  However, in the conventional panel tilting mechanism, a slider having a sawtooth shape is connected to the panel, and the slider is urged by a spring in a direction to open the panel, so that any one of the teeth of the sawtooth of the slider is attached. The lever that directly engages and regulates the position of the slider is released by operating the operation button operated by the user, and the angle of the panel can be adjusted by changing the position of the slider. For this reason, when the operation button is kept pressed, the state where the engagement between the saw blade of the slider and the lever is maintained, the slider moves at a stroke and the panel is opened, and the angle of the panel is adjusted. However, appropriate timing and subtle adjustment are necessary for the operation of the operation buttons, and there is a problem in operability.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to improve the operability when adjusting the angle of the panel in the panel retractable mechanism of the in-vehicle electronic device.

In order to achieve the above object, the present invention comprises a panel on the front surface of a housing, the lower end of the panel slides forward, the upper end of the panel is displaced downward, and the panel can be tilted in the front-rear direction. In the panel retractable mechanism of the on-vehicle electronic device configured, biasing means for biasing the lower end of the panel forward, and displacement means for displacing the upper end of the panel downward, independent of the biasing means. And the displacement means displaces the upper end of the panel downward stepwise by operating an operation button.
According to this configuration, since the displacement means for displacing the upper end of the panel downward is provided independently of the urging means for urging the lower end of the panel forward, the upper end of the panel is urged by the operation of the operation button. Independently of the above operation, it can be displaced downward stepwise, and the tilt angle of the panel can be manipulated stepwise. As a result, the panel angle can be adjusted step by step in response to the pressing operation of the operation button, so that the operation of the operation button is not required to be delicately adjusted, and the operability of the panel angle adjustment can be improved.

Further, in the above configuration, the displacement means includes a swing lever that has one end connected to the upper end of the panel and the other end swingably supported by the housing to support the panel tiltably. A sawtooth-shaped portion may be provided on the swing lever, and a link that engages the tooth portion of the sawtooth-shaped portion may be provided, and the engagement state between the link and the tooth portion may be operated by operating the operation button. .
According to this configuration, the panel can be operated by operating the engagement state between the sawtooth portion provided on the swing lever connected to the upper end of the panel and the link that engages the tooth portion of the sawtooth portion by the operation button. The tilt angle can be manipulated step by step. As a result, the panel angle can be adjusted stepwise in response to the pressing operation of the operation button, so that the operation of the operation button need not be delicately adjusted, and the operability of the panel angle adjustment can be improved.

Further, the saw-tooth shaped portion has first and second saw-tooth shaped portions, and the link has first and second links respectively engaged with the first and second saw-tooth shaped portions, and the operation button is operated. When the engagement between the first link and the tooth portion of the first sawtooth shape portion is released, the second link and the tooth portion of the second sawtooth shape portion may be engaged to hold the sawtooth shape portion.
In this case, when the engagement between the first link and the tooth portion of the first sawtooth shape portion is released by the operation of the operation button, the second link and the tooth portion of the second sawtooth shape portion are engaged to form a sawtooth shape. Since the panel is held, the panel is not tilted at a stroke when the operation button is operated. For this reason, it is not necessary to perform subtle operation adjustments on the operation of the operation buttons, and the operability of panel angle adjustment can be improved.

Further, when the panel is pushed back against the urging direction of the urging means, the swing lever is lifted to close the panel, and the saw-tooth shaped portion is lifted together with the swing lever. On the other hand, the engaging part may be a retractable type.
In this case, the panel can be manually closed simply by pushing back the panel against the urging direction of the urging means. Further, since the engaging portion is tiltable with respect to the direction in which the saw-tooth shaped portion rises and the engaging portion does not prevent the saw-tooth shaped portion from being raised when the panel is closed, the panel can be closed smoothly.

Furthermore, the urging means is urged so as to slide in the forward direction, and is provided in the casing so as to be able to advance and retreat, and a front portion is connected to a lower end of the panel to support the panel in a tiltable manner. A slider may be provided.
In this case, since the lower end of the panel is supported by the slider which can be moved forward and backward in the housing, the panel can be freely opened and closed.

FIG. 4 is a side view showing the panel tilting mechanism 20 in a state where the operation button 16 is pressed. FIG. 5 is a side view showing the panel retractable mechanism 20 when the operation button 16 is released from the state shown in FIG.
Here, the operation of the panel tilting mechanism 20 will be described with reference to FIGS. 2, 4 and 5.
First, as shown in FIG. 2, when the panel 13 is fully closed, the panel 13 is substantially upright and closes the insertion slot 12. In this state, the swinging lever 21 receiving the biasing force swinging downward by the lever biasing spring 33 is moved downward by engaging the lower first tooth portion 28 </ b> A with the front claw portion 38 of the link 24. Oscillation is restricted and the closed state of the panel 13 is maintained. Further, since the movement of the swing lever 21 is restricted and the upper connecting shaft 26 is not displaced downward, the lower connecting shaft 30 of the slider 23 has a force that moves on an arc centering on the upper connecting shaft 26. I can't move forward horizontally. As a result, the forward movement of the slider 23 is restricted, and the closed state of the panel 13 is maintained.

Next, when the operation button 16 is pressed and pushed in the closed state, as shown in FIG. 4, the pressed portion 47 is pressed via the pressing portion 16 </ b> B, and the link 24 is centered on the link support shaft 41. It rotates in the clockwise direction. Accordingly, the front claw portion 38 is displaced forward and the engagement between the front claw portion 38 and the lower surface of the lower first tooth portion 28A is released, and the lower surface of the lower first tooth portion 28A and the lower second tooth portion 29A. The rocking lever 21 is moved down together with the saw-tooth shaped portion 22 by a level difference from the lower surface of the first and second claw portions 39 displaced forward are engaged with the lower surface of the lower second tooth portion 29A. In this state, the front end 38B of the front claw portion 38 is located between the inclined surface 48 of the lower first tooth portion 28A and the lower surface of the middle first tooth portion 28B. The tip 38 </ b> B is formed in a tapered shape that is smaller than the interval between the tooth portions of the first sawtooth-shaped portion 28.
Here, when the state in which the operation button 16 is pushed in is maintained by the user pressing the operation button 16 for a long time, the engagement between the rear claw portion 39 and the lower second tooth portion 29A is only maintained. Yes, even if the operation button 16 continues to be pressed, the angle of the swing lever 21 does not change.

  Thereafter, when the pressing of the operation button 16 is released and the pressing portion 16B is displaced forward, the link 24 is pulled by the tension spring 43 and rotated counterclockwise around the link support shaft 41 as shown in FIG. And return to the original position. Along with this, the rear claw portion 39 of the link 24 is displaced rearward and the engagement between the rear claw portion 39 and the lower surface of the lower second tooth portion 29A is released, and the front end 38B of the front claw portion 38 is connected to the introduction portion 49. Slides on the inclined surface 48 of the lower first tooth portion 28A and enters between the lower second tooth portion 29A and the middle first tooth portion 28B, and the swing lever 21 is moved to the middle first tooth portion 28B. The lower surface is lowered until it engages with the upper surface of the front claw portion 38.

  That is, in the panel retractable mechanism 20, when the operation button 16 is pressed once, the first sawtooth-shaped portion 28 is lowered by one step. When the first sawtooth-shaped portion 28 is lowered by one step, the upper connecting shaft 26 of the swing lever 21 swings downward by an amount corresponding to the height of the first sawtooth-shaped portion 28 and the slider 23. Becomes slidable forward, and the lower connecting shaft 30 slides forward substantially horizontally. Accordingly, the panel 13 is tilted backward and tilted so that the display unit 14 faces upward by the upper connecting shaft 26 and the lower connecting shaft 30 that are displaced in conjunction with the downward swing of the swing lever 21. The swinging lever 21 is tilted and opened by an angle corresponding to the amount that the swing lever 21 is lowered by one step.

  Subsequently, when the operation button 16 is further pressed once from the state in which the middle first tooth portion 28B is engaged with the front claw portion 38, similarly, the upper second portion is accompanied by the backward swing of the link 24. The tooth portion 29B engages with the rear claw portion 39, and then the upper first tooth portion 28C engages with the front claw portion 38 as the link 24 swings forward as the operation button 16 is released. The rocking lever 21 is lowered until the tilt angle of the panel 13 in the opening direction increases.

FIG. 6 is a side view showing the panel tilting mechanism 20 when the panel 13 is fully opened.
When the operation button 16 is pressed again, the front claw portion 38 is displaced forward as the link 24 swings backward, and the engagement between the front claw portion 38 and the upper first tooth portion 28C is released. The sawtooth-shaped portion 22 is lowered through the opening 40, and the swing lever 21 is lowered to the lower limit position as shown in FIG. As a result, the tilt angle of the panel 13 in the opening direction is further increased, and the panel 13 is fully opened.

As described above, in the panel retractable mechanism 20 according to the present embodiment, the open state is adjusted to a total of four stages, that is, fully open, fully closed, and two stages between fully open and fully closed by manually operating the operation button 16. In addition, since the angle of the panel 13 can be adjusted stepwise in accordance with the number of pressing operations of the operation button 16, the operation of the operation button 16 does not need to be delicately adjusted, and the operability of adjusting the angle of the panel 13 can be improved. . Moreover, since the angle of the panel 13 can be adjusted to a desired angle, the visibility and operability of the touch panel display unit 14 can be easily adjusted according to the user's preference. Furthermore, since the angle of the panel 13 can be adjusted stepwise by a manual pressing operation, and a motor or a drive mechanism as a drive source for opening and closing the panel 13 is not necessary, a panel tilting mechanism capable of adjusting the angle of the panel 13 is provided. This can be realized with a simple configuration.
Further, since the swing lever 21 is lowered by one step by the reciprocating swing operation of the link 24 in the front-rear direction by one press of the operation button 16, even if the state where the operation button 16 is pressed is maintained. The swing lever 21 does not descend at once, but descends by one step. As a result, the tilt angle of the panel 13 is not affected by the time period during which the operation button 16 is pressed, so that the operation of the operation button 16 does not require delicate operation adjustment, and the operability of adjusting the angle of the panel 13 can be improved.

FIG. 7 is a side view showing a state of the panel tilting mechanism 20 when the panel 13 is closed. The panel 13 is manually pushed backward by the user's hand or the like against the urging force of the slider 23 in a state where the operation button 16 is pressed by the user or the like and the link 24 is tilted backward. It is closed with.
That is, as shown by the arrow in FIG. 7, when the panel 13 is pushed backward, the lower connecting shaft 30 moves horizontally and the upper connecting shaft 26 moves upward and the panel 13 is closed. . At this time, the sawtooth portion 22 of the swing lever 21 swinging upward together with the upper connecting shaft 26 enters the housing portion 34 of the link 24 through the opening 40, and the lower first tooth portion 28 </ b> A becomes the front claw portion 38. Thus, the panel 13 is maintained in the fully closed state. Specifically, when the swing lever 21 is swung upward, the inclined surfaces 48 of the first sawtooth shape portion 28 and the second sawtooth shape portion 29 are formed on the introduction portions 49 of the front claw portion 38 and the rear claw portion 39. The saw-tooth shaped portion 22 makes contact with the inclined surface 48 of the first saw-tooth shaped portion 28 and the second saw-tooth shaped portion 29 so that the front claw portion 38 and the rear claw portion 39 are pushed away, and the link 24 is slightly rotated back and forth. It moves into the accommodating part 34, moving it.

In the present embodiment, the rear claw portion 39 is pivotally supported by the shaft 39A and urged counterclockwise by the torsion coil spring 39B, and the sawtooth-shaped portion 22 rises and enters the housing portion 34. It is configured to be retractable in any direction. Accordingly, when closing the panel 13, the rear claw portion 39 is pushed upward by the second sawtooth-shaped portion 29 to enlarge the opening 40, and the sawtooth-shaped portion 22 can be easily passed through the housing portion 34. The panel 13 can be closed smoothly by simply pushing the 13 backward.
Further, since the introduction portion 49 is inclined upward in accordance with the inclined surfaces 48 of the first sawtooth shape portion 28 and the second sawtooth shape portion 29, the first sawtooth shape portion 28 and the second sawtooth shape portion 29 are introduced to the introduction portion. The saw-tooth shaped portion 22 can smoothly enter the accommodating portion 34 by being guided by 49.

  As described above, according to the embodiment to which the present invention is applied, the displacement means 80 for displacing the upper end of the panel 13 downward independently of the urging means 70 for urging the lower end of the panel 13 forward. Therefore, by operating the operation button 16, the upper end of the panel 13 can be displaced downward stepwise independently of the operation of the biasing means 70, and the tilt angle of the panel 13 can be manipulated stepwise. As a result, the angle of the panel 13 can be adjusted stepwise in response to the pressing operation of the operation button 16, so that the operation of the operation button 16 does not require delicate operation adjustment, and the operability of the angle adjustment of the panel 13 can be improved. .

In addition, the relationship between the sawtooth shape portion 22 provided on the swing lever 21 connected to the upper end of the panel 13 and the link 24 that engages the first sawtooth shape portion 28 and the second sawtooth shape portion 29 of the sawtooth shape portion 22. By operating the combined state with the operation button 16, the tilt angle of the panel 13 can be operated stepwise.
