Pursuant to 35 U.S.C. §119(a), this application claims the benefit of earlier filing date and right of priority to Korean Application No. 10-2014-0030484, filed in filed in the Republic of Korea on Mar. 14, 2014, and Korean Application No. 10-2014-0184909, filed in the Republic of Korea on Dec. 19, 2014, the contents of which are expressly incorporated by reference herein in their entireties.
BACKGROUND OF THE INVENTION
Field of the Invention
The present disclosure relates to an optical device that can be detachably attached to a glass type terminal.
Description of Related Art
Terminals may be generally classified as mobile/portable terminals or stationary terminals according to their mobility. Mobile terminals may also be classified as handheld terminals or vehicle mounted terminals according to whether or not a user can directly carry the terminal.
Mobile terminals have become increasingly more functional. Examples of such functions include data and voice communications, capturing images and video via a camera, recording audio, playing music files via a speaker system, and displaying images and video on a display. Efforts are ongoing to support and increase the functionality of mobile terminals. Such efforts include software and hardware improvements, as well as changes and improvements in the structural components.
Recently, a wearable type mobile terminal configured to be worn on a human being's body has been developed. A wearable terminal has a particular structure to be fixed to part of a user's body. For example, a glass type terminal essentially has such a structure that it is worn on both ears and a head. Also, the promotion of functions of the mobile terminal trades off degradation of a design diversity and aesthetic sense.
Also, due to the structural characteristics of glass type terminals to be worn on a human body, there is a limitation in provided power and it is difficult to utilize stored data.
BRIEF SUMMARY OF THE INVENTION
Therefore, an aspect of the detailed description is to provide a mobile terminal which can be detachably attached to a glass type terminal.
To achieve these and other advantages and in accordance with the purpose of this specification, as embodied and broadly described herein, an optical device in a glass type terminal configured to be detachably attached to a frame fixed to a user's head part, wherein the optical device includes a body unit extending in one direction, a display unit extending in a direction intersecting the one direction, connected to one end of the body unit, and disposed to be adjacent to the user's eyes when the display unit is fixed to the frame, so as to provide visual information, and a clip unit protruding from the body unit and caught by one region of the frame.
In an example related to the present disclosure, the clip unit may include: a fixing portion fixed to be movable in the body unit; and a hooked portion extending from the fixing portion and bent again so as to be caught by the frame. The clip unit may be fixed to various regions of various types of frames by the movable hooked portion, and the display unit may be adjusted to be adjacent to one of both eyes of the user.
To achieve these and other advantages and in accordance with the purpose of this specification, as embodied and broadly described herein, a terminal system may include an optical device including a clip unit detachably attached to a frame fixed to a user's body; an external device including a receiving unit configured such that the optical device separated from the frame is installed therein; and a control unit configured to control to transmit and receive signal from the optical device and the external device.
In an example related to the present disclosure, the external device may further include a display unit configured to output visual data, wherein when the optical device is installed in the receiving unit, the control unit may control the display unit to transmit data from the optical device to the external device and output screen information including the data. Accordingly, data collected from the optical device and data regarding a driving log may be easily checked.
In an example related to the present disclosure, the glass type terminal may include a clip module configured to electrically connect the optical device to the frame, and the clip module may include an assembling protrusion protruding from the body unit; an assembling recess formed in the frame to allow the assembling protrusion to be inserted therein; and a connection terminal unit disposed to be adjacent to the assembling protrusion and the assembling recess.
Thus, by electrically connecting the glass type terminal including a frame and the optical device, desired may be transmitted and received between the glass type terminal and the optical device, and any other device which is electrically connected to the glass type terminal and the optical device can be controlled.
According to an exemplary embodiment of the present disclosure, by using the assembling protrusion and the assembling recess connecting the frame and the body unit of the glass type terminal, the optical device can be brought into contact with the optical device. Also, assembling may be strengthened by using an elastic member, and stable contact may be implemented.
Also, since a circuit board of the optical device is disposed within a hinge unit for rotating the body unit, damage due to exposure of the circuit board may be prevented.
Also, the optical device may be installed in a frame of glasses by the clip module, regardless of type of glasses. Also, since a region of the clip module in which the frame is inserted is formed to be adjustable, the optical device may be stably installed in the frame, or the like.
Also, the optical device may be installed in a pouch, a mobile terminal, or a case of a mobile terminal, and the like, so as to be charged, and data collected from the optical device may be output to a display unit formed as a display panel, or the like, to allow the user to check a driving log of the optical device more conveniently.
Further scope of applicability of the present application will become more apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from the detailed description.

In some cases, the optical device 600 may perform assorted control functions associated with a connected external device, in response to the external device being connected to the interface unit 660.
The memory 670 is typically implemented to store data to support various functions or features of the optical device 600. For instance, the memory 670 may be configured to store application programs executed in the optical device 600, data or instructions for operations of the optical device 600, and the like. Some of these application programs may be downloaded from an external server via wireless communication. Other application programs may be installed within the optical device 600 at time of manufacturing or shipping, which is typically the case for basic functions of the optical device 600 (for example, receiving a call, placing a call, receiving a message, sending a message, and the like). It is common for application programs to be stored in the memory 670, installed in the optical device 600, and executed by the control unit 680 to perform an operation (or function) for the optical device 600.
The control unit 680 typically functions to control overall operation of the optical device 600, in addition to the operations associated with the application programs. The control unit 680 may provide or process information or functions appropriate for a user by processing signals, data, information and the like, which are input or output by the various components depicted in FIG. 1, or activating application programs stored in the memory 670. As one example, the control unit 680 controls some or all of the components illustrated in FIG. 1 according to the execution of an application program that have been stored in the memory 670.
The power supply unit 690 can be configured to receive external power or provide internal power in order to supply appropriate power required for operating elements and components included in the optical device 600. The power supply unit 690 may include a battery, and the battery may be configured to be embedded in the terminal body, or configured to be detachable from the terminal body.
At least some of the above components may operate in a cooperating manner, so as to implement an operation or a control method of a glass type terminal according to various embodiments to be explained later. The operation or the control method of the glass type terminal may be implemented on the glass type terminal by driving at least one application program stored in the memory 670.
Referring still to FIG. 1, various components depicted in this figure will now be described in more detail.
Regarding the wireless communication unit 610, the broadcast receiving module 611 is typically configured to receive a broadcast signal and/or broadcast associated information from an external broadcast managing entity via a broadcast channel. The broadcast channel may include a satellite channel, a terrestrial channel, or both. In some embodiments, two or more broadcast receiving modules 611 may be utilized to facilitate simultaneously receiving of two or more broadcast channels, or to support switching among broadcast channels.
The mobile communication module 612 can transmit and/or receive wireless signals to and from one or more network entities. Typical examples of a network entity include a base station, an external mobile terminal, a server, and the like. Such network entities form part of a mobile communication network, which is constructed according to technical standards or communication methods for mobile communications (for example, Global System for Mobile Communication (GSM), Code Division Multi Access (CDMA), CDMA2000 (Code Division Multi Access 2000), EV-DO (Enhanced Voice-Data Optimized or Enhanced Voice-Data Only), Wideband CDMA (WCDMA), High Speed Downlink Packet access (HSDPA), HSUPA (High Speed Uplink Packet Access), Long Term Evolution (LTE), LTE-A (Long Term Evolution-Advanced), and the like).
Examples of wireless signals transmitted and/or received via the mobile communication module 612 include audio call signals, video (telephony) call signals, or various formats of data to support communication of text and multimedia messages.
The wireless Internet module 613 is configured to facilitate wireless Internet access. This module may be internally or externally coupled to the optical device 600. The wireless Internet module 613 may transmit and/or receive wireless signals via communication networks according to wireless Internet technologies.
Examples of such wireless Internet access include Wireless LAN (WLAN), Wireless Fidelity (Wi-Fi), Wi-Fi Direct, Digital Living Network Alliance (DLNA), Wireless Broadband (WiBro), Worldwide Interoperability for Microwave Access (WiMAX), High Speed Downlink Packet Access (HSDPA), HSUPA (High Speed Uplink Packet Access), Long Term Evolution (LTE), LTE-A (Long Term Evolution-Advanced), and the like. The wireless Internet module 613 may transmit/receive data according to one or more of such wireless Internet technologies, and other Internet technologies as well.
In some embodiments, when the wireless Internet access is implemented according to, for example, WiBro, HSDPA, HSUPA, GSM, CDMA, WCDMA, LTE, LTE-A and the like, as part of a mobile communication network, the wireless Internet module 613 performs such wireless Internet access. As such, the Internet module 613 may cooperate with, or function as, the mobile communication module 612.
The short-range communication module 614 is configured to facilitate short-range communications. Suitable technologies for implementing such short-range communications include BLUETOOTHTM, Radio Frequency IDentification (RFID), Infrared Data Association (IrDA), Ultra-WideBand (UWB), ZigBee, Near Field Communication (NFC), Wireless-Fidelity (Wi-Fi), Wi-Fi Direct, Wireless USB (Wireless Universal Serial Bus), and the like. The short-range communication module 614 in general supports wireless communications between the optical device 600 and a wireless communication system, communications between the optical device 600 and another optical device 600, or communications between the mobile terminal and a network where another optical device 600 (or an external server) is located, via wireless area networks. One example of the wireless area networks is a wireless personal area networks.
In some embodiments, another mobile terminal (which may be configured similarly to optical device 600) may be a wearable device, for example, a smart watch, a smart glass or a head mounted display (HMD), which is able to exchange data with the optical device 600 (or otherwise cooperate with the optical device 600). The short-range communication module 614 may sense or recognize the wearable device, and permit communication between the wearable device and the optical device 600. In addition, when the sensed wearable device is a device which is authenticated to communicate with the optical device 600, the control unit 680, for example, may cause transmission of data processed in the optical device 600 to the wearable device via the short-range communication module 614. Hence, a user of the wearable device may use the data processed in the optical device 600 on the wearable device. For example, when a call is received in the optical device 600, the user may answer the call using the wearable device. Also, when a message is received in the optical device 600, the user can check the received message using the wearable device.
The location information module 615 is generally configured to detect, calculate, derive or otherwise identify a position of the mobile terminal. As an example, the location information module 615 includes a Global Position System (GPS) module, a Wi-Fi module, or both. If desired, the location information module 615 may alternatively or additionally function with any of the other modules of the wireless communication unit 610 to obtain data related to the position of the mobile terminal. As one example, when the mobile terminal uses a GPS module, a position of the mobile terminal may be acquired using a signal sent from a GPS satellite. As another example, when the mobile terminal uses the Wi-Fi module, a position of the mobile terminal can be acquired based on information related to a wireless access point (AP) which transmits or receives a wireless signal to or from the Wi-Fi module.
The input unit 620 may be configured to permit various types of input to the mobile terminal 620. Examples of such input include audio, image, video, data, and user input. Image and video input is often obtained using one or more cameras 621. Such cameras 621 may process image frames of still pictures or video obtained by image sensors in a video or image capture mode. The processed image frames can be displayed on the display unit 651 or stored in memory 670. In some cases, the cameras 621 may be arranged in a matrix configuration to permit a plurality of images having various angles or focal points to be input to the optical device 600. As another example, the cameras 621 may be located in a stereoscopic arrangement to acquire left and right images for implementing a stereoscopic image.
The user input unit 623 is a component that permits input by a user. Such user input may enable the control unit 680 to control operation of the optical device 600. The user input unit 623 may include one or more of a mechanical input element (for example, a key, a button located on a front and/or rear surface or a side surface of the optical device 600, a dome switch, a jog wheel, a jog switch, and the like), or a touch-sensitive input, among others. As one example, the touch-sensitive input may be a virtual key or a soft key, which is displayed on a touch screen through software processing, or a touch key which is located on the mobile terminal at a location that is other than the touch screen. On the other hand, the virtual key or the visual key may be displayed on the touch screen in various shapes, for example, graphic, text, icon, video, or a combination thereof.
A touch sensor can sense a touch applied to the touch screen, such as display unit 651, using any of a variety of touch methods. Examples of such touch methods include a resistive type, a capacitive type, an infrared type, and a magnetic field type, among others.
As one example, the touch sensor may be configured to convert changes of pressure applied to a specific part of the display unit 651, or convert capacitance occurring at a specific part of the display unit 651, into electric input signals. The touch sensor may also be configured to sense not only a touched position and a touched area, but also touch pressure and/or touch capacitance. A touch object is generally used to apply a touch input to the touch sensor. Examples of typical touch objects include a finger, a touch pen, a stylus pen, a pointer, or the like.
When a touch input is sensed by a touch sensor, corresponding signals may be transmitted to a touch controller. The touch controller may process the received signals, and then transmit corresponding data to the control unit 680. Accordingly, the control unit 680 may sense which region of the display unit 651 has been touched. Here, the touch controller may be a component separate from the control unit 680, the control unit 680, and combinations thereof.
In some embodiments, the control unit 680 may execute the same or different controls according to a type of touch object that touches the touch screen or a touch key provided in addition to the touch screen. Whether to execute the same or different control according to the object which provides a touch input may be decided based on a current operating state of the optical device 600 or a currently executed application program, for example.
The touch sensor and the proximity sensor may be implemented individually, or in combination, to sense various types of touches. Such touches includes a short (or tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swipe touch, a hovering touch, and the like.
If desired, an ultrasonic sensor may be implemented to recognize position information relating to a touch object using ultrasonic waves. The control unit 680, for example, may calculate a position of a wave generation source based on information sensed by an illumination sensor and a plurality of ultrasonic sensors. Since light is much faster than ultrasonic waves, the time for which the light reaches the optical sensor is much shorter than the time for which the ultrasonic wave reaches the ultrasonic sensor. The position of the wave generation source may be calculated using this fact. For instance, the position of the wave generation source may be calculated using the time difference from the time that the ultrasonic wave reaches the sensor based on the light as a reference signal.
The camera 621 typically includes at least one a camera sensor (CCD, CMOS etc.), a photo sensor (or image sensors), and a laser sensor.
Implementing the camera 621 with a laser sensor may allow detection of a touch of a physical object with respect to a 3D stereoscopic image. The photo sensor may be laminated on, or overlapped with, the display device. The photo sensor may be configured to scan movement of the physical object in proximity to the touch screen. In more detail, the photo sensor may include photo diodes and transistors at rows and columns to scan content received at the photo sensor using an electrical signal which changes according to the quantity of applied light. Namely, the photo sensor may calculate the coordinates of the physical object according to variation of light to thus obtain position information of the physical object.
The display unit 651 is generally configured to output information processed in the optical device 600. For example, the display unit 651 may display execution screen information of an application program executing at the optical device 600 or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information.
In some embodiments, the display unit 651 may be implemented as a stereoscopic display unit for displaying stereoscopic images.
A typical stereoscopic display unit may employ a stereoscopic display scheme such as a stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme (glassless scheme), a projection scheme (holographic scheme), or the like.
The audio output module 652 is generally configured to output audio data. Such audio data may be obtained from any of a number of different sources, such that the audio data may be received from the wireless communication unit 610 or may have been stored in the memory 670. The audio data may be output during modes such as a signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. The audio output module 652 can provide audible output related to a particular function (e.g., a call signal reception sound, a message reception sound, etc.) performed by the optical device 600. The audio output module 652 may also be implemented as a receiver, a speaker, a buzzer, or the like.
A haptic module 653 can be configured to generate various tactile effects that a user feels, perceive, or otherwise experience. A typical example of a tactile effect generated by the haptic module 653 is vibration. The strength, pattern and the like of the vibration generated by the haptic module 653 can be controlled by user selection or setting by the control unit. For example, the haptic module 653 may output different vibrations in a combining manner or a sequential manner.
Besides vibration, the haptic module 653 can generate various other tactile effects, including an effect by stimulation such as a pin arrangement vertically moving to contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a touch to the skin, a contact of an electrode, electrostatic force, an effect by reproducing the sense of cold and warmth using an element that can absorb or generate heat, and the like.
The haptic module 653 can also be implemented to allow the user to feel a tactile effect through a muscle sensation such as the user's fingers or arm, as well as transferring the tactile effect through direct contact. Two or more haptic modules 653 may be provided according to the particular configuration of the optical device 600.
An optical output module 654 can output a signal for indicating an event generation using light of a light source. Examples of events generated in the optical device 600 may include message reception, call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like.
A signal output by the optical output module 654 may be implemented in such a manner that the mobile terminal emits monochromatic light or light with a plurality of colors. The signal output may be terminated as the mobile terminal senses that a user has checked the generated event, for example.
The interface unit 660 serves as an interface for external devices to be connected with the optical device 600. For example, the interface unit 660 can receive data transmitted from an external device, receive power to transfer to elements and components within the optical device 600, or transmit internal data of the optical device 600 to such external device. The interface unit 660 may include wired or wireless headset ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, or the like.
The identification module may be a chip that stores various information for authenticating authority of using the optical device 600 and may include a user identity module (UIM), a subscriber identity module (SIM), a universal subscriber identity module (USIM), and the like. In addition, the device having the identification module (also referred to herein as an “identifying device”) may take the form of a smart card. Accordingly, the identifying device can be connected with the terminal 100 via the interface unit 660.
When the optical device 600 is connected with an external cradle, the interface unit 660 can serve as a passage to allow power from the cradle to be supplied to the optical device 600 or may serve as a passage to allow various command signals input by the user from the cradle to be transferred to the mobile terminal there through. Various command signals or power input from the cradle may operate as signals for recognizing that the mobile terminal is properly mounted on the cradle.
The memory 670 can store programs to support operations of the control unit 680 and store input/output data (for example, phonebook, messages, still images, videos, etc.). The memory 670 may store data related to various patterns of vibrations and audio which are output in response to touch inputs on the touch screen.
The memory 670 may include one or more types of storage mediums including a Flash memory, a hard disk, a solid state disk, a silicon disk, a multimedia card micro type, a card-type memory (e.g., SD or DX memory, etc), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a Read-Only Memory (ROM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a Programmable Read-Only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. The optical device 600 may also be operated in relation to a network storage device that performs the storage function of the memory 670 over a network, such as the Internet.
The control unit 680 may typically control the general operations of the optical device 600. For example, the control unit 680 may set or release a lock state for restricting a user from inputting a control command with respect to applications when a status of the mobile terminal meets a preset condition.
The control unit 680 can also perform the controlling and processing associated with voice calls, data communications, video calls, and the like, or perform pattern recognition processing to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images, respectively.

FIG. 2 is a view illustrating an optical device according to an exemplary embodiment of the present disclosure viewed in one direction, and FIG. 3 is a conceptual view illustrating a state in which the optical device is installed in a frame to be fixed to a user's body.
Referring to FIGS. 2 and 3, the optical device 600 includes a main body including a first body 601 and a second body 602, a display unit 651, a user input unit 623, a camera 621, and a clip module 700.
The first body 601 extends in one direction D1, and the second body 602 extends in a second direction D2 crossing the first direction D1, and thus, the first body 601 and the second body 602 have a bar shape. An angle between the first direction D1 and the second direction D2 may be an obtuse angle, but the present disclosure is not limited thereto.
The display unit 651 is disposed in the second body 602, and the user input unit 623 may be disposed in the first body 601. The clip module 700 is fixed to the glass type terminal 400.
The display unit 651 may be realized as a head mounted display (HMD). Here, HMD refers to a display mounted on a head part to directly show the user an image. In a case in which the optical device 600 is mounted on the user's head part, the display unit 651 may be fixed to the glass type terminal 400 and correspond to at least one of a left eye and a right eye so as to directly provide an image in front of user's eyes.
The display unit 651 may project an image to the user's eyes by using a prism. Also, the prism may be formed to be light-transmissive such that the user may view the projected image and a front general visual field (i.e., a range within which objects are visible to the user's eyes).
Thus, the image output through the display unit 651 may be overlap with a general visual field so as to be shown. The optical device 600 may provide an augmented reality (AR) in which a virtual image overlaps on a real image or a background to show a single image by using the characteristics of the display. That is, the display unit 651 may be implemented according to at least one methods among LCOS, LCD, OLED, and T-OLED.
The camera 621 may obtain a scene that the user is viewing, as an image. The optical device 600 may include a plurality of cameras 621 to obtain a stereoscopic image.
The optical device 600 may further include an audio output unit 452 and a battery 490.
The user input unit 623 is formed to receive a control command from the optical device 600. The user input unit 623 may employ any tactile method that allows the user to perform manipulation such as touch, push, scroll, or the like.
An outer surface of the first body 601 in which the user input unit 623 is formed may have a curved surface, but the present disclosure is not limited thereto. Although not shown in detail in the drawings, the user input unit 623 may sense a user's touch input continuously applied in the first direction D1 and generate a control command.
The audio output module 652 may be formed in the other end portion of the first body 601. The audio output module 652 may be configured to produce audio in a general audio output manner or an osteoconductive manner. The audio output module 652 may be formed on the first body 601 so as to be adjacent to the user's ears. When the audio output module 652 is implemented in the osteoconductive manner, the audio output module 652 may be closely adhered to the head when the user wears the optical device 600 and vibrate the user's skull to transfer sounds.
The optical device 600 includes a circuit board 681 (see FIG. 4B). The circuit board 681 may be configured to control various electronic components provided in the optical device 600.
Also, the optical device 600 may further include a microphone receiving a sound and processing the received sound to electrical voice data.
Referring to FIG. 3, the optical device 600 fixed to the first frame 401 by the clip module 700. When the optical device 600 is fixed to the first frame 401 and the glass type terminal 400 is fixed to the user's head part, the display unit 651 may be disposed in front of the user's eyes.
However, the glass type terminal 400 to which the optical device 600 is fixed is not limited to a terminal and any glasses which are used to correct vision or which performs a general function to prevent incidence of light to eyes may be used as the first frame 401. Thus, the optical device 600 does not require a separate fixing device allowing the optical device 600 to be disposed in a region adjacent to the users' eyes. Also, the user may install the optical device 600 to glasses when necessary or may remove the optical device 600 from the glasses when not necessary, through the clip module 700.
However, the first frame 401 may correspond to a glass type fixing structure which is separately manufactured. In this case, in the first frame 401, the glass structure covering the user's eyes may be omitted and the lens may be formed of glass without power.
The optical device 600 may be installed in the user's glasses, or the like, so as to be fixed to the user's body. Thus, the user does not require a separate fixing structure to be additionally installed in his or her body, and when the optical device 600 is not necessary, the user may remove the optical device 600 by using the clip module 700.
When the glass type terminal 400 is changed, the optical device 600 may be deformed in a state of being fixed to the glass type terminal 400. Hereinafter, a driving state of the glass type terminal 400 to which the optical device 600 is fixed will be described. FIGS. 4A and 4B are conceptual views illustrating a driving structure of the glass type terminal to which an optical device is fixed.
The glass type terminal 400 includes a first frame 401 and a second frame 402 extending with a lens 403 interposed therebetween. The first frame 401 and the second frame 402 are spread or folded at a particular angle with respect to the lens 403.
When the first body 601 is fixed to the first frame 401, the second body 602 bent from the first body 601 is disposed on the lens 403. An angle between the first frame 401 and the second frame 402 and the lens 403 is changed according to a usage state of the user. For example, the lens 403 may extend in the second direction and the first frame 401 is oriented in the first direction D1, and in this state, the first frame 401 may be changed to extend in a third direction D3 crossing the first and second directions D1 and D2.
Also, the first frame 401 and the second frame 402 may be changed to be folded so as to overlap with the lens 403 in the second direction D2.
An angle between the first body 601 and the second body 602 is changed according to a change in a state of the first frame 401. Referring to FIG. 4B, the first body 601 and the second body 602 are connected by a hinge unit 603 formed to be rotatable by an external force. The first body 601 and the second body 602 relatively rotate with respect to the hinge unit 603, and the hinge unit 603 is disposed such that a region thereof is exposed. A hinge shaft is formed in the center of the hinge unit 603.
Meanwhile, the first body 601 and the second body 602 include a circuit board 681 for transmitting an electrical signal. The circuit board 681 connects the first body 601 and the second body 602 and electrically connects an electronic component. The circuit board 681 is formed as a flexible circuit board that may be pliable according to a rotation between the first body 601 and the second body 602.
A receiving space is formed within the hinge unit 603 in order to receive the circuit board 681. The receiving space may be formed along the hinge shaft. An internal space is formed within the first body 601 and the second body 602 in order to receive the circuit board 681. Since the circuit board 681 is disposed in the receiving space, even though the first body 601 and the second body 602 relatively rotate, the circuit board 681 is not exposed outwardly.
Referring to FIG. 4B, when the angle between the first body 601 and the second body 602 is reduced, the spread circuit board 681 is folded in the internal space of the first body 601 and the second body 602 so as to be received therein. Accordingly, the circuit board 681 is inserted inside, rather than being exposed, and thus, damage thereto can be prevented.
The clip type mobile terminal according to an exemplary embodiment of the present disclosure may be electrically connected to the glass type terminal 400 installed on the user's head part, and separably fixed thereto. Hereinafter, the optical device 600 according to various exemplary embodiments of the present disclosure will be described.
FIGS. 5A(a) and 5A(b) are views illustrating a clip module according to an exemplary embodiment of the present disclosure. Specifically, FIG. 5A(a) is a partial enlarged view of the optical device illustrating a clip module according to an exemplary embodiment of the present disclosure, and FIG. 5A(b) is a partial cross-sectional view of the optical device taken along line A-A.
Referring to FIGS. 5A(a) and 5A(b), the clip module 700 is formed to be caught by (or hung up on) the first frame 401. The clip module 700 protrudes from one surface of the first body 601. For example, the clip module 700 protrudes from an inner surface of the first body 601 in a direction intersecting the first direction D1.
For example, the clip module 700 includes a hooked portion 701a formed to have a structure bent at a preset angle (e.g., about 90 degrees). In order to minimize separation of the first frame 401 from the clip module 700, the preset angle may be an acute angle. One cross-section of the hooked portion 701a may have an “L” shape. A portion of the first frame 401 is inserted in a space between the hooked portion 701a and one cross-section of the first body 601.
Meanwhile, the clip module 700 may extend in the first direction D1. Alternatively, the clip module 700 may include a plurality of protrusion members spaced apart from one another by a preset interval.
Referring to FIG. 5A(a), the clip module 700 is formed to be movable on the first body 601. In a case in which the third direction D3 perpendicular to the first direction D1 is defined as a thickness direction of the first body 601, the clip module 700 is formed to reciprocate in the third direction D3 as the user applies force thereto. Namely, the clip module 700 is formed such that one region thereof is inserted into the interior of the first body 601 and protrudes to the outside of the first body 601.
Referring to FIG. 5A(b), the first body 601 includes a hole 601′ formed to corresponding to a length of the clip module 700. Also, the first body 601 may have an internal space communicating with the hole 601′.
A portion of the clip module 700 passes through the hole 601′ so as to be positioned in the internal space. The clip module 700 is positioned in the internal space, and in order to prevent separation of the clip module 700 from the hole 601′, the clip module 700 includes a first fixing portion 702. Thus, even when the user applies pressure, separation of the clip module 700 from the first body 601 may be prevented.
By external pressure applied to the hooked portion 701a, the hooked portion 701a passes through the hole 601′ and moves in the third direction D3.
The clip module 700 may further include an elastic member providing elastic force to allow the hooked portion 701a to be moved to the interior of the first body 601. Accordingly, the user may pull the hooked portion 701a from the first body 601 to form a space and insert the frame.
Alternatively, the hooked portion 701a may be inserted between an outer surface of the hooked portion 701a passing through the hole 601′ and an inner circumferential surface (or an outer surface of the body unit).
For example, a protrusion, a recess, a spiral structure, and the like, generating frictional contact may be formed on the outer circumferential surface of the hooked portion 701a or the outer circumferential surface of the hole 601′. Accordingly, the user may insert the frame between the first body 601 and the hooked portion 701a and move the hooked portion 701a to more stably fix the frame to the clip module 700.
In this case, the hooked portion 701a and one surface of the first body 601 may be integrally formed.
According to the present exemplary embodiment, a width of the space between the first body 601 and the hooked portion 701a may be adjusted, and frames having various thicknesses may be inserted into the space. That is, the optical device may be applied to glasses having various types of frames.
Also, in a state in which the hooked portion 701a is caught on the first frame 401, the optical device 600 may be more stably fixed to the first frame 401 by adjusting the space between the hooked portion 701a and the first body 601.
FIGS. 5B(a) and 5B(b) are conceptual views illustrating an optical device according to another exemplary embodiment of the present disclosure. Specifically, FIG. 5B(a) is a partial exploded view illustrating a push key 424 included in the optical device 600 according to another exemplary embodiment of the present disclosure, and FIG. 5B(b) is a conceptual view illustrating a control method of outputting notification information according to the push key 424.
Referring to FIG. 5B(a), an optical device 600 according to the present exemplary embodiment has the push key 424 formed on one surface of the first body 601 on which the hooked portion 701b is formed. The push key 424 is deformed by an external force applied from the outside and generates a signal.
The push key 424 may be formed to overlap with the hooked portion 701b. When the push key 424 is not pressed, the control unit controls the display unit 651 to output first notification information 11. For example, the first notification information 11 may correspond to light having a preset color or may correspond to a particular icon, or the like.
Meanwhile, when the push key 424 is pressed by an external force, the control unit controls the display unit 651 to limit output of the first notification information 11. In a case in which the first frame 401 is inserted between the hooked portion 701b and the first body 601 and the first frame 401 presses the push key 424 by a force applied between the hooked portion 701b and the first body 601, output of the first notification information 11 is limited.
That is, when the first frame 401 is not stably fixed by the hooked portion 701b, corresponding information is provided to the user by the first notification information 11 on the display unit 651. Also, when the first frame 401, the first body 601, and the hooked portion 701b are tightly attached according to a movement of the hooked portion 701b, it is determined that the hooked portion is stably installed on the first frame 401, and output of the first notification information 11 is limited.
According to the present exemplary embodiment, the user may install the optical device in glasses, or the like, and used in a more stable state.
FIGS. 6A(a) and 6A(b) are views illustrating a clip module according to another exemplary embodiment of the present disclosure. Referring to FIGS. 6A(a) and 6A(b), a clip module 702 includes a hooked portion 702a and a second fixing portion 702b extending from the hooked portion 702a. The second fixing portion 702b is formed to overlap with one surface of the first body 601. The second fixing portion 702b may be integrally formed with the hooked portion 702a at a preset angle. The preset angle may be about 90 degrees. That is, cross-sections of the hooked portion 702a and the second fixing portion 702b may have a channel shape (“” shape).
Referring to FIGS. 6A(a) and 6A(b), the clip module 702 may further include a fastening pin 702c formed on the second fixing portion 702b. The fastening pin 702 is fixed to a fastening hole formed in the first body 601 by passing through one region of the second fixing portion 702b. That is, the clip module 702 is formed to be rotatable with respect to the fastening pin 702c in a state of being connected to the first body 601.
By rotation of the clip module 702, the first body 601 may be fixed to one region of the first frame 401. For example, in a case in which the first frame 401 includes a pair of leg portions hung on both ears, it may be implemented such that the hooked portion 702a is hung on one leg portion among the pair of leg portions by rotation of the clip module 702.
Accordingly, the user may install the clip module 702 in one of both leg portions such that the display unit is disposed to be close to one eye.
FIGS. 6B(a) and 6B(b) are views illustrating a clip module according to another exemplary embodiment of the present disclosure. A clip module 703 according to the present exemplary embodiment includes a hooked portion 703a and a support portion 702b extending from the hooked portion 703a. Other components of the clip module 703, excluding the support portion 702b, are substantially the same as those of the clip module 700 of FIG. 5A(a), and thus, redundant descriptions thereof will be omitted.
Referring to FIGS. 6B(a) and 6B(b), the hooked portion 703a includes a first surface 703c and a second surface 703d. The first surface 703c and the second surface 703d are formed in mutually intersecting directions. That is, the first surface 703c and the second surface 703d are formed to be bent at a preset angle. The support portion 702b is formed from the second surface 703d. The support portion 702b may be formed at a preset angle with respect to the second surface 703d, and the support portion 702b may be formed to be parallel to the first surface 703c. 
FIG. 6B(a), illustrates a first state of the clip module 703, and FIG. 6B(b) illustrates a second state of the clip module 703. In the first state, a gap space is formed between the support portion 702b and the first body 601. The first frame 401 may pass through the space. That is, in the first state, the first frame 401 passes through the gap space and is installed in the space between the hooked portion 703a and the first body 601.
The clip module 703 may further include an elastic member providing elastic force enabling the hooked portion 703a to move to the interior of the first body 601.
In a state in which the first frame 401 is installed in the space, the state may be changed to the second state. In the second state, the edge of the support portion 702b is tightly attached to the first body 601. That is, the hooked portion 703a is moved to the interior of the first body 601 through the hole 601′ (see FIG. 5A(a)). Accordingly, the gap space is removed and separation of the first frame 401 from the clip module 703 is blocked.
In the clip module according to the present exemplary embodiment, the first frame 401 cannot be separated in the direction of gravity, the optical device 600 may be installed in both leg portions.
Also, a problem in which the optical device 600 is separated due to vibrations applied to the first frame 401 in a state in which the clip module 703 is installed in the first frame 401 can be solved.
Although not specifically illustrated in the drawings, the clip module 703 may further include a fixing structure for maintaining the first and second states.
