Description

Cushion structure and wearable electronic device including same

[0001] Various embodiments of this document relate to wearable electronic devices corresponding to head-mounted devices with improved wearability.

[0002] Recently, wearable electronic devices, designed to be worn directly on the human body, have been developed and are becoming widespread. These wearable electronic devices include head-mounted displays (or head-mounted devices), smart glasses, and smart watches or wristbands, and are being developed in a variety of forms.

[0003] For example, head-mounted electronic devices (e.g., head-mounted displays) are electronic devices that are worn on the user's head in the form of glasses, a hat, a helmet, etc., and include a display that is viewed through the structure. Because of their excellent portability, they are being widely used to implement virtual reality (VR) and augmented reality (AR). For example, head-mounted electronic devices can provide users with VR content corresponding to exhibits and materials displayed in places such as museums, art galleries, and exhibition halls. Alternatively, head-mounted electronic devices can provide various VR contents. Since such head-mounted electronic devices can provide a wide screen through a small display device, the user's sense of presence and satisfaction is high.

[0027] Hereinafter, various embodiments of this document may be described with reference to the attached drawings.

[0028] An embodiment of the present disclosure described below relates to a wearable electronic device, and as an example, relates to a head-mounted wearable electronic device (e.g., a head-mounted display, a head-mounted device). The head-mounted wearable electronic device of the present disclosure (hereinafter, referred to as a wearable electronic device) provides a structure that allows a user to more stably maintain a wearing state. Compared to devices such as smart glasses, the wearable electronic device is larger and heavier, and may generate movement depending on the movement of the user's head after being worn. The generation of movement may hinder a feeling of wearing and make it difficult to continuously view content. The wearable electronic device according to an embodiment of the present disclosure may provide a structure that suppresses the generation of movement, for example, a tightening structure that corresponds to various user head shapes.

[0029] For example, a wearable electronic device according to an embodiment of the present disclosure may provide a structure capable of deforming at least a portion of a cushion structure in contact with a user's forehead (or front of the face, forehead) according to manipulation. Based on this, the wearable electronic device according to an embodiment of the present disclosure may provide a closer contact state or high adhesion between the user's forehead and the cushion structure regardless of various user head shapes, thereby suppressing or reducing movement of the device while being worn, enhancing a wearing comfort, and supporting the absence of discomfort even when worn for a long time.

[0030] Hereinafter, various purposes and effects provided by cushion structures and wearable electronic devices including the same according to various embodiments may be mentioned according to embodiments of the detailed description. In the following description, a structure in which the cushion structure is arranged on the main body (e.g., the part where the display is arranged) of the wearable electronic device is exemplified, but the present disclosure is not limited thereto. For example, a cushion structure capable of partial shape deformation according to one embodiment may be arranged on at least one of the main body and the wearing part of the wearable electronic device. A description related to this will be described with reference to the drawings described below.

[0031] FIG. 1 is a drawing showing an example of the appearance of a wearable electronic device according to one embodiment.

[0032] Referring to FIG. 1, a wearable electronic device (103) (or head-mounted device, head-mounted wearable electronic device, hereinafter referred to as a wearable electronic device) according to one embodiment may include a main body (110) (or front end, front assembly, display assembly, main body structure, main body) and a wearing part (120) (or rear end, rear assembly, wearing assembly, wearing structure).

[0033] The above main body (110) may include a main body front part (110_fr) (or main body front case, first main body case), a main body rear part (110_rr) (or main body rear case, second main body case), a main body upper part (110_up) (or main body upper case, third main body case), a main body lower part (110_lo) (or main body lower case, fourth main body case), a first main body side part (112a) (or a first protrusion, a first support part, a first main body fastening part, a first main body extension part, or a first side part), a second main body side part (112b) (or a second protrusion, a second support part, a second main body fastening part, a second main body extension part, or a second side part), a first display structure (110_lf), a second display structure (110_rt), a first cushion structure (200) (or a first wearing support structure, a front structure, a front cushion structure, a first support part, a front support part).

[0034] The front part of the main body (110_fr) may include at least a portion of a case (or housing, frame) arranged in the -y-axis direction. At least a portion of the front part of the main body (110_fr) may be formed of a material having a certain rigidity, for example, a metal material or a plastic structure. However, the embodiment of the present disclosure is not limited to the material of the main body (110), and may include various materials or various structures that can withstand a certain amount of pressure or impact applied from the outside while having a weight according to the design standard, and may be configured in a composite manner or configured with a single material. Various sensors may be arranged on the front part of the main body (110_fr). For example, a camera sensor and an illuminance sensor may be arranged on the front part of the main body (110_fr). In addition, a microphone or a speaker may be arranged on the front part of the main body (110_fr). The front part of the main body (110_fr) may have a structure that can block or reduce light inflow from the outside.

[0035] The rear part (110_rr) of the main body may be positioned at a predetermined distance from the front part (110_fr) of the main body. For example, the rear part (110_rr) of the main body may be positioned in a direction opposite to the direction in which the front part (110_fr) of the main body faces. At least a portion of the rear part (110_rr) of the main body may be positioned at a position facing the face of the user when the user wears the wearable electronic device (103). At least a portion of the first display structure (110_lf) and the second display structure (110_rt) may be positioned on at least a portion of the rear part (110_rr) of the main body.

[0036] Between the front part (110_fr) of the main body and the rear part (110_rr) of the main body, various internal elements related to the operation of the wearable electronic device (103) may be arranged. For example, at least a part of the first display structure (110_lf) and the second display structure (110_rt) may be arranged between the front part (110_fr) of the main body and the rear part (110_rr). For example, a first display device arranged so that a first screen can be viewed through a first lens included in the first display structure (110_lf), and a second display device arranged so that a second screen can be viewed through a second lens included in the second display structure (110_rt) may be arranged in a part of the space between the front part (110_fr) of the main body and the rear part (110_rr). Here, the first display device and the second display device may be implemented as one display device and then configured to output two separate screens. Additionally or alternatively, various circuit elements related to driving a display device, a printed circuit board on which circuit elements are arranged, and a power supply unit (e.g., at least a part of a battery or an external power connection interface) for supplying power to the printed circuit board may be arranged between the front side (110_fr) of the main body and the rear side (110_rr) of the main body.

[0037] The upper part (110_up) of the main body and the lower part (110_lo) of the main body are arranged at the edge between the front part (110_fr) of the main body and the rear part (110_rr) of the main body, so that a certain space between the front part (110_fr) of the main body and the rear part (110_rr) can be closed. In this regard, a part of the upper part (110_up) of the main body can be connected to the upper part of the front part (110_fr) of the main body and the upper part of the rear part (110_rr) of the main body, and another part of the upper part (110_up) of the main body can be connected to parts of the lower part (110_lo) of the main body. A part of the lower part of the main body (110_lo) may be connected to the lower part of the front part (110_fr) of the main body and the lower part of the rear part (110_rr) of the main body, similarly to the upper part of the main body (110_up), and another part of the lower part of the main body (110_lo) may be connected to both sides of the upper part of the main body (110_up). An input device capable of generating a user input in relation to the operation of the wearable electronic device (103) may be arranged on at least one of the upper part of the main body (110_up) and the lower part of the main body (110_lo). In addition, a speaker or a microphone may be arranged on at least a part of the upper part of the main body (110_up) and the lower part of the main body (110_lo). Meanwhile, the wearable electronic device (103) of the present disclosure is not limited to the position or number of at least one of the above-described input devices, microphones and speakers, and various sensors, and at least one may be arranged at various positions of the main body (110) depending on a change in the design method or the purpose of the developer.

[0038] According to one embodiment, the first main body side (112a) and the second main body side (112b) may be respectively coupled or integrated with one side and the other side of the main body upper part (110_up). The drawing currently illustrated illustrates a form in which the main body upper part (110_up) and the first main body side (112a) and the second main body side (112b) are integrated. As an example, a communication interface and an input unit may be arranged on at least one of the first main body side (112a) or the second main body side (112b). When an electronic element (e.g., at least one of a memory, a communication interface, an input unit, and a control unit) is disposed on at least one of the first body side (112a) or the second body side (112b), the wearable electronic device (103) may further include wiring (or a PCB) disposed between the body upper part (110_up) and the first body side (112a) or the body upper part (110_up) and the second body side (112b).

[0039] The first main body side portion (112a) may be arranged to extend in a first direction (e.g., in the y-axis direction) from one edge (e.g., an edge in the x-axis direction) of the main body upper portion (110_up). The second main body side portion (112b) may be arranged to protrude in one direction (e.g., in the y-axis direction) from the other edge (e.g., an edge in the -x-axis direction) of the main body upper portion (110_up). The first main body side portion (112a) and the second main body side portion (112b) may be arranged parallel to each other based on an imaginary line in the y-axis direction that crosses the center of the -x-axis and the x-axis of the exterior of the wearable electronic device (103), and may be arranged to be spaced apart from each other by the length in the x-axis (or -x-axis) direction of the wearable electronic device (103). At least a portion of each of the first main body side portion (112a) and the second main body side portion (112b) may include a curved surface. For example, at least a portion of the first main body side portion (112a) facing the left side of the user's head may include a curved surface that is convex in the -x-axis direction from the x-axis, and at least a portion of the second main body side portion (112b) facing the right side of the user's head may include a curved surface that is convex in the -x-axis direction from the x-axis. An elastic material or a cushion structure may be disposed on the inner side of the first main body side portion (112a) (e.g., one side in the direction of the surface facing the -x-axis direction) and the inner side of the second main body side portion (112b) (e.g., one side in the direction of the surface facing the x-axis direction).

[0040] According to one embodiment, assuming that the user is wearing the wearable electronic device (103) and is looking at the -y axis, at least a portion of the first body side portion (112a) may be positioned on the left side of the user's head, and at least a portion of the second body side portion (112b) may be positioned on the right side of the user's head. As an example, at least a portion of the inner curved surface of the first body side portion (112a) (e.g., the surface facing the left side of the user's head) may be positioned to face the inner curved surface of the second body side portion (112b) (e.g., the surface facing the right side of the user's head). At least a portion of the first body side portion (112a) and the second body side portion (112b) may be formed of the same or similar material as the body upper portion (110_up). Alternatively, the first main body side portion (112a) and the second main body side portion (112b) may be formed of a material having higher rigidity than the main body upper portion (110_up). According to one embodiment, the first main body side portion (112a) may be coupled with the first wearing side portion (122a) of the wearing portion (120), and the second main body side portion (112b) may be coupled with the second wearing side portion (122b) of the wearing portion (120).

[0041] The first display structure (110_lf) may be positioned at a position aligned with one side of the user's field of vision when the user wears the wearable electronic device (103). For example, when the wearable electronic device (103) is worn, the first display structure (110_lf) may be positioned at a position aligned with the user's left eye. The first display structure (110_lf) may include a first lens, a first barrel on which the first lens is positioned, and a first display device positioned at one end of the first barrel.

[0042] The second display structure (110_rt) may be positioned at a position aligned with the other side of the user's field of vision when the user wears the wearable electronic device (103). For example, when the wearable electronic device (103) is worn, the second display structure (110_rt) may be positioned at a position aligned with the user's right eye. The second display structure (110_rt) may include a second lens, a second barrel on which the second lens is positioned, and a second display device positioned at one end of the second barrel.

[0043] The first display device and the second display device can output stored content or content provided from an external source. In this regard, the wearable electronic device (103) may include a memory capable of storing content, a communication interface capable of receiving content, an input unit (or input module, input means, input device) for user input, and a control unit. The control unit may include a memory, a communication interface, an input unit, and at least one hardware processor that controls the first display device and the second display device.

[0044] The first cushion structure (200) may be arranged on one side of the main body (110). For example, the first cushion structure (200) may be arranged to be detachably attached to an area (e.g., structure placement area (110_at) (or front mounting portion, step portion)) of the upper portion (110_up) of the main body. According to one embodiment, the first cushion structure (200) may include a hook coupling structure that may be coupled with a hook mounting structure arranged in the structure placement area (110_at). However, the present disclosure is not limited thereto, and the first cushion structure (200) and the structure placement area (110_at) may be coupled through a screw coupling or another coupling structure (e.g., rail coupling). The first cushion structure (200) may be partially deformed in response to a user operation. For example, the first cushion structure (200) may have at least one portion (e.g., the center, or the center of the structure observed in the y-axis direction, or the center area among the portions that come into contact with a part of the user's body when worn) deform in the y-axis direction or the -y-axis direction in response to a user operation. Based on this, the first cushion structure (200) can stably fix the main body (110) to the user's body and improve the generation of flow by closely contacting the user's body regardless of the shape or form of the user's forehead.

[0045] The above-mentioned wearing part (120) may include a first wearing side (122a) (or a first strap, a first mounting part, a third side, a first connecting part, a first fastening part), a second wearing side (122b) (or a second strap, a second mounting part, a fourth side, a second connecting part, a second fastening part), a connecting structure (122c), an adjusting device (130) (or an adjusting part, an adjusting structure, an adjusting member, an adjusting means), and a second cushion structure (150) (or a second wearing support structure, an occipital cushion structure, a rear structure, a second support part, a rear support part).

[0046] One side (e.g., -y-axis edge) of the first wearing side (122a) can be coupled with the first main body side (112a). One side (e.g., -y-axis edge) of the second wearing side (122b) can be coupled with the second main body side (112b).

[0047] The above-mentioned connecting structure (122c) is arranged between the other side (y-axis edge) of the first wearing side (122a) and the other side (y-axis edge) of the second wearing side (122b), and can connect the first wearing side (122a) and the second wearing side (122b). The connecting structure (122c) can be formed as a single body with the first wearing side (122a) and the second wearing side (122b). Alternatively, the connecting structure (122c) can be formed as a structure physically separated from the first wearing side (122a) and the second wearing side (122b), and then assembled with the first wearing side (122a) and the second wearing side (122b). The thickness (e.g., y-axis thickness) of the connection structure (122c) may be formed to be thicker than the thicknesses (e.g., x-axis thickness) of the first wearing side (122a) and the second wearing side (122b). At least a portion of the adjusting device (130) may be arranged on the outer side of the connection structure (122c), and a second cushion structure (150) may be arranged on the inner side of the connection structure (122c).

[0048] The above-described adjusting device (130) may include a dial device disposed on one side of the connecting structure (122c), and a sliding device (or shaft) that can change the arrangement state of the second cushion structure (150) while being connected to the dial device. As an example, the adjusting device (130) may be disposed at a point (e.g., the center, or the center on the x-axis and y-axis) of the connecting structure (122c). The dial device of the adjusting device (130) may be rotated clockwise or counterclockwise. The sliding device connected to the dial device may include a pillar portion having a gear pattern (or screw pattern) formed thereon that meshes with the gear pattern (or screw pattern) of the dial device. The sliding device may be moved in the -y-axis direction or in the y-axis direction in response to the rotation of the dial device. For example, when the dial device rotates counterclockwise (or clockwise), the sliding device may move in the -y-axis direction to advance (or move) the second cushion structure (150) in the -y-axis direction. When the dial device is rotated clockwise (or counterclockwise), the sliding device can move in the y-axis direction to retract (or move) the second cushion structure (150) in the y-axis direction.

[0049] As described above, the wearable electronic device (103) according to one embodiment of the present disclosure can support a user's body contact more closely and strongly by supporting a shape deformation of at least a portion of the first cushion structure (200) (e.g., at least a portion including the center of the first cushion structure (200). The structure of the first cushion structure (200) described below can be equally applied to the second cushion structure (150) as mentioned above. In addition, the structure of the adjustment device (130) applied to the second cushion structure (150) can also be equally applied to the first cushion structure (200).

FIG. 3 is a drawing showing a second directional shape of an embodiment of the exterior of a main body of a wearable electronic device according to one embodiment.

[0051] Referring to FIGS. 2 and 3, a wearable electronic device (103) according to one embodiment may be an example of the wearable electronic device (103) of FIG. 1. An example of the appearance of a first side (310) of a housing of the wearable electronic device (103) according to one embodiment may be illustrated in FIG. 2, and an example of the appearance of a second side (320) opposite to the first side (310) may be illustrated in FIG. 3.

[0052] Referring to FIG. 2, according to one embodiment, a first surface (310) of a wearable electronic device (103) may have an attachable or mountable form on a body part of a user (e.g., the face or head of the user). Although not shown, the wearable electronic device (103) may further include a strap for fixing on a body part of a user, and / or one or more temples (e.g., the body side parts (112a, 112b) and the wearing part (120) of FIG. 1). A first display (250-1) for outputting an image to a left eye among the user's two eyes (e.g., the first display structure (110_lf) of FIG. 1) and a second display (250-2) for outputting an image to a right eye among the user's two eyes (e.g., the second display structure (110_rt) of FIG. 1) may be disposed on the first surface (310). The wearable electronic device (103) may further include a rubber or silicone packing formed on the first surface (310) to prevent or reduce interference by light (e.g., ambient light) different from the light emitted from the first display (250-1) and the second display (250-2).

[0053] According to one embodiment, a wearable electronic device (103) may include cameras (260-1) for photographing and / or tracking both eyes of a user adjacent to each of the first display (250-1) and the second display (250-2). The cameras (260-1) may include a gaze tracking camera (260-1). According to one embodiment, a wearable electronic device (103) may include cameras (260-5, 260-6) for photographing and / or recognizing a face of a user. The cameras (260-5, 260-6) may be referred to as focus tracking (FT) cameras. The wearable electronic device (103) may control an avatar representing the user in a virtual space based on the motion of the user's face identified using the cameras (260-5, 260-6). For example, the wearable electronic device (103) may change the texture and / or shape of a portion of an avatar (e.g., a portion of an avatar representing a human face) using information obtained by cameras (260-5, 260-6) (e.g., FT cameras) and representing a facial expression of a user wearing the wearable electronic device (103).

[0054] Referring to FIG. 3, a camera (e.g., cameras 260-7, 260-8, 260-9, 260-10, 260-11, 260-12)) and / or a sensor (e.g., a depth sensor (330)) for obtaining information related to the external environment of the wearable electronic device (103) may be disposed on a second surface (320) opposite to the first surface (310) of FIG. 3. For example, the cameras (260-7, 260-8, 260-9, 260-10) may be disposed on the second surface (320) to recognize external objects. The cameras (260-7, 260-8, 260-9, 260-10) may include a motion recognition camera.

[0055] For example, using cameras (260-11, 260-12), the wearable electronic device (103) can obtain images and / or videos to be transmitted to each of the user's eyes. The camera (260-11) can be disposed on the second face (320) of the wearable electronic device (103) to obtain an image to be displayed through the second display (250-2) (e.g., the second display structure (110_rt) of FIG. 1) corresponding to the right eye among the two eyes. The camera (260-12) can be disposed on the second face (320) of the wearable electronic device (103) to obtain an image to be displayed through the first display (250-1) (e.g., the second display structure (110_rt) of FIG. 1) corresponding to the left eye among the two eyes. For example, a wearable device (103) can obtain a single screen using multiple images obtained through cameras (260-11, 260-12).

[0056] According to one embodiment, the wearable electronic device (103) may include a depth sensor (330) disposed on the second face (320) to identify a distance between the wearable electronic device and an external object. Using the depth sensor (330), the wearable electronic device (103) may obtain spatial information (e.g., a depth map) for at least a portion of a field of view (FoV) of a user wearing the wearable electronic device (103). Although not illustrated, a microphone may be disposed on the second face (320) of the wearable electronic device (103) to obtain a sound output from an external object. The number of microphones may be one or more, depending on the embodiment.

[0057] FIG. 4 is a drawing showing an example of a wearable electronic device with a first cushion structure disassembled according to one embodiment. FIG. 5 is a drawing showing an example of an exploded perspective view of a first cushion structure in a first direction according to one embodiment. FIG. 6 is a drawing showing an example of an exploded perspective view of a first cushion structure in a second direction according to one embodiment.

[0058] Referring to FIGS. 1 to 6, a wearable electronic device (103) according to an embodiment includes a main body (110) and a wearing part (120). A display structure (110_dsp) (e.g., a structure including the first display structure (110_lf) and the second display structure (110_rt) described above in FIG. 1) is disposed inside the main body (110), and a second cushion structure (150) may be disposed on one side of the wearing part (120). An upper portion (110_up) of the main body (110) may include a structure arrangement area (110_at) to which a first cushion structure (200) is coupled. In the above structure arrangement area (110_at), a driving device (210) (or a structure coupling portion (210_co) (or a structure coupling device, coupling portion, or structure fastening portion) among the driving devices (210)) arranged in the first cushion structure (200) can be coupled and fixed. The structure of the main body (110) and the wearing portion (120) described in FIG. 4 may be the same as or similar to the main body and the wearing portion configuration described in FIG. 1. Accordingly, the description of the main body (110) and the wearing portion (120) may be replaced with or supplemented by the description of the main body (110) and the wearing portion (120) described in FIG. 1.

[0059] The first cushion structure (200) may include a driving device (210) (or a pressurizing structure, a pressurizing device, an operating device) and a bracket structure. The bracket structure (e.g., at least one of 220, 230, 240a, 240b, 250a, 250b, 250c, 260) may include a support bracket (220) (or a support panel, a support cover, a support case, a first bracket), a cushion bracket (230) (or a flexible panel, a flexible cover, a flexible case, a second bracket, a deformable bracket, an elastic bracket), and a pad portion (260) (or a cushion pad, a cushion). Additionally or alternatively, the driving device (210) may include a first bracket fixing portion (240a) (or first sliding fixing portion, first support bracket fastening portion) and a second bracket fixing portion (240b) (or second sliding fixing portion, second support bracket fastening portion) used to allow a portion of the cushion bracket (230) to slide when the cushion bracket (230) is deformed relative to the support bracket (220). In addition, the driving device (210) may further include a first fastening portion (250a) (or a first screw, a first screw, a first fixing pin) and a second fastening portion (250b) (or a second screw, a second screw, a second fixing pin) used to fasten the first bracket fixing portion (240a) and the second bracket fixing portion (240b) to the support bracket (220), and a third fastening portion (250c) used to fasten at least a portion of the cushion bracket (230) to a portion of the driving device (210).

[0060] The above driving device (210) may include at least a part of a driving body (210_ba) (or a pressurized body, a driving case, a pressurized case, a case, a housing, a frame), a driving part (210_di) (or a dial, a dial structure, a dial device, a pressurized part, a drive module), a moving part (210_ph) (or a column part, a pressurized column, a pressurized rod, a pressurized base), and a structure connecting part (210_co).

[0061] The driving body (210_ba) may include an empty space on the inside in which at least a part of the driving unit (210_di) and at least a part of the moving unit (210_ph) can be arranged. For example, the driving body (210_ba) may include a structure in which an upper case and a lower case are coupled vertically or a left case or a right case is coupled horizontally, thereby forming an empty space in the center. The front structure of the driving body (210_ba) (e.g., a structure in the direction of the front part of the body (e.g., the front part (110_fr) of the body in FIG. 1)) may be closed so that the internal empty space is not observed. The rear structure of the driving body (210_ba) (e.g., a structure in the direction of the rear part (110_rr) of the body in FIG. 1)) may include a structure that is opened in the y-axis direction for the movement of the moving unit (210_ph) (e.g., an opening (210_ba_op) or a gate, a moving hole). According to one embodiment, a hole (210_ba_h) (or driving part hole) may be formed on the upper portion of the driving body (210_ba) so that at least a portion of the driving part (210_di) may be exposed to the outside or protrude (or exposed) to the outside (e.g., outward from the upper surface). The size of the hole (210_ba_h) may be smaller than the size of the driving part (210_di) in at least one direction so as to prevent the driving part (210_di) from being separated from the inside of the driving body (210_ba).

[0062] A joining region where a driving unit (210_di) and a moving unit (210_ph) are combined may be arranged in the empty space inside the driving body (210_ba). In response to the operation of the driving unit (210_di), the size of the moving unit (210_ph) placed (or arranged) inside the driving body (210_ba) may change. The driving body (210_ba) may be formed of the same material as at least a portion of the materials of the main body (110) and the wearing unit (120). According to one embodiment, the driving body (210_ba) may include a metal material or a plastic structure having a rigidity of a certain size or more. As an example, the x-axis length of the driving body (210_ba) may be formed longer than the y-axis length, and the x-axis length may be formed longer than the z-axis length. Alternatively, the y-axis length of the driving body (210_ba) may be formed longer than the z-axis length. The z-axis length (or thickness) of the driving body (210_ba) may vary depending on the location. According to various embodiments, at least a portion of the driving body (210_ba) may be formed of a material such as transparent plastic.

[0063] The above driving unit (210_di) may include a structure capable of moving the moving unit (210_ph) according to a user operation. For example, the driving unit (210_di) may include a dial device and a shaft having a gear pattern (or a screw pattern) formed thereon. The driving unit (210_di) may move the moving unit (210_ph) coupled with the shaft in the y-axis direction or the -y-axis direction in response to a user operation (e.g., an operation of rotating the dial). In this regard, at least a portion of the driving unit (210_di) may be exposed or protruded to the outside (e.g., protrude further outward than the upper surface of the driving unit (210_ba)) through a hole (210_ba_h) formed at the upper end of the driving body (210_ba). The dial device of the driving unit (210_di) may have a groove pattern or a wrinkle pattern formed on at least a portion of the edge in relation to the user operation. At least a part of the driving unit (210_di) may be formed of a material or structure having higher rigidity than the driving body (210_ba). For example, at least a part of the portion where the driving unit (210_di) is coupled to the moving unit (210_ph) may be formed of a metal material. Meanwhile, in the embodiment of the present disclosure, a structure in which the moving unit (210_ph) is moved by a user's manual operation (e.g., rotational operation of a dial device) is exemplified, but the present disclosure is not limited thereto. For example, as an embodiment, the driving unit (210_di) may include a motor and a button for controlling motor operation, and according to the operation of the button, the power generated by the motor may be converted into a linear movement (e.g., movement in the -y-axis and y-axis directions) of the moving unit (210_ph) connected to the motor.

[0064] The above-described moving part (210_ph) can move linearly in the y-axis or -y-axis direction depending on the operation of the driving part (210_di). For example, the moving part (210_ph) may have a gear structure that can convert the rotational motion of the driving part (210_di) into linear motion. For example, when the driving part (210_di) rotates clockwise (or counterclockwise), the moving part (210_ph) can move in the y-axis direction (or -y-axis direction). The moving part (210_ph) may include a part that is coupled with the driving part (210_di) and a part that is coupled with (or in contact with) the cushion bracket (230). The moving part (210_ph) may be formed of a material or structure that has higher rigidity than the driving body (210_ba). For example, at least a portion of the portion where the moving part (210_ph) is coupled to the driving part (210_di) may be formed of a metal material. At least a portion of the portion where the moving part (210_ph) and the cushion bracket (230) are coupled may be formed of a plastic structure.

[0065] At least a portion of the support bracket (220) may be disposed between the driving device (210) and the cushion bracket (230). For example, one side of the support bracket (220) may be coupled with the driving device (210), and the other side of the support bracket (220) may be coupled with the cushion bracket (230). According to one embodiment, the support bracket (220) includes a first bracket body (220_ba) (or a first frame, a first case, a first housing), a first bracket connection part (220_bos1), and a second bracket connection part (220_bos2), and the first bracket body (220_ba) may include a bracket front end part (220_bar) and a bracket rear end part (220_baf).

[0066] The above bracket front end (220_bar) may include a portion used for coupling with the driving device (210). In this regard, the bracket front end (220_bar) may include a frame forming a device insertion hole (220_hco) formed in the -y-axis direction. The size of the device insertion hole (220_hco) may be formed to be the same as or similar to at least a portion of the exterior of the driving device (210). When one side of the driving device (210) is inserted into the device insertion hole (220_hco) of the bracket front end (220_bar), the inner side of the bracket front end (220_bar) and one side (e.g., the outer surface of the y-axis edge) of the driving body (210_ba) of the driving device (210) may be arranged to engage with each other. In this regard, a step portion may be provided in a belt shape on one side of the driving body (210_ba), and the -y-axis edge of the bracket front end (220_bar) may be arranged to face (or come into contact with) the step portion of the driving body (210_ba).

[0067] The rear end (220_baf) of the bracket may include a portion extending in the y-axis direction from the front end (220_bar) of the bracket. The rear end (220_baf) of the bracket may have a funnel shape that gradually increases in the y-axis direction from the -y-axis. The shape of the outlet (e.g., the edge in the y-axis direction) of the rear end (220_baf) of the bracket may have a shape corresponding to the shape of the cushion bracket (230). The rear end (220_baf) of the bracket may be formed to have a left-right symmetrical structure based on the center of the -x-axis and the x-axis. The y-axis length of the upper end of the rear end (220_baf) of the bracket may be formed to be longer than the y-axis length of the lower end of the rear end (220_baf). As an example, the rear end of the bracket (220_baf) may include an upper end facing the upper end of the cushion bracket (230), a lower end facing the lower end of the cushion bracket (230), a first side facing one edge of the cushion bracket (230), and a second side facing the other edge of the cushion bracket (230). The upper end, lower end, first and second sides of the rear end of the bracket (220_baf) may be connected to each other to form a belt shape. While the cushion bracket (230) is placed (or coupled) to the rear end of the bracket (220_baf), an edge (e.g., a y-axis edge) of the rear end of the bracket (220_baf) may be placed to surround the rim of the cushion bracket (230). A first bracket connecting portion (220_bos1) and a second bracket connecting portion (220_bos2) may be arranged on the inner side of the first side and the inner side of the second side, respectively, of the rear end of the above bracket (220_baf).

[0068] The first bracket connecting portion (220_bos1) may protrude in the y-axis direction from one inner surface of the first side of the rear end portion (220_baf) of the bracket. As an example, the first bracket connecting portion (220_bos1) may include a boss (or protrusion) that can be fastened with a screw or screw. As an example, the first bracket connecting portion (220_bos1) may have a protruding structure that forms a hollow groove in the center and protrudes in the y-axis direction, and a female screw thread pattern may be formed on the inner wall of the groove.

[0069] The second bracket connecting portion (220_bos2) may protrude from the inner surface of the second side of the rear end portion (220_baf) of the bracket so as to face the y-axis direction. The second bracket connecting portion (220_bos2) may be arranged symmetrically with respect to the center portion of the x-axis and the -x-axis with respect to the first bracket connecting portion (220_bos1). The shape of the second bracket connecting portion (220_bos2) may be formed to be the same as the shape of the first bracket connecting portion (220_bos1). As an example, the second bracket connecting portion (220_bos2) may include a boss (or protrusion) capable of being fastened with a screw or a screw. The second bracket connecting portion (220_bos2) may have a protruding structure that forms a hollow groove in the center and protrudes in the y-axis direction, and a female screw thread pattern may be formed on the inner wall of the groove.

[0070] At least a portion of the cushion bracket (230) may be disposed between the support bracket (220) and the pad portion (260). For example, one edge of the cushion bracket (230) (e.g., the first edge (230_sd1) of the cushion bracket (230)) may be coupled with one edge of the support bracket (220) (e.g., the first edge (220_sd1) of the support bracket (220)), and the other edge of the cushion bracket (230) (e.g., the second edge (230_sd2) of the cushion bracket (230)) may be coupled with the other edge of the support bracket (220) (e.g., the second edge (220_sd2) of the support bracket (220)). The center of the cushion bracket (230) may be coupled with the moving portion (210_ph) of the driving device (210). According to one embodiment, the cushion bracket (230) may include a second bracket body (230_ba) (or a second frame, a second case, a second housing), a first sliding hole (230_h1), a second sliding hole (230_h2), and a bracket fixing hole (230_hc) formed in the second bracket body (230_ba).

[0071] The second bracket body (230_ba) may be formed such that the length in the horizontal direction (e.g., the x-axis or -x-axis direction) is longer than the length in the vertical direction (e.g., the z-axis or -z-axis direction). The second bracket body (230_ba) may have a length in the z-axis direction that becomes shorter as it goes toward one edge (e.g., the edge in the left direction (e.g., the -x-axis direction)) or the other edge (e.g., the edge in the right direction (e.g., the x-axis direction)) from the center (e.g., the part where the bracket fixing hole (230_hc) is arranged). The second bracket body (230_ba) may have a curvature that increases (or the degree of bending that increases) as it goes from the center to one edge. Alternatively, the curvature of the center of the second bracket body (230_ba) may be smaller (or may be gentler) than the curvature of the edge of the second bracket body (230_ba).

[0072] The center of the second bracket body (230_ba) may be formed to be convex in the y-axis direction from the -y-axis direction (or from the wearing part (120) to the body part (110) direction). For example, when viewed from the body part (110) direction, the center of the second bracket body (230_ba) may be formed to be convex in the direction of the body part (110), and when viewed from the wearing part (120) direction, the center of the second bracket body (230_ba) may be formed to be concave in the direction of the body part (110). The second bracket body (230_ba) may have the same or similar size as the y-axis direction edge of the bracket rear end (220_baf) of the support bracket (220). The second bracket body (230_ba) may be formed of a different material from the support bracket (220). For example, at least a portion of the second bracket body (230_ba) may be formed of a material having higher elasticity (or ductility) than the support bracket (220). As an example, the second bracket body (230_ba) may include a plastic structure having a first characteristic, and the support bracket (220) may include a plastic structure having a second characteristic, wherein the second characteristic may include a characteristic having lower elasticity (or ductility) than the first characteristic.

[0073] One side and the other side edges (e.g., the first edge (230_sd1) and the second edge (230_sd2)) of the second bracket body (230_ba) can be mounted on the first bracket fixing part (240a) and the second bracket fixing part (240b) (or one side and the other side of the support bracket (220). The center of the second bracket body (230_ba) can be coupled with the moving part (210_ph) of the driving device (210). The center of the second bracket body (230_ba) can be bent in the y-axis direction (or the direction of the wearing part (120)) or in the -y-axis direction (or the body part (110)) according to the movement of the moving part (210_ph). Alternatively, in the absence of a separate external pressure (e.g., pressurization by the moving part (210_ph)), the center of the second bracket body (230_ba) remains bent in the -y-axis direction, and the bent state of the center may be changed by the pressurization of the moving part (210_ph). For example, the curvature of the center of the second bracket body (230_ba) may be reduced (e.g., the center may become flatter than before, or the degree of bending may be reduced and the degree of flatness may be increased) by the pressurization of the moving part (210_ph).

[0074] The second bracket body (230_ba) is formed on one side (e.g., a side facing the -y-axis direction or the body part (110), a side facing the display structure), and may include a first mounting portion (230_r1) (or a first boss groove, a first insertion groove) and a second mounting portion (230_r2) (or a second boss groove, a second insertion groove) on which at least a part of the moving part (210_ph) is mounted.

[0075] The first mounting portion (230_r1) may protrude from a point (e.g., center) on one side of the second bracket body (230_ba) toward the body portion (110) and may include an empty groove in the center. At least a part of the moving portion (210_ph) may be inserted and mounted in the first mounting portion (230_r1) (or empty groove). As an example, the size of the groove of the first mounting portion (230_r1) may be formed to be the same as or similar to the size of at least a part of the protruding portion of the moving portion (210_ph) to be inserted and mounted. The above first mounting portion (230_r1) can prevent (or improve) the moving portion (210_ph) from moving away from a point on one side of the second bracket body (230_ba) or the movement of the moving portion (210_ph) while the moving portion (210_ph) presses the second bracket body (230_ba) in the y-axis direction.

[0076] The second mounting portion (230_r2) may protrude from another point on one side of the second bracket body (230_ba) toward the main body (110) and may include an empty groove in the center. The second mounting portion (230_r2) may have the same or similar shape and function as the first mounting portion (230_r1), except that it is positioned (or formed) at another point on one side of the second bracket body (230_ba) spaced apart from the first mounting portion (230_r1). As an example, at least another part of the moving portion (210_ph) may be inserted and mounted in the second mounting portion (230_r2) (or the empty groove). As an example, the size of the groove of the second mounting portion (230_r2) may be formed to be the same or similar to the size of at least a portion of the protruding part of the moving portion (210_ph) to be inserted and mounted. The second mounting portion (230_r2) can prevent (or improve) the moving portion (210_ph) from being dislodged from another point on one side of the second bracket body (230_ba) or the movement of the moving portion (210_ph) while the moving portion (210_ph) presses the second bracket body (230_ba) in the y-axis direction, together with the first mounting portion (230_r1). Meanwhile, in the embodiment of the present disclosure, a structure in which the second bracket body (230_ba) includes two first mounting portions (230_r1) and second mounting portions (230_r2) is exemplified, but the present disclosure is not limited thereto. For example, the second bracket body (230_ba) may have one mounting portion formed thereon or three or more mounting portions formed thereon. The number and shape of these mounting portions can be added, removed, or modified to correspond to the number and shape of the moving portion (210_ph) (e.g., the number and shape of pillar portions protruding from one end of the moving portion toward the cushion bracket (230).

[0077] The first sliding hole (230_h1) may be formed in a form (e.g., penetrating the -y axis and the y axis) that penetrates the front and rear surfaces of the second bracket body (230_ba) at one edge of the second bracket body (230_ba) (e.g., the first edge (230_sd1), or the left edge or the x-axis edge based on FIG. 6). The first sliding hole (230_h1) may be formed such that, for example, the length in the x-axis (or -x-axis) direction is longer than the length in the z-axis (or -z-axis) direction. According to one embodiment, the first sliding hole (230_h1) may be formed to be larger than the size of the first bracket connecting portion formed in the support bracket (220). Alternatively, the first sliding hole (230_h1) may be formed to be larger than the size of the portion of the first bracket fixing portion (240a) that protrudes in the direction of the support bracket (220). At least a portion of the first bracket connecting portion (220_bos1) formed on the support bracket (220) and the first bracket fixing portion (240a) fastened to the first bracket connecting portion (220_bos1) may be arranged in the first sliding hole (230_h1). The first sliding hole (230_h1) may guide movement of the first bracket fixing portion (240a) in the x-axis or -x-axis direction. As the first bracket fixing portion (240a) moves along the first sliding hole (230_h1), the degree of curvature of at least a portion of the second bracket body (230_ba) (e.g., the degree of curvature of at least a portion of the center of the second bracket body (230_ba) and the left edge (or the first edge (230_sd1)) based on FIG. 6) may be changed.

[0078] The second sliding hole (230_h2) may be formed in a shape that penetrates the front and rear surfaces of the second bracket body (230_ba) at the other edge of the second bracket body (230_ba) (e.g., the second edge (230_sd2), the right edge based on FIG. 5, or the -x-axis edge) (e.g., the shape that penetrates the -y-axis and the y-axis). Alternatively, the second sliding hole (230_h2) may be positioned symmetrically with respect to the first sliding hole (230_h1) with respect to the center of the second bracket body (230_ba). The second sliding hole (230_h2) may be formed in a shape identical to or similar to that of the first sliding hole (230_h1). For example, the second sliding hole (230_h2) may be formed such that the length in the x-axis (or -x-axis) direction is longer than the length in the z-axis (or -z-axis) direction. According to one embodiment, at least a portion of the second sliding hole (230_h2) may be larger than the second bracket connecting portion (220_bos2) formed in the support bracket (220). Alternatively, at least a portion of the second sliding hole (230_h2) may be larger than a portion of the second bracket fixing portion (240b) protruding toward the support bracket (220). At least a portion of the second bracket connecting portion (220_bos2) formed in the support bracket (220) and the second bracket fixing portion (240b) fastened to the second bracket connecting portion (220_bos2) may be arranged in the second sliding hole (230_h2). The second sliding hole (230_h2) may guide movement of the second bracket fixing portion (240b) in the -x-axis or x-axis direction. As the second bracket fixing part (240b) moves along the second sliding hole (230_h2), the degree of curvature of at least a portion of the second bracket body (230_ba) (e.g., the degree of curvature of at least a portion of the center of the second bracket body (230_ba) and the right edge (or second edge (230_sd2)) based on FIG. 5) can be changed.When the moving part (210_ph) presses the center of the second bracket body (230_ba), the first edge (230_sd1) (e.g., the left edge as shown in FIG. 6) of the second bracket body (230_ba) in which the first sliding hole (230_h1) is formed can move in a first direction (e.g., the x-axis direction), and the second edge (230_sd2) (e.g., the right edge as shown in FIG. 5) of the second bracket body (230_ba) in which the second sliding hole (230_h2) is formed can move in a second direction (e.g., the -x-axis direction). Alternatively, depending on the pressing of the moving part (210_ph), the first edge and the second edge can move in different directions (e.g., in a direction away from the center of the second bracket body (230_ba)). When the pressure of the above moving part (210_ph) is released, the first edge and the second edge can move in a direction facing each other (e.g., in a direction closer to the center of the second bracket body (230_ba)).

[0079] The bracket fixing hole (230_hc) may be formed to penetrate the front and rear surfaces of the second bracket body (230_ba) at a point of the second bracket body (230_ba) (e.g., an intersection of the center between the x-axis and the -x-axis and the center between the z-axis and the -z-axis, or an area including the intersection). At least a portion of the third fastening portion (250c) may be inserted into the bracket fixing hole (230_hc). The bracket fixing hole (230_hc) may be used to fix the second bracket body (230_ba) to the moving portion (210_ph) of the driving device (210). The bracket fixing hole (230_hc) may be arranged between the first mounting portion (230_r1) and the second mounting portion (230_r2).

[0080] The first bracket fixing portion (240a) (or the first sliding support structure, the first sliding structure, the first sliding fixing portion, the first support bracket fastening portion) may be coupled to the first bracket connecting portion (220_bos1) of the support bracket (220) while penetrating at least a portion of the first sliding hole (230_h1) formed in the cushion bracket (230). As an example, the first bracket fixing portion (240a) includes a hole into which the first fastening portion (250a) can be inserted, and may be fixed to the first bracket connecting portion (220_bos1) by the first fastening portion (250a) while being aligned with the first bracket connecting portion (220_bos1). The first bracket fixing member (240a) can support movement of the first edge (230_sd1) of the cushion bracket (230) (e.g., movement in the first direction or in the second direction opposite to the first direction) (or deformation of the first edge (230_sd1)).

[0081] The second bracket fixing portion (240b) (or the second sliding support structure, the second sliding structure) may be coupled with the second bracket connecting portion (220_bos2) of the support bracket (220) while penetrating at least a portion of the second sliding hole (230_h2) formed in the cushion bracket (230). As an example, the second bracket fixing portion (240b) includes a hole into which the second fastening portion (250b) may be inserted, and may be fixed to the second bracket connecting portion (220_bos2) by the second fastening portion (250b) while being aligned with the second bracket connecting portion (220_bos2). The second bracket fixing portion (240b) may be positioned symmetrically with respect to the first bracket fixing portion (240a) with respect to the center of the cushion bracket (230). The second bracket fixing member (240b) can support movement of the second edge (230_sd2) of the cushion bracket (230) (e.g., movement of the second edge in the second direction or the first direction) (or deformation of the second edge (230_sd2)).

[0082] The above fastening parts (250a, 250b, 250c) may include a first fastening part (250a) that supports fastening of the first bracket fixing part (240a), a second fastening part (250b) that supports fastening of the second bracket fixing part (240b), and a third fastening part (250c) that supports fastening of the cushion bracket (230) and the moving part (210_ph). The above fastening parts (250a, 250b, 250c) may have the same material or size. As an example, the above fastening parts (250a, 250b, 250c) may include a screw or a male screw (bolt).

[0083] The pad portion (260) may be arranged to cover at least a portion of another side of the cushion bracket (230) (e.g., a side facing the y-axis direction or a side facing the wearing part (120). The pad portion (260) may be fixed or adhered to the other side of the cushion bracket (230). According to one embodiment, the pad portion (260) may include a first pad portion (260_rr) (or front pad portion) facing the cushion bracket (230) and a second pad portion (260_fr) (or rear pad portion) coming into contact with a part of the user's body. The size and shape of the first pad portion (260_rr) and the second pad portion (260_fr) may be the same or similar.

[0084] According to one embodiment, the materials of the first pad portion (260_rr) and the second pad portion (260_fr) may be different. For example, at least a portion of the second pad portion (260_fr) may be composed of breathable fabric, a first polymer material, or a fiber material. Alternatively, at least a portion of the first pad portion (260_rr) may be composed of sponge, rubber, or a second polymer material (e.g., a material having higher elasticity than the first polymer material). Alternatively, the pad portion (260) may be formed of the same material without separate portions. Alternatively, at least a portion of the interior of the pad portion (260) may be formed of sponge or rubber, and at least a portion of the exterior of the pad portion (260) may be formed of fabric. Additionally or alternatively, an adhesive layer (or adhesive member) for adhesion to the cushion bracket (230) may be disposed on the first pad portion (260_rr). At least one adhesive layer (or adhesive member) may be placed between the first pad portion (260_rr) and the cushion bracket (230). Meanwhile, the first cushion structure (200) according to the embodiment of the present disclosure is not limited to the material, type, or shape of the pad portion (260).

[0085] The above pad portion (260) may include a first step portion (260_sd1) and a second step portion (260_sd2) formed lower than the periphery, taking into account the protruding steps (or the height step protruding from one surface of the cushion bracket (230)) of the bracket fixing portions (240a, 240b) arranged on the surface in the y-axis direction of the cushion bracket (230). The first step portion (260_sd1) and the second step portion (260_sd2) may be formed larger than the size of the bracket fixing portions (240a, 240b) (or the sliding holes (230_h1, 230_h2)). In addition, the first step portion (260_sd1) and the second step portion (260_sd2) may be arranged (or formed) at a position of the pad portion (260) that overlaps the position where the bracket fixing portions (240a, 240b) are arranged in the y-axis direction (or the position where the sliding holes (230_h1, 230_h2) are arranged).

[0086] Fig. 7 is a drawing showing an example of movement of a moving part according to operation of a driving device according to one embodiment. As an example, Fig. 7 separately illustrates only the configuration of a driving device arranged on one side of a main body (110) (e.g., the upper part of the main body (110_up) of Fig. 1) of a wearable electronic device according to an embodiment of the present disclosure.

[0087] Referring to FIGS. 1 to 7, a driving device (210) according to one embodiment may include a driving body (210_ba), a driving unit (210_di), a moving unit (210_ph), and a structure coupling unit (210_co), as in state 801. The description of the driving body (210_ba), the driving unit (210_di), the moving unit (210_ph), and the structure coupling unit (210_co) may be the same as or similar to the configuration of the driving body, the driving unit, the moving unit, and the structure coupling unit of the driving device (210) described above with reference to FIGS. 4 to 6.

[0088] According to one embodiment, the driving body (210_ba) may include a case (or housing, frame) forming an empty space therein. The driving body (210_ba) may include an upper portion in which a hole (210_ba_h) (or driving body hole) opened in the z-axis direction is formed, and a side portion (or rear portion) in which an opening (210_ba_op) opened in the y-axis direction is formed. The opening direction of the hole (210_ba_h) and the opening direction of the opening (210_ba_op) (or gate) may form different directions or angles (e.g., right angles). The front end of the driving body (210_ba) may include a closed shape. A structure coupling portion (210_co) may be arranged in the -z-axis direction of the driving body (210_ba) to be coupled with a structure arrangement area (110_at) formed in the upper portion (110_up) of the body. At least a part of the above structure coupling portion (210_co) may protrude in the -z-axis direction from the -z-axis direction lower surface of the driving body (210_ba). The structure coupling portion (210_co) may include various structures depending on the coupling method of the driving device (210). For example, when the driving device (210) is coupled to the structure placement area (110_at) in a hook coupling manner, the structure coupling portion (210_co) may include a hook structure. In addition, when the driving device (210) is coupled to the structure placement area (110_at) in a screw coupling manner, the structure coupling portion (210_co) may include at least one of a bolt or a nut used for screw coupling.

[0089] The above driving unit (210_di) may include, for example, a dial device. Alternatively, the driving unit (210_di) may include a rotating structure that can rotate in one direction or the other according to a user operation. In this regard, at least a portion of the driving unit (210_di) may protrude outward through a hole (210_ba_h) formed in the driving body (210_ba). Alternatively, at least a portion of the driving unit (210_di) may protrude in the z-axis direction from the upper surface of the driving body (210_ba) through the hole (210_ba_h). According to one embodiment, one side size of the driving unit (210_di) (e.g., the size of the diameter in the case of a cylindrical rotating structure) may be larger than one side size of the hole (210_ba_h) (e.g., the length of the hole (210_ba_h) in the x-axis direction). The other side size of the driving part (210_di) (e.g., in the case of a cylindrical rotating structure, the cylindrical thickness or height) may be formed to be smaller than or equal to the other side size of the hole (210_ba_h) (e.g., the length of the hole (210_ba_h) in the y-axis direction). A wrinkle or a certain pattern may be formed on one side of the driving part (210_di). As an example, the driving part (210_di) may rotate clockwise or counterclockwise around the y-axis (or -y-axis).

[0090] The above-described moving part (210_ph) is arranged at least partially inside the driving body (210_ba) and can move linearly in the y-axis direction in response to the operation of the driving part (210_di). In this regard, the moving part (210_ph) can be coupled to the driving part (210_di) in a certain manner. For example, the moving part (210_ph) can include a first gear pattern formed in the driving part (210_di) or a second gear pattern coupled with a shaft on which the first gear pattern is formed. The moving part (210_ph) can move in the -y-axis direction according to the first direction rotation (e.g., clockwise or counterclockwise rotation) of the driving part (210_di) and be arranged at a first ratio or more inside the driving body (210_ba) as in state 801. The moving part (210_ph) can move in the y-axis direction according to the second direction rotation (e.g., counterclockwise or clockwise rotation) of the driving part (210_di) and protrude in the y-axis direction from the driving body (210_ba) as in state 803. For example, the moving part (210_ph) can be arranged inside the driving body (210_ba) at a second ratio (e.g., a ratio smaller than the first ratio) or less. The size of the cross-section of the moving part (210_ph) in the y-axis direction can be formed to be similar to or smaller than the size of the opening (210_ba_op) formed in the rear part of the driving body (210_ba).

[0091] FIG. 8 is a drawing showing an example of a deformation of the first cushion structure shape according to one embodiment.

[0092] Referring to FIGS. 1 to 8, a first cushion structure (200) according to one embodiment may include a driving device (210) including at least a driving unit (210_di) and a moving unit (210_ph), and a bracket structure having at least a support bracket (220) and a cushion bracket (230). Additionally or alternatively, the first cushion structure (200) may further include at least some of a pad portion (260), bracket fixing portions (240a, 240b), and fastening portions (250a, 250b, 250c), as described above with reference to FIGS. 4 to 6.

[0093] According to one embodiment, the first cushion structure (200) can maintain the first state of the moving part (210_ph), as in state 901. For example, the driving device (210) can maintain a state in which the protrusion length of the moving part (210_ph) protruding from the driving body (210_ba) in the y-axis direction is the first length. Alternatively, state 901 may include a state in which the moving part (210_ph) does not protrude from the driving body (210_ba), a state in which the protrusion length is 0, or a state in which the protrusion length is less than a set reference value. State 901 may include, for example, a state in which the driving part (210_di) is rotated to the maximum in the first rotational direction (e.g., counterclockwise) or a state in which it is rotated a certain number of times. When the moving part (210_ph) is in a state where it protrudes less than a reference value in the y-axis direction, or when the moving part (210_ph) is arranged within the driving body (210_ba) at a specified ratio or more (e.g., 90% or more), the center of the cushion bracket (230) can form a curvature of a first size. Alternatively, the state 901 can include a state where the magnitude of the pressure applied by the moving part (210_ph) on the side of the cushion bracket (230) is less than a specified reference value (or a state where the magnitude of the pressure is 0). When there is no pressure applied by the moving part (210_ph), the center of the cushion bracket (230) can form a curvature of a first size according to a pre-design. In state 901, the edges of the cushion bracket (230) (e.g., the first edge (230_sd1) and the second edge (230_sd2), or the x-axis edge and the -x-axis edge) can remain coupled with the edges of the support bracket (220) (e.g., the first edge (220_sd1) and the second edge (220_sd2), or the x-axis edge and the -x-axis edge). According to one embodiment, in state 901, the edges (230_sd1, 230_sd2) of the cushion bracket (230) and the edges (220_sd1, 220_sd2) of the support bracket (220) can maintain the first alignment state.

[0094] According to one embodiment, the first cushion structure (200) may have the moving part (210_ph) changed to (or maintained) in the second state, such as in state 903. For example, the driving device (210) may have a state in which the protrusion length of the moving part (210_ph) protruding in the y-axis direction from the driving body (210_ba) (or one edge (y-axis edge) of the driving body (210_ba)) is a second length. The second length of the moving part (210_ph) may be greater than the first length. Alternatively, state 903 may include a state in which the moving part (210_ph) is maximally protruded from the driving body (210_ba) or a protruding state in which it is moved by a predetermined distance. Alternatively, state 901 may include, for example, a state in which the driving part (210_di) is maximally rotated in the second rotational direction (e.g., clockwise) or a predetermined number of times. According to various embodiments, the protrusion length of the moving part (210_ph) protruding from one edge (e.g., the opening (210_ba_op)) of the driving body (210_ba) may vary depending on the number of rotations (or rotation angle, rotation degree) of the driving part (210_di). When the moving part (210_ph) protrudes more than a reference value in the y-axis direction, or when the moving part (210_ph) is arranged within the driving body (210_ba) at a ratio less than a specified ratio (e.g., less than 50%), the center of the cushion bracket (230) may form a curvature of a second magnitude. The curvature of the second magnitude may include a value smaller than the curvature of the first magnitude. Alternatively, the curvature of the second magnitude may include a value that forms a gentler state (or a flat state) than the state in which the center of the cushion bracket (230) forms the curvature of the first magnitude. The second size of curvature formed at the center of the cushion bracket (230) may vary depending on the degree of rotation of the driving unit (210_di). For example, as the degree of rotation of the driving unit (210_di) increases (or increases), the second size of curvature may become smaller (or the center of the cushion bracket (230) may become more gentle).

[0095] As an example, state 903 may include a state in which the magnitude of the pressure applied by the moving part (210_ph) is greater than or equal to a specified reference value (or a state in which the magnitude of the pressure is maximum) in terms of the cushion bracket (230). When the pressure applied by the moving part (210_ph) is maximum, the center of the cushion bracket (230) may form a curvature of a second magnitude according to a pre-design. In state 903, the edges (230_sd1, 230_sd2) of the cushion bracket (230) may remain coupled with the edges (220_sd1, 220_sd2) of the support bracket (220). According to one embodiment, in state 903, the edges (230_sd1, 230_sd2) of the cushion bracket (230) and the edges (220_sd1, 220_sd2) of the support bracket (220) can maintain a second alignment state different from the first alignment state. The alignment state of the edges (230_sd1, 230_sd2) of the cushion bracket (230) and the edges (220_sd1, 220_sd2) of the support bracket (220) can vary depending on the degree of rotation of the driving unit (210_di).

[0096] Figure 9 is a drawing showing an example of a bracket fixing part shape according to one embodiment.

[0097] Referring to FIGS. 1 to 9, the bracket fixing parts (240a, 240b) according to one embodiment include a first bracket fixing part (240a) used to fix a first edge of a cushion bracket (230) (e.g., a first edge (230_sd1) of the cushion bracket (230) based on the drawing shown in FIG. 8) to a first edge of a support bracket (220) (e.g., a first edge (220_sd1) of the support bracket (220) based on the drawing shown in FIG. 8)) and a second bracket fixing part (240b) used to fix a second edge of a cushion bracket (230) (e.g., a second edge (230_sd2) of the cushion bracket (230) based on the drawing shown in FIG. 8)) to a second edge of a support bracket (220) (e.g., a second edge (220_sd2) of the support bracket (220) based on the drawing shown in FIG. 8)). A bracket fixing part (240b) may be included. The first bracket fixing part (240a) and the second bracket fixing part (240b) may have the same shape and the same size. According to one embodiment, the first bracket fixing part (240a) and the second bracket fixing part (240b) may have different directions of arrangement during the joining process. For example, the first bracket fixing part (240a) and the second bracket fixing part (240b) may be arranged symmetrically left and right with respect to the center of the cushion bracket (230).

[0098] The above bracket fixing parts (240a, 240b) may include, for example, a fixing part body (240_ba), a fixing part body front (240_fr), a fixing part body rear (240_rr), and a coupling protrusion (240_pr).

[0099] At least a portion of the fixed part body (240_ba) may include a curved surface corresponding to the inner curved curvature of the cushion bracket (230) in response to being coupled to the inner curved edge of the cushion bracket (230). The fixed part body (240_ba) may have a certain thickness and may have a polygonal shape or an oval shape. However, the present disclosure is not limited to the shape of the fixed part body (240_ba), and at least a portion of the fixed part body (240_ba) may include various shapes smaller than the sizes of the sliding holes (230_h1, 230_h2) formed in the cushion bracket (230). The fixed part body (240_ba) may be coupled to correspond to the shapes of some of the sliding holes (230_h1, 230_h2) of the cushion bracket (230) (e.g., obliquely or with a certain inclination).

[0100] The front surface (240_fr) of the fixed body includes the front portion of the fixed body (240_ba), and may include a surface that is observed parallel to the inner surface of the cushion bracket (230) while the bracket fixing parts (240a, 240b) are coupled to the cushion bracket (230). A hole (240_h) of a coupling protrusion (240_pr) may be formed at the center of the front surface (240_fr) of the fixed body. The hole (240_h) may include an inclined entrance portion corresponding to the inclined shape of the front surface (240_fr) of the fixed body. The front surface (240_fr) of the fixed body may be formed as a curved surface having the same curvature as the rear surface (240_rr) of the fixed body. However, the present invention is not limited thereto, and the front surface (240_fr) of the fixed body may include a different curvature or flat surface than the rear surface (240_rr) of the fixed body.

[0101] The rear surface (240_rr) of the fixed body is the rear surface of the fixed body (240_ba), and may include a surface that is not observed from the outside as it is a surface that comes into contact with the inner surface of the cushion bracket (230) while being coupled to the cushion bracket (230). At least a portion of the rear surface (240_rr) of the fixed body (e.g., the rear surface that comes into contact with at least a portion of the inner surface of the first cushion structure (200)) may include a curved surface. As an example, the curvature of the curved surface of the rear surface (240_rr) of the fixed body may correspond to the curvature of the inner edge of the cushion bracket (230).

[0102] The above-mentioned coupling protrusion (240_pr) includes a hole (240_h) penetrating from the front surface (240_fr) of the fixing body toward the rear surface (240_rr) of the fixing body, and may protrude from the surface of the rear surface (240_rr) of the fixing body by a certain length in the rear direction. Fastening parts (e.g., a first fastening part (250a) and a second fastening part (250b)) may be inserted into the internal hole (240_h) of the coupling protrusion (240_pr). The length of the coupling protrusion (240_pr) (or the length of the hole (240_h) included in the coupling protrusion (240_pr)) may be shorter than the lengths of the first fastening part (250a) and the second fastening part (250b). Alternatively, the lengths of the first fastening part (250a) and the second fastening part (250b) may be longer than the length of the coupling protrusion (240_pr). One end of the above-described coupling protrusion (240_pr) (e.g., the end toward the front surface (240_fr) of the fixing body, or the beginning of the hole (240_h) of the coupling protrusion (240_pr), or the entrance portion into which the first coupling portion (250a) or the second coupling portion (250b) is inserted) may be formed to have a shape similar to the front surface (240_fr) of the fixing body. For example, one end of the coupling protrusion (240_pr) may have an inclined shape. The other end of the coupling protrusion (240_pr) (e.g., the end toward the rear surface (240_rr) of the fixing body, or the end of the hole (240_h) of the coupling protrusion (240_pr), or the exit portion into which the first coupling portion (250a) or the second coupling portion (250b) is protruded after being inserted) may be formed to be flat. Alternatively, the other end of the coupling protrusion (240_pr) may have a shape corresponding to the end shape of the bracket connecting portions (bracket connecting portions (220_bos1, 220_bos2) of FIG. 5 or FIG. 6) formed on the support bracket (220).

[0103] Fig. 10 is a drawing showing an example of a coupling relationship between a bracket fixing portion and a support bracket according to one embodiment. As an example, Fig. 10 is a drawing showing a first edge (e.g., x-axis edge) of a support bracket (220), a first edge of a cushion bracket (230), a first bracket fixing portion (240a), and a first fastening portion (250a).

[0104] Referring to FIGS. 1 to 10, according to one embodiment, at least a portion of the first edge (220_sd1) of the support bracket (220) and the first edge (230_sd1) of the cushion bracket (230) may be aligned front to back with respect to the y-axis. For example, with respect to the y-axis direction (or -y-axis direction), at least a portion of the first bracket connecting portion (220_bos1) formed in the support bracket (220) may overlap with the first sliding hole (230_h1) formed in the cushion bracket (230). For example, the size of the end cross-section observed in the y-axis direction of the first bracket connecting portion (220_bos1) may be equal to or smaller than the size of the first sliding hole (230_h1). Alternatively, the shape and size of the y-axis direction end section of the first bracket connecting portion (220_bos1) may be identical to or similar to the shape and size of the -y-axis direction end section of the coupling protrusion (240_pr) of the first bracket fixing portion (240a). Alternatively, the first bracket connecting portion (220_bos1) may be formed to protrude in the y-axis direction from the y-axis direction surface (or inner surface, bottom surface) of the support bracket (220), and may include a recessed groove in the -y-axis direction or a hole formed in the -y-axis direction. The shape and size of the groove (or hole) formed in the y-axis direction end section of the first bracket connecting portion (220_bos1) may be identical to or similar to the shape and size of the outlet of the hole formed in the -y-axis direction end section of the coupling protrusion (240_pr) of the first bracket fixing portion (240a). The y-axis end section of the first bracket connecting portion (220_bos1) may be formed horizontally on the xz plane. The end section of one side of the coupling protrusion (240_pr) of the first bracket fixing portion (240a) inserted into the first sliding hole (230_h1) facing the first bracket connecting portion (220_bos1) may be formed horizontally on the xz plane.

[0105] According to one embodiment, the engaging protrusion (240_pr) of the first bracket fixing portion (240a) may be positioned to protrude further in the -y-axis direction from one surface (e.g., a surface in the -y-axis direction) of the cushion bracket (230) by penetrating the first sliding hole (230_h1) formed in the cushion bracket (230). In response to the pressing or releasing of the moving portion (210_ph), the peripheral portion (e.g., a border, an outer surface) of the engaging protrusion (240_pr) may slide along the first sliding hole (230_h1). Alternatively, depending on the observation criterion, the first edge (230_sd1) of the cushion bracket (230) may slide (or deform) in the x-axis direction or the -x-axis direction with respect to the engaging protrusion (240_pr). The support bracket (220) can support the cushion bracket (230) while the first edge (230_sd1) of the cushion bracket (230) slides (or while it is stretched in the x-axis direction, or while the arrangement shape of the first edge (230_sd1) is changed, or while it is deformed).

[0106] The alignment state of the first edge (220_sd1) of the support bracket (220) and the first edge (230_sd1) of the cushion bracket (230) described above and the coupling state of the first bracket fixing portion (240a) and the first fastening portion (250a) can be applied identically or similarly to the second edge (220_sd2) of the support bracket (220) (e.g., the -x-axis edge of the support bracket (220) illustrated in FIG. 8) and the second edge (230_sd2) of the cushion bracket (230) (e.g., the -x-axis edge of the cushion bracket (230) illustrated in FIG. 8), the second bracket fixing portion (e.g., the second bracket fixing portion (240b) illustrated in FIG. 6) and the second fastening portion (e.g., the second fastening portion (250b) illustrated in FIG. 6). As an example, the second edge (230_sd2) of the cushion bracket (230) can be changed in its arrangement state by the pressing or releasing of the moving part (210_ph) while being supported by the second edge (220_sd2) of the support bracket (220).

[0107] FIG. 11 is a drawing showing an example of movement of a bracket fixing part according to one embodiment. The first cushion structure (200) shown in FIG. 11 shows an example in which the pad portion (260) (e.g., the pad portion (260) of FIG. 4) is removed, compared to the first cushion structure described above (e.g., the first cushion structure shown in FIGS. 4 to 6). Additionally, the first cushion structure (200) may include a driving device (210), and FIG. 11 is a drawing showing an example in which the driving device (210) is covered by the cushion bracket (230) when observed from the direction of the cushion bracket (230).

[0108] Referring to FIGS. 1 to 11, the first cushion structure (200) may include at least a driving device (e.g., a driving device (210) of FIG. 4), a support bracket (220), a cushion bracket (230), a first bracket fixing portion (240a), and a second bracket fixing portion (240b). Additionally or alternatively, the driving device (210) may further include a first fastening portion (250a) that penetrates the first bracket fixing portion (240a) and is coupled to one side of the support bracket (220) (e.g., the first bracket connecting portion (220_bos1) of FIG. 5), and a second fastening portion (250b) that penetrates the second bracket fixing portion (240b) and is coupled to the other side of the support bracket (220) (e.g., the second bracket connecting portion (220_bos2) of FIG. 5). The above cushion bracket (230) can have at least a part of its arrangement form or arrangement shape changed by the movement of the moving part (e.g., the moving part (210_ph) of FIG. 7) included in the driving device (210).

[0109] According to one embodiment, the first cushion structure (200) may include a state in which the center (or centre) of the cushion bracket (230) forms a curved surface of the first curvature, as in state 1101. In this regard, the moving part (210_ph) of the driving device (210) may be in a state in which it does not protrude in the y-axis direction, or in a state in which the protrusion amount of the moving part (210_ph) in the y-axis direction is less than a set (or determined) reference value. In a state in which the protrusion amount of the moving part (210_ph) is less than the reference value, the center of the cushion bracket (230) may have a state in which it is concavely bent in the -y-axis direction. Alternatively, in state 1101, the cushion bracket (230) may have a state in which it maintains a curved surface created during the manufacturing process. When the cushion bracket (230) maintains the surface of the first curvature, the first bracket fixing portion (240a) may be positioned at one edge of the first sliding hole (230_h1) (e.g., the x-axis edge of the first sliding hole (230_h1)), and the second bracket fixing portion (240b) may be positioned at one edge of the second sliding hole (e.g., the -x-axis edge of the second sliding hole (e.g., the second sliding hole (230_h2) of FIG. 5)).

[0110] When the moving part (210_ph) of the driving device (210) moves in the y-axis direction (or when the y-axis direction movement amount or the y-axis direction protrusion amount of the moving part (210_ph) is equal to or greater than a set (or determined) reference value), the cushion bracket (230) may be deformed so that its center is flatter than in the 1101 state, as in the 1103 state. Alternatively, when the y-axis direction protrusion amount of the moving part (210_ph) is equal to or greater than the reference value, the center of the cushion bracket (230) may form a curved surface of a second curvature that is smaller than the curved surface of the first curvature of the 1101 state (or a curved surface that is gentler than the curved surface of the center of the 1101 state). According to one embodiment, as the moving part (210_ph) presses the center of the cushion bracket (230) in the y-axis direction, the center of the cushion bracket (230) may protrude in the y-axis. As the center of the cushion bracket (230) protrudes in the y-axis, the edges on both sides of the cushion bracket (230) (e.g., the first edge (230_sd1) and the second edge (230_sd2) of the cushion bracket (230)) can each be deformed in a direction away from the center. As an example, when the cushion bracket (230) is deformed into a surface of the second curvature (or a surface that is flatter than the 1101 state), the first bracket fixing portion (240a) may be moved from one edge of the first sliding hole (230_h1) (e.g., the x-axis edge of the first sliding hole (230_h1)) to the other edge (e.g., the -x-axis edge of the first sliding hole (230_h1)), and the second bracket fixing portion (240b) may be moved from one edge of the second sliding hole (e.g., the second sliding hole (230_h2) of FIG. 5)) (e.g., the -x-axis edge of the second sliding hole (230_h2) of FIG. 5)) to the other edge (e.g., the x-axis edge of the second sliding hole (230_h2)).

[0111] Fig. 12 is a drawing showing the coupling relationship between a cushion bracket and a moving part according to one embodiment with respect to the first direction. Fig. 13 is a drawing showing the coupling relationship between a cushion bracket and a moving part according to one embodiment with respect to the second direction. Here, the first cushion structure (200) shown in Fig. 12 is a drawing showing an example of a form in which the pad part is removed from the first cushion structure described above with reference to Figs. 4 to 6. The cushion bracket (230) and the moving part (210_ph) shown in Fig. 13 may be an example of the cushion bracket and the moving part described above with reference to Figs. 2 to 11.

[0112] Referring to FIGS. 1 to 11 and FIGS. 12 and 13, a first cushion structure (200) according to an embodiment may include a cushion bracket (230), a support bracket (220), a driving device (210), a first bracket fixing part (240a), a second bracket fixing part (240b), a first fastening part (250a), a second fastening part (250b), and a third fastening part (250c). The driving device (210) may include a driving body (e.g., the driving body (210_ba) of FIG. 4), a driving part (e.g., the driving part (210_di) of FIG. 4), and a moving part (210_ph), as described above with reference to FIGS. 4 to 7. The above moving part (210_ph) may include a moving body (210_ph_ba) that is connected to a driving part (210_di) arranged on a driving body (210_ba), a first protrusion (210_pr1), a second protrusion (210_pr2) that protrudes in the y-axis direction from the moving body (210_ph_ba), and a bracket coupling part (210_ph_co).

[0113] According to one embodiment, the cushion bracket (230) may include a center portion that is concavely formed in the -y-axis direction when observed from the y-axis in the -y-axis direction as described above, and a first edge (230_sd1) and a second edge (230_sd2) that extend in a direction away from the center portion, for example, in the direction of both sides (e.g., the x-axis and -x-axis sides). A first sliding hole (230_h1) is arranged in the first edge (230_sd1) (e.g., the edge in the x-axis direction), and at least a portion of the first edge (230_sd1) of the cushion bracket (230) may overlap with the first edge of the support bracket (220) (e.g., the first edge (220_sd1) of the support bracket (220) illustrated in FIG. 8) with respect to the y-axis direction. As an example, at least a part of the first bracket fixing portion (240a) can be inserted into the first sliding hole (230_h1). The first bracket fixing portion (240a) can be coupled to the first bracket connecting portion (220_bos1) of the support bracket (220) through the first sliding hole (230_h1) and the first fastening portion (250a). The first sliding hole (230_h1) can include a hole shape in which the length in the x-axis direction is longer than the length in the y-axis or z-axis direction.

[0114] A second sliding hole (e.g., the second sliding hole (230_h2) of FIG. 4) is arranged in the second edge (230_sd2) (e.g., the edge in the -x-axis direction), and at least a portion of the second edge (230_sd2) of the cushion bracket (230) may overlap with a second edge of the support bracket (220) (e.g., the second edge (220_sd2) of the support bracket (220) illustrated in FIG. 8) with respect to the y-axis direction. As an example, at least a portion of the second bracket fixing portion (240b) may be inserted into the second sliding hole (230_h2). The second bracket fixing portion (240b) can be coupled to the second bracket connecting portion (e.g., the second bracket connecting portion (220_bos2) of FIG. 6) of the support bracket (220) through the second sliding hole (230_h2) and the second fastening portion (250b). The second sliding hole (230_h2) may include a hole shape in which the length in the -x-axis direction (or the -x-axis direction) is longer than the length in the y-axis or z-axis direction. According to one embodiment, the second sliding hole (230_h2) may have a size that is the same as or similar to that of the first sliding hole (230_h1). The second sliding hole (230_h2) may be arranged at a position symmetrical to the first sliding hole (230_h1) with respect to the center of the cushion bracket (230).

[0115] The above cushion bracket (230) may include a bracket fixing hole (230_hc). The bracket fixing hole (230_hc) may be formed to penetrate from a point (e.g., center) of the cushion bracket (230) in the front-back direction (e.g., from the y-axis to the -y-axis direction). The size of the bracket fixing hole (230_hc) may be, for example, the same as or similar to a portion of the third fastening portion (250c). The bracket fixing hole (230_hc) may be aligned with a portion of the moving portion (210_ph). Accordingly, the third fastening portion (250c) may pass through the bracket fixing hole (230_hc) and then be fastened to a portion of the moving portion (210_ph). In this regard, the moving part (210_ph) may include a bracket coupling part (210_ph_co) into which at least a part of the third fastening part (250c) can be inserted or coupled. Alternatively, the third fastening part (250c) may fix at least a portion including a point (e.g., a center) of the cushion bracket (230) to a portion of the moving part (210_ph). When the center portion (or at least a portion including the center) of the cushion bracket (230) is fixed to the moving part (210_ph) by the third fastening part (250c), the degree of protrusion (or degree of bending, or curvature) of the center of the cushion bracket (230) may vary depending on the movement of the moving part (210_ph). For example, while the moving part (210_ph) moves in the y-axis direction, the curvature of the center (or at least a portion including the center point) of the cushion bracket (230) may decrease and be gently deformed. While the moving part (210_ph) moves in the -y-axis direction, the curvature of the center of the cushion bracket (230) may increase and be deformed to increase the degree of bending.

[0116] The above cushion bracket (230) may include a first mounting portion (230_r1), a second mounting portion (230_r2), and a bracket hole support portion (230_hc_sp) arranged on one surface (e.g., a surface facing the -y-axis direction) of the second bracket body (230_ba). The first mounting portion (230_r1) may be arranged to be offset in the x-axis direction based on an area where the center between the x-axis and the -x-axis of the second bracket body (230_ba) intersects the center between the z-axis and the -z-axis.

[0117] The first mounting portion (230_r1) has a groove formed therein and can protrude in the -y-axis direction from one surface of the second bracket body (230_ba). As an example, the first mounting portion (230_r1) can be arranged on the second bracket body (230_ba) symmetrically with respect to the second mounting portion (230_r2) with respect to the bracket hole support portion (230_hc_sp). The size of the groove of the first mounting portion (230_r1) can have a size corresponding to the size of one end of the first protrusion (210_pr1) arranged on the moving portion (210_ph).

[0118] The second mounting portion (230_r2) may be arranged to be offset in the -x-axis direction based on an area where the center between the x-axis and the -x-axis of the second bracket body (230_ba) intersects the center between the z-axis and the -z-axis. Alternatively, the second mounting portion (230_r2) may be arranged on the second bracket body (230_ba) symmetrically to the first mounting portion (230_r1) based on the bracket hole support portion (230_hc_sp). The size of the groove of the second mounting portion (230_r2) may have a size corresponding to the size of one end of the second protrusion (210_pr2) arranged on the moving portion (210_ph). Alternatively, the size and shape of the groove of the second mounting portion (230_r2) may be identical or similar to the size and shape of the groove of the first mounting portion (230_r1).

[0119] The bracket hole support (230_hc_sp) may be positioned between the first mounting portion (230_r1) and the second mounting portion (230_r2). Alternatively, the bracket hole support (230_hc_sp) may be connected to the bracket fixing hole (230_hc). In this regard, the bracket hole support (230_hc_sp) may have a hole formed on the inside thereof that penetrates forward and backward (e.g., y-axis and -y-axis). The hole formed on the inside of the bracket hole support (230_hc_sp) may be connected to the bracket fixing hole (230_hc). A cross-section of one end (e.g., an end in the -y-axis direction) of the bracket hole support (230_hc_sp) may be formed parallel to the xz plane. The above bracket hole support member (230_hc_sp) may be aligned with the bracket coupling member (210_ph_co) formed on the moving member (210_ph). Alternatively, one end (e.g., the end in the -y-axis direction) of the bracket hole support member (230_hc_sp) may be in contact with one end (e.g., the end in the y-axis direction) of the bracket coupling member (210_ph_co) formed on the moving member (210_ph).

[0120] The above moving part (210_ph) may include a moving body (210_ph_ba) located inside the driving device (210) and coupled with the driving part (210_di), a first protrusion (210_pr1) protruding from the moving body (210_ph_ba) in the y-axis direction and mounted on a first mounting part (230_r1), a second protrusion (210_pr2) protruding from the moving body (210_ph_ba) in the y-axis direction and mounted on a second mounting part (230_r2), and a bracket coupling part (210_ph_co) protruding from the moving body (210_ph_ba) in the y-axis direction and contacting one side of a bracket hole support part (230_hc_sp).

[0121] At least a part of the above-described moving body (210_ph_ba) is disposed inside the driving body (210_ba) and can move linearly in the y-axis direction or the -y-axis direction in response to the movement of the driving unit (210_di). The moving body (210_ph_ba) is exemplified as having a length in the x-axis direction longer than a length in the y-axis or z-axis direction, but the present disclosure is not limited thereto. For example, the moving body (210_ph_ba) may be provided in various shapes, such as a rod shape or a polygonal pillar shape. One edge (e.g., the -y-axis edge) of the moving body (210_ph_ba) may be coupled to the driving unit (210_di). As an example, one edge of the moving body (210_ph_ba) may be fastened to the driving unit (210_di) so as to move linearly in the y-axis direction in response to the operation of the driving unit (210_di). For example, the driving unit (210_di) may include a structure having a gear pattern formed thereon (e.g., a shaft having a gear pattern formed thereon), and the moving body (210_ph_ba) may include a groove into which at least a portion of the first gear pattern structure may be inserted. A second gear pattern that engages with the first gear pattern structure of the driving unit (210_di) may be arranged inside the groove formed in the moving body (210_ph_ba). In response to an operation (e.g., rotation) of the driving unit (210_di), the moving body (210_ph_ba) including the second gear pattern may move linearly in the y-axis or -y-axis direction.

[0122] The first protrusion (210_pr1) may be arranged to be offset in a first direction (e.g., x-axis direction) based on the center of the x-axis and -x-axis of the movable body (210_ph_ba). Alternatively, the first protrusion (210_pr1) may protrude from one edge (e.g., x-axis edge) of the movable body (210_ph_ba) in the y-axis direction by a certain length, and at least a portion of the first protrusion (210_pr1) may be placed (or inserted) into the first mounting portion (230_r1) formed in the cushion bracket (230). At least a portion of the first protrusion (210_pr1) may be inserted into the first mounting portion (230_r1), and the cushion bracket (230) on which the first mounting portion (230_r1) is formed may be pressed in the y-axis direction in response to the movement of the movable body (210_ph_ba). In this regard, the size of one end (e.g., the y-axis end) of the first protrusion (210_pr1) may be formed to be the same as or similar to the size of the groove formed in the first mounting portion (230_r1). Alternatively, the size of the groove formed in the first mounting portion (230_r1) may be formed to be larger than one end of the first protrusion (210_pr1) so as to facilitate insertion of the first protrusion (210_pr1) into the first mounting portion (230_r1).

[0123] The second protrusion (210_pr2) may be arranged to be offset in a second direction (e.g., -x-axis direction) based on the center of the x-axis and -x-axis of the movable body (210_ph_ba). Alternatively, the second protrusion (210_pr2) may protrude from one edge (e.g., -x-axis edge) of the movable body (210_ph_ba) in the y-axis direction by a certain length, and at least a portion of the second protrusion (210_pr2) may be placed (or inserted) into the second mounting portion (230_r2) formed in the cushion bracket (230). At least a portion of the second protrusion (210_pr2) may be inserted into the second mounting portion (230_r2), and the cushion bracket (230) on which the second mounting portion (230_r2) is formed may be pressed in the y-axis direction in response to the movement of the movable body (210_ph_ba). The shape of one end of the second protrusion (210_pr2) may be formed to be identical or similar to the shape of one end of the first protrusion (210_pr1). For example, the size of one end (e.g., the y-axis end) of the second protrusion (210_pr2) may be formed to be identical or similar to the size of the groove formed in the second mounting portion (230_r2). Alternatively, the size of the groove formed in the second mounting portion (230_r2) may be formed to be larger than the one end of the second protrusion (210_pr2) so as to facilitate insertion of the second protrusion (210_pr2) into the second mounting portion (230_r2).

[0124] The bracket coupling portion (210_ph_co) may be positioned between the first protrusion (210_pr1) and the second protrusion (210_pr2). The bracket coupling portion (210_ph_co) may include a recessed groove in the -y-axis direction. The bracket coupling portion (210_ph_co) may be aligned with the bracket hole support portion (230_hc_sp) of the cushion bracket (230). Alternatively, a hole formed in the center of the bracket coupling portion (210_ph_co) (or a hole formed in the -y-axis direction from the y-axis) may be aligned with a hole formed in the center of the bracket hole support portion (230_hc_sp). The third fastening portion (250c) can fix the bracket fixing hole (230_hc), the bracket hole support portion (230_hc_sp), and the bracket coupling portion (210_ph_co) by penetrating through the bracket fixing hole (230_hc), the bracket hole support portion (230_hc_sp), and the bracket coupling portion (210_ph_co). The bracket coupling portion (210_ph_co) can be used to pressurize a portion (e.g., the center) of the cushion bracket (230), for example, a portion where the bracket fixing hole (230_hc) is formed (or at least a portion of the cushion bracket (230) including the bracket fixing hole (230_hc)) in the y-axis direction or pull it in the -y-axis direction. When the above moving part (210_ph) is formed as an integral body, the moving body (210_ph_ba), the first protrusion (210_pr1), the second protrusion (210_pr2), and the bracket coupling part (210_ph_co) may be formed of the same material, but the present disclosure is not limited thereto.

[0125] Meanwhile, in the above description, it is exemplified that two protrusions are formed on the moving part (210_ph) and correspondingly, two mounting parts are formed on the cushion bracket (230), but the present disclosure is not limited thereto. For example, the moving part (210_ph) may have more than two mounting parts formed at a predetermined interval in the y-axis direction, and the cushion bracket (230) may include mounting parts aligned with the more than two mounting parts. In addition, the moving part (210_ph) may have more than two bracket coupling parts formed, and the cushion bracket (230) may include more than two bracket hole support parts and bracket fixing holes aligned with the more than two bracket coupling parts. Alternatively, the driving device (210) may include only the protrusions of the moving part (210_ph) and the mounting parts of the cushion bracket (230), and the bracket fixing hole (230_hc), the bracket hole support part (230_hc_sp), and the bracket coupling part (210_ph_co) may be omitted from the driving device (210) configuration. Alternatively, the driving device (210) may include only the bracket fixing hole (230_hc), the bracket hole support part (230_hc_sp), and the bracket coupling part (210_ph_co), and the protrusions of the moving part (210_ph) and the mounting parts of the cushion bracket (230) may be omitted from the driving device (210) configuration. According to various embodiments, the cushion bracket (230) may include a bracket fixing hole penetrating the front and rear surfaces of the cushion bracket (230) in which the mounting part is formed. For example, the fastening member can be fastened to the protrusions of the moving member through a bracket fixing hole formed in the mounting area.

[0126] Fig. 14 illustrates an example of a partial configuration of a first type cushion structure according to one embodiment. In Fig. 14, only a partial configuration of the first cushion structure illustrated in Figs. 1 to 6 is illustrated as an example. Accordingly, the first type cushion structure (200_1) illustrated in Fig. 14 may additionally or alternatively further include a support bracket (220), a pad portion (260), bracket fixing portions (240a, 240b), and fastening portions (250a, 250b, 250c) described in the previous drawings.

[0127] Referring to FIGS. 1 to 14, according to one embodiment, a first type cushion structure (200_1) may include a first type driving device (210_t1) and a first type cushion bracket (230_ch1) (or a first modified cushion bracket). The main body to which the first type cushion structure (200_1) is applied may have some different configurations from the main body (110) described in FIG. 1 or 4. According to one embodiment, the main body of a wearable electronic device to which the first type cushion structure (200_1) is applied may include a modified structure arrangement area in which the first type driving device (210_t1) can be mounted. For example, the modified structure arrangement area of ​​the main body may include an area in which two coupling structures are arranged so that a first driving device part (210_1) and a second driving device part (210_2) included in the first type driving device (210_t1) can be coupled, respectively.

[0128] The above first type driving device (210_t1) may include a first driving device portion (210_1) and a second driving device portion (210_2).

[0129] The first driving device part (210_1) may include a first driving body (210_ba_1), a first driving unit (210_di_1), a first structure coupling unit (210_co_1), and a first moving unit (210_ph1).

[0130] The above first driving body (210_ba_1) may have the same or similar structure as the driving body (210_ba) of the driving device (210) described in the preceding drawings, except that one side thereof is connected to the second driving body (210_ba_2). For example, the first driving body (210_ba_1) may include a first driving body hole (210_ba_h1) provided by removing a portion of the upper portion of the body so that at least a portion of the first driving part (210_di_1) protrudes upward (e.g., in the z-axis direction) more than the surface of the upper portion of the body, and may include a first moving part opening (e.g., a first opening corresponding to the opening (210_ba_op) of FIG. 7) for linear movement of the first moving part (210_ph1) in the y-axis direction.

[0131] The first structure coupling portion (210_co_1) may be inserted into a structure arrangement area formed in the main body (e.g., a modified form of the structure arrangement area (110_at) of FIG. 4). As an example, the first structure coupling portion (210_co_1) may couple the first drive unit portion (210_1) to the main body in at least one of various ways, such as a hook coupling method or a screw coupling method.

[0132] The first driving unit (210_di_1) can perform a movement in one direction in response to a user operation and transmit the force generated according to the movement to the first moving unit (210_ph1). As an example, the first driving unit (210_di_1) can have a structure substantially the same as or similar to the driving unit (210_di) described above in FIGS. 4 to 6. For example, the first driving unit (210_di_1) can rotate clockwise or counterclockwise according to a user operation and transmit the force according to the rotational movement to the first moving unit (210_ph1). In this regard, at least a portion of the first driving unit (210_di_1) can protrude (or be exposed) through a first driving unit hole (210_ba_h1) formed at the top of the first driving body (210_ba_1).

[0133] The first moving part (210_ph1) may have a structure in which it is positioned inside the first driving body (210_ba_1) or moves in the y-axis direction from the first driving body (210_ba_1) in response to the operation of the first driving part (210_di_1), or a portion protruding outward from the first driving body (210_ba_1) may move into the inside of the first driving body (210_ba_1). As an example, the first moving part (210_ph1) may have a structure similar to the moving part (210_ph) described above in FIG. 13. According to one embodiment, the first moving part (210_ph1) may include a part that is coupled to the first driving part (210_di_1) and a part that is mounted (or inserted, coupled) to the first mounting part (230_r1) formed on one side (e.g., the side in the -y-axis direction) of the first type cushion bracket (230_ch1). The first moving part (210_ph1) converts the rotational motion of the first driving part (210_di_1) into a linear motion, and may move in the y-axis or -y-axis direction according to the linear motion. The shape of one end (e.g., the y-axis edge) of the first moving part (210_ph1) may have a structure that can be inserted into and mounted on the first mounting part (230_r1). In this regard, the first moving part (210_ph1) may include a pillar that protrudes in the y-axis direction. According to various embodiments, one end of the first moving part (210_ph1) inserted into the first mounting part (230_r1) may be fixed to the first mounting part (230_r1) by a fastening part (e.g., a bolt, an adhesive member).

[0134] The second driving device part (210_2) may include a second driving body (210_ba_2), a second driving unit (210_di_2), a second structure coupling unit (210_co_2), and a second moving unit (210_ph2).

[0135] The second driving body (210_ba_2) may have a structure identical to or similar to the driving body (210_ba) of the driving device (210) described in the preceding drawings, except that at least a portion thereof is connected to the first driving body (210_ba_1). For example, the second driving body (210_ba_2) may include a case forming an empty space therein, a second driving part hole (210_ba_h2) formed by removing at least a portion of an upper portion of the case, and a second opening formed in the y-axis direction of the case and used as a movement passage of the second moving part (210_ph2).

[0136] The second structure coupling part (210_co_2) may be formed at the lower end of the second driving body (210_ba_2) and may be arranged parallel to the first structure coupling part (210_co_1). The second structure coupling part (210_co_2) may be inserted into the structure arrangement area of ​​the body part. The second structure coupling part (210_co_2) may fix the second driving body (210_ba_2) to the body part by hook coupling or screw coupling with respect to the structure arrangement area.

[0137] The second driving unit (210_di_2) may have a structure substantially identical or similar to that of the first driving unit (210_di_1). As an example, the second driving unit (210_di_2) may be provided in a cylindrical shape so as to be rotatable, may have a pattern (or wrinkles) formed on at least a portion thereof for user manipulation, and may be arranged so that at least a portion thereof protrudes toward the top of the second driving unit (210_ba_2) through the second driving unit hole (210_ba_h2) of the second driving unit body (210_ba_2). The second driving unit (210_di_2) may rotate clockwise or counterclockwise depending on user manipulation, and may operate independently of the first driving unit (210_di_1).

[0138] The second moving part (210_ph2) may have a structure in which it is positioned inside the second driving body (210_ba_2) or moves in the y-axis direction from the second driving body (210_ba_2) in response to the operation of the second driving part (210_di_2), or a portion protruding outward from the second driving body (210_ba_2) may move into the inside of the second driving body (210_ba_2). According to one embodiment, the second moving part (210_ph2) may include a portion that is coupled to the second driving part (210_di_2) and a portion that is mounted (or inserted, coupled) to a second mounting part (230_r2) formed on one surface (e.g., a surface in the -y-axis direction) of the first type cushion bracket (230_ch1). The second moving part (210_ph2) converts the rotational motion of the second driving part (210_di_2) into linear motion, and can move in the y-axis or -y-axis direction according to the linear motion. The shape of one end (e.g., y-axis edge) of the second moving part (210_ph2) may have a structure that can be inserted and placed in the second mounting part (230_r2). In this regard, the second moving part (210_ph2) may include a pillar protruding in the y-axis direction. According to various embodiments, one end of the second moving part (210_ph2) inserted into the second mounting part (230_r2) may be fixed to the second mounting part (230_r2) by a fastening part (e.g., bolt, adhesive member). The second moving part (210_ph2) can move independently of the linear motion of the first moving part (210_ph1).

[0139] Meanwhile, in the illustrated drawing, the first moving part (210_ph1) and the second moving part (210_ph2) each include one pillar part inserted into the first mounting part (230_r1) and the second mounting part (230_r2), respectively. However, the embodiments of the present disclosure are not limited thereto. For example, the first moving part (210_ph1) and the second moving part (210_ph2) may each include a plurality of pillars. Accordingly, the first type cushion bracket (230_ch1) may include a plurality of mounting parts corresponding to the plurality of pillar parts of each of the moving parts. For example, if the first moving part (210_ph1) and the second moving part (210_ph2) each include three pillar parts, the first type cushion bracket (230_ch1) may include three support parts arranged at positions corresponding to the three pillar parts of the first moving part (210_ph1) and three pillar parts arranged at positions corresponding to the three pillar parts of the second moving part (210_ph2).

[0140] The first type cushion bracket (230_ch1) may have a structure similar to the cushion bracket (230) described in the preceding drawings. For example, the first type cushion bracket (230_ch1) may include a first mounting portion (230_r1) on which one end (e.g., y-axis edge portion) of the first moving portion (210_ph1) disposed on the first driving device portion (210_1) is mounted. In addition, the first type cushion bracket (230_ch1) may include a second mounting portion (230_r2) on which one end (e.g., y-axis edge portion) of the second moving portion (210_ph2) disposed on the second driving device portion (210_2) is mounted. The first type cushion bracket (230_ch1) may include a structure without a separate hole (e.g., bracket fixing hole (230_hc) of FIG. 5) in the center. According to one embodiment, the first type cushion bracket (230_ch1) may include a first hole (e.g., a first through hole penetrating the y-axis and -y-axis or penetrating the front and rear) formed at a point of the first mounting portion (230_r1) and a second hole (e.g., a second through hole penetrating the front and rear) formed at a point of the second mounting portion (230_r2). The first type cushion structure (200_1) may further include a first fastening member (e.g., a bolt) that penetrates the first hole and is coupled with one end of the first moving part (210_ph1) to fix a portion of the first type cushion bracket (230_ch1) to the first moving part (210_ph1), and a second fastening member (e.g., a bolt) that penetrates the second hole and is coupled with one end of the second moving part (210_ph2) to fix another portion of the first type cushion bracket (230_ch1) to the second moving part (210_ph2). In this regard, grooves having female screw threads may be formed at the y-axis ends of the first moving part (210_ph1) and the second moving part (210_ph2) to be coupled with screw patterns formed on the first fastening member and the second fastening member.

[0141] The first type cushion bracket (230_ch1) may include a first sliding hole (230_h1) and a second sliding hole (230_h2). The first sliding hole (230_h1) may be used to couple one edge of the support bracket (220) described above in FIG. 10 or FIG. 11 with the first bracket fixing portion (240a). The second sliding hole (230_h2) may be used to couple the other edge of the support bracket (220) described above in FIG. 11 with the second bracket fixing portion (240b).

[0142] The first type cushion structure (200_1) described above can support adjusting (or changing) the inner curvature (e.g., the inner curvature observed when facing the -y axis in the y-axis direction) of the first part (230_ba1) of the first type cushion bracket (230_ch1) with the first driving device part (210_1), and adjusting (or changing) the inner curvature (e.g., the inner curvature observed when facing the -y axis in the y-axis direction) of the second part (230_ba2) of the first type cushion bracket (230_ch1) with the second driving device part (210_2). As described above, the first type cushion structure (200_1) supports adaptive deformation to suit various forehead shapes of a user by partially or independently controlling the degree of deformation (or the degree of change in the curvature of the inner curved surface) of the first part (230_ba1) (or at least a part of the first part (230_ba1)) and the second part (230_ba2) (or at least a part of the second part (230_ba2)) of the first type cushion bracket (230_ch1).

[0143] Meanwhile, in the above description, the structure in which the first driving device part (210_1) and the second driving device part (210_2) are arranged in parallel on the x-axis and the -x-axis is exemplified, but the cushion structure of the wearable electronic device according to the embodiment of the present disclosure is not limited thereto. For example, the driving device parts applied to the wearable electronic device are arranged at a certain interval on the z-axis or the -z-axis (or up and down), and correspondingly, the moving parts included in each driving device part and the driving parts supporting the linear movement thereof may be arranged up and down on the z-axis. When the moving parts are arranged up and down (or in the z-axis direction or in the -z-axis direction), the mounting parts arranged on one side of the cushion bracket (e.g., the side facing the -y-axis direction) may also be arranged in parallel while being spaced at a certain interval on the z-axis. Even in a structure where the moving parts are arranged at a certain interval along the z-axis, the driving parts may be arranged at a certain interval along the y-axis while being respectively arranged at the upper end of the driving body. Alternatively, in a structure where the moving parts are arranged at a certain interval along the z-axis, the driving parts may be arranged at a certain interval along the x-axis of the driving body.

[0144] Additionally or alternatively, the driving device parts of the first type cushion structure (200_1) may include four moving parts spaced apart at a certain interval in the up, down, left, and right directions, four driving parts controlling the linear movement of each of the moving parts, and four mounting parts formed on one surface of the first type cushion bracket (230_ch1) on which the four moving parts are mounted (or coupled to the cushion bracket through a fastening part).

[0145] Meanwhile, in the above description, in the first type driving device (210_t1), one side of the first driving body (210_ba_1) of the first driving device part (210_1) and the second driving body (210_ba_2) of the second driving device part (210_2) are connected to each other, but the first type cushion structure (200_1) according to the embodiment of the present disclosure is not limited thereto. For example, the first type cushion structure (200_1) may include a structure in which the first driving body (210_ba_1) and the second driving body (210_ba_2) are separated. For example, the first type driving device (210_t1) may include a separated first driving device and second driving device.

[0146] FIG. 15 is a drawing showing an example of a second type cushion structure according to one embodiment.

[0147] Referring to FIGS. 1 to 15, the second type cushion structure (200_2) may include a driving device (210), a first deformation support bracket (220_ch) (or a first type support bracket), and a second type cushion bracket (230_ch2) (or a second deformation cushion bracket).

[0148] The above driving device (210) may be substantially the same as or similar to the driving devices mentioned in FIGS. 1 to 12 above. For example, the driving device (210) may include a dial device (210_dial) that is provided to be rotatable, a shaft (210_sl) (or sliding part, sliding device) that is connected to the dial device (210_dial) and rotates clockwise or counterclockwise according to the operation of the dial device (210_dial) and has a gear pattern formed thereon. The shaft (210_sl) may be gear-coupled to one side of the moving part (210_ph). The driving device (210) having such a structure can move the moving part (210_ph) gear-coupled to the shaft (210_sl) in the y-axis direction (or -y-axis direction) when the dial device (210_dial) rotates clockwise (or counterclockwise) to rotate the shaft (210_sl). When the above moving part (210_ph) moves in a straight line, the end (e.g., y-axis edge) of the moving part (210_ph) may press one side (e.g., center) of the second type cushion bracket (230_ch2) in the y-axis direction, thereby causing deformation of one side of the second type cushion bracket (230_ch2).

[0149] The first deformation support bracket (220_ch) is at least partially disposed between the driving device (210) and the second type cushion bracket (230_ch2), and can support the second type cushion bracket (230_ch2). The first deformation support bracket (220_ch) may be substantially the same as or similar to the support bracket (220) mentioned above in FIGS. 1 to 13, except for the area where the elastic member (270) is disposed. For example, the x-axis or -x-axis edge of the first deformation support bracket (220_ch) may be coupled with both edges of the second type cushion bracket (230_ch2). While the center of the second type cushion bracket (230_ch2) is deformed and both edges of the second type cushion bracket (230_ch2) move in the -x-axis or x-axis direction, the first deformation support bracket (220_ch) can support the second type cushion bracket (230_ch2). According to one embodiment, the first deformation support bracket (220_ch) may include a first elastic member fixing portion (220_sp) to which the elastic member (270) is fixed. The first elastic member fixing portion (220_sp) may include a ring shape to which one edge (e.g., the -y-axis edge) of the elastic member (270) is fixed. Alternatively, the first elastic member fixing portion (220_sp) may include a soldering portion that fixes the elastic member (270) to the inside of the first deformation support bracket (220_ch). However, the embodiment of the present invention is not limited to the shape, type, or material of the first elastic member fixing portion (220_sp), and one side of the elastic member (270) may include at least one of various structures or materials that can be fixed to an inner portion of the first deformation support bracket (220_ch).

[0150] The second type cushion bracket (230_ch2) is at least partially disposed between the first deformation support bracket (220_ch) and the pad portion (e.g., the pad portion (260) mentioned in FIGS. 4 to 6), and can support the pad portion. The second type cushion bracket (230_ch2) may be substantially identical or similar to the cushion brackets (230, 230_ch1) mentioned in FIGS. 1 to 13, except for the area where the elastic member (270) is disposed. For example, the x-axis or -x-axis edge of the second type cushion bracket (230_ch2) may be coupled with both edges of the first deformation support bracket (220_ch). The second type cushion bracket (230_ch2) may have a different depth of depression in the -y-axis direction from the y-axis depending on the pressure of the moving part (210_ph), and thus the curvature of the center of the second type cushion bracket (230_ch2) may vary. Based on this, the second type cushion structure (200_2) may achieve closer contact with various types of user's foreheads. According to one embodiment, the second type cushion bracket (230_ch2) may include a second elastic member fixing portion (230_sp) to which the elastic member (270) is fixed. Similar to the first elastic member fixing portion (220_sp), the second elastic member fixing portion (230_sp) may include a ring shape or a soldering portion to which the other edge (e.g., the y-axis edge) of the elastic member (270) is fixed. However, the embodiment of the present invention is not limited to the shape, type, or material of the second elastic member fixing portion (230_sp), and one side of the elastic member (270) may include at least one of various structures or materials that can be fixed to an inner portion of the second type cushion bracket (230_ch2). Additionally or alternatively, the second elastic member fixing portion (230_sp) may be formed of a different structure and material from the first elastic member fixing portion (220_sp).

[0151] The second type cushion structure (200_2) of the above-described structure can have a moving part (210_ph) move linearly in the y-axis direction according to the operation of the driving part (210_di) of the driving device (210). In this process, the moving part (210_ph) can press the second type cushion bracket (230_ch2) in the y-axis direction. While the moving part (210_ph) moves in the -y-axis direction according to the operation of the driving part (210_di), the center of the second type cushion bracket (230_ch2) can return to its original shape by the elastic member (270). By applying the elastic member (270), the second type cushion structure (200_2) can omit the fastening structure that connects the moving part and the cushion bracket.

[0152] In the second type cushion structure (200_2) including the elastic member (270), the elastic member (270) and related structures may be applied to at least one of FIGS. 1 to 14 or FIG. 16 described below. According to one embodiment, the cushion structure may include a plurality of elastic members arranged between the support bracket and the cushion bracket.

[0153] Fig. 16 is a drawing illustrating an example of a third type cushion bracket according to one embodiment. The third type cushion bracket (230_ch3) described in Fig. 16 can replace the cushion brackets previously mentioned in Figs. 1 to 5.

[0154] Referring to FIGS. 1 to 16, the third type cushion bracket (230_ch3) may include, for example, a central bracket (230_ba_c), a first side bracket (230_ba_1), a second side bracket (230_ba_2), a first joint structure (230_jo1), and a second joint structure (230_jo2).

[0155] The central bracket (230_ba_c) may be positioned between the first side bracket (230_ba_1) and the second side bracket (230_ba_2). The central bracket (230_ba_c) may have, for example, a concave shape that is curved in the -y-axis direction from the y-axis. For example, the central bracket (230_ba_c) may have a concave shape from the bottom to the top, and a concave shape from the left to the right or from the right to the left. The central bracket (230_ba_c) may be formed to have the same or similar thickness overall regardless of the position. When a point of the central bracket (230_ba_c) is pressed, its shape may be deformed based on the point. For example, when a physical pressure is applied from the outside to the central mounting portion (230_rsc) corresponding to the center of the central bracket (230_ba_c), the center of the central bracket (230_ba_c) may be physically deformed. For example, the degree of concaveness of the center of the central bracket (230_ba_c) may be deformed in response to the pressure applied through the central mounting portion (230_rsc). The central mounting portion (230_rsc) may be arranged on one surface (e.g., the surface facing the -y-axis direction) of the central bracket (230_ba_c). One end (e.g., the y-axis edge) of a moving portion (e.g., the moving portion mentioned in FIGS. 1 to 15) may be mounted (or inserted, fixed) on the central mounting portion (230_rsc). In this regard, the central mounting portion (230_rsc) has a cylindrical shape protruding in the -y-axis direction from one side of the central bracket (230_ba_c), and a groove may be formed in the center where one end of the moving portion can be mounted. In the illustrated drawing, a structure in which one central mounting portion (230_rsc) is disposed is exemplified, but the present disclosure is not limited thereto, and a plurality of mounting portions may be disposed.Additionally or alternatively, a through hole (e.g., a hole penetrating from the y-axis to the -y-axis) is disposed in an area of ​​the central bracket (230_ba_c) on which the central mounting portion (230_rsc) is disposed, and the cushion structure including the third type cushion bracket (230_ch3) may further include a central fastening portion (e.g., a bolt) that penetrates the through hole and is fastened to one end of the moving portion mounted on the central mounting portion (230_rsc).

[0156] The first side bracket (230_ba_1) may be connected to the central bracket (230_ba_c) through the first joint structure (230_jo1). The area of ​​the first side bracket (230_ba_1) may increase from one edge (e.g., in the x-axis direction) toward the first joint structure (230_jo1) (or in the -x-axis direction). The thickness of the first side bracket (230_ba_1) may be the same as or similar to the thickness of the central bracket (230_ba_c). The first side bracket (230_ba_1) may have a shape that is bent in the -y-axis direction. The x-axis edge of the first side bracket (230_ba_1) may be arranged to protrude further in the y-additional direction than the -x-axis edge of the first side bracket (230_ba_1). A first side mounting portion (230_rs1) having a cylindrical shape protruding in the -y-axis direction and having a groove formed in the center thereof may be disposed on one side (e.g., a side facing the -y-axis direction) of the first side bracket (230_ba_1). One end of the moving portion may be mounted (or inserted or fixed) on the first side mounting portion (230_rs1). According to various embodiments, the first side mounting portion (230_rs1) may be omitted, and correspondingly, one end of the moving portion mounted on the first side mounting portion (230_rs1) may also be omitted. The first side bracket (230_ba_1) may include a first sliding hole (230_h1) penetrating from the y-axis direction to the -y-axis direction. The above first sliding hole (230_h1) is formed at the x-axis edge of the first side bracket (230_ba_1), and at least a part of the first bracket fixing part described above (e.g., the first bracket fixing part (240a) of FIG. 4) can be inserted.The first bracket fixing part (e.g., the first bracket fixing part (240a) of FIG. 4) can be coupled with one side of the support bracket (220) (e.g., the first bracket connecting part (220_bos1) of FIG. 5) by passing through the first sliding hole (230_h1), and can be slid in the first direction (e.g., the x-axis direction or the -x-axis direction) along the first sliding hole (230_h1).

[0157] The second side bracket (230_ba_2) may be connected to the central bracket (230_ba_c) through the second joint structure (230_jo2). The area of ​​the second side bracket (230_ba_2) may increase from one edge (e.g., -x-axis direction) toward the second joint structure (230_jo2) (or x-axis direction). The second side bracket (230_ba_2) is positioned symmetrically with respect to the first side bracket (230_ba_1) with respect to the central bracket (230_ba_c), and may have a shape symmetrical with respect to the first side bracket (230_ba_1). The thickness of the second side bracket (230_ba_2) may be the same as or similar to the thickness of the central bracket (230_ba_c) or the thickness of the first side bracket (230_ba_1). The -x-axis edge of the second side bracket (230_ba_2) may be arranged to protrude further in the y-additional direction than the x-axis edge of the second side bracket (230_ba_2). A second side mounting portion (230_rs2) having a structure similar to or identical to the first side mounting portion (230_rs1) may be arranged on one side (e.g., a side facing the -y-axis direction) of the second side bracket (230_ba_2). One end of the moving portion may be mounted (or inserted, fixed) on the second side mounting portion (230_rs2). According to various embodiments, the second side mounting portion (230_rs2) may be omitted together with the first side mounting portion (230_rs1), and correspondingly, one end of the moving portion mounted on the second side mounting portion (230_rs2) may also be omitted. The second side bracket (230_ba_2) may include a second sliding hole (230_h2) that penetrates from the y-axis direction to the -y-axis direction. The second sliding hole (230_h2) is formed at the -x-axis edge of the second side bracket (230_ba_2), and at least a portion of the second bracket fixing part described above (e.g., the second bracket fixing part (240b) of FIG. 4) may be inserted.The second sliding hole (230_h2) is positioned symmetrically with respect to the first sliding hole (230_h1) with respect to the central bracket (230_ba_c), and may have the same or similar size and shape as the first sliding hole (230_h1). The second bracket fixing part (e.g., the second bracket fixing part (240b) of FIG. 4) may pass through the second sliding hole (230_h2) and be coupled with one side of the support bracket (220) (e.g., the second bracket connecting part (220_bos2) of FIG. 5), and may slide in a second direction (e.g., the -x-axis direction or the x-axis direction) along the second sliding hole (230_h2).

[0158] The first joint structure (230_jo1) may connect the first side bracket (230_ba_1) to the central bracket (230_ba_c) so that the first side bracket (230_ba_1) can move in a certain direction (e.g., in the y-axis direction or the -y-axis direction). In this regard, the first joint structure (230_jo1) may include at least one joint structure.

[0159] The second joint structure (230_jo2) may connect the second side bracket (230_ba_2) to the central bracket (230_ba_c) so that the second side bracket (230_ba_2) can move in a certain direction (e.g., the y-axis direction or the -y-axis direction). In this regard, the second joint structure (230_jo2) may include at least one joint structure. As an example, the second joint structure (230_jo2) may have a structure identical to or similar to that of the first joint structure (230_jo1). The second joint structure (230_jo2) may be arranged at a position symmetrical to the first joint structure (230_jo1) with respect to the center of the central bracket (230_ba_c).

[0160] Additionally or alternatively, one side of the central bracket (230_ba_c) (e.g., the side facing the -y-axis direction or the side facing the main body) may be provided with mounting portions on which moving portions included in the plurality of driving device parts (or driving devices) described above in FIG. 14 may be mounted (or inserted, fixed). For example, based on the user's manipulation of each of the driving device parts, the central bracket (230_ba_c) may support independent deformation in the y-axis direction at a plurality of points or linked deformation at a plurality of points. Accordingly, the wearable electronic device of the present disclosure may support close contact with the cushion structure for each of the user's foreheads having three-dimensionally different shapes.

[0161] The third type cushion bracket (230_ch3) described above can be applied to the cushion structures mentioned in FIGS. 1 to 15, and the cushion structure applying the third type cushion bracket (230_ch3) can support deformation or restoration of the central bracket (230_ba_c) with relatively less pressure on the moving part compared to other cushion brackets (e.g., the cushion brackets mentioned in FIGS. 1 to 15). As described above, the cushion structure according to the embodiment of the present disclosure can partially deform or fit the cushion bracket to fit the user's head shape (convex or flat), thereby providing a more stable and comfortable wearing experience and reducing the occurrence of pain or discomfort even when used for a long time. In addition, the cushion structure of the present invention can finely adjust the degree of concaveness of the cushion bracket by using a wheel (or dial)-shaped driving part, or can support various shape deformations of the cushion bracket by pushing or pulling specific points.

[0162] According to various embodiments, in relation to handling or dissipating heat generated during the weight or operation of the wearable electronic device, the first side bracket (230_ba_1), the second side bracket (230_ba_2), and the central bracket (230_ba_c) may be composed of different materials.
