Description

  The present invention relates to an in-vehicle device, and particularly to an in-vehicle device having a front panel.

  Various audio devices, car navigation devices, and the like are incorporated on a vehicle instrument panel at a position intermediate between the driver seat and the passenger seat. Therefore, it is possible to enjoy music while driving or to know the course to be taken by the display unit of the car navigation device.

  In such an in-vehicle device, a portion exposed on the instrument panel is usually a front panel, and the front panel is constituted by, for example, a liquid crystal display panel. Therefore, in the case of an audio device, various input operations can be performed with the touch switch provided on the instrument panel, or a list of tracks being recorded on the music being played or the recording medium is also available. Can be displayed. In the case of a car navigation device, the position of the vehicle and the traveling direction are displayed on the map by the display unit on the front panel.

  In this way, according to the configuration in which the front panel having a display function is arranged on the front side portion, it is necessary to insert or eject the optical disc to the optical disc player arranged on the rear side. Therefore, as disclosed in, for example, Japanese Patent Application Laid-Open No. 9-180332 and Japanese Patent Application Laid-Open No. 11-306630, the front panel on the front side is drawn forward, and at this time, it is directed obliquely upward. Thus, a slit-like gap is formed in the upper part of the front panel and on the sub-panel, and a recording medium such as an optical disk is inserted and removed through this gap.

  An example of a configuration that allows such a recording medium to be inserted and removed will be described with reference to FIGS. As shown in FIG. 18, the front panel 15 is configured to receive the pin 35 provided at the lower end portion thereof in the connecting hole 34 on the distal end side of the arm 33 of the moving frame 21. A pin 41 provided on the arm 40 on the upper end side of the front panel 15 is guided by a vertical guide groove 42 provided in the sub-panel 11.

  When the driving means 51 is driven, its operation changes sequentially as shown in FIGS. 18 to 21, and when the moving frame 21 is pushed forward by the driving means 51 to the right in the drawing, While the lower end portion of the front panel 15 is moved forward, the upper end side pin 41 gradually descends along the guide groove 42 of the sub panel 11 so that the front panel 15 faces obliquely upward at this time. When it is lowered greatly, the disc insertion opening provided in the sub-panel 11 is opened, so that the optical disc can be inserted and removed.

  However, in this type of mechanism, when the moving frame 21 is pushed forward by the driving means 51, the front panel 15 is substantially rotated counterclockwise around the upper pin 41 immediately after the start of the moving frame 21. In order to perform the movement, the upper part of the front panel 15 on the front end side comes into contact with the lower edge of the upper part of the mounting frame 48 mounted on the instrument panel, thereby moving the moving frame by the driving means 51. A large load is applied to 21 extrusion operations. Alternatively, there is a possibility that the pushing operation of the front panel 15 as shown in FIGS.

In order to solve such a problem, for example, by making the opening of the mounting frame 48 far away from the upper surface of the front panel 15, interference between the front panel 15 and the mounting frame 48 is prevented. Is possible. However, when the size of the opening portion of the mounting frame 48 that forms a gap with the front panel 15 is increased, the front panel 15 can be removed when the front panel 15 is completely stored as shown in FIG. A large gap is formed at the upper end, which causes a problem of deterioration in design.

  The problem of the present invention is that when the front panel provided on the front side of the in-vehicle device is pulled out so as to face obliquely upward, the upper edge of the front panel and the mounting frame fixed to the instrument panel interfere with each other. This is to provide an in-vehicle device that does not apply a large load to the driving means.

  Another problem of the present invention is that even when the clearance between the front panel and the upper edge of the mounting frame fixed to the instrument panel is small, when the front panel is pushed diagonally upward by the driving means, An object of the present invention is to provide an in-vehicle device in which the upper end of the front panel and the lower edge of the upper portion of the mounting frame do not interfere with each other.

  Still another object of the present invention is to increase the clearance between the front panel and a mounting frame fixed to the instrument panel in an in-vehicle device in which the front panel is pushed obliquely upward by the driving means. It is providing the vehicle equipment which prevented the deterioration of the design property by a thing.

Here, a mounting frame is attached to the outer periphery of the sub-panel so as to be fixed to the instrument panel, so that the upper portion of the front panel does not interfere with the lower surface on the upper side of the opening of the mounting frame by the guide groove . It is preferable to do. The front panel may be a liquid crystal display panel. The in-vehicle device may be an optical disc player. The on-vehicle device may be a car navigation device .

  The main invention of the present application is that in an in-vehicle device having a front panel, the lower part of the front panel is movable in the front-rear direction with respect to the main body side of the device, and the upper part is movable in the vertical direction with respect to the main body side of the device The front panel is inclined when the front panel is pulled out, and the upper end side of the guide means for guiding the upper part of the front panel so as to be movable in the vertical direction is bent backward.

  Therefore, according to such an in-vehicle device, when the front panel is pulled out so as to be inclined, the upper end side of the guide means for guiding the upper portion of the front panel is bent backward at the start operation. Will perform a parallel movement substantially forward, thereby preventing the upper end of the front panel from interfering with a mounting frame fixed to another member, such as an instrument panel.

Another main invention of the present application is an in-vehicle device having a front panel, and in an in-vehicle device incorporated in an instrument panel of an automobile, the vehicle is arranged in the main body of the in-vehicle device and moves in the front-rear direction, and the front end portion A moving frame in which a lower portion of a front panel is rotatably connected, a sub panel that is attached so as to close a medium insertion port of a main body of the in-vehicle device, and that extends a front end side of the moving frame by the opening; A fulcrum pin formed on the side wall and provided above the front panel is received, and an upper end portion extending linearly forward and downward from the upper end, and bent from the lower end of the upper end portion and linearly downward. a central portion extending so as to have a formed guide groove and a lower portion extending in the bent from the lower end of the central portion a straight line forwardly and downwardly Those were.

Therefore, according to such an in-vehicle device, when the front panel is pulled out so as to be inclined, the upper end side of the guide groove that guides the upper part of the front panel is bent backward in the starting operation. Such a bent portion allows the front panel to move forward with almost no pivoting motion, and thereby the front panel relative to the edge portion of the opening of a member such as a mounting frame mounted on the instrument panel. It becomes possible to prevent the interference of the upper surface.

  The present invention will be described below with reference to embodiments shown in the drawings. 1 to 3 show an in-vehicle disc player according to the present embodiment. This in-vehicle disc player includes a chassis 10 made of sheet metal. The chassis 10 has a substantially box shape with the front open, and also serves as a housing of the optical disk player. Then, a rectangular dish-shaped sub-panel 11 is attached so as to cover the front side opening of the chassis 10. The sub-panel 11 is provided with a slit-like insertion opening 12 at a position on the upper side thereof so as to extend in the lateral direction. Yes. In addition, the sub-panel 11 is formed with a U-shaped opening 13 with both ends extending highly at the lower part thereof. This opening 13 is for extruding the front panel mentioned later forward.

  The front panel 15 is attached to a portion on the front end side of the sub-panel 11, and its main part is constituted by a display unit 16. The display unit 16 may be a liquid crystal display panel, for example. A plurality of, for example, three operation buttons 17 on the left and right sides are attached to the lower side of the front panel 15.

  The bottom of the chassis 10 is composed of a bottom plate 20 as shown in FIG. 3, and a substantially U-shaped moving frame 21 is movably mounted on the bottom plate 20. That is, the moving frame 21 is substantially U-shaped as shown in FIG. 9, and is provided with long holes 22 extending in the length direction on the left and right portions. Each of the long holes 22 receives a roller 23. A rack 26 is attached to the moving frame 21, and the rack 26 meshes with the drive gear 27. The drive gear 27 is interlocked with a worm 30 attached to the output shaft of the motor 29 via a gear train 28.

  Next, the front panel 15 will be described. As shown in FIGS. 4 to 6, the front panel 15 is provided with pins 35 on the lower end side and on both the left and right sides. The pins 35 are connected to the connecting holes 34 of the arms 33 on both sides of the moving frame 21.

  Also, arms 40 are attached to the left and right portions of the upper end side of the front panel 15, and pins 41 are implanted in these arms 40. The pin 41 is received in a guide groove 42 provided inside the left and right side walls of the sub-panel 11 shown in FIGS. 7 and 8, and is moved substantially vertically along the guide groove 42. It has become so. Moreover, the guide groove 42 has an upper end portion formed from a rear bent portion 43 and a lower end portion formed from a front bent portion 44.

  Next, the extrusion operation of the front panel 15 according to the above configuration will be described. As shown in FIGS. 1 and 10, the front panel 15 is held in a substantially vertical posture in a state in which the rear side is received by the sub-panel 11 attached to the front end side of the chassis 10 in the housed state. On the other hand, by driving a motor 29 provided on the bottom plate 20 of the chassis 10 to push the front panel 15 to the front end side through the moving frame 21, the front panel 15 is moved as shown in FIGS. The panel 15 is extruded so as to face obliquely upward, and at this time, the upper end portion of the sub-panel 11 is exposed, and thereby the slit insertion opening 12 is opened. Therefore, the optical disc can be inserted into and ejected from the optical disc player in the chassis 10 through the slit insertion opening 12.

  Next, the pushing operation of the front panel 15 will be described with reference to FIGS. As shown in FIG. 10, when the motor 29 is rotationally driven with the front panel 15 being housed and held in the sub-panel 11, the rotation of the motor 29 is transmitted to the drive gear 27 via the worm 30 and the gear train 28. . Accordingly, the drive gear 27 pushes the rack 26. Accordingly, the moving frame 21 including the rack 26 is pushed rightward in FIG. 10, and for this reason, the moving frame 21 is also moved rightward while being guided by the rollers 23.

  Since the pins 35 on both lower ends of the front panel 15 are connected to the connection holes 34 of the arms 33 on both sides of the moving frame 21, the movement of the moving frame 21 causes the lower end side of the front panel 15 to move. The part moves to the right. This state is gradually performed as shown in FIGS.

  In synchronism with the movement of the lower end portion of the front panel 15, the pin 41 of the arm 40 on the upper end side of the front panel 15 moves downward along the guide groove 42 on the side wall of the sub panel 11. For this reason, the front panel 15 is pulled forward while gradually increasing its inclination angle. That is, the front panel 15 is pushed out while gradually changing the inclination angle so as to be inclined obliquely upward.

  11 and 12 in the initial stage of the pivoting operation, the pin 41 of the arm 40 on the upper end side of the front panel 15 moves from the rear bent part 43 of the guide groove 42 to the middle up and down. Move to the part that extends in the direction. Therefore, by such a moving operation, the portion on the upper end side of the front panel 15 performs the operation of being pushed forward and rightward in the drawing.

  Due to the action of the rear bent portion 43, the front panel 15 hardly rotates in the counterclockwise direction around the upper end portion of the guide groove 42 in the initial stage of pushing out the front panel 15. For this reason, the upper edge of the front panel 15 is less likely to come into contact with the lower edge of the upper portion of the mounting frame 48 that is fixedly attached to the instrument panel. Therefore, a sudden increase in load due to interference between the upper end of the front panel 15 and the mounting frame 48 is avoided, and the pushing operation is thereby smoothly performed. Further, since the front panel 15 does not interfere with the mounting frame 48, a sudden load is not applied to the motor 29, whereby the front panel 15 gradually changes to the state shown in FIGS. Thus, a stable extrusion operation is achieved. Further, since the front panel 15 is less likely to interfere with the lower edge of the upper portion of the mounting frame 48, it is not necessary to set a large clearance between the mounting frame 48 and the front panel 15, thereby avoiding deterioration in design. It becomes like this.

  Next, a modification will be described with reference to FIGS. 16 and 17. In this modification, the shape of the guide groove 42 provided on the side wall portions on both sides of the sub-panel 11 is changed, and an extremely short region on the upper end side of the guide groove 42 is used as the rear bent portion 43. Yes. The rest of the configuration is the same as in the above embodiment.

  According to such an embodiment, in the first stage of the operation of driving the motor 29 to push out the front panel 15, the pin 41 on the upper end side of the front panel 15 moves forward substantially horizontally from the rear bent portion 43. Thereafter, an operation of moving downward is performed. That is, during the initial operation of the front panel 15 that is most likely to interfere with the mounting frame 48, the upper end portion of the front panel 15 does not rotate but mainly performs a linear motion to the right in the figure. . Therefore, interference between the upper edge of the front panel 15 and the mounting frame 48 is avoided. Accordingly, even with such a configuration, substantially the same operational effects as the above-described embodiment can be obtained.

  Although the present invention has been described above with reference to the illustrated embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea of the present invention. For example, the embodiment described above relates to an in-vehicle device having an optical disk player therein, but such an in-vehicle device may be an in-vehicle device for reproducing music or video, or also writing map software.
