Abstract:
A display panel can transition between a fixed state and an inclined state, in accordance with linear reciprocal movement relative to a main body section of a main slider. When the main slider travels a prescribed distance in the forward direction from a position in the fixed state, a motion link comes in contact with the main slider.

Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to an electronic device including a main body having a fixing surface and a display unit capable of taking an inclined posture relative to the fixing surface. 
       BACKGROUND ART 
       [0002]    As a kind of the electronic device, a navigation device that is to be mounted on a vehicle or the like has been known. The navigation device includes a main body having a fixing surface in which a medium insertion opening is formed and a display unit having a display surface for displaying information. The display unit can take a fixed state in which the display unit is fixed to the fixing surface and an inclined state in which the display unit takes an inclined posture relative to the fixing surface. When the display unit is in the inclined state, the medium insertion opening is exposed, so that a medium can be inserted or discharged. When the display unit is in the fixed state, the medium insertion opening is covered by the display unit. When the display unit is in the fixed state, the display unit takes a posture parallel with the fixing surface. A transition operation of the display unit from the fixed state to the inclined state is also referred to as a tilt operation. 
         [0003]    Patent Literature 1 discloses an electronic device having a mechanism configured to enable the tilt operation. A display unit of the display device disclosed in Patent Literature 1 is supported by a plurality of arms. The display unit is configured to be rotatable about a support point of each arm. The electronic device disclosed in Patent Literature 1 has a movement part and a motor. The movement part is configured to be moveable in a front-back direction with respect to a main body by an operation of the motor. A front end portion of the movement part is fixed to one of the plurality of arms. As the movement part moves forwards, the display unit transitions to the inclined state.

     SUMMARY OF INVENTION 
     Technical Problem 
       [0004]    However, when the movement part moves forwards and thus the display panel transitions to the inclined state, if vibrations of a vehicle body accompanied by traveling of a vehicle are transmitted to the electronic device, an abnormal sound may be caused to each member of the electronic device. Specifically, the movement part moves forwards, so that the moment of the arm increases. Further, the arm is configured to support the display panel having a predetermined weight. At this state, when the vibrations accompanied by the traveling of the vehicle are transmitted to the electronic device, the display panel shakes up and down and the movement part is relatively largely bent, so that load is applied to each member of the electronic device and the abnormal sound is thus generated. 
         [0005]    It is therefore an object of the present invention to suppress an abnormal sound upon change in posture of a display unit of an electronic device and in an inclined state. 
       Solution to Problem 
       [0006]    In order to achieve the above object, according to an aspect of the present invention, there is provided an electronic device. The electronic device includes: 
         [0007]    a main body fixed to a fixing target and having a fixing surface, 
         [0008]    a display unit having a display surface for displaying information, 
         [0009]    a first movement part connected to a lower end of the display unit and configured to linearly reciprocally move relative to the main body, 
         [0010]    a second movement part configured to reciprocally move in parallel with the first movement part, 
         [0011]    a support part configured to support the display unit, 
         [0012]    a first connection part to which a lower end portion of the display unit is to be connected to be rotatable relative to the first movement part, 
         [0013]    a second connection part provided between the lower end portion and an upper end portion of the display unit and to which the display unit and one end portion of the support part are to be connected to be relatively rotatable, and 
         [0014]    a third connection part to which the other end portion of the support part is to be connected to be rotatable relative to the second movement part. 
         [0015]    The display unit can transition between a fixed state and an inclined state in accordance with the reciprocal movement of the first movement part. 
         [0016]    In the fixed state, the upper end portion and the rear end portion of the display unit are fixed to the fixing surface. 
         [0017]    In the inclined state, the display unit is spaced from the fixing surface and the display surface faces upwards obliquely. 
         [0018]    When the first movement part moves forwards by a first distance from a position in the fixed state, the support part is contacted to the first movement part. 
         [0019]    According to the above configuration, the bending of the first movement part, which is caused due to the vibrations to be transmitted from the fixing target, is suppressed, so that it is possible to suppress an abnormal sound from each member upon change in posture of the display unit and in the inclined state. Also, the stability of a posture change operation of the display unit is improved. 
         [0020]    The electronic device can be configured as follows. 
         [0021]    The first movement part is configured to further move forwards by a second distance after the first movement part is contacted to the support part until the display unit reaches the inclined state. 
         [0022]    According to the above configuration, the rigidity of the first movement part against the vibrations transmitted to be from the fixing target is further increased. Therefore, the bending of the first movement part is further suppressed, so that it is possible to further suppress the abnormal sound from each member upon change in posture of the display unit and in the inclined state. 
         [0023]    The electronic device can be configured as follows. 
         [0024]    The support part has a bent shape so as to form a corner part convex towards the first movement part, and 
         [0025]    the corner part is in contact with the first movement part. 
         [0026]    According to the above configuration, the bending of the first movement part is immediately suppressed after the display unit starts to transition to the inclined state. Therefore, it is possible to further suppress the abnormal sound from each member upon change in posture of the display unit and in the inclined state. 
         [0027]    The electronic device can be configured as follows. 
         [0028]    The first movement part has a sliding path extending in a direction of the reciprocal movement, 
         [0029]    a coupling pin inserted into the second movement part and the sliding path and configured to slide along the sliding path is provided, 
         [0030]    the coupling pin is positioned between a front end portion and a rear end portion of the sliding path when the first movement part and the support part are first contacted to each other, and 
         [0031]    the coupling pin is engaged with the rear end portion of the sliding path when the first movement part moves forwards by the second distance. 
         [0032]    According to the above configuration, since the coupling pin is engaged with the rear end portion of the sliding path in the inclined state of the display unit, even though the vibrations are transmitted from the fixing target, it is possible to suppress displacement and deformation of the first movement part and shaking of the display unit. Therefore, it is possible to further suppress the abnormal sound from each member upon change in posture of the display unit and in the inclined state. Also, the stability of the posture change operation of the display unit is secured.

       2. Configuration of Electronic Device 
       [0051]    In the below, a configuration of the electronic device  10  is described. First, a configuration is described when the display panel  2  is in the fixed state, with reference to  FIGS. 2 to 4 . In these drawings, some members are shown with being projected for convenience of explanation. 
         [0052]    As shown in  FIG. 2 , the display panel  2  is provided in front of (the +Y direction) the front panel  5 . When the display panel  2  is in the fixed state, the display panel  2  covers the substantially entire surface (front surface) of the front panel  5 . Thereby, the disc insertion opening  4  is covered by the display panel  2 . 
         [0053]    The electronic device  10  has a motor  21 , a plurality of gears  22  and a main slider  31 . The motor  21 , the plurality of gears  22  and the main slider  31  are provided on a bottom of the chassis  11 . The motor  21  is configured to generate a driving force. The plurality of gears  22  is configured to transmit the driving force of the motor  21  to the main slider  31 . 
         [0054]    The main slider  31  (an example of the first movement part) has a pair of left and right (the X-axis direction) sliding members  301  and a coupling member  311 . The pair of sliding members  301  extends in the front-back direction (the Y-axis direction) of the chassis  11 . Both sides of the chassis  11  are provided with a pair of guide rails  33 . Each sliding member  301  is engaged with the corresponding guide rail  33  and is kept to freely slide in the front-back direction (the Y-axis direction) of the chassis  11 . The coupling member  311  extends in the left-right direction (the X-axis direction) of the chassis  11  and is configured to couple front end portions of the pair of sliding members  301 . The main slider  31  is configured to slide in the front-back direction (the Y-axis direction), which is a direction intersecting with the front panel  5 , by the driving force generated from the motor  21 . 
         [0055]    Each sliding member  301  is formed with a pin sliding path  101 . The pin sliding path  101  is a long hole extending in the front-back direction (the Y-axis direction) of the chassis  11 . As shown in  FIG. 3 , a pair of guide paths  102  is formed at a front part of a bottom surface of the chassis  11 . A front end portion of each pin sliding path  101  overlaps with a rear end portion of the corresponding guide path  102 , as seen from the Z-axis direction. The electronic device  10  has a pair of coupling pins  51 . Each coupling pin  51  is inserted into the corresponding pin sliding path  101  and the corresponding guide path  102 . 
         [0056]    Each coupling pin  51  has a barrel cylinder having a flange (not shown) inserted into the part at which the pin sliding path  101  and the guide path  102  overlap each other, a friction ring fitted to the barrel cylinder and a screw screwed to the barrel cylinder. 
         [0057]    As shown in  FIG. 2 , the electronic device  10  has a sub-slider  32  (an example of the second movement part). The sub-slider  32  has a pair of sliding members  302  and a connection member  312 . The pair of sliding members  302  extends in the front-back direction (the Y-axis direction) of the chassis  11 . Each sliding member  302  is engaged with the corresponding guide rail  33  and is kept to freely slide in the front-back direction (the Y-axis direction) of the chassis  11 . The connection member  312  extends in the left-right direction (the X-axis direction) of the chassis  11 , and is configured to couple front end portions of the pair of sliding members  302 . Each coupling pin  51  is inserted into a predetermined part of the corresponding sliding member  302  in the upper-lower direction (the Z-axis direction). 
         [0058]    A pair of plate springs  52 , which are elastic members, is provided in the vicinity of left and right sides (the X-axis direction) of the chassis  11 . As shown in  FIG. 4 , each plate spring  52  is in contact with the corresponding sliding member  302  of the sub-slider  32 . Each plate spring  52  is configured to press the corresponding sliding member  302  towards the corresponding sliding member  301  of the main slider  31 . 
         [0059]    As shown in  FIG. 2 , the display panel  2  has a pair of shafts  401  and a pair of shafts  402 . The pair of shafts  401  is provided at substantially central portions in the upper-lower direction of left and right sides of the display panel  2 . The pair of shafts  402  is provided at lower portions in the upper-lower direction of left and right sides of the display panel  2 . The sub-slider  32  has a pair of shafts  403 . Also, the front end portion of each sliding member  302  of the sub-slider  32  forms an arm part  43 . Each shaft  403  is provided at the corresponding arm part  43 . 
         [0060]    The electronic device  10  has a pair of motion links  41  (an example of the support part). As shown in  FIG. 4 , each motion link  41  is a member having a first part LP and a second part SP. The first part LP is longer than the second part SP. The first part LP and the second part SP extend in intersecting directions and form a bent part CL. When the display panel  2  is in the fixed state, each of the first parts LP extends in the upper-lower direction and each of the second parts SP extends in the front-back direction. Each of the first parts LP is rotatably connected to the corresponding shaft  401  (which is an example of the second connection part). Each of the second parts SP is rotatably connected to the corresponding shaft  403  (which is an example of the third connection part). Thereby, one end portion of each motion link  41  and the display panel  2  are configured to freely rotate relative to each other about the corresponding shaft  401 . The other end portion of each motion link  41  is configured to freely rotate relative to the sub-slider  32  about the corresponding shaft  403 . 
         [0061]    The front end portion of each sliding member  301  of the main slider  31  forms an arm part  42 . Each arm part  42  is rotatably connected to the corresponding shaft  402  (which is an example of the first connection part). Thereby, the display panel  2  is configured to be rotatable relative to each arm part  42  about the corresponding shaft  402 . As described above, each sliding member  301  is engaged with the corresponding guide rail  33  provided for the chassis  11 , and is kept to freely slide in the front-back direction (the Y-axis direction). As shown in  FIG. 4 , each guide rail  33  has a plurality of convex portions. The plurality of convex portions is arranged at different positions in the front-back direction (the Y-axis direction). The plurality of convex portions is arranged at positions facing the sliding member  301 . The plurality of convex portions is kept to sandwich the sliding member  301  in the upper-lower direction. Each sliding member  302  of the sub-slider  32  is provided on the corresponding guide rail  33 . 
       3. Change in Posture of Display Panel 
       [0062]    In the below, change in posture of the display panel  2  is described. First, a forward (the +Y direction) moving process of the display panel  2  from the fixed state of  FIG. 2  is described with reference to  FIGS. 5 to 7 . 
         [0063]    When the user operates a command button displayed on the display  3  or a physical operation button, for example, an instruction signal for operating the display panel  2  is output. The motor  21  starts an operation in response to the instruction signal, and drives the plurality of gears  22 . The plurality of gears  22  is driven, so that the sliding member  301  engaged with one of the plurality of gears  22  is moved forwards (the +Y direction), as shown in  FIGS. 5 and 7 . That is, the main slider  31  is moved forwards. 
         [0064]    As each sliding member  301  is moved, each coupling pin  51  engaged with the front end portion of each pin sliding path  101  is moved forwards (the +Y direction) along each guide path  102  from the rear end portion thereof. Accompanied by this movement, the corresponding sliding member  302  of the sub-slider  32  also starts to move forwards. That is, as the main slider  31  is moved, the sub-slider  32  is moved in the same direction as the main slider  31 . 
         [0065]    As each sliding member  302  of the sub-slider  32  is moved, the corresponding motion link  41  supported to the shaft  403  provided for each arm part  43  also starts to move forwards. Also, since the arm part  42  of each sliding member  301  also starts to move forwards, the display panel  2  is moved forwards. At this time, since each arm part  42  is moved forwards earlier than the motion link  41 , the display panel  2  is moved with an inclined posture where the upper end thereof is located slightly posterior to the lower end thereof. 
         [0066]    As each sliding member  302  is moved, each coupling pin  51  reaches the front end portion of the corresponding guide path  102  and stops, as shown in  FIG. 6 . In this state, since each coupling pin  51  can continue to move along the corresponding pin sliding path  101 , the corresponding sliding member  301  continues to move forwards. In other words, each coupling pin  51  moves towards the rear end along the corresponding pin sliding path  101 , so that it moves rearwards relative to the corresponding sliding member  301 . 
         [0067]    In the below, an operation that is performed until the display panel  2  shown in  FIGS. 5 and 7  reaches the inclined state from a state where the display panel has moved forwards (the +Y direction) by a predetermined distance is described with reference to  FIGS. 8 to 10 . 
         [0068]    After each coupling pin  51  reaches the front end portion of the corresponding guide path  102 , the arm part  42  of the sliding member  301  continues to move forwards (the +Y direction), so that the lower end of the display panel  2  moves forwards, as shown in  FIG. 8 . Thereby, the display panel  2  is tilted so that the front surface (the display surface) thereof faces upwards obliquely. Upon the start of the operation, the upper end of the display panel  2  is spaced forwards from the surface (front surface) of the front panel  5 , as shown in  FIG. 7 . For this reason, when the display panel  2  transitions to the inclined state, the display panel  2  is not contacted to the surface of the front panel  5 . 
         [0069]    When the display panel  2  is tilted, each motion link  41  is contacted to the main slider  31 , as shown in  FIG. 9 . Specifically, a corner part CP (a part shown with a black square) of each motion link  41  is contacted to the corresponding sliding member  301 . The bent part CL of the motion link  41  forms a corner part that is convex towards the corresponding sliding member  301 . The corner part CP corresponds to the corner part. 
         [0070]    Since the corner part CP, which is convex towards the corresponding sliding member  301 , is contacted to the driving member  301 , the corner part CP and the corresponding sliding member  301  are contacted to each other immediately after the display panel  2  is tilted as the sliding member  301  is moved. Thereby, when the display panel  2  is tilted, the bending of each sliding member  301  is immediately suppressed, so that it is possible to suppress an abnormal sound from each member upon the change in posture of the display panel  2  and in the inclined state. In the meantime, at the time that each corner part CP and the corresponding sliding member  301  are contacted to each other, each coupling pin  51  is positioned between the front end portion and the rear end portion of the corresponding pin sliding path  101   
         [0071]    Herein, an operation that is performed until each corner part CP and the corresponding sliding member  301  are contacted to each other is described in detail. Each sliding member  301  is moved by a first distance, which is the predetermined distance, towards the front (the +Y direction) shown with an arrow AR 1  in  FIG. 9 , so that the display panel  2  is rotated in a clockwise direction (as seen from a right side) shown with an arrow AR 2  about the respective shafts  401 ,  402  serving as the rotary shafts. On the other hand, as can be clearly seen from the comparison of  FIGS. 7 and 9 , each motion link  41  is rotated in a counterclockwise direction (as seen from a right side) about the corresponding shaft  403 . As a result, the corner part CP of each motion link  41  and the corresponding sliding member  301  are contacted to each other, and a downward (vertical direction) force (bias) shown with an arrow AR 3  is applied to the contact part thereof. The first distance by which each sliding member  301  moves is about  10  cm on the basis of the position of the member  301  in the fixed state of the display panel  2 , for example. 
         [0072]    Herein, the parts of the plurality of convex portions provided for the respective guide rails  33 , which are contacted to the corresponding sliding member  301 , are denoted as contact parts TP 1 , TP 2  shown with black circles. For example, a contact part between the contact part TP 1  and the sliding member  301  is denoted as a first support point, and a distance from the first support point to the shaft  402  is denoted as a distance L 1 . On the other hand, a contact part between the contact part TP 2  and the sliding member  301  is denoted as a second support point, and a distance from the second support point to the shaft  402  is denoted as a distance L 2 . The distance L 1  is greater than the distance L 2 . As a result, regarding the moment generated at the shaft  402 , the moment based on the second support point is less than the moment based on the first support point. In this way, the second support point is provided in addition to the first support point, so that it is possible to securely suppress the bending of the sliding member  301 , thereby suppressing the abnormal sound from each member upon the change in posture of the display panel  2  and in the inclined state. As a result, the stability of the posture change operation of the display panel  2  is also improved. 
         [0073]    On the other hand, the downward force (bias) shown with the arrow AR 3  is applied at the second support point, so that an upward force (bias) shown with an arrow AR 4  is applied at the first support point. Also, an upward force (bias) shown with an arrow AR 5  is applied to the contact part between the contact part TP 2  and the sliding member  301 . In this way, the upward forces are received by the plurality of convex portions provided for the respective guide rails  33 , so that it is possible to securely suppress the bending of each sliding member  301 . Also, the corner part CP of each motion link  41 , which is used when tilting the display panel  2 , is brought into contact with the corresponding sliding member  301 . Thereby, as compared to a configuration where a member configured to contact each sliding member  301  is newly provided on a backside of the display panel  2 , for example, it is possible to reduce the number of components, thereby saving the manufacturing cost. 
         [0074]    As shown in  FIG. 10 , even after each corner part CP is contacted to the corresponding sliding member  301 , each sliding member  301  is further moved forwards by the second distance. The second distance is about 5 mm, for example. In this state, each coupling pin  51  is engaged with the rear end portion of the pin sliding path  101  formed in the corresponding sliding member  301 . 
         [0075]    At this time, a weight of the display panel  2  and a force with which the display panel  2  is tilted in the rotating direction of the arrow AR 2  are composed, so that a downward force denoted by an arrow AR 3   a  is generated at the second support point. That is, the force stronger than the downward force denoted with the arrow AR 3  of  FIG. 9  is applied to each sliding member  301 . In addition to this configuration, since each coupling pin  51  is engaged to the rear end portion of the corresponding pin sliding path  101 , even when the vibrations are transmitted from a vehicle body, each sliding member  301  is difficult to be displaced and deformed and the display panel  2  is difficult to be shaken. Therefore, it is possible to suppress the abnormal sound from each member upon the change in posture of the display panel  2  and in the inclined state and to secure the stability of the posture change operation of the display panel  2 . 
         [0076]    In this way, even after each corner part CP and the corresponding sliding member  301  are contacted to each other, each sliding member  301  is further moved forwards, so that each motion link  41  continues to rotate in the counterclockwise direction (as seen from a right side) and the downward force (bias) denoted with the arrow AR 3   a  increases at the contact part thereof. Thereby, it is possible to further increase the rigidity of each sliding member  301  against the vibrations to be transmitted from the vehicle body. As a result, the bending of each sliding member  301  is suppressed, so that it is possible to further suppress the abnormal sound from each member during the change in posture of the display panel  2  and in the inclined state. In the meantime, each sliding member  301  is moved, so that the respective distances from the first support point and the second support point to the shaft  402  are increased. Specifically, the distance L 1  becomes L 1   a  (L 1 &lt;L 1   a ), and the distance L 2  becomes L 2   a  (L 2 &lt;L 2   a ). 
         [0077]    As the downward force increases, the upward force (bias) denoted with an arrow AR 4   a  at the first support point (the contact part TP 1 ) and the upward force (bias) denoted with an arrow AR 5   a  at the second support point (the contact part TP 2 ) increase. However, since the corresponding forces are received by the plurality of convex portions provided for the respective guide rails  33 , it is possible to further suppress the bending of each sliding member  301 . 
         [0078]    When each sliding member  301  is moved and thus each coupling pin  51  is relatively retreated and reaches the rear end portion of the corresponding pin sliding path  101 , as described above, a sensor (not shown) detects the reaching and stops the operation of the motor  21 . Thereby, the driving of the plurality of gears  22  is also stopped and the movement of each sliding member  301  is also stopped. At this time, the display panel  2  is in the inclined state, and the disc insertion opening  4  is exposed to the user. 
         [0079]    After the user inserts or acquires a disc through the disc insertion opening  4 , the motor  21  rotates in a reverse direction to the operation of moving the display panel  2  to the inclined state. Thereby, each sliding member  301  starts to move rearwards (the −Y direction), and the display panel  2  gradually stands up. 
         [0080]    Each sliding member  301  is moved rearwards, so that each coupling pin  51  is moved forwards (the +Y direction) from the rear end portion of the corresponding pin sliding path  101 . When each coupling pin  51  reaches and is engaged to the front end portion of the corresponding pin sliding path  101 , each coupling pin  51  starts to move along the corresponding guide path  102 . Thereby, the display panel  2  is moved rearwards with the posture where the display surface faces upwards obliquely to some extent. As a result, the upper end portion of the display panel  2  is first contacted to the front panel  5  earlier than the lower end portion to which the driving force is applied. Thereby, the adhesion of the display panel  2  to the main body  1  is improved. 
       Modified Embodiments 
       [0081]    Although the illustrative embodiment of the present invention has been described, the present invention is not limited to the illustrative embodiment and a variety of modifications can be made. In the below, modified embodiments are described. All aspects including the above illustrative embodiment and modified embodiments to be described below can be appropriately combined. 
         [0082]    In the above illustrative embodiment, each motion link  41  is a single member having the first part LP and the second part SP. However, each motion link  41  may also be formed by bonding a plurality of members. For example, each motion link  41  may have a configuration where the first part LP and the second part SP provided as separate members are bonded at the bonding part CL. 
         [0083]    Also, each motion link  41  may have another appropriate shape inasmuch as it accomplishes the above operational effects by changing the posture of the display panel  2  and contacting the corresponding sliding member  301 . 
         [0084]    In the above illustrative embodiment, the electronic device  10  is fixed to the vehicle such as an automobile. However, the electronic device  10  may also be fixed in other places of buildings such as home, a store, an office, a factory and the like. 
         [0085]    In the above illustrative embodiment, the control functions of the electronic device  10  are implemented in the software manner by the calculation processing of the CPU in accordance with the programs. However, some of the control functions may be implemented by an electrical hardware circuit.
