implemented according to the contents described in the various embodiments described above.
