According to various embodiments, coupling parts that protrude outward and may be coupled to the front case 122 by a coupling device (for example, a screw) may be provided on opposite side walls of the slider cap 525. At least one recess in which the slide support 526 is seated to be fixed may be arranged at a lower portion of the slider cap 525. According to an embodiment, a plurality of recesses may be arranged in an area of a lower portion of the slider cap 525, in which the slide support 526 is arranged such that the connecting slider 524 is prevented from being horizontally moved by a force applied only horizontally. For example, while the slider cap 525 and the slide support 526 are coupled to at least one of the plurality of recesses, the plurality of recesses may function as stopping elements that prevent horizontal movement of the connecting slider 524. Further, while the slide support 526 is moved vertically downward and is separated from the plurality of recesses, the plurality of recesses may allow the connecting slider 524 to be horizontally moved.
The slide support 526, for example, may include a hole that may be coupled to at least one column provided in the slide button 521. Further, the slide support 526 may be horizontally moved along a through-hole provided in the slider cap 525 while being coupled to the columns. According to an embodiment, the slide support 526 may include at least one protrusion that protrudes upwards (for example, towards the slider cap 525). The protrusion may be released from or coupled to the plurality of recesses provided on one side of the slider cap 525 by applying an external pressure or removing an external pressure applied vertically downwards (for example, towards the facial side of the main frame 110).
FIG. 6B is a view illustrating a connector holder in a first state according to an embodiment of the present disclosure.
Referring to FIG. 6B, the connector holder 500 may include a binder 510 and a support member 520. The binder 510, for example, may be arranged to surround one side of the electronic device 200. The connector arranged in the binder 510 may be electrically connected to the electronic device 200. The binder 510 may exert a resilient force against a rotation in one direction while the first resilient member 513 is coupled to the connecting slider 524. Accordingly, after rotating the binder 510 upwards by a specific angle, the electronic device 200 may be inserted into the connector arranged in the binder 510 while the binder 510 is maintained to indicate an upward direction by applying a constant pressure. At least one textured protrusion (or a textured boss e.g., wrinkle boss) is arranged at an upper end of the binder 510 so that a frictional force against a finger of the user may be increased when the binder 510 is rotated or horizontally moved. As illustrated, the indicator 516 may be arranged on one side of the connecting slider 524. A location of the indicator 516 may be changed in response to the horizontal movement of the connecting slider 524.

Referring to FIGS. 6C and 6D, in relation to the first state of the connector holder 500, the connector 514 may be arranged horizontally (for example, in a direction parallel to the bottom of the seating area 122a of the front case 122). In this state, the slide support 526 may be arranged at a first location of the lower end of the slider cap 525. A plurality of recesses, for example, a first recess 525a and a second recess 525b may be provided one side of a lower portion of the slider cap 525. The first recess 525a may be used, for example, when the slider cap 525 is coupled to a first type of electronic device, and the second recess 525b may be used, for example, when the slider cap 525 is coupled to a second type of electronic device. According to various embodiments, two or more recesses may be arranged at a lower portion of the slider cap 525 according to the type of the electronic device supported by the HMD device 100. Further, the interval and shape of the recesses arranged at a lower portion of the slider cap 525 may vary according to the types of the electronic devices supported by the HMD device 100.
The second resilient member 523 may be arranged between the slider cap 525 and the connecting slider 524 while being coupled to the columns of the slide button 521. In this state, if an external pressure is applied in a direction perpendicular to the direction in which the connector 514 is arranged, the second resilient member 523 may be urged downwards. While the second resilient member 523 is compressed, the slide support 526 connected to the column of the slide button 521 may be separated from the recess of the slider cap 525. In this state, if an external pressure is applied horizontally (for example, in a horizontal direction in which the connector 514 is arranged), the binder 510 may horizontally be moved.
If the external pressure is removed after the binder 510 is horizontally moved, the slide button 521 may return to the original position while the second resilient member 523 is restored. Accordingly, the slide support 526 connected to the slide button 521 may be coupled to a recess at a location that is different from the previous one.
FIG. 6E is a view illustrating a movement state of a connector holder according to an embodiment of the present disclosure.
Referring to FIG. 6E, the connector holder 500 may be in a horizontal state and a rotation state as illustrated. In the horizontal state, the connector 514 of the connector holder 500 may be arranged parallel to the bottom of the seating area 122a of the front case 122. In the rotation state, the connector 514 may be arranged to indicate a direction that is inclined by a specific angle with respect to the bottom of the seating area 122a of the front case 122.
The connector holder 500 may be rotated through a rotary shaft 530. The aforementioned first resilient member 513 may be coupled to the rotary shaft 530. The rotary shaft 530 may be coupled to the ring 524a provided in the connecting slider 524. The connector holder 500 may be operated to return to the horizontal state by a resilient force of the first resilient member 513.
FIG. 6F is a view illustrating a cutaway surface of a connector holder in a third state according to an embodiment of the present disclosure.
Referring to FIG. 6F, the connector holder 500 may be arranged to have a specific inclination from the bottom of the seating area 122a of the front case 122 while further protruding to the seating area 122a of the front case 122. According to an embodiment, in relation to a third state, the connector holder 500 may be in a third state while an external pressure of not less than a specific magnitude (for example, an external pressure of not less than a resilient force for restoring the first resilient member 513) is maintained.
In this regard, the connector holder 500 may be horizontally movable by a pressure applied vertically and horizontally. After being horizontally moved, the connector holder 500 may be arranged to be inclined towards the seating area 122a of the front case 122 (or arranged in the seating area 122a at a location that is spaced apart from the peripheral area 122b by a distance). Thereafter, if an external pressure is applied in a rotational direction (for example, an upward direction from the bottom of the seating area 122a of the front case 122 (or a curving direction toward the peripheral area 122b)), the connector holder 500 may be in the third state as illustrated. The third state, for example, may correspond to a location related to coupling of a first type (or second type) of electronic device. In this regard, as the indicator 516 of the connector holder 500 indicates a specific location of the indication part 800 (for example, a print area that represents the type of the electronic device), the user may determine a location of the connector holder 500 related to the type of the electronic device by identifying a location of the corresponding indicator 516 and the print area 820.
FIG. 6G is a view illustrating a cutaway surface of a connector holder in a fourth state according to an embodiment of the present disclosure.
Referring to FIG. 6G, the connector holder 500 may be arranged to have a specific inclination from the bottom of the seating area 122a of the front case 122 in a state in which it is inclined towards the peripheral area 122b of the front case 122 (or a state in which it deviates from the seating area 122a). According to an embodiment, in relation to a fourth state, the connector holder 500 may be in a fourth state while an external pressure of not less than a specific magnitude (for example, an external pressure of not less than a resilient force for restoring the first resilient member 513) is maintained.
In this regard, the connector holder 500 may be moved horizontally (for example, from the seating area 122a towards the peripheral area 122b). After being horizontally moved, the connector holder 500 may be arranged to be inclined towards the peripheral area 122b of the front case 122. Thereafter, if an external pressure is applied in a rotational direction by a specific angle, the connector holder 500 may be in a fourth state as illustrated. The fourth state, for example, may correspond to a location related to coupling of a second type (or first type) of electronic device. In this regard, as a specific location (for example, a print area 820) of the indication part 800 (for example, a print area 820 that represents the type of the electronic device) is indicted as the indicator 516 is exposed at a location at which the connector holder 500 is arranged, the user may determine a location of the connector holder 500 related to the type of the electronic device by identifying a location of the corresponding indicator 516 and the print area 820.
FIG. 6H is an exploded perspective view of a connector holder and a front case according to an embodiment of the present disclosure.
Referring to FIG. 6H, the connector holder 500 may be inserted from the rear surface of the front case 122 towards the front surface of the front case 122 to be fixed. In this regard, the front case 122 may include a connector holder hole 123 such that at least a portion of the connector holder 500 is exposed to the front side. The binder 510 of the connector holder 500 may be arranged to protrude from a peripheral portion of one side of the front case 122 through the connector holder hole 123. According to various embodiments, after the connector holder 500 is mounted in the connector holder hole 123, the connector holder 500 may be fixed to the connector holder hole 123 through a coupling device (for example, a hook or screw).
As illustrated, the connector holder 500 may include a slider cap 525 that has a rear surface coupled to any one of the recesses provided in the slide support 526. In the coupling process, an area in which the first resilient member 513 of the connector holder 500 is arranged may be covered by the peripheral area 122b of the front case 122.
FIG. 7A is a view illustrating a fixing holder of a front case of the HMD device in a first state according to an embodiment of the present disclosure.
Referring to FIG. 7A, in the HMD device 100, the lens hole 270 may be arranged at the center of the seating area 122a of the front case 122, and the connector holder 500 and the fixing holder 600 may be arranged at peripheral portions of the lens hole 270. The fixing holder 600, for example, may be horizontally movable towards a central portion of the seating area 122a of the front case 122 or from the seating area 122a of the front case 122 towards the peripheral area 122b. According to an embodiment, as illustrated, when a separate external pressure is not applied, the fixing holder 600 may be in a first state in which it is inclined towards the seating area 122a. Although it is illustrated in the drawing that the connector holder 500 is inclined towards the peripheral area 122b, the connector holder 500 may be horizontally moved by a pressure applied vertically and horizontally as described above.
FIG. 7B is a view illustrating the fixing holder of the front case of the HMD device in a second state according to an embodiment of the present disclosure.
Referring to FIG. 7B, the HMD device 100 may include a connector holder 500 and a fixing holder 600 that are arranged around the seating area 122a in which a lens hole 270 is arranged. The fixing holder 600, for example, may be horizontally movable in a direction farther from the central portion of the seating area 122a of the front case 122 (or towards the peripheral area 122b). According to an embodiment, when an external pressure of not less than a magnitude is applied horizontally with respect to the bottom of the seating area 122a of the case 122, the fixing holder 600 may be in a second state in which it is inclined in a direction in which it moves farther from the seating area 122a or towards the peripheral area 122b as illustrated. The second state may be maintained while the external pressure is maintained. If the external pressure is released, the fixing holder 600, for example, may be horizontally movable towards a central portion of the seating area 122a of the front case 122. Although it is illustrated in the drawing that the connector holder 500 is inclined towards the peripheral area 122b, the connector holder 500 may be horizontally moved by a pressure applied vertically and horizontally.
FIG. 7C is a view illustrating the fixing holder of the front case of the HMD device in a third state according to an embodiment of the present disclosure.
Referring to FIG. 7C, the HMD device 100 according to an embodiment may include a connector holder 500 and a fixing holder 600 that are arranged around the seating area 122a in which a lens hole 270 is arranged. The fixing holder 600, for example, may be horizontally moved in a direction farther from the central portion of the seating area 122a of the front case 122 (or towards the peripheral area 122b). While the fixing holder 600 is horizontally moved towards the peripheral area 122b, a resilient force of the resilient member arranged in the fixing holder 600 may increase.
According to an embodiment, when an external pressure of not less than a magnitude is horizontally provided with respect to the bottom of the seating area 122a of the front case 122 such that the second state described with reference to FIG. 7B is established and then an external pressure of not less than a magnitude is additionally applied, the fixing holder 600 may be rotated to a specific inclination with the bottom of the seating area 122a of the front case 122 at a location in the second state. Accordingly, as illustrated, the fixing holder 600 may be parallel to the bottom of the seating area 122a of the front case 122 and then may be in a third state in which it is inclined at a specific inclination from the bottom of the seating area 122a as it rotates. According to various embodiments, when a separate external pressure (for example, a force applied from the peripheral area 122b of the front case 122 towards a central portion of the seating area 122a) is not provided, the third state may be maintained. In this regard, the third state may be maintained by coupling the fixing holder 600 to a stopping element arranged in the peripheral area 122b such that the fixing holder 600 may resist against a resilient force of the resilient member. The connector holder 500 may be horizontally moved by a pressure applied vertically and horizontally.
FIG. 8A is an exploded perspective view of a fixing holder according to an embodiment of the present disclosure.
Referring to FIG. 8A, the fixing holder 600 may include a holder part 610 and a support part 620. The holder part 610 may include a fixing part body 611 and a fixing part slider 612. The support part 620 may include a third resilient member 621, a holder cap 623, and a fixing part support 625.
The fixing part body 611, for example, may include a curved part 611a that forms a curved surface in a specific angle range as a whole while an outer contour has a specific width, a support bar 611b that extends from a lower end of the curved part 611a in the first direction (for example, towards the seating area 122a of the front case 122) while having a specific width, a stopping element 611c that extends from a lower side of the support bar 611b in the second direction (for example, a direction perpendicular to the bottom surface of the support bar 611b), a protrusion 611d that protrudes from a lower end of the curved part 611a in the second direction (for example, vertically downwards or towards the facial side of the front case 122), and a connecting shaft 611e arranged on a side surface of the curved part 611a.
One side of the curved part 611a, for example, an upper end of the curved part 611a may be rounded. Further, a texture may be formed on at least a portion of the surface of the curved part 611a. According to various embodiments, an upper end of the curved part 611a may include an area that has a hangover shape and protrudes in the first direction. Accordingly, the overall shape of the curved part 611a may have a hook shape.
The support bar 611b, for example, may have a shape a thickness of which gradually decreases as it goes in the first direction. The support bar 611b, for example, may be an area that faces a portion of a side surface of the electronic device 200 while the electronic device 200 is seated in the HMD device 100. As the support bar 611b protrudes in the first direction, the fixing holder 600 may have a C shape as a whole. Further, the fixing holder 600 has a C shape as a whole, and a protrusion at an upper end thereof may be shorter than a protrusion at a lower end thereof. Based this, the electronic device 200 avoids collision with the curved part 611a while facing the support bar 611b. The stopping element 611c may be arranged below the support bar 611b. The stopping element 611c may be arranged to be stopped by a depression or opening provided in the fixing part slider 612.
The protrusion 611d may protrude downward from a distal lower end of the curved part 611a, which is opposite to the first direction (or towards the facial side of the front case 122 to which the fixing holder 600 is coupled). The protrusion 611d may be multi-stepped such that steps having different thicknesses and widths are connected to each other. One side of the protrusion 611d (for example, a first step on the lower side of the drawing), for example, may be connected to one end of the third resilient member 621, and an opposite side of the protrusion 611d (a second step situated on the first step in the drawing) may be coupled to the holder cap 623. The protrusion 611d, for example, may function to fix one side of the third resilient member 621 to the fixing part body 611.
The connecting shaft 611e, for example, may extend by a specific thickness in a depth direction (or a direction in which it protrudes upwards from a surface of a side wall of the curved part 611a) with respect to a side wall of the curved part 611a. The connecting shaft 611e may be coupled to a connection hole 612c provided in the fixing part slider 612 to support a hinge motion (or a rotation within a specific angle range) of the fixing holder 600.
The fixing part slider 612 may include an opening or depression 612a in which the fixing part body 611 is seated, side walls 612b that surround the opening or depression 612a, connection holes 612c that are formed on sides of the side walls 612b to be coupled to the connecting shaft 611e, a first seating part 612d in which the stopping element 611c is seated, and a second seating part 612e in which the support bar 611b is seated. A plurality of connection holes 612c, for example, may be arranged. The first seating part 612d may be arranged inside the second seating part 612e. The first seating part 612d may be lower than the second seating part 612e with respect to the bottom of the fixing part slider 612. Accordingly, a step may be formed between the first seating part 612d and the second seating part 612e. According to various embodiments, a recess 612f in which the third resilient member 621 is arranged may be provided at a front end of the fixing part slider 612 (for example, a front end of the second seating part 612e).
One side of the third resilient member 621 may be coupled to one side of the fixing part body 611 (for example, the protrusion 611d) seated in the fixing part slider 612. Further, an opposite side of the third resilient member 621 may be coupled to a recess formed in the fixing part support 625. At least a portion of the third resilient member 621, for example, may include a spring shape that exerts a resilient force horizontally. Accordingly, a resilient force of the third resilient member 621 may increase while the fixing part body 611 and the fixing part slider 612 are moved horizontally (for example, towards the peripheral area 122b of the front case 122) based on the fixing part support 625 so that a resilient force is exerted such that the fixing part body 611 and the fixing part slider 612 are moved towards the seating area 122a of the front case 122. The third resilient member 621, for example, may include a ring that is coupled to the protrusion 611d and a ring that is coupled to the recess that is formed in the fixing part support 625.
The holder cap 623 may function to fix the third resilient member 621 such that one side of the third resilient member 621 is not separated after being coupled to the protrusion 611d. The holder cap 623, for example, may have a U shape. The holder cap 623, for example, may include a ring in which one side of the third resilient member 621 is seated and a coupling part that is coupled to the protrusion 611d.
The fixing part support 625 may include a ring in which one side of the third resilient member 621 is seated to be fixed. Further, the fixing part support 625 may include a rail groove such that the fixing part slider 612 is horizontally moved. A rail provided on the bottom of the fixing part slider 612 may be seated in the rail groove. Further, a coupling structure for fixing the fixing part support 625 may be arranged on one side of the fixing part support 625 (a side wall of the fixing part support 625). The coupling structure, for example, may be configured to fix one side of the front case 122 and the fixing part support 625 through a hook or a screw.
FIG. 8B is a view illustrating a first state of a fixing holder according to an embodiment of the present disclosure.
FIG. 8C is a perspective view illustrating a fixing holder in a first state according to an embodiment of the present disclosure.
Referring to FIGS. 8B and 8C, the fixing holder 600, for example, is moved horizontally while the holder part 610 is positioned on the support part 620. According to an embodiment, as described above, the third resilient member 621 arranged in the support part 620 may exert a resilient force in a direction in which the location of the holder part 610 is restored when the holder part 610 is moved in one direction, while connecting the holder part 610 and the fixing part support 625. The first state of the illustrated fixing holder 600 may correspond to a state in which the third resilient member 621 is contracted. Accordingly, the holder part 610 may be inclined towards the seating area 122a of the front case 122.
According to various embodiments, a hook 625a that is temporarily coupled to a lower end of the fixing part body 611 (or the curved part 611a) of the holder part 610 may be arranged on one side of the fixing part support 625 of the support part 620. The hook 625a, for example, may be coupled to the holder part 610 while the holder part 610 is rotated to a specific inclination after being moved towards a periphery of the support part 620. The hook 625a, for example, may have a triangular recess as a portion of a side wall of the hook 625a is cutaway inwards.
FIG. 8D is a view illustrating a fixing holder in a second state according to an embodiment of the present disclosure.
Referring to FIG. 8D, for example, if an external pressure is applied to one side of the fixing holder 600, the holder part 610 of the fixing holder 600 may be inclined towards the peripheral area 122b as illustrated. According to an embodiment, when a pressing object in contact with a portion of an upper end of the holder part 610 applies a force from a central portion of the seating area 122a of the front case 122 towards the peripheral area 122b, the holder part 610 may be horizontally moved rearwards (for example, towards the peripheral area 122b) along the rail of the support part 620.
In the above-described state, a resilient force of the third resilient member 621 may increase as it is extended by a specific length. If the external pressure by which the holder part 610 is moved towards the peripheral area 122b is released, the holder part 610 may return to the state of FIG. 8B.
FIG. 8E is a view illustrating a movement state of a fixing holder according to an embodiment of the present disclosure.
Referring to FIG. 8E, the fixing holder 600 may be rotated within an angle in a direction with respect to the fixing shaft 630. For example, while the holder part 610 of the fixing holder 600 is moved to the location described in FIG. 8D, the holder part 610 of the fixing holder 600 may be rotated while being inclined with respect to the bottom of the front case 122. When the holder part 610 is rotated, the holder part 610 may maintain a rotation state even though a separate external pressure is not applied while one side of the holder part 610 (for example, one side of the fixing part body 611) is coupled to the hook 625a. As the holder part 610 is rotated, the bottom of the seating area 122a of the front case 122 may be inclined at a specific upward inclination while the support bar 611b is horizontally positioned.
According to various embodiments, if the external pressure is released or the coupling state of the hook 625a and the holder part 610 is released, the holder part 610 may automatically return to the first state. Further, if an external pressure towards the peripheral area 122b is maintained while an external pressure for releasing the coupling state of the hook 625a and the holder part 610 is applied, the holder part 610 may be in the second state (for example, a state in which the holder part 610 is inclined towards the peripheral area 122b).
FIG. 8F is a view illustrating a first cutaway surface C-C' of a connector holder in a second state according to an embodiment of the present disclosure.
Referring to FIG. 8F, the fixing holder 600 may include a holder part 610 and a support part 620. When the external pressure applied to the holder part 610 is applied towards the peripheral area 122b of the front case 122, the holder part 610 may be moved towards the peripheral area 122b. In this case, the third resilient member 621 may have an increased resilient force while being extended as compared with the initial state. If the external pressure is released in this state, the holder part 610 may return to the previous state (for example, the state of the holder part 610 of FIG. 8B).
FIG. 8G is a view illustrating a first cutaway surface C-C' of a connector holder in a third state according to an embodiment of the present disclosure.
FIG. 8H is a view illustrating a second cutaway surface D-D' of a connector holder in a third state according to an embodiment of the present disclosure.
Referring to FIGS. 8G and 8H, the fixing holder 600 may include a holder part 610 and a support part 620. If the external pressure applied to the holder part 610 is further increased towards the peripheral area 122b of the front case 122 or an external pressure in a curved form that is deflected towards the facial side of the front case 122 is generated, the holder part 610 may be inclined at a specific inclination as illustrated. In this state, even though one side of a lower end of the holder part 610 is coupled to the hook 625a and a separate external pressure is not applied, the holder part 610 may maintain the third state (for example, an inclined state). In this operation, a resilient force may be exerted towards a central portion of the seating area 122a of the front case 122 while the third resilient member 621 is extended as compared with the initial state. According to various embodiments, the holder part 610 may maintain the third state even though the resilient force is exerted while the holder part 610 is coupled to the hook 625a. According to various embodiments, when a force is applied to the holder part 610 towards a central portion of the seating area 122a of the front case 122, the holder part 610 may return to the first state of FIG. 8B by the resilient force of the third resilient member 621. The force, for example, may include a force applied such that a lower end of the holder part 610 is separated from the hook 625a.
FIG. 8I is an exploded perspective view of a fixing holder and a front case according to an embodiment of the present disclosure.
Referring to FIG. 8I, the front case 122 may include a lens hole 270 in which a lens is arranged, a connector holder hole 123 in which the connector holder 500 is arranged, and a fixing holder hole 124 in which the fixing holder 600 is seated. The connector holder hole 123 and the fixing holder hole 124 may be arranged at locations that are symmetrical to each other with respect to the lens hole 270.
The fixing holder hole 124, for example, may correspond to the size of the fixing holder 600. According to an embodiment, a structure that is coupled to the coupling structure arranged in the fixing holder 600 may be arranged at a peripheral portion of the fixing holder hole 124. For example, at least one boss for screw coupling may be arranged in the front case 122 around the fixing holder hole 124.
As illustrated, the rear surface of the fixing holder 600 may include a space such that the third resilient member 621 may be extended and compressed. Further, an interior space that is larger than the seating area 122a may be provided on a side of the fixing holder 600, which is close to the peripheral area 122b, to be operated in the third state. Accordingly, a part of the fixing holder 600, which is close to the peripheral area 122b, may protrude further than a part of the fixing holder 600, which is close to the seating area 122a.
According to various embodiments, a head mounted display device may include a main frame which includes a lens, and a front case including a seating area in which an electronic device is seated, and a peripheral area that surrounds at least a portion of a periphery of the electronic device, and may further include at least one of a connector holder that is horizontally moved from one side of the peripheral area with respect to a bottom of the seating area of the front case and that is electrically connected to a connection port of the electronic device while surrounding at least a portion of one side of the electronic device when the electronic device is mounted, and a fixing holder that is horizontally moved from one side of the peripheral area with respect to the bottom of the seating area of the front case and that surrounds a portion of an opposite side surface of the electronic device when the electronic device is mounted.
