Description

  The present invention relates to an in-vehicle display device installed on a dashboard or the like of a vehicle, and in particular, the display unit is tilted horizontally from a state in which the display unit is upright on the front surface of the main body to open the front surface, or the angle of the display unit is increased. The present invention relates to an in-vehicle display device that can be tilted to make it easy for a user to see.

  In recent years, in-vehicle navigation devices have become widespread. This in-vehicle navigation device is generally installed on a dashboard. At this time, in order to make the display unit of the in-vehicle navigation device easy to see, it is necessary to tilt only the display unit at an optimum angle while the in-vehicle navigation device is fixed to the dashboard.

  Therefore, conventionally, for example, a technique shown in Patent Document 1 below has been proposed. This is displayed on in-vehicle navigation equipment by a chassis whose back is housed and fixed in the dashboard and a support that is pivotally connected to the front of the chassis and supports the display from below. The part is rotatably supported. Furthermore, it has means for fixing the rotation position of the display unit at a desired angle. The fixing means includes a substantially U-shaped holding plate having a sliding surface that is attached to the back surface of the display unit and that is in sliding contact with the side frame of the chassis, a first pin that projects from a lower portion of the sliding surface, A plurality of mounting holes arranged at predetermined intervals on the upper surface of the surface, a second pin attached to the mounting hole, and a first pin and a second pin are inserted and slidably fitted vertically And a fitting groove formed in the side frame.

  As a result, the display unit is fixed by attaching the second pin to the attachment hole via the fitting groove at a desired rotation position. For example, the display unit can set an upward and downward state at an arbitrary angle from an upright state.

  Therefore, even when the mounting angle of the in-vehicle display device with respect to the vehicle main body is different due to different types of vehicles or different mounting locations, the display unit can be changed to an angle that is easy for the user to see.

In addition, in order to make it possible to change functions recently, it is possible to load a new optical disk, for example, an optical disk on which navigation map information is recorded, into an optical disk drive built in an in-vehicle display device. There is. In such a vehicle-mounted display device, the front of the device main body is opened by tilting the display unit to a horizontal position so that an optical disk can be loaded into the optical disk drive.

  By the way, in-vehicle display devices mounted on a vehicle are often attached without protruding from the surface of the dashboard so that the display unit does not hit the knees or belongings of a person riding in the vehicle. However, when the above-mentioned in-vehicle display mount device is mounted with the display unit completely embedded in the dashboard and rotated to tilt the display unit downward, the display unit has a lower end portion at the rear as a fulcrum. Therefore, the front lower edge of the display unit is displaced downward from the extension line of the lower surface of the chassis when viewed from the side. Therefore, unless a gap is provided in advance between the lower surface of the display unit and the lower side of the dashboard mounting opening, the front lower edge of the display unit abuts against the dashboard, and the display unit cannot be tilted downward. Further, if a gap is provided between the lower surface of the display unit and the lower side of the opening for attaching the dashboard, there is a problem that it is not preferable in terms of aesthetics and dust prevention.

  By the way, the above-mentioned problem can be solved if the front lower end of the display unit can be rotated as a fulcrum, but providing a shaft at the front lower end of the display unit ensures a space in the structure of the display unit. Because it is difficult, it is virtually impossible.

  The present invention has been made in view of the above problems, and the inventors fixed a movable chassis having a predetermined width on the rear surface of the display unit, and fixed the movable chassis to a vertical sliding body in a freely rotatable manner. An operation restricting member is provided in the vertical part in front of the device main body of the in-vehicle display device, and the lower end part of the vertical sliding body movably attached to the slide base is moved further backward from the position where the display unit is in the upright state. If it is pulled horizontally, the movable chassis member comes into contact with the operation restricting member, and the movable chassis member and the display section virtually move the lower end portion in front of the display section by moving the lower section backward and the upper section moving forward. Since it tilts so as to rotate as a fulcrum, it has been found that the lower end of the display unit does not protrude downward from the bottom surface of the in-vehicle display device, and the present invention has been achieved.

  That is, the present invention provides an in-vehicle display device having a display unit that can be opened and closed and can be tilted to an optimum display angle as described above, and between the lower surface of the display unit and the lower side of the dashboard mounting opening. It is an object of the present invention to provide an in-vehicle display device that eliminates the conventional problems and does not require a gap.

  Another object of the present invention is to prevent the display unit from projecting from the bottom surface of the in-vehicle display device when the display unit is tilted to the optimum display angle, and without restricting the space of the display unit. An object of the present invention is to provide an in-vehicle display device capable of providing a pivot point for rotation at the front lower end of the display unit.

  A movable chassis 10 is fixed on the rear surface of the display unit 9. 6A and 6B are side views of the movable chassis of the in-vehicle display device according to the present invention. FIG. 6A is a side view of the movable chassis as viewed from the outside of the apparatus main body, and FIG. It is a side view at the time of seeing from the inner side of a main body.

  The movable chassis 10 has a rectangular thin plate portion that has a predetermined width and height substantially the same size as the display unit 9 and is attached to the rear surface of the display unit 9, and side portions that protrude vertically rearward on both sides thereof. And is a substantially U-shaped member as viewed from above. As shown in FIG. 6, each side portion has a predetermined width length and thickness, and a first guide groove 101 is formed at a predetermined depth on the inner surface of the upper portion thereof. Further, a second guide slot 102 is provided in the lower part of the movable chassis 10 so as to penetrate from the inner surface to the outer surface. Further, the front surface 108 of the movable chassis 10 is provided with a plurality of protrusions 104 protruding vertically from the front surface 108, and the protrusions 104 are fitted into recesses formed so as to correspond to the rear surface of the display unit 9. Thus, the movable chassis 10 is fixed to the rear surface of the display unit 9.

  The first guide groove 101 and the second guide slot 102 formed in the movable chassis 10 are each formed in an arc shape having the same center point 103. The arc-shaped first guide groove 101 and the second guide slot 102 have a center point 103 outside the movable chassis 10 as shown in FIG. 6B, but their positions are as shown in FIG. When the movable chassis 10 is attached to the display unit 9, the movable chassis 10 is positioned at the front end of the lower end of the display unit 9. For this purpose, the curvature and arc length of the first guide groove 101 and the second guide slot 102 are set. , And the position is determined.

  The movable chassis 10 is attached to the vertical side plate 5 which is a fixed portion of the in-vehicle display device 1 with the following configuration. That is, the first guide groove 101 and the opening 75 above the intermediate portion 72 of the vertical sliding body 7 are aligned and connected by the connecting member 106 such as an axial pin, and the second guide slot 102 and the vertical sliding body 7 are connected. The opening 76 provided above the lower portion 73 is aligned and connected by a connecting member 107 such as a shaft pin. Then, since the first guide groove 101 and the second guide slot 102 of the movable chassis 10 are each arcuate, the vertical sliding body 7 and the movable chassis 10 are connected so as to be relatively rotatable within a predetermined range. . Further, the vertical sliding body 7 is engaged with the vertical guide 6 by a connecting member 78 at the upper part and is further rotatably connected to the slide base 8 by a connecting member 11 at the lower part. The movable chassis 10 is assembled to be movable with respect to the vertical side plate 5 and the horizontal side plate 3.

  The movable chassis 10 has a rear surface 109 positioned below the first guide groove 101 and above the second guide slot 102. Further, a spring mounting hole 105 is provided in the central portion of the side portion of the movable chassis 10.

  A roller 12 as an operation restricting member is attached to the inner surface of the vertical side plate 5. The roller 12 is pivotally supported on the vertical side plate 5 by attachment means such as a shaft pin. The roller 12 is installed in the vicinity of the lower center of the vertical side plate 5, and faces the rear surface 109 of the movable chassis 10 by a predetermined gap when the display unit 9 is upright. Further, the roller 12 is attached to the vertical plate 5 so as to be positioned below the first guide groove 101 and above the second guide slot 102.

  In the present embodiment, the roller 12 is used as the operation restricting member. However, any other shape may be used as long as it restricts the movement of the movable chassis 10, and it can be used by appropriately changing. However, when a roller is used, the rear surface 109 can smoothly rotate along the outer peripheral surface of the roller when the rear surface 109 of the movable chassis 10 comes into contact with the roller 12 as will be described later. preferable. It is also possible to prevent damage caused by the rear surface 109 of the movable chassis 10 coming into contact with the roller.

  As shown in FIG. 3A, a torsion spring 13 is attached between the movable chassis 10 and the vertical sliding body 7. That is, one end of the torsion spring 13 is fixed to the spring mounting hole 105 of the movable chassis 10 with a fixing member such as a screw, and the other end is also fixed to the vertical sliding body 7 with a fixing member or the like. As a result, the torsion spring 13 biases the display unit 9 to which the movable chassis 10 is attached toward the vertical sliding body 7, and is perpendicular to the display unit 9 when the display unit 9 is upright or horizontal. The direction sliding body 7 is moved together.

  In this embodiment, the torsion spring 13 is used as an urging means for urging the movable chassis 10 so as to be parallel to the vertical sliding body 7. Thus, it becomes possible to configure the biasing means. Furthermore, a relatively large biasing force can be generated by the torsion spring. Obviously, biasing means other than the torsion spring 13, such as a coil spring, may be used.

  The operation of the on-vehicle display device 1 described above will be described below. The disk drive storage space 26 provided inside the device main body 2 of the in-vehicle display device 1 stores a drive unit such as a motor, a control circuit for controlling the drive unit, and the like. It operates according to an instruction set and input by the user from the operation input means. The setting input instruction by the user may be from other than the operation input means of the display unit 9 such as a remote controller or a voice instruction. The on-vehicle display device 1 may be driven by a power source other than the motor.

  The display unit 9 of the in-vehicle display device 1 is in an upright state illustrated in FIGS. 1 to 3, a horizontal state illustrated in FIGS. 7 and 8, and an inclination (reverse tilt) illustrated in FIGS. 9 and 10 according to a user instruction. Three positions of the state can be taken.

  As shown in FIGS. 1 to 3, when the display unit 9 is in the upright state, the slide base 8 is pulled backward along the horizontal guide provided on the horizontal side plate 3, and therefore the vertical sliding body 7 Since the lower end portion is connected to the connecting portion 82 of the slide base 8, the lower end portion is positioned at the lower end portion of the vertical side plate 5. The upper end portion of the vertical sliding body 7 can be slid along the vertical guide 6 by the connecting member 78. At this time, the upper end portion of the vertical sliding body 7 is located at the upper end portion of the vertical side plate 5.

  Next, the operation when the opening 25 is exposed by tilting the display unit 9 to the horizontal state so that the disk drive built in the disk drive storage space 26 can be accessed will be described. FIG. 7 is an external perspective view of the in-vehicle display device when the display unit is tilted to the horizontal state. FIG. 8 is a side view of the in-vehicle display device shown in FIG.

  When the slide base 8 is fed forward along the horizontal guide by a drive mechanism including a motor or the like housed inside the device main body 2 of the in-vehicle display device 1, the slide base 8 and the connecting portion 82 are located in front of the device main body 2 and the automobile. Projects forward from the dashboard. Since the lower end portion of the vertical sliding body 7 is connected to the connecting portion 82 of the slide base 8 by the connecting member 11, and the upper end portion can move only along the vertical guide 6, the vertical sliding body 7 is connected to the slide base 8. Along with the movement, the lower end part moves forward and the upper end part descends along the vertical guide 6 to the lower end of the vertical guide, whereby the vertical sliding body 7 rotates about the connecting member 11 and is substantially Become horizontal.

  At this time, the upper opening 75 of the intermediate portion 72 of the vertical sliding body 7 is engaged with the first guide groove 101 of the movable chassis 10 by the connecting member 106, and the upper opening 76 of the lower portion 73 of the vertical sliding body 7 is formed. Since the connecting member 107 is engaged with the second guide slot 102 of the movable chassis 10 and the movable chassis 10 and the vertical sliding body 7 are biased by the torsion spring 13, the movable chassis 10 has the vertical sliding body 7. As it rotates about the connecting member 11, it moves together with the vertical sliding body 7 until it becomes substantially horizontal, and the display unit 9 is tilted to the horizontal state. At this time, the display unit 9 moves so that the lower end is pulled forward from the dashboard of the automobile, and the upper end moves so as to descend while rotating around the rear of the lower end to reach a horizontal state. .

  As a result, an opening 25 behind the display unit 9 appears, and a recording medium such as a DVD-ROM can be inserted into or removed from the disk drive installed in the disk drive storage space 26 inside the device body 2 through the opening 25. It becomes possible.

  Next, an operation in a tilt state (reverse tilt state) in which the display unit 9 is tilted downward by a predetermined angle in order to obtain a suitable display angle will be described. FIG. 9 is an overall external perspective view when the display unit is in a tilted state (reverse tilt state) in the in-vehicle display device according to the embodiment of the present invention. FIG. 10 is a side view of the in-vehicle display device shown in FIG. 9, where FIG. 10 (a) is a side view when the side plate is removed and viewed from the outside, and FIG. 10 (b) is a view when viewed from the inside. FIG. 10C is a side view when the vertical sliding body is removed and viewed from the inside.

  In the upright state shown in FIGS. 1 to 3, when the slide base 8 is further pulled back along the horizontal guide by a drive mechanism such as a motor, the connecting portion 82 of the slide base 8 is more than in the upright state. Move backwards slightly. Since the lower end portion of the vertical sliding body 7 is connected to the connecting portion 82 of the slide base 8, the lower end portion moves slightly rearward along with the rearward movement of the slide base 8, and the upper end portion thereof is the vertical guide 6. However, at this time, there is no path that can be moved along with the backward movement of the slide base 8, so the upper end portion does not move from the upper end of the vertical guide 6. Therefore, the lower end portion of the vertical sliding body 7 is pulled rearward and is slightly rotated rearward about the upper end portion.

  At this time, the opening 76 provided above the lower portion 73 of the vertical sliding body 7 and the connecting member 107 inserted therethrough move rearward, but the connecting member 107 is moved to the second guide slot 102 of the movable chassis 10. Therefore, the movable chassis 10 moves rearward, and the rear surface 109 of the movable chassis 10 contacts the roller 12. When the slide base 8 is further moved rearward, the lower part of the vertical sliding body 7 is moved rearward accordingly, and the movable chassis 10 is further moved rearward. Therefore, the movable chassis 10 as a whole cannot move backward any further. However, since the movable chassis 10 is engaged with the vertical sliding body 7 below the contact portion with the roller 12, as the lower part of the vertical sliding body 7 moves rearward, Only the lower part is pulled and moved rearward, the contact portion of the movable chassis 10 with the roller 12 rotates while sliding along the outer peripheral surface of the roller 12, and the upper part of the movable chassis 10 moves forward.

  At this time, the movable chassis 10 rotates around a virtual fulcrum (center point 103) existing at the lower front portion of the display unit 9. This is because the first guide groove 101 and the second guide slot 102 provided in the movable chassis 10 are each formed in an arc shape centering on the center point 103, and the middle part and the lower part of the vertical sliding body 7 are formed on them. This is made possible by inserting the connecting members 106 and 107 engaged with the openings 75 and 76 of the first and second openings. When the lower surface of the movable chassis 10 is pulled rearward with the rear surface 109 of the movable chassis 10 in contact with the roller 12, as described above, the contact portion of the movable chassis 10 with the roller 12 is the outer peripheral surface of the roller 12. The upper part of the movable chassis 10 moves forward, but at this time, the movable chassis 10 is engaged with the middle and lower openings 75 and 76 of the vertical sliding body 7. The central point 103 is rotated as a virtual fulcrum so that the connecting members 106 and 107 move relatively in the first guide groove 101 and the second guide slot 102.

  In this way, the display unit 9 is inclined obliquely downward with the front lower end as the center, so the center of the tilting operation of the display unit 9 is the front lower end of the display unit, and the lower end of the display unit is from the bottom surface of the device body 2. Does not protrude downward.
