Description

Technical Field

[0001] This invention relates to a wearable device. Background Technology

[0002] Recently, with the development of electronic technology, various devices have been developed to display visual information to users. As part of this, display devices that can be worn on the user's head are under development.

[0003] For example, a head-mounted display device (HMD) is a display device capable of displaying visual information while being worn on a user's head. Such HMD devices include virtual reality devices or augmented reality devices, where the virtual reality device displays the virtual reality world through a display unit positioned at the user's eyes when worn, and the augmented reality device displays an augmented reality world through the same display unit.

[0004] This type of HMD device requires a power supply to drive the display unit. Therefore, the HMD device receives commercial power via a power cord or receives power from a battery built into the device itself.

[0005] However, since using commercial power supplied via a power cord as the driving power source limits the user's flexibility, the method of having the device itself built-in battery has become the main way to provide driving power.

[0006] Therefore, to allow users to use HMD devices for extended periods, batteries with high storage capacity need to be installed in the HMD device. However, as the battery storage capacity increases, its size also increases. Consequently, because additional space is required inside the HMD device to install a larger capacity battery, the overall size of the HMD device also increases.

[0007] Furthermore, since design freedom decreases as the space available for battery installation increases, it can become a factor that inhibits design diversity. Summary of the Invention

[0008] Technical issues

[0009] The present invention addresses the aforementioned problems and aims to provide wearable devices that achieve lightweight design and design versatility while increasing battery capacity.

[0010] Technical solutions

[0011] To address the aforementioned problems, the present invention provides a wearable device comprising: a main body including an augmented reality or virtual reality display unit; a wearing part for maintaining the main body in a wearing state such that the display unit is positioned on the user's face; a battery part, coupled to the wearing part, and including a first battery that functions as a main battery and provides driving power to the main body, and a second battery that functions as an auxiliary battery to assist the first battery; and an operation part disposed on the wearing part so that the second battery can be detached from the wearing part during user operation.

[0012] Furthermore, the wearing part may include a frame formed in a ring shape to surround the user's head, wherein the frame may include: an arc-shaped first frame, one side of which is connected to the main body and combined with the first battery; an arc-shaped second frame, both ends of which are respectively locked to the ends of the first frame and have the operating part; and a receiving groove formed in the second frame to receive the second battery.

[0013] Furthermore, the wearable device may also include a support member, wherein the second battery is built into the support member, the support member being detachably coupled to the receiving slot.

[0014] Furthermore, the wearable device may also include a cover member, which is combined with the first frame to protect the first battery disposed on a surface of the first frame from external environmental influences.

[0015] Furthermore, the main body may not include a battery used as a driving power source.

[0016] Furthermore, the wearing part may also include a plate-shaped support member that is combined with the first frame, the support member being formed as a curved surface with a predetermined area to surround a portion of the user's head.

[0017] Furthermore, the first battery and the second battery can be flexible batteries.

[0018] Here, the flexible battery may include: an electrode assembly; an external material for sealing the electrode assembly and an electrolyte together; a first pattern formed on the electrode assembly such that peaks and valleys are repeatedly arranged along the length direction of the electrode assembly; and a second pattern formed on the external material such that it coincides with the second pattern along the length direction of the external material.

[0019] The effects of the invention

[0020] According to the present invention, by using a thin, flexible battery with a relatively light unit capacitance as the driving power source, the total weight can be reduced.

[0021] Furthermore, in this invention, a portion of the battery can be detachably attached to the wearing part. Therefore, since the wearable device according to an embodiment of the invention allows for easy replacement of a portion of the battery when the power is depleted, its usage time can be increased.

[0029] In the following, embodiments of the invention will be described in detail with reference to the accompanying drawings to enable those skilled in the art to readily implement the invention. The invention can be implemented in various different forms and is not limited to the embodiments described herein. For clarity of description, parts irrelevant to the description have been omitted from the drawings, and throughout the specification, the same reference numerals are used to denote the same or similar components.

[0030] According to one embodiment of the present invention, the wearable device 100 may be a head-mounted display (HMD) device for realizing visual virtual reality or augmented reality.

[0031] When a user wears the wearable device 100 on their head, the display unit 112 can be positioned corresponding to the user's eyes, and the user can view various information or images displayed through the display unit 112.

[0032] Therefore, such as Figures 1 to 4 As shown, a wearable device 100 according to an embodiment of the present invention may include a main body 110, a wearing part 120, a battery part 130a and 130b, and an operation part 140.

[0033] When a user wears the wearable device 100 on their head via the wearing part 120, the main body 110 can be positioned corresponding to the user's eyes.

[0034] This main body 110 can provide users with various image information.

[0035] Therefore, such as Figure 1 As shown, the main body 110 may include a display unit 112 for displaying various image information, and may include a control unit for controlling the driving of the display unit 112.

[0036] The control unit may be a microprocessor, and the display unit 112 may be an augmented reality display that outputs augmented reality or a virtual reality display that outputs virtual reality.

[0037] In addition, the display unit 112 may be a transparent organic light-emitting display.

[0038] Therefore, while viewing the information or images output through the transparent organic light-emitting display, users can experience augmented reality that overlays the real world through the transparent organic light-emitting display, or experience virtual reality that mimics a specific environment or situation in reality so that it appears to interact with the real surroundings or environment through the display unit 112.

[0039] In addition to the display unit 112, the main body 110 may also include other functional modules for performing various functions. For example, the main body 110 may also include a communication module for wirelessly transmitting / receiving data; various sensor modules for detecting the user's gestures, movements, temperature, speed, etc.; and at least one of a camera module, a microphone module, and a speaker module for acquiring image information of the user's surroundings.

[0040] Furthermore, the main body 110 may also include a data storage unit for storing information obtained through the above-described functional modules, and may include a USB port for connecting to an external storage medium, etc.

[0041] As described above, when a user wears a wearable device 100 according to an embodiment of the present invention, the wearing part 120 can fix the main body part 110, such that the main body part 110 is positioned in front of the user's face.

[0042] For example, the wearing part 120 may be configured as a ring-shaped frame to wrap around the user's head when wearing the wearable device 100.

[0043] As a non-limiting example, the frame may include: an arc-shaped first frame 121, one side of which is connected to the main body 110; and an arc-shaped second frame 122, both ends of which are respectively locked to the ends of the first frame 121, wherein the first frame 121 and the second frame 122 may be configured to protrude in opposite directions to each other.

[0044] Therefore, the frame can be formed into a ring by combining the first frame 121 and the second frame 122. When the user wears it, one surface of the first frame 121 and one surface of the second frame 122 come into contact with the user's head, thereby surrounding the user's head.

[0045] Therefore, when a user wears a wearable device 100 according to an embodiment of the present invention, the wearing part 120 can surround the user's head, and the main body part 110 connected to one side of the first frame 121 can be placed on the front side of the user's face.

[0046] Here, the two ends of the second frame 122 can be fixedly connected to the ends of the first frame 121, or they can be rotatably connected relative to the first frame 121.

[0047] In this case, in a wearable device 100 according to an embodiment of the present invention, the wearing part 120 can be configured to wrap around the user's head to prevent the wearing state from being released due to slipping down.

[0048] For this purpose, the wearing part 120 may also include a plate-shaped support member 125 that is coupled to the first frame 121. Such a support member 125 may be configured to have a predetermined area to surround a portion of the user's head, and may be formed as a curved surface to make close contact with the user's head.

[0049] Therefore, when a user wears the wearable device 100 according to an embodiment of the present invention, the first frame 121 and the second frame 122 can surround the user's head, and the support member 125 can contact the upper part of the user's head. Thus, when the first frame 121 and the second frame 122 are worn on the user's head, the support member 125 can prevent them from slipping down.

[0050] The battery units 130a and 130b can function as power supply sources that provide drive power to the main body unit 110.

[0051] That is, the battery units 130a and 130b provide driving power to the control unit (not shown) built into the main body 110, so that various functional modules including the display unit 112 in the main body 110 are driven by the control unit.

[0052] The battery units 130a and 130b can be built into the side of the wearing part 120 to prevent the center of gravity from being concentrated on the main body part 110 side for the front of the face when wearing the wearable device 100 according to an embodiment of the present invention. The battery units 130a and 130b can be made of flexible batteries that reduce the overall weight and have high capacity.

[0053] That is, in a wearable device 100 according to an embodiment of the present invention, the battery units 130a and 130b may be built inside the wearing part 120 surrounding the user's head instead of being built into the main body 110, so as to maintain the wearing state of the main body 110.

[0054] As an example, the battery sections 130a and 130b are composed of at least one flexible battery and can be combined with the wearing section 120 to be arranged along the length direction of the first frame 121 and / or the second frame 122 constituting the wearing section 120.

[0055] Therefore, in a wearable device 100 according to an embodiment of the present invention, since the weight of the main body 110 itself can be reduced by omitting the weight of the battery, even if the user wears the wearable device 100, the user's body can be prevented from leaning forward due to the weight of the main body 110. Furthermore, since the weight of the wearing part 120 itself increases due to the added weight of the battery, the overall weight of the wearable device 100 can be shared.

[0056] Furthermore, in a wearable device 100 according to an embodiment of the present invention, since the battery portions 130a and 130b are disposed on the wearing portion 120 side, the main body portion 110 does not require a separate space for the built-in battery. Therefore, the wearable device 100 according to an embodiment of the present invention can reduce the overall size of the main body portion 110, thus achieving miniaturization and thinning.

[0057] Furthermore, since the space for installing the battery in the main body 110 is omitted, the internal space of the main body 110 can be utilized while maintaining the same size. Therefore, the internal space of the main body 110 can also include other functional modules besides the aforementioned functional modules.

[0058] Furthermore, according to an embodiment of the present invention, the wearable device 100 can reduce the overall weight and achieve lightweighting by using a flexible battery with a relatively light unit energy storage weight instead of a prismatic battery with a relatively heavy unit energy storage weight as a power source.

[0059] In this configuration, battery units 130a and 130b can be composed of a single flexible battery; however, they can also be composed of multiple flexible batteries to increase the overall capacity. Furthermore, at least one flexible battery in battery units 130a and 130b can be detachably attached to the wearing part 120 so that it can continue to be used even if the battery power is depleted, through simple replacement.

[0060] As an example, the battery units 130a and 130b may include a first battery 130a that functions as a main battery and provides driving power to the main body 110 side, and a second battery 130b that functions as an auxiliary battery and assists the first battery 130a. The second battery 130b can be detachably combined with the wearing part 120, and can be easily separated from the wearing part 120 when the user operates it.

[0061] The first battery 130a and the second battery 130b can be configured as flexible batteries as described above, and the flexible battery can be a plate-shaped flexible battery with a predetermined area and length. Furthermore, the first battery 130a and the second battery 130b may each include separate circuit sections 152 and 153 for controlling charging / discharging or preventing overcharging. This flexible battery will be described in detail later.

[0062] Accordingly, when the power of the battery units 130a and 130b is partially or completely depleted, the user can easily replace the second battery 130b to provide driving power to the first battery 130a side. Thus, the main body 110 can be continuously driven.

[0063] For this purpose, the wearing portion 120 may include a receiving slot 123 for accommodating the second battery 130b, the second battery 130b being detachably coupled to the receiving slot 123. Furthermore, the wearable device 100 may include an operation portion 140 disposed on the wearing portion 120 so that the second battery 130b mounted in the receiving slot 123 can be easily detached from the receiving slot 123 during user operation.

[0064] As a non-restrictive example, such as Figure 2As shown, the second frame 122 may include a receiving groove 123 formed along the length direction, and the operating part 140 may be disposed on the second frame 122 so as to be located around the border defining the receiving groove 123.

[0065] Furthermore, the receiving groove 123 can be formed by recessing a predetermined depth from the upper surface of the second frame 122 to open the upper part, and the operation part 140 can be provided with a button for user operation on one surface of the second frame 122.

[0066] In this case, such as Figure 1 and Figure 2 As shown, the first battery 130a can be disposed on one surface of the first frame 121 along the length direction of the first frame 121, and the second battery 130b can be inserted into the receiving slot 123.

[0067] At this time, the first battery 130a can be disposed on one surface of the first frame 121 by means of a cover member 124 that is coupled to one surface of the first frame 121, and can be electrically connected to the main body 110.

[0068] Furthermore, the second battery 130b can be detachably attached to the receiving groove 123 while being attached to the support member 151.

[0069] The second battery 130b may be integrally formed with the support member 151, or may be detachably attached to one side of the support member 151.

[0070] Furthermore, the support member 151 may be formed of a rigid material to maintain a shape substantially similar to the receiving groove 123, or it may be formed of a flexible soft material.

[0071] Furthermore, the support member 151 can be electrically connected to the first battery 130a when inserted into the receiving groove 123. For this purpose, the support member 151 may include externally exposed connection terminals for electrical connection to the second battery 130b, and these connection terminals may contact corresponding connection terminals disposed inside the receiving groove 123. As an example, either the connection terminal or the corresponding connection terminal may be a known spring pin.

[0072] Therefore, the first battery 130a can be prevented from being exposed to the outside by the cover member 124, and can function as a main battery to provide driving power to the main body 110 while being fixed to one side of the first frame 121.

[0073] Furthermore, the second battery 130b can be electrically connected to the first battery 130a to provide power to the first battery 130a when it is installed in the receiving slot 123 via the support member 151. Thus, the second battery 130b can function as an auxiliary battery to supplement the capacity of the first battery 130a, and when its stored power is partially or completely depleted, it can be detached from the receiving slot 123 and replaced with a new second battery 130b.

[0074] That is, such as Figure 3 and Figure 4 As shown, when it is necessary to replace the second battery 130b installed in the receiving slot 123, when the user operates the operating part 140, the second battery 130b can move upward from the receiving slot 123 and protrude outward by at least a portion of its length while connected to the support member 151.

[0075] Therefore, in a wearable device 100 according to an embodiment of the present invention, the second battery 130b, detachably coupled to the receiving slot 123, can function as an auxiliary battery to supply power to the first battery 130a. Accordingly, even if the power of the first battery 130a and the second battery 130b is completely depleted, the wearable device 100 according to an embodiment of the present invention can continue to supply power to the first battery 130a by replacing the second battery 130b.

[0076] Therefore, the wearable device 100 according to an embodiment of the present invention can be continuously powered by replacing the second battery 130b, thereby extending the usage time or enabling continuous use.

[0077] The second battery 130b can supply the stored power to the first battery 130a side, but when the power of the first battery 130a is completely depleted, it can also supply the stored power to the main body 110 side.

[0078] On the other hand, as described above, the first battery 130a and the second battery 130b can be configured as flexible batteries, and the flexible battery can be in the form of a plate with a predetermined area and length and flexibility.

[0079] Therefore, even if the first battery 130a and the second battery 130b are respectively attached to the first frame 121 and the second frame 122 which are formed in an arc shape, the first battery 130a and the second battery 130b can be transformed into shapes corresponding to the first frame 121 and the second frame 122.

[0080] Specifically, such as Figure 2As shown, the first battery 130a and the second battery 130b can be connected to the first frame 121 and the second frame 122 respectively in a bent state.

[0081] like Figures 5 to 7 As shown, the first battery 130a and the second battery 130b may have an electrode assembly 131 sealed together with the electrolyte inside the outer materials 137 and 138.

[0082] At this time, the first battery 130a and the second battery 130b may respectively include patterns 136 and 139 formed along the length directions of the electrode assembly 131 and the external materials 137 and 138, and the first pattern 136 formed on the electrode assembly 131 and the second pattern 139 formed on the external materials 137 and 138 may be configured to have the same orientation.

[0083] Therefore, as Figures 1 to 4 As shown, even if the first battery 130a and the second battery 130b are mounted in a bent state on one side of the wearing part 120, the first battery 130a and the second battery 130b can prevent or minimize the deformation of the substrate itself constituting the electrode assembly 131 and the external materials 137 and 138 through the patterns 136 and 139.

[0084] Therefore, even if the first battery 130a and the second battery 130b are installed in a bent state, the deformation of the substrate itself that may occur in the bent portion can be minimized, thus preventing the first battery 130a and the second battery 130b from being damaged or degraded in performance due to the bending of the electrode assembly 131 and the external materials 137 and 138.

[0085] Here, the first pattern 136 and the second pattern 139 not only have the same orientation, but can also be formed on the electrode assembly 131 and the external materials 137 and 138 respectively to overlap with each other. This is to ensure that the first pattern 136 and the second pattern 139 always perform the same behavior.

[0086] As described above, in the first battery 130a and the second battery 130b applied to the present invention, the patterns 136 and 139 formed on the electrode assembly 131 and the external materials 137 and 138 respectively are formed to overlap each other so as to contract and relax in the length direction. Therefore, even if bending occurs in the length direction, the electrode assembly 131 and the external materials 137 and 138 can always maintain a uniform spacing or contact state relative to the total length.

[0087] Therefore, even if the first battery 130a and the second battery 130b are mounted in a bent state on the first frame 121 and the second frame 122 respectively, the performance of the battery can be prevented from degrading because the electrolyte sealed together with the electrode assembly 131 can be evenly distributed along the entire length.

[0088] As an example, such as Figure 6 As shown in portions (a) to (d), the peaks and valleys of each of the first pattern 136 and the second pattern 139 may be formed in a direction parallel to the width direction of the electrode assembly 131 and the external materials 137 and 138, and the peaks and valleys may be alternately arranged along the length direction of the electrode assembly 131 and the external materials 137 and 138.

[0089] Furthermore, the peaks and valleys constituting the first pattern 136 and the second pattern 139 can be formed such that the peaks are formed in the same position and the valleys are formed in the same position. Therefore, the first pattern 136 and the second pattern 139 can overlap each other.

[0090] Specifically, the peaks and valleys of the first pattern 136 and the second pattern 139 can be formed along a straight line parallel to the width direction of the electrode assembly 131 and the external materials 137 and 138, and can be formed such that the peaks and valleys are repeated along the length direction.

[0091] Here, the patterns 136 and 139 may be formed continuously along a direction parallel to the width direction of the electrode assembly 131 and the external materials 137 and 138, or they may be formed discontinuously. Furthermore, the patterns 136 and 139 may be formed over the entire length of the electrode assembly 131 and the external materials 137 and 138, or they may be formed partially over a portion of the length.

[0092] Furthermore, the peaks and valleys can be configured with various cross-sections, such as semi-circular arc-shaped cross-sections, polygonal cross-sections including triangles or squares, and cross-sections combining arc-shaped and polygonal cross-sections. Additionally, each of the peaks and valleys can be configured to have the same spacing and width, or it can be configured to have different spacing and widths.

[0093] Therefore, even though the electrode assembly 131 and the external materials 137 and 138 are built into one side of the wearing part 120 in a bent state, the first battery 130a and the second battery 130b can reduce the fatigue applied to the substrate itself through the patterns 136 and 139, thereby preventing damage or battery performance degradation.

[0094] On the other hand, the first pattern 136 and the second pattern 139 can be formed such that the spacing between adjacent peaks or the spacing between valleys is the same, or they can be set to have different spacings, or they can be formed into a shape that combines the same spacing and different spacings.

[0095] The electrode assembly 131 can be sealed together with the electrolyte inside the external materials 137 and 138. For example... Figure 7 As shown, this electrode assembly 131 may include a positive electrode 132, a negative electrode 134, and a separation membrane 133.

[0096] The positive electrode 132 may include a positive current collector 132a and a positive active material 132b, and the negative electrode 134 may include a negative current collector 134a and a negative active material 134b. The positive current collector 132a and the negative current collector 134a may be implemented as plate-shaped sheets with a predetermined area.

[0097] That is, the active materials 132b and 134b can be compressed, deposited, or coated on one or both surfaces of the current collectors 132a and 134a of the positive electrode 132 and negative electrode 134, respectively. In this case, the active materials 132b and 134b can be disposed over the entire area of ​​the current collectors 132a and 134a, or they can be disposed in a portion of the current collectors 132a and 134a.

[0098] Furthermore, the positive current collector 132a and the negative current collector 134a may each include a negative terminal 135a and a positive terminal 135b for electrical connection with an external device.

[0099] The positive terminal 135b and the negative terminal 135a can be provided in a form that protrudes from one side of the external materials 137 and 138 by extending a predetermined length from the positive current collector 132a and the negative current collector 134a, and can be provided to be exposed on the surface of the external materials 137 and 138.

[0100] In this case, the positive electrode active material 132b and the negative electrode active material 134b may contain polytetrafluoroethylene (PTFE). Therefore, even if the first battery 130a and the second battery 130b are bent, it is possible to prevent the positive electrode active material 132b and the negative electrode active material 134b from separating from their respective current collectors 132a and 134a or from developing cracks due to bending.

[0101] On the other hand, the separation membrane 133 disposed between the positive electrode 132 and the negative electrode 134 may include a nanofiber web layer 151b on one or both sides of the nonwoven fabric layer 151a.

[0102] The nanofiber mesh layer 151b may be a nanofiber comprising at least one selected from polyacrylonitrile nanofibers and polyvinylidene fluoride nanofibers.

[0103] The external materials 137 and 138 may be formed of plate-shaped members having a predetermined area, and may protect the electrode assembly 131 from external forces by accommodating the electrode assembly 131 and the electrolyte therein.

[0104] As an example, the outer materials 137 and 138 may comprise a pair of first outer materials 137 and second outer materials 138, the adjacent frame sides of which may be sealed with an adhesive. This prevents the electrolyte and electrode assembly 131 housed within the outer materials 137 and 138 from being exposed to the outside, and also prevents the electrolyte from leaking to the outside.

[0105] These outer materials 137 and 138 are composed of the first outer material 137 and the second outer material 138, and all the edge sides of the first outer material 137 and the second outer material 138 constituting the sealing portion can be sealed with adhesive. Alternatively, the first outer material 137 and the second outer material 138 can be constructed as a single component and can be folded in either the width or length direction, and the remaining edge portions of the first outer material 137 and the second outer material 138 that meet each other can be sealed with adhesive.

[0106] On the other hand, the wearable device 100 according to the present invention can also be in the form of having both augmented reality and virtual reality functions, or it can be in the form of integrating augmented reality and virtual reality functions, and can display information synchronized with a smartphone through the display unit 112.

[0107] Furthermore, when the wearable device 100 according to the present invention is implemented as a virtual reality device, a smartphone with virtual reality functionality can be detachably attached to the main body 110.
