Description

  The present invention relates to an opening / closing device for a front panel of an in-vehicle electronic device.

  In in-vehicle electronic devices such as car navigation systems, car audio systems, and in-vehicle TVs, the display panel is provided on the front surface of the electronic device body, and the display panel is tilted forward to expose the front surface of the electronic device body, By standing, the front surface of the electronic device main body is hidden behind the display panel (see, for example, Patent Document 1). However, when the display panel is tilted forward, there is a problem that the display surface of the display panel faces downward and the user cannot visually recognize the display surface of the display panel.

  Therefore, the present applicant provides the lower end portion of the display panel so that it can be moved back and forth, and provides the upper end portion of the display panel so that it can be moved up and down, and then tilts the display panel so that the display surface of the display panel faces upward. Technology is being developed (for example, Japanese Patent Application Nos. 2004-303775 and 2004-315204).

Specifically, as shown in FIG. 11, the slider 204 is provided so as to be movable back and forth with respect to the chassis 203, and an intermediate portion of the swinging rod 206 is rotatably connected to the front end portion of the slider 204. The lower end portion of the display panel 202 is rotatably connected to the front end portion of the swinging rod 206, and a bow-shaped guide groove 207 is provided at the front end portion of the chassis 203. The upper end portion of the display panel 202 is vertically moved by the guide groove 207. Guided. The swing rod 206 is urged counterclockwise by the torsion spring 205, and a sliding roller 210 is provided at the rear end of the swing rod 206. A roller guide 208 is provided behind the sliding roller 210 and an inclined surface 209 is formed on the roller guide 208. The inclined surface 209 is formed so as to face obliquely downward at the front and downward toward the rear. In this device, when the slider 204 moves forward, the display surface of the display panel 202 falls down so that the display surface faces upward, and when the slider 204 moves backward, the display surface of the display panel 202 moves forward. Stand up to face. When the slider 204 moves further rearward from the state in which the display panel 202 stands, the sliding roller 210 slides on the inclined surface 209, so that the swing rod 6 rotates clockwise. As a result, the lower end portion of the display panel 202 is lifted rearward, the upper end portion of the display panel 202 moves diagonally forward and the display panel 202 faces forward with the display surface of the display panel 202 facing diagonally downward. Fall down.

  By the way, in a state where the display surface of the display panel 202 faces obliquely downward, the sliding roller 210 is pressed against the inclined surface 209 upward by the torsion spring 205. Accordingly, even with slight vibration, the sliding roller 210 moves forward along the inclined surface 209 by the force generated by the weight of the display panel 202, and the swing rod 206 is rotated counterclockwise by the torsion spring 205 to swing. The slider 204 moves forward together with the flange 206. For this reason, the display surface of the display panel 202 cannot be held in a state of facing forward and obliquely downward. It is not preferable to provide a mechanical or electrical brake mechanism for stopping the display panel 202 in a state where the display panel 202 is tilted forward, because the apparatus becomes larger and the number of components increases.

  Accordingly, the present invention has been made in order to solve the above-described problems, and an object of the present invention is to maintain a front panel such as the display panel 202 in a predetermined posture such as a forward-turning posture without using a brake mechanism. Objective.

The second inclined surface 83 is also inclined so as to descend downward, and is inclined more greatly than the first inclined surface 81. Further, a stopper 85 protruding downward is formed at the lower end of the roller guide 8. The stopper 85 is behind the claw 52 of the second slider 5.

  As shown in FIGS. 1 and 2, when the pin 21 of the display panel 2 is vertically guided by the vertical guide portion 72, the sliding roller 61 moves forward from the first inclined surface 81 and the second inclined surface 83. The claw 52 is moved forward away from the stopper 85 and the second slider 5 can be moved back and forth integrally with the first slider 4 by the tension spring 91. The edge is in contact with the lower surface of the lock pin 62, and the lower surface of the front end portion of the swing rod 6 is in contact with the front end portion of the first slider 4 at point A.

  As shown in FIG. 2, when the pin 21 of the display panel 2 is positioned at the upper end portion of the vertical guide portion 72, the movement of the second slider 5 to the rear is suppressed by the claw 52 coming into contact with the stopper 85. Thus, the first slider 4 is separate from the second slider 5 and can move rearward.

  As shown in FIGS. 2 and 3, when the pin 21 of the display panel 2 moves from the vertical guide portion 72 to the horizontal guide portion 73, the first slider 4 is separated from the second slider 5 by the claw 52. The lock pin 62 is moved rearward from the lock protrusion 53 of the second slider 5 and the swinging rod 6 is urged counterclockwise by the torsion spring 92, whereby the slide roller 61 is moved. Is in contact with the first inclined surface 81, and the sliding roller 61 slides on the first inclined surface 81, so that the swing rod 6 can rotate around the connecting shaft 63.

  As shown in FIG. 3, when located at the rear end of the lateral guide portion 72 of the display panel 2, the sliding roller 61 is in contact with the holding surface 82.

  As shown in FIGS. 3 and 4, when the pin 21 of the display panel 2 is guided back and forth by the lateral guide portion 73, the first slider 4 is separated from the second slider 5 by the claw 52. The swing roller 6 is biased counterclockwise by the torsion spring 92 so that the sliding roller 61 comes into contact with the second inclined surface 83, and the sliding roller 61 moves the second inclined surface 83. By sliding, the swing rod 6 can rotate around the connecting shaft 63.

  As shown in FIG. 4, when the pin 21 of the display panel 2 is located at the front end of the lateral guide portion 73, the sliding roller 61 is in contact with the horizontal holding surface 84.

  The pin 21, the first slider 4, the second slider 5, the swing rod 6, the sliding roller 61, the lock pin 62, the guide plate 7, the roller guide 8, the tension spring 91, the torsion spring 92, etc. are displayed. They are provided symmetrically on the left and right sides of the panel 2. The first sliders 4 on both sides have an integral structure.

Next, the operation of the opening / closing device 1 will be described.
As shown in FIG. 1, in a state where the first slider 4 extends forward from the chassis 3, the pin 21 of the display panel 2 is positioned at the lower end of the guide 71, and the display panel 2 falls back to display. The display surface 22 of the panel 2 faces upward. Further, the claw 52 of the second slider 5 is located at a position farther forward than the stopper 85 of the roller guide 8, and the sliding roller 61 of the swing rod 6 is the first inclined surface 81 and the holding surface 82 of the roller guide 8. The second inclined surface 83 and the horizontal holding surface 84 are located away from the roller guide 8. Further, the lower surface of the front end portion of the swing rod 6 is in contact with the front end portion of the first slider 4 at point A, thereby preventing the swing rod 6 from rotating counterclockwise. The lock pin 62 comes into contact with the upper edge of the lock protrusion 53, and this prevents the rocking rod 6 from rotating clockwise. As described above, since the swing rod 6 does not rotate in either direction, rattle noise of the display panel 2 can be prevented, and the visibility of the display panel 2 is improved.

  When the first slider 4 slides backward by the drive mechanism, the swinging rod 6 also moves rearward together with the first slider 4, and the pin 21 of the display panel 2 moves along the vertical guide portion 72 of the guide 71. As a result, the display panel 2 stands up, and the display surface 22 of the display panel 2 faces forward. At this time, the second slider 5 is also moved rearward together with the first slider 4 by being pulled rearward by the tension spring 91, and the lock pin 62 of the swing rod 6 is in contact with the upper edge of the lock protrusion 53. And the state where the front end portion of the swing rod 6 is in contact with the front end of the first slider 4 is maintained.

  As shown in FIG. 2, when the pin 21 is positioned at the upper end portion of the vertical guide portion 72, the sliding roller 61 comes into contact with the front end portion of the first inclined surface 81, and the claw 52 of the second slider 5 becomes the roller. The stopper 8 is brought into contact with the stopper 85 of the guide 8 and locked. Therefore, when the first slider 4 slides further backward by the driving mechanism, the rearward movement of the second slider 5 is suppressed, the lock pin 62 is separated from the upper edge of the lock protrusion 53, and the swing rod 6 is moved. It can be rotated clockwise.

  When the first slider 4 is moved further rearward by the drive mechanism, the sliding roller 61 slides on the first inclined surface 81, and the swing rod 6 rotates clockwise against the torsion spring 92, and the display panel While the lower end of 2 moves rearward and upward, the display panel 2 stands up so that the display surface 22 of the display panel 2 faces forward. As shown in FIG. 3, when the sliding roller 61 is positioned on the holding surface 82, the display surface 22 of the display panel 2 faces forward. FIG. 6 is a view showing a state of the swing rod 6 in the state of FIG. As shown in FIG. 6, in a state where the display panel 2 stands and the sliding roller 61 is positioned on the holding surface 82, a line segment B connecting the sliding roller 61 and the connecting shaft 63 is parallel to the holding surface 82. Therefore, even if the sliding roller 61 is pressed against the holding surface 82 by the torsion spring 92, no component force is generated in a direction parallel to the holding surface 82.

  When the first slider 4 moves further rearward by the drive mechanism, the sliding roller 61 slides on the second inclined surface 83, and the swing rod 6 rotates clockwise against the torsion spring 92. Thereby, the lower end part of the display panel 2 moves rearward and upward, the pin 21 moves forward along the lateral guide part 73, and the display panel 2 falls forward.

  When the first slider 4 is moved further rearward by the drive mechanism, the sliding roller 61 is positioned on the horizontal holding surface 84 and the pin 21 is positioned on the front end portion of the lateral guide portion 73 as shown in FIG. The display surface 22 of the display panel 2 faces forward and obliquely downward. FIG. 7 is a view showing a state of the swing rod 6 in the state of FIG. As shown in FIG. 7, when the display panel 2 is tilted forward and the sliding roller 61 is positioned on the horizontal holding surface 84, the line segment B connecting the sliding roller 61 and the connecting shaft 63 is parallel to the horizontal holding surface 84. It becomes. Therefore, even if the sliding roller 61 is pressed against the horizontal holding surface 84 by the torsion spring 92, no component force is generated in a direction parallel to the horizontal holding surface 84.

  When the first slider 4 is moved forward by the drive mechanism from the state of FIG. 4, the sliding roller 61 moves from the horizontal holding surface 84 to the second inclined surface 83, and the sliding roller 61 is inclined second by the torsion spring 92. The second inclined surface 83 is slid while being pressed against the surface 83. As a result, the swing rod 6 rotates counterclockwise, the lower end portion of the display panel 2 moves forward and downward, the pin 21 moves rearward along the lateral guide portion 73, and the display panel 2 stands up. . At this time, since the second slider 5 is pulled backward by the tension spring 91, even if the first slider 4 moves forward, the second slider 5 does not move forward.

  When the first slider 4 is moved forward by the drive mechanism from the state of FIG. 3 in which the sliding roller 6 reaches the holding surface 82, the sliding roller 61 is pressed against the first inclined surface 81 by the torsion spring 92. Then, the first inclined surface 81 is slid, the swing rod 6 is rotated counterclockwise, and the display panel 2 is moved backward so that the display surface 22 of the display panel 2 faces upward.

  When the first slider 4 is further moved forward by the drive mechanism, the lock pin 62 comes into contact with the upper edge of the lock projection 53 and the front end of the swing rod 6 is located on the first slider 4 as shown in FIG. Abuts the front end. In addition, since the tension spring 91 has a natural length in the state of FIG. 2, when the first slider 4 is moved forward by the drive mechanism from the state of FIG. 2, the second slider 5 is integrated with the first slider 4. Move forward. At this time, the lower end portion of the display panel 2 moves forward, the pin 21 moves downward along the vertical guide portion 72, and the display panel 2 moves backward. When the first slider 4 moves to the previous limit position, the pin 21 of the display panel 2 is positioned at the lower end of the guide 71, and the display surface 22 of the display panel 2 faces upward (see FIG. 1).

  As described above, according to the present embodiment, when the sliding roller 61 is in contact with the holding surface 82 as shown in FIG. 6, the sliding roller 61 is pressed against the holding surface 82 by the torsion spring 92. No component force is generated in the direction parallel to the holding surface 82. Therefore, the sliding roller 61 does not move, the swinging rod 6 does not rotate, and the first slider 4 does not move forward, so that the posture in which the display panel 2 stands is maintained. Since the attitude of the display panel 2 can be maintained without using a brake mechanism, it is possible to suppress an increase in the size of the switchgear 1 and an increase in the number of components.

  Similarly, when the sliding roller 61 is in contact with the horizontal holding surface 84 as shown in FIG. 7, no component force is generated in a direction parallel to the horizontal holding surface 84, so that the display panel 2 is tilted forward. Can be maintained.

  8 to 10 are diagrams showing roller guides 8A, 8B, and 8C as modified examples. 8 to 10, the same reference numerals are given to the same portions as those of the roller guide 8 described above. In the roller guide 8A, the holding surface 84A continuous to the rear end of the second inclined surface 83 is recessed upward in a triangular shape, and in the roller guide 8B, the holding surface 84B continuous to the rear end of the second inclined surface 83 is arcuate. In the roller guide 8C, a holding surface 84C continuous to the rear end of the second inclined surface 83 is recessed upward in a rectangular shape. When such a roller guide 8A, roller guide 8B or roller guide 8C is fixed to the side plate of the chassis 3 instead of the roller guide 8, the sliding roller 61 is held when the pin 21 is positioned at the front end of the lateral guide portion 73. It enters into the recess of the surface 84A, the holding surface 84B or the holding surface 84C. Therefore, since the sliding roller 61 does not move, the swinging rod 6 does not rotate, and the first slider 4 does not move forward, the posture in which the display panel 2 is tilted forward can be maintained.

  The present invention is not limited to the above embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.

  In the above embodiment, the display panel 2 has been described as an example of the front panel. However, a lid panel that covers the front surface of the electronic device body may be used as the front panel.

  Further, instead of the torsion spring 92, a plate spring may be used to urge the swing rod 6 counterclockwise. A compression spring may be used instead of the tension spring 91, but in the case of a compression spring, the spring hook 41 of the first slider 4 is in front of the spring hook 51 of the second slider 5.

  Further, although the stopper 85 is formed on the roller guide 8, it may be formed on the side plate 32 of the chassis 3 as long as it can be engaged with the claw 52. Further, although the guide 71 is formed on the guide plate 7 fixed to the chassis 3, it may be formed directly on the chassis 3.

  In the above-described embodiment, the holding surface 82 and the horizontal holding surface 84 are formed on the roller guide 8 in order to maintain the display panel 2 in a standing posture and a tilted posture. The holding surface may be formed on the roller guide 8 so that when the sliding roller 61 comes into contact with the holding surface, a line segment B connecting the sliding roller 61 and the connecting shaft 63 is parallel to the holding surface. . For example, when the first inclined surface 81 is divided into two front and rear inclined surfaces, the two inclined surfaces are connected by a holding surface, and the sliding roller 61 contacts the holding surface, the connecting roller 61 and the connecting shaft If the line segment B connecting 63 is parallel to the holding surface, the display panel 2 can be maintained in a tilted posture when the sliding roller 61 is in contact with the holding surface.
