Description

  The present invention relates to an in-vehicle device such as a car navigation device mounted on a vehicle such as an automobile.

In general, as an in-vehicle device such as a car navigation device mounted on a vehicle such as an automobile, a display unit and a main body unit are connected to each other so as to be relatively movable, and displayed to the user in order to improve the visibility of the user. There has been proposed one in which the direction and distance of the part can be made variable. (See Patent Document 1)
JP 2001-280979 A

  However, in such an in-vehicle device, since the part that slides the display unit in the vertical direction is supported on both sides of the display unit, the horizontal length of both sides of the display unit becomes long, and the screen itself Compared to the above, the length of the display portion in the left-right direction has to be long, so that there is a problem that it is difficult to make the device compact.

  At the same time, since the portions for sliding the display unit in the vertical direction are supported on both sides of the display unit, it is difficult to slide the display unit in the vertical direction while rotating the display unit, and the operability for the user is improved. There was a problem that I could not.

  Furthermore, since the part for rotating the display unit and the part for sliding the display unit in the vertical direction are configured by the same link mechanism, the positioning accuracy in the rotation direction and the vertical direction of the display unit is reduced, and the user As a result, the operability could not be improved. And since the rigidity which supports a display part to an up-down direction cannot be enlarged, the stability of a display part cannot be improved during driving | running | working, but there existed a problem that a user's visibility could not be improved.

  In view of the above problems, an object of the present invention is to provide an in-vehicle device that can be made compact and can improve user operability and visibility.

In order to solve the above problem, the in-vehicle device according to the present invention is:
A vehicle-mounted apparatus comprising a display unit, a main body unit, and a connecting unit that connects the display unit to the main body unit so as to be relatively movable,
The connecting portion is

A second direction slide portion supported by the first direction slide portion and slidable along a second direction perpendicular to the first direction;
A rotation support unit supported by the second direction slide unit and configured to rotatably support the display unit about an axis perpendicular to the first direction and the second direction. .

  ADVANTAGE OF THE INVENTION According to this invention, the vehicle-mounted apparatus which can be reduced in size and can improve a user's operativity and visibility can be provided.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a schematic view showing an embodiment of a car navigation apparatus according to the present invention, and FIGS. 2 to 5 are schematic views showing a part of an embodiment of a car navigation apparatus according to the present invention.

  The car navigation apparatus 1 includes a display 2, a housing 3, and a connecting portion 4 that connects the display 2 to the housing 3 so as to be relatively movable.

  The display 2 may be a liquid crystal display, for example. The display 2 displays an image such as a map display or a TV under the control of a control device (not shown). Alternatively, the display 2 may display an operation screen for operating the in-vehicle device. Further, the display 2 is a touch panel display and may also serve as an operation device.

  The housing 3 accommodates, for example, a storage medium (for example, a DVD disk) for storing map data and a control device (not shown). A storage medium outlet may be provided on the front surface of the housing 3. The housing 3 may be disposed together with the connecting portion 4 described below, for example, inside the instrument panel so that only the front surface can be seen from the outside.

  Further, the connecting portion 4 is supported by the casing 3, the vertical slide portion 5, the front / rear slide portion 6 supported by the vertical slide portion 5, and the front / rear slide portion 6 supporting the display 2 to the left and right. A rotation support portion 7 that is rotatably supported around the direction axis is configured. Here, the vertical direction, the front-rear direction, and the left-right direction are directions based on the vehicle.

  As shown in FIG. 3, the vertical slide portion 5 has a vertical hole 9 formed at the front end of a rectangular parallelepiped slider 8 that is long in the front-rear direction, and a female screw on the inner peripheral surface at the rear end. A vertical screw hole 10 is formed, and a shaft-shaped guide 11 extending in the vertical direction is fitted into the vertical hole 9 with play, and a ball screw 12 extending in the vertical direction is screwed into the vertical screw hole 10. Composed. Although not shown here, both end portions of the guide 11 are supported and fixed to flange portions provided at the upper end portion and the lower end portion of the lateral end surface of the housing 3, and the ball screw 12 is the upper end portion of the lateral end surface of the housing 3. And it is supported so that rotation with respect to the flange part provided in the lower end part is possible. A pair of vertical slide portions 5 are provided symmetrically on the outer side in the left-right direction of the housing 3. When the ball screw 12 is rotated manually or by an actuator, the pair of left and right sliders 8 are moved in the vertical direction.

  As shown in FIG. 1, the front-rear direction slide part 6 extends in the front-rear direction, and has the above-described vertical direction slide part 5 on the support arm 13 having a hole portion having a sawtooth portion extending in the front-rear direction when viewed from the left-right direction. Two cylindrical protrusions 14 projecting outward in the left-right direction from the left-right end face of the slider 8 are configured to fit with play. A pair of front-rear direction slide portions 6 is also provided symmetrically on the outer side in the left-right direction of the housing 3.

  Further, as shown in FIGS. 1 and 3, the rotation support portion 7 includes an outer pin hole 15 provided in the front end portion of the pair of support arms 13 and extending in the left-right direction, and left and right ends of the lower end portion of the display 2. A pair of left and right inner pin holes 16 (located on the back surface of the outer pin hole 15 in FIG. 1) and two pairs of the outer pin holes 15 and the inner pin holes 16 that are provided on the outer side in the right direction. And a pair of pins 17 extending in the left-right direction that are fitted so as to have resistance. When the user pushes the upper end portion of the display 2 in the front-rear direction, the display 2 is moved in the front-rear direction based on the restraint of the front-rear direction slide unit 6, and when the user rotates the display 2 in the front-rear direction, the rotation support portion The display 2 is rotated around the pin 17 based on the constraint of 7.

  With the connecting portion 4 described above, the user can freely move the display 2 relative to the housing 3 from the storage position indicated by 2a in FIG. Visibility can be enhanced by setting the display 2 in a direction that is easy to see for the user.

  In addition, since the vertical slide portions 5 for sliding the display 2 in the vertical direction are supported on both end surfaces of the housing 3 in the horizontal direction, the vertical slide portions are provided on both sides in the horizontal direction of the display 2 as in the prior art. In comparison, it is possible to shorten the lengths of the portions located on the left and right sides of the screen of the display 2. This eliminates the need to configure the length of the display 2 in the left-right direction longer than that of the screen itself, so that the device can be easily downsized. Moreover, since the slide stroke in the vertical direction can be increased, the operability and visibility of the user can be improved thereby.

  At the same time, as in the prior art, it is possible to eliminate the configuration in which the part for sliding the display 2 in the vertical direction is provided on both sides in the horizontal direction of the display 2, so the display 2 is rotated with respect to the support arm 7. In this state, it is possible to slide in the vertical direction on the basis of the restraint of the vertical slide portion 5, and the operability for the user can be improved.

  Furthermore, since the rotation support part 7 that rotates the display 2 and the vertical slide part 5 that slides the display 2 in the vertical direction are configured by separate link mechanisms, the rotation of the display 2 is faster than that of the conventional technique. The accuracy of positioning in the moving direction and the vertical direction can be increased. Thereby, user convenience and operability can be improved.

  In addition, since the rigidity for supporting the display 2 in the vertical direction can be increased, the support stability of the display 2 can be improved during traveling. Also by this, a user's visibility can be improved. Further, here, the rotation support portion 7 is provided at the lower end portion of the end surface in the left-right direction of the display 2, but it can also be provided at the center portion of the display 2. However, in this case, since the stroke of the vertical slide portion 5 becomes small, the configuration shown in this embodiment is more advantageous.

  Further, when the display 2 is rotated forward in order to insert a storage medium such as a DVD disk into the housing 3 of the car navigation apparatus 1, the display 2 can be rotated after being moved upward in advance. In the case where there is a shift lever or the like behind the car navigation device 1, it is possible to prevent the display 2 and the shift lever from interfering with each other.

  Furthermore, when there is an air-conditioner outlet above the car navigation device 1, the display 2 is moved backward and rotated while the vertical position of the display 2 is positioned downward. 2 can prevent the air outlet of the air conditioner from being blocked.

  In the embodiment shown in FIG. 3, the vertical slide portion 5 is constituted by a ball screw. However, as shown in FIG. 4, a cylindrical vertical hole is formed at the front end of the cuboid slider 8 that is long in the front-rear direction. 9 is drilled, a rectangular column-shaped vertical hole 18 is drilled at the rear end, a shaft-shaped guide 10 is fitted with play in the vertical hole 9, and a rack shaft is mounted in the vertical hole 18. A pinion shaft (not shown) that engages with the rack shaft 19 and a knob or an actuator that rotates the pinion shaft may be provided. Again, a pair of vertical slide parts 5 are provided symmetrically on the outside in the left-right direction of the housing 3. Here, both ends of the guide 10 are supported by the housing 3, and both ends of the rack shaft 19 are supported by the housing 3. When the pinion shaft is rotated manually or by an actuator, the pair of left and right sliders 8 are moved in the vertical direction based on the engagement between the pinion shaft and the rack shaft 19.

  Further, in the embodiment shown in FIG. 3, the vertical slide portion 5 is constituted by a ball screw. However, as shown in FIG. The pulleys 22 and 23 that respectively support the front and rear wires 20 and 21 are provided above the left and right end surfaces of the housing 3 by connecting one ends of the wires 20 and 21. It is good also as a structure which provides the pulley 24 which supports both the two wires 20 and 21 above an edge part, and the reel 25 which winds up the wires 20 and 21 below the pulley 24 is provided. Again, a pair of vertical slide parts 5 are provided symmetrically on the outside in the left-right direction of the housing 3. When the reel 25 is rotated manually or by an actuator in the winding direction, the pair of left and right sliders 8 are moved in the vertical direction.

  In addition, in the embodiment shown in FIG. 3, the above-described upper and lower sliding portions 6 extend in the front-rear direction, and the support arm 13 having a hole portion having a saw-tooth portion extending in the front-rear direction when viewed from the left-right direction is provided on the upper and lower sides. Two cylindrical protrusions 14 projecting outward in the left-right direction from the left-right end face of the slider 8 of the direction slide part 5 are configured to fit with play. As an alternative configuration, a rack portion 13 a may be formed on the support arm 13, and a pinion shaft 26 that engages with the rack portion 13 a may be provided so as to protrude outward in the left-right direction from the left-right end surface of the slider 8. When the pinion shaft 26 is rotated manually or by an actuator, the display 2 is moved in the front-rear direction based on the engagement between the pinion shaft 26 and the rack portion 13a.

  Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions are made to the above-described embodiments without departing from the scope of the present invention. be able to. In this embodiment, the first direction is the vertical direction and the second direction is the front-rear direction. However, the first direction may be the left-right direction and the second direction may be the front-rear direction. In this case, since the axial direction of the pin 17 constituting the rotation support portion 7 is the vertical direction, the display 2 can be rotated about the vertical direction as an axis. It is also possible to adopt a configuration in which the first direction is the front-rear direction and the second direction is the up-down direction.

  Moreover, in the said Example, the vehicle-mounted apparatus shall be the car navigation apparatus 1, the housing | casing 3 shall be equipped with the control apparatus of the car navigation apparatus 1, and the housing | casing 3 is set as the "main-body part" in an attached claim.
