Description:
TECHNICAL FIELD 
       [0001]    The present disclosure relates to a display audio apparatus which is equipped in a vehicle and which cooperates with a multifunctional portable phone to display information. 
       BACKGROUND 
       [0002]    In the related art, there has been proposed provision, on a vehicle, of an audio-visual apparatus (hereinafter referred to as “AV apparatus”) which outputs video and sound, a navigation apparatus which provides route information, or the like. However, there has been a problem in that the AV apparatus and navigation apparatuses dedicated for equipment on a vehicle are expensive. 
         [0003]    In consideration of this, there is proposed use of a multifunctional portable terminal such as, for example, a smartphone or the like in place of the AV apparatus or the navigation apparatus dedicated for equipment on the vehicle. Specifically, it is proposed to install navigation software and player software of music or video in the smartphone or the like, and to carry the smartphone into the vehicle. 
         [0004]    In addition, in recent years, display audio apparatuses (hereinafter referred to as “DA apparatuses”) which cooperate with the smartphone are also proposed. The DA apparatus is electrically connected to the smartphone, displays an output from the smartphone on a display, and inputs an operation received from the user into the smartphone. Such a DA apparatus has a display at a position easily viewable from the driver, such as on the dashboard. By displaying information from the smartphone on the DA apparatus, it becomes possible for the user to more comfortably handle various information. Further, such a DA apparatus can be formed inexpensively compared to the AV apparatus and the navigation apparatus dedicated for vehicle equipment. 
       SUMMARY 
     Technical Problem 
       [0005]    In the DA apparatus of the related art, however, the smartphone is set on a cradle (docking station) placed outside the DA apparatus; for example, on the dashboard, and is exposed to the outside. In this case, the smartphone and the cradle may disturb the unified look of the interior of the vehicle, and have caused inferior appearance. In addition, depending on the location of placement of the cradle, there have been possibilities that human hands and fingers may contact the smartphone and the cradle, resulting in damages, or that the smartphone or the like may block the field of view. In addition, in this configuration, a part of a harness which electrically connects the smartphone and the DA apparatus is also exposed to the outside, which also results in inferior appearance, hooking of the hands and fingers, or the like. 
         [0006]    An advantage of the present disclosure lies in the provision of a DA apparatus which can reliably prevent appearance degradation and hooking of hands and fingers. 
       Solution to Problem 
       [0007]    According to one aspect of the present disclosure, there is provided a display audio apparatus that is equipped on a vehicle and that cooperates with a transportable information terminal to output information, the display audio apparatus comprising: a main body that is fixed on a fixed member; a display that can be opened and closed with respect to the main body; a holder that holds the information terminal, that is connected to a back surface of the display, and that is opened and closed with the main body; an electric circuit that is provided on the main body, that displays, on the display, information which is output from an information terminal held on the holder, and that transmits an operation instruction from a user to the information terminal; and an open/close mechanism that switches the display between an open state in which the holder is exposed to an outside of the case and a closed state in which the holder is positioned inside the case. 
         [0008]    According to another aspect of the present disclosure, the open/close mechanism comprises an urging member that urges the display forward, wherein the urging member moves the display in an open direction when the closed state is released, and causes the information terminal held on the holder to closely contact a wall surface of the holder in the closed state. 
         [0009]    According to another aspect of the present disclosure, the apparatus further comprises a harness that electrically connects the information terminal held on the holder and the electric circuit, wherein, in the closed state, the harness is stored in the case in a connected state to the information terminal. 
       Advantageous Effects of Invention 
       [0010]    According to various aspects of the present disclosure, because the display is set to be openable/closable and the holder that holds the information terminal is provided on the back surface of the display, the information terminal can be stored in the DA apparatus. As a result, the appearance degradation and hooking of hands and fingers can be more reliably prevented.

     DESCRIPTION OF EMBODIMENTS 
       [0024]    An embodiment of the present disclosure will now be described with reference to the drawings.  FIG. 1  is a block diagram showing an electrical structure of a display audio apparatus (hereinafter referred to as “DA apparatus”)  10  according to an embodiment of the present disclosure. 
         [0025]    The DA apparatus  10  is a device that cooperates with a smartphone  100  which is a transportable information terminal, outputs information which is output from the smartphone  100 , and inputs an operation received from a user to the smartphone  100 . On the smartphone  100  there are installed, for example, navigation software for guiding a route, player software for outputting video or music, or the like. The DA apparatus  10  launches software designated from the user among the software installed in the smartphone  100 , and displays on a display  26  of the DA apparatus  10  information which is output from the smartphone  100  (for example, a route guide screen, a route guide sound, a music sound, video). 
         [0026]    As shown in  FIG. 1 , a controller  20  of the DA apparatus  10  is electrically connected to the smartphone  100  via a harness  24 . The harness  24  is a cable complying with an HDMI (registered trademark) standard. The harness  24  is electrically connected to the controller  20  for exchange of signals. In addition, the harness  24  also functions as an electric power supplying harness for the smartphone  100 , and is also electrically connected to a charger  23 . 
         [0027]    The controller  20  drives a liquid crystal display  12  and a speaker  14  according to a video signal and a sound signal supplied from the smartphone  100 , to output video and sound. The controller  20  also generates an operation signal based on a touch operation detected by a touch panel  16  and outputs the operation signal to the smartphone  100 . When the smartphone  100  has a sound operation function, a microphone  18  may be provided on the DA apparatus  10 , and a sound signal collected by the microphone  18  may be sent to the smartphone  100  as an operation signal. In addition, although not shown in  FIG. 1 , the DA apparatus  10  may include a simple operation device such as, for example, a switch, a button, a volume switch, a keyboard, or the like. A memory  22  stores a program for driving the DA apparatus  10 , control parameters, and the like. 
         [0028]    As shown in  FIG. 2 , the DA apparatus  10  having such a structure is assembled in a position in the car cabin of the vehicle where the occupants can easily see; for example, a position adjacent to the instrument panel on the dashboard  102 . A main body (not viewable in  FIG. 2 ) of the DA apparatus  10  is embedded inside the dashboard  102 , and normally, of the DA apparatus  10 , only a panel  40  (refer to  FIG. 3 ) forming the display  26  (that is, the liquid crystal display  12  on which the touch panel  16  is provided) is exposed to the outside. In this manner, by assembling the DA apparatus  10  in a state where only the display  26  is exposed, it becomes possible to prevent unintentional contact of the hands and fingers of the user on the DA apparatus  10  and blocking of the field of view of the user by the DA apparatus  10 . Meanwhile, because various types of information can be provided with a screen larger than the smartphone  100  and a speaker having a higher performance than that of the smartphone  100 , the user can more comfortably use various software (navigation software and player software) installed in the smartphone  100 . 
         [0029]    In the related art, the smartphone  100  connected to the DA apparatus  10  is placed outside the DA apparatus  10 . That is, in the related art, a docking station, or a cradle, of the smartphone  100  is placed on an outer surface of the dashboard  102 , and the smartphone  100  is attached to the cradle. In this case, the smartphone  100  is positioned in a manner protruding from the dashboard  102 . As a result, the unified look of the interior in the car cabin is disturbed, appearance is degraded, and unintentional contact of the hands and fingers of the user on the smartphone  100  and the cradle may occur, possibly resulting in damages and erroneous operations of the smartphone  100  or the like. Moreover, there has been a possibility that the smartphone  100  protruding to the outside blocks the field of view of the user. Furthermore, in this case, the harness  24  which electrically connects the smartphone  100  and the DA apparatus  10  is also exposed to the outside. The harness  24  exposed to the outside in this manner may degrade the appearance, and possibly hook the user&#39;s hands and fingers, also resulting in damages and erroneous operations of the smartphone  100  and the DA apparatus  10 . 
         [0030]    In consideration of this, in the present embodiment, a holder that holds the smartphone  100  is provided at the back of the display  26 . This will now be described with reference to  FIGS. 3-7 .  FIG. 3  is an exploded perspective view of the DA apparatus  10 .  FIGS. 4 and 5  are perspective views of the DA apparatus  10  in which the display  26  is set in an open state.  FIG. 6  is a side view of the DA apparatus  10  in a closed state,  FIG. 7  is a side view of the DA apparatus  10  during an opening operation, and  FIG. 8  is a side view of the DA apparatus  10  after completion of the opening operation. 
         [0031]    The DA apparatus  10  can be largely divided into a main body  28  embedded in and fixed on the dashboard  102 , and the display  26  which can be opened and closed with respect to the main body  28 . The display  26  is formed by assembling the panel  40 , and an electrode  42 , a relay board  48 , and a TFT  46  which form a touch panel onto a housing  44  made of a resin or the like, and covering the back with a cover  50  (refer to  FIG. 3 ). In the present embodiment, a holder unit  72  for holding the smartphone  100  is formed on a back surface of the cover  50  covering the back of the display  26  (refer to  FIG. 4 ). As shown in  FIG. 4 , the holder unit  72  is formed from a frame member  50   a  formed corresponding to a shape of the smartphone  100 . Alternatively, the holder unit  72  may be members of other forms, for example, a member surrounding only the four corners of the smartphone  100 , in place of the frame member  50   a , so long as the holder unit  72  can hold the smartphone  100 . 
         [0032]    In addition, in the present embodiment, the display  26  is formed to be openable/closable with respect to the main body  28 . An open/close mechanism  30  of the display  26  will be described in detail later. The display  26  can be switched between a closed state in which the holder unit  72  is positioned within the main body  28 , and an open state in which the holder unit  72  is exposed to the outside. More specifically, when the display  26  is pushed toward the deeper side in the closed state as shown in  FIG. 6 , the display  26  moves straight forward, protrudes to the outer side from the surface of the dashboard  102  to form a state shown in  FIG. 7 , rotates forward, and assumes the open state in which the holder unit  72  is exposed to the outside, as shown in  FIG. 8 . 
         [0033]    When the display  26  is to be set to the closed state, the display  26  in the open state may be pressed toward the deeper side. The holder unit  72  has a size to allow storage of the entire smartphone  100 , and the display  26  can be set to the closed state while the smartphone  100  is stored in the holder unit  72 . In other words, according to the present embodiment, when the display  26  is closed, the smartphone  100  is stored completely inside the main body  28  of the DA apparatus  10 . As a result, the smartphone  100  is not exposed to the outside of the DA apparatus, and unintentional contact between the smartphone  100  and the hands and fingers, blocking of the field of view by the smartphone  100 , or the like can be reliably prevented. 
         [0034]    Moreover, in the present embodiment, the harness  24  (refer to  FIGS. 4 and 5 ) which electrically connects the DA apparatus  10  and the smartphone  100  is stored in the main body  28  of the DA apparatus  10 . That is, on a frame  67  provided on the main body  28  of the DA apparatus  10 , there is formed a terminal storage unit  67   a  which stores a connection terminal  24   a  provided at a tip of the harness  24  (refer to  FIGS. 4 and 5 ). On the terminal storage unit  67   a , there is formed an insertion hole  67   b  through which the harness  24  is inserted, and the harness  24  can move back and forth in the insertion hole  67   b . When the smartphone  100  is mounted on the holder unit  72 , as shown in  FIG. 5 , the harness  24  is extended forward, and the connection terminal  24   a  is connected to the smartphone  100 . When the display  26  is set to the closed state in this state, the harness  24  can be stored completely inside the DA apparatus  10  along with the smartphone  100 , and thus, unintentional hooking of the hands and fingers on the harness  24  can be completely prevented. 
         [0035]    Next, a mechanical structure of the DA apparatus  100  will be described. As already described, the DA apparatus  10  can be mechanically divided into the main body  28  embedded in the dashboard  102 , and the display  26  which can be opened and closed with respect to the main body  28 . On the main body  28 , there are mounted a plurality of iron plates  70  forming a case of the DA apparatus  10 , and a plurality of circuit boards  68  forming the controller  20  and the memory  22 . 
         [0036]    In front of the circuit boards  68 , a base member  62  is placed, and a separation plate  64  is fixed on the base member  62 . The separation plate  64  is a member which stands approximately vertical, and a plurality of insertion holes  64   b  through which a forward/backward movement bar  54   a  passes are formed near a central area of the separation plate  64 . 
         [0037]    The base member  62  is a member which is fixed on the case of the DA apparatus  10 . On the ends in the width direction of the base member  62 , a side wall  74  which stands approximately vertical is provided. The side wall  74  is a constituting element of the open/close mechanism  30  which switches the open/close states of the display  26 . On the side wall  74 , there are formed an arm hole  74   a  through which an arm  56  is inserted, a guide hole  74   b  for guiding movement of a guiding protrusion  58   a , or the like, which will be described later in detail. 
         [0038]    Further, on the base member  62 , a placement arm for attaching a lock switch  66  is provided in a standing manner. The lock switch  66  also is a constituting element of the open/close mechanism  30  which switches the open/close states of the display  26 . The lock switch  66  can assume an engaged state where the lock switch  66  engages a part of the display  26  and maintains the closed state, and a disengaged state in which the engagement is released. The state of the lock switch  66  can be switched by pressing a movable pin  82  protruding on a front surface of the lock switch  66 . 
         [0039]    On a front surface of the base member  62 , a forward/backward movement plate  54  is provided. The forward/backward movement plate  54  is a plate member having an approximate flat plate shape, and a plurality of the forward/backward movement bars  54   a  extending in the horizontal direction are provided on a back surface of the forward/backward movement plate  54 . As already described, the forward/backward movement bar  54   a  is inserted into the insertion hole  64   b  of the separation plate  64  which is fixedly provided, and the forward/backward movement plate  54  can be moved forward and backward with respect to the separation plate  64 . In addition, a coil spring  60  which urges the forward/backward movement plate  54  in the open direction is attached to the forward/backward movement bar  54   a.    
         [0040]    As already described, the display  26  comprises the panel  40 , the electrode  42 , the relay board  48 , the housing  44 , and the cover  50 . Of these elements, on a back surface of the cover  50 , the frame member  50   a  forming the holder unit  72  is formed. A cover side engagement member  50   b  which engages the lock switch  66  protrudes from an end on the back surface of the cover  50  (refer to  FIGS. 9 and 10 ). In addition, a pusher  52  which contacts the lock switch  66  is attached near the cover side engagement member  50   b . Near a lower end of the cover  50 , a guide member  58  is fixed, and the cover  50 , and, consequently, the entire display  26  to which the cover  50  is assembled, is moved forward and backward, and is rotated along with the guide member  58 . Further, the arm  56  is also attached to the cover  50 . The arm  56  moves forward and backward along with the cover  50  and the guide member  58 , but does not rotate with the cover  50  or the like. The arm  56  always maintains a horizontal orientation. 
         [0041]    Next, a mechanism for opening or closing the display  26  in the DA apparatus  10  having such a structure will be described with reference to  FIGS. 9 and 10 .  FIGS. 9 and 10  are both perspective views emphasizing the members contributing the opening/closing of the display  26  in the DA apparatus  10 .  FIG. 9  shows the closed state and  FIG. 10  shows the open state. 
         [0042]    The open/close mechanism  30  which opens and closes the display  26  with respect to the main body  28  comprises the base member  62 , the forward/backward movement plate  54 , the arm  56 , the guide member  58 , the lock switch  66 , or the like. Specifically, in the closed state, the cover side engagement member  50   b  is engaged with a switch side engagement member  86  provided on the lock switch  66 . When the display  26  is pressed in this state, the engagement between the two engagement members  50   b  and  86  is released. When the engagement members are disengaged, the forward/backward movement plate  54  and the display  26  positioned in front of the forward/backward movement plate  54  move forward by an urging force of the coil spring  60  which urges the forward/backward movement plate  54  forward. 
         [0043]    Here, because the guiding protrusion  58   a  formed in the guide member  58  is passed through the guide hole  74   b  formed on the side wall  74 , the guide member  58 , and, consequently, the display  26 , is moved in a direction along the guide hole  74   b ; that is, forward in the horizontal direction. 
         [0044]    During the process of moving forward, the guiding protrusion  58   a  moves out from the guide hole  74   b , and becomes rotatable with respect to the arm  56 . In addition, the arm  56  inserted into the arm hole  74   a  of the side wall  74  contacts an arm stop  57  attached to the side wall  74  after moving forward for a certain distance, the forward movement thereof is restricted, and further forward movement of the display  26  is prevented. When the display  26  is set in this state, the display  26  is rotated forward about a junction axis with the arm  56  by its own weight. As a result, the open state as shown in  FIG. 10  is achieved. Alternatively, in order to more actively rotate the display  26 , an elastic member for rotation which urges the cover  50  in the forward direction may be provided between the forward/backward movement plate  54  and the cover  50 . 
         [0045]    In order to set the display  26  in the open state to the closed state, the display  26  may be pressed toward the deeper side against the urging force of the coil spring  60 . When the display  26  is pressed to a position where the pusher  52  presses the lock switch  66 , a part of the lock switch  66  engages the cover side engagement member  50   b , and the closed state is maintained. 
         [0046]    Here, even in the closed state, the forward/backward movement plate  54  always presses the cover  50  in the forward direction by the urging force of the coil spring  60 . In the case where the smartphone  100  is stored in the holder unit  72 , the forward/backward movement plate  54  presses the smartphone  100  toward the side of the cover  50 . As a result, rattling and vibration of the smartphone  100  in the holder unit  72  can be effectively prevented, along with uncomfortable vibration sound and damages to the smartphone  100  due to the vibration and shock. In addition, as is clear from the description above, in the present embodiment, a common member is used for the elastic member for opening and closing the display  26  and the elastic member for preventing rattling of the smartphone  100 . As a result, the number of components can be reduced, and the DA apparatus  10  can be formed with a reduced cost. 
         [0047]    The structure of the lock switch  66  is not particularly limited so long as the lock switch  66  can be switched between the engaged state and the disengaged state, and known structures may be employed, such as a structure disclosed in JP 2006-137224 A.  FIGS. 1A and 11B  are diagrams showing an example structure of the lock switch  66 .  FIG. 11A  shows the engaged state and  FIG. 11B  shows the disengaged state.  FIG. 12  is an exploded perspective view of the lock switch  66 . 
         [0048]    The lock switch  66  comprises a housing  80  having a rectangular tube shape and which is fixedly placed, the movable pin  82  and a sliding member  84  which move forward and backward in the housing  80 , the switch side engagement member  86  which moves forward and backward in the radial direction of the housing  80 , and elastic members  88  and  90  which urge the movable pin  82  and the sliding member  84 . 
         [0049]    The movable pin  82  and the sliding member  84  are urged by the first and second elastic members  88  and  90  in the forward direction (downward in the figures). A tip of the movable pin  82  protrudes from a hole formed on a tip surface of the housing  80  toward the outside, and contacts the pusher  52 . 
         [0050]    The sliding member  84  has a box-shaped unit  84   a  having two opposing surfaces opened, and a cam unit  84   b  connected to the box-shaped unit  84   a . Of the box-shaped unit  84   a , on two surfaces orthogonal to the movement direction, there is formed a cam hole  84   c  extending in a slanted direction toward the front direction so that the cam moves toward the disengagement direction (right direction in the figures). A shaft  94  attached to the switch side engagement member  86  is inserted through the cam hole  84   c.    
         [0051]    In the lock switch  66  having the above-described configuration, in the engaged state, as shown in  FIG. 11A , the sliding member  84  and the movable pin  82  are moved forward (downward in the figures), and the switch side engagement member  86  is engaged with the cover side engagement member  50   b . In this state, the cover side engagement member  50   b , and consequently, the display  26 , cannot move forward, and the closed state can be maintained. 
         [0052]    In this state, when the movable pin  82  is pressed toward the deeper side by the pusher  52 , the movable pin  82  and the sliding member  84  are both moved toward the deeper side (upward in the figure). With this movement, the shaft of the switch side engagement member  86  moves along the cam hole  84   c , and, consequently, the switch side engagement member  86  moves in the disengagement direction (right direction in the figure). As a result, the engagement between the switch side engagement member  86  and the cover side engagement member  50   b  is released, to achieve the state of  FIG. 11B . When the pressing by the pusher  52  is released, the sliding member  84  and the movable pin  82  move in the forward direction again by the urging force of the elastic member. 
         [0053]    When the state is to be returned from the disengagement state to the lock state, the display  26  can be pressed toward the deeper side, to press the movable pin  82  with the pusher  52  again toward the deeper side. With such a process, the movable pin  82  and the sliding member  84  again move toward the deeper side, the switch side engagement member  86  moves in the lock releasing direction, and the state of  FIG. 11B  is achieved. The cover side engagement member  50   b  moves with the pusher  52  toward the deeper side, and in this process, because the cover side engagement member  50   b  does not interfere with the switch side engagement member  86 , the cover side engagement member  50   b  can be moved completely to the deeper side. After the switch side engagement member  86  has moved completely to the deeper side, the pressing by the pusher  52  may be released so that the movable pin  82  and the sliding member  84  move forward by the urging force of the elastic member, and, consequently, the switch side engagement member  86  also moves in the engagement direction (left direction in the figure). Finally, the lock state as shown in  FIG. 11A  is achieved. 
         [0054]    The structure of the lock switch  66  described herein, however, is merely exemplary, and other structures may be employed so long as the engagement state with a part of the display  26  can be suitably switched. For example, in the present embodiment, the lock switch  66  which mechanically switches between the engagement and disengagement states is employed, but alternatively, the engagement and disengagement may be electrically switched. For example, a button for switching between open/closed states may be provided on the display  26 , and the engagement and disengagement may be switched by use of an electromagnetic plunger or the like which moves forward and backward upon receiving a pressing signal of the button. 
         [0055]    Further, so long as the transportable information terminal can be held on the back surface of the display  26  of the DA apparatus  10 , the other structures may be suitably modified. For example, in the present embodiment, during the opening operation of the display  26 , the display  26  is slid forward and then rotated forward. However, it is also possible to execute only one of the forward sliding and the forward rotation if a sufficient space can be secured for setting the smartphone  100 . Further, in place of the sliding or the rotating forward, it is also possible to employ a structure in which the opening/closing operations are done by rotating about a vertical axis provided at left and right ends of the display  26 ; that is, a single-swing door structure. 
         [0056]    In addition, in the present embodiment, the smartphone  100  and the DA apparatus  10  are electrically connected via the harness  24 , but alternatively, other connection forms may be employed so long as the electric connection member can be stored completely inside the DA apparatus  10 . For example, a connection terminal may be fixedly placed at a position which contacts the connection terminal of the smartphone  100  when the smartphone  100  is set in the holder unit  72 , so that, upon setting the smartphone  100  on the holder unit  72 , the connection terminal of the DA apparatus  10  and the connection terminal of the smartphone  100  are automatically connected to each other. In addition, the electrical connection member is not limited to a wired structure and may be a wireless structure, so long as the electric signals can be exchanged. 
         [0057]    Moreover, in the present embodiment, a DA apparatus which is connected to the smartphone  100  is exemplified, but the information terminal is not limited to the smartphone, and the DA apparatus may be connected to a PDA or a tablet terminal, so long as the information terminal is a transportable information terminal. 
         [0058]    In either configuration, by providing the holder unit of the transportable information terminal on the back surface of the display  26  of the DA apparatus, it becomes possible to improve the appearance and to effectively prevent problems such as damages of the information terminal and blocking of the field of view by the information terminal.
