  The in-dash type car navigation device is provided with an installation panel corresponding to the vehicle type for attachment to various vehicles. When an in-dash type car navigation device is attached to a vehicle, an attachment panel corresponding to the vehicle type is used. When viewed from the side of the vehicle, in order to be able to attach a plurality of types of in-dash type car navigation devices to one vehicle type, the instrument panel at the mounting portion of the car navigation device can be detached independently. Thus, an attachment panel corresponding to the car navigation device can be attached. Thereby, when the car navigation device is mounted, an instrument panel in which the mounting panel and the other part of the instrument panel are harmonized can be configured. The surface of the mounting panel constitutes a part of the instrument panel design surface, in particular, the instrument panel design surface around the display.

  FIG. 6 is a side view of a 2DIN car navigation device with a 7-inch display embedded in a dashboard. In FIG. 6, the dashboard is shown in cross section. The car navigation apparatus 100 is configured by attaching a 7-inch display 102 to the front surface of a 2DIN size car navigation apparatus main body 101 having a substantially rectangular parallelepiped shape.

  The display 102 has a slide pin 103 on the top thereof. The car navigation device main body 101 is formed with a guide rail 104 for guiding the slide pin 103 in the vertical direction. Further, the display 102 is provided with a pin 106 for pivotally supporting the tip of the movable arm 105 at the lower part thereof. The movable arm 105 moves in and out of the front and the depth by a motor and a drive mechanism (not shown) provided in the car navigation apparatus main body 101.

  When the slide pin 103 at the top of the display 102 is guided by the guide rail 104 and the tip of the movable arm 105 is pivotally supported by the pin 106, the movable arm 105 slides in the front-rear direction, so that the display 102 is And a posture c (hereinafter referred to as a “maximum tilted posture”).

  The guide rail 104 is formed from the position of the slide pin 103 when the display 102 is in the upright posture a to the position of the slide pin 103 when the display 102 is in the maximum tilted posture c. 103 stops at the lower end of the guide rail 104, so that the display 102 stops in the maximum tilting posture c. A slot for a medium such as a disk or a memory card is provided in the upper half of the front surface of the car navigation apparatus main body 101. When the medium is inserted or removed, the display 102 is tilted to the maximum tilting posture c.

  The car navigation device main body 101 is attached to an attachment portion 201 provided on the dashboard 200. Here, as shown in FIG. 6, in a general vehicle, the mounting direction (in the direction of arrow A) of the car navigation device main body 101 with respect to the dashboard 200 (that is, the upper surface, the left and right side surfaces, and the lower surface of the car navigation device main body 101 The extending direction) and the direction of the instrument panel design surface 202 (arrow B direction) are not perpendicular to each other, but are inclined at an angle of several degrees or twenty degrees from the vertical. Accordingly, when the car navigation device main body 101 is attached to the attachment portion 201 and the display 102 is set in the upright posture, an angle difference is generated between the instrument panel design surface 202 and the screen of the display 102.

  FIG. 7 is an external view showing an angle difference between the instrument panel design surface 202 and the screen of the display 102 when the display 102 is in an upright posture. If an angle difference is generated between the instrument panel design surface 202 and the screen of the display 102, not only the design is impaired, but various buttons 107 are provided below the screen of the display 102 as shown in FIG. Since it is provided, there arises a problem that it is difficult to operate the button 107 below the screen of the display 102.

  Therefore, in the conventional car navigation apparatus, the display 102 is movable between the posture b shown in FIG. 6 (hereinafter referred to as “corrected fixed posture”) and the maximum tilting posture c. That is, when the display 102 is returned from the maximum tilting posture c to the standing direction by the operation of the button 107 from the maximum tilting posture c or the like, it is stopped at the corrected fixed posture b, and is further raised to stand upright. Do not return to a. Then, normal navigation, TV viewing, etc. are performed with this corrected fixed posture b. Here, the upright posture a is a mechanical end when the display 102 is returned to the standing direction (a limit in which the movement is mechanically limited), whereas the corrected fixed posture b is a soft end (the motion is moved by software). Limit).

  FIG. 8 is an external view showing a state in which the display 102 is in the corrected fixed posture b. The corrected fixed posture b, which is a soft end, can be set by a user or an installer depending on the angle relationship between the instrument panel design surface 202 and the mounting portion 201 of each of a plurality of types of vehicles. In addition, a plurality of soft ends are preset for a plurality of types of vehicles, and the corrected fixed posture b is set by the user or the installer selecting one from a plurality of preset soft ends according to the type of vehicle. May be.

  Thus, by making it possible to set the corrected fixed posture b according to the type of vehicle, it is not necessary to prepare a car navigation device for each type of vehicle, and versatility can be ensured. , Design and manufacturing costs can be reduced. When the car navigation device is attached to a plurality of types of vehicles each having a 2DIN attachment portion, the instrument panel design surface 202 and the display 102 are substantially flush with each other as shown in FIG. Thus, it is possible to avoid a decrease in design and operability due to an angle difference between the instrument panel design surface 202 and the surface of the display 102.

  The display of a car navigation device tends to be enlarged, and for example, the demand for a display size of 8 inches or more is increasing. However, the size of the main body of the car navigation device needs to be a size determined by the standard of 2DIN, and cannot be increased with an increase in the size of the display. For this reason, the following problems arise.

  FIG. 9 is a side view of a 2DIN car navigation device with an 8-inch display embedded in a dashboard. In FIG. 9, the dashboard is shown in cross section. The dashboard 200 is provided with a mounting portion 201 for accommodating the 2DIN car navigation device main body 101 as in the example of the 7-inch display (see FIG. 6). The display panel 102 is extended downward as compared with the case of the 7-inch case. Therefore, the dashboard 200 has a space for this purpose.

  However, since the height of the movable arm 105 is limited to the size of the 2DIN car navigation apparatus body, the distance between the lower end of the display 102 and the pin 106 that rotatably supports the movable arm 105 is increased. Then, in order to make the surface of the display 102 flush with the instrument panel design surface 202, the pins 106, 103 are driven by the lever principle by the operation of the button 107 or the vibration caused by the running of the vehicle when used in the corrected fixed posture b. A heavy load will be applied to this. This causes a problem that the corrected fixed posture b of the display is shifted.

  Since the fixed fixed posture b is a soft end, gear backlash occurs in the drive mechanism of the movable arm 105. However, in the case of an 8-inch display, the display is larger than the main body of the 2DIN car navigation device, and the movable arm 105 is Since the pin 106 is extended downward from the supporting pins 106, there is a problem that the vibration of the display is increased and the rattle noise is increased as compared with the case of the 7-inch display.

  The above problem is not limited to an 8-inch display, and the problem increases as the display size increases. Further, not only when a large-screen display of 8 inches or more is used, but even with a display of a size of 7 inches or less, the same problem occurs when the soft end is in a fixed fixed posture.

  In view of this, the present invention provides a car navigation device in which the display is used in a corrected fixed posture slightly tilted along the instrument panel design surface. An object of the present invention is to provide a car navigation device that can reduce the occurrence of rattle abnormal noise.

  According to this configuration, when the display is tilted with respect to the car navigation device main body so as to be along the instrument panel design surface of the dashboard, that is, the corrected fixed posture, the tilt adjustment component is connected to the car navigation device main body and the display. Therefore, it is possible to reduce the generation of rattle noise due to the deviation of the corrected fixed posture and the vibration of the display. This tilt adjustment component uses a fixed fixed posture, which has been a conventional soft end, as a mechanical end. That is, the tilt adjustment component mechanically restricts the display from moving in the erect direction beyond the fixed fixed posture.

  In the car navigation device, the height of the display may be larger than the height of the car navigation device main body, and the car navigation device main body includes an escutcheon extended downward on a surface corresponding to the display. The tilt adjustment component may be sandwiched between the lower end portion of the display and the lower end portion of the escutcheon.

  According to this configuration, it is possible to reduce the occurrence of rattle noise due to the deviation of the corrected fixed posture and the vibration of the display even for a large display.

  In the car navigation device, the tilt adjusting component may be fixed to a lower end portion of the escutcheon.

  According to this configuration, it is possible to reduce the occurrence of rattle noise due to the deviation of the corrected fixed posture and the vibration of the display without increasing the weight of the tilting display.

  In the car navigation device, the upper end of the display may be slidable in the vertical direction along a surface corresponding to the display of the main body of the car navigation device, and the car navigation device includes a movable arm. The movable arm may be a movable arm whose tip is pivotally supported by the display so as to be slidable in the front-rear direction within the main body of the car navigation device. The car navigation device main body and the display may be sandwiched below the movable arm.

  According to this configuration, even when a load is applied by a button operation or the like below the movable arm support portion of the display in a corrected fixed posture, the load is received by the tilt adjustment component. Can reduce the load.

  In the car navigation device described above, the tilt adjustment component may include a buffer member on the side opposite to the side on which the tilt adjustment component is held.

  According to this configuration, for example, when the tilt adjustment component is held on the car navigation device main body side, the buffer member is provided on the display side, and when the display is in the corrected fixed posture, the display is tilt adjustment component. Therefore, the generation of rattle abnormal noise due to the vibration of the display can be reduced more favorably. The buffer member may be a rubber member, for example.

  Another aspect of the present invention is a tilt adjustment component used in a car navigation device including a car navigation device main body embedded in a dashboard and a display tiltable with respect to the car navigation device main body. When held by either the navigation device main body or the display and sandwiched between the car navigation device main body and the display, the display is aligned with the instrument panel surface of the dashboard. It is designed to have a tilted posture.

  According to this configuration, when the display is tilted with respect to the car navigation device main body so as to be along the instrument panel design surface of the dashboard, that is, the corrected fixed posture, the tilt adjustment component is connected to the car navigation device main body and the display. Therefore, it is possible to reduce the generation of rattle noise due to the deviation of the corrected fixed posture and the vibration of the display.

  In the present invention, the tilt adjustment component is sandwiched between the car navigation device main body and the display when the display is tilted with respect to the car navigation device main body so as to be along the instrument panel design surface of the dashboard, i.e., the corrected fixed posture. Therefore, it is possible to reduce the occurrence of abnormal rattle noise due to deviation of the corrected fixed posture and vibration of the display.
