Description

The present invention relates to a panel opening / closing mechanism and an acoustic device using the panel opening / closing mechanism.
About.

  Among acoustic devices such as car audio, there is a type equipped with a retractable operation panel. An example of the configuration of this type of acoustic apparatus is shown in FIG. A daughter board 3 is provided on the mother board 2 of the acoustic device 1, and the female side 4 a of the connector 4 is mounted on the daughter board 3. Further, a sub panel 5 is provided in the vicinity of the daughter substrate 3, and an arm member 6 projects from the sub panel 5 toward the front side. The arm member 6 is provided with a bearing 6a, and a support shaft 7a of the operation panel 7 is rotatably attached to the bearing 6a. Thereby, the operation panel 7 is rotatably supported by the bearing 6a.

  Further, the male side 4 b of the connector 4 is attached to the operation panel 7. The male side 4b is fitted into the female side 4a of the connector 4 when the operation panel 7 is closed. As a result, the female side 4a and the male side 4b of the connector 4 are energized. Further, as shown in FIG. 15, when the operation panel 7 rotates around the support shaft 7a and falls down, the male side 4b of the connector 4 comes out of the female side 4a along with the operation.

  An example of such an acoustic device 1 is described in Japanese Patent Laid-Open No. 9-32449.

Japanese Unexamined Patent Publication No. 9-32449 (see paragraph number 0036, FIG. 1 and FIG. 2)

  The acoustic device 1 described above has the following problems. That is, as shown in FIG. 16, in the current acoustic device 1, the vertical direction (vertical direction) between the support shaft 7 a and the A portion on the male side 4 b (the portion on the upper left side of the male side 4 b in FIG. 16). ) Is not so long, and the lateral distance b is not so short. Therefore, when the operation panel 7 rotates, the portion A draws a trajectory in which the height position with respect to the support shaft 7a is once increased (a trajectory indicated by a one-dot chain line in the figure). Therefore, it is necessary to increase the dimension c of the insertion port 4c on the female side 4a to form a space above the inside of the female side 4a so that the A portion does not hit the inside of the female side 4a.

  However, when the insertion port 4c on the female side 4a is widened, the positional deviation between the female side 4a and the male side 4b is likely to occur, and therefore, the problem of contact failure due to the positional deviation is likely to occur. In addition, when the insertion opening 4c is wide, a leaf spring is often used to ensure contact between the female side 4a and the male side 4b. However, in the case of a configuration using a leaf spring, the operation panel 7 is always subjected to a load of about 1 kg when opened and closed, making it difficult to insert and remove.

Is possible.

  As shown in FIGS. 5 and 6, the slide guide portion 50a is integrally provided with an arm portion 50b. The arm portion 50b is located on the lower side of the slide arm member 50, and the arm portion 50b protrudes away from the side of the slide guide portion 50a. Further, a support shaft 53 is provided on the arm portion 50b. The support shaft 53 is provided so as to protrude from the other side surface (the same side surface on which the guide pin 52 is provided) of the arm portion 50b. The support shaft 53 is inserted into a support hole 82 of the operation panel 80 which will be described later, so that the rotation of the operation panel 80 can be guided (supported).

  As shown in FIGS. 8 to 10, a fixed arm member 70 corresponding to the first arm member is provided on the other end side of the sub-panel 30 (on the right side in FIGS. 8 to 10). A support shaft 71 similar to that described above is provided on the side surface of the fixed arm member 70 that faces the arm portion 50b (operation panel 80) described above. That is, the operation panel 80 is rotatably supported by these two support shafts 53 and 71.

  As shown in FIGS. 1 to 3, the operation panel 80 as the second member has various operation buttons and a display (both not shown) on the panel surface 80a. The operation panel 80 includes a circuit board 81 therein, and a light source and the like are mounted on the circuit board 81, and switches (not shown) corresponding to various operation buttons are mounted. The circuit board 81 is provided with a light source circuit for causing the light source to emit light and a button circuit for transmitting operation signals corresponding to various operation buttons to the control circuit. Further, as shown in FIGS. 8 to 10, one support hole 82 is provided on each operation panel 80 on the lower side of both side surfaces existing at one end and the other end in the longitudinal direction. Each support hole 82 is a portion in which the above-described support shafts 53 and 71 are fitted, and the operation panel 80 is pivotally supported.

  As shown in FIG. 1 to FIG. 3 and FIG. 8 to FIG. 10, a male side 40b of the connector 40 (corresponding to the other side of the connector 40) is attached to the back side of the operation panel 80. Is mounted on the circuit board 81. The male side 40b of the connector 40 is provided at a site corresponding to the fitting of the connector 40 to the female side 40a. That is, the male side 40 b of the connector 40 is provided at a position where the distance from the slide arm member 50 is smaller than the distance from the fixed arm member 70 in the longitudinal direction of the operation panel 80.

  The operation panel 80 has a horizontally long size such as 1DIN or 2DIN, for example, and the slide arm member 50 and the fixed arm member 70 are respectively disposed on both ends of the horizontally long long side. Yes. That is, the front shape of the operation panel 80 is a substantially rectangular shape (a rectangular shape in which the direction of one side is longer than the direction of the other side), and slide arm members are provided at both ends in the longitudinal direction of the rectangular shape. 50 and the fixed arm member 70 are respectively attached.

  The operation of the panel opening / closing mechanism 11 having the above configuration and the acoustic device 10 using the panel opening / closing mechanism 11 will be described below.

  When the user presses an open / close button (not shown) provided on the operation panel 80, the opening operation of the operation panel 80 is executed, and the claw member 63 moves to the left in FIG. That is, the locked state between the claw member 63 and the hook portion 61b is released. Then, due to the urging force of the spring 64, the slide arm member 50 is pushed out toward the near side, and the state shown in FIG. 1 (FIG. 8) is changed to the state shown in FIG. 2 (FIG. 9). In this state, the operation panel 80 is pushed to the near side and the fixed arm member 70 does not pop out, so the operation panel 80 is pushed one side and rotated in the X direction as shown in FIG. It will be tilted.

  At this time, the male side 40 b of the connector 40 is extracted from the female side 40 a of the connector 40. In addition, the operation panel 80 is merely tilted parallel to the near side of the panel surface 80a, and does not fall to the near side.

  As shown in FIG. 8, in the closed state before the operation panel 80 is tilted, the portion of the male side 40b of the connector 40 that is the innermost side and close to the slit guide portion 30b (B portion of the male side 40b) ) And the support shaft 71, a distance p exists along the longitudinal direction of the sub-panel 30 (the operation panel 80 in the closed state). Further, a distance q exists between the portion B on the male side 40 b of the connector 40 and the support shaft 71 along the normal direction of the sub-panel 30. The relationship between the distances p and q and the distances a and b (see FIG. 16) in the above-described conventional example will be described.

  The conventional distance a is the distance a in the short direction of the operation panel 80, and the distance p in the present embodiment is the distance p in the longitudinal direction of the operation panel 80 in the closed state. As shown in FIGS. 8 to 10, the connector 40 is provided closer to the slide arm member 50 than the fixed arm member 70. For this reason, in the acoustic device 10 such as a car audio, for example, in the case of a size such as 1DIN having a small size in the vertical direction (vertical direction) compared to the horizontal direction, the distance p is larger than the distance a. Overwhelmingly large value. Further, it is clear that the distance p is larger than the distance a even in the size of 2DIN.

  Further, both the distance b and the distance q are distances from the center portion of the support shaft 71 to the back side of the male side 40b of the connector 40 in the normal direction of the sub-panel 30 (operation panel 80). The values are equal. Therefore, the locus drawn by the B portion (see FIG. 8) has a larger arc radius than the conventional locus drawn by the A portion (see FIG. 16). That is, the portion B rotates while drawing an arc having a gentle curve and a small curvature.

  As shown in FIG. 9, after the operation panel 80 is rotated in the direction of X and sufficiently protrudes toward the front side, the operation panel 80 is moved as shown in FIGS. 3 and 10. The panel surface 80a falls toward the near side and is directed downward. Such a tilting operation may be realized by a cam mechanism (not shown), or an inertial force due to a sudden stop of the slide arm member 50 may be used. Note that when the inertial force is used, the rotation speed increases as the operation panel 80 rotates. In this case, a buffer member may be provided to prevent the operation panel 80 from being accelerated.

  In this manner, the operation panel 80 is positioned at a position that does not interfere with the insertion of the recording medium, and the disc insertion slot 31 (see FIG. 4) appears. Then, the user can insert the recording medium from the disc insertion slot 31 and remove the recording medium after ejection.

  According to the panel opening / closing mechanism 11 having such a configuration and the acoustic device 10 using the panel opening / closing mechanism 11, the sliding arm member 50 is slid to fit between the female side 40a and the male side 40b of the connector 40. Comes off. That is, as shown in FIG. 8, there is a distance p between the portion B and the support shaft 71, and this distance p is larger than the conventional distance a. In particular, since the connector 40 is provided closer to the slide arm member 50 than the fixed arm member 70, the distance p becomes larger than the distance a. For this reason, the locus drawn by the rotation of the distance B is a gentle one with a small curvature. Accordingly, the moving distance of the B portion in the direction away from the support shaft 71 can be reduced, and the B portion can be prevented from interfering with the inner wall surface of the female side 40a of the connector 40.

  Therefore, it is not necessary to increase the size of the insertion port 41 on the female side 40a, and it is not necessary to use a special connector having a wide insertion port 41. Thereby, it is possible to use a general-purpose inexpensive connector 40, and it is possible to reduce the cost.

  Moreover, since it is not necessary to use the connector 40 with the wide insertion port 41, the position shift of the male side 40b which occurs when the connector 40 with the wide insertion port 41 is used does not occur. Thereby, the problem of contact failure due to misalignment does not occur. Further, since it is not necessary to use the connector 40 having the wide insertion port 41, it is not necessary to use a leaf spring which is necessary when the connector 40 having the wide insertion port 41 is used. As a result, a load of about 1 kg, for example, that is applied when the operation panel 80 is opened and closed is not applied to the operation panel 80, and the connector 40 can be easily inserted and removed. Further, since the insertion port 41 of the connector 40 can be narrowed, the connector 40 can be downsized.

  Moreover, since the load of the load is greatly reduced, no abnormal noise is generated when the male side 40b is inserted and removed, and the product image for the user can be improved. That is, it is possible to give the product a high-class feeling.

  The female side 40 a of the connector 40 is mounted on the mother board 21. This eliminates the need for a daughter board for mounting the female side 40a as in the prior art. Thereby, the number of parts and the cost can be reduced.

  Further, in the present embodiment, the slide arm member 50 slides toward the near side, whereby the other end side (the slide arm member 50 side) of the operation panel 80 is guided to slide toward the near side. . In particular, the slide arm member 50 includes an arm portion 50 b provided with a support shaft 53 protruding therefrom, and a slide guide portion 50 a in which the slide is guided by the guide hole 33. Thereby, the operation panel 80 is guided to slide well. In the closed state of the operation panel 80, the slide arm member 50 is housed in the arm housing portion 36, so that the slide arm member 50 does not protrude and become an obstacle.

  Although one embodiment of the present invention has been described above, the present invention can be variously modified in addition to this. This will be described below.

  In the above-described embodiment, the pushing mechanism 60 having the spring 64 is provided, and the pushing mechanism 60 pushes the slide arm member 50 to the near side, thereby realizing the turning toward the near side of the operation panel 80. . However, the configuration for realizing the rotation toward the front side of the operation panel 80 is not limited to the configuration of the above-described embodiment. Modification examples of the acoustic device and the panel opening / closing mechanism are shown in FIGS.

  The acoustic device 100 and the panel opening / closing mechanism 101 shown in FIGS. 11 to 13 include a push lever 110 that constitutes the push-out mechanism 60. When the push lever 110 slides toward the front side, the operation panel 80 is provided. Is pushed out toward the near side, and the operation panel 80 is turned.

  Further, in this configuration, instead of the slide arm member 50, an arm member 111 (corresponding to the second arm member) having only a portion corresponding to the arm portion 50a without the slide guide portion 50a is provided. The arm member 111 projects in advance by a predetermined length, and a long hole portion 112 (corresponding to a slide support portion) is formed along the length of the arm member 111. Further, a support shaft 113 protrudes from the lower side portion of the operation panel 80, and the support shaft 113 is fitted into the long hole portion 112. The arm member 111 may be configured to be slidable on the back side, and may be retractable when not in use.

  In the case of such a configuration, the operation panel 80 is pushed out toward the near side by the push lever 110. Accordingly, the operation panel 80 is rotated around the support shaft 71 (see FIGS. 8 to 10), and shifts from the closed state as shown in FIG. 11 to the slide state as shown in FIG. If the push lever 110 is pushed a little further from this state, as shown in FIG. 13, the operation panel 80 is rotated so as to hide the panel surface 80a, and the operation panel 80 can be brought down.

  In the above-described embodiment, the push-out mechanism 60 pushes the slide arm member 50 forward by the biasing force of the spring 64. However, the push-out mechanism 60 is not limited to the configuration using the urging force of the spring 64, and may be configured to push out the slide arm member 50 (push lever 110) using a drive source such as a motor or an actuator. . In this case, in order to control the driving of the driving source, it is preferable to use a control means configured separately from a control circuit or the like. When using the control means, for example, when the operation button is pressed, the control means transmits a predetermined operation signal to the drive source. As a result, the drive source is activated and the slide arm member 50 (push lever 110) is pushed out.

  In the above-described embodiment, the female side 40 a of the connector 40 is mounted on the mother board 21, and the male side 40 b of the connector 40 is mounted on the circuit board 81 of the operation panel 80. However, the relationship between the female side 40a and the male side 40b of the connector 40 may be reversed. That is, the male side 40b of the connector 40 may be one side of the connector 40 and the female side 40a of the connector 40 may be the other side of the connector 40.
